1. Business, Basis of Presentation and Summary of Significant Accounting Policies

Business

International Rectifier Corporation ("IR" or the "Company") designs, manufactures and markets power management semiconductors.  Power management semiconductors address the core challenges of power management, power performance and power conservation, by increasing system efficiency, allowing more compact end-products, improving features on electronic devices and prolonging battery life.

Power semiconductors convert raw power from an electrical outlet, a battery, an alternator running off an internal combustion engine, a hybrid electric vehicle ("HEV") or electric vehicle ("EV"), or other renewable energy sources into more efficient and useful power for a wide range of electrical and electronic systems and equipment. The more sophisticated the end product, the greater the need for specially-formatted, finely-regulated power. The importance of power semiconductor technology rises with the increasing complexity of electronic products and the proliferation of electronic features in information technology, industrial, consumer, aerospace and defense and automotive products.

With the demand for energy usage increasing worldwide and energy costs generally rising, governments and consumers alike are striving to conserve energy and demand more efficient uses of power in all types of electronic products including computers, appliances, military aircraft, and hybrid cars. The information technology, industrial, computing, consumer, high reliability and automobile industries use power management semiconductors to promote energy efficiency and improve performance metrics.  Power management semiconductors enable energy savings by delivering the power tailored for a particular electrical device, rather than delivering a constant stream of power.

The Company's products include power metal oxide semiconductor field effect transistors ("MOSFETs"), high voltage analog and mixed signal integrated circuits ("HVICs"), low voltage analog and mixed signal integrated circuits ("LVICs"), digital integrated circuits ("ICs"), radiation‑resistant ("RAD-Hard") power MOSFETs, insulated gate bipolar transistors ("IGBTs"), high reliability DC-DC converters, digital controllers, integrated power modules, and automotive product packages.

Basis of Presentation

The condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"), and therefore do not include all information and notes normally provided in audited financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, which are located in North America, Europe and Asia. Intercompany balances and transactions have been eliminated in consolidation.

In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation of the Company's results of operations, financial position, and cash flows have been included.  The results of operations for the interim periods presented are not necessarily comparable to the results of operations for any other interim period or indicative of the results that will be recorded for the full fiscal year ending June 30, 2013. These condensed consolidated financial statements and the accompanying notes should be read in conjunction with the Company's annual consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended June 24, 2012 filed with the SEC on August 23, 2012 (the "2012 Annual Report").

Fiscal Year and Quarter

The Company operates on a 52-53 week fiscal year with the fiscal year ending on the last Sunday in June. The three months ended March 2013 and 2012 consisted of 13 weeks ending on March 24, 2013 and March 25, 2012, respectively.  The current fiscal year will consist of 53 weeks and end on June 30, 2013.

Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported revenues and expenses during the reporting period. Actual results could differ from those estimates.

Subsequent Events

The Company evaluates events subsequent to the end of the fiscal quarter through the date the financial statements are filed with the SEC for recognition or disclosure in the consolidated financial statements.  Events that provide additional evidence about material conditions that existed at the date of the balance sheet are evaluated for recognition in the consolidated financial statements.  Events that provide evidence about conditions that did not exist at the date of the balance sheet but occurred after the balance sheet date are evaluated for disclosure in the notes to the consolidated financial statements.

Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  Assets and liabilities measured at fair value are categorized based on whether the inputs are observable in the market and the degree to which the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels (with Level 3 being the lowest) defined as follows:

· Level 1—Inputs are based on quoted market prices for identical assets or liabilities in active markets at the measurement date.

· Level 2—Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.

· Level 3—Inputs include management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument's valuation.

The financial assets and liabilities which are measured and recorded at fair value on a recurring basis are included within the following items on the Company's consolidated balance sheet as of March 24, 2013 and June 24, 2012 (in thousands):

The Company considers as cash and cash equivalents all investments that are highly liquid with an initial maturity of three months or less from the date of purchase.

The fair value of investments, derivatives, and other assets and liabilities are disclosed in Note 2, Note 3, and Note 9, respectively.

During the nine months ended March 24, 2013 and March 25, 2012, for each class of assets and liabilities, there were no transfers between those valued using quoted prices in active markets for identical assets (Level 1), those valued using significant other observable inputs (Level 2), and those valued using significant unobservable inputs (Level 3).  The Company determines at the end of the reporting period whether a given financial asset or liability is valued using Level 1, 2, or 3 inputs.

As of March 24, 2013, the Company's investments recorded at fair value using Level 2 inputs included corporate debt securities and U.S. government agency obligations.  The above assets and liabilities recorded at fair value using Level 2 inputs were valued primarily using an independent valuation firm based on the market approach using various inputs such as trade data, broker/dealer quotes, observable market prices for similar securities and other available data.  The Company also records its foreign currency forward contracts at fair value using Level 2 inputs based on readily observable market parameters for all substantial terms of derivatives.

When at least one significant valuation model assumption or input used to measure the fair value of financial assets or liabilities is unobservable in the market, they are deemed to be measured using Level 3 inputs.  These Level 3 inputs may include pricing models, discounted cash flow methodologies or similar techniques where at least one significant model assumption or input is unobservable.  The Company uses Level 3 inputs to value financial assets that include a non-transferable put option on a strategic investment (the "Put Option") and a liability for an acquisition-related contingent consideration arrangement.  Level 3 inputs were also used to value investment securities that included a certain asset-backed security for which there was decreased observability of market pricing for these investments.

The Company accounts for the Put Option as a derivative instrument not designated as an accounting hedge.  The fair value was determined using the Black-Scholes option pricing model.  The model uses inputs such as exercise price, fair market value of the underlying common stock, expected life (years), expected volatility, risk-free rate equivalent, and dividend yield.  The expected life is the remaining life of the Put Option.  Expected volatility is based on historical volatility of the underlying common stock.  As of March 24, 2013, the Company determined that significant changes in the above assumptions would not materially affect the fair value of the Put Option.  Additionally, the model materially relies on the assumption the issuer of the Put Option will uphold its financial obligation up to its common equity value should the Company exercise the Company's right to put the associated number of common shares back to the issuer at a fixed price in local currency.

For the three and nine months ended March 24, 2013, the Company measured at fair value, on a non-recurring basis, the carrying values of certain equipment in its research and development group, its Newport, Wales, and Mexico manufacturing facilities, and a subcontractor facility located in southeast Asia, due to the non-use of that equipment.  During the three months ended March 24, 2013, the Company determined that the carrying values of certain assets located at the subcontractor facility of $0.3 million exceeded their estimated fair values of zero.  The fair values were determined using the market approach, which considered the estimated fair value of the equipment using significant unobservable inputs (Level 3) obtained from third party equipment brokerage firms.  In addition to the above, during the six months ended December 23, 2012, the Company determined that the carrying values of certain assets in its research and development group, and manufacturing facilities located in Newport, Wales, and Mexico of $8.7 million exceeded their estimated fair values of $4.0 million.  The fair values were determined using the market approach, which considered the estimated fair value of the equipment using significant unobservable inputs (Level 3) obtained from third party equipment brokerage firms.  Consequently, during the three and nine months ended March 24, 2013, the Company recorded impairment charges of $0.3 million and $5.0 million, respectively, which represents the excess of the carrying values of the assets over the fair values, less the estimated cost to sell.  The Company had no significant measurements of assets or liabilities at fair value on a non-recurring basis during the three months and nine months ended March 25, 2012.

Adoption of Recent Accounting Standards

In June 2011, the FASB issued ASC update No. 2011-05, "Comprehensive Income (Topic 220), Presentation of Comprehensive Income" ("ASC 2011-05").  The FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity, among other amendments in this update.  The amendments require that all non-owner changes in stockholder's equity be presented in a single continuous statement of comprehensive income or in two separate but consecutive statements.  In both alternatives, a company is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income.  A company is also required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of comprehensive income are presented.  The adoption of this update did not have a material impact on the Company's financial statements, and the statement of comprehensive income was presented as a separate consecutive statement following the unaudited condensed consolidated statements of operations (See Part I, Item 1, Financial Statements- "Unaudited Condensed Consolidated Statements of Comprehensive Income").

Recent Accounting Standards

In July 2012, the FASB issued ASC update No. 2012-02, "Intangibles-Goodwill and Other (Topic 350), Testing Indefinite-Lived Intangible Assets for Impairment" ("ASC 2012-02").  Under the amendments in this update, a company has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Topic 350.  The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent.  If after assessing the qualitative factors, a company determines it does not meet the more-likely-than-not threshold, a company is required to perform the quantitative impairment test by calculating the fair value of an indefinite-lived intangible asset and comparing the fair value with the carrying amount of the asset.  The amendments in this update are effective for annual and interim impairment test performed for fiscal years beginning after September 15, 2012 (early adoption permitted).  The Company does not believe that adoption of this update will have a material impact on its financial statements.

In February 2013, the FASB issued ASC update No. 2013-02, "Comprehensive Income (Topic 220), Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" (ASC 2013-02).  The objectives of this update require companies to provide information about the amounts reclassified out of accumulated other comprehensive income by component.  In addition, a company is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. The amendments in this update are effective for fiscal years and interim periods within those years beginning after December 15, 2012.  The Company does not believe that adoption of this update will have a material impact on its financial statements.

The Company manages its total portfolio to encompass a diversified pool of investment‑grade securities. The investment policy is to manage its total cash and investments balances to preserve principal and maintain liquidity while achieving moderate returns on the investment portfolio.

In addition, the Company has a note receivable from a privately held company which was carried at cost of $0.4 million in other assets.  This investment was carried at cost as the Company determined that it was nonmarketable since the issuer is a start-up company whose securities are not publicly traded, and as a result, it was not practicable to estimate the fair value of the investment.  During the three months ended March 24, 2013, the privately held company in which the Company has an equity investment experienced a negative change in financial condition.  The Company then evaluated that the investment was permanently impaired and recorded an impairment charge of $0.4 million during the three months ended March 24, 2013.

The Company also holds as strategic investments the common stock of three publicly traded foreign companies.  The common stock of the three companies are shown as "Equity securities" in the tables above and are included in other assets on the consolidated balance sheets.  The common shares of the publicly traded companies are traded on either the Tokyo Stock Exchange or the Taiwan Stock Exchange.  The Company holds an option on one of the strategic investments to put the associated number of common shares back to the issuer at a fixed price in local currency (which is described as the "Put Option" in Note 1).  The Put Option became effective September 1, 2009 and is reported at fair value.  As of March 24, 2013, the fair value of the Put Option was $2.9 million, with changes in fair value recorded in other expense (income), net (See Note 3, "Derivative Financial Instruments").  Dividend income from these investments was $0.1 million and $0.2 million for the three and nine months ended March 24, 2013, respectively, and $0.1 million for the nine months ended March 25, 2012.  The Company received no dividend income from these equity investments during the three months ended  March 25, 2012.

The Company evaluates securities for other-than-temporary impairment on a quarterly basis. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include the length of time and extent to which the market value has been less than cost; the financial condition and near-term prospects of the issuer of the securities; and the intent and ability of the Company to retain the security in order to allow for an anticipated recovery in fair value. If, based upon the analysis, it is determined that the impairment is other-than-temporary, the security is written down to fair value, and a loss is recognized through earnings.

The following table provides the Company's other-than-temporary impairments for equity and mortgage-backed securities for the three and nine months ended March 24, 2013 and March 25, 2012 (in thousands):

	Three Months Ended				Nine Months Ended

As of March 24, 2013, the Company evaluated whether equity securities with gross unrealized losses of $0.2 million was other-than-temporarily impaired.  The Company determined there was no indication of other-than-temporary impairment with regards to gross unrealized losses.  The determination was based on the fact the Company has evaluated the near-term prospects of the equity investments in relation to the severity and duration of the impairment, and based on that evaluation, has the ability and intent to hold these investments until a recovery of fair value.

The amortized cost and estimated fair value of investments at March 24, 2013, by contractual maturity, are as follows (in thousands):

	Amortized Cost		Estimated Market Value
Due in 1 year or less	$	15,053	$	15,058

The Company may decide to dispose of securities prior to the contractual maturity date indicated in the table above.

During the nine months ended March 24, 2013, available-for-sale securities were sold for total proceeds of $52.1 million, and for the three and nine months ended March 25, 2012 were sold for total proceeds of $12.2 million and $27.1 million, respectively.  During the three months ended March 24, 2013, there were no sales of available-for-sale securities, and as a result, the Company did not recognize any gross realized gains (losses).  Gross realized gains (losses) for the nine months ended March 24, 2013 and March 25, 2012 were de minimis.

3. Derivative Financial Instruments

The Company is exposed to financial market risks, including fluctuations in interest rates, foreign currency exchange rates and market value risk related to its investments.  The Company uses derivative financial instruments primarily to mitigate foreign exchange rate risks, but also as part of its strategic investment program.  In the normal course of business, the Company also faces risks that are either non-financial or non-quantifiable.  Such risks principally include country risk, credit risk and legal risk, and are not discussed or quantified in the following analyses.  As of March 24, 2013, the Company's only derivatives were currency forward contracts which were not designated as accounting hedges, the Put Option (See Note 2, "Investments"), and a call option on the equity of a private domestic company.  The private domestic company is a development stage entity, and as such, the Company is unable to determine the fair value of the call option at this time.

Interest Rates

The Company is subject to interest rate risk through its investments.  The objectives of the Company's investments in debt securities are to preserve principal and maintain liquidity while maximizing returns.  To achieve these objectives, the returns on the Company's investments in short-term debt generally will be compared to yields on money market instruments such as U.S. Commercial Paper programs, LIBOR, or U.S. Treasury Bills.  Investments in long-term debt securities will be generally compared to yields on comparable maturity of U.S. Treasury obligations, investment grade corporate instruments with an equivalent credit rating or an aggregate benchmark index.

The Company had no outstanding interest rate derivatives as of March 24, 2013.

3. Derivative Financial Instruments (Continued)

Foreign Currency Exchange Rates

The Company generally hedges the risks of foreign currency-denominated repetitive working capital positions with offsetting foreign currency denominated exchange transactions, using currency forward contracts or spot transactions.  Transaction gains and losses on these foreign currency-denominated working capital positions are generally offset by corresponding gains and losses on the related hedging instruments, usually resulting in reduced net exposure.  The Company does not hedge its revenues and expenses against changes in foreign currency exchange rates, as it does notperceive the net risk of changes to translated revenues and expenses from changes in exchange rates as significant enough at this time to justify hedging.

A significant amount of the Company's revenues, expense, and capital purchasing transactions are conducted on a global basis in several foreign currencies.  At various times, the Company has currency exposure related to the British Pound Sterling, the Euro, and the Japanese Yen.  For example, in the United Kingdom, the Company has a sales office and a semiconductor wafer fabrication facility with revenues in U.S. Dollars and Euros, and expenses in British Pounds Sterling and U.S. Dollars.  To protect against exposure to currency exchange rate fluctuations on non-functional currency payables and receivables, the Company has established a balance sheet transaction risk hedging program.  This risk hedging program generally uses spot and currency forward contracts.  These contracts are not designated as hedging instruments for accounting purposes.  Through this hedging program, the Company seeks to reduce, but does not always entirely eliminate, the impact of currency exchange rate movements.

For its balance sheet transaction risk hedging program, the Company had approximately $43.8 million in notional amounts of currency forward contracts not designated as accounting hedges at March 24, 2013.  The net realized and unrealized foreign‑currency gains (losses) related to forward contracts not designated as accounting hedges recognized in earnings, as a component of other expense (income), net, were $2.1 million and $(0.0) million for the three and nine months ended March 24, 2013, respectively, and $(0.9) million and $(5.7) million for the three and nine months ended March 25, 2012, respectively.

At March 24, 2013 and June 24, 2012, the fair value carrying amount of the Company's derivatives not designated as hedging instruments were as follows (in thousands):

Goodwill

The Company evaluates the carrying value of goodwill and other intangible assets annually during the fourth quarter of each fiscal year and more frequently if it believes indicators of impairment exist.  In evaluating goodwill, a two-step goodwill impairment test is applied to each reporting unit.  The Company identifies reporting units and determines the carrying value of each reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets, to those reporting units.  In the first step of the impairment test, the Company estimates the fair value of the reporting unit.  If the fair value of the reporting unit is less than the carrying value of the reporting unit, the Company performs the second step which compares the implied fair value of the reporting unit with the carrying amount of the reporting unit and writes down the carrying amount of the goodwill to the implied fair value.

