| SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
| Jun. 29, 2018 |
| Accounting Policies [Abstract] | |
| Principles of Consolidation | Amounts contained in this Report may not always add to totals due to rounding. Principles of Consolidation — Our Consolidated Financial Statements include the accounts of Harris Corporation and its consolidated subsidiaries. As used in these Notes to Consolidated Financial Statements (these “Notes”), the terms “Harris,” “Company,” “we,” “our” and “us” refer to Harris Corporation and its consolidated subsidiaries. Intracompany transactions and accounts have been eliminated. |
| Reclassifications | Reclassifications — The classification of certain prior-year amounts have been adjusted in our Consolidated Financial Statements to conform to current-year classifications. |
| Use of Estimates | Use of Estimates — The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires us to make estimates and assumptions that affect the amounts reported in the accompanying Consolidated Financial Statements and these Notes and related disclosures. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying Consolidated Financial Statements and these Notes. Materially different results can occur as circumstances change and additional information becomes known. |
| Fiscal Year | Fiscal Year — Our fiscal year ends on the Friday nearest June 30. Each of our fiscal years 2018 , 2017 and 2016 included 52 weeks. |
| Cash and Cash Equivalents | Cash and Cash Equivalents — Cash equivalents are temporary cash investments with a maturity of three or fewer months when purchased. These investments include accrued interest and are carried at the lower of cost or market. |
| Fair Value of Financial Instruments | Fair Value of Financial Instruments — The carrying amounts reflected in our Consolidated Balance Sheet for cash and cash equivalents, accounts receivable, non-current receivables, notes receivable, accounts payable, short-term debt and long-term variable-rate debt approximate their fair values. Fair values for long-term fixed-rate debt are primarily based on quoted market prices for those or similar instruments. |
| Fair Value Measurements | Fair Value Measurements — Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability 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 pricing service, 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. |
| Accounts Receivable | Accounts Receivable — We record receivables at net realizable value and they generally do not bear interest. This value includes an allowance for estimated uncollectible accounts to reflect any loss anticipated on the accounts receivable balances which is charged to the provision for doubtful accounts. We calculate this allowance based on our history of write-offs, level of past due accounts and economic status of the customers. We consider a receivable delinquent if it is unpaid after the term of the related invoice has expired. Write-offs are recorded at the time a customer receivable is deemed uncollectible. |
| Inventories | Inventories — Inventories are valued at the lower of cost (determined by average and first-in, first-out methods) or net realizable value. We regularly review inventory quantities on hand and record a provision for excess and obsolete inventory primarily based on our estimated forecast of product demand, anticipated end of product life and production requirements. |
| Property, Plant and Equipment | Property, Plant and Equipment — Property, plant and equipment are carried on the basis of cost and include software capitalized for internal use. Depreciation of buildings, machinery and equipment is computed by the straight-line and accelerated methods. The estimated useful lives of buildings, including leasehold improvements, generally range between 2 and 45 years. The estimated useful lives of machinery and equipment generally range between 2 and 10 years. Amortization of internal-use software begins when the software is put into service and is based on the expected useful life of the software. The useful lives over which we amortize internal-use software generally range between 3 and 10 years. |
| Goodwill | Goodwill — We follow the acquisition method of accounting to record the assets and liabilities of acquired businesses at their estimated fair value at the date of acquisition. We initially record goodwill for the amount costs exceed the acquisition-date fair value of net identifiable assets acquired. We test our goodwill for impairment annually, or under certain circumstances, more frequently, such as when events or circumstances indicate there may be impairment. Such events or circumstances may include a significant deterioration in overall economic conditions, changes in the business climate of our industry, a decline in our market capitalization, operating performance indicators, competition, reorganizations of our business or the disposal of all or a portion of a reporting unit. We test goodwill for impairment at a level within the Company referred to as the reporting unit, which is our business segment level, and, if and when applicable, one level below the business segment. We identify goodwill impairment and measure any loss from an impairment by comparing the fair value of each reporting unit to its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, goodwill is considered impaired, and an impairment loss is recognized in an amount equal to that excess |
| Long-Lived Assets, Including Finite-Lived Intangible Assets | Long-Lived Assets, Including Finite-Lived Intangible Assets — Long-lived assets, including finite-lived intangible assets, are amortized on a straight-line basis over their useful lives. We assess the recoverability of the carrying value of our long-lived assets, including finite-lived intangible assets, whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. We evaluate the recoverability of such assets based on the expectations of undiscounted cash flows from such assets. If the sum of the expected future undiscounted cash flows were less than the carrying amount of the asset, a loss would be recognized for the difference between the fair value and the carrying amount. |
