  • General information
    Nexa Resources S.A. ("NEXA") was incorporated on February 26, 2014 under the laws of Luxembourg as a public limited liability company (société anonyme). Its shares are publicly traded on the New York Stock Exchange ("NYSE") and the Toronto Stock Exchange ("TSX"). The Company's registered office is located at 37A, Avenue J. F. Kennedy in the city of Luxembourg in the Grand Duchy of Luxembourg.
    NEXA and its subsidiaries (the "Company") own and operate three polymetallic mines in Peru, two polymetallic mines in Brazil and is also constructing a polymetallic mine in Brazil. The Company operations are large-scale, mechanized underground and open pit mines. The Company also owns a zinc smelter in Peru and two zinc smelters in Brazil.
    The Company's majority shareholder is Votorantim S.A. ("VSA"), which holds 64.25% of its equity. VSA is a Brazilian privately-owned industrial conglomerate that holds ownership interests in metal, steel, cement and energy companies, among others.

Principal transactions for the three and nine-month periods ended September 30, 2019

  1. Karmin acquisition agreement
    On August 26, 2019 the Company entered into a definitive arrangement with, among others, Karmin Exploration Inc. ("Karmin"), in which the Company agreed to acquire Karmin for an aggregate acquisition price of USD 70,000. Karmin indirectly held the remaining 30.0% interest of Mineração Dardanelos Ltda.("Dardanelos"), owner of the Aripuanã project.
    The acquisition price contemplates (i) the acquisition of 89,945,479 common shares, representing 100% of the issued and outstanding common shares of Karmin, for an aggregate consideration of USD 69,300 paid at closing date to the shareholders of Karmin and (ii) a USD 700 loan from the Company to Karmin for general corporate purposes.
    Pursuant to the arrangement, certain assets and liabilities of Karmin unrelated to Aripuanã project, were spun-off to a new private entity, which shares were distributed to Karmin's original shareholders. The Company will not be involved in the management or operations of the new entity. After the conclusion of the spin-off, the Aripuanã project is the only significant asset of Karmin.
    On October 16, 2019, the transaction was approved by Karmin's shareholders and it was closed on October 30, 2019, when the articles of arrangement were filed and the aggregate consideration was paid. The transaction will be accounted for as a transaction with non-controlling interests, as the Company controls Dardanelos. Any difference between the transaction's aggregated acquisition price and the non-controlling interest will be recognized in equity attributable to the NEXA's shareholders.
  2. Aripuanã project developments
    During the nine-month period ended September 30, 2019, Dardanelos' equity was increased by USD 93,885. The Company fully subscribed for its portion of the equity increase in the amount of USD
    64,455. As of September 30, 2019, the Company had registered a receivable of USD 27,946 related to a commitment made by Mineração Rio Aripuanã Ltda. to subscribe for its portion of the equity increase of Dardanelos. As part of the Karmin acquisition agreement this receivable will be derecognized against the non-controlling interest at the transaction effective date.

    On February 15, 2019, the Board of Directors approved a dividend distribution to the Company's shareholders of record on March 14, 2019 in the amount of USD 0.53 cents per common share, for a total amount of USD 69,832. Dividends were paid in cash on March 28, 2019.
    The Company's subsidiary, NEXA PERU, also declared dividends in the three-month period ended March 31, 2019 in the amount of USD 200,001, including USD 32,880 to non-controlling interests and USD 2,256 to holders of investments shares (acciones de inversión). These shares give the holders the right to receive dividends but are not entitled to voting rights or the residual value of NEXA PERU's equity.
  3. Interest rate swap
    On January 2019, the Company entered into a ten-year interest rate swap in the notional amount of USD 58,233 (equivalent to BRL 226,880) to change the Brazilian inflation component ("IPC-A") of financing arrangements with BNDES to 53.04% of the Brazilian interbank rate ("CDI"). In accordance with the Company's accounting policy, the fair value adjustment of this derivative financial instrument is accounted for in "Net financial results".

  • Basis of preparation of the consolidated financial statements
    These condensed consolidated interim financial statements for the three and nine-month periods ended September 30, 2019 have been prepared in accordance with International Accounting Standard 34 Interim Financial Reporting ("IAS 34") using the accounting principles consistent with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB").
    The Company made a voluntary election to present the condensed consolidated interim statement of

cash flows for the three-month period ended September 30, 2019 and 2018.

