Grupo Casa Saba, S.A.B. de C.V.:
We have audited the accompanying consolidated balance sheets of Grupo Casa Saba, S.A.B. de C.V. and Subsidiaries (collectively the Group) as of December 31, 2011 and 2010
(restated), and the related consolidated statements of income, changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2011. These
financial statements are the responsibility of the Group’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We did not audit
the consolidated financial statements of Farmacias Ahumada, S.A. and Subsidiaries (FASA) as of December 31, 2010, and for the period from October 3 to December 31, 2010, except that
we audited the adjustments for the correction of errors described in Note 3 a) to the consolidated financial statements. Those statements were audited, before the effects of the
adjustments for the correction of the errors described in Note 3 a), by other auditors whose report was furnished to us, and our opinion, insofar as it relates to the amounts included for
FASA, was based solely on the report of the other auditors. FASA is a Chilean subsidiary acquired on October 3, 2010, which statements reflect total assets and revenues constituting
31 percent and 13 percent, respectively, of the related consolidated totals as of December 31, 2010.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States of America) and with auditing standards generally
accepted in Mexico. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material
misstatement. 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 report
of the other auditors referred to in the first paragraph provide a reasonable basis for our opinion.
At December 31, 2011, the Brazilian subsidiary CSB Drogarias, S.A. (Drogarias) lacked adequate accounting records in connection with the inventories balance in the amount of Ps.
76,000 (thousands of Mexican pesos). We were not able to audit the reasonableness of this value through the use of additional alternative procedures. In addition, Drogarias had
certain contingencies that might result in present obligations that have not been properly quantified, as discussed in Note 20 l) to the financial statements.
