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 and cash flows for the periods presented therein. The results for the quarter and two quarters ended July 3, 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. On October 12, 2018, Harris Corporation, a Delaware corporation (“Harris”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with L3 Technologies, Inc., a Delaware corporation (“L3”), 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.” (“L3Harris”), 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. Because of the L3Harris Merger, the quarter and two quarters ended July 3, 2020 reflect the results of the combined company, while the quarter and two quarters ended June 28, 2019 reflect the results of only Harris operating businesses. We accounted for the L3Harris Merger under the acquisition method of accounting. Under the acquisition method of accounting, we were required to measure identifiable assets acquired, liabilities assumed and any noncontrolling interests in the acquiree at their fair values as of the Closing Date. The excess of the consideration transferred over those fair values was recorded as goodwill. See Note B — Business Combination in these Notes for additional information related to the L3Harris Merger. 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. 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. On September 13, 2019, we completed the divestiture of the Harris Night Vision business to Elbit Systems of America, LLC, a subsidiary of Elbit Systems Ltd., for $350 million (net cash proceeds of $343 million after selling costs and purchase price adjustments). The Harris Night Vision business was not included in any of the operating segments in our new organizational structure and the operating results of the Harris Night Vision business through the date of the divestiture are discussed and presented as part of “Other non-reportable business segments” in this Report. 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 $951 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 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. 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. On March 20, 2020, we entered into a definitive sale agreement to sell our EOTech business for $42 million, subject to customary adjustments and closing conditions as set forth in the definitive agreement. The EOTech business, which is reported as part of our Communications Systems segment, manufactures holographic sighting systems, magnified field optics and accessories for military, law enforcement and commercial markets around the world. The assets and liabilities of the EOTech business were classified as held for sale in our Condensed Consolidated Balance Sheet (Unaudited) at July 3, 2020. We completed the divestiture of the EOTech business on July 31, 2020. 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 were classified as held for sale in our Condensed Consolidated Balance Sheet (Unaudited) at July 3, 2020. The income before income taxes of the other AS disposal group were not material for the quarter and two quarters ended July 3, 2020. We expect to complete the divestiture of the other AS disposal group by the end of 2020. See Note C — Business Divestitures and Assets Sales and Note X — Subsequent Events in these Notes for more information regarding the divestitures. Amounts contained in this Report may not always add to totals due to rounding. 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 receivables 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 or cash flows.

Business Combinations [Abstract]
Business Combination	Note B — Business Combination On October 12, 2018, Harris entered into the Merger Agreement with L3 and 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 closing of the L3Harris Merger occurred on June 29, 2019. 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 of L3Harris common stock. 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. Under the acquisition method of accounting, we were required to measure identifiable assets acquired, liabilities assumed and any noncontrolling interests in the acquiree at their fair values as of the Closing Date. 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 RSUs 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: Preliminary Fair Value as of September 27, 2019 Measurement Period Adjustments Adjusted Fair Value as of July 3, 2020 (In millions) 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 is 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 deviate 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 $17 million and $40 million of revenue in the quarter and two quarters ended July 3, 2020, respectively, for amortization of net off-market contract liabilities (including 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: $18 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 identified 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 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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Pre-merger L3Harris integration costs $ — $ 17 $ — $ 30 Transaction costs — 19 — 22 Additional cost of sales related to the fair value step-up in inventory sold 16 — 31 — Restructuring - workforce reduction 7 — 7 — Integration costs recognized as incurred 37 — 68 — $ 60 $ 36 $ 106 $ 52 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 summary, prepared on a pro forma basis, presents our unaudited consolidated results of operations for the quarter and two quarters ended June 28, 2019 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 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.