The Company is also presenting a condensed consolidated interim statement of changes in shareholders' equity for the three-month period ended September 30, 2019 and 2018 in accordance with SEC Act Release No. 33-10532, Disclosure update and simplification.

These condensed consolidated interim financial statements do not include all disclosures required by IFRS for annual audited consolidated financial statements and accordingly should be read in conjunction with the Company's annual audited consolidated financial statements for the year ended December 31, 2018 prepared in accordance with IFRS as issued by the IASB.

These condensed consolidated interim financial statements have been prepared on the basis of, and using the accounting policies, methods of computation and presentation consistent with those applied and disclosed in the Company's annual audited consolidated financial statements for the year ended December 31, 2018, except for the adoption of new IFRS and interpretation disclosed in Note 4.

The preparation of the condensed consolidated interim financial statements in accordance with IAS 34 requires the use of certain critical accounting estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses for the period end. These critical accounting estimates represent estimates that are uncertain and changes in those estimates could materially impact the Company's condensed consolidated interim financial statements. Actual future outcomes may differ from present estimates and the Company reviews its estimates and assumptions on an ongoing basis using the most current information available. Management also exercises judgment in the process of applying the Company's accounting policies.

The critical judgments and estimates in the application of accounting principles during the nine- month period ended September 30, 2019 are the same as those disclosed in the Company's annual audited consolidated financial statements for the year ended December 31, 2018.

These condensed consolidated interim financial statements of the Company were approved by the Board of Directors on October 31, 2019.

  • Changes in accounting policies and disclosures

New and amended IFRS standards that are effective beginning on January 1, 2019

  1. IFRS 16 - "Leases"
    Main aspects introduced by the standard
    IFRS 16 was issued in January 2016 and should be applied for periods beginning after January 1, 2019. It results in certain leases being recognized on the balance sheet by lessees, as the distinction between operating and finance leases is removed. Under the new standard, an asset (the right to use the leased item) and a financial liability to pay rentals are recognized.
    Transition method
    The Company has applied IFRS 16 from its mandatory adoption date of January 1, 2019, using the simplified transition approach and did not restate comparative amounts for the periods prior to the adoption. Right-of-use assets were measured on transition at the amount of the lease liability, adjusted by any prepaid or accrued lease expense.
    12 of 29

Nexa Resources S.A.

Notes to the condensed consolidated interim financial statements At and for three and nine-month periods ended September 30, 2019 All amounts in thousands of US dollars, unless otherwise stated

______________________________________________________________________

Practical expedients applied at the adoption

In applying IFRS 16 for the first time, the Company has used the following practical expedients permitted by the standard:

  • The accounting for low value leases and leases with a remaining term of less than 12 months as at January 1, 2019;
  • The exclusion of initial direct costs from the measurement of theright-of-use asset at the date of initial application; and
  • The use of a single discount rate to a portfolio of leases with reasonably similar characteristics.

Accounting policy

The Company may lease assets in its normal course of business. Lease terms are negotiated on an individual asset basis and contractual provisions contain a wide range of different terms and conditions. The lease agreements do not impose any covenants, but leased assets may not be used as security for borrowing purposes.

Lease contracts are recognized as a liability with a corresponding right-of-use asset at the date at which the leased asset is available for use by the Company. The right-of-use asset is amortized over the shorter of the asset's useful life and the lease term on a straight-line basis.

Liabilities arising from a lease contract are initially measured on a present value basis, using the incremental borrowing rate approach. The incremental borrowing rate is determined by the Company based on equivalent financial costs that would be charged by a counterparty for a transaction with the same currency and a similar amount, term and risk of the lease contract. The finance cost charged to the income statement produces a constant periodic rate of interest over the lease term. At September 30, 2019, interest rates were between 7.47% to 11.39% for Brazil and 3.98% to 5.49% for Peru.

