NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1)	Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of Microchip Technology Incorporated and its wholly-owned subsidiaries (the Company). All intercompany balances and transactions have been eliminated in consolidation. The Company owns 100% of the outstanding stock in all of its subsidiaries.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). In the opinion of management, all adjustments of a normal recurring nature which are necessary for a fair presentation have been included. Certain information and footnote disclosures normally included in audited consolidated financial statements have been condensed or omitted pursuant to such SEC rules and regulations. It is suggested that these condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2009. The results of operations for the three and six months ended September 30, 2009 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2010 or for any other period.

Subsequent events have been evaluated through November 6, 2009, which is the date the financial statements were issued.

(2)	Adopted and Recently Issued Accounting Pronouncements

Accounting Standards Codification. Effective July 1, 2009, the Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) became the single official source of authoritative, nongovernmental generally accepted accounting principles (GAAP) in the United States. The historical GAAP hierarchy was eliminated and the ASC became the only level of authoritative GAAP, other than guidance issued by the Securities and Exchange Commission. The codification was effective for interim and annual reporting periods ending after September 15, 2009, except for certain nonpublic nongovernmental entities. The Company's accounting policies were not affected by the conversion to ASC. However, references to specific accounting standards in the footnotes to the Company's consolidated financial statements have been changed to refer to the appropriate section of ASC.

Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion. On April 1, 2009, the Company adopted the Cash Conversion Subsections of ASC Subtopic 470-20, Debt with Conversion and Other Options – Cash Conversion (the Cash Conversion Subsections), which clarify the accounting for convertible debt instruments that may be settled in cash (including partial cash settlement) upon conversion. The Cash Conversion Subsections require issuers to account separately for the liability and equity components of certain convertible debt instruments in a manner that reflects the issuer's nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized. The Cash Conversion Subsections require bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest expense in the Company's consolidated statements of operations.

The Cash Conversion Subsections require retrospective application to the terms of instruments as they existed for all periods presented. The adoption of the Cash Conversion Subsections affects the accounting for the Company's 2.125% junior subordinated convertible debentures issued in December 2007 and due in December 2037. The retrospective application of this guidance affects the Company's fiscal years 2008 and 2009.

The following table sets forth the effect of the retrospective application of the Cash Conversion Subsections on certain previously reported line items (in thousands, except per share data):

Fair Value Measurements. In September 2006, the FASB issued guidance which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. In February 2008, the FASB issued additional guidance which deferred the effective date for the Company to April 1, 2009 for all nonfinancial assets and liabilities, except for those that are recognized or disclosed at fair value on a recurring basis (that is, at least annually). The Company adopted the deferred provisions of this guidance on April 1, 2009. The adoption of these provisions did not have a material effect on the Company's consolidated financial statements.

In April 2009, the FASB provided additional guidance on estimating fair value when the volume and level of activity for an asset or liability have significantly decreased in relation to normal market activity for the asset or liability. This guidance also addressed circumstances that may indicate that a transaction is not orderly. The Company adopted this guidance on April 1, 2009 and the adoption had no impact upon the Company's consolidated financial statements.

Interim Disclosures about Fair Value. In April 2009, the FASB issued accounting guidance that requires disclosures by publicly traded companies about the fair value of financial instruments for interim periods as well as in annual financial statements. This guidance is effective for interim reporting periods ending after June 15, 2009, was adopted by the Company on April 1, 2009 and had no impact on the Company's consolidated balance sheets or statements of income or cash flows.

Other-Than-Temporary Impairments. In April 2009, the FASB issued guidance changing existing guidance for determining whether an impairment of debt securities is other than temporary. This guidance requires other than temporary impairments to be separated into the amount representing the decrease in cash flows expected to be collected from a security (referred to as credit losses) which is recognized in earnings and the amount related to other factors which is recognized in other comprehensive income. This noncredit loss

component of the impairment may only be classified in other comprehensive income if the holder of the security concludes that it does not intend to sell and it will not more likely than not be required to sell the security before it recovers its value. If these conditions are not met, the noncredit loss must also be recognized in earnings. When adopting this guidance, an entity is required to record a cumulative effect adjustment as of the beginning of the period of adoption to reclassify the noncredit component of a previously recognized other than temporary impairment from retained earnings to accumulated other comprehensive income. The Company adopted this guidance on April 1, 2009. The Company does not meet the conditions necessary to recognize the noncredit loss component of its auction rate securities in other comprehensive income. Accordingly, the Company did not reclassify any previously recognized other-than-temporary impairment losses from retained earnings to accumulated other comprehensive income and the adoption of this guidance had no impact on the Company's consolidated financial statements. Refer to Note 4 for further discussion of the Company's investments in marketable securities.

Business Combinations. On April 1, 2009, the Company adopted new accounting guidance for business combinations as issued by the FASB. The new accounting guidance establishes principles and requirements for how an acquirer in a business combination recognizes and measures in its financial statements the identifiable assets acquired, liabilities assumed, and any noncontrolling interests in the acquiree, as well as the goodwill acquired. Significant changes from previous guidance resulting from this new guidance include the expansion of the definitions of a "business" and a "business combination." For all business combinations (whether partial, full or step acquisitions), the acquirer will record 100% of all assets and liabilities of the acquired business, including goodwill, generally at their fair values; contingent consideration will be recognized at its fair value on the acquisition date and; for certain arrangements, changes in fair value will be recognized in earnings until settlement; and acquisition-related transaction and restructuring costs will be expensed rather than treated as part of the cost of the acquisition. The new accounting guidance also establishes disclosure requirements to enable users to evaluate the nature and financial effects of the business combination. Because the majority of the provisions of the new accounting guidance are applicable to future transactions, the adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

On April 1, 2009, the Company adopted new accounting guidance for assets acquired and liabilities assumed in a business combination as issued by the FASB. The new guidance amends the provisions previously issued by the FASB related to the initial recognition and measurement, subsequent measurement and accounting and disclosures for assets and liabilities arising from contingencies in business combinations. The new guidance eliminates the distinction between contractual and non-contractual contingencies, including the initial recognition and measurement. The adoption of this accounting guidance did not have a material impact on the Company's consolidated financial statements.

Noncontrolling interests. On April 1, 2009, the Company adopted new accounting guidance for noncontrolling interests in subsidiaries as issued by the FASB. The new accounting guidance establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a noncontrolling interest in a subsidiary, which is sometimes referred to as a minority interest, is a third-party ownership interest in the consolidated entity that should be reported as a component of equity in the consolidated financial statements. Among other requirements, the new guidance requires the consolidated statement of income to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest. The new guidance also requires disclosure on the face of the consolidated statement of income of the amounts of consolidated net income attributable to the parent and to the noncontrolling interest. The adoption of this accounting guidance did not have an impact on the Company's consolidated financial statements.

Determining the Useful Life of Intangible Assets. During the first quarter of fiscal 2010, the Company adopted new accounting guidance for the determination of the useful life of intangible assets as issued by the FASB. The new guidance amends the factors that should be considered in developing the renewal or extension assumptions used to determine the useful life of a recognized intangible asset. The new guidance also requires expanded disclosure regarding the determination of intangible asset useful lives. Because this accounting guidance is applicable to future transactions, the adoption of this accounting guidance did not have an impact on the Company's consolidated financial statements.

Subsequent Events. During the first quarter of fiscal 2010, the Company adopted new accounting guidance related to subsequent events as issued by the FASB. The new requirement establishes the accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. It requires the disclosure of the date through which an entity has evaluated subsequent events and the basis for that date, that is, whether that date represents the date the financial statements were or were available to be issued. The adoption of these provisions did not have a material effect on the Company's consolidated financial statements. See Note 1 for additional discussion of the Company's evaluation of subsequent events.

Transfers of Financial Assets. In June 2009, the FASB issued guidance that changes the information a reporting entity provides in its financial statements about the transfer of financial assets and continuing interests held in transferred financial assets. The standard amends previous accounting guidance by removing the concept of qualified special purpose entities. This accounting standard is effective for the Company for transfers occurring on or after April 1, 2010. The Company does not expect the adoption of this accounting standard to have a material effect on its consolidated financial statements and related disclosures.

Variable Interest Entities. In June 2009, the FASB issued guidance to change financial reporting by enterprises involved with variable interest entities (VIEs). The standard replaces the quantitative-based risks and rewards calculation for determining which enterprise has a controlling financial interest in a VIE with an approach focused on identifying which enterprise has the power to direct the activities of a VIE and the obligation to absorb losses of the entity or the right to receive the entity's residual returns. This accounting standard is effective for the Company on April 1, 2010. The Company does not expect the adoption of this accounting standard to have a material effect on its consolidated financial statements and related disclosures.

Fair Value Measurement of Liabilities. In August 2009, FASB issued guidance providing clarification that in circumstances in which a quoted price in an active market for the identical liability is not available, a reporting entity is required to measure fair value using one or more of the following techniques:

1. A valuation technique that uses:

a. The quoted price of the identical liability when traded as an asset.

b. Quoted prices for similar liabilities or similar liabilities when traded as assets.

2. Another valuation technique that is consistent with the principles in the FASB's guidance (two examples would be an income approach or a market approach).

This guidance also clarifies that (i) when estimating the fair value of a liability, a reporting entity is not required to include a separate input or adjustment to other inputs relating to the existence of a restriction that prevents the transfer of the liability and (ii) both a quoted price in an active market for the identical liability at the measurement date and the quoted price for the identical liability when traded as an asset in an active market when no adjustments to the quoted price of the asset are required are Level 1 fair value measurements. This guidance is effective for the first reporting period (including interim periods) beginning after issuance. The Company does not expect this guidance to have a material impact on its consolidated financial statements and disclosures.

