Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and New Accounting Standards	Basis of Presentation and New Accounting Standards Overview Cree, Inc. (the Company) is a leading innovator of lighting-class light emitting diode (LED) products, lighting products and wide bandgap semiconductor products for power and radio-frequency (RF) applications. The Company's products are targeted for applications such as indoor and outdoor lighting, video displays, transportation, electronic signs and signals, power supplies, inverters and wireless systems. The Company's lighting products primarily consist of LED lighting systems and bulbs. The Company designs, manufactures and sells lighting fixtures and lamps for the commercial, industrial and consumer markets. The Company's LED products consist of LED components, LED chips and silicon carbide (SiC) materials. The Company's success in selling LED products depends upon its ability to offer innovative products and to enable its customers to develop and market LED-based products that successfully compete against other LED-based products and drive LED adoption against traditional lighting products. In addition, the Company develops, manufactures and sells power and RF devices based on wide bandgap semiconductor materials such as SiC and gallium nitride (GaN). As previously announced, the Company has filed a confidential registration statement for an initial public offering to take this business public under the name Wolfspeed, Inc. The Company's power products are made from SiC and provide increased efficiency, faster switching speeds and reduced system size and weight over comparable silicon-based power devices. The Company's RF devices are made from GaN and provide improved efficiency, bandwidth and frequency of operation as compared to silicon or gallium arsenide (GaAs). The majority of the Company's products are manufactured at its production facilities located in North Carolina, Wisconsin and China. The Company also uses contract manufacturers for certain products and aspects of product fabrication, assembly and packaging. The Company operates research and development facilities in North Carolina, California, Wisconsin, India and China (including Hong Kong). Cree, Inc. is a North Carolina corporation established in 1987 and is headquartered in Durham, North Carolina. The Company's three reportable segments are: • Lighting Products • LED Products • Power and RF Products For financial results by reportable segment, please refer to Note 13, "Reportable Segments." Basis of Presentation The consolidated balance sheet at December 27, 2015 , the consolidated statements of income (loss) for the three and six months ended December 27, 2015 and December 28, 2014 , the consolidated statements of comprehensive income (loss) for the three and six months ended December 27, 2015 and December 28, 2014 , and the consolidated statements of cash flows for the six months ended December 27, 2015 and December 28, 2014 (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 and cash flows at December 27, 2015 , and for all periods presented, have been made. All intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 28, 2015 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 28, 2015 (fiscal 2015 ). The results of operations for the three and six months ended December 27, 2015 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 26, 2016 (fiscal 2016 ). 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 2015 amounts in the accompanying consolidated financial statements have been reclassified to conform to the fiscal 2016 presentation. These reclassifications had no effect on previously reported consolidated net income or shareholders’ equity. 