Sales to the U.S. government, principally the DoD, were $16.1 billion in 2005 and $15.0 billion in 2004, representing 74% of total sales in 2005 and 2004.

In its government and defense businesses, the Company acts as a prime contractor or major subcontractor for many different U.S. government programs. A program generally is implemented by the award of individual contracts and subcontracts and is subject to congressional appropriations. Congress generally appropriates funds on a fiscal year basis even though a program may extend for several years. Consequently, programs are often only partially funded initially, and additional funds are committed only as Congress makes further appropriations. U.S. government contracts and subcontracts under a program are subject to termination or adjustment if appropriations for such programs are not available or change. The U.S. government is required to adjust equitably a contract price for additions or reductions in scope or other changes ordered by it.

In addition, U.S. government contracts generally contain provisions permitting termination, in whole or in part, without prior notice at the U.S. government’s convenience as well as termination for default based on performance. Upon termination for convenience, the Company is generally entitled to compensation only for work done and commitments made at the time of termination and will receive some allowance for profit on the work performed. A termination arising out of the Company’s default could expose it to liability and have a negative impact on the Company’s ability to obtain future contracts and orders. Furthermore, on contracts for which the Company is a subcontractor and not the prime contractor, the U.S. government could terminate the prime contract for convenience or otherwise, irrespective of the Company’s performance as a subcontractor. The U.S. government’s right to terminate its contracts for convenience has not had any material adverse effect upon Raytheon’s operations or financial condition in light of its total government and defense business.

The Company’s government and defense business is performed under both cost reimbursement and fixed price prime contracts and subcontracts. Cost reimbursement contracts provide for the reimbursement of allowable costs plus the payment of a fee. These contracts fall into three basic types: (i) cost plus fixed fee contracts which provide for the payment of a fixed fee irrespective of the final cost of performance; (ii) cost plus incentive fee contracts which provide for increases or decreases in the fee, within specified limits, based upon actual results as compared to contractual targets relating to such factors as cost, performance and delivery schedule; and (iii) cost plus award fee contracts which provide for the payment of an award fee determined at the discretion of the customer based upon the performance of the contractor against pre-established criteria. Under cost reimbursement type contracts, Raytheon is reimbursed periodically for allowable costs and is paid a portion of the fee based on contract progress. Some costs incident to performing contracts have been made partially or wholly unallowable for reimbursement by statute or regulation. Examples are charitable contributions, certain merger and acquisition costs, lobbying costs and certain litigation defense costs.

The Company’s fixed-price contracts are either firm fixed-price contracts or fixed-price incentive contracts. Under firm fixed-price contracts, Raytheon agrees to perform a specific scope of work for a fixed price and as a result, benefits from cost savings and carries the burden of cost overruns. Under fixed-price incentive contracts, Raytheon shares with the U.S. government savings accrued from contracts performed for less than target costs and costs incurred in excess of targets up to a negotiated ceiling price (which is higher than the target cost) and carries the entire burden of costs exceeding the negotiated ceiling price. Accordingly, under such incentive contracts, the Company’s profit may also be adjusted up or down depending upon whether specified performance objectives are met. Under firm fixed-price and fixed-price incentive type contracts, the Company usually receives either milestone payments equaling 90% of the contract price or monthly progress payments from the U.S. government generally in amounts equaling 80% of costs incurred under government contracts. The remaining amount, including profits or incentive fees, is billed upon delivery and acceptance of end items under the contract.

As a U.S. government contractor, the Company is subject to specific import and export, procurement and other regulations and requirements. Failure to comply with these regulations and requirements could result in reductions of the value of contracts, contract modifications or termination, and the assessment of penalties and fines and lead to suspension or debarment, for cause, from government contracting or subcontracting for a period of time. Among the causes for debarment are violations of various statutes, including those related to procurement integrity, export control, government security regulations, employment practices, the protection of the environment, accuracy of records and recording of costs. Under many U.S. government contracts, the Company is required to maintain facility and personnel security clearances complying with DoD requirements.

The Company is also subject to routine audits and investigations by U.S. government agencies such as the Defense Contract Audit Agency (DCAA). These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. The DCAA also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. If an audit uncovers improper or illegal activities, the Company may be subject to civil and criminal penalties and administrative sanctions, which may include: termination of contracts; forfeiture of profits; suspension of payments; fines; and suspension or prohibition from doing business with the U.S. government.

The Company, principally through its IIS and SAS business segments, is also involved in government programs which are classified by the U.S. government and cannot be specifically described in this Form 10-K. The operating results of these classified programs are included in the Company’s consolidated financial statements. The business risks and considerations associated with these classified programs generally do not differ materially from those of the Company’s other government programs and products.

The Company is subject to similar government regulations and contract requirements with respect to its sales to non-U.S. customers. See “International Sales” on page 12 of this Form 10-K for more information regarding the Company’s sales outside of the U.S.

Because it is engaged in supplying defense-related equipment to the U.S. government, Raytheon is subject to certain business risks, some of which are peculiar to that industry. Among these are: the cost of obtaining and retaining trained and skilled employees; the uncertainty and instability of prices for raw materials and supplies; the problems associated with advanced designs, which may result in unforeseen technological difficulties and cost overruns; and the intense competition and the constant necessity for improvement in facilities and personnel training. Raytheon’s sales to the U.S. government may be affected by changes in procurement policies, budget considerations, changing concepts of national defense, political developments abroad and other factors. See Item 1A “Risk Factors” and “Overview” within Item 7 of this Form 10-K for a description of additional business risks.

See “Sales to the U.S. Government” on page 9 of this Form 10-K for information regarding the percentage of the Company’s revenues generated from sales to the U.S. government.

The Company’s backlog of orders was $34.4 billion at December 31, 2005 and $32.5 billion at December 31, 2004. The 2005 amount includes backlog of approximately $27.2 billion from the U.S. government compared with $25.5 billion at the end of 2004. Approximately $3.6 billion and $1.2 billion of the 2005 backlog amount represents direct foreign government backlog and non-government foreign backlog, respectively. Approximately $19.1 billion of the 2005 year-end backlog is not expected to be filled during the following twelve months. These amounts include both funded backlog (unfilled firm orders for products for which funding has been both authorized and appropriated) and unfunded backlog (firm orders for which funding has not yet been appropriated). For additional information related to backlog figures, see “Segment Results” within Item 7 of this Form 10-K.

Raytheon conducts extensive research and development activities to continually enhance its existing products and services and develop new products and services to meet its customer’s changing needs and requirements. During 2005, Raytheon expended $503 million on research and development efforts compared with $491 million in 2004 and $487 million in 2003. These expenditures principally have been for product development for the U.S. government and for aircraft products, including bid and proposal efforts related to government programs. Raytheon also conducts funded research and development activities under government contracts which are included in net sales. For additional information related to research and development activities, see “Note A—Accounting Policies” within Item 8 of this Form 10-K.

Raytheon is dependent upon the delivery of materials by suppliers and the assembly of major components and subsystems by subcontractors used in the Company’s products. Some products require relatively scarce raw materials. In addition, in connection with its government and defense business, the Company must comply with specific procurement requirements which may, in effect, limit the suppliers and subcontractors the Company may utilize. In some instances, for a variety of reasons, the Company is dependent on sole-source suppliers. The Company enters into long-term or volume purchase agreements with certain suppliers and takes other actions to ensure the availability of needed materials, components and subsystems. In the case of Raytheon Aircraft Company (RAC), RAC is dependent on the successful performance of its suppliers under international supply contracts for the production of certain aircraft and spare parts. Raytheon generally has not experienced material difficulties in procuring the necessary raw materials, components and other supplies for its products. However, the Company has been notified by certain suppliers that they supplied parts which may not comply with certain procurement requirements applicable to DoD contractors. The Company understands that other DoD contractors are experiencing similar potential supply issues. Management does not expect the effects of this potential supply issue to be material.

In recent years, the Company’s revenues in the second half of the year have generally exceeded revenues in the first half. The timing of government awards, the availability of government funding and product deliveries are among the factors affecting the periods in which revenues are recorded. Management expects this trend to continue in 2006.

The Company’s government and defense businesses directly participate in most major areas of development in the defense and government electronics, space, information technology, technical services and special mission aircraft markets. Technical superiority and reputation, price, past performance, delivery schedules, financing, and reliability are among the principal competitive factors considered by customers in these markets. Raytheon competes worldwide with a number of U.S. and international companies in these markets, some of which may have more extensive or more specialized engineering, manufacturing and marketing capabilities than Raytheon does in some areas. The on-going consolidation of the U.S. and global defense, space and aerospace industries continues to intensify competition. Consolidation among U.S. defense, space and aerospace companies has resulted in a reduction in the number of principal prime contractors. As a result of this consolidation, the Company frequently partners on various programs with its major suppliers, some of whom are, from time to time, competitors on other programs.

The Aircraft segment competes primarily with four other companies in the business aviation industry. The principal factors for competition in the industry are price, financing, operating costs, product quality and reliability, cabin size and comfort, travel range and speed, and product service and support.

Raytheon and its subsidiaries own an intellectual property portfolio which includes, by way of example, many United States and foreign patents, as well as unpatented know-how, trademarks and copyrights, all of which contribute to the preservation of the Company’s competitive position in the market. In certain instances, the Company has augmented its technology base by licensing the proprietary intellectual property of others. The Company also licenses its intellectual property to others. While the Company’s intellectual property rights in the aggregate are important to the operation of the Company, the Company does not believe that any existing patent, license or other intellectual property right is of such importance that its loss or termination would have a material adverse effect on the business of the Company, taken as a whole.

As of December 31, 2005, Raytheon had approximately 80,000 employees compared with approximately 79,000 employees at the end of 2004. The increase is primarily due to overall business growth in multiple market sectors and on multiple programs during 2005. Raytheon considers its union-management relationships to be generally satisfactory. In 2005, there were no work stoppages at any of the Company’s sites.

Raytheon’s sales to customers outside the U.S. (including foreign military sales) were $4.2 billion or 19% of total sales in 2005, $3.7 billion or 18% of total sales in 2004, and $3.5 billion or 19% of total sales in 2003. These sales were principally in the fields of air defense systems, air traffic control systems, sonar systems, aircraft products, electronic equipment, computer software and systems, personnel training, equipment maintenance and microwave communication. Foreign subsidiary working capital requirements generally are financed in the countries concerned. Sales and income from international operations and investments are subject to changes in currency values, domestic and foreign government policies (including requirements to expend a portion of program funds in-country) and regulations, embargoes and international hostilities. Exchange restrictions imposed by various countries could restrict the transfer of funds between countries and between Raytheon and its subsidiaries. Raytheon has acted to protect itself against most undue risks through insurance, foreign exchange contracts, contract provisions, government guarantees or progress payments. See revenues derived from external customers and long-lived assets by geographical areas set forth in “Note O—Business Segment Reporting” within Item 8 of this Form 10-K.

Raytheon utilizes the services of sales representatives and distributors in connection with certain foreign sales. Normally representatives are paid commissions and distributors are granted resale discounts in return for services rendered.

The export from the U.S. of many of Raytheon’s products may require the issuance of a license by the U.S. Department of State under the Arms Export Control Act of 1976 (formerly the Foreign Military Sales Act); or by the U.S. Department of Commerce under the Export Administration Act and its implementing regulations as kept in force by the International Emergency Economic Powers Act of 1977 (“IEEPA”); or by the U.S. Department of the Treasury under IEEPA or the Trading with the Enemy Act of 1917. Such licenses may be denied for reasons of U.S. national security or foreign policy. In the case of certain exports of defense equipment and services, the Department of State must notify Congress at least 15 or 30 days (depending on the identity of the country that will utilize the equipment and services) prior to authorizing such exports. During that time, the Congress may take action to block a proposed export by joint resolution which is subject to Presidential veto.

Additional information regarding the risks associated with the Company’s international business is contained in Item 1A “Risk Factors” of this Form 10-K.

The Company’s operations are subject to and affected by a variety of federal, state and local environmental protection laws and regulations. The Company has provided for the estimated cost to complete remediation where the Company has determined that it is probable that the Company will incur such costs in the future to address the environmental impact

at current or formerly owned operating facilities or at sites where it has been named a Potentially Responsible Party (PRP) by the Environmental Protection Agency or similarly designated by other environmental agencies. It is difficult to estimate the timing and ultimate amount of environmental cleanup costs to be incurred in the future due to the uncertainties regarding the extent of the required cleanup and the status of the law, regulations, and their interpretations.

In order to assess the potential impact on the Company’s financial statements, management estimates the possible remediation costs that reasonably could be incurred by the Company. Such estimates take into consideration the professional judgment of the Company’s environmental professionals and, when necessary, consultation with outside environmental specialists.

If the Company is ultimately found to have liability at those sites where it has been designated a PRP, the Company expects that the actual costs of remediation will be shared with other liable PRPs. Generally, PRPs that are ultimately determined to be responsible parties are strictly liable for site clean-up and usually agree among themselves to share, on an allocated basis, the costs and expenses for investigation and remediation of hazardous materials. Under existing environmental laws, however, responsible parties may be jointly and severally liable and, therefore, potentially liable for the full cost of funding such remediation. In the unlikely event that the Company is required to fund the entire cost of such remediation, the statutory framework provides that the Company may pursue rights of contribution from the other PRPs. The amounts the Company records do not reflect the fact that it may recover some of the environmental costs the Company has incurred through insurance or from other PRPs as recovery is not deemed probable.

The Company manages various government-owned facilities on behalf of the government. At such facilities, environmental compliance and remediation costs have historically been the responsibility of the government and the Company relied (and continues to rely with respect to past practices) upon government funding to pay such costs. While the government remains responsible for capital and operating costs associated with environmental compliance, responsibility for fines and penalties associated with environmental noncompliance, are typically borne by either the government or the contractor, depending on the contract and the relevant facts. Fines and penalties are unallowable costs under the contracts pursuant to which such facilities are managed.

Most of the laws governing environmental matters include criminal provisions. If the Company were convicted of a violation of the Federal Clean Air Act or the Clean Water Act, the facility or facilities involved in the violation would be placed by the EPA on the “Excluded Parties List” maintained by the Government Services Administration. The listing would continue until the EPA concluded that the cause of the violation had been cured. Listed facilities cannot be used in performing any U.S. government contract awarded during any period of listing by the EPA.

Additional information regarding the effect of compliance with environmental protection requirements and the resolution of environmental claims against the Company and its operations is contained in Item 1A “Risk Factors,” Item 3 “Legal Proceedings,” “Commitments and Contingencies” within Item 7 and “Note L—Commitments and Contingencies” within Item 8 of this Form 10-K.

We expressly disclaim any obligation or intention to provide updates to the forward-looking statements and the estimates and assumptions associated with them.

We depend on the U.S. government for a significant portion of our sales, and the impairment of this relationship or changes in government defense spending could have severe consequences on our business.

Approximately 74% of our net sales in 2005 were to the U.S. government. Therefore, any significant disruption or deterioration of our relationship with the U.S. government could adversely affect our current government contracts and our ability to procure new government contracts, which could significantly reduce our revenues and negatively impact our financial condition and operations. We compete with other government contractors for a limited number of government programs and for uncertain levels of funding. Our competitors continuously engage in efforts to expand their business relationships with the U.S. government at our expense. Accordingly, despite our efforts to maintain and broaden our relationships with it, the U.S. government may choose to use other contractors for its limited number of programs.

In addition, our revenues from the U.S. government largely result from contracts awarded under various defense programs. The funding of our programs is subject to the overall U.S. government budget and appropriation decisions and processes and our programs must compete for funding with non-defense programs and other defense programs in which we are not involved. U.S. government budget decisions, including defense spending, are based on changing government priorities and objectives, which are driven by numerous factors, including geo-political events and macroeconomic conditions, and are beyond our control. In recent years, the overall level of U.S. defense spending has increased for numerous reasons, including increases in funding of operations in Iraq and Afghanistan and the U.S. Department of Defense’s military transformation initiatives. We can give no assurance that U.S. defense spending will continue to grow. Significant changes to U.S. defense spending could have long-term consequences for our size and structure. In addition, as a result of changing government priorities and requirements, defense spending could shift away from certain programs to other programs or into new areas and the timing of funding of certain programs could change. Shifts or reductions in defense spending or changes in timing could result in the reduction or elimination of, or the delay in, funding of one or more of our defense programs, which could negatively impact our results of operations and financial condition.

A substantial majority of our business is governed by U.S. government contracts, which are subject to continued appropriations by Congress and termination.

In our government and defense businesses, we act as a prime contractor or major subcontractor for many different U.S. government programs. A program generally is implemented by the award of individual contracts and subcontracts and is subject to congressional appropriations. Congress generally appropriates funds on a fiscal year basis even though a program may extend for several years. Consequently, programs are often only partially funded initially, and additional funds are committed only as Congress makes further appropriations. U.S. government contracts and subcontracts under a program are subject to termination or adjustment if appropriations for such program are not available or change.

In addition, our government contracts typically involve the development, application and manufacturing of advanced defense and technology systems and products aimed at achieving challenging goals. New technologies may be untested or unproven. In some instances, product requirements or specifications may be modified. As a result, we may experience technological and other performance difficulties, which may result in delays, setbacks, cost overruns and product failures, in connection with our government contracts.

Our financial performance is highly dependent on our procurement, performance and payment under our U.S. government contracts. While we are involved in numerous programs and are parties to thousands of U.S. government contracts, the termination of one or more large contracts, whether due to lack of funding, for convenience, or otherwise, or the occurrence of delays, cost overruns and product failures in connection with one or more large contracts, could negatively impact our results of operations and financial condition. Furthermore, we can give no assurance that we would be able to procure new U.S. government contracts to offset the revenues lost as a result of any termination of our contracts.

We derive a significant portion of our revenues from international sales and are subject to the risks of doing business in foreign countries.

In 2005, sales to non-U.S. customers, including foreign military sales, accounted for approximately 19% of our net sales. We expect that international sales will continue to account for a significant portion of our revenues for the foreseeable future. As a result, we are subject to risks of doing business internationally, including:

While these factors or the impact of these factors are difficult to predict, any one or more of these factors could negatively impact our results of operations and financial condition.

We may not be successful in obtaining the necessary licenses to conduct operations abroad, and Congress may prevent proposed sales to foreign governments.

In order to sell many of our products outside of the U.S., we must first obtain licenses and authorizations from various government agencies. For certain sales of defense equipment and services to foreign governments, the U.S. Department of State must notify Congress at least 15 to 30 days, depending on the size and location of the sale, prior to authorizing these sales. During that time, Congress may take action to block the proposed sale. We can give no assurance that we will continue to be successful in obtaining the necessary licenses or authorizations or that Congress will not prevent certain sales. Our inability to sell products outside of the U.S. could negatively impact our results of operations and financial condition.

Competition within our markets may reduce our procurement of future contracts and our sales.

We operate in highly competitive markets. Our competitors range from highly resourceful small concerns, which engineer and produce specialized items, to large, diversified firms. Several established and emerging companies offer a variety of products for applications similar to those of our products. Our competitors may have more extensive or more specialized engineering, manufacturing and marketing capabilities than we do in some areas. In addition, as the defense industry consolidates, companies may enhance their competitive position and ability to compete against us. We are also facing increasing competition in our domestic and international markets from foreign and multinational firms.

Some of our largest customers could develop the capability to manufacture products similar to products that we manufacture and provide services similar to services we offer. This would result in these customers supplying their own products or services and competing directly with us for sales of these products or services, all of which could significantly reduce our revenues and negatively impact our operations and financial results.

Accordingly, if we are unable to continue to compete successfully against our current or future competitors, we may experience declines in revenues and market share which could negatively impact our results of operations and financial condition.

Our future success depends on our ability to develop new offerings and technologies that achieve market acceptance.

The markets in which we operate are characterized by rapidly changing technologies and evolving industry standards. Accordingly, our future performance depends on a number of factors, including our ability to:

Specifically, at Raytheon Aircraft Company (RAC), our future success is dependent on our ability to meet scheduled timetables for the development, certification and delivery of new and derivative product offerings and our ability to continue to compete using our existing legacy aircraft products.

We believe that, in order to remain competitive in the future, we will need to continue to invest significant financial resources to develop new products, services and technologies. These expenditures could divert our attention and resources from other projects, and we cannot be sure that these expenditures will ultimately lead to the timely development of new technology. Due to the design complexity of our products, we may in the future experience delays in completing the development and introduction of new products. Any delays could result in increased costs of development or deflect resources from other projects. In addition, there can be no assurance that the market for our offerings will develop or continue to expand as we currently anticipate. The failure of our technology to gain market acceptance could significantly reduce our revenues and harm our business. Furthermore, we cannot be sure that our competitors will not develop competing technologies which gain market acceptance in advance of our products. The possibility that our competitors might develop new technology or offerings might cause our existing technology and offerings to become obsolete. If we fail in our new product development efforts or our products or services fail to achieve market acceptance more rapidly than our competitors, our ability to procure new government contracts could be negatively impacted, which would negatively impact our business, results of operations and financial condition.

