Accounting Policies

Accounting Policies	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Summary of Accounting Principles The Condensed Consolidated Financial Statements at September 30, 2020 and for the quarters and nine months ended September 30, 2020 and 2019 are unaudited, and in the opinion of management include adjustments of a normal recurring nature necessary for a fair statement of the results for the interim periods. Raytheon Intelligence & Space (RIS) and Raytheon Missiles & Defense (RMD) follow a 4-4-5 fiscal calendar with results recorded from the April 3, 2020 merger close date through September 27, 2020 while Collins Aerospace Systems (Collins Aerospace) and Pratt & Whitney continue to use a quarter calendar end of September 30, 2020. The results reported in these Condensed Consolidated Financial Statements should not necessarily be taken as indicative of results that may be expected for the entire year, particularly in light of the completion of the Separation Transactions, Distributions and Raytheon Merger (each defined below). The financial information included herein should be read in conjunction with the financial statements and notes in our Annual Report to Shareowners (2019 Annual Report) incorporated by reference in our Annual Report on Form 10-K for calendar year 2019 (2019 Form 10-K). Separation Transactions and Distributions . On April 3, 2020, United Technologies Corporation (UTC) (since renamed Raytheon Technologies Corporation) completed the previously announced separation of its business into three independent, publicly traded companies – UTC, Carrier Global Corporation (Carrier) and Otis Worldwide Corporation (Otis) (such separations, the “Separation Transactions”). UTC distributed all of the outstanding shares of Carrier common stock and all of the outstanding shares of Otis common stock to UTC shareowners who held shares of UTC common stock as of the close of business on March 19, 2020, the record date for the distributions (the Distributions). UTC distributed 866,158,910 and 433,079,455 shares of common stock of Carrier and Otis, respectively in the Distributions, each of which was effective at 12:01 a.m., Eastern Time, on April 3, 2020. The historical results of Otis and Carrier are presented as discontinued operations and, as such, have been excluded from both continuing operations and segment results for all periods presented. Throughout this Quarterly Report on Form 10-Q, unless otherwise indicated, amounts and activity are presented on a continuing operations basis. Raytheon Merger. On April 3, 2020, following the completion of the Separation Transactions and the Distributions, pursuant to an Agreement and Plan of Merger dated June 9, 2019, as amended, UTC and Raytheon Company (Raytheon) completed their previously announced all-stock merger of equals transaction (the Raytheon Merger). Upon closing of the Raytheon Merger, Raytheon Company became a wholly-owned subsidiary of UTC, which changed its name to “Raytheon Technologies Corporation.” Unless the context otherwise requires, the terms “we,” “our,” “us,” “the Company,” “Raytheon Technologies,” and “RTC” mean United Technologies Corporation and its subsidiaries when referring to periods prior to the Raytheon Merger and to the combined company, Raytheon Technologies Corporation, when referring to periods after the Raytheon Merger. Unless the context otherwise requires, the terms “Raytheon Company,” or “Raytheon” mean Raytheon Company and its subsidiaries prior to the Raytheon Merger. UTC was determined to be the accounting acquirer in the merger and, as a result, the financial statements of Raytheon Technologies for the period ended and as of September 30, 2020 include Raytheon Company’s financial position and results of operations for the period subsequent to the completion of the Raytheon Merger on April 3, 2020. COVID-19 Pandemic. In March 2020, the coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. government. The pandemic has negatively affected the U.S. and global economy, disrupted global supply chains and financial markets, and resulted in significant travel restrictions, mandated facility closures and shelter-in-place and social distancing orders in numerous jurisdictions around the world. Raytheon Technologies is taking all prudent measures to protect the health and safety of our employees, such as practicing social distancing, performing deep cleaning in all of our facilities, and enabling our employees to work from home where possible. We have also taken appropriate actions to help support our communities in addressing the challenges posed by the pandemic, including the production and donation of personal protective equipment. Our business and operations and the industries in which we operate have been significantly impacted by public and private sector policies and initiatives in the U.S. and worldwide to address the transmission of COVID-19, such as the imposition of travel restrictions and the adoption of remote working. Additionally, public sentiments regarding air travel have also had a significant impact . We began to experience issues related to COVID-19 in the first quarter, primarily related to a limited number of facility closures, less than full staffing, and disruptions in supplier deliveries, most significantly in our Collins Aerospace and Pratt & Whitney businesses. However, our customers continued to receive our products and services during the first quarter and the outbreak did not have a significant impact on our operating results for the quarter ended March 31, 2020. The continued disruption to air travel and commercial activities and the significant restrictions and limitations on businesses, particularly within the aerospace and commercial airline industries, have negatively impacted global supply, demand and distribution capabilities. These conditions, which began in the second quarter of 2020, have continued in the third quarter of 2020. In particular, the unprecedented decrease in air travel resulting from the COVID-19 pandemic is adversely affecting our airline and airframer customers, and their demand for the products and services of our Collins Aerospace and Pratt & Whitney businesses. Based on recent public data and estimates, revenue passenger miles (RPMs) for the year ending December 31, 2020 could decline by more than 60% in comparison to the prior year due to the pandemic. As a result, our airline customers have reported significant reductions in fleet utilization, aircraft grounding and unplanned retirements, and have deferred and, in some cases, cancelled new aircraft deliveries. Airlines have shifted to cash conservation behaviors such as deferring engine maintenance due to lower flight hours and aircraft utilization, requesting extended payment terms, deferring delivery of new aircraft and spare engines and requesting discounts on engine maintenance. Some airline customers have filed for bankruptcy due to their inability to meet their financial obligations. Additionally, we are seeing purchase order declines in line with publicly communicated aircraft production volumes as original equipment manufacturer (OEM) customers delay and cancel orders. We continue to monitor these trends and are working closely with our customers. We are actively mitigating costs and adjusting production schedules to accommodate these declines in demand. We have also been taking actions to preserve capital and protect the long-term needs of our businesses, including cutting discretionary spending, significantly reducing capital expenditures and research and development spend, suspending our share buybacks, deferring merit increases and implementing temporary pay reductions, freezing non-essential hiring, repositioning employees to defense work, furloughing employees when needed, and personnel reductions. In the quarter and nine months ended September 30, 2020, we recorded total restructuring charges of $250 million and $685 million, respectively, primarily related to personnel reductions at our Collins Aerospace and Pratt & Whitney businesses to preserve capital and at our Corporate Headquarters due to consolidation from the Raytheon Merger. The former Raytheon Company businesses have not experienced significant facility closures or other significant business disruptions as a result of the COVID-19 pandemic. Given the significant reduction in business and leisure passenger air travel, the number of planes temporarily grounded, and continued travel restrictions that have resulted from the pandemic, we expect our future operating results, particularly those of our Collins Aerospace and Pratt & Whitney businesses to continue to be significantly negatively impacted. Our expectations regarding the COVID-19 pandemic and its potential financial impact are based on available information and assumptions that we believe are reasonable at this time; however, the actual financial impact is highly uncertain and subject to a wide range of factors and future developments. While we believe that the long-term outlook for the aerospace industry remains positive due to the fundamental drivers of air travel demand, there is significant uncertainty with respect to when and if commercial air traffic levels will begin to recover, and whether and at what point capacity will return to and/or exceed pre-COVID-19 levels. Our latest estimates are that this recovery may occur in 2023 or 2024. New information may emerge concerning the scope, severity and duration of the COVID-19 pandemic, as well as any worsening of the pandemic and whether there will be additional outbreaks of the pandemic, actions to contain its spread or treat its impact, and governmental, business and individuals’ actions taken in response to the pandemic (including restrictions and limitations on travel and transportation) among others. We considered the deterioration in general economic and market conditions primarily due to the COVID-19 pandemic to be a triggering event in the first and second quarters of 2020 requiring us to reassess our commercial aerospace business goodwill and intangibles valuations, as well as our significant assumptions of future cash flows from our underlying assets and potential changes in our liabilities. Beginning in the second quarter of 2020, our revenue at Collins Aerospace and Pratt & Whitney has been significantly negatively impacted by the decline in flight hours, aircraft fleet utilization, shop visits and commercial OEM deliveries. In order to evaluate the ongoing impact, in the second quarter of 2020 we updated our forecast assumptions of future business activity, which are subject to a wide range of uncertainties, including those noted above. Based upon our analysis, we concluded that the carrying value of two of our Collins Aerospace reporting units was greater than its respective fair value, and accordingly, recorded a goodwill impairment charge of $3.2 billion. In the third quarter of 2020, we updated our forecast assumptions for Collins Aerospace and determined that the resulting third quarter forecasts were in line with our second quarter forecasts. As such, we determined we did not have an additional goodwill impairment triggering event. Refer to “Note 2: Acquisitions, Dispositions, Goodwill and Other Intangible Assets” for additional information. Additionally, in the nine months ended September 30, 2020 we recorded write-downs of non-goodwill assets and significant unfavorable Estimate at Completion (EAC) adjustments in our Collins Aerospace and Pratt & Whitney businesses primarily related to: • increased estimated credit losses on both our receivables and contract assets of $48 million and $357 million in the quarter and nine months ended September 30, 2020, respectively, • an unfavorable EAC adjustment on a Pratt & Whitney commercial engine aftermarket contract due to lower estimated revenues driven by a change in the estimated maintenance coverage period of $334 million in both the quarter and nine months ended September 30, 2020, • contract asset and inventory impairments at Collins Aerospace due to the impact of lower estimated future customer activity resulting from the expected acceleration of fleet retirements of a commercial aircraft of $13 million and $146 million in the quarter and nine months ended September 30, 2020, respectively, • an unfavorable EAC adjustment of $129 million in both the quarter and nine months ended September 30, 2020 related to lower estimated revenues due to the restructuring of a customer contract at Pratt & Whitney, • an $89 million impairment of commercial aircraft program assets at Pratt & Whitney in both the quarter and nine months ended September 30, 2020, • the impairment of a Collins Aerospace trade name of $57 million in total, in the first and second quarters of 2020, • unfavorable EAC adjustments on commercial aftermarket contracts at Pratt & Whitney based on a change in estimated future customer activity of $48 million in total, in the second and third quarters of 2020, and • an unfavorable EAC adjustment at Pratt & Whitney related to a shift in overhead costs to military contracts of $44 million in the second quarter of 2020. As described further in “Note 5: Commercial Aerospace Industry Assets and Commitments” within the Notes to the Consolidated Financial Statements in our 2019 Annual Report, we have significant exposure related to our airline and airframer customers, including significant accounts receivable and contract assets balances. Given the uncertainty related to the severity and length of the pandemic, as well as any worsening of the pandemic and whether there will be additional outbreaks of the pandemic and its impact across the aerospace industry, we may be required to record additional charges or impairments in future periods. Although the impact of COVID-19 on our commercial markets is significant, we currently believe we have sufficient liquidity to withstand the potential impacts of COVID-19. With the completion of the Separation Transactions, the Distributions and the Raytheon Merger, we have a balanced and diversified portfolio of both aerospace and defense businesses which we believe will help mitigate the impacts of the COVID-19 pandemic and future business cycles. Summary of Accounting Principles. As a result of the Raytheon Merger and the Separation Transactions, several of our accounting policies have been modified and certain additional polices have been added. The following represents the significant accounting principles of Raytheon Technologies Corporation. Consolidation and Classification. The Condensed Consolidated Financial Statements include the accounts of Raytheon Technologies Corporation, 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, the duration of our contracts or programs is utilized for our operating cycle, which is generally longer than one year. Included within our current assets and liabilities are contract assets and liabilities related to our aftermarket and development arrangements, which can generally span up to fifteen years. As a result of the Separation Transactions, the Distributions and the Raytheon Merger, certain reclassifications have been made to the prior year amounts to conform to the current year presentation. These reclassifications include the presentation of current assets and liabilities based upon the duration of our operating cycle, the reclassification of certain unbilled accounts receivable from accounts receivable, net to contract assets, reclassifications of lease amortization within our presentation of cash flows, reclassifications within our segment presentation, and the reclassification of the historical Otis and Carrier results to discontinued operations. 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. As discussed above, the full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations, financial condition, and cash flows, including sales, expenses, reserves and allowances, asset recoverability and EAC adjustments, will depend on future developments that are highly uncertain, including new information that may emerge concerning COVID-19 and related containment and treatment actions, as well as the economic impact on local, regional, national and international customers and markets. We have made estimates of the impact of COVID-19 within our financial statements and there may be changes to those estimates in future periods. Other future events, including regarding COVID-19, 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. Cash and Cash Equivalents. Cash and cash equivalents includes cash on hand, demand deposits and short-term cash investments that are highly liquid in nature and have original maturities of three months or less. On occasion, we are required to maintain cash deposits with certain banks with respect to contractual obligations related to acquisitions or divestitures or other legal obligations. This restricted cash is excluded from cash and cash equivalents and is included in other assets, current and other assets on our Condensed Consolidated Balance Sheet. Accounts Receivable. Accounts receivable are stated at the net amount expected to be collected. The allowance for credit losses is established to provide for the expected lifetime credit losses by evaluating factors such as customer creditworthiness, historical payment and loss experiences, current economic conditions and the age and status of outstanding receivables. See the Accounting Pronouncements section below for additional information as to how we develop our allowance for credit losses under Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Unbilled receivables represent revenues that are not currently billable to the customer under the terms of the contract and include unbilled amounts under commercial contracts where payment is subject to the passage of time. These items are expected to be billed and collected in the normal course of business. Other unbilled receivables not just subject to the passage of time are included in Contract assets in the Condensed Consolidated Balance Sheet, and are generally classified as current. Contract Assets and Liabilities. Contract assets and liabilities represent the difference in the timing of revenue recognition from receipt of cash from our customers. Contract assets reflect revenue recognized and performance obligations satisfied or partially satisfied in advance of customer billing. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. Contract assets and contract liabilities are generally classified as current. See “Note 6: Contract Assets and Liabilities” for further discussion of contract assets and liabilities. Inventory. Inventory is stated at the lower of cost or estimated realizable value and are primarily based on first-in, first-out (FIFO) or average cost methods. Valuation reserves for excess, obsolete, and slow-moving inventory are estimated by comparing the inventory levels of individual parts to both future sales forecasts or production requirements and historical usage rates in order to identify inventory where the resale value or replacement value is less than inventoriable cost. Other factors that management considers in determining the adequacy of these reserves include whether individual inventory parts meet current specifications and can be substituted for a part currently being sold or used as a service part, overall market conditions, and other inventory management initiatives. Manufacturing costs are allocated to current production contracts. Equity Method Investments. Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in Other assets on the Condensed Consolidated Balance Sheet. Under this method of accounting, our share of the net earnings or losses of the investee is included in Operating profit on the Condensed Consolidated Statement of Operations since the activities of the investee are closely aligned with the operations of the business segment holding the investment. We evaluate our equity method investments whenever events or changes in circumstance indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period. Customer Financing Assets. Customer financing assets (CFA) relate to our commercial aerospace businesses in which we provide financing to airline customers. Our financing predominately relates to products under lease, and to a lesser extent, notes and lease receivables. We record revenue from lease assets by applying Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 842: Leases, and from interest income on the notes and lease receivables. Interest income from notes and financing leases and rental income from operating lease assets is included in Other income (expense), net in the Condensed Consolidated Statement of Operations, while gains or losses on sales of operating lease assets are included in product sales and cost of sales. The current portion of these financing arrangements are aggregated in Other assets, current and the non-current portion of these financing arrangements are aggregated in CFA in the Condensed Consolidated Balance Sheet. The increases and decreases in CFA from funding, receipts and certain other activity, are reflected as Investing Activities in the Condensed Consolidated Statement of Cash Flows. The products under lease assets are valued at cost and reviewed for impairment when circumstances indicate that the related carrying amounts may not be recoverable. Notes and lease receivables are valued at the net amount expected to be collected. Reserves for credit losses on notes and lease receivables relate to specifically identified receivables that are evaluated individually for impairment. For notes and lease receivables, we determine a specific reserve for exposure based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral in connection with the evaluation of credit risk and collectability. As of September 30, 2020 and December 31, 2019 the reserves related to CFA are not material. At September 30, 2020 and December 31, 2019, we did not have any significant balances that are considered to be delinquent, on non-accrual status, past due 90 days or more, or considered to be impaired. Business Combinations. Once a business is acquired, the fair value of the identifiable assets acquired and liabilities assumed is determined with the excess cost recorded to goodwill. As required, a preliminary fair value is determined once a business is acquired, with the final determination of the fair value being completed within the one year measurement period from the date of acquisition. Goodwill and Intangible Assets. Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to impairment testing annually, or more frequently if events or changes in circumstances indicate the asset might be impaired. The impairment test compares carrying values of the reporting units to its estimated fair values. If the carrying value exceeds the fair value then the carrying value is reduced to fair value. In developing our estimates for the fair value of our reporting units, significant judgment is required in the determination of the appropriateness of using a qualitative assessment or quantitative assessment. For these quantitative assessments that are performed, fair value is primarily based on income approaches using a discounted cash flow method and relief from royalty method, which have significant assumptions including sales growth rates, projected operating profit, terminal growth rates, discount rates and royalty rates. Such assumptions are subject to variability from year to year and are directly impacted by, among other things, global market conditions. Intangible assets consist of patents, trademarks/tradenames, customer relationships, exclusivity assets, developed technology and other intangible assets including collaboration assets. Acquired intangible assets are recognized at fair value in purchase accounting and then finite lived-intangible assets are amortized to cost of sales and selling, general & administrative expenses over the applicable useful lives. Exclusivity assets are commercial aerospace payments made to secure certain contractual rights to provide product on new aircraft platforms. We classify amortization of such payments as a reduction of sales. Such payments are capitalized when there are distinct rights obtained and there are sufficient incremental cash flows to support the recoverability of the assets established. Otherwise, the applicable portion of the payments are expensed. Consideration paid on these contractual commitments is capitalized when it is no longer conditional. Useful lives of finite-lived intangible assets are estimated based upon the nature of the intangible asset and the industry in which the intangible asset is used. These intangible assets are amortized based on the pattern in which the economic benefits of the intangible assets are consumed, as represented by the underlying cash flows, which may result in an amortization method other than straight-line. For both our commercial aerospace collaboration assets and exclusivity arrangements, the pattern of economic benefit generally results in no amortization during the development period with amortization beginning as programs enter full rate production and aftermarket cycles. If a pattern of economic benefit cannot be reliably determined or if straight-line amortization approximates the pattern of economic benefit, a straight-line amortization method may be used. The range of estimated useful lives is as follows: Years Collaboration assets 30 Customer relationships and related programs 1 to 32 Developed technology 5 to 25 Patents & trademarks 4 to 40 Exclusivity assets 5 to 25 Leases. We account for leases in accordance with ASC Topic 842: Leases. Under Topic 842, the right-of-use model requires a lessee to record a right-of-use asset and a lease liability on the Condensed Consolidated Balance Sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the Condensed Consolidated Statement of Operations. We enter into lease agreements for the use of real estate space, vehicles, information technology equipment, and certain other equipment under both operating and finance leases. We determine if an arrangement contains a lease at inception. Operating leases are included in Operating lease right-of-use assets, Accrued liabilities for the current portion of our operating lease liabilities, and Operating lease liabilities in our Condensed Consolidated Balance Sheet. Finance leases are not considered significant to our Condensed Consolidated Balance Sheet or Condensed Consolidated Statement of Operations. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments, and use the implicit rate when readily determinable. We determine our incremental borrowing rate through market sources including relevant industry rates. Our lease right-of-use assets also include any initial direct costs and lease pre-payments made at or before the commencement date and are reduced for any lease incentives received at or before the commencement date. Certain of our leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. We exclude variable payments from lease right-of-use assets and lease liabilities, to the extent not considered fixed, and instead, expense variable payments as incurred. Variable lease expense and lease expense for short duration contracts are not a material component of lease expense. Some of our leases include the option 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. Lease expense is generally recognized on a straight-line basis over the lease term. In limited instances we act as a lessor, primarily for commercial aerospace engines, the majority of which are classified as operating leases. These leases are not significant to our Condensed Consolidated Balance Sheet or Condensed Consolidated Statement of Operations. Other Long-Lived Assets. We evaluate the potential impairment of other long-lived assets whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. If the carrying value of other long-lived assets held and used exceeds the sum of the undiscounted expected future cash flows, the carrying value is written down to 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. Income Taxes. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, associated interest expense has also been recognized. We recognize accrued interest related to unrecognized tax benefits in interest expense. Penalties, if incurred, would be recognized as a component of income tax expense. State income tax amounts are generally included in income tax expense; however state income tax payments related to our RIS and RMD segments are generally recoverable through the pricing of products and services to the U.S. government. Accordingly, these state income taxes are allocated to contracts and reclassified to administrative and selling expenses when paid (recovered) or otherwise agreed as allocable with the U.S. government. On December 22, 2017 the Tax Cuts and Jobs Act of 2017 (TCJA) was enacted. The TCJA includes a provision that imposes a tax on Global Intangible Low-Taxed Income (GILTI) beginning in 2018. GILTI is a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The FASB has provided that companies subject to GILTI have the option to account for the GILTI tax as a period cost if and when incurred, or to recognize deferred taxes for temporary d