Discontinued Operations and Disposal Groups [Abstract]
Business Divestitures and Assets Sales	Note C — Business Divestitures and Assets Sales Airport security and automation business. On May 4, 2020, we completed the divestiture of our airport security and automation business to Leidos, Inc. for $1 billion (net cash proceeds of $951 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, which is included in the “Engineering, selling and administrative expenses” line item in our Condensed Consolidated Statement of Income (Unaudited). 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. The airport security and automation business had a net loss before income taxes of $3 million for the quarter ended July 3, 2020 and net income before income taxes of $9 million for the two quarters ended July 3, 2020. 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. 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. 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 for the Applied Kilovolts and Analytical Instrumentation business was not material for the quarter or two quarters ended July 3, 2020. 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 two quarters ended July 3, 2020. EOTech business. On March 20, 2020, we entered into a definitive agreement to sell our EOTech business for $42 million, subject to customary purchase price adjustments and customary closing conditions as set forth in the definitive agreement. The EOTech business, which is reported as part of our Communication Systems segment, manufactures holographic sighting systems, magnified field optics and accessories for military, law enforcement and commercial markets around the world. The assets and liabilities of the EOTech business disposal group were classified as held for sale in our Condensed Consolidated Balance Sheet (Unaudited) at July 3, 2020. 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. The carrying amounts of assets and liabilities of the EOTech business disposal group that were classified as held for sale in our Condensed Consolidated Balance Sheet (Unaudited) at July 3, 2020 were $46 million and $7 million, respectively. We completed the sale of the EOTech business on July 31, 2020. 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 – the other AS disposal group. The income before income taxes of the other AS disposal group were not material for the quarter and two quarters ended July 3, 2020. 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. These charges are included in the “Impairment of goodwill and other assets” and “Engineering, selling and administrative expenses” line items in our Condensed Consolidated Statement of Income (Unaudited) for the quarter ended July 3, 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 July 3, 2020 were $42 million and $14 million, respectively. We expect to complete the sale of the other AS disposal group by the end of 2020. 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. During the quarter ended July 3, 2020, we finalized the purchase price adjustments and recognized a non-cash adjustment of $12 million related to working capital, which decreased the gain initially recognized. 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 two quarters ended June 28, 2019 in this Report. Income before income taxes for the Harris Night Vision business was $8 million and $14 million for the quarter and two quarters ended June 28, 2019, respectively. 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.

Share-based Payment Arrangement [Abstract]
Stock Options and Other Share-Based Compensation	Note D — Stock Options and Other Share-Based Compensation As of July 3, 2020, we had options or other share-based compensation outstanding under two Harris shareholder-approved stock incentive plans (“SIPs”), the Harris Corporation 2005 Equity Incentive Plan (As Amended and Restated Effective August 27, 2010) and the Harris Corporation 2015 Equity Incentive Plan (the “2015 EIP”), 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 $24 million and $40 million for the quarter and two quarters ended July 3, 2020, respectively, and $15 million and $29 million for the quarter and two quarters ended June 28, 2019, respectively. 