Accounting Policies [Abstract]
Significant Accounting Policies and Recent Accounting Standards	Note A — Significant Accounting Policies and Recent Accounting Standards Basis of Presentation The accompanying Condensed Consolidated Financial Statements (Unaudited) include the accounts of L3Harris Technologies, Inc. and its consolidated subsidiaries. As used in these Notes to Condensed Consolidated Financial Statements (Unaudited) (these “Notes”), the terms “L3Harris,” “Company,” “we,” “our” and “us” refer to L3Harris Technologies, Inc. and its consolidated subsidiaries. Intracompany transactions and accounts have been eliminated in consolidation. The accompanying Condensed Consolidated Financial Statements (Unaudited) have been prepared by L3Harris, without an audit, in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, such interim financial statements do not include all information and footnotes necessary for a complete presentation of financial condition, results of operations, cash flows and equity in conformity with GAAP for annual financial statements. In the opinion of management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of our financial condition, results of operations, cash flows and equity for the periods presented therein. The results for the quarter and three quarters ended October 2, 2020 are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. The balance sheet at January 3, 2020 has been derived from our audited financial statements, but does not include all of the information and footnotes required by GAAP for annual financial statements. We provide complete, audited financial statements in our Transition Report on Form 10-KT for the fiscal transition period from June 29, 2019 to January 3, 2020 (our “Fiscal Transition Period Form 10-KT”), which includes information and footnotes required by the rules and regulations of the SEC. The information included in this Quarterly Report on Form 10-Q (this “Report”) should be read in conjunction with the Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements included in our Fiscal Transition Period Form 10-KT. Amounts contained in this Report may not always add to totals due to rounding. L3Harris Merger See Note B — Business Combination in these Notes for information related to the business combination in which Harris Corporation (“Harris”) and L3 Technologies, Inc. (“L3”) combined their respective businesses in an all-stock merger that resulted in our combined Company, L3Harris Technologies, Inc. Due to the L3Harris Merger (as defined in Note B — Business Combination in these Notes), the three quarters ended October 2, 2020 reflect the results of the combined Company, while the three quarters ended September 27, 2019 reflect the results of only Harris operating businesses for the two quarters ended June 28, 2019 and the results of the combined Company for the quarter ended September 27, 2019. Organizational Structure We implemented a new organizational structure effective on June 29, 2019, which resulted in changes to our operating segments, which are also reportable segments and referred to as our business segments. During the quarter ended April 3, 2020, we further adjusted our segment reporting to better align our businesses and transferred two businesses between our Integrated Mission Systems and Space and Airborne Systems segments. The historical results, discussion and presentation of our business segments as set forth in the accompanying Condensed Consolidated Financial Statements (Unaudited) and these Notes reflect the impact of these changes for all periods presented in order to present segment information on a comparable basis. There is no impact on our previously reported consolidated statements of income, balance sheets, statements of cash flows or statements of equity resulting from these changes. Divestitures See Note C — Business Divestitures and Assets Sales in these Notes for information regarding the following and other divestitures by us in 2019 and 2020: the divestiture of the Harris Night Vision business completed on September 13, 2019; the divestiture of the Security & Detection Systems and MacDonald Humfrey Automation solutions business completed on May 4, 2020; the divestiture of the Applied Kilovolts and Analytical Instrumentation business completed on May 15, 2020; and the divestiture of the EOTech business completed on July 31, 2020. Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying Condensed Consolidated Financial Statements (Unaudited) and these Notes and related disclosures. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying Condensed Consolidated Financial Statements (Unaudited) and these Notes. Materially different results can occur as circumstances change and additional information becomes known. Significant Accounting Policies Update There have been no material changes to our significant accounting policies described in our Fiscal Transition Period Form 10-KT, except as described in “Adoption of New Accounting Standards” below. Adoption of New Accounting Standards Effective January 3, 2020, we adopted Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments on a modified retrospective basis . The new standard replaces the existing impairment model, under which impairment of financial instruments, including accounts receivable and contract assets, is recognized when it becomes probable a loss has been incurred, with a model that requires recognition of expected credit losses over the estimated life of an asset at inception and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Adopting this standard did not have a material impact on our financial condition, results of operations, cash flows or equity.

Business Combination

Business Combinations [Abstract]
Business Combination	Note B — Business Combination On October 12, 2018, Harris Corporation, a Delaware corporation, entered into an Agreement and Plan of Merger (the “Merger Agreement”) with L3 Technologies, Inc., a Delaware corporation, and Leopard Merger Sub Inc., a Delaware corporation and a newly formed, direct wholly owned subsidiary of Harris (“Merger Sub”), pursuant to which Harris and L3 agreed to combine their respective businesses in an all-stock merger, at the closing of which Merger Sub would merge with and into L3, with L3 continuing as the surviving corporation and a direct wholly owned subsidiary of Harris (the “L3Harris Merger”). The closing of the L3Harris Merger occurred on June 29, 2019 (the “Closing Date”), the day after Harris’ fiscal 2019 ended and the first day of the fiscal transition period ended January 3, 2020 (the “Fiscal Transition Period”). Upon completion of the L3Harris Merger, Harris was renamed “L3Harris Technologies, Inc.” and each share of L3 common stock converted into the right to receive 1.30 shares (“Exchange Ratio”) of L3Harris common stock. Shares of L3Harris common stock, which previously traded under ticker symbol “HRS” on the New York Stock Exchange prior to completion of the L3Harris Merger, are traded under ticker symbol “LHX” following completion of the L3Harris Merger. L3Harris was owned on a fully diluted basis approximately 54 percent by Harris shareholders and 46 percent by L3 shareholders immediately following the completion of the L3Harris Merger. L3 was a prime contractor in intelligence, surveillance and reconnaissance (“ISR”) systems, aircraft sustainment (including modifications and fleet management of special mission aircraft), simulation and training, night vision and image intensification equipment, and security and detection systems. L3 also was a leading provider of a broad range of communication, electronic and sensor systems used on military, homeland security and commercial platforms. L3 employed approximately 31,000 employees and its customers included the U.S. Department of Defense and its prime contractors, the U.S. Intelligence Community, the U.S. Department of Homeland Security, foreign governments and domestic and foreign commercial customers. In connection with completion of the L3Harris Merger, we issued to L3 shareholders 104 million shares of L3Harris common stock, the trading price of which was $189.13 per share as of the Closing Date. In addition, we issued L3Harris share-based awards in replacement of certain outstanding L3 share-based awards held by employees. We accounted for the L3Harris Merger under the acquisition method of accounting, which required us to measure identifiable assets acquired, liabilities assumed and any noncontrolling interests in the acquiree at their fair values as of the Closing Date, with the excess of the consideration transferred over those fair values recorded as goodwill. Our calculation of consideration transferred is summarized below: (In millions, except exchange ratio and per share amounts) June 29, 2019 Outstanding shares of L3 common stock as of June 28, 2019 79.63 L3 restricted stock unit awards settled in shares of L3Harris common stock 0.41 L3 performance unit awards settled in shares of L3Harris common stock 0.04 80.08 Exchange Ratio 1.30 Shares of L3Harris common stock issued for L3 outstanding common stock 104.10 Price per share of L3Harris common stock as of June 28, 2019 $ 189.13 Fair value of L3Harris common stock issued for L3 outstanding common stock $ 19,689 Fair value of replacement restricted stock units attributable to merger consideration 10 Fair value of L3Harris stock options issued to replace L3 outstanding stock options 101 Withholding tax liability incurred for converted L3 share-based awards 45 Fair value of replacement award consideration 156 Fair value of total consideration 19,845 Less cash acquired (1,195) Total net consideration transferred $ 18,650 Our preliminary fair value estimates and assumptions to measure the assets acquired, liabilities assumed and noncontrolling interests in L3 were subject to change as we obtained additional information during the measurement period. We completed our accounting for the L3Harris Merger during the quarter ended July 3, 2020. The following table summarizes the fair value amounts recognized as of the Closing Date for each major class of asset acquired or liability assumed and noncontrolling interests, as well as adjustments made during the measurement period: (In millions) Preliminary Fair Value as of September 27, 2019 Measurement Period Adjustments Adjusted Fair Value as of July 3, 2020 Receivables $ 849 $ (20) $ 829 Contract assets 1,708 (57) 1,651 Inventories 1,056 (73) 983 Other current assets 517 (16) 501 Property, plant and equipment 1,176 43 1,219 Operating lease right-of-use assets 704 108 812 Goodwill 15,423 (841) 14,582 Other intangible assets 6,768 1,690 8,458 Other non-current assets 327 (13) 314 Total assets acquired $ 28,528 $ 821 $ 29,349 Accounts payable $ 898 $ (13) $ 885 Contract liabilities 722 4 726 Other current liabilities 772 301 1,073 Operating lease liabilities 715 45 760 Defined benefit plans 1,411 — 1,411 Long-term debt, net 3,548 — 3,548 Other long-term liabilities 1,661 480 2,141 Total liabilities assumed 9,727 817 10,544 Net assets acquired 18,801 4 18,805 Noncontrolling interests (151) (4) (155) Total net consideration transferred $ 18,650 $ — $ 18,650 Additionally, we acquired certain off-market customer contracts in connection with the L3Harris Merger, and we have recorded liabilities as well as separate identifiable intangible assets for the acquisition-date fair value of the off-market components of these customer contracts. In aggregate, the acquisition-date fair value of the off-market components was a net liability of $139 million. We measured the fair value of these components as the present value of the amount by which the terms of the contract with the customer deviated from the terms that a market participant could have achieved at the Closing Date. The off-market components of these contracts will be recognized as an increase to, or reduction of, revenue as we incur costs to satisfy the associated performance obligations. We recognized $11 million and $51 million of revenue in the quarter and three quarters ended October 2, 2020, respectively, for amortization of net off-market contract liabilities (including, for three quarters ended October 2, 2020, the cumulative effect of amortization that would have been recognized in the Fiscal Transition Period). We recognized $13 million for amortization of net off-market contract liabilities in the Fiscal Transition Period. Future estimated revenue from the amortization of net off-market contract liabilities (based on the estimated pattern of cash flows to be incurred to satisfy associated performance obligations) is as follows: $7 million in the remainder of 2020, $20 million in 2021, $15 million in 2022, $10 million in 2023 and $23 million thereafter. The goodwill resulting from the L3Harris Merger is primarily associated with L3’s market presence and leading positions, growth opportunities in the markets in which L3 businesses operate, experienced work force and established operating infrastructures. Most of the goodwill related to the L3Harris Merger is nondeductible for tax purposes. See Note K — Goodwill and Other Intangible Assets in these Notes for more information regarding the allocation of goodwill by business segment. The following table provides further detail of the fair value and weighted-average amortization period of identifiable intangible assets acquired by major intangible asset class: Weighted Average Amortization Period Total (In years) (In millions) Identifiable intangible assets acquired: Customer relationships (Government) 14 $ 5,082 Customer relationships (Commercial) 15 860 Contract backlog 3 19 Trade names — divisions 9 123 Developed technologies 7 550 Total identifiable intangible assets subject to amortization 13 6,634 Trade names — corporate indefinite 1,803 In-process research and development n/a 21 Total identifiable intangible assets $ 8,458 L3Harris Merger-related charges were as follows: Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Equity award acceleration charges, recognized upon change in control $ — $ (61) $ — $ (61) Transaction costs, recognized as incurred — (74) — (96) Additional cost of sales related to the fair value step-up in inventory sold — (92) (31) (92) Restructuring charges — (111) (7) (111) Integration costs, recognized as incurred (27) (35) (95) (65) Total L3Harris Merger-related charges $ (27) $ (373) $ (133) $ (425) Because the L3Harris Merger benefited the entire Company as opposed to any individual business segment, the above costs were not allocated to any business segment. All of the above costs were recorded in the “Engineering, selling and administrative expenses” line item in our Condensed Consolidated Statement of Income (Unaudited), except for the additional cost of sales related to the fair value step-up in inventory sold. Pro Forma Results The following unaudited consolidated pro forma results of operations for the three quarters ended September 27, 2019 combines reported results for the quarter ended September 27, 2019 with the pro forma results for the two quarters ended June 28, 2019. The pro forma results for the two quarters ended June 28, 2019 were prepared on a pro forma basis, as if the L3Harris Merger had been completed as of June 30, 2018, the first day of Harris’ fiscal 2019, after including any post-acquisition adjustments directly attributable to the acquisition, such as the sale of Harris’ Night Vision business, and after including the impact of pro forma adjustments such as amortization of identifiable intangible assets as well as the related income tax effects. This pro forma presentation does not include any impact of transaction synergies. The pro forma results are not necessarily indicative of our results of operations that actually would have been obtained had the combination of Harris and L3 been completed on the assumed date or for the period presented, or which may be realized in the future.