The carrying amount of goodwill by reportable segment as of March 24, 2013 and June 24, 2012 was as follows (in thousands):

Business Segments:	March 24, 2013		June 24, 2012

7. Revolving Credit Facility and Bank Letters of Credit

Revolving Credit Facility

On October 25, 2012 (the "Closing Date"), the Company entered into a Credit Agreement (the "Credit Agreement"), as borrower, with Wells Fargo Bank, National Association, as Administrative Agent ("Agent"), and certain lenders (the "Lenders"), pursuant to which it established a new senior unsecured revolving credit facility (the "Facility") in an aggregate principal amount of $100 million with sublimits for swingline loans (of $25 million) and the issuance of letters of credit (of $10 million).  The Credit Facility matures on October 25, 2016.  The proceeds of the Credit Facility may be used by the Company to finance certain capital expenditures and acquisitions permitted thereunder, to provide for the working capital and general corporate needs as well as to pay fees, commissions and expenses associated with the Credit Facility.

The terms of the Credit Agreement require the Company to comply with certain financial tests, and include various affirmative and negative covenants, and customary representations and warranties, conditions and events of default.  Additionally, the Credit Facility is subject to a commitment fee on the unused portion at an initial rate equal to 0.25 percent per annum.  As of March 24, 2013, the Company was in compliance with the financial tests and covenants, and there were no amounts outstanding under the Credit Facility.

Bank Letters of Credit

At March 24, 2013, the Company had $0.7 million of outstanding letters of credit.  These letters of credit are secured by cash collateral provided by the Company equal to their face amount.

Warranty

The Company records warranty liabilities at the time of sale for the estimated costs that may be incurred under the terms of its warranty agreements.  The specific warranty terms and conditions vary depending upon the product sold and the country in which the Company does business.  In general, for standard products, the Company will replace defective parts not meeting the Company's published specifications at no cost to the customers.  Factors that affect the liability include historical and anticipated failure rates of products sold, and cost per claim to satisfy the warranty obligation.  If actual results differ from the estimates, the Company revises its estimated warranty liability to reflect such changes.

11. Asset Impairment, Restructuring and Other Charges

Asset impairment, restructuring and other charges reflect the impact of certain cost reduction programs and initiatives implemented by the Company.  These programs and initiatives include the closing of facilities, the termination of employees and other related activities.  Asset impairment, restructuring and other charges include program-specific exit costs, severance benefits pursuant to an ongoing benefit arrangement, and special termination benefits.  Severance costs unrelated to the Company's restructuring initiatives are recorded as an element of cost of sales, research and development ("R&D") or selling, general and administrative expense ("SG&A"), depending upon the classification and function of the employee terminated.  Restructuring costs are expensed during the period in which all requirements of recognition are met.

Asset write-downs are principally related to facilities and equipment that will not be used subsequent to the completion of exit or downsizing activities being implemented, and cannot be sold for amounts in excess of carrying value.  In determining the asset groups for the purpose of calculating write-downs, the Company groups assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities.  In determining whether an asset is impaired, the Company evaluates estimated undiscounted future cash flows and other factors such as changes in strategy and technology. An impairment loss exists if the estimated undiscounted future cash flows are less than the carrying amount of the asset group. The Company then determines the fair value of the asset group by discounting the estimated future cash flows, consistent with the cash flows of a market participant, at a discount rate that is used when analyzing potential acquisitions. The Company then compares the fair value of the asset group with the carrying amount of the asset group and writes down the carrying amount of the asset group to its fair value.

During the first quarter of fiscal year 2013, the Company announced a restructuring plan to modify its manufacturing strategy and lower its operating expenses in order to align its cost structure with business conditions.  As part of the plan, the Company expects to incur costs recorded in asset impairment, restructuring and other charges related primarily to the following:

•Fiscal Year 2013 El Segundo Fabrication Facility Closure Initiative

•Fiscal Year 2013 Newport Fabrication Facility Resizing Initiative

•Fiscal Year 2013 Other Cost Reduction Activities Initiative

Fiscal Year 2013 Initiatives

Fiscal Year 2013 El Segundo Fabrication Facility Closure Initiative

During the first quarter of fiscal year 2013, the Company adopted a restructuring plan to close its El Segundo wafer fabrication facility by the third quarter of fiscal year 2013.  In connection with the plan, the Company estimates it will incur total pre-tax costs of $7.3 million.  These costs consist of $5.9 million of severance and workforce reduction costs, $1.2 million of relocation and re-qualification costs, and $0.2 million of asset impairment costs. In addition to the restructuring charges above, during the three and nine months ended March 24, 2013, the Company recorded $0.2 million and $1.4 million of other charges related to the restructuring initiative in cost of sales.  These other charges, which were for accelerated depreciation and inventory write-downs, are not classifiable as restructuring costs, and affected the ESP reporting segment.

During the three and nine months ended March 24, 2013, cash payments for this initiative were $2.9 million and $5.3 million, respectively, and are estimated to be approximately $0.9 million and $1.0 million for the remainder of fiscal year 2013 and thereafter, respectively.

In addition, the Company estimates it will make cash expenditures of $2.5 million for the decontamination and restoration of this fabrication facility.  These costs were previously considered as part of the asset impairment of the El Segundo Fabrication Facility recorded in the fourth quarter of fiscal year 2012, and are not anticipated to result in additional restructuring charges.

Fiscal Year 2013 Newport, Wales Fabrication Facility Resizing Initiative

During the first quarter of fiscal year 2013, the Company adopted a restructuring plan to resize its wafer fabrication facility in Newport, Wales in several phases by the middle of calendar year 2015.  In connection with the plan, the Company estimates it will incur total pre-tax costs of approximately $13.6 million.  These costs consist of approximately $0.7 million of asset impairment costs, $2.4 million of severance and workforce reduction costs, $4.4 million of decommissioning costs, and $6.1 million of relocation and re-qualification costs.

During the three and nine months ended March 24, 2013, cash payments for this initiative were $0.5 million and $1.7 million, respectively, and are estimated to be approximately $1.5 million and $9.7 million for the remainder of fiscal year 2013 and thereafter, respectively.

Fiscal Year 2013 Other Cost Reduction Activities Initiative

During the first nine months of fiscal year 2013, the Company undertook certain actions to reduce (i) capacity at manufacturing facilities in Mexico, California, and Arizona, as well as (ii) administrative and research and development costs around the world.  As part of the plan, the Company has incurred approximately $5.0 million of severance and workforce reduction costs so far in fiscal year 2013.  The severance and workforce reduction costs recorded during the three months ended March 24, 2013 included $0.2 million for research and development functions.  During the nine months ended March 24, 2013, severance and workforce reduction costs included $2.6 million related to manufacturing functions, and $1.1 million for general and administrative functions, and $1.3 million for research and development functions.

As part of those ongoing efforts, during the nine months ended March 24, 2013, the Company incurred $1.1 million of asset impairment costs for the planned disposition of certain manufacturing equipment related to its manufacturing facility in Mexico, and may incur additional amounts in the future.

The Company has identified a few additional cost reduction actions to be implemented during the three months ending June 30, 2013, at which point this initiative is expected to be completed. 

During the three and nine months ended March 24, 2013, cash payments for this initiative were $1.1 million and $4.9 million, respectively, and are estimated to be approximately $0.2 million for the remainder of fiscal year 2013.

12. Segment Information (Continued)

The Company does not allocate assets, sales and marketing, information systems, finance and administrative costs and asset impairment, restructuring and other charges to the operating segments, as these are not meaningful statistics to the CEO in making resource allocation decisions or in evaluating performance of the operating segments.  Because operating segments are generally defined by the products they design and sell, they do not make sales to each other.

The Company does not directly allocate assets to its operating segments, nor does the CEO evaluate operating segments using discrete asset information.  However, depreciation and amortization related to the manufacturing of goods is included in gross profit for the segments as part of manufacturing overhead.  Due to the Company's methodology for cost build up at the product level, it is impractical to determine the amount of depreciation and amortization included in each segment's gross profit.

The Company's "Customer Segments" includes PMD, ESP, AP, EP and HiRel reporting segments.

For the three and nine months ended March 24, 2013 and March 25, 2012, revenues and gross margin by reportable segments were as follows (in thousands, except percentages):

13. Income Taxes

The Company recorded a tax expense of $1.6 million or 8.1 percent against a loss of $19.6 million for the three months ended March 24, 2013.   The expense was mainly due to $1.9 million in foreign income taxes, $0.5 million in withholding taxes, and $0.2 million in domestic tax expense.  This expense was partially offset by a reduction in foreign uncertain tax positions, arising from lapses in statutes of limitation of approximately $0.6 million, and the utilization of a $0.4 million state tax credit.

The Company recorded a tax expense of $6.1 million or 8.0 percent against a loss of $76.6 million for the nine months ended March 24, 2013.  This was mainly due to a decrease in the United Kingdom ("U.K.") statutory tax rates, which reduced the value of the Company's net deferred tax assets in the U.K. by $3.2 million, expenses related to foreign income taxes of $4.6 million, foreign withholding taxes of $2.0 million, and domestic tax expense of $1.4 million.  The expense was partially offset by the benefit of $4.7 million arising from reduction in uncertain tax positions during the second and third quarters, and the utilization of a $0.4 million state tax credit.

The Company recorded a tax benefit of $4.5 million or 64.5 percent against a loss of $7.0 million for the three months ended March 25, 2012, and an expense of $2.8 million or 17.8 percent against income of $15.9 million for the nine months ended March 25, 2012.  For the three months ended March 25, 2012, the Company recorded a tax benefit of $4.5 million due to a valuation allowance release of $7.8 million related to deferred tax assets in the U.K., $3.1 million related to deferred tax assets in the U.S., a tax benefit of $1.6 million from an unrealized gain which was partially offset by $3.5 million in withholding taxes, $2.3 million in foreign taxes, $1.8 million of deferred charges, and $0.6 million increase in uncertain tax positions.  For the  nine months ended March 25, 2012, the Company recorded a tax expense of $2.8 million due to foreign taxes of $7.3 million, withholding taxes of $3.5 million, deferred charges of $1.8 million, an increase in uncertain tax positions of $1.4 million, tax rate changes that decreased the Company's deferred tax assets by $0.6 million, and $0.6 million in domestic tax expense which was partially offset by the release of $10.9 million of valuation allowances and a $1.6 million benefit from an unrealized gain.

The Company evaluates its net deferred income tax assets quarterly to determine if valuation allowances are required.  Based on the consideration of all available evidence using a "more-likely-than-not" standard, the Company determined that the valuation allowance established against its federal and California deferred tax assets in the U.S. should remain in place through fiscal year 2013.  These valuation allowances relate to beginning of fiscal year 2013 balances of reserves that were established during fiscal year 2009.  

The Company operates in multiple foreign jurisdictions with lower statutory tax rates, and its operations in Singapore generally have the most significant impact on the Company's effective tax rate. During fiscal year 2011, the Company was granted certain incentives by the Singapore Economic Development Board.  As a result, the Company operates under a tax holiday in Singapore, effective from December 27, 2010 through December 26, 2020.  The tax holiday is conditioned upon the Company meeting certain employment and investment thresholds which have been met to date.  The Company has not realized a benefit for this reporting period.

During the three months ended March 24, 2013, the reserve for uncertain tax positions increased by $1.6 million to $45.1 million.  This increase resulted primarily from a $3.0 million increase to reserves associated with domestic uncertain tax positions.  The increase was offset by an expiration of statute of limitations of $0.6 million and $0.8 million from changes in currency exchange rates related to prior year uncertain tax positions in certain foreign jurisdictions.  For fiscal year 2013, the benefits associated with uncertain tax positions would result in a benefit to income taxes on the consolidated statement of operations of $13.2 million, and if recognized, would reduce the Company's future effective tax rate.  The reserve is expected to decrease by $7.5 million during the next 12 months primarily due to a lapse in the statute of limitations in certain foreign jurisdictions.

As of March 24, 2013, the Company's accrual of interest and penalties related to uncertain tax positions was $4.0 million.  For the three months ended March 24, 2013, penalties and interest included in the reserves decreased by $0.3 million.

While it is often difficult to predict the final outcome or the timing of the resolution of any particular uncertain tax position, the Company believes its reserve for income taxes represents the most probable outcome. The Company adjusts this reserve, including the portion related to interest, in light of changing facts and circumstances.

As of June 24, 2012, U.S. income taxes have not been provided on approximately $95.3 million of undistributed earnings of foreign subsidiaries since those earnings are considered to be invested indefinitely. Determination of the amount of unrecognized deferred tax liabilities for temporary differences related to investments in these non-U.S. subsidiaries that are essentially permanent in duration is not practicable.

Pursuant to Sections 382 and 383 of the U.S. Internal Revenue Code, the utilization of net operating losses ("NOLs") and other tax attributes may be subject to substantial limitations if certain ownership changes occur during a three-year testing period (as defined). The Company does not believe an ownership change has occurred that would limit the Company's utilization of any NOL, credit carry forward or other tax attributes.

The Company calculates earnings per share using the two-class method.  The two-class method requires allocating the Company's net income to both common shares and participating securities.  The Company's participating securities include the unvested, outstanding RSUs to the extent the RSUs provide for the right to receive dividend equivalents.

The following table provides a reconciliation of the numerator and denominator of the basic and diluted per-share computations for the three and nine months ended March 24, 2013 and March 25, 2012 (in thousands, except per share amounts):

	Three Months Ended						Nine Months Ended
	March 24, 2013			March 25, 2012			March 24, 2013			March 25, 2012
Net income (loss)	$	(21,245	)	$	(2,490	)	$	(82,742	)	$	13,136

15. Environmental Matters

Federal, state, local and foreign laws and regulations impose various restrictions and controls on the storage, use and discharge of certain materials, chemicals and gases used in semiconductor manufacturing processes, and on the operation of the Company's facilities and equipment. The Company believes it uses reasonable efforts to maintain a system of compliance and controls for these laws and regulations. Despite its efforts and controls, from time to time, issues may arise with respect to these matters. Additionally, under some of these laws and regulations, the Company could be held financially responsible for remedial measures if properties are contaminated or if waste is sent to a landfill or recycling facility that becomes contaminated. Also, the Company may be subject to common law claims if released substances damage or harm third parties. The Company cannot make assurances that changes in environmental laws and regulations will not require additional investments in capital equipment and the implementation of additional compliance programs in the future, which could have a material adverse effect on the Company's results of operations, financial position or cash flows, as could any failure by or violation of the Company to comply with any prior, current or future environmental laws and regulations.

In February 2012, the Company notified the California Department of Toxic Substances Control ("DTSC") and local districts that the Company's Temecula California manufacturing facility previously shipped wastes for disposal offsite as non-hazardous wastes which may have contained fluoride levels that are considered to constitute hazardous waste under California regulations.  The Company has taken steps to ensure compliance with the applicable waste disposal regulations in this regard.  The Company has received a notice of minor administrative violation from one of the local districts requiring updated permit documentation without the assessment of any penalty.  The Company has not as yet been contacted by all applicable regulatory authorities, including the DTSC,  in respect of this matter and it is too early to assess what, if any, penalties or other actions may be taken in the future in respect of the matter.

In December 2010, the owner by foreclosure of a property in El Segundo, California formerly owned and leased by the Company notified the Company of its claim that the Company is a potentially responsible party for the remediation of hazardous materials allegedly discovered by that owner at the property.  The Company had also been contacted by the California Department of Toxic Substances Control in connection with that 2010 notice.  Separately, in July 2012, the Company received notice from a subsequent owner of that property seeking reimbursement of investigation costs and increased construction costs allegedly resulting from the presence of hazardous materials at the property.  The Company intends to vigorously defend against all of the claims asserted by the various parties in respect of the property.

During negotiations for the Company's April 2007 divestiture of the Company's Power Control Systems business to Vishay Intertechnology, Inc., certain chemical compounds were discovered in the groundwater underneath one of the Company's former manufacturing plants in Italy, and the Company advised appropriate governmental authorities at about the time of such divestiture.  In August 2010, the Company received a letter from the relevant local authority requiring a confirmation of intention to proceed with preparation of a plan of characterization in relation to the site in question.  The Company has restated to local authorities its prior position from the period following such divestiture that it had not committed to take further action with respect to the site. In October 2012, local authorities contacted the current site owner suggesting that additional groundwater testing should take place and testing was conducted prior to the close of calendar year 2012.  The Company has not been assessed any penalties with respect to the site, and it is too early to assess whether any such penalties will be assessed or other regulatory actions may be taken in the future.

