	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 2014 and 2012 fiscal years were 52-week fiscal years and the 2013 fiscal year was a 53-week fiscal year. The Company’s 2015 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 income 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 29, 2014, June 30, 2013, and June 24, 2012, 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.
	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 $5.2 million, $12.5 million and $14.7 million, for fiscal 2014, 2013 and 2012, 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 Income 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. 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 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 12, “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 Income and amounted to approximately $26.6 million, $18.2 million, and $9.7 million for the years ended June 29, 2014, June 30, 2013 and June 24, 2012, respectively.
Research and Development
Research and development activities are expensed when incurred. For contracts under which the Company anticipates that direct costs will exceed amounts to be funded over the life of the contract, costs are reported as Research and development expenses in the Consolidated Statements of Income when incurred, and related funding as an offset of those expenses when funds are received.
Earnings Per Share
Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding for the applicable period. Diluted earnings per share is determined in the same manner as basic earnings 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 29, 2014 and June 30, 2013 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.
Excise 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 income (loss) in the Consolidated Statements of Comprehensive Income 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 Accounting Pronouncements
Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward or Tax Credit Carryforward Exists
In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists. The ASU provides guidance regarding the presentation in the statement of financial position of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. The ASU generally provides that an entity’s unrecognized tax benefit, or a portion of its unrecognized tax benefit, should be presented in its financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The ASU applies retrospectively to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date, and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company early adopted this guidance beginning with the first quarter of fiscal 2014. The Company’s adoption of this guidance did not have a significant impact on its consolidated financial statements.
Recently Issued Accounting Pronouncements
Revenue from Contracts with Customers
In May 2014, the FASB issued ASU No. 2014-09: Revenue from Contracts with Customers (Topic 606). The ASU establishes a principles-based approach for accounting for revenue arising from contracts with customers and supersedes existing revenue recognition guidance. The ASU provides that an entity should apply a five-step approach for recognizing revenue, including (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. Also, the entity must provide various disclosures concerning the nature, amount and timing of revenue and cash flows arising from contracts with customers. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early application is not permitted. The Company is currently analyzing the impact of this new accounting guidance.

	Acquisitions
	On August 17, 2011, the Company entered into a Stock Purchase Agreement with all of the shareholders of Ruud Lighting, Inc. (Ruud Lighting). Pursuant to the terms of the Stock Purchase Agreement and concurrently with the execution of the Stock Purchase Agreement, the Company acquired all of the outstanding share capital of Ruud Lighting in exchange for consideration consisting of 6.1 million shares of the Company’s common stock valued at approximately $211.0 million and $372.2 million cash, subject to certain post-closing adjustments. Following the acquisition, the Company recorded certain post-closing purchase price adjustments resulting in a $2.3 million reduction to the purchase price and a total purchase price of approximately $666.0 million. The acquisition allowed the Company to expand its product portfolio into outdoor LED lighting.
	Prior to the Company completing its acquisition of Ruud Lighting, Ruud Lighting completed the re-acquisition of its e-conolight business by purchasing all of the membership interests of E-conolight LLC (E-conolight). Ruud Lighting previously sold its e-conolight business in March 2010 and had been providing operational services to E-conolight since that date. In connection with the stock purchase transaction with Ruud Lighting, the Company funded Ruud Lighting’s re-acquisition of E-conolight and repaid Ruud Lighting’s outstanding debt in the aggregate amount of approximately $85.0 million.
	The amounts of revenue, operating loss and net loss of Ruud Lighting in the Consolidated Statements of Income from and including August 17, 2011 to June 24, 2012 were as follows (in thousands, except per share data):
		Since acquisition date to
		June 24,
		2012
	Revenue		$204,353
	Operating loss	(1,985		)
	Net loss	(2,334		)
	Basic net loss per share		($0.02	)
	Diluted net loss per share		($0.02	)
	The following unaudited pro forma information presents a summary of the Company’s consolidated results of operations as if the Ruud Lighting acquisition occurred at the beginning of the fiscal year ended June 24, 2012 (in thousands, except per share data).
		Fiscal Year Ended
		June 24,
		2012
	Revenue		$1,194,990
	Operating income	37,551
	Net income	42,399
	Earnings per share, basic		$0.37
	Earnings per share, diluted		$0.37
	The total revenue for Ruud Lighting included in the pro forma table above was $235.8 million for the year ended June 24, 2012. This amount has been calculated after applying the Company’s accounting policies and adjusting the results of Ruud Lighting to give effect to events that are directly attributable to the Ruud Lighting acquisition, including the elimination of revenue from Ruud Lighting prior to acquisition, additional depreciation and amortization that would have been charged assuming the fair value adjustments (primarily to property and equipment and intangible assets) had been applied at the beginning of the 2012 fiscal year, together with the consequential tax effects. Excluded from the pro forma net income and the earnings per share amounts for the year ended June 24, 2012 are one-time transaction costs attributable to the Ruud Lighting acquisition of $3.1 million. These transaction costs were included in Sales, general and administrative expense in the Consolidated Statements of Income. This supplemental pro forma information has been prepared for comparative purposes and does not purport to be indicative of what would have occurred had the acquisition been made at the beginning of the 2012 fiscal year, nor is it indicative of any future results. Ruud Lighting is included in the Lighting Products segment.

