To the Board of Directors and Shareholders of Braskem S.A.

We have reviewed the accompanying condensed consolidated balance sheet of Braskem S.A. and its subsidiaries (the “Company”) as of September 30, 2017, and the related condensed consolidated statements of operations and comprehensive income for the three-month and nine-month periods ended September 30, 2017 and 2016 and the condensed consolidated statements of changes in shareholder’s equity and cash flows for the nine-month periods ended September 30, 2017 and 2016. This condensed consolidated interim financial information is the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying condensed consolidated interim financial information for it to be in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

As discussed in Note 2.3 to the condensed consolidated interim financial information, the Company has restated its 2016 and 2015 financial statements to correct misstatements.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2016, and the related consolidated statement of operations, comprehensive income, of statement of changes in equity and of cash flows for the year then ended (not presented herein), and in our report dated September 22, 2017, which included a paragraph regarding the correction of an error in the 2015 and 2014 financial statements, we expressed an unqualified opinion on those consolidated financial statements.

(“Odebrecht”), which directly and indirectly holds interests of 50.11% and 38.32% in its voting and total capital, respectively.

With more than 100 clients, with approximately 70% in the Camaçari Petrochemical Complex, Cetrel is responsible for the treatment and final disposal of effluents and industrial waste, environmental monitoring and water supply for industrial use of Braskem's plants in Camaçari.

Cetrel plays an important role in the management of the environmental processes of the activities of the Camaçari Petrochemical Complex, and its acquisition seeks to guarantee the safety and reliability of the industrial operations in said Pole.

On September 29, 2017, the Shareholders Meeting of Braskem approved the consummation of the acquisition, with payment and transfer of control occurring on October 2, 2017 (Note 27(a)).

(iii) On June 21, 2017, the Board of Directors approved the construction of a new polypropylene production unit in La Porte, Texas, United States. The total investment is up to approximately US$675 million(*) for 450 kta in production capacity. The project is slated to be concluded in 2020.

(b) Net Working Capital

On September 30, 2017, in compliance with accounting standard IAS 1 (Presentation of Financial Statements), the subsidiary Braskem Idesa reclassified to current liabilities the finance obligations whose original maturities are long term, since certain contractual obligations (covenants) as of September 30, 2017 were in default (Note 14). Consequently, the net working capital became negative R$2,892,113.

It should be noted that Braskem Idesa has been settling its debt service obligations in accordance with the original maturity schedule, none of the creditors has requested immediate repayment of such obligations and, without the above reclassification, consolidated net working capital is positive at R$5,807,912.

2.3. Restatement

The statements of operations, of changes in shareholders’ equity and of cash flows for the period ended September 30, 2016 and the starting balance of equity in December 2015 were restated due to prior-year adjustments. The information related to this restatement was reported in the 2016 annual financial statements of the Company, in Note 2.4.

Furthermore, the statement of cash flows for the period ended September 30, 2016 was restated due to the reclassification of Brazilian government bonds from “cash and cash equivalents” to “financial investments” (negative variation of R$564,859 in the period ended September 30, 2016 as explained in Note 5).

2.4. Change in accounting policy

(a) The Management of Braskem decided to change, in the statement of cash flows, the presentation of interest paid, which previously was presented under the group referred to as “cash used in investment activities.” These expenses are now recorded under the item “interest paid.” This change enables: (i) the direct identification of the total amount paid as interest; and (ii) greater accuracy in determining the net cash from operations. The amounts reclassified in the period ended September 30, 2016 were R$270,235 in the consolidated cash flows.

(b) In 2017, the Company changed the classification of provision for profit sharing to standardize such classification among all companies, whether or not productive, and because it deemed the current classification more appropriate, since this provision does not present recurring elements or, even when recurring, the amounts differ from year to year.

In the period ended September 30, 2016, the consolidated amounts related to this item were reclassified from “costs of goods sold” (R$107,318), “selling and distribution expenses” (R$5,031) and “general and administrative expenses” (R$133,004) to the item “other income (expenses), net” (Note 23).