15. Environmental Matters (Continued)

In November 2007, the Company was named as one of approximately 100 defendants in Angeles Chemical Company, Inc. et al. v. Omega Chemical PRP Group, LLC et al., No. EDCV07-1471 (TJH) (JWJx) (C.D. Cal.) (the "Angeles Case"). Angeles Chemical Company, Inc. and related entities ("Plaintiffs") own or operate a facility (the "Angeles Facility") which is located approximately one and a half miles down gradient of the Omega Chemical Superfund Site (the "Omega Site") in Whittier, California. Numerous parties, including the Company, allegedly disposed of wastes at the Omega Site. Plaintiffs claim that contaminants from the Omega Site migrated in groundwater from the Omega Site to the Angeles Facility, thereby causing damage to the Angeles Facility. In addition, they claim that the EPA considers them to be responsible for the groundwater plume near the Angeles Facility, which Plaintiffs contend was caused by disposal activities at the Omega Site. Plaintiffs filed claims based on the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), nuisance and trespass, and also seek declaratory relief. Plaintiffs seek to require the defendants to investigate and clean-up the contamination and to recover damages. The case has been stayed by the court pending the Environmental Protection Agency's completion of its remedial investigation. The Company previously entered into a settlement with other parties associated with the Omega Site pursuant to which the Company paid those entities money in exchange for an agreement to defend and indemnify the Company with regard to certain environmental claims (the "Omega Indemnification"). In that agreement, it was estimated that the Company's volumetric share of wastes sent to the Omega Site was in the range of 0.08 percent. The Company believes that much, if not all, of the risks associated with the Angeles Case should be covered by the Omega Indemnification. In addition, the Company has tendered the complaint to several of its insurance carriers, one of which has agreed to defend under a reservation of rights. Therefore, the Company does not expect its out-of-pocket defense costs to be significant. In addition, in light of the Omega Indemnification, the potential for insurance coverage and the fact that its volumetric share of Omega Site wastes was less than 0.1 percent, the Company does not believe that an adverse judgment against the Company would be material.

IR and Rachelle Laboratories, Inc. ("Rachelle"), a subsidiary of the Company that discontinued operations in 1986, were each named a potentially responsible party ("PRP") in connection with the investigation by the United States Environmental Protection Agency ("EPA") of the disposal of allegedly hazardous substances at a major superfund site in Monterey Park, California ("OII Site"). Certain PRPs who settled certain claims with the EPA under consent decrees filed suit in Federal Court in May 1992 against a number of other PRPs, including IR, for cost recovery and contribution under the provisions of the CERCLA. The Company has settled all outstanding claims that have arisen against IR relating to the OII Site. No claims against Rachelle have been settled. The Company has taken the position that none of the wastes generated by Rachelle were hazardous.

Counsel for Rachelle received a letter dated August 2001 from the U.S. Department of Justice, directed to all or substantially all PRPs for the OII Site, offering to settle claims against such parties for all work performed through and including the final remedy for the OII Site. The offer required a payment from Rachelle in the amount of approximately $9.3 million in order to take advantage of the settlement. Rachelle did not accept the offer.

It remains the position of Rachelle that its wastes were not hazardous.  In addition, Rachelle operated as an independent corporation and the Company did not believe that a complaining party would be successful in reaching the assets of IR even if it could prevail on a claim against Rachelle.  Because Rachelle has not been sued, none of the Company's insurers has accepted liability, although at least one of the Company's insurers previously reimbursed IR for defense costs for the lawsuit filed against IR.

The Company received a letter in June 2001 from a law firm representing UDT Sensors, Inc. ("UDT") relating to environmental contamination (chlorinated solvents such as trichlorethene) purportedly found in UDT's properties in Hawthorne, California.  The letter alleges that the Company operated a manufacturing business at that location in the 1970's and/or 1980's and that it may have liability in connection with the claimed contamination.  The Company has made no accrual for any potential losses since there has been no assertion of specific facts on which to form the basis for determination of liability.

16. Litigation

EPC/Lidow Litigation.

In September 2008, the Company filed suit in the U.S. District Court for the Central District of California against Efficient Power Conversion Corp. ("EPC"), certain of EPC's employees and other defendants (including Alex Lidow, a former chief executive officer and director of the Company, and now a principal of EPC) alleging improper and  unauthorized use and/or misappropriation of certain Company confidential information, trade secrets and technology related to the Company's Gallium Nitride development program.  In 2009, the Company refiled the suit in the Los Angeles Superior Court, Case No. BC409749.  Alex Lidow and EPC asserted claims against the Company arising out of Lidow's employment with and separation from the Company, for violations of the California Labor Code and California Business and Professions Code, and alleging the Company unfairly competed and interfered with EPC. Those claims have been consolidated with and in the Company's action.

In January 2012, the trial court granted summary adjudication in favor of the Company on the wrongful termination cause of action filed by Lidow; however, on June 23, 2012, the Court of Appeal filed a writ of mandate directing that the trial court's order be vacated and that a new order denying summary adjudication be entered.  The Company subsequently filed a petition for review in the California Supreme Court, which was denied.

Discovery is ongoing, and the Company intends to vigorously pursue all rights and defenses available to it in these matters.

Angeles v. Omega.  See Note 15, "Environmental Matters."

In addition to the above, the Company is involved in certain legal matters that arise in the ordinary course of business. The Company intends to pursue its rights and defend against any claims brought by third parties vigorously. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, the Company's business, financial condition, results of operations or cash flows could be materially and adversely affected.

17. Commitments and Contingencies

In connection with the divestiture of the Company's Power Control Systems business in fiscal year 2007, the Company recorded a provision of $18.6 million for certain tax obligations with respect to divested entities. The balance of the divested entities tax obligations have decreased over time due to settlement of tax audits, lapsing of applicable statutes of limitations, and the decrease in foreign currency translation on the underlying obligation.  As of March 24, 2013, the balance of the divested entities tax obligations was $0.9 million.

18. Stock Repurchase Program

The Company's stock repurchase program authorizes it to repurchase up to $150.0 million of common stock. Stock repurchases under this program may be made in the open market or through privately negotiated transactions. The timing and actual number of shares repurchased depend on market conditions and other factors. The stock repurchase program may be suspended at any time without prior notice. The Company has used and plans to continue to use existing cash to fund the repurchases. All of the shares repurchased by the Company through the program were purchased in open market transactions. For the nine months ended March 24, 2013, the Company repurchased approximately 0.3 million shares for approximately $5.2 million, and to date the Company has purchased approximately 6.2 million shares for approximately $113.2 million under the program.  During the three months ended March 24, 2013, the Company did not repurchase any shares under the stock repurchase program.  As of March 24, 2013, the Company had not cancelled the repurchased shares of common stock, and as such, they are reflected as treasury stock in the March 24, 2013 and June 24, 2012 consolidated condensed balance sheets.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") should be read in conjunction with our audited historical consolidated financial statements which are included in our Form 10-K, filed with the SEC on August 23, 2012 ("2012 Annual Report").  Except for historic information contained herein, the matters addressed in this MD&A constitute "forward‑looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended ("Securities Act"), and Section 21E of the Exchange Act, as amended. Forward‑looking statements may be identified by the use of terms such as "anticipate," "believe," "expect," "intend," "project," "will," and similar expressions. Such forward‑looking statements are subject to a variety of risks and uncertainties, including those discussed under the heading "Statement of Caution Under the Private Securities Litigation Reform Act of 1995," in Part II, Item 1A, "Risk Factors" and elsewhere in this Quarterly Report on Form 10-Q, that could cause actual results to differ materially from those anticipated by us.  We undertake no obligation to update these forward‑looking statements to reflect events or circumstances after the date of this Quarterly Report or to reflect actual outcomes.

Introduction

The following discussion and analysis provides information we believe is relevant to an assessment and understanding of our consolidated results of operations and financial condition.  This discussion should be read in conjunction with our condensed consolidated financial statements and accompanying notes for the three and nine months ended March 24, 2013.  The discussion includes:

· Overview

· Results of Operations

· Liquidity and Capital Resources

· Critical Accounting Policies

Overview

Our revenues were $224.3 million and $248.1 million for the three months ended March 24, 2013 and March 25, 2012, respectively, and $700.6 million and $780.9 million for the nine months ended March 24, 2013 and March 25, 2012, respectively. Our revenues increased $0.4 million or 0.2 percent compared to the three months ended December 23, 2012.  We currently expect revenues for the fourth quarter of fiscal year 2013 to be between $255 million and $265 million.  The fourth quarter of fiscal year 2013 is a 14-week quarter, though, rather than the usual 13 weeks.  If pro-rated to a typical 13-week quarter, this range would translate to $237 to $246 million in comparison to the $224.3 million in the third quarter; however, since business is not strictly linear in any given quarter, proration is only an approximate comparison.

Our gross margin percentage declined on a year-over-year basis by 5.5 percentage points to 24.3 percent for the three months ended March 24, 2013 compared to the three months ended March 25, 2012 and by 9.8 percentage points to 24.8 percent for the nine months ended March 24, 2013 compared to the nine months ended March 25, 2012. The decrease in gross margin percentage for both the three months and nine months ended March 24, 2013 was mainly a result of a decrease in factory utilization and an unfavorable product mix due to a decline in industrial component sales, which generally have higher gross margins than our consumer and computing component product sales.  We currently expect our gross margin percentage for the fourth quarter of fiscal year 2013 to be between 28 percent and 30 percent.

During the nine months ended March 24, 2013, we continued to implement a number of initiatives to adjust our internal manufacturing footprint and otherwise reduce costs.  We also continued our existing efforts to increase our manufacturing flexibility by qualifying additional technologies and higher value-added products and programs with our contract wafer fabrication and assembly and test suppliers.  We will continue to monitor the demand environment and we may seek to further adjust our operational footprint and take other actions to reflect changes in demand in future periods.

34

In August 2012, we adopted a restructuring plan to modify our manufacturing strategy and lower our operating expenses in order to more closely align our cost structure with current business conditions.  As part of the plan, we closed our El Segundo wafer fabrication facility in March 2013 with an estimated annual cost savings of approximately $10 million.  As an additional part of the plan, the resizing of our Newport, Wales fabrication facility is expected to continue in several phases through the middle of calendar year 2015 with estimated annual cost savings of approximately $16 million following completion.  Further, we have taken other cost reduction actions to reduce our manufacturing footprint, primarily in our Tijuana, Mexico assembly facility and our worldwide manufacturing overhead groups.

Also as part of our restructuring plan, during the nine months ended March 24, 2013, we reduced our selling, general and administrative ("SG&A") costs and research and development ("R&D") costs mainly through headcount reductions.  In the third quarter of fiscal year 2013, when compared to our run rate exiting the three months ended June 24, 2012, we realized annual cost savings of over $40 million attributed to the combination of headcount reductions from the restructuring and other reductions in spending in our SG&A and R&D expenses.  We will continue to identify additional SG&A and R&D cost savings in order to seek to maintain our total of such expenses at approximately $75 million per quarter when our business is operating at higher revenue levels, even as certain costs (such as incentive bonuses and freight costs) scale upward.   In conjunction with our ongoing operational restructuring plans, we incurred approximately $11.4 million of severance and workforce reduction costs, $1.9 million of asset impairment costs, $1.4 million of equipment relocation and re-qualification costs, and $0.1 million of decommissioning costs during the nine months ended March 24, 2013.  Additionally, we anticipate that we will incur restructuring charges during the remainder of fiscal year 2013 of approximately $1.9 million (See Part I, Item 1, Notes to Consolidated Financial Statements-Note 11, "Asset Impairment, Restructuring and Other Charges").

During the three and nine months ended March 24, 2013, our SG&A expenses decreased by $6.6 million and $13.7 million compared to the three and nine months ended March 25, 2012, respectively.  The year-over-year decrease in SG&A expenses was primarily due to a decrease in headcount related expenses, decreased professional services and decreased travel expenses, partly offset by higher litigation expenses and increased stock compensation expense.  Additionally, depreciation increased by $2.8 million for the nine months ended March 24, 2013 due to the implementation of our Enterprise Resource Planning ("ERP") system at the beginning of the second quarter of fiscal year 2012. We expect our SG&A expenses to be about $47million in the fourth quarter of fiscal year 2013.

During the three and nine months ended March 24, 2013, R&D expenses decreased $5.9 million and $5.6 million compared to the three and nine months ended March 25, 2012, respectively.  The year-over-year decrease in R&D was primarily driven by lower headcount related expenses as a result of our restructuring initiatives and lower material costs, which were partly offset by the exhaustion of certain reimbursable grant funding at the end of fiscal year 2012, increased asset impairment expense, and increased stock compensation expense.  We expect our R&D expenses to be about $32 million in the fourth quarter of fiscal year 2013.

Our cash flows from operating activities provided $81.6 million of cash during the first nine months of fiscal year 2013 compared to a use of cash of $17.3 million for prior year comparable period.  Our cash, cash equivalents and investments as of March 24, 2013 totaled $402.1 million (excluding restricted cash of $1.4 million), compared to $384.3 million (excluding restricted cash of $1.5 million) as of June 24, 2012.  The increase in our cash and investments was primarily due to a $63.0 million reduction in inventory and a $33.5 million reduction in accounts receivable, significantly offset by our $76.6 million operating loss during the nine months ended March 24, 2013.

35

Segment Reporting

For the description of our reportable segments, see Note 12, "Segment Information," to our Consolidated Financial Statements set forth in Part I, Item 1.

Four of our five Customer Segments (as identified below), namely, PMD, ESP, AP and EP, generally share the same manufacturing base and sales, marketing, and distribution channels.  While each segment focuses on different target markets and applications, there are common performance elements arising from that shared manufacturing base and sales, marketing, and distribution channels.  As a result, while we manage performance of these segments individually, we also analyze performance of these segments together, separately from our other customer segment, HiRel.  For ease of reference, we refer to these four segments collectively as our "Commercial Segments."  What we refer to as our "Customer Segments" include our PMD, ESP, AP, EP and HiRel reporting segments.

Fiscal Calendar

When operating under a 52/53 week fiscal calendar, it becomes necessary to have a longer fiscal period approximately every 5-6 years.  In fiscal year 2013, our fiscal year will be 53 weeks long and end on Sunday June 30, 2013.  Accordingly, our fourth fiscal quarter will be 14 weeks long, instead of 13 weeks.  As a result, we expect that revenues and most costs (but not all) will be increased in that quarter to approximately 108 percent of what they otherwise would have been for the typical 13-week quarter.

Revenues

Revenues from all our segments, taken as a whole, decreased by $23.8 million, or 9.6 percent, attributed to revenues from our Customer Segments (which excludes the IP segment) decreasing by $23.7 million, or 9.6 percent, for the three months ended March 24, 2013 as compared to three months ended March 25, 2012.  Revenues for our Commercial Segments taken as a whole decreased 9.3 percent from the three months ended March 25, 2012.  Revenues for our HiRel segment decreased 10.5 percent from the three months ended March 25, 2012.

Within our Commercial Segments, revenue from our AP segment increased 8.0 percent for the three months ended March 24, 2013 as compared to the three months ended March 25, 2012.  Revenues for our AP segment increased due to increased demand for new IGBT and MOSFET products.  Revenues for our PMD segment increased 5.6 percent due to increased demand for our universal power supply and industrial products components.  Revenues for our EP segment decreased 36.4 percent due to a decrease in demand for high performance computing and prior generation server components resulting from customer push outs and loss of market share in upcoming server generation components.  Revenues for our ESP segment decreased 24.0 percent due to decreased demand in our industrial and consumer appliance related products resulting from a significant market slowdown in Asia and inventory reductions at our customers.

For the three months ended March 24, 2013, our HiRel segment revenues decreased 10.5 percent compared to the three months ended March 25, 2012.  HiRel experienced a decrease in shipments due to production issues associated with a fabrication transfer.

For the three months ended March 24, 2013, our IP segment revenues decreased $0.1 million, to $0.3 million, compared to the three months ended March 25, 2012.

Our gross margin percentage decreased by 5.5 percentage points to 24.3 percent for the three months ended March 24, 2013 compared to the three months ended March 25, 2012.  This decrease in our gross margin percentage was the result of a decrease of 3.2 percentage points in gross margin for our Commercial Segments taken as a whole, and a decrease of 14.9 percentage points in gross margin for our HiRel segment.  The decrease in gross margin for our Commercial Segments taken as a group was primarily due to unfavorable product mix from all of segments except our EP segment.  Our ESP segment's gross margin decline was due primarily to increased costs associated with lower factory utilization and unfavorable product mix.  ESP has been particularly severely impacted by the underutilization of several of our manufacturing plants, including our recently closed fabrication facility in El Segundo, California.  As a result, we expect ESP gross margins to improve as our revenue grows and the effects of underutilization diminish.  Our PMD segment's gross margin improved due to lower manufacturing variances, partially offset by unfavorable product mix resulting from lower sales of our industrial component sales.  Our AP segment's gross margin improved due to lower manufacturing expenses from increased production volumes, partially offset by an unfavorable product mix primarily due to an increase in sales of MOSFET products, which are typically lower margin products.  Our EP segment's gross margin improved primarily due to favorable product mix as a result of a much larger decrease in the computing components business than in the server business.  Our computing components business has lower gross margins than our server business.