Business Divestitures and Asset

Business Divestitures and Assets Sales	9 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
Business Divestitures and Assets Sales	Note C — Business Divestitures and Assets Sales EOTech business. On July 31, 2020, we completed the divestiture of our EOTech business for $42 million (net cash proceeds of $40 million after selling costs and estimated purchase price adjustments), subject to final customary purchase price adjustments as set forth in the definitive sale agreement, and recognized a pre-tax gain of $2 million, which is included in the “Business divestiture-related (losses) gains” line item in our Condensed Consolidated Statement of Income (Unaudited) for the quarter and three quarters ended October 2, 2020. The EOTech business manufactures holographic sighting systems, magnified field optics and accessories for military, law enforcement and commercial markets around the world. The operating results of the EOTech business through the date of divestiture are reported as part of our Communication Systems segment. Income before income taxes of the EOTech business through the date of divestiture was not material for the quarter or three quarters ended October 2, 2020 or the quarter or three quarters ended September 27, 2019. In connection with the preparation of our financial statements for the quarter ended April 3, 2020, we tested goodwill assigned to the EOTech business disposal group and goodwill assigned to the retained businesses of the reporting unit for impairment and concluded that no goodwill impairment existed at the time the held for sale criteria were met. Applied Kilovolts and Analytical Instrumentation business. On May 15, 2020, we completed the divestiture of our Applied Kilovolts and Analytical Instrumentation business for net cash proceeds of $12 million, after selling costs and estimated purchase price adjustments, subject to final customary purchase price adjustments as set forth in the definitive sale agreement. The operating results of the Applied Kilovolts and Analytical Instrumentation business through the date of divestiture are reported as part of our Space and Airborne Systems segment. Income before income taxes of the Applied Kilovolts and Analytical Instrumentation business through the date of divestiture was not material for the three quarters ended October 2, 2020 or the quarter or three quarters ended September 27, 2019. In connection with the preparation of our financial statements for the quarter ended April 3, 2020, we tested goodwill assigned to the Applied Kilovolts and Analytical Instrumentation business disposal group and goodwill assigned to the retained businesses of the reporting unit for impairment and concluded that goodwill related to the disposal group was impaired. As a result, we recorded a non-cash impairment charge of $5 million, which is included in the “Impairment of goodwill and other assets” line item in our Condensed Consolidated Statement of Income (Unaudited) for the three quarters ended October 2, 2020. Airport security and automation business. On May 4, 2020, we completed the divestiture of the Security & Detection Systems and MacDonald Humfrey Automation solutions business (“airport security and automation business”) to Leidos, Inc. for $1 billion (net cash proceeds of $950 million after selling costs and estimated purchase price adjustments), subject to final customary purchase price adjustments as set forth in the definitive sale agreement, and recognized a pre-tax loss of $26 million during the quarter ended July 3, 2020. During the quarter ended October 2, 2020, we recognized a $2 million adjustment related to selling costs, which increased the loss initially recognized. These charges are included in the “Business divestiture-related (losses) gains” line item in our Condensed Consolidated Statement of Income (Unaudited) for the quarter and three quarters ended October 2, 2020. The airport security and automation business provides solutions used by the aviation and transportation industries, regulatory and customs authorities, government and law enforcement agencies and commercial and other high-security facilities. The operating results of the airport security and automation business through the date of divestiture are reported as part of our Aviation Systems segment. Income before income taxes of the airport security and automation business through the date of divestiture was not material for the three quarters ended October 2, 2020 or the quarter or three quarters ended September 27, 2019. Because the then-pending divestiture of the airport security and automation business would represent the disposal of a portion of a reporting unit within our Aviation Systems segment, we assigned $531 million of goodwill to the airport security and automation business disposal group on a relative fair value basis during the quarter ended April 3, 2020, when the held for sale criteria were met. In connection with the preparation of our financial statements for the quarter ended April 3, 2020, we tested goodwill assigned to the disposal group and goodwill assigned to the retained businesses of the reporting unit for impairment and concluded that no goodwill impairment existed at the time the held for sale criteria were met in late January 2020. However, indicators of potential impairment of goodwill related to the retained businesses of the reporting unit were present at April 3, 2020 and July 3, 2020 due to the downturn in the commercial aviation market that resulted from the novel COVID-19 strain of coronavirus (“COVID-19”) pandemic and its impact on global air traffic and customer demand. See Note K — Goodwill and Other Intangible Assets in these Notes for additional information regarding goodwill impairment. Other AS Disposal Group. During the quarter ended July 3, 2020, we determined the criteria to be classified as held for sale were met with respect to another business within our Aviation Systems segment (“other AS disposal group”); consequently, the assets and liabilities of the other AS disposal group are classified as held for sale in our Condensed Consolidated Balance Sheet (Unaudited) as of October 2, 2020. Income before income taxes of the other AS disposal group was not material for the quarter or three quarters ended October 2, 2020 or the quarter or three quarters ended September 27, 2019. Because the potential divestiture of the other AS disposal group would represent the disposal of a portion of a reporting unit within our Aviation Systems segment, we assigned $14 million of goodwill to the other AS disposal group on a relative fair value basis during the quarter ended July 3, 2020, when the held for sale criteria were met. In connection with the preparation of our financial statements for the quarter ended July 3, 2020, we recognized a $28 million loss to reduce the assets of the other AS disposal group to fair value, which included a non-cash goodwill impairment charge of $14 million (based on the excess of the carrying value of the business over estimated net cash proceeds, after estimated purchase price adjustments) and a $14 million non-cash remeasurement loss to reduce the remaining assets to fair value. In connection with the preparation of our financial statements for the quarter ended October 2, 2020, we recognized an additional non-cash remeasurement loss of $10 million to reduce the assets of the other AS disposal group to fair value. These charges are included in the “Impairment of goodwill and other assets” and “Business divestiture-related (losses) gains” line items in our Condensed Consolidated Statement of Income (Unaudited) for the quarter and three quarters ended October 2, 2020. The carrying amounts of assets and liabilities of the other AS disposal group that were classified as held for sale in our Condensed Consolidated Balance Sheet (Unaudited) at October 2, 2020 were $34 million and $15 million, respectively. We expect to complete the sale of the other AS disposal group by the end of the first quarter of 2021. Harris Night Vision. On September 13, 2019, we completed the sale of the Harris Night Vision business, a global supplier of high-performance, vision-enhancing products for U.S. and allied military and security forces and commercial customers, for $350 million (net cash proceeds of $343 million after selling costs and purchase price adjustments), subject to final customary purchase price adjustments pursuant to a definitive agreement we entered into on April 4, 2019 as part of the regulatory process in connection with the L3Harris Merger, and recognized a pre-tax gain of $229 million in the “Business divestiture-related (losses) gains” line item in our Condensed Consolidated Statement of Income (Unaudited) during the quarter ended September 27, 2019. During the quarter ended July 3, 2020, we finalized the purchase price adjustments and recognized a $12 million non-cash adjustment related to working capital, which decreased the gain initially recognized and is included in the “Business divestiture-related (losses) gains” line item in our Condensed Consolidated Statement of Income (Unaudited) for the three quarters ended October 2, 2020. Through fiscal 2019, the Harris Night Vision business was reported as part of our former Communication Systems segment. As a result of the then-pending divestiture, the Harris Night Vision business was not included in any of our new business segments and, consequently, the operating results of the business are included in “Other non-reportable business segments” for the quarter and three quarters ended September 27, 2019 in this Report. See Note V — Business Segment Information in these Notes for additional information. For purposes of allocating goodwill to the disposal groups above, we determined the fair value of each disposal group based on the respective negotiated selling price (or estimated net cash proceeds, in the case of no negotiated selling price), and the fair value of the retained businesses of the respective reporting unit based on a combination of market-based valuation techniques, utilizing quoted market prices and comparable publicly reported transactions, and projected discounted cash flows. These fair value determinations are categorized as Level 3 in the fair value hierarchy due to their use of internal projections and unobservable measurement inputs. See Note 1: “Significant Accounting Policies” in the Notes to Consolidated Financial Statements in our Fiscal Transition Period Form 10-KT for additional information regarding the fair value hierarchy. Stormscope . On August 30, 2019, we completed the sale of the Stormscope product line for $20 million in cash and recorded a pre-tax gain of $12 million in the “Engineering, selling and administrative expenses” line item of our Condensed Consolidated Statement of Income (Unaudited) during the quarter ended September 27, 2019.