3. Non-current assets held-for-sale assets and discontinued operations

On January 9, 2017, the Board of Directors approved the sale of the subsidiaries Quantiq Distribuidora Ltda. and IQAG Armazens Gerais Ltda. to the unrelated company GTM do Brasil Comércio de Produtos Químicos Ltda. The sale agreement, in the amount of R$550 million, was signed on the following day, and in January the transaction was approved by Brazil’s antitrust agency CADE ( Conselho Administrativo de Defesa Econômica ).

The approval of the sale plan was made by Management during the second half of 2016.

The transfer of control to the acquiring company was concluded on April 3, 2017. On the same date, Braskem received R$450 million. The remaining R$100 million will be received within 12 months, subject to adjustments typical to operations of this nature. The capital gain from this operation was R$276,816 (Total consideration of R$550,000 (-) net assets of R$273,184), registered in the second quarter of 2017.

Assets and liabilities classified as available-for-sale and profit or loss from discontinued operations until the date of transfer of control are shown below:

13. Borrowings

The information on borrowings was presented in the 2016 annual financial statements of the Company, in Note 15.

(a) The Company has borrowings contracted from financial institutions and the capital markets that include contractual obligations (covenants) requiring the presentation of its audited financial statements within the legal deadline (or within 120 days from the end of the fiscal year).

In the condensed interim financial information as of June 30, 2017, the Company was in unremedied breach with regard to the presentation of audited financial statements within the legal timeframe involving government agents FINAME and FDNE in the amount of R$40,481, which were reclassified to current liabilities in accordance with IAS 1 (Presentation of Financial Statements).

In accordance with the aforementioned accounting standards, reclassification is required in situations in which the breach of certain contractual obligations entitles creditors to request the prepayment of obligations in the short term. In this context, Braskem notes that none of its creditors requested said prepayment of obligations and that it has been settling these obligations in accordance with their original maturity schedule.

The breach of said obligations was automatically remedied with the presentation of the audited financial statements in the third quarter ended September 30, 2017, with said creditors no longer entitled to request prepayment, with the respective amount reclassified from current liabilities back to non-current liabilities.

Project Finance borrowings include contractual obligations (covenants) that require, among other things, the presentation of the audited financial statements within the legal timeframe (or within 120 days from the end of the fiscal year).

On the reporting date for the condensed interim financial of September 30, 2017, the Company was in unremedied breach of its obligation to present audited financial statements within the legal timeframe, as well as of other obligations typical to contracts of this nature. As a result, the entire balance of non-current liabilities, in the amount of R$8,700,025, was reclassified to current liabilities, in accordance accounting standard IAS 1 (Presentation of Financial Statements).

In accordance with the aforementioned accounting standards, reclassification is required in situations in which the breach of certain contractual obligations entitles creditors to request the prepayment of obligations in the short term. In this context, note that none of the creditors requested said prepayment of obligations and that Braskem Idesa has been settling its debt service obligations in accordance with their original maturity schedule.

Furthermore, Braskem Idesa has been negotiating approval of such breaches with its creditors in order to reclassify the entire amount reclassified from current liabilities back to non-current liabilities.

(a) Operations designated for hedge accounting

(a.i) U.S. dollar Put Options

In September 2016, Braskem launched a recurring currency hedge program to mitigate the exposure of its cash flows to liabilities denominated in Brazilian real and not pegged to the U.S. dollar (e.g., electricity, payroll, etc.).

With the exclusive purpose of protecting cash flow, the program uses two strategies with derivative instruments: (i) purchase of put options and (ii) purchase of put options associated with the sale of call options ("Collar").

Both alternatives offer protection to Braskem if the local currency appreciates, with the difference that the Collar strategy can also result in negative adjustments to the Company if the USD/BRL exceeds the call exercise price. Eventual losses, however, will always be offset by gains in competitiveness resulting from costs in lower Reais, when observed in US Dollars.

On September 30, 2017, Braskem had total notional value purchased in puts of R$3.8 billion, at the average exercise price of 2.96 R$/US$. Concomitantly, the Company also had total notional value sold in calls of R$2.2 billion, at the average exercise price of R$4.26. The contracted operations have a maximum maturity of 18 months.