Multiple Element Arrangements. In September 2009, the FASB issued new accounting guidance related to the revenue recognition of multiple element arrangements. The new guidance states that if vendor specific objective evidence or third party evidence for deliverables in an arrangement cannot be determined, companies will be required to develop a best estimate of the selling price to separate deliverables and allocate arrangement consideration using the relative selling price method. The Company is currently evaluating the impact of this accounting guidance on its consolidated financial statements.

Certain Revenue Arrangements that include Software Elements. In September 2009, the FASB issued new accounting guidance related to certain revenue arrangements that include software elements. Previously, companies that sold tangible products with "more than incidental" software were required to apply software revenue recognition guidance. This guidance often delayed revenue recognition for the delivery of the tangible product. Under the new guidance, tangible products that have software components that are "essential to the functionality" of the tangible product will be excluded from the software revenue recognition guidance. The new guidance will include factors to help companies determine what is "essential to the functionality." Software-enabled products will now be subject to other revenue guidance including that for multiple deliverable arrangements issued by the FASB in September 2009. The Company is currently evaluating the impact of this accounting guidance on its consolidated financial statements.

(3) Special Charge

During the three months ended June 30, 2009, the Company agreed to the terms of a patent license with an unrelated third-party and signed an agreement on July 9, 2009. The patent license settled alleged infringement claims. The total payment made to the third-party in July 2009 was $1.4 million, $1.2 million of which was expensed in the first quarter of fiscal 2010 and the remaining $0.2 million was recorded as a prepaid royalty that will be amortized over the remaining life of the patent, which expires in June 2010.

(4) Investments

The Company's investments are intended to establish a high-quality portfolio that preserves principal, meets liquidity needs, and delivers an appropriate yield in relationship to the Company's investment guidelines and market conditions.

At September 30, 2009, the Company's available-for-sale and trading securities are presented on the condensed consolidated balance sheets as short-term investments of $822.9 million and long-term investments of $108.7 million.

The Company has classified its strategic investments in publicly traded companies as trading securities. During the three months ended September 30, 2009, the Company sold all but $4,000 of the $29.8 million of trading securities that it owned at June 30, 2009. During the three and six months ended September 30, 2009, the Company recognized a gain in earnings of $1.9 million and $6.6 million, respectively, on these trading securities. The Company had a net realized gain of $4.9 million and $1.0 million, respectively, on trading securities that it sold during the three and six months ended September 30, 2009.

At September 30, 2009, $45.3 million of the fair value of the Company's investment portfolio was invested in auction rate securities (ARS). With the continuing liquidity issues in the global credit markets, the Company's ARS have experienced multiple failed auctions. In September 2007 and February 2008, auctions for $24.9 million and $34.8 million, respectively, of the original purchase value of the Company's investments in ARS first failed. While the Company continues to earn interest on these investments based on a pre-determined formula with spreads tied to particular interest rate indices, the estimated market value for these ARS no longer approximates the original purchase value.

The $24.9 million in failed auctions have continued to fail through the filing date of this Quarterly Report on Form 10-Q. The fair value of the failed ARS of $17.3 million has been estimated based on market information and estimates determined by management and could change significantly based on market conditions. The Company evaluated the impairments in the value of these ARS, determining its intent to sell these securities prior to the recovery of its amortized cost basis resulted in the securities being other-than-temporarily impaired and has recognized an impairment charge on these investments of $0.4 million in the quarter ended September 30, 2009. The Company intends to sell the $24.9 million of ARS.

The $34.8 million of ARS that failed during February 2008 are investments in student loan-backed ARS. Approximately $1.4 million and $2.9 million of these ARS were redeemed at par by the issuers in the six months ended September 30, 2009 and fiscal 2009, respectively, reducing the Company's overall position to $30.5 million. Based upon the Company's evaluation of available information, it believes these investments are of high credit quality, as all of the investments carry AAA credit ratings by one or more of the major credit rating agencies and are largely backed by the federal government (Federal Family Education Loan Program). The fair value of the failed ARS has been estimated based on market information and estimates determined by management and could change significantly based on market conditions. In November 2008, the Company executed an ARS rights agreement (the Rights) with the broker through which the Company purchased the $30.5 million in ARS that provides (1) the Company with the right to put these ARS back to the broker at par anytime during the period from June 30, 2010 through July 2, 2012, and (2) the broker with the right to purchase or sell the ARS at par on the Company's behalf anytime through July 2, 2012. The Company accounted for the acceptance of the Rights as the receipt of a put option for no consideration and recognized a gain with a corresponding recognition as a long-term investment. The Company expects any future changes in the fair value of the ARS to be largely offset by changes in the fair value of the related Rights without any significant net impact to the Company's income statement. The Company will continue to measure the ARS and the Rights at fair value (utilizing Level 3 inputs) until the earlier of maturity or exercise. The Company intends and has the ability to hold the $30.5 million of ARS until the market recovers or until June 30, 2010 when it has the right to sell the ARS at par to the broker as it does not anticipate having to sell these securities to fund the operations of its business.

The Company believes that, based on its current unrestricted cash, cash equivalents and short-term investment balances, the current lack of liquidity in the credit markets will not have a material impact on its liquidity, cash flow or ability to fund its operations.

At September 30, 2009, the Company evaluated its investment portfolio and noted unrealized losses of $0.3 million which were due to fluctuations in interest rates and credit market conditions. Management does not believe any of the unrealized losses represent other-than-temporary impairment based on its evaluation of available evidence as of September 30, 2009. The Company's intent is to hold these investments until these assets are no longer impaired. For those investments not scheduled to mature until after June 30, 2010, such recovery is not anticipated to occur in the next year and these investments have been classified as long-term investments.

The amortized cost and estimated fair value of the available-for-sale securities at September 30, 2009, by maturity, are shown below (amounts in thousands). Expected maturities can differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties, and the Company views its available-for-sale securities as available for current operations.

	Adjusted Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value
Available-for-sale
Due in one year or less	$	461,993	$	3,003	$	---	$	464,996
Due after one year and through five years		416,144		3,078		328		418,894
Due after five years and through ten years		---		---		---		---
Due after ten years		17,259		---		---		17,259
	$	895,396	$	6,081	$	328	$	901,149

During the quarter ended September 30, 2009, the Company had a realized gain of $7,000 from sales of available-for-sale securities compared to no realized gains or losses in the quarter ended June 30, 2009.

(5) Fair Value Measurements

Accounting rules for fair value clarify that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 – Observable inputs such as quoted prices in active markets;

Level 2 – Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Assets and liabilities measured at fair value on a recurring basis at September 30, 2009 are as follows (amounts in thousands):

	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Balance
Assets

Total assets measured at fair value	$	329,343	$	1,095,596	$	47,784	$	1,472,723

For Level 3 valuations, the Company estimated the fair value of its ARS based on the following: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; (iii) consideration of the probabilities of default, auction failure, or repurchase at par for each period; and (iv) estimates of the recovery rates in the event of default for each security. The Company estimated the value of the put option on the ARS by evaluating the estimated cash flows before and after the receipt of the put option, discounted at rates reflecting the likelihood of default and lack of liquidity, or in the case of the payment of the par value to be paid by the broker at exercise of the put option, the counterparty credit risk. The estimated fair values that are categorized as Level 3 as well as the marketable securities and put options on publicly traded stock could change significantly based on future market conditions. Refer to Note 4 for further discussion of the Company's investments in ARS.

The following table presents a reconciliation for all assets and liabilities measured at fair value on a recurring basis, excluding accrued interest components, using significant unobservable inputs (Level 3) for the three months ended September 30, 2009 (amounts in thousands):

	Three Months Ended September 30, 2009			Six Months Ended September 30, 2009

Total assets measured at fair value	$	329,343	$	1,095,596	$	47,784	$	1,472,723

(6)	Fair Value of Financial Instruments

The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. The carrying amount of short-term and long-term investments approximates fair value as the securities are marked to market as of each balance sheet date with any unrealized gains and losses reported in stockholders' equity. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts. The fair value of the Company's junior subordinated convertible debentures was $1,055.2 million at September 30, 2009, based on the trading price of the bonds, compared to the carrying value of $337.4 million. See Note 11 for additional information regarding the carrying value of the Company's junior subordinated convertible debentures.

(7)	Accounts Receivable

Accounts receivable consists of the following (amounts in thousands):

	September 30, 2009		March 31, 2009
Trade accounts receivable	$	109,315	$	91,325
Other		556		376
		109,871		91,701
Less allowance for doubtful accounts		3,220		3,176
	$	106,651	$	88,525

(8)	Inventories

	September 30, 2009		March 31, 2009
Raw materials	$	3,886	$	3,693
Work in process		91,770		114,676
Finished goods		12,795		13,141
	$	108,451	$	131,510

Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable.

(9)	Property, Plant and Equipment

Property, plant and equipment consists of the following (amounts in thousands):

	September 30, 2009		March 31, 2009
Land	$	39,671	$	39,671
Building and building improvements		335,578		334,717
Machinery and equipment		1,162,588		1,148,588
Projects in process		104,341		114,478

Less accumulated depreciation and amortization		1,144,220		1,105,767
	$	497,958	$	531,687

Depreciation expense attributed to property, plant and equipment was $43.5 million in the six months ended September 30, 2009 and $47.2 million in the six months ended September 30, 2008.

