Accounting Policies [Abstract]

Consolidation and Classification [Policy Text Block]

Consolidation and Classification—The consolidated financial statements include the accounts of Raytheon Company, and all wholly-owned, majority-owned and otherwise controlled domestic and foreign subsidiaries. All intercompany transactions have been eliminated. For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year. In addition, we reclassified certain amounts to conform to our current period presentation. As used in these notes, the terms “we,” “us,” “our,” “Raytheon” and the “Company” mean Raytheon Company and its subsidiaries, unless the context indicates another meaning.

Effective January 1, 2019, we adopted the requirements of Accounting Standards Update (ASU) 2016-02, Leases (Topic 842) using the modified retrospective approach as discussed below in Accounting Standards. We reclassified certain balance sheet amounts to conform to our current period presentation.

Use of Estimates [Policy Text Block]

Use of Estimates—Our consolidated financial statements are based on the application of U.S. Generally Accepted Accounting Principles (GAAP), which require us to make estimates and assumptions about future events that affect the amounts reported in our consolidated 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 our consolidated financial statements.

Revenue Recognition [Policy Text Block]

Revenue Recognition—The vast majority of our revenues are from long-term contracts associated with the design, development, manufacture or modification of complex aerospace or defense equipment or related services. These contracts primarily are with the U.S. government (including foreign military sales contracted through the U.S. government). Our contracts with the U.S. government typically are subject to the Federal Acquisition Regulation (FAR) and are priced based on estimated or actual costs of producing goods or providing services. The FAR provides guidance on the types of costs that are allowable in establishing prices for goods and services provided under U.S. government contracts. The pricing for non-U.S. government contracts is based on the specific negotiations with each customer.

Under the typical payment terms of our U.S. government fixed-price contracts, the customer pays us either performance-based payments (PBPs) or progress payments. PBPs are interim payments equal to a negotiated percentage of the contract price based on quantifiable measures of performance or on the achievement of specified events or milestones. Progress payments are interim payments up to 80% of costs incurred as the work progresses. Because the customer retains a portion of the contract price until completion of the contract, our U.S. government fixed-price contracts generally result in revenue recognized in excess of billings which we present as contract assets on the balance sheet. Amounts billed and due from our customers are classified as receivables on the balance sheet. The portion of the payments retained by the customer until final contract settlement is not considered a significant financing component because the intent is to protect the customer. For our U.S. government cost-type contracts, the customer generally pays us for our actual costs incurred within a short period of time. For non-U.S. government contracts, we typically receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. We recognize a liability for these advance payments in excess of revenue recognized and present it as contract liabilities on the balance sheet. The advance payment typically is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect us from the other party failing to adequately complete some or all of its obligations under the contract.

To determine the proper revenue recognition method for contracts for complex aerospace or defense equipment or related services, we evaluate whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate the combined or single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. For most of our contracts, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability (even if that single project results in the delivery of multiple units). Hence, the entire contract is accounted for as one performance obligation. Less commonly, however, we may promise to provide distinct goods or services within a contract, for example when a contract covers multiple phases of the product lifecycle (e.g., development, production, maintenance and support), in which case we separate the contract into more than one performance obligation. If a contract is

separated into more than one performance obligation, we allocate the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. We infrequently sell standard products with observable standalone sales. In cases where we do, the observable standalone sales are used to determine the standalone selling price. More frequently, we sell a customized customer specific solution, and in these cases we typically use the expected cost plus a margin approach to estimate the standalone selling price of each performance obligation.

We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. For certain contracts that meet the foregoing requirements, primarily international direct commercial sale contracts, we are required to obtain certain regulatory approvals. In these cases, we recognize revenue based on the likelihood of obtaining regulatory approvals based upon all known facts and circumstances.

We generally recognize revenue over time as we perform on our contractual performance obligations because of continuous transfer of control to the customer. For U.S. government contracts, this continuous transfer of control to the customer is supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. Similarly, for non-U.S. government contracts, the customer typically controls the work in process as evidenced either by contractual termination clauses or by our rights to payment for work performed to date plus a reasonable profit to deliver products or services that do not have an alternative use to the Company.

Because of control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We generally use the cost-to-cost measure of progress for our contracts because it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Costs to fulfill include labor, materials and subcontractors’ costs, other direct costs and an allocation of indirect costs including pension and any other postretirement benefit (PRB) expense under U.S. government Cost Accounting Standards (CAS).

