NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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.

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 and automotive products.

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 September 2012 and 2011 consisted of 13 weeks ending on September 23, 2012 and September 25, 2011, respectively.

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 of Financial Instruments

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 or not the inputs are observable in the market and the degree that 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 September 23, 2012 and June 24, 2012 (in thousands):

	As of September 23, 2012

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

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 three months ended September 23, 2012, and September 25, 2011, the Company had no significant measurements of assets or liabilities at fair value on a nonrecurring basis.

During the three months ended September 23, 2012 and September 25, 2011, 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) and those valued using significant other observable inputs (Level 2).  The Company determines at the end of the reporting period whether a given financial asset or liability is valued using Level 1, Level 2 or Level 3 inputs.

As of September 23, 2012, the Company's investments recorded at fair value using Level 2 inputs included commercial paper, 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.

Level 3 Valuation Techniques

The following tables provide a reconciliation of the beginning and ending balance of items measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months ended September 23, 2012 and September 25, 2011 (in thousands):

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 are also used to value investment securities that included certain asset-backed securities 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 well as consideration of the volatilities of public companies deemed comparable.  As of September 23, 2012, 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.

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").

  In December 2011, the FASB issued ASC update No. 2011-12, "Comprehensive Income (Topic 220), Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05".  This update defers the requirement in ASC 2011-05 that companies present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income on the face of the financial statements.  A company will continue to be required to present amounts reclassified out of accumulated other comprehensive income on the face of the financial statements or disclose those amounts in the notes to the financial statements.  During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income.  All other requirements in ASC 2011-05 are not affected by this update, including the requirement to report items of net income, other comprehensive income and total comprehensive income in a single continuous or two consecutive statements.  The amendments in this update did not have a material impact on the Company's financial statements.

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.

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 other income or interest income depending upon the type of security.

Available-for-sale securities as of September 23, 2012 are summarized as follows (in thousands):

	Amortized Costs		Gross Unrealized Gain		Gross Unrealized Loss			Net Unrealized Gain		Market Value

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 maximizing the returns on the investment portfolio.

In addition, the Company has a note receivable from a privately held company which it carries at cost of $0.4 million.  This investment is carried at cost as the Company has determined that it is not practicable to estimate the fair value of the investment given that the issuer is a start-up company whose securities are not publicly traded.  As of September 23, 2012, there have been no developments which would indicate the note receivable from that privately held company has been impaired.

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 September 23, 2012, the fair value of the Put Option was $2.9 million, with changes in fair value recorded in other (income)/expense, net (See Note 3, "Derivative Financial Instruments").  Dividend income from these investments was $0.1 million for the three months ended September 23, 2012.  The Company received no dividend income from these equity investments during the three months ended September 25, 2011.

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.

As of September 23, 2012, the Company evaluated whether an equity security with gross unrealized losses of $0.8 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 investment 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 Company may decide to dispose of securities prior to the contractual maturity date indicated in the table above.

During the three months ended September 23, 2012, there were no sales of available-for-sale securities.  During the three months ended September 25, 2011, available-for-sale securities were sold for total proceeds of $5.3 million.  Gross realized gains and (losses) were $0.1 million and $0 million, respectively, for the three months ended September 25, 2011.

During the three months ended September 23, 2012, the Company did not reclassify realized gains (losses) from accumulated other comprehensive income to earnings, as there were no sales for available-for-sale securities.  For the three months ended September 25, 2011, as a result of sales of available-for-sale securities and recognition of other-than-temporary impairments on available-for-sale securities, the Company reclassified $0.1 million from accumulated other comprehensive income to earnings as a component of interest income.

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.  In prior periods, the Company has designated certain derivatives as fair value hedges or cash flow hedges qualifying for hedge accounting treatment.  However, as of September 23, 2012, 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 September 23, 2012.

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 $92.1 million in notional amounts of currency forward contracts not designated as accounting hedges at September 23, 2012.  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 $(2.4) million and $0.8 million for the three months ended September 23, 2012 and September 25, 2011, respectively.

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 September 23, 2012 and June 24, 2012 was as follows (in thousands):

Business Segments:	September 23, 2012		June 24, 2012

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.

10. Stock-Based Compensation (Continued)

The total unrecognized compensation expense for outstanding stock options and RSUs was $38.4 million as of September 23, 2012.  The unrecognized compensation expense for the outstanding stock options and RSUs will generally be recognized over three years, except for one stock option award and one RSU award made to the Chief Executive Officer (the "CEO") during fiscal year 2008.  The compensation expense for the CEO's awards made during fiscal year 2008 is being recognized over 5 years.  The weighted average number of years to recognize the total compensation expense (including that of the CEO) for stock options and RSUs are 0.9 years and 2.2 years, respectively.  As of September 23, 2012, the Company had no RSUs with performance (non-market) based vesting conditions outstanding.

The fair value of the Company stock options issued during the three months ended September 23, 2012 and September 25, 2011, was determined at the grant date using the Black‑Scholes option pricing model with the following weighted average assumptions:

	Three Months Ended
	September 23, 2012	September 25, 2011
Expected life	3.5 years	3.5 years
Risk free interest rate	0.4%	0.4%
Volatility	39.4%	49.6%
Dividend yield	0.0%	0.0%

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 were expensed during the period in which all requirements of recognition were 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 with estimated total pre-tax costs of $9.0 million.  These consist of $5.7 million of severance and workforce reduction costs, $2.1 million of decommissioning costs, and $1.2 million of relocation and re-qualification costs.  The restructuring charge recorded during the three months ended September 23, 2012 included $5.7 million of severance costs and workforce reduction costs.  In addition, during the three months ended September 23, 2012, the Company recorded $0.9 million of other charges related to the restructuring initiative in cost of sales that affected the ESP reporting segment.  These other charges, which were for accelerated depreciation and inventory write-downs, are not classifiable as restructuring costs, and were therefore recorded in cost of sales.