| Other Assets and Liabilities | Other Assets and Liabilities — No assets within the “Other current assets” or “Other non-current assets” line items in our Consolidated Balance Sheet exceeded 5 percent of our total current assets or total assets, respectively, as of June 29, 2018 or June 30, 2017 . No accrued liabilities or expenses within the “Other accrued items” or “Other long-term liabilities” line items in our Consolidated Balance Sheet exceeded 5 percent of our total current liabilities or total liabilities, respectively, as of June 29, 2018 or June 30, 2017 . |
| Income Taxes | Income Taxes — We follow the liability method of accounting for income taxes. We record the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in our Consolidated Balance Sheet, as well as operating loss and tax credit carryforwards. We follow very specific and detailed guidelines in each tax jurisdiction regarding the recoverability of any tax assets recorded on the balance sheet and provide necessary valuation allowances as required. We regularly review our deferred tax assets for recoverability based on historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences and tax planning strategies. |
| Warranties | Warranties — On development and production contract sales in our Electronic Systems and Space and Intelligence Systems segments, the value or price of our warranty is generally included in the contract and funded by the customer. A provision for warranties is built into the estimated program costs when determining the profit rate to accrue when applying the cost-to-cost percentage-of-completion (“POC”) revenue recognition method. Warranty costs, as incurred, are charged to the specific program’s cost, and both revenue and cost are recognized at that time. Factors that affect the estimated program cost for warranties include terms of the contract, complexity of the delivered product or service, number of installed units, historical experience and management’s assumptions regarding anticipated rates of warranty claims and cost per claim. On product sales in all our segments, we provide for future standard warranty costs upon product delivery. The specific terms and conditions of those warranties vary depending on the product sold, customer and country in which we do business. In the case of products sold by us, our warranties start from the shipment, delivery or customer acceptance date and continue as follows: Segment Average Warranty Period Communication Systems One to five years Electronic Systems One to two years Space and Intelligence Systems 60 days to two years Because our products are manufactured, in many cases, to customer specifications and their acceptance is based on meeting those specifications, we historically have experienced minimal warranty costs. Factors that affect our warranty liability include the number of installed units, historical experience, anticipated delays in delivery of products to end customers, in-country support for international sales and our assumptions regarding anticipated rates of warranty claims and cost per claim. We assess the adequacy of our recorded warranty liabilities every quarter and make adjustments to the liability as necessary. |
| Foreign Currency Translation | Foreign Currency Translation — The functional currency for most international subsidiaries is the local currency. Assets and liabilities are translated at current rates of exchange and income and expense items are translated at the weighted average exchange rate for the year. The resulting translation adjustments are recorded as a separate component of shareholders’ equity. |
| Stock Options and Other Share-Based Compensation | Stock Options and Other Share-Based Compensation — We measure compensation cost for all share-based payments (including employee stock options) at fair value and recognize cost over the vesting period, with forfeitures recognized as they occur. It is our practice to issue shares when options are exercised. |
| Restructuring and Other Exit Costs | Restructuring and Other Exit Costs — We record restructuring and other exit costs 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 costs are included as a component of the “Cost of product sales and services” and “Engineering, selling and administrative expenses” line items in our Consolidated Statement of Income. 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 “Cost of product sales and services” and “Engineering, selling and administrative expenses” line items in our Consolidated Statement of Income. |
| Revenue Recognition | Revenue Recognition — Our segments have the following revenue recognition policies: Development and Production Contracts: Estimates and assumptions, and changes therein, are important in connection with, among others, our segments’ revenue recognition policies related to development and production contracts. Revenue and profits related to development and production contracts are recognized using the POC method, generally based on the ratio of costs incurred to estimated total costs at completion under the contract (i.e., the “cost-to-cost” method) with consideration given for risk of performance and estimated profit. Revenue and profits on cost-reimbursable development and production contracts are recognized as allowable costs are incurred on the contract and become billable to the customer, in an amount equal to the allowable costs plus the profit on those costs. Development and production contracts are combined when specific aggregation criteria are met. Criteria generally include closely interrelated activities performed for a single customer within the same economic environment. Development and production contracts are generally not segmented. If development and production contracts are segmented, we have determined that they meet specific segmenting criteria. Change orders, claims or other items that may change the scope of a development and production contract are included in contract value only when the value can be reliably estimated and realization is probable. Possible incentives or penalties