management’s report on internal control over financial reporting
TO OUR STOCKHOLDERS:
Management of Plantronics, Inc. is responsible for establishing and maintaining adequate internal control
over financial reporting, as defined in Rules 13a-15(f) and 15(d)-15(f) under the Securities Exchange
Act of 1934. Our internal control over financial reporting is 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. Internal control over financial
reporting includes those policies and procedures that:
• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of our Company;
• 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 our Company; and
• provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of our 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. In addition, projections of any evaluation of effectiveness to future periods are subject to
the risk that controls may become inadequate because of changes in conditions and that the degree of
compliance with the policies or procedures may change over time.
We assessed the effectiveness of our internal control over financial reporting as of March 31, 2007. In
making this assessment, our management used the criteria set forth in Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO).
Based on our assessment of internal control over financial reporting, management has concluded that, as
of March 31, 2007 our internal control over financial reporting was effective 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.
Our assessment of the effectiveness of the Company’s internal control over financial reporting as of
March 31, 2007 has been audited by PricewaterhouseCoopers LLP, an independent registered public
accounting firm, whose attestation report on our assessment appears herein.
