Notes to the Financial Statements

1.      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 September 30, 2013, 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.  On January 31, 2011, the Company filed with the SEC a registration statement on form F-3 relating to sales of equity and debt securities.

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 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, 2012 and 2011, this special tax reserve amounted to USD 7.6 billion and USD 7.7 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, 2012.

Certain comparative amounts have been reclassified to conform to changes in presentation in the current period, and also to reflect the changes necessary for September 30, 2012 in connection with the completion of the purchase price allocation of Usiminas.

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.

Material intercompany transactions and balances have been eliminated in consolidation. However, the fact that the functional currency of the Company’s subsidiaries differ, 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 November 5, 2013.

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, 2012, which have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board, and adopted by the European Union. Recently issued accounting pronouncements were applied by the Company as from their respective dates.

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, 2012, except for the changes described in note 3.

In September 2013, Argentina enacted a law that amends its income tax law. The law includes a new 10% withholding tax on dividend distributions made by Argentine companies to foreign beneficiaries. Accordingly, as of September 30, 2013, the Company recorded an income tax provision of USD 24.0 million, for the deferred tax liability on reserves for future dividends at our Argentine subsidiaries.

3.      NEW OR AMENDED ACCOUNTING STANDARDS ADOPTED

The Company has applied the following standards as of January 1, 2013:

•    IAS 19, “Employee benefits”

In June 2011, the IASB issued IAS 19 (amended 2011), “Employee benefits”, which makes significant changes to the recognition and measurement of defined benefit pension expense and termination benefits, and to the disclosures for all employee benefits.

As a consequence of this application of this standard, the following note should replace note 4 (n)(1) paragraphs 1 to 5 as included in the audited Consolidated Financial Statements for the year ended December 31, 2012:

(1) Pension obligations and other post-employment obligations

The Company has defined benefit and defined contribution plans. A defined benefit plan is a pension plan that defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.

The liability recognized in the statement of financial position 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 (at year end) by independent actuaries using the projected unit credit method.

Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise.

 Past-service costs are recognized immediately in income.

For defined benefit plans, net interest income/expense is calculated based on the surplus or deficit derived by the difference between the defined benefit obligations less plan assets.

The effect of these adjustments in the pension obligations and other post-employment obligations is as follows:

3.      NEW OR AMENDED ACCOUNTING STANDARDS ADOPTED (continued)

•    Amendments to IAS 1, “Financial statement presentation”

In June 2011, the IASB issued IAS 1 (amended 2011), “Financial statement presentation”. The amendment requires entities to separate items presented in Other comprehensive income into two groups, based on whether or not they may be recycled to profit or loss in the future. See impact of the application in the Consolidated Condensed Interim Statements of Comprehensive Income.

•    IFRS 13, “Fair value measurement”

In May 2011, the IASB issued IFRS 13, “Fair value measurement”. The standard explains how to measure fair value and aims to enhance fair value disclosures. See information related to this standard in note 14.

4.      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. Starting on January 1, 2013, it also includes 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. In the comparative information as of September 30, 2012, the 50% of the operations and results performed by Peña Colorada are only included under management view, see explanation included in note 10.

4.      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).

- Under IFRS, the results of Peña Colorada are aggregated in equity in earnings of non-consolidated companies until December 31, 2012. Starting on January 1, 2013, these results are included considering 50% of the operations on a line by line basis, see note 10 for further detail. In the comparative information as of September 30, 2012, the 50% of the operations and results performed by Peña Colorada are only included under management view.

- Other timing and non-significant differences.

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

GEOGRAPHICAL INFORMATION

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

(2)   Formerly Lomond Holdings B.V. Until December 31, 2012, Ternium’s investment in Exiros B.V. was presented as an investment in non-consolidated companies and its results under the equity in earnings (losses) in non-consolidated companies within the consolidated income statement.

(3) It includes the investment held in 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.

(and Siderar’s wholly-owned Uruguayan subsidiary Prosid Investments S.C.A.), 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. As a result of these transactions, the control group, which holds 329.4 million ordinary shares representing the majority of Usiminas’ voting rights, is now formed as follows: Nippon Group 47.2%, Ternium/Tenaris Group 42.4%, and CEU 10.4%.

On October 29,  2013,  Usiminas approved its interim accounts as of and for the nine-months ended September 30, 2013, which state that revenues, post-tax losses from continuing operations and shareholders’ equity  amounted to USD 4,566 million, USD 75 million and USD 7,444 million, respectively.

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

This note should be read in conjunction with Note 25 to the Company’s audited Consolidated Financial Statements for the year ended December 31, 2012.  Significant changes or events since the date of issue of such financial statements are as follows:

(i) Siderar.  AFIP – Income tax claim for fiscal years 1995 to 1999

The Administración Federal de Ingresos Públicos (“AFIP” – the Argentine tax authority) has challenged the charge to income of certain disbursements that Siderar has treated as expenses necessary to maintain industrial installations, which as such should be deducted in the year in which they take place.  The AFIP asserts that these are investments or improvements that must be capitalized and, therefore, it made a jeopardy assessment of income tax due on a nominal tax basis plus fines and interest in fiscal years 1995 to 1999 amounting to approximately USD 15.5 million as of September 30, 2013.
