Presentation of Financial and Other Information

We present our consolidated financial statements in accordance with International Financial Reporting Standards, or “IFRS,” as issued by the International Accounting Standards Board, or “IASB,” for both Securities and Exchange Commission, or “SEC,” and the Brazilian Securities Commission (Comissão de Valores Mobiliários), or “CVM,” filings.

The consolidated financial statements are presented in Brazilian reais. However, the functional currency of Cosan Limited is the U.S. dollar. The Brazilian real is the currency of the primary economic environment in which Cosan S.A. Indústria e Comércio, or “Cosan” or “Cosan S.A.,” Cosan Logística S.A., or “Cosan Logística,” and their respective subsidiaries and jointly-controlled entities, located in Brazil, operate and generate and expend cash. The functional currency for the subsidiaries located outside Brazil is the U.S. dollar or the British pound. Cosan Limited, Cosan S.A., Cosan Logística and its subsidiaries are collectively referred to as the “Company.”

We have presented our consolidated financial statements for the years ended December 31, 2017, 2016 and 2015, in accordance with IFRS as issued by the IASB. Our consolidated financial statements as of December 31, 2017, 2016 and 2015 and for the years then ended have been audited by KPMG Auditores Independentes, or “KPMG.” KPMG is an independent registered public accounting firm, whose report is included herein.

On June 1, 2011, we and Shell Brazil Holdings B.V., or “Shell,” formed two joint ventures, or the “Joint Venture,” for a combined 50/50 investment, under the names Raízen Combustíveis S.A., or “Raízen Combustíveis” and Raízen Energia e Participações S.A. (currently Raízen Energia S.A.), or “Raízen Energia,” collectively referred to as “Raízen.” Our management evaluates the results of Raízen Energia and Raízen Combustíveis on the same basis as they are evaluated by the management of Raízen, which is on a 100% basis. Accordingly, unless the context requires otherwise, operational information pertaining to Raízen Energia and Raízen Combustíveis included in this annual report refers to 100% of the operations of these businesses. Upon the application of IFRS 11- Joint Arrangements, or “IFRS 11,” the Company retrospectively changed the accounting for its investments in Raízen Combustíveis and Raízen Energia, classifying them as investments in joint ventures. As such, for the nine-month period ended December 31, 2013, the Company accounted for these joint ventures under the equity method as opposed to the proportional consolidation method previously applied until March 31, 2013, and the accounting for the joint ventures for the fiscal year ended March 31, 2013 has been restated for the impacts of retrospectively adopting IFRS 11. As disclosed in “Item 5. Operating and Financial Review and Prospects,” following the adoption of IFRS 11, starting in April 2013 Cosan no longer proportionally consolidates Raízen Energia and Raízen Combustíveis in its consolidated statement of financial position, statement of profit or loss and comprehensive income and statement of cash flows, and the results of these investments have been presented using the equity method of accounting in accordance with IAS 28R—“Investments in Associates and Joint Ventures.” For further details, see note 14 to our financial statements.

During 2014, the Company identified an immaterial error in the calculation of diluted earnings per share impacting the nine-month period ended December 31, 2013 and the fiscal year ended March 31, 2013. The error consisted of a mathematically inaccurate calculation of the monetary effect of dilution on the profits attributable to shareholders of the parent. The revisions to correct the error in the applicable fiscal years are reflected in the financial information herein and will be reflected in future filings containing such information.

On April 1, 2015, Cosan, through its subsidiary Rumo Logística Operadora Multimodal S.A. or “Rumo Logística,” acquired 100% of the common shares of ALL – América Latina Logística S.A., or “ALL.” Accordingly, we began consolidating ALL’s results within our own as from that date.

On September 30, 2016, Cosan S.A. entered into a Share Purchase Agreement with Mansilla Participações Ltda. (a vehicle of TIAA Teachers Insurance and Annuity Association of America), another shareholder in Radar Propriedades Agrícolas S.A. and Radar II Propriedades Agrícolas S.A., or “Radar and Radar II,” through which Cosan S.A. sold part of its shares in Radar and Radar II for an amount of R$1,053.8 million. The consideration was received on November 4, 2016. As a result of this transaction, Cosan S.A. reduced its equity interest in Radar and Radar II from 37.7% to 3.0%. Cosan S.A. retains significant influence over Radar and Radar II through a shareholders’ agreement as described in “Item 7. Major Shareholders and Related Party Transactions.” The criteria used to measure the remaining stake of the investment was the equity method, in accordance with IAS 28, although it is not consolidated due to the inhibition of Cosan’s decision-making power defined on the shareholders agreement. The comparative consolidated statement of profit or loss and statements of cash flows have been restated to show the discontinued operation separately from continuing operations.

iii

On October 8, 2016, ALL – América Latina Logística S.A. changed its corporate name to Rumo S.A. or “Rumo.” Subsequently, on December 31, 2016, Rumo Logística was merged into its wholly-owned subsidiary Rumo, as a result of which Rumo S.A. is the successor entity to Rumo Logística.

In November 2016, Cosan S.A. and Shell executed amendments to certain agreements between them to remove the fixed date call options over Raízen Energia and Raízen Combustíveis shares exercisable in 2021 and 2026, and replace them with certain call and put options exercisable by Shell or Cosan S.A. upon the occurrence of certain events including, among others: (i) fundamental breaches of the obligations provided for in the agreements governing the Joint Venture; (ii) breach of anticorruption laws, (iii) insolvency or bankruptcy of a party, (iv) change of control, and (v) in the event of the death or disability of Cosan S.A.’s current Chairman, Mr. Rubens Ometto Silveira Mello. Moreover, Cosan S.A. and Shell agreed to renew the existing lock-up period for five years from the date of the execution of the amendment, following which the parties may sell their shares in each of Raízen Energia and Raízen Combustíveis subject to compliance with certain preemption rights in each other’s favor.

In 2016, amendments to IAS 16 and IAS 41 changed the accounting requirements for biological assets that fall within the definition of “bearer plants.” These amendments substantially impact Raízen Energia, and the following line items: “Investments in Joint Ventures” in our statement of financial position and “Equity in Earnings of Joint Ventures” in our statement statements of profit or loss.

Furthermore, during 2016, Cosan identified an immaterial error related to the recognition of tax installment liabilities, related to federal taxes other than income tax, referring to 2011. Cosan has determined that it was appropriate to revise its financial statements for the years ended December 31, 2016, 2015 and 2014. The revisions to correct the error in the applicable fiscal years are reflected in the financial information herein and will be reflected in future filings containing such information.

On February 23, 2017, TPG VI Fundo de Investimento em Participações, or “TPG VI,” a shareholder of Rumo S.A., or “Rumo,” exercised its right to exchange 11,479,987 shares issued by Rumo for shares issued by Cosan S.A. pursuant to the shareholders’ agreement entered into in 2010 between Cosan Logística, TPG VI, GIF, Cosan S.A. and the Company. Cosan S.A. and GIF agreed to settle financially the stock replacement obligation through of payment of R$275.8 million and the shares received were valued at fair value in the amount of R$97.9 million and recorded as capital reserve.

On December 12, 2017, we exercised a put option with Shell relating to shares in Companhia de Gás de São Paulo – COMGÁS, or “Comgás,” and bought a total of 21,805,645 shares, which represents 16.77% of Comgás’s share capital for R$1,042 million. As part of the payment, we delivered to Shell 17,187,937 common shares issued by Cosan S.A., representing 4.21% of its capital stock, and also made a cash payment of R$208.7 million. Additionally, was recognized accounts payable referring to the second installment to be settled within one year after the closing of the transaction in the amount of R$208.7 million (plus interest accruing at rate of 3% per year). As a result, Shell ceased to be a shareholder in Comgás.

On December 22, 2017, Cosan S.A. entered into a definitive agreement with Jus Capital Gestão de Recursos Ltda. and Farallon Latin America Investimentos Ltda., for the purchase and sale of credit rights arising from severance claims filed against the Brazilian federal government, which was required to pay compensation for material damages resulting from the fixing of sugar and alcohol prices below their cost of production, in a total amount of R$1,340 million. In addition to the acquisition price, Cosan S.A. will be entitled to receive certain additional payments which are contingent upon the purchaser’s actual receipts from the receivables.

Forward-Looking Statements

This annual report contains estimates and forward-looking statements, mainly under “Item 3. Key Information—D. Risk Factors,” “Item 4. Information on the Company—B. Business Overview” and “Item 5. Operating and Financial Review and Prospects.” Some of the matters discussed concerning our business and financial performance include estimates and forward-looking statements.

iv

Our estimates and forward-looking statements are mainly based on our current expectations and estimates on projections of future events and trends, which affect or may affect our businesses and results of operations. Although we believe that these estimates and forward-looking statements are based upon reasonable assumptions, they are subject to several risks and uncertainties and are made in light of information currently available to us. Our estimates and forward-looking statements may be influenced by the following factors, among others:

• general economic, political, demographic and business conditions in Brazil and in the world and the cyclicality affecting our selling prices;

• the effects of global financial and economic crises in Brazil;

• our ability to implement our expansion strategy in other regions of Brazil and international markets through organic growth, acquisitions or Joint Ventures;

• our ability to successfully compete in all segments and geographical markets where we currently conduct business or may conduct businesses in the future;

• competitive developments in the segments in which we operate;

• our ability to implement our capital expenditure plan, including our ability to arrange financing when required and on reasonable terms;

• government intervention resulting in changes in the economy, taxes and tariffs affecting the markets in which we operate;

• price of natural gas, ethanol and other fuels, as well as sugar;

• equipment failure and service interruptions;

• our ability to compete and conduct our businesses in the future;

• adverse weather conditions;

• changes in customer demand;

v

The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect” and similar words are intended to identify estimates and forward-looking statements. Estimates and forward-looking statements speak only as of the date they were made, and we undertake no obligation to update or to review any estimate and/or forward-looking statement because of new information, future events or other factors. Estimates and forward-looking statements involve risks and uncertainties and are not guarantees of future performance. Our future results may differ materially from those expressed in these estimates and forward-looking statements. In light of the risks and uncertainties described above, the estimates and forward-looking statements discussed in this annual report might not occur and our future results and our performance may differ materially from those expressed in these forward-looking statements due to but not limited to, the factors mentioned above. Because of these uncertainties, you should not make any investment decision based on these estimates and forward-looking statements.

Fiscal Year

On July 31, 2013, we changed our fiscal year from March 31 to December 31. This change was driven by the evolution in our investment portfolio, in which businesses that do not use the harvest year as their year-end (March 31) have become more significant. References in this annual report to “transition period 2013” relate to the nine months ended on December 31, 2013. For comparison purposes, we have also included in this annual report our unaudited condensed consolidated income statement for the twelve-month period ended December 31, 2013. References in this annual report to “fiscal year 2013” or prior fiscal years relate to the fiscal year ended on March 31 of that calendar year. However, for purposes of calculating income and social contribution taxes in accordance with Brazilian law, the applicable year ends on December 31.

For comparison purposes, we have compiled and included in this annual report certain financial information extracted from our unaudited condensed consolidated income statement for the twelve-month period ended December 31, 2013, to provide a meaningful point of comparison with the fiscal year ended December 31, 2014. Our unaudited condensed consolidated income statement for the twelve-month period ended December 31, 2013 was prepared by combining the audited condensed consolidated income statement for the nine-month period ended December 31, 2013 with the unaudited condensed consolidated income statement for the three-month period ended March 31, 2013.

Market Data

We obtained market and competitive position data, including market forecasts, used throughout this annual report from market research, publicly available information and industry publications, as well as internal surveys. We include data from reports prepared by LMC International Ltd., the Central Bank of Brazil (Banco Central do Brasil), or the “Brazilian Central Bank,” the Sugarcane Agroindustry Association of the State of São Paulo (União da Agroindústria Canavieira de São Paulo), or “UNICA,” the Ministry of Agriculture, Livestock, and Supply (Ministério da Agricultura, Pecuária e Abastecimento), or “MAPA,” the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística), or “IBGE,” the National Traffic Agency (Departamento Nacional de Trânsito—DENATRAN), the Brazilian Association of Vehicle Manufactures (Associação Nacional dos Fabricantes de Veículos Automotores—ANFAVEA),” Datagro Publicações Ltda., F.O.

In the fiscal year ended March 31, 2012 our sugar and ethanol assets were contributed to the formation of the joint ventures, Raízen Energia and Raízen Combustíveis, and the revenues from such operations ceased to be consolidated into the results of operations, as these joint ventures are accounted for under the equity method, in accordance with IFRS 11.

(1) Net debt consists of current and non-current debt, net of cash and cash equivalents, marketable securities and derivatives on debt recorded in our consolidated financial statements as other non-current assets. Net debt is a non-GAAP measure.

(2) Working capital consists of total current assets less total current liabilities.

(3) Starting from 2015 the reported volumes are based on a methodology developed by Sindicom (Sindicato Nacional das Empresas Distribuidoras de Combustíveis e de Lubrificantes), an association of fuel distributors, which excludes volumes sold to other distributors.

The information in the table below presents a reconciliation of Net debt, a non-GAAP financial measure, the most directly comparable IFRS financial measure. Our calculation of these Net debt may differ from the calculation of similarly titled measures used by other companies. Our management believes that disclosure of Net Debt is useful to potential investors as it helps to give them a clearer understanding of our financial liquidity. Net Debt is also used to calculate certain leverage ratios. However, Net Debt is not a measure under IFRS and should not be considered as a substitute for measures of indebtedness determined in accordance with IFRS.

Exchange Rates

The Brazilian foreign exchange system allows the purchase and sale of foreign currency and the international transfer of reais by any person or legal entity, regardless of the amount, subject to certain regulatory procedures.

Since 1999, the Brazilian Central Bank has allowed the real/U.S. dollar exchange rate to float freely, which resulted in increasing exchange rate volatility. Until early 2003, the real declined against the U.S. dollar. Between 2004 and 2008, the real strengthened against the U.S. dollar, except in the most severe periods of the global economic crisis. Given the recent turmoil in international markets and the current Brazilian macroeconomic outlook, the real depreciated against the U.S. dollar from mid-2011 to early 2016. Beginning in early 2016 through the end of 2016, the real appreciated against the U.S. dollar, primarily as a result of Brazil’s changing political conditions. In 2017, the real depreciated 1.5% against the U.S. dollar. In 2018, to April 25, 2018, the real depreciated 5.9% against the U.S. dollar. In the past, the Brazilian Central Bank has intervened occasionally to control high volatility in the foreign exchange rates. We cannot predict whether the Brazilian Central Bank or the Brazilian government will continue to permit the real to float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. In the future, the real may fluctuate substantially against the U.S. dollar.

Furthermore, Brazilian law provides that, whenever there is a serious imbalance in Brazil’s balance of payments or there are compelling reasons to foresee a serious imbalance, temporary restrictions may be imposed on remittances of foreign capital abroad. Any such restrictions on remittances of foreign capital abroad may limit our ability to receive dividends from our subsidiaries Cosan S.A. and Cosan Logística S.A. We cannot assure you that such measures will not be taken by the Brazilian government in the future. Exchange rate fluctuation will affect the U.S. dollar equivalent of the market price of our Brazilian Depositary Receipts, or “BDRs,” on B3, as well as the U.S. dollar value of any distributions we receive from our subsidiaries Cosan S.A. and Cosan Logística S.A., which will be made in reais. See “—D. Risk Factors—Risks Related to Brazil.”

D. Risk Factors

This section is intended to be a summary of more detailed discussion contained elsewhere in this annual report. Our business, financial condition or results of operations could be materially and adversely affected by any of the risks and uncertainties described below. As a result, the market price of our shares and the BDRs could decline, and you could lose all or part of your investment. Additional risks not presently known to us, or that we currently deem immaterial, may also impair our financial condition and business operations.

Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate

We may not be successful in reducing operating costs and increasing operating efficiencies.

As part of our strategy, we continue to seek to reduce operating costs and increase operating efficiencies to improve our future financial performance. We may not be able to achieve the cost savings that we expect to achieve as a result of several factors, including increases in the price of our raw materials and other cost inputs. Given the highly competitive markets in which we operate, with prices often being defined based on global supply and demand, it is highly likely that we will not pass on material cost increases, which would materially and adversely affect our financial performance.

The expansion of our business through acquisitions and strategic alliances creates risks that may reduce the benefits we anticipate from these transactions.

We have grown substantially through acquisitions. We may continue to expand by acquiring or investing, directly or indirectly, from time to time, in businesses considered suitable by our management that are consistent with our values and that are expected to generate positive returns. We may also enter into strategic alliances to increase our competitiveness. However, our management is unable to predict whether or when any prospective acquisitions or strategic alliances will occur, or the likelihood of any particular transaction being completed on favorable terms and conditions. Our ability to continue to expand our business through acquisitions or alliances depends on many factors, including our ability to identify acquisitions or access capital markets on acceptable terms. Even if we are able to identify acquisition targets and obtain the necessary financing to make these acquisitions, we could financially overextend ourselves.

Acquisitions, especially involving sizeable enterprises, may present financial, managerial and operational challenges, including diversion of management attention from existing business and difficulties in integrating operations and personnel. Any failure by us to integrate new businesses or manage any new alliances successfully could adversely affect our business and financial performance. Some of our major competitors may be pursuing growth through acquisitions and alliances, which may reduce the likelihood that we will be successful in completing acquisitions and alliances. In addition, any major acquisition we consider may be subject to antitrust and other regulatory approvals. We may not be successful in obtaining required approvals on a timely basis or at all.

Acquisitions also pose the risk that we may be exposed to successor liability relating to prior actions involving an acquired company, or contingent liabilities incurred before the acquisition. Due diligence conducted in connection with an acquisition, and any contractual guarantees or indemnities that we receive from sellers of acquired companies, may not be sufficient to protect us from, or compensate us for, actual liabilities. A material liability associated with an acquisition, such as labor or environmental liability, could adversely affect our reputation and financial performance and reduce the benefits of the acquisition.

We may engage in hedging transactions, which involve risks that can harm our financial performance.

We are exposed to market risks arising from the conduct of our business activities—in particular, market risks arising from changes in commodity prices, exchange rates or interest rates. In an attempt to minimize the effects of the volatility of sugar prices and exchange rates on our cash flows and results of operations, we engage in hedging transactions involving commodities and exchange rate futures, options, forwards and swaps. We also engage in interest rate-related hedging transactions from time to time. Hedging transactions expose us to the risk of financial loss in situations where the counterparty to the hedging contract defaults on its contract or there is a change in the expected differential between the underlying price in the hedging agreement and the actual price of commodities or exchange rate. We may incur significant hedging-related losses in the future. We hedge against market price fluctuations by fixing the prices of our sugar export volumes and exchange rates. Since we record derivatives at fair value, to the extent that the market prices of our products exceed the fixed price under our hedging policy, our results will be lower than they would have been if we had not engaged in such transactions as a result of the related non-cash derivative expenses. As a result, our financial performance would be adversely affected during periods in which commodities prices increase. Alternatively, we may choose not to engage in hedging transactions in the future, which could have a material adverse effect on our financial performance during periods in which commodities prices decrease.

The costs of complying with current and future legislation related to environmental protection, health and safety, and the contingencies arising from environmental damage and affected third parties may have a material adverse effect on our business, results of operations as well as on our financial condition.

The judicial and administrative penalties, including criminal sanctions, imposed on those who fail to comply with environmental laws are applied irrespective of whether there exists any obligation on such persons to repair any damage caused to the environment. Furthermore, the obligation to repair environmental damage caused may be imposed upon all parties deemed to be involved in such damage, whether directly or indirectly and regardless of such parties’ actual culpability. As a result, when we hire third parties to perform work for us, such as the disposal of waste or vegetation suppression, we are not exempt from liability for any environmental damage caused by these independent contractors. In addition, we can be held liable for any and all consequences arising from the exposure of people to harmful substances or other environmental damage. The costs of complying with current and future legislation related to environmental protection, health and safety, and the contingencies arising from environmental damage and affected third parties may have a material adverse effect on our business, results of operations as well as on our financial condition.

Technological advances could affect demand for our products or require substantial capital expenditures for us to remain competitive.

The development and implementation of new technologies may result in a significant reduction in the costs of sugar and ethanol production. We cannot predict when new technologies may become available, the rate of acceptance of new technologies by our competitors or the costs associated with such new technologies. Advances in the development of alternatives to sugar and ethanol also could significantly reduce demand or eliminate the need for sugar and ethanol as a fuel oxygenate. Any advances in technology which require significant capital expenditures to remain competitive or which otherwise reduce demand for sugar and ethanol will have a material adverse effect on our business and financial performance.

We may be unable to implement our growth strategy successfully.

Our future growth and financial performance will depend, in part, on the successful implementation of our business strategy, including: (a) our ability to attract new clients or increase volume from existing clients in specific markets and locations, (b) our capacity to finance investments (through indebtedness or otherwise), (c) our ability to increase our operational capacity and expand our current capacity to supply to new markets and (d) maintain and renew our existing concessions. We cannot assure you that we will be able to achieve these objectives successfully or at all. Our failure to achieve any of these objectives as a result of competitive difficulties, cost or restrictions on our ability to invest may limit our ability to implement our growth strategy successfully. We may need to incur additional indebtedness in order to finance new investments to implement our growth strategy. Unfavorable economic conditions in Brazil and in the global credit markets, such as high interest rates on new loans, reduced liquidity or reduced interest of financial institutions in granting loans, may limit our access to new credit. Furthermore, failure to achieve our expected growth may have a material adverse effect on our business, financial conditions, results of operations and our ability to repay our debt obligations.

We may face conflicts of interest in transactions with related parties.

We engage in business and financial transactions with our controlling shareholder and other shareholders that may create conflicts of interest between our Company and these shareholders. Commercial and financial transactions between our affiliates and us, even if entered into on an arm’s-length basis, create the potential for, or could result in, conflicts of interests.

Lack of service providers for our expansion projects could adversely affect our business.

We are engaged in a number of expansion projects within our concession area that will require a significant number of service providers, which may not be available. Consequently, if we are unable to contract the necessary services due to service industry shortages or a lack of providers with the technical ability to provide the services we require, this could have an adverse effect on our expansion projects or lead to delays in the execution of our expansion projects as new service providers go through an approval process and develop the technical qualification to commence operations. Any delay or failure to commence or continue our expansion projects within our projected timeframe or budget could have a material adverse effect on our business, financial condition and results of operations.

We depend on our information technology systems, and any failure of these systems could adversely affect our business.

We depend on information technology systems for significant elements of our operations, including the storage of data and retrieval of critical business information. Our information technology systems are vulnerable to damage from a variety of sources, including network failures, malicious human acts, and natural disasters. Moreover, despite network security and back-up measures, some of our servers are potentially vulnerable to physical or electronic break-ins, computer viruses, and similar disruptive problems. Failures or significant disruptions to our information technology systems or those used by our third-party service providers could prevent us from conducting our general business operations. Any disruption or loss of information technology systems on which critical aspects of our operations depend could have an adverse effect on our business, results of operations, and financial condition. Further, we store highly confidential information on our information technology systems, including information related to our products. If our servers or the servers of the third party on which our data is stored are attacked by a physical or electronic break-in, computer virus or other malicious human action, our confidential information could be stolen or destroyed. Any security breach involving the misappropriation, loss or other unauthorized disclosure or use of confidential information of our suppliers, customers, or others, whether by us or a third party, could (1) subject us to civil and criminal penalties, (2) have a negative impact on our reputation, or (3) expose us to liability to our suppliers, customers, other third parties or government authorities. Any of these developments could have an adverse impact on our business, financial condition and results of operations.

We could be the target of attempted cyber threats in the future and they could adversely affect our business.

We may be subject to potential fraud and theft by cyber criminals, who are becoming increasingly sophisticated, seeking to obtain unauthorized access to or exploit weaknesses that may exist in our systems. While we continuously monitor and develop our information technology networks and infrastructure to prevent, detect, address and mitigate the risk of unauthorized access, misuse, computer viruses and other events that could have a security impact on us to ensure that we are protected, to the extent possible, against cyber risks and security breaches, such measures may not be effective in protecting us against cyber-attacks and other related breaches of our information technology systems. Any disruption or loss of information technology systems, on which critical aspects of our operations depend, could have an adverse effect on our business, results of operations and financial condition.

Further, we store highly confidential information on our information technology systems, including information related to our products. If our servers or the servers of the third parties on which our data is stored are the subject of a physical or electronic break-in, computer virus or other cyber risks, our confidential information could be stolen or destroyed. Any security breach involving the misappropriation, loss or other unauthorized disclosure or use of confidential information of our suppliers, customers, or others, whether by us or a third party, could (1) subject us to civil and criminal penalties, (2) have a negative impact on our reputation or (3) expose us to liability to our suppliers, customers, other third parties or government authorities.

Any of these developments could have an adverse impact on our business, financial condition and results of operations.

We are subject to the application of data protection law penalties in the event of non-compliance with the terms and conditions of certain new European regulations.

The European Union has recently adopted a comprehensive overhaul of its data protection regime from the current national legislative approach to a single European Economic Area Privacy Regulation, the General Data Protection Regulation, or “GDPR,” which comes into effect in 2018, and some aspects of our operations or business are subject to this privacy and data protection regulation. The proposed EU data protection regime extends the scope of the EU data protection law to all foreign companies processing data of EU residents and imposes heightened requirements on controllers that engage in activities that are within scope of this regulation. It imposes a strict data protection compliance regime with severe penalties of up to the greater of 4% of worldwide turnover or €20 million and, in the case of a data breach, the organization may be required to notify potentially affected individuals. We are currently evaluating the rule and its requirements. Implementation of the GDPR could require changes to certain of our business practices, thereby increasing our costs and noncompliance with its terms could adversely affect our business.

Our performance depends on favorable labor relations with our employees and our compliance with labor laws. Any deterioration of those relations or increase in labor costs could adversely affect our business.

All of our employees are represented by labor unions. Our relationships with these organizations are governed by labor agreements or collective bargaining agreements which we negotiate with labor unions. Upon the expiry of such agreements, we are required to renegotiate new agreements with the applicable labor union. As part of these renegotiations, new terms and conditions may be established. In certain cases, these agreements may not be renewed, which could lead to strikes and/or stoppages in our activities and have an adverse impact on our business, financial condition and results of operations.

We operate in industries in which the supply, demand and the market price for our products are cyclical and are affected by general economic conditions in Brazil and globally.

The ethanol and sugar industries, globally and in Brazil, have historically been cyclical and sensitive to domestic and international changes in supply and demand. Our sugar production depends on the volume and sucrose content of the sugarcane that we cultivate or is provided to us by farmers located near our plants. Crop yields and sucrose content of the sugarcane mainly depend on weather conditions, such as rainfall and temperature, which may vary and may be influenced by global climate change.

Weather conditions have caused volatility in the ethanol and sugar sectors and, consequently, in our operational results by causing crop failures or reduced harvests. Floods, droughts and frosts, which can be influenced by global climate change, may affect the supply and prices of the agricultural commodities we sell and use in our business. Future climate conditions may reduce the quantity of sugar and sugarcane that we can obtain in a given crop or the sucrose content of the sugarcane. In addition, our production of sugar and ethanol is contingent on our ability to incur capital expenditures to renew sugarcane crops.

Historically, the international sugar market has experienced periods of limited supply, causing sugar prices and industry profit margins to increase, followed by an expansion in the industry that results in oversupply, causing declines in sugar prices and industry profit margins. In addition, fluctuations in prices for ethanol or sugar may occur, for various other reasons, including factors beyond our control, such as:

• reduced demand for motor vehicles powered by internal combustion engines;

• fluctuations in gasoline prices;

• variances in the production capacities of our competitors; and

• the availability of substitute goods for the ethanol and sugar products we produce.

The prices we are able to obtain for sugar depend, in large part, on prevailing market conditions. These market conditions, both in Brazil and internationally, are beyond our control. The wholesale price of sugar has a significant impact on our profits. Like other agricultural commodities, sugar is subject to price fluctuations resulting from weather, natural disasters, harvest levels, agricultural investments, government policies and programs for the agricultural sector, domestic and foreign trade policies, shifts in supply and demand, increasing purchasing power, global production of similar or competing products, and other factors beyond our control. In addition, a significant portion of the total worldwide sugar production is traded on exchanges and thus is subject to speculation, which could affect the price of sugar and our results of operations.

The price of sugar, in particular, is also affected by producers’ compliance with sugar export requirements and the resulting effects on domestic supply. As a consequence, sugar prices have been subject to high historical volatility. Competition from alternative sweeteners, including saccharine and high fructose corn syrup, known as “HFCS,” changes in Brazilian or international agricultural or trade policies or developments relating to international trade, including those under the World Trade Organization, are factors that can directly or indirectly result in lower domestic or global sugar prices. Any prolonged or significant decrease in sugar prices could have a material adverse effect on our business and financial performance.

Ethanol is marketed as a fuel additive to reduce vehicle emissions from gasoline, as an enhancer to improve the octane rating of gasoline with which it is blended or as a substitute fuel for gasoline. As a result, ethanol prices are influenced by the supply of and demand for gasoline, and our business and financial performance may be materially adversely affected by fluctuations in the demand for and/or price of gasoline. The increase in the production and sale of flex fuel vehicles (hybrid vehicles, that run with ethanol or gasoline or both combined in any proportion) has resulted, in part, from lower taxation, since 2002, of such vehicles compared to gasoline only cars. This favorable tax treatment may be eliminated and the production of flex fuel vehicles may decrease, which could adversely affect demand for ethanol.

If we are unable to maintain sales at generally prevailing market prices for sugar and ethanol in Brazil and internationally, or if we are unable to export sufficient quantities of ethanol and sugar to assure an appropriate domestic market balance, our ethanol and sugar business as well as our cash flow may be adversely affected.

Ethanol prices are directly influenced by sugar and gasoline prices, so that a decline in those prices will adversely affect both our ethanol and sugar businesses.

The price of ethanol generally is closely associated with the price of sugar and is increasingly becoming correlated to gasoline prices in local market. A vast majority of ethanol in Brazil is produced at sugarcane mills that produce both ethanol and sugar. Because sugarcane millers are able to alter their product mix in response to the relative prices of ethanol and sugar, this results in the prices of both products being directly correlated, and the correlation between them may increase over time. In addition, sugar prices in Brazil are determined by prices in the world market, so that there is a correlation between Brazilian ethanol prices and world sugar prices.

Because flex fuel vehicles allow consumers to choose between gasoline and ethanol at the pump rather than at the showroom, ethanol prices are now becoming increasingly correlated to gasoline prices and, consequently, oil prices. We believe that the correlation among the three products will increase over time. Accordingly, a decline in sugar prices will have an adverse effect on the financial performance of our ethanol and sugar businesses, and a decline in oil prices may have an adverse effect on that of our ethanol business, including on its cash flows.

We may not successfully implement our plans to sell energy from our cogeneration projects, and the Brazilian government’s regulation of the energy sector may adversely affect our business and financial performance.

Our current total installed energy cogeneration capacity is approximately 981 MW, which is used to generate energy for our own industrial operations and to sell surplus energy to the Brazilian energy grid. The Brazilian government regulates the energy sector extensively. We may not be able to satisfy all the requirements necessary to enter into new contracts or to otherwise comply with Brazilian energy regulation. Changes to the current energy regulation or federal authorization programs, and the creation for more stringent criteria for qualification in future public energy auctions, in addition to lower prices, may adversely affect our results of operations from our cogeneration business.

Any failure in the implementation of these plans may have a material adverse effect on our business, financial condition and results of operations.

A reduction in market demand for ethanol or a change in governmental policies requiring ethanol be added to gasoline may have a material adverse effect on our business.

We produce and sell three different types of ethanol: hydrous ethanol, anhydrous ethanol for fuel and industrial ethanol. The primary type of ethanol consumed in Brazil is hydrous ethanol, which is used as an alternative to gasoline for flex fuel vehicles (as opposed to anhydrous ethanol which is used as an additive to gasoline).

10

Governmental authorities of several countries, including Brazil and the United States, currently require the use of anhydrous ethanol as an additive to gasoline. Since 1997, the Brazilian Sugar and Alcohol Inter-ministerial Council (Conselho Interministerial do Açúcar e Álcool), or “CIMA,” has set the percentage of anhydrous ethanol that must be used as an additive to gasoline. According to CIMA Resolution No. 1 dated March 4, 2015, the current anhydrous ethanol percentage for regular gasoline is 27% and for additive/premium gasoline is 25%. Approximately one-half of all fuel ethanol in Brazil is used to fuel automobiles that run on a blend of anhydrous ethanol and gasoline; the remainder is used in either flex fuel vehicles or vehicles powered by hydrous ethanol alone. Other countries have similar governmental policies requiring various blends of anhydrous ethanol and gasoline. In addition, flex fuel vehicles in Brazil are currently taxed at lower levels than gasoline-only vehicles, which has contributed to the increase in the production and sale of flex fuel vehicles. Any reduction in the percentage of ethanol required to be added to gasoline or increase in the levels at which flex fuel vehicles are taxed in Brazil, as well as growth in the demand for natural gas and other fuels as an alternative to ethanol, lower gasoline prices or an increase in gasoline consumption (versus ethanol), may cause demand for ethanol to decline and affect our business. In addition, ethanol prices are influenced by the supply and demand for gasoline; therefore, a reduction in oil prices resulting in a decrease in gasoline prices and an increase in gasoline consumption (versus ethanol), may have a material adverse effect on our business, results of operations and financial condition.

Government policies and regulations affecting the agricultural and fuel sectors and related industries could have a material adverse effect on our operations and profitability.

Agricultural production and trade flows are significantly affected by Brazilian federal, state and municipal, as well as foreign, government policies and regulations. Governmental policies affecting the agricultural industry, such as taxes, tariffs, duties, subsidies and import and export restrictions on agricultural commodities and commodity products, may influence industry profitability, the planting of certain crops versus others, the uses of agricultural resources, the location and size of crop production, the trading levels for unprocessed versus processed commodities, and the volume and types of imports and exports.

Future government policies in Brazil and elsewhere, in each case whether at the federal, state or local level, may adversely affect the supply, and demand for, and prices of, our products or restrict our ability to do business in our existing and target markets, which could adversely affect our financial performance. Our operations are currently concentrated in the state of São Paulo. Any changes affecting governmental policies and regulations regarding natural gas in the state of São Paulo (at the federal, state or municipal level) may have a material adverse effect on our business and financial performance.

In addition, petroleum and petroleum products have historically been subject to price controls in Brazil. Currently there is no legislation or regulation in force giving the Brazilian government the power to set prices for petroleum, petroleum products, ethanol or vehicular natural gas. However, given that Petrobras, the only supplier of oil-based fuels in Brazil, is a government-controlled company, prices of petroleum and petroleum products are subject to government influence, resulting in potential inconsistencies between international prices and internal oil derivative prices that affect our business and our financial results.

Raízen Energia, Raízen Combustíveis and Moove are subject to the application of regulatory penalties in the event of non-compliance with the terms and conditions of their respective authorizations, including the possible revocation of such authorizations.    

Raízen Energia performs generation activities in accordance with the regulation applicable to the energy sector and with the terms and conditions of authorizations granted by the Brazilian government through ANEEL. The duration of such authorizations varies from 20 to 35 years.

ANEEL may apply regulatory penalties to Raízen Energia in the event of non-compliance with the authorizations or with the regulations applicable to the energy sector. Such penalties may include, depending on the seriousness of the infraction, warnings, fines (in some cases up to 2% of our revenues for the last 12 months), restrictions on Raízen Energia’s operations, temporary suspension from participating in public bidding procedures to obtain new permissions, authorizations and concessions, prohibition from contracting with ANEEL, and revocation of its authorizations.

In addition, Raízen Combustíveis conducts its fuel distribution activities and Moove manufactures and distributes lubricants and base oil in accordance with the rules and regulations applicable to the oil and gas sector in Brazil as well as with the terms of the licenses and permits granted to them by the Brazilian government acting through the ANP. Failure to comply with the applicable rules and regulations or with the terms of the relevant licenses and permits may result in fines and other penalties (including confiscation or destruction of products, cancellation of product registrations, bans on certain facilities, and revocation of existing licenses and permits, among others). The applicable fines vary between R$5 thousand and R$5 million, depending on the gravity of the infraction.

11

Raízen Energia, Raízen Combustíveis and Moove cannot assure that they will not be penalized by ANEEL or ANP, as applicable, nor can they assure you that they will comply with all terms and conditions of their authorizations and with the regulation applicable to their respective businesses, which may have a material adverse effect on our business, results of operations and financial condition.

We face significant competition, which may have a material adverse effect on our market share and profitability.

The ethanol and sugar industries are highly competitive. Internationally, we compete with global ethanol and sugar producers in the United States, India, Thailand, Australia, among other countries and producers such as Poet, Inc., Archer-Daniels-Midland Company, Cargill, Inc. and A.E. Staley Manufacturing Company (a subsidiary of Tate & Lyle, PLC). Some of our competitors are divisions of larger enterprises and have greater financial resources than us. In Brazil, we compete with numerous small to medium-size producers. Despite increased consolidation, the Brazilian ethanol and sugar industries remain highly fragmented. Our major competitors in Brazil are Biosev (the second largest ethanol and sugar producer in Brazil), Tereos—Guarani (the third-largest ethanol and sugar producer in Brazil), Bunge, Santa Terezinha, São Martinho, Carlos Lyra, Tercio Wanderley, Zilor, Oscar Figueiredo, Da Pedra, and Irmãos Biagi and other ethanol and sugar producers in Brazil that market their ethanol and sugar products through the Cooperative of Sugarcane, Sugar and Ethanol Producers of the state of São Paulo (Cooperativa de Produtores de Cana-de-açúcar, Açúcar e Álcool do Estado de São Paulo), or “Copersucar.” Copersucar consists of producers in the states of São Paulo, Minas Gerais and Paraná. We are not a member of Copersucar.

We also face strong competition from international producers, particularly in highly regulated and protected markets, such as the United States and the European Union. With regards to sugar exports, we face intense competition from producers all around the world, including India, Thailand, and the European Union, among others. There are global producers of sugar whose costs are lower than those of Brazilian producers, including us, and whose production capacity and prices could lead to a decrease in prices on the global sugar market. Furthermore, we face very strong competition internationally with regards to ethanol, especially from the United States. Ethanol production in the United States is based on corn-derived ethanol and is undertaken on a greater scale than Brazilian ethanol production. Accordingly, a reduction in corn prices may lead to material reductions in the price of ethanol produced in the United States and result in increased competition in the Brazilian market.

Historically, imports of sugar have not provided substantial competition for us in Brazil due to, among other factors, the production and logistical cost-competitiveness of sugar produced in Brazil. If the Brazilian government were to create incentives for sugar imports, we could face increased competition in the Brazilian market by foreign producers. Many factors influence our competitive position, including the availability, quality and cost of fertilizer, energy, water, chemical products and labor. Some of our international competitors might have greater financial and marketing resources, larger customer bases and broader product ranges than we do. If we are unable to remain competitive with these producers in the future, our market share may be adversely affected.

The fuel distribution and lubricant market in Brazil is highly competitive. For example, we compete with domestic fuel distributors who purchase substantially all of their fuel from Petrobras and from suppliers based outside of Brazil. There are very few domestic competitors, such as us, who import lubricants into Brazil. In addition, we compete with producers and marketers in other industries that supply alternative forms of energy and fuel to satisfy the requirements of our industrial, commercial and retail consumers. Certain of our competitors, such as Petrobras, have larger fuel distribution networks and vertically integrated oil refineries, and may be able to realize lower per-barrel costs or higher margins per barrel of throughput. Our principal competitors in the fuel distribution and the lubricant market are larger and have substantially greater resources than we do. Because of their integrated operations and larger capitalization, these companies may be more flexible in responding to volatile industry or market conditions, such as shortages of crude oil and other feedstock or intense price fluctuations. The actions of our competitors could lead to lower prices or reduced margins for the products we sell, which could have a material and adverse effect on our business, results of operations and our financial performance.

12

Government laws and regulations governing the burning of sugarcane, including requirements in respect of the Legal Reserve, could have a material adverse impact on our business or financial performance.

The state of São Paulo and some local governments have established laws and regulations that limit our ability to burn sugarcane or that reduce and/or entirely prohibit the burning of sugarcane. The costs to comply with existing or new laws or regulations are likely to increase the cost of production, and, as a result, our ability to operate our own mills and harvest our sugarcane crops may be materially adversely affected.

In addition to restrictions that limit sugarcane burning and other environmental restrictions, we are required to preserve a percentage of our rural properties (sugarcane fields and other facilities), in order to contribute to a biodiversity preservation and ecologic rehabilitation fund known as the “Legal Reserve.” For rural areas located in the state of São Paulo, 20% of the property must be preserved to comply with the Brazilian Forest Code obligations.

Any failure to comply with these laws and regulations may subject us to legal and administrative actions. These actions can result in administrative or criminal penalties, including, but not limited to, suspension, shutdowns, a requirement to pay fines, which may range from R$50 to R$50 million and can be doubled or tripled in case of recidivism, an obligation to make capital and other expenditures or an obligation to materially change or cease some operations. In addition, we may be subject to civil liabilities, which include the obligation to redress any damages caused to the environment and/or public health. The demonstration of the cause-effect relationship between the damage caused and action or omission is sufficient to trigger the obligation to redress environmental damage.

Adverse weather conditions may reduce the volume and sucrose content of sugarcane that we can cultivate and purchase in a given harvest as well as demands for natural gas.

Our sugar production depends on the volume and sucrose content of the sugarcane that we cultivate or that is supplied to us by growers located in the vicinity of our mills. Crop yields and sucrose content depend primarily on weather conditions such as rainfall and temperature, which vary and may be influenced by global climate change. Weather conditions have historically caused volatility in the ethanol and sugar industries and, consequently, in our results of operations, by causing crop failures or reduced harvests. Flood, drought or frost, which may be influenced by global climate change, may have a material adverse effect on the supply and pricing of the agricultural commodities that we sell and use in our business. Future weather patterns may reduce the amount of sugar or sugarcane that we can recover in a given harvest or its sucrose content.

During the third and fourth quarter of 2014, a severe drought affected southeast Brazil, Comgás’ concession area, during which time residents were encouraged to save water. As a relevant portion of Comgás’ revenues is derived from the residential segment, and a significant portion of natural gas used by residential consumers is used for heating water, Comgás experienced a decrease in its net revenues derived from the residential segment. Therefore, our and Comgás’ business may be materially affected by unusual climate patterns.

Our business is subject to seasonal trends based on the sugarcane growing cycle in the Central-South region of Brazil.

Raízen Energia’s business is subject to seasonality according to the sugarcane growth cycle in the Central-South region of Brazil. The annual sugarcane harvesting period in the Central-South region of Brazil begins in April or May and ends in November or December. This creates fluctuations in Raízen Energia’s inventory and in its ability to generate energy, both of which usually peak in December, to cover sales between crop harvests (primarily from January to March), and a degree of seasonality in our gross profit, with ethanol and sugar sales significantly lower in the quarter ended on December 31. Rural producers of sugar and ethanol with whom Raízen Energia maintains a commercial relationship may experience a similar degree of seasonality, which may impact the supply of ethanol and/or other products necessary for Raízen Energia’s activities. Seasonality and any reduction in the volumes of sugar recovered could have a material adverse effect our business, results of operations and financial condition.

Furthermore, Rumo is subject to the seasonality that influences the sugarcane and grain harvest. During the peak months of the harvests, there is higher demand for transport and logistics operations. Rumo is also subject to the risk that sugarcane mills may change their production mix in favor of ethanol if the relative prices of the two products swing that way. This could reduce the demand for sugar logistics and transport.

13

Seasonality could have a material adverse effect on our business, results of operations and financial condition.

We may be adversely affected by a shortage of sugarcane or by high sugarcane costs.

Sugarcane is the principal raw material used by Raízen Energia (a company which we jointly control with Shell) for the production of ethanol and sugar. As of December 31, 2017, sugarcane purchased from suppliers accounted for 52% of our total crushed sugarcane. Historically, approximately 92% of the sugarcane purchased by us has been under medium- and long-term contracts with sugarcane growers, 2% on a spot basis and the remaining 6% from sugarcane growers with whom we have long-term relationships but no contractual arrangements. We generally enter into medium- and long-term supply contracts for periods varying from three and one-half to seven years. As of December 31, 2017, we also leased approximately 480,000 hectares to produce our own sugarcane in contracts with an average term of 12 years.

Our supply of sugarcane in Brazil may be significantly reduced as a result of the termination of supply contracts or lease agreements, which may result in a shortage of sugarcane supply and an increase in the price of sugarcane. If there is a shortage of sugarcane or any supply contracts or lease agreements are terminated, Raízen Energia may experience a material reduction in the sugarcane available for processing or an increase in sugarcane prices, which may have a material adverse effect on our business, results of operation and financial condition.

In Brazil, the price of sugarcane may increase as a result of changes in the criteria established by Association of Producers of Sugarcane, Sugar and Ethanol of the State of São Paulo (Conselho dos Produtores de Cana-de-açúcar, Açúcar e Álcool do Estado de São Paulo), or “Consecana,” which is composed of sugarcane producers and sugar mill operators. The price of sugarcane is set in supply agreements, lease agreements and partnership agreements and is partially fixed and partially variable, as provided for in the criteria set forth by Consecana. As a result, any changes to the criteria established by Consecana may lead to an increase in the cost of sugarcane, which may have a material adverse effect on our business, financial condition and results of operations.

In addition, in certain cases, as a result of the price-setting formulas in the contracts which we have entered into with our customers, we may not be able to pass on the full amount of these cost increases to our customers. This may have a material adverse effect on our business, financial condition and results of operations.

We are subject to developments affecting the Brazilian agribusiness sector as a whole.

We cannot assure you that in the future, the Brazilian agribusiness sector (i) will maintain the rate of growth and development which it has experienced in recent years and (ii) will not suffer losses due to unfavorable climatic conditions, reduction of the prices of the agricultural commodities in the national and international markets, changes in credit policies for domestic producers, both by government agencies and private entities, that may affect our income, as well as other economic and political crises that may affect the agricultural industry in general. Any deterioration in the overall condition of the Brazilian agribusiness sector may have a material adverse effect on us.

Raízen may be subject to expropriation of real estate intended for rural production.

The real estate used by Raízen, or by third parties with whom Raízen maintains a partnership or lease relationship, for the cultivation of sugarcane may be unilaterally expropriated by the Brazilian government for purposes of public and social interest, and we cannot assure you that the payment of the indemnification that they may have to pay to Raízen will be fair. Pursuant to Brazilian law, the Brazilian government may expropriate the real estate of rural producers where the sugarcane is planted by necessity or public utility or social interest, partially or totally. In the event of expropriation, we cannot assure you that the price paid by the Brazilian government will be fair, equivalent to the market value, or that it will effectively and adequately compensate Raízen for the amounts invested. Accordingly, the eventual expropriation of any real estate used by Raízen, or by third parties with whom Raízen maintains partnership or lease relationships, may adversely and significantly affect Raízen’s financial situation and results, and may also impact Raízen’s activities.

14

The use of alternatives to sugar and ethanol and technological advances may reduce demand for our sugar products in Brazil and other countries or require us to make substantial investments in order to remain competitive.

The development of alternative products to sugarcane and ethanol may reduce the demand for our products or materially reduce the demand for ethanol to be used as fuel. The use of alternative sweeteners has adversely affected the overall demand for sugar in Brazil and abroad. A substantial reduction in the demand for sugar and ethanol or increased consumption of alternative sweeteners may reduce the demand for sugar and ethanol we produce in Brazil and could have a material adverse effect on our business, results of operations and financial condition.

Any other alternative products or technological advances which reduce demand for our products may have a material adverse effect on our results of operations and financial condition.

Raízen Energia’s sugar and ethanol products are sold to a small number of customers who may be able to exercise significant bargaining power concerning pricing and other sale terms.

A substantial portion of Raízen Energia’s sugar and ethanol is sold to a small number of customers that acquire large portions of our production and thus may be able to exercise significant bargaining power concerning pricing and other sale terms. In addition, intense competition in the ethanol and sugar industries further increases the bargaining power of customers, which may have a material adverse effect on Raízen Energia’s sales volumes.

Raízen Energia’s export sales are subject to a broad range of risks associated with international operations.

In the fiscal year ended December 31, 2017, Raízen Energia’s net sales from exports represented 47% of our total net sales, while in the year ended December 31, 2016, the net sales from exports represented 54% of our total net sales. Furthermore, in the fiscal year ended December 31, 2017, the net sales from sugar exports were R$4,082 million, representing 31% of its total net sales for the period. In the year ended December 31, 2016, net sales from sugar exports were R$4,357 million, representing 33% of total net sales for the period. Further, in the fiscal year ended December 31, 2017, net sales from exports of ethanol were R$2,076 million, representing 16% of total net sales for that period and in the year ended December 31, 2016, net sales from ethanol exports were R$2,670 million, representing 20% of total net sales for that period.

Our exports of ethanol are subject to factors beyond our control which may affect the competitiveness of Brazilian ethanol in other markets, such as import regulations, tax legislation, incentives for local production and the establishment of distribution systems for hydrous ethanol in countries outside of Brazil. Our future financial performance will depend, to a significant extent, on economic, political and social conditions in our main export markets.

Most ethanol and/or sugar producing countries, including the United States and member countries of the European Union, protect local producers from foreign competition by establishing government policies and regulations that affect ethanol and sugar production, including quotas, import and export restrictions, subsidies, tariffs and duties. As a result of these policies, domestic ethanol and sugar prices vary greatly in individual countries. We have limited or no access to these large markets as a result of trade barriers. If these protectionist policies continue, we may not be able to expand our export activities at the rate we currently expect, or at all, which could have a material adverse effect on our business, results of operations and financial condition. Also, if new trade barriers are established in our key export markets, we may face difficulties in reallocating our products to other markets on favorable terms, and our business and financial performance may be adversely affected.

Failure to comply with the licenses and permits required for our business may have a material adverse effect on us.

We are required to obtain specific licenses and permits from governmental authorities in order to carry out certain of our operations. Raízen Combustíveis is also required to obtain specific licenses with respect to its terminals from the applicable environmental authorities, which are applied in particular to the emission, ejection and emanation of products and by-products resulting from distribution activities. The laws and regulations which govern these licenses may occasionally require us to purchase and install costly pollution-control equipment or to make operational changes to limit our impact on the environment and/or the health of our employees. Any failure to comply with the terms of such laws, regulations and licenses and permits may result in significant financial penalties, criminal sanctions, revocation of operating licenses and permits and/or the prohibition of certain of our activities.

15

Raízen Energia may be adversely affected if the outsourcing the mechanized sugarcane cutting becomes prohibited.

Raízen Energia is a defendant in a public civil action in which the Labor Public Prosecutor’s Office (Ministério Público de Trabalho) is seeking the prohibition of the outsourcing of planting, loading and transportation of sugarcane. Raízen Energia has appealed to the Superior Labor Court (Tribunal Superior do Trabalho) in order to overturn an unfavorable first instance decision. This appeal is currently awaiting judgment. If the Superior Labor Court rejects the appeal, Raízen Energia may be required to undertake these activities itself on a permanent basis (including hiring employees and acquiring appropriate machinery), which may have a material adverse effect on Raízen Energia.

Any mismatches between the cash outflows for the payment of litigation costs of Raízen and the time of receipt of the related reimbursement by the Joint Venture’s shareholders may lead to pressures on Raízen Energia and Raízen Combustíveis’ cash flows.

Pursuant to the framework agreement which was entered into during the formation of the Joint Venture, Raízen Energia has agreed that it will reimburse Cosan S.A. and Shell or will be reimbursed by them, as applicable, for any amounts received or paid in connection with legal proceedings, provided that the triggering events for such payments or receipts occurred before the formation of the Joint Venture on June 1, 2011 and provided that any such sums have actually been paid or received.

The framework agreement also provides that Cosan S.A. is required to indemnify Raízen for any expense related to litigation (tax, labor, civil and other) that has been caused by events prior to the formation of the Joint Venture.

Any mismatches between the cash outflows from Raízen for the payment of litigation costs and the time of receipt of the related reimbursement by Cosan S.A. or Shell, as applicable, or any failure by Cosan S.A. or Shell to reimburse Raízen, may lead to pressures on Raízen’s cash flows.

Brazilian courts, in some circumstances, have understood that a controlling shareholder, a successor entity of another corporation, an assignee company of another company’s assets and other companies subject to common control to the assignor or predecessor company shall all be liable, jointly and severally, for, among other obligations, labor, social security, civil, tax or environmental obligations of the assignor, assignee or predecessor. Therefore, we may be liable for obligations of their controlling shareholders for which we have not constituted and do not intend to constitute any provisions, which may adversely affect our business, results of operations and financial condition.

Raízen is subject to risks arising from legal proceedings based on claims related to alleged breaches of the intellectual property rights of third parties.

Raízen is subject to risks arising from legal proceedings based on claims related to alleged breaches of the intellectual property rights of third parties. Raízen may alter the way in which it produces, in whole or in part, products which third parties allege infringe their intellectual property rights and/or pay significant indemnification amounts, royalties or licensing fees in connection with the use of third parties’ patents or copyrighted materials. The filing of a lawsuit or the review of a product that is in violation of third parties’ intellectual property rights may adversely affect Raízen’s reputation and the demand for our products. In addition, new lawsuits require the attention of Raízen’s management, as well as additional costs for our defense and, in certain cases, the establishment of provisions that could affect our results.

16

Contamination of our products and other related risks could adversely affect our reputation, leading to judicial and administrative proceedings and/or resulting in the closure of our production facilities.

Certain of our products may have adverse effects on our consumers (including certain components, raw materials and supplies used to produce our products), including as a result of product contamination or following errors in the production or distribution chain.

Contamination of any of our products may result in a need for recalls or the beginning of legal and administrative proceedings against us, which may adversely affect our reputation, our business, the operation of our production facilities, our financial condition and our operating results. Any damage to our reputation could have a material adverse effect on us.

The modification, suspension, cancellation or non-renewal of certain tax benefits which we have been granted could have a material adverse effect on us.

We benefit from certain tax incentives, benefit programs and special regimes, such as:

• State of Goiás: (a) Tax benefit “Protege” that accrues at the tax rate of 2% levied on transactions with gas. This benefit permits an increase in the income of the Social Fund of the State of Goiás. The taxpayer is able to credit the respective amount through its accounting to permit the offset with further debts of ICMS (Imposto sobre Operações relativas à Circulação de Mercadorias e Prestação de Serviços de Transporte Interestadual e Intermunicipal e de Comunicação, a tax on sales and services which applies to goods, and transportation and communication) considering the rate as a reduction in the taxable basis of the gas acquired in the state of Goiás; (b) tax benefit “Protege II,” which permits a reduction in the taxable basis of 5% on all the basic transactions linked to ICMS in the state of Goiás (unlike the 2% reduction which is only applied to gas, the 5% rate applies to all other supplies) and (c) tax incentive “Produzir” that grants a reduction of ICMS payable of 63%.

• State of Mato Grosso do Sul: (a) ICMS – Presumed Tax Credit: The state of Mato Grosso do Sul implemented a reduction of 15.93% of the taxable basis of ICMS on ethanol transactions within the state; (b) Tax incentive that grants 67% of the outstanding balance of ICMS on sugar transactions to be deducted from the outstanding balance of the tax; and (c) other ICMS presumed tax credits granted on sugar and ethanol transactions.

• The states of Maranhão and Minas Gerais granted a reduction of calculation basis of ICMS on sales.

• State of São Paulo: (a) Suspension of ICMS levied on the importation of fixed assets and deferral on the acquisition of fixed assets; and (b) suspension of ICMS on gas transport.

• Federal tax incentive: Suspension of PIS and COFINS (respectively, the profit participation contribution and the social security financing contribution, both of which are social contributions due on certain revenues net of some expenses) levied on the importation of goods and of IPI on the sales and importation of inputs and raw materials.

We cannot assure you that these tax benefits will be maintained or renewed or that we will be able to obtain new tax benefits. If we lose our existing tax benefits due to our noncompliance with future requirements or if the current tax programs and agreements from which we benefit are modified, suspended, cancelled or not renewed, we could be materially and adversely affected. Moreover, the state tax benefits relating to ICMS from which we benefit may be declared unconstitutional by the Brazilian Supreme Court if they have been granted without the approval of all the States and the Federal District through the Brazilian National Council of Fiscal Policy (Conselho Nacional de Política Fazendária — CONFAZ). The Brazilian Supreme Court may grant retroactive or prospective effect to the declaration of unconstitutionality. The foregoing could result in a material adverse effect on us.

17

The shareholders’ and certain other definitive agreements with respect to the Joint Venture are subject to various put and call options and termination provisions.

Shell and Cosan have entered into certain definitive agreements with respect to the Joint Venture. Specifically, these agreements set forth the rights and obligations of each shareholder in respect of Cosan’s and Shell’s interest in the Joint Venture and establish certain options whereby Cosan or Shell may acquire the other shareholder’s interest in the Joint Venture, certain lock-up provisions, rules governing the intra-group transfers regarding to the economic group of Cosan and Shell, and remedies for fundamental breaches of the documentation governing the incorporation and operation of the Joint Venture. If triggered, these provisions may cause the Joint Venture, or our participation in it, to terminate prior to the scheduled expiration date of the agreements in June 2031.

In November 2016, Cosan and Shell executed amendments to certain agreements between them to remove the fixed-date call options over Raízen Energia and Raízen Combustíveis shares exercisable in 2021 and 2026 and replace them with certain call and put options exercisable by Shell or Cosan in certain circumstances, including, among others: (i) fundamental breaches of the obligations provided for in the agreements governing the Joint Venture, (ii) breach of anticorruption laws, (iii) insolvency or bankruptcy of a party, (iv) change of control, and (v) in the event of the death or disability of Cosan’s current Chairman, Mr. Rubens Ometto Silveira Mello. Moreover, Shell and Cosan agreed to renew the existing lock-up period for five years from the date of the execution of the amendment, following which the parties may sell their shares in each of Raízen Energia and Raízen Combustíveis subject to compliance with certain preemption rights in each other’s favor.

On February 23, 2017, TPG VI, a shareholder of Rumo, exercised its right to exchange 11,479,987 shares issued by Rumo for shares issued by Cosan S.A. pursuant to the shareholders’ agreement entered into in 2010 between Cosan Logística, TPG VI, GIF, Cosan S.A. and the Company. Cosan S.A. and GIF agreed to settle financially the stock replacement obligation through of payment of R$275.8 million and the shares received were valued at fair value in the amount of R$97.9 million and recorded as capital reserve.

Cosan S.A. and Shell were parties to a Comgás shareholders’ agreement dated December 19, 2012. The shareholders agreement established the terms and conditions that regulated the relationship between the parties as shareholders of Comgás. On December 12, 2017, Shell exercised a put option with us relating to shares in Comgás and, as a result, we bought a total of 21,805,645 shares in Comgás, which represents 16.77% of Comgás’s share capital, for R$1,042 million. As a result, Shell ceased to be a shareholder of Comgás and the Comgás shareholders’ agreement was terminated.

If any of these or other similar provisions are triggered under the shareholders’ agreements or any of the other related agreements, our partnerships, or certain rights we hold in connection therewith, could terminate prior to the scheduled expiration, which could adversely affect our results of operations.

Raw material and supply service costs are subject to wide fluctuations that could have a material adverse effect on our results of operations.

Raw materials used in our business and the cost of services we contract for the distribution of natural gas are subject to wide fluctuations depending on market conditions. These prices are influenced by several factors over which we have little or no control, including, but not limited to international and national economic conditions, regulations, government policies, tariff adjustments and global effects of supply and demand. We cannot ensure that our tariff adjustment will be conducted in a timely manner or be sufficient to reflect and/or offset increases in inflation, operation costs and expenses, amortization of investments and taxes. As a result, we might not be able to pass on the increase in our cost structure to our customers, which could decrease our profit margin and result in a material adverse effect on our business, financial condition and results of operations.

We may not successfully acquire or develop additional production capacity through greenfield projects or expansion of existing facilities.

We may explore growth opportunities in the future through the acquisition or development of greenfield projects or through the expansion of our existing facilities. For example, we do not have environmental or other permits, designs or engineering, procurement and construction contracts with respect to any potential projects. Any such growth is subject to factors that are beyond our control, such as the existence of opportunities that fit our profile, as well as risks associated with due diligence, project development timelines and governmental approvals. As a result, we may not complete these projects on a timely basis or at all, and may not realize the related benefits we anticipate. In addition, we may be unable to obtain the required financing for these projects or the expansion of our existing facilities on satisfactory terms, or at all.

18

The integration of greenfield projects or expansion of our existing facilities may result in unforeseen operating difficulties and may require significant financial and managerial resources that would otherwise be used for our current operations. Planned or future greenfield projects or expansion of existing facilities may not enhance our financial performance.

Any failure in the implementation of growth projects and/or expansion of existing facilities may have a material adverse effect on our business, financial condition and results of operations.

Fire and other disasters could affect our agricultural and manufacturing properties and our facilities and distribution networks, which would have a material adverse effect on our production and distribution volumes and, consequently, results of operations.

Our operations are subject to risks affecting our agricultural properties and facilities and distribution networks, including fire potentially destroying some or all of our crop and facilities. In addition, our operations are subject to hazards associated with the manufacture of flammable products and transportation of raw materials and flammable products. Our insurance coverage may not be sufficient to provide full protection against these types of casualties.

Crop disease and pestilence may strike our crops which may result in destruction of a significant portion of our harvest.

Crop disease and pestilence can occur from time to time and have a devastating effect on our crops, potentially rendering useless or unusable all or a substantial portion of affected harvests. Even when only a portion of the crop is damaged, our business, results of operations and financial condition could be adversely affected because we may have incurred a substantial portion of the production cost for the related harvest. The cost of treatment of crop disease tends to be high. Any serious incidents of crop disease or pestilence, and related costs, may adversely affect our production levels and, as a result, our net sales and overall financial performance.

Anticompetitive practices in the fuel distribution market may distort market prices.

In the last few years, anticompetitive practices have been one of the main problems affecting fuel distributors in Brazil. Generally these practices have involved a combination of tax evasion and fuel adulteration, such as the dilution of gasoline by mixing solvents or adding anhydrous ethanol in an amount greater than that permitted by applicable law (the overall taxation of anhydrous ethanol is lower than hydrated ethanol and gasoline).

Taxes constitute a significant portion of the cost of fuels sold in Brazil. For this reason, tax evasion by some fuel distributors has been prevalent, which allows them to lower the prices they charge. These practices have enabled certain distributors to supply large quantities of fuel products at prices lower than those offered by the major distributors, including us, which has resulted in a considerable increase in the sales volumes of the distributors who have adopted these practices. The final prices for fuels are calculated based on the taxes levied on their purchase and sale, among other factors. If such practices become more prevalent, it could lead to lower prices or reduced margins for the products we sell, which could have a material adverse effect on our business, results of operations or financial condition.

In Brazil, Petrobras is the main supplier of base oils, the primary distributor of fuel and the dominant company in the natural gas sector. In the event of an interruption of supply of fuels from Petrobras, significant disruption to Raízen Combustíveis, Comgás and Moove operations sales may occur.

Petrobras is the principal supplier of fuel in Brazil and the distribution policies it sets forth directly affect the Brazilian energy matrix. With the recent discoveries in the pre-salt oil fields, and the beginning of production in the Santos basin, which is located close to our concession area, we face uncertainties regarding the production of alternative fuel. Petrobras is also the subject of “Lava Jato” investigations by the Brazilian Federal Police, the Brazilian Federal Prosecutor’s Office, the CVM and the SEC in connection with corruption allegations, which could cause disruption in Petrobras’ activities. Significant disruption to our fuels, lubricant and natural gas sales may occur in the event of an interruption of supply from Petrobras. Any interruption would immediately affect our ability to provide fuel, lubricant and natural gas products to our customers. If we are not able to obtain an adequate supply of fuel, base oil and natural gas products from Petrobras under acceptable terms, we may seek to meet our demands through purchases on the international market. The cost of fuel and base oil products on the international market may be more expensive than the price we obtain through Petrobras.

19

In addition, we may be adversely affected if Petrobras significantly modifies its business plan or reduces its activities related to the distribution of fuel in Brazil. In particular, the most recently published divestment plan of Petrobras suggests that Petrobras is scaling back its positions in logistics, which may result in disruption of logistics services and result in changes to distribution policies which may adversely affect the competitiveness of fuel distributors.

Disruption of Raízen Energia’s transportation and logistics services or insufficient investment in public infrastructure could adversely affect our operating results.

One of the principal disadvantages of the Brazilian agriculture sector is that key growing regions lie far from major ports. As a result, efficient access to transportation infrastructure and ports is critical to the growth of Brazilian agriculture as a whole and of our operations in particular. As part of its business strategy, Raízen Energia is investing in areas where existing transportation infrastructure is underdeveloped. Improvements in transportation infrastructure are likely to be required to make more agricultural production accessible to export terminals at competitive prices. A substantial portion of Brazilian agricultural production is currently transported by truck, a means of transportation significantly more expensive than the rail transportation available to U.S. and other international producers. Raízen Energia’s dependence on truck transport may affect our position as a low-cost producer, such that its ability to compete in world markets may be impaired.

Even though road and rail improvement projects have been considered for some areas of Brazil, and in some cases implemented, substantial investments are required for road and rail improvement projects, which may not be completed on a timely basis, if at all. Any delay or failure in developing infrastructure systems could hurt the demand for our products, impede our delivery of products or impose additional costs on us. Raízen Energia currently outsources the transportation and logistics services necessary to operate its business. Any disruption in these services could result in supply problems at Raízen Energia’s processing plants and impair its ability to deliver processed products to customers in a timely manner. In addition, a natural disaster or other catastrophic event could result in disruption in regional transportation infrastructure systems affecting our third-party transportation providers.

The production of lubricants and the storage and transportation of fuel products and lubricant products are inherently hazardous.

The complex manufacturing operations we perform at our lubricants oil blending plant involve a variety of safety and other operating risks, including the handling, production, storage and transportation of toxic materials. These risks could result in personal injury and death, severe damage to or destruction of property and equipment and environmental damage. A material accident at one of our plants, service stations or storage facilities could force us to suspend our operations and result in significant remediation costs and lost revenue. In addition, insurance proceeds, if available, may not be received on a timely basis and may be insufficient to cover all losses, including lost profit. Equipment breakdowns, natural disasters, and delays in obtaining supplies or required replacement parts or equipment could also have a material adverse effect on our manufacturing operations and consequently our results of operations. Disruption of transportation and logistics services or insufficient investment in public infrastructure could have a material adverse effect on our operating results.

We may be adversely affected by unfavorable outcomes in pending legal proceedings.

We are involved in a significant number of tax, civil and labor proceedings as to which, at December 31, 2017, we recorded a provision totaling R$1,348 million for proceedings in which we deem the risk of loss as probable (R$766 million net of judicial deposits or restricted bank accounts). We cannot predict whether we will prevail in these or other proceedings, or whether we will have to pay significant amounts, including penalties and interest, as payment for our liabilities, which would materially and adversely impact our business and financial performance.

In addition, unfavorable decisions in criminal proceedings involving members of our management may have a material adverse effect on us. Certain members of our management have been named as defendants in criminal proceedings (1) in their capacity as officers of the predecessor entity of Raízen Energia for alleged artificial price fixing of fuel and the formation of a cartel with the purpose of establishing control over the regional market, (2) in their capacity as officers of Raízen Energia and Cosan for alleged tax evasion carried out by these entities, and (3) in their capacity as officers of the predecessor entities of Raízen for the crimes of disobedience and pollution in connection with the alleged burning of sugarcane contrary to a judicial decision. In the event of a final non-appealable conviction, one or more of these officers may be barred from holding executive positions within our Company, and depending on the development of the proceedings, our reputation in the opinion of our clients, suppliers and investors may be materially adversely affected.

20

One of Rumo’s subsidiaries, Malha Paulista, is party to a labor class action (ação civil pública) stemming from allegations by the Labor Prosecutor’s Office that certain persons working for MS Teixeira were working in degrading conditions analogous to indentured servitude. MS Teixeira was as a subcontractor to Malha Paulista’s contractor for certain services, Prumo Engenharia. Malha Paulista has been ordered by the courts to undertake (and/or refrain from undertaking) various actions with respect to the working environment and to pay an indemnity for collective moral damages, as well as fines of R$100 thousand per breach or per worker in the event of future labor breaches. As of the date of this annual report, neither we nor Rumo have made provisions with respect to these proceedings as the external counsel advising Rumo on these proceedings has assessed the risk of loss as possible. An adverse outcome in this lawsuit could result in losses of approximately R$26.9 million to Rumo, and adversely affect our reputation. If Malha Paulista’s appeal is rejected by the superior courts or if the Labor Prosecutor’s Office’s allegation of degrading working conditions analogous to indentured servitude is confirmed, the final outcome of the action may have a material adverse effect on Rumo’s business, financial condition and results of operations—including as a result of the acceleration of certain financial agreements to which Rumo is a party—and Rumo may suffer damage to its reputation. Any such developments could have a material adverse effect on us.

We cannot predict whether we will prevail in these or other proceedings, or whether we will have to pay significant amounts, including penalties and interest, as payment for our liabilities, which would materially and adversely impact our business, results of operations and financial condition. If we are the subject of an unfavorable outcome in any of these legal proceedings, the amount of such unfavorable decisions will have a material adverse effect on our financial position and operating results.

Transporting gas involves numerous risks that may result in accidents and other operating risks and costs that could adversely affect our results of operations, cash flows and financial condition.

Our activities involve a variety of inherent hazards and operating risks, such as leaks, accidents and mechanical problems, which could cause substantial financial losses. In addition, these risks could result in loss of human life, significant damage to property, environmental pollution and impairment of our operations, which in turn could lead to substantial losses. In accordance with customary industry practice, we maintain insurance against some, but not all, of these risks and losses. The location of pipelines near populated areas, including residential areas, commercial business centers and industrial sites, could increase the level of damages resulting from these risks. The occurrence of any of these events if not fully covered by insurance could adversely affect our results of operations, cash flows and financial condition.

The volatility and uncertainties in international oil and gas prices as well as a significant depreciation of the real relative to the U.S. dollar may affect the operating costs and competitive positions of our businesses, which could adversely affect our results of operations, cash flows and financial condition.

Natural gas and oil prices historically have been volatile and may continue to be volatile in the future. Prices for natural gas and oil are subject to a variety of factors that are beyond our control. These factors include, but are not limited to, the level of consumer demand for, and the supply of, natural gas, processing, gathering and transportation availability, statutory gas supply purchase obligations, price and availability of alternative fuel sources, weather conditions, natural disasters and political conditions or hostilities in natural gas producing regions.

In addition, the amounts we pay under our natural gas supply agreements are composed of two components: (1) one that is indexed to a basket of combustible oils in the international market that is adjusted quarterly and (2) one that is adjusted annually based on the inflation rate. We have no control over either of these components. Furthermore, natural gas supply agreements often take the form of a “take or pay” agreement, pursuant to which we might be required to pay the difference in amounts between actual consumption and the contract amount. Variations and uncertainties in the price and demand of oil and gas are beyond our control and may adversely affect our results of operations.

Renewal of our natural gas concession agreement is not guaranteed, the terms we will receive if such renewal is granted could adversely affect our results of operations, cash flows and financial condition and our growth strategy would be materially adversely affected if we cannot obtain new concessions on similar terms or if our existing concession is terminated.

We, through our affiliate Comgás, carry out our natural gas distribution activities pursuant to a concession agreement entered into with the Government of the State of São Paulo and regulated by ARSESP for a 30-year term with a one-time possibility of renewal for an additional 20 years at the discretion of the Government of the State of São Paulo, subject to certain conditions, including approval by ARSESP. The Brazilian Constitution (Article 175) requires that all concessions relating to public services be awarded through a public bidding process.

21

Due to the discretionary power of the Government of the State of São Paulo in granting the renewal of our concession agreement, we cannot assure you that our concession agreement will be renewed, or that it will be renewed on the same terms. Moreover, pursuant to the terms of our concession agreement, the Government of the State of São Paulo may terminate our concession agreement upon the occurrence of certain conditions. If our concession agreement is not renewed, or is renewed with less favorable terms, or is terminated, our business, financial condition and results of operations will be materially adversely affected.

Our business is subject to regulation, control and supervision of ARSESP, which could affect our financial performance. ARSESP establishes the maximum values of our rates and regulates and supervises our business. Pursuant to our concession agreement, every five years – or whenever ARSESP deems the economic and financial balance of the concession agreement to be adversely affected due to the variation of costs incurred by Comgás – our rates are reviewed by ARSESP, which directly affects our margins and our results, either positively or negatively. Such margins are adjusted annually by the IGP-M minus the efficiency factor determined for each tariff cycle by ARSESP. As a result, the implementation of our growth strategy and the normal course of our business may be adversely affected by government actions.

We cannot guarantee that changes arising from the tariff review process will be supportive of our strategy in our subsidiary Comgás.

The principal rights and obligations of the holders of concessions are included in the concession agreement, and in the regulations established by ARSESP. Among the items provided in the concession agreement is the tariff review, which should occur in five-year cycles and serves to reestablish the economic and financial balance of the concession, setting the average margin for the cycle and the rates that will apply for each segment. The tariff review process, which should have been concluded in May 2014, is still in process. We cannot assure you that in the future tariffs will be set at a level that would permit us to continue to operate profitably.

In addition, in its regulatory capacity, ARSESP may impose penalties on us if we fail to comply with any provision of the concession agreement. Depending on the severity of noncompliance, applicable penalties include, among others:

• assessments;

• fines;

• bans on the construction of new facilities and equipment;

• forfeiture of the concession; and

• impediments from participating in public bidding processes and from being awarded new concessions.

We cannot guarantee that we will not be penalized by ARSESP for breaching our natural gas concession agreement or that the concession will not be revoked in the future. The compensation to which we would be entitled in the event of possible revocation of the concessions may not be sufficient to recover the full value of certain assets. Therefore, the imposition of fines or penalties on us or the revocation of the concessions may have a material adverse effect on our financial condition and results of operations.

We depend on third parties to provide our customers and us with facilities and services that are integral to our business.

We have entered into agreements with third-party contractors to provide facilities and services required for our operations, including storage facilities and transportation services for our ethanol and sugar operations. The loss or expiration of our agreements with third-party contractors or our inability to renew these agreements or to negotiate new agreements with other providers at comparable rates could harm our business and financial performance. Our reliance on third parties to provide essential services on our behalf also gives us less control over the costs, efficiency, timeliness and quality of those services. Contractors’ negligence could compromise the safety of the transportation of ethanol from our production facilities to our export facilities and expose us to the risk of liability for environmental damage caused by such third parties. We expect to be dependent on such agreements for the foreseeable future, and if we enter any new market segments, we will need to have similar agreements in place. Also, pursuant to Brazilian law, if labor authorities deem that such third-party contractors are performing activities considered to be part of our core business, we may be exposed to fines, prohibition on the outsourcing of such activities and labor liabilities in connection with the outsourced workforce.

Our international operations expose us to political and economic risks in other countries.

We derive 4.4% of our revenues from exports. In particular, Moove distributes and sells Mobil brand products manufactured in Brazil and sold in Bolivia, Paraguay and Uruguay, and, in July 2012, we acquired Comma, which produces and distributes lubricants throughout Europe and Asia. In addition, Moove has recently started a new distribution operation under the Mobil brand, in Spain, aligned with its strategy to leverage the ExxonMobil partnership and expand abroad.

22

Our international activities expose us to risks not faced by companies that operate solely in Brazil. Risks associated with our international operations include: (1) foreign exchange controls; (2) changes in the political or economic conditions in a specific country or region, especially in emerging markets; (3) potentially negative consequences resulting from changes to regulatory requirements; (4) difficulties and costs associated with our observance of different laws, treaties and complex international regulations; (5) tax rates that may exceed those applicable in Brazil and other countries or gains that may be subject to withholding regimes and an increase in repatriation taxes; (6) imposition of trade barriers; and (7) limitations on the repatriation of undistributed profits. The realization of any of these risks may have a material adverse effect on our business, results of operations or financial condition.

We may not be able to maintain or renew certain agreements with third parties which are important to our business.

Our business, financial condition and results of operations may be materially and adversely affected if we are unable to maintain or renew certain agreements (including, without limitation, supply agreements, service contracts, licensing agreements, distribution agreements, joint ventures, partnerships and others) with third parties which are important to our business and operations.

On November 1, 2017, we acquired Stanbridge, which distributes lubricants and fuels in some regions of the United Kingdom. The company has an exclusive supply service contract with the company operating Heathrow Airport to supply fuel, fuel management services and certain other products and services to Heathrow Airport. This contract is expected to terminate in 2019. While negotiations have begun to renew this agreement, we cannot assure you that such negotiations will be successful. Failure to renew such agreement could materially and adversely affect our results of operations.

We, through our subsidiary Moove, are the manufacturer and exclusive distributor of lubricants in Brazil based on formulas that have been provided under the terms of the Principal Lubricants Agreement that we have entered into with ExxonMobil, which will expire on December 1, 2018. On March 19, 2018, we entered into an agreement with ExxonMobil Lubricants Trading Company which grants our subsidiary Moove the exclusive production, import, distribution and marketing rights in Brazil, Bolivia, Paraguay and Uruguay of lubricants and certain other related products under the Mobil brand until November 30, 2038. This agreement will come into force on December 1, 2018. The termination or failure to renew these agreements, or the failure by ExxonMobil to adequately maintain and protect its intellectual property rights, could materially and adversely affect our results of operations or could require significant unplanned investments by us if we are forced to develop or acquire alternative technology. In the future, it may be necessary or desirable to obtain other third-party technology licenses relating to one or more of our products or relating to current or future technologies to enhance our product offerings. However, we may not be able to obtain licensing rights to the needed technology or components on commercially reasonable terms or at all.

In addition, our natural gas supply agreement with Petrobras that is sourced out of Bolivia comes due in 2019 and we cannot assure you that it will be renewed. See “Item 3. Key Information––D. Risk Factors—Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate—Our business would be materially adversely affected if operations at our transportation and distribution facilities experienced significant interruptions. Our business would also be materially adversely affected if the operations of our customers and suppliers experienced significant interruptions.”

We incur substantial costs to comply with environmental regulations and may be exposed to liabilities in the event we fail to comply with these regulations or as a result of our handling of hazardous materials.

We are subject to various Brazilian federal, state and municipal environmental protection and health and safety laws and regulations governing, among other matters:

• the issuance and renewal of valid environmental licenses and authorizations;

• the use of water;

• the generation, storage, handling, use and transportation of hazardous materials;

• sugarcane burning;

• wildlife preservation;

• the protection of cultural and historic sites;

• the emission and discharge of hazardous materials into the ground, air or water; and

• the health and safety of our employees.

23

We are also required to obtain environmental and health permits and/or authorizations (such as installation and operation permits as well as permits for the removal of vegetation) from governmental authorities for certain aspects of our operations. Failure to obtain environmental and/or health permits or comply with the conditions under which such permits are issued could subject us to criminal, administrative and/or civil liabilities. These laws, regulations and permits often require us to purchase and install expensive pollution control equipment or to make operational changes to limit actual or potential impacts on the environment and/or health of our employees. In addition, Brazilian environmental laws establish restrictions to obtain financing from public entities in case of breach of certain environmental protection obligations. Any violations of these laws and regulations or permit conditions can result in substantial fines, criminal sanctions, revocations of operating permits and/or shutdowns of our facilities.