We enter into fixed-price contracts which could subject us to losses in the event that we have cost overruns.

A significant portion of our contracts are entered into on a fixed-price basis. This allows us to benefit from cost savings, but we carry the burden of cost overruns. Because many of our contracts involve advanced designs and innovative technologies, we may experience unforeseen technological difficulties and cost overruns. If our initial estimates are incorrect, we can lose money on these contracts. In addition, some of our contracts have provisions relating to cost controls and audit rights, and if we fail to meet the terms specified in those contracts then we may not realize their full benefits. Lower earnings caused by cost overruns and cost controls would have a negative impact on our results of operations.

Our business could be adversely affected by a negative audit by the U.S. government.

As a government contractor, we are subject to routine audits and investigations by U.S. government agencies such as the Defense Contract Audit Agency (DCAA). These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. The DCAA also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. If an audit uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, which may include: termination of contracts; forfeiture of profits; suspension of payments; fines; and suspension or prohibition from doing business with the U.S. government. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us.

As a U.S. government contractor, we are subject to a number of procurement rules and regulation.

Government contractors must also comply with specific procurement regulations and other requirements. These requirements, although customary in government contracts, increase our performance and compliance costs. If these requirements change, our costs of complying with them could increase and reduce our margins. In addition, failure to comply with these regulations and requirements could result in reductions of the value of contracts, contract modifications or termination, and the assessment of penalties and fines, which could negatively impact our results of operations and financial condition. Our failure to comply with these regulations and requirements could also lead to suspension or debarment, for cause, from government contracting or subcontracting for a period of time. Among the causes for debarment are violations of various statutes, including those related to:

The termination of a government contract or relationship as a result of any of these acts could have a negative impact on our results of operations and financial condition and could have a negative impact on our reputation and ability to procure other government contracts in the future.

We depend on component availability, subcontractor performance and our key suppliers to manufacture and deliver our products and services.

We are dependent upon the delivery of materials by suppliers and the assembly of major components and subsystems by subcontractors used in our products in a timely and satisfactory manner and in full compliance with applicable terms and conditions. In our government and defense businesses, we must comply with specific procurement requirements, which may, in effect, limit the suppliers and subcontractors we may utilize. In some instances, we are dependent on sole-source suppliers. If any of these suppliers or subcontractors fails to meet our needs, we may not have readily available alternatives. While we enter into long-term or volume purchase agreements with certain suppliers and take other actions to ensure the availability of needed materials, components, and subsystems, we cannot be sure that such items will be available in the quantities we require, if at all. If we experience a material supplier or subcontractor problem, our ability to satisfactorily and timely complete our customer obligations could be negatively impacted which could result in reduced sales, termination of contracts and damage to our reputation and relationships with our customers. We could also incur additional costs in addressing such a problem. Any of these events could have a negative impact on our results of operations and financial condition.

We use estimates in accounting for many of our programs and our new commercial aircraft and changes in our estimates could adversely affect our future financial results.

Contract accounting requires judgment relative to assessing risks, including risks associated with customer directed delays and reductions in scheduled deliveries, unfavorable resolutions of claims and contractual matters, judgments associated with estimating contract revenues and costs, and assumptions for schedule and technical issues. Due to the size and nature of many of our contracts, the estimation of total revenues and cost at completion is complicated and subject to many variables. For example, we must make assumptions regarding the length of time to complete the contract because costs also include expected increases in wages and prices for materials; consider incentives or penalties related to performance on contracts in estimating sales and profit rates, and record them when there is sufficient information for us to assess anticipated performance; and use estimates of award fees in estimating sales and profit rates based on actual and anticipated awards.

In addition, we use lot accounting for our new commercial aircraft such as the Beechcraft Premier I and the Hawker 4000. Lot accounting involves selecting an initial lot size at the time a new aircraft begins to be delivered and measuring an average margin over the entire lot for each aircraft sold. The costs attributed to aircraft delivered are based on the estimated average margin of all aircraft in the lot and are determined under the learning curve concept which anticipates a predictable decrease in unit costs from cost reduction initiatives and as tasks and production techniques become more efficient through repetition. Once the initial lot has been completed, the use of lot accounting is discontinued. Accordingly, the selection of lot size is a critical judgment. We determine lot size based on several factors, including the size of firm backlog, the expected annual production on the aircraft, and the anticipated market demand for the product.

Because of the significance of the judgments and estimation processes described above, it is likely that materially different amounts could be recorded if we used different assumptions, including our ability to sell at least the number of aircraft included in the initial lot size, or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may adversely affect our future results of operations and financial condition.

We must assess the value of used aircraft and aircraft materials and parts which requires significant judgment, and changes in the value of such items could adversely affect our future financial results.

The valuation of used aircraft in inventories, which are stated at cost, but not in excess of realizable value, requires significant judgment. The valuation of used aircraft is also considered in assessing the realizable value of certain commuter aircraft-related assets which serve as collateral for the underlying financing arrangements. As part of our assessment of realizable value, we evaluate many factors, including current and future market conditions, the age and condition of the aircraft, and availability levels for the aircraft in the market. In addition, the valuation of aircraft materials and parts that support our worldwide fleet of aircraft, which are stated at cost, but not in excess of realizable value, also requires significant judgment. As part of our assessment of realizable value, we evaluate many factors, including the expected useful life of the aircraft, some of which have remained in service for up to 50 years. Furthermore, we assumed an orderly disposition of both used aircraft and aircraft materials and parts in connection with our assessments of realizable value. Changes in market or economic conditions and changes in products or competitive products may adversely impact the future valuation of used aircraft and aircraft materials and parts and such change in valuation could negatively impact our future financial condition and results of operations.

Goodwill and other intangible assets represent a significant portion of our assets and any impairment of these assets could negatively impact our results of operation.

At December 31, 2005, we had goodwill and other intangible assets of approximately $12.1 billion, net of accumulated amortization, which represented approximately 50% of our total assets. Our goodwill is subject to an impairment test on an annual basis and is also tested whenever events and circumstances indicate that goodwill may be impaired. Any excess goodwill carrying value resulting from the impairment test must be written off in the period of determination. Intangible assets (other than goodwill) are generally amortized over a one to five-year period. In addition, we will continue to incur non-cash charges in connection with the amortization of our intangible assets other than goodwill over the remaining

useful lives of such assets. Future determinations of significant write-offs of goodwill as a result of an impairment test or any accelerated amortization of other intangible assets could have a negative impact on our results of operations and financial condition.

Our results of operations and financial condition could be adversely affected by a downturn in the general aviation and other aircraft markets.

If there is a downturn in the general aviation and other aircraft markets due to declining general economic conditions or other reasons, our results of operations and financial condition could be negatively impacted. RAC could experience declining sales of aircraft and increases in aircraft inventories and costs. RAC provides long-term financing to its customers, so it could also experience an increase in defaults under these financing arrangements.

In such a downturn, Flight Options LLC (FO) could also experience declining sales of fractional ownership services and incur greater losses, which could result in the Company’s investment in FO becoming further impaired and the Company incurring additional charges.

In addition, Raytheon Airline Aviation Services LLC (RAAS) has exposure to outstanding financial arrangements for commuter aircraft, with the aircraft serving as collateral under these arrangements. RAAS commuter aircraft customers are generally thinly capitalized companies whose financial condition could be significantly affected by sustained higher fuel costs, industry consolidation, and declining commercial aviation market conditions. As a result, RAAS could experience an increase in financial defaults by its aircraft customers.

We are at risk of losses and adverse publicity stemming from any accident involving aircraft for which we hold design authority.

If a Raytheon aircraft were to crash or be involved in an accident, we could be exposed to significant tort liability. Our insurance may be inadequate to cover damages arising from any future accidents. In the event that our insurance is not adequate, we may be forced to bear substantial losses from an accident. In addition, any accident involving a Raytheon aircraft could create a public perception that our aircraft are not safe or reliable, which could harm our reputation, result in reduced sales, and harm our business.

Furthermore, accidents and incidents involving Raytheon aircraft may prompt the Federal Aviation Administration (FAA) to issue directives or other notices regarding the aircraft. Publication of a FAA directive or notice could create a public perception that a particular Raytheon aircraft is not safe, reliable, or suitable for an operator’s needs. This perception could result in a claim being filed against us or lost future sales, or both. In addition, the FAA could require design modifications causing us to incur significant expenditures altering an aircraft design, altering aircraft in production, and altering fielded aircraft under warranty. FAA airworthiness directives are typically followed by similar regulatory requirements in other countries where affected aircraft are certified. The publication of any of the foregoing by the FAA could lead to a decline in revenues and have a negative impact on our business, financial condition and results of operations.

The aircraft manufacturing industry is subject to extensive government regulation, and changes in such regulations may increase our operating costs.

Our commercial aircraft products are required to comply with numerous regulations governing design approvals, production and quality systems, airworthiness, and continuing operational safety in the U.S. and other countries in which our aircraft are sold. These requirements are administered by the FAA in the United States and the aviation authorities of other countries, including, in the case of Europe, the European Aviation Safety Agency (EASA). If these requirements change, our costs of complying with them could increase and reduce our margins.

We use estimates in accounting for our pension plan and changes in our estimates could adversely affect our results of operations.

We must determine our pension plan expense or income which involves significant judgment, particularly with respect to our long-term return on pension assets and discount rate assumptions. If our discount rate assumption (which is used to determine the present value of our benefit obligations) is decreased due to changes in our assumptions or other reasons, our pension plan expense could increase which would negatively impact our results of operations.

We have entered, and expect to continue to enter, into joint venture, teaming and other arrangements, and these activities involve risks and uncertainties.

In the ordinary course of our business, we have entered, and expect to continue to enter, into certain joint venture, teaming and other business relationships to, among other things, expand our research and development, sales and other capabilities and support our broad portfolio of products and services. In some of these business arrangements, we may partner with one or more competitors. Some arrangements may involve foreign partners. These arrangements involve certain risks and uncertainties, including:

We have made, and expect to continue to make, strategic acquisitions and investments, and these activities involve risks and uncertainties.

We have completed a number of acquisitions and investments over the past several years, and we currently intend to do so in the future. Acquisitions and investments involve certain risks and uncertainties, including the difficulty in integrating newly-acquired businesses, the challenges in achieving strategic objectives and other benefits expected from acquisitions or investments, the potential impairment of acquired assets, and the potential loss of key employees of the acquired businesses.

We may incur additional charges relating to our former Engineering and Construction Business.

We have obligations related to outstanding letters of credit, surety bonds and guarantees (“Support Agreements”) provided in connection with a number of contracts and leases of our former engineering and construction business unit, which we sold to Washington Group International in July 2000. In meeting our obligations under the remaining Support Agreements, we have various risks and exposures, including warranty closeout, various liquidated damages issues, and potential adverse claims resolution. While these potential obligations, liabilities and risks or the impact of them may be difficult to predict, they could have a negative impact on our financial condition and results of operations.

The outcome of litigation in which we have been named as a defendant is unpredictable and an adverse decision in any such matter could have a material adverse effect on our financial position, results of operations, and liquidity.

We are defendants in a number of litigation matters and are subject to various other claims, demands and investigations. These matters may divert financial and management resources that would otherwise be used to benefit our operations. Although we believe that we have meritorious defenses to the claims made in the litigation matters to which we have been named a party, and intend to contest each lawsuit vigorously, no assurances can be given that the results of these matters will be favorable to us. An adverse resolution or outcome of any of these lawsuits, claims, demands or investigations could have a negative impact on our financial condition, results of operations, and liquidity.

We depend on the recruitment and retention of qualified personnel, and our failure to attract and retain such personnel could seriously harm our business.

Due to the specialized nature of our businesses, our future performance is highly dependent upon the continued services of our key engineering personnel and executive officers, the development of additional management personnel and the hiring of new qualified engineering, manufacturing, marketing, sales and management personnel for our operations. Competition for personnel is intense, and we may not be successful in attracting or retaining qualified personnel. In addition, certain personnel may be required to receive security clearance and substantial training in order to work on certain programs or perform certain tasks. The loss of key employees, our inability to attract new qualified employees or adequately train employees, or the delay in hiring key personnel could seriously harm our business, results of operations and financial condition.

Some of our workforce is represented by labor unions so our business could be harmed in the event of a prolonged work stoppage.

Approximately 11,500 of our employees are unionized, which represented approximately 15% of our employees at December 31, 2005. As a result, we may experience work stoppages, which could adversely affect our business. We cannot predict how stable our union relationships, currently with 9 different U.S. labor organizations and 4 different non-U.S. labor organizations, will be or whether we will be able to successfully negotiate successor agreements without impacting our financial condition. In addition, the presence of unions may limit our flexibility in dealing with our workforce. Work stoppages could negatively impact our ability to manufacture our products on a timely basis, which could negatively impact our results of operations and financial condition.

We may be unable to adequately protect our intellectual property rights, which could affect our ability to compete.

We own many United States and foreign patents and patent applications, and have rights in unpatented know-how, trademarks, and copyrights. On occasion, we have applied for semiconductor chip mask work registrations. The U.S. government has licenses in our patents and certain other intellectual property that are developed in performance of government contracts, and it may use or authorize others to use such patents and intellectual property for government purposes. There can be no assurance that any of our patents and other intellectual property will not be challenged, invalidated or circumvented by third parties. In some instances, we have augmented our technology base by licensing the proprietary intellectual property of others. In the future, we may not be able to obtain necessary licenses on commercially reasonable terms. We enter into confidentiality and invention assignment agreements with our employees, and enter into non-disclosure agreements with our suppliers and appropriate customers so as to limit access to and disclosure of our proprietary information. These measures may not suffice to deter misappropriation or independent third party development of similar technologies. Moreover, the protection provided to our intellectual property by the laws and courts of foreign nations may not be as advantageous to us as the remedies available under United States law.

Our operations expose us to the risk of material environmental liabilities.

We use and generate large quantities of hazardous substances and wastes in our manufacturing operations. As a result, we are subject to potentially material liabilities related to personal injuries or property damages that may be caused by hazardous substance releases and exposures. For example, we are investigating and remediating contamination related to our current or past practices at numerous properties and, in some cases, have been named as a defendant in related personal injury or “toxic tort” claims.

We are also subject to increasingly stringent laws and regulations that impose strict requirements for the proper management, treatment, storage and disposal of hazardous substances and wastes, restrict air and water emissions from our manufacturing operations, including government-owned facilities we manage, and require maintenance of a safe workplace. These laws and regulations can impose substantial fines and criminal sanctions for violations, and require the installation of costly pollution control equipment or operational changes to limit pollution emissions and/or decrease the likelihood of accidental hazardous substance releases. In addition, if we were convicted of a violation of the Federal Clean Air Act or the Clean Water Act, the facility involved in the violation cannot be used in performing any U.S. government contract awarded during the violation period. We incur, and expect to continue to incur, substantial capital and

operating costs to comply with these laws and regulations. In addition, new laws and regulations, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or the imposition of new clean-up requirements could require us to incur costs in the future that would have a negative effect on our financial condition or results of operations.

We face certain significant risk exposures and potential liabilities that may not be adequately covered by indemnity or insurance.

A significant portion of our business relates to designing, developing and manufacturing advanced defense and technology systems and products. New technologies may be untested or unproven. In addition, we may incur significant liabilities that are unique to our products and services, including missile systems, command and control systems, and air traffic management systems. In some, but not all, circumstances, we may receive indemnification from the U.S. government. While we maintain insurance for certain risks, the amount of our insurance coverage may not be adequate to cover all claims or liabilities, and it is not possible to obtain insurance to protect against all operational risks and liabilities. Accordingly, we may be forced to bear substantial costs resulting from risks and uncertainties of our business which would negatively impact our results of operations and financial condition.

The unpredictability of our results may harm the trading price of our securities, or contribute to volatility.

Our operating results may vary significantly over time for a variety of reasons, many of which are outside of our control, and any of which may harm our business. The value of our securities may fluctuate as a result of considerations that are difficult to forecast, such as:

A rating downgrade by credit agencies could limit our access to capital and cause our borrowing costs to increase.

A downgrade in our credit rating could negatively affect our ability to access capital. If the rating agencies downgrade our ratings, particularly below investment grade, it may significantly limit our access to capital and our borrowing costs would increase. In addition, we would likely be required to pay a higher interest rate in future financings and our potential pool of investors and funding sources would likely decrease.

The Company and its subsidiaries operate in a number of plants, laboratories, warehouses, and office facilities in the United States and abroad. At December 31, 2005, the Company owned, leased, and utilized approximately 42 million square feet of floor space for manufacturing, engineering, research, administration, sales, and warehousing, approximately 92% of which was located in the United States. Of such total, approximately 40% was owned (or held under a long-term ground lease with ownership of the improvements), approximately 54% was leased, and approximately 6% was made available under facilities contracts for use in the performance of U.S. government contracts. At December 31, 2005, the Company had approximately 593,000 square feet of additional floor space that was not in use, including approximately 279,000 square feet in Company-owned facilities.

There are no major encumbrances on any of the Company’s facilities other than financing arrangements which in the aggregate are not material. In the opinion of management, the Company’s properties have been well maintained, are suitable and adequate for the Company to operate at present levels, and the productive capacity and extent of utilization of the facilities are appropriate for the existing real estate requirements of the Company.

At December 31, 2005, the Company’s business segments and other units had major operations at the following locations:

A summary of the owned and leased floor space at December 31, 2005, by business segment or other unit, follows:

In re Raytheon ERISA Litigation. As previously reported, in May 2003 two purported class action lawsuits captioned, Benjamin Wall v. Raytheon Company et al. (Civil Action No. 03-10940-RGS), and Joseph I. Duggan, III v. Raytheon Company et al. (Civil Action No. 03-10995-RGS), were filed in the U.S. District Court in Massachusetts on behalf of participants in the Company’s savings and investment plans who invested in the Company’s stock between August 19, 1999 and May 27, 2003. The two class action complaints are brought pursuant to the Employee Retirement Income Security Act (“ERISA”). Both complaints allege that the Company and certain officers and directors breached ERISA fiduciary and co-fiduciary duties arising out of the Company’s savings and investment plans’ investment in Raytheon stock. The Court consolidated these actions in September 2003. In April 2004, a second consolidated amended complaint (the “Second Consolidated Amended ERISA Complaint”) was filed on behalf of participants and beneficiaries in the Company’s savings and investment plans who invested in Raytheon stock since October 7, 1998. In October 2004, the defendants filed a motion to dismiss the Second Consolidated Amended ERISA Complaint. In September 2005, the Court heard the motion to dismiss but declined to decide the motion subject to a trial on a statute of limitations issue, which is scheduled for June 2006.

Although the Company believes that it has meritorious defenses to the claims made in the above action and intends to contest the matter vigorously, an adverse resolution of the matter could have a material adverse effect on the Company’s financial position and results of operations. The Company is not presently able to reasonably estimate potential losses, if any, related to the matter.

In re Raytheon Securities Litigation. As previously reported, in late 1999, the Company and two of its officers were named as defendants in several class action lawsuits. These lawsuits were consolidated into a single complaint in June 2000, when four additional former or present officers were named as defendants in a Consolidated and Amended Class Action Complaint (the “Consolidated Complaint”) with the caption, In re: Raytheon Securities Litigation (Civil Action No. 12142-PBS), filed in the U.S. District Court in Massachusetts. The Consolidated Complaint principally alleged that the defendants violated federal securities laws by purportedly making misleading statements and by failing to disclose material information concerning the Company’s financial performance during the class period. In May 2004, without admitting any liability or wrongdoing, the Company reached an agreement to settle this class action lawsuit on behalf of the Company and all individual defendants. The terms of the settlement included a cash payment of $210 million and the issuance of warrants for the Company’s stock with a stipulated value of $200 million. The warrants will have a five-year

term with a strike price of $37.50 and will be issued when the settlement proceeds are distributed to the claimants. On December 10, 2004, the Court entered a final judgment resolving all claims asserted against the Company and the individual defendants. The Company expects that the distribution of the settlement proceeds, including the issuance of the warrants, will occur in the second quarter of 2006.