During the first quarter of fiscal year 2013, cash payments for this initiative were $0.8 million and are estimated to be approximately $6.2 million and $2.0 million for the remainder of fiscal year 2013 and thereafter, respectively.

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 with estimated total pre-tax costs of approximately $13 million.  These consist of approximately $2 million of severance and workforce reduction costs, $5 million of decommissioning costs, and $6 million of relocation and re-qualification costs.  These charges will not impact any specific reporting segment.

Cash payments for this initiative are estimated to be approximately $4 million during fiscal year 2013, and $9 million thereafter.

Fiscal Year 2013 Other Cost Reduction Activities Initiative

During the first quarter 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 estimates that it will incur approximately $4.2 million of severance and other workforce reduction costs by the end of fiscal year 2013.  In connection with that effort, during the three months ended September 23, 2012, the Company incurred approximately $3.3 million of severance and workforce reduction costs.  The severance and workforce reduction costs recorded during the three months ended September 23, 2012 included $2.1 million related to other manufacturing facilities in Mexico, California, and Arizona, and $1.2 million for administrative and research and development functions around the world.

The Company continues to review its manufacturing footprint and identify additional cost reduction opportunities, and the nature, timing and extent of the Company's restructuring activities are not yet complete.  Accordingly, and as part of those ongoing efforts, the Company may also incur asset write-downs related to the ultimate disposition of certain manufacturing equipment; any such potential future asset write-downs do not meet the criteria under GAAP to be accrued at this time.

During the first quarter of fiscal year 2013, cash payments for this initiative were $1.9 million and are estimated to be approximately $2.3 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 months ended September 23, 2012 and September 25, 2011, revenues and gross margin by reportable segments were as follows (in thousands, except percentages):

	Three Months Ended
	September 23, 2012								September 25, 2011

13. Income Taxes

The Company's effective tax rate was a tax expense of 31.8 percent against a loss of $21.8 million and a tax expense of 22.2 percent against a profit of $28.2 million for the three months ended September 23, 2012 and September 25, 2011 respectively.  For the three months ended September 23, 2012, the Company's provision for taxes was not comparable to the United States ("U.S.") federal statutory rate of 35 percent.  The main components of the tax provision were a reduction in the U.K. statutory tax rates, reducing the value of the Company's net deferred tax assets in the U.K. by $3.2 million, a $2.2 million expense related to foreign income taxes, foreign withholding taxes, and no tax benefit from the ordinary loss in the U.S. due to the Company's valuation allowance position which were partially offset by benefitting a loss in a foreign jurisdiction.

During the three months ended September 23, 2012, the statutory tax rate in the U.K. was reduced from 25 percent to 24 percent, effective April 1, 2012, and further reduced to 23 percent effective April 1, 2013.  The Company reported a $3.2 million one-time expense due to the rate reduction on the deferred tax assets in the U.K. as a discrete item in the provision for income taxes.

For the three months ended September 25, 2011, the effective rate was lower than the U.S. federal statutory rate of 35 percent primarily due to the utilization of our deferred tax assets through a reduction of the beginning-of-the-year valuation allowance recorded in the U.K. and lower tax rates in certain foreign jurisdictions, and the impact on the tax provision due to the reduction of the U.K. statutory rate.

13. Income Taxes (Continued)

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 the year balances of reserves that were established during fiscal year 2009.  During fiscal year 2012, the Company had released a remaining $28.6 million valuation allowance established against its deferred tax assets in the United Kingdom ("U.K.") as a result of cumulative pretax income generated by our U.K. subsidiary.

During fiscal years 2011 and 2012, the Company recorded deferred charges and valuation allowances related to certain intercompany transactions which reduced the respective deferred tax assets and associated valuation allowances in the U.K. and U.S.   Due to quarterly amortization of the deferred charge and valuation allowance for the three months ended September 23, 2012, these U.K. items were reduced by $0.7 million and $0.3 million, respectively, with the rest of them being an expense within the tax provision.  As a result of quarterly amortization of the deferred charge and valuation allowance for the three months ended September 23, 2012, these U.S. items were reduced by $0.5 million and $0.4 million, respectively, with the rest of them being an expense within the tax provision.

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.

During the three months ended September 23, 2012, the reserve for uncertain tax positions increased by $0.8 million to $49.7 million.  This increase resulted primarily from changes in currency exchange rates related to prior year uncertain tax positions in certain foreign jurisdictions and additional reserves for state credits accrued during the three months ended September 23, 2012.  For fiscal year 2013, $0.1 million of increases to uncertain tax positions, if recognized, would affect the effective tax rate. The reserve is expected to decrease by $4.4 million during the next 12 months.

As of September 23, 2012, the Company had accrued $3.2 million of interest and penalties related to uncertain tax positions.  For the three months ended September 23, 2012, penalties and interest included in the reserves increased by $0.1 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.  The Company has not recorded a deferred tax liability on any potential gain as the earnings and profits of the subsidiary had been recognized as U.S. income in previous periods.

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.

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 months ended September 23, 2012 and September 25, 2011 (in thousands, except per share amounts):

	Three Months Ended

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 a plan of groundwater monitoring should be undertaken.  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.

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 for the claims that remain unresolved by the Court's summary adjudication determination, 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 September 23, 2012, the balance of the divested entities tax obligations was $2.0 million.

18. Stock Repurchase Program

The Company's stock repurchase program authorizes it to repurchase up to $150.0 million.  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 three months ended September 23, 2012, 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.  As of September 23, 2012, the Company had not cancelled the repurchased shares of common stock, and as such, they are reflected as treasury stock in the September 23, 2012 and June 24, 2012 consolidated condensed balance sheets.

