	Overview
	Cree, Inc. (the Company) is a leading innovator of lighting-class light emitting diode (LED) products, lighting products and semiconductor products for power and radio-frequency (RF) applications. The Company's products are targeted for applications such as indoor and outdoor lighting, video displays, transportation, electronic signs and signals, power supplies, inverters and wireless systems.
	The Company develops and manufactures semiconductor materials and devices primarily based on silicon carbide (SiC), gallium nitride (GaN) and related compounds. In many cases, the properties of SiC and GaN offer technical advantages over traditional silicon, gallium arsenide (GaAs) and other materials used for electronic applications.
	The Company's LED products consist of LED components, LED chips and SiC materials. As LED technology improves, the Company believes the potential market for LED lighting will continue to expand. The Company's success in selling LED products depends upon the ability to offer innovative products and its ability to enable its customers to develop and market LED-based products that successfully compete and drive LED adoption against traditional lighting products.
	The Company's lighting products consist of both LED and traditional lighting systems. The Company designs, manufactures and sells lighting fixtures and lamps for the commercial, industrial and consumer markets.
	In addition, the Company develops, manufactures and sells power and RF devices. The Company's power products are made from SiC and provide increased efficiency, faster switching speeds and reduced system size and weight over comparable silicon-based power devices. The Company's RF devices are made from GaN and provide improved efficiency, bandwidth and frequency of operation as compared to silicon or gallium arsenide.
	The majority of the Company's products are manufactured at its production facilities located in North Carolina, Wisconsin and China. The Company also uses contract manufacturers for certain aspects of product fabrication, assembly and packaging. The Company operates research and development facilities in North Carolina, California, Wisconsin, India and China.
	Cree, Inc. is a North Carolina corporation established in 1987 and is headquartered in Durham, North Carolina.
	As of September 29, 2013, the Company has three reportable segments:
	•	LED Products
	•	Lighting Products
	•	Power and RF Products
	For financial results by reportable segment, please refer to Note 12 "Reportable Segments."
	Basis of Presentation
	The consolidated balance sheet at September 29, 2013, the consolidated statements of income for the three months ended September 29, 2013 and September 23, 2012, the consolidated statements of comprehensive income for the three months ended September 29, 2013 and September 23, 2012, and the consolidated statements of cash flows for the three months ended September 29, 2013 and September 23, 2012 (collectively, the consolidated financial statements) have been prepared by the Company and have not been audited. In the opinion of management, all normal and recurring adjustments necessary to present fairly the consolidated financial position, results of operations and cash flows at September 29, 2013, and for all periods presented, have been made. All significant intercompany accounts and transactions have been eliminated. The consolidated balance sheet at June 30, 2013 has been derived from the audited financial statements as of that date.
	Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2013 (fiscal 2013). The results of operations for the three months ended September 29, 2013 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 29, 2014 (fiscal 2014).
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates.
	Certain fiscal 2013 amounts in the accompanying consolidated financial statements have been reclassified to conform to the fiscal 2014 presentation. These reclassifications had no effect on previously reported consolidated net income or shareholders’ equity.
	New Accounting Standards
	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 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 carryfoward 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 prospectively 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.

Acquisitions	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. See Note 11 “Commitments and Contingencies” for a discussion of the amounts receivable from the Stock Purchase Agreement escrow funds. 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 assets, liabilities and operating results of Ruud Lighting have been included in the Lighting Products segment of the Company’s consolidated financial statements from the date of acquisition and are reflected in all periods presented in the accompanying unaudited consolidated financial statements.

	The Company utilizes specific identification in computing realized gains and losses on the sale of investments. Realized gains from the sale of investments for the three months ended September 29, 2013 of approximately $10 thousand were included in "Non-operating income, net" 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 considers declines in its securities to be temporary in nature, and does not consider its securities to be impaired as of September 29, 2013 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. 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 September 29, 2013, financial assets utilizing Level 1 inputs included money market funds. Financial assets utilizing Level 2 inputs included municipal bonds, corporate bonds, non-U.S. certificates of deposit, U.S. agency securities and non-U.S. government securities. Level 2 assets are valued using a third-party pricing services 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 does not have any significant financial assets requiring the use of Level 3 inputs. There were no transfers between Level 1 and Level 2 during the three months ended September 29, 2013.
	The following table sets forth financial instruments carried at fair value within the U.S. GAAP hierarchy (in thousands):

