GRUPO IMSA, S.A. DE C.V.

(the Company)

Form 20-F



ACCOUNTING PRINCIPLES



The
Company maintains its financial books and records in pesos and presents its financial statements in conformity with Mexican Generally Accepted Accounting Principles (Mexican GAAP). Mexican GAAP differ in some important respects from
United States Generally Accepted Accounting Principles (U.S. GAAP). See Note 19 to the Consolidated Financial Statements of the Company included herein for a description of the principal differences between Mexican GAAP and U.S. GAAP as
they relate to the Company and for a reconciliation of net income and total stockholders equity for the periods and at the dates indicated.



The Mexican Institute of Public Accountants has issued Bulletin B-10, Recognition of the Effects of Inflation on Financial Information
(Bulletin B-10), Bulletin B-12, Statements of Changes in Financial Position (Bulletin B-12) and Bulletin B-15, Foreign Currency Transactions and Translation of Financial Statements of Foreign
Subsidiaries (Bulletin B-15) (See Notes 2.b and 3.a to the Consolidated Financial Statements). These bulletins outline the inflation accounting methodology mandatory for all Mexican companies reporting under Mexican GAAP. The Third
Amendment to Bulletin B-10 (the Third Amendment), which has been effective since January 1, 1990, requires that all financial information be presented in constant pesos (having the same purchasing power for each period indicated taking
inflation into account) as of the date of the most recent balance sheet presented. Pursuant to Mexican GAAP, all financial data in the Companys consolidated financial statements as of December 31, 2002 and December 31, 2003 and for each of the
years in the three years ended December 31, 2003 (the Consolidated Financial Statements) and the related notes thereto included therein and, unless otherwise indicated, throughout this annual report, have been restated in constant pesos
as of December 31, 2003.



CURRENCY



References herein to
US$, U.S. dollars, dollars or $ are to the lawful currency of the United States. References herein to pesos or Ps are to the lawful currency of Mexico.



EXCHANGE RATES



This annual
report contains translations of certain peso amounts into U.S. dollars at specified rates solely for the convenience of the reader. These translations should not be construed as representations that the peso amounts actually represent such U.S.
dollar amounts or could be converted into U.S. dollars at the rate indicated or any other rate. Unless otherwise indicated, such U.S. dollar amounts have been translated from pesos at an exchange rate of Ps 11.2360 to $1.00, the noon buying rate on
December 31, 2003 announced by the Mexican central bank (Banco de Mexico). On June 14, 2004, the rate for Mexican pesos was Ps 11.3689 to $1.00. See Item 3. Key InformationSelected Financial DataExchange Rate for
information regarding exchange rates since January 1, 1999.

the result of any revisions to these forward-looking statements which may be made to reflect events or circumstances after the date hereof, including, without limitation, changes in the Companys business strategy or planned capital

Item 3Key Information



A.Selected Financial Data



The following table presents selected consolidated financial information and data for the Company at the dates and for the periods indicated. This information should be read in conjunction with, and is qualified in its entirety by reference
to, the Consolidated Financial Statements and the related notes thereto included elsewhere in this annual report. See Item 8. Financial InformationDividends and Dividend Policy for the Companys dividends and dividend policy.



The Consolidated Financial Statements are prepared and
presented in accordance with Mexican GAAP which differ in certain respects from U.S. GAAP. See Note 19 of the Notes to the Consolidated Financial Statements, which provides a description of the principal differences between Mexican GAAP and U.S.
GAAP, as they relate to the Company, and a reconciliation to U.S. GAAP of net income for the years ended December 31, 2001, 2002 and 2003 and stockholders equity as of December 31, 2001, 2002 and 2003. In accordance with Mexican GAAP, the
Companys financial statements recognize certain effects of inflation and have been restated in constant pesos as of the date of the most recent balance sheet presented. Accordingly, all peso amounts related to the Mexican companies in the
Consolidated Financial Statements and in the selected financial information set forth below have been restated in constant pesos as of December 31, 2003 by applying factors derived from the National Consumer Price Index (NCPI), published
by Banco de Mexico. The operations of foreign subsidiaries and associated companies are not considered an integral part of the Company; thus, the inflation effects confronted by the foreign subsidiaries in their respective countries are applied when
consolidating the financial statements and restated, accordingly, in constant pesos as of the date of the most recent balance sheet presented. The effects of these inflation accounting principles, except for the adjustment related to restatement of
foreign sourced fixed assets, have not been reversed in the reconciliation to U.S. GAAP, as discussed in Note 19 of the Notes to the Consolidated Financial Statements.

Exchange Rate



In December 1994, the Mexican government decided to suspend intervention by
Banco de Mexico and to allow the peso to float freely against the dollar. There can be no assurance that the Mexican government will maintain its current policies with regard to the peso or whether the peso will depreciate or appreciate
significantly in the future.

Except for the period from September 1 through December 20, 1982, during the Mexican liquidity crisis, Banco de Mexico consistently has made foreign
currency available to Mexican private sector entities (such as the Company) to meet their foreign currency obligations.



The Company conducts substantially all of its business in either pesos or dollars. Some of the Companys subsidiaries maintain a favorable commercial
trade position in dollars. This position motivated the Company to enter into forward contracts establishing a fixed exchange rate for each transaction (Forward Contracts). In accordance with the terms of these Forward Contracts, the
Company is required to sell the dollar amount at the contractual exchange rate. If the exchange rate in the market on the due date is below the agreed fixed exchange rate, the Company receives the spread; and if the exchange rate is above the agreed
fixed exchange rate, the Company pays the difference. As of December 31, 2003, the total outstanding amount of Forward Contracts was U.S.$50.2 million. As of the same date, the fair value represented a favorable valuation for the Company of U.S.$586
thousand.

D.Risk Factors



Risks Relating to Mexico



The Company is a Mexican corporation which currently conducts most of its
manufacturing activities in, and derives a substantial portion of its sales from, Mexico. The level of manufacturing activity in Mexico has in the past been affected by prevailing conditions in the Mexican economy, and domestic demand (including
domestic demand for the Companys products) has been and is, to a significant extent, vulnerable to economic downturns in Mexico. In addition, the Companys financial condition, liquidity (including its ability to obtain financing) and
prospects have been and are expected to continue to be affected by prevailing economic conditions in Mexico, particularly downturns in the Mexican economy and changes in government policies, including public spending on infrastructure projects. The
discussion of recent developments in Mexico that follows was derived from information filed by the Mexican government and Petróleos Mexicanos (Pemex) with the U.S. Securities and Exchange Commission (SEC). Although the
Company believes this information is reliable, it has not independently verified this information and cannot guarantee that it is accurate.



Economic Situation



Beginning in December 1994 and continuing through 1995, Mexico experienced an economic crisis characterized by exchange rate instability, a devaluation of
the Mexican peso, high inflation, high domestic interest rates, economic contraction, a reduction of international capital flows, reduced consumer purchasing power and high unemployment. In response to the economic crisis, the Mexican government
implemented broad economic reform programs which improved economic conditions in 1996 and 1997. However, a combination of factors led to a reduction in Mexicos economic growth beginning in 1998, including the economic crises in Asia, Russia,
Brazil and other emerging markets that began in late 1997. Mexicos economic growth resumed in 1999 and 2000, but decreased in 2001 during the worldwide recession. See Item 5. Operating and Financial Review and Prospects 
General.

##### Table of Contents

Mexicos gross domestic product (GDP) increased 0.7% in 2002 and increased 1.3% in 2003,
and the annual rate of inflation, as measured by changes in the Consumer Price Index, was 3.98% in 2003. In 2004, according to Mexican government estimates, GDP growth is expected to be approximately 3% to 3.5%, and the inflation rate is estimated
to be 3%. Interest rates on 28-day Mexican treasury bills, or Cetes, averaged 7.1% in 2002 and 6.23% in 2003. On June 15, 2004, the interest rate on 28-day Cetes was 6.54%. These estimates for 2004 may be revised and,
whether or not they are revised, actual results may differ from estimates.



A deterioration in Mexicos economic conditions, similar to that experienced from the end of 1994 through 1995, could adversely affect the Companys business, results of operations, financial condition,
liquidity and prospects. For example, adverse economic conditions in Mexico could result in reduced domestic consumption of the Companys products, higher interest rates accompanied by reduced opportunities for refunding or refinancing, foreign
exchange losses associated with dollar-denominated debt, increased raw materials and operating costs, decreased operating results and delays in capital expenditures dependent on U.S. dollar purchases of equipment. Severe devaluation of the peso may
also result in disruption of the international foreign exchange markets, hindering the Companys ability to convert pesos into U.S. dollars and other currencies for the purpose of making timely payments of interest and principal in respect of
its indebtedness or purchases of raw materials or equipment. Depending on their severity and duration, these consequences could have a material adverse effect on the Companys business, results of operation, financial condition, liquidity and
prospects. See Item 5. Operating and Financial Review and Prospects  General.



Government Control of the Economy



The Mexican government has exercised, and continues to exercise, significant influence over the Mexican economy. Mexican government actions concerning the economy may have adverse effects on private sector entities in
general and on the Company in particular. Economic plans of the Mexican government in the past have not, in many respects, fully achieved their objectives, and these and other economic plans of the Mexican government may not achieve their stated
goals. Similarly, it is not possible to determine what effect such plans or the implementation thereof will have on the Mexican economy or on the Companys financial condition or results of operations.



Political Events



Mexican political events may also affect the Companys financial condition and results of operations and the
performance of securities issued by Mexican companies. The Mexican political environment is in a period of change. In July 2000, Vicente Fox, a member of the National Action Party (Partido Acción Nacional) (PAN), the oldest
opposition party in the country, won the Presidential election. He took office on December 1, 2000, ending 71 years of rule by the Institutional Revolutionary Party (Partido Revolucionario Institucional) (PRI).



In the Congressional election held on July 6, 2003, all of the seats in the
Chamber of Deputies were up for election. The following table provides the distribution of Congressional seats as of September 1, 2003.

##### Table of Contents

The success of political opposition parties in recent elections may result in changes in Mexicos
economic policies. Currently, no party has a working majority in either house of the Mexican Congress, which has made governability and the passage of legislation more difficult.



Risks Relating to Other Latin American Countries



Certain of the Companys subsidiaries are located in other Latin American countries, including Brazil, Chile and
Guatemala, and a portion of the Companys exports are made to Latin American countries. In recent years, some of these countries have been adversely affected by political and economic conditions and government policies. In each of these
countries, conditions such as currency fluctuations, inflation and interest rates, social instability, government policies such as wage and price controls, exchange controls or tax increases, or other political, economic or social developments,
could have a material adverse effect on the Companys operations and export revenues. In addition, devaluation of any of the local currencies could adversely affect the Companys consolidated financial condition and results of operations.
The Company has from time to time experienced an impact as a result of adverse conditions elsewhere in Latin America. For example, battery sales in Argentina declined in 2002 as a result of the crisis in that nation. Although to date the Company has
not experienced a material adverse effect as a result of conditions in other Latin American countries, extreme conditions affecting one or more of the Companys subsidiaries or exports of one or more of the Companys products could have a
material adverse effect on the Companys business and results of operations.



Risks Relating to Cyclicality in the Demand for the Companys Products



The industries in which the Company operates are cyclical. The financial condition and results of operations of companies in these industries are
generally affected by general economic conditions and other factors in the countries in which their products are sold, including fluctuations in GDP, related market demand, global production capacity and other factors beyond the Companys
control. The demand for, and prices of, the Companys products are directly affected by these fluctuations. Many of the Companys subsidiaries are highly dependent on construction activity, which is cyclical and is significantly affected
by changes in general and local economic conditions. A prolonged recession in the construction industry in Mexico or the United States could result in a significant decrease in the Companys operational performance. There can be no assurance
that events having an adverse effect on the industries in which the Company operates may not occur or continue, such as another downturn in the Mexican or world economies, an increase in imports of competing products into Mexico, an increase in
production resulting in over-supply in the markets in which the Company sells its products, unfavorable currency fluctuations or an increase in domestic competition in the Mexican market.



Risks Relating to Competition



In 2002 and 2003, net sales in the Mexican market accounted for approximately 46.1% and 46.0%, respectively, of the Companys net sales. In
Mexico, the industries in which the Company operates are characterized by a high degree of competition from domestic and foreign manufacturers, some of which have greater resources than the Company. Competitors are continually undertaking
modernization and expansion plans, including the installation of production facilities and manufacturing capacity for certain products that will compete with the Companys and, in certain cases, undertake strategic alliances with foreign
competitors. As a result, the Company may experience increased competition in Mexico as its competitors plans are completed. The Company also faces significant competition in other countries in which it operates, particularly in the United
States, where a significant portion of the Companys operations are situated. See Item 4. Information on the CompanySteel Processing ProductsCompetition, Automotive Batteries and Related
ProductsCompetition, Steel and Plastic Construction ProductsCompetition, and Aluminum and Other Related ProductsCompetition below.



In the ten years since the North American Free Trade Agreement
(NAFTA) became effective, Mexican products have consolidated in the North American market, positioning Mexico as the second or third largest trade partner of the United States. There are no barriers to free trade among the three member
countries of NAFTA, the United States, Canada and Mexico. There are no duties for steel products, automotive batteries or construction related products, including the Companys products. As a result of NAFTA, some products, including the
Companys products, have been subject to price pressures and may continue in the future to be subject to these price pressures. The Company does not believe, however, that these price pressures have to date materially affected its competitive
position in the products which it produces and which are subject to free trade under NAFTA.



The Free Trade Agreement between the European Union and Mexico became effective on July 1, 2000. As a result, since January 1, 2003, Mexican products including flat steel products have been able to enter the European
market free of

any duties. Products from the European Union, on the other hand, are subject to different duty-reduction schedules,
achieving free access to the Mexican market by 2007. Flat steel and construction-related products imported into Mexico from the European Union will be duty free in 2007. The Company is not able to predict what impact elimination of duties on
products imported from the European Union will have on the Companys business, results of operation or financial condition.



There are currently no countervailing duties on Mexican flat steel products nor any ongoing processes that could result in a potential obstacle to their
access to the United States, Canada or Latin American markets. Furthermore, automotive batteries and the rest of the Companys products are not subject to any countervailing duties under NAFTA or in Latin America.



Articles 303 and 304 of NAFTA sharply curtail the waiver by NAFTA countries
of duties on material, parts, machinery and equipment imported from outside of North America that are used to produce finished goods exported to the other NAFTA countries. Since January 1, 2001, the amount of import duties on material, parts and
components waived by Mexico has been limited to the lesser of the Mexican import duties accrued or the U.S. or Canadian duties on the finished product when imported from Mexico. Mexico has sought to deal with this limitation by establishing a sector
program called PROSEC, which allows 23 industrial sectors in Mexico to import parts, components and machinery at duties ranging from 0% to 5%. This program is in compliance with NAFTA and World Trade Organization (WTO) rules
since the lower duties are not tied to export performance. Flat steel products are included in PROSEC. The Company believes that it experiences increased competition from suppliers to those Mexican industrial sectors covered by PROSEC that are able
to import steel products from non-NAFTA countries at duties ranging from 0% to 5%.



On June 5, 2001, President George W. Bush announced his plans for addressing the problems facing the U.S. steel industry. Part of his plan called for a Section 201 investigation by the United States International
Trade Commission (the ITC). On June 22, 2001, the United States Trade Representative submitted a request to the ITC for a Section 201 investigation. On March 5, 2002, President Bush announced measures that would be implemented in the
United States to protect the nations steel industry, including the application of import tariffs of 30% on flat steel products for the first year, commencing in March 2002, 24% for the second year and 18% for the third year. Mexico was
excluded from such measures. In late 2003, the WTO Appellate Body affirmed that the U.S. safeguard measure on steel was WTO-inconsistent. The Appellate Body ruled that the measure breached a number of the obligations of the United States under the
Agreement on Safeguards. On December 5, 2003, arguing that the safeguard had served its purpose and under pressure from the WTO, the European Union and other countries, President Bush announced his decision to terminate the temporary
safeguard measures on steel which were put in place in March 2002.



In response to the actions that the United States has taken, and in order to avoid a surplus of steel from the international marketplace being dumped in Mexico and damaging the Mexican steel industry, the Mexican government imposed tariffs
on imports from countries that do not have a free trade agreement with Mexico of 25% during the period from September 2002 to September 2003 and 18% during the period from September 2003 to March 2004. These measures helped to discourage steel
imports from some countries. Although tariffs have been restored to their original level of 18% for coated steel and 13% for non-coated steel, respectively, as of the beginning of 2004, imports have declined as a result of the scarcity of steel in
the world market. To the extent steel in the world market becomes less scarce in the future, imports of steel to Mexico may increase resulting in increased competition to the Company. In addition, to the extent there continues to be a scarcity of
raw materials in the future, it likely will become more difficult and more costly to the Company to acquire the raw materials it needs and, therefore, this scarcity may adversely affect the business, results of operation and financial condition of
the Company.



Recently, the ITC preliminarily determined that
dumping with respect to standard and line pipes from Mexico had occurred, and, as a result, imposed an anti-dumping tariff of 11% on Mexican companies that export these products to the United States. Because the standard and line pipes exported by
the Company to the United States represent only a very small portion of its total exports worldwide, the Company has not been materially impacted by the imposition of this tariff and has, since the preliminary determination, ceased exportation of
these products to the United States. The Company does, however, continue to export other products to the United States and to the extent any further anti-dumping claims and tarrifs are imposed by the ITC on these products, the financial results of
the Company could be adversely impacted.



Risks
Relating to Dependence on Limited Amount of Suppliers and Customers



The Companys energy needs are supplied by a limited number of suppliers, and would be seriously affected if these suppliers failed to deliver gas or electricity, due to a shortage or otherwise. Additionally, although IMSA ACEROs
steel needs can be satisfied by a number of companies, if any of its key suppliers failed to deliver, the Company could face

limited access to raw materials, higher raw material costs and delays resulting from the need to redistribute its raw
material needs among other suppliers. Under certain circumstances, such as significant growth in demand around the world, commodities, such as zinc, aluminum and lead, which are some of the most important raw materials for Grupo Imsa, could
experience price increases and limited availability. As a result of a global increase in demand for steel and a limited supply, prices of steel experienced significant growth during the first half of 2004. These effects could have a negative impact
on the financial results of the Company. The Companys results could also be adversely affected if it failed to retain some of its larger customers; however, the Company historically has succeeded in the retention of most of its significant
customers and maintains a large and diverse client base across several industries, which further reduces the potential adverse impact on the Companys business and financial results to the extent in the future it suffers the loss of any larger
customer. For its exports in the United States relating to automotive batteries, the Company relies exclusively on Johnson Controls and GES Battery Systems to purchase its automotive batteries. See Item 7. Major Shareholders and Related Party
TransactionsRelated Party Transactions. Johnson Controls and GES Battery Systems then resell the batteries to retailers. Although the Company currently anticipates that both Johnson Controls and GES Battery Systems will continue to
purchase and distribute the Companys automotive batteries, to the extent either Johnson Controls or GES Battery Systems fails, in the future, to purchase the automotive batteries from the Company, the Company could be adversely impacted if it
was unable to find a third party purchaser to purchase and distribute its product on comparable terms.



Risks Related to Fluctuations in Energy Costs



The cost of natural gas and electricity is an important component of the Companys cost structure. The Company is subject to energy cost fluctuations
and has been previously, as was the case in the second half of 2000, and may be affected in the future by major energy price increases. Natural gas is supplied to the Company by Pemex and electricity has been supplied to the Company by the
Comisión Federal de Electricidad and, since 2003, by Tractebel Energía de Monterrey. See Item 11. Quantitative and Qualitative Disclosures About Market RiskNatural Gas Price Risk.



Risks Relating to Environmental Matters



The Company is subject to a wide range of state and federal laws,
regulations, permits and decrees in Mexico and elsewhere relating to the protection of human health and the environment, including regulations concerning wastewater discharges, air emissions, noise, employee health and safety, soil and groundwater
contamination and the use, handling and disposal of hazardous substances and wastes. State and federal authorities in Mexico and elsewhere have been moving toward more stringent enforcement of these laws. This trend is likely to continue and be
influenced by environmental agreements entered into by Mexico, the United States and Canada in connection with NAFTA. The Company believes that all of its plants, installations and properties are in substantial compliance with all environmental laws
in Mexico and with environmental laws in the other countries in which the Company operates. Therefore, the Company has not established any reserves in respect of potential environmental remediation obligations. However, as with other companies
engaged in similar industries, environmental liability and compliance obligations are inherent in many of our manufacturing-related activities. There can be no assurance, therefore, that remediation or other claims will not be asserted against the
Company and subsidiaries of the Company, that the Company and its operations will not be subject to stricter environmental laws and regulations in Mexico and each of the other jurisdictions in which it operates in the future or that new
environmental remediation obligations will not arise in the future as a result of such stricter laws or regulations, or their interpretation or enforcement. Stricter environmental regulation could increase our compliance and operating costs, affect
our ability to obtain or maintain necessary authorizations or approvals or impose significant unplanned expenditures to remediate environmental damage any of which could have a material adverse effect on the Companys business, financial
condition, results of operations or prospects. See Item 4Information on the CompanyThe CompanyEnvironmental Matters.



Risks Relating to Control by Principal Stockholders



The principal stockholders of the Company currently control 84.2% of the outstanding shares of the Company, representing approximately 88.7% of the voting
power of the Company. Accordingly, such individuals are able to elect a majority of the members of the Board of Directors of the Company, have the power to determine the outcome of substantially all other actions requiring the approval of the
Companys stockholders, including the approval of the declaration, amount and payment of dividends and the issuance of debt and equity securities of the Company, and can take actions that do not reflect the will or the best interests of
minority stockholders. See Item 6. Directors, Senior Management and Employees and Item 7. Major Shareholders and Related Party Transactions.

##### Table of Contents

In addition, certain actions by the principal stockholders with respect to the disposition of their
shares might adversely affect the trading price of the equity units (Equity Units) and the American depositary shares (ADSs).



Risks Relating to Inability of ADS Holders to Participate in Preemptive Rights Offerings



Under Mexican law and the Companys by-laws, the stockholders of the
Company have the right to subscribe for shares of stock issued by the Company in an increase of capital (Preemptive Rights). United States holders of ADSs may not be able to exercise (through The Bank of New York (the
Depositary)) their preemptive rights unless a registration statement under the Securities Act is effective with respect to such rights or an exemption from the registration requirements thereunder is available. There can be no assurance
that any such registration statement would be filed. To the extent holders of ADSs are unable to exercise their rights because a registration statement has not been filed and no appropriate exemption from such registration requirements under the
Securities Act is available, the Depositary may attempt to sell such holders preemptive rights and distribute the net proceeds thereof, if any, to the holders of ADSs. If, pursuant to the terms of any rights offering, under the provisions of
Mexican law or for any other reason, the Depositary is unable or chooses not to make such rights available to any holder of ADSs, and if the Depositary is unable under or prohibited by Mexican law from selling such rights or for any reason chooses
not to sell such rights, the Depositary may allow the rights to lapse. In any case when such rights are sold or lapse, the equity interests of the holders of ADSs would be diluted.



Risks Relating to Holding Company Structure



The Company is a holding company with no substantial operations and, consequently, is dependent on dividends, debt and
interest payments and other payments from its subsidiaries and income tax refunds for virtually all of its internal cash flow, including cash flow to pay taxes, service debt, make equity investments, finance the growth of its subsidiaries and pay
dividends to its stockholders. The ability of the Companys subsidiaries to make dividend payments to the Company is limited by Mexican law and by virtue of the compliance by such subsidiaries with financial covenants under certain debt
instruments. See Item 5. Operating and Financial Review and ProspectsLiquidity and Capital ResourcesFinancing Activity and Holding Company Liquidity.



Risks Relating to Limitations on the Payment of Dividends



The Companys ability to pay dividends is restricted by Mexican law.
See Item 8. Financial InformationDividends and Dividend Policy. The declaration, amount and payment of dividends are determined by majority vote of the holders of Series B Shares, generally, but not necessarily, on the
recommendation of the Board of Directors; the Companys principal stockholders have the ability to elect the majority of the members of the Board of Directors of the Company and, as a result, will have the power to determine the outcome of
actions requiring the approval of the Board of Directors and the stockholders, including the declaration of dividends. See Risks Relating to Control by Principal Stockholders above. There can be no assurance as to the amount, if
any, of dividends that will be paid by the Company in any given year.



Risks Relating to the Effects of Exchange Rates and Exchange Controls on Holders of ADSs



The value of the peso has been subject to significant fluctuations with respect to the U.S. dollar in the past and may be subject to significant
fluctuations in the future. Fluctuations in the exchange rate between the peso and the dollar will affect the U.S. dollar value of an investment in the ADSs or the Equity Units and of dividends and other distributions thereon. See Item 3. Key
InformationSelected Financial DataExchange Rate. In addition, the Depositary will convert pesos into U.S. dollars (to the extent that U.S. dollars are available) at the interbank rate for the purpose of making dividend and other
distribution payments on the ADSs, and any restrictive exchange control policy which might be implemented by the Mexican government in the future would adversely affect the Depositarys ability to convert dividends received in pesos into
dollars for purposes of making distributions to holders of ADSs.



Risks Relating to Limited Trading Market for ADSs and Equity Units



The markets for the ADSs and Equity Units have not been very liquid and may in the future continue to lack liquidity. As of April 22, 2004, approximately 15.8% of the Companys capital stock is held by the public
and is traded on the Mexican Stock Exchange and the New York Stock Exchange (NYSE). In addition, the Mexican securities market is not as large or as active as the securities markets in the United States and certain other developed market
economies. As a result, the Mexican securities market has experienced less liquidity and more volatility than has been experienced in these other markets. These market characteristics may limit the ability of a holder of ADSs to sell the underlying
Equity Units and may also affect the market price of the Equity Units and the ADSs.

Risks Relating to Corporate Disclosure, Protection of Minority Stockholders and Accounting Standards



A principal objective of the securities laws of Mexico,
like those of the United States, is to promote the full and fair disclosure of all material information. There may, however, be less publicly available information about Mexican issuers of securities than is regularly published by or about U.S.
issuers, and the information may only be available in Spanish. Further, Mexican regulations governing the securities of Mexican companies may not be as extensive as those in effect in the United States. Additionally, although Mexican securities laws
have been amended to provide greater protection to minority stockholders, even as amended, Mexican law and regulations in respect of corporate governance matters might not be as protective of minority stockholders as state corporations laws in the
United States. Also, the accounting standards used in Mexico, in accordance with which the Companys financial statements are prepared, differ in certain material respects from the accounting standards used in the United States. For a
description of the principal differences between Mexican GAAP and U.S. GAAP as they relate to the Company, see Note 19 to the Consolidated Financial Statements.



Risk Relating to Developments in Other Emerging Markets



The Mexican financial and securities markets are, to varying degrees, influenced by economic and market conditions in other emerging market countries.
Although economic conditions are different in each country, investor reaction to developments in one country can have significant effects on the securities of issuers in other countries, including Mexico. For example, in late October 1997, prices of
both Mexican debt securities and Mexican equity securities dropped substantially, precipitated by a sharp drop in value of Asian markets. Similarly, in the second half of 1998 prices of Mexican securities were adversely affected by the economic
crises in Russia and in Brazil. The Mexican financial and securities markets have also been affected by events elsewhere in the world, such as the September 11, 2001 terrorist attacks and the worldwide recession which followed. In the event that the
Mexican financial and securities markets are adversely affected by events elsewhere, the market value of the Companys shares and ADSs may also be adversely affected.



Risk Relating to Judgment Enforcement in U.S. Courts



The Company is a corporation organized under the laws of Mexico, and most of the Companys assets are located in
Mexico. Furthermore, most of the Companys directors and officers and some experts named in this annual report reside in Mexico, and a substantial portion of their assets are located in Mexico. As a result, investors may not be able to effect
service of process within the United States upon the Company or the Companys directors or officers or certain experts or to enforce against the Company or such directors, officers or experts in U.S. courts judgments predicated upon the civil
liability provisions of U.S. federal securities law. There is doubt as to the enforceability in original actions in Mexican courts of civil liabilities predicated solely upon U.S. federal securities laws, and the enforceability in Mexican courts of
judgments entered by U.S. courts predicated upon the civil liability provisions of the U.S. federal securities law will be subject to compliance with procedural requirements under Mexican law, including the condition that such judgments do not
violate Mexican public policy.



Item 4Information on the Company



Overview



The Company is one of the largest
diversified industrial companies in Mexico in terms of sales (based on information published by the Mexican Stock Exchange and by business magazines such as America Economíaand Expansión) and conducts its business in
four segments: steel processing products (approximately 47% of consolidated 2003 net sales), steel and plastic construction products (approximately 28% of consolidated 2003 net sales), automotive batteries and related products (approximately 15% of
consolidated 2003 net sales), and aluminum and other related products (approximately 10% of consolidated 2003 net sales). In 2003, the Company had consolidated net sales of Ps 31,230 million ($2,779 million) and operating income of Ps 2,459 million
($219 million). The Company has expanded internationally by increasing exports as well as by adding manufacturing facilities in South and Central America and the United States. Foreign company and export sales accounted for approximately 54% of the
Companys consolidated net sales in 2003.

History and Development of the
Company



The Company was founded in Monterrey, Mexico, as
Industrias Monterrey, S.A. (IMSA) in 1936 and grew significantly as a steel processor during World War II and in subsequent years. The Company changed its name to Grupo Imsa, S.A. de C.V. in 1984. The Company shall have a term of 99
years from May 19, 1997. The Companys headquarters are located in leased offices at Avenida Batallón de San Patricio No. 111, Piso 26, Fracc. Valle Oriente, San Pedro, Garza García, N.L. 66269 Mexico, and the Companys
telephone number is (5281) 8153-8300.