Due to the possibility of changes to environmental and/or health regulations and other unanticipated developments, the amount and timing of future environmental and health expenditures may vary substantially from those currently anticipated. Under Brazilian environmental laws, we could be held strictly liable for all of the costs relating to any contamination at our or our predecessors’ current and former facilities and at third-party waste disposal sites used by us or any of our predecessors. We could also be held responsible for any and all consequences arising out of human exposure to hazardous substances, such as pesticides, herbicides, soil or groundwater contamination or other kinds of environmental damage.

We are party to a number of administrative and judicial proceedings for alleged failures to comply with environmental and health laws (especially relating to contaminated areas and environmental damages caused by sugarcane burning), which may result in fines, shutdowns or other adverse effects on our operations. Actions that give rise to administrative proceedings may also lead to civil or criminal claims against us. We have not recorded any relevant provisions or reserves for these proceedings as we do not currently believe that they will result in liabilities material to our business or financial performance. Our costs of complying with current and future environmental and health and safety laws, and our liabilities arising from past or future releases of, or exposure to, hazardous substances could adversely affect our business or financial performance.

Our business would be materially adversely affected if operations at our transportation and distribution facilities experienced significant interruptions. Our business would also be materially adversely affected if the operations of our customers and suppliers experienced significant interruptions.

The distribution of natural gas is by its nature subject to inherent risks, including interruptions or disturbances in the natural gas distribution system which may be caused by accidents or force majeure events. Our operations are dependent upon the uninterrupted operation of our terminal and storage facilities and various means of transportation and distribution facilities. We are also dependent upon the uninterrupted operation of certain facilities owned or operated by our suppliers and customers. Operations at our facilities and at the facilities owned or operated by our suppliers and customers could be partially or completely shut down, temporarily or permanently, as the result of any number of circumstances that are not within our control, such as:

• catastrophic events, including hurricanes and floods;

• environmental matters (including environmental licensing processes or environmental incidents, contamination, wildlife preservation obligations and others);

• labor difficulties (including work stoppages, strikes and other events); and

• disruptions in the supply of our products to our facilities or means of transportation.

Any significant interruption at these facilities or inability to transport products to or from these facilities or to or from our customers for any reason could subject us to liability in judicial, administrative or other proceedings, even for disruptions caused by events outside of our control. If we are held liable for such events, results of operations and cash flow would be materially adversely affected.

In addition, the majority of our supply of natural gas originates from Bolivia pursuant to our agreement with Petrobras. Any changes in the political or economic conditions of Bolivia to the extent that they impact the ability of Petrobras to supply us with natural gas, may have a material adverse effect on us. In particular, our natural gas supply agreement with Petrobras that is sourced out of Bolivia comes due in 2019 and we cannot assure you that it will be renewed. Petrobras has recently announced its intention to cease distributing natural gas to distributors in order to focus on supplying its own refineries and thermal plants and therefore not renew our natural gas supply agreement in 2019. There can be no assurance that we will be able to identify new suppliers for the natural gas we receive through Petrobras or negotiate natural gas supply agreements with any such suppliers on favorable terms, which could materially and adversely affect us, our financial condition and results of operations.

Rumo depends on a few major customers for a significant portion of its revenue.

The majority of cargo Rumo transports is for the agricultural commodities industry. Rumo’s major clients are export companies participating in this market, such as Amaggi, ADM, Bunge, Cargill, Louis Dreyfus and Raízen. In the fiscal year ended December 31, 2017, Bunge accounted for 15% of Rumo’s total net revenue from services, while Rumo’s six major clients accounted for 52.5% of Rumo’s total net revenue from services. In the fiscal year ended December 31, 2016, Bunge accounted for 17.6% of Rumo’s total net revenue from services, while Rumo’s six major clients accounted for 51.6% of Rumo’s total net revenue from services in the same period. Bunge is the principal customer of Rumo’s Northern Operations and Southern Operations and is active in agricultural commodities, especially corn, soy and derivatives thereof, loading cargo in transshipment terminals destined for ports which Rumo operates.

Rumo’s major clients in the rail sector are export companies such as Amaggi, ADM, Bunge, Cargill, Louis Dreyfus and Raízen. In the fiscal year ended December 31, 2017, Bunge accounted for 14.5% of Rumo’s net revenue from services in the rail sector, while Rumo’s six major clients in the rail sector jointly accounted for 46.4% of Rumo’s net revenue from services in that sector. In 2016, Bunge accounted for 21% of Rumo’s net revenue from services in the rail sector, while Rumo’s six major clients in the rail sector accounted for 58% of Rumo’s net revenue from services in that sector.

Rumo’s largest clients in the port elevation sector include Bunge, Czarnikow, Cofco, Wilmar, Raízen and Sucden. In the fiscal year ended December 31, 2017, Raízen accounted for 17.9% of our net revenue from services in the port elevation sector, while Rumo’s six largest clients in the port elevation sector collectively accounted for 52.3% of Rumo’s net revenue from services in that sector. On December 31, 2016, Raízen accounted for 24.1% of Rumo’s net revenue from services in the port elevation sector, while Rumo’s six largest clients in the port elevation sector accounted collectively for 68.9% of Rumo’s net revenue from services in that sector.

We cannot guarantee that Rumo will obtain similar revenue from its major clients in the future. Any change by Rumo’s major clients in their demand for transportation services, including logistics services, may have a material adverse effect on Rumo’s business, financial condition and results of operations. Moreover, Rumo’s revenue predominantly derives from transportation agreements between Rumo and its clients. We cannot guarantee that these transportation agreements will be renewed once they have expired, which may adversely affect Rumo’s business, financial condition and results of operations.

Rumo’s significant debt could adversely affect its financial health and prevent it from fulfilling its debt obligations, which would have a material adverse effect on us, our financial condition and our results of operations.

Rumo has a significant amount of debt. As of December 31, 2017, Rumo’s gross debt was R$9,670.9 million, of which R$1,594.0 million was short-term debt.

Rumo’s debt level and the composition of its debt could have important consequences to its business. For example, it could: (1) require Rumo to reserve a substantial part of its operational cash flows to pay principal and interest on Rumo’s debt, which will reduce the availability of its cash flow to fund working capital, capital expenditures, acquisitions and investments; (2) limit its flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; (3) limit its ability to borrow additional funds, obtain bank guarantees or collateral insurance and generally increase its borrowing costs; and (4) place Rumo at a competitive disadvantage compared to our competitors that have less debt.

Any of the aforementioned developments could have a material adverse effect on us, our financial condition and results of operations.

Significant deterioration in Rumo’s short-term liquidity could materially affect our business, result of operations and financial condition.

Rumo’s adjusted working capital (defined as current assets excluding cash and cash equivalents, marketable securities and restricted cash) less current liabilities (excluding short-term loans and financings) was negative R$841.8 million as of December 31, 2017 and negative R$802 million as of December 31, 2016.

If Rumo fails to improve its short-term liquidity, we may face difficulties in fulfilling its obligations relating to financing agreements, and agreements with suppliers and/or subcontractors, among others. For example, as of December 31, 2017, Rumo’s material contractual financial obligations maturing in less than one year totaled R$3,939.9 million (amortization only), while such obligations with maturities between one to two years totaled R$2,020.9 million (based on contracted undiscounted cash flow). Rumo’s failure to comply with these obligations and/or other undertakings may have a material adverse effect on our business, results of operations and financial condition.

Rumo’s concessions to operate port terminals are subject to expiration, limitation on renewal and early termination by the granting authority.

Rumo leases 118,434.38 square meters of property located in the port of Santos (state of São Paulo), which has two docking cradles for loading sugar and solid agricultural bulk (corn and soy). This property is leased pursuant to lease agreement PRES-05/96, which matures on March 6, 2036. Pursuant to Article 57 of the Ports Modernization Law and Article 19 of Decree No. 8,033/2013, recently amended by Decree 9,048/2017, lease agreements may be extended for up to the limit of 70 years. Pursuant to the lease agreement, Rumo has an obligation to make investments totaling an estimated R$308 million, of which we have already invested 82%. Rumo estimate that the investments shall be completed by February 2019.

Rumo also holds equity interests in: (1) Terminal XXXIX and the adjacent areas for moving agricultural products and bulk as well as other goods capable of being transported in those port installations, through a port lease agreement due to expire in 2022; (2) facilities, equipment and track for rail transport of goods and import/export through the right bank of the port of Santos, by means of a lease agreement with Portofer Transporte Ferroviário Ltda. due to expire in 2025; (3) Terminal de Granéis do Guarujá (TGG) located on the left bank of the port of Santos, for the transport of solid and liquid bulk, through an area used by Rumo Malha Norte S.A., or “Malha Norte” via a leasing agreement due to expire in 2022; and (4) Terminal Marítimo do Guarujá (TERMAG), located on the left bank of the port of Santos, mainly for the transport of solid and liquid bulk, through an area used by Malha Norte via a lease agreement due to expire in 2022.

There are ongoing legal proceedings regarding whether the lease agreements (as amended) relating to Terminal XXXIX, Terminal de Granéis do Guarujá and Terminal Marítimo do Guarujá should be subject to the public procurement regime. These proceedings are currently under appeal in the Brazilian superior courts (Superior Tribunal de Justiça and Supremo Tribunal Federal). With regards to the Portofer lease agreement, there is a public civil action filed by the Brazilian Federal Prosecutors’ Office, to challenge the legal validity of the agreement.

If Rumo fails to comply with the applicable regulatory rules or contractual obligations relating to Terminals 16 and 19, its lease may be terminated early pursuant to the Concessions Law (Law No. 8,987/1995), which applies to port leases. Below is a list of the termination events applicable to the port lease agreements:

• expiration of the lease agreement (currently in 2036, which can be legally extended up to 2066 through new investments);

• encampação, which is the possibility of expropriation of the port concessions by the granting authority during the contractual term. Such expropriation must be for public interest, performed pursuant to applicable authorizing law and accompanied by the payment of an indemnity for investments not yet depreciated, if applicable;

• a statement of forfeiture, which occurs, at the granting authority’s sole discretion, in case of total or partial non-performance of the lease, without prejudice to the application of other contractual penalties. The forfeiture may be declared under the following circumstances: (1) the service is not being provided adequately (i.e., there has been a breach of the minimum transport requirements); (2) failure to undertake the investments stipulated in the agreement; (3) breach of contractual obligations; (4) transfer of the agreement without prior consent from the granting authority; (5) obstruction of audits carried out by the granting authority; (6) changes to the contractual objective; (7) failure to maintain or conserve the leased facilities; (8) default in financial obligations set out in the agreement; or (9) loss by us of the economic, technical and operating conditions required for the adequate provision of services set out in the agreement. The forfeiture must be preceded by the verification of the default in an administrative proceeding in connection with which we have a right of defense;

• termination by the lessee in the event of breach of contractual provisions or rules established by the granting authority by means of judicial action for this specific purpose;

• annulment; and

• bankruptcy or extinction of the lessee.

The lease agreements and applicable legislation confer several rights of the granting authority pursuant to the specific rules and regulations for the industry. Accordingly, there are contractual provisions that allow, among other things, amendments to the agreement, assignment and/or transfer of the lease agreement (the latter subject to prior consent from the granting authority), provided, however, that all amendments to the agreement must abide by the rules and proceedings set out in the specific law or regulation.

26

Termination of Rumo’s port lease agreements may adversely impact Rumo’s transportation costs and the turnaround time for the export of Rumo’s products, as well as Rumo’s revenues from service agreements related to Rumo’s port facilities.

In addition, port assets deemed essential to the continuity of port operations will revert to the granting authority upon expiration of the concession. The reversion following expiration is subject to indemnification for investments in assets not yet amortized or depreciated which were undertaken to guarantee service continuity. Upon termination of the concession, it is possible that the investments made in those assets will have not been entirely amortized or depreciated. In this case, Rumo and the granting authority will negotiate the amount of any indemnification for such investments, to the extent such investments have been previously approved by the granting authority. As the final decision on this amount will be made solely by the granting authority, Rumo’s financial condition may be negatively impacted if indemnification eventually approved is not sufficient to compensate us for the investments made.

Any of the aforementioned developments could have a material adverse effect on us, our financial condition and results of operations.

We are unable to estimate the impact of new regulations applicable to port operations in Brazil.

Until December 6, 2012, port operations in Brazil were governed by Federal Law No. 8,630/1993, or the Ports Modernization Law, which provided the legal framework applicable to the development and operation of ports and port facilities in Brazil. To improve the applicable legislation, the Brazilian government enacted Law No. 12,815/2013, or the “New Ports Law,” which has been regulated by Decree No. 8,033/2013, recently amended by Decree No. 9,084/2017. Such law revoked the Ports Modernization Law and established a new legal framework for port operations in Brazil. As a result, public ports are governed by the New Ports Law and by specific complementary regulations enacted at the federal level, particularly by the Agência Nacional de Transportes Aquaviários and by the Secretaria Nacional de Portos, or “SNP.” (SNP has been integrated within the structure of the Federal Government’s Transportation, Ports and Civil Aviation Ministry by Federal Law No. 13,341/2016).

Pursuant to the New Ports Law, there is no longer a distinction between third-party and own cargo handled at private port terminals, i.e., the activities carried out in private terminals will be identical to those performed at public terminals with respect to the rendering of services. As a result, public ports are expected to face higher competition from the potential increase in development of operations in private ports. Accordingly, new port lease grants may be carried out by the Brazilian federal government, which may affect inter-and intra-port competition. Finally, Rumo may not be able to meet the minimum cargo volumes provided for in Rumo’s port lease agreements, which may subject it to fines and, upon repeated violations, to the early termination of the relevant grants.

Although the New Ports Law does not retroactively adjust the terms of any concession agreement currently in effect, it is possible that the supplemental regulations provide for such retroactive adjustment (including by means of unilateral requirements from the granting authority). New regulations applicable to port operations in Brazil that modify the terms of Rumo’s grant documents may materially and adversely affect our results of operations.

The loss of Brazilian railway concessions may have a material adverse effect on our business.

Brazilian railway concessions are subject to early termination in certain circumstances, including the Brazilian authorities reassuming control of the service pursuant to applicable law or by the termination of the relevant concession for breach of any underlying contractual agreements, in particular the inadequate provision of rail transportation services provided for in the concession agreements. Pursuant to Federal Law No. 8,987/1995, concession agreements may be terminated as a consequence of: (1) expiration of the contractual term; (2) expropriation of the port concessions in the public interest (i.e., encampação); (3) forfeiture (caducidade); (4) termination; (5) annulment; (6) bankruptcy; or (7) expiration of the concession-holding entity.

Encampação is the seizure of the service by the granting authority during the concession term to the benefit of public interest, by means of a specific authorizing law and after payment of an indemnity. The granting authority may declare the forfeiture of the agreement in the cases in which the concessionaire recurrently defaults on its obligations, or annulment in the cases that the bidding documents for the concession or the concession agreement are tainted by unlawful provisions, or declare penalties, due to total or partial non-performance of the agreement. The granting authority may forfeit the concession when, among other events: (1) the service is being rendered in an inadequate or insufficient manner, according to the norms, criteria, indicators and parameters defining the quality of the service; (2) the concessionaire breaches contractual, regulatory or legal provisions concerning the concession; (3) the concessionaire interrupts the service other than for acts of god or force majeure events; (4) the concessionaire no longer possesses the economic, technical or operational conditions required to adequately render the services under the concession; and (5) the concessionaire does not comply with the penalties imposed for breaches within the established deadlines.

27

Upon termination of a concession, the leased or operated assets revert to the granting authority, and the amount of compensation received may not be sufficient to cover the losses incurred by us as a result of such early termination. In addition, certain creditors may have priority with regards to such compensation.

In addition, pursuant to the terms of Rumo’s concession agreements, the granting authority may intervene in the concession to ensure that the relevant services are being provided as well as to ensure compliance with the applicable contractual clauses and legal and regulatory norms.

An early termination of Rumo’s concession agreement, as well as the imposition upon Rumo of penalties associated with such termination and interventions in our management may have a material impact on Rumo’s operating results and affect our payment capacity and ability to meet our financial obligations.

Rumo may not obtain early renewals of the Rumo Malha Paulista S.A., or “Malha Paulista,” and Rumo Malha Sul S.A., or “Malha Sul,” concession agreements, currently under review by the Brazilian Transportation Authority (Agência Nacional de Transporte Terrestre), or “ANTT,” which may have a material adverse effect on Rumo’s investment plan and growth strategy.

The concession agreements for Malha Paulista and Malha Sul expire in 2028 and 2027, respectively. In September 2015, Rumo filed formal requests with the ANTT for early renewals of such agreements.

In the meantime, Law No. 13,448/2017 was enacted following the conversion into law of Provisional Measure No. 752/2016 which defines the general rules governing extensions of concessions, including early renewals, as well as rebidding of partnership contracts of the federal public administration pursuant to the provisions of Law No. 13,334/2016 in the road, rail and airport sectors. Pursuant to the terms of the new law, the granting authority will perform rebidding if there is a breach of contract or if the concession holders are no longer capable of fulfilling the contractual and financial obligations originally undertaken. In the case of early renewals, rail concession holders must demonstrate provision of adequate services, including compliance with production and safety targets or of safety targets set forth in the applicable contracts, pursuant to the provisions of article 6, paragraph 2 of Law No. 13,448/2017. In addition, contract amendments must contain a timeline for required investments and include measures to discourage potential noncompliance or delay in complying with obligations (such as the annual rebalancing discount and the additional grant payment).

Lastly, early renewals and rebiddings must be submitted to a public consultation by the granting authority. Once the public consultation is completed, the relevant documentation must be deposited with the Brazilian federal accounting court (Tribunal de Contas da União), or “TCU.”

Following the enactment of Law No. 13,448/2017, the early renewal requests relating to Malha Paulista and Malha Sul which are currently being reviewed by the ANTT had to be complemented in order to comply with the newly enacted rules (in particular as regards the requirement under Article 6, paragraph 2 of Law No. 13,448/2017 to demonstrate adequate provision of the services). Rumo currently fulfills these new obligations and expects to successfully complete the early renewal processes of its concessions.

We cannot guarantee that Rumo’s requests for renewals will be successful or that they will occur within the timeframe which we anticipate. In addition, any early renewal may be subject to certain conditions precedent or the applicable concessions may be renewed on terms less favorable than those currently in place. Rumo may also face significant competition from third parties if the granting authority decides to subject our maturing concessions to a rebidding process.

Rumo may incur additional liabilities if it obtains an early renewal of the Rumo Malha Paulista S.A., or “Malha Paulista,” concession agreement, currently under review by the ANTT.

Malha Paulista’s concession agreement is due to expire in 2028. In September 2015, Rumo filed a formal request with the ANTT for early renewal of such concession agreement. The extension request is currently under review by the ANTT. If the ANTT approves the extension request, it is estimated that, in addition to the investment commitments provided for in our business plan, Malha Paulista may incur additional liabilities currently estimated by the ANTT to be in an amount of approximately R$1 billion. Once the value of these liabilities has been confirmed, Rumo may, pursuant to (i) applicable legislation and (ii) clause 6.2 of the draft of the amendment to the Malha Paulista’s concession agreement (the public consultation procedure for which has already been completed by the ANTT), enter into an agreement with the ANTT whereby instead of indemnifying the ANTT for such liabilities, we would be required to invest a substantial amount in our rail networks (both within Malha Paulista and in other parts of our logistics business). The abovementioned amount is currently under discussion with the TCU.

28

Rumo’s Brazilian rail tariffs are subject to a maximum rate established by the Brazilian government.

Under Rumo’s rail network concession agreements, tariffs for our rail freight services are subject to a maximum rate. Maximum tariff rates that Rumo is allowed to charge are adjusted for inflation according to variations in the IGP-DI index (or a substitute index) in accordance with applicable Brazilian law or concession agreements. Currently, tariff adjustments are performed on an annual basis, at different months of the year, depending on the terms of each concession agreement. Additionally, the tariffs Rumo charges for rail freight services on our rail network can be revised upwards or downwards if there is a justified, permanent market and/or costs change that may alter the rail network concession agreements’ economic and financial balance, or as determined by the Brazilian government every five years. The mechanisms for restoring the financial balance are defined in Brazilian law or in the agreements and must be requested by the non-breaching party along with adequate economic evidence. Rumo’s tariffs are currently below the maximum tariff levels allowable under Rumo’s concession agreements. In 2012, the ANTT implemented a review of reference rates that altered the original methodology for defining such rates. The use of revised rate charts could affect Rumo’s capacity to generate revenues, as such review revised most rates downwards and established a cap for Malha Norte, which originally was not subject to a cap. Before Cosan, through its subsidiary Rumo Logística, acquired 100% of the common shares of ALL on April 1, 2015, ALL obtained an injunction suspending the application of such revised rate charts by the ANTT and, therefore, is not subject to them. However, we cannot assure you that in the future tariffs will be set at a level that would permit Rumo to continue to operate profitably.

Rumo may become subject to additional stringent environmental requirements.

In September 2016, the environmental agency of the state of São Paulo (Companhia de Tecnologia de Saneamento Ambiental or “CETESB”) enacted a regulation (Board Decision No. 210/2016/I/C) requiring private ports in the state of São Paulo to comply with more stringent requirements with respect to environmental permits. As a result, Rumo received notifications requiring it to present a regularization plan to CETESB, setting forth how Rumo proposes to comply with these more stringent requirements. This regularization plan was submitted to CETESB on June 12, 2017 and Rumo expects that it will form the basis of an agreement between us and CETESB. Rumo is unable to estimate the amounts it may have to spend in order to fully implement the regularization plan to be presented to CETESB. If these amounts are significant, Rumo’s business, operating results and financial condition could be materially and adversely affected.

We are subject to extensive environmental regulation.

Our business activities in Brazil are subject to extensive laws and regulations concerning environmental protection, which impose on us various environmental obligations, such as environmental licensing requirements, standards for the release of effluents, management of solid waste, protection of certain areas (including Legal Reserve, indigenous areas, quilombolas community areas, conservation units, archeological sites and permanent preservation areas), and the need for special authorizations for the use of water, among others.

The failure to comply with such laws and regulations (including failure to obtain or maintain the relevant environmental permits) may subject the violator to administrative fines, mandatory interruption of activities and criminal sanctions, in addition to the obligation to cure and pay environmental and third-party damage compensation, without any caps. In addition, Brazilian environmental law adopts a joint and several and strict liability system for environmental damages, which makes the polluter liable regardless of fault or intentional misconduct and would make us jointly and severally liable for the obligations of our producers or off-takers. If we become subject to environmental liabilities, any costs we may incur to rectify possible environmental damage would lead to a reduction in the financial resources which would otherwise remain at our disposal for current or future strategic investment, thus causing an adverse impact on us.

As environmental laws and their enforcement become increasingly stringent, our expenses for complying with environmental requirements are likely to increase in the future. Furthermore, the possible implementation of new regulations, changes in existing regulations or the adoption of other measures could cause the amount and frequency of our expenditures on environmental preservation to vary significantly compared to present estimates or historical costs. Any unplanned future expenses could force us to reduce or forego strategic investments and as a result could materially and adversely affect us.

The occurrence of environmental damage may lead to the need to make significant financial resources available for both containment and repair of these damages. The occurrence of such events may also lead to a disruption in production due to intervention by government agencies. In either case, financial and/or image impacts may be significant. In addition, the creation of new regulations may lead to the need for greater expenses with environmental preservation. Furthermore, extensive environmental regulation can also lead to delays in the implementation of new projects as bureaucratic procedures for obtaining environmental licenses from various government agencies may take considerable time.

29

The realization of any of these risks may have a material adverse effect on our business, results of operations or financial condition.

We cannot predict the outcome of an investigation into the conduct of former employees of ALL prior to its acquisition by Rumo.

During the course of 2016, Rumo became aware of certain press reports alleging that improper payments to government officials were made by former employees of ALL (prior to being acquired by Rumo) in connection with an investment by Fundo de Investimento do Fundo de Garantia do Tempo de Serviço, or “FI-FGTS,” in Rumo’s indirect subsidiary Brado Logística and in ALL. As a result of these allegations, Rumo has engaged external legal counsel and consultants to conduct an internal investigation. The report of the investigation was submitted to the Federal Prosecutor’s Office (without being made available to the Company, in accordance with the terms of the engagement). At this time, we can neither predict the outcome of the internal investigation, the consequences of any findings or any measures that may be taken by local authorities, any of which may have a material adverse effect on Rumo.

Rumo may not have access to new financing on favorable conditions to meet its capital needs and fulfill its financial obligations.

Rumo relies on obtaining financing and refinancing of existing loans, particularly from BNDES, in order to operate its business, implement its strategy and grow its business. Rumo needs bank guarantees to obtain credit facilities from both BNDES and banks, and typically needs insurance guarantees in order to participate in court proceedings to which it is a party. Recent disruptions in the global credit markets and their effect on the global and Brazilian economies could affect Rumo’s ability to raise capital and materially and adversely affect Rumo’s business.

Substantial volatility in the global capital markets, unavailability of financing in the global capital markets at reasonable rates and credit market disruptions have had a significant negative impact on financial markets, as well as on the global and domestic economies. In particular, the cost of financing in the global debt markets has increased substantially, greatly restricting the availability of funds in such markets. Further, volatility in the markets has led to increased costs for obtaining financing in the credit markets, as many creditors have raised interest rates, adopted more rigorous loan policies, reduced volume and, in some cases, ceased offering financing to borrowers on reasonable terms.

If Rumo is unable to obtain new financing or to refinance existing loans when necessary, or obtain or renew insurance guarantees on reasonable terms or at all, Rumo may not be able to comply with its financial obligations or explore business opportunities. This would have a material adverse effect on Rumo’s business, financial condition and results of operations.

Rumo may not be successful in reducing operating costs and increasing operating efficiencies.

Rumo may not be able to achieve expected cost savings, which rely on several factors such as rail track prices, railroad ties, fuel, iron, engineering and other resources required for our operations. Given the competitive markets in which Rumo operates, it is likely that it will not be able to pass increases in costs of materials onto the price of our services (including as a result of limits applying to our tariffs), which would materially and adversely affect its financial performance.

Rumo may not have sufficient funds to invest in technology, which may adversely affect Rumo’s ability to increase its rail transportation capacity and reduce accidents.

The development and implementation of new technologies may result in a significant reduction in the cost of logistics services and a reduction in accidents. We cannot predict when new technologies may become available, the rate of acceptance of new technologies by competitors or the costs associated with such new technologies. Rumo may not have enough funds to keep up with advances in technology, which could reduce demand for the logistics services Rumo provides and affect Rumo’s capacity to reduce accidents in its activities.

The exercise of an option granted under the shareholders’ agreement of one of Rumo’s subsidiaries, Brado Logística, may have a material adverse effect on Rumo’s financial condition or result in a dilution of Rumo’s shareholders’ equity interest.

Fundo de Investimento do Fundo de Garantia do Tempo de Serviço, or “FI-FGTS,” Logística Brasil — Fundo de Investimento em Participações, or “FIP – BRZ,” Deminvest Empreendimentos e Participações S.A, or “Deminvest,” Markinvest Gestão de Participações Ltda., or “Markinvest” and Brado Holding S.A., or “Brado Holding,” are parties to a shareholders’ agreement governing the investment in Brado Logística, Rumo’s subsidiary active in the intermodal container logistics sector, or the “Brado Shareholders’ Agreement.” Markinvest, FIP – BRZ and Deminvest are jointly referred to as the “Original Shareholders.” Brado Holding, FI-FGTS and the Original Shareholders are jointly referred to as the “Brado Shareholders.”

30

The Brado Shareholders’ Agreement provides that, to the extent the initial public offering of Brado LP has not occurred prior to March 31, 2014, the Brado Shareholders are entitled to swap the totality of their shares in Brado Logística for, at the discretion of Brado Holding: (1) shares as provided for in the Brado Shareholders’ Agreement, or (2) an amount corresponding to the market value of such shares. The exchange ratio would be based on fair market value. If the Brado Shareholders do not reach consensus on the appraisal thereof, the fair market value would be based on independent appraisals carried out as provided for in the Brado Shareholders’ Agreement.

The option described above became exercisable on April 1, 2014 and was exercised on each of April 20 and 23, 2015. There is an ongoing confidential arbitration proceeding against Rumo relating to the appraisal reports prepared by financial institutions appointed pursuant to the shareholders’ agreement of Brado Logística and the type of consideration (money or shares) due as a result of the exercise of the option.

In addition, the exercise of the option by FI-FGTS may occur between the fifth and the seventh anniversary of the date of signing of the Brado Shareholders’ Agreement (which was August 5, 2013). FI-FGTS will lose the right to exercise its option if the aforementioned initial public offering is undertaken (even if such initial public offering is undertaken after the aforementioned dates).

The exercise of the option may result in: (1) disbursement of material amounts by Rumo, which may adversely affect Rumo’s results of operations and financial condition; or (2) the issuance of new shares by Rumo in a quantity which may dilute the equity interests held by Rumo’s shareholders.

Downturns in certain cyclical market sectors in which Rumo’s customers operate could have a material adverse effect on Rumo’s business.

The transportation and logistics industries are highly cyclical, generally tracking the cycles of the world economy. Accordingly, the transportation industry is affected by macroeconomic conditions and by various factors within each particular industry that may influence operating results. Some of Rumo’s customers do business in highly cyclical markets, including the oil and gas and agricultural sectors.

Soybean harvests generally occur between January and May, corn harvests (mainly for export) generally occur between April and July and sugar harvests generally occur between March and November. For this reason, Rumo typically transports larger volumes of goods in the second and third quarters of each year and lower volumes in the “off season” (i.e., the first and fourth quarters of each year).

Any downturn in these industries may have a material adverse effect on Rumo’s business, results of operations and financial condition. In addition, some of the products Rumo transports have shown a historical pattern of price cyclicality, which has typically been influenced by the general economic environment, industry capacity and demand. We cannot assure you that prices and demand for these products will not decline in the future, adversely affecting those industries and, in turn, Rumo’s business, results of operations and financial condition.

Rumo operates in a competitive industry, and if it is unable to adequately address factors that may adversely affect its revenue and costs, Rumo’s business could suffer.

An increase in competition may reduce our revenues and result in smaller profit margins or the loss of market share. Our business, financial condition and results of operations may be adversely affected if we are not able to adequately compete in the market.

Competition in the transportation services industry is intense and includes:

• competition with other transportation modes, such as road freight;

• competition with alternative export options for agricultural products through other ports (particularly in the northern region of Brazil) to the detriment of the ports of Santos (state of São Paulo), Paranaguá (state of Paraná) and São Francisco do Sul (state of Santa Catarina);

• dependence on operating quality and port and terminal capacity;

• the limitations established by the maximum tariffs established by the ANTT;

31

• a reduction in road tariffs, particularly during times of declining growth rates in the economy or low demand from agricultural producers, which may limit Rumo’s ability to maintain or increase rates, operating margins or growth of its business; and

• establishment of cooperative relationships by Rumo’s competitors to increase their ability to address shipper needs.

Rumo’s main competitors are companies in the truck transportation business, which has historically been the main cargo transportation mode in Brazil. According to the CNT, trucks transported 61% of Brazil’s production in 2016, while only 21% of that production was transported by rail and 14% was transported on waterways, which includes coastal shipping. Although Rumo is expanding our intermodal services via truck transportation, any new measures by the Brazilian government that lower costs for road transportation, such as cheaper toll fares or permanent suspension of the toll-road concession program, may limit Rumo’s growth prospects.

New measures by the Brazilian government that benefit or reduce costs for road transportation, such as cheaper toll fares or permanent suspension of the toll-road concession program, may limit our growth prospects.

Increased competition may lead to decreases in Rumo’s revenues, smaller profit margins or loss of market share. If Rumo is unable to address any of these adequately, it may adversely impact Rumo’s business, financial condition and results of operations.

Rumo operates in a regulated environment, and measures taken by public authorities may impact Rumo’s activities.

The rail services which Rumo provides are regulated and supervised by the Brazilian government and in particular by the Brazilian Ministry of Transportation, Ports and Civil Aviation as well as the ANTT. The ANTT regulates various aspects of the business of companies active in the Brazilian rail sector, including with regards to requirements for investments, expenses, determination of revenue and the setting of tariffs in order to guarantee regularity, continuity, efficiency, safety and affordability. These activities are intensely regulated through laws, decrees, provisional measures, ordnances, resolutions and other regulatory and legislative actions. Changes to legislation or regulation relating to the rail sector may adversely affect Rumo’s business, financial results and operating results.

In addition, Rumo’s railroad concession agreements have been entered into with the Brazilian Ministry of Transportation (acting as granting authority when the grants took place), later substituted by the ANTT after the enactment of Federal Law No. 10,233/2001. Rumo’s operations take place in a highly regulated environment because concessions agreements are administrative contracts. Such contracts are therefore subject to public law, which gives the granting authority the right to: (1) amend the contracts unilaterally when in the public interest (while respecting the rights under the contract); (2) rescind the contracts unilaterally in the instances provided for in Law No. 8,666/1993; (3) supervise the execution of the contracts; and (4) impose sanctions in the case of partial or complete non-compliance with the adjustment (among other instances).

Therefore, notwithstanding the concessionaire’s right to maintain the financial balance of the concession agreement, actions taken by the public administration in general may affect the services rendered by Rumo. For example, if (1) new obligations are imposed; (2) additional investments not originally provided for in the concession agreements are required as a result of unilateral measures provided for in the statute or through the creation of new regulations by the ANTT; and (3) the scope of the concession agreements is reduced or certain actions taken by us are rejected or not given effect (such as anticipated concession renewals, extensions of grants in force or extensions under conditions not favorable to us), Rumo’s economic and financial condition and operating results may be adversely affected.

We cannot predict which actions the Brazilian government will take in the future and how such actions will affect Rumo’s operating results. If Rumo is required to conduct its business in a manner substantially different from that contemplated in Rumo’s business plan, Rumo’s financial and operating results may be adversely affected.

We are exposed to the possibility of losses related to natural disasters, catastrophes, accidents, fire and other events not in our control, which may have a material adverse effect on our financial performance.

Our operations are subject to certain risks that affect our properties, facilities, permanent passageways, rail banks and inventory, including, among others, fire, which may destroy machinery, equipment and facilities, as well as client cargo being transported. Fires, explosions, fuel leaks and other flammable products as well as other environmental events, cargo loss or damage, railroad, cargo loading and unloading terminal, accidents, business interruptions due to political events as well as labor claims, demonstrations by social and/or environmental groups or associations, strikes (of our own employees or of those linked to entities with which we have a relationship, such as port operators), adverse weather conditions and natural disasters, such as floods, may result in the loss of revenues, assumption of liabilities or cost increases. Moreover, our operations may be periodically affected by crop shortfalls, landslides and other natural disasters.

32

Our transportation and handling of cargo exposes us to risks of catastrophes, mechanical and electrical failures, collisions and loss of assets. A portion of our freight activities involves petroleum products and other flammable materials, and the presence of such products may aggravate the effects of any catastrophe.

Because our insurance does not cover all potential risks and losses we may incur, the occurrence of a natural disaster of large proportions, catastrophes, mechanical failures, loss of assets or any other of the events referred to above, and any resulting damage to our business, may have a material adverse effect on our business, operating results and financial condition, including as a result of civil, administrative and/or criminal sanctions relating to environmental liability (including civil, administrative and/or criminal sanctions of such nature imposed on our management).

We are exposed to credit and other counterparty risks of our customers in the ordinary course of our business.

We have various credit terms with virtually all of our wholesale and retail industrial customers, and our customers have varying degrees of creditworthiness which exposes us to the risk of nonpayment or other default under our contracts and other arrangements with them. In the event that a significant number of material customers default on their payment obligations to us, our financial condition, results of operations or cash flows could be materially and adversely affected.

Our inability to post judicial collateral or provide guarantees in pending legal or administrative proceedings could have a material adverse effect on our business, financial condition and results of operations.

We may not have sufficient funds to post collateral or provide guarantees in judicial or administrative proceedings involving substantial amounts. Even if we do not post such collateral or provide guarantees, we will be liable for paying any amounts due pursuant to any unfavorable outcomes in legal proceedings. We cannot assure you that, if we cannot make such payments, our assets, including financial assets, will not be attached, or that we will be able to obtain tax good standing certificates, all of which may have a material adverse effect on our business, financial condition and results of operations.

We are subject to anti-corruption, anti-bribery, anti-money laundering and other international trade laws and regulations.

We are subject to anti-corruption, anti-bribery, anti-money laundering and other international trade laws and regulations. We are required to comply with the laws and regulations of Brazil and various jurisdictions where we conduct operations. In particular, we are subject to the Brazilian Anti-corruption Law nº 12.846, to the U.S. Foreign Corrupt Practices Act of 1977, or the “FCPA,” to the United Kingdom Bribery Act of 2010, as well as economic sanction programs, including those administered by the United Nations, the European Union and the United States, including the U.S. Treasury Department’s Office of Foreign Assets Control, or “OFAC.” The FCPA prohibits providing anything of value to foreign officials for the purposes of obtaining or retaining business or securing any improper business advantage. As part of our business, we may deal with entities and employees which are considered foreign officials for purposes of the FCPA. In addition, economic sanctions programs restrict our dealings with certain sanctioned countries, individuals and entities. Although we have internal policies and procedures designed to ensure compliance with applicable anti-fraud, anti-bribery and anti-corruption laws and sanctions regulations, potential violations of anti-corruption laws have been identified on occasion as part of our compliance and internal control processes. When such issues arise, we attempt to act promptly to learn relevant facts, conduct appropriate due diligence, and take any appropriate remedial action to address the risk. Given the size of our operations and the complexity of the production chain, there can be no assurance that our internal policies and procedures will be sufficient to prevent or detect all inappropriate practices, fraud or violations of law by our employees, directors, officers, partners, agents and service providers or that such persons will not take actions in violation of our policies and procedures (or otherwise in violation of the relevant anti-corruption laws and sanctions regulations) for which we or they may be ultimately held responsible. Violations of anti-bribery and anti-corruption laws and sanctions regulations could have a material adverse effect on our business, reputation, results of operations and financial condition. In addition, we may be subject to one or more enforcement actions, investigations and proceedings by authorities for alleged infringements of these laws. These proceedings may result in penalties, fines, sanctions or other forms of liability and could have a material adverse effect on our reputation, business, financial condition and results of operations.

33

Funding, especially on terms acceptable to us, may not be available to meet our financial obligations and future capital needs.

We rely on obtaining financing and refinancing of existing loans in order to operate our business, implement our strategy and grow our business. We need bank guarantees to obtain credit facilities and we typically need insurance guarantees in order to participate in court proceedings to which we are a party.

If we are unable to obtain new financing or to refinance existing loans when necessary, or obtain or renew insurance guarantees on reasonable terms or at all, we may not be able to comply with our financial obligations or explore business opportunities, and responding to competitive pressures may become challenging. This would have a material adverse effect on our business, financial condition and results of operations.

We operate in industry sectors that require significant financial resources that will require access to the capital markets and bank financing in significant volumes to meet our investment objectives.

We obtain funds for our activities through loans from financial institutions, domestic and foreign lenders, and through access to the capital markets. Our ability to obtain funding to finance our growth or operate our business depends on several factors, including our level of indebtedness and market conditions. Global market and economic conditions have been, and continue to be, disruptive and volatile. The debt capital markets have been impacted by significant write-offs in the financial services sector and the re-pricing of credit risk, sovereign defaults, political and economic developments in and affecting Brazil such as the “Lava Jato” scandal, among other things. These events have negatively affected general economic conditions, especially in the period from 2014 to the first quarter of 2017. During that period, the cost of raising money in the debt capital markets has increased substantially while the availability of funds from those markets for Brazilian companies has diminished significantly. Also, as a result of concerns about the stability of financial markets generally and the solvency of counterparties specifically, the cost of obtaining money from the credit markets has increased as many lenders and institutional investors have increased interest rates, enacted tighter lending standards and reduced and, in some cases, ceased to provide funding to borrowers on commercially reasonable terms or at all. Our failure to obtain the necessary resources on reasonable terms may adversely affect our investment strategy. If we decide to increase our debt levels, we may be subject to risks, including our inability to pay outstanding debt, which may adversely affect our financial condition.

In addition, in connection with any new indebtedness we incur, we may be required to meet certain covenants in our financing arrangements, such as maintaining financial ratios, and may be subject to restrictions on our ability to incur new debt or make new investments. A breach of these covenants may result in a mandatory prepayment or acceleration of the maturity of our outstanding debt. In the event of a prepayment or acceleration, our assets and cash flow might not be sufficient to pay the full amount due, which would have a material adverse effect on our financial condition.

Our debt level could adversely affect our financial health and prevent us from fulfilling our debt obligations, which would reduce our ability to raise capital to finance our investments and operations and would adversely impact our ability to recover from economic changes.

Our debt level and the composition of our debt could, among other things: (1) require us to reserve a substantial part of our operational cash flows to pay principal and interest on our debt, which will reduce the availability of our cash flow to fund working capital, capital expenditures, acquisitions and investments; (2) limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate; (3) limit our ability to borrow additional funds, obtain bank guarantees or collateral insurance and generally increase our borrowing costs; and (4) place us at a competitive disadvantage compared to our competitors that have less debt.

Any of the aforementioned developments could have a material adverse effect on us, our financial condition and our results of operations.

We may be unable to comply with restrictive covenants under our financing agreements.

We are subject to certain restrictive covenants based on certain financial and non-financial indicators which are set forth in the majority of the indebtedness and finance agreements to which we are a party. The majority of such covenants relate to requirements to comply with certain pre-determined levels of leverage.

34

Any failure by us to comply with the restrictive covenants in our credit agreements as a result of adverse conditions in our business environment may trigger the acceleration of part of our indebtedness, limit our access to new credit facilities as well as adversely affect our business and results of operations.

We may raise additional capital in the future for strategic partnerships or by issuing securities, which may result in a potential dilution of your equity interest.

We are constantly analyzing alternatives and considering the possibility of entering into strategic partnerships, disposing of assets, raising additional capital through a public or private issuance of shares and/or securities convertible into or exchangeable for shares. Any strategic partnership, issuance or placement of shares and/or securities convertible into or exchangeable for shares may affect the market price of our shares and could result in dilution of your equity interest.

Our insurance coverage may be inadequate to cover all losses and/or liabilities that may be incurred in our operations.

Our operations are subject to a number of hazards and risks. We maintain insurance at levels that are customary in our industry to protect against these liabilities; however, our insurance may not be adequate to cover all losses or liabilities that might be incurred in our operations.

For example, we do not maintain coverage for business interruptions of any nature for our Brazilian operations, including business interruptions caused by labor disruptions. If, for instance, our workers were to strike, the resulting work stoppages could have a material and adverse effect on us. Similarly, we do not insure most of our assets against war or sabotage. Therefore, an attack or an operational incident causing an interruption of our business could have a material and adverse effect on our financial condition or results of operations.

Moreover, we will be subject to the risk that we may not be able to maintain or obtain insurance of the type and amount desired at reasonable rates. If we were to incur a significant liability for which we were not fully insured, it could have a materially adverse effect on our business, financial condition and results of operations.

Any failure relating to our strategic partnerships may result in additional financial or performance obligations by us, which would reduce our profitability.

We may enter into strategic partnerships, joint ventures, combinations, alliances and collaborations, including, among other things, partnerships with our customers. The success of these and other partnerships depends, in part, on the satisfactory performance of our and our partners’ obligations.

If we or our partners do not satisfactorily perform such obligations, our strategic partnerships may fail to perform as expected or to deliver the agreed services. Should this occur, we may be required to make additional investments and provide additional services to guarantee the adequate performance and delivery of the agreed services, or terminate such partnerships prior to their stated maturity. The performance by us of additional obligations with respect to our strategic partnerships may result in the reduction of our profits and material losses to us.

Likewise, the failure of our strategic partners to fulfill their obligations under our partnership agreements may have a material adverse effect on such partnerships. In addition, the failure to reach an agreement as to certain matters may result in deadlock pursuant to certain of the shareholders’ and other agreements governing our strategic partnerships.

Strategic partnerships are essential to the continuity of our operations and our growth. If we fail to maintain our existing partnerships or identify new partnerships, our business, financial condition and results of operations may be materially and adversely affected.

We are highly dependent on our chairman and other members of our management to develop and implement our strategy and to oversee our operations.

We are dependent upon our chairman and controlling shareholder, other members of senior management and certain members of our board of directors, especially with respect to business planning, strategy and operations. If any of these key members of our management leaves our Company, our business and financial performance may be negatively affected. Our business is particularly dependent on our chairman, who is also our controlling shareholder. We currently do not carry any key man insurance.

35

We are indirectly controlled by a single individual who has the power to control us.

Our controlling shareholder and chairman has the power to indirectly control us, including the power to:

• elect a majority of our directors and appoint our executive officers, set our management policies and exercise overall control over our Company and subsidiaries;

• agree to sell or otherwise transfer his controlling stake in our Company; and

• determine the outcome of substantially all actions requiring shareholder approval, including transactions with related parties, corporate reorganizations, acquisitions and dispositions of assets, and dividends.

Currently, because of the share capital structure of our parent company Cosan Limited, our controlling shareholder is able to control substantially all matters submitted to our shareholders for a vote or approval even if the controlling shareholder comes to own less than 50% of our issued and outstanding share capital. The concentrated control will limit your ability to influence corporate matters and, consequently, we may take actions that our shareholders do not view as beneficial. Moreover, Cosan’s controlling shareholder may make decisions that are contrary to the interests of their other shareholders, and diverge from those minority shareholders. These may include actions to conduct acquisitions, divest assets, engage in new business partnerships and engage in new financings or similar operations. As a result, the market price of our shares could be adversely affected.

We operate in industry sectors that require significant financial resources that will require access to the capital markets and bank financing in significant volumes to meet our investment objectives.

We obtain funds for our activities through loans from financial institutions, domestic and foreign lenders, and through access to the capital markets. Our ability to obtain funding to finance our growth or operate our business depends on several factors, including our level of indebtedness and market conditions. Global market and economic conditions have been, and continue to be, disruptive and volatile. The debt capital markets have been impacted by significant write-offs in the financial services sector and the re-pricing of credit risk, sovereign defaults, political and economic developments in and affecting Brazil such as the “Lava Jato” scandal, among other things. These events have negatively affected general economic conditions. In particular, the cost of raising money in the debt capital markets has increased substantially while the availability of funds from those markets for Brazilian companies has diminished significantly. Also, as a result of concerns about the stability of financial markets generally and the solvency of counterparties specifically, the cost of obtaining money from the credit markets has increased as many lenders and institutional investors have increased interest rates, enacted tighter lending standards and reduced and, in some cases, ceased to provide funding to borrowers on commercially reasonable terms or at all. Our failure to obtain the necessary resources on reasonable terms may adversely affect our investment strategy.

A breach of these covenants may result in a mandatory prepayment or acceleration of the maturity of our outstanding debt. In the event of a prepayment or acceleration, our assets and cash flow might not be sufficient to pay the full amount due, which would have a material adverse effect on our financial condition.

36

Failure to fulfill the conditions precedent to the closing of the acquisition of Shell’s downstream business in Argentina may have a material adverse effect on Raízen Combustíveis.

On April 24, 2018, Raízen Combustíveis entered into an agreement with Shell Overseas Investments B.V. and B. V. Dordtsche Petroleum Maatschappij to acquire Shell’s downstream business in Argentina through the acquisition of the shares of Shell Compañía Argentina de Petróleo S.A. and Energina Compañía Argentina de Petróleo S.A., or “Shell Argentina.” The closing of the transaction is subject to certain customary closing conditions, including (1) a corporate reorganization of the target group of companies, which includes a carve-out of the upstream (exploration and production) business of Shell in Argentina, and (2) receipt of regulatory approvals (however, receipt of antitrust approval is not a condition to completion). It is currently expected that these conditions precedent will be fulfilled by the end of 2019.

In addition, the purchase agreement relating to the acquisition of Shell Argentina provides that Raízen Combustíveis may, subject to certain conditions, choose not to proceed with the closing of the acquisition if the results of its due diligence of certain documents and other matters provided to Raízen Combustíveis by the seller following the signing of the purchase agreement are not satisfactory.

Further, the purchase agreement provides that if the conditions precedent to closing are not fulfilled by April 24, 2019, as a result of Raízen Combustíveis’s actions or omissions, the transaction will not close and Raízen Combustíveis will forfeit its initial upfront payment of U.S.$100 million.

We cannot assure you that the conditions precedent for the closing of the acquisition of Shell Argentina will be fully met. Failure to fulfill such conditions may adversely affect Raízen Combustíveis.

Raízen Combustíveis may not be able to successfully integrate the operations of Shell Argentina and faces other risks associated with the acquisition.

If the acquisition of Shell Argentina by Raízen Combustíveis is completed, Raízen Combustíveis may not be able to successfully integrate Shell Argentina into its business, or successfully implement appropriate operational, financial or administrative systems and controls to achieve the benefits that we expect to result from the acquisition of Shell Argentina. The risks faced by Raízen Combustíveis include but are not limited to: (1) failure of Shell Argentina to achieve expected results; (2) inability to retain key personnel of Shell Argentina; (3) failure to successfully migrate Shell Argentina’s current customer and supplier relationships to the business as acquired by us; and (4) possible inability to achieve expected synergies or economies of scale. In addition, the business of Shell Argentina could cause interruption of, or loss of momentum in, the activities of the existing business of Raízen Combustíveis. The diversion of our management’s attention and any delays or difficulties encountered in connection with the integration of Shell Argentina could adversely affect the business, results of operations or prospects of Raízen Combustíveis.

The acquisition of Shell Argentina also exposes Raízen Combustíveis to the risk that it will inherit pre-existing business, labor, environmental or other issues which may result in temporary shutdowns, labor disputes, obligations to compensate third parties for environmental damage or repair environmental damage or which may otherwise have an adverse effect on Raízen Combustíveis if not managed properly.

In addition, the acquisition of Shell Argentina may expose Raízen Combustíveis to successor liability relating to certain prior actions of Shell Argentina and its management or certain contingent liabilities incurred prior to its involvement. It will also expose Raízen Combustíveis to certain liabilities associated with ongoing operations (including, without limitation, environmental liabilities), especially to the extent that Raízen Combustíveis is unable to adequately and safely manage such acquired operations. Also, undisclosed liabilities from the acquisition of Shell Argentina may harm the financial condition and operating results of Raízen Combustíveis.

Risks Related to Our Common Shares

We are a Bermuda company, and it may be difficult for you to enforce judgments against us or our directors and executive officers.

We are a Bermuda exempted company, so that the rights of holders of our shares will be governed by Bermuda law and our bye-laws. The rights of shareholders under Bermuda law may differ from the rights of shareholders of companies incorporated in other jurisdictions. All of our directors and some of the experts referred to in this annual report are not citizens or residents of the United States, and all of our assets are located outside the United States. As a result, it may be difficult for investors to effect service of process on those persons in the United States or to enforce judgments obtained in U.S. courts against us or those persons based on the civil liability provisions of the U.S. federal or state securities laws. We have been advised by our Bermuda counsel, ASW Law Limited, that uncertainty exists as to whether courts in Bermuda will enforce judgments obtained in other jurisdictions, including the United States, against us or our directors or officers under the securities laws of those jurisdictions or entertain actions in Bermuda against us or our directors or officers under the securities laws of other jurisdictions. The United States and Bermuda do not currently have a treaty providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not based solely on U.S. federal or state securities laws, may not necessarily be enforceable in Bermuda.

Bermuda law differs from the laws in effect in the United States and Brazil and may afford less protection to shareholders.

Our shareholders may have more difficulty protecting their interests than shareholders of a company incorporated in the United States or Brazil. As a Bermuda company, we are governed by the Companies Act 1981. The Companies Act 1981 differs in material respects from laws generally applicable to U.S. or Brazilian corporations and their shareholders, including the provisions relating to interested directors, amalgamations, takeovers, shareholder lawsuits and indemnification of directors.

Under Bermuda law, directors and officers of a company generally owe fiduciary duties to the company and not to individual shareholders. Class actions and derivative actions are generally not available to shareholders under Bermuda law. The Bermuda courts may, however, in certain circumstances permit a shareholder to commence an action in the name of a company to remedy a wrong to the company where the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company’s memorandum of association or bye-laws. Consideration would be given by a Bermuda court to acts that are alleged to constitute a fraud against the minority shareholders or, for example, where an act requires the approval of a greater percentage of the company’s shareholders than that which actually approved it. The Companies Act 1981 imposes a duty on directors and officers to act honestly and in good faith with a view to the best interests of the company and to exercise the care and skill that a reasonably prudent person would exercise in comparable circumstances. Directors of a Bermuda company have a duty to avoid conflicts of interest. However, if a director discloses a direct or indirect interest in any contract or arrangement with us as required by Bermuda law, our bye-laws provide that such director is entitled to be counted for quorum purposes, but may not vote in respect of any such contract or arrangement in which he or she is interested. In addition, the rights of our shareholders and the fiduciary responsibilities of our directors under the Companies Act 1981 are not as clearly established as under statutes or judicial precedent in jurisdictions in the United States, particularly in the State of Delaware.

Provisions in our bye-laws may discourage takeovers, which could affect the return on the investment of our shareholders.

Our bye-laws contain provisions that could make it more difficult for a third party to acquire us without the consent of our board of directors. These provisions provide, among other things, for:

• a classified board of directors with staggered three-year terms;

• restrictions on the time period in which directors may be nominated;

• the affirmative vote of a majority of our directors in office and the resolution of the shareholders passed by a majority of votes cast at a general meeting or, if not approved by a majority of the directors in office, the resolution of the shareholders at a general meeting passed by 66 and 2/3% of all votes attaching to all shares then in issue for amalgamation and other business combination transactions; and

• the tag-along rights described under “Item 10. Additional Information—B. Memorandum and By-laws—Tag-along Rights.”

38

These bye-law’s provisions could deter a third party from seeking to acquire us, even if the third party’s offer may be considered beneficial by many shareholders.

As a holding company, we may face limitations on our ability to receive distributions from our subsidiaries.

We conduct all of our operations through subsidiaries and are dependent upon dividends or other intercompany transfers of funds from our subsidiaries to meet our obligations. For example, Brazilian law permits the Brazilian government to impose temporary restrictions on conversions of Brazilian currency into foreign currencies and on remittances to foreign investors of proceeds from their investments in Brazil, whenever there is a serious imbalance in Brazil’s balance of payments or there are reasons to expect a pending serious imbalance. The Brazilian government last imposed remittance restrictions for approximately six months in 1989 and early 1990. The Brazilian government may take similar measures in the future. Any imposition of restrictions on conversions and remittances could hinder or prevent us from converting into U.S. dollars or other foreign currencies and remitting abroad dividends, distributions or the proceeds from any sale in Brazil of common shares of our Brazilian subsidiaries. We currently conduct all of our operations through our principal Brazilian subsidiaries, Cosan S.A. and Cosan Logistica. As a result, any imposition of exchange controls restrictions could reduce the market prices of the class A common shares.

Our bye-laws restrict shareholders from bringing legal action against our directors and officers and also provide our directors and officers with indemnification from their actions and omissions, although such indemnification for liabilities under the Securities Act is unenforceable in the United States.

Our bye-laws contain a broad waiver by our shareholders of any claim or right of action, both individually and on our behalf, against any of our officers or directors. The waiver applies to any action taken by an officer or director, or the failure of an officer or director to take any action, in the performance of his or her duties, except with respect to any matter involving any fraud or dishonesty on the part of the officer or director. This waiver limits the right of shareholders to assert claims against our officers and directors unless the act or failure to act involves fraud or dishonesty. Our bye-laws also indemnify our directors and officers in respect of their actions and omissions, except in respect of their fraud or dishonesty. The indemnification provided in our bye-laws is not exclusive of other indemnification rights to which a director or officer may be entitled, provided these rights do not extend to his or her fraud or dishonesty. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we understand that, in the opinion of the staff of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable in the United States.

The sale or issuance of a significant number of our common shares may adversely affect the market value of our class A common shares.

The sale of a significant number of our common shares, or the perception that such a sale could occur, may adversely affect the market price of our class A common shares. We have an authorized share capital of 1,000,000,000 class A common shares and 188,886,360 class B common shares, of which 146,867,137 class A common shares are issued and outstanding and 96,332,044 class B series 1 common shares are issued and outstanding as of December 31, 2017. Our bye-laws establish that our board of directors is authorized to issue any of our authorized, but unissued share capital. Our shareholders at a shareholders general meeting may authorize the increase of our authorized share capital. As a result, we will be able to issue a substantial number of new shares after the lock-up period, which, if we decided to do so, could dilute the participation of our shareholders in our share capital.

Actual dividends paid on our shares may not be consistent with the dividend policy adopted by our board of directors.

Our board of directors has a dividend policy that provides, subject to Bermuda law, for the payment of dividends to shareholders equal to approximately 25% of our annual consolidated net income (as calculated in accordance with IFRS as issued by IASB). Our board of directors may, in its discretion and for any reason, amend or repeal this dividend policy. Our board of directors may decrease the level of dividends provided for in this dividend policy or entirely discontinue the payment of dividends. Future dividends with respect to our common shares, if any, will depend on, among other things, our results of operations, cash requirements, financial condition, distribution of dividends made by our subsidiaries, contractual restrictions, business opportunities, provisions of applicable law and other factors that our board of directors may deem relevant.

39

To the extent we pay dividends to our shareholders, we will have less capital available to meet our future liquidity needs.

Our business strategy contemplates substantial growth over the next several years, and we expect that such growth will require considerable liquidity. To the extent that we pay dividends in accordance with our dividend policy, the amounts distributed to our shareholders will not be available to us to fund future growth and meet our other liquidity needs.

We may require additional funds in the future, which may not be available or which may result in dilution of the interests of shareholders in our company.

We may need to issue debt or equity securities in order to obtain additional public or private financing. The securities that we issue may have rights, preferences and privileges senior to those of our shares. If we decide to raise additional capital through an offering of common shares, the participation of our shareholders in our share capital may be diluted. Moreover, additional funding that may be required in the future may not be available under favorable terms.

The price of our class A common shares is subject to volatility.

The market price of our class A common shares could be subject to significant fluctuations due to various factors, including actual or anticipated fluctuations in our financial performance, losses of key personnel, economic downturns, political events in Brazil or other jurisdictions in which we operate, developments affecting the ethanol and sugar industries, changes in financial estimates by securities analysts, the introduction of new products or technologies by us or our competitors, or our failure to meet expectations of analysts or investors.

Risks Related to Brazil

Historically, the Brazilian government has influenced and continues to influence the economy in the country, which may negatively affect our business and financial performance.

Political and economic conditions directly affect our business and can result in a material adverse effect on our operations and financial condition. Macroeconomic policies imposed by the government can have significant impacts on Brazilian companies, including Cosan, Rumo and Comgás, as well as market conditions and securities prices in Brazil.

The Brazilian economy has been characterized by frequent and occasionally extensive intervention by the Brazilian government and unstable economic cycles. The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the course of Brazil’s economy. The Brazilian government’s actions to control inflation have at times involved setting wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports into Brazil. For example, on August 31, 2016, Brazil’s Senate removed President Dilma Rousseff from office for infringing budgetary laws. Michel Temer, the former Vice President, who has run Brazil since Ms. Rousseff’s suspension in May, was sworn in by the Senate to serve out the remainder of the presidential term until 2018. However, the resolution of the political and economic crisis in Brazil still depends on the outcome of the “Lava Jato” investigation and approval of reforms that are expected to be promoted by the new president. We cannot predict which policies Mr. Temer may adopt or change during his mandate or the effect that any such policies might have on our business and on the Brazilian economy. Any such new policies or changes to current policies may have a material adverse effect on our business, results of operations and financial condition.

Our business, financial performance and prospects, as well as the market prices of our shares, may be adversely affected by, among others, the following factors:

• inflation;

• exchange rate movements;

• exchange rate control policies;

40

• interest rate fluctuations;

• liquidity available in the domestic capital, credit and financial markets;

• expansion or contraction of the Brazilian economy, as measured by rates of growth in GDP;

• oil and gas sector regulations, including price policies;

• ports, customs and tax authorities’ strikes;

• changes in transportation market regulations;

• energy and water shortages and rationing;

• price increases of oil and other inputs;

• price instability;

• social and political instability;

• fiscal policies; and

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

Instability resulting from any changes made by the Brazilian government to policies or regulations that may affect these or other factors in the future may contribute to economic uncertainty in Brazil and intensify the volatility of Brazilian securities markets and securities issued abroad by Brazilian companies. The President of Brazil has the power to define the policies and actions of the Brazilian government in relation to the Brazilian economy and thereby affect the operations and financial performance of Brazilian companies. The Brazilian government may be subject to internal pressure to indent the current macroeconomic policies in order to achieve higher rates of economic growth. We cannot predict what policies will be adopted by the Brazilian government. Moreover, in the past, the Brazilian economy has been affected by the country’s political events, which have also affected the confidence of investors and the public in general, thereby adversely affecting the performance of the Brazilian economy. Furthermore, any indecisiveness by the Brazilian government in implementing changes to certain policies or regulations may contribute to economic uncertainty in Brazil and heightened volatility for the Brazilian securities markets and securities issued abroad by Brazilian companies.

These factors, as well as uncertainty as to whether the Brazilian government will apply changes to its policy or regulations that may affect any of the above-mentioned factors or other factors in the future, can lead to economic uncertainty and increase the volatility of the capital markets and the securities issued by Brazilian companies. Changes in such policies and regulations may have a negative impact on our operating results and financial position and the price of the shares.

The levels of economic activity, reflected in Brazilian GDP, can influence our distributed volumes. The growth rates in natural gas consumption may occur primarily by substituting other resources, notably fuel oil, gasoline and to a lesser extent other products derived from oil, depending on the prices of each kind of fuel.

We, our subsidiaries and jointly-controlled entities generally invoice our sales in reais, but a substantial portion of our, our subsidiaries’ and jointly-controlled entities’ net sales is from export sales that are billed in U.S. dollars. At the same time, the majority of our, our subsidiaries’ and jointly-controlled entities’ costs are denominated in reais. As a result, our operating margins are negatively affected when there is an appreciation of the real to the U.S. dollar. Additionally, we have indebtedness with fixed and floating rates, and we are thus exposed to the risk of fluctuations in interest rates. If there is an increase in interest rates, our financial results may be affected.

Ongoing political instability in Brazil may adversely affect the Brazilian economy and have a material adverse effect on us.

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, and have historically resulted in economic deceleration and heightened volatility in the trading market for securities issued by Brazilian companies.

Recently, the deteriorating political environment in Brazil has contributed to economic instability. 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 “Lava Jato,” have negatively impacted the political environment.

In August 2016, the Brazilian Senate approved the removal of Dilma Rousseff, Brazil’s then-President from office, after completion of the legal and administrative process for impeachment, for infringing budgetary laws. Michel Temer, the former Vice-President, who had previously assumed the interim presidency of Brazil since Ms. Rousseff’s suspension in May, was sworn in by the Brazilian Senate to serve out the remainder of the presidential term until the next general election in October 2018. There was an ongoing proceeding before the Brazilian Higher Electoral Court (Tribunal Superior Eleitoral) alleging that the electoral alliance between Ms. Rousseff and Mr. Temer in the 2014 general election had violated campaign finance laws. On June 9, 2017, the Brazilian Higher Electoral Court absolved Mr. Temer of wrongdoing; however, he is still being subjected to heightened scrutiny due to the ongoing Lava Jato investigations. Subsequently in June 2017, additional corruption charges were levied against Mr. Temer. In August 2017, the Brazilian Chamber of Deputies narrowly voted against having these charges heard by the Brazilian Supreme Court, which is the only tribunal in Brazil tasked with adjudicating allegations against a sitting President. Despite these findings, Mr. Temer is still subject to investigations being conducted by the Brazilian Federal Police and the Office of the Brazilian Federal Prosecutor and may be indicted in connection with certain allegations of corruption and ultimately subject to impeachment proceedings. We cannot predict which policies Mr. Temer may adopt or change during his mandate or the effect that any such policies might have on our business and on the Brazilian economy. Any such new policies or changes to current policies may have a material adverse effect on us.

Further, presidential elections are to be held in Brazil in the second half of 2018. We cannot predict the outcome of those elections, including whether any successor to Mr. Temer will adopt policies or changes to current policies which may have a material adverse effect on us. Furthermore, the political uncertainty resulting from the presidential elections may have an adverse effect on our business, results of operations and financial condition.

Any deterioration in Brazil’s rate of economic growth, changes in interest rates, the unemployment rate or price levels generally resulting in whole or in part from political developments in Brazil may adversely affecting demand for our products. Continuing political instability in Brazil could also have a material adverse effect on us.

The ongoing economic and political crisis in Brazil may have a material adverse effect on our business, operations and financial condition.

The recent economic instability in Brazil caused by the rise of inflation, a slowdown in GDP growth and uncertainty as to whether the Brazilian government will enact the necessary economic reforms to improve Brazil’s deteriorating fiscal accounts and economy have led to a decline in market confidence in the Brazilian economy and a government crisis.

Moreover, the Brazilian government may be subject to internal pressure to change its current macroeconomic policies in order to achieve higher rates of economic growth. We cannot predict what policies will be adopted by the Brazilian government. As has happened in the past, the Brazilian economy has been affected by the country’s political events, which have also affected the confidence of investors and the public in general, thereby adversely affecting the performance of the Brazilian economy. Furthermore, any indecisiveness by the Brazilian government in implementing changes to certain policies or regulations may contribute to economic uncertainty in Brazil and heightened volatility for the Brazilian securities markets and securities issued abroad by Brazilian companies.

42

We are not able to fully estimate the impact of global and Brazilian political and macroeconomic developments on our business. In addition, due to the current political instability, there exists substantial uncertainty regarding future economic policies and we cannot predict what policies will be adopted by the Brazilian government and whether these policies will negatively affect the economy or our business or financial performance. 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 our securities. Any continued economic instability and political uncertainty may have a material adverse effect on our business.

Inflation and government measures to curb inflation may adversely affect the Brazilian economy, the Brazilian securities market, our business and operations and the market prices of our shares.

Brazil has experienced extremely high rates of inflation in the past and has therefore implemented monetary policies that have resulted in one of the highest interest rates in the world. According to the IGP-M, a general price inflation index, the inflation rates in Brazil were, 5.5% in 2013, 3.7% in 2014, 10.5% in 2015, 7.2% in 2016 and a decrease of 0.5% in 2017. In addition, according to the National Extended Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo), published by the IBGE, the Brazilian price inflation rates were 5.6% in 2013, 6.2% in 2014, 11.3% in 2015, 6.6% in 2016 and 3% in 2017. Despite the Brazilian Central Bank’s repeated increases of interest rates during the period from 2013 to 2015, the IPCA has continued to increase, reaching 10.7% in 2015 (the highest level recorded since 2003), and reaching 3% for the twelve-month period ending December 31, 2017.

The Brazilian government’s measures to control inflation have often included maintaining a tight monetary policy with high interest rates, thereby restricting availability of credit and reducing economic growth. Inflation, actions to combat inflation and public speculation about possible additional actions have also contributed materially to economic uncertainty in Brazil and to heightened volatility in the Brazilian securities markets. The Brazilian government’s measures to fight inflation, principally through the Brazilian Central Bank, have had and may in the future have significant effects on the Brazilian economy and our business.

Brazil may experience high levels of inflation in future periods. Periods of higher inflation may slow the rate of growth of the Brazilian economy, which could lead to reduced demand for our products in Brazil and decreased net sales. Inflation is also likely to increase some of our costs and expenses, which we may not be able to pass on to our customers and, as a result, may reduce our profit margins and net income. In addition, high inflation generally leads to higher domestic interest rates, and, as a result, the costs of servicing any floating-rate real-denominated debt may increase, resulting in lower net income. Inflation and its effect on domestic interest rates can, in addition, lead to reduced liquidity in the domestic capital and lending markets, which could affect our ability to refinance our indebtedness in those markets. Future Brazilian governmental actions, including interest rate decreases, intervention in the foreign exchange market and actions to adjust or fix the value of the real, may trigger increases in inflation and adversely affect the performance of the Brazilian economy as a whole. Any of the aforementioned developments may adversely affect the Brazilian economy as a whole, as well as on our financial conditions, operations and profits. Any decline in our net sales or net income and any deterioration in our financial performance would also likely lead to a decline in the market price of our shares.

High interest rates may adversely affect our operations and financial condition.

The Brazilian government’s measures to control inflation have frequently included maintaining a restrictive monetary policy with high interest rates, thereby limiting the availability of credit and reducing economic growth. As a consequence, official interest rates in Brazil at the end of 2017, 2016 and 2015 were 7%, 13.75% and 14.25% per year, respectively, as established by the monetary policy committee of the Brazilian Central Bank (COPOM). Brazilian interest rates have remained high and any increase of such interest rates may negatively affect our profits and results of operations, thereby increasing the costs of financing our operations.

High interest rates may impact our cost of obtaining loans and also the cost of indebtedness, resulting in an increase in our financial expenses. This increase may adversely affect our ability to pay our financial obligations, as it reduces our cash availability. Mismatches between contracted indexes for assets versus liabilities and/or high volatilities in interest rates may result in financial losses for us.

43

As of December 31, 2017, our consolidated gross debt was either fixed or linked to interest rates based on the CDI (Interbank Deposit Certificate) rate, the TJLP (Long-Term Interest Rate), the IPCA and the SELIC rate. We enter into certain financial instruments to mitigate our exposure to interest rate fluctuations.

Significant volatility in the value of the real in relation to the U.S. dollar could harm our ability to meet our U.S. dollar-denominated liabilities.

Due to inflationary pressures and adjustments to economic policy, the Brazilian currency has historically experienced volatility against the U.S. dollar and other foreign currencies. In the past, the Brazilian government has implemented various economic plans and exchange rate policies, including sudden devaluations and periodic mini-devaluations, during which the frequency of adjustments has ranged from daily to monthly, fluctuation band exchange rate systems, exchange controls and dual exchange rate markets.

There have been significant fluctuations in the exchange rate between the Brazilian currency and the U.S. dollar and other currencies. For example, the Brazilian real depreciated 19.7% and 53.2% against the U.S. dollar in 2001 and 2002, respectively and appreciated 18.0%, 8.0%, 12.3%, 8.5% and 17.0% against the U.S. dollar in 2003, 2004, 2005, 2006 and 2007, respectively. In 2008, the real depreciated again approximately 31.9% against the U.S. dollar. In 2009, the real appreciated 25.3% against the U.S. dollar, while in December 31, 2010 the real to U.S. dollar exchange rate was R$1.6662, according to the Brazilian Central Bank. In 2011, the real depreciated by 13.6% against the U.S. dollar, from R$1.6510 in the beginning of the period to R$1.8758 by the end of the period, and in 2012 the real went from R$1.8683 in the beginning of the year to R$2.0435 by the end of the period, amounting to a 9.4% depreciation against the U.S. dollar. In 2013, the real went from R$2.0415 in the beginning of the year to R$2.3426 by the end of the period. In 2014, the real went from R$2.3975 in the beginning of the year to R$2.6562 by the end of the period, corresponding to a 10.8% depreciation against the U.S. dollar.

However, during 2015, due to the poor economic conditions in Brazil, including as a result of political instability, the real has devalued at a rate that is much higher than in previous years. On September 24, 2015, the real fell to the lowest level since the introduction of the currency, at R$4.1949 per U.S.$1.00. In 2015, the real depreciated 45%, reaching R$3.9048 per U.S.$1.00 on December 31, 2015. Conversely, in 2016, the real went from R$4.0387 per U.S.$1.00 at the beginning of the year to R$3.2591 per U.S.$1.00 on December 31, 2016, corresponding to a 19.3% appreciation against the U.S. dollar. In 2017, the real went from R$3.2729 per U.S.$1.00 at the beginning of the year to R$3.3080 per U.S.$1.00 on December 31, 2017, corresponding to a 1% depreciation against the U.S. dollar. There can be no assurance that the real will not depreciate or appreciate further against the U.S. dollar.

Because Cosan, its subsidiaries and jointly-controlled entities generally invoices its sales in reais, devaluation of the real against foreign currencies may generate losses from our foreign currency-denominated liabilities as well as an increase in our funding costs with a negative impact on our ability to finance our operations through access to the international capital markets and on the market value of the shares. A strengthening of the real in relation to the U.S. dollar generally has the opposite effect. Further devaluations of the Brazilian currency may occur and impact our business in the future. These foreign exchange and monetary gains or losses can be substantial, which can significantly impact our earnings from one period to the next. In addition, depreciation of the real relative to the U.S. dollar could (1) result in additional inflationary pressures in Brazil by generally increasing the price of imported products and services and requiring recessionary government policies to curb demand and (2) weaken investor confidence in Brazil and reduce the market price of the shares. On the other hand, further appreciation of the real against the U.S. dollar may lead to a deterioration of the country’s current account and the balance of payments and may dampen export-driven growth.

In addition, we are active in the credit market, obtaining funds denominated in national and foreign currencies to finance our investments and working capital. Our foreign currency exposure related to indebtedness as of December 31, 2017 was R$10,376.4 million compared to R$5,864.3 million at December 31, 2016. We manage a portion of our exchange rate risk through foreign currency derivative instruments, but our foregoing currency debt obligations are not completely hedged. As a result, the possible depreciation of the real against the U.S. dollar could increase the cost of our obligations in foreign currency, and therefore significantly affect our liquidity and our cash flows in the short term. The depreciation of the real may limit our access to international capital markets and may favor state intervention in the economy, including the imposition of potentially recessionary policies.

Infrastructure and workforce deficiency in Brazil may impact economic growth and have a material adverse effect on us.

Our performance depends on the overall health and growth of the Brazilian economy. Brazilian GDP growth has fluctuated over the past few years, with growth of 2.7% in 2013 decreasing to 0.1% in 2014 and then to a contraction of 3.8% in 2015, a contraction of 3.6% in 2016 and an increase of 1% in 2017. Continued growth is limited by inadequate infrastructure, including potential energy shortages and deficient transportation, logistics and telecommunication sectors, the lack of a qualified labor force and the lack of private and public investments in these areas, which limit productivity as well as efficiency. Any of these factors could lead to labor market volatility and generally impact income, purchasing power and consumption levels, which could limit growth or result in contraction and ultimately have a material adverse effect on our business.

Furthermore, deficiencies in the road, rail or waterway network of the areas in which we operate, such as unpaved or maintenance-free roads lack of railroads, especially in regions farthest from the ports, result in high logistics costs and, consequently, reduce the profitability of our sugarcane operations. Likewise, failure or malpractice in transportation handling, whether on trains, trucks or vessels, may lead to loss of production, waste of quantities or damage to sugarcane. Constant climate change, such as excessive rainfall, has led to a worsening of the road’s conservation status, which may lead to an increase in over-production losses. The aforementioned infrastructure deficiencies may make it more difficult for us to conduct our business in the areas in which we operate and thereby adversely affect us.

Developments and the perception of risk in other countries may adversely affect the Brazilian economy and market price of Brazilian issuers’ securities.

The market value of securities of Brazilian issuers is affected by economic and market conditions in other countries, including the United States, European countries, as well as in other Latin American and emerging market countries. Although economic conditions in Europe and the United States may differ significantly from economic conditions in Brazil, investors’ reactions to developments in these other countries may have an adverse effect on the market value of securities of Brazilian issuers. Additionally, crises in other emerging market countries may diminish investor interest in securities of Brazilian issuers, including our securities, as well as adversely affect the availability of credit to Brazilian companies in the foreign market, with the significant outflow of resources from the country and decrease in the amount of foreign currency invested in the country. In addition, negative events in the Brazilian financial and capital markets, any news or evidence of corruption in publicly traded companies and other issuers of securities, and the lack of rigorous application of investor protection rules or lack of transparency of information or eventual crisis situations in the Brazilian economy and in other economies may influence the Brazilian capital markets and negatively impact the securities issued in Brazil. This could adversely affect the market price of our securities, restrict our access to capital markets and compromise our ability to finance our operations in the future on favorable terms, or at all.

In recent years, there was an increase in volatility in all Brazilian markets due to, among other factors, uncertainties about how monetary policy adjustments in the United States would affect the international financial markets, the increasing risk aversion to emerging market countries and the uncertainties regarding Brazilian macroeconomic and political conditions. These uncertainties adversely affected us and the market value of our securities.

In addition, we continue to be exposed to disruptions and volatility in the global financial markets because of their effects on the financial and economic environment, particularly in Brazil, such as a slowdown in the economy, an increase in the unemployment rate, a decrease in the purchasing power of consumers and the lack of credit availability.

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 our business, results of operations and financial condition.

45

Events in other countries may have a negative impact on the Brazilian economy.

Global economic conditions may affect the Brazilian economy as well as the demand for our products (including ethanol). For example, a global recession may lead to a reduction in global demand for our products, either through lower consumption or via measures to protect local production. In both cases the consequence would be to reduce prices for our products in the foreign market, affecting our financial performance. In addition, as a portion of our net operating revenues is generated from export activities and normally billed in U.S. dollars and, at the same time, most of our costs are denominated in reais, our operating margins may be adversely affected when the real appreciates against the U.S. dollar. In addition, we have indebtedness at pre-and post-fixed rates and, therefore, we are exposed to the risk of interest rate variations. If there is an increase in interest rates, our financial results may be affected.

On January 20, 2017, Donald Trump became the President of the United States. The results for the 2016 United States presidential and congressional elections have generated volatility in the global capital markets. Such volatility and uncertainty, as well as changes in administrative and governmental policies of the new administration may have a material adverse effect on global economic conditions and the stability of global financial markets. Asset valuations, currency exchange rates and credit ratings may be especially subject to increased market volatility. We have no control over and cannot predict the effects arising from the new United States administration or its policies. Any disruption to global economic conditions and the stability of global financial markets could have a material adverse effect on us and the market value of our securities.

On June 23, 2016, the United Kingdom held a non-binding referendum on its membership in the European Union, in which a majority voted for the United Kingdom to leave the European Union. Immediately following the result, the United Kingdom and global stock and foreign exchange markets commenced a period of significant volatility, including a steep devaluation of the pound sterling, in addition to which there is now continuing uncertainty relating to the process, timing and negotiation of the United Kingdom’s exit from, and future relationship with, the European Union. On March 29, 2017, the United Kingdom’s Prime Minister gave notice under Article 50(2) of the Treaty on European Union of the United Kingdom’s intention to withdraw from the European Union. The delivery of the Article 50(2) notice has triggered a two-year period of negotiation which will determine the terms on which the United Kingdom will exit the European Union and the new terms of the United Kingdom’s relationship with the European Union. Unless extended, the United Kingdom’s membership of the European Union will cease after this two-year period. These negotiations with the European Union, which formally commenced on June 19, 2017, are expected to run in parallel to standalone bilateral negotiations with the numerous individual countries and multilateral counterparties with which the United Kingdom currently has trading arrangements by virtue of its membership of the European Union. The timing of, and process for, such negotiations and the resulting terms of the United Kingdom’s future economic, trading and legal relationships are uncertain. Uncertainty regarding the terms of the United Kingdom’s withdrawal from the European Union, and its eventual effects once implemented, could adversely affect European or global economic or market conditions and investor confidence. This could, in turn, adversely affect our business and/or the market value of our securities.

A reduction in the volume of foreign investments in Brazil may have a negative impact on us.

Any reduction in the volume of foreign investments in Brazil may have an impact on the balance of payments, which may force the Brazilian government to have a greater need to raise funds, both in the domestic and in the international markets, at higher interest rates. Likewise, any significant increase in Brazilian inflation rates and the current slowdowns of the European and American economies may have a negative impact on the Brazilian economy and affect interest rate levels, raising expenses on loans already obtained and costs of new funding from resources by Brazilian companies, including us.

