References in this annual report to “pesos” or “Ps.” are to the lawful currency of Mexico. References to “tons” in this annual report refer to tons; a metric ton equals 1,000 kilograms or 2,204 pounds. We publish our financial statements in pesos.

The terms “special bar quality steel” or “SBQ steel” refer to steel that is hot rolled or cold finished into round square, or hexagonal steel bars that generally contain higher proportions of alloys than lower quality grades of steel. SBQ steel is produced with precise chemical specifications and generally is made to order following client specifications.

This annual report contains translations of certain peso amounts to U.S. dollars at specified rates solely for your convenience. These translations do not mean that the peso amounts actually represent such dollar amounts or could be converted into U.S. dollars at the rate indicated. Unless otherwise indicated, we have translated these U.S. dollar amounts from pesos at the exchange rate of Ps. 19.6566 per U.S.$1.00, the interbank transactions rate in effect on December 31, 2018. On July 30, 2019, the interbank transactions rate for the peso was Ps. 19.0900 per U.S.$1.00.

FORWARD LOOKING STATEMENTS

This annual report contains certain statements regarding our business that may constitute “forward looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. When used in this annual report, the words “anticipates,” “plans,” “believes,” “estimates,” “intends,” “expects,” “projects” and similar expressions are intended to identify forward looking statements, although not all forward looking statements contain those words. These statements, including, but not limited to, our statements regarding our strategy for raw material acquisition, products and markets, production processes and facilities, sales and distribution and exports, growth and other trends in the steel industry and various markets, operations and liquidity and capital resources, are based on management’s beliefs, as well as on assumptions made by, and information currently available to, management, and involve various risks and uncertainties, some of which are beyond our control. Our actual results could differ materially from those expressed in any forward looking statement. In light of these risks and uncertainties, we cannot assure you that forward looking statements will prove to be accurate. Factors that might cause actual results to differ materially from forward looking statements include, but are not limited to, the following:

● factors relating to the steel industry (including the cyclicality of the industry, finished product prices, worldwide production capacity, the high degree of competition from Mexican, U.S. and foreign producers and the price of ferrous scrap, iron ore and other raw materials);

● our inability to operate at high capacity levels;

● the costs of compliance with Mexican and U.S. environmental laws;

● future capital expenditures and acquisitions;

● future devaluations of the peso;

● the imposition by Mexico of foreign exchange controls and price controls;

● the influence of economic and market conditions in other countries on Mexican securities; and

● the factors discussed in Item 3.D – “Risk Factors” below.

Forward looking statements speak only as of the date they were made, and we undertake no obligation to update publicly or to revise any forward looking statements after the date of this annual report because of new information, future events or other factors. In light of the risks and uncertainties described above, the forward looking events and circumstances discussed in this annual report might not occur.

PART I

Item 1. Identity of Directors, Senior Management and Advisers

Not applicable.

Item 2. Offer Statistics and Expected Timetable

Not applicable.

Item 3. Key Information

A. Selected Financial Data

This annual report includes our consolidated financial statements as of December 31, 2017 and 2018 and for each of the three years ended December 31, 2016, 2017 and 2018, as adopted by the International Financial Reporting Standards Board (IFRS), and its amendments and interpretations, as issued by the International Accounting Standard Board (IASB). We have adjusted the financial statements of our subsidiaries to conform to IFRS, and we have translated them to Mexican pesos. See Note 4 to our consolidated financial statements included elsewhere herein.

When preparing the financial statements for our individual subsidiaries and transactions in currencies other than our functional currency, the first step to convert financial information from operations abroad is the determination of the functional currency. The functional currency is the currency of the primary economic environment of the foreign operation or, if different, the currency that mainly impacts its cash flows. The U.S. dollar was considered as the functional currency of all the U.S. subsidiaries and the Brazilian Real was considered as the functional currency for all the Brazil plants; therefore, the financial statements of these subsidiaries were translated into Mexican pesos by applying:

- The exchange rates at the balance sheet date, to all assets and liabilities.

- The historical exchange rate at stockholders’ equity accounts and revenues, costs and expenses.

Translation differences are carried directly to the consolidated statements of comprehensive income as other comprehensive income under the caption “translation effects of foreign subsidiaries.” Translation differences were carried directly to the consolidated statement of comprehensive income as part of the income of the year under the caption foreign exchange gain (loss).

The translation effect in the results of operations for the years ended December 31, 2018, 2017 and 2016 resulted from applying the following exchange rates (peso/dollar) to the active or passive monetary position in foreign currency:

Year ended	Exchange Rate (pesos to US$1.00)	Change
December 31, 2016	20.6640	3.3242
December 31, 2017	19.7354	(0.9286)

(1) Peso amounts have been translated into U.S. dollars solely for the convenience of the reader, at the exchange rate of Ps. 19.6566 per U.S.$1.00, the interbank transactions rate in effect on December 31, 2018.

(2) Our series B shares are listed on the Mexican Stock Exchange, and the ADSs are listed on the New York Stock Exchange. One American depositary share, or “ADS,” represents three series B shares.

(3) Total long-term liabilities include amounts relating to deferred taxes.

(4) Adjusted EBITDA is not a financial measure computed under U.S. GAAP or IFRS. Adjusted EBITDA is derived from our IFRS financial information and means net income (loss) excluding: (i) depreciation, amortization and impairment expense; (ii) financial income (expense), net (which is composed of net interest expense and foreign exchange gain or loss); (iii) other income (expense); and (iv) income tax expense and employee statutory profit-sharing expense.

Adjusted EBITDA does not represent, and should not be considered as, an alternative to net income, as an indicator of our operating performance, or as an alternative to cash flow as an indicator of liquidity. You should bear in mind that Adjusted EBITDA is not defined and is not a recognized financial measure under MFRS, U.S. GAAP or IFRS and that it may be calculated differently by different companies and must be read in conjunction with the explanations that accompany it. Adjusted EBITDA as presented in this table does not take into account our working capital requirements, debt service requirements and other commitments.

We believe that Adjusted EBITDA can be useful to facilitate comparisons of operating performance between periods and with other companies in our industry because it excludes the effect of: (i) depreciation, amortization and impairment loss which represents a non-cash charge to earnings; (ii) certain financing costs, which are significantly affected by external factors, including interest rates and foreign currency exchange rates, which can have little bearing on our operating performance; (iii) other income (expense) that are non-recurring operations; and (iv) income tax expense and employee statutory profit-sharing expense. However, Adjusted EBITDA has certain significant limitations, including that it does not include the following:

● taxes, which are a necessary and recurring part of our operations;

● depreciation, amortization and impairment loss which, because we must utilize property, equipment and other assets in order to generate revenues in our operations, is a necessary and recurring part of our costs;

● comprehensive cost of financing, which reflects our cost of capital structure and assisted us in generating revenues; and

3 

● other income and expenses that are part of our net income.

Adjusted EBITDA should not be considered in isolation or as a substitute for net income, net cash flow from operating activities or net cash flow from investing and financing activities. Reconciliation of net income (loss) to Adjusted EBITDA is as follows:

(6) Installed capacity is determined at December 31 of the relevant year.

(7) Data in pesos and U.S. dollars, respectively, not in millions.

Exchange Rates

The following table sets forth, for the periods indicated, the high, low, average and period-end free-market exchange rate expressed in Mexican pesos per U.S. dollar. The average annual rates presented in the following table were calculated by using the average of the exchange rates on the last day of each month during the relevant period. The data provided in this table is based on noon buying rates published by the U.S. Federal Reserve Board for cable transfers in Mexican pesos. We have not restated the rates in constant currency units. All amounts are stated in pesos. We make no representation that the Mexican peso amounts referred to in this annual report could have been or could be converted into U.S. dollars at any particular rate or at all.

(1) Average of month-end or daily rates, as applicable.

Except for the period from September through December 1982, during a liquidity crisis, the Mexican Central Bank has consistently made foreign currency available to Mexican private-sector entities (such as us) to meet their foreign currency obligations. Nevertheless, in the event of renewed shortages of foreign currency, we cannot assure you that foreign currency would continue to be available to private-sector companies or that foreign currency needed by us to service foreign currency obligations or to import goods could be purchased in the open market without substantial additional cost or at all.

Fluctuations in the exchange rate between the peso and the U.S. dollar will affect the U.S. dollar value of securities traded on the Mexican Stock Exchange, including our series B shares and, as a result, will likely affect the market price on the New York Stock Exchange of the ADSs that represent the series B shares. Such fluctuations will also affect the U.S. dollar conversion by the depositary of any cash dividends paid in pesos on series B shares represented by ADSs.

B.	Capitalization and Indebtedness
	Not applicable.
C.	Reasons for the Offer and Use of Proceeds
	Not applicable.
D.	Risk Factors

Investing in our series B shares and the ADSs involves a high degree of risk. You should consider carefully the following risks, as well as all the other information presented in this annual report, before making an investment decision. Any of the following risks, if they were to occur, could materially and adversely affect our business, results of operations, prospects and financial condition. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also materially and adversely affect our business, results of operations, prospects and financial condition. In either event, the market price of our series B shares and ADSs could decline significantly, and you could lose all or substantially all of your investment.

Risks Related to Our Business

Our results of operations are significantly influenced by the cyclical nature of the steel industry.

The steel industry is highly cyclical and sensitive to regional and global macroeconomic conditions. Global demand for steel as well as global production capacity levels significantly influence prices for our products, and changes in global demand or supply for steel in the future will likely impact our results of operations. The steel industry has suffered in the past, especially during downturn cycles, from substantial over-capacity. Currently, as a result of the increase in steel production capacity in recent years, there are signs of excess capacity in steel markets, which is impacting the profitability of the steel industry. Global steel prices decreased in 2013, 2014 and 2015, and in 2016, 2017 and 2018 global steel prices began to recover. We cannot give you any assurance as to prices of steel in the future.

We may not be able to pass along price increases for raw materials to our customers to compensate for fluctuations in price and supply.

Prices for raw materials necessary for production of our steel products have fluctuated significantly in the past and may do so in the future. Significant increases in raw material prices could adversely affect our gross profit. During periods when prices for scrap metal, iron ore, ferroalloys, coaking coal and other raw materials have increased, our industry has historically sought to maintain profit margins by passing along increased raw material costs to customers by means of price increases. For example, prices of scrap metal in 2014 increased approximately 7%, in 2015 decreased approximately 16%, in 2016 increased approximately 2%, in 2017 increased approximately 31% and in 2018 increased approximately 19%; prices of ferroalloys in 2014 increased approximately 16%, in 2015 decreased approximately 9%, in 2016 decreased approximately 13%, in 2017 increased approximately 22% and in 2018 increased approximately 10%. We may not be able to pass along these and other cost increases in the future and, therefore, our profitability may be materially and adversely affected. Even when we can successfully increase our prices, interim reductions in profit margins frequently occur due to a time lag between the increase in raw material prices and the market acceptance of higher selling prices for finished steel products. We cannot assure you that our customers will agree to pay increased prices for our steel products that compensate us for increases in our raw material costs.

We purchase our raw materials either in the open market or from certain key suppliers. Both scrap metal and ferroalloy prices are negotiated on a monthly basis with our suppliers and are subject to market conditions. We cannot assure you that we will be able to continue to find suppliers of these raw materials in the open market, that the prices of these materials will not increase or that the quality will remain the same. In addition, if any of our key suppliers fails to deliver or we fail to renew our supply contracts, we could face limited access to some raw materials, or higher costs and delays resulting from the need to obtain our raw materials requirements from other suppliers.

The inability to use our existing inventory in the future or impairments in the valuation of our inventory could adversely affect our business.

As of December 31, 2018, we had 136,541 metric tons of coaking coal inventory, which is one of the principal raw materials used in blast furnaces. We have not used this raw material in recent years because our Lorain, Ohio blast furnace facility has been idle since 2008. We intend to start using coaking coal as a substitute for coal in our productive process in our other plants in Mexico and the United States. However we cannot assure you that we will be able to effectively utilize such inventory.

6 

We have assigned a fair market value of Ps. 953 million (U.S.$48.5 million) to our coaking coal inventory. However, prices for coaking coal have fluctuated significantly in the past and could continue to do so in the future and significant fluctuations in coaking coal prices could adversely affect the value of our existing inventory.

The energy costs involved in our production processes are subject to fluctuations that are beyond our control and could significantly increase our costs of production.

Our production processes are dependent on adequate supplies of electricity and natural gas. A substantial increase in the cost of electricity or natural gas could have a material adverse effect on our gross profit. In addition, a disruption or curtailment in supply could have a material adverse effect on our production and sales. Prices for electricity increased approximately 7% in 2014, decreased approximately 12% in 2015, in 2016 increased approximately 1.5%, in 2017 increased approximately 22% and in 2018 increased approximately 14%, and prices for natural gas increased approximately 25% in 2014, decreased approximately 23% in 2015, increased approximately 8% in 2016, increased approximately 22% in 2017 and increased approximately 28% in 2018. Moreover, energy costs constitute a significant and increasing component of our costs of operations. Our energy cost was 12.4% of our manufacturing conversion cost for 2018 compared to 13.1% for 2017, 13.5% for 2016, 13% for 2015 and 14% for 2014.

We pay special rates to the Mexican federal electricity commission (Comisión Federal de Electricidad or “CFE”) for electricity. We also pay special rates to Pemex, Gas y Petroquímica Básica, (“PEMEX”), the national oil company of Mexico, for natural gas used at our facilities in Mexico. We cannot assure you that these special rates will continue to be available to us or that these rates may not increase significantly in the future, particularly in light of recent energy reforms in Mexico. In the United States, we have contracts in place with special rates from the electric utilities. We cannot assure you that these special rates will continue to be available to us or that these rates may not increase significantly in the future. In certain deregulated electric markets in the United States, we have third party electric generation contracts under a fixed price arrangement. These contracts mitigate our price risk for electric generation from the volatility in the electric markets. In addition, we purchase natural gas from various suppliers in the United States. These purchase prices are generally established as a function of monthly New York Mercantile Exchange settlement prices. We also contract with different natural gas transportation and storage companies to deliver the natural gas to our facilities. In addition, we enter into futures contracts to fix and reduce volatility of natural gas prices both in Mexico and the United States, as appropriate. As of December 31, 2018, we have not entered into derivative financial instruments in Mexico, the United States or Brazil. We have not always been able to pass the effect of increases in our energy costs on to our customers and we cannot assure you that we will be able to pass the effect of these increases on to our customers in the future. We also cannot assure you that we will be able to maintain futures contracts to reduce volatility in natural gas prices. Changes in the price or supply of electricity or natural gas would materially and adversely affect our business and results of operations.

We face significant competition from other steel producers, which may adversely affect our profitability and market share.

Competition in the steel industry is intense, which exerts a downward pressure on prices, and, due to high start-up costs, the economics of operating a steel mill on a continuous basis may encourage mill operators to establish and maintain high levels of output even in times of low demand, which further decreases prices and profit margins. The recent trend of consolidation in the global steel industry may further increase competitive pressures on independent producers of our size, particularly if large steel producers formed through consolidations, which have access to greater resources than us, adopt predatory pricing strategies that decrease prices and profit margins. If we are unable to remain competitive with these producers, our profitability and market share would likely be materially and adversely affected.

A number of our competitors in Mexico and the United States have undertaken modernization and expansion plans, including the installation of production facilities and manufacturing capacity for certain products that compete with our products. As these producers become more efficient, we will face increased competition from them and may experience a loss of market share. In each of Mexico and the United States we also face competition from international steel producers. Increased international competition, especially when combined with excess production capacity, would likely force us to lower our prices or to offer increased services at a higher cost to us, which could materially reduce our profit margins.

Competition from other materials could significantly reduce demand and market prices for steel products.

In many applications, steel competes with other materials that may be used as steel substitutes, such as aluminum (particularly in the automobile industry), cement, composites, glass, plastic and wood. Additional substitutes for steel products could significantly reduce demand and market prices for steel products and thereby affect our results of operations.

A sudden slowdown in consumption in or increase in exports from China could have a significant impact on international steel prices, therefore affecting our profitability.

7 

As demand for steel has surged in China, steel production capacity in that market has also increased, and China is now the largest worldwide steel producing country, accounting for approximately half of the worldwide steel production. Due to the size of the Chinese steel market, a slowdown in steel consumption in that market could cause a sizable increase in the volume of steel offered in the international steel markets, exerting a downward pressure on sales and margins of steel companies operating in other markets and regions, including us.

Implementing our growth strategy, which may include additional acquisitions, may adversely affect our operations.

As part of our growth strategy, we may seek to expand our existing facilities, build additional plants, acquire additional steel production assets, enter into joint ventures or form strategic alliances that we expect will expand or complement our existing business. If we undertake any of these transactions, they will likely involve some or all of the following risks:

● disruption of our ongoing business;

● diversion of our resources and of management’s time;

● decreased ability to maintain uniform standards, controls, procedures and policies;

● difficulty managing the operations of a larger company;

● increased likelihood of involvement in labor, commercial or regulatory disputes or litigation related to the new enterprise;

● potential liability to joint venture participants or to third parties;

● difficulty competing for acquisitions and other growth opportunities with companies having greater financial resources; and

● difficulty integrating the acquired operations and personnel into our existing business.

We will require significant capital for acquisitions and other strategic plans, as well as for the maintenance of our facilities and compliance with environmental regulations. We may not be able to fund our capital requirements from operating cash flow and we may be required to issue additional equity or debt securities or obtain additional credit facilities, which could result in additional dilution to our shareholders. We cannot assure you that adequate equity or debt financing would be available to us on favorable terms or at all. If we are unable to fund our capital requirements, we may not be able to implement our growth strategy.

We intend to continue to pursue a growth strategy, the success of which will depend in part on our ability to acquire and integrate additional facilities. Some of these acquisitions may be outside of Mexico and the United States. Acquisitions involve a number of special risks, in addition to those described above, that could adversely affect our business, financial condition and results of operations, including the assumption of legacy liabilities and the potential loss of key employees. We cannot assure you that any acquisition we make will not materially and adversely affect us or that any such acquisition will enhance our business. We are unable to predict the likelihood of any additional acquisitions being proposed or completed in the near future or the terms of any such acquisitions.

We and our auditors have identified material weaknesses in our internal controls over financial reporting, for each of the last eight years, and if we fail to remediate these material weaknesses and achieve an effective system of internal controls, we may not be able to report our financial results accurately, and current and potential shareholders could lose confidence in our reporting, which would harm our business and the trading price of our Series B shares or the ADSs.

In connection with the preparation of our financial statements as of and for each of the years ended December 31, 2011, 2012, 2013, 2014, 2015, 2016, 2017 and 2018, we and our auditors identified material weaknesses (as defined under standards established by the Public Company Accounting Oversight Board, (United States of America)) in our internal controls over financial reporting (our management did not assess the effectiveness of our internal controls over financial reporting as of December 31, 2016). A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Fiscal Year Ended December 31, 2011. On January 12, 2012, our audit and corporate practices committee (“Audit Committee”) received a formal complaint from the General Accounting and Treasury Services Manager of Republic Engineered Products, Inc. (“Republic”), stating that he had identified, during his review of the financial statements of SimRep and its subsidiaries for the year ended December 31, 2011, what he considered to be material accounting errors, and potential “management override of

8 

internal controls” at SimRep. In response, our Audit Committee instructed our internal audit department to perform a review, and subsequently engaged outside counsel to conduct an internal investigation concerning the accounting matters and potential management overrides of internal controls at SimRep. As a result of our investigation, we identified material weakness at SimRep, finding that, with respect to SimRep and its subsidiaries, management did not design and maintain effective controls relating to the year-end closing and financial reporting process, resulting in accounting errors with respect to the reconciliation of certain balance sheet accounts, and a failure to timely review and control the preparation and closing of SimRep’s consolidated financial statements. In addition, SimRep also had insufficient personnel resources and technical accounting and reporting expertise to appropriately address certain accounting and financial reporting matters in accordance with generally accepted accounting principles.

In addition, our external auditors notified our management that, during their audit of our consolidated financial statements for the year ended December 31, 2011, it identified what it considered to be, under standards established by the Public Company Accounting Oversight Board, material weaknesses in internal controls over financial reporting:

● A lack of an appropriate consolidation system to allow our management to supervise properly the preparation of consolidated financial information with the required detail;

● Deficient and not standardized controls in SimRep related to authorization, control and accounting of capitalized expenditures and related fixed assets, and;

● Significant deficiencies were also detected at our subsidiary Corporación Aceros DM, S.A. de C.V. which in the aggregate, constitute a material weakness.

10 

authority of key financial roles.

Fiscal Year Ended December 31, 2014. In our assessment of our internal controls over financial reporting for the year ended December 31, 2014, we and our external auditors identified the following material weaknesses:

● Insufficient resources applied to the remediation and appropriate monitoring of internal control weaknesses, most of which were identified in previous years and continue to be unresolved.

● Inadequate distribution and segregation of duties within the accounting department in the Mexican Subsidiaries due to insufficient resources. Additionally, the internal audit staff was reduced and considered insufficient to fulfill their role.

● Inadequate supervision and controls within the accounting department which impacted the financial statement closing process, conversion of foreign subsidiaries and intercompany reconciliations, resulting in material accounting errors.

● A lack of an appropriate consolidation system to allow management to properly supervise the preparation of consolidated financial information with the detail required.

● SimRep did not maintain effective controls relating to accounting of certain capital expenditures and related fixed assets were found. Lastly, the evaluation for impairments is not reasonable given actual results of such Subsidiary.

● Significant deficiencies were also detected at our subsidiary Corporación Aceros DM, S.A. de C.V. which in the aggregate, constitute a material weakness. These significant deficiencies include (i) ineffective controls and insufficient supporting documentation for closings of periods end and financial statements review and authorization; the related procedures were incomplete and do not include specific procedures to enter transactions into the general ledger, to select and apply accounting policies and have not been updated in the last 3 years, which such controls are necessary to give reasonable assurance of compliance with IFRS, (ii) no evidence of review of some account balances, such as fixed assets, sales and tax calculations by the responsible individuals; there is also no evidence of review of the financial statements by the General Manager of Corporación Aceros DM, S.A de C.V., (iii) undocumented processes and deficient controls in the access to the information systems, (iv) deficient controls to review and approve cost calculations of finish goods, period end costs and inventories and cost of sales report, (v) lack of physical inventory of fixed assets in several years; and (vi) failure to document and communicate adequately responsibilities and authority of key financial roles.

Fiscal Year Ended December 31, 2015. In our assessment of our internal controls over financial reporting for the year ended December 31, 2015, we and our external auditors identified the following material weaknesses:

● The internal audit department did not develop its functions to comply with the analysis of the controls during 2015. Consequently, this limited the functions of the Audit Committee.

● Insufficient resources applied to the remediation and appropriate monitoring of internal control weaknesses, most of which were identified in previous years and continue to be unresolved.

11 

● Inadequate distribution and segregation of duties within the accounting department in our Subsidiaries due to insufficient resources. Additionally, the internal audit staff was considered insufficient to fulfill their role.

● Significant deficiencies were detected regarding entity-level controls and control environment which, in the aggregate, constitute a material weakness and create a reasonable likelihood that a material misstatement of our annual and interim financial statements will not be prevented or detected on a timely basis. Such deficiencies include: (i) inadequate controls for the definition, review and approval process of the disclosure in the financial statements and our annual report on form 20-F, (ii) whistleblower line for our Mexican subsidiaries was not fully operational, our website information is outdated and does not include information about our Brazilian operations, (iii) ineffective controls in our patents registry, (iv) deficient distribution of our code of ethics to employees and officers and poor promotion of strong control environment and internal controls in accordance with the COSO model, (v) failure to integrate all control processes into one Enterprise Resource Planning (ERP) system, (vi) lack of an accounting manual with accounting instructions on most of accounting records, (vii) lack of specific procedures for the approval of transactions with related parties, (viii) failure to create and implement a complete training plan for management personnel preparing financial records under IFRS, (ix) limited IFRS and consolidation process understanding and reduced personnel within our Internal Audit department which limited the scope; also the internal audit plan was not carried out, and therefore the audit department did not perform risk assessment an environmental, fraud, compliance with laws, review of the consolidated financial statements and review of our annual report on form 20-F; (x) lack of committees to review, approve and make risk assessments of all our contracts; and (xi) informal communications of deficiencies and remediation plan to the areas and managers involved.

● A lack of an appropriate consolidation system to allow management to properly supervise the preparation of consolidated financial information with the detail required.

● SimRep did not maintain personnel with the appropriate level of knowledge and experience of accounting and training required to comply with financial reporting requirements. This material weakness led to the certain control deficiencies, each of which are considered to be a material weakness.

● Failure to provide our external auditors with evidence of the evaluation of the effectiveness of internal controls in our Brazilian subsidiary, in addition of not hiring an external auditor for this evaluation.

● Significant deficiencies were also detected at our subsidiary Corporación Aceros DM, S.A. de C.V. which in the aggregate, constitute a material weakness.

Fiscal Year Ended December 31, 2016. Our external auditors incorporated into their “Attestation Report of the Independent Registered Public Accounting Firms” for the year ended December 31, 2016, the following assessment of our internal controls, which included the following material weaknesses:

● Regarding the control environment and entity level controls, the following material weaknesses were identified: (i) lack of a whistleblower tool that covers the entirety of the company; (ii) regarding the distribution of the code of ethics, certain sectors of the employees did not recognize the code of ethics; (iii) ineffective control of the patent registration process, which lacks a policy and a procedure; (iv) lack of a policy and procedure for the valuation of assets and the company’s physical inventories; (v) lack of a policy and procedure governing the extensions of credit to the clients; (vi) lack of a policy and procedure for the registration of related parties and the approval of transactions with related parties.

● In connection with certain financial reporting processes, lack of a robust role-segregation model for the creation, editing, deletion, display only, and modification of such processes.

● Lack of communication between the internal audit team, which impacted time of test execution, leaving out of scope cycles such as income, human resources, general controls of information technology and costs and inventories.

12 

● Lack of documentation setting out the procedure in the event of a disaster (Disaster Recovery Plan) and documentation setting out the procedure in order to continue the operations of the business (Business Continuity Plan).

Fiscal Year Ended December 31, 2017. In our assessment of our internal controls over financial reporting for the year ended December 31, 2017, we and our external auditors identified the following material weaknesses:

· Insufficient training on, and knowledge of, COSO and the related operation of the control environment for mid-level personnel of the Company.

· A lack of a formalized policy related to the delegation of authority clearly defining the roles and responsibilities for employees.

· The Company lacks a system of assessing and monitoring employee performance to increase their skills to be prepared for the complexity of the Company´s operation.

· The Company does not maintain a detailed accounting manual and closing checklists. The lack of such procedures reduces the likelihood of detecting errors on a timely basis during the financial close. Similarly, there is a lack of documents supporting the existence of supervisory review over accounting entries recorded by the Company.

· The Company does not maintain appropriate evidence over records supporting certain matters in regards to fixed assets:

· There is insufficient data to support certain adjustments to fixed assets recorded on the books of the Company.

· The Company does not have an appropriate system to properly store records in regards to significant acquisitions of fixed assets.

· The Company failed to reconcile their recorded fixed assets to the underlying support.

· The Company did not document appropriate authorizations in regards to capital investments or to increases in the planned size of an ongoing investment project.

· The Company has neither a system of tagging and tracking fixed assets nor a process for taking periodic inventories to determine the continued existence of recorded fixed assets.

· The Company lacks sufficient documentation and internal controls related to the process of obtaining credit. The Company also lacks sufficient training for personnel responsible for monitoring such credit facilities in regards to fraud detection and ongoing compliance matters.

· The Company lacks a program to ascertain that the administrative staff with access to accounting records are sufficiently trained and monitored.

· The Company lacks an appropriate environment to ensure that the financial records are closed in accordance with

13 

International Financial Reporting Standards properly and in a timely manner. Items identified included:

o A lack of appropriate accounting resources at the corporate level which adversely impacted the operation of key supervision controls over the accounting department, the financial statement closing process, and the process of computing and authorizing journal entries.

o A lack of appropriate procedures to analyze the results of the business units prior to consolidation.

o A lack of a unified computerized general ledger or enterprise resource planning system among the business units. There is also a lack of a common chart of accounts which would simplify the consolidation process.

o A lack of an appropriate consolidation system allowing management to properly supervise the preparation of consolidated financial information. The system is highly manual, increasing the risk of human error and lacking sufficient oversight as the process is largely performed by a single member of the accounting staff.

· An audit performed on the information technology systems of the Company determined that approximately 25% of controls over the information technology infrastructure were either deficient in design or missing. Additional findings include:

o A lack of an internal reference framework methodology to ascertain and assess information technology risks.

o The lack of a methodology to evaluate the design and operational effectiveness of key controls over critical business processes.

o No system of verification of the access profiles of personnel or a process to verify that accounts of former employees are properly closed.

· In the case of GV do Brasil Indústria e Comércio de Aco Ltda in Brasil we observed an inadequate segregation of duties, in respect to system access and activities related to:

o The person with final responsibility for the preparation of the financial reports is also responsible for the corporate tax area, financial management (approval of payments and receipts, analysis of client credit risks including credit limits still not established, and negotiations with clients), monthly calculation of the costs of the products sold (and, consequently, of the value of the inventories of finished products), and assessment of the amount of physical impurities contained in scrap inventories, which also determines the valuation.

o The person responsible for supervising the physical movements of raw materials and finished products also has the following duties: authorization to issue sales invoices, the authority to adjustment quantities of inventory items, and also responsibility for planning and authorizing the movements of the physical inventory of between inventory locations.

· In the case of SimRep Corporation and Subsidiaries in the United States we identified that as a component of the financial control process, certain accounts are not being reconciled quarterly to the underlying details and

14 

the components of certain other accounts are not being reviewed by management.

· In the case of SimRep Corporation and Subsidiaries in the United States we identified that a control requiring the signatures of the vice-president of Finance, head of information technology and the General Manager to authorize all expenditures over $25,000 was not operating effectively. A number of the purchases lacked the required supporting signatures.

· In the case of SimRep Corporation and Subsidiaries in the United States we identified that the controller at one of the production plants failed to properly perform all required tests to review the inventories to be sure they are properly recorded at the lower of cost or market, and also failed to obtain approval for a journal entry which should be generated from the analysis.

Fiscal Year Ended December 31, 2018. In our assessment of our internal controls over financial reporting for the year ended December 31, 2018, the following material weaknesses were identified:

· Transactions with related parties:

o Lack of evidence of how transactions with third parties are documented and authorized.

o Lack of policy regulating the way in which transactions with third parties should be documented and authorized.

· Information Technology Systems:

o Lack of backup-generation controls for computer equipment that contains key company information.

o Insufficient Information Technology infrastructure to support the Company’s growth when required.

By letter dated February 13, 2017, the Securities and Exchange Commission (the “SEC”) notified us that the SEC was conducting an informal, and non-public, inquiry into the Company in connection with our internal controls. After cooperating with the SEC, we settled internal controls charges with the SEC on January 29, 2019. We agreed to retain an independent consultant and to pay a civil monetary penalty in the amount of US$200,000.

Any failure to implement and maintain the needed improvements in the controls over our financial reporting, or difficulties encountered in the implementation of these improvements in our controls, could result in a material misstatement in our annual or interim financial statements that would not be prevented or detected, or cause us to fail to meet our reporting obligations under applicable securities laws. Any failure to improve our internal controls to address the identified weaknesses could result in our incurring substantial liability for not having met our legal obligation and could also cause investors to lose confidence in our reported financial information, which could have a material adverse impact on the trading price of our Series B shares or the ADSs.

For further details, see Items 15.B “Controls and Procedures—Management’s Annual Report on Internal Control Over Financial Reporting – Material Weaknesses,” 15.C “Attestation Report of the Independent Registered Public Accounting Firms” and 15.D “Changes in Internal Control over Financial Reporting.”

Tariffs, anti-dumping and countervailing duty claims imposed in the future could harm our ability to export our products outside of Mexico, and changes in Mexican tariffs on steel imports could adversely affect the profitability and market share of our Mexican steel business.

On October 14, 2014, the United States International Trade Commission (USITC) determined that the U.S. steel industry is materially injured by reason of imports of steel concrete reinforcing bars from Mexico, that are sold in the United States at less than fair value, and from Turkey, that are subsidized by the government of Turkey. As a result of the USITC’s affirmative determinations, the U.S. Department of Commerce issued an antidumping duty order on imports of this product from Mexico and a countervailing duty order on imports of this product from Turkey. The U.S. government imposed tariffs of 66.7% against imports for rebar from Deacero, S.A.P.I de C.V. and us and tariffs of 20.58% for rebar imports from all other producers in Mexico. On June 8, 2017, the US Department of Commerce issued a final resolution in which it determined that the tariff would be 0%.

Recent events, including the results of the 2016 U.S. presidential election and the lack of progress in Brexit negotiations in the U.K., have resulted in substantial regulatory uncertainty regarding international trade and trade policy. On March 1, 2018, U.S. President Trump announced a 25% tariff on all steel products and a 10% tariff on all aluminum products imported into the United States for an indefinite amount of time under Section 232 of the Trade Expansion Act. On May 1, 2018, the Trump administration issued two proclamations authorizing modifications of the Section 232 tariffs on steel and aluminum. In its May 1, 2018 proclamations, the Trump administration also extended negotiations with Canada, Mexico, and the EU for a final 30 days and, effective June 1, 2018, the Trump administration implemented 25% tariffs on imports from the EU, Canada and Mexico. It is unclear what impact these protectionist measures will have in 2019, whether they will be effective in increasing or maintaining steel prices in the adopting country or countries and whether they will have an overall negative impact on global macroeconomic conditions.

In addition, the Trump administration and the U.S. Congress may make substantial changes in legislation, regulation and government policy directly affecting our business or indirectly affecting the Company because of impacts on its customers and suppliers. In particular, the Company’s exports from Mexico into the United States may be negatively affected by the implementation of the Trump administration's replacement of the NAFTA trade agreement with Canada and Mexico. More generally, actions further to President Trump’s suggestions that he may seek to renegotiate other free trade agreements or withdraw the United States from the

15 

World Trade Organization could have an adverse effect on the Company's operations. All of the above, including escalating tariffs on steel imports or a more general trade war, pose a degree of uncertainty which could have a significant adverse effect on steel demand, our results of operations and global macroeconomic conditions generally.

Many of our products are subject to existing duties, tariffs, anti-dumping duties and quotas that may limit the quantity of some types of goods that we import into the United States. Furthermore, certain of our competitors may be better positioned than us to withstand or react to border taxes, tariffs or other restrictions on global trade and as a result we may lose market share to such competitors. Due to broad uncertainty regarding the timing, content and extent of any regulatory changes in the U.S. or elsewhere, we cannot predict the impact, if any, that these changes could have to our business, financial condition and results of operations. See “—Risks Related to Mexico—Developments in other countries could adversely affect the Mexican economy, our financial performance and the price of our shares.”

The operation of our facilities depends on good labor relations with our employees.

As of December 31, 2018, approximately 87% of our non-Mexican and 44% of our Mexican employees were members of unions. The compensation terms of our labor contracts are adjusted on an annual basis, and all other terms of the labor contracts are renegotiated every two years. In addition, collective bargaining agreements are typically negotiated on a facility-by-facility basis for our Mexican facilities. Any failure to reach an agreement on new labor contracts or to negotiate these labor contracts could result in strikes, boycotts or other labor disruptions. These potential labor disruptions could have a material and adverse effect on our business. Labor disruptions or significant negotiated wage increases could reduce our sales or increase our costs, which could in turn have a material adverse effect on our results of operations.

Operations at our Lackawanna, New York, facility depend on our continuing right to use certain property and assets of an adjoining facility and the termination of any such rights would interrupt our operations and have a material adverse effect on our results of operations and financial condition.

The operations of our Lackawanna facility depend upon certain arrangements and understandings relating to, among other things, our use of industrial water, compressed air, sanitary sewer and electrical power. These service and utility arrangements, initially entered into with the Mittal Steel Company N.V. and its affiliates (“Mittal Steel”), were effective through April 30, 2009, at which time Mittal Steel transferred its Lackawanna plant to Tecumseh Redevelopment, Inc. (“Tecumseh”). In December 2010, Tecumseh transferred a portion of the former Mittal Steel facility to Great Lakes Industrial Development, LLC (“GLID”). Upon the transfer to GLID, we entered into a written agreement with GLID regarding the provision of compressed air to our facility. This lease assures that compressed air will be provided to our facility during the lease term (initially two years with automatic one year renewals until terminated by either party) and grants us an option to purchase the equipment at various times and at stated prices, thereby providing us some flexibility while we consider the installation of our own compressed air system at our facility. The water pump that services our plant is located on property still owned by Mittal Steel and is maintained by Mittal Steel, which also continues to furnish industrial water to us on a month-to-month basis. The electric system which services the compressed air equipment, as well as the electric system which services the GLID property, has been re-routed through our electric meter located at a substation on the adjacent GLID property. We continue to pursue a written agreement with GLID covering our use of the electric substation and related equipment on the GLID property, as well as the sanitary sewer lift station on the GLID property that serves our facility, and a truck entrance and security monitoring equipment located on the GLID property. All of these rights are essential to the use and operation of our Lackawanna facility. It is our understanding that GLID has sold or is in the process of selling a portion of its property to an unrelated third party. In the event of a termination of any of our rights, either due to a failure to negotiate a satisfactory outcome with Mittal Steel, GLID or any third party to which it sells all or part of its facility, or for any other reason, we could be required to cease all or substantially all of our operations at the Lackawanna facility. Because we produce certain types of products in our Lackawanna facility that we do not produce in our other facilities, an interruption of production at our Lackawanna facility would result in a substantial loss of revenue and could damage our relationships with customers.

Our sales in the United States are concentrated and could be significantly reduced if one of our major customers reduced its purchases of our products or was unable to fulfill its financial obligations to us.

Our sales in the United States are concentrated among a relatively small number of customers. Any of our major customers can stop purchasing our products or significantly reduce their purchases at any time. During 2018, 2017, 2016, 2015 and 2014, sales to our ten largest customers in the United States accounted for approximately 68.4%, 68.7%, 62.1%, 56.8% and 51.4% of our consolidated revenues in the United States, respectively, and approximately 17.7%, 20%, 18.1%, 21.5% and 23.6% of our total consolidated revenues, respectively. A disruption in sales to one or more of our largest customers would adversely affect our cash flow and results of operations.

We cannot assure you that we will be able to maintain our current level of sales to our largest customers or that we will be able to sell our products to other customers on terms that are favorable to us or at all. The loss of, or substantial decrease in the amount

16 

of purchases by, or a write-off of any significant receivables from, any of our major customers would materially and adversely affect our business, results of operations, liquidity and financial condition.

Unanticipated problems with our manufacturing equipment and facilities could have an adverse impact on our business.

Our capacity to manufacture steel products depends on the suitable operation of our manufacturing equipment, including blast furnaces, electric arc furnaces, continuous casters, reheating furnaces and rolling mills. Breakdowns requiring significant time and/or resources to repair, as well as the occurrence of unexpected adverse events, such as fires, explosions or adverse meteorological conditions, could cause production interruptions that could adversely affect our results of operations.

We have not obtained insurance against all risks, and do not maintain insurance covering losses resulting from catastrophes or business interruptions. In the event we are not able to quickly and cost-effectively remedy problems creating any significant interruption of our manufacturing capabilities, our operations could be adversely affected. In addition, in the event any of our plants were destroyed or significantly damaged or its production capabilities otherwise significantly decreased, we would likely suffer significant losses, and capital investments necessary to repair any destroyed or damaged facilities or machinery would adversely affect our profitability, liquidity and financial condition.

If we are unable to obtain or maintain quality and environmental management certifications for our facilities, we may lose existing customers and fail to attract new customers.

Most of our automotive parts customers in Mexico and the United States require that we have ISO 9001, TS 16949 and ISO 14001 certifications. All of the Mexican and U.S. facilities that sell to automotive parts customers are currently certified, as required. If the foregoing certifications are canceled, approvals are withdrawn or necessary additional standards are not obtained in a timely fashion, our ability to continue to serve our targeted market, retain our customers or attract new customers may be impaired. For example, our failure to maintain these certifications could cause customers to refuse shipments, which could materially and adversely affect our revenues and results of operations. We cannot assure you that we will be able to maintain these required certifications.

In the SBQ market, all participants must satisfy quality audits and obtain certifications in order to obtain the status of “approved supplier.” The automotive industry has put these stringent conditions in place for the production of auto parts to assure vehicle quality and safety. We currently are an approved supplier for our automotive parts customers. Maintaining these certifications is key to preserving our market share, because they can be a barrier to entry in the SBQ market, and we cannot assure you that we will be able to do so.

Failure to comply with environmental laws and regulations may result in fines, penalties or other significant liabilities or prevent us from operating our facilities.

Our operations are subject to a broad range of environmental laws and regulations governing our impact on air, water, soil and groundwater and exposure to hazardous substances. The costs of complying with and the imposition of liabilities pursuant to, environmental laws and regulation can be significant. Despite our efforts to comply with environmental laws and regulations, environmental incidents or events that negatively affect the operations of our facilities may occur. In addition, we cannot assure you that we will at all times operate in compliance with environmental laws and regulations. If we fail to comply with these laws and regulations, we may be assessed fines or penalties, be required to make large expenditures to comply with such laws and regulations, or be forced to shut down non-compliant operations and face lawsuits by third parties. In addition, environmental laws and regulations are becoming increasingly stringent and it is possible that future laws and regulations may require us to undertake material environmental compliance expenditures and require modifications in our operations. Furthermore, we need to maintain existing and obtain future environmental permits in order to operate our facilities. The failure to obtain necessary permits or consents or the loss of any permits could result in significant fines or penalties or prevent us from operating our facilities. We may also be subject, from time to time, to legal proceedings brought by private parties or governmental agencies with respect to environmental matters, including matters involving alleged property damage or personal injury that could result in significant liability. Certain of our facilities in the United States have been the subject of administrative action by federal, state and local environmental authorities. See Item 8. “Financial Information—Legal Proceedings.”

Greenhouse gas policies and regulations, particularly any binding restriction on emissions of greenhouse gases such as carbon dioxide, could negatively impact our steelmaking operations.

Our steel making operations in the United States and in Mexico use electric arc furnaces where carbon dioxide generation is primarily linked to energy use. In the United States, the Environmental Protection Agency has issued rules imposing inventory and reporting obligations to which some of our facilities are subject, and has also issued rules that will affect preconstruction permits for our facilities where increases in greenhouse gas pollutants are contemplated. The U.S. Congress has debated various measures for

17 

regulating greenhouse gas emission (such as carbon dioxide) and may enact them in the future. Such laws and regulations may also result in higher costs for coking coal, natural gas and electricity generated by carbon-based systems (such as coal-fired electric generating facilities). Such future laws and regulations, whether in the form of a cap-and-trade emissions permit system, a carbon tax or other regulatory regime may have a negative effect on our operations. Climate change policy is evolving at regional, national and international levels, and political and economic events may significantly affect the scope and timing of climate change measures that are ultimately put in place. As signatories to the United Nations Framework Convention on Climate Change (the “UNFCCC”), Mexico and the U.S. became subject to the Paris Agreement to fight climate change, which was approved at the 21th session of the UNFCCC conference in 2015. However, in June 2017, U.S. President Trump stated that the United States would withdraw from the Paris Agreement, but may enter into a future international agreement related to greenhouse gas emissions. In August 2017, the U.S. State Department officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The United States’ adherence to the four-year exit process is uncertain and/or the terms on which the United States may reenter the Paris Agreement or a separately negotiated agreement are unclear at this time. As a result, some of our facilities may ultimately be subject to future regional, provincial and/or federal climate change regulations to manage greenhouse emissions. More stringent greenhouse gas policies and regulations could adversely affect our business and results of operations.

If we are required to remediate contamination at our facilities we may incur significant liabilities.

Certain of our U.S. facilities are currently engaged in the investigation and/or remediation of environmental contamination. Most of these investigations relate to legacy activities by prior owners. We may in the future be subject to similar investigations or required to undertake similar remediation measures at other facilities. We recognize a liability for environmental remediation when it becomes probable that such remediation will be required and the amount can be reasonably estimated. As estimated costs to remediate change, or when new liabilities become probable, we adjust the record liabilities accordingly. However, due to the numerous variables associated with the judgments and assumptions that are part of these estimates and changes in governmental regulations and environmental technologies over time, we cannot assure you that our environmental reserves will be adequate to cover such liabilities or that our environmental expenditures will not differ significantly from our estimates or materially increase in the future. Failure to comply with any legal obligations requiring remediation of contamination could result in liabilities, imposition of cleanup liens and fines, and we could incur large expenditures to bring our facilities into compliance. See Item 8. “Financial Information—Legal Proceedings.”

We could incur losses due to product liability claims and may be unable to maintain product liability insurance on acceptable terms, if at all.

We could experience losses from defects or alleged defects in our steel products that subject us to claims for monetary damages. For example, many of our products are used in automobiles and light trucks and it is possible that a defect in one of these vehicles would result in product liability claims against us. In accordance with normal commercial sales, some of our products include implied warranties that they are free from defects, are suitable for their intended purposes and meet certain agreed upon manufacturing specifications. We cannot assure you that future product liability claims will not be brought against us, that we will not incur liability in excess of our insurance coverage, or that we will be able to maintain product liability insurance with adequate coverage levels and on acceptable terms, if at all.

Our controlling shareholder, Industrias CH, S.A.B. DE C.V., (Industrias CH) is able to exert significant influence on our business and policies and its interests may differ from those of other shareholders.

As of April 29, 2019, Industrias CH, which the chairman of our board of directors, Rufino Vigil González, controls, owned approximately 84% of our shares. Industrias CH nominated and elected all of the current members of our board of directors, and Industrias CH is in a position to exercise substantial influence and control over our business and policies, including the timing and payment of dividends. The interests of Industrias CH may differ significantly from those of other shareholders. Furthermore, as a result of the significant equity position of Industrias CH, there is currently limited liquidity in our series B shares and the ADSs.

Mr. Sergio Vigil González is the chief executive officer of Industrias CH and he also functions in a senior management role for the Company, although he holds no formal title at the Company. In this function, Mr. Vigil directs business strategies for the Company, negotiates potential acquisitions and directs intercompany loans, among other things. Our board of directors is aware of Mr. Vigil’s role at the Company and he has been formally authorized by our board of directors as a signatory of the Company. Mr. Vigil is the brother of our controlling shareholder and chairman of the board of directors, Rufino Vigil González. 

We have had a number of related party transactions with our affiliates.

Historically, we have engaged in a number and variety of transactions with our affiliates, including entities that Industrias CH owns or controls. While we believe that these transactions were made on terms that were not less favorable to us than those obtainable on an arm’s length basis, there was no independent determination of that fact. We expect that in the future we will continue to enter into transactions with our affiliates, and some of these transactions may be significant. See Item 7.B “Related Party Transactions.”

We depend on our senior management and their unique knowledge of our business and of the SBQ industry, and we may not be able to replace key executives if they leave.

18 

We depend on the performance of our executive officers and key employees. Our senior management has significant experience in the steel industry, and the loss of any member of senior management or our inability to attract and retain additional senior management could materially and adversely affect our business, results of operations, prospects and financial condition. We believe that the SBQ steel market is a niche market where specific industry experience is key to success. We depend on the knowledge of our business and the SBQ industry of our senior management team, including Luis Garcia Limon, our chief executive officer. In addition, we attribute much of the success of our growth strategy to our ability to retain most of the key senior management personnel of the companies and businesses that we have acquired. Competition for qualified personnel is significant, and we may not be able to find replacements with sufficient knowledge of, and experience in, the SBQ industry for our existing senior management or any of these individuals if their services are no longer available. Our business could be adversely affected if we cannot attract or retain senior management or other necessary personnel.

Our tax liability may increase if the tax laws and regulations in countries in which we operate change or become subject to adverse interpretations.

Taxes payable by companies in the countries in which we operate are substantial and include income tax, value-added tax, excise duties, profit taxes, payroll related taxes, property taxes and other taxes. Tax laws and regulations in some of these countries may be subject to change, varying interpretation and inconsistent enforcement. Ineffective tax collection systems and continuing budget requirements may increase the likelihood of the imposition of onerous taxes and penalties which could have a material adverse effect on our financial condition and results of operations. In addition to the usual tax burden imposed on taxpayers, these conditions create uncertainty as to the tax implications of various business decisions. This uncertainty could expose us to significant fines and penalties and to enforcement measures despite our best efforts at compliance, and could result in a greater than expected tax burden. In addition, many of the jurisdictions in which we operate, including Mexico, have adopted transfer pricing legislation. If tax authorities impose significant additional tax liabilities as a result of transfer pricing adjustments, it could have a material adverse effect on our financial condition and results of operations. It is possible that tax authorities in the countries in which we operate will introduce additional tax raising measures. The introduction of any such provisions may affect our overall tax efficiency and may result in significant additional taxes becoming payable. Any such additional tax exposure could have a material adverse effect on our financial condition and results of operations.

If we are unable to protect our information systems against data corruption, cyber-based attacks or network security breaches, our operations could be disrupted.

We are increasingly dependent on information technology networks and systems, including over the Internet, to process, transmit and store electronic information. In particular, we depend on our information technology infrastructure for digital marketing activities and electronic communications among us and our clients, suppliers and also among our subsidiaries and facilities. Security breaches or infrastructure flaws can create system disruptions, shutdowns or unauthorized disclosure of confidential information. If we are unable to prevent such breaches or flaws, our operations could be disrupted, or we may suffer financial damage or loss because of lost or misappropriated information.

Cyber threats are rapidly evolving and those threats and the means for obtaining access to information in digital and other storage media are becoming increasingly sophisticated. Cyber threats and cyber-attackers can be sponsored by countries or sophisticated criminal organizations or be the work of single “hackers” or small groups of “hackers.”

Insider or employee cyber and security threats are increasingly a concern for all companies, including ours. Nevertheless, as cyber threats evolve, change and become more difficult to detect and successfully defend against, one or more cyber-attacks might defeat our or a third-party service provider's security measures in the future and obtain the personal information of customers or employees. Employee error or other irregularities may also result in a defeat of security measures and a breach of information systems. Moreover, hardware, software or applications we use may have inherent defects of design, manufacture or operations or could be inadvertently or intentionally implemented or used in a manner that could compromise information security. A security breach and loss of information may not be discovered for a significant period of time after it occurs. While we have no knowledge of a material security breach to date, any compromise of data security could result in a violation of applicable privacy and other laws or standards, the loss of valuable business data, or a disruption of our business. A security breach involving the misappropriation, loss or other unauthorized disclosure of sensitive or confidential information could give rise to unwanted media attention, materially damage to our customer relationships and reputation, and result in fines, fees, or liabilities, which may not be covered by our insurance policies.

Risks Related to Global Economic Conditions

Global economic conditions, such as the latest financial crisis and economic recession that occurred during 2008 and 2009, may significantly impact our business.

19 

The financial crisis that began in the United States in 2008 led to a global recession in which overall economic activity decreased across the world generally and in North America in particular. The corresponding reduction in demand across the economy in general and in the automotive, construction and manufacturing sectors in particular has reduced demand for steel products in North America and globally. These economic conditions significantly impacted our business and results of operations. Although demand, production levels and prices in certain segments and markets have recovered and stabilized to a certain degree, the extent, timing and duration of the recovery and potential return to pre-crisis levels remains uncertain. If global macroeconomic conditions deteriorate, however, the outlook for steel producers would be adversely affected. It is difficult to predict the duration or severity of a new global economic downturn, or to what extent it will affect us. An unsustainable recovery and persistently weak economic conditions in our key markets could depress demand for our products and adversely affect our business and results of operations. We sell our products to the automotive and construction-related industries, both of which reported substantially lower customer demand during and after the latest global recession. As a result, our operating levels declined compared to pre-recession levels. While some of our end-product markets, such as the automotive industry, experienced recoveries during 2013, 2014 and 2015, in 2016 we experienced a reduction in our sales, and in 2017 there was a slight increase in sales to the automotive industry compared to 2016, in 2018 we experienced a slight decrease in our sales to the automotive industry compared to 2017. In addition to slackening demand by end consumers, we believe that some of our customers continue to experience and may experience in the future difficulty in obtaining credit or maintaining their ability to qualify for trade credit insurance, resulting in a further reduction in purchases and an increase in our credit risk exposure. Moreover, if a new global economic downturn occurs, we may face increased risk of insolvency and other credit related issues of our customers and suppliers, as we faced with our customers and suppliers particularly in industries that were hard hit by the latest recession, such as automotive, construction and appliance. Also, there is the possibility that our suppliers may face similar risks. A decrease in available credit may increase the risk of our customers defaulting on their payment obligations to us and may cause some of our suppliers to be delayed in filling or to be unable to fill our needs. The impact of global economic conditions on these industries may have a significant effect on our results of operations.

Additionally, if global economic conditions deteriorate, we may be required to undertake asset impairments, as we have been required to undertake in the past.

Because a significant portion of our sales are to the automotive industry, a decrease in automotive manufacturing could reduce our cash flows and adversely affect our results of operations.

Direct sales of our products to automotive assemblers and manufacturers accounted for approximately 65% of our net sales of SBQ in 2018. Demand for our products is affected by, among other things, the relative strength or weakness of the North American automotive industry. A reduction in vehicles manufactured in North America, the principal market for Republic’s SBQ steel products, would have an adverse effect on our results of operations. We also sell to independent forgers, components suppliers and steel service centers, all of which sell to the automotive market as well as other markets. Developments affecting the North American automotive industry may adversely affect us.

Our customers in the automotive industry continually seek to obtain price reductions from us, which may adversely affect our results of operations.

A challenge that we and other suppliers of intermediary products used in the manufacture of automobiles face is continued price reduction pressure from our customers in the automobile manufacturing business. Downward pricing pressure has been a characteristic of the automotive industry in recent years and it is migrating to all our vehicular markets. Virtually all automobile manufacturers have aggressive price reduction initiatives that they impose upon their suppliers, and such actions are expected to continue in the future. In the face of lower prices to customers, we must continue to reduce our operating costs in order to maintain profitability. We have taken and continue to take steps to reduce our operating costs to offset customer price reductions; however, price reductions are adversely affecting our profit margins and are expected to do so in the future. If we are unable to offset customer price reductions through improved operating efficiencies, new manufacturing processes, sourcing alternatives, technology enhancements and other cost reduction initiatives, or if we are unable to avoid price reductions from our customers, our results of operations could be adversely affected.

Sales may fall as a result of fluctuations in industry inventory levels.

Inventory levels of steel products held by companies that purchase our products can vary significantly from period to period. These fluctuations can temporarily affect the demand for our products, as customers draw from existing inventory during periods of low investment in construction and the other industry sectors that purchase our products and accumulate inventory during periods of high investment and, as a result, these companies may not purchase additional steel products or maintain their current purchasing volume. Accordingly, we may not be able to increase or maintain our current levels of sales volumes or prices.

Risks Related to Mexico

Adverse economic conditions in Mexico may adversely affect our financial performance.

A substantial portion of our operations are conducted in Mexico and our business is affected by the performance of the Mexican economy. The latest global credit crisis and the economic recession has had significant adverse consequences on the Mexican economy, which in 2009 contracted by 6.5%, in 2010 grew by 5.5%, in 2011 and 2012 grew by 3.9%, in 2013 grew by 1.1%, in 2014 grew by 2.3%, in 2015 grew 2.5%, in 2016 grew by 2.9% in 2017 grew by 2% and in 2018 grew by 2% (according to preliminary figures of the Instituto Nacional de Estadística y Geografía (INEGI)), in terms of gross domestic production. Moreover, in the past, Mexico has experienced prolonged periods of economic crises, caused by internal and external factors over which we have no control. Those periods have been characterized by exchange rate instability, high inflation, high domestic interest rates, changes in oil prices, economic contraction, a reduction of international capital flows, balance of payment deficits, a reduction of liquidity in the banking sector and high unemployment rates. Decreases in the growth rate of the Mexican economy, or periods of negative growth, or increases in inflation may result in lower demand for our products. The Mexican government recently cut spending in response to a downward trend in international crude oil prices, and it may further cut spending in the future. These cuts could adversely affect the Mexican economy and, consequently, our business, financial condition, operating results and prospects. We cannot assure you that economic conditions in Mexico will not worsen, or that those conditions will not have an adverse effect on our financial performance.

Political, social and other developments in Mexico could adversely affect our business.