Business Combination, Recognized Identifiable Assets Acquired, Goodwill, and Liabilities Assumed, Net [Abstract]
Acquisitions, Dispositions, Goodwill and Other Intangible Assets [Text Block]	Acquisitions, Dispositions, Goodwill and Other Intangible Assets Business Acquisitions. As noted above, on April 3, 2020, pursuant to the Agreement and Plan of Merger dated June 9, 2019, as amended (the Raytheon Merger Agreement) UTC and Raytheon Company completed their previously announced all-stock merger of equals, following the completion by UTC of the Separation Transactions and Distributions. Raytheon Company (previously NYSE:RTN) shares ceased trading prior to the market open on April 3, 2020, and each share of Raytheon common stock was converted in the merger into the right to receive 2.3348 shares of UTC common stock previously traded on the NYSE under the ticker symbol “UTX.” Upon closing of the Raytheon Merger, UTC’s name was changed to “Raytheon Technologies Corporation,” and its shares of common stock began trading as of April 3, 2020 on the NYSE under the ticker symbol “RTX.” Total consideration is calculated as follows: (dollars, in millions, except per share amounts and exchange ratio) Amount Fair value of RTC common stock issued for Raytheon Company outstanding common stock and vested equity awards $ 33,067 Fair value attributable to pre-merger service for replacement equity awards 99 Total merger consideration $ 33,166 The fair value of RTC common stock issued for Raytheon Company outstanding common stock and vested equity awards is calculated as follows: (dollars and shares, in millions, except per share amounts and exchange ratio) Amount Number of Raytheon Company common shares outstanding as of April 3, 2020 277.3 Number of Raytheon Company stock awards vested as a result of the Raytheon Merger (1) 0.4 Total outstanding shares of Raytheon Company common stock and equity awards entitled to merger consideration 277.7 Exchange ratio (2) 2.3348 Shares of RTC common stock issued for Raytheon Company outstanding common stock and vested equity awards 648.4 Price per share of RTC common stock (3) $ 51.00 Fair value of RTC common stock issued for Raytheon Company outstanding common stock and vested equity awards $ 33,067 (1) Represents Raytheon Company stock awards that vested as a result of the Raytheon Merger, which is considered a “change in control” for purposes of the Raytheon 2010 Stock Plan. Certain Raytheon Company restricted stock awards and Raytheon Company restricted stock unit (RSU) awards, issued under the Raytheon 2010 Stock Plan vested on an accelerated basis as a result of the Raytheon Merger. Such vested awards were converted into the right to receive RTC common stock determined as the product of (1) the number of vested awards, and (2) the exchange ratio. (2) The exchange ratio is equal to 2.3348 shares of UTC common stock for each share of Raytheon Company common stock in accordance with the Raytheon Merger Agreement. (3) The price per share of RTC common stock is based on the RTC opening stock price as of April 3, 2020. Preliminary Allocation of Consideration Transferred to Net Assets Acquired. We are accounting for the Raytheon Merger under the acquisition method and are required to measure identifiable assets acquired and liabilities assumed of the acquiree (Raytheon Company) at the fair values on the closing date. The following amounts represent the preliminary determination of the fair value of identifiable assets acquired and liabilities assumed from the Raytheon Merger. As of September 30, 2020, the majority of the valuation studies necessary to determine the fair market value of the assets acquired and liabilities assumed have been reviewed and finalized; however, our assessment of certain contingencies including loss contracts and environmental liabilities, pension and postretirement benefit obligations and taxes remain open for completion of the related valuation analyses. We expect to finalize the purchase price allocation process in the first quarter of 2021 when we finalize our valuations and reviews. Any potential adjustments made could be material in relation to the preliminary values presented below. (dollars, in millions) Cash and cash equivalents $ 3,208 Accounts receivable 1,997 Inventory 705 Contract assets 6,023 Other assets, current 930 Future income tax benefits 14 Fixed assets 4,732 Intangible assets: 19,130 Customer relationships 12,900 Tradenames/trademarks 5,430 Developed technology 800 Other assets 2,139 Total identifiable assets acquired 38,878 Accounts payable 1,455 Accrued liabilities 3,237 Contract liabilities 2,991 Long-term debt, including current portion 4,700 Future pension and postretirement benefit obligation 10,641 Other long-term liabilities 3,455 Total liabilities acquired 26,479 Total identifiable net assets 12,399 Goodwill 20,801 Redeemable noncontrolling interest (34) Total consideration transferred $ 33,166 Fair value adjustments to Raytheon Company’s identified assets and liabilities included an increase in fixed assets of $1.1 billion and a preliminarily estimated increase to future pension and postretirement benefit obligations of $2.6 billion. The preliminarily estimated increase in future pension and postretirement benefit obligations primarily relates to remeasurement of the liability based on market conditions on the Raytheon Merger closing date. For further information, see “Note 10: Employee Benefit Plans.” In determining the fair value of identifiable assets acquired and liabilities assumed, a review was conducted for any significant contingent assets or liabilities existing as of such closing date. The preliminary assessment did not note any significant contingencies related to existing legal or government action. The fair values of the customer relationship intangible assets were determined by using an income approach. Under this approach, the estimated future cash flows attributable to the asset are adjusted to exclude the future cash flows that can be attributed to supporting assets, such as trade names or fixed assets. Both the amount and the duration of the cash flows are considered from a market participant perspective. Our estimates of market participant future cash flows included forecasted revenue growth rates, remaining developmental effort, operational performance including company specific synergies, program life cycles, material and labor pricing, and other relevant customer, contractual and market factors. Where appropriate, the net cash flows are probability-adjusted to reflect the uncertainties associated with the underlying assumptions, including cancellation rates related to backlog, government demand for sole-source and recompete contracts and win rates for recompete contracts, as well as the risk profile of the net cash flows utilized in the valuation. The probability-adjusted future cash flows are then discounted to present value, using an appropriate discount rate that requires judgment by management. The customer relationship intangible assets are being amortized based on the pattern of economic benefits we expect to realize over the estimated economic life of the underlying programs. The fair value of the tradename intangible assets were determined utilizing the relief from royalty method which is a form of the income approach. Under this method, a royalty rate based on observed market royalties is applied to projected revenue supporting the tradename and discounted to present value, using an appropriate discount rate that requires judgment by management. The tradename intangible assets have been determined to have an indefinite life. The developed technology intangible assets are being amortized based on the pattern of economic benefits. The intangible assets included above consist of the following: (dollars, in millions) Estimated Estimated Acquired customer relationships $ 12,900 25 years Acquired tradenames 5,430 Indefinite Acquired developed technology 800 5 to 7 years Total identifiable intangible assets $ 19,130 We also identified customer contractual obligations on loss making programs and recorded liabilities of $218 million related to these programs based on the difference between the actual expected operating loss and a normalized operating profit. These liabilities will be liquidated based on the expected pattern of expenses incurred on these contracts. We recorded $20.8 billion of goodwill as a result of the Raytheon Merger which primarily relates to expected synergies from combining operations and the value of the existing workforce. The Raytheon Merger creates a premier systems provider with advanced technologies to address rapidly growing segments within aerospace and defense. The Raytheon Merger offers complementary technologies and creates additional growth opportunities while delivering benefits to our shareowners, customers and employees. With our technological and research and development capabilities, Raytheon Technologies will deliver innovative and cost-effective solutions aligned with the highest customer priorities. The goodwill generated as a result of the Raytheon Merger is nondeductible for tax purposes. Merger-Related Costs. Merger-related costs have been expensed as incurred. In the quarter and nine months ended September 30, 2020, approximately $26 million and $125 million, respectively, of transaction and integration costs have been incurred which excludes $20 million of transactions costs related to the divestitures required for regulatory approval discussed further in the “Dispositions” section below. These costs were recorded in Selling, general and administrative expenses within the Condensed Consolidated Statement of Operations. Supplemental Pro-Forma Data. Raytheon Company’s results of operations have been included in RTC’s financial statements for the period subsequent to the completion of the Raytheon Merger on April 3, 2020. The following unaudited supplemental pro-forma data presents consolidated information as if the Raytheon Merger had been completed on January 1, 2019. The pro-forma results were calculated by combining the results of Raytheon Technologies with the stand-alone results of Raytheon Company for the pre-acquisition periods, which were adjusted to account for certain costs that would have been incurred during this pre-acquisition period. The results below reflect Raytheon Technologies on a continuing basis, in order to more accurately represent the structure of Raytheon Technologies after completion of the Separation Transactions and the Raytheon Merger. Quarter Ended September 30, Nine Months Ended September 30, (dollars in millions, except per share amounts) 2020 2019 2020 2019 Net sales $ 14,747 $ 18,752 $ 47,668 $ 54,790 Income (loss) from continuing operations attributable to common shareowners 174 1,817 (2,328) 5,065 Basic earnings (loss) per share of common stock from continuing operations $ 0.12 $ 1.20 $ (1.54) $ 3.36 Diluted earnings (loss) per share of common stock from continuing operations 0.11 1.20 (1.54) 3.34 The unaudited supplemental pro-forma data above includes the following significant adjustments made to account for certain costs which would have been incurred if the acquisition had been completed on January 1, 2019, as adjusted for the applicable tax impact. As the merger was completed on April 3, 2020, the pro-forma adjustments in the table below only include the required adjustments through April 3, 2020.