19. Subsequent Events

On October 25, 2012, the Company entered into a credit agreement with certain lenders, among them Wells Fargo Bank, National Association, pursuant to which the Company established a new senior unsecured revolving credit facility (the "Credit Facility") in an aggregate principal amount of $100 million (with sub-limits for swingline loans and the issuance of letters of credit), which will mature 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, and to provide for the working capital and general corporate needs of the Company.  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.

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 months ended September 23, 2012.  The discussion includes:

· Overview

· Results of Operations

· Liquidity and Capital Resources

· Critical Accounting Policies

Overview

Our revenues were $252.5 million and $302.7 million for the three months ended September 23, 2012 and September 25, 2011, respectively, a decrease of 16.6 percent in the current quarter.  We experienced a sharp decline in demand for our products during fiscal year 2012, and we have not seen a recovery in demand during the three months ended September 23, 2012, with a sequential decrease in revenue of 6.4 percent compared to the three months ended June 24, 2012.  We currently expect revenues for the next fiscal quarter to range between $215 million and $230 million.

Our gross margin percentage declined by 10.0 percentage points to 27.9 percent for the three months ended September 23, 2012, compared to the three months ended September 25, 2011, and increased by 2.0 percentage points compared to the three months ended June 24, 2012.  The decrease in gross margin percentage compared to the three months ended September 25, 2011 was 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. The increase in the gross margin percentage compared to the three months ended June 24, 2012 was due to certain impairment costs that affected that quarter, an improved product mix due to an increase in HiRel sales as a percentage of our total sales, and decreased inventory write-downs, partially offset by a decrease in factory utilization.  As a result of decreased customer demand, we expect our gross margin for the next fiscal quarter to be between 22 percent and 23 percent.

During the three months ended September 23, 2012, we took a number of actions to respond to a decrease in customer demand, including initiatives to adjust our internal manufacturing footprint and reduce costs.  We also continued our existing efforts to increase our manufacturing flexibility by qualifying new 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.

34

During the three months ended September 23, 2012, we adopted a restructuring plan to modify our manufacturing strategy and lower our operating expenses in order to align our cost structure with current business conditions.  As part of the plan, we intend to close our El Segundo wafer fabrication facility, resize our Newport, Wales wafer fabrication facility and take other cost reduction actions.  We plan to complete the closure of our El Segundo wafer fabrication facility by the end of March 2013 with estimated annual cost savings of approximately $10 million following completion.  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.  During the three months ended September 23, 2012, we also reduced our cost of goods sold, selling, general and administrative costs and research and development costs through headcount reductions, and there are additional reductions planned for the second quarter.  When complete, this headcount reduction initiative is expected to generate $13 million of annual cost savings.  In conjunction with the above plans, we incurred approximately $9.0 million of severance and related costs during the three months ended September 23, 2012.  Additionally, we anticipate that we will incur asset impairment, restructuring and other charges during the remainder of fiscal year 2013 of approximately $6.3 million (See Part I, Item 1, Notes to Consolidated Financial Statements- Note 11, "Asset Impairment, Restructuring and Other Charges").

During the three months ended September 23, 2012, our selling, general and administrative ("SG&A") expenses decreased $4.0 million compared to the three months ended June 24, 2012 and decreased $1.7 million compared to the three months ended September 25, 2011.  As a percentage of revenues, SG&A expense was 18.7 percent of revenue, down 0.3 percentage points compared to the three months ended June 24, 2012 and up 2.5 percentage points compared to the three months ended September 25, 2011.  The year-over-year decrease in SG&A expenses was primarily due to a decrease in headcount related expenses, including incentive bonus, offset by depreciation related to our Enterprise Resource Planning ("ERP") system, higher legal costs, and increased stock compensation expense.  The sequential decrease in SG&A expenses was primarily due to decreases in severance, professional services, and salaries, offset by higher stock compensation expense, commissions, and legal costs.We expect our SG&A expenses to be reduced to approximately $45 million in the second quarter of fiscal year 2013 as a result of operational efficiencies we have achieved from the ERP implementation.

During the three months ended September 23, 2012, research and development ("R&D") spending decreased by $1.6 million compared to the three months ended June 24, 2012 and increased by $0.4 million compared to the three months ended September 25, 2011.  As a percentage of revenues, R&D expense increased from 13.0 percent for the three months ended June 24, 2012 and 10.9 percent for the three months ended September 25, 2011 to 13.2 percent for the three months ended September 23, 2012.  The year-over-year increase in R&D expenses was primarily a result of increased material costs and higher salary and stock compensation expense, offset by a decrease in incentive bonus.  The sequential decrease in R&D expenses was primarily driven by decreased headcount, lower material costs, and less travel expense.  We expect to reduce spending levels for new product development over the next year as part of our cost reduction initiatives.

Our cash flows from operating activities provided $6.5 million of cash during the first three months of fiscal year 2013 compared to $16.6 million for prior year comparable period.  Our cash, cash equivalents and investments as of September 23, 2012 totaled $365.6 million (excluding restricted cash of $1.6 million), compared to $384.3 million (excluding restricted cash of $1.5 million) as of June 24, 2012.  The decrease in our cash and investments was primarily due to our operating loss during the first quarter of fiscal year 2013.

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 ongoing customer segments, 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 ongoing customer segment, HiRel.  For ease of reference, we refer to these four segments collectively as our "Commercial Segments."  What we refer to as our "ongoing customer segments" include our PMD, ESP, AP, EP and HiRel reporting segments, and what we refer to as our "ongoing segments" include the ongoing customer segments as well as the IP reporting segment.