Political, social and other developments in Mexico may adversely affect our business. Social unrest, such as strikes, suspension of labor, demonstrations, acts of violence and terrorism in the Mexican states in which we operate could disrupt our financial performance. Additionally, the Mexican government has exercised, and continues to exercise, significant influence over the economy. Accordingly, Mexican federal governmental actions and policies concerning the economy, the regulatory framework, the social or political context, and state-owned and stated controlled entities or industries could have a significant impact on private sector companies and on market conditions, prices and returns of Mexican securities. In the past, governmental actions have involved, among other measures, increases in interest rates, changes in tax policies, price controls, currency devaluations, capital controls and limits on imports.

Presidential and federal congressional elections in Mexico were held on July 1, 2018. Mr. Andrés Manuel López Obrador, a member of the Movimiento Regeneración Nacional (National Regeneration Movement, or Morena), was elected President of Mexico and took office on December 1, 2018, replacing Mr. Enrique Peña Nieto, a member of the Partido Revolucionario Institucional (Institutional Revolutionary Party, or PRI). The new President’s term will expire on September 30, 2024. The newly-elected members of the Mexican Congress took office on September 1, 2018. The uncertainty regarding the direction of policymaking with the new government could significantly change Mexico’s political and economic situation, which consequently could affect our operations. As of the date of this annual report, the National Regeneration Movement holds an absolute majority in the Chamber of Deputies and controls 19 of 32 Mexican state congresses. This should facilitate the passing of legislation, including potential changes to the Mexican Constitution, which may increase political uncertainty. We cannot provide any assurances that political developments in Mexico, over which we have no control, will not have an adverse effect on our business, financial condition or results from operations. We cannot assure you that the current political situation or future developments in Mexico, over which we have no control, will not have an adverse effect on our business, financial condition or results of operations. Further, we cannot assure you that any new government policies will not adversely affect our business, financial condition and results of operations.

The Mexican government has exercised, and continues to exercise, significant influence over the Mexican economy.

The Mexican federal government has exercised, and continues to exercise, significant influence over the Mexican economy. Accordingly, Mexican federal governmental actions and policies concerning the economy, state-owned enterprises and state controlled, funded or influenced financial institutions could have a significant impact on private sector entities in general and on us in particular, and on market conditions, prices and returns on securities of Mexican companies. The Mexican federal government occasionally makes significant changes in policies and regulations, and may do so again in the future. Actions to control inflation and other regulations and policies have involved, among other measures, increases in interest rates, changes in tax policies, price controls, currency devaluations, capital controls and limits on imports. Tax legislation in Mexico is subject to continuous change and we cannot assure you whether the Mexican government may maintain existing political, social, economic or other policies, or whether changes may have a material adverse effect on our financial performance.

Violence in Mexico may adversely impact the Mexican economy and have a negative effect on our financial performance.

Mexican drug related violence and other organized crime have escalated significantly since 2006, when the Mexican federal government began increasing the use of the army and police to fight drug trafficking. Drug cartels have carried out attacks largely directed at competing drug cartels and law enforcement agents, however they also target companies and their employees, including companies’ industrial properties, including through extortion, theft from trucks or industrial sites, kidnapping and other forms of crime and violence. This increase in violence and criminal activity has led to increased costs for companies in the form of stolen products

21 

and added security and insurance. Corruption and links between criminal organizations and authorities also create conditions that affect our business operations, as well as extortion and other acts of intimidation, which may have the effect of limiting the level of action taken by federal and local governments in response to such criminal activity. We cannot assure you that the levels of violent crime in Mexico, over which we have no control, will not have an adverse effect on the country’s economy and, as a result, on our financial performance.

Depreciation of the Mexican peso relative to the U.S. dollar could adversely affect our financial performance.

The peso historically has been subject to significant depreciation against the U.S. dollar. Depreciation of the Mexican peso relative to the U.S. dollar decreases a portion of our revenues in U.S. dollar terms, as well as increases the cost of a portion of the raw materials we require for production and any debt obligations denominated in U.S. dollars, and thereby may negatively affect our results of operations. The Mexican Central Bank may from time to time participate in the foreign exchange market to minimize volatility and support an orderly market. The Mexican Central Bank and the Mexican government have also promoted market-based mechanisms for stabilizing foreign exchange rates and providing liquidity to the exchange market, such as using over-the-counter derivatives contracts and publicly-traded futures contracts on the Chicago Mercantile Exchange. However, the Peso is currently subject to significant fluctuations against the U.S. dollar and may be subject to such fluctuations in the future. Since the second half of 2008, the value of the Mexican peso relative to the U.S. dollar has fluctuated significantly. According to the U.S. Federal Reserve Board, during this period the exchange rate registered a low of Ps. 9.91 to U.S.$1.00 on August 5, 2008, and a high of Ps. 21.89 to U.S.$1.00 on January 19, 2017. In 2018 the exchange rate registered a low of Ps. 17.97 to U.S.$1.00 and a high of Ps. 20.67 to U.S.$1.00.

A severe depreciation of the Mexican peso may also result in disruption of the international foreign exchange markets and may limit our ability to transfer and to convert Mexican pesos into U.S. dollars and other currencies. While the Mexican government does not currently restrict, and since 1982 has not restricted the right or ability of Mexican or foreign persons or entities to convert Mexican pesos into U.S. dollars or to transfer other currencies out of Mexico, the Mexican government could impose restrictive exchange rate policies in the future.

Currency fluctuations or restrictions on transfer of funds outside Mexico may have an adverse effect on our financial performance, and could adversely affect the U.S. dollar value of the price of our Series B shares and the ADSs.

On December 17, 2015, a day after the U.S. Federal Reserve increased the target range for the federal funds rate in the United States by 25 basis points, the Mexican Central Bank increased the reference rate from 3.00% to 3.25% in an effort to counteract a sharp depreciation of the Mexican peso that could affect Mexico’s expected rate of inflation. On February 17, 2016, the Mexican Central Bank further increased the reference rate from 3.25% to 3.75%, and has been increasing the reference rate regularly since then, to 8.25% as of March 26, 2019. We cannot assure you that, as a result of future increases by U.S. Federal Reserve of the target range for the federal funds rate in the United States, the Mexican economy or the value of securities issued by Mexican companies will not be affected, including as a result of any precipitous unwinding of investments in emerging markets, depreciations and increased volatility in the value of their currency and higher interest rates.

High inflation rates in Mexico may affect demand for our products and result in cost increases.

Mexico has historically experienced high annual rates of inflation. The annual rate of inflation, as measured by changes in the Mexican national consumer price index (Índice Nacional de Precios al Consumidor) published by the INEGI was 4.1% for 2014, 2.1% for 2015, 3.4% for 2016, 6.8% for 2017 and 4.8% for 2018. High inflation rates could adversely affect our business and results of operations by reducing consumer purchasing power, thereby adversely affecting demand for our products, increasing certain costs beyond levels that we could pass on to consumers, and by decreasing the benefit to us of revenues earned if the inflation rate exceeds the growth in our pricing levels.

Developments in other countries could adversely affect the Mexican economy, our financial performance and the price of our shares.

The Mexican economy and the market value of Mexican companies may be, to varying degrees, affected by economic and market conditions globally, in other emerging market countries and major trading partners, in particular the United States. Although economic conditions in other countries may differ significantly from economic conditions in Mexico, investors’ reactions to adverse developments in other countries may have an adverse effect on the market value of securities of Mexican issuers or of Mexican assets. In recent years, for example, prices of both Mexican debt securities and equity securities decreased substantially as a result of developments in Russia, Asia, Europe and Brazil. Also, credit issues in the United States have in the past resulted in significant fluctuations in global financial markets, including Mexico.

22 

In addition, in recent years economic conditions in Mexico have become increasingly correlated with economic conditions in the United States as a result of the North American Free Trade Agreement, or NAFTA, increased economic activity between the two countries, and the remittance of funds from Mexican immigrants working in the United States to Mexican residents. However, Donald Trump’s victory in the U.S. presidential election in November 2016 has created uncertainty regarding the future of NAFTA and trade between the U.S. and Mexico. On January 20, 2017, Donald Trump became president of the U.S. President Trump and the Trump administration have made comments suggesting that he intends to re-negotiate the free trade agreements that the U.S. is party to, including NAFTA, and to implement high import taxes. On March 1, 2018, President Trump announced a 25% tariff on all steel products and a 10% tariff on all aluminum products imported into the United States for an indefinite amount of time under Section 232 of the Trade Expansion Act. In addition, leaders from the United States, Canada and Mexico also commenced discussions regarding NAFTA on January 23, 2018 in Montreal, Canada. In November 2018, the United States, Mexico and Canada signed the United States-Mexico-Canada Agreement, or USMCA, which is designed to replace NAFTA. The USMCA remains subject to approval and ratification by the legislatures in each of the three countries. If the United States fails to ratify the USMCA and withdraws from NAFTA, or if the United States withdraws from or makes material changes to other international trade agreements to which it is a party, trade barriers and other costs associated with trade between the United States and Mexico may increase, which could have a material adverse effect on our business, financial condition and results of operations.

Moreover, the debt crisis in the European Union, changes in Chinese exchange rate policy, continuing concerns regarding the slowdown of the Chinese economy, recent terrorist attacks and recent sharp declines in the price of crude oil, may also affect the global and Mexican economies. We cannot assure you that events in other emerging market countries, in the United States or elsewhere will not adversely affect our financial performance.

We could be adversely affected by violations of the Mexican Federal Anticorruption Law in Public Contracting, the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws.

The Mexican Federal Anticorruption Law (Ley Federal de Anticorrupción en Contrataciones Públicas), the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws generally prohibit companies and their intermediaries from making improper payments to government officials and other persons for the purpose of obtaining or retaining business. There can be no assurance that our internal control policies and procedures will protect us from reckless or criminal acts committed by our employees or agents. Violations of these laws, or allegations of such violations, could disrupt our business and could have an adverse effect on our business, financial condition and results of operations.

Our financial statements are prepared in accordance with IFRS and therefore are not directly comparable to financial statements of other companies prepared under U.S. GAAP or other accounting principles.

All Mexican companies listed on the Mexican Stock Exchange must prepare their financial statements in accordance with IFRS which differs in certain significant respects from U.S. GAAP. Items on the financial statements of a company prepared in accordance with IFRS may not reflect its financial position or results of operations in the way they would be reflected had such financial statements been prepared in accordance with U.S. GAAP. Accordingly, Mexican financial statements and reported earnings are likely to differ from those of companies in other countries in this and other respects.

Mexico has different corporate disclosure and accounting standards than those in the United States and other countries.

A principal objective of the securities laws of the United States, Mexico and other countries is to promote full and fair disclosure of all material corporate information, including accounting information. However, there may be different or less publicly available information about issuers of securities in Mexico than is regularly made available by public companies in countries with more highly developed capital markets, including the United States. The disclosure standards imposed by the Mexican Stock Exchange may be different than those imposed by securities exchanges in other countries or regions such as the United States. As a foreign private issuer, we are not subject to U.S. proxy rules and are exempt from certain reports under the U.S. Securities Exchange Act of 1934, as we are not required to file annual, quarterly and current reports and financial statements with the SEC as frequently or as promptly as U.S. domestic reporting companies whose securities are registered under the Exchange Act. These exemptions and leniencies will reduce the frequency and scope of information and protections available to you in comparison to those applicable to a U.S. domestic reporting company.

Risks Related to Brazil

Brazilian political and economic conditions, and the Brazilian government’s economic and other policies, may negatively affect demand for our products.

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 and implement other policies have at times involved wage and price controls, blocking access to bank accounts, imposing capital controls and limiting imports into Brazil.

23 

Our results of operations and financial condition may be adversely affected by factors such as:

● fluctuations in exchange rates;

● exchange control policies;

● interest rates;

● inflation;

● tax policies;

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

● liquidity of domestic capital and lending markets; and

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

Brazilian markets have been experiencing heightened volatility due to the uncertainties derived from the ongoing Lava Jato investigation, which is being conducted by the Office of the Brazilian Federal Prosecutor, and its impact on the Brazilian economy and political environment. Members of the Brazilian federal government and of the legislative branch, as well as senior officers of the state-owned oil company Petróleo Brasileiro S.A. – Petrobras, have faced allegations of political corruption. These government officials and senior officers allegedly accepted bribes by means of kickbacks on contracts granted by Petrobras to several infrastructure, oil and gas and construction companies. As a result of the Lava Jato investigation, a number of senior politicians, including congressman and officers of the major state-owned companies in Brazil resigned or have been arrested.

The potential outcome of these investigations and proceedings is uncertain, but they have adversely affected and we expect that they will continue to adversely affect the Brazilian markets. We cannot predict whether the allegations or proceedings will lead to further political and economic instability or whether new allegations against government officials or other companies in Brazil will arise in the future. In addition, we can neither predict the outcome of any such allegations and proceedings nor their effect on the Brazilian economy.

Amidst this background of political uncertainty, in August 2016, the Brazilian Senate approved the removal from office of Brazil’s then-President, Dilma Rousseff, following a legal and administrative impeachment process for infringement of budgetary laws. Michel Temer, the former Vice-President, who assumed the presidency of Brazil following Rousseff’s ouster, is also under investigation on corruption allegations. In addition, the former President, Luiz Inacio Lula da Silva, began serving a 12-year prison sentence on corruption and money laundering charges in April 2018 yet had led for a while the polls as a top contender to win the 2018 presidential election. On October 28, 2018, Jair Bolsonaro, a former member of the military and three-decade congressman, was elected the president of Brazil and took office on January 1, 2019. During his presidential campaign, Bolsonaro was reported to favor the privatization of state-owned companies, economic liberalization, and social security and tax reforms. However, there is no guarantee that Bolsonaro will be successful in executing his campaign promises or passing certain favored reforms fully or at all, particularly when confronting a fractured congress. In February 2019, the Brazilian federal government presented to the Congress a bill proposing a large and comprehensive change of Brazil’s public social security system. If some or all of these public expenses are maintained and the required reforms are not passed, Brazil will continue to run a budget deficit for 2019 and the years going forward. We cannot predict the effects of this budget deficit on the Brazilian economy. We cannot predict which policies the Brazilian federal government may adopt or change 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 impact on our business, results of operations, financial condition and prospects. In addition, his current minister of the economy, Paulo Guedes, proposed during the presidential campaign the revocation of income tax exemption over payment of dividends, which, if enacted, would increase the tax expenses associated with any dividend or distribution by Brazilian companies, which could impact our capacity to receive, from our subsidiaries, future cash dividends or distributions net of taxes. Moreover, Bolsonaro was generally a polarizing figure during his campaign for presidency, particularly in relation to certain of his behavioral views, and we cannot predict the ways in which a divided electorate may continue to impact his presidency and ability to implement policies and reforms, all of which could have a negative impact on our business

In addition, the Brazilian steel sector is facing a severe crisis. According to the Brazilian Steel Institute, steel consumption fell by 14% in the first nine months of 2015. We believe this crisis is largely due to a sharp decrease in durable goods manufacturing, particularly motor vehicle production, which is depressing steel consumption and offsetting the positive impact of construction activity associated with the summer 2016 Olympic Games held in Rio de Janeiro. The crisis in the Brazilian steel sector could have a material and adverse effect on our Brazilian business segment.

24 

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 National Extended Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo), published by the IBGE, the Brazilian price inflation rates were 6.2% in 2014, 11.3% in 2015, 6.6% in 2016, 2.95% in 2017 and 3.43% in 2018.  

However, the Brazilian real currency (“BRL”) remains very sensitive to political developments. For example, it depreciated by -9% against the U.S. dollar the day after the Temer scandal surfaced. Although the disinflation process is expected to continue over the next months, allowing for further rate cuts, short-term risks should be closely monitored such as (i) the impact on prices of the approval of fiscal consolidation measures, (ii) the uncertain external environment and its impact on the currency and (iii) shocks on food prices stemming to a large extent from unfavorable weather conditions.

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 Brazilian real depreciated again approximately 31.9% against the U.S. dollar. In 2009, the Brazilian real appreciated 25.3% against the U.S. dollar, while in December 31, 2010 the Brazilian real to U.S. dollar exchange rate was R$1.6662, according to the Brazilian Central Bank. In 2011, the Brazilian 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 Brazilian 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 Brazilian 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 Brazilian real went from R$2.3975 in the beginning of the year to R$2.6652 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 Brazilian real has devalued at a rate that is much higher than in previous years. On September 24, 2015, the Brazilian real fell to the lowest level since the introduction of the currency, at R$4.1949 per U.S.$1.00. In 2015, the Brazilian real depreciated 45%, reaching R$3.9048 per U.S.$1.00 on December 31, 2015. Conversely, in 2016, the Brazilian 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 Brazilian real went from R$3.2591 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 depreciation of 1.5% against the U.S. dollar. In 2018, the Brazilian real went from R$3.3080 per U.S.$1.00 at the beginning of the year to R$3.8748 per U.S.$1.00 on December 31, 2018, corresponding to a depreciation of 17.1% against the U.S. dollar. There can be no assurance that the Brazilian real will not depreciate or appreciate further against the U.S. dollar.

Furthermore, the Brazilian economy has experienced a sharp downturn in recent years due, in part, to the interventionist economic and monetary policies of the Brazilian government and the global drop in commodity prices. The current Brazilian federal government is expected to propose the general terms of a fiscal reform to stimulate the economy and reduce the forecasted budget deficit for 2019, but it is uncertain whether the Brazilian government will be able to gather the required support in the Brazilian Congress to pass additional specific reforms. As of the date of this annual report, many of the proposed public expenses in Brazil’s budget have been maintained and it is not clear whether other expenses will be reduced or entirely eliminated. If some or all of these public expenses are maintained, Brazil will continue to run a budget deficit for 2019 and the years going forward. We cannot predict the effects of this budget deficit on the Brazilian economy. We cannot predict which policies the Brazilian federal government may adopt or change 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 impact on our business, results of operations, financial condition and prospects.

Uncertainty as to whether the Brazilian government will implement changes in policy or regulations affecting these or other factors in the future may contribute to economic uncertainty in Brazil and to heightened volatility in the Brazilian securities markets.

Item 4. Information on the Company

A. History and Development of the Company

Overview

We are a diversified manufacturer, processor and distributor of SBQ steel and structural steel products with production and commercial operations in the United States, Mexico and Brazil. We believe that in 2014, 2015, 2016, 2017 and 2018 we were an important producer of SBQ products in both the United States and Mexico, in each case in terms of shipped volume. We also believe

25 

that in 2014, 2015, 2016, 2017 and 2018 we were an important producer of structural and light structural steel products in Mexico in terms of shipped volume.

Our SBQ products are used across a broad range of highly engineered end-user applications, including axles, hubs and crankshafts for automobiles and light trucks, machine tools and off-highway equipment. Our structural steel products are mainly used in the non-residential construction market and other construction applications.

We focus on the Mexican and U.S. specialty steel markets by providing high value added products and services from our strategically located plants. The quality of our products and services, together with cost benefits generated by our facility locations, has allowed us to develop long standing relationships with many of our SBQ clients, which include Mexico and U.S.-based automotive and industrial equipment manufacturers and their suppliers. In addition, our facilities located in the North West and Central parts of Mexico allow us to serve the structural steel and construction markets in those regions and South West California with an advantage in the cost of freight over competitors which do not have production facilities in such regions.

Our legal name is Grupo Simec, S.A.B. de C.V. and our commercial name for advertising and publicity purposes is Simec. We are a sociedad anónima bursátil de capital variable, organized under the laws of Mexico. We are domiciled in the city of Guadalajara, Jalisco, and our principal administrative office is located at Calzada Lázaro Cárdenas 601, Guadalajara, Jalisco, Mexico 44440. Our telephone number is +52-33-3770-6700.

Our History

Our steel operations commenced in 1969 when a group of families from Guadalajara, Jalisco, formed Compañía Siderúrgica de Guadalajara, S.A. de C.V. (“CSG”), a mini-mill steel company. In 1980, Grupo Sidek, S.A. de C.V. (“Sidek”), our former parent company, was incorporated and became the holding company of CSG. In 1990, Sidek consolidated its steel and aluminum operations into a separate subsidiary, Grupo Simec, S.A. de C.V., a Mexican corporation with limited liability, organized under the laws of Mexico.

In March 2001, Sidek consummated the sale of its entire approximate 62% controlling interest in our company to Industrias CH. In June 2001, Industrias CH increased its interest in us to 82.5% by acquiring additional shares from certain of our bank creditors that had converted approximately Ps. 1,185 million (U.S.$95.4 million) of our debt (U.S.$90.2 million of principal and U.S.$5.2 million of interest) into our common shares. Industrias CH subsequently increased its equity position in us through various conversions of debt to equity and capital contributions, to an 84% interest.

In August 2004, we acquired the property, plant and equipment and the inventories, and assumed liabilities associated with the seniority premiums of employees, of the Mexican steel-making facilities of Industrias Ferricas del Norte S.A. (Corporacion Sidenor of Spain, or “Grupo Sidenor”) located in Apizaco, Tlaxcala and Cholula, Puebla. We refer to this acquisition as the “Atlax Acquisition.” Our total net investment in this transaction was approximately Ps. 1,589 million (U.S.$122 million) (excluding value added tax of approximately Ps. 208 million (U.S.$16 million) paid in 2004 and recouped from the Mexican government in 2005), funded with cash from operations, and a Ps. 247 million (U.S.$19 million) capital contribution from Industrias CH.

In July 2005, we and Industrias CH acquired 100% of the capital stock of Republic, a U.S. producer of SBQ steel. We acquired 50.2% of Republic’s stock through our majority owned subsidiary, SimRep, and Industrias CH purchased the remaining 49.8% through SimRep. We financed our portion of the Ps. 2,795 million (U.S.$245 million) purchase price principally through a loan we received from Industrias CH that we have repaid in full.

On October 9, 2006 we sold our share ownership in Administradora de Cartera de Occidente, S.A. de C.V. (“ACOSA”). ACOSA engaged in the recovery of non-performing loans acquired pursuant to a public bidding process conducted by the Instituto de Protección al Ahorro Bancario in Mexico.

On November 24, 2007 we purchased 99.95% of the shares of three subsidiaries of Grupo TMM S.A de C.V. These three subsidiaries were TMM América, S.A. de C.V., TMM Continental, S.A. de C.V. and Mutimodal Doméstica, S.A. de C.V. Following the purchase, these companies have engaged in marketing steel. In February 2008, the names of these three companies were changed to CSG Comercial, S.A. de C.V., Comercializadora de Productos de Acero de Tlaxcala, S.A. de C.V. and Siderúrgica de Baja California, S.A. de C.V.

In 2007, the board of directors of CSG decided to spin-off CSG. CSG conveyed 87.4% of its stockholders equity to Tenedora CSG, S.A. de C.V, as the spun-off company. This corporate restructuring did not have a material effect on our consolidated financial statements.

26 

On May 30, 2008, we acquired all the capital stock of Aceros DM and certain affiliated companies (“Grupo San”) for a total cost of approximately Ps. 8,730 million (U.S.$844 million at the exchange rate at that time). Grupo San is a long products steel mini-mill and the second-largest corrugated rebar producer in Mexico. Grupo San’s operations are based in San Luis Potosí, Mexico. Its plants have a production capacity of 700 thousand tons of finished products annually.

On July 29, 2008, the company acquired 100% of the shares of Aroproc, S. A. de C. V., Del-Ucral, S. A. de C. V., Qwer, S. A. de C. V. and Transporte Integral Doméstico, S.A. de C.V., subsidiaries of Grupo TMM, S. A. de C. V., to convert them into the operating manager of the steel plants located in Mexico. On July 30 2008, these companies were renamed to Promotora de Aceros San Luis, S.A. de C.V., Comercializadora Aceros DM, S.A. de C.V., Comercializadora Msan, S.A. de C.V. and Productos Siderúrgicos de Tlaxcala, S.A. de C.V. respectively.

On December 26, 2008, the company acquired 99.95% of the shares of Northarc Express, S.A. de C.V., a subsidiary corporation of Grupo TMM, S.A. de C.V., to convert this company into the operating manager of iron and steel plants located in Mexico. On January 6, 2009, this company changed its name to Simec International 2, S.A. de C.V.

On February 5, 2009, Simec International 2, S.A. de C.V. divested assets and liabilities to three new wholly owned Mexican subsidiaries. As a consequence of such reorganization, Simec International 3, S.A. de C.V. operated the Tlaxcala and Puebla facilities, Simec International 4, S.A. de C.V. and Simec International 5, S.A. de C.V jointly operated the San Luis de Potosí facilities, and Simec International 2, S.A. de C.V. operated the Guadalajara and Mexicali facilities.

In 2009 we incorporated two new wholly owned subsidiaries. Simec Acero, S.A. de C.V. distributes all Grupo Simec products in Mexico and Simec USA, Corp. is responsible for all export sales of our Mexican companies.

On May 12, 2009, we incorporated Pacific Steel Projects, Inc., a wholly owned subsidiary organized under the laws of the State of California whose purpose is to develop technology improvement projects for our Mexican facilities.

On August 10, 2009, Simec International, S.A. de C.V. divested assets and liabilities to four new wholly owned Mexican subsidiaries named Siminsa A, S.A. de C.V., Siminsa B, S.A. de C.V., Siminsa C, S.A. de C.V. and Siminsa D, S.A. de C.V. After the divesture, Siminsa A was merged into Simec International 2, Siminsa B was merged into Simec International 3, Siminsa C was merged into Simec International 4 and Siminsa D was merged into Simec International 5.

On November 10, 2009, Simec International 2, Simec International 3, Simec International 4 and Simec International 5 divested assets and liabilities to Simec Steel, Inc., a new wholly owned subsidiary organized under the laws of the State of California whose purpose is to provide financing to the Mexican companies of the group and to seek new investment opportunities.

On May 31, 2010 Arrendadora Simec, S.A. de C.V. divested assets, liabilities and equity to our subsidiary Corporacion ASL, S. A. de C.V. which assumed the operation of Arrendadora Simec, S.A. de C.V.

On June 28, 2010, our subsidiary Simec International 6, S.A. de C.V., whose purpose is to produce steel, was constituted. Simec International 6, S.A. de C.V. begun operations in November of 2010.

On June 30, 2010, Simec International, S.A. de C.V., divested assets and equity to our subsidiary Simec International 7, S.A. de C.V. Among the assets transferred the shares of Aceros DM were included.

On September 3, 2010 we formed a Brazilian entity denominated GV do Brazil Indústria e Comércio de Aço Ltda. On august 5, 2011 we acquired 1,300,000 square meters of land on Pindamonhangaba, São Paulo State, Brazil, and paid Ps. 121.1 million (U.S.$8 million) for the construction of a new steel facility. In November 2015, our steel plant in Brazil started operations. This facility has a production capacity of 450,000 tons of finished goods of rebar and wire, and 800 employees. We have already established contact with major local suppliers of raw materials. The next step is to attract the special steels market for the automotive and electro-welded wire derivatives products.

On October 21, 2010 in the Extraordinary Shareholders Meeting of Arrendadora Simec S.A. de C.V. the dissolution of the company was approved.

On November 2, 2010, we acquired 100% of the shares of Lipa Capital, LLC. The total cost of this acquisition was of Ps. 187 million (U.S.$15.2 million at the exchange rate at that time). On December 9, 2010, Lipa Capital, LLC merged to Simec International 6, S. A. de C. V.

On February 3, 2011, we, through two of our wholly owned subsidiaries (Solon Wire Processing LLC, and the newly formed Republic Memphis LLC), acquired certain plants, machinery and equipment from BCS Industries LLC and affiliates (“Bluff City

27 

Steel”), which was our customer and vendor. For these assets we paid Ps. 30.6 million (U.S.$2.5 million) in cash and forgave approximately Ps. 73.5 million (U.S.$6 million due) by Bluff City Steel to us.

On May 2, 2011 in an Extraordinary Shareholders Meetings of Acero Transportes S.A. de C.V. and Acero Transportes San S.A. de C.V. (subsidiaries of Grupo San), their merger was authorized, whereby Acero Transportes S.A. de C.V. was merged into Acero Transportes San S.A. de C.V.

On May 20 and October 3, 2011 in Extraordinary Shareholders Meetings, Simec International 2, S.A. de C.V., Simec International 3 S.A. de C.V., Simec International 4 S.A. de C.V. and Simec International 5 S.A. de C.V., changed their address, nationality and tax authority to report to the State of California, USA, transforming them into incorporated companies in accordance with the laws and regulations of the State of California, USA.

On May 31, 2011 we sold our shares in Arrendadora del Norte de Matamoros S.A. de C.V. to Perfiles Comerciales Sigosa, S.A. de C.V. (subsidiary of ICH) for Ps. 42.5 thousand, paid in cash.

On September 1, 2011, the merger of Procesadora Industrial San S.A. de C.V. into Malla San S.A. de C.V. (subsidiaries of Grupo San) was authorized in their respective Extraordinary Shareholders Meetings.

On November 2011, Republic Steel, Inc. (a subsidiary of SimRep Corporation) entered into an agreement with an unrelated third-party “purchaser” for the factoring of specific accounts receivable in order to reduce the amount of working capital required to fund accounts receivable. The agreement was amended on October 26, 2016, so that any party can terminate the agreement after giving seven days’ notice. On the sale date, the purchaser advances funds equivalent to 80% of the value of receivables. The maximum amount of outstanding advances related to the assigned receivables is U.S.$30 million (Ps. 620 million). Proceeds on the transfer reflect the face value of the account minus a discount. The remaining amount between the receivable balance and the advance is held in reserve by the purchaser. Payment of the funds held in reserve, minus a discount fee are made by the purchaser within four days of receipt of payment on collection of funds related to each assigned receivable. The discount fee, which generally ranges from 1% if paid within 30 days (of the advance date) to 3.75% if paid within 90 days, is recorded as a charge to interest expense in the Consolidated Statements of Comprehensive Income. The purchaser shall have no recourse against Republic Steel, Inc. if payments are not received due to insolvency of an account debtor within 120 days of the invoice date. However, while the facility calls for the sale, assignment, transfer and conveyance of all rights, title and interests in the selected accounts receivable, the purchaser may put and charge-back any receivable not paid to the purchaser within 90 days of purchase for any reason besides insolvency of the account debtor. As collateral for the repayment of advances for receivables sold, the purchaser has a priority security interest in all accounts receivable of Republic Steel, Inc. Republic Steel, Inc. sold a face amount of Ps. 454.1 million (U.S.$23.1 million) and Ps. 501.3 million (U.S.$25.4 million) of accounts receivable to purchasers during the years ended December 31, 2018 and 2017, respectively. Discount fees incurred pursuant to this agreement were approximately Ps. 9.5 million (U.S.$0.5 million) and Ps. 9.5 million (U.S.$0.5 million) for the years ended December 31, 2018 and 2017, respectively. Of the face amount of accounts receivable sold to purchasers, Ps. 53.1 million (U.S.$2.7 million) and Ps. 37.5 million (U.S.$1.9 million) had not been collected by the purchaser at December 31, 2018 and 2017, respectively, and therefore, such amount at December 31, 2018, is subject to possible charge-back to us.

On December 30, 2011 Simec International 7, S.A. de C.V. sold to Corporación ASL S.A. de C.V. all of its shares in Corporación Aceros DM, S.A de C.V., comprising of a total of 627,305,446 shares (99.9% of the common stock) for a value of Ps. 3,200 million, comprised of a down payment of Ps. 63 million and the remaining of Ps. 3,137 million due on April 30, 2012. This transaction generated a tax loss of Ps. 7,860 million which amount under the Mexican Income Tax Law (Ley de Impuesto Sobre la Renta), may be deducted against future gains related to dispositions of securities. On January 30, 2012 Simec International 7, S.A. de C.V. filed a demand challenging the current law, which limits the deduction of this net loss related to shares sales. On September 24, 2013, the second district judge denied the shelter and protection of the federal courts against the company pursuant to Article 32, Section XVII of the Mexican Income Tax Law, arguing that constitutional guaranties were not violated. Dissatisfied with the decision, the company filed an application for review of such judgment with the Mexican Supreme Court of Justice. The Supreme Court resolved that the constitutionality of Article 32, Section XVII of the Mexican Income Tax Law was not violated arguing that the Income Tax Law does not violate the guaranties of tax fairness and proportionality under Article 31, section IV of the Mexican Constitution. As a result, tax losses of the company may only be applied against future gains related to dispositions of securities or capital gains.

In 2018, we had net sales of Ps. 35.7 billion, gross profit of Ps. 5.1 billion and net income of Ps. 3.3 billion. In 2018, approximately 26% of our consolidated sales were in our segment in the United States, approximately 57% were in our segment in Mexico and approximately 17% were in our segment in Brazil.

Business Strategy

We seek to further consolidate our position as a leading producer, processor and distributor of SBQ steel in North America and structural steel in Mexico. We also seek to expand our presence in the steel industry by identifying and pursuing growth opportunities and value enhancing initiatives. Our strategy includes:

Improving our cost structure.

We are continually working to reduce our operating cost and non-operating expenses and plan to continue to do so by reducing overhead expenses and operating costs through sharing best practices among our operating facilities and maintaining a conservative capital structure.

Focusing on high margin and value-added products.

We prioritize the production of high margin steel products over volume and utilization levels. We plan to continue to base our production decisions on achieving relatively high margins.

31 

Building on our strong customer relationships.

We intend to strengthen our long-standing customer relationships by maintaining strong customer service and proactively responding to changing customer needs.

Pursuing strategic growth opportunities.

We have successfully grown our business by acquiring, integrating and improving under-performing operations. In addition, we intend to continue to pursue acquisition opportunities that will allow for disciplined growth of our business and value creation for our shareholders. We also intend to pursue organic growth by reinvesting the cash generated by our operating activities to expand the capacity and increase the efficiency of our existing facilities.

Our Products

We produce a wide range of value-added SBQ steel, long steel and medium-sized structural steel products. In our Mexican facilities, we produce I-beams, channels, structural and commercial angles, hot rolled bars (round, square and hexagonals), flat bars, rebars, cold finished bars and wire rods. In our U.S. facilities, we produce hot rolled bars, cold finished bars, semi-finished tube rounds and other semi-finished trade products. In our Brazil facilities, we produce rebars, I-beams, channels, structrual and commercial angles. The following is a description of these products and their main uses:

● I-beams. I-beams, also known as standard beams, are “I” form steel structural sections with two equal parallel sides joined together by the center with a transversal section, forming 90º angles. We produce I-beams in our Mexican and Brazil facilities and they are mainly used by the industrial construction sector as structure supports.

● Channels. Channels, also known as U-Beams because of their “U” form, are steel structural sections with two equal parallel sides joined together by its ends with a transversal section, forming 90º angles. We produce channels in our Mexican and Brazil facilities and they are mainly used by industrial construction sector as structure supports and for stocking systems.

● Angles. Angles are two equal sided sections joined by their ends with a 90º angle, in an “L” form. We produce angles in our Mexican and Brazil facilities and they are used mainly by the construction and furniture industries as joist structures and framing systems.

● Hot rolled bars. Hot rolled bars are round, square and hexagonal steel bars that can be made of special or commodity steel. The construction, auto part and furniture industries mainly use the round and square bars. The hexagonal bars are made of special steel and are mainly used by the hand tool industry. We produce the steel sections in our Mexican and U.S. facilities.

● Flat bars. Flat bars are rectangular steel sections that can be made of special or commodity steel. We produce flat bars at our Mexican facilities. The auto part industry mainly uses special steel as springs, and the construction industry uses the commodity steel flat bars as supports.

● Rebar. Rebar is reinforced, corrugated round steel bars with sections from 0.375 to 1.5 inches in diameter, and we produced rebar in our Mexican facilities and in our Brazil facilities. Rebar is only used by the construction industry to reinforce concrete. Rebar is considered a commodity product due to its general acceptance by most consumers of industry standard specifications.

● Cold-finished bars. Cold-finished bars are round and hexagonal SBQ steel bars transformed through a diameter reduction process. This process consists of (1) reducing the cross sectional area of a bar by drawing the material through a die without any pre-heating or (2) turning or “peeling” the surface of the bar. The process changes the mechanical properties of the steel, and the finished product is accurate to size, free from scale with a bright surface finish. We produce these bars in our Mexican and U.S. facilities, primarily to supply the auto part industry.

During 2018, approximately 17.6% of our sales by volume came from the U.S. segment, with almost 100% of such sales representing SBQ product and 19.7% of our sales by volume came from the Brazil segment. The Mexican segment represents approximately 62.7% of our sales by volume, with SBQ products representing approximately 23% of such sales and the remainder representing commercial steel products.

Approximately 75% of our sales in the United States and Canadian markets came from contractual long-term agreements that establish minimum quantities and prices, which are adjustable based on fluctuations of prices of key production materials. The remainder of our sales in the United States and Canadian markets were spot sales either directly to end customers through our sales force or through independent distributors. We sell to customers in the United States and Canadian markets through a staff of professional sales representatives and sales technicians located in the major manufacturing centers of the Midwest, Great Lakes and Southeast regions of the United States.

We sell to the Mexican market through a group of approximately 100 independent distributors, who also carry other steel companies’ product lines, and through our wholly-owned distribution center in Guadalajara. Our sales force and distribution center are an important source of information concerning customer needs and market developments. By working through our distributors, we believe that we have established and can maintain market leadership with small-and mid-market end-users throughout Mexico. We believe that our domestic customers are highly service-conscious.

We distribute our exports outside North America primarily through independent distributors who also carry other product lines.

During 2018 and 2017, we received orders for our products in our Mexican facilities on average approximately two weeks before producing those products. We generally filled orders for our U.S. and Canadian SBQ steel products within one to 12 weeks of the order depending on the product, customer needs and other production requirements. Customer orders are generally cancelable without penalty prior to finishing size rolling and depending on customers’ changing production schedules. Accordingly, we do not believe that backlog is a significant factor in our business. A substantial portion of our production is ordered by our customers prior to production. We cannot assure you that significant levels of preproduction sales orders will continue.

In our Republic plants, we have long term relationships with most of our major customers, in some cases for 10 to 20 years or longer. Our major direct and indirect customers include: leading automotive and industrial equipment manufacturers General Motors Corporation, Ford Motor Company, Chrysler LLC, Honda of America Mfg, Inc. and Nissan North America, Inc.; first tier suppliers to automotive and industrial equipment manufacturers such as American Axle & Manufacturing Holdings, Inc. and Nexteer, NSK and NTN Driveshafts, Inc.; service centers which include AM Castle & Co., Earle M. Jorgensen Co., and Eaton Steel Bar Company.

Our U.S. facilities are strategically located to serve the majority of consumers of SBQ products in the United States. Our U.S. facilities ship products between their mills and finished products to customers by rail and truck. Customer needs and location, determine the type of transportation used for deliveries. The proximity of our rolling mills and cold finishing plants to our U.S. customers allows us to provide competitive rail and truck freight rates and flexible deliveries in order to satisfy just-in-time and other customer manufacturing requirements. We believe that the ability to meet the product delivery requirements of our customers in a timely and flexible fashion is a key to attracting and retaining customers as more SBQ product consumers reduce their in-plant raw material inventory. We optimize freight costs by using our significantly greater scale of operations to maintain favorable transportation arrangements, continuing to combine orders in shipments whenever possible and “backhauling” scrap and other raw materials.

Our plant in Brazil began production in June 2015 with 30,000 tons produced and 4,000 tons shipped in 2015, all of which correspond to rebar. Our main objective is to sell our products through independent distributors, targeting the construction market by providing quality service, a key factor in attracting and retaining customers.

Notwithstanding, our sales policy in Brazil has been well accepted by our customers and, even in the midst of a global crisis, our sales have begun to increase steadily, opening us a place in the steel market in Brazil.

Our major customers in 2018 include: Marson Com, Udiaco Comercio and Ind. ACOS Sao Carlos Come, Comercial Litoranea, RDG Acos do Brasil, Fertel Comercial Ltda, JR Comercio de Cimento e Concreto Ltda., Lorenfer Ind. and Com. From prod. Metalurgicos Ltda.

In order to grow our position in the Brazilian market, we acquired a plant from ArcelorMittal Brazil and leased a rolling mill plant in May 2018. We expect an increase in sales which will consolidate our position in the Brazilian market as a result of these acquisitions.

Competition

Competition in the steel industry is significant. Competition in the steel industry exerts a downward pressure on prices, and, due to high start-up costs, the economics of operating a steel mill on a continuous basis may encourage mill operators to establish and maintain high levels of output even in times of low demand, which further decreases prices and profit margins. The recent trend of consolidation in the global steel industry may further increase competitive pressures on independent producers of our size, particularly if large steel producers formed through consolidations, which have access to greater resources than us, adopt predatory pricing strategies that decrease prices and profit margins. If we are unable to remain competitive with these producers, our profitability and market share would likely be materially and adversely affected.

A number of our competitors in the United States, Mexico and Brazil have undertaken modernization and expansion plans, including the installation of production facilities and manufacturing capacity for certain products that compete with our products. As these producers become more efficient, we will face increased competition from them and may experience a loss of market share. In each of Mexico, Brazil and the United States we also face competition from international steel producers. Increased international competition, especially when combined with excess production capacity, would likely force us to lower our prices or to offer increased services at a higher cost to us, which could materially reduce our profit margins.

Mexico

We compete in the Mexican domestic market and in its export markets for non-flat steel products primarily on the basis of price and product quality. In addition, we compete in the domestic market based upon our responsiveness to customer delivery requirements. The flexibility of our production facilities allows us to respond quickly to the demand for our products. We also believe that the geographic locations of our various facilities throughout Mexico and variety of products help us to maintain our competitive market position in Mexico and in the southwestern United States. We believe that our Mexicali mini-mill, one of the closest mini-mills to the southern California market, is competitive in terms of production and transportation costs in northwestern Mexico and southern California.

We believe that our competitors’ closest plants to the southern California market are: Nucor, Corporation, located in Plymouth, Utah; Commercial Metals Company, located in Meza, Arizona; Thyssenkrupp Steel North America, Inc., located in Santa Fe Springs, California; Deacero, S.A. de C.V. (“Deacero”), located in Saltillo, Coahuila, México and Gerdau Corsa, S.A.P.I. de C.V. (“Gerdau Corsa”), located in Tijuana, Baja California, Mexico. We believe that we have an advantage over certain competitors due to the labor cost in our Mexican operations.

In 2018, we sold approximately 173,764 tons of I-beams, channels and angles at least three inches in width which represented approximately 7.9% of our total finished product sales for the year. In 2017, we sold approximately 179,483 tons of I-beams, channels and angles at least three inches in width which represented approximately 8.6% of our total finished product sales for the year. We believe that the domestic competitors in the Mexican market for structural steel are Gerdau Corsa, Deacero, and Siderúrgica del Golfo, S.A. de C.V. (a wholly-owned subsidiary of Industrias CH). We estimate that our share of Mexican production of structural steel was 16.8% in 2018 and 20.6% in 2017, according to information provided by the Cámara Nacional de la Industria del Hierro y del Acero (CANACERO).

In 2018, we sold approximately 834,489 tons of hot rolled and cold finished steel bars and 859,427 tons in 2017. Our other major product lines are rebar and light structural steel (angles less than three inches in width and flat bar), for which our share of domestic production was 15.3% and 19.7%, respectively, in 2018 and 14% and 21%, respectively, in 2017. Rebar and light structural steel together accounted for approximately 1,080,012 tons, or 49%, of our total production of finished steel products in Mexico, the United States and Brazil in 2018. Rebar and light structural steel together accounted for approximately 963,802 tons, or 46%, of our total production of finished steel products in Mexico, the United States and Brazil in 2017. We compete in the Mexican market with a number of producers of these products, including Deacero, Talleres y Aceros, S.A., Grupo Acerero, S.A. de C.V., Nucor Corporation, ArcelorMittal Lazaro Cardenas, S.A. de C.V., Ternium Mexico, S.A. de C.V. and Gerdau Corsa.

We believe that we have been able to maintain our domestic market share and profitable pricing levels in Mexico in part because the central Mexico sites of the Guadalajara, Apizaco, Cholula and San Luis facilities afford us cost advantages relative to certain U.S. producers when shipping to customers in central and southern Mexico, and our flexible production facility has given us the ability to ship specialty products in relatively small quantities with short lead times. The Mexicali mini-mill has helped to increase sales in northwestern Mexico and the southwestern United States because its proximity to these areas reduces our freight costs.

United States

In the United States, we compete primarily with both domestic SBQ steel producers and importers. Our U.S. domestic competition for hot-rolled engineered bar products is both large U.S. domestic steelmakers and specialized mini-mills. Non-U.S. competition may impact segments of the SBQ market, particularly where certifications are not required, and during periods when the U.S. dollar is strong compared with foreign currencies.

35 

The principal areas of competition in our markets are product quality and range, delivery reliability, service and price. Special chemistry and precise processing requirements characterize SBQ steel products. Maintaining high standards of product quality, while keeping production costs low, is essential to our ability to compete in our markets. The ability of a manufacturer to respond quickly to customer orders currently is, and is expected to remain, important as customers continue to reduce their in-plant raw material inventory.

We believe our principal competitors in the United States market, depending on the product, include Nucor, Corporation, Niagara LaSalle, Corporation, Charter Steel, Inc., Steel Dynamics, Inc., The TimkenSteel Corporation and Gerdau.

Brazil

Our main competitors in the Brazilian market are Aperam, ArcelorMittal Brazil, CSN, Gerdau, Sinobras, Thyssenkrupp CSA; Usiminas, VSB tubes, V & M do Brasil and Villares Metals.

The Brazilian steel industry is comprised of 14 private companies, controlled by 11 business groups and operating 30 mills in 10 Brazilian states, making Brazil the 8th largest producer in the world.

The privatization of steel companies, finalized in 1993, brought a significant flow of capital into the sector, with diverse shareholder composition. Thus, many steel companies came to be part of industrial and/or financial groups, with their interests in steelmaking unfolding into related activities, aiming to improved economies of scale and competitiveness.

Plants in Sao Paulo: 

● Gerdau Aços Especiais (Usina Pindamonhangaba)

● Gerdau Aços Especiais (Usina Mogi das Cruzes)

● ArcelorMittal Aços Longos (Piracicaba)

● Usiminas (Cubatão)

● Gerdau Aços Longos (Usina São Paulo)

● Gerdau Aços Longos (Usina Araçariguama)

● Villares Metals

● Simec Aços Barra (Usina Pindamonhangaba) (property of Grupo Simec)

In 2017 there was a merger between Votorantim Aço and ArcelorMittal Brazil. The Brazilian unit of ArcelorMittal has concluded the takeover of rival Votorantim Siderurgia SA in the second quarter of 2018 to become the country’s largest long steel producer, with a capacity in Brazil of up to 6 million tons per year.

Certifications

ISO is a worldwide federation of national standards bodies which have united to develop internationally accepted standards so that customers and manufacturers have a system in place to provide a product of known quality and standards. The standards set by ISO cover every aspect of quality from management responsibility to service and delivery. We believe that adhering to the stringent ISO procedures not only creates efficiency in manufacturing operations, but also positions us to meet the strict standards that our customers require. We are engaged in a total quality program designed to improve customer service, overall personnel qualifications and team work. The facilities at Apizaco and Cholula have received ISO/TS 16949:2009 certification from International Quality Certifications the current certification is effective until August 31, 2021

 As of April 15, 2019, all of Republic Steel’s plants are certified to ISO9001:2015 and IATF16949:2016. In the case of our plants in Canton, Ohio, Lackawanna, New York, and Massillon, Ohio, all are certified to IATF16949, effective until February 2021. The plant in Solon, Ohio, is certified to ISO 9001:2015, and the current certification is effective until January 2021. The ISO/TS

36 

16949:2009 standard, developed by the International Automotive Task Force, is the result of the harmonization of the supplier quality requirements of vehicle manufacturers worldwide and provides for a single quality management system of continuous improvement, defect prevention and reduction of variation and waste in the supply chain. It places greater emphasis on management’s commitment to quality and customer focus. ISO 9001 is a set of international quality control standards for management and practices.

Through these certifications, Republic’s Environmental, Health & Safety Management System is structured upon training, communication, employee participation, document control, objective and target setting, and management’s periodic reviews to implement our commitments to environmental protection and providing a safe and clean workplace.

Raw Materials

Prices for raw materials necessary for production of our steel products have fluctuated significantly in the past and significant increases in raw material prices could adversely affect our profit margins. During periods when prices for scrap metal, iron ore, ferroalloys, coaking coal and other raw materials have increased, our industry has historically sought to maintain profit margins by passing along increased raw materials costs to customers by means of price increases. For example, prices of scrap metal increased approximately 7% in 2014, decreased approximately 16% in 2015, increased approximately 2% in 2016, increased approximately 30.8% in 2017, and increased approximately 19.4% in 2018 and prices of ferroalloys increased approximately 16% in 2014, decreased approximately 9% in 2015, decreased approximately 13% in 2016, increased approximately 22% in 2017 and increased approximately 9.7% in 2018. We may not be able to pass along these and other cost increases in the future and, therefore, our profitability may be materially and adversely affected. Even when we can successfully increase our prices, interim reductions in profit margins frequently occur due to a time lag between the increase in raw material prices and the market acceptance of higher selling prices for finished steel products. We cannot assure you that our customers will agree to pay increased prices for our steel products that compensate us for increases in our raw material costs.

We purchase our raw material requirements either in the open market or from certain key suppliers. We cannot assure you that we will be able to continue to find suppliers of these raw materials in the open market, that the prices of these materials will not increase or that the quality will remain the same. In addition, if any of our key suppliers fails to deliver or we fail to renew our supply contracts, we could face limited access to some raw materials, or higher costs and delays resulting from the need to obtain our raw materials requirements from other suppliers.

In 2018, our cost of sales in Mexico, as a percentage of sales in Mexico, was 77%, compared to our U.S. operations where our cost of sales, as a percentage of sales in the United States, was 101%, as a percentage of sales in Brazil, was 94% and our consolidated cost of sales, as a percentage of consolidated sales, was 86%. The higher cost of sales of Republic facilities is mainly a result of higher labor costs prevailing in our U.S. operations, and the higher costs of the raw materials that our U.S. operations use in the production of SBQ steel.

Scrap metal, electricity, ferroalloys, electrodes and refractory products are the principal materials that we use to manufacture our steel products.

Scrap metal. Scrap metal is among the most important components for our steel production and accounted for approximately 56% of our consolidated manufacturing conversion cost in 2018 (64% of the manufacturing conversion cost in our Mexico operations, 40% of the manufacturing conversion cost in our U.S. operations and 61% in our Brazil operations), compared to 59% of our consolidated manufacturing conversion cost in 2017 (64% of the manufacturing conversion cost in our Mexico operations, 47% of the manufacturing conversion cost in our U.S. operations and 60% in our Brazil operations). Scrap metal is principally generated from automobile, industrial, naval and railroad industries. The market for scrap metal is influenced by availability, freight costs, speculation by scrap brokers and other conditions largely beyond our control. Fluctuations in scrap costs directly influence the cost of sales of finished goods.

We purchase raw scrap from dealers in Mexico and the San Diego area, and we process the raw scrap into refined scrap metal at our Guadalajara, San Luis, Mexicali and Apizaco facilities. We meet our refined scrap metal requirements through: (i) our wholly-owned scrap processing facilities, which in the aggregate provided us with approximately 21% and 19.1% of our refined scrap tonnage in 2018 and 2017, respectively, and (ii) purchases from third party scrap processors in Mexico and the southwestern United States, which, in the aggregate, provided us with approximately 74.9% and 4.1%, respectively, in 2018 and approximately 72.2% and 8.7%, respectively, in 2017 of our refined scrap metal requirements. We are a large scrap collector in the Mexicali, Tijuana and Hermosillo regions, and, by primarily dealing directly with small Mexican scrap collectors, we believe we have been able to purchase scrap at prices lower than those in the international and Mexican markets. We purchase scrap on the open market through a number of brokers or directly from scrap dealers for our U.S. facilities. We purchase scrap on the open market through a number of brokers or directly from scrap dealers for our Brazil facilities. We do not depend on any single scrap supplier to meet our scrap requirements.

Ferroalloys, Electrodes and Refractory Products. In our Mexican operations, ferroalloys, electrodes and refractory products collectively accounted for approximately 16% of our manufacturing conversion cost in 2018, compared to 13% in 2017, in our U.S. and Canadian facilities accounted for 17% of our manufacturing conversion cost in 2018, compared to 16% in 2017 and in our Brazil facilities accounted for approximately 14% of our manufacturing conversion cost in 2018 compared to 13% in 2017.

Ferroalloys are essential for the production of steel and are added to the steel during manufacturing process to reduce undesirable elements and to enhance its hardness, durability and resistance to friction and abrasion. For our Mexican operations, we buy most of our manganese ferroalloys from Compañía Minera Autlán, S.A., Elmet, S.A. de C.V., Autlán Metal Services, S.A. de C.V., Marco Metales de Mexico, S. de R.L. de C.V., Possehl México, S.A. de C.V. and Distribuidora de Aleaciones y Metales, S.A. de C.V. Our U.S. facilities purchase most of their ferroalloys from Affival, Duferco Steel, Globe Met., Gottlieb, Kennecott, Rusian Ferro, Traxys, Vale Americas, Minerais U.S. LLC and Glencore LTD. Our Brazil facilities purchase most of their ferroalloys from Multiligas Eireli., Comercial Cometa Industria y Comercio Ltda., Fertiligas Industria e Comércio Ltda., Cia. de Ferroligas de Bahia Ferbasa, Bozel Brasi, S.A., Fertileg Ferro Liga Ltda, Granhas Ligas Ltda., Cia. De Ferro Ligas da Bahia Ferbasa and Cia. Brasileira de Matalurgia e Mineracao.

For our Mexican operations, we obtain electrodes used to melt raw materials (scrap metal) from Dura Carbon Singapore Private Limited, Sinosteel Jilin Carbon Co. Ltd., Starex Inc., Cimm Carbon Group, Heg Limited and Graphite Cova GmbH. Our U.S. facilities purchase most of their electrodes from SGL Carbon, Showa Denko Carbon, SK Carbon and E. J. Bognar Inc. Our Brazil facilities purchase most of their electrodes from Starex, Inc., Ray Group Limited, Cimm Carbon Group, Dura Carbon Singapore Private Limited, Jilin Carbon Co. Ltd., Baystar, Daliane and Graftech Comercial de Mexico, S.A.

Refractory products include firebricks, which line and insulate furnaces, ladles and other transfer vessels. We purchase our refractory products for our Mexican operations from Vesuvius de México, S.A. de C.V., Magnesita Refractories México, S.A. de C.V., Magna Refractarios México, S.A. de C.V. and Refratechnik Steel GmbH. Our U.S. facilities purchase most of their refractory products from RHI Inc, Vesuvius USA, Corp., Nock & Son Co.-Minteq, Magna Refractories Inc., Refractory Materials Intl., Altus Refractories, LLC, Thermatex Sales Corp., Harbison-Walker Refractories Company and Magnesita Refractories Co. Our Brazil facilities purchase most of their refractory products from Magnesitas Navarrasm S.A., Vesivius, Samboba and Magnesita Refractaries Mexico S.A. de C.V.

Electricity. In 2018 and 2017 electricity accounted for approximately 9% and 9% respectively, of our consolidated manufacturing conversion cost. Electricity accounted for 9% in 2018 of our manufacturing conversion cost and 9% in 2017 in our Mexico facilities and is supplied by the Comisión Federal de Electricidad (CFE). It accounted for 8% in 2018 and 8% in 2017 of the manufacturing conversion cost in our U.S. operations and is supplied by American Electric Power Company, Nipsco Industries, Inc., New York Power and Ohio Edison. It accounted for 9% in 2018 and 15% in 2017 of the manufacturing conversion cost in our Brazil operations and is supplied by Ecom Energia Ltda. and Comercializadora de Energiaeletrica Ltda. We, like most high volume users of electricity in Mexico, pay special rates to CFE for electricity. Energy prices in Mexico have historically been very volatile and subject to dramatic price increases in short periods of time. In the late 1990s, the CFE began to charge for electricity usage based on the time of use during the day and the season (summer or winter). As a result, we have modified our production schedule in order to reduce electricity costs by limiting production during periods when peak rates are in effect. We cannot assure that any future cost increases will not have a material adverse effect on our business.