(10) Income Taxes

The provision for income taxes reflects tax on foreign earnings and federal and state tax on U.S. earnings. The Company had an effective tax rate of 14.4% for the six-month period ended September 30, 2009 and 17.8% for the six-month period ended September 30, 2008. The Company's effective tax rate is lower than statutory rates in the U.S. due primarily to its mix of earnings in foreign jurisdictions with lower tax rates.

At March 31, 2009, the Company had $70.1 million of unrecognized tax benefits. Unrecognized tax benefits increased by $5.5 million in the six months ended September 30, 2009 compared to the March 31, 2009 balances as a result of the accrual for uncertain tax positions and the accrual of deficiency interest on these positions.

The Company files U.S. federal, U.S. state, and foreign income tax returns. For U.S. federal, and in general for U.S. state tax returns, the fiscal 2002 through fiscal 2004 and fiscal 2006 through fiscal 2009 tax years remain open for examination by tax authorities. For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2002.

The Company recognizes liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on its estimate of whether, and the extent to which, additional tax payments are more likely than not. The Company believes that it maintains adequate reserves to offset any potential income tax liabilities that may arise upon final resolution of matters for open tax years. The U.S. IRS is currently auditing the Company's fiscal years ended March 31, 2002, 2003, 2004, 2006, 2007 and 2008. The Company believes that it has appropriate support for the income tax positions taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter.

If such amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary. If such amounts prove to be less than an ultimate assessment, a future charge to expense would be recorded in the period in which the assessment is determined. Although the timing of the resolution and/or closure on audits is highly uncertain, the Company does not believe it is reasonably possible that its unrecognized tax benefits would materially change in the next 12 months.

(11) 2.125% Junior Subordinated Convertible Debentures

The Company's $1.15 billion principal amount of 2.125% junior subordinated convertible debentures due December 15, 2037, are subordinated in right of payment to any future senior debt of the Company and are effectively subordinated in right of payment to the liabilities of the Company's subsidiaries. The debentures are convertible, subject to certain conditions, into shares of the Company's common stock at an initial conversion rate of 29.2783 shares of common stock per $1,000 principal amount of debentures, representing an initial conversion price of approximately $34.16 per share of common stock. As of September 30, 2009, none of the conditions allowing holders of the debentures to convert had been met. As a result of a cash dividend of $0.339 per share paid in September 2009, the conversion rate was adjusted to 32.1283 shares of common stock per $1,000 of principal amount of debentures, representing a conversion price of approximately $31.13 per share of common stock.

As the debentures can be settled in cash upon conversion, for accounting purposes, the debentures were bifurcated into a liability component and an equity component, which are initially recorded at fair value. The carrying value of the equity component at September 30, 2009 and at March 31, 2009 was $822.4 million. The estimated fair value of the liability component of the debentures at the issuance date was $327.6 million, resulting in a debt discount of $822.4 million. The unamortized debt discount was $811.9 million at September 30, 2009 and $815.0 million at March 31, 2009. The carrying value of the debentures was $337.4 million at September 30, 2009 and $334.2 million at March 31, 2009. The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is 28.25 years. In the three and six months ended September 30, 2009, the Company recognized $1.6 million and $3.1 million, respectively, in non-cash interest expense related to the amortization of the debt discount. In the three and six months ended September 30, 2008, the Company recognized $1.4 million and $2.8 million, respectively, in non-cash interest expense related to the amortization of the debt discount. The Company recognized $6.1 million and $12.2 million of interest expense related to the 2.125% coupon on the debentures in the three and six months ended September 30, 2009 and 2008, respectively.

The debentures also include certain embedded features related to the contingent interest payments, the Company making specific types of distributions (e.g., extraordinary dividends), the redemption feature in the event of changes in tax law, and penalty interest in the event of a failure to maintain an effective registration. These features qualify as derivatives and are bundled as a compound embedded derivative that is measured at fair value. The fair value of the derivative as of September 30, 2009 was $0.6 million, compared to the value at March 31, 2009 of $0.5 million, resulting in an increase of interest expense in the first six months of fiscal 2010 of $0.1 million. The balance of the debentures on the Company's condensed consolidated balance sheet at September 30, 2009 of $337.4 million includes the fair value of the embedded derivative.

(12) Derivative Instruments

The Company has international operations and is thus subject to foreign currency rate fluctuations. To manage the risk of changes in foreign currency rates, the Company periodically enters into derivative contracts comprised of foreign currency forward contracts to hedge its asset and liability foreign currency exposure and a portion of its foreign currency operating expenses. Approximately 99% of the Company's sales are U.S. Dollar denominated. To date, the exposure related to foreign exchange rate volatility has not been material to the Company's operating results. As of September 30, 2009 and March 31, 2009, the Company had no foreign currency derivatives outstanding. The Company recognized an immaterial amount of net realized gains on foreign currency derivatives in the six months ended September 30, 2009.

(13)	Comprehensive Income

Comprehensive income consists of net income offset by net unrealized gains and losses on available-for-sale investments. The components of other comprehensive income and related tax effects were as follows (amounts in thousands):

	Three Months Ended September 30,						Six Months Ended September 30,
	2009			2008			2009			2008
Change in unrealized gains and losses on investments, net of tax effect of $432, $67, $975 and $942, respectively	$	(68	)	$	(18	)	$	(37	)	$	3,201

Comprehensive income was $44.6 million and $71.9 million for the three and six months ended September 30, 2009 and $75.7 million and $148.1 million for the three and six months ended September 30, 2008, respectively.

(1) During the three and six months ended September 30, 2009, $1.8 million and $3.6 million, respectively, was capitalized to inventory and $1.9 million and $3.6 million, respectively, of previously capitalized inventory was sold. During the three and six months ended September 30, 2008, $1.7 million and $3.1 million, respectively, was capitalized to inventory and $2.1 million and $3.7 million, respectively, of previously capitalized inventory was sold.

The amount of unearned share-based compensation currently estimated to be expensed in the remainder of fiscal 2010 through fiscal 2014 related to unvested share-based payment awards at September 30, 2009 is $54.1 million. The weighted average period over which the unearned share-based compensation is expected to be recognized is approximately 2.27 years.

Combined Incentive Plan Information

The total intrinsic value of restricted stock units (RSUs) which vested during the three and six months ended September 30, 2009 was $4.2 million and $6.7 million, respectively. The aggregate intrinsic value of RSUs outstanding at September 30, 2009 was $109.5 million, calculated based on the closing price of the Company's common stock of $26.50 per share on September 30, 2009. At September 30, 2009, the weighted average remaining expense recognition period was 2.37 years.

The weighted average fair value per share of the RSUs awarded is calculated based on the fair market value of the Company's common stock on the respective grant dates discounted for the Company's expected dividend yield. The weighted average fair value per share of RSUs awarded in the three and six months ended September 30, 2009 was $19.10 and $18.08, respectively. The weighted average fair value per share of RSUs awarded in the three and six months ended September 30, 2008 was $26.74 and $27.36, respectively.

The total intrinsic value of options exercised during the three and six months ended September 30, 2009 was $2.0 million and $2.3 million, respectively. This intrinsic value represents the difference between the fair market value of the Company's common stock on the date of exercise and the exercise price of each equity award.

The aggregate intrinsic value of options outstanding and options exercisable at September 30, 2009 was $25.8 million and $25.0 million, respectively. The aggregate intrinsic values were calculated based on the closing price of the Company's common stock of $26.50 per share on September 30, 2009.

For the three months ended September 30, 2009 and 2008, the number of option shares exercisable was 8,930,713 and 8,310,342, respectively, and the weighted average exercise price per share was $24.24 and $23.02, respectively.

The weighted average fair value per share of stock options granted in the three months ended September 30, 2009 was $5.90. The weighted average fair value per share of stock options granted in the three months ended September 30, 2008 was $10.39. There were no stock options granted in the three-month periods ended June 30, 2009 and 2008.

(15)	Net Income Per Common Share

The following table sets forth the computation of basic and diluted net income per common share (in thousands, except per share amounts):

	Three Months Ended September 30,				Six Months Ended September 30,
	2009		2008		2009		2008
Net income	$	44,485	$	75,720	$	71,853	$	151,267
Weighted average common shares outstanding		183,190		183,615		183,023		184,139
Dilutive effect of stock options and RSUs		3,732		4,321		3,201		4,765
Dilutive effect of convertible debt		---		---		---		589
Weighted average common and potential common shares outstanding		186,922		187,936		186,224		189,493
Basic net income per common share	$	0.24	$	0.41	$	0.39	$	0.82
Diluted net income per common share	$	0.24	$	0.40	$	0.39	$	0.80

Diluted net income per common share for the three and six months ended September 30, 2009 does not include any incremental shares issuable upon the exchange of the debentures (see Note 11). The three-month period ended September 30, 2008 does not include any incremental shares issuable upon the exchange of the debentures. The six-month period ended September 30, 2008 includes 588,892 incremental shares issuable upon the exchange of the debentures. The debentures have no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion. Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method. The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for the three and six months ended September 30, 2009 was $31.35 and $31.59, respectively.

Weighted average common shares exclude the effect of anti-dilution option shares. As of the three and six-month periods ended September 30, 2009, the number of option shares that were antidilutive was 4,250,079 and 6,033,106, respectively. As of the three and six-month periods ended September 30, 2008, the number of option shares that were antidilutive was 275,102 and 149,529, respectively.