For the three months ended March 24, 2013, our HiRel segment gross margin percentage decreased by 14.9 percentage points compared to the three months ended March 25, 2012 due to unusual production costs associated with a fabrication transfer. We anticipate that our margins will increase in the upcoming quarter back to recent prior historical levels.

Revenues and Gross Margin – Nine Months Ended

The following table summarizes revenues and gross margin by reportable segment for the nine months ended March 24, 2013 compared to the nine months ended March 25, 2012.  The amounts in the following table are in thousands:

Revenues

Revenues from all our segments, taken as a whole, decreased by $80.3 million, or 10.3 percent, attributed to revenues from our Customer Segments (which excludes the IP segment) decreasing by $81.8 million, or 10.5 percent, for the nine months ended March 24, 2013 as compared to nine months ended March 25, 2012.  Revenues for our Commercial Segments taken as a whole decreased 12.4 percent compared to the nine months ended March 25, 2012.  Revenues for our HiRel segment decreased 2.0 percent compared to the nine months ended March 25, 2012.

38

Within our Commercial Segments, AP revenue increased 7.3 percent for the nine months ended March 24, 2013 compared to the nine months ended March 25, 2012.  Revenues for our AP segment increased due to increased demand for new IGBT and MOSFET products.  Revenues for our ESP segment decreased 35.4 percent due to decreased demand in our consumer appliance related products resulting from a significant market slowdown in Asia and inventory reductions at our customers.  Revenues for our EP segment decreased 11.9 percent due to a decrease in demand for high performance computing and prior generation server components resulting from customer push outs and loss of market share in upcoming server generation components.   Revenues for our PMD segment decreased 1.9 percent due to a decrease in demand for our universal power supply and consumer products components.

For the nine months ended March 24, 2013, our HiRel segment revenues decreased 2.0 percent compared to the nine months ended March 25, 2012.

For the nine months ended March 24, 2013, our IP segment revenues increased $1.4 million or 112.7 percent, to $2.7 million. The increase in revenue arose from a one-time $1.7 million sale of patents.  We expect our IP segment revenues will be approximately $0.2 million per quarter in each of the next several quarters.  However, we do intend to continue to seek sale and/or licensing opportunities consistent with our business strategy.

Gross Margin

Our gross margin percentage decreased by 9.8 percentage points to 24.8 percent for the nine months ended March 24, 2013 compared to 34.6 percent for the nine months ended March 25, 2012.  This decrease in our gross margin percentage was the result of a decrease of 11.2 percentage points in gross margin for our Commercial Segments taken as a whole, and a decrease of 6.5 percentage points in gross margin for our HiRel segment.  The decrease in gross margin for all of our Commercial Segments was primarily due to increased costs associated with lower factory utilization, unfavorable change in product mix and increased inventory reserves.  Our ESP segment's gross margin declined due to unfavorable product mix as a result of decreased HVIC product demand which generally are higher margin products than our IGBT products.  Additionally, ESP has been particularly severely impacted by the underutilization of several of our manufacturing plants, including our recently closed fabrication facility in El Segundo, California.  As a result, we expect ESP gross margins to improve as our revenue grows and the effects of underutilization diminish.  Our AP segment's gross margin declined due to unfavorable product mix as a result of an increase in sales of our MOSFET products, which are typically lower margin products.  Our PMD segment's gross margin declined due to an unfavorable change in product mix as a result of reduced revenues from our industrial products, which have higher gross margins than our consumer components business, as well as price erosion.  Our EP segment's gross margin declined primarily due to unfavorable product mix as a result of a decrease in our server business, which has higher gross margins than our computing components business.

HiRel segment's gross margin percentage declined by 6.5 percentage points for the nine months ended March 24, 2013 compared to the nine months ended March 25, 2012 primarily due to unusual production costs associated with a fabrication transfer.

IP segment's gross margin percentage declined by 24.5 percentage points for the nine months ended March 24, 2013 compared to the nine months ended March 25, 2012 due to costs associated with the sale of patents.

Selling, General and Administrative Expense

(Dollars in thousands)	Selling, General and Administrative Expense
	March 24, 2013		% of Revenues			March 25, 2012		% of Revenues			Change
Three months ended	$	43,020		19.2	%	$	49,578		20.0	%	(0.8)ppt
Nine months ended	$	135,398		19.3	%	$	149,127		19.1	%	0.2ppt

SG&A expense decreased by $6.6 million and $13.7 million for the three and nine months ended March 24, 2013, respectively, compared to the prior year comparable period.  The decrease in SG&A expense was primarily due to a decrease in headcount related expenses as a result of the restructuring initiatives, decreased professional services and decreased travel expenses, partly offset by higher litigation expenses and increased stock compensation expense.  Additionally, depreciation increased by $2.8 million for the nine months ended March 24, 2013 due to the implementation of our ERP system at the beginning of the second quarter of fiscal year 2012. We expect our SG&A expenses to be about $47million in the fourth quarter of fiscal year 2013.

Research and Development Expense

(Dollars in thousands)	Research and Development Expense
	March 24, 2013		% of Revenues			March 25, 2012		% of Revenues			Change

Nine months ended	$	94,450		13.5	%	$	100,053		12.8	%	0.7ppt

 R&D expense decreased by $5.9 million and $5.6 million for the three and nine months ended March 24, 2013, respectively, compared to the prior year comparable period.  The decrease was primarily driven by lower headcount related expenses as a result of our restructuring initiatives and lower material costs, which were partly offset by the exhaustion of certain reimbursable grant funding at the end of fiscal year 2012, increased asset impairment expense, and increased stock compensation expense.  We expect our R&D expenses to be about $32million in the fourth quarter of fiscal year 2013.

Amortization of Acquisition-Related Intangible Assets

(Dollars in thousands)	Amortization of Acquisition-Related Intangible Assets

Nine months ended	$	5,023		0.7	%	$	6,651		0.9	%	(0.2)ppt

Amortization of acquisition-related intangible assets decreased $0.4 million and $1.6 million for the three and nine months ended March 24, 2013, respectively, compared to the prior year period, primarily a result of the full amortization of various intangible assets during the second half of fiscal year 2012. 

Asset Impairment, Restructuring and Other Charges

Asset impairment, restructuring and other charges reflect the impact of certain cost reduction programs and initiatives implemented by us.  These programs and initiatives include the closing of facilities, the termination of employees and other related activities.  Asset impairment, restructuring and other charges include program-specific exit costs, severance benefits pursuant to an ongoing benefit arrangement, and special termination benefits.  Severance costs unrelated to our restructuring initiatives are recorded as an element of cost of sales, research and development ("R&D") or selling, general and administrative expense ("SG&A"), depending upon the classification and function of the employee terminated.  Restructuring costs are expensed during the period in which all requirements of recognition are met.

During the first quarter of fiscal year 2013, we announced a restructuring plan to modify our manufacturing strategy and lower operating expenses in order to align our cost structure with business conditions.  As part of the plan, we expect to incur costs recorded in asset impairment, restructuring and other charges related primarily to the following:

· Fiscal Year 2013 El Segundo Fabrication Facility Closure Initiative

· Fiscal Year 2013 Newport Fabrication Facility Resizing Initiative

· Fiscal Year 2013 Other Cost Reduction Activities Initiative

Fiscal Year 2013 Initiatives

Fiscal Year 2013 El Segundo Fabrication Facility Closure Initiative

During the first quarter of fiscal year 2013, we adopted a restructuring plan to close our El Segundo wafer fabrication facility by the third quarter of fiscal year 2013.  In connection with the plan, we estimate to incur total pre-tax costs of $7.3 million.  These consist of $5.9 million of severance and workforce reduction costs, $1.2 million of relocation and re-qualification costs, and $0.2 million of asset impairment costs.   In addition to the restructuring charges above, during the three and nine months ended March 24, 2013, we recorded $0.2 million and $1.4 million of other charges related to the restructuring initiative in cost of sales.  These other charges, which were for accelerated depreciation and inventory write-downs are not classifiable as restructuring costs, and affected the ESP reporting segment.

During the three and nine months ended of March 24, 2013, cash payments for this initiative were $2.9 million and $5.3 million, respectively, and are estimated to be approximately $0.9 million and $1.0 million for the remainder of fiscal year 2013 and thereafter, respectively.  After the completion of this initiative, we estimate annual cost savings of approximately $10 million. These cost savings are the result of reduced manufacturing overhead costs, which will impact cost of sales.  We do not anticipate these overheadcost savings to be offset by additional costs incurred in other locations.

In addition, we estimate we will make cash expenditures of $2.5 million for the decontamination and restoration of this fabrication facility.  These costs were previously considered as part of the asset impairment of the El Segundo Fabrication Facility recorded in the fourth quarter of fiscal year 2012, and are not anticipated to result in additional restructuring charges.

Fiscal Year 2013 Newport, Wales Fabrication Facility Resizing Initiative

During the first quarter of fiscal year 2013, we adopted a restructuring plan to resize our wafer fabrication facility in Newport, Wales in several phases by the middle of calendar year 2015.  In connection with the plan, we estimate to incur total pre-tax costs of approximately $13.6 million.  These consist of approximately $0.7 million of asset impairment costs, $2.4 million of severance and workforce reduction costs, $4.4 million of decommissioning costs, and $6.1 million of relocation and re-qualification costs.

During the three and nine months ended March 24, 2013, cash payments for this initiative were $0.5 million and $1.7 million, respectively, and are estimated to be approximately $1.5 million and $9.7 million for the remainder of fiscal year 2013 and thereafter, respectively.  After the completion of this initiative, we estimate annual cost savings of approximately $16 million.  These cost savings are theresult of reduced manufacturing overhead costs, which will impact cost of sales.  We do not anticipate these cost savings to be offset by additional costs incurred in other locations.

42

Fiscal Year 2013 Other Cost Reduction Activities Initiative

During the first nine months of fiscal year 2013, we undertook certain actions to reduce (i) capacity at manufacturing facilities in Mexico, California, and Arizona, as well as (ii) administrative and research and development costs around the world.  As part of the plan, we incurred approximately $5.0 million of severance and workforce reduction costs so far in fiscal year 2013.  The severance and workforce reduction costs recorded during the three months ended March 24, 2013 included $0.2 million for research and development functions.  During the nine months ended March 24, 2013, severance and workforce reduction costs included $2.6 million related to manufacturing functions, $1.1 million for general and administrative functions, and $1.3 million for research and development functions.

As part of those ongoing efforts, during the nine months ended March 24, 2013, we incurred $1.1 million of asset impairment costs for the planned disposition of certain manufacturing equipment related to our manufacturing facility in Mexico, and may incur additional amounts in the future.

We have identified a few additional cost reduction actions to be implemented during the three months ending June 30, 2013, at which point this initiative is expected to be completed. 

During the three and nine months ended March 24, 2013, cash payments for this initiative were $1.1 million and $4.9 million, respectively, and are estimated to be approximately $0.2 million for the remainder of fiscal year 2013.  After the completion of this initiative, we estimate annual cost savings of approximately $18 million.  These cost cuts will result in reduced cost of sales, as well as lower SG&A and R&D expenses.  We do not anticipate these cost savings to be offset by additional costs incurred in other locations.

Other Expense, Net

Other expense (income), net includes, primarily, gains and losses related to foreign currency fluctuations and investment impairments.  Other income, net was $0.5 million and $0.0 million for the three months ended March 24, 2013 and March 25, 2012, respectively. Other income, net for the three months ended March 24, 2013 includes a release of tax indemnification reserves of $1.1 million, which was partly offset by a foreign currency exchange loss of $0.3 million due to fluctuations in foreign exchange currencies, and a cost-based investment impairment charge of $0.4 million.  The prior year comparable period included a foreign currency exchange loss of $0.2 million and a derivative impairment charge of $0.2 million, which were partially offset by a release of tax indemnification reserves.

Other expense, net was $1.0 million and $4.1 million for the nine months ended March 24, 2013 and March 25, 2012, respectively. Other expense, net for the nine months ended March 24, 2013 includes a foreign currency exchange loss of $1.9 million due to fluctuations in foreign exchange currencies, and a cost-based investment impairment charge of $0.4 million, which were partially offset by a release of tax indemnification reserves.  The prior year comparable period included a foreign currency exchange loss of $2.1 million due to fluctuations in foreign exchange currencies, and investment impairment charges of $2.4 million, which were partially offset by a release of tax indemnification reserves.

Interest Income, Net

Interest expense (income), net, was $0.1 million and $0.0 million for the three and nine months ended March 24, 2013, respectively, compared to interest expense (income), net, of $(0.0) million and $(0.3) million for the prior year comparable periods, respectively.

43

Income Taxes

We recorded a tax expense of $1.6 million or 8.1 percent against a loss of $19.6 million for the three months ended March 24, 2013.   The expense was mainly due to $1.9 million in foreign income taxes, $0.5 million in withholding taxes, and $0.2 million in domestic tax expense.  This expense was partially offset by a reduction in foreign uncertain tax positions, arising from lapses in statutes of limitation of approximately $0.6 million, and the utilization of a $0.4 million state tax credit.

We recorded a tax expense of $6.1 million or 8.0 percent against a loss of $76.6 million for the nine months ended March 24, 2013.  This was mainly due to a decrease in the United Kingdom ("U.K.") statutory tax rates, which reduced the value of our net deferred tax assets in the U.K. by $3.2 million, expenses related to foreign income taxes of $4.6 million, foreign withholding taxes of $2.0 million, and domestic tax expense of $1.4 million.  The expense was partially offset by the benefit of $4.7 million arising from a reduction in uncertain tax positions during the second and third quarters, and the utilization of a $0.4 million state tax credit.

We recorded a tax benefit of $4.5 million or 64.5 percent against a loss of $7.0 million for the three months ended March 25, 2012, and an expense of $2.8 million or 17.8 percent against income of $15.9 million for the nine months ended March 25, 2012.  For the three months ended March 25, 2012, we recorded a tax benefit of $4.5 million due to a valuation allowance release of $7.8 million related to deferred tax assets in the U.K., $3.1 million related to deferred tax assets in the U.S. and a $1.6 million benefit from an unrealized gain which was partially offset by $3.5 million in withholding taxes, $2.3 million in foreign taxes, $1.8 million of deferred charges, and $0.6 million increase in uncertain tax positions.  For the  nine months ended March 25, 2012, we recorded a tax expense of $2.8 million due to foreign taxes of $7.3 million, withholding taxes of $3.5 million, deferred charges of $1.8 million, an increase in uncertain tax positions of $1.4 million, tax rate changes that decreased our deferred tax assets by $0.6 million, and $0.6 million in domestic tax expense which was partially offset by the release of $10.9 million of valuation allowances and a $1.6 million benefit from an unrealized gain.

We operate in multiple foreign jurisdictions with lower statutory tax rates, and our operations in Singapore have the most significant impact on the effective tax rate.  We expect to be subject to an effective tax rate of 17 percent in Singapore for fiscal year 2013.

Liquidity and Capital Resources

Cash Requirements

Sources and Uses of Cash

We require cash to fund our operating expense and working capital requirements, capital expenditures, strategic growth initiatives, and funds to repurchase our common stock under our stock repurchase program.  Our primary sources for funding these requirements are cash and investments on hand and cash from operating activities.  On October 25, 2012 we entered into a $100 million unsecured revolving credit facility as discussed below.  To maintain the availability of the facility, we have to comply with a number of covenants and satisfy a number of conditions, including a minimum available liquidity requirement. We are currently in compliance with the financial tests and covenants contained in the revolving credit agreement.

Total cash, cash equivalents, and investments at March 24, 2013 and June 24, 2012 were as follows (in thousands):

	March 24, 2013		June 24, 2012
Cash and cash equivalents	$	386,994	$	305,423
Investments		15,058		78,926
Total cash, cash equivalents, and investments	$	402,052	$	384,349

As of March 24, 2013, we had $402.1 million of cash (excluding $1.4 million of restricted cash), cash equivalents and short-term and long-term investments, consisting of available-for-sale fixed income and investment‑grade securities, an increase of $17.7 million from June 24, 2012.  The increase in our cash and investments was primarily due to a $63.0 million reduction in inventory and a $33.5 million reduction in accounts receivable, significantly offset by our $76.6 million operating loss during the nine months ended March 24, 2013.  As of March 24, 2013, we had an increase of $81.6 million in cash and cash equivalents, and a decrease in investments of $63.9 million from June 24, 2012.  We reduced our investments and increased our cash and cash equivalents in the short-term in an effort to align our long-term investment strategy to preserve principal and maintain liquidity while achieving moderate returns on the investment portfolio.