##### Table of Contents

The Company now conducts its steel processing business through four operating subsidiaries, IMSA-MEX,
Steelscape, Industria Galvanizadora and Imsa, Inc. which are consolidated under two holding companies, IMSA ACERO and Ecore Holding (Ecore). IMSA ACERO owns the shares of IMSA-MEX and Industria Galvanizadora while Ecore owns the shares
of Steelscape and Imsa, Inc. Although Ecore is not legally part of IMSA ACERO, in this annual report, references to IMSA ACERO shall include Ecore unless otherwise indicated. Historically, the Company conducted its steel operations through IMSA. In
1991, one of the predecessors of IMSA-Mex, APM, S.A. de C.V. (APM), was created to purchase from the Mexican government the flat steel production facility of Fundidora Monterrey, S.A. The investment in APM was strategically important
because it enabled the Company to assure the availability and control the quality of hot- and cold-rolled flat steel feedstock, the principal raw materials for IMSAs galvanizing operations, at a reasonable cost. As part of its strategic
outlook, the Company embarked on a modernization program at APM, installing technologically advanced process control equipment to enable APM to produce high-quality hot- and cold-rolled flat steel and to be positioned to compete globally. In July
1997, the Company, through IMSA ACERO, acquired Industria Galvanizadora, a Guatemalan steel processor. In February 1999, IMSA ACERO acquired 100% of the assets of a galvanizing and painting steel plant from Altos Hornos de Mexico, S.A. de C.V.
(AHMSA). In 2000, IMSA ACERO acquired 100% of the stock of Steelscape, formerly BHP Coated Steel Corporation (BHP). The acquisition gave IMSA ACERO operations on the West Coast of the United States for pickling hot-rolled
steel sheet, for producing cold-rolled steel sheet, for producing galvanized sheet and Galvalume, and for manufacturing pre-painted sheet. In June 2002, the Company, through IMSA ACERO, acquired certain assets of Pinole Point Steel from Material
Sciences Corporation. This acquisition primarily consisted of a galvanized and painted steel plant in Richmond, California. The new plant increased Steelscapes steel-painting capacity, which had previously been operating at full capacity, and
contributed to improving IMSA ACEROs product mix. On January 1, 2003, IMSA ACERO merged IMSA and APM into a new entity called IMSA-MEX which now controls IMSA ACEROs operations in the Mexican market. IMSA ACERO maintains IMSA and APM as
separate divisions so that its uncoated and coated segments are operated separately in order to continue to offer first-class service to its different markets.



The Company entered the automotive batteries and related products business in 1987 with the acquisition of Acumuladores Mexicanos, S.A. de C.V. and
Acumuladores del Centro, S.A. de C.V. Since then, the Companys automotive batteries and related products segment has grown significantly in terms of production capacity and geographic diversification through several strategic acquisitions,
investments and joint ventures. These include principally the acquisition of Acumuladores Monterrey, S.A. de C.V., a large Mexican original equipment manufacturer (OEM); the acquisition of automotive battery manufacturers in South
America; and the acquisition of Advantage Battery Corporation, a U.S. automotive battery distributor. In December 1998, through ENERMEX, the Company formed a joint venture with Johnson Controls, Inc. (Johnson Controls) and Varta AG
(Varta) to produce and/or distribute automotive batteries throughout the American continent. This alliance has the largest battery production capacity in Latin America (based on the Companys market share analysis in major Latin
American countries). The Company joined Johnson Controls in North America and Johnson Controls and Varta in South America. The Company believes the economies of scale and integration of production facilities has resulted and will continue to result
in an improved cost structure and will continue to strengthen its commercialization network in the region. In October 2002, Johnson Controls acquired Vartas Automotive Battery Division. Today, the Company conducts its automotive batteries and
related products business through ENERMEX, the holding company for the subsidiaries in this product segment.



The steel and plastic construction products segment was originally part of the steel processing products segment, which began manufacturing value-added
steel processing products such as culverts, guardrails and steel strapping in the 1950s. Beginning in the 1970s, the steel and plastic construction products segment was separated from the steel processing products segment and was established as a
separate business through a series of transfers of various businesses within the corporate structure to the steel and plastic construction products segment. The first transfer was the steel and plastic strapping business, which was incorporated into
IMSA Signode, S.A. de C.V., a joint venture between the Company and the Illinois Tool Works, Inc. Signode Division (ITW), a large United States manufacturer of steel and plastic strapping. The second transfer was of Forjas
Metálicas, a manufacturer of fabricated galvanized steel products. The third transfer was of Multypanel, a manufacturer of prefabricated steel and foam-insulated panels. The steel and plastic construction products segment has also grown
through acquisitions. In 1975, the Company acquired Stabilit, a manufacturer of fiberglass-reinforced plastic (FRP) panels, which subsequently grew through additional acquisitions in Mexico, the United States and Spain. At the end of
1994, the Company acquired Metl-Span Corporation, a U.S. manufacturer of prefabricated steel and foam-insulated panels. In addition, over a period of several years, the Company acquired Empresas Ipac, S.A. (Empresas Ipac), a Chilean
steel processor and manufacturer of prefabricated steel and foam-insulated panels. In March 2000, a new Forjas Metálicas plant in Monterrey, Mexico began producing polygonal

metal poles. In order to consolidate its position in the electricity transmission market and expand its market potential
in poles for the telecommunications and illumination industries, a new company called Valmont Formet was established. The new company is a joint venture with Valmont Industries, a world leader in the pole market (based on information published by
Valmont Industries). In September 2001, the Company acquired the assets of Varco Pruden Buildings, Inc. from the LTV Corporation. Varco Pruden Buildings is the second-largest company in North America in the pre-engineered metal buildings market.
Headquartered in Memphis, Tennessee, it has eight plants in the United States and one in Mexico that produce metal buildings and their components. IMSATEC has a joint venture in Brazil with Grupo Medabil to form Medabil Varco Pruden, which operates
in the metal building business. Varco Pruden Buildings provides integral solutions for the construction of large buildings, such as manufacturing plants, warehouses, commercial facilities, offices, schools and churches. During 2001, the assets of
IMSA Building Products (IBP) were transferred from IMSA ACERO to IMSATEC, and the company was renamed ASC Profiles.



In 1989, the Company entered the aluminum extrusions business through the acquisition of Cuprum, a large Mexican producer of aluminum extrusions. Through
subsequent acquisitions and the establishment of new product lines, Cuprum became a large manufacturer of fabricated aluminum products. Today, Cuprum and its subsidiaries are consolidated under a holding company, IMSALUM, which forms the aluminum
and other related products segment. Other significant acquisitions and joint ventures made through Cuprum in recent years include the acquisition of Davidson Ladders, Inc., which manufactures wood ladders and distributes all types of ladders in the
United States, and the acquisition of certain assets of Stapleton Ladders, a manufacturer of wood attic stairways. Both of these acquisitions complemented the Companys line of ladders. Cuprum also acquired Tiendas Alutodo, a chain of retail
outlets for aluminum products. In April 1998, IMSALUM acquired 100% of the shares of Alcomex, S.A. de C.V. (Alcomex), a producer of industrial aluminum profiles. This acquisition complemented IMSALUMs operations, given
Cuprums focus in the architectonic market. The Company and Emerson Electric Co. merged their ladder businesses, setting up a new company called Louisville Ladder Group, which the Company believes is the second largest ladder producer in the
Americas (based on estimates of the Companys sales force and information from the National Home Centers News Top 500 Annual Report, the RICHMARK Group, Inc. and the Companys customers). The operation included Escaleras and Davidson
Ladders, subsidiaries of IMSALUM, and Louisville Ladder Co., a subsidiary of Emerson Electric Co. On January 9, 2004, the Company completed the acquisition of 49% of the equity of Louisville Ladder Group. The acquisition gave the Company 100%
control of this company through its subsidiary IMSALUM. The Company believes that this acquisition complements its other previous acquisitions and joint ventures in the ladder industry and, because the Company anticipates that this acquisition will
enable it, through its subsidiaries, to achieve greater flexibility with respect to its production and distribution of ladders, bolsters its competitive position with respect to its competitors.



Steel Processing Products



General



The Company believes it is Mexicos largest intermediate flat steel
processor in terms of sales volume (based on public information available regarding AHMSA and Hylsamex, S.A. de C.V. (Hylsamex), the Companys major competitors, each of whose intermediate steel processing segments has a smaller
sales volume, based on publicly available information, than that of the Company). During 2003, the Company was the largest producer of galvanized (including pre-painted) rolled flat steel in Mexico in terms of production volume (based on information
published by the Cámara Nacional del Hierro y el Acero (the National Chamber for the Iron and Steel Industry or CANACERO) on galvanized steel production during 2003 and on internal sales information). The Company also
believes it is the largest producer of cold-rolled flat steel in Mexico in terms of volume (based on conversations with clients, suppliers and competitors, general knowledge, and the Companys own estimates using information published by
CANACERO on cold-rolled steel production in Mexico during 2003). The Company manufactures and processes steel in three facilities throughout Mexico, as well as five steel service centers, and distributes its products through its fifteen distribution
centers. Outside of Mexico, the Company manufactures and processes steel in four facilities, as well as three service centers, and distributes its products through eleven distribution centers. Additional value-added services are provided by the
steel service centers, such as roll forming, cutting and slitting.



In June 2002, the Company, through IMSA ACERO, acquired certain assets of Pinole Point Steel from Material Sciences Corporation. This acquisition primarily consisted of a galvanized and painted steel plant in Richmond, California, which was
integrated into Steelscapes operations. As of December 31, 2003, the Company had installed capacities of 652,000 tonnes per year for pre-painted flat steel, 1,780,000 tonnes per year for galvanized flat steel (including Galvalume) and
1,750,000tonnes per year for cold-rolled flat steel. Hot-rolled flat steel is primarily used to supply the Companys downstream steel processing operations. By reducing bottlenecks in the production line and adjusting internal
logistics, IMSA ACERO reached a capacity for producing hot-rolled flat steel of 2,200,000 tonnes at the end of 2003. During 2003, the Company had operating income per tonne of Ps 558($50).

Business Strategy



The Companys strategy in the steel processing
products segment is to achieve sustained growth and increased profitability, by processing and distributing low-cost, high-quality processed steel in a variety of value-added sizes, gauges, shapes and surface treatments to the domestic and
international markets, and to maintain its excellent customer service. Key elements of this strategy include:



Expand Presence in International Markets



The Company seeks to maintain a stable base of foreign sales in order to diversify its revenues with respect to both currencies and markets and to be in a
position to capitalize on attractive opportunities in response to changing market conditions. The Company also believes that it is important to maintain foreign sales to maximize capacity utilization in order to respond to economic downturns in the
Mexican economy. In addition, the Company seeks to participate in the high end of the export market by shifting sales to its high value-added products such as galvanized and pre-painted products and cold-rolled flat steel, which face less
competition than commodity-grade steel coils and generate a higher operating income per tonne shipped. In the past, the Company has made acquisitions of production facilities outside Mexico and will continue to analyze new acquisition opportunities.



Further Develop Downstream, Value-Added Products and
Services



The Company plans to expand its value-added
product mix to include a larger percentage of galvanized and pre-painted flat steel, roll-formed steel and specialty cold-rolled flat steel through acquisitions of, investment in and installation of additional steel processing equipment and through
joint ventures. As part of this strategy, during the last five years the Company has increased its cold-rolling capacity by 140,000 tonnes, galvanizing capacity by 445,000 tonnes and painting capacity by 132,000 tonnes. Through these investments,
the Company believes that it will be able to expand its customer base and the range of products it offers to industrial customers in the home appliance, automotive and industrial equipment markets to satisfy the need for specialty flat steel
products. Such industrial market customers provide reliable volume sources and predictable pricing policies.



Continue to Improve Quality and Cost



The Company has invested heavily over the past years to develop technologically advanced hot-rolling, cold-rolling, galvanizing, painting and roll-forming
equipment. The Company intends to continue to make investments in advanced process technology including computer based automated systems. These investments are intended to improve product quality and response time to customer requests, particularly
in the case of the more demanding specifications of industrial customers. See Capital Expenditures below.



Industry Overview



The steel industry is comprised of three different types of entities: primary steel producers, intermediate steel processors and steel service centers.
Primary steel producers historically have emphasized the sale of steel to large



17

##### Table of Contents

volume purchasers. Intermediate steel processors specialize in value-added processing of steel products and play an
important intermediary role between the primary steel producers and the industrial customers, who need processed steel for their manufacturing purposes, and general steel service centers. Steel service centers specialize in the additional processing
of steel to fulfill specific customer demands, such as cutting to length, slitting, shape correction, surface improvement, blanking, plate burning and stamping. The Company is an intermediate steel processor and participates in the steel service
center industry in Mexico, the United States and Central America.



Primary steel production is a capital-intensive process characterized by high fixed costs. Intermediate steel processors generally have more flexible cost structures, including lower labor costs, inventory levels and capital investment per
tonne produced, than primary steel producers.



Steel processors
occupy a niche in the steel industry by focusing on more specialized products requiring more exact specifications and more intensive service. As a steel processor, the Company buys steel slabs and coils of wide, open tolerance steel from major
integrated steel mills and mini-mills and processes the steel to the precise type, coating, thickness, length, width, shape, temper and surface quality specified by its customers.



Products



The Companys steel processing products currently include galvanized flat steel products and pre-painted flat steel products, galvanized steel
shapes, cold-rolled flat steel (full hard and annealed and tempered), hot-rolled coils and pickled and oiled hot-rolled coils. Since 1997, coated steel and non-coated steel have each accounted for roughly one-half of the Companys total steel
production by volume. The bulk of the non-coated steel produced since 1997 has been sold domestically. As a result of the acquisition of Steelscape in 2000, more than half of coated steel products are now sold outside Mexico.



The following table sets forth the Companys total sales of steel
processing products for the period indicated.

Galvanized Flat
Steel



The Company believes that, during 2003, it was the
largest galvanized flat steel producer in Mexico in terms of production volume, including Galvalume steel products which are marketed under the brand name Zintro-AlumTM(based on information published by CANACERO on galvanized sheet production during 2003 and on internal sales information). Galvalume products are considered to have a high-quality
metallic facing because they use a zinc-aluminum-silica alloy coating, which lasts longer and is more resistant to corrosion than normal zinc galvanized steel. The principal domestic and foreign end-users of galvanized flat steel products are the
construction, automotive and home appliance manufacturing industries. In particular, the construction market in Mexico is served mainly through in-house fabrication and distribution of different roll formed steel components. The Company markets
unpainted zinc galvanized flat steel under the brand name ZintroTM. In addition to its activities in Mexico
through IMSA-MEX, the Company also produces and markets galvanized steel products through Steelscape in the United States and through Industria Galvanizadora in Central America.



Pre-painted Flat Steel



The Company believes it is currently the largest producer of pre-painted flat steel in Mexico in terms of sales volume (based on conversations with
clients, suppliers and competitors, general knowledge, and the Companys own estimates using information published by CANACERO on galvanized sheet production in Mexico during 2003). The Company produces and markets pre-painted zinc-galvanized
and Galvalume flat steel under the brand names PintroTMand Pintro-AlumTM, respectively, in a variety of colors which, in addition to enhancing the corrosion
resistance, adds to the attractiveness of the product. The principal domestic and foreign end-users of pre-painted flat steel are roll formers, prefabricated building product manufacturers, appliance manufacturers and the automotive industry. In
addition to its activities in Mexico through IMSA-MEX, the Company also produces and markets pre-painted steel products through Steelscape in the United States.

Galvanized Steel Shapes



Galvanized steel shapes consist of several galvanized steel products for the construction market, including galvanized steel
profiles, which are used in the manufacture of wall studs, purlins, tubes and other shapes, window and door frames, fences, grating and structural members. The Company produces galvanized steel shapes in Mexico through IMSA-MEX and in Central
America through Industria Galvanizadora. All of these steel shapes are fabricated at the Companys steel service centers from its internally produced galvanized sheet steel. At steel service centers, flat galvanized steel may be cut and slit to
specific lengths and widths, as well as corrugated in roll-forming machines to produce corrugated deck and roof panels for composite reinforced concrete construction or corrugated roofing panels for rural applications or low income housing.



Cold-Rolled Flat Steel (Full Hard and Annealed and
Tempered)



The Companys cold-rolling mills
manufacture high-grade products with accurate gauge control, surface quality and ductility that meet the demands of end-users. The Company uses a hydrogen-nitrogen atmosphere in most of its annealing ovens to obtain the high surface cleanliness of
the annealed product required for certain applications. The Company produces cold-rolled flat steel in both Mexico and the United States. Domestic and foreign end-users of cold-rolled flat steel include tube makers, steel roll formers and
manufacturers of automotive parts, appliances, machinery and equipment, steel strapping and coated steel.



Hot-Rolled Coils and Hot-Rolled Pickled and Oiled Steel



The Company purchases steel slabs to produce hot-rolled coils, generally ranging from 0.075 inches to 0.625 inches in thickness. Most of the
Companys production of hot-rolled steel serves as feedstock for the Companys cold-rolling operations. The Companys hot-rolling capability enables it to control the quality of the raw material used in its downstream steel processing
operations. By purchasing high quality steel slabs and processing such slabs with process control technology in its hot-rolling mill, such as coil box technology, the Company produces higher quality hot-rolled feedstock with consistent mechanical
characteristics. The Company produces hot-rolled coils and hot-rolled pickled and oiled coils in Mexico and is capable of producing these hot-rolled coils and hot-rolled pickled and oiled coils up to 60 inches wide.



Manufacturing Process



In hot-rolling, a steel slab approximately eight inches thick is heated in a
reheating furnace. Its thickness is then reduced through compression rollers in a reversing mill (a roughing mill) until it is sufficiently thin to permit coiling. The hot coil is then further processed through a series of tandem-mounted finishing
rolling stands until the desired thickness is reached. Cooling of the steel coil during this process often leads to thickness variations and non-uniformity of mechanical properties between the beginning and the end of the coil. The Company employs
coil box technology, which uses a heated enclosure to keep the temperature of the hot coil constant as it enters the tandem mill, resulting in more uniform thickness and mechanical properties. Hot-rolled steel is relatively soft and has a high
degree of ductility. For certain applications requiring a cleaner surface, or if the steel is to be cold-rolled, the steel is pickled by uncoiling the strip and dipping it into an acid bath, which removes surface oxidation and other
impurities, followed by a rinse and light oil spray, before being coiled again.



Cold-rolled flat steel is produced by processing hot-rolled pickled and oiled steel, without reheating, through a series of compression reduction rollers, which results in more precise tolerances and enhanced surface
characteristics. Cold-rolled flat steel is considerably harder but much less ductile than hot-rolled steel. Cold-rolled flat steel coils may be utilized directly after cold-rolling (full hard) for galvanizing and certain other applications, but most
often such coils are annealed by reheating in an annealing oven to restore ductility and then tempered through controlled rapid cooling to restore elasticity and some of the hardness lost through the annealing process. For applications requiring a
high degree of flatness, the strip is then processed through a tension leveler in which the strip is passed through rollers and slightly deformed under tension to produce a curvature opposite from the curvature of the coil, resulting in a steel
strip that is nearly flat after uncoiling.



The Company
produces galvanized steel in a continuous process using technologically advanced equipment. Galvanized steel is produced by subjecting a cold-rolled flat steel strip to a surface cleaning process and then, after

preheating, immersing it in a molten zinc bath, thereby obtaining a corrosion-resistant surface coating. Galvalume steel
is produced in the same manner as zinc galvanized steel, but using a molten zinc-aluminum alloy coating. Pre-painted flat steel is obtained by processing coils of galvanized flat steel through a set of roller coaters and ovens which continuously
apply and cure a uniform layer of paint or vinyl on each side of the strips.



The Companys quality assurance program begins with the identification and certification of reliable suppliers for raw materials and continues with the systematic quality-control testing of incoming raw
materials, integral process control in the production lines and visual inspections and tests of material properties at the various process stages and at the end of the production process to verify the quality of the final products. The
Companys use of advanced process control technology and information systems in its steel processing operations has resulted in productivity gains and increased reliability for satisfying the stricter specifications of industrial customers. The
Company has obtained ISO-9002 certification with respect to the quality assurance programs at certain of its steel processing facilities. In 2004, IMSA ACERO utilized a 6-Sigma program to obtain additional benefits in cost reduction and quality
improvement.



Sales, Marketing and Distribution



The Company sells its steel processing products
domestically and internationally to industrial, construction and commercial customers. In 2003, the Company exported its products to 23 countries. The following table sets forth the domestic and export sales of steel processing products for the
periods indicated:

Domestic Sales



Domestic sales of the Companys steel processing
products are made through its distribution network throughout Mexico that includes 15 distribution centers (five of which are also steel service centers). The Companys distribution centers facilitate access to its products in the market by
also stocking standard products. In addition to sales personnel, the distribution centers have administrative and customer service staff and information systems to process customer orders, perform credit verification and approval, carry out
invoicing and collection functions and act as customer liaisons. The Company believes that the continuous interaction between its sales force and its customers provides it with valuable market information and sales opportunities. In 2003, the
Companys steel service centers accounted for approximately 75% of the domestic sales of its coated-steel products, which were made to approximately 2,467 customers.

Domestic customers are
divided into three principal classifications: industrial customers, construction contractors and commercial distributors. Industrial customers convert flat steel into other products and include manufacturers of appliances, automotive parts,
transportation and recreational vehicles, commercial refrigeration equipment, heating, ventilation and air conditioning ducts and equipment and other products. Industrial customers purchase high-specification steel products for quality-critical
pre-painted flat and corrugated sheets, slit and cut to length; galvanized roll-formed sheets, slit and cut to length; and galvanized light shapes. Construction contractors produce and install steel components in construction projects and include
general

##### Table of Contents

construction contractors, metal building contractors and metal specialty contractors. Construction contractors purchase
primarily pre-painted roll-formed sheets and shapes and galvanized roll-formed sheets and shapes. Distributors, which include steel service centers and construction materials dealers, resell at the retail level to smaller customers and those seeking
credit, delivery or other terms not available directly from the Company. Distributors primarily purchase galvanized corrugated sheets and galvanized light shapes from the Company.



The Company emphasizes customer service and satisfaction, overseeing handling, shipping and follow-through with respect to
client orders to ensure that the customers expectations are satisfied and that product rejections are minimized. The Company advises certain domestic customers with respect to management of their inventories and maintains
just-in-time delivery arrangements with several of its industrial customers. The Company has long-established relationships that have resulted in close cooperation between the Company and many of its industrial customers. Although the
Company ships steel processing products by truck throughout Mexico, many of its industrial and steel processor customers are located in the Monterrey area and therefore are in close proximity to the Companys steel processing plants.



With respect to certain industrial customers that use flat
steel in the manufacture of export products, the Company transacts domestic sales of flat steel products in dollars and accepts payment in pesos at the prevailing exchange rate on the date payment is made. Although the Company generally does not
enter into long-term, fixed-price contracts for its steel processing products, industrial customers provide reliable volume sources and predictable pricing policies. Certain volume discounts from list prices are available.



Export and Foreign Company Sales



The distribution of the Companys exports among the various
geographical markets fluctuates depending upon the attractiveness of the prices in the respective markets from time to time. Export sales consist of sales through traders and direct sales (not including foreign subsidiary sales). In the United
States, the Company has developed strong commercial relationships with direct customers through a U.S.-based sales and distribution organization which provides those customers with continuous coordination and close contact in terms of product
offering, logistics, credit and technical service. In Central America, the Company has developed a distribution network through the establishment of distribution centers in the same manner as in Mexico.



The table below sets forth the Companys exports of steel processing
products by geographical market for the periods indicated.

Traditionally, the
Companys principal export market has been the United States. However, the Company also exports to countries in Latin America and to other countries. Exports to the United States serve the commercial, industrial and construction markets.
Exports to Latin America primarily serve the industrial and construction markets. The principal export customers in the United States are steel service centers, as well as metal building contractors and manufacturers of building components, mobile
homes, heating, ventilation and air conditioning ducts and equipment and other products.



The Company not only exports steel to the United States from Mexico, but since 2000, most of its steel products are marketed from its three production plants on the West Coast of the United States. This is a result of
the acquisition of Steelscape in June 2000 and the Pinole plant in 2002, which mainly serve the construction industry with galvanized and painted steel.



The Company is pursuing additional export opportunities for its products in the United States, South America and elsewhere. In addition to galvanized
steel, the Company is focusing on the export of niche products, particularly pre-painted products. See Business Strategy below.

Competition



Critical factors in maintaining a competitive position in the Mexican steel processing industry are cost reductions through
productivity gains and the use of technologically modern equipment, dependable sources of raw materials and developed domestic and export distribution systems. Additionally, specific competitive factors vary by type of customer. In the industrial
market, key factors include consistent quality of products, complete and timely deliveries, and customer service, including product development and technical assistance. In the construction market, key factors include a wide range of products for
construction applications, product performance and timely deliveries. In the commercial market, key factors include competitive pricing, product availability from inventory and ongoing sales and marketing efforts.



The Companys principal domestic competitors in the galvanized flat
steel market are Galvak, S.A. de C.V. (Galvak), a subsidiary of Hylsamex, and Zincacero, S.A. de C.V. (Zincacero), a part of the Villacero Group, as well as specialized imports. The competition from Galvak, Zincacero and
imports has resulted and will continue to result in some pressure on galvanized flat steel prices. However, the Company believes this is offset by its competitive strengths including: (a) its nationwide distribution network, (b) its high-quality raw
materials resulting from its supply strategy, (c) its technologically advanced processes, (d) its reliable customer service and (e) its new product development expertise and capabilities.



Competition in the domestic hot-rolled and cold-rolled markets comes primarily from Hylsamex and AHMSA. Key competitive
factors in these markets include price, product quality and service. The Company believes it has a competitive advantage in cold-rolled product quality because of its advanced technology and leading edge facilities; and because its hydrogen-nitrogen
atmosphere annealing ovens enable it to produce cold-rolled flat steel coils with consistent mechanical characteristics and a cleaner surface. At the same time, its efficient, technologically advanced production processes enable it to maintain a
competitive price.



In addition to domestic competition, the
Company traditionally has competed with imports based on price and, more recently, on quality and service. The Company believes that it offers a higher level of service than foreign producers by allowing customers to place smaller orders, lowering
customer response time, permitting greater flexibility in changes to customer orders and providing faster settlement of claims and assurance of supply.



The Company believes that NAFTA has resulted in a larger market for the Companys steel products as many production facilities have been established
in Mexico and as foreign direct investment has required steel for new construction. Although the Company does not believe NAFTA has materially affected competition to date, free trade resulted in price pressures for some products. The Company
competes for international sales with many domestic and foreign steel processors, none of which dominate or exert any significant influence on the international markets served by the Company. The Company believes it is competitive in international
markets based on the prices and quality of its products.



The
main competitors of Steelscape are California Steel Industries, Inc. and USS-POSCO Industries. Steelscape is the Companys subsidiary on the West Coast of the United States.



The Company is not currently subject to anti-dumping or countervailing duties or deposit requirements in the United States,
and the Company is not aware of any countervailing or anti-dumping duties leveled against the Companys products that could result in a potential obstacle to their access to the United States, Canadian or Latin American markets. Recently, the
ITC preliminarily determined that dumping with respect to standard and line pipes from Mexico had occurred, and, as a result, imposed an anti-dumping tariff of 11% on Mexican companies that export these products to the United States. Because of this
preliminary determination, the Company has ceased exportation of these products to the United States. See Item 3. Key InformationRisk FactorsRisks Relating to Competition for further discussion regarding anti-dumping claims
and tariffs.



Production Facilities



The Company operates production facilities and service centers in Mexico,
the United States and Central America. The Company has one hot-rolling strip mill, four cold-rolling mills, four pickling lines, three surface-cleaning lines, two tension-leveling lines, nine galvanizing lines, six painting lines, 43 annealing
furnaces and 25 rolling lines. See Description of Property below.

Research and Development



The
Companys research and development department has established a successful record in the development of new products for the appliance, electrical machinery, construction and transportation vehicle industries and others. Successful projects
include the development of mechanical characteristics, appearance, finishes, processability, environmental resistance features and other design characteristics for specific industrial applications. The research and development department also
periodically recommends implementation of process or equipment modifications in an effort to improve quality and productivity.



The Company maintains a team of technical advisors within its product engineering department to keep abreast of relevant technological developments in the
steel industry and to work closely with customers in the development of new products. A major focus of this team is seeking new applications integrating the Companys products into its industrial customers products and takes place at such
customers production facilities.



The Company
periodically sponsors research projects at Mexican universities. In addition, members of the research and development department are active in the technical committees of international associations relevant to the Companys products.



Capital Expenditures



The Company has recently completed a series of major capital expenditures in
the steel processing products segment to modernize facilities, expand production capacity, vertically integrate its operations and improve operating efficiency.



In 2003, the Company, through IMSA ACERO, completed the expansion of its hot-rolled steel production capacity, increasing its capacity to 2.2 million
tonnes per year. The upgrade of the mill enables IMSA ACEROto offer a wider range of resistance and caliber specifications to existing customers and to expand its customer base. Moreover, the additional production capacity positions the
Company to capture growth in Mexico and increase exports. This expansion was complemented by the opening of a modern logistics center which enhances the efficiency of finished product shipping. In the United States, IMSA ACERO began operating a new
cut-to-length line at its plant in Kalama, Washington, to serve the rainwater accessories for residential construction segment. INGASA, IMSA ACEROs business in Central America, inaugurated its second steel galvanizing line in Guatemala,
increasing annual production capacity from 70 thousand to 120 thousand tonnes. This investment allows INGASA to offer a wider range of galvanized steel products and profiles, improves its coverage in Central America, and positions it to increase
exports to the United States, the Caribbean and South America. Additionally, a new service center was set up in Puerto Rico to support the strategy of increasing the Companys presence in Central America and the Caribbean.