and award fees applicable to performance on development and production contracts are considered in estimating contract value and profit rates and are recorded when there is sufficient information to assess anticipated contract performance. Incentive provisions that increase earnings based solely on a single significant event are generally not recognized until the event occurs. We are party to certain contracts with incentive provisions or award fees that are subject to uncertainty until the conclusion of the contract and our customers may be entitled to reclaim and receive previous award fee payments. Under the POC method of accounting, a single estimated total profit margin is used to recognize profit for each development and production contract over its period of performance. Recognition of profit on a development and production fixed-price contract requires estimates of the total cost at completion and the measurement of progress toward completion. The estimated profit or loss on a development and production contract is equal to the difference between the estimated contract value and the estimated total cost at completion. Due to the long-term nature of many of our programs, developing the estimated total cost at completion 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, the risk and impact of delayed performance, availability and timing of funding from the customer and the recoverability of any claims outside the original development and production contract included in the estimate to complete. 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 development and production 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, at the outset of a cost-reimbursable contract (for example, contracts containing award or incentive fees), we establish an estimate of total contract value, or revenue, based on our expectation of performance on the contract. As the cost-reimbursable contract progresses, our estimates of total contract value may increase or decrease if, for example, we receive higher or lower than expected award fees. When adjustments in estimated total costs at completion or in estimated total contract value are determined, the related impact to 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. Anticipated losses on development and production contracts or programs in progress are charged to operating income when identified. Net EAC adjustments resulting from changes in estimates favorably impacted our operating income by $2 million ( $.01 per diluted share) in fiscal 2018 , $14 million ( $8 million after-tax or $.07 per diluted share) in fiscal 2017 and $68 million ( $42 million after-tax or $.33 per diluted share) in fiscal 2016 . Products and Services Other Than Development and Production Contracts: Revenue from product sales other than development and production contracts and revenue from service arrangements are recognized when persuasive evidence of an arrangement exists, the fee is fixed or determinable, collectibility is reasonably assured, and delivery of a product has occurred and title has transferred or services have been rendered. Unearned income on service contracts is amortized by the straight-line method over the term of the contracts. Also, if contractual obligations related to customer acceptance exist, revenue is not recognized for a product or service unless these obligations are satisfied. Multiple-Element Arrangements: We have entered into arrangements other than development and production contracts that require the delivery or performance of multiple deliverables or elements under a bundled sale. These arrangements are most prevalent in our Communication Systems segment. For example, in our Communication Systems segment, in addition to delivering secure tactical radios and accessories, we may be required to perform or provide installation, design and development solutions for custom communication infrastructures, and extended warranties. For arrangements with multiple elements, judgment is required to determine the appropriate accounting, including whether the individual deliverables represent separate units of accounting for revenue recognition purposes, and the timing of revenue recognition for each deliverable. We recognize revenue for contractual deliverables as separate units of accounting when the delivered items have value to the customer on a standalone basis (i.e., if they are sold separately by any vendor or the customer could resell the delivered items on a standalone basis) and, if the arrangement includes a general right of return relative to the delivered items, we consider delivery or performance of the undelivered items as probable and substantially in our control. Deliverables that are not separable are accounted for as a combined unit of accounting, and revenue generally is recognized when persuasive evidence of an arrangement exists, the fee is fixed or determinable, collectibility is reasonably assured, and delivery of a product has occurred and title has transferred or services have been rendered. If we determine that the deliverables represent separate units of accounting, we recognize the revenue associated with each unit of accounting separately, and contract revenue is allocated among the separate units of accounting at the inception of the arrangement based on relative selling price. If options or change orders materially change the scope of work or price of the contract subsequent to inception, we reevaluate and adjust our prior conclusions regarding units of accounting and allocation of contract revenue as necessary. The allocation of selling price among the separate units of accounting may impact the timing of revenue recognition, but will not change the total revenue recognized on the arrangement. We establish the selling price used for each deliverable based on the vendor-specific objective evidence (“VSOE”) of selling price, or third-party evidence (“TPE”) of selling price if VSOE of selling price is not available, or best estimate of selling price (“BESP”) if neither VSOE nor TPE of selling price is available. In determining VSOE of selling price, a substantial majority