Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations [Text Block]	Business 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 lamps. 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 chips and LED components. The Company's LED products enable its customers to develop and market LED-based products for lighting, video screens, automotive and other industrial applications. The Company’s Wolfspeed business consists of silicon carbide (SiC) materials, power devices and RF devices based on wide bandgap semiconductor materials such as SiC and gallium nitride (GaN). The Company’s materials products and power devices are used in solar, electric vehicles, motor drives, power supplies and transportation applications. The Company’s RF devices are used in military communications, radar, satellite and telecommunication applications. 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, Arkansas, California, Wisconsin, India, Italy 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 • Wolfspeed For financial results by reportable segment, please refer to Note 14 , “Reportable Segments.”
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Termination of Wolfspeed Sale Transaction On July 13, 2016, the Company executed an Asset Purchase Agreement (the APA) with Infineon, which was approved by both the Company’s Board of Directors and Infineon’s Supervisory Board. Pursuant to the APA, the Company agreed to sell to Infineon, and Infineon agreed to (i) purchase from the Company (a) the assets comprising the Company’s power and RF product lines (formerly the Company's Power and RF Products segment), including manufacturing facilities and equipment, inventory, intellectual property rights, contracts, real estate, and the outstanding equity interests of Cree Fayetteville, Inc, one of the Company’s wholly-owned subsidiaries, and (b) certain related portions of the Company’s SiC materials and gemstones business previously included within the LED Products segment and (ii) assume certain liabilities related to the Wolfspeed business. Beginning in July 2016, the Company classified the results of the Wolfspeed business as discontinued operations in the Company’s consolidated statements of loss for all periods presented. The Company also ceased recording depreciation and amortization of long-lived assets of the Wolfspeed business upon classification as discontinued operations in July 2016. Additionally, the related assets and liabilities associated with the discontinued operations were classified as held for sale in the consolidated balance sheets. On February 16, 2017, the Company announced that the APA would be terminated as the Company and Infineon were unable to identify alternatives to modify the transaction to address the national security concerns of, and obtain approval from, the Committee on Foreign Investment in the United States, one of the closing conditions under the APA. On March 6, 2017, the Company and Infineon entered into a Termination Agreement pursuant to which the APA was terminated. Pursuant to the APA and the Termination Agreement, Infineon paid the Company a termination fee of $12.5 million in cash on March 10, 2017, which is included in Wolfspeed transaction termination fee in the Company’s consolidated statements of loss and in net cash provided by operating activities in the Company’s consolidated statements of cash flows. As a result of the announcement of the termination of the APA and the Company’s decision to continue operating the Wolfspeed business, as of February 16, 2017, the Company reclassified the results of the Wolfspeed business as continuing operations in the Company’s consolidated statements of loss, and presented it as a separate reportable segment for all periods presented. Additionally, the related assets and liabilities of the Wolfspeed business were reclassified as held and used in the consolidated balance sheets for all periods presented. The long-lived assets were measured at the lower of their carrying amount before being classified as held for sale, adjusted for any depreciation and amortization expense that would have been recognized had the assets been continuously classified as held and used, or their fair value at the date of the subsequent decision not to sell.

Basis of Presentation and Changes in Significant Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Company, and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. Fiscal Year The Company’s fiscal year is a 52 or 53 -week period ending on the last Sunday in the month of June. The Company’s 2017 , 2016 and 2015 fiscal years were 52 -week fiscal years. The Company’s 2018 fiscal year will be a 52 -week fiscal year. Reclassifications Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net loss or shareholders’ equity. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (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. The Company evaluates its estimates on an ongoing basis, including those related to revenue recognition, product warranty obligations, valuation of inventories, tax related contingencies, valuation of stock-based compensation, valuation of long-lived and intangible assets, other contingencies and litigation, among others. The Company generally bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates. Segment Information U.S. GAAP requires segmentation based on an entity’s internal organization and reporting of revenue and operating income based upon internal accounting methods commonly referred to as the “management approach.” Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (CODM), or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it currently has three operating and reportable segments. Cash and Cash Equivalents Cash and cash equivalents consist of unrestricted cash accounts and highly liquid investments with an original maturity of three months or less when purchased. Cash and cash equivalents are stated at cost, which approximates fair value. The Company holds cash and cash equivalents at several major financial institutions, which often exceed insurance limits set by the Federal Deposit Insurance Corporation (FDIC). The Company has not historically experienced any losses due to such concentration of credit risk. Investments Investments in certain securities may be classified into three categories: • Held-to-Maturity – Debt securities that the entity has the positive intent and ability to hold to maturity, which are reported at amortized cost. • Trading – Debt and equity securities that are bought and held principally for the purpose of selling in the near term, which are reported at fair value, with unrealized gains and losses included in earnings. • Available-for-Sale – Debt and equity securities not classified as either held-to-maturity or trading securities, which are reported at fair value with unrealized gains or losses excluded from earnings and reported as a separate component of shareholders’ equity. The Company reassesses the appropriateness of the classification (i.e. held-to-maturity, trading or available-for-sale) of its investments at the end of each reporting period. When the fair value of an investment declines below its original cost, the Company considers all available evidence to evaluate whether the decline is other-than-temporary. Among other things, the Company considers the duration and extent of the decline and economic factors influencing the capital markets. For the fiscal years ended June 25, 2017 , June 26, 2016 , and June 28, 2015 , the Company had no other-than-temporary declines below the cost basis of its investments. The Company utilizes specific identification in computing realized gains and losses on the sale of investments. Realized gains and losses on the sale of investments are reported in other income and expense. Investments in marketable securities with maturities beyond one year may be classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. Other long-term investments consist of the Company's approximately 15% common stock ownership interest in Lextar Electronics Corporation (Lextar), which the Company acquired in December 2014. This investment was accounted for under the equity method from the date of investment until June 2016 when the Company chose for its representative not to stand for re-election as a member of the Lextar board of directors. The Company utilizes the fair value option in accounting for its investment in Lextar. The Company has determined that for its fiscal years ended June 26, 2016 and June 28, 2015, Lextar has met the conditions of a significant subsidiary under Rule 1-02(w) of Regulation S-X for which the Company is required, pursuant to Rule 3-09 of Regulation S-X, to file separate financial statements as an exhibit to its Annual Report on Form 10-K. As such, separate financial statements for Lextar , prepared by Lextar and audited by its independent public accounting firm, are filed as Exhibit 99.1 to the Company's Annual Report. Inventories Inventories are stated at lower of cost or market, with cost determined on a first-in, first-out (FIFO) method or an average cost method; and with market not to exceed net realizable value. The Company writes down its inventory balances for estimates of excess and obsolete amounts. These write-downs are recognized as a component of cost of revenue. At the point of the write-down, a new lower-cost basis for that inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase in that newly established lower-cost basis. The Company recognized charges for write-downs in inventories of $7.3 million , $3.6 million and $15.2 million , for fiscal 2017 , 2016 and 2015 , respectively. Property and Equipment Property and equipment are stated at cost and depreciated on a straight-line basis over the assets’ estimated useful lives. Leasehold improvements are amortized over the lesser of the asset life or the life of the related lease. In general, the Company’s policy for useful lives is as follows: Machinery and equipment 3 to 15 years Buildings and building improvements 5 to 40 years Furniture and fixtures 3 to 5 years Aircraft and vehicles 5 to 20 years Leasehold improvements Shorter of estimated useful life or lease term Expenditures for repairs and maintenance are charged to expense as incurred. The costs for major renewals and improvements are capitalized and depreciated over their estimated useful lives. The cost and related