Share-based Payment Arrangement [Abstract]
Stock Options and Other Share-Based Compensation	Note D — Stock Options and Other Share-Based Compensation As of October 2, 2020, we had options or other share-based compensation outstanding under two Harris shareholder-approved stock incentive plans, the Harris Corporation 2005 Equity Incentive Plan (As Amended and Restated Effective August 27, 2010) and the Harris Corporation 2015 Equity Incentive Plan (As Amended and Restated Effective as of August 28, 2020), as well as under employee stock incentive plans of L3 assumed by L3Harris (collectively, “L3Harris SIPs”). The compensation cost related to our share-based awards that was charged against income was $31 million and $71 million, respectively, for the quarter and three quarters ended October 2, 2020, and $95 million and $124 million, respectively, for the quarter and three quarters ended September 27, 2019, including acceleration expense recognized in connection with the L3Harris Merger. The aggregate number of shares of our common stock that we issued under the terms of L3Harris SIPs, net of shares withheld for tax purposes, was not material for the quarter ended October 2, 2020 and was 0.5 million for the three quarters ended October 2, 2020, and 2.8 million and 3.4 million for the quarter and three quarters ended September 27, 2019, respectively, including shares issued as merger consideration to settle pre-merger L3 share-based awards. Awards granted to participants under L3Harris SIPs during the quarter ended October 2, 2020 were not material. Awards granted to participants under L3Harris SIPs during the three quarters ended October 2, 2020 consisted of 0.3 million restricted stock units, 0.6 million stock options and 0.2 million performance stock units. The fair value as of the grant date of each stock option award was determined using the Black-Scholes-Merton option-pricing model and the following assumptions: expected dividend yield of 1.55 percent; expected volatility of 22.74 percent; risk-free interest rates averaging 0.89 percent; and expected term of 5.04 years. The fair value as of the grant date of each restricted stock unit award was based on the closing price of our common stock on the grant date. The fair value as of the grant date of each performance stock unit award was determined based on the fair value from a multifactor Monte Carlo valuation model that simulates our stock price and total shareholder return (“TSR”) relative to companies in our TSR peer group.

Restructuring and Related Activities [Abstract]
Restructuring and Other Exit Costs	Note E — Restructuring and Other Exit Costs We record charges for restructuring and other exit activities related to sales or terminations of product lines, closures or relocations of business activities, changes in management structure and fundamental reorganizations that affect the nature and focus of operations. Such charges include termination benefits, contract termination costs and costs to consolidate facilities or relocate employees. We record these charges at their fair value when incurred. In cases where employees are required to render service until they are terminated in order to receive the termination benefits and will be retained beyond the minimum retention period, we record the expense ratably over the future service period. These charges are included as a component of the “Engineering, selling and administrative expenses” line item in our Condensed Consolidated Statement of Income (Unaudited). L3Harris Merger-Related Restructuring Costs. We recorded restructuring charges of $7 million during the quarter ended July 3, 2020 and $111 million during the quarter ended September 27, 2019 in connection with the L3Harris Merger. At October 2, 2020, we had liabilities of $24 million associated with these L3Harris Merger-related restructuring actions, of which substantially all will be paid in the next twelve months. COVID-19-Related Restructuring Costs. During the quarter and three quarters ended October 2, 2020, we recorded $2 million and $16 million, respectively, of restructuring charges, including workforce reductions and other exit costs within our Aviation Systems segment associated with the COVID-19-related downturn in our Commercial Aviation Solutions sector and its impact on global air traffic and customer operations. In addition, during the quarter ended July 3, 2020, we recorded $1 million of restructuring charges for workforce reductions in our Communication Systems segment associated with the COVID-19 impact to local and state government customers of our Public Safety sector. At October 2, 2020, we had liabilities of $10 million associated with COVID-19-related restructuring actions, of which substantially all will be paid in the next twelve months. Other Restructuring and Exit Costs. Prior to the L3Harris Merger, we had liabilities for lease obligations associated with exited facilities with remaining terms of three years or less, of which $6 million remained outstanding at October 2, 2020. Our liabilities for restructuring and other exit costs are included in the “Other accrued items” and “Other long-term liabilities” line items in our Condensed Consolidated Balance Sheet (Unaudited). Changes to our liabilities for restructuring and other exit costs during the three quarters ended October 2, 2020 were as follows: (In millions) Employee severance-related costs Facilities consolidation and other exit costs Total Balance at January 3, 2020 $ 58 $ 7 $ 65 Additional provisions 24 — 24 Payments (49) (1) (50) Other, including foreign currency translation adjustments 1 — 1 Total changes (24) (1) (25) Balance at October 2, 2020 $ 34 $ 6 $ 40

