Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated balance sheet at March 26, 2017, the consolidated statements of (loss) income for the three and nine months ended March 26, 2017 and March 27, 2016, the consolidated statements of comprehensive (loss) income for the three and nine months ended March 26, 2017 and March 27, 2016, and the consolidated statements of cash flows for the nine months ended March 26, 2017 and March 27, 2016 (collectively, the consolidated financial statements) have been prepared by the Company and have not been audited. In the opinion of management, all normal and recurring adjustments necessary to fairly state the consolidated financial position, results of operations, comprehensive income and cash flows at March 26, 2017, and for all periods presented, have been made. All intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 26, 2016 has been derived from the audited financial statements as of that date. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 26, 2016 (fiscal 2016). The results of operations for the three and nine months ended March 26, 2017 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 25, 2017 (fiscal 2017). The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates. Certain fiscal 2016 amounts in the accompanying consolidated financial statements have been reclassified to conform to the fiscal 2017 presentation. These reclassifications had no effect on previously reported consolidated net income or shareholders’ equity.
Comparability of Prior Period Financial Data
New Accounting Standards	Recently Issued Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09: Revenue from Contracts with Customers (Topic 606). The FASB has subsequently issued multiple ASUs which amend and clarify the guidance in Topic 606. The ASU establishes a principles-based approach for accounting for revenue arising from contracts with customers and supersedes existing revenue recognition guidance. The ASU provides that an entity should apply a five-step approach for recognizing revenue, including (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. Also, the entity must provide various disclosures concerning the nature, amount and timing of revenue and cash flows arising from contracts with customers. The effective date will be the first quarter of the Company's fiscal year ending June 30, 2019, using one of two retrospective application methods. The Company is currently analyzing the impact of this new pronouncement. Leases In February 2016, the FASB issued ASU No. 2016-02: Leases (Topic 842). The ASU requires that a lessee recognize in its statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. For income statement purposes, leases are still required to be classified as either operating or finance. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. The effective date will be the first quarter of the Company's fiscal year ending June 28, 2020, using a modified retrospective approach. The Company is currently analyzing the impact of this new pronouncement. Stock Compensation In March 2016, the FASB issued ASU No. 2016-09: Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The ASU simplifies the current stock compensation guidance for tax consequences. The ASU requires an entity to recognize all excess tax benefits and tax deficiencies as income tax expense or benefit in its income statement. The ASU also eliminates the requirement to defer recognition of an excess tax benefit until the benefit is realized through a reduction to taxes payable. For cash flows statement purposes, excess tax benefits should be classified as an operating activity and cash payments made to taxing authorities on the employee’s behalf for withheld shares should be classified as financing activity. The effective date will be the first quarter of the Company's fiscal year ending June 30, 2018. The Company is currently analyzing the impact of this new pronouncement. Goodwill Impairment Testing In January 2017, the FASB issued ASU No. 2017-04: Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU simplifies the manner in which an entity is required to test for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Additionally, the ASU removes the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails such qualitative test, to perform Step 2 of the goodwill impairment test. The effective date will be the first quarter of the Company's fiscal year ending June 27, 2021. The Company’s adoption of this guidance is not expected to have a significant impact on its consolidated financial statements.
Stock-Based Compensation Valuation and Expense	Stock-Based Compensation Valuation and Expense The Company accounts for its employee stock-based compensation plans using the fair value method. The fair value method requires the Company to estimate the grant-date fair value of its stock-based awards and amortize this fair value to compensation expense over the requisite service period or vesting term. The Company uses the Black-Scholes option-pricing model to estimate the fair value of the Company’s stock option and ESPP awards. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. Due to the inherent limitations of option-valuation models, future events that are unpredictable and the estimation process utilized in determining the valuation of the stock-based awards, the ultimate value realized by award holders may vary significantly from the amounts expensed in the Company’s financial statements. For RSAs and RSUs, the grant-date fair value is based upon the market price of the Company’s common stock on the date of the grant. This fair value is then amortized to compensation expense over the requisite service period or vesting term. Stock-based compensation expense is recognized net of estimated forfeitures such that expense is recognized only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates.
Financial Results by Reportable Segment	Financial Results by Reportable Segment The table below reflects the results of the Company's reportable segments as reviewed by the Chief Operating Decision Maker (CODM) for the three and nine months ended March 26, 2017 and March 27, 2016. The Company's CODM is the Chief Executive Officer. The Company used the same accounting policies to derive the segment results reported below as those used in the Company's consolidated financial statements. The Company's CODM does not review inter-segment transactions when evaluating segment performance and allocating resources to each segment, and inter-segment transactions are not included in the segment revenue presented in the table below. As such, total segment revenue in the table below is equal to the Company's consolidated revenue. The Company's CODM reviews gross profit as the lowest and only level of segment profit. As such, all items below gross profit in the consolidated statements of (loss) income must be included to reconcile the consolidated gross profit presented in the table below to the Company's consolidated loss from continuing operations before income taxes. In order to determine gross profit for each reportable segment, the Company allocates direct costs and indirect costs to each segment's cost of revenue. The Company allocates indirect costs, such as employee benefits for manufacturing employees, shared facilities services, information technology, purchasing, and customer service, when the costs are identifiable and beneficial to the reportable segment. The Company allocates these indirect costs based on a reasonable measure of utilization that considers the specific facts and circumstances of the costs being allocated. Unallocated costs in the table below consisted primarily of manufacturing employees’ stock-based compensation, expenses for profit sharing and quarterly or annual incentive plans and matching contributions under the Company’s 401(k) plan. These costs were not allocated to the reportable segments’ gross profit because the Company’s CODM does not review them regularly when evaluating segment performance and allocating resources.