Realized gains from the sale of investments for the fiscal year ended June 29, 2014 of $68 thousand were included in Non-operating income, net in the Consolidated Statements of Income 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 29, 2014 and June 30, 2013.

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. As of June 29, 2014, financial assets utilizing Level 1 inputs included money market funds, and financial assets utilizing Level 2 inputs included municipal bonds, corporate bonds, U.S. agency securities, non-U.S. certificates of deposit and non-U.S. government securities. Level 2 assets are valued 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 29, 2014. There were no transfers between Level 1 and Level 2 during the year ended June 29, 2014.

Shareholders' Equity	'
	Shareholders’ Equity
	In August 2011, in connection with the acquisition of Ruud Lighting, the Company issued 6.1 million shares of common stock valued at approximately $211.0 million. The shares issued in connection with the acquisition were subject to certain transfer restrictions under the Stock Purchase Agreement that lapsed with respect to 25% of the shares held at the completion of each of the following four successive six-month periods, such that all restrictions had lapsed by the second anniversary of the closing.
	On May 6, 2014, the Board of Directors (the Board) approved an increase in the amount of the Company’s stock repurchase program. Pursuant to the program, the Company is now authorized to repurchase shares of its common stock having an aggregate purchase price not exceeding $300 million for all purchases from June 20, 2013 through the new expiration of the program on June 28, 2015.
	During the fourth quarter of fiscal 2014, the Company repurchased 2.1 million shares of its common stock under the program at an average price of $47.11 per share with an aggregate value of $99.6 million. After the repurchase, $200.4 million in aggregate purchase price value remained available under the Company’s stock repurchase program. The repurchase program can 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. Since the inception of the predecessor stock repurchase program in January 2001, the Company has repurchased 12.4 million shares of its common stock at an average price of $24.57 per share with an aggregate value of $305.1 million.
	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 carry stock purchase rights under the plan. The rights plan is 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. Unless terminated by the Board, the rights become exercisable based upon certain limited conditions related to acquisitions of stock, tender offers and certain business combinations involving the Company. The shareholder rights plan includes a review mechanism requiring the independent members of the Board to review and evaluate the plan at least every three years to consider whether the maintenance of the plan continues to be in the best interests of the Company and its shareholders and to communicate their conclusion to the Board. The Board has delegated this responsibility to the Governance and Nominations Committee, which is composed of all independent directors of the Board. On April 24, 2012, the shareholder rights plan was amended and restated to, among other things, extend the expiration date from June 10, 2012 to September 30, 2018, and to remove provisions in the rights plan stipulating that certain actions can be taken only with the concurrence of a majority of the members of the Board who are not affiliated with an acquiring person (more specifically, those who are “Continuing Directors,” as defined in the original rights plan adopted in 2002). On January 29, 2013, the shareholder rights plan was amended solely to change the expiration date from September 30, 2018 to April 24, 2017.
	At June 29, 2014, the Company had reserved a total of approximately 19.0 million shares of its common stock and 0.2 million shares of its Series A preferred stock for future issuance as follows (in thousands):
		Number of
		Shares
	For exercise of outstanding common stock options	8,922