Natural Gas. Natural gas (including “combustoleo” fuel oil which is an oil derivative that is less refined than gasoline and diesel fuel oil that can be used instead of gasoline in our Mexicali plant) consisted of approximately 3% of our consolidated manufacturing conversion cost (2% of the manufacturing conversion cost of our Mexican operations, 3% of the manufacturing conversion cost of our U.S. operations and 3% of our Brazil operations) in 2018 and approximately 3% of our consolidated manufacturing conversion cost (2% of the manufacturing conversion cost of our Mexican operations, 3% of the manufacturing conversion cost of our U.S. operations and 3% of our Brazil operations) in 2017. In previous years we have entered into natural gas cash-flow exchange contracts or swaps where we receive a floating price and pay a fixed price to hedge our risk of from fluctuations in natural gas prices. Fluctuations in natural gas prices from volume consumed are recognized as part of our operating costs. As applicable, we recognized the fair value of instruments either as liabilities or assets. We periodically evaluated the changes in the cash flows of derivative instruments to analyze if the swaps are highly effective for mitigating the exposure to natural gas price fluctuations. At December 31, 2018 and 2017 we did not have natural gas cash-flow exchange contracts or swaps. For the derivatives that qualified for hedge accounting, their fair value was adjusted through the stockholders’ equity under the caption fair value of derivative financial instruments until such time as the related item in the derivative hedges is recognized as income.

We do not enter into contracts for speculation purposes.

Regulation

U.S. Operations

Our U. S. operations are subject to U.S. federal, state and local environmental laws and administrative regulations concerning, among other things the management of hazardous materials and the discharge of pollutants to the atmosphere and to surface waters. Our U.S. operations have been the subject of administrative action by federal, state (or provincial) and local environmental authorities. The resolution of any of these claims may result in significant liabilities. See Item 3.D. “Risk Factors—Risk Factors Related to our Business—In the event of environmental violations at our facilities we may incur significant liabilities” and Item 8. “Financial Information—Legal Proceedings.”

Environmental Matters

We are subject to a broad range of environmental laws and regulations, including those governing the following:

● discharges to the air, water and soil;

● the handling and disposal of solid and hazardous wastes;

● the release of petroleum products, hazardous substances, hazardous wastes, or toxic substances to the environment; and

● the investigation and remediation of contaminated soil, sediment and groundwater.

We monitor our compliance with these laws and regulations through our environmental management system, and believe that we currently are in substantial compliance with them, although we cannot assure you that we will at all times operate in compliance with all such laws and regulations. If we fail to comply with these laws and regulations, we may be assessed fines or penalties or be subject to injunctive relief which could have a material adverse effect on us.

Future changes in the applicable environmental laws and regulations, or changes in the regulating agencies’ approach to enforcement or interpretation of their regulations, could cause us to make additional capital expenditures beyond what we currently anticipate.

Our Lorain, Ohio plant (which is not currently in operation) and our Canton, Ohio facility are subject to the Maximum Achievable Control Technology (“MACT”) standard for Electric Arc Furnaces as an “area source.” Revisions of this standard are under development and, when promulgated, may impose additional restrictions on our Lorain and Canton operations including those relating to mercury emissions and control.

Our steelmaking operations in the United States and in Mexico use electric arc furnaces where carbon dioxide generation is primarily linked to energy use. In the United States, the federal environmental agency has issued rules imposing inventory and reporting obligations to which some of our facilities are subject, and has also issued rules that will affect preconstruction permits for our facilities where increases in greenhouse gas pollutants are contemplated. The U.S. Congress has debated various measures for regulating greenhouse gas emission (such as carbon dioxide) and may enact them in the future. Such laws and regulations may also result in higher costs for coking coal, natural gas and electricity generated by carbon-based systems (such as coal-fired electric generating facilities). Such future laws and regulations, whether in the form of cap-and-trade emissions permit system, a carbon tax or other regulatory regime may have a negative effect on our operations. Climate change policy is evolving at regional, national and international levels, and political and economic events may significantly affect the scope and timing of climate change measures that are ultimately put in place. As signatories to the UNFCCC, Mexico and the U.S. became subject to the Paris Agreement to fight climate change, which was taken by the parties at the 21th session of the UNFCCC conference of the Parties in 2015. However, in June 2017, U.S. President Trump stated that the United States would withdraw from the Paris Agreement, but may enter into a future international agreement related to greenhouse gas emissions. In August 2017, the U.S. State Department officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The United States’ adherence to the exit process is uncertain and/or the terms on which the United States may reenter the Paris Agreement or a separately negotiated

agreement are unclear at this time. As a result, some of our significant facilities may ultimately be subject to future regional, provincial and/or federal climate change regulations to manage greenhouse emissions. More stringent greenhouse policies and regulations could adversely affect our business and results of operations.

Various federal, state (or provincial) and local laws, regulations and ordinances govern the removal, encapsulation or disturbance of asbestos-containing materials (“ACMs”). These laws, regulations and ordinances may impose liability for the release of ACMs and may permit third parties to seek recovery from owners or operators of facilities at which ACMs were or are located for

39 

personal injury associated with exposure to ACMs. We are aware of the presence of ACMs at our facilities but we currently believe that such materials are being managed in accordance with applicable law.

In the United States, the federal environmental protection agency is developing a new rule that is expected, among other things, to impose a timeline for the phasing out of polychlorinated biphenyl (“PCB”) -containing fluid in equipment that we currently use at many of our U.S. facilities. A preliminary notice regarding this future regulation was published in 2016 for comments, and a formal proposed rule is expected within the next two years. If the rule is enacted as proposed, it will require our facilities to reduce the levels of PCBs in our equipment to less than 50 ppm within 5 years following its adoption, which will in turn require us to incur cost for the removal and disposal of PCB containing oils, sampling and possible replacement of equipment in the event PCB levels cannot be reduced to acceptable levels.

Also in the United States, more stringent standards for particulate matter were promulgated in 2012. As these new more stringent standards were implemented through the different state programs, we experienced higher costs associated with any preconstruction permitting of new or modified sources at our U.S. facilities in 2014 and subsequent years. These costs were related to extensive dispersion modeling and/or pre-construction monitoring not previously required.

Mexican Operations

We are subject to Mexican federal, state and municipal laws, administrative regulations and Mexican Official Rules (Normas Oficiales Mexicanas) relating to a variety of environmental matters, anti-trust matters, trade regulations, and tax and employee matters.

Among other matters, Mexican tax returns are open for review generally for a period of five years, and, according to Mexican tax law, the purchaser of a business may become jointly and severally liable for unpaid tax liabilities of the business prior to its acquisition, which may have an impact on the liabilities and contingencies derived from any such acquisitions. Although we believe that we are in compliance with all material Mexican federal, state and municipal laws, administrative regulations and Mexican Official Rules, we cannot assure you that the interpretation of the Mexican authorities of the laws and regulations affecting our business or the enforcement thereof will not change in a manner that could increase our costs of doing business or could have a material adverse effect on our business, results of operations, financial condition or prospects.

Environmental Matters

We are subject to various Mexican federal, state and municipal laws, administrative regulations and Mexican Official Rules (Normas Oficiales Mexicanas) relating to the protection of human health, the environment and natural resources.

The major federal environmental laws applicable to our operations, among others, are: (i) the General Law of Ecological Balance and Environmental Protection (Ley General del Equilibrio Ecológico y la Protección al Ambiente or “LGEEPA”) and its regulations, which are administered and overseen by the Ministry of the Environment and Natural Resources (Secretaría de Medio Ambiente y Recursos Naturales or “SEMARNAT”) and enforced by the Ministry’s enforcement branch, the Federal Attorney’s Office for the Protection of the Environment (Procuraduría Federal de Protección al Ambiente or “PROFEPA”); (ii) the General Law for the Prevention and Integral Management of Waste (Ley General para la Prevención y Gestión Integral de los Residuos or the “Law on Wastes”), which is also administered by SEMARNAT and enforced by PROFEPA; (iii) the National Waters Law (Ley de Aguas Nacionales) and its regulations, which are administered and enforced by the National Waters Commission (Comisión Nacional de Agua), also a branch of SEMARNAT; and (iv) the Federal Law on Environmental Responsibility (Ley Federal de Responsabilidad Ambiental), which is also administered by SEMARNAT and enforced by PROFEPA.

In addition to the foregoing, Mexican Official Rules, which are technical standards issued by applicable regulatory authorities pursuant to the General Normalization Law (Ley General de Metrología y Normalización) and to other laws that include the environmental laws described above, establish standards relating to air emissions, waste water discharges, the generation, handling and disposal of hazardous wastes and noise control, among others. Mexican Official Rules regarding soil contamination and waste management were enacted in order to protect these potential contingencies. Although not enforceable, the internal administrative criteria on soil contamination established by PROFEPA is widely used as guidance in cases where soil remediation, restoration or clean-up is required.

LGEEPA sets forth the legal framework applicable to the generation and handling of hazardous wastes and materials, the release of contaminants into the air, soil and water, as well as the environmental impact assessment of the construction, development and operation of different projects, sites, facilities and industrial plants similar to the ones owned and/or operated by us and our subsidiaries. In addition to LGEEPA, the Law on Wastes regulates the generation, handling, transportation, storage and final disposal of hazardous waste.

40 

LGEEPA also mandates that companies that contaminate soil be responsible for the clean-up. Furthermore, the Law on Wastes provides that owners and lessors of real property with soil contamination are jointly and severally liable for the remediation of such contaminated sites, irrespective of any recourse or other actions such owners and lessors may have against the contaminating party, and aside from the criminal or administrative liability to which the contaminating party may be subject. The Law on Wastes also restricts the transfer of contaminated sites.

PROFEPA can bring administrative, civil and criminal proceedings against companies that violate environmental laws, regulations and Mexican Official Rules, and has the power to impose a variety of sanctions. These sanctions may include, among others, monetary fines, revocation of authorizations, concessions, licenses, permits or registries, administrative arrests, seizure of contaminating equipment, and in certain cases, temporary or permanent closure of facilities.

Additionally, as part of its inspection authority, PROFEPA is entitled to periodically visit the facilities of companies whose activities are regulated by Mexican environmental legislation, and verify compliance. Similar rights are granted to state environmental authorities pursuant to applicable state environmental laws.

Companies in Mexico are required to obtain proper authorizations, concessions, licenses, permits and registries from competent environmental authorities for the performance of activities that may have an impact on the environment or may constitute a source of contamination. Such companies in Mexico are also required to comply with a variety of reporting obligations that include, among others, providing PROFEPA and SEMARNAT with periodic reports regarding compliance with various environmental laws. Among other permits, the operations and related activities of the steel industry are subject to the prior obtainment of an environmental impact authorization granted by SEMARNAT.

We believe that we have obtained all the necessary authorizations, concessions, general operating licenses, permits and registries from the applicable environmental authorities to duly operate our facilities, plants and sites, and sell our products and that we are in material compliance with applicable environmental legislation. We, through our subsidiaries, have made significant capital investments to assure our production and operation facilities comply with requirements of federal, state and municipal law and administrative regulation, and to remain in compliance with our current authorizations, concessions, licenses, permits and registries.

We cannot assure you that in the future, we and our subsidiaries will not be subject to stricter Mexican federal, state or municipal environmental laws and administrative regulations, or more stringent interpretation or enforcement of existing laws and administrative regulations. Mexican environmental laws and administrative regulations have become increasingly stringent over the last decade, and this trend is likely to continue, influenced recently by the North American Agreement on Environmental Cooperation entered into by Mexico, the United States and Canada in connection with the NAFTA or the USMCA. Further, we cannot assure you that we will not be required to devote significant expenditures to environmental matters, including remediation-related matters. In this regard, any obligation to remedy environmental damages caused by us or any contaminated sites owned or leased by us could require significant unplanned capital expenditures and be materially adverse to our financial condition and results of operations.

In Mexico, the National Waters Law regulates water resources. In addition, the Mexican Official Rules govern the quality of water. A concession granted by the National Waters Commission is required for the use and exploitation of national waters. Some of our facilities in Mexico have a renewable concession to use and exploit underground waters from wells in order to meet the water requirements of our production processes. We pay the National Waters Commission duties per cubic meter of water extracted under our concessions. We believe we are in substantial compliance with all the requirements imposed by each of the concessions we have obtained.

Pursuant to the National Waters Law, companies that discharge waste into national water bodies must comply with certain requirements, including maximum permissible contamination or pollution levels. Periodic reports on water quality must be provided by dischargers to applicable authorities. Liability may result from the contamination of underground waters or recipient water bodies. We believe that we are in substantial compliance with all water and waste water legislation applicable to us.

Antitrust Matters

We are also subject to the Mexican Antitrust Law (Ley Federal de Competencia Económica), which regulates monopolies and monopolistic practices in Mexico and requires Mexican government approval of certain mergers, acquisitions and joint ventures. We believe that we are currently in material compliance with the Mexican Antitrust Law. However, due to our growth strategy of acquiring new businesses and assets and because we are a large manufacturer with a significant share of the markets in Mexico with respect to certain of our products, we may be subject to greater regulatory scrutiny in the future.

Measurements Law

Mexico’s Ministry of Economy (Secretaría de Economía), through the General Rules Department (Dirección General de Normas or “DGN”), promulgates regulations regarding many products that we manufacture. Specifically, pursuant to the Measurements Law (Ley Federal sobre Metrología y Normalización), the DGN issues specifications on the quality and safety standards for our product lines. We believe that all of our products are in material compliance with all applicable DGN regulations.

Trade Regulation Matters

We have experienced significant competition from imports into Mexico in the past as a result of excess worldwide steel production capacity, particularly in periods of economic slowdown, and as a consequence of the Peso’s appreciation, making imports cheaper and more competitive in peso terms. In 2003, imports declined as international market conditions improved and the peso weakened. Recently, the Mexican government, at the request of CANACERO, has taken several measures to prevent unfair trade practices such as dumping the steel import market. The overall climate for imports in Mexico is influenced by the free trade agreements that Mexico has entered into with other countries, as well as the level of tariffs and anti-dumping duties (some of which are described below).

We have benefited from the free trade agreements that Mexico has entered into. Specifically, we have directly benefited from our ability to export finished steel products directly to export markets and compete with similar products manufactured in those markets. We have also indirectly benefited from increased demand from our domestic customers who similarly manufacture their products to foreign markets under free trade agreements. Nevertheless, we cannot assure you that the trade agreements affecting our business or the enforcement thereof will not change in a manner that could have a material adverse effect on our business, results of operations, financial condition or prospects.

North American Free Trade Agreement. NAFTA became effective on January 1, 1994. NAFTA provided for the progressive elimination over a period of ten years of the 10% duties formerly in effect on most steel products imported into Mexico from the United States and Canada, including those that compete with our main product lines. Currently there is a 25% duty for steel products being exported to the United States. Leaders from the United States, Canada and Mexico also commenced discussions regarding NAFTA on January 23, 2018 in Montreal, Canada. In November 2018, the United States, Mexico and Canada signed the United States-Mexico-Canada Agreement, or USMCA, which is designed to replace NAFTA. The USMCA remains subject to approval and ratification by the legislatures in each of the three countries. See “Item 3.D. Risk Factors—Risks Related to Mexico—Developments in other countries could adversely affect the Mexican economy, our financial performance and the price of our shares.”

Mexican-European Community Free Trade Agreement. The Mexican-European Free Trade Agreement, or “MEFTA,” became effective on July 1, 2000, and taxes applying to a large quantity of imported goods were eliminated or reduced. The goal of this trade agreement is to establish a bilateral and preferential, progressive and reciprocal framework to encourage the development of trade in goods and services, taking into account the sensitivity of certain products and services sectors, and in accordance with relevant rules of the World Trade Organization (WTO). The Joint Council is responsible for deciding the arrangements and timetable for the liberalization of duties and non-duty barriers to trade in goods, in accordance with the relevant WTO rules. This agreement was modified in 2018.

Mexico-Japan Economic Association (the “Association”). On January 1, 2004, Japan and the other members of the G-7, agreed to reduce the steel tariffs to zero percent, so Mexico has benefited from this rate since such date. However, Mexico is sensitive to the steel exports coming from Japan, so the Association was negotiated in the following terms: (i) the specialized steel that is not produced in Mexico, and that is used to produce vehicles, spare parts, electronics, machinery and heavy equipment, was released from any tariffs, as from the effective date of the Association, (ii) the steel products coming from Japan currently have a zero percent rate, (iii) the products to be imported from the under the programs established by the Association, will pay the tariffs pursuant to the fixed tariffs established in such Sector Programs, so the electronic and vehicles industries will be exempted as of the effective date of the Association.

Other Trade Agreements. In the last several years, Mexico has signed other free trade agreements with Israel (2000), Iceland, Norway, Liechtenstein and Switzerland (2001), and with the following Latin American countries: Chile (1992 and amended in 1999); Venezuela and Colombia (1995); Costa Rica (1995); Bolivia (1995); Nicaragua (1998); Honduras, El Salvador and Guatemala (2001); and Uruguay (2003). We do not anticipate any significant increase in competition in the Mexican steel market as a result of these trade agreements due to their minimal steel production or, in the case of Venezuela and Chile, minimal share of the Mexican market. Venezuela stepped off the free trade agreement with Mexico and Columbia.

Transpacific Partnership Trade Agreement (TPP). On February 4, 2016, Mexico, along with Australia, Brunei, Canada, Chile, United States, Japan, Malaysia, New Zealand, Peru, Singapore and Vietnam, signed the TPP, in the City of Auckland, New Zealand. This treaty will grant Mexican products access to six markets (Australia, Brunei, Malaysia, New Zealand, Singapore and Vietnam) with approximately 155 million of potential consumers, which were not covered by any other trade agreement. The TPP is supposed to

42 

become effective two years after its signature, provided all 12 participating countries ratify the agreement, or when at least six countries representing at least 85% of the gross domestic product of the TPP ratify the agreement.

The TPP will eliminate or reduces tariff and non-tariff barriers across substantially all trade in goods and services and covers the full spectrum of trade, including goods and services trade and investment, so as to create new opportunities and benefits for the businesses, workers, and consumers of the countries members.

The TPP will facilitate the development of production and supply chains, and seamless trade, enhancing efficiency and supporting the goal of creating and supporting jobs, raising living standards, enhancing conservation efforts, and facilitating cross-border integration, as well as opening domestic markets.

The TPP will promote innovation, productivity, and competitiveness by addressing new issues, including the development of the digital economy, and the role of state-owned enterprises in the global economy.

The TPP includes new elements that seek to ensure that economies at all levels of development and businesses of all sizes can benefit from trade. It includes commitments to help small- and medium-sized businesses understand the Agreement, take advantage of its opportunities, and bring their unique challenges to the attention of the TPP governments. It also includes specific commitments on development and trade capacity building, to ensure that all Parties are able to meet the commitments in the Agreement and take full advantage of its benefits.

The TPP is intended as a platform for regional economic integration and designed to include additional economies across the Asia-Pacific region.

The President of the United States, Donald Trump, signed an executive order on January 2017 withdrawing the United States from the TPP.

On January 23, 2018, the 11 remaining countries participating in the TPP reached an agreement in Tokyo, Japan. Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and Vietnam, member countries of the TPP, signed the agreement on March 8, 2018 in Santiago de Chile. The countries that have ratified the TPP are Mexico, Canada, Australia, Japan, New Zealand and Singapore. It is expected that in 2019, Peru, Chile, Brunei, Malaysia and Vietnam will join when their governments ratify the agreement.

Dumping and Countervailing Duties. We are or have been a party to, or have been affected by, numerous steel dumping and countervailing duty claims. Many of these claims have been brought by Mexican steel producers against international steel companies, while others have been brought against Mexican steel companies. In certain instances, such cases have resulted in duties being imposed on certain imported steel products and, in a few instances, duties have been imposed on Mexican steel exports. In the aggregate, these duties have not had a material impact on our results of operations.

On September 11, 2013, the United States International Trade Commission (USITC) started an official anti-dumping investigation against rebar exports from Mexico and Turkey promoted by Nucor, Gerdau, Commercial Metals, and Cascade Steel Byer.

● On September 25, 2013, the USITC determined that there was sufficient evidence of “injury” therefore, on October 2, 2013, the Department of Commerce (DOC) started the antidumping investigation.

● On November 21, 2013, DeAcero was named a “Mandatory Respondent” of the questionnaires and on February 12, 2014, we were named the second “Mandatory Respondent” thereby replacing Grupo Acerero, S.A. de C.V. which is not participating in the process.

● On April 21, 2014, preliminary “dumping” quotas were published: 66.7 % to Grupo Acerero, S.A. de C.V., 10.66 % to us and 20.59% to other Mexican exporters (including DeAcero).

● On October 14, 2014, the United States International Trade Commission (USITC) determined that a U.S. industry is materially injured by reason of imports of steel concrete reinforcing bar from Mexico that are sold in the United States at less than fair value and from Turkey that are subsidized by the government of Turkey. As a result of the USITC’s affirmative determinations, the U.S. Department of Commerce will issue an antidumping duty order on imports of this product from Mexico and a countervailing duty order on imports of this product from Turkey. The U.S. government imposed tariffs of 66.7% against imports for rebar from Deacero and us and tariffs of 20.58% for rebar from all other imports from producers in Mexico. On November 16, 2015, we filed a request for review with the U.S. Department of Commerce against the imposed tariffs. On December 6, 2016, the US Department of Commerce issued a preliminary

43 

resolution in which it determined that the tariff is 0%.

● On June 8, 2017, the US Department of Commerce issued a final resolution in which it determined that the tariff should become 0%, although this is currently under review by U.S. authorities.

On August 14, 2013, the Ministry of Industry and Tourism of Colombia (MIT) started an official safeguard investigation against imports of commercial angles and plates originating from countries that are members of the World Trade Organization (WTO) at the request of DIACO-GERDAU and SIDOC, seeking the imposition of a countervailing duty of 35%.

● We were the only Mexican producer that responded to the questionnaire in October 10, 2013.

● On April 2, 2014, the MIT announced at a press conference that they would not impose safeguard measures to rebar nor to profiles of steel angles, square bars / slabs / plates. Only wire was subject to safeguard measures with an antidumping duty of 21.29%.

● On May 1, 2019, the Peruvian Commission on Dumping, Subsidies and Elimination of Commercial Customs (INDECOPI ) resolved not to impose duties on Mexican and Brazilian rebar imports.

D. Property, Plants and Equipment

Our Operations and Production Facilities

We conduct our operations at 15 facilities throughout America. At December 31, 2018, our crude steel production capacity was 5.3 million tons, of which 1.2 million tons were based on an integrated blast furnace technology, and 4.1 million were based on electric arc furnace, or mini-mill, technology. Our Mexican facilities have 2.3 million tons of crude steel production capacity, operating six mini-mill facilities. Our U.S. operations have 2.1 million tons of crude steel production capacity and our Brazil operations have 0.9 million tons of crude steel production capacity. In addition, we have 4.5 million tons of rolling and finishing capacity, of which 2.1 million are located in Mexico, 1.7 million are located in the United States and Canada and 0.7 million are located in Brazil.

We operate nine mini-mills, six in Mexico, one in the United States and two in Brazil. The Mexican mini-mills are located in Guadalajara, Jalisco; two in Apizaco, Tlaxcala; Mexicali, Baja California; as well as two in San Luis Potosí. Our mini-mill in the United States is located in Canton, Ohio. Our mini-mills in Brazil are located in Pindamonhangaba, São Paulo and Cariacica, Espírito Santo. We also own an integrated blast furnace and an electric arc furnace in Lorain, Ohio and a rolling mill in Lackawanna, New York. Processing mills are located in Massillon, Ohio and Solon, Ohio.

Because we own both mini-mill and integrated blast furnace production facilities, we can allocate production between each type of facility based on efficiency and cost. In addition, as long as our facilities are not operating at full capacity, we can allocate production based on the relative cost of basic inputs (iron ore, coaking coal, scrap metal and electricity) to the facility where production costs would be the lowest. Our production facilities are designed to permit the rapid changeover from one product to another. This flexibility permits us to efficiently produce small volume orders to meet customer needs and to produce varying quantities of standard product. Production runs, or campaigns, occur on four to eight weeks cycles, minimizing customer waiting time for both standard and specialized products.

We can use scrap metal or iron ore to produce our finished steel products. We produce liquid steel using an electric arc furnace, alloying elements and carbon are added, and then is transported to continuous casters for solidification. The continuous casters produce long, square strands of steel that are cut into billet and transferred to the rolling mills for further processing or, in some cases, sold to other steel producers. In the rolling mills, the billet is reheated in a walking beam furnace with preheating burners, passed through a rolling mill for size reduction and conformed into final sections and sizes. The shapes are then cut into a variety of lengths. Our facility in Canton, Ohio is capable of producing billets and blooms.

Our mini-mill plants use an electric arc furnace to melt ferrous scrap and other metallic components, which are then cast into long, square bars called billets in a continuous casting process, all of which occurs in a melt shop. The billet is then transferred to a rolling mill, reheated and rolled into finished product. In contrast, an integrated steel mill heats iron pellets and other primary materials in a blast furnace to first produce pig iron, that must be refined in a basic oxygen furnace to liquid steel, and then cast to billet and finished product. Mini-mill plants typically produce certain steel products more efficiently because of the lower energy requirements resulting from their smaller size and because of their use of ferrous scrap. Mini-mills are designed to provide shorter production runs with relatively fast product changeover times. Integrated steel mills are more efficient in producing longer runs and are able to produce certain steel products that a mini-mill cannot.

The production levels and capacity utilization rates for our melt shops and rolling mills for the periods indicated are presented below.

Guadalajara. Our Guadalajara mini-mill facility is located in central western Mexico in the state of Jalisco which is Mexico’s second largest city. Our Guadalajara facilities and equipment include one improved electric arc furnace utilizing water-cooled sidewalls and roof, one four-strand continuous caster, five reheating furnaces and three rolling mills. The Guadalajara mini-mill has an annual installed capacity of 370,000 tons of billet and an annual installed capacity of finished product of 480,000 tons. In 2018, the Guadalajara mini-mill produced 234,827 tons of steel billet and 312,513 tons of finished product, operating at 63% capacity for billet production and 65% capacity for finished product production. The Guadalajara rolling facilities process billet production from our Mexicali and Apizaco mills. Our Guadalajara facility is 336 miles from Mexico City. Our Guadalajara facility mainly produces structurals, SBQ steel, light structurals and rebars.

Mexicali. In 1993, we began operations at our mini-mill located in Mexicali, Baja California. The mini-mill is strategically located approximately 22 miles south of the California border and approximately 220 miles from Los Angeles.

Our Mexicali facilities and equipment include one electric arc furnace utilizing water-cooled sidewalls and roof, one four-strand continuous caster, one walking beam reheating furnace, one SACK rolling mill, a Linde oxygen plant and a water treatment plant. This facility has an annual installed capacity of 430,000 tons of steel billet and an annual installed capacity of finished product of 250,000 tons. Excess billet produced at the Mexicali facility is used primarily by the Guadalajara facility. This allows us to increase the utilization of the Guadalajara facility’s finishing capacity, which exceeds its production capacity. In 2018, the Mexicali mini-mill produced approximately 271,221 tons of billet, of which the Guadalajara mini-mill used 77,308 tons. In 2018, the Mexicali mini-mill produced 199,119 tons of finished products. In 2018 we operated the Mexicali mini-mill at 63% capacity for billet production and at 80% capacity for finished product production. Our facility is strategically located and has access to key markets in Mexico and the United States, stable public sources of scrap, electricity, a highly skilled workforce and other raw materials. The Mexicali mini-mill also is situated near major highways and a railroad linking the Mexicali and Guadalajara mini-mills, allowing for coordinated production at the two facilities.

Item 4A. Unresolved Staff Comments

In the months of December 2017 and February and March 2018, the Company received written comments from the staff of the U.S. Securities and Exchange Commission (the “SEC”) regarding the Company's annual report on Form 20-F for the year ended December 31, 2016. In such comments, the staff requested further information regarding the nature and the accounting treatment of certain related party loans. The SEC continues to request that the Company voluntarily produce certain documents related to such related party loans and the Company has been and continues to cooperate with the SEC on this matter. See “Item 8. Financial Information-A. Consolidated Statements and Other Financial Information-Legal Proceedings.”

Item 5. Operating and Financial Review and Prospects

The following discussion is derived from our audited consolidated financial statements, which are presented elsewhere in this annual report. This discussion does not include all of the information included in our financial statements. You should read our financial statements to gain a better understanding of our business and our historical results of operations. All of the statements in this Item 5.A are subject to and qualified by the information set forth under the “Cautionary Statement Regarding Forward Looking Statements.”

Adoption of International Financial Reporting Standards (IFRS)

The Mexican National Banking and Securities Commission (CNBV) has established the requirement that listed companies must disclose their financial information to the public, through the Mexican Stock Exchange (BMV) or the Bolsa Institucional de Valores, S.A. de C.V. (BIVA) (operating since July 25, 2018), and therefore, beginning in 2012, we prepare our financial information in accordance with IFRS, as issued by the IASB. IFRS differs in certain significant respects from U.S. GAAP. Accordingly, Mexican financial statements and reported earnings are likely to differ from those of companies in other countries in this and other respects.

A. Operating Results

Overview

We are producers of SBQ and structural steel products. Accordingly, our net sales and profitability are highly dependent on market conditions in the steel industry which is greatly influenced by general economic conditions in North America and globally. The sharp reduction in economic activity and consumer demand in general, and in the automotive, construction and manufacturing industries in particular, in North America starting in the fourth quarter of 2008 has had a significant negative impact on the demand and price levels for all steel products, including SBQ and structural steel products. These economic conditions have had an impact on all parts of our operations since the fourth quarter of 2008. Demand, production levels and prices in certain segments and markets

52 

have recovered and stabilized to a certain degree, although the extent, timing and duration of the recovery and potential return to pre-crisis levels remains uncertain. Our net revenue from sales increased in 2014, compared to 2013, increased by 42% in the automotive sector, decreased 13% in the independent distributor sector, decreased 34% in the hand tools sector, decreased 61% in the mining sector and increased 29% in other industries. The total increase in net revenue from sales of SBQ products in 2014, compared to 2013, was 18%. Our net revenue from sales decreased in 2015, compared to 2014, increased by 20% in the automotive sector, decreased 43% in the independent distributor sector, increased 204% in the hand tools sector, decreased 52% in the mining sector and decreased 48% in other industries. The total decrease in net revenue from sales of SBQ products in 2015, compared to 2014, was 16%. Our net revenue from sales decreased in 2016, compared to 2015, decreased by 18% in the automotive sector, increased 9% in the independent distributor sector, decreased 72% in the hand tools sector, decreased 42% in the mining sector and decreased 10% in other industries. The total decrease in net revenue from sales of SBQ products in 2016, compared to 2015, was 13%. In 2017, the total increase in net revenue from sales of SBQ products compared to 2016 was 13%. In 2018, the total increase in net revenue from sales of SBQ products compared to 2017 was 10%.

As a result of the significant competition in the steel industry and the commodity-like nature of some of our products, we have limited pricing power over many of our products. The North American and global steel markets influence finished steel product prices. Nevertheless, many of our products are SBQ products for which competition is limited, and, therefore, these products tend to generate somewhat higher margins compared with our more commercial steel products. We attempt to adjust the mix of our product output toward higher margin products to the extent that we are able to do so, and we also adjust our overall product levels based on the product demand.

We focus on controlling our cost of sales as well as our selling, general and administrative expenses. Our cost of sales largely consist of the costs of acquiring the raw materials necessary to manufacture steel, primarily scrap metal and ferroalloys. Market supply and demand generally determine scrap prices, and, as a result, we have limited ability to influence their cost or the costs of other raw materials, including energy costs; however, in 2014, 2015, 2016, 2017 and 2018 we did not purchase iron ore pellets or coaking coal since our Lorain, Ohio blast furnace facility, which is our only facility that utilizes these materials, was idled during these periods. There is a correlation between the prices of scrap and iron ore and finished product prices, although the degree and timing of this correlation varies from time to time, so we may not always be able to fully pass along scrap and other raw material price increases to our customers. Therefore, our ability to decrease our cost of sales as a percentage of net sales is largely dependent on increasing our productivity. Our ability to control selling, general and administrative expenses, which do not correlate to net sales as closely as cost of sales do, is a key element of our profitability. Although our revenues and costs fluctuate from quarter to quarter, we do not experience large fluctuations due to seasonality.

Production costs at our U.S. facilities are higher by approximately 69% than those in our facilities in Mexico principally due to the higher cost of labor and the higher cost of ferroalloys used to manufacture SBQ steel, which is the only steel product that we produce in the United States.

The negative operating trends in our USA segment are primarily driven by under-utilized production capacity that severely impacts cost. The automotive sector is stable and continues to provide good demand for our products.

Our U.S. subsidiaries have entered into sale agreements with customers and, in order to comply with the terms thereof, any existing orders pursuant to those agreements need to be fulfilled even if the price of raw material increases with time. As the existing sale agreements expire, we will evaluate new agreements which would result in a production of profitable products.

Typically, about 75% of our business uses a fixed base price that is negotiated annually, plus monthly scrap and alloy surcharges. The remaining 25% is transaction business, where we can adjust the base pricing as required. Scrap metal and commodity prices stabilized somewhat midway through 2016, and in 2017 and 2018 the prices of scrap and other inputs increased significantly. Financial resources will continue to be made available as our U.S. segment tackles the cost curve and restores the business to profitability.

Our results are affected by general global trends in the steel industry and by the economic conditions in the countries in which we operate and in other steel producing countries. Our results are also affected by the specific performance of the automotive, non-residential construction, industrial equipment, tooling equipment and other related industries. Our profitability is also impacted by events that affect the price and availability of raw materials and energy inputs needed for our operations. The factors and trends discussed below also affect our results and profitability.

Our primary source of revenue is the sale of SBQ steel and structural steel products.

In August 2004, we completed the Atlax Acquisition (Tlaxcala and Cholula facilities). In July 2005, we and our controlling shareholder, Industrias CH, completed the acquisition of Republic. We believe that these acquisitions allowed us to become the leading producer of SBQ steel in North America and the leading producer of structural and light structural steel in Mexico, in each case in terms of sales volume. We expect the sale of SBQ steel, structural steel and other steel products to continue to be our primary source of revenue. The markets for our products are highly competitive and highly dependent on developments in global markets for those products. The main competitive factors are price, product quality and customer relationships and service.

Our results are affected by economic activity, steel consumption and end-market demand for steel products.

Our results of operations depend largely on macroeconomic conditions in North America. Historically, there has been a strong correlation between the annual rate of steel consumption and the annual change in gross domestic products (“GDP”) in the Mexican and U.S. markets.

We sell our steel products to the automotive, construction, manufacturing and other related industries. These industries are generally cyclical, and their demand for steel is impacted by the stage of their industry market cycles and the country’s economic performance. Mexico’s GDP increased 2.1% in 2018 (according to preliminary figures of the INEGI) and increased 2% in 2017. The U.S. GDP increased 2.9% in 2018 (according to preliminary figures of the U.S. Department of Commerce) and 2.2% in 2017. Deterioration in economic conditions in the countries in which we operate is likely to adversely affect our results of operation.

Our results are affected by international steel prices and trends in the global steel industry.

Steel prices are generally set by reference to world steel prices, which are determined by global supply and demand trends. As a result of general excess capacity in the industry, the world steel industry was previously subject to substantial downward pricing pressure, which negatively impacted the results of steel companies in the second half of 2000 and all of 2001. International steel prices generally improved beginning in 2003, driven by a strong increase in global demand fostered by economic growth in Asia and an economic recovery in the United States, combined with increased rationalization of production capacity in the United States and elsewhere. Average steel prices continued to improve from 2003 to 2008 due to strong end-market demand fundamentals for a number of key steel-consuming industries, continued strong steel demand in China, India and other developing economies, relatively high raw material and energy costs and reductions in U.S. production from some of the industry’s largest producers.

This period of high prices for steel encouraged reactivation of investment in production capacity, and consequently an increase in the supply of steel products that contributed to a decline in steel prices. As the 2008 financial crisis worsened in late 2008 and early 2009, global demand for steel fell while new steel production capacity was coming into the market, and as a result steel prices fell worldwide. In 2009 the average steel price decreased approximately 22% compared to 2008. Our average steel price increased approximately 4% in 2017 compared to 2016. Our average steel price increased approximately 18.6% in 2018 compared to 2017.

In recent years, there has been a trend toward consolidation of the steel industry. For example, Aceralia, Arbed and Usinor merged in February 2002 to create Arcelor, and LNM Holdings and Ispat International merged in October 2004 to create Mittal Steel, which subsequently acquired International Steel Group. In 2006, Arcelor completed the acquisition of Dofasco in Canada, and Mittal Steel announced the acquisition of Arcelor, forming the largest steel company in the world. In addition, a number of other steel acquisition transactions have been announced, including the acquisition of Oregon Steel by Evraz and the acquisition of Corus by Tata Steel. Consolidation has enabled steel companies to lower their production costs and allowed for more stringent supply-side discipline, including through selective capacity closures or idling, as the ones observed recently in the United States by Mittal Steel, U.S. Steel and others. Consolidation may result in increased competition and could adversely affect our results.

Our results are affected by competition from imports.

Our ability to sell our products is influenced, to a certain degree, by global trade for steel products, particularly trends in imports of steel products into the Mexican and U.S. markets. During 2005, the Mexican government, at the request of CANACERO, implemented several measures to prevent unfair trade practices such as dumping in the steel import market. These measures include initiating anti-dumping and countervailing duty proceedings, temporarily increasing import tariffs for countries with which Mexico does not have free trade agreements. As a result, the competitive price pressure from dumping declined, contributing to a general upward trend in domestic Mexican steel prices. In 2006 and 2007, imports to Mexico increased as market conditions improved, and in 2008, imports to Mexico continued to increase, notwithstanding the worsening of international market conditions. In 2009, however, imports to Mexico decreased as domestic and global market conditions worsened. In 2010, 2011 and 2012, imports to Mexico increased as market conditions improved. In 2013, imports to Mexico decreased as domestic and global market conditions worsened. In 2014, imports to Mexico increased slightly. In 2015, imports to Mexico increased 10% compared to 2014 according to information of CANACERO. In 2016, imports to Mexico increased 1.6% compared to 2015 according to information of CANACERO. In 2017, imports to Mexico in tons increased 6.8% compared to 2016 according to information of CANACERO. In 2018, imports to Mexico in tons increased 4.5% compared to 2017 according to information of CANACERO.

Steel imports to the United States accounted for an estimated 23% of the domestic U.S. steel market in 2018 and an estimated 27% in 2017. Foreign producers typically have lower labor costs, and in some cases are owned, controlled or subsidized by their governments, allowing production and pricing decisions to be influenced by political and economic policy considerations as well as prevailing market conditions. Increases in future levels of imported steel in the United States could reduce future market prices and demand levels for steel in the United States. To this extent, the U.S. Department of Commerce and the U.S. International Trade Commission are currently conducting five year “sunset” reviews of existing trade relief in several different steel products. Imports represent less of a threat to SBQ producers like us in the United States than to commodity steel producers because of the high quality requirements and standard required by buyers of SBQ steel products.

Our results are affected by the cost of raw materials and energy.

We purchase substantial quantities of raw materials, including scrap metal, and ferroalloys for use in the production of our steel products. The availability and price of these inputs vary according to general market and economic conditions and thus are influenced by industry cycles. As a result of the 2008 financial crisis that continues to affect the international markets, the prices of these inputs have remained highly volatile. For example, prices of scrap metal increased approximately 7% in 2014, decreased approximately 16% in 2015, increased approximately 2% in 2016, increased approximately 31% in 2017 and increased

55 

19.4% in 2018; and prices of ferroalloys increased approximately 16% in 2014 and decreased approximately 9% and 13% in 2015 and 2016, respectively, in 2017 increased approximately 22% and increased approximately 9.6% in 2018. As with other raw materials, iron ore and coaking coal prices fluctuate significantly. However, in 2014, 2015, 2016, 2017 and 2018 we did not purchase coaking coal or pellets since our Lorain, Ohio blast furnace facility was idle during this period.

In addition to raw materials, electricity and natural gas are both relevant components of our cost structure. We purchase electricity and natural gas at prevailing market prices in Mexico and the United States. These prices are impacted by general demand and supply for energy in the United States and Mexico as economic activity fueled energy demand and the supply and price of oil was impacted by geopolitical events. While natural gas and electricity prices in the United States and Mexico decreased in response to the financial crisis, they have remained highly volatile. Prices for electricity increased approximately 7% in 2014, decreased approximately 12% in 2015, increased approximately 1.5% in 2016, increased approximately 22% in 2017 and increased approximately 14% in 2018; and prices for natural gas increased approximately 25% in 2014, decreased approximately 23% in 2015, increased approximately 8% in 2016, increased approximately 22% in 2017 and increased approximately 28% in 2018.

If inflation rates in Mexico rise significantly, our costs may increase and the demand for our services may decrease.

Mexico has historically experienced high annual rates of inflation. The annual rate of inflation, as measured by changes in the Mexican national consumer price index (Índice Nacional de Precios al Consumidor) published by the INEGI was 4.1% for 2014, 2.1% for 2015, 3.4% for 2016, 6.8% for 2017 and 4.8% for 2018. High inflation rates could adversely affect our business and results

of operations by increasing certain costs, such as the labor costs of our Mexican facilities, beyond levels that we could pass on to our customers and reducing consumer purchasing power, thereby adversely affecting demand for our products.

Depreciation of the Mexican peso relative to the U.S. dollar, as well as the reinstatement of exchange controls and restrictions, could adversely affect our financial performance.

Depreciation of the Mexican peso relative to the U.S. dollar may negatively affect our results of operations. Since the second half of 2008, the value of the Mexican peso relative to the U.S. dollar has fluctuated significantly. According to the Mexican Central Bank (Banco de Mexico), during the period from 2008 to 2019, the exchange rate registered a low of Ps. 9.92 per U.S.$1.00 at August 6, 2008, and a high of Ps. 20.84 per U.S.$1.00 at January 13, 2017. The appreciation of the Mexican peso relative to the U.S. dollar in 2018 was 0.4%. The exchange rate at December 31, 2018 was 19.6566 compared to 19.7354 at December 31, 2017. At July 30, 2019 the exchange rate was Ps. 19.0900 per U.S.$1.00.

A severe depreciation of the Mexican peso may also result in disruption of the international foreign exchange markets and may limit our ability to convert Mexican pesos into U.S. dollars and other currencies. While the Mexican government does not currently restrict, and has not recently restricted the right or ability of Mexican or foreign persons or entities to convert Mexican pesos into U.S. dollars or to transfer other currencies out of Mexico, it has done so in the past and could reinstate exchange controls and restrictions in the future. Currency fluctuations or restrictions on the transfer of foreign currency outside of Mexico may have an adverse effect on our financial performance.

Segment Information

We are required to disclose segment information in accordance with IFRS 8 “Operating Segments”: Information which establishes standards for reporting information about operating segments in annual financial statements and requires reporting of selected information about operating segments in interim financial reports issued to shareholders. Operating segments are components of a company about which separate financial information is available that is regularly evaluated by the chief operating decision maker(s) in deciding how to allocate resources and assess performance. The statement also establishes standards for related disclosures about a company’s products and services, geographical areas and major customers.

We conduct business in three principal business segments which are organized on a geographical basis:

● our Mexican segment represents the results of our operations in Mexico, including our plants in Mexicali, Guadalajara, Tlaxcala and San Luis Potosí;

● our U.S. segment represents the results of our operations of Republic, including its five plants, located in the United States; and

● our Brazil segment represents the results of our operations in three plants located in Brazil, one of which started operations in June 2015 and two of which started to consolidate operations in May 2018 .

The following information shows other results by segment.

Consolidated Statements of Comprehensive Income

Comparison of Years Ended December 31, 2017 and 2018

Net Sales

Net sales increased 24%, to Ps. 35,678 million in 2018 compared to Ps. 28,700 million in 2017. This increase resulted primarily from a 19% increase in the average price per ton of steel products and an increase of 101,000 tons in shipments of finished steel products. Total sales outside of Mexico increased 27%, to Ps. 15,257 million in 2018 compared to Ps. 11,987 million in 2017. Total sales in Mexico increased 22%, from Ps. 16,713 million in 2017 to Ps. 20,421 million in 2018.

Shipments of finished steel products increased 4.8%, to 2.192 million tons in 2018, compared to 2.091 million tons in 2017. Total sales volume outside of Mexico of finished steel products increased 14.8% to 0.853 million tons in 2018, compared to 0.743 million tons in 2017, while total Mexican sales decreased 0.7%, from 1.348 million tons in 2017, compared to 1.339 million tons in 2018. The average price of steel products increased 18.6% in 2018 compared to 2017.

Cost of Sales

Our cost of sales increased 27%, from Ps. 23,994 million in 2017 to Ps. 30,563 million in 2018, which increase is mainly attributable to a 21.5% increase in the average cost per ton of steel products sold. Cost of sales as a percentage of net sales was 86% in 2018 and 84% in 2017. We experienced higher cost of sales at our Republic facilities, mainly as a result of (i) higher labor costs corresponding to our U.S. operations, and (ii) the higher cost of raw materials, which our U.S. operations use in the production of SBQ steel. Hourly wages at our Mexican operations were approximately U.S.$1.9 (Ps. 36) per hour in 2018 and U.S.$ 1.6 (Ps. 31) per hour in 2017, compared to U.S.$55.3 (Ps.1,087) and U.S.$ 56.4 (Ps. 1,113) per hour for 2018 and 2017, respectively, at our U.S. operations. Although raw material costs are similar in the United States and Mexico, our U.S. operations produce higher value-added SBQ steel, which requires more expensive raw materials such as chromium, nickel, molybdenum and other alloys. Our Mexican operations require these alloys to a lesser extent, because they produce commodity steel as well as SBQ steel.

Gross Profit

Our gross profit was Ps. 5,115 million in 2018 compared to a Ps. 4,706 million gross profit in 2017. This increase in gross profit is attributable mainly to an increase of 101,000 tons of finished steel products shipped, a 18.6% increase in the average price of steel products sold, and a 21.5% increase in the average cost per ton of steel products sold. As a percentage of net sales, our gross profit was 14% in 2018 and our gross profit was 16% in 2017.

Administrative Expenses

Our administrative expenses (including depreciation and amortization) decreased 13%, to Ps. 1,080 million in 2018, compared to Ps. 1,239 million in 2017. The variation of Ps. 159 million corresponds to the decrease of Ps. 162 million in the Mexican segment, the increase of Ps. 11 million in the United States segment and a decrease of Ps. 8 million in the Brazil segment. In 2018 and 2017, our general and administrative expenses included Ps. 10 million of amortization of the tangible and intangible assets registered principally in connection with the acquisition of Republic and Ps. 125 million, of amortization of the tangible and intangible assets registered principally in connection with the acquisition of Grupo San, respectively.

Administrative expenses as a percentage of net sales were 3% in 2018 and 4% in 2017. Depreciation and amortization expense were Ps. 157 million in 2018 compared to Ps. 285 million in 2017.

Other (Income) Expense, Net

We recorded other income, net, of Ps. 15 million in 2018, reflecting (i) income of Ps. 10 million related to the sale of scrap, (ii) expense of Ps. 9 million in land remediation at Pacific Steel, (iii) income of Ps. 6 million for recovery of insurance companies and (iv) income related to other financial operations of Ps. 8 million.

We recorded other income, net, of Ps. 7 million in 2017, reflecting (i) income of Ps. 10 million related to the sale of scrap, (ii) expense of Ps. 7 million in land remediation at Pacific Steel and (iii) income related to other financial operations of Ps. 4 million.

59 

Interest Income

We recorded an interest income of Ps. 313 million in 2018 compared to Ps. 252 million in 2017. This increase is attributable mainly to higher interest rates in the U.S. and Mexico.

Interest Expense

We recorded an interest expense of Ps. 17 million in 2018 compared to Ps. 54 million in 2017. This decrease is attributable mainly to the lesser use of financial services.

Foreign Exchange Loss (Gain)

We recorded a foreign exchange loss of Ps. 147 million in 2018 compared to a foreign exchange loss of Ps. 654 million in 2017; this foreign exchange loss reflected the 0.4% appreciation of the peso against the dollar in 2018, compared to the 4.5% appreciation of the peso against the dollar in 2017.

Income Tax

In 2018 we recorded an income tax provision of Ps. 752 million, which included an income tax provision of Ps. 511 million and an income tax provision for deferred income taxes of Ps. 241 million. In 2017 we recorded an income tax provision of Ps. 1,123 million, which included an income tax provision of Ps. 45 million and an income tax provision for deferred income taxes of Ps. 1,078 million.

Our effective income tax rates for 2018 and 2017 were 16.9% and 38.9%, respectively. According to the Income Tax Law in Mexico, the tax rate for the year 2018 and years thereafter is 30%. We have implemented the practice of recognizing the benefit derived from the amortization of tax losses for the period in which such losses are actually amortized. In 2018 and 2017, we amortized tax losses which generated a benefit on income tax of approximately Ps. 1,238 million and Ps. 115 million, respectively. These effects caused our effective tax rates during 2018 to be lower than the statutory tax rate.

Net Income (Loss)

We recorded net income of Ps. 3,447 million in 2018, compared to net income of Ps. 1,895 million in 2017. The increase in net income for the year 2018 compared to 2017 is mainly as a result of (i) an increase of 101,000 tons of finished steel products shipped, a 18.6% increase in the average price of steel products sold, and a 21.5% increase in the average cost per ton of steel products sold, (ii) in the year 2017 we had Ps. 198 million of interest income compared to the year 2018 where we had Ps. 297 million of interest income, net, (iii) the decrease in the foreign exchange loss in 2018 to Ps. 151 million compared to Ps. 654 million in 2018 and (iv) the decrease in the provision of income taxes in 2018 to Ps. 752 million compared to Ps. 1,123 million in 2017.

 Comparison of Years Ended December 31, 2017 and 2018

Net Sales

Net sales increased to Ps. 5,924 million in 2018 compared to Ps. 3,204 million in 2017. This increase resulted principally from an increase of 133,000 tons of shipments of finished steel products and the 28% increase in the average price per ton of steel products.

Shipments of finished steel products increased to 433,000 tons in 2018 (including the shipment of the new plants acquired in 2018, which began to consolidate operations in May 2018: Cariacica with 115,000 tons and Itauna with 41,000 tons) compared to 300,000 tons in 2017.

Cost of Sales

Our cost of sales increased to Ps. 5,553 million in 2018 compared to Ps. 2,840 million in 2017, which increase is mainly attributable to the increase of the shipments of finished steel products of 133,000 tons in 2018 and a 35% increase in the average cost per ton of steel products sold compared to 2017.

Our gross profit was Ps. 371 million in 2018 compared to Ps. 364 million of gross profit in 2017. The gross profit in the year 2018 remains practically the same as in 2017 due to the fact that the increase by 133,000 tons shipped and the increase in prices of 28% in the tons shipped did not offset the increase of 35% in the average cost of steel products sold. As a percentage of net sales, our gross profit was 6% in 2018, compared to 11% of gross profit in 2017.

Consolidated Statements of Comprehensive Income

Comparison of Years Ended December 31, 2016 and 2017

Net Sales

Net sales increased 4%, to Ps. 28,700 million in 2017 compared to Ps. 27,516 million in 2016. This increase resulted primarily from a 4% increase in the average price per ton of steel products and an increase of 6,000 tons in shipments of finished steel products. Total sales outside of Mexico increased 5%, to Ps. 11,987 million in 2017 compared to Ps. 11,438 million in 2016. Total sales in Mexico increased 4%, from Ps. 16,078 million in 2016 to Ps. 16,713 million in 2017.

Shipments of finished steel products increased 0.3%, to 2.091 million tons in 2017, compared to 2.085 million tons in 2016. Total sales volume outside of Mexico of finished steel products increased 17% to 0.743 million tons in 2017, compared to 0.636 million tons in 2016, while total Mexican sales decreased 10%, from 1.495 million tons in 2016, compared to 1.348 million tons in 2017. The average price of steel products increased 4% in 2017 compared to 2016.

Cost of Sales

Our cost of sales increased 5%, from Ps. 22,776 million in 2016 to Ps. 23,994 million in 2017, which increase is mainly attributable to a 5% increase in the average cost per ton of steel products sold. Cost of sales as a percentage of net sales was 84% in 2017 and 83% in 2016. We experienced higher cost of sales at our Republic facilities, mainly as a result of (i) higher labor costs corresponding to our U.S. operations, and (ii) the higher cost of raw materials, which our U.S. operations use in the production of SBQ steel. Hourly wages at our Mexican operations were approximately U.S.$1.6 (Ps. 31) per hour in 2017 and U.S.$1.4 (Ps. 29) per hour in 2016, compared to U.S.$56.4 (Ps. 1,113) and U.S.$61.3 (Ps. 1,267) per hour for 2017 and 2016, respectively, at our U.S. operations. Although raw material costs are similar in the United States and Mexico, our U.S. operations produce higher value-added SBQ steel, which requires more expensive raw materials such as chromium, nickel, molybdenum and other alloys. Our Mexican operations require these alloys to a lesser extent, because they produce commodity steel as well as SBQ steel.

Gross Profit (Loss)

Our gross profit was Ps. 4,706 million in 2017 compared to a Ps. 4,740 million gross profit in 2016. This gross profit is attributable mainly to an increase of 6,000 tons of finished steel products shipped, a 4% increase in the average price of steel products sold, and a 5% increase in the average cost per ton of steel products sold. As a percentage of net sales, our gross profit was 16% in 2017 and our gross profit was 17% in 2016.

Administrative Expenses

Our administrative expenses (including depreciation and amortization) decreased 3%, to Ps. 1,239 million in 2017, compared to Ps. 1,277 million in 2016. The variation of Ps. 38 million corresponds to the decrease of Ps. 148 million in the Mexican segment, the decrease of Ps. 42 million in the United States segment and an increase of Ps. 152 million in the Brazil segment. In 2017 and 2016, our general and administrative expenses included Ps. 125 million and Ps. 258 million, respectively, of amortization of the tangible and intangible assets registered principally in connection with the acquisition of Grupo San.

Interest Expense

We recorded an interest expense of Ps. 54 million in 2017 compared to Ps. 40 million in 2016. This increase is attributable mainly to the interest rates negotiated with our lenders.

Foreign Exchange Loss (Gain)

We recorded a foreign exchange loss of Ps. 654 million in 2017 compared to an exchange gain of Ps. 1,775 million in 2016; this foreign exchange gain reflected the 4.5% appreciation of the peso against the dollar in 2017, compared to the 19.2% depreciation of the peso against the dollar and the 17% appreciation of the Brazilian real against the dollar in 2016.

Income Tax

In 2017 we recorded an income tax provision of Ps. 1,123 million, which included an income tax provision of Ps. 45 million and an income tax provision for deferred income taxes of Ps. 1,078 million. In 2016 we recorded an income tax provision of Ps. 936 million, which included an income tax provision of Ps. 67 million and an income tax provision for deferred income taxes of Ps. 869 million.

Our effective income tax rates for 2017 and 2016 were 38.9% and 17.6%, respectively. According to the Income Tax Law in Mexico, the tax rate for the year 2017 and years thereafter is 30%. We have implemented the practice of recognizing the benefit derived from the amortization of tax losses for the period in which such losses are actually amortized. In 2017 and 2016, we amortized tax losses which generated a benefit on income tax of approximately Ps. 115 million and Ps. 1,166 million, respectively. These effects caused our effective tax rates during 2016 to be lower than the statutory tax rate.

Net Income (Loss)

We recorded net income of Ps. 1,895 million in 2017, compared to net income of Ps. 4,365 million in 2016. The decrease in net income for the year 2017 compared to 2016 is mainly as a result of (i) the exchange loss of 654 million in 2017 compared to a foreign exchange gain of 1,775 million in 2016, (ii) in the year 2017 we had Ps. 198 million of interest income net compared to the year 2016 where we had Ps. 140 million of interest income net and (iii) the increase in the provision of income taxes in 2017 of Ps. 1,123 million compared to Ps. 936 million in 2016.

We recorded a net income of Ps. 59 million in 2017 compared to Ps. 731 million of net income in 2016. The decrease of our net income in 2017 compared to the net income in 2016 is mainly due to the fact that in 2017 the foreign exchange gain was Ps. 2 million and in 2016 the foreign exchange gain was Ps. 766 million.

Consolidated Statements of Comprehensive Income

Comparison of Years Ended December 31, 2015 and 2016

Net Sales

Net sales increased 12%, to Ps. 27,516 million in 2016 compared to Ps. 24,476 million in 2015. This increase resulted primarily from a 9% increase in the average price per ton of steel products and an increase of 59 thousand tons in shipments of

68 

finished steel products. Total sales outside of Mexico increased 15%, to Ps. 11,438 million in 2016 compared to Ps. 9,932 million in 2015. Total sales in Mexico increased 11%, from Ps. 14,543 million in 2015 to Ps. 16,078 million in 2016.