Such operations were designed for the hedge accounting of cash flows as from January 1, 2017, and seek to hedge future dollar-denominated revenues with maturities in months coinciding with the maturity of the derivatives.

Dollar put options were recognized initially at fair value and measured subsequently at their fair value at the end of each period. Any gain or loss related to the effective portion of dollar options (intrinsic value) is recognized as other comprehensive income or loss under shareholders' equity. Any gain or loss related to the ineffective portion and the extrinsic value of the option are immediately recognized in financial results.

Considering the strong cash generation in recent quarters, the Management of the Company believed it was appropriate to advance the payment of dollar-denominated obligations, including liabilities designated for this hedge. As a result of the decision, the amount of US$402,325 was discontinued prospectively. Exchange variation on the discontinued amount, of R$495,860, which is recorded under Shareholders' Equity as “Other comprehensive income” (OCI) will be taken to net financial income (expenses) as from October 2017, as the hedged exports are realized.

15.5. Sensitivity analysis

Financial instruments, including derivatives, may be subject to changes in their fair value as a result of the variation in commodity prices, foreign exchange rates, interest rates, shares and share indexes, price indexes and other variables. The sensitivity of the derivative and non-derivative financial instruments to these variables are presented below:

(a) Selection of risks

On September 30, 2017, the main risks that can affect the value of Braskem’s financial instruments are:

· Brazilian real/U.S. dollar exchange rate;

· Brazilian real/Mexican peso exchange rate;

· Libor floating interest rate;

· Selic interest rate;

· CDI interest rate; and

· TJLP interest rate.

For the purposes of the risk sensitivity analysis, Braskem presents the exposures to currencies as if they were independent, that is, not reflecting in the exposure to a foreign exchange rate the risks of the variation in other foreign exchange rates that could be directly influenced by it.

All amounts in thousands, unless otherwise stated

(b) Value at risk

The value at risk of the derivatives held by Braskem which is defined as the loss that could result in one month as from September 30, 2017, with a probability of 5%, and under normal market conditions, was estimated by the Company at US$40,517 for the NCE exchange rate swap (Note 15.2.1(a.ii)) and at US$6,634 for put and call options (Note 15.2.1(a.i)) and US$11,151 for the swap of Libor related to Braskem Idesa’s project.

(c) Selection of scenarios

(c.1) Probable scenario

The Focus Market Readout published by the Central Bank of Brazil was used to create the probable scenario for the U.S. dollar/Brazilian real exchange rate, Selic basic interest rate and the CDI interest rate, using the reference date of September 29, 2017. According to the Market Readout, at the end of 2017, the U.S. dollar will depreciate by 0.25% against the Brazilian real, compared to the closing PTAX rate at September 29, 2017, while the Selic rate will be 7% p.a. The Selic rate is used as a reference for analyses of sensitivity to the CDI.

The probable scenario for the TJLP is a decrease of 0.5% from the current rate of 7.0%, in line with the size of the government’s most recent decisions to increase or decrease the rate. The Market Readout does not publish forecasts for the Libor interest rate. Therefore, to determine the probable scenario, Braskem considered a 5% increase on current market levels.

Notes to the unaudited condensed consolidated interim financial information

at September 30, 2017

All amounts in thousands, unless otherwise stated

(a) Civil claims

In January 2017, the Company became defendant in a civil lawsuit filed by former reseller of solvents, claiming alleged breach of a tacit distribution agreement. On September 30, 2017, the damages claimed in the lawsuit amounted to R$158 million.

Based on the opinion of external legal counsel accompanying the case, the Management believes that the lawsuit has a possible risk of loss within an eight-year period.

No judicial deposit or other form of security was made for these suits.

(b) Tax claims

(i) Income Tax (IR) and Social Contribution (CSL) – Unlimited offsetting

In March 2017, the Company received a tax deficiency notice claiming that the methodology used to offset tax losses and tax loss carryforwards at Rio Polímeros failed to observe the limit of 30% of the Taxable Profit and Social Contribution calculation base when offsetting such liabilities with Income Tax and Social Contribution liabilities in its merger into Braskem Qpar S/A, in August 2013. On September 30, 2017, the restated value of the taxes recorded amounted to R$253 million.