Raw Materials and Supplies



The Companys principal raw materials for the manufacture of its steel
processing products are slabs of steel, hot-and cold-rolled flat steel coils, zinc and zinc-aluminum alloy ingots. The Company purchases slabs of high-quality steel from major domestic and international steel mills at regular intervals, either in
the spot market or pursuant to non-binding purchase agreements. The Company obtains competitive pricing by purchasing steel slabs in large quantities that are efficient for the steel producers. The Company purchases steel slabs from Ispat Mexicana,
S.A. de C.V. (Imexa) in Mexico, Companhia Siderúrgica de Tubarão, Companhia Siderúrgica Paulista, and Companhia Siderúrgica Nacional each in Brazil, and Siderúrgica del Orinoco, C.A. in Venezuela and
Novo Lipetsk Met Kombinat in Russia, as well as from other slab producers around the world. The Companys five-year agreement with Imexa to supply 75% of its slab requirements will terminate in August 2004.

Although a large portion of the Companys requirements of hot- and cold-rolled flat steel is
produced internally, the Company purchases hot- and cold-rolled flat steel coils from AHMSA and several foreign suppliers in the spot market. The Companys U.S. and Central American facilities purchase steel from several foreign suppliers.
Prices of hot and cold-rolled sheet steel fluctuate with international prices.



Automotive Batteries and Related Products



General



In December 1998, the Company,
Johnson Controls and Varta formalized an agreement to form three joint ventures to manufacture and distribute automotive batteries in the American Continent. The Company and Johnson Controls partnered to form a joint venture in Mexico to serve the
Mexican market and to export batteries to the United States, Canada and Central America. The Company and Johnson Controls also became partners in GES Battery Systems (formerly GES America), which is a sales and marketing network that serves medium
and small clients in the United States and Canada. The Company, Johnson Controls and Varta partnered to form a joint venture in South America to manufacture and distribute automotive batteries in that region.In October 2002, Johnson Controls
acquired Vartas Automotive Battery Division.



The joint
ventures expanded the partners global manufacturing, marketing and distribution capabilities to better serve original equipment and aftermarket automotive battery customers. The production capacity of the joint ventures in Latin America is
believed to be the largest in the region (based on the Companys market share analysis in major Latin American countries which shows that only one competitor operates in different regions of Latin America and that the Company exported 12.7
million batteries in 2003 to non-Latin American countries).



The Company believes that it is the largest automotive starting, lighting and ignition (SLI) battery producer in Mexico (based on market share analysis performed at the Companys expense by Melgar y Asociados in Mexico; and
information published by the Instituto Nacional de Estadística, Geografía e Informática, the Asociación Mexicana de la Industria Automotriz(AMIA), the Asociación Nacional de
Productores de Autobuses, Camiones y TractocamionesandIndustria Nacional de Autopartes, which was used by the Company to estimate the automotive battery market size and the Companys market share), with an annual production
capacity of 22.5 million units and a market share in the Mexican replacement market of approximately 72% in 2003. Approximately 83% of the Companys automotive batteries for sale in Mexico are sold to the replacement market, which historically
has been subject to substantially less cyclicality than the Original Equipment Manufacturer, or OEM, market. The Companys automotive battery products include the LTHTMbrand, which has been in production since 1928. In Mexico, over 90% of the Companys battery products are delivered by its fleet, which also collects and
transports exhausted batteries for recycling.



The following
table sets forth the net sales and operating income of the automotive batteries and related products segment for the periods indicated, as well as the assets of the segment at the end of each period, together with the respective percentages of the
Companys consolidated net sales, total operating income and total assets for, and at the end of, each such period.

##### Table of Contents

expansion strategy in Latin America, which will allow the Company to participate in the consolidation taking place in the
Mercosur market (composed of Argentina, Brazil, Paraguay and Uruguay) and the Andean region. The key elements of this strategy include:



Continue International Expansion Program



The joint venture with Johnson Controls, established in December 1998, has allowed the Company to expand its presence in North America. The Company
believes that Johnson Controls is the leading SLI battery corporation in the North American market (based on information published by Johnson Controls) and has strengthened the position of the joint venture established in Mexico to export to the
U.S. market. The Company intends to capitalize on its successful entry into the North American market, where the Company has registered annual growth in terms of sales volume in each of the last 12 years.



The Company believes that the South American markets are very attractive in
terms of their size, expected growth of vehicle population, fragmented industry structure, low level of vertical integration and increased growth of new vehicle assembly. Through the joint venture established with Johnson Controls in South America,
the Company now has a production capacity of 5.0 million units per year in Brazil. The Company also seeks to leverage its relationships in the OEM market as well as its relationship with Asian and European manufacturers located in North America.



Emphasize Efficiency and Lower Costs



The Company believes it is currently the lowest-cost producer of automotive
batteries in the Mexican market (based on its economies of scale, its level of automation and its lead and polypropylene recycling processes). In 2003, the Companys battery recycling program, including the recovery of exhausted batteries
through its distribution network, provided approximately 46% of the lead and 36% of the plastic requirements used in its manufacturing operations in Mexico. See Raw Materials and Suppliers below. In addition, the Company has
consolidated its manufacturing operations in the Mercosur and Andean regions in order to achieve manufacturing economies of scale and increase capacity utilization, which the Company believes will result in lower fixed costs per unit.



In order to reduce costs and increase productivity, ENERMEX has focused on
three continuous improvement initiatives: 6-Sigma, Stake in the Ground (SITG) and Innovation. ENERMEX has personnel who dedicate 100% of their time to the application of statistical methods to reduce process variance (Black Belts) as
well as employees who spend part of their time applying such methods (Green Belts). In 2003, Black Belts were involved in 199 projects and Green Belts were involved in 72 projects. SITG is a methodology that guarantees that planned
activities are completed and their benefits achieved by predetermined deadlines. ENERMEX used SITG in 172 projects and implemented 10,207 ideas that resulted from the process of Innovation, in which union and non-union workers participate by sharing
their ideas and suggestions for improvement. The 2003 continuous improvement projects resulted in, among other things, a 14% increase in batteries produced per man-hour, a significant reduction in the cost of production per battery, lower
distribution and sales expenses and a decline in past-due accounts.



Global Customer Accounts



There is a trend
among automotive battery buyers to increase the purchasing of batteries through global sourcing. OEMs are joining their total global requirements and asking suppliers to deliver the same product, at the same price, anywhere in the world where they
have facilities. In the replacement market, major retailers are beginning to do the same. The joint ventures with Johnson Controls enables the Company to participate in these programs as its partner complements the Companys manufacturing
facilities in the United States, Europe and Asia. The Company foresees an increase in global sourcing, which will continue to enhance its competitive advantage over local manufacturers.

Automotive SLI
Batteries



An Automotive SLI (lead-acid) battery is a low
voltage electrical storage device that uses a reversible chemical reaction to store energy. It uses a combination of lead plates, composed of lead grids and oxide immersed in diluted sulphuric acid and sealed in a plastic container and cover.
Batteries are initially activated under controlled charging conditions to establish the chemical properties necessary to convert electrical energy into potential chemical energy and back again. Batteries are built for different market applications
(cars, trucks, boats, golf carts, etc.) and they differ in construction accordingly. Different plate, alloy formulas and process conditions are used to allow for optimum performance in a variety of weather and operating conditions.



Battery covers and containers are made of injection-molded plastic
components. The Company provides for a significant portion of its own plastic components needs, and obtains a significant portion of the raw material from its battery recycling operations.



The Company sells automotive batteries to independent distributors for the
replacement market in Mexico, Brazil, Venezuela, Colombia and Argentina, and exports automotive batteries to several other countries in Central and South America. Exports to the United States are made through Johnson Controls and GES Battery
Systems. The Company sells automotive SLI batteries to OEMs in Mexico, Argentina and Brazil for installation in new cars, trucks, tractors and farm equipment. In addition to the Companys own brands, the Company manufactures private label
batteries for sale in Mexico, the United States, Central and South America.



The Company manufactures and markets complete lines of lead-acid automotive SLI batteries under the LTH, Cronos, Full Power, Hi-Tec 30, Diener and America brand names in the Mexican market.



The Company distributes its batteries in Venezuela under the Fulgor, Varta and Bestia Negra brand names and in Puerto Rico under the Everlite brand name. The Companys batteries are distributed in Argentina under the Prestolite,
Varta, Nationwide, and Heliar brand names and in Brazil under the Heliar, PowerFree and Durex brand names.

Domestic Sales



In 2003, the Companys domestic sales in the replacement market and the OEM market were 83% and 17%, respectively,
based on volume. The replacement market is affected by the age and number of vehicles in service more than by new vehicle production levels and tends to be less cyclical than the OEM market. The principal domestic customers include wholesale
distributors, large retailers, mass merchandisers and large fleets. Wholesale distributors sell directly to retail customers, repair shops and institutional customers. Distributors sell to retailers and to institutional customers. Retailers consist
primarily of automotive parts stores that carry a broad line of automotive products. The Company operates a truck fleet to deliver products from its distribution centers to its customers. The truck fleet also serves as part of the exhausted battery
collection system for its battery recycling operations.



The
Company sells directly and works closely with its OEM customers, which enables the Company to develop new models to meet varying requirements. OEM battery sales are closely linked to new vehicle sales.



Export and Foreign Company Sales



The Companys principal export markets for automotive batteries
historically have been the United States and Canada. Exports are sold to Johnson Controls, which resells the batteries to major retailers in the United States, and to GES Battery Systems, which sells to battery specialists, independent auto parts
stores, fleet operators and parts distributors.



The
Companys foreign company battery sales are made through independent battery wholesalers. In Brazil, four sales branches serve approximately 627 accounts. In Venezuela, one sales branch serves approximately 30 accounts.



Competition



The replacement and OEM battery markets served by the Company are highly
competitive. The principal factors of such competition in the replacement market are price, quality, service, warranty and delivery time. In the OEM market, competition is also based on technology and global sourcing capabilities.



Competitors in Mexico include domestic producers such as Acumuladores Cale de
Tlaxcala, S.A. de C.V. and Gonher de Mexico, S.A. de C.V. Imports are made in small quantities and to specific regions from major multinational competitors such as Exide Corporation, Delphi and other regional manufacturers in the United States.
Competitors in South America include Acumuladores Moura S.A., Acumuladores Titan, C.A., Willard/Wao, Champion, S.A., Pradema, MAC de Colombia, Delphi Automotive Systems Brazil, Acumuladores Duncan, C.A., Industria Tudor SP de Baterias, Acumuladores
Ajax and Baterias Cral.



The Company believes its
automotive batteries have a competitive advantage in Mexico due to the Companys vertical integration, its distribution network and its brand recognition. An important part of the Companys vertical integration is its recycling
capabilities which enable the Company to collect and recycle much of the lead and plastic that are used as raw materials. As a result of lead recycling, the Company believes that its lead costs are lower than current international lead prices. See
Raw Materials and Suppliers below.



As a
result of NAFTA, import duties were gradually reduced, until completely eliminated in 2003; therefore, the Company expects to face marginal increases in competition in Mexico from U.S. producers of automotive batteries. However, the Company believes
that entry costs for potential competitors are high because of the need to develop brand recognition and significant distribution capabilities. Accordingly, the Company believes that it can maintain its current domestic market share, in terms of
battery sales, by maintaining and improving the quality of service to its distributors and by developing advanced battery technology through its research and development activities and technical assistance provided by Johnson Controls.



Production Facilities



The Company operates four automotive battery manufacturing plants in Mexico,
two of which are located in the Monterrey area, one in Torreon and one in Celaya. In October 2002, ENERMEX closed the Enertec Mexico plant in Tlaxcala, because its northern Mexican plants in Monterrey, Escobedo and Torreon are better located for
exporting to the United States and its Celaya plant offers proximity as well as the original equipment certifications required by ENERMEX customers. ENERMEXs production capacity was unaffected by the closure of its Tlaxcala plant because the
Companys other plants absorbed that production. The Company also has a battery plastic components manufacturing

plant and one exhausted battery recycling plant located in the Monterrey metropolitan area. The Companys foreign
facility consists of one automotive battery manufacturing plant, located in Brazil. In Mexico, the Company extensively recycles automotive batteries and operates one recycling facility with an output capacity of approximately 97,000 tonnes of lead
and 9,200 tonnes of polypropylene per year. See The CompanyDescription of Property below. The Company has developed, and converted its recycling facilities to, a proprietary lead recovery and smelting process which enhances lead
recovery and produces waste by-products which are classified as non-hazardous materials for purposes of disposal (Green Slag). The process, which was installed by the end of 1997, generated a reduction in recycling costs and improved the quality of
recovered lead.



The following table sets forth the installed
capacities and percentage utilization for the automotive batteries and related products segment facilities for the periods indicated.

Research and Development



As part of the joint venture, Johnson Controls provides technical assistance and technology to the Company. Access to Johnson Controls technology is
considered by the Company to be one of its competitive advantages. In Mexico and South America, cost reduction opportunities, both in product and processes, as well as access to future trends in battery manufacturing, are producing substantial
benefits in quality and profitability.



Capital
Expenditures



In prior years, the Company completed
several significant capital expenditure projects related to the automotive batteries and related products segment. ENERMEX concentrated its 2003 capital expenditures on increasing the productivity of its operations and finishing a macro-distribution
center. Old production lines are being continuously replaced with higher efficiency state-of-the-art lines and in 2003, the new macro-distribution center began operating in Celaya, Guanajuato, to supply all of Mexico.



Raw Materials and Suppliers



The Companys principal raw materials for the manufacture of its
automotive and industrial batteries are lead, polypropylene, sulfuric acid, calcium and antimony, all of which are generally available in the open market from multiple sources. Lead represented approximately 63% of the raw material cost of the
automotive batteries segment for the Companys plants operating in Mexico and approximately 50% of the total cost of sales for the year ended December 31, 2003. The Companys battery recycling program, including its recovery of exhausted
batteries through its distribution network, provided approximately 46% of the lead and 36% of the plastic requirements used in its manufacturing operations in Mexico for the year ended December 31, 2003. In addition to its own exhausted battery
recovery, the Company imports exhausted batteries for recycling from the United States. The Company principally acquires its lead from two sources: through its recycling facility and in the open market. Because the lead produced by the Company in
its recycling facility is not subject to open market price fluctuations, the Company determines prices based on commercial strategy without the use of price adjustment mechanisms with respect to the sale of batteries which use this recycled lead. On
the other hand, because the lead acquired by the Company in the open market is subject to volatility, the Company enters into contracts that adjust for and take into account this volatility with respect to the sale of batteries which use this new
lead.

Steel and Plastic Construction Products



General



The Companys steel and plastic construction products business evolved out of the Companys steel processing business as a value-added extension
of the Companys galvanized and pre-painted flat steel product lines. The activities of the segment have expanded over the years to encompass the manufacture and sale of a broad range of steel and plastic fabricated products for use in the
construction and other industries. The Company believes that its metal processing and fabrication expertise, product development capabilities and ability to identify and pursue strategic acquisitions have been instrumental in the expansion of its
steel and plastic construction products segment. The Company believes that it is one of the largest pre-engineered metal building companies (based on reports of the Metal Building Manufacturers Association), producers of prefabricated steel and
foam-insulated panels (based on information available from the Foam Panel Council of the Metal Construction Association and the Companys internal data) and FRP panels (based on the Companys general knowledge of the FRP panels market, as
well as information gathered from suppliers, clients and competitors) in North America in terms of sales volume. In addition to its Mexican operations, the steel and plastic construction products segment includes operations in the United States,
Chile and Spain. The United States historically has been the Companys principal export market for the steel and plastic construction products.



The following table sets forth the net sales and operating income of the steel and plastic construction products segment for the periods indicated, as

Business
Strategy



The Companys business strategy in the
steel and plastic construction products segment is to take advantage of growth opportunities in the construction sector and home improvement markets through the manufacture of a diversified portfolio of fabricated steel and plastic construction
products. The principal elements of the Companys strategy are:



Pursue Additional Opportunities in Manufactured Products



Consistent with its overall strategy of downstream integration to allow the realization of higher margins for its steel products, the Company intends to continue seeking strategic opportunities to produce finished
products. The Company draws on its manufacturing and distribution experience to pursue further growth opportunities in new markets that the Company services.



The steel and plastic construction products segment has been built primarily through acquisitions and joint ventures. See History and
Development of the Company above. The Company has demonstrated over the years the ability to identify, acquire and assimilate complementary companies. The Company will continue to make acquisitions where it believes its ownership and
operations will enhance the value of the acquired companies. In addition, the Company will continue to seek strategic alliances with international partners that can contribute new technologies for products to be manufactured and distributed through
the Companys operations in Mexico or internationally distributed through its partners network.



Coordinate Overlapping Markets and Distribution Channels



The Company believes there are growth opportunities provided by overlapping markets in the Companys markets and distribution channels for certain
steel and plastic construction products. The Company strives to take advantage of such opportunities by increasing customer awareness of the range of its products.

New Product Development



The Company continuously works toward the development of new products to extend both its client base and the applications
for which its products may be used. The Company believes that by providing innovative solutions to its clients, it can generate competive advantages in its markets.



Emphasize Customer Service



The Company believes customer service is a crucial element of its growth strategy. As part of its continuing customer service activities, the Company
engages in vendor-managed inventory activities with some of its customers. The Company has also established retail link information systems with several mass merchandisers in the United States to enable the Company to respond more
efficiently to its customers orders. The Company supports these activities with flexible manufacturing capabilities in order to meet its customers varying demands.



Products



The steel and plastic construction products segment is comprised of steel and plastic construction products, consisting of prefabricated steel and
foam-insulated panels, FRP panels, galvanized steel products (including culverts, guardrails, electric transmission towers and lighting stands), steel and plastic packaging products, pre-engineered metal buildings and steel building products for
roofing, siding and deck.



Prefabricated Steel and
Foam-Insulated Panels



Prefabricated steel and
foam-insulated panels consist of a closed-cell polystyrene or polyurethane foam glued or injected, as the case may be, between steel sheets. The primary raw material used in the production process for prefabricated steel and foam-insulated panels is
pre-painted flat steel, which is partially supplied by the Companys steel processing products segment. These panels are used in prefabricated buildings; in certain exterior architectural applications, such as storefronts, roofs, canopies,
cornices and telephone and vending booths; in interior architectural applications, such as walls; and in industrial applications such as insulating walls, roofs and doors for cold storage chambers. Insulated panels for certain applications requiring
rigid insulation but not involving exterior exposure are manufactured using polyurethane foam between tar paper sheets. The Company believes it is currently the largest producer of prefabricated steel and foam-insulated panels in Mexico in terms of
sales volume (based on information gathered by the Company from certain of its new contracts).



FRP Panels



The Company manufactures translucent and opaque FRP panels (out of polyester and acrylic resins), in both flat and corrugated varieties, for the
construction industry. The panels are made from mixing resins and catalysts with fiberglass and applying the mixture on a carrier film in a continuous casting process. Applications include roofs, greenhouses, patio sheds and skylights, partitions,
wall protection coverings and other applications. As a result of the joint venture with Bayer AG, the Company started to produce double wall polycarbonate sheet in 2001. This product is the equivalent of a high-end FRP panel.



Galvanized Steel Products



The Company manufactures a variety of fabricated galvanized steel products
for the construction industry, including culverts, guardrails, electric transmission towers, steel poles, lighting stands, corrugated pipe for water drainage and sewers and galvanized steel fence posts. Such products are made by processing steel
into the desired shapes and galvanizing the formed product through a hot-dipped batch process.



Steel and Plastic Packaging Products



The Company manufactures steel packaging products consisting of steel strapping and other similar products used in handling and packaging industrial shipments. The Company also manufactures plastic strapping and
distributes plastic industrial packaging products such as adhesive tape and packaging film for other packaging applications. The Company has a joint venture with ITW managed by its Signode Division, which the Company believes is one of the
worlds largest manufacturers of steel and plastic strappings (based on information published by ITW).

Domestic Sales



In general, distribution of steel and plastic
construction products is made through three distribution channels: direct sales, sales to distributors and retail sales. Direct sales to major industrial or institutional customers (including government agencies) are generally shipped from the
manufacturing plant. Sales to retailers or independent distributors are normally processed through the manufacturing plant or Company-owned distribution centers that also function as branch sales offices.



Export and Foreign Company Sales



The United States historically has been the Companys principal foreign
company sales and export market for steel and plastic construction products. Exports to the United States and Canada consist primarily of FRP panels and, in coordination with ITW, steel and plastic strapping. While the United States continues to be
the most important foreign market for the steel and plastic construction products segment in terms of volume, the company also has sales to non-U.S. customers. Exports to Central and South America consist primarily of FRP panels and prefabricated
steel and foam-insulated panels. Foreign company sales include pre-engineered metal buildings, steel building products for roofing, siding and decks, prefabricated steel and foam-insulated panels and FRP panels manufactured in the United States, FRP
panels manufactured in Spain and prefabricated steel and foam-insulated panels and steel products for highway construction manufactured in Chile.



The Company distributes the products it exports through independent sales representatives who sell to distributors and through the distribution systems
established by its strategic partners, such as ITW. Certain large institutional accounts are serviced directly by regional sales managers. The Company distributes its products manufactured by foreign companies through Company and independent sales
representatives.

In the steel and plastic construction products segment, the Company plans to undertake several capital expenditure projects intended to modernize
facilities, reduce costs, improve production quality and increase capacity. In 2003 IMSATEC, through Imsa Signode, concluded the consolidation of equipment from two facilities into a new, modern plant, capitalizing on this change to update its
production and install a new line for processing polyester strapping. To expand the geographical coverage of its services in the United States, VP Holdings focused capital expenditures on adding new processes to existing facilities, thereby
increasing the range of products that may be manufactured at each location.



Raw Materials and Suppliers



The steel and plastic construction products segment uses raw materials consisting of hot-rolled, cold-rolled, galvanized and pre-painted flat steel. These materials are supplied by the Companys steel processing
products segment and by third parties. Other important raw materials purchased by the Company include chemicals for making the insulating foam for the manufacture of prefabricated steel and foam-insulated panels and polyester and acrylic resins and
fiberglass for the manufacture of FRP panels. All of these raw materials are generally available from a variety of sources. The Companys most important raw material is steel, the price of which is subject to open market fluctuations and may be
very volatile. The Company is not always able to entirely pass on to its customers increases in the price of steel. Accordingly, increases in the cost of steel used as a raw material may cause a financial impact on the Company. See Item 3.D
Risk FactorsRisks Relating to Competition.



Aluminum and Other
Related Products



General



The Company believes that it is currently the largest producer of fabricated
aluminum products in Mexico (based on the Companys general knowledge of the aluminum industry, as well as information gathered from suppliers, clients and competitors) and one of the largest producers of ladders in terms of sales volume in
North America (based on information from the National Home Centers News Top 500 Annual Report, the RICHMARK Group, Inc. and customers of the Company). In addition to its Mexican operations, the aluminum and other related products segment includes
operations in the United States. The United States historically has been the Companys principal export market for aluminum and other related products. In 1998, the Company acquired Alcomex, a manufacturer of industrial aluminum extrusions in
Mexico. Also, in 1998, the Company and Emerson Electric, Co. merged their ladder businesses, setting up a new company called Louisville Ladder Group. The operation includes Escaleras and Davidson Ladders, subsidiaries of IMSALUM, and Louisville
Ladder Company, a subsidiary of Emerson Electric, Co. During 2002, IMSALUM closed its Louisville, Kentucky ladder plant and adapted its production equipment in the Monterrey plant in Mexico to manufacture aluminum and fiberglass ladders. By
concentrating production in Mexico, IMSALUM increased its productivity and lowered production costs. On January 9, 2004, IMSALUM completed the acquisition of the remaining equity of Louisville Ladder Group. See Business Strategy

Aluminum Extrusions



The Company believes it is the largest aluminum extrusion producer in Mexico in terms of sales volume (based on the
Companys general knowledge of the aluminum industry, as well as information gathered from suppliers, clients and competitors). Aluminum extrusions consist of aluminum profiles obtained by extruding heated aluminum billet in an extrusion press.
The Company sells a portion of its aluminum extrusions and further processes the remainder to produce ladders, windows and sliding doors. Aluminum extrusions are sold to a wide array of industries and used in a variety of applications, including
construction applications such as windows, doors, curtain walls and other architectural end products, and in the manufacture of industrial products such as ladders (which are manufactured by the Company). As of December 31, 2003, the Company had an
aluminum extrusion capacity of approximately 70 thousand tonnes per year, of which over 30% was further manufactured into finished products. All of the Companys aluminum extrusion products comply with or exceed the applicable specifications of
the American Society for Testing and Materials.



Ladders



The Company manufactures and distributes an extensive
line of aluminum, fiberglass, steel and wood ladders for industrial and retail markets. Aluminum ladders, made from extrusions produced by the Company, and fiberglass, steel and wood ladders are manufactured in industrial, commercial and household
grades. The Company also manufactures folding wood attic stairways. The Companys aluminum, steel and fiberglass ladders comply with the specifications of the countries to which the products are exported, including the American National
Standards Institute (ANSI) in the United States, the Canadian Standards Association and the European Standard (EN 131-1) for Europe.



Windows and Doors



The Company manufactures prefabricated aluminum and PVC windows and sliding doors. Aluminum windows, made from extrusions produced by the Company, are

Export and Foreign Company Sales



The United States historically has been the Companys principal export market for aluminum and other related products.
Exports to the United States and Canada consist of ladders, aluminum extrusions and aluminum windows. While the United States continues to be the most important export market for the aluminum and other related products segment in terms of volume,
the relative importance of export sales to non-U.S. customers has increased. Exports to the Caribbean, Central America and South America consist primarily of ladders and extrusions. Foreign company sales include ladders sold in the United States.



The Company distributes the products it exports through
independent sales representatives who sell to distributors. Certain large institutional accounts are serviced directly by regional sales managers. The Company distributes its products manufactured by foreign companies through Company and independent
sales representatives. Ladders exported by the Company or manufactured outside Mexico are also distributed through Company and independent sales representatives. A significant portion of the Companys ladders and windows are sold in the United
States to home improvement centers and mass merchandisers such as department stores. The Companys windows are sold in the United States to independent sales representatives.



Competition



The principal factors affecting competition in the aluminum and other related products industry are price, quality, design and engineering capabilities,
technology, timely delivery, new product development and overall customer service. The Company faces significant domestic and foreign competition within the aluminum and other related products segment. The Companys main Mexican competitors in
aluminum extrusions are Valsa, S.A. de C.V., Indalum, S.A. de C.V. and Productos Nacobre, S.A. de C.V. The Company believes it enjoys a competitive advantage over its Mexican competitors due to its vertical integration, design and engineering
capabilities, proprietary technology, broad product line and excellent customer service. Some of the Companys competitors outside of Mexico are large companies that may have greater financial resources than the Company.



The aluminum extrusions industry in the United States is highly fragmented
and highly competitive, with a large number of aluminum extruders operating one or two presses and a small number of large integrated extruders. Competition in the United States market is based primarily on quality, price and overall customer
service. In addition, competition is generally conducted on a regional basis due in part to the large number of extruders and to transportation costs. The Company believes it enjoys a cost advantage over its U.S. competitors due to its vertical
integration and its lower labor costs.



The Mexican and U.S.
ladder markets are highly competitive and concentrated. Competitors in the manufacture of ladders include Escalumex, S.A. de C.V., Productos Nacobre, S.A. de C.V. and Especialum, S.A. de C.V. in Mexico and Werner Ladder Co., Green Bull Ladder and
imports in the United States.



Production Facilities



The Company emphasizes quality and has achieved
significant productivity gains by implementing 6-Sigma programs and improving manufacturing procedures at most of its manufacturing facilities. See The CompanyDescription of Property below.



The following table sets forth the installed capacities and percentage
utilization for the aluminum and other related products segment facilities for the periods indicated.

Research and Development



Because the aluminum segment is a technologically mature industry, the Company does not generally dedicate significant
resources to product development. The Companys engineering staff, however, is engaged in an ongoing product development effort that often involves working closely with the Companys customers, particularly in the development of
specialized applications for aluminum extrusions. The Company also seeks to expand its product offerings through acquisitions.



Capital Expenditures



In the aluminum and other related products segment, the Company plans to undertake several capital expenditure projects intended to modernize facilities,
reduce costs, improve production quality and increase capacity.



During 2003, IMSALUM concentrated capital expenditures on projects to upgrade operating continuity and to improve processes. Additionally, during the first months of 2003, a new window-producing plant began operating in Mexico City. This
facility geographically positions the Company to serve its customers better and has increased the presence of IMSALUM windows in central and southern Mexico by complementing the Companys other facility located in the Monterrey metropolitan
area in northern Mexico. In January 2004, the Company completed the acquisition through IMSALUM of the remaining 49% of the equity in Louisville Ladder Group.



Raw Materials and Suppliers



The principal raw materials for aluminum extrusions are aluminum ingot and aluminum scrap. The Company purchases aluminum ingot from international traders
at international market prices and aluminum scrap from scrap brokers. Aluminum represents approximately 37% of the cost of sales of fabricated aluminum products. Most of the finished aluminum products manufactured by the Company use internally
produced aluminum extrusions. As with lead and steel, aluminum is also subject to open market fluctuations, and therefore the price of aluminum may be very volatile. The Company enters into fixed contracts with respect to the sale of some of its
aluminum products. In order to reduce the impact of any increases in the price of aluminum, the Company enters into forward transactions pursuant to which the Company agrees to buy part of its aluminum needs in the future at a fixed price.



The Company



6-Sigma



6-Sigma is a systematic methodology that utilizes information (management by
facts) and statistical analysis to measure and improve a companys operational performance, practices and systems by identifying and preventing variability in its processes. The goal of 6-Sigma is to increase profits by eliminating variability,
defects and waste which undermine customer loyalty.



As of
April 30, 2004, the Company had 1,070 employees trained in 6-Sigma methodology, of whom 140 were Black Belts, who dedicate all of their time to major process improvement projects; 570 were Green Belts, who spend part of their time in smaller
projects; and 360 were executives trained to give support and ensure the success of the projects. The Company intends to train another 30 Black Belts and 100 Green Belts during 2004. Additionally, more than 7,500 employees were introduced to the
methodology through a one-day seminar. As of April 2004, the Company was carrying out 310 major projects and 730 minor projects. The implementation of 6-Sigma has already resulted in significant savings and further benefits will be obtained when
current projects are completed.