Revenues

Revenues from all our segments, taken as a whole, decreased by $50.2 million, or 16.6 percent, while revenues from our customer segments (which excludes the IP segment) decreased by $50.6 million, or 16.8 percent, for the three months ended September 23, 2012 as compared to three months ended September 25, 2011.  Revenues for our commercial segments taken as a whole decreased 19.9 percent from prior year comparable period which was near the peak of semiconductor cycle.  Revenues for our HiRel segment decreased 0.9 percent from the prior year comparable period.

36

Within our commercial segments, EP revenue increased 5.1 percent for the three months ended September 23, 2012 as compared to the prior year comparable period.  Revenues for our EP segment increased due to an increase in demand for high performance computing and prior generation server components.   Revenues for our PMD segment decreased 18.3 percent compared to the prior year comparable period due to a decrease in demand for our universal power supply, consumer products, and industrial products components.  Revenues for our ESP segment decreased 41.6 percent due to decreased demand in our industrial and consumer appliance related products.  Revenues for our AP segment remained fairly flat with a slight decrease of 0.2 percent compared to the prior year comparable period.

For the three months ended September 23, 2012, our HiRel segment revenues decreased 0.9 percent compared to the prior year comparable period.  HiRel experienced slight changes in product line mix with most market areas maintaining demand similar to that of the prior year comparable period.

For the three months ended September 23, 2012, our IP segment revenues increased $0.4 million or 21.5 percent, to $2.1 million. The increase in revenue arose from a one-time $1.7 million sale of patents.  We expect our IP segment revenues will return to approximately $0.4 million per quarter in each of the next several quarters.  However, we do intend to continue to seek opportunistic sale and/or licensing opportunities consistent with our business strategy.

Gross Margin

Our gross margin decreased by 10.0 percentage points to 27.9 percent for the three months ended September 23, 2012 compared to the prior year comparable period.  This decrease in our gross margin was the result of a decrease of 13.9 percentage points in gross margin for our commercial segments taken as a whole, and an increase of 3.7 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 EP segment's unfavorable product mix was due to an increase in computing components business, which has lower gross margins than our server business.  Our AP segment's unfavorable product mix was due to a decrease in our IC product demand, which are higher margin products than our MOSFET products.  Our PMD segment's unfavorable change in product mix was due to reduced sales of our industrial products, which have higher gross margins than our consumer components business, as well as price erosion. Our ESP segment's unfavorable product mix was due to a decrease in HVIC demand, which generally are higher margin products than our IGBT products.

HiRel segment's gross margin improved by 3.7 percentage points for the three months ended September 23, 2012 compared to the prior year comparable period due to recognition of high margin revenues related to the space market, a decline in some low margin shipments, and delivery of certain products that carried a lower cost of production versus the comparable prior period.

IP segment's gross margin declined by 30.7 percentage points for the three months ended September 23, 2012 compared to the prior year comparable period due to costs associated with the sale of patents.

Selling, General and Administrative Expense

(Dollars in thousands)	Three Months Ended
	September 23, 2012		% of Revenues			September 25, 2011		% of Revenues			Change
Selling, general and administrative expenses	$	47,295		18.7	%	$	48,991		16.2	%	2.5ppt

Selling, general and administrative expense was $47.3 million (18.7 percent of revenues) and $49.0 million (16.2 percent of revenues) for the three months ended September 23, 2012 and September 25, 2011, respectively. The decrease in selling, general and administrative expense for the three months ended September 23, 2012, compared to the prior year comparable period, was primarily due to a decrease in salaries and incentive bonuses, offset by increased depreciation related to our ERP system, higher legal costs, and increased stock compensation expense.We expect our SG&A expenses to be reduced to approximately $45 million for the second quarter of fiscal year 2013 as a result of operational efficiencies we have achieved from the ERP implementation combined with the implementation of our cost reduction initiatives.

Research and Development Expense

(Dollars in thousands)	Three Months Ended
	September 23, 2012		% of Revenues			September 25, 2011		% of Revenues			Change
Research and Development expense	$	33,449		13.2	%	$	33,028		10.9	%	2.3ppt

Research and development expense was $33.4 million (13.2 percent of revenues) and $33.0 million (10.9 percent of revenues) for the three months ended September 23, 2012 and September 25, 2011, respectively. The increase of $0.4 million in R&D expense for the three months ended September 23, 2012, compared to the prior year comparable period, was primarily a result of increased material costs and higher salary and stock compensation expense, offset by a decrease in incentive bonus.  We expect to decrease spending levels for new product development over the next year as part of our cost reduction initiatives.

Amortization of acquisition-related intangible assets

(Dollars in thousands)	Three Months Ended
	September 23, 2012		% of Revenues			September 25, 2011		% of Revenues			Change
Amortization of acquisition-related intangible assets	$	1,680		0.7	%	$	2,615		0.9	%	(0.2)ppt

Amortization of acquisition-related intangible assets was $1.7 million (0.7 percent of revenues) and $2.6 million (0.9 percent of revenues) for the three months ended September 23, 2012 and September 25, 2011, respectively.  The decrease of $0.9 million for the three months ended September 23, 2012, compared to the prior year period, was 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 were expensed during the period in which all requirements of recognition were 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

38

The following tables summarize the total asset impairment, restructuring and other charges by initiative for the three months ended September 23, 2012 (in thousands):

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 with estimated total pre-tax costs of $9.0 million.  These consist of $5.7 million of severance and workforce reduction costs, $2.1 million of decommissioning costs, and $1.2 million of relocation and re-qualification costs.  The restructuring charge recorded during the three months ended September 23, 2012 included $5.7 million of severance costs and workforce reduction costs.  In addition, during the three months ended September 23, 2012, we recorded $0.9 million of other charges related to the restructuring initiative in cost of sales that affected the ESP reporting segment.  These other charges, which were for accelerated depreciation and inventory write-downs, are not classifiable as restructuring costs, and were therefore recorded in cost of sales.

