Notes to the Consolidated Condensed Interim Financial Statements

1.    GENERAL INFORMATION AND BASIS OF PRESENTATION

a)  General information and basis of presentation

Ternium S.A. (the “Company” or “Ternium”), was incorporated on December 22, 2003 to hold investments in flat and long steel manufacturing and distributing companies.  The Company has an authorized share capital of a single class of 3.5 billion shares having a nominal value of USD 1.00 per share.  As of March 31, 2017, there were 2,004,743,442 shares issued.  All issued shares are fully paid.

Following a corporate reorganization carried out during fiscal year 2005, in January 2006 the Company successfully completed its registration process with the United States Securities and Exchange Commission (“SEC”).  Ternium’s ADSs began trading on the New York Stock Exchange under the symbol “TX” on February 1, 2006.  The Company’s initial public offering was settled on February 6, 2006.  

The Company was initially established as a public limited liability company (société anonyme) under Luxembourg’s 1929 holding company regime.  Until termination of such regime on December 31, 2010, holding companies incorporated under the 1929 regime (including the Company) were exempt from Luxembourg corporate and withholding tax over dividends distributed to shareholders.

On January 1, 2011, the Company became an ordinary public limited liability company (société anonyme) and, effective as from that date, the Company is subject to all applicable Luxembourg taxes (including, among others, corporate income tax on its worldwide income) and its dividend distributions will generally be subject to Luxembourg withholding tax. However, dividends received by the Company from subsidiaries in high income tax jurisdictions, as defined under Luxembourg law, will continue to be exempt from corporate income tax in Luxembourg under Luxembourg’s participation exemption.

As part of the Company’s corporate reorganization in connection with the termination of Luxembourg’s 1929 holding company regime, on December 6, 2010, the Company contributed its equity holdings in all its subsidiaries and all its financial assets to its Luxembourg wholly-owned subsidiary Ternium Investments S.à r.l., or Ternium Investments, in exchange for newly issued corporate units of Ternium Investments. As the assets contributed were recorded at their historical carrying amount in accordance with Luxembourg GAAP, the Company’s December 2010 contribution of such assets to Ternium Investments resulted in a non-taxable revaluation of the accounting value of the Company’s assets under Luxembourg GAAP. The amount of the December 2010 revaluation was equal to the difference between the historical carrying amounts of the assets contributed and the value at which such assets were contributed and amounted to USD 4.0 billion. However, for the purpose of these consolidated condensed interim financial statements, the assets contributed by Ternium to its wholly-owned subsidiary Ternium Investments were recorded based on their historical carrying amounts in accordance with IFRS, with no impact on the financial statements.

1.    GENERAL INFORMATION AND BASIS OF PRESENTATION (continued)

Following the completion of the corporate reorganization, and upon its conversion into an ordinary Luxembourg holding company, the Company voluntarily recorded a special reserve exclusively for tax-basis purposes. As of December 31, 2016 and 2015, this special reserve amounted to USD 6.9 billion and USD 7.1 billion, respectively. The Company expects that, as a result of its corporate reorganization, its current overall tax burden will not increase, as all or substantially all of its dividend income will come from high income tax jurisdictions. In addition, the Company expects that dividend distributions for the foreseeable future will be imputed to the special reserve and therefore should be exempt from Luxembourg withholding tax under current Luxembourg law.

The name and percentage of ownership of subsidiaries that have been included in consolidation in these Consolidated Condensed Interim Financial Statements is disclosed in Note 2 to the audited Consolidated Financial Statements for the year ended December 31, 2016.

Certain comparative amounts have been reclassified to conform to changes in presentation in the current period. These reclassifications do not have a material effect on the Company’s condensed interim consolidated financial statements.

The preparation of Consolidated Condensed Interim Financial Statements requires management to make estimates and assumptions that might affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the statement of financial position, and also the reported amounts of revenues and expenses for the reported periods. Actual results may differ from these estimates. The main assumptions and estimates were disclosed in the Consolidated Financial Statements for the year ended December 31, 2016, without significant changes since its publication.

Material intercompany transactions and balances have been eliminated in consolidation. However, the fact that the functional currency of the Company’s subsidiaries differs, results in the generation of foreign exchange gains and losses that are included in the Consolidated Condensed Interim Income Statement under “Other financial income (expenses), net”.

These Consolidated Condensed Interim Financial Statements have been approved for issue by the Board of Directors of Ternium on April 25, 2017.

2.     ACCOUNTING POLICIES

These Consolidated Condensed Interim Financial Statements have been prepared in accordance with IAS 34, “Interim Financial Reporting” and are unaudited. These Consolidated Condensed Interim Financial Statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2016, which have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and in conformity with International Financial Reporting Standards as adopted by the European Union (“EU”). Recently issued accounting pronouncements were applied by the Company as from their respective dates.