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 47,990 and 498,173 for the quarter and two quarters ended July 3, 2020, respectively, and 372,195 and 519,371 for the quarter and two quarters ended June 28, 2019, respectively. Awards granted to participants under L3Harris SIPs during the quarter ended July 3, 2020 consisted of 39,941 restricted stock units and no stock options or performance stock units. Awards granted to participants under L3Harris SIPs during the two quarters ended July 3, 2020 consisted of 246,307 restricted stock units, 583,200 stock options and 203,606 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 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 During the quarter and two quarters ended July 3, 2020, we recorded $7 million of restructuring charges in connection with the L3Harris Merger. At July 3, 2020, we had liabilities of $30 million associated with these and previous 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 two quarters ended July 3, 2020, we recorded $11 million and $14 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. During the quarter and two quarters ended July 3, 2020, we also 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 July 3, 2020, we had liabilities of $12 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 July 3, 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 two quarters ended July 3, 2020 were as follows: Employee severance-related costs Facilities consolidation and other exit costs Total (In millions) Balance at January 3, 2020 $ 58 $ 7 $ 65 Additional provisions 22 — 22 Payments (38) (1) (39) Total changes (16) (1) (17) Balance at July 3, 2020 $ 42 $ 6 $ 48

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 two quarters ended July 3, 2020 were impacted by reclassifications to assets and liabilities of disposal groups held for sale, a decrease in the receipt of advance payments, the timing of contractual billing milestones and the impairment loss described below. 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: July 3, 2020 January 3, 2020 (In millions) Contract assets $ 2,281 $ 2,459 Contract liabilities, current (1,106) (1,214) Contract liabilities, non-current (1) (76) (87) Net contract assets $ 1,099 $ 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: July 3, 2020 January 3, 2020 (In millions) Unbilled contract receivables, gross $ 3,890 $ 3,690 Progress payments and advances (1,609) (1,231) $ 2,281 $ 2,459 Impairment losses related to our contract assets were not material for the quarter ended July 3, 2020 or the quarter or two quarters ended June 28, 2019. In the two quarters ended July 3, 2020, we recorded impairment losses of $13 million at our Aviation Systems segment to reflect an increase in expected credit losses associated with the COVID-19-related downturn in our Commercial Aviation Solutions sector and its impact on global air traffic and customer operations. For the quarter and two quarters ended July 3, 2020, we recognized as revenue $265 million and $749 million of contract liabilities, respectively, that were outstanding at January 3, 2020. For the quarter and two quarters ended June 28, 2019, we recognized as revenue $28 million and $80 million of contract liabilities, respectively, that were outstanding at June 29, 2018. 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 July 3, 2020, our ending backlog was $19.8 billion. We expect to recognize approximately two-thirds of the revenue associated with this backlog within the next twelve months and approximately three-fourths of the revenue associated with this backlog within the next three years. 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.

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 two quarters ended July 3, 2020, were as follows: Integrated Mission Systems Space and Airborne Systems Communication Systems Aviation Systems Total (In millions) Balance at January 3, 2020 $ 5,768 $ 5,131 $ 4,243 $ 4,859 $ 20,001 Goodwill decrease from divestitures (1) — (2) — (531) (533) Decrease from reclassification to assets of disposal group held for sale (2) — — (9) — (9) Impairment of goodwill — (5) — (364) (369) Currency translation adjustments 3 (7) (2) (5) (11) Other (including adjustments to previously estimated fair value of assets acquired and liabilities assumed) (3) 740 124 (81) (847) (64) Balance at July 3, 2020 $ 6,511 $ 5,241 $ 4,151 $ 3,112 $ 19,015 _______________ (1) During the quarter ended July 3, 2020, we completed the divestitures of our airport security and automation business and our Applied Kilovolts and Analytical Instrumentation business and derecognized $533 million of goodwill as the part of determining the gain or loss on the sale of these businesses. See Note C — Business Divestitures and Assets Sales in these Notes for additional information. (2) In connection with the then-pending divestiture of our EOTech business, we assigned $9 million of goodwill to “Assets of disposal groups held for sale” in our Condensed Consolidated Balance Sheet (Unaudited) as of July 3, 2020. See Note C — Business Divestitures and Assets Sales in these Notes for additional information. (3) 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 Quarter Ended April 3, 2020: 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 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. Consequently, in connection with the preparation of our financial statements for the quarter ended April 3, 2020, we performed a quantitative impairment test 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 this impairment test, we concluded that goodwill related to our Commercial Aviation Solutions reporting unit was impaired as of