Revenue from Contract with Customer [Abstract]
Contract Assets and Contract Liabilities	Note H — Contract Assets and Contract Liabilities Contract assets include unbilled amounts typically resulting from revenue recognized exceeding amounts billed to customers for contracts utilizing the percentage of completion (“POC”) cost-to-cost revenue recognition method. We bill customers as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals, upon achievement of contractual milestones or upon deliveries and, in certain arrangements, the customer may withhold payment of a small portion of the contract price until contract completion. Contract liabilities include advance payments and billings in excess of revenue recognized, including deferred revenue associated with extended product warranties. Contract assets and liabilities are reported on a contract-by-contract basis at the end of each reporting period. Contract assets and liabilities in the three quarters ended October 2, 2020 were impacted primarily by divestitures, reclassifications to assets and liabilities of disposal group held for sale, accelerated progress payments due to the U.S. Government's increase in the progress payment rate from 80 percent to 90 percent and the timing of contractual billing milestones. See Note C — Business Divestitures and Assets Sales in these Notes for additional information regarding assets and liabilities held for sale. Contract assets and contract liabilities are summarized below: (In millions) October 2, 2020 January 3, 2020 Contract assets $ 2,416 $ 2,459 Contract liabilities, current (1,089) (1,214) Contract liabilities, non-current (1) (76) (87) Net contract assets $ 1,251 $ 1,158 _______________ (1) The non-current portion of contract liabilities is included as a component of the “Other long-term liabilities” line item in our Condensed Consolidated Balance Sheet (Unaudited). The components of contract assets are summarized below: (In millions) October 2, 2020 January 3, 2020 Unbilled contract receivables, gross $ 4,166 $ 3,690 Progress payments and advances (1,750) (1,231) Contract assets $ 2,416 $ 2,459 Impairment losses related to our contract assets were not material for the quarter or three quarters ended October 2, 2020 or the quarter or three quarters ended September 27, 2019. For the quarter and three quarters ended October 2, 2020, we recognized as revenue $0.1 billion and $0.8 billion, respectively, of contract liabilities that were outstanding at January 3, 2020. For the quarter ended September 27, 2019, we recognized as revenue $0.6 billion of contract liabilities that were outstanding at June 29, 2019. Because of the L3Harris Merger and our change in fiscal year-end from June to December, revenue recognized in the three quarters ended September 27, 2019 from contract liabilities that were outstanding at the end of the prior year is not comparable. Note U — Backlog Backlog, which is the equivalent of our remaining performance obligations, represents the future revenue we expect to recognize as we perform on our current contracts. Backlog comprises both funded backlog (i.e., firm orders for which funding is authorized and appropriated) and unfunded backlog. Backlog excludes unexercised contract options and potential orders under ordering-type contracts, such as indefinite delivery, indefinite quantity contracts. At October 2, 2020, our ending backlog was $20.8 billion. We expect to recognize approximately 65 percent of the revenue associated with this backlog by the end of 2021 and approximately 80 percent by the end of 2022, with the remainder to be recognized thereafter. At January 3, 2020, our ending backlog was $20.6 billion, including $380 million of backlog associated with the airport security and automation business, which was divested during the quarter ended July 3, 2020.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Note K — Goodwill and Other Intangible Assets Goodwill As discussed in Note V — Business Segment Information in these Notes, after the completion of the L3Harris Merger, we adjusted our segment reporting to reflect our new organizational structure effective for the quarter ended September 27, 2019. Immediately before and after our goodwill assignments, we completed an assessment of any potential goodwill impairment under our former and new segment reporting structure and determined that no impairment existed. The assignment of goodwill by business segment, and changes in the carrying amount of goodwill, by business segment, for the three quarters ended October 2, 2020, were as follows: (In millions) Integrated Mission Systems Space and Airborne Systems Communication Systems Aviation Systems Total Balance at January 3, 2020 $ 5,768 $ 5,131 $ 4,243 $ 4,859 $ 20,001 Goodwill decrease from divestitures (1) — (2) (9) (530) (541) Impairment of goodwill — (5) — (364) (369) Currency translation adjustments (3) (4) (2) 1 (8) Other (including adjustments to previously estimated fair value of assets acquired and liabilities assumed) (2) 740 112 (82) (861) (91) Balance at October 2, 2020 $ 6,505 $ 5,232 $ 4,150 $ 3,105 $ 18,992 _______________ (1) During the three quarters ended October 2, 2020, we completed the divestiture of three businesses (airport security and automation business, Applied Kilovolts and Analytical Instrumentation business and EOTech business) and derecognized $541 million of goodwill as the part of determining the gain or loss on these divestitures. See Note C — Business Divestitures and Assets Sales in these Notes for additional information. (2) See Note B — Business Combination in these Notes for additional information regarding adjustments to previously estimated fair values of assets acquired and liabilities assumed. Commercial Aviation Solutions Impairment. Indications of potential impairment of goodwill related to our Commercial Aviation Solutions reporting unit (which is part of our Aviation Systems segment) were present at April 3, 2020 and July 3, 2020 due to COVID-19 and its impact on global air traffic and customer operations, which resulted in a decrease in the fiscal 2020 outlook for the reporting unit. Although our cash flow projections for the Commercial Aviation Solutions reporting unit did not change significantly compared with the projected cash flows as of April 3, 2020, we determined it was more-likely-than-not that the fair value of our Commercial Aviation Solutions reporting unit was less than its carrying amount as of July 3, 2020 due to the amount by which the fair value of the Commercial Aviation Solutions reporting unit exceeded its carrying amount as of April 3, 2020 and heightened uncertainty regarding the timing of expected recovery for the overall commercial aviation market. Consequently, in connection with the preparation of our financial statements for the quarters ended April 3, 2020 and July 3, 2020, we performed quantitative impairment tests on an interim basis. To test for potential impairment of goodwill related to our Commercial Aviation Solutions reporting unit, we prepared an estimate of the fair value of the reporting unit based on a combination of market-based valuation techniques, utilizing quoted market prices and comparable publicly reported transactions, and projected discounted cash flows. As a result of these impairment tests, we concluded that goodwill related to our Commercial Aviation Solutions reporting unit was impaired as of April 3, 2020 and July 3, 2020, and we recorded non-cash impairment charges of $296 million (including $28 million attributable to noncontrolling interests) during the quarter ended April 3, 2020 and $54 million (including $8 million attributable to noncontrolling interests) during the quarter ended July 3, 2020. These charges are included in the “Impairment of goodwill and other assets” line item in our Condensed Consolidated Statement of Income (Unaudited) for the three quarters ended October 2, 2020 and are primarily not deductible for tax purposes. Other AS Disposal Group Impairment. During the quarter ended July 3, 2020, we determined the criteria to be classified as held for sale were met with respect to the other AS disposal group within our Aviation Systems segment and assigned $14 million of goodwill to the disposal group on a relative fair value basis. In connection with the preparation of our financial statements for the quarter ended July 3, 2020, we concluded that goodwill related to the other AS disposal group was impaired and recorded a non-cash impairment charge of $14 million, which is included in the “Impairment of goodwill and other assets” line item in our Condensed Consolidated Statement of Income (Unaudited) for the three quarters ended October 2, 2020. Identifiable Intangible Assets The most significant identifiable intangible asset that is separately recognized for our business combinations is customer relationships. Our customer relationships are established through written customer contracts (revenue arrangements). The fair value for a customer relationship is determined, as of the date of acquisition of such relationship, based on estimates and judgments regarding expectations for the estimated future after-tax earnings and cash flows arising from the follow-on sales expected from the customer relationship over its estimated life, including the probability of expected future contract renewals and sales, less a contributory asset charge, all of which is discounted to present value. We assess the recoverability of the carrying value of our finite-lived identifiable intangible assets whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. We assess the recoverability of the carrying value of indefinite-lived identifiable intangible assets annually, or under certain circumstances more frequently, such as when events and circumstances indicate there may be an impairment. In conjunction with, and in advance of, the interim tests of goodwill related to our Commercial Aviation Solutions reporting unit, we also performed recoverability tests of the long-lived assets of our Commercial Aviation Solutions reporting unit, including identifiable intangible assets and property, plant and equipment. To test these long-lived assets for recoverability, we compared the estimated future cash flows (on an undiscounted basis) to be generated from the use and hypothetical eventual disposition of the asset group to its carrying value and concluded that the long-lived assets of our Commercial Aviation Solutions reporting unit were not impaired at April 3, 2020 or July 3, 2020.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note R — Fair Value Measurements Fair value is defined as the price that would be received for an asset or the price that would be paid to transfer a liability in the principal market or most advantageous market in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed using the best information available in the circumstances. In certain instances, fair value is estimated using quoted market prices obtained from external pricing services. In obtaining such data from the external pricing services, we have evaluated the methodologies used to develop the estimate of fair value in order to assess whether such valuations are representative of fair value, including net asset value (“NAV”). Additionally, in certain circumstances, the NAV reported by an asset manager may be adjusted when sufficient evidence indicates NAV is not representative of fair value. The following table presents assets and liabilities measured at fair value on a recurring basis (at least annually) at October 2, 2020 and January 3, 2020: October 2, 2020 January 3, 2020 (In millions) Total Level 1 Level 2 Total Level 1 Level 2 Assets Deferred compensation plan assets: (1) Equity and fixed-income securities $ 60 $ 60 $ — $ 58 $ 58 $ — Investments measured at NAV: Corporate-owned life insurance 30 29 Total fair value of deferred compensation plan assets $ 90 $ 60 $ — $ 87 $ 58 $ — Derivatives (foreign currency forward contracts) $ 14 $ — $ 14 $ 10 $ — $ 10 Liabilities Deferred compensation plan liabilities: (2) Equity securities and mutual funds $ 3 $ 3 $ — $ 2 $ 2 $ — Investments measured at NAV: Common/collective trusts and guaranteed investment contracts 91 69 Total fair value of deferred compensation plan liabilities $ 94 $ 3 $ — $ 71 $ 2 $ — Derivatives (foreign currency forward contracts) $ 7 $ — $ 7 $ 8 $ — $ 8 Derivatives (treasury lock contracts) $ 130 $ — $ 130 $ 56 $ — $ 56 _______________ (1) Represents diversified assets held in a “rabbi trust” associated with our non-qualified deferred compensation plans, which we include in the “Other current assets” and “Other non-current assets” line items in our Condensed Consolidated Balance Sheet (Unaudited) and which are measured at fair value. (2) Primarily represents obligations to pay benefits under certain non-qualified deferred compensation plans, which we include in the “Compensation and benefits” and “Other long-term liabilities” line items in our Condensed Consolidated Balance Sheet (Unaudited). Under these plans, participants designate investment options (including stock and fixed-income funds), which serve as the basis for measurement of the notional value of their accounts. The following table presents the carrying amounts and estimated fair values of our significant financial instruments that were not measured at fair value (carrying amounts of other financial instruments not listed in the table below approximate fair value due to the short-term nature of those items): October 2, 2020 January 3, 2020 (In millions) Carrying Fair Carrying Fair Long-term debt (including current portion) (1) $ 6,927 $ 7,889 $ 6,951 $ 7,536 _______________ (1) Fair value was estimated using a market approach based on quoted market prices for our debt traded in the secondary market.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Note S — Derivative Instruments and Hedging Activities In the normal course of business, we are exposed to global market risks, including the effect of changes in foreign currency exchange rates and changes in interest rates. We use derivative instruments to manage our exposure to such risks and formally document all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking hedge transactions. We also may enter into derivative instruments that are not designated as hedges and do not qualify for hedge accounting. We recognize all derivatives in our Condensed Consolidated Balance Sheet (Unaudited) at fair value. We do not hold or issue derivatives for speculative trading purposes. Exchange-Rate Risk — Fair Value Hedges. To manage the exposure in our balance sheet to risks from changes in foreign currency exchange rates, we implement fair value hedges. More specifically, we have used foreign currency forward contracts and options to hedge certain balance sheet items, including foreign currency denominated accounts receivable and inventory. Changes in the value of the derivatives and the related hedged items are reflected in earnings, in the “Cost of product sales and services” line item in our Condensed Consolidated Statement of Income (Unaudited). As of October 2, 2020, we had no outstanding foreign currency forward contracts to hedge balance sheet items. The net gains or losses on foreign currency forward contracts designated as fair value hedges were not material in the quarter or three quarters ended October 2, 2020 or in the quarter or three quarters ended September 27, 2019. In addition, no amounts were recognized in earnings in the quarter or three quarters ended October 2, 2020 or in the quarter or three quarters ended September 27, 2019 related to hedged firm commitments that no longer qualify as fair value hedges. Exchange-Rate Risk — Cash Flow Hedges. To manage our exposure to currency risk and market fluctuation risk associated with anticipated cash flows that are probable of occurring in the future, we implement cash flow hedges. More specifically, we use foreign currency forward contracts and options to hedge off-balance sheet future foreign currency commitments, including purchase commitments to suppliers, future committed sales to customers and inter-segment transactions. These derivatives are used to hedge currency exposures from cash flows anticipated across our business segments. We also hedge U.S. Dollar payments to suppliers to maintain our anticipated profit margins in our international operations. These derivatives have only nominal intrinsic value at the time of purchase and have a high degree of correlation to the anticipated cash flows they are designated to hedge. Hedge effectiveness is determined by the correlation of the anticipated cash flows from the hedging instruments and the anticipated cash flows from the future foreign currency commitments through the maturity dates of the derivatives used to hedge these cash flows. These financial instruments are marked-to-market using forward prices and fair value quotes with the offset to other comprehensive income (loss). Gains and losses in AOCI are reclassified to earnings when the related hedged item is recognized in earnings. The cash flow impact of our derivatives is included in the same category in our Condensed Consolidated Statement of Cash Flows (Unaudited) as the cash flows of the related hedged items. Notional amounts are used to measure the volume of foreign currency forward contracts and do not represent exposure to foreign currency losses. At October 2, 2020, we had open foreign currency forward contracts with an aggregate notional amount of $551 million denominated in Canadian Dollars, U.S. Dollars, British Pounds, Euros, New Zealand Dollars and Australian Dollars, to hedge certain forecasted transactions. At October 2, 2020, our foreign currency forward contracts had maturities through 2025. The table below presents the fair values of our derivatives designated as foreign currency hedging instruments in our Condensed Consolidated Balance Sheet (Unaudited) at October 2, 2020 and January 3, 2020: (In millions) October 2, 2020 January 3, 2020 Derivatives designated as hedging instruments: Foreign currency forward contracts (1) Other current assets $ 12 $ 8 Other non-current assets 2 2 Other accrued items 7 6 Other long-term liabilities — 2 _______________ (1) See Note R — Fair Value Measurements in these Notes for a description of the fair value hierarchy related to our foreign currency forward contracts. Net unrealized gains or losses recognized in other comprehensive loss and net gains and losses reclassified from AOCI into earnings from foreign currency derivatives designated as cash flow hedges were not material for the quarter or three quarters ended October 2, 2020 or September 27, 2019. Gains and losses from foreign currency derivatives designated as cash flow hedges are included in the line item in our Condensed Consolidated Statement of Income (Unaudited) associated with the hedged transaction, with the exception of any losses resulting from discontinued cash flow hedges, which are included in the “Engineering, selling and administrative expenses” line item in our Condensed Consolidated Statement of Income (Unaudited). At October 2, 2020, the estimated amount of existing gains to be reclassified into earnings within the next twelve months was not material. Interest-Rate Risk — Cash Flow Hedges. At October 2, 2020, we had two treasury lock agreements (“treasury locks”) with third-party financial institution counterparties with a combined notional amount of $650 million. These treasury locks were initiated in January 2019 (and assumed by us in connection with the L3Harris Merger) to hedge against fluctuations in interest payments due to changes in the benchmark interest rate (10-year U.S. Treasury rate) associated with the anticipated issuance of long-term fixed-rate notes (“New Notes”) to redeem or repay at maturity the entire $650 million outstanding principal amount of our 4.95% Notes due February 15, 2021 (“4.95% 2021 Notes”). We designated these treasury locks as cash flow hedges against fluctuations in interest payments on the New Notes due to changes in the benchmark interest rate prior to issuance of the 4.95% 2021 Notes. If the benchmark interest rate increases during the period of the agreement, the treasury locks position becomes an asset and we receive a cash payment from the counterparty when we terminate the treasury locks upon issuance of the New Notes. Conversely, if the benchmark interest rate decreases, the treasury locks position becomes a liability and we will make a cash payment to the counterparty when we terminate the treasury locks upon issuance of the New Notes. The fair value of the treasury locks is measured using a pricing model that utilizes observable market data such as the benchmark interest rate. See Note R — Fair Value Measurements in these Notes for additional information. At October 2, 2020, the combined fair value of these treasury locks was a liability of $130 million, which is included in the “Other accrued items” line item in our Condensed Consolidated Balance Sheet (Unaudited). The unrealized after-tax loss associated with these treasury locks included in the “Accumulated other comprehensive loss” line item in our Condensed Consolidated Balance Sheet (Unaudited) was $71 million and $16 million at October 2, 2020 and January 3, 2020, respectively. Net gains or losses from interest rate derivatives designated as cash flow hedges recognized in earnings were not material in the quarter or three quarters ended October 2, 2020 or in the quarter or three quarters ended September 27, 2019.