2.     ACCOUNTING POLICIES (continued)

These Consolidated Condensed Interim Financial Statements have been prepared following the same accounting policies used in the preparation of the audited Consolidated Financial Statements for the year ended December 31, 2016. Given that the Company has entered into a new leasing agreement that qualifies as finance leasing (see note 10), and the related accounting policy was not disclosed in the Consolidated Financial Statements as of December 31, 2016, as the Company did not have any financial leasing at such date, the accounting policy is detailed below:

Finance leases

Leases of property, plant and equipment where the Company, as lessee, has substantially all the risks and rewards of ownership are classified as finance leases. Finance leases are capitalized at the lease’s inception at the fair value of the leased property or, if lower, the present value of the minimum lease payments. The corresponding rental obligations, net of finance charges, are included in other short-term and long-term payables. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to the profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant and equipment acquired under finance leases is depreciated over the asset’s useful life or over the shorter of the asset’s useful life and the lease term if there is no reasonable certainty that the Company will obtain ownership at the end of the lease term.

None of the accounting pronouncements issued after December 31, 2016, and as of the date of these Consolidated Condensed Interim Financial Statements have a material effect on the Company’s financial condition or result or operations.

3.    SEGMENT INFORMATION

REPORTABLE OPERATING SEGMENTS

The Company is organized in two reportable segments: Steel and Mining.

The Steel segment includes the sales of steel products, which comprises slabs, hot rolled coils and sheets, cold rolled coils and sheets, tin plate, welded pipes, hot dipped galvanized and electro-galvanized sheets, pre-painted sheets, billets (steel in its basic, semi-finished state), wire rod and bars and other tailor-made products to serve its customers’ requirements.

The Steel segment comprises three operating segments: Mexico, Southern Region and Other markets. These three segments have been aggregated considering the economic characteristics and financial effects of each business activity in which the entity engages; the related economic environment in which it operates; the type or class of customer for the products; the nature of the products; and the production processes. The Mexico operating segment comprises the Company’s businesses in Mexico. The Southern region operating segment manages the businesses in Argentina, Paraguay, Chile, Bolivia and Uruguay. The Other markets operating segment includes businesses mainly in United States, Colombia, Guatemala, Costa Rica, El Salvador, Nicaragua and Honduras.

The Mining segment includes the sales of mining products, mainly iron ore and pellets, and comprises the mining activities of Las Encinas, an iron ore mining company in which Ternium holds a 100% equity interest and the 50% of the operations and results performed by Peña Colorada, another iron ore mining company in which Ternium maintains that same percentage over its equity interest. Both mining operations are located in Mexico.

3.    SEGMENT INFORMATION (continued)

Ternium’s Chief Operating Decision Maker (CEO) holds monthly meetings with senior management, in which operating and financial performance information is reviewed, including financial information that differs from IFRS principally as follows:

- The use of direct cost methodology to calculate the inventories, while under IFRS is at full cost, including absorption of production overheads and depreciation.

- The use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at historical cost (with the FIFO method).

- Other timing and non-significant differences.

Most information on segment assets is not disclosed as it is not reviewed by the CODM (CEO).

3.      SEGMENT INFORMATION (continued)

GEOGRAPHICAL INFORMATION

There are no revenues from external customers attributable to the Company’s country of incorporation (Luxembourg).

For purposes of reporting geographical information, net sales are allocated based on the customer’s location. Allocation of non-current assets is based on the geographical location of the underlying assets.

(1) It includes the investments held in Techgen S.A. de C.V., Finma S.A.I.F., Arhsa S.A., Techinst S.A., Recrotek  S.R.L. de C.V. and Gas Industrial de Monterrey S.A. de C.V.

(a) Usinas Siderurgicas de Minas Gerais S.A. - USIMINAS

On January 16, 2012, the Company’s wholly-owned Luxembourg subsidiary Ternium Investments S.à r.l. (“Ternium Investments”), together with the Company’s Argentine majority-owned subsidiary Siderar S.A.I.C. (“Siderar”), Siderar’s wholly-owned Uruguayan subsidiary Prosid Investments S.A. (“Prosid”), and Confab Industrial S.A., a Brazilian subsidiary of Tenaris S.A. (“TenarisConfab”), joined Usiminas’ existing control group through the acquisition of 84.7, 30.0, and 25.0 million ordinary shares, respectively. The rights and obligations of the control group members are governed by a shareholders’ agreement. As a result of these transactions, the control group, which holds ordinary shares representing the majority of Usiminas’ voting rights, is formed as follows: Nippon Steel & Sumitomo Metal Corporation Group (“NSSMC”, formerly Nippon Group), with 46.1% of the voting rights within the control group; T/T Group (comprising TenarisConfab, Prosid, Siderar and Ternium Investments), with 43.3%; and Previdência Usiminas (Usiminas’ employee pension fund), with the remainder 10.6%.