accumulated depreciation of the assets are removed from the accounts upon disposition and any resulting gain or loss is reflected in operating income. Shipping and Handling Costs Shipping and handling costs are included in Cost of revenue, net in the Consolidated Statements of Loss and are recognized as a period expense during the period in which they are incurred. Goodwill and Intangible Assets The Company recognizes the assets acquired and liabilities assumed in business combinations at their respective fair values at the date of acquisition, with any excess purchase price recognized as goodwill. Valuation of intangible assets entails significant estimates and assumptions including, but not limited to, estimating future cash flows from product revenue, developing appropriate discount rates, continuation of customer relationships and renewal of customer contracts, and approximating the useful lives of the intangible assets acquired. Goodwill The Company recognizes goodwill as an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The Company tests goodwill for impairment at least annually as of the first day of the fiscal fourth quarter, or when indications of potential impairment exist. The Company monitors for the existence of potential impairment indicators throughout the fiscal year. The Company conducts impairment testing for goodwill at the reporting unit level. Reporting units may be operating segments as a whole or an operation one level below an operating segment, referred to as a component. The Company has determined that its reporting units are its three operating and reportable segments. The Company may initiate goodwill impairment testing by considering qualitative factors to determine whether it is more likely than not that a reporting unit’s carrying value is greater than its fair value. Such factors may include the following, among others: a significant decline in the reporting unit ’ s expected future cash flows; a sustained, significant decline in the Company ’ s stock price and market capitalization; a significant adverse change in legal factors or in the business climate; unanticipated competition; and slower growth rates; as well as changes in management, key personnel, strategy and customers . If the Company’s qualitative assessment indicates that goodwill impairment is more likely than not, the Company performs the two-step goodwill impairment test. Alternatively, the Company may bypass the qualitative test and initiate goodwill impairment testing with the first step of the two-step goodwill impairment test. During the first step of the goodwill impairment test, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company derives a reporting unit ’ s fair value through a combination of the market approach (a guideline transaction method) and the income approach (a discounted cash flow analysis). The income approach utilizes a discount rate from the capital asset pricing model. If all reporting units are analyzed during the first step of the goodwill impairment test, their respective fair values are reconciled back to the Company ’ s consolidated market capitalization. If the fair value of a reporting unit exceeds its carrying value, then the Company concludes that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company performs the second step of the goodwill impairment test to measure possible goodwill impairment loss. During the second step, the Company hypothetically values the reporting unit ’ s tangible and intangible assets and liabilities as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit ’ s goodwill is compared to the carrying value of its goodwill. If the carrying value of the reporting unit ’ s goodwill exceeds the implied fair value of the goodwill, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying value of the reporting unit ’ s goodwill. Once an impairment loss is recognized, the adjusted carrying value of the goodwill becomes the new accounting basis of the goodwill for the reporting unit. Indefinite-Lived Intangible Assets The Company ’ s indefinite-lived intangible assets are tested for impairment at least annually in the fiscal fourth quarter or when indications of potential impairment exist. The Company monitors for the existence of potential impairment indicators throughout the fiscal year. The Company ’ s impairment test may begin with a qualitative test to determine whether it is more likely than not that an indefinite-lived intangible asset ’ s carrying value is greater than its fair value. In performing this test, the Company may consider the following qualitative factors, among others: a significant decline in expected future cash flows; changes in industry and market conditions such as the deterioration in the environment in which the Company operates or an increased competitive environment; changes in management, key personnel, strategy, or customers; as well as other economic factors. If the Company’s qualitative assessment indicates that asset impairment is more likely than not, the Company performs a quantitative impairment test by comparing the fair value of the indefinite-lived intangible asset to its carrying value. Alternatively, the Company may bypass the qualitative test and initiate impairment testing with the quantitative impairment test. Determining the fair value of indefinite-lived intangible assets entails significant estimates and assumptions including, but not limited to, determining the timing and expected costs to complete development projects, estimating future cash flows from product revenue, developing appropriate discount rates, estimating probability rates for the successful completion of development projects, continuation of customer relationships and renewal of customer contracts, and approximating the useful lives of the intangible assets acquired. If the fair value of the indefinite-lived intangible asset exceeds its carrying value, then the Company concludes that no impairment has occurred. If the carrying value of the indefinite-lived intangible asset exceeds its fair value, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying value. Once an impairment loss is recognized, the adjusted carrying value becomes the new accounting basis of the indefinite-lived intangible asset. Finite-Lived Intangible Assets U.S. GAAP requires that intangible assets, other than goodwill and indefinite-lived intangibles, must be amortized over their useful lives. The Company is currently amortizing its acquired intangible assets with finite lives over periods ranging from one to 20 years . Patent rights reflect costs incurred by the Company in applying for and maintaining patents owned by the Company and costs incurred in purchasing patents and related rights from third parties. Licensing rights reflect costs incurred by the Company in acquiring licenses under patents owned by others. The Company amortizes both on a straight-line basis over the expected useful life of the associated patent rights, which is generally the lesser of 20 years from the date of the patent application or the license period. Royalties payable under licenses for patents owned by others are generally expensed as incurred. The Company reviews its capitalized patent portfolio and recognizes impairment charges when circumstances warrant, such as when patents have been abandoned or are no longer being pursued. Long-Lived Assets The Company reviews long-lived assets such as property and equipment for impairment based on changes in circumstances that indicate their carrying amounts may not be recoverable. In making these determinations, the Company uses certain assumptions, including but not limited to: (1) estimations of the fair market value of the assets and (2) estimations of future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company’s operations and estimated salvage values. Contingent Liabilities The Company recognizes contingent liabilities when it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Disclosure in the notes to the financial statements is required for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred. See Note 13 , “Commitments and Contingencies,” for a discussion of loss contingencies in connection with pending and threatened litigation. The Company expenses as incurred the costs of defending legal claims against the Company. Revenue Recognition The Company recognizes product revenue when the earnings process is complete, as evidenced by persuasive evidence of an arrangement (typically in the form of a purchase order), when the sales price is fixed or determinable, collection of revenue is reasonably assured, and title and risk of loss have passed to the customer. The Company provides its customers with limited rights of return for non-conforming shipments and product warranty claims. The Company estimates an allowance for anticipated sales returns based upon an analysis of historical sales returns and other relevant data. The Company recognizes an allowance for non-conforming returns at the time of sale as a reduction of product revenue and as a reduction to the related accounts receivable balance. The Company recognizes a liability for product warranty claims at the time of sale as an increase to cost of revenue. A substantial portion of the Company’s products are sold through distributors. Distributors stock inventory and sell the Company’s products to their own customer base, which may include: value added resellers; manufacturers who incorporate the Company’s products into their own manufactured goods; or ultimate end users of the Company’s products. The Company recognizes revenue upon shipment of its products to its distributors. This arrangement is often referred to as a “sell-in” or “point-of-purchase” model as opposed to a “sell-through” or “point-of-sale” model, where revenue is deferred and not recognized until the distributor sells the product through to their customer. Certain of the Company’s distributors are provided limited rights that allow them to return a portion of inventory (product exchange rights or stock rotation rights) and receive credits for changes in selling prices (price protection rights) or customer pricing arrangements under the Company’s “ship and debit” program or other targeted sales incentives. These estimates are calculated based upon historical experience, product shipment analysis, current economic conditions, on-hand inventory at the