	Stock-Based Compensation
	Overview of Employee Stock-Based Compensation Plans
	Prior to the second quarter of fiscal 2014, the Company had one equity-based compensation plan, the 2004 Long-Term Incentive Compensation Plan (2004 LTIP), from which stock-based compensation awards could be granted to employees and directors. The Company’s 2013 Long-Term Incentive Compensation Plan (2013 LTIP) became effective in the second quarter of fiscal 2014, and replaced the 2004 LTIP as the sole plan for providing stock-based compensation awards to employees and directors on January 1, 2014. The 2004 LTIP has been terminated as to future grants although outstanding awards under the 2004 LTIP will continue to be governed by that plan. In addition, 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 options are currently outstanding.
	Prior to fiscal 2013, the Company’s stock-based awards had been service-based only.  Beginning in fiscal 2013, the Company issued grants of awards that also contain performance-based conditions.  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 2013 Long-Term Incentive Compensation Plan 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. As of June 29, 2014, there were 7.3 million shares authorized for issuance under the plan and 7.2 million shares remaining for future grants. Awards issued under the plan to date include non-qualified stock options, restricted stock, restricted stock units, performance shares and performance units.
	The Company also has an Employee Stock Purchase Plan (ESPP) that provides employees with the opportunity to purchase common stock at a discount. As of June 29, 2014, there were 4.5 million shares authorized for issuance under the ESPP, as amended, with 2.2 million shares remaining for future issuance. The ESPP limits employee contributions to 15% of each employee’s compensation (as defined in the plan) and originally allowed 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 was amended in the second quarter of fiscal 2012 to increase the six-month participation period to a twelve-month participation period, divided into two equal six-month purchase periods, and to provide for a look-back feature. At the end of each six-month period in April and October, employees participating in the plan 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 amendment 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.

	As of June 29, 2014, there was $25.7 million of unrecognized compensation cost related to nonvested awards, which is expected to be recognized over a weighted average period of 3.48 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 currently 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):

Expected volatility	44.5	%	56.8	%		51.7	%
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.

During the second quarter of fiscal 2014, the Company was notified by the Internal Revenue Service that it had been allocated up to $30 million of federal tax credits as part of the American Recovery and Reinvestment Act of 2009 - Phase II (Internal Revenue Code Section 48C). This $30 million allocation is in addition to the $39 million previously allocated to the Company in the third quarter of fiscal 2010. The $30 million allocation was based upon the Company’s plan to place into service approximately $100 million of qualified equipment at its U.S. manufacturing locations from fiscal 2013 through fiscal 2017. Property placed into service during fiscal 2013 generated $15 million of the potential $30 million Internal Revenue Code Section 48C credit. The remaining $15 million of Internal Revenue Code Section 48C credit was generated during the first three quarters of fiscal 2014. The tax benefit (net of related basis adjustments) will be amortized into income over the useful life (5 years ) of the underlying equipment that was placed into service to generate these credits. Since fiscal 2010, the Company has recognized an income tax benefit of $26.1 million related to the credits generated to date, with $11.3 million of this amount recognized as a tax benefit for the year ended June 29, 2014.
As of June 29, 2014 the Company had approximately $15.5 million of state net operating loss carryovers for which a full valuation allowance has been recognized. Additionally, the Company had $4.6 million of state income tax credit carryforwards. Both the state net operating loss carryovers and the state income tax credit carryforwards will begin to expire in fiscal 2017. Furthermore, the Company had approximately $0.8 million of alternative minimum tax credit carryforwards, $9.6 million of 48C credit carryforwards, $2.1 million of research and development credit carryforwards and $1.8 million of state income tax credit carryforwards that relate to excess stock option benefits which, if and when realized, will be recognized in Additional paid-in-capital in the Consolidated Balance Sheets.
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 30, 2013 the Company’s liability for unrecognized tax benefits was $2.7 million. The Company recognized a $18.0 million increase to the liability for unrecognized tax benefits due to uncertainty regarding a change in tax depreciation methodology adopted in the first quarter of fiscal 2014. In addition there was a $2.3 million decrease to the amount of unrecognized tax benefits following the settlement of prior year tax audits and statute expirations. As a result, the total liability for unrecognized tax benefits as of June 29, 2014 was $18.4 million. If any portion of this $18.4 million is recognized, the Company will then include that portion in the computation of its effective tax rate. Although the ultimate timing of the resolution and/or closure of audits is highly uncertain, the Company believes it is reasonably possible that approximately $0.2 million of gross unrecognized tax benefits will change in the next 12 months as a result of pending audit settlements or statute requirements.
The following is a tabular reconciliation of the Company’s change in uncertain tax positions (in thousands):