Shipments of finished steel products increased 3%, to 2.085 million tons in 2016, compared to 2.026 million tons in 2015. Total sales volume outside of Mexico of finished steel products increased 0.6% to 0.636 million tons in 2016, compared to 0.632 million tons in 2015, while total Mexican sales volume decreased 0.2%, from 1.452 million tons in 2015, compared to 1.449 million tons in 2016. The average price of steel products increased 9% in 2016 compared to 2015.

Cost of Sales

Our cost of sales decreased 1%, from Ps. 23,097 million in 2015 to Ps. 22,776 million in 2016, which decrease is mainly attributable to a 4% decrease in the average cost per ton of steel products sold and the impairment recorded of the coaking coal inventory. Cost of sales as a percentage of net sales was 83% in 2016 and 94% in 2015. We experienced higher cost of sales at our Republic facilities, mainly a result of (i) higher labor costs corresponding to our U.S. operations, and (ii) the higher cost of raw materials, which our U.S. operations use in the production of SBQ steel. Hourly wages at our Mexican operations were approximately U.S.$1.4 (Ps. 29) per hour in 2016 and U.S.$1.7 (Ps. 35) per hour in 2015, compared to U.S.$61.3 (Ps. 1,267) and U.S.$52.5 (Ps. 1,085) per hour for 2016 and 2015, respectively, at our U.S. operations. Although raw material costs are similar in the United States and Mexico, our U.S. operations produce higher value-added SBQ steel, which requires more expensive raw materials such as chromium, nickel, molybdenum and other alloys. Our Mexican operations require these alloys to a lesser extent, because they produce commodity steel as well as SBQ steel.

Gross Profit (Loss)

Our gross profit was Ps. 4,740 million in 2016 compared to a Ps. 693 million gross loss in 2015. This gross profit is attributable mainly to an increase of 59 thousand tons of finished steel products shipped, a 9% increase in the average price of steel products sold, a 4% decrease in the average cost per ton of steel products sold and in 2015 we registered the impairment of property, plant and equipment of Ps. 2,072 million (U.S. $130.7 million). As a percentage of net sales, our gross profit was 17% in 2016 and our gross loss was 3% in 2015.

Administrative Expenses

Our administrative expenses (including depreciation and amortization) decreased 19%, to Ps. 1,277 million in 2016, compared to Ps. 1,582 million in 2015. The decrease of Ps. 305 million in 2016 compared to 2015 is attributable principally to the fact that in 2015 we made the following payments, which we did not make in 2016: (i) Ps. 178 million in royalties to Industrias CH for use of their brands, (ii) Ps. 78 million related to fees for legal services and (iii) expenses of Ps. 76 million corresponding to severance payments in Republic, which were made in 2015. In 2016 and 2015, our general and administrative expenses included Ps. 258 million and Ps. 256 million, respectively, of amortization of the tangible and intangible assets registered principally in connection with the acquisition of Grupo San.

Operating expenses as a percentage of net sales were 5% in 2016 and 6% in 2015. Depreciation and amortization expense were Ps. 398 million in 2016 compared to Ps. 419 million in 2015.

Other (Expense) Income, Net

We recorded other expense, net, of Ps. 36 million in 2016, reflecting (i) income of Ps. 10 million related to the sale of scrap, (ii) expense of Ps. 35 million in the dismantling of machinery and (iii) an expense related to other financial operations of Ps. 11 million.

We recorded other income, net, of Ps. 173 million in 2015, reflecting (i) income of Ps. 4 million related to the sale of scrap, (ii) income of Ps. 174 million related to proceeds from a settlement with a client and (iii) an expense related to other financial operations of Ps. 5 million.

Interest Income

We recorded an interest income of Ps. 140 million in 2016 compared to Ps. 34 million in 2015. This increase is attributable mainly to better interest rates negotiated with financial services institutions.

Interest Expense

We recorded an interest expense of Ps. 40 million in 2016 compared to Ps. 40 million in 2015.

69 

Foreign Exchange Gain (Loss)

We recorded a foreign exchange gain of Ps. 1,775 million in 2016 compared to an exchange loss of Ps. 382 million in 2015; this foreign exchange gain reflected the 19.2% depreciation of the peso against the dollar and the 17% appreciation of the Brazilian real against the dollar in 2016, compared to the 47% depreciation of the Brazilian real against the dollar and the 17.7% depreciation of the peso against the dollar in 2015.

Income Tax

In 2016 we recorded an income tax provision of Ps. 936 million, which included an income tax provision of Ps. 67 million and an income tax provision for deferred income taxes of Ps. 869 million. In 2015 we recorded an income tax provision of Ps. 771 million, which included an income tax provision of Ps. 1,598 million and an income tax benefit for deferred income taxes of Ps. 827 million. The income tax of 2015 includes Ps. 1,333 million that was paid by Simec International 6 S.A. de C.V. and Simec International 8 S.A. de C.V. arising from a review by the tax authority initiated in July 2015 to the fiscal year ended December 31, 2010, due to a difference of opinion on the deduction of losses on disposal of treasury bonds of the United States.

Our effective income tax rates for 2016 and 2015 were 17.6% and 22.5%, respectively. According to the Income Tax Law in Mexico, the tax rate for the year 2016 and years thereafter is 30%. We have implemented the practice of recognizing the benefit derived from the amortization of tax losses for the period in which such losses are actually amortized. In 2016 and 2015, we amortized tax losses which generated a benefit on income tax of approximately Ps. 1,166 million and Ps. 39 million, respectively. These effects caused our effective tax rates during 2016 and 2015 to be lower than the statutory tax rate.

Net Income (Loss)

We recorded net income of Ps. 4,365 million in 2016, compared to net loss of Ps. 3,261 million in 2015. This income is attributable mainly to (i) an increase of 59,000 tons of shipments of finished steel products, (ii) an increase of 9% in the average price of steel products sold, (iii) the 4% decrease in the average cost per ton of steel products sold and (iv) a foreign exchange gain of Ps. 1,775 million in 2016 compared to Ps. 382 million of foreign exchange loss in 2015.

Gross Profit

Our gross profit decreased 29%, to Ps. 2,637 million in 2016 compared to Ps. 3,731 million in 2015. This decrease is attributable mainly to an increase of 18% in the average cost of steel products sold. As a percentage of net sales, our gross profit was 16% in 2016, compared to 25% in 2015.

Administrative Expenses

Our administrative expenses (including depreciation and amortization) decreased 18%, to Ps. 902 million in 2016, compared to Ps. 1,101 million in 2015. Such decrease is attributable principally to the fact that in 2015 we had an administrative expense of Ps.

70 

178 million in royalties paid to Industrias CH for use of their brands, which we did not have in 2016. In 2016 and 2015, our general and administrative expenses included Ps. 245 million and Ps. 245 million, respectively, of amortization of the tangible and intangible assets registered principally in connection with the acquisition of Grupo San.

Interest Expense

We recorded an interest expense of Ps. 15 million in 2016 compared to Ps. 10 million in 2015. This increase was principally due to commissions payable to our financial services providers.

Foreign Exchange Gain (Loss)

We recorded a foreign exchange gain of Ps. 2,343 million in 2016 compared to an exchange gain of Ps. 840 million in 2015; this foreign exchange reflected the 19.2% depreciation of the peso against the dollar in 2016.

Income Tax

In 2016, we recorded an income tax provision of Ps. 678 million, which included an income tax provision of Ps. 17 million and an income tax provision for deferred income taxes of Ps. 661 million.

Critical Accounting Policies

The discussion in this section is based upon our consolidated financial statements, which have been prepared in accordance with IFRS. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at year-end, and the reported amount of revenues and expenses during the year. Management regularly evaluates these estimates, including those related to the carrying value of property, plant and equipment and other non-current assets, inventories and cost of sales, income taxes, foreign currency transactions and exchange differences, liabilities for deferred income taxes, valuation of financial instruments, obligations relating to employee benefits, potential tax deficiencies, environmental obligations, and potential litigation claims and settlements. Management estimates are based on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent

73 

from other sources. Accordingly, actual results may differ materially from current expectations under different assumptions or conditions.

Management believes that the critical accounting policies which require the most significant judgments and estimates used in the preparation of the financial statements relate to deferred income taxes, the impairment of property, plant and equipment, impairment of intangible assets, valuation allowance on accounts receivable and inventories obsolescence. We evaluate the recoverability of operating tax losses (NOL) carry forwards, and only for those who have probability of being recovered is determined a deferred tax asset. The final realization of deferred tax assets depends on the generation of taxable profits in the periods when the temporary differences are deductible. Upon carrying out this evaluation, we considered the expected reversal of deferred tax liabilities, projected taxable profit and planning strategies. Based on the company’s evaluation, it determined the amount of deferred tax assets that is more likely than not to be realized in the future against those taxable profits.

We evaluate periodically the adjusted values of our property, plant and equipment and intangible assets to determine whether there is an indication of potential impairment. Impairment exists when the carrying amount of an asset exceeds net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value. Assets to be disposed of are reported at the lower of the carrying amount or realizable value. Significant judgment is involved in estimating future revenues and cash flows or realizable value, as applicable, of our property, plant and equipment due to the characteristics of those assets. The class of our assets which most require complex determinations based upon assumptions and estimates relates to indefinite lived intangibles including goodwill, due to the current market environment.

In June of 2015 Republic Steel temporarily idled the newly constructed electric arc furnace at the Lorain, Ohio, facility in response to the severe economic downturn in the energy exploration sector following the sharp drop in the price of oil which has led to significant market declines and demand for product. As a consequence of this event management determined a triggering event took place to where the long-lived assets at the Lorain facility may not be fully recoverable. Management performed an analysis of the fair value of the Lorain facility with the assistance of an independent valuation firm and determined the net book value exceeded the fair value by approximately U.S.$130.7 million (Ps. 2,701 million) and as such recognized an asset impairment of this amount during the year ended December 31, 2015. The fair value determination at the Lorain facility was based on an independent valuation of the Lorain melt shop assets using the comparable match method of the market approach. The income approach was not considered an appropriate fair value measurement due to the absence of reliable forecast data as the facility was idled indefinitely in early 2016.

As of the date of this report, management has no near-term plans to restart the facility. The expectation is that it will be restarted when market conditions improve substantially, particularly in the oil and gas industry. We have property, plant and equipment with a net book value of approximately U.S.$32.7 million (Ps. 643 million) as of December 31, 2018, pertaining to the Lorain, Ohio, facility after recording the impairment charge of U.S.$130.7 million (Ps. 2,701 million) in 2015 (the impairment charge did not impact the cash flows, as it was not a cash expenditure). Management further assessed if there were any impairments at the Company’s other asset groups in accordance with IFRS and determined that as of December 31, 2018, no other asset groups were impaired based on current projections. No further impairment was considered necessary or appropriate.

In assessing the recoverability of the goodwill and other intangibles, we must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the respective assets. We perform an annual review in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if the carrying value of recorded goodwill is impaired. The impairment review process compares the fair value of the reporting unit in which goodwill resides to its carrying value. We estimate the reporting unit’s fair value based on a discounted future cash flow approach that requires estimating income from operations. In order to estimate our cash flows used in impairment computations, we considered the following:

● our history of earnings;

● our history of capital expenditures;

● the remaining useful lives of our primary assets;

● current and expected market and operating conditions; and

● our weighted average cost of capital.

Other intangible assets are mainly comprised of trademarks, customer list and non-competition agreements. When impairment indicators exist, or at least annually for indefinite live intangibles, we determine our projected revenue streams over the estimated useful life of the asset. In order to obtain undiscounted and discounted cash flows attributable to each intangible asset, such revenues are adjusted for operating expenses, changes in working capital and other expenditures as applicable, and discounted to net

74 

present value using the risk adjusted discount rates of return. As of December 31, 2017 and 2018 there was no impairment charge to other intangible assets.

As a result of the downturn in the construction industry in Mexico during 2009 and the negative impact the downturn had on our operations mainly at the San Luis facilities, in which goodwill resides we adjusted the key assumptions used in the valuation model. As of December 31, 2017 and 2018, there was no impairment charge related to the San Luis facilities.

As of December 31, 2018, the main key assumptions used in the valuation models of the San Luis reporting unit are as follows:

● discount rate: 14.5%; and

● sales: we estimate an increase in sales volume of approximately 13% in 2019, mainly attributable to the increase in volume due to the start of production of the new industrial wire product line. After 2020, no sales increases in volume terms are considered in the valuation model. For the year 2019 we estimate a decrease in sales prices of 9.6% and for the years after 2020, only an increase in sales prices in line with estimated inflation.

If these estimates or their related assumptions for prices and demand change in the future, we may be required to record additional impairment charges for these assets.

With respect to valuation allowance on accounts receivable, on a periodic basis management analyzes the recoverability of accounts receivable in order to determine if, due to credit risk or other factors, some receivables may not be collected. If management determines that such a situation exists, the book value of the non-recoverable assets is adjusted and charged to the income statement through an increase in the doubtful accounts allowance. This determination requires substantial judgment by management. As a result, final losses from doubtful accounts could differ significantly from estimated allowances.

We apply judgment at each balance sheet date to determine whether the slow moving inventory is impaired. Inventory is impaired when the carrying value is greater than the net realizable value.

The reserve for environmental liabilities represent the estimated environmental remediation costs that we believe are going to incur. These estimates are based on currently available data, existing technology, the current laws and regulations and take into account the likely effects of inflation and other economic and social factors. The time in which we could incur these costs cannot be determined reliably at this time due to the absence of deadlines for remediation under the laws and regulations which apply to remediation costs will be made.

B. Liquidity and Capital Resources

On December 31, 2018, our total consolidated debt was Ps. 5.936 million (U.S.$302,000) of 8 7/8% medium-term notes (“MTNs”) due 1998 which remained outstanding after we conducted exchange offers for the MTNs in October 1997 and August of 1998. We could not identify the holders of such MTNs at the time of the exchange offers and as a result such MTNs, which matured in 1998, have not been paid and remain outstanding.

On September 6, 2006, Industrias CH and its subsidiaries and affiliates made available a line of credit in favor of Republic. Effective January 1, 2009, Industrias CH reduced the interest rate from 5.23% to 0.25% per annum. As of December 31, 2018, the credits to Industrias CH and its subsidiaries and affiliates were liquidated and as of December 31, 2017, Republic had Ps. 985 million (comprised of U.S.$38 million and Ps. 227 million, including interest), respectively, outstanding under this line of credit. See Note 18 to our consolidated financial statements included elsewhere herein.

We depend heavily on cash generated from operations as our principal source of liquidity. Other sources of liquidity have included financing made available to us by our parent Industrias CH (primarily in the form of equity or debt, substantially all of which was subsequently converted to equity), primarily for the purpose of repaying third party indebtedness, as well as limited amounts of vendor financing. On February 8, 2007, we completed a public offering of ADSs and series B shares and raised cash proceeds of approximately Ps. 2,421 million (U.S.$214 million). As of December 31, 2013 we had cash and cash equivalents of Ps. 6,985 million, as of December 31, 2014 we had cash and cash equivalents of Ps. 7,003 million, as of December 31, 2015 we had cash and cash equivalents of Ps. 6,224 million, as of December 31, 2016 we had cash and cash equivalents of Ps. 7,536 million, as of December 31, 2017 we had cash and cash equivalents of Ps. 7,204 million and as of December 31, 2018 we had cash and cash equivalents of Ps. 6,987 million. We believe that this amount of cash generated from operations will be sufficient to satisfy our currently anticipated cash requirements, including our currently anticipated capital expenditures.

Our principal use of cash has generally been to fund our operating activities, to acquire businesses and to fund our capital expenditure programs. The following is a summary of cash flows for the three years ended December 31, 2016, 2017 and 2018:

Principal Cash Flows

Our net funds used by financing activities in 2018 were Ps. 2,641 million, compared to Ps. 374 million used by financing activities in 2017.

Item 6. Directors, Senior Management and Employees

A. Directors and Senior Management

Our Board of Directors

Our board of directors is responsible for managing our business. Pursuant to our by-laws, the board of directors shall consist of a maximum of 21 but not less than five members elected at an ordinary general meeting of shareholders. Our board of directors currently consists of five directors, each of whom is elected at the annual shareholders’ meeting for a term of one year with an additional period of thirty days, if a successor has not been appointed. The board of directors may appoint provisional directors until the shareholders’ meeting appoints the new directors. Under the Mexican Securities Market Law and our bylaws, at least 25% of our directors must be independent. Under the law, the determination as to the independence of our directors made by our shareholders’ meeting may be contested by the CNBV. In compliance with our bylaws and applicable Mexican law, our board of directors meets on a quarterly basis and resolutions adopted by a majority of directors at the meeting are valid resolutions.

Election of the Board of Directors

At each shareholders’ meeting for the election of directors, the holders of shares are entitled pursuant to our by-laws to elect the directors. Each person (or group of persons acting together) holding 10% of our capital stock is entitled to designate one director.

The current members of our board of directors were nominated and elected to such position at the 2019 general meeting of shareholders as proposed by Industrias CH. We expect that Industrias CH will be in a position to continue to elect the majority of our directors and to exercise substantial influence and control over our business and policies and to influence us to enter into transactions with Industrias CH and affiliated companies. However, our by-laws provide that at least 25% of our directors must be independent from us and our affiliates, and our board of directors has passed a resolution requiring the approval of at least two independent directors for certain transactions between us and our affiliates which are not our subsidiaries.

Under Mexican law, a majority shareholder has no fiduciary duty to minority shareholders but may not act contrary to the interests of the corporation for the majority shareholder’s benefit. Such a majority shareholder is required to abstain from voting on any matter in which it directly or indirectly has a conflict of interest and can be liable for actual and consequential damages if such matter passes as a result of its vote in favor thereof. In addition, the directors of a Mexican corporation owe a duty to act in a manner which, in their independent judgment, is in the best interests of the corporation and all its shareholders.

Our board of directors adopted a code of ethics in December 2002.

78 

Authority of the Board of Directors

The board of directors is our legal representative. The board of directors must approve, among other matters, the following:

● our general strategy;

● annual approval of the business plan and the investment budget;

● capital investments not considered in the approved annual budget for each fiscal year;

● proposals to increase our capital or that of our subsidiaries;

● with input from the Audit Committee, on an individual basis: (i) any transactions with related parties, subject to certain limited exceptions, (ii) our management structure and any amendments thereto, and (iii) the election of our chief executive officer, his compensation and removal for justified causes; (iv) our financial statements and those of our subsidiaries, (v) unusual or non- recurrent transactions and any transactions or series of related transactions during any calendar year that involve (a) the acquisition or sale of assets with a value equal to or exceeding 5% of our consolidated assets or (b) the giving of collateral or guarantees or the assumption of liabilities, equal to or exceeding 5% of our consolidated assets, and (vi) contracts with external auditors and the chief executive officer annual report to the shareholders’ meeting;

● calling shareholders’ meetings and acting on their resolutions;

● any transfer by us of shares in our subsidiaries;

● creation of special committees and granting them the power and authority, provided that the committees will not have the authority which by law or under our by-laws is expressly reserved for the board of directors or the shareholders;

● determining how to vote the shares that we hold in our subsidiaries; and

● the exercise of our general powers in order to comply with our corporate purpose.

Meetings of the board of directors will be validly convened and held if a majority of our members are present. Resolutions at the meetings will be valid if approved by a majority of the members of the board of directors, unless our by-laws require a higher number. The chairman has a tie-breaking vote. Notwithstanding the board’s authority, our shareholders pursuant to decisions validly taken at a shareholders’ meeting at all times may override the board.

Duty of Care and Duty of Loyalty

The Mexican Securities Market Law imposes a duty of care and a duty of loyalty on directors. The duty of care requires our directors to act in good faith and in the best interests of the company. In carrying out this duty, our directors are required to obtain the necessary information from the executive officers, the external auditors or any other person to act in the best interests of the company. Our directors are liable for damages and losses caused to us and our subsidiaries as a result of violating their duty of care.

The duty of loyalty requires our directors to preserve the confidentiality of information received in connection with the performance of their duties and to abstain from discussing or voting on matters in which they have a conflict of interest. In addition, the duty of loyalty is violated if a shareholder or group of shareholders is knowingly favored or if, without the express approval of the board of directors, a director takes advantage of a corporate opportunity. The duty of loyalty is also violated, among other things, by (i) failing to disclose to the audit and corporate practices committee or the external auditors any irregularities that the director encounters in the performance of his or her duties or (ii) disclosing information that is false or misleading or omitting to record any transaction in our records that could affect our financial statements. Directors are liable for damages and losses caused to us and our subsidiaries for violations of this duty of loyalty. This liability also extends to damages and losses caused as a result of benefits obtained by the director or directors or third parties, as a result of actions of such directors.

Our directors may be subject to criminal penalties of up to 12 years’ imprisonment for certain illegal acts involving willful misconduct that result in losses to us. Such acts include the alteration of financial statements and records.

Liability actions for damages and losses resulting from the violation of the duty of care or the duty of loyalty may be exercised solely for our benefit and may be brought by us, or by shareholders representing 5% or more of our capital stock, and criminal actions only may be brought by the Mexican Ministry of Finance, after consulting with the CNBV. As a safe harbor for

79 

directors, the liabilities specified above (including criminal liability) will not be applicable if the director acting in good faith (i) complied with applicable law, (ii) made the decision based upon information provided by our executive officers or third-party experts, the capacity and credibility of which could not be subject to reasonable doubt, (iii) selected the most adequate alternative in good faith or if the negative effects of such decision could not have been foreseeable, and (iv) complied with shareholders’ resolutions provided the resolutions do not violate applicable law.

The members of the board are liable to our shareholders only for the loss of net worth suffered as a consequence of disloyal acts carried out in excess of their authority or in violation of our by-laws.

In accordance with the Mexican Securities Market Law, supervision of our management is entrusted to our board of directors, which shall act through an audit and corporate practices committee for such purposes, and to our external auditor. The audit and corporate practices committee (together with the board of directors) replaces the statutory auditor (comisario) that previously had been required by the Mexican Corporations Law. See Item 6.C. “— Committees” below.

The following table sets forth the names of the members of our board of directors and the year of their initial appointment:

For the Brazil operations, approximately 92% of the employees are under collective bargaining agreements, with Sindicato dos Metalúrgicos de Pindamonhangaba, Moreira César e Roseira afiliado a CUT, which expires on August 31, 2019 (plant in Pindamonhangaba) and Sindicato dos Trabalhadores nas Industrias Metalúrgicas, Mecânicas, de Material Elétrico e Eletrônico do Estado do Espirito Santo (plant in Cariacica), which expires on September 30, 2019.

Defined Contribution Plans

Steelworkers Pension Trust

Republic participates in the Steelworkers Pension Trust (SPT), a defined benefit multi-employer pension plan. While this plan provides defined benefits as a result of lack of information, the company accounts for the plan as a defined contribution plan. Specifically, the plan does not maintain accounting records for purposes of IFRS presentation and does not provide enough information to allocate amounts between participating employers’.

The company obligations to the plan are based upon fixed contribution requirements. The company contributes a fixed dollar amount of U.S.$1.68 (Ps. 33) per hour for each covered employee’s contributory hours, as defined under the plan.

Participation in a multi-employer pension plan agreed to under the terms of a collective bargaining agreement differs from a traditional qualified single employer defined benefit pension plan. The SPT shares risks associated with the plan in the following respects:

- Contributions to the SPT by the Company may be used to provide benefits to employees of other participating employers;

- If a participating employer stops contributing to the SPT, the unfunded obligations of the plan may be borne by the remaining participating employers; and

- If Republic chooses to stop participating in the SPT, the Company may be required to pay an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

On March 21, 2011, the Board of Trustees of the SPT elected funding relief which has the effect of decreasing the amount of required minimum contributions in near-term years, but will increase the minimum funding requirements during later plan years. As a result of the election of funding relief, the SPT’s zone funding under the Pension Protection Act may be impacted.

In addition to the funding relief election, the Board of Trustees also elected a special amortization rule, which allows the SPT to separately amortize investment losses incurred during the SPT’s December 31, 2008 plan year-end over a 29 year period, whereas they were previously required to be amortized over a 15 year period.

Republic’s participation in the SPT for the annual periods ended December 31, 2018 and 2017, is outlined in the table below.

		Pension Protection Act Zone Status(a)					Republic Steel Contributions  (U.S.$ in thousands)				Surcharge Imposed(c)
Pension Fund	EIN/ Pension Plan Number	2018		2017		FIP/RP Status Pending/ Implemented(b)	2018		2017		2018		2017		Expiration of Collective Bargaining Agreement
Steelworkers Pension Trust	23-6648508/499		Green		Green	No	$	2,366	$	2,467		No		No	August 15, 2019

83 

(a) The zone status is based on information that Republic received from the plan and is certified by the plan’s actuary. Among other factors: plans in the green zone are at least 80% funded, plans in the yellow zone are less than 80% funded, and plans in the red zone are less than 65% funded.

(b) Indicates if a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented.

(c) Indicates whether there were charges to Republic from the plan.

Republic has not been listed in the plans’ Forms 5500 as providing more than five percent of the total contributions for any plan years.

There have been no significant changes that affect the comparability of 2018 and 2017 contributions.

VEBA Benefit Trust

Republic is required to make quarterly contributions to the VEBA Benefit Trust as determined by the terms of the USW collective bargaining agreement. The VEBA Benefit Trust is a health and welfare plan for USW retiree healthcare benefits, and is not a “qualified” plan under the regulations of the Employee Retirement Income Security Act of 1974 (ERISA). Under the terms of the extended collective bargaining agreement referred to above, the Benefit Trust contributions have been reduced from U.S.$2.6 million (Ps. 54 million) to U.S.$0.25 million (Ps. 5 million) million per quarter, effective August 16, 2016. For the years ended December 31, 2018 and 2017, the company recorded expenses of Ps. 19.2 million (U.S.$1 million) and Ps. 19 million (U.S.$1 million), respectively, related to the Benefit Trust.

Republic recorded combined expenses of Ps. 69.2 million (U.S.$3.6 million) and Ps. 66 million (U.S.$3.5 million) for the years ended December 31, 2018 and 2017, respectively, related to the funding obligations of the Benefit Trust and SPT.

401(k) Plans

Republic has a defined contribution 401(k) retirement plan that covers substantially all salaried and nonunion hourly employees. This plan is designed to provide retirement benefits through company contributions and voluntary deferrals of employees’ compensation. The company funds contributions to this plan each pay period based upon the participant’s age and service as of January first of each year. The amount of the company’s contribution is equal to the monthly base salary multiplied by the appropriate percentage based on age and years of service. The contribution becomes 100% vested upon completion of three years of vesting service. In addition, employees are permitted to make contributions into a 401(k) retirement plan through payroll deferrals. The company provides a 25.0% matching contribution for the first 5.0% of payroll that an employee elects to contribute. Employees are 100% vested in both their and the Company’s matching 401(k) contributions. For the years ended December 31, 2018 and 2017, the company recorded expense of Ps. 19.2 million (U.S.$1 million) and Ps. 15.1 million (U.S.$0.8 million), respectively, related to this defined contribution retirement plan.

Employees who are covered by the USW labor agreement are eligible to participate in the defined contribution 401(k) retirement plan through voluntary deferrals of employees’ compensation. There are no company contributions or employer matching contributions relating to these employees.

Profit Sharing Plans and Incentive Compensation Plans

The labor agreement includes a profit sharing plan to which Republic is required to contribute 2.5% of its quarterly pre-tax income, as defined in the labor agreement. At the end of each year, the contribution is based upon annual pre-tax income up to U.S.$50.0 million (Ps. 1,033 million) multiplied by 2.5%, U.S.$50.0 million (Ps. 1,033 million) to U,S.$100.0 million (Ps. 2,066 million) multiplied by 3.0%, and above U.S.$100.0 million (Ps. 2,066 million) multiplied by 3.5%, less the previous payouts during the year. An expense of Ps. 1.9 million (U.S. $0.1 million) was recorded during 2018 and no expense was recorded during 2017.

Republic has a profit sharing plan for all salaried and nonunion hourly employees. During 2012, the profit sharing plan was based upon achieving target Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA) amounts, as these are defined within the plan. During 2018 and 2017, the profit sharing plan was based upon achieving certain inventory and shipment targets. During the years ended December 31, 2018 and 2017, Republic paid Ps. 15.4 million (U.S.$0.8 million) and Ps.17 million (U.S.$0.9 million), respectively, to employees covered by the profit sharing plans.

Sigosa Loan

In 2016, we entered into a loan arrangement with Sigosa, a subsidiary of Industrias CH. The purpose of the loan was to provide funding in connection with a strategic joint venture in the seam-welded tube business line between Tuberias Procarsa, S.A. de C.V. (“Procarsa”), a subsidiary of Industrias CH, and Quality Tube, S.A. de C.V. The funding was provided to Procarsa through a series of intercompany loans amongst subsidiaries of Industrias CH. The loan to Sigosa was memorialized under a current account agreement, dated as of November 30, 2016. The current account agreement provided that the term of the loan was indefinite, but could be terminated by either party upon 30 day’s written notice. In addition, the current account agreement provided that amounts advanced under the agreement would bear interest at the Interbank Interest Rate of Equilibrium (TIIE) (Tasa de Interés Interbancaria de Equilibrio) plus 1%, and that interest will accrue and be payable upon the final repayment and termination of the loan.

As of December 31, 2016, the total amount advanced under the Sigosa current account agreement was U.S. $32.9 million. In January 2017, the debt was converted into Mexican pesos at the exchange rate of Ps. 21.9076 for $1.00 USD, resulting in an outstanding balance of Ps. 721.4 million. As of December 31, 2017, the outstanding balance was Ps. 806.4 million, consisting of outstanding principal of Ps. 721.4, and accrued interest of Ps. 85.0 million (consisting of accrued interest of Ps. 24.6 million in 2016 and Ps. 60.4 million in 2017). As of December 31, 2018, the outstanding balance of the loan was Ps. 579.0 million, resulting from payments in the amount of Ps. 297.0 million during 2018, plus an adjustment of Ps. 4.0 million related to the conversion from U.S. dollars to pesos, plus accrued interest in 2018 of Ps. 65.6 million. In the event that Sigosa fails to repay the outstanding balance, it will be paid by Industrias CH.

Ninzi Loan

In August 2016, we entered into a loan arrangement with Proyectos Comerciales el Ninzi, S.A. de C.V., a subsidiary of Controladora VG, S.A. de C.V. (“CVG”) and an affiliate of the Company. CVG is a holding company that is 100% owned by the members of the Vigil family, and is controlled by Mr. Rufino Vigil, chairman of our board of directors. In 2016, we advanced net proceeds of Ps. 1,549.4 million to Ninzi to facilitate the acquisition of companies engaged in the seam-welded tube business line. As of December 31, 2016, the outstanding balance of the loan was Ps. 1,571.0 million, which included Ps. 18.9 million of accrued interest and Ps. 2.8 million of value added tax. As of December 31, 2017, the outstanding balance of the loan was Ps. 1,695.9 million, which included Ps. 124.9 million of accrued interest. As of December 31, 2018, the balance of the outstanding loan was Ps. 376.8 million, as a result of Ps. 1,455.1 million in loan payments made by Ninzi to the Company, offset by accrued interest of Ps. 136.0 million. Interest on this loan is charged at the Interbank Interest Rate of Equilibrium (TIIE) (Tasa de Interés Interbancaria de Equilibrio) plus 1%, and will accrue and become payable upon the final repayment and termination of the loan. While certain negotiations and due diligence of acquisitions were ongoing, Ninzi used the loan proceeds to purchase an aggregate amount of 29,007,216 shares of series B common stock in the Mexican open market. See “Item 16 E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers” herein for further discussion. The value of the shares purchased by Ninzi increased, resulting in an unrealized gain of Ps. 125.3 million. After adding interest and taxes payable, Ninzi paid the Company Ps. 165.1 million in 2018 to provide us with the benefit of the unrealized gain. As of December 31, 2018, Ninzi did not own any series B common shares of the Company. In the event that Ninzi fails to repay the outstanding balance, it will be paid by either CVG or Mr. Rufino Vigil.

Other Loans to Related Parties

In 2017, we made two loans to Industrias CH. The first loan was for U.S. $21.4 million, and accrues interest at a rate of LIBOR plus 1%. The second loan was for Ps. 89.4 million, and accrues interest at a rate of TIIE plus 1%. Interest will accrue and be paid upon the final repayment and termination of the loans. In 2018, we made two additional loans to Industrias CH. The first loan was for U.S. $25.4 million, and accrues interest at a rate of LIBOR plus 1%. The second loan was for Ps. 186.7 million, and accrues interest at a rate of TIIE plus 1%. Interest will accrue and be paid upon the final repayment and termination of the loans.

Legal Proceedings

Mexico

On January 19, 2017, we received a letter issued by the General Director of Crimes and Sanctions of the Comisión Nacional Bancaria y de Valores (National Banking and Securities Commission) (the “CNBV”), notifying us that certain actions in connection with the repurchase of our own shares could be contrary to the provisions of the Ley del Mercado de Valores (Securities Market Law) (the “LMV”). In December 2017, the General Direction of Crimes and Sanctions of the CNBV fined the Company with the amount of Ps. 545,000. Grupo Simec appealed for reconsideration before the CNBV itself, which was favorable to Grupo Simec in 2018, and the fine was left without effect.

During 2018, the Company and certain of its subsidiaries were subject to audits by the Mexican tax authorities for the years 2013 to 2017, resulting in a demand by such tax authorities of a further payment of approximately Ps. 5,900 million. We are contesting such additional amounts in the Mexican courts, and to the date of this report the payment of these additional amounts has not been enforced.

The tax authorities in Mexico have the right to review the previous five years and could determine differences in taxes payable, plus corresponding adjustments, interest and fines.

United States and Canada

On February 13, 2017, the Securities and Exchange Commission (the “SEC”) notified us that the SEC was conducting an informal, and non-public, inquiry into the Company in connection with our internal controls. After cooperating with the SEC, we settled certain internal controls charges with the SEC on January 29, 2019. We agreed to retain an independent consultant to remediate our material weaknesses and to pay a civil monetary penalty in the amount of US$200,000.

88 

In connection with a sales and use tax audit by the Ohio Department of Taxation covering the period from January 1, 2009 through December 31, 2012, an assessment of U.S.$2.4 million (Ps. 47.4 million) (including interest of $0.4 million, Ps. 7.9 million) was issued against Republic on December 9, 2016. The Company disagrees with the assessment in its entirety and has filed a Petition for Reassessment on January 30, 2017, appealing the assessment with the Ohio Board of Tax Appeals. The Company's position is that the assessment that certain services were taxable is substantively incorrect, and based upon a misinterpretation of the relevant regulations and a misunderstanding of the facts that led the Company to determine that the services qualified for Ohio’s sales and use tax exemption for manufacturers. Due to the nature of this matter and its early stages, the Company is unable to determine the amount of loss, if any, it may sustain.  Accordingly, the Company has not recorded an expense in fiscal 2018 or 2017 recognizing the assessment or any estimated settlement amount.

The tax authorities in the United States have the right to review the previous three years and could determine differences in taxes payable, plus corresponding adjustments, surcharges and fines.

The tax authorities in Canada have the right to review the previous four years and could determine differences in taxes payable, plus corresponding adjustments, surcharges and fines.

Our operations in the United States and Canada have been the subject of various environmental claims, including those described below. The resolution of any claims against us may result in significant liabilities.

California Department of Toxic Substances Control, DTSC

In September 2002, the Department of Toxic Substances Control (DTSC) inspected Pacific Steel’s (PS) facilities based on an alleged complaint from neighbors due to PS’s excavating to recover scrap metal on its property and on a neighbor’s property, which PS rents from a third party (BNSF Railway). In this same month, DTSC issued an enforcement order of imminent and substantial endangerment determination, which alleges that certain soil piles, soil management and metal recovery operations may cause an imminent and substantial danger to human health and the environment. Consequently, DTSC sanctioned PS for violating the Hazardous Waste Control Laws in the State of California and imposed an obligation to make necessary changes to the location. On July 26, 2004, DTSC filed a Complaint for Civil Penalties and Injunctive Relief against PS in San Diego Superior Court. On July 26, 2004, the court issued a judgment, whereby PS was obligated to pay U.S.$235,000 (Ps. 5 million). This payment was made by PS in 2004 and 2005.

On June 6, 2010 the DTSC and the San Diego Department of Environmental Health (DEH) inspected the facilities of PS, in response to a general complaint. On August 10, 2010 DTSC and DEH conducted a second inspection and found seven infractions. The DEH was satisfied with the compliance of PS on those issues. On October 19, 2010 the technical division of the DTSC recommended to the enforcement division of DTSC that it impose significant penalties upon PS as a result of such infractions. As of December 31, 2018, PS is awaiting a final decision from DTSC.

The land remediation was suspended at the beginning of 2011 due to the inefficiency of the process, which was verified by several studies. As an alternative, once the necessary permits were obtained from the authorities in Mexico, in November 2011, the Mexicali plant began the process of importing raw soil for final disposal in a secure landfill based in Nuevo León, once the metal content was separated, which metal content is used as raw material in the smelting process.

The disposition of a stack estimated at 8,000 tons of material classified RCRA (hazardous for Federal purposes) was also considered for shipment to Mexico. The process began in early 2013, but to date they have not granted permits.

Therefore, on April 9, 2015, a letter from the California Attorney General Department of Justice (Attorney General) was received pursuant to which PS was required, in the absence of obtaining permission from the Mexican authorities, to present a program for transporting the pile of contaminated soil classified as RCRA to an authorized confinement in the United States at the latest on April 22, 2015. This letter warned that PS must ship the stack no later than July 9, 2015, or risk DTSC proceeding with a civil lawsuit seeking the maximum amount of fines established by law and corresponding legal redress.

On April 21, 2015, PS sent a letter to the Attorney General explaining that the authorities in Mexico had not denied permission to the Company but had simply requested that it present its application in a different format, which had already been presented and reviewed by the authority on April 17, 2015.

89 

On July 23, 2015, the Attorney General denied the extension requested by PS and demanded the immediate shipment of the RCRA stack to an authorized landfill. PS began transporting the RCRA soil on July, 29, 2015, and completed removal of the RCRA stack by September 12, 2015 with a total of 3,000 metric tons.

 On January 5, 2016, the Attorney General and PS filed a "final judgment and order on consent" or Consent Judgment in San Diego Superior Court. The parties negotiated the Consent Judgment, which includes the following terms:

● PS must pay US$ 138,000 as a civil penalty for alleged violations of the 2004 Corrective Action Consent Agreement.  PS has made all of the required payments to DTSC as of December 31, 2018.

● PS agreed to remove the RCRA stack and send it to an approved landfill. The Judgment indicates that the Company complied with this commitment by October 2, 2015.

● After removing the RCRA stack, the Company must take samples of the soil in the area where the stack of land was located. Samples were taken and the results indicate that the soil had pollution levels which, although not equal to those of the RCRA stack, exceed the limits set by the State of California. On April 7, 2016, the Attorney General and DTSC demanded that the Company remove the soil 10 feet across and 2 feet deep on the perimeter of the area where the stack of RCRA land was located and dispose of it in an approved confinement. On August 5, 2016, DTSC informed PS that it did not need to remove the soil in the vicinity of the former RCRA stack that exceeds California hazardous waste standards.  Instead, PS and DTSC entered into a Tolling Agreement on August 10, 2016, which tolls for two years (until August 10, 2018) the statute of limitations for DTSC to challenge PS’s compliance with the Consent Judgment.  This Agreement was extended in August 10, 2018, for an additional period of two years, effective December 2018 and ending August 10, 2020.

● PS shall continue to meet the conditions of the final judgment, the corrective measures, and all tasks arising therefrom, which were entered in the same court in 2004. PS is working to develop a “corrective measures study” (CMS) that is intended to develop a plan for determining what remedy will be implemented at the site.  As of December 31, 2018, it is not yet clear what the appropriate remedy will be, when the CMS will be completed, how long remediation will take, and how much it will cost.

As is the case with most steel producers in the United States, we could incur significant costs related to environmental compliance activities and remediation stemming from historical waste management practices or other environmental issues at Republic’s facilities. At December 31, 2018 and 2017, we had a reserve to cover probable environmental liabilities totaling Ps. 51.1 million (U.S.$2.6 million) and Ps. 53.3 million (U.S.$2.7 million), respectively. The reserve includes incremental direct costs of remediation efforts and post remediation monitoring costs that are expected to be included after corrective actions are complete. As of December 31, 2018, the current and non-current portions, Ps. 19.7 million (U.S.$1 million) and Ps. 31.5 million (U.S.$1.6 million), respectively, of the environmental reserve are included in other accrued liabilities and accrued environmental liabilities, respectively, in the accompanying consolidated statement of financial position. The company is not otherwise aware of any material environmental remediation liabilities or contingent liabilities relating to environmental matters with respect to the Republic’s facilities for which the establishment of an additional reserve would be necessary at this time. To the extent the company incurs any such additional future costs, these costs will most likely be incurred over a number of years. However, future regulatory action regarding historical waste management practices at the company’s facilities and future changes in applicable laws and regulations may require the company to incur significant costs that may have a material adverse effect on the company’s future financial performance.

Brasil

On September 5, 2017, Grupo Simec and GV do Brasil were notified of an arbitration procedure brought by SMS Concast before the International Court of Arbitration (ICC), in which the payment of US$1.4 million is requested (Ps.27.6 million), plus additional expenses, for additional costs incurred in the construction and assembly of the steel plant area in Brazil. On November 6, 2017, the Company filed a response, suing SMS Concast for various items that amount to US$5 million (approximately Ps. 98.3 million) approximately. The panel of arbitrators is already constituted and the resolution of the matter is in process.

The tax authorities in Brasil have the right to review the previous five years and could determine differences in taxes payable, plus corresponding adjustments, surcharges and fines.

Item 9. The Offer and Listing

Our series B shares are listed on the Mexican Stock Exchange, and the ADSs are listed on the New York Stock Exchange. On February 20, 2003, we effected a 1 for 20 reverse stock split. On May 30, 2006, we effected a 3 for 1 stock split. To maintain trading prices in the United States, the ADS to share ratio was simultaneously adjusted from one ADS representing one series B share to one ADS representing three Series B shares. The ADSs are evidenced by American depositary receipts, or “ADRs,” issued by The Bank of New York as depositary under a Deposit Agreement, dated as of July 8, 1993, as amended, among us, the depositary and the holders from time to time of ADRs.

(1) On May 30, 2016, the Mexican Stock Exchange announced the suspension in trading of our stock on the Mexican Stock Exchange, identified with the ticker symbol “SIMEC B” as a result of our failure to timely file our 2015 annual report and audited financial statements. We filed our annual report on August 12, 2016 with the Mexican Banking and Securities Commission. The suspension in trading was lifted on August 15, 2016 and our stock is trading normally again on the Mexican Stock Exchange.

Trading on the Mexican Stock Exchange

The Mexican Stock Exchange (Bolsa Mexicana de Valores, S.A.B. de C.V.), located in Mexico City, has been operating continuously since 1907, and is organized as a publicly traded corporation with variable capital stock (sociedad anónima bursátil de capital variable). Securities trading on the Mexican Stock Exchange typically occurs each business day from 8:30 a.m. to 3:00 p.m., Mexico City time.

Since January 1999, all trading on the Mexican Stock Exchange has been effected electronically. The Mexican Stock Exchange may impose a number of measures to promote an orderly and transparent trading price of securities, including the operation of a system of automatic suspension of trading in shares of a particular issuer when price fluctuation exceeds certain limits. The Mexican Stock Exchange may also suspend trading in shares of a particular issuer as a result of:

● non-disclosure of material events; or

● changes in the offer or demand, volume traded, or prevailing share price that are inconsistent with the shares’ historical performance and cannot be explained through publicly available information.

The Mexican Stock Exchange may reinstate trading in suspended shares when it deems that the material events have been adequately disclosed to public investors or when it deems that the issuer has adequately explained the reasons for the changes in supply and demand, volume traded, or prevailing share price. Under current regulations, the Mexican Stock Exchange may consider the measures adopted by the other stock exchanges in order to suspend and/or resume trading in an issuer’s shares in cases where the relevant securities are simultaneously traded on a stock exchange outside of Mexico.

Settlement on the Mexican Stock Exchange is effected two business days after a share transaction. Deferred settlement is not permitted without the approval of the CNBV, even where mutually agreed. Most securities traded on the Mexican Stock Exchange are on deposit with the INDEVAL, a privately owned securities depositary that acts as a clearinghouse, depositary, and custodian, as well as a settlement, transfer, and registration agent for Mexican Stock Exchange transactions, eliminating the need for physical transfer of securities.

Although the Mexican Securities Market Law provides for the existence of an over-the-counter market, no such market for securities in Mexico has developed.

As of 2018, a second stock exchange in Mexico started operations, the Bolsa Institucional de Valores, S.A. de C.V. (BIVA).

Item  10. Additional Information

A. Share Capital

Not applicable.

B. Memorandum and Articles of Association

Our principal objects and purposes, as expressed in the Second Clause of our by-laws, are to engage in the control of companies dedicated to the manufacture, processing and distribution of diversified special bar quality (“SBQ”) steel and structural products.

The Mexican Securities Market Law imposes a duty of care and a duty of loyalty on directors. The duty of care, which generally requires that directors: (i) obtain the information reasonably necessary to make decisions; (ii) request from officers and auditors information that is relevant to a decision to be made; (iii) postpone board of directors meetings when a director is not present, has not arrived on time or has not been provided with the same information as other directors; (iv) deliberate and vote, including if

92 

requested with the presence only of the other directors and the secretary of the board. Directors will breached their duty of care and be subject to liability when damage is caused to the issuer by any of the following: (i) failure to attend board, shareholders’ or committee meetings, which failure prevents such meeting from being duly held; (ii) failure to reveal relevant information to the board of directors or to an applicable committee, subject to legal or contractual limitations on disclosure of such information; or (iii) failure to comply with the duties imposed by the Mexican Securities Market Law or the issuer’s by-laws. Failure of directors to act with due care makes the relevant directors jointly and severally liable for damages and losses caused to the issuer and its subsidiaries, which may be limited in the company’s by-laws or by resolution of the shareholders’ meeting, except in the case of willful misconduct or illegal acts. Liability for breach of the duty of care may also be covered by indemnification provisions and director and executive officer insurance policies.

The duty of loyalty primarily consists of maintaining the confidentiality of information received in connection with the performance of the director’s duties, and abstaining from discussing or voting on matters where the director has a conflict of interest. Directors will have breached their duty of loyalty in the following cases: (i) if without justification they utilize their position to gain benefits for themselves or third parties, including an individual shareholder or group of shareholders; (ii) if they vote on or participate in deliberations concerning an issue on which they have a conflict of interest; (iii) if they do not reveal the conflicts of interests they have; (iv) if they deliberately favor an individual shareholder or group of shareholders to the detriment of others; (v) if they approve related party transactions without observing the related guidelines under the Mexican Securities Market Law; (vi) if they utilize property of the issuer for their own benefit or that of third parties in contravention of relevant policies; (vii) if they make undue use of privileged information; or (viii) if, for themselves or third parties, they take advantage of a corporate opportunity. A violation of the duty of loyalty makes the relevant directors jointly and severally liable for damages and losses caused to the issuer and its subsidiaries, and in every case require removal from their positions. Unlike the duty of care, liability for breach of the duty of loyalty may not be limited by the company’s by-laws, by resolution of the shareholders’ meeting or otherwise, nor may indemnification provisions or insurance policies cover such liability.

Our directors may be subject to criminal penalties of up to 12 years’ imprisonment for certain illegal acts involving willful misconduct that result in losses to us, which include, among others, altering financial statements or records. In terms of the General Law of Commercial Companies and our by-laws, only the shareholders’ meetings can determinate compensation for the directors. Our directors cannot individually exercise any of our borrowing powers. We do not have any retirement plan. Shareholders, or a group of shareholders, that control 10% of our shares can name a director and (in that director’s absence) an alternate director.

Voting Rights and Shareholders’ Meetings

Each series B share entitles its holder to one vote at any meeting of our shareholders. Each series L share would entitle its holder to one vote at any meeting at which holders of series L shares are entitled to vote. Holders of series L shares would be entitled to vote only on the following matters:

● our transformation from one type of corporation to another;

● to elect one member of our board of directors pursuant to the provisions of our by-laws and the Securities Market Law;

● any merger or corporate spin-off in which we are not the surviving entity;

● our dissolution or liquidation;

● cancellation of the registration of our shares with the National Registry of Securities; and

● any action that would prejudice the rights of holders of series L shares and not prejudice the other classes of shares similarly. A resolution on any such action requires the affirmative vote of a majority of all outstanding series L shares.

Shareholders may vote by proxy duly appointed in writing. Under Mexican law, holders of shares of any series are also entitled to vote as a class on any action that would prejudice the rights of holders of shares of such series but not rights of holders of shares of other series, and a holder of shares of such series would be entitled to judicial relief against any such action taken without such a vote. Our board of directors or other party calling for shareholder action initially would determine whether an action requires a class vote on these grounds. A negative determination would be subject to judicial challenge by an affected shareholder, and a court ultimately would determine the necessity for a class vote. There are no other procedures for determining whether a proposed shareholder action requires a class vote, and Mexican law does not provide extensive guidance on the criteria to be applied in making such a determination.

93 

Under Mexican law and our by-laws, we may hold three types of shareholders’ meetings: ordinary, extraordinary and special. Ordinary shareholders’ meetings are those called to discuss any issue not reserved for extraordinary shareholders’ meeting. An annual ordinary shareholders’ meeting must be convened and held within the first four months following the end of each fiscal year to discuss, among other things, the board of director’s report on our financial statements, the chief executive officer’s report on our operations during the preceding year, a report on fulfillment of our tax obligations of the last fiscal year and the Audit Committee’s report with respect to the preceding year, the appointment of members of the board of directors and the chairman of the Audit Committee, declaration of dividends and the determination of compensation for members of the board of directors and for members of the Audit Committee. Under the Mexican Securities Market Law, our ordinary shareholders’ meeting, in addition to those matters described above, will have to approve any transaction representing 20% or more of our consolidated assets, executed in a single or a series of transactions, during any fiscal year.

Extraordinary shareholders’ meetings are those called to consider any of the following matters:

● voluntary dissolution of the company;

● an increase or decrease in a company’s minimum fixed capital;

● change in corporate purpose or nationality;

● any transformation, merger or spin-off involving the company;

● any stock redemption or issuance of preferred stock or bonds;

● the cancellation of the listing of our shares with the National Securities Registry or on any stock exchange;

● any other amendment to our by-laws; and

● any other matters for which applicable Mexican law or our by-laws specifically require an extraordinary meeting.

Special shareholders’ meetings are those that shareholders of the same series or class call and hold to consider any matter particularly affecting the relevant series or class of shares.

Shareholders’ meetings are required to be held in our corporate domicile, which is Guadalajara, Jalisco. Calls for shareholders’ meetings must be made by the chairman or the secretary of the board of directors or the chairman of our Audit Committee. Any shareholder or group of shareholders representing at least 10% of our capital stock has the right to request that the chairman of the board of directors or the chairman of the Audit Committee call a shareholders’ meeting to discuss the matters indicated in the relevant request. If the chairman of the board of directors or the chairman of the Audit Committee fail to call a meeting within 15 calendar days following receipt of the request, the shareholder or group of shareholders representing at least 10% of our capital stock may request that the call be made by a competent court.

Calls for shareholders’ meetings must be published in the official gazette of the state of Jalisco or any major newspaper located in the City of Guadalajara, Jalisco at least 15 calendar days prior to the date of the meeting. Each call must set forth the place, date and time of the meeting and the matters to be addressed. Calls must be signed by whomever makes them, provided that calls made by the board of directors or the Audit Committee must be signed by the chairman, the secretary or a special delegate appointed by the board of directors or the Audit Committee as appropriate, for that purpose. Shareholders’ meetings will be validly held and convened without the need of a prior call or publication whenever all the shares representing our capital are duly represented.

To be admitted to any shareholders’ meeting, shareholders must: (i) be registered in our share registry; and (ii) at least 24 hours prior to the commencement of the meeting submit (a) an admission ticket issued by us for that purpose, and (b) a certificate of deposit of the relevant stock certificates issued by the Secretary or by a securities deposit institution, a Mexican or foreign bank or securities dealer in accordance with the Mexican Securities Market Law. Shareholders may be represented at any shareholders’ meeting by one or more attorneys-in-fact, and these representatives may not be one of our directors. Representation at shareholders’ meetings may be substantiated pursuant to general or special powers of attorney or by a proxy executed before two witnesses.

At or prior to the time of the publication of any call for a shareholders’ meeting, we will provide copies of the publication to the depositary for distribution to the holders of ADSs. Holders of ADSs are entitled to instruct the depositary as to the exercise of voting rights pertaining to the Series B shares. See “Description of American Depository Receipts — Voting Rights.”

94 

Quorum

Ordinary meetings are regarded as legally convened pursuant to a first call when shares representing more than 50% of our capital are present or duly represented. Resolutions at ordinary meetings of shareholders are valid when approved by a majority of the shares present at the meeting. Any number of shares represented at an ordinary meeting of shareholders convened pursuant to a second or subsequent call constitutes a quorum. Resolutions at ordinary meetings of shareholders convened pursuant to a second or subsequent call are valid when a majority of the shares present at the meeting approves them.

Extraordinary shareholders’ meetings are regarded as legally convened pursuant to a first call when shares representing at least 75% of our capital are present or duly represented, and extraordinary shareholders’ meetings convened pursuant to a second or subsequent call are regarded as legally convened when shares representing 50% of our capital are present or duly represented. Resolutions at extraordinary meetings of shareholders are valid when approved by 50% of our outstanding shares. Special meetings of holders of series L shares are governed by the same rules applicable to extraordinary general meeting of holders of series B shares. The quorum for an extraordinary general meeting at which holders of series L shares may not vote is 75% of the series B shares, and the quorum for an extraordinary general meeting at which holders of L shares are entitled to vote is 75% of the outstanding capital stock. Whether on first, second or subsequent call, actions at an extraordinary general meeting generally may be taken by a majority vote of the series B shares outstanding and, on matters which holders of series L shares are entitled to vote, a majority vote of all the outstanding capital stock.

Our by-laws also establish that a delisting of our shares requires the vote of holders of 95% of our capital stock.

No Right of Redemption

The Mexican Securities Market Law and our by-laws provide that our shareholders do not have redemption rights for their shares.

Registration and Transfer

Our shares are registered with the National Securities Registry, as required under the Mexican Securities Market Law and regulations issued by the CNBV. Our shares are evidenced by share certificates in registered form, and registered dividend coupons may be attached thereto. Our shareholders either may hold their shares directly, in the form of physical certificates, or indirectly, in book-entry form, through institutions that have accounts with INDEVAL.

INDEVAL is the holder of record in respect of all such shares held in book-entry form. INDEVAL will issue certificates on behalf of our shareholders upon request. INDEVAL participants, brokers, banks, other financial entities or other entities approved by the CNBV maintain accounts at INDEVAL. We maintain a stock registry and only those persons listed in such stock registry, and those holding certificates issued by INDEVAL indicating ownership, and any relevant INDEVAL participants, will be recognized as our shareholders.

Dividends and Distributions

At the annual general ordinary shareholders’ meeting, the board of directors submits our financial statements for the previous fiscal year, together with their report on us, to the series B shareholders for approval. Under our by-laws and Mexican law, our annual net income, based upon our audited financial statements prepared in accordance with MFRS, is applied as follows: (i) five percent of our net earnings must be allocated to a legal reserve fund, until such fund reaches an amount equal to at least 20% of our then current capital stock, (ii) thereafter, a certain percentage of net earnings may be allocated to any general or specific reserve fund, and (iii) the remainder of any net earnings is allocated as determined by the majority of our shareholders and may be distributed as dividends. All shares that are fully paid and outstanding at the time a dividend or other distribution is declared are entitled to share equally in any or other distribution. We will distribute through INDEVAL cash dividends on shares held through INDEVAL. Any cash dividends on shares evidenced by physical certificates will be paid by surrendering to us the relevant dividend coupon registered in the name of its holder.

To the extent that we declare and pay dividends on our shares, owners of ADSs at the time a dividend or other distribution is declared will be entitled to receive any dividends payable in respect of the series B shares underlying their ADSs, subject to the terms of the Deposit Agreement. Cash dividends will be paid to the depositary in pesos, and, except as otherwise described under “Description of American Depositary Receipts—Dividends, Other Distribution and Rights,” the depositary will convert them into U.S. dollars and pay them to the holders of ADSs net of currency expenses and applicable fees.

A shareholder’s entitlement to uncollected dividends lapses within five years following the stated payment date, in favor of us.

95 

For additional tender offer and insider trading rules applicable to our securities pursuant to Mexican Law, see “Market Information.”

