TEXAS INSTRUMENTS 2006 ANNUAL REPORT 4141
The Board of Directors
Texas Instruments Incorporated
We have audited management’s assessment, included in the accompanying Report by Management on Internal Control over
Financial Reporting, that Texas Instruments Incorporated and subsidiaries maintained effective internal control over financial
reporting as of December 31, 2006, based on criteria established in Internal Control – Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Texas Instruments Incorporated’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 Texas Instruments Incorporated maintained effective internal control over
financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on the COSO criteria. Also, in our
opinion, Texas Instruments Incorporated maintained, in all material respects, effective internal control over financial reporting
as of December 31, 2006, 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 Texas Instruments Incorporated and subsidiaries as of December 31, 2006 and 2005, and
the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the
three years in the period ended December 31, 2006, of Texas Instruments Incorporated and our report dated February 23, 2007,
expressed an unqualified opinion thereon.