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 2011. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2010. For foreign purposes, the Company is generally no longer subject to examination for tax periods 2004 and prior. Certain carryforward tax attributes generated in prior years remain subject to examination and adjustment. During the first quarter of fiscal 2014, the Company received a final assessment of $0.3 million from the Hong Kong Inland Revenue Department, representing closure of the audit for fiscal 2008 through fiscal 2010. The assessment was fully offset by a decrease to the amount of unrecognized tax benefits. During the third quarter of fiscal 2014, the Company settled its examination with the German Federal Central Tax Office for fiscal 2008 through fiscal 2010, resulting in an immaterial amount of additional 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 29, 2014, U.S. income taxes were not provided for on a cumulative total of approximately $320.8 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 ended June 30, 2013 and June 29, 2014, the Company did not meet the requirements for the tax holiday, and as such, no benefit has been recognized. In the fiscal year ended June 24, 2012 the Company’s net income increased by $2.1 million ($0.02 per basic share and $0.02 per diluted share), as a result of this arrangement.

	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 warranty reserves, which are primarily related to Lighting Products, are evaluated on a quarterly basis 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 29, 2014, $1.0 million of the Company’s product warranty liabilities were classified as long-term.
	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 May 2022. 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 $5.8 million, $4.8 million and $4.6 million for each of the fiscal years ended June 29, 2014, June 30, 2013 and June 24, 2012, respectively. Certain agreements require that the Company pay property taxes and general property maintenance in addition to the minimum rental payments.

	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.  Unless otherwise indicated, the outcomes in these matters are not reasonably estimable.

The Company's foundry service allows a customer to design its own custom RF circuits to be fabricated in the Company's foundry, or have the Company design and fabricate custom products that meet the customer's specific requirements.
	Financial Results by Reportable Segment
	The table below reflects the results of the Company’s reportable segments as reviewed by the Company’s CODM for fiscal 2014, 2013 and 2012. The Company used the same accounting policies to derive the segment results reported below as those used in the Company’s consolidated financial statements.
	The Company’s CODM does not review inter-segment transactions when evaluating segment performance and allocating resources to each segment, and inter-segment transactions are not included in the segment revenue presented in the table below. As such, total segment revenue in the table below is equal to the Company’s consolidated revenue.
	The Company’s CODM reviews gross profit as the lowest and only level of segment profit. As such, all items below gross profit in the Consolidated Statements of Income must be included to reconcile the consolidated gross profit presented in the table below to the Company’s consolidated income 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

	Consolidated gross margin										38		%	38		%	35		%
	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 following table sets forth the Company’s inventories by reportable segment for the fiscal years ended June 29, 2014 and June 30, 2013.
	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.
	The Company does not allocate assets other than inventories to the reportable segments because the Company’s CODM does not review them when assessing segment performance and allocating resources. The CODM reviews all of the Company’s assets other than inventories on a consolidated basis. Inventories for each of the Company's segments were as follows (in thousands):
		June 29, 2014			June 30, 2013
	LED Products		$123,249			$99,835

