21. Migration from Mexican FRS to International Financial Reporting Standards (IFRS):
The Comision Nacional Bancaria y de Valores (Mexican National Banking and Securities Commission, or CNBV) required companies listed on the Mexican Stock Exchange to adopt
IFRS, such as those issued by the International Accounting Standards Board (IASB), beginning January 1, 2012, which permits its early adoption. Therefore, the accompanying
financial statements are the last statements under Mexican FRS. The Company’s transition date is January 1, 2011. Moreover, the CINIF issued Interpretation INIF 19 in order for
companies disclose the obligation and/or decision to adopt IFRS in the notes to the financial statements, the estimated date of adoption and the estimated effect on the financial
statements.
In order to determine its opening statement of financial position at January 1, 2011 under IFRS, the Company will adjust the amounts previously reported in its financial statements
prepared under Mexican FRS, in conformity with IFRS 1, “First-time adoption of IFRS” (IFRS 1). Management is about to conclude the quantification of the estimated differences
between Mexican FRS and IFRS. The information presented hereinbelow has been prepared in conformity with the IFRS that the Company considers that will be in effect or will be
adopted early at December 31, 2012. The accounting standards that will be applicable at December 31, 2012, including those that are optional, are not precisely known. In addition, the
accounting policies selected by the Company might be modified as a result of changes in the economic environment or in trends in the industry that are observable, subsequent to the
issue of these consolidated financial statements. Accordingly, the information disclosed in this Note is subject to changes.