distributor, and customer contractual arrangements. The Company believes that it can reasonably and reliably estimate the allowance for distributor credits at the time of sale. Accordingly, estimates for these rights are recognized at the time of sale as a reduction of product revenue and as a reduction to the related accounts receivable balance. From time to time, the Company will issue a new price book for its products, and provide a credit to certain distributors for inventory quantities on hand if required by the Company’s agreement with the distributor. This practice is known as price protection. These credits are applied against the reserve that the Company establishes upon initial shipment of product to the distributor. Under the ship and debit program, products are sold to distributors at negotiated prices and the distributors are required to pay for the products purchased within the Company’s standard commercial terms. Subsequent to the initial product purchase, a distributor may request a price allowance for a particular part number(s) for certain target customers, prior to the distributor reselling the particular part to that customer. If the Company approves an allowance and the distributor resells the product to the target customer, the Company credits the distributor according to the allowance the Company approved. These credits are applied against the reserve that the Company establishes upon initial shipment of product to the distributor. In addition, the Company runs sales incentive programs with certain distributors and retailers, such as product rebates and cooperative advertising campaigns. The Company recognizes these incentives at the time they are offered to customers and records a credit to their account with an offsetting expense as either a reduction to revenue, increase to cost of revenue, or marketing expense depending on the type of sales incentive. From time to time, the Company may enter into licensing arrangements related to its intellectual property. Revenue from licensing arrangements is recognized when earned and estimable. The timing of revenue recognition is dependent on the terms of each license agreement. Generally, the Company will recognize non-refundable upfront licensing fees related to patent licenses immediately upon receipt of the funds if the Company has no significant future obligations to perform under the arrangement. However, the Company will defer recognition for licensing fees where the Company has significant future performance requirements, the fee is not fixed (such as royalties earned as a percentage of future revenue), or the fees are otherwise contingent. Accounts Receivable For product revenue, the Company typically invoices its customers at the time of shipment for the sales order value of products shipped. Accounts receivable are recognized at the invoiced amount and are not subject to any interest or finance charges. The Company does not have any off-balance sheet credit exposure related to any of its customers. Allowance for Doubtful Accounts The Company evaluates the collectability of accounts receivable based on a combination of factors. In cases where the Company becomes aware of circumstances that may impair a specific customer’s ability to meet its financial obligations subsequent to the original sale, the Company will recognize an allowance against amounts due, and thereby reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers, the Company recognizes an allowance for doubtful accounts based on the length of time the receivables are past due and consideration of other factors such as industry conditions, the current business environment and the Company’s historical experience. Advertising The Company expenses the costs of producing advertisements at the time production occurs and expenses the cost of communicating the advertising in the period in which the advertising is used. Advertising costs are included in Sales, general and administrative expenses in the Consolidated Statements of Loss and amounted to approximately $13.0 million , $12.6 million , and $25.6 million for the years ended June 25, 2017 , June 26, 2016 and June 28, 2015 , respectively. Research and Development Research and development activities are expensed when incurred. Loss Per Share Basic loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding for the applicable period. Diluted loss per share is determined in the same manner as basic loss per share except that the number of shares is increased to assume exercise of potentially dilutive stock options, nonvested restricted stock and contingently issuable shares using the treasury stock method, unless the effect of such increases would be anti-dilutive. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recognized in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares. Stock-Based Compensation The Company recognizes compensation expense for all share-based payments granted based on the fair value of the shares on the date of grant. Compensation expense is then recognized over the award’s vesting period. Fair Value of Financial Instruments Cash and cash equivalents, short-term investments, accounts and interest receivable, accounts payable and other liabilities approximate their fair values at June 25, 2017 and June 26, 2016 due to the short-term nature of these instruments. Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets are recognized for deductible temporary differences, along with net operating loss carryforwards and credit carryforwards, if it is more likely than not that the tax benefits will be realized. To the extent a deferred tax asset cannot be recognized under the preceding criteria, allowances are established. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Taxes payable which are not based on income are accrued ratably over the period to which they apply. For example, payroll taxes are accrued each period end based upon the amount of payroll taxes that are owed as of that date; whereas taxes such as property taxes and franchise taxes are accrued over the fiscal year to which they apply if paid at the end of a period, or they are amortized ratably over the fiscal year if they are paid in advance. Sales Taxes The Company presents sales taxes collected from customers and remitted to governmental authorities on a net basis (i.e. excluded from revenue and expenses). Foreign Currency Translation Foreign currency translation adjustments are recognized in Other comprehensive (loss) income in the Consolidated Statements of Comprehensive Loss for changes between the foreign subsidiaries’ functional currency and the United States (U.S.) dollar. Foreign currency translation gains and losses are included in the Company’s equity account balance of Accumulated other comprehensive income, net of taxes in the Consolidated Balance Sheets until such time that the subsidiaries are either sold or substantially liquidated. Because the Company and its subsidiaries transact business in currencies other than the U.S. Dollar, the Company will continue to experience varying amounts of foreign currency exchange gains and losses for subsidiaries with U.S. dollar functional currency. 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 Company’s evaluation of ASU 2014-09 is ongoing and not complete; however, the Company anticipates the primary changes to revenue recognition to be related to certain patent license arrangements. The FASB has issued and may issue in the future, interpretive guidance, which may cause our evaluation to change. The effective date will be the first quarter of the Company's fiscal year ending June 30, 2019 and the Company currently expects to use the modified retrospective method. 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 24, 2018. The Company's adoption of this ASU is not expected to impact its consolidated financial statements. 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.

Business Combinations [Abstract]
Business Combination Disclosure	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 subsequent two years, additional cash payments totaling up to $4.6 million may be made to the former APEI shareholders. Payments totaling $2.8 million were made to the former APEI shareholders in July 2016 based on achievement of the first year goals. Payments totaling $1.8 million were made to the former APEI shareholders in July 2017 based on achievement of the second year goals. In connection with this acquisition, APEI became a wholly owned subsidiary of the Company, renamed Cree Fayetteville, Inc. (Cree Fayetteville). Cree Fayetteville is not considered a significant subsidiary of the Company and its results from operations are reported as part of the Company's Wolfspeed segment. The total purchase price for this acquisition was 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 & 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 7 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. The IPR&D was completed in January 2016. 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 on the sale of investments for the fiscal year ended June 25, 2017 of $93 thousand were included in Non-operating income (expense), net in the Consolidated Statements of 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 investments to be impaired as of June 25, 2017 and June 26, 2016 . The contractual maturities of short-term investments at June 25, 2017 were as follows (in thousands): Within One Year After One, Within Five Years After Five, Within Ten Years After Ten Years Total Municipal bonds $45,519 $107,947 $26,575 $— $180,041 Corporate bonds 48,515 94,637 34,569 — 177,721 Non-U.S. certificates of deposit 5,755 114,624 — — 120,379 U.S. certificates of deposit — — — — — Commercial paper 200 — — — 200 Total short-term investments $99,989 $317,208 $61,144 $— $478,341

Fair Value of Financial Instrum

Fair Value of Financial Instruments	12 Months Ended

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 and short-term investments and long-term investments. As of June 25, 2017 , financial assets utilizing Level 1 inputs included money market funds, and financial assets utilizing Level 2 inputs included municipal bonds, corporate bonds, non-U.S. certificates of deposit, commercial paper, 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 June 25, 2017 . There were no transfers between Level 1 and Level 2 during the year ended June 25, 2017 .