Future governmental policy and regulations may adversely affect our operations and profitability.

Our activities may be materially affected by policies and regulations from Brazilian and foreign federal, state and municipal government. Governmental policies affecting economic activity such as tariffs, taxes, subsidies and restrictions on the import and export of agricultural goods and commodities, which represent a substantial part of the cargo we transport, may influence the profitability of the industry as well as the volume and type of imports and exports.

46

Future Brazilian and foreign governmental policies may adversely affect the supply, demand and prices of our products and services or otherwise restrict our capacity to operate in our current or prospective markets, potentially affecting our financial performance.

Changes in taxes and other assessments may adversely affect us.

The legislatures and tax authorities in the tax jurisdictions in which we operate regularly enact reforms to the tax and other assessment regimes to which we and our customers are subject. Such reforms include changes in tax rates and, occasionally, enactment of temporary taxes, the proceeds of which are earmarked for designated governmental purposes. In addition, the interpretation of tax laws by courts and taxation authorities is constantly evolving. In Brazil, the tax system is highly complex and the interpretation of the tax laws and regulations is commonly controversial. The effects of these changes and any other changes that result from enactment of additional tax reforms or changes to the manner in which current tax laws are applied cannot be quantified and there can be no assurance that any such reforms or changes would not have an adverse effect upon our business.

The Brazilian government regularly implements changes to tax regimes that may increase the tax burden on us, our subsidiaries and jointly-controlled entities and their respective customers. These changes include modifications in the rate of assessments and the enactment of new or temporary taxes, the proceeds of which are earmarked for designated governmental purposes. Future changes in tax policy laws may adversely affect our financial and operating results.

Ongoing investigations relating to corruption and diversion of public funds that are being conducted by the Brazilian federal police as well as other Brazilian and non-Brazilian regulators and law enforcement officials may adversely affect the growth of the Brazilian economy and could have a material adverse effect on us.

Certain Brazilian companies active in the oil and gas, energy, construction and infrastructure sectors are facing investigations by the CVM, the SEC, the U.S. Department of Justice, the Brazilian Federal Police and the Brazilian Federal Prosecutor’s Office, the Comptroller General of Brazil and other relevant governmental authorities, in connection with corruption allegations (the so called “Lava Jato” investigations). The Brazilian federal police is also investigating allegations of improper payments made by Brazilian companies to officials of the Board of Tax Appeals (Conselho Administrativo de Recursos Fiscais), or “CARF,” a tax appeals tribunal (the so-called “Operação Zelotes”). It is alleged that the purpose of such improper payments was to induce those officials to reduce or waive certain tax-related penalties imposed by the Brazilian federal revenue authority, which were under appeal in the CARF. Such investigations involve several companies and individuals, including representatives of various companies, politicians and third parties. Certain of these individuals are being investigated by the Brazilian Federal Police and others were formally charged and are facing criminal proceedings and/or have already been convicted by the Brazilian Federal Courts.

Depending on the duration and outcome of such investigations, the companies involved may face a reduction in their revenues, downgrades from rating agencies or funding restrictions, among other negative effects. Given the significance of the companies cited in these investigations in the Brazilian economy, the investigations and their fallout have had an adverse effect on Brazil’s economic growth prospects in the near, short to medium term. Furthermore, the negative effects on such companies and others may also impact the level of investments in infrastructure in Brazil, which may lead to lower economic growth or contraction in the near to medium term (according to data from the IBGE, the Brazilian economy’s gross domestic product, or “GDP,” contracted by 3.5% in 2015 and 3.5% in 2016 but increased by 1.0% in 2017). In addition, although we have reduced our exposure to companies involved in the “Lava Jato” and other government investigations, we cannot assure you that new investigations will not be launched or that additional persons will not become subject to investigation.

As a result of the allegations under the “Lava Jato” investigations and the economic downturn, Brazil was downgraded to non-investment grade status by Standard & Poor’s, or “S&P,” in September 2015, by Fitch Ratings, or “Fitch,” in December 2015, by Moody’s Investors Service in February 2016 and downgraded again by Fitch in May 2016. In addition, Brazil was further downgraded by S&P to BB- with a stable outlook in January 2018 as a result of the failure of the current Brazilian government to approve certain pension reforms. Various major Brazilian companies were also downgraded. Such downgrades have further worsened the conditions of the Brazilian economy and the condition of Brazilian companies, especially those relying on foreign investments.

47

Such investigations have recently extended to persons in high positions in the executive and legislative branches of the Brazilian government, which has caused considerable political instability. It is difficult to predict the effects of such political instability. Persistent economic hardship in Brazil resulting from, among other factors, such investigations, the developments arising therefrom and a scenario of high political instability may have a material adverse effect on us.

Persistently poor macroeconomic conditions in Brazil resulting from, among other things, the “Lava Jato” investigations and their consequences could have a material adverse effect on us.

If we do not successfully comply with laws and regulations designed to prevent governmental corruption in countries in which we sell our products, we could become subject to fines, penalties or other regulatory sanctions and our sales and profitability could suffer.

Our anti-corruption policies and procedures designed to prevent governmental corruption violations may not prevent our management, employees or third parties acting on our behalf in the countries in which we operate from taking actions that violate applicable laws and regulations on improper payments to government officials for the purpose of obtaining or keeping business or business advantages. Laws prohibiting such behaviors include (but are not limited to) laws relating to the OECD’s 1997 Convention on Combating Bribery of Foreign Public Officials in International Business Transactions, such as the U.S. Foreign Corrupt Practices Act, and Brazilian Law No. 12,846/13, or the Anticorruption Act, which has been in effect since January 29, 2014. Any breach thereof may have a material adverse effect on our business, including the acceleration of loans and financing.

The Anticorruption Act imposes strict liability on companies for acts of corruption, fraud or manipulation of public tenders and government contracts; and interference with investigations or inspections by governmental authorities. Companies found liable under the Anticorruption Act face fines of up to 20% of their gross revenue in the immediately preceding year or, if such annual gross revenue cannot be estimated, such fines may range from R$6 thousand to R$60 million. Among other sanctions, the Anticorruption Act also provides for the seizure of assets or benefits obtained illegally, the suspension or partial prohibition of operations, the dissolution of the entity and/or the prohibition to receive incentives, subsidies, donations or financing from the government or from government-controlled entities for up to five years. In assessing penalties under the Anticorruption Act, Brazilian authorities may consider the adoption of an effective compliance program. Other relevant laws applicable to corruption-related violations, such as Law No. 8.492/92, or the Administrative Improbity Law, also provide for penalties that include the prohibition to enter into government contracts for up to ten years.

Consequently, if we, our management, employees or third parties acting on our behalf in the countries in which we sell our products become involved in any anti-corruption or criminal investigations or proceedings in connection to our business in Brazil or in any other jurisdiction, our business could be materially adversely affected.

In March 2012, Cosan S.A. entered into an agreement to acquire Comma, a wholly-owned subsidiary of Esso Petroleum Company Limited to enter into the European lubricants and specialties market. Comma is located in England and manufactures and supplies lubricants, seasonal and car care products to the United Kingdom and other export markets in Europe and Asia, primarily under the Comma brand. In addition, agreements will be in place to allow Comma to continue to distribute select Mobil-branded lubricants through certain United Kingdom channels and to continue to manufacture and supply ExxonMobil companies with a range of seasonal and ancillary automotive products. The transaction was concluded on July 1, 2012.

On October 24, 2012, Cosan S.A. and its subsidiary Handson Participações S.A., or “Handson” entered into a purchase and sale agreement with Camil Alimentos S.A., or “Camil,” for the sale of our subsidiary Docelar Alimentos e Bebidas S.A., or “Docelar,” to Camil, for R$463.8 million. As consideration for this amount, at the closing of the transaction Camil assumed indebtedness of R$170.0 million and paid cash of R$88.7 million. The remaining R$205.0 million was settled in four payments. The sale was approved by the Brazilian antitrust authority (Superintendência-Geral do Conselho Administrativo de Defesa Econômica or “CADE”) on July 19, 2012. The outstanding payments are secured by a trust receipt on our behalf of 28,246,685 shares of Camil, corresponding to 25% of its capital stock. In addition, pursuant to the agreement, we and our affiliates cannot compete with Camil or Docelar for five years from the date of the agreement.

Also in May 2012, Cosan S.A., through its subsidiary Provence Participações S.A., or “Provence,” entered into a Stock Purchase Agreement to acquire 60.1% for R$3.4 billion of Comgás from BG Group. Our acquisition of a 60.1% stake of Comgás was concluded on November 5, 2012, with full approval from, and no restrictions were imposed by CADE or ARSESP (the relevant sectoral regulator). As a result of this acquisition, we entered into a shareholders’ agreement with the other principal shareholders of Comgás, Integral Investments B.V. and Shell Brazil Holding BV, subsidiaries of Shell Gas BV of the Shell Group. Shell Brazil Holding BV, which has a direct and indirect interest in Comgás, corresponding to 18.2% of its share capital, was granted an option to convert its current stake of 21,805,645 Comgás common shares into 30,917,231 of Cosan S.A. shares. The exercise of this option may occur during a period of approximately 30 days at the third, fourth or fifth anniversary from the closing date.

On February 24, 2014, Cosan S.A., through its subsidiary Rumo submitted to ALL a binding proposal for the merger of ALL by Rumo. The proposal entailed the merger of all the shares issued by ALL into Rumo, with the existing shareholders of Rumo and ALL receiving 36.5% and 63.5%, respectively, of the capital stock of the combined company. The merger was subject to certain conditions precedent, notably the following: (1) Rumo had to become registered as a Brazilian publicly held company and simultaneously join the “Novo Mercado” segment of B3; (2) regulatory approvals from CADE and the ANTT being obtained; and (3) all corporate and third-party approvals required by applicable laws and the by-laws of the companies being obtained.

At an extraordinary general meeting held on October 1, 2014, Cosan S.A.’s shareholders approved a spin-off of the logistics business of Cosan S.A. and the merger of the spun-off portion into Cosan Logística (the “Partial Spin-off”). The Partial Spin-off sought to segregate Cosan S.A.’s logistics activities, focused on Rumo, in order to allow each of our business segments to be more sector-focused, and to establish a suitable capital structures for each business segment. It also seeks to provide the market with greater transparency on each business segment’s performance, which will give shareholders and investors an improved ability to analyze each individual business’ performance. Cosan Limited controls both Cosan S.A. and Cosan Logística, with a 62.51% and 62.51% interest in each of them, respectively. At September 30, 2014 the portion spun-off to Cosan Logística had a book value of R$1,059.5 million. Due to the Partial Spin-off, all of the shares issued by Cosan Logística previously held by Cosan were canceled and subsequently 405,856,814 new Cosan Logística shares were issued to the shareholders of Cosan (including Cosan Limited) at an exchange ratio of 1:1. Cosan’s shares were traded ex-rights to receive Cosan Logística’s shares as from October 6, 2014. Cosan Logística’s shares are currently traded on the B3 under the ticker “RLOG3,” with trading having started on October 6, 2014. As a result, shareholders had been provided with the same political and economic privileges in Cosan Logística as those conferred on them by the shares of the company they previously held. Furthermore, the Partial Spin-off did not result in any change in the characteristics of Cosan’s shares or the advantages conferred by them. Due to the Partial Spin-off and consequent transfer of the spun-off portion to Cosan Logística, the share capital of Cosan S.A. was reduced by R$1,059,591, corresponding to the book value of the spun-off portion, without any cancellation of Cosan S.A.’s shares. As such, Cosan S.A.’s share capital reduced from the current R$4,691,822 to R$3,632,231, and it remains divided into 407,214,353 registered common, nominative and without par value shares.

On April 1, 2015, following the completion of the applicable conditions precedent, the merger between Rumo and ALL was effected with an adjusted exchange ratio (adjusted by the dividends distributed per each company during the period) that gave Rumo’s shareholders 34.3% and ALL’s shareholders 65.7% of the capital stock of the combined company. As a result, ALL’s shares (B3 ticker: ALLL3) were delisted from B3 as of March 31, 2015. As of April 1, 2015, Rumo’s public shares listed on the B3 (under the ticker “RUMO3”) fully reflected the effects of the merger.

On April 13, 2016, Rumo completed a capital increase in an amount of R$2.6 billion through a public offering of its common shares to investors in Brazil and abroad. Rumo used the net proceeds from the offering to strengthen its working capital and make investments.

In June 2016, Cosan Luxembourg S.A., or “Cosan Luxembourg,” a subsidiary of Cosan S.A., commenced a cash tender offer, or the tender offer, for any and all of (i) the R$850.0 million 9.50% Senior Notes due 2018, or the “2018 Notes,” and (ii) the U.S.$500.0 million 5.00% Senior Notes due 2023, or the “2023 Notes.”

In conjunction with the tender offer, Cosan Luxembourg also solicited consents of the holders of the 2018 Notes and the 2023 Notes to eliminate substantially all of the restrictive covenants and certain events of defaults and related provisions contained in the applicable indenture governing such series of notes. As of July 1, 2016, the expiration date for the consent solicitation, (i) R$686,538,000 in aggregate principal amount of the 2018 Notes, or approximately 80.8% of the outstanding 2018 Notes, and (ii) U.S.$378,687,000 in aggregate principal amount of the 2023 Notes, or approximately 75.7% of the outstanding 2023 Notes, had been validly tendered pursuant to the tender offer. The requisite consents were obtained and a supplemental indenture eliminating the restrictive covenants and certain events of default was executed.

Concurrently with the tender offer, on June 9, 2016, Cosan Luxembourg sold an aggregate principal amount of U.S.$500 million in 7.000% senior notes due 2027. An additional U.S.$150 million in aggregate principal amount of 7.000% senior notes due 2027 were issued on July 18, 2016. The senior notes due 2027 are unconditionally and irrevocably guaranteed by Cosan S.A. The net proceeds from the offering of the senior notes due 2027 were used to pay the tender price of any 2018 Notes and/or 2023 Notes that were tendered in connection with the tender offer. Any remaining funds were used for general corporate purposes.

On September 30, 2016, Cosan S.A. entered into a Share Purchase Agreement with Mansilla Participações Ltda. (a vehicle of TIAA Teachers Insurance and Annuity Association of America), another shareholder in Radar Propriedades Agrícolas S.A. and Radar II Propriedades Agrícolas S.A., or “Radar and Radar II,” through which Cosan S.A. sold part of its shares in Radar and Radar II for an amount of R$1,053.8 million. The consideration was received on November 4, 2016. As a result of this transaction, Cosan S.A. reduced its equity interest in Radar and Radar II from 37.7% to 3%. Cosan S.A. retains significant influence over Radar and Radar II through a shareholders’ agreement as described in “Item 7. Major Shareholders and Related Party Transactions.” The criteria used to measure the remaining stake of the investment was the equity method, in accordance with IAS 28, although it is not consolidated due to the inhibition of Cosan’s decision-making power defined on the shareholders agreement. The comparative consolidated statement of profit or loss and statements of cash flows have been restated to show the discontinued operation separately from continuing operations.

On October 8, 2016, ALL – América Latina Logística S.A. changed its corporate name to Rumo S.A. Subsequently, on December 31, 2016, Rumo Logística was merged into its wholly-owned subsidiary Rumo S.A., as a result of which Rumo S.A. is the successor entity to Rumo Logística.

In November 2016, Cosan S.A. and Shell executed amendments to certain agreements between them to remove the fixed date call options over Raízen Energia and Raízen Combustíveis shares exercisable in 2021 and 2026, and replace them with certain call and put options exercisable by Shell or Cosan S.A. upon the occurrence of certain events including, among others: (i) fundamental breaches of the obligations provided for in the agreements governing the Joint Venture; (ii) breach of anticorruption laws, (iii) insolvency or bankruptcy of a party, (iv) change of control, and (v) in the event of the death or disability of Cosan S.A.’s current Chairman, Mr. Rubens Ometto Silveira Mello. Moreover, Cosan S.A. and Shell agreed to renew the existing lock-up period for five years from the date of the execution of the amendment, following which the parties may sell their shares in each of Raízen Energia and Raízen Combustíveis subject to compliance with certain preemption rights in each other’s favor.

Currently, Raízen Combustíveis and its competitors purchase all or nearly all oil-derivative fuels from Petrobras under a formal supply contract that establishes the volume and the terms for supply. The contract is renewed periodically and the volume contracted for is based on the volume purchased in the previous year. There have been no significant interruptions in the supply of fuels from Petrobras to the distributors.

Ethanol is sourced from various third-party suppliers and from Raízen Energia as well. The prices of ethanol supplied are generally determined by the ESALQ index. The prices of oil-derivative fuels supplied to us by Petrobras generally vary according to international oil prices.

All of our fuel distribution operations are in the domestic Brazilian market. Our operations are not subject to significant seasonality; however, the price of hydrous ethanol at the pump is typically more volatile than the prices of gasoline or diesel, as a result of the seasonality of the sugarcane harvest and the limited storage facilities for ethanol in Brazil. This in turn impacts the proportion of our revenue mix that is derived from either gasoline or ethanol throughout the year, as consumers who own flex fuel vehicles switch between the two fuels according to the relative price of each.

As hydrous ethanol is less energy intense than gasoline, consumers will usually switch to ethanol if the price is significantly lower than gasoline. When hydrous ethanol is retailed at 70% of the price of gasoline, the two fuels are considered to be at price parity with each other. At a level below 70%, the demand for ethanol will significantly increase at the expense of gasoline.

Raízen Combustíveis supplies aviation fuel at 68 airports across Brazil, including at the major hubs of Congonhas and Guarulhos airports in São Paulo, and Brasília airport in the Federal District, to Brazilian and foreign airlines.

In addition, as of December 31, 2017, we had 950 convenience stores (compared to 961, 944 and 863 as of December 31, 2016, 2015 and 2014, respectively) throughout Brazil.

Regulation

The National Agency of Petroleum, Natural Gas and Biofuels, or “ANP,” is a federal agency responsible for the control, supervision and implementation of the government’s oil, gas and biofuel regulations. The ANP regulates all aspects of the production, distribution and sale of oil, natural gas, and biofuels products in Brazil. With respect to regulation relating to gasoline and biofuels, the ANP determines the product quality standards and minimum storage capacities required to be maintained by distributors and is also responsible for establishing the limits of oil-based fuel volume purchased by distributors based on their storage capacity.

Fuel distributors are subject to Brazilian federal, state and municipal laws and regulations relating to environmental protection, safety and occupational health and safety, licensing by fire departments, environment and transport authorities. The National Environmental Council (Conselho Nacional do Meio Ambiente), or “CONAMA,” is the main government body responsible for issuing environmental standards and regulations at the federal level. Environmental state agencies and municipal departments are also responsible for establishing and supervising complementary laws and regulations within their areas of operation.

Fuel distributors must obtain authorizations and/or licenses from federal, state and/or municipal environmental agencies and fire departments to implement and operate their facilities. They are required to develop programs to control air, soil and water pollution, including management of hazardous waste.

Raízen Energia (Sugar, Ethanol and Cogeneration)

Overview

Raízen Energia is our upstream Joint Venture company. Raízen Energia’s core business is the production and sale of a variety of products derived from sugarcane, including VHP sugar, anhydrous and hydrous ethanol, as well as activities related to energy cogeneration from sugarcane bagasse and ethanol trading. Raízen Energia operates 26 sugar, ethanol and energy cogeneration mills, with a current crushing capacity of 73 million tons of sugarcane per year.

Our production is based on sugarcane, the most competitive and viable feedstock for sugar and ethanol because of its low production cost and high energy efficiency ratio relative to other energy sources, such as corn and sugar beet. Sugarcane is our principal raw material. It is a tropical grass that grows best in locations with stable warm temperatures and high humidity, although cold and dry winters are an important factor for the sucrose concentration of sugarcane. The climatic conditions of the central-south region of Brazil are ideal for growing sugarcane.

Raízen Energia’s sugarcane production is sourced from leased lands, as well as from third-party suppliers. The following table compares the amount of sugarcane grown on leased land with the amount purchased from third parties during the periods set out below.

	As of and for Fiscal Year Ended December 31
	2017		%		2016		%		2015		%
	(millions of tons, except percentages)
Own sugarcane harvested from leased land		29.1		47.9		31.3		50.4		28.9		48.3
Sugarcane purchased from third parties		31.6		52.1		30.9		49.6		31.0		51.7
Total		60.7		100		62.2		100		59.9		100

In accordance with the land lease contracts, we pay the lessors a certain fixed number of tons of sugarcane per hectare as consideration for the use of the land, and a certain fixed productivity per ton of sugarcane in terms of TSR. The overall volume of TSR is obtained by multiplying the number of hectares leased by the committed tons of sugarcane per hectare by the TSR per ton of sugarcane. The price that we pay for each kilogram of TSR is set by Consecana. The price that we pay to third-party sugarcane growers is based on the total amount of sugar content in the sugarcane, measured by the amount of sugar recovered and on the prices of ethanol and sugar sold by each mill.

Our mills have the capacity to crush 73 million tons of sugarcane per year and in the fiscal year ended December 31, 2017, we crushed 60.7 million tons of sugarcane, or 10.4% of Brazil’s central-south region total sugarcane production (which was 583.4 million tons as of December 31, 2017, according to UNICA). For further information on our sugarcane mills see “—D. Property, Plant and Equipment.” The mills that are equipped to produce both sugar and ethanol can typically adjust their proportion of output from anywhere between 57% sugar and 43% ethanol to 47.2% sugar and 52.8% ethanol. We track the current and future prices of each product relative to the other, as well as forecasts of global output volumes of each product, to decide on the production mix to be set across our mills in order to maximize our sales revenue. All of our mills are energy self-sufficient from burning sugarcane bagasse at very high temperatures in boilers, to heating water that is transformed into steam. Thirteen of our mills generate surplus electrical energy that we sell to the Brazilian energy grid.

We produce and sell a wide variety of standard sugars, including VHP sugar, crystal sugar and organic sugar, and refined sugars, including granulated refined white sugar, amorphous refined sugar, refined sucrose liquid sugar and refined inverted liquid sugar.

Standard sugars. VHP sugar, a raw sugar with approximately 99% sucrose content, is similar to the type of sugar traded in major commodities exchanges, including through the standard NY11 contract. The main difference between VHP sugar and the sugar that is typically traded in the major commodities exchanges is the sugar content of VHP sugar and the price premium that VHP sugar commands in comparison to most sugar traded in the commodities exchanges. We export VHP sugar in bulk, to be refined at its final destination. We also sell a small amount of VHP sugar to the Brazilian market. Crystal sugar is a non-refined sugar produced directly from sugarcane juice and sold to industrial companies in Brazil to be used as an ingredient for food products. We also sell a small amount of crystal sugar to the Brazilian retail market and to export markets. Organic sugar is a kind of raw sugar produced from organic sugarcane and is not submitted to any chemical treatments during its manufacturing process. We sell organic sugar in the international and Brazilian markets.

Refined sugars. We refine VHP sugar and crystal sugar into both granulated and amorphous (non-crystallized) sugar. We sell refined sugar in the Brazilian and export retail and industrial markets. Refined sugar is used as an ingredient in processed food products such as milk and chocolate powders, bakery products, powder refreshments, and pharmaceutical syrups.

Liquid sugars. We refine crystal sugar to produce sucrose liquid sugar and inverted liquid sugar, which has a higher percentage of glucose and fructose than sucrose liquid sugar. We sell both types of sugar for industrial use, mainly for the production of soft drinks.

We sell sugar to a wide range of customers in Brazil and in the international markets. Our customers in Brazil include Docelar, which was previously held by Cosan and sold to Camil. on October 24, 2012, and food manufacturers, for which we primarily sell refined and liquid sugar. We primarily sell raw sugar in the international markets through international commodities trading firms and Brazilian trading companies. In the fiscal year ended December 31, 2017 we exported 76.6%, by volume, of the sugar we sold. Rumo handles most of the transportation by rail and logistics of our sugar exports to their sugar loading terminal at the Port of Santos.

Prices for raw sugar are established in accordance with the NY11 futures contracts. Prices for refined sugar are established in accordance with the London# 5 futures contract, traded on the LIFFE. Prices for sugar we sell in Brazil are set in accordance with Brazilian market prices, using an index calculated by the ESALQ.

We produce and sell three different types of ethanol: hydrous ethanol and anhydrous ethanol for fuel and industrial ethanol. The primary type of ethanol consumed in Brazil is hydrous ethanol, which is used as an alternative to gasoline for flex fuel vehicles (as opposed to anhydrous ethanol which is used as an additive to gasoline). As a result, hydrous ethanol represented 58.8% of our ethanol production in the fiscal year ended December 31, 2017 and 63.5% of our ethanol production in the fiscal year ended December 31, 2016. Our sales are mainly to fuel distributors in Brazil, of which the three largest are Petrobras Distribuidora S.A. (BR Distribuidora), Raízen Combustíveis S.A. (Shell) and Cia. Brasileira de Petróleo Ipiranga (Ipiranga). We also sell industrial alcohol, which is used in the chemical and pharmaceutical sectors. In the fiscal year ended December 31, 2017, we exported 29.9%, by volume, of the ethanol we sold. Our main export customers are trading companies which distribute our products mainly to the United States, Japan and Europe. Our exports are conducted through TEAS, an ethanol loading terminal at the Port of Santos.

56

Ethanol Production Process

We produce ethanol through a chemical process called yeasting, which is a process of fermenting the sugars contained in both sugarcane juice and molasses. Initially, we process the sugarcane used in ethanol production the same way that we process sugarcane for sugar production. The molasses resulting from this process is mixed with clear juice and then with yeast in tanks, and the by-product resulting from the yeasting process, called “yeasted wine,” has an ethanol content of approximately 7% to 9%. After the yeasting process, which takes approximately ten hours, the yeasted wine is centrifuged, so that we can separate the yeast from the liquid. We use the separated yeast in the ethanol production process. We then boil the yeasted wine at different temperatures, which causes the ethanol to separate from other liquids. Hydrous ethanol is produced after different distillation stages. In order to produce anhydrous ethanol, hydrous ethanol undergoes a dehydration process. The liquid remaining after these processes is called vinasse, a by-product we use as fertilizer in our sugarcane fields. After the distillation and dehydration processes, we produce hydrous, anhydrous, neutral and industrial ethanol, and store the ethanol in large tanks.

The ethanol production flow can be summarized as follows:

• Preparation of the juice. The fermentation is fed with a juice composed of approximately 20% sugar, which is prepared with juice (from the treatment), molasses (from sugar production) and water. This juice must be cooled to approximately 30°C.

• Fermentation. The fermentation of the juice is the result of the action of yeast, which first inverts the sucrose to glucose and fructose (monosaccharide), and then converts the monosaccharide into ethanol and carbon dioxide. This reaction occurs in a fermenter, which is fed with juice and yeast.

• Centrifuging. After the fermentation, the resulting product is carried to centrifuges that separate the yeast from the beer, a solution of approximately 9%v/v (oGL) of ethanol.

• Treatment of the yeast. The yeast that comes from the centrifuges is treated with sulfuric acid and returned to the fermenter tank to be utilized again.

• Distillation. The beer is distilled in a sequence of distillation columns, which separate the water from the ethanol. This process occurs basically due to the differences of ethanol’s and water’s ebullition temperatures. In order to produce hydrous ethanol, two columns are used to achieve the concentration of 94%v/v (oGL) ethanol. From the first column, a slop called vinasse is obtained, which is used as a fertilizer in the sugarcane fields.

• Dehydration. In order to produce anhydrous ethanol, two more columns are used to achieve the concentration of 99%v/v (oGL) ethanol. In the first column, the excess of water is separated with the aid of cycle-hexane.

Ethanol Production Capacity and Output

Our current annual ethanol production capacity is approximately 2.6 billion liters. We were the largest producer of ethanol in Brazil in the fiscal year ended December 31, 2017, producing approximately 2.2 billion liters of ethanol, representing 8.6% of the total ethanol production in Brazil’s central-south region, according to UNICA. We are one of the largest exporters of ethanol in the world, having sold abroad R$2.7 billion including trading in the foreign markets, having exported 1.2 billion liters in the fiscal year ended December 31, 2017 and 1.5 billion liters in the fiscal year ended December 31, 2016.

Cogeneration

Raízen Energia currently has an installed energy capacity of 981 MW per year from our 26 mills, of which 13 mills sold their excess energy to the Brazilian energy grid. We view our cogeneration business as strategic since it generally allows for a stable cash flow stream across commodity cycles, helping to reduce the volatility of our cash flows and operations.

57

Energy Cogeneration Highlights	As of and for Fiscal Year Ended
	December 31, 2017		December 31, 2016		December 31, 2015
Energy sold (MWh)		3,520.7		2,871.9		2,611.2
Net sales (R$ million)(1)		884.3		520.5		554.9

(1) Raízen Energia is accounted for under the equity method, therefore, net sales are not consolidated in the Company’s statement of profit or loss and other comprehensive income. See “—E. Supplemental Information About Joint Venture.”

Alternative sources of electricity, such as cogeneration from sugarcane bagasse, have become increasingly important within the Brazilian hydro-dependent energy matrix, particularly because the harvest period for sugarcane coincides with generally drier periods for hydraulic energy, when the overall energy supply is, therefore, more constricted. We are self-sufficient for our energy needs. In the fiscal years ended December 31, 2017, 2016 and 2015, we sold 3,520.7 MWh, 2,871.9 MWh and 2,611.2 MWh, respectively, of energy to third parties. Our main customers, besides the energy sold to the Brazilian grid, are utility companies. In the fiscal year ended December 31, 2017, approximately 80% of our excess cogeneration volume was sold through long-term contracts.

Seasonality

Raízen Energia is subject to the seasonality of the annual sugarcane harvesting period in the Central-South region of Brazil, which begins in April or May and ends in November or December. This creates fluctuations in our inventory, usually peaking in December to cover sales between crop harvests (i.e., January through March), and a degree of seasonality in gross profit. See also “Item 5. Operating and Financial Review and Prospects—Principal Factors Affecting Our Results of Operations—Seasonality.”

Regulation

Raízen Energia is subject to several Brazilian federal, state and municipal environmental protection and health and safety laws and regulations governing, among other things, the generation, storage, handling, use, transportation and discharge of hazardous materials into the ground, air and water as well as regulation concerning electricity generation. Below is a summary of the principal rules and regulations to which Raízen Energia is subject.

Permits. Certain environmental laws require us to obtain from governmental authorities permits, licenses and authorizations to install and operate our mills, to burn sugarcane and to perform other activities.

We are subject to the regulations of the pollution control and remediation agencies of several Brazilian states, such as:

• Environmental Company of the state of São Paulo (Companhia Ambiental do Estado de São Paulo—CETESB);

• Environmental Agency of the State of Goiás (Secretaria de Meio Ambiente, Recursos Hídricos, Infraestrutura, Cidades e Assuntos Metropolitanos—SECIMA); and

• Environmental Institute of the state of Mato Grosso do Sul (Instituto de Meio Ambiente do Mato Grosso do Sul—IMASUL).

Environmental Licensing of Raízen. We operate mills, transport facilities and numerous warehouses. CONAMA is the government agency responsible for issuing rules and resolutions on environmental licensing at a national level. Environmental licensing is required for the development of new facilities and for alterations in existing operations. Environmental licenses must be periodically renewed.

Sugarcane Burning. The state of São Paulo and certain municipal governments have established laws and regulations that limit or eliminate the burning of sugarcane entirely. We have voluntarily signed the Agro-Environmental Sugarcane Protocol, which establishes accelerated deadlines for the reduction of sugarcane burning.

58

Brazilian Forestry Code. We are subject to the Brazilian Forest Code, which prohibits land use in certain permanently protected areas, and obligates us to maintain and register a forest reserve in each of our rural landholdings covering from 20% to 80% of the total area of such land, known as “Legal Reserve.”

Environmental Liabilities. We are involved in certain administrative and judicial proceedings for alleged failure to comply with environmental laws and regulations (especially relating to environmental damages caused by sugarcane burning and contaminated areas). The Brazilian Federal Constitution provides for three different types of environmental liabilities: (1) civil, (2) administrative and (3) criminal. Non-compliance with environmental law is subject to administrative, civil and/or criminal sanctions, regardless of the civil impacts such as the obligation to repair, compensate or indemnify any damages caused to the environment or third parties. Public attorneys’ offices, foundations, state agencies, state-owned companies and environmental protection associations are all authorized by law to file public civil actions seeking compensation for environmental damages.

Electricity Regulation. The Brazilian power industry is regulated by ANEEL, a federal regulatory agency, in accordance with the general guidelines set forth by the Ministry of Mines and Energy. In order to perform power generation activities, the power agent must obtain authorizations granted by ANEEL or execute concession and permission agreements with the Brazilian government through ANEEL. The activities related to generation and commercialization of electricity performed by Raízen Energia are subject to ANEEL’s supervision. Pursuant to Law No. 9,427 dated December 26, 1996 and ANEEL’s Resolution No. 63/2004, within the scope of its powers of inspection of electrical energy plants and services, ANEEL may impose penalties (including warnings, fines, temporary suspension of the right to participate in bidding procedures for new concessions, licenses or authorizations and forfeiture) on power industry participants based on the nature of its relation with the agency (concessionaires or agents who hold permission or authorization) and the materiality of the infraction. In case of fines, the limit of 2.0% of the revenue of the concessionaire in the 12-month period preceding any assessment notice must be respected or, for independent producers or self-producers (authorized agents), 2.0% of the estimated amount of energy produced in the same period. In addition, pursuant to ANEEL’s Resolution No. 63/2004 some infractions may result in fines related to the failure of the agent in requesting ANEEL’s prior approval to certain conduct, including the following:

• entering into certain related party transactions, pursuant to ANEEL’s Resolution No. 699/2016;

• sale or assignment of the assets related to services rendered as well as the imposition of any encumbrance (including any security, bond, guarantee, pledge and mortgage) on them or any other assets related to the concession or permission, or the revenues of the electricity services;

• changes in corporate control of the holder of the authorization, permission or concession, as per terms of ANEEL’s Resolution No. 484/2012; and

• as applicable, submit to ANEEL projects of electric works and plants and their modifications, as well as proceed with its execution in disagreement with the project approved and with the established scheduled.

Comgás (Natural Gas Distribution)

Overview

Comgás is Brazil’s largest distributor of piped natural gas, with a network reaching over 15,900 kilometers and delivering natural gas to more than one million residential, commercial and industrial consumers in over 88 cities. The Comgás concession area covers approximately 26% (according to the IBGE) of Brazil’s GDP, including approximately 180 municipalities in the metropolitan areas of São Paulo, Campinas and Santos as well as the Paraíba Valley.

We are the largest natural gas distributor in Brazil, with approximately 30% market share in Brazil in terms of volume sold in 2017, according to ABEGAS. We believe the prospects for future availability of natural gas in Brazil are positive based on expected exploration of carbon deposits discovered in the pre-salt layer offshore of Brazil’s coast. Comgás’ supply of natural gas is currently sourced primarily from Petrobras, with contracts in Bolivia and Brazil having been entered into. Our natural gas supply agreement with Petrobras that is sourced out of Bolivia comes due in 2019 and we cannot assure you that it will be renewed. See “Item 3. Key Information––D. Risk Factors—Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate—Our business would be materially adversely affected if operations at our transportation and distribution facilities experienced significant interruptions. Our business would also be materially adversely affected if the operations of our customers and suppliers experienced significant interruptions.”

59

Comgás Highlights	As of and for Fiscal Year Ended
	December 31, 2017		December 31, 2016		December 31, 2015
Natural gas sold (million cbm)		4,292.9		4,323.0		5,210.9
Net sales (R$ million)		5,537.9		5,657.2		6,597.0

Regulation

The National Agency of Petroleum, Natural Gas and Biofuels, or the “ANP,” is responsible for the control, supervision and implementation of the government’s oil, gas and biofuel policies. The ANP regulates all aspects of the production, distribution and sale of oil products in Brazil, including product quality standards and minimum storage capacities required to be maintained by distributors and is also responsible for establishing the limits of oil-based fuel volume purchased by distributors based on their storage capacity.

In addition to the regulation by ANP, Comgás’ activities are also supervised and regulated by ARSESP, with which it maintains continuous dialogue through its directorate for Regulatory and Institutional Affairs, in order to enhance or formulate industry policies. In light of the approach shown by regulators in recent years, Comgás does not believe that there will be any sudden changes that may affect its business.

Moove

Moove is responsible for the manufacturing and distribution of passenger vehicle lubricants, commercial vehicle lubricants, industrial lubricants and special application products such as greases, cutting oils and car care products under the Mobil and Comma brands in Brazil, Bolivia, Uruguay, Paraguay, Spain, and in specific sales channels in the United Kingdom and Asia.

Moove Highlights:	As of and for Fiscal Year Ended
	December 31, 2017		December 31, 2016		December 31, 2015
Volume of lubricants sold (thousand liters)		347.8		328.9		316.9
Net sales (R$ million)		2,129.5		1,883.7		1,751.7

We have a wholly-owned lubricants oil blending plant, located in Rio de Janeiro, with an annual production capacity of 2.2 million barrels of lubricants per year, and a pier facility that allows us to import base stocks. We produce over 600 different lubricants, and purchase more than 400 raw materials, including basic oils and additives.

We sell our lubricant products, mainly through distributors and direct sales to industrial customers, as well as to wholesale customer accounts and car and motorcycle dealerships. We also produce and sell lubricants for customers such as Toyota, John Deere, Caterpillar, Honda and SKF.

We have exclusive distribution rights for Mobil brand products in Bolivia, Paraguay and Uruguay following the purchase of ExxonMobil’s lubricant distribution business in these three countries in 2011.

In July 2012, we acquired Comma Oil and Chemicals Limited, which reinforced our strategy to enter into the European lubricants and specialties markets. As a result, we acquired finished lubricants and the manufacture and sale of chemicals to third parties, all of Comma’s assets at the Gravesend site in Kent, England, as well as ownership of Comma’s trademarks and brand names. In addition, agreements will be in place to allow Comma to continue to distribute select Mobil-brand lubricants into specific sales channels in the United Kingdom and to continue to manufacture and distribute a range of seasonal and ancillary automotive products to ExxonMobil.

60

We have exclusive distribution rights for Mobil brand products in Bolivia, Paraguay and Uruguay following the purchase of ExxonMobil’s lubricant distribution business in these three countries in 2011. Since December 2016, Moove has had the exclusive distribution rights for Mobil brand products in Spain and, more recently, in the UK, through the Stanbridge acquisition.

Our lubricants business is not subject to significant seasonality. However a significant proportion of our raw material purchases are invoiced in U.S. dollars and we hedge part of our shipments of base oils against variations in exchange rates.

Regulation

Moove is subject to substantially the same regulation by the same regulatory bodies to which our fuel distribution business, Raízen Combustíveis, is subject. See “—Raízen Combustíveis (Fuel Distribution).”

Cosan Logística

Overview

Our logistics operations are operated through Cosan Logística, which holds our interest in Rumo see “—A. History and Development of the Company.” Rumo offers an integrated logistics solution to agricultural commodity producers located in the central-south region of Brazil by transporting produce from the mills and depots by truck or rail to be loaded and stored in our port facility at the Port of Santos. Rumo also offers warehousing services.

Following Rumo’s merger with ALL which was completed on April 1, 2015, Rumo has expanded its offering of logistics services, including, among other things, by providing port handling services. Furthermore, Rumo acquired control of ALL’s former concessions which include the main railroads between the sugar and grain producing areas of the central-south region of Brazil and the Ports of Santos, Paranaguá, São Francisco and Rio Grande. As a result, Rumo now operates in the states of Mato Grosso and São Paulo as well as the southern region of Brazil where four of the most active ports in the country are located and through which most of Brazil’s grain production is exported. Moreover, Rumo started operating twelve main inland terminals, either directly or through partners. For further information, see “—A. History and Development of the Company.”

The following table sets for the certain financial and other information of Rumo for the periods indicated:

Logistics Highlights:	As of and for Fiscal Year Ended
	December 31, 2017		December 31, 2016		December 31, 2015(1)
Transported volume (million RTK)		49,690.5		40,270.4		44,908.8
Port elevation volume (thousand tons)		13,133.0		13,113.7		11,681.6
North operations (R$ million)		4,439.7		3,651.5		2,925.1
South operations (R$ million)		1,283.1		1,097.7		888.5
Container operations (R$ million)		223.5		265.4		224.3
Net sales (R$ million)		5,946.3		5,014.6		4,037.9

(1) As the acquisition of ALL occurred on April 1, 2015, the result of information with segments are presented in the North Operations, composed of the railway operations, transshipment and port elevation in the areas of the Company’s concession of Malha Norte and Malha Paulista.

Currently, Rumo owns and operates a large asset base, including a rail network consisting of four concessions that extend over approximately 12,000 kilometers of railway lines, more than 1,000 locomotives, over 30,000 rail cars, as well as distribution centers and warehousing facilities. Rumo provides efficient and complete logistics services to its clients through its operation of 12 transshipment terminals, either directly or through partnerships, which have a static storage capacity of approximately 900,000 tons, and where we store grains, sugar and other commodities. At its most important terminal, the logistics complex of Rondonópolis (in the state of Mato Grosso), Rumo has the capability to load over one million tons of grains per month. Moreover, Rumo controls two port terminals in Santos in the state of São Paulo, and holds equity interests in four other port terminals, three of which are in the port of Santos in the state of São Paulo and one in the state of Paraná, with a static storage capacity of approximately 1.3 million tons and a total loading capacity of approximately 29 million tons per year. The real estate Rumo leases in connection with its concessions contains areas available for construction and development of warehouses and logistics terminals, which makes it possible for Rumo to expand its operations and improve our logistics and other services. For example, the Grain Terminal of Guarujá (TGG) in the port terminal in Santos, in which Rumo currently has a 10% equity interest, is a significant port project that has been constructed and has the capacity to handle approximately eight million tons of grain per year.

61

Operational Segments

Rumo organizes its operations into three segments that correspond to the main markets in which it operates: (1) the north operations segment, or “Northern Operations,” comprising the Malha Norte and Malha Paulista rail concessions, Rumo’s transshipment terminals located in the states of Mato Grosso and São Paulo, and Rumo’s port operation in Santos, (2) Rumo’s south operations business segment, or “Southern Operations,” comprising Malha Oeste and Malha Sul, as well as Rumo’s transshipment terminals in the state of Paraná, and (3) Rumo’s container operations business segment, or “Container Operations,” which comprise the operations of Brado Logística and other container operations.

Major Customers

The majority of cargo Rumo transports is for the agricultural commodities industry. Rumo’s major clients are export companies participating in this market, such as Amaggi, ADM, Bunge, Cargill, Louis Dreyfus and Raízen. In the fiscal year ended December 31, 2017, Bunge accounted for 15% of Rumo’s total net revenue from services, while Rumo’s six major clients accounted for 52.5% of Rumo’s total net revenue from services. In the fiscal year ended December 31, 2016, Bunge accounted for 17.6% of Rumo’s total net revenue from services, while Rumo’s six major clients accounted for 51.6% of Rumo’s total net revenue from services in the same period. Bunge is the principal customer of Rumo’s Northern Operations and Southern Operations and is active in agricultural commodities, especially corn, soy and derivatives thereof, loading cargo in transshipment terminals destined for ports which Rumo operates.

Rumo’s major clients in the rail sector are export companies such as Amaggi, ADM, Bunge, Cargill, Louis Dreyfus and Raízen, which jointly accounted for 54.8% of Rumo’s net revenue from services from the rail sector in 2016 and 46.4% in 2017. Bunge alone accounted for 21% and 14.5% of Rumo’s net revenue from services from the rail sector in each of 2016 and 2017, respectively.

Rumo’s major clients in the port elevation sector include Bunge, Czarnikow, Cofco, Wilmar, Raízen and Sucden, which jointly accounted for 68.9% of our net revenue from services from the port elevation sector in 2016 and 52.3% in 2017. Raízen alone accounted for 24.1% of Rumo’s net revenue from services in the port elevation sector in 2016 and 17.9% in 2017.

Seasonality

Rumo is subject to the seasonality that influences the sugarcane and grain harvest. During the peak months of the harvests, there is higher demand for transport and logistics operations. Rumo is also subject to the risk that sugarcane mills may change their production mix in favor of ethanol if the relative prices of the two products swing that way. This could reduce the demand for sugar logistics and transport. See also “Item 5. Operating and Financial Review and Prospects—Principal Factors Affecting Our Results of Operations—Seasonality.”

Regulation

Port Regulation

The Brazilian constitution provides that the federal government, directly or by delegation to third parties, shall exploit port activities in Brazil. In 2001, the National Waterway Transportation Agency (Agência Nacional de Transportes Aquaviários), or “ANTAQ,” was created in order to regulate the Brazilian port industry and to enter into the relevant concession and adhesion agreements regarding the provision of port services.

62

Until December 6, 2012, port operations in Brazil were governed by Federal Law No. 8,630, dated February 25, 1993, or the “Ports Modernization Law,” which provided the legal framework applicable to the exploitation of the publicly-owned port terminals and facilities in Brazil. In view of the need to improve the applicable legislation, the Brazilian government implemented Law 12,815 dated June 5, 2013, or the “New Ports Law,” that expressly revoked the Ports Modernization Law and established a new legal framework with respect to port operations in Brazil.

Before the enactment of the Ports Modernization Law, most of the port terminals were exploited by the government. The Ports Modernization Law was enacted to enable the participation of private investors in the Brazilian port industry by the creation of different port terminal exploitation models: public and private.

The Ports Modernization Law assured to any private party the right to construct, reform, expand, improve, lease and operate a public port terminal located within the “organized port area,” which are designated areas where ports must serve the public interest and the need for port service, subject to an authorization from the relevant authority. The development of port activities in an organized port area should be preceded by a competitive bidding process and the execution of a concession agreement with the federal government.

In the case of Rumo, the Docks Company of the state of São Paulo (Companhia Docas do Estado de São Paulo), or “CODESP,” granted us the right to exploit public terminals at the Port of Santos. The respective concessions agreements are dated as from 1996 and 2001. Accordingly, such agreements are governed by the Ports Modernization Law.

Rumo was qualified as a port operator under the Port Modernization Law and is currently subject primarily to the regulation of CODESP, which acts under the regulation of ANTAQ.

Public ports are governed by Law 12,815 dated June 5, 2013 and regulations that are still to be published by the Government in order to complement the provisions of Law 12,815 dated June 5, 2013. Law 12,815 dated June 5, 2013 does not provide for the need of adjustments of the terms of any concession agreements in force, requiring adjustments to be made only if both parties intend to extend the agreement. As a result, until new regulation provides otherwise, the concession agreements entered into by and between CODESP and us shall not be amended in order to adjust its terms to Law 12,815 dated June 5, 2013.

Rail Transportation Regulation

Following Rumo’s merger with ALL, we are subject to the regulation of the ANTT, which is responsible for monitoring road and rail transport operations and the federal concessions of road and rail infrastructure in Brazil. Previously, we were indirectly subject to such regulation due to the agreements we had in place with ALL.

Rail transportation activities in Brazil are subject to a wide variety of laws and regulations, such as: Law 8,987 dated February 13, 1995 (the “Concession Law”); ANTT Resolution 3,694 dated July 14, 2011 (which approves Regulations for Users of Rail Freight Services); ANTT Resolution 3,695 dated July 14, 2011 (which approves the Regulations of “Right of Passage” and “Mutual Traffic” operations); ANTT Resolution 3,696 dated July 14, 2011 (which approves the regulations for agreeing to production targets per stretch of railway and safety targets for concessionaires).

The Concession Law requires that the granting authority and concession holder enter into a concession agreement regulating the terms of such exploration and setting forth the terms applicable to the performance of the services (including with regards to the applicable penalties).

Waterborne Transportation Regulation

In Brazil, there are two main regulatory regimes affecting waterborne transportation: (i) the concession regime, which regulates the exploitation of publicly-owned port terminals and the leasing of publicly-owned terminals and (ii) the authorization regime, relating to new private port terminals and facilities. The main legislation applicable to this sector is: Law 12,815 dated June 5, 2013 (Ports Law) and Decree 8,033 of June 27, 2013.

63

Environmental Regulation

We are subject to various Brazilian federal, state and municipal environmental laws and regulations, among other matters, regarding to: (1) the issuance and renewal of valid environmental permits and authorizations; (2) the generation, storage, handling, use and transportation of hazardous materials; (3) the wildlife and natural resources preservation; (4) the protection of cultural and historic sites; (5) the emission and discharge of hazardous materials into the ground, air or water; and (5) the health and safety of our employees.

We are also required to obtain environmental permits and/or authorizations (such as installation and operation permits as well as permits for vegetation suppression and the storage, use and transportation of hazardous products) from governmental authorities for certain aspects of our operations. Failure to obtain environmental permits or comply with the conditions under which such permits are issued could subject us to criminal, administrative and/or civil liabilities. These laws, regulations and permits often require us to purchase and install pollution control equipment or to make operational changes to mitigate actual or potential impacts on the environment and/or health of our employees. In addition, Brazilian environmental laws restrict our ability to obtain financing from public entities in the event of a breach of certain environmental protection obligations. Any violations of these laws and regulations or permit conditions can result in substantial fines, criminal sanctions, revocation of operating permits and/or shutdowns of our facilities.

Under Brazilian environmental laws, we could be held strictly liable for all of the costs relating to any contamination at our or our predecessors’ current and former facilities and at third-party waste disposal sites used by us or any of our predecessors (propter rem liability). We could also be held responsible for any and all consequences arising out of human exposure to hazardous substances, such as pesticides, herbicides, soil or groundwater contamination.

We are party to a number of administrative and judicial proceedings for alleged failure to comply with environmental laws, which may result in fines, suspension of activities or other adverse effects on our operations. Infractions that give rise to administrative proceedings may also lead to civil or criminal claims against us.

Rail Concessions

We conduct our rail activities through the following concession agreements: (1) the concession agreement entered into on December 30, 1998 involving Malha Paulista, expiring in 2028 (which may be extended for a further 30 years); (2) the concession agreement entered into on May 19, 1989 involving Malha Norte, expiring in 2079; (3) the concession agreement entered into on July 7, 1996 involving Malha Oeste, expiring in 2026; and (4) the concession agreement entered into on February 27, 1997 involving Malha Sul, expiring in 2027 (which may be extended for a further 30 years).

In September 2015, we filed formal requests for the renewal of the Malha Sul and Malha Paulista concession agreements with the ANTT. Such requests are currently under review by the ANTT. The request relating to the Malha Paulista concession is in a more advanced stage of analysis by the ANTT and our expectation is that such review will be completed during the course of 2018. The analysis of the Malha Sul renewal request should resume following the conclusion of the ANTT’s analysis of the renewal request relating to Malha Paulista.

The granting authority may unilaterally rescind all of our rail concession agreements prior to their expiration in the following circumstances:

• encampação, which is the takeover of the provision of the services by the granting authority by means of specific legal order and prior payment of indemnity;

• forfeiture, which means the complete or partial non-performance of the concession agreement or failure to comply with the financial terms of the concession agreement and the lease agreement (when there is one force);

• bankruptcy or dissolution of the concession holder; or

• cancellation of the bidding process.

64

The enforcement of any of the unilateral termination provisions of the concession agreement must be preceded by the relevant administrative proceeding with ANTT and may result in indemnity to us for assets that revert to the granting authority. As of the date of annual report, there is no fact enabling the application of any of the unilateral termination events of the concessions.

Risk Factors—Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate––The loss of Brazilian railway concessions may have a material adverse effect on our business.” and “Item 3. Key Information––D. Risk Factors—Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate–– Rumo may not obtain early renewals of the Rumo Malha Paulista S.A., or “Malha Paulista,” and Rumo Malha Sul S.A., or “Malha Sul,” concession agreements, currently under review by the ANTT, which may have a material adverse effect on Rumo’s investment plan and growth strategy.”

Port Lease Agreements

We lease 118,434.38 square meters of property located in the port of Santos (state of São Paulo), which has two docking cradles for loading sugar and solid agricultural bulk (corn and soy). We lease this property pursuant to lease agreement PRES-05/96, which matures on March 6, 2036. Pursuant to Article 57 of the Ports Modernization Law and Article 19 of Decree No. 8,033/2013, a renewal of the maturity for the Lease Agreement is not possible because the lease has already been renewed once. Pursuant to the lease agreement, we have an obligation to make investments totaling an estimated R$308 million, which we estimate to complete by February 2019.

We also hold equity interests in: (1) Terminal XXXIX and the adjacent areas for moving agricultural products and bulk as well as other goods capable of being transported in those port installations, through a port lease agreement due to expire in 2022; (2) facilities, equipment and track for rail transport of goods and import/export through the right and left banks of the port of Santos, by means of a lease agreement with Portofer Transporte Ferroviário Ltda. due to expire in 2025; (3) Terminal de Granéis do Guarujá (TGG) located on the left bank of the port of Santos, for the transport of solid and liquid bulk, through an area used by Malha Norte via a leasing agreement due to expire in 2022; and (4) Terminal Marítimo do Guarujá (TMG), located on the left bank of the port of Santos, mainly for the transport of solid and liquid bulk, through an area used by Malha Norte via a lease agreement due to expire in 2022.

There are ongoing legal proceedings regarding whether the lease agreements relating to Terminal XXXIX, Terminal de Granéis do Guarujá and Terminal Marítimo do Guarujá should be subject to the public procurement regime. These proceedings are currently under appeal in the Brazilian superior courts (Superior Tribunal de Justiça and Supremo Tribunal Federal). With regards to the Portofer lease agreement, there is an ongoing investigation by the Brazilian Federal Prosecutors’ Office, of a non-criminal nature, to assess the legal validity of the agreement.

If we fail to comply with the applicable regulatory rules or contractual obligations, our lease may be terminated early pursuant to the Concessions Law (Law No. 8,987/1995), which applies to port leases.

Competition

Fuel Distribution

In the fuel distribution business, we are subject to competition, both from companies in the industries in which we operate and from companies in other industries that produce similar products. Our competitors include service stations of large integrated oil companies, independent gasoline service stations, convenience stores, fast food stores, and other similar retail outlets, some of which are well-recognized national or regional retail systems. The Brazilian fuel distribution industry has consolidated significantly in recent years, with the three major distributors increasing their combined market share from 65.2% in 2000 to approximately 69.5% in 2017, according to ANP and considering all products.

According to Plural, former Sindicom, the top-three distributors in Brazil are: Petrobras, operating through the BR Distribuidora brand, Raízen, through the Shell brand and Ultrapar S.A., through the Ipiranga brand. The main competitive factors affecting the retail marketing operations include site location, product price, selection and quality, site appearance and cleanliness, hours of operation, store safety, customer loyalty and brand recognition.

65

Sugar, Ethanol and Cogeneration

The sugar industry in Brazil has experienced increased consolidation through merger and acquisition activity during the past decade. Most of this activity has involved companies and facilities located in the central-south region of Brazil, one of the most productive sugar producing regions in the world. Despite this recent wave of consolidation, the industry remains highly fragmented with more than 365 sugar mills and 135 company groups participating, according to MAPA.

We also face competition from international sugar producers. According to UNICA, we are the largest sugar producer in Brazil and the largest sugar exporters in the world with 4.3 million tons of sugar produced in the 2016/2017 harvest, compared to Tereos (2 million tons of sugar produced in the 2016/2017 harvest) and Südzucker AG of Germany (with 4.8 million tons of sugar produced in the 2016/2017 harvest). These producers, however, are the beneficiaries of considerable governmental subsidies in their principal sales markets.

We also face competition from international ethanol producers that use other ethanol sources, such as corn and sugar beet, for the generation of fuel ethanol.

Natural Gas

Comgás’ concession area covers approximately 26% of Brazil’s GDP, including approximately 180 municipalities in the metropolitan areas of São Paulo, Campinas and Santos as well as the Paraíba Valley. Comgás distributes natural gas for residential, commercial and industrial customers, and also supplies gas for use as fuel for vehicles and electricity generation. For the residential and commercial customers, Comgás holds exclusivity rights within its area of concession. For industrial customers, Comgás has exclusive distribution rights until 2029. Comgás faces competition from electricity concessionaires, oil and ethanol producers in its activities.

Logistics

Companies active in the Brazilian railroad transport market generally provide logistics services in their respective regions, with regions being allocated to various companies based on the public concessions granted by the ANTT. The necessity of obtaining a concession from the ANTT represents a barrier to the entry of new competitors into the market given that each concession area is granted to a single operator. As there are currently no parallel rail tracks in the Brazilian railway network, the competition in the market in which we operate primarily derives from truck transportation, which can compete for the same freight as rail operators. Clients generally select a mode of transportation based on the best terms and conditions offered to them in the market.

The main factors on which transport companies compete are the freight rates charged, efficiency and volume. Given our offering of advantageous prices coupled with our significant transport capacity and greater efficiency, we believe we have significant opportunities to increase our current market share within the areas in which we operate and that we are in a better strategic position than our competitors to seize the growth opportunities in these industries.

Historically, railroad freight prices have varied in conjunction with road freight prices. Freight prices in the road transportation market have increased significantly in the past years, as illustrated below. We expect this increase to also benefit railroad operators such as us, given the correlation between road and rail freight prices.

66

Patents, Licenses, Contracts and Processes

In Brazil, ownership of trademarks can be acquired only through a validly approved registration with the National Institute of Intellectual Property (Instituto Nacional de Propriedade Industrial, or “INPI”), the agency responsible for registering trademarks, patents and designs in Brazil. After registration, the owner has exclusive rights of use of the trademark throughout Brazil for a ten-year period that can be successively renewed for equal periods.

As of the date of this annual report, we own 297 trademarks in Brazil, 96 of which are owned by Cosan S.A., 26 of which are owned by Cosan Logística, with the remaining 175 owned by other companies of the Cosan group. All material trademarks for our business are registered or have been submitted to INPI by us or our affiliates.

Research and Development

Our main research and development activities for the fiscal years ended December 31, 2017, 2016 and 2015 concentrated in the following key areas:

• We engage CanaVialis S.A., or “CanaVialis,” to provide us with access to its sugarcane genetic improvement program specifically tailored to Raízen Energia’s mills. CanaVialis, which is a subsidiary of Monsanto, is a privately owned firm focused on the genetic improvement of sugarcane. We benefit from their support services and use of their bio factory, which allows us to decrease the amount of time required for seedling production and grants us access to new, improved sugarcane varieties through their genetic improvement program. CanaVialis also conducts field trials and region-specific genetic selection programs to develop sugarcane varieties for our greenfield projects for the construction of new sugarcane mills.

• Raízen also invests in innovation in the ethanol manufacturing process. Raízen has an interest in Shell’s commercialization rights of Iogen Energy, which conducts research into advanced fuels, including ethanol extracted from the cellulose of sugarcane and other plants.

• We conduct research and development into renewable base oils through Novvi S.A., a Joint Venture between Cosan and Amyris formed in 2011. Novvi was established for the worldwide development, production and commercialization of renewable base oils made from Biofene, Amyris’ renewable farnesene.

Our total research and development expenditure amounted to R$2.9 million in the fiscal year ended December 31, 2017, R$3.7 million in the fiscal year ended December 31, 2016 and R$0.7 million in the fiscal year ended December 31, 2015, respectively.

C. Organizational Structure

We are an integrated energy and infrastructure company and, when considered together with the Joint Venture, a Brazilian market leader in fuel distribution, sugar and ethanol production, natural gas distribution and logistics. Our main operations include: (1) the distribution of fuels in the Brazilian market through Raízen Combustíveis, our downstream Joint Venture company; (2) the production and sale of sugar and ethanol and the cogeneration of electricity from sugarcane bagasse through Raízen Energia, our upstream Joint Venture company; (3) the distribution of piped natural gas in part of the state of São Paulo through our subsidiary Comgás, which has been consolidated since November 2012; (4) logistics services including transportation, port loading and storage of sugar, through our indirectly owned subsidiary Rumo; (5) the production and distribution of lubricants under the Mobil licensed trademark in Brazil, Bolivia, Uruguay and Paraguay, in addition to the European and Asian markets under the Comma brand; and (6) certain other investments, or “Cosan Corporate.”

At October 1, 2014, the Partial Spin-off of the “Rumo” segment of Cosan to “Cosan Logística S.A.” was approved by Cosan’s shareholders, becoming fully effective on October 6, 2014. This Partial Spin-off does not affect the consolidated financial statements of Cosan Limited.

67

A list of the Company’s subsidiaries is included in note 3 of our audited consolidated financial statements for the fiscal years ended December 31, 2017, 2016 and 2015 attached hereto. See also Exhibit 8.1 to this annual report, which contains a list of our subsidiaries.

Until the adoption of IFRS 11, these investments were accounted for using the proportional consolidation method. Upon the adoption of IFRS 11 in the transition period ended December 31, 2013, these investments are accounted for under the equity method. The Joint Venture consists of three separate legal entities:

• Raízen Combustíveis S.A.: a downstream company, which conducts the supply, distribution and sale of fuels in Brazil. In 2017, the resulting company had a network of approximately 6,272 fuel stations throughout Brazil. Cosan and its subsidiaries and Shell and its affiliates likewise each own 50% common equity interest in this entity. In this entity, however, Cosan and its subsidiaries own 50% minus one of the voting shares, whereas Shell and its affiliates own 50% plus one of the voting shares. Cosan and its subsidiaries and Shell and its affiliates also hold preferred shares bearing preferential dividend rights in certain circumstances if certain contingent targets are met.

• Raízen Energia S.A.: a sugar and ethanol company, which, among other things, conducts the production of sugar and ethanol, as well as all cogeneration activities. Cosan and its subsidiaries and Shell and its affiliates each own 50% common equity interest in this entity. In addition, Cosan and its subsidiaries own 50% plus one share of the voting shares (and preferred shares bearing preferential dividend rights in certain circumstances), whereas Shell and its affiliates own 50% minus one of this entity’s voting shares.

• Raízen S.A.: a management company, which is the Joint Venture’s face to the market and facilitates the building of a unified corporate culture. Cosan and its subsidiaries and Shell and its affiliates each own 50% of the equity and voting interests in this company.

D. Property, Plant and Equipment

For more information related to property, plant and equipment see note 15 of our audited consolidated financial statements for the fiscal years ended December 31, 2017, 2016 and 2015 attached hereto. See also “—Capital Expenditures” for a description of our ongoing expansions and renovations of our property, plant and equipment.

We present a summary below of our material tangible fixed assets, including investment properties and intangible assets (concessions), by segment:

Raízen Combustíveis

Raízen Combustíveis distributes fuels through 68 distribution terminals to approximately 6,272 service stations throughout Brazil under the Shell brand and also has 68 airport terminals supplying aviation fuel.

68

Raízen Energia

Raízen Energia operates 26 mills with a crushing capacity of 73 million tons and 981 MW of annual generation capacity. All of these facilities are located in the central and southeastern regions of Brazil, which is one of the world’s most productive sugarcane regions, primarily because of its favorable soil, topography and climate, nearby research and development organizations and logistics infrastructure.

Comgás

Comgás is Brazil’s largest natural gas distributor with a pipeline network of over 15,912 kilometers, supplying natural gas to 1.8 million residential, commercial and industrial consumers in over 88 cities. Its concession area accounts for approximately 26% of Brazil’s GDP, covering approximately 180 municipalities in the metropolitan areas of São Paulo, Campinas, Santos and the Paraíba Valley.

Moove

Moove has a production plant located on the Ilha do Governador, Rio de Janeiro, with a production capacity of 2.2 million barrels of lubricants per year, storage capacity for base oils and lubricants (620,000 barrels) and a pier facility for docking ships of up to 20,000 tons.

Cosan Logística

Rumo concluded the ALL Acquisition on April 1, 2015 and is Brazil’s largest railroad-based logistics operator in terms of total volume transported, providing rail transport logistics, port handling and warehousing services. We operate in the states of Mato Grosso and São Paulo as well as the southern region of Brazil. According to MDIC and IBGE data, our rail network extends over an area that accounts for approximately 80% of Brazil’s GDP, where four of the most active ports in the country are located and through which most of Brazil’s grain production is exported.

Rumo owns and operates a large asset base, including a rail network consisting of four concessions that extend over approximately 12,000 kilometers of railway lines, over 1,000 locomotives, over 25,000 rail cars, as well as distribution centers and warehousing facilities. Rumo provides efficient and complete logistics services to its clients through its operation of 12 transshipment terminals, either directly or through partnerships, which have a static storage capacity of approximately 900,000 tons, and where it stores grains, sugar and other commodities. At its most important terminal, the logistics complex of Rondonópolis (in the state of Mato Grosso), Rumo has the capability to load over 1 million tons of grains per month. Moreover, it controls two port terminals in Santos in the state of São Paulo, and holds equity interests in four other port terminals, three of which are in the port of Santos in the state of São Paulo and one in the state of Paraná, with a static storage capacity of approximately 1.3 million tons and a total loading capacity of approximately 29 million tons per year. The real estate it leases in connection with its concessions contains areas available for construction and development of warehouses and logistics terminals, which makes it possible for Rumo to expand its operations and improve its logistics and other services. For example, the Grain Terminal of Guarujá (TGG) in the port terminal in Santos, in which Rumo currently has a 10% equity interest, is a significant port project that has been constructed and has the capacity to handle approximately 8 million tons of grain per year.

The transportation of agricultural commodities, primarily for export, represented approximately 83.4%, 82% and 80% of Rumo’s transported volume in the fiscal years ended December 31, 2017, 2016 and 2015, respectively, while transportation of industrial products represented approximately 16.6%, 18% and 20% of Rumo’s transported volume in the same periods, respectively. In addition, in the fiscal years ended December 31, 2017, 2016 and 2015, approximately 60.1%, 70% and 68%, respectively, of Rumo’s transported volume derived from the transportation of grains.

We believe that Rumo’s asset base allows it to provide transportation services to various customers, mainly for agricultural commodities, which has made Rumo one of the primary agricultural logistics service providers in the Brazilian agricultural industry. We believe that the services Rumo provides are important to the development and growth of the country, as Brazil is one of the main producers and exporters of agricultural products in the world.

69

Rumo also provides intermodal transportation logistics services, which is the movement of freight via container using two or more modes of transportation (generally rail and truck). We believe that these methods of transportation reduce the costs of cargo handling, because containers are typically consolidated from trucks onto trains or ships that can carry mass loads, allowing for fuel efficiency.

Capital Expenditures

Our capital expenditure program is currently focused on the following areas:

Raízen Energia

Biological Asset and Intercrop Maintenance

Raízen Energia invests in maintaining and renewing sugarcane fields at approximately 70% of its total capital expenditures per year. Raízen Energia also invests every year in intercrop maintenance. The biological asset and intercrop maintenance capital expenditures totaled approximately R$898 million in the fiscal year ended December 31, 2017.

Operational and Other Projects Expenditures

Raízen Energia has several other investments that include health, safety and environmental initiatives, sustaining, ethanol and sugar logistics, harvest and planting mechanization, expansion through brownfield projects among other projects. An important part of these investments aims to increase the productivity and efficiency of its operations. The operational and other projects capital expenditures totaled approximately R$466 million in the fiscal year ended December 31, 2017.

Raízen Combustíveis

Raízen Combustíveis invests in maintaining and expanding infrastructure, including, among others, its service stations network expansion. The capital expenditure of Raízen Combustíveis in the fiscal year ended December 31, 2017 amounted to R$781 million, of which approximately 80% was invested in its service station network.

Comgás

Comgás has been investing in its network expansion and during the fiscal year ended December 31 2017, it invested R$460 million, of which approximately 60% was associated with expansion programs, approximately 30% was related to network support investments, and approximately 10% was related to administrative and software investments. In 2018, we expect to invest approximately R$450 to R$500 million, according to a similar distribution.

Cosan Logística

Rumo’s strategy is focused on investments in the renovation of assets, in particular its locomotives and railcar fleet, through the purchase of new rolling stock to replace assets in poor condition of use. The purpose of Rumo’s investment in rail tracks is to reduce its operating costs and maximize its transported volume. As result of Rumo’s ongoing efforts, Rumo is increasing capacity while reducing transit time along some of our major routes. During the fiscal year ended December 31, 2017, Rumo’s total investments in property, plant and equipment and intangible assets amounted to R$2,151 million in the aforementioned initiatives, including overhauling 233 km of tracks and, purchasing 772 railcars and 27 new locomotives. Approximately 65% of the capital expenditure mentioned above was invested in nonrecurring expansion projects and 35% in recurring projects.

The funds used by Rumo for making capital expenditures are generated from Rumo’s operating results and from financings and credit extended by private banks, as well as by publicly-owned banks such as BNDES. Since the beginning of Rumo’s rail operations, BNDES has been an important partner in the development of Rumo’s infrastructure, providing support through long-term credit lines in line with Rumo’s investment plan published in April 2015.

70

Rumo, together with certain third parties, have invested in the construction of a roof over one of its two port terminals in the port of Santos, in the state of São Paulo. This roof, which is still under construction, will make it possible to conduct cargo loading onto ships on rainy days. Historically, the city of Santos has had 120 days of rain per year during which the loading of ships is usually not possible. The construction of the roof and, together with other investments Rumo is making in the port terminal, is expected to increase the loading capacity of Rumo’s terminals to 19 million tons by the end of 2019.

E. Supplemental Information About Joint Venture

Upon the application of IFRS 11, the Company retrospectively changed the accounting for its investments in Raízen Combustíveis and Raízen Energia, classifying them as jointly-controlled entities (Joint Ventures) under the new standard. Although, Raízen Combustíveis and Raízen Energia are not consolidated in our financial statements (since March 31, 2013) we have included below a summary of business performance derived from note 5 (Operating segments) to our audited financial statements for the periods indicated.

The discussion in this section is based on a comparison of the audited fiscal year ended December 31, 2017 with the audited fiscal year ended December 31, 2016, and on a comparison of the audited fiscal year ended December 31, 2016 with the audited fiscal year ended December 31, 2015.

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

Net Sales

	For the Fiscal Year Ended December 31, 2017		For the Fiscal Year Ended December 31, 2016		% Variation
	(in millions of reais, except percentages)
Raízen Energia(1)		13,152.8		13,133.8		0.14	%
Ethanol		6,550.7		6,480.4		1.08	%
Sugar		5,377.4		5,794.8		(7.20	)%
Cogeneration		884.3		520.5		69.89	%
Other		340.4		338.1		0.68	%
Raízen Combustíveis(1)		72,789.1		68,143.0		6.82	%
Fuel		72,789.1		68,143.0		6.82	%

(1) Includes 100% of these entities’ net sales which upon the application of IFRS 11 are recorded in the “Equity income of jointly-controlled entity” line item in the consolidated statements of profit or loss and comprehensive income for the fiscal years ended December 31, 2017 and 2016.

The change in the various components consists of the following:

Raízen Energia

Raízen Energia’s sales in the fiscal year ended December 31, 2017 amounted to R$13,152.8 million, in line with net revenues of R$13,133.8 million the fiscal year ended December 31, 2016. Higher average electric energy prices on top of higher volumes sold generated an increase of 69.9% in cogeneration sales, reflecting better market prices in the period. This effect was partially offset by a 7.2% decrease in sugar sales, mainly due to lower international prices.

Raízen Combustíveis

Raízen Combustíveis’ net sales in the fiscal year ended December 31, 2017 increased from R$68,143.0 million to R$72,789.1 million, or 6.8%, as compared to the fiscal year ended December 31, 2017. This growth reflects higher volume sold, mainly gasoline and diesel, and higher prices of (i) gasoline (5%) and diesel (1%) adjusted by Petrobras; and (ii) ethanol (ESALQ base). This increase in prices and in volume sold is a result of the improvements in Brazil’s macroeconomic environment during the course of 2017.

Cost of Sales

	For the Fiscal Year Ended December 31, 2017			For the Fiscal Year Ended December 31, 2016			% Variation
	(in millions of reais, except percentages)
Raízen Energia(1)		(10,907.7	)		(9,967.5	)		9.43	%
Raízen Combustíveis(1)		(68,875.3	)		(64,445.9	)		6.87	%
Cost of Sales		(79,783.0	)		(74,413.4	)		7.22	%

(1) Includes 100% of these entities’ cost of sales which upon the application of IFRS 11 are recorded in the “Equity income of jointly-controlled entity” line item in the consolidated statements of profit or loss and comprehensive income for the fiscal years ended December 31, 2017 and 2016.

Raízen Energia

The cost of sales in the fiscal year ended December 31, 2017 increased 9.4%, or R$10,907.7 million, as compared to the fiscal year ended December 31, 2016, due mainly to higher resale and trading costs (26%) reflecting greater volumes in the sales mix, which has higher unitary cost.

Raízen Combustíveis

The cost of sales in the fiscal year ended December 31, 2017 increased 6.9%, or R$4,429.4 million, as compared to the fiscal year ended December 31, 2016. This increase is due to higher sales volume (2.9%) and increases in gasoline and diesel prices, according to the pricing policy implemented by Petrobras in October 2016 and higher logistics costs as a result of our supply strategy.

Selling Expenses

	For the Fiscal Year Ended December 31, 2017			For the Fiscal Year Ended December 31, 2016			% Variation
	(in millions of reais, except percentages)

Selling expenses		(2,149.0	)		(2,036.0	)		5.55	%

(1) Includes 100% of these entities’ cost of sales, which, upon the application of IFRS 11, are recorded in the “Equity income of jointly-controlled entity” line item in the consolidated statements of profit or loss and comprehensive income for the fiscal years ended December 31, 2017 and 2016.

Raízen Energia

Raízen Energia’s selling expenses increased R$70.5 million, or 9.6%, in the fiscal year ended December 31, 2017 as compared to the fiscal year ended December 31, 2016, due primarily to 7.2% higher expenses with freight. These higher freight expenses can be principally attributed to the higher volume of sales, driven primarily by ethanol resale and trading volumes, which increased by 40.2%.

Raízen Combustíveis

Raízen Combustíveis’ selling expenses increased to R$1,345.8 million, or 3.3%, in the fiscal year ended December 31, 2017, from R$1,303.3 million in the fiscal year ended December 31, 2016, due primarily to an increase of 19% in freight and logistics expenses, which partly offset by lower tax expenses when compared to 2016.

72

General and Administrative Expenses

	For the Fiscal Year Ended December 31, 2017			For the Fiscal Year Ended December 31, 2016			% Variation
	(in millions of reais, except percentages)

Raízen Energia

General and administrative expenses totaled R$618.1 million in the fiscal year ended December 31, 2017, an increase of 8.9% compared to the fiscal year ended December 31, 2016, primarily due to an increase in depreciation expenses which was attributable in the most part to a 27% increase in depreciation expenses recorded in connection with property, plant and equipment.

Raízen Combustíveis

General and administrative expenses totaled R$455.7 million in the fiscal year ended December 31, 2017, an increase of 1.8%, or R$8 million, compared to the fiscal year ended December 31, 2016, primarily due to the impact of inflation on general expenses.

The change in the various components consists of the following:

Raízen Energia

Raízen Energia’s sales in the fiscal year ended December 31, 2016 increased from R$11,080.9 million to R$13,133.8 million (or 18.5%), as compared to the fiscal year ended December 31, 2015, primarily due to higher average sugar and ethanol prices, reflecting better market prices in the period (mainly as a result of increased international prices and the depreciation of the real against the U.S. dollar) and an increase of 1.5% in sugar sales volume (related to the international market). This was offset in part by a decrease in ethanol sales volume, along with the opportunities to sell third-party products.

73

Raízen Combustíveis

Raízen Combustíveis’ net sales in the fiscal year ended December 31, 2016 increased from R$61,413.0 million to R$68,143.0 million, or 11%, as compared to the fiscal year ended December 31, 2015. This growth reflects higher gasoline sales volume and higher prices of (i) gasoline (6%) and diesel (4%) adjusted by Petrobras; and (ii) ethanol (ESALQ base). This was offset by a decrease in net sales in the aviation segment (where prices are pegged to international parity and to the U.S. dollar) from R$4,233.7 million as of December 31, 2015 to R$3,414.2 million as of December 31, 2016, or 19.4%.

Cost of Sales

	For the Fiscal Year Ended December 31, 2016			For the Fiscal Year Ended December 31, 2015			% Variation
	(in millions of reais, except percentages)
Raízen Energia(1)		(9,967.5	)		(9,148.1	)		9.0	%
Raízen Combustíveis(1)		(64,445.9	)		(58,196.3	)		10.7	%
Cost of Sales		(74,413.4	)		(67,344.4	)		10.5	%

(1) Includes 100% of these entities’ cost of sales which upon the application of IFRS 11 are recorded in the “Equity income of jointly-controlled entity” line item in the consolidated statements of profit or loss and comprehensive income for the fiscal years ended December 31, 2016 and 2015.

Raízen Energia

The cost of sales in the fiscal year ended December 31, 2016 increased 9%, or R$819.4 million, as compared to the fiscal year ended December 31, 2015, due mainly to a 31.6% increase in the price of sugarcane acquired from third parties (primarily from CONSECANA).

Raízen Combustíveis

The cost of sales in the fiscal year ended December 31, 2016 increased 10.7%, or R$6,249.6 million, as compared to the fiscal year ended December 31, 2015. This increase is due to increases in diesel and gasoline prices implemented by Petrobras in September 2015 and a 11% increase in logistics costs as a result of our supply strategy.

Selling Expenses

	For the Fiscal Year Ended December 31, 2016			For the Fiscal Year Ended December 31, 2015			% Variation
	(in millions of reais, except percentages)
Raízen Energia(1)		(732.7	)		(616.9	)		18.8	%
Raízen Combustíveis(1)		(1,303.3	)		(1,188.5	)		9.7	%
Selling expenses		(2,036.0	)		(1,805.4	)		12.8	%

(1) Includes 100% of these entities’ cost of sales, which, upon the application of IFRS 11, are recorded in the “Equity income of jointly-controlled entity” line item in the consolidated statements of profit or loss and comprehensive income for the fiscal years ended December 31, 2016 and 2015.

Raízen Energia

Raízen Energia’s selling expenses increased R$115.8 million, or 18.8%, in the fiscal year ended December 31, 2016 as compared to the fiscal year ended December 31, 2015, due primarily to 25.6% higher expenses with freight. These higher freight expenses can be principally attributed to the higher volume of sales, driven primarily by sales of ethanol to export markets which increased by 2.6%.

74

Raízen Combustíveis

Raízen Combustíveis’ selling expenses increased to R$114.8 million, or 9.7%, in the fiscal year ended December 31, 2016, from R$1,188.5 million in the fiscal year ended December 31, 2015, due primarily to 26.3% increased with freight and logistics expenses reflecting Raízen’s supply strategy.

General and Administrative Expenses

	For the Fiscal Year Ended December 31, 2016			For the Fiscal Year Ended December 31, 2015			% Variation
	(in millions of reais, except percentages)
Raízen Energia(1)		(567.4	)		(518.8	)		9.4	%

Raízen Energia

General and administrative expenses totaled R$567.4 million in the fiscal year ended December 31, 2016, an increase of 9.4% compared to the fiscal year ended December 31, 2015, primarily due to higher personnel expenses and contract labor.

Raízen Combustíveis

General and administrative expenses totaled R$447.8 million in the fiscal year ended December 31, 2016, an increase of 13.5% compared to the fiscal year ended December 31, 2015, primarily due to concentration of marketing expenses and the impact of inflation on general expenses.