	Retirement Savings Plan
	The Company sponsors one employee benefit plan (the 401(k) Plan) pursuant to Section 401(k) of the Internal Revenue Code of 1986, as amended. All U.S. employees are eligible to participate under the 401(k) Plan on the first day of a new fiscal month after the date of hire. Under the 401(k) Plan, there is no fixed dollar amount of retirement benefits; rather, the Company matches a defined percentage of employee deferrals, and employees vest in these matching funds over time. Employees choose their investment elections from a list of available investment options. During the fiscal years ended June 29, 2014, June 30, 2013 and June 24, 2012, the Company contributed approximately $6.3 million, $6.2 million and $4.7 million to the 401(k) Plan, respectively.

	On August 17, 2011, in connection with the Company’s acquisition of Ruud Lighting, two of the prior shareholders of Ruud Lighting, Alan Ruud and Christopher Ruud, executed offer letters for continued employment with Ruud Lighting. Also on August 17, 2011, subsequent to the Company’s acquisition of Ruud Lighting and pursuant to an Aircraft Purchase and Sale Agreement and a Joint Ownership Agreement with Ruud Lighting, each of Alan Ruud (through LSA, LLC, a limited liability company of which Alan Ruud is the sole member (LSA)) and Christopher Ruud (through Light Speed Aviation, LLC, a limited liability company of which Christopher Ruud is the sole member (Light Speed)) acquired a 10% interest in an aircraft previously purchased by Ruud Lighting, resulting in the Company owning an 80% interest in the aircraft. Each of LSA and Light Speed acquired its ownership in the aircraft for a purchase price of approximately $0.9 million for a combined interest of 20% or $1.9 million which is included in Purchase of acquired business, net of cash acquired in the Consolidated Statements of Cash Flows as cash provided by investing activities. On June 25, 2014, the Company acquired the combined 20% interest in the aircraft from LSA and Light Speed for $1.5 million, resulting in the Company having 100% ownership of the aircraft.
	Pursuant to the Joint Ownership Agreement, each of LSA and Light Speed was responsible for its share of flight crew, direct, fixed and other expenses attributable to the aircraft. During fiscal 2014, the Company billed LSA and Light Speed $234 thousand and $697 thousand, respectively.

Subsequent Events	'
	Subsequent Events
	Credit Agreement with Wells Fargo Bank, National Association
	On August 12, 2014, the Company entered into a credit agreement and a line of credit note (collectively, Credit Agreement) with Wells Fargo Bank, National Association, as lender.
	The Credit Agreement provides for a $150 million unsecured revolving line of credit, under which the Company may borrow, repay and reborrow loans from time to time prior to its scheduled maturity date of August 12, 2017 (Maturity Date). Proceeds of loans made under the Credit Agreement may be used for working capital, capital expenditures, acquisitions and other general corporate purposes. The Company may prepay the loans under the Credit Agreement in whole or in part at any time without premium or penalty, subject to customary breakage costs. The Company’s existing and future material domestic subsidiaries are required to guarantee its obligations under the Credit Agreement.
	The loans bear interest, at the Company’s option, at either a daily one month London Interbank Offered Rate (LIBOR) rate or a LIBOR rate, each as determined in accordance with the Credit Agreement, and in each case plus a spread of 0.70% to 1.45% (depending on a ratio of funded debt to Earnings Before Interest Taxes Depreciation and Amortization (EBITDA) as determined in accordance with the Credit Agreement). Principal, together with all accrued and unpaid interest, is due and payable on the Maturity Date. The default rate under the Credit Agreement is an additional 4% per annum over the otherwise applicable rate.
	The Company is also obligated to pay a quarterly fee, payable in arrears, based on the daily unused amount of the line of credit at a rate of 0.08% to 0.18%, with such rate determined based on the ratio described above.
	The Credit Agreement contains customary affirmative and negative covenants, including the required compliance with financial covenants described below, as well as customary events of default. The Credit Agreement requires the Company to maintain a ratio of consolidated funded indebtedness to EBITDA equal to or less than 3.00 to 1.00, and a ratio of consolidated EBITDA to interest expense greater than or equal to 3.00 to 1.00, in each case determined in accordance with the Credit Agreement.
	Agreements with Lextar Electronics Corporation
	On August 26, 2014, the Company and Lextar Electronics Corporation (Lextar) entered into an agreement whereby the Company will make an investment in Lextar and the companies will enter into a supply agreement for sapphire-based LED chips. As part of the agreement, the Company will invest approximately $83 million to purchase 83 million Lextar shares at a price of NT$30 per share. Lextar and the Company will also enter into a long-term LED chip supply agreement, as well as a royalty-bearing license agreement for certain Cree LED chip and component intellectual property. Upon closing of the investment, the Company will own approximately 13% of Lextar.
	The agreement has been approved by the boards of directors of both companies, and is targeted to close in the second quarter of fiscal 2015, subject to the approval of Lextar’s shareholders and the Taiwan Investment Committee, and other customary closing conditions.