Information Systems



The Company uses advanced process control technology
and information systems which contribute significantly to productivity and product quality and result in competitive advantages. Several of the Companys manufacturing activities include process control sensors which monitor quality control. In
certain critical manufacturing segments this automated process control consists of feedback loops that provide real-time data exchange which compares the data acquired by the sensors with the specified parameters and automatically performs any
required process adjustments.



The Mexican subsidiaries recent
integration into e-Business initiatives (e-Procurement, e-Logistic and e-Travel) has helped achieve cost, time and process optimization.

##### Table of Contents

Most subsidiaries of the Company maintain integrated information systems for purchasing, inventory
management, customer order and production status, billing and accounting. Such systems streamline the processing of customer orders and enable the Company to support its customer service functions, including inventory management, a fundamental
element of the Companys effort to reduce operating costs. In addition, the Company believes such systems are critical to accounting controls and financial management. The Company also believes its management information systems reduce
administrative costs and facilitate timely operational decision making. See Item 5. Operating and Financial Review and ProspectsGeneral.



As a result of the implementation of 6-Sigma and the use of advance process control technology and information systems, the Company believes that it will
continue to increase the efficiency of its IT operations, convert fixed costs into variable costs, guarantee that service standards (such as up-time and response time) required by critical processes of its business are fulfilled, accelerate critical
infrastructure projects while significantly reducing investment requirements and focus internal IT efforts on business functions, rather than basic hardware and software issues.



Environmental Matters



The Companys operations are subject to a wide range of federal and state laws and regulations relating to the
protection of the environment in Mexico and in other countries in which it operates. These laws and regulations concern among other things, wastewater discharges, air emissions, noise, employee health and safety, soil and groundwater contamination
and the use, handling and disposal of hazardous substances and wastes. The principal Mexican legislation is the Federal General Law of Ecological Balance and Environmental Protection (the Ecological Law). The Procuraduría
Federal de Protección al Ambiente (Federal Bureau of Environmental Protection or PROFEPA) monitors compliance with and enforces the Mexican environmental laws. Under the Ecological Law, rules have been promulgated concerning,
among other matters, water quality, air emissions, excessive noise, environmental impacts and the handling and disposal of hazardous substances. PROFEPA can bring administrative and criminal proceedings against companies that violate environmental
laws, and it also has the power to close noncomplying facilities, revoke environmental licenses required to operate such facilities and impose sanctions and fines. The current Mexican administration has stressed environmental protection. In the US,
certain environmental remediation laws can impose the entire cost of site cleanup, regardless of fault, upon any one of a number of statutory categories of parties including companies that owned, operated or sent wastes to a contaminated site.
Future health studies or environmental regulatory classifications in the US or elsewhere concerning certain metal alloys could affect the sales or uses of certain of our products. Finally, environmental regulations relating to multilateral
environmental agreements such as the environmental provisions of NAFTA or the Kyoto Protocol aimed at reducing the emission of greenhouse gasses, can be expected to impose stricter environmental requirements on the Company in the future.



The Company believes that all of its plants, installations and properties
are operating in substantial compliance with all environmental laws and regulations in Mexico and the other countries in which it operates. The Company does not currently anticipate any material impact on its earnings or competitive position as a
result of this compliance. There are no administrative or judicial proceedings pending or known by the Company to be contemplated under environmental regulations or other provisions concerning the environment which would have a material impact on
the business or financial condition of the Company. However, environmental liability risks are inherent in the Companys manufacturing and related operations and there can be no assurance that environmental liabilities or increased
environmental compliance costs could not have a material adverse effect on the business or financial condition of the Company or any of its subsidiaries.



The Company supports environmental conservation through its contributions to the funding for the construction and operation
of public use facilities at a national park in the Monterrey area and the sponsorship of events to foster environmental awareness among Company employees.



Patents and Trademarks



The Company owns or has obtained licenses to use various domestic and foreign patents, patent applications and trademarks related to its products,
processes and business. These patents will expire at various times over the next 20 years. While patents, patent applications and trademarks are important to the Companys competitive position, no single one is material to the Company as a
whole.



The Company owns various trademarks, some of the most
important being IMSA, Zintro, Pintro, True Zinc, LTH, América, Diener, Multypanel, Metl-Span, Cuprum, Davidson, Louisville, Polylit, Acrylit, Cronos, Eleganza, Formet, Varco Pruden Buildings, ASC Pacific, Glasteel, Full Power,

Some of these trademarks are registered in Mexico and all of them are registered in all countries in which the corresponding product is marketed.



Insurance



The Company maintains insurance policies covering its property and business interruption, with respect to its subsidiaries, subject to a $150 million
limit per occurrence. In addition, the Company maintains policies covering, among other things, product liability, civil responsibility, goods while en route (by ground, air or sea), and burglary with policy limits varying from $11 million to $35
million per occurrence. The Company self insures for amounts in excess of these per occurrence limits. In addition, the Company maintains a fleet insurance policy covering all of the Companys vehicles. The Company believes that its insurance
coverage is adequate in scope and amount for the business conducted by the Company.



Description of Property



The Company has a total of 54 plants located in 6 countries across the Americas and Europe (23 in Mexico and 31 abroad).The following chart presents a breakdown of the Companys plants in Mexico as of December 31, 2003 with
their respective locations:

Item 5Operating and Financial Review and Prospects



The following discussion should be read in conjunction with the Consolidated Financial Statements and the related notes thereto included in this annual
report. The Consolidated Financial Statements have been prepared in accordance with Mexican GAAP, which differ in certain respects from U.S. GAAP, in particular by requiring Mexican companies to recognize certain effects of inflation. Note 19 of the
Notes to Consolidated Financial Statements provides a description of the principal differences between Mexican GAAP and U.S. GAAP, as they relate to the Company, and a reconciliation to U.S. GAAP of the Companys net income and
stockholders equity.



The Mexican Institute of Public
Accountants (MIPC) has issued Bulletin B-10, Recognition of the Effects of Inflation on Financial Information, Bulletin B-12, Statement of Changes in Financial Position, and Bulletin B-15, Foreign Currency
Transactions and Translation of Financial Statements of Foreign Subsidiaries (See Notes 2.b and 3.a to the Consolidated Financial Statements) which outline the inflation accounting methodology that is mandatory for all Mexican companies
reporting under

##### Table of Contents

Mexican GAAP. The Third Amendment to Bulletin B-10, which has been effective since January 1, 1990, requires that all
financial information be presented in constant pesos (having the same purchasing power for each period indicated taking into account inflation) as of the date of the most recent balance sheet presented. The presentation of financial information in
constant pesos is intended to recognize certain effects of inflation on the financial statements and to permit comparisons between comparable periods in comparable monetary units. Except where otherwise indicated, financial data for all periods in
the Consolidated Financial Statements and throughout this annual report have been restated in constant pesos with purchasing power as of December 31, 2003. References in this annual report to constant amounts are to inflation-adjusted
numbers and to nominal amounts are to unadjusted numbers. Unless otherwise specified, all growth rates in the following discussion are stated in constant terms. Bulletin B-10 also requires that the Company restate non-monetary assets to
current replacement cost in the case of inventories. Effective January 1, 1997, in accordance with the Fifth Amendment to Bulletin B-10 issued by the MIPC, property, plant and equipment are stated at the lower of use value or indexed value; with
respect to fixed assets of Mexican origin, indexed value is measured by the NCPI, whereas equipment of foreign origin is restated by means of indices of the country of origin and translated at the exchange rate at the date of restatement. The NCPI
and indices of the countries of the Companys foreign subsidiaries are being applied to restate other non-monetary assets, non-monetary liabilities and the components of stockholders equity.



Overview



Grupo Imsa, a diversified industrial company, operates in four core businesses: IMSA ACERO (steel processed products);
ENERMEX (automotive batteries and related products); IMSATEC (steel and plastic construction products); and IMSALUM (aluminum and other related products). The Company operates manufacturing and distribution facilities in Mexico, the United States,
Europe and throughout Central and South America.



The
Companys 2003 sales totaled US$ 2,779 million, 5.5% above the previous year. Due to stagnation of the markets in which the Company participates and the increased cost of many of its inputs, particularly steel, energy and other raw materials,
operating margins fell in 2003. However, projects to improve efficiency and reduce costs resulted in operating expenses falling from 11.8% of sales in 2002 to 11.0% in 2003, offsetting part of the gross margin decline.



The Company acknowledges that its companies operate in a global marketplace;
therefore, an important effort is made to continue to be a flexible organization that can adapt to changing market conditions. Consequently, the Company has adopted a philosophy of continuous change and improvement based on methods such as 6-Sigma.



An overview of results, expectations for 2004 and major
projects is explained for each business segment:



IMSA ACERO



During 2003, higher demand in Asia caused global steel prices to rise,
thereby increasing the cost of IMSA ACEROs main raw materials. Because prices of the companys final products did not keep pace with rising costs, operating margin was adversely affected. During the first months of 2004, international
steel prices soared as demand grew and scarcity of raw materials to produce steel increased. This resulted in a substantial increase in the costs of IMSA ACEROs raw materials. Under normal economic conditions, the Company has been able to
adjust its end product prices to reflect changes in the costs of its main raw materials. Although, as a result, the Company has not materially been affected by these price increases in the past, there can be no assurance that it will not be
materially affected in the future.



In September 2003, IMSA
ACERO concluded the expansion of APMs hot-rolled steel production capacity from 1.5 to 2.2 million tonnes per year. This project increased production capacity by eliminating production and material handling bottlenecks and installing more
efficient equipment. The additional production capacity opens the door to new markets and will allow IMSA ACERO to continue growing in its traditional markets.



ENERMEX



ENERMEX had a positive year in 2003, posting record figures for production, revenues and operating income. This business has pioneered the implementation
of 6-Sigma, a methodology that has produced tangible results. ENERMEX manufactures world-class automotive batteries and works with high efficiency and globally competitive costs. As a result, for the fifth consecutive year ENERMEXs operating
income grew, despite an environment characterized by pressure on prices. Although higher lead prices during the first months of 2004 have increased the cost of producing batteries, these increased costs were not immediately reflected in the price of
part of ENERMEXs sales volume.

During 2003, the Company consolidated its position in its North American markets, leading to an increase
in volume while significantly reducing operating costs and expenses. The years main initiative was a change in distribution strategy in Mexico which included the closure of small distribution centers to enhance the Companys independent
distributor network and the relocation of the closed Tlaxcala plants production to other Mexican facilities.



IMSATEC



Non-residential construction in the United States contracted in 2003, resulting in a decline in sales volumes and operating margins for the IMSATEC companies that serve this segment, particularly VP Buildings. To
offset the adverse market conditions, VP Buildings is going through a restructuring of its operations to reduce costs and enter new markets with innovative solutions for areas such as the maintenance and modification of existing buildings. For 2004,
expectations for the Mexican and US non-residential industry have improved, therefore, the Company anticipates an improvement in this divisions results.



IMSALUM



Despite the difficult conditions in the ladder market in 2003, IMSALUMs operating profit increased for the second consecutive year, reflecting its
strategy of reducing costs and increasing productivity. At the beginning of 2004, IMSALUM finalized the purchase of 100% of Louisville Ladders. During the first months of 2004 new contracts were awarded to supply ladders in the United States. The
Company believes that the additional volume combined with a growing construction market in Mexico should result in higher sales and a margin improvement for this business.



General



Growth Through Investments and Acquisitions



The Company has grown through a series of strategic acquisitions, joint ventures and other strategic initiatives (including capital expenditures) aimed at
expanding and diversifying the Companys products and markets.



In the steel processing segment, after acquiring Industria Galvanizadora in 1997, a galvanizing and painting steel plant from AHMSA in 1999 and Steelscape in 2000, IMSA ACERO acquired certain assets of Pinole Point Steel from Material
Sciences Corporation in 2002. The Pinole Point Steel transaction gave IMSA ACERO 270,000 tonnes per year of additional galvanized steel capacity and 160,000 tonnes per year of additional pre-painted steel capacity. IMSA ACERO has concentrated the
plants production capacity in pre-painted steel. In 2003, IMSA ACERO merged IMSA and APM into a new entity called IMSA-MEX which now controls IMSA ACEROs operations in the Mexican market.



Since December 1998, the Company has been party to a joint venture with
Johnson Controls to manufacture and distribute automotive batteries in Mexico and South America. A joint venture in Mexico between the Company and Johnson Controls serves the Mexican market and exports batteries to the United States and other
countries. The Company and Johnson Controls also are partners in GES Battery Systems (formerly GES America), which is a distribution network that serves medium and small clients in the United States and Canada. The Company, Johnson Controls and
Varta originally partnered to form a joint venture in South America as part of the 1998 arrangements. The joint ventures expanded the partners global manufacturing, marketing and distribution capabilities to better serve original equipment and
aftermarket automotive battery customers. In October 2002, Johnson Controls acquired Vartas Automotive Battery Division. The Company believes the production capacity of the joint ventures in Latin America is the largest in the region (based on
the Companys market share analysis in major Latin American countries which shows that only one competitor operates in different regions of Latin America).



In September 2001, the Company acquired the assets of Varco Pruden Buildings from The LTV Corporation. Beginning in October 2001, the Company
consolidated Varco Pruden Buildings results into its steel and plastic construction products segment. The Company believes that Varco Pruden Buildings is one of the largest companies in North America in the pre-engineered metal buildings
market (based on reports of the Metal Building Manufacturers Association). Headquartered in Memphis, Tennessee, it has eight plants in the United States and Mexico that produce metal buildings and their components and a joint venture in Brazil,
Medabil, which also produces metal buildings. Varco Pruden Buildings provides integral solutions for the construction of large buildings such as manufacturing plants, warehouses, commercial facilities, offices, schools and churches. In July 2002,
IMSATEC, through Empresas Stabilit, acquired Lightfield, Europes second-largest FRP panel company.

##### Table of Contents

In January 2004, IMSALUM completed the acquisition of the remaining 49% of the equity of Louisville
Ladder Group from Emerson Electric Co.



The Company has
invested significantly in its operations to position itself for future growth and profitability and believes that the financial impact of these investments has yet to be fully reflected in the Companys results of operations.



Level of Export Sales



In 2001, 2002 and 2003, export sales accounted for 46.4%, 53.9% and 54.0% of
total net sales of the Company, respectively. The increases in 2002 and 2003, compared to 2001, resulted mainly from the acquisition of Varco Pruden Buildings in the United States at the end of 2001. See Growth Through Investments and
Acquisitions above.



For purposes of this annual report,
domestic sales refers to sales of products sold in Mexico. Exports include sales of products exported from Mexico and sales of products manufactured and sold by the Companys consolidated foreign subsidiaries, respectively,
regardless of where such products are sold.



Vertical
Integration



The principal raw materials used by the
Company are commodity items such as steel slab, hot- and cold-rolled flat steel coil and, to a lesser extent, lead and aluminum. During 2001, 2002 and 2003, these raw materials represented 42%, 45% and 49%, respectively, of the Companys cost
of sales. To reduce its cost of these raw materials and to insulate the Company from fluctuations in the cost of hot- and cold-rolled flat steel coil and lead, the Company has followed a strategy of becoming more vertically integrated. The Company
has achieved upstream integration in its steel processing products segment through the acquisition of a hot strip mill and additional cold-rolling capacity. The Company has achieved upstream integration in its automotive batteries and related
products segment through the expansion of its lead recycling capacity and in its aluminum and other related products segment through additional aluminum casting capacity. Over time, the Company has broadened its range of downstream, vertically
integrated products in each of its steel processing products, aluminum and other related products and steel and plastic construction products segments.



The Company is a vertically integrated steel processor and, therefore, management believes its gross margin is not as sensitive as that of a primary steel
producer to the cyclicality of prices of raw materials and to variations in the realized sales prices of products. The net sales of the Companys steel processing products are greatly impacted by the net tonnes shipped, prices of its products,
mix of products and mix of its markets (domestic or export and commercial or industrial).



Seasonality



In the
automotive batteries and related products segment, the Company has historically experienced seasonality in its sales, with stronger sales during the winter months of November through January and reduced sales during the summer months. The quarterly
results of operations for the automotive batteries and related products segments may fluctuate as a result of such seasonality. Steelscape, Varco Pruden Buildings and ASC Profiles experience seasonality, with stronger sales in the summer and spring
and reduced sales in the autumn and winter. The products of these subsidiaries are directed to the construction industry, which commonly slows down during cold weather. The Companys other products do not experience significant seasonal
fluctuations.

2003 Compared to 2002



Increased sales volumes in the Companys main business segments and the higher average foreign exchange rate resulted
in a 7.2% increase in net sales in 2003 as compared with 2002. Domestic sales grew 6.8% as a result of an increase in the sales volumes of IMSA ACERO and IMSALUM. Increased sales volumes for IMSA ACERO and ENERMEX and a higher foreign exchange rate
resulted in 2003 foreign sales rising 7.5% and representing 54.0% of total revenues. Gross profit fell 8.7% in 2003, with gross margin declining from 22.2% in 2002 to 18.9% in 2003. The reduction in gross profit and reduced gross margin was
attributable to increases in cost of the main raw materials used by IMSA ACERO and IMSATEC, which were not completely reflected in product prices. Operating expenses rose 0.2% as a result of increased sales. However, operating expenses as a percent
of sales fell from 11.8% in 2002 to 11.0% in 2003. This reduction in operating expenses as a percent of sales reflects the Companys efforts to increase efficiency, as well as economies of scale resulting from greater sales volumes. Operating
income in 2003 was 18.9% below that of 2002, and operating margin declined from 10.4% in 2002 to 7.9% in 2003. These reductions were also attributable to cost increases not being completely reflected in product prices.



2002 Compared to 2001



Net sales increased 19.2% to Ps 29,137 million in 2002 compared to Ps 24,435
million in 2001. This growth was primarily a result of increased sales volumes in the Companys main business segments, higher prices for its steel products, and the consolidation of Varco Pruden Buildings during the full year in 2002. The
Companys gross margin decreased marginally to 22.2% in 2002 compared to 22.4% in 2001 due to the consolidation of the results of Varco Pruden Buildings, a company that generally operates with a lower margin than the average of other Company
businesses. Selling, general and administrative expenses decreased as a percentage of net sales to 11.8% in 2002 compared to 12.9% in 2001. Operating margin in 2002 was 10.4% compared to 9.4% in 2001. In 2002, the integral financing cost was Ps
1,119 million compared to a cost of Ps 4 million in 2001. See Integral Financing Cost (Income) below. Primarily as a result of a higher integral financing cost in 2002, the net income of majority interest in 2002 decreased 14.3% to
Ps 1,470 million compared to Ps 1,715 million in 2001.

2003 Compared to
2002



In 2003, IMSA ACEROs sales volume reached a
historic high, rising 5.9% to 2,166,000 tonnes. The volume of domestic shipments grew 5.1%, while foreign sales volume increased 7.6%. The international steel market experienced fluctuations during 2003. During the first few months of the year,
increased demand in Asia resulted in price increases, which were not sustained as steel purchases in that region declined significantly. Demand in Asia increased once again in the second half of the year and this factor, combined with the economic
recovery in the United States and other important world markets, resulted in higher prices and a tighter market at the end of the year.



The cancellation ahead of schedule of U.S. steel tariffs  which had been established under Section 201 of the U.S. Trade Act  did not affect
steel prices in North America because of the strong worldwide demand and the weakness of the U.S. dollar. During 2003, IMSA ACERO continued successfully to penetrate new market niches which, combined with the improvement in the global steel industry
which benefitted foreign sales, served to raise IMSA ACEROs sales volume. IMSA ACEROs 2003 revenues rose 10.8% compared to 2002. Domestic sales grew 10.2%, while foreign sales were up 12.0% and represented 37.3% of total revenues. The
growth in IMSA ACEROs revenues reflects both an increase in sales volume and higher prices.

##### Table of Contents

Operating income for 2003 declined by 31.4%. Operating margin was 8.2% in 2003, compared to 13.3% in
2002. In 2003, the cost of IMSA ACEROs main raw materials  such as steel, zinc, aluminum and energy  rose, but the cost increases were not totally reflected in the price of its products. However, operating expenses as a percent of
sales declined year-over-year, as a result of Company-wide efficiency initiatives and economies of scale associated with greater sales volume, reducing the impact of higher raw material costs on IMSA ACEROs operating results.



2002 Compared to 2001



IMSA ACEROs 2002 revenues increased by 17.5% to Ps 13,288 million
compared to Ps 11,306 million in 2001. IMSA ACEROs sales volume rose 13.8%, to 2,047,000 tonnes in 2002. Domestic shipments grew 9.9%, while foreign sales volume increased 24.0%. The company continued to successfully penetrate sectors such as
the automotive and maquila (inbond manufacturing) industries during 2001. During 2002, the international steel market underwent important structural changes as a consequence of the corrective measures that the United States implemented in March
2002, as a result of an investigation carried out by the International Trade Commission under Section 201 of the U.S. Trade Act. Mexico, as a member of the North American Free Trade Agreement, was excluded from any restrictions. A more orderly
market for the steel industry in general, and especially in North America, resulted in an upswing in prices and in the IMSA ACERO companies sales volumes. During 2002, IMSA ACERO continued to grow successfully in sectors such as the automotive
and maquila industries in Mexico. Additionally, certain sectors, such as electrical appliances, consumed growing quantities of steel, reflecting the establishment of new plants in Mexico.



In 2002, operating income grew 42.4% compared to 2001. The operating margin was 13.3% in 2002, compared with 10.9% in 2001.
In 2002, the increase in volumes and prices, combined with a successful strategy for purchasing raw materials, contributed to the improvement in margin. In addition, economies of scale and IMSA ACEROs efforts to increase efficiency resulted in
lower operating expenses as a percent of sales compared with the prior year. In its second complete year as part of IMSA ACERO, Steelscapes profit increased significantly; in fact, this company posted the highest growth of all IMSA ACERO
businesses.

2003 Compared to 2002



Battery sales volume reached another historic high in 2003, increasing year-over-year by 4.1% to a total of 22.7 million batteries, largely as a result of
a 6.0% increase in foreign sales volume. Foreign sales volume represented 74.1% of the segments total sales volume for 2003. An increase in sales in the United States was the main source of growth in ENERMEXs sales volume in 2003
compared to 2002.



ENERMEXs sales volume grew in Latin
America, reflecting increased sales in Brazil and Central America, and the company recovered part of the volume that had been lost in the Argentinean market during 2002 as a result of the crisis in that nation.



ENERMEX reported 2003 revenues of Ps 4,823, which was 5.6% above the previous
year. Domestic sales fell 2.7%, but foreign sales grew by 11.8%. The decline in domestic sales was a result of a reduction in battery sales volume to

OEMs, reflecting the contraction in the Mexican automotive assembly sector in 2003. Foreign sales grew because of an
increase in sales volume and a greater peso-dollar exchange rate in 2003 and amounted to 60.5% of ENERMEXs total 2003 revenues.



Operating income in 2003 was 24.6% above the previous year. Operating margin was 20.6%, compared to 17.4% in 2002. The improvement in operating margin
reflects several complementary factors: the upswing in sales volume resulting in economies of scale; progress with the process of increasing quality and reducing costs through the standardization of operations with best operational and
administrative practices; the companys efforts to make its distribution network more efficient; and a significant reduction in fixed costs because of the closing of a plant at the end of 2002, with the redistribution of its capacity among the
other Mexican production facilities. In South America, ENERMEXs operating margin improved as a consequence of an upswing in the Argentinean economy and the reorganization of the distribution network to reduce costs.



2002 Compared to 2001



ENERMEX reported year 2002 revenues of Ps 4,568 million, 2.5% above the
previous year. The revenue increase was largely a consequence of higher sales volume. Battery sales continued to rise in 2002, increasing by 5.2% to a total of 21.8 million batteries for the year, largely as a result of 7.3% growth in foreign sales
volume.



Operating income in 2002 was 7.2% above the previous
year. Operating margin was 17.4%, compared with 16.7% in 2001. The improvement in operating margin reflects the upswing in sales volume resulting in economies of scale; progress with the process of increasing quality and reducing costs through the
standardization of operations with best operational and administrative practices; and ENERMEXs efforts to make its distribution network more efficient. Moreover, to reduce costs, at the end of the year, ENERMEX closed its Tlaxcala plant in
Mexico, redistributing its capacity among the other plants. Despite the Argentinean crisis and the general uncertainty in the markets of South America, ENERMEX made the necessary adjustments to its operations and was able to remain operationally
profitable in the region.

2003 Compared to
2002



Due to a reduction in non-residential construction
in the United States and a slowdown in the Mexican economy, 2003 was a difficult year for the IMSATEC companies. IMSATECs annual revenues increased 4.2%. Domestic sales were 1.8% above the previous years, while foreign sales increased
4.8% and represented 80.2% of total revenues. This growth was largely a result of the increased peso-dollar foreign exchange rate, since a large part of this segments revenues are denominated in U.S. dollars.



Operating income fell 45.9% in 2003. Operating margin declined from 5.9% in
2002 to 3.1% in 2003. The decrease in operating income reflects the higher cost of this segments main raw materials and the difficulty of adjusting IMSATECS end product prices to reflect those increased costs because of the contraction
of the main markets in which IMSATEC operates. In Chile, greater competition and the appreciation of the Chilean peso resulted in increased imports and a reduced potential for export.

##### Table of Contents

In 2003, non-residential construction in the United States fell and a large proportion of prefabricated
metal building producers posted a reduced profit or even a loss. VP Buildings managed to maintain its level of sales, but its margin was affected because it was unable to pass increased costs to customers. Despite the difficult environment in
IMSATECs markets in 2003, this segments main companies posted sales levels similar to 2002, with growth limited by their significant exposure to the non-residential construction industry in the United States.



2002 Compared to 2001



The annual revenues of IMSATEC increased 52.0% to Ps 8,252 million in 2002.
This growth was largely a result of the consolidation of Varco Pruden Buildings during the entire year 2002.



Operating income grew 28.4% in 2002 to Ps 488 million. The operating margin declined from 7.0% in 2001 to 5.9% in 2002. The reduction in margin was mainly
due to Varco Pruden Buildings having lower margins than the average of the other IMSATEC businesses.



Aluminum and Other Related Products

2003 Compared to 2002



Aluminum profiles sales volume grew 4.4% in 2003, reflecting an increased volume in both domestic and foreign markets because of an upswing in residential
construction. IMSALUMs total revenues grew 1.8% in 2003. Domestic sales rose 5.9%, while foreign sales declined 1.9% and represented 50.8% of total revenues. The growth in domestic sales reflects the increase in extrusion and window sales due
to an increase in demand from the residential construction industry and the higher exchange rate. The reduction in foreign sales was a consequence of reduced ladder sales because of the difficult market conditions in the United States and increased
competition from Asian imports.



Operating income was
13.8% above that of 2002. Operating margin increased from 5.5% in 2002 to 6.2% in 2003. This improvement in results reflects the companys efforts to increase efficiency. During 2003, initiatives to reduce costs and expenses and the 6-Sigma
projects that were implemented beginning at the end of 2001 continued to produce results. Despite the average price of aluminum being 6% higher year-over-year, gross margin remained constant and operating expenses as a percent of sales fell from
15.1% in 2002 to 14.4% in 2003.





2002 Compared to 2001



IMSALUMs total revenues fell 6.6% in 2002 to Ps 3,029 million. The decrease in sales reflects the difficult environment in the construction industry
during 2002, lower aluminum prices which affected the prices of IMSALUM products and the elimination of accounts with low profitability.



Operating income in 2002 increased 15.6%. The operating margin increased from 4.4% in 2001 to 5.5% in 2002. This improvement reflects IMSALUMs
efforts to increase efficiency. During 2002, the 6-Sigma projects that had been implemented beginning at the end of 2001 began to produce results. IMSALUM carried out 200 projects this year, generating significant savings. Additionally, IMSALUM
closed its die workshop in Monterrey in order to concentrate die manufacturing at the workshop in Mexico City, which is more efficient. IMSALUM also closed its Louisville, Kentucky plant in the United States, transferring ladder production to the
Monterrey plant which operates with lower costs.

Integral Financing Cost (Income)



Pursuant to Mexican GAAP, statements of operations are required to present all financial effects of operating and financing
the business under inflationary conditions. For presentation purposes, all such effects are included under Integral Financing Cost (Income) and include: (i) interest earned on cash and temporary investments; (ii) interest paid on
borrowed funds; (iii) foreign exchange gains or losses associated with monetary assets and liabilities denominated in foreign currencies; and (iv) losses resulting from holding monetary assets exposed to inflation net of gains resulting from having
monetary liabilities adjusted for inflation. Integral financing cost related to and incurred during the construction or the installation of fixed assets may be capitalized under Mexican GAAP. Such integral financing cost related to construction
projects includes interest costs and foreign exchange losses generated from debt denominated in foreign currencies net of the related monetary gain.



The following table sets forth the components of integral cost (income) of financing for each of the periods indicated.

2003 Compared to
2002



The Company reported an integral financing cost of
Ps 742 million in 2003, compared to a cost of Ps 1,119 million in 2002. This change reflects the foreign exchange loss declining from Ps 1,198 million in 2002 to Ps 738 million in 2003, as a consequence of the Mexican peso depreciating 13.0%
vis-à-vis the U.S. dollar in 2002, but only 8.4% in 2003. The 4.0% inflation in 2003 produced a gain from monetary position of Ps 344 million, compared to Ps 472 million the previous year. In addition, interest expense fell 17.7% in 2003,
reflecting the decline in the LIBOR reference rate, to which almost all of the Companys debt is indexed, and the contracting of loans with lower spreads over LIBOR.



2002 Compared to 2001



The Company reported an integral financing cost of Ps 1,119 million in 2002 compared with Ps 4 million in 2001. This change reflects the foreign exchange
result declining from a gain of Ps 279 million in 2001 to a loss of Ps 1,198 million in 2002, as a consequence of the Mexican peso appreciating 4.5% vis-à-vis the U.S. dollar in 2001, but depreciating 13.0% in 2002. The 5.7% inflation in 2002
produced a gain from monetary position of Ps 472 million, compared with Ps 387 million the previous year. Interest expense fell 36.0% in 2002, reflecting the decline in the LIBOR reference rate, to which almost all of the Companys debt is
indexed, and the contracting of loans with lower spreads over LIBOR.