of the recent standalone sales of the deliverable must be priced within a relatively narrow range. In determining TPE of selling price, we evaluate competitor prices for similar deliverables when sold separately. Generally, comparable pricing of our products to those of our competitors with similar functionality cannot be obtained. In determining BESP, we consider both market data and entity-specific factors, including market conditions, the geographies in which our products are sold, our competitive position and strategy, and our profit objectives. Bill-and-Hold Arrangements: Certain contracts include terms and conditions through which we recognize revenue upon completion of equipment production, which is subsequently stored at our location at the customer’s request. Revenue is recognized on such contracts upon the customer’s assumption of title and risk of ownership and when collectibility is reasonably assured. At the time of revenue recognition, there is a schedule of delivery of the product consistent with the customer’s business practices, the product has been separated from our inventory, and we do not have any remaining performance obligations such that the earnings process is not complete. Other: Net income or expense related to intellectual property matters is included as a component of the “Non-operating income (loss)” line item in our Consolidated Statement of Income and is recognized on the basis of terms specified in contractual agreements. Shipping and handling fees billed to customers are included in the “Revenue from product sales” line item in our Consolidated Statement of Income and the associated costs are included in the “Cost of product sales” line item in our Consolidated Statement of Income. Also, we record taxes collected from customers and remitted to governmental authorities on a net basis in that they are excluded from revenue. |
| Retirement and Post-Employment Benefits | Retirement and Post-Employment Benefits — Defined benefit plans that we sponsor are accounted for as defined benefit pension and other postretirement defined benefit plans (collectively referred to as “defined benefit plans”). Accordingly, the funded or unfunded position of each defined benefit plan is recorded in our Consolidated Balance Sheet. Actuarial gains and losses and prior service costs or credits that have not yet been recognized through income are recorded in the “Accumulated other comprehensive loss” line item within equity in our Consolidated Balance Sheet, net of taxes, until they are amortized as a component of net periodic benefit cost. The determination of benefit obligations and the recognition of expenses related to defined benefit plans are dependent on various assumptions. The major assumptions primarily relate to discount rates, long-term expected rates of return on plan assets, the rate of future compensation increases, mortality, termination, and healthcare cost trend rates. We develop each assumption using relevant Company experience in conjunction with market-related data. Actuarial assumptions are reviewed annually with third-party consultants and adjusted as appropriate. For the recognition of net periodic benefit cost, the calculation of the long-term expected return on plan assets is generally derived using a market-related value of plan assets based on yearly average asset values at the measurement date over the last five years, to be phased in over five years. Actual results that differ from our assumptions are accumulated and generally amortized for each plan to the extent required over the estimated future life expectancy or, if applicable, the future working lifetime of the plan’s active participants. The fair value of plan assets is determined based on market prices or estimated fair value at the measurement date. The measurement date for valuing defined benefit plan assets and obligations is the end of the month closest to our fiscal year end. Beginning in 2017, we changed the approach used to estimate the service and interest components of net periodic benefit cost of the U.S. defined benefit plans. The new estimation approach discounts the individual expected cash flows underlying the service cost and interest cost using the applicable spot rates derived from the yield curve used to discount the cash flows in determining the benefit obligation. Prior to fiscal 2017, the service and interest cost components were determined by a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. We made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows and the corresponding spot yield curve rates. We accounted for this change as a change in accounting estimate and accordingly have accounted for it prospectively. This change resulted in approximately $46 million of lower service and interest costs for our U.S. defined benefit plans in fiscal 2017 compared with the single weighted-average discount rate method. See Note 13: Pension and Other Postretirement Benefits for additional information regarding our defined benefit plans. We also provide retirement benefits to many of our U.S.-based employees through defined contribution retirement plans, including 401(k) plans and certain non-qualified deferred compensation plans. The defined contribution retirement plans have matching and savings elements. Company contributions to the retirement plans are based on employees’ savings with no other funding requirements. We may make additional contributions to the retirement plans at our discretion. Retirement and postretirement benefits also include unfunded limited healthcare plans for U.S.-based retirees and employees on long-term disability. We estimate benefits for these plans using actuarial valuations that are based in part on certain key assumptions we make, including the discount rate, the expected long-term rate of return on plan assets, the rate of future compensation increases, healthcare cost trend rates and employee turnover and mortality, each appropriately based on the nature of the plans. We accrue the cost of these benefits during an employee’s active service life, except in the case of our healthcare plans for disabled employees, the costs of which we accrue when the disabling event occurs. |
