McKESSON CORPORATION
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Stockholders and Board of Directors of
McKesson Corporation:
We have audited the accompanying consolidated balance sheets of McKesson Corporation and subsidiaries (the “Company”) as of
March 31, 2005 and 2004, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three fiscal
years in the period ended March 31, 2005. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These
consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is
to express an opinion on the financial statements and financial statement schedule based on our audits.
We conducted our audits 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 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 provide a reasonable basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of McKesson
Corporation and subsidiaries at March 31, 2005 and 2004, and the results of their operations and their cash flows for each of the three years in
the period ended March 31, 2005, in conformity with accounting principles generally accepted in the United States of America. Also, in our
opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the
effectiveness of the Company’s internal control over financial reporting as of March 31, 2005, based on the criteria established in Internal
Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated
May 12, 2005 expressed an unqualified opinion on management’s assessment of the effectiveness of the Company’s internal control over
financial reporting and an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