Changes in Estimates

Change in Accounting Estimate [Abstract]
Changes in Estimates	Note T — Changes in Estimates Contract Estimates. Under the POC cost-to-cost method of revenue recognition, a single estimated profit margin is used to recognize profit for each performance obligation over its period of performance. Recognition of profit on a contract requires estimates of the total cost at completion and transaction price as well as measurement of progress towards completion. Due to the long-term nature of many of our contracts, developing the estimated total cost at completion and total transaction price often requires judgment. Factors that must be considered in estimating the cost of the work to be completed include: the nature and complexity of the work to be performed, subcontractor performance and the risk and impact of delayed performance. Factors that must be considered in estimating the total transaction price include contractual cost or performance incentives (such as incentive fees, award fees and penalties) and other forms of variable consideration as well as our historical experience and expectation for performance on the contract. These variable amounts generally are awarded upon achievement of certain negotiated performance metrics, program milestones or cost targets and can be based upon customer discretion. We include such 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. At the outset of each contract, we gauge its complexity and perceived risks and establish an estimated total cost at completion in line with these expectations. After establishing the estimated total cost at completion, we follow a standard Estimate at Completion (“EAC”) process in which we review the progress and performance on our ongoing contracts at least quarterly and, in many cases, more frequently. If we successfully retire risks associated with the technical, schedule and cost aspects of a contract, we may lower our estimated total cost at completion commensurate with the retirement of these risks. Conversely, if we are not successful in retiring these risks, we may increase our estimated total cost at completion. Additionally, as the contract progresses, our estimates of total transaction price may increase or decrease if, for example, we receive award fees that are higher or lower than expected. When adjustments in estimated total costs at completion or in estimated total transaction price are determined, the related impact on operating income is recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Any anticipated losses on these contracts are fully recognized in the period in which the losses become evident. Net EAC adjustments had the following impact to earnings for the periods presented: Quarter Ended Three Quarters Ended (In millions, except per share amounts) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Net EAC adjustments, before income taxes $ 99 $ 62 $ 300 $ 80 Net EAC adjustments, net of income taxes $ 74 $ 46 $ 225 $ 59 Net EAC adjustments, net of income taxes, per diluted common share $ 0.34 $ 0.20 $ 1.03 $ 0.30 Revenue recognized from performance obligations satisfied in prior periods was $121 million and $359 million for the quarter and three quarters ended October 2, 2020, respectively, and $73 million and $116 million for the quarter and three quarters ended September 27, 2019, respectively.