Changes in Capital Stock

Increases and reductions of our share capital must be approved at an ordinary or extraordinary shareholders’ meeting, subject to the provisions of our by-laws and the Mexican Corporations Law.

Subject to the individual ownership limitations set forth in our by-laws, in the event of an increase of our capital stock, other than (i) in connection with mergers, (ii) for the conversion of convertible debentures as provided in Section 210 Bis of the Mexican General Law on Negotiable Instruments and Credit Transactions, (iii) for purposes of conducting a public offering of such shares or (iv) for the resale of shares maintained in our treasury as a result of repurchase of shares conducted on the Mexican Stock Exchange, our shareholders will have a preemptive right to subscribe and pay for new stock issued as a result of such increase in proportion to their shareholder interest at that time. This preemptive right must be exercised by any method provided in Section 132 of the Mexican Corporations Law, by subscription and payment of the relevant stock within fifteen business days after the date of publication of the corresponding notice to our shareholders in the in the official gazette of the state of Jalisco or in one of the newspapers of general circulation in Guadalajara, Jalisco, Mexico, provided that if at the corresponding meeting all of our shares are duly represented, the fifteen business day period shall commence on the date of the meeting. Preemptive rights cannot be waived in advance and cannot be traded separately from the corresponding shares that give rise to such right.

Holders of ADSs may exercise preemptive rights in limited circumstances. See “Description of American Depositary Receipts—Dividends, Other Distributions and Rights.” If a holder of series B shares or ADSs were unable or unwilling to exercise its preemptive rights in connection with such a capital increase, such holder’s proportionate share of dividends and other distributions and voting rights would decline. In addition, depending on the series of shares increased and the pattern in which preemptive rights were exercised, such a capital increase might increase or reduce the portion of our capital stock represented by series B shares and ADSs or increase or reduce the proportionate voting rights of such holder.

Our capital stock may be reduced by resolution of a shareholders’ meeting taken pursuant to the rules applicable to capital increases. Our capital stock also may be reduced upon withdrawal of a shareholder as provided in Section 206 of the Mexican Corporations Law, see “—Voting Rights and Shareholders’ Meetings” above, or by repurchase of our own stock in accordance with the Mexican Securities Market Law, see “Share Repurchases” below.

Share Repurchases

We may choose to acquire our own shares through the Mexican Stock Exchange on the following terms and conditions:

● the acquisition must be carried out through the Mexican Stock Exchange;

● the acquisition must be carried out at market price, unless a public offer or auction has been authorized by the CNBV;

● the acquisition must be carried out against our net worth (capital contable) without adopting a reduction in capital stock or against our capital stock, and the shares so acquired will be held as treasury stock without any requirement to adopt a reduction in capital stock. No shareholder consent is required for such purchases.

● the amount and price paid in all share repurchases must be made public;

● the annual ordinary shareholders meeting must determine the maximum amount of resources to be used in the fiscal year for the repurchase of shares;

● we may not be delinquent on payments due on any outstanding debt issued by us that is registered with the National Securities Registry; and

● any acquisition of shares must be in conformity with the requirements of Article 54 of the Mexican Securities Market Law, and we must maintain a sufficient number of outstanding shares to meet the minimum trading volumes required by the stock markets on which our shares are listed.

The economic and voting rights corresponding to repurchased shares may not be exercised during the period in which we own such shares, and such shares are not deemed to be outstanding for purposes of calculating any quorum or vote at any shareholders’ meeting during such period.

96 

The shares and negotiable instruments representing title to shares belonging to us or, as the case may be, issued but unsubscribed treasury shares, may be placed with the investing public without the need for a shareholders’ meeting or board resolution. As such, the provisions of Article 132 of the Mexican Corporations Law do not apply.

In our Ordinary Shareholders Meeting held on September 14, 2016, an increase in the reserve for repurchase of shares of Ps. 1,000 million was approved and the total reserve at December 31, 2017, amounts to Ps. 2,000 million. In our Ordinary Shareholders

Meeting held on April 23, 2018, an increase in the reserve for repurchase of shares of Ps. 3,000 million was approved and the total reserve at April 23, 2018, amounts to Ps. 5,000 million. In 2015, we repurchased 63,697,541 shares, of which 57,450,890 we resold. At December 31, 2015, we had 11,466,445 treasury shares. In the year 2015 we registered a loss of Ps. 76.3 million in the repurchase of shares. In 2016, we repurchased 36,317,389 shares, and we resold 47,660,950. At December 31, 2016, we had 122,884 treasury shares. In the year 2016 we registered a gain of Ps. 507.7 million in the repurchase of shares. In 2017, we repurchased 5,143,680 shares, and we resold 1,604,000. At December 31, 2017, we had 3,662,564 treasury shares. In the year 2017 we registered a loss of Ps. 22.8 million in the repurchase of shares. In 2018, we repurchased 27,553,643 shares, and we resold 150,000. At December 31, 2018, we had 31,066,207 treasury shares. In the year 2018 we registered a loss of Ps. 4.2 million in the repurchase of shares.

Ownership of Capital Stock by Subsidiaries

Our subsidiaries may not, directly or indirectly, invest in our shares, except for shares acquired as part of an employee stock option plan and in conformity with the Mexican Securities Market Law.

Delisting

Pursuant to the Mexican Securities Market Law, in the event that we decide to cancel the registration of our shares in the National Securities Registry and the listing of our shares on the Mexican Stock Exchange, or if the CNBV orders such cancellation, we will be required to conduct a tender offer for the shares held by minority shareholders and to create a trust with a term of six months, with amounts sufficient to purchase all shares not participating in the tender offer. Under the law, our controlling shareholders will be secondarily liable for these obligations. The price at which the shares must be purchased in the offer must be the greater of (i) the average of the trading price on the Mexican Stock Exchange during the last 30 days on which the shares were quoted prior to the date on which the tender offer is made or (ii) the book value of such shares as determined pursuant to our latest quarterly financial information filed with the CNBV and the Mexican Stock Exchange. If the CNBV orders the cancellation, we must launch the tender offer within 180 days from the date of their request. If we initiate it, under the Mexican Securities Market Law, the cancellation must be approved by 95% of our shareholders.

Other Provisions

Information to Shareholders. The Mexican Corporations Law establishes that companies, acting through their boards of directors, must annually present a report at a shareholder’s meeting that includes:

● a report of the directors on our financial statements, as well as on the policies followed by the directors and on the principal existing projects;

● a report explaining the principal accounting and information policies and criteria followed in the preparation of the financial information;

● a statement of the financial condition of the company at the end of the fiscal year;

● a statement showing the results of operations of the company during the preceding year, as well as changes in the company’s financial condition and capital stock during the preceding year;

● a report of the chief executive officer on the operations of the company during the preceding year;

● a report of the fulfillment of the company’s tax obligations of the last fiscal year;

● a report of the Audit Committee with respect to the preceding year; and

● the notes which are required to complete or clarify the above mentioned information.

97 

In addition to the foregoing, our by-laws provide that our board of directors also should prepare the information referred to above with respect to any subsidiary that represents at least 20% of our net worth (based on the financial statements most recently available).

Shareholders’ Conflict of Interest. Under Mexican law, any shareholder that has a conflict of interest with respect to any transaction must abstain from voting thereon at the relevant shareholders’ meeting. A shareholder that votes on a transaction in which its interest conflicts with ours may be liable for damages in the event the relevant transaction would not have been approved without such shareholder’s vote.

Liquidation. In the event we are liquidated, the surplus assets remaining after payment of all our creditors will be divided among our shareholders in proportion to their respective share holdings. Shares that are only partially paid will participate in the distribution in the proportion that they were paid. The general extraordinary shareholders’ meeting at which the liquidation resolution is made, will appoint one or more liquidators.

Foreign Investment. Ownership by foreign investors of shares of Mexican corporations in certain economic sectors is regulated by the Foreign Investment Law and the regulations thereunder. The Ministry of the Economy and the National Commission on Foreign Investment are responsible for the administration of the Foreign Investment Law and Regulations.

Pursuant to the Mexican Foreign Investment Law and Regulations, foreign investors may acquire up to 100% of the capital stock of Mexican companies or entities in the steel industry. In accordance with our bylaws, Mexican and non-Mexican nationals may own all series of our share capital. We have registered any foreign owner of our shares, and the depositary with respect to the ADSs representing our shares, with the National Registry of Foreign Investment (Registro Nacional de Inversión Extranjera).

Forfeiture of Shares. As required by Mexican law, our by-laws provide that “any alien who at the time of incorporation or at any time thereafter acquires an interest or participation in the capital of the corporation shall be considered, by virtue thereof, as Mexican in respect thereof and shall be deemed to have agreed not to invoke the protection of his own government, under penalty, in case of breach of such agreement, of forfeiture of such interest or participation in favor of the Mexican nation.” Under this provision, a non-Mexican shareholder is deemed to have agreed not to invoke the protection of his own government by asking such government to interpose a diplomatic claim against the Mexican government with respect to the shareholder’s rights as a shareholder but is not deemed to have waived any other rights it may have, including any rights under the U.S. securities laws, with respect to its investment in us. If the shareholder invokes such governmental protection in violation of this agreement, its shares could be forfeited to the Mexican government. Mexican law requires that such a provision be included in the by-laws of all Mexican corporations unless such by-laws prohibit ownership of shares by non-Mexican persons or entities.

Duration. Our existence under our by-laws is indefinite.

Certain Differences between Mexican and U.S. Corporate Law

You should be aware that the Mexican Corporations Law and the Mexican Securities Market Law, which apply to us, differ in certain material respects from laws generally applicable to U.S. corporations and their shareholders.

Independent Directors

The Mexican Securities Market Law requires that 25% of the directors of Mexican public companies must be independent, but the Audit Committee must be comprised entirely of independent directors. One alternate director may be appointed for each principal director, provided that the alternates for the independent directors are also deemed independent. Under Mexican law, certain individuals, including insiders, controlling individuals, major clients and suppliers, and any relatives of such individuals, are per se deemed as non-independent. In addition, under Mexican law, the determination as to the independence of our directors made by our shareholders’ meeting may be contested by the CNBV. The independent directors are required under our bylaws to meet as often as necessary to fulfill their responsibilities. Independent directors are not required under Mexican law or our bylaws to meet without the presence of non-independent directors and management.

Pursuant to the rules and regulations of the New York Stock Exchange, 50% of the directors of listed companies must be independent, and foreign companies subject to reporting requirements under the U.S. federal securities laws and listed on the New York Stock Exchange must maintain an audit committee comprised entirely of independent directors as defined in the United States federal securities laws. Further, independent directors are required meet on a regular basis as often as necessary to fulfill their responsibilities, including at least annually in executive session without the presence of non-independent directors and management.

Audit-Committee

For differences among Mexican Securities Market Law, which apply to us, and laws generally applicable to U.S. corporations regarding audit-committees, see “Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Audit and Corporate Practices Committee.”

Mergers, Consolidations, and Similar Arrangements

A Mexican company may merge with another company only if a majority of the shares representing its outstanding capital stock approve the merger at a duly convened general extraordinary shareholders’ meeting, unless the company’s by-laws impose a

higher threshold. Dissenting shareholders are not entitled to appraisal rights. Creditors have ninety days to oppose a merger judicially, provided they have a legal interest to oppose the merger.

Under Delaware law, with certain exceptions, a merger, consolidation, or sale of all or substantially all the assets of a corporation must be approved by the board of directors and a majority of the outstanding shares entitled to vote thereon. Under Delaware law, a shareholder of a corporation participating in certain major corporate transactions, under certain circumstances, may be entitled to appraisal rights pursuant to which the shareholder may receive payment in the amount of the fair market value of the shares held by the shareholder (as determined by a court) in lieu of the consideration the shareholder would otherwise receive in the transaction. Delaware law also provides that a parent corporation, by resolution of its board of directors and without any shareholder vote, may merge with any subsidiary of which it owns at least 90% of each class of share capital. Upon any such merger, dissenting shareholders of the subsidiary would have appraisal rights.

Anti-Takeover Provisions

Subject to the approval of the CNBV, the Mexican Securities Market Law permits public companies to include anti-takeover provisions in their by-laws that restrict the ability of third parties to acquire control of the company without obtaining approval of the company’s board of directors. See “Market Information—Market Regulation—Anti-Takeover Protections.”

Under Delaware law, corporations can implement shareholder rights plans and other measures, including staggered terms for directors and super-majority voting requirements, to prevent takeover attempts. Delaware law also prohibits a publicly-held Delaware corporation from engaging in a business combination with an interested shareholder for a period of three years after the date of the transaction in which the shareholder became an interested shareholder unless:

● prior to the date of the transaction in which the shareholder became an interested shareholder, the board of directors of the corporation approves either the business combination or the transaction that resulted in the shareholder becoming an interested shareholder;

● upon consummation of the transaction that resulted in the shareholder becoming an interested shareholder, the interested shareholder owns at least 84% of the voting stock of the corporation, excluding shares held by directors, officers, and employee stock plans; or

● at or after the date of the transaction in which the shareholder became an interested shareholder, the business combination is approved by the board of directors and authorized at a shareholders’ meeting by at least 66.67% of the voting stock which is not owned by the interested shareholder.

Shareholders’ Suits

Pursuant to the Mexican Securities Market Law, only a shareholder or group of shareholders holding at least 5% of our outstanding shares may bring a claim against some or all of our directors, secretary of the board of directors or relevant executives for violation of their duty of care or duty of loyalty. In addition, such shareholder or group of shareholders must include in its claim the amount of damages or losses caused to the company and not only the damages or losses caused to the shareholder or group of shareholders bringing the claim, provided that any amount recovered as indemnification arising from the liability action will be for the benefit of the company, and not for the benefit of the shareholder or group of shareholders. The shareholder or group or shareholders must demonstrate the direct and immediate link between the damage or loss caused to the company, and the acts alleged to have caused it. There is no requirement for the shareholder or group of shareholders to hold the shares for a certain period of time in order to bring a claim.

If the court determines that the shareholder or group of shareholders that initiated the claim acted in bad faith, such shareholder or group of shareholders will be liable to pay the legal fees and legal proceeding expenses.

The statute of limitations for these actions is five years from the date on which the act or event that caused the damage or loss occurred. These actions must be brought in the federal or local courts in Guadalajara, Jalisco (Mexico) and the court must personally

99 

notify the parties that have been sued, and must comply with all other legal formalities in order to satisfy the due process requirements of the Mexican Constitution.

Process must be served on the defendant personally, or, in the defendant’s absence, process can be served by a judicial officer on the defendant’s domicile whether or not the defendant is present. A method of service that does not comply with these requirements could be considered void. Class action lawsuits are not permitted under Mexican law.

Shareholder Proposals

Under Mexican law and our by-laws, holders of at least 10% of our outstanding capital stock are entitled to appoint one member of our board of directors.

Delaware law does not include a provision restricting the manner in which nominations for directors may be made by shareholders or the manner in which business may be brought before a meeting.

Calling of Special Shareholders’ Meetings

Under Mexican law and our by-laws, the board of directors, the chairman of the board of directors or the chairman of the Audit Committee may call a shareholders’ meeting. Any shareholder or group of shareholders with voting rights representing at least 10% of our capital stock may request that the chairman of the board of directors or the Audit Committee call a shareholders’ meeting to discuss the matters indicated in the written request. If the chairman of the board of directors or the chairman of the Audit Committee fail to call a meeting within 15 calendar days following date of the written request, the shareholder or group of shareholders may request that a competent court call the meeting. A single shareholder may call a shareholders’ meeting if no meeting has been held for two consecutive years or if matters to be dealt with at an ordinary shareholders’ meeting have not been considered.

Delaware law permits the board of directors or any person who is authorized under a corporation’s certificate of incorporation or by-laws to call a special meeting of shareholders.

Cumulative Voting

Under Mexican law, cumulative voting for the election of directors is permitted.

Under Delaware law, cumulative voting for the election of directors is permitted if expressly authorized in the certificate of incorporation.

Staggered Board of Directors

Mexican law does not permit companies to have a staggered board of directors, while Delaware law does permit corporations to have a staggered board of directors.

Approval of Corporate Matters by Written Consent

Mexican law permits shareholders to take action by unanimous written consent of the holders of all shares entitled to vote. These resolutions have the same legal effect as those adopted in a general or special shareholders’ meeting. The board of directors may also approve matters by unanimous written consent.

Delaware law permits shareholders to take action by written consent of holders of outstanding shares having more than the minimum number of votes necessary to take the action at a shareholders’ meeting at which all voting shares were present and voted.

Amendment of Certificate of Incorporation

Under Mexican law, it is not possible to amend a company’s certificate of incorporation (acta constitutiva). However, the provisions that govern a Mexican company are contained in its by-laws, which may be amended as described below. Under Delaware law, a company’s certificate of incorporation generally may be amended by a vote of holders of a majority of the outstanding stock entitled to vote thereon (unless otherwise provided in the certificate of incorporation), subsequent to a resolution of the board of directors proposing such amendment.

100 

Amendment of By-laws

Under Mexican law, amending a company’s by-laws requires shareholder approval at an extraordinary shareholders’ meeting. Mexican law requires that at least 75% of the shares representing a company’s outstanding capital stock be present at the meeting in the first call (unless the by-laws require a higher threshold) and that the resolutions be approved by a majority of the shares representing a company’s outstanding capital stock.

Under Delaware law, holders of a majority of the outstanding stock entitled to vote and, if so provided in the certificate of incorporation, the directors of the corporation, have the power to adopt, amend, and repeal the by-laws of a corporation.

C. Material Contracts

None

D. Exchange Control

There are no legislative or legal provisions currently in force in Mexico or arising under our by-laws restricting the payment of dividends to holders of our common stock not resident in Mexico, except for regulations restricting the remittance of dividends and other payments in compliance with United Nations sanctions. There are no limitations, either under the laws of Mexico or in our by-laws, on the right of foreigners to hold or vote on shares of our common stock.

E. Taxation

The following summary contains a description of the material anticipated U.S. and Mexican federal income tax consequences of the purchase, ownership and disposition of the series B shares or ADSs by a “non-Mexican holder” (as defined below) that is an individual citizen or resident of the United States or a U.S. domestic corporation or that otherwise will be subject to U.S. federal income tax on a net income basis in respect of the series B shares or ADSs (a “U.S. holder”), but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to an owner of the series B shares or ADSs. In particular, the summary deals only with U.S. holders that will hold the series B shares or ADSs as capital assets and use the U.S. dollar as their functional currency and does not address the tax treatment of a U.S. holder that owns or is treated as owning 10% or more of our outstanding voting shares. In addition, the summary does not address the effects of the U.S. Medicare tax on net investment income, or any U.S. or Mexican state or local tax considerations that may be relevant to U.S. holders. This summary also does not address U.S. federal income tax consequences applicable to U.S. holders that are subject to special tax rules, such as banks, securities or currency dealers, traders in securities that mark their securities to market, insurance companies, tax-exempt entities, persons liable for the alternative minimum tax, persons that hold ADSs or series B shares as a hedge or as part of a straddle, conversion transaction or other risk reduction transaction for tax purposes or partnerships or other pass-through entities for U.S. federal income tax purposes. If a partnership (or other pass-through entity for U.S. federal income tax purposes) holds the series B shares or ADSs, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If a U.S. holder is a partner of a partnership holding our series B shares or ADSs, such U.S. holder should consult its tax advisor.

The summary is based upon the federal income tax laws of the United States and Mexico as in effect on the date of this annual report, including the provisions of the income tax treaty between the United States and Mexico and protocol thereto (the “Tax Treaty”), all of which are subject to change, possibly with retroactive effect in the case of U.S. federal income tax law. Prospective investors in the series B shares or ADSs should consult their own tax advisors as to the U.S., Mexican or other tax consequences of the purchase, ownership and disposition of the series B shares or ADSs, including, in particular, the effect of any foreign, state or local tax laws and their entitlement to the benefits, if any, afforded by the Tax Treaty.

For purposes of this summary, the term “non-Mexican holder” shall mean a holder of series B shares or ADSs that is not a resident of Mexico and that will not hold the series B shares or ADSs or a beneficial interest therein in connection with the conduct of a trade or business through a permanent establishment or fixed base in Mexico.

An individual is a resident of Mexico for tax purposes if he established his residence in Mexico. When the individual in question has a residence in another country, the individual will be deemed a resident in Mexico if his “center of vital interests” is located in Mexico. This will be deemed to occur if (i) more than 50% of the aggregate income realized by such individual in the calendar year is from a Mexican source or (ii) the principal center of his professional activities is located in Mexico.

A Mexican national who files a change of tax residence notice with a country or jurisdiction that does not have a comprehensive exchange of information agreement with Mexico and in which his income is subject to a preferred tax regime pursuant to the provisions of the Mexican Income Tax Law will be considered a Mexican resident for tax purposes during the year the notice is filed and during the following three years. Unless otherwise proven, a Mexican national is deemed a resident of Mexico for tax purposes.

101 

An entity in Mexico is a resident of Mexico if it maintains its principal place of business or its place of effective management in Mexico. If non-residents of Mexico are deemed to have a permanent establishment in Mexico for tax purposes, all income attributable to the permanent establishment will be subject to Mexican taxes, in accordance with applicable Mexican tax law.

In general, for U.S. federal income tax purposes, holders of ADSs will be treated as the beneficial owners of the series B shares represented by those ADSs.

Taxation of Dividends

Mexican Tax Considerations

Under Mexican Income Tax Law provisions (Ley del Impuesto Sobre la Renta), dividends paid to non-Mexican holders with respect to the series B shares (including the shares represented by the ADSs) are not subject to Mexican withholding tax.

Dividends paid from distributable earnings that have not been subject to corporate income tax are subject to a corporate-level dividend tax at a rate of 42.86% for 2018. The corporate-level dividend tax on the distribution of earnings is not final and may be credited against income tax payable during the fiscal year in which the dividend tax was paid and for the following two years. Dividends paid from distributable earnings, after corporate income tax has been paid with respect to these earnings, are not subject to this corporate-level dividend tax. Currently, dividend distributions are not subject to individual withholding taxes for shareholder recipients thereof.

Dividends or profits distributed by legal entities resident in Mexico that are paid to natural persons and persons residing abroad on profits generated since fiscal year 2014, are subject to an additional Income Tax rate of 10%; this additional tax will be withheld by the legal person who distributes the dividend and its payment is considered definitive. In this case, the rates established in the agreement to avoid double taxation between Mexico and the United States of America can be applied.

Distributions made by us to our shareholders other than as dividends, including capital reductions, amortization of shares or otherwise, would be subject to taxation in Mexico at the corporate rate of 30% in 2018, or at the rate mentioned above, as the case may be.

U.S. Federal Income Tax Considerations

The gross amount of any distributions paid with respect to the series B shares or the ADSs (including any amounts withheld for Mexican taxes), to the extent paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes, will be taxable as dividends and generally will be includible in the gross income of a U.S. holder as ordinary income on the date on which the distributions are received by the U.S. holder, in the case of series B shares, or the depositary, in the case of ADSs. Such dividends will not be eligible for the dividends received deduction allowed to certain corporations under the U.S. Internal Revenue Code of 1986, as amended. Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by non-corporate U.S. holders (including individuals) with respect to the series B shares and ADSs will be subject to taxation at a maximum rate of 20% if the dividends are “qualified dividends.” Dividends paid on the series B shares and ADSs will generally be treated as qualified dividends if (A) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company (“PFIC”) and (B) (i) we are eligible for the benefits of a comprehensive income tax treaty with the United States that the Internal Revenue Service has approved for the purposes of the qualified dividend rules or (ii) the series B shares or ADSs, as applicable, are readily tradable on an established securities market in the United States. The Tax Treaty has been approved for the purposes of the qualified dividend rules and we believe that we are eligible for the benefits of the Tax Treaty. Further, as discussed below, we do not believe that we are a PFIC. Therefore, we believe that dividends paid to a non-corporate U.S. holder with respect to the series B shares and ADSs will generally be treated as qualified dividends. U.S. holders should consult their own tax advisors in this regard in light of their particular circumstances.

To the extent that a distribution exceeds our current and accumulated earnings and profits for a taxable year, it generally will first be treated as a non-taxable return of basis to the extent thereof, and thereafter as capital gain from the sale of the series B shares or ADSs. However, we do not expect to keep earnings and profits in accordance with U.S. federal income tax principles. Therefore, a U.S. holder should expect that a distribution will generally be treated as a dividend (as discussed above).

Distributions, which will be made in pesos, will be includible in the income of a U.S. holder in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date they are received by such U.S. holder, in the case of series B shares, or by the depositary, in the case of ADSs, whether or not they are converted into U.S. dollars. If the pesos received as a dividend are converted into U.S. dollars on the date they are received, a U.S. holder generally will not be required to recognize foreign currency gain or loss in respect of the dividend income. If the pesos received as a dividend are not converted into U.S. dollars on the date of receipt, you will have a basis in the pesos equal to their United States dollar value on the date of receipt. U.S. holders should consult

102 

their own tax advisors regarding the treatment of foreign currency gain or loss, if any, on any pesos received that are converted into U.S. dollars on a date subsequent to receipt.

Subject to certain conditions and limitations (including a minimum holding period requirement), Mexican withholding taxes on dividends, if any, may be treated as foreign taxes eligible for credit against a U.S. holder’s U.S. federal income tax liability. Dividend income generally will constitute foreign source “passive category income” or, in the case of certain U.S. holders, “general category income” for U.S. foreign tax credit purposes.

Distributions of additional series B shares or ADSs that are made as part of a pro rata distribution to all our stockholders generally will not be subject to U.S. federal income tax.

Taxation of Dispositions of Shares or ADSs

Mexican Tax Considerations

Gain on the sale or other disposition of ADSs by a U.S. holder will generally not be subject to Mexican tax. Deposits and withdrawals of series B shares in exchange for ADSs will not give rise to Mexican tax or transfer duties.

Gain on the sale of series B shares by a U.S. holder will not be subject to any Mexican tax if the transaction is carried out through the Mexican Stock Exchange or other stock exchange or securities markets approved by the Mexican Ministry of Finance and Public Credit. Gain on sales or other dispositions of series B shares made in other circumstances generally would be subject to Mexican tax at a rate of 30% for 2018 of gains realized from the disposition.

Under the Tax Treaty, a U.S. holder that is eligible to claim the benefits of the Tax Treaty will be exempt from Mexican tax on gains realized on a sale or other disposition of series B shares in a transaction that is not carried out through the Mexican Stock Exchange or such other approved securities markets, so long as the holder did not own, directly or indirectly, 25% or more of our share capital (including ADSs) during the twelve-month period preceding the sale or other disposition, and the value of those shares does not derive mainly from immovable property located in Mexico. Specific formalities apply to claim such treaty benefits.

U.S. Federal Income Tax Considerations

Upon the sale or other disposition of the series B shares or ADSs, a U.S. holder generally will recognize U.S. source capital gain or loss in an amount equal to the difference between the amount realized on the sale or other disposition and such U.S. holder’s tax basis in the series B shares or ADSs. Gain or loss recognized by a U.S. holder on such sale or other disposition generally will be long-term capital gain or loss if, at the time of the sale or other disposition, the series B shares or ADSs have been held for more than one year. Under current law, long-term capital gain recognized by a non-corporate U.S. holder (including individuals) generally is subject to a maximum federal income tax rate of 20%. The deduction of a capital loss is subject to limitations for U.S. federal income tax purposes. Deposits and withdrawals of series B shares by U.S. holders in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes.

A U.S. holder that receives pesos upon sale or other disposition of the series B shares will realize an amount equal to the U.S. dollar value of the pesos upon the date of sale (or in the case of cash basis and electing accrual basis taxpayers, the settlement date). A U.S. holder will have a tax basis in the pesos received equal to the U.S. dollar value of the pesos received translated at the same rate the U.S. holder used to determine the amount realized on its disposal of the series B shares. Any gain or loss realized by a U.S. holder on a subsequent conversion of the pesos into U.S. dollars generally will be a U.S. source ordinary income or loss.

Other Mexican Taxes

There are no Mexican inheritance, gift, succession or value added taxes applicable to the ownership, transfer or disposition of the series B shares or ADSs by non-Mexican holders; provided, however, that gratuitous transfers of the series B shares or ADSs may in certain circumstances cause a Mexican federal tax to be imposed upon the recipient. There are no Mexican stamp, issue, registration or similar taxes or duties payable by non-Mexican holders of the series B shares or ADSs.

Passive Foreign Investment Company (PFIC)

Based on our audited financial statements and relevant market and shareholder data, we believe that we are not a PFIC for U.S. federal income tax purposes with respect to our 2016, 2017 and 2018 taxable years, and we expect to operate in such a manner so as to not become a PFIC. If, however, we are or become a PFIC, a U.S. holder could be subject to additional U.S. federal income taxes on gain recognized with respect to the series B shares or ADSs and on certain distributions, plus an interest charge on certain taxes treated as having been deferred under the PFIC rules.

103 

U.S. Backup Withholding Tax and Information Reporting Requirements

In general, information reporting requirements will apply to certain payments to a U.S. holder of dividends in respect of the series B shares or ADSs or the proceeds received on the sale or other disposition of the series B shares or ADSs that are paid to such U.S. holder within the United States (and in certain cases, outside the United States), unless such U.S. holder is an exempt recipient. A backup withholding tax may apply to such amounts if the U.S. holder fails to provide an accurate taxpayer identification number to the paying agent or fails to establish an exemption or otherwise comply with these provisions. Amounts withheld as backup withholding tax will be creditable against the U.S. holder’s U.S. federal income tax liability and may entitle the U.S. holder to a refund, provided that the required information is furnished to the U.S. Internal Revenue Service.

H. Documents on Display

Statements contained in this annual report regarding the contents of any contract or other document are not necessarily complete, and, where the contract or other document is an exhibit to the annual report, each of these statements is qualified in all respects by the provisions of the actual contract or other documents.

We are subject to the informational requirements of the U.S. Securities Exchange Act of 1934, or the Exchange Act. Accordingly, we file reports and other information with the Commission, including annual reports on Form 20-F and reports on Form 6-K. You may inspect and copy the reports and other information that we file with the Commission at the public reference facilities of the Commission at 100 F. Street, N.E., Washington D.C. 20549.

In addition, the Commission maintains an internet website at www.sec.gov from which you can electronically access this annual report and the other materials that we file with the Commission.

As a foreign private issuer, we are not subject to the same disclosure requirements as a domestic U.S. registrant under the Exchange Act. For example, we are not required to prepare and issue quarterly reports. However, we are required to file with the Commission, promptly after it is made public or filed, information that we make public in Mexico, file with the Mexican Stock Exchange or the CNBV or distribute to our security holders. As a foreign private issuer, we are exempt from Exchange Act rules regarding proxy statements and short-swing profits.

I. Subsidiary Information

Not applicable.

Item 11.  Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk, which is the potential risk of loss in fair values, cash flows or earnings due to changes in interest rates and foreign currency rates (primarily the peso/dollar exchange rate), as a result of our holdings of financial instrument positions. Our financial instruments include cash and cash equivalents, trade and other accounts receivable, accounts payable, long-term debt securities and related party debt. We do not maintain a trading portfolio. Our borrowings are entirely denominated in U.S. dollars. We do not utilize derivative financial instruments to manage our market risks with respect to our financial instruments. Historically, based on the last ten years of data, inflation in Mexico has been 7.7% higher than the Mexican peso’s devaluation relative to the dollar.

We are exposed to market risk due to fluctuations of the purchase price of natural gas. To limit our exposure, we use derivative financial instruments, which currently consist of natural gas swap contracts. These contracts are recognized on our balance sheet at fair value. The swaps are considered as cash flow hedges since the cash flow exchanges under the swap are highly effective in mitigating exposure to natural gas price fluctuations. The change in fair value of the swaps is recorded as part of comprehensive income in stockholders’ equity for those contracts that are designated as accounting hedges until such time as the related item hedged is recorded in income. At that time, the hedging instrument’s fair value is recorded in income. For those contracts that are not

104 

designated as accounting hedges, the change in fair value is recorded directly into income. We do not believe our market risk with respect to these natural gas futures contracts is material. At December 31, 2018 and 2017 we did not have natural gas cash-flow exchange contracts or swaps.

Market Risk Measurement

We measure our market risk related to our financial instruments based on changes in interest rates and foreign currency rates utilizing a sensitivity analysis. The sensitivity analysis measures the potential loss in fair values, cash flows and earnings based on a hypothetical increase in interest rates and a decline in the peso/dollar exchange rate. We used market rates as of December 31, 2018 on our financial instruments to perform the sensitivity analysis. We believe that these potential changes in market rates are reasonably possible in the near-term (one year or less). Based upon our analysis of the impact of a 100 basis point increase in interest rates and a 10% decline in the peso/dollar exchange rate, we have determined that such increase in interest rates and such decline in the peso/dollar exchange rate would not have a material adverse effect on our earnings. Because there is no active trading market for our debt instruments, we are not able to determine the impact of these changes on the fair value of those debt instruments. The sections below describe our exposure to interest rates and currency rates including the impact of changes in these rates on our earnings.

Interest Rate Exposure

We are exposed to changes in short-term interest rates as we invest in short-term dollar-denominated interest bearing investments. On the liability side, we utilize fixed rate debt, and our financial debt was less than US$1 million as of December 31, 2018. The floating rate debt is exposed to changes in interest expense and cash flows from changes in LIBOR, while the fixed rate debt is mostly exposed to changes in fair value from changes in medium term interest rates. Based on an immediate 100 basis point rise in interest rates, we estimate that our earnings before taxes would not be significantly affected.

Currency Rate Exposure

Our primary foreign currency exchange rate exposure relates to our debt securities as well as our dollar-denominated trade payables. Our principal currency exposure is to changes in the peso/dollar exchange rate. We estimate that a 10% decline in the peso/dollar exchange rate would result in a decrease in our earnings before taxes of approximately Ps. 0.6 million (U.S.$0.03 million).

The sensitivity analysis is an estimate and should not be viewed as predictive of our future financial performance. Additionally, we cannot assure that our actual losses in any particular year will not exceed the amounts indicated above. However, we do believe that these amounts are reasonable based on the financial instrument portfolio at December 31, 2018 and assuming that the hypothetical market rate changes selected by us in our market risk analysis occur during 2019. The sensitivity analysis does not give effect to the impact of inflation on its exposure to increases in interest rates or the decline in the peso/dollar exchange rate.

Item 12.  Description of Securities Other than Equity Securities

A. Debt Securities

Not applicable.

B. Warrants and Rights

Not applicable

C. Other Securities

Not applicable

D. American Depositary Shares

12.D.3. American Depositary Shares

The Bank of New York Mellon serves as the depositary for our ADSs. The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deductions from cash distributions or by directly billing investors or by charging the book-entry system

105 

accounts of participants acting for them. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

ADS holders are also required to pay additional fees for certain services provided by the depositary, as set forth in the table below.

Depositary service	Fee payable by ADR holders
Issuance and delivery of ADSs, including issuances resulting from a distribution of shares or rights or other property	Up to U.S.$5.00 per 100 ADSs (or portion thereof)
Cancellation of ADSs for the purpose of withdrawal, including if the deposit agreement terminates	Up to U.S.$5.00 per 100 ADSs (or portion thereof)
Distribution of securities distributed to holders of deposited securities which are distributed by the depositary to ADS registered holders	A fee equivalent to the fee that would be payable if securities distributed to you had been shares and the shares had been deposited for issuance of ADSs
Registration for the transfer of shares	Registration or transfer fees that may from time to time be in effect
Cash distribution fees	U.S.$0.02 or less per ADS
Depositary services	U.S.$0.02 or less per ADS

In addition, holders may be required to pay a fee for the distribution or sale of securities. Such fee (which may be deducted from such proceeds) would be for an amount equal to the lesser of (1) the fee for the issuance of ADSs that would be charged as if the securities were treated as deposited shares and (2) the amount of such proceeds.

12.D.4 Direct And Indirect Payments By The Depositary

Fees Incurred in Past Annual Period

We did not receive any reimbursement from the depositary in 2018, 2017 or 2016.

Fees to be Paid in the Future

The Bank of New York Mellon, as depositary, has agreed to reimburse us for expenses they incur that are related to establishment and maintenance expenses of the ADS program. The depositary has agreed to reimburse us for its continuing annual stock exchange listing fees. The depositary has also agreed to pay the standard out-of-pocket maintenance costs for the ADSs, which consist of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend checks, electronic filing of U.S. Federal tax information, mailing required tax forms, stationery, postage, facsimile, and telephone calls. It has also agreed to reimburse us annually for certain investor relationship programs or special investor relations promotional activities. In certain instances, the depositary has agreed to provide additional payments to us based on any applicable performance indicators relating to the ADS facility. There are limits on the amount of expenses for which the depositary will reimburse us, but the amount of reimbursement available to us is not necessarily tied to the amount of fees the depositary collects from investors.

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

Item 15.  Controls and Procedures

A. Disclosure Control and Procedures

Our principal executive officer and our principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this annual report, have concluded that, as of such date, our disclosure controls and procedures were not effective, in light of the material weaknesses in our internal control over financial reporting discussed below.

B. Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Our internal control system is designed to provide reasonable assurance as to the reliability of the published financial statements under applicable International Financial Reporting Standards. 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 assurances with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness of the internal control over financial reporting 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 decline.

The effectiveness of our internal control over financial reporting as of December 31, 2018 has been audited by Marcelo de los Santos, S.C., a practice member of Moore Stephens International Limited, independent registered public accounting firm, as stated in their report which appears in Item 15.C as required by item 15.B(4) of Form 20-F.

Our management was able to assess the effectiveness of our internal control over financial reporting as of December 31, 2018. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013) in Internal Control – Integrated Framework. Based on its assessment and those criteria, our management identified the following material weaknesses in our internal control over financial reporting, and therefore determined that our internal controls over financing reporting were not effective at December 31, 2018.

Material Weaknesses

A deficiency in internal control over financial reporting exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. A significant deficiency is a deficiency, or a combination of deficiencies, in internal control over financial reporting that is less severe than a material weakness, yet important enough to merit attention by those responsible for the oversight of the company’s financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Fiscal Year Ended December 31, 2014

In our assessment of our internal controls over financial reporting for the year ended December 31, 2014, the following material weaknesses were identified:

● Insufficient resources applied to the remediation and appropriate monitoring of internal control weaknesses, most of which were identified in previous years and continue to be unresolved.

● Inadequate distribution and segregation of duties within the accounting department in the Mexican Subsidiaries due to insufficient resources. Additionally, the internal audit staff was reduced and considered insufficient to fulfill their role.

● Significant deficiencies were detected regarding entity-level controls and control environment which, in the aggregate, constitute a material weakness, and which include: (i) inadequate controls for the definition, review and approval process of the disclosure in the financial statements and our annual report on form 20-F, (ii) non-operating and outdated whistleblower line for the Mexican subsidiaries, (iii) ineffective controls in our patents registry, (iv) deficient distribution of our code of ethics to employees and officers and poor promotion of strong control environment and internal controls in accordance with the COSO model, (v) failure to integrate all control processes into one Enterprise Resource Planning (ERP) system, (vi) lack of an accounting manual with accounting instructions on most of accounting records, (vii) lack of specific procedures for the approval of transactions with related parties, (viii) failure to create and implement a complete training plan for management personnel preparing financial records, (ix) limited IFRS and consolidation process understanding and reduced personnel within our Internal Audit

107 

department which limited the scope of the management assessment; the internal audit plan was not carried out in full and did not include tests about risk assessment, including environmental, fraud, compliance with laws and review of the consolidated financial statements; (x) lack of committees to review, approve and make risk assessments of all our contracts, and (xii) informal communications of deficiencies and remediation plan to the areas and managers involved.

● Inadequate supervision and controls within the accounting department which impacted the financial statement closing process, conversion of foreign subsidiaries and intercompany reconciliations, resulting in material accounting errors.

● A lack of an appropriate consolidation system to allow management to properly supervise the preparation of consolidated financial information with the detail required.

● SimRep did not maintain effective controls relating to accounting of certain capital expenditures and related fixed assets were found. Lastly, the evaluation for impairments is not reasonable given actual results of such Subsidiary.

● Significant deficiencies were also detected at our subsidiary Corporación Aceros DM, S.A. de C.V. which in the aggregate, constitute a material weakness. These significant deficiencies include (i) ineffective controls and insufficient supporting documentation for closings of periods end and financial statements review and authorization; the related procedures were incomplete and do not include specific procedures to enter transactions into the general ledger, to select and apply accounting policies and have not been updated in the last 3 years, which such controls are necessary to give reasonable assurance of compliance with IFRS, (ii) no evidence of review of some account balances, such as fixed assets, sales and tax calculations by the responsible individuals; there is also no evidence of review of the financial statements by the General Manager of Corporación Aceros DM, S.A de C.V., (iii) undocumented processes and deficient controls in the access to the information systems, (iv) deficient controls to review and approve cost calculations of finish goods, period end costs and inventories and cost of sales report, (v) lack of physical inventory of fixed assets in several years; and (vi) failure to document and communicate adequately responsibilities and authority of key financial roles.

Fiscal Year Ended December 31, 2015

Our management did not assess the effectiveness of our internal controls over financial reporting as of December 31, 2015. The internal audit department did not develop its functions to comply with the analysis of the controls during 2015. Consequently, this limited the functions of the Audit Committee.

Our external auditors, in their Attestation Report for the year ended December 31, 2015, identified the following material weaknesses:

● Insufficient resources applied to the remediation and appropriate monitoring of internal control weaknesses, most of which were identified in previous years and continue to be unresolved.

● Inadequate distribution and segregation of duties within the accounting department in our Subsidiaries due to insufficient resources. Additionally, the internal audit staff was considered insufficient to fulfill their role.

● Significant deficiencies were detected regarding entity-level controls and control environment which, in the aggregate, constitute a material weakness and create a reasonable likelihood that a material misstatement of our annual and interim financial statements will not be prevented or detected on a timely basis. Such deficiencies include: (i) inadequate controls for the definition, review and approval process of the disclosure in the financial statements and our annual report on form 20-F, (ii) whistleblower line for our Mexican subsidiaries was not fully operational, our website information is outdated and does not include information about our Brazilian operations, (iii) ineffective controls in our patents registry, (iv) deficient distribution of our code of ethics to employees and officers and poor promotion of strong control environment and internal controls in accordance with the COSO model, (v) failure to integrate all control processes into one Enterprise Resource Planning (ERP) system, (vi) lack of an accounting manual with accounting instructions on most of accounting records, (vii) lack of specific procedures for the approval of transactions with related parties, (viii) failure to create and implement a complete training plan for management personnel preparing financial records under IFRS, (ix) limited IFRS and consolidation process understanding and reduced personnel within our Internal Audit department which limited the scope; also the internal audit plan was not carried out, and therefore the audit department did not perform risk assessment and environmental, fraud, compliance with laws, review of the consolidated financial statements and review of our annual report on form 20-F; (x) lack of committees to review, approve and make risk assessments of all our contracts; and (xi) informal communications of deficiencies and remediation plan to the areas and managers

108 

involved.

● Inadequate supervision and controls within the accounting department which impacted the financial statement closing process, conversion of foreign subsidiaries, intercompany reconciliations and a lack of controls for the issuance and authorizations of journal entries, resulting in material accounting errors.

● A lack of an appropriate consolidation system to allow management to properly supervise the preparation of consolidated financial information with the detail required.

● SimRep did not maintain personnel with the appropriate level of knowledge and experience of accounting and training required to comply with financial reporting requirements. This material weakness led to the certain control deficiencies, each of which are considered to be a material weakness. See Item 15.C “Attestation Report of the Independent Registered Public Accounting Firms.”

● Failure to provide our external auditors with evidence of the evaluation of the effectiveness of internal controls in our Brazilian subsidiary, in addition of not hiring an external auditor for this evaluation.

● Significant deficiencies were also detected at our subsidiary Corporación Aceros DM, S.A. de C.V. which in the aggregate, constitute a material weakness. See Item 15.C “Attestation Report of the Independent Registered Public Accounting Firms.”

Fiscal Year Ended December 31, 2016

● In our assessment of our internal controls over financial reporting for the year ended December 31, 2016, the following material weaknesses were identified: Regarding the control environment and entity level controls, the following material weaknesses were identified: (i) lack of a whistleblower tool that covers the entirety of the company; (ii) regarding the distribution of the code of ethics, certain sectors of the employees did not recognize the code of ethics; (iii) ineffective control of the patent registration process, which lacks a policy and a procedure; (iv) lack of a policy and procedure for the valuation of assets and the company’s physical inventories; (v) lack of a policy and procedure governing the extensions of credit to the clients; (vi) lack of a policy and procedure for the registration of related parties and the approval of transactions with related parties.

● Lack of an appropriate consolidation system to allow management to properly supervise the preparation of consolidated financial information with the detail required.

● In connection with certain financial reporting processes, lack of a robust role-segregation model for the creation, editing, deletion, display only, and modification of such processes.

● Lack of communication between the internal audit team, which impacted time of test execution, leaving out of scope cycles such as income, human resources, general controls of information technology and costs and inventories.

● Lack of documentation setting out the procedure in the event of a disaster (Disaster Recovery Plan) and documentation setting out the procedure in order to continue the operations of the business (Business Continuity Plan).

Fiscal Year Ended December 31, 2017.

In our assessment of our internal controls over financial reporting for the year ended December 31, 2017, the following material weaknesses were identified:

· Insufficient training on, and knowledge of, COSO and the related operation of the control environment for mid-level personnel of the Company.

· A lack of a formalized policy related to the delegation of authority clearly defining the roles and responsibilities for employees.

109 

· The Company lacks a system of assessing and monitoring employee performance to increase their skills to be prepared for the complexity of the Company´s operation.

· The Company does not maintain a detailed accounting manual and closing checklists. The lack of such procedures reduces the likelihood of detecting errors on a timely basis during the financial close. Similarly, there is a lack of documents supporting the existence of supervisory review over accounting entries recorded by the Company.

· The Company does not maintain appropriate evidence over records supporting certain matters in regards to fixed assets:

· There is insufficient data to support certain adjustments to fixed assets recorded on the books of the Company.

· The Company does not have an appropriate system to properly store records in regards to significant acquisitions of fixed assets.

· The Company failed to reconcile their recorded fixed assets to the underlying support.

· The Company did not document appropriate authorizations in regards to capital investments or to increases in the planned size of an ongoing investment project.

· The Company has neither a system of tagging and tracking fixed assets nor a process for taking periodic inventories to determine the continued existence of recorded fixed assets.

· The Company lacks sufficient documentation and internal controls related to the process of obtaining credit. The Company also lacks sufficient training for personnel responsible for monitoring such credit facilities in regards to fraud detection and ongoing compliance matters.

· The Company lacks a program to ascertain that the administrative staff with access to accounting records are sufficiently trained and monitored.

· The Company lacks an appropriate environment to ensure that the financial records are closed in accordance with International Financial Reporting Standards properly and in a timely manner. Items identified included:

o A lack of appropriate accounting resources at the corporate level which adversely impacted the operation of key supervision controls over the accounting department, the financial statement closing process, and the process of computing and authorizing journal entries.

o A lack of appropriate procedures to analyze the results of the business units prior to consolidation.

o A lack of a unified computerized general ledger or enterprise resource planning system among the business units. There is also a lack of a common chart of accounts which would simplify the consolidation process.

110 

o A lack of an appropriate consolidation system allowing management to properly supervise the preparation of consolidated financial information. The system is highly manual, increasing the risk of human error and lacking sufficient oversight as the process is largely performed by a single member of the accounting staff.

· An audit performed on the information technology systems of the Company determined that approximately 25% of controls over the information technology infrastructure were either deficient in design or missing. Additional findings include:

o A lack of an internal reference framework methodology to ascertain and assess information technology risks.

o The lack of a methodology to evaluate the design and operational effectiveness of key controls over critical business processes.

o No system of verification of the access profiles of personnel or a process to verify that accounts of former employees are properly closed.

· In the case of GV do Brasil Indústria e Comércio de Aḉo Ltda in Brasil we observed an inadequate segregation of duties, in respect to system access and activities related to:

o The person with final responsibility for the preparation of the financial reports is also responsible for the corporate tax area, financial management (approval of payments and receipts, analysis of client credit risks including credit limits still not established, and negotiations with clients), monthly calculation of the costs of the products sold (and, consequently, of the value of the inventories of finished products), and assessment of the amount of physical impurities contained in scrap inventories, which also determines the valuation.

o The person responsible for supervising the physical movements of raw materials and finished products also has the following duties: authorization to issue sales invoices, the authority to adjustment quantities of inventory items, and also responsibility for planning and authorizing the movements of the physical inventory of between inventory locations.

· In the case of SimRep Corporation and Subsidiaries in the United States we identified that as a component of the financial control process, certain accounts are not being reconciled quarterly to the underlying details and the components of certain other accounts are not being reviewed by management.

· In the case of SimRep Corporation and Subsidiaries in the United States we identified that a control requiring the signatures of the vice-president of Finance, head of information technology and the General Manager to authorize all expenditures over $25,000 was not operating effectively. A number of the purchases lacked the required supporting signatures.

· In the case of SimRep Corporation and Subsidiaries in the United States we identified that the controller at one of the production plants failed to properly perform all required tests to review the inventories to be sure they are properly recorded at the lower of cost or market, and also failed to obtain approval for a journal entry which should be generated from the analysis.

111 

Fiscal Year Ended December 31, 2018. In our assessment of our internal controls over financial reporting for the year ended December 31, 2018, the following material weaknesses were identified:

· Transactions with related parties:

o Lack of evidence of how transactions with third parties are documented and authorized.

o Lack of policy regulating the way in which transactions with third parties should be documented and authorized.

· Information Technology Systems:

o Lack of backup-generation controls for computer equipment that contains key company information.

o Insufficient Information Technology infrastructure to support the Company’s growth when required.

C.    Attestation Report of the Independent Registered Public Accounting Firms

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and
Stockholders of Grupo Simec, S.A.B. de C.V.

Opinion on Internal Control over Financial Reporting

We have audited Grupo Simec, S.A.B. de C.V. (the Company´s) internal control financial reporting as of December 31, 2018, based on criteria established in Internal Control- Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, because of the effect of the material weaknesses described in the following paragraph on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2018 based on criteria established in Internal Control- Integrated Framework (2013) issued by COSO.

A material weakness is a control deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company´s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management´s assessment.

1. The Company maintains insufficient controls in regards to transactions with related parties. The Company did not perform timely reconciliations of inter-company balances, and had insufficient controls over the preparation and maintenance of documents supporting the terms, authorization, or nature of such balances. The Company also failed to properly record interest in regards to such loans in the proper period, and was unable to distinguish between advances to related parties and trade payables/receivables arising in the ordinary course of business.

2. The Company maintained insufficient controls in regards to the information technology (IT) environment.

a. There is no documented management risk assessment framework on the effects of IT which would allow the group to determine the key controls for critical processes.

b. The Company had updated IT policies and procedures during 2018 which remained unapproved.

c. There is no process to verify that the computer accounts of former employees have been properly closed and that new accounts have appropriate rights in detail of their access.

d. The Company lacks a disaster recovery plan, there is no a documented plan regarding continuity of business operations (Business Continuity Plan), and documented back-up plans are not sufficient.

e. There is a need for an IT infrastructure that guarantees safer conditions to avoid loss of information on the company's servers.

These material weakness or combination of deficiencies was considered in determining the nature, timing, and extent of the audit test applied in our audit of the 2018 financial statements, and this report does not affect our report dated July 30, 2019, on those financial statements.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the balance sheets as of December 31, 2018 and 2017 and the related statements of income, comprehensive income, stockholders ‘equity, and cash flows for each of the years in the three-year period ended December 31, 2018, and our report dated July 30, 2019, expressed an unqualified opinion on those financial statements.

112 

Basis for Opinion

The Company´s management is responsible 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 “Managements Annual Report on Internal Control Over Financial Reporting”. Our responsibility is to express an opinion of the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 omission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining and 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 audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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.

D. Changes in Internal Control Over Financial Reporting

Fiscal Year Ended December 31, 2014

As a result of our evaluation on the effectiveness of our internal controls for the year ended December 31, 2014 and the material weakness and deficiencies identified during that period, we will need to increase the resources allocated to implement the remedial measures due to prevalence of deficiencies from previous years. If we implement the following remedial measures, we believe such are reasonably likely to materially improve our internal controls over financial reporting:

● We will allocate the required resources to review and reform our entity level controls to ensure compliance with the COSO framework, complete the transition to the COSO 2013 framework and address all the issues that were found on our 2014 assessment of our internal control.

114 

● We will increase the internal audit staff to execute testing of control activities that was not otherwise executed on the 2014 management Assessment.

● We will conduct an analysis of functions and workloads in the finance departments of all of our Mexican Subsidiaries in order to improve internal controls over financial reporting and to avoid the errors found with respect to our financial statement closing process, and preparation of financial statements under IFRS.

● In our subsidiary Corporación Aceros D.M., S.A. de C.V. we will assign more resources to implement the remedial measures that have not been implemented in the last three years and to complete the transition into the 2013 COSO framework.

Fiscal Year Ended December 31, 2015

As a result of the evaluation on the effectiveness of our internal controls for the year ended December 31, 2015 by our external auditors and the material weakness and deficiencies identified during that period, we will need to increase the resources allocated to implement the remedial measures due to their prevalence from previous years. If we implement the following remedial measures, we believe such are reasonably likely to materially improve our internal controls over financial reporting:

● We will allocate the required resources to reform our entity level controls to ensure compliance with the COSO framework, complete the transition to the COSO 2013 framework and address all the issues that were found on our 2015 assessment of our internal control.

● We will conduct an analysis of functions and workloads in the finance departments of all of our subsidiaries in order to improve internal controls over financial reporting to avoid errors found with respect to our financial statement closing process, and preparation of financial statements under IFRS.

● In our subsidiary Corporación Aceros D.M., S.A. de C.V. we will assign more resources to implement the remedial measures that have not been implemented in the last four years and to complete the transition into the 2013 COSO framework.

● We will designate a new head of the Internal Audit Department and we will strengthen the internal audit function by hiring (one or two) employees to conduct the testing activities of the internal controls over financial reporting.

● We will invest Ps.1.5 million in hiring an outside firm to assist our management and our Internal Audit Department in implementing remedial measures for the material weaknesses found in previous years.

Fiscal Year Ended December 31, 2016

As a result of the evaluation on the effectiveness of our internal controls for the year ended December 31, 2016 by our external auditors and the material weaknesses and deficiencies identified during that period, the company worked to address material weaknesses and significant deficiencies, focusing particularly on those that were feasible to address within the last quarter of 2016. To this end, the company engaged Mazars, a group of external advisors, to assist in the production of a work plan to resolve or mitigate such material weaknesses and significant deficiencies (although such material weaknesses and significant deficiencies were not resolved or mitigated as of December 31, 2016), including through the following:

●           Promoting the validation of the code of ethics by the internal audit committee and senior management, so that it will be distributed to new and existing employees, in the first instance, to employees in each business unit.

●           Aligning the internal control evaluations with the COSO 2013 framework. The company conducted training for the internal auditors in the last quarter of 2016 that will promote the alignment of the evaluation of the internal controls for 2016.

●          Adhere to the methodology suggested by the external consultants (Mazars) to carry out a SOX audit, starting with the selection of significant accounts, cycles and business units (scoping) in order to, through a risk and control matrix, evaluate the risks and controls in terms of design and control efficiency.

●           The company believes that it now has a team of internal auditors that will allow it to carry out audit activities in a timely manner, as each business unit now counts with an auditor (USA, Mexicali, Tlaxcala, Guadalajara, San Luis Potosí and Brazil).

115 

●           The procedures that need to be updated have been identified through the courses carried out for supply cycles, fixed assets, accounting closure, consolidation and treasury. However, it has a remediation plan to include in a technological tool all the procedures of the business cycles, thus allowing existing versions.

●           The policies that need to be updated have been identified and the company has commenced with the updating and improvement of the policies included in the accounting manual. The company intends to complete all policies in a period of no more than two years.

●           The company has put out a tender for suppliers of services for the whistleblower line. Although the supplier has not yet been selected, is in the process of obtaining quotes from two selected suppliers.

●           In connection with the integration of accounting information, the company is developing a procedure with mitigating controls to reduce the risk of not having a consolidated ERP, as the company is not contemplating to acquire an ERP at least for the year 2017.

●           A work plan for 2017 was also drawn up between external advisors (Mazars) and the company to carry out the remediation or mitigation of the internal control deficiencies.

The implementation of these changes commenced during the last quarter of 2016 and the first quarter of 2017. The company believes it is implementing a robust work plan aligned with the SOX methodology and the COSO 2013 framework, which promotes the participation of top management and business process owners who will actively participate in the implementation of the identified controls.