(16)	Stock Repurchase

During the three and six months ended September 30, 2009, the Company did not repurchase any of its shares of common stock. During the three and six months ended September 30, 2008, the Company purchased 3.3 million and 4.0 million shares of its common stock for a total of $100.3 million and $123.9 million, respectively. The timing and amount of future repurchases will depend upon market conditions, interest rates, and corporate considerations.

As of September 30, 2009, the Company held approximately 35.2 million shares as treasury shares.

(17)

Dividends

A quarterly cash dividend of $0.339 per share was paid on September 3, 2009 in the aggregate amount of $62.1 million. A quarterly cash dividend of $0.34 per share was declared on November 4, 2009 and will be paid on December 2, 2009 to shareholders of record as of November 18, 2009. The Company expects the December 2009 payment of its quarterly cash dividend to be approximately $62.3 million.

We begin our Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) with a summary of Microchip's overall business strategy to give the reader an overview of the goals of our business and the overall direction of our business and products. This is followed by a discussion of the Critical Accounting Policies and Estimates that we believe are important to understanding the assumptions and judgments incorporated in our reported financial results. We then discuss our Results of Operations for the three and six months ended September 30, 2009 compared to the three and six months ended September 30, 2008. We then provide an analysis of changes in our balance sheet and cash flows, and discuss our financial commitments in sections titled "Liquidity and Capital Resources," "Contractual Obligations" and "Off-Balance Sheet Arrangements."

Strategy

Our goal is to be a worldwide leader in providing specialized semiconductor products for a wide variety of embedded control applications. Our strategic focus is on embedded control products, which include microcontrollers, high-performance linear and mixed signal devices, power management and thermal management devices, interface devices, Serial EEPROMs, and our patented KeeLoq® security devices. We provide highly cost-effective embedded control products that also offer the advantages of small size, high performance, low voltage/power operation and ease of development, enabling timely and cost-effective embedded control product integration by our customers.

We sell our products to a broad base of domestic and international customers across a variety of industries. The principal markets that we serve include consumer, automotive, industrial, office automation and telecommunications. Our business is subject to fluctuations based on economic conditions within these markets. Beginning with the third quarter of fiscal 2009, the downturn in the U.S. and global economies has adversely impacted our key markets resulting in adverse fluctuations in our business; however, in the first two quarters of fiscal 2010 we saw an upturn in our key markets, resulting in improvements to our business, though not the levels of revenue and profitability that we realized in the same periods in fiscal 2009.

Our manufacturing operations include wafer fabrication and assembly and test. The ownership of our manufacturing resources is an important component of our business strategy, enabling us to maintain a high level of manufacturing control resulting in us being one of the lowest cost producers in the embedded control industry. By owning our wafer fabrication facilities and our assembly and test operations, and by employing statistical process control techniques, we have been able to achieve and maintain high production yields. Direct control over manufacturing resources allows us to shorten our design and production cycles. This control also allows us to capture the wafer manufacturing and a portion of the assembly and test profit margin.

We employ proprietary design and manufacturing processes in developing our embedded control products. We believe our processes afford us both cost-effective designs in existing and derivative products and greater functionality in new product designs. While many of our competitors develop and optimize separate processes for their logic and memory product lines, we use a common process technology for both microcontroller and non-volatile memory products. This allows us to more fully leverage our process research and development costs and to deliver new products to market more rapidly. Our engineers utilize advanced computer-aided design (CAD) tools and software to perform circuit design, simulation and layout, and our in-house photomask and wafer fabrication facilities enable us to rapidly verify design techniques by processing test wafers quickly and efficiently.

We are committed to continuing our investment in new and enhanced products, including development systems, and in our design and manufacturing process technologies. We believe these investments are significant factors in maintaining our competitive position. Our current research and development activities focus on the design of new microcontrollers, digital signal controllers, memory and mixed-signal products, new development systems, software and application-specific software libraries. We are also developing new design and process technologies to achieve further cost reductions and performance improvements in our products.

We market our products worldwide primarily through a network of direct sales personnel and distributors. Our distributors focus primarily on servicing the product and technical support requirements of a broad base of diverse customers. We believe that our direct sales personnel combined with our distributors provide an effective means of reaching this broad and diverse customer base. Our direct sales force focuses primarily on major strategic accounts in three geographical markets: the Americas, Europe and Asia. We currently maintain sales and support centers in major metropolitan areas in North America, Europe and Asia. We believe that a strong technical service presence is essential to the continued development of the embedded control market. Many of our field sales engineers (FSEs), field application engineers (FAEs), and sales management have technical degrees and have been previously employed in an engineering environment. We believe that the technical knowledge of our sales force is a key competitive advantage in the sale of our products. The primary mission of our FAE team is to provide technical assistance to strategic accounts and to conduct periodic training sessions for FSEs and distributor sales teams. FAEs also frequently conduct technical seminars for our customers in major cities around the world, and work closely with our distributors to provide technical assistance and end-user support.

Critical Accounting Policies and Estimates

General

Our discussion and analysis of Microchip's financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. We review the accounting policies we use in reporting our financial results on a regular basis. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, share-based compensation, inventories, investments, income taxes, property plant and equipment, impairment of property, plant and equipment, junior subordinated convertible debentures and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Our results may differ from these estimates due to actual outcomes being different from those on which we based our assumptions. We review these estimates and judgments on an ongoing basis. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements. We also have other policies that we consider key accounting policies, such as our policy regarding revenue recognition to OEMs; however, we do not believe these policies require us to make estimates or judgments that are as difficult or subjective as our policies described below.

Revenue Recognition - Distributors

Our distributors worldwide generally have broad price protection and product return rights, so we defer revenue recognition until the distributor sells the product to their customer. Revenue is recognized when the distributor sells the product to an end-customer, at which time the sales price becomes fixed or determinable. Revenue is not recognized upon shipment to our distributors since, due to discounts from list price as well as price protection rights, the sales price is not substantially fixed or determinable at that time. At the time of shipment to these distributors, we record a trade receivable for the selling price as there is a legally enforceable right to payment, relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor, and record the gross margin in deferred income on shipments to distributors on our condensed consolidated balance sheets.

Deferred income on shipments to distributors effectively represents the gross margin on the sale to the distributor; however, the amount of gross margin that we recognize in future periods could be less than the deferred margin as a result of credits granted to distributors on specifically identified products and customers to allow the distributors to earn a competitive gross margin on the sale of our products to their end customers and price protection concessions related to market pricing conditions.

We sell the majority of the items in our product catalog to our distributors worldwide at a uniform list price. However, distributors resell our products to end customers at a very broad range of individually negotiated price points. The majority of our distributors' resales require a reduction from the original list price paid. Often, under these circumstances, we remit back to the distributor a portion of their original purchase price after the resale transaction is completed in the form of a credit against the distributors' outstanding accounts receivable balance. The credits are on a per unit basis and are not given to the distributor until they provide information to us regarding the sale to their end customer. The price reductions vary significantly based on the customer, product, quantity ordered, geographic location and other factors and discounts to a price less than our cost have historically been rare. The effect of granting these credits establishes the net selling price to our distributors for the product and results in the net revenue recognized by us when the product is sold by the distributors to their end customers. Thus, a portion of the "deferred income on shipments to distributors" balance represents the amount of distributors' original purchase price that will be credited back to the distributor in the future. The wide range and variability of negotiated price concessions granted to distributors does not allow us to accurately estimate the portion of the balance in the deferred income on shipments to distributors account that will be credited back to the distributors. Therefore, we do not reduce deferred income on shipments to distributors or accounts receivable by anticipated future concessions; rather, price concessions are typically recorded against deferred income on shipments to distributors and accounts receivable when incurred, which is generally at the time the distributor sells the product. At September 30, 2009, we had approximately $125.8 million of deferred revenue and $39.5 million in deferred cost of sales recognized as $86.3 million of deferred income on shipments to distributors. At March 31, 2009, we had approximately $118.2 million of deferred revenue and $34.3 million in deferred cost of sales recognized as $83.9 million of deferred income on shipments to distributors. The deferred income on shipments to distributors that will ultimately be recognized in our income statement will be lower than the amount reflected on the balance sheet due to additional price credits to be granted to the distributors when the product is sold to their customers. These additional price credits historically have resulted in the deferred income approximating the overall gross margins that we recognize in the distribution channel of our business.

Distributor advances, reflected as a reduction of deferred income on shipments to distributors on our condensed consolidated balance sheets, totaled $47.5 million at September 30, 2009 and $37.6 million at March 31, 2009. On sales to distributors, our payment terms generally require the distributor to settle amounts owed to us for an amount in excess of their ultimate cost. The sales price to our distributors may be higher than the amount that the distributors will ultimately owe us because distributors often negotiate price reductions after

purchasing the product from us and such reductions are often significant. It is our practice to apply these negotiated price discounts to future purchases, requiring the distributor to settle receivable balances, on a current basis, generally within 30 days, for amounts originally invoiced. This practice has an adverse impact on the working capital of our distributors. As such, we have entered into agreements with certain distributors whereby we advance cash to the distributors to reduce the distributor's working capital requirements. These advances are reconciled at least on a quarterly basis and are estimated based on the amount of ending inventory as reported by the distributor multiplied by a negotiated percentage. Such advances have no impact on our revenue recognition or our condensed consolidated statements of income. We process discounts taken by distributors against our deferred income on shipments to distributors' balance and true-up the advanced amounts generally after the end of each completed fiscal quarter. The terms of these advances are set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and are due upon demand. The agreements governing these advances can be cancelled by us at any time.

