REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Shareholders of Raytheon Company:
In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of
equity, and of cash flows present fairly, in all material respects, the financial position of Raytheon Company and its
subsidiaries at December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 2009 in conformity with accounting principles generally accepted in the United
States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2009, based on criteria established in Internal Control—Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s
management is responsible for these financial statements, 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
opinions on these financial statements and on the Company’s internal control over financial reporting based on our
integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable
assurance about whether the financial statements are free of material misstatement and whether effective internal control
over financial reporting was maintained in all material respects. Our audits of the financial statements included
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and evaluating the overall financial statement
presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design
and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our
opinions.
As discussed in Note 7 to the consolidated financial statements, in 2009, the Company changed the manner in which it
accounts for, and discloses noncontrolling interests. Also as discussed in Note 2, in 2009, the Company changed the
manner in which it accounts for business combinations. Also as discussed in Note 12, in 2009, the Company changed the
manner in which it calculates earnings per share. As discussed in Note 12 to the consolidated financial statements, in
2008, the Company changed the manner in which it accounts for obligations associated with certain life insurance
agreements. As discussed in Note 15 to the consolidated financial statements, in 2007, the Company changed the manner
in which it accounts for, and discloses, uncertain tax positions.
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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.