Management’s Annual Report on Internal Control over Financial Reporting

As part of its commitment to comply with the Sarbanes-Oxley Act and the correct administration of risks and controls within the Company's operations, Grupo Simec has assembled a complete internal audit team.

In addition, Grupo Simec contracted Mazars, a consulting firm, to advise on the remediation of the material weaknesses included in its past annual reports on Form 20-F, to aid in the execution and implementation of controls and continue aligning the internal control system of the Company with the COSO 2013 framework.

We have performed actions to improve the internal controls at all levels of the organization, including at the top level, and performed remediation actions such as the establishment of the whistleblower hotline and the update and distribution of our code of ethics.

From the local plant director and local finance director of each plant to the corporate CEO and CFO, all have been trained in the different aspects of our control environment and the administration of the risks and controls of our key financial processes.

Status of Remediation Plans

Our internal audit team, with the validation of the Audit Committee, the CEO and the CFO, developed a program of remediation plans to resolve the material weaknesses detected in the internal control system for the entire company.

The process leaders of each plant, supported with the advice of the internal audit team and Mazars, implemented the remediation plans in order to resolve the material weaknesses reported in our annual reports on Form 20-F for the years ended on December 31, 2015, December 31, 2016, and December 31, 2017, as well as the findings identified in the assessment on internal controls over financial information as of December 31, 2018.

Remediation Actions related to Corporate Governance

· Remediation of the control environment with the first and second level executives of all the plants, including the standards, processes and structures in the Board of Directors and senior management, in order to align with the first five principles of COSO 2013.

· Training the audit team and Audit Committee on the COSO 2013 internal control framework and Sarbanes-Oxley Act. Developing a training program in each plant and distributing the Code Of Ethics and ensuring its correct understanding throughout the organization.

· The firm Resguarda was hired to implement a whistleblower hotline and disseminate it to all plants.

· The results of Internal audit findings were formalized and consolidated in an internal letter of certification signed by the General Director and the Corporate Finance Director of Grupo Simec. The objective of this letter is to have a formal follow-up of the remediation plans developed in order to attend to the deficiencies detected.

Remediation Actions related to Internal Control over Financial Reporting

The findings identified within the 2018 internal audit regarding internal controls over financial reporting (ICFR) in all the plants (Guadalajara, San Luis Potosí, Tlaxcala, Mexicali, Brazil and the United States) were addressed and mostly resolved.

Remediation Actions related to Information Technology General Controls (ITGC)

· The Company is working on remediation plans in each of the plants in connection with the documentation of IT policies and procedures under a COBIT framework approach.

· We are evaluating the need to increase our IT corporate infrastructure to provide a strategic IT vision for each plant.

Remediation Actions for Related Party Transactions

We are in the process of documenting the related party transaction policy setting forth the way in which such transactions should be documented and authorized.

Follow-up to Remediation Plans

As part of the responsibilities and commitments established by senior management in order to improve the policy controls and established procedures, compliance with remediation plans will be monitored as part of the activities of the internal audit department during 2019.

As of December 31, 2018, the Company believes it complied with the remediation plans identified in the annual report on Form 20-F for the year ended December 31, 2017, and has completed or is in the process of implementing mitigating controls to remedy in full the material weaknesses or significant deficiencies identified.

Item 16A. Audit Committee Financial Expert

Our board of directors has determined that it has at least one “audit committee financial expert,” as defined in Item 16.A of Form 20-F, serving on the Audit Committee.

Item 16F. Change in Registrant’s Certifying Accountant

Not applicable.

Item 16G. Corporate Governance

Our following corporate governance practices differ from the New York Stock Exchange standards in the following ways:

Board of Directors Composition, Nomination and Board Meetings. Pursuant to the Mexican Securities Market Law, our board of directors must be composed of a maximum of 21 members, of which at least 25% must be independent. The board of directors is elected by the shareholders at the annual meeting, for a one year term with the option to be reelected, as determined by the shareholders. One alternate director may be appointed for each director, provided that independent alternates are appointed for the independent directors. In accordance with Mexican law, our shareholders determine directors’ independence during the annual shareholders meeting, but this independence determination may be challenged by the CNBV. Our board of directors meets at least quarterly and resolutions are binding if adopted by a majority of the directors present at a meeting.

Nominating and Compensation Committees. In compliance with Mexican laws, we do not have a nominating or compensation committee. Members of our board of directors are appointed by a majority of shareholders present at our annual shareholders meeting. We do have a corporate practice committee, made up of three independent directors, that assists the board in determining executive compensation. Shareholders, at our annual shareholders meeting, or the board of directors, make the final determination about executive compensation. Shareholders’ approval must be acquired for the adoption and amendment of any equity compensation plans (we do not currently have any equity compensation plan).

Audit Committee and Auditors. Our Audit Committee is governed by: (i) our by-laws and (ii) Mexican law. Our Audit Committee is made up of at least three independent directors, appointed by the board of directors. Our shareholders appoint and/or remove the chairman of the Audit Committee at the annual shareholders meeting. In accordance with Mexican law, the Audit Committee must provide an opinion regarding any transaction with a related party, outside of the ordinary course of business. Such transactions must also be approved by the board of directors.

Under Mexican law, we must be audited by an independent public accountant that has received a “quality control review,” as defined by the general rules issued by the CNBV. These general rules require accounting firms rendering external audit services, to fulfill higher independence standards, as well as issuing and following quality control internal policies and manuals in accordance with the rules issued by the Mexican Institute of Public Accountants (Instituto Mexicano de Contadores Públicos, A.C.).

122 

Quorum Requirements and Shareholders’ Approval. In compliance with Mexican law, shareholders representing 50% of our capital stock must be present to conduct business at the first call for ordinary shareholders meetings, dealing with general matters. If a quorum is not reached, there is no minimum quorum requirement for a second or subsequent call. Resolutions approved at ordinary shareholders’ meetings are valid when approved by a majority of the shares present. On the other hand, shareholders representing 75% of our capital stock must be present to conduct business at the first call for extraordinary shareholders meeting dealing with modifications to the our by-laws. If a quorum is not reached, shareholders representing 50% of our capital stock must be present at the meeting in a second or subsequent call. Resolutions at extraordinary shareholders meetings are valid if approved by shares representing more than 50% of our capital stock. However, resolutions regarding the (i) quorum requirements, (ii) minority shareholders’ rights, (iii) merger, spin-off and conversion are valid if approved by at least 75% of our capital stock. Furthermore, resolutions regarding our registration with the National Securities Registry (Registro Nacional de Valores) are valid if approved by at least 95% of our capital stock. Class II Series “L” Shares, representative of our capital stock with limited economic and corporate rights, are not taken into account when determining the quorum at the general shareholders’ meeting. Currently there are no Class II Series “L” Shares outstanding.

Code of Conduct and Ethics. In compliance with Mexican law, we have a code conduct and ethics for our directors or executive officers. Also, our directors’ and executive officers’ conduct is subject to the applicable provisions of the Mexican Securities Market Law and the regulations issued by the CNBV.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the board of directors of

Grupo Simec, S.A.B. de C.V.

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Grupo Simec, S.A.B. de C.V. and its subsidiaries (the "Company") as of December 31, 2018, 2017 and 2016, and the related consolidated statements of comprehensive income (loss), changes in stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2018, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2018, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company´s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control- Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated July 30, 2019, expressed an adverse opinion.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits 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. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 24 of the financial statements, the 2017 and 2016 financial statements have been restated to correct a misstatement.

3. Application of new and amended standards and interpretations and standards not in force yet

The consolidated financial statements of Grupo Simec, S.A.B. de C.V. and its Subsidiaries for the periods presented have been prepared in accordance with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB). IFRS also includes all current International Accounting Standards (IAS), in force, as well as all related interpretations issued by the IFRS Interpretations Committee (IFRIC), including those issued previously by the Standing Interpretations Committee. The company applied the effective IFRS as of December 31, 2018.

F-7 

a.        International Financial Reporting Standards, not in force yet.

Below are the rules and amendments that could have an effect on Simec's financial information, which were issued by the IASB, but are not in effect at the date of these financial statements

Rules applicable starting from 2018:

a)   IFRS 15- Revenue from contracts with customers.

The IASB has published a new standard, IFRS 15- Income from contracts with customers (IFRS 15 or the new standard). The new standard describes a single comprehensive model for accounting of revenue from customer contracts and replaces current revenue recognition guidelines included in IFRS standards and interpretations.

The basic principle of the new rule is that an entity must recognize the income that represents the transfer of goods or services promised to the client, valued by the amount that the entity expects to receive in exchange for such goods or services.

The entities must:

• Identify the contracts with clients which are within the scope of the new standard;

• Identify the performance obligations in the contract: i) sales of goods or services separately, ii) sales dependent or interrelated with other products or services; (iii) homogeneous and consistent sales;

• Determine the price of the transaction: i) variable consideration and restricted estimates, ii) time value of money and financing component, iii) non-monetary consideration, iv) consideration paid to the customer;

• Distribute the transaction price among each separable performance obligation; and

• Recognize income when each performance obligation is met: (i) over time, (ii) at a point in time.

The new IFRS 15 increases disclosures on income and is effective for periods beginning on or after January 1, 2018, allowing for early application. Entities may choose to retroactively apply the standard or use a modified approach in the year of application.

b) IFRS 9 (2014) - Financial Instruments.

The IASB published IFRS 9 (2009) and IFRS 9 (2010) which introduced new classification and valuation requirements, and in 2013 disclosed a new model for hedge accounting. IFRS 9 published in July 2014 represents the final version of the standard, supersedes previous versions of IFRS 9, and completes the IASB project to replace IAS 39, Financial Instruments.

IFRS 9 (2014) includes a logical model for classification and valuation, a single, forward-looking model of impairment, and an approach with substantive changes to hedge accounting.

Classification and valuation

The classification determines how financial assets and financial liabilities are recorded in the financial statements and, in particular, how they are valued continuously. IFRS 9 (2014) introduces a logical approach to the classification of financial assets, which is based on the flow characteristics and the business model in which the asset is held. This unique, principled approach replaces existing requirements.

Impairment

The new model results in the application in a single model of impairment to all financial instruments, thus eliminating a source of complexity associated with the previous requirements. As a part of IFRS 9 (2014), IASB has introduced a new impairment model based on expected losses, which will require a timelier recognition of expected losses. Specifically, the new standard requires entities to recognize expected losses since the initial recognition of financial instruments as well as over the life of the

F-8 

instrument on a timelier basis. Further disclosures will be required on how the losses and the movement of the loss estimate were determined and of the activity of the estimate for losses.

Hedge Accounting

IFRS 9 (2014) introduces an approach with substantive changes for hedge accounting, with improvements to disclosures about risk management activities. The new model represents a major overhaul of hedge accounting, which aligns accounting manage with risk management activities, allowing entities to better reflect these activities in their financial statements. In addition, as a result of these changes, users of financial statements will be better informed about risk management and the effect of hedge accounting on financial reporting.

Own credit risk

IFRS 9 (2014) also eliminates the volatility in results that was caused by changes in the credit risk of liabilities that are valued at fair value. This accounting change means that gains proceeding from the impairment of the risk of our credit on these liabilities are no longer recognized directly in net earnings or loss but in other comprehensive income (OCI).

IFRS 9 (2014) will come into force for fiscal years beginning on or after January 1, 2018. Early application is allowed. In addition, changes in credit risk can be applied in advance and in isolation, without the other changes in the recognition of financial instruments.

Amendments applicable from 2018

a) Amendment to IAS 40 - Investment Property.

The amendment clarifies that the transfer of an investment in property will occur when and only when there is a change in its use. A change of use occurs when the property meets, or fails to meet, the definition of investment property and there is evidence of change of use. In isolation, a change in management's intentions to use a property does not provide evidence of a change in use.

b) Amendment to IAS 28 - Investments in Associates and Joint Ventures.

This amendment clarifies that a venture capital organization, collective investment fund, investment trust and other similar entities may opt, at initial recognition, to measure investments in associates and joint ventures at fair value through changes in profit and loss separately for each associate and joint business.

In addition, this amendment allows, in applying the equity method, that an entity other than an investment entity retains the measurement of the fair value applied by its associates and joint ventures. It also clarifies that this option is available at the initial recognition for each associate or joint venture that is an investment entity.

c) Amendments to IFRS 2 - Classification and measurement of share-based payment transactions.

The amendments clarify the following:

• When estimating the fair value of a share-based payment settled in cash, accounting for the effects of the acquisition conditions and the liability incurred should follow the same approach as for stock-based share-based payment.

• Where tax laws or regulations require an entity to withhold an amount because of an employee's tax liability associated with a share-based payment, the share-based payment arrangements may allow or require to retain a specified number of equity instruments Equivalent to the monetary value of the employee's tax liability, that is, the share-based payment arrangement has a "net settlement characteristic", if the agreement does not include the net settlement characteristic, that agreement should be classified as a whole Transaction with share-based payments settled with equity instruments.

• A share-based payment that is modified to change the settlement transaction in cash to the settlement of capital, should take into account the following:

F-9 

i. The original liability is written off;

ii. The share-based payment with share liquidation is recognized on the date of modification of the fair value of the equity instrument granted to the extent that the services had been rendered until the date of modification; and

iii. Any difference between the carrying amount of the liability at the date of change and the amount recognized in the net equity must be recognized immediately in profit or loss.

Amendments are effective for annual reporting periods beginning on or after January 1, 2018 with anticipated permitted application.

Interpretation applicable from 2018:

a) IFRIC 22- Transactions in foreign currency and considerations paid in advance.

IFRIC 22 Interpretation, issued by the International Accounting Standards Board, developed by the IFRS Interpretations Committee, addresses how to determine the date of the transaction for the purpose of establishing the exchange rate to be used in the initial recognition of the asset, expense or related income on the write-off of a non-monetary asset or non-monetary liability arising from the payment or collection of the anticipated consideration in foreign currency.

It is established that the date of the transaction for the purpose of determining the exchange rate to be used in the initial recognition is the date on which an entity initially recognizes the non-monetary asset or non-monetary liability arising from the payment or collection of the anticipated consideration. If there are multiple payments or prepayments, the entity will determine a date of the transaction for each payment or collection of the anticipated consideration.

Standard applicable from 2019:

In January 2016, the IASB published a new accounting standard, IFRS 16 - Leases, which repeals IAS 17 - Leases and the related interpretation guides.

The main changes in relation to the previous rule are:

i. IFRS 16 provides a comprehensive model for the identification of lease contracts and their treatment in the financial statements of tenants and landlords.

ii. The new standard applies a control model for the identification of leases, distinguishing between leases and service contracts based on whether there is an asset identified and controlled by the customer.

iii. The distinction between operating and finance leases is eliminated; therefore, the assets and liabilities of all leases are recognized, with some exceptions, for leases of short-term low-value assets.

iv. The standard does not include significant changes in the requirements for the lessor's accounting.

The standard is effective for annual periods beginning on or after January 1, 2019, with early application permitted for entities that have also adopted IFRS 15- Income from Contracts with Customers.

As of today, Simec continues to evaluate the effect that this new standard could have on its financial statements.

Amendments applicable from 2019:

a) Amendment  to IFRS 28 - Long-term investments in associates and joint ventures.

This amendment clarifies that entities will account for long-term investments in an associate or joint venture (to which the equity method is not applied), using IFRS 9 before accounting for losses or losses due to impairment, applying IAS 28.

F-10 

b) Amendment  to IFRS 3 - Business combination.

This amendment clarifies that when an entity obtains control of a business that is a joint operation, it will measure again the participation maintained in that business.

c) Amendment to IFRS 11 - Joint agreements.

This amendment clarifies that when an entity obtains joint control of a business that is a joint operation, it will measure again the participation maintained in that business

d) Amendment  to IAS 12 - Income tax.

This amendment clarifies that an entity will account for all the consequences of dividends on income tax in the same way, regardless of how the tax arises.

e) Amendment  to IAS 23 - Costs for loans.

This amendment clarifies that when an asset that meets the requirements to be suitable for its intended use or sale, an entity will treat as part of the general loans, the outstanding loans taken to obtain that eligible asset.

f) Amendment  to IAS 19 - Benefits to employees.

This amendment requires that when a change occurs in the plan (modification, reduction or liquidation), the company remeasures its liability or assets for net defined benefits. Previously, it was not specified how to determine the expenses for the period after the change in the plan. The amendments require an entity to use the updated assumptions of the new measurement to determine the current cost of the service and the net interest for the remainder of the reporting period after the change to the plan.

The amendments are effective for annual reporting periods beginning on January 1, 2019, with early application allowed.

Interpretation applicable from 2019:

IFRIC 23 - Uncertainty regarding the treatment of income tax.

The IFRIC 23 interpretation, issued by the International Accounting Standards Board, developed by the IFRS Interpretations Committee, adds to the requirements of IAS 12 - Income taxes, the specification of how to reflect the effects of the uncertainty in accounting for income tax, when it is unclear how to apply tax laws to a particular transaction or circumstance, or it is unclear whether a tax authority will accept the treatment of an entity.

This interpretation will apply for the annual reporting periods that begin as of January 1, 2019, with early application allowed.

Amendments applicable from 2020:

a) Conceptual Framework

In March 2018, the IASB issued a new revised version of the conceptual framework for financial information. The Conceptual framework for financial information contains updated definitions of assets and liabilities in the financial statements. In addition, new concepts and guidance have been added to the following topics:

i. Measurement, including the factors to be considered when selecting a measuring base.

ii. Presentation and disclosure, including when to classify income and expenses in other comprehensive income.

iii. The reporting entity.

iv. When the asset and liabilities are eliminated from the financial statements.

The conceptual framework also clarifies the roles of management, prudence, and uncertainty of measurement in financial reporting.

Several IFRSs have also been amended for references to the conceptual framework. The amendments to the IFRS for changes to the conceptual framework, update some of these references and quotations to refer to the conceptual framework for financial reporting issued in 2018 and makes

F-11 

other amendments to clarify what version of the Conceptual framework is mentioned in each document.

b) Amendment to IFRS 3 – Business combination.

This amendment clarifies the definition of a business, with the objective of helping entities determine whether a transaction should be accounted for as a business combination or as an acquisition of assets. The amendment consists of the following:

I. It clarifies that, in order to be considered a business, an acquired set of activities and assets must include at least a contribution and a substantive process, which together contribute significantly to the ability to create products.

II. Eliminates the evaluation of market participants to determine if they are able to replace any missing inputs or processes and continue to produce products.

III. Adds guidance and illustrative examples to help entities determine whether a substantive process has been acquired.

IV. Restricts the definitions of a business and products by focusing on the goods and services provided to customers and eliminating the reference to the ability to reduce costs.

V. Adds an optional concentration test that allows for a simplified assessment of whether an acquired set of activities and assets is not a business.

c) Amendments to IAS 1 - Presentation of financial statements and IAS 8 - Accounting policies, changes in estimates and accounting errors.

These amendments clarify the definition of "Material" and, consequently, modifications are made to a number of other standards by the definition of Material.

The amendments improve the understanding of the definition of material to: 

I. Align the drafting of the definition in the IFRS standards and the conceptual framework, to avoid the possibility of confusion arising from different definitions. 

II. Incorporate the support requirements in IAS 1, in the definition to give them greater importance and clarify their applicability; and 

III. Provide existing information on the definition of Material, along with the definition.

Simec is evaluating the impact that these changes could have on their financial statements.

4) Basis of preparation and presentation of the financial statements

The consolidated financial statements have been prepared in accordance with IFRS as discussed in Note 3, based on historical costs. Historical cost is generally based on the fair value of the consideration given in exchange for assets.

Consolidation basis – The consolidated financial statements include the financial statements of Grupo Simec, S.A.B. de C.V. and the entities controlled by the Company (its subsidiaries). Control is obtained when the company possesses the power to govern the financial and operative policies of an entity in order to obtain benefits from its activities. The results of subsidiaries acquired or sold during the year are included in the consolidated financial statements from the date of acquisition or up to the date of sale, as the case may be. Total comprehensive income (loss) of subsidiaries is attributed both to the Company and to the non-controlling interests even if the non-controlling interests have a deficit balance reflecting allocated losses.

Within the consolidation process, adjustments are made to the financial statements of the subsidiaries to adapt their accounting policies so that they are aligned with those used by the Company. All significant intercompany transactions and balances between companies are eliminated during consolidation.

Changes in investments in subsidiaries of the Company that do not result in a loss of control are recorded as equity transactions. The book value of the company's non-controlling investments and shares is adjusted to reflect changes in the corresponding investments in subsidiaries. Any difference

F-12 

between the amount by which non-controlling shares are adjusted and the fair value of the consideration paid or received is recognized directly in the estate and is attributed to the owners of the company.

When the company loses control of a subsidiary, the profit or loss in the provision is calculated as the difference between (i) the sum of the fair value of the consideration received and the fair value of any retained participation and (ii) the value in Previous books on assets (including commercial credit) and liabilities of the subsidiary and any non-controlling participation. The amounts previously recognized in other comprehensive income items related to the subsidiary are recorded (that is, reclassified to profit or loss or transferred directly to retained earnings) in the same manner established for the case of the disposal of significant assets or liabilities. The fair value of any investment retained by the former subsidiary on the date of loss of control is regarded as the fair value for initial recognition in its subsequent accounting treatment, according to IAS 39, financial instruments: Recognition and valuation, or, where appropriate, the cost in the initial recognition of an investment in an associate or entity under joint control.

Summary of the main accounting policies –The preparation of the attached consolidated financial statements requires the company's management make certain estimates and use certain assumptions to value some of the items in the financial statements and to make the disclosures required in the same. However, actual results may differ from these estimates. The Company’s management, using its professional judgment, believes that the estimates made and assumptions used were adequate under the circumstances. The significant accounting policies of the Company are those mentioned below:

a. Conversion of foreign subsidiaries financial statements – The functional and reporting currency of the Company is the Mexican peso ($). The financial statements of foreign subsidiaries were translated to Mexican pesos in accordance with International Accounting Standard (IAS) 21, The Effects of Changes in Foreign Exchange Rates. Under this standard, the first step to convert financial information from operations abroad is the determination of the functional currency. The functional currency is the currency of the primary economic environment of the foreign operation or, if different, the currency that mainly impacts its cash flows.

The U.S. dollar (US Dollar or USD$) was considered as the functional currency of all the U.S. subsidiaries and Brazilian Real for subsidiaries established in Brazil; therefore, the financial statements of these subsidiaries abroad were converted to Mexican pesos applying:

- The exchange rates at the balance sheet date, to all assets and liabilities.

- The historical exchange rate at stockholders’ equity accounts and revenues, costs and expenses.

The conversion differences are carried directly to the consolidated statements of comprehensive income as other comprehensive income under the caption translation effects of foreign subsidiaries.

Relevant exchange rates used in the preparation of the consolidated financial statements of foreign subsidiaries were as follows (Mexican pesos per one U.S. dollar):

Current exchange rate as of December 31, 2018	19.66
Current exchange rate as of December 31, 2017	19.74
Average exchange rate for the year ended December 31, 2018 (*)	19.23
Average exchange rate for the year ended December 31, 2017 (*)	18.94
Current exchange rate as of April, 9 of 2019	18.97

(*) Average exchange rate used to translate revenues, costs and expenses of the companies mentioned above.

b. Business combinations – Acquisitions of subsidiaries and businesses units are accounted for

F-14 

using the acquisition method. The consideration for each acquisition is valued at its fair value on the date of exchange of the transferred assets, liabilities incurred or assumed and capital instruments issued by the Company in exchange for control of the acquired. The costs related to the acquisition are recognized in the results when incurred.

At the date of acquisition, the identifiable assets acquired and the liabilities assumed are recognized at their fair value, except:

- Deferred tax assets or liabilities and liabilities or assets related to employee benefit arrangements, which are recognized and measured in accordance with IAS 12, Income Taxes, and IAS 19, Employee Benefits, respectively.

- Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5, Non-current Assets Held for Sale and Discontinued Operations, are measured in accordance with that Standard.

Any excess of the cost of acquisition for the Group's interest in the net fair value of the identifiable assets, liabilities and contingent liabilities of the associated company recognized at the date of acquisition is recognized as goodwill. Goodwill is included in the carrying amount of the investment and is assessed for impairment annually. Any excess of the Group's interest in the net fair value of the assets, liabilities and contingent liabilities over the cost of acquisition, after the reassessment, is immediately recognized in profit and loss.

When the consideration transferred by the Company in a business combination includes assets or liabilities resulting from a contingent consideration arrangement, the contingent consideration is measured at its acquisition-date fair value and later adjustments to the consideration are recognized against goodwill, providing that it has arisen from reliable information on the fair value at the acquisition date and occur during the ‘measurement period’ (which cannot exceed one year from the acquisition date). All other subsequent adjustments are recognized in profit or loss.

The subsequent accounting for changes in the fair value of the contingent estimates that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates. Contingencies classified as assets or liabilities are remeasured at subsequent reporting dates in accordance with IAS 37, Provisions, Contingent Liabilities and Contingent Assets, as appropriate, with the corresponding gain or loss being recognized in profit or loss.

When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree are remeasured to fair value at the acquisition date (i.e. the date when the Company obtains control) and the resulting gain or loss, if any, is recognized in profit or loss. Amounts arising from interests in the acquiree prior to the acquisition date that have been previously recognized in other comprehensive income (loss) are reclassified to profit or loss where such treatment would be appropriate if that interest were disposed of.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date.

c. Cash and cash equivalents and temporary investments – Cash consists of deposits in bank accounts that do not generate interest. Cash equivalents consists in temporary investments referred to as short-term fixed income investments whose original maturity is less than three months. These investments are reported at cost plus accumulated interest. The value so determined approximates their fair value.

Temporary investments in equity instruments are measured at the fair value prevailing at the date of the financial statements. Subsequent changes in the fair value are recognized in profit or loss.

F-15 

d. Allowances for doubtful accounts – The Company follows the practice of recording an estimation of an allowance for doubtful accounts, which is determined by considering the balances of clients with more than a year old, those in litigation and or specific recovery problems. Actual results may differ materially from these estimates in the future.

e. Inventories and cost of sales – Inventories are stated at the lower of cost or net realizable value. The cost allocation formula used is the average cost. The cost includes acquisition costs of materials, labor and overhead costs related to manufacturing and distribution, based on normal activity levels. The net realizable value represents the estimated selling price for inventories less all estimated costs of completion and other necessary to make the sale, which is recorded in the statement of financial position and against account is the cost of sales.

The Company classifies raw material inventory in the Consolidated Statements of Financial Position based on its expected consumption period, presenting as long-term inventories those which in accordance with historical data and production trends will not be consumed in the short-term (one year).

The Company classified as long-term inventory certain parts and rollers that, according to historical data and trends, showing that such inventories will not be consumed in the short-term. The Company utilizes coke, a form of coal, as a raw material input to fuel its blast furnace which has been inactive in Lorain, Ohio USA plant (see Note 9). The Company has 136,541 metric tons (MT) of coke inventory valued at 953 million Mexican pesos (average of USD$ 355/MT) on hand at December 31, 2018 and 136,541 MT of coke inventory valued at 1,037 million Mexican pesos (average of USD$ 385.00/MT) on hand at December 31, 2017 that is classified as long-term in the accompanying Consolidated Statements of Financial Position.

The Company follows the practice of providing a reserve for slow-moving inventory, considering the total of products and raw materials (including coke) with a turnover above one year, which is recorded in the statement of financial position and against account is the cost of sales.

The cost of sales of the Company includes inventory costs, outbound freight charges, purchasing and receiving costs, inspection costs, and warehousing costs in cost of goods sold. Vendor payment incentives are recorded as a reduction to cost of goods sold.

f. Property, plant and equipment – Property, plant and equipment are recorded at acquisition cost less any recognized impairment loss. Cost includes all expenses related with acquisition and installation and, for qualifying assets, borrowing costs (interest) capitalized in accordance with the Company’s accounting policy. Depreciation is recognized so as to write off the cost of assets (other than land and properties under construction) less their residual values over their useful lives, using the straight-line method, and commences when the assets are ready for their intended use. The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period, with the effect of any change in estimates accounted for on a prospective basis.

An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in profit or loss.

The initial estimated useful lives of the Company’s main assets are as follows:

	Years
Buildings	10 to 65
Machinery and equipment	5 to 40
Transportation equipment	4
Furniture, mixtures and computer equipment	3 to 10

Repair and maintenance costs that significantly increase productive capacity or extend the useful lives of existing plant and equipment are capitalized. Supplies, comprising of spare parts and consumables for internal use are classified under property, plant and equipment and expensed as incurred in the manufacturing process. All other repair and maintenance costs are

F-16 

expensed as incurred. Capital expenditures for projects that cannot be put into use immediately are included in constructions and machinery in-progress. When constructions and machinery in-progress are completed, they are transferred to depreciable assets.

g. Leases – Leases are classified as financial leases when the terms of the lease contract substantially transfer to tenants all the risks and benefits inherent in the property. All other leases are classified as operating leases.

Operating lease payments are recognized as an expense on a straight-line basis over the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred.

In the event that lease incentives are received to enter into operating leases, such incentives are recognized as a liability. The aggregate benefit of incentives is recognized as a reduction of rental expense on a straight-line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.

h. Costs for loans – Costs for loans directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are ready for their intended use or sale.

Investment income earned on the temporary investment of specific loans pending their expenditure on qualifying assets is deducted from the costs for loans eligible for capitalization.

All other costs for loans are recognized in profit or loss in the period in which they are incurred.

i. Intangible assets – Intangible assets with definite useful lives that are acquired separately are carried at cost, less accumulated amortization and accumulated impairment losses. Amortization is recognized on a straight-line basis over their estimated useful lives. The estimated useful life and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for, on a prospective basis. Intangible assets with indefinite useful lives that are acquired separately are carried at cost less accumulated impairment losses.

Expenditure on research activities is recognized as an expense in the period in which it is incurred.

An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognized if, and only if, all of the following have been demonstrated:

- The technical feasibility of completing the intangible asset so that it will be available for use or sale;

- The intention to complete the intangible asset and use or sell it;

- The ability to use or sell the intangible asset;

- How the intangible asset will generate probable future economic benefits;

- The availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and

- The ability to measure reliably the expenditure attributable to the intangible asset during its development.

The amount initially recognized for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally-generated intangible asset can be recognized, development expenditure is recognized in profit or loss in the period in which it is incurred. Subsequent to

F-17 

initial recognition, internally-generated intangible assets are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss.

j. Goodwill – Goodwill arising on a combination of business is carried as an asset at cost as established at the date of acquisition of the control of the business less accumulated impairment losses, if any. For the purposes of impairment testing, goodwill is allocated to each of the Company’s cash-generating units that would be expected to benefit from the synergies of the combination. A cash-generating unit to which goodwill has been allocated is tested for impairment annually, or more frequently when there is indication that the unit may be impaired. If the recoverable amount of the cash-generating unit is less than it´s carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro rata based on the carrying amount of each asset in the unit. An impairment loss recognized for goodwill is not reversed in subsequent periods. On disposal of the relevant cash-generating unit, the attributable amount of goodwill is included in the determination of the profit or loss on disposal.

k. Impairment of tangible and intangible assets other than goodwill – At the end of each reporting period, the Company reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any of such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified. Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually, and whenever there is an indication that the asset may be impaired. Recoverable amount is the higher of fair value less costs to sell and value in use. 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 for which the estimates of future cash flows have not been adjusted. If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than it´s carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease. Where an impairment loss subsequently reverses, the carrying amount of the asset (or a cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. For purposes of allocation of goodwill when there is business combination will be distributed among each of the cash generating units of the acquiring entity, expected synergy benefits. A reversal of an impairment loss is recognized immediately in profit or loss and allocated to the assets of that unit, the carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss of value shall not exceed the carrying amount that would have been obtained if had not recognized an impairment loss in value for the asset in prior periods. Unless the related asset is recognized at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase.

l. Provisions – Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that the Company will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

F-18 

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the balance sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, it´s carrying amount is the present value of those cash flows.

m. Employee benefits – The costs of direct benefits and defined benefit and defined contribution retirement plans are recognized as an expense when employees have rendered service entitling them to the right to receive those benefits.

The retirement benefit liability is determined based on the present value of the defined benefit obligation at the date of the statement of financial position. Any compensation included in the determination of the liability premiums corresponds to seniority premiums for retirement. Actuarial gains and losses are recognized on profit or loss for the year. The retirement benefit liability and the related net cost of the period are determined under the Projected unit credit method based on projected salaries and certain assumptions determined by independent actuaries.

Liabilities for employee benefits recognized in the consolidated statement of financial position represent the present value of the defined benefit obligation.

Republic operates various employee benefit plans. The contributions to these benefit plans are either contractually determined by the terms of a collective bargaining agreement with the United Steelworkers or they are under the terms of a defined contribution plan. Accordingly, the company pays fixed contributions to separate entities and they are expensed in the period in which the employees rendered the services entitling them to the benefits.

n. Earnings per share – Income per share is calculated by dividing net income related to the controlling interests, by the weighted average shares outstanding during each year presented.

o. Income taxes – Income taxes represents the sum of the tax currently payable and deferred tax.

- Current tax – The Company incurs Income Tax (ISR) (See note 15) which is recorded in the result in the year in which it is determined. Determined ISR is based on fiscal earnings. Fiscal earning differs from the gain reported in the Consolidated Comprehensive Income Statement, due to taxable income or deductible expenses in other years and items which are never taxable or deductible. The tax liability for the Company is computed using statutory rates promulgated or substantially approved at the end of the period on report.

- Deferred tax –Deferred tax is recognized on differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax basis using the liability method. Deferred tax liabilities are generally recognized for all taxable temporary differences, and deferred tax assets are generally recognized for all deductible temporary differences to the extent that it is probable that taxable profits will be available against which those deductible temporary differences can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable earnings will be available to allow all or part of the asset to be recovered.

Deferred tax assets and liabilities are computed using the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the balance sheet date. The effects of changes in the statutory rates are accounted for in the period that includes the enactment date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

F-19 

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its current tax assets and liabilities on a net basis.

The Company follows the practice of recognizing the benefit from the amortization of acquired or generated tax losses in current earnings that are amortized.

- Current and deferred tax for the period – Current and deferred tax are recognized as an expense or income in periodic profit or loss, except when they relate to items that are recognized in other comprehensive income (loss) or directly in equity, in which case, the current and deferred tax are also recognized in other comprehensive income (loss) or directly in equity, respectively.

- Interests on recoverable tax balances – Interest on recoverable tax balances are presented in the consolidated statements of comprehensive income as interest income.

p. Foreign currencies – In preparing the financial statements of each individual group entity, transactions in currencies other than the entity’s functional currency (foreign currencies) are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are retranslated at the rates prevailing at that date. In the case of non-monetary items, which arise from the payment or collection of anticipated considerations, are recognized at the exchange rate in force of the date of the transaction.

Exchange differences are recognized in profit or loss in the period in which they arise except for:

- Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings;

- Exchange differences on transactions entered into in order to hedge certain foreign currency risks; and

- Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to profit or loss on sell all or part of the net investment.

q. Financial instruments – Financial assets and financial liabilities are recognized when a group entity becomes a part to the contractual provisions of the instrument.

Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.

r. Financial assets – Financial assets are classified into the following specified categories: “financial assets at fair value through profit or loss”, “held-to-maturity investments”, “available-for-sale financial assets” and “loans and receivables”. The classification depends on the nature and purpose of the financial assets and is determined at the time of initial recognition. All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the time frame established by regulation or convention in the marketplace.

F-20 

The effective interest method is a method of calculating the amortized cost of a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, (where appropriate), a shorter period, to the net carrying amount on initial recognition.

The Company does not have financial assets classified as “available-for-sale financial assets”.

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and accounts receivable are measured at amortized cost using the effective interest method, less any impairment.

Financial assets are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected.

Objective evidence of impairment could include:

- Significant financial difficulty of the issuer or counterparty;

- Breach of contract, such as a default or delinquency in interest or principal payments;

- It becoming probable that the borrower will enter bankruptcy or financial re-organization; or

- The disappearance of an active market for that financial asset because of financial difficulties.

For certain categories of financial assets, such as trade receivables, assets that are assessed not to be impaired individually are, in addition, assessed for impairment on a collective basis. Objective evidence of impairment for a portfolio of receivables could include the Company’s past experience of collecting payments, as well as observable changes in national or local economic conditions that correlate with default on receivables.

For financial assets carried at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate.

The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in profit or loss.

Except for equity instruments available for sale, if, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through profit or loss to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed what the amortized cost would have been had the impairment not been recognized.

The Company recognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. If the Company neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Company recognizes its retained interest in the asset and an associated liability for amounts it may have to pay. If the Company retains substantially all the risks and rewards of ownership of a transferred financial asset, the Company continues to recognize the financial asset and also recognizes a collateralized borrowing for the proceeds received.

F-21 

On recognition totally a financial asset, the difference between the asset’s carrying amount and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income and accumulated in equity is recognized in profit or loss.

s. Financial liabilities – Debt and equity instruments issued by a group entity are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument. Financial liabilities are classified as either financial liabilities “at fair value through profit or loss” or “other financial liabilities”.

Financial liability at fair value with changes through profit or loss is a financial liability classified as held for trading or it is designated as at fair value with changes through profit or loss.

A financial liability is classified as held for trading if:

- It has been acquired principally for the purpose of repurchasing it in the near term;

- On initial recognition, it is part of a portfolio of identified financial instruments that the Company manages together and has a recent actual pattern of short-term profit-taking; or

- It is a derivative that has not been designated as a hedging instrument and fulfils the condition to be effective.

- A financial liability other than a financial liability held for trading may be designated as at fair value through profit or loss upon initial recognition if:

o Such  designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise;

o The  financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Company’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or

o It  forms part of a contract containing one or more embedded derivatives, and IAS 39, Financial Instruments: Recognition and Measurement, permits the entire combined contract (asset or liability) to be designated as at fair value through profit or loss.

- Financial liabilities at fair value through profit or loss are recorded at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in profit or loss incorporates any interest paid on the financial liability and is included in the ‘other gains and losses' line item in the consolidated statement of comprehensive income.

- Other financial liabilities including borrowings are subsequently measured at amortized cost using the effective interest method. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or (where appropriate a shorter period), to the net carrying amount on initial recognition.

- The Company derecognizes financial liabilities when, and only when, the Company’s obligations are discharged, cancelled or they expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in profit or loss.

t. Derivative financial instruments – The Company sometimes uses derivative financial instruments for hedging risks associated with natural gas prices; this commodity is used for the production of goods, for which it conducted studies on historical consumption, future

F-22 

requirement and commitments acquired, thus diminishing its exposure to risks other than its normal operating risks.

These derivatives are initially recognized at fair value at the date the derivative contracts are entered into and subsequently are remeasured to the fair value at the end of reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

To mitigate the risks associated with changes in natural gas prices occurring naturally as a result of the supply and demand on international markets, the Company uses natural gas cash-flow exchange contracts or natural gas swaps to offset fluctuations in the price of natural gas, whereby the Company receives a floating price and pays a fixed price. Fluctuations in natural gas prices from volumes consumed are recognized as part of the Company’s operating cost.

At the inception of the hedge relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument is highly effective in offsetting exposure to changes in fair values or cash flows of the hedged item attributable to the hedged risk.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income and accumulated under the heading of fair value of derivative financial instruments, net of the corresponding income taxes. The gain or loss relating to the ineffective portion of hedge instrument is recognized immediately in profit or loss, and is included in the cost of sales line item.

The Company periodically evaluates the changes in cash flows of the derivative instrument to analyze if the swaps are highly effective for mitigating the exposure to natural gas price fluctuations. A hedge instrument is considered to be highly effective when changes in its fair value or cash flows of the primary position are compensated on a regular or cumulatively basis, by changes in fair value or cash flows of the hedging instrument in a range between 80% and 125%.

Amounts previously recognized in other comprehensive income are reclassified to profit or loss in the periods when the hedged item is recognized in profit or loss, in the same line of the consolidated statement of comprehensive income as the recognized hedged item. However, when the hedged forecasted transaction results in the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in equity are transferred from equity and included in the initial measurement of the cost of the non-financial asset or non-financial liability.

Hedge accounting is discontinued when the Company revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exerted, or when it no longer qualifies for hedge accounting. Any gain or loss accumulated from the hedge instrument that had been recognized in other comprehensive income and accumulated in equity at that time remains in equity until the forecast transaction is ultimately recognized in profit or loss. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

u. Revenue from contracts with customers – The income derived from contracts with customers is recognized at the moment in which the control of the goods or services is transferred to the client for an amount that reflects the consideration to which the company expect to have rights, in exchange for those goods and services.

Sale of goods:

Revenues from the sale of the products manufactured by the company ("products") are recognized at the time the asset control is transferred to the customer. The normal credit term on the sale of products is 30 to 90 days after delivery.

F-23 

The Company considers that there are no other obligations to be fulfilled in the contracts, which are obligations to be fulfilled separately and in which a portion of the transaction price should be allocated. When determining the transaction price for the sale of products, the Company would consider the possible effects of the variable consideration, the existence of important financing components, the consideration other than cash and the consideration payable to the client.

Contract balances

Contractual assets

An asset of the contract is the right to obtain a consideration in exchange for the goods or services transferred to the client. If the Company fulfills an obligation when transferring goods or services to a customer before the customer pays the consideration or before the collection is due, an asset derived from the contract is recognized for the conditional consideration that the Company is entitled to collect.

Accounts receivable

An account receivable represents the company's right to collect a consideration that is unconditional, that is, only the passage of time is required so that the payment of the consideration is payable.

Contract liabilities and customer advances

A liability of the contract is the obligation to transfer control over goods or services to a customer, in the future, that arises from a collection right. If a customer pays the consideration before the Company transfers the goods or services, a contract liability is recognized when the payment is due and an advance from the client when the payment is made. Contract liabilities (or a customer's advance) are recognized as income when the Company fulfills its obligations under the contract.

v. Financial information by operating segment - An operating segment is an identifiable component of the Company that performs business activities, from which it may earn revenues and incur expenses, including those income and expenses related to transactions with other components of the entity and upon which the company has separate financial information that is evaluated regularly by the Board of Directors, in making decisions to allocate resources and assess segment performance.

w. Environmental liabilities - The Company and other steel companies are subject to stringent environmental laws and regulations. It is the policy of the Company to endeavor to comply with applicable environmental laws and regulations. The Company established a liability for an amount which the Company believes is appropriate, based on information currently available, to cover costs of environmental remediation it deems probable and estimable. The liability represents an estimate of the environmental remediation costs associated with the required future steps of remediation, based upon management's evaluation of probable outcomes. These estimates are based on currently available facts, existing technology and presently enacted laws and regulations. The precise timing of remediation activities cannot be reliably determined at this time due to the absence of any deadlines for remediation under the applicable environmental laws and regulations pursuant to which such remediation costs will be expended. Accordingly, the Company has not discounted its environmental liabilities. Currently no claims for recovery are netted against the recorded liabilities.

x. Cost of sales and expenses by function - The Company classifies its costs and expenses by function in the Consolidated Statements of Comprehensive Income, according to the industry practices where the Company operates.

5) Critical accounting judgments and key sources of estimation

In the application of the Company’s accounting policies, which are described in Note 4, management is required to make judgments, estimates and assumptions regarding the carrying amounts of assets and liabilities. The estimates and associated assumptions are based on historical experience, the future and other factors that are considered to be relevant. Actual results may differ from these

F-24 

estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis and the resulting changes are recorded on the period in which the estimate has been modified, if such change affects only that period or in future periods.

a. Critical accounting judgments – The following are the critical judgments in the application of accounting policies, apart from those involving estimations, that the management have made in the process of applying the Company’s accounting policies and that have the most significant effect on the amounts recognized in the financial statements:

- Functional currency – The Company’s management has evaluated all the indicators that in its opinion are relevant and has concluded that the Company’s functional currency is the Mexican Peso. Likewise, the Company has concluded that the functional currency of the companies located abroad are those mentioned in Note 4-a.

b. Key information for estimates – The following is the key assumptions, and other key sources of estimation at the consolidated balance sheet date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the following financial year.

- Allowance for doubtful accounts – Management applies judgment at each balance sheet date creating an allowance for doubtful accounts, in order to show the possible financial loss caused by the inability of customers to make the corresponding payments. The Company calculates its allowance based on the accounts receivable aging and other considerations for specific accounts.

- Net realizable value of inventory – At each balance sheet date, professional judgment is used to determine any impairment in inventory. Inventory is considered as impaired when its carrying value is higher than its net realization value.

- Impairment of long-lived assets in use – Management applies professional judgment at each balance sheet date to determine whether the long-lived assets in use are impaired. Long-lived assets in use are impaired when the carrying value is greater than the recoverable amount and there is objective evidence of impairment. The recoverable amount is the present value of the discounted future cash flows that will generate during the remaining useful life, or liquidation value (fair value).

- Estimating useful lives and residual values of property, plant and equipment – As described in Note 4 f, the Company reviews the estimated useful life and residual values of property, plant and equipment at the end of each annual reporting period.

- Impairment of goodwill – Determining whether goodwill is impaired requires an estimation of the value in use of the cash-generating units to which goodwill has been allocated. The value in use calculation requires management to estimate the future cash flows expected to arise from the cash-generating unit and a suitable discount rate in order to calculate present value.

- Employee Benefits - The valuation of employee benefits is carried out by independent actuaries based on actuarial studies. Among others, the following assumptions, which can have an effect are used:(i) discount rates, (ii) the expected growth rates of wages and (iii) turnover rates and mortality recognized tables.

A change in the economic, employment and fiscal conditions could modify the estimates.

- Contingencies – The Company is subject to transactions or contingent events for which it uses professional judgment in the development of estimates of probability of occurrence. Factors that are considered in these estimates are the current legal situation at the date of the estimate and, the opinion of the legal advisers.

- Deferred income tax assets – The Company reviews the carrying amounts at the end of each reporting period and reduces deferred income tax assets to the extent that it is not probable that sufficient taxable profit will be available to allow all or part of the deferred income tax assets to be utilized. However, there is no assurance that the Company will

F-25 

generate sufficient taxable profit to allow all or part of its deferred income tax assets to be realized.

- Valuation of financial instruments –The Company has certain types of derivative financial instruments (gas swaps), and the valuation techniques that includes to determine the fair value are based in data obtained in observable markets.

The Company’s management believes that the chosen valuation techniques and assumptions used are appropriate in determining the fair value of derivative financial instruments. At December 31, 2018 and 2017 the Company has not derivative financial instruments.

6) Cash and cash equivalents and other investments

Cash and cash equivalents are as follows:

	December 31,
	2 0 1 8		2 0 1 7
Cash	$	514,166	$	1,339,887
Cash equivalents (1)		6,473,075		5,863,717
	$	6,987,241	$	7,203,604

(1) Most of these cash equivalents correspond to Treasury Bills issued by the United States Treasury Department, whose initial original maturity is less than 90 days.

As of December 31 2018, there were no temporary investments, ($ 88,947 at December 31, 2017) consisting of equity instruments for trading.

7) Trade receivables – Net

The average collection period on sales of goods is between 30 and 60 days. No interest is charged on the outstanding accounts receivables from clients. The Company has recognized an allowance for doubtful accounts to show the possible financial loss caused by the inability of customers to make the corresponding payments. Allowances for doubtful accounts are calculated based on several factors including price adjustments, likelihood of recovery, aging and historical experience.

Credit limits and scoring by customer are reviewed twice a year. On December 31, 2018 and 2017 there are no customers who represent more than 5% of the total balance of trade receivables. The Company does not hold any collateral or other credit enhancements over these balances nor does it have a legal right of offset against any amounts owed by the Company to the counterparty.

Trade receivables disclosed below include amounts that are past due at the end of the reporting period for which the Company has not recognized an allowance for doubtful debts because there has not been a significant change in credit quality and the amounts are still considered recoverable. The Company does not hold any collateral. In general terms, the accounts receivable does not show impairment.

Age of receivables that are past due but not impaired is as follows:

	At December 31,
	2 0 1 8		2 0 1 7
30 - 60 days	$	221,996	$	72,778
61 - 90 days		57,119		57,629
91 + days		188,262		162,807
Total	$	467,377	$	293,214

During the years ended December 31, 2018 and 2017, the movement in the allowance for doubtful accounts was as follows:

	2 0 1 8		2 0 1 7
Balance at beginning of year	$	199,855	$	59,095
Provisions		7,486		141,140
Translations effects		24,437		(380)
Balance at end of year	$	231,778	$	199,855

F-26 

In determining the nonrecoverable portion of accounts receivable, the Company considers any change in the credit quality of the trade receivable from the date credit was initially granted up to the end of the reporting period. The concentration of credit risk is minimum, due to the fact that the customer base is large and unrelated.

Republic made an agreement with a third party ("buyer") to carry out a factoring of accounts receivable to customers. The maximum established amount of advances related to the allocation of accounts is USD $ 30 million. The remaining amount between the received and the value of the invoices is kept in reserve by the "buyer". The payments of the funds retained in reserve minus a discount will be made by the buyer within 4 days after receiving the collection payments related to each assigned account. Said discount will be made on the total of the invoice and is in a range of 1% if the payment is made within 15 days (from the advance date) or up to 3.75% if paid within 90 days days and 1% for every additional fifteen days until the account is settled. This discount is recognized as an interest expense in the consolidated statement of comprehensive income.

The purchaser has no recourse against the Company if payments are not received due to insolvency of an account debtor within 120 days of the invoice date. However, while the facility calls for the sale, assignment, transfer and conveyance of all rights, title and interests in the selected accounts receivable, the purchaser may put and charge-back any receivable not paid to the purchaser within 90 days of purchase for any reason besides insolvency of the account debtor. As collateral for the repayment of advances for receivables sold, the purchaser has a priority security interest in all accounts receivable of the Company (as defined by the Uniform Commercial Code of the United States of America).

In 2018, the Company sold a nominal amount of USD $ 23.1 million ($25.4 million in 2017) of accounts receivable. The discount fees incurred by this contract were approximately USD $ 0.5 million in 2018 and USD$ 0.5 in 2017. These fees were included in expenses for interest in the Comprehensive Income Statement. As of December 31, 2018, and 2017 the buyer has USD$ 2.7 million and USD$ 1.9 million, respectively, of receivables that have not been recovered by the buyer. The amount uncollected for 2018 are subject to a possible return of the Company by the buyer. These accounts receivable is included in the total trade receivables for the purpose of assessing the recoverability of them and, where appropriate, determine the adequacy of allowance for doubtful accounts.

F-27 

The Company has $ 952,786 and $ 1,037,470 of coke inventory on hand as of December 31, 2018 and 2017 respectively (See note 4-e), which the Company would use as an input to its blast furnace in the Lorain facility which is currently idled. Management of the Company continually evaluates both the idled facility and the coke inventory for impairment. Management periodically evaluates the potential degradation of the coke inventory and has determined that it continues to be suitable as a blast furnace input or, alternatively, for sale to other blast furnace facilities. As of April 2019, Management expects that there will be recovery in the industries in which the Company operates; this would result in the blast furnace being restarted in the future. However, the Company has recorded an impairment to the blast furnace resulting in a book value of zero. The Company has continued incurring certain costs to maintain the assets in Lorain, including the blast furnace and the coke; such costs are expensed as incurred. In order to restart the blast furnace, the Company will incur certain expenses for the restoration of the equipment, and there is still uncertainty on the date on which the blast furnace will restart its operation. The Company cannot offer any guarantee of the restarting of the total operation of the blast furnace or when conditions will become economically feasible.

As of December 31, 2014, Republic had invested USD$158.8 million in an electric arc furnace and associated equipment at its steelmaking facility in Lorain, Ohio, USA, to meet growing customer demand for the Company's SBQ (special bar quality) steel. The location was chosen for its strategic proximity to customers and its skilled workforce. The construction of the Lorain electric arc furnace began mid-year 2012 and the Company began steelmaking operations in July 2014. The amounts above include USD $ 45.4 million capitalized from labor and manufacturing overhead related to the construction of the furnace and is presented as a component of machinery and equipment.

In June 2015, Republic Steel temporarily suspended operations in the newly constructed electric arc furnace at the Lorain facility in response to the severe economic downturn in the exploration for oil and gas sector, following the sharp drop in the price of oil which has led to significant market declines and demand for steel product, for those markets. As a consequence of this event, management determined a triggering event took place to where the long-lived assets at the Lorain facility may not be fully recoverable. Management performed an analysis of the fair value of the Lorain facility with the assistance of an independent valuation firm and determined that net book value exceeded the fair value by approximately USD$130.7 million and as such recognized an asset impairment of this amount during the year ended December 31, 2015. The fair value determination at the Lorain facility was based on an independent valuation of the assets using the comparable match method of the market approach to determine fair value. The income approach was not considered an appropriate fair value measurement due to the absence of reliable forecast data on the future behavior of oil market.

Subsequent to December 31, 2015, the entire Lorain facility was temporarily idled effective March 31, 2016 and management has no near-term plans to restart the facility, and the expectation is that it will be restarted when oil and gas market conditions improve substantially, particularly in the oil and gas drilling industry. The Company has property, machinery, and equipment with a net book value of approximately USD$ 32.7 and USD$ 32.2 million as of December 31, 2018 and 2017, pertaining to the Lorain, Ohio facility after recording the impairment charge of USD$ 130.7 million as mentioned above. The impairment charge did not impact the operations or future cash flows of the Company, as it was a provision and not a cash expenditures. Management further assessed if there were any impairments at the Company's other cash generating units and determined that as of December 31, 2016 no other cash generating units were impaired based on current projections.

Such benefits consist of a one-time payment equivalent to 12 days wages for each year of service (at the employee’s most recent salary, but not to exceed twice the legal minimum wage), payable to all employees with 15 or more years of service, as well as to certain employees terminated involuntarily prior to the vesting of their seniority premium benefit. These obligations are calculated by independent actuaries using the projected unit credit method.

c. Severance benefits – Further, in accordance with the Mexican labor laws, the Company also provides statutorily mandated severance benefits to its employees terminated under certain circumstances. Such benefits consist of a one-time payment of three months’ wages plus 20 days’ wages for each year of service, payable upon involuntary termination without just cause. Severance benefits payments are recorded directly in the consolidated statement of comprehensive income (loss) at the time they are paid, unless they are related to restructuring expenses, which are recorded when there is a present obligation from past events.

d. Employee profit sharing (EPS) – The Mexican Constitution and the Labor Law grant employees the right to receive a 10% share of the employers’ profits. Employees Profit Sharing is computed in similar terms to the taxable profit for income tax, excluding mainly the employee’s profit sharing paid this year and the amortization of tax losses and decreasing the non-deductible part of the social security for purposes of income tax. For the years 2018 and 2017, EPS amounted to $ 67 and $ 0, respectively. EPS is recorded in the results of operations for the year in which it is incurred.

e. Governmental defined contribution plan – Under Mexican legislation, the Company must make payments equivalent to 2% of its workers’ daily integrated salary (ceiling) to a defined contribution plan that is part of the retirement savings system. The expense in 2018, 2017 and 2016 was $13,687, $12,838 and $11,323, respectively.

Foreign entities (Republic)

Republic is the only subsidiary of the Company which offers other benefits and pension plans to their employees. Such benefit plans to employees are described below:

a. Collective Bargaining Agreements

As of December 31, 2018, 81% of the Republic employees are covered by a collective bargaining agreement (labor agreement) with the United Steelworkers (“USW”). The agreement initially expired on August 15, 2016 and was extended for a further three years through August 15, 2019. The extended agreement renews all the provisions, understandings and agreements set forth in the January 1, 2012 Basic Labor Agreement. The base rates of pay were determined under the extended agreement and will remain unchanged from those ruling under the expired agreement as of August 16, 2016. The extended agreement provides the Company’s quarterly contributions to fund the Republic Retirement VEBA and Benefit Trust (the “Benefit Trust”) to be reduced from $2.6 million to $0.25 million beginning in August 15, 2016 through June 30, 2019. Effective July 1, 2019, the Company’s contribution to the Benefit Trust will change to $4.00 per hour for each hour worked by USW represented employees.

b. Defined Contribution Plans

Plan for employees- Republic participates in the Steelworkers Pension Trust (SPT), a defined benefit multi-employer pension plan. The Company obligations to the plan are based upon fixed contribution requirements. Republic contributes a fixed amount of USD$1.68 per hour for each covered employee's contributory hours, as defined under the plan.