During the first quarter of fiscal year 2013, cash payments for this initiative were $0.8 million and are estimated to be approximately $6.2 million and $2.0 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.

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 with estimated total pre-tax costs of approximately $13 million.  These consist of approximately $2 million of severance and workforce reduction costs, $5 million of decommissioning costs, and $6 million of relocation and re-qualification costs.  The charges will not impact any specific reporting segment.

Cash payments for this initiative are estimated to be approximately $4 million during fiscal year 2013, and $9 million thereafter. 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.

Fiscal Year 2013 Other Cost Reduction Activities Initiative

During the first quarter 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 estimate that we will incur approximately $4.2 million of severance and other workforce reduction costs by the end of fiscal year 2013.  In connection with that effort, during the three months ended September 23, 2012, we incurred approximately $3.3 million of severance and workforce reduction costs.  The severance and workforce reduction costs recorded during the three months ended September 23, 2012 included $2.1 million related to other manufacturing facilities in Mexico, California, and Arizona, and $1.2 million for administrative and research and development functions around the world.

We continue to review our manufacturing footprint and identify additional cost reduction opportunities, and the nature, timing and extent of our restructuring activities are not yet complete.  Accordingly, and as part of those ongoing efforts, we may also incur asset write-downs related to the ultimate disposition of certain manufacturing equipment; any such potential future asset write-downs do not meet the criteria under GAAP to be accrued at this time.

During the first quarter of fiscal year 2013, cash payments for this initiative were $1.9 million and are estimated to be approximately $2.3 million for the remainder of fiscal year 2013. After the completion of this initiative, we estimate annual cost savings of approximately $13 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, net includes, primarily, gains and losses related to foreign currency fluctuations and investment impairments.  Other expense, net was $1.0 million and $2.2 million for the first three months of fiscal years 2013 and 2012, respectively. Other expense for the three months ended September 23, 2012 includes a foreign currency exchange loss of $1.0 million due to fluctuations in foreign exchange currencies during the quarter.  The prior year comparable period included a foreign exchange loss of $1.7 million due to significant fluctuations in foreign exchange currencies during that prior quarter and an investment impairment charge of $0.5 million.

Interest Income and Expense

Interest income was $0.2 million and $0.3 million for the first three months of fiscal years 2013 and 2012, respectively.

Interest expense was $0.1 million for both the first three months of fiscal years 2013 and 2012, respectively.

Income Taxes

Our effective tax rate was a tax expense of 31.8 percent against a loss of $21.8 million and a tax expense of 22.2 percent against a profit of $28.2 million for the three months ended September 23, 2012 and September 25, 2011 respectively.  For the three months ended September 23, 2012, our provision for taxes was not comparable to the United States ("U.S.") federal statutory rate of 35 percent.  The main components of the tax provision were a reduction in the U.K. statutory tax rates, reducing the value of our net deferred tax assets in the U.K. by $3.2 million, a $2.2 million expense related to foreign income taxes, foreign withholding taxes, and no tax benefit from the ordinary loss in the U.S. due to our valuation allowance position which were partially offset by benefitting a loss in a foreign jurisdiction.

For the three months ended September 25, 2011, our effective rate was lower than the United States ("U.S.") federal statutory rate of 35 percent primarily due to the utilization of our deferred tax assets through the reduction of the beginning-of-the-year valuation allowance recorded in the United Kingdom ("U.K.") and lower tax rates in certain foreign jurisdictions, and the impact on the tax provision due to the reduction of the U.K. statutory rate.  

During the three months ended September 23, 2012, the statutory tax rate in the U.K. was reduced from 25 percent to 24 percent, effective April 1, 2012 and further reduced to 23 percent effective April 1, 2013. We reported the $3.2 million impact of such a rate reduction on the deferred tax assets in the U.K. as a discrete item in the provision for income taxes.

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 for the fiscal year 2012.  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 covenants contained in the revolving credit agreement.

As of September 23, 2012, we had $365.6 million of cash (excluding $1.6 million of restricted cash), cash equivalents and short-term and long-term investments, consisting of available-for-sale fixed income and investment‑grade securities, a decrease of $18.7 million from June 24, 2012.  The decrease in our cash and investments was primarily due to our operating loss during the first quarter of fiscal year 2013.

Total cash, cash equivalents, and investments at September 23, 2012 and June 24, 2012 were as follows (in thousands):

	September 23, 2012		June 24, 2012
Cash and cash equivalents	$	279,815	$	305,423
Investments		85,825		78,926
Total cash, cash equivalents, and investments	$	365,640	$	384,349

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, if any, repurchase of stock for our common stock repurchase program and capital expenditures.  During the first three 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 fiscal year 2013 is that our cash flow from operating activities may be positive or negative depending on whether market conditions become more favorable in the second half of the fiscal year.  We estimate that cash capital equipment expenditures for the fiscal year 2013 will be about $100 million as we invest in new manufacturing process technologies.

Cash Flows

Our cash flows were as follows (in thousands):

	Three Months Ended
	September 23, 2012			September 25, 2011
Cash flows provided by operating activities	$	6,539		$	16,600
Cash flows used in investing activities		(28,851	)		(23,995	)
Cash flows used in financing activities		(5,526	)		(24,356	)
Effect of exchange rate changes on cash and cash equivalents		2,230			(2,441	)
Net decrease in cash and cash equivalents	$	(25,608	)	$	(34,192	)

Non-cash adjustments to cash flow generated by operating activities during the three months ended September 23, 2012 included $22.7 million of depreciation and amortization, $5.7 million of stock compensation expense, and $5.3 million from the gross additions to the inventory provision.  Changes in operating assets and liabilities reduced cash provided by operating activities by $5.1 million, primarily attributed to a decrease in accounts payable and a decrease in other accrued expenses, partially offset by a decrease in trade accounts receivable and a decrease in inventory.