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion (the process described below in more detail) is complex, subject to many variables and requires significant judgment by management on a contract by contract basis. It is common for our long-term contracts to contain award fees, incentive fees, or other provisions that can either increase or decrease the transaction price. These variable amounts generally are awarded upon achievement of certain performance metrics, program milestones or cost targets and can be based upon customer discretion. We estimate variable consideration at the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

Contracts are often modified to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

We have a companywide standard and disciplined quarterly Estimate at Completion (EAC) process in which management reviews the progress and execution of our performance obligations. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program

schedule, identified risks and opportunities and the related changes in estimates of revenues and costs. The risks and opportunities include management’s judgment about the ability and cost to achieve the schedule (e.g., the number and type of milestone events), technical requirements (e.g., a newly-developed product versus a mature product) and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, the length of time to complete the performance obligation (e.g., to estimate increases in wages and prices for materials and related support cost allocations), execution by our subcontractors, the availability and timing of funding from our customer, and overhead cost rates, among other variables. These estimates also include the estimated cost of satisfying our industrial cooperation agreements, sometimes in the form of either offset obligations or in-country industrial participation (ICIP) agreements, required under certain contracts. These obligations may or may not be distinct depending on their nature.

Based on this analysis, any quarterly adjustments to net sales, cost of sales and the related impact to operating income are recognized as necessary in the period they become known. These adjustments may result from positive program performance, and may result in an increase in operating income during the performance of individual performance obligations, if we determine we will be successful in mitigating risks surrounding the technical, schedule and cost aspects of those performance obligations or realizing related opportunities. Likewise, these adjustments may result in a decrease in operating income if we determine we will not be successful in mitigating these risks or realizing related opportunities. Changes in estimates of net sales, cost of sales and the related impact to operating income are recognized quarterly on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. A significant change in one or more of these estimates could affect the profitability of one or more of our performance obligations. When estimates of total costs to be incurred exceed total estimates of revenue to be earned on a performance obligation related to complex aerospace or defense equipment or related services, or product maintenance or separately priced extended warranty, a provision for the entire loss on the performance obligation is recognized in the period the loss is identified.

Net EAC adjustments had the following impact on our operating results:

(In millions, except per share amounts)	2019(1)		2018(1)		2017
Operating income	$	520	$	492	$	442
Income from continuing operations attributable to Raytheon Company	411		389		287
Diluted EPS from continuing operations attributable to Raytheon Company	$	1.47	$	1.36	$	0.98

(1) Amounts reflect a U.S. statutory tax rate of 21%, which became effective in 2018 with the adoption of the Tax Cuts and Jobs Act of 2017 (2017 Act).

In addition, net revenue recognized from our performance obligations satisfied in previous periods was $709 million, $636 million and $520 million in 2019, 2018 and 2017, respectively. This primarily relates to EAC adjustments that impacted revenue.

We also sell security software through our Forcepoint business segment. For the majority of these arrangements, we recognize revenue over the term of the agreement because the software requires continuous updates to provide the intended security functionality. To a lesser extent in all of our business segments, we enter into other types of contracts including service arrangements and non-subscription software and licensing agreements. We recognize revenue for these arrangements over time or at a point in time depending on our evaluation of when the customer obtains control of the promised goods or services. For software arrangements that include multiple performance obligations, including hardware, perpetual software licenses, subscriptions, term licenses and maintenance and/or services, we allocate revenue to each performance obligation based on estimates of the price that we would charge the customer for each promised product or service if it were sold on a standalone basis.

Certain events have caused increased attention on U.S. defense sales to the Kingdom of Saudi Arabia (KSA). KSA represents less than 5% of our sales and $2.9 billion of our remaining performance obligations at December 31, 2019. Although we currently do not expect to be prevented from doing business in KSA, if government action impairs our ability to fulfill our contractual obligations or otherwise to continue to do business in KSA, it would have a material adverse effect on our financial results.

Research and Development Expenses [Policy Text Block]

Research and Development Expenses—Research and development expenses are included in general and administrative expenses in our consolidated statements of operations and have primarily been for product development for the U.S. government. Expenditures for Company-sponsored research and development projects are expensed as incurred, and were $732 million, $841 million and $700 million in 2019, 2018 and 2017, respectively. Customer-sponsored research and development projects performed under contracts are accounted for as contract costs as the work is performed and included in receivables, net or contract assets in our consolidated balance sheets, depending on whether costs have been billed or not.