Other
Expenses, Net



In 2003, the Company reported other
expenses of Ps 192 million, largely from the amortization of this years portion of the acquisition of companies above book value during the past years and the disposal of certain fixed assets by some of the Companys businesses.



Income Taxes and Employee Profit Sharing



The Company and its Mexican subsidiaries file an annual consolidated income
and asset tax return. The benefit resulting from the fiscal consolidation is recognized in the Companys consolidated financial statements. As a result of a change in the Mexican income tax law, starting in 1999, the allocation of tax results
to the Companys subsidiaries is limited to 60% of the Companys participation in the common equity of the subsidiary, and the remaining portion is treated on an individual basis. Additionally, estimated income tax payments are determined
and filed by the subsidiaries and not on a consolidated basis. The Mexican income tax rate is 33%. In addition, aside from wages and agreed-upon fringe benefits, the Company and its Mexican subsidiaries are required by law to provide to their
workers a share of the profits of these companies equal to 10% of their taxable profit. See Note 13 of the Notes to the Consolidated Financial Statements.

The effective corporate income tax rate was 24.7% for 2001, 21.6% for 2002 and 29.9% for 2003. The
effective rate of corporate employee profit sharing was 2.6%, 4.5% and 3.9% in 2001, 2002 and 2003, respectively.



The Mexican income tax rate was 34% in 2003 and will be 33% in 2004 and 32% in 2005 and thereafter. The Company recalculated its deferred income tax
liability recorded as of December 31, 2001, as a result of the deferred income tax effect of the reduction in 2002 rates. The 2003 rates were then applied to temporary differences based on their estimated reversal date. The 2002 income statement
reflects the statutory rate changes on deferred income tax of Ps 117 million.

Summary of Material Contractual Obligations and Commercial Commitments



As of December 31, 2003, the Company estimates that
it had approximately 6 million Euros, $21.2 million and Ps 9.1 million in standby letters of credit.



On April 5, 2000, the Company, through a subsidiary who acted as agent, entered into an agreement with Enron Energía Industrial de Mexico, S. de
R.L. de C.V., for the provision of electrical power generation capacity. The stock of this company was sold to Tractebel of Belgium, and on December 14, 2001, its name was changed to Tractebel Energía de Monterrey, S. de R.L. de C.V
(Tractebel). Under the terms of such agreement, Tractebel will supply power needs for most of the Companys subsidiaries in Mexico from 2002 through 2017.



As mentioned in other sections of this annual report, the Company, through its main subsidiaries, has executed several
agreements for the purchase of raw materials. In some of these agreements the Company is committed to purchase a determined percentage of its needs for raw materials, depending on the terms and conditions under which the agreements were executed.
Also, in most of the agreements the price of the raw materials is subject to market prices and complex formulas that make it difficult to estimate the amount of the commitments contained in the agreements.



The Company continually monitors various government rules, regulations and
other policies and programs, including international trading rules and environmental policies and programs, in order to assess whether the implementation of these policies could affect the Companys operations. The Company is not aware of any
new government rules, regulations or policies or programs that are going to be implemented or that are currently anticipated to be implemented which would significantly affect the Companys operations.



The following summarizes the Companys derivative financial instrument
contracts outstanding as of December 31, 2003:



| |  | Foreign currency forward contracts (Forward Contracts)  Some of the subsidiaries maintain a favorable commercial trade position in US dollars. This position motivated the
Company to enter into Forward Contracts establishing a fixed exchange rate for each transaction. In accordance with the agreement the

Company is obligated to sell the dollar amount at the exchange rate agreed in the contract. If the
exchange rate in the market at the due date is below the fixed exchange rate agreed, then the Company receives the spread; if the exchange rate is above the agreed fixed exchange rate, the Company pays the difference. As of December 31, 2003 the
total outstanding amount of Forward Contracts was US$50.2 million. At the same date, the fair value would represent a favorable valuation for the Company of US$586 thousand.

States. Additionally, the Company entered several hedge agreements to protect 70% of the indirect consumption of gas, as Tractebel consumes gas to produce electricity that is sold to the Company based on a gas price formula. The summary of the
hedging contracts mentioned before as of December 31, 2003, is as follows:

Since the acquisition
of the remaining portion of Louisville Ladder Group on January 9, 2004, the Company has begun to enter into forward transactions pursuant to which it agrees to buy aluminum in the future at a fixed price.



Critical Accounting Policies and Estimates



The Companys significant accounting policies are more fully described
in Notes 2 and 3 to the Consolidated Financial Statements. The preparation in accordance with Mexican GAAP of the Companys Consolidated Financial Statements requires the Company to estimate and make assumptions about future events that may
affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. Future events and their effects cannot be determined with absolute certainty; therefore, the determination of such estimations and assumptions requires the
exercise of judgment. Actual results may differ from those estimates, and such differences may be material to the financial statements. The Company, however, believes that there are no critical accounting policies and estimates that may materially
affect its more significant judgments and estimates used in the preparation of its Consolidated Financial Statements and, therefore, have a material impact on the Companys Consolidated Financial Statements. The accounting policies which imply
the application of estimates and/or judgments are:



Allowance for doubtful accounts



The Company
determines the allowance for doubtful accounts based on an evaluation of the aging of the receivables portfolio. The amount of the allowance contemplates a periodic evaluation of the economic environment in which the Company operates.



Property, plant and equipment



Property, plant and equipment are depreciated under the straight-line
method, based on the remaining useful lives determined by independent appraisers. The estimated useful lives represent the period the Company expects the assets to remain in service and to generate revenues. The Company based its estimations on
independent appraisals, reports and the experience of its technical personnel.



The methodology used to restate foreign equipment is more fully described in Note 3(e) to the Consolidated Financial Statements, which includes applying the exchange and inflation rates of the country of origin
utilized as permitted by Mexican GAAP. The Company believes this method more accurately presents the fair value of the assets than restated cost determined by applying inflation factors.

Valuation of intangible assets and goodwill



Starting January 1, 2003, the Company adopted the provisions of new Bulletin
C-8 Intangible Assets (Intangible Assets) (Bulletin C-8), which establishes, among other aspects, that project development costs should be capitalized if they fulfill the criteria established to be recognized as an asset. Pre-operating
cost and expenses that are not considered development cost should be recorded as an expense of the period, and intangible assets which are considered not to have defined useful lives are not amortized, but their value is subject to the impairment
test.



For Mexican GAAP purposes, goodwill is the difference
between the price paid and the fair value of the shares and/or net assets acquired that was not assigned directly to an intangible asset. Goodwill is amortized over a period of not more than 20 years.



Under U.S. GAAP, SFAS No. 142 Goodwill and Other Intangible
Assets went into effect in 2002. Under this standard, goodwill is no longer subject to amortization, but instead is subject to an initial impairment review in 2002 and subsequent impairment test to be performed annually by the Company, unless
an event occurs or circumstances change by which it becomes more likely than not that the fair value of the goodwill has been reduced below its carrying amount, in which case an interim impairment test must be performed.



Labor liabilities



Severance indemnities are required by law to be paid to employees terminated
under certain circumstances. Severance compensation is charged to operations when it becomes payable. Seniority premium costs are actuarially calculated based on actual interest rates, using the projected unit credit method and are recognized over
the employees years of service, which is 18 years in accordance with Bulletin D3, Accounting for Employees Benefits, issued by the IMCP. Unrecognized prior service costs and the transition obligation are amortized based
on the expected remaining service lives of employees that is 16 years.



The Company has a defined contribution pension plan with the objective of offering retirement benefits, benefits for total and permanent disability and death benefits. In accordance with this plan, the Company is obligated to contribute to
the pension fund an amount equivalent to 4% of the participants salary as well as additional contributions up to an amount equivalent to 2% of the participants salary when and if the employee decides to make additional contributions. The
benefit to the participants consists of receiving a pension derived from the accumulated amount from each of the individual accounts. A Mexican financial institution administers the contributed funds.



Additional disclosures and assumptions are more fully described in Note 12 to
the Consolidated Financial Statements.



U.S. GAAP Reconciliation



The principal differences between Mexican GAAP and U.S.
GAAP that affect the Companys majority net income and the majority stockholders equity, as more fully described in Note 19 to the Consolidated Financial Statements (Differences between Mexican and United States Accounting Principles),
are related to the accounting treatment of the following items:



| |  | Deferred income taxes and deferred employee profit sharing
| | - | ----------------------------------------------------------



| |  | Restatement of foreign sourced fixed assets
| | - | -------------------------------------------



| |  | Goodwill amortization
| | - | ---------------------



| |  | Capitalization of interest expense
| | - | ----------------------------------



| |  | Pre-operating expenses
| | - | ----------------------



| |  | Other minor differences
| | - | -----------------------



The Mexican GAAP consolidated financial statements include the effects of inflation as provided for under Bulletin B-10, as amended, whereas financial
statements prepared under U.S. GAAP are presented on an historical cost basis. The reconciliation to U.S. GAAP does not include the reversal of the adjustments required under Bulletin B-10, as amended, except for the reversal of the restatement of
foreign sourced fixed assets (see Note 3.e). The application of Bulletin B-10, as amended, represents a comprehensive measure of the effects of price level changes in the Mexican economy and, as such, is considered a more meaningful presentation
than historical cost-based financial reporting.

##### Table of Contents

As mentioned in Note 2.b, the Company restates prior period consolidated financial statements using a
weighted average rate that incorporates the effects of inflation in Mexico for the Companys Mexican operations using NCPI and inflation and currency exchange rate fluctuations in countries in which the Company has foreign subsidiaries (the
Restatement Factor). However, because the Restatement Factor used to restate prior period financial statements incorporates the effects of changes in foreign currency exchange rates through the most recent balance sheet date, it is considered a
difference between Mexican GAAP and U.S. GAAP. For purposes of the U.S. GAAP reconciliation, prior period balances are restated only for changes in the NCPI as discussed in Note 19 (f).



In addition, under Mexican GAAP, the Company accounted for certain 50% owned, jointly controlled operating entities using
proportionate consolidation during 2003, 2002 and 2001 (see Note 2.a). U.S. GAAP requires such investments to be accounted for using the equity method of accounting. The reconciliation of net income and stockholders equity presented do not,
and are not required to, give effect to this difference between Mexican and U.S. GAAP.



Liquidity and Capital Resources



Liquidity



Under Mexican GAAP, the Company presents its consolidated
statement of changes in financial position in accordance with Bulletin B-12, which identifies the generation and application of resources representing differences between beginning and ending financial statement balances in constant pesos. The
changes shown in the Consolidated Financial Statements do not represent cash flow activities.



The Companys liquidity is provided by uncommitted bank credit facilities, short- and long-term debt and cash generated by operations. See Holding Company Liquidity and Financing
Activity below. The Company had extensive capital expenditure programs, which it financed with cash from operations and dollar-denominated indebtedness.



A significant portion of the Companys liquidity is attributable to its resources generated from operating activities. Resources generated from
continuing operations consist of: (i) consolidated net income, which includes the components of integral financing cost (income), adjusted for items not requiring (generating) resources, such as depreciation and amortization and (ii) changes in
current assets and liabilities net of effects from purchases of businesses. Such resources increased 50.1% in 2003 to Ps 2,932million from Ps 1,953million in 2002. These resources were used to finance capital expenditures. See
Financing Activity below.



The Company
anticipates that its liquidity needs during 2004, 2005 and 2006 will be met by additional short- and long-term borrowings and cash generated by operations.



The Company has long-term debt maturing during each of the years ending 2004, 2005, 2006, 2007, 2008 and 2009 of Ps 1,469
million, Ps 1,824million, Ps 1,806million, Ps 1,983million, Ps 1,455 million and Ps 578 million, respectively, substantially all of which is denominated in U.S. dollars. The Company may finance its maturities of long-term
debt through additional bank financing (which may include collateralized bank loans) or debt capital markets and other long-term debt, which may be denominated in U.S. dollars or in Mexican pesos.



The Company continually evaluates strategic acquisitions and other
investments in new businesses and may make additional acquisitions or investments in new businesses (or increase its investment in certain existing businesses) from time to time. In the past, the Company has financed its acquisitions and similar
investments principally through debt instruments, short-term borrowings and internally generated funds. See Financing Activity below and Item 4. Information on the CompanyThe CompanyDescription of Property.
The Company currently anticipates that any future acquisitions or investments in new businesses (or increased investments in existing businesses) would be financed in a similar manner and therefore could result in the incurrence of additional
long-term indebtedness.



At December 31, 2003, the Company had
available the equivalent of $320 million in uncommitted bank credit facilities for short-term borrowings. See Financing Activity below. The Company also uses short-term borrowings to repay maturing short- and long-term debt and for
working capital purposes. Capital expenditures are financed through internally generated funds and long-term debt. See Capital Expenditures below.



At December 31, 2002 and 2003, the Company had cash and cash equivalents totaling Ps 626 million and Ps 870 million,
respectively. The Companys policy is to invest available cash in short-term instruments and securities issued by the governments of Mexico and the United States and Mexican and U.S. banks. The Company observes this policy because most of the
cash needs of the Company are denominated in Mexican pesos and U.S. dollars.

During periods of higher steel prices, the Companys need for working capital usually increases.
Because of these higher prices, additional cash is necessary in order for the Company to maintain the same sales volume and level of inventory of its steel.



The Companys sales volume for most of its businesses is closely correlated with the economic growth of its main trading markets, particularly Mexico
and the United States. During economic slowdowns in these regions, the Companys sales volume may be affected, resulting in lower cash generation. In addition, the Companys ability to generate cash is also affected by volatility in
international steel prices. If the increased prices of raw materials can not be passed on through product prices, the Companys profit margin may decline which would decrease cash generation.



The Company believes that its sources of liquidity as of December 31, 2003
were adequate for the conduct of its business and its financing requirements as of that date.



Holding Company Liquidity



The Company, as a holding company, has no substantial operations and, consequently, is dependent for virtually all of its internal cash flow on financial income, dividends, debt payments and other payments such as administrative fees, from
its subsidiaries. The Company uses these cash sources to pay taxes, service debt, make equity investments, finance the growth of its subsidiaries and pay dividends to its stockholders.



It has been the Companys general policy to have inter-company loans with its subsidiaries in order to receive a
financial income in excess of what the Companys financial expense is with third parties. It has also been the Companys general policy to cause each of its principal subsidiaries to pay dividends in an amount agreed upon with the
subsidiary, taking into consideration the subsidiarys proposed capital expenditures, profitability and any financial covenants in the subsidiarys financing agreements effectively restricting dividend payments. The dividend policies of
the entity proposing to pay the dividend are subject to change at the discretion of its stockholders. The amount of dividends payable by the Company and its subsidiaries is also subject to general limitations under Mexican corporate law.



Financing Activity



The Company negotiates short-term financing with various Mexican and
international banks. Short-term financing consists of lines of credit denominated in Mexican pesos and U.S. dollars. The Company also negotiates long-term financing with both Mexican and international banks. The Company also has incurred unsecured
long-term debt in the form of medium-term notes, bank loans, syndicated loans and peso bonds swapped to dollar debt (as defined below).



As of December 31, 2003, the major borrowings on the Companys balance sheet were as follows:

As of December 31,
2003, outstanding short-term debt (consisting of notes payable to banks) equaled Ps 1,469million, almost all of which was dollar-denominated. The long-term bank loans are also primarily U.S. dollar denominated. As of December 31, 2003, the
Company had unused, uncommitted, short-term credit lines available with banks totaling approximately $320 million. Interest rates on these lines are 2% in U.S. dollars.



In August 1999, the Company obtained, through its subsidiary Enertec Mexico, a syndicated loan for $165 million. The
five-year facility, which had a three-year grace period, had a spread over LIBOR of 212.5 basis points for the first two years, 225 basis points for year three, 237.5 basis points for year four, and 250 basis points for year five. Enertec Mexico
used most of the proceeds to liquidate an account payable it owed to the Company in the amount of $160 million related to the formation of the joint venture in December 1998 under which the Company and Johnson Controls merged their Mexican
automotive battery operations. The Company used all of the proceeds to pay down short-term debt. In May 2001, this facility was replaced with another syndicated loan for $155 million, the major terms and conditions of which are similar to the
earlier facility, but with a better pricing structure. The Company amortized $10 million of its previous loan. The four-year facility had a two-year grace period, a spread over LIBOR of 112.5 basis points for the first two years and 125 basis points
for years three and four. In March 2004, this facility was replaced with another syndicated loan for $140 million. The major terms and conditions are similar to the earlier facility; however, this new facility has a longer term and a better pricing
structure. This new five-year facility has a thirty-month grace period and a spread over LIBOR of 85, 90, 95, 100, and 105 basis points per annum in years one, two, three, four, and five, respectively.



In August 2000, the Company obtained a syndicated loan for $300 million. The
proceeds from the syndicated loan were used to finance the acquisition of Steelscape and IBP and to pay off short-term debt. The syndicated loan was divided into two tranches. The first tranche was for $120 million with a three-year maturity and a
one-year grace period. The second tranche was for $180 million with a five-year maturity and a two-year grace period. The Company paid off $45 million of this loan in advance in 2000. In December 2001, the Company obtained a new long-term syndicated
loan for $380 million. This transaction has allowed the Company to modify the old loan which had an outstanding amount of $231 million, in order to obtain a lower interest rate and to acquire new resources of $149 million to be used principally to
refinance short-term debt. The new syndicated loan was divided into three tranches: the first for $120 million with a two-year maturity has been repaid; the second for $150 million with a four-year maturity; and the third for $110 million with a
five-year maturity which was prepaid in 2003. The lead arranger of the new transaction was Salomon Smith Barney - Citibank, N.A., and the syndicate was made up of: BankBoston, N.A., Wachovia Bank, N.A., BNP Paribas and JPMorgan Chase Bank, as
arrangers, with ten other banks as participants.



In the second
quarter of 2001, the Company obtained a committed credit line of $50 million from the Export Development Corporation of Canada (EDC). The terms provide for a five year amortizing facility with a spread over LIBOR of 162.5 basis points.
This credit line was fully used by the Company in March 2002 to refinance machinery and equipment that have been acquired in the past and to finance new goods and services from Canadian companies.



In June 2003, the Company obtained a multi-currency syndicated loan for Ps
960 million and $70 million, with an 18-month grace period and five-year maturity. The Company used a swap to convert the Ps 960 million loan to US dollar debt equivalent to $92.7 million.



The above-mentioned long-term debt agreements of the Company provide for
various covenants that restrict the ability of certain of the Companys subsidiaries to incur additional indebtedness, as well as require the Company to comply with financial maintenance tests. Additionally, long-term debt agreements of certain
subsidiaries of the Company contain restrictive covenants, which include financial maintenance tests based on the Companys consolidated balances and results. The Companys ability to pay dividends to its stockholders is restricted by the

maintenance tests. Both the consolidated and subsidiary level financial maintenance tests include: (i) the ratio of
operating income plus depreciation and amortization to gross interest expense, which can be no lower than 2.5 under the most restrictive test; (ii) the ratio of bank debt to operating income plus depreciation and amortization, which can be no higher
than 3.5 under the most restrictive test; (iii) issuance of indebtedness restrictions, which prohibit additional indebtedness if the ratio of bank debt to operating income plus depreciation and amortization is greater than 3.5 under the most
restrictive test; and (iv) minimum stockholders equity requirements, which require that there be at least Ps 8,600 million of shareholders equity under the most restrictive test.



As of December 31, 2003, the Company was in compliance with the above
mentioned financial covenants.



In September 2000, the Company
issued medium-term notes for Ps 1,000 million, equivalent to approximately $108 million. The notes were placed in the Mexican market with a spread of 180 basis points over six-months Cetes and have one amortization in the sixth year. Since
the Companys revenues are highly tied to the U.S. dollar, the proceeds of the placement were exchanged to U.S. dollars with an interest rate of 190 basis points over LIBOR via a cross-currency swap. The total proceeds from these notes were
used to pay off short-term debt. The lead underwriter for this transaction was Chase Manhattan Bank, acting through its Mexican brokerage arm, Chase Casa de Bolsa. The notes do not contain any material financial covenants.



On May 30, 2002, the Company successfully completed the placement of two
certificados bursátiles (peso bonds) totaling one billion Mexican pesos. These placements are part of a bond program for issuing up to three billion Mexican pesos that was set up on May 24, 2002 with the Comisión Nacional
Bancaria y de Valores (Mexican National Banking and Securities Commission). The program will remain in existence for four years, during which time the Company is entitled to make several different placements. One of the bond issuances was for Ps
700 million at a fixed interest rate of 10.2%, while the other issue was for Ps 300 million bearing an interest rate of 115 basis points over 182-day Cetes. Both issues have a five year maturity and are payable in one installment. Since the
Companys revenues are closely tied to the U.S. dollar, the Company swapped to convert the total amount of these issues to $104.4 million at an interest rate of 116 basis points over six-month LIBOR.



In September 2002, the Company placed another two issues of certificados
bursátiles (peso bonds) totaling Ps 1.2 billion. One of these issues was for Ps 900 million at a variable interest rate of 140 basis points over 182-day Cetes and maturing in six years. The other issue was for Ps 300 million at a
fixed interest rate of 10.3% and maturing in two years. Both issues are payable in one installment at maturity. The Company used a swap to convert the Ps 900 million issue to $90 million at an interest rate of 98 basis points over six-month LIBOR,
while the Ps 300 million issue was converted to $30 million at an interest rate of six-month LIBOR plus 89 basis points.



In November 2002, the Company placed a fifth issue of certificados bursátiles (peso bond) for Ps 253 million. The peso bond bears a fixed
interest rate of 11.2% and is payable in one installment when it matures in three years. The Company used a swap to convert the Ps 253 million issue to $25 million at an interest rate of 87 basis points over six-month LIBOR.



In May 2003, the Company placed a sixth issue of certificados
bursátiles (peso bond) for Ps 547 million. The peso bond bears a fixed interest rate of 9.3% and is payable in one installment when it matures in six years. Since the Companys revenues are closely tied to the US dollar, the Company
used a swap to convert the issue to $52.6 million bearing interest at a rate of 106 basis points over six-month LIBOR.



On October 6, 2003 the Company established a new program of certificados bursátiles (peso bond) allowing the issuance of up to five billion
Mexican pesos with the Comisión Nacional Bancaria y de Valores (Mexican National Banking and Securities Commission). The program will remain in existence for four years, during which time the Company is entitled to make several
different placements. This program was established to allow the Company fast and efficient access to the debt capital market.



Standard and Poors and Fitch Mexico gave a credit rating of AA to all notes and certificados bursátiles (peso bonds) mentioned above.



Capital Expenditures



The Company made significant capital expenditures between the beginning of
2001 and December 31, 2003 in an effort to expand production capacity and the range of products, reduce costs, improve the quality of its products, improve productivity and maintain compliance with environmental requirements.

B.Compensation



For the year ended
December 31, 2003, the aggregate compensation of the directors and executive officers of the Company paid or accrued in that year for services in all capacities was approximately Ps 2.04 ($.18 million) for non-management directors and Ps 117.6
($10.47 million) for management directors. The Company pays cash bonuses to its executive officers based on managements evaluation of the job performance of each executive officer and his overall contributions to the Company.



The Company has a defined contribution pension plan with the objective of
offering retirement benefits, benefits for total and permanent disability and death benefits. In accordance with this plan, the Company is obligated to contribute to the pension fund an amount equivalent to 4% of the participants salary as
well as additional contributions up to an amount equivalent to 2% of the participants salary when and if the employee decides to make additional contributions. The benefit to the participants consists of receiving a pension derived from the
accumulated amount from each of the individual accounts. A Mexican financial institution administers the contributed funds. Directors who also serve as executive officers are eligible for this plan.



The Company and its Mexican subsidiaries are required by law to provide to
their workers a share of the profits of these companies equal to 10% of their taxable profit. Directors who are executive officers of the operating companies but who are not major stockholders also participate in this profit sharing program.



C.Board Practices



Currently, there are no existing service contracts between the Company or
any of its subsidiaries and any directors of the Company providing for benefits upon termination of such directors employment.



Members of the Companys compensation committee are: Salvador Kalifa Assad, Enrique Zambrano Benítez and Andrés Marcelo Sada Zambrano.
The compensation committee meets up to three times each year and is mainly responsible for the following: (1) fixing the salaries of the executive officers; (2) approving the annual salary increases of those officers; and (3) approving new benefits
or changes to their existing benefits. The Compensation Committee met two times in 2003.

##### Table of Contents

Members of the Companys audit committee are Antonio del Valle Ruiz, Eugenio Garza Herrera and
Ernesto Canales Santos and each are independent under Mexican law. Mr. Eugenio Garza Herrera presides over the audit committee. In accordance with section V of article 14 bis 3 of the Ley de Mercado de Valores (Securities Market
Law), the audit committee shall: (a) generate an annual report on its activities and present it to the administrative council; (b) opine on transactions with related parties referred to in clause d) of section IV of article 14 bis 3 of the
Securities Market Law; (c) propose the hiring of independent specialists in cases where it judges such hiring to be necessary, so that they may express their opinion with regard to the transactions referred to in clause d) of section IV of article
14 bis of the Securities Market Law; and (d) perform other tasks that the Board of Directors may assign to it with the exception of tasks that are reserved for the stockholders meeting or the Board of Directors itself. For additional
information about the responsibilities of the audit committee, see Item 6. Directors, Senior Management and EmployeesBoard PracticesSignificant Differences in Corporate Governance Practices and Item 16C. Principal
Accountant Fees and Services.



By July 31, 2005, the
Company will also need to comply with corporate governance requirements prescribed by Section 301 of the Sarbanes-Oxley Act of 2002 (Sarbanes-Oxley Act), including the need for an independent audit committee (as defined in Rule 10A-3 of
the Exchange Act) and with rules prescribed by the NYSE with respect to audit committee independence and responsibilities. As required by Rule 10A-3, the NYSE has adopted rules that will require the Companys audit committee to: (a) be
comprised of independent directors (as independence is defined under Rule 10A-3) who are also members of the Companys Board of Directors; (b) have direct responsibility for the appointment, compensation, retention and oversight of the
Companys external auditors; (c) establish a complaints procedure for employee concerns with respect to accounting or auditing matters or internal accounting controls; (d) have the authority to engage independent counsel and other advisers; and
(e) have adequate funding to compensate any registered public accounting firm engaged by the audit committee, to compensate any advisers employed by the audit committee and to pay administrative expenses of the audit committee. The Companys
audit committee has written procedures for receiving and responding to complaints from employees. The Company may decide to comply with other new requirements prior to July 31, 2005. With respect to other corporate governance rules, the Company
would be able to continue to follow its home country practices in lieu of NYSE standards, subject only to the requirement that the Company disclose any significant ways in which its corporate governance practices differ from those prescribed by the
NYSE; the following summary complies with this requirement. On or after the date of this annual report, the Company intends to post the following summary (and any updates) to its website.



Significant Differences in Corporate Governance Practices



As a Mexican reporting issuer listed on the Bolsa Mexicana de Valores (the Mexican Stock Exchange) and on
the New York Stock Exchange (the NYSE), the Company is subject to both Mexican corporate governance practices, including those set forth in the Ley del Mercado de Valores (the Mexican Securities Law), Circular
Única de Emisoras issued by the Comisión Nacional Bancaria y de Valores(the Mexican Banking and Securities Commission) and the Reglamento Interior de la Bolsa Mexicana de Valores (the Mexican Stock
Exchanges rules) and to applicable U.S. federal securities laws, including the Securities Exchange Act of 1934 and the Sarbanes-Oxley Act of 2002. The Company is also subject to the listing standards of the NYSE to the extent they apply to
foreign private issuers. The Company is not required to comply with all of the corporate governance listing standards of the NYSE.



In accordance with the requirements of Section 303A.11 of the NYSE listing standards, the following is a summary of the significant ways that the
Companys corporate governance practices differ from the corporate governance standards required for U.S. companies by the NYSE. The Companys corporate governance practices may differ in non-material ways from the standards required by
the NYSE that are not detailed here.



Board of Directors



Under the NYSE standards, a companys board of directors must have a
majority of independent directors.



As a listed company
in Mexico, the Company is subject to the requirement under the Mexican Securities Law that at least 25% of the members of its Board of Directors be independent as determined under the Mexican Securities Law. Under applicable Mexican corporate law,
the Company has an alternate director for each of its directors. The Mexican Securities Law further provides that alternates of independent directors be independent as well. The Company currently has five directors and six alternate directors, who
are independent under Mexican law, out of a total of 13 directors and 13 alternate directors.



The Mexican Securities Law sets forth detailed standards for establishing independence, which differ from those set forth in the NYSE Rules.

##### Table of Contents

In addition, the Company is not required, under Mexican law, to hold executive sessions in which
non-management directors meet without the management or to hold meetings of only independent directors.



Audit Committee



Under
NYSE standards, listed U.S. companies are required to have an audit committee composed of independent directors that satisfies the requirements of Rule 10A-3 promulgated under the Securities Exchange Act of 1934. Foreign private issuers, such as the
Company, must comply with this requirement by July 31, 2005. The Company intends to have an audit committee that is entirely composed of independent directors (as defined by the SECs rules) on or before the July 31, 2005 deadline.



The Company has an audit committee entirely composed of independent
directors, with an independent Chairman. Mexican law requires a company to have an audit committee composed of a majority of independent directors and an independent chairman.



Audit Committee Responsibilities



The NYSE requires certain matters to be set forth in the audit committee charter of listed companies. Mexican law does not require a written audit
committee charter, and the Companys audit committee does not have one. The activities of the Companys audit committee are described under Item 6. Directors, Senior Management and EmployeesBoard Practices in the
Companys 2003 Annual Report on Form 20-F. On or prior to July 31, 2005, as required by the NYSE listing standards and Rule 10A-3, the Company will ensure that the audit committee has authority to engage independent counsel and advisers and
will ensure that the audit committee has appropriate funding, as it may determine, for payment of compensation to registered public accounting firms, advisers and ordinary administrative expenses of the audit committee.