SEC Investigation. As previously reported, the Company continues to cooperate with the staff of the Securities and Exchange Commission (the “SEC”) in a formal investigation into the Company’s disclosure and accounting practices, primarily related to the commuter aircraft business and the timing of revenue recognition at Raytheon Aircraft Company. On April 15, 2005, the Company announced that it had submitted an offer of settlement to the staff of the SEC. The Company, without admitting or denying any wrongdoing, offered to pay a civil penalty of $12 million and consent to the entry of a cease and desist order with respect to violations of Sections 17(a)(2)-(3) of the Securities Act of 1933 and Sections 13(a) and 13(b)(2)(A)-(B) of the Securities Exchange Act of 1934, and related SEC rules. The SEC staff has agreed to recommend that the SEC approve the offer of settlement. The proposed settlement is subject to approval by the SEC.

In addition, the SEC’s investigation of two of the Company’s employees in connection with this matter, one of whom served as the Company’s Chief Financial Officer from December 2002 until April 15, 2005 remains unresolved. Both individuals remain on administrative leave.

The Company is primarily engaged in providing products and services under contracts with the U.S. government and, to a lesser degree, under direct foreign sales contracts, some of which are funded by the U.S. government. These contracts are subject to extensive legal and regulatory requirements and, from time to time, agencies of the U.S. government investigate whether the Company’s operations are being conducted in accordance with these requirements. U.S. government investigations of the Company, whether relating to these contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayments, fines or penalties being imposed upon the Company, the suspension of government export licenses, or the suspension or debarment from future U.S. government contracting. U.S. government investigations often take years to complete and many result in no adverse action against the Company. Defense contractors are also subject to many levels of audit and investigation. Agencies which oversee contract performance include the Defense Contract Audit Agency, the Department of Defense Inspector General, the Government Accountability Office, the Department of Justice, and Congressional Committees. The Department of Justice from time to time has convened grand juries to investigate possible irregularities by the Company.

The Company is involved in various stages of investigation and cleanup relative to remediation of various environmental sites. All appropriate costs expected to be incurred in connection therewith have been accrued. Due to the complexity of environmental laws and regulations, the varying costs and effectiveness of alternative cleanup methods and technologies, the uncertainty of insurance coverage and the unresolved extent of the Company’s responsibility, it is difficult to determine the ultimate outcome of these matters. However, in the opinion of management, any liability is not expected to have a material effect on the Company’s financial position, liquidity or results of operations. Additional information regarding the effect of compliance with environmental protection requirements and the resolution of environmental claims against the Company and its operations is contained in “Environmental Regulation” within Item 1, Item 1A “Risk Factors,” “Commitments and Contingencies” within Item 7, and “Note L—Commitments and Contingencies” within Item 8 of this Form 10-K.

Accidents involving personal injuries and property damage occur in general aviation travel. Raytheon Aircraft Company (RAC) is a defendant in a number of product liability lawsuits that allege personal injury and property damage and seek substantial recoveries including, in some cases, punitive and exemplary damages. RAC maintains partial insurance coverage against such claims and maintains a level of uninsured risk determined by management to be prudent. Additional information regarding aircraft product liability insurance is contained in “Note L—Commitments and Contingencies” within Item 8 of this Form 10-K.

Various other claims and legal proceedings generally incidental to the normal course of business are pending or threatened on behalf of or against the Company. While the Company cannot predict the outcome of these matters, in the opinion of management, any liability arising from them will not have a material adverse effect on the Company’s financial position, liquidity or results of operations after giving effect to provisions already recorded.

No matters were submitted to a vote of the Company’s security holders during the fourth quarter of 2005.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

At February 19, 2006, there were 46,593 record holders of the Company’s common stock. The Company’s common stock is traded on the New York Stock Exchange, the Chicago Stock Exchange and the Pacific Exchange under the symbol “RTN”. The Company’s annual CEO certification to the New York Stock Exchange was issued on June 3, 2005. For information concerning stock prices and dividends paid during the past two years, see “Note P—Quarterly Operating Results (unaudited)” within Item 8 of this Form 10-K.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Raytheon Company and its subsidiaries (Raytheon or the “Company”) is one of the largest defense electronics contractors in the world, serving all branches of the U.S. military and other U.S. government agencies, NATO, and many allied governments. The Company is a leader in its core defense markets: radars and radio-frequency systems; infrared and electro-optical sensors and systems; missiles and precision weapons; and command, control, communications, computer and intelligence systems. In all of these markets, the Company provides full life-cycle services to its customers, including product design, delivery, and mission support.

Raytheon Aircraft Company (RAC or Raytheon Aircraft) is a leading provider of business and special mission aircraft and delivers a broad line of jet, turboprop, and piston-powered airplanes to individual, corporate, and government customers worldwide.

The Company operates in seven principal business segments: Integrated Defense Systems (IDS); Intelligence and Information Systems (IIS); Missile Systems (MS); Network Centric Systems (NCS); Space and Airborne Systems (SAS); Technical Services (RTSC); and Aircraft. For a more detailed description of the segments, see “Business Segments” within Item 1 of this Form 10-K.

The global War on Terrorism, Operation Enduring Freedom and Operation Iraqi Freedom have altered the defense and security environment of the United States and have had, and for the foreseeable future are likely to continue to have, a significant impact on the markets for defense and advanced technology systems and products. The U.S. Department of Defense (the “DoD”) continues to focus on both supporting ongoing operations in Afghanistan and Iraq and transforming the U.S. military to confront future threats. In addition, the Office of Homeland Security and other government agencies continue to focus on enhancing the security of our homeland. To further these priorities, the Company’s defense customers have been focusing on the development of the following defense capabilities: speed, precision, flexibility, and the ability to share knowledge and information. With these capabilities, forces should be better able to seize and sustain initiative, concentrate combat power, and prevent an enemy response. The development and integration of advanced technologies and defense electronics is critical to this new approach.

Overall U.S. defense spending has increased in recent years in connection with the foregoing changes, and the congressionally mandated Quadrennial Defense Review (QDR) released by the DoD in February 2006 indicates continued support of the changes. The QDR recommends certain changes to force structure, particularly with respect to special operations forces, relating to the global War on Terrorism and the insurgency in Iraq. However, at the same time, the QDR also largely maintains the DoD’s transformation initiatives that the Company has supported over the last several years. Specifically, the QDR sets forth the following transformation priorities for which the Company is a key contributor:

The President’s fiscal year 2007 budget and Future Years Defense Plan (“FYDP”), which projects defense costs for the next five years, are generally consistent with the QDR’s recommendations. Within the DoD budget, the Research, Development, Test and Evaluation budget and the Procurement budget, collectively known as the investment accounts, are a key source of funding for the Company’s programs. These investment accounts show continued growth throughout the FYDP. The Company also receives substantial revenue from the DoD Operations and Maintenance accounts, which are also expected to continue to grow, and from the supplemental funds required to support ongoing operations.

Internationally, the threat of additional terrorist activity, coupled with conventional military threats, has led to a continued strong market. In some cases, these opportunities span what in the U.S. would be termed defense and homeland security. Because of the breadth of the Company’s offerings, its systems integration capability, and its strong legacy in the international market, management believes that the Company is well-positioned for continued success in that market.

As the general U.S. economic conditions have improved over the past few years, the general aviation market has been improving as well. Although still below its peak performance in 2001, the industry’s 2005 performance reflected the second consecutive year of improvement compared to the industry’s depressed levels of activity in 2002 and 2003.

Raytheon Aircraft Company’s market is also influenced in part by the capital goods sector and the demand for general aviation products by businesses both domestically and internationally, the U.S. and other governments, as well as high net worth individuals. Traditionally, the used aircraft market has led the recovery of the new aircraft market by 9-12 months and although worldwide levels of used aircraft available for sale have declined over the last 24 months, a downturn in economic conditions could slow or delay market demand for used and therefore ultimately new aircraft.

The decline in the worldwide fleet of used aircraft available for sale, especially late model aircraft less than 10 years old, has resulted in improved pricing and demand of new aircraft and many manufacturers have increased line or production rates. In order to support a continued recovery of the new aircraft market, however, the current worldwide inventory of used aircraft available for sale must be maintained or in some cases reduced even further.

Due to the lower levels of used inventory and strong order activity during the second half of 2005, the industry consensus is that the demand for new aircraft will continue to improve in 2006. Additionally, the introduction of new or upgraded products is also expected to drive increased market demand for products across the industry.

Mission Support focuses on enabling customer success through total life-cycle support that predicts customer needs, senses potential problems, and proactively responds with the most appropriate solutions. Mission Assurance is the commitment to meld the Company’s technologies into the most reliable integrated mission systems in the world to address urgent defense, security, and aircraft needs.

Raytheon’s four SBAs are Missile Defense, Precision Engagement, Homeland Security and Intelligence, Surveillance and Reconnaissance, which are critical markets for the Company. Mission Systems Integration (“MSI”) is the integration of multiple systems (e.g., sensors, C4I, weapons) to deliver a solution to accomplish a specific mission for a customer. MSI requires a thorough understanding of the mission, the systems being integrated, and the concept of operations.

To establish the Beechcraft and Hawker brands, Raytheon is focusing on upgrading its existing portfolio of general aviation aircraft, improving cost competitiveness and flexibility, and providing true Mission Assurance to its customers.

To be a customer-focused company, Raytheon believes that it must (1) perform, by making and keeping its promises to customers, (2) continually listen, anticipate, respond and follow through with its customers, partners and each other, and (3) develop and provide superior customer solutions.

The Company uses these and other measures to assess the performance of the Company and its business segments as well as for executive compensation purposes.

Given the strength of its technologies, domain knowledge, processes, and other resources, the Company believes that it is well positioned to execute on its strategy and capitalize on the trends in the markets in which it operates and meet its financial objectives and goals.

Raytheon’s ability to execute its strategy is enhanced by its technical capabilities and domain knowledge in four core areas: Radio Frequency (RF); Electro-optics and Infrared (EO/IR); Missiles and other precision-guided munitions; and Command and Control, Communications, Computers and Intelligence (C4I). The Company leverages these technologies across its products and business units.

The Company’s strategy is designed to capitalize on the breadth and depth of the Company’s technologies and domain expertise in order to meet the evolving needs of the Company’s customers. The Company is focusing on the following Strategic Business Areas—critical markets that are aligned with the ongoing military operations, the DoD transformation priorities, and the priorities of the Department of Homeland Security. Raytheon is working to identify opportunities and, through the collaboration of the Company’s business units that offer substantial capabilities in these areas, develop integrated solutions to address these areas.

Missile Defense. The Company is working with the U.S. Missile Defense Agency and other companies to develop an operational Ballistic Missile Defense System, a layered system that will detect, identify, and intercept missiles in all phases of flight—the boost, midcourse, and terminal phases. The fundamental components of integrated missile defense are sensors, interceptors, command and control, and systems integration. The Company is a technology leader in all of these areas. The Company’s broad array of solutions provides the capability to detect and respond to threats at all three phases of the missile defense system. The Company’s programs addressing all three phases include Ballistic Missile Defense System Radar, Space Tracking and Surveillance System, and Cobra Judy Radar. The Company’s programs addressing the boost phase include Kinetic Energy Interceptor; the midcourse phase include Upgraded Early Warning Radars, Exo-Atmospheric Kill Vehicle, Sea-Based X-Band Radar, and Standard Missile-3; the terminal phase include the Patriot Air and Missile Defense System, Terminal High-Altitude Area Defense (THAAD) Battle Management Command, Control and Communication, Standard Missile-6, and THAAD Ground-Based Radar.

Precision Engagement. The Company provides mission solutions across the entire precision engagement chain that are designed to address customers’ increasing need to operate jointly (across services and between allied forces), work in a new net-centric paradigm, minimize collateral damage, and strike time-sensitive targets. The Company’s precision engagement systems include: F-15 and F/A-18 Active Electronically Scanned Array radars, Advanced Medium Range Air-to-Air Missile, Miniature Air Launched Decoy, Situation Awareness Data Link, UK Joint Effects Tactical Targeting System, Non-Line-of-Sight Launch System and Precision Attack Missile, Joint Standoff Weapon, Paveway, Tactical Tomahawk, F/A-18 Radar Warning Receiver, and High Power Microwave.

Intelligence, Surveillance and Reconnaissance. Utilizing its sensing, processing, and dissemination technologies, the Company provides integrated systems solutions for observing, locating, processing, deciding, and disseminating actionable information, thereby enabling network-centric operations for decision makers. These abilities are crucial for war fighters to achieve information dominance throughout the entire battlespace. The Company’s key ISR programs include: Global Hawk sensor suite, Distributed Common Ground System, National Polar-orbiting Operational Environmental Satellite Systems, Future Combat Systems Ground Sensor Integrator, and numerous classified programs.

Homeland Security. The Company continues to leverage the technologies and solutions it has developed for its traditional defense markets to provide solutions to homeland security customers. Recent efforts have focused on the exploitation of the Company’s expertise in the collection and analysis of large amounts of data. The Company has been awarded programs in border security, most notably US-VISIT, and in related areas.

Raytheon continues to grow and expand its Mission Systems Integration (MSI) initiative. The Company believes that its customers are increasingly seeking a Mission Systems Integrator for their programs and the Company is well positioned to expand its MSI work over the next several years. Examples of the Company’s MSI success in 2005 include:

Raytheon’s customer focus is a critical part of its strategy—underpinned by a focus on performance, relationships, and solutions.

Performance means being able to meet customer commitments, and is ensured through strong processes, metrics, and oversight. Raytheon has a “process architecture” that spans its broad programs and pursuits. It consists of processes such as Integrated Product Development System (IPDS) which assures consistency of evaluation and execution at each gate in a program life-cycle. These processes are linked to an array of front-end and back-end metrics. With this structure, Raytheon is able to track results and be alerted to potential issues through numerous oversight mechanisms, including operating reviews, annual operating plan reviews, and human resource reviews.

Raytheon is continuing to build strong customer relationships by listening to customers, working with them as partners, and including them on Raytheon Six Sigma teams to jointly improve their programs and processes. Raytheon is increasingly focused on the importance of speed and agility in responding to its customers’ changing requirements. Recent examples of Raytheon teaming with its customers and delivering rapid, effective responses to real problems include: PSDS2, a surveillance system delivered to the U.S. Army in 6 months; RAID, elevated sensors first deployed to Afghanistan in 36 days; and MTS, an EO/IR system that became operational for combat use with Hellfire missiles in 4 months.

The Company currently is involved in approximately 8,000 active programs and has 13,000 contracts. No individual contract exceeded 4% of Company sales in 2005. Management believes that the Company’s diverse portfolio of programs and capabilities is well suited to a changing defense environment. Raytheon, however, faces numerous challenges and risks.

The Company’s programs generally are implemented by the award of individual contracts and subcontracts and are subject to congressional appropriations. Congress generally appropriates funds on a fiscal year basis even though a program may extend for several years. Consequently, programs are often only partially funded initially, and additional funds are committed only as Congress makes further appropriations. U.S. government contracts and subcontracts under a program are subject to termination or adjustment if appropriations for such program are not available or change. U.S. government contracts are also subject to oversight audits and contain provisions for termination. Failure to comply with U.S. government regulations could lead to suspension or debarment from U.S. government contracting.

Sales to the U.S. government may be affected by changes in procurement policies, budget considerations, changing defense requirements, and political developments. The influence of these factors, which are largely beyond the Company’s control, could impact the Company’s financial position or results of operations.

In addition, the Company’s programs typically involve the development, application, and manufacturing of advanced defense and technology systems and products aimed at achieving challenging goals. New technologies may be untested or unproven. In some instances, product requirements or specifications may be modified. As a result, the Company may experience technological and other performance difficulties, which may result in delays, setbacks, cost overruns, and product failures in connection with its programs.

As a U.S. government contractor, the Company is subject to specific import and export, procurement and other regulations and requirements. Failure to comply with these regulations and requirements could result in reductions of the value of contracts, contract modifications or termination, and the assessment of penalties and fines and lead to suspension or debarment, for cause, from government contracting or subcontracting for a period of time. Among the causes for debarment are violations of various statutes, including those related to procurement integrity, export control, government security regulations, employment practices, the protection of the environment, the accuracy of records, and the recording of costs. Under many government contracts, the Company is required to maintain facility and personnel security clearances complying with DoD requirements.

The Company is also subject to routine audits and investigations by U.S. government agencies such as the Defense Contract Audit Agency (DCAA). These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations, and standards. The DCAA also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation, and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. If an audit uncovers improper or illegal activities, the Company may be subject to civil and criminal penalties and administrative sanctions, which could include: termination of contracts; forfeiture of profits; suspension of payments; fines; and suspension or prohibition from doing business with the U.S. government.

As discussed in more detail throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations:

Gross bookings were $24.8 billion in 2005, $25.7 billion in 2004, and $22.7 billion in 2003, resulting in backlog of $34.4 billion, $32.5 billion, and $27.5 billion at December 31, 2005, 2004, and 2003, respectively. Backlog represents future sales expected to be recognized over the next several years.

Net sales were $21.9 billion in 2005, $20.2 billion in 2004, and $18.1 billion in 2003. The increase in sales was a result of strong growth at the Company’s government and defense businesses, primarily Integrated Defense Systems and Missile Systems, as well as growth at Raytheon Aircraft.

Operating income was $1.7 billion in 2005, $1.4 billion in 2004, and $1.3 billion in 2003. Operating income as a percent of net sales was 7.7%, 6.9%, and 7.3% in 2005, 2004, and 2003, respectively. Included in operating income was a FAS/CAS Pension Adjustment, described below in Consolidated Results of Operations, of $465 million in 2005, $474 million in 2004, and $109 million of expense in 2003. The FAS/CAS Pension Adjustment in 2006 is expected to be approximately $360 million of expense. Also included in operating income in 2003 were charges on certain programs at Network Centric Systems and Technical Services of $276 million.

Operating cash flow from continuing operations was $2.5 billion in 2005, $2.1 billion in 2004, and $2.6 billion in 2003. Total debt was $4.5 billion at December 31, 2005 versus $5.2 billion at December 31, 2004.

The Company’s consolidated financial statements are based on the application of generally accepted accounting principles which requires the Company to make estimates and assumptions about future events that affect the amounts reported in its financial statements and the accompanying notes. Future events and their effects cannot be determined with certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from those estimates, and any such differences may be material to the Company’s financial statements. The Company believes that the policies set forth below may involve a higher degree of judgment and complexity in their application than the Company’s other accounting policies and represent the critical accounting policies used in the preparation of its financial statements. The Company believes its judgments related to these accounting policies are appropriate. However, if different assumptions or conditions were to prevail, the results could be materially different from the amounts recorded.

Revenue Recognition—Sales under long-term contracts generally are recorded under the percentage of completion method. Incurred costs and estimated gross margins are recorded as sales when work is performed based on the percentage that incurred costs bear to the Company’s estimates of total costs and contract value. Cost estimates include direct and indirect costs such as labor, materials, warranty, and overhead. Some contracts contain incentive provisions based upon performance in relation to established targets, which are included at estimated realizable value. Contract change orders and claims are included when they can be reliably estimated and realization is considered probable. Due to the long-term nature of many of the Company’s programs, developing estimates of total costs and contract value often requires significant judgment. Factors that must be considered in estimating the work to be completed and ultimate contract recovery include labor productivity and availability, the nature and complexity of the work to be performed, the impact of change orders, availability of materials, the impact of delayed performance, availability and timing of funding from the customer, award fee estimations, and the recoverability of claims. In 2005, 2004, and 2003, operating income as a percent of net sales for the government and defense businesses did not vary by more than 2.3%. A 2.3% change in operating income as a percent of net sales for the government and defense businesses in 2005 would change the Company’s operating income by approximately $460 million.

Lot Accounting—The Company uses lot accounting for new commercial aircraft introductions at Raytheon Aircraft. Lot accounting involves selecting an initial lot size at the time a new aircraft begins to be delivered and measuring an average margin over the entire lot for each aircraft sold. The costs attributed to aircraft delivered are based on the estimated average margin of all aircraft in the lot and are determined under the learning curve concept, which anticipates a predictable decrease in unit costs from cost reduction initiatives and as tasks and production techniques become more efficient through repetition. Once the initial lot has been completed, the use of lot accounting is discontinued. The selection of lot size is a critical judgment. The Company determines lot size based on several factors, including the size of firm backlog, market and competitive conditions, the expected annual production for the aircraft, and experience on similar new aircraft. The size of the initial lot for the Beechcraft Premier I is 200 units. The size of the initial lot for the Hawker 4000 is 75 units. A 5% increase in the remaining estimated costs to produce the initial lots of these two aircraft would reduce the Company’s operating income by approximately $64 million in the aggregate.