We believe that our existing cash and cash equivalents will be sufficient to meet operating requirements and satisfy our existing balance sheet liabilities and other cash obligations for at least the next twelve months.  Our cash and cash equivalents are available to fund working capital needs, strategic growth initiatives, business acquisitions if any, repurchase of stock for our common stock repurchase program and capital expenditures.  During the nine months of fiscal year 2013, we have taken actions to meet our longer term revenue growth goals, including making capital investments in our manufacturing operations.  We plan to continue expanding our manufacturing capabilities for key technologies in anticipation of meeting our long term strategic goals.

Our outlook for the remainder of fiscal year 2013 is that our cash flow from operating activities in the final quarter will be positive.  We estimate that cash capital equipment expenditures for the fourth quarter of fiscal year 2013 will be about $15 million as we invest in new manufacturing process technologies.

Cash Flows

Our cash flows were as follows (in thousands):

	Nine Months Ended
	March 24, 2013			March 25, 2012
Cash flows provided by (used in) operating activities	$	81,631		$	(17,262	)

Cash flows used in financing activities		(2,360	)		(22,905	)
Effect of exchange rate changes on cash and cash equivalents		(720	)		(1,226	)
Net increase (decrease) in cash and cash equivalents	$	81,571		$	(81,231	)

45

Non-cash adjustments to cash flow generated by operating activities during the nine months ended March 24, 2013 included $68.6 million of depreciation and amortization, $16.4 million of stock compensation expense, and $15.3 million from the provision for inventory write-downs.  Changes in operating assets and liabilities increased cash provided by operating activities by $43.4 million, primarily attributed to decreases in trade accounts receivable and inventories, partially offset by decreases in accounts payable, accrued salaries, wages and benefits, accrued income taxes payable, and other accrued expenses.  These sources of cash flows from operations were partially offset by the net loss incurred during the period.

Cash provided by investing activities during the nine months ended March 24, 2013 was primarily the result of proceeds from the sale and maturities of investments of $73.6 million, almost fully offset by capital expenditures of $60.9 million and purchases of investments of $10.0 million.

Cash used in financing activities during the nine months ended March 24, 2013 of $2.4 million was primarily the result of cash used for stock repurchases under the stock repurchase program, partly offset by cash receipts from stock option exercises.

Revolving Credit Facility

On October 25, 2012 (the "Closing Date"), we entered into a Credit Agreement (the "Credit Agreement"), as borrower, with Wells Fargo Bank, National Association, as Administrative Agent ("Agent"), and certain lenders (the "Lenders"), pursuant to which we established a new senior unsecured revolving credit facility (the "Facility") in an aggregate principal amount of $100 million with sublimits for swingline loans (of $25 million) and the issuance of letters of credit (of $10 million).  The Credit Facility matures on October 25, 2016.

The proceeds of the Credit Facility may be used by us to finance certain capital expenditures and acquisitions permitted thereunder, to provide for the working capital and general corporate needs as well as to pay fees, commissions and expenses associated with the Credit Facility.

Outstanding amounts under the Credit Facility will initially bear interest at a rate per annum equal to, at our option, either (a) LIBOR plus 1.25 percent or (b) a "Base Rate" (equal to the greatest of (i) the Agent's prime rate; (ii) the federal funds rate plus 0.50 percent; and (iii) LIBOR plus 1.00 percent) plus 0.25 percent.  From and after our fiscal quarter ending on March 24, 2013, the margin over LIBOR and the Base Rate may be adjusted periodically based on our ratio of total funded debt to consolidated EBITDA as defined under the Credit Facility, with 1.75 percent per annum being the maximum LIBOR margin and 0.75 percent per annum being the maximum Base Rate margin established by such adjustment mechanism.  We are required to pay a commitment fee on the unused commitments under the Credit Facility at an initial rate equal to 0.25 percent per annum (subject to a similar leverage-based adjustment up to a maximum of 0.35 percent per annum).

The terms of the Credit Agreement require us (subject to certain limited exceptions and conditions) to comply with the following financial tests:  (i) maintenance of maximum total funded debt to consolidated EBITDA of not more than 2.50 to 1.0; (ii) maintenance of minimum consolidated EBITDA to consolidated interest charges of 4.00 to 1.0; and (iii) maintenance of minimum available liquidity of at least $200 million. Liquidity is generally defined as cash and cash equivalents, short-term investments and long-term investments (not to exceed $50 million), and the undrawn amount of the Credit Facility.  As a result of the requirement to comply with the financial tests, we will not be able to access the Credit Facility during periods where the financial tests, including the minimum liquidity threshold, are not met, thereby limiting our ability to draw on the line during a period of illiquidity or at any other time where the minimum liquidity threshold is not met.

In addition, the Credit Agreement contains certain covenants that, among other things, restrict additional indebtedness, liens and encumbrances, investments, acquisitions, loans and advances, mergers, consolidations and asset dispositions, dividends and other restricted payments, transactions with affiliates, capital expenditures (limited to between $175 million and $200 million per annum during the term of the Credit Facility) and other matters customarily restricted in such agreements, in each case, subject to certain customary exceptions.

The Credit Agreement also contains customary provisions related to: (i) events of default, including payment defaults, (ii) breaches of representations and warranties, (iii) covenant defaults, (iv) cross-defaults to certain material indebtedness in excess of specified amounts, (v) certain events of bankruptcy and insolvency, (vi) judgments in excess of specified amounts, (vii) certain impairments to the guarantees or collateral documents, and (viii) change in control defaults.

As of March 24, 2013, we were in compliance with the financial tests and covenants, and there were no amounts outstanding under the Credit Facility.

Working Capital

Our working capital is dependent on demand for our products and our ability to manage accounts receivable and inventories.  Other factors which may result in changes to our working capital levels are our restructuring initiatives, investment impairments and share repurchases.

The changes in working capital for the nine months ended March 24, 2013 were as follows (in thousands):

	March 24, 2013		June 24, 2012		Change
Current Assets
Cash and cash equivalents	$	386,994	$	305,423	$	81,571
Restricted cash		613		595		18
Short-term investments		15,058		63,872		(48,814	)
Trade accounts receivable, net		134,987		168,499		(33,512	)
Inventories		231,703		294,702		(62,999	)
Current deferred tax assets		5,040		5,110		(70	)
Prepaid expenses and other receivables		35,529		29,845		5,684
Total current assets	$	809,924	$	868,046	$	(58,122	)
Current Liabilities
Accounts payable		64,565	$	88,726	$	(24,161	)
Accrued income taxes		470		750		(280	)
Accrued salaries, wages and commissions		34,721		40,403		(5,682	)
Other accrued expenses		77,211		83,164		(5,953	)
Total current liabilities		176,967		213,043		(36,076	)
Net working capital	$	632,957	$	655,003	$	(22,046	)

For the changes in cash and investments, please see the discussions above under sources and uses of cash and cash flows.

The decrease in net trade accounts receivable of $33.5 million reflects the decrease in quarterly revenues of approximately 17 percent from the three months ended June 24, 2012 while our days-sales-outstanding decreased by approximately 2 days.

The decrease in inventories of $63.0 million included a $39.5 million decrease in finished goods, a $18.7 million decrease in work-in-process, and a $4.8 million decrease in raw materials.  Due to this decrease in inventory, inventory weeks decreased to approximately 18 weeks from 19 weeks.

The decrease in accounts payable of $24.2 million reflects reduced manufacturing activity, lower capital expenditures, and the timing of payments.

Other

In connection with certain tax matters described in Note 13, "Income Taxes," in the Notes to Unaudited Condensed Consolidated Financial Statements, we are pursuing refunds for income taxes we believe to have overpaid in certain jurisdictions. In these jurisdictions, we cannot determine that the realization of the tax refunds of $2.7 million is more likely than not and as such, we have not recognized them as income tax benefits in our consolidated financial statements.

47

Contractual Obligations

There has been no material change to our contractual obligations as disclosed in our 2012 Annual Report except as follows:

During the second quarter of fiscal year 2013, we entered into an operating lease agreement for a facility in Southeast Asia.  The total lease payments for the 10 year lease term effective March 1, 2013 will be approximately $14 million.

Off-Balance Sheet Arrangements

In the normal course of business, we enter into various operating leases for buildings and equipment.  In addition, we provide standby letters of credit or other guarantees as required for certain transactions.  We have historically provided cash collateral for any outstanding letters of credit.

Apart from the operating lease obligations and purchase commitments discussed in our 2012 Annual Report, we do not have any off-balance sheet arrangements as of March 24, 2013.

Recent Accounting Standards

Information set forth under Note 1, "Business, Basis of Presentation and Summary of Significant Accounting Policies— Recent Accounting Standards" in the Notes to Unaudited Condensed Consolidated Financial Statements is incorporated herein by reference.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP").  The preparation of condensed consolidated financial statements in accordance with GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosure of contingent assets and liabilities.  The U.S. Securities and Exchange Commission has defined critical accounting policies as those that "are both most important to the portrayal of the company's financial condition and results, and they require management's most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain."  As such, we have identified the following policies as our critical accounting policies:  Revenue recognition and allowances for sales returns and price concessions, fair value of financial instruments, impairment of long-lived assets, intangibles and goodwill, other-than-temporary impairments, inventory valuation, income taxes and loss contingencies.

The judgments and estimates we make in applying the accounting principles generally accepted in the U.S. affect the amounts of assets and liabilities reported, disclosures, and reported amounts of revenues and expenses.  As such, we evaluate the judgments and estimates underlying all of our accounting policies, including those noted above, on an ongoing basis.  We have based our estimates on the latest available historical information as well as known or foreseen trends; however, we cannot guarantee that we will continue to experience the same patterns in the future. If the historical data and assumptions we used to develop our estimates do not properly reflect future activity, our net sales, gross profit, net income and earnings per share could be materially and adversely impacted. Since the filing of our Annual Report on Form 10-K for the fiscal year ended June 24, 2012 on August 22, 2011, there have been no significant changes to our critical accounting policies and estimates.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rates

Our exposure to interest rate risk is primarily through our investment portfolio as we currently do not have outstanding long-term debt.  The objectives of our investments in debt securities are to preserve principal and maintain liquidity while achieving moderate returns on the investment portfolio.  To achieve these objectives, the returns on our investments in short-term fixed-rate debt securities will be generally compared to yields on money market instruments such as industrial commercial paper, LIBOR, or Treasury Bills.  Investments in longer term fixed-rate debt securities will be generally compared to yields on comparable maturity Government or high grade corporate instruments with an equivalent credit rating.  Based on our investment portfolio and interest rates at March 24, 2013, a 100 basis point increase or decrease in interest rates would result in an annualized change of approximately $0.1 million in the fair value of the investment portfolio.  Changes in interest rates may affect the fair value of the investment portfolio; however, unrealized gains or losses are not recognized in net income unless the investments are sold or the gains or losses are considered to be other-than-temporary.

Foreign Currency Exchange Rates

We hedge the risks of foreign currency denominated working capital positions with offsetting foreign currency denominated exchange transactions and currency forward contracts.  Exchange gains and losses on these foreign currency denominated working capital positions are generally offset by corresponding gains and losses on the related hedging instruments, usually resulting in negligible net exposure.  We do not hedge our revenues and expenses against changes in foreign currency exchange rates, as we do not perceive the net risk of changes to translated revenues and expenses from changes in exchange rates as significant enough at this time to justify hedging.

A significant amount of our revenues, expense, and capital purchasing transactions are conducted on a global basis in several foreign currencies.  At various times, we have currency exposure related mainly to the British Pound Sterling, the Euro and the Japanese Yen.  For example, in the United Kingdom we have a sales office and a semiconductor wafer fabrication facility with revenues primarily in U.S. Dollars and Euro and expenses in British Pound Sterling and U.S. Dollars.  To protect against exposure to currency exchange rate fluctuations on non-functional currency payables and receivables, we have established a balance sheet transaction risk hedging program.  This risk hedging program generally uses spot and currency forward contracts. These contracts are not designated as hedging instruments for accounting purposes.  Through our hedging program we seek to reduce, but do not always entirely eliminate, the impact of currency exchange rate movements.

For its balance sheet transaction risk hedging program, we had approximately $43.8 million in notional amounts of currency forward contracts not designated as accounting hedges at March 24, 2013. The net realized and unrealized foreign‑currency gains (losses) related to forward contracts not designated as accounting hedges recognized in earnings, as a component of other expense, were $2.1 million and $(0.0) million for the three and nine months ended March 24, 2013, respectively, and $(0.9) million and $(5.7) million for the three and nine months ended March 25, 2012, respectively.

 In the normal course of business, we also face risks that are either non-financial or non-quantifiable. Such risks principally include country risk, credit risk and legal risk and are not discussed or quantified in the preceding analysis. 

Market Value Risk

We carry certain assets at fair value.  Generally, for assets that are reported at fair value, we use quoted market prices or valuation models that utilize market data inputs to estimate fair value.  In certain cases quoted market prices or market data inputs may not be readily available or availability could be diminished due to market conditions.  In these cases, our estimate of fair value is based on best available information or other estimates determined by management.

At March 24, 2013, we had $402.1 million of total cash (excluding $1.4 million of restricted cash), cash equivalents and investments, consisting of available-for-sale fixed income securities.  We manage our total investment portfolio to encompass a diversified pool of investment‑grade securities. The average credit rating of our investment portfolio is AAA/Aaa.  Our investment policy is to manage our total cash and investment balances to preserve principal and maintain liquidity while achieving moderate returns on the investment portfolio.  Additionally, there are certain equity investments in our portfolio which continue to have strategic value, and we generally do not attempt to reduce or eliminate our market exposure in these investments.  For securities that we no longer consider strategic, we evaluate legal, market, and economic factors in our decision on the timing of disposal.  We may or may not enter into transactions to reduce or eliminate the market risks of our investments.

49

During the three and nine months ended March 24, 2013, there was no other-than-temporary impairment to our market priced available-for-sale securities. See Part I, Item 1A, "Risk Factors—Our investments in certain securities expose us to market risks", set forth in our 2012 Annual Report.

ITEM 4.  CONTROLS AND PROCEDURES

This Report includes the certifications of our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO") required by Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act").  See Exhibits 31.1 and 31.2.  This Item 4 includes information concerning the controls and control evaluations referred to in those certifications.

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including the CEO and CFO, to allow timely decisions regarding required disclosures.

Our management, under the supervision and with the participation of our CEO and CFO, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of March 24, 2013.  Based upon this evaluation, our CEO and CFO concluded that, as of March 24, 2013, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

"Internal control over financial reporting" is a process designed by, or under the supervision of, our CEO and CFO, and effected by our board of directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of assets;

(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of management and our directors; and

(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

During the fiscal quarter ended March 24, 2013 there were no changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations Over Internal Controls

We do not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors.  A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.  Further, the design of a control system must acknowledge the fact that there are resource constraints and the benefits of controls must be considered relative to their costs.  These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake.  Controls can also be circumvented by the deliberate acts of one or more persons.  The design of any system of controls is based, in part, upon certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.  Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with associated policies or procedures.  Because of the inherent limitations in a cost-effective control system, misstatements due to error may occur and not be detected.

Business, Basis of Presentation and Summary of Significant Accounting Policies [Abstract]

Basis of Presentation

The condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"), and therefore do not include all information and notes normally provided in audited financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, which are located in North America, Europe and Asia. Intercompany balances and transactions have been eliminated in consolidation.

In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation of the Company's results of operations, financial position, and cash flows have been included.  The results of operations for the interim periods presented are not necessarily comparable to the results of operations for any other interim period or indicative of the results that will be recorded for the full fiscal year ending June 30, 2013. These condensed consolidated financial statements and the accompanying notes should be read in conjunction with the Company's annual consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended June 24, 2012 filed with the SEC on August 23, 2012 (the "2012 Annual Report").

Fiscal Year and Quarter

The Company operates on a 52-53 week fiscal year with the fiscal year ending on the last Sunday in June. The three months ended March 2013 and 2012 consisted of 13 weeks ending on March 24, 2013 and March 25, 2012, respectively.  The current fiscal year will consist of 53 weeks and end on June 30, 2013.

Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported revenues and expenses during the reporting period. Actual results could differ from those estimates.