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 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 accounting guidance. Income Taxes In November 2015, the FASB issued ASU No. 2015-17: Income Taxes (Topic 740). The ASU requires entities to present deferred tax assets and deferred tax liabilities as noncurrent in a classified balance sheet. The ASU simplifies the current guidance, which requires entities to separately present deferred tax assets and deferred tax liabilities as current or noncurrent in a classified balance sheet. The ASU is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early application of the ASU is permitted as of the beginning of an interim or annual reporting period and may be applied either prospectively or retrospectively to all periods presented. The Company has adopted the provisions of this ASU prospectively for the interim period ended December 27, 2015 and therefore, prior periods were not retrospectively adjusted. The Company’s adoption of the new accounting guidance did not have a significant impact on its consolidated financial statements.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Acquisition On July 8, 2015, the Company closed on the acquisition of Arkansas Power Electronics International, Inc. (APEI), a global leader in power modules and power electronics applications, pursuant to a merger agreement with APEI and certain shareholders of APEI, whereby the Company acquired all of the outstanding share capital of APEI in exchange for a base purchase price of $13.8 million , subject to certain adjustments. In addition, if certain goals are achieved over the next two years, additional cash payments totaling up to $4.6 million may be made to the former APEI shareholders. In connection with this acquisition, APEI became a wholly owned subsidiary of the Company, renamed Cree Fayetteville, Inc. (Cree Fayetteville). Cree Fayetteville will not be considered a significant subsidiary of the Company and its results from operations will be reported as part of the Company's Power and RF Products segment. The total estimated purchase price for this acquisition is as follows (in thousands): Cash consideration paid to shareholders $13,797 Post-closing adjustments 181 Contingent consideration 4,625 Total purchase price $18,603 The purchase price for this acquisition has been allocated to the assets acquired and liabilities assumed based on their estimated fair values as follows (in thousands): Tangible assets: Cash and cash equivalents $1,284 Accounts receivable 1,006 Inventories 143 Property and equipment 935 Other assets 270 Total tangible assets 3,638 Intangible assets: Patents 40 Customer relationships 4,500 Developed technology 11,403 In-process research and development 7,565 Non-compete agreements 231 Goodwill 2,483 Total intangible assets 26,222 Liabilities assumed: Accounts payable 55 Accrued expenses and liabilities 1,911 Other long-term liabilities 9,291 Total liabilities assumed 11,257 Net assets acquired $18,603 The identifiable intangible assets acquired as a result of the acquisition will be amortized over their respective estimated useful lives as follows (in thousands, except for years): Asset Amount Estimated Life in Years Patents $40 20 Customer relationships 4,500 4 Developed technology 11,403 10 In-process research and development 1 7,565 - Non-compete agreements 231 3 Total identifiable intangible assets $23,739 (1) In-process research and development (IPR&D) is initially classified as indefinite-lived assets and tested for impairment at least annually or when indications of potential impairment exist. When an IPR&D project is complete, it is reclassified as an amortizable intangible asset and amortized over its estimated useful life. Goodwill largely consists of expansion of product offerings of power modules and power electronics applications, manufacturing and other synergies of the combined companies, and the value of the assembled workforce. The assets, liabilities, and operating results of APEI have been included in the Company's consolidated financial statements from the date of acquisition and are not significant to the Company as a whole.