Revenue from Contract with Customer [Abstract]
Backlog	Note H — Contract Assets and Contract Liabilities Contract assets include unbilled amounts typically resulting from revenue recognized exceeding amounts billed to customers for contracts utilizing the percentage of completion (“POC”) cost-to-cost revenue recognition method. We bill customers as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals, upon achievement of contractual milestones or upon deliveries and, in certain arrangements, the customer may withhold payment of a small portion of the contract price until contract completion. Contract liabilities include advance payments and billings in excess of revenue recognized, including deferred revenue associated with extended product warranties. Contract assets and liabilities are reported on a contract-by-contract basis at the end of each reporting period. Contract assets and liabilities in the three quarters ended October 2, 2020 were impacted primarily by divestitures, reclassifications to assets and liabilities of disposal group held for sale, accelerated progress payments due to the U.S. Government's increase in the progress payment rate from 80 percent to 90 percent and the timing of contractual billing milestones.

For the quarter and three quarters ended October 2, 2020, we recognized as revenue $0.1 billion and $0.8 billion, respectively, of contract liabilities that were outstanding at January 3, 2020. For the quarter ended September 27, 2019, we recognized as revenue $0.6 billion of contract liabilities that were outstanding at June 29, 2019. Because of the L3Harris Merger and our change in fiscal year-end from June to December, revenue recognized in the three quarters ended September 27, 2019 from contract liabilities that were outstanding at the end of the prior year is not comparable. Note U — Backlog Backlog, which is the equivalent of our remaining performance obligations, represents the future revenue we expect to recognize as we perform on our current contracts. Backlog comprises both funded backlog (i.e., firm orders for which funding is authorized and appropriated) and unfunded backlog. Backlog excludes unexercised contract options and potential orders under ordering-type contracts, such as indefinite delivery, indefinite quantity contracts. At October 2, 2020, our ending backlog was $20.8 billion. We expect to recognize approximately 65 percent of the revenue associated with this backlog by the end of 2021 and approximately 80 percent by the end of 2022, with the remainder to be recognized thereafter. At January 3, 2020, our ending backlog was $20.6 billion, including $380 million of backlog associated with the airport security and automation business, which was divested during the quarter ended July 3, 2020.

Segment Reporting [Abstract]
Business Segment Information	Note V — Business Segment Information We adjusted our segment reporting due to the L3Harris Merger to reflect our new organizational structure that was effective June 29, 2019 and announced July 1, 2019. We structure our operations primarily around the products and services we sell and the markets we serve, and we report the financial results of our operations in the following four operating segments, which are also our reportable segments and are referred to as our business segments: • Integrated Mission Systems, including multi-mission ISR and communication systems; integrated electrical and electronic systems for maritime platforms; and advanced electro-optical and infrared solutions; • Space and Airborne Systems, including space payloads, sensors and full-mission solutions; classified intelligence and cyber defense; avionics; and electronic warfare; • Communication Systems, including tactical communications; broadband communications; integrated vision solutions; and public safety; and • Aviation Systems, including defense aviation products; commercial aviation products; commercial and military pilot training; and mission networks for air traffic management. During the quarter ended April 3, 2020, we further adjusted our segment reporting to better align our businesses and transferred two businesses between our Integrated Mission Systems and Space and Airborne Systems segments. The historical results, discussion and presentation of our business segments as set forth in this Report reflect the impact of the above adjustments for all periods presented. There is no impact on our previously reported consolidated statements of income, balance sheets, statements of cash flows or statements of equity resulting from these adjustments. As noted in Note C — Business Divestitures and Assets Sales and elsewhere in these Notes, during 2019 and 2020, we completed the following business divestitures: • The divestiture of the Harris Night Vision business, completed on September 13, 2019, the results of which are included in “Other non-reportable business segments” through the date of divestiture; • The divestiture of the airport security and automation business, completed on May 4, 2020, the results of which are reported as part of our Aviation Systems segment through the date of divestiture; • The divestiture of the Applied Kilovolts and Analytical Instrumentation business, completed on May 15, 2020, the results of which are reported as part of our Space and Airborne Systems segment through the date of divestiture; and • The divestiture of the EOTech business, completed on July 31, 2020, the results of which are reported as part of our Communication Systems segment through the date of divestiture. The accounting policies of our business segments are the same as those described in Note 1: “Significant Accounting Policies” in the Notes to Consolidated Financial Statements in our Fiscal Transition Period Form 10-KT. We evaluate each segment’s performance based on its operating income or loss, which we define as profit or loss from operations before income taxes, including pension income and excluding interest income and expense, royalties and related intellectual property expenses, equity method investment income or loss and gains or losses from securities and other investments. Inter-segment sales are generally transferred at cost to the buying segment, and the sourcing segment may recognize a profit that is eliminated. The “Corporate eliminations” line item in the table below represents the elimination of inter-segment sales. Corporate expenses are allocated to our operating segments using an allocation methodology prescribed by U.S. Government regulations for government contractors. The “Pension adjustment” line item in the table below represents the reconciliation of the non-service components of net periodic pension and postretirement benefit costs, which are a component of segment operating income but are included in the “Non-operating income” line item in our Condensed Consolidated Statement of Income (Unaudited). The non-service components of net periodic pension and postretirement benefit costs include interest cost, expected return on plan assets and amortization of net actuarial gain or loss. Segment revenue, segment operating income (loss) and a reconciliation of segment operating income to total income from continuing operations before income taxes are as follows: Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Revenue Integrated Mission Systems $ 1,372 $ 1,292 $ 4,073 $ 1,317 Space and Airborne Systems 1,249 1,173 3,690 3,148 Communication Systems 1,094 1,032 3,300 2,221 Aviation Systems 792 948 2,603 1,278 Other non-reportable business segments (1) — 23 — 102 Corporate eliminations (44) (37) (132) (42) Total revenue $ 4,463 $ 4,431 $ 13,534 $ 8,024 Income From Continuing Operations Before Income Taxes Segment Operating Income (Loss): Integrated Mission Systems $ 213 $ 176 $ 638 $ 182 Space and Airborne Systems 231 230 687 599 Communication Systems 273 234 788 577 Aviation Systems 100 127 (46) 163 Other non-reportable business segments (1) — — — 14 Unallocated corporate expenses (2) (23) (93) (113) (94) L3Harris Merger-related transaction, integration and restructuring expenses (27) (170) (95) (222) L3Harris Merger-related restructuring charges — (111) (7) (111) Amortization of acquisition-related intangibles (3) (176) (123) (529) (173) Business divestiture-related (losses) gains (10) 229 (62) 229 Pension adjustment (97) (80) (292) (173) Non-operating income 96 79 296 173 Net interest expense (62) (58) (190) (139) Total income from continuing operations before income taxes $ 518 $ 440 $ 1,075 $ 1,025 _______________ (1) Includes the operating results of the Harris Night Vision business prior to the divestiture on September 13, 2019. See Note C — Business Divestitures and Assets Sales in these Notes for more information. (2) For the quarter ended October 2, 2020, includes $2 million of divestiture-related expenses, and for the three quarters ended October 2, 2020, includes (i) $31 million of additional cost of sales related to the fair value step-up in inventory sold (see Note B — Business Combination in these Notes for more information); (ii) a $14 million non-cash goodwill impairment charge related to a potential divestiture; (iii) $11 million of divestiture-related expenses; and (iv) a $5 million non-cash goodwill impairment charge related to the divestiture of the Applied Kilovolts and Analytical Instrumentation business. For the quarter and three quarters ended September 27, 2019, includes (i) $92 million of additional cost of sales related to the fair value step-up in inventory sold; (ii) a $12 million gain on the sale of an asset group; and (iii) a $12 million non-cash cumulative adjustment to lease expense. (3) Includes $151 million and $454 million for the quarter and three quarters ended October 2, 2020, respectively, and $98 million for the quarter and three quarters ended September 27, 2019 of amortization of identifiable intangible assets acquired as a result of the L3Harris Merger. Also includes $25 million and $75 million, respectively, for the quarters and three quarters ended October 2, 2020 and September 27, 2019, of amortization of identifiable intangible assets acquired as a result of our acquisition of Exelis Inc. in fiscal 2015. Because the L3Harris Merger and the acquisition of Exelis Inc. benefited the entire Company as opposed to any individual segment, the amortization of identifiable intangible assets acquired was not allocated to any segment. Disaggregation of Revenue We disaggregate revenue for all four business segments by customer relationship, contract type and geographical region. We believe these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Integrated Mission Systems: Integrated Mission Systems revenue is primarily derived from U.S. Government development and production contracts and is generally recognized over time using the POC cost-to-cost revenue recognition method. Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Revenue By Customer Relationship Prime contractor $ 910 $ 882 $ 2,717 $ 894 Subcontractor 462 410 1,356 423 $ 1,372 $ 1,292 $ 4,073 $ 1,317 Revenue By Contract Type Fixed-price (1) $ 1,041 $ 1,010 $ 3,064 $ 1,035 Cost-reimbursable 331 282 1,009 282 $ 1,372 $ 1,292 $ 4,073 $ 1,317 Revenue By Geographical Region United States $ 1,097 $ 1,071 $ 3,240 $ 1,086 International 275 221 833 231 $ 1,372 $ 1,292 $ 4,073 $ 1,317 _______________ (1) Includes revenue derived from time-and-materials contracts.