Subsequent Events

The Company evaluates events subsequent to the end of the fiscal quarter through the date the financial statements are filed with the SEC for recognition or disclosure in the consolidated financial statements.  Events that provide additional evidence about material conditions that existed at the date of the balance sheet are evaluated for recognition in the consolidated financial statements.  Events that provide evidence about conditions that did not exist at the date of the balance sheet but occurred after the balance sheet date are evaluated for disclosure in the notes to the consolidated financial statements.

Financial Assets and Liabilities Measured at Fair Value

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  Assets and liabilities measured at fair value are categorized based on whether the inputs are observable in the market and the degree to which the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels (with Level 3 being the lowest) defined as follows:

· Level 1—Inputs are based on quoted market prices for identical assets or liabilities in active markets at the measurement date.

· Level 2—Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.

· Level 3—Inputs include management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument's valuation.

When at least one significant valuation model assumption or input used to measure the fair value of financial assets or liabilities is unobservable in the market, they are deemed to be measured using Level 3 inputs.  These Level 3 inputs may include pricing models, discounted cash flow methodologies or similar techniques where at least one significant model assumption or input is unobservable.  The Company uses Level 3 inputs to value financial assets that include a non-transferable put option on a strategic investment (the "Put Option") and a liability for an acquisition-related contingent consideration arrangement.  Level 3 inputs were also used to value investment securities that included a certain asset-backed security for which there was decreased observability of market pricing for these investments.

The Company accounts for the Put Option as a derivative instrument not designated as an accounting hedge.  The fair value was determined using the Black-Scholes option pricing model.  The model uses inputs such as exercise price, fair market value of the underlying common stock, expected life (years), expected volatility, risk-free rate equivalent, and dividend yield.  The expected life is the remaining life of the Put Option.  Expected volatility is based on historical volatility of the underlying common stock.  As of March 24, 2013, the Company determined that significant changes in the above assumptions would not materially affect the fair value of the Put Option.  Additionally, the model materially relies on the assumption the issuer of the Put Option will uphold its financial obligation up to its common equity value should the Company exercise the Company's right to put the associated number of common shares back to the issuer at a fixed price in local currency.

For the three and nine months ended March 24, 2013, the Company measured at fair value, on a non-recurring basis, the carrying values of certain equipment in its research and development group, its Newport, Wales, and Mexico manufacturing facilities, and a subcontractor facility located in southeast Asia, due to the non-use of that equipment.  During the three months ended March 24, 2013, the Company determined that the carrying values of certain assets located at the subcontractor facility of $0.3 million exceeded their estimated fair values of zero.  The fair values were determined using the market approach, which considered the estimated fair value of the equipment using significant unobservable inputs (Level 3) obtained from third party equipment brokerage firms.  In addition to the above, during the six months ended December 23, 2012, the Company determined that the carrying values of certain assets in its research and development group, and manufacturing facilities located in Newport, Wales, and Mexico of $8.7 million exceeded their estimated fair values of $4.0 million.  The fair values were determined using the market approach, which considered the estimated fair value of the equipment using significant unobservable inputs (Level 3) obtained from third party equipment brokerage firms.  Consequently, during the three and nine months ended March 24, 2013, the Company recorded impairment charges of $0.3 million and $5.0 million, respectively, which represents the excess of the carrying values of the assets over the fair values, less the estimated cost to sell.  The Company had no significant measurements of assets or liabilities at fair value on a non-recurring basis during the three months and nine months ended March 25, 2012.

Derivative Financial Instruments [Abstract]

Derivative Financial Instruments

3. Derivative Financial Instruments

The Company is exposed to financial market risks, including fluctuations in interest rates, foreign currency exchange rates and market value risk related to its investments.  The Company uses derivative financial instruments primarily to mitigate foreign exchange rate risks, but also as part of its strategic investment program.  In the normal course of business, the Company also faces risks that are either non-financial or non-quantifiable.  Such risks principally include country risk, credit risk and legal risk, and are not discussed or quantified in the following analyses.  As of March 24, 2013, the Company's only derivatives were currency forward contracts which were not designated as accounting hedges, the Put Option (See Note 2, "Investments"), and a call option on the equity of a private domestic company.  The private domestic company is a development stage entity, and as such, the Company is unable to determine the fair value of the call option at this time.

Interest Rates

The Company is subject to interest rate risk through its investments.  The objectives of the Company's investments in debt securities are to preserve principal and maintain liquidity while maximizing returns.  To achieve these objectives, the returns on the Company's investments in short-term debt generally will be compared to yields on money market instruments such as U.S. Commercial Paper programs, LIBOR, or U.S. Treasury Bills.  Investments in long-term debt securities will be generally compared to yields on comparable maturity of U.S. Treasury obligations, investment grade corporate instruments with an equivalent credit rating or an aggregate benchmark index.

The Company had no outstanding interest rate derivatives as of March 24, 2013.

3. Derivative Financial Instruments (Continued)

Foreign Currency Exchange Rates

The Company generally hedges the risks of foreign currency-denominated repetitive working capital positions with offsetting foreign currency denominated exchange transactions, using currency forward contracts or spot transactions.  Transaction gains and losses on these foreign currency-denominated working capital positions are generally offset by corresponding gains and losses on the related hedging instruments, usually resulting in reduced net exposure.  The Company does not hedge its revenues and expenses against changes in foreign currency exchange rates, as it does notperceive the net risk of changes to translated revenues and expenses from changes in exchange rates as significant enough at this time to justify hedging.

A significant amount of the Company's revenues, expense, and capital purchasing transactions are conducted on a global basis in several foreign currencies.  At various times, the Company has currency exposure related to the British Pound Sterling, the Euro, and the Japanese Yen.  For example, in the United Kingdom, the Company has a sales office and a semiconductor wafer fabrication facility with revenues in U.S. Dollars and Euros, and expenses in British Pounds Sterling and U.S. Dollars.  To protect against exposure to currency exchange rate fluctuations on non-functional currency payables and receivables, the Company has established a balance sheet transaction risk hedging program.  This risk hedging program generally uses spot and currency forward contracts.  These contracts are not designated as hedging instruments for accounting purposes.  Through this hedging program, the Company seeks to reduce, but does not always entirely eliminate, the impact of currency exchange rate movements.

For its balance sheet transaction risk hedging program, the Company had approximately $43.8 million in notional amounts of currency forward contracts not designated as accounting hedges at March 24, 2013.  The net realized and unrealized foreign‑currency gains (losses) related to forward contracts not designated as accounting hedges recognized in earnings, as a component of other expense (income), net, were $2.1 million and $(0.0) million for the three and nine months ended March 24, 2013, respectively, and $(0.9) million and $(5.7) million for the three and nine months ended March 25, 2012, respectively.

At March 24, 2013 and June 24, 2012, the fair value carrying amount of the Company's derivatives not designated as hedging instruments were as follows (in thousands):

	March 24, 2013			June 24, 2012

The gain or (loss) recognized in other expense (income), net for the Company's derivatives not designated as hedging instruments during the three and nine months ended March 24, 2013 and March 25, 2012 was comprised of the following (in thousands):

2. Investments

Available-for-sale investments are carried at fair value, inclusive of unrealized gains and losses, and net of discount accretion and premium amortization computed using the level yield method. Net unrealized gains and losses are included in other comprehensive income (loss) net of applicable income taxes. Gains or losses on sales of available-for-sale investments are recognized using the first-in, first-out method and are included in either other income or interest income depending upon the type of security.

Available-for-sale securities as of March 24, 2013 are summarized as follows (in thousands):

2. Investments (Continued)

The Company manages its total portfolio to encompass a diversified pool of investment‑grade securities. The investment policy is to manage its total cash and investments balances to preserve principal and maintain liquidity while achieving moderate returns on the investment portfolio.

In addition, the Company has a note receivable from a privately held company which was carried at cost of $0.4 million in other assets.  This investment was carried at cost as the Company determined that it was nonmarketable since the issuer is a start-up company whose securities are not publicly traded, and as a result, it was not practicable to estimate the fair value of the investment.  During the three months ended March 24, 2013, the privately held company in which the Company has an equity investment experienced a negative change in financial condition.  The Company then evaluated that the investment was permanently impaired and recorded an impairment charge of $0.4 million during the three months ended March 24, 2013.

The Company also holds as strategic investments the common stock of three publicly traded foreign companies.  The common stock of the three companies are shown as "Equity securities" in the tables above and are included in other assets on the consolidated balance sheets.  The common shares of the publicly traded companies are traded on either the Tokyo Stock Exchange or the Taiwan Stock Exchange.  The Company holds an option on one of the strategic investments to put the associated number of common shares back to the issuer at a fixed price in local currency (which is described as the "Put Option" in Note 1).  The Put Option became effective September 1, 2009 and is reported at fair value.  As of March 24, 2013, the fair value of the Put Option was $2.9 million, with changes in fair value recorded in other expense (income), net (See Note 3, "Derivative Financial Instruments").  Dividend income from these investments was $0.1 million and $0.2 million for the three and nine months ended March 24, 2013, respectively, and $0.1 million for the nine months ended March 25, 2012.  The Company received no dividend income from these equity investments during the three months ended  March 25, 2012.

The Company evaluates securities for other-than-temporary impairment on a quarterly basis. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include the length of time and extent to which the market value has been less than cost; the financial condition and near-term prospects of the issuer of the securities; and the intent and ability of the Company to retain the security in order to allow for an anticipated recovery in fair value. If, based upon the analysis, it is determined that the impairment is other-than-temporary, the security is written down to fair value, and a loss is recognized through earnings.

The following table provides the Company's other-than-temporary impairments for equity and mortgage-backed securities for the three and nine months ended March 24, 2013 and March 25, 2012 (in thousands):

	Three Months Ended				Nine Months Ended

The unrealized loss position is measured and determined at each fiscal quarter end.  The following tables summarize the fair value and gross unrealized losses related to available-for-sale investments, aggregated by type of investment and length of time that individual securities have been held (in thousands):

	Securities heldin a loss positionfor less than12 months atMarch 24, 2013					Securities heldin a loss positionfor 12 monthsor more atMarch 24, 2013				Total in a loss positionat March 24, 2013

Total	$	46,420	$	(11	)	$	—	$	—	$	46,420	$	(11	)

As of March 24, 2013, the Company evaluated whether equity securities with gross unrealized losses of $0.2 million was other-than-temporarily impaired.  The Company determined there was no indication of other-than-temporary impairment with regards to gross unrealized losses.  The determination was based on the fact the Company has evaluated the near-term prospects of the equity investments in relation to the severity and duration of the impairment, and based on that evaluation, has the ability and intent to hold these investments until a recovery of fair value.

The amortized cost and estimated fair value of investments at March 24, 2013, by contractual maturity, are as follows (in thousands):

	AmortizedCost		EstimatedMarket Value
Due in 1 year or less	$	15,053	$	15,058
Total investments	$	15,053	$	15,058

The Company may decide to dispose of securities prior to the contractual maturity date indicated in the table above.

During the nine months ended March 24, 2013, available-for-sale securities were sold for total proceeds of $52.1 million, and for the three and nine months ended March 25, 2012 were sold for total proceeds of $12.2 million and $27.1 million, respectively.  During the three months ended March 24, 2013, there were no sales of available-for-sale securities, and as a result, the Company did not recognize any gross realized gains (losses).  Gross realized gains (losses) for the nine months ended March 24, 2013 and March 25, 2012 were de minimis.

2. Investments (Continued)

As a result of sales of available-for-sale securities, the Company reclassified $0.0 million for the nine months ended March 24, 2013, and $(0.0) million and $(0.2) million for the three and nine months ended March 25, 2012, respectively, from accumulated other comprehensive income to earnings as a component of interest income.  During the three months ended March 24, 2013, the Company did not reclassify realized gains (losses) from accumulated other comprehensive income to earnings, as there were no sales of available-for-sale securities.

Litigation [Abstract]

Litigation

16. Litigation

EPC/Lidow Litigation.

In September 2008, the Company filed suit in the U.S. District Court for the Central District of California against Efficient Power Conversion Corp. ("EPC"), certain of EPC's employees and other defendants (including Alex Lidow, a former chief executive officer and director of the Company, and now a principal of EPC) alleging improper and  unauthorized use and/or misappropriation of certain Company confidential information, trade secrets and technology related to the Company's Gallium Nitride development program.  In 2009, the Company refiled the suit in the Los Angeles Superior Court, Case No. BC409749.  Alex Lidow and EPC asserted claims against the Company arising out of Lidow's employment with and separation from the Company, for violations of the California Labor Code and California Business and Professions Code, and alleging the Company unfairly competed and interfered with EPC. Those claims have been consolidated with and in the Company's action.

In January 2012, the trial court granted summary adjudication in favor of the Company on the wrongful termination cause of action filed by Lidow; however, on June 23, 2012, the Court of Appeal filed a writ of mandate directing that the trial court's order be vacated and that a new order denying summary adjudication be entered.  The Company subsequently filed a petition for review in the California Supreme Court, which was denied.

Discovery is ongoing, and the Company intends to vigorously pursue all rights and defenses available to it in these matters.

Angeles v. Omega.  See Note 15, "Environmental Matters."

In addition to the above, the Company is involved in certain legal matters that arise in the ordinary course of business. The Company intends to pursue its rights and defend against any claims brought by third parties vigorously. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, the Company's business, financial condition, results of operations or cash flows could be materially and adversely affected.

Stock Repurchase Program [Abstract]

Stock Repurchase Program

18. Stock Repurchase Program

The Company's stock repurchase program authorizes it to repurchase up to $150.0 million of common stock. Stock repurchases under this program may be made in the open market or through privately negotiated transactions. The timing and actual number of shares repurchased depend on market conditions and other factors. The stock repurchase program may be suspended at any time without prior notice. The Company has used and plans to continue to use existing cash to fund the repurchases. All of the shares repurchased by the Company through the program were purchased in open market transactions. For the nine months ended March 24, 2013, the Company repurchased approximately 0.3 million shares for approximately $5.2 million, and to date the Company has purchased approximately 6.2 million shares for approximately $113.2 million under the program.  During the three months ended March 24, 2013, the Company did not repurchase any shares under the stock repurchase program.  As of March 24, 2013, the Company had not cancelled the repurchased shares of common stock, and as such, they are reflected as treasury stock in the March 24, 2013 and June 24, 2012 consolidated condensed balance sheets.

1. Business, Basis of Presentation and Summary of Significant Accounting Policies

Business

International Rectifier Corporation ("IR" or the "Company") designs, manufactures and markets power management semiconductors.  Power management semiconductors address the core challenges of power management, power performance and power conservation, by increasing system efficiency, allowing more compact end-products, improving features on electronic devices and prolonging battery life.

Power semiconductors convert raw power from an electrical outlet, a battery, an alternator running off an internal combustion engine, a hybrid electric vehicle ("HEV") or electric vehicle ("EV"), or other renewable energy sources into more efficient and useful power for a wide range of electrical and electronic systems and equipment. The more sophisticated the end product, the greater the need for specially-formatted, finely-regulated power. The importance of power semiconductor technology rises with the increasing complexity of electronic products and the proliferation of electronic features in information technology, industrial, consumer, aerospace and defense and automotive products.

With the demand for energy usage increasing worldwide and energy costs generally rising, governments and consumers alike are striving to conserve energy and demand more efficient uses of power in all types of electronic products including computers, appliances, military aircraft, and hybrid cars. The information technology, industrial, computing, consumer, high reliability and automobile industries use power management semiconductors to promote energy efficiency and improve performance metrics.  Power management semiconductors enable energy savings by delivering the power tailored for a particular electrical device, rather than delivering a constant stream of power.

The Company's products include power metal oxide semiconductor field effect transistors ("MOSFETs"), high voltage analog and mixed signal integrated circuits ("HVICs"), low voltage analog and mixed signal integrated circuits ("LVICs"), digital integrated circuits ("ICs"), radiation‑resistant ("RAD-Hard") power MOSFETs, insulated gate bipolar transistors ("IGBTs"), high reliability DC-DC converters, digital controllers, integrated power modules, and automotive product packages.

Basis of Presentation

The condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"), and therefore do not include all information and notes normally provided in audited financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, which are located in North America, Europe and Asia. Intercompany balances and transactions have been eliminated in consolidation.

In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation of the Company's results of operations, financial position, and cash flows have been included.  The results of operations for the interim periods presented are not necessarily comparable to the results of operations for any other interim period or indicative of the results that will be recorded for the full fiscal year ending June 30, 2013. These condensed consolidated financial statements and the accompanying notes should be read in conjunction with the Company's annual consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended June 24, 2012 filed with the SEC on August 23, 2012 (the "2012 Annual Report").

