PRESENTATION OF FINANCIAL INFORMATION

We maintain our books and records in reais. We prepared our consolidated financial statements included in this annual report in accordance with IFRS as issued by the IASB (“IFRS”).

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying our accounting policies. Those areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements, are disclosed in Note 3 to our consolidated financial statements.

Our financial statements prepared in accordance with IFRS as of December 31, 2017 and December 31, 2016 and for the years ended December 31, 2017, December 31, 2016 and December 31, 2015 have also been filed with the CVM, the local securities regulator in Brazil and made publicly available. Our selected financial information included in “Item 3. Key Information—A. Selected Financial Data” should be read in conjunction with, and is qualified in its entirety by, our financial statements and “Item 5. Operating and Financial Review and Prospects” appearing elsewhere in this annual report.

The consolidated financial statements as of December 31, 2017 and 2016 and for each of the three years in the period ended December 31, 2017 are in compliance with IFRS, as issued by the IASB and also with the pronouncements, interpretations and guidance issued by the IASB and the IFRS Interpretations Committee, or the IFRIC, which entered into force as of January 1, 2017.

We have made rounding adjustments to reach some of the figures included in this annual report. Accordingly, numerical figures shown as totals in some tables may not be an arithmetic aggregation of the figures that preceded them.

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 as of that or any other date. In addition, translations should not be construed as representations that the real amounts represent or have been or could be converted into U.S. dollars as of that or any other date.

(2)   As of the date of this annual report, we held 1,688,693,776 outstanding shares, composed of common and preferred shares, net of 2,291,147 treasury shares.

Exchange Rates

The Central Bank allows the real/U.S. dollar exchange rate to float freely and has intervened to control the exchange rate volatility. However, the exchange market may continue to be volatile, and the real may depreciate or appreciate substantially in relation to the U.S. dollar. The Central Bank or the Brazilian government may intervene in the exchange rate market.

Since 1999, the Central Bank has allowed the real/U.S. dollar exchange rate to float freely, and, since that time, the real/U.S. dollar exchange rate has fluctuated considerably. In 2013, 2014 and 2015, the real depreciated 14.6%, 13.4% and 47.0%, respectively, against the U.S. dollar. In 2016, the real appreciated 16.5% against the U.S. dollar. In 2017, the real depreciated 1.5% against the U.S. dollar, ending the year at an exchange rate of R$3.3080 per US$1.00.

The Brazilian government has implemented various economic plans and utilized a number of exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments ranged from a daily to a monthly basis), floating exchange rate systems, exchange controls and dual exchange rate markets.  We cannot predict whether the Central Bank or the Brazilian government will continue to let the real float freely or intervene in the exchange rate market by returning to a currency band system or otherwise.  The real may depreciate or appreciate substantially against the U.S. dollar.

D.    Risk Factors

This section is intended to be a summary of more detailed discussions contained elsewhere in this annual report. The risks described below are not the only ones we face. Additional risks that we do not presently consider material, or of which we are not currently aware, may also affect us. Our business, results of operations or financial condition could be impacted if any of these risks materializes and, as a result, the market price of our preferred shares and our ADSs could be affected.

Risks Relating to Brazil

The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy. This influence, as well as Brazilian political and economic conditions, could adversely affect us and the trading price of our preferred shares and ADSs.

The Brazilian federal government frequently exercises significant influence over the Brazilian economy and occasionally makes significant changes in policy and regulations. The Brazilian government’s actions to control inflation and other policies and regulations have often involved, among other measures, changes in interest rates, changes in tax policies, wage and price controls, foreign exchange controls, currency devaluations, capital controls and limits on imports. Our business, financial condition, results of operations and the market price of our preferred shares and ADSs may be adversely affected by changes in government policies, especially those related to our sector, such as changes in telephone fees and competitive conditions, as well as general economic factors, including:

3

·exchange rates and currency fluctuations;

·exchange controls and restrictions on remittances abroad, (including with regards to the payment of dividends) such as those imposed in 1989 and early 1990;

·growth or downturn of the Brazilian economy;

·inflation;

·energy policy;

·interest rates and monetary policies;

·liquidity of domestic capital and lending markets;

·fiscal policies and changes in tax laws;

·economic, political or social instability;

·labor and social security policies, laws and regulations; and

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

Uncertainty over whether the Brazilian federal government will implement changes to the policies, regulations or standards affecting these or other factors in the future may affect economic performance and contribute to economic uncertainty in Brazil, which may have an adverse effect on us and the trading price of our preferred shares and ADSs. Recent economic and political instability has led to a negative perception of the Brazilian economy and higher volatility in the Brazilian securities markets, which also may adversely affect us and the trading price of our preferred shares and ADSs.

 The ongoing economic uncertainty and political instability in Brazil may adversely affect the Brazilian economy, our business, and the market price of our preferred shares and ADSs.

Brazil’s political environment has historically influenced, and continues to influence, the performance of the country’s economy. Political crises have affected and continue to affect the confidence of investors and the general public, which have historically resulted in economic deceleration and heightened volatility in the securities issued by Brazilian companies.

The recent economic instability in Brazil has contributed to a decline in market confidence in the Brazilian economy as well as to a deteriorating political environment. In addition, various ongoing investigations into allegations of money laundering and corruption being conducted by the Office of the Brazilian Federal Prosecutor, including the largest such investigation, known as “Operação Lava Jato,” have negatively impacted the Brazilian economy and political environment. Certain members of the Brazilian federal government and of the legislative branch, as well as senior officers of large state-owned companies, are facing allegations of political corruption for officials allegedly accepting bribes by means of kickbacks on contracts granted by the government to several infrastructure, oil and gas and construction companies. A number of senior politicians, including members of Congress, and high-ranking executives officers of major corporations and state-owned companies in Brazil have been arrested, convicted of various charges relating to corruption, entered into plea agreements with federal prosecutors and/or have resigned or been removed from their positions. The potential outcome of Operação Lava Jato as well as other ongoing corruption-related investigations is uncertain, but they have already hurt the image and reputation of those companies that have been implicated as well as the general market perception of the Brazilian economy, political environment and the Brazilian capital markets. We have no control over, and cannot predict, whether such investigations or allegations will lead to further political and economic instability or whether new allegations against government officials will arise in the future.

Former President Dilma Rousseff was suspended from office on May 12, 2016, when the Brazilian Senate voted to hold a trial on impeachment charges against her. Ms. Rousseff was replaced by Vice-President Michel Temer, who served as acting President until Ms. Rousseff was permanently removed from office by the Senate on August 31, 2016 for infringing budgetary laws. Michel Temer then became President for the remainder of the presidential term, until the next general elections, scheduled for October of 2018. In June 2017, the Brazilian Higher Electoral Court (Tribunal Superior Eleitoral) cleared the electoral alliance formed by Ms. Rousseff and Mr. Temer of charges that it had violated campaign finance laws in the 2014 election. President Temer remains the subject of investigations by the Brazilian Federal Police and the Office of the Brazilian Federal Prosecutor relating to allegations of corruption, however, and may ultimately be subject to impeachment proceedings before his presidential term ends. We cannot predict whether these investigations and lawsuits will bring about further economic and political instability or if new allegations against high officers of the Brazilian federal Government will arise in the future. In addition, we cannot predict the results of any such investigations, including their effects over the Brazilian economy. The development of such cases may negatively affect us and the price of our preferred shares and ADSs.

Furthermore, uncertainty over whether the acting Brazilian government will implement changes in policy or regulation in the future may contribute to economic uncertainty in Brazil and to heightened volatility in the securities issued abroad by Brazilian companies. The Brazilian government may be subject to internal pressure to change its current macroeconomic policies, including its fiscal policy, in order to achieve higher rates of economic growth and/or meet its fiscal targets. We cannot foresee what policies or actions the Brazilian government may pursue or adopt. Moreover, uncertainty with respect to the upcoming presidential elections may increase the volatility in the financial markets.

Any of the above factors may create additional political uncertainty, adversely affect the Brazilian economy, our business, financial condition, results of operations and the market price of our preferred shares and ADSs.

Inflation and government efforts to curb inflation may contribute to economic uncertainty in Brazil, adversely affecting our business and results of operations.

In the past, Brazil has experienced extremely high rates of inflation. Inflation and some of the measures taken by the Brazilian government in an attempt to curb inflation have had significant negative effects on the Brazilian economy generally. Inflation, policies adopted to curb inflationary pressures and uncertainties regarding possible future governmental intervention have contributed to economic uncertainty and heightened volatility in the Brazilian capital markets.

According to the National Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo), or IPCA, Brazilian inflation rates were 6.3%, 10.7% and 6.4% in 2016, 2015 and 2014, respectively. In 2017, inflation as measured by the IPCA fell to 2.9%. Brazil may experience high levels of inflation in the future and inflationary pressures may lead to the Brazilian government’s intervening in the economy and introducing policies that could harm our business and the price of our preferred shares and ADSs. In the past, the Brazilian government’s interventions included the maintenance of a restrictive monetary policy with high interest rates that restricted credit availability and reduced economic growth, causing volatility in interest rates. For example, the SELIC (Sistema Especial de Liquidação e de Custódia), the Central Bank’s overnight rate, as established by the Monetary Policy Committee of the Central Bank (Comitê de Política Monetária do Banco Central do Brasil—COPOM), increased from 10.00% at the beginning of 2014 to a high point of 14.25% in 2016 before a series of reductions in 2017, bringing the SELIC rate down to 6.75% as of February 7, 2018. Conversely, more lenient government and Central Bank policies and interest rate decreases have triggered and may continue to trigger increases in inflation, and, consequently, growth volatility and the need for sudden and significant interest rate increases, which could negatively affect us and increase our indebtedness.

Currently, fixed broadband and mobile service providers use the internal general price index (Índice Geral de Preços - Disponibilidade Interna), or IGP-DI, to adjust their prices and television and cable service providers use the market general price index (Índice Geral de Preços ao Mercado), or IGP-M.  The IGP-DI and IGP-M are inflation indexes developed by the Fundação Getúlio Vargas, a private organization. Since 2006, telephone fees for fixed line services have been indexed to the telecommunication services index (Índice de Serviços de Telecomunicações), or IST, adjusted by a productivity factor, which is defined by ANATEL Resolution 507/2008. The IST is an index composed of other domestic price indexes (including the IPCA, IGP-DI and IGP-M, among others) that is intended to reflect the telecommunications industry’s operating costs. As a result, this index serves to reduce potential discrepancies between our industry’s revenue and costs, and thus reduce the apparent adverse effects of inflation on our operations. The productivity factor, pursuant to which ANATEL is authorized to adjust fee rates, is calculated based on a compensation index established by ANATEL to incentivize operational efficiency and to share related gains in earnings from fixed line services with customers through fee rate adjustments.  The IST is calculated based on a 12-month period average. This may cause increases in our revenues above or below our costs (including salaries), with potentially adverse impacts on our profitability.

Inflation and government measures to combat inflation, along with speculation about possible future governmental measures, have had and are expected to continue to have significant negative effects on the Brazilian economy, including heightened volatility in the Brazilian securities market. On the other hand, these policies may be incapable of preventing increases in the inflation rate. In the event of an increase in inflation, we may not be able to adjust the prices we charge our customers to offset the effects of inflation on our cost structure, which may adversely affect us.

Fluctuations in exchange rates may adversely affect our ability to meet liabilities denominated or linked to foreign currencies or reduce our income in foreign currency, and may have a material adverse effect on the market value of our preferred shares and ADSs.

The Brazilian currency has been historically volatile and has been devalued frequently over the past three decades. Throughout this period, the Brazilian government has implemented various economic plans and used various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system. Although long-term depreciation of the real is generally linked to the rate of inflation in Brazil, depreciation of the real occurring over shorter periods of time has resulted in significant variations in the exchange rate between the real, the U.S. dollar and other currencies. The exchange rate between the U.S. dollar and the Brazilian real has experienced significant fluctuations in recent years. The real depreciated 14.6% against the U.S. dollar in 2013, 13.4% in 2014 and 47.0% in 2015. In 2016, the real appreciated 16.5% against the U.S. dollar and in 2017, the real depreciated 1.5%. There can be no assurance that the real will not again depreciate against the U.S. dollar or other currencies in the future.

As of December 31, 2017, 2.7% of our total indebtedness of R$8.5 billion was denominated in foreign currency. As of December 31, 2017, we had currency hedges in place to cover all of our financial foreign currency-denominated indebtedness. Approximately 6.4% of our operating costs and expenses are payable or linked to payment by us in U.S. dollars or Euros. By contrast, 99.7% of our revenue is generated in reais, except income derived from hedging transactions, international long-distance interconnection fees and services to customers outside of Brazil.

To the extent that the value of the real decreases relative to the U.S. dollar or the Euro, our commitments payable or linked to payment by us in foreign currencies become more expensive. Although our accounts receivable denominated in foreign currencies would also appreciate, the net effect could adversely affect our revenue and expenses. In addition, the IST does not adequately reflect the true effect of exchange rate fluctuations. Thus, our revenue, when translated to U.S. dollars, does not adequately reflect the true effect of exchange rate fluctuations, which may affect our results of operations.

Nearly all of our transactions denominated in foreign currencies are covered by hedge transactions. Since May 2010, we have been using a “net balance coverage” strategy, pursuant to which we seek to hedge our net foreign exchange exposure arising from invoices issued or received in foreign currencies. Our corporate market risk department periodically reviews our foreign currency invoices and manages our commitments linked to foreign currencies to limit our overall foreign currency exposure. Though we believe this strategy has substantially reduced our exposure to fluctuations in exchange rates, we cannot guarantee that this strategy will be successful. There can be no assurance that we will continue in the future our practice of entering into hedge instruments to hedge against the volatility of the real. Additionally, the liquidity in the derivatives market may become scarce, making it more difficult to hedge our foreign exchange exposure under satisfactory conditions, which could negatively affect our overall financial performance in case of depreciation of the real against such foreign currencies.

Political, economic and social developments and the perception of risk in other developed and emerging countries may adversely affect the Brazilian economy, our business, and the market price of Brazilian securities, including our preferred shares and ADSs.

The market for securities issued by Brazilian companies may be influenced, to varying degrees, by economic conditions in both developing and developed economies. The reaction of investors to developments in other countries may have an adverse impact on the market value of securities of Brazilian companies. The prices of shares traded on the B3, for example, have historically been sensitive to fluctuations in interest rates in the United States, as well as variations of the main U.S. stock exchanges. Additionally, crises in other emerging countries or the economic policies of other countries may reduce investor demand for securities of Brazilian companies, including our preferred shares and ADSs. Any of the foregoing developments may adversely affect the market value of our preferred shares and ADSs and hinder our ability to access the capital markets and finance our operations in the future on acceptable terms and costs, or at all.

To the extent that economic problems in emerging market countries or elsewhere adversely affect Brazil, our business and the market value of our preferred shares and ADSs could be adversely affected. Furthermore, we cannot assure you that, in the event of adverse developments in emerging market economies, the international capital markets will remain open to Brazilian companies or that the resulting interest rates in such markets will be advantageous to us. Decreased foreign investment in Brazil may negatively affect growth and liquidity in the Brazilian economy, which in turn may have a negative impact on our business. Disruption or volatility in the global financial markets could further increase negative effects on the financial and economic environment in Brazil, which could have a material adverse effect on us.

Any further downgrading of Brazil’s credit rating could reduce the trading price of our preferred shares and ADSs.

We may be harmed by investors’ perceptions of risks related to Brazil’s sovereign debt credit rating. Rating agencies regularly evaluate Brazil and its sovereign ratings, which are based on a number of factors including macroeconomic trends, fiscal and budgetary conditions, indebtedness metrics and the perspective of changes in any of these factors.

Brazil has lost its investment grade sovereign debt credit rating by the three main U.S. based credit rating agencies, S&P Global Ratings, Moody’s and Fitch. S&P Global Ratings downgraded Brazil’s sovereign debt credit rating from BBB- to BB+ in September 2015, subsequently reduced it to BB in February 2016 and further reduced it to BB- in January 2018 with a stable outlook. In December 2015, Moody’s placed Brazil’s Baa3 sovereign debt credit rating on review and downgraded Brazil’s sovereign credit rating in February 2016 to Ba2 with a negative outlook, citing the prospect for further deterioration in Brazil’s indebtedness figures amid a recession and challenging political environment. Fitch downgraded Brazil’s sovereign credit rating to BB+ with a negative outlook in December 2015, citing the country’s rapidly expanding budget deficit and worse-than-expected recession, and further downgraded Brazil’s sovereign debt credit rating in May 2016 to BB with a negative outlook.

Brazil’s sovereign credit rating is currently rated below investment grade by the three main credit rating agencies. Consequently, the prices of securities issued by Brazilian companies have been negatively affected. A prolongation or worsening of the current Brazilian recession and continued political uncertainty, among other factors, could lead to further ratings downgrades. Any further downgrade of Brazil’s sovereign credit ratings could heighten investors’ perception of risk and, as a result, cause the market price of our preferred shares and ADSs to decline.

Risks Relating to the Brazilian Telecommunications Industry and Us

Extensive government regulation of the telecommunications industry and our concession agreements may limit, in some cases, our flexibility in responding to market conditions, competition and changes in our cost structure or impact our fees.

Our business is subject to extensive regulation, including any regulatory changes that may occur during the terms of our concession agreements and our authorizations to provide telecommunication services in Brazil. ANATEL, the main telecommunications industry regulator in the country, regulates, among other things:

·industry policies and regulations;

·licensing;

·fees and tariffs;

·competition, including our ability to grow by acquiring other telecommunications businesses;

·service, technical and quality standards;

·interconnection and settlement arrangements; and

·universal service obligations.

The Brazilian telecommunications regulatory framework is continuously evolving. The interpretation and enforcement of regulations, the assessment of compliance with regulations and the flexibility of regulatory authorities are all marked by uncertainty. We operate under authorizations and a concession from the Brazilian government, and our ability to maintain these authorizations and concession is a precondition to our success. However, because of the changing nature of our regulatory framework, we cannot provide assurances that ANATEL will not adversely modify the terms of our authorizations and/or licenses. According to our operating authorizations and licenses, we must meet specific requirements and maintain minimum quality, coverage and service standards. Our failure to comply with such requirements may result in the imposition of fines, penalties and/or other regulatory responses, including the termination of our operating authorizations and concession. Any partial or total termination of any of our operating authorizations and licenses or our concession would have a material adverse effect on our business, financial condition, revenues, results of operations and prospects.

In recent years, ANATEL has been reviewing and introducing regulatory changes, especially regarding asymmetric competition measures and interconnection fees charged among local providers of telecommunications services. Asymmetric competition measures can include regulations intended to rebalance markets in which a market participant has distinct market power over other competitors. The adoption of disproportionately asymmetric measures could have a material adverse effect on our business, financial condition, revenues, results of operations and prospects.

With respect to interconnection fees, these are an important part of our revenue and cost bases. Such fees are charged by telecommunications service providers to each other in order to allow interconnected use of each other’s networks. To the extent that changes to the rules governing interconnection fees reduce the amount of fees we can receive, or our ability to collect such fees, our businesses, financial conditions, revenues, results of operations and prospects could be materially adversely affected.

Therefore, our business, results of operations, revenues and financial conditions could be negatively affected by the actions of the Brazilian authorities, including, in particular, the following:

·the introduction of new or stricter operational and/or service requirements;

·the granting of operating licenses in our areas;

8

·limitations on interconnection fees we may charge to other telecommunications service providers;

·delays in the granting of, or the failure to grant, approvals for rate increases; and

·antitrust limitations imposed by ANATEL and CADE.

Our concession may be terminated by the Brazilian government under certain circumstances.

We operate our fixed line business in the state of São Paulo under a concession granted by the Brazilian government. According to the terms of the concession, we are obligated to meet certain universal service requirements and to maintain minimum quality and service standards. For example, ANATEL requires that we satisfy certain conditions with respect to, among other things, the expansion of our network to provide (i) public pay-phone service for all locations with a population over 100 inhabitants and (ii) private individual telephone service for all locations with a population over 300 inhabitants, as well as several quality of service targets. Our ability to satisfy these and other terms and conditions may be affected by factors beyond our control, and our failure to comply with the requirements of our concession may result in the imposition of fines up to R$50 million per incident and/or other government actions, including the termination of our concession. Any partial or total termination of our concession or authorizations would have a material adverse effect on our financial condition and results of operations.

Furthermore, the concession agreements establish that all assets owned by us, and which are indispensable to the provision of the services described in such agreements, are considered “reversible assets” (bens reversíveis) and are deemed to be part of the concession assets. According to ANATEL’s interpretations of current regulations, reversible assets will be automatically returned to ANATEL’s possession upon expiration of the concession agreements in accordance with regulations in force at the time of such expiration, and would not be available to creditors in the event of insolvency, bankruptcy or similar events.

As of December 31, 2017, the net book value of our reversible assets, calculated in accordance with ANATEL’s  interpretation of current regulations, is estimated at R$8.7 billion. These assets are comprised of switching and transmission equipment, public use terminals, external network equipment, energy equipment and systems and operations support equipment.

Review of our concession agreements and/or the implementation of a new regulatory framework in Brazil could have a materially adverse effect on our operations.

The expiration date of our fixed line concession agreements is December 31, 2025. These agreements contain a provision allowing ANATEL to review the concession agreements every five years, and include revisions to terms and conditions that relate to network expansion, modernization and quality of service targets in response to changes in technology, competition in the marketplace and domestic and international economic conditions.

On June 24, 2014, ANATEL opened a public review and comment period for the revisions of the terms of fixed line concession agreements with respect to the 2016-2020 period. However, when the agency released the new version of the agreements in June 2017, operators disagreed with the inclusion by ANATEL of certain provisions, and decided against executing new agreements with the agency. As a result, the agreements with respect to the 2011-2015 period remain in force.

Changes to our concession agreements or to the current regulatory framework may entail the imposition of new requirements, including obligations to make specific investments and/or capital expenditures. ANATEL may also impose new service targets on us with values that we are not able to predict. The conditions, terms and criteria being considered with respect to any such changes in the regulatory framework are still uncertain, and will only be defined by ANATEL after the approval of a law amending the General Telecommunications Act (Lei Geral de Telecomunicações). Any such changes to laws, rules or regulations could have a material adverse effect on our operations and financial condition.

Telefônica Brasil is exposed to risks in relation to compliance with anti-corruption laws and regulations.

Telefônica Brasil is required to comply with Brazilian anti-corruption laws and regulations, as well as laws and regulations on the same subject in jurisdictions where it has its securities traded. In particular, the Company is subject, in Brazil, to Law nº 12,846/2013 and, in the United States, to the U.S. Foreign Corrupt Practices Act of 1977.

Although we have internal policies and procedures designed to ensure compliance with the aforementioned anti-corruption laws and regulations, there can be no assurance that such policies and procedures will be sufficient or that our employees, directors, officers, partners, agents and service providers will not take actions in violation of our policies and procedures (or otherwise in violation of the relevant anti-corruption laws and regulations) for which we or they may be ultimately held responsible. Violations of anti-corruption laws and regulations could lead to financial penalties, damage to our reputation or other legal consequences that could have a material adverse effect on our business, results of operations and financial condition.

In connection with the above-mentioned policies, Telefônica Brasil is currently conducting an internal investigation - which is part of a broader investigation being conducted by the controlling shareholder of the Company (Telefónica, S.A.) - regarding possible violations of the abovementioned laws and regulations. Telefônica Brasil is in contact with governmental authorities about this matter and intends to cooperate with those authorities as the investigation continues. It is not possible at this time to predict the scope or duration of this matter or its likely outcome.

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

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

Our future success also depends on our ability to identify, attract, hire, train, retain and motivate highly skilled technical, managerial, sales and marketing personnel. Competition for such personnel is intense, and we cannot guarantee that we will successfully attract, assimilate or retain a sufficient number of qualified personnel. Failure to retain and attract the necessary technical, managerial, sales and marketing and administrative personnel could adversely affect our business, financial condition and results of operations.

We depend on key suppliers to obtain necessary equipment and services for our business.

We depend on certain key suppliers of equipment and services, especially telecommunications network equipment and handsets, for the execution and development of our business. These suppliers may delay delivery, alter prices and limit supply as a result of problems related to their own businesses, over which we have no control.  If these suppliers are not able to deliver equipment and services regularly, we may face problems with the continuity of our business activities, which may have an adverse effect on our business and results of operations.

We are subject to liabilities relating to third party contractors, which may have a material adverse effect on our business and results of operations.

We are exposed to contingent liabilities resulting from our contracting structure, which includes third party service providers. Such potential liabilities may involve labor claims by third party providers that are treated as direct employees as well as joint liability claims relating to wage or overtime pay complaints and workplace injury claims. If a significant portion of these contingent liabilities are decided against us and for which we have not made adequate provisions, our financial condition and results of operation may be adversely affected.

10

Furthermore, if the contracting of third party service are considered to involve the main activities of the company, it may be characterized as a direct employment, which would significantly increase our costs and as a result we may be subject to administrative proceedings by the relevant labor regulators and may be required to pay fines to the third party service providers.

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

The high growth in data markets in general and broadband in particular may result in a limited supply of equipment essential for the provision of such services, such as data transmission equipment and modems. The restrictions on the number of manufacturers imposed by the Brazilian government for certain inputs, mainly data transmission equipment and modems, and the geographical locations of non-Brazilian manufacturers of these inputs, pose certain risks, including:

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

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

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

If any of these risks materialize, they may result in our inability to provide services to our customers in a timely manner or may affect the prices of our services, which may have an adverse effect on our business, financial condition and results of operations.

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

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

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

Consolidation in the telecommunications market may increase competition in the near future and may change Brazilian market dynamics.

Mergers and acquisitions may change market dynamics, create competitive pressures, force small competitors to find partners and impact our financial condition; and may require us to adjust our operations, marketing strategies (including promotions), and product portfolio.

The entry of a new market participant with significant financial resources or potential changes in strategy by existing telecommunications service providers can change the competitive environment in the Brazilian market. We may be unable to keep pace with these changes, which could affect our ability to compete effectively and have a material adverse effect on our business, financial condition and results of operations.

Additional joint ventures, mergers and acquisitions among telecommunications service providers are possible in the future. If such consolidation occurs, it may result in increased competition within our market. We may be unable to adequately respond to pricing pressures resulting from consolidation in our market, adversely affecting our business, financial condition and results of operations. We may also consider engaging in merger or acquisition activity in response to changes in the competitive environment, which could divert resources away from other aspects of our business.

11

We face significant competition in the Brazilian market.

In 2017, competition in the Brazilian telecommunications sector remained fierce, with operators focusing on improving their base of accesses by attracting customers to higher-value products to increase overall ARPUs and profitability.

In turn, customers are demanding higher quality and more data availability, which require investments in development, modernization, expansion and continuous improvement in service quality and customers’ experience, pressing companies’ results.

As a result, we have faced significant competition, mainly driven by the following factors: (1) commercial and pricing pressures from new mobile portfolios launched by competitors; (2) competitors increasing 3G and 4G coverage, improving the quality of service provided by them; and (3) low-cost alternative services, such as voice and text services provided over IP and Video on Demand, may affect our competitive position in the market.

We continuously monitor the market progress in order to anticipate future challenges and opportunities and how to address them. Nevertheless, our operational results, market position, competitiveness in the market and margins may be negatively affected if we are unable to keep the same pace as our competitors.

Our results of operations may be negatively affected by the application of the Fixed Commuted Telephone Service (Serviço de Telefonia Fixa Comutada), or STFC, rules relating to fixed telephone service and the Personal Mobile Service (Serviço Móvel Pessoal), or SMP, rules relating to mobile services.

We receive payments for the termination of calls in our fixed network. On May 18, 2014, ANATEL established a gradual decrease in termination rates for the STFC concessionaries, including TU-RL (Urban Usage Rate), TU-RIU1 (Interurban Usage Rate Level 1) and TU-RU2 (Interurban Usage Rate Level 2). In the same year, ANATEL also established gradual decreases in mobile interconnection fees, also known as mobile termination rates, or MTR, based on a cost model. The related rates established by ANATEL are set forth in the following table:

	2015	2016	2017	2018	2019
Sector 31 (fixed)
TU-RL	N/A	0.01139	0.00574	0.00289	0.00146
TU-RU1	N/A	0.05339	0.02191	0.00899	0.00369
TU-RU2	N/A	0.06129	0.02348	0.009	0.00345
Mobile
Region I	0.16751	0.09317	0.04928	0.02606	0.01379
Region II	0.16237	0.10309	0.05387	0.02815	0.01471
Region III	0.14776	0.11218	0.06816	0.04141	0.02517

We cannot assure you that new mobile service plans will not be suspended by ANATEL, that the mobile interconnection fees we negotiated will not be changed, nor that future negotiations regarding mobile termination rates will be as favorable as those that were previously set by the agency. If the readjustments to mobile interconnection fees that we negotiated are cancelled or if negotiated mobile interconnection fees in the future are less favorable to us, our business, financial condition, revenues, results of operations and prospects may be adversely affected.

12

ANATEL has the authority to issue new regulations affecting many of our areas of operations.

ANATEL has the authority to issue new regulations affecting many of our areas of operations. Such new regulations could have an adverse effect on our operating results because: (1) ANATEL could significantly reduce the interconnection fees we are able to charge, thereby reducing our revenues (see “—Our results of operations may be negatively affected by the application of the Personal Mobile Service (Serviço Móvel Pessoal – SMP) rules relating to mobile services”); (2) ANATEL may allow more favorable conditions for economic groups without significant market power; (3) the granting of new licenses may increase competition in our area from other operators, which could adversely affect our prices and/or market share, thereby reducing our revenues; (4) ANATEL may require that revenue received for the usage of the SMP network must be included in the calculation of operating revenue, which will increase the cost of renewing licenses; and (5) ANATEL’s general plan of updating the regulations targets several areas of vital importance for the mobile business, such as regulations (i) to improve the quality of services, which may cause an increase in operating costs, (ii) of virtual mobile operations, or MVNO, which may cause an increase in competitive pressure, (iii) against SMP providers exercising market power to negotiate lower mobile termination rate fees, which could cause a decrease in our revenues from the mobile termination rate fees we are able to charge to SMP providers, and (iv) relating to multimedia communication.

For a detailed description of the regulations issued by ANATEL and their impact on our business, see “—Item 4. Information on the Company—Business Overview—Regulation of the Brazilian Telecommunications Industry.”

The industry in which we conduct our business is continually changing and evolving technologically, which demands adequate changes in the regulatory environment.

The telecommunications industry is subject to rapid and significant technological changes. Our future success depends on our ability to anticipate and adapt in a timely manner to technological changes. We expect that new products and technologies will emerge and that existing products and technologies will be further developed.

The advent of new products and technologies could have a variety of consequences. These new products and technologies may reduce the price of our services by providing lower-cost alternatives and the creation of new digital services, such as the example of over-the-top (OTT) players that provide voice and messages over IP. Also, new product and technologies may become superior to, and render obsolete, the products and services we offer and the technologies we use, thus requiring our constant investment in new technology and innovation.

Such new technologies will demand changes in the regulatory environment, challenging both governmental agencies and telecommunication companies. Companies that provide OTT services, which have characteristics similar to telecommunications services, are currently not subject to the same rules as the telecommunications operators. This gap can bring additional challenges to the telecommunications industry, as current developments in the regulatory framework for OTTs are inconsistent and still unclear.

We are subject to certain risks related to conditions and obligations imposed by ANATEL for the use of the spectrum needed for the LTE services we offer.

In 2012, Telefonica acquired 40MHz on the 2.5GHz to 2.69GHz frequencies for the amount of R$ 1.05 billion. In order to meet the coverage requirements we had the obligation of implementing 4G coverage in 1,094 cities by December 31, 2017. By that date, we had made 4G services available in 2,600 municipalities. To achieve these targets, Telefonica has deployed and continues to deploy 4G coverage by serving its customers through the use of its own network or by established agreements of RAN-sharing approved by ANATEL. The remaining coverage commitments in cities with less than 30,000 inhabitants may be fulfilled with other frequency bands, according to the following schedule:

·by December 31, 2018: 117 cities; and

·by December 31, 2019: 156 more cities.

13

To complete the 450 MHz frequency requirements we had the obligation to meet voice and data demand in remote rural areas. As a commitment, we are required to provide infrastructure and service in rural areas in the states of Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe, and in the countryside of São Paulo, for a total of 2,556 municipalities.

Regarding the 700MHz spectrum, ANATEL has allocated the band for the provision of fixed, mobile and broadband services. On September 30, 2014 we acquired 20 MHz (10+10 MHz) with nationwide coverage, for R$1.92 billion, at the minimum price, plus R$904 million for the band cleaning (migration of broadcasters that currently occupy the band and interference management). According to the auction rules, the winning bidders are responsible for financing and managing the band cleaning process.

In January 2016, the Ministry of Communications (presently, the Ministry of Science, Technology, Innovation and Communications) published a new schedule for the analog TV Switch Off, postponing the usage of the 700 MHz frequency for telecommunications in some major Brazilian cities. According to the schedule and further revisions, 11 cities had its analog TV services turned off in 2016, including Rio Verde (GO) and Brasília (DF). In 2017 the switch off was completed in over 404 cities. In 2018 the analog switch off is expected to be completed in 1124 cities distributed in 24 states. The switch off for the remaining 4244 cities is set for 2023, though the activation of LTE in these cities does not require the switch off schedule to be completed.

In December 2015, ANATEL auctioned the remaining spectrum lots in the 1800 MHz, 1900 MHz and 2500 MHz bands. Telefônica acquired seven lots of 2.5 GHz frequency band for a total of R$185.4 million. These lots are associated to five capital cities located in the States of São Paulo, Rio de Janeiro, Porto Alegre, Florianópolis, and Palmas and one countryside city in the State of Mato Grosso do Sul. Such frequencies are already being used for the provision of mobile broadband service on 4G.

The targets established by ANATEL for the fast-paced implementation of networks could be impacted by (1) our ability to obtain licenses for the construction of new sites at the speed necessary to achieve the coverage targets, (2) the capacity of our suppliers to deliver the equipment necessary for this expansion, which may increase the price of such equipment, and (3) lack of qualified resources to meet the expected implementation pace.

If we are not able to meet targets and obligations set forth in the bid documents, ANATEL may use our bank guarantees, we may be subject to fines and/or have our licenses to operate these frequencies revoked, negatively affecting our business and results of operations. Additionally, the inefficient use of any frequency may lead to the loss of the usage license.

Our sales could be suspended as a result of issues with the quality of our services.

ANATEL and other judiciary and administrative agencies have the authority to suspend our sales in an attempt to improve the overall quality of telecommunications services. Sales suspensions are generally applied to the services for which there have been complaints by consumers and the consumer protection agencies. When applied, the suspension is temporary and usually lifted once the company presents an action plan for improvement. In July 2012, ANATEL suspended mobile service sales from three of our main competitors, Oi, Claro and Tim, as result of a considerable increase in consumer complaints. The suspensions lasted about 20 days and ANATEL requested that all telecommunications companies, including us, present an action and investment plan to improve the mobile network. Although our action plan was approved by ANATEL in September 2012, if a similar increase in customer complaints occurs in the future we may face suspension of one or more of our services until a new plan can be presented to and approved by ANATEL, which may materially affect our business and results of operations.

Internet regulation in Brazil is recent and still limited and several legal issues related to the Internet are uncertain. 

In 2014, Brazil enacted a law, which we refer to as the Civil Rights Framework for the Internet, setting forth principles, guarantees, rights and duties for the use of the internet in Brazil, including provisions about internet service provider liability, internet user privacy and network neutrality. In May 2016, further regulations were passed relating to the privacy and network provisions set forth in Civil Rights Framework for the Internet. However, unlike in the United States, few legal precedents relating to the Internet Act exist and existing jurisprudence has not been consistent, especially with respect to the application of the network neutrality principle. Legal uncertainty arising from the limited guidance provided by current laws in force allows for different judges or courts to decide very similar claims in different ways and establish contradictory jurisprudence. This legal uncertainty allows for rulings against us and could set adverse precedents, which individually or in the aggregate could seriously harm our business, results of operations and financial condition. In addition, legal uncertainty may harm our customers’ perception and use of our service.

14

Certain of our debt agreements contain financial covenants, and any default under such debt agreements may have a material adverse effect on our financial condition and cash flows.

Certain of our existing debt agreements contain restrictions and covenants and require the maintenance or satisfaction of specified financial ratios and tests. Failure to meet or satisfy any of these covenants, financial ratios or financial tests could result in an event of default under these agreements.

We are subject to environmental laws and regulations. Failure to comply with governmental laws and regulations could subject us to penalties that could have an adverse effect on our business.

Our operations and properties are subject to a variety of environmental laws and regulations governing, among other things, environmental licensing and registries, protection of flora and fauna, air emissions, waste management and remediation of contaminated areas, among others. Our failure to comply with present and future requirements, or the management of existing and identification of new contamination, could cause us to incur substantial costs, including cleanup costs, indemnification, compensation, fines, suspension of activities and other penalties, investments to upgrade our facilities or change our processes, or curtailment of operations. The identification of presently unidentified environmental conditions, more vigorous enforcement by regulatory agencies, enactment of more stringent laws and regulations or other unanticipated events may arise in the future and give rise to material environmental liabilities and related costs. The occurrence of any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.

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

Currently, there are approximately 250 municipal laws in Brazil that limit the installation of new antennas for mobile service. This scenario has been a barrier to the expansion of mobile networks. Those laws are meant to regulate issues related to zoning and the alleged effects of the radiation and radiofrequencies of the antennas. Despite the existence of a federal law approved in 2015, that addresses this issue by establishing new guidelines to create a consolidated plan for the installation of antennas, as long as the municipal laws remain unchanged, the risk of noncompliance with regulations and of having services of limited quality in certain areas continues to exist.

Additional antenna installation is also limited as a result of concerns that radio frequency emissions from base stations may cause health problems and other environmental impacts. These concerns could have an adverse effect on the wireless communications industry and, possibly, expose wireless providers, including us, to litigation. Based on information from the World Health Organization (WHO) we are not aware of any evidence in the latest medical research that conclusively establishes any relationship between radio frequency emissions of base stations and health concerns. Perceived risks may, however, delay expansion of our network if we experience problems in finding new sites, which in turn may delay expansion and affect the quality of our services.

For instance, in May 2009, the Brazilian government published Law No. 11934/2009 that limits the exposure for fields with frequencies up to 300 GHz. The new law uses the exposure limits determined by the International Commission on Non-Ionizing Radiation Protection and recommended by the WHO and restricts the installation of new antennas.

New laws may create additional transmission regulations, which in turn, could have an adverse effect on our business. Health concerns regarding the effects of radio frequency emissions may also discourage the use of mobile telephones and may result in the adoption of new measures by governments or any other regulatory interventions, any of which could materially and adversely affect our business, results of operations and financial condition.

15

We face risks associated with litigation.

We are party to a number of lawsuits and other proceedings. An adverse outcome in, or any settlement of, these or other lawsuits could result in significant costs to us. In addition, our senior management may be required to devote substantial time to these lawsuits, which they could otherwise devote to our business. See “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings.”

Risks Relating to the Preferred Shares and the ADSs

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 our executive officers and our independent public accountants reside or are based in Brazil. Also, six of our twelve directors reside or are based in Brazil. Substantially all of our assets and those of these other persons are located in Brazil. As a result, it may not be possible for holders of the 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. 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 due to actions by us, our directors or executive officers than would shareholders of a U.S. corporation.

Holders of our preferred shares and ADSs generally do not have voting rights.

In accordance with Brazilian Corporate Law and our bylaws, holders of our preferred shares, and therefore of our ADSs, are not entitled to vote at meetings of our shareholders, except in limited circumstances set forth in “Item 10. Additional Information—B. Memorandum and Articles of Association.”

Holders of our preferred shares might be unable to exercise preemptive rights with respect to the preferred shares unless there is a current registration statement in effect which covers those rights or unless an exemption from registration applies.

Holders of our preferred shares will not be able to exercise the preemptive rights relating to the preferred shares underlying their ADSs unless a registration statement under the U.S. Securities Act of 1933, as amended, or the Securities Act, is effective with respect to the shares underlying those rights, or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement. Unless we file a registration statement or an exemption from registration applies, holders of our preferred shares may receive only the net proceeds from the sale of their preemptive rights by the depositary, or if the preemptive rights cannot be sold, they will lapse and they will not receive any value for them. For more information on the exercise of these rights, see “Item 10. Additional Information—B. Memorandum and Articles of Association—Description of our Bylaws—Preemptive Rights.”

An exchange of ADSs for preferred shares risks the loss of certain foreign currency remittance and Brazilian tax advantages.

Beginning on March 30, 2015, the different forms of foreign portfolio investments in Brazil, including investments via Depositary Receipts, have been regulated by CMN Resolution 4,373, of September 29, 2014 (or “Resolution No. 4,373”), which revoked the former rule (CMN Resolution 2,689, of January 26, 2000) that had been in effect for the previous 15 years. Resolution No. 4,373 provides for the issuance of Depositary Receipts in foreign markets in respect of shares of Brazilian issuers, and, pursuant to this regulation, the ADSs benefit from the certificate of foreign capital registration, which permits Citibank N.A., as depositary, to convert dividends and other distributions with respect to preferred shares into foreign currency, and to remit the proceeds abroad. Holders of ADSs who exchange their ADSs for preferred shares will then be entitled to rely on the depositary’s certificate of foreign capital registration for five business days from the date of exchange. Thereafter, they will not be able to remit non-Brazilian currency abroad unless they obtain their own certificate of foreign capital registration, or unless they qualify under CMN Resolution No. 4,373, which entitles certain investors to buy and sell shares on Brazilian stock exchanges without obtaining separate certificates of registration. CMN Resolution No. 4,373 replaced both CMN Resolution No. 1,927 and CMN Resolution No. 2,689 as of March 30, 2015. Further rules will be issued by CVM and by the Central Bank to regulate foreign investments in ADSs, including with regard to the exchange of ADSs for preferred shares and the remittance of funds arising from the sale of these preferred shares.

16

If holders of ADSs do not qualify under Resolution No. 4,373, they will generally be subject to less favorable tax treatment with respect to our preferred shares. There can be no assurance that the depositary’s certificate of registration or any certificate of foreign capital registration obtained by holders of ADSs will not be affected by future legislative or regulatory changes, or that additional Brazilian law restrictions applicable to their investment in the ADSs may not be imposed in the future.

Holders of our preferred shares will be subject to, and holders of our ADSs could be subject to, Brazilian income tax on capital gains from sales of preferred shares or ADSs.

Brazilian Law No. 10,833 provides that gains on the disposition of assets located in Brazil by nonresidents of Brazil, whether to other nonresidents or to Brazilian residents, will be subject to Brazilian taxation. The preferred shares are expected to be treated as assets located in Brazil for purposes of the law, and gains on the disposition of preferred shares, even by nonresidents of Brazil, are expected to be subject to Brazilian taxation.

Based on the fact that the ADSs are issued and registered abroad, we believe that gains on the disposition of ADSs made outside of Brazil by nonresidents of Brazil to another non-Brazilian resident would not be subject to Brazilian taxation, since they would not fall within the definition of assets located in Brazil for purposes of Law 10,833. However, considering the general and unclear scope of Law No. 10,833 and the absence of judicial/administrative court rulings in respect thereto, we cannot be assured that such an interpretation of this law will prevail in the courts of Brazil.

In case of any assessment by the Brazilian tax authorities, the gains arising from the disposal of ADSs made as of January 1, 2017 could be subject to capital gain tax in Brazil at (i) progressive rates ranging from 15% to 22.5% (for transactions executed after January 1, 2017) or at a flat rate of 15% (for transactions executed before January 1, 2017), or (ii) 25% if the non-Brazilian holder is located in a tax haven jurisdiction, whether the transaction was executed before or after January 1, 2017. See “Item 10. Additional Information—E. Taxation—Brazilian Tax Considerations.”

Certain Factors Relating to Our Controlling Shareholder

Our controlling shareholder has power over the direction of our business.

Telefónica S.A., or Telefónica, our controlling shareholder, and its affiliates currently own directly and indirectly approximately 94.47% of our voting shares and 73.58 % of our total capital stock. See “Item 7. Major Shareholders and Related Party Transactions—A. Major Shareholders” and “Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions.” As a result of its share ownership, Telefónica has the power to control us and our subsidiaries, including the power to elect our directors and officers and to determine the outcome of any action requiring shareholder approval, including corporate reorganizations and the timing and payment of our dividends. Given this degree of control over our company, circumstances could arise under which the interests of Telefónica could be deemed to be in conflict with the interests of our other shareholders.

ITEM 4.        INFORMATION ON THE COMPANY

A.    History and Development of the Company

General

We were incorporated on May 22, 1998, as a corporation (sociedade anônima) organized under the laws of the Federative Republic of Brazil, as a result of the restructuring and privatization of Telecomunicações Brasileiras S.A. and its operating subsidiaries, or the Telebrás System, which monopolized the provision of public telecommunications services in virtually all areas of Brazil prior to 1998. We were incorporated under the name Telesp Participações S.A. and after subsequent reorganizations we were named Telecomunicações de São Paulo S.A. – TELESP. After our merger with Vivo Participações in October 2011, we changed our corporate name to Telefônica Brasil S.A.

On September 18, 2014, we entered into a stock purchase agreement with Vivendi S.A. to acquire all of the shares of GVT Participações S.A., or GVT, the controlling shareholder of Global Village Telecom S.A., or Operating GVT, which was approved by our board of directors on the same date.

According to Brazilian Law, the transaction must be approved by both ANATEL and CADE. On December 22, 2014, ANATEL approved the transaction and imposed certain obligations, that include (1) the maintenance of current GVT services and plans within the same geographic scope in which GVT previously operated, requiring, in addition, that the successor company expand its operations to at least ten new municipalities within three years beginning on January 26, 2015; and (2) the waiver of the STFC license held by GVT within 18 months of ANATEL’s decisions, since the same economic group cannot hold more than one STFC license in the same geographic area. Telefônica has satisfied both obligations.

On March 25, 2015, CADE provisionally approved the GVT acquisition, subject to a series of obligations imposed to prevent any undesired concentration effects of the merger. Such obligations require that we:

·Maintain, for at least three years, the current geographical coverage for STFC, SCM and SeAC services;

·Maintain, for at least three years, the current average broadband speed for GVT’s customers on a nationwide basis. The reference as of December, 2014 is 15.1 Mbps;

·Maintain, for at least three years, the current average broadband speed for GVT’s customers in São Paulo. The reference as of December, 2014 is 18.25 Mbps; and

·Do not exchange, directly or indirectly, classified information, strategic or competitively sensitive information with any other company or between management and representative responsible for subsidiaries of Vivendi Group, Telefónica Group and Telecom Italia Group related to its operations in the Brazilian market.

In November 2015, ANATEL consented to our corporate reorganization involving Telefônica Brasil S.A., GVT Participações S.A. and its subsidiaries. The approval was subject to certain conditions such as the end of overlap licenses of STFC, SCM and SeAC within 18 months and the obligation to present a list of all assets from the companies incorporated in our STFC (Sector 31, Region III) concession area, confirming the absence of reversible assets burdened judicially (by means of a negative certificate), or in case of attachment, present the appropriate requests for replacement.

On March 14, 2016, the corporate reorganization was approved by our Board of Directors, and was completed on April 1, 2016, after the approval by an extraordinary shareholders meeting of the relevant companies.

On July 3, 2017, Telefônica Data S.A., a wholly owned subsidiary of the Company, acquired all the shares of capital stock of Terra Networks Brasil S.A. from SP Telecomunicações Participações S.A., one of the controlling shareholders of the Company. The purpose of the Terra Networks Transaction is to expand and integrate our offering of digital services, in order to provide additional value to our customer base and TData’s.

18

We are registered with the CVM as a publicly held company and our stock is traded on the B3 – Brasil, Bolsa, Balcão under the symbol “VIVT3” (formerly “TLPP3”) for common shares and “VIVT4” (formerly “TLPP4”) for preferred shares. We are also registered with the SEC in the United States and our ADSs are traded on the NYSE, under the symbol “VIV” (formerly “TSP”). Our headquarters are located at Avenida Engenheiro Luis Carlos Berrini, 1376, 04571-936, São Paulo, SP, Brazil. Our telephone number is 55-11-3430-3687 and our website is www.telefonica.com.br/ir. The information on our website is not part of this annual report on Form 20-F.

As of December 31, 2017, we had 569,354,053 outstanding common shares (excluding treasury shares), with no par value per share, and 1,119,339,723 outstanding preferred shares (excluding treasury shares), with no par value per share. Our shareholders’ equity amounted to R$69.5billion as presented in our audited financial statements prepared in accordance with IFRS.

Historical Background

Corporate Restructuring Involving Telefônica Brasil and Vivo Participações

On July 28, 2010, our controlling shareholder, Telefónica, reached an initial agreement with Portugal Telecom for the acquisition of 50% of the capital stock of Brasilcel, N.V., or Brasilcel. As a result of this transaction, Telefónica held 100% of the capital stock of Brasilcel. At that time, Brasilcel held approximately 60% of the capital stock of Vivo Participações. On December 21, 2010, Brasilcel was merged into Telefónica.

Due to the acquisition of control of Vivo Participações, on February 16, 2011, Telefónica, through its subsidiary SP Telecomunicações Ltda., or SP Telecom, launched a public tender offer for the common shares of Vivo Participações (the only shares with voting rights) held by minority shareholders. As a result of the public tender offer, on March 18, 2011, SPTelecom acquired 10,634,722 common shares of Vivo Participações, representing 2.66% of its shares, resulting in the Telefónica group’s ownership of 62.1% of Vivo Participações.

On December 27, 2010, the boards of directors of Vivo Participações and Telefônica Brasil approved the terms and conditions of a corporate restructuring, which provided for the merger of shares issued by Vivo Participações into Telefônica Brasil. The corporate restructuring was approved by ANATEL on March 24, 2011, and on April 27, 2011, the shareholders of Vivo Participações and Telefônica Brasil approved the merger of shares issued by Vivo Participações into Telefônica. On June 14, 2011, the board of directors of both companies approved a second corporate restructuring, pursuant to which Vivo Participações became our wholly owned subsidiary. The terms and conditions of the second corporate restructuring were approved unanimously by the shareholders of both companies on October 3, 2011. Vivo Participações was merged into us, and the holders of the merged shares of Vivo Participações received new shares in the company.

Due to the merger of Vivo Participações into us, our capital was increased by R$31.2 billion, reflecting the economic value of the shares issued as a result of the merger. The merger did not change the identity of the controlling shareholders of the companies.

Additionally, as a consequence of this merger, on July 6, 2011, Vivo Participações filed a statement with the SEC in order to cancel the registration of its American Depositary Shares, or ADS, program since all of its ADSs were converted into ADSs of Telefônica Brasil. The SEC approved the deregistration on July 7, 2011.

A third stage of the corporate restructuring was approved by ANATEL on August 16, 2011. On October 3, 2011, our shareholders approved the merger of Vivo Participações into us and Telefônica Brasil absorbed Vivo Participações’ equity, extinguishing Vivo Participações, which further simplified and rationalized our cost structures. On the same date, we changed our name from Telecomunicações de São Paulo S.A. – TELESP to Telefônica Brasil S.A., to reflect our nationwide operations. On October 18, 2011, ANATEL approved transfer of the authorization for the provision of SMP services in the state of Minas Gerais from Vivo Participações to Vivo.

As a result of this name change, the ticker symbols for our shares were also changed as of October 6, 2011 (inclusive), from TLPP3, for the common shares, and TLPP4, for the preferred shares, to VIVT3 and VIVT4, respectively, with the subsequent change of our trading name to TELEF BRAZIL. Our ticker symbol for the ADRs on the NYSE was changed to VIV, from TSP.

Telefónica and Telecom Italia Agreement

Through a series of transactions from 2007 to 2009, Telefónica acquired an indirect holding in the voting shares of Telecom Italia through its holdings in the Italian company TELCO S.p.A. Telecom Italia holds an indirect interest in TIM Participações S.A., or TIM, a Brazilian telecommunications company. None of Telefónica, Telefônica Brasil or any other affiliate of Telefónica was involved with or had decision-making powers over TIM’s operations in Brazil, although Telefónica held an indirect interest with respect to TIM’s operations in Brazil. They were also legally and contractually forbidden from exercising any voting rights in TIM’s operations in Brazil.

On June 16, 2014, TELCO, S.p.A.’s Italian shareholders exercised their right to a spin-off, in accordance with the shareholders’ agreement. The implementation of the spin-off was approved by the shareholders on July 9, 2014 and was subject to approval from ANATEL and CADE. When approved by ANATEL and CADE, the spin-off consisted of the shares held by Telecom Italia being spun-off to four new companies, each of which would be wholly owned by one of TELCO, S.p.A.’s shareholders and each of which would hold shares of Telecom Italia, S.p.A. proportional to their holding in TELCO, S.p.A.

As a result of the spin-off, Telefónica S.A. would indirectly hold 14.77% of Telecom Italia S.p.A. of which 8.3% would be exchanged with Vivendi as consideration in the GVT acquisition and 6.47% would be tied to debentures issued by Telefónica S.A. in July 2014 convertible into shares of Telecom Italia upon maturity.

On December 22, 2014, ANATEL authorized the spin-off of TELCO, S.p.A. conditional on the suspension of all control rights of Telefónica S.A. in Telecom Italia, S.p.A. and its subsidiaries. In addition, ANATEL authorized the GVT acquisition, subject to certain regulatory obligations. On March 25, 2015, CADE approved the spin-off of TELCO S.p.A. and the GVT acquisition, subject to certain regulatory obligations.

On April 7, 2015, ANATEL approved the swap transaction to exchange 12% of our common shares and 0.7% of our preferred shares owned by Vivendi for 8.3% Telecom Italia’s common shares with voting rights, previously held by Telefónica, S.A..