(7) Reflects the amortization of the fair market value adjustment related to Raytheon Company. (8) Reflects the elimination of amortization recognized on deferred commissions that are eliminated in purchase accounting. Dispositions. As discussed further in “Note 3: Discontinued Operations,” on April 2, 2020, Carrier and Otis entered into a Separation and Distribution Agreement with UTC (since renamed Raytheon Technologies Corporation), pursuant to which, among other things, UTC agreed to separate into three independent, publicly traded companies – UTC, Otis and Carrier and distribute all of the outstanding common stock of Carrier and Otis to UTC shareowners who held shares of UTC common stock as of the close of business on March 19, 2020. UTC distributed 866,158,910 and 433,079,455 shares of common stock of Carrier and Otis, respectively in the Distributions. As a result of the Distributions, Carrier and Otis are now independent publicly traded companies. In May 2020, in order to meet the requirements for regulatory approval of the Raytheon Merger, we completed the sale of our airborne tactical radios business for $231 million in cash, net of transaction-related costs. The business was part of our RIS segment. As the transaction occurred subsequent to the Raytheon Merger, the gain of $199 million was not recorded in the Condensed Consolidated Statement of Operations, but rather was recorded as an adjustment to the fair value of net assets acquired in the preliminary allocation of consideration transferred to net assets acquired in the Raytheon Merger, as discussed further above. Income before taxes related to the disposed business for the period from the closing of the Raytheon Merger to disposal date was not material. In the third quarter of 2020, in accordance with conditions imposed for regulatory approval of the Raytheon Merger, we completed the sale of our Collins Aerospace military Global Positioning System (GPS) and space-based precision optics businesses for $2.3 billion in cash, resulting in an aggregate pre-tax gain, net of transaction costs, of $580 million ($253 million after tax), of which $608 million was included in Other income (expense), net partially offset by $20 million of aggregate transaction costs included in Selling, general and administrative costs and an $8 million expense included in Non-service pension (income) expense within our Condensed Consolidated Statement of Operations. Income before taxes for 2020, through the date of sale, and for full year 2019 for these businesses were $94 million and $153 million, respectively. Goodwill. Changes in our goodwill balances for the nine months ended September 30, 2020 were as follows: (dollars in millions) Balance as of Acquisitions and Divestitures Impairment Losses Foreign Currency Translation and Other Balance as of September 30, 2020 Collins Aerospace Systems (1) $ 35,025 $ (890) $ (3,183) $ 190 $ 31,142 Pratt & Whitney 1,563 — — — 1,563 Raytheon Intelligence & Space — 8,781 — 2 8,783 Raytheon Missiles & Defense — 11,540 — 2 11,542 Total Segments 36,588 19,431 (3,183) 194 53,030 Eliminations and other 21 472 — 1 494 Total $ 36,609 $ 19,903 $ (3,183) $ 195 $ 53,524 (1) The change in Acquisitions and Divestitures is primarily driven by the sales of the Collins Aerospace businesses described above. The Company reviews goodwill for impairment annually or more frequently if events or changes in circumstances indicate the asset might be impaired. The Company has been monitoring the deterioration in general economic and market conditions primarily due to the COVID-19 pandemic. Beginning in the second quarter of 2020, we observed several airline customer bankruptcies, delays and cancellations of aircraft purchases by airlines, fleet retirements and repositioning of OEM production schedules. These factors contributed to a deterioration of our expectations regarding the timing of a return to pre-COVID-19 commercial flight activity, which further reduced our expectations regarding future sales and cash flows. We considered these factors to be a triggering event in the second quarter of 2020, requiring impairment evaluation of goodwill, intangible assets and other assets in our commercial aerospace businesses, Collins Aerospace and Pratt & Whitney. Impairment evaluations at Collins Aerospace and Pratt & Whitney resulted in several other charges as further discussed in “Note 1: Basis of Presentation and Summary of Accounting Principles.” These charges were primarily due to declines in expected future commercial air traffic, airline bankruptcies, or other impacts such as accelerated fleet retirements, announced program delays and expected changes to contract terms. We also evaluated amortizable intangible assets and identified no impairments. In the second quarter of 2020, we evaluated the Collins Aerospace and Pratt & Whitney reporting units for goodwill impairment and determined that the carrying values of two of the six Collins Aerospace reporting units exceeded the sum of discounted future cash flows, resulting in goodwill impairments of $3.2 billion. Collins Aerospace discounted future cash flow estimates were developed for three scenarios: a base case, a downside case, and an upside case. These scenarios included assumptions regarding future airline flight activity, out of warranty hours on original equipment, expected repairs, upgrades and replacements, future OEM manufacturing schedules and related environmental assumptions, including individuals’ desire to return to normal travel, business needs to travel, and potential cures or vaccines to prevent or reduce the effects of COVID-19. These estimates require a significant amount of judgment and are subject to change based upon factors outside our control. We weighted the three scenarios as follows: 50% for the base case, 40% for the downside case, and 10% for the upside case, and used these weightings, as we believe they reflect the risks and opportunities relative to our current estimates. Goodwill impairment was not indicated for any of the other reporting units evaluated for impairment in any of these scenarios. For these other reporting units, the reporting unit that was closest to impairment was a reporting unit at Collins Aerospace, with a fair value in excess of book value, including goodwill, of $1.4 billion or 19%. Material changes in these estimates could occur and result in additional impairments in future periods. If the discount rate used for the impairment analysis increased or decreased by 25 basis points, the impairments of the two Collins Aerospace reporting units would have increased by $1.2 billion or decreased by $1.3 billion, respectively. If the cash flows were decreased or increased by 10% the impairments would have increased by $2.5 billion or decreased by $2.1 billion, respectively. The Company continuously monitors for events and circumstances that could negatively impact the key assumptions in determining fair value, including long-term revenue growth projections, profitability, discount rates, recent market valuations from transactions by comparable companies, volatility in the Company’s market capitalization, and general industry, market and macro-economic conditions. In the third quarter of 2020, we updated our forecast assumptions for Collins Aerospace and determined that the resulting third quarter forecasts were in line with our second quarter forecasts. As such, we determined we did not have an additional goodwill impairment triggering event. It is possible that future changes in such circumstances, including a more prolonged and/or severe COVID-19 pandemic than originally anticipated, or future changes in the variables associated with the judgments, assumptions and estimates used in assessing the fair value of our reporting units, would require the Company to record a non-cash impairment charge. Intangible Assets. Identifiable intangible assets are comprised of the following: September 30, 2020 December 31, 2019 (dollars in millions) Gross Amount Accumulated Gross Amount Accumulated Amortized: Patents and trademarks $ 47 $ (34) $ 47 $ (34) Collaboration assets 4,982 (1,001) 4,862 (920) Exclusivity assets 2,476 (281) 2,386 (275) Developed technology and other 1,691 (339) 890 (217) Customer relationships 30,007 (4,694) 17,750 (3,392) $ 39,203 $ (6,349) $ 25,935 $ (4,838) Unamortized: Trademarks and other 8,710 — 3,376 — Total $ 47,913 $ (6,349) $ 29,311 $ (4,838) Exclusivity assets represent payments made to our customers to secure certain contractual rights that are capitalized when distinct rights are obtained and sufficient incremental cash flows to support the recoverability of the assets have been established. Otherwise, the applicable portion of the payments is recorded as a reduction in revenue. Intangible assets are tested for impairment when events occur that indicate that the net book value will not be recovered over future cash flows. Given the deterioration in general economic and market conditions primarily due to the COVID-19 pandemic, we performed an assessment of our amortizable intangible assets and recorded $40 million and $17 million in the first and second quarters of 2020, respectively, related to the impairment of an indefinite-lived tradename intangible assets at Collins Aerospace, with no additional impairment of intangible assets identified in the quarter ended September 30, 2020. With the exception of this tradename, the intangible asset that was closest to impairment was another tradename at Collins Aerospace with a fair value in excess of book value of approximately $70 million, or 4%. We will continue to evaluate the impact on our customers and our business in future periods which may result in a different conclusion. Amortization of intangible assets for the quarters and nine months ended September 30, 2020 and 2019 were $599 million and $1,506 million and $318 million and $933 million, respectively. The following is the expected amortization of intangible assets for the years 2020 through 2025. (dollars in millions) Remaining 2020 2021 2022 2023 2024 2025 Amortization expense $ 631 $ 2,523 $ 1,989 $ 2,101 $ 2,166 $ 2,030

The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock appreciation rights and stock options, when the average market price of the common stock is lower than the exercise price of the related stock awards during the period because the effect would be anti-dilutive. In addition, the computation of diluted earnings per share excludes the effect of the potential exercise of stock awards when the awards’ assumed proceeds exceed the average market price of the common shares during the period. For the quarter and nine months ended September 30, 2020, the number of stock awards excluded from the computation was 38.1 million and 31.5 million, respectively. For the quarter and nine months ended September 30, 2019, the number of stock awards excluded from the computation was 8.0 million and 11.0 million, respectively. All outstanding stock awards are excluded in the computation of diluted earnings per share in the nine months ended September 30, 2020 because their effect was antidilutive due to the loss from continuing operations.

Under these factoring arrangements, the Company factored receivables of $5.4 billion during both the nine months ended September 30, 2020 and 2019. The cash received from these arrangements is reflected as cash provided by operating activities in the Condensed Consolidated Statement of Cash Flows. In certain of these factoring arrangements, for ease of administration, the Company will collect customer payments related to the factored receivables, which it then remits to the financial institutions. At September 30, 2020 and December 31, 2019, the Company had $8 million and $7 million, respectively, that was collected on behalf of the financial institutions and recorded as restricted cash and accrued liabilities. The net cash flows relating to these collections are reported as financing activities in the Condensed Consolidated Statement of Cash Flows. The changes in the allowance for expected credit losses related to Accounts receivable for the nine months ended September 30, 2020 were as follows: (dollars in millions) Balance as of December 31, 2019 $ 254 Current period provision for expected credit losses (1) 263 Write-offs charged against the allowance for expected credit losses (5) Other, net (2) 18 Balance as of September 30, 2020 $ 530 (1) The current provision for expected credit losses for the nine months ended September 30, 2020 includes $223 million of reserves driven by customer bankruptcies and additional reserves for credit losses primarily due to the current economic environment primarily caused by the COVID-19 pandemic.

Revenue from Contract with Customer [Abstract]
Revenue Recognition [Text Block]	Contract Assets and Liabilities Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. Total contract assets and contract liabilities as of September 30, 2020 and December 31, 2019 are as follows: (dollars in millions) September 30, 2020 December 31, 2019 Contract assets $ 9,617 $ 4,462 Contract liabilities, current (12,208) (9,014) Contract liabilities, non-current (included within Other long-term liabilities) (120) — Net contract liabilities $ (2,711) $ (4,552) Contract assets increased $5.2 billion during the nine months ended September 30, 2020 primarily due to the Raytheon Merger, which accounted for an increase of $5.3 billion. Contract liabilities increased $3.3 billion during the nine months ended September 30, 2020 primarily due to the Raytheon Merger, which accounted for an increase of $3.5 billion. We recognized revenue of $480 million and $2,288 million during the quarter and nine months ended September 30, 2020, respectively, related to contract liabilities as of January 1, 2020 and $770 million and $2,308 million during the quarter and nine months ended September 30, 2019, respectively, related to contract liabilities as of January 1, 2019. Our contract assets and liabilities also include amounts related to foreign government direct commercial sales contracts for precision guided munitions to certain Middle Eastern customers for which we have not yet obtained regulatory approval and licenses. We had approximately $1.2 billion of total contract value, recognized approximately $400 million of sales for work performed through the date of the Raytheon Merger and approximately $150 million of sales subsequent to the date of the Raytheon Merger through September 30, 2020, and received approximately $450 million in advances as of September 30, 2020 on these contracts. On a contract-by-contract basis, we had $200 million of net contract assets and $100 million of net contract liabilities related to these contracts pending the U.S. government approvals. Total contract assets include an allowance for credit losses of $169 million as of September 30, 2020. For additional information on the adoption of the Credit Loss Standard on January 1, 2020 see “Note 1: Basis of Presentation and Accounting Principles.” The increase in the allowance for the nine months ended September 30, 2020 includes incremental credit loss reserves of $127 million related to a number of airline customers that have filed for bankruptcy and additional reserves due to the current economic environment primarily caused by the COVID-19 pandemic. In addition, in the nine months ended September 30, 2020, we impaired $111 million of contract assets at Collins Aerospace due to the impact of lower estimated future customer activity principally driven by the expected acceleration of fleet retirements of a commercial aircraft, and in both the quarter and nine months ended September 30, 2020, we impaired $129 million of contract assets as a result of an unfavorable EAC adjustment related to lower estimated revenues due to the restructuring of a customer contract at Pratt & Whitney.

We use our commercial paper borrowings for general corporate purposes, including the funding of potential acquisitions, pension contributions, debt refinancing, dividend payments and repurchases of our common stock. The commercial paper notes outstanding have original maturities of not more than 90 days from the date of issuance. In preparation for and in anticipation of the Separation Transactions, the Distributions and the Raytheon Merger, the Company entered into and terminated a number of credit agreements. On February 11, 2020 and March 3, 2020, we terminated a $2.0 billion revolving credit agreement and a $4.0 billion term loan credit agreement, respectively. Upon termination, we repaid the $2.1 billion of borrowings outstanding on the $4.0 billion term loan credit agreement. On April 3, 2020, upon the completion of the Raytheon Merger, we terminated a $2.20 billion revolving credit agreement and a $2.15 billion multicurrency revolving credit agreement. On March 20, 2020 and March 23, 2020, we entered into two $500 million term loan credit agreements and borrowed $1.0 billion under these agreements in the first quarter of 2020. We terminated these agreements on May 5, 2020 and April 28, 2020, respectively, upon repayment. On March 16, 2020, we entered into a revolving credit agreement with various banks permitting aggregate borrowings of up to $5.0 billion which became available upon completion of the Raytheon Merger on April 3, 2020. This credit agreement matures on April 3, 2025. On May 6, 2020, we entered into a revolving credit agreement with various banks permitting aggregate borrowings of up to $2.0 billion. This credit agreement matures on May 5, 2021. As of September 30, 2020 we had revolving credit agreements with various banks permitting aggregate borrowings of up to $7.0 billion. In preparation for and in anticipation of the Separation Transactions and Distributions, the Company, Otis and Carrier issued and the Company repaid long-term debt in the nine months ended September 30, 2020, which are included in the tables below. On February 10, 2020, Otis entered into a term loan credit agreement providing for a $1.0 billion unsecured, unsubordinated 3-year term loan credit facility. Also on February 10, 2020, Carrier entered into a term loan credit agreement providing for a $1.75 billion unsecured, unsubordinated 3-year term loan credit facility. On March 27, 2020, Otis and Carrier drew on the full amounts of the term loans and distributed the full proceeds to Raytheon Technologies in connection with the Separation Transactions. UTC utilized those amounts to extinguish Raytheon Technologies’ short-term and long-term debt in order to not exceed the maximum applicable net indebtedness required by the Raytheon Merger Agreement. We had the following issuances of long-term debt during the nine months ended September 30, 2020, which is inclusive of issuances made by Otis and Carrier which were primarily used by the Company to extinguish Raytheon Technologies short-term and long-term debt, and therefore were treated as a distribution from discontinued operations within financing activities from continuing operation on our Condensed Consolidated Statement of Cash Flows: (dollars in millions) Issuance Date Description of Notes Aggregate Principal Balance May 18, 2020 2.250% notes due 2030 $ 1,000 3.125% notes due 2050 1,000 March 27, 2020 Term Loan due 2023 (Otis) (1) 1,000 Term Loan due 2023 (Carrier) (1) 1,750 February 27, 2020 1.923% notes due 2023 (1) 500 LIBOR plus 0.450% floating rate notes due 2023 (1) 500 2.056% notes due 2025 (1) 1,300 2.242% notes due 2025 (1) 2,000 2.293% notes due 2027 (1) 500 2.493% notes due 2027 (1) 1,250 2.565% notes due 2030 (1) 1,500 2.722% notes due 2030 (1) 2,000 3.112% notes due 2040 (1) 750 3.377% notes due 2040 (1) 1,500 3.362% notes due 2050 (1) 750 3.577% notes due 2050 (1) 2,000 $ 19,300 (1) The debt issuances and term loan draws reflect debt incurred by Otis and Carrier.