We reduce product pricing through price protection based on market conditions, competitive considerations and other factors. Price protection is granted to distributors on the inventory they have on hand at the date the price protection is offered. When we reduce the price of our products, it allows the distributor to claim a credit against its outstanding accounts receivable balances based on the new price of the inventory it has on hand as of the date of the price reduction. There is no immediate revenue impact from the price protection, as it is reflected as a reduction of the deferred income on shipments to distributors' balance.

Products returned by distributors and subsequently scrapped have historically been immaterial to our consolidated results of operations. We routinely evaluate the risk of impairment of the deferred cost of sales component of the deferred income on shipments to distributors account. Because of the historically immaterial amounts of inventory that have been scrapped, and historically rare instances where discounts given to a distributor result in a price less than our cost, we believe the deferred costs are recorded at their approximate carrying value.

Share-Based Compensation

We measure at fair value and recognize compensation expense for all share-based payment awards, including grants of employee stock options, RSUs and employee stock purchase rights, to be recognized in our financial statements based on their respective grant date fair values. Total share-based compensation during the six months ended September 30, 2009 was $18.5 million, of which $14.9 million was reflected in operating expenses. Total share-based compensation reflected in cost of sales during the six months ended September 30, 2009 was $3.6 million. Total share-based compensation included in our inventory balance was $3.2 million at September 30, 2009.

Determining the appropriate fair-value model and calculating the fair value of share-based awards at the date of grant requires judgment. The fair value of our RSUs is based on the fair market value of our common stock on the date of grant discounted for expected future dividends. We use the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under stock participation plans. Option pricing models, including the Black-Scholes model, also require the use of input assumptions, including expected volatility, expected life, expected dividend rate, and expected risk-free rate of return. We use a blend of historical and implied volatility based on options freely traded in the open market as we believe this is more reflective of market conditions and a better indicator of expected volatility than using purely historical volatility. The expected life of the awards is based on historical and other economic data trended into the future. The risk-free interest rate assumption is based on observed interest rates appropriate for the terms of our awards. The dividend yield assumption is based on our history and expectation of future dividend payouts. We estimate the number of share-based awards that will be forfeited due to employee turnover. Quarterly changes in the estimated forfeiture rate can have a significant effect on reported share-based compensation, as the effect of adjusting the rate for all expense amortization after April 1, 2006 is recognized in the period the forfeiture estimate is changed. If the actual forfeiture rate is higher or lower than the estimated forfeiture rate, then an adjustment is made to increase or decrease the estimated forfeiture rate, which will result in a decrease or increase to the expense recognized in our financial statements. If forfeiture adjustments are made, they would affect our gross margin, research and development expenses, and selling, general, and administrative expenses. The effect of forfeiture adjustments through the second quarter of fiscal 2010 was immaterial.

We evaluate the assumptions used to value our awards on a quarterly basis. If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, we may be required to accelerate, increase or cancel any remaining unearned share-based compensation expense. Future share-based compensation expense and unearned share-based compensation will increase to the extent that we grant additional equity awards to employees or we assume unvested equity awards in connection with acquisitions.

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out method. We write down our inventory for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those we projected, additional inventory write-downs may be required. Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable. In estimating our inventory obsolescence, we primarily evaluate estimates of demand over a 12-month period and record impairment charges for inventory on hand in excess of the estimated 12-month demand.

In periods where our production levels are substantially below our normal operating capacity, such as in the second half of fiscal 2009 and the first half of fiscal 2010, the reduced production levels of our manufacturing facilities are charged directly to cost of sales.

Investments

We classify our investments as trading securities or available-for-sale securities based upon management's intent with regard to the investments and the nature of the underlying securities.

Our trading securities have consisted of strategic investments in shares of publicly traded common stock and ARS that we intend to dispose of through the exercise of a put option. (See Note 4 to our condensed consolidated financial statements for further discussion of the put option.) Our investments in trading securities are carried at fair value with unrealized gains and losses reported in Other, net, in the consolidated statements of income.

Our available-for-sale investments consist of government agency bonds, municipal bonds, ARS, and corporate bonds. Our investments are carried at fair value with unrealized gains and losses reported in stockholders' equity. Premiums and discounts are amortized or accreted over the life of the related available-for-sale security. Dividend and interest income are recognized when earned. The cost of securities sold is calculated using the specific identification method.

We include within our short-term investments our trading securities, as well as our income yielding available-for-sale securities that can be readily converted to cash and include within long-term investments those income yielding available-for-sale securities with maturities of over one year that have unrealized losses attributable to them or those that cannot be readily liquidated. We have the ability to hold our long-term investments with temporary impairments until such time as these assets are no longer impaired. Such recovery of unrealized losses is not expected to occur within the next year.

Due to the lack of availability of observable market quotes on certain of our investment portfolio of ARS, we utilize valuation models including those that are based on expected cash flow streams and collateral values, including assessments of counterparty credit quality, default risk underlying the security, discount rates and overall capital market liquidity. The valuation of our ARS investment portfolio is subject to uncertainties that are difficult to predict. Factors that may impact our ARS valuation include changes to credit ratings of the securities as well as to the underlying assets supporting those securities, rates of default of the underlying assets, underlying collateral value, discount rates, counterparty risk, the ongoing strength and quality of the credit markets and market liquidity.

The credit markets experienced significant deterioration and uncertainty beginning in the second half of fiscal 2008. If these conditions continue, or we experience any additional ratings downgrades on any investments in our portfolio (including our ARS), we may incur additional impairments to our investment portfolio, which could negatively affect our financial condition, cash flow and reported earnings.

Income Taxes

As part of the process of preparing our condensed consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our condensed consolidated balance sheets. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income within the relevant jurisdiction and to the extent we believe that recovery is not likely, we must establish a valuation allowance. We have not provided for a valuation allowance because we believe that it is more likely than not that our deferred tax assets will be recovered from future taxable income. Should we determine that we would not be able to realize all or part of our net deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was made. At September 30, 2009, our gross deferred tax asset was $78.1 million.

Various taxing authorities in the U. S. and other countries in which we do business scrutinize the tax structures employed by businesses. Companies of our size and complexity are regularly audited by the taxing authorities in the jurisdictions in which they conduct significant operations. We are currently under audit by the United States Internal Revenue Service (IRS) for our fiscal years ended March 31, 2002, 2003, 2004, 2006, 2007 and 2008. We recognize liabilities for anticipated tax audit issues in the U. S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional tax payments are probable. We believe that we maintain adequate tax reserves to offset any potential tax liabilities that may arise upon these and other pending audits in the U. S. and other countries in which we do business. If such amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary. If such amounts ultimately prove to be less than an ultimate assessment, a future charge to expense would be recorded in the period in which the assessment is determined.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Major renewals and improvements are capitalized, while maintenance and repairs are expensed when incurred. At September 30, 2009, the carrying value of our property and equipment totaled $498.0 million, which represented 20.6% of our total assets. This carrying value reflects the application of our property and equipment accounting policies, which incorporate estimates, assumptions and judgments relative to the useful lives of our property and equipment. Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets, which range from 5 to 7 years on manufacturing equipment, from 10 to 15 years on leasehold improvements and approximately 30 years on buildings.

We began production activities at Fab 4 on October 31, 2003. We began to depreciate the Fab 4 assets as they were placed in service for production purposes. As of September 30, 2009, all of the buildings and supporting facilities were being depreciated as well as the manufacturing equipment that had been placed in service. All manufacturing equipment that was not being used in production activities was maintained in projects in process and is not being depreciated until it is placed into service since management believes there will be no change to its utility from the present time until it is placed into productive service. The lives to be used for depreciating this equipment at Fab 4 will be evaluated at such time as the assets are placed in service. We do not believe that the temporary idling of such assets has impaired the estimated life or carrying values of the underlying assets.

The estimates, assumptions and judgments we use in the application of our property and equipment policies reflect both historical experience and expectations regarding future industry conditions and operations. The use of different estimates, assumptions and judgments regarding the useful lives of our property and equipment and expectations regarding future industry conditions and operations, could result in materially different carrying values of assets and results of operations.

Impairment of Property, Plant and Equipment

We assess whether indicators of impairment of long-lived assets are present. If such indicators are present, we determine whether the sum of the estimated undiscounted cash flows attributable to the assets in question is less than their carrying value. If less, we recognize an impairment loss based on the excess of the carrying amount of the assets over their respective fair values. Fair value is determined by discounted future cash flows, appraisals or other methods. If the assets determined to be impaired are to be held and used, we recognize an impairment loss through a charge to our operating results to the extent the present value of anticipated net cash flows attributable to the asset are less than the asset's carrying value, which we depreciate over the remaining estimated useful life of the asset. We may incur impairment losses, or additional losses on already impaired assets, in future periods if factors influencing our estimates change.

Junior Subordinated Convertible Debentures

We separately account for the liability and equity components of our junior subordinated convertible debentures in a manner that reflects our nonconvertible debt (unsecured debt) borrowing rate when interest cost is recognized. This results in a bifurcation of a component of the debt, classification of that component in equity and the accretion of the resulting discount on the debt to be recognized as part of interest expense in our consolidated statements of operations. Additionally, certain embedded features of the debentures qualify as derivatives and are bundled as a compound embedded derivative that is measured at fair value. Lastly, we include the dilutive effect of the shares of our common stock issuable upon conversion of the outstanding junior subordinated convertible debentures in our diluted income per share calculation regardless of whether the market price trigger or other contingent conversion feature has been met. We apply the treasury stock method as we have the intent and current ability to settle the principal amount of the junior subordinated convertible debentures in cash. This method results in incremental dilutive shares when the average fair value of our common stock for a reporting period exceeds the conversion price per share which was $31.13 at September 30, 2009 and adjusts as dividends are recorded in the future.