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill The Company’s reporting units for goodwill impairment testing are: • Lighting Products • LED Products • Wolfspeed As of the first day of the fourth quarter of fiscal 2017 , the Company performed a step one quantitative goodwill impairment assessment on each reporting unit. For the step one impairment test, the Company derived each reporting unit's fair value through a combination of the market approach (a guideline transaction method) and the income approach (a discounted cash flow analysis). The Company utilized a discount rate from the capital asset pricing model for the discounted cash flow analysis. Once the reporting unit fair values were calculated, the Company reconciled the reporting units' relative fair values to the Company's market capitalization as of the testing date. The Company then compared the carrying value of each reporting unit, inclusive of its assigned goodwill, to its fair value. The Company determined that the fair value of each reporting unit exceeded its carrying value, and as a result, step two of the goodwill impairment test was not necessary. Goodwill by reporting unit as of June 25, 2017 was as follows (in thousands): LED Products Lighting Products Wolfspeed Consolidated Total $180,278 $337,781 $100,769 $618,828 Goodwill by reporting unit as of June 26, 2016 was as follows (in thousands): LED Products Lighting Products Wolfspeed Consolidated Total $180,278 $337,781 $100,769 $618,828 Intangible Assets The following table presents the components of intangible assets, net (in thousands): June 25, 2017 June 26, 2016 Gross Accumulated Amortization Net Gross Accumulated Amortization Net Intangible assets with finite lives: Customer relationships $141,420 ($84,673 ) $56,747 $141,420 ($78,438 ) $62,982 Developed technology 181,728 (132,747 ) 48,981 181,728 (111,884 ) 69,844 Non-compete agreements 10,475 (10,398 ) 77 10,475 (9,994 ) 481 Trade names, finite-lived 520 (520 ) — 520 (520 ) — Patent and licensing rights 151,985 (63,155 ) 88,830 145,780 (55,957 ) 89,823 Total intangible assets with finite lives 486,128 (291,493 ) 194,635 479,923 (256,793 ) 223,130 Trade names, indefinite-lived 79,680 79,680 79,680 79,680 Total intangible assets $565,808 ($291,493 ) $274,315 $559,603 ($256,793 ) $302,810 Total amortization of finite-lived intangible assets was $39.8 million , $40.4 million and $37.1 million for the years ended June 25, 2017 , June 26, 2016 and June 28, 2015 , respectively. Beginning in the third quarter of fiscal 2016, the Company started amortizing IPR&D assets acquired in the APEI acquisition that were completed during the respective period. As of the first day of the fourth quarter of fiscal 2017 , the Company performed a step one quantitative impairment assessment on each of the Company’s indefinite-lived trade names. The Company determined that the fair value of each indefinite-lived trade name was greater than its carrying value and therefore a step two quantitative impairment assessment was not required. The Company invested $12.4 million , $14.4 million and $19.5 million for the years ended June 25, 2017 , June 26, 2016 and June 28, 2015 , respectively, for patent and licensing rights. For the fiscal years ended June 25, 2017 , June 26, 2016 and June 28, 2015 , the Company recognized $1.2 million , $6.7 million and $3.4 million , respectively, in impairment charges related to its patent portfolio. Total future amortization expense of finite-lived intangible assets is estimated to be as follows (in thousands): Fiscal Year Ending June 24, 2018 $38,858 June 30, 2019 37,320 June 28, 2020 24,463 June 27, 2021 19,192 June 26, 2022 17,816 Thereafter 56,986 Total future amortization expense $194,635

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders’ Equity On August 24, 2016, the Board of Directors approved the Company's fiscal 2017 stock repurchase program, authorizing the Company to repurchase shares of its common stock having an aggregate purchase price not exceeding $300 million for all purchases from August 24, 2016 through the expiration of the program on June 25, 2017. During fiscal 2017 , the Company repurchased 4.4 million shares of its common stock under the program at an average price of $23.55 per share with an aggregate value of $104.0 million . The repurchase program could be implemented through open market or privately negotiated transactions at the discretion of the Company’s management. From the inception of the predecessor stock repurchase program in January 2001 through June 25, 2017 , the Company has repurchased 38.7 million shares of its common stock at an average price of $28.66 per share with an aggregate value of $1.1 billion . On June 14, 2017, the Board of Directors approved the Company's fiscal 2018 stock repurchase program, authorizing the Company to repurchase shares of its common stock having an aggregate purchase price not exceeding $200 million for all purchases from June 26, 2017 through the expiration of the program on June 24, 2018 . The repurchase program may be implemented through open market or privately negotiated transactions at the discretion of the Company's management. The Company will continue to determine the time and extent of any repurchases based on its evaluation of market conditions and other factors. On May 29, 2002, the Board adopted a shareholder rights plan, pursuant to which stock purchase rights were distributed to shareholders at a rate of one right with respect to each share of common stock held of record as of June 10, 2002. Subsequently issued shares of common stock also carried stock purchase rights under the plan. The rights plan was designed to enhance the Board’s ability to prevent an acquirer from depriving shareholders of the long-term value of their investment and to protect shareholders against attempts to acquire the Company by means of unfair or abusive takeover tactics. On January 29, 2013, the shareholder rights plan was amended solely to change the expiration date from September 30, 2018 to April 24, 2017. On April 24, 2017, the shareholder rights plan expired pursuant to its terms and is no longer in effect. At June 25, 2017 , the Company had reserved a total of approximately 19.3 million shares of its common stock for future issuance as follows (in thousands): Number of Shares For exercise of outstanding common stock options 10,604 For vesting of outstanding stock units 2,347 For future equity awards under 2013 Long-Term Incentive Compensation Plan 6,214 For future issuance under the Non-Employee Director Stock Compensation and Deferral Program 65 For future issuance to employees under the 2005 Employee Stock Purchase Plan 102 Total common shares reserved 19,332

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. At June 25, 2017 , there were 10.6 million shares authorized for issuance under the plan and 6.2 million shares remaining for future grants. 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. At June 25, 2017 , there were 4.5 million shares authorized for issuance under the ESPP, as amended, with 0.1 million shares remaining for future issuance. 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 option activity as of June 25, 2017 and changes during the fiscal year then ended (numbers of shares in thousands): Number of Shares Weighted Average Exercise price Weighted Average Remaining Contractual Term Total Intrinsic Value Outstanding at June 26, 2016 11,247 $40.42 Granted 1,795 24.50 Exercised (119 ) 26.06 Forfeited or expired (2,319 ) 38.67 Outstanding at June 25, 2017 10,604 $38.27 3.49 $1,745 Vested and expected to vest at June 25, 2017 10,377 $38.54 3.44 $1,593 Exercisable at June 25, 2017 7,297 $42.22 2.62 $233 The total intrinsic value in the table above represents the total pretax intrinsic value, which is the total difference between the closing price of the Company’s common stock on June 23, 2017 (the last trading day of fiscal 2017 ) of $25.35 and the exercise price for in-the-money options that would have been received by the holders if all instruments had been exercised on June 25, 2017 . As of June 25, 2017 , there was $15.9 million of unrecognized compensation cost related to nonvested stock options, which is expected to be recognized over a weighted average period of 1.46 years.