We had no issuances of long-term debt during the nine months ended September 30, 2019. We had the following repayments of long-term debt during the nine months ended September 30, 2020 and 2019: (dollars in millions) Repayment Date Description of Notes Aggregate Principal Balance May 19, 2020 3.650% notes due 2023 (1)(2) $ 410 May 15, 2020 EURIBOR plus 0.20% floating rate notes due 2020 (€750 million principal value) (2) 817 March 29, 2020 4.500% notes due 2020 (1)(2) 1,250 1.125% notes due 2021 (€950 million principal value) (1)(2) 1,082 1.250% notes due 2023 (€750 million principal value) (1)(2) 836 1.150% notes due 2024 (€750 million principal value) (1)(2) 841 1.875% notes due 2026 (€500 million principal value) (1)(2) 567 March 3, 2020 1.900% notes due 2020 (1)(2) 1,000 3.350% notes due 2021 (1)(2) 1,000 LIBOR plus 0.650% floating rate notes due 2021 (1)(2) 750 1.950% notes due 2021 (1)(2) 750 2.300% notes due 2022 (1)(2) 500 3.100% notes due 2022 (1)(2) 2,300 2.800% notes due 2024 (1)(2) 800 March 2, 2020 4.875% notes due 2020 (1)(2) 171 February 28, 2020 3.650% notes due 2023 (1)(2) 1,669 2.650% notes due 2026 (1)(2) 431 Total debt repayments during the nine months ended September 30, 2020 $ 15,174 July 15, 2019 1.950% notes due 2019 300 5.250% notes due 2019 300 Total debt repayments during the nine months ended September 30, 2019 $ 600 (1) In connection with the early repayment of outstanding principal, Raytheon Technologies recorded debt extinguishment costs of $703 million for the nine months ended September 30, 2020, which are classified as discontinued operations in our Condensed Consolidated Statement of Operations as we would not have had to redeem the debt, except for the Separation Transactions. No proceeds of the notes issued May 18, 2020 were used to fund the May 19, 2020 redemption. (2) Extinguishment of Raytheon Technologies short-term and long-term debt in order to not exceed the maximum net indebtedness required by the Raytheon Merger Agreement. On June 10, 2020, we completed an exchange offer with eligible holders of the outstanding notes of Goodrich Corporation maturing through 2046, Raytheon Company maturing through 2044 and Rockwell Collins Inc. maturing through 2047 (collectively, the “Subsidiary Notes”). An aggregate principal amount of approximately $8.2 billion of the Subsidiary Notes was exchanged for approximately $8.2 billion of Raytheon Technologies notes with identical interest rates, maturity dates, and redemption provisions, if any, as the Subsidiary Notes exchanged. Because the exchange was for substantially identical notes, the change was treated as a debt modification for accounting purposes with no gain or loss recognized. Long-term debt consisted of the following: (dollars in millions) September 30, 2020 December 31, 2019 4.875% notes due 2020 $ — $ 171 4.500% notes due 2020 — 1,250 1.900% notes due 2020 — 1,000 EURIBOR plus 0.20% floating rate notes due 2020 (€750 million principal value) — 831 3.125% notes due 2020 (2) 1,000 — 8.750% notes due 2021 250 250 3.100% notes due 2021 250 250 3.350% notes due 2021 — 1,000 LIBOR plus 0.650% floating rate notes due 2021 — 750 1.950% notes due 2021 — 750 1.125% notes due 2021 (€950 million principal value) — 1,053 2.300% notes due 2022 — 500 2.800% notes due 2022 1,100 1,100 3.100% notes due 2022 — 2,300 2.500% notes due 2022 (2) 1,100 — 1.250% notes due 2023 (€750 million principal value) — 831 3.650% notes due 2023 (1) 171 2,250 3.700% notes due 2023 400 400 2.800% notes due 2024 — 800 3.200% notes due 2024 950 950 1.150% notes due 2024 (€750 million principal value) — 831 3.150% notes due 2024 (2) 300 — 3.950% notes due 2025 (1) 1,500 1,500 1.875% notes due 2026 (€500 million principal value) — 554 2.650% notes due 2026 (1) 719 1,150 3.125% notes due 2027 (1) 1,100 1,100 3.500% notes due 2027 1,300 1,300 7.200% notes due 2027 (2) 382 — 7.100% notes due 2027 141 141 6.700% notes due 2028 400 400 7.000% notes due 2028 (2) 185 — 4.125% notes due 2028 (1) 3,000 3,000 7.500% notes due 2029 (1) 550 550 2.150% notes due 2030 (€500 million principal value) (1) 583 554 2.250% notes due 2030 (1) 1,000 — 5.400% notes due 2035 (1) 600 600 6.050% notes due 2036 (1) 600 600 6.800% notes due 2036 (1) 134 134 7.000% notes due 2038 159 159 6.125% notes due 2038 (1) 1,000 1,000 4.450% notes due 2038 (1) 750 750 5.700% notes due 2040 (1) 1,000 1,000 4.875% notes due 2040 (2) 600 — 4.700% notes due 2041 (2) 425 — 4.500% notes due 2042 (1) 3,500 3,500 4.800% notes due 2043 400 400 4.200% notes due 2044 (2) 300 — 4.150% notes due 2045 (1) 850 850 3.750% notes due 2046 (1) 1,100 1,100 4.050% notes due 2047 (1) 600 600 4.350% notes due 2047 1,000 1,000 4.625% notes due 2048 (1) 1,750 1,750 3.125% notes due 2050 (1) 1,000 — Other (including finance leases) 299 315 Total principal long-term debt 32,448 41,274 Other (fair market value adjustments, (discounts)/premiums, and debt issuance costs) 105 (315) Total long-term debt 32,553 40,959 Less: current portion 1,307 3,258 Long-term debt, net of current portion $ 31,246 $ 37,701 (1) We may redeem these notes at our option pursuant to their terms.

The average interest expense rate on our total borrowings for the quarters and nine months ended September 30, 2020 and 2019 was as follows: Quarter Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Average interest expense rate 4.2 % 3.6 % 4.0 % 3.7 % In the fourth quarter of 2020, we repaid the $1.0 billion of debt that matured on October 15, 2020, using cash on hand.

Income Taxes

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Our effective tax rate was 45.1% and 23.2% in the quarters ended September 30, 2020 and 2019, respectively. The increase in the effective tax rate for the quarter ended September 30, 2020 compared to the quarter ended September 30, 2019 is primarily due to the sales of the Collins Aerospace businesses, described in “Note 2: Acquisitions, Dispositions, Goodwill and Other Intangible Assets,” which increased the rate by 61.1%, partially offset by a 15.9% decrease in the rate associated with an update to the forecasted annualized effective tax rate (AETR) impact on prior quarter earnings and a 17.4% decrease in the rate associated with the state and non-U.S. tax rates related to the charges in the quarter driven by the current economic environment primarily due to the COVID-19 pandemic and our restructuring activities. For further discussion of these charges refer to “Note 1: Basis of Presentation and Summary of Accounting Principles” and “Note 11: Restructuring Costs.” The remaining 5.9% decrease is composed of various unrelated items, which individually and collectively are not significant. Our effective tax rate was (31.5)% and 13.4% in the nine months ended September 30, 2020 and 2019, respectively. The change in the effective tax rate for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 is primarily due to the goodwill impairment in second quarter of 2020, which was primarily non-deductible and which decreased the rate by 27.6%, a 16.3% decrease in the rate for the impairment of deferred tax assets as a result of the Separation Transactions or the Raytheon Merger and a 9.5% decrease in the rate primarily related to the sales of the Collins Aerospace businesses noted above, partially offset by the absence of the tax benefit related to the 2019 audit settlements, which decreased the prior year rate by 8.3%. The remaining increase of 0.2% is composed of various unrelated items, which individually and collectively are not significant. We conduct business globally and, as a result, Raytheon Technologies or one or more of our subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business we are subject to examination by taxing authorities throughout the world, including such major jurisdictions as Canada, China, France, Germany, India, Philippines, Poland, Singapore, the United Kingdom, and the United States. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 2009. In the ordinary course of business, there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. As a result of the Separation Transactions and the Distributions in April 2020, we transferred unrecognized tax benefits to Carrier and Otis of approximately $440 million in the second quarter of 2020. Pursuant to the terms of the separation agreements, certain other unrecognized tax benefits retained by Raytheon Technologies will be subject to indemnification. As a result of the Raytheon Merger, unrecognized tax benefits increased during the second quarter of 2020 by approximately $240 million due to inclusion of items related to pre-merger Raytheon Company tax periods. Additionally, it is reasonably possible that a net reduction within the range of $200 million to $300 million of unrecognized tax benefits may occur within the next 12 months as a result of the revaluation of uncertain tax positions arising from the issuance of legislation, regulatory or other guidance or developments in examinations, in appeals, or in the courts, or the closure of tax statutes. Interest on unrecognized tax benefits during the quarter ended September 30, 2020 and 2019 were $12 million and $11 million, respectively. The amount of interest accrued at September 30, 2020 was $138 million. Management has determined that the distributions of Carrier and Otis on April 3, 2020, and certain related internal business separation transactions, qualified as tax-free under applicable law. In making these determinations, we applied the tax law in the relevant jurisdictions to our facts and circumstances and obtained tax rulings from the relevant taxing authorities, tax opinions, and/or other external tax advice related to the concluded tax treatment. If the completed distributions of Carrier or Otis, in each case, or certain internal business separation transactions, were to fail to qualify for tax-free treatment, the Company could be subject to significant liabilities, and there could be material adverse impacts on the Company’s business, financial condition, results of operations and cash flows in future reporting periods. The Examination Division of the Internal Revenue Service (IRS) is currently auditing Raytheon Technologies tax years 2017 and 2018 and pre-merger Raytheon Company tax periods 2017, 2018 and 2019 as well as certain refund claims of Raytheon Company for tax years 2014, 2015 and 2016 filed prior to the Raytheon Merger. The Examination Division of the IRS is also auditing pre-acquisition Rockwell Collins fiscal tax years 2016 and 2017, which is projected to close within the next 6 months. As a result of the projected closure of the audit of Rockwell Collins fiscal tax years 2016 and 2017 as well as other potential settlements and statute of limitations expirations, it is reasonably possible that the Company may recognize non-cash gains in the range of $75 million to $125 million, primarily tax, within the next 6 months, including approximately $25 million prior to the end of 2020.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	Employee Benefit Plans Pension and Postretirement Plans. We sponsor both funded and unfunded domestic and foreign defined benefit pension and postretirement benefit (PRB) plans, and defined contribution plans. On April 3, 2020, UTC completed the Separation Transactions, which included the transfer of certain defined benefit plans from UTC to Otis and Carrier. The plans transferred were primarily international plans with the majority of the UTC defined benefit liability remaining with Raytheon Technologies. Upon separation, the employees within Otis and Carrier were effectively terminated from Raytheon Technologies. The terminations of approximately 3,400 domestic pension plan participants triggered a mid-year remeasurement of the UTC domestic plans. The remeasurement, which was calculated using discount rates and asset values as of April 3, 2020, resulted in a $2.4 billion increase to our pension liability, primarily due to a decrease in the fair market value of the plans’ assets since December 31, 2019. Historical amounts have been restated for discontinued operations. All service cost previously associated with Otis and Carrier is included in discontinued operations. For non-service pension (income) expense and the pension liability, only the portion related to the defined benefit plans transferred to Otis and Carrier as part of the Separation Transactions was reclassified to discontinued operations. Raytheon Company has both funded and unfunded domestic and foreign defined benefit pension and PRB plans. As of the merger date, the Raytheon Company plans were remeasured at fair value using accounting policies consistent with the UTC plans. The deferred pension and PRB plan losses included in Raytheon Company’s accumulated other comprehensive income (loss) as of the merger date were eliminated and are no longer subject to amortization in net periodic benefit (income) cost and postretirement benefit costs. Amounts prior to the merger date of April 3, 2020, do not include the Raytheon Company pension plan results. Contributions to our plans were as follows: Quarter Ended September 30, Nine Months Ended September 30, (dollars in millions) 2020 2019 2020 2019 US qualified and international defined benefit and PRB plans $ 22 $ 4 $ 64 $ 41 Defined contribution plans (1) 228 117 668 369 (1) Increase in contributions to our defined contribution plans is primarily due to contributions related to the Raytheon Company plans. Included in the contributions to employer sponsored defined contribution plans for the quarter and nine months ended September 30, 2020 is $24 million and $101 million, respectively, of additional contributions resulting from the 2019 amendment to the UTC domestic pension plans whereby plan participants ceased accrual of additional benefits for future service effective December 31, 2019 and began receiving additional employer contributions effective January 1, 2020 under the UTC domestic defined contribution plan. Future pension and postretirement benefit obligations on the Condensed Consolidated Balance Sheet consisted of the following: (dollars in millions) September 30, 2020 December 31, 2019 Long-term pension liabilities $ 13,499 $ 1,770 Long-term PRB liabilities 1,059 696 Other pension and PRB related items 130 21 Total long-term pension and PRB liabilities (1) $ 14,688 $ 2,487 (1) Increase in long-term pension and PRB liabilities is primarily due to liabilities acquired as part of the Raytheon Merger and the remeasurement of the UTC domestic defined benefit plans as a result of the Separation Transactions. The following table illustrates the components of net periodic benefit (income) expense for our defined pension and PRB plans: Pension Benefits Quarter Ended September 30, PRB Quarter Ended September 30, (dollars in millions) 2020 2019 2020 2019 Operating expense Service cost $ 149 $ 62 $ 2 $ — Non-operating expense Interest cost 465 300 10 7 Expected return on plan assets (827) (551) (4) — Amortization of prior service cost (credit) 13 4 (1) (10) Recognized actuarial net loss (gain) 86 60 (3) (3) Net settlement and curtailment loss (gain) 8 (96) — — Non-service pension (income) expense (255) (283) 2 (6) Total net periodic benefit (income) expense $ (106) $ (221) $ 4 $ (6) Pension Benefits Nine Months Ended September 30, PRB Nine Months Ended September 30, (dollars in millions) 2020 2019 2020 2019 Operating expense Service cost $ 328 $ 208 $ 5 $ 2 Non-operating expense Interest cost 1,170 942 26 23 Expected return on plan assets (2,162) (1,687) (9) (1) Amortization of prior service cost (credit) 39 13 (3) (32) Recognized actuarial net loss (gain) 255 158 (9) (9) Net settlement and curtailment loss (gain) 35 (88) — — Non-service pension (income) expense (663) (662) 5 (19) Total net periodic benefit (income) expense $ (335) $ (454) $ 10 $ (17) In the quarter ended September 30, 2019, we amended the UTC domestic defined benefit plans to cease accrual of additional benefits for future service and compensation for non-union participants effective December 31, 2019. Beginning January 1, 2020, these participants began receiving additional employer contributions under the UTC domestic defined contribution plan. We utilized the practical expedient and remeasured plan assets and pension benefit obligations for the affected pension plans as of the nearest month-end, August 31, 2019, resulting in a net actuarial loss of $425 million. This reflects a benefit obligation gain of $180 million resulting from the benefit plan change that was offset by remeasurement losses of $605 million. Additionally, as a result of the remeasurement, net periodic benefit income (excluding curtailment) decreased by approximately $10 million in the quarter ended September 30, 2019. In the quarter ended September 30, 2019, we recorded a curtailment gain of $98 million in the Condensed Consolidated Statement of Operations due to the recognition of previously unrecognized prior service credits for the affected pension plans. We have set aside assets in separate trusts, which we expect to be used to pay for certain nonqualified defined benefit and defined contribution plan obligations in excess of qualified plan limits. These assets are included in Other assets, current in our Condensed Consolidated Balance Sheet. The fair value of marketable securities held in trusts consisted of the following: (dollars in millions) September 30, 2020 December 31, 2019 Marketable securities held in trusts $ 847 $ —