| Environmental Expenditures | Environmental Expenditures — We capitalize environmental expenditures that increase the life or efficiency of property or that reduce or prevent environmental contamination. We accrue environmental expenses resulting from existing conditions that relate to past or current operations. Our accruals for environmental expenses are recorded on a site-by-site basis when it is probable a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies available to us. Our accruals for environmental expenses represent the best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees, and are reviewed periodically, at least annually at the year-end balance sheet date, and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. If the timing and amount of future cash payments for environmental liabilities are fixed or reliably determinable, we generally discount such cash flows in estimating our accrual. As of June 29, 2018 , we were named, and continue to be named, as a potentially responsible party at 60 sites where future liabilities could exist. These sites included 5 sites owned by us, 46 sites associated with our former locations or operations and 9 hazardous waste treatment, storage or disposal facility sites not owned by us that contain hazardous substances allegedly attributable to us from past operations. Based on an assessment of relevant factors, we estimated that our liability under applicable environmental statutes and regulations for identified sites was approximately $103 million , consisting of approximately $97 million for environmental liabilities related to Exelis operations and approximately $6 million for other environmental liabilities. In each case, the current portion of our estimated environmental liability is included in the “Other accrued items” line item and the non-current portion is included in the “Other long-term liabilities” line item in our Consolidated Balance Sheet. The relevant factors we considered in estimating our potential liabilities under applicable environmental statutes and regulations included some or all of the following as to each site: incomplete information regarding particular sites and other potentially responsible parties; uncertainty regarding the extent of investigation or remediation; our share, if any, of liability for such conditions; the selection of alternative remedial approaches; changes in environmental standards and regulatory requirements; potential insurance proceeds; cost-sharing agreements with other parties and potential indemnification from successor and predecessor owners of these sites. We do not believe that any uncertainties regarding these relevant factors will materially affect our potential liability under applicable environmental statutes and regulations. We believe the total amount accrued is appropriate based on existing facts and circumstances, although we note the total amount accrued may increase or decrease in future years. |
| Financial Guarantees and Commercial Commitments | Financial Guarantees and Commercial Commitments — Financial guarantees are contingent commitments issued to guarantee the performance of a customer to a third party in borrowing arrangements, such as commercial paper issuances, bond financings and similar transactions. As of June 29, 2018 , we did not have material financial guarantees and there were no such contingent commitments accrued for in our Consolidated Balance Sheet. We have entered into commercial commitments in the normal course of business including surety bonds, standby letter of credit agreements and other arrangements with financial institutions and customers primarily relating to the guarantee of future performance on certain contracts to provide products and services to customers and to obtain insurance policies with our insurance carriers. |
| Financial Instruments and Risk Management | Financial Instruments and Risk Management — In the normal course of business, we are exposed to global market risks, including the effect of changes in foreign currency exchange 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 may also enter into derivative instruments that are not designated as hedges and do not qualify for hedge accounting. We recognize all derivatives in our Consolidated Balance Sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of assets, liabilities or firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative’s change in fair value is immediately recognized in earnings. We do not hold or issue derivatives for speculative trading purposes. |
| Income From Continuing Operations Per Share | Income From Continuing Operations Per Share — For all periods presented in our Consolidated Financial Statements and these Notes, income from continuing operations per share is computed using the two-class method. The two-class method of computing income from continuing operations per share is an earnings allocation formula that determines income from continuing operations per share for common stock and any participating securities according to dividends paid and participation rights in undistributed earnings. Our restricted stock awards and restricted stock unit awards generally meet the definition of participating securities and are included in the computations of income from continuing operations per basic and diluted common share. Our performance share awards and performance share unit awards do not meet the definition of participating securities because they do not contain rights to receive nonforfeitable dividends and, therefore, are excluded from the computations of income from continuing operations per basic and diluted common share. Under the two-class method, income from continuing operations per common share is computed by dividing the sum of earnings distributed to common shareholders and undistributed earnings allocated to common shareholders by the weighted-average number of common shares outstanding for the period. Income from continuing operations per diluted common share is computed using the more dilutive of the two-class method or the treasury stock method. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted-average shares outstanding during the period. |