On July 29, 2015, Telefónica, S.A. entered into an agreement with Vivendi, S.A. through which Telefónica, S.A. committed to transfer its treasury shares representing approximately 0.95% of its capital stock in exchange for Telefônica Brasil S.A. preferred shares (received by Vivendi, S.A. in the GVT acquisition) representing approximately 3.5% of our capital stock. Pursuant to this agreement, Vivendi, S.A. has committed to, among other obligations: (i) refrain from selling the Telefónica shares during specified periods (lock up), and (ii) comply with certain restrictions that, in case of sale, and once the lock up periods have lapsed, would ensure an orderly sale of such shares.

On July 30, 2015, Vivendi S.A. announced after the closing of the New York Stock Exchange trading session of July 30, 2015, that they sold 67.9 million preferred shares of Telefônica Brasil S.A. (representing 4.0% of our capital stock).

As a result, Telefónica no longer held, directly or indirectly, any economic interest in Telecom Italia by the end of 2015.

Restructuring Involving the Subsidiaries of Telefônica Brasil

On March 15, 2012, our board of directors approved a corporate restructuring of our wholly owned subsidiaries to align the services provided by each such subsidiary and to concentrate all telecommunication services in one company. The restructuring was finalized on July 1, 2013.

The restructuring was implemented by means of a spin-off and mergers involving only our wholly owned subsidiaries, A. TELECOM S.A., or A. TELECOM, Telefonica Data S.A., or TData, Telefônica Sistema de Televisão S.A. and Vivo. The mergers did not result in an increase in our capital stock or in the issuance of new shares by us, and the corporate restructuring did not give rise to a change in the equity interests held by our shareholders. As a result of the restructuring, value added services and innovative services provided by several wholly owned subsidiaries of the company were consolidated under TData and other telecommunications services were consolidated under Telefônica Brasil, which, as a final step to the corporate restructuring, merged these subsidiaries.

20

Since the completion of the merger, all services which are exclusively telecommunications services have been provided by us, Telefônica Brasil. Other services, including value added services, have been performed by our wholly owned subsidiary, TData. We were required to separate our services into separate companies because the telecommunications laws in Brazil and our concession agreement require that we only perform telecommunications services. ANATEL approved the corporate restructuring in May 2013.

Acquisition of GVT

On September 18, 2014, we entered into a stock purchase agreement with Vivendi and certain of its controlled companies, or collectively, Vivendi, and with GVTPar, Telefónica, S.A. and Operating GVT, pursuant to which we agreed to purchase all of the shares of GVTPar, the controlling shareholder of Operating GVT. This acquisition was approved by our board of directors on September 18, 2014.

As consideration for the acquisition, we agreed to pay a portion of the price in cash and a portion in kind, in the form of our common and preferred shares, as follows: (1) €4,663,000,000 to be paid in cash on the closing date, as adjusted pursuant to the stock purchase agreement, and (2) our common and preferred shares amounting to 12% of our total share capital following the capital increase contemplated in the stock purchase agreement and the merger of shares of GVTPar, which must be in the same proportion as our existing common shares and preferred shares. The total consideration was paid after the conclusion of (A) a capital increase, the proceeds of which were used to pay the cash consideration described in (1) above, and (B) the merger of shares of GVTPar into us.

On December 22, 2014, ANATEL approved the transaction and imposed certain obligations, which include (1) the maintenance of current GVT services and plans within the same geographic scope in which GVT operates today, requiring, in addition, that the successor company expand its operations to at least ten new municipalities within three years beginning on January 26, 2015; and (2) the waiver of the FSTS license held by GVT within 18 months of ANATEL’s decisions, because regulations establish that the same economic group cannot hold more than one FSTS license in the same geographic area. We understand that obligations imposed do not compromise the terms of the GVT acquisition or its value.

On March, 25 2015, CADE’s administrative tribunal approved the transaction on the basis of certain confidential commitments offered by us and Vivendi S.A. The commitments include the execution of two merger control agreements: the first between CADE and us and the second between CADE and Vivendi S.A.

On March 25, 2015, our board of directors approved the public offering of shares, including shares in the form of ADSs, pursuant to a capital increase in the amount of R$15,812,000,038.03, through issuance of 121,711,240 common shares, at a price of R$38.47 and 236,803,588 preferred shares, at a price of R$47.00 as well as an additional 6,282,660 preferred shares pursuant to the exercise of the over-allotment option.

On May 28, 2015, our shareholders approved the ratification of the Stock Purchase Agreement and Other Covenants, entered into by the Company, as Buyer, and Vivendi S.A. and its subsidiaries, Société d’Investissements et de Gestion 108 SAS and Société d’Investissements et de Gestion 72 S.A., as Sellers, whereby all the shares issued by GVTPar, the controlling shareholder of Global Village Telecom S.A., were acquired by us.

Therefore, as provided for in the stock purchase agreement, we paid a portion of the GVT acquisition price in cash, receiving shares of GVTPar and GVT Operator, and another portion in shares, to FrHolding108 as a result of the merger of GVTPar’s shares into us, representing 12% of our capital stock after the merger.

21

After the merger and as a result of the acquisition, our corporate structure was as follows:

On June 24, 2015, the transaction for the exchange of shares between Telefónica and Société d’Investissements et de Gestion 108 SAS, a company controlled by Vivendi S.A. was completed, through which FrHolding108 transferred to Telefónica 76,656,559 shares representing 4.5% of our capital stock, including 68,597,306 common shares representing 12% of such class of shares and 8,059,253 preferred shares representing 0.72% such class of shares, in exchange for 1,110,000,000 shares representing 8.2% of the common shares of Telecom Italia, S.p.A., previously held by Telco TE, S.p.A., a subsidiary of Telefónica.

On July 29, 2015, Vivendi S.A. sold 67.9 million preferred shares, representing 4% of our capital stock. On the same day, Telefónica S.A. announced that it entered into an agreement with Vivendi’s subsidiary Société d’Investissements et de Gestion 108 SAS, through which Telefónica committed to deliver 46.0 million of its treasury shares, representing 0.95% of its share capital, in exchange for 58.4 million preferred shares of Telefonica Brasil, S.A., (received by Société d’Investissements et de Gestion 108 SAS. in the context of the acquisition of GVT Participaçoes, S.A.). On September 16, 2015, the exchange of shares was concluded. Consequently, Telefónica S.A.’s interest in the Company was increased by 5.2% in relation to the total preferred shares of the Company, and by 3.5% in relation to the total capital stock of the Company. Conversely, SIG108 shareholding interest in the Company was reduced by the same proportion. Therefore, from that date on, SIG108 does not hold any interest at the Company.

On March 14, 2016, our board of directors approved a corporate restructuring in order to simplify our organizational structure. In the previous corporate structure, GVT Participações S.A. (“GVTPart”) was 100% owned by Telefonica Brasil, as shown below:

On the date of the merger, GVT was split and its net assets were transferred in part to GVTPart and in part to POP. The portion of the spun-off net assets of GVT concerning the goods, rights and obligations related to telecommunications activities were transferred to GVTPart and the remaining portion, concerning the assets, rights and obligations related to the other activities of non-telecommunications were transferred to POP. GVTPart was subsequently merged into Telefônica Brasil, resulting in the following corporate structure:

22

The corporate restructuring did not result in a capital increase or change in ownership of the Company’s shareholders and was ratified by an extraordinary shareholders’ meeting on April 1, 2016.

Acquisition of Telefônica Transporte e Logística Ltda. (TGLOG) by TData

On October, 28, 2015, TData, as buyer, and Telefónica Gestión de Servicios Compartidos España S.A., as seller, entered into a Stock Purchase agreement that resulted in the acquisition of Telefônica Transporte e Logística Ltda., a company headquartered in Brazil that provides logistics services.

Acquisition of Terra Networks by TData

On July 3, 2017, we announced that our wholly-owned subsidiary, Telefônica Data S.A. (“TData”), acquired all the shares of capital stock of Terra Networks Brasil S.A. (“Terra Networks”) from SP Telecomunicações Participações S.A. (“SPTE”), one of our controlling shareholders (the “Terra Networks Transaction”).

Terra Networks is a provider of digital services (own and third-party value-added services (“VAS”) and carrier billing, as well as mobile channels for sales and relationships) and advertising. TData is a company dedicated to the exploration of VAS, as well as integrated business solutions in telecommunications, technical assistance of telecommunications equipment and networks, maintenance of equipment and networks and development of projects. The purpose of the Terra Networks Transaction was to expand and integrate our offering of digital services, in order to provide additional value to our customer base and TData’s, as well as to provide TData’s offering of services to Terra Networks’ customer base and subscribers. In addition, the Terra Networks Transaction was intended to amplify TData’s advertising business as a result of Terra Networks’ nationwide operations and expertise.

By combining the Company’s skills in creating new digital media products for mobile and advertising and Terra Networks’ know-how in sales, customer service and operating digital services for specific customers, we believe the acquisition by TData will facilitate the exchange of know-how between the companies involved, and increase the consistency of commercial terms among the companies and their suppliers.

The total price paid by TData as consideration for the acquisition of shares issued by Terra Networks was R$250 million, paid in a single installment using TData’s cash on hand, with no need for financing. Such value was calculated based on our estimated valuation of the company, using a discounted cash flow model, based on an appraisal report commissioned by TData’s board of directors.

The Terra Networks Transaction is subject to conditions usually applicable to this type of deal, and was preceded by legal and financial diligence in relation to Terra Networks and valuation by an independent company. In addition, the respective sale and purchase agreement contains terms and provisions common to this type of transaction. The Terra Networks Transaction is not subject to obtaining any regulatory authorizations or approvals by the Company’s regulators and was structured in a way that does not change our shareholding structure or cause any dilution to our shareholders, seeking to generate value through an accelerated growth of digital services and increased operational efficiency. There are no significant costs related to the Terra Networks Transaction.

Capital Expenditures

Year Ended December 31, 2017

In 2017, we invested R$7,998.3 million, a 2.3% decrease over the amount we invested in 2016 (R$8,189.1 million), primarily due to the fact that we had no spectrum licensing costs in 2017, compared to R$185 million in spectrum licensing costs in 2016. Investments in projects were strongly focused on network investments (which accounted for 85% of investments in 2017) and included expenditures on items such as radio access network (Node-Bs, eNode-Bs and WCDMA carriers), transmission backhaul and backbone, FTTH and copper network. The investments helped sustain our commercial and revenue growth while maintaining the quality of the services provided and are also designed to prepare us for medium-term growth.

To meet the needs of an increasingly data driven and connected society, significant investments were made to support the strong growth of data usage in our residential fiber network, mobile 4G/3G network and dedicated corporate networks. We continue to invest in expanding our national data transmission backbone to meet the increase in data traffic throughout Brazil.

The following table sets forth our capital expenditures for each year in the three-year period ended December 31, 2017.

	Year ended December 31,
Telefônica Brasil	2017	2016	2015
	(in millions of reais)
Network	6,783.5	6,743.9	6,557.6
Technology / Information Systems	883.3	929.5	870.3
Others(1)	331.5	515.6	239.6
Total capital expenditures	7,998.3	8,189.1	7,667.5

(1) Consists primarily of handset sales made to corporate customers for the length of their contracts, furniture and fixtures, office equipment and store layouts and spectrum licensing costs. The spectrum licensing costs amounted to R$0.1 million in 2015, relating to the acquisition of the new 700MHz frequency spectrum and R$185 million in 2016, relating to the acquisition of the remainder of the 2,500 MHz spectrum for 4G usage. We had no spectrum licensing costs in 2017.

Year Ended December 31, 2016

In 2016, we invested R$8,189.1 million, a 6.8% increase over the amount we invested in 2015, primarily due to the cost of acquiring the remains of the 2,500MHz 4G spectrum (R$185 million) and also because GVT’s capital expenditures from January 1, 2015 to April 30, 2015, which totaled R$582.9 million, were not consolidated in our 2015 financial statements. Investments in projects were strongly focused on network (which accounted for 84% of investments in 2016, excluding licenses) and included expenditures on items such as radio access network (Node-Bs, eNode-Bs and WCDMA carriers), transmission backhaul and backbone, FTTH and copper network. The investments helped sustain our commercial and revenue growth while maintaining the quality of the services provided and are also designed to prepare us for medium-term growth. To meet the needs of an increasingly data driven and connected society, significant investments were made to support the strong growth of data usage in our residential fiber network, mobile 4G/3G and dedicated corporate networks.

Year Ended December 31, 2015

In 2015, considering the consolidation effect of GVT from May 1, 2015, we invested R$7,667.5 million, a 16% decrease over the amount we invested in 2014, primarily due to the cost of acquiring the new 700 MHz frequency spectrum, in an amount of R$2,770 million. However, the consolidation of GVT’s investment partially compensated for the decrease in investments with spectrum licenses (20% increase in capital expenditures, excluding licenses). Investments in projects were strongly focused on network (which accounted for 86% of investments in 2015, excluding licenses) and included expenditures on items such as radio access network (Node-Bs, eNode-Bs and WCDMA carriers), transmission backhaul and backbone, FTTH and copper network. The investments helped sustain our commercial and revenue growth while maintaining the quality of the services provided and are also designed to prepare us for medium-term growth.

B.    Business Overview

We are the leading mobile telecommunications company in Brazil (31.7% market share as of December 31, 2017, based on accesses), with a particularly strong position in postpaid mobile services (41.8% market share as of December 31, 2017, based on accesses). We are also the leading fixed telecommunications company in the state of São Paulo where we began our business as a fixed telephone service provider pursuant to our concession agreement. In the same period, we reached almost 44.8% of market share in ultra-fast broadband accesses with speeds higher than 34 Mbps in the state of São Paulo.

According to ANATEL’s customer service performance index, we are and have been the highest-quality mobile operator in Brazil. Our Vivo brand, under which we market our mobile services, is among the most recognized brands in Brazil. The quality of our services and strength of our brand recognition enable us to, on average, achieve higher prices relative to our competition and, as a result, generally earn higher margins. As of December 31, 2017, our average revenue per mobile user, or ARPU, of R$29.20 represented a significant premium relative to the market average of R$17.30 (considering the average Mobile ARPU of Claro, TIM and Oi for the third quarter of 2017). In 2017, we captured 39.3% of the 8.6 million net additions in the postpaid mobile segment. We offer our clients a complete portfolio of products, including mobile and fixed voice, mobile data, fixed broadband, ultra-fast broadband, or UBB (based on our Fiber to the Home, or FTTH and Fiber to the Curb, or FTTC infrastructure), Pay TV, information technology and digital services (such as entertainment, cloud and financial services). We also have one of the most extensive distribution networks of the sector, where our clients can obtain certain services, such as purchasing credit for prepaid phones.

We seek to continue to increase our operating margins by focusing on developing and growing our product offerings so that they comprise an integrated portfolio of higher-margin services. As part of this strategy, we acquired GVT in 2015, a high-growth telecommunications company in Brazil that offers high-speed broadband, fixed telephone and Pay TV services to high income customers across its target market, primarily located outside the state of São Paulo.

Our Operations and Services

Our operations consist of:

·local and long distance fixed telephone services;

·mobile services, including value-added services;

·data services, including broadband services and mobile data services;

·Pay TV services through DTH (a satellite technology), IPTV and cable;

·network services, including rental of facilities, as well as other services;

·wholesale services, including interconnection;

·digital services;

·services designed specifically for corporate customers;

·the sale of wireless devices and accessories.

Fixed Voice Services

Our fixed line services portfolio includes local, domestic long-distance and international long-distance calls provided both on the public and private regime.

25

Local Service

Fixed local services include activation, monthly subscription, public telephones and measured services. Measured services include all calls that originate and terminate within the same area code within our concession region, which we refer to as local calls.

Intraregional, Interregional and International Long-Distance Services

Intraregional long-distance services consist of all calls that originate in one local area or municipality and terminate in another local area or municipality within our concession region. Interregional long-distance services consist of state-to-state calls within Brazil and international long-distance services consist of calls between a phone line in Brazil and a phone line outside Brazil. We were the first telecommunications company to be granted the authorization to develop local, intraregional, interregional and international services throughout Brazil, including outside our concession area.

Mobile Services

According to data regarding market share published by ANATEL, we are among the leading providers of mobile telecommunications services in Brazil.

Our mobile portfolio includes voice and broadband internet access through 3G and 4G as well as value-added services, family plans, including voice mail, voice mail translation in speech-to-text, caller identification, voice minutes in unlimited bundles to other mobile phones of postpaid customers, ring tones, and innovative services such as multi-media backup, cloud based services to save texts, entertainment and music apps, advertising platforms, among others.

We also offer wireless roaming services through agreements with local mobile service providers throughout Brazil and other countries, allowing our subscribers to make and receive calls while outside of our concession areas.  We provide reciprocal roaming rights to the customers of the mobile service providers with which we have such agreements.

Data Services

We provide fixed broadband through xDSL technologies, coaxial cable and fiber (FTTH – fiber-to-the-home and FTTC – fiber-to-the-curb), with speeds ranging from 1Mbps to 300Mbps.

In 2017, we covered 100% of the municipalities in our concession area in the state of São Paulo, reaching more than 7.4 million fixed broadband customers, and we expanded our national fiber network to reach more than 18 million homes.

In 2010, we began offering the “Banda Larga Popular,” an initiative of the government of the state of São Paulo to provide broadband at affordable prices to the low-income population. This product currently has a top speed of 2Mbps.

Through the GVT acquisition in 2015, we were able to further expand our data services by providing high speed broadband to high income customers across our target markets. GVT provided services that were complementary to our own, with limited overlap with the services we already provided. Such complementary services included fiber broadband to locations in the state of São Paulo (outside of the city of São Paulo, where we already have a large presence) and nationwide.

In mobile broadband, we use a variety of technologies to provide wireless internet services to our customers. Our 3G network is currently available nationwide. In addition, we offer the HSPA+ technology, commercially known as 3G Plus. This technology allows customers with compatible terminals (including handsets) to reach up to three times the speed of traditional 3G. In December 2017, we covered 4,027 municipalities with our 3G network, reaching 92.7% of Brazil’s population. We also offer the 4G LTE technology, which, by the end of 2017, was available in 2,600 municipalities, reaching 84.5% of Brazil’s population, and also 4G+ LTE through carrier aggregation in 118 municipalities.

26

Pay TV Services

We began offering subscription-based television, or “Pay TV,” services via DTH (“direct to home,” a special type of service that uses satellites for the direct distribution of television and audio signals to subscribers) on August 12, 2007. We currently provide Pay TV services by means of DTH and IPTV (a type of service that offers video broadcast through the use of IP protocol) technologies and as of December 31, 2017, had 1.6 million Pay TV customers, including more than 381 thousand IPTV customers.

Network Services

Our network management technology ensures comprehensive management and supervision of all our network processes and network performance for our wholesale clients. We have two Network Management Centers, one located in São Paulo (with a remote team in Minas Gerais) and another located in Curitiba. These centers monitor all regions of the country, but each has a different function.

The Network Management Center in São Paulo monitors the critical network operational parameters of the countrywide transmission backbone, IP networks, broadband networks, packet/circuit core networks, VAS/Multimedia platform and global services. The remote team in Minas Gerais monitors the critical operational parameters of the radio access network, infrastructure and online services performance. The Network Management Center in Curitiba monitors the critical operational parameters of the countrywide transmission backbone, network interconnection and IPTV/DTH networks. These centers are able to identify abnormalities in both our network and in third-party networks, using failure and signaling monitoring systems. In addition, quality and service standards are constantly monitored. The Network Management Centers are integrated with maintenance and operations teams that maintain and operate cellular network elements, as well as cellular infrastructure and transmission, in addition to the radio network elements and computing bases, service platforms and communications backbones.

Our network provides for continuity of service to our customers in the event of network interruptions. We have developed contingency plans for potential catastrophes in our switchboard centers, power supply interruptions and security breaches.

We continuously aim to consolidate our network and increase its offerings, to deliver the best possible service to our customers and to meet their expectations.  Some of the improvements we have made in recent years include advancements in the migration of time-division multiplex switches to next generation network switches, which offer new digital services to our clients and reduce our maintenance costs, including improvements in levels of security, power supply, battery and air conditioning infrastructure. The most significant implementation of technology has been a project to exchange optical cabinets, used for offering voice and data services for Multi-Service Access Nodes, which allows us to offer broadband service to a large number of clients who did not previously have this service.

Network and Facilities

We provide industrial exploration of dedicated linesor (Exploração Industrial de Linha Dedicada), EILD, pursuant to our concession agreement and our authorization agreements. The EILD consists of the rental of dedicated circuits and clear channel protocols for the provision of services to third parties.

In addition, we are able to offer a complete portfolio of wholesale products, including L2L, IP, ETHERNET, MPLS and GPON. All of these products are used to meet the demands of other network operators and regional internet providers. The circuits are requested with different service level agreements, and we are required to provide the facilities with contingency routes, sites and equipment to improve the service against points of failure.

Our network consists of an access layer that connects our clients through our copper or optical networks, which are connected to voice and data centers. These centers are interconnected locally or remotely through transmission equipment connected predominantly with fiber optics and occasionally through a microwave network, which together form a network layer that enables connectivity between the various central aggregate service platforms as well as interconnection with other carriers. Our network strategy is based on the expansion of the fiber optic access network to allow greater coverage and broadband services for our customers, as well as to develop an integrated multiservice network and multimedia applications. As a telecommunication service provider, we do not manufacture equipment for the construction of our networks and facilities. We buy the equipment from qualified suppliers in Brazil and abroad and through such equipment we implement our networks and facilities through which we supply our services.

27

Wholesale Services (including Interconnection)

We have continuously adapted and expanded our network topology aiming to develop new business opportunities throughout Brazil by offering services to other telecommunications companies. The result has been a significant increase in the number of providers that use our wholesale services.

As part of our wholesale services, we provide interconnection services to users of other network providers.  We earn revenue from any call that originates from another mobile or fixed-line service provider network connecting to one of our customers.  We charge the service provider from whose network the call originates an interconnection fee for every minute that our network is used in connection with the call. See “—Operating Agreements—Interconnection Agreements.”

At the end of 2017, we had 439 local and long-distance interconnection agreements and 124 agreements for provision of local traffic and long-distance.

The interconnection is a link between compatible telecommunications networks which permits that a fixed or mobile service user of one network can adequately communicate with the users of a network from another provider.

All providers of telecommunication services (fixed or mobile) are required to provide interconnection upon request to any other telecommunication collective service provider. The conditions for interconnection agreements may be freely negotiated among the parties. The agreements are required to be formalized by contract, whose effectiveness depends on ANATEL’s approval. If any given agreement is contrary to the principles of free competition or conflicts with other regulations, ANATEL may reject it. If the parties cannot reach an agreement on the terms of interconnection, including the interconnection fee, ANATEL may determine those terms and conditions by arbitration.

Digital Services (including Value Added Services)

In 2017, we accelerated the process of becoming a digital telecommunications company, launching relevant services, with high perceived value, in areas such as entertainment, education, advertising, e-health, security, financial services, insurance and machine-to-machine operations. In entertainment, for example, Vivo became the NBA official carrier in Brazil. Because of this exclusive partnership, Vivo customers can access exclusive content of the most important basketball league in the world. In addition, Vivo also offers NBA League Pass, a premium service with all NBA games, including regular season, playoffs and finals, for a special price. We have also a partnered with Editora Abril, the leading magazine publisher in Brazil, to become the exclusive distributor in the telecommunication segment of GoRead app, Brazil's largest digital magazine platform, with more than 190 titles available to the service subscribers.

In our education services, we launched the Vivo Educa app, a platform of courses in the following categories: preparatory courses, career development, school support, personal finance, cooking and gastronomy, children and technology. Courses can be accessed through video lessons, online books with complete content and exercises, and live sessions.

In our security services, we launched the Vivo Protege app, a solution that guarantees the security of information on mobile phones, tablets and notebooks, bringing together five complementary services – storage and synchronization of files with security and privacy in the cloud, antivirus and antitheft, parental control, Wi-Fi browsing protection and a 24x7 online technical support.

In our e-health services, we launched the Vivo Meditação app, a new digital service that helps customers to develop concentration and mindfulness. It is the best-in-class app in Portuguese, with more than 1,000 guided meditation exercises, including exercises designed for kids.

28

In our advertising services, Vivo Ads has become one of the main mobile media platforms in Brazil, offering solutions for video campaigns, email lists and lead generations, app installations and other media-related content. Of the ten largest advertisers in Brazil, eight already use our platform in a recurring way in their marketing strategies. Vivo Ads was also one of the three finalists of the Caboré Prize, the main prize of the advertising market of Brazil, in the category Communication Vehicle - Media Platform.

Corporate

We offer our corporate clients comprehensive telecommunications solutions and IT support designed to address specific needs and requirements of companies operating in all types of industries (retail, manufacturing, services, financial institutions, government, etc.).

Our clients are assisted by our highly qualified professionals who are capable of meeting the specific needs of each company with voice, data, broadband and computer services solutions, including hardware and software (for example, anti-virus software). We work to consistently achieve greater quality and efficiency in our services and increase our level of competitiveness in the market.

Sale of Devices and Accessories

In addition, we sell handsets and accessories at our physical stores, to customers who purchase our digital services. We sell WCDMA and LTE devices such as smartphones, broadband USB modems and devices that are certified to be compatible with our network and service. We have special offers on smartphones, USB modems and other data devices for customers of bundled packages. Our current device suppliers are Motorola, LG, Samsung, Alcatel, Apple, D-Link, ZTE, Flex (WNC) and our accessories suppliers are Harman (JBL), Alfacomex (SanDisk and Geonav), Comesp (SanDisk) and Easy Mobile.

Rates, Taxes and Billing

Rates

We generate revenue from (i) activation and monthly subscription charges, (ii) usage charges, which include measured service charges, (iii) interconnection fees that we charge to other telecommunications service providers, and (iv) other additional services. Rates for all telecommunications services are subject to extensive regulation by ANATEL. We set forth below the different methods used for  calculating our rates.

Local Rates

Our concession agreement sets forth three mandatory plans for local fixed service, and allows us to design alternative pricing plans. Customers have a choice among three plans that we are required to offer or any other alternative plan that we may choose to offer. ANATEL must be informed of any alternative plan and notified of its implementation. The three main mandatory plans are:

·Local Basic Plan: for clients that make mostly short-duration calls (up to three minutes), during regular hours;

·Mandatory Alternative Service Plan (Plano Alternativo de Serviços de Oferta Obrigatória – PASOO): for clients that make mostly long-duration calls (above three minutes), during regular hours and/or that use the line for dial-up service to the internet; and

·Special Class Individual Access (Acesso Individual Classe Especial – AICE): a plan created specifically for families enrolled in social programs from the Brazilian government.

The following table outlines the basic billing requirements and gross rates for the Local Basic Plan and the Mandatory Alternative Plan as of the date of this annual report:

Characteristics of Plan	Local Basic Plan	Mandatory Alternative Service Plan
Monthly Basic Assignment
Allowance (minutes included in the residential assignment)	200 minutes	400 minutes
Commercial Assignment Allowance (minutes included in the commercial assignment)	150 minutes	360 minutes
Local Call Charges
Regular Hours
Completing the call (minutes deducted from the allotment)	–	4 minutes
Completing the call after the terms of the allotment Sector 31	–	R$0.17750
Local Minutes–charges in excess use of the allotment Sector 31	R$ 0.11425	R$0.04436
Minimum time billing	30 seconds	–
Reduced Hours
Charge per answered call (minutes deducted from allotment)	2 minutes	4 minutes
Charge per answered call after the allotted duration Sector 31	R$0.22260	R$0.22260

29

As of the date of this annual report, the subscription to the AICE plan costs R$7.81 and allows for 90 minutes of local fixed-line calls per month. Any additional fixed or mobile calls may be made only if the customer purchases prepaid credits. The prices of mobile and long-distance calls are determined pursuant to a standard plan.

Our concession agreement also sets forth criteria for annual fee adjustments for all of our plans for local fixed service. We derive a substantial portion of our revenue from services subject to this price adjustment. The method of price adjustment is an annual price index correction applied by ANATEL to our local and long-distance fees that reflects the inflation index for the period and a productivity factor, which is calculated based on a compensation index established by ANATEL to share earnings from fixed charge services with their users. Currently, the inflation index used by ANATEL is the IST, which reflects variations in telecommunications companies’ costs and expenses. ANATEL has consistently complied with the fee range set by the concession agreements.

Long-Distance Rates

Rates for domestic long-distance calls are computed on the basis of the time of day, day of the week, duration and distance of the call, and also may vary depending on whether special services, including operator assistance, are used. We have several options of domestic long-distance calling plans for consumers using our carrier dial code (15).  Customers of any local and long-distance operator may use Code 15 when dialing long-distance and will benefit from our rates. To readjust the long-distance local rates, ANATEL applies an annual price index correction that reflects inflation.

We also offer international long-distance rates, which are also available to all users using Code 15. International long-distance call charges are computed on the basis of the time of day, day of the week, duration and destination of the call, and also may vary depending on whether special services are used or not, including operator assistance. Our rates for international services are not subject to regulation and are not required to follow the annual rate adjustment described above for other services. We are free to negotiate our fees for international calls based on the international telecommunications market, to which our main competitor is Embratel.

With respect to long-distance calls, we have developed alternative rate plans for residential and corporate customers.

30

Mobile Services Rates

With respect to our Local Basic Plan, as described above, and certain roaming charges incurred in connection with alternative service plans, our authorizations provide for a mechanism to set and adjust rates on an annual basis. The maximum rate is calculated as the current rate plus the rate of inflation. The maximum rate is revised annually and the rate of inflation is measured by the IGP-DI index. The maximum rate is applicable to all service plans, but mobile operators are able to freely set the maximum rates for alternative service plans (other than with respect to certain roaming charges).

The initial price cap agreed by ANATEL and us in our authorizations was based on the previously existing or bidding prices, and has been adjusted annually on the basis of a formula contained in our authorizations. As of the date of this report, the most recent adjustment was approved in February 2017 and established the tariffs of R$0.20981 for regular hours and R$0.14686 for reduced hours.

Other telecommunications companies that interconnect with and use our network must pay certain fees, primarily an interconnection fee. The interconnection fee is a flat fee charged per minute of use that directly affects the mobile services rates. Since 2005, ANATEL has allowed free negotiations for mobile interconnection fees (MTR).

In December 2013, ANATEL established the reference values for MTR for 2014 and 2015, and in July 2014, for the years 2016, 2017, 2018 and 2019. The table below shows the ranges for these reference values:

Year	Reduction in %	MTR in reais
2014	25	0.22164 – 0.25126
2015	33	0.14776 – 0.16751
2016	37	0.09317 – 0.11218
2017	47	0.04928 – 0.06816
2018	47	0.02606 – 0.04141
2019	50	0.01379 – 0.02517

Interconnection Fees

We are paid interconnection feesby any fixed-line or mobile service provider that either originates or terminates a call within our network. We also pay interconnection fees to other service providers when we use their network to place or receive a call. The interconnection agreements are freely negotiated among the service providers, subject to a price cap and to compliance with the regulations established by ANATEL, which include not only the interconnection basic costs including commercial, technical and legal aspects, but also the traffic capacity and interconnection infrastructure that must be made available to requesting parties. If a service provider offers to any party an interconnection fee below the price cap, it must offer the same fee to any other requesting party on a non-discriminatory basis. If the parties cannot reach an agreement on the terms of interconnection, including the interconnection fee, ANATEL can establish the terms of the interconnection. For additional information about interconnection fees, see “—Regulation of the Brazilian Telecommunications Industry—Obligations of Telecommunications Companies—Interconnection.”

Data Services Rates

We receive revenue from charges for data transmission, which includes our fixed broadband, dedicated analog and digital lines for privately leased circuits to corporations and others services. Data transmission rates are not regulated by ANATEL, except for EILD. Multimedia services operators are able to freely set the rates for alternative service plans.

31

TV Rates

Pay TV rates are not regulated. Service providers are able to freely set the rates for alternative service plans.

Taxes

The cost of telecommunications services to each customer includes a variety of taxes. The main tax is a state value-added tax, the Imposto sobre Circulação de Mercadorias e Serviços, or ICMS, which the Brazilian states impose at rates ranging from 7% to 35% on certain revenues from the sale of goods and services, including telecommunication services.

Other taxes include: (1) Federal Social Contributions (Contribuição para o Programa de Integração Social), or PIS, and Social Security Financing Contributions (Contribuição para o Financiamento da Seguridade Social), or COFINS; (2)Fund for Universal Access to Telecommunications Services (Fundo de Universalização dos Serviços de Telecomunicações), or FUST; (3) the Telecommunications Technological Development Fund (Fundo para o Desenvolvimento Tecnológico das Telecomunicações), or FUNTTEL; and (4) Fund for Telecommunications Regulation (Fundo de Fiscalização das Telecomunicações), or FISTEL.

Billing

We send each contract customer a monthly bill covering all of the services provided during the previous monthly period. Pursuant to Brazilian law, telephone service providers are required to offer their customers the choice of at least six different monthly payment dates.

We have a billing and collection system with respect to local, national and international long-distance voice, subscriptions, broadband, data, IT services, outsourcing, television and third-party services. For invoice payments, we have agreements with various banks.  These agreements include options for customers to select their preferred payment type: direct debit, payment to a bank, Internet and other collection agencies (including lottery-playing facilities, drugstores and supermarkets). We aim to avoid losses in the implementation of new processes and the roll-out of new products through the monitoring of billing, collection and recovery controls. The billing process is audited by the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas), or ABNT. These practices are closely monitored by our revenue assurance team, which measures every risk of revenue loss detected along the billing and collection chain. These risks are managed to minimize revenue losses.

Co-billing

In accordance with Brazilian telecommunications regulations, we use a billing method called “co-billing” for both fixed and mobile services. This method allows billing from other phone service providers to be included within our own invoice. Our customers can receive and subsequently pay all of their bills (including the fees for the use of services of another telephone service provider) on our invoice. To allow for this method of billing, we provide billing and collection services to other phone service companies. We have co-billing agreements with national and international long-distance phone service providers. Similarly, we use the same method of co-billing to bill our services to customers of other fixed and mobile providers. This service is charged to the long-distance operator, by means of a call record described in the invoice.

For customers who use our long-distance services through operators that have no joint billing agreement with us, we use direct billing through the national registry of clients.

Value Added Services

Value added services such as entertainment, information and online interactivity services are available to mobile prepaid as well as postpaid customers through agreements with content suppliers. These agreements are based on a revenue-sharing model.

32

Third-party Services

We incorporate third party services in our billing, collection and transfer process.  These services are later passed on to the third party contractor.

Collection

Our collection policies with respect to customers in default follow ANATEL regulations, as well as those of Serviços de Telecomunicações, or RACO, and the Foundation for Consumer Protection and Defense (Fundação de Proteção e Defesa do Consumidor), or PROCON. For mobile, fixed and Pay TV customers, as a general rule, if payment is more than 15 days overdue, service can be partially suspended by blocking out-going calls that generate costs to the customer. If payment is more than 30 days overdue after this partial suspension, the service can be fully suspended, disabling all services (out-going and incoming calls), until payment is received. We offer an installment payment plan for clients with overdue balances. However, if accounts are not paid after 30 days following the total suspension, the contract can be cancelled and reported to credit protection agencies.

The collection process for customers in default involves several steps, from an internal interactive voice response, SMS contact, email contact, followed by a late payment notice, and finally reporting customer information to an external credit bureau.  Concurrently with our internal process, delinquent customers are also contacted by collection agencies. Customer risk profile, overdue debt and other quality issues are used to increase strategy efficiency and maximize debt recovery efforts. Amounts overdue by over 105 days, except for accounts receivables from interconnection fees and government and corporate customers (there is a specific rule for those exceptions), are considered provisions for doubtful accounts. In accordance with Brazilian regulations, bad debt write-offs are permitted for late payments of zero to R$5,000 if they are over 180 days late or R$5,001 to R$30,000 if they are over 365 days late. Late payments of over R$30,001 that are open for more than 365 days require the commencement of a lawsuit. This rule is applied for outstanding debt through October 8, 2014; after this period, amount ranges change as follows: zero to R$15,000 if they are over 180 days late or R$15,001 to R$100,000 if they are over 365 days late. Lawsuits are demanded for debts over R$100,000 open for more than 365 days.

In the year ended December 31, 2017, the monthly average of partial suspensions, for mobile and fixed services, was 4.3 million lines and the monthly average of total suspensions was 673,780 lines. For Pay TV services, the monthly average of partial and total suspension was 171,575 terminals and 21,650 terminals, respectively. Provisions for doubtful accounts in the year ended December 31, 2017 were 2.2% of the total gross revenue.

Seasonality

Our business and results of operations are not materially affected by seasonal fluctuations in the consumption of our services.

Marketing and Sales

Our commercial distribution network (marketed under the Vivo brand), as of December 31, 2017, consisted of 295 own sales outlets throughout Brazil. In addition, we also have approximately 12,000 sales outlets run by authorized dealers (including exclusive dealers and retail channels), maintaining a solid capillarity strategy that contributed to our leadership position in Brazilian telecommunications market.

In 2017, we had approximately 600,000 points of sale where prepaid mobile service customers could purchase credits. Prepaid phones can be credited remotely or by purchasing cards containing credits. Credits may also be purchased through credit and debit cards, call centers, Vivo PDV (M2M using a cell phone for transferring the credit), personal recharge (using the phone itself to recharge credits), as well as certain certified internet websites.

34

We bring our solutions to our clients through the following physical sales channels:

·Vivo stores: located in strategic points, our own stores provide a complete portfolio of products and services through a highly trained team, built to guarantee the best sales experience for the customer. Following the massive and increasingly digital transformation in the global community and environments, we have been adapting the way to offer our services in Vivo stores to customers. These changes include self-service terminals to offer after-sales services, as well as the convenience of scheduled appointments via the internet, delivery of SMS passwords and online queue tracking, all to minimize time spent waiting in lines. In addition, to improve customer experience, we launched the new iconic store at Barra Shopping Rio de Janeiro that transforms the traditional POS (Point of Sale) into a PDX (Point of Experience).

·Exclusive dealers: this channel is composed of select companies that have been certified to provide our full product portfolio.  These dealers comprise a wide distribution network throughout the country. Although the channel offers the entire product portfolio, its focus is on the postpaid product. We are also constantly updating and enhancing these stores to provide a better purchase experience to the customer, to ensure an experience that is consistent with our own stores.

·Retail channel: our retail channel sells postpaid and prepaid products and recharge services that are marketed by our partners' own sales teams. This channel utilizes a sales incentive program that focuses on sales of our postpaid product Controle and is tied directly to the performance of our retail partners’ salesforce.

·Distribution channel: the broadest and most complex sales channel across our markets, this channel allows our prepaid customers to purchase service credits. In order to be as close as possible to potential and existing customers, this channel comprises authorized agents, lottery stores, post offices, bank branches and small retailers, such as pharmacies, newspaper stands, bookstores, stationery shops, bakeries, gas stations, bars and restaurants.

·Door-to-door sales: aimed at approaching clients that our other channels cannot reach, we use niche physical channels, such as door-to-door sales of services by outsourced small companies and our own team of consultants. We focus mostly on voice products, as well as our postpaid Controle plans. In 2017, we began a transformation process through a new initiative targeting high-value customers in residential condominiums in order to achieve an increase in premium bundle accesses (fiber broadband and postpaid mobile services).

·Telesales: a channel with no geographical limitations, our telesales channel can reach existing and potential customers across the whole country, offering our full product portfolio, from prepaid to postpaid products, as well as fixed voice, broadband and TV bundles. We are able to identify a wide range of prospective new clients through our active outbound telesales operations, as well as to direct all incoming inquiries through our inbound telesales operations. This solid structure consists of our own telesales team and a select group of outsourced companies specialized in this business.

We also offer our services through digital channels, which are transforming our commercial model, making transactions more efficient and promoting the integration of all points of sale. In 2017, end-to-end digital sales in our mobile segment grew 460% throughout the year, delivering a consistent experience to customers and reducing commissioning costs. Meanwhile, in the fixed segment annual gross sales increased 10% during this year. The continuous improvement in e-commerce user experience was the most remarkable achievement, which contributes to our client’s digital experience and promotes Vivo’s digital presence and brand awareness.

Vivo’s self-service care platform “Meu Vivo” had a remarkable year in 2017: downloads improved 50% higher than previous year, reaching 24 million downloads. Unique users in the app had an annual growth by 88%. These efforts were expanded to B2B segments: our self-service care platform “Meu Vivo Empresas” increased unique users by 46%, while e-commerce sales boosted 59% during 2017.

35

The Company’s virtual assistant, Vivi, reached a landmark in accesses: in October, Vivi reached for the first time 1 million accesses in one month since its launch in October 2016, proving the customers growing demand for self-assisted platforms.

In order to explore all the digital strategic initiatives mentioned above and Internet’s businesses potential, the Company made special offers and promotions during Black Friday/Black November in Brazil, which reinforces Vivo’s digital maturity. Handset sales went up to 32% during 2017 compared to the same period in 2016.

Customer Service

In 2017, we reaped the benefit of certain measures that were implemented at the end of 2016 and the results of revised call center service contracts, which emphasized quality of services through a competition model between suppliers. In addition to these operational measures, we invested in the digitization of the service, always keeping the focus on quality. The highlights are self-service actions, customized menus and a more humanized experience with the IVR. 

Regarding customer service, our initiatives have been structured to leverage customers’ online experience, transform the customer care model and increase perceived quality in interactions. We continued to work on integrating the systems used in the operation, defining processes and business rules and internalizing operations considered fundamental for transforming the customer experience in all channels and points of contact.

Seeking to maintain our leadership position, we worked to expand digital channels and developed more self-service options, aiming to provide a unique and relevant multichannel experience for customers. Our customer care mobile app reached more than 40 million contacts in December 2017 and a growing number of unique users. We worked on the refinement of the assertiveness and scope of the Virtual Assistant Vivi, which today is already capable of answering more than 90% of the queries by means of artificial intelligence and interact with social medias like Tweeter and Facebook. We advanced in the humanization of our Customer Relationship Center’s electronic service, in a personalized way and with intelligent dialogue, streamlining the understanding of the request. In this process, we were able to provide answers to customers through the electronic service at levels of 72% in certain segments, shortening the path through a more convenient experience.

In 2017, we consolidated the new model of hiring of call center attendants with a repeated incentive to good performance, based entirely on quality goals, which led to an improvement of our operational indicators. We perceived a reduction in the contact rate in all segments, increased availability of agents, and increased the autonomy of representatives of the call centers to solve the customers’ requisitions in the first contact. All of these results, associated with the Customer Satisfaction Survey, demonstrate that we are on the right path, converting these interactions into a positive experience with the brand.

In 2018, Telefônica Brasil maintains the strategy of enriching content and increasing the functionalities available in each of the channels, seeking integration among them, so that a client can choose how to interact with us with a high-quality experience, regardless of which channel he or she selects. We will continue to accelerate the digitalization of the customer care, providing more agility, autonomy, standardization of experience in all channels and points of contact. The Company is totally focused in provide the best experience for the customer.

Technology

In order to offer a greater variety of integrated services, we have incorporated a series of new technologies in our voice and data networks.

We remain focused on the evolution and convergence of the mobile and fixed networks based on All-IP IMS technology, encouraging technological advancement and offering new services to our customers. The voice network is being prepared to initiate migrations of mobile subscribers 2G and 3G to Voice over LTE, or VoLTE, as well as fixed subscribers to VoIP. In addition to convergence and modernization, we will also invest in network virtualization promoting better use of network resources.

36

The voice network has been modernized with the use of new generation technology that improves redundancy, reliability and capacity. In addition, we have already started the implementation of VoLTE technology that will allow us to offer voice services over LTE access instead of CS (Circuit Switch) Fallback, or CSFB, which we currently use. As a result, we expect a faster call completion comparing with CSFB. We expect to improve the voice communication experience, offering voice service with HD quality that is native for VoLTE technology. We also have already started to implement Voice over FTTH technology that will allow us to offer voice services over FTTH access instead of voice over copper currently used. As a benefit, we expect to have cost savings for equipment, lines, manpower and maintenance. We also expect to offer new voice services, in order for that to be possible, a new Core infrastructure has already been installed in Vivo networks: the IMS Core, an ALL-IP framework that uses the IP protocol as the main protocol for the network.

We have equipped the network to support traffic bursts of enterprise inbound and outbound call center services, such as contact center and outbound dialing, by developing and implementing high-capacity and scalability core elements.  In 2018, in addition to convergence and modernization, we will also invest in network virtualization.

As more services migrate to IP, our IP backbone has become a strategic asset to support customer demands and increase revenues. The migration of sensitive and demanding services such as voice and television to IP has also increased the demand for higher quality broadband networks and is further augmented by growing products like cloud services and video on demand. At the same time, the expansion of fiber to customer homes and the launch of our 4G+ services (Carrier Aggregation) strongly increases bandwidth demands over the networks. As a result, three main drivers have surfaced as critical to our business: availability, performance and cost effectiveness.

To reach these goals, which may appear to conflict with each other, it is essential to optimize network resources and find synergy multipliers. The first step is to integrate Vivo’s and GVT’s IP Backbones, simplifying our network and avoiding redundant infrastructure. As we have done in the mobile and fixed integration, we have designed a robust architecture, using two distinct backbones to provide public and private services using multi-protocol networks infrastructures, to guarantee service reliability to our clients and the deployment has already begun in 2018.

Nonetheless, as more and more bandwidth is offered to customers, the need to bridge the gap between revenues and investment to cope with greater traffic becomes increasingly clear. Therefore, network simplification must evolve to a deeper level, unifying specialized routers, reducing network layers, bringing services and content nearer to customers and, ultimately, transforming the backbone into one multiservice network. The new design acknowledges service evolution, as voice, messages and circuits becomes data packets and reduces the need of growing capacity in multiple hops.

Those actions not only optimize investment in an aggressive traffic increase context but also lay the grounds to deliver the next step in data services quality. Even though bandwidth has been the main technical advantage for several years, latency will take over as the main broadband selling point. To reduce network latency means delivering more responsive services and obtaining higher customer satisfaction.

In order to achieve this result, from the IP point of view, service has to be decentralized and nearer the edge of the network, closer to customers. In 2016 and 2017, by greatly expanding the use of caching solutions throughout the network, we have made content locally available to our customers, not only reducing transport costs but also strongly improving user experience without increasing access investments. We believe that in the coming years, layer simplification could allow us to bring content even further to the edge, improving costs and quality at the same time.

We further optimized costs by sharing access networks with other Brazilian operators, in which IP backbones played a key role in connecting and transporting traffic among different operator’s networks, reducing the need for mobile sites expansion.

37

Finally, as the Internet address numbers in Brazil were exhausted in 2014 and our own resources are reaching critical levels, we have seen strong growth in the next version of the IP protocol, the IPv6. Vivo has completed IPv6 project in 2017 and received the Jim Bound Award from the IPv6 Forum for surpassing 10% of its Internet Traffic in IPv6. In fact, 40% of the traffic is already running in the new protocol version and we are part of the top 15 companies in the world in IPv6 traffic volume, according to the specialized measurement site World IPv6 Launch (http://www.worldipv6launch.org). Not only this is important to guarantee full connectivity to our clients but also to support sales and keep expanding our customer base.

In projects related to Local Area Network (LAN), we provide local connectivity to all platforms and servers that provide telecommunications service, fixed or mobile. The Local Area Network works as access for all services to the data network by connecting them to the IP Backbone.

Since 2014, we have adopted the strategy of evolving Ethernet Standard on all sites to a Fabric structure, using the concepts of Top Of Rack - TOR and End Of Row - EOR according to port density. It is a more robust technology, more resistant to failures and cheaper, since the network equipment is decentralized, generating in this way an economy in structured cabling and consequently reduction of cooling, energy consumption and physical space. In 2017, we implemented this concept in 23 sites.

In 2016, we implemented the Cache solution to reduce bandwidth consumption on the IP backbone by locally storing content from partners such as Google, Netflix, Akamai, and Facebook. With this, we can optimize network resources, improve service quality and user experience. In 2017, the Cache framework was expanded in six more sites.

Since 2014, we saw a variety of targets and natures of attacks with regards to cyber security, with special attention to the mobile terminal, where we already offer a comprehensive suite of applications for mobile security. On the network side, besides tightening our perimeter security, we have been focused on automation. Periodic tasks such as analyzing attacks notifications, auditing firewalls rules and evaluating security elements performance have been the main areas subject to automation, allowing security professionals to focus on problems that are more complex. In 2017, we increased the traffic capacity to be detected and mitigated by the protection tools against attacks coming from inside and outside our network.

We offer the IPTV service through the FTTH network using the Open Platform, created to revolutionize the way that Telefonica delivers the IPTV service. This platform consists of Pay TV with video broadcasting offered through the IP protocol. It consists of several global partners, developing modules in partnership with Telefonica and connecting into the exiting Global Video Platform. Our local team customized the middleware for Set-Top-Box, creating one standard version which brings better time-to-market for new developments and product releases, as well as future convergence between IPTV and DTH platforms. Several components were integrated to create a whole new ecosystem for IPTV, such as the inclusion of Instant Channel Change (ICC), Retransmission and Applications providing a better user experience. Additional services, such as pay-per-view and VoD, are also available. 

For the year of 2018, we will continue to expand all the services to other cities within Brazil as the FTTH network expands. Also other companies from Telefonica based in Latin America will have the opportunity to receive the developments made in Brazil to deliver the same service and features to their clients. Besides the expansion to other cities, new features will be incremented on the client for a better experience, such as Time Shift, Catch Up, PiP, 4K content and new Apps.

We also offer digital television service via satellite (DTH) to the subscribers that receive broadcast/PPV content through a Ku band antenna and standard Set Top Box (with Smart Card), also available with a Personal Video Record (PVR) service with 4K technology. The customer has additional services through IP protocol when connecting the Set-top-box into broadband service, offering VoD and interactive applications. After four years, we expect to use one satellite and one Middleware solution consolidating in a single platform.

Our development plan contemplates the use of the most advanced technology available, focusing on integration with the internet and an increase in the number of multimedia transmission services, with an emphasis on DSL, FTTH (GPON), NGN, DWDM, ROADM and relays technologies of TV over IP protocol (IPTV), satellite (DTH), and the continuous evolution of TV services.

38

We currently offer HSPA+ technology, commercially known as 3G Plus, across 100% of our WCDMA coverage, allowing customers that have compatible terminals to achieve up to three times more than traditional 3G rate. Since 2013, we offer the LTE system in spectrum (2600 MHz). At the end of 2017, 2,600 Brazilian cities had 4G availability.

Since 2015, we started to develop the network sharing in 4G with OI and TIM. At the end of 2017, 128 Brazilian cities had radio base stations shared, and in 292 cities we provided new 4G coverage with RAN Sharing using infrastructure from TIM or OI. In 2017, we also started to develop network sharing in 3G with Claro, and at the end of 2017, 158 Brazilian cities had radio base stations shared, and in 141 cities we provided new 3G coverage with RAN Sharing using infrastructure from Claro. The strategy of Radio Access Network Shared allow us to fulfill part of the ANATEL’s requirements due the LTE spectrum acquisition.

Since 2016, we started to offer new frequencies to LTE (700MHz and 1800MHz) activating 4G+ services as well, with goal to improve the coverage, capacity and customer experience (4G+ permit to reach up to double of 4G throughput). At the end of 2017, we had 2,078 sites with LTE 700MHz and 4,189 sites with LTE 1800MHz.

Fraud Detection and Prevention

During 2017, we continued our work in combating the two main types of fraud, as follows:

·Subscription fraud: is a type of fraud that occurs when the issuance of one or more accesses are granted without the consent of the real “holder” of identification documents with the main objective of evading payment. We had a decrease of 69% in subscription fraud-related losses, from R$37.9 million in 2016 to R$11.7 million in 2017. The main cause of this decrease was the review of certain detection processes and improvement of the controls used in monitoring fraud events during the year allowed us to capture more fraudulent cases relatively to the expansion of our network.

·Identity Fraud: also known as “social engineering”, identity fraud takes place through call centers or dealers, where a caller who has access to information belonging to our existing clients reaches out to our call centers and makes unauthorized alterations and activations. We did not have any losses related to Identity Fraud for financial accounts of expenses, representing 100% of effectiveness in 2016. The main reason for this result was the identification of cases in a shorter period of time.

Operating Agreements

Interconnection Agreements

The terms of our interconnection agreements include provisions with respect to the number of connection points and traffic signals. See “—Regulation of the Brazilian Telecommunications Industry—Obligations of Telecommunications Companies.”

We believe that we have adequate interconnection agreements with fixed-line operators necessary to provide our services and that we have all the necessary interconnection agreements with long-distance carriers.

39

Roaming Agreements

We provide international GSM roaming in over 200 destinations worldwide by means of over 500 roaming agreements with local service providers.

Network Sharing Agreement

In 2014, Telefônica Brasil announced that a network sharing agreement with Nextel was signed to provide mobile services coverage (voice, data and SMS) through our 2G and 3G network to 67 area codes. The contract is a five-year term, with a minimum payment of R$1.0 billion for the whole period as follows: (i) R$44.3 million in the first year; (ii) R$132.1 million in the second year; (iii) R$237.1 million in the third year; (iv) R$263.0 million in the fourth year and (v) R$361.5 million in the fifth year. Terms and payments are subject to the fulfillment of the contractual obligations assumed by the parties.

ANATEL approved the agreement and the execution of the operation in March 2014. The network sharing has been fully operational since July 31, 2014, when the Parties executed the Notice of Network Full Availability.

In 2016, both parties decided to extend the agreement throughout the national territory. The extension was approved by CADE in July 2016 and by ANATEL in August 2016. ANATEL’s approval was conditioned to the effective commercialization of SMP service in the locations subject to Nextel obligations. The agreement will be revised by the regulator in two years and could be terminated depending on the parties’ compliance with related obligations. Nextel has appealed on the conditions mentioned above, which are currently under review.

In March 2015, Claro and Telefônica entered into a RAN Sharing agreement in order to provide telecommunication coverage in rural areas in Brazil, which was approved by CADE and ANATEL.

In December 2015, Telefônica, Oi and TIM entered into a RAN Sharing agreement in order to provide mobile services coverage (voice, data and SMS) through the 4G network and comply with coverage commitments assumed by the operators. The agreement was approved by CADE and ANATEL.

In August 2016, ANATEL approved the agreement between Telefônica and TIM to share electronic equipment and mobile sites for the fulfilment of the obligations in order to provide telecommunication coverage in rural areas.