Litigation

Our current estimated range of liability related to pending litigation is based on the probable loss of claims for which we can estimate the amount and range of loss. Recorded reserves were not significant at September 30, 2009.

Because of the uncertainties related to both the probability of loss and the amount and range of loss on our pending litigation, we are unable to make a reasonable estimate of the liability that could result from an unfavorable outcome. As additional information becomes available, we will assess the potential liability related to our pending litigation and revise our estimates. Revisions in our estimates of the potential liability could materially impact our results of operation and financial position.

Results of Operations

The following table sets forth certain operational data as a percentage of net sales for the periods indicated:

	Three Months Ended September 30,						Six Months Ended September 30,

Net Sales

We operate in one industry segment and engage primarily in the design, development, manufacture and marketing of semiconductor products. We sell our products to distributors and original equipment manufacturers, referred to as OEMs, in a broad range of market segments, perform ongoing credit evaluations of our customers and generally require no collateral. In certain circumstances, a customer's financial condition may require collateral, and, in such cases, the collateral would be provided primarily by letters of credit.

Our net sales for the quarter ended September 30, 2009 were $226.7 million, an increase of 17.5% from the previous quarter's sales of $192.9 million, and a decrease of 16.0% from net sales of $269.7 million in the quarter ended September 30, 2008. Our net sales for the six months ended September 30, 2009 were $419.6 million, a decrease of 22.0% from net sales of $537.9 million in the six months ended September 30, 2008. The increase in net sales in the quarter ended September 30, 2009 over the previous quarter was due primarily to improving semiconductor industry conditions and market share gains in our strategic product lines. The decreases in net sales for the quarter ended September 30, 2009 compared to the quarter ended September 30, 2008, and for the six months ended September 30, 2009 compared to the six months ended September 30, 2008, resulted primarily from adverse changes in global economic and end-market conditions across all of our product lines. Average selling prices for our products were down approximately 5% for the three and six-month periods ended September 30, 2009 over the corresponding periods of the previous fiscal year. The number of units of our products sold was down approximately 11% and 18% for the three and six-month periods ended September 30, 2009 over the corresponding periods of the previous fiscal year. The average selling prices and the unit volumes of our sales are impacted by the mix of our products sold and overall semiconductor market conditions. Key factors related to the amount of net sales during the three and six-month periods ended September 30, 2009 include:

adverse global economic conditions in the markets we serve;

semiconductor industry conditions;

increasing semiconductor content in our customers' products;

customers' increasing needs for the flexibility offered by our programmable solutions;

our new product offerings that have increased our served available market;

continued market share gains; and

inventory holding patterns of our customers.

Sales by product line for the three and six months ended September 30, 2009 and 2008 were as follows (dollars in thousands):

	Three Months Ended September 30, (unaudited)										Six Months Ended September 30, (unaudited)
	2009		%			2008		%			2009		%			2008		%

Microcontrollers

Our microcontroller product line represents the largest component of our total net sales. Microcontrollers and associated application development systems accounted for approximately 81.2% of our total net sales for the three-month period ended September 30, 2009 and approximately 81.5% of our total net sales for the six-month period ended September 30, 2009 compared to approximately 80.5% of our total net sales for the three-month period ended September 30, 2008 and approximately 80.8% of our total net sales for the six-month period ended September 30, 2008.

Net sales of our microcontroller products decreased approximately 15.1% in the three-month period ended September 30, 2009 and 21.3% in the six-month period ended September 30, 2009 compared to the three and six-month periods ended September 30, 2008. These sales decreases were primarily due to adverse global economic conditions in the markets we serve and the other factors described above. The end markets that we serve include the consumer, automotive, industrial control, communications and computing markets.

Historically, average selling prices in the semiconductor industry decrease over the life of any particular product. The overall average selling prices of our microcontroller products have remained relatively constant over time due to the proprietary nature of these products. We have experienced, and expect to continue to experience pricing pressure in certain microcontroller product lines, primarily due to competitive conditions. We have been able in the past, and expect to be able in the future, to moderate average selling price declines in our microcontroller product lines by introducing new products with more features and higher prices. We may be unable to maintain average selling prices for our microcontroller products as a result of increased pricing pressure in the future, which would adversely affect our operating results.

Memory Products

Sales of our memory products accounted for approximately 8.5% of our total net sales for the three and six-month periods ended September 30, 2009 compared to approximately 10.3% of our total net sales for the three-month period ended September 30, 2008 and 10.5% of our total net sales in the six-month period ended September 30, 2008.

Net sales of our memory products decreased approximately 30.8% in the three-month period ended September 30, 2009 and 36.4% in the six-month period ended September 30, 2009 compared to the three and six-month periods ended September 30, 2008. These sales decreases were driven primarily by adverse global economic conditions and by customer demand conditions within the Serial EEPROM market which products comprise substantially all of our memory product net sales.

Serial EEPROM product pricing has historically been cyclical in nature, with steep price declines followed by periods of relative price stability, driven by changes in industry capacity at different stages of the business cycle. We have experienced, and expect to continue to experience, varying degrees of competitive pricing pressures in our Serial EEPROM products. We may be unable to maintain the average selling prices of our Serial EEPROM products as a result of increased pricing pressure in the future, which could adversely affect our operating results.

Analog and Interface Products

Sales of our analog and interface products accounted for approximately 10.3% of our total net sales for the three-month period ended September 30, 2009 and 10.0% of our total net sales for the six-month period ended September 30, 2009 compared to approximately 9.2% of our total net sales for the three-month period ended September 30, 2008 and 8.7% of our total net sales for the six-month period ended September 30, 2008.

Net sales of our analog and interface products decreased approximately 6.1% in the three-month period ended September 30, 2009 and 10.9% in the six-month period ended September 30, 2009 compared to the three and six-month periods ended September 30, 2008. These sales decreases were driven primarily by adverse global economic conditions which offset market share gains achieved within the analog and interface market.

Analog and interface products can be proprietary or non-proprietary in nature. Currently, we consider more than half of our analog and interface product mix to be proprietary in nature, where prices are relatively stable, similar to the pricing stability experienced in our microcontroller products. The non-proprietary portion of our analog and interface business will experience price fluctuations, driven primarily by the current supply and demand for those products. We may be unable to maintain the average selling prices of our analog and interface products as a result of increased pricing pressure in the future, which would adversely affect our operating results. We anticipate the proprietary portion of our analog and interface products will continue to increase over time.

Distribution

Distributors accounted for approximately 61% of our net sales in the three-month period ended September 30, 2009 and approximately 63% of our net sales in the three-month period ended September 30, 2008. Distributors accounted for approximately 62% of our net sales in the six-month period ended September 30, 2009 and approximately 63% of our net sales in the six-month period ended September 30, 2008.

Our largest distributor accounted for approximately 12% of our net sales in the three and six-month periods ended September 30, 2009 and approximately 13% of our net sales in the three and six-month periods ended September 30, 2008.

Generally, we do not have long-term agreements with our distributors and we, or our distributors, may terminate our relationships with each other with little or no advanced notice. The loss of, or the disruption in the operations of, one or more of our distributors could reduce our future net sales in a given quarter and could result in an increase in inventory returns.

At September 30, 2009, our distributors maintained 35 days of inventory of our products which is in line with their inventory levels at March 31, 2009. Over the past three fiscal years, the days of inventory maintained by our distributors have fluctuated between 31 days and 42 days. We do not believe that inventory holding patterns at our distributors will materially impact our net sales, due to the fact that we recognize revenue based on sell-through for all our distributors.

Sales by Geography

Sales by geography for the three and six-month periods ended September 30, 2009 and 2008 were as follows (dollars in thousands):

	Three Months Ended September 30, (unaudited)										Six Months Ended September 30, (unaudited)
	2009		%			2008		%			2009		%			2008		%
Americas	$	55,892		24.7	%	$	64,623		24.0	%	$	105,367		25.1	%	$	130,751		24.3	%
Europe		54,482		24.0			73,167		27.1			104,003		24.8			151,153		28.1
Asia		116,287		51.3			131,916		48.9			210,240		50.1			255,974		47.6
Total sales	$	226,661		100.0	%	$	269,706		100.0	%	$	419,610		100.0	%	$	537,878		100.0	%

Our sales to foreign customers have been predominately in Asia and Europe, which we attribute to the manufacturing strength in those areas for automotive, communications, computing, consumer and industrial control products. Americas sales include sales to customers in the U.S., Canada, Central America and South America.

Sales to foreign customers accounted for approximately 78% and 77% of our net sales in the three and six-month periods ended September 30, 2009, respectively, compared to 76% in each of the three and six-month periods ended September 30, 2008. Substantially all of our foreign sales are U.S. dollar denominated. Sales to customers in Asia have generally increased over time due to many of our customers transitioning their manufacturing operations to Asia and growth in demand from the emerging Asian market. Our sales force in the Americas and Europe supports a significant portion of the design activity for products which are ultimately shipped to Asia.

Gross Profit

Our gross profit was $123.3 million in the three months ended September 30, 2009 and $164.2 million in the three months ended September 30, 2008. Our gross profit was $219.8 million in the six months ended September 30, 2009 and $327.8 million in the six months ended September 30, 2008. Gross profit as a percentage of sales was 54.4% in the three months ended September 30, 2009 and 60.9% in the three months ended September 30, 2008. Gross profit as a percentage of sales was 52.4% in the six months ended September 30, 2009 and 60.9% in the six months ended September 30, 2008.