The Mexican Securities Law requires the audit committee of listed companies
to review and provide advice to the Board of Directors on certain matters, including: transactions that involve the purchase or sale of 10% or more of the listed companys assets, the grant of guarantees involving liability for more than 30% of
the value of the listed companys assets, and any transaction with a value of more than 1% of the listed companys assets. The Companys audit committee serves in this capacity.



Other Board Committees



The NYSE listing standards require each listed issuer to have a nominating/corporate governance committee and a compensation
committee of the board of directors, each of which shall be composed entirely of independent directors and shall have a written charter. The NYSE specifies certain matters to be set forth in the nominating/corporate governance committee and
compensation committee charters of listed companies.



Under
Mexican securities laws and regulations, public companies are not required to have any additional board committees apart from the audit committee. The Company does not have a nominating/corporate governance committee. The activities of the
Companys compensation committee are described under Item 6. Directors, Senior Management and EmployeesBoard Practices in the Companys 2003 Annual Report on Form 20-F. The Compensation Committee does not have a written
charter.



Shareholder Voting on Equity Compensation Plans



Under NYSE standards, shareholders must be given the opportunity to vote on
equity-compensation plans and material revisions thereto, except for employment inducement awards, certain grants, plans and amendments in the context of mergers and acquisitions, and certain specific types of plans. The Company does not currently
offer equity-based compensation to its directors, executive officers or employees, and therefore does not have a policy on this matter.



Disclosure of Corporate Governance Guidelines



NYSE-listed companies must adopt and disclose corporate governance guidelines. The Company is not required to adopt corporate governance guidelines under
Mexican law but instead to file annually with the Mexican Banking and Securities Commission and the Mexican Stock Exchange a statement relating to its level of adherence to the Mexican Best Corporate Practices Code.

##### Table of Contents

Code of Business Conduct and Ethics



Under NYSE standards, listed companies must adopt and disclose a code of business conduct and ethics for directors, officers
and employees, and promptly disclose any waivers of the code for directors or executive officers. The Company is not required to adopt a code of ethics under Mexican law. However, over the years the Company has developed a set of business conduct
and ethics principles applicable to all of its officers and employees, and it is currently in the process of codifying these principles into a code of ethics. Once the code of ethics is adopted, the Company expects either to post it to its website
at www.grupoimsa.com or to make it available (in English), upon request and without charge, to the Companys stockholders.



Chief Executive Officer Certification



A chief executive officer of a U.S. company listed on the NYSE must annually certify that he or she is not aware of any violation by the company of NYSE
corporate governance standards. In accordance with NYSE rules applicable to foreign private issuers, the Companys chief executive officer is not required to provide the NYSE with this annual compliance certification. However, in accordance
with NYSE rules applicable to all listed companies, the Companys chief executive officer must promptly notify the NYSE in writing after any executive officer of the Company becomes aware of any material non-compliance with any applicable
provision of the NYSEs corporate governance standards.



D.Employees



At December 31, 2003, the
Company employed 15,772 persons. On average during 2003 approximately 1,000 of the Companys employees were temporary. The steel processing products segment employed 3,690 persons; the automotive batteries and related products segment employed
3,062 persons; the steel and plastic construction products segment employed 5,029 persons; the aluminum and other related products segment employed 3,796 persons; and 195 employees were employed at the holding company level. Of the total of 15,772
employees, 4,397 are employees based outside of Mexico.



The
table below sets forth the number of employees at the end of 2001, 2002 and 2003:



|           |  |        |  |        |  |       
|---------- |  | ------ |  | ------ |  | ------
|           |  | 2001   |  | 2002   |  | 2003  
|IMSA ACERO |  | 3,509  |  | 3,624  |  | 3,690 
|ENERMEX    |  | 3,838  |  | 3,274  |  | 3,062 
|IMSATEC    |  | 4,836  |  | 4,651  |  | 5,029

|CORPORATE  |  | 186    |  | 192    |  | 195   
|GRUPO IMSA |  | 16,373 |  | 15,800 |  | 15,772



Each of the
Companys subsidiaries has entered into collective bargaining or similar agreements with respect to each of its production plants. As is typical in Mexico, such contracts generally have an indefinite term and provide for an annual salary review
as well as a review of other terms and conditions, particularly fringe benefits, every two years. The Company has not experienced a strike in over 20 years and believes its relationship with labor unions is very good.

Each of the Equity Units consists of three Series B Shares and two Series
C Shares, which became separable at the option of the holder in December 2003. To date, these Equity Units have not been separated. The Series B Shares generally have full voting rights. The Series C Shares generally are not entitled to vote, except
on any action that would prejudice the rights of holders of the Series C Shares but not the rights of holders of all other series of the Companys shares.



Each B Unit consists of five Series B Shares, which became separable at the option of the holder in December 2003. To date, these B Units have not been
separated.The Principal Stockholders hold their B Units through the terms of a trust established under Mexican law, as described below.



As a result of their beneficial ownership of B Units, the Principal Stockholders are able to significantly influence matters affecting the Company,
including those submitted to a vote of the Companys stockholders, and have the ability to elect a majority of the Companys Board of Directors and to approve the declaration, amount and payment of dividends and the issuance of debt and
equity securities of the Company.



The Principal Stockholders
have advised the Company that they may exercise their preemptive rights to subscribe for a sufficient number of Series B Shares so that they will own Series B Shares representing a majority of the outstanding Series B Shares, in connection with any
increase in capital by the Company in the future.



The
Principal Stockholders hold a portion of their Series B Shares in the form of B Units through the Trust. The Principal Stockholders intend to ensure that the Trust will hold at least 51% of the Series B Shares at any time outstanding. Each Family
Group has beneficial ownership of 50% of the Trust. Under Mexican law, the trustee acts in all matters as directed by a management committee. The management committee for the Trust consists of four members, two of which are appointed by each Family
Group. The Trust provides that the management committee will vote the B Units held by the Trust and that all B Units must be voted identically. In addition, sales of beneficial interests in the Trust are subject to a right of first refusal, first in
favor of members of the Family Group of which the selling beneficiary is a member and secondly in favor of members of the other Family Group. Offers to sell to members of a Family Group will be made on a pro rata basis. If such beneficial interest
has not been acquired pursuant to the exercise of the right of first refusal, it may be sold to persons outside both Family Groups. The Trust has a duration of 30 years from its inception in 1996 and may be terminated at any time upon the
affirmative vote of the owners of 75% of the beneficial interests in the Trust. Withdrawal of B Units from the Trust also requires the affirmative vote of the owners of 75% of the beneficial interests in the Trust.



At December 31, 2003, ADRs evidencing 3,931,375 ADSs were outstanding
(equivalent to 35,382,375 Equity Units or 6.3% of the total number of shares outstanding). It is not practicable for the Company to determine the number of ADRs beneficially owned by U.S. persons.



B.Related Party Transactions



During the period since the beginning of the Companys preceding three
financial years to the date hereof, the Company has entered into the following material related party transactions:



In 1998, the Company (through ENERMEX), Johnson Controls and Varta AG entered into an agreement to create three joint ventures to manufacture and
distribute automotive batteries in North and South America. The Company and

##### Table of Contents

Johnson Controls partnered to form ENERTEC Mexico which resulted in the combination of the Mexican automotive battery
operations of the Company and Johnson Controls. The Company and Johnson Controls also partnered to form GES Battery Systems, a sales and marking network that serves medium to small clients in the United States and Canada. As described above in
Item 4. History and Development of the CompanyAutomotive Batteries and Related ProductsProductsAutomotive SLI Batteries, the Company exports automotive batteries to the United States by selling them to Johnson Controls
and GES Battery Systems, each of which then re-sells the batteries to major retailers in the United States. The Company believes that the terms of these agreements with each of Johnson Controls and GES Battery Systems are fair.



C.Interests of Experts and Counsel



Not required because this Form 20-F is filed as an annual report.



Item 8Financial Information



A.Financial Statements



See Item 18 for the Companys financial statements.



B.Legal Proceedings



As of the date of this annual report, the Company is involved in a number of legal actions arising in the ordinary course of business, most of which
involve collection matters in which the Company is the plaintiff. In addition, the Company receives personal injury claims as part of the ordinary course of its ladder manufacturing business. The Company does not believe that the outcome of any
individual legal action or the outcome of all currently pending legal actions considered as a whole, even if determined adversely to the Company or its subsidiaries, would have a material adverse effect upon the financial condition, results of
operations or cash flows of the Company and its subsidiaries, taken as a whole.



C.Dividends and Dividend Policy



All of the shares in the Company are entitled to the same dividend and distribution rights, and any dividends must therefore be declared and paid in equal amounts with respect to all outstanding shares. The Company
paid cash dividends on its shares from 2001 to 2004. The table below sets forth the cash dividends per share, as well as the number of shares entitled to such dividends, during the periods indicated. Dividend per share amounts have not been adjusted
for inflation and reflect share amounts outstanding immediately prior to the distribution of such dividend. Peso amounts have been translated into dollars at the rate announced by Banco de Mexico on the first date on which the applicable dividend
was available for payment.

The Company
historically has paid an annual dividend in respect of the previous year after approval by the Companys stockholders at the annual general ordinary stockholders meeting, generally held in the second quarter of the following year. The
dividend is generally made available for payment shortly after this meeting.



The declaration, amount and payment of dividends are determined by majority vote of the holders of Series B Shares, generally, but not necessarily, on the recommendation of the Board of Directors and will depend on
the Companys results of operations, financial condition, cash requirements, future prospects, general business conditions in

the market where it operates, compliance with debt covenants and other factors deemed relevant by the Board of Directors
and the holders of Series B Shares. See Note 9 to the Consolidated Financial Statements regarding the Companys debt covenants. There can be no assurance as to the amount of the dividend, if any, to be paid in a particular year. Furthermore,
due to its holding company structure, the Companys ability to pay dividends is dependent upon its operating subsidiaries ability to pay dividends or make other payments to the Company. See Item 3. Key InformationRisk
FactorsRisks Relating to Holding Company Structure above and Note 9. The Companys Principal Stockholders are able to elect the majority of the members of the Board of Directors of the Company and, as a result, have the power to
determine the outcome of actions requiring the approval of the Board of Directors and the stockholders, including the declaration, timing and amount of dividends.



The Ley General de Sociedades Mercantiles (Mexican Corporations Law) and the Companys by-laws
require that 5% of the Companys net income each year be allocated to a legal reserve fund until such fund reaches an amount equal to at least 20% of the Companys capital stock. As of December 31, 2003, the Companys legal reserve
was Ps 853 million or 20% of the Companys capital stock. Usually, Mexican corporations pay dividends out of earnings (including retained earnings) after an allocation to the legal reserve. Under Mexican tax law, the Company will be required to
pay tax at a rate of 33% on 1.4925 times the amount of any dividend if such dividend is paid from earnings that have not been subject to income tax. As of December 31, 2003, the Company had Ps 758 million of net taxable income that could be
distributed to stockholders free of this tax liability.



While
the Mexican government does not currently restrict the ability of Mexican or foreign persons or entities to convert pesos to dollars, no assurance can be given that the Mexican government will not institute a restrictive exchange control policy in
the future. Any restrictive exchange control policy would adversely affect the Depositarys ability to convert dividends received in pesos into dollars for purposes of making distributions to holders of ADSs. See Item 10. Additional
InformationExchange Controls.



Item 9The Offer and Listing



The Companys Equity Units are traded on the Mexican Stock Exchange and the ADSs are traded on the NYSE. On December 11, 1996, the Company listed its Equity Units on the NYSE in the form of ADSs under the ticker
symbol IMY. The ADSs are evidenced by American Depositary Receipts (ADRs) issued pursuant to a Deposit Agreement, dated as of December 16, 1996, among the Company, The Bank of New York, the registered holders and beneficial
owners of ADRs.



At December 31, 2003, ADRs evidencing
3,931,375 ADSs were outstanding (equivalent to 35,382,375 Equity Units or 6.3% of the total number of shares outstanding). It is not practicable for the Company to determine the number of ADRs beneficially owned by U.S. persons.



The Series B Shares and the Series C Shares comprising the Equity Units
and the Series B Shares comprising the B Units were for six years from December 11, 1996 transferable on the books of the Company only as Equity Units or B Units, as the case may be, and were not separately transferable. To date, none of the Equity
Units or B Units have been separated. The Company does not currently intend to list the B Units on any exchange. See Item 7. Major Shareholders and Related Party TransactionsMajor Shareholders.

Trading on the Mexican Stock Exchange



The Mexican Stock Exchange, located in Mexico City, is the only stock exchange in Mexico. It is organized as a corporation, was founded in 1894 and has
operated continuously since 1907. Trading on the floor of the Mexican Stock Exchange is conducted exclusively by the 29 brokerage firms that are stockholders of the exchange. Trading of securities on the Mexican Stock Exchange takes place between
the hours of 8:30 a.m. and 3:00 p.m., Mexico City time, each business day. Each trading day is divided into six trading sessions with ten-minute periods separating each session. Lot sizes start from 100 shares. Brokerage firms are permitted to buy
odd lots for their own account. Trades in securities listed on the Mexican Stock Exchange may also be effected off the Exchange, subject to certain requirements. However, due primarily to Mexican tax considerations, most transactions in listed
securities are effected through the Exchange. There is no formal over-the-counter market for securities in Mexico. The Mexican Stock Exchange operates a system of automatic suspension of trading in shares of a particular issuer as a means of
controlling excessive price volatility, but under current regulations this system does not apply to the Equity Units, because they trade outside Mexico in the form of ADSs. In addition, the Mexican Stock Exchange can suspend trading in a security
(including those not subject to the automatic suspension system described above) for up to twenty business days if it determines that disorderly trading is occurring with respect thereto. Any increase in the length of the suspension period beyond
twenty business days is subject to the prior approval of Comisión Nacional Bancaria y de Valores (CNBV).



Settlement of transactions involving equity securities is effected two business days after a share transaction on the Mexican Stock Exchange. Deferred
settlements, even by mutual agreement, are not permitted without the consent of the Mexican Stock Exchange and notice to the CNBV. Most securities traded on the Mexican Stock Exchange are on deposit with S.D. Indeval, S.A. de C.V.,
Institución para el Depósito de Valores, a privately owned central securities depositary that acts as a clearing house, depositary, custodian, settlement, transfer and registration institution for Mexican Stock Exchange
transactions, eliminating the need for physical transfer of securities.



The Mexican Stock Exchange is Latin Americas second largest exchange in terms of market capitalization, but it remains relatively small and illiquid compared to major world markets. Although there is substantial participation by the
public in the trading of securities on the Mexican Stock Exchange, a major part of this activity reflects transactions by institutional investors.

Item 10Additional Information



A.Share Capital



Not required because this Form 20-F is filed as an annual report.



B.Memorandum and Articles of Incorporation



Set forth below is a brief description of certain significant provisions of the Companys bylaws. This description does not purport to be complete
and is qualified by reference to the Companys bylaws, as amended, which have been filed as Exhibit 1.1 to this annual report. The following discussion summarizes some of the important aspects of the Companys bylaws.



Organization and Register



The Company is a corporation (sociedad anónima de capital
variable) organized under the laws of Mexico. The Companys deed of incorporation and bylaws were executed on October 15, 1976, and were registered in the Public Registry of Commerce in Monterrey, N.L. on December 16, 1976, under the number
583, folio 257, volume 217, book 3, second auxiliary, deeds of commercial companies, in the commerce section. The Company shall have a term of 99 years, as of May 19, 1997.



Purpose



The Company is a Mexican holding company, with core businesses consisting of: (i) steel processing products, (ii) automotive batteries and related
products, (iii) steel and plastic construction products and (iv) aluminum and other related products. Article Four of the bylaws provides that the Companys purpose is to promote, organize, incorporate, exploit and acquire interests in the
capital stock or equity of any type of profit or non-profit organization engaged in manufacturing, commerce, services or any other type of operations, whether Mexican or foreign, and participate in the administration or liquidation thereof, as well
as other purposes related thereto.



Board of Directors



Management of the Company is vested in its Board of Directors. According to
the bylaws, the Board of Directors consists of a number of directors determined annually by the Companys stockholders at an ordinary general stockholders meeting, which may never be less than seven nor more than 20, each of whom is
elected for a term of one year. Each alternate director is authorized to serve on the Board of Directors in place of its respective director who is unable to attend meetings or otherwise participate in the activities of the Board of Directors. The
Board of Directors has the general power to issue debt instruments on behalf of the Company.



Any stockholder of Series B Shares representing at least 10% of the capital stock is entitled to designate one director and his or her alternate as provided above. When these appointments are complete, the other
directors are appointed by a simple majority of votes of the attending shares, without counting the votes of those minority stockholders who have made the aforementioned appointments.



Under the Mexican Corporations Law, if a director has a conflict of interest with regard to a matter to be considered by the
Board of Directors, the director is required to disclose that conflict of interest before the discussion and vote on the matter. The director is required to refrain from participating in a discussion of the merits of the action and to refrain from
voting on any matter related to such conflict.



Directors
compensation is decided in ordinary general stockholders meetings in the same manner as any other matter considered therein. See Stockholder Meetings. There is no age limit requirement for retirement of directors.



Capital Stock; Voting Rights



The capital stock of the Company is variable. At April 22, 2004, the common
stock, excluding the shares held in treasury, was composed of 2,813,495,290 registered common shares, without par value, divided into 2,336,097,174 Series B Shares with voting rights and 477,398,116 Series C Shares without voting rights, except in
certain limited circumstances. All of the shares constitute the fixed portion of the Companys capital stock and carry the same rights and privileges, except with respect to voting rights, as described below. The bylaws provide that the
variable portion of the capital stock of the Company is limited to no more than ten times the value of the minimum fixed capital. There were no shares representing the variable portion of the capital stock outstanding at April 22, 2004.

##### Table of Contents

At April 22, 2004, the Company held 1,677,500 repurchased shares in treasury, divided into 1,006,500
Series B Shares and 671,000 Series C Shares, which it had acquired within the last twelve months in accordance with Mexican regulations.



Under Article Eight of the bylaws, each Series B Share confers on the holder the right to attend stockholders meetings and the right to one vote per
share. Each Series C Share may vote only in those special meetings of holders of Series C Shares dealing with cancellation of inscription of the Series C Shares or other securities that represent them in the Securities or Special Section of the
Mexican National Securities Registry or de-listing from any domestic or foreign stock exchange where the Series C Shares have been listed. The above is not applicable in the case of cancellation of inscription in quotation systems or other markets
that are not organized as stock exchanges. Holders of Series C Shares are not entitled to attend general stockholders meetings other than as described above. Series C Shares entitle their holders to the same ownership and economic rights
applicable to Series B Shares, including profit sharing and preemptive rights to subscribe (proportionately to their own holdings) to any new shares issued by the Company, within the restrictions and subject to the terms provided in the bylaws. See
Preemptive Rights below.



Under Mexican law,
holders of shares of any series are also entitled to vote as a class on any action that would affect the rights of holders of shares of that series, and a holder of shares of that series would be entitled to judicial relief against any such action
taken without such a vote. The determination whether any action requires a class vote on these grounds would initially be made by the Board of Directors or other party calling for stockholder action. A negative determination would be subject to
judicial challenge by an affected stockholder, and, in such case, the necessity for a class vote would ultimately be determined by a Mexican court of law. There are no other procedures for determining whether a proposed stockholder action requires a
class vote, and Mexican law does not provide much guidance on the criteria to be applied in making a determination.



Each of the Companys Equity Units consists of three Series B Shares and two Series C Shares which were not separable for a period of seven years
from December 11, 1996. See Item 7. Major Shareholders and Related Party TransactionsMajor Shareholders. To date, these Equity Units have not been separated.



Each of the Companys B Units consists of five Series B Shares which were not separable for a period of seven years
from December 11, 1996. See Item 7. Major Shareholders and Related Party TransactionsMajor Shareholders. To date, these B Units have not been separated. As a result of their beneficial ownership of a majority of B Units, the
Principal Stockholders are able to determine the outcome of matters affecting the Company, including those submitted to a vote of the Companys stockholders, and have the ability to elect a majority of the members of the Companys Board of
Directors and to approve the declaration, amount and payment of dividends and the issuance of debt and equity securities of the Company, among other matters. The Principal Stockholders hold their B Units under the terms of a voting trust established
under Mexican law, as described below. An English translation of the trust agreement was filed with the SEC as an exhibit to the Companys annual report on Form 20-F for the fiscal year ended December 31, 1996. The following two paragraphs
summarize some of the important aspects of the trust agreement.



The Principal Stockholders have advised the Company that they intend to ensure that they hold, through the Trust, at least 51% of the Series B Shares outstanding at any time and that, in connection with any increase in capital by the
Company in the future, they plan to exercise their preemptive rights to subscribe for a sufficient number of Series B Shares so that they will continue to own a number of Series B Shares representing a majority of the outstanding Series B Shares.
See Preemptive Rights below. Each Family Group has beneficial ownership of 50% under the terms of the Trust. See Item 7. Major Shareholders and Related Party TransactionsMajor Shareholders.



Under Mexican law, the trustee acts in all matters as directed by a trust
management committee. The trust management committee consists of four members, of which two are designated by each Family Group. The Trust provides that the management committee will vote the B Units held by the Trust and that all B Units must be
voted together on each matter put to a vote. Sales of beneficial interests in the Trust are subject to a right of first refusal, in favor of members of the Family Group. Offers to sell to members of a Family Group must be made on a pro rata
basis. If a beneficial interest has not been acquired pursuant to the exercise of such right of first refusal, it may be sold to persons outside both Family Groups. The Trust has a duration of 30 years and may be terminated at any time upon the
affirmative vote of the owners of 75% of the beneficial interests in the Trust.

Dividends



All of the Companys shares are entitled to the same dividend and distribution rights, and any dividends must be declared and paid in equal amounts
with respect to all outstanding shares.



The declaration,
amount and payment of dividends are determined by majority vote of the holders of Series B Shares, generally, but not necessarily, on the recommendation of the Board of Directors. Any recommendation by the Board will depend on the Companys
results of operations, financial condition, cash requirements, future prospects, general business conditions in the markets in which it operates, compliance with debt covenants and other factors deemed relevant by the Board of Directors and the
holders of Series B Shares. See Note 9 to the Consolidated Financial Statements regarding the Companys debt covenants. There can be no assurance as to the amount of the dividend, if any, to be paid in a particular year. Furthermore, due to its
holding company structure, the Companys ability to pay dividends is dependent upon the ability of its operating subsidiaries to pay dividends or make other payments to the Company. See Item 3. Key InformationRisk FactorsRisks
Relating to Holding Company Structure above and Note 9. The Companys Principal Stockholders are able to elect the majority of the members of the Board of Directors of the Company and, as a result, have the power to determine the outcome
of actions requiring the approval of the Board of Directors and the stockholders, including the declaration, timing and amount of dividends.



Stockholders Meetings



Stockholders meetings may be general or special, and general stockholders meetings may be extraordinary or ordinary. Extraordinary general
meetings are those called to consider certain matters specified in Article 182 of the Mexican General Law of Commercial Corporations, including, principally, amendment of the bylaws, liquidation, merger and transformation from one type of company to
another, as well as to consider the de-listing of the Companys shares and any other securities representing such shares at the Mexican National Securities Registry and in national and foreign stock markets in which they are listed (except from
quotation systems or other markets not organized as stock exchanges), or they may be called to pass a resolution for the creation of Equity Units. All other general stockholders meetings are ordinary. Ordinary general stockholders
meetings are held at least once each year, in the first four months following the close of each fiscal year. Special stockholders meetings are those that meet to address matters that could affect the rights of a particular class of shares and
are subject to the procedural provisions applicable to extraordinary general stockholders meetings.



Generally, the Board of Directors or the statutory auditors call stockholder meetings; however, stockholders representing at least 10% of the capital
stock of the Company (with regard to matters on which holders of Series C Shares may vote, as described above) or stockholders representing at least 10% of the Series B Shares (with regard to matters on which holders of Series C Shares may not vote)
may request in writing, at any time, that the Board of Directors or the statutory auditors call a meeting of the stockholders to discuss the matters specified in their request.



Notice of extraordinary and ordinary general stockholders meetings must be published in the Diario Oficial de la
Federación(Official Gazette of Mexico) or in a newspaper of general circulation in the Companys domicile at least fifteen calendar days prior to the meeting. Notice of special stockholders meetings must be
published in the Official Gazette of Mexico or in a newspaper of general circulation in the Companys domicile at least eight calendar days prior to the meeting.



Stockholders who are recorded on the stockholder registry as holders of one or more shares of the Company must be admitted
to stockholders meetings. The stockholder registry will be closed the day before the date set for a meeting. In order to attend a meeting, stockholders must deposit their shares or their deposit voucher issued by the institution in which their
securities are deposited in return for an admission card which will give them access to the meeting. Shares or vouchers deposited for the purpose of attending stockholders meetings are returned after the meeting adjourns.



The quorum for an ordinary general stockholders meeting is 51% of the
Series B Shares, and resolutions passed require a majority of the votes present to be valid. If a quorum is not obtained, a second meeting may be called pursuant to which action may be taken by a majority of those Series B Shares present, regardless
of the number of those shares.



The quorum for an extraordinary
general stockholders meeting held to address matters where Series C Shares are not entitled to vote is 75% of the outstanding Series B Shares, and resolutions passed require a favorable vote of at least 51% of the outstanding Series B Shares
to be valid. Any change to Article Nine of the bylaws, related to the delisting of the Companys shares at the Mexican National Securities Registry, requires the favorable vote of at least 95% of the total shares of capital stock, as well as
the prior authorization of the Mexican Banking and Securities Commission.

##### Table of Contents

Special stockholders meetings must abide by the rules of procedure described above applicable to
the extraordinary general stockholders meetings.



Extraordinary stockholders meetings held to address matters where Series C Shares are entitled to vote will be legally convened under first or further notice when at least 75% of shares representing the total capital stock are present
and, to be valid, resolutions passed will require a favorable vote of at least 51% of all the shares of capital stock.



Preemptive Rights



In the event of a capital increase for cash, a holder of existing shares of a given series has a preferential right to subscribe for a sufficient number
of the newly issued shares of the same series to maintain the holders existing proportionate holdings of shares of that series; provided, that such right will not apply in the case of a capital increase in connection with (i) a merger; (ii)
convertible debt; (iii) a public offering; (iv) an increase in the capital stock by paying any issued shares in kind or by canceling liabilities owed to the Company; or (v) a placement of shares repurchased by the Company.



Preemptive rights must be exercised within the time period set by the
stockholders meeting that authorizes the capital increase, which may not be less than 15 days following the publication of notice of the capital increase in the Official Gazette and a newspaper of general circulation in the Companys
domicile.



After the period for exercise of rights expires, any
shares which have not been subscribed to by the stockholders pursuant to their preemptive rights may be offered for subscription and payment under the terms and conditions determined by the stockholders meeting which authorized the capital
stock increase or any other terms determined by the Board of Directors or the delegates designated by the stockholders meeting for this purpose.



Reductions in Capital Stock



Except for those reductions in capital stock resulting from the repurchase by the Company of its shares as permitted under Article Ten of the bylaws, the
capital stock of the Company may be reduced pursuant to a resolution passed by the ordinary or extraordinary stockholders meeting, as the case may be. Reductions in the minimum fixed portion of the capital stock must be authorized by an
extraordinary general stockholders meeting, with a subsequent amendment of the bylaws as provided under the Mexican Corporations Law. Reductions in the variable portion of the capital stock, other than the repurchase by the Company of its
shares as permitted under Article Ten of the bylaws, may be authorized by an ordinary general stockholders meeting. The minutes from such a meeting must be subsequently notarized but are not required to be filed with the Public Registry of
Commerce.



Any capital stock reduction must be effected in such
a manner that Series C Shares do not exceed a maximum percentage of 25% of the total capital stock, as provided under Article Six of the bylaws. Reductions in capital stock may be effected to absorb losses, redeem shares or release stockholders from
unpaid balances, allow holders of shares in the variable portion of the capital stock to withdraw or allow repurchase of shares by the Company under Article Ten of the bylaws.



In the event that reductions in capital stock are effected to redeem shares, redemptions must be made on a pro-rata basis;
provided, however, that the redemption value may not be less than the value of the shares set forth in the last preceding financial statements approved by an ordinary general stockholders meeting.



Reductions in the variable portion of the capital stock may be effected
through a partial or total withdrawal by the stockholders, upon notice to the Company as provided under Article 220 of the Mexican Corporations Law, effective: (i) at the close of the current fiscal year if received prior to the last quarter of the
year or (ii) at the close of the next fiscal year if received thereafter. However, stockholders may not exercise a right of withdrawal if it results in a reduction of the fixed non-redeemable portion of the capital stock below the required minimum.
In the event that the Company receives withdrawal requests that will result in a reduction of the capital stock below the required minimum, the Company will be bound to honor only those requests that will not have this consequence, in the order of
receipt. In the event that the Company receives several withdrawal requests simultaneously which altogether may cause a reduction of the capital stock to less than the minimum, the Company shall redeem only those shares that will not have this
consequence, and redemption will be effected proportionately, with regard to each applicant stockholder.



In addition to the provisions of Articles 220 and 221 of the Mexican Corporations Law, Article 15 of the bylaws of the Company states that withdrawals are
subject to payments of redemption value equal to the lesser of: (i) 95% of the



72

##### Table of Contents

market value obtained from the average closing price per share during the 30 trading days preceding the day upon which
the redemption will be effective, during a period that will not be greater than six months and (ii) the value per share set forth in the financial statements of the fiscal period immediately preceeding the fiscal period when the withdrawal is to
take place, as previously approved by the ordinary general stockholders meeting. In the event that the number of days in which the shares have been traded during the six-month period is less than 30, the number of days in which trading
occurred will be considered. In the event that the shares are not traded in such period, the value of the shares will be determined according to the financial statements.