The approval of the aforementioned agreements, however, does not exempt the providers from fulfilling their obligations, nor from the coverage of the entire area. In the case such agreements are terminated before the expected deadline, each provider must meet its coverage commitments with its own network, under the penalty of extinction of the use of radio frequencies’ authorizations.

Competition

Competition in the fixed and mobile markets continued to be intense in 2017.Faced with the high demand for connectivity, Brazilian telecoms have focused on modernization and innovation as levers to remain competitive in the market. The leading companies have been directing efforts and investments towards the digital transformation of business operations, aiming to improve the balance between customer growth and loyalty, revenue growth and margins.

The Brazilian consumer market is increasingly knowledgeable and demanding, expecting not only the best service delivery, as well the best cost-benefit. Therefore, operators have prioritized the expansion and digitalization of company-customer interactions.

In the mobile market, we continued to lead in market share, with a 31.7% share according to information from ANATEL as of December 2017. This year, the competition remained aggressive in 4G network coverage and subscribers growth.

40

We lead the mobile market in 13 states: Acre, Amazonas, Amapá, Bahia, Espírito Santo, Minas Gerais, Mato Grosso, Mato Grosso do Sul, Pará, Roraima, Rio Grande do Sul, Sergipe and São Paulo. TIM, a Brazilian telephone company and subsidiary of Telecom Italia lead the mobile market in six states: Alagoas, Ceará, Pernambuco, Paraná, Rio Grande do Norte and Santa Catarina. Oi leads mobile services in two states: Maranhão and Paraíba. Claro Brasil or Claro is a mobile operator controlled by the Mexican company America Móvil Group, and leads mobile service in six states: Distrito Federal, Goiás, Piauí, Rio de Janeiro, Rondônia and Tocantins (according to ANATEL, as of December 2017).

On the fixed front, the wireline and pay TV services reported net disconnections, according to Anatel. In broadband, market continued to expand mainly in ultra-broadband and fiber accesses. Our main competitors in fixed telecommunications services are Claro Brasil (which includes NET, Claro and Embratel) and Oi, which is stronger in the fixed services outside the State of São Paulo. TIM (subsidiary of Telecom Italia) has been offering its fixed broadband network ‘TIM Live’ in five cities. SKY, currently controlled by AT&T (expected sale to the Time Warner group), has pay TV and broadband services (LTE TDD 4G). In addition, we have competition from many regional service providers throughout the country.

Regulation of the Brazilian Telecommunications Industry

Our business, including the services we provide and the rates we charge, is materially affected by comprehensive regulation under the General Telecommunications Law and various administrative rules thereunder. We operate under a concession agreement that authorizes us to provide specified services and subjects us to certain obligations, according to the General Universal Service Targets Plan (Plano Geral de Metas de Universalização – PGMU), and the General Quality Targets Plan(Plano Geral de Metas de Qualidade – PGMQ).

ANATEL is the regulatory agency established by the General Telecommunications Law, and is administratively and financially independent from the Brazilian government. Any proposed regulation by ANATEL is subject to a period of public comment and, occasionally, public hearings, and its decisions may be challenged in Brazilian courts.

Concessions and Authorizations

In accordance with the General Telecommunications Law, concessions are licenses to provide telecommunications services granted under the public regime, while authorizations are licenses to provide telecommunications services granted under the private regime.

Companies that provide services under the public regime, known as the concessionaires, are subject to certain obligations as to quality of service, continuity of service, universality of service, network expansion and modernization.

A concession may only be granted pursuant to a public bidding process. As a result, regulatory provisions are included in the relevant concession agreements and the concessionaire is 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 the reversible assets from the concessionaire to the government authority upon termination of the concession. Another distinctive feature of public concessions is the right of the concessionaire to maintain economic and financial standards, which are calculated based on the rules set forth in our concession agreement and was designed based on a price cap model. The concession is granted for a fixed period of time and is generally renewable only once.

The companies that operate concessions under the public regime are Telefônica Brasil, Oi, Algar, Sercomtel and Claro (Claro for domestic and international long distance service). These companies provide fixed-line telecommunications services in Brazil that include local, intraregional, interregional and international long-distance services. All other telecommunications service providers, including the other companies authorized to provide fixed-line services in our concession region, operate pursuant to authorizations under the private regime.

41

Companies that provide services under the private regime, known as authorized companies, are not subject to the same requirements regarding continuity or universality of service; however, they may be subject to certain network expansion and quality of service requirements that are obligations set forth in their authorizations. Authorizations are granted for an indeterminate period of time. Under an authorization, the government does not guarantee to the authorized company an economic-financial equilibrium, as is the case under concessions.

An authorization is a license granted by ANATEL under the private regime, which may or may not be granted pursuant to a public bidding process, to the extent that the authorized company complies with the objective and subjective conditions deemed necessary for the rendering of the relevant type of telecommunication service in the private regime.

The General Telecommunications Law delegates to ANATEL the power to authorize private regime companies to provide local and intraregional long-distance services in each of the three fixed-line regions and to provide intraregional, interregional and international long-distance services throughout Brazil. ANATEL has already granted authorizations for companies to operate in Region III, our concession region. ANATEL has also granted other authorizations for companies to operate in other fixed-line regions and authorizations to provide intraregional, interregional and international long-distance services throughout Brazil competing with Claro, which operates under a long-distance fixed-line concession.

Concessionaires, including us, can also offer other telecommunications services in the private regime, which primarily include data transmission services, mobile services and Pay TV.

Obligations of Telecommunications Companies

Pursuant to the concessions and authorizations, we and other telecommunications service providers are subject to obligations concerning quality of service, network expansion and modernization. Telecommunication concessionaires are also subject to a set of special restrictions regarding the services they may offer, which are listed in the General Grants Plan(Plano Geral de Outorgas – PGO), and special obligations regarding network expansion and modernization contained in the PGMQ.

In 2001, a presidential decree published with the PGO increased the flexibility of telecommunications provider groups as fixed line concessionaires by allowing such providers to provide services in up to two of the three regions established by the PGO. Before this decree, telecommunications provider groups holding fixed-line concessions could offer fixed line services in only one region under the public regime.

In 2008, another presidential decree allowed concessionaries to operate outside their concession areas and unified sectors 31, 32 and 34. Thus, region III was comprised of sectors 31 and 33.

In December 2016, ANATEL held a public consultation relating to the new rules of the PGO containing an exclusive chapter aimed at verifying the migration of fixed telephony concessions for authorizations, in accordance with the new legal framework discussed in the Congress. The new regulation should be subject to extensive discussion in 2017 and its effects should only come after the approval of the new framework.

Any breach of telecommunications legislation or of any obligation set forth in concessions and authorizations may result in a fine of up to R$50 million.

Our main operations are regulated as follows:

·Fixed line voice services (local and long distance) under concession agreement in the state of São Paulo and under authorization agreement in the rest of the Brazilian territory. The concession was granted in 1998 by the Brazilian Government and renewed in December 2005 for 20 more years. It authorizes us to provide fixed-line telecommunications services in the state of São Paulo, except for a small area (Sector 33) and to place and manage public telephones in our concession area. We also provide fixed-wireless services throughout our concession area, for which the authorization was granted in 2001 by the Brazilian Government for the whole Brazilian territory;

42

·Mobile voice and broadband services, in all 26 states and the Federal District, under the personal mobile service (Serviço Móvel Pessoal), or SMP authorizations.

·Multimedia communication services, such as audio, data, voice and other sounds, images, texts and other information throughout Brazil. We operate under a nationwide SCM authorization, valid for an indefinite term;

·Pay TV service, throughout all regions of Brazil under the conditioned public service (Serviço de Acesso Condicionado), or SeAC authorization. We operate a SeAC authorization, which is valid for indefinite term; and

·Wholesale services, such as interconnection, governed by the interconnection agreements discussed under “—Operating Agreements—Interconnection Agreements,” industrial dedicated line (Exploração Industrial de Linha Dedicada – EILD), which are regulated by ANATEL Resolution No. 590, dated May 15, 2012 and Mobile Virtual Network Operator, or MVNO agreements described under “—Operating Agreements—MVNO Agreements.”

We set forth below details of the concession, authorizations, licenses and regulations that regulate our operations.

Quality Regulations in Brazil

The quality of service on Fixed Broadband (SCM), Mobile Telephony (SMP), Fixed Telephony (STFC) and Pay TV (STVA) is monitored by ANATEL through the operational and network performance indicators for telecom operators. Each indicator has an associated target, which must be achieved by the service provider on a monthly basis in each geographic area that it operates.

The indicators, as well as their respective methods of collection, calculation and other quality requirements, are defined in specific regulations published by ANATEL. Fixed broadband, mobile telephony, fixed telephony and Pay TV indicators are established in the Quality Management Regulations, respectively, Resolutions 574/2011, 575/2011, 605/2012 and 411/2005.

For cases in which there are indications of performance or conduct other than those established in the regulations, Anatel establishes a noncompliance process called Procedure for Determination of Non-Compliance to Obligations (Procedimento de Apuração de Descumprimento deObrigações – PADO) in detriment to the provider. When applicable, the sanctions may include warning, fine, temporary suspension, obligation demand, expiration or declaration of unworthiness.

With the objective of correcting deficiencies that may be found in the quality of service provision, ANATEL may adopt additional measures determining the execution of a plan of action for correcting conduct or improving the performance of providers, among other reasons.

On November 2017, the agency published a new public consultation on the Proposal for a new Regulation on the Quality of Telecommunications Services, which will be receiving contributions until March 2018.

Fixed Services

Our Concession Agreement

We are authorized to provide fixed line services to render local and domestic long-distance calls originating in Region III, which comprises the state of São Paulo, except for Sector 33, established in the PGO.

The current concession agreement that is valid through December 31, 2025 was reviewed in 2006 and 2011. According to Resolution Number 678/2017 a new revision must be made on December 31, 2020. Until then, the 2011 contract remains valid.

43

Other regulations have been adopted to revise certain aspects of our concession. On June 30, 2011, ANATEL determined the new basis of calculation of the biannual concession fees. Every two years, during the new 20-year period of our concession, we are required to pay a renewal fee, which amounts to 2% of the total revenue in the previous year, calculated based on the revenues and social contribution of fixed line basic and alternative plans. The most recent payment of this biennial fee was made on April 28, 2017, based on 2016 revenue. The next payment is therefore scheduled for 2019 based on 2018 revenue. See Note 1 to our Consolidated Financial Statements.

In addition, the Brazilian government published Decree No. 7,512 which proposed the General Plan for the Universalization of Fixed Telephone Services under the Public Regime (Plano Geral de Metas para a Universalização do Serviço Telefônico Fixo Comutado Prestado no Regime Publico – PGMU III).  It set forth new targets for public pay phones (Telefone de Uso Público) availability in rural and low-income areas and targets related to low-income fixed line services (Acesso Individual Classe Especial – AICE).

On June 27, 2014, ANATEL held a public consultation for the PGMU. Since there was no mutual agreement between ANATEL and the operators for the signature of the 2015 concession agreement contracts, the new version of the PGMU was also delayed. At the time of release of this report, the presidential decree concerning the expected PGMU revision related to 2015 (PGMU IV) has not been published.

According to our concession agreements, all assets owned by us which are indispensable to the provision of the services described in such agreements are considered “reversible assets”. As per ANATEL’s recent interpretation of the current regulation these assets will be automatically returned to ANATEL upon the expiration of the concession agreements, in accordance to the regulation in force at that time, and would not be available to creditors in the event of insolvency, bankruptcy or similar events. With discussions relating to a new regulatory framework under way, this rule could no longer exist in light of the possibility of transforming concessions into authorizations.

On April 8, 2008, we entered into an amendment to the concession agreement to substitute the obligation to install telecommunications service posts with an obligation to roll out broadband network infrastructure throughout the municipalities serviced by such concessionaires. This amendment could be extended with the approval of the counterparties of the new regulatory framework.

On October 23, 2012, ANATEL published Resolution No. 598 addressing the criteria and procedures for the execution and control of obligations related to the universalization of services. The resolution sets deadlines to meet access requests, sets targets for the expansion of the public telephone plant, establishes a list of agencies that can request access to their location, reviews the deadline for proposing service plans and establishes obligations disclosure.

Currently, the Brazilian Congress is discussing a new regulatory framework for telecommunications that is expected to affect our concession agreements. The new regulatory framework contains several changes to the existing regime, which primarily include, among other things, the immediate replacement of the current concession-based regime for an authorization-based regime, changes in the standards for the use of frequencies and Brazilian orbital position, as well as terms relating to the transfer of reversible assets to telecommunication companies in exchange for investments in the fixed broadband infrastructure by such companies.

For information about regulations affecting rates we are able to charge under our concession agreements, see

“—Rates, Taxes and Billing.”

Obligations and Restrictions on concessionaires to provide fixed line service under the public regime

We and the other concessionaires are subject to the General Universal Service Targets Plan (Plano Geral de Metas de Universalização – PGMU), which requires that concessionaires undertake certain network expansion activities with respect to fixed-line services. The timing for network expansion is revised by ANATEL from time to time.  If any given concessionaire does not fulfill its obligations under the PGMU, ANATEL may impose various monetary penalties and such concessionaire may lose its license if ANATEL determines that it will be unable to provide basic services under the Plan.

44

Concessionaires are also subject to certain restrictions on alliances, joint ventures, mergers and acquisitions, including:

·a prohibition on holding more than 20% of the voting shares of the facto control in any other concessionaire, according to ANATEL Resolution No. 101; and

·a prohibition on concessionaires to provide fixed-line telecommunications services through related companies.

Fixed line service under the private regime

In 2002, we began providing local and interregional services in Regions I and II and Sector 33 of Region III, and international long-distance services in Regions I, II and III, which constitute regions in Brazil that are outside of our public regime concession area.

Public Telephone Regulation

On June 30, 2014, ANATEL published the new Public Telephone Regulation. Among the new rules, it opened up the possibility of advertising on the public telephones and the possibility of alternative payment modalities.

In 2016, ANATEL extinguished the Standard for the Certification and Homologation of the Inductive Card. Instead, a list of Technical Requirements for Telecommunications Products was issued.

Mobile Services

In October 2016, ANATEL approved new spectrum use regulations, which facilitates access to radio frequencies and generates efficiency in its use, due to the simplification of procedures and necessary documentation. The regulation also alters spectrum pricing (for non-bidding grants), rules for extending use authorization and new rules for frequency use on a secondary basis prior to primary use.

Mobile Service Licenses (SMP)

Our authorizations to provide mobile services throughout Brazil consist of two licenses—one to provide mobile telecommunications services, and another to use the respective frequency spectrum for a period of 15 years. The frequency license is renewable for an additional 15-year period upon payment of 2% of net operating revenues over usage charges in the region described above, every two years for the duration of the extension period. In the 15th year, the Company will pay 1% of the aforementioned amount.

Our SMP authorizations include the right to provide mobile services for an unlimited period of time but restrict the right to use the spectrum according to the schedules listed in the radiofrequencies authorizations. The table below sets forth our current SMP authorizations, their locations, band and spectrums, date of issuance or renewal and date of expiration:

In 2013, we changed the terms of our authorization regarding Band “L” (1.9 GHz) in certain locations, adapting their blocks of frequencies to 2.1 GHz and aligning them with the band “J” (3G) which provides a more efficient use of the spectrum. The alignment has not occurred in the following areas:  Northeast, with the exception of Bahia and Sergipe; Pelotas, Morro Redondo, Capão do Leão and Turuçu, in Rio Grande do Sul; Buriti Alegre, Cachoeira Dourada, Inaciolândia, Itumbiara, Paranaiguara and São Simão, in Goiás; Altinópolis, Aramina, Batatais, Brodosqui, Buritizal, Cajuru, Cássia dos Coqueiros, Colômbia, Franca, Guaíra, Guará, Ipuã, Ituverava, Jardinópolis, Miguelópolis, Morro Agudo, Nuporanga, Orlândia, Ribeirão Corrente, Sales de Oliveira, Santa Cruz da Esperança, Santo Antônio da Alegria and São Joaquim da Barra in São Paulo; and Paranaíba in Mato Grosso do Sul. This change is foreseen in the bidding document No 001/2007. We do not have band “L” in the states of Amazonas, Roraima, Amapá, Pará and Maranhão and in the cities of Londrina and Tamarana, Paraná.

47

In 2012, Telefonica acquired 40MHz on the 2.5GHz to 2.69GHz frequencies for the amount of R$ 1.05 billion. To complete the coverage requirements we had the obligation of implementing 4G coverage in 1,094 cities by December 31, 2017. However, we made 4G services available in over 2,600 municipalities by that date. To achieve these goals, Telefonica has deployed and continues to deploy 4G coverage in such municipalities and serves its customers through the use of its own network or by agreement of RAN-sharing approved by ANATEL. Verification of compliance with these targets will be controlled by the agency.

The remaining coverage commitments in cities with less than 30,000 inhabitants may be fulfilled with 3G or superior technology operating in any frequency band, respecting the following schedule:

·by December 31, 2018: another 117 cities; and

·by December 31, 2019: 156 more cities.

To complete the 450 MHz frequency requirements we had the obligation to meet voice and data demand in remote rural areas. As a commitment, we are required to provide infrastructure and service operating in any frequency band in rural areas in the states of Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe, and countryside of São Paulo, for a total of 2,556 municipalities. In these areas, we are also required to provide free broadband to schools located in rural areas.

In December 2015, ANATEL and CADE approved the agreement between Telefônica Brasil, TIM and Oi for the construction, implementation and mutual assignment of network tools for supporting the Personal Mobile Service (voice and broadband) in the 2.5 GHz band, in order to make compliance with the scope of commitments between 2015 and 2017 and the expansion of 4G coverage, considering municipalities with a population over 30 thousand inhabitants. The operation involves the search for more efficiency of resources application of rationality and presenting a solution to the urban planning and environmental restrictions on the deployment of the new radio base stations (cell sites).

Regarding the 700MHz spectrum, ANATEL has allocated the band for the provision of fixed, mobile and broadband services. On September 30, 2014 we acquired 20 MHz (10+10 MHz) with nationwide coverage, for R$1.92 billion, at the minimum price, plus R$904 million for the band cleaning (migration of broadcasters that currently occupy the band and interference management). According to the auction rules, the winning bidders is responsible for financing and managing the band cleaning process.

In January 2016, the Ministry of Communications (now Ministry of Science, Technology, Innovations and Communications) published a new schedule for the Analog TV Switch Off, postponing the usage of the 700 MHz frequency for telecommunications in some major Brazilian cities. According to the schedule and its further revisions, 11 cities had its Analog TV services turned off in 2016, including Rio Verde (GO) and Brasília (DF). In 2017 the switch off was completed in over 404 cities. In 2018 the analog switch off is expected to be completed in 1124 cities distributed in 24 states. The switch off for the remaining 4244 cities is set for 2023, though the activation of LTE in these cities does not require the switch off to be completed.

In December 2015, ANATEL auctioned the remaining spectrum lots in the 1800 MHz, 1900 MHz and 2500 MHz bands, from which Telefônica acquired seven lots of 2.5 GHz frequency band offering a total of R$ 185.4 million. These lots are associated to six different States, in the capital cities of the States of São Paulo, Rio de Janeiro, Porto Alegre, Florianópolis, and Palmas, and one countryside city of the State of Mato Grosso do Sul. Such frequencies are already being used for the provision of mobile broadband service on 4G.

Multimedia Communication Services (SCM)

Our multimedia services include broadband in several technologies, including fiber UBB services.

Obligation to provide fixed broadband access

We have assumed in the past the obligation to provide free Internet access to public schools in the area comprising in our concession area during the term of the concession agreement (until 2025). The number of schools for which we should provide broadband is determined by the school census provided by the National Education Ministry, which is published on a yearly basis or sometimes in longer intervals. Our obligation targets are adjusted according to the latest census released.

Pay TV services

Regulations for Pay TV Services– SeAC

We are authorized to provide Pay TV Services – SeAC. On September 12, 2011, the Brazilian Congress adopted Law 12,485/2011 as a result of Bill 116, which establishes a new legal framework for audiovisual communication with restricted access. This law opens the Pay TV market by enabling telecom operators to offer audiovisual content to subscribers through their networks, creating a new service called Pay TV Services (Serviço de Acesso Condicionado - SeAC). The absence of restrictions on foreign capital to be invested in Pay TV providers, as well as the elimination of restrictions for the provision of other telecommunications services through fixed line concession, allow us to provide Pay TV services, as well as other telecommunication services previously limited under the General Telecommunications Law.

Pursuant to Law 12,485/2011, the Pay TV service has replaced current cable subscription TV services, subscription TV, MMDS and DTH, giving power to ANATEL to regulate the Pay TV service. As a result of this law, ANATEL introduced in December 2011 the proposed regulations for Pay TV services through Public Consultation No. 65/2011, including license grants, installation and licensing of stations and mandatory distribution programming channels. The Public Consultation was finalized on February 2, 2012 and resulted in Resolution No. 581, issued by ANATEL on March 28, 2012, as well as the new Authorization Terms of the SeAC.

Law No. 12,485/2011 also established an annual payment to Condecine (Contribuição para o Desenvolvimento da Indústria Cinematográfica) to be made by providers of telecommunication services and amended Law No. 5,070/1966 by revising the amount due as Inspection Fee (Taxa de Fiscalização de Funcionamento) for telecommunication stations from 45% to 33% of the Installation Fee (Taxa de Fiscalização de Instalação). The amount due to Condecine is approximately 12% of the Installation Fee for telecommunication services and must be paid by March 31 every year.

As a result of Law No. 12,485/2011, the National Cinema Agency (Agência Nacional do Cinema – ANCINE) issued one public consultation by the end of 2011 and one public consultation in 2012 to regulate the registration of economic agents. In 2013, we had our licenses adapted to the new regulation and was recognized as an economic agent by ANCINE. In 2014, ANCINE recognized Telefônica Brasil S.A. as a Pay TV content packer.

In March 2016, ANATEL published a Public Consultation to change the regulation for Pay TV access services (SeAC). The proposal brought new rules for the isonomic treatment of open channels, transfer of grants, for the transfer of control between pay-TV companies, and the obligation to load channel accessibility resources, among other aspects. The new regulation is still under discussion within ANATEL.

Interconnection Fees

In accordance with ANATEL regulations, we must charge fees to the other telecommunications service providers based on the following:

·Fee for the use of our local fixed service network (TU-RL) - we charge local service providers an interconnection fee for every minute used in connection with a call that either originates or terminates within our local network, with the exception of calls between other providers of local fixed service, for which a fee is not charged;

·Fee for the use of our fixed service long-distance network (TU-RIU) - we charge long distance service providers an interconnection fee on a per-minute basis only when the interconnection access to our long-distance network is in use;

·Fee for the use of mobile network (MTR) – we charge mobile service providers an interconnection fee on a per-minute basis only when the interconnection access to our mobile network is in use;

49

·Fee for the use of leased lines by another service provider (EILD). We also lease transmission lines, certain infrastructure and other equipment to other providers of telecommunications services.

Fixed Service

In July 2005, ANATEL published new rules regarding interconnection. The main changes are: (i) an obligation to have a public offering of interconnection for all services, besides interconnections fees between providers of fixed and mobile telephone services; (ii) an offer of interconnections for Internet backbone providers; (iii) establishment of criteria for the treatment of fraudulent calls; and (iv) reduction of service times for interconnection requests.

In 2006, we completed the implementation of the interconnection with the mobile service providers in regions with heavier traffic, assuring the proper billing for such calls. This movement reduced the interconnection costs.

In 2007, ANATEL published a new version of Fixed Network Compensation Regulation that changed the rules to determine the interconnection fees. Local and long-distance rates that were set at all times became variable according to the rules of public service tariffs. A 20% increase was applied to tariffs of mobile service operators without significant market power in their regions.

On May 7, 2012, Resolution No. 588/12 was published determining the following:

·A maximum of two minutes of interconnection should be paid for the use of the local network on reduced hours;

·The reduction of interconnection fees from domestic and international long distance calls by 30% of the value of the local fixed service network interconnection fee (TU-RL) and the reduction of 25% and 20% by December 2012 of the value of the long distance network interconnection tariffs (TU-RIU);

·The remuneration between networks will not occur until this traffic imbalance is greater than 75% compared to 25%; and

·The partial Bill & Keep by December 31, 2013 and full Bill & Keep by December 31, 2014.

On July 1, 2014, ANATEL established gradual decreases in fixed service network interconnection fees (TU-RL), based on a cost model for the years 2016, 2017, 2018 and 2019, as described under “Item 3. Key Information—D. Risk Factors—Risks Relating to the Brazilian Telecommunications Industry and Us—Our results of operations may be negatively affected by the application of the Fixed Commuted Telephone Service (Serviço de Telefonia Fixa Comutada – STFC) rules relating to fixed telephone service and the Personal Mobile Service (Serviço Móvel Pessoal – SMP), rules relating to mobile services.”

In December 2016, ANATEL held a public consultation to discuss a new interconnection regulation (RGI). The new document aims to solve the large amount of disputes in the agreements for voice and data traffic among companies. ANATEL has proposed that in cases of default the cut in the provision of interconnection could be done without the regulator’s authorization. In addition, the new document aims to establish a list of prohibited practices in interconnection relationships and to make the interconnection technology neutral. The new rules should be published during 2018.

Mobile service

In November 2009, ANATEL unified the licenses of all mobile operators, resulting in the consolidation of interconnection fees, reducing the number of fees for the use of mobile network from 2 to 1.

On December 2, 2013, Act no. 7,272 was published, establishing the MTR reference values for providers determined to be a Significant Market Power (PMS), which became effective on February 24, 2014. On August 28, 2014, Act no. 7,310 replaced the reference values previously set out in Act no. 7,272.

50

On July 1, 2014, ANATEL established gradual decreases in mobile interconnection fees (MTR), based on a cost model for the years 2016, 2017, 2018 and 2019, as described in “Item 3. Key Information—D. Risk Factors—Risks Relating to the Brazilian Telecommunications Industry and Us—Our results of operations may be negatively affected by the application of the Fixed Commuted Telephone Service (Serviço de Telefonia Fixa Comutada – STFC) rules relating to fixed telephone service and the Personal Mobile Service (Serviço Móvel Pessoal – SMP) rules relating to mobile services.”

In addition, the General Competition Plan (“Plano Geral de Metas de Competição – PGMC) determined that the in the relationship among PMS and non-PMS providers in the mobile network, the interconnection fee should be paid only when the traffic out of a network in a given direction is greater than 80% of the total traffic exchanged until February 23, 2015; and 60% of the total traffic exchanged from February 24, 2015 to February 23, 2016. Since February 24, 2016, the MTR is owed to the mobile service provider when its network is used to originate or terminate calls (full billing). 

In February 2015, after promoting a Public Consultation, ANATEL modified the rules regarding the interconnection fee to be paid of the outbound traffic:

·Up to February 23, 2015: 80% / 20%

·From February 24, 2015 to February 23, 2016: 75% / 25%

·From February 24, 2016 to February 23, 2017: 65% / 35%

·From February 24, 2017 to February 23, 2018: 55% / 45%

·From February 24, 2018 to February 23, 2019: 50% / 50%

·From February 24, 2019 onwards: Full Billing.

Since this change, TIM and Claro have filled a lawsuit to suspend the modification of the rules concerning the tariff reduction on the fixed-mobile introduced by Resolution 649. This lawsuit remains under way.

TU-RL and TU-RIU

On May 18, 2014, the proposed standards were approved for setting maximum values of fixed interconnection fees and for the values of mobile interconnection, based on Cost Models. In addition, values for fixed and mobile interconnection were published through the acts: No. 6210 for TU-RL and TU-RIU and No. 6211 for MTR.

For fixed and mobile termination fees, ANATEL’s decision established values for 2018 based on a bottom-up cost model. For 2016 and 2017 intermediate values were adopted.

EILD

On May 18, 2014, ANATEL approved the proposed standard for setting maximum values of Industrial Dedicated Line (EILD), based on Cost Models. Values for EILD were published through Act No. 6212, which contains a single reference table which is valid from 2016 until 2020. In addition, the general competition plan requires companies with significant market power to present a public offer every six months informing standard commercial conditions, which is subject to approval by ANATEL.

Mobile Virtual Network Operator (MVNO)

In 2001, ANATEL approved rules for companies to be licensed as MVNOs. In 2016, ANATEL authorized MVNO companies to be affiliates of other certain network operators, and for that reason we have signed agreements with companies authorized to operate as an MVNO in Brazil.

51

Internet and Related Services in Brazil

In Brazil, Internet service providers, or ISPs, are deemed to be suppliers of value-added services and not telecommunications service providers. ANATEL requires SCM operators to act as carriers of third-party internet service providers.

Exemptions for telecommunications infrastructure

In connection with the national plan entitled “Plano Brasil Maior”, instituted to promote the Brazilian technology industry and foreign trade, the Brazilian Government established the special tax regime for the taxation of national broadband plans (Regime Especial de Tributação para o Plano Nacional de Banda Larga – RePNBL). This regime provides tax exemptions for telecommunications companies for broadband network expansions.

Another initiative set forth by “Plano Brasil Maior” and approved by the government on May 5, 2014, was the establishment of exemptions for machine-to-machine services. The initiative reductions on the two taxation rates that compose the Telecommunications Inspections Fund (FISTEL). The Installation Inspection Rate (TFI), which is charged for each enabled chipset, decreased from R$26.83 in 2013 to R$5.68 in 2014, whereas the Operations Inspection Rate (TFF), paid every year for each chipset held by a Brazilian operator, decreased from R$12.40 in 2013 to R$1.89 in 2014.

On January 14, 2015, the Ministry of Communications published a decree that reduces national technology requirement in the aforementioned RePNBL. Some requirements were reviewed in mobile and electrical networks in order to accelerate projects and attract more investments.

The deadline for submission of projects for the RePNBL program was June 30, 2015. A total of 1,167 projects were approved, amounting to investments in the order of R$15.1 billion and reaching 3,699 cities in all Brazilian states. We had 143 projects authorized, totaling an amount of approximately R$4.3 billion in investments.

Civil Rights Framework for the Internet

On April 23, 2014, at the opening of NetMundial, former President Dilma Rousseff approved the Civil Rights Framework for the Internet (“Marco Civil da Internet”), which was enacted as Law 12,965/2014. The act adopts strict Net Neutrality rules that guarantees equality of treatment for data traffic in the network and preserves the business model of Brazilian broadband offered in packages with different speeds. After three public consultations released by CGI.br (the Brazilian Internet Steering Committee), the Ministry of Justice and ANATEL, the Brazilian government published Decree 8,711/2016, which regulates the law. It establishes regulation for Net Neutrality and mechanisms to protect the data stored by service and application providers, as well as determining the circumstances in which data can be obtained by the public administration.

Personal Data Protection

In June 2016, the Brazilian House of Representatives put into consultation a draft of law regarding the Personal Data Protection. The original text of this law is based on the European Union’s Directives on Data Protection, and as such, imposes restrictive rules on the express consent to process personal data, international data transfer, processing of sensitive data, among others. The proposed legislation is still under discussion within the House of Representatives.

Resolutions Published

A series of new regulations, published by ANATEL as well as other regulatory bodies in Brazil, became effective in 2017. The most relevant among these regulations were:

Other Regulatory Matters

TAC

On October 27, 2016, ANATEL’s Board of Directors approved a Conduct Adjustment Term (TAC) for the Company, subject to the approval of the Court of Auditors of the Union (TCU). This TAC aims to settle certain fines currently imposed by ANATEL as long as the Company commits to invest in certain specific projects. Among these projects, the Company will need to make investments to improve the quality of services provided and provide fixed broadband access through FTTH to about 100 municipalities in and outside the State of São Paulo over a 4-year period.

54

In September 2017, after having held TAC under analysis for months, TCU unanimously decided that there were no obstacles preventing ANATEL from signing the agreement. TCU established, however, that prior to the celebration of the contract, the agency must comply with certain determinations and recommendations imposed by the court. The technical area of ANATEL worked on the necessary adjustments during the last months of 2017, and the expectation is that the new version will be submitted and approved by ANATEL’s Directing Council during 2018, after which TCU will make a new summary evaluation of the conditions, thus allowing the agreement to enter into force.

Fixed Broadband Cap

In April 2016, discussions on the adoption of the fixed broadband cap model gained prominence the in Brazilian media. Entities representing consumers and government agencies reacted to the strategy of some telecommunications companies, including Vivo, which foresaw the service limitation due to the depletion of the consumption cap.

In response to public disapproval, ANATEL published a preliminary order (“cautelar”) prohibiting the main telecommunication companies to implement speed limitation or suspension of the fixed broadband service due to full consumption of the cap, until further measures are put in place to provide the customer with information and tools to control consumption.

In November 2016, ANATEL published on its website a questionnaire about the fixed broadband cap model. The consultation was open to any citizen to respond. At the same time, this same questionnaire was sent to a list of 150 specialized entities, including universities, courts, consumer protection bodies, operators (including Telefonica) and former agency counselors. ANATEL is still analyzing the responses to this consultation.

Regulation for Reference Offers of Wholesale Products Approval

ANATEL launched, in December 2016, a Public Consultation for the Regulation that set price reference for the wholesale products. The proposal aims to determine that ANATEL’s Cost Model should be the only source of information for the validation of these prices. ANATEL is still analyzing the responses and the new regulation is forecasted to be published in 2018.

Productivity Factor

In September 2017, ANATEL approved the new methodology for calculating the Productivity Factor (X Factor) of fixed telephony service. The new regulation uses the cost model to segregate revenues and costs for services. In the new formula, although gains with retail broadband were ruled out, the methodology continues to consider the productivity gains of the fixed voice authorization. Telefonica is arguing that the calculation should focus only on the productivity of the fixed voice concession.

C.    Organizational Structure

On December 31, 2017, 94.31% of our voting shares were controlled by three major shareholders: SP Telecomunicações Participações Ltda. with 51.46%, Telefónica S.A. with 34.67% and Telefônica Latinoamérica Holding, S.L. with 8.18%. Telefônica Latinoamérica Holding, S.L., or Telefônica Latinoamérica, is the controlling shareholder of SP Telecomunicações S.A., or SP Telecomunicações. Telefónica Latinoamérica is a wholly owned subsidiary of Telefónica S.A.. Therefore, Telefónica S.A. was the beneficial owner of 94.47% of our voting shares, as Telefónica Chile S.A., holder of 0.16% of our voting shares, is also a wholly owned subsidiary of Telefónica S.A.. See “Item 7. Major Shareholders and Related Party Transactions—A. Major Shareholders.”

56

The following information is disclosed pursuant to Section 13(r). None of these activities involved U.S. affiliates of Telefónica or the Company.

Roaming Agreements with Iranian Operators

Various subsidiaries of our controlling shareholder, Telefónica, have entered into roaming agreements with Iranian telecommunication companies. Pursuant to such roaming agreements these subsidiaries’ customers are able to roam in the particular Iranian network (outbound roaming) and customers of such Iranian operators are able to roam in the network of Telefónica’s relevant subsidiary (inbound roaming). For outbound roaming, these subsidiaries pay the relevant Iranian operator roaming fees for use of its network by our customers, and for inbound roaming the Iranian operator pays the relevant subsidiary roaming fees for use of our network by its customers.

We have a roaming agreement with MTN Irancell. During 2017, we recorded 43.87 euros in roaming revenues and 5,445.94 euros of expenses payable to Irancell under this agreement. In addition, as part of the Telefónica group, we adhere to the roaming agreements with Telefónica’s subsidiaries described below.

Telefónica’s subsidiaries were party to the following roaming agreements with Iranian telecommunication companies in 2017:

(1)Telefónica Móviles España (“TME”), Telefónica’s Spanish directly wholly-owned subsidiary, has respective roaming agreements with (i) Mobile Telecommunication Company of Iran (“MTCI”), (ii) MTN Irancell (“Irancell”), (iii) Taliya (“Taliya”) and (iv) Telecommunications Kish Co. (“TKC”). During 2017, TME recorded the following revenues related to these roaming agreements: (i) 40,450.45 euros from MTCI, (ii) 13,086.49 euros from Irancell, (iii) no revenues from Taliya and (iv) no revenues from TKC.

TME also holds Roaming Hub through its 55% directly-owned subsidiary, Link2One, a.e.i.e. (“L2O”). Under the related agreement, L2O provides a roaming hub service to Irancell enabling the latter to maintain a relationship with other members of the hub. Some members of the hub are also entities of the Telefónica Group. During 2017 L2O recorded revenues of 48,283.42 euros from Irancell.

(2)Telefónica Germany GmbH & Co. OHG (“TG”), Telefónica’s German 69.22% indirectly-owned subsidiary, has respective roaming agreements with (i) MTCI and (ii) Irancell. During 2017, TG recorded revenues of (i) 100,501.29 euros from MTCI and (ii) 997.08 euros from Irancell.

(3)Telefónica UK Ltd (“TUK”), Telefónica’s English directly wholly-owned subsidiary, has respective roaming agreements with (i) MTCI and (ii) Irancell. During 2017 TUK recorded (i) no revenues from MTCI and (ii) 2,817.33 euros from Irancell.

(4)Telefónica Argentina, S.A. and Telefónica Móviles Argentina, S.A. (together “TA”), Telefónica’s Argentinean directly and indirectly wholly-owned subsidiaries, have a roaming agreement with Irancell. During 2017 TA recorded 15.38 euros in roaming revenues under this agreement.

(5)Pegaso Comunicaciones y Sistemas, S.A. de C.V. (“PCS”), Telefónica’s Mexican directly wholly-owned subsidiary, has a roaming agreement with Irancell. During 2017 PCS recorded 14.53 euros in roaming revenues under this agreement.

(7)Colombia Telecomunicaciones, S.A. ESP (“ColTel”), Telefónica’s Colombian 67.50% directly and indirectly-owned subsidiary, holds a roaming hub through L2O. L2O, in turn, provides a roaming hub service to Irancell enabling the latter to maintain a relationship with other members of the hub. During 2017 ColTel recorded 11.26 euros in roaming revenues under this roaming hub service.

57

The net profit recorded by Telefónica’s subsidiaries pursuant to these agreements did not exceed the related revenues recorded thereunder.

The purpose of all of these agreements is to provide the Telefónica group’s customers with coverage in areas where the group does not own networks. For that purpose, Telefónica’s subsidiaries intend to continue maintaining these agreements.

International Carrier Agreement with Iran

Telefónica de España has an international carrier agreement with Telecommunication Company of Iran.

Pursuant to this agreement, both companies interconnect their networks to allow international exchange of telephone traffic. Telefónica de España recorded 7,992.64 euros in revenues under this agreement in 2017. The net profit recorded by Telefónica de España pursuant to this agreement did not exceed such revenues.

The purpose of this agreement is to allow exchange of international telephone traffic. Consequently, Telefónica intends to continue maintaining this agreement.

D.    Property, Plant and Equipment

On December 31, 2017, we had fixed and mobile operations in 2,905 properties, 1,470 of which we own, of which 127 are administrative buildings. Besides that, we have entered into standard leasing agreements to rent the remaining properties, under which 119 administrative areas, 10 kiosks and 292 retail stores are leased.

Our main physical properties for providing fixed line telephone services involve the segments of switching (public switching telephone network, or PSTN), transmission (optic and wireless systems), data communication (multiplex devices, IP network), infrastructure (energy systems and air conditioning) and external network (fiber optic and metallic cables), which are distributed in many buildings throughout the state of São Paulo and in the main cities outside the state of São Paulo. Some of these buildings are also used for administrative and commercial operations.

Our main physical property for mobile services consists of transmission equipment, switching equipment, base stations, and other communication devices, such as voicemail, prepaid service, short message service, home location registers, signaling transfer point, packet data switching network and gateways. All switches, cellular sites, administrative buildings, administrative facilities, warehouses and stores are insured against damages for operation risks.

Pursuant to Brazilian legal procedures, liens have been attached to several properties pending the outcome of various legal proceedings to which we are a party. See “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings.”  In addition, certain of our properties are still pending the applicable licenses and approvals from the local fire departments.

We are constantly making improvements to our facilities and network to meet customer demand and to improve the level of services we offer our clients.

On December 31, 2017, the net book value of our property, plant and equipment amounted R$33.2 billion (R$31.9 billion on December 31, 2016), which included reversible assets in the amount of R$8.7 billion.

58

Environmental Matters

Brazilian Federal, State and Municipal legislation provide for the control and protection of the environment. These laws govern the appropriate use of natural resources, control of atmospheric emissions and noise, treatment of effluents, handling and final disposal of hazardous materials, amongst others.

Under these laws, certain environmental licenses must be secured prior to the construction, installation, expansion and operation of facilities that use natural resources or that may pollute the environment, including those related to installation and operation of radio/cell stations and antennas. According the stage of the project, the environmental licenses may be: (1) a preliminary license, which approves the location and design of the project and must be obtained in the early stages of the project or activity to certify its environmental feasibility; (2) an installation license, which authorizes the installation of the project or activity in accordance with the specifications set forth in approved plans, programs and projects; or (3) an operation license, which authorizes commencement of operations once the conditions for compliance with the preliminary and installation licenses are met, and may impose additional conditions applicable to the project’s operations.

Besides environmental licensing, other environmental regulations may affect our operations, such as, among other matters, regulations related to emissions into the air, soil and water, take-back systems, recycling and waste management, protection and preservation of fauna, flora and other features of the ecosystem, water use, interference with areas of cultural and historical relevance and with Conservation Units (UCs) or their surroundings, Permanent Preservation Areas (APPs) and contaminated areas.

Regarding the last subject matter, in accordance with the Environmental National Policy (Law No. 6,938/1981), the owner of a real estate property located in a contaminated area may be compelled by the relevant environmental agency to clean up the area, regardless of fault and the damage causes. Environmental authorities have been adopting an increasingly stringent position in connection with the handling of contaminated areas, including the creation of environmental standards to preserve the quality of land and underground water. Non-compliance with guidelines set by the relevant environmental and health authorities with respect to surveys and analyses of potentially contaminated areas or the exposure of persons to toxic fumes or residues may result in administrative and legal penalties for the developments and their management. We perform periodic environmental investigations to assess any possible liability with respect to contamination of soil.

We are subject to administrative review of our activities and corporations found to be in violation of these administrative environmental regulations can be fined up to R$50 million, have their operations suspended, be barred from entering into certain types of government contracts, be required to repair or provide indemnification in respect of any environmental damages they cause, be required to suspend tax benefits and incentives, among others.

In Brazil, violating environmental rules or regulations may result in civil, administrative or criminal liability. With respect to civil liability, Brazilian environmental laws adopt a standard of unlimited strict, several and joint liability in determining the obligation to remediate damages caused to the environment. In addition, Brazilian courts may pierce the corporate veil when and if it poses an obstacle to the full recovery of environmental damages.

We have a series of systems in place to protect our networks and operations from environmental damage.

Additionally, we have systems in place for the proper disposal of batteries and oil, in our construction operations and to address other environmental issues that may arise in the operation and maintenance of our properties. In 51 cities (that cover more than 40% of our clients) we have a certified Environmental Management System that meets ISO14.001 requirements since 2016. We also maintain the control of radio frequency energy levels transmitted by our antennas, in accordance with current legislation.  The energy consumption of our network infrastructure is very high and as a result we have implemented energy efficient technologies in order to reduce consumption and meet greenhouse gas emission reduction targets. We have also invested in clean energy as the source of our energy consumption, reaching the amount of 25% currently consumed from this type of source with targets to reach 50% until 2020 and 100% until 2030.

59

Also, to comply with Brazilian Federal regulations, (National Waste Policy - Law 12,305/10), we were the first telecommunications company in Brazil to offer collection points at all of our stores for old mobile phones, accessories and batteries, where customers and other individuals can dispose of their used equipment ensuring proper disposal of these materials. At fixed line telecom business, we directly pick up equipment that is defective from customers or once the contract Ends. These materials underwent triage and can be refurbished to be used again with full technical capacity and layout conditions. Through an online portal on our website, customers can schedule pick-ups of equipment that they no longer use. These processes ensure that more than 98% of our electronic waste is recycled.

Moreover, we must emphasize that we perform periodic environmental investigations to assess any possible liability with respect to contamination of soil and groundwater. Currently, we are executing remediation measures in the following units located at the Municipality of São Paulo: (i) Ibirapuera; (ii) Brooklin; (iii) Santo Amaro; (iv) Palmeira.

ITEM 5.        OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A.    Operating Results

The following discussion should be read in conjunction with our consolidated financial statements and accompanying notes and other information appearing elsewhere in this annual report and in conjunction with the financial information included under “Item 3. Key Information—A. Selected Financial Data.” We prepared our consolidated financial statements included in this annual report in accordance with IFRS.

Overview

Our results of operations are principally affected by the following key factors.

Brazilian Economic Environment

The Brazilian economy has experienced varying rates of growth this decade. According to IBGE (Instituto Brasileiro de Geografia e Estatística), the Brazilian GDP decreased by 3.5% in 2016, after the same decrease of 3.5% registered in 2015. According to market data, in 2017, the Brazilian GDP grew approximately 1%.

Consumer prices, as measured by the IPCA, increased 2.95% in 2017. Accordingly, growth in consumer prices stood below the lower limit of inflation target band established by the Central Bank of 4.5% +/- 1.5%. In 2015 and 2016, the increases in IPCA were 10.7% and 6.3%, respectively. Inflation, as measured by the Brazilian general price index (Índice Geral de Preços - Disponibilidade Interna), or the IGP-DI, calculated by the FGV, which includes wholesale, retail and home-building prices, increased 10.7% and 7.2% in 2015 and 2016, respectively. In 2017, the IGP-DI decreased 0.42%.

As inflation rate measured by IPCA fell by 3.35 percentage points during 2017 and stood below the target band, the Central Bank decreased the basic interest rate (Sistema Especial de Liquidação e de Custódia), or SELIC rate, to 7.00% by the end of 2017 and to 6.75% in February of 2018, from 13.75% as of the end of 2016.

Brazil closed 2017 with a trade balance surplus of US$67 billion, an improvement in relation to the surplus of US$47.7 billion at the end of 2016. Exports increased 17.6%, registering US$217.8 billion, while imports increased 9.6%, to US$150.7 billion. Foreign Direct Investments inflows into the country have decreased, reaching US$70.3 billion, compared to US$79 billion in 2016. Portfolio investments have registered negative net flows of US$0.8 billion in 2016, in comparison to negative flows of US$20 billion in 2016. As a result of this performance of external accounts, international reserves at the end of 2017 were US$382 billion, an increase of US$10 billion compared to December 31, 2016.

Despite the improvement in economic activity, inflation and external accounts, some areas of the economy remained unfavorable, as is the case of the primary fiscal deficit. The fiscal result this year was another deficit, of 1.7% of the GDP, compared to 2.5% in 2016’s result. The recurring deficit in public finances in the past years led to another loss of investment grade by S&P in 2018. However, risk premium indexes have lowered. The J.P. Morgan Emerging Markets Bond Index Plus (EMBI + Brazil), which tracks total returns for traded external debt instruments in emerging markets, reached 240 basis points by the end of 2017, down from 328 basis points at the end of 2016 and 532 basis points at the end of 2015. Factors such as the favorable external scenario and improvement of some of the macroeconomic fundamentals contributed to diminish the EMBI.

The Real depreciated against the U.S. dollar in 2017 by 1.5%. The exchange rate on December 29, 2017 was R$3.3080 per US$1.00, from R$3.2591 per US$1.00 on December 31, 2016.

Our business is directly affected by the external environment and the Brazilian economy. Lower volatility of the Brazilian Real against the U.S. dollar contributes to the maintenance of the purchasing power of Brazilian consumers and, preventing a negative impact on the ability of our customers to pay for our telecommunications services.

Impact of Inflation on Our Results of Operations

Before 2006, the fees we charged our customers were periodically adjusted by ANATEL based on the inflation rates measured by the IGP-DI.

Starting in 2006, telephone fees were indexed to the IST, which is a basket of Brazilian indexes that reflect the telecommunications sector’s operating costs. Such indexing reduced inconsistencies between revenue and costs in our industry and therefore reduced the adverse effects of inflation on our business. The IST for the twelve-month period ending December 2017 was 3.2% according to the most recent data published by ANATEL.

The table below shows the Brazilian general price inflation (according to the IGP-DI, IPCA and the IST) for the years ended December 31, 2013 through 2017:

	Inflation Rate (%) as Measured by IGP-DI(1)	Inflation Rate (%) as Measured by IPCA(2)	Inflation Rate (%) as Measured by IST(3)

Discussion of Critical Accounting Estimates and Policies

The preparation of the financial statements included in this annual report in accordance with IFRS involves certain assumptions and estimates that affect the amounts presented for revenue, expenses, assets and liabilities and disclosures of contingent liabilities in the notes to the financial statements. Therefore, the uncertainty relating to these assumptions and estimates could lead to results that require a significant adjustment to the accounting value of assets or liabilities affected in future periods. Although we review these estimates and assumptions in the ordinary course of business, the presentation of our financial condition and results of operations often requires our management to make judgments regarding the effects on our financial condition and results of operations of matters that are inherently uncertain. Actual results may differ from those estimated under different variables, assumptions or conditions. For a summary of significant accounting policies and methods used in the preparation of those financial statements, see Note 3 to our Consolidated Financial Statements. The areas involving a higher degree of judgment or complexity are described below.

61

Accounting for long-lived assets

Property, plant and equipment and intangible assets, other than goodwill, are recorded at acquisition cost. Property, plant and equipment and intangible assets with definite useful lives are depreciated or amortized on a straight-line basis over their estimated useful lives. Intangible assets with indefinite useful lives, including goodwill, are not amortized, but are instead, subject to an impairment test on a yearly basis and whenever there is an indication that such assets may be impaired.

Accounting for long-lived assets and intangible assets involves the use of estimates for determining the fair value at their acquisition dates, particularly for assets acquired in business combinations and for determining the useful lives over which they are to be depreciated or amortized as well as their residual value. Useful lives are assessed annually and changed when necessary to reflect current evaluation on the remaining lives in light of technological change, network investment plans, prospective utilization and physical condition of the assets concerned.

The carrying values and useful lives applied to the principal categories of property, plant and equipment, and intangibles, are disclosed in Notes 12 and 13 to our consolidated financial statements.

Impairment of nonfinancial assets, including goodwill

An impairment loss exists when the accounting value of an asset or cash-generating unit exceeds its recoverable amount, which is the higher between the fair value less selling costs and the value in use. The estimated fair value less selling costs is based on the information available from transactions involving the sale of similar assets or the market price less additional costs regarding the disposition of such asset. The value in use is based on the model of discounted cash flow. Cash flows are derived from the budget and do not include activities of reorganization for which the company has not yet been committed or significant future investments that will improve the group of assets of the cash-generating unit subject to the test. The recoverable amount is sensitive to the discount rate used in the method of discounted cash flows as well as to the projected future cash flow and the expected future growth rate used for the purposes of determining terminal value. Furthermore, additional factors, such as technological obsolescence, the suspension of certain services and other circumstantial changes are taken into account.

The carrying value of goodwill and the key assumptions used in performing the annual impairment assessment are disclosed in Notes 3(i) and 13 to our consolidated financial statements.

Provisions for tax, labor, civil and regulatory proceedings

We record provisions for tax, labor, civil and regulatory claims where an outflow of resources is considered probable and a reasonable estimate can be made of the likely outcome. The assessment of the likelihood of loss includes assessing the available evidence, the hierarchy of laws, the available jurisprudence, the most recent court decisions and its materiality in the legal system as well as the evaluation of the case by external counsels. Provisions are reviewed and adjusted to take into account changes in circumstances such as the applicable prescriptive period, results from tax inspections or additional exposure identified based on newly issued court decisions. A significant change in these circumstances or assumptions could result in a corresponding increase or decrease the amount of our provisions.

Additional information on provisions for tax, labor, civil and regulatory proceedings is disclosed in Notes 3(p) and 18 to our consolidated financial statements.

Pension and other post-retirement benefit plan 

The cost of defined benefit retirement plans and other post-employment medical care benefits and the present value of pension and other postretirement obligations are determined using actuarial valuation methods. The actuarial valuation methods involve the use of assumptions about discount rates, expected future salary increases, mortality rates, health care costs trend rates and future increases in retirement benefits and pensions. The obligation of a defined benefit is highly sensitive to changes in these assumptions. All assumptions are reviewed at each year-end. The mortality rate is based on mortality tables available in the country. Future increases in wages and retirement benefits and pensions are based on expected future inflation for Brazil. The assumptions reflect historical experience and our judgment regarding future expectations.

62

The value of our net pension obligation on December 31, 2017, the key financial assumption used to measure the obligation as well as the sensitivity of our pension liability on December 31, 2017 and of the income statement charge in 2015, 2016 and 2017 to changes in these assumptions, is disclosed in Note 30 to our consolidated financial statements.

Fair value of financial instruments

When the fair value of financial assets and liabilities presented on the balance sheet cannot be obtained in active markets, it is determined using valuation techniques, including the method of discounted cash flow. The data obtained for the use of these methods are based as much on the information prevailing in the market as possible. However, when it is not feasible to obtain such information in the market, a certain assumption level is required to establish the fair value. The assumption includes consideration of the data that was used, such as the liquidity risk, credit risk and volatility. Changes in the assumptions regarding these factors could affect the presented fair value of financial instruments.

Additional information on fair value of financial instruments is disclosed in Notes 3(k) and (l) and 31 to our consolidated financial statements.

Taxes

There may be uncertainties regarding the interpretation of complex tax regulations and the amount and timing of future taxable income. We record provisions based on reasonable estimates for potential disagreement with tax authorities from the jurisdictions in which we operate. The value of these provisions is based on several factors such as experience from previous tax audits and different interpretations of tax regulations by the taxable entity and the competent tax authority in charge. Such differences of interpretation may arise in a wide variety of subjects, depending on the prevailing conditions in the domicile of the company. As a result, we may be required to pay more than our provisions or may not be able to recover the full amount of the related tax assets recognized.