On October 2, 2014, Ternium Investments entered into a purchase agreement with Caixa de Previdência dos Funcionários do Banco do Brasil – PREVI for the acquisition of 51.4 million ordinary shares of Usiminas at a price of BRL 12 per share, for a total amount of BRL 616.7 million. On October 30, 2014, Ternium Investments completed the acquisition. These additional shares are not subject to the Usiminas shareholders agreement, but must be voted in accordance with the control group decisions.

On April 20, 2016, Ternium (through Ternium Investments, Siderar and Prosid) subscribed, in the aggregate, to 8.5 million preferred shares for a total subscription price of BRL 10.9 million (approximately USD 3.1 million). These preferred shares were issued on June 3, 2016. 

9.       INVESTMENTS IN NON-CONSOLIDATED COMPANIES (continued)

On April 18, 2016, Usiminas’ extraordinary general shareholders’ meeting approved an issuance of 200 million ordinary shares for an aggregate amount of BRL 1 billion and Usiminas launched a multi-round subscription process. On July 19, 2016, following the completion of the subscription process, Usiminas’ extraordinary general shareholders’ meeting homologated the capital increase, and Ternium (through Ternium Investments, Siderar and Prosid) was issued, in the aggregate, 76.4 million ordinary shares for a total subscription price of BRL 382.2 million (approximately USD 110.9 million). Following the issuance of these ordinary shares, Ternium (through Ternium Investments, Siderar and Prosid) owns a total of 242.6 million ordinary shares and 8.5 million preferred shares, representing 20.5% of Usiminas’ capital, and the T/T Group owns 39.6% of Usiminas’ ordinary shares and 1.8% of Usiminas’ preferred shares. Ternium continues to hold 35.6% of Usiminas’ voting rights within the control group and has a participation in Usiminas’ results of 20.5%.

As of March 31, 2017, the closing price of the Usiminas ordinary and preferred shares, as quoted on the BM&F Bovespa Stock Exchange, was BRL 8,38 (approximately USD 2,64) per ordinary share and BRL 4,44 (approximately USD 1,40) per preferred share, respectively. Accordingly, as of March 31, 2017, Ternium’s ownership stake had a market value of approximately USD 653.5 million and a carrying value of USD 447.4 million.

The Company reviews periodically the recoverability of its investment in Usiminas. To determine the recoverable value, the Company estimates the value in use of the investment by calculating the present value of the expected cash flows or its fair value less costs of disposal.

Management expects that Usiminas financial restructuring process (that started in April 2016 with the capital increase) will be completed in the next months. The completion of this process together with the improvement in the share price since June 2016 may lead to an improvement in the value of the investment in Usiminas in future periods.

As of March 31, 2017, the value of the investment in Usiminas is comprised as follows:

The investment in Usiminas is based in the following calculation:

9.    INVESTMENTS IN NON-CONSOLIDATED COMPANIES (continued)

On April 19, 2017, Usiminas approved its consolidated interim accounts as of and for the three-month period ended March 31, 2017, which state that revenues, net profit from continuing operations and shareholders’ equity amounted to USD 747 million, USD 34 million and USD 4,331 million, respectively.

10.  FINANCE LEASES

As of March 31, 2017, the Company has a contract that qualifies as financial lease agreement with Air Liquide Argentina S.A., being the object of the lease a plant for the provision of industrial gas located in the Company’s plant in San Nicolas, Argentina. This contract does not consider a purchase option of the related asset on its expiry date. The total commitment generated a current finance lease liability of USD 7.7 million and a non-current finance lease liability of USD 67.2 million. The total finance lease liability to be paid on expiry of the lease contract amounts to USD 74.9 million.

The reconciliation of the minimum future payments and the present value of the contract are as follows:

Property, plant and equipment include a net book value of USD 76.0 million in connection with assets leased to the Company under this finance lease. The duration of the lease contract is 15 years and the amortization period of the related asset is 15 years as well.

11.  DISTRIBUTION OF DIVIDENDS

On February 21, 2017, the Board of Directors proposed a dividend distribution of USD 0.10 per share (USD 1.00 per ADS), or approximately USD 196.3 million in the aggregate, which is subject to shareholders’ approval at the Company’s annual general shareholders’ meeting to be held on May 3, 2017. If the annual dividend is approved at the shareholders’ meeting, it will be paid on May 12, 2017, with record-date of May 9, 2017.