Fiscal Year and Quarter

The Company operates on a 52-53 week fiscal year with the fiscal year ending on the last Sunday in June. The three months ended March 2013 and 2012 consisted of 13 weeks ending on March 24, 2013 and March 25, 2012, respectively.  The current fiscal year will consist of 53 weeks and end on June 30, 2013.

Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported revenues and expenses during the reporting period. Actual results could differ from those estimates.

1. Business, Basis of Presentation and Summary of Significant Accounting Policies (Continued)

Subsequent Events

The Company evaluates events subsequent to the end of the fiscal quarter through the date the financial statements are filed with the SEC for recognition or disclosure in the consolidated financial statements.  Events that provide additional evidence about material conditions that existed at the date of the balance sheet are evaluated for recognition in the consolidated financial statements.  Events that provide evidence about conditions that did not exist at the date of the balance sheet but occurred after the balance sheet date are evaluated for disclosure in the notes to the consolidated financial statements.

Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  Assets and liabilities measured at fair value are categorized based on whether the inputs are observable in the market and the degree to which the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels (with Level 3 being the lowest) defined as follows:

· Level 1—Inputs are based on quoted market prices for identical assets or liabilities in active markets at the measurement date.

· Level 2—Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.

· Level 3—Inputs include management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument's valuation.

The financial assets and liabilities which are measured and recorded at fair value on a recurring basis are included within the following items on the Company's consolidated balance sheet as of March 24, 2013 and June 24, 2012 (in thousands):

	As of March 24, 2013

The Company considers as cash and cash equivalents all investments that are highly liquid with an initial maturity of three months or less from the date of purchase.

The fair value of investments, derivatives, and other assets and liabilities are disclosed in Note 2, Note 3, and Note 9, respectively.

During the nine months ended March 24, 2013 and March 25, 2012, for each class of assets and liabilities, there were no transfers between those valued using quoted prices in active markets for identical assets (Level 1), those valued using significant other observable inputs (Level 2), and those valued using significant unobservable inputs (Level 3).  The Company determines at the end of the reporting period whether a given financial asset or liability is valued using Level 1, 2, or 3 inputs.

As of March 24, 2013, the Company's investments recorded at fair value using Level 2 inputs included corporate debt securities and U.S. government agency obligations.  The above assets and liabilities recorded at fair value using Level 2 inputs were valued primarily using an independent valuation firm based on the market approach using various inputs such as trade data, broker/dealer quotes, observable market prices for similar securities and other available data.  The Company also records its foreign currency forward contracts at fair value using Level 2 inputs based on readily observable market parameters for all substantial terms of derivatives.

When at least one significant valuation model assumption or input used to measure the fair value of financial assets or liabilities is unobservable in the market, they are deemed to be measured using Level 3 inputs.  These Level 3 inputs may include pricing models, discounted cash flow methodologies or similar techniques where at least one significant model assumption or input is unobservable.  The Company uses Level 3 inputs to value financial assets that include a non-transferable put option on a strategic investment (the "Put Option") and a liability for an acquisition-related contingent consideration arrangement.  Level 3 inputs were also used to value investment securities that included a certain asset-backed security for which there was decreased observability of market pricing for these investments.

The Company accounts for the Put Option as a derivative instrument not designated as an accounting hedge.  The fair value was determined using the Black-Scholes option pricing model.  The model uses inputs such as exercise price, fair market value of the underlying common stock, expected life (years), expected volatility, risk-free rate equivalent, and dividend yield.  The expected life is the remaining life of the Put Option.  Expected volatility is based on historical volatility of the underlying common stock.  As of March 24, 2013, the Company determined that significant changes in the above assumptions would not materially affect the fair value of the Put Option.  Additionally, the model materially relies on the assumption the issuer of the Put Option will uphold its financial obligation up to its common equity value should the Company exercise the Company's right to put the associated number of common shares back to the issuer at a fixed price in local currency.

For the three and nine months ended March 24, 2013, the Company measured at fair value, on a non-recurring basis, the carrying values of certain equipment in its research and development group, its Newport, Wales, and Mexico manufacturing facilities, and a subcontractor facility located in southeast Asia, due to the non-use of that equipment.  During the three months ended March 24, 2013, the Company determined that the carrying values of certain assets located at the subcontractor facility of $0.3 million exceeded their estimated fair values of zero.  The fair values were determined using the market approach, which considered the estimated fair value of the equipment using significant unobservable inputs (Level 3) obtained from third party equipment brokerage firms.  In addition to the above, during the six months ended December 23, 2012, the Company determined that the carrying values of certain assets in its research and development group, and manufacturing facilities located in Newport, Wales, and Mexico of $8.7 million exceeded their estimated fair values of $4.0 million.  The fair values were determined using the market approach, which considered the estimated fair value of the equipment using significant unobservable inputs (Level 3) obtained from third party equipment brokerage firms.  Consequently, during the three and nine months ended March 24, 2013, the Company recorded impairment charges of $0.3 million and $5.0 million, respectively, which represents the excess of the carrying values of the assets over the fair values, less the estimated cost to sell.  The Company had no significant measurements of assets or liabilities at fair value on a non-recurring basis during the three months and nine months ended March 25, 2012.

Adoption of Recent Accounting Standards

In June 2011, the FASB issued ASC update No. 2011-05, "Comprehensive Income (Topic 220), Presentation of Comprehensive Income" ("ASC 2011-05").  The FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity, among other amendments in this update.  The amendments require that all non-owner changes in stockholder's equity be presented in a single continuous statement of comprehensive income or in two separate but consecutive statements.  In both alternatives, a company is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income.  A company is also required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of comprehensive income are presented.  The adoption of this update did not have a material impact on the Company's financial statements, and the statement of comprehensive income was presented as a separate consecutive statement following the unaudited condensed consolidated statements of operations (See Part I, Item 1, Financial Statements- "Unaudited Condensed Consolidated Statements of Comprehensive Income").

Recent Accounting Standards

In July 2012, the FASB issued ASC update No. 2012-02, "Intangibles-Goodwill and Other (Topic 350), Testing Indefinite-Lived Intangible Assets for Impairment" ("ASC 2012-02").  Under the amendments in this update, a company has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Topic 350.  The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent.  If after assessing the qualitative factors, a company determines it does not meet the more-likely-than-not threshold, a company is required to perform the quantitative impairment test by calculating the fair value of an indefinite-lived intangible asset and comparing the fair value with the carrying amount of the asset.  The amendments in this update are effective for annual and interim impairment test performed for fiscal years beginning after September 15, 2012 (early adoption permitted).  The Company does not believe that adoption of this update will have a material impact on its financial statements.

In February 2013, the FASB issued ASC update No. 2013-02, "Comprehensive Income (Topic 220), Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" (ASC 2013-02).  The objectives of this update require companies to provide information about the amounts reclassified out of accumulated other comprehensive income by component.  In addition, a company is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. The amendments in this update are effective for fiscal years and interim periods within those years beginning after December 15, 2012.  The Company does not believe that adoption of this update will have a material impact on its financial statements.

Asset Impairment, Restructuring and Other Charges [Abstract]

Asset Impairment, Restructuring and Other Charges

11. Asset Impairment, Restructuring and Other Charges

Asset impairment, restructuring and other charges reflect the impact of certain cost reduction programs and initiatives implemented by the Company.  These programs and initiatives include the closing of facilities, the termination of employees and other related activities.  Asset impairment, restructuring and other charges include program-specific exit costs, severance benefits pursuant to an ongoing benefit arrangement, and special termination benefits.  Severance costs unrelated to the Company's restructuring initiatives are recorded as an element of cost of sales, research and development ("R&D") or selling, general and administrative expense ("SG&A"), depending upon the classification and function of the employee terminated.  Restructuring costs are expensed during the period in which all requirements of recognition are met.

Asset write-downs are principally related to facilities and equipment that will not be used subsequent to the completion of exit or downsizing activities being implemented, and cannot be sold for amounts in excess of carrying value.  In determining the asset groups for the purpose of calculating write-downs, the Company groups assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities.  In determining whether an asset is impaired, the Company evaluates estimated undiscounted future cash flows and other factors such as changes in strategy and technology. An impairment loss exists if the estimated undiscounted future cash flows are less than the carrying amount of the asset group. The Company then determines the fair value of the asset group by discounting the estimated future cash flows, consistent with the cash flows of a market participant, at a discount rate that is used when analyzing potential acquisitions. The Company then compares the fair value of the asset group with the carrying amount of the asset group and writes down the carrying amount of the asset group to its fair value.

During the first quarter of fiscal year 2013, the Company announced a restructuring plan to modify its manufacturing strategy and lower its operating expenses in order to align its cost structure with business conditions.  As part of the plan, the Company expects to incur costs recorded in asset impairment, restructuring and other charges related primarily to the following:

•Fiscal Year 2013 El Segundo Fabrication Facility Closure Initiative

•Fiscal Year 2013 Newport Fabrication Facility Resizing Initiative

•Fiscal Year 2013 Other Cost Reduction Activities Initiative

The following tables summarize the total asset impairment, restructuring and other charges by initiative for the three and nine months ended March 24, 2013 (in thousands):

Fiscal Year 2013 Initiatives

Fiscal Year 2013 El Segundo Fabrication Facility Closure Initiative

During the first quarter of fiscal year 2013, the Company adopted a restructuring plan to close its El Segundo wafer fabrication facility by the third quarter of fiscal year 2013.  In connection with the plan, the Company estimates it will incur total pre-tax costs of $7.3 million.  These costs consist of $5.9 million of severance and workforce reduction costs, $1.2 million of relocation and re-qualification costs, and $0.2 million of asset impairment costs. In addition to the restructuring charges above, during the three and nine months ended March 24, 2013, the Company recorded $0.2 million and $1.4 million of other charges related to the restructuring initiative in cost of sales.  These other charges, which were for accelerated depreciation and inventory write-downs, are not classifiable as restructuring costs, and affected the ESP reporting segment.

During the three and nine months ended March 24, 2013, cash payments for this initiative were $2.9 million and $5.3 million, respectively, and are estimated to be approximately $0.9 million and $1.0 million for the remainder of fiscal year 2013 and thereafter, respectively.

In addition, the Company estimates it will make cash expenditures of $2.5 million for the decontamination and restoration of this fabrication facility.  These costs were previously considered as part of the asset impairment of the El Segundo Fabrication Facility recorded in the fourth quarter of fiscal year 2012, and are not anticipated to result in additional restructuring charges.

Fiscal Year 2013 Newport, Wales Fabrication Facility Resizing Initiative

During the first quarter of fiscal year 2013, the Company adopted a restructuring plan to resize its wafer fabrication facility in Newport, Wales in several phases by the middle of calendar year 2015.  In connection with the plan, the Company estimates it will incur total pre-tax costs of approximately $13.6 million.  These costs consist of approximately $0.7 million of asset impairment costs, $2.4 million of severance and workforce reduction costs, $4.4 million of decommissioning costs, and $6.1 million of relocation and re-qualification costs.

During the three and nine months ended March 24, 2013, cash payments for this initiative were $0.5 million and $1.7 million, respectively, and are estimated to be approximately $1.5 million and $9.7 million for the remainder of fiscal year 2013 and thereafter, respectively.

Fiscal Year 2013 Other Cost Reduction Activities Initiative

During the first nine months of fiscal year 2013, the Company undertook certain actions to reduce (i) capacity at manufacturing facilities in Mexico, California, and Arizona, as well as (ii) administrative and research and development costs around the world.  As part of the plan, the Company has incurred approximately $5.0 million of severance and workforce reduction costs so far in fiscal year 2013.  The severance and workforce reduction costs recorded during the three months ended March 24, 2013 included $0.2 million for research and development functions.  During the nine months ended March 24, 2013, severance and workforce reduction costs included $2.6 million related to manufacturing functions, and $1.1 million for general and administrative functions, and $1.3 million for research and development functions.

As part of those ongoing efforts, during the nine months ended March 24, 2013, the Company incurred $1.1 million of asset impairment costs for the planned disposition of certain manufacturing equipment related to its manufacturing facility in Mexico, and may incur additional amounts in the future.

The Company has identified a few additional cost reduction actions to be implemented during the three months ending June 30, 2013, at which point this initiative is expected to be completed. 

During the three and nine months ended March 24, 2013, cash payments for this initiative were $1.1 million and $4.9 million, respectively, and are estimated to be approximately $0.2 million for the remainder of fiscal year 2013.

Enterprise Power ("EP") – The EP segment's primary applications include servers, storage, routers, switches, infrastructure equipment, notebooks, graphic cards, and gaming consoles.  The Company offers a broad portfolio of power management system products that deliver benchmark power density, efficiency and performance. These products include the Company's DirectFET® discrete products, CHil digital PWM controllers, power monitoring products, XPhase®, SupIRBuckTM, iPOWIR® voltage regulators, Low voltage ICs, and PowIRstagesTM.

HiRel - The HiRel segment provides high-reliability power components and sub-assemblies designed to address power management requirements in mission critical applications including satellites and space exploration vehicles, military hardware and other high reliability applications such as commercial aircraft, undersea telecommunications, and oil drilling in heavy industry and products used in biomedical applications.  The Company's HiRel segment has a legacy of more than thirty years of experience in many of these market segments, has developed strategic relationships with major system integrators worldwide and has the knowledge, technology and processes required to meet the requirements of customers in the high-reliability markets.  Key products of the HiRel segment include RAD-Hard discretes, RAD-Hard ICs, power management modules and DC-DC converters.

Intellectual Property ("IP") - The IP segment includes revenues from the sale and/or licensing of the Company's technologies and manufacturing process know-how, in addition to the operating results of the Company's patent licensing and settlements of claims brought against third parties.  The Company from time to time enters into opportunistic sale and/or licensing arrangements that it believes are consistent with its business strategy.

12. Segment Information (Continued)

The Company does not allocate assets, sales and marketing, information systems, finance and administrative costs and asset impairment, restructuring and other charges to the operating segments, as these are not meaningful statistics to the CEO in making resource allocation decisions or in evaluating performance of the operating segments.  Because operating segments are generally defined by the products they design and sell, they do not make sales to each other.

The Company does not directly allocate assets to its operating segments, nor does the CEO evaluate operating segments using discrete asset information.  However, depreciation and amortization related to the manufacturing of goods is included in gross profit for the segments as part of manufacturing overhead.  Due to the Company's methodology for cost build up at the product level, it is impractical to determine the amount of depreciation and amortization included in each segment's gross profit.

The Company's "Customer Segments" includes PMD, ESP, AP, EP and HiRel reporting segments.

For the three and nine months ended March 24, 2013 and March 25, 2012, revenues and gross margin by reportable segments were as follows (in thousands, except percentages):

Goodwill

The Company evaluates the carrying value of goodwill and other intangible assets annually during the fourth quarter of each fiscal year and more frequently if it believes indicators of impairment exist.  In evaluating goodwill, a two-step goodwill impairment test is applied to each reporting unit.  The Company identifies reporting units and determines the carrying value of each reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets, to those reporting units.  In the first step of the impairment test, the Company estimates the fair value of the reporting unit.  If the fair value of the reporting unit is less than the carrying value of the reporting unit, the Company performs the second step which compares the implied fair value of the reporting unit with the carrying amount of the reporting unit and writes down the carrying amount of the goodwill to the implied fair value.

The carrying amount of goodwill by reportable segment as of March 24, 2013 and June 24, 2012 was as follows (in thousands):

Income Taxes

13. Income Taxes

The Company recorded a tax expense of $1.6 million or 8.1 percent against a loss of $19.6 million for the three months ended March 24, 2013.   The expense was mainly due to $1.9 million in foreign income taxes, $0.5 million in withholding taxes, and $0.2 million in domestic tax expense.  This expense was partially offset by a reduction in foreign uncertain tax positions, arising from lapses in statutes of limitation of approximately $0.6 million, and the utilization of a $0.4 million state tax credit.

The Company recorded a tax expense of $6.1 million or 8.0 percent against a loss of $76.6 million for the nine months ended March 24, 2013.  This was mainly due to a decrease in the United Kingdom ("U.K.") statutory tax rates, which reduced the value of the Company's net deferred tax assets in the U.K. by $3.2 million, expenses related to foreign income taxes of $4.6 million, foreign withholding taxes of $2.0 million, and domestic tax expense of $1.4 million.  The expense was partially offset by the benefit of $4.7 million arising from reduction in uncertain tax positions during the second and third quarters, and the utilization of a $0.4 million state tax credit.

