| Significant Accounting Policies and Recent Accounting Standards                | NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)Significant Accounting Policies and Recent Accounting StandardsBasis of PresentationThe accompanying condensed consolidated financial statements include the accounts of Harris Corporation and its consolidated subsidiaries. As used in these Notes to Condensed Consolidated Financial Statements (Unaudited) (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 in consolidation. The accompanying condensed consolidated financial statements have been prepared by Harris, 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 position, results of operations and cash flows 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 position, results of operations and cash flows for the periods presented therein. The results for the third quarter and first three quarters of fiscal 2016 are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. The balance sheet at July 3, 2015 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 Annual Report on Form 10-K, 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 Annual Report on Form 10-K for the fiscal year ended July 3, 2015 (our “Fiscal 2015 Form 10-K”).As further discussed in Note B — Discontinued Operations and Divestitures in these Notes, we recorded a loss in discontinued operations in the second quarter of fiscal 2016 based on a final determination rendered in a dispute over the amount of the post-closing working capital adjustment to the purchase price for our former broadcast communications operation (“Broadcast Communications”), which we sold on February 4, 2013. We did not restate our historical financial results of operations to account for Broadcast Communications as discontinued operations for the periods prior to the second quarter of fiscal 2016 presented in this Report because the amounts were not material. Unless otherwise specified, disclosures in these Notes relate solely to our continuing operations.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 and these Notes. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying condensed consolidated financial statements and these Notes. Materially different results can occur as circumstances change and additional information becomes known.ReclassificationsCertain prior year amounts have been reclassified in our Condensed Consolidated Financial Statements (Unaudited) to conform to current year classifications.Adoption of New Accounting StandardsIn the first quarter of fiscal 2016, we adopted an accounting standard issued by the Financial Accounting Standards Board (“FASB”) that eliminates the requirement for an acquirer in a business combination to retrospectively account for measurement-period adjustments. Instead, the new guidance requires that the cumulative impact of a measurement-period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified. This standard is to be applied prospectively. The adoption of this standard did not have a material impact on our financial position, results of operations or cash flows.In the second quarter of fiscal 2016, we adopted an accounting standard issued by the FASB that simplifies the presentation of deferred income taxes by requiring entities to classify all deferred tax assets and liabilities as non-current in a classified statement of financial position instead of separating deferred tax assets and liabilities into current and non-current amounts. Consequently, entities may no longer allocate valuation allowances between current and non-current deferred tax assets because those allowances also will be classified as non-current. This standard was applied retrospectively, and as a result, we reclassified certain prior-period amounts in the accompanying Condensed Consolidated Financial Statements (Unaudited) to conform with current-period classifications as follows:•In the accompanying Condensed Consolidated Balance Sheet (Unaudited), we reclassified $341 million  of current deferred income tax assets from the “Current deferred income taxes” line item in the assets section and $7 million of current deferred income tax liabilities from the "Current deferred income taxes" line item in the liabilities and equity section, which resulted in an increase of $339 million to the “Non-current deferred income taxes” line item in the assets section and a net increase of $5 million to the "Non-current deferred income taxes" line item in the liabilities and equity section.•In the accompanying Condensed Consolidated Statement of Cash Flows (Unaudited), we reclassified $20 million from the “Non-current deferred income taxes” line item to the “Income taxes” line item in the operating activities section.Other than those reclassifications, the adoption of this standard did not have any impact on our financial position, results of operations or cash flows.Accounting Standards Issued But Not Yet EffectiveIn May 2014, the FASB issued a comprehensive new revenue recognition standard that supersedes nearly all revenue recognition guidance under GAAP and International Financial Reporting Standards 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 guidance in this standard is applicable to all contracts with customers, regardless of industry-specific or transaction-specific fact patterns. Additionally, this standard provides guidance for transactions that were not previously addressed comprehensively (e.g., service revenue, contract modifications and licenses of intellectual property) and modifies guidance for multiple-element arrangements. 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. This standard allows for either “full retrospective” adoption (application to all periods presented) or “modified retrospective” adoption (application to only the most current period presented in the financial statements, as well as certain additional required footnote disclosures). In August 2015, the FASB issued an accounting standards update that defers the effective date of this standard by one year, while permitting entities to elect to adopt one year earlier on the original effective date. As a result, this standard is now effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017, which for us is our fiscal 2019. In March 2016 and April 2016, the FASB issued two accounting standards updates that clarify its new revenue recognition guidance on accounting for licenses of intellectual property and identifying performance obligations as well as principal versus agent guidance. We are currently evaluating the impact the new revenue recognition standard will have on our financial position, results of operations and cash flows.In February 2016, the FASB issued a new lease standard that supersedes existing lease guidance under GAAP. This standard requires lessees to record most leases on their balance sheets but recognize expenses on their income statements in a manner similar to existing lease guidance under GAAP. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, with the option to use certain relief. Full retrospective application is prohibited. 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 are currently evaluating the impact this standard will have on our financial position, results of operations and cash flows. In March 2016, the FASB issued an accounting standards update making final targeted amendments to the accounting for employee share-based payments. These amendments will require entities to recognize the income tax effects of awards when the awards vest or are settled, will change an employer's accounting for an employee's use of shares to satisfy the employer's statutory income tax withholding obligation and will require entities to elect whether to account for forfeitures of share-based payments by either recognizing forfeitures of awards as they occur or estimating the number of awards expected to be forfeited as is currently required. The required method of adoption varies by amendment. This accounting standards update is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2016, which for us is our fiscal 2018. Early adoption is permitted in any annual or interim period, but all of the guidance is required to be adopted in the same period and any adjustments must be reflected as of the beginning of the fiscal year. We are currently evaluating the impact this accounting standards update will have on our financial position, results of operations and cash flows. |