Legal and Administrative Proceedings of the Joint Venture

Overview

In the ordinary course of its business, Raízen and its subsidiaries are party to a number of legal proceedings, among which are:

• Corporate Income Taxes and Social Contribution on Net Profits. In December 2011, Raízen Energia received tax assessments, from the Brazilian federal tax authorities seeking to collect corporate income tax and social contributions (specifically, CSLL) with regards to the years 2006 to 2009. The assessments challenged (1) the deductibility of certain amortization expenses and goodwill; (2) the offset of tax losses and the use of a negative calculation basis in connection with CSLL; and (3) certain taxes due in connection with discrepancies in the revaluations of certain assets. As of December 31, 2017, the aggregate amount under discussion was R$444.6 million, including interest and a 150% fine, of which R$231.5 million was classified as having a possible risk of loss and R$213.1 million was classified as having a remote risk of loss. Raízen Energia filed its defense in January 2012. Raízen Energia was notified of the partially favorable decision rendered by the Administrative Court of Tax Appeals to cancel item (3) described above and reduce the fine from 150% to 75%. Raízen Energia filed an appeal to the final level administrative court to discuss the remaining items. Tax authorities also filed an appeal to discuss the fine reduction. Both appeals are waiting for judgment. The alleged underlying facts occurred before the formation of the Raízen joint venture on April 1, 2011. Accordingly, these amounts are subject to reimbursement by shareholders in the event of an adverse decision.

• Goodwill contributed in Raízen Combustíveis. In December 2016 and June 2017 Cosan Lubrificantes received two assessment notices from the Brazilian federal tax authorities seeking to collect corporate income tax and social contributions (specifically, CSLL) arising in connection with the amortization of goodwill on certain investments in the 2011, 2012 and 2013 calculation periods. The first tax assessment notice related to 2011 and 2012 and was in a total amount of R$191.5 million while the second related to 2013 and was in a total amount of R$115.8 million. The risk of loss is estimated as possible with regards to both. This goodwill is the responsibility of Cosan Lubrificantes and was contributed to Raízen Combustíveis.

75

• Social Security Contributions. In June 2010, Raízen Energia filed an ordinary action challenging the obligation to accrue the social security contributions tax based on gross revenue. Currently, the case records are in the Court of Appeals awaiting judgment of the appeal filed by the Brazilian federal government against a favorable first level decision. The risk of loss is classified as probable and as of December 31, 2017, Raízen had recorded provisions in connection with this proceeding in the aggregate amount of R$310.3 million and had judicially deposited the same amount (the two together therefore cancel each other out). The alleged underlying facts occurred both before and after the formation of the Raízen joint venture on April 1, 2011 and, therefore, these amounts are subject to reimbursement by Raízen’s shareholders for a portion of any loss in the event of an adverse decision.

• Industrialized Products Tax. The Brazilian federal government filed a tax enforcement action pursuant to Normative Instruction No. 67/98 with regards to the industrialized products tax allegedly due as a result of the removal of certain types of sugar from Raízen Energia’s facilities from 1995 to 1997 and from 1992 to 1997. As of December 31, 2017, the aggregate amount under discussion was R$393 million. After Raízen Energia filed a motion to stay the tax enforcement action, the first level judge rendered a favorable decision and the Brazilian federal government filed an appeal. The risk of loss is classified as possible. The alleged underlying facts occurred before the formation of the Raízen joint venture on April 1, 2011 and, therefore, these amounts are subject to reimbursement by Raízen’s shareholders. In addition, Raízen is also a party to certain claims regarding the industrial products tax allegedly due on sugar products of certain polarity levels (sugar products with a polarity level of at least 99.5º are not subject to the industrialized products tax).

• PIS and COFINS Credits. The Brazilian federal tax authorities issued tax assessment notices against Raízen Energia related to the allegedly undue use of credits of PIS and COFINS. The notices refer to the credits taken from the costs and expenses with goods and services deemed by the company as inputs for its activities. In relation to the allegedly undue use of PIS and COFINS credits by Raízen Energia before the formation of the Raízen joint venture on April 1, 2011 (and, therefore, subject to reimbursement by our shareholders in case of an adverse decision), Raízen Energia received tax assessment notices which are currently pending a decision of the second administrative trial court and other assessments pending a decision of the lower administrative trial court. As of December 31, 2017, the aggregate amount involved in such proceedings was R$589.9 million. In relation to the allegedly undue use of credits of PIS and COFINS by Raízen Energia and/or Raízen Combustíveis after the formation of the Raízen joint venture on April 1, 2011 (and, therefore, these amounts are subject to reimbursement by Raízen’s shareholders in the event of an adverse decision), Raízen Energia has received tax assessment notices and these tax assessments are currently pending decision of the first administrative trial court. As of December 31, 2017, the aggregate amount involved in these proceedings is R$719.6 million. The risk of loss is classified as possible in each case.

• ICMS – Diesel Oil. The tax authority of the state of São Paulo issued tax assessment notices against Raízen Energia in order to charge ICMS. According to the tax authority, Raízen Energia did not reverse the credit appropriated on the acquisition of diesel oil as feedstock production, due to the output of oil diesel of the establishment in marketing operations. In addition, Raízen Energia allegedly failed to issue tax invoices and also issued tax invoices with mistaken ICMS amounts. In relation to the facts alleged to have occurred before the formation of the Raízen joint venture on April 1, 2011 (Raízen’s shareholders are therefore required to reimburse Raízen for a portion of any loss in case of an adverse decision), Raízen Energia has received tax assessment notices, and with respect to the second instance administrative court issued a decision partially favorable to the company. Raízen Energia is awaiting a decision of the special appeals court. As of December 31, 2017, the amount involved in this proceeding was R$321.6 million. In relation to the facts which allegedly occurred after the formation of the Raízen joint venture on April 1, 2011 (therefore, these amounts are subject to reimbursement by Raízen’s shareholders in the event of an adverse decision), Raízen Energia has received tax assessment notices, which are currently pending decision of the first and second administrative court. As of December 31, 2017, the amount involved in this proceeding was R$482.2 million. The risk of loss is classified as possible in each case.

• PIS and COFINS Offsets (Raízen Combustíveis). The Brazilian federal tax authorities filed a tax assessment to charge PIS and COFINS for the years of 2006 to 2009 in connection with unauthorized offset of tax debts made by Raízen Combustíveis. Raízen Combustíveis obtained a partially favorable decision from the first tier administrative court, and the tax authorities filed an appeal to the second tier administrative court. The amount under dispute as of December 31, 2017 was R$555 million. The risk of loss is classified as possible. The alleged underlying facts occurred before the formation of the Raízen joint venture on April 1, 2011 and, therefore, these amounts are subject to reimbursement by Raízen’s shareholders in the event of an adverse decision.

76

• PIS and COFINS (Raízen Combustíveis). The Brazilian federal tax authorities filed a judicial tax enforcement proceeding in order to charge PIS and COFINS debts originating from refund and offsetting claims made by Raízen Combustíveis. The amount under dispute as of December 31, 2017 was R$468 million and Raízen Combustíveis presented a surety bond in order to continue to litigate. The risk of loss is classified as possible. The alleged underlying facts occurred before the formation of the Raízen joint venture on April 1, 2011 and, therefore, these amounts are subject to reimbursement by Raízen’s shareholders in the event of an adverse decision.

• Labor Civil Public Action No. 0000642-29.5-01.003. Raízen Paraguaçú Ltda. (formerly known as Raízen Tarumã Ltda.), among other defendants, is a party to a civil public action filed by the Labor Prosecutor’s Office of the city of Rio de Janeiro in the state of Rio de Janeiro relating primarily to the following matters: (1) exposure of employees to conditions that are allegedly degrading, (2) alleged irregularities in the outsourcing practices of the companies and (3) alleged noncompliance with health and safety rules and regulations relating to working hours. The risk of loss is classified as possible. Should the proceedings be decided against Raízen, this may result in Raízen being barred from outsourcing certain core activities, an obligation to comply with certain health and safety rules as well as rules applicable to employees’ working hours, the imposition of pecuniary fines in case of noncompliance and indemnification for the violation of employees’ rights in an amount of R$10 million. The alleged underlying facts occurred before the formation of the Raízen joint venture on April 1, 2011 and, therefore, these amounts are subject to reimbursement by Raízen’s shareholders for a portion of any loss in the event of an adverse decision.

Financial Presentation and Accounting Policies

Presentation of Financial Statements

The discussion in this section is based on our audited consolidated financial statements for the fiscal years ended December 31, 2017, 2016 and 2015.

We use IFRS as issued by the IASB for financial reporting purposes. Our audited consolidated financial statements include the financial statements of Cosan Limited and its subsidiaries. Investments in entities in which the Company does not have control but either jointly controls or has significant influence over, are accounted for using the equity method. The results of operations of Raízen Energia and Raízen Combustíveis, our Joint Ventures, are accounted for using the equity method, under IFRS 11, which was adopted by the Company in the nine-month period ended December 31, 2013, and applied retrospectively.

The discussion in this section is also based on a comparison of the fiscal year ended December 31, 2017 with the fiscal year ended December 31, 2016, and a comparison of the fiscal year ended December 31, 2016 with the fiscal year ended December 31, 2015.

Business Segments and Presentation of Segment Financial Data

The Company presents the following reportable segments:

(1)    Raízen Combustíveis: distribution and marketing of fuels, mainly through a franchised network of service stations under the “Shell” brand throughout Brazil;

(2)    Raízen Energia: production and marketing of a variety of products derived from sugar cane, including raw sugar (VHP), anhydrous and hydrated ethanol, and activities related to energy cogeneration from sugarcane bagasse. In addition, this segment holds interests in companies engaged in research and development on new technology;

(3)    Comgás: distribution of piped natural gas under a concession covering part of the State of São Paulo (approximately 180 municipalities, including the São Paulo metropolitan area) to customers in the industrial, residential, commercial, automotive, thermo-generation and cogeneration sectors;

(4)    Cosan Logística: logistics services for transport, storage and port loading of commodities, mainly for sugar products, leasing or lending of locomotives, wagons and other railway equipment;

(5)    Moove, consisting of Cosan Lubrificantes, Stanbridge Group Limited and Comma Oil & Chemicals Ltd.: production and distribution of lubricants under the Mobil brand in Brazil, Bolivia, Uruguay, Paraguay and Europe, as well as in the European and Asian markets under the Comma trademark; and

Reconciliation

(6)    Cosan Corporate: other investments, in addition to the corporate activities of the Company. The other business segments include the subsidiaries responsible for raising funds for the Cosan group.

Following the adoption of IFRS 11, as of April 1, 2013 Cosan no longer proportionally consolidates Raízen Energia and Raízen Combustíveis in its consolidated statement of financial position, consolidated statement of profit or loss and comprehensive income and consolidated cash flows, and the results from these businesses are accounted for under the line item “Equity in income of jointly-controlled entity” in our consolidated statement of profit or loss and other comprehensive income.

Critical Accounting Policies and Estimates

The preparation of the Company’s consolidated financial statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue and expenses at the end of the reporting period. Actual results may differ from these estimates. Such estimates and underlying assumptions are reviewed on an ongoing basis and changes are recognized in the period in which the estimates are revised and in any future periods affected.

78

Summary information about critical judgments, assumptions and estimation uncertainties in applying accounting policies that have the most significant effect on the amounts recognized in the financial statements is included as follows (see note 2.3 of our consolidated financial statements for further information):

Property, plant and equipment and intangible assets, including goodwill. The calculation of depreciation and amortization of intangible assets and property, plant and equipment is based on estimated useful lives. In addition, the determination of the fair value of intangible assets and property, plant and equipment acquired in a business combination or arising from the formation of a Joint Venture is a significant estimate.

The Company performs annually a review of impairment indicators for intangible assets and property, plant and equipment. Also, an impairment test is undertaken for goodwill. Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs to sell and its value in use.

Operating lease commitments. The Company has entered into commercial property leases in relation to its investment property portfolio. The Company has determined, based on an evaluation of the terms and conditions of the arrangements, such as the lease term not constituting a substantial portion of the economic life of the commercial property and the present value of the minimum lease payments not amounting to substantially all of the fair value of the commercial property, that it retains all the significant risks and rewards of ownership of these properties and accounts for the contracts as operating leases.

Income taxes and social contribution. A deferred tax asset is recognized for loss carry forwards to the extent that it is probable that future taxable income will be generated to use such losses. Significant judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the timing and the level of future taxable income together with tax planning strategies.

Other non-current asset. The Company has recognized a receivable in relation to a lawsuit filed against the Federal Government, claiming indemnification due to price controls, which receipt is virtually certain, as the Brazilian Supreme Court passed final judgment and the Federal Government is unable to appeal.

Fair value of derivatives and other financial instruments. When the fair value of financial assets and liabilities recorded in the consolidated financial statements cannot be derived from active markets, their fair value is determined using valuation techniques including the discounted cash flow model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of judgment is required in determining fair values. Judgment is required in the determination of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions on these factors could affect the reported fair value of financial instruments.

Post-employment benefit. The cost of defined benefit pension plans and other post-employment benefits and the present value of the pension obligation is determined using actuarial valuations. An actuarial valuation involves the use of various assumptions which may differ from actual results in the future. These include the determination of the discount rate, future salary increases, mortality rates and future pension increases. A defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed by management at each reporting date.

Share-based payments. Cosan S.A. measures employees’ share-based compensation cost by reference to the fair value of the shares at the grant date. The estimation of fair value for share-based payment transactions requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the plan. This estimate also requires determining the most appropriate inputs to the valuation model including the assumption of the expected life of the stock option, volatility and dividend yield.

Provisions for legal proceedings recognized on business combination transactions. Provisions for legal proceedings resulting from business combinations are estimated at fair value.

Investment in joint ventures. The Company has a 50% interest in a joint agreement. The joint venture agreements require unanimous consent from all parties for all relevant activities.

The two partners have direct rights to the assets of the partnership and are jointly and severally liable for the liabilities incurred by the partnership. This entity is therefore classified as a joint venture and the Company recognizes its interest in the joint venture using the equity method.

79

Recently Issued Accounting Standards

New IASB accounting standards have been published and/or reviewed and may be adopted for the current fiscal year, as described below. Except as described below, there are no other standards and interpretations issued but not yet adopted that may, in management’s opinion, have a significant impact on the results or equity disclosed by the Company.

IFRS 9 Financial Instruments: Classification and Measurement

In July 2016, the IASB issued the final version of IFRS 9 – Financial Instruments which replaces IAS 39 – Financial Instruments: Recognition and Measurement and all previous versions of IAS 39. The new standard brings together the three aspects of the accounting of financial instruments: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for fiscal years beginning on or after January 1, 2018, without prior application permission. With the exception of hedge accounting, retrospective application is necessary, but providing comparative information is not mandatory. For hedge accounting, the requirements are generally applied prospectively, with some limited exceptions.

The Company plans to adopt the new standard on the effective date required and will not restate comparative information. In 2017, the Company conducted a detailed impact assessment of the three aspects of IFRS 9. This evaluation is based on information currently available and may be subject to changes arising from reasonable and bearable information being made available by the Company in 2018, when it adopts IFRS 9. In general, the Company does not foresee any significant impact on the financial statements or shareholders’ equity, except for the effect of applying the impairment requirements of IFRS 9. The Company expects an increase in loss provisions resulting in a negative impact on shareholders’ equity, as discussed below. In addition, the Company will implement changes to the classification of certain financial instruments.

i. Classification and measurement of financial assets

The Company does not expect a significant impact on its balance sheet or equity in applying the classification and measurement requirements of IFRS 9. We expect to continue to measure at fair value all financial assets currently held at fair value. Equity instruments, currently held for sale, with gains and losses recorded in profit or loss, will continue to be measured at fair value through profit or loss.

Loans and receivables are held by the Company to obtain contractual cash flows and should generate cash flows representing only payments of principal and interest. The Company analyzed the contractual cash flow characteristics of these instruments and concluded that they meet the amortized cost criteria in accordance with IFRS 9. Therefore, the reclassification to these instruments will not impact the balance sheet or equity.

The Company has assessed the impacts of gains and losses on financial liabilities attributable to its own risk and has not identified deviations that will result in an accounting for comprehensive income.

ii. Impairment – Financial Assets and Contractual Assets

IFRS 9 requires the Company to record the expected credit losses on all of its debt securities and trade accounts receivable, whether in 12 months or throughout the asset’s life. However, the Company has adopted the more simplified approach and will measure the expected credit losses over a lifetime because the trade accounts receivable and contractual assets do not represent a significant financing component. The provision will be determined by applying the percentage of expected losses on the financial assets to the overdue amounts and overdue loans that may impact the amount of provisioning expense for losses.

The estimated losses were calculated based on the actual experience of credit loss in recent years, and from observing the current conditions and forecasting future economic conditions.

The Company holds investments in debt instruments classified as securities, which are part of investment fund quotas measured at fair value through profit or loss. Therefore, no credit risk analysis of these assets is required.

iii. Hedge accounting

The Company has determined that all existing hedge relationships currently designated as effective hedging relationships will continue to qualify for hedge accounting in accordance with IAS 39. The Company has elected not to retrospectively apply IFRS 9 in the transition to the hedges where the Company excluded the items of progress of the hedge designation in accordance with IAS 39. As IFRS 9 does not change the general principles of how an entity responds to effective hedges, the application of the requirements of hedge of IFRS 9 will not have a significant impact on the Company’s financial statements.

80

iv. Other adjustments

In addition to the adjustments described above, associated with the adoption of IFRS 9, other items in the financial statements, such as deferred taxes, assets held for sale and liabilities associated with them, investments in associates and joint ventures will be adjusted as necessary. Foreign exchange differences in the conversion of foreign operations will also be adjusted.

IFRS 15 Revenue from contracts with customers

IFRS 15 includes as a fundamental principle the recognition of revenue when goods or services are transferred to customers at the transaction price. Revenue is recognized according to this principle by applying a 5-step model:

• Step 1: Identify the contracts with the client;

• Step 2: Identify the performance obligations defined in the contract;

• Step 3: Determine the price of the transaction;

• Step 4: Allocate the price of the transaction to the performance obligations provided for in the agreement; and

• Step 5: Recognize revenue when (or as) the entity meets each performance obligation.

IFRS 15 introduces a comprehensive framework to determine whether and when revenue is recognized, and how much revenue is received. IFRS 15 replaces current revenue recognition standards.

The Company recognizes revenues from the following main sources:

i. Sale of products

The Company recognizes sales revenues upon delivery to the customer. Delivery is considered to be the moment when the customer accepts the goods, and the risks and benefits related to the property are transferred. Revenue is recognized at this time as long as revenue and costs can be measured reliably, receipt of the consideration is probable and there is no continuous involvement of management with the products.

In accordance with IFRS 15, revenue must be recognized when the customer obtains control of the products. For contracts with customers where the sale is generally expected to be the only execution obligation, the adoption of IFRS 15 should have no impact on revenue and results. The Company expects revenue recognition to occur at a time when control of the good is transferred to the customer, usually at the time of delivery of the goods.

The Company operates in the production and distribution of lubricants including the brands Mobil and Comma, as well as the production and distribution of biomass pellets. Products are sold in contracts identified with individual customers and in sets, as a package of goods or services.

Some lubricant sales contracts cannot be purchased separately from a package of services. However, the goods and services are clearly distinct in the contracts. This sales modality represents two separate performance obligations and therefore revenue will be recognized for each of these performance obligations when control of the respective goods and services is transferred to the customer. Although IFRS 15 requires that the transaction price be allocated to different performance obligations based on the independent selling price, Management does not expect the allocation of revenues from the sale of lubricants and services rendered to be significantly different from that currently practiced, in which revenues are identified, measured and recorded separately.

ii. Services provided

The Company provides gas distribution services through the subsidiary Comgás and logistics services through the subsidiary Cosan Logística. Based on the Company’s assessment, the fair value and selling prices of individual services are broadly similar. Therefore, the Company does not expect the application of IFRS 15 to result in significant differences in the recognition of revenue for these services.

81

iii. Other effects

a) Incremental cost to obtain contracts

The Company has identified certain lubricant sales agreements that contain commission clauses that are under evaluation. These clauses are included as incremental costs associated with contract acquisition and are expressly chargeable to the customer. In the Company’s evaluation, when IFRS 15 is adopted, certain contracts may be recognized as assets due to the incremental cost of obtaining a customer agreement. These will be amortized on a systematic basis consistent with the transfer of the goods or services to the customers. On December 31, 2017, the amount of R$39,275 related to sales commissions was recognized.

The Company was presenting expenses related to contracts as sales expenses.

b) Disposal of non-financial assets

The recognition and measurement requirements in IFRS 15 also apply to the recognition and measurement of any gains or losses on the disposal of nonfinancial assets (such as property, plant and equipment and intangible assets), when such disposal does not occur in the normal course of business. However, there is no expectation that the effect of these changes will be material to the Company.

iv. Presentation and disclosure requirements

The presentation and disclosure requirements in IFRS 15 are more detailed than those contained in the current IFRS. The presentation requirements represent a significant change from the current practice and significantly increase the volume of disclosures required of the Company’s financial statements. Many of the disclosure requirements of IFRS 15 are new and the Company has assessed that the impact of some of them will be significant. In particular, the Company expects the explanatory notes to the financial statements to require expansion due to the disclosure of significant judgments made. These include determining the timing of the transaction price of contracts that include variable consideration, as the transaction price has been attached to the performance obligation and the assumptions used to estimate the individual selling prices of each performance obligation. In addition, as required by IFRS 15, the Company will disaggregate the recognized revenues from contracts that include the sale of both goods and services. In 2017, the Company continued to test the internal controls, policies and procedures required to collect and disclose the information required.

v. Transition

The Company plans to adopt IFRS 15 using the cumulative effect method, with initial application of the standard at the initial date (January 1, 2018). As a result, the Company will not apply the requirements of IFRS 15 to the comparative period presented.

The Company plans to use the practical expedients for concluded contracts. This means completed contracts that have commenced and ended in the same comparative presentation period, as well as contracts that concluded at the beginning of the earliest period presented, will not be restated.

IFRS 16 Leases

IFRS 16 introduces a single model for the accounting of leases in the balance sheet for tenants. A lessee recognizes a right of use asset that represents his right to use the leased asset and a lease liability that represents his obligation to make lease payments. Optional exemptions are available for short-term leases and low value items. The lessor’s accounting remains similar to the current standard, that is, lessors continue to classify leases as financial or operating.

IFRS 16 replaces existing lease standards, including IAS 17 Leasing Operations and IFRIC 4, SIC 15 and SIC 27 Complementary Aspects of Leasing Operations.

The standard is effective for annual periods beginning on or after January 1, 2019. Early adoption is permitted only for financial statements in accordance with IFRSs and only for entities that apply IFRS 15 Revenue from Contracts with Customers or before the date of initial application of IFRS 16.

The Company began an initial assessment of the potential impact on its financial statements. So far, the most significant impact identified is that the subsidiary Rumo will recognize new assets and liabilities for its operating leases. In the jointly owned subsidiary Raízen, it is expected to have significant impacts on land leases. In addition, the nature of the expenses related to these leases will be changed, since IFRS 16 replaces the line operating lease expense due to depreciation of the right of use and interest on the lease liabilities. The Company has not yet decided whether to use the optional exemptions.

82

As a lessee, the Company may apply the standard using a:

• Retrospective approach; or

• Modified retrospective approach with optional practical expedients.

The lessee will apply this choice consistently to all of its leases. The Company should apply IFRS 16 initially on January 1, 2019. The Company has not yet determined which transition approach to apply.

The Company has not yet quantified the impact of adopting IFRS 16 on its assets and liabilities. The quantitative effect of the adoption of IFRS 16 will depend specifically on the transition method chosen, the use of practical expedients and recognition exemptions, and any additional leases that the Company will enter into. The Company expects to disclose its transition approach and quantitative information prior to adoption.

IFRIC 22 — Foreign Currency Transactions and Advance Consideration

IFRIC states that the date of the transaction for the purpose of determining the exchange rate should be the date on which the entity initially recognizes the nonmonetary asset or liability arising from the payment or early receipt.

This interpretation takes effect for annual periods beginning on or after January 1, 2018. The initial adoption is permitted retrospectively, or prospectively.

Management conducted the analysis of the impacts of the initial adoption of IFRIC 22 and considered them to be immaterial. Thus, whether the adoption will be carried out prospectively or retrospectively is still being determined.

There are no other IFRS standards or IFRIC interpretations that have not come into effect and that are expected to have a material impact on the Company.

Principal Factors Affecting Our Results of Operations

In addition to the factors that are described in “Item 4. Information on the Company—B. Business Overview,” our results of operations have been influenced and will continue to be influenced by the following key factors:

Brazilian Economic Environment

The Brazilian economic environment has historically been characterized by significant variations in economic growth, inflation and currency exchange rates. Our results of operations and financial condition are influenced by these factors and the effect that these factors have on employment rates, the availability of credit and average wages in Brazil. The following table sets forth Brazilian inflation rates, interest rates, and exchange rates for the periods indicated:

	For the Fiscal Year Ended December 31,
	2017		2016		2015
GDP growth		1.0%		(3.6)%		(3.8)%
Inflation (IGP-M)		(0.5)%		7.2%		10.5%
Inflation (IPCA)(1)		3.0%		6.3%		10.7%
Interbank rate – CDI (average)(2)		7.0%		14.0%		13.2%
Long-term interest rates (average)(3)		7.0%		7.5%		6.3%
Exchange rate at the end of the period per U.S.$1.00		R$3.31		R$3.26		R$3.90
Average exchange rate per U.S.$1.00		R$3.19		R$3.51		R$3.33
Appreciation (depreciation) of the real against the U.S. dollar (4)		(1.5)%		16.5%		(47.0)%

Sources: IBGE, Brazilian Central Bank, CETIP S.A. – Mercados Organizados and FGV.

(1) IPCA is a consumer price index calculated by IBGE.

(2) CDI refers to the average overnight interbank loan rates in Brazil.

(3) The Brazilian long-term interest rate (taxa de juros de longo prazo), or TJLP, is the rate applicable to long-term loans by BNDES.

(4) Comparing the PTAX exchange rate (the rate calculated by the Brazilian Central Bank) at the end of the period’s last day with the day immediately prior to the first day of the period discussed, PTAX is the exchange rate calculated at the end of each day by the Brazilian Central Bank. It is the average rate of all business conducted in U.S. dollars on the determined date in the interbank exchange market.

83

General economic stability in Brazil following the onset of the global financial crisis in 2009 allowed the Brazilian Central Bank to continue its policy of reducing interest rates. Due to inflation and other general macroeconomics concerns, the Brazilian Central Bank began increasing interest rates, with the SELIC, a benchmark interest rate, reaching 10.00% at the end of December 31, 2013, 11.75% at the end of December 31, 2014 and 14.25% at the end of December 31, 2015. The Brazilian Central Bank has been reducing interest rates since then, with the SELIC reaching 13.75% as of December 31, 2016 and 7.00% as of December 31, 2017.

The recent economic instability in Brazil caused by, among other things, the rise of inflation, a slowdown in GDP growth, and uncertainty as to whether the Brazilian government will enact the necessary economic reforms to improve Brazil’s deteriorating fiscal accounts and economy have led to a decline in market confidence in the Brazilian economy and a government crisis. On May 12, 2016, the Brazilian Senate voted to begin its review of the impeachment proceedings against former President Dilma Rousseff, who was suspended from office. After the legal and administrative process for the impeachment, Brazil’s Senate removed the former president from office on August 31, 2016 for infringing budgetary laws. Michel Temer, the former vice president, who has served as president of Brazil since Ms. Rousseff’s suspension in May, was sworn in by Senate to serve out the remainder of the presidential term until 2018. There was an ongoing proceeding before the Brazilian Higher Electoral Court (Tribunal Superior Eleitoral) alleging that the electoral alliance between Ms. Rousseff and Mr. Temer in the 2014 general election had violated campaign finance laws. On June 9, 2017, the Brazilian Higher Electoral Court absolved the electoral alliance, including President Temer of wrongdoing; however, he remains subject to heightened scrutiny due to the ongoing Lava Jato investigations. The resolution of the political and economic crisis in Brazil still depends on the approval of reforms that are expected to be promoted by the new president. We cannot predict which policies Mr. Temer may adopt or change during his presidency or the effect that any such policies might have on our business and on the Brazilian economy. Any such new policies or changes to current policies may have a material adverse effect on our business, results of operations and financial condition.

Presidential elections are to be held in Brazil in the second half of 2018. We cannot predict the outcome of those elections, including whether any successor to Mr. Temer will adopt policies or changes to current policies which may have a material adverse effect on us. Furthermore, the political uncertainty resulting from the presidential elections may have an adverse effect on our business, results of operations and financial condition.

Any deterioration in Brazil’s rate of economic growth, changes in interest rates, the unemployment rate or price levels generally may limit the availability of credit, income and purchasing power of our customers, thereby adversely affecting demand for our products.

Acquisitions, Partnerships and Corporate Restructurings

Our strategy is to be a leading Brazilian group in the energy and infrastructure businesses. For this reason, since May 2004, we have expanded our operations primarily through acquisitions, partnerships and corporate restructurings. We have also diversified into other operations to become a vertically integrated energy and infrastructure company. As a result, our net sales and gross profit have increased significantly.

Sugar

The profitability of our sugar products is mainly affected by fluctuations in the international price of raw sugar and in the real/dollar exchange rate. International raw sugar prices are determined based on the New York Board of Trade Futures Contract No. 11, or “NY11.” Refined sugar trades at a premium to raw sugar, known as the “white premium,” and its price is determined based on the London International Financial Futures and Options Exchange Contract No. 5, or “LIFFE No. 5.” Prices are affected by the perceived and actual supply and demand for sugar and its substitute products. The supply of sugar is affected by weather conditions, governmental trade policies and regulations and the amount of sugarcane and sugar beet planted by farmers, including substitution by farmers of other agricultural commodities for sugarcane or sugar beet. Demand is affected by growth in worldwide consumption of sugar and the prices of substitute sugar products. From time to time, imbalances may occur between overall sugarcane and sugar beet processing capacity, sugarcane and sugar beet supply and the demand for sugar products. Prices of sugar products are also affected by these imbalances, which, in turn, impact our decisions regarding whether and when to purchase, store or process sugarcane and whether to produce sugar or more ethanol.

Ethanol

Our ethanol products are affected by domestic Brazilian and international prices of ethanol, competition, governmental policies and regulations and market demand for ethanol as an alternative or additive to gasoline. The price for ethanol we sell in Brazil is set in accordance with market prices, using indices published by the Agriculture School of the University of São Paulo (Escola Superior de Agricultura Luiz de Queiroz—ESALQ) and B3 as a reference. Prices for ethanol we export are set based on international market prices, including the New York Board of Trade’s recently launched ethanol futures contract. Prices for the industrial alcohol and bottled alcohol products we sell are also set based on market prices and have been historically higher than market prices for ethanol.

The table below sets forth the prices for hydrous ethanol in the Brazilian market for the periods indicated:

Demand for Fuels

Demand for gasoline, ethanol and diesel is susceptible to volatility related to the level of economic activity in Brazil and may also fluctuate depending on the performance of specific industries in the Brazilian market. We expect that a decrease in economic activity would adversely affect demand for fuels.

Currency Fluctuations

A significant proportion of the sales of sugar of Raízen Energia, a significant proportion of natural gas purchase of Comgás, and a significant proportion of the base oil purchases of Cosan Lubrificantes are conducted in U.S. dollars. Therefore, a depreciation of the real against the U.S. dollar would have the effect of increasing our sales in Raízen Energia, and increasing our costs of sales in Comgás and Moove. An appreciation of the real against the U.S. dollar would have the opposite effect.

A significant proportion of our debt is denominated in U.S. dollars. A depreciation of the real against the U.S. dollar would increase our debt burden and our related financial expenses. However, we have receivables and other financial assets denominated in U.S. dollars, which would partially offset the impact that a depreciation of the real would have on our financial position. An appreciation of the real against the U.S. dollar would have the opposite effect.

See also “—Hedging Transactions and Exposures.”

Seasonality

Our business is subject to a degree of seasonality as described below. See also “Item 3. Key Information—D. Risk Factors—Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate—Our business is subject to seasonal trends based on the sugarcane growing cycle in the Central-South region of Brazil.”

Raízen

Raízen’s sugar production depends on the volume and sucrose content of the sugarcane that it cultivates or that is supplied to it by growers located in the vicinity of Raízen’s mills. Crop yields and sucrose content depend primarily on weather conditions such as rainfall and temperature, which vary and may be influenced by global climate change. Weather conditions have historically caused volatility in the ethanol and sugar industries and, consequently, in our results of operations by causing crop failures or reduced harvests. Flood or drought, which may be influenced by global climate change, can adversely affect the supply and pricing of the agricultural commodities that we sell and use in our business. During the third and fourth quarter of 2014, a severe drought affected the areas in which Raízen operates.

Future weather patterns may reduce the amount of sugar or sugarcane that Raízen can recover in a given harvest or its sucrose content. In addition, the business of Raízen Energia in particular is subject to seasonal trends based on the sugarcane growing and harvesting cycle in the Central-South region of Brazil. The annual sugarcane harvesting period in the Central-South region of Brazil usually begins in April or May and ends in November or December. This creates fluctuations in our inventory, usually peaking in December to cover sales between crop harvests (i.e., December through April), and a degree of seasonality in our gross profit, with ethanol and sugar sales significantly lower in the quarter ended on December 31.

Cosan Logística

Rumo is subject to the seasonality that influences the sugarcane and grain harvest. During the peak months of the harvests, there is higher demand for transport and logistics operations.

Inflation

Inflation rates in Brazil were 5.8% in 2012, 5.9% in 2013, 6.4% in 2014, 10.7% in 2015, 6.3% in 2016 and 3% in 2017, as measured by the Extended National Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplio), or “IPCA,” published by the Brazilian Institute for Geography and Statistics (Instituto Brasileiro de Geografia e Estatística), or “IBGE.” In 2016, the inflation rate reached a level of 4.3% for the twelve-month period ending March 31, 2017.

86

Inflation affects our financial performance by increasing certain of our operating expenses denominated in reais (and not linked to the U.S. dollar). These operating expenses include labor costs, leases, and selling and general administrative expenses. However, inflation did not have a material impact on our business for the periods presented.

See also “Item 3. Key Information—D. Risk Factors—Risks Related to Brazil—Inflation and government measures to curb inflation may adversely affect the Brazilian economy, the Brazilian securities market, our business and operations and the market prices of our shares.”

Cost Structure

Our cost structure for Raízen Energia may be divided into costs that are linked to the prices of our products and costs that are not linked to the prices of our products. Two of our principal cost components, raw materials and land leases, are linked to the prices of our products. Accordingly, we adjust the prices of our products to follow fluctuations in the cost of our raw materials and leased land, substantially minimizing the impact of this cost volatility on our results of operations. In addition, another relevant portion of our costs is represented by agricultural and industrial inputs, some of which are imported and which are also subject to price fluctuations primarily as a result of exchange rate variations. As 5% of our net sales are derived from exports, a portion of fluctuations in the costs of these inputs is offset by similar fluctuations in our Brazilian and international prices, minimizing the impact of this cost volatility on our results of operations.

Our cost structure for Comgás is affected by fixed and variable costs. Costs related to our property, plant and equipment incur fixed depreciation charges which increase in line with our capital expenditure. Costs relating to the natural gas resource, costs relating to transportation and other gas services are affected by volumes sold.

Our cost structure for Lubricants is affected by the cost of imported base oil and additives for lubricants blending.

Our cost structure for Cosan Logística is affected by fixed and variable costs. Costs related to our property, plant and equipment incur fixed depreciation charges, which increase in line with our capital expenditure. Costs relating to the transportation of sugar and other commodities are partially dependent on sales volumes.

Other Factors

Other factors that will impact the results of our operations include:

• hedging transactions (as discussed under “—Hedging Transactions and Exposures”);

• trade barriers in U.S., European and other markets that currently limit access to their domestic sugar industry through quotas, subsidies and restrictions on imports;

• the evolving use of ethanol derivatives as an alternative to oil derivatives and as a cleaner burning fuel, derived from renewable sources;

• the use of ethanol as a cleaner burning fuel, derived from renewable sources;

• changes in international prices of oil (denominated in U.S. dollars) and related changes in the domestic prices of oil (denominated in reais);

• the growth rate of the global economy and its resulting corresponding growth in worldwide sugar consumption; and

• the tax policies adopted by the Brazilian government and the governments of the Brazilian states in which we operate (including tax incentives from which we benefit), and our resulting tax obligation.

Hedging Transactions and Exposures

Our management has overall responsibility for the establishment and oversight of our risk management framework. Our board of directors has established the risk management committee, which is responsible for developing and monitoring our risk management policies. The committee reports regularly to our board of directors on its activities.

87

Our risk management policies are established to identify and analyze the risks that we face, to set appropriate risk limits and controls and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and our activities. Our management, through its training, standards and procedures, aims to maintain a disciplined and constructive control environment in which all employees understand their roles and obligations.

Our hedging strategy primarily seeks to protect our cash flows from risks arising from exchange rates fluctuations. Accordingly, certain of our derivative financial instruments have been designated for hedge accounting, namely: (1) at Cosan S.A., the Senior Notes due 2023 and the associated derivative financial instruments; (2) at Comgás, the third and fifth issuances of debentures due in 2020 and 2023, respectively, and the associated derivative financial instruments; and (3) at Rumo, the Senior Notes due 2024 and the associated derivative financial instruments.

In addition, our joint venture Raízen Energia hedges part of the future price risk of its sugar production, estimated to be exported and exchange rate derivative transactions, using future contracts, options and swaps. Its hedging strategy seeks to protect it from cash flow risks caused by commodities price and exchange rates fluctuations and as most of the derivative instruments have been designated for hedge accounting, Raízen Energia has not experienced material gains or losses in its financial results.

Net Sales

We report net sales after deducting Brazilian federal and state taxes assessed on gross sales (ICMS, PIS, COFINS), IPI (a federal value-added tax assessed on our gross sales in the Brazilian market at rates that vary by product) and INSS (federal social contribution taxes assessed on our gross sales in the Brazilian market of our agribusiness entities at a rate of 2.85%). Deductions from gross sales in the Brazilian domestic market, which are subject to these taxes, are significantly higher than our deductions from gross sales in export markets.

The change in the various components consists of the following:

Cosan Logística

Sales increased from R$5,014.6 million in the fiscal year ended December 31, 2016 to R$5,946.3 million in the fiscal year ended December 31, 2017, mainly due to an increase in volume transported of 23% compared to the fiscal year ended December 31, 2016. Net sales from Northern Operations totaled R$4,439.7 million in the fiscal year ended December 31, 2017, compared with R$3,651.5 million in the fiscal year ended December 31, 2016, primarily due to an increase in corn volume transported to meet the higher demand from a record grain crop that shipped at the year’s end. In addition, capacity gains also allowed for higher soybean meal volumes. The Southern Operations generated net revenue of R$1,283.1 million from services, an increase of 16.89% compared to the fiscal year ended December 31, 2016, due to higher pulp transportation levels and an increase in grain transportation. The decrease of 15.79% in Container Operations compared to the fiscal year ended December 31, 2016 reflected the Company’s strategy of diversifying cargo and rationalizing non-profitable routes, especially in the Rio Grande do Sul and Mercosur corridors, in addition to lower demand for refrigerated-product transportation.

Comgás

Comgás’ revenues in the fiscal year ended December 31, 2017 amounted to R$5,537.9 million, representing the results of its activities of natural gas trading and distribution in the concession region of the state of São Paulo. This represented a decrease of 2.11% as compared to the fiscal year ended December 31, 2016, due to decreases in the average sales price authorized by ARSESP in May and September 2016, combined with a 0.7% decrease in volume distributed, which were partially offset by tariff increases in May 2017.

Moove

Our lubricants businesses comprise our lubricants and specialties business and certain other operations. The net revenue of the lubricants business was R$2,129.5 million in the fiscal year ended December 31, 2017, an increase of 13.05% compared to the fiscal year ended December 31, 2016, due to a 6% increase in the sales volume and a better mix of products sold.

Our total cost of sales and services increased by 11% to R$9,232.2 million during the fiscal year ended December 31, 2017, from R$8,317.5 million during the fiscal year ended December 31, 2016 due to the factors described below.

Cosan Logística

The cost of Cosan Logística’s services provided in the fiscal year ended December 31, 2017 increased 11.99%, to R$4,221 million, as compared to R$3,769.1 million the fiscal year ended December 31, 2016. This increase was primarily due to a 23% increase in volume transported. There was also a 10% increase in the average price of diesel, the effect of which were partially offset by the greater efficiency of certain new locomotives, which resulted in an overall 12% decrease in fuel consumption. Additionally, we undertook a review of the useful lives of certain property, plant and equipment. Similarly, higher grain volumes in the North Operation contributed to higher logistic costs. Fixed costs remained in line with the previous years, reflecting the strategy of operational leverage and cost dilution, according to the Company’s business plan. The recognition of tax credits contributed to a decrease in other operating expenses, while costs associated with depreciation and amortization increased due to the capitalization of investments made in 2016.

Comgás

Comgás’ costs of sales and services, which corresponds to the cost of gas, transportation and construction activity on the gas distribution infrastructure under concession, totaled R$3,492.4 million in the fiscal year ended December 31, 2017. This represented an increase of 10.03% as compared to the fiscal year ended December 31, 2016, mainly due to an increase of 16% in the unitary cost of natural gas. The increase in the unitary cost of gas was mainly due to the change in the price of oil, which is the reference for gas supply agreements.

Moove

The cost of lubricants sales totaled R$1,545.7 million in the fiscal year ended December 31, 2017, an increase of 10.50% as compared to the fiscal year ended December 31, 2016, mainly due to a 5.8% increase in lubricant sales volume.

Selling Expenses

Selling expenses are primarily related to transportation costs, including freight costs and shipping costs for lubricant sold in Brazil and exported, as well as storage and loading expenses of ethanol and sugar for export at our and third parties’ port facilities. Moove’s lubricant marketing expenses, as well as storage expenses, are also included as selling expenses.

Selling expenses decreased by 2.64% to R$652.9 million during the fiscal year ended December 31, 2017, from R$670.6 million during the fiscal year ended December 31, 2016, primarily as a result of certain cost-cutting measures undertaken with regards to personnel as well as lower depreciation, the effects of which were partially offset by the effects of inflation (at a rate of 3% per year as measured by the IPCA) on our selling expenses.

Moove

Selling expenses increased 6.82%, to R$386.7 million, in the fiscal year ended December 31, 2017, as compared to R$362.0 million in the fiscal year ended December 31, 2016.

Cosan Logística

General and administrative expenses totaled R$285.4 million in the fiscal year ended December 31, 2017, a decrease of 16.79% compared to the fiscal year ended December 31, 2016, primarily as a result of a decrease in insurance-related expenses and a 10.6% decrease in personnel expenses.

Comgás

General and administrative expenses totaled R$345 million in the fiscal year ended December 31, 2017, compared with R$332.3 million in the fiscal year ended December 31, 2016. The increase is mainly explained by increase of 8% in expenses relating to services provided by third parties and a 154% increase in maintenance expenses.

Moove

General and administrative expenses totaled R$94 million in the fiscal year ended December 31, 2017, an increase of 29.48% when compared to the fiscal year ended December 31, 2016, primarily due to a 48% increase in employee benefit expenses, reflecting an increase in variable compensation as a result of improvements in certain operational indicators, as well as a 137.2% increase in third-party service expenses.

Cosan Corporate

General and administrative expenses totaled R$210.9 million in the fiscal year ended December 31, 2017, a decrease of 16.57% when compared to the fiscal year ended December 31, 2016, primarily due to the Company’s efforts to control and reduce costs incurred in connection with third parties, services and wages and benefits, which partially offset the impact of inflation on general expenses.

Other income (expense), net

Other income, net increased from R$116.3 million in the fiscal year ended December 31, 2016 to R$877.6 million in the fiscal year ended December 31, 2017. This was mainly due to gains related to the assignment of credit rights in the amount of R$1,034 million deriving from certain indemnity lawsuits filed against the federal government.

Interest in earnings of associates

Equity in earnings of associates includes our 3% interest in Radar, 51% interest in Tellus Brasil, 50% interest in Novvi Limited, 51% interest in Janus Brasil, 50% interest in Vertical and other investments. Equity in earnings of associates increased to R$17.2 million in the fiscal year ended December 31, 2017 from negative R$4.4 million in the fiscal year ended December 31, 2016, mainly due to better business performance.

Equity in earnings of joint ventures

Equity in earnings of joint ventures includes our 50% interests in Raízen Energia and Raízen Combustíveis. Equity income decreased to R$985.1 million in the fiscal year ended December 31, 2017 from R$1,570.1 million in the fiscal year ended December 31, 2016. This was a result of the factors detailed above for Raízen Energia and Raízen Combustíveis. These factors are not consolidated into our financial statements but accounted for in equity, in accordance with IFRS 11.

Financial results, net

Financial results, net in the fiscal year ended December 31, 2017 totaled a net financial expense of R$2,751.5 million compared with a net financial expense of R$3,055.8 million in the fiscal year ended December 31, 2016, a decrease of R$304.3 million, or 10%. This was mainly due to cost of debt pegged to the CDI rate, which decreased from 13.63% p.a. in December 31, 2016 to 6.89% p.a. in December 31, 2017.

Cost of gross debt. The total cost of gross debt (which includes interest expenses, exchange variation and derivative gain or loss) decreased by R$255 million, or 10.31%. This was mainly due to the lower cost of debt indexed to the CDI rate. However, the increase in Cosan’s gross debt is due to the issuance of U.S.$500 million in Senior Notes due 2024, the proceeds of which were used to increase Rumo’s capital and liability management at the holding level, and also the issuance of U.S.$750 million in Senior Notes due 2024 by Rumo Logística, the proceeds of which were used for liability management.

Interest income. Interest income grew R$43.9 million, due to the higher average cash balance associated primarily with Rumo’s R$2,640 million capital increase.

Other charges and monetary variations. Other charges and monetary variations decreased 0.48% to R$1,112.8 million. Banking expenses, fees and other expenses increased by R$41.2 million.

Income tax (expense) benefit

Income tax expenses amounted to R$428.4 million for the fiscal year ended December 31, 2017, compared to R$61.7 million in the fiscal year ended December 31, 2016. This increase was a consequence of the higher profit in the fiscal year ended December 31, 2017 as compared to the fiscal year ended December 31, 2016, mainly due to a R$788 million gain from an assignment of credit rights arising from certain indemnification actions proposed against the Brazilian federal government. In the fiscal year ended December 31, 2017, the effective tax rate was 29.05%, which was slightly lower than the nominal corporate tax rate of 34%, mainly due to interest in earnings of investees of R$340.8 million and tax incentives of R$74.4 million, which were partially offset by differences in tax rates on losses of overseas companies of R$89.1 million, interest on shareholders’ equity of R$21.4 million, non-deductible expenses of R$52.2 million and unrecognized tax losses of R$177.8 million.

Net income attributable to owners of the Parent

As a result of the foregoing, net income attributable to our owners was R$551 million in the fiscal year ended December 31, 2017, compared to R$277.8 million in the fiscal year ended December 31, 2015. This represented an increase of 98.34% after deducting net income attributable to non-controlling interests of R$495.3 million and R$181.2 million in the fiscal year ended December 31, 2017 and the fiscal year ended December 31, 2016, respectively.

Net Sales

We report net sales after deducting Brazilian federal and state taxes assessed on gross sales (ICMS, PIS, COFINS), IPI (a federal value-added tax assessed on our gross sales in the Brazilian market at rates that vary by product) and INSS (federal social contribution taxes assessed on our gross sales in the Brazilian market of our agribusiness entities at a rate of 2.85%). Deductions from gross sales in the Brazilian domestic market, which are subject to these taxes, are significantly lower than our deductions from gross sales in export markets.

Cosan Logística

Sales in the fiscal year ended December 31, 2016 increased from R$4,037.9 million in the fiscal year ended December 31, 2015 to R$5,014.6 million in the fiscal year ended December 31, 2016, primarily due to the increase in the volume of Rumo’s operations as a result of the ALL Acquisition. In addition, Rumo’s port terminal loading volume increased in the fiscal year ended December 31, 2016 in comparison to 2015, with net sales from services from port terminal loading increasing 29.1% to R$308.6 million in the fiscal year ended December 31, 2016, compared to R$239.1 million in the fiscal year ended December 31, 2015. Net sales from transportation services totaled R$4,623.1 million in the fiscal year ended December 31, 2016, compared to R$3,572.5 million in the fiscal year ended December 31, 2015, primarily due to the ALL Acquisition and the addition of railway services in 2015. Finally, net revenue from services from other operations totaled R$82.8 million in the fiscal year ended December 31, 2016, compared to R$226.3 million in the fiscal year ended December 31, 2015, primarily due to the ALL Acquisition and related right-of-way rights charged to other rail transport operators.

Comgás

Comgás’ revenues in the fiscal year ended December 31, 2016 amounted to R$5,657.1 million, representing the results of its activities of distribution and trading of natural gas in the concession region of the state of São Paulo. This was a decrease of 14.25% as compared to the fiscal year ended December 31, 2015, due to a decrease of the average sales price, authorized by ARSESP during 2016.

Moove

Our lubricants businesses comprise our lubricants and specialties business and certain other operations. The net revenue of the lubricants business was R$1,883.7 million in the fiscal year ended December 31, 2016, an increase of 7.54% compared to the fiscal year ended December 31, 2015, due to foreign exchange gains arising as a result of the appreciation of the real against major international currencies such as the U.S. dollar during 2016.

Our total cost of sales and services decreased by 3.80% to R$8,317.5 million during the fiscal year ended December 31, 2016, from R$8,645.7 million during the fiscal year ended December 31, 2015 due to the factors described below.

Cosan Logística

The cost of Cosan Logística’s services provided in the fiscal year ended December 31, 2016 increased 35.98%, to R$3,769.1 million, as compared to the fiscal year ended December 31, 2015, primarily due to an increase in depreciation and amortization expenses. This increase in depreciation and amortization expenses resulted from the total of R$3,104.7 million in capital investments made by Rumo over the last two years in the North and South operations reflecting higher investments in capacity expansion, such as: (i) the acquisition of locomotives and rail cars; (ii) the project for improvements in the rails of the Port of Santos region; (iii) revitalization of stretches; and (iv) renovations, improvements and recovery of some rail yards and the main terminals operated by the company, in order to increase productivity.

Comgás

Comgás’ costs of sales and services, which corresponds to the cost of gas, transportation and construction activity on the gas distribution infrastructure under concession, totaled R$3,174.1 million in the fiscal year ended December 31, 2016, a decrease of 30.7% as compared to the fiscal year ended December 31, 2015, due to a decrease in the cost of natural gas and movements in foreign exchange rates.

Moove

The cost of lubricants sales totaled R$1,398.8 million in the fiscal year ended December 31, 2016, an increase of 5.79% as compared to the fiscal year ended December 31, 2015, mainly due to an increase in the sales volumes of lubricants of 4%, and to adverse movements in foreign exchange rates, which decreased the cost of importing base oil.

Selling Expenses

Selling expenses are primarily related to transportation costs, including freight and shipping costs for ethanol, sugar, fuel and lubricant sold in Brazil and exported, as well as storage and loading expenses of ethanol and sugar for export at our and third parties’ port facilities. The major portion of our sales of ethanol in Brazil is sold at the mill to distribution companies, and therefore there are no shipping costs. Moove’s lubricant marketing expenses, as well as fuel storage expenses, are also included as selling expenses.

Cosan Logística

Cosan Logística’s selling expenses increased to R$4.6 million in the fiscal year ended December 31, 2016 as compared to the fiscal year ended December 31, 2015, due primarily to the consolidation of ALL’s full year 2016 operations and higher volume operations resulting from the segment operations.

Selling expenses increased by 6.87% to R$670.6 million during the fiscal year ended December 31, 2016, from R$627.5 million during the fiscal year ended December 31, 2015. This change was primarily due to higher depreciation and amortization expenses in the fiscal year ended December 31, 2016 compared to the fiscal year ended December 31, 2015, mainly due to additions to property, plant and equipment in 2015 in a total aggregate amount of R$521.2 million.

Selling expenses increased 24.14% in the fiscal year ended December 31, 2016, to R$362.0 million, as compared to R$291.6 million in the fiscal year ended December 31, 2015, mainly due to R$72.7 million in commission expenses relating to sales contracts with customers.

Our total general and administrative expenses increased by 9.76% to R$1,000.7 million during the fiscal year ended December 31, 2016 from R$911.7 million during the fiscal year ended December 31, 2015, due to the factors described below.

98

Cosan Logística

General and administrative expenses totaled R$343.0 million in the fiscal year ended December 31, 2016, an increase of 10.18% compared to the fiscal year ended December 31, 2015 as a result of the ALL Acquisition which was completed on April 1, 2015, and a related increase in administrative functions and costs related thereto.

Comgás

General and administrative expenses totaled R$332.3 million in the fiscal year ended December 31, 2016, compared with R$332.8 million in the fiscal year ended December 31, 2015. The decrease is mainly explained by inflation in the period, which was partially offset by improved control of expenses.

Moove

General and administrative expenses totaled R$72.6 million in the fiscal year ended December 31, 2016, a decrease of 6.56% when compared to the fiscal year ended December 31, 2015, primarily due to concentration of marketing expenses in this period and the impact of inflation on general expenses.

Cosan Corporate

General and administrative expenses totaled R$252.8 million in the fiscal year ended December 31, 2016, an increase of 33.12% when compared to the fiscal year ended December 31, 2015, primarily due to officers’ and directors’ compensation and the impact of inflation on general expenses.

Other income (expense), net

Other income, net comprises other income and expenses. Other income, net decreased from an income of R$252.3 million in the fiscal year ended December 31, 2015 to an expense of R$116.3 million in the fiscal year ended December 31, 2016, primarily due to gains on compensation claims recorded in 2015 in the amount R$345.2 million and effect of legal proceedings, recoverable and tax installments.

Interest in earnings of associates

Equity in earnings of associates includes our 3% interest in Radar, 51% interest in Tellus Brasil, 50% interest in Novvi Limited, 51% interest in Janus Brasil, 50% interest in Vertical and other investments. Equity in earnings of associates decreased to negative R$4.4 million in the fiscal year ended December 31, 2016 from R$8.0 million in the fiscal year ended December 31, 2015, primarily due to the translation adjustment of international operations results.

Equity in earnings of joint ventures

Equity in earnings of joint ventures includes our 50% interests in Raízen Energia and Raízen Combustíveis. Equity income increased to R$1,570.1 million in the fiscal year ended December 31, 2016 from R$695.2 million in the fiscal year ended December 31, 2015, as a result of the factors explained in detail above for the segments Raízen Energia and Raízen Combustíveis, which are not consolidated into our financial statements but equity accounted for, in accordance with IFRS 11.

Financial results, net

Financial results, net in the fiscal year ended December 31, 2016 totaled a net financial expense of R$3,055.8 million compared with a net financial expense of R$2,184.5 million in the fiscal year ended December 31, 2015, an increase of R$871.3 million, or 39.89%, mainly due to the higher balance (net of derivatives) and cost of debt pegged to the CDI rate.

Cost of gross debt. The total cost of gross debt (which includes interest expenses, exchange variation and derivative gain or loss) increased R$776.1 million, or 45.76%, mainly associated with the higher cost of debt indexed to the CDI rate, which was partially offset by the lower expenses related to the Perpetual Bonds, which benefitted from the real appreciation in the period. Additionally, the increase in gross debt is part of Cosan’s liability management process, which aims to lengthen the debt profile via the U.S.$650 million issue of Senior Notes 2027 and the partial repurchase of the Senior Notes 2018 and 2023.

Interest income. Interest income grew R$189.4 million, due to the higher average cash balance referred mainly to the receipt of the sale of Radar and the assignment of credit amounts deriving from severance claims.

Other charges and monetary variations. Other charges and monetary variations went up 34.14% to R$1,118.2 million, chiefly due to monetary variation of the obligation due to preferred shareholders, mark-to-market loss from equity instruments, leases and concession agreements. Banking expenses, fees and other expenses increased R$170.6 million, mainly impacted by a financial discount granted on the sale of credit amounts deriving from a suit for damages filed against the federal government.

100

Income tax (expense) benefit

Income tax expenses amounted to R$61.7 million for the fiscal year ended December 31, 2016, compared to R$30.4 million benefits in the fiscal year ended December 31, 2015. In the fiscal year ended December 31, 2016, the effective tax rate was 11.10%, which was lower than the nominal corporate tax rate of 34%, mainly due to interest in earnings of investees of R$532.3 million, which was partially offset by differences in tax rates on losses of overseas companies of R$150.2 million, interest on shareholders’ equity of R$45.5 million, non-deductible expenses of R$28.1 million and unrecognized tax losses of R$185.1 million relating to subsidiaries of Cosan Logística.

Net income attributable to owners of the Parent

As a result of the foregoing, net income attributable to our owners was R$277.8 million in the fiscal year ended December 31, 2016, compared to R$405.6 million in the fiscal year ended December 31, 2015, a decrease of 31.51% after deducting net income attributable to non-controlling interests of R$181.2 million and R$394.0 million in the fiscal year ended December 31, 2016 and the fiscal year ended December 31, 2015, respectively.

B. Liquidity and Capital Resources

Overview

Our financial condition and liquidity are influenced by several factors, including:

• our ability to generate cash flow from our operations;

• the level of our outstanding indebtedness and related accrued interest, which affects our net financial expenses;

• prevailing Brazilian and international interest rates, which affect our debt service requirements;

• exchange rate variations, which can affect both our U.S. dollar-denominated debt and our U.S. dollar-denominated supply agreements; and

• credit ratings, including factors that may materially influence credit ratings, implications of potential changes in ratings and management’s expectations; and covenant compliance, including the implications of a breach of financial or other covenants and our capacity for additional borrowing under its covenants.

Our cash needs have traditionally consisted of working capital requirements, servicing of our indebtedness, capital expenditures related to investments in operations, maintenance and expansion of plant facilities, as well as acquisitions. Our sources of liquidity have traditionally consisted of cash flows from our operations and short-and long-term borrowings. We have financed acquisitions through seller financing, third-party financing or capital contributions by our shareholders. We believe our current working capital is sufficient for our present requirements and would expect to meet any potential shortfalls in our working capital needs through short- and long-term borrowings, capital contributions by our shareholders, or offerings of debt or equity securities in the domestic and international capital markets.

In the fiscal years ended December 31, 2017, 2016 and 2015, the cash flow used in investing activities was funded mainly by increased borrowing. As of December 31, 2017, our consolidated cash and cash equivalents (including marketable securities) amounted to R$8,408.5 million, compared to R$5,791.2 million for the fiscal year ended December 31, 2016, and R$4,111.3 million for the fiscal year ended December 31, 2015.

On December 31, 2017, Cosan S.A. had a positive consolidated working capital of R$2,788.6 million and profit for the year of R$1,510.5 million. On December 31, 2017, Cosan Logística had a positive consolidated working capital of R$898.1 million and loss for the period of R$264 million. Nevertheless, it presented a net cash generation from operations of R$2,307.8 million, whereby Cosan Logistica made investments in the modernization of its fleet and improved the railway network in the amount of R$2,045.4 million, in line with its business plan.

101

Cash Flows

The following table sets forth certain of our cash flow data for the periods indicated:

Consolidated	For the Fiscal Year Ended December 31,
	2017		2016		2015
	(in R$ millions, except percentages)
Cash flows from operating activities		4,088.1		3,635.4		3,350.6
Cash flows used in investing activities		3,577.4		727.0		1,003.1
Cash flows from financing activities		565.7		1,819.3		542.6

Cash Flow from Operating Activities

The net cash flows generated by operating activities in the fiscal year ended December 31, 2017 were R$4,088.1 million, compared to net cash flows generated by operating activities of R$3,635.4 million in the fiscal year ended December 31, 2016, reflecting higher operational performance of our business. In addition, changes in assets and liabilities were higher than the previous year, with a total amount of R$766.9 million in the fiscal year ended December 31, 2017, compared to R$474.2 million in the fiscal year ended December 31, 2016. These increases were partially offset by higher net cash tax payments in the fiscal year ended December 31, 2017 (R$90.1 million) as compared to the fiscal year ended December 31, 2016 (R$83.4 million). For the fiscal year ended December 31, 2015, net cash flows generated by operating activities were of R$3,350.6 million.

Cash Flow Used in Investing Activities

Net cash flows used in investing activities were R$3,577.4 million in the fiscal year ended December 31, 2017, compared to R$727 million in the fiscal year ended December 31, 2016. This variation was mainly attributable to acquisition of property, plant and equipment, intangible assets and investments of R$2,457.5 million and marketable securities of R$2,331.2 million. This change was partially offset by dividends received from joint ventures of R$1,346.5 million. For the fiscal year ended December 31, 2015, cash flows used in investing activities were R$1,003.1 million. See also “—Capital Expenditures.”

Cash Flow from Financing Activities

Net cash flows used in financing activities were R$565.7 million in the fiscal year ended December 31, 2017, compared to net cash flows from financing activities of R$1,819.3 million in the fiscal year ended December 31, 2016. This variation was primarily due to the return of operating cash flow to our shareholders through dividend payments of R$1,089.8 million and payment of loans, borrowings, debentures and financing leases of R$6,073.1 million, partially offset by long-term debt raised of R$6,248.7 million. For the fiscal year ended December 31, 2015, net cash flows from financing activities were R$542.6 million.

Indebtedness

As of December 31, 2017, our outstanding debt totaled R$21,688.9 million, of which R$3,903.3 million was short-term debt. Our debt consisted of R$11,312.5 million in local currency-denominated debt and R$10,376.4 million in foreign currency-denominated debt.

Our total debt of R$21,688.9 million at December 31, 2017 increased 18.27% as compared to our total debt of R$18,338.5 million at December 31, 2016, primarily reflecting Cosan S.A.’s liability management strategy. Our short-term debt, composed of our current portion of long-term debt and interest accrued, represented 18% of our total indebtedness at December 31, 2017. Our U.S. dollar-denominated debt at December 31, 2017 represented 45.67%, and our British pound sterling-denominated debt represented 2.17% of our total indebtedness. Our secured debt at December 31, 2017 represented 4.8% of our total indebtedness, mostly in the form of land mortgage deeds, assignment/pledge of credit rights, machinery and equipment, sugar and ethanol.

Certain of our long-term debt agreements require us or certain of our subsidiaries, as applicable, to comply with certain financial covenants, including our U.S.$500 million 5.950% senior notes with maturity in 2024, Rumo’s U.S.$750 million 7.375% senior notes with maturity in 2024, Rumo’s 5.875% senior notes due 2025, our U.S.$200 million and U.S.$300 million 8.25% perpetual notes, our U.S.$500 million 5.00% notes with maturity in 2023 and our R$850 million 9.50% notes with maturity in 2018, which limits the ability of our subsidiaries to, among other things, enter into certain transactions with shareholders or affiliates, make certain restricted payments (including, in certain circumstances, payments of dividends), engage in a merger, sale or consolidation transactions and create liens.

102

We and our subsidiaries are subject to certain restrictive financial covenants set forth in existing loans and financing agreements. For the fiscal year ended December 31, 2017, we and our subsidiaries were in compliance with our debt covenants.

The principal financing activities for the fiscal year ended December 31, 2017 are described below:

• On February 9, 2017, Cosan Logística’s subsidiary, Rumo, completed an offering of 7.375% senior notes due 2024 in an aggregate principal amount of U.S.$750 million. The proceeds of this offering were used to repay certain short-term indebtedness and the remainder (if any) for general corporate purposes.

• On September 20, 2017, we completed an offering of 5.950% senior notes due 2024 in an aggregate principal amount of U.S.$500 million.

Working Capital

As of December 31, 2017, we had working capital of R$4,011.6 million, compared to R$2,139.9 million as at December 31, 2016. The difference between the position at December 31, 2017 and December 31, 2016 was mainly attributable to an increase in marketable securities. See also “—Overview.”

Our capital expenditures in property, plant and equipment, including acquisitions (net of cash acquired) were R$2,457.5 million during the fiscal year ended December 31, 2017, compared to R$2,190.6 million during the fiscal year ended December 31, 2016. For the fiscal year ended December 31, 2015 our capital expenditures were R$2,012.3 million.

In 2017, 2016 and 2015, our capital expenditures consisted primarily of the following:

• Rumo. Rumo has focused on investments in the renovation of assets, in particular its locomotives and railcar fleet, through the purchase of new rolling stock to replace assets in poor condition of use.

• Comgás. Comgás has invested in the expansion of its network and has also undertaken network support investments in order to reinforce, restore and renovate the existing distribution network.

• Moove. Moove has invested in modernization and maintenance of its assets.

The following table sets forth our capital expenditures for the fiscal years ended December 31, 2017, 2016 and 2015:

D. Trend Information

The following list sets forth, in our view, the most important trends, uncertainties and events that are reasonably likely to continue to have a material effect on our revenues, income from continuing operations, profitability, liquidity and capital resources, or that may cause reported financial information to be not necessarily indicative of future operating results or financial condition:

• The ongoing economic and political crisis in Brazil may adversely affect the performance of the Brazilian economy;

• Developments and the perception of risk in other countries may adversely affect the Brazilian economy;

• Potential inflation increases that could cause an increase in interest rates and lower growth in lending activities;

• Continued market volatility and instability that could affect our revenues;

• Restrictive regulations or government intervention;

• Decreased liquidity in domestic and international capital markets;

• Tax policies that could decrease our profitability; and

• Currency fluctuation and exchange rate controls that could have an adverse impact on international investors.

For more information, see “Item 3. Key Information—D. Risk Factors” where we present the risks we face in our business that may affect our commercial activities, operating results or liquidity.

E. Off-Balance Sheet Arrangements

We have entered, in the normal course of business, into several types of off-balance sheet arrangements, as set forth below:

Acquisition of assets

Following the postponement of the 2014 Five-Year Tariff Review 2014 as a result of the publications of ARSESP Resolutions No. 493 and No. 494, both of which were published on May 27, 2014, which approved the “Tariff Review Process of Gas distribution companies in the State of São Paulo, defining event schedule,” and the “Provisional adjustment of marketing margins of São Paulo Gas Company—COMGÁS,” we are not subject to any set regulatory commitment to purchase assets as of December 31, 2017, 2016 and 2015.

Gas transportation

Comgás has take-or-pay purchase contracts, effective through December 2019, with gas suppliers which establish minimum daily purchases of gas volumes. Were Comgás to consume a volume of gas below its contractual obligation, the Comgás would be required to pay for the shortfall between consumption and the required minimum contractual volumes; however, it could recover this credit (through consumption) over the remaining contract period. Amounts paid but not consumed by Comgás were recognized as “Other non-current assets” in the statement of financial position (R$291.3 million for the fiscal year ended December 31, 2017, R$244 million for the fiscal year ended December 31, 2016 and R$204.7 million for the fiscal year ended December 31, 2015).

Operating Leases

At December 31, 2017, 2016 and 2015, the future minimum lease payments under non-cancellable operating leases are as follows:

	December 31, 2017		December 31, 2016		December 31, 2015
	(in thousands of reais)
Less than one year		10,358		11,545		22,788
Between one and five years		35,136		31,050		24,364
More than five years		10,708		10,576		13,528
Total		56,202		53,171		60,680

C. Summary of Significant Differences of Corporate Governance Practices

The NYSE Corporate Governance Rules provide that we are required to disclose any significant differences on our corporate governance practices from those required to be followed by U.S. companies under NYSE listing standards. We have summarized these significant differences below.

We are permitted to follow practice in Bermuda in lieu of the provisions of the NYSE Corporate Governance Rules, except that we will be required to have a qualifying audit committee under Section 303A.06 of the Rules, or avail ourselves of an appropriate exemption. In addition, Section 303A.12(b) provides that our chief executive officer is obligated to promptly notify the NYSE in writing after any of our executive officers becomes aware of any material non-compliance with any applicable provisions of the NYSE Corporate Governance Rules.

113

Majority of Independent Directors

NYSE Rule 303A.01 provides that each U.S. company that is listed on the Exchange must have a majority of independent directors. Bermuda corporate law does not require that we have a majority of independent directors. Under our by-laws, at least 40% of our directors are required to be independent directors; which requirement increases to 60% following the death or permanent incapacitation of Mr. Rubens Ometto Silveira Mello.

Separate Meetings of Non-Management Directors

NYSE Rule 303A.03 provides that the non-management directors of each U.S. company that is listed on the Exchange must meet at regularly scheduled executive sessions without management. We are not required to have such executive sessions for the non-management directors under Bermuda law.

Nominating and Corporate Governance Committee

NYSE Rule 303A.04 provides that each U.S. company that is listed on the Exchange must have a nominating/corporate governance committee composed entirely of independent directors. We are not required to have such a committee under Bermuda law. We believe that, pursuant to our bye-laws, the role of a nominating committee is generally performed by our board of directors and that the role of the corporate governance committee is generally performed by either our board of directors or our senior management.

Compensation Committee

NYSE Rule 303A.05 provides that each U.S. company that is listed on the Exchange must have a compensation committee composed entirely of independent directors. We are not required to have such a committee under Bermuda law.

Audit Committee

NYSE Rule 303A.06 and the requirements of Rule 10A-3 of the SEC provide that each listed company is required to have an audit committee consisting entirely of independent members that comply with the requirements of Rule 10A-3. In addition, the company must have an internal audit function and otherwise fulfill the other requirements of the NYSE rules and Rule 10A-3 of the SEC.

While we are not required under Bermuda law to have an audit committee, we have formed a committee that has the following responsibilities:

• pre-approve services to be provided by our independent auditor;

• review auditor independence issues and rotation policy;

• supervise the appointment of our independent auditors;

• discuss with management and auditors major audit, accounting and internal control issues;

• review quarterly financial statements prior to their publication, including the related notes, management’s report and auditor’s opinion;

• review our annual report and financial statements;

• provide recommendations to the board on the audit committee’s policies and practices;

• review recommendations given by our independent auditor and internal audits and management’s responses;

• provide recommendations on the audit committee’s bye-laws; and

114

• the receipt, retention and treatment of complaints received by the issuer regarding accounting, internal controls or auditing matters.

For details of the membership of our Audit Committee, see “—A. Directors and Senior Management—Board of Directors—Committees of the Board of Directors—Audit Committee.”

Equity Compensation Plans

NYSE Rule 303A.08 provides that shareholders must be given the opportunity to vote on all equity compensation plans and material revisions thereto, with certain limited exemptions as described in the rule. Under Bermuda law, shareholder pre-approval is not required for the adoption of equity compensation plans nor any material revision thereto.

Corporate Governance Guidelines

NYSE Rule 303A.09 provides that each U.S. listed company must adopt and disclose its corporate governance guidelines. We do not have a similar requirement under Bermuda law. In addition, we have adopted a written policy of trading of securities and disclosure matters.

Code of Business Conduct and Ethics

NYSE Rule 303A.10 provides that each U.S. listed company must adopt and disclose a code of business conduct and ethics for directors, officers and employees and promptly disclose any waivers of the code for directors or executive officers. Although not required under Bermuda law, the Company has adopted a code of business conduct and ethics for directors, officers and employees as provided for in NYSE Rule 303A.10, which has been filed with the SEC.

D. Employees

As of December 31, 2017, we had 11,230 employees. The following table sets forth the number of our total employees by segment for the dates indicated:

We believe that we have good relations with our employees and the unions that represent them. Collective bargaining agreements to which we are party have either one-year or two-year terms, are subject to annual renewal and are subject to changes in Brazilian law. We apply the terms of bargaining agreements entered into with the unions equally to unionized and non-unionized employees.

Our total annual payroll was R$1,985.2 million as of December 31, 2017, which includes a provision for vacations, and bonuses, taxes and social contributions.

We offer our employees, including our executive officers, various benefits, which are provided in accordance with the employee’s position in our company. Benefits include medical (including dental) assistance, meal and transport vouchers, life insurance, maternity leave, scholarships and funeral assistance and nursery assistance.

Equity-Based Compensation Plans

Cosan Limited

Equity Incentive Plan

We have adopted a Cosan Limited equity incentive plan. We have reserved up to 5% of our issued and outstanding class A common shares as of the granting date for issuance under our equity incentive plan. The plan is intended to attract, retain and motivate our directors, officers and employees, to link compensation to the overall performance of the company in order to promote cooperation among our diverse areas of business and to create an ownership interest in the company with respect to these directors, officers and employees in order align their interests with the interests of our shareholders. No shares or options have been issued or granted in connection with this incentive plan.

Long-Term Retention Plan

We have adopted a long-term retention plan, or the “LTR Plan,” aimed at rewarding and retaining certain high-level executives of strategic importance to the Company who may be granted certain share based awards as may be determined by our board of directors. Participation in the LTR Plan is subject to selection by our Board of Directors. Under the LTR Plan, each beneficiary may receive, subject to the terms and conditions of the LTR Plan, up to 1% each of the total number of issued and outstanding shares of Cosan Limited (the precise amount being granted is at the discretion of the Board of Directors). Beneficiaries may receive the equivalent of the share grant in cash, at the discretion of our Board of Directors. Any grants of shares or cash under the LTR Plan are to be delivered to the beneficiary over the course of a period of up to 10 years. Currently, five key executives are each eligible to receive share grants or cash of up to 1% each of our issued share capital over the course of the next 10 years, in an amount to be defined by our Board of Directors annually.

The executives who participate in the Plan have entered into a Terms of Governance between themselves and the Company which will regulate their rights, privileges, protections and obligations as shareholders of the Company should our chairman, Rubens Ometto Silveira Mello, no longer be with the Company.

As of December 31, 2017, an aggregate of 533,546 shares have been granted in 2017 to executives participating in the LTR Plan. Concurrently with the abovementioned grant of shares, our Board of Directors granted certain executives an additional payment of U.S.$316,425 in cash. In addition, on September 29, 2017, our board of directors decided to reward executives for their contribution to the performance of the Company by granting them 255,000 share appreciation rights. The rights entitle the executives to a cash payment after five years of service. The amount payable will be determined based on the increase share price between the grant date and the vesting date. The rights must be exercised on vesting date and will expire if not exercised on that date.

116

Cosan S.A.

At the shareholder’s meeting held on July 29, 2011, the guidelines for the outlining and structuring of the stock option compensation plan for Cosan S.A.’s officers and employees were approved. These guidelines authorize the issuance of shares accounting for up to 5% of Cosan S.A.’s total capital. This stock option plan was established to attract and retain officers and key employees, offering them the opportunity to become shareholders in Cosan S.A. On August 18, 2011, Cosan S.A.’s board of directors approved a total stock option grant of up to 12,000,000 common shares to be issued or treasury shares held by Cosan S.A., corresponding to 2.41% of Cosan S.A.’s share capital at that time. On August 18, 2011, 9,825,000 options related to the shared based compensation were granted.

If a holder of stock options ceases to be an executive officer, manager or eligible employee for any reason (other than redundancy, death, retirement or permanent incapacitation), after partially exercising his or her option to purchase Cosan’s common shares, the options that have not yet been exercised will be extinguished as of the date that the holder ceases to be an executive officer, manager or eligible employee.

Cosan stock options held by Cosan’s executive officers may, at their option, be canceled and converted into awards of Cosan Limited, and, as a result, we will comply with the limit of shares we have reserved for our equity incentive plan. Cosan’s stock options will be converted based upon a ratio equal to the initial offering price of our common stock, divided by the weighted average stock price of Cosan’s common stock for a specified period immediately preceding the date of the completion of our initial public offering. The converted securities, if unvested, generally will continue to vest over their original vesting periods.

On May 21, 2013, the board of directors of Cosan S.A. approved the second program of Stock Option Purchase or Subscription of Shares – Calendar Year 2013. As part of this approval, the board of directors of Cosan S.A. determined that the beneficiaries may purchase or subscribe common shares of the Cosan S.A., with grants of up to 1 million shares, which options may be exercised after at least five years from the approval at a price of R$45.22 per share (such price to be adjusted pursuant to the IPCA until the date of the subscription or purchase).

Cosan Logística

On January 2, 2017, Cosan Logística granted 1,522,220 and 1,513,180 shares, respectively, of the share-based compensation plan. These will be transferred in full and free of charge 5 years from the approval of the grant, in a quantity adjusted by the number proportional to the dividends paid in the period, according to the employment status and incentives met by the relevant beneficiary at Rumo S.A. under the terms of each share-granting program.

Most decisions by the supervisory boards require a quorum of two members and are generally made by a majority present and voting. Certain significant matters, however, will require the consent of five of the six or four of the six members, as the case may be.

The matters which require the consent of five of the six or four of the six members include but are not limited to the following:

• setting the general strategic guidelines and direction for the Joint Venture and amending and updating the Joint Venture’s business plan;

• appointing, removing or terminating members of the executive board;

• determining the compensation and benefits of certain employees;

• amending key policies and procedures of the Joint Venture;

• adopting or amending the annual and capital budgets;

• instituting or settling any litigation or dispute in excess of a specified sum or which could damage the reputation of the Joint Venture, Cosan or Shell;

• selling, assigning, transferring or encumbering assets of the Joint Venture outside of the ordinary course of business in excess of a specified amount;

• entering into transactions (including mergers, stock purchases or asset purchases) of which the value or purchase price exceeds a specified amount;

• making capital expenditures in excess of a specified amount, subject to certain exceptions;

• submitting any matters, including financial statements and reports, to the meeting of the Joint Venture’s shareholders;

• entering into any contract, agreement or instrument outside of the ordinary course of business and that provides for payments in excess of a specified amount;

• entering into material amendments, modifications or waivers or terminating any contract where payment obligations exceed a specified amount;

• making any decision to borrow money or guarantee the payment or performance of any obligation in excess of a specified amount or to prepay indebtedness of a specified amount;

121

• creating any encumbrance over or the issuance of any Joint Venture securities or any option relating to any Joint Venture securities, subject to certain exceptions;

• approving the credit limits or the extension of credit to any customer of the Joint Venture in excess of a specified amount; and

• entering into, amending, terminating or renewing any insurance policy.

If the supervisory boards cannot reach a decision with respect to a matter that is their responsibility, one representative of Cosan and one representative of Shell will meet to attempt to resolve the matter. Any decision by these shareholder representatives must be unanimous. If the shareholder representatives cannot reach a joint decision, no decision would be taken or effected and the status quo would prevail.

Additionally, certain matters require the consent of the shareholders of the Joint Venture. These matters include, but are not limited to, removal of any member of a supervisory board; approval of supervisory board resolutions relating to dividend payments; approval of management accounts and financial statements; amendments to the bye-laws of Raízen Energia or Raízen Combustíveis; and issuance of securities by the Joint Venture.

The shareholders’ agreements provide that a shareholder may lose certain governance rights if it fails to make capital contributions that may be required pursuant to the shareholders’ agreements or to make certain payments required pursuant to the Framework Agreement. If the delinquent party pays or contributes such amounts in full within a specified cure period, the respective governance rights of the shareholders are returned to their original state prior to any such delinquency.

The day-to-day management of the Joint Venture is conducted by the executive boards, composed of a chief executive officer and other senior executive officers. The shareholders’ agreements set forth the various functions and responsibilities of the chief executive officer and senior management, as well as the actions that may be taken by the executives without the approval of the relevant supervisory board.