Impacts of adoption

The Company recognized lease liabilities and right-of-use assets in the amount of USD 41,450 and USD 41,521, respectively. Prepayments made in 2018 in the amount of USD 71 were recognized in retained earnings at January 1, 2019. Net current assets were lowered in USD 18,612 due to the presentation of a portion of the liability as a current liability. The Company also reclassified the amount of USD 2,278 from Property, plant and equipment to Right-of-use assets and USD 3,088 from Loans and financing to Lease liabilities corresponding to contracts previously classified as financial leases under IAS 17.

As a result of the adoption, income before tax decreased by USD 789 and USD 2,571 for the three- month and nine-month period ended September 30, 2019, respectively. Adjusted EBITDA, which is used to measure segment results, increased by USD 3,807 and USD 12,519 for the three-month and nine-month period ended September 30, 2019, respectively, as the operating lease payments were previously included in Adjusted EBITDA as operating costs, but the amortization of the right-of-use assets and interest on the lease liabilities are now excluded from this measure.

  1. IFRIC 23 - Uncertainty over income tax treatmentsNature of change
    The interpretation explains how to recognize, and measure current and deferred income tax assets and liabilities where there is uncertainty over a tax treatment.

Nexa Resources S.A.

______________________________________________________________________

Transaction method

The Company has applied the standard from its mandatory adoption date of January 1, 2019.

Accounting policy

Income tax provisions for uncertainties over income tax treatments are recognized when (i) there is a probable assessment that an income tax treatment will not be accepted by a taxation authority; and (ii) the Company has a present legal or constructive obligation over income tax as a result of past events. The likelihood of losses and the estimated amount of uncertainties are periodically reviewed by the Company's legal counsel.

Income tax provisions for uncertainties over income tax treatments are measured at the present value by reflecting the effect of the uncertainty in determining the related taxable profit (tax loss), tax bases, unused tax losses, unused tax credits or tax rates, through the most likely amount method.

Impacts of adoption

The interpretation affected primarily the accounting for the Company's uncertain income taxes treatments with a probable likelihood that a taxation authority will not accept such treatments. The impact of the adoption of IFRIC 23 at January 1, 2019 is USD 4,023. The Company also reclassified the amount of USD 6,047 from Provisions to Deferred income taxes.

  1. On April 25, 2019 the Luxembourg Parliament approved the 2019 Budget Law, including a reduction of the corporate income tax rate from 26.01% to 24.94%, effective for year 2019. As NEXA's tax credits on net operating losses resulting from its standalone activities do not meet the recognition criteria, no deferred tax assets are recognized. As a result, the change has no impact to the condensed consolidated interim income statement.

  1. Loans and financing are measured at amortized cost. Therefore, the amounts presented in this note do not match with the condensed consolidated interim balance sheet.

The carrying amount of other financial instruments measured at amortized cost do not differ significantly from their fair value.

  1. Fair value measurement and disclosures
    The valuation techniques used in the fair value measurement and disclosure processes, including the critical accounting estimates used and judgements made by the Company, are consistent with those applied and disclosed in the Company's annual audited consolidated financial statements for the year ended December 31, 2018.
    There were no reclassifications between fair value levels in the nine-month period ended September 30, 2019. None of the financial instruments were classified as Level 3 as of September 30, 2019.

22 Impairment loss

  • The Company performs an assessment of impairment indicators at each reporting date in accordance with notes 13 and 14 of the annual audited consolidated financial statements. For the three-month period ended September 30, 2019, the Company's assessment identified the following impairment indicators:

  • The spot average zinc LME prices declined 15.1% in comparison with thethree-month period ended June 30, 2019;
  • A reduction in the life of mine of some of our operations due to a decrease in mineral reserves and resources estimates;
  • The carrying amount of the net assets of the Company is persistently above the Company's market value.

______________________________________________________________________

The Company's management concluded that the combination of these indicators could indicate a material impact in the recoverable amount of our cash-generating units ("CGUs"). Therefore, an estimation of the recoverable amount of all the Company´s CGUs was performed as at September 30, 2019.

