The Board of Directors and Shareholders of Wal-Mart Stores, Inc.
We have audited Wal-Mart Stores, Inc.’s internal control over financial
reporting as of January 31, 2010, based on criteria established in Internal
Control — Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (the COSO criteria).
Wal-Mart Stores, Inc’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 to Our Shareholders.”
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 assur-
ance 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 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 prepa-
ration 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 its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in condi-
tions, or that the degree of compliance with the policies or proce-
dures may deteriorate.
In our opinion, Wal-Mart Stores, Inc. maintained, in all material respects,
effective internal control over financial reporting as of January 31, 2010,
based on the COSO criteria.
We also have audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the consolidated
balance sheets of Wal-Mart Stores, Inc. as of January 31, 2010 and 2009,
and related consolidated statements of income, shareholders’ equity
and cash flows for each of the three years in the period ended January 31,
2010 and our report dated March 30, 2010 expressed an unqualified
opinion thereon.
