These consolidated financial statementsare the responsibility of the Company’s management. Our responsibility is to express an opinion onthese consolidated financial statements based on our audits. We conducted our audits of thesestatements in accordance with the Standards of the Public Company Accounting Oversight Board(United States). Those standards require that we plan and perform the audit to obtain reasonableassurance about whether the consolidated financial statements are free of material misstatement. Anaudit of consolidated financial statements includes examining, on a test basis, evidence supportingthe amounts and disclosures in the consolidated financial statements, assessing the accountingstandards used and significant estimates made by management, and evaluating the overallconsolidated financial statement presentation. We believe that our audits provide a reasonablebasis for our opinions.MFRS vary in certain significant respects from generally accepted accounting principles in theUnited States of America. Information relating to the nature and effect of such differences ispresented in Note 16 to the above consolidated financial statements.Internal control over financial reportingAlso, in our opinion, management’s assessment, included in “Management’s Report on InternalControl Over Financial Reporting” appearing under Item 15, that the Company maintained effectiveinternal control over financial reporting as of December 31, 2006 based on criteria establishedin *Internal Control-Integrated Framework*issued by the Committee of Sponsoring Organizations ofthe Treadway Commission (COSO), is fairly stated, in all material respects, based on thosecriteria. Furthermore, in our opinion, the Company maintained, in all material respects,effective internal control over financial reporting as of December 31, 2006, based on
 

 
criteria established in *Internal Control-Integrated Framework*issued by the COSO. The Company’smanagement is responsible for maintaining effective internal control over financial reporting andfor its assessment of the effectiveness of internal control over financial reporting. Ourresponsibility is to express opinions on management’s assessment and on the effectiveness of theCompany’s internal control over financial reporting based on our audit. We conducted our audit ofinternal control over financial reporting in accordance with the standards of the Public CompanyAccounting Oversight Board (United States). Those standards require that we plan and perform theaudit to obtain reasonable assurance about whether effective internal control over financialreporting was maintained in all material respects. An audit of internal control over financialreporting includes obtaining an understanding of internal control over financial reporting,evaluating management’s assessment, testing and evaluating the design and operating effectivenessof internal control, and performing such other procedures as we consider necessary in thecircumstances. We believe that our audit provides a reasonable basis for our opinions.A company’s internal control over financial reporting is a process designed to provide reasonableassurance regarding the reliability of financial reporting and the preparation of consolidatedfinancial statements for external purposes in accordance with generally accepted accountingprinciples. A company’s internal control over financial reporting includes those policies andprocedures that (i) pertain to the maintenance of records that, in reasonable detail, accuratelyand fairly reflect the transactions and dispositions of the assets of the company; (ii) providereasonable assurance that transactions are recorded as necessary to permit preparation ofconsolidated financial statements in accordance with generally accepted accounting principles, andthat receipts and expenditures of the company are being made only in accordance with authorizationsof management and directors of the company; and (iii) provide reasonable assurance regardingprevention or timely detection of unauthorized acquisition, use, or disposition of the company’sassets that could have a material effect on the consolidated financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent ordetect misstatements. Also, projections of any evaluation of effectiveness to future periods aresubject to the risk that controls may become inadequate because of changes in conditions, or thatthe degree of compliance with the policies or procedures may deteriorate./s/ PricewaterhouseCoopersMexico City, June 22, 2007