Valuation of Used Aircraft and Aircraft Materials and Parts—The valuation of used aircraft in inventories, which are stated at cost, but not in excess of realizable value, requires significant judgment. The valuation of used aircraft is also considered in assessing the realizable value of certain commuter aircraft-related assets which serve as collateral for the underlying financing arrangements. As part of the assessment of realizable value, the Company evaluates many factors including current market conditions, future market conditions, the age and condition of the aircraft, and availability levels for the aircraft in the market. A 5% decrease in the aggregate realizable value of used aircraft in inventory at December 31, 2005, would result in an impairment charge of approximately $10 million. The valuation of aircraft materials and parts that support the worldwide fleet of aircraft, which are stated at cost, but not in excess of realizable value, also requires significant judgment. As part of the assessment of realizable value, the Company evaluates many factors including the expected useful life of the aircraft, some of which have remained in service for up to 50 years. A 5%

decrease in the aggregate realizable value of aircraft materials and parts at December 31, 2005, would result in an impairment charge of approximately $5 million. The Company assumed an orderly disposition for both used aircraft and aircraft materials and parts in connection with the assessments of realizable value.

Impairment of Goodwill and Long-lived Assets—The Company evaluates the recoverability of long-lived assets upon indication of possible impairment by measuring the carrying amount of the assets against the related estimated undiscounted cash flows. When an evaluation indicates that the future undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are adjusted to their estimated fair value. The determination of what constitutes an indication of possible impairment, the estimation of future cash flows, and the determination of estimated fair value are all significant judgments. In addition, the Company performs an annual goodwill impairment test in the fourth quarter of each year. The Company estimates the fair value of reporting units using a discounted cash flow model based on the Company’s most recent five-year plan and compares the estimated fair value to the net book value of the reporting unit, including goodwill. Preparation of forecasts for use in the five-year plan involves significant judgments. Changes in these forecasts could affect the estimated fair value of one or more of the Company’s reporting units and could result in a goodwill impairment charge in a future period; however, a 10% decrease in the current fair value of each of the Company’s reporting units would not result in a goodwill impairment charge except at Flight Options. In 2005, the Company recorded a $22 million pretax, $19 million after-tax, goodwill impairment charge at Flight Options, as described in Note A, Accounting Policies of the Notes to the Financial Statements.

Pension Costs—The Company has pension plans covering the majority of its employees, including certain employees in foreign countries. The selection of the assumptions used to determine pension expense or income involves significant judgment. The Company’s long-term return on asset (ROA) and discount rate assumptions are considered the key variables in determining pension expense or income. To develop the long-term ROA assumption, the Company considered the current level of expected returns on risk-free investments, the historical level of the risk premium associated with the other asset classes in which the Company has invested pension plan assets, and the expectations for future returns of each asset class. Since the Company’s investment policy is to employ active management strategies in all asset classes, the potential exists to outperform the broader markets; therefore, the expected returns are higher than the broader markets. The expected return for each asset class was then weighted based upon an asset allocation within the Company’s policy allocation ranges to develop the long-term ROA assumption. The policy asset allocation ranges are between 50% and 75% equities with a 9.9% expected return, between 20% and 40% debt securities with a 6.2% expected return, between 2% and 7% real estate with an 8.2% expected return, and between 2% and 17% other (including private equity and cash) with a 7.0% expected return. The long-term ROA assumption for the Company’s domestic pension plans in 2006 is 8.75%, unchanged from 2005. An increase or decrease of 25 basis points in the expected ROA assumption would increase or decrease the Company’s pension expense in 2006 by approximately $30 million. The discount rate assumption was determined by using a model consisting of theoretical bond portfolios that closely match the various durations of the Company’s pension liability duration. The discount rate assumption for the Company’s domestic pension plans in 2006 is 5.75%, unchanged from 2005. The Company’s pension expense is expected to be approximately $810 million in 2006 and $723 million in 2007. For every 2.5% that the actual domestic pension plan asset return exceeds or is less than the long-term ROA assumption for 2006, the Company’s pension expense for 2007 would change by approximately $17 million. An increase or decrease of 25 basis points in the discount rate assumption for 2007 would increase or decrease the Company’s pension expense for 2007 by approximately $45 million.

In addition, the Company has $5.1 billion of pension and $427 million of retiree medical deferred actuarial losses resulting from changes in discount rates, differences between actual and assumed asset returns, medical cost inflation and differences between actual and assumed demographic experience (actual earnings, rates of turnover and retirement). These losses are amortized and included in future pension and retiree medical expense over the average employee service period of approximately 12 years. Although they are included in the liabilities disclosed in Note N, Pension and Other Employee Benefits, of the Notes to the Financial Statements, they have not yet been recognized on the Company’s balance sheet.

Effective December 31, 2005, the Company updated its mortality assumption for its pension and post retirement benefit programs to a blend of the Company’s own historical experience and a table representing broad expectations of U.S. mortality rates to reflect changes in the lifespan of the pension population. This assumption change results in an increase in 2006 pension expense of $130 million.

Net sales were $21.9 billion in 2005, $20.2 billion in 2004, and $18.1 billion in 2003. The increase in sales was due to higher U.S. government expenditures in the Company’s government and defense businesses, as well as higher sales at RAC. Sales to the U.S. Department of Defense were 67% of sales in 2005 and 2004, and 65% in 2003. Total sales to the U.S. government, including foreign military sales, were 74% of sales in 2005, 2004, and 2003. Total international sales, including foreign military sales, were $4.2 billion or 19% of sales in 2005, $3.7 billion or 18% in 2004, and $3.5 billion or 19% in 2003. In general, international sales, excluding foreign military sales, have more favorable cash and profit terms than domestic sales.

Gross margin (net sales less cost of sales) was $3.7 billion in 2005, $3.3 billion in 2004, and $3.1 billion in 2003, or 16.7% of sales in 2005, 16.1% in 2004, and 16.9% in 2003. Included in gross margin was a FAS/CAS Pension Adjustment, described below, of $465 million, $474 million, and $109 million of expense in 2005, 2004, and 2003, respectively. The increase in the FAS/CAS Pension Adjustment in 2004 was due primarily to the reduction in the Company’s discount rate assumption under Statement of Financial Accounting Standards No. 87, Employers’ Accounting for Pensions (SFAS No. 87), and the actual rate of return on pension plan assets in 2000 and 2001. The decrease in gross margin as a percent of sales for 2004 was due to the increase in the FAS/CAS Pension Adjustment. Included in gross margin for 2003 were charges of $237 million at Network Centric Systems and $39 million at Technical Services.

The FAS/CAS Pension Adjustment represents the difference between the Company’s pension expense or income under SFAS No. 87 and the Company’s pension expense under Cost Accounting Standards (CAS) and is reported as a separate line item in the Company’s segment results. SFAS No. 87 outlines the methodology used to determine pension expense or income for financial reporting purposes, which is not necessarily indicative of the funding requirements of pension plans, which are determined by other factors. Cost Accounting Standards (CAS) proscribe the allocation to and recovery of pension costs on U.S. government contracts and is a major factor in determining pension funding requirements. The results for each segment only include pension expense as determined under CAS, which can generally be recovered through the pricing of products and services to the U.S. government.

Administrative and selling expenses were $1,474 million or 6.7% of sales in 2005, $1,385 million or 6.8% of sales in 2004, and $1,261 million or 7.0% of sales in 2003. Included in administrative and selling expenses in 2005 was a $22 million goodwill impairment charge related to Flight Options described below in Segment Results.

Research and development expenses were $503 million or 2.3% of sales in 2005, $491 million or 2.4% of sales in 2004, and $487 million or 2.7% of sales in 2003.

Operating income was $1,687 million or 7.7% of sales in 2005, $1,388 million or 6.9% of sales in 2004, and $1,316 million or 7.3% of sales in 2003. The changes in operating income by segment are described below in Segment Results.

Interest expense was $312 million in 2005, $418 million in 2004, and $537 million in 2003. The decreases in interest expense in 2005 and 2004 were due to lower average debt for those years.

Other (income) expense, net was $13 million of income in 2005, $436 million of expense in 2004, and $67 million of expense in 2003. Included in other income, net in 2005 was a $45 million gain on the sale of the Company’s investment in Indra ATM S.L., a Spanish joint venture, partially offset by a $12 million charge related to the Company’s proposed settlement with the Securities and Exchange Commission (SEC) as described in Note L, Commitments and Contingencies of the Notes to the Financial Statements and a $10 million charge related to the early redemption of debt. Included in other expense, net in 2004 was a $325 million charge related to the Company’s settlement of a securities class action lawsuit described in Note L, Commitments and Contingencies of the Notes to the Financial Statements and a $132 million charge related to the Company’s repurchase of long-term debt and subordinated notes payable.

The effective tax rate was 34.6% in 2005, 24.2% in 2004, and 29.8% in 2003, reflecting the U.S. statutory rate of 35% reduced by ESOP dividend deductions, export-related tax benefits, and research tax credits. Included in the effective tax rate in 2005 was the impact of the nondeductible $12 million proposed settlement with the SEC, the impact of the nondeductible portion of the $22 million Flight Options goodwill impairment charge, an $18 million accrual related to adjustments resulting from examinations by taxing authorities and other tax issues, and a $5 million accrual related to the repatriation of earnings from foreign subsidiaries. Included in the effective tax rate in 2004 was a $42 million benefit from

the change in tax law primarily related to the extension of the foreign tax credit carryforward periods from five to 10 years. At December 31, 2005, the Company estimates that it has utilized all of its net operating loss carryforwards.

Income from continuing operations was $942 million or $2.08 per diluted share on 453.3 million average shares outstanding in 2005, $439 million or $0.99 per diluted share on 442.2 million average shares outstanding in 2004, and $535 million or $1.29 per diluted share on 415.4 million average shares outstanding in 2003. The increase in average shares outstanding in 2004 was due to common stock issued in connection with the Company’s equity security units described below in Capital Structure and Resources. The increase in average shares outstanding in 2005 was due to the common stock issued in 2004 being outstanding for the full year.

The loss from discontinued operations, net of tax, described below in Discontinued Operations, was $71 million or $0.16 per diluted share in 2005, $63 million or $0.14 per diluted share in 2004, and $170 million or $0.41 per diluted share in 2003.

Effective January 1, 2004, the Company changed the measurement date for its pension and other postretirement benefit plans from October 31 to December 31. This change in measurement date was accounted for as a change in accounting principle. The cumulative effect of this change in accounting principle was a gain of $53 million pretax for pension benefits and a gain of $10 million pretax for other postretirement benefits. Using the Company’s year-end as the measurement date for pension and other postretirement benefit plans more appropriately reflects the plans’ financial status for the years then ended. In 2004, the total cumulative effect of the change in accounting principle was a gain of $63 million pretax, $41 million after-tax, or $0.09 per diluted share.

Net income was $871 million or $1.92 per diluted share in 2005, $417 million or $0.94 per diluted share in 2004, and $365 million or $0.88 per diluted share in 2003.

Reportable segments have been determined based upon product lines and include the following: Integrated Defense Systems, Intelligence and Information Systems, Missile Systems, Network Centric Systems, Space and Airborne Systems, Technical Services, Aircraft, and Other. In 2005, certain programs within Intelligence and Information Systems, Network Centric Systems and Technical Services were realigned within those same segments. Information for all prior periods presented was reclassified to reflect these changes.

The net sales of the Company’s government and defense businesses increased in 2004 and 2005. These increases were generally due to growth in U.S. defense spending. The Company currently expects these market trends to continue to positively impact the Company’s sales in 2006. The Company’s expectations are based on the Company’s planning assumptions and projections and assessment of numerous factors, including macro-environmental factors which are outside the Company’s control. The Company believes the current market environment is generally consistent with the Company’s planning assumptions and performance for the defense businesses, however, there are numerous factors which could materially impact the environment, including rising budget deficits, costs associated with current U.S. Department of Defense operations overseas, and other issues affecting the U.S. Department of Defense budget and may represent a risk to the Company’s expected future performance.

The Company expects that the Space and Airborne Systems operating margin for 2006 will be less than its margin in 2005 primarily due to the favorable margin impact of certain contracts nearing completion in 2005.

The net sales for Aircraft increased in 2004 and 2005. The Company expects an increase in sales at Aircraft in 2006 but not at the same growth rate as that experienced in 2005 due to higher volume from derivative aircraft introductions in 2005 and market demand for Beechcraft and Hawker products in 2006 that is increasing at a rate lower than 2005.

Integrated Defense Systems (IDS)—IDS provides integrated air defense, maritime, and joint battlespace solutions. IDS had 2005 sales of $3.8 billion versus $3.5 billion in 2004 and $2.9 billion in 2003. The increase in sales in 2005 was due to growth on international programs and the Cobra Judy Replacement Mission Equipment program. The increase in sales in 2004 was due to continued growth on DD(X), the Navy’s future destroyer program. Operating income was $548 million in 2005, versus $417 million in 2004 and $331 million in 2003. The increase in operating margin in 2005 was due to higher sales on international programs.

Intelligence and Information Systems (IIS)—IIS provides systems, subsystems, and software engineering services for national and tactical intelligence systems, as well as for homeland security and information technology solutions. IIS had 2005 sales of $2.5 billion versus $2.3 billion in 2004 and $2.2 billion in 2003. The increase in sales in 2005 was due to growth in classified programs. The increase in sales in 2004 was due to growth in the Distributed Common Ground System (DCGS) program and growth in classified programs. Operating income was $229 million in 2005, versus $203 million in 2004 and $198 million in 2003.

Missile Systems (MS)—MS provides air-to-air, precision strike, surface Navy air defense, and land combat missiles, guided projectiles, kinetic kill vehicles, and directed energy weapons. MS had 2005 sales of $4.1 billion versus $3.8 billion in 2004 and $3.5 billion in 2003. The increase in sales in 2005 was due primarily to the ramp up on Tactical Tomahawk and several developmental programs. The increase in sales in 2004 was due to continued growth in missile defense, including work on the Standard Missile-3 program. Operating income was $431 million in 2005 versus $436 million in 2004 and $424 million in 2003. The decline in operating margin in 2005 and 2004 was due to the wind-down of cost recovery for prior year restructuring actions. The costs related to these restructuring actions were accrued in 1997 through 2000, but were being recovered through the pricing of products and services to the U.S. government over a five-year period. The wind-down of this recovery was substantially completed in 2004.

Network Centric Systems (NCS)—NCS develops and produces net-centric mission solutions for network sensors, command and control communications, air traffic management, and homeland security. NCS had 2005 sales of $3.2 billion versus $3.1 billion in 2004 and $2.7 billion in 2003. The increase in sales in 2005 was due to growth in developmental and communications programs. Operating income was $333 million in 2005 versus $269 million in 2004 and $13 million in 2003. The increase in operating margin in 2005 was due to improved performance and program mix. Included in 2003 were charges resulting in a reduction in sales and operating income of $228 million and $237 million, respectively, related to performance issues on certain NCS programs.

Space and Airborne Systems (SAS)—SAS designs and develops integrated systems and solutions for advanced missions including unmanned aerial operations, electronic warfare, active electronically scanned array radars, airborne processors, weapon grade lasers, missile defense, and intelligence, surveillance, and reconnaissance systems. SAS had 2005 sales of $4.2 billion, versus $4.1 billion in 2004 and $3.7 billion in 2003. Operating income was $606 million in 2005 versus $568 million in 2004 and $492 million in 2003. The increase in operating margin in 2005 was due to prior year charges on an international program of $55 million as a result of a qualification test failure, and productivity improvements on mature production programs, partially offset by cost growth on development programs. Operating margin was higher in 2004 due primarily to productivity improvements on production programs, partially offset by prior year charges.

Technical Services (RTSC)—RTSC provides technology solutions for defense, federal government and commercial customers worldwide, specializing in counter-proliferation and counter-terrorism, base and range operations, customized engineering and manufacturing services, and mission support. RTSC had 2005 sales of $2.0 billion versus $2.0 billion in 2004 and $1.9 billion in 2003. Operating income was $146 million in 2005, versus $148 million in 2004 and $109 million in 2003. Included in 2003 operating income were charges of $39 million related to an unfavorable change in the scope on a long-term contract of $22 million and a provision for the collectibility of certain unbilled costs of $17 million.

Raytheon Aircraft Company (RAC)—RAC designs, develops, manufactures, markets, and provides global support for business jets, turboprops, and piston-powered aircraft for the world’s commercial, fractional ownership, and military aircraft markets. RAC had 2005 sales of $2.9 billion versus $2.4 billion in 2004 and $2.1 billion in 2003. The increase in sales in 2005 was due to higher new commercial and special mission aircraft sales. The increase in sales in 2004 was primarily due to higher new aircraft sales. Operating income was $142 million in 2005, versus $63 million in 2004 and $2 million in 2003. The increase in operating income in 2005 was due to commercial and special mission volume and sales mix, and continued improved operating performance. The increase in operating income in 2004 was due to higher volume on new aircraft sales as well as productivity and cost savings initiatives implemented throughout 2003 and 2004. Included in 2005 and 2004 operating income was a $31 million and a $34 million, respectively, favorable profit adjustments on the military training aircraft programs. Included in 2003 operating income was a $50 million favorable

profit adjustment on the military training aircraft programs partially offset by a $22 million charge on the Premier program reflecting cost estimate increases. The favorable profit adjustments on the military training aircraft programs were due to option exercises and productivity improvements. Since the last contract option related to the military training aircraft programs was exercised in 2005, no favorable profit adjustment is expected in 2006. The Company expects to be awarded a new multiyear military training aircraft production contract in 2006.

The Company has made significant investments in its Premier and Hawker 4000 aircrafts, the realization of which is contingent upon future sales at forecasted prices and reductions in production costs on future deliveries. The Company uses lot accounting for new commercial aircraft introductions. The size of the initial lot for the Premier I and the Hawker 4000 is 200 and 75 units, respectively, and the Company expects to complete the lots in 2007 and 2009, respectively. During the fourth quarter of 2004, the Federal Aviation Administration granted a provisional type certification for the Hawker 4000 aircraft. Final certification has not been received and no revenue has been recognized on this aircraft.

Other—The Other segment, which is comprised of Flight Options LLC (FO), Raytheon Airline Aviation Services LLC (RAAS), and Raytheon Professional Services LLC (RPS) had 2005 sales of $781 million versus $675 million in 2004 and $573 million in 2003. FO offers services in the aircraft fractional ownership industry. RAAS manages the long-term wind-down of the Company’s commuter aircraft business. RPS works with customers to design and execute learning solutions. The increase in sales in 2004 was primarily due to the consolidation of FO in June 2003. The Other segment had an operating loss of $117 million in 2005 versus $40 million in 2004 and $34 million in 2003. The increase in operating loss in 2005 was primarily due to the operating results of FO described below, and to a lesser extent RAAS. The higher losses at RAAS were due to higher aircraft maintenance expense in the period.

The Other segment’s results in 2005 were principally comprised of the operations of FO. Although FO has had a history of operating losses, the higher losses in 2005 are due to increased supplemental lift (higher third party chartering expense) and maintenance expense related to the operational impacts primarily from older aircraft in the fleet, and the timing of peak customer demand. The older aircraft in the fleet are being retired and replaced by newer aircraft which is expected to be substantially complete by 2008. At the same time, FO is also taking action to reduce the number of different types of aircraft in its fleet from twelve to four and in connection with this action reduce current operating costs. Although the Company believes that these actions will result in improved financial results, there can be no assurance that these actions will have the expected effect. In addition, in 2005, the Company recorded a $22 million pretax, $19 million after-tax goodwill impairment charge related to FO. The impairment was a result of changes in valuation assumptions, the effect of projecting recent performance variances on future periods, and the increase in goodwill as a result of the transaction described below. The Company also recorded a $7 million charge in 2005 related to a third party settlement of a lawsuit against FO and its minority shareholders.

In December 2005, the Company settled all disputes with the FO minority shareholders and acquired the minority shares for $28 million in cash and assumed liabilities and now owns 100% of FO. The Company’s net investment in FO was approximately $223 million at December 31, 2005. If losses at FO were to continue over the longer-term or if FO’s financial objectives were no longer expected to be achieved, the Company’s investment in FO could become further impaired and additional charges may be required. FO must demonstrate substantial operating results improvement to achieve its financial objectives including achieving its sales forecasts, reducing maintenance expense, and improving dispatch availability over the 2005 average.