In November 2016, Cosan S.A. and Shell executed amendments to certain agreements between them to remove the fixed date call options over Raízen Energia and Raízen Combustíveis shares exercisable in 2021 and 2026, and replace them with certain call and put options exercisable by Shell or Cosan S.A. upon the occurrence of certain events including, among others: (i) fundamental breaches of the obligations provided for in the agreements governing the Joint Venture; (ii) breach of anticorruption laws, (iii) insolvency or bankruptcy of a party, (iv) change of control, and (v) in the event of the death or disability of Cosan S.A.’s current Chairman, Mr. Rubens Ometto Silveira Mello. Moreover, Cosan S.A. and Shell agreed to renew the existing lock-up period for five years from the date of the execution of the amendment, following which the parties may sell their shares in each of Raízen Energia and Raízen Combustíveis subject to compliance with certain preemption rights in each other’s favor.

Legal Proceedings

We are party to numerous legal proceedings, the most relevant of which are further described below.

Probable Losses

In the ordinary course of our business, we are party to a number of legal proceedings for which we deem the risk of loss as probable for which we have recorded provisions in an aggregate amount of R$1,348.2 million as of December 31, 2017 and R$1,268.6 million as of December 31, 2016. Provisions relating to probable losses are categorized into tax, civil and labor, described below.

Tax. We recorded provisions of R$479.5 million and R$501.2 million for tax proceedings involving probable risk of loss as of December 31, 2016 and December 31, 2017, respectively. The principal tax proceedings for which the risk of loss is probable are described below:

• FINSOCIAL – Offset requests. The Brazilian federal tax authorities refused to ratify requests made by Cosan Lubrificantes to set-off undue payments of FINSOCIAL, a social tax levy, against other tax debts. Based on a favorable judicial decision, Mobil acquired the right to set-off FINSOCIAL tax payments against certain COFINS payments. However, a subsequent favorable judicial decision granted Cosan Lubrificantes immunity against the enforcement of such COFINS-related debts. Therefore, previous set-off requests were extinguished, since the COFINS debts ceased to exist, and Cosan Lubrificantes sought to reuse the relevant tax credits to set-off other tax debts. However, the Brazilian federal tax authorities refused to ratify part of the set-offs, claiming that the COFINS immunity applied only to the fiscal year during which the lawsuit was filed (i.e., in 1992). No judicial deposits were made for these proceedings. The provision for this proceedings was R$269.3 million as of December 31, 2016 and R$280.2 million as of December 31, 2017. The risk of loss is classified as probable.

• Social Security Contributions – In June 2010, Raízen Energia filed an ordinary action challenging the obligation to accrue the social security contributions tax based on gross revenue. Currently, the case records are in the Court of Appeals awaiting judgment of the appeal filed by the Brazilian federal government against a favorable first level decision. The risk of loss is classified as probable and as of December 31, 2017, Raízen had recorded provisions in connection with this proceeding in the aggregate amount of R$310.3 million and had judicially deposited the same amount (the two together therefore cancel each other out). The alleged underlying facts occurred both before and after the formation of the Raízen joint venture on April 1, 2011 and, therefore, these amounts are subject to reimbursement by Raízen’s shareholders for a portion of any loss in the event of an adverse decision.

125

• ICMS - We have provisioned amounts relating to tax assessments issued against us by the tax authorities related to several types of ICMS credits, including: (a) an assessment notice related to ICMS payments for raw material purchases which are considered for “use and consumption” and therefore, according to the tax authorities, are not eligible for compensation, and (b) an assessment, as sole obligor, for allegedly disregarding withholding obligations of ICMS taxes in relation to a tolling agreement, arising from an agricultural partnership between the Company’s sugarcane plants and Central Paulista Ltda. Açúcar e Álcool.; (c) an assessment notice related to ICMS payments related to the exportation of crystallized sugar not considered under tributary immunity; (d) assessment notice related to the ICMS under tributary substitution regime; (e) ICMS assessment notice related to interstate operations taxed as internal transactions. No judicial deposits have been made in connection with these proceedings. These provisions amounted to R$84.8 million as of December 31, 2016 and R$99.4 million as of December 31, 2017.

Civil, regulatory, environmental and other claims. Cosan, its subsidiaries and jointly-controlled entities are parties to a number of civil legal claims related to (1) indemnity for material and moral damages; (2) termination of different kinds of agreements (3) public civil claims related to sugarcane stubble burning; (4) environmental matters; and (5) other matters. Provisions for civil, regulatory and environmental claims as of December 31, 2016 amounted to R$344 million and R$375.6 million as of December 31, 2017. As of December 31, 2017, R$180.3 million in judicial deposits were made for civil and environmental claims, and this figure was R$173.9 million as of December 31, 2016. Cosan, its subsidiaries and jointly-controlled entities are also parties to a number of regulatory legal proceedings related to (1) collection of fines by the ANTT; (2) discussions on the tariff ceiling imposed by the ANTT; and (3) certain other matters.

Labor claims. Cosan, its subsidiaries and jointly-controlled entities are also parties to a number of labor claims filed by former employees and service providers challenging, among other matters, the payment of overtime, night shift premiums and risk premiums, the recognition of employment relationships and the reimbursement of discounts from payroll, such as social contribution and trade union charges. Additionally, we are involved in several labor administrative and judicial proceedings such as labor investigations and class actions filed by the labor prosecutor’s office regarding alleged non-compliance with certain labor regulations, including work and safety rules, labor conditions and work environment, and social assistance plans. Moreover, we entered into certain consent orders (Termos de Ajustamento de Conduta) with Brazilian authorities and in the event we fail to comply with such consent orders, we could be subject to fines. Provisions for labor claims as of December 31, 2016 amounted to R$445.0 million and R$471.3 million as of December 31, 2017.

Possible Losses

In addition, there are currently certain legal proceedings pending in which we are involved for which we have not recorded provisions, as we deem the likelihood of loss as possible. If adverse decisions are rendered against us in any of these legal proceedings, our results of operations or financial condition could be materially and adversely affected. The aggregate amount involved in proceedings for which our risk of loss has been deemed possible as of December 31, 2017 totaled R$ 15,914.8 million, of which R$11,065.8 million, R$2,865.6 million, R$1,061.9 million, R$543 million and R$378.5 million were related to tax, civil, labor and regulatory and environmental claims, respectively. The principal proceedings for which we deem the risk of loss as possible are described below:

• Withholding Income Tax – capital gain ExxonMobil. The Brazilian federal tax authorities issued a tax assessment against Cosan Lubrificantes, as the responsible party for the collection of withholding income tax allegedly due on the capital gains earned by ExxonMobil International Holdings B.V. and ExxonMobil Brasil Holdings B.V., companies incorporated outside of Brazil, in connection with the sale of cooperatives headquartered in the Netherlands. According to the Brazilian tax authorities, the real intention of Cosan Lubrificantes was to acquire Esso Brasileira de Petróleo Ltda. The updated amount under discussion in these proceedings is R$1,128 million, including interest and a 150% penalty, of which R$823.9 million is classified as a possible risk of loss as of December 31, 2017 and R$776 million as of December 31, 2016. Currently, Cosan Lubrificantes is awaiting judgment of the motion for clarification regarding the decision that in part permitted the special appeal filed in the Superior Chamber of Tax Appeals.

126

• Goodwill on the acquisition of Esso. The Brazilian federal tax authorities issued two tax assessments against Cosan Lubrificantes for the collection of corporate income taxes relating to 2009, 2010 and 2011 due to the write off of goodwill expenses accrued in connection with the acquisition of cooperatives which controlled Esso Brasileira de Petróleo Ltda. According to Cosan Lubrificantes, the updated amount under discussion is of R$586 million, including interest and a 150% fine, of which R$419.6 million is classified as a possible risk of loss and R$166.4 million is classified as a remote risk of loss in the fiscal year ended December 31, 2017. Currently, Cosan is awaiting a decision on the motion for clarification filed against the partially favorable decision rendered by the Administrative Court of Tax Appeals. In addition, on December 14, 2017, Cosan Lubrificantes received a tax assessment notice, relating to 2012, due to the write off of goodwill expenses accrued in connection with the acquisition of cooperatives which controlled Esso Brasileira de Petróleo Ltda. According to Cosan Lubrificantes, the updated amount under discussion is R$176.9 million, including interest and a 150% fine, of which R$138.6 million is classified as a possible risk of loss and R$38.3 million is classified as a remote risk of loss as of December 31, 2017. Cosan Lubrificantes is awaiting judgment of the administrative court.

• ICMS – inventory differences. The tax authority of the state of São Paulo issued two tax assessment notices, one against Raízen Energia and one against Cosan S.A., in February, 2012 relating to ICMS taxes on inventory differences. A decision rendered by the First Administrative Trial Court was partially favorable with respect to one of these tax assessments, which is currently pending a decision by the second administrative trial court. In relation to the other tax assessment, the first and second administrative trial court’s decisions were unfavorable and a decision on the appeals filed is currently pending. The total amount involved in such proceedings is R$764.5 million. The risk of loss is partially classified as remote (R$672 million) and partially classified as possible (R$92.4 million) in the fiscal year ended December 31, 2017.

• Environmental Civil Class Action. Cosan is being sued by the Municipality of Ulianópolis, by means of the civil class action No. 0000749-68.2011.8.14.0130, for environmental damages related to alleged irregular waste disposal in a landfill located in the Municipality of Ulianópolis, in the state of Pará. Eight other companies are involved in the same lawsuit, and the plaintiff intends to declare all of them as jointly liable for restoring the environmental damage involved therein. The plaintiff seeks R$145.7 million but the specific amount needed to restore the damage cannot be estimated. It is also important to highlight that more than 50 companies are involved in the same matter by means of other lawsuits and a civil investigation currently being held by the State of Pará’s Public Prosecutor’s Office. Therefore, it is expected by some of these companies that any settlement or condemnation in this matter should comprise all of them. The lawsuit is currently suspended due to a plea from the Public Prosecutor’s Office. According to the Company’s information, the amount under discussion in these proceedings is R$156.5million, of which R$14.3 million is classified as a possible risk of loss and R$142.2 million is classified as a remote risk of loss.

• Malha Paulista – MS Teixeira Prumo Engenharia. Rumo’s subsidiary Malha Paulista is currently a party to a public civil action before the labor courts. This proceeding originated in an inspection of the company MS Teixeira, which was hired by the company Prumo Engenharia, Rumo’s subcontractor. The inspecting authority alleged that workers for MS Teixeira were working in conditions that were degrading and analogous to slavery. Prumo Engenharia fully assumed the responsibility for the condition of the employees, including labor and contractual liabilities and all losses resulting from the alleged unlawful working conditions maintained by its subcontractors, and the dismissal agreements of such employees were approved by the Ministry of Labor, without any participation by Rumo. Moreover, a criminal investigation against Rumo in the matter was filed, which was later dismissed with the acquittal of Malha Paulista. Notwithstanding the foregoing, the Labor Prosecutors’ Office filed a public civil action solely against Rumo, which Rumo is fully contesting. Rumo was ordered (in both the first instance and on initial appeal) to comply with several obligations relating to workplace conditions, and pay collective moral damages, as well as fines of R$100,000 per breach or per worker in the event of future labor breaches. Rumo has appealed to the Regional Appeal Court, but the appeal was dismissed. Rumo appealed again to the Superior Labor Court and the appeal is currently pending. In Rumo’s assessment, an adverse outcome in this lawsuit could result in losses of approximately R$26.9 million, and adversely affect Rumo’s reputation. The risk of loss in this proceeding is estimated as possible.

127

• Brado Logística. This is an arbitration relating to the Brado Shareholders’ Agreement. Rumo may be required to either make payment of the amount under dispute (R$544 million as of December 31, 2017), or issue new shares in an amount corresponding to the amount involved, which may result in the dilution of its existing shareholders, including Cosan Logística. We estimate that the risk of Rumo being required to make payment of the amount involved is remote, but that the risk of us being required to issue new shares is possible. FI-FGTS is also a signatory to the Brado Shareholders’ Agreement and, although it is not a party to the proceedings involving the shareholders of Brado, it has been granted the same option as was granted to other parties to the Brado Shareholders’ Agreement. The exercise of the option by FI-FGTS may occur between the fifth and the seventh anniversary of the date of signing of the Brado Shareholders’ Agreement (entered on August 5, 2013). For further information, please see “Item 3. Key Information—D. Risk Factors—Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate—The exercise of an option granted under the shareholders’ agreement of one of Rumo’s subsidiaries, Brado Logística, may have a material adverse effect on Rumo’s financial condition or result in a dilution of Rumo’s shareholders’ equity interest.”

• Rumo Arbitration. Rumo is involved in a confidential arbitration in which indemnification claims in an amount of approximately R$430 million have been made by the plaintiff (a sugar trading company). The parties are awaiting the constitution of the arbitration tribunal. Rumo’s counsel has assessed the risk of loss as possible.

• Lawsuits concerning the economic-financial balance of leasing and concession contracts. Rumo’s subsidiaries Malha Paulista and Rumo Malha Oeste S.A., or Malha Oeste, are parties to several lawsuits with the Brazilian government relating to the restoration of the economic-financial balance of the contracts entered into by the parties under the concession for certain railroad networks and the leasing of the related equipment. The Brazilian government filed actions to collect unpaid installments of the leasing and concession contracts. Malha Paulista and Malha Oeste, in turn, filed their own lawsuits seeking the restoration of the economic-financial balance of the contracts. In both cases, the trial court rendered interlocutory decisions authorizing Malha Paulista and Malha Oeste to guarantee the maturing installments by letters of guarantee issued by financial institutions. The trial court ruled in Malha Oeste’s favor on December 19, 2014, and partially in Malha Paulista’s favor on October, 2015. The parties filed appeals against both decisions. The appeal of Malha Paulista was partially accepted, in order to guarantee the right to reimburse counsel involved for the fees incurred. As of the date of this annual report, the appeal regarding Malha Oeste is still pending the resolution of certain requests for clarification in connection with the Malha Paulista lawsuit. The aggregate payments alleged to be owed by Malha Paulista and Malha Oeste total R$2,597 million. Accordingly, an adverse outcome in either of these lawsuits could result in significant losses to Rumo. In particular, Malha Paulista and Malha Oeste would be required to pay the installments guaranteed by letters of guarantee. The risk of loss in these proceedings is estimated as possible.

• Portofer lawsuit. The Federal Prosecutor’s Office filed public civil action against ALL and Malha Paulista, relating to irregularities in the public bidding of the railroad network of Porto de Santos. According to the Federal Prosecutor’s Office, the government leased the railroad network to FERROBAN, FERRONORTE and FERROVIA NOVOESTE without having held prior bidding proceedings. ALL and Malha Paulista were included in this lawsuit as defendants because they are successors to these companies. Certain allegations of anticompetitive practice have been made in connection with these proceedings, based on the fact that the concession agreement related to the railroad network within the Port of Santos was directly awarded to FERROBAN, FERRONORTE and FERROVIA NOVOESTE without holding a bidding process, which the Federal Prosecutor’s Office believes should have been held. However, in the complaint, the Federal Prosecutor’s Office did not allege that anticompetitive practices were committed by the defendants themselves. Accordingly, even if the outcome of the lawsuit is negative for the defendants, the defendants will still be able to enter into contracts with the Brazilian public sector, and, if the concession agreement is deemed void, the government will be required to indemnify the defendants for investments made unless the Federal Prosecutor’s Office can prove that such persons acted in order to avoid a bidding procedure. In any event, it is likely that the renewal clause of the agreement will be deemed void. An adverse outcome in this lawsuit could result in the loss of ALL’s and Malha Paulista’s concession, a new bidding process being held in relation to the railroad network of Porto de Santos and the restitution of any unamortized investment made by ALL in the network. The trial court dismissed the injunction request of the Federal Prosecutor’s Office, pursuant to which the Federal Prosecutor’s Office requested the commencement of a new bidding proceeding and that the Brazilian government be prevented from renewing the current concession contract. ALL and Malha Paulista presented a defense in connection to this case, arguing the maintenance of the current concession agreement. The court denied the injunction requested by the Federal Prosecutor’s Office. The risk of loss in these proceedings is estimated as possible.

• Rumo/ALL Investigation. During the course of 2016, Rumo became aware of certain press reports alleging that improper payments to government officials were made by former employees of ALL (prior to being acquired by Rumo) in connection with an investment by Fundo de Investimento do Fundo de Garantia do Tempo de Serviço, or “FI-FGTS,” in Rumo’s indirect subsidiary Brado Logística and in ALL. As a result of these allegations, Rumo has engaged external legal counsel and consultants to conduct an internal investigation. The report of the investigation was submitted to the Federal Prosecutor’s Office (without being made available to the Company, in accordance with the terms of the engagement). At this time, we can neither predict the outcome of the internal investigation, the consequences of any findings or any measures that may be taken by local authorities, any of which may have a material adverse effect on Rumo. See “Item 3. Key Information—D. Risk Factors—Risks Related to Our Businesses, the Operations of Our Joint Venture, and Industries in Which We Operate—We cannot predict the outcome of an investigation into the conduct of former employees of ALL prior to its acquisition by Rumo.”

• Tax assessment notices. We have also received a number of tax assessment notices, including (i) an administrative tax assessment notice on amortization of goodwill expense, the possible amount of which is R$618.9 million, and which represents a possible risk of loss; (ii) a tax assessment notice related to goodwill amortization deductions from 2011 to 2012 in a possible amount of R$93.1 million; (iii) a tax assessment notice relating to exchange variation and interest incurred as the tax authorities understand that certain corporate transactions carried out were intended to postpone the settlement of debt contracted abroad through the issuance of perpetual bonds in order to reduce the positive result of exchange variation, the amount of which is R$76.4 million with a possible risk of loss. These three notices of infraction are being questioned at the administrative level; (iv) Cosan Lubrificantes has received an assessment notice drawn up for the collection of IRPJ and CSLL for the 2011 and 2012 calculation periods, for the exclusion of Net Income for the period, referring to the amortization of goodwill on the acquisition of investments valued by shareholders’ equity, the amount of which R$178.4 million with a possible risk of loss. This goodwill is the responsibility of Cosan Lubrificantes and was contributed to Raízen Combustíveis, and the assessment was a reflection of the assessment related to the period from 2009 to 2011.

• Comgás tax assessment notice. Comgás has received a tax assessment notice in an amount of R$284.4 million in relation to income tax withheld at source (IRRF) on capital gains. As a result of certain contractual arrangements, this contingency is the responsibility of the former controlling shareholder of Comgás.

• Goodwill Comgás. Comgás received a tax assessment notice on April 7, 2016 requiring Comgás to pay certain additional income tax and social contribution on net income arising in connection with the amortization of goodwill on certain investments in the 2013 to 2014 calculation periods. According to Comgás, the updated amount under discussion was R$939 million, including interest and a 150% fine, of which R$696.1 million was classified as a possible risk of loss and R$242.5 million is classified as a remote risk of loss as of December 31, 2017.

Certain Tax Proceedings

We are parties to certain other tax proceedings, including the following primary proceedings:

• Tax assessment notices issued to require additional income tax, social contribution, PIS and COFINS, for the calendar years 2005 to 2008 as a result of the following alleged violations: (a) improper deduction from taxable income and CSLL calculation basis of financial costs arising from loans with foreign financial institutions, (b) improper exclusion from taxable income and CSLL calculation basis of financial income from securities issued by the Government of Austria and the Government of Spain, (c) no inclusion, in the income tax and CSLL calculation basis, of gains earned in swap operations, and the absence of taxation of financial income resulting from these contracts by PIS and COFINS, (d) improper exclusion from taxable income and the CSLL calculation basis, using PIS and COFINS credits, and (e) improper exclusion from taxable income and CSLL calculation using deferred CSLL. A reduction in tax assessment resulted from a favorable CARF judgment that involved the cancellation of most tax requirements, since the classification for remote losses changed.

129

• Malha Paulista has received a tax assessment notice relating to the absence of taxation of PIS and COFINS on revenues from mutual traffic and rights of passage invoiced against Malha Norte in the amount of R$33 million as of December 31, 2017. The chance of loss is considered possible as tax already has been collected by the concessionaire.

• Malha Paulista had part of its IRPJ credit balance not accepted based on the argument that it would not be entitled to IRRF compensation on swap transactions. The amount involved is R$72.5 million.

• We are a party to certain legal proceedings related to INSS payment with a possible risk of loss, as follows: (a) proceedings regarding the legality and constitutionality of Normative Instruction MPS/SRP Nº 03/2005, which restricted the constitutional immunity over social contributions on export revenues through direct sales, consistent with the manner exports made via trading companies that are now taxed, in an amount of R$365 million as of December 31, 2017; (b) assessment of SENAR (Rural apprenticeship scheme) social contribution on direct and indirect exports, in which the tax authorities disregard the right to constitutional immunity, in an amount of R$15 million as of December 31, 2017.

• The Brazilian tax authorities issued tax assessments in 2011 and 2013 against Rumo concerning: (a) amortization expense disallowance based on future profitability, as well as financial expenses; and (b) non-taxation of supposed capital gain on the disposal of equity interest in a Company of the same group, in an amount of R$512.1 million as of December 31, 2017.

• Rumo has received an assessment relating to the disregard of the tax benefits of REPORTO (PIS and COFINS suspension), on the grounds that the locomotives and freight cars purchased in 2010, 2011 and 2012 were used outside the limits of the port. Therefore, Rumo was assessed to pay PIS and COFINS, as well as a fine corresponding to 50% of the value of acquired assets, in the amount of R$429.2 million as of December 31, 2017.

• The tax authorities have partially rejected the installment requests for federal tax debts made by Malha Sul and Intermodal, arguing that the Net Operating Losses, or “NOLs,” offered by the companies were not sufficient to discharge their existing debts. The amount involved is R$110.1 million as of December 31, 2017. The probability of loss is considered possible, since the NOLs existed and were available for such use.

Judicial Deposits

In accordance with court orders concerning certain tax, civil and labor lawsuits, we had bank judicial deposits in an aggregate amount of R$766.1 million as of December 31, 2017.

Criminal Environmental Claims

Cosan, its subsidiaries and jointly-controlled entities are parties to seven criminal environmental lawsuits and are investigated in 26 environmental police inquiries in process in the States of São Paulo, Pará, Rio Grande do Sul, Mato Grosso do Sul, Paraná and Santa Catarina. The main crimes alleged would be noise pollution; contamination of soil and rivers; burning; deforestation of native forest; emission of pollutants into the atmosphere and irregular transport of dangerous products. Among these criminal environmental proceedings, five lawsuits have a possible chance of loss and could result in a penalty for Cosan; two lawsuits have a remote chance of loss; 24 lawsuits have a possible chance of loss; one police inquiry has a remote chance of loss; and in one police inquiry we are only named as interested parties because we reported the alleged criminal behavior.

Criminal Proceedings Involving Members of Our Management

Certain members of our management are parties to criminal proceedings, as follows:

Mr. Rubens Mello

Mr. Rubens Ometto Silveira Mello, in his capacity as a representative of Usina da Barra S.A. – Açúcar e Álcool (the former corporate name of Raízen Energia), was named a defendant in a complaint filed on September 24, 2007 alleging the crimes of disobedience and pollution in connection with the burning of sugarcane by the company in contravention of a judicial decision in a public civil class action which banned this practice in the region. In a motion, Mr. Mello pleaded (1) the illegitimacy of his status as a defendant, given that he did not participate in the alleged conduct and was not the owner or lessor nor did he exercise control over the area in which the alleged conduct took place, (2) the fact that the alleged conduct does not constitute a crime, given that the notice regarding the prohibition against the burning of sugarcane was not given by the competent authority and (3) that the right to the controlled burning of sugarcane in the region was reestablished in the context of the public civil class action and that the allegations with regards to the crimes of disobedience and pollution should therefore be disregarded. The motion was granted in part in relation to the suspension of the criminal proceeding until the rendering of a final judgment in the public civil action. While the statute of limitations with respect to the crime of pollution was tolled, the statute of limitations with respect to the crime of disobedience was not suspended and has expired. Accordingly, the complaint with respect to the crime of pollution was remanded to the state authorities in order for the investigations in connection with crime of pollution to continue. As of the date of this annual report, this criminal proceeding remains suspended pending a final decision in the related public civil class action as to whether the crime of pollution was in fact committed. As of the date of this annual report, such final decision is still pending. In the event the criminal proceeding is permitted to advance, Mr. Mello will be subject to the applicable criminal penalties. In the opinion of counsel responsible for Mr. Mello’s defense, compelling legal arguments exist that would support dismissal of the charges against Mr. Mello, and the likelihood of a decision favorable to Mr. Mello is probable.

Mr. Rubens Mello and Mr. Guilherme Cerqueira

Mr. Cerqueira, an executive officer of Raízen Centroeste Açúcar e Álcool Ltda. (formerly known as Cosan Centro-Oeste Açúcar e Álcool Ltda.), and Mr. Mello, while an executive officer of Raízen Centroeste Açúcar e Álcool Ltda., were named defendants, together with Raízen Centroeste Açúcar e Álcool Ltda., in a complaint filed on July 20, 2011 alleging artificial price fixing of fuel and the formation of a cartel for the purpose of establishing regional market control. In their defense, Mr. Mello and Mr. Cerqueira maintain that their status as defendants in the proceeding is not proper given the lack of proof of their involvement in the alleged illicit acts. Mr. Mello and Mr. Cerqueira also maintain that the increase in the price of ethanol resulted solely from market forces (i.e., that the increase in the price of ethanol did not result from criminal conduct, but rather the lawful exercise of a recognized constitutional right of free enterprise). The claim was accepted and the criminal proceedings are currently in an initial phase. The defendants filed a motion of habeas corpus, which was partially granted on May 18, 2017 with regards to the crime of conspiracy but rejected with regards to the crime of cartel formation. Decision on the appeals is still pending. On February 21, 2018, the judge ordered a stay of the action and the cancellation of scheduled hearings pending a decision from the Brazilian Supreme Court of Justice (Supremo Tribunal de Justiça). In the event the criminal proceeding is permitted to proceed, Mr. Mello and Mr. Cerqueira may be subject to criminal penalties, including the inability to continue to serve as our directors or officers. In the opinion of counsel responsible for Mr. Mello and Mr. Cerqueira’s defense, the likelihood of a decision favorable to Mr. Mello and Mr. Cerqueira is probable.

Mr. Rubens Mello, Mr. Marcos Lutz and Mr. Pedro Mizutani

Mr. Rubens Mello, Mr. Marcos Lutz and Mr. Pedro Mizutani were named as defendants in a criminal complaint filed on August 28, 2014 to determine whether they have committed tax evasion in connection with the alleged failure to adequately pay state value added taxes (ICMS). The determination as to whether outstanding taxes are in fact due is at issue in a separate tax collection enforcement proceeding that is independent of the criminal proceeding. Bank letters of credit and insurance guarantees have been deposited with the relevant court in order to secure the amount in controversy. Given the fact that the crime of tax evasion requires there to be an actual loss to the tax authorities, such deposits have generally been interpreted by the Brazilian courts to eliminate criminal liability given that there would no longer exist a direct or indirect risk of harm to the public treasury and the allegedly illicit conduct of the defendants would no longer constitute a crime. This understanding, however, may change depending on the judge’s final decision. In view of the foregoing, the defense filed a motion requesting that the criminal proceedings (which are currently suspended) be terminated for lack of cause. The criminal action is currently suspended and there is still an appeal pending with regards to the filing of the accusation. In the opinion of counsel responsible for the defense, the likelihood of a decision favorable to the defendants is possible. In any event the payment of the amounts due would be sufficient to extinguish liability.

131

Mr. Marcelo Martins

Mr. Marcelo Eduardo Martins is a defendant in a criminal suit filed by the Public Prosecutor of the state of Bahia on July 4, 2016, regarding the crime of tax evasion for the alleged failure to pay ICMS by Votorantim Cimentos N/NE S/A prior to Mr. Martins joining Cosan. A reply to the indictment has already been filed and the case is being analyzed. The related tax enforcement is duly guaranteed by means of a bank guarantee letter. In the opinion of counsel responsible for the defense, the likelihood of a decision favorable to the defendant is possible.

Mr. Ricardo Dell Aquila Mussa and Mr. Nelson Roseira Gomes Neto

Mr. Ricardo Dell Aquila Mussa and Mr. Nelson Roseira Gomes Neto are among the defendants in a criminal proceeding initiated by Nike International Ltd. and Nike do Brasil Comércio e Participações Ltda. in connection with alleged crimes against intellectual property and trademarks (as provided for in Brazilian law) relating to the alleged unauthorized use of a registered trademark, as well as the importing of products marked with brands illegally reproduced or copied from a third party (in each case, in their respective capacities prior to joining Raízen and Comgás, respectively). All defendants have already presented their respective defenses, and a favorable decision of acquittal was granted by a first instance court on November 13, 2017. The prosecution has appealed. According to counsel responsible for this lawsuit, the chance of a decision favorable to the defendants is probable.

Dividends and Dividend Policy

Dividend Rights

Cosan Limited is a holding company and can only pay dividends to the extent, if any, that funds are received from our subsidiaries. Our dividend policy is similar to the current dividend policy of our principal subsidiaries, Cosan S.A. and Cosan Logística. Brazilian corporate law requires that the by-laws of a Brazilian company specify a minimum percentage of the available income for the annual distribution of dividends, known as the mandatory dividend, which must be paid to shareholders as either dividends or interest attributable to shareholders’ equity. We intend to pay cash dividends, representing on an annual basis 25% of our annual consolidated net income, to holders of class A common shares and class B common shares in proportion to the number of shares held by them unless our board of directors has determined, in its discretion, that such distribution would not be advisable or appropriate in light of our financial condition or we are unable to meet applicable statutory solvency requirements under Bermuda law.

Our board of directors may, in its discretion, amend or repeal our dividend policy. You may not receive the level of dividends provided for in the dividend policy or any dividends at all due to a number of factors, such as:

• we are a holding company, and therefore, our ability to pay dividends will depend on our ability to receive distributions from our subsidiaries;

• our subsidiaries may become subject to covenants restricting their ability to distribute dividends under credit facilities, term loans or other indebtedness;

• any imposition of restrictions on conversions and remittances by the Brazilian government could hinder or prevent us from converting into U.S. dollars or other foreign currencies and remitting abroad dividends of our Brazilian subsidiaries;

• our shareholders have no contractual or other legal rights to dividends pursuant to Bermuda law; and

• we may not have sufficient cash to pay dividends due to changes in our operating earnings, working capital requirements and anticipated cash needs.

Under Bermuda law, a company’s board of directors may declare and pay dividends from time to time unless there are reasonable grounds for believing that the company is or would, after the payment, be unable to pay its liabilities as they become due or that the realizable value of its assets would thereby be less than the aggregate of its liabilities and issued share capital and share premium accounts. Under our bye-laws, each class A common share and class B common share is entitled to dividends if, as and when dividends are declared by our board of directors, subject to any preferred dividend right of holders of any preference shares. There are no restrictions on our ability to transfer funds (other than funds denominated in Bermuda dollars) in or out of Bermuda or to pay dividends to U.S. residents who are holders of our common shares.

We expect to have sufficient available cash to pay dividends in accordance with our dividend policy. We do not, however, plan to pay dividends in the event that we do not generate sufficient cash from operations. In addition, we will not pay dividends if we believe that such payment will limit or preclude our or our subsidiaries’ ability to pursue growth opportunities. Although our bye-laws and Cosan’s by-laws do not restrict us from borrowing funds to pay dividends, we do not intend to borrow funds to pay dividends.

132

The dividend rights attaching to our class A common shares and class B common shares are not cumulative in the event that we do not, for any reason, pay dividends on those shares.

Any cash dividends payable to holders of our common shares quoted on the NYSE will be paid to Mellon Investors Services LLC, our transfer agent in the United States, for disbursement to those holders.

Cosan S.A. Dividend Policy

Brazilian corporate law and Cosan’s by-laws require that Cosan distributes annually to its shareholders a mandatory minimum dividend, unless Cosan’s board of directors notifies the shareholders that such distribution is not advisable in light of Cosan’s financial condition as reflected in Cosan’s consolidated financial statements. The basis of the mandatory dividend is a percentage of the net income, as adjusted pursuant to the Brazilian Corporation Law. Under our by-laws, a minimum of 25% of our adjusted net income should be intended for distribution and payment to our shareholders as mandatory dividend. However, the payment of mandatory dividends to our shareholders may be limited to the amount of realized net income in a given year, provided the difference is recorded as an unrealized income reserve.

We are required by the Brazilian Corporation Law and our by-laws to hold an annual shareholders’ meeting no later than four months after the end of each fiscal year, at which time the allocation of the results of operations in any year and the distribution of an annual dividend are reviewed. The distribution of annual dividends is based on our audited financial statements prepared for the immediately preceding fiscal year.

Calculation of Adjusted Net Income

At each annual shareholders’ meeting, our board of directors is required to recommend how to allocate our net income for the preceding fiscal year, which recommendation our board of executive officers initially submits to our board of directors for approval.

This allocation is subject to approval by our common shareholders. The Brazilian Corporation Law defines “net income” for any fiscal year as our net income after income taxes for that fiscal year, net of any accumulated losses from prior fiscal years and any amounts allocated to employees’ participation in our net income in that fiscal year. Under the Brazilian Corporation Law, our adjusted net profit available for distribution are equal to our net profit in any fiscal year, reduced by amounts allocated to our legal reserve and other applicable reserves, and increased by any reversals of reserves that we constituted in prior years.

Reserve Accounts

Under the Brazilian Corporation Law and our by-laws, we are required to maintain a legal reserve. In addition, we are permitted by the Brazilian Corporation Law to establish the following discretionary reserves:

• a contingency reserve for an anticipated loss that is deemed probable in future years. Any amount allocated in a previous year must be reversed in the fiscal year in which the loss had been anticipated if the loss does not occur as projected or charged off in the event that the anticipated loss occurs;

• a reserve for investment projects, in an amount based on a capital expenditure budget approved by our shareholders;

• an unrealized income reserve; and

• a tax incentive investment reserve, included in our capital reserve accounts, in the amount of the reduction in our income tax obligations due to government tax incentive programs.

Allocations to each of these reserves (other than the legal reserve) are subject to approval by our common shareholders voting at our annual shareholders’ meeting.

The Brazilian Corporation Law provides that the legal reserve and the tax incentive investment reserve may be credited to shareholders’ equity or used to absorb losses, but these reserves are unavailable for the payment of distributions in subsequent years.

The amounts allocated to the other reserves may be credited to shareholders’ equity and used for the payment of distributions in subsequent years.

133

Cosan Logística’s Dividend Policy

Cosan Logística’s dividend policy is the same as of Cosan S.A.

Joint Venture’s Dividend Policy

The shareholders’ agreement between Cosan S.A. and Shell also establish the dividend policy of the Joint Venture. The dividend policy states that the Joint Venture seeks to maximize the amount of profits to be distributed to its shareholders in a manner consistent with its leverage ratio objectives and capital investment requirements. The supervisory boards must propose, and the shareholders approve, an allocation of the net profit of the Joint Venture in accordance with the shareholders’ agreements. The shareholders’ agreements provide that net profit is subject to the following allocation order:

• first, up to 5% of net profit to the respective company’s legal reserve, which may not exceed a specified amount, the lower of 20% of the respective company’s capital stock or 30% of the capital plus any capital surplus;

• second, a variable amount of net profit to each shareholder based on certain tax attributes contributed by it to the Joint Venture; Cosan is entitled to receive preferential dividends equivalent to the amount of any tax savings from the amortization of goodwill it contributes to the Joint Venture. Similarly, Shell is entitled to receive preferential dividends equivalent to the amount of any tax savings from the amortization of accumulated losses that it contributes to the Joint Venture;

• third, a nominal amount of net profit to the holders of certain preferred shares;

• fourth, 1% of net profit to the shareholders;

• fifth, a variable amount, capped at a specified percentage of net profit, to the respective company’s statutory reserve for operations and projects, such amount not to exceed 80% of net profits or 80% of the respective company’s share capital; and

• sixth, the distribution of the remaining amount of net profit to be determined by the shareholders.

Brazilian Taxation

Dividends paid by Cosan to us are currently not subject to withholding income tax in Brazil, to the extent that such amounts are related to profits generated since January 1, 1996. The only exception would be for amounts related to 2014 tax statements. In this case, considering new tax legislation enacted in May 2014, if the amounts calculated using the accounting criteria in force in December 2007 (i.e., without IFRS effects) exceed a certain exemption limit, they would be taxed at a rate of 25%. Cosan did not surpass the exemption limit.

Brazilian tax laws permit Cosan to make distributions to shareholders of interest on shareholders’ equity and treat those payments as a deductible expense for purposes of calculating Brazilian income tax and social contributions. For tax purposes, this interest is limited to the daily pro rata portion of the TJLP, as determined by the Brazilian Central Bank quarterly, and the amount of the deduction is limited to the largest of (1) 50% of net income (after social contributions but before income tax and the amount to be distributed as interest on shareholders’ equity) related to the period in respect of which the payment is made; and (2) 50% of the sum of retained profits and profit reserves as of the date of the beginning of the period in respect of which the payment is made. A payment to us of interest on shareholders’ equity is subject to withholding income tax at the rate of 25%.

B. Memorandum and By-laws

General

We are a limited liability exempted company incorporated under the laws of Bermuda on April 30, 2007. We are registered with the Registrar of Companies in Bermuda under registration number EC 39981. Our registered office is located at Crawford House, 50 Cedar Avenue, Hamilton HM 11, Bermuda.

The objects of our business are set forth in our memorandum of association and provide that we have unrestricted objects and powers and rights including to:

• import, export, produce and sell ethanol, sugar, sugarcane and other sugar by-products;

• distribute and sell fuel and other fuel by-products;

• produce and market electricity, steam and other co-generation by-products;

• render technical services related to the activities mentioned above; and

• hold equity interests in other companies.

There have been no bankruptcy, receivership or similar proceedings with respect to us or our subsidiaries.

Issued Share Capital

Under our bye-laws, the holders of our class A common shares and class B common shares will be offered the preemptive right to purchase, in the first instance, on a pro rata basis according to their ownership interests, additional shares in the event of any increase in share capital. However, this preemptive right may be waived by (1) a majority of our board of directors in the case of an offering (whether or not registered under the Securities Act) or (2) a majority of the independent directors on our board of directors in any circumstance.

Pursuant to and in accordance with the Notice to the Public dated June 1, 2005 issued by the Bermuda Monetary Authority, there is no limitation on the right of non-residents of Bermuda to hold our shares as long as we remain listed on the NYSE or another appointed stock exchange.

Common Shares

Holders of class A common shares are entitled to one vote per share on all matters submitted to a vote of shareholders in general meeting. Holders of class B series 1 common shares or class B series 2 common shares are entitled to 10 votes per share on all matters submitted to a vote of shareholders in general meeting, except as otherwise provided by our bye-laws.

Except for the conversion provisions relating to our class B common shares, holders of our class A common shares and class B common shares have no redemption, conversion or sinking fund rights. Unless a different majority is required by law or by our bye-laws, resolutions to be approved by holders of common shares require approval by a simple majority of votes cast at a meeting at which a quorum is present.

In the event of our liquidation, dissolution or winding-up, the holders of class A common shares and class B common shares are entitled to share equally and ratably in our assets, if any, remaining after the payment of all of our debts and liabilities, subject to any liquidation preference on any outstanding preference shares.

138

Preference Shares

Under our bye-laws, we may, subject to the affirmative vote of a majority of our board of directors and, in certain circumstances as provided for in our bye-laws, a majority of our class A common shares and class B common shares, each voting as a separate class, establish one or more series of preference shares having such number of shares, designations, dividend rates, relative voting rights, conversion or exchange rights, redemption rights, liquidation rights and other relative participation, optional or other special rights, qualifications, limitations or restrictions as may be fixed. Such rights, preferences, powers and limitations as may be established could also have the effect of discouraging an attempt to obtain control of us. There are no outstanding preference shares, and we have no present plans to issue any preference shares.

Dividend Rights

For information concerning dividend rights of our class A common shares, class B series 1 common shares and class B series 2 common shares, see “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividends and Dividend Policy.”

Tag-along Rights

Following the consummation of our initial public offering, no person or group of persons (other than a holder of class B series 1 common shares) may, in a transaction or series of transactions, acquire, directly or indirectly, the beneficial ownership of class A common shares representing more than 15% of our issued and outstanding common shares from any person or otherwise acquire control over our company, unless the terms and conditions of such transaction or transactions include an offer by the acquiring person or group of persons to the holders of all other class A common shares or class B common shares to acquire at the option of each applicable shareholder, all or any part of the respective shares owned by such shareholder. The price per share paid by the acquiring person or group of persons will be equivalent to the greater of (1) the highest price per share paid by the acquiring person or group of persons to acquire any such class A shares representing 15% of our issued and outstanding common shares or control, as applicable and (2) a price determined based on an appraisal report. The tag-along tender offer must be launched promptly after closing of the sale that triggers application of the tag-along provision and be completed within 60 days after the consummation of the transaction or series of transactions. In the event that the tag-along tender offer is not completed within the 60-day period, the holder or holders of the shares acquired in the sale that triggered the preemption rights will not be entitled to vote such shares, and we will be entitled to compel such holder or holders to sell these shares to unaffiliated persons deemed acceptable by a majority of our board of directors at the lower of (A) the lowest acquisition price for the class A common shares and (B) the then prevailing market price on the NYSE or such other stock exchange which constitutes the principal market for the class A common shares on a date selected by our board of directors that is not more than ten trading days on the applicable exchange following the expiration of the 60-day period.

Conversion

Our class A common shares are not convertible into any other shares of our authorized share capital.

Each class B common share is convertible at any time after three years following our initial public offering (August 16, 2007), at the option of the holder, into one class A common share. In addition, each class B common share will, subject to limited exceptions applicable to class B series 1 common shares referred to below, automatically convert into one class A common share upon any transfer of its current beneficial ownership, whether or not for value.

Following the death of Mr. Rubens Ometto Silveira Mello or a determination by 66-2/3% of our board of directors based on the medical determination of two internationally recognized certified physicians that he is permanently mentally incapacitated, the beneficial ownership of class B series 1 common shares may be transferred from him to his immediate family members without resulting in the automatic conversion of those shares into class A common shares. So long as class B common shares are issued and outstanding, in the case of death or permanent incapacitation of Mr. Rubens Ometto Silveira Mello, the following actions or events will be subject to approval by a majority of the then independent members of our board of directors, in addition to any other approval of shareholders or members of our board required by Bermuda law or our bye-laws:

• appointment of the chief executive officer of our company or any of its subsidiaries (including successors thereof);

• changes to the core business strategy of our company or any of its subsidiaries;

• change of name or corporate purpose of our company or any of its subsidiaries;

• amendments to any rights of the class B series 1 common shares;

139

• any recapitalization, stock split, combination, reclassification or similar action affecting equity interests in our company or any of its subsidiaries;

• redemption, capital reduction or other acquisition for value of any shares of equity interests in our company or any of its subsidiaries;

• any transaction or series of transactions resulting in a spin-off, delisting, merger, amalgamation, reorganization or combination of or by our company or any of its subsidiaries with, or any acquisition of, another person involving an amount in excess of U.S.$250 million;

• any sale, lease, assignment, transfer or other disposition of assets valued, in the aggregate, in excess of U.S.$250 million;

• any voluntary liquidation, reorganization, dissolution or winding-up of, or a voluntary filing for bankruptcy protection by our company or any of its subsidiaries;

• the approval of the limit of the compensation of members of the board of directors or executive officers of our company or any of its subsidiaries;

• the making of any investment in excess of U.S.$250 million other than investments in the ordinary course of business;

• entering into any Joint Venture, partnership or any similar arrangement other than in the ordinary course of business;

• any related-party transactions;

• the incurrence of any liens on properties valued, in the aggregate, in excess of U.S.$250 million;

• amendment of the provisions of any of the foregoing actions or events; and

• agreeing to, or otherwise committing to take, any of the foregoing actions.

Mr. Rubens Ometto Silveira Mello may also transfer his class B series 1 common shares to a trust, corporation, partnership or limited liability company in which he and, following his death or permanent incapacitation, a member or members of his immediate family, directly or indirectly, retain sole dispositive power and exclusive voting control with respect to such entity and the class B series 1 common shares held by such entity. In addition, any such trust, corporation, partnership, or limited liability company that directly holds class B series 1 common shares may distribute those shares to its respective partners, members or owners (which may further distribute the class B series 1 common shares to their respective partners, members or owners) without triggering a conversion to class A common shares, provided that Mr. Rubens Ometto Silveira Mello and, following his death or permanent incapacitation, his immediate family members continue to hold sole dispositive power and exclusive voting control over the class B series 1 common shares.

Class B common shares also will automatically convert into class A common shares when the aggregate outstanding class B series 1 common shares represent less than 45% of our total voting power in respect of the issued and outstanding share capital in the company. In addition, class B series 2 common shares will automatically convert into class A common shares if all the class B series 1 common shares convert into class A common shares.

Once transferred and converted into class A common shares, class B common shares will not be reissued. No class of common shares may be subdivided or combined unless the other class of common shares concurrently is subdivided or combined in the same proportion and in the same manner.

Transfer of Shares

Our board of directors may, in its discretion and without assigning any reason, refuse to register the transfer of a share that it is not fully paid. Our board of directors may also refuse to register the transfer of a share unless the instrument of transfer for such share is duly stamped (if required by law), is in respect of one class of shares, is in favor of less than five persons jointly and is accompanied by the relevant share certificate (if one has been issued) and such other evidence of the transferor’s right to make the transfer as our board of directors shall reasonably require. Any transfer of beneficial ownership of class B series 1 common shares or class B series 2 common shares not registered with the company will be null and void. For a period of three years following our initial public offering (August 16, 2007), holders of our class B series 2 common shares may not transfer less than all of the class B series 2 common shares that they own. Subject to these restrictions as are more fully set out in our bye-laws a holder of shares in the company may transfer the title to all or any of such holder’s shares in the company by completing a form of transfer in such form as our board of directors may reasonably approve. The instrument of transfer must be signed by the transferor and transferee, although in the case of a fully paid share, our board of directors may accept the instrument signed only by the transferor. The board may also accept mechanically executed transfers.

140

Meetings of Shareholders

Under Bermuda law, a company is required to convene at least one general meeting of shareholders in each calendar year. Bermuda law provides that a special general meeting of shareholders may be called by the board of directors of a company and must be called upon the requisition of shareholders holding not less than 10% of the paid-up capital of the company as of the date of deposit carries the right to vote. Bermuda law also requires that shareholders be given at least five days’ advance notice of a general meeting, but the accidental omission to give notice to, or the non-receipt of a notice by, any person entitled to receive notice does not invalidate the proceedings at the meeting. Our bye-laws provide that the chairman of the board of directors may call an annual general meeting or a special general meeting. Special general meetings of the shareholders may also be convened by our board of directors.

Under our bye-laws, at least 10 clear days’ notice of an annual general meeting or a special general meeting must be given to each shareholder entitled to receive notice of such meeting. This notice requirement is subject to the ability to hold such meetings on shorter notice if notice is served pursuant to Bermuda law in the manner provided by the Companies Act 1981. The quorum required for a general meeting of shareholders is two or more persons present in person or by proxy and entitled to vote representing the holders of more than 45% of the aggregate voting power of the shares in the Company which by their terms carry the right to vote.

Any action required to be taken at a meeting of shareholders except in the case of the removal of auditors or directors may be taken without a meeting and without vote if a consent or consents in writing, setting forth the action so taken, is signed by the holders of issued and outstanding shares of the company, their proxy or corporate representative representing the percentage of votes required if the resolution had been voted on at a meeting of the shareholders. Notice of any resolution in writing shall be given to all shareholders entitled to attend a vote at a shareholder meeting.

Access to Books and Records and Dissemination of Information

Members of the general public have the right to inspect the public documents of a company available at the office of the Registrar of Companies in Bermuda. These documents include the company’s memorandum of association and any alteration to its memorandum of association. The shareholders have the additional right to inspect the bye-laws of the company, minutes of general meetings and the company’s audited consolidated financial statements, which audited financial statements must be presented at the annual general meeting unless waived in accordance with the provisions of the Companies Act 1981. The register of shareholders of a company is also open to inspection by shareholders and by members of the general public without charge. The register of shareholders is required to be open for inspection for not less than two hours in any business day (subject to the ability of a company to close the register of shareholders for not more than 30 days in a year in accordance with the procedure set out in the Companies Act 1981). A company is required to maintain its share register in Bermuda but may, subject to the provisions of the Companies Act 1981, establish a branch register outside Bermuda. A company is required to keep at its registered office a register of directors and officers that is open for inspection for not less than two hours in any business day by members of the general public without charge. Bermuda law does not, however, provide a general right for shareholders to inspect or obtain copies of any other corporate records.

Election and Removal of Directors

Our bye-laws provide that our board of directors must consist of between five and eleven directors or such greater number as the board may determine. Our board of directors currently consists of twelve directors. Our bye-laws provide that at least 40% (and, following the death or permanent incapacitation of Mr. Rubens Ometto Silveira Mello, at least 60%) of the members of our board of directors must be independent (as defined by the rules promulgated by (1) the U.S. Securities and Exchange Commission under the Exchange Act and (2) by the NYSE or any other principal securities exchange on which the class A common shares are so listed).

Our board of directors is divided into three classes that are, as nearly as possible, of equal size. Each class of directors is elected for a three-year term of office, and the terms are staggered so that the term of only one class of directors expires at each annual general meeting. There is also no requirement under Bermuda law or in our bye-laws that our directors must retire at a certain age.

Any shareholder wishing to propose for election as a director a person who is not an existing director must give notice to the company of the intention to propose that person for election. The notice must be given not later than 90 days before the first anniversary of the last annual general meeting, or ten days after the notice of the general meeting, at which the directors will be elected, whichever is earlier.

141

Our bye-laws provide that a director may be removed with or without cause by a majority of the other directors then in office. Our bye-laws also provide that a director may be removed for cause by the affirmative vote of the holders of a majority of the shareholder votes cast at a general meeting at which a quorum is present, provided that notice is given to the director of the shareholders’ general meeting convened to remove the director. A director may be removed without cause upon the affirmative vote of the holders of a majority of the aggregate voting power of the shares of the Company which carry the right to vote on all matters submitted to shareholders, provided that notice is given to the director of the general meeting convened to remove the director, which notice must contain a summary of the facts justifying the removal and must be served on the director not less than fourteen days before the meeting. As long as a director has made a written request deposited at the registered office of the Company pursuant to the Companies Act 1981, a director is entitled to attend the general meeting and be heard at any general meeting called for his removal.

So long as a quorum remains in office, our board of directors may fill any casual vacancy occurring.

Proceedings of Board of Directors

Our bye-laws provide that our business is to be managed and conducted by our board of directors. Bermuda law permits both individual and corporate directors and there is no requirement in our bye-laws or Bermuda law that directors hold any of our shares.

The remuneration of our directors is determined by our board of directors, and there is no requirement that a specified number or percentage of “independent” directors must approve any such determination. Our directors may also be paid all travel, hotel and other expenses properly incurred by them in connection with our business or their duties as directors.

Provided that he or she discloses a direct or indirect interest in any contract or arrangement with us as required by Bermuda law, our bye-laws provide that a director is entitled to be counted in the quorum, but may not vote in respect of any such contract or arrangement in which he or she is interested. Under Bermuda law, a director (including the spouse or children of the director or any company (other than a company which is a holding company or a subsidiary of the company making the loan) of which such director, spouse or children own or control, directly or indirectly, more than 20% of the total capital or loan debt) cannot borrow from us without the consent of any shareholders holding in the aggregate not less than 90% of the total voting rights of all shareholders having the right to vote at any general meeting of the shareholders.

Waiver of Claims by Shareholders; Indemnification of Directors and Officers

Our bye-laws contain a provision by virtue of which our shareholders waive any claim or right of action that they may have, both individually and on our behalf, against any director or officer in relation to any action or failure to take action by such director or officer, except in respect of any fraud or dishonesty of such director or officer. We understand that, in the opinion of the staff of the SEC, the operation of this provision as a waiver of the right to sue for violations of U.S. federal securities laws would likely be unenforceable in U.S. courts.

Our bye-laws also indemnify our directors and officers in respect of their actions and omissions, except in respect of their fraud or dishonesty, which cannot be indemnified in accordance with the Companies Act 1981.

Amalgamations, Mergers and Other Business Combinations

Under Bermuda law, the amalgamation, merger or other business combination of a Bermuda company with another company (other than certain affiliated companies), unless the bye-laws otherwise provide requires the amalgamation or other business combination to be approved by a majority of the Bermuda company’s board of directors and by a majority of 75% of those voting at the general meeting of the Bermuda company. The quorum for the shareholder approval is two persons holding or representing at least one-third of the issued shares of the Company.

Our bye-laws provide that an amalgamation (but not a merger) or other business combination (as defined in our bye-laws) (other than with a wholly-owned subsidiary) that has been approved by our board of directors must only be approved by a majority of the votes cast at a general meeting of our shareholders at which the quorum must be two persons representing the holders of more than 45% of the aggregate voting power of the paid-up and outstanding shares carrying the right to vote. Any amalgamation or other business combination (as defined in our bye-laws) not approved by our board of directors must be approved by resolution passed by 66 2/3% of all votes attaching to all shares then in issue entitling the holder to attend and vote on the resolution.

142

Specified Transactions Involving Interested Shareholders

Specified transactions include the following:

• any merger, consolidation or amalgamation of the Company with an interested shareholder;

• any disposition or security arrangement with or for the benefit of any interested shareholder involving any of our assets, securities or commitments or those of any subsidiary or any interested shareholder that has an aggregate fair market value and/or involves aggregate commitments of U.S.$250 million or more or constitutes more than 10% of the book value of the total assets or 10% of the shareholders’ equity of the entity in question;

• the adoption of any plan for our liquidation or dissolution or for the discontinuation into another jurisdiction, unless proposed or adopted independently of any interested shareholder; or

• any reclassification of our shares or other securities, or recapitalization, or any merger, consolidation or amalgamation with any of our subsidiaries or any other transaction that has the effect of increasing the proportionate share of any class of shares beneficially owned by an interested shareholder.

In addition to any affirmative vote required by law or our bye-laws, a specified transaction with any interested shareholder will require the affirmative vote of not less than 66 2/3% of the aggregate voting power of the voting shares, voting together as a single class, excluding voting shares beneficially owned by any interested shareholder. Alternatively, a specified transaction may proceed with any affirmative vote required by law or our bye-laws if the following principal conditions are satisfied in relation to common shares: (1) the approval of a majority of directors who are not affiliates of the interested shareholder; and (2) the aggregate amount of the cash and the fair market value as of the date of the consummation of the specified transaction of consideration other than cash to be received by the holder of common shares in such specified transaction shall be at least equal to the highest per share amount paid by the interested shareholder within a two-year period immediately prior to the first public announcement of the proposed specified transaction; or in the transaction in which he or she became such an interested shareholder (whichever is higher) or, if higher, the closing sales prices of such shares on the NYSE on the announcement date for the specified transaction or on the date of the transaction in which he or she became such an interested shareholder.

For purposes of our bye-laws, an “interested shareholder” includes, among others, any person who is or has publicly disclosed an intention to become the beneficial owner of shares representing 10% or more of our aggregate voting power of the voting shares.

Non-Competition Provision Applicable to Brazil

Our bye-laws provide that we will operate and conduct business in Brazil exclusively through Cosan and its subsidiaries, and we will not compete, directly or indirectly, with Cosan in Brazil, unless otherwise approved by a majority of our independent directors.

Amendment of Memorandum of Association and By-laws

Bermuda law provides that the memorandum of association of a company may be amended by a resolution passed at a general meeting of shareholders of which due notice has been given.

Our bye-laws provide that no bye-law will be rescinded, altered or amended, unless it has been approved by a resolution of our board of directors and by a resolution of the shareholders. In the case of rescission, alteration or amendment to the bye-laws relating to interpretation, rights of shares, modification of rights, indemnity of directors and officers, amalgamations and other business combinations, specified transactions involving interested shareholders, our discontinuation into another jurisdiction, tag-along rights and amendment or alterations of bye-laws, the required resolutions must include the affirmative vote of at least 66 2/3% of our directors then in office and holders of at least 66 2/3% of class A common shares and at least a majority of class B common shares then in issue entitling the holder to attend and vote on the resolution, with each class voting separately as a class. In the case of rescission, alteration or amendment to the bye-laws relating to the transmission of shares upon the death of a holder of class B series 1 shares, election of directors, the removal of directors, the increase of share capital and the alteration of share capital, the requisite affirmative votes are a majority of the directors then in office and holders of a majority of each of class A common shares and class B common shares then in issue entitling the holder to attend and vote on the resolution, with each class voting separately as a class.

Under Bermuda law, the holders of an aggregate of not less than 20% in par value of the company’s issued and outstanding share capital or any class thereof and or the holders of not less in the aggregate than 20% of the company’s debentures entitled to object to amendments to the memorandum of association have the right to apply to the Bermuda court for an annulment of any amendment of the memorandum of association adopted by shareholders at any general meeting, other than an amendment which alters or reduces a company’s share capital as provided in the Companies Act 1981.

143

Where such an application is made, the amendment becomes effective only to the extent that it is confirmed by the Bermuda court. An application for an annulment of an amendment of the memorandum of association must be made within 21 days after the date on which the resolution altering the company’s memorandum of association is passed and may be made on behalf of persons entitled to make the application by one or more of their number as they may appoint in writing for the purpose. No application may be made by shareholders voting in favor of the amendment.

Modification of Rights

While we have more than one class of shares and more than one series of class B common shares, the rights attaching to any class or series, unless otherwise provided for by the terms of issue of the relevant class or series, may be modified with the consent in writing of the holders or the approval of the votes cast at a general meeting representing not less than 66 2/3% of the aggregate voting power of the shares in issue and not less than 75% of the aggregate voting power of the issued shares of that class or series, as the case may be. The quorum for any such general meeting will be two or more persons holding or representing by proxy one-third of the voting power of the issued shares of the class or series, as the case may be. Our bye-laws specify that the creation or issue of shares ranking equally with existing shares will not, unless expressly provided by the terms of issue of those new shares, vary the rights attached to existing shares.

Appraisal Rights and Shareholder Suits

Under Bermuda law, in the event of an amalgamation or merger of a Bermuda company with another company, a shareholder of the Bermuda company who is not satisfied that fair value has been offered for such shareholder’s shares may apply to the Bermuda court to appraise the fair value of those shares within one month of the giving of the notice of the shareholders’ meeting called to approve the amalgamation or merger.

Class actions and derivative actions are generally not available to shareholders under Bermuda law. Bermuda courts, however, may permit in certain circumstances a shareholder to commence an action in the name of a company to remedy a wrong to the company where the challenged act would allegedly be beyond the power of the company or illegal. In addition, consideration would be given by a Bermuda court to acts that would allegedly constitute a fraud against the minority shareholders or, for instance, where an act requires the approval of a greater percentage of the company’s shareholders’ voting power than that which actually approved it.

When the affairs of a company are being conducted in a manner which is oppressive or prejudicial to the interests of some or all of the shareholders, one or more shareholders may apply to a Bermuda court, which may make such order as it sees fit, including an order regulating the conduct of the company’s affairs in the future or ordering the purchase of the shares of any shareholders by other shareholders or by the company.

Capitalization of Profits and Reserves

Pursuant to our bye-laws, our board of directors may capitalize any part of the amount of our share premium account or any reserve or fund which is available for distribution by either: (1) paying up unissued shares to be allotted on a pro rata basis to shareholders as fully paid bonus shares; or (2) paying up in full partly paid shares of those shareholders who would be entitled to such sums if they were distributed by way of dividend or other distribution (or partly in one way and partly the other) provided that a share premium account may be applied only in paying up of unissued shares to be issued to such shareholders as fully paid.

Untraced Shareholders

Our bye-laws provide that our board of directors may forfeit any dividend or other monies payable in respect of any shares which remain unclaimed for six years. In addition, we are entitled to cease sending dividend warrants and checks by post or otherwise to a shareholder if such instruments have been returned undelivered to, or left uncashed by, such shareholder on at least two consecutive occasions or, following one such occasion, reasonable inquires have failed to establish the shareholder’s new address. This entitlement ceases if the shareholder claims a dividend or cashes a dividend check or a warrant.

Certain Provisions of Bermuda Law

We have been designated by the Bermuda Monetary Authority as a non-resident for Bermuda exchange control purposes. This designation allows us to engage in transactions only in currencies other than the Bermuda dollar, and there are no restrictions on our ability to transfer funds (other than funds denominated in Bermuda dollars) in and out of Bermuda or to pay dividends to U.S. residents who are holders of our common shares.

144

Pursuant to a Notice to the Public dated June 1, 2005, issued by the Bermuda Monetary Authority, the Bermuda Monetary Authority granted general permission for the issue and subsequent transfer of any shares of a Bermuda company to and between non-residents of Bermuda where any shares of the company are listed and remain so listed on an appointed stock exchange, which includes the NYSE. Approvals or permissions given by the Bermuda Monetary Authority do not constitute a guarantee by the Bermuda Monetary Authority as to our performance or our creditworthiness. Accordingly, in giving such permissions, the Bermuda Monetary Authority will not be liable for the financial soundness, performance or default of our business or for the correctness of any opinions or statements expressed in this annual report.

In accordance with Bermuda law, share certificates are only issued in the names of companies, partnerships or individuals. In the case of a shareholder acting in a special capacity (for example, as a trustee), certificates may, at the request of the shareholder, record the capacity in which the shareholder is acting. Notwithstanding such recording of any special capacity, we are not bound to investigate or see to the execution of any such trust. We will take no notice of any trust applicable to any of our shares, whether or not we have been notified of such trust.

Registrar or Transfer Agent

A register of holders of the class A common shares and class B common shares and any other issued share capital is maintained by Compass Administration Services Ltd. in Bermuda, and a branch register is maintained in the United States by Mellon Investor Services LLC, which serves as branch registrar and transfer agent.

Anti-takeover Effects of our By-laws

Our bye-laws contain provisions that could make it more difficult for a third party to acquire us without the consent of our board of directors. These provisions provide, among other things, for:

• a classified board of directors with staggered three-year terms;

• restrictions on the time period in which directors may be nominated;

• the affirmative vote of a majority of our directors then in office and a majority of all votes cast at a general meeting or, if not approved by a majority of the directors in office, at least 66 2/3% of all votes attaching to all shares then in issue for amalgamation and other business combination transactions; and

• the tag-along rights described under “—Tag-along Rights.”

C. Material Contracts

On September 20, 2017, we entered into an indenture with U.S. Bank National Association as trustee, principal paying agent, transfer agent and registrar in connection with our 5.950% senior notes due 2024.

Except as described above, for the two years immediately preceding the publication of this annual report, we were not a party to any material contract outside the ordinary course of business.

D. Exchange Controls

Investors residing outside Brazil, including institutional investors, are authorized to purchase equity instruments, including BDRs, on a Brazilian stock exchange, provided that they comply with the registration requirements set forth in Resolution 2,689 and CVM Instruction No. 325. With certain limited exceptions, Resolution 2,689 investors are permitted to carry out any type of transaction in the Brazilian financial and capital markets involving a security traded on a stock, futures or organized and authorized over-the-counter market. Investments and remittances outside Brazil of gains, dividends, profits or other payments under our BDRs are made through the exchange markets and are subject to restrictions under foreign investment regulations which generally require, among other things, registration with the Brazilian Central Bank and the CVM. In order to subscribe BDRs through the foreign exchange market, under the Resolution 2,689, an investor residing outside Brazil must:

• appoint at least one representative in Brazil with powers to take actions relating to the investment;

• appoint an authorized custodian in Brazil for the investments, which must be a financial institution duly authorized by the Brazilian Central Bank and the CVM; and

145

• through its representative, register itself as a foreign investor with the CVM and register the investment with the Brazilian Central Bank.

Securities and other financial assets held by foreign investors pursuant to Resolution 2,689 must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Brazilian Central Bank or the CVM. In addition, securities trading by foreign investors is generally restricted to transactions on the Brazilian stock exchanges and organized over-the-counter markets involving securities listed for trading in such markets.

Additionally, an investor operating under the provisions of Resolution 2,689 must be registered with the Brazilian Taxpayers’ Registry, managed by the Brazilian Federal Revenue Office (Receita Federal do Brasil), pursuant to its Instruction No. 568. For information on certain possible Brazilian tax effects on the sale of our BDRs, see “Item 3. Key Information—D. Risk Factors.”

E. Taxation

U.S. Federal Income Tax Considerations

The following is a description of the material U.S. federal income tax consequences of owning and disposing of our common shares. It does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person’s decision to hold the securities. This discussion applies to you only if you are a U.S. Holder (as defined below) that holds our common shares as capital assets for U.S. federal income tax purposes.

This discussion does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986, as amended, or the “Code,” known as the Medicare contribution tax and differing tax consequences applicable to you if you are, for instance:

• a financial institution;

• a regulated investment company;

• a dealer or electing trader in securities that uses a mark-to-market method of tax accounting;

• holding our common shares as part of a “straddle,” integrated transaction or similar transaction;

• a person whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

• a partnership for U.S. federal income tax purposes;

• a tax-exempt entity; or

• a person that owns or is deemed to own 10% or more of our stock (by vote or value);

If you are a partnership for U.S. federal income tax purposes holding our common shares, the U.S. federal income tax treatment of your partners will generally depend on the status of the partners and the activities of your partnership. Partnerships holding our common shares 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 our common shares.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof, any of which is subject to change, possibly with retroactive effect. Please consult your tax adviser concerning the U.S. federal, state and local and non-U.S. tax consequences of owning and disposing of our common shares in your particular circumstances.

146

As used herein, the term “U.S. Holder” means a beneficial owner of our common shares that is, for U.S. federal income tax purposes:

• a citizen or individual 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 or 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.

This discussion generally assumes that we are not, and will not become, a passive foreign investment company, as described below.

Taxation of Distributions

Distributions paid on our common shares, other than certain pro rata distributions of common shares, will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not expect to determine our earnings and profits in accordance with U.S. federal income tax principles, you should expect that a distribution will generally be reported as a dividend. Subject to applicable limitations, dividends paid to certain non-corporate U.S. Holders will be eligible for taxation as “qualified dividend income” and therefore will be taxable at rates applicable to long-term capital gains, provided that certain holding period and other requirements are satisfied. 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 you receive them.

Sale or Other Disposition of Common Shares

For U.S. federal income tax purposes, gain or loss you realize on the sale or other disposition of our common shares will be capital gain or loss, and will be long-term capital gain or loss if you held those shares for more than one year at the time of disposition. The amount of gain or loss will be equal to the difference between your tax basis in the shares disposed of and the amount realized on the disposition. The gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes.

Passive Foreign Investment Company Rules

In general, a non-U.S. corporation will be a “passive foreign investment company,” or “PFIC,” for U.S. federal income tax purposes for any taxable year in which, after applying certain look-through rules, either (1) at least 75% of its gross income is “passive income” or (2) at least 50% of the average quarterly value of its assets consists of assets that produce “passive income” or are held for the production of “passive income.” Passive income for this purpose generally includes dividends, interest, royalties, rents and gains from foreign currency, securities and certain commodities transactions. Based on the current composition of our income and the market value and composition of our assets, we do not believe that we were a PFIC for our taxable year ended December 31, 2017. However, because PFIC status depends upon the composition of our income and assets and the market value of our assets (including, among others, goodwill and less than 25% owned equity investments) from time to time, we cannot assure you that we will not be considered a PFIC for any taxable year.

If we were a PFIC for any taxable year during which you held our common shares, gain recognized by you on a sale or other disposition (including certain pledges) of the common shares would be allocated ratably over your holding period for the common shares. 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 on ordinary income in effect for individuals or corporations, as appropriate for that taxable year, and an interest charge would be imposed on the resulting tax liability. Further, to the extent any distribution in respect of our common shares exceeded 125% of the average of the annual distributions on common shares received by you during the preceding three years or your holding period, whichever was shorter, that distribution would be subject to taxation in the same manner as gain, described immediately above. Certain elections might be available that would result in alternative treatments (such as mark-to-market treatment) of our common shares. You should consult your tax adviser to determine whether these elections would be available and, if so, what the consequences of the alternative treatments would be in your particular circumstances.

147

In addition, if we were a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the favorable tax rates applicable to long-term capital gains discussed above with respect to dividends paid to non-corporate U.S. Holders would not apply.

If a U.S. Holder owns our common shares during any year in which the Company is a PFIC, the U.S. Holder generally must file annual reports containing such information as the U.S. Treasury may require on IRS Form 8621 (or any successor form) with respect to the Company, generally with the U.S. Holder’s federal income tax return for that year.

U.S. Holders should consult their tax advisers regarding the potential application of the PFIC rules.

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 backup withholding unless (1) you are a corporation or other exempt recipient or (2) 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 Internal Revenue Service.

Certain U.S. Holders who are individuals (and under recent Treasury regulations, specified entities that are formed or availed of for purposes of holding certain foreign financial assets) may be required to report information relating to their ownership of an interest in certain foreign financial assets, including stock of a non-U.S. entity, subject to certain exceptions (including an exception for publicly traded stock and interests held in custodial accounts maintained by a U.S. financial institution). U.S. Holders are urged to consult their tax advisers regarding the effect, if any, of this requirement on the ownership and disposition of our common shares.

Bermuda Tax Considerations

The Company has received an assurance from the Ministry of Finance granting an exemption, until March 31, 2035, from the imposition of tax under any applicable Bermuda law computed on profits or income or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, provided that such exemption shall not prevent the application of any such tax or duty to such persons as are ordinarily resident in Bermuda and shall not prevent the application of any tax payable in accordance with the Land Tax Act 1967 or otherwise payable in relation to land in Bermuda leased to the Company.

I. Subsidiary Information

Not applicable.

Item 11. Quantitative and Qualitative Disclosures About Market Risk

Risk Management

We consider market risk to be the potential loss arising from adverse changes in market rates and prices. The company, its subsidiaries and jointly-controlled entities are exposed to market risks, chief of which are: (1) credit risk; (2) liquidity risk; (3) commodities risk; (4) interest rate risk; and (5) foreign currency exchange rate risk. In order to manage its market risks, the Company has adopted policies and procedures which establish limits and monitor risk exposure and counterparties and approve financial instruments. Risk and financial instrument management activities are carried out through the definition of strategies, establishment of control systems and determination of limits to exposure to market risks. We periodically review our exposure to market risks and determine at the senior management level how to manage and reduce the impact of these risks.

The Company uses derivatives solely to manage market risk, especially commodity price and foreign exchange rate fluctuations. Although the value of these hedge instruments varies, these variations are usually offset by the value of the related hedged item. The parties to these agreements are mainly trade boards and trading companies in the case of futures, options and price setting, and major financial institutions in the case of foreign exchange derivatives and interest rate swaps. The company does not use derivatives or other hedge instruments for speculative purposes.

As a result, we do not believe that we are subject to any material credit risk arising from these contracts, and accordingly, we do not anticipate any material credit related losses.

Credit Risk

Credit risk is managed through specific rules concerning client acceptance which require credit rating checks and limits for customer exposure, applicable to all subsidiaries and jointly-controlled entities. Raízen Energia generally requires a letter of credit from a reputable bank for most of our sugar export sales. We do not believe that we are subject to any material credit risk and we do not anticipate any material credit-related losses. Management believes that any credit risk is covered by the allowance for doubtful accounts recorded in our statement of financial position.

Liquidity Risk

Liquidity risk arises where we may encounter difficulties in meeting the obligations associated with our financial liabilities that are settled by delivering cash or another financial asset. Our approach to managing liquidity is to ensure, as far as possible, that we will have sufficient liquidity to meet our liabilities when they are due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to our reputation. Please see note 32 to our audited consolidated financial statements for measures on which our management has been working to enable us to honor our commitments.

Commodities Risk

Mainly applicable to Raízen Energia, agricultural commodity prices and supply levels change according to unpredictable factors such as the weather, investments, government programs and policies and changes in world demand, among others. Raízen conducts sensitivity tests to estimate its exposure to these risks and uses derivatives to mitigate its exposure to sugar price oscillation on the international market. Derivative operations allow the Company to ensure an average margin for future sales. Raízen actively manages its open positions and monitors the result of these activities on a daily basis through effective mark-to-market controls and price impact simulations so that it may adjust targets and strategies due to changes in market conditions.

149

For risk management purposes and to evaluate the overall level of commodity price exposure, Raízen further reduces its exposure to commodity market risk related to the sugar and ethanol produced from sugarcane that is purchased from growers and sugarcane harvested from leased land, as both costs are linked to TSR. The price of sugarcane supplied by growers or the lease payments incurred to produce sugarcane harvested by Raízen from leased land is indexed to the market price of sugar and ethanol, which provides a partial natural hedge to domestic sugar and ethanol sales price exposure.

The table below provides information about the Company’s sugar derivative contracts that are sensitive to changes in commodity prices, specifically sugar prices as of December 31, 2017. For the derivative contracts the table presents the notional amounts in tons, the weighted average contract prices, and the total U.S. dollar contract amount by expected maturity dates.

Interest Rate Risk

We have fixed and floating rate indebtedness and, therefore, we are exposed to market risk as a result of changes in interest rates. See “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Indebtedness” for further information.

Our interest rate risk refers to the impact of an increase in the LIBOR (London Interbank Offered Rate) indexed interest rate, TJLP (Long-term Interest Rate), TR (Reference Interest Rate), IGP-M (General Market Price Index) and CDI (Interbank Deposit Certificate) indexed debt on the Company’s financial results.

150

As of December 31, 2017, 16%, or R$3,469.0 million (9.6%, or R$1,764.8 million as of December 31, 2016) of our consolidated total debt outstanding was fixed rate debt.

The majority of Cosan’s debt, except the jointly-controlled subsidiary Raízen, is dollar-denominated with fixed interest rates or real-denominated debts indexed to the CDI or TJLP. Most of our outstanding debt is linked to the CDI note. We have a substantial amount of marketable securities indexed to the CDI, which provides a partial natural hedge to our interest rate exposure of our real-denominated debts.

Based on the foregoing, we believe that as of December 31, 2017, a hypothetical 10% increase in all interest rates would increase our financial expenses by R$81.1 million per year based on the net financial expenses we recorded in our consolidated statement of profit or loss for the fiscal year ended December 31, 2017.

Foreign Currency Exchange Rate Risk

The foreign exchange variations to which we are exposed are mainly related to our outstanding perpetual notes in an aggregate amount of U.S.$500 million. We use derivatives to hedge the cash flows for payment of part of the interest on this debt against a possible appreciation of U.S. dollar against the real. In addition, basic oil imports for the lubricants business are also exposed to foreign exchange variations, hedged by derivatives on a case-by-case basis.

A significant portion of the revenue of the jointly-controlled subsidiary Raízen Energia is U.S. dollar denominated. Most of Raízen Energia’s costs are denominated in reais and therefore, when the real appreciates against the U.S. dollar, its operating margins are adversely affected. A considerable part of Raízen’s debt is also denominated in dollars exposing it to the risk of variations in the real to U.S. dollar exchange rate (derivative financial instruments are used to hedge the cash flows for payment of interest of these debts).

Raízen Energia has foreign exchange derivatives in order to mitigate its exposure to the effect of foreign exchange variations on its sugar and ethanol export revenues, combined with cash outlays to cover its debt commitments in foreign currency, mainly the U.S. dollar. The exchange rate derivatives together with the sugar price derivatives allow Raízen to ensure an average margin from future sales. Raízen actively manages open positions, and the results of these activities are monitored on a daily basis through effective mark-to-market controls and price impact simulations that allow Raízen to adjust targets and strategies as a result of changes in market conditions. Raízen uses financial derivative instruments to hedge foreign exchange risk.

At December 31, 2017, our foreign exchange exposure, net was R$1,083 million (R$495.0 million in the fiscal year ended December 31, 2016) which were represented by forward, future, swap and put option contracts as disclosed in note 32 of our consolidated financial statements.

As a measure of our market risk with respect to our foreign currency exposure, a hypothetical 10% appreciation of the real against the U.S. dollar would increase our export sales by R$638 million per year, based on the level of our total export sales for the fiscal year ended December 31, 2017, before considering the effects on U.S. dollar derivative contracts and other dollar denominated assets and liabilities, as set forth below:

U.S. dollar financial instruments outstanding at December 31, 2017:	Notional amount/ Quantity			Estimated Fair value Asset (Liability)			Foreign Exchange Gain/ Loss – 10% FX rate Increase
	(in thousands of reais)
Denominated debt		8,919,712			8,919,712			891,971
Denominated receivables		(25,797	)		(25,797	)		(2,580	)
Foreign exchange exposure, net		1,082,946			1,082,946			108,295

None.

Item 15. Controls and Procedures

(a) Disclosure Controls and Procedures

As of December 31, 2017, under management’s supervision and with its participation, including that of our Chief Executive Officer and Chief Financial Officer, we performed an evaluation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934).

Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2017 to ensure that information required to be disclosed under the Exchange Act is recorded, authorized, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, and the information required to be disclosed is accumulated and communicated, in order to allow timely decisions regarding required disclosure.

(b) 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 Rule 13a-15(f) under the Securities Act of 1934. Management conducted an assessment of the effectiveness of internal control over financial reporting based on recommendations and correlated layers established in the Internal Controls Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, or “COSO 2013.” Based on this assessment and those criteria, management concluded that internal control over financial reporting was effective as of December 31, 2017.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 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.

(c) Attestation Report of the Registered Public Accounting Firm

The effectiveness of the internal control over financial reporting, as of December 31, 2017, has been audited by KPMG, an independent registered public accounting firm, whose attestation report on such matter appears on page F-3 of our audited financial statements.

(d) Changes in Internal Control over Financial Reporting

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.

Management’s  Annual  Report  on Internal Control over Financial Reporting

The management of Cosan Limited (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting for the Company.

The 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. The 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. Therefore even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of the changes in conditions.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, based on the criteria set forth in Internal Control - Integrated Framework 2013 issued by the Committee of Sponsoring Organization of the Treadway Commission (COSO). Based on that assessment management has concluded that as of December 31, 2017, the Company’s internal control over financial reporting is effective.

Management assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017 has been audited by KPMG Auditores Independentes, the Company’s independent registered public accounting firm, as stated in their report which appears herein.

To the Shareholders and the Board of Directors

Cosan Limited:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Cosan Limited and subsidiaries (the Company) as of December 31, 2017 and 2016, the related consolidated statements of profit or loss and other comprehensive income, changes in equity and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, 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 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB). 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 Committee of Sponsoring Organizations of the Treadway Commission.

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 the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion 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.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

2 Basis of preparation

2.1 Statement of compliance

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

The relevant information of the financial statements, and only them, are being evidenced and correspond to those used by management in its management.

These consolidated financial statements were authorized for issue by the Board of Directors on February 22, 2018.

Certain amounts of the comparative balances, in the statements of profit or loss, statements of cash flows and in the notes 9, 11, 12, 13, 17, 18, 20, 22, 23 and 31, were reclassified to improve the level of details of disclosures in the financial statements. These reclassifications had inconsequential impacts on the Company´s financial statements.

2.2 Functional and presentation currency

The consolidated financial statements are presented in Brazilian Reais. However, the functional currency of Cosan Limited is the U.S. Dollar (U.S.$). The Brazilian Real is the functional currency of Cosan S.A., Cosan Logística, its subsidiaries and joint ventures, located in Brazil, as it is the currency of the primary economic environment in which they operate, generate and expend cash. The main functional currency for the subsidiaries located outside Brazil is U.S. Dollar or the Pound Sterling (GBP).