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): Fiscal Years Ended Income Statement Classification: June 25, June 26, June 28, Cost of revenue, net $10,427 $12,394 $12,836 Research and development 10,619 13,842 16,524 Sales, general and administrative 26,679 32,492 34,939 Total stock-based compensation expense $47,725 $58,728 $64,299 The weighted average assumptions used to value stock option grants were as follows: Fiscal Years Ended Stock Option Grants: June 25, June 26, June 28, Risk-free interest rate 1.06 % 1.18 % 1.17 % Expected life, in years 3.80 3.66 3.54 Expected volatility 42.4 % 43.3 % 45.2 % Dividend yield — — — The following describes each of these assumptions and the Company’s methodology for determining each assumption: Risk-Free Interest Rate The Company estimates the risk-free interest rate using the U.S. Treasury bill rate with a remaining term equal to the expected life of the award. Expected Life The expected life represents the period that the stock option awards are expected to be outstanding. In determining the appropriate expected life of its stock options, the Company segregates its grantees into categories based upon employee levels that are expected to be indicative of similar option-related behavior. The expected useful lives for each of these categories are then estimated giving consideration to (1) the weighted average vesting periods, (2) the contractual lives of the stock options, (3) the relationship between the exercise price and the fair market value of the Company’s common stock, (4) expected employee turnover, (5) the expected future volatility of the Company’s common stock, and (6) past and expected exercise behavior, among other factors. Expected Volatility The Company estimates expected volatility giving consideration to the expected life of the respective award, the Company’s current expected growth rate, implied volatility in traded options for its common stock, and the historical volatility of its common stock. Expected Dividend Yield The Company estimates the expected dividend yield by giving consideration to its current dividend policies as well as those anticipated in the future considering the Company’s current plans and projections.

Based on this evaluation, during the fiscal year ended June 25, 2017 , the Company recorded a valuation allowance of $101.8 million against its U.S. deferred tax assets. In addition, the company recognized a related deferred tax charge of $17.9 million . During the fourth quarter of fiscal 2016, the Company concluded it is likely that sufficient future taxable income needed to fully utilize net operating loss carryovers in Luxembourg will not be generated due to additional losses on the Company’s equity method investment held there. The Company recorded a $9.5 million valuation allowance against the related deferred tax asset, representing the $32.4 million net operating loss carryover net of tax. During the fiscal year ended June 25, 2017 , the Company reduced the valuation allowance against the loss carryover deferred tax assets by $1.0 million as a result of a decrease in the effective tax rate. As of June 25, 2017 , the Company had approximately $36.2 million of foreign net operating loss carryovers, of which $32.4 million are offset by a valuation allowance. The foreign net operating loss carryovers have no carry forward limitation. As of June 25, 2017 , the Company had approximately $39.3 million of state net operating loss carryovers which are fully offset by a valuation allowance. Additionally, the Company had $45.7 million of federal and $6.3 million of state income tax credit carryforwards which are fully offset by a valuation allowance. The state net operating loss carryovers will begin to expire in fiscal 2018 . The federal and state income tax credit carryforwards will begin to expire in fiscal 2032 and fiscal 2018 , respectively. 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 26, 2016 the Company’s liability for unrecognized tax benefits was $17.7 million . During the fiscal year ended June 25, 2017, the Company recognized a $4.4 million decrease to the liability for unrecognized tax benefits; $3.7 million following statute expirations, $0.6 million related to settlement of the audit by the Italian Revenue Agency and $0.1 million related to a decrease in the effective tax rate. As a result, the total liability for unrecognized tax benefits as of June 25, 2017 was $13.3 million . If any portion of this $13.3 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 approximately $0.2 million of gross unrecognized tax benefits will change in the next 12 months as a result of statute requirements. The following is a tabular reconciliation of the Company’s change in uncertain tax positions (in thousands): Fiscal Years Ended June 25, June 26, June 28, Balance at beginning of period $17,727 $17,795 $18,389 Increases related to prior year tax positions — 617 — Decreases related to prior year tax positions (100 ) (530 ) (407 ) Settlements with tax authorities (608 ) — — Expiration of statute of limitations for assessment of taxes (3,681 ) (155 ) (187 ) Balance at end of period $13,338 $17,727 $17,795 The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the Income tax (benefit) expense line item in the Consolidated Statements of Loss. Total interest and penalties accrued were as follows (in thousands): June 25, June 26, Accrued interest and penalties $2 ($5 ) Total interest and penalties recognized were as follows (in thousands): Fiscal Years Ended June 25, June 26, June 28, Recognized interest and penalties (benefit) $7 ($15 ) ($94 ) 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 2014 . For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2013 . For foreign purposes, the Company is generally no longer subject to examination for tax periods 2007 and prior. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture. On January 20, 2017, the Company settled an ongoing audit by the Italian Revenue Agency for the fiscal year ended June 30, 2013, resulting in immaterial impact on tax expense. The Company provides for U.S. income taxes on the earnings of foreign subsidiaries unless the subsidiaries’ earnings are considered indefinitely reinvested outside the United States. As of June 25, 2017 , U.S. income taxes were not provided for on a cumulative total of approximately $262.0 million of undistributed earnings for certain non-U.S. subsidiaries, as the Company currently intends to reinvest these earnings in these foreign operations indefinitely. If, at a later date, these earnings were repatriated to the U.S., the Company would be required to pay taxes on these amounts. Determination of the amount of any deferred tax liability on these undistributed earnings is not practicable. During the fiscal year ended June 26, 2011, the Company was awarded a tax holiday in Malaysia with respect to its manufacturing and distribution operations. This arrangement allows for 0% tax for 10 years starting in the fiscal year ended June 26, 2011. For the fiscal years 2015, 2016 and 2017, the Company did not meet the requirements for the tax holiday, and as such, no benefit has been recognized.