RAAS has exposure to outstanding financing arrangements for commuter aircraft, with the aircraft serving as collateral for these arrangements. Commuter aircraft customers of RAAS are generally thinly capitalized companies whose financial condition could be significantly affected by sustained higher fuel costs, industry consolidation, and declining commercial aviation market conditions. At December 31, 2005 and December 31, 2004, the Company’s exposure on commuter aircraft assets was approximately $509 million relating to 253 aircraft and approximately $614 million relating to 297 aircraft, respectively. The carrying value of commuter aircraft assets assumes an orderly disposition of these assets. If the Company were to dispose of these assets in an other than orderly disposition, or sell the business in its entirety, the value realized would likely be reduced.

Funded backlog excludes U.S. and foreign government contracts for which funding has not been appropriated.

The gross bookings in each year are influenced by timing of awards that may cover multiple fiscal years. For example, in 2005, Integrated Defense Systems booked $1.7 billion to continue the ship system integration and detail design for the U.S. Navy’s DD(X) Destroyer and $631 million to provide Taiwan with an Early Warning Surveillance Radar System. In 2005, SAS booked $586 million for the production of 190 APG-79 Active Electronically Scanned Array (AESA) radars for the F/A-18 Super Hornet program. In 2004, SAS booked over $1.3 billion on a number of classified contracts. In 2004, Missile Systems booked $2.1 billion for the Kinetic Energy Interceptor system contract.

In 2005, Raytheon Aircraft received an order for approximately $1 billion for 50 new Hawker 4000 super-midsize business jets to be delivered through 2015 and a guaranteed maintenance program which runs for ten years from the delivery of each aircraft.

In 2000, the Company sold its Raytheon Engineers & Constructors businesses (RE&C) to Washington Group International, Inc. (WGI). As a result of WGI’s bankruptcy, the Company was required to perform various contract and lease obligations under letters of credit, surety bonds, and guarantees (Support Agreements) that it had provided to project owners and other parties.

The Company has settled many of its Support Agreement obligations. For its remaining Support Agreement obligations, the Company has various risks and exposures, including warranty close out, various liquidated damages issues, and potential adverse claims resolution.

The Company is currently engaged in a dispute with AES Red Oak LLS (AES) over the close out of the Red Oak Power project. The dispute involves, among other things, a draw down of $30 million by AES in August 2004 from a line of credit provided by the Company.

In 2005, 2004, and 2003, the pretax loss from discontinued operations related to RE&C was $41 million, $42 million, and $231 million, respectively. In 2005 and 2004, the Company recorded after-tax charges of $23 million and $24 million, respectively, for an estimated liability for foreign tax-related matters. Although not expected to be material, additional losses on foreign tax-related matters could be recorded in the future as estimates are revised or the underlying matters are settled. Included in 2003 were charges of $176 million related to the completion of the Mystic Station and Fore River construction projects in Massachusetts.

The after-tax loss from discontinued operations related to RE&C was $50 million, $48 million, and $151 million in 2005, 2004 and 2003, respectively.

Net cash used in operating activities from discontinued operations related to RE&C was $25 million in 2005 versus $61 million in 2004 and $513 million in 2003.

In 2002, the Company sold its Aircraft Integration Systems business (AIS) for $1,123 million, net, subject to purchase price adjustments. As part of the transaction, the Company retained the responsibility for performance of the Boeing Business Jet (BBJ) program and retained certain assets related to the BBJ program, which is now essentially complete. In January 2006, a dispute regarding the AIS purchase price was resolved in arbitration and the Company recorded a pretax charge of $26 million in 2005 related to this settlement.

In 2005, 2004, and 2003, the pretax loss from discontinued operations related to AIS was $33 million, $23 million, and $30 million, respectively, primarily related to the completion of the BBJ program and the resolution of the purchase price dispute.

In 2005, the total loss from discontinued operations was $74 million pretax, $71 million after-tax, or $0.16 per diluted share versus $65 million pretax, $63 million after-tax or $0.14 per diluted share in 2004 and $261 million pretax, $170 million after-tax, or $0.41 per diluted share in 2003.

The Company is currently employing a capital deployment plan, announced in December 2004, that balances funding for growing the Company’s business, debt reductions, pension contributions, dividend payments, and stock repurchases. The Company is also focused on increasing Return On Invested Capital (ROIC) as well as continued strong cash generation in 2006.

Operating Activities—Net cash provided by operating activities in 2005 was $2,515 million versus $2,071 million in 2004 and $2,034 million in 2003. Net cash provided by operating activities from continuing operations was $2,546 million in 2005, $2,114 million in 2004 and $2,567 million in 2003. Included in 2004 was a $210 million payment made in connection with the settlement of the securities class action lawsuit as discussed in Note L, Commitments and Contingencies of the Notes to the Financial Statements. The Company received approximately $75 million of insurance proceeds related to this lawsuit in 2005. Total net cash tax payments were approximately $56 million, $5 million and $13 million in 2005, 2004, and 2003, respectively. Tax payments in 2006 are expected to approximate $360 million.

Total contributions (required and discretionary) to the Company’s pension plans are expected to be approximately $640 million in 2006. Congress is currently considering pension funding reform legislation which would increase funding requirements for most companies sponsoring defined benefit pension plans. If enacted, the pension funding reform legislation could result in an increase in the Company’s pension contribution requirement beginning in 2006.

Savings and investment plan activity includes certain items related to the Company’s 401(k) plan that were funded through the issuance of the Company’s common stock and are non-cash operating activities included on the 2004 and 2003 statement of cash flows. In 2004, the Company began funding its 401(k) plan match with cash.

Although not expected to be material, due to potential noncompliance by certain suppliers with DoD procurement requirements, the Company has experienced delays in deliveries and collections and has not billed customers for certain portions of products as the Company and other industry participants work to resolve this matter with the DoD.

The Company provides long-term financing to its aircraft customers. Origination of financing receivables was $315 million in 2005, $325 million in 2004, and $402 million in 2003. Collection of financing receivables not sold was $411 million in 2005, $459 million in 2004, and $588 million in 2003. The Company received proceeds of $23 million in 2005, $59 million in 2004 and $279 million in 2003 related to the sale of certain general aviation finance receivables, described below in Off-Balance Sheet Arrangements.

Investing Activities—Net cash used in investing activities was $436 million in 2005 versus $532 million in 2004 and $708 million in 2003. Capital expenditures were $338 million in 2005, $363 million in 2004, and $428 million in 2003. Capital expenditures in 2006 are expected to approximate $400 million. Capitalized expenditures for internal use software were $75 million in 2005, $103 million in 2004, and $98 million in 2003. Capitalized expenditures for internal use software in 2006 are expected to approximate $100 million. In 2003, the Company bought back the assets remaining in a synthetic lease facility for $125 million.

Proceeds from the sale of operating units and investments were $78 million in 2005 versus $47 million in 2004 and $111 million in 2003. In 2005, the Company sold its investment in Indra ATM S.L., a Spanish joint venture, for $59 million. In 2004, the Company sold its commercial infrared business for $43 million. In 2003, the Company sold the remaining interest in its former aviation support business for $97 million.

In 2005, the Company paid the third and final installment of $60 million related to its 2003 acquisition of Solipsys Corporation. Also in 2005, the Company paid $39 million for the acquisition of UTD, Inc. and $26 million to acquire the remaining interest in Flight Options. In 2003 and 2004, the Company paid $40 million and $70 million, respectively related to the acquisition of Solipsys Corporation. Also in 2004, the Company paid $42 million for the acquisition of Photon Research Associates, Inc.

In 2003, the Company paid $130 million related to the Space Imaging credit facility guarantee, described below in Major Affiliated Entities.

Financing Activities—Net cash used in financing activities was $1,433 million in 2005 versus $1,644 million in 2004 and $1,209 million in 2003. Dividends paid to stockholders were $387 million in 2005, $349 million in 2004, and $331 million in 2003. The quarterly dividend rate was $0.22 per share for each of the four quarters of 2005 versus $0.20 per share for each of the four quarters of 2004 and 2003. Although the Company does not have a formal dividend policy, management believes that a reasonable dividend payout ratio based on the current industry environment and market conditions is approximately one third of the Company’s economic earnings (income excluding FAS/CAS Pension Adjustment). Dividends are subject to approval by the Board of Directors.

In 2004, the Board of Directors authorized the repurchase, between January 1, 2005 and December 31, 2006, of up to $700 million of the Company’s outstanding common stock. In 2005, the Company repurchased $436 million of common stock under this program.

Total debt was $4.5 billion at December 31, 2005 and $5.2 billion at December 31, 2004. Cash and cash equivalents were $1.2 billion at December 31, 2005 and $556 million at December 31, 2004. At December 31, 2005, the cash and cash equivalent balance included approximately $150 million of cash held in foreign subsidiaries. The Company’s outstanding debt has interest rates ranging from 4.5% to 8.3% and matures at various dates through 2028. Total debt as a percentage of total capital was 29.4% and 32.8% at December 31, 2005 and 2004, respectively.

The Company has approximately $400 million of subordinated notes payable that is scheduled to mature in 2006.

In 2005, the Company exercised its call rights to repurchase long-term debt with a par value of $196 million at a loss of $10 million pretax. In 2004, the Company repurchased long-term debt and subordinated notes payable with a par value of $2,254 million at a loss of $132 million pretax.

In 2003, the Company issued $425 million of long-term debt and used the proceeds to reduce the amounts outstanding under the Company’s lines of credit. Also in 2003, the Company issued $500 million of fixed rate long-term debt and $200 million of floating rate notes and used the proceeds to partially fund the repurchase of long-term debt with a par value of $924 million at a loss of $77 million pre-tax.

In March 2005, the Company entered into a $2.2 billion bank revolving credit facility which replaced its previous $2.3 billion revolving credit facilities. Under the current credit facility, the Company can draw down on lines of credit and use the credit facility to support commercial paper or letters of credit that the Company may issue for short-term liquidity. The credit facility matures in March 2010. Borrowings under the credit facility bear interest based on LIBOR. As of December 31, 2005 and December 31, 2004, there were no borrowings under the current credit facility and the previous credit facilities, respectively; however, the Company had approximately $100 million of outstanding letters of credit at December 31, 2005 and 2004, which effectively reduced the Company’s borrowing capacity under the current credit facility and the previous credit facilities by such amount at such dates.

Under its current credit facility, the Company must comply with certain covenants, including the ratio of total debt to total capitalization of no more than 50% and the ratio of consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA) to consolidated net interest expense, for any period of four consecutive fiscal quarters, of no less than 3.0 to 1.0. The Company was in compliance with the covenants during the period in 2005 in which such credit facility was in place and expects to continue to be in compliance throughout 2006.

Certain foreign subsidiaries of the Company maintain revolving bank lines of credit to provide them with a limited amount of short term liquidity. In 2005, Raytheon United Kingdom Limited, a U.K. subsidiary, entered into a $150 million committed multicurrency revolving credit facility which replaced its previous uncommitted bank lines totaling $84 million. There was $53 million of outstanding borrowings under the facility at December 31, 2005. There were no outstanding borrowings under the bank lines at December 31, 2004. In addition, other uncommitted bank lines totaled $6 million and $7 million at December 31, 2005 and 2004, respectively. There were no amounts outstanding under these lines of credit at December 31, 2005 and 2004, respectively. Compensating balance arrangements are not material.

The Company enters into various interest rate swaps that correspond to a portion of the Company’s fixed rate debt in order to effectively hedge interest rate risk. The $600 million notional value of interest rate swaps that remained outstanding at December 31, 2005 effectively converted that portion of the Company’s total fixed rate debt to variable rate debt based on LIBOR.

Credit ratings for the Company were assigned by Fitch’s at F2 for short-term borrowing and BBB for senior debt, by Moody’s at P-3 for short-term borrowing and Baa3 for senior debt, and by Standard and Poor’s at A-2 for short-term borrowing and BBB for senior debt.

In 2004, in accordance with the terms of the 8.25%, $50 par value equity security units it issued in 2001, the Company issued 27.0 million shares of common stock and received proceeds of $863 million.

The Company has on file a shelf registration with the Securities and Exchange Commission for the issuance of up to $3.0 billion in debt securities, common or preferred stock, warrants to purchase any of the aforementioned securities, and/or stock purchase contracts, under which $1.3 billion remained outstanding at December 31, 2005. The Company expects to use a portion of the remaining availability under the shelf registration in connection with the issuance of common stock warrants in its settlement of the securities class action lawsuit, described in Note L, Commitments and Contingencies of the Notes to the Financial Statements.

In 2004, the Company entered into an agreement to sell certain general aviation finance receivables, with the buyer assuming all servicing responsibilities. As part of the agreement, the Company retained a first loss deficiency guarantee of 7.5% of the receivable amount sold. In 2005 and 2004, the Company sold $5 million and $37 million, respectively, of receivables under the agreement, with no associated gain or loss. Also in 2005 and 2004, the Company separately sold $18 million and $22 million, respectively, of general aviation finance receivables without any continuing involvement.

The Company’s need for, cost of, and access to funds are dependent on future operating results, as well as conditions external to the Company. The Company expects that cash and cash equivalents, cash flow from operations, proceeds from divestitures, and other available financing resources will be sufficient to meet anticipated operating, capital expenditure, and debt service requirements during the next twelve months and for the foreseeable future. In addition, the Company may, from time to time, utilize excess cash balances to repurchase debt or common stock as warranted by market conditions.

The Company has entered into off-balance sheet arrangements, including the sale of general aviation receivables. The Company’s off-balance sheet arrangements are not material to its overall liquidity or capital resources, market risk support or credit risk support. The Company also issues guarantees to third parties related to affiliates as described below in Commitments and Contingencies.

In 2003, the Company sold $337 million of general aviation finance receivables to a qualifying special purpose entity which in turn issued beneficial interests in these receivables to a commercial paper conduit, and retained a subordinated interest in and servicing rights to the receivables. The Company received proceeds of $279 million and recognized a gain of $2 million. The sale was non-recourse to the Company due to third party financial guarantees, and effectively reduced the Company’s exposure to general aviation market risk for receivables by approximately 25%. At December 31, 2005 and 2004, the outstanding balance of securitized accounts receivable held by the third party conduit totaled $157 million and $204 million, respectively, of which the Company’s subordinated retained interest was $59 million and $58 million, respectively, net, and the fair value of the servicing asset was $2 million and $4 million, respectively.

In 1997, the Company provided a first loss guarantee of $133 million on $1.3 billion of U.S. Export-Import Bank loans (maturing in 2015) to the Brazilian government related to the System for the Vigilance of the Amazon (SIVAM) program being performed by the Company’s Network Centric Systems segment. The first interest payment became due and was paid in 2005.

Investments, which are included in other assets, consisted of the following at December 31:

In 2001, the Company formed a joint venture, Thales-Raytheon Systems (TRS), that has two major operating subsidiaries, one of which the Company controls and consolidates. TRS is a system of systems integrator and provides fully customized solutions through the integration of command and control centers, radars, and communication networks. HRL Laboratories is a scientific research facility whose staff engages in the areas of space and defense technologies. TelASIC Communications delivers high performance, cost-effective radio frequency (RF), analog mixed signal, and digital solutions for both the commercial and defense electronics markets.

In 1995, through the acquisition of E-Systems, Inc., the Company invested in Space Imaging and had a 31% equity investment in Space Imaging LLC. In the first quarter of 2003, the Company paid $130 million related to a Space Imaging credit facility that matured in March 2003 for which the Company had guaranteed and accrued for in a prior year. In exchange for this payment, the Company received a note from Space Imaging for this amount that the Company has valued at zero. In January 2006, substantially all of the assets of Space Imaging were sold. The Company received total proceeds of approximately $25 million which will be recorded as other income.

In 2005, the Company sold its investment in Indra ATM S.L., a Spanish joint venture for $59 million and recorded a gain of $45 million in other income, net.

In addition, the Company has entered into joint ventures formed specifically to facilitate a teaming arrangement between two contractors for the benefit of the customer, generally the U.S. government, whereby the Company receives a subcontract from the joint venture in the joint venture’s capacity as prime contractor. Accordingly, the Company records the work it performs for the joint venture as operating activity. Joint ventures are not subject to the Company’s internal control structure.

The Company is involved in various stages of investigation and cleanup related to remediation of various environmental sites. The Company’s estimate of total environmental remediation costs expected to be incurred is $117 million. Discounted at a weighted-average risk-free rate of 5.8%, the Company estimates the liability to be $92 million before U.S. government recovery and had this amount accrued at December 31, 2005. A portion of these costs are eligible for future recovery through the pricing of products and services to the U.S. government. The recovery of environmental cleanup costs from the U.S. government is considered probable based on government contracting regulations and the Company’s long history of receiving reimbursement for such costs. Accordingly, the Company has recorded $51 million at December 31, 2005 for the estimated future recovery of these costs from the U.S. government, which is included in contracts in process. The Company leases certain government-owned properties and is generally not liable for environmental remediation at these sites; therefore, no provision has been made in the financial statements for these costs. Due to the complexity of environmental laws and regulations, the varying costs and effectiveness of alternative cleanup methods and technologies, the uncertainty of insurance coverage, and the unresolved extent of the Company’s responsibility, it is difficult to determine the ultimate outcome of these matters, however, any additional liability is not expected to have a material adverse effect on the Company’s financial position, results of operations, or liquidity.

The Company issues guarantees and has banks and surety companies issue, on its behalf, letters of credit and surety bonds to meet various bid, performance, warranty, retention and advance payment obligations of the Company or its affiliates. Approximately $312 million, $767 million, and $78 million of these guarantees, letters of credit, and surety bonds, for which there were stated values, were outstanding at December 31, 2005, respectively, and $294 million, $827 million, and $250 million were outstanding at December 31, 2004, respectively. These instruments expire on various dates through 2015. Included in guarantees and letters of credit above was $76 million and $183 million at December 31, 2005, respectively and $43 million and $153 million at December 31, 2004, respectively related to the Company’s joint venture in Thales-Raytheon Systems (TRS). Also, included in guarantees, letters of credit, and surety bonds above was $94 million, $8 million, and $62 million at December 31, 2005, respectively and $94 million, $9 million, and $234 million at December 31, 2004, respectively related to discontinued operations. Additional guarantees of project performance for which there is no stated value also remain outstanding.

The Company provides these guarantees and letters of credit to TRS and other affiliates to assist these entities in connection with obtaining financing on more favorable terms, making bids on contracts, and performing their contractual obligations. While the Company expects these entities to satisfy their loans, project performance, and other contractual obligations, their failure to do so may result in a future obligation for the Company.

In connection with the order for 50 Hawker 4000 aircraft received by RAC in 2005, which is subject to the negotiation and execution of a mutually agreeable parent guarantee, RAC will be subject to liquidated damages of approximately $80 million if it fails to deliver at least 30 aircraft in accordance with the terms of the agreement. Under the agreement, RAC is also providing a guaranteed maintenance program which runs for ten years from the delivery date of each Hawker 4000 aircraft and provides for a guaranteed cost of maintenance, subject to annual CPI and other adjustments, for each aircraft. RAC is responsible for any costs that exceed the guaranteed cost of maintenance.

The customers of FO, in certain instances, have the contractual ability to require FO to buy back their fractional share based on its current fair market value. The estimated value of this potential obligation was $575 million and $572 million at December 31, 2005 and 2004, respectively.

Defense contractors are subject to many levels of audit and investigation. Agencies that oversee contract performance include: the Defense Contract Audit Agency, the Department of Defense Inspector General, the Government Accountability Office, the Department of Justice, and Congressional Committees. The Department of Justice, from time to time, has convened grand juries to investigate possible irregularities by the Company. Individually and in the aggregate, these investigations are not expected to have a material adverse effect on the Company’s financial position, results of operations, or liquidity. Raytheon Aircraft is also subject to oversight by the Federal Aviation Administration (the “FAA”). The FAA routinely evaluates aircraft operational and safety requirements and is responsible for certification of new and modified aircraft. Future action by the FAA may adversely affect Raytheon Aircraft’s financial position, results of operations, and liquidity, including recovery of its investment in its newer aircraft.

The following is a schedule of the Company’s contractual obligations outstanding at December 31, 2005:

Interest payments include interest on debt that is redeemable at the option of the Company.

The Company currently estimates that required pension plan cash contributions will be approximately $440 million in 2006. The Company made a discretionary cash contribution of $200 million in January 2006. The estimate for 2006 is subject to change and will not be known with certainty until the status of pension funding reform legislation is finalized in 2006. Estimates for 2007 and beyond have not been provided due to the significant uncertainty of these amounts, which are subject to change with respect to future interest rates, asset returns and pension funding reform. In addition, pension contributions are eligible for future recovery through the pricing of products and services to the U.S. government, therefore, the amounts noted above are not necessarily indicative of the impact these contributions will have on the Company’s liquidity.