Below is a breakdown of the CGU's carrying amount tested for impairment as at September 30, 2019:

    1. Represents the lowest level within the Company at which the goodwill generated in the acquisition of NEXA PERU is monitored.
    2. Currently Três Marias smelter is integrated with the operations of Vazante and Morro Agudo and, therefore, are considered as a single CGU.
    3. Corresponds to the fair value of the identifiable intangible assets in the acquisition of NEXA PERU, which are recognized at the consolidated level.
  1. Key assumptions used in impairment test

  2. The recoverable amount of each CGUs was determined based on value-in-use method, which was higher than the fair value less costs to sell. This approach is consistent with the annual impairment testing disclosed in note 14 of the annual audited consolidated financial statements as at December 31, 2018.
    The Company identified long-term metal prices, pre-tax discount rate and life of mine ("LOM") as key assumptions for the recoverable amount determination, due to the material impact that such assumptions may cause on the discounted cash flow determination. These assumptions are summarized below:

  1. Impairment test analysis
    Following the determination of the recoverable amount of the CGUs, the Company compared the carrying amount of each CGU with its respective recoverable amount. At this step, the Company identified an impairment loss at the CGU Cerro Pasco (note 22(c)).
    The second step was to test whether the goodwill allocated to a CGU or a group of CGUs is recoverable. In performing this analysis, the recoverable amount of Cerro Lindo and Cerro Pasco are aggregated in a group of CGUs called Mining Peru, which represents the lowest level within the Company at which goodwill of the acquisition of NEXA PERU is monitored. This aggregated recoverable amount is compared with the aggregated carrying amount of the CGUs. No impairment loss was verified at this level.
  2. Impairment loss - Cerro Pasco
    The reduction in the mineral reserves and resources estimates that led to a shortening of the life of mine of Cerro Pasco CGU from 21 to 13 years was determinant for the recognition of an impairment loss of USD 142,133.
    As the impairment loss was identified at the CGU level and was not directly related to a single asset, the loss was allocated in a pro rata basis to the following assets:

Carrying amount

The Company performed a stress test on the key assumptions used for the calculation of the value- in-use of the CGU Cerro Pasco. A decrease of 5% in the long-term LME zinc price to USD 2,442 per ton compared to management´s estimation at September 30, 2019 would have had resulted in the recognition of an additional impairment loss of USD 73,577. Also, an increase of 5% in the pre-tax discount rate to 10.53% ton compared to management´s estimation at September 30, 2019 would have had resulted in an additional impairment loss of USD 11,428.

  1. Impairment results - Other CGUs
    The impairment indicators listed above led to a decrease in the recoverable amount of all our CGUs. However, the effects were less prominent than in the CGU Cerro Pasco and no impairment loss were identified in other CGUs.

The Company also assessed that, for some of the CGUs that were not subjected to an impairment loss, a reasonably possible change in some of the key assumptions used for cash flow determination of the CGUs, would cause the carrying amount to exceed its recoverable amount. As a result, the Company estimated the amount by which the value assigned to each of these key assumptions must change in order for the CGU recoverable amount to be equal to its carrying amount:

23 Events after the reporting period

  1. Revolving credit facility
    On October 25, 2019, the Company entered into a revolving credit facility with a syndicate of lenders, which allows the Company to borrow up to USD 300,000. The revolving credit facility is to be used for general corporate purposes and provides the Company with increased liquidity and additional flexibility. The revolving credit facility has a term of five years and the amounts drawn are subject to an interest rate of 1.0% + LIBOR 3M. The transaction costs will be capitalized and amortized over the contractual term.
  2. Export credit note
    On October 23, 2019, in order to expand short-term liquidity in Brazil, the Company entered into an Export Credit Note agreement in the principal amount of USD 90,000 and cost of Libor 3M + 1.5% p.a., with maturity of 5 years. Simultaneously, the Company contracted a swap to exchange the interest index to CDI rate + 1.30% p.a., as well as the currency of debt service repayments from USD to BRL. The Company will account for the Export Credit Note under the fair value option to eliminate the accounting mismatch that would arise if amortized cost were used.
  3. Vazante equipment failure
    During a regular inspection activity on October 25, 2019, a crack was identified in one of the components of the concentration plant of Vazante. Equipment repair should last approximately 30 days and during this period the mine should operate at 30% of its nominal production capacity. As a result, the Company expects a decrease in 2019 production of 8 to 10 thousand tons of zinc in concentrate. No work accidents nor environmental impacts from this failure were reported. The Company could not estimate the cost of the repairs needed as of the approval date of the condensed consolidated interim financial statements.