April 3, 2020 and we recorded a non-cash impairment charge of $296 million (including $28 million attributable to noncontrolling interests) in the “Impairment of goodwill and other assets” line item in our Condensed Consolidated Statement of Income (Unaudited) for the quarter ended April 3, 2020. The goodwill impairment charge is primarily not deductible for tax purposes. Quarter Ended July 3, 2020: 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 July 3, 2020. Although our cash flow projections for the Commercial Aviation Solutions reporting unit did not change significantly compared with the projected cash flows used in our analysis 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 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 quarter ended July 3, 2020, we performed a quantitative test 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 this impairment test, we concluded that goodwill related to our Commercial Aviation Solutions reporting unit was impaired as of July 3, 2020, primarily due to a significant increase in the weighted-average cost of capital (“WACC”) rate used to discount the projected cash flows of our Commercial Aviation Solutions reporting unit to their present values, and we recorded a non-cash impairment charge of $54 million (including $8 million attributable to noncontrolling interests) in the “Impairment of goodwill and other assets” line item in our Condensed Consolidated Statement of Income (Unaudited) for the quarter ended July 3, 2020. The goodwill impairment charge is 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. 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 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 quarter ended July 3, 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 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 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 as of April 3, 2020 or July 3, 2020. Intangible assets are summarized below: July 3, 2020 January 3, 2020 Gross Accumulated Amortization Net Carrying Amount (1) Gross Carrying Amount Accumulated Amortization Net Carrying Amount (In millions) Customer relationships $ 6,911 $ 950 $ 5,961 $ 6,518 $ 653 $ 5,865 Developed technologies 667 222 445 768 183 585 Contract backlog 19 13 6 — — — Trade names — divisions 138 40 98 165 35 130 Other 4 2 2 10 4 6 Total intangible assets subject to amortization 7,739 1,227 6,512 7,461 875 6,586 In-process research and development 21 — 21 69 — 69 L3 trade name 1,803 — 1,803 1,803 — 1,803 Total intangibles assets $ 9,563 $ 1,227 $ 8,336 $ 9,333 $ 875 $ 8,458 (1) During the quarter ended July 3, 2020, we completed the divestitures of the airport security and automation business and Applied Kilovolts and Analytical Instrumentation business and derecognized $286 million of intangibles as part of the gain or loss on the sale of these businesses. Additionally, in connection with two pending divestitures, we reclassified $15 million of intangibles to “Assets of disposal groups held for sale” in our Condensed Consolidated Balance Sheet (Unaudited) as of July 3, 2020. See Note C — Business Divestitures and Assets Sales in these Notes for additional information regarding divestitures. For the quarter and two quarters ended July 3, 2020, amortization expense related to intangible assets was $209 million and $367 million, respectively, and primarily related to the L3Harris Merger. For the quarter and two quarters ended June 28, 2019, amortization expense related to intangible assets was $27 million and $56 million, respectively, and primarily related to our acquisition of Exelis Inc. in the fourth quarter of fiscal 2015. Future estimated amortization expense for amortizable intangible assets is as follows: (In millions) Year 1 $ 441 Year 2 684 Year 3 679 Year 4 657 Year 5 611 Thereafter 3,440 Total $ 6,512

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 July 3, 2020 and January 3, 2020: July 3, 2020 January 3, 2020 Total Level 1 Level 2 Total Level 1 Level 2 (In millions) Assets Deferred compensation plan assets: (1) Equity and fixed-income securities $ 57 $ 57 $ — $ 58 $ 58 $ — Investments measured at NAV: Corporate-owned life insurance 29 29 Total fair value of deferred compensation plan assets $ 86 $ 57 $ — $ 87 $ 58 $ — Derivatives (foreign currency forward contracts) 15 — 15 10 — 10 Total assets measured at fair value $ 101 $ 57 $ 15 $ 97 $ 58 $ 10 Liabilities Deferred compensation plan liabilities: (2) Equity securities and mutual funds $ 2 $ 2 $ — $ 2 $ 2 $ — Investments measured at NAV: Common/collective trusts and guaranteed investment contracts 75 69 Total fair value of deferred compensation plan liabilities $ 77 $ 2 $ — $ 71 $ 2 $ — Derivatives (foreign currency forward contracts) 15 — 15 8 — 8 Derivatives (treasury lock contracts) 130 — 130 56 — 56 Total liabilities measured at fair value $ 222 $ 2 $ 145 $ 135 $ 2 $ 64 _______________ (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).