Purchase obligations in the table above represent agreements with suppliers to purchase goods or services that are enforceable and legally binding. The Company enters into contracts with customers, primarily the U.S. government, which entitles the Company to full recourse for costs incurred, including purchase obligations, in the event the contract is terminated by the customer for convenience. These purchase obligations are included above notwithstanding the Company’s full recourse.

In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payments (SFAS No. 123R). SFAS No. 123R requires the recognition of compensation expense related to stock options under SFAS No. 123, Accounting for Stock-Based Compensation. In April 2005, the effective date for this accounting standard was deferred until the first annual period beginning after June 15, 2005. The Company expects to adopt SFAS No. 123R prospectively in the first quarter of 2006 with an anticipated impact to earnings per share of less than $0.02 per share for the year 2006.

In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151, an amendment of ARB No. 43, Chapter 4, Inventory Costs (SFAS No. 151). This accounting standard, which is effective for annual periods beginning after June 15, 2005, requires that abnormal amounts of idle facility expense, freight, handling costs, and wasted materials (spoilage) should be recognized as current-period charges. The adoption of SFAS No. 151 is not expected to have a material effect on the Company’s financial position, results of operations, or liquidity.

The Company’s primary market exposures are to interest rates and foreign exchange rates.

The Company meets its working capital requirements with a combination of variable rate short-term and fixed rate long-term financing. The Company enters into interest rate swap agreements with commercial and investment banks to manage interest rates associated with the Company’s financing arrangements. The Company also enters into foreign currency forward contracts with commercial banks to fix the dollar value of commitments and payments to international vendors and the value of foreign currency denominated receipts. The market-risk sensitive instruments used by the Company for hedging are entered into with commercial and investment banks and are directly related to a particular asset, liability, or transaction for which a firm commitment is in place.

Financial instruments held by the Company which are subject to interest rate risk include notes payable, long-term debt, long-term receivables, investments, and interest rate swap agreements. The aggregate hypothetical loss in earnings for one year of those financial instruments held by the Company at December 31, 2005 and 2004, which are subject to interest rate risk resulting from a hypothetical increase in interest rates of 10%, was approximately $2 million and $1 million after-tax for the year ended December 31, 2005 and 2004, respectively. Fixed rate financial instruments were not evaluated, as the risk exposure is not material. The Company believes its exposure due to changes in foreign exchange rates is not material due to the Company’s hedging policy and the fact that the Company does not enter into speculative hedges.

The financial statements and related information contained in this Annual Report have been prepared by and are the responsibility of the Company’s management. The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and reflect judgments and estimates as to the expected effects of transactions and events currently being reported. The Company’s management is responsible for the integrity and objectivity of the financial statements and other financial information included in this Annual Report. To meet this responsibility, the Company maintains a system of internal control over financial reporting to provide reasonable assurance that assets are safeguarded and that transactions are properly executed and recorded. The system includes policies and procedures, internal audits, and Company officers’ reviews.

The Audit Committee of the Board of Directors is composed solely of directors who are independent under applicable SEC and New York Stock Exchange rules. The Audit Committee meets periodically and, when appropriate, separately with representatives of the independent registered public accounting firm, Company officers, and the internal auditors to monitor the activities of each.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, was appointed by the Audit Committee to audit the Company’s financial statements and management’s assessment of the Company’s internal control over financial reporting and their report follows. The stockholders ratified the appointment of PricewaterhouseCoopers LLP at the 2005 Annual Meeting of Stockholders.

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, management has conducted an assessment, including testing, using the criteria in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s system of 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. 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.

Based on its assessment, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2005, based on criteria in Internal Control – Integrated Framework, issued by the COSO. Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included below.

We have completed integrated audits of Raytheon Company’s 2005 and 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2005 and an audit of its 2003 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Raytheon Company and its subsidiaries at December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements 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 the financial statements are free of material misstatement. An audit of financial statements includes 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. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note N to the consolidated financial statements, in 2004 the Company changed its measurement date for its Pension Benefits and Other Benefits plans from October 31 to December 31.

Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 8, that the Company maintained effective internal control over financial reporting as of December 31, 2005 based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control – Integrated Framework issued by the COSO. 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 opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting 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. An audit of internal control over financial reporting includes 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 consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

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.

Principles of Consolidation—The consolidated financial statements include the accounts of Raytheon Company (the “Company”) and all wholly-owned and majority-owned domestic and foreign subsidiaries (except for RC Trust I, as described in Note I, Equity Security Units). All material intercompany transactions have been eliminated. Certain prior year amounts have been reclassified to conform with the current year presentation.

Revenue Recognition—Sales under long-term contracts generally are recorded under the percentage of completion method. Incurred costs and estimated gross margins are recorded as sales when work is performed based on the percentage that incurred costs bear to the Company’s estimates of total costs and contract value. Cost estimates include direct and indirect costs such as labor, materials, warranty, and overhead. Some contracts contain incentive provisions based upon performance in relation to established targets, which are included at estimated realizable value. Contract change orders and claims are included when they can be reliably estimated and realization is considered probable. Since many contracts extend over a long period of time, revisions in cost and contract value estimates during the progress of work have the effect of adjusting earnings applicable to performance in prior periods in the current period. When the current contract estimate indicates a loss, provision is made for the total anticipated loss in the current period. Contracts with multiple elements, primarily license fees, are evaluated and separated, as appropriate, into elements on which revenue is recognized in the proper periods.

Revenue from aircraft sales are recognized at the time of physical delivery of the completed aircraft. Revenue from certain qualifying non-cancelable aircraft lease contracts are accounted for as sales-type leases. The present value of all payments, net of executory costs, are recorded as revenue, and the related costs of the aircraft are charged to cost of sales. Associated interest, using the interest method, is recorded over the term of the lease agreements. All other leases for aircraft are accounted for under the operating method wherein revenue is recorded as earned over the rental period. Service revenue is recognized ratably over contractual periods or as services are performed. Revenue from the sale of fractional shares is recognized over the expected life of the customer relationship.

Revenue from license fees are recognized over the expected life of the continued involvement with the customer.

Lot Accounting—The Company uses lot accounting for new commercial aircraft introductions at Raytheon Aircraft Company (Raytheon Aircraft or RAC). Lot accounting involves selecting an initial lot size at the time a new aircraft begins to be delivered and measuring an average margin over the entire lot for each aircraft sold. The costs attributed to aircraft delivered are based on the estimated average margin of all aircraft in the lot and are determined under the learning curve concept, which anticipates a predictable decrease in unit costs from cost reduction initiatives and as tasks and production techniques become more efficient through repetition. Costs incurred on in-process and delivered aircraft in excess of the estimated average margin were included in inventories and totaled $67 million and $89 million on Premier at December 31, 2005 and 2004, respectively, and $112 million and $90 million on Hawker 4000 at December 31, 2005 and 2004, respectively. Once the initial lot has been completed, the use of lot accounting is discontinued. The Company determines lot size based on several factors, including the size of firm backlog, the expected annual production on the aircraft, and experience on similar new aircraft. The size of the initial lot for the Beechcraft Premier I is 200 units of which 143 had been delivered at December 31, 2005. There was 26 units for the Premier in firm backlog of which 11 units are expected to be delivered from the initial lot. The size of the initial lot for the Hawker 4000 is 75 units, no units had been delivered at December 31, 2005. There was 74 units for the Hawker 4000 in firm backlog of which 34 units are expected to be delivered from the initial lot. At December 31, 2005, deferred costs of $56 million related to Premier and $89 million related to Hawker 4000 were not recoverable from existing firm orders.

Product Warranty—Costs incurred under warranty provisions performed under long-term contracts are accounted for as contract costs as the work is performed. The estimation of these costs is an integral part of the determination of the pricing of the Company’s products and services.

Warranty provisions related to commercial aircraft sales are determined based upon an estimate of costs that may be incurred for warranty services and other post-sales support programs.

Research and Development Expenses—Expenditures for Company-sponsored research and development projects and bid and proposal costs are expensed as incurred. Customer-sponsored research and development projects performed under contracts are accounted for as contract costs as the work is performed.

Federal and Foreign Income Taxes—The Company and its domestic subsidiaries provide for federal income taxes on pretax accounting income at rates in effect under existing tax law. Foreign subsidiaries have recorded provisions for income taxes at applicable foreign tax rates in a similar manner.

Cash and Cash Equivalents—Cash and cash equivalents consist of cash and short-term, highly liquid investments with original maturities of 90 days or less.

Allowance for Doubtful Accounts—The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that will not be collected. The allowance is based upon an assessment of customer credit-worthiness, historical payment experience, the age of outstanding receivables, and collateral to the extent applicable.

Contracts in Process—Contracts in process are stated at cost plus estimated profit, but not in excess of realizable value.

Deferred Contract Costs—Certain costs incurred in the performance of the Company’s government contracts are required to be recorded under generally accepted accounting principles but are not currently allocable to contracts. Such costs include a portion of the Company’s workers’ compensation, environmental expenses, and asset retirement obligations. These costs become allocable to contracts when they are paid, at which time they are charged to contracts and recovered from the government. The Company regularly assesses the probability of recovery of these costs. This assessment requires the Company to make assumptions about the extent of cost recovery under the Company’s contracts and the amount of future contract activity. If the level of backlog in the future does not support the continued deferral of these costs, the profitability of the Company’s remaining contracts could be adversely affected.

Inventories—Inventories are stated at cost (first-in, first-out or average cost), but not in excess of realizable value. A provision for excess or inactive inventory is recorded based upon an analysis that considers current inventory levels, historical usage patterns, future sales expectations, and salvage value.

Property, Plant, and Equipment—Property, plant, and equipment are stated at cost. Major improvements are capitalized while expenditures for maintenance, repairs, and minor improvements are charged to expense. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation and amortization are eliminated from the accounts and any resulting gain or loss is reflected in income. Gains and losses resulting from the sale of plant and equipment at the government and defense businesses are included in overhead and reflected in the pricing of products and services to the U.S. government.

Provisions for depreciation are generally computed using a combination of accelerated and straight-line methods. Depreciation provisions are based on estimated useful lives as follows: buildings—20 to 45 years, machinery and equipment—3 to 10 years, and equipment leased to others—5 to 10 years. Leasehold improvements are amortized over the lesser of the remaining life of the lease or the estimated useful life of the improvement.

Impairment of Goodwill and Long-lived Assets—In accordance with Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets (SFAS No. 142), which addresses financial accounting and reporting for goodwill and other intangible assets, the Company performs periodic tests of goodwill impairment. A two-step impairment test is used to first identify potential goodwill impairment and then measure the amount of goodwill impairment loss, if any. The Company performs the annual impairment test in the fourth quarter of each year. In 2005, the Company recorded a $22 million pretax, $19 million after-tax goodwill impairment charge in administrative and selling expenses related to Flight Options (FO) which is included in the Other segment. The impairment was a result of changes in valuation assumptions, the effect of projecting recent performance variances on future periods and the addition of $28 million in goodwill resulting from the acquisition of the minority shares. If losses at FO were to continue over the longer-term or if FO’s financial objectives were no longer expected to be achieved, the Company’s investment in FO could become further impaired and additional charges may be required. FO must demonstrate substantial operating results improvement to achieve its financial objectives including achieving its sales forecasts, reducing maintenance expense, and improving dispatch availability over the 2005 average. The fair value of FO was estimated using a discounted cash flow methodology since there were no market comparables available. There was no goodwill impairment associated with the annual impairment test performed in the fourth quarter 2005 other than at FO. There was no goodwill impairment in the fourth quarter of 2004 and 2003.

The amount of goodwill by segment at December 31, 2005 was $749 million for Integrated Defense Systems, $1,387 million for Intelligence and Information Systems, $3,438 million for Missile Systems, $2,306 million for Network Centric Systems, $2,674 million for Space and Airborne Systems, $867 million for Technical Services, and $133 million for Other. The amount of goodwill by segment at December 31, 2004 was $755 million for Integrated Defense Systems, $1,349 million for Intelligence and Information Systems, $3,438 million for Missile Systems, $2,306 million for Network Centric Systems, $2,674 million for Space and Airborne Systems, $867 million for Technical Services, and $127 million for Other. Information about additions to goodwill is included in Note C, Acquisitions and Divestitures.

Intangible assets subject to amortization consisted primarily of drawings and intellectual property totaling $63 million (net of $62 million of accumulated amortization) at December 31, 2005 and $74 million (net of $52 million of accumulated amortization) at December 31, 2004. Amortization expense is expected to approximate $13 million for each of the next five years.

In accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, the Company determines whether long-lived assets are to be held-for-use or held-for-disposal. Upon indication of possible impairment, the Company evaluates the recoverability of held-for-use long-lived assets by measuring the carrying amount of the assets against the related estimated undiscounted future cash flows. When an evaluation indicates that the future undiscounted cash flows are not sufficient to recover the carrying value of the asset, the asset is adjusted to its estimated fair value. In order for long-lived assets to be considered held-for-disposal, the Company must have committed to a plan to dispose of the assets. Once deemed held-for-disposal, the assets are stated at the lower of carrying amount or fair value.

Computer Software—Internal use computer software, which consists primarily of an integrated financial package, is stated at cost less accumulated amortization and is amortized using the straight-line method over its estimated useful life, generally 10 years.

Investments—Investments, which are included in other assets, include equity ownership of 20% to 50% in unconsolidated affiliates and of less than 20% in other companies. Investments in unconsolidated affiliates are accounted for under the equity method. Investments in other companies with readily determinable market prices are stated at estimated fair value with unrealized gains and losses included in other comprehensive income. Other investments are stated at cost.

Advance Payments and Billings in Excess of Costs Incurred—The Company receives advances, performance-based payments, and progress payments from customers which may exceed costs incurred on certain contracts.

Comprehensive Income—Comprehensive income and its components are presented in the statement of stockholders’ equity.

Accumulated other comprehensive income consisted of the following at December 31:

The minimum pension liability adjustment is shown net of tax benefits of $1,065 million and $1,089 million at December 31, 2005 and 2004, respectively. The unrealized gains (losses) on interest-only strips are shown net of tax liability of $2 million at December 31, 2005 and net of tax benefits of $1 million at December 31, 2004. The interest rate lock is shown net of tax benefits of $1 million at December 31, 2005 and 2004. The cash flow hedges are shown net of tax liabilities of $2 million and $21 million at December 31, 2005 and 2004, respectively.

Translation of Foreign Currencies—Assets and liabilities of foreign subsidiaries are translated at current exchange rates and the effects of these translation adjustments are reported as a component of accumulated other comprehensive income in stockholders’ equity. Deferred taxes are not recognized for translation-related temporary

differences of foreign subsidiaries as their undistributed earnings are considered to be permanently invested. Income and expenses in foreign currencies are translated at the weighted-average exchange rate during the period. Foreign exchange transaction gains and losses in 2005, 2004, and 2003 were not material.

Pension Costs—The Company has several pension and retirement plans covering the majority of employees, including certain employees in foreign countries. Annual charges to income are made for the cost of the plans, including current service costs, interest on projected benefit obligations, and net amortization and deferrals, increased or reduced by the return on assets. Unfunded accumulated benefit obligations are included in accrued retiree benefits and other long-term liabilities. The Company funds annually those pension costs which are calculated in accordance with Internal Revenue Service regulations and standards issued by the Cost Accounting Standards Board.

Interest Rate and Foreign Currency Contracts—The Company meets its working capital requirements with a combination of variable rate short-term and fixed rate long-term financing. The Company enters into interest rate swap agreements or interest rate locks with commercial and investment banks to manage interest rates associated with the Company’s financing arrangements. The Company also enters into foreign currency forward contracts with commercial banks to fix the dollar value of specific commitments and payments to international vendors and the value of foreign currency denominated receipts. The hedges used by the Company are transaction driven and are directly related to a particular asset, liability, or transaction for which a commitment is in place. These instruments are executed with credit-worthy institutions and the majority of the foreign currencies are denominated in currencies of major industrial countries. The Company does not hold or issue financial instruments for trading or speculative purposes.

Fair Value of Financial Instruments—The estimated fair value of certain financial instruments, including cash, cash equivalents, and short-term debt approximates the carrying value due to their short maturities and varying interest rates. The estimated fair value of notes receivable approximates the carrying value based principally on the underlying interest rates and terms, maturities, collateral, and credit status of the receivables. The estimated fair value of investments, other than those accounted for under the cost or equity method, are based on quoted market prices. The estimated fair value of long-term debt of approximately $4.7 billion at December 31, 2005 was based on quoted market prices.

Estimated fair values for financial instruments are based on pricing models using current market information. The amounts realized upon settlement of these financial instruments will depend on actual market conditions during the remaining life of the instruments.

Minority Interest—The Company’s minority interest primarily relates to its investment in Thales-Raytheon Systems Co. Ltd., described in Note G, Other Assets.

Employee Stock Plans—In 2004, the Company changed the primary form of its broad-based equity compensation from stock options to restricted stock. The fair value at the date of award of restricted stock is credited to common stock at par value and the excess is credited to additional paid-in capital. The fair value is charged to income as compensation expense over the vesting period.

In 2004, the Company established the Long-Term Performance Plan (LTPP) which provides for restricted stock unit awards granted from the 2001 Stock Plan to the Company’s senior leadership. These awards vest when specific pre-established levels of Company performance are achieved over a three-year performance cycle. The Company recognizes compensation expense for variable award plans over the performance period based upon the then-current market values of the underlying stock as well as the expected achievement of performance levels.

The Company applies Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations, in accounting for its stock-based compensation plans. Accordingly, because stock options were issued at exercise prices equal to fair value, no compensation expense has been recognized for the Company’s stock option plans, however, stock-based compensation expense has been recorded for restricted stock and the LTPP. Proceeds

from the exercise of stock options under employee stock plans are credited to common stock at par value and the excess is credited to additional paid-in capital. Income tax benefits arising from employees’ premature disposition of stock option shares and exercise of nonqualified stock options are credited to additional paid-in capital.

Had compensation expense for the Company’s stock-based compensation been determined based on the fair value at the grant date for awards under these plans, consistent with the methodology prescribed under Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation, the Company’s net income and earnings per share would have approximated the pro forma amounts indicated below:

The weighted-average fair value of each stock option granted in 2005, 2004, and 2003 was estimated as $8.44, $8.70, and $8.57, respectively, on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

The risk free interest rate (month-end yields on 4-year treasury strips equivalent zero coupon) was 3.6% in 2005, and ranged from 2.4% to 3.6% in 2004 and 2.0% to 3.0% in 2003.

Accounting Standards—In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payments (SFAS No. 123R). SFAS No. 123R requires the recognition of compensation expense related to stock options under SFAS No. 123, Accounting for Stock-Based Compensation. In April 2005, the effective date for this accounting standard was deferred until the first annual period beginning after June 15, 2005. The Company expects to adopt SFAS No. 123R prospectively in the first quarter of 2006 with an anticipated impact to earnings per share of less than $0.02 per share for the year 2006.

Risks and Uncertainties—The Company is engaged in supplying defense-related equipment to the U.S. and foreign governments, and is subject to certain business risks specific to that industry. Sales to the government may be affected by changes in procurement policies, budget considerations, changing concepts of national defense, political developments abroad, and other factors.

The highly competitive market for business and special mission aircraft is also subject to certain business risks. These risks include timely development and certification of new product offerings, the current state of the general aviation and commuter aircraft markets, and government regulations affecting aircraft.

The Company’s consolidated financial statements are based on the application of generally accepted accounting principles which require the Company to make estimates and assumptions about future events that affect the amounts reported in its financial statements and the accompanying notes. Future events and their effects can not be determined with certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from those estimates, and any such differences may be material to the Company’s financial statements.

The Company is currently engaged in a dispute with AES Red Oak LLC (AES) over the close out of the Red Oak power project. The dispute involves, among other things, a draw down of $30 million by AES in August 2004 from a line of credit provided by the Company.

The after-tax loss from discontinued operations related to RE&C was $50 million, $48 million, and $151 million in 2005, 2004, and 2003, respectively.

Liabilities from discontinued operations included net current liabilities for RE&C of $33 million and $17 million at December 31, 2005 and 2004, respectively.

In 2005, 2004, and 2003, the pretax loss from discontinued operations related to AIS was $33 million, $23 million and $30 million, respectively, primarily related to the completion of the BBJ program and the resolution of the purchase price dispute.

Assets and liabilities related to AIS included net current assets of $19 million as of December 31, 2004 and net current liabilities of $16 million and $7 million as of December 31, 2005 and 2004, respectively.