Except for reductions in the capital stock derived from repurchase by the Company of its shares under Article Ten of the
bylaws, any reduction in the capital stock must be entered in the registry maintained for this purpose by the Company.



Redemption of Shares with Distributable Profits



Under Article 16 of the bylaws, an extraordinary general stockholders meeting may authorize a redemption of shares with distributable profits. As
long as the shares are not retired by the Company, there is no reduction of the capital stock pursuant to Article 136 of the Mexican Corporations Law. Redemption may be effected, at the election of the extraordinary stockholders meeting, as
follows: (i) proportionately among stockholders in such a manner that, after the redemption, they hold the same percentage of shares representing capital stock and equity that they held before the redemption; and (ii) in the case of shares traded on
a stock exchange, through the purchase of its shares in such exchange, as dictated by the pricing, terms and other conditions determined by the stockholders meeting, which may in turn delegate this authority to the Board of Directors or
special delegates. Under no circumstances may shares be redeemed in such a manner that the Series C Shares exceed 25% of the capital stock.



Redeemed shares, together with their respective certificates and titles, will be cancelled.



Liquidation Procedure



Under the bylaws, the Company will be liquidated upon dissolution, for which purpose the general stockholders meeting will appoint one or more
liquidators and their respective deputies, who will have the powers provided under the law or as determined and conferred upon them by the general stockholders meeting that appoints them.



In the performance of their duties, the liquidators will proceed as
instructed by the stockholders meeting or, in the absence of these instructions, as provided in the Mexican Corporations Law, based on the following precepts: (i) to conclude any pending business in the manner they deem best; (ii) to pay
credits and loans with the proceeds of the sales of corporate assets, if necessary; (iii) to prepare the final liquidation balance sheet; and (iv) upon approval of the final liquidation balance sheet, to distribute the remaining cash assets equally
among the stockholders in proportion to the number of shares they hold and the stated value thereof.



Foreign Investment Legislation



Ownership by non-Mexicans of shares of Mexican enterprises is regulated by the Ley de Inversión Extranjera (the Foreign Investment Law), which became effective on December 29, 1993 and
replaced the 1973 law on the same subject, and by the Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras(the Foreign Investment Regulations), which was issued in 1988. The Ministry of
Economy and the Foreign Investment Commission are responsible for the administration of the Foreign Investment Law.



Foreign investors may freely participate in up to 100% of the capital stock of Mexican companies or entities. However, the Foreign Investment Law reserves
certain economic activities exclusively for the Mexican state and certain other activities exclusively for Mexican individuals or Mexican corporations (in each case, to which specific foreign investments regulations apply). The Foreign Investment
Law also limits the participation of non-Mexican investors to certain percentages in regard to companies engaged in certain other activities specified therein. As part of the existing restrictions, an approval from the Foreign Investment Commission
will be necessary in order for foreign investment to exceed 49% of the capital stock in existing companies with assets exceeding the amount to be established annually by the Foreign Investment Commission. Mexican corporations, however, are allowed
by the Foreign Investment Law to issue non-voting stock or stock with limited voting rights to foreign investors (Inversión Neutra) which stock is not considered for purposes of the maximum percentages set forth in the
Foreign Investment Law. Mexican and non-Mexican nationals will be entitled to hold, and to exercise the rights of a holder of, the Equity Units, the Series B Shares and the Series C Shares. The Principal Stockholders have advised the Company that
they intend to maintain a control position directly in the form of Series B Shares. See Item 7. Major Shareholders and Related Party TransactionsMajor Shareholders. Pursuant to the Foreign Investment Law, unless appropriate
authorization is obtained, this control position may be transferred only to Mexican nationals.

C.Material Contracts



For a summary of material contracts entered into by the Company or any of
its consolidated subsidiaries outside of the ordinary course of business during the last two years, see Item 4. Information on the Company and Item 5. Operating and Financial Review and Prospects.



D.Exchange Controls



Capital Controls



The Mexican government does not currently restrict the ability of Mexican or foreign persons or entities to convert Mexican
pesos into U.S. dollars or other currencies. Except for the period from September 1 through December 20, 1982, Banco de Mexico has made foreign currency available to private sector companies. The foreign currency that the Company needs to service
its foreign currency obligations, including its outstanding securities, has been available in the open market.



E.Taxation



This section summarizes certain United States federal income and Mexican tax consequences of owning Equity Units or ADSs. It applies only to investors that hold Equity Units or ADSs as capital assets for tax purposes.
This section does not address all material tax consequences of owning Equity Units or ADSs. It does not address special classes of holders, some of whom may be subject to special rules, including:



| |  | tax exempt entities,
| | - | --------------------



| |  | certain insurance companies,
| | - | ----------------------------



| |  | broker-dealers,
| | - | ---------------



| |  | traders in securities that elect to mark to market,
| | - | ---------------------------------------------------



| |  | investors liable for alternative minimum tax,
| | - | ---------------------------------------------



| |  | investors that actually or constructively own 10% or more of the voting stock of the Company,
| | - | ---------------------------------------------------------------------------------------------



| |  | investors that hold Equity Units or ADSs as part of a straddle or a hedging or conversion transaction, or
| | - | ---------------------------------------------------------------------------------------------------------



| |  | U.S. holders (as defined below) whose functional currency is not the U.S. dollar.
| | - | ---------------------------------------------------------------------------------



This section is based on the tax laws of the United States (including the Internal Revenue Code of 1986, as amended, its
legislative history, existing and proposed regulations thereunder, published rulings and court decisions) and Mexico as in effect on the date hereof, as well as on the Convention Between the United States and Mexico for the Avoidance of Double
Taxation and Prevention of Fiscal Evasion With Respect to Income Taxes and its accompanying protocol (collectively, as amended, the Treaty). These laws are subject to change (or changes in interpretation), possibly on a retroactive
basis. In addition, this section is based in part upon the representations of the Depositary and the assumption that each obligation in the Deposit Agreement and any related agreement will be performed in accordance with its terms.



For purposes of this discussion, an investor is a U.S. holder if the investor
is a beneficial owner of Equity Units or ADSs and is:



| |  | a citizen or resident of the United States,
| | - | -------------------------------------------



| |  | a domestic corporation,
| | - | -----------------------



| |  | an estate whose income is subject to United States federal income tax regardless of its source or
| | - | -------------------------------------------------------------------------------------------------



| |  | a trust, if a United States court can exercise primary supervision over the trusts administration and one or more United States persons are authorized to control all
substantial decisions of the trust.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



An investor
who is a U.S. holder is an eligible U.S. holder if:



| |  | the investor is a resident of the United States for purposes of the Treaty,
| | - | ---------------------------------------------------------------------------



| |  | either the investors Equity Units and/or ADSs are not attributable to a permanent establishment or fixed base that the investor maintains in Mexico, or the investors
Equity Units and/or ADSs are so
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



74

##### Table of Contents

attributable but the investor does not carry on, and has not carried on business through the permanent
establishment or fixed base (including, in the case of an individual investor, performing independent personal services) and



| |  | the investor is otherwise eligible for benefits under the Treaty with respect to income and gain from the Equity Units or ADSs.
| | - | -------------------------------------------------------------------------------------------------------------------------------



For purposes of Mexican taxation, an individual is a resident of Mexico if he
has established his home in Mexico. An individual who also has a home in another country will be a Mexican resident for tax purposes if his center of vital interests is in Mexico. A legal entity is a resident of Mexico if it was created under
Mexican law or it has its business management located in Mexico. An individual is presumed to be a resident of Mexico if he is a Mexican citizen, unless such person or entity can demonstrate the contrary. If a legal entity is deemed to have a
permanent establishment in Mexico for tax purposes, all income attributable to such permanent establishment will be subject to Mexican taxes, in accordance with applicable tax laws.



In general, and taking into account the earlier assumptions, for United States federal income and Mexican tax purposes,
holders of ADSs or of ADRs evidencing ADSs will be treated as the owners of the Equity Units represented by those ADSs. Exchanges of Equity Units for ADRs, and ADRs for Equity Units, generally will not be subject to United States federal income tax
or to Mexican tax.



You should consult your tax advisor regarding the United
States federal, state and local and the Mexican and other tax consequences of your owning and disposing of Equity Units and ADSs. In particular, you should confirm your status as an eligible U.S. holder with your advisor, and should discuss any
possible consequences of failing to qualify as an eligible U.S. holder.



Taxation of Dividends



Mexican Tax
Considerations



Dividends paid to holders (Mexican
individuals and foreign residents) with respect to the Companys shares (including shares comprising Equity Units represented by ADSs) are not subject to a tax withholding.



The Company will be required to pay tax at a rate of 33% on 1.4925 times the amount of any dividend paid during 2004 if the
dividend is paid from earnings that have not been subject to income tax.



U.S. Tax Considerations



Under the United States federal income tax laws, and subject to the passive foreign investment company (PFIC) rules discussed below, the gross amount of any dividend paid by the Company out of its current or accumulated earnings
and profits (as determined for United States federal income tax purposes) is subject to United States federal taxation for U.S. holders. Dividends paid to a noncorporate U.S. holder after December 31, 2002 and before January 1, 2009 that constitute
qualified dividend income will be taxable at a maximum rate of 15% provided that the individual holds the Equity Units or ADSs for more than 60 days during the 120-day period beginning 60 days before the ex-dividend date, and meets other holding
period requirements. The Internal Revenue Service has announced that it will permit taxpayers to apply a proposed legislative change to the holding period requirement described in the preceding sentence as if such change were already effective. This
legislative technical correction would change the minimum required holding period retroactive to January 1, 2003, to more than 60 days during the 121-day period beginning 60 days before the ex-dividend date. Dividends paid by the Company
with respect to the Equity Units or ADSs generally will be qualified dividend income. The gross amount of the dividend payment includes any Mexican tax that may be withheld from the dividend payment, even though U.S. holders will not actually
receive this amount. The dividend is taxable to a U.S. holder when the U.S. holder, in the case of the Companys shares (including shares comprising Equity Units), or the Depositary, in the case of ADSs, receives the dividend, actually or
constructively. The dividend will not be eligible for the dividends-received deduction generally allowed to United States corporations in respect of dividends received from other United States corporations. The amount of the dividend distribution
that a U.S. holder must include in income will be the U.S. dollar value of the peso payments made, determined at the spot Mexican peso/U.S. dollar rate on the date the dividend distribution is includable in the income of the U.S. holder, regardless
of whether the payment is in fact converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date the dividend payment is includable in income to the date the payment is
converted into U.S. dollars will be treated as ordinary income or loss, and will not be eligible for the special tax rate applicable to qualified dividend income. This gain or loss will generally be income from sources within the United States for
foreign tax credit limitation purposes. Distributions in

##### Table of Contents

excess of current and accumulated earnings and profits (as determined for United States federal income tax purposes) will
be treated as a return of capital, to the extent of a U.S. holders basis in the U.S. holders Equity Units or ADSs, and thereafter as capital gain.



Subject to certain limitations, any Mexican tax withheld in accordance with the Treaty and paid over to Mexico will be creditable against a U.S.
holders United States federal income tax liability. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the maximum 15% tax rate. To the extent a refund of the tax withheld is
available to you under Mexican laws or under the Treaty, the amount of tax withheld that is refundable will not be eligible as a credit against the United States federal income tax liability. Dividends will constitute income from sources outside the
United States but generally will be passive income (or, in the case of certain holders, financial services income), which is treated separately from other types of income for purposes of computing the foreign tax credit
allowable to U.S. holders.



Distributions of additional shares
to U.S. holders with respect to their shares comprising Equity Units or ADSs, if made as part of a pro rata distribution to all stockholders of the Company, generally will not be subject to United States federal income tax.



Taxation of Capital Gains



Mexican Tax Considerations



Income from the sale of Equity Units by Mexican individuals and foreign
residents is exempt from any Mexican tax if the transaction is carried out through any Mexican Stock Exchange concessioned under the Mexican Securities Market Law or through any foreign exchange located in a country with which Mexico has a treaty to
avoid double taxation, provided that the sale does not take place como operaciones de registro o cruces protegidos or any other denomination that prevents the sellers from accepting more competitive offers than those received
before and during the period of sale.



U.S. Tax
Considerations



Subject to the PFIC rules discussed below,
upon a sale or other disposition of Equity Units or ADSs, a U.S. holder will recognize capital gain or loss for United States federal income tax purposes equal to the difference between the U.S. dollar value of the amount realized and the U.S.
holders tax basis, determined in U.S. dollars, in such Equity Units or ADSs. Capital gain of a noncorporate U.S. holder that is recognized on or after May 6, 2003 and before January 1, 2009 is generally taxed at a maximum rate of 15% where the
holder has a holding period greater than one year. Additionally, the gain or loss will generally be from sources within the United States for foreign tax credit limitation purposes.



Additional U.S. Tax Considerations



PFIC Rules



The Company believes that Equity Units or ADSs should not be treated as stock of a PFIC for U.S. federal income tax purposes, but this conclusion is a
factual determination made annually and thus may be subject to change. If the Company were to be treated as a PFIC, unless a U.S. holder elects to be taxed annually on a mark-to-market basis with respect to the Equity Units or ADSs, gain realized on
the sale or other disposition of the Equity Units or ADSs would in general not be treated as capital gain. Instead, the U.S. Holder would be treated as if the U.S. Holder had realized such gain and certain excess distributions ratably
over the U.S. Holders holding period for the Equity Units or ADSs and would be taxed at the highest tax rate in effect for each such year to which the gain was allocated, together with an interest charge in respect of the tax attributable to
each such year. In addition, dividends that the U.S. Holder receives from the Company will not be eligible for the special tax rates applicable to qualified dividend income if the Company is a PFIC either in the taxable year of the distribution or
the preceding taxable year, but instead will be taxable at rates applicable to ordinary income.



A U.S. holder who owns Equity Units or ADSs during any year that the Company is a PFIC must file Internal Revenue Service Form 8621.



Other Mexican Taxes



There are no Mexican inheritance, gift or succession taxes applicable to the ownership, transfer or disposition of the
Companys shares, Equity Units or ADSs, provided, however, that gratuitous transfers of shares, Equity Units or ADSs

The carrying amounts
of the Companys cash equivalents, accounts receivable, accounts payable and current notes payable approximate fair value because they have relatively short-term maturities and bear interest at rates tied to market indicators, as appropriate.
The Companys long-term debt consists of debt instruments that bear interest at variable rates tied to market indicators and as such the carrying values are not materially different from the estimated fair market values at December 31, 2003.



The Company has issued a medium term note and six
peso bonds in the Mexican financial market for a total amount of Ps 4,000 million, equivalent to $410 million, which were outstanding as of December 31, 2003. The medium term note and each of the peso bonds are at different rates and
terms. The payment of the principal of the medium term note and the peso bonds will be one bullet payment at the due date also detailed in the table below, together with the related Swaps.



Because the Companys revenues are closely tied to the performance of
the U.S. dollar, the Company, through the use of combined swaps, has converted its fixed and variable interest rates and proceeds from these medium term note and peso bonds into dollars, with terms and conditions as described in the relevant note.

Foreign Currency Exchange Rate Risk



Although a portion of the Companys sales is made in other currencies, the Companys monetary liabilities at any
given time are denominated mostly in U.S. dollars. Because of this, the Company is exposed to foreign currency exchange rate risk, as a result of variations in the value of the Mexican peso with respect to the U.S. dollar. During the years ended
December 31, 2003 and 2002, the Mexican peso experienced devaluation and appreciation with respect to the U.S. dollar of approximately 8% and 13%, respectively. The exchange rates as published by the Banco de Mexico of the Mexican peso to the
U.S. dollar as of December 31, 2003 and 2002 were Ps 11.2360 and 10.3613, respectively.



The Companys consolidated assets and liabilities include inventories and fixed assets purchased with foreign currencies and other monetary assets and liabilities denominated in foreign currencies. Such amounts,
stated in U.S. dollars and their Mexican peso equivalents, are as follows:

The Companys
monetary assets as of December 31, 2003 consisted of $37million in cash and cash equivalents, $220million in accounts receivable and $69million in other monetary assets. Its monetary liabilities consisted of $61million in short-term debt, $203million in accounts payable, $810million in long-term debt, including the current portion, and $63million in other monetary liabilities.



Commodity Price Risk



The Company is exposed to commodity price risk through its use of commodities, such as zinc, lead and aluminum, as raw
materials; such commodities account for a significant portion of the Companys raw materials needs. Under normal economic conditions, the Company has been able to adjust its end product prices to reflect changes in the costs of its main raw
materials. Although, as a result, the Company has not materially been affected by these price increases in the past, there can be no assurance that it will not be materially affected in the future.



Natural Gas Price Risk



The cost of natural gas is an important component of the Companys cost structure. The Company is subject to natural
gas cost fluctuations and can be affected by major price increases. Natural gas is distributed in Mexico by Pemex. As a result of the price volatility of natural gas in the international market, Pemex decided to offer a fixed price contract for
natural gas to Mexican companies. In February 2001, the Company signed a contract with Pemex at a fixed price of $4.00 per million BTU for the period beginning on January 1, 2001 and ending on December 31, 2003. During 2003, the Company entered into
hedge agreements to protect the natural gas price at its plants in Mexico and in the United States, including the gas coming from the Tractebel Plant, for approximately 55% and 70% of their consumption, respectively.



The Company actively manages the risks associated with the cost of natural
gas, taking into consideration the future expectations of experts in the natural gas industry. In 2001, the Company decided to sell, through a swap agreement with Enron North America, Inc. (Enron), its rights under the contract with
Pemex. In connection with the swap agreement

with Enron, Enrons affiliate, Enron Corp., executed in favor of the Company a Collateral Guarantee Agreement in
which Enron Corp. irrevocably and unconditionally guaranteed the payment obligations of Enron under the swap agreement in an amount up to $15 million. In November 2001, Enron failed to comply with its obligations under the swap agreement and, as a
result, the Company terminated the swap agreement. After Enron filed for bankruptcy under Chapter 11 of the United States Code, the Company filed proof of claims for the payment of loss of $25,606,804, plus accrued interest, calculated in accordance
with the terms of the swap agreement, and the payment of $15,000,000, plus accrued interest, for amounts due pursuant to the Collateral Guarantee Agreement. In the first half of 2004, Enron filed its fifth amendment to its plan of reorganization.
The confirmation hearings regarding this plan of reorganization were initiated in June 2004 and are currently on-going. In addition, Enron has also filed an avoidance action seeking to avoid any payment on any guarantee made or given by Enron Corp.
In response to the avoidance action filed by Enron, several creditors, including the Company, have filed objections, also referred to as adversary proceedings, to the avoidance action. The proceedings on the avoidance action are currently on-going.
The Company believes that it is unlikely that payment will be forthcoming, if at all, with respect to the Companys claims against Enron until the above processes have been resolved. The Company continues to evaluate alternative approaches in
order to totally or partially collect on these claims. These defaults have not had and are not expected to have a material adverse impact on the financial condition or results of operation of the Company.

INDEPENDENT AUDITORS REPORT



To the Board of Directors and Stockholders of

Grupo Imsa, S.A. de C.V.:

San Pedro Garza Garcia, N.L.



We have audited the accompanying consolidated balance sheets of Grupo Imsa, S.A. de C.V. (A Mexican corporation) and subsidiaries (the Company) as of December
31, 2003 and 2002, and the related consolidated statements of operations, changes in stockholders equity and changes in financial position for each of the three years in the period ended December 31, 2003, all expressed in millions of Mexican
pesos of purchasing power as of December 31, 2003. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits. The financial
statements of the Companys consolidated subsidiaries mentioned in Note 2, which statements reflect total assets constituting 3% of consolidated total assets as of December 31, 2003 and 2002, and total net sales constituting 8%, 9% and 13% of
consolidated total net sales for the years ended December 31, 2003, 2002 and 2001, respectively. Those statements were audited by other auditors whose reports have been furnished to us, and our opinion, regarding the amounts reported by these
companies, is based solely on the reports of such other auditors.



We conducted
our audits in accordance with auditing standards generally accepted in Mexico and with the Standards of the Public Company Accounting Oversight Board (United States of America). 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 and that they are prepared in accordance with accounting principles generally accepted in Mexico. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits and the reports of other auditors provide a reasonable basis for our opinion.



In our opinion, based on our audits and the reports of the other auditors, such consolidated financial statements present fairly, in all material respects, the financial
position of the Company as of December 31, 2003 and 2002, and the results of their operations, changes in their stockholders equity and changes in their financial position, for each of the three years in the period ended December 31, 2003, in
conformity with accounting principles generally accepted in Mexico.



Our audits
also included auditing the adjustments to convert the consolidated financial statements of Louisville Ladder Group LLC and ABC Battery Company LLC into accounting principles generally accepted in Mexico for purposes of consolidation.



Accounting principles generally accepted in Mexico vary in certain significant respects from
accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 19 to the consolidated financial statements.



The accompanying financial statements and the independent auditors report have been
translated into English language for the convenience of readers.

INDEPENDENT AUDITORS REPORT



To the Board of Directors and Stockholders of

ABC Battery Company, L.L.C.

Delaware, USA



| | 1. | We have audited the consolidated balance sheets of ABC Battery Company, L.L.C. and subsidiaries as of December 31, 2003 and 2002, and the related consolidated statements of
operations, changes in stockholders equity (net capital deficiency) and comprehensive income and cash flows for the years then ended. These consolidated financial statements are the responsibility of the Companys management. Our
responsibility is to express an opinion on these consolidated financial statements based on our audits.

reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An

| | 3. | In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of ABC Battery Company, L.L.C. and
subsidiaries as of December 31, 2003 and 2002, and the results of their operations and their cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

| | 4. | As described in Note 20 to the financial statements, Enertec Argentina SRL, a subsidiary of ABC Battery Company, is co-defendant party involved in lawsuit relating to a supply
agreement infringement for which no provision for a loss contingency has been recorded in the accompanying financial statements. The settlement amount depends on the final decision in Court and is not feasible to estimate fees and expenses that the
Company will incur in defending itself in this litigation.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. | The accompanying consolidated financial statements have been prepared assuming that ABC Battery Company, LLC will continue as a going concern. The Company has recorded significant
recurring losses and has a net capital deficiency that raises substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments relating to the recovery and the classification of
assets or their value, or to classification of liabilities that might result from the outcome of this uncertainty.

b. Translation of Financial Statements of Foreign Subsidiaries and Associated Companies  The financial statements of consolidated

as of the balance sheet date and the amounts of the statement of operations are translated using the exchange rate at the balance sheet date after the application of the third amendment to Bulletin B10. Prior years financial statements are
restated using an average factor based on sales in accordance with the Bulletin B15.



Exchange rate differences arising from translation of their financial statements are classified within stockholders equity as part of the excess (insufficiency) in capital restatement until the disposal of the
net investment.



|3. | SIGNIFICANT ACCOUNTING POLICIES:
|-- | --------------------------------



Changes in Accounting Policies  Starting January 1, 2003, The Company adopted the dispositions of new Bulletin C-8 Intangible
Assets which establishes, among other aspects, that project development costs should be capitalized if they fulfill the criteria established to be recognized as an asset. Pre-operating costs and expenses that are not considered development
costs should be recorded as an expense of the period, and intangible assets which are considered with no defined useful lives are not amortized, but their value is subject to the impairment test. The unamortized balance of capitalized pre-operating
costs and expenses as of December 31, 2002 valued under the former Bulletin C-8 rules, will continue to be amortized according to that Bulletin.



Starting January 1, 2003, The Company also adopted the dispositions of new Bulletin C-9 Liabilities, Provisions, Contingent Assets and Liabilities
and Commitments, which establishes, among other aspects, more precision in concepts related to provisions, accruals and contingent liabilities. This bulletin also establishes new dispositions for the accounting recognition of provisions, the
use of the present value calculations, and the settlement of obligations when occurs early or being substituted by a new obligation.



The significant accounting policies of the Company are as follows:



a. Effects of Inflation on the Financial Statements  The consolidated financial statements of the
Company recognize the effects of inflation in accordance with Bulletin B10, Recognition of the Effects of Inflation in Financial Information, as amended, issued by the IMCP. The Third Amendment to Bulletin B10 requires that
all financial statements and related notes be presented in constant pesos as of the date of the most recent balance sheet presented. Factors derived from the National Consumer Price Index (NCPI), published by Banco de México, are
applied to restate the financial statements of the Mexican companies to constant pesos. The Companys consolidated financial statements reflect the effects of inflation, as follows:



(1) Bulletin B12 Statements of Changes in Financial Position (B-12) addresses the presentation of
statements of changes in financial position once the financial statements have been restated to constant Mexican pesos in accordance with the Third Amendment to Bulletin B10. Pursuant to Bulletin B12, the changes in financial position
reflected in the consolidated statements of changes in financial position are based on the differences between the beginning and ending balance sheet balances stated in the pesos of purchasing power as of December 31, 2003. The changes in
inventories, investment in shares and property, plant and equipment are adjusted by the applicable result from holding nonmonetary assets. The monetary gains or losses and foreign exchange gains and losses (except for realized gains or losses)
are noncash transactions that are classified as operating activities, included in consolidated net income.



(2) The operations of foreign subsidiaries and associated companies are not considered an integral part of the Company, thus, the inflation effect
confronted by the foreign companies in their country are applied when consolidating the financial statements.



(3) Capital stock, additional paidin capital, initial deferred tax effect, reserve for repurchase of own shares and retained earnings, have been
restated using the applicable NCPI and inflation rate of the country of origin from the time the amounts were contributed or generated in order to maintain their original purchasing power.

(4) The gain or loss from monetary position represents the effects of inflation on the Companys net
monetary liabilities and assets, based on the NCPI, for Mexican companies, and the inflation rate of the country of origin for foreign subsidiaries.



(5) The excess (insufficiency) in capital restatement represents principally the gain (loss) from holding non monetary assets which is the increase
(decrease) in the values of nonmonetary assets as adjusted to their replacement cost and specific indices in excess of, or below the increase attributable to general inflation as measured by the NCPI.



b. Cash Equivalents  The Company considers all
highlyliquid temporary investments with original maturity of three months or less to be cash equivalents. Such investments consist primarily of overnight funds at banks and are stated at market value, which approximates cost plus accrued
interest.



c. Financial
InstrumentsAssets and liabilities resulting from any financial instrument are being held to maturity, and valued at their acquisition cost. The effects of valuation of the financial instruments, including their cost and yield
are recorded in the corresponding year in the statement of operations.



Financial instruments for hedging purposes, are valued using the same criteria of valuation of the assets or liabilities hedged, and the effect of such valuation is recognized in the income statement, net of costs, expenses and income from
the assets or liabilities whose risks are being hedged.



d. Inventories and Cost of Sales  Inventories are stated at the lower of replacement cost or realizable value. Cost of sales is stated at estimated replacement cost at the time of sale. Replacement costs of finished
goods and production in process are based on the most recent fully absorbed cost of related production. Replacement costs of related raw materials, tools and parts are determined based on purchase prices prevailing at the balance sheet date.



e. Property, Plant and Equipment  Fixed
assets of Mexican origin are restated by factors derived from the NCPI, whereas equipment of foreign origin are restated by means of indices of the country of origin and translated at the exchange rate at the date of restatement. Repairs and
maintenance are expensed when incurred. Depreciation is computed under the straightline method, based on the remaining useful lives of the related assets determined by independent appraisers. The remaining estimated useful lives in years are
as follows:



|                         |  |      |  |       |  |      
|------------------------ |  | ---- |  | ----- |  | -----
|                         |  | 2003 |  | 2002  |  | 2001 
|Buildings                |  | 26.2 |  | 27.44 |  | 27.63
|Machinery and equipment  |  | 12.8 |  | 11.19 |  | 12.07
|Transportation equipment |  | 3.5  |  | 3.10  |  | 3.98 
|Computer equipment       |  | 2.5  |  | 2.51  |  | 2.45 



f. Construction
in Progress  Construction in progress includes costs incurred during the construction and installation of fixed assets, including capitalized integral financing cost (income). The integral financing cost (income) capitalized is
determined based only on financing specifically obtained for the construction and installation of fixed assets. Construction in progress is restated as mentioned in Note 3.e.



g. Investment in Associated Companies  Investments in which the Company holds between a 20% and 50%
ownership interest and does not have effective control nor share control, as in the joint-ventures, are accounted for using the equity method.



h. Other Assets  Costs and expenses incurred in the development phases which will have future economic benefits and they fulfill the
criteria for being recognized as an asset in accordance with Bulletin C-8, are capitalized and amortized based on the straight-line method over five years. The cost incurred that does not fulfill the criteria, and the related investigation cost, are
recorded in the statement of operations of the period in which they occur. Pre-operating cost incurred after January 1, 2003, is recorded directly in statement of operations of the period in which they occur.



Pre-operating expenses capitalized as of December 31, 2002 are amortized
using the straight-line method over 10 years. Other nonmonetary assets are restated by applying NCPI factors to the historical cost of the related assets.

##### Table of Contents

i. Excess of Cost Over Fair Value of Net Assets Acquired of Subsidiaries  The excess
of cost over fair value of net assets acquired of subsidiaries is restated utilizing factors derived from the NCPI and is amortized on a straight line basis over 20 years.



j. Excess of Fair Value Over Cost of Net Assets Acquired of Subsidiaries  Excess of fair value over cost
of net assets acquired of subsidiaries (negative goodwill) is classified as a deferred credit and restated utilizing factors derived from the NCPI and is amortized by the straightline method during the period in which the acquired
companies are integrated into the Companys operations, not exceeding five years.



k. Employee Benefits  Severance indemnities are required by law to be paid to employees terminated under certain circumstances. Severance compensation is charged to operations when it becomes
payable. Seniority premium costs are actuarially calculated based on actual interest rates, using the projected unit credit method and are recognized over the employees years of service, which is 18 years in accordance with Bulletin D3,
Accounting for Employees Benefits, issued by the IMCP. Unrecognized prior service costs and the transition obligation are amortized based on the expected remaining service lives of employees that is 16 years.