Federal, Foreign and State Income Taxes [Policy Text Block]

Federal, Foreign and State 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 record provisions for income taxes at applicable foreign tax rates in a similar manner. Such provisions differ from the amounts currently payable because certain items of income and expense are recognized in different time periods for financial reporting purposes than for income tax purposes. The Company provides for a U.S. tax liability on outside basis differences in our foreign subsidiaries related to earnings which have been previously taxed in the U.S. and undistributed earnings generated after December 31, 2017. This U.S. deferred tax liability generally relates to foreign currency movement. The Company also records foreign withholding taxes applicable to distributions of foreign earnings. The Company continues to assert indefinite reinvestment on outside basis differences related to all other items, such as acquisition accounting adjustments prior to January 1, 2018. With the exception of Forcepoint, payments made for state income taxes are 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 in which the tax is payable. Accordingly, the state income tax provision (benefit) is allocated to contracts when it is paid (recovered) or otherwise agreed as allocable with the U.S. government. Payments made for state income taxes related to Forcepoint are included in federal and foreign income tax expense.

Other (Income) Expense, Net [Policy Text Block]

Other (Income) Expense, Net—Other (income) expense, net, consists primarily of gains and losses from our investments held in trusts used to fund certain of our non-qualified deferred compensation and employee benefit plans, gains and losses on the early repurchase of long-term debt and certain financing fees. Periodically we enter into equity method or other investments that are not related to our core operations, including investments in early stage technology companies. We record the income or loss from these investments as a component of other (income) expense, net. We record losses beyond the carrying amount of the investment only when we guarantee obligations of the investee or commit to provide the investee further financial support.

Cash and Cash Equivalents [Policy Text Block]

Cash and Cash Equivalents—Cash and cash equivalents consist of cash and highly liquid investments with original maturities of 90 days or less at the date of purchase. The estimated fair value of cash and cash equivalents approximates the carrying value due to their short maturities. Cash and cash equivalents excludes $6 million and $16 million of restricted cash at December 31, 2019 and December 31, 2018, respectively, which for purposes of our consolidated statements of cash flows, is included in cash, cash equivalents and restricted cash.

Short-term Investments [Policy Text Block]

Short-term Investments—We may invest in marketable securities in accordance with our short-term investment policy and cash management strategy. Marketable securities are classified as available-for-sale and are recorded at fair value as short-term investments in our consolidated balance sheets. These investments are deemed Level 2 assets under the fair value hierarchy as their fair value is determined under a market approach using valuation models that utilize observable inputs, including maturity date, issue date, settlements date and current rates. At December 31, 2019 and 2018, we had no short-term investments as all short-term investments outstanding at December 31, 2017 matured in the first quarter of 2018. We did not have any sales of short-term investments in 2019 or 2018. For purposes of computing realized gains and losses on available-for-sale securities, we determine cost on a specific identification basis.

Receivables, Net [Policy Text Block]

Receivables, Net—Receivables, net, include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. We maintain an allowance for doubtful accounts to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables and collateral to the extent applicable.

Receivables, net, consisted of the following at December 31: 

(In millions)	2019			2018
U.S. government contracts (including foreign military sales)	$	777		$	1,121
Other customers	594			539
Allowance for doubtful accounts	(7		)	(12		)
Total receivables, net	$	1,364		$	1,648

Contract Assets [Policy Text Block]

Contract Assets—Contract assets include unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to payment is not just subject to the passage of time. Amounts may not exceed their net realizable value. Contract assets are generally classified as current.

Inventories [Policy Text Block]

Inventories—Inventories are stated at the lower of its cost (first-in, first-out or average cost) or net realizable value. An impairment 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.

Inventories consisted of the following at December 31: 

(In millions)	2019		2018
Materials and purchased parts	$	78	$	75
Work in process	574		662
Finished goods	19		21
Total	$	671	$	758

Precontract costs are costs incurred to fulfill a contract prior to contract award. Precontract costs, including general and administrative expenses that are specifically chargeable to the customer, are deferred in inventories if we determine that the costs are probable of recovery under a specific anticipated contract. All other precontract costs, including start-up costs, are expensed as incurred. Costs that are deferred are recognized as contract costs upon the receipt of the anticipated contract. We included deferred precontract costs of $182 million and $163 million in inventories as work in process at December 31, 2019 and December 31, 2018, respectively.

Deferred Commissions [Policy Text Block]

Deferred Commissions—Our incremental direct costs of obtaining a contract, which consist of sales commissions primarily for our security software sales at Forcepoint, are deferred and amortized over the period of contract performance or a longer period, generally the estimated life of the customer relationship, if renewals are expected and the renewal commission is not commensurate with the initial commission. We classify deferred commissions as current or noncurrent based on the timing of when we expect to recognize the expense. The current and noncurrent portions of deferred commissions are included in prepaid expenses and other current assets, and other assets, net, respectively, in our consolidated balance sheets. At both December 31, 2019 and December 31, 2018, we had deferred commissions of $55 million. Amortization expense related to deferred commissions was $26 million, $45 million and $28 million in 2019, 2018 and 2017, respectively.