12.  CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS

This note should be read in conjunction with Note 24 to the Company’s audited Consolidated Financial Statements for the year ended December 31, 2016. The main contingencies and commitments are as follows:

(i) Tax claims and other contingencies

(a) Companhia Siderúrgica Nacional (CSN) – Tender offer litigation

Following a January 2012 acquisition of a significant participation in Usinas Siderúrgicas de Minas Gerais S.A. – USIMINAS (Usiminas) by Ternium Investments S.à r.l. (Ternium Investments), its subsidiary Siderar, and Confab Industrial S.A. --a Brazilian subsidiary of Tenaris S.A.--, Companhia Siderúrgica Nacional (CSN) and various entities affiliated with CSN initiated a lawsuit against the acquirers. The CSN lawsuit alleges that, under applicable Brazilian laws and rules, the acquirers were required to launch a tag-along tender offer to all non-controlling holders of Usiminas ordinary shares for a price per share equal to 80% of the price per share paid in such acquisition, or BRL 28.8, and seeks an order to compel the acquirers to launch an offer at that price plus interest. If so ordered, the offer would need to be made to 182,609,851 ordinary shares of Usiminas not belonging to Usiminas’ control group; Ternium Investments and Siderar’s respective shares in the offer would be of 60.6% and 21.5%. On September 23, 2013, the first instance court dismissed the CSN lawsuit, and on February 8, 2017, the court of appeals maintained the understanding of the first instance court. CSN has already filed a motion for clarification against the decision of the court of appeals, and may still appeal to the Superior Court of Justice or the Federal Supreme Court. For further information on the CSN lawsuit, see note 24 to Ternium’s Consolidated Financial Statement for the year ended December 31, 2016.

Ternium continues to believe that all of CSN's claims and allegations are groundless and without merit, as confirmed by several opinions of Brazilian legal counsel, two decisions issued by the Brazilian securities regulator (the Comissão de Valores Mobiliários, or CVM) in February 2012 and December 2016 in connection with the acquisition, and the first and second instance court decisions referred to above. Accordingly, no provision was recorded in these Consolidated Condensed Interim Financial Statements.

(b) Shareholder claims relating to the October 2014 acquisition of Usiminas shares

On April 14, 2015, the staff of the CVM determined that a second acquisition of ordinary shares of Usiminas by Ternium Investments, completed in October 2014, triggered a requirement under applicable Brazilian laws and regulations for Usiminas’ controlling shareholders to launch a tender offer to all non-controlling holders of Usiminas ordinary shares. The CVM staff’s determination was made further to a request by Nippon Steel & Sumitomo Metal Corporation (NSSMC) and its affiliates, who alleged that Ternium’s 2014 acquisition had exceeded a threshold that triggers the tender offer requirement. In the CVM staff’s view, the 2014 acquisition exceeded the applicable threshold by 5.2 million shares. On April 29, 2015, Ternium filed an appeal to be submitted to the CVM’s Board of Commissioners. On May 5, 2015, the CVM staff confirmed that the appeal would be submitted to the Board of Commissioners and that the effects of the staff’s decision would be stayed until such Board rules on the matter. On June 15, 2015, upon an appeal filed by NSSMC, the CVM staff changed its earlier decision and stated that the obligation to launch a tender offer would fall exclusively on Ternium. Ternium’s appeal has been submitted to the CVM’s Board of Commissioners and it is currently expected that such Board will rule on the appeal in the first half of 2017. In the event the appeal is not successful, under applicable CVM rules Ternium may elect to sell to third parties the 5.2 million shares allegedly acquired in excess of the threshold, in which case no tender offer would be required.

12.  CONTINGENCIES, COMMITMENTS AND RESTRICTIONS ON THE DISTRIBUTION OF PROFITS (continued)

(c) Potential Mexican income tax adjustment

In March 2015, the Mexican tax authorities, as part of a tax audit to Ternium Mexico with respect to fiscal year 2008, challenged the deduction by Ternium Mexico’s predecessor IMSA Acero of a tax loss arising from an intercompany sale of shares in December 2008. Although the tax authorities have not yet determined the amount of their claim, they have indicated in a preliminary report that they have observations that may result in an income tax adjustment currently estimated at approximately USD 59 million, including interest and fines.

Ternium Mexico requested an injunction from the Mexican courts against the audit observations, and also filed its defense and supporting documents with the Mexican tax authorities. The Company, based on the advice of counsel, believes that an unfavorable outcome in connection with this matter is not probable and, accordingly, no provision has been recorded in its financial statements.