StockBased_Compensation

Stock-Based Compensation	3 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation
	The Company currently has one equity-based compensation plan, the 2004 Long-Term Incentive Compensation Plan, from which stock-based compensation awards can be granted to employees and directors. In addition, the Company has equity-based compensation plans that have been terminated so that no future grants can be made under these plans, but under which options are currently outstanding.
	Prior to the first quarter of 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.
	The Company also has an Employee Stock Purchase Plan (ESPP) that provides employees with the opportunity to purchase common stock at a discount. The ESPP limits employee contributions to 15% of each employee’s compensation (as defined in the plan). The ESPP allows employees to purchase shares at a 15% discount to the fair market value of common stock on the purchase date during the twelve-month participation period, divided into two equal six-month purchase periods, and provides 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 also provides for an automatic reset feature to start participants on a new twelve-month participation period if the stock price declines during the first six-month purchase period.
	Stock Option Awards
	The following table summarizes option activity during the three months ended September 29, 2013 (shares in thousands):
		Number of Shares		Weighted-Average Exercise Price
	Outstanding at June 30, 2013	8,657			$35.67

	Outstanding at September 29, 2013	10,599			$40.61
	Restricted Stock Awards
	A summary of nonvested restricted stock awards (RSAs) and restricted stock unit awards (RSUs) outstanding under the Company’s 2004 Long-Term Incentive Compensation Plan as of September 29, 2013 and changes during the three months then ended, are as follows (in thousands, except per share data):
		Number of		Weighted-Average

	Nonvested at June 30, 2013	647			$33.80
	Granted	512		54.6
	Vested	(215	)	33.79
	Forfeited	(7	)	35.45
	Nonvested at September 29, 2013	937			$45.16
	Stock-Based Compensation Valuation and Expense
	The Company accounts for its employee stock-based compensation plan 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):

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	The variation between the Company's effective income tax rate and the U.S. statutory rate of 35% is due to a percentage of the Company's projected income for the full year being derived from international locations with lower tax rates than the U.S. and the impact of tax credits available in the current year. A change in the mix of pretax income of the Company's various tax jurisdictions can have a material impact on the Company's periodic effective tax rate.
	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 $10.3 million increase to the liability for unrecognized tax benefits due to uncertainty regarding an application for a method of accounting change for tax purposes filed in August 2013. In addition, there was a $0.7 million decrease to the amount of unrecognized tax benefits following the settlement of prior year tax audits. As a result, the total liability for unrecognized tax benefits as of September 29, 2013 was $12.3 million. If any portion of this $12.3 million is recognized, the Company will then include that portion in the computation of its effective tax rate. Although the ultimate timing of the resolution and/or closure of audits is highly uncertain, the Company believes it is reasonably possible that approximately $1.4 million of gross unrecognized tax benefits will change in the next 12 months as a result of pending audit settlements or statute requirements.
	The Company files U.S. federal, U.S. state and foreign tax returns. For U.S. federal purposes, the Company is generally no longer subject to tax examinations for fiscal years ended June 28, 2009 and prior. 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 2003 and prior. Certain carryforward tax attributes generated in prior years remain subject to examination and adjustment. The Company is currently under audit by the German Federal Central Tax Office for the fiscal year ended June 29, 2008 (fiscal 2008) through the fiscal year ended June 27, 2010 (fiscal 2010). During the first quarter of fiscal 2014, the Company settled its examination with the Hong Kong Inland Revenue Department for fiscal 2008 through fiscal 2010. This settlement resulted in the Company recognizing tax expense of $0.3 million in the first quarter of fiscal 2014, fully offset by a decrease to the amount of unrecognized tax benefits.