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 2014 and 2012 fiscal years were 52-week fiscal years and the 2013 fiscal year was a 53-week fiscal year. The Company’s 2015 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 income 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 table below reflects the results of the Company’s reportable segments as reviewed by the Company’s CODM for fiscal 2014, 2013 and 2012. The Company used the same accounting policies to derive the segment results reported below as those used in the Company’s consolidated financial statements.
	The Company’s CODM does not review inter-segment transactions when evaluating segment performance and allocating resources to each segment, and inter-segment transactions are not included in the segment revenue presented in the table below. As such, total segment revenue in the table below is equal to the Company’s consolidated revenue.
	The Company’s CODM reviews gross profit as the lowest and only level of segment profit. As such, all items below gross profit in the Consolidated Statements of Income must be included to reconcile the consolidated gross profit presented in the table below to the Company’s consolidated income 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 29, 2014, June 30, 2013, and June 24, 2012, 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.
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 $5.2 million, $12.5 million and $14.7 million, for fiscal 2014, 2013 and 2012, 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 Income 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. 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 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 12, “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 Income and amounted to approximately $26.6 million, $18.2 million, and $9.7 million for the years ended June 29, 2014, June 30, 2013 and June 24, 2012, respectively.
Research and Development	'
	Research and Development
	Research and development activities are expensed when incurred. For contracts under which the Company anticipates that direct costs will exceed amounts to be funded over the life of the contract, costs are reported as Research and development expenses in the Consolidated Statements of Income when incurred, and related funding as an offset of those expenses when funds are received.
Earnings Per Share	'
	Earnings Per Share
	Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding for the applicable period. Diluted earnings per share is determined in the same manner as basic earnings 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 currently 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 29, 2014 and June 30, 2013 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	'
	Excise 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 income (loss) in the Consolidated Statements of Comprehensive Income 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.

	In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists. The ASU provides guidance regarding the presentation in the statement of financial position of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. The ASU generally provides that an entity’s unrecognized tax benefit, or a portion of its unrecognized tax benefit, should be presented in its financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The ASU applies retrospectively to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date, and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company early adopted this guidance beginning with the first quarter of fiscal 2014. The Company’s adoption of this guidance did not have a significant impact on its consolidated financial statements.
	Recently Issued Accounting Pronouncements
	Revenue from Contracts with Customers
	In May 2014, the FASB issued ASU No. 2014-09: Revenue from Contracts with Customers (Topic 606). The ASU establishes a principles-based approach for accounting for revenue arising from contracts with customers and supersedes existing revenue recognition guidance. The ASU provides that an entity should apply a five-step approach for recognizing revenue, including (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. Also, the entity must provide various disclosures concerning the nature, amount and timing of revenue and cash flows arising from contracts with customers. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early application is not permitted. The Company is currently analyzing the impact of this new accounting guidance.