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): July 3, 2020 January 3, 2020 Carrying Fair Carrying Fair (In millions) Long-term debt (including current portion) (1) $ 6,939 $ 7,907 $ 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 July 3, 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 two quarters ended July 3, 2020 or in the quarter or two quarters ended June 28, 2019. In addition, no amounts were recognized in earnings in the quarter or two quarters ended July 3, 2020 or in the quarter or two quarters ended June 28, 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 intersegment 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 July 3, 2020, we had open foreign currency forward contracts with an aggregate notional amount of $572 million denominated in Canadian Dollars, British Pounds, Euros and New Zealand Dollars to hedge certain forecasted transactions. At July 3, 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 July 3, 2020 and January 3, 2020: July 3, 2020 January 3, 2020 (In millions) Derivatives designated as hedging instruments: Foreign currency forward contracts (1) Other current assets $ 11 $ 8 Other non-current assets 4 2 Other accrued items 13 6 Other long-term liabilities 2 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. During the quarter and two quarters ended July 3, 2020, we recognized a $10 million net unrealized gain and a $6 million net unrealized loss, respectively, before income taxes in other comprehensive loss from foreign currency derivatives designated as cash flow hedges. During the quarter and two quarters ended June 28, 2019, the net unrealized gain or loss recognized in other comprehensive income (loss) from foreign currency derivatives designated as cash flow hedges was not material. During the quarter and two quarters ended July 3, 2020 and the quarter and two quarters ended June 28, 2019, the net gain or loss reclassified from AOCI into earnings from foreign currency derivatives designated as cash flow hedges was not material. 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 “Engineering, selling and administrative expenses” line item in our Condensed Consolidated Statement of Income (Unaudited). At July 3, 2020, the estimated amount of existing losses to be reclassified into earnings within the next twelve months was $2 million before income taxes. Interest-Rate Risk — Cash Flow Hedges At July 3, 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, which we expect to occur before the date of maturity 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 July 3, 2020, the combined fair value of these treasury locks was a liability of $130 million, which is included in the “Other expenses and accruals” 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 July 3, 2020 and January 3, 2020, respectively. Net gains or losses from cash flow hedges recognized in earnings were not material in the quarter or two quarters ended July 3, 2020 or in the quarter or two quarters ended June 28, 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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions, except per share amounts) Net EAC adjustments, before income taxes $ 98 $ 12 $ 201 $ 18 Net EAC adjustments, net of income taxes $ 73 $ 9 $ 151 $ 13 Net EAC adjustments, net of income taxes, per diluted share $ 0.34 $ 0.07 $ 0.69 $ 0.10 Revenue recognized from performance obligations satisfied in prior periods was $102 million and $238 million for the quarter and two quarters ended July 3, 2020, respectively, and $25 million and $43 million for the quarter and two quarters ended June 28, 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 two quarters ended July 3, 2020 were impacted by reclassifications to assets and liabilities of disposal groups held for sale, a decrease in the receipt of advance payments, the timing of contractual billing milestones and the impairment loss described below. 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: July 3, 2020 January 3, 2020 (In millions) Contract assets $ 2,281 $ 2,459 Contract liabilities, current (1,106) (1,214) Contract liabilities, non-current (1) (76) (87) Net contract assets $ 1,099 $ 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: July 3, 2020 January 3, 2020 (In millions) Unbilled contract receivables, gross $ 3,890 $ 3,690 Progress payments and advances (1,609) (1,231) $ 2,281 $ 2,459 Impairment losses related to our contract assets were not material for the quarter ended July 3, 2020 or the quarter or two quarters ended June 28, 2019. In the two quarters ended July 3, 2020, we recorded impairment losses of $13 million at our Aviation Systems segment to reflect an increase in expected credit losses associated with the COVID-19-related downturn in our Commercial Aviation Solutions sector and its impact on global air traffic and customer operations. For the quarter and two quarters ended July 3, 2020, we recognized as revenue $265 million and $749 million of contract liabilities, respectively, that were outstanding at January 3, 2020. For the quarter and two quarters ended June 28, 2019, we recognized as revenue $28 million and $80 million of contract liabilities, respectively, that were outstanding at June 29, 2018. 