The Company’s external legal advisors estimate that the administrative proceedings will be concluded by 2020.

Considering that the requirement to pay the tax liability has been suspended, currently no administrative, escrow or other type of guarantee deposit has been made for this proceeding.

(ii) IR and CSL – Expenses from using goodwill

In July 2017, the Company received a tax-deficiency notice from the Brazilian Revenue Service (“RFB”) for the deduction of expenses, in the period from 2011 to 2013, arising from the use of goodwill tax offsets arising from the acquisition by OPP Produtos Petroquímicos S/A of shares issued by Companhia Petroquímica do Sul S/A (“COPESUL”), held by OPP Química S/A in 2011.

On September 30, 2017, the restated amount of taxes and tax effects from disallowances of income tax losses and social contribution tax loss carryforwards through said tax deficiency notice is R$95 million.

The Company’s external legal advisors estimate that the administrative proceeding should be concluded in 2021.

Considering that the requirement to pay the tax liability has been suspended, currently no administrative, escrow or other type of guarantee deposit has been made for this proceeding.

(c) Social security – hazardous agents

In August 2017, the Company received a deficiency notice from RFB requiring the payment of a premium for labor accident risk to fund the special retirement plan due to the alleged exposure of its workers to hazardous agents in the period from January 2013 to December 2015. The total amount under the deficiency notice, on September 30, 2017, is R$327 million.

The Company’s external legal advisors estimate that the administrative proceeding will be concluded in 2021.

19.3. Reports of irregularities and global settlement with authorities

Complete information on the reports of irregularities and on the global settlement with authorities was presented in Note 23.3 to the Company’s annual financial statements for 2016.

(a) Global Settlement with authorities

The Leniency Agreement (“Agreement”) entered into in December 2016 with the Federal Prosecution Office (“MPF”) and with U.S. and Swiss authorities (“Global Settlement”), in the approximate amount of US$957 million (approximately R$3.1 billion) was officially ratified as follows:

1. In Brazil, the Agreement was ratified by the 5 ^th Coordination and Review Chamber of the MPF on December 15, 2016, with ratification by the 13 ^th Federal Court of Curitiba on June 6, 2017.

2. The agreement with the U.S. Department of Justice (“DoJ”) was confirmed by a U.S. court ruling on January 26, 2017.

3. The agreement with the Securities and Exchange Commission (“SEC”) was confirmed on February 28, 2017.

4. The agreement with Swiss authorities did not require ratification to produce effect.

Of the aggregate amount of the Global Settlement, the Company already has paid approximately R$1.3 billion, as follows:

1. US$94,894 (R$296,591) to the DoJ, paid on February 8, 2017;

2. US$65,000 (R$206,460) to the SEC, paid on April 27, 2017;

3. CHF30,240 (R$104,307) to the Swiss Office of the Attorney General, paid on June 27, 2017;

4. R$736,445 to the MPF, paid on July 6, 2017.

The outstanding amount, of approximately R$1.7 billion, will be paid as follows:

1. CHF64,260 to the Swiss Office of the Attorney General in four annual installments of CHF16.065 due on June 30 of each year as from 2018;

2. R$1.5 billion to the MPF in six annual installments adjusted for inflation by the variation in the IPCA inflation index due on January 30 of each year as from 2018. To guarantee payment of the installments coming due, Braskem gave as collateral assets from its property, plant and equipment corresponding to one annual installment.

(b) Reimbursement for damages and other considerations

A significant portion of the total amount of R$$2.2 billion to be paid to MPF will be made available for use in reimbursing third parties for any damages caused by the wrongdoings.

Under the Agreement, the MPF undertook to coordinate actions with other authorities or government agencies with which Braskem comes to negotiate for entering into agreements involving the facts uncovered in connection with the Agreement, the public prosecution offices of states and cities in Brazil, state-owned companies and state-controlled companies for entering into similar agreements with such organizations, including for the purpose of preventing duplicate restitution with regard to the amount paid under the Agreement.