Restructuring and Related Activities [Abstract]
Restructuring and Other Costs [Text Block]	Restructuring Costs Restructuring costs are generally expensed as incurred. All U.S. government unallowable restructuring costs related to the Raytheon Merger are recorded within Corporate expenses and other unallocated items, as these costs are not included in management’s evaluation of the segments’ performance, and as a result, there are no unallowable restructuring costs at the RIS and RMD segments. During the quarter and nine months ended September 30, 2020, we recorded net pre-tax restructuring costs totaling $250 million and $685 million, respectively, for new and ongoing restructuring actions. We recorded charges in the segments as follows: (dollars in millions) Quarter Ended September 30, 2020 Nine Months Ended September 30, 2020 Pratt & Whitney $ 68 $ 175 Collins Aerospace Systems 138 295 Corporate expenses and other unallocated items 44 215 Total $ 250 $ 685 Restructuring charges incurred during the quarter and nine months ended September 30, 2020 primarily relate to actions initiated during 2020 and 2019, and were recorded as follows: (dollars in millions) Quarter Ended September 30, 2020 Nine Months Ended September 30, 2020 Cost of sales $ 142 $ 330 Selling, general and administrative 103 350 Restructuring costs recorded within operating expenses 245 680 Non-service pension (income) expense 5 5 Total $ 250 $ 685 2020 Actions. During the quarter ended September 30, 2020, we recorded net pre-tax restructuring costs of $240 million, comprised of $139 million in Cost of sales, $96 million in Selling, general and administrative expenses and $5 million in Non-service pension expenses. During the nine months ended September 30, 2020, we recorded net pre-tax restructuring costs of $686 million, comprised of $339 million in Cost of sales, $342 million in Selling, general and administrative expenses and $5 million in Non-service pension expenses. The 2020 actions primarily relate severance and restructuring actions at Pratt & Whitney and Collins Aerospace in response to the anticipated impact on our operating results related to the current economic environment primarily caused by the COVID-19 pandemic, the Raytheon Merger, and ongoing cost reduction efforts including workforce reductions and the consolidation of field and manufacturing operations. The following table summarizes the accrual balance and utilization for the 2020 restructuring actions for the quarter and nine months ended September 30, 2020: (dollars in millions) Severance Facility Exit and Other Costs Total Quarter Ended September 30, 2020 Restructuring accruals at June 30, 2020 $ 395 $ — $ 395 Net pre-tax restructuring costs 232 8 240 Utilization, foreign exchange and other costs (166) (8) (174) Balance at September 30, 2020 $ 461 $ — $ 461 Nine Months Ended September 30, 2020 Restructuring accruals at December 31, 2019 $ — $ — $ — Net pre-tax restructuring costs 677 9 686 Utilization, foreign exchange and other costs (216) (9) (225) Balance at September 30, 2020 $ 461 $ — $ 461 The following table summarizes expected, incurred and remaining costs for the 2020 restructuring actions by segment: (dollars in millions) Expected Costs Incurred Quarter Ended Costs Incurred Quarter Ended Costs Incurred Quarter Ended Remaining Costs at September 30, 2020 Pratt & Whitney $ 198 $ — $ (130) $ (68) $ — Collins Aerospace Systems 309 (1) (146) (128) 34 Corporate expenses and other unallocated items 213 (1) (168) (44) — Total $ 720 $ (2) $ (444) $ (240) $ 34 We are targeting to complete the majority of the remaining workforce and facility related cost reduction actions during 2020 and 2021. 2019 Actions. During the quarter ended September 30, 2020, we recorded $9 million of net pre-tax restructuring costs for restructuring actions initiated in 2019 comprised of $7 million in Selling, general and administrative expenses and $2 million in Cost of sales. During the nine months ended September 30, 2020, we recorded net pre-tax restructuring costs totaling $5 million for restructuring actions initiated in 2019, including expense of $10 million in Selling, general and administrative expenses, partially offset by a reversal of $5 million in Cost of sales. The 2019 actions relate to ongoing cost reduction efforts, including workforce reductions, consolidation of field and manufacturing operations, and costs to exit legacy programs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments [Text Block]	Financial InstrumentsWe enter into derivative instruments primarily for risk management purposes, including derivatives designated as hedging instruments under the Derivatives and Hedging (Topic 815) of the FASB ASC and those utilized as economic hedges. We operate internationally and, in the normal course of business, are exposed to fluctuations in interest rates, foreign exchange rates and commodity prices. These fluctuations can increase the costs of financing, investing and operating the business. We have used derivative instruments, including swaps, forward contracts and options, to manage certain foreign currency, interest rate and commodity price exposures. The aggregate notional amount of our outstanding foreign currency hedges was $12.8 billion and $13.0 billion at September 30, 2020 and December 31, 2019, respectively. The following table summarizes the fair value and presentation in the Condensed Consolidated Balance Sheet for derivative instruments as of September 30, 2020 and December 31, 2019: (dollars in millions) Balance Sheet Location September 30, 2020 December 31, 2019 Derivatives designated as hedging instruments: Foreign exchange contracts Other assets, current $ 29 $ 23 Accrued liabilities (198) (166) Derivatives not designated as hedging instruments: Foreign exchange contracts Other assets, current $ 25 $ 23 Accrued liabilities (57) (116) The effect of cash flow hedging relationships on Accumulated other comprehensive income (loss) and on the Condensed Consolidated Statement of Operations for the quarters and nine months ended September 30, 2020 and 2019 are presented in the table below. The losses are attributable to foreign exchange contract activity and are generally recorded as a component of Product sales when reclassified from Accumulated other comprehensive income (loss). Quarter Ended September 30, Nine Months Ended September 30, (dollars in millions) 2020 2019 2020 2019 (Loss) gain recorded in Accumulated other comprehensive loss $ 117 $ (153) $ (98) $ (125) Loss reclassified from Accumulated other comprehensive loss into Product sales 37 20 93 40 The Company utilizes the critical terms match method in assessing derivatives for hedge effectiveness. Accordingly, the hedged items and derivatives designated as hedging instruments are highly effective.

Our available-for-sale securities include equity investments that are traded in active markets, either domestically or internationally, and are measured at fair value using closing stock prices from active markets. Our derivative assets and liabilities include foreign exchange contracts that are measured at fair value using internal models based on observable market inputs such as forward rates, interest rates, our own credit risk and our counterparties’ credit risks. As of September 30, 2020, there has not been any significant impact to the fair value of our derivative liabilities due to our own credit risk. Similarly, there has not been any significant adverse impact to our derivative assets based on our evaluation of our counterparties’ credit risks.

The standard allowed companies to reclassify to retained earnings the stranded tax effects in Accumulated other comprehensive income (loss) from the TCJA. We elected to reclassify the income tax effects of the TCJA from Accumulated other comprehensive income (loss) of $745 million to retained earnings, effective January 1, 2019. Amounts reclassified that relate to our defined benefit pension and postretirement plans include the amortization of prior service costs and actuarial net losses recognized during each period presented. These costs are recorded as components of net periodic pension benefit for each period presented. Additionally, in the quarter ended September 30, 2019, we recorded a

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entity Disclosure	Variable Interest Entities Pratt & Whitney holds a 61% net interest in the International Aero Engines AG (IAE) collaboration with MTU Aero Engines AG (MTU) and Japanese Aero Engines Corporation (JAEC) and a 49.5% ownership interest in IAE. IAE’s business purpose is to coordinate the design, development, manufacturing and product support of the V2500 program through involvement with the collaborators. Additionally, Pratt & Whitney, JAEC and MTU are participants in International Aero Engines, LLC (IAE LLC), whose business purpose is to coordinate the design, development, manufacturing and product support for the PW1100G-JM engine for the Airbus A320neo aircraft and the PW1400G-JM engine for the Irkut MC21 aircraft. Pratt & Whitney holds a 59% net interest and a 59% ownership interest in IAE LLC. IAE and IAE LLC retain limited equity with the primary economics of the programs passed to the participants. As such, we have determined that IAE and IAE LLC are variable interest entities with Pratt & Whitney the primary beneficiary. IAE and IAE LLC have, therefore, been consolidated. The carrying amounts and classification of assets and liabilities for variable interest entities in our Condensed Consolidated Balance Sheet are as follows: (dollars in millions) September 30, 2020 December 31, 2019 Current assets $ 6,519 $ 5,448 Noncurrent assets 894 894 Total assets $ 7,413 $ 6,342 Current liabilities $ 7,518 $ 6,971 Noncurrent liabilities 100 94 Total liabilities $ 7,618 $ 7,065

Guarantees

Service and Product Warranties and Product Performance Guarantees [Abstract]
Guarantees [Text Block]	Guarantees We extend a variety of financial, market value and performance guarantees to third parties. These instruments expire on various dates through 2024. Additional guarantees of project performance for which there is no stated value also remain outstanding. As of September 30, 2020 and December 31, 2019, the following guarantees related to continuing operations were outstanding: (dollars in millions) September 30, 2020 December 31, 2019 Maximum Potential Payment Carrying Amount of Liability Maximum Potential Payment Carrying Amount of Liability Commercial aerospace financing arrangements $ 333 $ 8 $ 333 $ 7 Third party guarantees (1) 374 4 48 — (1) Increase in guarantees is primarily due to the Raytheon Merger. We also have obligations arising from sales of certain businesses and assets, including those from representations and warranties and related indemnities for environmental, health and safety, tax and employment matters. The maximum potential payment related to these obligations is not a specified amount as a number of the obligations do not contain financial caps. The carrying amount of liabilities related to these obligations was $121 million and $166 million at September 30, 2020 and December 31, 2019, respectively. For additional information regarding the environmental indemnifications, see “Note 17: Commitments and Contingencies.” We accrue for costs associated with guarantees when it is probable that a liability has been incurred and the amount can be reasonably estimated. The most likely cost to be incurred is accrued based on an evaluation of currently available facts, and where no amount within a range of estimates is more likely, the minimum is accrued. We also provide service and warranty policies on our products and extend performance and operating cost guarantees beyond our normal service and warranty policies on some of our products, particularly commercial aircraft engines. In addition, we incur discretionary costs to service our products in connection with specific product performance issues. Liabilities for performance and operating cost guarantees are based upon future product performance and durability, and are largely estimated based upon historical experience. Adjustments are made to accruals as claims data and historical experience warrant. The changes in the carrying amount of service and product warranties and product performance guarantees for the nine months ended September 30, 2020 and 2019 are as follows: (dollars in millions) 2020 2019 Balance as of January 1 $ 1,033 $ 929 Warranties and performance guarantees issued 206 325 Settlements (229) (233) Other (10) (3) Balance as of September 30 $ 1,000 $ 1,018