Commitments and Contingencies	Commitments and Contingencies Warranties The following table summarizes the changes in the Company’s product warranty liabilities (in thousands): Fiscal Years Ended June 25, June 26, June 28, Balance at beginning of period $21,531 $13,968 $6,822 Warranties accrued in current period 32,024 19,866 9,242 Recall costs accrued in current period — 5,756 5,418 Expenditures (25,636 ) (18,059 ) (7,514 ) Balance at end of period $27,919 $21,531 $13,968 Product warranties are estimated and recognized at the time the Company recognizes revenue. 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 June 25, 2017 , $14.3 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. Lease Commitments The Company primarily leases manufacturing, office, housing and warehousing space under the terms of non-cancelable operating leases. These leases expire at various times through April 2024 . The Company recognizes net rent expense on a straight-line basis over the life of the lease. Rent expense associated with these operating leases totaled approximately $7.0 million , $6.6 million and $8.2 million for each of the fiscal years ended June 25, 2017 , June 26, 2016 and June 28, 2015 , respectively. Certain agreements require that the Company pay property taxes and general property maintenance in addition to the minimum rental payments. Future minimum rental payments as of June 25, 2017 (under leases currently in effect) are as follows (in thousands): Fiscal Years Ending Minimum Rental Amount June 24, 2018 $4,905 June 30, 2019 3,364 June 28, 2020 2,892 June 27, 2021 1,350 June 26, 2022 692 Thereafter 1,259 Total future minimum rental payments $14,462 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.

Financial Results by Reportable Segment The table below reflects the results of the Company’s reportable segments as reviewed by the CODM for fiscal 2017 , 2016 and 2015 . 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 must be included to reconcile the consolidated gross profit presented in the table below to the Company’s consolidated 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): Revenue Gross Profit and Gross Margin Year Ended Year Ended June 25, June 26, 2016 June 28, 2015 June 25, 2017 June 26, 2016 June 28, 2015 Lighting Products $701,467 $889,133 $906,502 $196,218 $238,242 $235,542 Lighting Products gross margin 28 % 27 % 26 % LED Products 550,302 551,156 554,987 151,675 173,814 158,955 LED Products gross margin 28 % 32 % 29 % Wolfspeed 221,231 176,338 171,016 103,465 94,622 99,721 Wolfspeed gross margin 47 % 54 % 58 % Total segment reporting $1,473,000 $1,616,627 $1,632,505 451,358 506,678 494,218 Unallocated costs (16,786 ) (19,604 ) (20,299 ) Consolidated gross profit $434,572 $487,074 $473,919 Consolidated gross margin 30 % 30 % 29 % 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. The following table sets forth the Company’s inventories by reportable segment for the fiscal years ended June 25, 2017 and June 26, 2016 . 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): June 25, 2017 June 26, 2016 Lighting Products $ 145,710 $ 172,261 LED Products 108,297 104,544 Wolfspeed 26,453 21,871 Total segment inventories 280,460 298,676 Unallocated inventories 3,925 4,866 Consolidated inventories $284,385 $303,542 Geographic Information The Company conducts business in several geographic areas.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure	Costs Associated with LED Business Restructuring In June 2015, our Board of Directors approved a plan to restructure the LED Products business. The restructuring reduced excess capacity and overhead in order to improve the cost structure moving forward. The primary components of the restructuring include the planned sale or abandonment of certain manufacturing equipment, facility consolidation and the elimination of certain positions. The restructuring activity ended in the second quarter of fiscal 2016. During fiscal 2016, the company realized $18.8 million in LED restructuring charges which were partially offset by a $1.1 million gain on the sale of long-lived assets related to the restructuring which were sold for a value in excess of their estimated net realizable value during fiscal 2016. The following table summarizes the actual charges incurred (in thousands): Capacity and overhead cost reductions Amounts incurred during fiscal year 2015 Amounts incurred during fiscal year 2016 Cumulative amounts incurred through fiscal year 2016 Affected Line Item in the Consolidated Statements of Loss Loss on disposal or impairment of long-lived assets $42,716 $15,506 $58,222 Loss on disposal or impairment of long-lived assets Severance expense 2,019 264 2,283 Sales, general and administrative expenses Lease termination and facility consolidation costs 1,246 3,079 4,325 Sales, general and administrative expenses Increase in channel inventory reserves 26,479 — 26,479 Revenue, net Increase in inventory reserves 11,091 — 11,091 Cost of revenue, net Total restructuring charges $83,551 $18,849 $102,400 In the table above, the lease termination costs relate to the relocation of certain manufacturing operations from a leased facility in Huizhou, China to a company-owned facility which is also in Huizhou, China.

Basis of Presentation and Changes in Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company, and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year The Company’s fiscal year is a 52 or 53 -week period ending on the last Sunday in the month of June. The Company’s 2017 , 2016 and 2015 fiscal years were 52 -week fiscal years. The Company’s 2018 fiscal year will be a 52 -week fiscal year.
Reclassifications	Reclassifications Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net loss or shareholders’ equity.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (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. The Company evaluates its estimates on an ongoing basis, including those related to revenue recognition, product warranty obligations, valuation of inventories, tax related contingencies, valuation of stock-based compensation, valuation of long-lived and intangible assets, other contingencies and litigation, among others. The Company generally bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates.
Segment Information	Segment Information U.S. GAAP requires segmentation based on an entity’s internal organization and reporting of revenue and operating income based upon internal accounting methods commonly referred to as the “management approach.” Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (CODM), or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it currently has three operating and reportable segments. 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 must be included to reconcile the consolidated gross profit presented in the table below to the Company’s consolidated 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.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of unrestricted cash accounts and highly liquid investments with an original maturity of three months or less when purchased. Cash and cash equivalents are stated at cost, which approximates fair value. The Company holds cash and cash equivalents at several major financial institutions, which often exceed insurance limits set by the Federal Deposit Insurance Corporation (FDIC). The Company has not historically experienced any losses due to such concentration of credit risk.
Investments	Investments Investments in certain securities may be classified into three categories: • Held-to-Maturity – Debt securities that the entity has the positive intent and ability to hold to maturity, which are reported at amortized cost. • Trading – Debt and equity securities that are bought and held principally for the purpose of selling in the near term, which are reported at fair value, with unrealized gains and losses included in earnings. • Available-for-Sale – Debt and equity securities not classified as either held-to-maturity or trading securities, which are reported at fair value with unrealized gains or losses excluded from earnings and reported as a separate component of shareholders’ equity. The Company reassesses the appropriateness of the classification (i.e. held-to-maturity, trading or available-for-sale) of its investments at the end of each reporting period. When the fair value of an investment declines below its original cost, the Company considers all available evidence to evaluate whether the decline is other-than-temporary. Among other things, the Company considers the duration and extent of the decline and economic factors influencing the capital markets. For the fiscal years ended June 25, 2017 , June 26, 2016 , and June 28, 2015 , the Company had no other-than-temporary declines below the cost basis of its investments. The Company utilizes specific identification in computing realized gains and losses on the sale of investments. Realized gains and losses on the sale of investments are reported in other income and expense. Investments in marketable securities with maturities beyond one year may be classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. Other long-term investments consist of the Company's approximately 15% common stock ownership interest in Lextar Electronics Corporation (Lextar), which the Company acquired in December 2014. This investment was accounted for under the equity method from the date of investment until June 2016 when the Company chose for its representative not to stand for re-election as a member of the Lextar board of directors. The Company utilizes the fair value option in accounting for its investment in Lextar. The Company has determined that for its fiscal years ended June 26, 2016 and June 28, 2015, Lextar has met the conditions of a significant subsidiary under Rule 1-02(w) of Regulation S-X for which the Company is required, pursuant to Rule 3-09 of Regulation S-X, to file separate financial statements as an exhibit to its Annual Report on Form 10-K. As such, separate financial statements for Lextar , prepared by Lextar and audited by its independent public accounting firm, are filed as Exhibit 99.1 to the Company's Annual Report.