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 July 3, 2020, our ending backlog was $19.8 billion. We expect to recognize approximately two-thirds of the revenue associated with this backlog within the next twelve months and approximately three-fourths of the revenue associated with this backlog within the next three years. 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. The historical results, discussion and presentation of our business segments as set forth in this Report reflect the impact of these 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 the quarter ended July 3, 2020, we completed the divestiture of our airport security and automation business, the operating results of which through the date of divestiture are reported as part of our Aviation Systems segment, and the divestiture of our Applied Kilovolts and Analytical Instrumentation business, the operating results of which through the date of divestiture are reported as part of our Space and Airborne Systems segment. 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. Intersegment 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 intersegment 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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue Integrated Mission Systems $ 1,331 $ 11 $ 2,701 $ 25 Space and Airborne Systems 1,249 1,019 2,441 1,975 Communication Systems 1,112 609 2,206 1,189 Aviation Systems 800 186 1,811 330 Other non-reportable business segments (1) — 44 — 79 Corporate eliminations (47) (4) (88) (5) $ 4,445 $ 1,865 $ 9,071 $ 3,593 Income From Continuing Operations Before Income Taxes Segment Operating Income (Loss): Integrated Mission Systems $ 224 $ 3 $ 425 $ 6 Space and Airborne Systems 235 195 456 369 Communication Systems 265 176 515 343 Aviation Systems 31 19 (146) 36 Other non-reportable business segments (1) — 8 — 14 Unallocated corporate expenses (2) (116) (1) (149) (1) L3Harris Merger-related transaction and integration expenses (37) (36) (68) (52) Amortization of acquisition-related intangibles (3) (208) (25) (353) (50) Pension adjustment (98) (46) (195) (93) Non-operating income 105 48 200 94 Net interest expense (65) (39) (128) (81) Total $ 336 $ 302 $ 557 $ 585 _______________ (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) Unallocated corporate expenses for the quarter and two quarters ended July 3, 2020 includes: (i) $16 million and $31 million, respectively, 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) $58 million and $61 million, respectively, of divestiture-related expenses, including a $26 million loss on sale of business, a $14 million non-cash remeasurement loss on a potential divestiture, a $12 million non-cash adjustment to the gain on sale of business and other items; (iii) a $14 million non-cash goodwill impairment charge related to a potential divestiture; and (iv) $7 million of L3Harris integration-related restructuring charges. Unallocated corporate expenses for the two quarters ended July 3, 2020 also includes a $5 million non-cash goodwill impairment charge related to the divestiture of the Applied Kilovolts and Analytical Instrumentation business. (3) Includes $183 million and $303 million of amortization of identifiable intangible assets acquired as a result of the L3Harris Merger for the quarter and two quarters ended July 3, 2020, respectively. Also includes $25 million and $50 million of amortization of identifiable intangible assets acquired as a result of our acquisition of Exelis Inc. for the quarters and two quarters ended June 28, 2019, respectively. 