Contingent Liabilities

Contingent Liabilities	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities [Text Block]	Commitments and Contingencies Summarized below are the matters previously described in “Note 16: Contingent Liabilities” within the Notes to the Consolidated Financial Statements in our 2019 Annual Report, incorporated by reference in our 2019 Form 10-K, updated as applicable. Except as otherwise noted, while we are unable to predict the final outcome, based on information currently available, we do not believe that resolution of any of the following matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition. Environmental. Our operations are subject to environmental regulation by federal, state and local authorities in the United States and authorities with jurisdiction over our foreign operations. As described in “Note 1: Basis of Presentation and Summary of Accounting Principles,” we have accrued for the costs of environmental remediation activities, including but not limited to investigatory, remediation, operating and maintenance costs and performance guarantees, and periodically reassess these amounts. We believe that the likelihood of incurring losses materially in excess of amounts accrued is remote. At September 30, 2020 and December 31, 2019, we had $801 million and $725 million, respectively, reserved for environmental remediation. Additional information pertaining to environmental matters is included in “Note 1: Basis of Presentation and Summary of Accounting Principles.” Commercial Aerospace Financing and Other Commitments. We had commercial aerospace financing and other contractual commitments of approximately $13.7 billion and $15.0 billion as of September 30, 2020 and December 31, 2019, respectively, on a gross basis before reduction for our collaboration partners’ share. These commitments primarily relate to financing commitments to our commercial aerospace industry customers and commitments to secure certain contractual rights to provide product on new aircraft platforms. In connection with our 2012 agreement to acquire Rolls-Royce’s ownership and collaboration interests in IAE, additional payments are due to Rolls-Royce contingent upon each hour flown through June 2027 by the V2500-powered aircraft in service as of the acquisition date. These flight hour payments, which are considered in other contractual commitments above, are being capitalized as collaboration intangible assets. Associated risks on these commitments are mitigated due to the fact that interest rates are variable during the commitment term and are set at the date of funding based on current market conditions, the fair value of the underlying collateral and the credit worthiness of the customers. As a result, the fair value of these financing commitments is expected to equal the amounts funded. Other Financing Arrangements. We have entered into standby letters of credit and surety bonds with financial institutions to meet various bid, performance, warranty, retention and advance payment obligations for us or our affiliates. We enter into these agreements to assist certain affiliates in obtaining financing on more favorable terms, making bids on contracts and performing their contractual obligations. The stated values of these letters of credit agreements and surety bonds totaled $4.7 billion as of September 30, 2020. Offset Obligations. We have entered into industrial cooperation agreements, sometimes in the form of either offset agreements or ICIP agreements, as a condition to obtaining orders for our products and services from certain customers in foreign countries. At September 30, 2020, the aggregate amount of our offset agreements, both agreed to and anticipated to be agreed to, had an outstanding notional value of approximately $12.7 billion. These agreements are designed to return economic value to the foreign country by requiring us to engage in activities supporting local defense or commercial industries, promoting a balance of trade, developing in-country technology capabilities or addressing other local development priorities. Offset agreements may be satisfied through activities that do not require a direct cash payment, including transferring technology, providing manufacturing, training and other consulting support to in-country projects, and the purchase by third parties (e.g., our vendors) of supplies from in-country vendors. These agreements may also be satisfied through our use of cash for activities such as subcontracting with local partners, purchasing supplies from in-country vendors, providing financial support for in-country projects and making investments in local ventures. Such activities may also vary by country depending upon requirements as dictated by their governments. We typically do not commit to offset agreements until orders for our products or services are definitive. The amounts ultimately applied against our offset agreements are based on negotiations with the customers and typically require cash outlays that represent only a fraction of the notional value in the offset agreements. Offset programs usually extend over several or more years and may provide for penalties in the event we fail to perform in accordance with offset requirements. Historically, we have not been required to pay any penalties of significance. Government Oversight. In the ordinary course of business, the Company and its subsidiaries and our properties are subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations and threatened legal actions and proceedings. For example, we are now, and believe that, in light of the current U.S. government contracting environment, we will continue to be the subject of one or more U.S. government investigations. Our contracts with the U.S. government are also subject to audits. Agencies that oversee contract performance include: the Defense Contract Audit Agency (DCAA), the Defense Contract Management Agency (DCMA), the Inspectors General of the U.S. Department of Defense (DoD) and other departments and agencies, the Government Accountability Office (GAO), the Department of Justice (DOJ), and Congressional Committees. Other areas of our business operations may also be subject to audit and investigation by these and other agencies. From time to time, agencies investigate or conduct audits to determine whether our operations are being conducted in accordance with applicable requirements. Such investigations and audits may be initiated due to a number of reasons, including as a result of a whistleblower complaint. Such investigations and audits could result in administrative, civil or criminal liabilities, including repayments, fines, treble or other damages, forfeitures, restitution, or penalties being imposed upon us, 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 may result in no adverse action against us. The U.S. government also reserves the right to debar a contractor from receiving new government contracts for fraudulent, criminal or other seriously improper conduct. The U.S. government could void any contracts found to be tainted by fraud. Like many defense contractors, we have received audit reports recommending the reduction of certain contract prices because, for example, cost or pricing data or cost accounting practices used to price and negotiate those contracts may not have conformed to government regulations. Some of these audit reports recommend that certain payments be repaid, delayed, or withheld, and may involve substantial amounts. We have made voluntary refunds in those cases we believe appropriate, have settled some allegations and, in some cases, continue to negotiate and/or litigate. The Company may be, and has been, required to make payments into escrow of disputed liabilities while the related litigation is pending. If the litigation is resolved in the Company’s favor, any such payments will be returned to the Company with interest. Our final allowable incurred costs for each year are also subject to audit and have, from time to time, resulted in disputes between us and the U.S. government, with litigation resulting at the Court of Federal Claims (COFC) or the Armed Services Board of Contract Appeals (ASBCA) or their related courts of appeals. In addition, the DOJ has, from time to time, convened grand juries to investigate possible irregularities by us. We also provide products and services to customers outside of the U.S., and those sales are subject to local government laws, regulations and procurement policies and practices. Our compliance with such local government regulations or any applicable U.S. government regulations (e.g., the Foreign Corrupt Practices Act (FCPA) and International Traffic in Arms Regulations (ITAR)) may also be investigated or audited. In addition, we accrue for liabilities associated with those matters that are probable and can be reasonably estimated. The most likely settlement amount to be incurred is accrued based upon a range of estimates. Where no amount within a range of estimates is more likely, then we accrue the minimum amount. Other than as specifically disclosed in this Form 10-Q, we do not expect these audits, investigations or disputes to have a material effect on our financial position, results of operations or liquidity, either individually or in the aggregate. Legal Proceedings. The Company and its subsidiaries are subject to various litigation matters across jurisdictions, updates to certain of which are set forth below. Cost Accounting Standards Claims As previously disclosed, in April 2019, a Divisional Administrative Contracting Officer (DACO) of the United States DCMA asserted a claim against Pratt & Whitney to recover overpayments of approximately $1.73 billion plus interest ($651 million at September 30, 2020). The claim is based on Pratt & Whitney’s alleged noncompliance with Cost Accounting Standards (CAS) from January 1, 2007 to March 31, 2019, due to its method of allocating independent research and development costs to government contracts. Pratt & Whitney believes that the claim is without merit and filed an appeal to the ASBCA on June 7, 2019. As previously disclosed, in December 2013, a DCMA DACO asserted a claim against Pratt & Whitney to recover overpayments of approximately $177 million plus interest ($109 million at September 30, 2020). The claim is based on Pratt & Whitney’s alleged noncompliance with CAS from January 1, 2005 to December 31, 2012, due to its method of determining the cost of collaborator parts used in the calculation of material overhead costs for government contracts. In 2014, Pratt & Whitney filed an appeal to the ASBCA. An evidentiary hearing was held and completed in June 2019. The parties concluded post-hearing briefing in January 2020, and now await a decision from the ASBCA. We continue to believe that the claim is without merit. In December 2018, a DCMA DACO issued a second claim against Pratt & Whitney that similarly alleges that its method of determining the cost of collaborator parts does not comply with the CAS for calendar years 2013 through 2017. This second claim demands payment of $269 million plus interest ($69 million at September 30, 2020), which we also believe is without merit and which Pratt & Whitney appealed to the ASBCA in January 2019. Thales-Raytheon Systems Matter As previously disclosed, in 2019, Raytheon Company received a subpoena from the Securities and Exchange Commission (SEC) seeking information in connection with an investigation into whether there were improper payments made by Thales-Raytheon Systems (TRS) or anyone acting on their behalf in connection with TRS or Raytheon Company contracts in certain Middle East countries since 2014. In the first quarter of 2020, the DOJ advised Raytheon Company it had opened a parallel investigation. In the third quarter of 2020, Raytheon Company received an additional subpoena from the SEC, seeking information and documents as part of its ongoing investigation. Raytheon Company maintains a rigorous anti-corruption compliance program, is cooperating fully with the SEC’s inquiry, and is examining whether there has been any conduct that is in violation of Raytheon Company policy. At this time, the Company is unable to predict the outcome of the SEC’s or DOJ’s inquiry. Based on the information available to date, however, we do not believe the results of this inquiry will have a material adverse effect on our financial condition, results of operations or liquidity. DOJ Investigation On October 8, 2020, the Company received a criminal subpoena from the DOJ seeking information and documents in connection with an investigation relating to financial accounting, internal controls over financial reporting, and cost reporting regarding Raytheon Company’s Missiles & Defense business since 2009. We are cooperating fully with the DOJ’s investigation. At this time, the Company is unable to predict the outcome of the investigation. Based on the information available to date, however, we do not believe the results of this inquiry will have a material adverse effect on our financial condition, results of operations or liquidity. Darnis, et al. On August 12, 2020, several former employees of UTC or its subsidiaries filed a putative class action complaint in the United States District Court for the District of Connecticut against the Company, Otis, Carrier, the former members of the UTC Board of Directors, and the members of the Carrier and Otis Boards of Directors (Geraud Darnis, et al. v. Raytheon Technologies Corporation, et al.). The complaint challenges the method by which UTC equity awards were converted to Company, Otis, and Carrier equity awards following the separation of UTC into three independent, publicly-traded companies on April 3, 2020. The complaint claims that the defendants are liable for breach of certain equity compensation plans and for breach of fiduciary duty, and also asserts claims under certain provisions of the Employee Retirement Income Security Act of 1974 (ERISA). We believe that the Company has meritorious defenses to these claims. At this time, the Company is unable to predict the outcome, or the possible range of loss, if any, which could result from this action. Other. As described in “Note 16: Guarantees,” we extend performance and operating cost guarantees beyond our normal warranty and service policies for extended periods on some of our products. We have accrued our estimate of the liability that may result under these guarantees and for service costs that are probable and can be reasonably estimated. We also have other commitments and contingent liabilities related to legal proceedings, self-insurance programs and matters arising out of the normal course of business. We accrue contingencies based upon a range of possible outcomes. If no amount within this range is a better estimate than any other, then we accrue the minimum amount. In the ordinary course of business, the Company and its subsidiaries are also routinely defendants in, parties to or otherwise subject to many pending and threatened legal actions, claims, disputes and proceedings. These matters are often based on alleged violations of contract, product liability, warranty, regulatory, environmental, health and safety, employment, intellectual property, tax and other laws. In some instances, claims for substantial monetary damages are asserted against the Company and its subsidiaries and could result in fines, penalties, compensatory or treble damages or non-monetary relief. We do not believe that these matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segment Financial DataOur operations, effective as of the date of the Raytheon Merger, are classified into four principal segments: Collins Aerospace, Pratt & Whitney, RIS and RMD. The segments are generally based on the management structure of the businesses and the grouping of similar operating companies, where each management organization has general operating autonomy over diversified products and services. The results of RIS and RMD reflect the period subsequent to the completion of the Raytheon Merger on April 3, 2020. See “Note 21: Segment Financial Data” within the Notes to the Consolidated Financial Statements in our 2019 Annual Report for a description of the Collins Aerospace and Pratt & Whitney segments. Raytheon Intelligence & Space is a leading developer and provider of integrated sensor and communication systems for advanced missions, including space-enabled information and multi-domain intelligence solutions, as well as electronic warfare solutions, advanced training and logistic services, and cyber and software solutions to intelligence, defense, federal and commercial customers worldwide. Raytheon Missiles & Defense is a leading designer, developer, integrator and producer of missile and combat systems for the armed forces of the U.S. and allied nations and a leader in integrated air and missile defense, large land- and sea-based radar solutions, command, control, communications, computers, cyber and intelligence solutions, naval combat and ship electronic and sensing systems, and undersea sensing and effects solutions. In conjunction with the Raytheon Merger, we revised our measurement of segment performance to reflect how management now reviews and evaluates operating performance. Under the new segment performance measurement, certain acquisition accounting adjustments are now excluded from segments’ results in order to better represent the ongoing operational performance of those segments. In addition, the majority of Corporate expenses are now allocated to the segments, excluding certain items that remain at Corporate because they are not included in management’s review of the segments’ results. Historical results, discussion and presentation of our business segments reflect the impact of these adjustments for all periods presented. Also as a result of the Raytheon Merger, we now present a FAS/CAS operating adjustment outside of segment results, which represents the difference between our service cost component of our pension and PRB expense under the Financial Accounting Standards (FAS) requirements of U.S. GAAP and our pension and PRB expense under U.S. government Cost Accounting Standards (CAS) primarily related to our RIS and RMD segments. Because the Collins Aerospace and Pratt & Whitney segments generally record pension and PRB expense on a FAS basis, historical results were not impacted by this change in segment reporting. Total sales and operating profit by segment include inter-segment sales which are generally recorded at prices approximating those that the selling entity is able to obtain on external sales for our Collins Aerospace and Pratt & Whitney segments, and at cost-plus a specified fee, which may differ from what the selling entity would be able to obtain on sales to external customers, for our RIS and RMD segments.

Related amortization expense is included in Acquisition accounting adjustments. We disaggregate our contracts from customers by geographic location, by customer and by sales type. Our geographic location is based on customer location, utilizing end user customer location where known or practical. In instances in which determining the end user customer is not known or practical, we utilize ship to location as the customer location. In addition, for our RIS and RMD segments, we disaggregate our contracts from customers by contract type. We believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Historical results have been recast to reflect the presentation of this disaggregation. Segment sales disaggregated by geographic region for the quarters ended September 30, 2020 and 2019 are as follows: 2020 2019 (dollars in millions) Collins Aerospace Systems Pratt & Whitney Raytheon Intelligence & Space Raytheon Missiles & Defense Other Total Collins Aerospace Systems Pratt & Whitney Raytheon Intelligence & Space Raytheon Missiles & Defense Other Total United States $ 2,378 $ 1,856 $ 2,933 $ 2,290 $ 109 $ 9,566 $ 3,269 $ 2,260 $ — $ — $ 3 $ 5,532 Asia Pacific 358 772 195 365 13 1,703 644 1,452 — — — 2,096 Middle East and North Africa 97 112 122 714 10 1,055 168 212 — — — 380 Europe 965 572 100 337 38 2,012 1,661 953 — — — 2,614 Canada and All Other 165 179 29 29 9 411 342 409 — — — 751 Consolidated net sales 3,963 3,491 3,379 3,735 179 14,747 6,084 5,286 — — 3 11,373 Inter-segment sales 311 3 295 59 (668) — 411 (1) — — (410) — Business segment sales $ 4,274 $ 3,494 $ 3,674 $ 3,794 $ (489) $ 14,747 $ 6,495 $ 5,285 $ — $ — $ (407) $ 11,373 Segment sales disaggregated by geographic region for the nine months ended September 30, 2020 and 2019 are as follows: 2020 2019 (dollars in millions) Collins Aerospace Systems Pratt & Whitney Raytheon Intelligence & Space Raytheon Missiles & Defense Other Total Collins Aerospace Systems Pratt & Whitney Raytheon Intelligence & Space Raytheon Missiles & Defense Other Total United States $ 8,027 $ 6,103 $ 5,498 $ 4,440 $ 156 $ 24,224 $ 9,590 $ 6,353 $ — $ — $ 9 $ 15,952 Asia Pacific 1,350 2,980 390 716 26 5,462 1,822 3,930 — — — 5,752 Middle East and North Africa 339 406 244 1,434 18 2,441 536 608 — — — 1,144 Europe 3,497 2,101 202 628 104 6,532 5,341 3,126 — — — 8,467 Canada and All Other 651 738 53 43 24 1,509 1,097 1,243 — — — 2,340 Consolidated net sales 13,864 12,328 6,387 7,261 328 40,168 18,386 15,260 — — 9 33,655 Inter-segment sales 1,050 6 601 123 (1,780) — 1,198 (3) — — (1,195) — Business segment sales $ 14,914 $ 12,334 $ 6,988 $ 7,384 $ (1,452) $ 40,168 $ 19,584 $ 15,257 $ — $ — $ (1,186) $ 33,655 Segment sales disaggregated by customer for the quarters ended September 30, 2020 and 2019 are as follows: 2020 2019 (dollars in millions) Collins Aerospace Systems Pratt & Whitney Raytheon Intelligence & Space Raytheon Missiles & Defense Other Total Collins Aerospace Systems Pratt & Whitney Raytheon Intelligence & Space Raytheon Missiles & Defense Other Total U.S. government (1) $ 1,238 $ 1,270 $ 2,879 $ 2,288 $ 72 $ 7,747 $ 1,222 $ 1,091 $ — $ — $ — $ 2,313 Foreign military sales through the U.S. government 34 325 185 828 — 1,372 64 335 — — — 399 Foreign government direct commercial sales 230 120 240 594 2 1,186 217 98 — — — 315 Commercial aerospace and other commercial 2,461 1,776 75 25 105 4,442 4,581 3,762 — — 3 8,346 Consolidated net sales 3,963 3,491 3,379 3,735 179 14,747 6,084 5,286 — — 3 11,373 Inter-segment sales 311 3 295 59 (668) — 411 (1) — — (410) — Business segment sales $ 4,274 $ 3,494 $ 3,674 $ 3,794 $ (489) $ 14,747 $ 6,495 $ 5,285 $ — $ — $ (407) $ 11,373 (1) Excludes foreign military sales through the U.S. government.