42

Cash used in investing activities during the three months ended September 23, 2012 was primarily the result of capital expenditures of $22.0 million and purchases of investments for $10.0 million, partially offset by proceeds from the sale or maturities of investments of $3.0 million.

Cash used in financing activities during the three months ended September 23, 2012 of $5.5 million was primarily the result of cash used for stock repurchases under the stock repurchase program.

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.

43

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 three months ended September 23, 2012 were as follows (in thousands):

	September 23,		June 24,
	2012		2012		Change
Current Assets
Cash and cash equivalents	$	279,815	$	305,423	$	(25,608	)
Restricted cash		616		595		21
Short-term investments		75,777		63,872		11,905
Trade accounts receivable, net		151,556		168,499		(16,943	)
Inventories		283,516		294,702		(11,186	)
Current deferred tax assets		5,251		5,110		141
Prepaid expenses and other receivables		34,347		29,845		4,502
Total current assets	$	830,878	$	868,046	$	(37,168	)
Current Liabilities
Accounts payable	$	66,342	$	88,726	$	(22,384	)
Accrued income taxes		—		750		(750	)
Accrued salaries, wages and commissions		44,008		40,403		3,605
Other accrued expenses		75,745		83,164		(7,419	)
Total current liabilities		186,095		213,043		(26,948	)
Net working capital	$	644,783	$	655,003	$	(10,220	)

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 $16.9 million reflects the sequential quarter over quarter decrease in revenues of approximately 6.4 percent during the first three months of fiscal year 2013 while our days-sales-outstanding decreased by 2 days.

Inventories decreased $11.2 million including a $19.6 million decrease in finished goods, partially offset by a $0.8 million increase in work-in-process inventory and a $7.6 million increase in raw materials.  Despite this decrease in inventory, inventory weeks increased by 1 week to approximately 20 weeks.

Accounts payable decreased by $22.4 million from year end with decreases related to reduced manufacturing activity, lower capital expenditures, and the timing of payments.

The increase in accrued salaries, wages and commissions of $3.6 million for the first three months of fiscal year 2013 was due primarily to higher accrued salary and payroll taxes due to the timing of the pay period end.

44

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 $3.3 million is more likely than not and as such, we have not recognized them as income tax benefits in our consolidated financial statements.

Contractual Obligations

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

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 September 23, 2012.

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 maximizing returns.  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 September 23, 2012, a 100 basis point increase or decrease in interest rates would result in an annualized change of approximately $0.7 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.

 We had approximately $92.1 million in notional amounts of currency forward contracts not designated as accounting hedges at September 23, 2012.  Net realized and unrealized foreign‑currency gains (losses) related to foreign currency forward contracts recognized in earnings, as a component of other expense, were $(2.4) million and $0.8 million for the three months ended September 23, 2012 and September 25, 2011, 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 September 23, 2012, we had $365.6 million of total cash (excluding $1.6 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 AA+/Aa1.  Our investment policy is to manage our total cash and investment balances to preserve principal and maintain liquidity while maximizing returns.  To the extent that certain investments in our portfolio of investments continue to have strategic value, we generally do not attempt to reduce or eliminate our market exposure.  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.  During the three months ended September 23, 2012, 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 September 23, 2012.  Based upon this evaluation, our CEO and CFO concluded that, as of September 23, 2012, 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 September 23, 2012 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.

PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

Our disclosures regarding the matters set forth in Note 15, "Environmental Matters," and Note 16, "Litigation," to our Notes to the Unaudited Condensed Consolidated Financial Statements set forth in Part I, Item I, herein, are incorporated herein by reference.

ITEM 1A.  RISK FACTORS

Statement of Caution Under the Private Securities Litigation Reform Act of 1995

This Quarterly Report on Form 10-Q includes some statements and other information that are not historical facts but are "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995. The materials presented can be identified by the use of forward‑looking terminology such as "anticipate," "believe," "estimate," "expect," "may," "should," "view," or "will" or the negative or other variations thereof. We caution that such statements are subject to a number of uncertainties, and actual results may differ materially. Factors that could affect our actual results include those set forth under "Item 1A. Risk Factors" in our 2012 Annual Report, as supplemented by other uncertainties disclosed in our reports filed from time to time with the SEC (all of the foregoing of which is incorporated by reference) and the factor set forth below.

We are subject to a revolving credit facility that may restrict our current and future operations

In October 2012, we entered into a four year senior unsecured revolving credit facility which expires in October, 2016 and under which we may borrow up to $100 million. Whether or not we have borrowings under the facility, the revolving credit facility imposes restrictions on us, including restrictions on 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 and other matters customarily restricted in such agreements.  The terms of the credit facility also require us to comply with certain financial tests. 

We cannot assure that we will be able to satisfy the financial tests set forth under the revolving credit facility to be able to make or maintain borrowings under the facility.  Also, whether or not we make borrowings under the facility, restrictions under the facility may limit our ability to engage in activities or transactions that could otherwise benefit us.  If we cannot satisfy the restrictions and financial tests under the revolving credit facility, then we may either have to terminate the facility and repay any indebtedness thereunder or be subject to an event of default that could materially and adversely affect our operating results and our financial condition.

ITEM 5.    OTHER INFORMATION

In Part II, Item 9B, "Other Information" of the 2012 Annual Report, the Company reported that it had announced a restructuring plan to modify the Company's manufacturing strategy and lower its operating expenses in order to align its cost structure with business conditions.

As part of the plan, the Company announced that it planned to close its El Segundo, California wafer fabrication facility, resize its wafer fabrication facility in Newport, Wales and take other cost reduction actions. As of the date of the filing of the 2012 Annual Report, the Company was not able to determine all of the estimated costs and expenditures relating to the plan.