2.3 Use of judgments and estimates

The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue and expenses at the end of the reporting period. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized prospectively. Information about critical judgments, assumptions and estimation uncertainties in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes:

• Notes 15 and 16 – Property, plant and equipment and intangible assets

The Company performs annually a review of impairment indicators for intangible assets with defined useful lives and property, plant and equipment. Also, an impairment test is undertaken for goodwill and intangible assets with indefinite useful lives. Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs to sell and its value in use. The key assumptions used to determine the recoverable amount of the different cash generating units to which goodwill is allocated are explained in note 16.

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

The subsidiary Comgás has an agreement for the public concession of gas distribution service which the Conceding Authority controls what services must be rendered and what prices will be applied, as well as included significant interest in the infrastructure at the end of the concession. This concession agreement represents the right to charge customers for the supply of gas during the effective period of the agreement. Therefore, the Company recognizes this right as intangible assets.

Thus, the infrastructure construction necessary for gas distribution is considered a service to the Grantor and the related revenue is recognized at fair value. Financing costs directly related to construction are also capitalized.

The Company does not recognize a margin on the infrastructure construction.

Subject to approval of the Granting Authority, the Company may request only once the extension of the distribution services for another 20 years. When the concession is terminated, the assets linked to the rendering of gas distribution services will be returned to the Granting Authority, and the Company will be entitled to receive an indemnity to be determined based on assessments and evaluations to be calculated at the time. Currently the figures for compensation are not predetermined or determinable, which is why the Company did not apply the bifurcated model for the accounting of financial assets.

The amortization of intangible assets reflects the pattern expected for the utilization of the future economic benefits by the Company, which corresponds to the useful lives of the assets comprising the infrastructure consonant to the São Paulo State Sanitation and Energy Regulatory Agency (“ARSESP”) provisions, as disclosed in note 16.

The amortization of the intangible assets is discontinued when the related asset is fully used or written off, and no longer is included in the calculation basis of the tariff for the rendering of the concession services, whichever occurs first.

The subsidiary Rumo has a concession rights generated in the business combination of ALL, which was fully allocated to Rumo Malha Norte concession and amortized on the straight-line method based on estimated useful lives of intangible assets, from the date on which these are available for use.

• Note 18 – Operating lease commitments

The Company contracted commercial leases of locomotives and wagons. The classification of the lease as operational or financial is determined based on an evaluation of the terms and conditions of the contracts. The Company identified the cases in which it assumes substantially all the risks and benefits of ownership of the said assets, recording such cases as a financial lease.

• Note 23 – Income taxes and social contribution

A deferred tax asset is recognized for loss carryforwards to the extent that it is probable that future taxable income will be generated to realize such losses. Significant judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the timing and the level of future taxable income together with future tax planning strategies.

• Other non-current assets

The subsidiary Comgás has natural gas supply contracts with specific characteristics, such as minimum withdrawal obligations by the Comgás (take or pay for commodity and ship or pay for transportation), that is, if Comgás consumes below contractual obligations, it must make payment of the differences between the volume consumed and the minimum contracted volumes, and may compensate them (through consumption) over the period of validity of the respective contract, provided that consumption exceeds the contracted minimum quantity. In addition, the supplier allows in contractual clause that there is recovery of the volume eventually accumulated for the term of 365 days after the termination of the contracts.

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

Therefore, it is currently forecast to recover all the cumulative volume since, during the recovery period provided for in the agreement, there will be no new accumulation related to the minimum commitments contracted for this period. Given the recoverable nature of this inventory, the amounts paid and not used were recognized in assets under “Paid and unused transportation.”

• Note 32 – Fair value of derivatives and other financial instruments

When the fair value of financial assets and liabilities cannot be derived from active markets, their fair value is determined using valuation techniques including the discounted cash flow model. The inputs to these models are taken from observable markets where possible, but when this is not feasible, a degree of judgment is required in determining fair values. Judgment is required in the determination of inputs such as liquidity risk, credit risk and volatility. Changes in these variables could affect the reported fair value of financial instruments.

• Note 33 – Post-employment benefits

The cost of defined benefit pension plans and other post-employment and the present value of the pension obligation is determined using actuarial valuations. An actuarial valuation involves the use of various assumptions which may differ from actual results in the future. These include the determination of the discount rate, future salary increases, mortality rates and future pension increases. A defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed by management at each reporting date.

• Note 34 – Share-based payments

The Company measures employees’ share-based compensation cost by referencing the fair value of the shares at the grant date. The estimation of fair value for share-based payment transactions requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the plan. This estimate also requires determining the most appropriate inputs to the valuation model including the assumption of the expected life of the stock option or stock grant, volatility and dividend yield. The assumptions and models used for estimating fair value for share-based payment transactions are disclosed in Note 34.

• Note 24 – Provisions for legal proceedings

Provisions for legal proceedings are recognized as other expenses when the Company has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated.

The assessment of probability loss includes the available evidence, hierarchy of laws, jurisprudence, the most recent court decisions and relevance in the legal system, as well as the opinion of outside counsel. Provisions are reviewed and adjusted according to circumstances, such as limitation period, conclusions of tax inspections or additional exposures identified based on new matters or court decisions.

Provisions for legal proceedings resulting from business combinations are estimated at fair value.

• Note 14—Investment in joint ventures

The Company has a 50% interest in a joint agreement. The joint venture agreements require unanimous consent from all parties for all relevant activities.

The two partners have direct rights to the assets of the partnership and are jointly and severally liable for the liabilities incurred by the partnership. This entity is therefore classified as a joint ventures and the Company recognizes its interest in the joint ventures using the equity method as described in Note 14.

Measurement of fair value

A number of the Company’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities.

The Company regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the valuation team assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of the accounting practices adopted in Brazil and the international standards IFRS, including the level in the fair value hierarchy in which such valuations should be classified.

When measuring the fair value of an asset or a liability, the Company uses observable market data when available. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:

• Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

• Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Company recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

2.4 Basis of measurement

The consolidated financial statements have been prepared on the historical cost basis except for the following material items in the consolidated statement of financial position:

• financial instruments at fair value through profit or loss;

• derivative financial instruments at fair value through profit or loss;

• loans measured at fair value through profit or loss;

• available-for-sale financial assets are measured at fair value;

• contingent consideration assumed in a business combination;

• employee’s defined benefit obligations are presented at the present value of the actuarial obligation net of the fair value of plan assets (Note 33).

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

(a) Business combinations

Business combinations are accounted for using the acquisition method. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired and liabilities assumed. Any goodwill that arises is tested annually for impairment. Transaction costs are expensed as incurred, except if related to the issue of debt or equity.

The consideration transferred does not include amounts related to the settlement of pre-existing relationships. Such amounts are generally recognized in profit or loss.

(b) Non-controlling interests

For each business combination, the Company elects to measure any non-controlling interests in the acquisition either:

• at fair value; or

• at their proportionate share of the acquirer’s identifiable net assets, which are generally at fair value.

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions – that is, as transactions with the owners in their capacity as owners.

(c) Subsidiaries

Subsidiaries are all entities over which the Company has control. Subsidiaries are fully consolidated from the date of acquisition of control, and continue to be consolidated until the date that control ceases to exist. They are deconsolidated from the date that control ceases.

The financial statements of subsidiaries are prepared for the same reporting period as that of the parent company, using consistent accounting policies.

(d) Investments in associates (equity method investees)

Associates are those entities in which the Company has significant influence, but not control or joint control, over the financial and operating policies.

Investments in associates are accounted for under the equity method and are recognized initially at cost. The cost of the investment includes transaction costs.

Under the equity method of accounting, the share attributable to the Company of the profit or loss for the period of such investments is accounted for in the statement of profit or loss, in “Equity in investees.” Unrealized gains and losses arising on transactions between the Company and the investees are eliminated based on the percentage of interest held in such investees. The other comprehensive income of subsidiaries, associates and jointly controlled entities is recorded directly in the Company’s shareholders’ equity, in “Other comprehensive income.”

F-22

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

(e) Investments in joint ventures (equity method investees)

The Company has interests in joint ventures, in which contractual arrangement establishes joint control over the voting and economic activities of the entity. The contractual arrangements require unanimous agreement for financial and operating decisions among the ventures. The Company recognizes its interest in the joint ventures using the equity method (Note 14).

(f) Transactions eliminated on consolidation

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements.

Unrealized gains arising from transactions with equity accounted investees are eliminated against the investment to the extent of the Company’s interest in the investee. Unrealized losses are similarly eliminated, but only to the extent that there is no evidence of impairment.

3.2 Foreign currency

a) Foreign currency transactions

Transactions in foreign currencies are translated to the respective functional currencies of each subsidiary using the exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are translated to the functional currency using the exchange rate at the reporting date.

b) Foreign operations

The assets and liabilities derived from foreign operations, including goodwill and fair value adjustments arising on acquisition, are translated to Brazilian Reais using the exchange rates at the reporting date. Income and expenses of foreign operations are translated to Brazilian Reais using the exchange rates at the dates of the transactions.

Foreign currency differences are recognized in other comprehensive income, and presented in the foreign currency translation reserve (translation reserve) in equity. However, if the foreign operation is a non-wholly owned subsidiary, then the relevant proportion of the translation difference is allocated to non-controlling interests. When a foreign operation is disposed of such that control, significant influence or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal.

c) Translation of subsidiaries and associates’ financial statements

These consolidated financial statements have been translated to the Brazilian Real using the following criteria:

(a) assets and liabilities have been translated using the exchange rate at the balance sheet date;

(b) statement of profit or loss, comprehensive income and statement of cash flows have been translated using the monthly average exchange rate; and

(c) shareholders’ equity has been translated using the historical exchange rate.

F-23

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

Translation effects have been recognized in shareholders’ equity in “Cumulative translation adjustment.”

The consolidated financial statements of each subsidiary included in these consolidated financial statements and equity method investments are prepared based on their respective functional currencies. For subsidiaries whose functional currency is a currency other than the Brazilian Real, asset and liability accounts are translated into the Company’s reporting currency using exchange rates in effect at the date of the statement of financial position, and income and expense items are translated using monthly average exchange rates and shareholders’ equity has been translated using the historical exchange rate. The resulting translation adjustments are reported in a separate component of shareholders’ equity, as cumulative translation adjustment.

The exchange rate of the Brazilian Real (R$) to the U.S. Dollar (U.S.$) was R$ 3.3080 at December 31, 2017, R$ 3.2591 at December 31, 2016 and R$ 3.9048 at December 31, 2015.

3.3 Financial instruments

(i) Non-derivative financial assets

The Company initially recognizes loans and receivables on the date that they are originated. All other financial assets (including assets designated as at fair value through profit or loss) are recognized initially on the trade date, which is the date that the Company becomes a party to the contractual provisions of the instrument.

The Company classifies non-derivative financial assets into the following categories: financial assets at fair value through profit or loss, held-to-maturity financial assets, loans and receivables.

a) Financial assets at fair value through profit or loss

A financial asset is classified at fair value through profit or loss if it is classified as held-for-trading or is designated as such on initial recognition. Financial assets are designated at fair value through profit or loss if the Company manages such investments and makes purchase and sale decisions based on their fair value in accordance with the Company’s documented risk management or investment strategy. Attributable transaction costs are recognized in profit or loss as incurred. Financial assets at fair value through profit or loss are measured at fair value and changes therein, which takes into account any dividend income, are recognized in profit or loss.

i. Marketable securities

Investments in securities with a maturity date greater than three months at the date of purchase and other securities for which there is more than an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal

F-24

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

b) Loans and receivables

Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Such assets are recognized initially at fair value plus any directly attributable transaction costs. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method, less any impairment losses.

Loans and receivables comprise cash and cash equivalents, restricted cash , trade and other receivables.

Cash and cash equivalents

Cash and cash equivalents comprise cash balances, call deposits and highly liquid short-term investments with maturities of three months or less from the acquisition date that are subject to an insignificant risk of changes in their fair value, and are used by the Company in the management of its short-term commitments.

c) Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial assets that are designated as available-for-sale or are not classified in any of the above categories of financial assets. Available-for-sale financial assets are recognized initially at fair value plus any directly attributable transaction costs.

Subsequent to initial recognition, the financial assets are measured at fair value and changes therein, other than impairment losses and foreign currency gain/losses on available-for-sale debt instruments, are recognized in other comprehensive income and presented in the consolidated statements of changes in equity. When an investment is derecognized, the gain or loss accumulated in equity is reclassified to profit or loss.

Derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when:

• The rights to receive cash flows from the asset have expired; or

• 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 (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

F-25

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and, to what extent, it has retained the risks and rewards of ownership.

When it has neither transferred nor retained substantially all of the risks and rewards of the asset nor transferred control of it, the asset is recognized to the extent of the Company’s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

(ii) Non-derivative financial liabilities

The Company initially recognizes debt securities issued and subordinated liabilities on the date that they are originated. All other financial liabilities are recognized initially on the trade date, which is the date that the Company becomes a party to the contractual provisions of the instrument.

The Company derecognizes a financial liability when its contractual obligations are discharged, cancelled or expire.

The Company classifies non-derivative financial liabilities, except contingent consideration, as other financial liabilities. Such financial liabilities are initially recognized at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these financial liabilities are measured at amortized cost using the effective interest method.

Financial liabilities comprise loans and borrowings, debt securities issued, bank overdrafts, and trade and other payables.

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires.

When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the statement of profit or loss.

(iii) Share capital

Ordinary shares

Incremental costs directly attributable to the issue of ordinary shares are recognized as a deduction from equity. Income taxes relating to transaction costs of an equity transaction are accounted for in accordance with IAS 12.

Preference shares

Non-redeemable preference shares are classified as equity, because they bear discretionary dividends, do not contain any obligations to deliver cash or other financial assets and do not require settlement in a variable number of the Company’s equity instruments. Discretionary dividends thereon are recognized as equity distributions on approval by the Company’s shareholders.

F-26

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

Mandatory minimum dividends as defined in the bylaws are recognized as liabilities.

(iv) Derivative financial instruments, including hedge accounting

The Company holds derivative financial instruments to hedge its foreign currency and interest rate risk exposures. Embedded derivatives are separated from the host contract and accounted for separately if:

(a) The economic characteristics and risks of the host contract and the embedded derivative are not closely related;

(b) A separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

(c) The combined instrument is not measured at fair value through profit or loss.

On initial designation of the derivative as a hedging instrument, the Company formally documents the relationship between the hedging instrument and hedged item, including the risk management objectives and strategy in undertaking the hedge transaction and the hedged risk, together with the methods that will be used to assess the effectiveness of the hedging relationship. The Company makes an assessment, both at the inception of the hedge relationship as well as on an ongoing basis, of whether the hedging instruments are expected to be highly effective in offsetting the changes in the fair value or cash flows of the respective hedged items attributable to the hedged risk, and whether the actual results of each hedge are within a range of 80% – 125%. For a cash flow hedge of a forecast transaction, the transaction should be highly probable to occur and should present an exposure to variations in cash flows that ultimately could affect reported profit or loss.

Derivatives are initially recognized at fair value; any attributable transaction costs are recognized in profit or loss as incurred. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are accounted for as described below:

• Cash flow hedges

When a derivative is designated as the hedging instrument in a hedge of the variability in cash flows attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction that could affect profit or loss, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income and presented in the hedging reserve in equity. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss.

When the hedged item is a non-financial asset, the amount accumulated in equity is retained in other comprehensive income and reclassified to profit or loss in the same period or periods during which the non-financial item affects profit or loss. If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated or exercised, or the designation is revoked, then hedge accounting is discontinued prospectively. If the forecast transaction is no longer expected to occur, then the balance in equity is reclassified to profit or loss.

F-27

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

• Fair value hedge

Changes in fair value of derivatives, that are designated and qualify as fair value hedge, are recorded in the statement of profit or loss, with any changes in fair value of the hedged asset or liability that are attributable to the hedged risk. The Company applies hedge accounting for fair value hedges to protect itself against the risk of changes in interest rates and foreign exchange rates on loans. The gain or loss related to the effective portion of interest rate swaps to protect against fixed rate borrowings is recognized in the statement of profit and loss as “Financial expenses.” The gain or loss related to the ineffective portion is recognized in the statement of profit or loss as “Other gains (losses), net.” Changes in fair value of fixed rate borrowings hedged attributable to interest rate risk are recognized in the statement of profit or loss as “Financial expenses.”

If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the method of effective interest rate is used, is amortized to income over the period to maturity.

• Embedded derivatives

Changes in the fair value of separated embedded derivatives are recognized immediately in profit or loss.

• Other derivative financial instruments

When a derivative financial instrument is not designated in a hedge relationship and does not qualify for hedge accounting, all changes in its fair value are recognized immediately in profit or loss.

3.4 Inventory

Inventory is recorded at the lower of average cost of acquisition or production and net realizable value, whichever the less.

Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

Provisions for slow-moving or obsolete inventory are recorded when deemed necessary by management. The cost of finished goods and work in progress comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). It excludes borrowing costs.

3.5 Property, plant and equipment

(a) Recognition and measurement

Items of property, plant and equipment are measured at cost less accumulated depreciation and any accumulated impairment losses.

F-28

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

Cost includes expenditures that are directly attributable to the acquisition of the asset. The cost of constructed assets includes:

• the cost of materials and direct labor;

• any other costs directly attributable to bringing the assets to a working condition for their intended use;

• an estimate of the costs of dismantling and removing the items and restoring the site on which they are located, when the Company has an obligation to remove the asset or restore the site; and

• capitalized borrowing costs.

Cost also includes transfers from equity of any gain or loss on qualifying cash flow hedges of foreign currency purchases of property, plant and equipment. Purchased software that is integral to the functionality of the related equipment is capitalized as part of that equipment.

When components of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

Any gain or loss on disposal of an item of property, plant and equipment, calculated as the difference between the net proceeds from disposal and the carrying amount of the item, is recognized in profit or loss.

(i) Reclassification to investment property

When the use of a property changes from held to use to investment property, the property is remeasured at fair value and reclassified as investment property. Any gain or loss arising on this remeasurement is recognized in equity.

(ii) Subsequent costs

Subsequent expenditure is capitalized only when it is probable that the future economic benefits associated with the expenditure will flow to the Company. Ongoing repairs and maintenance are expensed as incurred.

(iii) Depreciation

Items of property, plant and equipment are depreciated from the date they are available for use or, in respect of constructed assets, from the date that the asset is completed and ready for use.

Depreciation is calculated on the carrying value of property, plant and equipment less their estimated residual values using the straight-line basis over their estimated useful lives. Depreciation is generally recognized in profit or loss, unless it is capitalized as part of the cost of another asset. Assets recognized under finance leases are depreciated over the shorter of the lease term and their useful lives unless it is reasonably certain that the Company will obtain ownership by the end of the lease term. Land is not depreciated.

F-29

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets as follows:

Buildings and improvements	4% to 5%
Machinery, equipment and facilities	8% to 11%
Airplanes, vessels and vehicles	10% to 20%
Railcars	2.9% to 6%
Locomotives	3.33% to 8%
Permanent railways	4%
Furniture and fixtures	10% to 15%
Computer equipment	20%

Costs of normal periodic maintenance are recorded as expenses when incurred when the components will not improve the production capacity or introduce improvements to the equipment.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed annually and adjusted prospectively. During the fiscal year ended December 31, 2017, the subsidiary Rumo S.A. conducted a useful life review of a group of approximately 200 locomotives allocated to the logistics segment. Locomotives comprise individual components with different useful lives, and the review resulted in a reduction of useful lives of some components to reflect the time that the subsidiary Rumo intends to use those components through its economic life. The new useful life was applied starting from January 1^st 2017.

Depreciation methods such as useful lives and residual values are reviewed at each year-end, or when there is significant change without an expected consumption pattern, such as relevant incident and technical obsolescence. Any adjustments are recognized as changes in accounting estimates, if appropriate.

3.6 Intangible assets and goodwill

(a) Goodwill

Goodwill is measured at cost less accumulated impairment losses. With respect to equity method investees, the carrying amount of goodwill is included in the carrying amount of the investment, and any impairment loss is allocated to the carrying amount of the equity method investee as a whole.

(b) Other intangible assets

Other intangible assets that are acquired by the Company and have a finite life are measured at cost less accumulated amortization and any accumulated impairment losses.

(c) Subsequent expenditure

Subsequent expenditures are capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditures are recognized in profit or loss as incurred.

(d) Amortization

Except for goodwill, intangible assets are amortized on a straight-line basis over their estimated useful lives, from the date that they are available for use or acquired.

Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(e) Contracts with customers

Costs incurred on development of gas systems for new clients (including pipelines, valves, and general equipment) are recognized as intangible assets and amortized over the contract period.

F-30

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

(f) Intangible assets related to the concession rights agreement

The Company has a public concession agreement for a gas distribution service in which the Concession Authority controls what services will be provided and the price, as well it holds a significant participation in the infrastructure at the end of the concession. This concession agreement represents the right to charge users for gas supply during the term of the agreement. Accordingly, the Company recognizes this right as an intangible asset

The intangible asset comprises: (i) the concession right recognized upon the business combination of Comgás, which is being amortized over the concession period on a straight line basis, considering the extension of the distribution services for another 20 years; and (ii) the acquired or constructed assets underlying the concession necessary for the distribution of gas, which is being depreciated to match the period over which the future economic benefits of the asset are expected to accrue to the Company, or the final term of the concession, whatever occurs first. This period reflects the economic useful lives of each of the underlying assets that comprise the concession. This economic useful life is also used by the regulator, The Natural Gas Agency of the State of São Paulo, to determine the basis for measuring the tariff for rendering the services under the concession.

The concession agreement was signed on May 31, 1999 with an initial term of 30 years. Subject to approval of the Conceding Authority, the Company may request only once the extension of the distribution services for another 20 years. When the concession is terminated, the assets linked to the rendering of gas distribution services will be returned to the Conceding Authority, and the Company will be entitled to receive an indemnity to be determined based on assessments and evaluations considering the book values to be calculated at the time.

The concession contract determines that the tariff charged by Comgás be reviewed annually, in May, with the aim to realign the tariff charged to consumers to the cost of the gas and adjust for inflation.

Once the concession is terminated, the Company has the right to request the reversion to the Granting Authority of the assets and facilities linked to the gas distribution service. Currently, the amounts related to indemnification are not pre-established or determinable, that’s why the Company did not apply the bifurcated model for the accounting of the financial asset.

Concession rights generated in the business combination of ALL was fully allocated to the Rumo Malha Norte concession and amortized on a straight-line basis.

3.7 Impairment

(i) Non-derivative financial assets

A financial asset not classified as at fair value through profit or loss, including an interest in an equity-accounted investee, is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset, and that loss event(s) had an impact on the estimated future cash flows of that asset that can be estimated reliably.

F-31

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

(a) Financial assets measured at amortized cost

An impairment loss in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset’s original effective interest rate. Losses are recognized in profit or loss and reflected in an allowance account against loans and receivables or held-to-maturity investment securities. If, in a subsequent period, the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the statement of profit or loss.

(b) Available-for-sale financial assets

Impairment losses on available-for-sale financial assets are recognized by reclassifying the accumulated losses recorded in equity to profit or loss. The cumulative loss that is reclassified from equity to profit or loss is the difference between the acquisition cost, net of any principal repayment and amortization, and the current fair value, less any impairment loss recognized previously in profit or loss.

(ii) Non-financial assets

The carrying amounts of the Company’s non-financial assets, except investment property, inventories and deferred tax assets, are reviewed at each reporting date to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill is tested annually for impairment. An impairment loss is recognized if the carrying amount of an asset or cash-generating unit (“CGU”) exceeds its recoverable amount.

The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU. For impairment testing, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or CGUs. Subject to an operating segment ceiling test, CGUs to which goodwill has been allocated are aggregated so that the level at which impairment testing is performed reflects the lowest level at which goodwill is monitored for internal reporting purposes. Goodwill acquired in a business combination is allocated to Companies of CGUs that are expected to benefit from the synergies of the combination.

Impairment losses are recognized in profit or loss. Impairment losses recognized for CGUs are allocated first to reduce the carrying amount of any goodwill allocated to the CGU (group of CGUs), and then to reduce the carrying amounts of the other assets in the CGU (group of CGUs) on a pro rata basis.

An impairment loss with respect to goodwill is not reversed. For other assets, an impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

3.8 Provisions

A provision is recognized if, as a result of a past event, the Company has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

3.9 Employee benefits

• Short-term employee benefits

Short-term employee benefit obligations are measured on an undiscounted basis and are expensed when the related service is provided. A liability is recognized for the amount expected to be paid under short-term cash bonus or profit-sharing plans if the Company has a present legal or constructive obligation to pay these amounts as a result of past services provided by the employee, and the obligation can be estimated reliably.

• Share-based payment transactions

The grant-date fair value of share-based payment awards granted to employees is recognized as an employee compensation expense, with a corresponding increase in equity, over the period that the employees become unconditionally entitled to the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market performance conditions are expected to be met, such that the amount ultimately recognized as an expense is based on the number of awards that meet the related service and non-market performance conditions at the vesting date. For share-based payment awards with non-vesting conditions, the grant-date fair value of the share-based payment is measured to reflect such conditions and there is no true-up for differences between expected and actual outcomes.

The fair value of the amount payable to employees with respect to share appreciation rights, which are settled in cash, is recognized as an expense with a corresponding increase in liabilities, over the period that the employees become unconditionally entitled to the cash payment. The liability is remeasured at each reporting date and at settlement date based on the fair value of the share appreciation rights. Any changes in the liability are recognized as employee benefit expenses in profit or loss.

F-33

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

The accounting for modification on plans depends on whether the modification changes the classification of the arrangement and whether the changes are beneficial to the counterparty.

If a modification increases the number of equity instruments granted, then the entity recognizes the fair value of the additional equity instruments measured at the date of modification. The additional share-based payment cost is attributed over the period from the date of modification to the end of the vesting period of the additional equity instruments.

Cancellations or settlements of equity-settled share-based payments during the vesting period by the entity or by the counterparty are accounted for as accelerated vesting; therefore, the amount that would otherwise have been recognized for services received is recognized immediately.

• Defined contribution plans

A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions into a separate entity and has no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution plans are recognized as an employee benefit expense in profit or loss in the periods during which related services are rendered by employees. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in future payments is available. Contributions to a defined contribution plan that is due more than 12 months after the end of the period in which the employees render the service are discounted to their present value.

• Defined benefit plans

The Company is the sponsor of defined benefit pension plans for some of its employees. A defined benefit plan is a post-employment benefit plans other than a defined contribution plan.

The liability recognized in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method.

The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows, using interest rates that are denominated in the currency in which the benefits will be paid, and that have terms approximating to the terms of the related obligation.

Gains and losses arising from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur, directly in other comprehensive income.

Changes in the present value of the defined benefit obligation resulting from plan amendments or curtailments are recognized immediately in profit or loss as past service costs.

Some of the Company’s pension plan, even though it is substantially defined contribution, has a variable component, whose risk is linked to the payment of minimum benefit and to the increase of the future contributions of the sponsors in the benefits in the event of Death Tax of the active taxpayer as well as in Disability Retirement, limited to three salaries. Any actuarial liability calculated, is recorded by the Company.

• Other long-term employee benefit

The Company’s net obligation in respect of long-term employee benefits other than pension plans is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value, and the fair value of any related assets is deducted. The discount rate is the yield at the reporting date of the financial statements for the high credit quality bonds, and maturity dates approximating the terms of the Company’s obligations and that are denominated in the currency in which the benefits are expected to be paid. The calculation is performed using the projected unit credit method. Any actuarial gains and losses are recognized in profit or loss in the period in which they arise.

3.10 Revenue

(a) Sales of goods

Revenue from the sale of goods, in the ordinary course of business, is measured at the fair value of the consideration received or receivable, net of returns, trade discounts and volume rebates. Revenue is recognized when significant risks and rewards of ownership have been transferred to the customer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably. If it is probable that discounts will be granted and the amount can be measured reliably, then the discount is recognized as a reduction of revenue as the sales are recognized.

(b) Services rendered

Revenues from services are recognized when the amount of revenue can be measured reliably, when it is probable that the economic benefits associated with the transaction will flow to the Company, when the stage of completion of the transaction at the end of the reporting period can be measured reliably, as well as when its amount and related costs can be measured reliably. Service prices are established based on service orders or contracts. Services for which payment is made in advance are recorded as deferred revenue in other liabilities and recognized in revenue when the services are rendered.

The Company revenue recognizes revenue as follows:

• Billed revenue

Revenue from gas distribution services is recognized when its amount can be reliably measured, and is recognized in profit or loss when the volumes are delivered to customers.

• Unbilled revenue

Unbilled gas refers to the portion of gas supplied for which metering and billing to customers have not yet occurred. This amount is estimated based on the period between measurement and the last day of the month.

The actual volume billed may be different from estimates. The Company believes that, based on its historical experience with similar operation, the unbilled estimated amount will not significantly differ from actual amounts.

• Concession construction revenue

The construction of the infrastructure necessary for gas distribution is considered a construction service rendered to the Conceding Authority, and the related income is recognized in profit or loss at finishing stage of the work.

Construction costs are recognized by reference to the stage of completion of the construction activity at the end of the reporting period, and are included in cost of sales.

(c) Deferred revenue

The Company´s deferred revenue consists in advances received from clients seeking investment in fixed assets in return for a rail service contract requiring future performance of services by the Company.

3.11 Government grants

Government grants are recognized where there is reasonable assurance that the grant will be received and all attached conditions will be complied with. The indirect subsidiary Rumo Malha Norte has a fiscal incentive whose benefit includes a reduction of 75% on income tax based on operation profit beginning in 2008 until 2024.

3.12 Leases

The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at the inception date.

a) Leased assets

Leases of property, plant and equipment that transfer to the Company substantially all of the risks and rewards of ownership are classified as finance leases. The leased assets are measured initially at an amount equal to the lower of their fair value and the present value of the minimum lease payments. Subsequent to initial recognition, the assets are accounted for in accordance with the accounting policy applicable to that asset.

A leased asset is depreciated over the useful life of the asset. However, if there is no reasonable certainty that the Company will obtain ownership by the end of the lease term, the asset is depreciated over the shorter of the estimated useful life of the asset and the lease term.

Assets held under other leases are classified as operating leases and are not recognized in the Company’s statement of financial position.

b) Lease payments

Payments made under operating leases are recognized in profit or loss on a straight-line basis over the term of the lease. Lease incentives received are recognized as an integral part of the total lease expense, over the term of the lease.

Minimum lease payments made under finance leases are apportioned between the finance expense and the reduction of the outstanding liability. The finance expense is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability.

The amounts paid in advance by the Company are recorded as assets and allocated in income linearly during the term of the contract. The expenses incurred during the grace period are recorded in income and maintained as payables, being written off in proportion to the payment of current installments.

3.13 Finance income and finance expense

Finance income comprises interest income on funds invested (including available-for-sale financial assets), dividend income, gains on the disposal of available-for-sale financial assets, fair value gains on financial assets at fair value through profit or loss, gains on the remeasurement to fair value of any pre-existing interest in an acquire in a business combination, gains on hedging instruments that are recognized in profit or loss and reclassifications of net gains previously recognized in other comprehensive income. Interest income is recognized as it accrues in profit or loss, using the effective interest method. Dividend income is recognized in profit or loss on the date that the Company’s right to receive payment is established, which in the case of quoted securities is normally the ex-dividend date.

Finance expense comprise interest expense on borrowings, unwinding of the discount on provisions and deferred consideration, losses on disposal of available-for-sale financial assets, dividends on preference shares classified as liabilities, fair value losses on financial assets at fair value through profit or loss and contingent consideration, impairment losses recognized on financial assets (other than trade receivables), losses on hedging instruments that are recognized in profit or loss and reclassifications of net losses previously recognized in other comprehensive income.

Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are recognized in profit or loss using the effective interest method.

Foreign currency gains and losses on financial assets and financial liabilities are reported on a net basis as either finance income or finance cost depending on whether the net foreign currency fluctuations result in a gain or loss position.

3.14 Taxes

Income taxes are comprised of income tax and social contribution at a combined rate of 34%. Tax expense comprises current and deferred tax. Current tax and deferred tax is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income.

Certain subsidiaries measure income tax and social contribution due under the Brazilian presumed profits regime. The presumed profit came up from a percentage of 32% of operating revenues. Under the aforementioned regime the applicable tax rate is for income tax is 15% over the presumed profit, plus an additional 10% when operating revenues exceed of R$ 240, and 9% over the presumed profit for social contribution.

a) Current tax

Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years.

b) Deferred tax

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes and tax loss. Deferred tax is not recognized for:

• temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss;

• temporary differences related to investments in subsidiaries, associates and joint ventures to the extent that the Company is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and

• taxable temporary differences arising on the initial recognition of goodwill.

The measurement of deferred tax reflects the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. For investment property that is measured at fair value, the presumption that the carrying amount of the investment property will be recovered through sale has not been rebutted.

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realized simultaneously.

A deferred tax asset is recognized for loss carryforwards, tax credits and deductible temporary differences to the extent that it is probable that future taxable income will be generated in the future. Deferred tax assets are reviewed at each reporting date and written off to the extent that it is no longer probable that the related tax benefit will be realized.

c) Sales taxes

Net revenue is recognized net of discounts and sales taxes.

(In thousands of Brazilian Reais – R$, unless otherwise stated)

d) Tax exposures

In determining the amount of current and deferred tax, the Company takes into account the impact of uncertain tax positions and whether additional taxes and interest may be due. This assessment relies on estimates and assumptions and may involve a series of judgments about future events. New information may become available that causes the Company to change its judgment regarding the adequacy of existing tax liabilities; such changes to tax liabilities will impact tax expense in the period that such a determination is made.

3.15 Cash flow

• Non-cash transaction

During the year ended December 31, 2017, the Company made the following transactions not involving cash and therefore not reflected in the consolidated statement of cash flows:

(i) Forward purchase of property, plant and equipment in the amount of R$105,102.

• Disclosure of interest and dividends

(i) The Company disclosures the dividends and interest on shareholders’ equity received as cash flow from investing activities, with the purpose of avoiding distortions in its cash flows from operation activities.

(ii) Interest received or paid is classified as cash flow from financing activities, as it is considered to refer to the costs of obtaining financial resources.

4 New standards and interpretations not yet effective

A number of new standards and amendments to standards are effective for annual periods beginning after January 1, 2018 and earlier application is permitted; however, the Group has not early adopted the following new or amended standards in preparing these consolidated financial statements.

a) Estimated impact of the adoption of IFRS 15 and IFRS 9

The Company estimated the impact of the adoption of IFRS 15—Revenue from Contract with Customers and IFRS 9—Financial Instruments on equity on January 1, 2018, based on valuations carried out up to the date of issuance these statements. The actual impacts of adopting the standards on January 1, 2018 may be different as the Company did not finalize the testing and evaluation of controls on these new standards and the new accounting policies are subject to change until the Company presents its first statements including the date of initial application.

The main components of the estimated adjustment are as follows:

i) recognition of incremental costs to obtain contract and customer payment to be paid; and

ii) impairment losses on financial assets.

b) IFRS 15—Customer Contract Revenue

IFRS 15 includes as a fundamental principle the recognition of revenue when goods or services are transferred to customers at the transaction price. Revenue is recognized according to this principle by applying a 5 step model:

• Step 1: Identify the contracts with the client;

• Step 2: Identify the performance obligations defined in the contract;

• Step 3: Determine the price of the transaction;

• Step 4: Allocate the price of the transaction to the performance obligations provided for in the agreement; and

• Step 5: Recognize revenue when (or as) the entity meets each performance obligation.

F-38

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

IFRS 15 introduces a comprehensive framework to determine whether and when revenue is recognized, and how much revenue is received. IFRS 15 replaces current revenue recognition standards.

The Company recognizes revenues from the following main sources:

(i) Sale of products

The Company recognizes sales revenues upon delivery to the customer. Delivery is considered to be the moment when the customer accepts the goods, and the risks and benefits related to the property are transferred. Revenue is recognized at this time as long as revenue and costs can be measured reliably, receipt of the consideration is probable and there is no continuous involvement of management with the products.

In accordance with IFRS 15, revenue must be recognized when the customer obtains control of the products. For contracts with customers where the sale is generally expected to be the only execution obligation, the adoption of IFRS 15 should have no impact on revenue and results. The Company expects revenue recognition to occur at a time when control of the good is transferred to the customer, usually at the time of delivery of the goods.

The Company operates in the production and distribution of lubricants including the brands Mobil and Comma, as well as the production and distribution of biomass pellets. Products are sold in contracts identified with individual customers and in sets, as a package of goods or services.

Some lubricant sales contracts cannot be purchased separately from a package of services. However, the goods and services are clearly distinct in the contracts. This sales modality represents two separate performance obligations and therefore revenue will be recognized for each of these performance obligations when control of the respective goods and services is transferred to the customer. Although IFRS 15 requires that the transaction price be allocated to different performance obligations based on the independent selling price, Management does not expect the allocation of revenues from the sale of lubricants and services rendered to be significantly different from that currently practiced, in which revenues are identified, measured and recorded separately.

(ii) Services provided

The Company provides gas distribution services through the subsidiary Comgás and logistics services through the subsidiary Cosan Logística. Based on the Company’s assessment, the fair value and selling prices of individual services are broadly similar. Therefore, the Company does not expect the application of IFRS 15 to result in significant differences in the recognition of revenue for these services.

(iii) Other effects

a) Incremental cost to obtain contracts

The Company has identified certain lubricant sales agreements that contain commission clauses. These clauses are under evaluation that are included as incremental costs associated with contract acquisition and are expressly chargeable to the customer. In the Company’s evaluation, when IFRS 15 is adopted, certain contracts may be recognized as assets due to the incremental cost of obtaining a customer agreement. These will be amortized on a systematic basis consistent with the transfer of the goods or services to the customers. On December 31, 2017, the amount of R$ 39,275 related to sales commissions was recognized as selling expenses.

The Company was presenting expenses related to contracts as sales expenses

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

b) Disposal of non-financial assets

The recognition and measurement requirements in IFRS 15 also apply to the recognition and measurement of any gains or losses on the disposal of non-financial assets (such as property, plant and equipment and intangible assets), when such disposal does not occur in the normal course of business. However, there is no expectation that the effect of these changes will be material to the Company.

(iv) Presentation and disclosure requirements

The presentation and disclosure requirements in IFRS 15 are more detailed than those contained in the current IFRS. The presentation requirements represent a significant change from the current practice and significantly increase the volume of disclosures required of the Company’s financial statements. Many of the disclosure requirements of IFRS 15 are new and the Company has assessed that the impact of some of them will be significant. In particular, the Company expects the explanatory notes to the financial statements to require expansion due to the disclosure of significant judgments made. These include determining the timing of the transaction price of contracts that include variable consideration, as the transaction price has been attached to the performance obligation and the assumptions used to estimate the individual selling prices of each performance obligation. In addition, as required by IFRS 15, the Company will disaggregate the recognized revenues from contracts that include the sale of both goods and services. In 2017, the Company continued to test the internal controls, policies and procedures required to collect and disclose the information required.

(v) Transition

The Company plans to adopt IFRS 15 using the cumulative effect method, with initial application of the standard at the initial date (January 1, 2018). As a result, the Company will not apply the requirements of IFRS 15 to the comparative period presented.

The Company plans to use the practical expedients for concluded contracts. This means completed contracts that have commenced and ended in the same comparative presentation period, as well as contracts that concluded at the beginning of the earliest period presented, will not be restated.

c) IFRS 9—Financial Instruments

In July 2016, the IASB International Accounting Standards Board issued the final version of IFRS 9—Financial Instruments which replaces IAS 39—Financial Instruments: Recognition and Measurement and all previous versions of IAS 39. The new standard brings together the three aspects of the accounting of financial instruments: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for fiscal years beginning on or after January 1, 2018, without prior application permission. With the exception of hedge accounting, retrospective application is necessary, but providing comparative information is not mandatory. For hedge accounting, the requirements are generally applied prospectively, with some limited exceptions.

The Company plans to adopt the new standard on the effective date required and will not restate comparative information. In 2017, the Company conducted a detailed impact assessment of the three aspects of IFRS 9. This evaluation is based on information currently available and may be subject to changes arising from reasonable and bearable information being made available by the Company in 2018, when it adopts IFRS 9. In general, the Company does not foresee any significant impact on the financial statements or shareholders’ equity, except for the effect of applying the impairment requirements of IFRS 9. The Company expects an increase in loss provisions resulting in a negative impact on shareholders’ equity as discussed below. In addition, the Company will implement changes to the classification of certain financial instruments.

F-40

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

i) Classification and measurement of financial assets

The Company does not expect a significant impact on its balance sheet or equity in applying the classification and measurement requirements of IFRS 9. We expect to continue to measure at fair value all financial assets currently held at fair value. Equity instruments, currently held for sale, with gains and losses recorded in profit or loss, will continue to be measured at fair value through profit or loss.

Loans and receivables are held by the Company to obtain contractual cash flows and should generate cash flows representing only payments of principal and interest. The Company analyzed the contractual cash flow characteristics of these instruments and concluded that they meet the amortized cost criteria in accordance with IFRS 9. Therefore, the reclassification to these instruments will not impact the balance sheet or equity.

The Company has assessed the impacts of gains and losses on financial liabilities attributable to its own risk and has not identified deviations that will result in an accounting for comprehensive income.

ii) Impairment – Financial Assets and Contractual Assets

IFRS 9 requires the Company to record the expected credit losses on all of its debt securities and trade accounts receivable, whether in 12 months or throughout the asset’s life. However, the Company has adopted the more simplified approach and will measure the expected credit losses over a lifetime because the trade accounts receivable and contractual assets do not represent a significant financing component. The provision will be determined by applying the percentage of expected losses on the financial assets to the overdue amounts and overdue loans that may impact the amount of provisioning expense for losses.

The estimated losses were calculated based on the actual experience of credit loss in recent years, and from observing the current conditions and forecasting future economic conditions.

The Company holds investments in debt instruments classified as securities, which are part of investment fund quotas measured at fair value through profit or loss. Therefore, no credit risk analysis of these assets is required.

iii) Hedge accounting

The Company has determined that all existing hedge relationships currently designated as effective hedging relationships will continue to qualify for hedge accounting in accordance with IAS 39. The Company has elected not to retrospectively apply IFRS 9 in the transition to the hedges where the Company excluded the items of progress of the hedge designation in accordance with IAS 39. As IFRS 9 does not change the general principles of how an entity responds to effective hedges, the application of the requirements of hedge of IFRS 9 will not have a significant impact on the Company’s financial statements.

iv) Other adjustments

In addition to the adjustments described above, associated with the adoption of IFRS 9, other items in the financial statements, such as deferred taxes, assets held for sale and liabilities associated with them, investments in associates and joint ventures will be adjusted as necessary. Foreign exchange differences in the conversion of foreign operations will also be adjusted.

(In thousands of Brazilian Reais – R$, unless otherwise stated)

d) IFRS 16 Leases

IFRS 16 introduces a single model for the accounting of leases in the balance sheet for tenants. A lessee recognizes a right of use asset that represents his right to use the leased asset and a lease liability that represents his obligation to make lease payments. Optional exemptions are available for short-term leases and low value items. The lessor’s accounting remains similar to the current standard, that is, lessors continue to classify leases as financial or operating.

IFRS 16 replaces existing lease standards, including IAS 17 Leasing Operations and IFRIC 4, SIC 15 and SIC 27 Complementary Aspects of Leasing Operations.

The standard is effective for annual periods beginning on or after January 1, 2019. Early adoption is permitted only for financial statements in accordance with IFRSs and only for entities that apply IFRS 15 Revenue from Contracts with Customers or before the date of initial application of IFRS 16.

The Company began an initial assessment of the potential impact on its financial statements. So far, the most significant impact identified is that the subsidiary Rumo will recognize new assets and liabilities for its operating leases. In the jointly-owned subsidiary Raízen, it is expected to have significant impacts on land leases. In addition, the nature of the expenses related to these leases will be changed, since IFRS 16 replaces the line operating lease expense due to depreciation of the right of use and interest on the lease liabilities. The Company has not yet decided whether to use the optional exemptions.

As a lessee, the Company may apply the standard using a:

- Retrospective approach; or

- Modified retrospective approach with optional practical expedients.

The lessee will apply this choice consistently to all of its leases. The Company should apply IFRS 16 initially on January 1, 2019. The Company has not yet determined which transition approach to apply.

The Company has not yet quantified the impact of adopting IFRS 16 on its assets and liabilities. The quantitative effect of the adoption of IFRS 16 will depend specifically on the transition method chosen, the use of practical expedients and recognition exemptions, and any additional leases that the Company will enter into. The Company expects to disclose its transition approach and quantitative information prior to adoption.

e) IFRIC 22 — Foreign Currency Transactions and Advance Consideration

IFRIC states that the date of the transaction for the purpose of determining the exchange rate should be the date on which the entity initially recognizes the non-monetary asset or liability arising from the payment or early receipt.

F-42

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

This interpretation takes effect for annual periods beginning on or after January 1, 2018. The initial adoption is permitted retrospectively, or prospectively.

Management conducted the analysis of the impacts of the initial adoption of IFRIC 22 and considered them to be immaterial. Thus, whether the adoption will be carried out prospectively or retrospectively is still being determined.

There are no other IFRS standards or IFRIC interpretations that have not come into effect and that are expected to have a material impact on the Company.

5    Operating segments

The following segment information is used by Cosan’s senior management (the “Chief Operating Decision Maker”) to assess the performance of the operating segments and to make decisions with regards to the allocation of resources. This information is prepared on a basis consistent with the accounting policies used in the preparation of the financial statements. Cosan evaluates the performance of its operating segments based on the measure of Earnings Before Interest Tax, Depreciation and Amortization (“EBITDA”). A reconciliation of EBITDA to profit (loss) is presented below.

Reported segments

(i)    Raízen Energia: production and marketing of a variety of products derived from sugar cane, including raw sugar (VHP), anhydrous and hydrated ethanol, and activities related to energy cogeneration from sugarcane bagasse. In addition, this segment holds interests in companies engaged in research and development on new technology;

(ii)    Raízen Combustíveis: distribution and marketing of fuels, mainly through a franchised network of service stations under the brand Shell throughout Brazil;

(iii)    Comgás: distribution of piped natural gas to part of the State of São Paulo (approximately 180 municipalities, including the region called Greater São Paulo) to customers in the industrial, residential, commercial, automotive, thermo generation and cogeneration sectors;

(iv)    Cosan Logística: logistics services for transport, storage and port loading of commodities, mainly for sugar products, leasing or lending of locomotives, wagons and other railway equipment; and

(v)    Moove: production and distribution of lubricants under the Mobil brand in Brazil, Bolivia, Uruguay and Paraguay, as well as European and Asian market with a Comma trademark.

Reconciliation

(i)    Cosan Corporate: other investments, in addition to the corporate activities of the Company. The Cosan Corporate segment’s includes the subsidiaries responsible for raising funds for the group.

Although Raízen Energia and Raízen Combustíveis are equity accounted joint ventures and are no longer proportionally consolidated since adoption of IFRS 11, senior management continues to review segment information. A reconciliation of these segments is presented in the column “Deconsolidated effects IFRS 11.”

The following statement of financial position and profit or loss selected information by segment was prepared on the same basis as the accounting practices used in the preparation of consolidated information:

Sale of credit rights

The Company recorded credit rights in the amount of R$ 426,438 as other assets and the respective legal fees in the amount of R$ 51,173 as other liabilities. In 2017, the requirements of the accounting policy were achieved and for that reason the credit right in the net amount of taxes of R$ 306,151 was recognized in the line of “other income,” with impact on cash flow statements.

In addition, the Company has additional claims to those mentioned above, which, because they are considered probable, were not recorded as representing contingent assets.

On December 21, 2017, there was a sale of credit rights related to the assets recorded in the balance sheet and also the contingent assets in the amount of R$ 1,340,000 (“purchase price”), arising from certain lawsuits, aiming at condemning the Union as a result of the fixing of sugar and alcohol prices below their cost of production. In addition to the acquisition price, the Company will be entitled to additional payments related to these receivables, provided that the result is positive. The additional payment will be calculated by applying 95% on the difference between the net value received from the Union credit rights by the transferee minus the return of the assignees and recognized in the results only upon receipt.

As a result of the sale of receivables, we had the following impacts:

(a) Financial discount recognized as financial expense in the amount of R$ 251,648 arising from the difference between the assignment of these rights for the amount of R$ 460,974 and the amount of assets previously recognized of R$ 712,622;

(b) Gain on the sale of credit rights net of tax and obligations in the amount of R$ 733,815 recorded as other revenues and. with impact on cash flow statements.

14 Investments in joint ventures

The Company entered into an agreement to form two joint ventures, accounting for 50% of the economic benefits of the companies. They are:

(i) Raízen Combustíveis which owns a network of, more than 6,027 fuel service stations throughout Brazil, 67 distribution terminals and 64 airports terminals for supplying aviation fuel; and

(ii) Raízen Energia, which produces and sells sugar, and ethanol and renders electric energy cogeneration services, the latter mainly from sugar cane bagasse. Raízen Energia is responsible for the production of, approximately, 2 billion liters of ethanol per year to supply the domestic and foreign market, 4.2 million tons of sugar and 940 MW of installed capacity of electricity. Raízen Energia cultivates harvests and processes sugar cane—the main raw material used in the production of sugar and ethanol.

Cosan has joint control over Raízen Combustíveis and Raízen Energia by virtue of its 50% share in the equity of both companies and the requirement for unanimous consent by all shareholders over decisions related to the significant activities. The investments have been classified as joint ventures under IFRS 11 and therefore the equity method of accounting is used for all periods presented in these consolidated financial statements.

Impairment testing of cash-generating units (“CGU”) goodwill

a) Cosan Logistics

The Company annually tests recoverable amounts of goodwill arising from business combination operations. Property, plant and equipment and defined-intangible assets that are subject to depreciation and amortization are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

For the purposes of impairment analysis, concession contracts were defined as cash-generating units. The base date for evaluation and annual testing is September 30.

During the year ended December 31, 2017, we did not identify impairment indicators, so that no impairment test was required for fixed assets and intangible assets with a defined useful life.

The balance of goodwill recorded by the Company is associated with the port lifting operation and terminals, so this cash-generating unit needs to be tested annually.

The recoverable amount of this cash-generating unit was determined by the net sales value of the unit, using the EBITDA multiples technique.

The main assumptions used were (i) EBITDA generated by the cash-generating unit in 2017, and (ii) the average of the multiples practiced by market agents for companies in the Company’s industry.

Cosan Limited

Notes to the consolidated financial statements

(In thousands of Brazilian Reais – R$, unless otherwise stated)

The calculation resulted in a recoverable amount of R$ 1,709,000, compared to a book value of R$ 811,618, which includes property, plant and equipment and intangible assets.

In the year ended December 31, 2017, no assets and goodwill had their consolidated value reduced by impairment. The determination of the recoverability of the assets depends on certain key assumptions as described above that are influenced by the market, technological, and economic conditions in place at the time this recovery is tested and, therefore, it is not possible to determine whether new losses by recovery will occur in the future and, if they occur, whether these would be material.

b) Cosan S.A.

The Company annually tests recoverable amounts of goodwill (intangible assets with indefinite useful lives) arising from business combinations operations. Property, plant and equipment and defined-intangible assets that are subject to depreciation and amortization are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable, which is not the case for the year.

The combined carrying amounts of goodwill allocated to each cash-generating unit are as follows:

	Consolidated
	December 31, 2017		December 31, 2016
Moove cash generating unit		751,391		614,765
Cosan cash-generating unit other business		43		43
Total goodwill		751,434		614,808

The recoverable amount is determined based on calculations of the value in use, using the discounted cash flow determined by Management based on budgets that take into account the assumptions related to each business, using information available in the market and previous performance. Discounted cash flows were drawn up over a ten-year period and carried forward in perpetuity without considering a real growth rate. Management understands the use of periods greater than five years in the preparation of discounted cash flows as it reflects the estimated time of use of the asset and business groups.

The main assumptions used mainly consider the expectation of growth of the operations based on the Gross Domestic Product segmented, as well as taking into account the levels of average growth experienced in the last years and other macroeconomic aspects, as well as expectation of the price of sales of commodities, using discount rates that reflect specific business-related risks.

All of these future cash flows were discounted at a rate of 10.4% (weighted-average cost of capital) and a growth rate of the final value of 4% from 2027 reflecting specific risks related to the relevant assets in its cash generating unit.

An increase of 6.3 percentage points in the discount rate should change so that the estimated recoverable amount is equal to the book value. The dollar has an impact on projections and, therefore, a fluctuation of in exchange rate would have an effect on the estimate.

As of December 31, 2017 no expense for impairment of assets and goodwill was recognized. The determination of the recoverability of the assets depends on certain key assumptions as described above that are influenced by the market, technological and economic conditions in place at the time that such recovery is tested, and therefore, it is not possible to determine whether new reduction losses of recovery will occur in the future and, if they occur, whether these would be material.

Court Discussion

The Company is challenging in court the economic and financial unbalance of certain leases and concession contracts.

In April 2004, Rumo Malha Paulista filed an interlocutory injunction and subsequently Declaratory Action before the 21st Federal Court of Rio de Janeiro questioning the economic and financial unbalance of the Lease and Concession Agreements, due to the high disbursement incurred by the Company for the payment of labor judicial proceedings and other expenses involved, which are the responsibility of Rede Ferroviária Federal S.A., as provided in the bidding documents.

Rumo Malha Paulista required an injunction to suspend payment of installments due of the concession and lease agreements and to offset the credit balance resulting from labor amounts paid by Rumo with the amount charged by the Union. In April 2005, the injunction was granted, suspending the enforceability of installments for 90 days by determining the completion of expertise. In July 2005, the suspension was extended for another 90 days. In September 2005, the injunction was overturned by the Federal Court of Rio de Janeiro. In January 2006, the suspension of payment of installments was granted, by means of judicial deposit. The amount related to the lease payment was deposited in court until October 2007, when the Company obtained a court order to replace the judicial deposits with a bank guarantee. In October 2015, a decision was handed down that partially upheld the action recognizing the occurrence of economic and financial balance of the agreements, allowing the Company to perform the part of compensation of the amounts claimed in the match against presented debt. Nevertheless, the Company believes that all amounts discussed shall be offset against payables based on clauses 7 and 10 of the bidding documents.

Management, supported by the opinion of its legal counsel, assesses the chances of success as probable, but the financial liability remains recognized as it is a contractual obligation not yet discharged and still depend on offsetting with the Company’s reimbursement rights.

Rumo Malha Oeste also claiming the reestablishment of the economic-financial balance, lost by the cancellation of transportation contracts at the time of privatization, change in the regulatory environment and conditions set forth in the Privatization Tender—additionally, the growth forecasts that defined the value of the business did not materialize. The lawsuit is filed with the 16th Federal Court of Rio de Janeiro. To proceed with the legal discussion, the Company offered government securities (Treasury Bills—LFT) as an execution guarantee. In March 2008, the Company was authorized to replace the guarantee by a bank guarantee and in May 2008, the Company redeemed the treasury bills. In December 2014, a decision was handed down that upheld the action recognizing the occurrence of economic and financial balance of the contracts, with the amounts involved and certain related aspects still to be determined. In December 2015, the replacements of guarantee letters presented by Rumo were replaced with an insurance policy.

Management, supported by the opinion of its legal counsel, assesses the chances of success as probable, but the financial liability remains recognized as it is a contractual obligation not yet discharged and must still be offset against the company’s right to be reimbursed.

Judicial deposits at December 31, 2017 concerning the above claims totaled:

	December 31, 2017		December 31, 2016
Rumo Paulista		119,806		118,820
Rumo Oeste		20,690		19,464
		140,496		138,284

The judicial deposits are recorded in the “regulatory” group, as described in note 24.

20 Commitments

(a) Commitments for the acquisition of assets and regulatory targets

With the postponement of the 2015 Five-Year Tariff Review as a result of the publication of Resolutions ARSESP 493 and 494, both of May 27, 2014, which approved the “Tariff Review Process of Gas distribution companies in the State of São Paulo, defining event schedule,” and the “provisional adjustment of marketing margins of São Paulo Gas Company – Comgás,” there is no set regulatory commitment as of December 31, 2017 and 2016.

The tariffs for the supply of gas to the different customer segments are authorized by the concession authority. In accordance with the terms of the Concession Agreement, the differences between the cost component of gas included in the tariffs charged to the customers and the actual cost of gas incurred are determined on a monthly basis and charged or credited to a regulation account (regulatory account).

Periodically, charges or credits in the tariffs are determined by the regulator with the objective of amortizing the amounts accumulated in this account.

The balance of this account is considered as an asset or as a liability, pursuant to the regulator’s set of accounts and for income tax purposes. However, this account is not recognized under IFRS, because the respective balance is not considered as an asset or as a liability, as its realization or liquidation depends on further purchases by the Company’s consumers.

(i) During the period from October 2003 to November 2006, the Company, through its subsidiary CLE, offset the FINSOCIAL tax against several other federal taxes, based on a final court decision in September 2003 following a decision that challenged the constitutionality of the FINSOCIAL. No judicial deposits were made.

(ii) The amounts that have been provisioned refer to tax assessments by the tax authorities related to several types of ICMS credits. Amongst them: (a) assessment notice related to ICMS payments for the purchase of raw materials which are considered for “use and consumption,” therefore, not eligible for compensation; (b) assessment, as sole obligor, for withholding of ICMS on tolling agreement from an agricultural partnership with Central Paulista Ltda. Açúcar e Álcool; (c) assessment notice related to the ICMS offset arising from the fact that the forward presumed profit is bigger than the consummated profit, under tributary substitution regime.

(iii) The amounts that have been provisioned are mainly related to social security contributions levied on company´s earnings, pursuant to Article 22-A of the 8.212/91 Law, which are being challenged on the grounds of constitutionality. Judicial deposits have been made for the corresponding amounts.

(i) In summary, these demands relate basically:

• Tax assessments issued against the Company for unpaid ICMS and non-compliance with accessory obligations, in connection with the agricultural and industrial tolling services partnership in specified periods between May and December of 2006 and 2007. In these cases the company is jointly and severally liable;

• ICMS levied on the remittances for the export of crystallized sugar, which the Company understands are tax exempt. However, the tax authorities classify crystallized sugar as a semi-finished product, which is therefore subject to ICMS;

• ICMS withholding rate differences on the sale of ethanol to companies located in other states, which subsequently had their tax registrations revoked;

• Disallowance of ICMS tax credits on the sale of diesel fuel to customers engaged in the agro industrial business.

• ICMS payments on inventory differences arising from erroneous calculations by the State Tax Administration;

• ICMS related to the fiscal war between the states;

• The subsidiary CLE has been discussing administratively the ICMS tax credits arising from the transfer of excess credits to its centralizing unit in the period from May 2012 to January 2013.

• The State Tax Administration assessed the rail concessions for non-taxation of ICMS on invoices for the provision of rail freight services for export. There is a favorable position for taxpayers in the higher courts; and

• Assessment from State Tax Administration of São Paulo on the grounds that the Company was not authorized to operate as a general warehouse in that state. At the time of the release of the state registration, the tax authorities allowed the Company’s activities, including issuance of invoices.

Tax assessment notice issued by the São Paulo State Treasury Department, against Rumo Malha Paulista, covering the period from February 2011 to July 2015, with the indication of infractions for alleged lack of payment of ICMS on railroad services for export and ICMS credits accrual considered undue.

(ii) Tax assessment notices issued requiring additional income tax, social contribution, PIS and COFINS, for the calendar years 2005 to 2008 as a result of the following alleged violations: (a) improper exclusion of financial costs arising from loans with foreign financial institutions from the corporate income tax and social contribution calculation basis, (b) improper exclusion of financial income from securities issued by the Government of Austria and the Government of Spain from the corporate income tax and social contribution calculation basis (c) no inclusion, in the corporate income tax and social contribution calculation basis, of gains earned in swap operations, and non-taxation of financial income resulting from these contracts by PIS and COFINS, (d) improper offsetting from corporate income tax and the social contribution calculation basis by using PIS and COFINS credits.

A favorable decision in the Administrative Court (CARF) may change its classification for remote losses.

(iii) The Company, and its controlled companies, received assessment notices based on the following: (a) tax benefits that arose from the deduction of goodwill amortization, (b) exchange variation and interest incurred as the tax authorities understand that the corporate transactions carried out were intended to postpone the settlement of debt contracted abroad through the issuance of Perpetual Bonds, in order to reduce Positive result of exchange variation, and (c) the subsidiary Comgás was known of the no recognition of the offsetting procedures made in 2015, using income taxes credits (IRPJ);

(iv) Refers mainly to the reversal of PIS and COFINS credits, provided by Laws 10.637/2002 and 10.833/2003, respectively. Those reversals arise from a differing interpretation of the laws by the tax authorities in relation to raw materials. These discussions are still at the administrative level.

Tax authorities assessed the Rumo Malha Paulista for non-taxation of PIS and COFINS on revenues from mutual traffic and rite of passage billed against Rumo Malha Norte. The chance of loss is considered possible as tax already has been collected by the concessionaire responsible for transporting from origin.

(v) The subsidiary CLE received an assessment notice related to the withholding income tax on an alleged capital gain arising from the acquisition of assets of foreign companies.

The subsidiary Comgás received an assessment notice related to the withholding income tax on an alleged capital gain of a former shareholder due to contractual arrangements.

Rumo Malha Paulista had part of its IRPJ credit balance glossed based on the argument that the Company would not be entitled to IRRF compensation on swap transactions.

(vi) The legal proceeding related to INSS payment with possible unfavorable outcome involve the following: (a) the legality and constitutionality questioning Normative Instruction MPS/SRP Nº 03/2005, which restricted the constitutional immunity over social contributions on export revenues through direct sales, consistent with the manner exports made via trading companies are now taxed; (b) assessment of SENAR (Rural apprenticeship scheme) social contribution on direct and indirect exports, in which the tax authorities disregard the right to constitutional immunity;

(vii) Legal demands related to the SRF Normative Instruction no. 67/98 that allowed for the refunding of IPI tax payments for sales of refined sugar from January 14, 1992 through November 16, 1997.

(viii) Tax assessment issued by the Brazilian Tax Authority in 2011 and 2013 against Rumo S.A. concerning: (a) amortization expense disallowance based on future profitability, as well as financial expenses; and (b) non-taxation of supposed capital gain on disposal of equity interest in a Company of the same group.

(ix) The Company was assessed due to the disregard of the tax benefits of REPORTO (PIS and COFINS suspension), on the grounds that the locomotives and freight cars purchased in 2010 were used outside the limits area of the port. Therefore, the Company was assessed to pay PIS and COFINS, as well as an isolated fine corresponding to 50% of the value of acquired assets.

(x) SRF Normative Instruction no. 67/98 allowed for the refunding of IPI tax payments for sales of refined sugar from January 14, 1992 through November 16, 1997. Consequently, the Company applied for the offsetting of amounts paid during the periods against other tax liabilities. However, the tax authorities denied its application for both the reimbursement and offsetting of these amounts. The Company has challenged this ruling in an administrative proceeding.

(xi) The Tax Authority partially rejected the Company requests for payment of its federal tax debts, pursuant to provisional measure n. 470 (MP 470), on the ground that the tax loss offered is not sufficient to settle the respective debts. The likelihood of loss is considered as possible since the results are indicated existed and are available for such use.

(xii) Decrease related to favorable decisions from administrative sphere.

Civil, labor, regulatory and environmental

a) Judicial claims deemed to be probable losses, fully accrued

• Civil – refers mainly to compensation for material and moral damages, class actions for abstaining from straw burning sugarcane and execution of environmental nature.

• Labor – represent labor claims filed by former employees and employees of service providers who question, among others, payment of overtime, night and dangerous, job reinstatement, compensation for accidents at work and reimbursement of discounts from payroll, such as confederative and assistance contributions, union dues and other.

27 Earnings per share

The calculation of basic earnings per share has been made by dividing the profit attributable to shareholders of the parent by the weighted-average number of ordinary shares outstanding during the year excluding ordinary shares purchased by the company and held as treasury shares (Note 26).

The calculation of diluted earnings per share has been made by dividing the profit attributable to shareholders of the parent, adjusted to assume conversion of all dilutive potential ordinary shares at subsidiaries by the weighted-average number of shares outstanding during the year excluding ordinary shares purchased by the company and held as treasury shares (Note 26). The Company’s subsidiaries have two categories of potential dilutive effects: share options and put options. For the share options, a calculation is done to determine the effect of the dilution in the profit attributable to shareholders of the parent due the exercise of the share options at subsidiaries. For the put option, is assumed to have been converted into ordinary shares, and the profit attributable to shareholders of the parent is adjusted.

The following table sets forth the calculation of earnings per share (in thousands of Brazilian Reais, except per share amounts):

	December 31, 2017			December 31, 2016			December 31, 2015
Profit attributable from continued operation to ordinary equity holders for basic earnings		551,021			325,132			381,392

The non-controlling interests of the indirect subsidiary Brado Logística S.A. have the right to exercise a liquidity option provided for in the shareholders’ agreement signed on August 5, 2013. This option would exchange all Brado shares held by such minority shareholders by shares of Rumo. The exchange ratio shall take into account the economic value for both Brado and Rumo shares. At the Company’s exclusive discretion, an equivalent cash payment is also possible.

For the year ended December 31, 2017, 3,558,449 share options from indirect subsidiary Rumo S.A. and 20,621,948 share options from indirect subsidiary Brado Logística S.A. were excluded from the diluted weighted-average number of ordinary shares calculation because their effect would have been anti-dilutive.

For the year ended December 31, 2017, 11,171,300 shares related to the share repurchase plan of subsidiary Cosan S.A. have an antidilutive effect, so they were not considered in the diluted earnings per share analysis.

Risk management structure

The management has overall responsibility for the establishment and oversight of the Company’s risk management framework. The board of directors has established the Risk Management Committee, which is responsible for developing and monitoring the Company’s risk management policies. The committee reports regularly to the board of directors on its activities.

The Company’s risk management policies are established to identify and analyze the risks faced by the Company, to set appropriate risk limits and controls and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Company’s activities. The management, through its training and management standards and procedures, aims to maintain a disciplined and constructive control environment in which all employees understand their roles and obligations.

The Audit Committee oversees how management monitors compliance with the Company’s risk management policies and procedures, and reviews the adequacy of the risk management framework in relation to the risks faced by the Company. The Audit Committee is assisted in its oversight role by Internal Audit. Internal Audit undertakes both regular and ad hoc reviews of risk management controls and procedures, the results of which are reported to the Audit Committee.

All derivative activities for risk management purposes are carried out by specialist teams that have the appropriate skills, experience and supervision. It is the Company’s policy that no trading in derivatives for speculative purposes may be undertaken.

The usage of financial instruments in order to protect against these areas of volatility is determined through an analysis of the risk exposure that management intends to cover.

Credit risk from balances with banks and financial institutions is managed by the Company’s treasury department in accordance with the Company’s policy. Investments of surplus funds are made only with approved counterparties and within credit limits assigned to each counterparty. Counterparty credit limits are reviewed on an annual basis and may be updated throughout the year. The limits are set to minimize the concentration of risks and therefore mitigate financial loss through potential counterparty’s failure to make payments.

(ii) Customer credit risk is managed by each business unit subject to the Company’s established policy, procedures and control relating to customer credit risk management. Credit quality of the customer is assessed based on an extensive credit rating scorecard and individual credit limits are defined in accordance with this assessment. Outstanding customer receivables are regularly monitored and any shipments to major customers are generally covered by letters of credit or other forms of credit insurance.

The requirement for impairment is analyzed at each reporting date on an individual basis for major clients. Additionally, a large number of minor receivables are grouped into homogenous groups and assessed for impairment collectively. The calculation is based on actual incurred historical data.

The maximum exposure to credit risk at the reporting date is the carrying value of each class of financial assets. Management considers that the credit risk is covered by the allowance for doubtful accounts.

Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Company’s approach to managing liquidity is to ensure, as far as possible, that it will have sufficient liquidity to meet its liabilities when they are due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Company’s reputation. As mentioned in Note 1, Management has been working on measures to enable the subsidiary Cosan Logística to honor its Commitments.

The non-derivative financial liabilities of the Company sorted by due dates (based on undiscounted cash flows contracted) are as follows:

Market risk

Market risk is the risk that changes in market prices – such as foreign exchange rates, interest rates and equity prices – will affect the Company’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return.

The Company uses derivatives to manage market risks. All such transactions are carried out within the guidelines set by the Risk Management Committee. Generally, the Company seeks to apply hedge accounting to manage volatility in profit or loss.

a) Foreign exchange risk

As at December 31, 2017 and December 31, 2016, the Company and its subsidiaries had the following net exposure to the exchange rate variations on assets and liabilities denominated in Dollar:

	December 31, 2017			December 31, 2016
Cash and cash equivalents		782,103			424,334
Trade receivables		25,797			11,940
Advances to suppliers		—			58,866
Trade payables		(13,230	)		(22,005	)
Loans, borrowings and debentures		(8,919,712	)		(6,323,330	)

Contingent consideration		(64,213	)		(68,388	)
Payables to related parties		(210,497	)		—
Derivative financial instruments (i)		7,323,116			6,413,619
Foreign exchange exposure, net		(1,082,946	)		495,036

(i) These balances are equivalent to the notional amount in US Dollars converted to R$ at the Dollar rate of December 31, 2017 and December 31, 2016 respectively.

Sensitivity analysis on changes in foreign exchange rates:

The probable scenario was defined based on the U.S. Dollar market rates as at December 31, 2017, which determines the fair values of the derivatives at that date. Stressed scenarios (positive and negative effects, before tax effects) were defined based on changes of a 25% and 50% to the U.S. Dollar exchange rates used in the probable scenario.

Based on the financial instruments denominated in U.S. Dollars at December 31, 2017, the Company performed a sensitivity analysis by increasing and decreasing the exchange rate for R$/US$ by 25% and 50%. The probable scenario considers the estimated exchange rates, made by a specialized third part, at the due date of the transactions for the companies with functional currency Real (positive and negative, before tax effects), as follows:

	Exchange rate sensitivity analysis (R$/US$)
	December 31, 2017		Scenario
			Probable		25%		50%		-25%		-50%
US$		3.3080		3.4000		4.2500		5.1000		2.5500		1.7000

The external source used by the company for market projections was a specialized consultant.

Considering the above scenario the profit or loss would be impacted as follows:

b) Interest rate risk

The Company and its subsidiaries monitor the fluctuations in variable interest rates in connection with its borrowings, especially those that accrue interest using LIBOR, and uses derivative instruments in order to minimize variable interest rate fluctuation risks.

Sensitivity analysis on changes in interest rates:

A sensitivity analysis on the interest rates on loans and borrowings in compensation for the CDI investments with pre-tax increases and decreases of 25% and 50% is presented below:

	December 31, 2017
Exposure interest rate(i)	Probable			25%			50%			-25%			-50%

(i) The external source used by the company for market projections was a specialized consultant.

(ii) The probable scenario for derivative financial instruments represents the current mark-to-market balance.

Financial instruments fair value

The fair values of the financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The following methods and assumptions were used to estimate the fair values:

• The cash and cash equivalents, accounts receivable, trade receivables, trade payables and other current liabilities approximate their carrying amount largely due to the short-term maturity of these instruments.

• The fair values of the quoted notes and bonds are based on price quotations at the reporting date. The fair value of unquoted instruments, loans from banks and other financial liabilities, obligations under finance leases, as well as other non-current financial liabilities is estimated by discounting future cash flows using rates currently available for debt on similar terms, credit risk and remaining maturities.

• The market value of the Senior Notes are listed on the Luxembourg Stock Exchange (Note 17) is based on their quoted market price are as follows:

Senior Notes Due	Company	December 31, 2017	December 31, 2016
2018	Cosan S.A.	100.37%	95.68%
2023	Cosan S.A.	101.54%	96.05%
2024	Rumo S.A.	107.86%	—
2027	Cosan S.A.	108.14%	100.65%
2024	Cosan	102.79%	—

• The fair value of Perpetual Notes listed on the Luxembourg Stock Exchange (Note 17) is based on their quoted market price as December 31, 2017 of 102.83% (100.03% at December 31, 2016) of the face value of obligations at December 31, 2017.

• The fair value of other loans and financing, the respective market values substantially approximate the amounts recorded due to the fact that these financial instruments are subject to variable interest rates (Note 17).

The Company and its subsidiaries enter into derivative financial instruments with various counterparties, principally financial institutions with investment grade credit ratings. Derivatives valued using valuation techniques with observable market data refer mainly to interest rate swaps and foreign exchange forward contracts.

The fair value of derivative financial instruments is determined using valuation techniques and observable market data. The valuation techniques applied more often include pricing models and swaps contracts, with a present value calculation. The models consider various data, including counterparty credit quality, spot exchange rates, forward curves of interest rates and curves of the commodity term rates.

The Company annually evaluates the credit risk of its counterparties and a possible impact on the fair value of debts and derivatives. In most cases, since the Company is a borrower, the result, in addition to immaterial, reduces its liabilities.

In order to measure the credit risk of the parties involved in the derivative instruments, the Company uses the forward rate structure disclosed by B3 and adds discount rates that reflect the risk counterparty credits that are applied to each of the maturities in the calculation of the fair value of all financial instruments. The Company adopts counterparty ratings for positive flows and its own rating for negative flows, available on the market and disclosed by renowned rating agencies, as a necessary premise to extract the probability of default.

(i) The valuation of the contingent consideration considers the present value of expected payment, discounted using a risk-adjusted discount rate. The expected payment is determined by considering the probable scenarios of forecast revenue and EBITDA, the amount to be paid under each scenario and the probability of each scenario. The significant unobservable inputs are the forecast of the annual growth rate of revenue, EBITDA margin forecast and the 13% discount rate adjusted for risk.

Hedge accounting

Currently the Company has adopted the hedge accounting of fair value for some its operations that both the hedging instruments and the hedged items are accounted for at fair value through profit or loss. Operations and accounting effects of this adoption are as follows:

	Debt			Derivative			Total
At January 1, 2017		1,534,072			(146,697	)		1,387,375
Initial measurement		2,461,836			—			2,461,836
Interest amortization		(173,186	)		(82,755	)		(255,941	)
Fair value		395,499			82,928			478,427
At December 31, 2017		4,218,221			(146,524	)		4,071,697

In May 2017 the indirect subsidiary Comgás designated hedge accounting of fair value for its “Debentures 5ª issuance” loan agreement. Using derivative operations, Comgás protected its future cash flow by changing the interest risk linked to the IPCA (National Wide Consumer Price Index) by percentages of the CDI (Interbank deposit rate).

Capital management

The Company’s policy is to maintain a robust capital base to promote the confidence of investors, creditors and the market, and to ensure the future development of the business. Management monitors that the return on capital is adequate for each of its businesses.

Futura		(21,739	)		23,800
Futura II		(93	)		98

34 Share-based payment

On December 31, 2017 the Company and its subsidiaries have share-based payment plans (i) Stock Option Plan which provides an option to executives to buy the shares of the Company and its subsidiaries; (ii) Stock Based Compensation Plan which provides to executives a grant of shares of the Company and its subsidiaries.

The plans have been administered by the Board of Directors of each Company and its subsidiaries, at its option, by a Committee, within the limits established in the guidelines for the elaboration and structuring of each plan and in the applicable legislation.

34.1 Stock option plan

a) Cosan S.A. (equity-settled)

The number of options granted in the stock option plan is determined by the Board of Directors or specific Committee, with the option exercise price equivalent to the average closing price of the share in the last thirty three B3 trading sessions prior to the date of grant (“Grant date”). The exercise price is updated monthly by the variation of the Extended Consumer Price Index (“IPCA”) between the grant date and the month prior to the notification of exercise of the option by the beneficiary.

The vesting period and the position of the outstanding options are as follows:

Share option programs	Expected life (years)	Interest rate—%		Expected volatility—%		Number of instruments on December 31, 2017							Market price on grant date		Exercise price at December 31, 2017		Fair value at grant date—R$(i)

(b) Measurement of the fair value

34.2. Stock-Grant Plan

The stock grants are plans under which shares may be issued by the company and its subsidiaries to the executives for the services provided with no cash consideration.

Shares issued by the company and its subsidiaries to the executives are acquired on-market prior to the issue. Shares held by the company and its subsidiaries and not yet issued to executives at the end of the reporting period are shown as treasury shares in the financial statements.

Under the plan, eligible executives may be granted ordinary shares or cash, at the choice of the Company, for no cash consideration. The number of shares issued to participants in the plan is the offer amount divided by the weighted average price at which the company’s shares are traded on the B3 during the last 30 days up to and including the date of grant. The shares are recognized at the closing share price on the grant date (grant date fair value) as an issue of treasury shares by the trust and as part of employee benefit costs in the period the shares are granted.

In September 2017, the board of directors decided to reward executives for their contribution to the performance of the Company by granting them 255,000 share appreciation rights.

Upon surrender for cancellation of any temporary Notes the Company will execute and the Trustee will authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes will be entitled to the same benefits under this Indenture as definitive Notes.

Section 2.07    Cancellation. The Company at any time may, but shall not be obligated to, deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold. Any Registrar, Transfer Agent or Paying Agent will forward to the Trustee any Notes surrendered to it for transfer, exchange or payment. The Trustee will cancel all Notes surrendered for transfer, exchange, payment or cancellation and dispose of them in accordance with its normal procedures. The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation.

Section 2.08    CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” and “ISIN” numbers, and the Trustee will use CUSIP numbers or ISIN numbers in notices of redemption or exchange or in Offers to Purchase as a convenience to Holders, the notice to state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or exchange or Offer to Purchase. The Company will promptly notify the Trustee in writing of any change in the CUSIP or ISIN numbers.

27

Section 2.09    Registration, Transfer and Exchange. (a) The Notes will be issued in registered form only, without coupons, and the Company shall cause the Registrar to maintain a register (the “Register”) of the Notes, for registering the record ownership of the Notes by the Holders and transfers and exchanges of the Notes. Upon written request from the Company, the Registrar shall provide the Company with a copy of the Register to enable it to maintain a register of the Notes at its registered office.

(b)    (i) Each Global Note will be registered in the name of the Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend.

(ii)    Each Global Note will be delivered to the Trustee as custodian for DTC. Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except (1) as set forth in Section 2.09(b)(iv) and (2) transfers of portions thereof in the form of Certificated Notes may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section and Section 2.10.

(iii)    Agent Members will have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary or its nominee, as the case may be, shall be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent Member) to take any action which a Holder is entitled to take under this Indenture or the Notes, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

(iv)    If (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for a Global Note and a successor depositary is not appointed by the Company within 90 days of the notice or (y) an Event of Default has occurred and is continuing and the Trustee has received a written request therefor from the Depositary, the Company will promptly exchange each beneficial interest in the Global Note for one or more Certificated Notes in authorized denominations having an equal aggregate principal amount registered in the name of the owner of such beneficial interest, as identified to the Company and the Trustee by the Depositary in writing, and the Trustee will cancel the Global Note. If such Note does not bear the Restricted Legend, then the Certificated Notes issued in exchange therefor will not bear the Restricted Legend. If such Note bears the Restricted Legend, then the Certificated Notes issued in exchange therefor will bear the Restricted Legend.

28

(v)    None of the Trustee or Agents shall have any responsibility or obligation to any beneficial owner of an interest in a Global Note, any agent member or other member of, or a participant in, the Depositary or other person with respect to the accuracy of the records of the Depositary or any nominee or participant or member thereof, with respect to any ownership interest in the Global Note or with respect to the delivery to any agent member or other participant, member, beneficial owner or other person (other than the Depositary) of any notice or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of the Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary, subject to its applicable rules and procedures. The Trustee and Agents may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its agent members and other members, participants and any beneficial owners. The Depositary may be treated by the Trustee and the Agents as the owner of the Global Note for all purposes whatsoever.