Realized gains and losses from the sale of investments are included in Non-operating income (loss), net in the Consolidated Statements of Income (Loss) and unrealized gains and losses are included as a separate component of equity, net of tax, unless the loss is determined to be other-than-temporary. The Company evaluates its investments for possible impairment or a decline in fair value below cost basis that is deemed to be other-than-temporary on a periodic basis. It considers such factors as the length of time and extent to which the fair value has been below the cost basis, the financial condition of the investee, and its ability and intent to hold the investment for a period of time that may be sufficient for an anticipated full recovery in market value. Accordingly, the Company considered declines in its investments to be temporary in nature, and did not consider its securities to be impaired as of December 27, 2015 and June 28, 2015 . The contractual maturities of short-term investments as of December 27, 2015 were as follows (in thousands): Within One Year After One, Within Five Years After Five, Within Ten Years After Ten Years Total Municipal bonds $17,190 $143,765 $33,176 $— $194,131 Corporate bonds 33,343 95,596 34,516 — 163,455 U.S. certificates of deposit — 500 — — 500 Non-U.S. certificates of deposit 168,481 — — — 168,481 Total short-term investments $219,014 $239,861 $67,692 $— $526,567

Fair Value of Financial Instrum

Fair Value of Financial Instruments	6 Months Ended
	Dec. 27, 2015
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the exit price) in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches, including quoted market prices and discounted cash flows. U.S. GAAP also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability. The fair value hierarchy is categorized into three levels based on the reliability of inputs as follows: • Level 1 - Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. • Level 2 - Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The financial assets for which the Company performs recurring fair value remeasurements are cash equivalents, short-term investments and long-term investments. As of December 27, 2015 , financial assets utilizing Level 1 inputs included money market funds, and financial assets utilizing Level 2 inputs included municipal bonds, corporate bonds, certificates of deposit, and common stock of non-U.S. corporations. Level 2 assets are valued based on quoted prices in active markets for instruments that are similar or using a third-party pricing service's consensus price, which is a weighted average price based on multiple sources. These sources determine prices utilizing market income models which factor in, where applicable, transactions of similar assets in active markets, transactions of identical assets in infrequent markets, interest rates, bond or credit default swap spreads and volatility. The Company did not have any financial assets requiring the use of Level 3 inputs as of December 27, 2015 . There were no transfers between Level 1 and Level 2 during the six months ended December 27, 2015 .

Stock-Based Compensation

Stock-Based Compensation	6 Months Ended

Share-based Compensation [Abstract]
Stock-Based Compensation	Stock-Based Compensation Overview of Employee Stock-Based Compensation Plans The Company currently has one equity-based compensation plan, the 2013 Long-Term Incentive Compensation Plan (2013 LTIP), from which stock-based compensation awards can be granted to employees and directors. The 2013 LTIP provides for awards in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other awards. The Company has other equity-based compensation plans that have been terminated so that no future grants can be made under those plans, but under which stock options, restricted stock and restricted stock units are currently outstanding. The Company’s stock-based awards can be either service-based or performance-based. Performance-based conditions are generally tied to future financial and/or operating performance of the Company. The compensation expense with respect to performance-based grants is recognized if the Company believes it is probable that the performance condition will be achieved. The Company reassesses the probability of the achievement of the performance condition at each reporting period, and adjusts the compensation expense for subsequent changes in the estimate or actual outcome. As with non-performance based awards, compensation expense is recognized over the vesting period. The vesting period runs from the date of grant to the expected date that the performance objective is likely to be achieved. The Company also has an Employee Stock Purchase Plan (ESPP) that provides employees with the opportunity to purchase common stock at a discount. The ESPP limits employee contributions to 15% of each employee’s compensation (as defined in the plan) and allows employees to purchase shares at a 15% discount to the fair market value of common stock on the purchase date two times per year. The ESPP provides for a twelve-month participation period, divided into two equal six-month purchase periods, and also provides for a look-back feature. At the end of each six-month period in April and October, participants purchase the Company’s common stock through the ESPP at a 15% discount to the fair market value of the common stock on the first day of the twelve-month participation period or the purchase date, whichever is lower. The plan also provides for an automatic reset feature to start participants on a new twelve-month participation period if the fair market value of common stock declines during the first six-month purchase period. Stock Option Awards The following table summarizes stock option awards outstanding as of December 27, 2015 and changes during the six months then ended (numbers of shares in thousands): Number of Shares Weighted Average Exercise Price Outstanding at June 28, 2015 10,714 $43.10 Granted 1,863 $26.01 Exercised (129 ) $22.71 Forfeited or expired (711 ) $44.19 Outstanding at December 27, 2015 11,737 $40.55 Restricted Stock Awards and Units A summary of nonvested restricted stock awards (RSAs) and restricted stock unit awards (RSUs) outstanding as of December 27, 2015 , and changes during the six months then ended is as follows (numbers of awards and units in thousands): Number of RSAs/RSUs Weighted Average Grant-Date Fair Value Nonvested at June 28, 2015 926 $45.47 Granted 1,160 $26.05 Vested (339 ) $44.98 Forfeited (116 ) $43.60 Nonvested at December 27, 2015 1,631 $31.89 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. Total stock-based compensation expense was as follows (in thousands): Three Months Ended Six Months Ended December 27, December 28, December 27, December 28, Income Statement Classification: Cost of revenue, net $3,120 $3,448 $6,148 $6,353 Research and development 3,328 4,112 6,860 8,583 Sales, general and administrative 7,942 8,876 16,454 18,260 Total stock-based compensation expense $14,390 $16,436 $29,462 $33,196