Communication Systems: Communication Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems and services. Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Revenue By Customer Relationship (1) Prime contractor $ 759 $ 679 $ 2,248 Subcontractor 335 353 1,052 $ 1,094 $ 1,032 $ 3,300 Revenue By Contract Type (1) Fixed-price (2) $ 935 $ 875 $ 2,804 Cost-reimbursable 159 157 496 $ 1,094 $ 1,032 $ 3,300 Revenue by Geographical Region United States $ 749 $ 721 $ 2,427 $ 1,423 International 345 311 873 798 $ 1,094 $ 1,032 $ 3,300 $ 2,221 _______________ (1) Prior to the L3Harris Merger, Communication Systems did not recognize significant revenue for customer-specific products and systems, and currently, such customer arrangements primarily exist at operating businesses acquired in connection with the L3Harris Merger. The “Revenue by Customer Relationship” and “Revenue by Contract Type” disaggregation categories were added beginning in the Fiscal Transition Period to best depict how the nature, amount, timing and uncertainty of revenue and cash flows from these types of customer arrangements are affected by economic factors. (2) Includes revenue derived from time-and-materials contracts. Aviation Systems: Aviation Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems and services.

Identifiable intangible asset balances recorded as Corporate assets were approximately $8.2 billion and $8.5 billion at October 2, 2020 and January 3, 2020, respectively. Corporate assets also consisted of cash, income taxes receivable, deferred income taxes, deferred compensation plan investments, buildings and equipment, as well as any assets and liabilities from discontinued operations and divestitures.

Legal Proceedings And Contingencies [Abstract]
Legal Proceedings and Contingencies	Note W — Legal Proceedings and Contingencies From time to time, as a normal incident of the nature and kind of businesses in which we are or were engaged, various claims or charges are asserted and litigation or arbitration is commenced by or against us arising from or related to matters, including, but not limited to: product liability; personal injury; patents, trademarks, trade secrets or other intellectual property; labor and employee disputes; commercial or contractual disputes; strategic acquisitions or divestitures; the prior sale or use of former products allegedly containing asbestos or other restricted materials; breach of warranty; or environmental matters. Claimed amounts against us may be substantial but may not bear any reasonable relationship to the merits of the claim or the extent of any real risk of court or arbitral awards. We record accruals for losses related to those matters against us that we consider to be probable and that can be reasonably estimated. Gain contingencies, if any, are recognized when they are realized, and legal costs generally are expensed when incurred. At October 2, 2020, our accrual for the potential resolution of lawsuits, claims or proceedings that we consider probable of being decided unfavorably to us was not material. Although it is not feasible to predict the outcome of these matters with certainty, it is reasonably possible that some lawsuits, claims or proceedings may be disposed of or decided unfavorably to us and in excess of the amounts currently accrued. Based on available information, in the opinion of management, settlements, arbitration awards and final judgments, if any, that are considered probable of being rendered against us in litigation or arbitration in existence at October 2, 2020 are reserved against or would not have a material adverse effect on our financial condition, results of operations, cash flows or equity.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Condensed Consolidated Financial Statements (Unaudited) include the accounts of L3Harris Technologies, Inc. and its consolidated subsidiaries. As used in these Notes to Condensed Consolidated Financial Statements (Unaudited) (these “Notes”), the terms “L3Harris,” “Company,” “we,” “our” and “us” refer to L3Harris Technologies, Inc. and its consolidated subsidiaries. Intracompany transactions and accounts have been eliminated in consolidation. The accompanying Condensed Consolidated Financial Statements (Unaudited) have been prepared by L3Harris, without an audit, in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, such interim financial statements do not include all information and footnotes necessary for a complete presentation of financial condition, results of operations, cash flows and equity in conformity with GAAP for annual financial statements. In the opinion of management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of our financial condition, results of operations, cash flows and equity for the periods presented therein. The results for the quarter and three quarters ended October 2, 2020 are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. The balance sheet at January 3, 2020 has been derived from our audited financial statements, but does not include all of the information and footnotes required by GAAP for annual financial statements. We provide complete, audited financial statements in our Transition Report on Form 10-KT for the fiscal transition period from June 29, 2019 to January 3, 2020 (our “Fiscal Transition Period Form 10-KT”), which includes information and footnotes required by the rules and regulations of the SEC. The information included in this Quarterly Report on Form 10-Q (this “Report”) should be read in conjunction with the Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements included in our Fiscal Transition Period Form 10-KT. Amounts contained in this Report may not always add to totals due to rounding. L3Harris Merger See Note B — Business Combination in these Notes for information related to the business combination in which Harris Corporation (“Harris”) and L3 Technologies, Inc. (“L3”) combined their respective businesses in an all-stock merger that resulted in our combined Company, L3Harris Technologies, Inc. Due to the L3Harris Merger (as defined in Note B — Business Combination in these Notes), the three quarters ended October 2, 2020 reflect the results of the combined Company, while the three quarters ended September 27, 2019 reflect the results of only Harris operating businesses for the two quarters ended June 28, 2019 and the results of the combined Company for the quarter ended September 27, 2019.
Organizational Structure and Business Segments	Organizational Structure We implemented a new organizational structure effective on June 29, 2019, which resulted in changes to our operating segments, which are also reportable segments and referred to as our business segments. During the quarter ended April 3, 2020, we further adjusted our segment reporting to better align our businesses and transferred two businesses between our Integrated Mission Systems and Space and Airborne Systems segments. The historical results, discussion and presentation of our business segments as set forth in the accompanying Condensed Consolidated Financial Statements (Unaudited) and these Notes reflect the impact of these changes for all periods presented in order to present segment information on a comparable basis. There is no impact on our previously reported consolidated statements of income, balance sheets, statements of cash flows or statements of equity resulting from these changes. We adjusted our segment reporting due to the L3Harris Merger to reflect our new organizational structure that was effective June 29, 2019 and announced July 1, 2019. We structure our operations primarily around the products and services we sell and the markets we serve, and we report the financial results of our operations in the following four operating segments, which are also our reportable segments and are referred to as our business segments: • Integrated Mission Systems, including multi-mission ISR and communication systems; integrated electrical and electronic systems for maritime platforms; and advanced electro-optical and infrared solutions; • Space and Airborne Systems, including space payloads, sensors and full-mission solutions; classified intelligence and cyber defense; avionics; and electronic warfare; • Communication Systems, including tactical communications; broadband communications; integrated vision solutions; and public safety; and • Aviation Systems, including defense aviation products; commercial aviation products; commercial and military pilot training; and mission networks for air traffic management. During the quarter ended April 3, 2020, we further adjusted our segment reporting to better align our businesses and transferred two businesses between our Integrated Mission Systems and Space and Airborne Systems segments. The historical results, discussion and presentation of our business segments as set forth in this Report reflect the impact of the above adjustments for all periods presented. There is no impact on our previously reported consolidated statements of income, balance sheets, statements of cash flows or statements of equity resulting from these adjustments. As noted in Note C — Business Divestitures and Assets Sales and elsewhere in these Notes, during 2019 and 2020, we completed the following business divestitures: • The divestiture of the Harris Night Vision business, completed on September 13, 2019, the results of which are included in “Other non-reportable business segments” through the date of divestiture; • The divestiture of the airport security and automation business, completed on May 4, 2020, the results of which are reported as part of our Aviation Systems segment through the date of divestiture; • The divestiture of the Applied Kilovolts and Analytical Instrumentation business, completed on May 15, 2020, the results of which are reported as part of our Space and Airborne Systems segment through the date of divestiture; and • The divestiture of the EOTech business, completed on July 31, 2020, the results of which are reported as part of our Communication Systems segment through the date of divestiture. The accounting policies of our business segments are the same as those described in Note 1: “Significant Accounting Policies” in the Notes to Consolidated Financial Statements in our Fiscal Transition Period Form 10-KT. We evaluate each segment’s performance based on its operating income or loss, which we define as profit or loss from operations before income taxes, including pension income and excluding interest income and expense, royalties and related intellectual property expenses, equity method investment income or loss and gains or losses from securities and other investments. Inter-segment
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying Condensed Consolidated Financial Statements (Unaudited) and these Notes and related disclosures. These estimates and assumptions are based on experience and other information available prior to
Adoption of New Accounting Standards	Adoption of New Accounting Standards Effective January 3, 2020, we adopted Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments on a modified retrospective basis . The new standard replaces the existing impairment model, under which impairment of financial instruments, including accounts receivable and contract assets, is recognized when it becomes probable a loss has been incurred, with a model that requires recognition of expected credit losses over the estimated life of an asset at inception and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Adopting this standard did not have a material impact on our financial condition, results of operations, cash flows or equity.
Restructuring and Other Exit Costs	We record charges for restructuring and other exit activities related to sales or terminations of product lines, closures or relocations of business activities, changes in management structure and fundamental reorganizations that affect the nature and focus of operations. Such charges include termination benefits, contract termination costs and costs to consolidate facilities or relocate employees. We record these charges at their fair value when incurred. In cases where employees are required to render service until they are terminated in order to receive the termination benefits and will be retained beyond the minimum retention period, we record the expense ratably over the future service period. These charges are included as a component of the “Engineering, selling and administrative expenses” line item in our Condensed Consolidated Statement of Income (Unaudited).
Fair Value Measurements	Fair value is defined as the price that would be received for an asset or the price that would be paid to transfer a liability in the principal market or most advantageous market in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed using the best information available in the circumstances. In certain instances, fair value is estimated using quoted market prices obtained from external pricing services. In obtaining such data from the external pricing services, we have evaluated the methodologies used to develop the estimate of fair value in order to assess whether such valuations are representative of fair value, including net asset value (“NAV”). Additionally, in certain circumstances, the NAV reported by an asset manager may be adjusted when sufficient evidence indicates NAV is not representative of fair value.
Disaggregation of Revenue	Disaggregation of Revenue We disaggregate revenue for all four business segments by customer relationship, contract type and geographical region. We believe these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Integrated Mission Systems: Integrated Mission Systems revenue is primarily derived from U.S. Government development and production contracts and is generally recognized over time using the POC cost-to-cost revenue recognition method. Space and Airborne Systems: Space and Airborne Systems revenue is primarily derived from U.S. Government development and production contracts and is generally recognized over time using the POC cost-to-cost revenue recognition method. Communication Systems: Communication Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems and services. Aviation Systems: Aviation Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems and services.