Property, Plant and Equipment, Net [Policy Text Block]

Property, Plant and Equipment, Net—Property, plant and equipment, net, are stated at cost less accumulated depreciation. Major improvements are capitalized while expenditures for maintenance, repairs and minor improvements are expensed. We include gains and losses on the sales of plant and equipment that are allocable to our contracts in overhead as we generally can recover these costs through the pricing of products and services to the U.S. government. For all other sales or asset retirements, the assets and related accumulated depreciation and amortization are eliminated from the accounts, and any resulting gain or loss is reflected in operating income.

Provisions for depreciation generally are computed using a combination of accelerated and straight-line methods and are based on estimated useful lives as follows: 

	Years
Machinery and equipment	3–10
Buildings	20–45

Leasehold improvements are amortized over the lesser of the remaining lease term or the estimated useful life of the improvement.

Leases [Policy Text Block]

Leases—We determine if an arrangement is a lease or contains an embedded lease at inception. For lease agreements with both lease and nonlease components (e.g., common-area maintenance costs), we account for the nonlease components separately. Consideration is allocated to the lease and nonlease components based on the estimated standalone prices.

All of our existing leases are operating leases. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future lease payments over the lease term at the commencement date. The current portion of operating lease liabilities is included in other current liabilities in our consolidated balance sheets. For the majority of our leases, the discount rate used to determine the present value of the lease payments is our incremental borrowing rate as of the lease commencement date, as the implicit rate is not readily determinable. The operating lease right-of-use assets also includes any initial direct costs and any lease payments made at or before the commencement date, and is reduced for any unrestricted incentives received at or before the commencement date.

Some of our leases include options to extend or terminate the lease. We include these options in the recognition of our right-of-use assets and lease liabilities when it is reasonably certain that we will exercise the option. Very few of our leases include variable lease-related payments, such as escalation clauses based on consumer price index (CPI) rates, or residual guarantees. Variable payments that are based on an index or a rate are included in the recognition of our right-of-use assets and lease liabilities using the index or rate at lease commencement; however, changes to these lease payments due to rate or index updates are recorded as lease expense in the period incurred. Amounts probable of payment under residual guarantees are also included in the recognition of our right-of-use assets and lease liabilities.

Impairment of Goodwill and Long-lived Assets [Policy Text Block]

Impairment of Goodwill and Long-lived Assets—We evaluate our goodwill for impairment annually or whenever events or circumstances indicate that the carrying value of goodwill may not be recoverable. We perform our annual impairment test as of the first day of the fourth quarter utilizing a two-step methodology that requires us to first identify potential goodwill impairment and then measure the amount of the related goodwill impairment loss, if any. We have identified our operating segments as reporting units under the impairment test assessment criteria outlined in U.S. GAAP. In performing our annual impairment test in the fourth quarters of 2019, 2018 and 2017 we did not identify any goodwill impairment.

We determine whether long-lived assets are to be held for use or disposal. Upon indication of possible impairment of long-lived assets held for use, we evaluate the recoverability of such 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 group, the asset group is adjusted to its estimated fair value. In order for long-lived assets to be considered held for disposal, we must have committed to a plan to dispose of the assets. Once deemed held for disposal, the assets are stated at the lower of the carrying amount or fair value.

Computer Software, Net [Policy Text Block]

Computer Software, Net—Internal use computer software, net, included in other assets, net, which consists primarily of our enterprisewide software solutions, is stated at cost less accumulated amortization and is amortized using the straight-line method over its estimated useful life, generally 10 years. Computer software development costs related to software products developed for external use are capitalized, when significant, after establishment of technological feasibility and marketability. There have been no such costs capitalized to date as the costs incurred during the period between technological feasibility to general release have not been significant.

Contract Liabilities [Policy Text Block]

Contract Liabilities—Our contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue. We may also receive up-front payments related to software license sales primarily for Forcepoint, which

in most cases we recognize ratably over the license term. Our contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. We classify advance payments and billings in excess of revenue recognized as current, and deferred revenue as current or noncurrent based on the timing of when we expect to recognize revenue. The noncurrent portion of deferred revenue is included in accrued retiree benefits and other long-term liabilities in our consolidated balance sheets.