Income Taxes

Income Taxes	6 Months Ended
	Dec. 27, 2015
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The variation between the Company's effective income tax rate and the U.S. statutory rate of 35% is due to a percentage of the Company's projected income for the full year being derived from international locations with lower tax rates than the U.S. and the impact of tax credits available in the current year. A change in the mix of pretax income in the Company's various tax jurisdictions can have a material impact on the Company's periodic effective tax rate. The research and development credit, which had previously expired on December 31, 2014, was reinstated as part of the Protecting Americans from Tax Hikes Act of 2015, enacted on December 18, 2015. This legislation retroactively reinstated and permanently extended the research and development credit. The Company recognized a $1.8 million benefit for this credit in the three months ended December 27, 2015, which was primarily a catch-up benefit for second half of fiscal 2015 and the first quarter of fiscal 2016. U.S. GAAP requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is cumulatively more than 50% likely to be realized upon ultimate settlement. As of June 28, 2015 , the Company's liability for unrecognized tax benefits was $17.8 million . During the six months ended December 27, 2015 , the Company recognized a $0.6 million increase to the liability for unrecognized tax benefits due to uncertainty regarding intercompany transactions recently challenged by the Italian tax authority. As a result, the total liability for unrecognized tax benefits as of December 27, 2015 was $18.4 million . If any portion of this $18.4 million is recognized, the Company will then include that portion in the computation of its effective tax rate. Although the ultimate timing of the resolution and/or closure of audits is highly uncertain, the Company believes it is reasonably possible that $0.2 million of gross unrecognized tax benefits will change in the next 12 months as a result of statute requirements. The Company files U.S. federal, U.S. state and foreign tax returns. For U.S. federal purposes, the Company is generally no longer subject to tax examinations for fiscal years prior to 2012. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2011. For foreign purposes, the Company is generally no longer subject to tax examinations for tax periods 2005 and prior. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture. The Company is currently under audit by the Italian Revenue Agency for the fiscal year ended June 30, 2013.

The warranty periods range from 90 days to 10 years . The Company accrues warranty liabilities at the time of sale, based on historical and projected incident rates and expected future warranty costs. The Company accrues estimated costs related to product recalls based on a formal campaign soliciting repair or return of that product when they are deemed probable and reasonably estimable. The warranty reserves, which are primarily related to Lighting Products, are evaluated quarterly based on various factors including historical warranty claims, assumptions about the frequency of warranty claims, and assumptions about the frequency of product failures derived from quality testing, field monitoring and the Company's reliability estimates. As of December 27, 2015 , $0.9 million of the Company's product warranty liabilities were classified as long-term. In June 2015, the Company issued a voluntary recall of its linear LED T8 replacement lamps due to the hazard of overheating and melting. The Company expects the majority of the costs of the recall to be recoverable from insurance proceeds resulting in an immaterial impact to the Company’s financial results. Litigation The Company is currently a party to various legal proceedings. While management presently believes that the ultimate outcome of such proceedings, individually and in the aggregate, will not materially harm the Company’s financial position, cash flows, or overall trends in results of operations, legal proceedings are subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include money damages or, in matters for which injunctive relief or other conduct remedies may be sought, an injunction prohibiting the Company from selling one or more products at all or in particular ways. Were unfavorable final outcomes to occur, there exists the possibility of a material adverse impact on the Company’s business, results of operation, financial position and overall trends. The outcomes in these matters are not reasonably estimable.