	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 September 29, 2013, $942 thousand of the Company's product warranty liabilities were classified as long-term.
	Litigation
	The Company is currently a party to various legal proceedings, including those described in the Company's Annual Report on Form 10-K for fiscal 2013. The following is provided as an update to the Company's legal proceedings as contained in that report. Unless otherwise indicated, the potential losses for claims against the Company in these matters are not reasonably estimable.
	Cooper Lighting Litigation
	Ruud Lighting, Inc. filed a complaint for patent infringement against Cooper Lighting, LLC in the U.S. District Court for the Eastern District of Wisconsin on April 2, 2010. The complaint as amended seeks injunctive relief and damages for infringement of two U.S. patents owned by Ruud Lighting: No. 7,686,469, entitled "LED Lighting Fixture"; and No. 7,891,835, entitled “Light-Directed Apparatus with Protected Reflector-Shield and Lighting Fixture Utilizing Same.” On May 23, 2012, Ruud Lighting filed a second complaint for patent infringement against Cooper Lighting, LLC in the U.S. District Court for the Eastern District of Wisconsin. The complaint seeks injunctive relief and damages for infringement of a third U.S. patent owned by Ruud Lighting, No. 7,952,262, entitled “Modular LED Unit Incorporating Interconnected Heat Sinks Configured To Mount and Hold Adjacent LED Modules." In each of these actions Cooper Lighting has filed an answer and counterclaims in which it denies any infringement and seeks a declaratory judgment that the asserted claims of the patents are invalid. On February 19, 2013, the Company, as successor-in-interest to Ruud Lighting, Inc., filed a third complaint for patent infringement against Cooper Lighting in the U.S. District Court for the Eastern District of Wisconsin. The complaint seeks injunctive relief and damages for infringement of two U.S. patents owned by the Company, No. 8,282,239, entitled “Light-Directing Apparatus with Protected Reflector-Shield and Lighting Fixture Utilizing Same” and No. 8,070,306, entitled “LED Lighting Fixture.”
	Cooper Lighting, LLC filed a complaint for patent infringement against the Company and Ruud Lighting, Inc. in the U.S. District Court for the Northern District of Georgia on September 7, 2012. The complaint seeks injunctive relief and damages for infringement of one U.S. patent owned by Cooper Lighting, LLC: No. 8,210,722, entitled "LED Device for Wide Beam Generation." The Company has filed an answer in which it denies any infringement and asserts that the patent is invalid as well as other defenses.
	Illumination Management Solutions, Inc., a subsidiary of Cooper Lighting, LLC, filed a complaint for patent infringement against Ruud Lighting in the U.S. District Court for the Eastern District of Texas on June 7, 2010. The action was later transferred to the U.S. District Court for the Eastern District of Wisconsin. As amended in January 2012, the complaint alleged that Ruud Lighting is infringing two U.S. patents owned by Illumination Management Solutions, No. 7,674,018 and No. 7,993,036, each entitled "LED Device for Wide Beam Generation." It also alleged that Ruud Lighting and its then president, Alan Ruud, who served on the plaintiff's board of directors in 2006 and 2007 when Ruud Lighting was a shareholder of the plaintiff, conspired to misuse confidential information obtained from the plaintiff to file patent applications and to obtain patents assigned to Ruud Lighting. The complaint sought injunctive relief, damages and ownership of the patent applications and patents alleged to have been wrongfully filed and obtained. The court in October 2012 granted partial summary judgment in favor of Ruud Lighting, finding that most of the accused products did not infringe either of the asserted patents. The court in February 2013 entered final judgment in which the court 1) dismissed the claims relating to most of the accused products, finding that they did not infringe either of the asserted patents; 2) dismissed with prejudice and with the consent of the parties the claims with respect to the remaining accused products; 3) severed the conspiracy claim, which was subsequently voluntarily dismissed; and 4) dismissed the remaining claims and counterclaims without prejudice. In March 2013, the plaintiffs filed a notice of appeal from this judgment to the U.S. Court of Appeals for the Federal Circuit.
	Ruud Lighting is a defendant in an action commenced by Illumination Management Solutions in the U.S. District Court for the Central District of California on June 8, 2010 and later transferred to the U.S. District Court for the Eastern District of Wisconsin. As amended in January 2013, the complaint names as defendants Ruud Lighting and two of its employees, Alan Ruud and Christopher Ruud, and asserts that the defendants engaged in wrongful acts arising out of the relationship between the plaintiff and Ruud Lighting in 2006 and 2007 when Ruud Lighting was a shareholder of the plaintiff and Alan Ruud served on the plaintiff's board of directors. The complaint alleges that the defendants breached fiduciary duties and otherwise acted improperly by pursuing a plan to compete with the plaintiff and that the defendants misused information obtained from the plaintiff as fiduciaries and subject to a non-disclosure agreement. These allegedly wrongful acts included filing patent applications and obtaining patents assigned to Ruud Lighting on inventions claimed by the plaintiff. The complaint also alleges that Ruud Lighting: 1) marketed its LED products without reference to certain optical technology claimed by the plaintiff, thereby breaching a marketing agreement with the plaintiff and engaging in unfair competition and false advertising; and 2) breached the marketing agreement by failing to give the plaintiff a right of first refusal to integrate the plaintiff's optical technology into Ruud Lighting LED products. The complaint further alleges that the plaintiff is entitled to a correction of the inventors named in one or more patents to add a founder of the plaintiff as an inventor. The complaint seeks to recover damages, all profits and other gains realized by defendants as a result of the acts complained of, attorneys' fees, ownership of any interest in the patent applications and patents alleged to have been wrongfully filed and obtained, and correction of the named inventors on one or more patents.
	In September 2013, the Company and the Cooper Lighting and Illumination Management Solutions parties reached a binding term sheet agreement to settle all six cases. This non-cash settlement agreement provides for a royalty-free cross license of all of the patents-in-suit in the six cases for the life of the patents; a royalty-free cross license of each of the Company’s and Cooper Lighting’s LED luminaire patent portfolios for 7 years (with carve-outs of the Company’s LED chip, LED component and LED replacement lamp patents from the cross license, as well as carve-outs for certain LED luminaires of Cooper Lighting that are not for general illumination); and a supply agreement, with no minimum purchase commitment and with a 7 year term, whereby the Company may sell Cooper Lighting LED components and modules. The parties are negotiating the terms of the definitive agreements to effect this binding agreement. The Company recorded a $17.4 million non-cash litigation settlement charge in the first quarter of fiscal 2014, representing the current estimated fair value of the patent licenses to be provided to the Cooper Lighting and Illumination Management Solutions parties in excess of the fair value patent license rights to be received by the Company under the terms of the proposed cross license agreement. This $17.4 million obligation will be amortized into income over the reminder of the 7 year license period.
	In conjunction with the September 2013 settlement with the Cooper Lighting and Illumination Management Solutions parties, the Company also recorded a $17.4 million offset to the non-cash litigation charge to reflect the amount receivable by the Company from the Stock Purchase Agreement escrow funds, including cash and common stock consideration, pursuant to a letter agreement approved by the Audit Committee, which the Company entered into during September 2013 with Christopher Ruud, acting as the Seller Representative for the former Ruud Lighting shareholders. The escrow consideration will be provided to the Company upon the execution of the final settlement agreement with the Cooper Lighting and Illumination Management Solutions parties.
	The Fox Group Litigation
	The Fox Group, Inc. filed a complaint for patent infringement against the Company in the U.S. District Court for the Eastern District of Virginia on June 29, 2010. The complaint, which sought injunctive relief and damages, asserted that the Company was infringing two U.S. patents relating to high quality silicon carbide material: No. 6,534,026, entitled "Low Defect Density Silicon Carbide" (the "'026 patent"); and No. 6,562,130, entitled "Low Defect Axially Grown Single Crystal Silicon Carbide" (the "'130 patent"). The district court granted summary judgment in favor of the Company in August 2011. The court determined that the Company did not infringe the '026 patent and that the claims of the '130 patent asserted against the Company are invalid. The Fox Group appealed the decision to the U.S. Court of Appeals for the Federal Circuit, which affirmed the judgment. The Fox Group's petition for a rehearing with the Federal Circuit was denied in February 2013 and the Fox Group filed a writ of certiorari with the U.S. Supreme Court in May 2013. The U.S. Supreme court denied the writ of certiorari on October 15, 2013, thereby exhausting the Fox Group’s appeals in this matter.