In order to determine revenue recognized in the period from contract liabilities, we first allocate revenue to the individual contract liability balance outstanding at the beginning of the period until the revenue exceeds that balance. If additional advances are received on those contracts in subsequent periods, we assume all revenue recognized in the reporting period first applies to the beginning contract liability as opposed to a portion applying to the new advances for the period.

Redeemable Noncontrolling Interests [Policy Text Block]

Redeemable Noncontrolling Interests—Redeemable noncontrolling interest is recognized at the greater of the estimated redemption value as of the balance sheet date or the initial value adjusted for the noncontrolling interest holder’s share of the cumulative impact of net income (loss), other changes in accumulated other comprehensive income (loss) and additional contributions. Adjustments to the redemption value over the period from the date of acquisition to the redemption date are immediately recorded to retained earnings. We reflect the redemption value adjustments in the earnings per share (EPS) calculation if redemption value is in excess of the fair value of noncontrolling interest which resulted in a $0.01 favorable impact to both basic and diluted EPS in 2018. There was no impact to basic or diluted EPS in 2019 or 2017 related to the redemption value adjustments.

Other Comprehensive Income (Loss) [Policy Text Block]

Other Comprehensive Income (Loss)—Other comprehensive income (loss) includes gains and losses associated with pension and PRB plans, foreign exchange translation adjustments, gains and losses on derivative instruments qualified as cash flow hedges included in the assessment of effectiveness, and unrealized gains (losses) on available-for-sale investments. The computation of other comprehensive income (loss) and its components are presented in the consolidated statements of comprehensive income.

A rollforward of accumulated other comprehensive income (loss) was as follows:

	Pension and PRB plans, net(1)			Foreign exchange translation			Cash flow hedges(2)			Unrealized gains (losses) on investments and other, net(3)			Total
(In millions)
Balance at December 31, 2016	$	(7,234	)	$	(175	)	$	—		$	(2	)	$	(7,411	)

Balance at December 31, 2019	$	(9,132	)	$	(124	)	$	1		$	(5	)	$	(9,260	)

(1) Pension and PRB plans, net, is shown net of cumulative tax benefits of $2,428 million and $2,255 million at December 31, 2019 and December 31, 2018, respectively.

(2) Cash flow hedges are shown net of cumulative tax of zero and tax benefits of $1 million at December 31, 2019 and December 31, 2018, respectively.

(3) Unrealized gains (losses) on investments and other, net, are shown net of cumulative tax expense of $1 million at both December 31, 2019 and December 31, 2018.

In the first quarter of 2018, we reclassified the stranded tax effects related to the enactment of the 2017 Act from accumulated other comprehensive loss (AOCL) to retained earnings in accordance with ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. These stranded tax effects related to the deferred tax amounts at December 31, 2017 recorded through other comprehensive income prior to the enactment date using the prior 35% statutory tax rate that remained in other comprehensive income despite the fact that the related deferred tax assets and liabilities were remeasured to reflect the newly enacted tax rate of 21%. See Accounting Standards, below, for additional details.

Other material amounts reclassified out of AOCL related to the amortization of net actuarial loss associated with our pension plans were $1,050 million, $1,351 million and $1,177 million before tax in 2019, 2018 and 2017, respectively. This component of AOCL is included in the calculation of net periodic pension expense (income). See “Note 14: Pension and Other Employee Benefits” for additional details.

We expect $3 million net of tax of net unrealized gains on our cash flow hedges at December 31, 2019 to be reclassified into earnings at then-current values over the next 12 months as the underlying hedged transactions occur.

Translation of Foreign Currencies [Policy Text Block]

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 AOCL in equity. Prior to the enactment of the 2017 Act, deferred taxes were not recognized for translation-related temporary differences of foreign subsidiaries as their undistributed earnings were considered to be indefinitely reinvested. After the enactment of the 2017 Act, we no longer assert indefinite reinvestment on our foreign subsidiaries outside basis differences generated after December 31, 2017. Unrealized foreign currency gains and losses associated with the subsidiary’s net assets, including unremitted earnings, represent translation gains and losses that are reported as part of other comprehensive income (loss). Therefore, the deferred tax effect of the translation gains and losses are also recorded through other comprehensive income (loss) after December 31, 2017. At December 31, 2019, we had a cumulative translation loss on the unremitted earnings, and therefore, have not recorded a deferred tax asset as it is not likely that the asset will be realized in the future. Income and expenses in foreign currencies are translated at the average exchange rate during the period.