We evaluate the recoverability of deferred tax assets based on estimates of future results. This recoverability ultimately depends on our ability to generate taxable profits over the period in which the temporary difference is deductible. The analysis considers the reversal period of deferred tax liabilities, as well as estimates of profits from operations, based on updated internal projections reflecting the latest trends.

Determining the proper valuation of the tax items depends on several factors, including an estimate of the period and the realization of the deferred tax asset and the expected date of payments of these taxes. The actual flow of receipt and payment of income tax could differ from estimates made by us, as a result of changes in tax laws or of unexpected future transactions that may impact tax balances.

Additional information on taxes is disclosed in Notes 3(q), 7 and 16 to our consolidated financial statements.

Revenue recognition

Customer Loyalty Program

We have a customer loyalty program that allows customers to accumulate points when generating traffic from the use of our mobile services. The accrued points may be exchanged for handsets or services, provided the customer has a minimum stipulated balance of points. The consideration received is allocated to the cost of handsets or services and the related points earned based on the relative fair value. The fair value of the points is calculated by dividing the discount value granted as a result of the customer loyalty program by the amount of points needed to carry out the redemption. The fair value accrued on the balances of generated points is deferred and recognized as income upon redemption of points.

63

For determining the quantity of points to be recognized, we apply statistical techniques, which take into consideration assumptions such as estimated redemption rates, expiration dates, cancellation of points and other factors. These estimates are subject to variations and uncertainties due to changes in the redemption behavior of the customers.

A change in the assumptions regarding these factors could affect the estimated fair value of the points under the customer loyalty program and it could affect the apportionment of revenue among the elements and, as a result, revenues in future years.

Multiple-element arrangements

Bundled offers that combine different elements are assessed to determine whether it is necessary to separate the different identifiable components and apply the corresponding revenue recognition policy to each element. Total package revenue is allocated among the identified elements based on their respective fair values.

Determining fair values for each identified element requires estimates that are complex due to the nature of the business.

Changes in estimates of fair values could affect the apportionment of revenue among the elements and, as a result, revenues in future years.

Additional information on revenue recognition is disclosed in Note 3(u) to our consolidated financial statements.

Results of Operations for the Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016

Gross Operating Revenue

Our gross operating revenue increased by 1.9% to R$66,243.2 million in 2017 from R$65,006.7 million in 2016. The table and descriptions below set forth explanations for these variations:

	Year ended December 31,		Percent change
	2017	2016	2017-2016
	(in millions of reais)
Gross operating revenue (a)	66,243.2	65,006.7	1.9%
Deductions from gross operating revenue	(23,036.4)	(22,498.3)	2.4%
Net operating revenues	43,206.8	42,508.4	1.6%

(a) Includes revenues from: telephone services; data transmission and value added services; interconnection fees charged; pay TV and other services.

Net Operating Revenue

Net Operating Revenue increased by 1.6% to R$43,206.8 million in 2017 from R$42,508.4 million in 2016, due to the increase of revenues from telecommunication services, as a result of strong increase in data transmission and value added services revenues from the successful upselling of mobile data bundles, strong migration to 4G and higher smartphone penetration within our customer base, and robust fixed broadband evolution, mainly due to strong growth in ultra-broadband revenues driven by higher adoption of FTTH and footprint expansion. These factors were partially offset by decreasing outgoing voice and interconnection revenues, resulting from decreases in mobile and fixed termination rates mandated by ANATEL, which became effective in February 2017, as described in “Item 4. Information On The Company—B. Business Overview—Regulation of the Brazilian Telecommunications Industry—Mobile Services—Interconnection Fees—Mobile service.”

66

Cost of Sales

Cost of sales decreased by R$550.4 million, or 2.6%, to R$20,272.6 million in 2017 from R$20,823.0 million in 2016. The table and descriptions below set forth explanations for these variations:

	Year ended December 31,		Percent change
	2017	2016	2017-2016
	(in millions of reais)
Cost of goods sold	(1,955.9)	(2,118.9)	(7.7%)

Cost of sales	(20,272.6)	(20,823.0)	(2.6%)

Cost of Goods Sold: Cost of goods sold decreased by R$163.0 million, or 7.7%, to R$1,955.9 million in 2017 from R$2,118.9 million in 2016, primarily as a result of the decline in the overall number of handsets sold due to a value-driven, selective sales strategy adopted in 2017, which focused on selling handsets to higher-value customers.

Depreciation and Amortization: Costs related to depreciation and amortization increased by R$141.5 million, or 2.4%, to R$5,963.1 million in 2017 from R$5,821.6 million in 2016, as a result of the increase in fixed assets, reflecting the higher level of investments made by the Company in the expansion of 4G network and FTTH deployment.

Outside Services and Other: Costs related to outside services and other decreased by R$144.8 million, or 2.5%, to R$5,650.1 million in 2017 from R$5,794.9 million in 2016, as a result of lower costs for acquisition of mobile and TV content.

Interconnection and Network Use: Costs related to interconnection and network use decreased by R$483.1 million, or 25.1%, to R$1,441.0 million in 2017, from R$1,924.1 million in 2016, primarily as a result of the decreases in mobile and fixed termination rates mandated by ANATEL, which became effective in February 2017.

Rental, Insurance, Condominium and Connection Means: Costs related to rent, insurance, condominium and connection means increased by R$298.3 million, or 12.8%, to R$2.624.4 million in 2017, from R$2,326.1 million in 2016, as a result of higher rental and leasing expenses in connection with sites where we install our antennas, due to the expansion in 4G coverage and focus on service quality.

Personnel: Personnel expenses decreased by R$130.8 million, or 13.4%, to R$845.4 million in 2017 from R$976.2 million in 2016, driven by cost savings from corporate restructuring activities executed in the past years and cost-control measures implemented throughout the year.

Taxes, Charges and Contributions: Taxes, charges and contributions decreased by R$68.5 million, or 3.7%, to R$1,792.7 million in 2017, from R$1,861.2 million in 2016, due to lower regulatory taxes paid in the period.

Operating Expenses

Operating Expenses increased by R$984.6 million, or 6.4%, to R$16,302.0 million in 2017, from R$15,317.4 million in 2016. The table and descriptions below set forth explanations for these variations:

67

	Year ended December 31,		Percent change
	2017	2016	2017-2016
	(in millions of reais)
Selling expenses	(13,136.4)	(12,455.4)	5.5%
General and administrative expenses	(2,443.1)	(2,793.3)	(12.5%)
Other operating income (expenses), net	(722.5)	(68.7)	951.7%
Total	(16,302.0)	(15,317.4)	6.4%

Selling Expenses: Our selling expenses increased by R$681.0 million, or 5.5%, to R$13,136.4 million in 2017 from R$12,455.4 million in 2016, mainly due to higher expenses related to telesales and active call center, which are associated with ARPU growth and higher volumes of net additions in high-end customers (postpaid and ultra-broadband services).

General and Administrative Expenses: Our general and administrative expenses decreased by R$350.2 million, or 12.5%, to R$2,443.1 million in 2017, from R$2,793.3 million in 2016, due to lower personnel expenses in the period. 

Other Operating Income (Expenses), Net: Other operating (expenses), net increased by R$653.8 million, or 951.7%, to R$722.5 million in 2017, from R$68.7 million in 2016. The increase is a result of the positive impact of the sale of 1,655 towers in the amount of R$513.5 million in 2016.

Financial Expenses, Net

For the year ended December 31, 2017, financial expenses, Net reached R$903.0 million, decreasing by R$331.5 million or 26.9% when compared to the period ended December 31, 2016, primarily because of a decrease in interest expense as a result of lower interest rates.

Income and Social Contribution Taxes

We recorded an expense from Income and Social Contribution Taxes in the amount of R$1,121.9 million in 2017, compared to an expense of R$1,049.5 million in 2016, as a result of higher income before income tax and social contribution.

The effective rate of income and social contribution taxes decreased to 19.6% in 2017 compared with 20.4% in 2016, as a result of an increased distribution of interest on shareholders’ equity during 2017, which is deductible for income tax purposes.

Results of Operations for the Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015

Gross Operating Revenue

Our gross operating revenue increased by 6.6% to R$65,006.7 million in 2016 from R$60,997.5 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$3,321.2 million, gross operating revenue would have increased by 1.1% or R$688.0 million in 2016, as a result of an increase in revenues from telecommunications services. The table and descriptions below set forth explanations for these variations:

68

	Year ended December 31,		Percent change
	2016	2015	2016-2015
	(in millions of reais)
Gross operating revenue (a)	65,006.7	60,997.5	6.6%
Deductions from gross operating revenue	(22,498.3)	(20,710.7)	8.6%
Net operating revenues	42,508.4	40,286.8	5.5%

(a)       Includes revenues from: telephone services; data transmission and value added services; interconnection fees charged; pay TV and other services.

Net Operating Revenue

Net operating revenue increased by 5.5% to R$42,508.4 million in 2016 from R$40,286.8 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$1,846.9 million, net operating revenue would have increased by 0.9% or R$374.7 million in 2016, mainly as a result of (1) accelerated increase in Data Transmission and Value Added Services Revenues from the successful upselling of mobile data bundles, strong migration to 4G and higher smartphone penetration within our customer base, and robust fixed broadband evolution, boosted by an increased migration from lower to ultra-broadband speeds; and (2) a strong increase of Pay TV Revenues from the improved proportion of IPTV accesses within our Pay TV customer base and selective strategy for the service, focused on increasing profitability. These factors were partially offset by decreasing Outgoing Voice and Interconnection Revenues, resulting from decreases in mobile and fixed termination rates mandated by ANATEL, which became effective in February 2016, as described in “Item 4. Information On The Company—B. Business Overview—Regulation of the Brazilian Telecommunications Industry—Mobile Services—Interconnection Fees—Mobile service.”

Cost of Sales

Cost of sales increased by R$477.9 million, or 2.3%, to R$20,823.0 million in 2016 from R$20,345.1 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$938.8 million, cost of services and goods would have decreased by 2.2% or R$460.9 million in 2016. The table and descriptions below set forth explanations for these variations:

	Year ended December 31,		Percent change
	2016	2015	2016-2015
	(in millions of reais)
Cost of goods sold	(2,118.9)	(2,597.1)	(18.4%)
Depreciation and amortization	(5,821.6)	(5,269.6)	10.5%
Outside services and other	(5,794.9)	(5,400.9)	7.3%
Interconnection and network use	(1,924.1)	(2,595.9)	(25.9%)
Rental, insurance, condominium and connection means	(2,326.1)	(2,051.1)	13.4%
Personnel	(976.2)	(813.6)	20.0%
Taxes, charges and contributions	(1,861.2)	(1,616.9)	15.1%
Cost of sales	(20,823.0)	(20,345.1)	2.3%

Cost of Goods Sold: Our Cost of Goods Sold decreased by R$478.2 million, or 18.4%, to R$2,118.9 million in 2016 from R$2,597.1 million in 2015, primarily as a result of the decline in the overall number of handsets sold due to a new, value-driven, selective sales strategy adopted in 2016, which focused on selling handsets to higher-value customers.

Depreciation and Amortization: Costs related to depreciation and amortization increased by R$552.0 million, or 10.5%, to R$5,821.6 million in 2016 from R$5,269.6 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$383.6 million, costs related to depreciation and amortization would have increased by 3.0% or R$168.4 million in 2016, as a result of the increase in fixed assets, reflecting the higher level of investments made by the Company, partially offset by the savings from extended useful lives of certain of our PP&E resulting from our annual review of the useful life estimate of fixed assets, which amounted to R$157 million.

Outside Services and Other: Costs related to outside services and other increased by R$394.0 million, or 7.3%, to R$5,794.9 million in 2016 from R$5,400.9 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$252.6 million, costs related to outside services and other would have increased by 2.4% or R$137.8 million in 2016, as a result of higher expenses with network maintenance and expansion, partially offset by lower expenses with electricity and insourcing of field services employees.

Interconnection and Network Use: Costs related to interconnection and network use decreased by R$671.8 million, or 25.9%, to R$1,924.1 million in 2016, from R$2,595.9 million in 2015, primarily as a result of the decreases in mobile and fixed termination rates mandated by ANATEL, which became effective in February 2016. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$51.1 million, interconnection fees would have decreased by 27.3% or R$722.9 million in 2016, principally as a result of the decrease in regulatory rates.

Rental, Insurance, Condominium and Connection Means: Costs related to rental, insurance, condominium and connection means increased by R$275.0 million, or 13.4%, to R$2,326.1 million in 2016, from R$2,051.1 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$104.4 million, costs related to rent, insurance, condominium fees and leased lines would have increased by 7.9% or R$170.6 million in 2016, as a result of higher rental and leasing expenses in connection with sites where we install our antennas, due to the expansion in 4G coverage and focus on service quality.

Personnel: Personnel expenses increased by R$162.6 million, or 20.0%, to R$976.2 million in 2016 from R$813.6 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$110.4 million, personnel expenses would have increased by 5.6% or R$52.2 million in 2016, as a result of (1) the insourcing of field services and call center employees, aimed at improving the experience of higher-value customers and increasing productivity; and (2) the increase in salaries from collective bargaining agreements of 7.0% granted on September 2015 and 2016. These factors were partially offset by cost savings from corporate restructuring activities and cost-control measures implemented throughout the year.

Taxes, Charges and Contributions: Taxes, charges and contributions increased by R$244.3 million, or 15.1%, to R$1,861.2 million in 2016, from R$1,616.9 million in 2015, primarily due to higher regulatory taxes. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$33.1 million, taxes, fees and contributions would have increased by 12.8% or R$211.2 million in 2016.

Operating Expenses

Operating Expenses increased by R$615.3 million, or 4.2%, to R$15,317.4 million in 2016, from R$14,702.1 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$564.7 million, operating expenses would have increased by 0.3% or R$50.6 million in 2016. The table and descriptions below set forth explanations for these variations:

70

	Year ended December 31,		Percent change
	2016	2015	2016-2015
	(in millions of reais)
Selling expenses	(12,455.4)	(12,005.5)	3.7%
General and administrative expenses	(2,793.3)	(2,142.4)	30.4%
Other operating income (expense), net	(68.7)	(554.2)	(87.6%)
Total	(15,317.4)	(14,702.1)	4.2%

Selling Expenses: Our selling expenses increased by R$449.9 million, or 3.7%, to R$12,455.4 million in 2016 from R$12,005.5 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$407.7 million, selling expenses would have increased by 0.3% or R$42.2 million in 2016, as a result of (1) lower costs with commissions and sales promoters in retail stores; (2) lower expenses with publicity and marketing, due to the synergies generated with the unification of brands (Vivo and GVT) as of April 2016, eliminating communication redundancies; and (3) lower costs with call center services due to lower volume of calls driven by digitalization, simplification of offers and improved customer experience. These factors were partially offset by an annual increase in provisions for bad debt, driven by higher default levels in the B2B segment.

General and Administrative Expenses: Our general and administrative expenses increased by R$650.9 million, or 30.4%, to R$2,793.3 million in 2016, from R$2,142.4 million in 2015, primarily because results for the first four months of 2015 do not include GVT, as the latter was consolidated into our financial statements as from May 1, 2015. If we considered as part of our results the effects of GVT’s pro forma consolidation since January 1, 2015, which totaled R$154.1 million, general and administrative expenses would have increased by 21.6% or R$496.8 million in 2016, as a result of (1) higher expenses with IT development and integration, as part of the GVT consolidation process; and (2) higher expenses with commercial efficiency and real estate optimization.

Other Operating Income (Expenses), Net: Other net operating income (expenses), net decreased by R$485.5 million, or 87.6%, to R$68.7 million in 2016, from R$554.2 million in 2015. This decrease is a result of the gain on sale of 1,655 towers on March 31, 2016, totaling R$513.5 million.

Financial Expenses, Net

For the year ended December 31, 2016, financial expenses, net reached R$1,234.5 million, increasing by R$386.3 million or 45.5% when compared to the period ended December 31, 2015, mainly due to the monetary indexation of contingencies, partially compensated by financial losses in 2015 related to the foreign exchange variation on GVT’s loans and financing denominated in foreign currency, whose result was negatively impacted by the appreciation of the Euro against the Real.

Income and Social Contribution Taxes

We recorded an expense from income and social contribution taxes in the amount of R$1,049.5 million in 2016, compared to an expense of R$973.2 million in 2015. This variation was a result of higher income before income tax and social contribution.

The effective rate of income and social contribution taxes decreased to 20.4% in 2016 compared with 22.2% in 2015, primarily as a result of an increased distribution of interest on shareholders’ equity during 2016, which is deductible for income tax purposes.

B. Liquidity and Capital Resources

General

We fund our operations and capital expenditures primarily from operating cash flows, loans obtained from financial institutions or development banks, and debentures. As of December 31, 2017, we had R$4.1 billion in cash and cash equivalents. We do not have any material unused sources of liquidity.

Our principal cash requirements include:

·the servicing of our indebtedness;

·capital expenditures; and

·the payment of dividends.

Our management believes that our sources of liquidity and capital resources, including working capital, are adequate for our present requirements.

Sources of Funds

Our cash flow from operations was R$12.6 billion in 2017, an increase of 10.5% compared to R$11.4 billion in 2016. The increase in cash flow from operations is a reflection of an increase in revenues from mobiles telecommunications services, mainly driven by data and digital services revenues, which represented 72.1% of our mobile service revenues, and the increase of broadband revenues, mainly in ultra-broadband, due to our strategy to expand our FTTH footprint in existing and new cities, partially offset by an increase in operating expenses, mainly due to the cost of sales and IT development.

Our cash flow from operations was R$11.4 billion in 2016, an increase of 15.6% compared to R$9.9 billion in 2015. The increase in cash flow from operations is a reflection of a significant increase in revenues from telecommunications services and revenues from Pay TV, partially offset by (1) an increase in costs of services and goods, due to higher personnel and taxes costs and (2) an increase in operating expenses, impacted by higher selling and general and administrative expenses. A portion of the increases mentioned above were related to the consolidation of GVT results for the full year in 2016 as compared to eight months in 2015.

Uses of Funds

Our cash flow used in investing activities was R$8.4 billion in 2017 compared to R$6.9 billion in 2016. The increase in cash flow used in investing activities of R$1.5 billion in 2017 compared to 2016 was primarily due to the additions to property, plant and equipment and intangible assets, to the acquisition of Terra in 2017, and to proceeds from the one-time sale of fixed assets in 2016.

Our cash flow used in investing activities was R$6.9 billion in 2016 compared to R$14.6 billion in 2015. The decrease in cash flow used in investing activities of R$7.7 billion in 2016 compared to 2015 was primarily due to the acquisition of GVT in 2015 (R$8.5 billion, net of cash acquired from GVT).

Our cash flow used in financing activities recorded an outflow of R$5.3 billion in 2017 compared to an outflow of R$4.8 billion in 2016. The increase in cash flow used in financing activities of R$0.5 billion in 2017 compared to 2016 was due primarily to the increase in payment of dividends and interest on equity (R$0.7 billion), increase in payments of loans and debentures (R$2.3 billion) partially offset by debentures raised R$3.0 billion in 2017.

Our cash flow used in financing activities recorded an outflow of R$4.8 billion in 2016 compared to an inflow of R$5.4 billion in 2015. The increase in cash flow used in financing activities of R$10.2 billion in 2016 compared to 2015 was due primarily to the R$16.1 billion capital increase performed by the Company in 2015, partially offset by a decrease in payment of loans and debentures in 2016 compared to 2015 (R$6.5 billion), along with decrease in dividends and interest on equity paid in 2016 compared to 2015 (R$712.3 million).

Total debt				8,461.8
Current				3,033.4
Noncurrent				5,428.4
(1) The Currency Basket Charge (Encargos da Cesta de Moedas), or ECM, is a rate disclosed by BNDES on a quarterly basis.
(2)   Our finance leases are related to towers and rooftops, IT equipment leases, infrastructure rent and other means of transmission.

Interest and principal payments on our indebtedness as of December 31, 2017 due in 2018 and 2019 total R$3,033.4 million and R$845.5 million, respectively.

The agreements that govern the majority of our outstanding loans and financings contain certain standard restrictive covenants, including financial covenants. These agreements may provide for the acceleration of the full balance of our obligations in the event of any default. In general, these agreements are subject to acceleration of maturity upon: (i) the inclusion in our shareholders’ agreement, bylaws or articles of incorporation or those of the companies that control us of conditions leading to restrictions or loss of ability to pay financial obligations arising from these agreements; (ii) a conviction or final judgment against us in connection with child labor, slave labor or a crime against the environment; or (iii) liquidation, dissolution, insolvency; voluntary bankruptcy, judicial or extrajudicial recovery to any creditor or class of creditors.

As of December 31, 2017, we were not in default of any of our obligations and therefore none of our liabilities were subject to acceleration.

Foreign Exchange and Interest Rate Exposure

We face foreign exchange risk due to our foreign currency-denominated indebtedness, accounts payable (including our capital expenditures, particularly equipment) and receivables in foreign currency. A real devaluation may increase our cost of debt and certain commitments in a foreign currency. Our revenue is earned in reais, and we have no material foreign currency-denominated assets, except income from hedging transactions, interconnection of international long-distance services and services rendered to customers outside Brazil. Equity investments in foreign companies also suffer effects with variations in the exchange rate.

73

On December 31, 2017, 2.7% of our R$8.5 billion of financial indebtedness was denominated in U.S. dollars and UMBNDES. See Note 33 to the Consolidated Financial Statements. Devaluation of the real causes exchange losses on foreign currency-denominated indebtedness and commitments and exchange gain on foreign currency-denominated assets and corporate stakes in foreign companies. 

We use derivative instruments to limit our exposure to exchange rate risk. Since September 1999, we have hedged all of our foreign currency-denominated bank debt using swaps and other derivative instruments. Since May 2010, the company began using net balance coverage, which is the hedging of net positions in foreign exchange exposures, or assets (issued invoices) minus liabilities (received invoices) for foreign exchange exposures, substantially reducing our risk to fluctuations in exchange rates. We could still continue to face exchange rate exposure with respect to our planned capital expenditures however, as a small partof our planned capital expenditures are denominated or indexed in foreign currencies (mostly U.S. dollars). We systematically monitor the amounts and time of exposure to exchange rate fluctuations and may hedge positions when deemed appropriate.

The largest part of our reais denominated debt originally pays interest as a percentage of the CDI or has been swapped to do so. The CDI – Certificate of Interbank Deposits (Certificado de Depósito Interbancário) is an index based upon the average rate of operations transacted among the banks within Brazil. With the CDI being a floating rate, we remain exposed to market risk. This exposure to the CDI is also present in long derivatives positions and financial investments, which are indexed to percentages of the CDI.

Capital Expenditures and Payment of Dividends

Our principal capital requirements are for capital expenditures and payments of dividends to shareholders. Capital expenditures consisted of additions to property, plant and equipment and additions to intangible assets, including licenses which totaled R$8.0 billion, R$8.2 billion and R$7.7 billion for the years ended December 31, 2017, 2016 and 2015, respectively. These expenditures relate primarily to the expansion of our network. We may seek financing for part of our capital expenditures and cash management assistance from the Brazilian government, in particular from BNDES, which is the main government financing agent in Brazil, as well as from the local or foreign capital markets or from local and foreign financial institutions. See “Item 4. Information on the Company—A. History and Development of the Company—Capital Expenditures.”

Pursuant to our bylaws and Brazilian Corporate Law, we are required to distribute a mandatory minimum dividend of 25% of “adjusted net income” (as defined below) in respect of each fiscal year to the extent earnings are available for distribution. Holders of preferred shares are assured priority in the reimbursement of capital, without a premium, and are entitled to receive cash dividends that are 10% higher than those attributable to common shares.

Adjusted net income, as determined by Brazilian Corporate Law, is an amount equal to our net income adjusted to reflect allocations to or from (i) legal reserve, (ii) statutory reserve and (iii) a contingency reserve for anticipated losses, if any.

We may also make additional distributions to the extent that we have profits and reserves available to distribute. All of the above distributions may be made as dividends or as tax-deductible interest on shareholders’ equity. Interest on shareholders’ equity are tax-deductible payments pursuant to Brazilian Corporate law, that a company may make, in addition to dividends, which the company may treat as financial expenses for tax and social contribution purposes.  For more information on the payment of interests on shareholders’ equity, see “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividends and Dividend Distribution Policy—Dividends and Interest on Shareholders’ Equity.” We distributed dividends and interest on shareholders’ equity of R$4.6 billion, R$4.1 billion and R$3.3 billion in 2017, 2016 and 2015, respectively.

74

Our Management expects to meet 2018 capital requirements primarily from cash provided from our operations. Net cash provided by operations was R$12.6 billion, R$11.4 billion and R$9.9 billion in 2017, 2016 and 2015, respectively.

Adjustments to net income for purposes of calculating the basis for dividends include allocations to various reserves that effectively reduce the amount available for the payment of dividends. For the fiscal year ended December 31, 2017, in addition to the interim dividend and interest on own capital payments made in 2017, management decided to propose (i) the allocation of R$297.0 million of profits available for distribution to Reserve of Modernization and Expansion and (ii) an additional proposed dividend to shareholders in the amount of R$2.2 billion. The proposal to allocate profits to Reserve of Modernization and Expansion and to pay dividends will be approved at the shareholders’ meeting that will approve the 2017 annual report. See “Item 3. Key Information—D. Risk Factors—Risks Relating to the Preferred Shares and the ADSs—Holders of our Preferred Shares and ADSs generally do not have voting rights” and “Item 10. Additional Information—B. Memorandum and Articles of Association—Description of Our Bylaws—Voting Rights.”

Accounting Pronouncements

The accounting policies adopted in the preparation of the consolidated financial statements for the year ended December 31, 2017 are consistent with those used in the preparation of the consolidated annual financial statements for the year ended December 31, 2016. The following amendments to standards published by the International Accounting Standards Board (IASB) come into force for annual periods beginning on or after January 1, 2017:

·Improvements to IFRS 2014-2016: The annual improvements projects provide a vehicle for making non-urgent but necessary amendments to IFRSs, with the aim of removing inconsistencies and clarifying wording. The amendments related to IFRS 12 Disclosure of Interests in other Entities, aimed clarifying the scope of the standard, come into force for annual periods beginning on or after January 1, 2017, whereas the rest of the improvements come into force for annual periods beginning on or after January 1, 2018. The amendments related to IFRS 12 do not have an impact on the Company’s consolidated financial statements since, as of December 31, 2017, the Company does not have participations that are classified as held for sale, as held for distribution or as discontinued operations.

·Amendments to IAS 7, Disclosure Initiative: The amendments to IAS 7 require entities to provide disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flows, such as the issue and repayments of loans, and non-cash changes, such as unpaid acquisitions, sales and exchange differences.

·Amendments to IAS12, Recognition of Deferred Tax Assets for Unrealised Losses: The amendments clarify the requirements on recognition of deferred taxes when the tax base of an asset exceeds its fair value.

The Company considered these amendments in the preparation of the annual consolidated financial statements; however, did not generate a significant impact on its results or financial position.

On the date of preparation of these financial statements, the following IFRS amendments had been published; however, their application was not mandatory. The Company does not adopt early any pronouncement, interpretation or amendment that has been issued, before application is mandatory.

75

 

Based on the analyses made to date, the Company estimates that the adoption of many of these standards, amendments and interpretations will not have a significant impact on the consolidated financial statements in the initial period of adoption. However, the following issued but not yet effective standards are expected to have a significant impact on the consolidated financial statements at the time of their adoption and prospectively.

IFRS 15 Revenues from Contracts with Customers

IFRS 15 sets out the requirements for recognising revenue from contracts with customers. The new requirements are expected to affect the following aspects, among others:

· Under IFRS 15, for bundled packages that combine multiple wireline, wireless, data, internet or television goods or services, the total revenue will be allocated to each performance obligation based on their standalone selling prices in relation to the total consideration of the package and will be recognized when (or as) the obligation is satisfied, regardless of whether there are undelivered items. This differs from current accounting where the portion of the total consideration that is contingent upon delivery of undelivered elements is not allocated to the delivered elements. Consequently, when bundles include a discount on equipment, the adoption of these new requirements will result in an increase in revenues recognized from the sale of handsets and other equipment, generally recognized upon delivery to the end customer, in detriment of ongoing service revenue over subsequent periods. To the extent that the packages are marketed at a discount, the difference between the revenue from the sale of equipment and the consideration received from the customer upfront will be recognized as a contract asseton the statement of financial position.

· Under the current accounting policy, all expenses directly related with obtaining a contract (sales commissions and other third party acquisition costs) are expensed when incurred. However, IFRS 15 requires the recognition of an asset for those costs that are incremental to obtain a contract and that are expected to be recovered and its subsequent amortisation over the same period as the revenue associated with such asset. Similarly, certain contract fulfilment costs, which are currently expensed when incurred, will be deferred under IFRS 15 to the extent that they relate to performance obligations that are satisfied over time.

76

·The guidance in IFRS 15 for the distinction between agent and principal is based on the concept of “control” that may differ from the currently applied notion of transfer of “risks and rewards”. As a result, with the adoption of IFRS 15, the Company will record revenue from the sale of handsets to dealers at the time of delivery and not at the time of sale to the final customer.

·Compared to the current revenue standard, IFRS 15 sets out more detailed requirements on how to account for contract modifications. Certain changes must be accounted for as a retrospective change (i.e. as a continuation of the original contract), while other modifications must be accounted for prospectively as separate contracts, like the end of the original contract and the creation of a new one.

In addition to this, IFRS 15 allows for two transition methods, namely the full retrospective method and the modified retrospective method with the cumulative effect from initial application recognized as an adjustment to the opening balance of retained earnings at the date of initial application. The Company will adopt the latter and prior-year comparatives will not be restated; instead, the Company will disclose the nature and amount of the changes in items in the statement of financial position and the income statement as a result of applying IFRS 15 for the first time.

It is also possible to elect to apply certain practical expedients to facilitate the application of the new criteria. The Company has evaluated which of them will be adopted in the implementation of the standard with the objective of reducing the complexity in its application. The main practical expedients that the Company will adopt are:

·Completed contracts: the Company will not apply the standard retrospectively to those contracts that are completed at January 1, 2018.

·Portfolio approach: the Company will apply the requirements of the standard to groups of contracts with similar characteristics, since, for the clusters identified, the effects do not differ significantly from an application on a contract by contract basis.

·Financial component: it will not be considered significant when the period between the moment when the promised good or service is transferred to a customer and the moment when the customer pays for that good or service is one year or less.

·Costs to obtain a contract: these costs will be recognized as an expense when incurred if the amortisation period of the asset that the entity would otherwise recognize is one year or less.

The process of implementing the new requirements involves the introduction of modifications to the current information systems, the implementation of new IT tools, and changes in the processes and controls of the entire revenue cycle in the Company. This process of implementation in the Company entails a high degree of complexity due to factors such as a large number of contracts, numerous data source systems, as well as the need to make complex estimates.

From the analysis performed on the transactions of the last financial year considering commercial offers as well as the volume of contracts affected, the Company estimates that the adoption of the new revenue recognition requirements on its equity is expected to result in an increase in retained earnings of 156 million reais before deferred taxes, being the most significant impact due to the changes introduced by IFRS 15 relating to the first-time recognition of contract assets that, under IFRS 15, lead to the earlier recognition of revenue from the sale of goods, and the activation and deferral of the incremental costs related to the obtaining contracts and contract fulfilment costs that, under IFRS 15, result in the later recognition of customer acquisition costs and other selling expenses.

As the accounting effects of the transition to the new standard will be recognized directly in equity, the effects on profit or loss in 2018 will be related to changes in the point in time at which revenue and expenses are realized. The Company expects a shift from revenues from the provision of services to revenues from the sale of goods, by between 0.3 and 0.7 percentage points on the assumption that there are no significant changes to business models or products offered.

77

IFRS 9 Financial Instruments

IFRS 9 is applicable to financial assets and financial liabilities. As a result of the analysis of the effects of the new requirements introduced by this standard certain expected impacts have been identified in relation with the following aspects, among others:

·IFRS 9 simplifies the current measurement model for financial assets and establishes three main categories: amortised cost, fair value through profit or loss and fair value through Other Comprehensive Income (OCI), depending on the business model and the characteristics of the contractual cash flows. Regarding recognition and measurement of financial liabilities there are not significant changes from current criteria except for the recognition of changes in own credit risk in OCI for those liabilities designated at fair value through profit or loss.

·IFRS 9 introduces a new model for impairment losses on financial assets, i.e. the expected credit loss model, which replaces the current incurred loss model. The Company will apply the simplified approach and record lifetime expected losses on all trade receivables. Consequently, the application of the new requirements will probably lead to an acceleration in the recognition of impairment losses on its financial assets, mainly trade receivables.

·Under current accounting, a hedge must be highly effective both, prospective and retrospectively, while IFRS 9 introduces a new, less restrictive, accounting model for hedging, requiring an economic relationship between the hedged item and the hedging instrument and that the coverage ratio be the same as that applied by the entity for its risk management. Likewise, the new standard modifies the criteria for documentation of hedging relationships.

·In addition to this, the Company's financial statements will include more detailed disclosures with relevant information regarding financial assets and liabilities.

As a result of the analysis of the new standard, the Company expects that the key changes will relate to documentation of policies and hedging strategies, as well as the estimation and timing of recognition of expected losses on receivables from customers. The Company has decided to apply the option that allows not to restate comparative periods to be presented in the year of initial application.

Based on the analysis performed to date, the Company estimates that the new impairment requirements is expected to result upon initial adoption in a decrease of 354 million reais in retained earnings, before deferred taxes, as a result of the increase in the bad debt provision balance on receivables from customers recognized under IAS 39. 

IFRS 16 Leases

IFRS 16 requires lessees to recognise assets and liabilities arising from all leases (except for short-term leases and leases of low-value assets) in the statement of financial position.

The Company acts as a lessee on a very significant number of lease agreements over different assets, such as third-party towers, circuits, office buildings and stores and land where the towers are located, mainly. A significant portion of these contracts is accounted for as operating lease under the current lease standard, with lease payments being recognized generally on a straight-line basis over the contract term.

The Company is currently in the process of estimating the impact of this new standard on such contracts. This analysis includes the estimation of the lease term, based on the non-cancellable period and the periods covered by options to extend the lease, when the exercise depends only on Telefônica and where such exercise is reasonably certain. This will depend, to a large extent, on the specific facts and circumstances by class of assets in the telecom industry (technology, regulation, competition, business model, among others).  In addition to this, the Company will make assumptions to calculate the discount rate, which will mainly be based on the incremental borrowing rate of interest for the estimated term. On the other hand, the Company is considering not to separately recognise non-lease components from lease components for those classes of assets in which non-lease components are not material with respect to the total value of the lease.

78

In addition to the mentioned estimations, the standard allows for two transition methods: retrospectively for all periods presented, or using a modified retrospective approach where the cumulative effect of adoption is recognized at the date of initial application. The Company has tentatively decided to adopt the latter transition method; therefore the Company would recognise the cumulative effect of initial application as an adjustment to retained earnings in the year of initial application of IFRS 16. Also, certain practical expedients are available on first-time application in connection with the right of use asset measurement, discount rates, impairment, leases that finish within the twelve months subsequent to the date of first application, initial direct costs, and term of the lease. The Company is evaluating which of these practical expedients will be adopted. In this regard, the Company is considering opting for the practical expedient that allows not reassessing whether a contract is or contains a lease on the date of initial application of IFRS 16 but to directly apply the new requirements to all those contracts which under current accounting were identified as a lease.

Due to the different alternatives available, together with the complexity of the estimations and the significant number of lease contracts, the Company has not yet completed the implementation process, so at present it is not possible to make a reasonable estimation of the impact of initial application of the new requirements. However, based on the volume of contracts affected, as well as the magnitude of the future lease commitments, as disclosed in Note 32 herein, the Company expects that the changes introduced by IFRS 16 will have a significant impact on its financial statements from the date of adoption, including the recognition on the balance sheet of right of use assets and their corresponding lease obligations in connection with the majority of contracts that are classified as operating leases under the current lease standard. Also, amortization of the right of use assets and recognition of interest costs on the lease obligation on the statements of income will replace amounts recognized as lease expense under the current lease standard. Classification of lease payments in the statement of cash flows will also be affected by the requirements of the new lease standard. On the other side, the Company's Financial Statements will include broader disclosures with relevant information regarding lease contracts.

Consumption patterns in Brazil have converged and deepened towards data, replacing traditional services. Customers are willing to be enlightened through better mobile connection, faster data speeds and outstanding customer care. Accordingly, we plan to continue efficiently investing in a more modern infrastructure in the mobile segment through the 4G technology and in the fixed segment through an increased ultra-broadband footprint, improving the experience of our customers with faster and reliable connections through FTTH.

In a macroeconomic scenario currently reflecting some level of recovery, but also characterized by volatility in light of the general elections in 2018, we expect a competitive environment that continues to emphasize sustainability, profitability and heightened concern regarding the delivery of higher quality offerings and customer service.

We maintain our top priority of making our customers’ digital lives easier to manage. On a daily basis, we are committed to provide digital and converging cross-platform services, delivering the best customer experience while continuously building a competitive advantage that attracts customers and strengthens loyalty of our current client base.

We believe that revenue growth will continue to be driven over the next few years by mobile and fixed data services.

89

One of the members of our Board of Directors was elected by the preferred shareholders in a separate voting process and the others were elected by the holders of common shares.

Fiscal Board

Brazilian Corporate Law and our bylaws each require that we maintain a statutory Fiscal Board (Conselho Fiscal). Our permanent, statutory Fiscal Board, which is a separate and distinct entity from our outside auditors, is primarily charged with certain advisory, reporting, oversight and review functions with respect to the company’s financial statements. Our statutory Fiscal Board is also responsible for rendering opinions on management’s annual report and management proposals, including financial statements, to be submitted at shareholders meetings relating to a change in the company’s capital composition, investment plans, budget, debenture issuances or subscription bonuses, payment of dividends and consolidations, mergers and spin-offs. However, the statutory Fiscal Board, as required by Brazilian Corporate Law and our bylaws, has only an advisory role and does not participate in the management of the company. Decisions of the statutory Fiscal Board are not binding on the company under Brazilian Corporate Law.

In accordance with Brazilian Corporate Law and our bylaws, the Fiscal Board consists of a minimum of three (3) and a maximum of five (5) active members and an equal number of alternates. The members of the Fiscal Board are elected for a period of one (1) year and may be reelected.

One member of the Fiscal Board and his or her alternate must be elected by holders of preferred shares in a separate voting process. The following are the current members of the Fiscal Board:

(1)Mr. Flavio Stamm and Mr. Gilberto Lerio were elected by the preferred shareholders in a separate voting process, with no participation of the controlling shareholder

D.    Employees

As of December 31, 2017, we had 33,622 employees. We have full-time and part-time employees. Our part-time employees work primarily at our stores and call centers. Our employees are divided into the following categories: 36.2% in production and operations; 37.4% in sales; 19.3% in customer care; and 7.0% in support.

As of December 31, 2016, we had 33,331 employees. We have full-time and part-time employees. Our part-time employees work primarily at our stores and call centers. Our employees are divided into the following categories: 36.8% in production and operations; 35.9% in sales; 19.6% in customer care; and 7.7% in support.

As of December 31, 2015, we had 33,847 employees. We have full-time and part-time employees. Our part-time employees work primarily at our stores and call centers. Our employees are divided into the following categories: 38.0% in production and operations; 34.5% in sales; 19.7% in customer care; and 7.8% in support.

Approximately 10% of our employees are union members. These unions have state representation, so we have employees represented by the unions of all 26 states plus the Federal District. In turn, 19 of these unions are associated with the National Federation of Telecommunications Workers (Fenattel) and other 8 unions are associated with the Interstate Federation of Workers and Researchers in Telecommunications (Fitratelp). Besides these 27 unions, we have employees represented by São Paulo Engineers’ Union.

Our collective bargaining agreement for these employees was renewed for 100% of our employees on September 1, 2017 for the economic clauses, since the social clauses were negotiated in 2016 with validity of two years, that is, all clauses will be in force until August 31, 2018.

Our management considers relations with our work force to be very good. We have never experienced a work stoppage for a significant period or that had a material effect on our operations.

Pension Plans

Before December 1999, the SISTEL plan (managed by the Fundação Sistel de Seguridade Social), was a defined benefit plan that supplemented government-provided retirement benefits, was adopted for all the employees of the former Telebrás System and we were contingently liable for all of the unfunded obligations of the plan.

In January 2000, we and the other companies that formerly belonged to the Telebrás system agreed to divide the existing SISTEL plan into 15 separate plans, resulting in the creation of private plans covering those employees already enrolled in the SISTEL plan. These new private pension plans, called PBS plans, were still administered by the Fundação Sistel and have retained the same terms and conditions of the initial plan. The division was carried out to allocate liability among the companies that formerly belonged to the Telebrás system according to each company’s contributions with respect to its own employees. Joint liability among the SISTEL plan sponsors continues with respect to retired employees, who will necessarily remain members of the PBS plans.

Under the PBS plans, we made monthly contributions to each plan according to a percentage of the salary of each employee who was a participant of such plan. Each employee member also made a monthly contribution to their plan on the basis of age and salary. Pension benefits of members of PBS plans vested at the same time their retirement benefits vested under the government-provided retirement plan. Fundação Sistel operates independently from us, and its assets and liabilities are fully segregated.

Beginning in 2000, we decided to establish defined contributions plans, and offered these to participants in our PBS plans, as well as to employees who do not already have a pension plan. Unlike the PBS plans, which are defined benefits plans, the defined contribution plans are financed by contributions from participating employees, as well as by our contributions as sponsor, which are credited to the individual accounts of the participants. We are responsible for all management and maintenance expenses of these plans, including the risks of death and permanent injury of the participants.

In 2005, we created a closed social security entity called Visão Prev Sociedade de Previdência Complementar to manage the pension plans of the Telefónica group in Brazil.  From 2005 to 2010, management of all plans was transferred from Fundação Sistel to Visão Prev, except for PBS-A Plan, which continues to be managed by Fundação Sistel.

In 2011, the Visão Telesp, Visão Telefônica Empresas, Visão Assist and Visão ATelecom plans were consolidated into the Visão Telefônica plan. Following the acquisition of the Tevecap S.A., or TVA, we became sponsors of Abrilprev Plan, a defined contribution plan for employees of these companies.

On September 1, 2013, we began offering the Visão Multi Pension Plan to our employees who do not have a pension plan. This plan was launched in order to standardize private pension benefits following the corporate restructuring of our subsidiaries in Brazil. In this plan, participants can make basic contributions of 1-2% and additional contributions of 0-5% of salary and we contribute a percentage between 50% to 125%, depending on length of service.

In July 2014, a spin-off of the Abrilprev plan covering employees of the TVA companies was approved and its management transferred to Visão Prev. This plan is now called Visão TVA.

In September 2015, the merger of the plans CelPrev Telemig, Visão Celular CRT, Visão Telebahia Celular, Visão Telergipe Celular, Visão Telerj Celular, Visão Telest Celular, TCP Prev by the plan Visão Telefônica was approved. Also in September 2015 the merger of the plan Visão TVA by the plan Visão Multi was approved.

In May 2015, the company also became a sponsor of private pension plans of the open entity Brasilprev, that were offered to the employees of the GVT Group companies.

Between January and March 2016, the process of migration of the 259 participants of the Brasilprev plan to the Visão Multi plan was carried out.

94

In 2016, we sought to improve efficiency in the management of private pension plans, aligning the main market practices, and standardizing the benefit through actions of: (i) implementing the collection in July of administrative fees from the participants for the maintenance of the Visão Multi plan; (ii) reversion of 100% of the value of the leftover fund to the company (50% were reverted until 2015, the other part being allocated to the participants); (iii) incorporation of plans managed by Visão Prev.

In March 2016, the process of migrating the PBS Telemig plan to the Telefónica BD plan was approved.

In November 2016, the migration of the Visão Terra plan to the Visão Multi plan was approved.

In December 2016, the migration of the Visão TGestiona and Vivo Prev plans to the Visão Telefônica Plan was approved. In March 2017, this migration process to the Visão Telefônica plan was completed, which impacted 5,829 (or 64%) of the participating employees.

Considering the total workforce, 28.2% of our employees are participants of our private retirement plans. 

E.    Share Ownership

None of our directors or executive officers beneficially owns, on an individual basis, 1% or more of our common or preferred shares (including ADSs representing preferred shares) or of our total equity share capital. We currently have three share ownership plans in place:

1)Performance & Investment Plan (“PIP”)

·The general shareholders’ meeting of Telefónica S.A. (our indirect controlling shareholder), held on May 18, 2011, approved a new long-term incentive plan - Performance & Investment Plan, or the PIP, for executives of Telefónica S.A. and of other entities within the Telefónica group, including us. The plan grants a certain number of shares of Telefónica S.A. to selected participants who meet the necessary requirements of the program.

·The new PIP program was divided in three cycles (2011, 2012 and 2013), each of which has a three-year duration, with the start date of each cycle occurring in July 1 of each year.  The cycles are independent of each other.

·The executives of Telefónica group are eligible to participate in the program and they must remain in the Telefónica group for a minimum period of three years starting from the date they were qualified. In order to deliver the shares to executives at the end of each three-year cycle, the Telefónica group performs an analysis to determine if the evaluation indicators of the shares of Telefónica, which are primarily measured in terms of the total return to shareholders, or TRS, have been achieved.

·The distribution of shares related to the first cycle (2011-2014) did not occur, given that the minimum TRS set forth in the program was not achieved.

·The 2012-2015 cycle ended in June 2015 and, after reaching the TSR, 68 executives of the Company were entitled to receive 258,552 shares of Telefónica S.A..

·The 2013-2016 cycle ended in June 2016 and the distribution of shares did not occur, given that the minimum TRS set forth in the program was not achieved.

·In 2014, Telefônica approved the extension of this program for three cycles, each lasting three years, beginning on October 1, 2014 and ended on September 30, 2017. The number of shares is communicated early in the cycle, and after the period of three years from the grant date, the shares are transferred to the participant if the specified TRS is reached.

·The next distributions of shares are scheduled as follows:

·Cycle 2014-2017: occurred in September 2017, and the distribution of shares did not occur, given that the minimum TRS set forth in the program was not achieved.

95

·Cycle 2015-2018: scheduled to occur in September 2018, with 82 executives (including three executives appointed pursuant to the bylaws) of Telefônica Brasil having the potential right to receive 467,966 shares of Telefónica S.A. (including initial shares and co-investing), which, as of December 31, 2017, accrued R$8.2 million.

2)Global Employee Share Plan (“GESP”)

The program is only available to certain director-level executives, not including members of the Board of Directors and Fiscal Board.

Telefónica’s Annual Shareholders' Meeting, held on May 30, 2014, approved an incentive plan for the acquisition of Telefónica’s shares by the Telefónica Group employees at an international level, including employees of the Company and its subsidiaries. This program is not available to members of the Board of Directors or Fiscal Board.

Through this plan, the possibility of acquiring shares of Telefónica is offered, with a certain number of shares being delivered to participants whenever certain requirements are met.

The total planned duration of the plan was 2 years. The employees enrolled in the plan were able to acquire shares of Telefónica through monthly contributions of 25 to 150 euros (or equivalent in local currency), with a maximum value of 1,800 euros over a period of 12 months (period of purchase).

The delivery of shares will occur after the vesting of rights pursuant to the plan, as from July 31, 2017, and is conditioned on: (i) continued employment with the company during the two-year duration of the program (the rights vesting period), subject to certain special conditions relating to casualties; and (ii) the exact number of shares to be delivered at the end of the vesting period depends on the number of shares acquired and held by employees. Thus, the employees enrolled in the plan who remained in the Telefónica Group and held the shares acquired for an additional period of twelve months after the end of the purchase period are entitled to receive a free share for each share they have acquired and held until the end of the vesting period.

3)Talent for the Future Share Plan (“TFSP”)

·The Annual General Shareholders' Meeting of Telefónica held in 2014 approved a long-term program  to reward the commitment, outstanding performance and high potential of its executives globally with the allocation of shares of Telefónica.

·Participants do not need to pay for their initial shares. The initially expected total duration of the plan is three years. The beginning of the cycle was on October 1, 2014 and finished on September 30, 2017. The number of shares is stated in the beginning of the cycle and, after the period of three years from the grant date, the shares will be transferred to the participant if the goal is reached.

·The delivery of shares is conditional upon: (i) maintain an active working relationship in the Telefónica Group at the date of the cycle's consolidation; and (ii) the achievement of results which represent the fulfillment of the objectives set for the plan. The level of success is based on the comparison of the evolution of shareholder remuneration considering price and dividends (Total Shareholder Return - TSR) of Telefónica share, vis-à-vis the evolution of TSRs corresponding to a number of companies quoted in the telecommunications industry, which correspond to the Comparison Group. The maximum number of shares allocated in the first open cycle on December 31, 2017 is as follows:

·Cycle 2014-2017: occurred in September 2017, and the distribution of shares did not occur, given that the minimum TRS set forth in the program was not achieved.

·Cycle 2015-2018: scheduled to occur in September 2018, with 113 executives of Telefônica Brasil having the potential right to receive 83,500 initial shares of Telefónica S.A., which, as of December 31, 2017, accrued R$1.3 million.

ITEM 7.        MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A.    Major Shareholders

In accordance with our bylaws, we have two classes of capital stock authorized and outstanding: common shares (ações ordinárias) and preferred shares (ações preferenciais). Our common shares have full voting rights. Our preferred shares have voting rights only under limited circumstances.

On October 31, 2016, Telefônica Brasil received a correspondence from the shareholder Telefónica Latinoamérica Holding, S.L. stating that Telefónica Internacional, S.A. transferred to them their entire stake in the Company, or 24.09% of the Company's capital, represented by 46,746,635 common shares (8.18% of such class) and 360,532,578 preferred shares (32.22% of such class). The transfer of shareholding was held due to a universal succession under an internal reorganization in the Telefónica Group, through which Telefónica Internacional, S.A. was merged into Telefónica Latinoamérica Holding, S.L.

On December 31, 2017, Telefónica S.A. owned 34.67% of our common shares, Telefónica Latinoamérica Holding, S.L. owned 8.18% of our common shares and SP Telecomunicações owned 51.46% of our common shares. Since Telefónica Latinoamérica Holding, S.L. is a wholly owned subsidiary of Telefónica and owns 60.60% of the equity share capital of SP Telecomunicações, Telefónica has effective control over 94.47% of our outstanding common shares. Accordingly, Telefónica has the ability to control the election of our Board of Directors and to determine the direction of our strategic and corporate policies. None of Telefónica, Telefónica Latinoamérica Holding, S.L. or SP Telecomunicações has any special voting rights beyond those ordinarily accompanying the ownership of our common and preferred shares.

Telefónica S.A.’s shares are traded on various stock exchanges, including exchanges in Madrid, Barcelona, Bilbao, Valencia, London, New York, Lima and Buenos Aires.

Telefónica is one of the largest telecommunications companies in the world in terms of market capitalization and number of customers. With its strong mobile, fixed and broadband networks, and its innovative portfolio of digital solutions, Telefónica is transforming itself into a “Digital Telco,” a company that will be even better placed to meet the needs of its customers and capture new revenue growth.

Due to the level of provisioning and based on its analysis of the individual cases, our management believes that no additional liabilities related to any legal proceedings will have a material effect on our financial condition or results of operations, other than as described below.

FUST, FUNTTEL, FISTEL e EBC

FUST – Universalization of Telecommunications Service

Writs of Mandamus filed separately by the fixed and mobile operators to recognize the right to include interconnection and EILD expenses in the FUST base for fixed services and interconnection revenue in the FUST base for mobile services.  We have questioned such charges and the proceedings are waiting to be tried in the court of appeals.

As a result, ANATEL registered various infractions to constitute tax credits and other revenues that were not obtained from the provision of telecommunication services, on which ANATEL believes FUST is due.

101

On December 31, 2017, the total aggregate amount under dispute was R$4,316.6 million.

In the opinion of our management and its legal advisors, the chance of loss in the foregoing proceedings is possible, and, consequently, we have not made any provisions in connection with these proceedings.

FUNTTEL – Fund for the Technological Development of Telecommunications

On December 31, 2017, the company was party to administrative and judicial proceedings, which are waiting to be tried at the lower administrative court and the court of appeals.

Such proceedings concern the collection of contributions to FUNTTEL on other revenues (not related to telecom services), as well as on income and expenses transferred to other operators (interconnection).

On December 31, 2017, the total aggregate amount under dispute was R$493.9 million. In the opinion of our management and its legal advisors, the chance of loss in the foregoing proceeding is possible, but not probable and, consequently, we have not made any provisions in connection with this proceeding.

FISTEL – Telecommunications Supervision Fund

Due extension of the effective license period to use telephone switches in connection with use of landline phone carriers and extension of the right to use radiofrequency in connection with wireless service (wireless carriers), ANATEL charges the Installation Inspection Fee, TFI.

This collection is based on ANATEL’s understanding that such extension would represent a taxable event for TFI. We understand that such collection is unjustified, and separately challenged the aforesaid fee in court. On December 31, 2017, total consolidated amount was R$2,556.4 million, without the respective deposit in full.

In the opinion of our management, the chance of loss in the foregoing proceeding is possible and, consequently, we have not made any provisions in connection with this proceeding.

Tax Contribution to Brazilian Communication Company (“Empresa Brasil de Comunicação – EBC”)

The Union representing telephone companies and mobile cellular services (“Sinditelebrasil”) has been discussed in courts about the legality of the tax contribution to “EBC” to development, public-broadcasting services established by Law No. 11.652/08.

Tax Assessments filed by the “ANATEL” (National Telecommunications Agency) in order to collect the Tax Contribution. On December 31, 2017, the total aggregate amount under dispute was R$279.3 million.

In the opinion of our management and our legal advisors, the chance of loss in the foregoing proceeding is possible and, consequently, we have not made any provisions in connection with this proceeding.

Labor Litigation

We are also a defendant in several legal proceedings filed by former employees and outsourced employees (alleging joint or several liability), who claim, among other things, deficient overtime payment, unequal compensation, retirement wage supplements, health and security hazard compensation, free extension of health plan benefits to retirees of Company; and proceedings regarding our outsourcing practices.

