Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of
Best Buy Co., Inc.:
We have audited the internal control over financial reporting of Best Buy Co., Inc. and subsidiaries (the ‘‘Company’’) as
of February 26, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee
of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining
effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our
responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
We conducted our audit 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
effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and
evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis
for our opinion.
A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s
principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s
board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts
and expenditures of the company are being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition,
use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or
improper management override of controls, material misstatements due to error or fraud may not be prevented or
detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial
reporting to future periods are subject to the risk that the controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of
February 26, 2011, based on the criteria established in Internal Control — Integrated Framework issued by the Committee
of Sponsoring Organizations of the Treadway Commission.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States), the consolidated financial statements and financial statement schedule as of and for the year ended February 26,
2011 of the Company and our report dated April 25, 2011 expressed an unqualified opinion on those financial
statements and financial statement schedule and included an explanatory paragraph relating to the Company’s change in
its method of accounting for noncontrolling interests with the adoption of Financial Accounting Standards Board
Accounting Standards Codification 810, Consolidation.