Participation in a multi-employer pension plan agreed under terms of a collective bargaining agreement differs from a traditional qualified single employer defined benefit pension plan. The SPT shares risks associated with the plan in the following respects:

I. Contributions to the SPT by Republic may be used to provide benefits to employees of other participating employers;

F-32 

II. If a participating employer stops contributing to the SPT, the unfunded obligations of the plan may be borne by the remaining participating employers; and

III. If Republic chooses to stop participating in the SPT, Republic may be obliged to pay an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

c. VEBA Benefit Trust

The Company is required to make quarterly contributions to the defined contribution plan for post-retirement health benefits VEBA as determined by the terms of the USW collective bargaining agreement. The Benefit Trust is a health and welfare plan for USW retiree benefits, and is not a "qualified" plan under the regulations of the Employee Retirement Income Security Act of 1974. For the years ended December 31, 2018, 2017 and 2016, the Company recorded expenses of USD$ 1.0 million, USD$ 6.9 million and USD$ 10.4 million, respectively, related to this benefits plan.

For the years ended December 31, 2018, 2017 and 2016, Republic recorded combined expenses of USD$ 3.6 million, USD$ 3.5 and USD$ 10.0 million, respectively, related to the funding obligations of the retirement healthcare and pension benefits. The cost contributions to these two funds have been reduced from USD $ 2.6 million to USD$ 0.25 million per quarter effective after the review of the collective agreement on August 16 2016.

d. 401(k) Plans

The Company has a 401(k) defined contribution retirement plan that covers almost all the salaried and nonunion hourly employees. This plan is designed to provide retirement benefits through Company contributions and voluntary deferrals of employees' compensation. The Company funds contributions to this plan each pay period, based on the participant's age and years of service as of January first of each year. The amount of the Company contribution is equal to the monthly base salary multiplied by the appropriate percentage based on age and years of service. The contribution becomes 100% vested upon completion of three years of vesting service. In addition, employees are permitted to make contributions to this 401(k)-retirement plan through payroll deferrals. In this case, the Company provides a 25.0% matching contribution for the first 5.0% of payroll that an employee elects to contribute. Employees are 100% vested in both their and Republic matching 401(k) contributions. For the years ended December 31, 2018, 2017 and 2016, the Company recorded expense of USD$ 1.0 million, USD$ 0.8 million and USD$ 0.7 million, respectively, related to this defined contribution retirement plan.

Employees who are covered by the USW labor agreement are eligible to participate in the 401(k) defined contribution retirement plan through voluntary deferrals of employees' compensation. There are no Company contributions or employer matching contributions relating to these employees.

e. Profit Sharing and Incentive Compensation Plans

The labor agreement includes a profit sharing plan to which the Company is required to contribute The extended agreement modified the plan to the following quarterly pretax income, as defined in the labor agreement ("EBT"): 3% of EBT between $0 and $25 million per quarter; 4% of EBT between $25 and $75 million per quarter; and 5% of EBT over $75 million per quarter. USD $ 1.0 million of expense was recorded for the year ended December 31, 2018, 2017 and 2016, because the current and prior year thresholds had not been achieved.

Republic has a profit-sharing plan for all salaried employees and nonunion workers. The profit-sharing plan was based on achieving certain EBITDA, inventory and shipments targets. In the year ended December 31, 2018, 2017 and 2016, the Company paid USD 0.8 million, USD $ 0.9 and USD $0.6 million respectively under this plan.

15) Income taxes

The Company is subject to Income Tax (ISR).

F-33 

The analysis of the income tax charged to the results of 2018, 2017 and 2016 is as follows:

	2 0 1 8		2 0 1 7		2 0 1 6
Income tax of the year for Mexican companies	$	67,745	$	19	$	6,751
Income tax year for foreign companies		444,104		44,751		60,965
Deferred tax for Mexican companies		408,141		656,060		660,916
Deferred tax for foreign companies		(167,528)		421,979		207,762
	$	752,462	$	1,122,809	$	936,394

During 2018 and 2017, the income tax expense (benefit) attributable to income was different from the one that will result for applying 30% (tax rate in Mexico) before these provisions, as a result of the losses shown below:

	2 0 1 8		2 0 1 7		2 0 1 6
Expected benefit, expense	$	1,308,828	$	890,249	$	1,591,129
Increase (decrease) as a result of:
Inflation effects, net		(114,419)		(217,249)		(62,708)
Effect between nominal rate from USA and Mexico		(35,914)		(16,572)		157,366
Benefit from utilization of tax loss carry-forward and others (1)		(1,238,444)		(115,068)		(1,165,805)
Others, net (includes permanent items)		832,411		581,449		416,412
Income tax expense	$	752,462	$	1,122,809	$	936,394
Effective tax rate (2)		17.92%		37.21%		17.68%

(1) This amount corresponds to the income tax benefit obtained by those companies that used tax loss carry-forwards in the years presented that were generated previously , less the effect of tax losses incurred by some subsidiaries for which no deferred tax asset was recorded.

The Company has tax losses in some Mexican subsidiaries which, according to the ISR law in Mexico, can be amortized to reduce taxable income generated in the next ten years. Tax losses can be updated following certain procedures established in the law.

As of November 18, 2015, the Finance Ministry (SHCP) issued a decree in which a fiscal incentive is given to those who pay income tax (ISR) under terms of the Titles II or IV, Chapter II, Section I of the Law of ISR. Taxpayers who had business income of up to 100 million pesos, could write off up to 82% of 2016 and 85% for 2017 of investment in new fixed assets. This incentive that was used by Aceros Especiales Simec Tlaxcala, S.A. de C.V. and Fundiciones de Acero Estructural, S.A. de C.V. Likewise, on January 18, 2017, a decree was issued in which similar benefits were granted but only 69% authorized as an immediate deduction, which was used by the company Simec International, S.A. de C.V.

As of December 31, 2018, Grupo Simec, S.A.B. de C.V. and certain of its Mexican subsidiaries have updated tax losses pending of amortize as follows:

Origin Date	Expiration Date	Tax losses  available
2010	2020		18,568

2014	2024		38,287
2015	2025		38,213
2016	2026		239,593
2017	2027		721,839
2018	2028		584,243
		$	10,772,446

F-34 

(1) This amount includes $ 9,014,364 corresponding to a tax loss from the sale of shares which, according to the Income Tax Law, can only be applied against taxable profits on the sale of shares generated in the future.

As of December 31, 2018, Republic had USD$ 240.2 million of tax losses pending of amortize for federal tax purposes, which expire between 2033 and 2038; USD$ 338 million of tax losses for state and local purposes that expire between 2019 and 2038 and approximately USD$ 4.7 million of tax losses at the subsidiary located in Canada, which expire between 2032 and 2037.

21) Financial instruments

a. Capital risk management – The Company manages its capital to ensure that its subsidiaries will be able to continue as a going concern while maximizing the return to its stockholders through the reinvestment of its earnings. The Company’s policy is to not obtain bank loans or any other financing transaction.

b. Market risk – Market risk is the risk that the fair value of future cash flows of a financial instrument fluctuates due to changes in market. Market prices include the exchange risk, interest rate risk and the raw material prices risk.

c. Foreign exchange risk management – The Company undertakes certain transactions denominated in foreign currencies, hence, exposures to exchange rate fluctuations arise. The exposures in exchange rate are managed within the settings of the approved policies. The book value of the monetary assets and monetary liabilities denominated in foreign currency at the end of the reporting period are as follows (includes foreign subsidiaries):

	Currency: Mexican peso
	December 31,
	2 0 1 8		2 0 1 7
Short – term assets	$	11,649,108		11,228,846
Short – term liabilities		5,567,083		4,763,682
Net monetary asset position in foreign currency	$	6,082,025	$	6,465,164
Equivalent in U.S. Dollars (thousands)	USD$	309,414	USD$	327,592

d. Credit risk management – Credit risk refers to the risk that a counterpart will default on its contractual obligations resulting in financial loss for the Company. The Company has adopted a policy of only dealing with creditworthy counterparties. The Company only transacts with entities that have a risk grade equivalent to the investment grade and higher. The Company investigates and rates its major customers. The Company exposure and the credit ratings of its counterparties are continuously monitored and the accumulated value of transactions concluded is spread amongst approved counterparties. Credit exposure is controlled by counterparty limits that are reviewed and approved annually by the risk management committee.

Trade receivables consist of a large number of customers dedicated to construction and automotive industries, distributed in different geographic areas. Ongoing credit evaluation is performed on the financial condition of accounts receivable.

The Company does not have significant credit risk exposure with any single counterparty or any group of counterparties having similar characteristics. The Company defines that the counterparties that have similar characteristics are considered related parties. Concentration of credit risk to any other counterparty did not exceed 5% of gross monetary assets at any time during the year.

The credit risk on liquid funds and derivative financial instruments is limited because the counterparties are banks with high credit-ratings assigned by international credit-rating agencies.

e. Liquidity risk and risk tables – Ultimate responsibility for liquidity risk management rests in the board of directors, which has established an appropriate liquidity risk management framework for the management of the Company’s short, medium and long-term funding and liquidity management requirements. The Group manages liquidity risk by maintaining adequate reserves, banking and credit facilities, by continuously monitoring forecast and actual cash flows, and by matching the maturity profiles of financial assets and liabilities. The following table sets out details of additional bank lines of credit (to be used as letter of credits) that the Company has at

F-40 

its disposal to reduce liquidity risk. These lines of credit are obtained by the Company and one part of them has been used for some of the subsidiaries of Industrias CH, S.A.B. de C.V.:

23) Contingencies

As of December 31, 2018, the Company has the following contingencies:

a. Pacific Steel, Inc. (PS), a subsidiary located in National City in San Diego County, California, United States of America, for which main activity is the purchase and sale of scrap, has the following environmental contingencies:

California Department of Toxic Substances Control

On September 2002, the Department of Toxic Substances Control (DTSC) inspected PS facilities based on an alleged complaint from neighbors due to PS’s excavating to recover scrap metal on its property and on a neighboring property, which PS rents from a third party (BNSF Railway). In this same month, DTSC issued an enforcement order of imminent and substantial endangerment determination, which alleges that certain soil piles, soil management and metal recovery operations may cause an imminent and substantial danger to human health and the environment; consequently, DTSC sanctioned PS for violating Hazardous Waste Control Laws in the State of California and imposed the obligation to remedy the site. On July 26, 2004, in an effort to continue with this order, DTSC filed against PS a Complaint for Civil Penalties and Injunctive Relief in San Diego Superior Court. On July 26, 2004, the court issued a judgment, whereby PS was obligated to pay USD$ 0.2 million, which has been paid.

On June 6, 2010, the DTSC and the San Diego Department of Environmental Health (DEH) inspected the facilities of PS, in response to a general complaint. On August 10, 2010 DTSC and DEH conducted a second inspection and found seven infractions. The DEH is satisfied with the compliance of PS on those issues; however, on October 19, 2010 the technical division of the DTSC recommended to the legal division of DTSC that it impose significant penalties.

The land remediation was suspended at the beginning of 2011 due to the inefficiency of the process, which was verified by several studies. As an alternative, once the necessary permits were obtained from the authorities in Mexico, the Mexicali plant began the process of importing non-RCRA soil for final disposal in a secure landfill based in Nuevo Leon State. This landfill is deposited after the separation of the metal content, which is used as raw material in the smelting process. PS has completed the shipment of non-RCRA soil for final disposal in Nuevo Leon State at this time.

The disposition of a stack estimated at 8,000 tons of material classified RCRA (hazardous for Federal purposes) was also considered for shipment to Mexico. The process began in early 2013, but the response from the authorities was slow. Therefore, on April 9, 2015, a letter from the California Attorney General Department of Justice (Attorney General) was received where PS is required to, in

F-43 

the absence of obtaining permission from the Mexican authorities; present a program for transport the pile of contaminated soil classified as RCRA to an authorized confinement in the United States at the latest on April 22, 2015. This letter warned that PS must ship the RCRA soil no later than July 9, 2015, or risk DTSC proceeding with a civil lawsuit seeking the maximum amount of fines established by law and corresponding legal redress.

On April 21, 2015, PS sent a letter to the Attorney General explaining that the authorities in Mexico had not denied permission to the Company but had simply requested that it present its application in a different format, which had already been presented and reviewed by the authority on April 17, 2015.

On July 23, 2015, the Attorney General denied the extension requested by PS and demanded the immediate shipments of the RCRA stack to an authorized landfill. PS began transporting RCRA soil on July, 29, 2015, and completed removal of the RCRA stack by September 12, 2015 with a total of 3,000 metric tons.

On January 5, 2016, the Attorney General and PS stipulated to filing a "final judgment and order on consent" or Consent Judgment in San Diego Superior Court. The parties negotiated the Consent Judgment, which includes the following terms:

- PS to pay USD$ 0.138 million as a civil penalty for alleged violations of the 2004 Corrective Action Consent Agreement. PS has made all of the required payments to DTSC as of December 31, 2017.

- Remove the RCRA soil pile and send it to an approved landfill. The Judgment indicates that the Company complied with this commitment by October 2, 2015.

- After removing the RCRA soil pile, the Company must take samples of the soil in the area where the RCRA soil pile was located. Samples were taken and the results indicated that the soil had pollution levels that exceed the limits set by the State. On April 7, 2016, the Attorney General and DTSC demanded that the Company remove soil 10 feet across and 2 feet deep on the perimeter of the area where the RCRA soil pile was located and dispose of it in an approved confinement. Instead, PS convinced DTSC to enter into a Tolling Agreement on August 10, 2016, which tolls for two years (until August 10, 2018) the statute of limitations for DTSC to challenge PS’s compliance with the Consent Judgment. This Tolling Agreement was extended on August 10, 2018, for an additional two-year period. This Tolling Agreement remains in force as of December 31, 2018, and will end as of August 10, 2020.

- The Company shall continue to meet the conditions of the final judgment, the corrective measures, and all tasks arising from this, which were entered in the same court in 2004.

PS is working to develop a “corrective measures study” (CMS) that is intended to develop a plan for determining what remedy will be implemented at the site. As of December 31, 2018, it is unclear what will be the appropriate remedy to implement at the PS site, when the CMS will be completed, how long remediation will take, and how much it will cost.

b. As with most steel producers in United States of America, Republic could incur significant costs related to environmental issues in the future, including those arising from environmental compliance activities and remediation stemming from historical waste management practices at the Republic’s facilities. The reserve created to cover probable environmental liabilities of USD$ 2.6 million and USD$ 2.7 million were recorded as of December 31, 2018 and 2017, respectively. The reserve includes incremental direct costs of remediation efforts and post-remediation monitoring costs that are expected to be paid after corrective actions are complete. As of December 31, 2018, the current and non-current portions of the reserve amounted to USD$ 1.0 million and USD$ 1.6 million, (USD$ 1.0 million and USD$ 1.7 million in 2017), respectively, are included in accounts payable and accumulated liabilities in the short and long term, respectively, in the Consolidated Statements of Financial Position.

c. The Company is not aware of any material environmental remediation liabilities or contingent liabilities relating to environmental matters with respect to facilities, for which the establishment of an additional reserve would be necessary at this time. In the event that, in the future, the Company incurs in any such additional expenses, these costs will most likely be incurred over a number of years. However, future regulatory action regarding historical waste management practice in the

F-44 

facilities of Republic PS and future changes in applicable laws and regulations may require the Company to incur significant costs that may have a material adverse effect on the future financial performance of the Company.

d. The Company is involved in a series of lawsuits and legal claims that have arisen during the normal course of its operations. The Company and its legal advisors do not expect the outcome of these matters to have any significant adverse effect on the Company's financial position and results of operations, therefore it has not been recognized any liabilities for such lawsuits and claims.

e. Mexican tax authorities have the right to review, at least the previous five years and could determine differences in taxes payable, plus any corresponding adjustments, surcharges and fines.

f. Tax authorities in United States of America have the right to review, at least the previous three years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines.

g. Canadian tax authorities have the right to review, at least the previous four years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines.

h. Brazilian tax authorities have the right to review, at least the previous five years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines.

i. On January 19, 2017, the Company was notified with the excerpt issued by the General Direction of Crimes and Sanctions of the National Banking and Exchange Commission (CNBV), for the probable realization, in the re-purchase of own stock operations, of several behaviors that, under the judgment of the CNBV, could be different to the ones established in the “Ley del Mercado de Valores (LMV)”. On February 9, 2017 Grupo Simec filed the statement of manifestations to the administrative sanction procedure. The resolution was favorable for the company, issued on May 15, 2018.

On September 5, 2017, Grupo Simec and GV do Brasil were notified of the arbitration procedure filed by SMS Concast at the International Court of Arbitration (ICC), which claims the payment of USD $ 1.4 million plus expenses, for the concept of additional costs, incurred in the construction and assembly of the steelmaking area of the Brazilian plant. On November 6, 2017, the companies of the Group replied to the demand and filed a counterclaim against SMS Concast for the amount of USD $ 5 million, which GV do Brasil utilized on the equipment to work properly. The panel of arbitrators is already constituted and the resolution of the matter is in process.

j. In February 2017, the Securities and Exchange Commission ("SEC") notified the Company of the opening of an investigation to determine if the Company's management committed infractions of US federal securities laws related to the failure to maintain internal control over financial reporting. This investigation is derived, in part, from the failures in these systems which were reported in the 20-F (Annual Report) for the fiscal year 2015. On February 21, 2016, the Company began implementing the corrective measures recommended by a specialist firm in order to better comply with the COSO framework. On January 29, 2019, the Company reached a settlement with the SEC. Under the terms of the settlement, the Company paid a civil penalty of USD $200,000 and retained an independent consultant to ensure remediation of material weaknesses and the implementation and maintenance of internal controls over financial reporting. The Company’s remediation efforts continue.

k. During the year 2018 Grupo Simec and some of its subsidiaries have been audited by the tax authorities of Mexico with respect to fiscal years from 2013 to 2017. The tax which the authority pretends to impose are non-existent taxes, which we have been litigating through various means including “amparo”, lawsuits, resources of revocation in some cases and nullity lawsuit in others. As of December 31, 2018 the payment has not been enforceable in any of the disputed matters. The amount of tax credits being appealed in court ascends to $ 5,880 million.

24)  Retrospective restatement of the 2016 and 2017 financial statements.

During 2018, the Company identified certain misstatements in the financial statements as of and for the years ended December 31, 2017 and 2016. The Company has restated the balances and results for these periods as presented in the report in accordance with the guidance of IAS 8 – Accounting Policies, Changes in Accounting Estimates and Errors.

These involuntary errors were specifically that significant information related to transactions was not available to the accounting staff in regards to some non-routine transactions. This lack of timely,

F-45 

accurate information lead to incorrect accounting treatments and misstatements to the financial statements.

These errors relate to the recording of advances made to related parties and the accrual of related interest income.

For this reason, the accrued interest and the related income tax effect of certain loans granted to related parties were not previously recognized in the Company’s financial statements. The interest to be recognized through the restatement is as follows:

Company name	Balance as of December 31st, 2016	2016 Recognized Interest	2017 Recognized Interest

Earnings per share before correction		$ 5.93	$ 3.49
Earnings per share after correction		$ 5.97	$ 3.84

There were additional errors identified in the presentation of accounts and loans receivable with related parties in the 2016 and 2017 financial statements. These errors relate to the classification of certain balances as short-term assets which are long-term assets. There were additional corrections related to the reclassification of certain accounts payable to loans payable.

The balances of related parties that were corrected through reclassification from the short-term assets to the long-term asset (after recording the interest described above) were:

25) Commitments

a. On May 1, 2018, the Company signed a contract with ArcelorMittal S.A. in Brazil, for the acquisition of Cariacica and Itauna steels for rent, producing plants and wire drawing equipment for the production of wires and derivatives.

The Cariacica unit has the capacity to produce 600 thousand metric tons of liquid steel per year and 450 thousand metric tons of rolled steel products. This plant has more than 500 employees and can produce rod and light structural profiles. The factory is located in the city of Cariacica, next to the city of Victoria, in the state of Espírito Santo on a land of more than 1,200,000 m2.

The Itauna unit has an installed capacity to produce 120,000 metric tons per year of steel laminate products and can manufacture light structural profiles and rods. The plant is located in the city of Itauna in the state of Minas Gerais, less than 100 kilometers away from Belo Horizonte and has 94 employees. The factory is leased under a contract expiring in August 2020.

b. Republic leases certain equipment, office space and computer equipment under non-cancelable operating leases. The leases expire at various dates through 2020. During the years ended December 31, 2018, 2017 and 2016, rental expenses relating to operating leases amounted to USD$ 0.7 million, USD$ 0.5 million, and USD$ 1.1 million, respectively. Currently there are no additional obligations post-2020.

c. In January 2013, the Company entered into an agreement with EnerNOC which enables Republic to receive payments for reducing the electricity consumption during a dispatch declared by PJM Interconnection as an emergency. The agreement is for 5 years, effective January 31, 2013 and expires on May 31, 2018. During the years ended December 31, 2018, 2017 and 2016, the Company recognized income from this agreement of USD$ 2.8 million, USD$ 1.0 million and USD$ 1.0 million, respectively. Unlike the previous contract the payments are earned by event and how they accrue.

d. In January 2013, the Company signed a product supply agreement for 15 years with Air Products and Chemicals, Inc. The agreement required that Air Products and Chemicals build and install a plant for the production of oxygen, nitrogen, and argon in the facilities of Lorain, Ohio. The term of 15 years of this agreement would come into force at the time the plant becomes operational. The plant did not start operations as indicated in Note 10. In August 2016, the Company signed a new agreement with Air Products and Chemicals, Inc., to acquire the previously installed plant, for an amount of USD $ 30 million and cancel in its entirety the supply contract. The amount of the purchase was agreed to settle it in the following way: an initial payment of USD $ 1.2 million and the remaining of USD $ 28.8 million over a period of 6 years with monthly payments equal to USD $ 0.4 million, without any interest payment.

e. In connection with a sales and use tax audit by the Ohio Department of Taxes covering the period from January 1, 2009 to December 31, 2012, an assessment of $ 2,452,028 (including interests of $ 394,138) against the Company was issued, on December 9, 2016. The Company does not agree with the evaluation in its entirety and has filed a Reevaluation Petition on January 30, 2017 appealing the assessment to the Ohio Board of Tax Appeals. As of July 30, 2019, no resolution has been obtained on this appeal.

Due to the nature of this matter and the uncertainty of the resolution on the appeal that is in the early stages, the Company has not recorded an expense in the fiscal year 2018 or 2017 that recognizes the evaluation or any estimated amount of liquidation.

f. In January 2018, the Company entered into a contract with the supplier ECOM, LTDA. for an amount of USD $ 6.1 million for the purchase of energy of 10,000 MWH per month, for its subsidiary GV do Brasil Industria y Comercio de Aço LTDA.

F-51

Application of new and amended standards and interpretations and standards not in force yet

3. Application of new and amended standards and interpretations and standards not in force yet

The consolidated financial statements of Grupo Simec, S.A.B. de C.V. and its Subsidiaries for the periods presented have been prepared in accordance with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB). IFRS also includes all current International Accounting Standards (IAS), in force, as well as all related interpretations issued by the IFRS Interpretations Committee (IFRIC), including those issued previously by the Standing Interpretations Committee. The company applied the effective IFRS as of December 31, 2018.

a.        International Financial Reporting Standards, not in force yet.

Below are the rules and amendments that could have an effect on Simec's financial information, which were issued by the IASB, but are not in effect at the date of these financial statements

Rules applicable starting from 2018:

a)   IFRS 15- Revenue from contracts with customers.

The IASB has published a new standard, IFRS 15- Income from contracts with customers (IFRS 15 or the new standard). The new standard describes a single comprehensive model for accounting of revenue from customer contracts and replaces current revenue recognition guidelines included in IFRS standards and interpretations.

The basic principle of the new rule is that an entity must recognize the income that represents the transfer of goods or services promised to the client, valued by the amount that the entity expects to receive in exchange for such goods or services.

The entities must:

• Identify the contracts with clients which are within the scope of the new standard;

• Identify the performance obligations in the contract: i) sales of goods or services separately, ii) sales dependent or interrelated with other products or services; (iii) homogeneous and consistent sales;

• Determine the price of the transaction: i) variable consideration and restricted estimates, ii) time value of money and financing component, iii) non-monetary consideration, iv) consideration paid to the customer;

• Distribute the transaction price among each separable performance obligation; and

• Recognize income when each performance obligation is met: (i) over time, (ii) at a point in time.

The new IFRS 15 increases disclosures on income and is effective for periods beginning on or after January 1, 2018, allowing for early application. Entities may choose to retroactively apply the standard or use a modified approach in the year of application.

b) IFRS 9 (2014) - Financial Instruments.

The IASB published IFRS 9 (2009) and IFRS 9 (2010) which introduced new classification and valuation requirements, and in 2013 disclosed a new model for hedge accounting. IFRS 9 published in July 2014 represents the final version of the standard, supersedes previous versions of IFRS 9, and completes the IASB project to replace IAS 39, Financial Instruments.

IFRS 9 (2014) includes a logical model for classification and valuation, a single, forward-looking model of impairment, and an approach with substantive changes to hedge accounting.

Classification and valuation

The classification determines how financial assets and financial liabilities are recorded in the financial statements and, in particular, how they are valued continuously. IFRS 9 (2014) introduces a logical approach to the classification of financial assets, which is based on the flow characteristics and the business model in which the asset is held. This unique, principled approach replaces existing requirements.

Impairment

The new model results in the application in a single model of impairment to all financial instruments, thus eliminating a source of complexity associated with the previous requirements. As a part of IFRS 9 (2014), IASB has introduced a new impairment model based on expected losses, which will require a timelier recognition of expected losses. Specifically, the new standard requires entities to recognize expected losses since the initial recognition of financial instruments as well as over the life of the instrument on a timelier basis. Further disclosures will be required on how the losses and the movement of the loss estimate were determined and of the activity of the estimate for losses.

Hedge Accounting

IFRS 9 (2014) introduces an approach with substantive changes for hedge accounting, with improvements to disclosures about risk management activities. The new model represents a major overhaul of hedge accounting, which aligns accounting manage with risk management activities, allowing entities to better reflect these activities in their financial statements. In addition, as a result of these changes, users of financial statements will be better informed about risk management and the effect of hedge accounting on financial reporting.

Own credit risk

IFRS 9 (2014) also eliminates the volatility in results that was caused by changes in the credit risk of liabilities that are valued at fair value. This accounting change means that gains proceeding from the impairment of the risk of our credit on these liabilities are no longer recognized directly in net earnings or loss but in other comprehensive income (OCI).

IFRS 9 (2014) will come into force for fiscal years beginning on or after January 1, 2018. Early application is allowed. In addition, changes in credit risk can be applied in advance and in isolation, without the other changes in the recognition of financial instruments.

Amendments applicable from 2018

a) Amendment to IAS 40 - Investment Property.

The amendment clarifies that the transfer of an investment in property will occur when and only when there is a change in its use. A change of use occurs when the property meets, or fails to meet, the definition of investment property and there is evidence of change of use. In isolation, a change in management's intentions to use a property does not provide evidence of a change in use.

b) Amendment to IAS 28 - Investments in Associates and Joint Ventures.

This amendment clarifies that a venture capital organization, collective investment fund, investment trust and other similar entities may opt, at initial recognition, to measure investments in associates and joint ventures at fair value through changes in profit and loss separately for each associate and joint business.

In addition, this amendment allows, in applying the equity method, that an entity other than an investment entity retains the measurement of the fair value applied by its associates and joint ventures. It also clarifies that this option is available at the initial recognition for each associate or joint venture that is an investment entity.

c) Amendments to IFRS 2 - Classification and measurement of share-based payment transactions.

The amendments clarify the following:

• When estimating the fair value of a share-based payment settled in cash, accounting for the effects of the acquisition conditions and the liability incurred should follow the same approach as for stock-based share-based payment.

• Where tax laws or regulations require an entity to withhold an amount because of an employee's tax liability associated with a share-based payment, the share-based payment arrangements may allow or require to retain a specified number of equity instruments Equivalent to the monetary value of the employee's tax liability, that is, the share-based payment arrangement has a "net settlement characteristic", if the agreement does not include the net settlement characteristic, that agreement should be classified as a whole Transaction with share-based payments settled with equity instruments.

• A share-based payment that is modified to change the settlement transaction in cash to the settlement of capital, should take into account the following:

i. The original liability is written off;

ii. The share-based payment with share liquidation is recognized on the date of modification of the fair value of the equity instrument granted to the extent that the services had been rendered until the date of modification; and

iii. Any difference between the carrying amount of the liability at the date of change and the amount recognized in the net equity must be recognized immediately in profit or loss.

Amendments are effective for annual reporting periods beginning on or after January 1, 2018 with anticipated permitted application.

Interpretation applicable from 2018:

a) IFRIC 22- Transactions in foreign currency and considerations paid in advance.

IFRIC 22 Interpretation, issued by the International Accounting Standards Board, developed by the IFRS Interpretations Committee, addresses how to determine the date of the transaction for the purpose of establishing the exchange rate to be used in the initial recognition of the asset, expense or related income on the write-off of a non-monetary asset or non-monetary liability arising from the payment or collection of the anticipated consideration in foreign currency.

It is established that the date of the transaction for the purpose of determining the exchange rate to be used in the initial recognition is the date on which an entity initially recognizes the non-monetary asset or non-monetary liability arising from the payment or collection of the anticipated consideration. If there are multiple payments or prepayments, the entity will determine a date of the transaction for each payment or collection of the anticipated consideration.

Standard applicable from 2019:

In January 2016, the IASB published a new accounting standard, IFRS 16 - Leases, which repeals IAS 17 - Leases and the related interpretation guides.

The main changes in relation to the previous rule are:

i. IFRS 16 provides a comprehensive model for the identification of lease contracts and their treatment in the financial statements of tenants and landlords.

ii. The new standard applies a control model for the identification of leases, distinguishing between leases and service contracts based on whether there is an asset identified and controlled by the customer.

iii. The distinction between operating and finance leases is eliminated; therefore, the assets and liabilities of all leases are recognized, with some exceptions, for leases of short-term low-value assets.

iv. The standard does not include significant changes in the requirements for the lessor's accounting.

The standard is effective for annual periods beginning on or after January 1, 2019, with early application permitted for entities that have also adopted IFRS 15- Income from Contracts with Customers.

As of today, Simec continues to evaluate the effect that this new standard could have on its financial statements.

Amendments applicable from 2019:

a) Amendment  to IFRS 28 - Long-term investments in associates and joint ventures.

This amendment clarifies that entities will account for long-term investments in an associate or joint venture (to which the equity method is not applied), using IFRS 9 before accounting for losses or losses due to impairment, applying IAS 28.

b) Amendment  to IFRS 3 - Business combination.

This amendment clarifies that when an entity obtains control of a business that is a joint operation, it will measure again the participation maintained in that business.

c) Amendment to IFRS 11 - Joint agreements.

This amendment clarifies that when an entity obtains joint control of a business that is a joint operation, it will measure again the participation maintained in that business

d) Amendment  to IAS 12 - Income tax.

This amendment clarifies that an entity will account for all the consequences of dividends on income tax in the same way, regardless of how the tax arises.

e) Amendment  to IAS 23 - Costs for loans.

This amendment clarifies that when an asset that meets the requirements to be suitable for its intended use or sale, an entity will treat as part of the general loans, the outstanding loans taken to obtain that eligible asset.

f) Amendment  to IAS 19 - Benefits to employees.

This amendment requires that when a change occurs in the plan (modification, reduction or liquidation), the company remeasures its liability or assets for net defined benefits. Previously, it was not specified how to determine the expenses for the period after the change in the plan. The amendments require an entity to use the updated assumptions of the new measurement to determine the current cost of the service and the net interest for the remainder of the reporting period after the change to the plan.

The amendments are effective for annual reporting periods beginning on January 1, 2019, with early application allowed.

Interpretation applicable from 2019:

IFRIC 23 - Uncertainty regarding the treatment of income tax.

The IFRIC 23 interpretation, issued by the International Accounting Standards Board, developed by the IFRS Interpretations Committee, adds to the requirements of IAS 12 - Income taxes, the specification of how to reflect the effects of the uncertainty in accounting for income tax, when it is unclear how to apply tax laws to a particular transaction or circumstance, or it is unclear whether a tax authority will accept the treatment of an entity.

This interpretation will apply for the annual reporting periods that begin as of January 1, 2019, with early application allowed.

Amendments applicable from 2020:

a) Conceptual Framework

In March 2018, the IASB issued a new revised version of the conceptual framework for financial information. The Conceptual framework for financial information contains updated definitions of assets and liabilities in the financial statements. In addition, new concepts and guidance have been added to the following topics:

i. Measurement, including the factors to be considered when selecting a measuring base.

ii. Presentation and disclosure, including when to classify income and expenses in other comprehensive income.

iii. The reporting entity.

iv. When the asset and liabilities are eliminated from the financial statements.

The conceptual framework also clarifies the roles of management, prudence, and uncertainty of measurement in financial reporting.

Several IFRSs have also been amended for references to the conceptual framework. The amendments to the IFRS for changes to the conceptual framework, update some of these references and quotations to refer to the conceptual framework for financial reporting issued in 2018 and makes other amendments to clarify what version of the Conceptual framework is mentioned in each document.

b) Amendment to IFRS 3 – Business combination.

This amendment clarifies the definition of a business, with the objective of helping entities determine whether a transaction should be accounted for as a business combination or as an acquisition of assets. The amendment consists of the following:

I. It clarifies that, in order to be considered a business, an acquired set of activities and assets must include at least a contribution and a substantive process, which together contribute significantly to the ability to create products.

II. Eliminates the evaluation of market participants to determine if they are able to replace any missing inputs or processes and continue to produce products.

III. Adds guidance and illustrative examples to help entities determine whether a substantive process has been acquired.

IV. Restricts the definitions of a business and products by focusing on the goods and services provided to customers and eliminating the reference to the ability to reduce costs.

V. Adds an optional concentration test that allows for a simplified assessment of whether an acquired set of activities and assets is not a business.

c) Amendments to IAS 1 - Presentation of financial statements and IAS 8 - Accounting policies, changes in estimates and accounting errors.

These amendments clarify the definition of "Material" and, consequently, modifications are made to a number of other standards by the definition of Material.

The amendments improve the understanding of the definition of material to: 

I. Align the drafting of the definition in the IFRS standards and the conceptual framework, to avoid the possibility of confusion arising from different definitions. 

II. Incorporate the support requirements in IAS 1, in the definition to give them greater importance and clarify their applicability; and 

III. Provide existing information on the definition of Material, along with the definition.

Simec is evaluating the impact that these changes could have on their financial statements.

Disclosure of basis of preparation and presentation of the financial statements [Abstract]

Basis of preparation and presentation of the financial statements

4) Basis of preparation and presentation of the financial statements

The consolidated financial statements have been prepared in accordance with IFRS as discussed in Note 3, based on historical costs. Historical cost is generally based on the fair value of the consideration given in exchange for assets.

Consolidation basis – The consolidated financial statements include the financial statements of Grupo Simec, S.A.B. de C.V. and the entities controlled by the Company (its subsidiaries). Control is obtained when the company possesses the power to govern the financial and operative policies of an entity in order to obtain benefits from its activities. The results of subsidiaries acquired or sold during the year are included in the consolidated financial statements from the date of acquisition or up to the date of sale, as the case may be. Total comprehensive income (loss) of subsidiaries is attributed both to the Company and to the non-controlling interests even if the non-controlling interests have a deficit balance reflecting allocated losses.

Within the consolidation process, adjustments are made to the financial statements of the subsidiaries to adapt their accounting policies so that they are aligned with those used by the Company. All significant intercompany transactions and balances between companies are eliminated during consolidation.

Changes in investments in subsidiaries of the Company that do not result in a loss of control are recorded as equity transactions. The book value of the company's non-controlling investments and shares is adjusted to reflect changes in the corresponding investments in subsidiaries. Any difference between the amount by which non-controlling shares are adjusted and the fair value of the consideration paid or received is recognized directly in the estate and is attributed to the owners of the company.

When the company loses control of a subsidiary, the profit or loss in the provision is calculated as the difference between (i) the sum of the fair value of the consideration received and the fair value of any retained participation and (ii) the value in Previous books on assets (including commercial credit) and liabilities of the subsidiary and any non-controlling participation. The amounts previously recognized in other comprehensive income items related to the subsidiary are recorded (that is, reclassified to profit or loss or transferred directly to retained earnings) in the same manner established for the case of the disposal of significant assets or liabilities. The fair value of any investment retained by the former subsidiary on the date of loss of control is regarded as the fair value for initial recognition in its subsequent accounting treatment, according to IAS 39, financial instruments: Recognition and valuation, or, where appropriate, the cost in the initial recognition of an investment in an associate or entity under joint control.

As of December 31, 2018, and 2017, the subsidiaries of Grupo Simec, S.A.B. de C.V. included in the consolidation are the following:

Summary of the main accounting policies –The preparation of the attached consolidated financial statements requires the company's management make certain estimates and use certain assumptions to value some of the items in the financial statements and to make the disclosures required in the same. However, actual results may differ from these estimates. The Company’s management, using its professional judgment, believes that the estimates made and assumptions used were adequate under the circumstances. The significant accounting policies of the Company are those mentioned below:

a. Conversion of foreign subsidiaries financial statements – The functional and reporting currency of the Company is the Mexican peso ($). The financial statements of foreign subsidiaries were translated to Mexican pesos in accordance with International Accounting Standard (IAS) 21, The Effects of Changes in Foreign Exchange Rates. Under this standard, the first step to convert financial information from operations abroad is the determination of the functional currency. The functional currency is the currency of the primary economic environment of the foreign operation or, if different, the currency that mainly impacts its cash flows.

The U.S. dollar (US Dollar or USD$) was considered as the functional currency of all the U.S. subsidiaries and Brazilian Real for subsidiaries established in Brazil; therefore, the financial statements of these subsidiaries abroad were converted to Mexican pesos applying:

- The exchange rates at the balance sheet date, to all assets and liabilities.

- The historical exchange rate at stockholders’ equity accounts and revenues, costs and expenses.

The conversion differences are carried directly to the consolidated statements of comprehensive income as other comprehensive income under the caption translation effects of foreign subsidiaries.

Relevant exchange rates used in the preparation of the consolidated financial statements of foreign subsidiaries were as follows (Mexican pesos per one U.S. dollar):

Current exchange rate as of December 31, 2018	19.66
Current exchange rate as of December 31, 2017	19.74
Average exchange rate for the year ended December 31, 2018 (*)	19.23
Average exchange rate for the year ended December 31, 2017 (*)	18.94
Current exchange rate as of April, 9 of 2019	18.97

(*) Average exchange rate used to translate revenues, costs and expenses of the companies mentioned above.

b. Business combinations – Acquisitions of subsidiaries and businesses units are accounted for using the acquisition method. The consideration for each acquisition is valued at its fair value on the date of exchange of the transferred assets, liabilities incurred or assumed and capital instruments issued by the Company in exchange for control of the acquired. The costs related to the acquisition are recognized in the results when incurred.

At the date of acquisition, the identifiable assets acquired and the liabilities assumed are recognized at their fair value, except:

- Deferred tax assets or liabilities and liabilities or assets related to employee benefit arrangements, which are recognized and measured in accordance with IAS 12, Income Taxes, and IAS 19, Employee Benefits, respectively.

- Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5, Non-current Assets Held for Sale and Discontinued Operations, are measured in accordance with that Standard.

Any excess of the cost of acquisition for the Group's interest in the net fair value of the identifiable assets, liabilities and contingent liabilities of the associated company recognized at the date of acquisition is recognized as goodwill. Goodwill is included in the carrying amount of the investment and is assessed for impairment annually. Any excess of the Group's interest in the net fair value of the assets, liabilities and contingent liabilities over the cost of acquisition, after the reassessment, is immediately recognized in profit and loss.

When the consideration transferred by the Company in a business combination includes assets or liabilities resulting from a contingent consideration arrangement, the contingent consideration is measured at its acquisition-date fair value and later adjustments to the consideration are recognized against goodwill, providing that it has arisen from reliable information on the fair value at the acquisition date and occur during the ‘measurement period’ (which cannot exceed one year from the acquisition date). All other subsequent adjustments are recognized in profit or loss.

The subsequent accounting for changes in the fair value of the contingent estimates that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates. Contingencies classified as assets or liabilities are remeasured at subsequent reporting dates in accordance with IAS 37, Provisions, Contingent Liabilities and Contingent Assets, as appropriate, with the corresponding gain or loss being recognized in profit or loss.

When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree are remeasured to fair value at the acquisition date (i.e. the date when the Company obtains control) and the resulting gain or loss, if any, is recognized in profit or loss. Amounts arising from interests in the acquiree prior to the acquisition date that have been previously recognized in other comprehensive income (loss) are reclassified to profit or loss where such treatment would be appropriate if that interest were disposed of.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date.

c. Cash and cash equivalents and temporary investments – Cash consists of deposits in bank accounts that do not generate interest. Cash equivalents consists in temporary investments referred to as short-term fixed income investments whose original maturity is less than three months. These investments are reported at cost plus accumulated interest. The value so determined approximates their fair value.

Temporary investments in equity instruments are measured at the fair value prevailing at the date of the financial statements. Subsequent changes in the fair value are recognized in profit or loss.

d. Allowances for doubtful accounts – The Company follows the practice of recording an estimation of an allowance for doubtful accounts, which is determined by considering the balances of clients with more than a year old, those in litigation and or specific recovery problems. Actual results may differ materially from these estimates in the future.

e. Inventories and cost of sales – Inventories are stated at the lower of cost or net realizable value. The cost allocation formula used is the average cost. The cost includes acquisition costs of materials, labor and overhead costs related to manufacturing and distribution, based on normal activity levels. The net realizable value represents the estimated selling price for inventories less all estimated costs of completion and other necessary to make the sale, which is recorded in the statement of financial position and against account is the cost of sales.

The Company classifies raw material inventory in the Consolidated Statements of Financial Position based on its expected consumption period, presenting as long-term inventories those which in accordance with historical data and production trends will not be consumed in the short-term (one year).

The Company classified as long-term inventory certain parts and rollers that, according to historical data and trends, showing that such inventories will not be consumed in the short-term. The Company utilizes coke, a form of coal, as a raw material input to fuel its blast furnace which has been inactive in Lorain, Ohio USA plant (see Note 9). The Company has 136,541 metric tons (MT) of coke inventory valued at 953 million Mexican pesos (average of USD$ 355/MT) on hand at December 31, 2018 and 136,541 MT of coke inventory valued at 1,037 million Mexican pesos (average of USD$ 385.00/MT) on hand at December 31, 2017 that is classified as long-term in the accompanying Consolidated Statements of Financial Position.

The Company follows the practice of providing a reserve for slow-moving inventory, considering the total of products and raw materials (including coke) with a turnover above one year, which is recorded in the statement of financial position and against account is the cost of sales.

The cost of sales of the Company includes inventory costs, outbound freight charges, purchasing and receiving costs, inspection costs, and warehousing costs in cost of goods sold. Vendor payment incentives are recorded as a reduction to cost of goods sold.

f. Property, plant and equipment – Property, plant and equipment are recorded at acquisition cost less any recognized impairment loss. Cost includes all expenses related with acquisition and installation and, for qualifying assets, borrowing costs (interest) capitalized in accordance with the Company’s accounting policy. Depreciation is recognized so as to write off the cost of assets (other than land and properties under construction) less their residual values over their useful lives, using the straight-line method, and commences when the assets are ready for their intended use. The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period, with the effect of any change in estimates accounted for on a prospective basis.

An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in profit or loss.

The initial estimated useful lives of the Company’s main assets are as follows:

Repair and maintenance costs that significantly increase productive capacity or extend the useful lives of existing plant and equipment are capitalized. Supplies, comprising of spare parts and consumables for internal use are classified under property, plant and equipment and expensed as incurred in the manufacturing process. All other repair and maintenance costs are expensed as incurred. Capital expenditures for projects that cannot be put into use immediately are included in constructions and machinery in-progress. When constructions and machinery in-progress are completed, they are transferred to depreciable assets.

g. Leases – Leases are classified as financial leases when the terms of the lease contract substantially transfer to tenants all the risks and benefits inherent in the property. All other leases are classified as operating leases.

Operating lease payments are recognized as an expense on a straight-line basis over the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred.

In the event that lease incentives are received to enter into operating leases, such incentives are recognized as a liability. The aggregate benefit of incentives is recognized as a reduction of rental expense on a straight-line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.

h. Costs for loans – Costs for loans directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are ready for their intended use or sale.

Investment income earned on the temporary investment of specific loans pending their expenditure on qualifying assets is deducted from the costs for loans eligible for capitalization.

All other costs for loans are recognized in profit or loss in the period in which they are incurred.

i. Intangible assets – Intangible assets with definite useful lives that are acquired separately are carried at cost, less accumulated amortization and accumulated impairment losses. Amortization is recognized on a straight-line basis over their estimated useful lives. The estimated useful life and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for, on a prospective basis. Intangible assets with indefinite useful lives that are acquired separately are carried at cost less accumulated impairment losses.

Expenditure on research activities is recognized as an expense in the period in which it is incurred.

An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognized if, and only if, all of the following have been demonstrated:

- The technical feasibility of completing the intangible asset so that it will be available for use or sale;

- The intention to complete the intangible asset and use or sell it;

- The ability to use or sell the intangible asset;

- How the intangible asset will generate probable future economic benefits;

- The availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and

- The ability to measure reliably the expenditure attributable to the intangible asset during its development.

The amount initially recognized for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally-generated intangible asset can be recognized, development expenditure is recognized in profit or loss in the period in which it is incurred. Subsequent to initial recognition, internally-generated intangible assets are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss.

j. Goodwill – Goodwill arising on a combination of business is carried as an asset at cost as established at the date of acquisition of the control of the business less accumulated impairment losses, if any. For the purposes of impairment testing, goodwill is allocated to each of the Company’s cash-generating units that would be expected to benefit from the synergies of the combination. A cash-generating unit to which goodwill has been allocated is tested for impairment annually, or more frequently when there is indication that the unit may be impaired. If the recoverable amount of the cash-generating unit is less than it´s carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro rata based on the carrying amount of each asset in the unit. An impairment loss recognized for goodwill is not reversed in subsequent periods. On disposal of the relevant cash-generating unit, the attributable amount of goodwill is included in the determination of the profit or loss on disposal.

k. Impairment of tangible and intangible assets other than goodwill – At the end of each reporting period, the Company reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any of such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified. Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually, and whenever there is an indication that the asset may be impaired. Recoverable amount is the higher of fair value less costs to sell and value in use. 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 for which the estimates of future cash flows have not been adjusted. If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than it´s carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease. Where an impairment loss subsequently reverses, the carrying amount of the asset (or a cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. For purposes of allocation of goodwill when there is business combination will be distributed among each of the cash generating units of the acquiring entity, expected synergy benefits. A reversal of an impairment loss is recognized immediately in profit or loss and allocated to the assets of that unit, the carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss of value shall not exceed the carrying amount that would have been obtained if had not recognized an impairment loss in value for the asset in prior periods. Unless the related asset is recognized at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase.

l. Provisions – Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that the Company will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the balance sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, it´s carrying amount is the present value of those cash flows.

m. Employee benefits – The costs of direct benefits and defined benefit and defined contribution retirement plans are recognized as an expense when employees have rendered service entitling them to the right to receive those benefits.

The retirement benefit liability is determined based on the present value of the defined benefit obligation at the date of the statement of financial position. Any compensation included in the determination of the liability premiums corresponds to seniority premiums for retirement. Actuarial gains and losses are recognized on profit or loss for the year. The retirement benefit liability and the related net cost of the period are determined under the Projected unit credit method based on projected salaries and certain assumptions determined by independent actuaries.

Liabilities for employee benefits recognized in the consolidated statement of financial position represent the present value of the defined benefit obligation.

Republic operates various employee benefit plans. The contributions to these benefit plans are either contractually determined by the terms of a collective bargaining agreement with the United Steelworkers or they are under the terms of a defined contribution plan. Accordingly, the company pays fixed contributions to separate entities and they are expensed in the period in which the employees rendered the services entitling them to the benefits.

n. Earnings per share – Income per share is calculated by dividing net income related to the controlling interests, by the weighted average shares outstanding during each year presented.

o. Income taxes – Income taxes represents the sum of the tax currently payable and deferred tax.

- Current tax – The Company incurs Income Tax (ISR) (See note 15) which is recorded in the result in the year in which it is determined. Determined ISR is based on fiscal earnings. Fiscal earning differs from the gain reported in the Consolidated Comprehensive Income Statement, due to taxable income or deductible expenses in other years and items which are never taxable or deductible. The tax liability for the Company is computed using statutory rates promulgated or substantially approved at the end of the period on report.

- Deferred tax –Deferred tax is recognized on differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax basis using the liability method. Deferred tax liabilities are generally recognized for all taxable temporary differences, and deferred tax assets are generally recognized for all deductible temporary differences to the extent that it is probable that taxable profits will be available against which those deductible temporary differences can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable earnings will be available to allow all or part of the asset to be recovered.

Deferred tax assets and liabilities are computed using the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the balance sheet date. The effects of changes in the statutory rates are accounted for in the period that includes the enactment date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its current tax assets and liabilities on a net basis.

The Company follows the practice of recognizing the benefit from the amortization of acquired or generated tax losses in current earnings that are amortized.

- Current and deferred tax for the period – Current and deferred tax are recognized as an expense or income in periodic profit or loss, except when they relate to items that are recognized in other comprehensive income (loss) or directly in equity, in which case, the current and deferred tax are also recognized in other comprehensive income (loss) or directly in equity, respectively.

- Interests on recoverable tax balances – Interest on recoverable tax balances are presented in the consolidated statements of comprehensive income as interest income.

p. Foreign currencies – In preparing the financial statements of each individual group entity, transactions in currencies other than the entity’s functional currency (foreign currencies) are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are retranslated at the rates prevailing at that date. In the case of non-monetary items, which arise from the payment or collection of anticipated considerations, are recognized at the exchange rate in force of the date of the transaction.

Exchange differences are recognized in profit or loss in the period in which they arise except for:

- Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings;

- Exchange differences on transactions entered into in order to hedge certain foreign currency risks; and

- Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to profit or loss on sell all or part of the net investment.

q. Financial instruments – Financial assets and financial liabilities are recognized when a group entity becomes a part to the contractual provisions of the instrument.

Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.

r. Financial assets – Financial assets are classified into the following specified categories: “financial assets at fair value through profit or loss”, “held-to-maturity investments”, “available-for-sale financial assets” and “loans and receivables”. The classification depends on the nature and purpose of the financial assets and is determined at the time of initial recognition. All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the time frame established by regulation or convention in the marketplace.

The effective interest method is a method of calculating the amortized cost of a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, (where appropriate), a shorter period, to the net carrying amount on initial recognition.

The Company does not have financial assets classified as “available-for-sale financial assets”.

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and accounts receivable are measured at amortized cost using the effective interest method, less any impairment.

Financial assets are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected.

Objective evidence of impairment could include:

- Significant financial difficulty of the issuer or counterparty;

- Breach of contract, such as a default or delinquency in interest or principal payments;

- It becoming probable that the borrower will enter bankruptcy or financial re-organization; or

- The disappearance of an active market for that financial asset because of financial difficulties.

For certain categories of financial assets, such as trade receivables, assets that are assessed not to be impaired individually are, in addition, assessed for impairment on a collective basis. Objective evidence of impairment for a portfolio of receivables could include the Company’s past experience of collecting payments, as well as observable changes in national or local economic conditions that correlate with default on receivables.

For financial assets carried at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate.

The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in profit or loss.

Except for equity instruments available for sale, if, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through profit or loss to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed what the amortized cost would have been had the impairment not been recognized.

The Company recognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. If the Company neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Company recognizes its retained interest in the asset and an associated liability for amounts it may have to pay. If the Company retains substantially all the risks and rewards of ownership of a transferred financial asset, the Company continues to recognize the financial asset and also recognizes a collateralized borrowing for the proceeds received.

On recognition totally a financial asset, the difference between the asset’s carrying amount and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income and accumulated in equity is recognized in profit or loss.

s. Financial liabilities – Debt and equity instruments issued by a group entity are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument. Financial liabilities are classified as either financial liabilities “at fair value through profit or loss” or “other financial liabilities”.

Financial liability at fair value with changes through profit or loss is a financial liability classified as held for trading or it is designated as at fair value with changes through profit or loss.

A financial liability is classified as held for trading if:

- It has been acquired principally for the purpose of repurchasing it in the near term;

- On initial recognition, it is part of a portfolio of identified financial instruments that the Company manages together and has a recent actual pattern of short-term profit-taking; or

- It is a derivative that has not been designated as a hedging instrument and fulfils the condition to be effective.

- A financial liability other than a financial liability held for trading may be designated as at fair value through profit or loss upon initial recognition if:

o Such  designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise;

o The  financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Company’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or

o It  forms part of a contract containing one or more embedded derivatives, and IAS 39, Financial Instruments: Recognition and Measurement, permits the entire combined contract (asset or liability) to be designated as at fair value through profit or loss.

- Financial liabilities at fair value through profit or loss are recorded at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in profit or loss incorporates any interest paid on the financial liability and is included in the ‘other gains and losses' line item in the consolidated statement of comprehensive income.

- Other financial liabilities including borrowings are subsequently measured at amortized cost using the effective interest method. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or (where appropriate a shorter period), to the net carrying amount on initial recognition.

- The Company derecognizes financial liabilities when, and only when, the Company’s obligations are discharged, cancelled or they expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in profit or loss.

t. Derivative financial instruments – The Company sometimes uses derivative financial instruments for hedging risks associated with natural gas prices; this commodity is used for the production of goods, for which it conducted studies on historical consumption, future requirement and commitments acquired, thus diminishing its exposure to risks other than its normal operating risks.

These derivatives are initially recognized at fair value at the date the derivative contracts are entered into and subsequently are remeasured to the fair value at the end of reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

To mitigate the risks associated with changes in natural gas prices occurring naturally as a result of the supply and demand on international markets, the Company uses natural gas cash-flow exchange contracts or natural gas swaps to offset fluctuations in the price of natural gas, whereby the Company receives a floating price and pays a fixed price. Fluctuations in natural gas prices from volumes consumed are recognized as part of the Company’s operating cost.

At the inception of the hedge relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument is highly effective in offsetting exposure to changes in fair values or cash flows of the hedged item attributable to the hedged risk.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income and accumulated under the heading of fair value of derivative financial instruments, net of the corresponding income taxes. The gain or loss relating to the ineffective portion of hedge instrument is recognized immediately in profit or loss, and is included in the cost of sales line item.

The Company periodically evaluates the changes in cash flows of the derivative instrument to analyze if the swaps are highly effective for mitigating the exposure to natural gas price fluctuations. A hedge instrument is considered to be highly effective when changes in its fair value or cash flows of the primary position are compensated on a regular or cumulatively basis, by changes in fair value or cash flows of the hedging instrument in a range between 80% and 125%.

Amounts previously recognized in other comprehensive income are reclassified to profit or loss in the periods when the hedged item is recognized in profit or loss, in the same line of the consolidated statement of comprehensive income as the recognized hedged item. However, when the hedged forecasted transaction results in the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in equity are transferred from equity and included in the initial measurement of the cost of the non-financial asset or non-financial liability.

Hedge accounting is discontinued when the Company revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exerted, or when it no longer qualifies for hedge accounting. Any gain or loss accumulated from the hedge instrument that had been recognized in other comprehensive income and accumulated in equity at that time remains in equity until the forecast transaction is ultimately recognized in profit or loss. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

u. Revenue from contracts with customers – The income derived from contracts with customers is recognized at the moment in which the control of the goods or services is transferred to the client for an amount that reflects the consideration to which the company expect to have rights, in exchange for those goods and services.

Sale of goods:

Revenues from the sale of the products manufactured by the company ("products") are recognized at the time the asset control is transferred to the customer. The normal credit term on the sale of products is 30 to 90 days after delivery.

The Company considers that there are no other obligations to be fulfilled in the contracts, which are obligations to be fulfilled separately and in which a portion of the transaction price should be allocated. When determining the transaction price for the sale of products, the Company would consider the possible effects of the variable consideration, the existence of important financing components, the consideration other than cash and the consideration payable to the client.

Contract balances

Contractual assets

An asset of the contract is the right to obtain a consideration in exchange for the goods or services transferred to the client. If the Company fulfills an obligation when transferring goods or services to a customer before the customer pays the consideration or before the collection is due, an asset derived from the contract is recognized for the conditional consideration that the Company is entitled to collect.

Accounts receivable

An account receivable represents the company's right to collect a consideration that is unconditional, that is, only the passage of time is required so that the payment of the consideration is payable.