Foreign exchange transaction gains and losses in 2019, 2018 and 2017 were not material.

Treasury Stock [Policy Text Block]

Treasury Stock—Repurchased shares are retired immediately upon repurchase. We account for treasury stock under the cost method. Upon retirement the excess over par value is charged against additional paid-in capital until reduced to zero, with the remainder recorded as a reduction to retained earnings.

Pension and Other Postretirement Benefits (PRB) Costs [Policy Text Block]

Pension and Other Postretirement Benefits (PRB) Costs—We have pension plans covering the majority of our employees hired before January 1, 2007, including certain employees in foreign countries. We calculate our pension costs as required under U.S. GAAP, and the calculations and assumptions utilized require judgment. U.S. GAAP outlines the methodology used to determine pension expense or income for financial reporting purposes. Pension and PRB expense is split between operating income and non-operating income, where only the service cost component is included in operating income and the non-service components are included in retirement benefits non-service expense. For purposes of determining retirement benefits non-service expense under U.S. GAAP, a calculated “market-related value” of our plan assets is used to develop the amount of deferred asset gains or losses to be amortized. The market-related value of assets is determined using actual asset gains or losses over a three-year period. Under U.S. GAAP, a “corridor” approach may be elected and applied in the recognition of asset and liability gains or losses which limits expense recognition to the net outstanding gains and losses in excess of the greater of 10% of the projected benefit obligation (PBO) or the calculated “market-related value” of assets. We do not use a “corridor” approach in the calculation of Financial Accounting Standards (FAS) pension expense.

We recognize the funded status of a postretirement benefit plan (defined benefit pension and other benefits) as an asset or liability in our consolidated balance sheets. Funded status represents the difference between the PBO of the plan and the market value of the plan’s assets. Previously unrecognized deferred amounts such as demographic or asset gains or losses and the impact of historical plan changes are included in AOCL. Changes in these amounts in future years will be reflected through AOCL and amortized in future pension expense generally over the estimated average remaining employee service period.

Derivative Financial Instruments [Policy Text Block]

Derivative Financial Instruments—We enter into foreign currency forward contracts with commercial banks to fix the foreign currency exchange rates on specific commitments, payments and receipts denominated in foreign currencies. Our foreign currency forward contracts are transaction driven and relate directly to a particular asset, liability or transaction for which commitments are in place. We execute these instruments with financial institutions that we judge to be credit-worthy. The majority of our foreign currency forward contracts are denominated in currencies of major industrial countries. We do not hold or issue derivative financial instruments for trading or speculative purposes.

We designate most foreign currency forward contracts as cash flow hedges of forecasted purchases and sales denominated in foreign currencies. For foreign currency forward contracts designated and qualified for cash flow hedge accounting, we record the effective portion of the gain or loss on the derivative in AOCL, net of tax, and reclassify it into earnings in the same period or periods during which the hedged revenue or cost of sales transaction affects earnings. Realized gains and losses resulting from these cash flow hedges offset the foreign exchange gains and losses on the underlying transactions being hedged. We classify the cash flows from these instruments in the same category as the cash flows from the hedged items. To a lesser extent, we have gains and losses on derivatives not designated for hedge accounting or representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness, which are recognized currently in net sales or cost of sales.

The aggregate notional amount of the outstanding foreign currency forward contracts was $1,487 million and $1,772 million at December 31, 2019 and December 31, 2018, respectively. The net notional exposure of these contracts was $746 million and $840 million at December 31, 2019 and December 31, 2018, respectively. The foreign currency forward contracts at December 31, 2019 have maturities at various dates through 2030 as follows: $922 million in 2020; $315 million in 2021; $122 million in 2022; and $128 million thereafter.

We recognize all derivative financial instruments as either assets or liabilities at fair value in our consolidated balance sheets. The fair value of asset derivatives included in other assets, net and liability derivatives included in other current liabilities in our consolidated balance sheets related to foreign currency forward contracts were as follows:

(In millions)	2019		2018
Asset derivatives related to foreign currency forward contracts	$	29	$	26
Liability derivatives related to foreign currency forward contracts	15		34

The fair value of these derivatives is Level 2 in the fair value hierarchy because they are determined based on a market approach utilizing externally quoted foreign currency forward rates for similar contracts. Our foreign currency forward contracts contain offset or netting provisions to mitigate credit risk in the event of counterparty default, including payment default and cross default. We measure and record the impact of counterparty credit risk into our valuation and at December 31, 2019 and December 31, 2018, the fair value of our counterparty default exposure was less than $1 million and was spread across numerous highly rated counterparties.