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 All four segments disaggregate revenue 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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship Prime contractor $ 858 $ 4 $ 1,807 $ 12 Subcontractor 473 7 894 13 $ 1,331 $ 11 $ 2,701 $ 25 Revenue By Contract Type Fixed-price (1) $ 998 $ 11 $ 2,023 $ 25 Cost-reimbursable 333 — 678 — $ 1,331 $ 11 $ 2,701 $ 25 Revenue By Geographical Region United States $ 1,038 $ 6 $ 2,143 $ 15 International 293 5 558 10 $ 1,331 $ 11 $ 2,701 $ 25 _______________ (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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship Prime contractor $ 674 $ 590 $ 1,332 $ 1,162 Subcontractor 575 429 1,109 813 $ 1,249 $ 1,019 $ 2,441 $ 1,975 Revenue By Contract Type Fixed-price (1) $ 702 $ 601 $ 1,372 $ 1,132 Cost-reimbursable 547 418 1,069 843 $ 1,249 $ 1,019 $ 2,441 $ 1,975 Revenue By Geographical Region United States $ 1,054 $ 886 $ 2,057 $ 1,732 International 195 133 384 243 $ 1,249 $ 1,019 $ 2,441 $ 1,975 _______________ (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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship (1) Prime contractor $ 749 $ 1,489 Subcontractor 363 717 $ 1,112 $ 2,206 Revenue By Contract Type (1) Fixed-price (2) $ 951 $ 1,869 Cost-reimbursable 161 337 $ 1,112 $ 2,206 Revenue by Geographical Region United States $ 844 $ 355 $ 1,678 $ 702 International 268 254 528 487 $ 1,112 $ 609 $ 2,206 $ 1,189 ______________ (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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship Prime contractor $ 514 $ 180 $ 1,178 $ 320 Subcontractor 286 6 633 10 $ 800 $ 186 $ 1,811 $ 330 Revenue By Contract Type Fixed-price (1) $ 627 $ 164 $ 1,468 $ 286 Cost-reimbursable 173 22 343 44 $ 800 $ 186 $ 1,811 $ 330 Revenue By Geographical Region United States $ 696 $ 178 $ 1,445 $ 321 International 104 8 366 9 $ 800 $ 186 $ 1,811 $ 330 ______________ (1) Includes revenue derived from time-and-materials contracts. Total assets by business segment are summarized below: July 3, 2020 January 3, 2020 (In millions) Total Assets Integrated Mission Systems $ 8,675 $ 7,896 Space and Airborne Systems 6,899 6,829 Communication Systems 5,719 5,930 Aviation Systems 5,269 7,569 Corporate (1) 11,290 10,112 $ 37,852 $ 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 $8.3 billion and $8.5 billion at July 3, 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 July 3, 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 July 3, 2020 are reserved against or would not have a material adverse effect on our financial condition, results of operations or cash flows.

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 and cash flows for the periods presented therein. The results for the quarter and two quarters ended July 3, 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. On October 12, 2018, Harris Corporation, a Delaware corporation (“Harris”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with L3 Technologies, Inc., a Delaware corporation (“L3”), 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.” (“L3Harris”), 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. Because of the L3Harris Merger, the quarter and two quarters ended July 3, 2020 reflect the results of the combined company, while the quarter and two quarters ended June 28, 2019 reflect the results of only Harris operating businesses. We accounted for the L3Harris Merger under the acquisition method of accounting. Under the acquisition method of accounting, we were required to measure identifiable assets acquired, liabilities assumed and any noncontrolling interests in the acquiree at their fair values as of the Closing Date. The excess of the consideration transferred over those fair values was recorded as goodwill. See Note B — Business Combination in these Notes for additional information related to the L3Harris Merger.
Use of Estimates	Use of EstimatesThe 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.
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 receivables 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 or cash flows.
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.
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. The historical results, discussion and presentation of our business segments as set forth in this Report reflect the impact of these 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 the quarter ended July 3, 2020, we completed the divestiture of our airport security and automation business, the operating results of which through the date of divestiture are reported as part of our Aviation Systems segment, and the divestiture of our Applied Kilovolts and Analytical Instrumentation business, the operating results of which through the date of divestiture are reported as part of our Space and Airborne Systems segment. 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. Intersegment 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 intersegment 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
Disaggregation of Revenue	Disaggregation of Revenue All four segments disaggregate revenue 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.