Inventories	Inventories Inventories are stated at lower of cost or market, with cost determined on a first-in, first-out (FIFO) method or an average cost method; and with market not to exceed net realizable value. The Company writes down its inventory balances for estimates of excess and obsolete amounts. These write-downs are recognized as a component of cost of revenue. At the point of the write-down, a new lower-cost basis for that inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase in that newly established lower-cost basis. The Company recognized charges for write-downs in inventories of $7.3 million , $3.6 million and $15.2 million , for fiscal 2017 , 2016 and 2015 , respectively.
Property and Equipment	Property and Equipment Property and equipment are stated at cost and depreciated on a straight-line basis over the assets’ estimated useful lives. Leasehold improvements are amortized over the lesser of the asset life or the life of the related lease. In general, the Company’s policy for useful lives is as follows: Machinery and equipment 3 to 15 years Buildings and building improvements 5 to 40 years Furniture and fixtures 3 to 5 years Aircraft and vehicles 5 to 20 years Leasehold improvements Shorter of estimated useful life or lease term Expenditures for repairs and maintenance are charged to expense as incurred. The costs for major renewals and improvements are capitalized and depreciated over their estimated useful lives. The cost and related accumulated depreciation of the assets are removed from the accounts upon disposition and any resulting gain or loss is reflected in operating income.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs are included in Cost of revenue, net in the Consolidated Statements of Loss and are recognized as a period expense during the period in which they are incurred.
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company recognizes the assets acquired and liabilities assumed in business combinations at their respective fair values at the date of acquisition, with any excess purchase price recognized as goodwill. Valuation of intangible assets entails significant estimates and assumptions including, but not limited to, estimating future cash flows from product revenue, developing appropriate discount rates, continuation of customer relationships and renewal of customer contracts, and approximating the useful lives of the intangible assets acquired. Goodwill The Company recognizes goodwill as an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The Company tests goodwill for impairment at least annually as of the first day of the fiscal fourth quarter, or when indications of potential impairment exist. The Company monitors for the existence of potential impairment indicators throughout the fiscal year. The Company conducts impairment testing for goodwill at the reporting unit level. Reporting units may be operating segments as a whole or an operation one level below an operating segment, referred to as a component. The Company has determined that its reporting units are its three operating and reportable segments. The Company may initiate goodwill impairment testing by considering qualitative factors to determine whether it is more likely than not that a reporting unit’s carrying value is greater than its fair value. Such factors may include the following, among others: a significant decline in the reporting unit ’ s expected future cash flows; a sustained, significant decline in the Company ’ s stock price and market capitalization; a significant adverse change in legal factors or in the business climate; unanticipated competition; and slower growth rates; as well as changes in management, key personnel, strategy and customers . If the Company’s qualitative assessment indicates that goodwill impairment is more likely than not, the Company performs the two-step goodwill impairment test. Alternatively, the Company may bypass the qualitative test and initiate goodwill impairment testing with the first step of the two-step goodwill impairment test. During the first step of the goodwill impairment test, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company derives a reporting unit ’ s fair value through a combination of the market approach (a guideline transaction method) and the income approach (a discounted cash flow analysis). The income approach utilizes a discount rate from the capital asset pricing model. If all reporting units are analyzed during the first step of the goodwill impairment test, their respective fair values are reconciled back to the Company ’ s consolidated market capitalization. If the fair value of a reporting unit exceeds its carrying value, then the Company concludes that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company performs the second step of the goodwill impairment test to measure possible goodwill impairment loss. During the second step, the Company hypothetically values the reporting unit ’ s tangible and intangible assets and liabilities as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit ’ s goodwill is compared to the carrying value of its goodwill. If the carrying value of the reporting unit ’ s goodwill exceeds the implied fair value of the goodwill, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying value of the reporting unit ’ s goodwill. Once an impairment loss is recognized, the adjusted carrying value of the goodwill becomes the new accounting basis of the goodwill for the reporting unit. Indefinite-Lived Intangible Assets The Company ’ s indefinite-lived intangible assets are tested for impairment at least annually in the fiscal fourth quarter or when indications of potential impairment exist. The Company monitors for the existence of potential impairment indicators throughout the fiscal year. The Company ’ s impairment test may begin with a qualitative test to determine whether it is more likely than not that an indefinite-lived intangible asset ’ s carrying value is greater than its fair value. In performing this test, the Company may consider the following qualitative factors, among others: a significant decline in expected future cash flows; changes in industry and market conditions such as the deterioration in the environment in which the Company operates or an increased competitive environment; changes in management, key personnel, strategy, or customers; as well as other economic factors. If the Company’s qualitative assessment indicates that asset impairment is more likely than not, the Company performs a quantitative impairment test by comparing the fair value of the indefinite-lived intangible asset to its carrying value. Alternatively, the Company may bypass the qualitative test and initiate impairment testing with the quantitative impairment test. Determining the fair value of indefinite-lived intangible assets entails significant estimates and assumptions including, but not limited to, determining the timing and expected costs to complete development projects, estimating future cash flows from product revenue, developing appropriate discount rates, estimating probability rates for the successful completion of development projects, continuation of customer relationships and renewal of customer contracts, and approximating the useful lives of the intangible assets acquired. If the fair value of the indefinite-lived intangible asset exceeds its carrying value, then the Company concludes that no impairment has occurred. If the carrying value of the indefinite-lived intangible asset exceeds its fair value, the Company recognizes an impairment loss in an amount equal to the excess, not to exceed the carrying value. Once an impairment loss is recognized, the adjusted carrying value becomes the new accounting basis of the indefinite-lived intangible asset. Finite-Lived Intangible Assets U.S. GAAP requires that intangible assets, other than goodwill and indefinite-lived intangibles, must be amortized over their useful lives. The Company is currently amortizing its acquired intangible assets with finite lives over periods ranging from one to 20 years . Patent rights reflect costs incurred by the Company in applying for and maintaining patents owned by the Company and costs incurred in purchasing patents and related rights from third parties. Licensing rights reflect costs incurred by the Company in acquiring licenses under patents owned by others. The Company amortizes both on a straight-line basis over the expected useful life of the associated patent rights, which is generally the lesser of 20 years from the date of the patent application or the license period. Royalties payable under licenses for patents owned by others are generally expensed as incurred. The Company reviews its capitalized patent portfolio and recognizes impairment charges when circumstances warrant, such as when patents have been abandoned or are no longer being pursued.
Long-Lived Assets	Long-Lived Assets The Company reviews long-lived assets such as property and equipment for impairment based on changes in circumstances that indicate their carrying amounts may not be recoverable. In making these determinations, the Company uses certain assumptions, including but not limited to: (1) estimations of the fair market value of the assets and (2) estimations of future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used in the Company’s operations and estimated salvage values.
Contingent Liabilities	Contingent Liabilities The Company recognizes contingent liabilities when it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Disclosure in the notes to the financial statements is required for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred. See Note 13 , “Commitments and Contingencies,” for a discussion of loss contingencies in connection with pending and threatened litigation. The Company expenses as incurred the costs of defending legal claims against the Company.