We may also enter into pay-variable, receive-fixed interest rate swaps to manage interest rate risk associated with our fixed-rate financing obligations. We account for our interest rate swaps as fair value hedges of a portion of our fixed-rate financing obligations, and accordingly record gains and losses from changes in the fair value of these swaps in interest expense, along with the offsetting gains and losses on the fair value adjustment of the hedged portion of our fixed-rate financing obligations. We also record in interest expense the net amount paid or received under the swap for the period and the amortization of gain or loss from the early termination of interest rate swaps. There were no interest rate swaps outstanding at December 31, 2019 or December 31, 2018.

We may also enter into and designate treasury rate lock contracts as cash flow hedges to reduce variability in cash flows due to changes in interest payments attributable to increases or decreases in the benchmark interest rate during the period leading up to the probable issuance of long-term debt. Cash flows associated with these instruments are presented in the same category as the cash flows from the hedged item. In May 2019, prior to entering into an Agreement and Plan of Merger (the Merger Agreement) with United Technologies Corporation (UTC), we entered into treasury rate lock contracts with a notional amount of $375 million. These treasury rate lock contracts were designated as cash flow hedges and were included in the assessment of effectiveness. However, in the fourth quarter of 2019 a decision was made to not issue the debt due to merger-related considerations, and these treasury rate locks were settled without the issuance of debt. We recognized the $17 million loss

included in accumulated other comprehensive income at the time of settlement in other (income) expense, net. There were no treasury rate lock contracts outstanding at December 31, 2019 or December 31, 2018.

Fair Values [Policy Text Block]

Fair Values—Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required:

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Observable inputs, other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or that we corroborate with observable market data for substantially the full term of the related assets or liabilities.

Level 3: Unobservable inputs supported by little or no market activity that are significant to the fair value of the assets or liabilities.

Assets and liabilities measured at fair value on a recurring basis consisted of marketable securities held in trusts and foreign currency forward contracts as of December 31, 2019 and 2018. Fair value information for those assets and liabilities, including their classification in the fair value hierarchy, is included in “Note 14: Pension and Other Employee Benefits” (for marketable securities held in trusts) and Derivative Financial Instruments, above (for foreign currency forward contracts). Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. We did not have any significant nonfinancial assets or nonfinancial liabilities that would be recognized or disclosed at fair value on a recurring basis as of December 31, 2019 and 2018. We did not have any material amounts of Level 3 assets or liabilities at December 31, 2019 and 2018.

Earnings per Share (EPS) [Policy Text Block]

Earnings per Share (EPS)—We compute basic EPS attributable to Raytheon Company common stockholders by dividing income from continuing operations attributable to Raytheon Company common stockholders, income (loss) from discontinued operations attributable to Raytheon Company common stockholders, and net income attributable to Raytheon Company, by our weighted-average common shares outstanding, including participating securities outstanding, as described below, during the period. Diluted EPS reflects the potential dilution beyond shares for basic EPS that could occur if securities or other contracts to issue common stock were exercised, converted into common stock, or resulted in the issuance of common stock that would have shared in our earnings. We compute basic and diluted EPS using actual income from continuing operations attributable to Raytheon Company common stockholders, income (loss) from discontinued operations attributable to Raytheon Company common stockholders and net income attributable to Raytheon Company, and our actual weighted-average shares outstanding rather than the numbers presented within our consolidated financial statements, which are rounded to the nearest million. As a result, it may not be possible to recalculate EPS as presented in our consolidated financial statements. Furthermore, it may not be possible to recalculate EPS attributable to Raytheon Company common stockholders by adjusting EPS from continuing operations by EPS from discontinued operations.

We include all unvested stock awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, in the number of shares outstanding in our basic EPS calculation as they are considered participating securities. As a result, we have included all of our outstanding unvested awards of restricted stock, as well as restricted stock units (RSUs) and Long-term Performance Plan (LTPP) awards that meet the retirement eligible criteria in our calculation of basic EPS. We disclose EPS for common stock and unvested stock-based payment awards, and separately disclose distributed and undistributed earnings. Distributed earnings represent common stock dividends and dividends earned on unvested awards of restricted stock and stock-based payment awards of retirement eligible employees. Undistributed earnings represent earnings that were available for distribution but were not distributed. Common stock and unvested stock-based payment awards earn dividends equally.

As described in “Note 11: Redeemable Noncontrolling Interests,” prior to our acquisition of Vista Equity Partners’ interest in Forcepoint in the fourth quarter of 2019, we recorded redeemable noncontrolling interest related to their interest. We reflected the redemption value adjustments for redeemable noncontrolling interest in both the basic and diluted EPS calculation for the portion of redemption value that was in excess of the fair value of noncontrolling interest.