(2) Unallocated corporate expenses for the quarter and two quarters ended July 3, 2020 includes: (i) $16 million and $31 million, respectively, 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) $58 million and $61 million, respectively, of divestiture-related expenses, including a $26 million loss on sale of business, a $14 million non-cash remeasurement loss on a potential divestiture, a $12 million non-cash adjustment to the gain on sale of business and other items; (iii) a $14 million non-cash goodwill impairment charge related to a potential divestiture; and (iv) $7 million of L3Harris integration-related restructuring charges. Unallocated corporate expenses for the two quarters ended July 3, 2020 also includes a $5 million non-cash goodwill impairment charge related to the divestiture of the Applied Kilovolts and Analytical Instrumentation business. (3) Includes $183 million and $303 million of amortization of identifiable intangible assets acquired as a result of the L3Harris Merger for the quarter and two quarters ended July 3, 2020, respectively. Also includes $25 million and $50 million of amortization of identifiable intangible assets acquired as a result of our acquisition of Exelis Inc. for the quarters and two quarters ended June 28, 2019, respectively. 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 All four segments disaggregate revenue 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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship Prime contractor $ 858 $ 4 $ 1,807 $ 12 Subcontractor 473 7 894 13 $ 1,331 $ 11 $ 2,701 $ 25 Revenue By Contract Type Fixed-price (1) $ 998 $ 11 $ 2,023 $ 25 Cost-reimbursable 333 — 678 — $ 1,331 $ 11 $ 2,701 $ 25 Revenue By Geographical Region United States $ 1,038 $ 6 $ 2,143 $ 15 International 293 5 558 10 $ 1,331 $ 11 $ 2,701 $ 25 _______________ (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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship Prime contractor $ 674 $ 590 $ 1,332 $ 1,162 Subcontractor 575 429 1,109 813 $ 1,249 $ 1,019 $ 2,441 $ 1,975 Revenue By Contract Type Fixed-price (1) $ 702 $ 601 $ 1,372 $ 1,132 Cost-reimbursable 547 418 1,069 843 $ 1,249 $ 1,019 $ 2,441 $ 1,975 Revenue By Geographical Region United States $ 1,054 $ 886 $ 2,057 $ 1,732 International 195 133 384 243 $ 1,249 $ 1,019 $ 2,441 $ 1,975 _______________ (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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship (1) Prime contractor $ 749 $ 1,489 Subcontractor 363 717 $ 1,112 $ 2,206 Revenue By Contract Type (1) Fixed-price (2) $ 951 $ 1,869 Cost-reimbursable 161 337 $ 1,112 $ 2,206 Revenue by Geographical Region United States $ 844 $ 355 $ 1,678 $ 702 International 268 254 528 487 $ 1,112 $ 609 $ 2,206 $ 1,189 ______________ (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 Two Quarters Ended July 3, 2020 June 28, 2019 July 3, 2020 June 28, 2019 (In millions) Revenue By Customer Relationship Prime contractor $ 514 $ 180 $ 1,178 $ 320 Subcontractor 286 6 633 10 $ 800 $ 186 $ 1,811 $ 330 Revenue By Contract Type Fixed-price (1) $ 627 $ 164 $ 1,468 $ 286 Cost-reimbursable 173 22 343 44 $ 800 $ 186 $ 1,811 $ 330 Revenue By Geographical Region United States $ 696 $ 178 $ 1,445 $ 321 International 104 8 366 9 $ 800 $ 186 $ 1,811 $ 330 ______________ (1) Includes revenue derived from time-and-materials contracts.
Schedule of Total Assets by Business Segment	Total assets by business segment are summarized below: July 3, 2020 January 3, 2020 (In millions) Total Assets Integrated Mission Systems $ 8,675 $ 7,896 Space and Airborne Systems 6,899 6,829 Communication Systems 5,719 5,930 Aviation Systems 5,269 7,569 Corporate (1) 11,290 10,112 $ 37,852 $ 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 $8.3 billion and $8.5 billion at July 3, 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. See Note C — Business Divestitures and Assets Sales in these Notes for additional information.