In 2005, the total loss from discontinued operations was $74 million pretax, $71 million after-tax, or $0.16 per basic and diluted share versus $65 million pretax, $63 million after-tax, or $0.14 per basic and diluted share in 2004 and $261 million pretax, $170 million after-tax, or $0.41 per basic and diluted share in 2003.

In August 2005, the Company acquired UTD, Inc. for $39 million, net of cash received, subject to a purchase price adjustment. The Company recorded $2 million of intangible assets and $36 million of goodwill (at Intelligence and Information Systems) in connection with this acquisition.

In 2004, the Company acquired Photon Research Associates Inc. for $42 million, net of cash received. In addition, the Company may be required to make certain performance-based incentive payments. Assets acquired included $5 million of contracts in process, $1 million of property, plant and equipment, and $1 million of other assets. Liabilities assumed included $2 million of accrued salaries and wages and $3 million of other accrued liabilities. The Company also recorded $5 million of intangible assets and $35 million of goodwill (at Space and Airborne Systems) in connection with this acquisition.

In 2004, the Company sold its commercial infrared business for $43 million and recorded a pretax gain of $10 million which was included in other income.

In 2003, the Company acquired Solipsys Corporation for $170 million, net of cash received, to be paid over two years. The Company made cash payments of $60 million in 2005, $70 million in 2004 and $40 million in 2003 related to this acquisition. In addition, the Company may be required to make certain performance-based incentive payments. Assets acquired included $7 million of contracts in process. Liabilities assumed included $2 million of accounts payable and $3 million of accrued salaries and wages. The Company also recorded $8 million of intangible assets and $160 million of goodwill (at Integrated Defense Systems) in connection with this acquisition.

In 2003, the Company acquired the Aerospace and Defence Services business unit of Honeywell International Inc. for $20 million in cash. Assets acquired included $4 million of contracts in process. Liabilities assumed included $1 million of accounts payable and $2 million of other accrued expenses. The Company also recorded $8 million of intangible assets and $11 million of goodwill (at Technical Services) in connection with this acquisition.

Pro forma financial information has not been provided for these acquisitions as they are not material either individually or in the aggregate. In addition, the Company has entered into other acquisition and divestiture agreements in the normal course of business that have not been separately disclosed as they are not material.

In 2002, the Company formed a joint venture with Flight Options, Inc. whereby the Company contributed its Raytheon Travel Air fractional ownership business and loaned the new entity $20 million. In June 2003, the Company participated in a financial recapitalization of Flight Options LLC (FO) and exchanged certain FO debt for equity. In December 2005, the Company settled all disputes with the FO minority shareholders and acquired the minority shares for $28 million in cash and assumed liabilities and now owns 100% of FO. Employees of FO own an insignificant amount of FO stock and stock options.

The U.S. government has title to the assets related to unbilled amounts on contracts that provide for progress payments. Unbilled amounts are recorded under the percentage of completion method and are recoverable from the customer upon shipment of the product, presentation of billings, or completion of the contract.

Included in contracts in process at December 31, 2005 and 2004 was $27 million and $66 million, respectively, related to claims on contracts, which were recorded at their estimated realizable value. The Company believes that it has a legal basis for pursuing recovery of these claims and that collection is probable. The settlement of these amounts depends on individual circumstances and negotiations with the counterparty, therefore, the timing of the collection will vary and approximately $11 million of collections are expected to extend beyond one year.

Billed and unbilled contracts in process include retentions arising from contractual provisions. At December 31, 2005, retentions amounted to $36 million and are anticipated to be collected as follows: $26 million in 2006 and the balance thereafter.

Inventories at Raytheon Aircraft, Flight Options, and Raytheon Airline Aviation Services totaled $1,411 million at December 31, 2005 (consisting of $475 million of finished goods, $742 million of work in process, and $194 million of materials and parts) and $1,420 million at December 31, 2004 (consisting of $537 million of finished goods, $681 million of work in process, and $202 million of materials and parts). Inventories at the government and defense businesses include component parts, materials, and amounts incurred in advance of contract funding.

Depreciation expense was $354 million, $361 million, and $333 million in 2005, 2004, and 2003, respectively. Accumulated depreciation of equipment leased to others was $28 million and $29 million at December 31, 2005 and 2004, respectively.

General and program specific manufacturing equipment and tooling at Raytheon Aircraft are included in property, plant, and equipment. There was $191 million and $205 million of program specific manufacturing equipment and tooling related to Premier and Hawker 4000 at December 31, 2005 and 2004, respectively.

Future minimum lease payments from non-cancelable aircraft operating leases, which extend to 2018, amounted to $120 million at December 31, 2005 and were due as follows:

The Company provides long-term financing to its aircraft customers. The underlying aircraft serve as collateral for general aviation and commuter aircraft receivables. The Company maintains reserves for estimated uncollectible aircraft-related long-term receivables. The balance of these reserves was $13 million and $28 million at December 31, 2005 and 2004, respectively. The reserves for estimated uncollectible aircraft-related long-term receivables represent the Company’s current estimate of future losses. The Company established these reserves based on an overall evaluation of identified

risks. As a part of that evaluation, the Company evaluated certain specific receivables and considered factors including extended delinquency and requests for restructuring, among other things. Long-term receivables included commuter aircraft receivables of $228 million and $281 million at December 31, 2005 and 2004, respectively.

The Company accrues interest on aircraft-related long-term receivables in accordance with the terms of the underlying notes. When an aircraft-related long-term receivable is over 90 days past due, the Company generally stops accruing interest. At December 31, 2005 and 2004, there were $7 million and $27 million, respectively, of aircraft-related long-term receivables on which the Company was not accruing interest. Interest payments related to these receivables are credited to income when received. Once a past-due receivable has been brought current, the Company begins to accrue interest again. Interest deemed to be uncollectible is written off at the time the determination is made.

In 2004, the Company entered into an agreement to sell certain general aviation finance receivables, with the buyer assuming all servicing responsibilities. As part of the agreement, the Company retained a first loss deficiency guarantee of 7.5% of the receivable amount sold. In 2005 and 2004, $5 million and $37 million, respectively, of receivables were sold under the agreement, with no associated gain or loss. Also in 2005 and 2004, the Company sold $18 million and $22 million, respectively, of general aviation finance receivables without any continuing involvement.

In 2003, the Company sold an undivided interest in $337 million of general aviation finance receivables, while retaining a subordinated interest in and servicing rights to the receivables. The Company received proceeds of $279 million and recognized a gain of $2 million. In connection with the sale, the Company formed a qualifying special purpose entity (QSPE) for the sole purpose of buying these receivables. The Company irrevocably, and without recourse, transferred the receivables to the QSPE which in turn, issued beneficial interests in these receivables to a commercial paper conduit. The transaction involves a third party guarantee of the conduit investment. The assets of the QSPE are not available to pay the claims of the Company or any other entity. The Company retained a subordinated interest in the receivables sold of approximately 17%. The conduit obtained the funds to purchase the interest in the receivables, other than the retained interest, by selling commercial paper to third-party investors. The Company retained responsibility for the collection and administration of receivables. The Company continues to service the sold receivables and charges the third party conduit a monthly servicing fee at market rates.

The Company accounted for the sale under Statement of Financial Accounting Standards No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities. The gain was determined at the date of transfer based upon the relative fair value of the assets sold and the interests retained. The Company estimated the fair value at the date of transfer and at December 31, 2005 and 2004 based on the present value of future expected cash flows using certain key assumptions, including collection period and a discount rate of 5.0%, 6.2%, and 5.6%, respectively. At December 31, 2005 a 10 and 20% adverse change in the collection period and discount rate would not have a material effect on the Company’s financial position or results of operations.

At December 31, 2005 and 2004, the outstanding balance of securitized accounts receivable held by the third party conduit totaled $157 million and $204 million, respectively, of which the Company’s subordinated retained interest was $59 million and $58 million, respectively, and the fair value of the servicing asset was $2 million and $4 million, respectively.

Computer software amortization expense was $77 million, $64 million, and $52 million in 2005, 2004 and 2003, respectively. Accumulated amortization of computer software was $327 million and $261 million at December 31, 2005 and 2004, respectively.

Investments, which are included in other assets, consisted of the following at December 31:

In 2001, the Company formed a joint venture, Thales-Raytheon Systems (TRS) that has two major operating subsidiaries, one of which the Company controls and consolidates. TRS is a system of systems integrator and provides fully customized solutions through the integration of command and control centers, radars, and communication networks. HRL Laboratories is a scientific research facility whose staff engages in the areas of space and defense technologies. TelASIC Communications delivers high performance, cost-effective radio frequency (RF), analog mixed signal, and digital solutions for both the commercial and defense electronics markets.

In 2005, the Company sold its interest in Indra ATM S.L., a Spanish joint venture, for $59 million, and recorded a gain of $45 million.

Certain joint ventures and equity and cost method investments are not listed separately in the table above as the Company’s investment in these entities is less than $5 million. Information for these joint ventures and investments has not been separately disclosed since they are not material either individually or in the aggregate.

The notes and debentures redeemable at any time are at redemption prices equal to the present value of remaining principal and interest payments. Information about the subordinated notes payable is included in Note I, Equity Security Units.

The debentures due in 2025 were redeemable at the option of the Company on or after July 15, 2005 at a redemption price of 103% of par. In 2005, the Company exercised its call rights to repurchase all of these debentures, with a par value of $196 million, at a loss of $10 million pretax.

In 2004, the Company repurchased long-term debt with a par value of $1,773 million at a loss of $100 million pretax which was included in other expense.

In 2003, the Company issued $425 million of long-term debt and used the proceeds to reduce the amounts outstanding under the Company’s lines of credit. Also in 2003, the Company issued $500 million of fixed rate long-term debt and $200 million of floating rate notes. The proceeds were used to partially fund the repurchase of long-term debt with a par value of $924 million at a loss of $77 million pretax, which was included in other expense.

The Company enters into various interest rate swaps that correspond to a portion of the Company’s fixed rate debt in order to effectively hedge interest rate risk. The $600 million notional value of the interest rate swaps that remained outstanding at December 31, 2005 effectively converted that portion of the Company’s total fixed rate debt to variable rate debt based on LIBOR.

The principal amounts of long-term debt were reduced by debt issue discounts of $58 million and $81 million at December 31, 2005 and 2004, respectively and interest rate hedging costs of $36 million and $54 million, at December 31, 2005 and 2004, respectively, on the date of issuance, and are reflected as follows at December 31:

The aggregate amounts of principal payments due on long-term debt and subordinated notes payable for the next five years are:

Total cash paid for interest on notes payable and long-term debt was $310 million, $396 million, and $515 million in 2005, 2004, and 2003, respectively.

In 2001, the Company issued 17,250,000, 8.25%, $50 par value equity security units. Each equity security unit consisted of a contract to purchase shares of the Company’s common stock on May 15, 2004 and a mandatorily redeemable equity security with a stated liquidation amount of $50 due on May 15, 2006.

In 2004, in accordance with the terms of the equity security units, the Company issued 27.0 million shares of common stock and received proceeds of $863 million. The contract required a quarterly distribution, which was recorded as a reduction to additional paid-in capital, of 1.25% per year of the stated amount of $50 per purchase contract. Cash paid for the quarterly distribution on the contract was $4 million in 2004 and $11 million in 2003. The mandatorily redeemable equity security represents preferred stock of RC Trust I (RCTI), a subsidiary of the Company that initially issued this preferred stock to the Company in exchange for a subordinated note. The subordinated notes ($408 million at December 31, 2005 and 2004), which are due on May 15, 2006, have the same terms as the mandatorily redeemable equity security and represent an undivided interest in the assets of RCTI, a Delaware business trust formed for the purpose of issuing these securities and whose assets consist solely of subordinated notes issued by the Company. The subordinated notes pay a quarterly distribution, which was included in interest expense, of 7.0% per year. Cash paid for the quarterly distribution on the subordinated notes was $27 million in 2005, $47 million in 2004 and $60 million in 2003. In 2004, subordinated notes with a par value of $481 million were repurchased at a loss of $32 million pretax, which was included in other expense.

RCTI is considered to be a variable interest entity and because the preferred stock was a part of the equity security units issued by the Company, the Company is not considered the primary beneficiary of RCTI. As a result, RCTI is not consolidated by the Company. The Company has a $27 million investment in RCTI which represents all of the common stock of RCTI and is included in other noncurrent assets. The Company owes $27 million to RCTI (included in subordinated notes payable) in connection with this investment.

On November 30, 2004, the Board of Directors authorized the repurchase, between January 1, 2005 and December 31, 2006, of up to $700 million of the Company’s common stock. In 2005, the Company repurchased 11.2 million shares of common stock for $436 million under this program.

The Company issued 2,325,000 and 6,486,000 shares of common stock in 2004 and 2003, respectively, to fund the Company Match and Company Contributions, as described in Note N, Pension and Other Employee Benefits. In addition, employee-directed 401(k) plan purchases (Employee Contributions) of the Company stock fund were funded through the issuance of 134,000 and 2,491,000 shares of common stock in 2004 and 2003, respectively.

Basic earnings per share (EPS) is computed by dividing net income by the weighted-average shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity.

The weighted-average shares outstanding for basic and diluted EPS were as follows:

Stock options to purchase 16.5 million, 18.7 million, and 30.6 million shares of common stock outstanding at December 31, 2005, 2004, and 2003, respectively, did not affect the computation of diluted EPS. The exercise prices for these options were greater than the average market price of the Company’s common stock during the respective years.

Stock options to purchase 17.2 million, 19.5 million, and 15.3 million shares of common stock outstanding at December 31, 2005, 2004, and 2003, respectively, had exercise prices that were less than the average market price of the Company’s common stock during the respective periods and are included in the dilutive effect of stock options, restricted stock, LTPP and equity security units in the table above.

The Board of Directors is authorized to issue up to 200,000,000 shares of preferred stock, $0.01 par value per share, in multiple series with terms as determined by the Board of Directors.

As discussed in Commitments and Contingencies, the terms of the settlement of the securities class action lawsuit include the issuance of warrants for the Company’s stock with a stipulated value of $200 million. The warrants will have a five-year term with a strike price of $37.50 and will be issued when the settlement proceeds are distributed to the claimants which is expected to occur in the second quarter of 2006.

The provision (benefit) for state income taxes of $8 million, $6 million, and $(1) million in 2005, 2004, and 2003, respectively, was included in administrative and selling expenses as these costs can generally be recovered through the pricing of products and services to the U.S. government in the period for which the tax is payable. Accordingly, the deferred state income tax provision (benefit), which is not material, will be allocated to contracts in future periods as they are realized.

The provision for income taxes differs from the U.S. statutory rate due to the following:

In 2005, 2004, and 2003, domestic income before taxes was $1,364 million, $559 million, and $754 million, respectively, and foreign income before taxes was $76 million, $20 million, and $8 million, respectively. Income reported for federal and foreign tax purposes differs from pretax accounting income due to differences between U.S. Internal Revenue Code or foreign tax law requirements and the Company’s accounting practices. No provision has been made for deferred taxes on undistributed earnings of non-U.S. subsidiaries as these earnings have been indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability on these undistributed earnings is not practicable. Total net cash payments were approximately $56 million, $5 million, and $13 million in 2005, 2004, and 2003, respectively.

The Company is currently under examination by the Internal Revenue Service (IRS) for the years 1998 through 2002. IRS examinations have been completed for tax years through 1997. The Company has protested certain positions taken by the IRS examination team on certain items related to the years 1995 through 1997 and those items are now being considered by the Appeals Division (Appeals) of the IRS.

In addition, the Company’s federal research tax credit refund claim for the years 1984 through 1990 remains under examination, and certain items regarding the Company’s Foreign Sales Corporation (FSC) benefit for the years 1989 through 1997 are also at Appeals. The Company believes adequate provisions for all outstanding issues have been made for all open years.

Amounts accrued for potential tax assessments totaled $247 million at December 31, 2005 and were recorded in non-current liabilities. Amounts accrued at December 31, 2004 totaled $225 million. Accruals relate to U.S. federal tax matters and taxation of foreign earnings and include items such as the tax benefits from the FSC and Extraterritorial Income (ETI) regimes, the amount of research tax credits, allocation of income among various tax jurisdictions, issues related to various acquisitions and divestitures, and various other federal and foreign tax issues. Amounts asserted by taxing authorities could be greater than the Company’s accrued position. Accordingly, additional provisions on federal and foreign tax related matters could be recorded in the future as revised estimates are made or the underlying matters are settled.

The American Jobs Creation Act of 2004 (the “Act”) repealed and provided transitional relief for the ETI regime for transactions after December 31, 2004. The Act also provides a deduction for income derived from qualifying domestic production activities that is phased in over the 2005 – 2010 period. The deduction is equal to 3% of qualifying income in 2005 and 2006, 6% in 2007, 2008, and 2009, and 9% thereafter. The introduction of legislation proposing a technical correction to the Act accompanied by language in recently issued proposed regulations consistent with the technical correction have substantially diminished concerns existing in prior periods that U.S. government contractors might be denied full benefits under the domestic production activities incentive. The Act also extended the carryover period for foreign tax credits from 5 to 10 years and reinstated the research and development tax credit. The Company recorded a tax benefit of $42 million in 2004 primarily related to the extension of the carryover period.

In addition, the Act creates a temporary incentive for U.S. corporations to repatriate accumulated income earned abroad by providing a deduction for certain dividends from controlled foreign corporations equivalent to 85% of the dividends received. The Company recorded a $5 million tax expense in 2005 in connection with a repatriation of $110 million completed pursuant to the Act.

Deferred federal and foreign income taxes consisted of the following at December 31:

There were $3 million of taxes refundable included in prepaid expenses and other current assets at December 31, 2005 and 2004. Federal tax (expenses) benefits related to discontinued operations were $2 million and $(20) million at December 31, 2005 and 2004, respectively, and were included in deferred federal and foreign income taxes in the table above.

At December 31, 2005, the Company had foreign tax credit carryforwards of $90 million that expire in 2009 through 2015, research tax credit carryforwards of $37 million that expire in 2018 through 2025, and alternative minimum tax credit carryforwards of $32 million that are carried forward indefinitely. The Company believes it will be able to utilize substantially all of these carryforwards over the next 4 to 5 years.

At December 31, 2005, the Company had commitments under long-term leases requiring annual rentals on a net lease basis as follows:

Rent expense in 2005, 2004, and 2003 was $280 million, $266 million, and $263 million, respectively. In the normal course of business, the Company leases equipment, office buildings, and other facilities under leases that include standard escalation clauses for adjusting rent payments to reflect changes in price indices, as well as renewal options.

At December 31, 2005, the Company had commitments under an agreement to outsource a significant portion of its information technology function requiring minimum annual payments as follows:

In connection with certain aircraft sales, the Company has offered trade-in incentives whereby the customer will receive a pre-determined trade-in value if they purchase another aircraft from the Company. The difference between the value of these trade-in incentives, the majority of which expire by the end of 2008, and the current estimated fair value of the underlying aircraft was approximately $4 million at December 31, 2005. There is a high degree of uncertainty inherent in the assessment of the likelihood and value of trade-in commitments.

The Company self-insures for losses and expenses for aircraft product liability up to a maximum of $10 million per occurrence and $50 million annually. Insurance is purchased from third parties to cover excess aggregate liability exposure from $50 million to $1.25 billion. This coverage also includes the excess of liability over $10 million per occurrence. The aircraft product liability reserve was $33 million and $38 million at December 31, 2005 and 2004, respectively.

The Company is involved in various stages of investigation and cleanup related to remediation of various environmental sites. The Company’s estimate of total environmental remediation costs expected to be incurred is $117 million. Discounted at a weighted-average risk-free rate of 5.8%, the Company estimates the liability to be $92 million before U.S. government recovery and had this amount accrued at December 31, 2005. A portion of these costs are eligible for future recovery through the pricing of products and services to the U.S. government. The recovery of environmental cleanup costs from the U.S. government is considered probable based on government contracting regulations and the Company’s long history of receiving reimbursement for such costs. Accordingly, the Company has recorded $51 million at December 31, 2005 for the estimated future recovery of these costs from the U.S. government, which is included in contracts in process. The Company leases certain government-owned properties and is generally not liable for environmental remediation at these sites, therefore, no provision has been made in the financial statements for these costs. Due to the complexity of environmental laws and regulations, the varying costs and effectiveness of alternative cleanup methods and technologies, the uncertainty of insurance coverage, and the unresolved extent of the Company’s responsibility, it is difficult to determine the ultimate outcome of these matters, however, any additional liability is not expected to have a material adverse effect on the Company’s financial position, results of operations, or liquidity.