The Company recorded a tax benefit of $4.5 million or 64.5 percent against a loss of $7.0 million for the three months ended March 25, 2012, and an expense of $2.8 million or 17.8 percent against income of $15.9 million for the nine months ended March 25, 2012.  For the three months ended March 25, 2012, the Company recorded a tax benefit of $4.5 million due to a valuation allowance release of $7.8 million related to deferred tax assets in the U.K., $3.1 million related to deferred tax assets in the U.S., a tax benefit of $1.6 million from an unrealized gain which was partially offset by $3.5 million in withholding taxes, $2.3 million in foreign taxes, $1.8 million of deferred charges, and $0.6 million increase in uncertain tax positions.  For the  nine months ended March 25, 2012, the Company recorded a tax expense of $2.8 million due to foreign taxes of $7.3 million, withholding taxes of $3.5 million, deferred charges of $1.8 million, an increase in uncertain tax positions of $1.4 million, tax rate changes that decreased the Company's deferred tax assets by $0.6 million, and $0.6 million in domestic tax expense which was partially offset by the release of $10.9 million of valuation allowances and a $1.6 million benefit from an unrealized gain.

The Company evaluates its net deferred income tax assets quarterly to determine if valuation allowances are required.  Based on the consideration of all available evidence using a "more-likely-than-not" standard, the Company determined that the valuation allowance established against its federal and California deferred tax assets in the U.S. should remain in place through fiscal year 2013.  These valuation allowances relate to beginning of fiscal year 2013 balances of reserves that were established during fiscal year 2009.  

The Company operates in multiple foreign jurisdictions with lower statutory tax rates, and its operations in Singapore generally have the most significant impact on the Company's effective tax rate. During fiscal year 2011, the Company was granted certain incentives by the Singapore Economic Development Board.  As a result, the Company operates under a tax holiday in Singapore, effective from December 27, 2010 through December 26, 2020.  The tax holiday is conditioned upon the Company meeting certain employment and investment thresholds which have been met to date.  The Company has not realized a benefit for this reporting period.

During the three months ended March 24, 2013, the reserve for uncertain tax positions increased by $1.6 million to $45.1 million.  This increase resulted primarily from a $3.0 million increase to reserves associated with domestic uncertain tax positions.  The increase was offset by an expiration of statute of limitations of $0.6 million and $0.8 million from changes in currency exchange rates related to prior year uncertain tax positions in certain foreign jurisdictions.  For fiscal year 2013, the benefits associated with uncertain tax positions would result in a benefit to income taxes on the consolidated statement of operations of $13.2 million, and if recognized, would reduce the Company's future effective tax rate.  The reserve is expected to decrease by $7.5 million during the next 12 months primarily due to a lapse in the statute of limitations in certain foreign jurisdictions.

As of March 24, 2013, the Company's accrual of interest and penalties related to uncertain tax positions was $4.0 million.  For the three months ended March 24, 2013, penalties and interest included in the reserves decreased by $0.3 million.

While it is often difficult to predict the final outcome or the timing of the resolution of any particular uncertain tax position, the Company believes its reserve for income taxes represents the most probable outcome. The Company adjusts this reserve, including the portion related to interest, in light of changing facts and circumstances.

As of June 24, 2012, U.S. income taxes have not been provided on approximately $95.3 million of undistributed earnings of foreign subsidiaries since those earnings are considered to be invested indefinitely. Determination of the amount of unrecognized deferred tax liabilities for temporary differences related to investments in these non-U.S. subsidiaries that are essentially permanent in duration is not practicable.  

13. Income Taxes (Continued)

Pursuant to Sections 382 and 383 of the U.S. Internal Revenue Code, the utilization of net operating losses ("NOLs") and other tax attributes may be subject to substantial limitations if certain ownership changes occur during a three-year testing period (as defined). The Company does not believe an ownership change has occurred that would limit the Company's utilization of any NOL, credit carry forward or other tax attributes.

On October 25, 2012 (the "Closing Date"), the Company entered into a Credit Agreement (the "Credit Agreement"), as borrower, with Wells Fargo Bank, National Association, as Administrative Agent ("Agent"), and certain lenders (the "Lenders"), pursuant to which it established a new senior unsecured revolving credit facility (the "Facility") in an aggregate principal amount of $100 million with sublimits for swingline loans (of $25 million) and the issuance of letters of credit (of $10 million).  The Credit Facility matures on October 25, 2016.  The proceeds of the Credit Facility may be used by the Company to finance certain capital expenditures and acquisitions permitted thereunder, to provide for the working capital and general corporate needs as well as to pay fees, commissions and expenses associated with the Credit Facility.

The terms of the Credit Agreement require the Company to comply with certain financial tests, and include various affirmative and negative covenants, and customary representations and warranties, conditions and events of default.  Additionally, the Credit Facility is subject to a commitment fee on the unused portion at an initial rate equal to 0.25 percent per annum.  As of March 24, 2013, the Company was in compliance with the financial tests and covenants, and there were no amounts outstanding under the Credit Facility.

Bank Letters of Credit

At March 24, 2013, the Company had $0.7 million of outstanding letters of credit.  These letters of credit are secured by cash collateral provided by the Company equal to their face amount.

Warranty

The Company records warranty liabilities at the time of sale for the estimated costs that may be incurred under the terms of its warranty agreements.  The specific warranty terms and conditions vary depending upon the product sold and the country in which the Company does business.  In general, for standard products, the Company will replace defective parts not meeting the Company's published specifications at no cost to the customers.  Factors that affect the liability include historical and anticipated failure rates of products sold, and cost per claim to satisfy the warranty obligation.  If actual results differ from the estimates, the Company revises its estimated warranty liability to reflect such changes.

Stock-Based Compensation [Abstract]

Stock-Based Compensation

10. Stock‑Based Compensation

The Company issues new shares to fulfill the obligations under all of its stock‑based compensation awards.  Such shares are subject to registration under applicable securities laws, including the rules and regulations promulgated by the Securities and Exchange Commission, unless an applicable exemption applies.

During the nine months ended March 24, 2013, the Company granted an aggregate of 111,000 stock options to Company employees under its 2011 Performance Incentive Plan (the "2011 Plan").  Subject to the terms and conditions of the 2011 Plan and applicable award documentation, such awards generally vest and become exercisable in equal installments over each of the first three anniversaries of the date of grant, with a maximum award term of five years.

The following table summarizes the stock option activities for the nine months ended March 24, 2013 (in thousands, except per share price data):

	Stock Option Shares			Weighted AverageOption ExercisePrice per Share		Weighted AverageGrant DateFair Value per Share		AggregateIntrinsic Value

For the nine months ended March 24, 2013 and March 25, 2012, the Company received $4.3 million and $2.4 million, respectively, for stock options exercised.  There were no tax benefits realized from issuance of stock-based awards for the three and nine months ended March 24, 2013 and March 25, 2012, respectively.

During the nine months ended March 24, 2013, the Company granted 48,300 restricted stock units ("RSUs") to employees, and 61,227 RSUs to members of the Board of Directors, in each case under the 2011 Plan.  The awards provided for vesting over a period of service, subject to the terms and conditions of the 2011 Plan and applicable award documentation.  For the awards made to employees, the vesting of awards generally takes place in equal installments over each of the first three anniversaries of the date of grant.  The awards made to members of the Board of Directors were made as part of the Board's annual director compensation program, under which the vesting of awards takes place generally on the first anniversary of the date of grant.

The following table summarizes the RSU activity for the nine months ended March 24, 2013 (in thousands, except per share price data):

During the nine months ended March 25, 2012, and included in the above table, the Company recorded a net credit of $1.3 million to stock compensation expense relating to performance based awards, based on the determination that the achievement of certain of the performance goals that the Company in the prior year had determined were probable to be achieved were no longer considered probable.

The total unrecognized compensation expense for outstanding stock options and RSUs was $28.5 million as of March 24, 2013.  The unrecognized compensation expense for the outstanding stock options and RSUs will generally be recognized over three years.  The weighted average number of years to recognize the total compensation expense for stock options and RSUs are 2.4 years and 1.8 years, respectively.  As of March 24, 2013, the Company had no RSUs with performance (non-market) based vesting conditions outstanding.

The fair value of the Company stock options issued during the nine months ended March 24, 2013 and March 25, 2012, was determined at the grant date using the Black‑Scholes option pricing model with the following weighted average assumptions:

Environmental Matters

15. Environmental Matters

Federal, state, local and foreign laws and regulations impose various restrictions and controls on the storage, use and discharge of certain materials, chemicals and gases used in semiconductor manufacturing processes, and on the operation of the Company's facilities and equipment. The Company believes it uses reasonable efforts to maintain a system of compliance and controls for these laws and regulations. Despite its efforts and controls, from time to time, issues may arise with respect to these matters. Additionally, under some of these laws and regulations, the Company could be held financially responsible for remedial measures if properties are contaminated or if waste is sent to a landfill or recycling facility that becomes contaminated. Also, the Company may be subject to common law claims if released substances damage or harm third parties. The Company cannot make assurances that changes in environmental laws and regulations will not require additional investments in capital equipment and the implementation of additional compliance programs in the future, which could have a material adverse effect on the Company's results of operations, financial position or cash flows, as could any failure by or violation of the Company to comply with any prior, current or future environmental laws and regulations.

In February 2012, the Company notified the California Department of Toxic Substances Control ("DTSC") and local districts that the Company's Temecula California manufacturing facility previously shipped wastes for disposal offsite as non-hazardous wastes which may have contained fluoride levels that are considered to constitute hazardous waste under California regulations.  The Company has taken steps to ensure compliance with the applicable waste disposal regulations in this regard.  The Company has received a notice of minor administrative violation from one of the local districts requiring updated permit documentation without the assessment of any penalty.  The Company has not as yet been contacted by all applicable regulatory authorities, including the DTSC,  in respect of this matter and it is too early to assess what, if any, penalties or other actions may be taken in the future in respect of the matter.

In December 2010, the owner by foreclosure of a property in El Segundo, California formerly owned and leased by the Company notified the Company of its claim that the Company is a potentially responsible party for the remediation of hazardous materials allegedly discovered by that owner at the property.  The Company had also been contacted by the California Department of Toxic Substances Control in connection with that 2010 notice.  Separately, in July 2012, the Company received notice from a subsequent owner of that property seeking reimbursement of investigation costs and increased construction costs allegedly resulting from the presence of hazardous materials at the property.  The Company intends to vigorously defend against all of the claims asserted by the various parties in respect of the property.

During negotiations for the Company's April 2007 divestiture of the Company's Power Control Systems business to Vishay Intertechnology, Inc., certain chemical compounds were discovered in the groundwater underneath one of the Company's former manufacturing plants in Italy, and the Company advised appropriate governmental authorities at about the time of such divestiture.  In August 2010, the Company received a letter from the relevant local authority requiring a confirmation of intention to proceed with preparation of a plan of characterization in relation to the site in question.  The Company has restated to local authorities its prior position from the period following such divestiture that it had not committed to take further action with respect to the site. In October 2012, local authorities contacted the current site owner suggesting that additional groundwater testing should take place and testing was conducted prior to the close of calendar year 2012.  The Company has not been assessed any penalties with respect to the site, and it is too early to assess whether any such penalties will be assessed or other regulatory actions may be taken in the future.

15. Environmental Matters (Continued)

In November 2007, the Company was named as one of approximately 100 defendants in Angeles Chemical Company, Inc. et al. v. Omega Chemical PRP Group, LLC et al., No. EDCV07-1471 (TJH) (JWJx) (C.D. Cal.) (the "Angeles Case"). Angeles Chemical Company, Inc. and related entities ("Plaintiffs") own or operate a facility (the "Angeles Facility") which is located approximately one and a half miles down gradient of the Omega Chemical Superfund Site (the "Omega Site") in Whittier, California. Numerous parties, including the Company, allegedly disposed of wastes at the Omega Site. Plaintiffs claim that contaminants from the Omega Site migrated in groundwater from the Omega Site to the Angeles Facility, thereby causing damage to the Angeles Facility. In addition, they claim that the EPA considers them to be responsible for the groundwater plume near the Angeles Facility, which Plaintiffs contend was caused by disposal activities at the Omega Site. Plaintiffs filed claims based on the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), nuisance and trespass, and also seek declaratory relief. Plaintiffs seek to require the defendants to investigate and clean-up the contamination and to recover damages. The case has been stayed by the court pending the Environmental Protection Agency's completion of its remedial investigation. The Company previously entered into a settlement with other parties associated with the Omega Site pursuant to which the Company paid those entities money in exchange for an agreement to defend and indemnify the Company with regard to certain environmental claims (the "Omega Indemnification"). In that agreement, it was estimated that the Company's volumetric share of wastes sent to the Omega Site was in the range of 0.08 percent. The Company believes that much, if not all, of the risks associated with the Angeles Case should be covered by the Omega Indemnification. In addition, the Company has tendered the complaint to several of its insurance carriers, one of which has agreed to defend under a reservation of rights. Therefore, the Company does not expect its out-of-pocket defense costs to be significant. In addition, in light of the Omega Indemnification, the potential for insurance coverage and the fact that its volumetric share of Omega Site wastes was less than 0.1 percent, the Company does not believe that an adverse judgment against the Company would be material.

IR and Rachelle Laboratories, Inc. ("Rachelle"), a subsidiary of the Company that discontinued operations in 1986, were each named a potentially responsible party ("PRP") in connection with the investigation by the United States Environmental Protection Agency ("EPA") of the disposal of allegedly hazardous substances at a major superfund site in Monterey Park, California ("OII Site"). Certain PRPs who settled certain claims with the EPA under consent decrees filed suit in Federal Court in May 1992 against a number of other PRPs, including IR, for cost recovery and contribution under the provisions of the CERCLA. The Company has settled all outstanding claims that have arisen against IR relating to the OII Site. No claims against Rachelle have been settled. The Company has taken the position that none of the wastes generated by Rachelle were hazardous.

Counsel for Rachelle received a letter dated August 2001 from the U.S. Department of Justice, directed to all or substantially all PRPs for the OII Site, offering to settle claims against such parties for all work performed through and including the final remedy for the OII Site. The offer required a payment from Rachelle in the amount of approximately $9.3 million in order to take advantage of the settlement. Rachelle did not accept the offer.

It remains the position of Rachelle that its wastes were not hazardous.  In addition, Rachelle operated as an independent corporation and the Company did not believe that a complaining party would be successful in reaching the assets of IR even if it could prevail on a claim against Rachelle.  Because Rachelle has not been sued, none of the Company's insurers has accepted liability, although at least one of the Company's insurers previously reimbursed IR for defense costs for the lawsuit filed against IR.

The Company received a letter in June 2001 from a law firm representing UDT Sensors, Inc. ("UDT") relating to environmental contamination (chlorinated solvents such as trichlorethene) purportedly found in UDT's properties in Hawthorne, California.  The letter alleges that the Company operated a manufacturing business at that location in the 1970's and/or 1980's and that it may have liability in connection with the claimed contamination.  The Company has made no accrual for any potential losses since there has been no assertion of specific facts on which to form the basis for determination of liability.

Site Contingency	In December 2010, the owner by foreclosure of a property in El Segundo, California formerly owned and leased by the Company notified the Company of its claim that the Company is a potentially responsible party for the remediation of hazardous materials allegedly discovered by that owner at the property. The Company had also been contacted by the California Department of Toxic Substances Control in connection with that 2010 notice. Separately, in July 2012, the Company received notice from a subsequent owner of that property seeking reimbursement of investigation costs and increased construction costs allegedly resulting from the presence of hazardous materials at the property. The Company intends to vigorously defend against all of the claims asserted by the various parties in respect of the property.

Net Income per Common Share

Net income (loss) per common share [Abstract]

Net Income per Common Share

14. Net Income per Common Share

The Company calculates earnings per share using the two-class method.  The two-class method requires allocating the Company's net income to both common shares and participating securities.  The Company's participating securities include the unvested, outstanding RSUs to the extent the RSUs provide for the right to receive dividend equivalents.

The following table provides a reconciliation of the numerator and denominator of the basic and diluted per-share computations for the three and nine months ended March 24, 2013 and March 25, 2012 (in thousands, except per share amounts):

	Three Months Ended						Nine Months Ended

Net income (loss) per common share-dilutive	$	(0.31	)	$	(0.04	)	$	(1.20	)	$	0.19

For the three and nine months ended March 24, 2013, 1.2 million shares and 2.2 million shares of common stock equivalents, respectively, were antidilutive and were not included in the computation of diluted earnings per share for these periods.  Additionally, for the three and nine months ended March 25, 2012, 0.9 million shares and 0.3 million shares of common stock equivalents, respectively, were antidilutive and were not included in the computation of diluted earnings per share for these periods.  In addition, for the three and nine months ended March 24, 2013, 0.8 million shares and 0.8 million shares, respectively, of contingently issuable restricted stock units for which all necessary conditions had not been met were not included in the computation of diluted earnings per share.