Contract liabilities and customer advances

A liability of the contract is the obligation to transfer control over goods or services to a customer, in the future, that arises from a collection right. If a customer pays the consideration before the Company transfers the goods or services, a contract liability is recognized when the payment is due and an advance from the client when the payment is made. Contract liabilities (or a customer's advance) are recognized as income when the Company fulfills its obligations under the contract.

v. Financial information by operating segment - An operating segment is an identifiable component of the Company that performs business activities, from which it may earn revenues and incur expenses, including those income and expenses related to transactions with other components of the entity and upon which the company has separate financial information that is evaluated regularly by the Board of Directors, in making decisions to allocate resources and assess segment performance.

w. Environmental liabilities - The Company and other steel companies are subject to stringent environmental laws and regulations. It is the policy of the Company to endeavor to comply with applicable environmental laws and regulations. The Company established a liability for an amount which the Company believes is appropriate, based on information currently available, to cover costs of environmental remediation it deems probable and estimable. The liability represents an estimate of the environmental remediation costs associated with the required future steps of remediation, based upon management's evaluation of probable outcomes. These estimates are based on currently available facts, existing technology and presently enacted laws and regulations. The precise timing of remediation activities cannot be reliably determined at this time due to the absence of any deadlines for remediation under the applicable environmental laws and regulations pursuant to which such remediation costs will be expended. Accordingly, the Company has not discounted its environmental liabilities. Currently no claims for recovery are netted against the recorded liabilities.

x. Cost of sales and expenses by function - The Company classifies its costs and expenses by function in the Consolidated Statements of Comprehensive Income, according to the industry practices where the Company operates.

Disclosure of Critical Accounting Judgments and Key Sources of Estimation [Abstract]

Critical accounting judgments and key sources of estimation

5) Critical accounting judgments and key sources of estimation

In the application of the Company’s accounting policies, which are described in Note 4, management is required to make judgments, estimates and assumptions regarding the carrying amounts of assets and liabilities. The estimates and associated assumptions are based on historical experience, the future and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis and the resulting changes are recorded on the period in which the estimate has been modified, if such change affects only that period or in future periods.

a. Critical accounting judgments – The following are the critical judgments in the application of accounting policies, apart from those involving estimations, that the management have made in the process of applying the Company’s accounting policies and that have the most significant effect on the amounts recognized in the financial statements:

- Functional currency – The Company’s management has evaluated all the indicators that in its opinion are relevant and has concluded that the Company’s functional currency is the Mexican Peso. Likewise, the Company has concluded that the functional currency of the companies located abroad are those mentioned in Note 4-a.

b. Key information for estimates – The following is the key assumptions, and other key sources of estimation at the consolidated balance sheet date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the following financial year.

- Allowance for doubtful accounts – Management applies judgment at each balance sheet date creating an allowance for doubtful accounts, in order to show the possible financial loss caused by the inability of customers to make the corresponding payments. The Company calculates its allowance based on the accounts receivable aging and other considerations for specific accounts.

- Net realizable value of inventory – At each balance sheet date, professional judgment is used to determine any impairment in inventory. Inventory is considered as impaired when its carrying value is higher than its net realization value.

- Impairment of long-lived assets in use – Management applies professional judgment at each balance sheet date to determine whether the long-lived assets in use are impaired. Long-lived assets in use are impaired when the carrying value is greater than the recoverable amount and there is objective evidence of impairment. The recoverable amount is the present value of the discounted future cash flows that will generate during the remaining useful life, or liquidation value (fair value).

- Estimating useful lives and residual values of property, plant and equipment – As described in Note 4 f, the Company reviews the estimated useful life and residual values of property, plant and equipment at the end of each annual reporting period.

- Impairment of goodwill – Determining whether goodwill is impaired requires an estimation of the value in use of the cash-generating units to which goodwill has been allocated. The value in use calculation requires management to estimate the future cash flows expected to arise from the cash-generating unit and a suitable discount rate in order to calculate present value.

- Employee Benefits - The valuation of employee benefits is carried out by independent actuaries based on actuarial studies. Among others, the following assumptions, which can have an effect are used:(i) discount rates, (ii) the expected growth rates of wages and (iii) turnover rates and mortality recognized tables.

A change in the economic, employment and fiscal conditions could modify the estimates.

- Contingencies – The Company is subject to transactions or contingent events for which it uses professional judgment in the development of estimates of probability of occurrence. Factors that are considered in these estimates are the current legal situation at the date of the estimate and, the opinion of the legal advisers.

- Deferred income tax assets – The Company reviews the carrying amounts at the end of each reporting period and reduces deferred income tax assets to the extent that it is not probable that sufficient taxable profit will be available to allow all or part of the deferred income tax assets to be utilized. However, there is no assurance that the Company will generate sufficient taxable profit to allow all or part of its deferred income tax assets to be realized.

- Valuation of financial instruments –The Company has certain types of derivative financial instruments (gas swaps), and the valuation techniques that includes to determine the fair value are based in data obtained in observable markets.

The Company’s management believes that the chosen valuation techniques and assumptions used are appropriate in determining the fair value of derivative financial instruments. At December 31, 2018 and 2017 the Company has not derivative financial instruments.

Trade and other receivables [abstract]

Trade receivables - Net

7) Trade receivables – Net

The average collection period on sales of goods is between 30 and 60 days. No interest is charged on the outstanding accounts receivables from clients. The Company has recognized an allowance for doubtful accounts to show the possible financial loss caused by the inability of customers to make the corresponding payments. Allowances for doubtful accounts are calculated based on several factors including price adjustments, likelihood of recovery, aging and historical experience.

Credit limits and scoring by customer are reviewed twice a year. On December 31, 2018 and 2017 there are no customers who represent more than 5% of the total balance of trade receivables. The Company does not hold any collateral or other credit enhancements over these balances nor does it have a legal right of offset against any amounts owed by the Company to the counterparty.

Trade receivables disclosed below include amounts that are past due at the end of the reporting period for which the Company has not recognized an allowance for doubtful debts because there has not been a significant change in credit quality and the amounts are still considered recoverable. The Company does not hold any collateral. In general terms, the accounts receivable does not show impairment.

Age of receivables that are past due but not impaired is as follows:

	At December 31,
	2 0 1 8		2 0 1 7
30 - 60 days	$	221,996	$	72,778
61 - 90 days		57,119		57,629
91 + days		188,262		162,807
Total	$	467,377	$	293,214

During the years ended December 31, 2018 and 2017, the movement in the allowance for doubtful accounts was as follows:

	2 0 1 8		2 0 1 7
Balance at beginning of year	$	199,855	$	59,095
Provisions		7,486		141,140
Translations effects		24,437		(380)
Balance at end of year	$	231,778	$	199,855

In determining the nonrecoverable portion of accounts receivable, the Company considers any change in the credit quality of the trade receivable from the date credit was initially granted up to the end of the reporting period. The concentration of credit risk is minimum, due to the fact that the customer base is large and unrelated.

Republic made an agreement with a third party ("buyer") to carry out a factoring of accounts receivable to customers. The maximum established amount of advances related to the allocation of accounts is USD $ 30 million. The remaining amount between the received and the value of the invoices is kept in reserve by the "buyer". The payments of the funds retained in reserve minus a discount will be made by the buyer within 4 days after receiving the collection payments related to each assigned account. Said discount will be made on the total of the invoice and is in a range of 1% if the payment is made within 15 days (from the advance date) or up to 3.75% if paid within 90 days days and 1% for every additional fifteen days until the account is settled. This discount is recognized as an interest expense in the consolidated statement of comprehensive income.

The purchaser has no recourse against the Company if payments are not received due to insolvency of an account debtor within 120 days of the invoice date. However, while the facility calls for the sale, assignment, transfer and conveyance of all rights, title and interests in the selected accounts receivable, the purchaser may put and charge-back any receivable not paid to the purchaser within 90 days of purchase for any reason besides insolvency of the account debtor. As collateral for the repayment of advances for receivables sold, the purchaser has a priority security interest in all accounts receivable of the Company (as defined by the Uniform Commercial Code of the United States of America).

In 2018, the Company sold a nominal amount of USD $ 23.1 million ($25.4 million in 2017) of accounts receivable. The discount fees incurred by this contract were approximately USD $ 0.5 million in 2018 and USD$ 0.5 in 2017. These fees were included in expenses for interest in the Comprehensive Income Statement. As of December 31, 2018, and 2017 the buyer has USD$ 2.7 million and USD$ 1.9 million, respectively, of receivables that have not been recovered by the buyer. The amount uncollected for 2018 are subject to a possible return of the Company by the buyer. These accounts receivable is included in the total trade receivables for the purpose of assessing the recoverability of them and, where appropriate, determine the adequacy of allowance for doubtful accounts.

The Company has $ 952,786 and $ 1,037,470 of coke inventory on hand as of December 31, 2018 and 2017 respectively (See note 4-e), which the Company would use as an input to its blast furnace in the Lorain facility which is currently idled. Management of the Company continually evaluates both the idled facility and the coke inventory for impairment. Management periodically evaluates the potential degradation of the coke inventory and has determined that it continues to be suitable as a blast furnace input or, alternatively, for sale to other blast furnace facilities. As of April 2019, Management expects that there will be recovery in the industries in which the Company operates; this would result in the blast furnace being restarted in the future. However, the Company has recorded an impairment to the blast furnace resulting in a book value of zero. The Company has continued incurring certain costs to maintain the assets in Lorain, including the blast furnace and the coke; such costs are expensed as incurred. In order to restart the blast furnace, the Company will incur certain expenses for the restoration of the equipment, and there is still uncertainty on the date on which the blast furnace will restart its operation. The Company cannot offer any guarantee of the restarting of the total operation of the blast furnace or when conditions will become economically feasible.

As of December 31, 2014, Republic had invested USD$158.8 million in an electric arc furnace and associated equipment at its steelmaking facility in Lorain, Ohio, USA, to meet growing customer demand for the Company's SBQ (special bar quality) steel. The location was chosen for its strategic proximity to customers and its skilled workforce. The construction of the Lorain electric arc furnace began mid-year 2012 and the Company began steelmaking operations in July 2014. The amounts above include USD $ 45.4 million capitalized from labor and manufacturing overhead related to the construction of the furnace and is presented as a component of machinery and equipment.

In June 2015, Republic Steel temporarily suspended operations in the newly constructed electric arc furnace at the Lorain facility in response to the severe economic downturn in the exploration for oil and gas sector, following the sharp drop in the price of oil which has led to significant market declines and demand for steel product, for those markets. As a consequence of this event, management determined a triggering event took place to where the long-lived assets at the Lorain facility may not be fully recoverable. Management performed an analysis of the fair value of the Lorain facility with the assistance of an independent valuation firm and determined that net book value exceeded the fair value by approximately USD$130.7 million and as such recognized an asset impairment of this amount during the year ended December 31, 2015. The fair value determination at the Lorain facility was based on an independent valuation of the assets using the comparable match method of the market approach to determine fair value. The income approach was not considered an appropriate fair value measurement due to the absence of reliable forecast data on the future behavior of oil market.

Subsequent to December 31, 2015, the entire Lorain facility was temporarily idled effective March 31, 2016 and management has no near-term plans to restart the facility, and the expectation is that it will be restarted when oil and gas market conditions improve substantially, particularly in the oil and gas drilling industry. The Company has property, machinery, and equipment with a net book value of approximately USD$ 32.7 and USD$ 32.2 million as of December 31, 2018 and 2017, pertaining to the Lorain, Ohio facility after recording the impairment charge of USD$ 130.7 million as mentioned above. The impairment charge did not impact the operations or future cash flows of the Company, as it was a provision and not a cash expenditures. Management further assessed if there were any impairments at the Company's other cash generating units and determined that as of December 31, 2016 no other cash generating units were impaired based on current projections.

Such benefits consist of a one-time payment equivalent to 12 days wages for each year of service (at the employee’s most recent salary, but not to exceed twice the legal minimum wage), payable to all employees with 15 or more years of service, as well as to certain employees terminated involuntarily prior to the vesting of their seniority premium benefit. These obligations are calculated by independent actuaries using the projected unit credit method.

Such benefits consist of a one-time payment of three months’ wages plus 20 days’ wages for each year of service, payable upon involuntary termination without just cause. Severance benefits payments are recorded directly in the consolidated statement of comprehensive income (loss) at the time they are paid, unless they are related to restructuring expenses, which are recorded when there is a present obligation from past events.

d. Employee profit sharing (EPS) – The Mexican Constitution and the Labor Law grant employees the right to receive a 10% share of the employers’ profits. Employees Profit Sharing is computed in similar terms to the taxable profit for income tax, excluding mainly the employee’s profit sharing paid this year and the amortization of tax losses and decreasing the non-deductible part of the social security for purposes of income tax. For the years 2018 and 2017, EPS amounted to $ 67 and $ 0, respectively. EPS is recorded in the results of operations for the year in which it is incurred.

e. Governmental defined contribution plan – Under Mexican legislation, the Company must make payments equivalent to 2% of its workers’ daily integrated salary (ceiling) to a defined contribution plan that is part of the retirement savings system. The expense in 2018, 2017 and 2016 was $13,687, $12,838 and $11,323, respectively.

Foreign entities (Republic)

Republic is the only subsidiary of the Company which offers other benefits and pension plans to their employees. Such benefit plans to employees are described below:

a. Collective Bargaining Agreements

As of December 31, 2018, 81% of the Republic employees are covered by a collective bargaining agreement (labor agreement) with the United Steelworkers (“USW”). The agreement initially expired on August 15, 2016 and was extended for a further three years through August 15, 2019. The extended agreement renews all the provisions, understandings and agreements set forth in the January 1, 2012 Basic Labor Agreement. The base rates of pay were determined under the extended agreement and will remain unchanged from those ruling under the expired agreement as of August 16, 2016. The extended agreement provides the Company’s quarterly contributions to fund the Republic Retirement VEBA and Benefit Trust (the “Benefit Trust”) to be reduced from $2.6 million to $0.25 million beginning in August 15, 2016 through June 30, 2019. Effective July 1, 2019, the Company’s contribution to the Benefit Trust will change to $4.00 per hour for each hour worked by USW represented employees.

b. Defined Contribution Plans

Plan for employees- Republic participates in the Steelworkers Pension Trust (SPT), a defined benefit multi-employer pension plan. The Company obligations to the plan are based upon fixed contribution requirements. Republic contributes a fixed amount of USD$1.68 per hour for each covered employee's contributory hours, as defined under the plan.

Participation in a multi-employer pension plan agreed under terms of a collective bargaining agreement differs from a traditional qualified single employer defined benefit pension plan. The SPT shares risks associated with the plan in the following respects:

I. Contributions to the SPT by Republic may be used to provide benefits to employees of other participating employers;

II. If a participating employer stops contributing to the SPT, the unfunded obligations of the plan may be borne by the remaining participating employers; and

III. If Republic chooses to stop participating in the SPT, Republic may be obliged to pay an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

c. VEBA Benefit Trust

The Company is required to make quarterly contributions to the defined contribution plan for post-retirement health benefits VEBA as determined by the terms of the USW collective bargaining agreement. The Benefit Trust is a health and welfare plan for USW retiree benefits, and is not a "qualified" plan under the regulations of the Employee Retirement Income Security Act of 1974. For the years ended December 31, 2018, 2017 and 2016, the Company recorded expenses of USD$ 1.0 million, USD$ 6.9 million and USD$ 10.4 million, respectively, related to this benefits plan.

For the years ended December 31, 2018, 2017 and 2016, Republic recorded combined expenses of USD$ 3.6 million, USD$ 3.5 and USD$ 10.0 million, respectively, related to the funding obligations of the retirement healthcare and pension benefits. The cost contributions to these two funds have been reduced from USD $ 2.6 million to USD$ 0.25 million per quarter effective after the review of the collective agreement on August 16 2016.

d. 401(k) Plans

The Company has a 401(k) defined contribution retirement plan that covers almost all the salaried and nonunion hourly employees. This plan is designed to provide retirement benefits through Company contributions and voluntary deferrals of employees' compensation. The Company funds contributions to this plan each pay period, based on the participant's age and years of service as of January first of each year. The amount of the Company contribution is equal to the monthly base salary multiplied by the appropriate percentage based on age and years of service. The contribution becomes 100% vested upon completion of three years of vesting service. In addition, employees are permitted to make contributions to this 401(k)-retirement plan through payroll deferrals. In this case, the Company provides a 25.0% matching contribution for the first 5.0% of payroll that an employee elects to contribute. Employees are 100% vested in both their and Republic matching 401(k) contributions. For the years ended December 31, 2018, 2017 and 2016, the Company recorded expense of USD$ 1.0 million, USD$ 0.8 million and USD$ 0.7 million, respectively, related to this defined contribution retirement plan.

Employees who are covered by the USW labor agreement are eligible to participate in the 401(k) defined contribution retirement plan through voluntary deferrals of employees' compensation. There are no Company contributions or employer matching contributions relating to these employees.

e. Profit Sharing and Incentive Compensation Plans

The labor agreement includes a profit sharing plan to which the Company is required to contribute The extended agreement modified the plan to the following quarterly pretax income, as defined in the labor agreement ("EBT"): 3% of EBT between $0 and $25 million per quarter; 4% of EBT between $25 and $75 million per quarter; and 5% of EBT over $75 million per quarter. USD $ 1.0 million of expense was recorded for the year ended December 31, 2018, 2017 and 2016, because the current and prior year thresholds had not been achieved.

Republic has a profit-sharing plan for all salaried employees and nonunion workers. The profit-sharing plan was based on achieving certain EBITDA, inventory and shipments targets. In the year ended December 31, 2018, 2017 and 2016, the Company paid USD 0.8 million, USD $ 0.9 and USD $0.6 million respectively under this plan.

Financial Instruments

21) Financial instruments

a. Capital risk management – The Company manages its capital to ensure that its subsidiaries will be able to continue as a going concern while maximizing the return to its stockholders through the reinvestment of its earnings. The Company’s policy is to not obtain bank loans or any other financing transaction.

b. Market risk – Market risk is the risk that the fair value of future cash flows of a financial instrument fluctuates due to changes in market. Market prices include the exchange risk, interest rate risk and the raw material prices risk.

c. Foreign exchange risk management – The Company undertakes certain transactions denominated in foreign currencies, hence, exposures to exchange rate fluctuations arise. The exposures in exchange rate are managed within the settings of the approved policies. The book value of the monetary assets and monetary liabilities denominated in foreign currency at the end of the reporting period are as follows (includes foreign subsidiaries):

	Currency: Mexican peso
	December 31,
	2 0 1 8		2 0 1 7

Equivalent in U.S. Dollars (thousands)	USD$	309,414	USD$	327,592

d. Credit risk management – Credit risk refers to the risk that a counterpart will default on its contractual obligations resulting in financial loss for the Company. The Company has adopted a policy of only dealing with creditworthy counterparties. The Company only transacts with entities that have a risk grade equivalent to the investment grade and higher. The Company investigates and rates its major customers. The Company exposure and the credit ratings of its counterparties are continuously monitored and the accumulated value of transactions concluded is spread amongst approved counterparties. Credit exposure is controlled by counterparty limits that are reviewed and approved annually by the risk management committee.

Trade receivables consist of a large number of customers dedicated to construction and automotive industries, distributed in different geographic areas. Ongoing credit evaluation is performed on the financial condition of accounts receivable.

The Company does not have significant credit risk exposure with any single counterparty or any group of counterparties having similar characteristics. The Company defines that the counterparties that have similar characteristics are considered related parties. Concentration of credit risk to any other counterparty did not exceed 5% of gross monetary assets at any time during the year.

The credit risk on liquid funds and derivative financial instruments is limited because the counterparties are banks with high credit-ratings assigned by international credit-rating agencies.

e. Liquidity risk and risk tables – Ultimate responsibility for liquidity risk management rests in the board of directors, which has established an appropriate liquidity risk management framework for the management of the Company’s short, medium and long-term funding and liquidity management requirements. The Group manages liquidity risk by maintaining adequate reserves, banking and credit facilities, by continuously monitoring forecast and actual cash flows, and by matching the maturity profiles of financial assets and liabilities. The following table sets out details of additional bank lines of credit (to be used as letter of credits) that the Company has at its disposal to reduce liquidity risk. These lines of credit are obtained by the Company and one part of them has been used for some of the subsidiaries of Industrias CH, S.A.B. de C.V.:

Disclosure of Contingencies [Abstract]

Contingencies

23) Contingencies

As of December 31, 2018, the Company has the following contingencies:

a. Pacific Steel, Inc. (PS), a subsidiary located in National City in San Diego County, California, United States of America, for which main activity is the purchase and sale of scrap, has the following environmental contingencies:

California Department of Toxic Substances Control

On September 2002, the Department of Toxic Substances Control (DTSC) inspected PS facilities based on an alleged complaint from neighbors due to PS’s excavating to recover scrap metal on its property and on a neighboring property, which PS rents from a third party (BNSF Railway). In this same month, DTSC issued an enforcement order of imminent and substantial endangerment determination, which alleges that certain soil piles, soil management and metal recovery operations may cause an imminent and substantial danger to human health and the environment; consequently, DTSC sanctioned PS for violating Hazardous Waste Control Laws in the State of California and imposed the obligation to remedy the site. On July 26, 2004, in an effort to continue with this order, DTSC filed against PS a Complaint for Civil Penalties and Injunctive Relief in San Diego Superior Court. On July 26, 2004, the court issued a judgment, whereby PS was obligated to pay USD$ 0.2 million, which has been paid.

On June 6, 2010, the DTSC and the San Diego Department of Environmental Health (DEH) inspected the facilities of PS, in response to a general complaint. On August 10, 2010 DTSC and DEH conducted a second inspection and found seven infractions. The DEH is satisfied with the compliance of PS on those issues; however, on October 19, 2010 the technical division of the DTSC recommended to the legal division of DTSC that it impose significant penalties.

The land remediation was suspended at the beginning of 2011 due to the inefficiency of the process, which was verified by several studies. As an alternative, once the necessary permits were obtained from the authorities in Mexico, the Mexicali plant began the process of importing non-RCRA soil for final disposal in a secure landfill based in Nuevo Leon State. This landfill is deposited after the separation of the metal content, which is used as raw material in the smelting process. PS has completed the shipment of non-RCRA soil for final disposal in Nuevo Leon State at this time.

The disposition of a stack estimated at 8,000 tons of material classified RCRA (hazardous for Federal purposes) was also considered for shipment to Mexico. The process began in early 2013, but the response from the authorities was slow. Therefore, on April 9, 2015, a letter from the California Attorney General Department of Justice (Attorney General) was received where PS is required to, in the absence of obtaining permission from the Mexican authorities; present a program for transport the pile of contaminated soil classified as RCRA to an authorized confinement in the United States at the latest on April 22, 2015. This letter warned that PS must ship the RCRA soil no later than July 9, 2015, or risk DTSC proceeding with a civil lawsuit seeking the maximum amount of fines established by law and corresponding legal redress.

On April 21, 2015, PS sent a letter to the Attorney General explaining that the authorities in Mexico had not denied permission to the Company but had simply requested that it present its application in a different format, which had already been presented and reviewed by the authority on April 17, 2015.

On July 23, 2015, the Attorney General denied the extension requested by PS and demanded the immediate shipments of the RCRA stack to an authorized landfill. PS began transporting RCRA soil on July, 29, 2015, and completed removal of the RCRA stack by September 12, 2015 with a total of 3,000 metric tons.

On January 5, 2016, the Attorney General and PS stipulated to filing a "final judgment and order on consent" or Consent Judgment in San Diego Superior Court. The parties negotiated the Consent Judgment, which includes the following terms:

- PS to pay USD$ 0.138 million as a civil penalty for alleged violations of the 2004 Corrective Action Consent Agreement. PS has made all of the required payments to DTSC as of December 31, 2017.

- Remove the RCRA soil pile and send it to an approved landfill. The Judgment indicates that the Company complied with this commitment by October 2, 2015.

- After removing the RCRA soil pile, the Company must take samples of the soil in the area where the RCRA soil pile was located. Samples were taken and the results indicated that the soil had pollution levels that exceed the limits set by the State. On April 7, 2016, the Attorney General and DTSC demanded that the Company remove soil 10 feet across and 2 feet deep on the perimeter of the area where the RCRA soil pile was located and dispose of it in an approved confinement. Instead, PS convinced DTSC to enter into a Tolling Agreement on August 10, 2016, which tolls for two years (until August 10, 2018) the statute of limitations for DTSC to challenge PS’s compliance with the Consent Judgment. This Tolling Agreement was extended on August 10, 2018, for an additional two-year period. This Tolling Agreement remains in force as of December 31, 2018, and will end as of August 10, 2020.

- The Company shall continue to meet the conditions of the final judgment, the corrective measures, and all tasks arising from this, which were entered in the same court in 2004.

PS is working to develop a “corrective measures study” (CMS) that is intended to develop a plan for determining what remedy will be implemented at the site. As of December 31, 2018, it is unclear what will be the appropriate remedy to implement at the PS site, when the CMS will be completed, how long remediation will take, and how much it will cost.

b. As with most steel producers in United States of America, Republic could incur significant costs related to environmental issues in the future, including those arising from environmental compliance activities and remediation stemming from historical waste management practices at the Republic’s facilities. The reserve created to cover probable environmental liabilities of USD$ 2.6 million and USD$ 2.7 million were recorded as of December 31, 2018 and 2017, respectively. The reserve includes incremental direct costs of remediation efforts and post-remediation monitoring costs that are expected to be paid after corrective actions are complete. As of December 31, 2018, the current and non-current portions of the reserve amounted to USD$ 1.0 million and USD$ 1.6 million, (USD$ 1.0 million and USD$ 1.7 million in 2017), respectively, are included in accounts payable and accumulated liabilities in the short and long term, respectively, in the Consolidated Statements of Financial Position.

c. The Company is not aware of any material environmental remediation liabilities or contingent liabilities relating to environmental matters with respect to facilities, for which the establishment of an additional reserve would be necessary at this time. In the event that, in the future, the Company incurs in any such additional expenses, these costs will most likely be incurred over a number of years. However, future regulatory action regarding historical waste management practice in the facilities of Republic PS and future changes in applicable laws and regulations may require the Company to incur significant costs that may have a material adverse effect on the future financial performance of the Company.

d. The Company is involved in a series of lawsuits and legal claims that have arisen during the normal course of its operations. The Company and its legal advisors do not expect the outcome of these matters to have any significant adverse effect on the Company's financial position and results of operations, therefore it has not been recognized any liabilities for such lawsuits and claims.

e. Mexican tax authorities have the right to review, at least the previous five years and could determine differences in taxes payable, plus any corresponding adjustments, surcharges and fines.

f. Tax authorities in United States of America have the right to review, at least the previous three years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines.

g. Canadian tax authorities have the right to review, at least the previous four years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines.

h. Brazilian tax authorities have the right to review, at least the previous five years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines.

i. On January 19, 2017, the Company was notified with the excerpt issued by the General Direction of Crimes and Sanctions of the National Banking and Exchange Commission (CNBV), for the probable realization, in the re-purchase of own stock operations, of several behaviors that, under the judgment of the CNBV, could be different to the ones established in the “Ley del Mercado de Valores (LMV)”. On February 9, 2017 Grupo Simec filed the statement of manifestations to the administrative sanction procedure. The resolution was favorable for the company, issued on May 15, 2018.

On September 5, 2017, Grupo Simec and GV do Brasil were notified of the arbitration procedure filed by SMS Concast at the International Court of Arbitration (ICC), which claims the payment of USD $ 1.4 million plus expenses, for the concept of additional costs, incurred in the construction and assembly of the steelmaking area of the Brazilian plant. On November 6, 2017, the companies of the Group replied to the demand and filed a counterclaim against SMS Concast for the amount of USD $ 5 million, which GV do Brasil utilized on the equipment to work properly. The panel of arbitrators is already constituted and the resolution of the matter is in process.

j. In February 2017, the Securities and Exchange Commission ("SEC") notified the Company of the opening of an investigation to determine if the Company's management committed infractions of US federal securities laws related to the failure to maintain internal control over financial reporting. This investigation is derived, in part, from the failures in these systems which were reported in the 20-F (Annual Report) for the fiscal year 2015. On February 21, 2016, the Company began implementing the corrective measures recommended by a specialist firm in order to better comply with the COSO framework. On January 29, 2019, the Company reached a settlement with the SEC. Under the terms of the settlement, the Company paid a civil penalty of USD $200,000 and retained an independent consultant to ensure remediation of material weaknesses and the implementation and maintenance of internal controls over financial reporting. The Company’s remediation efforts continue.

k. During the year 2018 Grupo Simec and some of its subsidiaries have been audited by the tax authorities of Mexico with respect to fiscal years from 2013 to 2017. The tax which the authority pretends to impose are non-existent taxes, which we have been litigating through various means including “amparo”, lawsuits, resources of revocation in some cases and nullity lawsuit in others. As of December 31, 2018 the payment has not been enforceable in any of the disputed matters. The amount of tax credits being appealed in court ascends to $ 5,880 million.

Disclosure of Retrospective Restatement of Financial Statements [Abstract]

Retrospective restatement of the 2016 and 2017 financial statements

24)  Retrospective restatement of the 2016 and 2017 financial statements.

During 2018, the Company identified certain misstatements in the financial statements as of and for the years ended December 31, 2017 and 2016. The Company has restated the balances and results for these periods as presented in the report in accordance with the guidance of IAS 8 – Accounting Policies, Changes in Accounting Estimates and Errors.

These involuntary errors were specifically that significant information related to transactions was not available to the accounting staff in regards to some non-routine transactions. This lack of timely, accurate information lead to incorrect accounting treatments and misstatements to the financial statements.

These errors relate to the recording of advances made to related parties and the accrual of related interest income.

For this reason, the accrued interest and the related income tax effect of certain loans granted to related parties were not previously recognized in the Company’s financial statements. The interest to be recognized through the restatement is as follows:

There were additional errors identified in the presentation of accounts and loans receivable with related parties in the 2016 and 2017 financial statements. These errors relate to the classification of certain balances as short-term assets which are long-term assets. There were additional corrections related to the reclassification of certain accounts payable to loans payable.

Commitments

25) Commitments

a. On May 1, 2018, the Company signed a contract with ArcelorMittal S.A. in Brazil, for the acquisition of Cariacica and Itauna steels for rent, producing plants and wire drawing equipment for the production of wires and derivatives.

The Cariacica unit has the capacity to produce 600 thousand metric tons of liquid steel per year and 450 thousand metric tons of rolled steel products. This plant has more than 500 employees and can produce rod and light structural profiles. The factory is located in the city of Cariacica, next to the city of Victoria, in the state of Espírito Santo on a land of more than 1,200,000 m2.

The Itauna unit has an installed capacity to produce 120,000 metric tons per year of steel laminate products and can manufacture light structural profiles and rods. The plant is located in the city of Itauna in the state of Minas Gerais, less than 100 kilometers away from Belo Horizonte and has 94 employees. The factory is leased under a contract expiring in August 2020.

b. Republic leases certain equipment, office space and computer equipment under non-cancelable operating leases. The leases expire at various dates through 2020. During the years ended December 31, 2018, 2017 and 2016, rental expenses relating to operating leases amounted to USD$ 0.7 million, USD$ 0.5 million, and USD$ 1.1 million, respectively. Currently there are no additional obligations post-2020.

c. In January 2013, the Company entered into an agreement with EnerNOC which enables Republic to receive payments for reducing the electricity consumption during a dispatch declared by PJM Interconnection as an emergency. The agreement is for 5 years, effective January 31, 2013 and expires on May 31, 2018. During the years ended December 31, 2018, 2017 and 2016, the Company recognized income from this agreement of USD$ 2.8 million, USD$ 1.0 million and USD$ 1.0 million, respectively. Unlike the previous contract the payments are earned by event and how they accrue.

d. In January 2013, the Company signed a product supply agreement for 15 years with Air Products and Chemicals, Inc. The agreement required that Air Products and Chemicals build and install a plant for the production of oxygen, nitrogen, and argon in the facilities of Lorain, Ohio. The term of 15 years of this agreement would come into force at the time the plant becomes operational. The plant did not start operations as indicated in Note 10. In August 2016, the Company signed a new agreement with Air Products and Chemicals, Inc., to acquire the previously installed plant, for an amount of USD $ 30 million and cancel in its entirety the supply contract. The amount of the purchase was agreed to settle it in the following way: an initial payment of USD $ 1.2 million and the remaining of USD $ 28.8 million over a period of 6 years with monthly payments equal to USD $ 0.4 million, without any interest payment.

e. In connection with a sales and use tax audit by the Ohio Department of Taxes covering the period from January 1, 2009 to December 31, 2012, an assessment of $ 2,452,028 (including interests of $ 394,138) against the Company was issued, on December 9, 2016. The Company does not agree with the evaluation in its entirety and has filed a Reevaluation Petition on January 30, 2017 appealing the assessment to the Ohio Board of Tax Appeals. As of July 30, 2019, no resolution has been obtained on this appeal.

Due to the nature of this matter and the uncertainty of the resolution on the appeal that is in the early stages, the Company has not recorded an expense in the fiscal year 2018 or 2017 that recognizes the evaluation or any estimated amount of liquidation.

f. In January 2018, the Company entered into a contract with the supplier ECOM, LTDA. for an amount of USD $ 6.1 million for the purchase of energy of 10,000 MWH per month, for its subsidiary GV do Brasil Industria y Comercio de Aço LTDA. All monthly payments with monthly due date 6 days after the closing date of the month. The contract ends in February 2019.

g. In January 2018, the Company entered into a contract with the supplier ECOM, LTDA. for an amount of USD $ 6.3 million for the purchase of energy of 10,000 MWH per month, for its subsidiary GV do Brasil Industria y Comercio de Aço LTDA, starting the supply in 2019. All payments with monthly maturity 6 days after of the month end closing. The contract ends in February 2020.

h. In December 2017, the Company entered into a contract with the supplier COMERC, LTDA. for an amount of USD $ 5.2 million for the purchase of 8,000 MWH of energy per month, for its subsidiary GV do Brasil Industria y Comercio de Aço LTDA. All payments with monthly due date 6 days after of the month end closing. The contract ends in February 2019.

i. On February 22, 2018, a contract was signed with Primental Technologies of Italy, the United States of America and Mexico for the construction of the rolling mill and the supply of a new reheating furnace for the Mexicali plant, which will increase capacity of finished product manufacturing from 17,500 to 22,500 tons per month. An advance payment of 20% has already been paid for USD $ 1.67 million and the placement of the letters of credit is in process. The term of execution of the project is 16 months and a budget of $ 23.2 million dollars is estimated.

Basis of preparation and presentation of the financial statements (Policies)

12 Months Ended

Dec. 31, 2018

Disclosure of basis of preparation and presentation of the financial statements [Abstract]

Conversion of foreign subsidiaries' financial statements

a. Conversion of foreign subsidiaries financial statements – The functional and reporting currency of the Company is the Mexican peso ($). The financial statements of foreign subsidiaries were translated to Mexican pesos in accordance with International Accounting Standard (IAS) 21, The Effects of Changes in Foreign Exchange Rates. Under this standard, the first step to convert financial information from operations abroad is the determination of the functional currency. The functional currency is the currency of the primary economic environment of the foreign operation or, if different, the currency that mainly impacts its cash flows.

The U.S. dollar (US Dollar or USD$) was considered as the functional currency of all the U.S. subsidiaries and Brazilian Real for subsidiaries established in Brazil; therefore, the financial statements of these subsidiaries abroad were converted to Mexican pesos applying:

- The exchange rates at the balance sheet date, to all assets and liabilities.

- The historical exchange rate at stockholders’ equity accounts and revenues, costs and expenses.

The conversion differences are carried directly to the consolidated statements of comprehensive income as other comprehensive income under the caption translation effects of foreign subsidiaries.

Relevant exchange rates used in the preparation of the consolidated financial statements of foreign subsidiaries were as follows (Mexican pesos per one U.S. dollar):

Current exchange rate as of December 31, 2018	19.66
Current exchange rate as of December 31, 2017	19.74
Average exchange rate for the year ended December 31, 2018 (*)	19.23
Average exchange rate for the year ended December 31, 2017 (*)	18.94
Current exchange rate as of April, 9 of 2019	18.97

(*) Average exchange rate used to translate revenues, costs and expenses of the companies mentioned above.

Business combinations

b. Business combinations – Acquisitions of subsidiaries and businesses units are accounted for using the acquisition method. The consideration for each acquisition is valued at its fair value on the date of exchange of the transferred assets, liabilities incurred or assumed and capital instruments issued by the Company in exchange for control of the acquired. The costs related to the acquisition are recognized in the results when incurred.

At the date of acquisition, the identifiable assets acquired and the liabilities assumed are recognized at their fair value, except:

- Deferred tax assets or liabilities and liabilities or assets related to employee benefit arrangements, which are recognized and measured in accordance with IAS 12, Income Taxes, and IAS 19, Employee Benefits, respectively.

- Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5, Non-current Assets Held for Sale and Discontinued Operations, are measured in accordance with that Standard.

Any excess of the cost of acquisition for the Group's interest in the net fair value of the identifiable assets, liabilities and contingent liabilities of the associated company recognized at the date of acquisition is recognized as goodwill. Goodwill is included in the carrying amount of the investment and is assessed for impairment annually. Any excess of the Group's interest in the net fair value of the assets, liabilities and contingent liabilities over the cost of acquisition, after the reassessment, is immediately recognized in profit and loss.

When the consideration transferred by the Company in a business combination includes assets or liabilities resulting from a contingent consideration arrangement, the contingent consideration is measured at its acquisition-date fair value and later adjustments to the consideration are recognized against goodwill, providing that it has arisen from reliable information on the fair value at the acquisition date and occur during the ‘measurement period’ (which cannot exceed one year from the acquisition date). All other subsequent adjustments are recognized in profit or loss.

The subsequent accounting for changes in the fair value of the contingent estimates that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates. Contingencies classified as assets or liabilities are remeasured at subsequent reporting dates in accordance with IAS 37, Provisions, Contingent Liabilities and Contingent Assets, as appropriate, with the corresponding gain or loss being recognized in profit or loss.

When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree are remeasured to fair value at the acquisition date (i.e. the date when the Company obtains control) and the resulting gain or loss, if any, is recognized in profit or loss. Amounts arising from interests in the acquiree prior to the acquisition date that have been previously recognized in other comprehensive income (loss) are reclassified to profit or loss where such treatment would be appropriate if that interest were disposed of.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date.

Cash and cash equivalents and temporary investments

c. Cash and cash equivalents and temporary investments – Cash consists of deposits in bank accounts that do not generate interest. Cash equivalents consists in temporary investments referred to as short-term fixed income investments whose original maturity is less than three months. These investments are reported at cost plus accumulated interest. The value so determined approximates their fair value.

Temporary investments in equity instruments are measured at the fair value prevailing at the date of the financial statements. Subsequent changes in the fair value are recognized in profit or loss.

Allowances for doubtful accounts

d. Allowances for doubtful accounts – The Company follows the practice of recording an estimation of an allowance for doubtful accounts, which is determined by considering the balances of clients with more than a year old, those in litigation and or specific recovery problems. Actual results may differ materially from these estimates in the future.

Inventories and cost of sales

e. Inventories and cost of sales – Inventories are stated at the lower of cost or net realizable value. The cost allocation formula used is the average cost. The cost includes acquisition costs of materials, labor and overhead costs related to manufacturing and distribution, based on normal activity levels. The net realizable value represents the estimated selling price for inventories less all estimated costs of completion and other necessary to make the sale, which is recorded in the statement of financial position and against account is the cost of sales.

The Company classifies raw material inventory in the Consolidated Statements of Financial Position based on its expected consumption period, presenting as long-term inventories those which in accordance with historical data and production trends will not be consumed in the short-term (one year).

The Company classified as long-term inventory certain parts and rollers that, according to historical data and trends, showing that such inventories will not be consumed in the short-term. The Company utilizes coke, a form of coal, as a raw material input to fuel its blast furnace which has been inactive in Lorain, Ohio USA plant (see Note 9). The Company has 136,541 metric tons (MT) of coke inventory valued at 953 million Mexican pesos (average of USD$ 355/MT) on hand at December 31, 2018 and 136,541 MT of coke inventory valued at 1,037 million Mexican pesos (average of USD$ 385.00/MT) on hand at December 31, 2017 that is classified as long-term in the accompanying Consolidated Statements of Financial Position.

The Company follows the practice of providing a reserve for slow-moving inventory, considering the total of products and raw materials (including coke) with a turnover above one year, which is recorded in the statement of financial position and against account is the cost of sales.

The cost of sales of the Company includes inventory costs, outbound freight charges, purchasing and receiving costs, inspection costs, and warehousing costs in cost of goods sold. Vendor payment incentives are recorded as a reduction to cost of goods sold.

Property, plant and equipment

f. Property, plant and equipment – Property, plant and equipment are recorded at acquisition cost less any recognized impairment loss. Cost includes all expenses related with acquisition and installation and, for qualifying assets, borrowing costs (interest) capitalized in accordance with the Company’s accounting policy. Depreciation is recognized so as to write off the cost of assets (other than land and properties under construction) less their residual values over their useful lives, using the straight-line method, and commences when the assets are ready for their intended use. The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period, with the effect of any change in estimates accounted for on a prospective basis.

An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in profit or loss.

The initial estimated useful lives of the Company’s main assets are as follows:

	Years
Buildings	10 to 65
Machinery and equipment	5 to 40
Transportation equipment	4
Furniture, mixtures and computer equipment	3 to 10

Repair and maintenance costs that significantly increase productive capacity or extend the useful lives of existing plant and equipment are capitalized. Supplies, comprising of spare parts and consumables for internal use are classified under property, plant and equipment and expensed as incurred in the manufacturing process. All other repair and maintenance costs are expensed as incurred. Capital expenditures for projects that cannot be put into use immediately are included in constructions and machinery in-progress. When constructions and machinery in-progress are completed, they are transferred to depreciable assets.

Leases

g. Leases – Leases are classified as financial leases when the terms of the lease contract substantially transfer to tenants all the risks and benefits inherent in the property. All other leases are classified as operating leases.

Operating lease payments are recognized as an expense on a straight-line basis over the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred.

In the event that lease incentives are received to enter into operating leases, such incentives are recognized as a liability. The aggregate benefit of incentives is recognized as a reduction of rental expense on a straight-line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.

Costs for loans

h. Costs for loans – Costs for loans directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are ready for their intended use or sale.

Investment income earned on the temporary investment of specific loans pending their expenditure on qualifying assets is deducted from the costs for loans eligible for capitalization.

All other costs for loans are recognized in profit or loss in the period in which they are incurred.

Intangible assets

i. Intangible assets – Intangible assets with definite useful lives that are acquired separately are carried at cost, less accumulated amortization and accumulated impairment losses. Amortization is recognized on a straight-line basis over their estimated useful lives. The estimated useful life and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for, on a prospective basis. Intangible assets with indefinite useful lives that are acquired separately are carried at cost less accumulated impairment losses.

Expenditure on research activities is recognized as an expense in the period in which it is incurred.

An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognized if, and only if, all of the following have been demonstrated:

- The technical feasibility of completing the intangible asset so that it will be available for use or sale;

- The intention to complete the intangible asset and use or sell it;

- The ability to use or sell the intangible asset;

- How the intangible asset will generate probable future economic benefits;

- The availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and

- The ability to measure reliably the expenditure attributable to the intangible asset during its development.

The amount initially recognized for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally-generated intangible asset can be recognized, development expenditure is recognized in profit or loss in the period in which it is incurred. Subsequent to initial recognition, internally-generated intangible assets are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss.

Goodwill

j. Goodwill – Goodwill arising on a combination of business is carried as an asset at cost as established at the date of acquisition of the control of the business less accumulated impairment losses, if any. For the purposes of impairment testing, goodwill is allocated to each of the Company’s cash-generating units that would be expected to benefit from the synergies of the combination. A cash-generating unit to which goodwill has been allocated is tested for impairment annually, or more frequently when there is indication that the unit may be impaired. If the recoverable amount of the cash-generating unit is less than it´s carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro rata based on the carrying amount of each asset in the unit. An impairment loss recognized for goodwill is not reversed in subsequent periods. On disposal of the relevant cash-generating unit, the attributable amount of goodwill is included in the determination of the profit or loss on disposal.

Impairment of tangible and intangible assets other than goodwill

k. Impairment of tangible and intangible assets other than goodwill – At the end of each reporting period, the Company reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any of such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified. Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually, and whenever there is an indication that the asset may be impaired. Recoverable amount is the higher of fair value less costs to sell and value in use. 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 for which the estimates of future cash flows have not been adjusted. If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than it´s carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease. Where an impairment loss subsequently reverses, the carrying amount of the asset (or a cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. For purposes of allocation of goodwill when there is business combination will be distributed among each of the cash generating units of the acquiring entity, expected synergy benefits. A reversal of an impairment loss is recognized immediately in profit or loss and allocated to the assets of that unit, the carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss of value shall not exceed the carrying amount that would have been obtained if had not recognized an impairment loss in value for the asset in prior periods. Unless the related asset is recognized at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase.

Provisions

l. Provisions – Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that the Company will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the balance sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, it´s carrying amount is the present value of those cash flows.

Employee benefits

m. Employee benefits – The costs of direct benefits and defined benefit and defined contribution retirement plans are recognized as an expense when employees have rendered service entitling them to the right to receive those benefits.

The retirement benefit liability is determined based on the present value of the defined benefit obligation at the date of the statement of financial position. Any compensation included in the determination of the liability premiums corresponds to seniority premiums for retirement. Actuarial gains and losses are recognized on profit or loss for the year. The retirement benefit liability and the related net cost of the period are determined under the Projected unit credit method based on projected salaries and certain assumptions determined by independent actuaries.

Liabilities for employee benefits recognized in the consolidated statement of financial position represent the present value of the defined benefit obligation.

Republic operates various employee benefit plans. The contributions to these benefit plans are either contractually determined by the terms of a collective bargaining agreement with the United Steelworkers or they are under the terms of a defined contribution plan. Accordingly, the company pays fixed contributions to separate entities and they are expensed in the period in which the employees rendered the services entitling them to the benefits.

Earnings per share

n. Earnings per share – Income per share is calculated by dividing net income related to the controlling interests, by the weighted average shares outstanding during each year presented.

Income taxes

o. Income taxes – Income taxes represents the sum of the tax currently payable and deferred tax.

- Current tax – The Company incurs Income Tax (ISR) (See note 15) which is recorded in the result in the year in which it is determined. Determined ISR is based on fiscal earnings. Fiscal earning differs from the gain reported in the Consolidated Comprehensive Income Statement, due to taxable income or deductible expenses in other years and items which are never taxable or deductible. The tax liability for the Company is computed using statutory rates promulgated or substantially approved at the end of the period on report.

- Deferred tax –Deferred tax is recognized on differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax basis using the liability method. Deferred tax liabilities are generally recognized for all taxable temporary differences, and deferred tax assets are generally recognized for all deductible temporary differences to the extent that it is probable that taxable profits will be available against which those deductible temporary differences can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable earnings will be available to allow all or part of the asset to be recovered.

Deferred tax assets and liabilities are computed using the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the balance sheet date. The effects of changes in the statutory rates are accounted for in the period that includes the enactment date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its current tax assets and liabilities on a net basis.

The Company follows the practice of recognizing the benefit from the amortization of acquired or generated tax losses in current earnings that are amortized.

- Current and deferred tax for the period – Current and deferred tax are recognized as an expense or income in periodic profit or loss, except when they relate to items that are recognized in other comprehensive income (loss) or directly in equity, in which case, the current and deferred tax are also recognized in other comprehensive income (loss) or directly in equity, respectively.

- Interests on recoverable tax balances – Interest on recoverable tax balances are presented in the consolidated statements of comprehensive income as interest income.

Foreign currencies

p. Foreign currencies – In preparing the financial statements of each individual group entity, transactions in currencies other than the entity’s functional currency (foreign currencies) are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are retranslated at the rates prevailing at that date. In the case of non-monetary items, which arise from the payment or collection of anticipated considerations, are recognized at the exchange rate in force of the date of the transaction.

Exchange differences are recognized in profit or loss in the period in which they arise except for:

- Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings;

- Exchange differences on transactions entered into in order to hedge certain foreign currency risks; and

- Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to profit or loss on sell all or part of the net investment.

Financial instruments

q. Financial instruments – Financial assets and financial liabilities are recognized when a group entity becomes a part to the contractual provisions of the instrument.

Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.

Financial assets

r. Financial assets – Financial assets are classified into the following specified categories: “financial assets at fair value through profit or loss”, “held-to-maturity investments”, “available-for-sale financial assets” and “loans and receivables”. The classification depends on the nature and purpose of the financial assets and is determined at the time of initial recognition. All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the time frame established by regulation or convention in the marketplace.

The effective interest method is a method of calculating the amortized cost of a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, (where appropriate), a shorter period, to the net carrying amount on initial recognition.

The Company does not have financial assets classified as “available-for-sale financial assets”.

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and accounts receivable are measured at amortized cost using the effective interest method, less any impairment.

Financial assets are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected.

Objective evidence of impairment could include:

- Significant financial difficulty of the issuer or counterparty;

- Breach of contract, such as a default or delinquency in interest or principal payments;

- It becoming probable that the borrower will enter bankruptcy or financial re-organization; or

- The disappearance of an active market for that financial asset because of financial difficulties.

For certain categories of financial assets, such as trade receivables, assets that are assessed not to be impaired individually are, in addition, assessed for impairment on a collective basis. Objective evidence of impairment for a portfolio of receivables could include the Company’s past experience of collecting payments, as well as observable changes in national or local economic conditions that correlate with default on receivables.

For financial assets carried at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate.

The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in profit or loss.

Except for equity instruments available for sale, if, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through profit or loss to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed what the amortized cost would have been had the impairment not been recognized.

The Company recognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. If the Company neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Company recognizes its retained interest in the asset and an associated liability for amounts it may have to pay. If the Company retains substantially all the risks and rewards of ownership of a transferred financial asset, the Company continues to recognize the financial asset and also recognizes a collateralized borrowing for the proceeds received.

On recognition totally a financial asset, the difference between the asset’s carrying amount and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income and accumulated in equity is recognized in profit or loss.

Financial liabilities

s. Financial liabilities – Debt and equity instruments issued by a group entity are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument. Financial liabilities are classified as either financial liabilities “at fair value through profit or loss” or “other financial liabilities”.

Financial liability at fair value with changes through profit or loss is a financial liability classified as held for trading or it is designated as at fair value with changes through profit or loss.

A financial liability is classified as held for trading if:

- It has been acquired principally for the purpose of repurchasing it in the near term;

- On initial recognition, it is part of a portfolio of identified financial instruments that the Company manages together and has a recent actual pattern of short-term profit-taking; or

- It is a derivative that has not been designated as a hedging instrument and fulfils the condition to be effective.

- A financial liability other than a financial liability held for trading may be designated as at fair value through profit or loss upon initial recognition if:

o Such  designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise;

o The  financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Company’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or

o It  forms part of a contract containing one or more embedded derivatives, and IAS 39, Financial Instruments: Recognition and Measurement, permits the entire combined contract (asset or liability) to be designated as at fair value through profit or loss.

- Financial liabilities at fair value through profit or loss are recorded at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in profit or loss incorporates any interest paid on the financial liability and is included in the ‘other gains and losses' line item in the consolidated statement of comprehensive income.

- Other financial liabilities including borrowings are subsequently measured at amortized cost using the effective interest method. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or (where appropriate a shorter period), to the net carrying amount on initial recognition.

- The Company derecognizes financial liabilities when, and only when, the Company’s obligations are discharged, cancelled or they expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in profit or loss.

Derivative financial instruments

t. Derivative financial instruments – The Company sometimes uses derivative financial instruments for hedging risks associated with natural gas prices; this commodity is used for the production of goods, for which it conducted studies on historical consumption, future requirement and commitments acquired, thus diminishing its exposure to risks other than its normal operating risks.

These derivatives are initially recognized at fair value at the date the derivative contracts are entered into and subsequently are remeasured to the fair value at the end of reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

To mitigate the risks associated with changes in natural gas prices occurring naturally as a result of the supply and demand on international markets, the Company uses natural gas cash-flow exchange contracts or natural gas swaps to offset fluctuations in the price of natural gas, whereby the Company receives a floating price and pays a fixed price. Fluctuations in natural gas prices from volumes consumed are recognized as part of the Company’s operating cost.

At the inception of the hedge relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument is highly effective in offsetting exposure to changes in fair values or cash flows of the hedged item attributable to the hedged risk.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income and accumulated under the heading of fair value of derivative financial instruments, net of the corresponding income taxes. The gain or loss relating to the ineffective portion of hedge instrument is recognized immediately in profit or loss, and is included in the cost of sales line item.

The Company periodically evaluates the changes in cash flows of the derivative instrument to analyze if the swaps are highly effective for mitigating the exposure to natural gas price fluctuations. A hedge instrument is considered to be highly effective when changes in its fair value or cash flows of the primary position are compensated on a regular or cumulatively basis, by changes in fair value or cash flows of the hedging instrument in a range between 80% and 125%.

Amounts previously recognized in other comprehensive income are reclassified to profit or loss in the periods when the hedged item is recognized in profit or loss, in the same line of the consolidated statement of comprehensive income as the recognized hedged item. However, when the hedged forecasted transaction results in the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in equity are transferred from equity and included in the initial measurement of the cost of the non-financial asset or non-financial liability.

Hedge accounting is discontinued when the Company revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exerted, or when it no longer qualifies for hedge accounting. Any gain or loss accumulated from the hedge instrument that had been recognized in other comprehensive income and accumulated in equity at that time remains in equity until the forecast transaction is ultimately recognized in profit or loss. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

Revenue recognition

u. Revenue from contracts with customers – The income derived from contracts with customers is recognized at the moment in which the control of the goods or services is transferred to the client for an amount that reflects the consideration to which the company expect to have rights, in exchange for those goods and services.

Sale of goods:

Revenues from the sale of the products manufactured by the company ("products") are recognized at the time the asset control is transferred to the customer. The normal credit term on the sale of products is 30 to 90 days after delivery.

The Company considers that there are no other obligations to be fulfilled in the contracts, which are obligations to be fulfilled separately and in which a portion of the transaction price should be allocated. When determining the transaction price for the sale of products, the Company would consider the possible effects of the variable consideration, the existence of important financing components, the consideration other than cash and the consideration payable to the client.

Contract balances

Contractual assets

An asset of the contract is the right to obtain a consideration in exchange for the goods or services transferred to the client. If the Company fulfills an obligation when transferring goods or services to a customer before the customer pays the consideration or before the collection is due, an asset derived from the contract is recognized for the conditional consideration that the Company is entitled to collect.

Accounts receivable

An account receivable represents the company's right to collect a consideration that is unconditional, that is, only the passage of time is required so that the payment of the consideration is payable.

Contract liabilities and customer advances

A liability of the contract is the obligation to transfer control over goods or services to a customer, in the future, that arises from a collection right. If a customer pays the consideration before the Company transfers the goods or services, a contract liability is recognized when the payment is due and an advance from the client when the payment is made. Contract liabilities (or a customer's advance) are recognized as income when the Company fulfills its obligations under the contract.

Financial information by operating segment

v. Financial information by operating segment - An operating segment is an identifiable component of the Company that performs business activities, from which it may earn revenues and incur expenses, including those income and expenses related to transactions with other components of the entity and upon which the company has separate financial information that is evaluated regularly by the Board of Directors, in making decisions to allocate resources and assess segment performance.

Environmental liabilities

w. Environmental liabilities - The Company and other steel companies are subject to stringent environmental laws and regulations. It is the policy of the Company to endeavor to comply with applicable environmental laws and regulations. The Company established a liability for an amount which the Company believes is appropriate, based on information currently available, to cover costs of environmental remediation it deems probable and estimable. The liability represents an estimate of the environmental remediation costs associated with the required future steps of remediation, based upon management's evaluation of probable outcomes. These estimates are based on currently available facts, existing technology and presently enacted laws and regulations. The precise timing of remediation activities cannot be reliably determined at this time due to the absence of any deadlines for remediation under the applicable environmental laws and regulations pursuant to which such remediation costs will be expended. Accordingly, the Company has not discounted its environmental liabilities. Currently no claims for recovery are netted against the recorded liabilities.

Cost of sales and expenses by function

x. Cost of sales and expenses by function - The Company classifies its costs and expenses by function in the Consolidated Statements of Comprehensive Income, according to the industry practices where the Company operates.