The Company has a defined contribution pension plan with the objective of
offering retirement benefits, benefits for total and permanent disability and death benefits. In accordance with this plan the Company is obligated to contribute to the pension fund an amount equivalent to 4% of the participants salary as well
as additional contributions up to an amount equivalent to 2% of the participants salary when and if the employee decides to make additional contributions. The benefit to the participants consists of receiving a pension derived from the
accumulated amount from each of the individual accounts. A respected financial institution administers the contributed funds.



l. Provisions-When the Company has a present obligation arising from a past event which may result in the utilization of economic
resources that can be fairly estimated, provisions are being recognized. Such provisions are recorded at net present value when the discount effect is material.



m. Foreign Currency TransactionsAssets and liabilities denominated in foreign currencies
are valued at the applicable exchange rates as of the balance sheet dates. Transactions in foreign currencies are valued at the applicable exchange rates at the respective dates of the transactions. Foreign exchange gains and losses are reflected in
current operations, except for amounts capitalized to fixed assets as a part of capitalized integral financing cost (income).



n. Revenue Recognition Revenues are recognized in the period in which the risks and rewards of ownership of the inventories are
transferred to the customers, which generally coincides with the delivery of products to customers in satisfaction of orders. A subsidiary in the segment of steel and plastic construction products, which account for 14% of consolidated net sales,
uses the percentage of completion method recognizing revenues based upon the ratio of material cost incurred to estimated total material on customer contracts.



o.Income Tax, Tax on Assets and Employee ProfitSharing  The provisions for income tax (ISR) and employee
profitsharing (PTU) are recorded in results of the year in which they are incurred. Deferred income tax assets and liabilities are recognized for temporary differences resulting from comparing the book and tax values of assets and liabilities
plus any future benefits from tax loss carry-forwards. Deferred PTU is derived from temporary differences between the accounting result and income for PTU purposes and is recognized only when it can be reasonably assumed that they will generate a
liability or benefit, and there is no indication that this situation will change in such a way that the liabilities will not be paid or benefits will not be realized.



Tax on assets paid that is expected to be recoverable is recorded as an advance payment of income tax and is presented with
deferred income taxes.



p. Earnings Per Share
 Earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding during each period.



q. Estimates and Assumptions  The preparation of financial statements in accordance with accounting principles generally accepted in
Mexico requires management to make estimates and assumptions which affect the amounts reported in the financial statements and the accompanying notes. Although these estimates are based on managements best knowledge of current events, actual
results may differ.

|(1) | In December 2001 Grupo Imsa obtained a syndicated credit for US$380 million that modified the one existing at December 31, 2000 for US$300 million which had an unpaid balance of
US$231 million as of that date. In addition to negotiate a lower interest rate in the transaction, the additional funds for US$149 million were used principally to refinance shortterm debt.

|(2) | In May 2001, the contract was modified in its amount (originally of US$165 million) maturity and interest rates, as shown in this note. At December 31, 2003 in accordance with the
credit agreement, the liability has been reduced for Ps 193 (US$17.22 millions), amount deposited into a collateral account. The administrative agent shall apply such funds deposited in the collateral account always to amortize the principal and
interests of the credit. Subsequent amortization will be in February, 2004.

|(3) | Grupo Imsa has issued a Medium Term Note and six Peso Bonds in the Mexican financial market for a total amount of Ps 4,000 equivalent to US$410 million, at
different rates and terms which are detailed on the table below. Since the revenues of the Company are highly tied to the US dollar, through combined Swaps, Grupo Imsa converted the fixed and variable rates and proceeds from these programs, into
loans with variable rates in dollars with the descriptions and conditions disclosed in this note. The payment of the principal of the Medium Term Note and the Peso Bonds will be one bullet payment at the due date also
detailed in the table below, together with the combined Swaps:

Certain longterm debt agreements of the Company provide for various covenants that restrict the
ability of certain of Grupo Imsas subsidiaries to incur additional indebtedness, as well as require compliance with financial maintenance tests. Additionally, longterm debt agreements of certain subsidiaries of the Company contain
restrictive covenants that include financial maintenance tests based on the Companys consolidated balances and results. The Companys ability to pay dividends is restricted by the consolidated financial maintenance tests. Both the
consolidated and subsidiary level financial maintenance tests include: (i) the ratio of operating income plus depreciation and amortization to gross interest expense (ii) the ratio of bank debt to operating income plus depreciation and amortization,
(iii) minimum stockholders equity. The most restrictive consolidated ratio levels that must be maintained are (i) no lower than 2.5, (ii) no higher than 3.5, (iii) maintain as minimum level Ps. 8,600, respectively.



As of December 31, 2003, the Company was in compliance with the above
mentioned financial covenants.



|10. | FINANCIAL INSTRUMENTS:
|--- | ----------------------



a. The following summarizes the Companys derivative financial instrument contracts at December 31, 2003:



 Foreign currency forward contracts (Forward Contracts)  Some of
the subsidiaries maintain a favorable commercial trade position in US dollars. This position motivated the Company to enter into Forward Contracts establishing a fixed exchange rate for each transaction. n accordance with the agreement the Company
is obligated to sell the dollar amount at the exchange rate agreed in the contract. f the exchange rate in the market at the due date is below the fixed exchange rate agreed, then the Company gets the spread; if the exchange rate is above the agreed
fixed exchange rate, the Company pays the difference. As of December 31, 2003 the total outstanding amount of Forward Contracts is US$50.2 million. At the same date, the fair value would represent a favorable valuation for the Company of US$586
thousand.



 In February 2001, Grupo Imsa signed an
agreement with Petroleos Mexicanos (PEMEX) for buying gas at guaranteed price of US$ 4.00 per million of BTUs from January 1st, 2001 to December 31st, 2003.



During the 2003 year Grupo Imsa celebrated hedge agreements to protect the natural gas price at its plants in Mexico and in
the United States of America (USA), including the gas utilized by the Tractebel Plant (see Note 14. b.) for approximately 55% and 70% of their consumption, respectively. The summary of the hedging contracts mentioned before as of December 31, 2003,
is as follows:



|                                |  |                               |  |                                           |  |                           |  |

b. The
carrying amounts of the Companys cash equivalents, accounts receivable, accounts payable and current notes payable approximate fair value because they have relatively short-term maturities and bear interest at rates tied to market indicators,
as appropriate. The Companys long-term debt consists of debt instruments that bear interest at variable rates tied to market indicators and as such the carrying values are not materially different from the estimated fair market values at
December 31, 2003 and 2002, respectively.



|11. | FOREIGN CURRENCY BALANCES AND TRANSACTIONS:
|--- | -------------------------------------------



a. During the years ended December 31, 2003 and 2002, the Mexican peso experienced devaluation with respect to the U.S. dollar of approximately 8%

b. On January 1, 2002, the income tax law enacted no longer allows the deferral of the 5% payment
of taxable income until distribution of related profits. The Mexican income tax rate was 35% in 2002, 34% in 2003, 33% in 2004 and 32% in 2005 and thereafter. The obligation to withhold income tax for dividends paid to individuals or non residents

The deferred income
tax effect from the reduction in 2002 rates related to the gradual reduction explained above, resulted in a recalculation of the deferred income tax liability recorded as of December 31, 2001. The various rates applicable beginning in 2003 were
applied to temporary differences based on their estimated reversal date.



The principal components of deferred income tax as of December 31, 2003 and 2002 are related to Inventories and Fixed Assets.



The change during 2003, 2002 and 2001 of the insufficiency in capital restatement as shown on the statement of changes in stockholders equity, is
presented net of the related effect of deferred income tax, for a total of Ps.(29), Ps.(88) and Ps.604, respectively.



As of December 31, 2003, 2002 and 2001 there are taxable recurring temporary differences related to the deferred employees profit sharing, mainly
due to inventories and fixed assets. The liability from this deferred employees profit sharing has not been recorded because the Company considers that it will not be realized due to the continuity and recurrence of its operations.



d. The effective income tax rate for the year 2003, 2002 and 2001 of
29.9%, 21.6% and 24.7%, respectively, differ from the statutory rate, principally due to the amortization of the excess of fair value over cost of shares acquired and to permanent differences such as nondeductible expenses and the effects of
inflation.



e.The tax on assets paid in excess of
income tax is available as a tax credit carry-forward against future Mexican income taxes for ten years. The tax on assets carry-forward is restated annually using factors derived from the NCPI, in accordance with Mexican tax law.



|14. | COMMITMENTS AND CONTINGENCIES:

Stockholders equity, except restated paidin capital and tax retained earnings, will be subject to an outstanding rate dividend tax, payable by the Company, in the event of distribution. In 2003 such rate was 34%, and will be reduced by
one percentage point each year until reaching 32% in 2005. The Company may credit the tax paid on such distribution in the year that paid or can be carry-forward for two years following such payment.



|16. | BUSINESS SEGMENT DATA:
|--- | ----------------------



The accounting policies of the segments are the same as those described in Notes 2 and 3. The Company evaluates the performance of its segments on the
basis of operating income. Intersegment sales and transfers are accounted for as if the sales and transfers were to third parties, that is, at current market prices.



Grupo Imsas reportable segments are strategic business units that offer different products. The segments are managed
separately; each requires different manufacturing operations, technology and marketing strategies; and each segment primarily serves a different customer base.



The Company is engaged in four business segments in accordance with accounting principles, as follows:



|                                          |  |

|17. | NEW ACCOUNTING PRINCIPLES:
|--- | --------------------------



In March 2003, the IMCP issued Bulletin C-15, Impairment in the Value of Long-Lived Assets and Their Disposal (C-15), whose adoption is
mandatory for fiscal years beginning on or after January 1, 2004, although early adoption is encouraged. C-15 establishes, among other things, new rules for the calculation and recognition of impairment losses for long-lived assets and their
reversal. It also provides guidance as to indicators of potential impairment in the carrying amount of tangible and intangible long-lived assets in use, including goodwill. Companies must test for impairment unless there is conclusive evidence that
the indicators of impairment are temporary. The calculation of such loss requires the determination of the recoverable value, which is now defined as the greater of the net selling price of a cash-generating unit and its value in use, which is the
net present value of discounted future net cash flows. The accounting principles issued prior to this new Bulletin used future net cash flows, without requiring the discounting of such cash flows. Management believes that the adoption of this new
Bulletin as of January 1, 2004, will not have significant effects on the Companys consolidated financial position or results of operations.



In May 2003, the IMCP issued Bulletin C-12, Financial Instruments of a Debt or Equity Nature or a Combination of Both (C-12), whose
application is mandatory for financial statements of periods beginning on or after January 1, 2004, although early adoption is encouraged. C-12 is the compilation of the standards issued by the IMCP with respect to the issue of debt or equity
financial instruments, or a combination of both, and includes additional standards on the accounting recognition for these instruments. Consequently, C-12 indicates the basic differences between liabilities and stockholders equity and
establishes the rules for classifying and valuing the components of debt and equity of combined financial instruments in the initial recognition. Subsequent recognition and valuation of liabilities and stockholders equity of the financial
instruments is subject to the standards issued previously in the applicable bulletins. Management believes that the adoption of this new Bulletin as of January 1, 2004, will not have significant effects on the Companys consolidated financial
position or results of operations.



|18. | SUBSEQUENT EVENT:
|--- | -----------------



In January 2004 IMSALUM acquired the remainder 49% of shares from its subsidiary Louisville Ladder Group, L.L.C. (LLG) for US$15 million. Currently, LLG
is one the most important companies of ladders in the USA and its exports its products to Canada, Central and South America, Europe and Asia.



|19. | DIFFERENCES BETWEEN MEXICAN AND UNITED STATES ACCOUNTING PRINCIPLES:
|--- | --------------------------------------------------------------------



The Companys consolidated financial statements are prepared in accordance with Mexican GAAP, which vary in certain significant respects from
accounting principles generally accepted in the United States of America (U.S. GAAP).



The Mexican GAAP consolidated financial statements include the effects of inflation as provided for under Bulletin B-10, as amended, whereas financial
statements prepared under U.S. GAAP are presented on an historical cost basis. The following reconciliation to U.S. GAAP does not include the reversal of the adjustments required under Bulletin B-10, as amended, except for the reversal of the
restatement of foreign sourced fixed assets (see Note 3.e.). The application of Bulletin B-10, as amended, represents a comprehensive measure of the effects of price level changes in the Mexican economy and, as such, is considered a more meaningful
presentation than historical cost-based financial reporting.



As mentioned in Note 2b, the Company restates prior period consolidated financial statements using a weighted average rate that incorporates the effects of inflation in Mexico for the Companys Mexican operations using



F-21

##### Table of Contents

NCPI and inflation and currency exchange rate fluctuations in countries in which the Company has foreign
subsidiaries (the Restatement Factor). However, because the Restatement Factor used to restate prior period financial statements incorporates the effects of changes in foreign currency exchange rates through the most recent balance sheet date, it is
considered a difference between Mexican GAAP and U.S. GAAP. For purposes of the U.S. GAAP reconciliation, prior period balances are restated only for changes in the NCPI as discussed in Note 19 (f).



In addition, under Mexican GAAP, the Company accounted for certain 50%
owned, jointly controlled operating entities using proportionate consolidation during 2003, 2002 and 2001 (see Note 2.a.). U.S. GAAP requires such investments to be accounted for using the equity method of accounting. The reconciliation of net
income and stockholders equity presented below do not, and are not required to, give effect to this difference between Mexican and U.S. GAAP. Amounts included in the Companys Mexican GAAP financial statements as of December 31, 2003,
2002 and 2001 and for the years then ended under proportionate consolidation are presented below:

The applicable
effects of inflation on the above U.S. GAAP adjustments in the reconciliation of net income which relate to monetary assets or liabilities have been included in the corresponding adjustments. The adjustments considered to be monetary items are
deferred income taxes and deferred employees profit-sharing. For purposes of the reconciliation of stockholders equity, such inflation effects have no impact as the offsetting entry to the monetary gain recorded in the statement of
operations is the (insufficiency) excess in capital restatement which is a component of stockholders equity.



A summary of changes in stockholders equity giving effect to the U.S. GAAP adjustments described above is as follows:

(a) Deferred Income
Taxes and Employees Profit-Sharing



Under Mexican
GAAP, prior to January 1, 2000, deferred taxes were provided only for identifiable, nonrecurring timing differences which were expected to reverse over a definite period of time. Beginning on January 1, 2000, the Company applied the Bulletin D-4.
For U.S. GAAP purposes, the Company applies Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).



Under SFAS 109, deferred tax assets and liabilities are recognized for future tax consequences of temporary differences between the financial statement
carrying amounts of assets and liabilities and their tax bases. Deferred tax assets are also recognized for the estimated future effects of tax loss and asset tax credit carry-forwards. Deferred tax assets are reduced by any tax benefits that are
not expected to be realized.



The Company calculates a
deferred employees profit-sharing liability for U.S. GAAP purposes based on temporary differences between the financial reporting bases and employees profit-sharing bases of assets and liabilities for all of the Companys Mexican
subsidiaries which have employees. Under U.S. GAAP, employee profit-sharing expense would be considered as a component of operating expenses.

##### Table of Contents

The portions of deferred income taxes and deferred employees profit-sharing attributable to the
excess or insufficiency of replacement cost over or under inflation indexed costs has been reflected as an adjustment to the (insufficiency) excess in capital restatement (accumulated other comprehensive loss) in the U.S. GAAP changes in
stockholders equity.

Tax loss
carryforwards, at December 31, 2003, for the Companys Mexican, U.S. and Brazilian operations were Ps 277, Ps 180 and Ps 129 respectively. Such tax loss carryforwards for the Mexican operations and U.S. operations begin expiring in 2010 and
2012, respectively. The tax loss carryforwards in relation to Brazil do not have expiration dates.

Deferred employee
profit sharing decreased and increased to Ps 34 and Ps 208 for the years ended December 31, 2003 and 2002, respectively. In 2002, the Company elected to calculate deferred employee profit sharing by utilizing an alternative method on the basis that
this method is preferable. This alternative method is permitted based on legal proceedings where several Mexican companies sued the tax authorities, based on unconstitutionality, and in 2002 won such judgements against the tax authorities. The
former method required that the historical-tax basis be utilized for the calculation of deferred employee profit sharing and the alternative method allows the tax-indexed basis to be utilized for this calculation. The accumulated effect of the
change is Ps 196 and has been recorded in 2002.



The Company
considers its investments in foreign subsidiaries to be permanently reinvested. At December 31, 2003, unrepatriated earnings in foreign subsidiaries was Ps 224 .

(b) Negative Goodwill



Negative goodwill is recognized under Mexican GAAP and is amortized by the straight-line method over the period the acquired
companies are integrated into the Companys operations. Such amortization period cannot exceed five years.



For purposes of U.S. GAAP, the excess of fair value of net assets acquired over cost of subsidiaries is recorded as a reduction of long-term assets. As
such, the amounts amortized to income as negative goodwill for Mexican GAAP have been reversed and are being amortized over the average estimated remaining lives of the acquired non-current assets.



(c) Financial Instruments



Under U.S. GAAP, the Companys derivative instruments are accounted for
as defined by SFAS No. 133 Accounting for Derivatives Instruments and Hedging Activities which requires that each derivative be stated in the balance sheet at its fair value with gains and losses reflected in the income statement, except
to the extent the derivative qualifies for hedge accounting.



Derivatives that do qualify for hedge accounting under SFAS No. 133 should be recorded where the effective portion of the derivativess gain or loss is initially reported as a component of other comprehensive income (outside earnings)
and subsequently reclassified into earnings when the forecasted transaction affects earnings. SFAS No. 133 further provides specific criteria necessary for a derivative to qualify for hedge accounting and requires the discontinuance, on a
prospective basis, of the accounting effective portion recorded in other comprehensive income for an existing hedge if the designation of the cash flow hedge is removed. Derivates entered into by the Company do not qualify for hedge accounting, as
defined by SFAS No. 133.



(d) Pre-operating Expenses



Until December 31, 2002 Mexican GAAP required
capitalization and amortization of pre-operating expenses. Under U.S. GAAP, these costs are expensed when incurred, and therefore a reconciliation adjustment to the income statement was recorded. Starting January 1, 2003 Mexican GAAP changed to
conform with U.S. GAAP provisions.



(e) Capitalization of
Financing Costs



Integral financing cost (income) is
subject to capitalization under Mexican GAAP, including foreign exchange gains and losses, interest expense and gains and losses from monetary position. For Mexican GAAP, the Company has capitalized portions of such integral financing cost (income)
only related to financings specifically obtained for the construction and installation of fixed assets.



For U.S. GAAP purposes, foreign exchange gains and losses and monetary gains and losses are not capitalizable. Additionally, in the absence of financing
obtained specifically for the construction or installation of fixed assets, interest expense is capitalized at the weighted average rate of all debt during the construction or installation period applied to the construction in progress.
Consequently, for U.S. GAAP reconciliation purposes, foreign exchange gains and losses and monetary gains and losses capitalized have been reversed and treated as income or expense as appropriate, and the related effects of depreciation on the
amounts capitalized have been reversed.



(f) B-15 Effects



Effective January 1, 1998, the Company adopted Bulletin
B-15. Adoption of the new standard changed the factor used to restate prior period consolidated financial statements presented for comparative purposes for the effects of inflation from a rate based solely on the NCPI to a weighted-average rate that
incorporates the effects of inflation in Mexico for the Companys Mexican operations using NCPI, and inflation and currency exchange rate fluctuations in countries in which the Company has foreign subsidiaries (the Restatement
Factor).



However, because the Restatement Factor used
to restate prior period financial statements incorporates the effects of changes in foreign currency exchange rates through the most recent balance sheet date, it is not consistent with Regulation S-X Rule 3-20(e) of the Securities and Exchange
Commission.Therefore, for purposes of the U.S. GAAP reconciliation, prior-period consolidated financial statements are only restated for changes in the NCPI.

##### Table of Contents

The Restatement Factor used by the Company to restate prior period amounts was 1.0678 and the applicable
NCPI factor used for purposes of the U.S. GAAP reconciliation is 1.0391.



(g) Restatement of Foreign Sourced Fixed Assets



Effective January 1, 1997, the Company adopted the Fifth Amendment to Bulletin B-10, which allows foreign sourced fixed assets to be restated for inflation using either of two methodologies. Under the first
methodology, foreign sourced fixed assets are restated by applying Mexican NCPI factors to the original cost of the asset, denominated in pesos. The alternate methodology, which is utilized by the Company, restates foreign sourced fixed assets by
applying the inflation factor of the country of origin to the original cost, denominated in the foreign currency, and then translating such amounts into pesos at the foreign exchange rate in effect at the balance sheet date.



The alternate methodology is not consistent with Rule 3-20 (e) of Regulation
S-X of the U.S. Securities and Exchange Commission. Accordingly, foreign sourced fixed assets have been restated using the Mexican NCPI applied to original cost (the balance of the related assets at December 31, 1996 or historical cost if acquired
thereafter, in pesos, for purposes of the U.S. GAAP reconciliation).



(h) Goodwill and Other Intangible Assets



In
accordance with Mexican GAAP the Excess of Cost Over Fair Value of Net Assets Acquired of Subsidiaries (Goodwill) is restated utilizing factors derived from the NCPI and is amortized on a straight line basis over 20 years.



Effective January 1, 2002, the Company adopted Statement of Financial
Accounting Standards (SFAS No. 142), Goodwill and Other Intangible Assets. SFAS No. 142 requires that goodwill and intangible assets with indefinite lives no longer be amortized, but instead tested for impairment at least annually and
written-down with a charge to operations when the carrying amount exceeds the estimated fair value.



In connection with the transition provisions for adopting the standards the Company performed a transitional impairment test and recorded a loss of Ps 60,
all relating to the automotive batteries and related products segment. The method for determining the fair value of the reporting units was the discounted cash flow method.



Additionally, the Company performed its annual impairment test on December 31, 2003, and found no impairment.



Additionally in accordance with SFAS No. 142, the Company discontinued the
amortization of goodwill effective January 1, 2002. The financial statement impact was to reduce amortization expense by $ 61 and increase net income by $ 62 for the year ended December 31, 2002 compared to the year ended December 31, 2001. A
reconciliation of previously reported net income to the amounts adjusted to exclude goodwill, is as follows:



|                                |  |          |  |          |  |         
|------------------------------- |  | -------- |  | -------- |  | --------
|                                |  | 2003     |  | 2002     |  | 2001    
|Reported net income             |  | Ps 1,110 |  | Ps 1,417 |  | Ps 1,463
|Add back: goodwill amortization |  |         |  |         |  | 62      
|                                |  |          |  |          |  |         
|Adjusted net income             |  | Ps 1,110 |  | Ps 1,417 |  | Ps 1,525
|                                |  |          |  |          |  |         



Basic earnings per
share for adjusted net income, presented above, was Ps .39 Ps 50 and Ps .54 for the years ended December 31, 2003, 2002 and 2001, respectively.



The changes in the carrying amount of goodwill for the years ended December 31, 2002 and 2001 are as follows:



|                                |  |          |  
|------------------------------- |  | -------- | -
|Balance as of December 31, 2001 |  | Ps 1,069 |  
|Goodwill acquired               |  | 99       |  
|Amortization                    |  | (60      | )
|                                |  |          |  
|Balance as of December 31, 2002 |  | 1,108    |  
|Goodwill acquired               |  |         |  
|Impairment losses               |  |         |  
|                                |  |          |  
|Balance as of December 31, 2003 |  | Ps 1,108 |  
|                                |  |          |  



The goodwill acquired
in 2002 and 2001 in the amounts of Ps 99 and Ps 25, respectively, was acquired in relation to the steel and plastic construction products segment (see Note 4).

(i) Minority Interest



Under Mexican GAAP, the minority interest in consolidated subsidiaries is presented as a separate component within the
stockholders equity section in the consolidated balance sheet. For U.S. GAAP purposes, the minority interest is not included in stockholders equity.



(j) Other Differences and Supplemental U.S. GAAP Disclosures



(1) Pension Plan Funds  Additional disclosures required by revised SFAS No. 132, Employers
Disclosure about Pensions and Other Postretirement Benefits, are as follows:



The trust assets consist of fixed income and variable funds, valued at market. As of December 31, 2003 and 2002, the pension plan assets are invested in the following financial instrument:



|               |  |      |   |  |       |  
|-------------- |  | ---- | - |  | ----- | -
|               |  | 2003 |   |  | 2002  |  
|Fixed Rate:    |  | 73   | % |  | 81.59 | %
|Variable Rate: |  | 27   | % |  | 18.41 | %



The contributions to
the pension plan funds by subsidiaries amounted to Ps 16 and Ps 15 at December 31, 2003 and 2002, respectively. The Company estimates that the contributions to the pension plan funds during 2004 will reach Ps 16.



(2) Employees Profit-Sharing Expense - The provision for
employees profit-sharing is classified as a non-operating item in accordance with Mexican GAAP. For U.S. GAAP purposes, such provision is classified as an operating expense.



(3) Plant shutdown and fixed asset write-down  In 2002, the Company recorded an expense relating to the plant
shutdown and fixed asset write-down of Ps 48 and Ps 71, respectively, and such expense is classified as a non-operating item in accordance with Mexican GAAP. For U.S. GAAP purposes, such provision is classified as an operating expense.



(4) Termination of interest rate swap In 2002, the Company
terminated an interest rate swap contract, which related to the early payment of its Senior Notes program whereby the Company recognized a gain of Ps 70 which is classified as a non-operating item in accordance with Mexican GAAP. For U.S. GAAP
purposes, such gain is classified as a part of operating income.



(5)Cash Flow Statement The Company presents its supplemental U.S. GAAP cash flow information exclusive of the effects of inflation. Such information for the years ended December 31, 2003, 2002 and 2001 are presented below:

| | (9) | Recently Issued Accounting Standards
| | --- | ------------------------------------



Beginning January 1, 2002, the Company early adopted the provisions of new Statement of Financial Accounting Standards (SFAS) No. 143,
Accounting for Asset Retirement Obligations (SFAS 143), which addresses financial accounting and reporting for obligations associated with the retirement of long-lived assets that result from the acquisition, construction,
development and (or) the normal operation of long-lived assets, except for certain obligations of leases. SFAS 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred.
When the liability is initially recorded an entity capitalizes the cost by increasing the carrying amount of the related long-lived assets. Over time the liability is accreted to its present value each period, and the capitalized cost is amortized
over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The adoption of SFAS 143 did not have a material impact on the
Companys consolidated financial position, results of operations or cash flows.

In April 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 145,
Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13 and Technical Corrections. SFAS No. 145 rescinds SFAS No. 4, Reporting Gains and Losses from Extinguishments of Debt, and an amendment of that
Statement, SFAS No. 64, Extinguishments of Debt Made to Satisfy Sinking-Fund Requirements, whereby gains and losses from extinguishments of debt are no longer classified as extraordinary items within the income statement unless
considered unusual and infrequent. SFAS No. 145 also rescinds SFAS No. 44, Accounting for Intangible Assets of Motor Carriers. SFAS No. 145 amends SFAS No. 13, Accounting for Leases, to eliminate an inconsistency between the
required accounting for sale-leaseback transactions and the required accounting for certain lease modifications that have economic effects that are similar to sale leaseback transactions. SFAS No. 145 also amends other existing authoritative
pronouncements to make various technical corrections, clarify meanings, or describe their applicability under changed conditions. The provision of SFAS No. 145 related to the rescission of SFAS No. 4 was applied by the Company beginning January 1,
2003. The provision of SFAS No. 145 related to SFAS No. 13 was effective for transactions occurring after May 15, 2002. The adoption of SFAS No. 145 did not have a material impact on the Companys consolidated results of operations, financial
position or cash flows.



The Company adopted the initial
recognition and measurement provisions of FASB Interpretation No. 45, Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others (FIN 45) on a prospective
basis to guarantees issued or modified on or after January 1, 2003. FIN 45 requires that the guarantor recognize, at the inception of certain guarantees, a liability for the fair value of the obligation undertaken in issuing such guarantee.
Effective for financial statement periods ending after December 15, 2002, FIN 45 also required additional disclosure requirements about the guarantors obligations under certain guarantees. The adoption of FIN 45 did not have a material impact
on the Companys consolidated financial position, results of operations or cash flows.



In January 2003, the FASB issued FASB Interpretation No. 46, Consolidation of Variable Interest Entities (FIN 46). In December 2003, FIN 46 was replaced by FASB Interpretation No. 46
(revised December 2003), Consolidation of Variable Interest Entities (FIN 46(R)). FIN 46(R) clarifies the application of Accounting Research Bulletin No. 51, Consolidated Financial Statements, to
certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from
other parties. FIN 46(R) requires an enterprise to consolidate a variable interest entity if that enterprise will absorb a majority of the entitys expected losses, is entitled to receive a majority of the entitys expected residual
returns or both. For investments in variable interest entities formed after December 31, 2003, the Company will be required to apply FIN 46(R) as of January 1, 2004. For investments in variable interest entities formed on or before December 31,
2003, the Company will be required to apply FIN 46(R) in the first annual period beginning after December 15, 2004. The Company does not expect the adoption of FIN 46(R) to have a material impact on its consolidated financial statements.



In April 2003, the FASB issued SFAS No. 149, Amendments of
Statement 133 on Derivative Instruments and Hedging Activities, which amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging
activities under SFAS No. 133 Accounting for Derivative Instruments and Hedging Activities. The changes in SFAS No. 149 improve financial reporting by requiring that contracts with comparable characteristics be accounted for similarly.
SFAS No. 149 was effective for contracts entered into or modified after June 30, 2003, except as stated below, and for hedging relationships designated after or modified after June 30, 2003. All provisions of this statement, except as stated below,
should be applied prospectively. The provisions of SFAS No. 149 that relate to SFAS No. 133 implementation issues that have been effective for fiscal quarters that began prior to June 15, 2003, continue to be applied in accordance with their
respective effective dates. The adoption of SFAS No. 149 did not have a significant impact on its consolidated financial position, results of operations or cash flows.
