The Company and Basis of Presentation (Policies)	6 Months Ended
The Company and Basis of Presentation (Policies)	Dec. 29, 2017
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the statements do not include all information and footnotes required by U.S. GAAP for annual consolidated financial statements. In the opinion of our management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows for such periods. The results for the three and six months ended December 29, 2017 are not necessarily indicative of the results that may be expected for the full fiscal year or future operating periods. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. All intercompany transactions and accounts have been eliminated. Certain amounts in the consolidated financial statements of the prior period have been reclassified to conform to the presentation for the current period. We operate on a 52-week or 53-week year ending on the Friday closest to June 30. The first two quarters of fiscal 2018 and fiscal 2017 included 13 weeks in each quarter.
Use of Estimates	Use of Estimates The preparation of unaudited condensed consolidated financial statements in accordance with U.S. GAAP requires us to make estimates, assumptions and judgments affecting the amounts reported and related disclosures. Estimates are based upon historical factors, current circumstances and the experience and judgment of our management. We evaluate our estimates and assumptions on an ongoing basis and may employ outside experts to assist us in making these evaluations. Changes in such estimates, based on more accurate information, or different assumptions or conditions, may affect amounts reported in future periods. Such estimates affect significant items, including revenue recognition, provision for uncollectible receivables, inventory valuation, valuation allowances for deferred tax assets, uncertainties in income taxes, restructuring obligations, product warranty obligations, share-based awards, contingencies, recoverability of long-lived assets and useful lives of property, plant and equipment.
Recently Issued Accounting Standards	Accounting Standards Adopted In October 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-16 (Topic 740), Accounting for Income Taxes: Intra-Entity Transfers of Assets Other than Inventory, which requires that an entity recognizes the tax expense from the sale of intra-entity sales of assets, other than inventory, in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminate in consolidation. We adopted this update during the first quarter of fiscal 2018. The adoption had no material impact on our unaudited condensed consolidated financial statements. In July 2015, the FASB issued ASU 2015-11 (Topic 330), Simplifying the Measurement of Inventory, which provides guidance to companies who account for inventory using either the first-in, first-out or average cost methods. The guidance states that companies should measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. We adopted this update prospectively during the first quarter of fiscal 2018. The adoption had no material impact on our unaudited condensed consolidated financial statements. Accounting Standards Not Yet Adopted In May 2014, the FASB issued ASU 2014-09 (ASC Topic 606), Revenue from Contracts with Customers with amendments issued in 2015 and 2016. This standard update will supersede nearly all current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. Revenue recognition will 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 or services. Additional disclosures will also be required to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized in retained earnings as of the date of adoption. We are on schedule in establishing new accounting policies, implementing systems and processes (including more extensive use of estimates), and internal controls necessary to support the requirements of the new standard. We have completed our preliminary assessment of the financial statement impact of the new standard and will continue to update that assessment as more information becomes available. We expect the timing of revenue recognition to change in certain areas, including our services segment’s installation revenue, which upon adoption will be recognized as revenue and costs over a period of time. The performance obligations of certain arrangements are expected to be satisfied at the time of title transfer and risk of loss to the customer which is generally upon shipment, rather than at customer acceptance. Additionally, the analysis of our contracts under the new revenue recognition standard supports the recognition of revenue over time under the cost-to-cost method for some of our contracts, which is consistent with our current revenue recognition model. Revenue on these contracts will continue to be recognized over time because of the continuous transfer of control to the customer. Under the new standard, the cost-to-cost measure of progress continues to best depict the transfer of control of assets to the customer, which occurs as we incur costs. In addition, the number of our performance obligations within our financial accounting and reporting model under the existing standard is not expected to be materially different under the new standard. This preliminary assessment is based on the types and number of revenue arrangements currently in place. The exact impact of the new standard will be dependent on facts and circumstances at adoption and could vary from quarter to quarter. We currently expense sales commissions as incurred, and the requirement in the new standard is to capitalize certain in-scope sales commissions. This requirement is being evaluated to determine its potential impact on our financial statements in the year of adoption. We expect to adopt the new standard on a modified retrospective basis in the first quarter of fiscal 2019. We are continuing to assess all potential impacts of the guidance on our unaudited condensed consolidated financial statements and given normal ongoing business dynamics, preliminary conclusions are subject to change. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. This standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. We expect that most of our operating lease commitments will be subject to the new standard and recognized as right-of-use assets and operating lease liabilities upon the adoption of ASU 2016-02. We are evaluating the effect the adoption of the standard will have on our unaudited condensed consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance retains the current accounting for classifying and measuring investments in debt securities and loans, but requires equity investments to be measured at fair value with subsequent changes recognized in net income, except for those accounted for under the equity method or requiring consolidation. The guidance also changes the accounting for investments without a readily determinable fair value and do not qualify for the practical expedient to estimate fair value. A policy election can be made for these investments whereby estimated fair value may be measured at cost and adjusted in subsequent periods for any impairment or changes in observable prices of identical or similar investments. This ASU is effective for fiscal years beginning after December 15, 2017. We do not expect the adoption of this standard to have a material impact on our unaudited condensed consolidated financial statements.