Braskem S.A.

Notes to the unaudited condensed consolidated interim financial information

at September 30, 2017

All amounts in thousands, unless otherwise stated

The Agreement does not prevent any third party from filing proceedings to seek reimbursement for any damages caused by Braskem, which could result in payments other than those provided for in the Agreement. Therefore, the Company cannot guarantee that the total amount available for reimbursement will be sufficient to fully reimburse any third parties affected by the wrongdoings, which means that the Company may be subject to the payment of damages or financial penalties other than those provided for in the Global Settlement.

With the exception of the amount cited above, in addition to other nonpecuniary obligations imposed on Braskem under the Global Settlement, the Company could suffer a substantial negative impact on its business activities, reputation, financial condition, financial instruments and operating results, or on the liquidity and price of the securities issued by the Company. Furthermore, the negative publicity resulting from the Global Settlement could have a material adverse impact on the Company’s business, including reducing the demand for its products, financial instruments and other effects that currently cannot be estimated or measured. In addition, other authorities with jurisdiction over the Company may seek to impose additional monetary sanctions or fines or commence new investigations against the Company. Finally, as a result of the Global Settlement, the Company may be barred from entering into certain agreements with governmental authorities, and may be subject to increased operating costs in connection with its obligations to improve its governance and anti-corruption practices, including the cost of required external monitorship.

It is not possible to predict the impacts on Braskem of others investigations or any decision or action taken by authorities involving its largest shareholders, namely Odebrecht S.A. and Petróleo Brasileiro S.A. – Petrobras, or any of their subsidiaries.

(d) Class action

On July 1, 2015, a putative class action lawsuit was filed against the Company and certain of its current and former officers in the United States District Court for the Southern District of New York. In the operative complaint in the action, which is titled In re Braskem Securities Litigation , the Lead Plaintiff, Boilermaker-Blacksmith National Pension Trust, alleges that the Defendants made misrepresentations or omissions that inflated the price of the Company's stock in violation of U.S. securities laws.

The Company engaged a U.S. law firm to represent it and filed motion to dismiss on July 6, 2016. On March 31, 2017, the judge rendered a decision on the motion to dismiss, granting it in part and denying it in part.

Following the decision, the Company and the Lead Plaintiff participated in a mediation which resulted in a proposed settlement of the action. On September 14, 2017, the Company and the Lead Plaintiff signed the proposed settlement agreement (“Proposed Settlement”) and submitted it to the mentioned Court for preliminary approval, which was granted on September 15, 2017. The Proposed Settlement is subject to a number of conditions including final approval by the Court.

Under the terms of the Proposed Settlement, Braskem will pay US$10 million to resolve all claims arising out of or relating to the subject matter of the Class Action of a settlement class consisting of all persons who purchased or otherwise acquired a legal or beneficial ownership interest in Braskem American Depositary Receipts (“ADRs”) between July 15, 2010 and March 11, 2015 inclusive, with the exception of any such claims belonging to purchasers who file valid and timely requests to opt out of the settlement class.

All amounts in thousands, unless otherwise stated

In accordance with accounting standard IAS 37 (Provisions, Contingent Liabilities and Contingent Assets), the Company recorded a provision in the amount of US$10 million (R$31,680) in the item “Other income (expenses), net”. On October 2, the amount involved in the class action was deposited in court.

Braskem has made no admission of any wrongdoing or liability as part of the Proposed Settlement, and entered into the Proposed Settlement solely to avoid the risk, uncertainty, and expense of further litigation.”

The Court has scheduled a Final Approval Hearing for February 21, 2018 to determine whether the Proposed Settlement should be approved.

The Company may be named as a defendant in other legal actions. Furthermore, the Company may be required, in accordance with any applicable legal and regulatory limits, to indemnify directors, officers and employees that are defendants in the securities class action and any other related actions that may arise in the future. The litigation has required significant time and dedication of the Management of the Company and is expected to continue to require such time and attention in the future.