In addition, we are also a defendant in four public civil actions filed by the Federal Ministry of Labor, which concerns contracting third-party companies in order to perform services related to our core business. Although the likelihood of loss of such actions is “possible,” no value amount has been attributed because currently we are unable to calculate the total amount we will owe in the event we lose and, as a result, we have not recorded any amounts.

102

Civil Claims

There are several civil claims against the Company. We have recorded R$1.0 billion in provisions for these proceedings where the risks are deemed probable, including the civil proceedings described below:

·Expansion Plan–PEX. We are defendants in proceedings related to the possible right of individuals who purchased our shares in connection with our network expansion plan after 1996, to receive additional shares from us. These claims are in course through the various levels of the court system and the success rate in each proceeding is classified on a case-by-case basis according to the facts presented in each proceeding. For the proceedings in which the success rate is classified as “probable,” we’ve recorded a provision of R$ 324.2 million.

·The Company and/or its subsidiaries are defendants in various civil proceedings related to consumers claims both in administrative and judicial courts, specially about poor performance. On December 31, 2017, provisioned amounts totaled R$269.2 million (R$ 386.7 million on December 31, 2016).

·The Company and/or its subsidiaries are parties to various civil proceedings of non-consumer nature in administrative and judicial courts, all related to the ordinary course of business. On December 31, 2017, provisioned amounts totaled R$ 435.5 million (R$ 396.4 million on December 31, 2016).

There are other several civil claims against the Company for which the chance of loss is deemed possible and for which we have not recorded provisions, including:

·Pension Benefit Plan Spin-Off. Two Associations - Sistel Participants Association in São Paulo (ASTEL) and  - National Federation of Associations of Retirees and Pensioners and Participants in Pension Funds in Telecom (FENAPAS) filed distinct class actions – with the same object - against the Company, seeking the annulment of the spin-off of the PBS pension benefit plan, that occurred in 2000, and created the specific TELESP–PBS pension benefit plan, and corresponding allocation of resources resulted from the technical surplus and fiscal contingencies existing at that time. The success rate in both of the claims is deemed possible based on the opinion of our legal advisors. The amount involved in both cases cannot yet be determined until an expert appraisal report is conducted since it includes the spun-off portion of Sistel related to the telecommunication operators from the former “Telebrás System.” With respect to the class action filed by ASTEL, the action was ruled in favor of the Company by the lower court. ASTEL filed an appeal, which is awaiting a ruling. With respect to the class action filed by FENAPAS, both the lower and superior courts ruled against the Company. A new appeal of the Company to Superior Court is awaiting a ruling. 

·Class Action filed by SISTEL Participants’ Association (ASTEL) in the state of São Paulo, in which SISTEL associates question the changes made in the HealthCare Plan for Retired Employees (PAMA) of the Association and seek the reestablishment of the status quo. This proceeding is in the appeal phase. The amount cannot be estimated in that it entails a return to the prior conditions.

·The Company is party to other civil claims, at several Court levels, related to service rendering. Such claims have been filed by individual consumers, civil associations representing consumer rights or by the Bureau of Consumer Protection (PROCON), as well as by the Federal and State Public Prosecutor’s Office. The Company is also party to other claims of several types related to the normal course of business. On December 31, 2017, possible amounts totaled R$2,827 million (R$2,559 million on December 31, 2016).

·“TGLog is a party to an enforcement proceeding filed in the city of Barueri – SP due to an alleged default of transportation service bills. TGLog alleges that it made legitimate discounts due to contract breaches and losses arising from damages of goods and its customers, which are also subject matter of another proceeding. On December 31, 2017, the case amounted to R$0.2 million (R$1.2 million in December 31, 2016).”

• Terra Networks is part in (i) a claim proposed by a supplier of broadcast rights; (ii) annulment proceeding of penalties before the Consumer Protection Bureau (PROCON); (iii) Compensation Claims; (iv) collection of copyright (ECAD); and (v) claims proposed by former subscribers related to improper collection or breach of contract. On December 31, 2017, the total amount was R$17,340.

103

·The Company has received fines regarding the noncompliance with SAC Decree. We currently have various actions (administrative and judicial proceedings). On December 31 2017, amounts totaled R$14.2 million.

Ownership of Caller ID

Lune Projetos Especiais Telecomunicação Comércio e Ind. Ltda., a Brazilian company, filed on November 20, 2001 lawsuits against 23 wireless telecommunications operators, including TELESP Celular Participações and its subsidiaries. The lawsuits allege that those operators violated patent No. 9202624-9, related to Equipamento Controlador de Chamadas Entrantes e do Terminal do Usuário, or Caller ID, granted to Lune by the Brazilian Institute of Intellectual Property, or the INPI, on September 30, 1997. An unfavorable decision was handed down determining that the Company should refrain from selling mobile phones with Caller ID service, subject to a daily fine of R$10,000 in case of noncompliance. Furthermore, according to that decision, the Company must pay indemnification for royalties, to be calculated in settlement. Motions for Clarification were opposed by all parties and Lune’s motions for clarification were accepted since an injunctive relief in this stage of the proceedings was deemed applicable. A bill of review appeal was filed in view of the current decision which granted a stay of execution suspending that unfavorable decision until final judgment of the review. A bill of review was filed in view of the sentence handed down on June 30, 2016, by the 4th Chamber of the Court of Justice of the Federal District, in order to annul the lower court sentence and remit the proceedings back to the lower court for a new examination. We believe, based on the opinion of outside counsel that the likelihood of an unfavorable outcome with respect to Lune’s claim against us is possible. We are unable to determine at this time the extent of any potential liabilities with respect to this claim.

Expiration of Prepaid Plan Minutes

We and our subsidiaries, together with other Brazilian wireless telecommunications operators, are defendants in various lawsuits brought by the public prosecutor’s office and consumer protection associations challenging the imposition of a deadline for the use of purchased prepaid minutes. The plaintiffs allege that purchased prepaid minutes should not expire after any specified deadline. Conflicting decisions have been issued by the courts about this matter. Although we believe that our criteria for imposing the deadline is in compliance with ANATEL’s rules, we believe, based on the opinion of outside counsel, that the likelihood of an unfavorable outcome with respect to this claim is possible.

Regulatory and Antitrust Litigation

We are involved in several administrative and judicial proceedings relating to alleged breaches of obligations by ANATEL and CADE. As of December 31, 2017, amounts for those proceedings were R$6.2 billion, of which R$1.1 billion is provisioned.

Administrative and legal proceedings discussing payment of 2% charge on revenue from interconnection services due to the extension of right of use of SMP-related radiofrequencies. Under clause 1.7 of the Authorization Terms that grant right of use of SMP-related radio frequencies, the extension of right of use of such frequencies entails payment every two years, during the extension period (15 years), of a 2% charge calculated on net revenue from the basic and alternative service plans of the service company, determined in the year before that of payment. In the 15th year, the Company will pay 1% of its prior-year net revenue from the basic and alternative service plans. However, ANATEL determined that the 2% charge should be calculated on revenue from service plans and also on revenue from interconnection services and other operating income, which is not provided for by clause 1.7 of the referred to Authorization Terms. Considering that revenue from interconnection services should not be included in the calculation of the 2% charge for radiofrequency use right extension, the Company filed administrative and legal proceedings challenging these charges, based on ANATEL’s position.

104

Dividends and Dividend Distribution Policy

Priority and Amount of Preferred Dividends

The Brazilian Corporate Law determines that the shareholders of a company have the right to receive a minimum percentage of the distributable profits (mandatory dividends) comprising dividends and/or interest on shareholders’ equity, or distributable amount, of the corporation for each fiscal year. If such amount is not determined in the bylaws of the company, Brazilian Corporate Law specifies the criteria to determine the minimum amount of the dividend. See “Item 10. Additional Information—B. Memorandum and Articles of Association.” Moreover, each Brazilian company may issue new preferred shares for public distribution only if one of the following terms applies to the preferred shares: (i) the right to receive dividends equivalent to at least 25% of the adjusted net profit for the fiscal year, to be calculated in accordance with Article 202 of the Brazilian Corporate Law as follows: (a) priority in the receipt of dividends corresponding to at least 3% of the book value per share and (b) the right to an equal share of the profits attributable to the holders of common shares, after the holders of common shares have received a dividend equal to a minimum of 3% of the book value per share; or (ii) the right to receive dividends, at least 10% higher than those paid for each common shares; or (iii) tag-along rights of at least 80% of the price per share paid in the sale of control to be paid by the controlling shareholder and also including the right to receive dividends at least equal to the dividend paid to common shares.

According to our bylaws, we are required to distribute as dividends of each fiscal year ending on December 31, to the extent amounts are available, an aggregate amount equal to at least 25% of adjusted net income as a mandatory dividend. The annual dividend distributed to holders of our preferred shares is 10% higher than the dividend distributed to our common shareholders.

As per our bylaws, our board of directors may declare interim dividends based on (i) the accrued profits recorded in our semiannual financial statements; (ii) the accrued profits recorded in our quarterly financial statements or in our financial statements of shorter periods, provided that the total amounts of dividends paid up every six months does not exceed the total amount within the capital reserve determined per article 182 of Brazilian Corporate Law; and (iii) the amount recorded on the profit and loss account or profit reserve account on our last annual or semiannual financial statements.

Under the Brazilian Corporate Law, a company is allowed to withhold payment of the mandatory dividend in respect of common shares and preferred shares if:

·management and the fiscal board report to the shareholders meeting that the distribution would be incompatible with the financial circumstances of the company; and

·the shareholders ratify this decision at the shareholder’s meeting.

If that is the case:

·management must forward to the CVM within five days of the shareholders meeting an explanation justifying the decision at the shareholders meeting; and

·the profits that were not distributed are to be recorded as a special reserve and, if not absorbed by losses in subsequent fiscal years, are to be paid as dividends as soon as the company’s financial situation allows.

For the purposes of the Brazilian Corporate Law, net profits are defined as net income after income tax and social contribution for the fiscal year, net of any accumulated losses from prior fiscal years and any amounts allocated to beneficiary parties’, employees’ and management’s participation in a company’s profits and subscription bonuses.

Under Brazilian Corporate Law, adjusted net income is an amount equal to our net income adjusted to reflect allocations to or from (i) legal reserves, and (ii) contingency reserves for anticipated losses, if any.

At each annual shareholders meeting, the Board of Directors is required to suggest the allocation of net profits obtained during the preceding fiscal year. Under Brazilian Corporate Law, we are required to maintain a legal reserve, to which 5% of our net profits must be allocated for each fiscal year, until the reserve amounts to 20% of our paid-in capital. Net losses, if any, shall be deducted from accumulated profits, profit reserves and legal reserve, following this order.

105

Brazilian Corporate Law also provides for an additional allocation of net profits to special accounts, also to be recommended by management and subject to approval by shareholders at the annual shareholders meeting, including the amount of net profits that may be allocated to the contingency reserve for anticipated losses that are deemed probable in future years. Any amount so allocated in a previous year must be either:

·reversed in the fiscal year in which the loss was anticipated, if the loss does not in fact occur; or

·written-off if the anticipated loss occurs.

Net profits may also be allocated to the unrealized income reserve in case the total amount of mandatory dividends exceeds the amount of realized net income. Such allocation should also be suggested by management and subject to approval by shareholders at the shareholders meeting. For such purpose, realized income is the balance of net profits exceeding the sum of:

·the positive net result of equity adjustment; and

·earnings, revenues or net profits from transactions or the accounting of assets and liabilities at market value, whose financial realization term occurs after the end of the next fiscal year.

The amounts available for distribution are determined on the basis of financial statements prepared in accordance with the accounting practices adopted in Brazil.

If the minimum dividend to be paid to the holders of preferred shares is not paid for the period set forth in our bylaws, which in no event shall be longer than three years, the holders of preferred shares will be entitled to full voting rights until such dividend is paid in full.

Payment of Dividends

We are required by law and our bylaws to hold an annual shareholders meeting until April 30 of each year to approve, among other issues, the allocation of net profits earned during the preceding fiscal year and the declaration of dividends by decision of common shareholders, acting on the recommendation of the executive officers, as approved by the Board of Directors. The payment of annual dividends is based on the financial statements prepared for each fiscal year ending on December 31. Under the Brazilian Corporate Law, dividends are required to be paid within 60 days following the date the dividend is declared to the shareholders of record on the declaration date, unless a resolution by the shareholders sets forth another date of payment, which must occur before the end of the fiscal year.

A shareholder has a three-year period from the dividend payment date to claim dividends in respect of its shares, after which any unclaimed dividend distributions legally revert to us. Because our shares are issued in book-entry form, dividends with respect to any share are credited to the account holding the share and no action is required on part of the shareholder. We are not required to adjust the amount of paid-in capital for inflation.

If a shareholder is not a resident of Brazil, he or she must register with the Central Bank to be eligible to receive dividends, sales proceeds or other amounts with respect to his or her shares outside of Brazil. Our preferred shares underlying ADSs are held in Brazil by a Brazilian custodian, Citibank N.A., as the agent for the depositary, which is the registered owner of our shares.

Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the custodian on behalf of the depositary, which will then convert those proceeds into U.S. dollars and will provide for U.S. dollars to be delivered to the depositary for distribution to holders of ADSs. If the custodian is unable to immediately convert the Brazilian currency received as dividends into U.S. dollars, the amount of U.S. dollars payable to holders of ADSs may be adversely affected by devaluations of the Brazilian currency that occur before dividends are converted and remitted. Dividends in respect of the preferred shares paid to resident and non resident shareholders, including holders of ADSs, are not currently subject to Brazilian withholding tax.

106

Additional Payments on Shareholders’ Equity

Law No. 9,249, dated December 26, 1995, as amended, provides for distribution to shareholders of interest on shareholders’ equity, which may be computed against the amount of dividends to be distributed to the shareholders. A company may treat these payments as financial expenses for income tax and social contribution purposes. Currently, this interest is limited to the daily pro rata variation of the TJLP, a nominal long-term interest rate determined by the federal government that includes an inflation factor and cannot exceed the greater of:

·50% of net income (before deducting income taxes and the interest on shareholders’ equity) for the period in respect of which the payment is made, or

·50% of the sum of retained earnings and profit reserves.

Currently, any payment of interest in respect to preferred shares to shareholders (including the holders of ADSs) is subject to Brazilian withholding tax at a rate of 15%, or 25% in the case of a shareholder domiciled in a tax haven, and these payments may be included, at their net value, as part of any mandatory dividend. If payment of interest on shareholders equity is made for a beneficiary located outside of Brazil, the IOF tax triggers at a rate of zero. See “Item 10. Additional Information—E. Taxation—Brazilian Tax Considerations— Distributions of Interest on Shareholders’ Equity.”

We declare and pay dividends and/or interest on shareholders’ equity as required by Brazilian Corporate Law and our bylaws. The declaration of annual dividends, including dividends in excess of the mandatory distribution, requires approval by the vote of a majority of the holders of common shares, and depends on many factors. These factors include our results of operations, financial condition, cash requirements, future prospects and other factors deemed relevant by shareholders. Our shareholders have historically acted on these matters based on recommendations by the Board of Directors. Within the context of tax planning, we may determine in the future that it is to our benefit to distribute interest on shareholders’ equity.

The following table sets forth the dividends or interest on shareholders’ equity paid to holders of our common and preferred shares since 2013 in reais.

Regulation of Brazilian Securities Markets

The Brazilian securities market is regulated and supervised by the CMN (which has general authority over the stock exchanges and securities markets), as provided for by the Brazilian Securities Exchange Act and Brazilian Corporate Law. The CMN is responsible for supervising the CVM’s activities, granting licenses to brokerage firms to govern their incorporation and operation, and regulating foreign investment and exchange transactions, as provided for by the Brazilian Securities Exchange Act and Law No. 4,595 of December 31, 1964, as amended. These laws and regulations provide for, among other things, disclosure requirements to issuers of securities listed on stock exchanges, criminal sanctions for insider trading and price manipulation, protection of minority shareholders, the procedures for licensing and supervising brokerage firms and the governance of Brazilian stock exchanges.

Under Brazilian Corporate Law, a company is either publicly held and listed, a companhia aberta, or privately held and unlisted, a companhia fechada. All listed companies are registered with the CVM and are subject to reporting requirements to periodically disclose information and material facts. A company registered with the CVM is authorized to trade its securities either on the Brazilian exchange markets, including the B3, or in the Brazilian over-the-counter market. Shares of companies listed on B3 may not simultaneously trade on the Brazilian over-the-counter markets. The over-the-counter market consists of direct trades between persons in which a financial institution registered with the CVM serves as an intermediary. No special application, other than registration with the CVM (and, in case of organized over-the-counter markets, with the relevant over-the-counter market), is necessary for securities of a publicly held company to be traded in this market. To be listed on the B3, a company must apply for registration with the B3 and the CVM.

111

Trading in securities on the B3 may be suspended under a request from a company in anticipation of a material announcement. Trading in the securities of a particular company may also be suspended under the initiative of B3 or the CVM, among other reasons, due to the belief that the company has provided inadequate information regarding a material event or has provided inadequate responses to inquiries by the CVM or the B3.

Trading on the B3

B3 is a Brazilian publicly held company established in March 2017 when the securities, commodities and futures exchanges activities of BM&FBOVESPA were combined with the activities of CETIP, a provider of financial services for the organized OTC market. B3 is one of the world’s largest financial market infrastructure providers by market value. The services it offers rage from exchange trading, clearing and other post-trade services to registration of over-the-counter (OTC) transactions and of vehicle and real estate loans.

Trading on the exchange is conducted by authorized members. Trading sessions take place every business day, from 10:00 a.m. to 5:00 p.m. or from 10:00 a.m. to 6:00 p.m. during daylight savings time in Brazil, on an electronic trading system called Megabolsa. Trading is also conducted between 6:00 p.m. and 7:30 p.m., or between 7:00 p.m. and 8:30 p.m. during daylight savings time in Brazil, 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 traded by investors operating on the Internet.

To better control the excess of volatility in market conditions, B3 has adopted a “circuit breaker” system pursuant to which trading sessions may be suspended for a period of 30 minutes or one hour whenever the indices of these stock exchanges fall below the limits of 10% and 15%, respectively, compared to the index at the close of trading of the previous trading day. In the event the stock exchange index falls below the limit of 20% in comparison to the previous trading day, B3 may determine the suspension of trading sessions for a certain period to be defined at its sole discretion.

On December 31, 2017, the aggregate market capitalization of the 342 companies listed on B3 was approximately US$955.6 billion. Although all the outstanding shares of an exchange-listed company may trade on a Brazilian stock exchange, in most cases, less than half of the listed shares are actually available for trading by the public, the remainder being held by small groups of controlling entities or persons that rarely trade their shares. For this reason, data showing the total market capitalization of Brazilian stock exchanges tends to overstate the liquidity of the Brazilian equity securities market.

Corporate Governance Practices

We are a sociedade anônima, a corporation incorporated under the laws of Brazil, and are subject to the corporate governance provisions of the Brazilian Corporate Law. We comply with the regulatory requirements of the Brazilian Corporate Law regarding the independence of our Board of Directors, the establishment and composition of certain board committees and the adoption and disclosure of corporate governance guidelines.

We comply with several requirements of Brazilian and international laws to promote strong corporate governance, reduce investor uncertainties and enhance disclosure of material and other information.

With the approval of our Board of Directors and/or Officers, we implemented several measures over the last few years designed to improve our transparency and disclosure practices. We believe these measures will benefit our shareholders, and current and future investors as well as the marketplace in general. Among the measures we have implemented, we have:

·created a policy for disclosure of material facts or corporate actions and trading of our securities (Política de Divulgação de Ato ou Fato Relevante e de Negociação de Valores Mobiliários);

112

·created a policy for internal controls related to the Communication, Recording and Control of Financial and Accounting Information (Normativa sobre Registro, Comunicação e Controle de Informação Financeiro-Contábil);

·established the Service Quality and Marketing Committee;

·established the Control and Audit Committee;

·established the Nominations, Compensation and Corporate Governance Committee;

·established the Strategy Committee;

·enacted a procedure to receive and deal with reports of accounting and auditing fraud within the company (Canal de Denúncias);

·enacted a policy for prior approval of contracting audit services (Normativa sobre Aprovação Prévia de Serviços a serem Prestados pelo Auditor Externo);

·enacted a policy regarding responsible business dealings (Princípios de Negócio Responsável);

·enacted an Ethics Code in respect of handling financial information (Normas de Conduta para Financeiros);

·enected a policy regarding communication of information to the securities market (Normativa sobre Comunicação de Informação aos Mercados); and

·enacted a policy regarding the prevention and fight against corruption (Diretrizes de Prevenção e Combate à Corrupção).

As determined by the Brazilian Corporate Law, the annual cap for the aggregate compensation of the statutory Board of Directors and Board of Executive Officers is approved by our shareholders at a shareholders meeting. The Nominations, Compensation and Corporate Governance Committee provides information and recommendations to the Board of Directors regarding the criterion for compensation.

Our policy relating to insider trading is determined pursuant to our Política de Divulgação de Ato ou Fato Relevante e de Negociação de Valores Mobiliários in accordance with corporate law. Senior management and members of our Board of Directors and any other employee exposed to sensitive information are subject to the restrictions imposed by such rules. In addition to the prohibition on trading of our shares by such individuals when in possession of insider information, the rules establish blackout trading periods for those periods when insider information is available. In addition, the charter sets forth instructions for dealing with conflicts of interest and mandates disclosure of any such situation.

Code of Business Conduct and Ethics

Although adoption of a code of ethics is not required by Brazilian Corporate Law, we implemented a code of ethics regulating the conduct of our managers in connection with the registration and control of financial and accounting information and their access to privileged and nonpublic information and data to comply with the requirements of the Sarbanes-Oxley Act and NYSE rules. See “Item 16B. Code of Ethics.”

In addition to complying with the rules of corporate governance applicable to us under Brazilian law, we intend to gradually comply with substantially all of the new rules established by the NYSE and the SEC applicable to domestic U.S. companies that are qualified as controlled companies under NYSE rules.

B.    Memorandum and Articles of Association

The following information describes our common shares and preferred shares and provisions of our bylaws and of the Brazilian Corporate Law. This description is only a summary. You should read and refer to our bylaws (estatuto social) included as Exhibit 1.1 hereto.

Description of Our Bylaws

The following is a summary of the material provisions of our bylaws and of the Brazilian Corporate Law. In Brazil, a company’s bylaws (estatuto social) are the principal governing document of a corporation (sociedade por ações).

General

We are registered with the Board of Trade of São Paulo (Junta Comercial de São Paulo), or JUCESP, under No. 35.3.001588-14. We have been duly registered with the CVM under No. 17671 since August 19, 1998. Our headquarters are located in the city of São Paulo, state of São Paulo, Brazil. Our company has an undetermined period of existence.

As of December 31, 2017, we had outstanding share capital of R$63,571,415,865.09, comprised of 1,690,984,923 total shares, consisting of 571,644,217 issued common shares and 1,119,340,706 issued preferred shares. All of our outstanding share capital is fully paid. All of our shares are without par value. Under the Brazilian Corporate Law, and in accordance with Law 10,303/01 considering that we were a publicly held company before 2001, 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 1,850,000,000 common or preferred shares without amendment to our bylaws. Any increase of our share capital above that limit must be approved by a general extraordinary shareholders meeting.

As of December 31, 2017, 2,290,164 common shares were held by us (treasury shares) at a book value per share of R$41.13. As of December 31, 2017, 983 preferred shares were held by us (treasury shares) at a book value per share of R$41.13. As of the date of this annual report, there are no persons to whom any capital of company or any of our subsidiaries is under option or agreed conditionally or unconditionally to be put under option.

History of Share Capital

At a meeting held on March 25, 2015, the Board of Directors approved unanimously the realization of a Public Offering for the Primary Distribution of Common and Preferred Shares issued by the Company, all registered shares, without par value, free and clear of any liens or encumbrances, including in the form of American Depositary Shares (“ADSs”), represented by American Depositary Receipts, held simultaneously in Brazil and abroad, through a capital increase of the Company.

114

The capital increase was approved by the Board of Directors’ meeting held on April 27, 2015, amounting to R$15.8 billion, increasing the Company’s share capital from R$37.8 billion to R$53.6 billion through the issuance of 121,711,240 common shares, at an issue price of R$38.47 per unit, and 236,803,588 preferred shares, at an issue price of R$47.00 per unit. Common shares, preferred shares and ADSs issued as a result of this capital increase confer to their holders, as of April 28, 2015, date of disclosure of the Global Offering announcement of commencement, the same rights assigned respectively to the holders of common shares, preferred shares and ADSs, currently outstanding, under the Company’s Bylaws and the Brazilian Law of Corporations, fully participating in dividends and other distributions declared from the date of publication of the Global Offering announcement of commencement.

The issue price of R$47.00 per preferred share was determined after the completion of the bookbuilding process, in accordance with Article 23, paragraph 1, and Article 44 of CVM Instruction 400, and in accordance with the provisions of Article 170, paragraph 1, item III, of Law 6,404 of December 15, 1976, as amended. The issue price of R$38.47 per common share was determined based on the price per preferred share determined after the completion of the bookbuilding process, applying a discount of 18.14%, which represents the average price discount trading of the common shares issued by the Company in relation to the trading price of the preferred shares issued by the Company in the three months prior to March 26, 2015.

In addition, at a meeting held on April 30, 2015, the Board of Directors approved a second capital increase in connection with the Public Offering for the Primary Distribution of Shares, due to the exercise, by the Bank of America Merrill Lynch Banco Múltiplo S.A., of the option of over‐allotment of shares that was granted by the Company through the Coordination, Placement and Firm Guarantee of Settlement of Common and Preferred Shares Issued by Telefônica Brasil S.A., in accordance with Article 24 of CVM Instruction 400, of December 29, 2003, as amended, to meet the excess demand verified during the Offering. The Company’s share capital was increased in the amount of R$295.3 million, through the issuance of 6,282,660 preferred shares at the issue price of R$ 47.00 per unit, increasing the share capital of the Company to R$53.9 billion, represented by 503,046,911 common shares and 985,019,821 preferred shares.

Finally, on May 28, 2015, the General Shareholders’ Meeting approved the merger of shares issued by GVT Participações (“GVTPar”) by the Company and its implementation, with the conversion of GVTPar in a wholly owned subsidiary of the Company and the consequent increase in the Company’s capital in the amount of R$9.7 billion through the issue of 68,597,306 common shares and 134,320,885 preferred shares, all without par value, increasing the share capital of the Company to R$63.6 billion, as it stands at the date of this report.

Corporate Purposes

Under Article 2 of our bylaws, 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 whose business purpose is also related to the telecommunication industry in Brazil;

·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 engaging in activities of common interest;

·to perform study and research activities aimed at the development of the telecommunications sector;

115

·to enter into contracts and agreements with other telecommunications companies or other persons or entities to assure the operations of our services, with no loss of its attributions and responsibilities;

·to perform other activities related to those assigned by the Brazilian National Telecommunications Agency (Agência Nacional de Telecomunicações), or ANATEL; and

·to commercialize equipment and materials necessary or useful to telecommunications services.

Board of Directors

Under our bylaws, any matters subject to the approval of our board of directors (conselho de administração) can be approved only by the majority of votes of the present members of our board of directors with a majority of members currently in office. Under our bylaws, our board of directors may only deliberate if a majority of its members are present at a duly convened meeting and in the event of a tie, the Chairman of the Board of Director shall be the tie breaker.

Election of Directors

The members of our board of directors are elected at general meetings of shareholders for concurrent three-year (3) terms. The tenure of the members of the board of directors and of the Board of Executive Officers will be conditioned on such members signing the respective instrument of investiture and complying with applicable legal requirements.

Qualification of Directors

Brazilian Corporate Law no longer requires ownership of shares in order for a person to qualify as a member of the board of directors of a corporation. The Brazilian Corporate Law requires each of our executive officers to be residents of Brazil. Members of our board of directors are not required to be residents of Brazil; however, their tenure is conditioned on the appointment of a representative who resides in Brazil with powers to receive service of process in proceedings initiated against such member based on the corporate legislation, by means of a power-of-attorney valid for at least three years after the termination of the term of such director.

Fiduciary Duties and Conflicts of Interest

All members of our board of directors owe fiduciary duties to us and all of our shareholders.

Under the Brazilian Corporate Law and the Board of Directors’ internal rules, if one of our directors has a conflict of interest with our company in connection with any proposed transaction, such director may not vote in any decision of our board of directors regarding such transaction and must disclose the nature and extent of his conflicting interest for inclusion in the minutes of the applicable meeting. Brazilian Corporate Law sets forth similar conflict of interest rules applicable to executive officers.

Any transaction in which one of our directors or executive officers may have an interest can only be approved on reasonable and fair terms and conditions that are no more favorable than the terms and conditions prevailing in the market or offered by third parties. If any such transaction does not meet this requirement, then the Brazilian Corporate Law provides that the transaction may be nullified and the interested director or executive officer must return to us any benefits or other advantages that he obtained from, or as result of, such transaction. Under the Brazilian Corporate Law and upon the request of a shareholder who owns at least 5% of our total share capital, our directors and executive officers must disclose to our shareholders at the Annual Shareholders’ Meeting certain transactions and circumstances that may give rise to a conflict of interest. In addition, our company (through the approval of the majority of our share capital) or shareholders who own 5% 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.

116

Compensation

Under our bylaws, our common shareholders approve the annual cap for aggregate compensation payable to our directors, 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.

As per Brazilian Corporate Law the compensation payable to the members of the fiscal council shall not be less than 10% of the compensation of the company’s executive officers, not including other benefits listed in paragraph three of article 162 thereof.  

Mandatory Retirement

Neither the Brazilian Corporate Law nor our bylaws establish any mandatory retirement age for our directors or executive officers.

Share Capital

Under the Brazilian Corporate Law, since October 2001, as per Law 10,303, the number of issued and outstanding non-voting shares or shares with limited voting rights, such as our preferred shares, may not exceed fifty percent of our total outstanding share capital, and not two thirds. However, according to the same law, companies that were already incorporated before said law went into effect were permitted to maintain the previous requirements. Therefore, in accordance with Law 10,303/01, considering that we were a publicly held company incorporated before 2001, 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. They are given priority in the reimbursement of capital, without premium, and are entitled to receive a dividend 10% higher than that attributable to common shares. See “—Voting Rights” for information regarding the voting rights of our preferred shares and “—Dividends—Dividend Preference of Preferred Shares” for information regarding the distribution preferences of our preferred shares.

Shareholders’ Meetings

Under the Brazilian Corporate Law, we must hold an annual shareholders’ meeting until April 30 of each year in order to:

·approve or reject the financial statements approved by our board of directors, including any recommendation by our board of directors for the allocation of net profit and distribution of dividends;

·elect members of our board of directors (upon expiration of their three-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; and

·approve the monetary adjustment of our share capital.

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.

We convene our shareholders’ meetings, including our annual shareholders’ meeting, by publishing a notice in two Brazilian newspapers (the State official gazette and a major newspaper). On the first call of any meeting, the notice must be published no fewer than three times, beginning at least 15 calendar days prior to the scheduled meeting date. On the second call of any meeting, the notice must be published no fewer than three times, beginning at least 8 calendar days prior to the scheduled meeting date. For meetings involving deliberations described under article 136 of the Brazilian Corporate Law, the notice must be published at least 30 calendar days prior to the scheduled meeting date and on the second call at least 10 calendar days prior to the scheduled meeting date. The notice must contain the meeting’s place, date, time, agenda and, in the case of a proposed amendment to our bylaws, a description of the subject matter of the proposed amendment.

117

Our board of directors may convene shareholders’ meetings. Under the Brazilian Corporate Law, shareholders’ meetings also may be convened by our shareholders as follows:

·by any of our shareholders if, under certain circumstances set forth in the Brazilian Corporate Law, our directors do not convene a shareholders’ meeting required by law within 60 days;

·by shareholders holding at least 5% of our total share capital if, after a period of 8 days, our directors fail to call a shareholders’ meeting that has been requested by such shareholders by means of a duly reasoned request that indicates the subject matter; and

·by shareholders holding at least 5% of either our total voting share capital or our total non-voting share capital, if after a period of 8 days, our directors fail to call a shareholders’ meeting for the purpose of appointing a fiscal council that has been requested by such shareholders.

In addition, our fiscal council may convene an ordinary shareholders’ meeting if our board of directors does not convene an annual shareholders’ meeting within 30 days or an extraordinary shareholders’ meeting at any other time to consider any urgent and serious matters.

Each shareholders’ meeting is presided over by the president of the board of directors, who is responsible for choosing a secretary of the meeting. In case of absence of the president of the board of directors at the shareholders’ meeting, the shareholders may choose, among those present, the president and the secretary of the meeting. A shareholder may be represented at a shareholders’ meeting by an attorney-in-fact appointed by the shareholder less 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. To be admitted to a shareholders’ meeting, a person must produce proof of his or her shareholder status or a valid power of attorney, together with any other requirement provided for in the call notice.

In order to convene a shareholders’ meeting, shareholders representing at least 25% of our issued voting share capital must be present on first call. However, shareholders representing at least two thirds of our issued voting share capital must be present at a shareholders’ meeting called to amend our bylaws. If a quorum is not met, our board of directors may issue a second call by publishing a notice as described above at least 8 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.

Remote Voting

Pursuant to the CVM Instruction No. 561/15, that altered the CVM Instruction No. 481/09, the system of Remote Voting should be adopted by Brazilian companies for:  (i) an Ordinary General Shareholders’ Meeting; (ii) whenever an Extraordinary General Shareholders’ Meeting is called and occurs on the same date as an Ordinary General Shareholders’ Meeting; and (iii) whenever a Shareholders’ Meeting is called to elect the members of the Fiscal Board or of the Board of Directors, due to the requirements set forth in article 21-A, 1^st paragraph, item II of CVM Instruction No. 481/09. This system aims to facilitate the participation of the Company’s shareholders in its meetings. This instruction provides for the following:

118

·	the creation of a Remote Voting Bulletin (“Boletim de Voto a Distância”) through which the shareholders may exercise their right to vote prior to the date in which the shareholders’ meeting is held;
·	the possibility to include in the Remote Voting Bulletin a list of candidates and submit minority shareholders’ proposals, for deliberation at the shareholders’ meeting, upon satisfaction of certain criteria; and
·	the deadlines, procedures and means of transmitting the Remote Voting Bulletin.
In addition, listed companies are required to adopt certain measures regarding the voting process, including:
·	informing the market of the adoption of the cumulative voting process in shareholders’ meetings immediately upon receipt of the first valid requirement; and
·	disclosing voting maps, as well as any voting statement presented by a shareholder at a meeting;

In accordance with the provisions of applicable laws and regulations, Telefônica Brasil S.A. has adopted the Remote Voting System since its Annual Shareholders’ Meeting held on April 26, 2017.

Voting Rights

Under the Brazilian Corporate Law and our bylaws, each of our common shares entitles its holder to one vote at our shareholders’ meetings. Our preferred shares generally do not confer voting rights, except in limited circumstances described below. Holders of preferred shares are only entitled to attend and to discuss, but not to vote on, the issues discussed at our general shareholders’ meetings. Whenever the shares of any class are entitled to vote, each share is entitled to one vote.

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 account. Under the Brazilian Corporate Law, the approval of shareholders representing at least half of our voting shares is required for the types of action described below:

· creating preferred shares or disproportionately increasing an existing class of our preferred shares relative to the other classes of our preferred shares, other than to the extent permitted by our bylaws;

· changing a priority, preference, right, privilege or condition of redemption or amortization of any class of our preferred shares or creating 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;

· reducing the mandatory dividend set forth in our bylaws;

· changing our corporate purpose;

· merging our company with another company, or consolidating our company, subject to the conditions set forth in the Brazilian Corporate Law;

· transferring all of our shares to another company, known as an “incorporação de ações” under the Brazilian Corporate Law;

· participating in a centralized group of companies (grupo de sociedades) as defined under the Brazilian Corporate Law and subject to the conditions set forth in the Brazilian Corporate Law;

· dissolving or liquidating our company or canceling any ongoing liquidation of our company; and

· spinning-off of all or any part of our company.

119

Decisions on the transformation of our company into another form of business entity require the unanimous approval of our shareholders, including the holders of our preferred shares.

Our company is required to give effect to shareholders 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 or the power to control our company, if these agreements are filed with our headquarters. Brazilian Corporate Law requires the president of any shareholder or board of directors meeting to disregard any vote taken by any of the parties to any shareholders 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 shareholders 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 shareholders agreement have the right to vote the shares of the absent or abstaining shareholder (or on behalf of the absent director) in compliance with that shareholders agreement.

Under the Brazilian Corporate Law, neither our bylaws nor actions taken at a shareholders’ meeting may deprive any of our shareholders of certain specific rights, including:

·the right to participate in the distribution of our profits;

·the right to participate in any remaining residual assets in the event of our liquidation;

·the right to supervise the management of our corporate business as specified in the Brazilian Corporate Law;

·preemptive rights in the event of an issuance of our shares, debentures convertible into our shares or subscription bonuses, except with respect to a public offering of our securities; and

·the right to withdraw from our company under the circumstances specified in the Brazilian Corporate Law.

Voting Rights of Minority Shareholders

Shareholders holding shares representing not less than 5% of our voting shares at our shareholders’ meeting have the right to request that we adopt a cumulative voting procedure to elect the members of the board of directors. This procedure must be requested by the required number of shareholders at least 48 hours prior to a shareholders’ meeting.

Under the Brazilian Corporate Law, shareholders that are not controlling shareholders, but that together hold either:

·non-voting preferred shares representing at least 10% of our total share capital; or

·common shares representing at least 15% of our voting capital have the right to appoint one member to our board of directors at our shareholders’ meeting. 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 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 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.

The shareholders seeking to exercise these minority rights must prove that they have held their shares for not less than three (3) months preceding the shareholders’ meeting at which the director will be appointed. Brazilian Corporate Law provides that any directors appointed by the non−controlling shareholders have the right to veto for cause the selection of our independent registered public accounting firm.

120

In accordance with the Brazilian Corporate Law, the holders of preferred shares without voting rights or with restricted voting rights are entitled to elect one member and an alternate to our fiscal council in a separate election. Minority shareholders have the same right as long as they jointly represent 10% or more of the voting shares. The other shareholders with the right to vote may elect the remaining members and alternates, who, in any event, must outnumber the directors and alternates elected by the holders of the non-voting preferred shares and the minority shareholders.

Voting Rights of Preferred Shares

The appointment of one member of our statutory fiscal council takes places at the annual ordinary general shareholders’ meeting, upon separate vote of the holders of preferred shares, for the position available at the fiscal council. The election of a member of the board of directors by preferred shareholders also occurs on a separate vote, with no participation of the controlling shareholder.

Brazilian Corporate Law provides that certain non-voting shares, such as our preferred shares, shall be entitled to voting rights in the event a corporation fails for three consecutive fiscal years to pay any fixed or minimum dividends to which non-voting shares are entitled. In this case, the voting rights shall extend to these shares until the date on which the accrued and unpaid dividend is finally paid.

Preferred shares are entitled to full voting rights with respect to:

·the election of one member to the board of directors and fiscal council in a separate voting;

·amendments to our bylaw to suppress preferred shareholders’ voting right to select new Board members in a separate voting;

·any agreements for the rendering of management services (including technical assistance services) between us and any foreign entity related to our controlling shareholder;

·any agreements with related parties, in which the terms and conditions established are more onerous to our company than those normally adopted by the market in agreements of the same type;

·resolutions amending or revoking article 9, sole paragraph of Article 11, and article 30 of our bylaws; and

·any resolution submitted to the general shareholders meeting during our liquidation process.

Under the Brazilian Corporate Law, the following actions require ratification by the majority of issued and outstanding shares of the affected class within one year from the shareholders’ meeting at which the common shareholders approve the action:

·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 bylaws;

·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.

This meeting would be called by publication of a notice in two Brazilian newspapers during three days, at least 30 days before the meeting. However, it would not generally require any other form of notice.

Liquidation

We may be liquidated in accordance with the provisions of Brazilian law. In the event of our extrajudicial liquidation, a shareholders’ meeting will determine the manner of our liquidation, appoint our liquidator and our fiscal council that will function during the liquidation period.

121

Upon our liquidation, our preferred shares will be given preference in the reimbursement of capital, without premium.

Preemptive Rights

Each shareholder has a general preemptive right to subscribe for shares of the same class in any capital increase, in an amount sufficient to keep the same proportional participation of such shareholder in the total capital of the corporation. A minimum period of 30 days following the publication of the capital increase notice shall be observed by the corporation for the exercise of the preemptive right by the shareholder. The right of participation in capital increases is assignable under Brazilian Corporate Law. In the event of a capital increase that would maintain or increase the proportion of capital represented by preferred shares, holders of ADSs, or of preferred shares, would have the preemptive right to subscribe only to our newly issued preferred shares. In the event of a capital increase that would reduce the proportion of capital represented by preferred shares, holders of ADSs, or of preferred shares, would have the preemptive right to subscribe to our newly issued preferred shares in proportion to their shareholdings and to our newly issued common shares only to the extent necessary to prevent dilution of their interest.

However, 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. 

In addition, a publicly held company whose bylaws allow for capital increases may provide for the issuance of stock, debentures convertible into stock or subscription bonuses without granting any preemptive rights to prior shareholders or by decreasing the term for the shareholders to exercise their preemptive rights, as long as the placement of such securities is made:

·upon sale on a stock exchange or public subscription;

·through an exchange of shares in a public offering, with the purpose of acquiring control of another company; or

·for the use of certain tax incentives but only when such placement is made without granting preemptive rights.

Redemption, Amortization, Tender Offers and Rights of Withdrawal

Our bylaws 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 Corporate Law defines “redemption” (resgate de ações) as the payment of the value of the shares in order to permanently remove such shares from circulation, with or without a corresponding reduction of our share capital. The Brazilian Corporate Law defines “amortization” (amortização) as the distribution to the shareholders, without a corresponding capital reduction, of amounts that they would otherwise receive if 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 Corporate Law authorizes us to redeem shares not held by our controlling shareholders, if, after a tender offer effected as a consequence of delisting or a substantial reduction in the liquidity of our shares, our controlling shareholders 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 Corporate Law and our bylaws 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.”

122

Mandatory Tender Offers

The Brazilian Corporate Law requires the launching of a tender offer at a purchase price equal to fair value for all outstanding shares in order to cancel the registration of our company as a publicly held company or in case of a substantial reduction in the liquidity of our shares as a result of purchases by our controlling shareholders.

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 of the acquirer to launch a tender offer for the purchase of all our common shares for, at least, 80% of the 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 definitive documents of sale of the shares.

Rights of Withdrawal

The Brazilian Corporate 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 dissenting shareholders in the event that the holders of shares with voting rights authorize:

(i)    creating preferred shares or disproportionately increasing an existing class of our preferred shares relative to the other classes of our preferred shares, other than to the extent permitted by our bylaws;

(ii)   changing a priority, preference, right, privilege or condition of redemption or amortization of any class of our preferred shares or creating 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;

(iii)  reducing the mandatory dividend set forth in our bylaws;

(iv) a change in our corporate purpose;

(v)   merging our company with another company, or consolidating our company, subject to the conditions set forth in the Brazilian Corporate Law;

(vi) transferring all of our shares to another company, known as an “incorporação de ações” under the Brazilian Corporate Law;

(vii) participating in a centralized group of companies (grupo de sociedades) as defined under the Brazilian Corporate Law and subject to the conditions set forth in the Brazilian Corporate Law;

(viii) dissolving or liquidating our company or canceling any ongoing liquidation of our company;

(ix) spinning-off of all or any part of our company; and

(x) the inclusion of an arbitration clause in the company’s Bylaws.

In addition, we note that:

·in items (i) and (ii), only the holders of shares of the affected type or class will be entitled to redemption;

123

·in items (v) and (vii), the holders of shares of a type or class with liquidity and dispersion in the market will not have the right to redemption; and

·in item (ix), the dissenting shareholders shall only have a right of redemption if the spinning off implies in: (1) a change in the corporate 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, or (3) participation in a group of companies.

Dissenting 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 Corporate 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 abroad 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.

Only shareholders who own shares on the date of publication of the first notice convening the relevant shareholders’ meeting or the press release concerning the relevant transaction is published, whichever is earlier, will be entitled to withdrawal rights.

The redemption of shares arising out of the exercise of any withdrawal rights would be made at the book value per share, determined on the basis of our most recent audited balance sheet approved by our shareholders. If the shareholders’ meeting approving the action that gave rise to withdrawal rights occurred more than 60 days after the date of the most recent approved audited balance sheet, a shareholder may demand that its shares be valued on the basis of a balance sheet prepared specifically for this purpose.

The right of withdrawal lapses 30 days after the date of publication of the minutes of the shareholders’ meeting that approved the action that gave rise to withdrawal rights. Within ten days following the expiration of the term to exercise the withdrawal rights mentioned above, the company may call a Shareholders’ Meeting to confirm or reconsider any resolution giving rise to withdrawal if we believe that the withdrawal of shares of dissenting shareholders would jeopardize its financial stability.

Liability of Our Shareholders for Further Capital Calls

Neither Brazilian law nor our bylaws 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 bylaws, 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 controlling shareholders, directly or indirectly, (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 a material interest in our shares of any type and class 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.

124

CVM defines a “material interest” deal as any increase or decrease in share ownership of any class resulting in a change in the ownership levels of our shareholders. The ownership levels are set in 5% increments (for example, an acquisition where the total ownership of a shareholder jumps from 9% to 11% should be reported since it made the ownership surpass the 10% level). Ownership levels are calculated adding direct and indirect ownership and derivatives based upon our shares.

Our controlling shareholders, shareholders that appoint members of our board of directors or fiscal council and members of our board of directors, board of executive officers or fiscal council must file a statement reporting any change in their holdings of our shares, or of any family member or person included as dependent in their income tax return, or of our controlling shareholders (only if they are considered public companies), with the CVM and the Brazilian stock exchanges on which our securities are traded.

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 Corporate Law, which provides that a transfer of shares is effected by our transfer agent 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. 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 Central Bank pursuant to foreign investment regulations, the non-Brazilian investor is also required to amend, if necessary, through its local agent, the electronic certificate of registration to reflect the new ownership.

The B3 operates a central clearing system. 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 B3 (through a Brazilian institution that is duly authorized to operate by the Central Bank and maintains a clearing account with the clearing and settlement chamber of the B3). Shares subject to the custody of the clearing and settlement chamber of the B3 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 B3 and will be treated in the same manner as shareholders registered in our books.

Dividends

Our dividend distribution practice has historically included the distribution of periodic dividends, based on quarterly balance sheets or shorter periods approved by our board of directors. When we pay dividends on an annual basis, they are declared at our annual shareholders’ meeting, which we are required by the Brazilian Corporate Law and our bylaws to hold up to April 30 of each year. 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 until the end of the fiscal year. Under Article 9 of Law 9,249/95 and our bylaws, we also may pay interest attributable to shareholders’ equity as an alternative form of dividends upon approval of our board of directors.

Dividend Preference of Preferred Shares

Our preferred shares are entitled to receive a dividend 10% higher than that attributable to our common shares.

125

Payment of Dividends and Interest Attributable to Shareholders’ Equity (Juros sobre Capital Próprio)

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 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 preferred shares underlying our ADSs are held in Brazil by the depositary, which has registered with the Central Bank as the registered owner of our 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.

In addition, remittances are subject to a Brazilian financial transactions tax, which as of the date of this form 20-F is 0%, but may be subject to change.

For information about taxation on profits, dividends and interest on shareholders’ equity, see “—E. Taxation—Brazilian Tax Considerations—Taxation of Dividends.”

Dividends

We are required by the Brazilian Corporate Law and by our bylaws to hold an annual shareholders’ meeting until 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 Corporate 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.

Our board of directors may declare interim dividends based on (i) the accrued profits recorded in our semiannual financial statements; (ii) the accrued profits recorded in our quarterly financial statements or in our financial statements for shorter periods, provided that the total amount of dividends paid up every six months does not exceed the total amount within the capital reserve determined pursuant to article 182 of the Brazilian Corporate Law; and (iii) the amount recorded in the profit and loss account or profit reserve account in our last annual or semiannual financial statements.

All the interim dividends that are distributed shall be considered as part of the mandatory dividends that shall be paid by us.

Interest Attributable to Shareholders’ Equity

Brazilian corporations may make payments to shareholders characterized as interest on shareholders’ equity as an alternative form of making dividend distributions. Amounts paid as interest on shareholders’ equity (net of applicable withholding tax, as described below) may be deducted from the minimum dividends we are obligated to distribute to our shareholders in accordance with our bylaws and Brazilian Corporate Law. The rate of interest may not be higher than the federal government’s TJLP, as determined by the Central Bank from time to time (5.5% per annum for the first quarter of 2015, 6.0% per annum for the second quarter of 2015, 6.5% per annum for the third quarter of 2015, 7.0% per annum for the fourth quarter of 2015, 7.5% per annum for 2016 and for the first quarter of 2017, and 7.0% for the remaining quarters of 2017), applied over specific net equity accounts. The total amount distributed as interest on shareholders’ equity may not exceed the greater of (i) 50% of net income (before taking the distribution and any deductions for income taxes into account) for the year with respect to which the payment is made and (ii) 50% of retained earnings for the year before the year with respect to which the payment is made. Payments of interest on shareholders’ equity are decided by the shareholders on the basis of recommendations of our board of directors.

126

Distributions of interest on shareholders’ equity paid to Brazilian and non-Brazilian holders of preferred shares, including payments to the depositary in respect of preferred shares underlying ADSs, are deductible by us for Brazilian corporate income tax purposes. These payments to U.S. holders or other non-Brazilian holders are subject to Brazilian withholding tax at the rate of 15%. If the recipient of the payment is domiciled in a Tax Haven Jurisdiction, as defined by Brazilian law, the rate will be 25%.

Time Limits for Payments

Our shareholders have three (3) 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.

C.    Material Contracts

On June 30, 2011, ANATEL renewed our Fixed Switched Telephony Service (STFC) concession contract and consolidated them into two new contracts (each filed as an Exhibit to this Annual Report). One of these contracts authorizes the company to provide local telephone service (to the cities in Sector 31) and the other contract authorizes the company to provide long-distance telephone service (to and from Sector 31). These concession contracts will expire on December 31, 2025.

On December 6, 2016, the Brazilian Senate approved a law amending the General Telecommunications Law. When enacted, the new law will reformulate the entire telecommunications sector by converting public concession contracts into private authorization agreements. The private system has a less stringent set of commitments (e.g., there will be no expiration date). Once the President signs the bill into law, ANATEL will issue specific regulations on how the licenses will be adapted. 

We also have authorization to provide local and long-distance telephone services under the private system (all sectors, except Sector 31), granted in 2002, for an unlimited term. Telefônica Brasil has Multimedia Communication Service Authorization Terms, which are also material contracts. Based on these Authorization Terms, the companies may provide broadband services in the state of São Paulo (Telefônica) and all over Brazilian territory. The Terms were signed on April 17, 2003 and March 19, 2004 for an unlimited term and are still in effect. Telefônica has also Conditioned Access Service Authorization Terms for the provision of pay TV services. The Authorization Terms were transferred back to Telefônica Brasil in 2013, as a result of a corporate restructuring.

The General Plan of Authorization divided the country into three regions: Region I: States of Rio de Janeiro, Espírito Santo, Minas Gerais, Amazonas, Roraima, Amapá, Pará, Maranhão, Bahia, Sergipe, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas, Region II: States of Paraná, Santa Catarina, Rio Grande do Sul, Goiás, Tocantins, Mato Grosso do Sul, Mato Grosso, Rondônia, Acre and Federal District and Region III: only the State of São Paulo.

Telefônica signed Authorization Terms for the provision of Personal Mobile Services, SMP, with national coverage, in all three regions.

For Region I, the Terms of Service Authorization n.º 078/2012 of 07/02/2012; for Region II, the Terms of Service Authorization n.° 005/2010 of 29/01/2010; and for Region III, the Terms of Service Authorization n.° 006/2010 of 29/01/2010.

Licenses for personal mobile services (SMP) grant the right to provide mobile services for an unlimited term. However, the use of radiofrequency spectrum is restricted in accordance with specific license conditions:

License renewals for “A” and “B” bands must be requested within 30 months from the expiry date. Spectrum rights may be renewed only once, for a 15-year term. After this period, the license is renegotiated.

License renewals for the “E” band must be requested between 36 and 48 months in advance of the expiry date. Spectrum rights may be renewed only once, for a 15-year period. After this period, the license is renegotiated.

In December 2007, ANATEL auctioned off nationally 15 blocks in the 1900 MHz band (“L” band). Vivo (merged into Telefônica) won 13 of them throughout Brasil, except in the northern region and the towns of Londrina and Tamarana in the state of Paraná. Nevertheless, the Bidding Terms set forth the possibility of realigning the “L” band with the “J” band, maintaining the same conditions (including costs and expiry date) of the “J” band. In 2012, Telefônica requested and on August 27, 2013 ANATEL granted the “L” band realignment for the States of:

·Rio Grande do Sul, excluding the cities of Pelotas, Morro Redondo, Capão do Leão e Turuçu;

·Rio de Janeiro;

·Espírito Santo;

·Bahia and Vivo-Sergipe;

·Telefônica-São Paulo, excluding the cities of Altinópolis, Aramina, Batatais, Brodosqui, Buritizal, Cajuru, Cássia dos Coqueiros, Colômbia, Franca, Guaíra, Guará, Ipuã, Ituverava, Jardinópolis, Miguelópolis, Morro Agudo, Nuporanga, Orlândia, Ribeirão Corrente, Sales de Oliveira, Santa Cruz da Esperança, Santo Antônio da Alegria e São Joaquim da Barra;

In December 2010, ANATEL auctioned off 169 licenses in the 900 MHz, 1800 MHz and 2100 MHz frequencies. Vivo (merged into Telefônica) acquired 23 blocks, 14 in 1800 MHz frequency bands “D,” “E,” “M” and extension bands, and 9 in the 900 MHz extension bands. As a result, Telefônica has nationwide coverage in the 1800 MHz frequency band. The 23 blocks are:

·Extension of the 1800 MHz band in the cities of Londrina and Tamarana in the state of Paraná.