Employee Stock Plans [Policy Text Block]

Employee Stock Plans—Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award. The expense is recognized over the employees’ requisite service period, generally the vesting period of the award. The expense is amortized over the service period using the graded vesting method for our restricted stock and RSUs and the straight-line amortization method for our LTPP. The expense related to our Forcepoint long-term incentive plans is recognized over the requisite service period when achievement of the performance conditions is considered probable. We account for forfeitures when they occur, consistent with our government recovery accounting practice. The gross excess tax benefit received upon exercise of stock options or vesting of a stock-based award, if any, is reflected in the consolidated statements of cash flows as an operating activity.

Risks and Uncertainties [Policy Text Block]

Risks and Uncertainties—We provide a wide range of technologically advanced products, services and solutions for principally governmental customers in the U.S. and abroad, and are subject to certain business risks specific to that industry. Total sales to the U.S. government, excluding foreign military sales, were 69% of total net sales in 2019, 68% of total net sales in 2018 and 67% of total net sales in 2017. Total sales to customers outside the U.S., including foreign military sales through the U.S. government, were 29% of total net sales in 2019, 30% of total net sales in 2018 and 32% of total net sales in 2017. 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. Sales to international customers may be affected by changes in the priorities and budgets of international customers and geopolitical uncertainties, which may be driven by changes in threat environments, volatility in worldwide economic conditions, regional and local economic and political factors, U.S. foreign policy and other risks and uncertainties.

Remaining Performance Obligations [Policy Text Block]

Remaining Performance Obligations—Remaining performance obligations represents the transaction price of firm orders for which work has not been performed and excludes unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity (IDIQ)). As of December 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $48,752 million. We expect to recognize revenue on approximately half and three-quarters of the remaining performance obligations over the next 12 and 24 months, respectively, with the remainder recognized thereafter.

Accounting Standards [Policy Text Block]

Accounting Standards—In August 2018, the Financial Accounting Standards Board (FASB) issued ASU 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820), which eliminates the disclosure requirement of the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and modifies certain disclosure requirements related to Level 3 recurring and nonrecurring fair value measurements. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Effective January 1, 2019, we elected to early adopt the requirements of the new standard on a prospective basis. The standard did not have an impact on our financial position, results of operations or liquidity.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-24): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Effective January 1, 2019, we elected to early adopt the requirements of the new standard on a prospective basis. The standard did not have a material impact on our financial position, results of operations or liquidity.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use asset and lease liability for most lease arrangements. Effective January 1, 2019, we adopted the requirements of the new lease standard using the modified retrospective approach, applying the new lease requirements at the beginning of the earliest period presented. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allows us to carry forward the historical lease classification. We did not elect the practical expedient to use hindsight in determining the lease term and in assessing impairment of right-of-use assets. The standard resulted in the recognition of operating lease right-of-use assets of $805 million and operating lease liabilities of $841 million, of which $194 million was classified as current and is included in other current liabilities in our consolidated balance sheet, as of December 31, 2018, with immaterial changes to other balance sheet accounts. The standard had no impact on our results

of operations or cash flows. In addition, new disclosures are provided to enable users to assess the amount, timing and uncertainty of cash flows arising from leases.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows companies to reclassify stranded tax effects resulting from the 2017 Act, from accumulated other comprehensive income to retained earnings. These stranded tax effects refer to the tax amounts included in accumulated other comprehensive income at the previous 35% U.S. statutory tax rate, for which the related deferred tax asset or liability was remeasured to the new 21% U.S. corporate statutory federal tax rate in the period of the 2017 Act enactment. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and can be applied either in the period of adoption or retrospectively to each period impacted by the 2017 Act. We elected to early adopt the new standard in the first quarter of 2018 and we elected to reclassify the stranded income tax effects of the 2017 Act from accumulated other comprehensive income to retained earnings in the period of adoption. This resulted in an increase to AOCL of $1,451 million and an increase in retained earnings of $1,451 million in the first quarter of 2018, almost all of which related to our pension and PRB plans, net. The standard did not have an impact on our results of operations or liquidity. Income tax effects remaining in accumulated other comprehensive income will be released into earnings as the related before tax amounts are reclassified to earnings.

Other new pronouncements adopted and issued but not effective until after December 31, 2019, including ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), did not and are not expected to have a material impact on our financial position, results of operations or liquidity.