Segment Reporting [Abstract]
Reportable Segments	Reportable Segments
	The Company's operating and reportable segments are:
	•	LED Products
	•	Lighting Products
	•	Power and RF Products
	Reportable Segments Description
	The Company's LED Products segment includes LED chips, LED components and SiC materials. The Company's Lighting Products segment consists of both LED and traditional lighting systems, with its primary focus on LED lighting. The Company's Power and RF Products segment includes power devices and RF devices.
	Financial Results by Reportable Segment
	The table below reflects the results of the Company's reportable segments as reviewed by the Chief Operating Decision Maker (CODM) for the three months ended September 29, 2013 and September 23, 2012. The Company's CODM is the Chief Executive Officer. The Company uses substantially 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 revenue when evaluating segment performance and allocating resources to each segment. Thus, inter-segment revenue is not included in the segment revenues 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. Inventory is normally transferred between the Company's reportable segments at cost. However, due to the vertically-integrated nature of the Company's business and the fixed cost nature of the Company's manufacturing operations, the Company will apportion, as necessary, lower of cost or market write-downs on products among the segments involved in producing the products. The lower of cost or market write-down is apportioned based on each segment's proportional production cost and is reported as an increase to each segment's cost of revenue. The Company's CODM evaluates segment performance and resource allocation after apportionment of any lower of cost or market write-downs.
	Unallocated costs in the table below are not reviewed by the Company's CODM when evaluating segment performance and allocating resources to each segment. These unallocated costs consist primarily of manufacturing employees' stock-based compensation, expenses for profit sharing and quarterly or annual incentive plans, matching contributions under the Company's 401(k) plan and acquisition related costs.
	Revenues, gross profit and gross margin for each of the Company's segments were as follows (in thousands, except percentages):

These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2013 (fiscal 2013). The results of operations for the three months ended September 29, 2013 are not necessarily indicative of the operating results that may be attained for the entire fiscal year ending June 29, 2014 (fiscal 2014).
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual amounts could differ materially from those estimates.
	Certain fiscal 2013 amounts in the accompanying consolidated financial statements have been reclassified to conform to the fiscal 2014 presentation. These reclassifications had no effect on previously reported consolidated net income or shareholders’ equity.

	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 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 carryfoward 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 prospectively 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.
Stock-Based Compensation Valuation and Expense	Stock-Based Compensation Valuation and Expense
	The Company accounts for its employee stock-based compensation plan 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.