| Business Segments | Business Segments — 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 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 recognizes a profit that is eliminated. The “Corporate eliminations” line items in Note 22: Business Segments represent the elimination of intersegment sales. The “Unallocated corporate expense and corporate eliminations” line item in Note 22: Business Segments represents the portion of corporate expenses not allocated to our business segments and elimination of intersegment profits. We structure our operations primarily around the products, systems and services we sell and the markets we serve, and we report the financial results of our continuing operations in the following three reportable segments, which are also referred to as our business segments: • Communication Systems, serving markets in tactical communications and defense products, including tactical ground and airborne radio communications solutions and night vision technology, and in public safety networks; • Electronic Systems, providing electronic warfare, avionics, and command, control, communications, computers, intelligence, surveillance and reconnaissance solutions for defense and classified customers and mission-critical communication systems for civil and military aviation and other customers; and • Space and Intelligence Systems, providing intelligence, space protection, geospatial, complete Earth observation, universe exploration, positioning, navigation and timing, and environmental solutions for national security, defense, civil and commercial customers, using advanced sensors, antennas and payloads, as well as ground processing and information analytics. |
| Adoption of New Accounting Standards and Accounting Standards Issued But Not Yet Effective | Adoption of New Accounting Standards In the first quarter of fiscal 2018, we adopted an accounting standards update issued by the Financial Accounting Standards Board (“FASB”) that requires recognition of the income tax consequences of intra-entity transfers of assets other than inventory when the transfer occurs. Consequently, this update eliminates the exception to the recognition of current and deferred income taxes for intra-entity transfers of assets other than for inventory until the assets have been sold to an outside party. This update requires entities to apply a modified retrospective approach with a cumulative catch-up adjustment to beginning retained earnings in the period of adoption. In addition, entities are required to record deferred tax balances with an offset to retained earnings for unrecognized amounts that will be recognized under this update. We applied all changes required by this update using the modified retrospective approach from the beginning of fiscal 2018. Adopting this update resulted in a $27 million reduction of prepaid income tax assets from the “Other current assets” and “Other non-current assets” line items and a $27 million increase in the “Non-current deferred income taxes” line item in our Condensed Consolidated Balance Sheet (Unaudited) as of September 29, 2017. In the fourth quarter of fiscal 2018, we adopted an accounting standards update issued by the FASB that allows companies to reclassify the stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), from accumulated other comprehensive loss to retained earnings. Stranded tax effects are the deferred tax amounts recorded through other comprehensive income, using a 35% statutory rate, that remained after we remeasured our net deferred tax assets and liabilities to reflect the lower enacted corporate tax rates. We elected to early adopt this accounting standards update and elected to reclassify, in the period of enactment, stranded tax effects totaling $35 million from the “Accumulated other comprehensive loss” line item to the “Retained earnings” line item in our Consolidated Balance Sheet. The reclassification amount primarily included income tax effects related to our pension and postretirement benefit plans. Income tax effects remaining in accumulated other comprehensive income will be released into earnings as the related pretax amounts are reclassified to earnings. Accounting Standards Issued But Not Yet Effective In May 2014, the FASB issued a comprehensive new revenue recognition standard that supersedes nearly all revenue recognition guidance under GAAP and supersedes some cost guidance for construction-type and production-type contracts. The guidance in this standard is principles-based and, consequently, entities will be required to use more judgment and make more estimates than under prior guidance, including identifying contract performance obligations, estimating variable consideration to include in the contract price and allocating the transaction price to separate performance obligations. The core principle of this standard is that entities should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. To help financial statement users better understand the nature, amount, timing and potential uncertainty of the revenue that is recognized, this standard requires significantly more interim and annual disclosures. We adopted the new standard in fiscal 2019 using the full retrospective method, whereby the guidance in the new standard will be applied to each prior fiscal year presented and the cumulative effect of applying the guidance in the new standard will be recognized at the beginning of fiscal 2017. In preparation for the adoption of this standard, we formed a project team to assess customer contracts across our business segments and have periodically briefed our Audit Committee on the progress of our assessment. We designed and implemented controls over our assessment, including our calculation of the cumulative effect of adoption. We have also updated our accounting policies, redesigned certain business processes and systems, determined the extent of the expanded disclosure requirements and changed internal controls over financial reporting in