Revenue Recognition	Revenue Recognition The Company recognizes product revenue when the earnings process is complete, as evidenced by persuasive evidence of an arrangement (typically in the form of a purchase order), when the sales price is fixed or determinable, collection of revenue is reasonably assured, and title and risk of loss have passed to the customer. The Company provides its customers with limited rights of return for non-conforming shipments and product warranty claims. The Company estimates an allowance for anticipated sales returns based upon an analysis of historical sales returns and other relevant data. The Company recognizes an allowance for non-conforming returns at the time of sale as a reduction of product revenue and as a reduction to the related accounts receivable balance. The Company recognizes a liability for product warranty claims at the time of sale as an increase to cost of revenue. A substantial portion of the Company’s products are sold through distributors. Distributors stock inventory and sell the Company’s products to their own customer base, which may include: value added resellers; manufacturers who incorporate the Company’s products into their own manufactured goods; or ultimate end users of the Company’s products. The Company recognizes revenue upon shipment of its products to its distributors. This arrangement is often referred to as a “sell-in” or “point-of-purchase” model as opposed to a “sell-through” or “point-of-sale” model, where revenue is deferred and not recognized until the distributor sells the product through to their customer. Certain of the Company’s distributors are provided limited rights that allow them to return a portion of inventory (product exchange rights or stock rotation rights) and receive credits for changes in selling prices (price protection rights) or customer pricing arrangements under the Company’s “ship and debit” program or other targeted sales incentives. These estimates are calculated based upon historical experience, product shipment analysis, current economic conditions, on-hand inventory at the distributor, and customer contractual arrangements. The Company believes that it can reasonably and reliably estimate the allowance for distributor credits at the time of sale. Accordingly, estimates for these rights are recognized at the time of sale as a reduction of product revenue and as a reduction to the related accounts receivable balance. From time to time, the Company will issue a new price book for its products, and provide a credit to certain distributors for inventory quantities on hand if required by the Company’s agreement with the distributor. This practice is known as price protection. These credits are applied against the reserve that the Company establishes upon initial shipment of product to the distributor. Under the ship and debit program, products are sold to distributors at negotiated prices and the distributors are required to pay for the products purchased within the Company’s standard commercial terms. Subsequent to the initial product purchase, a distributor may request a price allowance for a particular part number(s) for certain target customers, prior to the distributor reselling the particular part to that customer. If the Company approves an allowance and the distributor resells the product to the target customer, the Company credits the distributor according to the allowance the Company approved. These credits are applied against the reserve that the Company establishes upon initial shipment of product to the distributor. In addition, the Company runs sales incentive programs with certain distributors and retailers, such as product rebates and cooperative advertising campaigns. The Company recognizes these incentives at the time they are offered to customers and records a credit to their account with an offsetting expense as either a reduction to revenue, increase to cost of revenue, or marketing expense depending on the type of sales incentive. From time to time, the Company may enter into licensing arrangements related to its intellectual property. Revenue from licensing arrangements is recognized when earned and estimable. The timing of revenue recognition is dependent on the terms of each license agreement. Generally, the Company will recognize non-refundable upfront licensing fees related to patent licenses immediately upon receipt of the funds if the Company has no significant future obligations to perform under the arrangement. However, the Company will defer recognition for licensing fees where the Company has significant future performance requirements, the fee is not fixed (such as royalties earned as a percentage of future revenue), or the fees are otherwise contingent.
Accounts Receivable	Accounts Receivable For product revenue, the Company typically invoices its customers at the time of shipment for the sales order value of products shipped. Accounts receivable are recognized at the invoiced amount and are not subject to any interest or finance charges. The Company does not have any off-balance sheet credit exposure related to any of its customers.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company evaluates the collectability of accounts receivable based on a combination of factors. In cases where the Company becomes aware of circumstances that may impair a specific customer’s ability to meet its financial obligations subsequent to the original sale, the Company will recognize an allowance against amounts due, and thereby reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers, the Company recognizes an allowance for doubtful accounts based on the length of time the receivables are past due and consideration of other factors such as industry conditions, the current business environment and the Company’s historical experience.
Advertising	Advertising The Company expenses the costs of producing advertisements at the time production occurs and expenses the cost of communicating the advertising in the period in which the advertising is used. Advertising costs are included in Sales, general and administrative expenses in the Consolidated Statements of Loss and amounted to approximately $13.0 million , $12.6 million , and $25.6 million for the years ended June 25, 2017 , June 26, 2016 and June 28, 2015 , respectively.
Research and Development	Research and Development Research and development activities are expensed when incurred.
Earnings Per Share	Loss Per Share Basic loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding for the applicable period. Diluted loss per share is determined in the same manner as basic loss per share except that the number of shares is increased to assume exercise of potentially dilutive stock options, nonvested restricted stock and contingently issuable shares using the treasury stock method, unless the effect of such increases would be anti-dilutive. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recognized in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for all share-based payments granted based on the fair value of the shares on the date of grant. Compensation expense is then recognized over the award’s vesting period. 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.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Cash and cash equivalents, short-term investments, accounts and interest receivable, accounts payable and other liabilities approximate their fair values at June 25, 2017 and June 26, 2016 due to the short-term nature of these instruments.
Taxes	Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets are recognized for deductible temporary differences, along with net operating loss carryforwards and credit carryforwards, if it is more likely than not that the tax benefits will be realized. To the extent a deferred tax asset cannot be recognized under the preceding criteria, allowances are established. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Taxes payable which are not based on income are accrued ratably over the period to which they apply. For example, payroll taxes are accrued each period end based upon the amount of payroll taxes that are owed as of that date; whereas taxes such as property taxes and franchise taxes are accrued over the fiscal year to which they apply if paid at the end of a period, or they are amortized ratably over the fiscal year if they are paid in advance.
Excise Taxes	Sales Taxes The Company presents sales taxes collected from customers and remitted to governmental authorities on a net basis (i.e. excluded from revenue and expenses).
Foreign Currency Translation	Foreign Currency Translation Foreign currency translation adjustments are recognized in Other comprehensive (loss) income in the Consolidated Statements of Comprehensive Loss for changes between the foreign subsidiaries’ functional currency and the United States (U.S.) dollar. Foreign currency translation gains and losses are included in the Company’s equity account balance of Accumulated other comprehensive income, net of taxes in the Consolidated Balance Sheets until such time that the subsidiaries are either sold or substantially liquidated. Because the Company and its subsidiaries transact business in currencies other than the U.S. Dollar, the Company will continue to experience varying amounts of foreign currency exchange gains and losses for subsidiaries with U.S. dollar functional currency.
Recently Adopted and Issued Accounting Pronouncements	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 Company’s evaluation of ASU 2014-09 is ongoing and not complete; however, the Company anticipates the primary changes to revenue recognition to be related to certain patent license arrangements. The FASB has issued and may issue in the future, interpretive guidance, which may cause our evaluation to change. The effective date will be the first quarter of the Company's fiscal year ending June 30, 2019 and the Company currently expects to use the modified retrospective method. 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 24, 2018. The Company's adoption of this ASU is not expected to impact its consolidated financial statements. 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.