(c)    Each Certificated Note will be registered in the name of the holder thereof or its nominee.

(d)    A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by Section 2.10. The Registrar will promptly register any transfer or exchange that meets the requirements of this Section by noting the same in the register maintained by the Registrar for the purpose; provided that:

(x)    no transfer or exchange will be effective until it is registered in such Register, and

(y)    the Trustee will not be required (i) to issue or cause the registration of the transfer of or exchange of any Note for a period of 14 days before a selection of Notes to be redeemed or purchased pursuant to an Offer to Purchase, (ii) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of any Note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase is to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to register the transfer of or exchange any Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will treat the Person in whose name the Note is registered as the owner and Holder thereof for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary.

From time to time the Company will execute and the Trustee will authenticate additional Notes as necessary in order to permit the registration of a transfer or exchange in accordance with this Section.

29

No service charge will be imposed in connection with any transfer or exchange of any Note, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange pursuant to subsection (b)(iv)).

(e)    (i) Global Note to Global Note. If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global Note, the Trustee will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

(ii)    Global Note to Certificated Note. If a beneficial interest in a Global Note is transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (y) deliver one or more new Certificated Notes in authorized denominations having an equal aggregate principal amount to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name provided in writing by the Depositary of such transferee or owner, as applicable.

(iii)    Certificated Note to Global Note. If a Certificated Note is transferred or exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such Certificated Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and credit such increase to the account of the Agent Member at the Depositary as instructed in writing by the Holder of the Certificated Note and (z) in the event that such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

(iv)    Certificated Note to Certificated Note. If a Certificated Note is transferred or exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Note (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

30

(v)    Responsibility and Liability for Actions of Depositary. Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.

Section 2.10    Restrictions on Transfer and Exchange. (a) The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section and Section 2.09 and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and procedures of the Depositary. The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(b)    Subject to paragraph (c), the transfer or exchange of any Note (or a beneficial interest therein) of the type set forth in column A below for a Note (or a beneficial interest therein) of the type set forth in column B below may only be made in compliance with the certification requirements (if any) described in the clause of this paragraph set forth opposite column C below.

In the event that (i) a duly completed and executed Regulation S Certificate is delivered to the Trustee or (ii) a Certificated Note that does not bear the Restricted Legend is surrendered for transfer or exchange, upon transfer or exchange the Trustee will deliver a Certificated Note that does not bear the Restricted Legend.

(4)    The Person requesting the transfer or exchange must deliver or cause to be delivered to the Trustee a duly completed and executed Rule 144A Certificate.

(c)    No certification is required in connection with any transfer or exchange of any Note (or a beneficial interest therein) after such Note is eligible for resale pursuant to Rule 144(k) under the Securities Act (or a successor provision); provided that the Company has provided the Trustee with an Officers’ Certificate to that effect, and the Company may require from any Person requesting a transfer or exchange in reliance upon this clause an Opinion of Counsel and any other reasonable certifications and evidence in order to support such certificate. Any Certificated Note delivered in reliance upon this paragraph will not bear the Restricted Legend.

(d)    The Trustee will retain copies of all certificates, opinions and other documents received in connection with the transfer or exchange of a Note (or a beneficial interest therein), and the Company will have the right to inspect and make copies thereof at any reasonable time upon written notice within a reasonable period of time to the Trustee.

ARTICLE 3

ADDITIONAL AMOUNTS; REDEMPTION

Section 3.01    Additional Amounts. (a) All payments by the Company in respect of the Notes will be made without withholding or deduction for or on account of any present or future taxes, duties, assessments, or other governmental charges of whatever nature imposed or levied by or on behalf of any jurisdiction in which the Company is organized or is a resident for tax purposes, or any other jurisdiction through which any payments under the Notes are made by or on behalf of the Company, or any political subdivision thereof, having power to tax (a “Relevant Jurisdiction”), unless the Company is required by law to deduct or withhold such taxes, duties, assessments, or governmental charges. In such event, the Company will make the required deduction or withholding, make payment of the amount so withheld to the appropriate governmental authority and pay such additional amounts as may be necessary to ensure that the net amounts received by Holders of Notes after such withholding or deduction equal the amounts that would have been received in respect of the Notes in the absence of such withholding or deduction (“Additional Amounts”).

No such Additional Amounts shall be payable:

(i)    to, or to a third party on behalf of, a Holder where the Holder or beneficial owner is liable for any present or future taxes, duties, assessments or governmental charges in respect of a Note by reason of the existence of any present or former connection between the Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of the Holder or beneficial owner, if the Holder or beneficial owner is an estate, a trust, a partnership, a limited liability company or a corporation) or beneficial owner and the Relevant Jurisdiction, including, without limitation, the holder or beneficial owner (or the Holder’s or the beneficial owner’s fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged or deemed to be engaged in a trade or business or present therein or having, or having had, a permanent establishment therein, other than the mere holding of the Note or the enforcement of rights and the receipt of payments with respect to the Note;

32

(ii)    in respect of Notes surrendered (if surrender is required) more than 30 days after the Relevant Date except to the extent that the Holder of such Note would have been entitled to such Additional Amounts, on surrender of such Note for payment on the last day of such period of 30 days;

(iii)    in respect of any tax, duty, assessment or other governmental charge imposed on a Note presented for payment by or on behalf of a Holder where the Holder or beneficial owner would have been able to avoid that withholding or deduction by presenting the relevant Note to another paying agent in a member state of the European Union;

(iv)    in respect of any tax, duty, assessment or other governmental charge imposed or withheld pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), as of the date of this Indenture (or any amended or successor version), current or future U.S. Treasury Regulations issued thereunder or any official interpretation thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code;

(v)    to, or to a third party on behalf of, a Holder where the Holder or beneficial owner is liable for any present or future taxes, duties, assessments or other governmental charges by reason of the Holder’s or beneficial owner’s failure to comply with any certification, identification or other reporting requirement concerning nationality, residence, identity or connection with the Relevant Jurisdiction, if (1) compliance is required by the Relevant Jurisdiction, as a precondition to, exemption from, or reduction in the rate of, the tax, duty, assessment or other governmental charge and (2) the Company has given at least 30 days’ notice that Holders or beneficial owners will be required to provide such certification, identification or other requirement;

(vi)    in respect of any estate, inheritance, gift, sales, transfer, capital gains, excise or personal property or similar tax, duty, assessment or governmental charge;

(vii)    in respect of any tax, duty, assessment or other governmental charge that is payable otherwise than by deduction or withholding from payments of principal of or interest on the Note or by direct payment by the Company in respect of claims made against the Company; or

(viii)    in respect of any combination of the above.

33

(b)    No Additional Amounts shall be paid with respect to any payment on a Note to a Holder who is a fiduciary, a partnership, a limited liability company or other than the sole beneficial owner of that payment to the extent that payment would be required by the laws of the Relevant Jurisdiction to be included in the income, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a member of that partnership, an interest holder in a limited liability company or a beneficial owner who would not have been entitled to the Additional Amounts had that beneficiary, settlor, member or beneficial owner been the Holder. Except as specifically provided above, the Company shall not be required to make any payment with respect to any tax, duty, assessment or governmental charge imposed by any government or political subdivision or taxing authority thereof or therein.

(c)    In the event that Additional Amounts actually paid with respect to the Notes described above are based on rates of deduction or withholding of taxes in excess of the appropriate rate applicable to the Holder of such Notes, and, as a result thereof the Holder is entitled to make a claim for a refund or credit of the excess from the authority imposing the withholding tax, then the Holder shall, by accepting the Notes, be deemed to have assigned and transferred all right, title, and interest to any such claim for a refund or credit of such excess to the Company. However, by making such assignment, the Holder makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto.

(d)    Any reference in this Indenture or the Notes to principal, interest or any other amount payable in respect of the Notes by the Company will be deemed also to refer to any Additional Amount that may be payable with respect to that amount under the obligations referred to in this Section, unless the context requires otherwise.

Section 3.02    Optional Redemption with a Make-Whole Premium.

(a)    Prior to September 20, 2020, the Company may, at its option, redeem all of the Notes at any time or part of the Notes from time to time at a Redemption Price equal to 100% of the principal amount of the Notes plus the Applicable Premium as of, and accrued and unpaid interest to, but excluding, the Redemption Date (subject to the right of Holders on the relevant Record Date to receive interest due on the relevant Interest Payment Date).

(b)    Any notice to Holders pursuant to Section 3.02(a) shall specify the Redemption Date, the CUSIP or ISIN numbers, the interest to be paid on the Redemption Date, and shall be accompanied by an Officers’ Certificate of the Company as to the estimated Applicable Premium due in connection with such redemption (calculated as if the date of such notice were the Redemption Date), setting forth the details for such computation. Two Business Days prior to such redemption, the Company shall deliver to the Trustee and each Holder an Officers’ Certificate specifying the calculation of the Applicable Premium as of the Redemption Date. In the event the Company shall incorrectly compute the Applicable Premium payable in connection with the Notes to be redeemed, the Holders shall not be bound by such incorrect computation, but instead, shall be entitled to receive an amount equal to the correct Applicable Premium computed in compliance with the terms of this Indenture.

34

On and after September 20, 2020, the Company may, at its option, redeem all of the Notes at any time or part of the Notes from time to time at the following Redemption Prices (expressed as a percentage of principal amount), plus accrued and unpaid interest to, but excluding, the Redemption Date (subject to the right of Holders on the relevant Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period commencing on September 20 of the years set forth below:

(ii)    the redemption occurs within 90 days of the date of the closing of such sale of Equity Interests.

(b)    Notice of any redemption upon any sale of Equity Interests may be given prior to the completion thereof, and any such redemption or notice may, at the Company’s discretion, be subject to one or more condition precedent, including, but not limited to, completion of the related sale.

Section 3.05    Redemption for Taxation Reasons . If as a result of any change in or amendment to the laws (or any applicable treaties, or any rules or regulations thereunder) of a Relevant Jurisdiction, or any amendment to or change in an official interpretation, administration or application of such laws, treaties, rules, or regulations (including a holding by a court of competent jurisdiction), which change or amendment becomes effective or, in the case of a change in official position, is announced on or after the later of the Issue Date or the date a Relevant Jurisdiction becomes a Relevant Jurisdiction, (i) the Company has or will become obligated to pay any Additional Amounts, as described in Section 3.01, the Company may, at its option, redeem all, but not less than all, of the Notes, at a Redemption Price equal to 100% of their principal amount, together with interest and Additional Amounts, if any, accrued to, but excluding, the date fixed for redemption, upon publication of irrevocable notice of redemption not fewer than 30 days nor more than 90 days prior to the date fixed for redemption.

35

Section 3.06    Method, Effect and Notice of Redemption . (a) The election of the Company to redeem the Notes pursuant to Section 3.02 through Section 3.04 shall be evidenced by a Board Resolution. In the event that the Company or any successor is required to redeem, or elects for the Company to so redeem, the Notes, it will deliver to the Trustee: (i) a certificate, signed in the name of the Company by two of its Officers or by its attorney-in-fact in accordance with its bylaws or those of any successor, as the case may be, stating that the Company or any successor, as the case may be, entitled to redeem the Notes pursuant to their terms and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Company or any successor, as the case may be, to so redeem have occurred or been satisfied; and (ii) in respect of a redemption pursuant to Section 3.05, an Opinion of Counsel to the effect that the Company or any successor has or will become obligated to pay Additional Amounts in excess of the Additional Amounts as a result of the change or amendment, that the Company or any successor, as the case may be, cannot avoid payment of such excess Additional Amounts by taking reasonable measures available to it and that all governmental requirements necessary for the Company or any successor to effect the redemption have been complied with. In relation to redemptions pursuant to Section 3.02 through Section 3.04 only, in the event that less than all of the Notes are to be redeemed at any time, selection of Notes for redemption will be made by the Trustee on a pro rata basis or by lot (or, in the case of Notes issued in global form, in accordance with the procedures of DTC), unless otherwise required by law. If Notes are redeemed in part, the remaining outstanding principal amount (including any Additional Notes, but excluding any Notes held by the Company or any of its Affiliates) must be at least equal to U.S.$100.0 million. A new Note in a principal amount equal to the unredeemed portion thereof, if any, will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a global note will be made, as appropriate).

At least five days prior to the date when the notice of redemption is sent to the Holders of the Notes (unless a shorter notice period shall be acceptable to the Trustee), the Company shall notify the Trustee in writing of such proposed redemption date and the principal amount of the Notes to be redeemed. In relation to redemptions of Notes pursuant to Section 3.02 through Section 3.04, if the Notes are to be redeemed in part only, the notice of redemption will state the portion of the principal amount thereof to be redeemed.

Section 4.05    Compliance with Applicable Laws. The Company shall, and shall cause any Restricted Subsidiary to, comply with all laws applicable to it or its property, except where the failure to do so, individually or in the aggregate, would not reasonably be expected to result in a (i) material adverse effect on the condition (financial or otherwise), business, properties or results of operations of the Company, its Restricted Subsidiaries and any Raízen Significant Entity taken as a whole and (ii) material adverse effect on the ability of the Company to perform its respective obligations under this Indenture.

In addition, as set forth in the definitions of “Adjusted EBITDA” and “Adjusted Net Debt” in Section 1.01, each of the Logistics Excluded Entities shall be excluded from the calculation of each of Adjusted EBITDA and Adjusted Net Debt for purposes of the calculation of the Net Debt to EBITDA Ratio.

(b)    Notwithstanding the foregoing, the Company, and to the extent provided below, any Restricted Subsidiary may Incur the following (“Permitted Debt”):

(c)    Notwithstanding anything to the contrary in this Section, the maximum amount of Debt that the Company and its Restricted Subsidiaries may Incur pursuant to this Section shall not be deemed to be exceeded, with respect to any outstanding Debt, solely as a result of fluctuations in the exchange rate of currencies.

(d)    For purposes of determining compliance with this Section, in the event that any proposed Debt meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xvii) of Section 4.07(b), or is entitled to be Incurred pursuant to Section 4.07(a), the Company and its Restricted Subsidiaries will be permitted to classify such item of Debt at the time of its Incurrence in any manner that complies with this Section or to later reclassify all or a portion of such item of Debt.

(g)    For the purposes of determining the Net Debt to EBITDA Ratio in paragraph (a) above, the U.S. Dollar-equivalent principal amount of Debt denominated in a non-U.S. currency or the Brazilian-reais equivalent principal amount of Debt denominated in a non-Brazilian currency shall be calculated based on the relevant currency exchange rate determined on the date of Incurrence to the extent the Debt was hedged for foreign exchange rate fluctuations. For purposes of determining compliance with any U.S. Dollar-denominated restriction on the Incurrence of Debt, the U.S. Dollar-equivalent principal amount of Debt denominated in a non U.S. currency shall be calculated based on the relevant currency exchange rate determined on the date of Incurrence, in the case of term Debt, or first committed, in the case of revolving credit Debt; provided that if such Debt is Incurred to refinance other Debt denominated in a non U.S. currency, and such refinancing would cause the applicable U.S. Dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. Dollar-denominated restriction will be deemed not to have been exceeded so long as the principal amount of such Permitted Refinancing Debt does not exceed the principal amount of such Debt being refinanced. The principal amount of any Debt Incurred to refinance other Debt, if Incurred in a different currency from the Debt being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Debt is denominated calculated based on the relevant currency exchange rates as calculated in the first sentence of this Section 4.07(g).

(4)    the amount by which Debt of the Company or any of its Restricted Subsidiaries is reduced on the Company’s balance sheet or the balance sheet of such Restricted Subsidiary, in each case, upon the conversion or exchange (including by means of a subscription) (other than by the Company or any of its Restricted Subsidiaries) subsequent to the Issue Date of any such Debt for Equity Interests (other than Disqualified Equity Interests) of the Company (less the amount of any cash or the fair market value of any other property distributed by the Company or any of its Restricted Subsidiaries upon such conversion or exchange).

(x)    required pursuant to this Indenture.

Section 4.12    Repurchase of Notes Upon a Change of Control. Not later than 30 days following a Change of Control that results in a Rating Decline, the Company shall make an Offer to Purchase all outstanding Notes at a purchase price equal to 101% of the principal amount plus accrued interest to the date of purchase.

Section 4.13    Limitation on Asset Sales. The Company will not, and will not permit any Restricted Subsidiary to, make any Asset Sale unless the following conditions are met:

(i)    The Asset Sale is for fair market value, as determined in good faith by the Board of Directors.

(ii)    At least 75% of the consideration consists of cash or Cash Equivalents. (For purposes of this clause (ii), the assumption by the purchasers of Debt or other obligations (other than Subordinated Debt) of the Company or a Restricted Subsidiary pursuant to a customary novation agreement, and instruments or securities received from the purchasers that are promptly, but in any event within 90 days of the closing, converted by the Company to cash, to the extent of the cash actually so received, shall be considered cash received at closing.)

(iii)    Within 360 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Net Cash Proceeds may be used (each, a “Permitted Reinvestment”):

51

(A)    to permanently repay Debt other than Subordinated Debt of the Company or any Restricted Subsidiary (and in the case of a revolving credit, permanently reduce the commitment thereunder by such amount), in each case owing to a Person other than the Company or any Restricted Subsidiary,

(B)    to acquire or invest in (or within such 360-day period in this clause (iii) the Company’s Board of Directors shall have made a good faith determination to acquire or invest, which acquisition or investment shall be consummated prior to the second anniversary of such Asset Sale) (i) all or substantially all of the assets of a Permitted Business, (ii) a majority of the Voting Stock of another Person that thereupon becomes a Restricted Subsidiary engaged in a Permitted Business, or to make capital expenditures or otherwise acquire long-term assets that are to be used in a Permitted Business or (iii) a Permitted Business Investment; or

(C)    to acquire Productive Assets for the Company or any of its Restricted Subsidiaries;

provided that pending the final application of any such Net Cash Proceeds in accordance with this clause (iii), the Company or such Restricted Subsidiary may temporarily reduce Debt or otherwise invest such Net Cash Proceeds in any manner not prohibited by this Indenture.

(iv)    Notwithstanding clauses (i) to (iii) above, the Company and its Restricted Subsidiaries will be permitted to consummate an Asset Sale without complying with such clauses to the extent:

(A)    at least 75% of the consideration for such Asset Sale constitutes Productive Assets, cash, Cash Equivalents and/or Marketable Securities; and

(B)    the Asset Sale is for fair market value, as determined in good faith by the Board of Directors;

provided that any consideration not constituting Productive Assets received by the Company or any Restricted Subsidiary in connection with any Asset Sale permitted to be consummated under this clause shall be applied (in the case of cash, Cash Equivalents and Marketable Securities within 360 days after the receipt thereof) in accordance with Section 4.13(iii) above.

(v)    The Net Cash Proceeds of an Asset Sale not applied pursuant to Section 4.13(iii) within 360 days of the Asset Sale constitute “Excess Proceeds.” Excess Proceeds of less than U.S.$50.0 million (or the equivalent thereof at the time of determination) will be carried forward and accumulated. When accumulated Excess Proceeds equals or exceeds such amount, the Company must, within 30 days, make an Offer to Purchase Notes having a principal amount equal to:

(A)    accumulated Excess Proceeds, multiplied by

52

(B)    a fraction (x) the numerator of which is equal to the outstanding principal amount of the Notes and (y) the denominator of which is equal to the outstanding principal amount of the Notes and all pari passu Debt similarly required to be repaid, redeemed or tendered for in connection with the Asset Sale, rounded down to the nearest U.S.$1,000.

The purchase price for the Notes will be 100% of the principal amount plus accrued interest to the date of purchase. If the Offer to Purchase is for less than all of the outstanding Notes and Notes in an aggregate principal amount in excess of the purchase amount are tendered and not withdrawn pursuant to the offer, the Company will purchase Notes having an aggregate principal amount equal to the purchase amount on a pro rata basis, with adjustments so that only Notes in multiples of U.S.$1,000 principal amount will be purchased, provided that after a purchase from a Holder in part, such Holder shall hold U.S.$200,000 in principal amount of Notes or a multiple of U.S.$1,000 in excess thereof. Any failure to obtain such consents and approvals will constitute an Event of Default. Upon completion of the Offer to Purchase, Excess Proceeds will be reset at zero.

Section 4.14    Limitation on Transactions with Shareholders and Affiliates. (a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, enter into, renew or extend any transaction or arrangement including the purchase, sale, lease or exchange of property or assets, or the rendering of any service with (x) any of its shareholders holding 10% or more of any class of Capital Stock of the Company or (y) any Affiliate of the Company or any Restricted Subsidiary (a “Related Party Transaction”), except upon terms no less favorable to the Company or the Restricted Subsidiary than could be obtained in a comparable arm’s-length transaction with a Person that is not an Affiliate of the Company.

(b)    In any Related Party Transaction or series of Related Party Transactions with an aggregate value in excess of U.S.$25.0 million (or the equivalent thereof at the time of determination), the Company must first deliver to the Trustee a certificate from the Company’s Chief Financial Officer or Chief Executive Officer to the effect that such transaction or series of related transactions are on terms no less favorable to the Company or such Restricted Subsidiary than could be obtained in a comparable arm’s length transaction and is otherwise compliant with the terms of this Indenture.

(c)    The foregoing paragraphs of this Section 4.14 do not apply to

(i)    any transaction between the Company and any Restricted Subsidiary or between Restricted Subsidiaries and the Company;

(ii)    the payment of reasonable and customary regular fees to directors of the Company who are not employees of the Company;

(iii)    any Restricted Payments of a type described in Section 4.08(a)(i) or Section 4.08(a)(ii) if permitted by that covenant;

(iv)    any issuance or sale of Equity Interests (other than Disqualified Stock);

53

(v)    transactions or payments pursuant to any employee, officer or director compensation or benefit plans, customary indemnifications or arrangements entered into in the ordinary course of business;

(vi)    transactions pursuant to agreements in effect on the Issue Date and described in the Offering Memorandum, as amended, modified or replaced from time to time so long as the amended, modified or new agreements, taken as a whole, are no less favorable to the Company and its Restricted Subsidiaries than those in effect on the date of this Indenture;

(vii)    any Sale Leaseback Transaction otherwise permitted under Section 4.10 if such transaction is on market terms;

(viii)    any advance, loan or other extension of credit (or guarantee thereof) in connection with the use of the proceeds of the Notes (including any Additional Notes) as well as additional loans outstanding from the Company or any of its Restricted Subsidiaries to an Affiliate to the extent that any such advance, loan or other extension of credit (i) has a Stated Maturity that is prior to the Stated Maturity of the Notes and (ii) is on market terms;

(ix)    (A) transactions with customers, clients, distributors, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of business and on market terms, or (B) transactions with joint ventures or other similar arrangements entered into in the ordinary course of business, on market terms and consistent with past practice or industry norms;

(x)    the Joint Venture and any transactions or provision of services related thereto;

(xi)    the provision of administrative services to any joint venture or Unrestricted Subsidiary on substantially the same terms provided to or by Restricted Subsidiaries;

(xii)    the Lubricant Disposal; and

(xiii)    the Radar Disposal.

Section 4.15    Maintenance of Books and Records. The Company shall keep, and shall cause any Restricted Subsidiary to keep, proper books of record and account in which, true and correct entries, in all material respects, shall be made of dealings and transactions in relation to its business and activities except where the failure to do so would not reasonably be expected to result in a material adverse effect on the ability of the Company to perform its respective obligations under this Indenture.

Section 4.16    Reports to the Trustee

(a)    The Company will provide the Trustee with the following reports (and will also provide the Trustee with sufficient copies, as required, of the following reports referred to in clauses (i), (ii) and (iv) below for distribution, at the expense of the Company, to all Holders of Notes):

54

(ii)    an English language version of its unaudited quarterly financial statements prepared in accordance with IFRS promptly upon such financial statements becoming available but not later than 60 days after the close of each fiscal quarter (other than the last fiscal quarter of its fiscal year);

(iii)    simultaneously with the delivery of the financial statements referred to in clause (a) above, an Officers’ Certificate stating whether an Event of Default exists on the date of such certificate and, if an Event of Default exists, setting forth the details thereof and the action which the Company is taking or proposes to take with respect thereto;

(iv)    without duplication, English language versions or summaries of such other reports or notices as may be filed or submitted by (and promptly after filing or submission by) the Company with any stock exchange on which the Notes may be listed (in each case, to the extent that any such report or notice is generally available to its security holders);

(v)    as soon as practicable and in any event within 30 calendar days after any director or executive officer of the Company becomes aware of the existence of an Event of Default, an Officers’ Certificate setting forth the details thereof and the action which the Company is taking or proposes to take with respect thereto; and

(b)    If the Company makes available the reports described in clauses (i) or (ii) or (iv) on the Company’s website and notifies the Trustee in writing thereof, it will be deemed to have satisfied the reporting requirement set forth in such applicable clause.

(c)    Delivery of the above reports to the Trustee is for informational purposes only and the Trustee’s receipt of such reports shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants in this Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates), provided that the Trustee shall have no obligation whatsoever to determine whether such information, documents or reports have been so made available.

(d)    For so long as the Notes are “restricted securities” within the meaning of Rule 144A(a)(3) under the Securities Act, the Company will furnish upon request to any Holder of a Note, or to any prospective purchasers designated by such Holder of Notes, financial and other information described in paragraph (d)(4) of Rule 144A with respect to the Company.

Section 4.17    Ranking. The Company shall ensure that its obligations under this Indenture and the Notes will at all times constitute direct and unconditional obligations of the Company, ranking at all times at least pari passu in priority of payment, in right of security and in all other respects among themselves and with all other Debt of such Person, except to the extent any such other Debt ranks above such obligations by reason of Liens permitted under Section 4.09.

55

Section 4.18    Paying Agent and Transfer Agent

(a)    The Company agrees, for the benefit of the Holders from time to time of the Notes, that, until all of the Notes are no longer outstanding or until moneys for the payment of all of the principal of and interest on all Notes (and Additional Amounts, if any) shall have been made available at an office of the Principal Paying Agent, and shall have been returned to the Company as provided herein, whichever occurs earlier, there shall at all times be a Principal Paying Agent and Transfer Agent hereunder. The Principal Paying Agent and the Transfer Agent shall have the powers and authority granted to and conferred upon them herein and in the Notes.

(b)    The Company hereby initially appoints the Paying Agents and Transfer Agent defined in this Indenture as such. The Principal Paying Agent shall arrange with the Paying Agents for the payment, from funds furnished by the Company to the Principal Paying Agent pursuant to this Indenture, of the principal of and interest on the Notes (and Additional Amounts, if any, with respect to the Notes).

Section 4.19    Covenant Suspension. From any date (the “Suspension Date”) and during any time that:

(a)    the Notes have an Investment Grade rating from any two Rating Agencies, and no Event of Default has occurred and is continuing, the Company and its Restricted Subsidiaries will not be subject to Sections 4.07, 4.08, 4.10, 4.11, 4.13, 4.14 (collectively, the “Suspended Covenants”).

In the event that the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) the Notes cease to have an Investment Grade Rating from any two Rating Agencies, then the Company and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants. The period of time between the Suspension Date and the Reversion Date is referred to as the “Suspension Period.” Notwithstanding that the Suspended Covenants may be reinstated, no Event of Default will be deemed to have occurred as a result of a failure to comply with any of the Suspended Covenants during the Suspension Period (or upon termination of the Suspension Period or after that time based solely on events that occurred during the Suspension Period).

On the Reversion Date, all Debt Incurred during the Suspension Period will be classified to have been Incurred pursuant to Section 4.07(a) or clauses (i) through (xvii) of Section 4.07(b) (to the extent such Debt would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to the Debt Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Debt would not be permitted to be Incurred pursuant to Section 4.07, such Debt will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.07(b)(vii). The Company will give the Trustee prompt written notification upon the occurrence of a covenant suspension or any Reversion Date.

(b)    Notwithstanding the foregoing, this covenant will not apply to any sale, conveyance, transfer, or disposition resulting from the exercise of any put or call options (an “Option Exercise”) by Cosan S.A. Indústria e Comércio, Shell or any other party to the definitive agreements to the Joint Venture if either (i) such Option Exercise does not result in a Rating Decline or (ii) within 360 days after the receipt of any Net Cash Proceeds from such Option Exercise, Cosan S.A.

Nothing in this Indenture will be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

61

This Section 6.11 does not apply to a suit by the Trustee, suit by a Holder to enforce payment of principal of or interest on any Note on the respective due dates pursuant to this Section 6.11, or a suit by Holders of more than 10% in principal amount of the outstanding Notes.

Section 6.12    Rights and Remedies Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders under this Indenture is intended to be exclusive of any other right or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in addition to every other right and remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or exercise of any other right or remedy.

Section 6.13    Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.14    Waiver of Stay, Extension or Usury Laws. The Company covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of, or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture. The Company hereby expressly waives, to the extent that it may lawfully do so, all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 7.06    Compensation and Indemnity. (a) The Company will pay the Trustee and the Agents compensation as agreed upon in writing between the Company and the Trustee and the Agents for their services. The compensation of the Trustee is not limited by any law on compensation of a Trustee of an express trust. The Company will reimburse the Trustee and Agents upon request for all reasonable and documented out-of-pocket expenses, disbursements and advances incurred or made by the Trustee and the Agents, including the compensation and reasonable and documented expenses of the Trustee’s and the Agents’ agents and counsel.

66

(b)    The Company will indemnify the Trustee and the Agents for, and hold it harmless against, any loss or liability or expense (including, without limitation, the reasonable and documented fees and expenses of its legal counsel) incurred by it without gross negligence or willful misconduct on its part arising out of or in connection with the acceptance or administration of this Indenture by it, the performance of its duties under this Indenture and the Notes and the exercise of its rights hereunder, including the costs and expenses (legal or otherwise) of defending itself against any claim or liability and of complying with any process served upon it or any of its officers in connection with the exercise or performance of any of its powers, rights or duties under this Indenture and the Notes.

(d)    If the Trustee incurs expenses or renders services in connection with an Event of Default as specified herein, the expenses (including, without limitation, the reasonable and documented charges and expenses of its legal counsel per jurisdiction) and the compensation for the services are intended to constitute expenses of administration under any applicable bankruptcy, reorganization, insolvency or similar law now or hereafter in effect.

The Company also agrees to indemnify each of the Agents for, and to hold each of them harmless against, any loss, liability or expense (including, without limitation, the reasonable and documented fees and expenses of its legal counsel) incurred out of or in connection with its acting as Agent of the Company hereunder, except to the extent such loss, liability or expense results from such Agent’s own gross negligence or willful misconduct. The obligations of the Company under this subsection (i) shall survive the payment of the Notes and the resignation or removal of any Agent and/or the termination of this Indenture;

(ii)    In acting under this Indenture and in connection with the Notes, the Agents are each acting solely as agent of the Company and do not assume any obligation towards or relationship of agency or trust for or with any of the Holders except that all funds held by a Paying Agent for the payment of the principal of, interest on (and Additional Amounts, if any, with respect to) the Notes, shall be held in trust by it and applied as set forth herein and in the Notes, but need not be segregated from other funds held by it, except as required by law;

(iii)    No Agent shall be under any liability for interest on any moneys or to invest any moneys, received by it pursuant to any of the provisions of this Indenture or the Notes;

No Agent shall be under any obligation to take any action hereunder which may tend to involve it in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured to it; and

(vi)    Unless otherwise specifically provided herein or in the Notes, any order, certificate, notice, request, direction or other communication from the Company made or given under any provision of this Indenture shall be sufficient if signed by an authorized Officer or any duly authorized attorney-in-fact.

69

(b)    Any Agent may at any time resign by giving written notice of its resignation mailed to the Company specifying the date on which its resignation shall become effective; provided that such date shall be at least 60 days after the date on which such notice is given unless the Company agrees to accept less notice. Upon receiving such notice of resignation, the Company shall promptly appoint a successor Agent, qualified as aforesaid, by written instrument in duplicate signed on behalf of the Company, one copy of which shall be delivered to the resigning Agent and one copy to the successor Agent. Such resignation shall become effective upon the earlier of (i) the effective date of such resignation or (ii) the acceptance of appointment by the successor Agent as provided in Section 7.11(c). The Company may, at any time and for any reason, and shall, upon any event set forth in the next succeeding sentence, remove an Agent and appoint a successor Agent, qualified as aforesaid, by written instrument in duplicate signed on behalf of the Company, one copy of which shall be delivered to the Agent being removed and one copy to the successor Agent. An Agent shall be removed as aforesaid if it shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of such Agent or of its property shall be appointed, or any public officer shall take charge or control of it or of its property or affairs for the purpose of rehabilitation, conservation or liquidation.

Upon its resignation or removal, the Agent shall be entitled to the payment by the Company of its compensation for the services rendered hereunder and to the reimbursement of all reasonable out-of-pocket expenses incurred in connection with the services rendered by it hereunder (including, without limitation, the reasonable and documented fees and expenses of its legal counsel).

(c)    Any successor Agent appointed as provided in Section 7.11(b) shall execute and deliver to its predecessor and to the Company an instrument accepting such appointment hereunder, and thereupon such successor Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Paying Agent or Transfer Agent hereunder, and such predecessor, upon payment of its compensation and reasonable and documented out-of-pocket expenses (including, without limitation, the reasonable and documented fees and expenses of its legal counsel) then unpaid, shall pay over to such successor agent all moneys or other property at the time held by it hereunder, if any.

(d)    Any corporation or bank into which any Agent may be merged or converted, or with which any Agent may be consolidated, or any corporation or bank resulting from any merger, conversion or consolidation to which an Agent shall be a party, or any corporation or bank succeeding to all or substantially all of the agency business of the Agent (including this transaction) shall be the successor to such Agent hereunder (provided that such corporation or bank shall be qualified as aforesaid) without the execution or filing of any paper or any further act on the part of any of the parties hereto.

(e)    The Company undertakes to indemnify any Paying Agent against all losses, liabilities, including any and all tax liabilities, which, for the avoidance of doubt, shall include Brazilian taxes and associated penalties, costs, claims, actions, damages, expenses or demands which any of them may incur or which may be made against any of them as a result of or in connection with the appointment of or the exercise of the powers and duties by the Paying Agent under this Indenture except as may result from its own gross negligence. The Paying Agent shall take all reasonable measures to minimize any such tax liabilities, as instructed in writing by the Company, the Trustee or a Holder.

70

(f)    The Company acknowledges that the Principal Paying Agent makes no representations as to the interpretation or characterization of the transactions herein for tax or any other purpose, in any jurisdiction.

(h)    Each payment in full of principal, redemption amount, Additional Amounts and/or interest payable in respect of any Note made by or on behalf of the Company to or to the order of the Principal Paying Agent in the manner specified herein on the date due shall be valid and effective to satisfy and discharge the obligation of the Company to make payment of principal, redemption amount, Additional Amounts and/or interest payable under the Notes on such date, provided, however, that the liability of the Principal Paying Agent hereunder shall not exceed any amounts paid to it by the Company or held by it, on behalf of the Holders under this Indenture; and provided further that, in the event that there is a default by the Principal Paying Agent in any payment of principal, redemption amount, Additional Amounts and/or interest in respect of any Note, the Company shall pay on demand such further amounts as will result in receipt by the Holder of such amounts as would have been received by it had no such default occurred.

(a) Except as otherwise provided in Section 6.02 or Section 9.02(b), the Company and the Trustee may amend this Indenture and the Notes with the written consent of the Holders of a majority in principal amount of the outstanding Notes, and the Holders of a majority in principal amount of the outstanding Notes may waive future compliance by the Company with any provision of this Indenture or the Notes.

74

(b)    Notwithstanding the provisions of Section 9.02(a), without the consent of each Holder affected, an amendment or waiver may not:

(i)    reduce the principal amount of or change the Stated Maturity of any installment of principal of any Note;

(ii)    reduce the rate of or change the Stated Maturity of any interest payment on any Note;

(iii)    reduce the amount payable upon the redemption of any Note in respect of an optional redemption, the times at which any Note may be redeemed or, once notice of redemption has been given, the time at which the Note must thereupon be redeemed;

(iv)    after the time an Offer to Purchase is required to have been made, reduce the purchase amount or purchase price, or extend the latest expiration date or purchase date thereunder;

(v)    make any Note payable in currency other than that stated in the Note or at a place of payment other than that stated in the Notes;

(vi)    impair the contractual right as forth in this Indenture of any Holder to receive any principal payment or interest payment on such Holder’s Notes, on or after the Stated Maturity thereof, or to institute suit for the enforcement of any such payment; or

(vii)    make any change in the percentage of the principal amount of the Notes required for amendments or waivers.

(c)    It is not necessary for Holders to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if their consent approves the substance thereof.

(d)    An amendment, supplement or waiver under this Section will become effective on receipt by the Trustee of written consents from the Holders of the requisite percentage in principal amount of the outstanding Notes.

Section 9.03    Effect of Consent. (a) After an amendment, supplement or waiver becomes effective, it will bind every Holder unless it is of the type requiring the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting Holder.

(b)    If an amendment, supplement or waiver changes the terms of a Note, the Trustee may request the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of the changed terms on the Note and return it to the Holder, or exchange it for a new Note that reflects the changed terms. The Trustee may also place an appropriate notation on any Note thereafter authenticated. However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion.

75

Section 9.04    Trustee’s Rights and Obligations. The Trustee shall receive, and will be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of any amendment, supplement or waiver is authorized or permitted by this Indenture. If the Trustee has received such Officers’ Certificate or Opinion of Counsel, it shall sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver that affects the Trustee’s own rights, duties or immunities under this Indenture.

Such notice shall identify the name of such agent for process and the address of such agent for process in the Borough of Manhattan, The City of New York, State of New York. Upon the written request of any Holder, the Trustee shall deliver such information to such Holder. Notwithstanding the foregoing, there shall, at all times, be at least one agent for service of process for the Company appointed and acting in accordance with this Section 10.07.

79

(c)    To the extent that the Company has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, the Company hereby irrevocably waives such immunity in respect of their obligations under this Indenture and the Notes, to the extent permitted by law.

Section 10.08    Judgment Currency

(a)    U.S. Dollars are the sole currency of account and payment for all sums due and payable by the Company under this Indenture and the Notes. If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum due hereunder in U.S. Dollars into another currency, the Company will agree, to the fullest extent that they may legally and effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Trustee determines a Person could purchase U.S. Dollars with such other currency in New York, New York, on the Business Day immediately preceding the day on which final judgment is given.

(b)    The obligation of the Company in respect of any sum due to any Holder or the Trustee in U.S. Dollars shall, to the extent permitted by applicable law, notwithstanding any judgment in a currency other than U.S. Dollars, be discharged only to the extent that on the Business Day following receipt of any sum adjudged to be so due in the judgment currency such Holder or Trustee may in accordance with normal banking procedures purchase U.S. Dollars in the amount originally due to such Person with the judgment currency. If the amount of U.S. Dollars so purchased is less than the sum originally due to such Person, the Company agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Person against the resulting loss; and if the amount of U.S. Dollars so purchased is greater than the sum originally due to such Person, such Person will, by accepting a Note, be deemed to have agreed to repay such excess.

Section 10.09    No Adverse Interpretation of Other Agreements. This Indenture may not be used to interpret another indenture or loan or debt agreement of the Company or any Subsidiary of the Company, and no such indenture or loan or debt agreement may be used to interpret this Indenture.

80

Section 10.11    Duplicate Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

Section 10.12    Separability. In case any provision in this Indenture or in the Notes is invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby.

Section 10.13    Table of Contents and Headings. The Table of Contents, Cross-Reference Table and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and in no way modify or restrict any of the terms and provisions of this Indenture.

Section 10.14    No Liability of Directors, Officers, Employees, Incorporators, Members and Stockholders. No director, officer, employee, incorporator, member or stockholder of the Company, as such, will have any liability for any obligations of the Company under the Notes or this Indenture or for any claim based on, in respect of, or by reason of, such obligations. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. This waiver may not be effective to waive liabilities under U.S. securities laws and it is the view of the Commission that such a waiver is against public policy.

Section 10.15    USA PATRIOT Act. In order to comply with the laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including, without limitation, those relating to the funding of terrorist activities and money laundering, including Section 326 of the USA PATRIOT Act of the United States (“Applicable Law”), the Trustee and Agents are required to obtain, verify, record and update certain information relating to individuals and entities which maintain a business relationship with the Trustee and Agents. Accordingly, each of the parties agree to provide to the Trustee and Agents, upon their request from time to time such identifying information and documentation as may be available for such party in order to enable the Trustee and Agents to comply with Applicable Law.

Interest will be payable semi-annually (to the holders of record of the Notes at the close of business on March 18 or September 18 immediately preceding the corresponding interest payment date) on each Interest Payment Date, commencing March 20, 2018.

Interest on this Note will accrue from the most recent date to which interest has been paid on this Note (or, if there is no existing default in the payment of interest and if this Note is authenticated between a regular record date and the next Interest Payment Date, from such Interest Payment Date) or, if no interest has been paid, from the Issue Date. Interest will be computed in the basis of a 360-day year of twelve 30-day months.

Basis of preparation

2 Basis of preparation

2.1 Statement of compliance

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

The relevant information of the financial statements, and only them, are being evidenced and correspond to those used by management in its management.

These consolidated financial statements were authorized for issue by the Board of Directors on February 22, 2018.

Certain amounts of the comparative balances, in the statements of profit or loss, statements of cash flows and in the notes 9, 11, 12, 13, 17, 18, 20, 22, 23 and 31, were reclassified to improve the level of details of disclosures in the financial statements. These reclassifications had inconsequential impacts on the Company´s financial statements.

2.2 Functional and presentation currency

The consolidated financial statements are presented in Brazilian Reais. However, the functional currency of Cosan Limited is the U.S. Dollar (U.S.$). The Brazilian Real is the functional currency of Cosan S.A., Cosan Logística, its subsidiaries and joint ventures, located in Brazil, as it is the currency of the primary economic environment in which they operate, generate and expend cash. The main functional currency for the subsidiaries located outside Brazil is U.S. Dollar or the Pound Sterling (GBP).

2.3 Use of judgments and estimates

The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue and expenses at the end of the reporting period. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized prospectively. Information about critical judgments, assumptions and estimation uncertainties in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes:

• Notes 15 and 16 – Property, plant and equipment and intangible assets

The Company performs annually a review of impairment indicators for intangible assets with defined useful lives and property, plant and equipment. Also, an impairment test is undertaken for goodwill and intangible assets with indefinite useful lives. Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs to sell and its value in use. The key assumptions used to determine the recoverable amount of the different cash generating units to which goodwill is allocated are explained in note 16.

The subsidiary Comgás has an agreement for the public concession of gas distribution service which the Conceding Authority controls what services must be rendered and what prices will be applied, as well as included significant interest in the infrastructure at the end of the concession. This concession agreement represents the right to charge customers for the supply of gas during the effective period of the agreement. Therefore, the Company recognizes this right as intangible assets.

Thus, the infrastructure construction necessary for gas distribution is considered a service to the Grantor and the related revenue is recognized at fair value. Financing costs directly related to construction are also capitalized.

The Company does not recognize a margin on the infrastructure construction.

Subject to approval of the Granting Authority, the Company may request only once the extension of the distribution services for another 20 years. When the concession is terminated, the assets linked to the rendering of gas distribution services will be returned to the Granting Authority, and the Company will be entitled to receive an indemnity to be determined based on assessments and evaluations to be calculated at the time. Currently the figures for compensation are not predetermined or determinable, which is why the Company did not apply the bifurcated model for the accounting of financial assets.

The amortization of intangible assets reflects the pattern expected for the utilization of the future economic benefits by the Company, which corresponds to the useful lives of the assets comprising the infrastructure consonant to the São Paulo State Sanitation and Energy Regulatory Agency (“ARSESP”) provisions, as disclosed in note 16.

The amortization of the intangible assets is discontinued when the related asset is fully used or written off, and no longer is included in the calculation basis of the tariff for the rendering of the concession services, whichever occurs first.

The subsidiary Rumo has a concession rights generated in the business combination of ALL, which was fully allocated to Rumo Malha Norte concession and amortized on the straight-line method based on estimated useful lives of intangible assets, from the date on which these are available for use.

• Note 18 – Operating lease commitments

The Company contracted commercial leases of locomotives and wagons. The classification of the lease as operational or financial is determined based on an evaluation of the terms and conditions of the contracts. The Company identified the cases in which it assumes substantially all the risks and benefits of ownership of the said assets, recording such cases as a financial lease.

• Note 23 – Income taxes and social contribution

A deferred tax asset is recognized for loss carryforwards to the extent that it is probable that future taxable income will be generated to realize such losses. Significant judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the timing and the level of future taxable income together with future tax planning strategies.

• Other non-current assets

The subsidiary Comgás has natural gas supply contracts with specific characteristics, such as minimum withdrawal obligations by the Comgás (take or pay for commodity and ship or pay for transportation), that is, if Comgás consumes below contractual obligations, it must make payment of the differences between the volume consumed and the minimum contracted volumes, and may compensate them (through consumption) over the period of validity of the respective contract, provided that consumption exceeds the contracted minimum quantity. In addition, the supplier allows in contractual clause that there is recovery of the volume eventually accumulated for the term of 365 days after the termination of the contracts.

Therefore, it is currently forecast to recover all the cumulative volume since, during the recovery period provided for in the agreement, there will be no new accumulation related to the minimum commitments contracted for this period. Given the recoverable nature of this inventory, the amounts paid and not used were recognized in assets under “Paid and unused transportation.”

• Note 32 – Fair value of derivatives and other financial instruments

When the fair value of financial assets and liabilities cannot be derived from active markets, their fair value is determined using valuation techniques including the discounted cash flow model. The inputs to these models are taken from observable markets where possible, but when this is not feasible, a degree of judgment is required in determining fair values. Judgment is required in the determination of inputs such as liquidity risk, credit risk and volatility. Changes in these variables could affect the reported fair value of financial instruments.

• Note 33 – Post-employment benefits

The cost of defined benefit pension plans and other post-employment and the present value of the pension obligation is determined using actuarial valuations. An actuarial valuation involves the use of various assumptions which may differ from actual results in the future. These include the determination of the discount rate, future salary increases, mortality rates and future pension increases. A defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed by management at each reporting date.

• Note 34 – Share-based payments

The Company measures employees’ share-based compensation cost by referencing the fair value of the shares at the grant date. The estimation of fair value for share-based payment transactions requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the plan. This estimate also requires determining the most appropriate inputs to the valuation model including the assumption of the expected life of the stock option or stock grant, volatility and dividend yield. The assumptions and models used for estimating fair value for share-based payment transactions are disclosed in Note 34.

• Note 24 – Provisions for legal proceedings

Provisions for legal proceedings are recognized as other expenses when the Company has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated.

The assessment of probability loss includes the available evidence, hierarchy of laws, jurisprudence, the most recent court decisions and relevance in the legal system, as well as the opinion of outside counsel. Provisions are reviewed and adjusted according to circumstances, such as limitation period, conclusions of tax inspections or additional exposures identified based on new matters or court decisions.

Provisions for legal proceedings resulting from business combinations are estimated at fair value.

• Note 14—Investment in joint ventures

The Company has a 50% interest in a joint agreement. The joint venture agreements require unanimous consent from all parties for all relevant activities.

The two partners have direct rights to the assets of the partnership and are jointly and severally liable for the liabilities incurred by the partnership. This entity is therefore classified as a joint ventures and the Company recognizes its interest in the joint ventures using the equity method as described in Note 14.

Measurement of fair value

A number of the Company’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities.

The Company regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the valuation team assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of the accounting practices adopted in Brazil and the international standards IFRS, including the level in the fair value hierarchy in which such valuations should be classified.

When measuring the fair value of an asset or a liability, the Company uses observable market data when available. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:

• Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

• Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Company recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

2.4 Basis of measurement

The consolidated financial statements have been prepared on the historical cost basis except for the following material items in the consolidated statement of financial position:

• financial instruments at fair value through profit or loss;

• derivative financial instruments at fair value through profit or loss;

• loans measured at fair value through profit or loss;

• available-for-sale financial assets are measured at fair value;

• contingent consideration assumed in a business combination;

• employee’s defined benefit obligations are presented at the present value of the actuarial obligation net of the fair value of plan assets (Note 33).

(i) As of June 30, 2017, the Company increased its interest, in Comgás to 63.11% due to the capital increase arising from the partial use of the goodwill tax benefit, according to Ordinary / Extraordinary General Meeting of April 20, 2017, of the subsidiary Comgás. As a consequence, a loss in shareholders’ equity was recognized in the total amount of R$ 6,690.

According to the event stated in the note 1 Cosan S.A. increased its interest in Comgás from 63.11% to 79.87%

According to the event stated in the note 1 Company decreased its interest in Cosan S.A. from 62.29% to 58.21%

(ii) The Company recorded in the year ended December 31, 2017, a put option for the repurchase of shares of non-controlling shareholders, according to the shareholder agreement.

(iii) The direct subsidiary Cosan S.A. has a financial investment of 26,732,274 shares of Rumo S.A., which is an indirect subsidiary of the Company. Therefore, for the consolidated financial statements of the Company, the interest of 1.71% (0.86% stake as of December 31, 2016) in the share capital of Rumo S.A. is recognized as an equity investment.

(iv) Management has concluded that there are no material uncertainties that cast doubt on the continuity of the subsidiaries. Although they had a combined amount of uncovered liabilities of R$ 92,823 as of December 31, 2017, no events or conditions were identified that individually or collectively could raise significant doubts related to their ability to maintain their operational continuity. The subsidiaries have the financial support of the Company.

(v) Interest acquired in the companies during the year 2017.

(vi) On December 22, 2017, Rumo S.A. sold the interest on ALL Rail Management Ltda. to Qualytpar Participações S.A.

(a) Business combinations

Business combinations are accounted for using the acquisition method. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired and liabilities assumed. Any goodwill that arises is tested annually for impairment. Transaction costs are expensed as incurred, except if related to the issue of debt or equity.

The consideration transferred does not include amounts related to the settlement of pre-existing relationships. Such amounts are generally recognized in profit or loss.

(b) Non-controlling interests

For each business combination, the Company elects to measure any non-controlling interests in the acquisition either:

• at fair value; or

• at their proportionate share of the acquirer’s identifiable net assets, which are generally at fair value.

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions – that is, as transactions with the owners in their capacity as owners.

(c) Subsidiaries

Subsidiaries are all entities over which the Company has control. Subsidiaries are fully consolidated from the date of acquisition of control, and continue to be consolidated until the date that control ceases to exist. They are deconsolidated from the date that control ceases.

The financial statements of subsidiaries are prepared for the same reporting period as that of the parent company, using consistent accounting policies.

(d) Investments in associates (equity method investees)

Associates are those entities in which the Company has significant influence, but not control or joint control, over the financial and operating policies.

Investments in associates are accounted for under the equity method and are recognized initially at cost. The cost of the investment includes transaction costs.

Under the equity method of accounting, the share attributable to the Company of the profit or loss for the period of such investments is accounted for in the statement of profit or loss, in “Equity in investees.” Unrealized gains and losses arising on transactions between the Company and the investees are eliminated based on the percentage of interest held in such investees. The other comprehensive income of subsidiaries, associates and jointly controlled entities is recorded directly in the Company’s shareholders’ equity, in “Other comprehensive income.”

(e) Investments in joint ventures (equity method investees)

The Company has interests in joint ventures, in which contractual arrangement establishes joint control over the voting and economic activities of the entity. The contractual arrangements require unanimous agreement for financial and operating decisions among the ventures. The Company recognizes its interest in the joint ventures using the equity method (Note 14).

(f) Transactions eliminated on consolidation

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements.

Unrealized gains arising from transactions with equity accounted investees are eliminated against the investment to the extent of the Company’s interest in the investee. Unrealized losses are similarly eliminated, but only to the extent that there is no evidence of impairment.

3.2 Foreign currency

a) Foreign currency transactions

Transactions in foreign currencies are translated to the respective functional currencies of each subsidiary using the exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are translated to the functional currency using the exchange rate at the reporting date.

b) Foreign operations

The assets and liabilities derived from foreign operations, including goodwill and fair value adjustments arising on acquisition, are translated to Brazilian Reais using the exchange rates at the reporting date. Income and expenses of foreign operations are translated to Brazilian Reais using the exchange rates at the dates of the transactions.

Foreign currency differences are recognized in other comprehensive income, and presented in the foreign currency translation reserve (translation reserve) in equity. However, if the foreign operation is a non-wholly owned subsidiary, then the relevant proportion of the translation difference is allocated to non-controlling interests. When a foreign operation is disposed of such that control, significant influence or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal.

c) Translation of subsidiaries and associates’ financial statements

These consolidated financial statements have been translated to the Brazilian Real using the following criteria:

(a) assets and liabilities have been translated using the exchange rate at the balance sheet date;

(b) statement of profit or loss, comprehensive income and statement of cash flows have been translated using the monthly average exchange rate; and

(c) shareholders’ equity has been translated using the historical exchange rate.

Translation effects have been recognized in shareholders’ equity in “Cumulative translation adjustment.”

The consolidated financial statements of each subsidiary included in these consolidated financial statements and equity method investments are prepared based on their respective functional currencies. For subsidiaries whose functional currency is a currency other than the Brazilian Real, asset and liability accounts are translated into the Company’s reporting currency using exchange rates in effect at the date of the statement of financial position, and income and expense items are translated using monthly average exchange rates and shareholders’ equity has been translated using the historical exchange rate. The resulting translation adjustments are reported in a separate component of shareholders’ equity, as cumulative translation adjustment.

The exchange rate of the Brazilian Real (R$) to the U.S. Dollar (U.S.$) was R$ 3.3080 at December 31, 2017, R$ 3.2591 at December 31, 2016 and R$ 3.9048 at December 31, 2015.

3.3 Financial instruments

(i) Non-derivative financial assets

The Company initially recognizes loans and receivables on the date that they are originated. All other financial assets (including assets designated as at fair value through profit or loss) are recognized initially on the trade date, which is the date that the Company becomes a party to the contractual provisions of the instrument.

The Company classifies non-derivative financial assets into the following categories: financial assets at fair value through profit or loss, held-to-maturity financial assets, loans and receivables.

a) Financial assets at fair value through profit or loss

A financial asset is classified at fair value through profit or loss if it is classified as held-for-trading or is designated as such on initial recognition. Financial assets are designated at fair value through profit or loss if the Company manages such investments and makes purchase and sale decisions based on their fair value in accordance with the Company’s documented risk management or investment strategy. Attributable transaction costs are recognized in profit or loss as incurred. Financial assets at fair value through profit or loss are measured at fair value and changes therein, which takes into account any dividend income, are recognized in profit or loss.

i. Marketable securities

Investments in securities with a maturity date greater than three months at the date of purchase and other securities for which there is more than an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal

b) Loans and receivables

Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Such assets are recognized initially at fair value plus any directly attributable transaction costs. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method, less any impairment losses.

Loans and receivables comprise cash and cash equivalents, restricted cash , trade and other receivables.

Cash and cash equivalents

Cash and cash equivalents comprise cash balances, call deposits and highly liquid short-term investments with maturities of three months or less from the acquisition date that are subject to an insignificant risk of changes in their fair value, and are used by the Company in the management of its short-term commitments.

c) Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial assets that are designated as available-for-sale or are not classified in any of the above categories of financial assets. Available-for-sale financial assets are recognized initially at fair value plus any directly attributable transaction costs.

Subsequent to initial recognition, the financial assets are measured at fair value and changes therein, other than impairment losses and foreign currency gain/losses on available-for-sale debt instruments, are recognized in other comprehensive income and presented in the consolidated statements of changes in equity. When an investment is derecognized, the gain or loss accumulated in equity is reclassified to profit or loss.

Derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when:

• The rights to receive cash flows from the asset have expired; or

• 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 (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and, to what extent, it has retained the risks and rewards of ownership.

When it has neither transferred nor retained substantially all of the risks and rewards of the asset nor transferred control of it, the asset is recognized to the extent of the Company’s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

(ii) Non-derivative financial liabilities

The Company initially recognizes debt securities issued and subordinated liabilities on the date that they are originated. All other financial liabilities are recognized initially on the trade date, which is the date that the Company becomes a party to the contractual provisions of the instrument.

The Company derecognizes a financial liability when its contractual obligations are discharged, cancelled or expire.

The Company classifies non-derivative financial liabilities, except contingent consideration, as other financial liabilities. Such financial liabilities are initially recognized at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these financial liabilities are measured at amortized cost using the effective interest method.

Financial liabilities comprise loans and borrowings, debt securities issued, bank overdrafts, and trade and other payables.

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires.

When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the statement of profit or loss.

(iii) Share capital

Ordinary shares

Incremental costs directly attributable to the issue of ordinary shares are recognized as a deduction from equity. Income taxes relating to transaction costs of an equity transaction are accounted for in accordance with IAS 12.

Preference shares

Non-redeemable preference shares are classified as equity, because they bear discretionary dividends, do not contain any obligations to deliver cash or other financial assets and do not require settlement in a variable number of the Company’s equity instruments. Discretionary dividends thereon are recognized as equity distributions on approval by the Company’s shareholders.

Mandatory minimum dividends as defined in the bylaws are recognized as liabilities.

(iv) Derivative financial instruments, including hedge accounting

The Company holds derivative financial instruments to hedge its foreign currency and interest rate risk exposures. Embedded derivatives are separated from the host contract and accounted for separately if:

(a) The economic characteristics and risks of the host contract and the embedded derivative are not closely related;

(b) A separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

(c) The combined instrument is not measured at fair value through profit or loss.

On initial designation of the derivative as a hedging instrument, the Company formally documents the relationship between the hedging instrument and hedged item, including the risk management objectives and strategy in undertaking the hedge transaction and the hedged risk, together with the methods that will be used to assess the effectiveness of the hedging relationship. The Company makes an assessment, both at the inception of the hedge relationship as well as on an ongoing basis, of whether the hedging instruments are expected to be highly effective in offsetting the changes in the fair value or cash flows of the respective hedged items attributable to the hedged risk, and whether the actual results of each hedge are within a range of 80% – 125%. For a cash flow hedge of a forecast transaction, the transaction should be highly probable to occur and should present an exposure to variations in cash flows that ultimately could affect reported profit or loss.

Derivatives are initially recognized at fair value; any attributable transaction costs are recognized in profit or loss as incurred. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are accounted for as described below:

• Cash flow hedges

When a derivative is designated as the hedging instrument in a hedge of the variability in cash flows attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction that could affect profit or loss, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income and presented in the hedging reserve in equity. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss.

When the hedged item is a non-financial asset, the amount accumulated in equity is retained in other comprehensive income and reclassified to profit or loss in the same period or periods during which the non-financial item affects profit or loss. If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated or exercised, or the designation is revoked, then hedge accounting is discontinued prospectively. If the forecast transaction is no longer expected to occur, then the balance in equity is reclassified to profit or loss.

• Fair value hedge

Changes in fair value of derivatives, that are designated and qualify as fair value hedge, are recorded in the statement of profit or loss, with any changes in fair value of the hedged asset or liability that are attributable to the hedged risk. The Company applies hedge accounting for fair value hedges to protect itself against the risk of changes in interest rates and foreign exchange rates on loans. The gain or loss related to the effective portion of interest rate swaps to protect against fixed rate borrowings is recognized in the statement of profit and loss as “Financial expenses.” The gain or loss related to the ineffective portion is recognized in the statement of profit or loss as “Other gains (losses), net.” Changes in fair value of fixed rate borrowings hedged attributable to interest rate risk are recognized in the statement of profit or loss as “Financial expenses.”

If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the method of effective interest rate is used, is amortized to income over the period to maturity.

• Embedded derivatives

Changes in the fair value of separated embedded derivatives are recognized immediately in profit or loss.

• Other derivative financial instruments

When a derivative financial instrument is not designated in a hedge relationship and does not qualify for hedge accounting, all changes in its fair value are recognized immediately in profit or loss.

3.4 Inventory

Inventory is recorded at the lower of average cost of acquisition or production and net realizable value, whichever the less.

Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

Provisions for slow-moving or obsolete inventory are recorded when deemed necessary by management. The cost of finished goods and work in progress comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). It excludes borrowing costs.

3.5 Property, plant and equipment

(a) Recognition and measurement

Items of property, plant and equipment are measured at cost less accumulated depreciation and any accumulated impairment losses.

Cost includes expenditures that are directly attributable to the acquisition of the asset. The cost of constructed assets includes:

• the cost of materials and direct labor;

• any other costs directly attributable to bringing the assets to a working condition for their intended use;

• an estimate of the costs of dismantling and removing the items and restoring the site on which they are located, when the Company has an obligation to remove the asset or restore the site; and

• capitalized borrowing costs.

Cost also includes transfers from equity of any gain or loss on qualifying cash flow hedges of foreign currency purchases of property, plant and equipment. Purchased software that is integral to the functionality of the related equipment is capitalized as part of that equipment.

When components of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

Any gain or loss on disposal of an item of property, plant and equipment, calculated as the difference between the net proceeds from disposal and the carrying amount of the item, is recognized in profit or loss.

(i) Reclassification to investment property

When the use of a property changes from held to use to investment property, the property is remeasured at fair value and reclassified as investment property. Any gain or loss arising on this remeasurement is recognized in equity.

(ii) Subsequent costs

Subsequent expenditure is capitalized only when it is probable that the future economic benefits associated with the expenditure will flow to the Company. Ongoing repairs and maintenance are expensed as incurred.

(iii) Depreciation

Items of property, plant and equipment are depreciated from the date they are available for use or, in respect of constructed assets, from the date that the asset is completed and ready for use.

Depreciation is calculated on the carrying value of property, plant and equipment less their estimated residual values using the straight-line basis over their estimated useful lives. Depreciation is generally recognized in profit or loss, unless it is capitalized as part of the cost of another asset. Assets recognized under finance leases are depreciated over the shorter of the lease term and their useful lives unless it is reasonably certain that the Company will obtain ownership by the end of the lease term. Land is not depreciated.

Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets as follows:

Buildings and improvements	4% to 5%
Machinery, equipment and facilities	8% to 11%
Airplanes, vessels and vehicles	10% to 20%
Railcars	2.9% to 6%
Locomotives	3.33% to 8%
Permanent railways	4%
Furniture and fixtures	10% to 15%
Computer equipment	20%

Costs of normal periodic maintenance are recorded as expenses when incurred when the components will not improve the production capacity or introduce improvements to the equipment.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed annually and adjusted prospectively. During the fiscal year ended December 31, 2017, the subsidiary Rumo S.A. conducted a useful life review of a group of approximately 200 locomotives allocated to the logistics segment. Locomotives comprise individual components with different useful lives, and the review resulted in a reduction of useful lives of some components to reflect the time that the subsidiary Rumo intends to use those components through its economic life. The new useful life was applied starting from January 1^st 2017.

Depreciation methods such as useful lives and residual values are reviewed at each year-end, or when there is significant change without an expected consumption pattern, such as relevant incident and technical obsolescence. Any adjustments are recognized as changes in accounting estimates, if appropriate.

3.6 Intangible assets and goodwill

(a) Goodwill

Goodwill is measured at cost less accumulated impairment losses. With respect to equity method investees, the carrying amount of goodwill is included in the carrying amount of the investment, and any impairment loss is allocated to the carrying amount of the equity method investee as a whole.

(b) Other intangible assets

Other intangible assets that are acquired by the Company and have a finite life are measured at cost less accumulated amortization and any accumulated impairment losses.

(c) Subsequent expenditure

Subsequent expenditures are capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditures are recognized in profit or loss as incurred.

(d) Amortization

Except for goodwill, intangible assets are amortized on a straight-line basis over their estimated useful lives, from the date that they are available for use or acquired.

Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(e) Contracts with customers

Costs incurred on development of gas systems for new clients (including pipelines, valves, and general equipment) are recognized as intangible assets and amortized over the contract period.

(f) Intangible assets related to the concession rights agreement

The Company has a public concession agreement for a gas distribution service in which the Concession Authority controls what services will be provided and the price, as well it holds a significant participation in the infrastructure at the end of the concession. This concession agreement represents the right to charge users for gas supply during the term of the agreement. Accordingly, the Company recognizes this right as an intangible asset

The intangible asset comprises: (i) the concession right recognized upon the business combination of Comgás, which is being amortized over the concession period on a straight line basis, considering the extension of the distribution services for another 20 years; and (ii) the acquired or constructed assets underlying the concession necessary for the distribution of gas, which is being depreciated to match the period over which the future economic benefits of the asset are expected to accrue to the Company, or the final term of the concession, whatever occurs first. This period reflects the economic useful lives of each of the underlying assets that comprise the concession. This economic useful life is also used by the regulator, The Natural Gas Agency of the State of São Paulo, to determine the basis for measuring the tariff for rendering the services under the concession.

The concession agreement was signed on May 31, 1999 with an initial term of 30 years. Subject to approval of the Conceding Authority, the Company may request only once the extension of the distribution services for another 20 years. When the concession is terminated, the assets linked to the rendering of gas distribution services will be returned to the Conceding Authority, and the Company will be entitled to receive an indemnity to be determined based on assessments and evaluations considering the book values to be calculated at the time.

The concession contract determines that the tariff charged by Comgás be reviewed annually, in May, with the aim to realign the tariff charged to consumers to the cost of the gas and adjust for inflation.

Once the concession is terminated, the Company has the right to request the reversion to the Granting Authority of the assets and facilities linked to the gas distribution service. Currently, the amounts related to indemnification are not pre-established or determinable, that’s why the Company did not apply the bifurcated model for the accounting of the financial asset.

Concession rights generated in the business combination of ALL was fully allocated to the Rumo Malha Norte concession and amortized on a straight-line basis.

3.7 Impairment

(i) Non-derivative financial assets

A financial asset not classified as at fair value through profit or loss, including an interest in an equity-accounted investee, is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset, and that loss event(s) had an impact on the estimated future cash flows of that asset that can be estimated reliably.

(a) Financial assets measured at amortized cost

An impairment loss in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset’s original effective interest rate. Losses are recognized in profit or loss and reflected in an allowance account against loans and receivables or held-to-maturity investment securities. If, in a subsequent period, the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the statement of profit or loss.

(b) Available-for-sale financial assets

Impairment losses on available-for-sale financial assets are recognized by reclassifying the accumulated losses recorded in equity to profit or loss. The cumulative loss that is reclassified from equity to profit or loss is the difference between the acquisition cost, net of any principal repayment and amortization, and the current fair value, less any impairment loss recognized previously in profit or loss.

(ii) Non-financial assets

The carrying amounts of the Company’s non-financial assets, except investment property, inventories and deferred tax assets, are reviewed at each reporting date to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill is tested annually for impairment. An impairment loss is recognized if the carrying amount of an asset or cash-generating unit (“CGU”) exceeds its recoverable amount.

The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU. For impairment testing, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or CGUs. Subject to an operating segment ceiling test, CGUs to which goodwill has been allocated are aggregated so that the level at which impairment testing is performed reflects the lowest level at which goodwill is monitored for internal reporting purposes. Goodwill acquired in a business combination is allocated to Companies of CGUs that are expected to benefit from the synergies of the combination.

Impairment losses are recognized in profit or loss. Impairment losses recognized for CGUs are allocated first to reduce the carrying amount of any goodwill allocated to the CGU (group of CGUs), and then to reduce the carrying amounts of the other assets in the CGU (group of CGUs) on a pro rata basis.

An impairment loss with respect to goodwill is not reversed. For other assets, an impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

3.8 Provisions

A provision is recognized if, as a result of a past event, the Company has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

3.9 Employee benefits

• Short-term employee benefits

Short-term employee benefit obligations are measured on an undiscounted basis and are expensed when the related service is provided. A liability is recognized for the amount expected to be paid under short-term cash bonus or profit-sharing plans if the Company has a present legal or constructive obligation to pay these amounts as a result of past services provided by the employee, and the obligation can be estimated reliably.

• Share-based payment transactions

The grant-date fair value of share-based payment awards granted to employees is recognized as an employee compensation expense, with a corresponding increase in equity, over the period that the employees become unconditionally entitled to the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market performance conditions are expected to be met, such that the amount ultimately recognized as an expense is based on the number of awards that meet the related service and non-market performance conditions at the vesting date. For share-based payment awards with non-vesting conditions, the grant-date fair value of the share-based payment is measured to reflect such conditions and there is no true-up for differences between expected and actual outcomes.

The fair value of the amount payable to employees with respect to share appreciation rights, which are settled in cash, is recognized as an expense with a corresponding increase in liabilities, over the period that the employees become unconditionally entitled to the cash payment. The liability is remeasured at each reporting date and at settlement date based on the fair value of the share appreciation rights. Any changes in the liability are recognized as employee benefit expenses in profit or loss.

The accounting for modification on plans depends on whether the modification changes the classification of the arrangement and whether the changes are beneficial to the counterparty.

If a modification increases the number of equity instruments granted, then the entity recognizes the fair value of the additional equity instruments measured at the date of modification. The additional share-based payment cost is attributed over the period from the date of modification to the end of the vesting period of the additional equity instruments.

Cancellations or settlements of equity-settled share-based payments during the vesting period by the entity or by the counterparty are accounted for as accelerated vesting; therefore, the amount that would otherwise have been recognized for services received is recognized immediately.

• Defined contribution plans

A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions into a separate entity and has no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution plans are recognized as an employee benefit expense in profit or loss in the periods during which related services are rendered by employees. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in future payments is available. Contributions to a defined contribution plan that is due more than 12 months after the end of the period in which the employees render the service are discounted to their present value.

• Defined benefit plans

The Company is the sponsor of defined benefit pension plans for some of its employees. A defined benefit plan is a post-employment benefit plans other than a defined contribution plan.

The liability recognized in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method.

The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows, using interest rates that are denominated in the currency in which the benefits will be paid, and that have terms approximating to the terms of the related obligation.

Gains and losses arising from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur, directly in other comprehensive income.

Changes in the present value of the defined benefit obligation resulting from plan amendments or curtailments are recognized immediately in profit or loss as past service costs.

Some of the Company’s pension plan, even though it is substantially defined contribution, has a variable component, whose risk is linked to the payment of minimum benefit and to the increase of the future contributions of the sponsors in the benefits in the event of Death Tax of the active taxpayer as well as in Disability Retirement, limited to three salaries. Any actuarial liability calculated, is recorded by the Company.

• Other long-term employee benefit

The Company’s net obligation in respect of long-term employee benefits other than pension plans is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value, and the fair value of any related assets is deducted. The discount rate is the yield at the reporting date of the financial statements for the high credit quality bonds, and maturity dates approximating the terms of the Company’s obligations and that are denominated in the currency in which the benefits are expected to be paid. The calculation is performed using the projected unit credit method. Any actuarial gains and losses are recognized in profit or loss in the period in which they arise.

3.10 Revenue

(a) Sales of goods

Revenue from the sale of goods, in the ordinary course of business, is measured at the fair value of the consideration received or receivable, net of returns, trade discounts and volume rebates. Revenue is recognized when significant risks and rewards of ownership have been transferred to the customer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably. If it is probable that discounts will be granted and the amount can be measured reliably, then the discount is recognized as a reduction of revenue as the sales are recognized.

(b) Services rendered

Revenues from services are recognized when the amount of revenue can be measured reliably, when it is probable that the economic benefits associated with the transaction will flow to the Company, when the stage of completion of the transaction at the end of the reporting period can be measured reliably, as well as when its amount and related costs can be measured reliably. Service prices are established based on service orders or contracts. Services for which payment is made in advance are recorded as deferred revenue in other liabilities and recognized in revenue when the services are rendered.

The Company revenue recognizes revenue as follows:

• Billed revenue

Revenue from gas distribution services is recognized when its amount can be reliably measured, and is recognized in profit or loss when the volumes are delivered to customers.

• Unbilled revenue

Unbilled gas refers to the portion of gas supplied for which metering and billing to customers have not yet occurred. This amount is estimated based on the period between measurement and the last day of the month.

The actual volume billed may be different from estimates. The Company believes that, based on its historical experience with similar operation, the unbilled estimated amount will not significantly differ from actual amounts.

• Concession construction revenue

The construction of the infrastructure necessary for gas distribution is considered a construction service rendered to the Conceding Authority, and the related income is recognized in profit or loss at finishing stage of the work.

Construction costs are recognized by reference to the stage of completion of the construction activity at the end of the reporting period, and are included in cost of sales.

(c) Deferred revenue

The Company´s deferred revenue consists in advances received from clients seeking investment in fixed assets in return for a rail service contract requiring future performance of services by the Company.

3.11 Government grants

Government grants are recognized where there is reasonable assurance that the grant will be received and all attached conditions will be complied with. The indirect subsidiary Rumo Malha Norte has a fiscal incentive whose benefit includes a reduction of 75% on income tax based on operation profit beginning in 2008 until 2024.

3.12 Leases

The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at the inception date.

a) Leased assets

Leases of property, plant and equipment that transfer to the Company substantially all of the risks and rewards of ownership are classified as finance leases. The leased assets are measured initially at an amount equal to the lower of their fair value and the present value of the minimum lease payments. Subsequent to initial recognition, the assets are accounted for in accordance with the accounting policy applicable to that asset.

A leased asset is depreciated over the useful life of the asset. However, if there is no reasonable certainty that the Company will obtain ownership by the end of the lease term, the asset is depreciated over the shorter of the estimated useful life of the asset and the lease term.

Assets held under other leases are classified as operating leases and are not recognized in the Company’s statement of financial position.

b) Lease payments

Payments made under operating leases are recognized in profit or loss on a straight-line basis over the term of the lease. Lease incentives received are recognized as an integral part of the total lease expense, over the term of the lease.

Minimum lease payments made under finance leases are apportioned between the finance expense and the reduction of the outstanding liability. The finance expense is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability.

The amounts paid in advance by the Company are recorded as assets and allocated in income linearly during the term of the contract. The expenses incurred during the grace period are recorded in income and maintained as payables, being written off in proportion to the payment of current installments.

3.13 Finance income and finance expense

Finance income comprises interest income on funds invested (including available-for-sale financial assets), dividend income, gains on the disposal of available-for-sale financial assets, fair value gains on financial assets at fair value through profit or loss, gains on the remeasurement to fair value of any pre-existing interest in an acquire in a business combination, gains on hedging instruments that are recognized in profit or loss and reclassifications of net gains previously recognized in other comprehensive income. Interest income is recognized as it accrues in profit or loss, using the effective interest method. Dividend income is recognized in profit or loss on the date that the Company’s right to receive payment is established, which in the case of quoted securities is normally the ex-dividend date.

Finance expense comprise interest expense on borrowings, unwinding of the discount on provisions and deferred consideration, losses on disposal of available-for-sale financial assets, dividends on preference shares classified as liabilities, fair value losses on financial assets at fair value through profit or loss and contingent consideration, impairment losses recognized on financial assets (other than trade receivables), losses on hedging instruments that are recognized in profit or loss and reclassifications of net losses previously recognized in other comprehensive income.

Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are recognized in profit or loss using the effective interest method.

Foreign currency gains and losses on financial assets and financial liabilities are reported on a net basis as either finance income or finance cost depending on whether the net foreign currency fluctuations result in a gain or loss position.

3.14 Taxes

Income taxes are comprised of income tax and social contribution at a combined rate of 34%. Tax expense comprises current and deferred tax. Current tax and deferred tax is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income.

Certain subsidiaries measure income tax and social contribution due under the Brazilian presumed profits regime. The presumed profit came up from a percentage of 32% of operating revenues. Under the aforementioned regime the applicable tax rate is for income tax is 15% over the presumed profit, plus an additional 10% when operating revenues exceed of R$ 240, and 9% over the presumed profit for social contribution.

a) Current tax

Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years.

b) Deferred tax

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes and tax loss. Deferred tax is not recognized for:

• temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss;

• temporary differences related to investments in subsidiaries, associates and joint ventures to the extent that the Company is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and

• taxable temporary differences arising on the initial recognition of goodwill.

The measurement of deferred tax reflects the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. For investment property that is measured at fair value, the presumption that the carrying amount of the investment property will be recovered through sale has not been rebutted.

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realized simultaneously.

A deferred tax asset is recognized for loss carryforwards, tax credits and deductible temporary differences to the extent that it is probable that future taxable income will be generated in the future. Deferred tax assets are reviewed at each reporting date and written off to the extent that it is no longer probable that the related tax benefit will be realized.

c) Sales taxes

Net revenue is recognized net of discounts and sales taxes.

d) Tax exposures

In determining the amount of current and deferred tax, the Company takes into account the impact of uncertain tax positions and whether additional taxes and interest may be due. This assessment relies on estimates and assumptions and may involve a series of judgments about future events. New information may become available that causes the Company to change its judgment regarding the adequacy of existing tax liabilities; such changes to tax liabilities will impact tax expense in the period that such a determination is made.

3.15 Cash flow

• Non-cash transaction

During the year ended December 31, 2017, the Company made the following transactions not involving cash and therefore not reflected in the consolidated statement of cash flows:

(i) Forward purchase of property, plant and equipment in the amount of R$105,102.

• Disclosure of interest and dividends

(i) The Company disclosures the dividends and interest on shareholders’ equity received as cash flow from investing activities, with the purpose of avoiding distortions in its cash flows from operation activities.

(ii) Interest received or paid is classified as cash flow from financing activities, as it is considered to refer to the costs of obtaining financial resources.

New standards and interpretations not yet effective

New standards and interpretations not yet effective

4 New standards and interpretations not yet effective

A number of new standards and amendments to standards are effective for annual periods beginning after January 1, 2018 and earlier application is permitted; however, the Group has not early adopted the following new or amended standards in preparing these consolidated financial statements.

a) Estimated impact of the adoption of IFRS 15 and IFRS 9

The Company estimated the impact of the adoption of IFRS 15—Revenue from Contract with Customers and IFRS 9—Financial Instruments on equity on January 1, 2018, based on valuations carried out up to the date of issuance these statements. The actual impacts of adopting the standards on January 1, 2018 may be different as the Company did not finalize the testing and evaluation of controls on these new standards and the new accounting policies are subject to change until the Company presents its first statements including the date of initial application.

The main components of the estimated adjustment are as follows:

i) recognition of incremental costs to obtain contract and customer payment to be paid; and

ii) impairment losses on financial assets.

b) IFRS 15—Customer Contract Revenue

IFRS 15 includes as a fundamental principle the recognition of revenue when goods or services are transferred to customers at the transaction price. Revenue is recognized according to this principle by applying a 5 step model:

• Step 1: Identify the contracts with the client;

• Step 2: Identify the performance obligations defined in the contract;

• Step 3: Determine the price of the transaction;

• Step 4: Allocate the price of the transaction to the performance obligations provided for in the agreement; and

• Step 5: Recognize revenue when (or as) the entity meets each performance obligation.

IFRS 15 introduces a comprehensive framework to determine whether and when revenue is recognized, and how much revenue is received. IFRS 15 replaces current revenue recognition standards.

The Company recognizes revenues from the following main sources:

(i) Sale of products

The Company recognizes sales revenues upon delivery to the customer. Delivery is considered to be the moment when the customer accepts the goods, and the risks and benefits related to the property are transferred. Revenue is recognized at this time as long as revenue and costs can be measured reliably, receipt of the consideration is probable and there is no continuous involvement of management with the products.