The most significant factors affecting our gross profit percentage in the periods covered by this Quarterly Report on Form 10-Q were:

production levels being below the range of our normal capacity resulting in under absorption of fixed costs; and

inventory write-downs partially offset by sales of inventory that was previously written down.

Other factors that impacted gross profit percentage in the periods covered by this Quarterly Report on Form 10-Q include:

lower depreciation as a percentage of cost of sales;

fluctuations in the product mix of microcontrollers, proprietary and non-proprietary analog products and Serial EEPROM products resulting in lower overall average selling prices for our products; and

continual cost reductions in wafer fabrication and assembly and test manufacturing, such as new manufacturing technologies and more efficient manufacturing techniques.

During the three-month period ended September 30, 2009, we operated at approximately 68% of our combined Fab 2 and Fab 4 installed capacity, compared to approximately 99% for the three-month period ended September 30, 2008. During the third and fourth quarters of fiscal 2009, we reduced wafer starts at both Fab 2 and Fab 4 and implemented rotating unpaid time off at both fabrication facilities. The reduction in wafer starts and rotating unpaid time off were implemented to help control inventory levels due to adverse economic conditions in the markets we serve. Reduced levels of production continued through the second quarter of fiscal 2010, however, we did begin to increase production output from our wafer fabs in the second quarter of fiscal 2010 to support increasing demand for our products. During the third quarter of fiscal 2010, we expect our wafer fabs to continue to operate at levels which are lower than peak levels.

As a result of significant reductions in demand and decreased production in our wafer fabs, approximately $8.5 million and $20.6 million was charged to cost of sales in the three and six-month periods ended September 30, 2009, as our production levels for the periods were below the range of normal capacity. There were no such charges in the three and six-month periods ended September 30, 2008. If production levels stay below our normal capacity, we will continue to charge cost of sales for the unabsorbed capacity.

The process technologies utilized impact our gross margins. Fab 2 currently utilizes various manufacturing process technologies, but predominantly utilizes our 0.5 to 1.0 micron processes. Fab 4 predominantly utilizes our 0.22 to 0.5 micron processes. We continue to transition products to more advanced process technologies to reduce future manufacturing costs. All of our production has been on 8-inch wafers for the periods covered by this report.

Our overall inventory levels were $108.5 million at September 30, 2009 compared to $131.5 million at March 31, 2009. We had 96 days of inventory on our balance sheet at September 30, 2009 compared to 134 days at March 31, 2009 and 110 days at September 30, 2008. The reduction of our inventory levels was a result of increased net sales and our efforts to manage inventory through production cuts.

We anticipate that our gross margins will fluctuate over time, driven primarily by capacity utilization levels, the overall product mix of microcontroller, analog and interface and memory products and the percentage of net sales of each of these products in a particular quarter, as well as manufacturing yields, fixed cost absorption, and competitive and economic conditions in the markets we serve.

At September 30, 2009, approximately 67% of our assembly requirements were being performed in our Thailand facility, compared to approximately 68% at September 30, 2008. Third-party contractors located in Asia perform the balance of our assembly operations. Substantially all of our test requirements were being performed in our Thailand facility as of September 30, 2009 and September 30, 2008. We believe that the assembly and test operations performed at our Thailand facility provide us with significant cost savings when compared to contractor assembly and test costs, as well as increased control over these portions of the manufacturing process.

We rely on outside wafer foundries for a portion of our wafer fabrication requirements.

Our use of third parties involves some reduction in our level of control over the portions of our business that we subcontract. While we review the quality, delivery and cost performance of our third-party contractors, our future operating results could suffer if any third-party contractor is unable to maintain manufacturing yields, assembly and test yields and costs at approximately their current levels.

Research and Development (R&D)

R&D expenses for the three months ended September 30, 2009 were $29.6 million, or 13.0% of net sales, compared to $31.3 million, or 11.7% of net sales, for the three months ended September 30, 2008. R&D expenses for the six months ended September 30, 2009 were $57.2 million, or 13.6% of net sales, compared to $62.9 million, or 11.7% of net sales for the six months ended September 30, 2008. We are committed to investing in new and enhanced products, including development systems software, and in our design and manufacturing process technologies. We believe these investments are significant factors in maintaining our competitive position. R&D costs are expensed as incurred. Assets purchased to support our ongoing research and development activities are capitalized when related to products which have achieved technological feasibility or that have alternative future uses and are amortized over their expected useful lives. R&D expenses include labor, depreciation, masks, prototype wafers, and expenses for the development of process technologies, new packages, and software to support new products and design environments.

R&D expenses decreased $1.8 million, or 5.7%, for the three months ended September 30, 2009 over the same period last year. R&D expenses decreased $5.7 million, or 9.0%, for the six months ended September 30, 2009 over the same period last year. The primary reasons for the dollar decreases in R&D costs over these periods were cost-cutting actions that began in the second half of fiscal 2009, including broad-based reductions in salary and other compensation levels, lower travel costs, and reductions in other variable expenses.

Selling, General and Administrative

Selling, general and administrative expenses for the three months ended September 30, 2009 were $41.0 million, or 18.1% of net sales, compared to $45.6 million, or 16.9% of net sales, for the three months ended September 30, 2008. Selling, general and administrative expenses for the six months ended September 30, 2009 were $77.4 million, or 18.5% of net sales, compared to $91.0 million, or 16.9% of net sales, for the six months ended September 30, 2008. Selling, general and administrative expenses include salary and other expenses related to field sales, marketing and administrative personnel, advertising and promotional expenditures and legal expenses. Selling, general and administrative expenses also include costs related to our direct sales force and FAEs who work in sales offices worldwide to stimulate demand by assisting customers in the selection and use of our products.

Selling, general and administrative expenses decreased $4.6 million, or 10.0%, for the three months ended September 30, 2009 over the same period last year. Selling, general and administrative expenses decreased $13.6 million, or 15.0%, for the six months ended September 30, 2009 over the same period last year. The primary reasons for the dollar decreases in selling, general and administrative costs over these periods were cost-cutting actions that began in the second half of fiscal 2009, including broad-based reductions in salary and other compensation levels, lower travel costs, and reductions in other variable expenses.

Special Charge

During the June 2009 quarter we agreed to the terms of a patent license with an unrelated third-party and signed an agreement on July 9, 2009. The patent license settled alleged infringement claims. The total payment made to the third-party in July 2009 was $1.4 million, $1.2 million of which was expensed in the first quarter of fiscal 2010 and the remaining $0.2 million was recorded as a prepaid royalty that will be amortized over the remaining life of the patent, which expires June 2010.

Other Income (Expense)

Interest income in the three-month period ended September 30, 2009 decreased to $4.5 million from $10.2 million in the three-month period ended September 30, 2008. Interest income in the six-month period ended September 30, 2009 decreased to $7.8 from $20.4 million in the six-month period ended September 30, 2008. The primary reason for the reductions in interest income was lower interest rates applying to our invested

cash balances in the three and six-month periods ended September 30, 2009 compared to the prior year periods. Interest expense related to our 2.125% junior subordinated convertible debentures in the three and six-month periods ended September 30, 2009 was $8.0 million and $15.5 million, respectively, compared to $6.9 million and $14.5 million, respectively, in the three and six-month periods ended September 30, 2008. Other income, net in the three-month period ended September 30, 2009 was $2.1 million compared to other income, net of $1.7 million in the three-month period ended September 30, 2008. Other income, net in the six-month period ended September 30, 2009 was $7.8 million compared to other income, net of $4.4 million in the six-month period ended September 30, 2008. The increase in other income, net in the three-month period ended September 30, 2009 over the same period last year primarily relates to foreign currency fluctuations. The increase in other income, net in the six-month period ended September 30, 2009 over the same period last year primarily relates to a $7.5 million gain on trading securities during the six months ended September 30, 2009 as a result of market fluctuations in the value of our trading securities and put options and sales of trading securities as described in Note 4 to our condensed consolidated financial statements.

Provision for Income Taxes

The provision for income taxes reflects tax on foreign earnings and federal and state tax on U.S. earnings. We had an effective tax rate of 13.3% for the three-month period ended September 30, 2009, 14.4% for the six-month period ended September 30, 2009 and 17.8% for each of the three and six-month periods ended September 30, 2008. Our effective tax rate for the first six months of fiscal 2010 was lower than our effective tax rate for the first six months of fiscal 2009 primarily due to a favorable clarification of tax regulations. Our effective tax rate is lower than statutory rates in the U.S. primarily due to our mix of earnings in foreign jurisdictions with lower tax rates.

Various taxing authorities in the U.S. and other countries in which we do business are increasing their scrutiny of the tax structures employed by businesses. Companies of our size and complexity are regularly audited by the taxing authorities in the jurisdictions in which they conduct significant operations. We are currently under audit by the IRS for our fiscal years ended March 31, 2002, 2003, 2004, 2006, 2007 and 2008. We recognize liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional tax payments are probable. We believe that we maintain adequate tax reserves to offset any potential tax liabilities that may arise upon these and other pending audits in the U.S. and other countries in which we do business. If such amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary. If such amounts ultimately prove to be less than any final assessment, a future charge to expense would be recorded in the period in which the assessment is determined.