Segment Reporting [Abstract]
Reportable Segments	Reportable Segments The Company's operating and reportable segments are: • Lighting Products • LED Products • Power and RF Products Reportable Segments Description The Company's Lighting Products segment primarily consists of LED lighting systems and bulbs. The Company's LED Products segment includes LED chips, LED components and SiC materials. The Company's Power and RF Products segment includes power devices and RF devices. 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 six months ended December 27, 2015 and December 28, 2014 . 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 Income (Loss) must be included to reconcile the consolidated gross profit presented in the table below to the Company's consolidated income (loss) 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. Revenue, gross profit and gross margin for each of the Company's segments were as follows (in thousands, except percentages): Three Months Ended Six Months Ended December 27, December 28, December 27, December 28, Revenue: Lighting Products revenue $254,970 $230,168 $503,001 $453,254 LED Products revenue 153,362 151,877 301,570 325,467 Power and RF Products revenue 27,474 31,112 56,724 62,108 Total revenue $435,806 $413,157 $861,295 $840,829 Gross Profit and Gross Margin: Lighting Products gross profit $72,642 $64,701 $141,723 $120,293 Lighting Products gross margin 28.5 % 28.1 % 28.2 % 26.5 % LED Products gross profit 53,242 59,424 105,901 127,048 LED Products gross margin 34.7 % 39.1 % 35.1 % 39.0 % Power and RF Products gross profit 14,346 17,260 28,669 35,117 Power and RF Products gross margin 52.2 % 55.5 % 50.5 % 56.5 % Total segment gross profit 140,230 141,385 276,293 282,458 Unallocated costs (5,079 ) (4,606 ) (9,394 ) (9,859 ) Consolidated gross profit $135,151 $136,779 $266,899 $272,599 Consolidated gross margin 31.0 % 33.1 % 31.0 % 32.4 % Assets by Reportable Segment Inventories are the only assets reviewed by the Company's CODM when evaluating segment performance and allocating resources to the segments. The CODM reviews all of the Company's assets other than inventories on a consolidated basis. Unallocated inventories in the table below were not allocated to the reportable segments because the Company’s CODM does not review them when evaluating performance and allocating resources to each segment. Unallocated inventories consisted primarily of manufacturing employees’ stock-based compensation, profit sharing and quarterly or annual incentive compensation and matching contributions under the Company’s 401(k) plan . Inventories for each of the Company's segments were as follows (in thousands): December 27, June 28, Lighting Products $148,872 $150,755 LED Products 110,349 114,203 Power and RF Products 16,601 11,536 Total segment inventories 275,822 276,494 Unallocated inventories 4,988 4,082 Consolidated inventories $280,810 $280,576

Basis of Presentation	Basis of Presentation The consolidated balance sheet at December 27, 2015 , the consolidated statements of income (loss) for the three and six months ended December 27, 2015 and December 28, 2014 , the consolidated statements of comprehensive income (loss) for the three and six months ended December 27, 2015 and December 28, 2014 , and the consolidated statements of cash flows for the six months ended December 27, 2015 and December 28, 2014 (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 and cash flows at December 27, 2015 , and for all periods presented, have been made. All intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 28, 2015 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 28, 2015 (fiscal 2015 ). The results of operations for the three and six months ended December 27, 2015 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 26, 2016 (fiscal 2016 ). 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 2015 amounts in the accompanying consolidated financial statements have been reclassified to conform to the fiscal 2016 presentation. These reclassifications had no effect on previously reported consolidated net income or shareholders’ equity.
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 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 accounting guidance. Income Taxes In November 2015, the FASB issued ASU No. 2015-17: Income Taxes (Topic 740). The ASU requires entities to present deferred tax assets and deferred tax liabilities as noncurrent in a classified balance sheet. The ASU simplifies the current guidance, which requires entities to separately present deferred tax assets and deferred tax liabilities as current or noncurrent in a classified balance sheet. The ASU is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early application of the ASU is permitted as of the beginning of an interim or annual reporting period and may be applied either prospectively or retrospectively to all periods presented. The Company has adopted the provisions of this ASU prospectively for the interim period ended December 27, 2015 and therefore, prior periods were not retrospectively adjusted. The Company’s adoption of the new accounting guidance did not 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 six months ended December 27, 2015 and December 28, 2014 . 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 Income (Loss) must be included to reconcile the consolidated gross profit presented in the table below to the Company's consolidated income (loss) 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.