License for the 900MHz and 1800MHz band will expire in 2023. Renewal must be requested between 36 and 48 months in advance of the expiry date. Spectrum rights may be renewed only once, for a 15-year period.

In April 2012, ANATEL auctioned off 273 licenses in the 450 MHz, and 2500 MHz frequencies. Vivo (merged into Telefônica) secured 1 block in 2500 MHz frequency band “X” (20 + 20 MHz) nationwide, together with the right and obligation to use the 450 MHz frequency band in the States of Alagoas (AL), Ceará (CE), Minas Gerais (MG), Paraíba (PB), Pernambuco (PE), Piauí (PI), Rio Grande do Norte (RN) and Sergipe (SE), as well as the areas identified by the National Codes 13, 14, 15, 16, 17, 18 and 19, in the State of São Paulo (SP). Nonetheless, the commitment to use the 450 MHz band may also be fulfilled by the use of any other frequency range Telefônica already holds. See below the relevant expiration and renewal dates:

·Brasil (“X” Band – 2500 MHz) until 2027 (associated to SMP service) to be renewed in October 18, 2024;

·Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe (450 MHz) until 2027 (associated to STFC and SCM services) to be renewed in October 18, 2024;

·Telefônica in the areas identified by the National Codes 13, 14, 15, 16, 17, 18 and 19, in the state of São Paulo (SP), until 2027 (associated to SMP and SCM services) to be renewed in October 18, 2024.

In September 2014, ANATEL auctioned off 6 blocks in the 700 MHz frequency. We acquired 3 blocks resulting in nationwide coverage in the 700 MHz frequency band. The spectrum licenses may be renewed in 2029.

In December 2015, ANATEL auctioned off the remaining spectrum lots in the 1800 MHz, 1900 MHz, 2500 MHz and 3500 MHz bands, Telefônica acquired seven lots of the 2500 MHz frequency band. These lots are associated to six different States, five of them the capital cities of the States of São Paulo, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, and Tocantins and one city in the State of Mato Grosso do Sul. Such frequencies will be used for provision of 4G mobile services. The spectrum license may be for renewed in 2030.

The licenses above may be renewed; (i) only once; (ii) for an additional term of 15 (fifteen) years; and (iii) upon payment of 2% of our net revenues from usage charges in the applicable region in the previous year. The payment is also due every two years during the extension period.

D.    Exchange Controls

There are no restrictions on ownership of preferred shares or common shares by individuals or legal entities domiciled outside of Brazil, provided that they comply with the registration requirements set forth in the applicable regulation enacted by CMN and the CVM.

The right to convert dividend or interest payments and proceeds from the sale of shares into foreign currency and to remit such amounts outside Brazil is subject to restrictions under foreign investment legislation which generally requires, among other things, the documentary evidence that provides the validity and properly backs the economic grounds of the foreign exchange transaction and that the relevant investment be registered with the Central Bank and the CVM, as applicable. The restrictions on the remittance of foreign capital abroad may hinder or prevent the custodian for the preferred shares represented by ADSs or holders of preferred shares from converting dividends, distributions or the proceeds from any sale of these preferred shares into U.S. dollars and remitting the U.S. dollars abroad. Holders of ADSs could be adversely affected by delays in, or refusal to grant any, required government approval to convert Brazilian currency payments on the preferred shares underlying the ADSs and to remit the proceeds abroad.

131

As from March 30, 2015, the different forms of foreign portfolio investments in Brazil, including investments via Depositary Receipts, are regulated by CMN Resolution 4,373, of September 29, 2014 (“Resolution No. 4,373”), which revoked the former rule (CMN Resolution 2,689, of January 26, 2000) that had been in force for about 15 years.

Resolution No. 4,373 of the CMN provides for the issuance of Depositary Receipts in foreign markets in respect of shares of Brazilian issuers. The Depositary Receipts program shall be approved by Central Bank and CVM before the issuance of the Depositary Receipts. Accordingly, the proceeds from the sale of the Depositary Receipts by holders outside Brazil are free of Brazilian foreign investment controls, and holders of the Depositary Receipts may be entitled to favorable tax treatment. See “—E. Taxation—Brazilian Tax Considerations.”

Under Resolution No. 4,373 of the CMN, foreign investors registered with the CVM may buy and sell Brazilian securities, including the preferred shares, on Brazilian stock exchanges without obtaining separate certificates of registration for each transaction. The registered foreign investors may also be entitled to favorable tax treatment. See “—E. Taxation—Brazilian Tax Considerations.”

Pursuant to Resolution No. 4,373, an investor residing outside Brazil that is willing to invest pursuant to the mechanism described in the previous paragraph must: (i) appoint at least one financial institution or an institution authorized to operate by the Brazilian Central Bank as representative in Brazil that will be responsible for complying with the registration and reporting requirements and reporting procedures of the Brazilian Central Bank and the CVM; (ii) register as a foreign investor with the CVM; (iii) appoint one or more custodians authorized by CVM; (iv) register the foreign investment with the Brazilian Central Bank; (v) appoint a tax representative in Brazil; and (vi) obtain a taxpayer identification number from the Brazilian federal tax authorities

The securities and other financial assets held by a foreign investor pursuant to Resolution No. 4,373 must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or by the CVM. In addition, the trading of securities is in general restricted to transactions carried out on the Brazilian stock exchanges or over-the-counter markets licensed by the CVM.

Instruction CVM 560 of March 27, 2015, as amended, introduced in the Brazilian securities regulation the obligation of the representatives of investors residing outside Brazil to inform CVM the movements and application of funds of the investors participating in collective accounts and holders of own accounts represented by them.

Registered Capital

Amounts invested in preferred shares by a non-Brazilian holder who qualifies under Resolution No. 4,373 and obtains registration with the CVM, or by the depositary representing an ADS holder, are eligible for registration with the Central Bank. Such registration (the amount so registered is referred to as registered capital) allows remittances of funds outside Brazil converted into foreign currency at the commercial market rate, acquired with the proceeds of distributions on, and amounts realized through, dispositions of such preferred shares. The registered capital per preferred share purchased in the form of ADS, or purchased in Brazil and deposited with the depositary in exchange for ADS, will be equal to its purchase price (stated in U.S. dollars). The registered capital per preferred share withdrawn upon cancellation of an ADS will be the U.S. dollar equivalent of (i) the average price of a preferred share on the Brazilian stock exchange on which the most preferred shares were traded on the day of withdrawal or (ii) if no preferred shares were traded on that day, the average price on the Brazilian stock exchange on which the most preferred shares were traded in the 15 trading sessions immediately preceding such withdrawal. The U.S. dollar equivalent will be determined on the basis of the average commercial market rates (buy/sell) quoted by the Central Bank on such date or dates.

132

An electronic registration has been issued in the name of the depositary with respect to the ADSs and is maintained by the custodian on behalf of the depositary. Pursuant to the registration, the custodian and the depositary are able to convert dividends and other distributions with respect to the preferred shares represented by ADSs into foreign currency and remit the proceeds outside Brazil. If a holder of ADSs exchanges such ADSs for preferred shares, such holder will be entitled to continue to rely on the depositary’s registration for five business days after such exchange, following which such holder must seek to obtain its own electronic registration with the Central Bank. Thereafter, any holder of preferred shares may not be able to convert into foreign currency and remit outside Brazil the proceeds from the disposition of, or distributions with respect to, such preferred shares, unless such holder is a duly qualified investor under Resolution No. 4,373 and obtains its own electronic registration.

If the holder does not qualify under Resolution No. 4,373 by registering with the CVM and the Central Bank and appoints a representative in Brazil to act directly in the Brazilian market to acquire preferred shares, the holder will be subject to a less favorable Brazilian tax treatment than a holder of ADSs. Regardless of registration under Resolution No. 4,373, residents of tax havens are subject to less favorable tax treatment than other foreign investors. See “—E. Taxation—Brazilian Tax Considerations.”

Under current Brazilian legislation, the federal government may impose temporary restrictions on remittances of foreign capital abroad in the event of a serious imbalance or an anticipated serious imbalance of Brazil’s balance of payments. For approximately six months in 1989 and early 1990, the federal government froze all dividend and capital repatriations held by the Central Bank that were owed to foreign equity investors, to conserve Brazil’s foreign currency reserves. These amounts were subsequently released in accordance with federal government directives. There can be no assurance that the federal government will not impose similar restrictions on foreign repatriations in the future.

E.    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 preferred shares or ADSs by certain holders or beneficial owners, as described below. This summary is based upon the tax laws and regulations of Brazil and the United States as of the date of this annual report, which are subject to change, possibly with retroactive effect, and to differing interpretations. You should consult your own tax  advisers as to the Brazilian, U.S. federal or other tax consequences of the acquisition, ownership and disposition of preferred shares or ADSs, including, in particular, the effect of any state, local or non-U.S., non-Brazilian tax laws.

Although there is presently no income tax treaty entered into 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 preferred shares or ADSs. Brazil and the United States have, however, entered into a Tax Treaty Information Exchange Agreement, in order to establish an effective exchange of tax-relatedinformation between the two countries.

Brazilian Tax Considerations

The following discussion summarizes the principal Brazilian tax consequences of the ownership and disposition of preferred shares or ADSs by a non-Brazilian holder. This discussion does not address all of the Brazilian tax considerations that may be applicable to any particular non-Brazilian holder, and each non-Brazilian holder should consult its own tax adviser about the Brazilian tax consequences of investing in preferred shares or ADSs.

Taxation of Dividends

Dividends paid by us, including stock dividends and other dividends paid in property to the depositary in respect of the preferred shares underlying ADSs, or to a non-Brazilian holder in respect of the preferred shares, are currently exempted from withholding tax in Brazil to the extent that the dividends are paid out of profits generated on or after January 1, 1996. Dividends relating to profits generated prior to January 1, 1996 may be subject to Brazilian withholding tax at varying rates, depending on the year the profits were generated.

133

On May 13, 2014, Law No. 12,973 was enacted aiming at aligning the taxable basis of federal taxes with the accounting basis assessed based on IFRS, which were adopted as the Brazilian accounting standards in 2008. According to such law, which is generally in effect as of 2015, dividends distributed out of accounting profits generated in 2014 and exceeding taxable profits (ascertained in accordance with the prior rules) will be subject to withholding tax at rates of 15% or 25%, depending on the location of the foreign shareholder, unless the distributing corporation elected to be subject to Law No. 12,973 in 2014, in which case, the accounting profits and taxable profits would be the same and there would be no excess dividends. As we chose to apply the new taxation rules for periods beginning on or after January 1, 2014, dividends paidbyus that relate to profits generated on or after January 1, 2014 will not be subject to withholding tax.

Distributions of Interest on Capital

Brazilian corporations may make payments to shareholders characterized as interest on shareholders’ equity as an alternative form of making dividend distributions. Amounts paid as interest on shareholders’ equity (net of applicable withholding tax, as described below) may be treated as payments with respect to the dividends we are obligated to distribute to our shareholders in accordance with our bylaws and Brazilian Corporate Law. The rate of interest may not be higher than the federal government’s TJLP, as determined by the Central Bank from time to time, applied to the balances of specific net equity accounts maintained by us. The total amount distributed as interest on shareholders’ equity may not exceed the greater of (i) 50% of our net income (before taking into account the distribution itself or any deductions for income taxes) for the year with respect to which the payment is made and (ii) 50% of our retained earnings for the year before the year with respect to which the payment is made. Payments of interest on shareholders’ equity are decided by the shareholders on the basis of recommendations of our board of directors.

Distributions of interest on shareholders’ equity paid to Brazilian and non-Brazilian holders of preferred shares, including payments to the depositary in respect of preferred shares underlying ADSs, are deductible by us for Brazilian corporate income tax purposes. These payments to U.S. holders or other non-Brazilian holders are currently subject to Brazilian withholding tax at the rate of 15%. If the recipient of the payment is domiciled in a Tax Haven Jurisdiction, as defined by Brazilian law, the rate will be 25%.

Taxation of Gains

Except as discussed below, gains recognized on a disposition of assets located in Brazil, such as our preferred shares, by a non-Brazilian holder, are subject to withholding income tax in Brazil. This rule is applicable regardless of whether the disposition is conducted in Brazil or abroad and regardless of whether the disposition is made to an individual or entity resident or domiciled in Brazil.

As a general rule, capital gains realized as a result of a disposition transaction are the positive difference between the amount realized on the disposition of the asset and the respective acquisition cost.

Capital gains realized by non-Brazilian holders on the disposition of shares sold on the Brazilian stock exchange (which includes the transactions carried out on the organized over-the-counter market):

·are subject to the withholding income tax at a zero percent rate, when realized by a non-Brazilian holder that (i) has registered its investment in Brazil before the Central Bank under the rules of the Brazilian Monetary Counsel (a “Registered Holder”), and (ii) is not a “Tax Haven Holder” (an investor domiciled in a Tax Haven jurisdiction, as defined by Ordinance No. 1,037); and

·are subject to income tax at progressive rates ranging from 15% to 22.5% (for transactions executed after January 1, 2017) or at a flat rate of 15% (for transactions executed before January 1, 2017) when realized by (i) a non-Brazilian holder that is not a Registered Holder and is not a Tax Haven Holder; and

·are subject to income tax at a rate of 25% when realized by a Tax Haven Holder, even if the Holder is a Registered Holder.

134

In the cases above in which tax is due, if the gains are related to transactions conducted on the Brazilian non-organized over-the-counter market with intermediation, the withholding income tax of 0.005% (pre-payment) is also applicable and can be offset against any income tax due on the capital gain.

There can be no assurance that the current favorable tax treatment of Registered Holders that are not Tax Haven Holders will continue in the future.

Sale of ADSs by Non-Resident Holders to Other Non-Residents in Brazil

As mentioned above, gains derived from disposition of assets located in Brazil involving non-resident investors are subject to Brazilian income tax. Our understanding is that ADSs should not qualify as assets located in Brazil and, thus, should not be subject to the Brazilian withholding tax, considering that the ADSs are issued and registered abroad.

However, considering the general and unclear scope of this legislation and the absence of judicial guidance in respect thereof, we cannot assure prospective investors that such interpretation of this law will prevail in the courts of Brazil.

Gains on the Exchange of ADSs for Preferred Shares

Although there is no clear regulatory guidance, the exchange of ADSs for shares should not be subject to Brazilian tax if the shares are registered under CMN Resolution No. 4,373 and the respective holder is not a Tax Haven Holder. If the preferred shares are not so registered or the holder is a Tax Haven Holder, the deposit of preferred shares in exchange for ADSs may be subject to Brazilian capital gains tax at progressive rates ranging from 15% to 22.5% (if the exchange is executed after January 1, 2017) or at a flat rate of 15% (if the exchange is executed before January 1, 2017). Non-Brazilian holders may exchange ADSs for the underlying preferred shares, sell the preferred shares on a Brazilian stock exchange and remit abroad the proceeds of the sale within five business days from the date of exchange (in reliance on the depositary’s electronic registration), with no tax consequences.

Upon receipt of the underlying preferred shares in exchange for ADSs, non-Brazilian holders may elect to register with the Central Bank the U.S. dollar value of such preferred shares as a foreign portfolio investment under the rules of the Brazilian Monetary Counsel, which will entitle them to the special tax treatment for Registered Holders described above.

Alternatively, the non-Brazilian holder is also entitled to register with the Central Bank the U.S. dollar value of such preferred shares as a foreign direct investment under the rules of Law No. 4,131/62, in which case the respective sale would be subject to the tax treatment referred to under “—Taxation of Gains.”

Discussion on Tax Haven Jurisdictions

Until December 2008, under Brazilian tax laws, a “Tax Haven Jurisdiction” 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%. Some amendments were implemented in connection with the concept of Tax Haven Jurisdiction via the enactment of Law No. 11,727/08, in force as of January 2009, in order to include in the definition of Tax Haven Jurisdiction any  country or location which imposes restrictions on the disclosure of shareholding composition or the ownership of an investment.

Law No. 11,727/08 also introduced the concept of “privileged tax regime”, which is applicable in connection with transactions subject to Brazilian transfer pricing rules and also is applicable to thin capitalization/cross border interest deductibility rule.  The definition of “privileged tax regime” is broader than the  definition of Tax Haven Jurisdiction. Pursuant to Law No. 11,727/08, a privileged tax regime is a tax regime that (1) does not tax income or taxes it at a maximum rate lower than 20%; or (2) grants tax benefits to non-resident entities or individuals (a) without the requirement to carry out a substantial economic activity in the country or location or (b) contingent to the non-exercise of a substantial economic activity in the country or location; or (3) does not tax income earned outside of  such country or location or taxes such income at a maximum rate lower than 20%; or (4) does not allow access to information related to shareholding composition, ownership of assets and rights, or economic transactions that are carried out in such country or location.

135

In addition, on June 7, 2010, Brazilian Tax Authorities enacted Ordinance No. 1,037, as amended, listing (i) the countries and jurisdictions considered Tax Haven Jurisdictions, and (ii) the privileged tax regimes.

According to Section 24-B of Law No. 9,430, as included by Section 23 of Law No. 11.727/08, the Executive branch is empowered to reduce or reinstate the income tax rate of 20% as the element to define a Tax Haven Jurisdiction or a “privileged tax regime”. In December 2014, Ruling No. 488/2014 was published and established that the rate of 20% is reduced to 17% in connection with countries, locations and jurisdictions aligned with international tax transparency standards, as per a definition to be provided by Brazilian Federal Revenue Service.

In any scenario (transactions executed before or after 2017), if the nonresidents located in tax haven jurisdictions (a country which does not impose any income tax, which imposes it at a maximum rate lower than 20.0%, or in which the laws impose restrictions on the disclosure of ownership composition or securities ownership or the identification of the effective beneficiary of income attributed to nonresident holders, as listed in Normative Instruction 1,037/10) capital gain tax will be levied at the flat rate of 25%.

Although we believe that the best interpretation of the current tax legislation should lead to the conclusion that the above-mentioned “privileged tax regime” concept should apply solely for purposes of Brazilian transfer pricing and thin capitalization rules, we cannot be sure whether subsequent legislation or interpretation by the Brazilian tax authorities of the definition of a “privileged tax regime,” provided by Law No. 11,727, will also apply to a non-resident holder in respect of gains realized upon a disposition of ADSs.

Other Brazilian Taxes

There are no Brazilian inheritance, gift or succession taxes applicable to the ownership or disposition of the preferred shares or ADSs by a non-Brazilian holder except for gift and inheritance taxes levied by some States in Brazil on gifts made or inheritances bestowed by individuals or entities not resident or domiciled in Brazil or in the relevant state to individuals or entities that are resident or domiciled within such state in Brazil. There is no Brazilian stamp, issue, registration, or similar taxes or duties payable by holders of preferred shares or ADSs.

Tax on Foreign Exchange and Financial Transactions

Tax on Foreign Exchange Transactions (the “IOF/Exchange Tax”)

Brazilian law imposes the IOF/Exchange Tax on the conversion of reais into foreign currency and on the conversion of foreign currency into reais. Currently, for most exchange transactions, the rate of IOF/Exchange is 0.38%. Effective as of December 1, 2011, currency exchange transactions carried out for the inflow of funds in Brazil for investment made by a foreign investor are subject to IOF/Exchange at (i) a 0% rate in the case of variable income transactions carried out on the Brazilian stock, futures and commodities exchanges, as well as in the acquisitions of shares of Brazilian publicly held companies in public offerings or subscription of shares related to capital contributions, provided that the issuer company has registered its shares for trading in the stock exchange, and (ii) 0% for the outflow of resources from Brazil related to these type of investments, including payments of dividends and interest on shareholders’ equity and the repatriation of funds invested in the Brazilian market. Furthermore, the IOF/Exchange is currently levied at a 0% rate on the exchange of ADSs into shares. Nonetheless, the Brazilian government is permitted to increase the rate at any time to a maximum of 25%, but only in relation to future transactions.

Tax on Transactions Involving Bonds and Securities (“IOF/Bonds Tax”)

Brazilian law imposes the IOF/Bonds Tax on transactions involving bonds and securities, including those carried out on a Brazilian stock exchange. The rate of IOF/Bonds Tax applicable to transactions involving the deposit of preferred shares in exchange for ADSs is currently zero. The Brazilian government may increase this rate up to 1.5% per day, but only with respect to future transactions.

136

U.S. Federal Income Tax Considerations

The following are the material U.S. federal income tax consequences to U.S. Holders (as defined below) of owning and disposing of preferred shares or ADSs, but this is not a comprehensive description of all of the tax considerations that may be relevant to a particular person’s decision to hold such securities.  The discussion applies only to U.S. Holders that hold preferred shares or ADSs as capital assets for U.S. federal income tax purposes, and it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder’s particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986 (the “Code”) known as the Medicare contribution tax, the effects of any state, local or non-U.S. tax laws and tax consequences applicable to U.S. Holders subject to special rules, such as:

·certain financial institutions;

·dealers or traders in securities who use a mark-to-market method of tax accounting;

·persons holding preferred shares or ADSs as part of a hedge, “straddle,” integrated transaction or similar transaction;

·persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

·entities classified as partnerships or other pass-through entities for U.S. federal income tax purposes;

·tax-exempt organizations;

·regulated investment companies;

·real estate investment trusts;

·insurance companies;

·persons that own or are deemed to own 10% or more of our stock by vote or value;

·persons required for U.S. federal income tax purposes to conform the timing of income accruals to their financial statements under Section 451 of the Code;

·persons who acquired our preferred shares or ADSs pursuant to the exercise of any employee stock option or otherwise as compensation; or

·persons holding preferred shares or ADSs in connection with a trade or business conducted outside of the United States.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds preferred shares or ADSs, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding preferred shares or ADSs and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of holding and disposing of the preferred shares or ADSs.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed U.S. Treasury regulations, all as of the date hereof. These laws are subject to change, possibly on a retroactive basis. This discussion is also based in part on representations by the depositary and assumes that each obligation under the Deposit Agreement and any related agreement will be performed in accordance with its terms.

137

You are a “U.S. Holder” if, for U.S. federal income tax purposes, you are a beneficial owner of preferred shares or ADSs and you are:

·an individual citizen or resident of the United States;

·a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia; or

·an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

THE SUMMARY OF U.S. FEDERAL INCOME TAX CONSEQUENCES SET OUT BELOW IS INTENDED FOR GENERAL INFORMATION PURPOSES ONLY.  U.S. HOLDERS OF PREFERRED SHARES OR ADSs ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISERS WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF OWNING OR DISPOSING OF PREFERRED SHARES OR ADSs, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL, NON-U.S. AND OTHER TAX LAWS AND POSSIBLE CHANGES IN TAX LAWS.

In general, if you own ADSs, you will be treated as the owner of the underlying shares represented by those ADSs for U.S. federal income tax purposes. Accordingly, no gain or loss will be recognized if you exchange ADSs for the underlying shares represented by those ADSs.

The U.S. Treasury has expressed concerns that parties to whom American depositary shares are released before shares are delivered to the depositary (such practice, “pre-release”), or intermediaries in the chain of ownership between holders of American depositary shares and the issuer of the security underlying the American depositary shares, may be taking actions that are inconsistent with the claiming of foreign tax credits by holders of American depositary shares. Such actions would also be inconsistent with the claiming of the reduced rate of tax, described below, applicable to dividends received by certain non-corporate holders. Accordingly, the creditability of Brazilian taxes, and the availability of the reduced tax rate for dividends received by certain non-corporate holders, each described below, could be affected by actions taken by such parties or intermediaries.

This discussion assumes that we are not, and will not become, a passive foreign investment company, as described below.

Taxation of Distributions

Distributions paid on preferred shares or ADSs (including distributions to shareholders that are treated as interest on shareholders’ equity for Brazilian tax purposes) will generally be treated as dividends to the extent paid out of current or accumulated earnings and profits (as determined under U.S. federal income tax principles).  Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends. Subject to applicable limitations that may vary depending upon your circumstances and the discussion above regarding concerns expressed by the U.S. Treasury, dividends paid by “qualified foreign corporations” to certain non-corporate U.S. Holders are taxable at the rates applicable to long-term capital gains. A foreign corporation is treated as a “qualified foreign corporation” with respect to dividends paid on stock that is readily tradable on a securities market in the United States, such as the NYSE, where our ADSs are traded. You should consult your tax adviser regarding the availability of the reduced tax rate on dividends in your particular circumstances.

The amount of a dividend will include any amounts withheld in respect of Brazilian taxes.  The amount of the dividend will be treated as foreign-source dividend income to you and will not be eligible for the dividends-received deduction generally allowed to U.S. corporations under the Code. Dividends will be included in your income on the date of your, or in the case of ADSs, the depositary’s, receipt of the dividend. The amount of any dividend income paid in reais will be a U.S. dollar amount calculated by reference to the exchange rate in effect on the date of such receipt, regardless of whether the payment is in fact converted into U.S. dollars. If the dividend is converted into U.S. dollars on the date of receipt, you should not be required to recognize foreign currency gain or loss in respect of the dividend income. If the dividend is not converted into U.S. dollars on the date of receipt, you will have a basis in reais equal to the U.S. dollar value on the date of receipt. You may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

138

Subject to applicable limitations that may vary depending upon your circumstances and subject to the discussion above regarding concerns expressed by the U.S. Treasury, Brazilian income taxes withheld from dividends on preferred shares or ADSs will be creditable against your U.S. federal income tax liability. The rules governing foreign tax credits are complex, and, therefore, you should consult your tax adviser regarding the availability of foreign tax credits in your particular circumstances. In particular, a U.S. Holder may use foreign tax credits to offset only the portion of its U.S. tax liability that is attributable to foreign-source income. Instead of claiming a credit, you may, at your election, deduct such Brazilian taxes in computing your taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all taxes paid or accrued in the taxable year to foreign countries and possessions of the United States.

Sale, Redemption or Other Disposition of Preferred Shares or ADSs

For U.S. federal income tax purposes, gain or loss you realize on the sale, redemption or other disposition of preferred shares or ADSs will generally be capital gain or loss, and will generally be long-term capital gain or loss if you held the preferred shares or ADSs for more than one year, provided, in the case of a redemption of preferred shares, that you do not own, and are not deemed to own, any of our voting stock. The amount of your gain or loss will equal the difference between your tax basis in the preferred shares or ADSs disposed of and the amount realized on the disposition, in each case, as determined in U.S. dollars. If a Brazilian tax on gains is withheld on the sale or disposition of preferred shares or ADSs, a U.S. Holder’s amount realized will include the gross amount of the proceeds of such sale or disposition before deduction of the Brazilian tax. See “—Brazilian Tax Considerations—Taxation of Gains” for a description of when a disposition may be subject to taxation by Brazil.  Such gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. U.S. Holders should consult their tax advisers as to whether the Brazilian tax on gains may be creditable against their U.S. federal income tax on foreign-source income from other sources.

Other Brazilian Taxes

You should note that any Brazilian IOF/Exchange Tax (as discussed above under “—Brazilian Tax Considerations”) will not be a creditable foreign tax for U.S. federal income tax purposes, although you may be entitled to deduct such tax, subject to applicable limitations under U.S. law. You should consult your tax adviser regarding the U.S. federal income tax consequences of the payment of Brazilian IOF/Exchange Tax, including whether you may claim a deduction for such tax or should instead include the amount of tax paid in your initial basis in the preferred shares or ADSs.

139

Passive Foreign Investment Company Rules

We believe that we were not a “passive foreign investment company” (“PFIC”) for U.S. federal income tax purposes for our 2017 taxable year. However, because PFIC status depends on the composition of a company’s income and assets and the market value of its assets from time to time, there can be no assurance that we will not be a PFIC for any taxable year. If we were a PFIC for any taxable year during which a U.S. Holder held preferred shares or ADSs, gain recognized by such U.S. Holder on a sale or other disposition (including certain pledges) of the preferred shares or ADSs would be allocated ratably over the U.S. Holder’s holding period for the preferred shares or ADSs.  The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for such taxable year, and an interest charge would be imposed on the resulting tax liability. Further, to the extent that any distribution received by a U.S. Holder on its preferred shares or ADSs exceeded 125% of the average of the annual distributions on preferred shares or ADSs received by the U.S. Holder during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, that distribution would be subject to taxation in the same manner. Certain elections may be available that would result in alternative treatments (such as mark-to-market treatment) of the preferred shares or ADSs. U.S. Holders should consult their tax advisers to determine whether any of these elections would be available and, if so, what the consequences of the alternative treatments would be in their particular circumstances.  If we are a PFIC for any taxable year during which a U.S. Holder owns our preferred shares or ADSs, the U.S. Holder will generally be required to file Internal Revenue Service (“IRS”) Form 8621 with its annual U.S. federal income tax return, subject to certain exceptions.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting and may be subject to backup withholding, unless (i) you are a U.S. corporation or other exempt recipient or (ii) in the case of backup withholding, you provide a correct taxpayer identification number and certify that you are not subject to backup withholding. The amount of any backup withholding from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided that the required information is timely furnished to the IRS.

Certain U.S. Holders who are individuals or closely-held entities may be required to report information on IRS Form 8938 relating to their ownership of securities of a non-U.S. person, subject to certain exceptions (including an exception for securities held in certain accounts maintained by financial institutions, in which case the accounts may be reportable if maintained by a non-U.S. financial institution). U.S. Holders are urged to consult their tax advisers regarding the effect, if any, of these rules on their ownership and disposition of preferred shares or ADSs.

U.S. HOLDERS OF OUR PREFERRED SHARES OR ADSs SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THE BRAZILIAN, U.S. FEDERAL, STATE, LOCAL AND OTHER TAX CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF OUR PREFERRED SHARES OR ADSs BASED UPON THEIR PARTICULAR CIRCUMSTANCES.

I.     Subsidiary Information

Not applicable.

ITEM 11.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to several market risks as a result of our commercial operations, debts obtained to finance our activities and financial derivative instruments, including exchange rate risk, interest rate risk, debt acceleration risk and credit risk. To help us manage our risks, we conduct a valuation of our financial assets and liabilities in relation to market values based on available information and appropriate valuation methodologies. However, the interpretation of market information, as well as the selection of methodologies, requires considerable judgment and reasonable estimates to produce adequate realization values. As a result, our valuation estimates do not necessarily indicate the amounts, which will be realized in the current market. The use of different market approaches and/or methodologies for the estimates may have a significant effect on the estimated realization values.

We also enter into derivative instruments to manage the risks to which we are exposed in accordance with our risk management policy. We do not hold derivative instruments for speculative purposes.

To further assist our risk management, we conduct fair value analyses of our derivative financials instruments, as well as sensitivity analyses of our risk variables and our net exposure risk. For more details of the results of our valuation analysis, risk management strategies, and sensitivity analysis of our derivative financial instruments, please see Note 33 to our consolidated financial statements.

The depositary, Citibank N.A., collects its fees for 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 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, receiving distributions or holding ADSs on the applicable record date, as applicable, must pay:	For:
Up to US$5.00 per 100 ADSs (or fraction thereof) issued	·Issuance of ADSs upon deposit of Shares, excluding issuances as a result of distributions

142

On January 28, 2013, we entered into a deposit agreement with Citibank N.A., pursuant to which Citibank N.A. became our depositary.

Citibank N.A. has agreed to reimburse us for expenses related to establishment and maintenance expenses of the ADS program. The depositary has agreed to reimburse us for our continuing annual stock exchange listing fees. The depositary has also agreed to pay 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. It has also agreed to reimburse us annually for certain investor relations programs or special investor relations promotional activities. In certain instances, the depositary has agreed to provide additional payments to us based on any applicable performance indicators relating to the ADR facility. 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 2017, we received from Citibank N.A., our depositary, US$2.7 million, for the services described above.

None.

ITEM 15.      CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, are responsible for establishing and maintaining our disclosure controls and procedures. These controls and procedures were designed to ensure that information relating to us required to be disclosed in the reports that we file under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We evaluated these disclosure controls and procedures under the supervision of our CEO and CFO as of December 31, 2017. Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were adequate and effective and were designed to ensure that material information relating to us and our consolidated subsidiaries are made known to them by others within those entities to allow timely decisions relating to the required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). The Telefônica Brasil internal control system was designed to provide reasonable assurance as to the integrity and reliability of the published financial statements. All internal control systems, no matter how well designed, may have inherent limitations and can provide reasonable assurance that the objectives of the control system are met.

Management evaluated the effectiveness of internal control over financial reporting under the supervision of our Chief Executive Officer, or CEO and Chief Financial Officer or CFO as of December 31, 2017 based on the criteria set out in the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) framework, or the 2013 framework, and concluded that, as of December 31, 2017, our internal control over financial reporting was adequate and effective.

Report of the Registered Public Accounting Firm

PricewaterhouseCoopers Auditores Independentes, the independent registered public accounting firm that has audited our consolidated financial statements, has issued a report on the effectiveness of our internal control over financial reporting as of December 31, 2017. This report appears on page F-3.

Changes in Internal Control over Financial Reporting

Our internal audit department periodically evaluates our internal controls for the main cycles, documenting by flow charts the processes used in each cycle, identifying opportunities and suggesting improvements for the existing control mechanisms. There was no change in our internal control over financial reporting that occurred during the period covered by this annual report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 16.      [RESERVED]

ITEM 16A.   AUDIT COMMITTEE FINANCIAL EXPERT

Our Control and Audit Committee is comprised of a minimum of three (3) and a maximum of five (5) nonexecutive directors. See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Control and Audit Committee.” Our Board of Directors has designated José María Del Rey Osorio, an independent member of our Board of Directors under Brazilian rules and a member of our Control and Audit Committee, as the Company’s “audit committee financial expert,” as such term is defined by the SEC. There are some similar functions between the Control and Audit Committee and our statutory Fiscal Board (Conselho Fiscal), the latter of which meets the requirements of the general exemption from the listing standards for audit committees set forth in Exchange Act Rule 10A-3(c)(3). See “Item 16D. Exemptions from the Listing Standards for Audit Committees Procedures.”

ITEM 16B.   CODE OF ETHICS

Our administration’s ethics conduct, as our employees’ daily performance is governed by a code of business conduct and ethics called the “Princípios de Negócio Responsável” or the Telefónica Business Principles – Telefônica’s code of ethics. Its global guidelines define the way we do business with all stakeholders and generate long term value to our shareholders and society as a whole. In addition, the Business Principles set forth mechanisms for decision making when facing ethical dilemmas and situations that eventually are not in accordance with the law. We promote periodical training to our employees aiming to reinforce our code of ethics’ (PNR) concepts and principles reaching 100% of our personnel.

The Compliance Department’s mission is to be a role model in ensuring applicability of anti-corruption compliance law and corporate ethics, generating value to stakeholders, protecting the company and its employees, reducing risks of non-compliance and increasing even more Telefônica’s culture which is based on ethics and integrity. The Compliance Department works together with other areas of the company to maintain our business excellence.

At Telefônica Brasil, the compliance program, named as #VivoDeAcordo, has important pillars to its solid implementation: total commitment from top management; a robust structure of highly qualified and skilled employees responsible for the program’s actions; regular analysis and evaluation of business risks; internal policies addressing diverse subjects, such as prevention of corruption, information security, gifts and entertainment, among others, in line with global guidelines and internal regulations well-structured and available to all employees; periodic compliance trainings for current and new employees and an active channel to answer questions about the entire program.

The program applies to all employees (including directors and board members) and also to allies through prevention, detection, remediation and integrity actions, such as through regular communication about the program for Telefônica’s stakeholders, anticorruption training on applicable laws, including the FCPA, policies available in our intranet portal, compliance channel among others.

   The company is aware of the importance of its supply chain for its international presence, the impact and involved values in its business transactions volume. For this reason, Telefonica promotes, establishes and maintains high level of legal duties with respect of its suppliers, promoting among them not only compliance quality/service standards, but also ethical, social, environmental and privacy standards in any relationship with Telefônica’s supply chain.

 As one of the pillars of our code of ethics (Princípios de Negócio Responsável), the respect and commitment to human rights guide regular and periodic evaluation of the impacts in our value chain. We conduct periodic risk assessment to identify, mitigate and manage compliance risks under the orientation of the UN’s framework “protect, respect and remedy.” 

The Telefónica Business Principles are available and open to consultation for employees on the Telefónica Intranet site as well as for the general public on the Telefónica external website (https://www.telefonica.com/en/web/about_telefonica/strategy/business-principles). These Business Principles were modified in 2017 in order to include, among others, several new principles related to privacy and data protection, security, responsible communication practices, the protection of minority shareholders as well as to reinforce other principles including the anti-corruption principle. No waivers were granted in 2017.

ITEM 16C.   PRINCIPAL ACCOUNTANT FEES AND SERVICES

In the chart below we have detailed: (1) the expenses accrued in respect of the fees for services rendered by PricewaterhouseCoopers Auditores Independentes, our independent auditor for the fiscal years ended December 31, 2017; and (2) the expenses accrued in respect of the fees for services rendered by Ernst & Young Auditores Independentes S.S., our independent auditor for the fiscal years ended December 31, 2016 and December 31, 2015:

145

	2017	2016	2015
	(in millions of reais)
Audit Fees	10.5	12.3	8.9
Audit-Related Fees	0.3	0.3	1.5
Total	10.8	12.6	10.4

Audit Fees

Services included under this heading are mainly the audit of the annual and reviews of interim financial statements, work to comply with the requirements of the Sarbanes-Oxley Act (Section 404) and the review of the 20-F report to be filed with US Securities and Exchange Commission (SEC).

Audit-Related Fees

This heading mainly includes services related to the review of the information required by regulatory authorities and the review of corporate responsibility reports.

ITEM 16D.   EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES PROCEDURES

Brazilian Corporate Law requires that we have a statutory Fiscal Board (Conselho Fiscal). We are relying on the general exemption from the listing standards relating to audit committees contained in Rule 10A-3(c)(3) under the Exchange Act because our statutory Fiscal Board meets the requirements of the general exemption set forth in Exchange Act Rule 10A-3(c)(3). See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Fiscal Board.” Our statutory Fiscal Board is primarily charged with certain advisory, oversight and review functions with respect to the company’s financial statements; however, the statutory Fiscal Board, as required by Brazilian Corporate Law, has only an advisory role and does not participate in the management of the company. Indeed, decisions of the statutory Fiscal Board are not binding on the company under Brazilian Corporate Law. Our Board of Directors, under Brazilian Corporate Law, is the only entity with the legal capacity to appoint and retain any independent registered public accounting firm, and decide the budget appropriation with respect to such auditors.

Since Brazilian Corporate Law does not specifically grant our statutory Fiscal Board the power to establish receipt, retention and complaint procedures regarding accounting, internal control and audit matters, or create policies for the confidential, anonymous treatment of employee concerns regarding accounting or auditing matters, we have established a Control and Audit Committee as a best corporate governance practice to address these various issues. See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Control and Audit Committee.”

We do not believe that our use of a fiscal board in accordance with Brazilian Corporate Law in combination with our Control and Audit Committee, as opposed to the provisions set forth in Exchange Act Rule 10A-3(b), materially adversely affects the ability of the Fiscal Board to act independently, satisfy the other applicable requirements of Exchange Act Rule 10A-3 or to fulfill its fiduciary and other obligations under Brazilian law.

ITEM 16G.  CORPORATE GOVERNANCE

Principal Differences Between U.S. and Brazilian Corporate Governance Practices

Pursuant to NYSE rules, foreign private issuers that are listed on the NYSE, such as our company, must disclose any significant ways in which their corporate governance practices differ from those followed by U.S. companies under the listing rules of the NYSE.

The significant differences between our corporate governance practices and the NYSE corporate governance standards are as follows:

147

Independence of Directors and Independence Tests

The NYSE standards require a majority of the membership of listed company boards to be composed of independent directors and set for the criteria for determining independence. However, controlled companies (whether or not they are foreign private issuers) are not required to have a majority of the members of their board of directors be independent. Therefore, we would be exempt from this NYSE requirement even if we were a U.S. company.

The Brazilian Corporate Law and our bylaws require that our directors be elected by our shareholders at a general shareholders meeting. Ten of our directors were appointed by our common shareholders, and one director was appointed by representatives of our minority preferred shareholders. Seven of our directors are independent in accordance with the rules of B3’s Novo Mercado.

Both the Brazilian Corporate Law and the CVM establish rules in relation to certain qualification requirements and restrictions, investiture, compensation, duties and responsibilities of companies’ executives and directors. We believe these rules provide adequate assurances that our independent directors are independent, although such rules permit us to have directors that would not otherwise pass the independence tests established by the NYSE.

Executive Sessions

The NYSE standards require non-management directors of listed companies to meet at regularly scheduled executive sessions without management. In addition, our Board of Directors’ internal rules set forth that the secretary of the Board of Directors shall summon regular meetings or sessions without the attendance of members of the Company's Board of Executive Officers even if they are member of the Board of Directors.

According to the Brazilian Corporate Law, up to one third of the members of our Board of Directors can be elected to executive positions. The remaining non-management directors are not expressly empowered to serve as a check on management, and there is no requirement that those directors meet regularly without management. Notwithstanding, our Board of Directors consists of eleven non-management directors.

Nominating/Corporate Governance Committee Requirements

The NYSE standards require that listed companies have a nominating/corporate governance committee composed entirely of independent directors, and such committee must have a written charter that addresses the committee’s purposes and responsibilities (including certain required purposes and responsibilities) as well as the annual performance evaluation of the committee. However, controlled companies (whether or not they are foreign private issuers) are exempt this requirement. Therefore, we would be exempt from this NYSE requirement even if we were a U.S. company.

Brazilian Corporate Law does not require us to maintain a committee responsible for nominations or corporate governance. Nevertheless, our Board of Directors has created our Nominations, Compensation and Corporate Governance Committee, which consists of three to five directors appointed by the Board of Directors to serve for the duration of their respective terms as members of the Board of Directors, two of which are independent in accordance with rules generally accepted in Brazil. Our Nominations, Compensation and Corporate Governance Committee has a written charter, which sets forth its responsibilities, including nominating our management team and setting compensation limits for our management, establishing employment agreements for our management and setting forth our annual report of corporate governance practices. Unlike the nominating/corporate governance committees of U.S. companies listed on the NYSE (other than controlled companies), our Nominations, Compensation and Corporate Governance Committee is not responsible for identifying individuals to become board members, or overseeing the evaluation of the board and management. See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Nominations, Compensation and Corporate Governance Committee” for a description of the responsibilities of our Nominations, Compensation and Corporate Governance Committee.

148

Compensation Committee Requirements

The NYSE standards require listed companies to have a compensation committee composed entirely of independent directors, and such members must meet the additional independence requirements specific to compensation committee membership set forth in the rules. In addition, NYSE standards require the compensation committee to have a written charter that addresses the committee’s purposes and responsibilities (including certain required purposes and responsibilities). In addition, the charter must specify the rights and responsibilities of the compensation committee regarding the authority to retain advisors and provide funding for such advisors. Certain specified factors must be considered regarding such advisers’ independence from management. However, controlled companies (whether or not they are foreign private issuers) are exempt this requirement. Therefore, we would be exempt from this NYSE requirement even if we were a U.S. company.

As noted above, while Brazilian Corporate Law does not require us to have a compensation committee, our Board of Directors has created our Nominations, Compensation and Corporate Governance Committee. As determined by the Brazilian Corporate Law, the compensation of management is approved by our shareholders at our shareholders’ meeting. Subject to this approval, our Board of Directors establishes the compensation of its members and of our executive officers.  The Nominations, Compensation and Corporate Governance Committee provides information and recommendations to the board of directors regarding compensation of our executive officers and managers. Our Nominations, Compensation and Corporate Governance Committee is not required to perform certain functions that are required of U.S. companies listed on the NYSE (other than controlled companies), such as directly reviewing and approving corporate goals and objectives relating to CEO compensation, evaluating the CEO’s performance in light of those goals and objectives and, either as a committee or together with the other independent directors, determining and approving the CEO’s compensation level based on this evaluation.

 Our Nominations, Compensation and Corporate Governance Committee is not required by the Brazilian Corporate Law or its charter to take into consideration any factors relevant to independence from management when retaining the advice of a compensation consultant, legal counsel or other adviser.

Audit Committee Requirements

The NYSE standards require listed companies (including foreign private issuers) to have an audit committee that satisfies the requirements of Rule 10A-3 under the Exchange Act. However, Rule 10A-3 provides an exemption for companies, such as our company, that have a board of auditors or statutory auditors, established and selected pursuant to home country legal provisions expressly requiring or permitting such a board or similar body, provided that certain criteria are satisfied. The NYSE standards also set forth additional requirements for the audit committees of listed companies, including that the audit committee must have a minimum of three members, all members of the audit committee must be independent, the audit committee must have a written charter that addresses certain topics, and each listed company must have an internal audit function. As a foreign private issuer, we are exempt from these additional requirements.

Brazilian Corporate Law and our bylaws each require that we have a statutory Fiscal Board (Conselho Fiscal). See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Fiscal Board.” Our statutory Fiscal Board meets the requirements of the general exemption from the listing standards for audit committees set forth in Exchange Act Rule 10A-3(c)(3). See “Item 16D. Exemptions from the Listing Standards for Audit Committees Procedures.” Our statutory Fiscal Board is primarily charged with certain advisory, oversight and review functions with respect to the company’s financial statements. However, the statutory Fiscal Board, as required by Brazilian Corporate Law, has only an advisory role and does not participate in the management of the company. Indeed, decisions of the statutory Fiscal Board are not binding on the company under Brazilian Corporate Law. See “Item 6. Directors, Senior Management and Employees—C. Board Practices—Fiscal Board.”

In addition to our statutory Fiscal Board, we have established a Control and Audit Committee as a best corporate governance practice to comply with the requirements of the Sarbanes-Oxley Act as described in “Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Control and Audit Committee.” Our Control and Audit Committee and comprises a minimum of three and a maximum of five directors, who are not members of our Board of Executive Officers, and who are appointed by the Board of Directors to serve as members of the Control and Audit Committee for the duration of their respective terms as members of the Board of Directors. All members of the Audit Committee are considered independent in accordance with rules generally accepted in Brazil. The Committee has its own charter, which was approved by the Board of Directors.

149

Shareholder Approval of Equity Compensation Plans

NYSE rules require that shareholders be given the opportunity to vote on all equity compensation plans and material revisions thereto, with limited exceptions. Neither Brazilian Corporate Law nor our bylaws require that our preferred shareholders approve of equity compensation plans.

Corporate Governance Guidelines

NYSE rules require that listed companies adopt and disclose corporate governance guidelines.

We are subject to the corporate governance provisions of the Brazilian Corporate Law and of CVM Instruction 480 (as amended by CVM Instruction 586 issued on June 8, 2017), which requires us to disclose certain corporate governance guidelines. Under CVM Instruction 480, we must disclose information regarding our adoption of the governance practices set forth in the Brazilian Corporate Governance Code - Public Companies (the “Governance Code”).  Thus, we are required to disclose a report named “Report on the Brazilian Corporate Governance Code - Public Companies” within seven months from the closing date of each fiscal year.  Notwithstanding, since the governance practices set forth in the Governance Code are imposed only on a “comply or explain” basis, adherence to the recommendations described therein is not mandatory, however an explanation must be disclosure with respect to any recommendations set forth therein that we do not adopt.

In addition, we have a Nominations, Compensation and Corporate Governance Committee that establishes our corporate governance guidelines, which we disclose to the public on an annual basis.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheet of Telefônica Brasil S.A. and its subsidiaries as of December 31, 2017 (“Company”), and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for the year ended December 31, 2017, including the related notes (collectively referred to as the “consolidated financial statements”).  We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established inInternal Control - Integrated Framework(2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017, and the results of their operations and their cash flows for the year ended December 31, 2017 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.  Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013)issued by the COSO. 

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in Item 15 - Controls and Procedures -  Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits.  We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. 

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.  Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.  Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in the circumstances.  We believe that our audits provide a reasonable basis for our opinions.

F-2

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) 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.

c) Relevant events occurred in 2017 and 2016

c.1) Acquisition of Terra Networks by Wholly-Owned Subsidiary

On July 3, 2017, the Company informed that its wholly-owned subsidiary Telefônica Data S.A. ("TData") has acquired all the shares representing the capital stock of Terra Networks Brasil S.A. ("Terra Networks"), owned by SP Telecomunicações Participações Ltda. ("SPTE"), one of the controlling shareholders of the Company ("Transaction").

Terra Networks is a provider of digital services (own and third-party value-added services ("VAS") and carrier billing, as well as mobile channels for sales and relationships) and advertising.

TData is a company dedicated to the exploration of VAS, as well as integrated business solutions in telecommunications, technical assistance of telecommunications equipment and networks, maintenance of equipment and networks and development of projects.

The total price paid for the acquisition of shares issued by Terra Networks was  R$ 250,000, in a single installment, with no need for any financing, using only the cash available of TData. Such value was calculated based on the economic value of the Terra Networks, according to the discounted cash flow criterion, with a base date of April 30, 2017, based on an appraisal report contracted by TData Board of Directors.

F-12

The Transaction was subject to conditions usually applicable to this type of deal, and was preceded by a legal and financial audit in relation to Terra Networks and valuation by an independent company.

The Transaction was not subject to obtaining any regulatory authorizations or approvals by the Company's regulators and the way it was structured does not change the Company's shareholding structure or cause any dilution to its shareholders, generating value to them through accelerated growth of digital services and increased operational efficiency, there are no significant costs related to the Transaction.

The purpose of the Transaction was to expand and integrate the commercial offer of digital services that can add immediate value to the customer base of TData and of the Company, as well as generating TData service offers to Terra Networks' customer base and subscribers and, thanks to the national presence of Terra Networks' operation and expertise, generate leverage for TData advertising business. In addition, since the Company has the skills to create new digital media products for mobile and advertising and Terra Networks has know-how in selling, attending and operating digital services for specific customers, the acquisition by TData will also facilitate the synergy between the companies involved, in addition to maximize the unification of the commercial conditions maintained with suppliers.

Accounting Method

Considering that business combinations between entities under common control have not yet been specifically addressed by International Financial Reporting Standards (IFRS), an entity is required to apply the hierarchy in paragraphs 10-12 of IAS 8 - Accounting Policies, Change of Estimates and Error Correction to choose the accounting policy to be adopted.

An entity may therefore choose to account for combinations of entities under common control using the Acquisition Method based on IFRS 3 (R) or the carrying amount of the net assets acquired ("Pooling of Interests" or "Predecessor Value Method"), with the guidance provided by other accounting standard-setting bodies with a Conceptual Framework similar to IFRSs.

This Transaction, which as previously described, involves companies under common control, was accounted for at the book value of the net assets acquired (“Predecessor Value Method”), as certain requirements for the use of the acquisition method set forth in IFRS 3 (R). Consequently, the difference between the consideration given in exchange for the equity interest obtained and the value of the net assets acquired was recorded in TData's equity.

Upon completion of the Transaction, as from July 3, 2017, Terra Networks became a direct subsidiary of TData and indirectly owned by the Company.

We present below the composition of the book value of identifiable net assets acquired in the amount of R$190,971.

Provision for Probable Risks and Contingent Liabilities

The agreement for the sale and purchase of this Transaction contains terms and provisions common to this type of transaction, including indemnification of certain liabilities, contingent or materialized, arising from acts or facts occurring up to the date of the Transaction, reducing the amounts already provisioned for the respective contingencies, which were considered in the purchase price.

At the date of the Transaction, Terra Networks was involved in administrative and judicial proceedings related to tax, civil and labor matters, whose unfavorable outcomes are considered probable and possible, as the case may be.

Other information

The net book value of trade accounts receivable provided by Terra Networks totals R$61,276, which does not differ from the gross amount of R$69,995, net of estimated losses for impairment of R$8,719.

From the date of acquisition until the conclusion of the financial statements for the period ended December 31, 2017, Terra Networks contributed R$155,224 of consolidated net operating revenue and R$179,615 of consolidated net income to the Company, mainly due to the recognition of R$125,191 of income tax on tax losses and negative basis of social contribution (note 7 b).

c.2) Corporate restructuring - 2016

The Shareholders’ Meeting held on April 1, 2016, approved corporate restructuring in accordance with the terms and conditions proposed on March 14, 2016.

The corporate restructuring was approved by ANATEL through Ruling No. 50,169, dated January 22, 2016, which was published in the DOU on January 28, 2016, with the conditions provided therein.

GVT Participações S.A. (“GVTPart.”) was the parent company of Global Village Telecom S.A. ("GVT"), companies controlled by the Company from May 28, 2015 to April 1, 2016. GVT was the direct controlling holder of POP Internet Ltda. (“POP”), and indirect controlling holder of Innoweb Ltda. (“Innoweb”), both with head offices in Brazil.

F-14

POP is a provider of free Internet access and content. Innoweb (subsidiary of POP) provides services using VoIP technology (voicer over IP), which allows calls using the Internet, with the facilities inherent in this environment.

The corporate restructuring occurred on the same date as the Shareholders’ Meeting mentioned above, as follows: (i) GVT was spun-off and its net assets, including assets, rights and obligations related to telecommunications activities, were absorbed by GVTPart., where as the remaining portion relating to assets, rights and obligations related to activities other than telecommunications was absorbed by POP; and (ii) the net assets of GVTPart. (after the merger of GVT’s net assets, item (i)) was merged into the Company.

The corporate restructuring intends to standardize the services provided by the companies involved in this process by (i) concentrating the rendering of telecommunication services in a single company, i.e., the Company; and (ii) migrating of activities that were provided by GVT, other than telecommunication services to POP.

As such, the simplification of the corporate structure and the centralization of the provision of telecommunication services at the Company will lead to a converging environment, facilitating consolidation and centralization in the offering of telecommunication services and simplification of service package offerings; optimizing administrative and operating costs; and standardization of the operations at the companies involved in the corporate restructuring.

Given that the merger of GVTPart. into the Company did not require a capital increase or a change in shareholders’ interest in the Company, since GVTPart. was a wholly-owned subsidiary of the Company, the replacement of shares held by the shareholders in GVTPart. with shares in the Company is not applicable. Consequently, there are no minority interests to be considered and, therefore, in accordance with the CVM’s position in similar prior cases, and under the terms of CVM Resolution No. 559/08, the provisions of article 264 of Law No. 6404/76 and its further amendments similarly do not apply.