connection with adopting the new standard. We have completed our preliminary assessment of the impact of adopting the new standard, and the following table presents adjusted and as reported selected financial data: AS ADJUSTED (PRELIMINARY) AS REPORTED 2018 2017 2018 2017 (In millions) Revenue from product sales and services $ 6,171 $ 5,897 $ 6,182 $ 5,900 Operating income $ 1,110 $ 1,066 $ 1,122 $ 1,073 Although the adjusted selected results of operations presented above may not be indicative of our future results of operations, we do not expect the new standard to have a material impact on our financial condition, results of operations or cash flows after the period of adoption. In March 2017, the FASB issued an accounting standards update to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. This update requires that entities present components of net periodic pension cost and net periodic postretirement benefit cost other than the service cost component separately from the service cost component and outside the subtotal of income from operations. We will adopt the new standard in fiscal 2019, whereby the new guidance will be applied retrospectively to each prior fiscal year presented. Adopting this accounting standard will result in a decrease in operating income and an increase in the net non-operating components of income from continuing operations of $186 million , $184 million and $164 million for fiscal 2019, 2018 and 2017, respectively. Adopting this accounting standard will not have a material impact on our financial condition or cash flows. In February 2016, the FASB issued a new lease standard that supersedes existing lease guidance under GAAP. This standard requires, among other things, the recognition of right-of-use (“ROU”) assets and liabilities on the balance sheet for all leases longer than 12 months and disclosure of certain information about leasing arrangements. The standard currently allows two transition methods whereby companies may elect to use the modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, with certain practical expedients available, or to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. This standard is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2018, which for us is our fiscal 2020. We continue to evaluate the impact this standard will have on our financial condition, results of operations and cash flows, which could be material, and we have not yet made a decision on the adoption method, as this determination is primarily dependent on the completion of our analysis |
| Stock Options | Stock Options The following information relates to stock options, including performance stock options, that have been granted under shareholder-approved SIPs. Option exercise prices are equal to or greater than the fair market value of our common stock on the date the options are granted, using the closing stock price of our common stock. Options may be exercised for a period of ten years after the date of grant, and options, other than performance stock options, generally become exercisable in installments, which are typically 33.3 percent one year from the grant date, 33.3 percent two years from the grant date and 33.3 percent three years from the grant date. In certain instances, vesting and exercisability are also subject to performance criteria. The fair value as of the grant date of each option award was determined using the Black-Scholes-Merton option-pricing model which uses assumptions noted in the following table. Expected volatility over the expected term of the options is based on implied volatility from traded options on our common stock and the historical volatility of our stock price. The expected term of the options is based on historical observations of our common stock, considering average years to exercise for all options exercised and average years to cancellation for all options canceled, as well as average years remaining for vested outstanding options, which is calculated based on the weighted-average of these three inputs. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. |
| Restricted Stock and Restricted Stock Unit Awards | Restricted Stock and Restricted Stock Unit Awards The following information relates to awards of restricted stock and restricted stock units that have been granted to employees under our SIPs. These awards are not transferable until vested and the restrictions generally lapse upon the achievement of continued employment over a specified time period. The fair value as of the grant date of these awards was based on the closing price of our common stock on the grant date and is amortized to compensation expense over the vesting period. At June 29, 2018 , there were 25,902 shares of restricted stock and 388,788 restricted stock units outstanding which were payable in shares. |
| Performance Share and Performance Share Unit Awards | Performance Share Unit Awards The following information relates to awards of performance share units that have been granted to employees under our SIPs. Generally, these awards are subject to performance criteria, such as meeting predetermined operating income or earnings per share and return on invested capital targets (and market conditions, such as total shareholder return (“TSR”)) for a 3 -year performance period. These awards also generally vest at the expiration of the same 3 -year period. The final determination of the number of shares to be issued in respect of an award is made by our Board of Directors or a committee of our Board of Directors. The fair value as of the grant date of these awards was determined based on a fair value from a multifactor Monte Carlo valuation model that simulates our stock price and TSR relative to other companies in our TSR peer group, less a discount to reflect the delay in payments of cash dividend-equivalents that are made only upon vesting. The fair value of these awards is amortized to compensation expense over the vesting period if achievement of the performance measures is considered probable. At June 29, 2018 , there were 625,293 performance share units outstanding which were payable in shares. |