See Note C — Business Divestitures and Assets Sales in these Notes for more information. (2) For the quarter ended October 2, 2020, includes $2 million of divestiture-related expenses, and for the three quarters ended October 2, 2020, includes (i) $31 million of additional cost of sales related to the fair value step-up in inventory sold (see Note B — Business Combination in these Notes for more information); (ii) a $14 million non-cash goodwill impairment charge related to a potential divestiture; (iii) $11 million of divestiture-related expenses; and (iv) a $5 million non-cash goodwill impairment charge related to the divestiture of the Applied Kilovolts and Analytical Instrumentation business. For the quarter and three quarters ended September 27, 2019, includes (i) $92 million of additional cost of sales related to the fair value step-up in inventory sold; (ii) a $12 million gain on the sale of an asset group; and (iii) a $12 million non-cash cumulative adjustment to lease expense.

Because the L3Harris Merger and the acquisition of Exelis Inc. benefited the entire Company as opposed to any individual segment, the amortization of identifiable intangible assets acquired was not allocated to any segment.
Schedule of Disaggregation of Revenue by Segment	Disaggregation of Revenue We disaggregate revenue for all four business segments by customer relationship, contract type and geographical region. We believe these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Integrated Mission Systems: Integrated Mission Systems revenue is primarily derived from U.S. Government development and production contracts and is generally recognized over time using the POC cost-to-cost revenue recognition method. Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Revenue By Customer Relationship Prime contractor $ 910 $ 882 $ 2,717 $ 894 Subcontractor 462 410 1,356 423 $ 1,372 $ 1,292 $ 4,073 $ 1,317 Revenue By Contract Type Fixed-price (1) $ 1,041 $ 1,010 $ 3,064 $ 1,035 Cost-reimbursable 331 282 1,009 282 $ 1,372 $ 1,292 $ 4,073 $ 1,317 Revenue By Geographical Region United States $ 1,097 $ 1,071 $ 3,240 $ 1,086 International 275 221 833 231 $ 1,372 $ 1,292 $ 4,073 $ 1,317 _______________ (1) Includes revenue derived from time-and-materials contracts. Space and Airborne Systems: Space and Airborne Systems revenue is primarily derived from U.S. Government development and production contracts and is generally recognized over time using the POC cost-to-cost revenue recognition method. Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Revenue By Customer Relationship Prime contractor $ 674 $ 705 $ 2,006 $ 1,867 Subcontractor 575 468 1,684 1,281 $ 1,249 $ 1,173 $ 3,690 $ 3,148 Revenue By Contract Type Fixed-price (1) $ 703 $ 702 $ 2,075 $ 1,834 Cost-reimbursable 546 471 1,615 1,314 $ 1,249 $ 1,173 $ 3,690 $ 3,148 Revenue By Geographical Region United States $ 1,067 $ 1,018 $ 3,124 $ 2,750 International 182 155 566 398 $ 1,249 $ 1,173 $ 3,690 $ 3,148 _______________ (1) Includes revenue derived from time-and-materials contracts. Communication Systems: Communication Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems and services. Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Revenue By Customer Relationship (1) Prime contractor $ 759 $ 679 $ 2,248 Subcontractor 335 353 1,052 $ 1,094 $ 1,032 $ 3,300 Revenue By Contract Type (1) Fixed-price (2) $ 935 $ 875 $ 2,804 Cost-reimbursable 159 157 496 $ 1,094 $ 1,032 $ 3,300 Revenue by Geographical Region United States $ 749 $ 721 $ 2,427 $ 1,423 International 345 311 873 798 $ 1,094 $ 1,032 $ 3,300 $ 2,221 _______________ (1) Prior to the L3Harris Merger, Communication Systems did not recognize significant revenue for customer-specific products and systems, and currently, such customer arrangements primarily exist at operating businesses acquired in connection with the L3Harris Merger. The “Revenue by Customer Relationship” and “Revenue by Contract Type” disaggregation categories were added beginning in the Fiscal Transition Period to best depict how the nature, amount, timing and uncertainty of revenue and cash flows from these types of customer arrangements are affected by economic factors. (2) Includes revenue derived from time-and-materials contracts. Aviation Systems: Aviation Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems and services. Quarter Ended Three Quarters Ended (In millions) October 2, 2020 September 27, 2019 October 2, 2020 September 27, 2019 Revenue By Customer Relationship Prime contractor $ 511 $ 584 $ 1,689 $ 904 Subcontractor 281 364 914 374 $ 792 $ 948 $ 2,603 $ 1,278 Revenue By Contract Type Fixed-price (1) $ 646 $ 784 $ 2,114 $ 1,070 Cost-reimbursable 146 164 489 208 $ 792 $ 948 $ 2,603 $ 1,278 Revenue By Geographical Region United States $ 687 $ 724 $ 2,132 $ 1,045 International 105 224 471 233 $ 792 $ 948 $ 2,603 $ 1,278 _______________ (1) Includes revenue derived from time-and-materials contracts.
Schedule of Total Assets by Business Segment	Total assets by business segment are summarized below: (In millions) October 2, 2020 January 3, 2020 Total Assets Integrated Mission Systems $ 8,752 $ 7,888 Space and Airborne Systems 6,902 6,837 Communication Systems 5,643 5,930 Aviation Systems 5,231 7,569 Corporate (1) 10,617 10,112 Total Assets $ 37,145 $ 38,336 _______________ (1) Identifiable intangible assets acquired in connection with the L3Harris Merger in the quarter ended September 27, 2019 and our acquisition of Exelis Inc. in fiscal 2015 were recorded as Corporate assets because they benefited the entire Company as opposed to any individual segment. Identifiable intangible asset balances recorded as Corporate assets were approximately $8.2 billion and $8.5 billion at October 2, 2020 and January 3, 2020, respectively. Corporate assets also consisted of cash, income taxes receivable, deferred income taxes, deferred compensation plan investments, buildings and equipment, as well as any assets and liabilities from discontinued operations and divestitures.