In addition, in relation to the transaction preceding the merger of GVTPart into the Company, the replacement of shares is not applicable, given that GVT is a subsidiary of GVTPart. and of the Company itself, thus there are no minority shareholders. Pursuant to the provisions of article 137 of Law No. 6404/76 and its further amendments, the corporate restructuring does not entitle the Company’s shareholders to the right of withdrawal. Furthermore, considering that there are no minority shareholders of GVTPart., since it is a wholly-owned subsidiary of the Company, there is no question of right to withdrawal or exercise of the right to withdraw by GVTPart. non-controlling shareholders as provided for in article 136, item iv, and article 137 of Law No. 6404/76 and its further amendments.

c.3 Acquisition of GVT Participações S.A. (“GVTPart.”)

Pursuant to, and for the purposes of, CVM Rule No. 358/02, the Company informed the market that its Special Shareholders’ Meeting (“AGE”) held on May 28, 2015 approved the ratification of the Stock Purchase Agreement and Other Covenants executed by the Company, in the capacity of “Buyer”, and Vivendi and its subsidiaries (Société d’Investissements et de Gestion 108 SAS - “FrHolding108” and Société d’Investissements et de Gestion 72 S.A.), in the capacity of “Sellers”, whereby all the shares issued by GVTPart were acquired by the Company.

Payment for acquisition of GVTPart. shares was made as follows: (i) €4.663 billion paid in cash after contractual adjustments for net debt assumed on the execution date; and (ii) Company-issued shares delivered to FRHolding108 as a result of the merger of GVTPart shares by the Company, representing 12% of the Company’s capital stock after the merger of shares.

F-15

As a result of the merger of GVTPart. shares, the Company’s capital increased by R$9,666,021, with the issuance of 68,597,306 common shares and 134,320,885 preferred shares, all registered, no-par value shares, based on the economic value of merged shares calculated using the discounted cash flow method and on the appraisal report on GVTPart’s economic value prepared by an expert firm, in accordance with article 252, paragraph 1, together with article 8, of Law No. 6404/76.  The difference between the economic value of merged shares and the market value of shares issued on the transaction closing date was recognized in “Other Capital Reserves”, in the amount of R$1,188,707.

This transaction was subject to obtaining of applicable corporate and regulatory approvals, including from Brazil’s Administrative Council for Economic Defense (“CADE”) and ANATEL, further to other conditions usually applicable to this type of transaction. The transaction was approved by ANATEL under Act No. 448 of January 22, 2015, published in the Official Federal Gazette (“DOU”) on January 26, 2015, and by CADE at the 61st ordinary session of its Trial Court, held on March 25, 2015, and published in the Official Federal Gazette (“DOU”) on March 31, 2015.

Once the acquisition transaction was completed on May 28, 2015, the Company held direct interest in GVTPart and indirect interest in GVT. GVTPart. is headquartered in Brazil as its business purpose includes participation in other companies, whether national or foreign, as partner, shareholder or member. Its direct subsidiary (GVT) provides landline telephone, data, multimedia communication and pay-tv services throughout Brazilian territory.

Under IFRS 3 (R) – Business Combinations, business acquisitions are accounted for using the acquisition method.  The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the fair value of assets transferred, the liabilities assumed at the acquisition date from the former acquiree’s shareholders and equity interests issued in exchange for control over the acquiree.

The acquisition price was as follows:

Gross consideration in cash (4.663 billion euros)	15,964,853
(-) Contractual Adjustments (Net Debt)	(7,060,899)
Total consideration in cash, net	8,903,954
(+) Contingent Consideration	344,217
(+) Consideration in Shares at Fair Value	8,477,314
(-) Cash Flow Hedge Gain on Transaction, net of taxes (1)	(377,373)
(-) Refund according to sections 2.2.4 and 2.2.5 of SPA	(84,598)
Total consideration, net of Cash Flow Hedge	17,263,514
(1) Derivative transactions refer to cash flow hedges to protect the amount due in Euros to Vivendi, for the acquisition of GVTPart., against exchange rate variation of the amount.

A breakdown of the fair value of identifiable net assets acquired for R$4,426,373, as well as goodwill recorded on the acquisition date are presented below. At the date of preparation of the financial statements for the year ended December 31, 2015, the Company had already completed the revisions and adjustments of the fair value determination of the identifiable assets acquired and liabilities assumed by GVTPart.

(1)This includes the allocation of appreciation of property, plant and equipment items (R$409,601).

(2)This includes the allocation of fair value assigned to the brand (R$59,000), customer portfolio (R$2,523,000), appreciation and other intangibles assets (R$20,394). (3)This includes the allocation of fair value assigned to contingent liabilities (R$512,648). (4)This includes the allocation of deferred taxes on contingent liabilities (R$174,300). (5)This refers to goodwill recorded on the acquisition of GVTPart. based on expected synergies resulting from the business combination. This amount has already been used for tax purposes.

The main purpose of the Company’s acquiring of control over GVTPart was to enable the integration of landline, mobile, data and TV telecommunication services in Brazil, with a view to operating more efficiently. The acquisition of GVTPart. allows the Company to obtain significant synergies in revenues and costs, thus generating opportunities of cross sales in the individual and corporate markets, also allowing optimization of investments, improvement of service quality, reduction of cost of content, acquisition and platform in the pay-tv business, due to economies of scale, as well as reduction of general and administrative expenses, not affecting the Company’s growth potential.

The methods and assumptions used to determine the fair values were:

Customer portfolio

The customer portfolio was valued using the MEEM method (“Multi-period Excess Earnings Method”), which is based on a discounted cash flow calculation of future economic benefits attributable to the customer base, net of eliminated liabilities for contributions involving its generation.

In order to estimate the remaining useful life of the customer portfolio, an analysis of the average length of customer relationships was conducted using a churn method. 

The purpose of the useful life analysis is to estimate a survival curve that anticipates future churn rates in relation to the existing customer base. The so-called Iowa curves were used as an approximation to the customer survival curve. The fair value allocated to the customer portfolio on the acquisition date was R$2,523,000, which will be amortized over 7.77 years on average.

F-17

Brand

The fair value of “GVT” brand was determined through the "relief-from-royalty” method. This method measures the value of the asset by capitalizing the royalties saved by owning intellectual property.  In other words, the owner of the brand profits from owning the intangible asset, rather than having to pay royalties for its use. The royalties saved were determined by applying a market royalty rate (expressed as a percentage of revenue) to the future expected revenues from the sale of the product or service associated with the intangible asset. The market royalty rate, normally expressed as a percentage of net revenue, is the rate a knowledgeable willing owner would charge a knowledgeable willing user for use of an asset it owns in an arm’s length transaction. The fair value allocated to the brand on the acquisition date was R$59,000, which will be amortized over 1.5 years.

Contingent Consideration

As part of the Stock Purchase Agreement and Other Covenants executed by the Company and Vivendi for the acquisition of all GVTPart-issued shares, a contingent consideration was defined for the court deposits made by GVT for the monthly installments of deferred income and social contribution taxes on the amortization of goodwill arising from the corporate restructuring process completed by GVT in 2013. In September 2014, GVT filed for a cancellation of the judicial review and the return of amounts deposited with the courts.

If GVT succeeds in receiving (being reimbursed, refunded or netting) these funds, they will be returned to Vivendi, as long as they are obtained in a final unappeasable decision.  The period for returning such amount is of up to 15 years. The fair value of the contingent consideration on the acquisition date is R$344,217, recorded in the Company’s noncurrent liabilities as “Loans, Financing and Debentures” (Note 20), which is subject to monthly monetary adjustments based on the Selic rate.

Fair value of contingent liabilities

According to IFRS 3 (R) - Business Combinations, the acquirer must recognize, on the acquisition date, contingent liabilities assumed in a business combination, even if it is not probable that cash outflows will be required to settle the obligation, as long as it is a present obligation arising from past events and its fair value can be measured reliably.

In compliance with these requirements, contingent liabilities were recognized the amount of R$512,648 of contingent liabilities at fair value, which were determined considering the expected cash outflow required to settle the obligation on the acquisition date. 

2)    BASIS OF PREPARATION AND PRESENTATION OF FINANCIAL STATEMENTS a) Statement of compliance

The consolidated financial statements were prepared and are presented in accordance with the International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB).

b) Basis of preparation and presentation

The Company’s financial statements for the years ended December 31, 2017, 2016 and 2015 are presented in thousands of reais (unless otherwise stated), which is the Company’s functional currency and were prepared under the going concern assumption.

The Board of Directors authorized the issue of these consolidated financial statements at the meeting held on February 16, 2018.

F-18

The financial statements were prepared on a historical cost basis (except where different criteria are required) and adjusted to reflect the valuation of assets and liabilities measured at fair value or considering the mark-to-market valuation when such valuations are required by IFRS.

These financial statements were prepared under various measurement bases used in accounting estimates. The accounting estimates involved in the preparation of these financial statements were based on objective and subjective factors, considering management’s judgment for determining the adequate amounts to be recorded in the financial statements. Significant items subject to these estimates and assumptions include: selection of useful lives and recoverability of property, plant and equipment in operations, measurement of the recoverability of assets with indefinite useful lives, measurement of financial assets at fair value and under present value adjustment method, as well as non-financial assets acquired in a business combination, credit risk analysis in determining estimated impairment losses of trade accounts receivable, as well as the analysis of other risks in determining other provisions, including the provision for contingencies. The carrying amounts of assets and liabilities recognized, which represent hedged items at fair value, which, alternatively, would have been recorded at amortized cost, are adjusted to state the variations in fair values attributable to the hedged risks.

Settlement of transactions involving these estimates may result in amounts significantly different from those recorded in the financial statements due to the uncertainties inherent in their estimate process. The Company reviews its estimates at least on an annual basis.

For comparability of the consolidated financial statements (income statement, statements of comprehensive income, statements of value added and statements of cash flows) for years ended December 31, 2017, 2016 and 2015, the effects of acquisition of Terra Networks by TData occurred on July 3, 2017 (note 1.c.1).

The accounting policies adopted in the preparation of the consolidated financial statements for the year ended December 31, 2017 are consistent with those used in the preparation of the consolidated annual financial statements for the year ended December 31, 2016. The following amendments to standards published by the International Accounting Standards Board (IASB) come into force for annual periods beginning on or after January 1, 2017:

·Improvements to IFRS 2014-2016: The annual improvements projects provide a vehicle for making non-urgent but necessary amendments to IFRS, with the aim of removing inconsistencies and clarifying wording. The amendments related to IFRS 12 Disclosure of Interests in other Entities, aimed clarifying the scope of the standard, come into force for annual periods beginning on or after January 1, 2017, whereas the rest of the improvements come into force for annual periods beginning on or after January 1, 2018. The amendments related to IFRS 12 do not have an impact on the Company’s consolidated financial statements since, as of December 31, 2017, the Company does not have participations that are classified as held for sale, as held for distribution or as discontinued operations.

·Amendments to IAS 7, Disclosure Initiative: The amendments to IAS 7 require entities to provide disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flows, such as the issue and repayments of loans, and non-cash changes, such as unpaid acquisitions, sales and exchange differences.

·Amendments to IAS 12, Recognition of Deferred Tax Assets for Unrealised Losses: The amendments clarify the requirements on recognition of deferred taxes when the tax base of an asset exceeds its fair value.

The Company considered these amendments in the preparation of the annual consolidated financial statements; however, did not generate a significant impact on its results or financial position.

On the date of preparation of these financial statements, the following IFRS amendments had been published; however, their application was not mandatory. The Company does not adopt early any pronouncement, interpretation or amendment that has been issued, before application is mandatory.

Based on the analyses made to date, the Company estimates that the adoption of many of these standards, amendments and interpretations will not have a significant impact on the consolidated financial statements in the initial period of adoption. However, for the following issued but not yet effective standards are expected to have a significant impact on the consolidated financial statements at the time of their adoption and prospectively.

IFRS 15 Revenues from Contracts with Customers

IFRS 15 sets out the requirements for recognising revenue from contracts with customers. The new requirements are expected to affect the following aspects, among others:

Under IFRS 15, for bundled packages that combine multiple wireline, wireless, data, internet or television goods or services, the total revenue will be allocated to each performance obligation based on their standalone selling prices in relation to the total consideration of the package and will be recognized when (or as) the obligation is satisfied, regardless of whether there are undelivered items. This differs from current accounting where the portion of the total consideration that is contingent upon delivery of undelivered elements is not allocated to the delivered elements. Consequently, when bundles include a discount on equipment, the adoption of these new requirements will result in an increase in revenues recognized from the sale of handsets and other equipment, generally recognized upon delivery to the end customer, in detriment of ongoing service revenue over subsequent periods. To the extent that the packages are marketed at a discount, the difference between the revenue from the sale of equipment and the consideration received from the customer upfront will be recognized as a contract asset on the statement of financial position.

Under the current accounting policy, all expenses directly related with obtaining a contract (sales commissions and other third party acquisition costs) are expensed when incurred. However, IFRS 15 requires the recognition of an asset for those costs that are incremental to obtain a contract and that are expected to be recovered and its subsequent amortisation over the same period as the revenue associated with such asset. Similarly, certain contract fulfilment costs, which are currently expensed when incurred, will be deferred under IFRS 15 to the extent that they relate to performance obligations that are satisfied over time.

F-20

The guidance in IFRS 15 for the distinction between agent and principal is based on the concept of “control” that may differ from the currently applied notion of transfer of “risks and rewards”. As a result, with the adoption of IFRS 15, the Company will record revenue from the sale of handsets to dealers at the time of delivery and not at the time of sale to the final customer.

Compared to the current revenue standard, IFRS 15 sets out more detailed requirements on how to account for contract modifications. Certain changes must be accounted for as a retrospective change (i.e. as a continuation of the original contract), while other modifications must be accounted for prospectively as separate contracts, like the end of the original contract and the creation of a new one.

In addition to this, IFRS 15 allows for two transition methods, namely the full retrospective method and the modified retrospective method with the cumulative effect from initial application recognized as an adjustment to the opening balance of retained earnings at the date of initial application. The Company will adopt the latter and prior-year comparatives will not be restated; instead, the Company will disclose the nature and amount of the changes in items in the statement of financial position and the income statement as a result of applying IFRS 15 for the first time.

It is also possible to elect to apply certain practical expedients to facilitate the application of the new criteria. The Company has evaluated which of them will be adopted in the implementation of the standard with the objective of reducing the complexity in its application. The main practical expedients that the Company will adopt are:

· Completed contracts: the Company will not apply the standard retrospectively to those contracts that are completed at January 1, 2018.

· Portfolio approach: the Company will apply the requirements of the standard to groups of contracts with similar characteristics, since, for the clusters identified, the effects do not differ significantly from an application on a contract by contract basis.

· Financial component: it will not be considered significant when the period between the moment when the promised good or service is transferred to a customer and the moment when the customer pays for that good or service is one year or less.

· Costs to obtain a contract: these costs will be recognized as an expense when incurred if the amortisation period of the asset that the entity would otherwise recognise is one year or less.

The process of implementing the new requirements involves the introduction of modifications to the current information systems, the implementation of new IT tools, and changes in the processes and controls of the entire revenue cycle in the Company. This process of implementation in the Company entails a high degree of complexity due to factors such as a large number of contracts, numerous data source systems, as well as the need to make complex estimates.

From the analysis performed on the transactions of the last financial year considering commercial offers as well as the volume of contracts affected, the Company estimates that the adoption of the new revenue recognition requirements on its equity is expected to result in an increase in retained earnings of 156 million reais before deferred taxes, being the most significant impacts due to the changes introduced by IFRS 15 relating to the first-time recognition of contract assets that, under IFRS 15, lead to the earlier recognition of revenue from the sale of goods, and the activation and deferral of the incremental costs related to the obtaining contracts and contract fulfilment costs that, under IFRS 15, result in the later recognition of customer acquisition costs and other selling expenses.

As the accounting effects of the transition to the new standard will be recognized directly in equity, the effects on profit or loss in 2018 will be related to changes in the point in time at which revenue and expenses are realized. The Company expects a shift from revenues from the provision of services to revenues from the sale of goods, by between 0.3 and 0.7 percentage point on the assumption that there are no significant changes to business models or products offered.

F-21

IFRS 9 Financial Instruments

IFRS 9 is applicable to financial assets and financial liabilities. As a result of the analysis of the effects of the new requirements introduced by this standard certain expected impacts have been identified in relation with the following aspects, among others:

·IFRS 9 simplifies the current measurement model for financial assets and establishes three main categories: amortised cost, fair value through profit or loss and fair value through Other Comprehensive Income (OCI), depending on the business model and the characteristics of the contractual cash flows. Regarding recognition and measurement of financial liabilities there are not significant changes from current criteria except for the recognition of changes in own credit risk in OCI for those liabilities designated at fair value through profit or loss.

·IFRS 9 introduces a new model for impairment losses on financial assets, i.e. the expected credit loss model, which replaces the current incurred loss model. The Company will apply the simplified approach and record lifetime expected losses on all trade receivables. Consequently, the application of the new requirements will probably lead to an acceleration in the recognition of impairment losses on its financial assets, mainly trade receivables.

·Under current accounting, a hedge must be highly effective both, prospective and retrospectively, while IFRS 9 introduces a new, less restrictive, accounting model for hedging, requiring an economic relationship between the hedged item and the hedging instrument and that the coverage ratio be the same as that applied by the entity for its risk management. Likewise, the new standard modifies the criteria for documentation of hedging relationships.

·In addition to this, the Company's financial statements will include more detailed disclosures with relevant information regarding financial assets and liabilities.

As a result of the analysis of the new standard, the Company expects that the key changes will relate to documentation of policies and hedging strategies, as well as the estimation and timing of recognition of expected losses on receivables from customers. The Company has decided to apply the option that allows not to restate comparative periods to be presented in the year of initial application.

Based on the analysis performed to date, the Company estimates that the new impairment requirements is expected to result upon initial adoption in a decrease of 354 million reais in retained earnings, before deferred taxes, as a result of the increase in the bad debt provision balance on receivables from customers recognized under IAS 39.

IFRS 16 Leases

IFRS 16 requires lessees to recognise assets and liabilities arising from all leases (except for short-term leases and leases of low-value assets) in the statement of financial position.

The Company acts as a lessee on a very significant number of lease agreements over different assets, such as third-party towers, circuits, office buildings and stores and land where the towers are located, mainly. A significant portion of these contracts is accounted for as operating lease under the current lease standard, with lease payments being recognized generally on a straight-line basis over the contract term.

The Company is currently in the process of estimating the impact of this new standard on such contracts. This analysis includes the estimation of the lease term, based on the non-cancellable period and the periods covered by options to extend the lease, when the exercise depends only on Telefônica and where such exercise is reasonably certain. This will depend, to a large extent, on the specific facts and circumstances by class of assets in the telecom industry (technology, regulation, competition, business model, among others).  In addition to this, the Company will make assumptions to calculate the discount rate, which will mainly be based on the incremental borrowing rate of interest for the estimated term. On the other hand, the Company is considering not to separately recognise non-lease components from lease components for those classes of assets in which non-lease components are not material with respect to the total value of the lease.

F-22

In addition to the mentioned estimations, the standard allows for two transition methods: retrospectively for all periods presented, or using a modified retrospective approach where the cumulative effect of adoption is recognized at the date of initial application. The Company has tentatively decided to adopt the latter transition method; therefore the Company would recognise the cumulative effect of initial application as an adjustment to retained earnings in the year of initial application of IFRS 16. Also, certain practical expedients are available on first-time application in connection with the right of use asset measurement, discount rates, impairment, leases that finish within the twelve months subsequent to the date of first application, initial direct costs, and term of the lease. The Company is evaluating which of these practical expedients will be adopted. In this regard, the Company is considering opting for the practical expedient that allows not reassessing whether a contract is or contains a lease on the date of initial application of IFRS 16 but to directly apply the new requirements to all those contracts which under current accounting were identified as a lease.

Due to the different alternatives available, together with the complexity of the estimations and the significant number of lease contracts, the Company has not yet completed the implementation process, so at present it is not possible to make a reasonable estimation of the impact of initial application of the new requirements. However, based on the volume of contracts affected, as well as the magnitude of the future lease commitments, as disclosed in Note 32 herein, the Company expects that the changes introduced by IFRS 16 will have a significant impact on its financial statements from the date of adoption, including the recognition on the balance sheet of right of use assets and their corresponding lease obligations in connection with the majority of contracts that are classified as operating leases under the current lease standard. Also, amortization of the right of use assets and recognition of interest costs on the lease obligation on the statements of income will replace amounts recognized as lease expense under the current lease standard. Classification of lease payments in the statement of cash flows will also be affected by the requirements of the new lease standard. On the other side, the Company's Financial Statements will include broader disclosures with relevant information regarding lease contracts.

c) Basis of consolidation

The consolidated financial statements include the financial statements of the Company and its subsidiaries at December 31, 2017, 2016 and 2015 (Note 11).

The Company held the following direct equity interests on the respective dates:

Investees
Investees	Type of investment	Equity interests	Country (Headquarters)	Core activity
Telefônica Data S.A. ("TData") (1)	Wholly-owned subsidiary	100.00%	Brazil	Telecommunications
POP Internet Ltda ("POP") (2)	Wholly-owned subsidiary	100.00%	Brazil	Internet
Aliança Atlântica Holding B.V. ("Aliança")	Jointly-controlled subsidiary	50.00%	Holland	Holding of the telecommunications sector
Companhia AIX de Participações ("AIX")	Jointly-controlled subsidiary	50.00%	Brazil	Operation of underground telecommunications networks
Companhia ACT de Participações ("ACT")	Jointly-controlled subsidiary	50.00%	Brazil	Technical assistance in telecommunication networks

(1)	TData is the wholly-owned parent of Terra Networks and Telefônica Transportes e Logística Ltda ("TGLog").
(2)	POP is the wholly-owned parent of Innoweb Ltda ("Innoweb").

Interest held in subsidiaries or jointly-controlled entities is measured under the equity method in the individual financial statements. In the consolidated financial statements, investments and all asset and liability balances, revenues and expenses arising from transactions and interest held in subsidiaries are fully eliminated. Investments in jointly-controlled entities are measured under the equity method in the consolidated financial statements.

F-23

3)   SUMMARY OF SIGNIFICANT ACCOUNTING PRACTICES

a) Cash and cash equivalents

These are maintained in order to meet short-term cash commitments and not for investment or other purposes. The Company consider cash equivalents a short-term investment readily convertible into a known amount of cash and subject to insignificant risk of change in value. Short-term investments are classified as cash-equivalent when redeemable within 90 days (Note 4).

b) Trade accounts receivable

These are evaluated by the value of the services provided in accordance with the contracted conditions, net of estimated impairment losses. These include the services provided to customers, which were still not billed until balance sheet date, as well as other trade accounts receivable related to the sale of cellphones, SIM cards, accessories, advertising and rent of IT equipment (TData’s “Soluciona TI” product), (Note 5).

The estimated impairment losses are set up at amounts sufficient to cover any losses and mainly consider the expected default.

c) Inventories

These are evaluated and presented at lower of average acquisition cost and net realizable value, whichever is lower. These include cellphones, SIM cards, prepaid cards, accessories, consumption materials and maintenance. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs to sell (Note 6).

Estimated impairment losses are set up for materials and devices considered obsolete or whose carrying amounts are in excess of those usually sold by the Company within a reasonable period of time.

d) Prepaid expenses

These are stated at amounts effectively disbursed referring to services contracted but not yet incurred. Prepaid expenses are allocated to the income statements to the extent that related services are rendered and economic benefits are obtained (Note 9). 

e) Investments

Control is obtained when the Company is exposed or has the right to variable returns based on its involvement with the investee and has the capacity of affecting those returns through the power exercised over an investee.

The consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ends when the Company ceases to exercise said control. Assets, liabilities and results of a subsidiary acquired or sold during the year are included in the consolidated financial statements from the date on which the Company obtains control until the date on which the Company ceases to exercise control over the subsidiary.

Joint control is the contractually agreed sharing of a control, only existing when decisions about relevant activities call for unanimous agreement by the parties sharing control.

Based on the equity method, investments are recorded in balance sheets at cost plus changes after the acquisition of the equity interest. The income statement reflects the portion of the results of operations of the investees.

When changes are directly recognized in the investees' equity, the Company will recognize its portion in variations occurred, and as record these variations in the statements of changes in equity and in the statements of comprehensive income, where applicable.

The financial statements of investees are prepared for the same reporting period of the Company. Whenever necessary, adjustments are made so that the accounting policies are in accordance with those adopted by the Company.

F-24

After the equity method is applied, the Company determines whether there is any need to recognize additional impairment of its investment in investees. At each closing date, the Company determines whether there is objective evidence of impairment of investment in the affiliate. If so, the Company calculates the recoverable amount as the difference between the recoverable value of the investees and their carrying amount, and recognizes the amount in the income statements.

When there is loss of significant influence over the investees, the Company evaluates and recognizes the investment, at that moment, at fair value. Any difference between the investees’ carrying amount by the time it loses significant influence and the fair value of the remaining investment and revenue from sale is recognized in the income statements.

Foreign exchange variations in Aliança’s equity (jointly-controlled entity) are recognized in the Company’s equity in other comprehensive income (“Effects on conversion of investments abroad”, Note 22).

f) Property, plant and equipment

Property, plant and equipment are stated at acquisition and/or construction cost, net of accumulated depreciation and/or accumulated impairment losses, if any. Such cost includes the borrowing costs for long-term construction projects if the recognition criteria are met, and is stated net of ICMS (State VAT) credits, which were recorded as recoverable taxes.

Asset costs are capitalized until the asset becomes operational. Costs incurred after the asset becomes operational and that do not improve the functionality or extend the useful life of the asset are immediately recognized on the accrual basis. When significant parts of fixed assets are required to be replaced at intervals, the Company recognizes such parts as individual assets with specific useful lives and depreciation. Likewise, expenses that represent asset improvement (expanded installed capacity or useful life) are capitalized. All the other repair and maintenance costs are recognized in the income statement as incurred.

The present value of the expected cost for the decommissioning of property, plant and equipment items (towers and equipment on leased property) is capitalized at the cost of the respective asset matched against the provision for dismantling obligations (Note 18) and depreciated over the useful lives of the related assets, which do not exceed the lease term.

Depreciation is calculated by the straight-line method over the useful lives of assets at rates that take into account the estimated useful lives of assets based on technical analyses. The assets’ residual values, useful lives and methods of depreciation are reviewed on a yearly basis, adjusted prospectively, if appropriate. Useful life in terms of depreciation rates, which is reviewed annually by the Company.

Property, plant and equipment items are written off when sold or when no future economic benefit is expected from their use or sale. Any gains or losses arising from write-off of assets (measured as the difference between the net disposal proceeds and the net carrying amount of the asset) are recognized in the income statement in the year in which the asset is written off.

A brief description of the main property, plant and equipment items, Note 12 is as follows:

·Switching and transmission media equipment: Includes switching and control centers, gateway, platforms, base radio station, microcells, minicells, repeaters, antennas, radios, access networks, concentrators, cables, TV equipment and other switching and transmission media equipment.

·Terminal/modem equipment: Includes cellphones and modems (rent and free lease), CPCT, public telephones and other terminal equipment.

·Infrastructure: This includes buildings, elevators, central air conditioning equipment, towers, posts, containers, energy equipment, land piping, support and protectors, leasehold improvements, etc.

F-25

·Other fixed asset items: These include vehicles, repair and construction tools and instruments, telesupervision equipment, IT equipment, testing and measurement equipment, fixtures and other goods for general use.

g) Intangible assets

Intangible assets acquired separately are measured at cost upon their initial recognition. The cost of an intangible asset acquired in a business combination is its fair value at the acquisition date.

After initial recognition, intangible assets are stated at acquisition and/or buildup cost, net of amortization and accumulated provision for impairment, where applicable. Intangible assets generated internally, excluding capitalized development costs, are not capitalized, and the expense is reflected in the income statement for the year in which it is incurred.

The useful lives of intangible assets are considered finite or indefinite.

·Intangible assets with finite useful lives are amortized over their economic useful lives under the straight-line method and are tested for impairment whenever there is any indication of impairment loss. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed on an annual basis.

Changes in the estimated useful life or the expected pattern of consumption of future economic benefits embodied in an asset are accounted for by changing the amortization period or method, as appropriate, and treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the income statement in the cost/expense category consistent with the function of the intangible assets.

·Intangible assets with indefinite useful lives are not amortized, but are tested for impairment annually, either individually or at the cash-generating unit level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be justifiable. Otherwise, changes in useful life – from indefinite to finite - are carried out prospectively. Goodwill generated upon investment acquisition is treated as intangible assets with indefinite useful lives.

Gains and losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset, and recognized in the income statement on disposal.

A brief description of the key intangible asset items with finite useful lives, Note 13, is as follows:

·Software: This includes licenses for software used in the Company’s operating, commercial and administrative activities.

·Customer portfolio: This includes intangible assets acquired through business combination, recorded at fair value on the acquisition date.

·Trademarks:  These include intangible assets acquired through business combination, recorded at fair value on the acquisition date.

·Licenses: These include concession and authorization licenses, acquired from ANATEL for provision of telecommunication services. These also include licenses from business combinations, recorded at fair value on the acquisition date.

h) Lease

The classification of an agreement as a lease is based on substantive issues related to the use of an asset or specific assets, or even the right to use a given asset, on the initial date of its execution.

F-26

Finance lease agreements: By means of these agreements, the Company assumes substantially all risks and rewards relating to ownership of a leased item. These are capitalized at the lease inception at the fair value of the leased asset or, if lower, at the present value of the minimum lease payments. Initial direct costs incurred in the transaction are added to cost, where applicable. Payments of finance lease agreements are allocated to financial charges and reduction of finance lease liabilities in order to obtain the constant interest rate on the outstanding liability balance. Implicit interest recognized in liabilities is allocated to the income statement over the lease term using the effective interest rate method.

Leased assets are depreciated according to their estimated useful lives or the lease term, whichever is shorter.

The Company and TData are parties to the following finance lease agreements:

·As lessee: lease agreements for transmission equipment and media arising from a joint construction agreement with another telecomm operator, based on an optical network linked to the power transmission line, interconnecting the northern Brazilian cities to the Company’s national backbone and lease of towers and rooftops (arising from sale and finance leaseback, for which the net carrying amount of the assets upon disposal remained unchanged, a liability was recognized at the present value of minimum lease payments and deferred income was recorded at the difference between the selling price and the mentioned present value. (Note 19).

·As lessor: Lease agreements for IT equipment (TData’s “Soluciona TI” product) for which the Company recognizes revenue, upon inception, at the present value of lease payments matched against accounts receivable (Note 5).

The difference between the nominal amount of lease payments and recorded accounts receivable/payable are recognized as finance income/expenses using the effective interest method over the lease term.

Operating lease: These are lease agreements where lessor holds a significant portion of risks and rewards, where effects are recognized in the income statements for the year over the contractual term.

i) Impairment of nonfinancial assets

The Company annually reviews the net carrying amount of assets in order to evaluate events or changes in economic, operating or technological circumstances that may indicate impairmentlosses. When such evidence is found, and net carrying amount exceeds recoverable amount, a provision for impairment is recorded so as to adjust the net carrying amount to the recoverable amount.

The recoverable amount of an asset or a Cash Generating Unit (“CGU”) is defined as the higher of value in use and net sales value.

Upon estimation of the value in use of an asset or cash-generating unit, estimated future cash flows are discounted at present value using a discount rate based on the cost of capital rate the Capital Asset Pricing Model (CAPM) before taxes, which reflects the weighted average cost of capital and specific risks of the asset or CGU.

Whenever possible, the net sale value is determined based on a firm sale agreement executed on an arm’s length basis between knowledgeable and willing parties, adjusted by expenses attributable to the sale of assets or, when there is no firm sale agreement, based on the market price of an active market, or on the latest transaction price involving similar assets.

For assets excluding goodwill, an assessment is made at each reporting date as to whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased.

A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine an asset’s or CGU recoverable amount since the last impairment loss was recognized. Any reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, or exceeds the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the income statement.

F-27

The following assets have specific characteristics for impairment testing:

·Goodwill: Goodwill is tested for impairment annually at the reporting date or before when circumstances indicate that the carrying amount may be impaired. Where the recoverable amount is lower than the carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods.

·Intangible assets: Intangible assets with indefinite useful lives are tested for impairment annually at the reporting date either individually or at the CGU level, as appropriate, and when circumstances indicate that the carrying amount may be impaired.

·Determination of value in use: The key assumptions used to estimate value in use are: (i) revenues (projected considering the growth in customer base, growth in market revenue against GDP and the Company’s share of this market); (ii) variable costs and expenses (projected in accordance with the dynamics of the customer base, and fixed costs are projected in line with the historical performance of the Company, as well as with revenue growth); and (iii) capital investments (estimated considering the technological infrastructure necessary to enable the provision of services).

Key assumptions were based on the Company’s historical performance and reasonable macroeconomic assumptions grounded on financial market projections, documented and approved by Company’s management.

The impairment test of the Company fixed and intangible assets, including goodwill, did not result in recognition of impairment losses for the years ended December 31, 2017 and 2016, since their estimated recoverable amount is greater than the net carrying amount as of the estimation date.

j) Business combinations and goodwill

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, recorded at fair value on the acquisition date, and the fair value of any noncontrolling interest in the acquiree.

For each business combination, the Company measures noncontrolling interests in the acquiree either at its fair value or on the basis of its proportional share in the identifiable net assets of the acquiree. Costs directly attributable to an acquisition are recorded as expenses, as incurred.

Upon acquiring a business, the Company assesses financial assets acquired and liabilities assumed so as to classify and allocate them in accordance with contractual terms, economic circumstances and relevant conditions on the acquisition date, including the segregation, by the acquiree, of embedded derivatives existing in host contracts in the acquiree.

In the event a business combination is conducted in stages, the ownership interest previously held in the acquiree’s capital is reassessed at fair value on the date control is acquired, and any impacts are recognized in the income statement.

Any contingent portion to be transferred by the acquirer shall be recognized at fair value on the acquisition date. Subsequent changes in the fair value of the contingent portion to be considered as an asset or liability is recognized in the income statement. Contingent consideration on acquisition of a business that is not classified as equity is subsequently measured at fair value through profit or loss, whether or not included in the scope of IFRS 9 Financial Instruments.

Goodwill is initially measured as excess transferred payment amount in relation to acquired net assets (identifiable net assets acquired and liabilities assumed). If consideration is lower than fair value of acquired net assets, the difference must be recognized as gain in the income statement.

F-28

After initial recognition, goodwill is measured at cost, less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to the cash-generating units that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units.

Where goodwill has been allocated to a CGU and part of the operation within that CGU is disposed of, the goodwill associated with that operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed in these circumstances is allocated based on the relative fair values of the disposed operation and the portion of the CGU retained.

k) Financial Instruments – Initial recognition and subsequent measurement

k.1) Financial assets

Initial recognition and measurement

Financial assets are classified at initial recognition (when it becomes part of the instrument's contractual provisions), as: (i) fair value through profit or loss; (ii) loans and receivables; (iii) investments held to maturity; (iv) financial assets available for sale or (v) derivatives classified as effective hedge instruments, as applicable.

All financial assets are initially recognized at fair value, plus, in the case of investment that is not determined at fair value through profit or loss, the transaction costs that are directly attributable to the acquisition of the financial asset.

The Company’s consolidated financial assets include cash and cash equivalents, trade accounts receivable, short-term investments pledged as collateral and derivative financial instruments.

Subsequent measurement

Subsequent measurement of financial assets depends on their classification, as follows:

Financial assets at fair value through profit or loss: These include financial assets held for trading and financial assets designated upon initial recognition at fair value through profit or loss: (i) financial assets are classified as held for trading if acquired to be sold within short term. This category includes derivative financial instruments contracted by the Company which do not meet the hedge accounting criteria set out by the corresponding standard; and (ii) financial assets at fair value through profit or loss are stated in balance sheets at fair value with their corresponding gains or losses recognized in the income statements.

Loans and receivables:  these refer to non-derivative financial assets with fixed or determinable payments, however not traded in an active market.  After initial measurement, these financial assets are stated at amortized cost, using the effective interest method, less impairment, where applicable. Amortized cost is calculated taking into account any discount or “premium” on acquisition and fees or costs incurred. Amortization by the effective interest method and impairment losses are included in the financial income line in the income statement, if applicable.

Financial assets available for sale: These are non-derivative financial assets not classified as: (i) loans and receivables; (ii) investments held to maturity; or (iii) financial assets at fair value through profit or loss. These financial assets include equity and debt instruments. Debt instruments in this category are those which are intended to be held for an indefinite period and can be sold to meet liquidity needs or in response to changes in market conditions.

After initial measurement, financial assets available for sale are measured at fair value, with unrealized gains and losses being recognized directly in other comprehensive income until such time as the investment is written off, except for impairment losses, interest calculated using the effective interest method and gains or losses due to exchange variations on monetary assets, which are recognized directly in the income statement for the year.

F-29

When the investment is written-off or when a loss is determined due to impairment, the cumulative gains or losses which were previously recognized in other comprehensive income should be recognized in the statement of income.

The fair value of financial assets available for sale denominated in foreign currency is measured in the foreign currency and translated at the spot exchange rate at financial statements date. Changes in fair value attributable to translation differences that result from a change in amortized cost of the asset are recognized in the income statement, and other variations are recognized directly in equity.

Derecognition

A financial asset (or, whenever the case, a part of a financial asset, or a part of a group of similar financial assets) is derecognized when:

·The rights to receive the cash flows from the asset have expired;

·The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and either (i) the Company has transferred substantially all the risks and rewards of the asset, or (ii) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

k.2) Impairment of financial assets

The Company evaluate, at the balance sheet date, if there is any objective evidence indicating that the financial asset or group of financial assets is not recoverable. A loss only exists if, and only if, there is objective evidence of impairment as a result of one or more events that have occurred after initial recognition of the asset (a “loss event” occurred) and such event has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reasonably estimated.

The carrying amount of an asset is reduced by a provision and the loss amount is recognized in the income statement. If, in a subsequent year, estimated impairment increases or decreases due to an event after impairment recognition, impairment loss previously recognized will be adjusted accordingly. Should a written-off asset be recovered in the future, such recovery is recognized in the income statement.

k.3) Financial liabilities

Initial recognition and measurement

Upon initial recognition, the Company’s financial liabilities are classified in the following categories:   financial liabilities measured at fair value through profit or loss and other financial liabilities.

Financial liabilities are initially recognized at fair value plus, in the case of loans and financing, transaction cost directly attributable thereto.

The Company’s consolidated financial liabilities include trade accounts payable, loans and financing, debentures, finance lease agreements, contingent payments and derivative financial instruments.

Subsequent measurement

Measurement of financial liabilities depends on their classification, as follows:

F-30

Financial liabilities at fair value through profit or loss: These include financial liabilities designated upon initial recognition at fair value through profit or loss. This category also includes derivative financial instruments contracted which do not meet the hedge accounting criteria set out by the corresponding standard.

For the years ended December 31, 2017 and 2016, the Company did not record any financial liability at fair value through profit or loss upon initial recognition.

Loans and financing: After initial recognition, loans and financing subject to interest are subsequently measured at amortized cost, using the effective interest method. Gains and losses are recognized in the income statement when the liabilities are derecognized as well as through the effective interest rate amortization process.

Derecognition

A financial liability is derecognized when the obligation has been revoked, cancelled or has expired.

When an existing financial liability is replaced by another of the same lender, and the terms of the instruments are substantially different, or when the terms of an existing debt instrument are substantially modified, this replacement or modification is treated as derecognition of the original liability and recognition of a new liability, and the difference in the corresponding carrying amounts is recognized in the income statement.

k.4) Fair value measurement

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Fair value measurement is based on the assumption that the transaction to sell the asset or transfer the liability will take place (i) in the principal market for the asset or liability; or (ii) in the absence of a principal market, in the most advantageous market for that asset or liability.

The Company must have access to the principal (or most advantageous) market.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing an asset or liability, assuming that market participants act in their best economic interests.

Fair value measurement of a non-financial asset takes into consideration the capacity of a market participant to generate economic benefits through the best use of the asset, or selling it to another market participant that would also make the best use of the asset.

The Company use adequate valuation techniques in the circumstances and for which there is sufficient data to measure the fair value, maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs.

For assets and liabilities recurrently recognized in the financial statements, the Company determines whether there were transfers between the hierarchy levels, revaluating the classification (based on the lowest level input that is significant to the overall fair value measurement) at the end of each reporting period.

For the purposes of fair value disclosures, the Company determined classes of assets or liabilities based on the nature, characteristics and risks of those assets or liabilities and the fair value hierarchy level, as mentioned above.

F-31

k.5) Financial instruments - net

Financial assets and liabilities are presented net in the balance sheet if, and only if, there is a current enforceable legal right to offset the amounts recognized and if there is an intention to offset or realize the asset or settle the liability simultaneously.

l) Derivative financial instruments and hedge accounting

The Company uses derivative financial instruments, such as currency and interest rate swaps or currency nondeliverable forward contracts to hedge against currency risks.

Derivative financial instruments designated in hedge transactions are initially recognized at fair value on the date on which the derivative contract is entered into, and subsequently revalued also at fair value. Derivatives are presented as financial assets when the fair value of the instrument is positive and as financial liabilities when the fair value of the instrument is negative.

Any gains or losses resulting from changes in fair value of derivatives during the year are posted directly to the income statement, except for the effective portion of cash flow hedges, which is recognized directly in equity as other comprehensive income and subsequently reclassified to P&L when the hedged item affects P&L.

Inception initial recognition of a hedge relationship, the Company formally designate and documents the hedge relationship to which it wishes to apply hedge accounting, the risk management objective and strategy for undertaking the hedge.

The documentation includes identification of the hedging instrument, the hedged item or transaction, the nature of the hedged risk, the nature of unhedged risks, the prospective statement of hedge effectiveness and how the Company shall assess the effectiveness of changes in the hedging instrument’s fair value in offsetting the exposure to changes in the hedged item’s fair value or cash flows attributable to the hedged risk.

For the purpose of hedge accounting, hedges are classified as cash flow hedges and fair value hedges.

l.1) Cash flow hedges

Cash flow hedges meeting the recording criteria are accounted for as follows: (i) the portion of gain or loss from the hedge instrument determined as effective hedge shall be recognized directly in equity (other comprehensive income), and (ii) the ineffective portion of gain or loss from the hedge instrument shall be recognized in the income statement.

When the Company’s documented risk management strategy for any given hedge relationship excludes from the hedge effectiveness evaluation any particular component of gain or loss or the corresponding cash flows from the hedge instrument, that gain or loss component is recognized in financial income (expenses).

Amounts recorded in other comprehensive income are immediately transferred to the income statement when the hedged transaction affects P&L. When a hedged item is the cost of a non-financial asset or liability, amounts recorded in equity are transferred at the initial carrying amount of the non-financial assets and liabilities.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the hedge fails to meet the hedge accounting criteria, any cumulative gain or loss previously recognized in other comprehensive income remains separately in equity until the forecast transaction occurs or the firm commitment is fulfilled.

The Company's contracts are classified as cash flow hedges when they provide protection against changes in cash flows that are attributable to a particular risk associated with a recognized liability that may affect the profit or loss and fair value when they provide protection against exposure to changes in the fair value of the identified part of certain liabilities that is attributable to a particular risk (exchange variation) and may affect the profit or loss.

F-32

l.2) Fair value hedges 

Fair value hedges meeting the accounting criteria are accounted for as follows: (i) gain or loss from changes in fair value of a hedge instrument shall be recognized in the income statement as finance costs; and (ii) gain or loss from a hedged item attributable to the hedged risk shall adjust the recorded amount of the hedged item to be recognized in the income statement, as finance costs.

For fair value hedges relating to items carried at amortized cost, any adjustment to carrying amount is amortized through profit or loss over the remaining term of the hedge using the effective interest method.  The effective interest rate amortization may begin as soon as any adjustment exists and no later than the point that the hedged item ceases to be adjusted for changes in its fair value attributable to the risk being hedged.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in the income statement.

When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in profit and loss.

l.3) Classification between current and noncurrent 

Derivative financial instruments are classified as current and noncurrent or segregated into short and long term portions based on an evaluation of the contractual cash flows. 

When the Company maintains a derivative as economic hedge (and does not apply hedge accounting), for a period exceeding 12 months after balance sheet date, the derivative is classified as noncurrent (or segregated into current and noncurrent portions), in line with the classification of the corresponding item.

Derivative instruments that are designated as effective hedging instruments are classified consistently with the classification of the underlying hedged item.

The derivative instrument is segregated into current and noncurrent portions only when amounts can be reliably allocated. 

m) Loans and financing

Loans and financing obtained are initially recognized at fair value, net of costs incurred to obtain them and subsequently measured at amortized cost (plus charges and pro rata interest), considering the effective interest rate of each operation.

These are classified as current, unless the Company has an unconditional right to settle the liability for at least 12 months after year end.

n) Borrowing costs

Borrowing costs that are directly attributable to the acquisition, construction or production of an asset that necessarily takes a period of time exceeding 18 months to prepare for its intended use or sale form part of the cost of that asset.

All other borrowing costs are recorded in the period they are incurred. Borrowing costs include interest and other costs incurred by an entity in connection with the borrowing of funds.

F-33

In 2017 and 2016, the Company did not capitalize amounts related to borrowing costs.

o) Interest on equity and dividends

o.1) Interest on equity

Brazilian legislation allows companies to pay interest on equity, which is similar to payment of dividends; however, this is deductible for income tax calculation purposes. In order to comply with Brazilian tax legislation the Company provision, in its accounting records the amount due to match against the financial expenses account in the income statement for the year. For the presentation of these financial statements, that expense is reversed against a direct charge to equity, resulting in the same accounting treatment adopted for dividends. The distribution of interest on equity to shareholders is subject to withholding income tax at a 15% rate.

o.2) Dividends

Minimum mandatory dividends are stated in the balance sheet as legal obligations (provisions in current liabilities). Dividends in excess of such minimum amount, not yet approved in the Shareholders’ Meeting, are recorded in equity as proposed additional dividends. After approval at the Shareholders’ meeting, the dividends in excess of minimum mandatory are transferred to current liabilities, and classified as legal obligations.  

p) Provisions

p.1) General

Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, when it is probable that economic benefits are required to settle the obligation and a reliable estimate of the value of the obligation can be made. Provisions are restated at the balance sheet date considering the likely amount of loss and the nature of each contingency.

Provisions for contingencies are presented at their gross amount, less the corresponding judicial deposits, and are classified as provisions for civil, labor, tax and regulatory contingencies.

Judicial deposits are classified as assets given that the conditions required for their net presentation with the provision do not exist.

p.2) Provisions for civil, labor, tax and regulatory legal claims

The Company is party to labor, tax, civil and regulatory administrative and legal proceedings and set up a provision for contingencies whose likelihood of loss was estimated as probable. The assessment of the likelihood of loss includes an analysis of available evidence, the hierarchy of laws, available case law, the latest court decisions law and their relevance in the legal system, as well as the opinion of outside legal counsel. Provisions are reviewed and adjusted considering changes in existing circumstances, such as the applicable statute of limitations, tax audit conclusions, or additional exposures identified based on new matters or court decisions.

p.3) Provision for decommissioning of assets

This refers to costs to be incurred due to returning sites to owners (locations intended for tower and equipment installation on leased property) in the same condition as these were found at the time of execution of the initial lease agreement.

These costs are provisioned at the present value of amounts expected to settle the obligation using estimated cash flows and are recognized as part of the cost of the corresponding asset. The cash flows are discounted at a current pre-tax rate that reflects the risks specific to decommissioning of assets. The financial effect of the discount is recorded as incurred and recognized in the income statement as a finance cost. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate. Changes in the estimated future costs or in the discount rate applied are added to, or deducted from, the cost of the asset.

F-34

p.4) Contingent liabilities recognized in a business combination

A contingent liability recognized in business combination is initially measured at fair value.

q) Taxes

q.1) Current taxes

Current tax assets and liabilities for the current and prior years are measured at the estimated amount recoverable from, or payable to, the tax authorities. The tax rates and laws used in calculating the amounts referred to above are those in effect, or substantially in effect, at year end. In the balance sheet, current taxes are presented net of prepayments over the year.

Current income and social contribution taxes related to items directly recognized in equity are also recognized in equity. Management regularly assesses the tax position in circumstances in which tax regulation requires interpretation, and sets up provisions therefor when appropriate.

q.2) Deferred taxes

Deferred taxes arise from temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amount.

Deferred tax assets are recognized for all deductible temporary differences, unused tax credits and losses, to the extent that taxable profit is likely to be available for realization of deductible temporary differences, and unused tax credits and losses are likely to be used, except: (i) when the deferred tax asset related to the deductible temporary difference arises from initial recognition of an asset or liability in a transaction other than a business combination and does not impact, at the transaction date, the book profit, income or loss for tax purposes; and (ii) on deductible temporary differences related to investments in subsidiaries, where deferred tax assets are recognized only to the extent that it is probable that temporary differences will be reversed in the near future and taxable profit is likely be available so that temporary differences can be used. 

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit shall be available to allow all or part of the deferred tax asset to be used. Derecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax liabilities are recognized on all temporary tax differences, except: (i) when the deferred tax liability arises from initial recognition of goodwill, or an asset or liability in a transaction other than a business combination, and does not affect book profit or taxable profit or tax losses on the transaction date; and (ii) on temporary tax differences related to investments in subsidiaries, in which the temporary difference reversal period can be controlled and temporary differences are not likely to be reversed in the near future.

Deferred tax assets and liabilities are measured at the tax rate expected to be applicable for the year the asset will be realized or the liability will be settled, based on the rates provided in tax legislation and that were published as of year-end.

Deferred tax assets and liabilities are not discounted to present value and are classified in the balance sheet as noncurrent, irrespective of their expected realization.

F-35

The tax effects of items recorded directly in equity are also recognized in equity. Deferred tax items are recognized based on the transaction which gave rise to that deferred tax, in comprehensive income or directly in equity.

Deferred tax assets and liabilities are presented net when there is a legal or constructive right to offset a tax asset against a tax liability and deferred taxes relate to the same taxpaying entity and are subject to the same tax authority.

q.3) Sales taxes

Revenues are recognized net of value added taxes, which from services rendered is subject to State Value-Added Tax (ICMS) or Service Tax (ISS) at the rates in force in each region as well as and to Social Contribution Tax on Gross Revenue for Social Integration Program (PIS) and Social Contribution Tax on Gross Revenue for Social Security Financing (COFINS) taxation on a cumulative basis for revenue from telecommunication services.

Other revenue earned by the Company, including revenue from resale of goods, on a noncumulative basis, is taxed at for PIS, COFINS and by ICMS at the rates in force in each State.

Prepayments or recoverable amounts are stated in current or noncurrent assets, based on their estimated realization.

r) Other assets and liabilities

Assets are recognized in the balance sheet when it is likely that their future economic benefits will flow to the Company, and their cost or value can be reliably measured.

A liability is recognized in the balance sheet when the Company have a legal or constructive obligation as a result of a past event, the settlement of which is likely to generate an outflow of economic benefits.

Assets and liabilities are presented in the balance sheet classified as current or noncurrent.

An asset is classified as current when: (i) it is expected to be realized or is intended to be sold or used in the ordinary operational cycle; (ii) it is mainly held for trading purposes; (iii) it is expected to be realized within 12 months from the reporting period; or (iv) cash and cash equivalents, unless there are restrictions upon exchange thereof, i.e., when used to settle a liability within 12 months from the reporting period. All other assets are classified as noncurrent.

A liability is classified as current when: (i) it is expected to be settled in the ordinary operational cycle; (ii) it is mainly held for trading purposes; (iii) It is expected to be settled within 12 months from the reporting period; or (iv) there is no unconditional right to defer settlement of the liability within 12 months from the reporting period. All other liabilities are classified as noncurrent.

s) Present value adjustment of assets and liabilities

Current and noncurrent monetary assets and liabilities are adjusted to their present value when the effect on the overall financial statements is considered significant. The present value adjustment is calculated using contractual cash flows and the explicit, and sometimes implicit, interest rates of the respective assets and liabilities.

Accordingly, the interest rate embedded in revenues, expenses and related costs is discounted, so that these assets and liabilities are recognized on an accrual basis. This interest is subsequently reallocated to financial income and expenses in P&L through use of the effective interest method in relation to contractual cash flows. Implicit interest rates were determined based on assumptions, and accounting estimates are considered.

F-36

t) Government grants and assistance

Government grants are recognized when there is reasonable certainty that the benefit will be received and that all the related conditions will be met. When the benefit refers to an expense item, it is recognized as revenue along the benefit period, on a systematic basis in relation to the costs the benefit it intends to offset.

When the Company receives non-monetary grants, the asset and the benefit are recorded at nominal amounts and reflected in the income statements over the expected useful life of the asset by equal annual installments. A loan or assistance is initially recognized or measured at fair value. A government grant is measured as the difference between the initial carrying amount of the loan and proceeds therefrom. A loan is subsequently measured in accordance with the applicable accounting policy.

When loans or similar assistance are provided by governments or related institutions, with an interest rate below the current applicable market rate, the effect of this favorable interest is regarded as an additional government grant.

The financing lines with the Brazilian Development Bank (BNDES), with interest rates not exceeding those prevailing in the market, are classified under the scope of IAS 20, and are recorded at fair value based on market rates. Adjustment arising from the comparison of the amount measured based on the rate agreed upon is accounted for as deferred revenue (Note 19).

u) Revenue recognition

Revenues substantially correspond to value of considerations received or receivable arising from the provision of telecommunications or communications services, the sale of goods, advertising and other revenue, and are stated net of taxes, discounts or returns (in case of sale of goods) thereon. Revenues and expenses are stated on the accrual basis of accounting.  

Revenue is recognized when it is probable that future economic benefits will flow to the Company or its subsidiaries, when it can be reliably measured, costs incurred in the transaction can be measured, the risks and rewards have been substantially transferred to the buyer and when specific criteria have been met for each of the Company’s activities.