Accounting Policies (Policies)

Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2020
Accounting Policies [Abstract]
Consolidation, Policy	Consolidation and Classification. The Condensed Consolidated Financial Statements include the accounts of Raytheon Technologies Corporation, 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, the duration of our contracts or programs is utilized for our operating cycle, which is generally longer than one year. Included within our current assets and liabilities are contract assets and liabilities related to our aftermarket and development arrangements, which can generally span up to fifteen years. As a result of the Separation Transactions, the Distributions and the Raytheon Merger, certain reclassifications have been made to the prior year amounts to conform to the current year presentation. These reclassifications include the presentation of current assets and liabilities based upon the duration of our operating cycle, the reclassification of certain unbilled accounts receivable from accounts receivable, net to contract assets, reclassifications of lease amortization within our presentation of cash flows, reclassifications within our segment presentation, and the reclassification of the historical Otis and Carrier results to discontinued operations.
Use of Estimates, Policy	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. As discussed above, the full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations, financial condition, and cash flows, including sales, expenses, reserves and allowances, asset recoverability and EAC adjustments, will depend on future developments that are highly uncertain, including new information that may emerge concerning COVID-19 and related containment and treatment actions, as well as the economic impact on local, regional, national and international customers and markets. We have made estimates of the impact of COVID-19 within our financial statements and there may be changes to those estimates in future periods. Other future events, including regarding COVID-19, 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.
Cash and Cash Equivalents, Policy	Cash and Cash Equivalents. Cash and cash equivalents includes cash on hand, demand deposits and short-term cash investments that are highly liquid in nature and have original maturities of three months or less. On occasion, we are required to maintain cash deposits with certain banks with respect to contractual obligations related to acquisitions or divestitures or other legal obligations. This restricted cash is excluded from cash and cash equivalents and is included in other assets, current and other assets on our Condensed Consolidated Balance Sheet.
Receivable	Accounts Receivable. Accounts receivable are stated at the net amount expected to be collected. The allowance for credit losses is established to provide for the expected lifetime credit losses by evaluating factors such as customer creditworthiness, historical payment and loss experiences, current economic conditions and the age and status of outstanding receivables. See the Accounting Pronouncements section below for additional information as to how we develop our allowance for credit losses under Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Unbilled receivables represent revenues that are not currently billable to the customer under the terms of the contract and include unbilled amounts under commercial contracts where payment is subject to the passage of time. These items are expected to be billed and collected in the normal course of business. Other unbilled receivables not just subject to the passage of time are included in Contract assets in the Condensed Consolidated Balance Sheet, and are generally classified as current.
Contract with Customer, Contract Assets and Liabilities	Contract Assets and Liabilities. Contract assets and liabilities represent the difference in the timing of revenue recognition from receipt of cash from our customers. Contract assets reflect revenue recognized and performance obligations satisfied or partially satisfied in advance of customer billing. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. Contract assets and contract liabilities are generally classified as current. See “Note 6: Contract Assets and Liabilities” for further discussion of contract assets and liabilities.
Inventory, Policy	Inventory. Inventory is stated at the lower of cost or estimated realizable value and are primarily based on first-in, first-out (FIFO) or average cost methods. Valuation reserves for excess, obsolete, and slow-moving inventory are estimated by comparing the inventory levels of individual parts to both future sales forecasts or production requirements and historical usage rates in order to identify inventory where the resale value or replacement value is less than inventoriable cost. Other factors that management considers in determining the adequacy of these reserves include whether individual inventory parts meet current specifications and can be substituted for a part currently being sold or used as a service part, overall market conditions, and other inventory management initiatives. Manufacturing costs are allocated to current production contracts.
Equity Method Investments	Equity Method Investments. Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the
Financing Receivable	Customer Financing Assets. Customer financing assets (CFA) relate to our commercial aerospace businesses in which we provide financing to airline customers. Our financing predominately relates to products under lease, and to a lesser extent, notes and lease receivables. We record revenue from lease assets by applying Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 842: Leases, and from interest income on the notes and lease receivables. Interest income from notes and financing leases and rental income from operating lease assets is included in Other income (expense), net in the Condensed Consolidated Statement of Operations, while gains or losses on sales of operating lease assets are included in product sales and cost of sales. The current portion of these financing arrangements are aggregated in Other assets, current and the non-current portion of these financing arrangements are aggregated in CFA in the Condensed Consolidated Balance Sheet. The increases and decreases in CFA from funding, receipts and certain other activity, are reflected as Investing Activities in the Condensed Consolidated Statement of Cash Flows. The products under lease assets are valued at cost and reviewed for impairment when circumstances indicate that the related carrying amounts may not be recoverable. Notes and lease receivables are valued at the net amount expected to be collected. Reserves for credit losses on notes and lease receivables relate to specifically identified receivables that are evaluated individually for impairment. For notes and lease receivables, we determine a specific reserve for exposure based on the difference between the carrying value of the receivable and the estimated fair value of the related collateral in connection with the evaluation of credit risk and collectability. As of September 30, 2020 and December 31, 2019 the reserves related to CFA are not material. At September 30, 2020 and
Business Combinations Policy	Business Combinations. Once a business is acquired, the fair value of the identifiable assets acquired and liabilities assumed is determined with the excess cost recorded to goodwill. As required, a preliminary fair value is determined once a business is acquired, with the final determination of the fair value being completed within the one year measurement period from the date of acquisition.
Goodwill and Intangible Assets, Policy	Goodwill and Intangible Assets. Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to impairment testing annually, or more frequently if events or changes in circumstances indicate the asset might be impaired. The impairment test compares carrying values of the reporting units to its estimated fair values. If the carrying value exceeds the fair value then the carrying value is reduced to fair value. In developing our estimates for the fair value of our reporting units, significant judgment is required in the determination of the appropriateness of using a qualitative assessment or quantitative assessment. For these quantitative assessments that are performed, fair value is primarily based on income approaches using a discounted cash flow method and relief from royalty method, which have significant assumptions including sales growth rates, projected operating profit, terminal growth rates, discount rates and royalty rates. Such assumptions are subject to variability from year to year and are directly impacted by, among other things, global market conditions. Intangible assets consist of patents, trademarks/tradenames, customer relationships, exclusivity assets, developed technology and other intangible assets including collaboration assets. Acquired intangible assets are recognized at fair value in purchase accounting and then finite lived-intangible assets are amortized to cost of sales and selling, general & administrative expenses over the applicable useful lives. Exclusivity assets are commercial aerospace payments made to secure certain contractual rights to provide product on new aircraft platforms. We classify amortization of such payments as a reduction of sales. Such payments are capitalized when there are distinct rights obtained and there are sufficient incremental cash flows to support the recoverability of the assets established. Otherwise, the applicable portion of the payments are expensed. Consideration paid on these contractual commitments is capitalized when it is no longer conditional. Useful lives of finite-lived intangible assets are estimated based upon the nature of the intangible asset and the industry in which the intangible asset is used. These intangible assets are amortized based on the pattern in which the economic benefits of the intangible assets are consumed, as represented by the underlying cash flows, which may result in an amortization method other than straight-line. For both our commercial aerospace collaboration assets and exclusivity arrangements, the pattern of economic benefit generally results in no amortization during the development period with amortization beginning as programs enter full rate production and aftermarket cycles. If a pattern of economic benefit cannot be reliably determined or if straight-line amortization approximates the pattern of economic benefit, a straight-line amortization method may be used. The range of estimated useful lives is as follows: Years Collaboration assets 30 Customer relationships and related programs 1 to 32 Developed technology 5 to 25 Patents & trademarks 4 to 40 Exclusivity assets 5 to 25
Leases	Leases. We account for leases in accordance with ASC Topic 842: Leases. Under Topic 842, the right-of-use model requires a lessee to record a right-of-use asset and a lease liability on the Condensed Consolidated Balance Sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the Condensed Consolidated Statement of Operations. We enter into lease agreements for the use of real estate space, vehicles, information technology equipment, and certain other equipment under both operating and finance leases. We determine if an arrangement contains a lease at inception. Operating leases are included in Operating lease right-of-use assets, Accrued liabilities for the current portion of our operating lease liabilities, and Operating lease liabilities in our Condensed Consolidated Balance Sheet. Finance leases are not considered significant to our Condensed Consolidated Balance Sheet or Condensed Consolidated Statement of Operations. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments, and use the implicit rate when readily determinable. We determine our incremental borrowing rate through market sources including relevant industry rates. Our lease right-of-use assets also include any initial direct costs and lease pre-payments made at or before the commencement date and are reduced for any lease incentives received at or before the commencement date. Certain of our leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. We exclude variable payments from lease right-of-use assets and lease liabilities, to the extent not considered fixed, and instead, expense variable payments as incurred. Variable lease expense and lease expense for short duration contracts are not a material component of lease expense. Some of our leases include the option 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. Lease expense is generally recognized on a straight-line basis over the lease term. In limited instances we act as a lessor, primarily for commercial aerospace engines, the majority of which are classified as operating leases. These leases are not significant to our Condensed Consolidated Balance Sheet or Condensed Consolidated Statement of Operations.
Impairment or Disposal of Long-Lived Assets, Policy	Other Long-Lived Assets. We evaluate the potential impairment of other long-lived assets whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. If the carrying value of other long-lived assets held and used exceeds the sum of the undiscounted expected future cash flows, the carrying value is written down to 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.
Income Tax, Policy	Income Taxes. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, associated interest expense has also been recognized. We recognize accrued interest related to unrecognized tax benefits in interest expense. Penalties, if incurred, would be recognized as a component of income tax expense. State income tax amounts are generally included in income tax expense; however state income tax payments related to our RIS and RMD segments are generally recoverable through the pricing of products and services to the U.S. government. Accordingly, these state income taxes are allocated to contracts and reclassified to administrative and selling expenses when paid (recovered) or otherwise agreed as allocable with the U.S. government. On December 22, 2017 the Tax Cuts and Jobs Act of 2017 (TCJA) was enacted. The TCJA includes a provision that imposes a tax on Global Intangible Low-Taxed Income (GILTI) beginning in 2018. GILTI is a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The FASB has provided that companies subject to GILTI have the option to account for the GILTI tax as a period cost if and when incurred, or to recognize deferred taxes for temporary differences, including outside basis differences, expected to reverse as GILTI. We have elected to account for GILTI as a period cost, as incurred.
Revenue	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. Collins Aerospace and Pratt & Whitney primarily serve commercial and government customers in both the OEM and aftermarket parts and services markets of the aerospace industry, while RIS and RMD primarily provide products and services to government customers in the defense market. 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 contracts that are directly with a foreign government, 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. A performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the customer. Some of our contracts with customers contain a single performance obligation, while others contain multiple performance obligations most commonly when a contract contains multiple distinct units (such as engines or certain aerospace components) or spans multiple phases of the product life-cycle such as production, maintenance and support. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as the performance obligation is satisfied. When there are multiple performance obligations within a contract, we allocate the transaction price to each performance obligation based on its standalone selling price when available. If standalone selling price is not available, we estimate the standalone selling price of each performance obligation, which is generally based on an expected cost plus a margin approach. We consider the contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price, including contractual discounts, contract incentive payments, estimates of award fees and other sources of variable consideration, when determining the transaction price of each contract. When reasonably able to estimate, we include variable consideration in the transaction price 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. These estimates are based on historical experience, anticipated performance and our best judgment at the time. We also consider whether our contracts contain a significant financing component, which they generally do not. Timing of the satisfaction of performance obligations varies across our businesses due to our diverse product and service mix, customer base, and contractual terms. Performance obligations are satisfied as of a point in time for certain aerospace components, engines, and spare parts. Revenue is recognized when control of the product transfers to the customer, generally upon product shipment. Since billing also typically occurs upon product shipment, we generally do not have contract assets or contract liabilities balances related to point in time sales. Performance obligations are satisfied over-time if the customer receives the benefits as we perform work, if the customer controls the asset as it is being produced (continuous transfer of control), or if the product being produced for the customer has no alternative use and we have a contractual right to payment for performance to date. We recognize revenue on an over-time basis for substantially all defense contracts and certain long-term aerospace OEM and aftermarket contracts. Substantially all of our defense business revenue, which primarily relates to our RIS and RMD segments, is recognized over time because of the continuous transfer of control to our customers. For performance obligations satisfied over time, revenue is recognized on a percentage of completion basis using costs incurred to date relative to total estimated costs at completion to measure progress. Incurred costs represent work performed, which correspond with and best depict transfer of control to the customer. Contract costs can include labor, materials, subcontractors’ costs, or other direct costs and indirect costs. Our contracts with the U.S. government are typically 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 80-90% 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 Condensed Consolidated Balance Sheet. For our U.S. government cost-type contracts, the customer generally pays us for our 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 advance payments in excess of revenue recognized and present it as Contract liabilities on the Condensed Consolidated Balance Sheet. For certain of our long-term aftermarket contracts, revenue is recognized over the contract period. We generally account for such contracts as a series of daily performance obligations to stand ready to provide spare parts, product maintenance and aftermarket services. These arrangements include the sale of spare parts with integral services to our customers, and are generally classified as Service sales, with the corresponding costs classified in Cost of services sold, within the Condensed Consolidated Statement of Operations. Revenue is primarily recognized on a percentage of completion basis using costs incurred to date relative to total estimated costs at completion to measure progress, as sufficient historical evidence indicates that the cost of performing services under the contract is incurred on an other-than-straight-line basis. For some of our long-term aftermarket contracts, we receive payment prior to our work being completed, resulting in a contract liability balance, while for others, we perform work in advance of payment, resulting in a contract asset balance. Contract modifications are routine as contracts are often modified to account for changes in contract specifications or requirements. We consider contract modifications to exist when the modification either creates new or changes existing enforceable rights and obligations. Contract modifications for goods or services that are not distinct are accounted for as part of the existing contract either on a cumulative catch-up basis or prospective basis depending on the nature of the modification. Loss provisions on contracts are recognized to the extent that estimated contract costs exceed the estimated consideration from the products or services contemplated under the contractual arrangement. For new commitments, we generally record loss provisions at contract signing except for certain contracts under which losses are recorded upon receipt of the purchase order that obligates us to perform. For existing commitments, anticipated losses on contractual arrangements are recognized in the period in which losses become evident. In estimating losses, products contemplated under contractual arrangements include firm quantities of product sold under contract and, in the commercial engine and wheels and brakes businesses, future highly probable sales of replacement parts required by regulation that are expected to be sold subsequently for incorporation into the original equipment. In our commercial engine and wheels and brakes businesses, when the OEM product is sold for a loss, but the combined OEM and aftermarket arrangement for each individual sales campaign is profitable, we record OEM product losses at the time of product delivery. We review our Estimate at Completion (EACs) on significant contracts on a periodic basis and for others, no less than annually or when a change in circumstances warrant a modification to a previous estimate. Due to the nature of the work required to be performed on many of the Company’s performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment by management on a contract by contract basis. 