The customers of Flight Options (FO), in certain instances, have the contractual ability to require FO to buy back their fractional share based on its current fair market value. The estimated value of this potential obligation was $575 million and $572 million at December 31, 2005 and 2004, respectively.

As previously reported, the Company has been cooperating with the staff of the Securities and Exchange Commission (the “SEC”) in a formal investigation into the Company’s disclosure and accounting practices, primarily related to the commuter aircraft business and the timing of revenue recognition at Raytheon Aircraft during the period from 1997 to 2001. On April 15, 2005, the Company announced that it had submitted an offer of settlement to the staff of the SEC, which the staff agreed to recommend to the SEC. The Company, without admitting or denying any wrongdoing, offered to pay a civil penalty of $12 million and consent to the entry of a cease and desist order with respect to violations of Sections 17(a)(2)-(3) of the Securities Act of 1933 and Sections 13(a) and 13(b)(2)(A)-(B) of the Securities Exchange Act of 1934, and related SEC rules. The proposed settlement is subject to approval by the SEC.

In May 2004, without admitting any liability or wrongdoing, the Company reached an agreement to settle a securities class action lawsuit originally filed in 1999 on behalf of the Company and all individual defendants. The terms of the settlement include a cash payment of $210 million and the issuance of warrants for the Company’s stock with a stipulated value of $200 million. The warrants will have a five-year term with a strike price of $37.50 and will be issued when the settlement proceeds are distributed to the claimants which is expected to occur in the second quarter of 2006. In December 2004, the court approved the settlement, resolving all claims asserted against the Company and the individual defendants. In connection with the settlement, the Company recorded a charge of $329 million in 2004, of which $325 million was included in other expense, a $410 million accrued expense, and an $85 million receivable for insurance proceeds primarily related to this settlement. The charge for the settlement will be revised to reflect the actual fair value of the warrants upon issuance. In 2004, the Company paid $210 million into escrow in connection with the settlement. In 2005, the insurance receivable balance was paid in full. In July 2004, without admitting any liability or wrongdoing, the Company and the individual defendants reached an agreement to settle a derivative action related to this class action lawsuit for $4 million. The settlement, which was approved by the court in July 2005, resolves all claims in the case.

In May 2005, without admitting any liability or wrongdoing, the Company and individual defendants reached an agreement to settle a class action lawsuit originally filed in 2001. The settlement includes a cash payment by the Company of $39 million, which was paid into escrow in May 2005. In July 2005, the court approved the settlement which resolves all claims in the case. In November 2005, the Company received approximately $28 million from its insurance carriers towards the settlement and related expenses. In November 2004, without admitting any liability or wrongdoing, the individual defendants and the Company reached a tentative agreement to settle a derivative action related to this class action lawsuit for $2 million. The settlement, which was approved by the court in September 2005, resolves all claims in the case.

In May 2003, two purported class action lawsuits were filed on behalf of participants in the Company’s savings and investment plans who invested in the Company’s stock between August 19, 1999 and May 27, 2003. The two class action complaints are brought pursuant to the Employee Retirement Income Security Act (ERISA). Both lawsuits are substantially similar and have been consolidated into a single action. In April 2004, a second consolidated amended complaint (the “Second Consolidated Amended ERISA Complaint”) was filed on behalf of participants and beneficiaries in the Company’s savings and investment plans who invested in the Company’s stock since October 7, 1998. The Second Consolidated Amended ERISA Complaint alleges that the Company, its Pension and Investment Group, and its Investment Committee breached ERISA fiduciary duties by failing to: (1) prudently and loyally manage plan assets, (2) monitor the Pension and Investment Group and the Investment Committee and provide them with accurate information, (3) provide complete and accurate information to plan participants and beneficiaries, and (4) avoid conflicts of interest. In October 2004, the defendants filed a motion to dismiss the Second Consolidated Amended ERISA Complaint. In September 2005, the court heard the motion to dismiss but declined to decide the motion subject to a trial on a statute of limitations issue, which is scheduled for June 2006. Although the Company believes that it and the other defendants have meritorious defenses and intends to contest this lawsuit vigorously, an adverse resolution of this lawsuit could have a material adverse effect on the Company’s financial position, results of operations, and liquidity. The Company is not presently able to reasonably estimate potential losses, if any, related to this lawsuit.

In addition, various claims and legal proceedings generally incidental to the normal course of business are pending or threatened against the Company. While the ultimate liability or potential range of loss, if any, from these proceedings is presently indeterminable, any additional liability is not expected to have a material adverse effect on the Company’s financial position, results of operations, or liquidity.

The 2001 Stock Plan and 1995 Stock Option Plan provide for the grant of both incentive and nonqualified stock options at an exercise price which is not less than 100% of the fair value on the date of grant. The 1991 Stock Plan provided for the grant of incentive stock options at an exercise price which was 100% of the fair value on the date of grant and nonqualified stock options at an exercise price which may have been less than the fair value on the date of grant. The 1976 Stock Option Plan provided for the grant of both incentive and nonqualified stock options at an exercise price which was 100% of the fair value on the date of grant. No further grants are allowed under the 1995 Stock Plan, 1991 Stock Plan or 1976 Stock Option Plan. All of these plans were approved by the Company’s stockholders.

Stock options granted under the plans may generally be exercised in their entirety from 1 to 6 years after the date of grant. Incentive stock options terminate 10 years from the date of grant, and those stock options granted after December 31, 1986 become exercisable to a maximum of $100,000 per year. Nonqualified stock options terminate 11 years from the date of grant, 10 years and a day if issued in connection with the 1995 Stock Option Plan, or as determined by the Management Development and Compensation Committee of the Board of Directors (MDCC) if issued under the 2001 Stock Plan.

Awards of restricted stock units under the Company’s LTPP will be made from the 2001 Stock Plan. The performance goals for both the 2004 – 2006 LTPP and the 2005 – 2007 LTPP are independent of each other and equally weighted, and are based on two metrics: free cash flow, as defined, and total shareholder return relative to a peer group both over a three-year period. The ultimate award, which is determined at the end of the three-year performance cycle, can range from zero to 200% of the target award. The target award outstanding at December 31, 2005 related to 2005 and 2004 was 473,500 units and 573,800 units, respectively. The amount of compensation expense recorded was $15 million in 2005 and $8 million in 2004.

The 2001 Stock Plan also provides for the award of restricted stock, restricted stock units and stock appreciation rights. The 1997 Nonemployee Directors Restricted Stock Plan provides for the award of restricted stock to nonemployee directors. Awards of restricted stock, restricted stock units, and stock appreciation rights are made by the MDCC and are compensatory in nature. These awards vest over a specified period of time as determined by the MDCC, generally 4 years. Restricted stock awards entitle the recipient to full dividend and voting rights. Unvested shares are restricted as to disposition and subject to forfeiture under certain circumstances.

No further grants are allowed under the 2001 Stock Plan or the 1997 Nonemployee Directors Restricted Stock Plan after January 30, 2011 and November 25, 2011, respectively.

Awards of 2,098,500, 1,875,600, and 314,800 shares of restricted stock and restricted stock units were made to employees and non-employee directors at a weighted-average fair value at the grant date of $39.04, $35.08, and $30.02 in 2005, 2004, and 2003, respectively. The required conditions for 227,500, 446,100, and 200,100 shares of restricted stock and restricted units were satisfied during 2005, 2004, and 2003, respectively. There were 115,100; 122,900; and 13,000 shares of restricted stock forfeited during 2005, 2004, and 2003, respectively. There were 4,003,100, 2,247,300, and 940,600 shares of restricted stock and restricted stock units outstanding at December 31, 2005, 2004, and 2003, respectively. The amount of compensation expense recorded was $45 million, $16 million, and $8 million in 2005, 2004, and 2003, respectively.

There were 47.8 million, 46.6 million, and 53.2 million additional shares of common stock (including shares held in treasury) authorized for stock option, restricted stock, and restricted stock unit awards at December 31, 2005, 2004, and 2003, respectively.

The following tables summarize information about stock options outstanding and exercisable at December 31, 2005:

Shares exercisable at the corresponding weighted-average exercise price at December 31, 2005, 2004, and 2003, were 30.4 million at $41.14, 30.0 million at $40.81, and 30.1 million at $41.49, respectively.

The Company has pension plans covering the majority of its employees, including certain employees in foreign countries (Pension Benefits). In addition to providing pension benefits, the Company provides certain health care and life insurance benefits to retired employees through other postretirement benefit plans (Other Benefits). Substantially all of the Company’s U.S. employees may become eligible for the Other Benefits. Effective January 1, 2004, the Company changed the measurement date for its Pension Benefits and Other Benefits plans from October 31 to December 31. This change in measurement date was accounted for as a change in accounting principle. The cumulative effect of this change in accounting principle was a gain of $53 million pretax for Pension Benefits and a gain of $10 million pretax for Other Benefits. Using the Company’s year end as the measurement date for Pension Benefits and Other Benefit plans more appropriately reflects the plans’ financial status for the years then ended. In 2004, the total cumulative effect of the change in accounting principle was a gain of $63 million pretax, $41 million after-tax, or $0.09 per basic and diluted share.

The following adjusts reported income from continuing operations and basic and diluted earnings per share (EPS) from continuing operations as if the change in accounting principle had been applied prior to the periods presented:

The following adjusts reported net income and basic and diluted earnings per share (EPS) as if the change in accounting principle had been applied prior to the periods presented:

The strategic asset allocation of the Company’s domestic Pension Benefits and Other Benefits plans is diversified with an average and moderate level of risk consisting of investments in equity securities (including domestic and international equities and the Company’s common stock), debt securities, real estate, and other areas such as private equity and cash. The Company seeks to produce a return on investment over the long-term commensurate with levels of investment risk which are prudent and reasonable given the prevailing capital market expectations. Policy range allocations are 50 to 75% for equity securities, 20 to 40% for debt securities, 2 to 7% for real estate, and 2 to 17% for other areas. The long-term return on asset assumption for the Company’s domestic Pension Benefits and Other Benefits plans for 2006 is 8.75%. The long-term return on asset assumption for the Company’s domestic Pension Benefits plans was 8.75% in 2005, 2004 and

2003. The long-term return on asset assumption for the Company’s Other Benefits plans was 8.75% in 2005 and 7.75% in 2004 and 2003. To develop the expected long-term rate of return on asset assumptions, the Company considered the current level of expected returns on risk free investments, the historical level of the risk premium associated with the other asset classes in which the Company has invested domestic Pension Benefits and Other Benefits plan assets, and the expectations for future returns of each asset class. Since the Company’s investment policy is to employ active management strategies in all asset classes, the potential exists to outperform the broader markets; therefore, the expected returns were adjusted upward. The expected return for each asset class was then weighted based on the target asset allocation to develop the long-term return on asset assumptions.

The long-term return on asset assumptions for foreign Pension Benefits plans are based on the asset allocations and the economic environment prevailing in the locations where the Pension Benefits plans reside. Foreign pension assets do not make up a significant portion of the total assets for all of the Company’s Pension Benefits plans.

The tables below detail assets by category for the Company’s domestic and foreign Pension Benefits and Other Benefits plans. These assets consist primarily of publicly-traded equity securities and publicly-traded fixed income securities.

The tables below provide a reconciliation of benefit obligations, plan assets, funded status, and related actuarial assumptions of the Company’s domestic and foreign Pension Benefits and Other Benefits plans.

The fair value of plan assets for the Company’s domestic and foreign Pension Benefits plans was $12,017 million and $434 million, respectively at December 31, 2005 and $10,873 million and $400 million, respectively, at December 31, 2004.

The table above reconciles the difference between the benefit obligation and the fair value of plan assets to the amounts recorded on the Company’s balance sheet due to certain items that are amortized over future periods rather than recognized in the current period.

The Company’s foreign Pension Benefits plan assumptions have been included in the table above.

The tables below outline the components of net periodic benefit cost and related actuarial assumptions of the Company’s domestic and foreign Pension Benefits and Other Benefits plans.

Net periodic benefit cost also includes expense from foreign Pension Benefits plans of $31 million in 2005, $32 million in 2004, and $20 million in 2003.

The effect of a 1% increase or (decrease) in the assumed health care trend rate for each future year for the aggregate of service cost and interest cost is $3 million or $(3) million, respectively, and for the accumulated postretirement benefit obligation is $35 million or $(45) million, respectively.

The projected benefit obligation and fair value of plan assets for Pension Benefits plans with projected benefit obligations in excess of plan assets were $15,154 million and $10,972 million, respectively, at December 31, 2005, and $13,763 million and $9,900 million, respectively, at December 31, 2004.

The accumulated benefit obligation and fair value of plan assets for Pension Benefits plans with accumulated benefit obligations in excess of plan assets were $13,455 million and $10,944 million, respectively, at December 31, 2005 and $12,198 million and $9,878 million, respectively, at December 31, 2004. The accumulated benefit obligation for all Pension Benefits plans was $14,638 million and $13,314 million at December 31, 2005 and 2004, respectively.

The Company expects total contributions (required and discretionary) to the Pension Benefits and Other Benefits plans to be approximately $640 million and $75 million, respectively, in 2006.

The table below reflects the total Pension Benefits expected to be paid from the plans or from the Company’s assets, including both the Company’s share of the benefit cost and the participants’ share of the cost, which is funded by participant contributions. Other Benefits payments reflect the Company’s portion only.

The Company also maintains additional contractual pension benefits agreements for its top executive officers. The liability was $25 million and $22 million at December 31, 2005 and 2004, respectively.

On December 8, 2003, Medicare reform legislation (the “Legislation”) was enacted, providing a Medicare prescription drug benefit beginning in 2006 and federal subsidies to employers who provide drug coverage to retirees. The Company’s net periodic benefit cost was reduced by $3 million in 2004 to reflect the impact of the Legislation in accordance with FASB Staff Position No. FAS 106-2, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003. The reduction in the accumulated postretirement benefit obligation as a result of the Legislation was $45 million.

Effective July 1, 2004, the Company amended its Other Benefits plans to coordinate the Company’s retiree prescription drug coverage with the Legislation beginning in 2006. The amendment eliminated the plans’ eligibility for the federal subsidies provided under the Legislation, as described above. The effect of the amendment on the Company’s net periodic benefit cost was a $15 million decrease in 2004. The reduction in the accumulated postretirement benefit obligation as a result of the plan amendment was $125 million.

The Company maintains an employee stock ownership plan (ESOP) which includes the Company’s 401(k) plan (defined contribution plan), under which covered employees are allowed to contribute up to a specific percentage of their pay. The Company matches the employee’s contribution, up to a maximum of generally between 3 and 4% of the employee’s pay (Company Match). Prior to January 1, 2005, the Company Match was made through a contribution to the Company stock fund. Effective January 1, 2005, the Company Match was invested in the same way as employee contributions. Total expense for the Company Match was $197 million, $180 million, and $159 million in 2005, 2004, and 2003, respectively.

Prior to January 1, 2005, the Company made an annual contribution to the Company stock fund of approximately one-half of one percent of salaries and wages, subject to certain limitations, of most U.S. salaried and hourly employees (Company Contributions). Effective January 1, 2005, the Company discontinued the annual contribution to the Company stock fund. The contribution for 2004 was made in March 2005. Total expense for the Company Contributions was $27 million, $25 million, and $25 million and the number of shares allocated to participant accounts was 706,000, 813,000, and 884,000 in 2005, 2004, and 2003, respectively.

The Company purchased shares on the open market for the Company Match and Company Contributions in 2005. The Company funded a portion of the Company Match and Company Contributions in 2004 and 2003 through the issuance of common stock.

At December 31, 2005, there was a total of $9.4 billion invested in the Company’s defined contribution plan. At December 31, 2005, there was a total of $1.8 billion invested in the Company stock fund consisting of $472 million of Company Match which must remain invested in the Company stock fund for five years from the year in which the contribution was made or the year in which the employee reaches age 55, whichever is earlier; $304 million of Company Contributions which must remain invested in the Company stock fund until the employee reaches age 55 and completes 10 years of service; and $1,023 million over which there are no restrictions.

Segment net sales and operating income generally include intersegment sales and profit recorded at cost plus a specified fee, which may differ from what the selling entity would be able to obtain on external sales. Corporate and Eliminations includes certain Company-wide accruals and intersegment sales and profit eliminations. In 2005, certain programs within Intelligence and Information Systems, Network Centric Systems, and Technical Services were realigned within those same segments. Information for all prior periods presented was reclassified to reflect these changes.

Intersegment sales in 2005, 2004, and 2003, respectively, were $101 million, $133 million, and $140 million for Integrated Defense Systems, $37 million, $41 million, and $54 million for Intelligence and Information Systems, $25 million, $16 million, and $7 million for Missile Systems, $396 million, $444 million, and $316 million for Network Centric Systems, $477 million, $428 million, and $402 million for Space and Airborne Systems, $534 million, $527 million, and $527 million for Technical Services. Aircraft net sales did not include intersegment aircraft, parts, and service sales to Flight Options of $108 million and $151 million in 2005 and 2004, respectively.

Intersegment operating income in 2005, 2004, and 2003, respectively, were $7 million, $10 million, and $11 million for Integrated Defense Systems, $4 million, $3 million, and $4 million for Intelligence and Information Systems, $2 million, $1 million, and $1 million for Missile Systems, $35 million, $36 million, and $25 million for Network Centric Systems, $46 million, $41 million, and $39 million for Space and Airborne Systems, $51 million, $47 million, and $53 million for Technical Services. Aircraft operating income does not include profit on intersegment aircraft sales to Flight Options until the underlying aircraft has been sold by Flight Options.

The following table reconciles operating income to income from continuing operations before taxes:

Corporate free cash flow includes the difference between amounts charged to the segments for interest and taxes on an intercompany basis and the amounts actually paid by the Company. Also included in Corporate free cash flow in 2004 was a $210 million payment in connection with the settlement of a securities class action lawsuit described in Note L, Commitments and Contingencies.

The following table reconciles total segment free cash flow to net cash provided by operating activities from continuing operations:

The country of destination was used to attribute sales to either United States or Outside United States (excluding foreign military sales). Sales to major customers in 2005, 2004, and 2003 were: U.S. government, including foreign military sales, $16,133 million, $14,973 million, and $13,436 million, respectively, including U.S. Department of Defense, $14,692 million, $13,616 million, and $11,766 million, respectively.

Note: Earnings per share are computed independently for each of the quarters presented, therefore, the sum of the quarterly earnings per share may not equal the total computed for the year.

At December 31, 2005, the Company recorded forward exchange contracts designated as cash flow hedges at their fair value. Unrealized gains of $51 million were included in noncurrent assets and unrealized losses of $45 million were included in current liabilities. The offset was included in other comprehensive income, net of tax, of which approximately $3 million of net unrealized losses are expected to be reclassified to earnings over the next twelve months as the underlying transactions mature. Gains and losses resulting from these cash flow hedges offset the foreign exchange gains and losses on the underlying assets or liabilities being hedged. The maturity dates of the forward exchange contracts outstanding at December 31, 2005 extend through 2013. Certain immaterial contracts were not designated as effective hedges and therefore were included in other expense. The amount charged to other expense related to these contracts was less than $1 million in 2005, 2004, and 2003.

The Company enters into interest rate swaps, as described in Note H, Notes Payable and Long-Term Debt. These interest rate swaps were designated as fair value hedges. There was no hedge ineffectiveness in 2005, 2004, or 2003.

Major currencies and the approximate amounts associated with foreign exchange contracts consisted of the following at December 31:

Buy amounts represent the U.S. dollar equivalent of commitments to purchase foreign currencies and sell amounts represent the U.S. dollar equivalent of commitments to sell foreign currencies. Foreign exchange contracts that do not involve U.S. dollars have been converted to U.S. dollars for disclosure purposes.

Foreign currency forward contracts, used to fix the dollar value of specific commitments and payments to international vendors and the value of foreign currency denominated receipts, have maturities at various dates through 2013 as follows: $1,093 million in 2006, $407 million in 2007, $168 million in 2008, $21 million in 2009, and $29 million thereafter.

In 2005, the Company sold its investment in Indra ATM S.L., a Spanish joint venture for $59 million and recorded a gain of $45 million.

In 2003, the Company sold the remaining interest in its former aviation support business (Raytheon Aerospace) for $97 million and recorded a gain of $82 million. In 2004, the Company resolved a dispute related to the sale and received an additional $4 million. The Company had sold a majority interest in Raytheon Aerospace in 2001 and retained a 26% ownership interest that was recorded at zero because the new entity was highly-leveraged.