Consolidated revenues of the Company comprise basically telecommunication services regarding voice, data and digital services, broadband, TV and additional telecommunication services that are offered to customers through fixed-price traffic packs (paid on a monthly basis) or based on customers’ consumption, remuneration for network usage, advertising and sale of goods.

u.1) Recognition of revenues from telecommunication services

Revenues from telecommunication, data and digital services, broadband services provided are recorded on an accrual basis based on the amounts agreed upon. Local and long-distance calls are billed by the measurement process under legislation in force. The services billed on fixed monthly amounts are calculated and accounted for on a straight-line basis. Unbilled revenues from the last billing up to the balance sheet date are recognized in the month in which the service is provided.

Revenues related to sale of public phone cards and pay-as-you-go credit for cellphones as well as the respective taxes are deferred and recognized in the income statement to the extent that the services are effectively rendered.

Revenues from equipment lease contracts classified as finance lease agreement (TData’s Soluciona TI product) are recognized on installation of equipment whereupon effective transfer of risk takes place. Revenue is recognized at present value of future minimum payments provided for in the agreement.

F-37

Revenues from services are basically subject to the following indirect taxes: ICMS or ISS (as applicable), PIS and COFINS.

u.2) Recognition of revenue and cost from sales of goods

Revenues and cost of sales (mobile phones, simcards and accessories) are recorded when risks and rewards inherent in such goods are transferred to buyers.

Sales made in own stores are recognized upon sale to end consumer. Revenues and costs of sales made by accredited dealers are deferred and recognized in P&L when the device is activated, limited to 90 days from the sale date.

u.3) Customer loyalty program

The Company has a loyalty points program that enables customers to accumulate points when they pay bills regarding the usage of the services offered. The accumulated points may be exchanged for telephone sets or services, conditional upon obtaining a minimum balance of points by customer. The consideration received is allocated to the cost of sets or services at fair value. The fair value of points is determined by dividing the amount of discount granted by the number of points necessary for the redemption based on the points program. The portion of revenue related to the fair value of the accumulated balance of points generated is deferred and recognized as revenue upon redemption of points.

The number of points to be accounted for is determined through statistical techniques that consider assumptions and historical data on expected redemption rates, expiration percentages and cancellation of points, among other factors. These estimates are subject to variations and uncertainties due to changes in the behavior of customer redemptions.

u.4) Membership fee and promotional campaigns

Participation fees paid for promotional campaigns by customers of the Company are deferred and recorded in P&L throughout the duration of such campaign.

u.5) Agreements combining more than one element Commercial packages offered by the Company that combine different elements are analyzed to determine whether it is necessary to separate the different elements identified, adopting the recognition criterion that is most adequate to each situation. Total revenue generated by the package sale is distributed among its elements, based upon their respective fair values. The fair value determination of each element then identified implies the need for complex estimates given the nature of the business. A possible change in fair values estimates could affect the distribution of revenues between components and consequently the deferred revenue. u.6) Advertising Revenues from advertising are recognized in income during the advertising period. v) Financial income (expenses) These include interest, and monetary and exchange variations arising from short-term investments, derivative transactions, loans, financing, debentures, present value adjustments of transactions that generate monetary assets and liabilities and other financial transactions. These are recognized on an accrual basis when earned or incurred by the Company.

F-38

For all financial instruments measured at amortized cost and interest-yielding financial assets classified as available for sale, interest income or expense is recognized using the effective interest method, which exactly discounts estimated future cash payments or receipts over the expected life of the financial instrument or, where appropriate, a shorter period, to the net carrying amount of the financial asset or liability.

w) Post-retirement benefit plans

The Company individually sponsor pension funds of post-retirement benefits for active and retired employees, in addition to a multisponsor supplementary retirement plan and health care plan for former employees. Contributions are determined on an actuarial basis and recorded on an accrual basis. Liabilities relating to defined benefit plans are determined based on actuarial evaluations at each year end, in order to ensure that sufficient reserves have been set up for both current and future commitments.

Actuarial liabilities related to defined benefit plans were calculated using the projected unit credit method. Actuarial gains and losses are recognized immediately in equity (in other comprehensive income).

For plans with defined contribution characteristics, the obligation is limited to the contributions payable, which are recognized in the P&L in the respective accrual periods.

The asset or liability related to defined benefit plan to be recognized in financial statements corresponds to the present value of the obligation for the defined benefit (using a discount rate based on long-term National Treasury Notes “NTNs”), less fair value of plan assets that will be used to settle the obligations. Plan assets are assets held by a privately-held supplementary pension plan entity. Plan assets are not available to the Company’s creditors or those of its subsidiaries and cannot be paid directly to the Company. The fair value is based on information on market prices and, in case of securities quoted, on purchase price disclosed. The value of any defined benefit asset then recognized is limited to the present value of any economic benefits available as a reduction in future plan contribution from the Company.

Actuarial costs recognized in the income statement are limited to the service cost and cost of interest on the defined benefit plan obligation. Any changes in the measurement of plan assets and obligations are initially recognized in other comprehensive income, and immediately reclassified to retained earnings in P&L.

The Company manages and individually sponsor a health care plan for retired employees and former employees with fixed contributions to the plan, in accordance with Law No. 9656/98 (which provides for private health care and health insurance plans). As provided for in articles 30 and 31 of said law, participants shall have the right to the health care plan in which they participated while they were active employees. 

x) Significant accounting judgments, estimates and assumptions

The preparation of the financial statements requires management to make judgments, estimates and adopt assumptions supported by valuation bases used in accounting estimates. The accounting estimates involved in the preparation of these financial statements were based on objective and subjective factors, considering management’s judgment for determining the adequate amounts to be recorded in the financial statements.

F-39

Settlement of transactions involving these estimates may result in amounts significantly different from those recorded in the financial statements due to the uncertainties inherent in their estimate process.

Significant assumptions concerning sources of uncertainty in future estimates and other significant sources of estimation uncertainty at the balance sheet date, involving a significant risk of causing a material adjustment to the carrying amount of assets and liabilities, are as follows: 

x.1) Impairment of non-financial assets

An impairment loss exists when the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, which is the higher of fair value less cost to sell and value in use. The calculation of fair value less cost to sell is based on information available on transactions for sale of similar assets or market prices less additional costs to dispose of the asset. The calculation of value in use is based on the discounted cash flow model. The recoverable amount is sensitive to the discount rate used in the discounted cash flow method, as well as expected future cash receipts and growth rate used for extrapolation purposes.

The Company regularly analyzes the performance of the defined cash generating unit in order to identify any impairment of goodwill and its other assets. Determination of the recoverable amount of the cash generating unit to which goodwill is attributed includes use of assumptions and estimates and requires use of significant accounting judgment and criterion. 

x.2) Post-retirement benefit plans

The cost of pension plans with defined benefits and other post-employment health care benefits and the present value of the pension obligation are determined using actuarial valuation methods. Actuarial valuation involves use of assumptions about discount rates, future salary increases, mortality rates and future increases in pension and annuity benefits. The obligation for defined benefits is highly sensitive to changes in these assumptions. All assumptions are reviewed on an annual basis.

The mortality rate is based on publicly available mortality tables in the country. Future salary increases and pension increases are based on expected future inflation rates for the country.

x.3) Fair value of financial instruments

When the fair value of financial assets and liabilities stated in the balance sheet cannot be obtained in active markets, it will be determined using valuation techniques, including the discounted cash flow method. Data for these methods is based on those adopted in the market, whenever possible. However, when this is not feasible, a certain level of judgment is required for fair value determination. Judgment includes consideration of the inputs used, such as liquidity risk, credit risk and volatility. Changes in the assumptions about these factors could affect the reported fair value of financial instruments.

x.4) Property, plant and equipment and finite-lived intangible assets

The accounting treatment of investment in fixed and intangible assets includes estimating useful life period for depreciation purposes and the fair value at the date of acquisition, particularly for assets acquired in business combinations.

Useful life determination requires estimates regarding the expected technological developments and alternative uses of assets. The hypotheses related to the technological aspect and its future development imply a significant level of analysis, considering the difficulties in forecasting time and nature of future technological changes.

F-40

x.5) Revenue recognition – Customer Loyalty Program

The Company estimates the fair value of points attributed under the customer loyalty program by applying statistic techniques. Inputs for the model include assumptions about expected redemption rates, the mix of products that will be available for future redemption and customers’ preference in relation to points use.   Since issued points do not expire, these estimates are subject to significant uncertainties.

x.6) Agreements combining more than one element

The fair value determination of each element in a multiple element agreement requires complex estimates given the nature of the business. A possible change in fair value estimates could affect the distribution of revenues between components and consequently the deferred revenues.

x.7) Taxes

There are uncertainties regarding the interpretation of complex tax regulations and the amount and timing of future taxable profits. The Company set up provisions, based on reasonable estimates, for the possible consequences of audits by tax authorities in respective jurisdictions in which they operate. The amount of these provisions is based on various factors, such as previous tax audit experience and different interpretations of tax regulations by the taxable entity and by the relevant tax authority. Such differences in interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective domicile of the Company.

The Company evaluate the recoverability of deferred tax assets based on estimates of future profits. This recoverability ultimately depends on the ability of the Company to generate taxable profits over the period in which the deferred tax asset is deductible. The analysis considers the reversal period of deferred tax liabilities, as well as estimates of taxable profits, based on updated internal projections reflecting the latest trends.

Determining the proper classification of the tax items depends on several factors, including an estimate of the period and the realization of the deferred tax asset and the expected date of payments of these taxes. The actual flow of receipt and payment of income tax could differ from estimates made by the Company, as a result of changes in tax laws or of unexpected future transactions that may impact tax balances.

x.8) Provisions for tax, labor, civil and regulatory proceedings

Provisions are recognized when the Company has a present obligation arising from a past event, settlement of which requires an outflow of resources rated as probable and when it can be reliably estimated. This obligation can be legal or constructive, derived from, among other factors, regulations, contracts, customary practices or public commitments that expose third parties to a valid expectation that the Company will assume certain responsibilities. The determination of the provision is based on the best estimate of the disbursement required to settle the corresponding obligation, considering the information available as of the closing date, including the opinion of independent experts, such as legal advisors.

x.9) Revenue recognition - revenue from unbilled services

The Company has billing systems for services with intermediate cut-off dates.

c) Goodwill impairment testing

The Company assessed recoverability of goodwill carrying amount based on the value in use and discounted cash flow method.

F-52

The process for determination of the value in use involves the use of assumptions, judgments and estimates on cash flows, such as revenue, cost and expense growth rates, estimated future investments and working capital and discount rates. The assumptions about cash flow increase projections were based on management’s estimates, market studies and macroeconomic projections. Future cash flows were discounted at the WACC (Weighted Average Cost of Capital) rate.

Consistent with the economic analysis techniques, the assessment of value in use is made for a period of five (5) years, and thereafter, considering the perpetuity of the assumptions based on the capacity of business continuity for an indefinite time. Management considered that the period of 5 years is adequate, based on its past experience in preparing cash flow projections. Such understanding is in line with paragraph 35 of IAS 36 – Impairment of Assets.

The growth rate used to extrapolate the projections beyond the 5 years period was 4.5% and 5.0% in 2017 and 2016, respectively. Estimated future cash flows were discounted at the pre tax rate of 13.58% in 2017 (14.75% in 2016), also at nominal amounts. 

The inflation rate for the period analyzed in the projected cash flows was 4.0% in 2017 (4.5% in 2016).

Key assumptions were based on the Company’s historical performance and reasonable macroeconomic assumptions grounded on financial market projections, documented and approved by the Company’s management.

Based on annual impairment testing of the Company’s intangible assets, prepared using projections considering the financial statements at December 31, 2017 and 2016, growth projections and operating results for the year ended December 31, 2017 and 2016, no impairment losses or evidence of losses were identified, since value in use is higher than net carrying amount as of the assessment date.

c.1) Key assumptions used in the calculation of value in use:

The value in use is mainly impacted by the following assumptions:

·Revenue Growth: is based on the observation of the historical behavior of each revenue line, as well as trends based on market analysis. The projected revenue differs between product lines and services with a tendency of growth in broadband services, pay TV and IT compared to voice services (fixed).

·Growth in operating margin: takes into account the historical margin estimate of price correction, as well as ongoing projects with the aim of greater cost efficiency.

·Capex volume: we considered the projects in progress aiming at the best efficiency of use of CapEx associated with the need to increase capacity and coverage in line with the growth in revenue provided under the long-term plan. The Capex volume may also be impacted by inflation and currency fluctuations.

·Discount rate: represents the assessment of risks in the current market. The calculation of the discount rate is based on the Company’s specific circumstances and derived from the weighted average cost of capital (WACC). The WACC takes into account both debt and equity. The cost of equity is derived from the expected return on investment by Company investors. The cost of debt is based on loans with interest income that the Company is obliged to honor. The specific risk segment is incorporated by applying individual beta factors.

c.2) Sensitivity to changes in assumptions

The Company carries out a sensitivity analysis of the impairment test by considering reasonable changes in the main assumptions used in such test.

The following maximum increases or decreases, expressed in percentage points (p.p.) were assumed for the years ended December 31, 2017 and 2016:

F-53

Changes in key assumptions	In percentage points (p.p)
Financial variables
Discount rate		+ / - 1.0
Perpetuity growth rates		+ / - 0.5
Operating variables
OIBDA Margin		+ / - 2.0
Capex/Revenues Margin		+ / - 1.0

The sensitivity analysis performed at year-end 2017 and 2016 indicates that there are no significant risks arising from possible changes in the financial and operating variables, considered individually. In other words, the Company considers that within the above (reasonably wide) limits, no losses would be recognized.

a) Provisions and labor contingencies

	Amounts involved
Nature/Degree of Risk	12/31/17	12/31/16
Provisions - probable losses	980,596	1,382,957
Possible losses	261,876	293,146

Labor provisions and contingencies involve labor claims filed by former employees and outsourced employees (the latter alleging subsidiary or joint liability) claiming for, among other issues, overtime, salary equalization, post-retirement benefits, allowance for health hazard and risk premium, and matters relating to outsourcing.

The Company is also a defendant in labor claims filed by retired former employees who are covered by the Retired Employees Medical Assistance Plan ("PAMA"), who, among other issues, are demanding the cancellation of amendments to this plan. Most of these claims await a decision by the Regional Labor Court of São Paulo and the Superior Labor Court. Based on the opinion of its legal counsel and recent decisions of the courts, management considers the risk of loss in these cases as possible. No amount has been specified for these claims, since is not possible to estimate the cost to the Company in the event of loss.

Provisions - probable losses	1,055,877	1,039,357
Possible losses	2,858,796	2,574,836

c.1) Provisions for probable civil losses

Management and its legal counsel understand that losses are probable in the following civil proceedings:

·The Company is party to proceedings involving rights to the supplementary amounts from shares calculated on network expansion plans since 1996 (supplement of share proceedings). These proceedings are at different stages: lower courts, court of justice and high court of justice. At December 31, 2017, consolidated provisions totaled R$324,232 (R$256,276 at December 31, 2016).

c.2) Civil contingencies assessed as possible losses

Management and its legal counsel understand that losses are possible in the following civil proceedings:

·Collective Action filed by SISTEL Participants' Association (ASTEL) in the state of São Paulo, in which SISTEL associates in the state of São Paulo challenge the changes made in the health insurance plan for retired employees ("PAMA") and claim for the reestablishment of the prior "status quo".  This proceeding is still in the appeal phase, and awaits a decision on the Interlocutory Appeal filed by the Company against the decision on possible admission of the appeal to higher and supreme courts filed in connection with the Court of Appeals' decision, which changed the decision rendering the matter groundless. The amount cannot be estimated, and the claims cannot be settled due to their unenforceability because it entails the return to the prior plan conditions.

·Civil Class Actions filed by ASTEL, in the state of São Paulo, and by the Brazilian National Federation of Associations of Retirees, Pensioners and Pension Fund Members of the Telecommunications Industry (FENAPAS), both against SISTEL, the Company and other carriers, in order to annul the spin-off of the PBS private pension plan, alleging, in short, the "windup of the supplementary private pension plan of the SISTEL Foundation", which led to various specific mirror PBS plans, and corresponding allocation of funds from technical surplus and tax contingencies existing at the time of the spin-off.  The amount cannot be estimated, and the claims cannot be settled due to their unenforceability because this involves the return of the spun-off assets of SISTEL relating to telecommunication carriers of the former Telebrás System.

F-60

·The Company is party to other civil claims, at several levels, related to service rendering rights. Such claims have been filed by individual consumers, civil associations representing consumer rights or by the Bureau of Consumer Protection (PROCON), as well as by the Federal and State Public Prosecutor's Office. The Company is also party to other claims of several types related to the ordinary course of business. At December 31, 2017, the consolidated amount totaled R$2,827,071 (R$2,559,252 at December 31, 2016).

·TGLog (company controlled by TData) is a party to the civil enforcement action process in the 3rd Civil Court of Barueri - SP for the allegation of contractual noncompliance with the transportation of goods. At December 31, 2017, the amount was R$178 (R$1,377 at December 31, 2016).

·Terra Networks (company controlled by TData) is a party to: (i) supplier action related to the transmission of events; (ii) PROCON fine (annulment action); (iii) indemnification action related to the use of content; (iv) ECAD action on copyright collection; and (v) claim actions filed by former subscribers regarding unrecognized collection, collection of undue value and contractual noncompliance. At December 31, 2017, the amount was R$17,340.

·The Company has received notices regarding noncompliance with the Customer Service (SAC) Decree. The Company is currently party to various lawsuits (administrative and legal proceedings). At December 31, 2017 and at December 31, 2016, the amount was R$14,207.

·Intelectual Property: Lune Projetos Especiais Telecomunicação Comércio e Ind. Ltda. (Lune), a Brazilian company, filed an action on November 20, 2001 against 23 wireless carriers claiming to own the patent for caller ID and the trademark "Bina".  The purpose of that lawsuit was to interrupt provision of such service by carriers and to seek indemnification equivalent to the amount paid by consumers for using the service.

An unfavorable decision was handed down determining that the Company should refrain from selling mobile phones with Caller ID service ("Bina"), subject to a daily fine of R$10,000.00 (Ten thousand reais) in case of noncompliance. Furthermore, according to that decision, the Company must pay indemnification for royalties, to be calculated in settlement. Motions for Clarification were proposed by all parties and Lune's motions for clarification were accepted since an injunctive relief in this stage of the proceedings was deemed applicable. A bill of review appeal was filed in view of the current decision which granted a stay of execution suspending that unfavorable decision until final judgment of the review. A bill of review was filed in view of the sentence handed down on June 30, 2016, by the 4th Chamber of the Court of Justice of the Federal District, in order to annul the lower court sentence and remit the proceedings back to the lower court for a new examination. At the present time, we await the judgment of the regimental grievance filed against a decision prior to the judgment, which rejected the application of the former lawyers of Lune as assistants of the author.  There is no way to determine the extent of potential liabilities with respect to this claim.

·The Company and other wireless carriers figure as defendants in several lawsuits filed by the Public Prosecutor's Office and consumer associations to challenge imposition of a period to use prepaid minutes. The plaintiffs allege that the prepaid minutes should not expire after a specific period. Conflicting decisions were handed down by courts on the matter, even though the Company understands that its criteria for the period determination comply with ANATEL standards.

d) Provisions and regulatory contingencies

	Amounts involved
Nature/Degree of Risk	12/31/17	12/31/16
Provisions - probable losses	1,103,792	828,934
Possible losses	5,065,907	5,018,205

d.1) Provisions for regulatory contingencies assessed as probable losses

The Company is party to administrative proceedings against ANATEL, filed based on an alleged failure to meet sector regulations, and to judicial proceedings to contest sanctions applied by ANATEL at the administrative level. At December 31, 2017, consolidated provisions totaled R$1,103,792 (R$828,934 at December 31, 2016).

d.2) Regulatory contingencies assessed as possible losses

According to the Company's management and legal counsel, the likelihood of loss of the following regulatory civil proceedings is possible:

·The Company is party to administrative proceedings filed by ANATEL alleging noncompliance with the obligations set forth in industry regulations, as well as legal claims which discuss the sanctions applied by ANATEL at the administrative level. At December 31, 2017, the consolidated amount was R$5,065,907 (R$5,018,205 at December 31, 2016).

·Administrative and judicial proceedings discussing payment of a 2% charge on interconnection services revenue arising from the extension of right of use of SMP related radio frequencies. Under clause 1.7 of the authorization term that grants right of use of SMP related radio frequencies, the extension of right of use of such frequencies entails payment every two years, during the extension period (15 years) of a 2% charge calculated on net revenues from the service provider's Basic and Alternative Plans of the service company, determined in the year before that of payment.

However, ANATEL determined that in addition to revenues from Service Plans, the charge corresponding to 2% should also be levied on interconnection revenues and other operating revenues, which is not stipulated in clause 1.7 of referred Authorization Term.

Considering, based on the provisions of the Authorization Terms, that revenue from interconnection services should not be included in the calculation of the 2% charge for radiofrequency use right extension, the Company filed administrative and legal proceedings challenging these charges, based on ANATEL's position.

d.3) Term of Conduct Adjustment ("TAC")

The Board of Directors of ANATEL approved, on October 27, 2016, the Company's TAC. On September 27, 2017, this instrument was judged by the Brazilian Court of Audit ("TCU"), with the instruction of recommendations and determinations to ANATEL for the continuation of the analysis of the instrument.

a) Capital

According to its Articles of Incorporation, the Company is authorized to increase its share capital up to 1,850,000,000 common and preferred shares. The Board of Directors is the competent body to decide on any increase and consequent issue of new shares within the authorized capital limit.

Nevertheless, Brazil’s Corporation Law (Law nº 6404/76, Article 166, item IV) - establishes that capital may be increased by means of a Special Shareholders’ Meeting resolution to decide about amendments to the Articles of Incorporation, if authorized capital increase limit has been reached.

Capital increases do not necessarily observe the proportion between the number of shares of each class to be maintained, however the number of non-voting or restricted-voting preferred shares must not exceed 2/3 of total shares issued.

Preferred shares are non-voting, except for cases set forth in Articles 9 and 10 of the  Articles of Incorporation, but have priority in the event of reimbursement of capital, without premium, and are entitled to dividends 10% higher than those paid on common shares, as per article 7 of the Company's Articles of Incorporation and item II, paragraph 1, article 17 of Law No. 6404/76.

Preferred shares are also entitled to full voting rights if the Company fails to pay the minimum dividend to which they are entitled for three consecutive financial years and this right will be kept until payment of said dividend.

Subscribed and paid-in capital at December 31, 2017 and 2016 amounted to R$63,571,416, divided into shares without par value, held as follows:

29)  SHARE-BASED PAYMENT PLANS

Telefónica, as the Company's parent company, has different share-based payment plans based on the share quotes, which were also offered to management and employees of its subsidiaries, including Telefônica Brasil.

The fair value of these options is estimated on the grant date, based on a binomial pricing model reflecting terms and conditions of instruments granted.

The Company reimburse Telefónica for the amount of the fair value of the benefits granted to management and employees on the grant date.

The main plans in effect at December 31, 2017 and 2016 are detailed below:

a)Performance & Investment Plan (“PIP”)

Telefónica's General Shareholders’ Meeting held on May 18, 2011 approved a long-term program for using Telefónica stock options to reward senior management's global commitment, outstanding performance and high potential by awarding Telefónica S.A. shares.

F-83

Participants are not required to pay for their initial stock options and may increase the number of shares to be received at the end of the plan if they decide to make a joint investment in their PIP, which requires a participant to buy the equivalent of 25% of the initial shares awarded by Telefónica and hold them until the end of the cycle, when Telefónica will add another 25% in addition to the initial amount of shares in their co-investment.

Initially, the plan is expected to remain effective for 3 years. The cycles are independent of each other. The number of shares is reported at the beginning of each cycle and will be transferred to participants 3 years after the grant date assuming these professionals have met their targets.

The granting of shares is conditional on: (i) maintenance of an active employment relationship within the Telefónica Group on the cycle consolidation date; and (ii) achievement, by Telefónica, of results representing fulfillment of the objectives established for the plan.

The level of success is based on a comparison of the growth in shareholder earnings, considering stock quotations and dividends (Total Shareholder Return- TSR) with the growth in TSR for companies of the Group in an established basis of comparison.

In 2014, the Company approved the extension of this program for another 3 cycles of 3 years each, beginning October 1, 2014 until September 30, 2017. The number of shares is stated at the beginning of the cycle and three years after grant date, and shares are transferred to participants as long as TSR targets are met.

The 2013-2016 cycle takes place in June 2016 and the TSR was not achieved, therefore Telefónica shares were not awarded to the Company’s executives.

The 2014-2017 cycle takes place in September 2017 and the TSR was not achieved, therefore Telefónica shares were not awarded to the Company’s executives.

The 2015-2018 (October 1, 2015 the September 30, 2018): with 84 active Company executives (including 2 executives appointed under the Articles of Incorporation of the Company), hold the right to potentially receive 471,654 Telefónica shares (includes initial amounts and co-investment).

At December 31, 2017, the value of Telefónica’ share price was Eur 8.1950.

b)Talent for the Future Share Plan (“TFSP”)

Telefónica's 2014 General Shareholders’ Meeting approved a long-term program to reward the global commitment, outstanding performance and high potential of its executives by awarding Telefónica shares.

Participants are not required to pay for their initial options. Initially, the plan is expected to remain effective for 3 years. The cycle began on October 1, 2014 until September 30, 2017. The number of shares is reported at the beginning of the cycle and shares will be transferred to participants 3 years after grant date if their targets have been met.

The granting of shares is conditional upon: (i) maintenance of an active employment relationship within the Telefónica Group on the cycle consolidation date; and (ii) achievement, by Telefónica, of results representing fulfillment of the objectives established for the plan. The level of success is based on a comparison of growth in Telefónica shareholder earnings, including their quotations and dividends (Total Shareholder Return - TSR) compared with the growth in TSR for Companies of the Group in an established basis of comparison.

The 2014-2017 cycle takes place in September 2017 and the TSR was not achieved, therefore Telefónica shares were not awarded to the Company’s executives.

The 2015-2018 cycle (October 1, 2015 to September 30, 2018): with the right to potentially receive 83,500 Telefónica shares (includes initial amounts).

F-84

At December 31, 2017, the value of Telefónica’ share price was Eur 8.1950.

c)Global Employee Share Plan (“GESP”)

At the Telefónica General Shareholders’ Meeting held on May 30, 2014, a share purchase plan under tax incentive was approved, intended for employees of Telefónica Group at the international level, including the employees of the Company. This plan offers the possibility of acquiring Telefónica shares with the commitment of the later to deliver free of charge to participants a given number of its shares, whenever certain requirements are met.

Initially, the plan was expected to remain effective for 2 years. Employees enrolled in the plan were able to acquire Telefónica shares by making monthly contributions of 25 to 150 euros (or the equivalent in local currency) totaling at most 1,800 euros over 12 months (acquisition period).

The delivery of shares occurred after the vesting period of the plan, as of July 31, 2017, and was conditional on: (i) the permanence in the Company during the 2-year program period (vesting period), subject to certain special conditions related to terminations; and (ii) the exact number of shares to be granted at the end of the vesting period depends on the number of shares acquired and held by employees. Thus, employees enrolled with the plan, who remained in the Telefónica Group and who have held the shares acquired for an additional period of over 12 months after the end of the purchase period, will be entitled to receive one free share for each share they have acquired and held until the end of the vesting period.

The cycle was finalized on July 31, 2017, with the delivery of the net shares of withholding income tax.

The expenses of the Company with the share-based compensation plans described above, where applicable, are recorded as personnel expenses, divided into the groups Cost of Services, Selling expenses and General and Administrative Expenses (Note 24), corresponding to R$7,013 and R$21,952 for the years ended December 31, 2017 and 2016.

30)  PENSION PLANS AND OTHER POST-EMPLOYMENT BENEFITS

The plans sponsored by the Company and related benefit types are as follows:

Plan	Type	Entity	Sponsor
PBS-A	Defined benefit (DB)	Sistel	Telefônica Brasil, jointly with other telecoms resulting from privatization of the Sistema Telebrás
PAMA / PCE	Defined benefit (DB)	Sistel	Telefônica Brasil, jointly with other telecoms resulting from privatization of the Sistema Telebrás
Healthcare - Law No. 9656/98	Defined benefit (DB)	Telefônica Brasil	Telefônica Brasil, TData, Terra Networks and TGLog
CTB	Defined benefit (DB)	Telefônica Brasil	Telefônica Brasil
Telefônica BD	Defined benefit (DB)	VisãoPrev	Telefônica Brasil
TCOPREV	Hybrid	VisãoPrev	Telefônica Brasil
VISÃO	Defined contribution (DC) / Hybrid	VisãoPrev	Telefônica Brasil, TData, Terra Networks and TGLog

The actuarial valuation of the plans was made in December 2017 and 2016, based on the registration of the participants held on the following dates:

•   Post-Employment Health Benefits Plans

The actuarial valuation made for the PAMA health plan used the registration of the participants with a base date of October 31, 2017, projected for December 31, 2017 and the registration of the participants with a base date of July 31, 2016, projected for 31 of December 2016.

The actuarial valuation carried out for the health plan Law No. 9,656 / 98 used the register of the participants with a base date of October 31, 2017, projected for December 31, 2017 and the registration of the participants with a base date of August 31, 2016 , projected for December 31, 2016.

F-85

•   Post-employment Social Security Plans

The actuarial valuation made for the CTB pension plan used the registration of the participants with a base date of August 31, 2017, projected for December 31, 2017 and the registration of the participants with a base date of July 31, 2016, projected for 31 of December 2016.

The actuarial valuation made for all other pension plans (PBS-A, Telefônica BD, Tcoprev and Visão plans) used the register of the participants with a base date of July 31, 2017, projected for December 31, 2017 and the with a base date of July 31, 2016, projected for December 31, 2016.

The Company has participation in the decisions that directly affect the governance of the plans, with members nominated for both the Deliberative Council and the Fiscal Council of the administrators Sistel and VisãoPrev.

The defined benefit obligation is made up of different components, according to the pension characteristic of each plan, and may include the actuarial liabilities of supplementary pension liabilities, health care benefits to retirees and dependents or compensation for death or disability of members. This liability is exposed to economic and demographic risks, such as: (i) increases in medical costs that could impact the cost of health care plans; (ii) salary growth; (iii) long-term inflation rate; (iv) nominal discount rate; and (v) life expectancy of members and pensioners.

The fair value of plan assets is primarily comprised of fixed income investments (NTN's, LFT’s, LTN's, repurchase agreements, CDBs, debentures, letters of guarantee and FIDC shares) and equity investments (highly liquid, well regarded, large company shares and investments in market indices). Due to the concentration of fixed income and floating rate investments plan assets are mainly exposed to the risks inherent in the financial market and economic environment such as: (i) market risk in the economic sectors where variable income investments are concentrated; (ii) risk events that impact the economic environment and market indices where variable income investments are concentrated; and (iii) the long-term inflation rate that may erode the profitability of fixed-income investments at fixed rates.

The companies that administer post-employment benefits plans sponsored by the Company (VisãoPrev and Sistel) seek to meet the flows of assets and liabilities through the acquisition of fixed income securities and other long-term assets.

With the exception of the CTB deficit plans and the healthcare plan under Law No. 9656/98, generally all benefit plans that have fund constituted, present a surplus position. The economic benefit recorded in the Company's assets or that of its subsidiaries does not reflect the total surplus determined in these plans. The economic benefit stated under assets considers only the portion of the surplus which presents a real possibility of recovery. The means of plan surplus recovery is solely through reductions in future contributions and given that not all plans currently receive enough contributions for full recovery of surpluses, the economic benefit recorded under assets is limited to the total possible recovery amount in accordance with projected future contributions.

The position of plan assets is at December 31, 2017 and 2016, respectively, and plan assets were apportioned based on the company’s actuarial liabilities in relation to the total actuarial liabilities of the plan.

The actuarial gains and losses generated in each year are immediately recognized in equity (in other comprehensive income).

The following is a summary of the pension plans and other post-employment benefits:

F-86

a)Post-retirement Health Plans

a.1) Healthcare Plan to Retirees and Special Coverage Program (PAMA and PAMA-PCE)

The Company, together with other companies of the former Telebrás System, at shared cost, sponsor health care plans (PAMA and PAMA-PCE) for retirees. These plans are managed by Fundação Sistel and are closed plans, not admitting new members.

Contributions to the plans are determined based on actuarial valuations prepared by independent actuaries, in accordance with the rules in force in Brazil. The funding procedure is the capitalization method and the sponsor’s contribution is at the fixed percentage of payroll of employees covered by the Telefônica BD plan.

a.2) Health care plan – Law No. 9656/98

The Company manages sponsor a health care plan to retired employees and former employees with fixed contributions to the plan, in accordance with Law No. 9656/98.

As provided for in articles 30 and 31 of said law, participants shall have the right to the health care plan in which they participated while they were active employees. Benefitted participants are classified as retirees and their dependents and dismissed employees and their dependents.

Retirees and dismissed employees, in order to keep their right to the benefits, must make contributions to the plan in accordance with the contribution tables by age bracket established by carriers and/or insurance companies.

b)Post-Employment Pension Plans

They include the PBS Assisted Plans (“PBS-A"), CTB, Telefônica DB, Tcoprev and Visão.

On December 9, 2016, Visão Prev obtained approvals from the National Supplementary Pension Authority ("PREVIC") for the incorporation of Vivo Prev and Visão TGestiona plans to the Visão Telefônica plan. In this way, as of January 1, 2017, all participants in Vivo Prev and Visão TGestiona plans became participants in the Visão Telefônica plan. This unification preserves all vested rights, and gives participants of the incorporated plans access to the benefits of the Visão Telefônica plan.

The main purpose of the mergers is to create greater synergy of the benefits offered to the participants, as well as to reduce administrative and operational costs of the plans, as well as to improve administrative efficiency.

F-87

The following describes the key information about post-retirement pension plans.

b.1) PBS Assisted Plan (PBS-A)

The PBS-A plan is a defined benefit private pension plan managed by Sistel and sponsored by the Company jointly with the other telecommunications companies originating in the privatization of the Telebrás system. The plan is subject to funding by sponsors in case of any asset insufficiency to ensure pension supplementation of participants in the future.

The PBS-A plan comprises assisted participants of the Sistel Benefit Plan who were already retirees on January 31, 2000, from all the participating sponsors, with joint liability of all sponsors to the plan and Sistel.

Although the PBS-A plan has assets in excess of actuarial liabilities at December 31, 2017 and 2016, such surplus was not recognized due to lack of legal provision in relation to refund thereof, in addition, since it is not a contributive plan, it is not possible to make any deduction from future contributions.

b.2) CTB Plan

Contributions to the CTB plan are determined based on actuarial valuations prepared by independent actuaries, in accordance with the rules in force in Brazil. The funding procedure is the capitalization method and the sponsor’s contribution is a fixed percentage of payroll of employees covered by the plan.

The Company also individually manages and sponsors the CTB Plan, originally provided to former employees of Companhia Telefônica Brasileira (“CTB”) who were in the Company in 1977, with whom an individual retirement concession agreement was executed to encourage their resignation. This is an informal pension supplementation benefit paid to former employees directly by the Company. These plans are closed, and no other members are admitted.

b.3) Telefônica DB Plan

The Company individually sponsor defined benefit retirement plan, the Telefônica DB Plan.

In order to improve allocation of Telefôncia DB plan assets and analyze the coverage ratio of plan obligations in future years, a stochastic ALM study was prepared by Visão Prev and Willis Towers Watson. This ALM study aimed at projecting the ratio between coverage of liabilities (solvency ratio) and the risk of mismatching measured by the standard deviation of the solvency ratio. The study concluded that the plan present sustainable projection of their coverage ratio with the current investments portfolio.

F-88

At the time of the concession, a benefit is calculated, which will be paid in a lifelong form and updated by inflation. This plan is not open to new accessions.

The contributions are defined according to the costing plan, which is calculated considering financial, demographic and economic hypotheses in order to accumulate enough resources to pay the benefit to the participants who are already receiving and to the new pensions.

b.4) Tcoprev Plan

The Company sponsors, individually, the Tcoprev Plan, a hybrid plan for defined benefits and defined contribution of pension benefits, managed by Visão Prev.

The contributions to the Tcoprev plan are: (i) basic contribution, with contributions made by the participant and sponsor; and (ii) voluntary and sporadic contributions, with contribution made only by the participant. In addition to these contributions, the sponsor can make the variable contribution, of an eventual character, being apportioned proportionally to the basic contribution of the participant.

In order to improve allocation of Tcoprev plan assets and analyze the coverage ratio of plan obligations in future years, a stochastic ALM study was prepared by Visão Prev and Willis Towers Watson. This ALM study aimed at projecting the ratio between coverage of liabilities (solvency ratio) and the risk of mismatching measured by the standard deviation of the solvency ratio. The study concluded that the Tcoprev plan present sustainable projection of its coverage ratio with the current investments portfolio.

b.5) VISÃO Plans

The Visão Telefôncia and Visão Multi plans will hereinafter be shown jointly under the name VISÃO, due to their similarity.

The Company sponsor defined contribution pension plans with defined benefit components (hybrid plans), i.e. the VISÃO Plans, managed by Visão Prev. The contribution is attributed to each subsidiary in the economic and demographic proportion of its respective obligation to the plan.

F-89

The contributions made by the Company related to defined contribution plans totaled R$43,702 at December 31, 2017 (R$37,879 at December 31, 2016).

The contributions to the Visão Telefôncia and Visão Multi plans are: (i) basic and additional contribution, with contributions made by the participant and sponsor; and (ii) additional, sporadic and specific contribution, with contribution made only by the participant.

In addition, the participant has the possibility to choose one of the five investment profiles to apply their balance, they are: Super Conservative, Conservative, Moderate, Aggressive and Aggressive Fixed Income Long Term.

Further to the assumptions stated above, other assumptions common to all plans were adopted in 2016 as follows: (i) Long-term inflation rate  4.5%; and (ii) Annual increase in the use of medical services according to age: 4.0%.

c.12) Changes in actuarial assumptions in relation to the prior year

In order to adjust some actuarial assumptions to the economic and demographic reality, a study was conducted for the plans administered by Visão Prev and Sistel, which adopted the definition of the assumptions in their Deliberative Councils.

The main economic and financial assumptions that have changed in relation to the previous fiscal year and that interfere with the defined benefit liability are: (i) rates for discount to present value of the defined benefit liability; (ii) long-term inflation rate; (iii) rate of future wage growth; (iv) rate of growth of medical costs; and (v) annual nominal index of adjustment of social security benefits.

The impacts on the plans’ defined benefit liabilities due to the new definition of the actuarial assumptions are as follows:

	Post-retirement pension plans	Post-retirement health plans	Total
Defined benefit liability, based on current actuarial assumptions	1,861,651	1,050,576	2,912,227
Defined benefit liability, based on prior-year actuarial assumptions	1,756,118	956,108	2,712,226
Difference from change in actuarial assumptions	105,533	94,468	200,001

c.13) Sensitivity analysis for actuarial assumptions

The Company believes that the significant actuarial assumptions with reasonable likelihood of variation due to financial and economic scenarios, which could significantly change the amount of the defined benefit obligation, are the discount rate used to adjust the defined benefit liability to present value and the rate of growth of medical costs.

Sensitivity analysis of the defined benefit liability for scenarios involving a 0.5% increase and a 0.5% decrease in the discount rate used to discount the defined benefit liability to present value is as follows:

F-93

	Post-retirement pension plans	Post-retirement health plans	Total
Defined benefit liability, discounted to present value at current rate	1,861,651	1,050,576	2,912,227
Defined benefit liability, discounted to present value considering a rate increased by 0.5%	1,784,735	977,286	2,762,021
Defined benefit liability, discounted to present value considering a rate decreased by 0.5%	1,944,833	1,132,896	3,077,729

The following is a sensitivity analysis on the defined benefit obligation for scenarios of 1% increase and 1% reduction in the rate of growth of medical costs:

	Post-retirement pension plans	Post-retirement health plans	Total
Defined benefit liability, Projected by the current medical cost growth rate	1,861,651	1,050,576	2,912,227

31)  FINANCIAL INSTRUMENTS AND RISK AND CAPITAL MANAGEMENT

a) Derivative transactions

The derivative financial instruments contracted by the Company are mainly intended to hedge against foreign exchange risk arising from assets and liabilities in foreign currency, risk of inflation on its debentures and leases indexed to the IPCA and against the risk of changes in TJLP of a portion of debt with BNDES. There are no, derivative financial instruments for speculative purposes and possible currency risks are hedged.

F-95

Management understands that the Company's internal controls for its derivatives are adequate to control risks associated with each strategy for the market. Gains/losses obtained or sustained by the Company in relation to its derivatives show that its risk management has been appropriate.

The Company calculates the effectiveness of the derivative contracts to hedge its financial liabilities and cash flows in foreign currency at the beginning of the operation and on an ongoing basis. At December 31, 2017 and 2016, the derivative instruments were effective for the hedged items.

As long as these derivatives contracts qualify for hedge accounting, the hedged item may also be adjusted to fair value, offsetting the result of the derivatives, according to the rules of hedge accounting. This hedge accounting applies both to financial liabilities and probable cash flows in foreign currency.

At December 31, 2017 and 2016, the Company held no embedded derivatives contracts.

Derivatives contracts include specific penalties for breach of contract. Breach of contract provided for in agreements made with financial institutions leads to the early maturity thereof.

a.1) Fair value of derivative financial instruments

The valuation method used to calculate the fair value of financial liabilities (if applicable) and derivative financial instruments was the discounted cash flow method, based on expected settlements or realization of liabilities and assets at market rates prevailing at the balance sheet date.

The fair values of positions in Reais are calculated by projecting future inflows from transactions using B3 yield curves discounting these flows to present value using market DI rates for swaps announced by B3.

The market values of foreign-exchange derivatives were obtained using the market exchange rates in effect at the balance sheet date and projected market rates obtained from the currency's coupon-rate yield curves. The linear convention of 360 calendar days was used to determine coupon rates of positions indexed in foreign currencies, while the exponential convention of 252 business days was used to determine coupon rates for positions indexed to CDI rates.

Consolidated derivatives financial instruments shown below are registered with B3 and classified as swaps, usually, that do not require margin deposits.

The table below shows the breakdown of swaps maturing after December 31, 2017:

	Maturing in

Total	82,403	53,820	1,129	6,402	143,754

For the purposes of preparing its financial statements, the Company adopted the fair value hedge accounting methodology for its foreign currency swaps x CDI, IPCA x CDI, IGPM x CDI and TJLP x CDI for hedging or financial debt. Under this arrangement, both derivatives and hedged risk are recognized at fair value.

The ineffective portion at December 31, 2017 was R$1,289 (R$2,091 at December 31, 2016).

At December 31, 2017 and 2016, the transactions with derivatives generated consolidated negative (net) result of R$41,985 and R$347,870, respectively (Note 26).

a.2) Sensitivity analysis to the Company’s risk variables

The IFRS 7  requires by disclosing sensitivity analyses for each type of market risk that management understands to be significant when originated by financial instruments to which the entity is exposed at the end of each period, including all derivatives financial instrument transactions.

In making the above analysis, each of the transactions with derivative financial instruments was assessed and assumptions included a probable scenario and two others that could adversely impact the Company.

In the probable scenario the assumption is to use, on the maturity dates of each of the transactions, what the market had been showing through B3 yield curves (currencies and interest rates), as well as data available at IBGE, Central Bank, FGV, among others. In the probable scenario, there is no impact on the fair value of the above-mentioned derivatives. However, for scenarios II and III, risk variables were considered to deteriorate by 25% and 50% respectively.

Since the Company only holds derivatives to hedge its foreign-currency assets and liabilities, changing scenarios are tracked by the corresponding hedged items, thus showing that effects are almost non-existent. For these transactions, the Company reported the consolidated net exposure in each of the above-mentioned three scenarios at December 31, 2017.

The assumptions used by the Company for the sensitivity analysis at December 31, 2017 were as follows:

Sensitivity analysis assumptions

F-99

Risk Variable	Probable	25% depreciation	50% depreciation
US$	3.3080	4.1350	4.9620
EUR	3.9676	4.9595	5.9514
JPY	0.0293	0.0367	0.0440
IPCA	2.79%	3.49%	4.19%
IGPM	-0.52%	-0.65%	-0.78%
IGP-DI	-0.27%	-0.34%	-0.41%
UMBND	0.0646	0.0807	0.0969
URTJLP	2.0314	2.5392	3.0470
CDI	6.89%	8.61%	10.34%

For calculation of the net exposure for the sensitivity analysis, all derivatives were considered at market value and hedged items designated for hedge for accounting purposes were also considered at fair value.

The fair values shown in the table above are based on the portfolio position at December 31, 2017, but do not reflect an estimate for realization due to the dynamism of the market, which is constantly monitored by the Company. The use of different assumptions could significantly affect the estimates.

b) Fair value

The Company assessed their financial assets and liabilities in relation to market values using available information and appropriate valuation methodologies. However, both the interpretation of market data and the selection of valuation methods require considerable judgment and reasonable estimates to produce the most adequate realization value. As a result, the estimates shown do not necessarily indicate amounts that could be realized in the current market. The use of different assumptions for the market and/or methodologies may have a material effect on estimated realization values. At December 31, 2017 and 2016, neither the Company not its subsidiaries detected any significant and enduring impairment of their financial instruments.

The fair value of all assets and liabilities are classified within the fair value hierarchy described below, based on the lowest level of information that is significant to the fair value measurement as a whole:

Level 1: quoted market prices (unadjusted) in active markets for identical assets or liabilities;

Level 2: valuation techniques for which significant lower level of information to measure the fair value directly or indirectly observable; and

Level 3: valuation techniques for which the lowest and significant level of information to measure the fair value is not available.

During years ended December 31, 2017 and 2016, there were no transfers between fair value measurements of level 3 and level 1 and 2.

The following table show the composition of financial assets and liabilities at December 31, 2017 and 2016.

c) Capital management

The purpose of the Company's capital management is to ensure maintenance of a high credit rating before institutions and an optimal capital ratio in order to support the Company's business and maximize shareholder value.

The Company manages its capital structure by making adjustments and adapting to current economic conditions. For this purpose, the Company may pay dividends, raise new loans, issue debentures and contract derivatives. For the year ended December 31, 2017, there were no changes in capital structure objectives, policies or processes.

In its net debt structure, the Company includes balances referring to loans, financing, debentures, finance leasing, contingent consideration and transactions with derivatives, less cash and cash equivalents, short-term investments to secure BNB financing and guarantor of the contingent consideration liability.

The Company’s ratio of consolidated debt to shareholders’ equity consists of the following:

F-101

	12.31.17	12.31.16
Cash and cash equivalents	4,050,338	5,105,110
Loans, financing, debentures, financial lease and contingent consideration	(8,461,841)	(9,224,074)
Derivative transactions, net	143,754	28,377
Short-term investment pledged as collateral	11,722	10,773
Asset guarantor of contingent consideration	446,144	414,733
Net debt	3,809,883	3,665,081
Net equity	69,461,358	69,244,419
Net debt-to-equity ratio	5.48%	5.29%

d) Risk management policy

The Company is exposed to several market risks as a result of its commercial operations, debts contracted to finance its activities and debt-related financial instruments.

d.1) Currency Risk

There is risk arising from the possibility that the Company may incur losses due to fluctuating exchange rates, which add to costs arising from loans denominated in foreign currencies.

At December 31, 2017, 2.7% of financial debt was foreign-currency denominated (14.0% at December 31, 2016). The Company enters into derivative transactions (currency hedge) with financial institutions to hedge against exchange rate variation affecting its total indebtedness in foreign currency (R$225,254 and R$1,287,864 at 31 December 2017 and 2016, respectively). Its total debt on these dates was covered by asset positions in currency-exchange hedge transactions with CDI-rate swaps.

There is also foreign exchange risk for non-financial assets and liabilities denominated in foreign currencies, which may generate a smaller amount receivable or larger amount payable depending on the exchange rate in the period.

Hedging transactions were engaged to minimize the risks associated with exchange-rate variation of non-financial assets and liabilities in foreign currencies. This balance is subject to daily changes due to the dynamics of the business. However, the Company intends to cover the net balance of these rights and obligations (US$16,953 thousand receivableand €17,535 thousand payable by December 31, 2017 and US$17,293 thousand receivableand €5,695 thousand payable by December 31, 2016) to mitigate its foreign exchange risks.

d.2) Interest and Inflation Risk

This risk arises because the Company may incur losses in the event of an unfavorable change in the domestic interest rate, which may adversely affect financial expenses resulting from the portion of debentures referenced to the CDI and liability positions in derivatives (currency hedge, IPCA and TJLP) pegged to floating interest rates (CDI).

The debt with BNDES is indexed to the Long-Term Interest Rate (TJLP) which is set on a quarterly basis by the National Monetary Council. During the year 2016 and for the quarter ended March 30, 2017, the TJLP was 7.5%. In the third quarter of 2017, the TJLP remained at 7.0%, until the end of the year.

Inflation risk arises from the Minas Comunica debentures of the 1st issue, which are tied to the IPCA and thus may adversely affect financial expenses in the event of an unfavorable change in this index.

F-102

To reduce exposure to the variable interest rate (CDI), the Company invested their cash equivalents of R$3,932,539 at December 31, 2017 (R$4,906,741 at December 31, 2016), mostly in short-term CDI-based financial investments (Bank Deposit Certificates). The carrying amounts of these instruments approach their fair values, since they may be redeemed in short term.

d.3) Liquidity Risk

Liquidity risk is the possibility of the Company not holding sufficient funds to meet their commitments due to different currencies and dates of realization of rights and settlement of obligations.

The Company structure the maturity dates of non-derivative financial contracts, as shown in Note 20, and their respective derivatives, as shown in the schedule of payments disclosed in this note, to avoid affecting their liquidity.

The Company cash flow and liquidity and those of its subsidiaries are managed on a daily basis by the departments in charge to ensure that operating cash flows and prior funding, when necessary, will be sufficient to meet their schedule of commitments in order to avoid liquidity risk.

Below, we summarize the maturity profile of our consolidated financial liabilities as set forth in loan agreements:

At 12.31.17	Less than one year	From 1 to 2 years	From 2 to 5 years	Over 5 years	Total
Trade accounts payable (Note 15)	7,447,100	-	-	-	7,447,100

Total	12,457,937	2,486,807	1,404,486	742,613	17,091,843

d.4) Credit Risk

The risk arises from the possibility of the Company incurring losses due to difficulty in receiving amounts billed to their customers and sales of prepaid handsets and cards that have been pre-activated for the distribution network.

The credit risk on accounts receivable is diversified and mitigated by strict control of the customer base. The Company constantly monitors the level of accounts receivable from postpaid services, and limits bad-debt risk by cutting off access to telephone lines if bills are past due. The mobile customer base predominantly uses the prepaid system, which requires purchase of credits beforehand and therefore does not pose credit risk. Exceptions are made for emergency services that must be maintained for security or national defense reasons.

Credit risk on sales of pre-activated prepaid handsets and cards is managed by a conservative policy for granting credit, using modern credit scoring methods, analyzing financial statements and consultations to commercial databases, in addition to requesting guarantees.

F-103

The Company is also subject to credit risk arising from their investments, letters of guarantee received as collateral for certain transactions and receivables from derivative transactions. The Company control the credit limits granted to each counterpart and diversify this exposure across first tier financial institutions as per current credit policies of financial counterparties.

d.5) Social and Environmental Risks

Our operations and properties are subject to various environmental laws and regulations that, among others, govern environmental licenses and records, protection of fauna and flora, air emissions, waste management and remediation of contaminated sites. If we fail to meet present and future requirements, or to identify and manage new or existing contamination, we will incur in significant costs, which include cleaning costs, damages, compensation, fines, activities suspension and other penalties, investments to improve our facilities or change our processes, or interruption of operations. The identification of environmental conditions not currently identified, more stringent inspections by regulatory agencies, the entry into force of more stringent laws and regulations or other unanticipated events may occur and, ultimately, result in significant environmental liabilities and their costs. The occurrence of any of the above factors could have a material adverse effect on our business, results of operations and financial position. According to Article 75 of Law No. 9605 of 1998, the maximum fine per breach of environmental law is R$50,000.

From the social point of view, we are exposed to contingent liabilities due to the fact that our structure foresees the hiring of outsourced service providers. These potential liabilities may involve labor claims by service providers who could eventually be treated as direct employees, which would generate requests for links and joint liability in overtime claims and occupational accidents, among others. If we obtain an unfavorable decision in relation to a significant portion of these contingencies that have not yet been provisioned, our financial and equity situation and the results of our operations may be affected.

d.6) Insurance Coverage

The policy of the Company, as well as the Telefónica Group, includes contracting insurance coverage for all assets and liabilities involving significant and high-risk amounts, based on management's judgment and following Telefónica corporate program guidelines.

d.7) Other Risks

The Company is required to comply with Brazilian anti-corruption laws and regulations, as well as laws and regulations on the same subject in jurisdictions where it has its securities traded. In particular, the Company is subject, in Brazil, to the Law nº 12.846/2013 and, in the United States, to the U.S. Foreign Corrupt Practices Act of 1977.

Although the Company has internal policies and procedures designed to ensure compliance with the aforementioned anti-corruption laws and regulations, there can be no assurance that such policies and procedures will be sufficient or that the Company’s employees, directors, officers, partners, agents and service providers will not take actions in violation of the Company’s policies and procedures (or otherwise in violation of the relevant anti-corruption laws and regulations) for which the Company or they may be ultimately held responsible. Violations of anti-corruption laws and regulations could lead to financial penalties, damage to the Company’s reputation or other legal consequences that could have a material adverse effect on the Company’s business, results of operationsand financial condition.

In connection with the above-mentioned policies, the Company is currently conducting an internal investigation - which is part of a broader investigation being conducted by the controlling shareholder of the Company (Telefónica, S.A.) - regarding possible violations of the abovementioned laws and regulations.  The Company is in contact with governmental authorities about this matter and intends to cooperate with those authorities as the investigation continues.  It is not possible at this time to predict the scope or duration of this matter or its likely outcome.