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 including consideration of customer-directed delays or reductions in scheduled deliveries, and technical and other specific contract requirements including customer activity levels and variable consideration based upon that activity. Management’s judgment related to these considerations has become increasingly more significant given the current economic environment primarily caused by the COVID-19 pandemic. Management must make assumptions and estimates regarding contract revenue and costs, including estimates of labor productivity and availability, the complexity and scope of the work to be performed, the availability and cost of materials, the length of time to complete the performance obligation, execution by our subcontractors, the availability and timing of funding from our customer, overhead cost rates, and current and past service cost and frequency driven by estimated aircraft and engine utilization and estimated useful lives of components, among others. Cost estimates may 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. If cash is paid to a customer to satisfy our offset obligations it is recorded as a reduction in the transaction price. Changes in estimates of net sales, cost of sales and the related impact to operating profit are recognized on a cumulative catch-up basis, which recognizes the cumulative effect of the profit changes on current and prior periods based on a performance obligation’s percentage of completion in the current period. A significant change in one or more of these estimates could affect the profitability of one or more of our performance obligations. Our EAC adjustments also include the establishment of loss provisions on our contracts accounted for on a percentage of completion basis. Net EAC adjustments had the following impact on our operating results: Quarter Ended September 30, Nine Months Ended September 30, (dollars in millions, except per share amounts) 2020 2019 2020 2019 Operating profit (loss) $ (462) $ 4 $ (592) $ (77) Income (loss) from continuing operations attributable to common shareowners (1) (365) 3 (468) (61) Diluted earnings (loss) per share from continuing operations attributable to common shareholders (1) $ (0.24) $ — $ (0.36) $ (0.07) (1) Amounts reflect a U.S. statutory tax rate of 21%, which approximates our effective tax rate on our EAC adjustments. For additional discussion on significant unfavorable EAC adjustments see the COVID-19 Pandemic discussion above. In the quarters ended September 30, 2020 and 2019, revenue was reduced by $231 million and increased by $1 million, respectively, for performance obligations satisfied (or partially satisfied) in previous periods. In the nine months ended September 30, 2020 and 2019, revenue was reduced by $432 million and $114 million, respectively, for performance obligations satisfied (or partially satisfied) in previous periods. This primarily relates to EAC adjustments that impacted revenue. As a result of the Raytheon Merger, Raytheon Company’s contracts accounted for on a percentage of completion basis were reset to zero percent complete as of the date of completion of the Raytheon Merger, since only the unperformed portion of the contract at such date represents the obligation of the Company. This will have the impact of reducing gross favorable and unfavorable EAC adjustments for these segments in the short-term, with the exception of EAC adjustments related to loss contracts. For additional information related to the Raytheon Merger, see “Note 2: Acquisitions, Dispositions, Goodwill and Other Intangible Assets.” In our Collins Aerospace and Pratt & Whitney businesses, we incur contract fulfillment costs for engineering and development of aerospace OEM products directly related to existing or anticipated contracts with customers. Such costs generate or enhance our ability to satisfy our performance obligations under these contracts. We capitalize these costs as contract fulfillment costs to the extent the costs are recoverable from the associated contract margin and subsequently amortize the costs as the related performance obligations are satisfied. In instances where intellectual property does not transfer to the customer, we generally defer the customer funding of product engineering and development and recognize revenue when the related performance obligations are satisfied. Capitalized contract fulfillment costs were $1,912 million and $1,519 million as of September 30, 2020 and December 31, 2019, respectively and are recognized in Other assets in our Condensed Consolidated Balance Sheet and are included in Other operating activities, net in our Condensed Consolidated Statement of Cash Flows. We regularly assess capitalized contract fulfillment costs for impairment. Costs to obtain contracts are not material. In view of the risks and costs associated with developing new engines, Pratt & Whitney has entered into certain collaboration arrangements in which sales, costs and risks are shared. Sales generated from engine programs, spare parts sales, and aftermarket business under collaboration arrangements, primarily at our Pratt & Whitney business, are recorded consistent with our revenue recognition policies in our Condensed Consolidated Financial Statements. Amounts attributable to our collaborators for their share of sales are recorded as cost of sales in our Consolidated Financial Statements based upon the terms and nature of the arrangement. Costs associated with engine programs under collaborative arrangements are expensed as incurred. Under these arrangements, collaborators contribute their program share of engine parts, incur their own production costs and make certain payments for shared or joint program costs. The reimbursement from collaborators of their share of program costs is recorded as a reduction of the related expense item at that time. As of September 30, 2020, the collaborators’ interests in all commercial engine programs ranged from 13% to 49%, inclusive of a portion of Pratt & Whitney’s interests held by other participants. Pratt & Whitney is the principal participant in all existing collaborative arrangements, with the exception of the Engine Alliance (EA), a joint venture with GE Aviation, which markets and manufactures the GP7000 engine for the Airbus A380 aircraft. There are no individually significant collaborative arrangements, and none of the collaborators individually exceed a 31% share in an individual program. In our Collins Aerospace and Pratt & Whitney businesses, we may offer customers incentives to purchase our products, which may result in payments made to those customers. In addition, we make participation payments to certain aerospace customers to secure certain contractual rights. To the extent these rights are incremental and are supported by the incremental cash flows obtained, they are capitalized as intangible assets. Otherwise, such payments are recorded as a reduction in sales. We classify the subsequent amortization of the capitalized acquired intangible assets from our customers as a reduction in sales.
Remaining Performance Obligations	Remaining Performance Obligations (RPO). RPO represent the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. Total RPO was $152.3 billion as of September 30, 2020. Of the total RPO as of September 30, 2020, we expect approximately 30% will be recognized as sales over the next 12 months. This percentage of RPO to be recognized as sales over the next 12 months depends on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the scope, severity and duration of the COVID-19 pandemic, actions to contain its spread or treat its impact, and governmental, business and individuals’ actions taken in response to the pandemic, which may result in customer delays or order cancellations.
Research and Development Expense, Policy	Research and Development. Company-sponsored research and development costs, including those costs related to the Company’s portion in connection with cost-sharing arrangements, are charged to expense as incurred and recovery on these cost-sharing arrangements is recorded as a reduction to research and development expense as earned. Customer-sponsored research and development projects performed under contracts with customers are accounted for as contract costs and reported as cost of sales on the related revenue generating contracts.
Foreign Currency Transactions and Translations Policy	Foreign Exchange. We conduct business in many different currencies and, accordingly, are subject to the inherent risks associated with foreign exchange rate movements. The financial position and results of operations of many of our foreign subsidiaries are measured using the local currency as the functional currency. Foreign currency denominated assets and liabilities are translated into U.S. Dollars at the exchange rates existing at the respective balance sheet dates, and income and expense items are translated at the average exchange rates during the respective periods. The aggregate effects of translating the balance sheets of these subsidiaries are deferred as a separate component of accumulated other comprehensive loss (AOCL) in shareowners’ equity.
Derivatives, Policy	Derivatives and Hedging Activity. From time to time, we use derivative instruments, including swaps, forward contracts and options, to help manage certain foreign currency, interest rate and commodity price exposures. Derivative instruments are viewed as risk management tools by us and are not used for trading or speculative purposes. By their nature, all financial instruments involve market and credit risks. We enter into derivative and other financial instruments with major investment grade financial institutions and have policies to monitor the credit risk of those counterparties. We limit counterparty exposure and concentration of risk by diversifying counterparties. While there can be no assurance, we do not anticipate any material non-performance by any of these counterparties. We enter into transactions that are subject to enforceable master netting arrangements or similar agreements with various counterparties. However, we have not elected to offset multiple contracts with a single counterparty and, as a result, the fair value of the derivative instruments in a loss position is not offset against the fair value of derivative instruments in a gain position. Derivatives used for hedging purposes may be designated and effective as a hedge of the identified risk exposure at the inception of the contract. All derivative instruments are recorded on the balance sheet at fair value. Derivatives used to hedge foreign currency denominated balance sheet items are reported directly in earnings along with offsetting transaction gains and losses on the items being hedged. Derivatives used to hedge forecasted cash flows associated with foreign currency commitments or forecasted commodity purchases may be accounted for as cash flow hedges, as deemed appropriate. Gains and losses on derivatives designated as cash flow hedges are recorded in other comprehensive income and reclassified to earnings as a component of product sales or expenses, as applicable, when the hedged transaction occurs. Gains and losses on derivatives designated as cash flow hedges are recorded in Other operating activities, net within the Condensed Consolidated Statement of Cash Flows. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded currently in earnings in the period it occurs. To the extent the hedge accounting criteria are not met, the foreign currency forward contracts are utilized as economic hedges and changes in the fair value of these contracts are recorded currently in earnings in the period in which they occur. Cash receipts or payments related to the settlement of derivatives not designated as hedging instruments are recorded as investing cash flows within the Condensed Consolidated Statement of Cash Flows. Additional information pertaining to foreign currency forward contracts and net investment hedging is included in “Note 12: Financial Instruments.”
Environmental Costs, Policy	Environmental . Environmental investigatory, remediation, operating and maintenance costs are accrued when it is probable that a liability has been incurred and the amount can be reasonably estimated. The most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site, including existing technology, current laws and regulations and prior remediation experience. Where no amount within a range of estimates is more likely, the minimum is accrued. For sites with multiple responsible parties, we consider our likely proportionate share of the anticipated remediation costs and the ability of the other parties to fulfill their obligations in establishing a provision for those costs. Liabilities with fixed or reliably determinable future cash payments are discounted. A portion of these costs is eligible for future recovery through the pricing of our products and services to the U.S. government. We regularly assess the probability of recovery of these costs, which requires us to make assumptions about the extent of cost recovery under our contracts and the amount of future contract activity with the U.S. government. We consider such recovery probable based on government contracting regulations and our history of receiving reimbursement for such costs, and accordingly have recorded the future recovery of these costs from the U.S. government within Other assets in the Condensed Consolidated Balance Sheet. Accrued environmental liabilities are not reduced by potential insurance reimbursements or potential recoveries from pursuing other parties. See “Note 17: Commitments and Contingencies” for additional details on the environmental remediation activities.
Pension and Other Postretirement Plans, Policy	Pension and Postretirement Obligations. U.S. GAAP requires balance sheet recognition of the overfunded or underfunded status of pension and postretirement benefit (PRB) plans. Funded status is measured at least annually in the fourth quarter and represents the difference between the plans’ projected benefit obligation (PBO) and the fair market value of the plans’ assets. Changes to our pension and PRB plans’ funded status can result from company actions, such as contributions or changes in plan provisions, or by gains and losses. Gains and losses are primarily a result of changes in discount rates, differences between actual and expected asset returns, and differences between actual and assumed demographic experience. These gains or losses are recorded in other comprehensive income, net of tax effects, until they are amortized as a component of net periodic benefit (income) cost. 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 equal to the fair value of assets adjusted to reflect the recognition, and subsequent amortization, of the difference between actual and expected asset return over a five-year period. The market-related value of assets is used to calculate the expected return on assets included in the net periodic benefit (income) cost. The company has elected to use the “corridor” approach in the amortization of gains and losses, which limits the expense recognition to the net outstanding gains and losses in excess of the greater of 10% of the PBO or 10% of the market-related value of assets. Gains and losses exceeding the corridor are amortized in net periodic benefit (income) cost over either the projected average remaining employee service period or the projected average remaining lifetime of inactive participants depending on the plan. Net periodic benefit (income) cost is split between operating profit and non-operating income, whereby only the service cost component is included in operating profit and the remaining components are included in Non-service pension (income) expense.
Extended Product Warranty, Policy	Product Performance Obligations. We extend performance and operating cost guarantees beyond our normal service and warranty policies for extended periods on some of our products, particularly commercial aircraft engines. Liability under such guarantees is based upon future product performance and durability. We accrue for such costs that are probable and can be reasonably estimated. In addition, we incur discretionary costs to service our products in connection with product performance issues. The costs associated with these product performance and operating cost guarantees require estimates over the full terms of the agreements, and require management to consider factors such as the extent of future maintenance requirements and the future cost of material and labor to perform the services. These cost estimates are largely based upon historical experience. See “Note 16: Guarantees” for further discussion.
New Accounting Pronouncements, Policy [Text Block]	Accounting Pronouncements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU and its related amendments (collectively, the Credit Loss Standard) modifies the impairment model to utilize an expected loss methodology in place of the incurred loss methodology for financial instruments, including trade receivables, contract assets and off-balance sheet credit exposures. The Credit Loss Standard requires consideration of a broader range of information to estimate expected credit losses, including historical information, current economic conditions and a reasonable forecast period. This ASU requires that the statement of operations reflect estimates of expected credit losses for newly recognized financial assets as well as changes in the estimate of expected credit losses that have taken place during the period, which may result in earlier recognition of certain losses. We adopted this standard effective January 1, 2020 utilizing a modified retrospective approach. A cumulative-effect non-cash adjustment to retained earnings as of January 1, 2020 was recorded in the amount of $59 million. The adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Financial Statements. We are exposed to credit losses primarily through our sales of products and services to commercial customers which are recorded as trade receivables, contract assets, long-term receivables, and notes and lease receivables on the Condensed Consolidated Balance Sheet. We do not have exposure for credit losses related to sales of products and services to our government customers. Our method for developing our allowance for credit losses involves making informed judgments regarding whether an adjustment is necessary to our historical loss experiences to reflect our expectations around current economic conditions and reasonable and supportable forecast periods, where applicable. We utilize current economic market data as well as other internal and external information available to us to inform our decision making. In certain circumstances we may be able to develop reasonable and supportable forecasts over the contractual term of the financial asset or off-balance sheet exposure. For periods beyond which we are able to make or obtain reasonable and supportable forecasts, we revert to historical loss experience and information. We determine credit ratings for each customer in our portfolio based upon public information and information obtained directly from our customers. We conduct a review of customer credit ratings, published historical credit default rates for different rating categories, and multiple third-party aircraft value publications as a basis to validate the reasonableness of the allowance for credit losses on these balances quarterly or when events and circumstances warrant. In addition to credit quality indicators, factors considered in our evaluation of assessing collectability and risk include: underlying value of any collateral or security interests, significant past due balances, historical losses, and existing economic conditions, including geographic and political risk. A credit limit is established for each customer based on the outcome of this review. Customer credit ratings range from customers with an extremely strong capacity to meet financial obligations, to customers whose uncollateralized receivable is in default. We may require collateral or prepayment to mitigate credit risk. To estimate expected credit losses of financial assets with similar risk characteristics, we determine an asset is impaired when, based on historical experience, current information and a reasonable forecast period, there is risk that we will be unable to collect amounts due according to the contractual terms of the agreement. We monitor our ongoing credit exposure through reviews of customer balances against contract terms and due dates, current economic conditions, and dispute resolution. Estimated credit losses are written off in the period in which the financial asset is no longer collectible. We can also be exposed to credit losses from off-balance sheet exposures, such as certain financial guarantees and financing commitments. We have assessed these potential exposures and concluded that there are no associated credit losses as of September 30, 2020. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this update remove certain exceptions of Topic 740 including: exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or gain from other items; exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. There are also additional areas of guidance in regards to: franchise and other taxes partially based on income and the interim recognition of enactment of tax laws and rate changes. The provisions of this ASU are effective for years beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the impact of this ASU on our Consolidated Financial Statements. Other new pronouncements adopted and issued but not effective until after September 30, 2020 did not and are not expected to have a material impact on our financial position, results of operations or liquidity.
