report of independent registered public
accounting firm
To the Board of Directors and Shareholders of Research In Motion Limited
We have audited management’s assessment, included in Management’s Discussion and Analysis of Financial Condition
and Results of Operations for the Three Months and Fiscal Year Ended March 3, 2007, that Research In Motion Limited (the
“Company”) maintained effective internal control over financial reporting as of March 3, 2007, based on criteria established in
Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(the “COSO criteria”). 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. Our responsibility is to
express an opinion on management’s assessment and an opinion on the effectiveness of 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, evaluating management’s assessment, testing and evaluating the
design and operating effectiveness of internal control, 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 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 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 conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, management’s assessment that the Company maintained effective internal control over financial reporting
as of March 3, 2007 is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, the Company
maintained, in all material respects, effective internal control over financial reporting as of March 3, 2007, based on the COSO
criteria.
We also have audited, in accordance with Canadian generally accepted auditing standards and the standards of the Public
Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company as at March 3, 2007
and March 4, 2006 and the consolidated statements of operations, shareholders’ equity and cash flows for the years ended
March 3, 2007, March 4, 2006 and February 26, 2005 and our report dated May 14, 2007 expressed an unqualified opinion
thereon.