The Company supplements its prior disclosures in respect of (i) the description of the course of action, including the facts and circumstances leading to the expected action and completion date, (ii) an estimate of the total amount or range of amounts expected to be incurred in connection with the action, and similar information in respect of each major type of cost, (iii) an estimate of the amount or range of amounts of the charge that will result in future cash expenditures in respect of the plan, in each case by incorporation of such information herein by reference to the disclosures set forth under the heading "Asset Impairment, Restructuring and Other Charges" in Part 1, Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations set forth earlier in this Quarterly Report on Form 10-Q and subject to the qualifications set forth therein.

Our restructuring program is subject to a number of risks (see Part I, Item 1A, "Risk Factors- Our restructuring programs may not achieve their goals, could be costly, delayed and disruptive to our business, and could materially adversely affect our results and financial condition" set forth in our 2012 Annual Report, as supplemented by other uncertainties disclosed in our reports filed from time to time with the SEC).

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.  In prior periods, the Company has designated certain derivatives as fair value hedges or cash flow hedges qualifying for hedge accounting treatment.  However, as of September 23, 2012, 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 September 23, 2012.

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 $92.1 million in notional amounts of currency forward contracts not designated as accounting hedges at September 23, 2012.  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 $(2.4) million and $0.8 million for the three months ended September 23, 2012 and September 25, 2011, respectively.

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 other income or interest income depending upon the type of security.

Available-for-sale securities as of September 23, 2012 are summarized as follows (in thousands):

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 maximizing the returns on the investment portfolio.

In addition, the Company has a note receivable from a privately held company which it carries at cost of $0.4 million.  This investment is carried at cost as the Company has determined that it is not practicable to estimate the fair value of the investment given that the issuer is a start-up company whose securities are not publicly traded.  As of September 23, 2012, there have been no developments which would indicate the note receivable from that privately held company has been impaired.

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 September 23, 2012, the fair value of the Put Option was $2.9 million, with changes in fair value recorded in other (income)/expense, net (See Note 3, "Derivative Financial Instruments").  Dividend income from these investments was $0.1 million for the three months ended September 23, 2012.  The Company received no dividend income from these equity investments during the three months ended September 25, 2011.

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.

As of September 23, 2012, the Company evaluated whether an equity security with gross unrealized losses of $0.8 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 investment 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 September 23, 2012, by contractual maturity, are as follows (in thousands):

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

During the three months ended September 23, 2012, there were no sales of available-for-sale securities.  During the three months ended September 25, 2011, available-for-sale securities were sold for total proceeds of $5.3 million.  Gross realized gains and (losses) were $0.1 million and $0 million, respectively, for the three months ended September 25, 2011.

During the three months ended September 23, 2012, the Company did not reclassify realized gains (losses) from accumulated other comprehensive income to earnings, as there were no sales for available-for-sale securities.  For the three months ended September 25, 2011, as a result of sales of available-for-sale securities and recognition of other-than-temporary impairments on available-for-sale securities, the Company reclassified $0.1 million from accumulated other comprehensive income to earnings as a component of interest income.

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.

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 for the claims that remain unresolved by the Court's summary adjudication determination, 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.

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.

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 and automotive products.

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 September 2012 and 2011 consisted of 13 weeks ending on September 23, 2012 and September 25, 2011, respectively.

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 of Financial Instruments

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 or not the inputs are observable in the market and the degree that 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 September 23, 2012 and June 24, 2012 (in thousands):

	As of September 23, 2012

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 three months ended September 23, 2012, and September 25, 2011, the Company had no significant measurements of assets or liabilities at fair value on a nonrecurring basis.

During the three months ended September 23, 2012 and September 25, 2011, 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) and those valued using significant other observable inputs (Level 2).  The Company determines at the end of the reporting period whether a given financial asset or liability is valued using Level 1, Level 2 or Level 3 inputs.

As of September 23, 2012, the Company's investments recorded at fair value using Level 2 inputs included commercial paper, 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 are also used to value investment securities that included certain asset-backed securities 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 well as consideration of the volatilities of public companies deemed comparable.  As of September 23, 2012, 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.

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").

  In December 2011, the FASB issued ASC update No. 2011-12, "Comprehensive Income (Topic 220), Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05".  This update defers the requirement in ASC 2011-05 that companies present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income on the face of the financial statements.  A company will continue to be required to present amounts reclassified out of accumulated other comprehensive income on the face of the financial statements or disclose those amounts in the notes to the financial statements.  During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income.  All other requirements in ASC 2011-05 are not affected by this update, including the requirement to report items of net income, other comprehensive income and total comprehensive income in a single continuous or two consecutive statements.  The amendments in this update did not have a material impact on the Company's financial statements.

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.

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 were expensed during the period in which all requirements of recognition were 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 with estimated total pre-tax costs of $9.0 million.  These consist of $5.7 million of severance and workforce reduction costs, $2.1 million of decommissioning costs, and $1.2 million of relocation and re-qualification costs.  The restructuring charge recorded during the three months ended September 23, 2012 included $5.7 million of severance costs and workforce reduction costs.  In addition, during the three months ended September 23, 2012, the Company recorded $0.9 million of other charges related to the restructuring initiative in cost of sales that affected the ESP reporting segment.  These other charges, which were for accelerated depreciation and inventory write-downs, are not classifiable as restructuring costs, and were therefore recorded in cost of sales.

During the first quarter of fiscal year 2013, cash payments for this initiative were $0.8 million and are estimated to be approximately $6.2 million and $2.0 million for the remainder of fiscal year 2013 and thereafter, respectively.

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 with estimated total pre-tax costs of approximately $13 million.  These consist of approximately $2 million of severance and workforce reduction costs, $5 million of decommissioning costs, and $6 million of relocation and re-qualification costs.  These charges will not impact any specific reporting segment.