In accordance with IFRS 15, revenue must be recognized when the customer obtains control of the products. For contracts with customers where the sale is generally expected to be the only execution obligation, the adoption of IFRS 15 should have no impact on revenue and results. The Company expects revenue recognition to occur at a time when control of the good is transferred to the customer, usually at the time of delivery of the goods.

The Company operates in the production and distribution of lubricants including the brands Mobil and Comma, as well as the production and distribution of biomass pellets. Products are sold in contracts identified with individual customers and in sets, as a package of goods or services.

Some lubricant sales contracts cannot be purchased separately from a package of services. However, the goods and services are clearly distinct in the contracts. This sales modality represents two separate performance obligations and therefore revenue will be recognized for each of these performance obligations when control of the respective goods and services is transferred to the customer. Although IFRS 15 requires that the transaction price be allocated to different performance obligations based on the independent selling price, Management does not expect the allocation of revenues from the sale of lubricants and services rendered to be significantly different from that currently practiced, in which revenues are identified, measured and recorded separately.

(ii) Services provided

The Company provides gas distribution services through the subsidiary Comgás and logistics services through the subsidiary Cosan Logística. Based on the Company’s assessment, the fair value and selling prices of individual services are broadly similar. Therefore, the Company does not expect the application of IFRS 15 to result in significant differences in the recognition of revenue for these services.

(iii) Other effects

a) Incremental cost to obtain contracts

The Company has identified certain lubricant sales agreements that contain commission clauses. These clauses are under evaluation that are included as incremental costs associated with contract acquisition and are expressly chargeable to the customer. In the Company’s evaluation, when IFRS 15 is adopted, certain contracts may be recognized as assets due to the incremental cost of obtaining a customer agreement. These will be amortized on a systematic basis consistent with the transfer of the goods or services to the customers. On December 31, 2017, the amount of R$ 39,275 related to sales commissions was recognized as selling expenses.

The Company was presenting expenses related to contracts as sales expenses

b) Disposal of non-financial assets

The recognition and measurement requirements in IFRS 15 also apply to the recognition and measurement of any gains or losses on the disposal of non-financial assets (such as property, plant and equipment and intangible assets), when such disposal does not occur in the normal course of business. However, there is no expectation that the effect of these changes will be material to the Company.

(iv) Presentation and disclosure requirements

The presentation and disclosure requirements in IFRS 15 are more detailed than those contained in the current IFRS. The presentation requirements represent a significant change from the current practice and significantly increase the volume of disclosures required of the Company’s financial statements. Many of the disclosure requirements of IFRS 15 are new and the Company has assessed that the impact of some of them will be significant. In particular, the Company expects the explanatory notes to the financial statements to require expansion due to the disclosure of significant judgments made. These include determining the timing of the transaction price of contracts that include variable consideration, as the transaction price has been attached to the performance obligation and the assumptions used to estimate the individual selling prices of each performance obligation. In addition, as required by IFRS 15, the Company will disaggregate the recognized revenues from contracts that include the sale of both goods and services. In 2017, the Company continued to test the internal controls, policies and procedures required to collect and disclose the information required.

(v) Transition

The Company plans to adopt IFRS 15 using the cumulative effect method, with initial application of the standard at the initial date (January 1, 2018). As a result, the Company will not apply the requirements of IFRS 15 to the comparative period presented.

The Company plans to use the practical expedients for concluded contracts. This means completed contracts that have commenced and ended in the same comparative presentation period, as well as contracts that concluded at the beginning of the earliest period presented, will not be restated.

c) IFRS 9—Financial Instruments

In July 2016, the IASB International Accounting Standards Board issued the final version of IFRS 9—Financial Instruments which replaces IAS 39—Financial Instruments: Recognition and Measurement and all previous versions of IAS 39. The new standard brings together the three aspects of the accounting of financial instruments: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for fiscal years beginning on or after January 1, 2018, without prior application permission. With the exception of hedge accounting, retrospective application is necessary, but providing comparative information is not mandatory. For hedge accounting, the requirements are generally applied prospectively, with some limited exceptions.

The Company plans to adopt the new standard on the effective date required and will not restate comparative information. In 2017, the Company conducted a detailed impact assessment of the three aspects of IFRS 9. This evaluation is based on information currently available and may be subject to changes arising from reasonable and bearable information being made available by the Company in 2018, when it adopts IFRS 9. In general, the Company does not foresee any significant impact on the financial statements or shareholders’ equity, except for the effect of applying the impairment requirements of IFRS 9. The Company expects an increase in loss provisions resulting in a negative impact on shareholders’ equity as discussed below. In addition, the Company will implement changes to the classification of certain financial instruments.

i) Classification and measurement of financial assets

The Company does not expect a significant impact on its balance sheet or equity in applying the classification and measurement requirements of IFRS 9. We expect to continue to measure at fair value all financial assets currently held at fair value. Equity instruments, currently held for sale, with gains and losses recorded in profit or loss, will continue to be measured at fair value through profit or loss.

Loans and receivables are held by the Company to obtain contractual cash flows and should generate cash flows representing only payments of principal and interest. The Company analyzed the contractual cash flow characteristics of these instruments and concluded that they meet the amortized cost criteria in accordance with IFRS 9. Therefore, the reclassification to these instruments will not impact the balance sheet or equity.

The Company has assessed the impacts of gains and losses on financial liabilities attributable to its own risk and has not identified deviations that will result in an accounting for comprehensive income.

ii) Impairment – Financial Assets and Contractual Assets

IFRS 9 requires the Company to record the expected credit losses on all of its debt securities and trade accounts receivable, whether in 12 months or throughout the asset’s life. However, the Company has adopted the more simplified approach and will measure the expected credit losses over a lifetime because the trade accounts receivable and contractual assets do not represent a significant financing component. The provision will be determined by applying the percentage of expected losses on the financial assets to the overdue amounts and overdue loans that may impact the amount of provisioning expense for losses.

The estimated losses were calculated based on the actual experience of credit loss in recent years, and from observing the current conditions and forecasting future economic conditions.

The Company holds investments in debt instruments classified as securities, which are part of investment fund quotas measured at fair value through profit or loss. Therefore, no credit risk analysis of these assets is required.

iii) Hedge accounting

The Company has determined that all existing hedge relationships currently designated as effective hedging relationships will continue to qualify for hedge accounting in accordance with IAS 39. The Company has elected not to retrospectively apply IFRS 9 in the transition to the hedges where the Company excluded the items of progress of the hedge designation in accordance with IAS 39. As IFRS 9 does not change the general principles of how an entity responds to effective hedges, the application of the requirements of hedge of IFRS 9 will not have a significant impact on the Company’s financial statements.

iv) Other adjustments

In addition to the adjustments described above, associated with the adoption of IFRS 9, other items in the financial statements, such as deferred taxes, assets held for sale and liabilities associated with them, investments in associates and joint ventures will be adjusted as necessary. Foreign exchange differences in the conversion of foreign operations will also be adjusted.

d) IFRS 16 Leases

IFRS 16 introduces a single model for the accounting of leases in the balance sheet for tenants. A lessee recognizes a right of use asset that represents his right to use the leased asset and a lease liability that represents his obligation to make lease payments. Optional exemptions are available for short-term leases and low value items. The lessor’s accounting remains similar to the current standard, that is, lessors continue to classify leases as financial or operating.

IFRS 16 replaces existing lease standards, including IAS 17 Leasing Operations and IFRIC 4, SIC 15 and SIC 27 Complementary Aspects of Leasing Operations.

The standard is effective for annual periods beginning on or after January 1, 2019. Early adoption is permitted only for financial statements in accordance with IFRSs and only for entities that apply IFRS 15 Revenue from Contracts with Customers or before the date of initial application of IFRS 16.

The Company began an initial assessment of the potential impact on its financial statements. So far, the most significant impact identified is that the subsidiary Rumo will recognize new assets and liabilities for its operating leases. In the jointly-owned subsidiary Raízen, it is expected to have significant impacts on land leases. In addition, the nature of the expenses related to these leases will be changed, since IFRS 16 replaces the line operating lease expense due to depreciation of the right of use and interest on the lease liabilities. The Company has not yet decided whether to use the optional exemptions.

As a lessee, the Company may apply the standard using a:

- Retrospective approach; or

- Modified retrospective approach with optional practical expedients.

The lessee will apply this choice consistently to all of its leases. The Company should apply IFRS 16 initially on January 1, 2019. The Company has not yet determined which transition approach to apply.

The Company has not yet quantified the impact of adopting IFRS 16 on its assets and liabilities. The quantitative effect of the adoption of IFRS 16 will depend specifically on the transition method chosen, the use of practical expedients and recognition exemptions, and any additional leases that the Company will enter into. The Company expects to disclose its transition approach and quantitative information prior to adoption.

e) IFRIC 22 — Foreign Currency Transactions and Advance Consideration

IFRIC states that the date of the transaction for the purpose of determining the exchange rate should be the date on which the entity initially recognizes the non-monetary asset or liability arising from the payment or early receipt.

This interpretation takes effect for annual periods beginning on or after January 1, 2018. The initial adoption is permitted retrospectively, or prospectively.

Management conducted the analysis of the impacts of the initial adoption of IFRIC 22 and considered them to be immaterial. Thus, whether the adoption will be carried out prospectively or retrospectively is still being determined.

There are no other IFRS standards or IFRIC interpretations that have not come into effect and that are expected to have a material impact on the Company.

Operating segments

5    Operating segments

The following segment information is used by Cosan’s senior management (the “Chief Operating Decision Maker”) to assess the performance of the operating segments and to make decisions with regards to the allocation of resources. This information is prepared on a basis consistent with the accounting policies used in the preparation of the financial statements. Cosan evaluates the performance of its operating segments based on the measure of Earnings Before Interest Tax, Depreciation and Amortization (“EBITDA”). A reconciliation of EBITDA to profit (loss) is presented below.

Reported segments

(i)    Raízen Energia: production and marketing of a variety of products derived from sugar cane, including raw sugar (VHP), anhydrous and hydrated ethanol, and activities related to energy cogeneration from sugarcane bagasse. In addition, this segment holds interests in companies engaged in research and development on new technology;

(ii)    Raízen Combustíveis: distribution and marketing of fuels, mainly through a franchised network of service stations under the brand Shell throughout Brazil;

(iii)    Comgás: distribution of piped natural gas to part of the State of São Paulo (approximately 180 municipalities, including the region called Greater São Paulo) to customers in the industrial, residential, commercial, automotive, thermo generation and cogeneration sectors;

(iv)    Cosan Logística: logistics services for transport, storage and port loading of commodities, mainly for sugar products, leasing or lending of locomotives, wagons and other railway equipment; and

(v)    Moove: production and distribution of lubricants under the Mobil brand in Brazil, Bolivia, Uruguay and Paraguay, as well as European and Asian market with a Comma trademark.

Reconciliation

(i)    Cosan Corporate: other investments, in addition to the corporate activities of the Company. The Cosan Corporate segment’s includes the subsidiaries responsible for raising funds for the group.

Although Raízen Energia and Raízen Combustíveis are equity accounted joint ventures and are no longer proportionally consolidated since adoption of IFRS 11, senior management continues to review segment information. A reconciliation of these segments is presented in the column “Deconsolidated effects IFRS 11.”

The following statement of financial position and profit or loss selected information by segment was prepared on the same basis as the accounting practices used in the preparation of consolidated information:

Sale of credit rights

The Company recorded credit rights in the amount of R$ 426,438 as other assets and the respective legal fees in the amount of R$ 51,173 as other liabilities. In 2017, the requirements of the accounting policy were achieved and for that reason the credit right in the net amount of taxes of R$ 306,151 was recognized in the line of “other income,” with impact on cash flow statements.

In addition, the Company has additional claims to those mentioned above, which, because they are considered probable, were not recorded as representing contingent assets.

On December 21, 2017, there was a sale of credit rights related to the assets recorded in the balance sheet and also the contingent assets in the amount of R$ 1,340,000 (“purchase price”), arising from certain lawsuits, aiming at condemning the Union as a result of the fixing of sugar and alcohol prices below their cost of production. In addition to the acquisition price, the Company will be entitled to additional payments related to these receivables, provided that the result is positive. The additional payment will be calculated by applying 95% on the difference between the net value received from the Union credit rights by the transferee minus the return of the assignees and recognized in the results only upon receipt.

As a result of the sale of receivables, we had the following impacts:

(a) Financial discount recognized as financial expense in the amount of R$ 251,648 arising from the difference between the assignment of these rights for the amount of R$ 460,974 and the amount of assets previously recognized of R$ 712,622;

(b) Gain on the sale of credit rights net of tax and obligations in the amount of R$ 733,815 recorded as other revenues and. with impact on cash flow statements.

Investments in joint ventures

14 Investments in joint ventures

The Company entered into an agreement to form two joint ventures, accounting for 50% of the economic benefits of the companies. They are:

(i) Raízen Combustíveis which owns a network of, more than 6,027 fuel service stations throughout Brazil, 67 distribution terminals and 64 airports terminals for supplying aviation fuel; and

(ii) Raízen Energia, which produces and sells sugar, and ethanol and renders electric energy cogeneration services, the latter mainly from sugar cane bagasse. Raízen Energia is responsible for the production of, approximately, 2 billion liters of ethanol per year to supply the domestic and foreign market, 4.2 million tons of sugar and 940 MW of installed capacity of electricity. Raízen Energia cultivates harvests and processes sugar cane—the main raw material used in the production of sugar and ethanol.

Cosan has joint control over Raízen Combustíveis and Raízen Energia by virtue of its 50% share in the equity of both companies and the requirement for unanimous consent by all shareholders over decisions related to the significant activities. The investments have been classified as joint ventures under IFRS 11 and therefore the equity method of accounting is used for all periods presented in these consolidated financial statements.

Impairment testing of cash-generating units (“CGU”) goodwill

a) Cosan Logistics

The Company annually tests recoverable amounts of goodwill arising from business combination operations. Property, plant and equipment and defined-intangible assets that are subject to depreciation and amortization are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

For the purposes of impairment analysis, concession contracts were defined as cash-generating units. The base date for evaluation and annual testing is September 30.

During the year ended December 31, 2017, we did not identify impairment indicators, so that no impairment test was required for fixed assets and intangible assets with a defined useful life.

The balance of goodwill recorded by the Company is associated with the port lifting operation and terminals, so this cash-generating unit needs to be tested annually.

The recoverable amount of this cash-generating unit was determined by the net sales value of the unit, using the EBITDA multiples technique.

The main assumptions used were (i) EBITDA generated by the cash-generating unit in 2017, and (ii) the average of the multiples practiced by market agents for companies in the Company’s industry.

The calculation resulted in a recoverable amount of R$ 1,709,000, compared to a book value of R$ 811,618, which includes property, plant and equipment and intangible assets.

In the year ended December 31, 2017, no assets and goodwill had their consolidated value reduced by impairment. The determination of the recoverability of the assets depends on certain key assumptions as described above that are influenced by the market, technological, and economic conditions in place at the time this recovery is tested and, therefore, it is not possible to determine whether new losses by recovery will occur in the future and, if they occur, whether these would be material.

b) Cosan S.A.

The Company annually tests recoverable amounts of goodwill (intangible assets with indefinite useful lives) arising from business combinations operations. Property, plant and equipment and defined-intangible assets that are subject to depreciation and amortization are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable, which is not the case for the year.

The combined carrying amounts of goodwill allocated to each cash-generating unit are as follows:

	Consolidated
	December 31, 2017		December 31, 2016
Moove cash generating unit		751,391		614,765
Cosan cash-generating unit other business		43		43
Total goodwill		751,434		614,808

The recoverable amount is determined based on calculations of the value in use, using the discounted cash flow determined by Management based on budgets that take into account the assumptions related to each business, using information available in the market and previous performance. Discounted cash flows were drawn up over aten-year period and carried forward in perpetuity without considering a real growth rate. Management understands the use of periods greater than five years in the preparation of discounted cash flows as it reflects the estimated time of use of the asset and business groups.

The main assumptions used mainly consider the expectation of growth of the operations based on the Gross Domestic Product segmented, as well as taking into account the levels of average growth experienced in the last years and other macroeconomic aspects, as well as expectation of the price of sales of commodities, using discount rates that reflect specific business-related risks.

All of these future cash flows were discounted at a rate of 10.4% (weighted-average cost of capital) and a growth rate of the final value of 4% from 2027 reflecting specific risks related to the relevant assets in its cash generating unit.

An increase of 6.3 percentage points in the discount rate should change so that the estimated recoverable amount is equal to the book value. The dollar has an impact on projections and, therefore, a fluctuation of in exchange rate would have an effect on the estimate.

As of December 31, 2017 no expense for impairment of assets and goodwill was recognized. The determination of the recoverability of the assets depends on certain key assumptions as described above that are influenced by the market, technological and economic conditions in place at the time that such recovery is tested, and therefore, it is not possible to determine whether new reduction losses of recovery will occur in the future and, if they occur, whether these would be material.

Court Discussion

The Company is challenging in court the economic and financial unbalance of certain leases and concession contracts.

In April 2004, Rumo Malha Paulista filed an interlocutory injunction and subsequently Declaratory Action before the 21st Federal Court of Rio de Janeiro questioning the economic and financial unbalance of the Lease and Concession Agreements, due to the high disbursement incurred by the Company for the payment of labor judicial proceedings and other expenses involved, which are the responsibility of Rede Ferroviária Federal S.A., as provided in the bidding documents.

Rumo Malha Paulista required an injunction to suspend payment of installments due of the concession and lease agreements and to offset the credit balance resulting from labor amounts paid by Rumo with the amount charged by the Union. In April 2005, the injunction was granted, suspending the enforceability of installments for 90 days by determining the completion of expertise. In July 2005, the suspension was extended for another 90 days. In September 2005, the injunction was overturned by the Federal Court of Rio de Janeiro. In January 2006, the suspension of payment of installments was granted, by means of judicial deposit. The amount related to the lease payment was deposited in court until October 2007, when the Company obtained a court order to replace the judicial deposits with a bank guarantee. In October 2015, a decision was handed down that partially upheld the action recognizing the occurrence of economic and financial balance of the agreements, allowing the Company to perform the part of compensation of the amounts claimed in the match against presented debt. Nevertheless, the Company believes that all amounts discussed shall be offset against payables based on clauses 7 and 10 of the bidding documents.

Management, supported by the opinion of its legal counsel, assesses the chances of success as probable, but the financial liability remains recognized as it is a contractual obligation not yet discharged and still depend on offsetting with the Company’s reimbursement rights.

Rumo Malha Oeste also claiming the reestablishment of the economic-financial balance, lost by the cancellation of transportation contracts at the time of privatization, change in the regulatory environment and conditions set forth in the Privatization Tender—additionally, the growth forecasts that defined the value of the business did not materialize. The lawsuit is filed with the 16th Federal Court of Rio de Janeiro. To proceed with the legal discussion, the Company offered government securities (Treasury Bills—LFT) as an execution guarantee. In March 2008, the Company was authorized to replace the guarantee by a bank guarantee and in May 2008, the Company redeemed the treasury bills. In December 2014, a decision was handed down that upheld the action recognizing the occurrence of economic and financial balance of the contracts, with the amounts involved and certain related aspects still to be determined. In December 2015, the replacements of guarantee letters presented by Rumo were replaced with an insurance policy.

Management, supported by the opinion of its legal counsel, assesses the chances of success as probable, but the financial liability remains recognized as it is a contractual obligation not yet discharged and must still be offset against the company’s right to be reimbursed.

Judicial deposits at December 31, 2017 concerning the above claims totaled:

	December 31, 2017		December 31, 2016
Rumo Paulista		119,806		118,820
Rumo Oeste		20,690		19,464
		140,496		138,284

The judicial deposits are recorded in the “regulatory” group, as described in note 24.

The tariffs for the supply of gas to the different customer segments are authorized by the concession authority. In accordance with the terms of the Concession Agreement, the differences between the cost component of gas included in the tariffs charged to the customers and the actual cost of gas incurred are determined on a monthly basis and charged or credited to a regulation account (regulatory account).

Periodically, charges or credits in the tariffs are determined by the regulator with the objective of amortizing the amounts accumulated in this account.

The balance of this account is considered as an asset or as a liability, pursuant to the regulator’s set of accounts and for income tax purposes. However, this account is not recognized under IFRS, because the respective balance is not considered as an asset or as a liability, as its realization or liquidation depends on further purchases by the Company’s consumers.

(b) Commitments with supply contracts

Considering the current gas supply contracts, the subsidiary Comgás has a total financial commitment in an estimated present value of R$ 5.3 billion, which amount includes the minimum established in contract in both commodity and transportation.

(ii) The amounts that have been provisioned refer to tax assessments by the tax authorities related to several types of ICMS credits. Amongst them: (a) assessment notice related to ICMS payments for the purchase of raw materials which are considered for “use and consumption,” therefore, not eligible for compensation; (b) assessment, as sole obligor, for withholding of ICMS on tolling agreement from an agricultural partnership with Central Paulista Ltda. Açúcar e Álcool; (c) assessment notice related to the ICMS offset arising from the fact that the forward presumed profit is bigger than the consummated profit, under tributary substitution regime.

(iii) The amounts that have been provisioned are mainly related to social security contributions levied on company´s earnings, pursuant to Article 22-A of the 8.212/91 Law, which are being challenged on the grounds of constitutionality.

Other		1,040,422		992,682
		11,065,830		10,552,699

(i) In summary, these demands relate basically:

• Tax assessments issued against the Company for unpaid ICMS and non-compliance with accessory obligations, in connection with the agricultural and industrial tolling services partnership in specified periods between May and December of 2006 and 2007. In these cases the company is jointly and severally liable;

• ICMS levied on the remittances for the export of crystallized sugar, which the Company understands are tax exempt. However, the tax authorities classify crystallized sugar as a semi-finished product, which is therefore subject to ICMS;

• ICMS withholding rate differences on the sale of ethanol to companies located in other states, which subsequently had their tax registrations revoked;

• Disallowance of ICMS tax credits on the sale of diesel fuel to customers engaged in the agro industrial business.

• ICMS payments on inventory differences arising from erroneous calculations by the State Tax Administration;

• ICMS related to the fiscal war between the states;

• The subsidiary CLE has been discussing administratively the ICMS tax credits arising from the transfer of excess credits to its centralizing unit in the period from May 2012 to January 2013.

• The State Tax Administration assessed the rail concessions for non-taxation of ICMS on invoices for the provision of rail freight services for export. There is a favorable position for taxpayers in the higher courts; and

• Assessment from State Tax Administration of São Paulo on the grounds that the Company was not authorized to operate as a general warehouse in that state. At the time of the release of the state registration, the tax authorities allowed the Company’s activities, including issuance of invoices.

Tax assessment notice issued by the São Paulo State Treasury Department, against Rumo Malha Paulista, covering the period from February 2011 to July 2015, with the indication of infractions for alleged lack of payment of ICMS on railroad services for export and ICMS credits accrual considered undue.

(ii) Tax assessment notices issued requiring additional income tax, social contribution, PIS and COFINS, for the calendar years 2005 to 2008 as a result of the following alleged violations: (a) improper exclusion of financial costs arising from loans with foreign financial institutions from the corporate income tax and social contribution calculation basis, (b) improper exclusion of financial income from securities issued by the Government of Austria and the Government of Spain from the corporate income tax and social contribution calculation basis (c) no inclusion, in the corporate income tax and social contribution calculation basis, of gains earned in swap operations, and non-taxation of financial income resulting from these contracts by PIS and COFINS, (d) improper offsetting from corporate income tax and the social contribution calculation basis by using PIS and COFINS credits.

A favorable decision in the Administrative Court (CARF) may change its classification for remote losses.

(iii) The Company, and its controlled companies, received assessment notices based on the following: (a) tax benefits that arose from the deduction of goodwill amortization, (b) exchange variation and interest incurred as the tax authorities understand that the corporate transactions carried out were intended to postpone the settlement of debt contracted abroad through the issuance of Perpetual Bonds, in order to reduce Positive result of exchange variation, and (c) the subsidiary Comgás was known of the no recognition of the offsetting procedures made in 2015, using income taxes credits (IRPJ);

(iv) Refers mainly to the reversal of PIS and COFINS credits, provided by Laws 10.637/2002 and 10.833/2003, respectively. Those reversals arise from a differing interpretation of the laws by the tax authorities in relation to raw materials. These discussions are still at the administrative level.

Tax authorities assessed the Rumo Malha Paulista for non-taxation of PIS and COFINS on revenues from mutual traffic and rite of passage billed against Rumo Malha Norte. The chance of loss is considered possible as tax already has been collected by the concessionaire responsible for transporting from origin.

(v) The subsidiary CLE received an assessment notice related to the withholding income tax on an alleged capital gain arising from the acquisition of assets of foreign companies.

The subsidiary Comgás received an assessment notice related to the withholding income tax on an alleged capital gain of a former shareholder due to contractual arrangements.

Rumo Malha Paulista had part of its IRPJ credit balance glossed based on the argument that the Company would not be entitled to IRRF compensation on swap transactions.

(vi) The legal proceeding related to INSS payment with possible unfavorable outcome involve the following: (a) the legality and constitutionality questioning Normative Instruction MPS/SRP Nº 03/2005, which restricted the constitutional immunity over social contributions on export revenues through direct sales, consistent with the manner exports made via trading companies are now taxed; (b) assessment of SENAR (Rural apprenticeship scheme) social contribution on direct and indirect exports, in which the tax authorities disregard the right to constitutional immunity;

(vii) Legal demands related to the SRF Normative Instruction no. 67/98 that allowed for the refunding of IPI tax payments for sales of refined sugar from January 14, 1992 through November 16, 1997.

(viii) Tax assessment issued by the Brazilian Tax Authority in 2011 and 2013 against Rumo S.A. concerning: (a) amortization expense disallowance based on future profitability, as well as financial expenses; and (b) non-taxation of supposed capital gain on disposal of equity interest in a Company of the same group.

(ix) The Company was assessed due to the disregard of the tax benefits of REPORTO (PIS and COFINS suspension), on the grounds that the locomotives and freight cars purchased in 2010 were used outside the limits area of the port. Therefore, the Company was assessed to pay PIS and COFINS, as well as an isolated fine corresponding to 50% of the value of acquired assets.

(x) SRF Normative Instruction no. 67/98 allowed for the refunding of IPI tax payments for sales of refined sugar from January 14, 1992 through November 16, 1997. Consequently, the Company applied for the offsetting of amounts paid during the periods against other tax liabilities. However, the tax authorities denied its application for both the reimbursement and offsetting of these amounts. The Company has challenged this ruling in an administrative proceeding.

(xi) The Tax Authority partially rejected the Company requests for payment of its federal tax debts, pursuant to provisional measure n. 470 (MP 470), on the ground that the tax loss offered is not sufficient to settle the respective debts. The likelihood of loss is considered as possible since the results are indicated existed and are available for such use.

(xii) Decrease related to favorable decisions from administrative sphere.

Earnings per share

27 Earnings per share

The calculation of basic earnings per share has been made by dividing the profit attributable to shareholders of the parent by the weighted-average number of ordinary shares outstanding during the year excluding ordinary shares purchased by the company and held as treasury shares (Note 26).

The calculation of diluted earnings per share has been made by dividing the profit attributable to shareholders of the parent, adjusted to assume conversion of all dilutive potential ordinary shares at subsidiaries by the weighted-average number of shares outstanding during the year excluding ordinary shares purchased by the company and held as treasury shares (Note 26). The Company’s subsidiaries have two categories of potential dilutive effects: share options and put options. For the share options, a calculation is done to determine the effect of the dilution in the profit attributable to shareholders of the parent due the exercise of the share options at subsidiaries. For the put option, is assumed to have been converted into ordinary shares, and the profit attributable to shareholders of the parent is adjusted.

The following table sets forth the calculation of earnings per share (in thousands of Brazilian Reais, except per share amounts):

The non-controlling interests of the indirect subsidiary Brado Logística S.A. have the right to exercise a liquidity option provided for in the shareholders’ agreement signed on August 5, 2013. This option would exchange all Brado shares held by such minority shareholders by shares of Rumo. The exchange ratio shall take into account the economic value for both Brado and Rumo shares. At the Company’s exclusive discretion, an equivalent cash payment is also possible.

For the year ended December 31, 2017, 3,558,449 share options from indirect subsidiary Rumo S.A. and 20,621,948 share options from indirect subsidiary Brado Logística S.A. were excluded from the diluted weighted-average number of ordinary shares calculation because their effect would have been anti-dilutive.

For the year ended December 31, 2017, 11,171,300 shares related to the share repurchase plan of subsidiary Cosan S.A. have an antidilutive effect, so they were not considered in the diluted earnings per share analysis.

Risk management structure

The management has overall responsibility for the establishment and oversight of the Company’s risk management framework. The board of directors has established the Risk Management Committee, which is responsible for developing and monitoring the Company’s risk management policies. The committee reports regularly to the board of directors on its activities.

The Company’s risk management policies are established to identify and analyze the risks faced by the Company, to set appropriate risk limits and controls and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Company’s activities. The management, through its training and management standards and procedures, aims to maintain a disciplined and constructive control environment in which all employees understand their roles and obligations.

The Audit Committee oversees how management monitors compliance with the Company’s risk management policies and procedures, and reviews the adequacy of the risk management framework in relation to the risks faced by the Company. The Audit Committee is assisted in its oversight role by Internal Audit. Internal Audit undertakes both regular and ad hoc reviews of risk management controls and procedures, the results of which are reported to the Audit Committee.

All derivative activities for risk management purposes are carried out by specialist teams that have the appropriate skills, experience and supervision. It is the Company’s policy that no trading in derivatives for speculative purposes may be undertaken.

The usage of financial instruments in order to protect against these areas of volatility is determined through an analysis of the risk exposure that management intends to cover.

As at December 31, 2017 and December 31, 2016, the fair values relating to transactions involving derivative financial instruments to protect the Company’s risk exposure were using observable inputs such as quoted prices in active markets, or discounted cash flows based on market curves, and are presented below:

	Notional				Fair value

Credit risk

	December 31, 2017		December 31, 2016
Cash and cash equivalents(i)		4,555,177		4,499,588
Trade receivables(ii)		1,322,420		1,185,430
Derivative financial instruments(i)		1,162,213		751,080
Marketable securities (i)		3,853,343		1,291,580
Receivables from related parties (ii)		199,814		242,257
Dividends		13,466		144,160
Restricted cash (i)		225,634		200,999
		11,332,067		8,315,094

(i) The credit risk on cash and cash equivalents, marketable securities, restricted cash and derivative financial instruments are determined by rating instruments widely accepted by the market and are arranged as follows:

	December 31, 2017		December 31, 2016
AAA		3,499,345		—
AA		6,159,553		5,499,565
A		—		983,384
B		2,007		—
BB+		4,180		—
BBB		—		260,298
		9,665,085		6,743,247

Credit risk from balances with banks and financial institutions is managed by the Company’s treasury department in accordance with the Company’s policy. Investments of surplus funds are made only with approved counterparties and within credit limits assigned to each counterparty. Counterparty credit limits are reviewed on an annual basis and may be updated throughout the year. The limits are set to minimize the concentration of risks and therefore mitigate financial loss through potential counterparty’s failure to make payments.

(ii) Customer credit risk is managed by each business unit subject to the Company’s established policy, procedures and control relating to customer credit risk management. Credit quality of the customer is assessed based on an extensive credit rating scorecard and individual credit limits are defined in accordance with this assessment. Outstanding customer receivables are regularly monitored and any shipments to major customers are generally covered by letters of credit or other forms of credit insurance.

The requirement for impairment is analyzed at each reporting date on an individual basis for major clients. Additionally, a large number of minor receivables are grouped into homogenous groups and assessed for impairment collectively. The calculation is based on actual incurred historical data.

The maximum exposure to credit risk at the reporting date is the carrying value of each class of financial assets. Management considers that the credit risk is covered by the allowance for doubtful accounts.

Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Company’s approach to managing liquidity is to ensure, as far as possible, that it will have sufficient liquidity to meet its liabilities when they are due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Company’s reputation. As mentioned in Note 1, Management has been working on measures to enable the subsidiary Cosan Logística to honor its Commitments.

The non-derivative financial liabilities of the Company sorted by due dates (based on undiscounted cash flows contracted) are as follows:

	December 31, 2017															December 31, 2016

Market risk

Market risk is the risk that changes in market prices – such as foreign exchange rates, interest rates and equity prices – will affect the Company’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return.

The Company uses derivatives to manage market risks. All such transactions are carried out within the guidelines set by the Risk Management Committee. Generally, the Company seeks to apply hedge accounting to manage volatility in profit or loss.

a) Foreign exchange risk

As at December 31, 2017 and December 31, 2016, the Company and its subsidiaries had the following net exposure to the exchange rate variations on assets and liabilities denominated in Dollar:

	December 31, 2017			December 31, 2016
Cash and cash equivalents		782,103			424,334
Trade receivables		25,797			11,940
Advances to suppliers		—			58,866
Trade payables		(13,230	)		(22,005	)
Loans, borrowings and debentures		(8,919,712	)		(6,323,330	)
Advances from clients		(6,310	)		—
Contingent consideration		(64,213	)		(68,388	)
Payables to related parties		(210,497	)		—
Derivative financial instruments (i)		7,323,116			6,413,619
Foreign exchange exposure, net		(1,082,946	)		495,036

(i) These balances are equivalent to the notional amount in US Dollars converted to R$ at the Dollar rate of December 31, 2017 and December 31, 2016 respectively.

Sensitivity analysis on changes in foreign exchange rates:

The probable scenario was defined based on the U.S. Dollar market rates as at December 31, 2017, which determines the fair values of the derivatives at that date. Stressed scenarios (positive and negative effects, before tax effects) were defined based on changes of a 25% and 50% to the U.S. Dollar exchange rates used in the probable scenario.

Based on the financial instruments denominated in U.S. Dollars at December 31, 2017, the Company performed a sensitivity analysis by increasing and decreasing the exchange rate for R$/US$ by 25% and 50%. The probable scenario considers the estimated exchange rates, made by a specialized third part, at the due date of the transactions for the companies with functional currency Real (positive and negative, before tax effects), as follows:

	Exchange rate sensitivity analysis (R$/US$)
	December 31, 2017		Scenario
			Probable		25%		50%		-25%		-50%
US$		3.3080		3.4000		4.2500		5.1000		2.5500		1.7000

The external source used by the company for market projections was a specialized consultant.

Considering the above scenario the profit or loss would be impacted as follows:

					Variation scenario
Instrument	Risk factor	Probable			25%			50%			-25%			-50%

(i) For sensitivity analysis, it’s only considered exchange rate swaps for Notional.

b) Interest rate risk

The Company and its subsidiaries monitor the fluctuations in variable interest rates in connection with its borrowings, especially those that accrue interest using LIBOR, and uses derivative instruments in order to minimize variable interest rate fluctuation risks.

Sensitivity analysis on changes in interest rates:

A sensitivity analysis on the interest rates on loans and borrowings in compensation for the CDI investments with pre-tax increases and decreases of 25% and 50% is presented below:

	December 31, 2017
Exposure interest rate(i)	Probable			25%			50%			-25%			-50%

Financial instruments fair value

The fair values of the financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The following methods and assumptions were used to estimate the fair values:

• The cash and cash equivalents, accounts receivable, trade receivables, trade payables and other current liabilities approximate their carrying amount largely due to the short-term maturity of these instruments.

• The fair values of the quoted notes and bonds are based on price quotations at the reporting date. The fair value of unquoted instruments, loans from banks and other financial liabilities, obligations under finance leases, as well as other non-current financial liabilities is estimated by discounting future cash flows using rates currently available for debt on similar terms, credit risk and remaining maturities.

• The market value of the Senior Notes are listed on the Luxembourg Stock Exchange (Note 17) is based on their quoted market price are as follows:

Senior Notes Due	Company	December 31, 2017	December 31, 2016
2018	Cosan S.A.	100.37%	95.68%
2023	Cosan S.A.	101.54%	96.05%
2024	Rumo S.A.	107.86%	—
2027	Cosan S.A.	108.14%	100.65%
2024	Cosan	102.79%	—

• The fair value of Perpetual Notes listed on the Luxembourg Stock Exchange (Note 17) is based on their quoted market price as December 31, 2017 of 102.83% (100.03% at December 31, 2016) of the face value of obligations at December 31, 2017.

• The fair value of other loans and financing, the respective market values substantially approximate the amounts recorded due to the fact that these financial instruments are subject to variable interest rates (Note 17).

The Company and its subsidiaries enter into derivative financial instruments with various counterparties, principally financial institutions with investment grade credit ratings. Derivatives valued using valuation techniques with observable market data refer mainly to interest rate swaps and foreign exchange forward contracts.

The fair value of derivative financial instruments is determined using valuation techniques and observable market data. The valuation techniques applied more often include pricing models and swaps contracts, with a present value calculation. The models consider various data, including counterparty credit quality, spot exchange rates, forward curves of interest rates and curves of the commodity term rates.

The Company annually evaluates the credit risk of its counterparties and a possible impact on the fair value of debts and derivatives. In most cases, since the Company is a borrower, the result, in addition to immaterial, reduces its liabilities.

In order to measure the credit risk of the parties involved in the derivative instruments, the Company uses the forward rate structure disclosed by B3 and adds discount rates that reflect the risk counterparty credits that are applied to each of the maturities in the calculation of the fair value of all financial instruments. The Company adopts counterparty ratings for positive flows and its own rating for negative flows, available on the market and disclosed by renowned rating agencies, as a necessary premise to extract the probability of default.

The carrying amounts and fair value of financial assets and financial liabilities are as follows:

							Assets and liabilities measured at fair value

(i) The valuation of the contingent consideration considers the present value of expected payment, discounted using a risk-adjusted discount rate. The expected payment is determined by considering the probable scenarios of forecast revenue and EBITDA, the amount to be paid under each scenario and the probability of each scenario. The significant unobservable inputs are the forecast of the annual growth rate of revenue, EBITDA margin forecast and the 13% discount rate adjusted for risk.

Hedge accounting

Currently the Company has adopted the hedge accounting of fair value for some its operations that both the hedging instruments and the hedged items are accounted for at fair value through profit or loss. Operations and accounting effects of this adoption are as follows:

	Debt			Derivative			Total
At January 1, 2017		1,534,072			(146,697	)		1,387,375
Initial measurement		2,461,836			—			2,461,836

At December 31, 2017		4,218,221			(146,524	)		4,071,697

In May 2017 the indirect subsidiary Comgás designated hedge accounting of fair value for its “Debentures 5ª issuance” loan agreement. Using derivative operations, Comgás protected its future cash flow by changing the interest risk linked to the IPCA (National Wide Consumer Price Index) by percentages of the CDI (Interbank deposit rate).

Capital management

The Company’s policy is to maintain a robust capital base to promote the confidence of investors, creditors and the market, and to ensure the future development of the business. Management monitors that the return on capital is adequate for each of its businesses.

Increase in pension plans		4.00	%		4.50	%		4.00	%		4.50	%

Sensitivity analysis

Changes in the discount rate for the balance sheet date in one of the relevant actuarial assumptions, while maintaining other assumptions, would have affected the defined benefit obligation as shown below:

	Discount rate
	Increase			Decrease
	0.05%			0.05%
Futura		(21,739	)		23,800
Futura II		(93	)		98
Comgás		(27,459	)		30,977

There was no change in relation to previous years in the methods and assumptions used in preparing the sensitivity analysis.

The plans have been administered by the Board of Directors of each Company and its subsidiaries, at its option, by a Committee, within the limits established in the guidelines for the elaboration and structuring of each plan and in the applicable legislation.

34.1 Stock option plan

The number of options granted in the stock option plan is determined by the Board of Directors or specific Committee, with the option exercise price equivalent to the average closing price of the share in the last thirty three B3 trading sessions prior to the date of grant (“Grant date”). The exercise price is updated monthly by the variation of the Extended Consumer Price Index (“IPCA”) between the grant date and the month prior to the notification of exercise of the option by the beneficiary.

The vesting period and the position of the outstanding options are as follows:

Share option programs	Expected life (years)	Interest rate—%		Expected volatility—%		Number of instruments on December 31, 2017							Market price on grant date		Exercise price at December 31, 2017		Fair value at grant date—R$(i)

Under the plan, eligible executives may be granted ordinary shares or cash, at the choice of the Company, for no cash consideration. The number of shares issued to participants in the plan is the offer amount divided by the weighted average price at which the company’s shares are traded on the B3 during the last 30 days up to and including the date of grant.

Management’s  Annual  Report  on Internal Control over Financial Reporting

The management of Cosan Limited (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting for the Company.

The 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. The 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 perception 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. Therefore even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of the changes in conditions.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, based on the criteria set forth in Internal Control - Integrated Framework 2013 issued by the Committee of Sponsoring Organization of the Treadway Commission (COSO). Based on that assessment management has concluded that as of December 31, 2017, the Company’s internal control over financial reporting is effective.

Management assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017 has been audited by KPMG Auditores Independentes, the Company’s independent registered public accounting firm, as stated in their report which appears herein.

Statement of compliance

2.1 Statement of compliance

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

The relevant information of the financial statements, and only them, are being evidenced and correspond to those used by management in its management.

These consolidated financial statements were authorized for issue by the Board of Directors on February 22, 2018.

Certain amounts of the comparative balances, in the statements of profit or loss, statements of cash flows and in the notes 9, 11, 12, 13, 17, 18, 20, 22, 23 and 31, were reclassified to improve the level of details of disclosures in the financial statements. These reclassifications had inconsequential impacts on the Company´s financial statements.

Functional and presentation currency

2.2 Functional and presentation currency

The consolidated financial statements are presented in Brazilian Reais. However, the functional currency of Cosan Limited is the U.S. Dollar (U.S.$). The Brazilian Real is the functional currency of Cosan S.A., Cosan Logística, its subsidiaries and joint ventures, located in Brazil, as it is the currency of the primary economic environment in which they operate, generate and expend cash. The main functional currency for the subsidiaries located outside Brazil is U.S. Dollar or the Pound Sterling (GBP).

Use of judgments and estimates

2.3 Use of judgments and estimates

The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue and expenses at the end of the reporting period. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized prospectively. Information about critical judgments, assumptions and estimation uncertainties in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes:

• Notes 15 and 16 – Property, plant and equipment and intangible assets

The Company performs annually a review of impairment indicators for intangible assets with defined useful lives and property, plant and equipment. Also, an impairment test is undertaken for goodwill and intangible assets with indefinite useful lives. Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs to sell and its value in use. The key assumptions used to determine the recoverable amount of the different cash generating units to which goodwill is allocated are explained in note 16.

The subsidiary Comgás has an agreement for the public concession of gas distribution service which the Conceding Authority controls what services must be rendered and what prices will be applied, as well as included significant interest in the infrastructure at the end of the concession. This concession agreement represents the right to charge customers for the supply of gas during the effective period of the agreement. Therefore, the Company recognizes this right as intangible assets.

Thus, the infrastructure construction necessary for gas distribution is considered a service to the Grantor and the related revenue is recognized at fair value. Financing costs directly related to construction are also capitalized.

The Company does not recognize a margin on the infrastructure construction.

Subject to approval of the Granting Authority, the Company may request only once the extension of the distribution services for another 20 years. When the concession is terminated, the assets linked to the rendering of gas distribution services will be returned to the Granting Authority, and the Company will be entitled to receive an indemnity to be determined based on assessments and evaluations to be calculated at the time. Currently the figures for compensation are not predetermined or determinable, which is why the Company did not apply the bifurcated model for the accounting of financial assets.

The amortization of intangible assets reflects the pattern expected for the utilization of the future economic benefits by the Company, which corresponds to the useful lives of the assets comprising the infrastructure consonant to the São Paulo State Sanitation and Energy Regulatory Agency (“ARSESP”) provisions, as disclosed in note 16.

The amortization of the intangible assets is discontinued when the related asset is fully used or written off, and no longer is included in the calculation basis of the tariff for the rendering of the concession services, whichever occurs first.

The subsidiary Rumo has a concession rights generated in the business combination of ALL, which was fully allocated to Rumo Malha Norte concession and amortized on the straight-line method based on estimated useful lives of intangible assets, from the date on which these are available for use.

• Note 18 – Operating lease commitments

The Company contracted commercial leases of locomotives and wagons. The classification of the lease as operational or financial is determined based on an evaluation of the terms and conditions of the contracts. The Company identified the cases in which it assumes substantially all the risks and benefits of ownership of the said assets, recording such cases as a financial lease.

• Note 23 – Income taxes and social contribution

A deferred tax asset is recognized for loss carryforwards to the extent that it is probable that future taxable income will be generated to realize such losses. Significant judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the timing and the level of future taxable income together with future tax planning strategies.

• Other non-current assets

The subsidiary Comgás has natural gas supply contracts with specific characteristics, such as minimum withdrawal obligations by the Comgás (take or pay for commodity and ship or pay for transportation), that is, if Comgás consumes below contractual obligations, it must make payment of the differences between the volume consumed and the minimum contracted volumes, and may compensate them (through consumption) over the period of validity of the respective contract, provided that consumption exceeds the contracted minimum quantity. In addition, the supplier allows in contractual clause that there is recovery of the volume eventually accumulated for the term of 365 days after the termination of the contracts.

Therefore, it is currently forecast to recover all the cumulative volume since, during the recovery period provided for in the agreement, there will be no new accumulation related to the minimum commitments contracted for this period. Given the recoverable nature of this inventory, the amounts paid and not used were recognized in assets under “Paid and unused transportation.”

• Note 32 – Fair value of derivatives and other financial instruments

When the fair value of financial assets and liabilities cannot be derived from active markets, their fair value is determined using valuation techniques including the discounted cash flow model. The inputs to these models are taken from observable markets where possible, but when this is not feasible, a degree of judgment is required in determining fair values. Judgment is required in the determination of inputs such as liquidity risk, credit risk and volatility. Changes in these variables could affect the reported fair value of financial instruments.

• Note 33 – Post-employment benefits

The cost of defined benefit pension plans and other post-employment and the present value of the pension obligation is determined using actuarial valuations. An actuarial valuation involves the use of various assumptions which may differ from actual results in the future. These include the determination of the discount rate, future salary increases, mortality rates and future pension increases. A defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed by management at each reporting date.

• Note 34 – Share-based payments

The Company measures employees’ share-based compensation cost by referencing the fair value of the shares at the grant date. The estimation of fair value for share-based payment transactions requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the plan. This estimate also requires determining the most appropriate inputs to the valuation model including the assumption of the expected life of the stock option or stock grant, volatility and dividend yield. The assumptions and models used for estimating fair value for share-based payment transactions are disclosed in Note 34.

• Note 24 – Provisions for legal proceedings

Provisions for legal proceedings are recognized as other expenses when the Company has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated.

The assessment of probability loss includes the available evidence, hierarchy of laws, jurisprudence, the most recent court decisions and relevance in the legal system, as well as the opinion of outside counsel. Provisions are reviewed and adjusted according to circumstances, such as limitation period, conclusions of tax inspections or additional exposures identified based on new matters or court decisions.

Provisions for legal proceedings resulting from business combinations are estimated at fair value.

• Note 14—Investment in joint ventures

The Company has a 50% interest in a joint agreement. The joint venture agreements require unanimous consent from all parties for all relevant activities.

The two partners have direct rights to the assets of the partnership and are jointly and severally liable for the liabilities incurred by the partnership. This entity is therefore classified as a joint ventures and the Company recognizes its interest in the joint ventures using the equity method as described in Note 14.

Measurement of fair value

A number of the Company’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities.

The Company regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the valuation team assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of the accounting practices adopted in Brazil and the international standards IFRS, including the level in the fair value hierarchy in which such valuations should be classified.

When measuring the fair value of an asset or a liability, the Company uses observable market data when available. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:

• Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

• Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Company recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Basis of measurement

2.4 Basis of measurement

The consolidated financial statements have been prepared on the historical cost basis except for the following material items in the consolidated statement of financial position:

• financial instruments at fair value through profit or loss;

• derivative financial instruments at fair value through profit or loss;

• loans measured at fair value through profit or loss;

• available-for-sale financial assets are measured at fair value;

• contingent consideration assumed in a business combination;

• employee’s defined benefit obligations are presented at the present value of the actuarial obligation net of the fair value of plan assets (Note 33).

(i) As of June 30, 2017, the Company increased its interest, in Comgás to 63.11% due to the capital increase arising from the partial use of the goodwill tax benefit, according to Ordinary / Extraordinary General Meeting of April 20, 2017, of the subsidiary Comgás. As a consequence, a loss in shareholders’ equity was recognized in the total amount of R$ 6,690.

According to the event stated in the note 1 Cosan S.A. increased its interest in Comgás from 63.11% to 79.87%

According to the event stated in the note 1 Company decreased its interest in Cosan S.A. from 62.29% to 58.21%

(ii) The Company recorded in the year ended December 31, 2017, a put option for the repurchase of shares of non-controlling shareholders, according to the shareholder agreement.

(iii) The direct subsidiary Cosan S.A. has a financial investment of 26,732,274 shares of Rumo S.A., which is an indirect subsidiary of the Company. Therefore, for the consolidated financial statements of the Company, the interest of 1.71% (0.86% stake as of December 31, 2016) in the share capital of Rumo S.A. is recognized as an equity investment.

(iv) Management has concluded that there are no material uncertainties that cast doubt on the continuity of the subsidiaries. Although they had a combined amount of uncovered liabilities of R$ 92,823 as of December 31, 2017, no events or conditions were identified that individually or collectively could raise significant doubts related to their ability to maintain their operational continuity. The subsidiaries have the financial support of the Company.

(v) Interest acquired in the companies during the year 2017.

(vi) On December 22, 2017, Rumo S.A. sold the interest on ALL Rail Management Ltda. to Qualytpar Participações S.A.

(a) Business combinations

Business combinations are accounted for using the acquisition method. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired and liabilities assumed. Any goodwill that arises is tested annually for impairment. Transaction costs are expensed as incurred, except if related to the issue of debt or equity.

The consideration transferred does not include amounts related to the settlement of pre-existing relationships. Such amounts are generally recognized in profit or loss.

(b) Non-controlling interests

For each business combination, the Company elects to measure any non-controlling interests in the acquisition either:

• at fair value; or

• at their proportionate share of the acquirer’s identifiable net assets, which are generally at fair value.

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions – that is, as transactions with the owners in their capacity as owners.

(c) Subsidiaries

Subsidiaries are all entities over which the Company has control. Subsidiaries are fully consolidated from the date of acquisition of control, and continue to be consolidated until the date that control ceases to exist. They are deconsolidated from the date that control ceases.

The financial statements of subsidiaries are prepared for the same reporting period as that of the parent company, using consistent accounting policies.

(d) Investments in associates (equity method investees)

Associates are those entities in which the Company has significant influence, but not control or joint control, over the financial and operating policies.

Investments in associates are accounted for under the equity method and are recognized initially at cost. The cost of the investment includes transaction costs.

Under the equity method of accounting, the share attributable to the Company of the profit or loss for the period of such investments is accounted for in the statement of profit or loss, in “Equity in investees.” Unrealized gains and losses arising on transactions between the Company and the investees are eliminated based on the percentage of interest held in such investees. The other comprehensive income of subsidiaries, associates and jointly controlled entities is recorded directly in the Company’s shareholders’ equity, in “Other comprehensive income.”

(e) Investments in joint ventures (equity method investees)

The Company has interests in joint ventures, in which contractual arrangement establishes joint control over the voting and economic activities of the entity. The contractual arrangements require unanimous agreement for financial and operating decisions among the ventures. The Company recognizes its interest in the joint ventures using the equity method (Note 14).

(f) Transactions eliminated on consolidation

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements.

Unrealized gains arising from transactions with equity accounted investees are eliminated against the investment to the extent of the Company’s interest in the investee. Unrealized losses are similarly eliminated, but only to the extent that there is no evidence of impairment.

Foreign currency

3.2 Foreign currency

a) Foreign currency transactions

Transactions in foreign currencies are translated to the respective functional currencies of each subsidiary using the exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are translated to the functional currency using the exchange rate at the reporting date.

b) Foreign operations

The assets and liabilities derived from foreign operations, including goodwill and fair value adjustments arising on acquisition, are translated to Brazilian Reais using the exchange rates at the reporting date. Income and expenses of foreign operations are translated to Brazilian Reais using the exchange rates at the dates of the transactions.

Foreign currency differences are recognized in other comprehensive income, and presented in the foreign currency translation reserve (translation reserve) in equity. However, if the foreign operation is a non-wholly owned subsidiary, then the relevant proportion of the translation difference is allocated to non-controllinginterests. When a foreign operation is disposed of such that control, significant influence or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal.

c) Translation of subsidiaries and associates’ financial statements

These consolidated financial statements have been translated to the Brazilian Real using the following criteria:

(a) assets and liabilities have been translated using the exchange rate at the balance sheet date;

(b) statement of profit or loss, comprehensive income and statement of cash flows have been translated using the monthly average exchange rate; and

(c) shareholders’ equity has been translated using the historical exchange rate.

Translation effects have been recognized in shareholders’ equity in “Cumulative translation adjustment.”

The consolidated financial statements of each subsidiary included in these consolidated financial statements and equity method investments are prepared based on their respective functional currencies. For subsidiaries whose functional currency is a currency other than the Brazilian Real, asset and liability accounts are translated into the Company’s reporting currency using exchange rates in effect at the date of the statement of financial position, and income and expense items are translated using monthly average exchange rates and shareholders’ equity has been translated using the historical exchange rate. The resulting translation adjustments are reported in a separate component of shareholders’ equity, as cumulative translation adjustment.

The exchange rate of the Brazilian Real (R$) to the U.S. Dollar (U.S.$) was R$ 3.3080 at December 31, 2017, R$ 3.2591 at December 31, 2016 and R$ 3.9048 at December 31, 2015.

Financial instruments

3.3 Financial instruments

(i) Non-derivative financial assets

The Company initially recognizes loans and receivables on the date that they are originated. All other financial assets (including assets designated as at fair value through profit or loss) are recognized initially on the trade date, which is the date that the Company becomes a party to the contractual provisions of the instrument.

The Company classifies non-derivative financial assets into the following categories: financial assets at fair value through profit or loss, held-to-maturity financial assets, loans and receivables.

a) Financial assets at fair value through profit or loss

A financial asset is classified at fair value through profit or loss if it is classified as held-for-trading or is designated as such on initial recognition. Financial assets are designated at fair value through profit or loss if the Company manages such investments and makes purchase and sale decisions based on their fair value in accordance with the Company’s documented risk management or investment strategy. Attributable transaction costs are recognized in profit or loss as incurred. Financial assets at fair value through profit or loss are measured at fair value and changes therein, which takes into account any dividend income, are recognized in profit or loss.

i. Marketable securities

Investments in securities with a maturity date greater than three months at the date of purchase and other securities for which there is more than an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal

b) Loans and receivables

Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Such assets are recognized initially at fair value plus any directly attributable transaction costs. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method, less any impairment losses.

Loans and receivables comprise cash and cash equivalents, restricted cash , trade and other receivables.

Cash and cash equivalents

Cash and cash equivalents comprise cash balances, call deposits and highly liquid short-term investments with maturities of three months or less from the acquisition date that are subject to an insignificant risk of changes in their fair value, and are used by the Company in the management of its short-term commitments.

c) Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial assets that are designated as available-for-sale or are not classified in any of the above categories of financial assets. Available-for-sale financial assets are recognized initially at fair value plus any directly attributable transaction costs.

Subsequent to initial recognition, the financial assets are measured at fair value and changes therein, other than impairment losses and foreign currency gain/losses on available-for-sale debt instruments, are recognized in other comprehensive income and presented in the consolidated statements of changes in equity. When an investment is derecognized, the gain or loss accumulated in equity is reclassified to profit or loss.

Derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when:

• The rights to receive cash flows from the asset have expired; or

• 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 (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and, to what extent, it has retained the risks and rewards of ownership.

When it has neither transferred nor retained substantially all of the risks and rewards of the asset nor transferred control of it, the asset is recognized to the extent of the Company’s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

(ii) Non-derivative financial liabilities

The Company initially recognizes debt securities issued and subordinated liabilities on the date that they are originated. All other financial liabilities are recognized initially on the trade date, which is the date that the Company becomes a party to the contractual provisions of the instrument.

The Company derecognizes a financial liability when its contractual obligations are discharged, cancelled or expire.

The Company classifies non-derivative financial liabilities, except contingent consideration, as other financial liabilities. Such financial liabilities are initially recognized at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these financial liabilities are measured at amortized cost using the effective interest method.

Financial liabilities comprise loans and borrowings, debt securities issued, bank overdrafts, and trade and other payables.

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires.

When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the statement of profit or loss.

(iii) Share capital

Ordinary shares

Incremental costs directly attributable to the issue of ordinary shares are recognized as a deduction from equity. Income taxes relating to transaction costs of an equity transaction are accounted for in accordance with IAS 12.

Preference shares

Non-redeemable preference shares are classified as equity, because they bear discretionary dividends, do not contain any obligations to deliver cash or other financial assets and do not require settlement in a variable number of the Company’s equity instruments. Discretionary dividends thereon are recognized as equity distributions on approval by the Company’s shareholders.

Mandatory minimum dividends as defined in the bylaws are recognized as liabilities.

(iv) Derivative financial instruments, including hedge accounting

The Company holds derivative financial instruments to hedge its foreign currency and interest rate risk exposures. Embedded derivatives are separated from the host contract and accounted for separately if:

(a) The economic characteristics and risks of the host contract and the embedded derivative are not closely related;

(b) A separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

(c) The combined instrument is not measured at fair value through profit or loss.

On initial designation of the derivative as a hedging instrument, the Company formally documents the relationship between the hedging instrument and hedged item, including the risk management objectives and strategy in undertaking the hedge transaction and the hedged risk, together with the methods that will be used to assess the effectiveness of the hedging relationship. The Company makes an assessment, both at the inception of the hedge relationship as well as on an ongoing basis, of whether the hedging instruments are expected to be highly effective in offsetting the changes in the fair value or cash flows of the respective hedged items attributable to the hedged risk, and whether the actual results of each hedge are within a range of 80% – 125%. For a cash flow hedge of a forecast transaction, the transaction should be highly probable to occur and should present an exposure to variations in cash flows that ultimately could affect reported profit or loss.

Derivatives are initially recognized at fair value; any attributable transaction costs are recognized in profit or loss as incurred. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are accounted for as described below:

• Cash flow hedges

When a derivative is designated as the hedging instrument in a hedge of the variability in cash flows attributable to a particular risk associated with a recognized asset or liability or a highly probable forecast transaction that could affect profit or loss, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income and presented in the hedging reserve in equity. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss.

When the hedged item is a non-financial asset, the amount accumulated in equity is retained in other comprehensive income and reclassified to profit or loss in the same period or periods during which the non-financial item affects profit or loss. If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated or exercised, or the designation is revoked, then hedge accounting is discontinued prospectively. If the forecast transaction is no longer expected to occur, then the balance in equity is reclassified to profit or loss.

• Fair value hedge

Changes in fair value of derivatives, that are designated and qualify as fair value hedge, are recorded in the statement of profit or loss, with any changes in fair value of the hedged asset or liability that are attributable to the hedged risk. The Company applies hedge accounting for fair value hedges to protect itself against the risk of changes in interest rates and foreign exchange rates on loans. The gain or loss related to the effective portion of interest rate swaps to protect against fixed rate borrowings is recognized in the statement of profit and loss as “Financial expenses.” The gain or loss related to the ineffective portion is recognized in the statement of profit or loss as “Other gains (losses), net.” Changes in fair value of fixed rate borrowings hedged attributable to interest rate risk are recognized in the statement of profit or loss as “Financial expenses.”

If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the method of effective interest rate is used, is amortized to income over the period to maturity.

• Embedded derivatives

Changes in the fair value of separated embedded derivatives are recognized immediately in profit or loss.

• Other derivative financial instruments

When a derivative financial instrument is not designated in a hedge relationship and does not qualify for hedge accounting, all changes in its fair value are recognized immediately in profit or loss.

Inventory

3.4 Inventory

Inventory is recorded at the lower of average cost of acquisition or production and net realizable value, whichever the less.

Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

Provisions for slow-moving or obsolete inventory are recorded when deemed necessary by management. The cost of finished goods and work in progress comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). It excludes borrowing costs.

Property, plant and equipment

3.5 Property, plant and equipment

(a) Recognition and measurement

Items of property, plant and equipment are measured at cost less accumulated depreciation and any accumulated impairment losses.

Cost includes expenditures that are directly attributable to the acquisition of the asset. The cost of constructed assets includes:

• the cost of materials and direct labor;

• any other costs directly attributable to bringing the assets to a working condition for their intended use;

• an estimate of the costs of dismantling and removing the items and restoring the site on which they are located, when the Company has an obligation to remove the asset or restore the site; and

• capitalized borrowing costs.

Cost also includes transfers from equity of any gain or loss on qualifying cash flow hedges of foreign currency purchases of property, plant and equipment. Purchased software that is integral to the functionality of the related equipment is capitalized as part of that equipment.

When components of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

Any gain or loss on disposal of an item of property, plant and equipment, calculated as the difference between the net proceeds from disposal and the carrying amount of the item, is recognized in profit or loss.

(i) Reclassification to investment property

When the use of a property changes from held to use to investment property, the property is remeasured at fair value and reclassified as investment property. Any gain or loss arising on this remeasurement is recognized in equity.

(ii) Subsequent costs

Subsequent expenditure is capitalized only when it is probable that the future economic benefits associated with the expenditure will flow to the Company. Ongoing repairs and maintenance are expensed as incurred.

(iii) Depreciation

Items of property, plant and equipment are depreciated from the date they are available for use or, in respect of constructed assets, from the date that the asset is completed and ready for use.

Depreciation is calculated on the carrying value of property, plant and equipment less their estimated residual values using the straight-line basis over their estimated useful lives. Depreciation is generally recognized in profit or loss, unless it is capitalized as part of the cost of another asset. Assets recognized under finance leases are depreciated over the shorter of the lease term and their useful lives unless it is reasonably certain that the Company will obtain ownership by the end of the lease term. Land is not depreciated.

Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets as follows:

Buildings and improvements	4% to 5%
Machinery, equipment and facilities	8% to 11%
Airplanes, vessels and vehicles	10% to 20%
Railcars	2.9% to 6%
Locomotives	3.33% to 8%
Permanent railways	4%
Furniture and fixtures	10% to 15%
Computer equipment	20%

Costs of normal periodic maintenance are recorded as expenses when incurred when the components will not improve the production capacity or introduce improvements to the equipment.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed annually and adjusted prospectively. During the fiscal year ended December 31, 2017, the subsidiary Rumo S.A. conducted a useful life review of a group of approximately 200 locomotives allocated to the logistics segment. Locomotives comprise individual components with different useful lives, and the review resulted in a reduction of useful lives of some components to reflect the time that the subsidiary Rumo intends to use those components through its economic life. The new useful life was applied starting from January 1^st 2017.

Depreciation methods such as useful lives and residual values are reviewed at each year-end, or when there is significant change without an expected consumption pattern, such as relevant incident and technical obsolescence. Any adjustments are recognized as changes in accounting estimates, if appropriate.

Intangible assets and goodwill

3.6 Intangible assets and goodwill

(a) Goodwill

Goodwill is measured at cost less accumulated impairment losses. With respect to equity method investees, the carrying amount of goodwill is included in the carrying amount of the investment, and any impairment loss is allocated to the carrying amount of the equity method investee as a whole.

(b) Other intangible assets

Other intangible assets that are acquired by the Company and have a finite life are measured at cost less accumulated amortization and any accumulated impairment losses.

(c) Subsequent expenditure

Subsequent expenditures are capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditures are recognized in profit or loss as incurred.

(d) Amortization

Except for goodwill, intangible assets are amortized on a straight-line basis over their estimated useful lives, from the date that they are available for use or acquired.

Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(e) Contracts with customers

Costs incurred on development of gas systems for new clients (including pipelines, valves, and general equipment) are recognized as intangible assets and amortized over the contract period.

(f) Intangible assets related to the concession rights agreement

The Company has a public concession agreement for a gas distribution service in which the Concession Authority controls what services will be provided and the price, as well it holds a significant participation in the infrastructure at the end of the concession. This concession agreement represents the right to charge users for gas supply during the term of the agreement. Accordingly, the Company recognizes this right as an intangible asset

The intangible asset comprises: (i) the concession right recognized upon the business combination of Comgás, which is being amortized over the concession period on a straight line basis, considering the extension of the distribution services for another 20 years; and (ii) the acquired or constructed assets underlying the concession necessary for the distribution of gas, which is being depreciated to match the period over which the future economic benefits of the asset are expected to accrue to the Company, or the final term of the concession, whatever occurs first. This period reflects the economic useful lives of each of the underlying assets that comprise the concession. This economic useful life is also used by the regulator, The Natural Gas Agency of the State of São Paulo, to determine the basis for measuring the tariff for rendering the services under the concession.

The concession agreement was signed on May 31, 1999 with an initial term of 30 years. Subject to approval of the Conceding Authority, the Company may request only once the extension of the distribution services for another 20 years. When the concession is terminated, the assets linked to the rendering of gas distribution services will be returned to the Conceding Authority, and the Company will be entitled to receive an indemnity to be determined based on assessments and evaluations considering the book values to be calculated at the time.

The concession contract determines that the tariff charged by Comgás be reviewed annually, in May, with the aim to realign the tariff charged to consumers to the cost of the gas and adjust for inflation.

Once the concession is terminated, the Company has the right to request the reversion to the Granting Authority of the assets and facilities linked to the gas distribution service. Currently, the amounts related to indemnification are not pre-established or determinable, that’s why the Company did not apply the bifurcated model for the accounting of the financial asset.

Concession rights generated in the business combination of ALL was fully allocated to the Rumo Malha Norte concession and amortized on a straight-line basis.

Impairment

3.7 Impairment

(i) Non-derivative financial assets

A financial asset not classified as at fair value through profit or loss, including an interest in an equity-accounted investee, is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset, and that loss event(s) had an impact on the estimated future cash flows of that asset that can be estimated reliably.

(a) Financial assets measured at amortized cost

An impairment loss in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset’s original effective interest rate. Losses are recognized in profit or loss and reflected in an allowance account against loans and receivables or held-to-maturity investment securities. If, in a subsequent period, the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the statement of profit or loss.

(b) Available-for-sale financial assets

Impairment losses on available-for-sale financial assets are recognized by reclassifying the accumulated losses recorded in equity to profit or loss. The cumulative loss that is reclassified from equity to profit or loss is the difference between the acquisition cost, net of any principal repayment and amortization, and the current fair value, less any impairment loss recognized previously in profit or loss.

(ii) Non-financial assets

The carrying amounts of the Company’s non-financial assets, except investment property, inventories and deferred tax assets, are reviewed at each reporting date to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill is tested annually for impairment. An impairment loss is recognized if the carrying amount of an asset or cash-generating unit (“CGU”) exceeds its recoverable amount.

The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU. For impairment testing, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or CGUs. Subject to an operating segment ceiling test, CGUs to which goodwill has been allocated are aggregated so that the level at which impairment testing is performed reflects the lowest level at which goodwill is monitored for internal reporting purposes. Goodwill acquired in a business combination is allocated to Companies of CGUs that are expected to benefit from the synergies of the combination.

Impairment losses are recognized in profit or loss. Impairment losses recognized for CGUs are allocated first to reduce the carrying amount of any goodwill allocated to the CGU (group of CGUs), and then to reduce the carrying amounts of the other assets in the CGU (group of CGUs) on a pro rata basis.

An impairment loss with respect to goodwill is not reversed. For other assets, an impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

Provisions

3.8 Provisions

A provision is recognized if, as a result of a past event, the Company has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as finance cost.

Employee benefits

3.9 Employee benefits

• Short-term employee benefits

Short-term employee benefit obligations are measured on an undiscounted basis and are expensed when the related service is provided. A liability is recognized for the amount expected to be paid under short-term cash bonus or profit-sharing plans if the Company has a present legal or constructive obligation to pay these amounts as a result of past services provided by the employee, and the obligation can be estimated reliably.

• Share-based payment transactions

The grant-date fair value of share-based payment awards granted to employees is recognized as an employee compensation expense, with a corresponding increase in equity, over the period that the employees become unconditionally entitled to the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market performance conditions are expected to be met, such that the amount ultimately recognized as an expense is based on the number of awards that meet the related service and non-market performance conditions at the vesting date. For share-based payment awards with non-vesting conditions, the grant-date fair value of the share-based payment is measured to reflect such conditions and there is no true-up for differences between expected and actual outcomes.

The fair value of the amount payable to employees with respect to share appreciation rights, which are settled in cash, is recognized as an expense with a corresponding increase in liabilities, over the period that the employees become unconditionally entitled to the cash payment. The liability is remeasured at each reporting date and at settlement date based on the fair value of the share appreciation rights. Any changes in the liability are recognized as employee benefit expenses in profit or loss.

The accounting for modification on plans depends on whether the modification changes the classification of the arrangement and whether the changes are beneficial to the counterparty.

If a modification increases the number of equity instruments granted, then the entity recognizes the fair value of the additional equity instruments measured at the date of modification. The additional share-based payment cost is attributed over the period from the date of modification to the end of the vesting period of the additional equity instruments.

Cancellations or settlements of equity-settled share-based payments during the vesting period by the entity or by the counterparty are accounted for as accelerated vesting; therefore, the amount that would otherwise have been recognized for services received is recognized immediately.

• Defined contribution plans

A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions into a separate entity and has no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution plans are recognized as an employee benefit expense in profit or loss in the periods during which related services are rendered by employees. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in future payments is available. Contributions to a defined contribution plan that is due more than 12 months after the end of the period in which the employees render the service are discounted to their present value.

• Defined benefit plans

The Company is the sponsor of defined benefit pension plans for some of its employees. A defined benefit plan is a post-employment benefit plans other than a defined contribution plan.

The liability recognized in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method.

The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows, using interest rates that are denominated in the currency in which the benefits will be paid, and that have terms approximating to the terms of the related obligation.

Gains and losses arising from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur, directly in other comprehensive income.

Changes in the present value of the defined benefit obligation resulting from plan amendments or curtailments are recognized immediately in profit or loss as past service costs.

Some of the Company’s pension plan, even though it is substantially defined contribution, has a variable component, whose risk is linked to the payment of minimum benefit and to the increase of the future contributions of the sponsors in the benefits in the event of Death Tax of the active taxpayer as well as in Disability Retirement, limited to three salaries. Any actuarial liability calculated, is recorded by the Company.

• Other long-term employee benefit

The Company’s net obligation in respect of long-term employee benefits other than pension plans is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value, and the fair value of any related assets is deducted. The discount rate is the yield at the reporting date of the financial statements for the high credit quality bonds, and maturity dates approximating the terms of the Company’s obligations and that are denominated in the currency in which the benefits are expected to be paid. The calculation is performed using the projected unit credit method. Any actuarial gains and losses are recognized in profit or loss in the period in which they arise.

Revenue

3.10 Revenue

(a) Sales of goods

Revenue from the sale of goods, in the ordinary course of business, is measured at the fair value of the consideration received or receivable, net of returns, trade discounts and volume rebates. Revenue is recognized when significant risks and rewards of ownership have been transferred to the customer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably. If it is probable that discounts will be granted and the amount can be measured reliably, then the discount is recognized as a reduction of revenue as the sales are recognized.

(b) Services rendered

Revenues from services are recognized when the amount of revenue can be measured reliably, when it is probable that the economic benefits associated with the transaction will flow to the Company, when the stage of completion of the transaction at the end of the reporting period can be measured reliably, as well as when its amount and related costs can be measured reliably. Service prices are established based on service orders or contracts. Services for which payment is made in advance are recorded as deferred revenue in other liabilities and recognized in revenue when the services are rendered.

The Company revenue recognizes revenue as follows:

• Billed revenue

Revenue from gas distribution services is recognized when its amount can be reliably measured, and is recognized in profit or loss when the volumes are delivered to customers.

• Unbilled revenue

Unbilled gas refers to the portion of gas supplied for which metering and billing to customers have not yet occurred. This amount is estimated based on the period between measurement and the last day of the month.

The actual volume billed may be different from estimates. The Company believes that, based on its historical experience with similar operation, the unbilled estimated amount will not significantly differ from actual amounts.

• Concession construction revenue

The construction of the infrastructure necessary for gas distribution is considered a construction service rendered to the Conceding Authority, and the related income is recognized in profit or loss at finishing stage of the work.

Construction costs are recognized by reference to the stage of completion of the construction activity at the end of the reporting period, and are included in cost of sales.

(c) Deferred revenue

The Company´s deferred revenue consists in advances received from clients seeking investment in fixed assets in return for a rail service contract requiring future performance of services by the Company.

Government grants

3.11 Government grants

Government grants are recognized where there is reasonable assurance that the grant will be received and all attached conditions will be complied with. The indirect subsidiary Rumo Malha Norte has a fiscal incentive whose benefit includes a reduction of 75% on income tax based on operation profit beginning in 2008 until 2024.

Leases

3.12 Leases

The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at the inception date.

a) Leased assets

Leases of property, plant and equipment that transfer to the Company substantially all of the risks and rewards of ownership are classified as finance leases. The leased assets are measured initially at an amount equal to the lower of their fair value and the present value of the minimum lease payments. Subsequent to initial recognition, the assets are accounted for in accordance with the accounting policy applicable to that asset.

A leased asset is depreciated over the useful life of the asset. However, if there is no reasonable certainty that the Company will obtain ownership by the end of the lease term, the asset is depreciated over the shorter of the estimated useful life of the asset and the lease term.

Assets held under other leases are classified as operating leases and are not recognized in the Company’s statement of financial position.

b) Lease payments

Payments made under operating leases are recognized in profit or loss on a straight-line basis over the term of the lease. Lease incentives received are recognized as an integral part of the total lease expense, over the term of the lease.

Minimum lease payments made under finance leases are apportioned between the finance expense and the reduction of the outstanding liability. The finance expense is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability.

The amounts paid in advance by the Company are recorded as assets and allocated in income linearly during the term of the contract. The expenses incurred during the grace period are recorded in income and maintained as payables, being written off in proportion to the payment of current installments.

Finance income and finance expense

3.13 Finance income and finance expense

Finance income comprises interest income on funds invested (including available-for-sale financial assets), dividend income, gains on the disposal of available-for-sale financial assets, fair value gains on financial assets at fair value through profit or loss, gains on the remeasurement to fair value of any pre-existing interest in an acquire in a business combination, gains on hedging instruments that are recognized in profit or loss and reclassifications of net gains previously recognized in other comprehensive income. Interest income is recognized as it accrues in profit or loss, using the effective interest method. Dividend income is recognized in profit or loss on the date that the Company’s right to receive payment is established, which in the case of quoted securities is normally the ex-dividend date.

Finance expense comprise interest expense on borrowings, unwinding of the discount on provisions and deferred consideration, losses on disposal of available-for-sale financial assets, dividends on preference shares classified as liabilities, fair value losses on financial assets at fair value through profit or loss and contingent consideration, impairment losses recognized on financial assets (other than trade receivables), losses on hedging instruments that are recognized in profit or loss and reclassifications of net losses previously recognized in other comprehensive income.

Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are recognized in profit or loss using the effective interest method.

Foreign currency gains and losses on financial assets and financial liabilities are reported on a net basis as either finance income or finance cost depending on whether the net foreign currency fluctuations result in a gain or loss position.

Taxes

3.14 Taxes

Income taxes are comprised of income tax and social contribution at a combined rate of 34%. Tax expense comprises current and deferred tax. Current tax and deferred tax is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income.

Certain subsidiaries measure income tax and social contribution due under the Brazilian presumed profits regime. The presumed profit came up from a percentage of 32% of operating revenues. Under the aforementioned regime the applicable tax rate is for income tax is 15% over the presumed profit, plus an additional 10% when operating revenues exceed of R$ 240, and 9% over the presumed profit for social contribution.

a) Current tax

Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years.

b) Deferred tax

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes and tax loss. Deferred tax is not recognized for:

• temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss;

• temporary differences related to investments in subsidiaries, associates and joint ventures to the extent that the Company is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and

• taxable temporary differences arising on the initial recognition of goodwill.

The measurement of deferred tax reflects the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. For investment property that is measured at fair value, the presumption that the carrying amount of the investment property will be recovered through sale has not been rebutted.

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax rates enacted or substantively enacted at the reporting date.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realized simultaneously.

A deferred tax asset is recognized for loss carryforwards, tax credits and deductible temporary differences to the extent that it is probable that future taxable income will be generated in the future. Deferred tax assets are reviewed at each reporting date and written off to the extent that it is no longer probable that the related tax benefit will be realized.

c) Sales taxes

Net revenue is recognized net of discounts and sales taxes.

d) Tax exposures

In determining the amount of current and deferred tax, the Company takes into account the impact of uncertain tax positions and whether additional taxes and interest may be due. This assessment relies on estimates and assumptions and may involve a series of judgments about future events. New information may become available that causes the Company to change its judgment regarding the adequacy of existing tax liabilities; such changes to tax liabilities will impact tax expense in the period that such a determination is made.

Cash flow

3.15 Cash flow

• Non-cash transaction

During the year ended December 31, 2017, the Company made the following transactions not involving cash and therefore not reflected in the consolidated statement of cash flows:

(i) Forward purchase of property, plant and equipment in the amount of R$105,102.

• Disclosure of interest and dividends

(i) The Company disclosures the dividends and interest on shareholders’ equity received as cash flow from investing activities, with the purpose of avoiding distortions in its cash flows from operation activities.

(ii) Interest received or paid is classified as cash flow from financing activities, as it is considered to refer to the costs of obtaining financial resources.

(i) During the period from October 2003 to November 2006, the Company, through its subsidiary CLE, offset the FINSOCIAL tax against several other federal taxes, based on a final court decision in September 2003 following a decision that challenged the constitutionality of the FINSOCIAL. No judicial deposits were made.

(ii) The amounts that have been provisioned refer to tax assessments by the tax authorities related to several types of ICMS credits. Amongst them: (a) assessment notice related to ICMS payments for the purchase of raw materials which are considered for “use and consumption,” therefore, not eligible for compensation; (b) assessment, as sole obligor, for withholding of ICMS on tolling agreement from an agricultural partnership with Central Paulista Ltda. Açúcar e Álcool; (c) assessment notice related to the ICMS offset arising from the fact that the forward presumed profit is bigger than the consummated profit, under tributary substitution regime.

(iii) The amounts that have been provisioned are mainly related to social security contributions levied on company´s earnings, pursuant to Article 22-A of the 8.212/91 Law, which are being challenged on the grounds of constitutionality. Judicial deposits have been made for the corresponding amounts.

Concessions Payable - Additional Information (Detail)	12 Months Ended

Disclosure of Concessions Payable and Judicial Deposits [Abstract]
Description of lease agreement	In April 2005, the injunction was granted, suspending the enforceability of installments for 90 days by determining the completion of expertise. In July 2005, the suspension was extended for another 90 days. In September 2005, the injunction was overturned by the Federal Court of Rio de Janeiro. In January 2006, the suspension of payment of installments was granted, by means of judicial deposit. The amount related to the lease installments was deposited in court until October 2007, when the Company obtained a court order to replace the judicial deposits with a bank guarantee. In October 2015, a decision was handed down that partially upheld the action recognizing the occurrence of economic and financial balance of the agreements, allowing the Company to perform the part of compensation of the amounts claimed in the match against presented debt. Nevertheless, the Company believes that all amounts discussed shall be offset against payables based in clauses 7 and 10 of the bidding documents.