Cash payments for this initiative are estimated to be approximately $4 million during fiscal year 2013, and $9 million thereafter.

Fiscal Year 2013 Other Cost Reduction Activities Initiative

During the first quarter 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 estimates that it will incur approximately $4.2 million of severance and other workforce reduction costs by the end of fiscal year 2013.  In connection with that effort, during the three months ended September 23, 2012, the Company incurred approximately $3.3 million of severance and workforce reduction costs.  The severance and workforce reduction costs recorded during the three months ended September 23, 2012 included $2.1 million related to other manufacturing facilities in Mexico, California, and Arizona, and $1.2 million for administrative and research and development functions around the world.

The Company continues to review its manufacturing footprint and identify additional cost reduction opportunities, and the nature, timing and extent of the Company's restructuring activities are not yet complete.  Accordingly, and as part of those ongoing efforts, the Company may also incur asset write-downs related to the ultimate disposition of certain manufacturing equipment; any such potential future asset write-downs do not meet the criteria under GAAP to be accrued at this time.

During the first quarter of fiscal year 2013, cash payments for this initiative were $1.9 million and are estimated to be approximately $2.3 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 months ended September 23, 2012 and September 25, 2011, 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 September 23, 2012 and June 24, 2012 was as follows (in thousands):

Income Taxes

13. Income Taxes

The Company's effective tax rate was a tax expense of 31.8 percent against a loss of $21.8 million and a tax expense of 22.2 percent against a profit of $28.2 million for the three months ended September 23, 2012 and September 25, 2011 respectively.  For the three months ended September 23, 2012, the Company's provision for taxes was not comparable to the United States ("U.S.") federal statutory rate of 35 percent.  The main components of the tax provision were a reduction in the U.K. statutory tax rates, reducing the value of the Company's net deferred tax assets in the U.K. by $3.2 million, a $2.2 million expense related to foreign income taxes, foreign withholding taxes, and no tax benefit from the ordinary loss in the U.S. due to the Company's valuation allowance position which were partially offset by benefitting a loss in a foreign jurisdiction.

During the three months ended September 23, 2012, the statutory tax rate in the U.K. was reduced from 25 percent to 24 percent, effective April 1, 2012, and further reduced to 23 percent effective April 1, 2013.  The Company reported a $3.2 million one-time expense due to the rate reduction on the deferred tax assets in the U.K. as a discrete item in the provision for income taxes.

For the three months ended September 25, 2011, the effective rate was lower than the U.S. federal statutory rate of 35 percent primarily due to the utilization of our deferred tax assets through a reduction of the beginning-of-the-year valuation allowance recorded in the U.K. and lower tax rates in certain foreign jurisdictions, and the impact on the tax provision due to the reduction of the U.K. statutory rate.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

13. Income Taxes (Continued)

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 the year balances of reserves that were established during fiscal year 2009.  During fiscal year 2012, the Company had released a remaining $28.6 million valuation allowance established against its deferred tax assets in the United Kingdom ("U.K.") as a result of cumulative pretax income generated by our U.K. subsidiary.

During fiscal years 2011 and 2012, the Company recorded deferred charges and valuation allowances related to certain intercompany transactions which reduced the respective deferred tax assets and associated valuation allowances in the U.K. and U.S.   Due to quarterly amortization of the deferred charge and valuation allowance for the three months ended September 23, 2012, these U.K. items were reduced by $0.7 million and $0.3 million, respectively, with the rest of them being an expense within the tax provision.  As a result of quarterly amortization of the deferred charge and valuation allowance for the three months ended September 23, 2012, these U.S. items were reduced by $0.5 million and $0.4 million, respectively, with the rest of them being an expense within the tax provision.

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.

During the three months ended September 23, 2012, the reserve for uncertain tax positions increased by $0.8 million to $49.7 million.  This increase resulted primarily from changes in currency exchange rates related to prior year uncertain tax positions in certain foreign jurisdictions and additional reserves for state credits accrued during the three months ended September 23, 2012.  For fiscal year 2013, $0.1 million of increases to uncertain tax positions, if recognized, would affect the effective tax rate. The reserve is expected to decrease by $4.4 million during the next 12 months.

As of September 23, 2012, the Company had accrued $3.2 million of interest and penalties related to uncertain tax positions.  For the three months ended September 23, 2012, penalties and interest included in the reserves increased by $0.1 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.  The Company has not recorded a deferred tax liability on any potential gain as the earnings and profits of the subsidiary had been recognized as U.S. income in previous periods.

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 total unrecognized compensation expense for outstanding stock options and RSUs was $38.4 million as of September 23, 2012.  The unrecognized compensation expense for the outstanding stock options and RSUs will generally be recognized over three years, except for one stock option award and one RSU award made to the Chief Executive Officer (the "CEO") during fiscal year 2008.  The compensation expense for the CEO's awards made during fiscal year 2008 is being recognized over 5 years.  The weighted average number of years to recognize the total compensation expense (including that of the CEO) for stock options and RSUs are 0.9 years and 2.2 years, respectively.  As of September 23, 2012, the Company had no RSUs with performance (non-market) based vesting conditions outstanding.

The fair value of the Company stock options issued during the three months ended September 23, 2012 and September 25, 2011, 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 a plan of groundwater monitoring should be undertaken.  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.

INTERNATIONAL RECTIFIER CORPORATION AND SUBSIDIARIES

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.

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 September 2012 and 2011 consisted of 13 weeks ending on September 23, 2012 and September 25, 2011, respectively.

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 or not the inputs are observable in the market and the degree that 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 are also used to value investment securities that included certain asset-backed securities 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 well as consideration of the volatilities of public companies deemed comparable.  As of September 23, 2012, 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.

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.