Our Thailand manufacturing operations currently benefit from numerous tax holidays that have been granted to us by the Thailand government based on our investments in property, plant and equipment in Thailand. Our tax holiday periods in Thailand expire at various times in the future. Any expiration of our tax holidays is expected to have a minimal impact on our overall tax expense due to other tax holidays and an increase in income in other taxing jurisdictions with lower statutory rates.

Liquidity and Capital Resources

We had $1,472.7 million in cash, cash equivalents and short-term and long-term investments at September 30, 2009, an increase of $32.0 million from the March 31, 2009 balance. The increase in cash, cash equivalents and short-term and long-term investments over this time period is primarily attributable to cash generated from operating activities being offset by dividend payments in the six months ended September 30, 2009.

Net cash provided from operating activities was $243.1 million for the six-month period ended September 30, 2009 compared to $267.5 million for the six-month period ended September 30, 2008. The decrease in cash flow from operations in the six-month period ended September 30, 2009 compared to the six-month period ended September 30, 2008 was primarily due to lower net income in the six-month period ended September 30, 2009, and increases in accounts receivable. These decreases in cash flows were offset primarily by sales of trading securities, which provided approximately $87.0 million of operating cash flow in the six-month period ended September 30, 2009, as compared to sales and purchases of trading securities which used $15.9 million of operating cash flow in the six months ended September 30, 2008.

During the six months ended September 30, 2009, net cash used in investing activities was $34.0 million. During the six months ended September 30, 2008, net cash used in investing activities was $230.4 million. The decrease in net cash used in investing activities was primarily due to changes in our net purchases, sales and maturities of short-term and long-term investments and higher capital expenditures in the six-month period ended September 30, 2008.

Net cash used in financing activities was $114.4 million for the six months ended September 30, 2009 compared to net cash used in financing activities of $213.1 million for the six months ended September 30, 2008. Proceeds from the exercise of stock options and employee purchases under our employee stock purchase plans were $9.0 million for the six months ended September 30, 2009 and $25.5 million for the six months ended September 30, 2008. We paid cash dividends to our shareholders of $124.1 million in the six months ended September 30, 2009 and $123.1 million in the six months ended September 30, 2008. We did not repurchase any of our shares of common stock during the six months ended September 30, 2009. We purchased 4.0 million shares of our common stock for $123.9 million during the six months ended September 30, 2008. Excess tax benefits from share-based payment arrangements were $0.7 million in the six months ended September 30, 2009. Excess tax benefits from share-based payment arrangements were $8.6 million in the six months ended September 30, 2008.

Our level of capital expenditures varies from time to time as a result of actual and anticipated business conditions. Capital expenditures in the six months ended September 30, 2009 were $9.7 million compared to $68.0 million for the six months ended September 30, 2008. Capital expenditures are primarily for the expansion of production capacity and the addition of research and development equipment. We currently intend to spend approximately $40 million during the next twelve months to invest in equipment and facilities to maintain, and selectively increase, capacity to meet our currently anticipated needs.

We expect to finance capital expenditures through our existing cash balances and cash flows from operations. We believe that the capital expenditures anticipated to be incurred over the next twelve months will provide sufficient manufacturing capacity to meet our currently anticipated needs.

We enter into derivative transactions from time to time in an attempt to reduce our exposure to currency rate fluctuations. Although none of the countries in which we conduct significant foreign operations has had a highly inflationary economy in the last five years, there is no assurance that inflation rates or fluctuations in foreign currency rates in countries where we conduct operations will not adversely affect our operating results in the future. At September 30, 2009, we had no foreign currency forward contracts outstanding.

On December 11, 2007, we announced that our Board of Directors had authorized the repurchase of up to an additional 10.0 million shares of our common stock in the open market or in privately negotiated transactions. As of September 30, 2009, we had repurchased 7.5 million shares under this 10.0 million share authorization for a total of $234.7 million. There is no expiration date associated with this program. The timing and amount of future repurchases will depend upon market conditions, interest rates, and corporate considerations.

As of September 30, 2009, we held approximately 35.2 million shares as treasury shares.

On October 28, 2002, we announced that our Board of Directors had approved and instituted a quarterly cash dividend on our common stock. A quarterly dividend of $0.339 per share was paid on September 3, 2009 in the aggregate amount of $62.1 million. A quarterly dividend of $0.34 per share was declared on November 4, 2009 and will be paid on December 2, 2009 to stockholders of record as of November 18, 2009. We expect the aggregate December 2009 cash dividend to be approximately $62.3 million. Our Board of Directors is free to change our dividend practices at any time and to increase or decrease the dividend paid, or not to pay a dividend on our common stock on the basis of our results of operations, financial condition, cash requirements and future prospects, and other factors deemed relevant by our Board of Directors. Our current intent is to provide for ongoing quarterly cash dividends depending upon market conditions and our results of operations.

We believe that our existing sources of liquidity combined with cash generated from operations will be sufficient to meet our currently anticipated cash requirements for at least the next 12 months. However, the

semiconductor industry is capital intensive. In order to remain competitive, we must constantly evaluate the need to make significant investments in capital equipment for both production and research and development. We may seek additional equity or debt financing from time to time to maintain or expand our wafer fabrication and product assembly and test facilities, or for acquisitions or other purposes. The timing and amount of any such financing requirements will depend on a number of factors, including demand for our products, changes in industry conditions, product mix, competitive factors and our ability to identify suitable acquisition candidates. There can be no assurance that such financing will be available on acceptable terms, and any additional equity financing would result in incremental ownership dilution to our existing stockholders.

Contractual Obligations

There have not been any material changes in our contractual obligations from what we disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2009.

Off-Balance Sheet Arrangements

As of September 30, 2009, we are not involved in any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Recently Issued Accounting Pronouncements

For a description of recently issued accounting pronouncements, refer to Note 2 of the Notes to Condensed Consolidated Financial Statements.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk

Our investment portfolio, consisting of fixed income securities, money market funds, and cash deposits that we hold on an available-for-sale basis, was $1,442.2 million as of September 30, 2009 compared to $1,367.0 million as of June 30, 2009, and our trading securities totaled $4,000 as of September 30, 2009 compared to $71.1 million as of June 30, 2009. The available-for-sale securities, like all fixed income instruments, are subject to interest rate risk and will decline in value if market interest rates increase. We have the ability to hold our fixed income investments until maturity and, therefore, we would not expect to recognize any material adverse impact in income or cash flows if market interest rates increase.

At September 30, 2009, $45.3 million of original purchase value of our investment portfolio was invested in ARS. Historically, the carrying value of ARS approximated due to the frequent resetting of the interest rates. If an auction fails for amounts we have invested, our investment will not be liquid. With the continuing liquidity issues experienced in the global credit and capital markets, our ARS have experienced multiple failed auctions. In September 2007 and February 2008, auctions for $24.9 million and $34.8 million, respectively, of the original purchase value of our investments in ARS had failed. While we continue to earn interest on these investments based on a pre-determined formula with spreads tied to particular interest rate indices, the estimated market value for a portion of these ARS no longer approximates the original purchase value.

At September 30, 2009, the $24.9 million of ARS that failed during September 2007 carried ratings between A- and CC by Standard & Poors compared to ratings between A- and B at June 30, 2009. All but $2.5 million of the securities possess credit enhancement in the form of insurance for principal and interest. The underlying characteristics of $22.4 million of these ARS relate to servicing statutory requirements in the life insurance industry and $2.5 million relate to a specialty finance company. Subsequent to our investment in these ARS, the ARS have experienced multiple rating downgrades by the major rating agencies. All such rating change actions have been factored into the fair value estimates of the ARS for the period ending September 30, 2009.

The $24.9 million in failed auctions have continued to fail through the filing date of this Quarterly Report on Form 10-Q. As a result, we will not be able to access such funds until a future auction on these investments is successful. The fair value of the failed ARS has been estimated based on market information and estimates determined by management and could change significantly based on market conditions. We evaluated the impairments in the value of these ARS, determining our intent to sell these securities prior to the recovery of our amortized cost basis resulted in the securities being other-than-temporarily impaired and have recognized an impairment charge on these investments of $0.4 million and $1.3 million, respectively, in the quarters ended September 30, 2009 and June 30, 2009.

In November 2008, we executed an ARS rights agreement (the Rights) with the broker through which we purchased the $30.5 million in ARS that provides (1) us with the right to put these ARS back to the broker at par anytime during the period from June 30, 2010 through July 2, 2012, and (2) the broker with the right to purchase or sell the ARS at par on our behalf anytime through July 2, 2012. We accounted for the acceptance of the Rights as the receipt of a put option for no consideration and recognized a gain with a corresponding recognition as a long-term investment. We elected to measure the Rights at fair value and will record changes in the fair value of the Rights in earnings, as the Rights do not provide for net settlement and therefore are not otherwise marked to fair value as derivatives. We simultaneously recognized an other-than-temporary impairment loss of $5.5 million as we no longer intend to hold these ARS until the fair value recovers, which was recorded in other comprehensive loss in prior quarters. We have reclassified the ARS from available-for-sale to trading securities and future changes in fair value are being recorded in earnings. During the second quarter of fiscal 2010, we estimated the fair value of the ARS increased by $1.3 million offset by a change in the fair value of the related Rights of $1.3 million, with no net impact to our income statement. We expect any future changes in the fair value of the ARS to be largely offset by changes in the fair value of the related Rights without any significant net impact to our income statement. We will continue to measure the ARS and the Rights at fair value (utilizing Level 3 inputs) until the earlier of its maturity or exercise.

We continue to monitor the market for ARS and consider its impact, if any, on the fair market value of our investments. If the market conditions deteriorate further, we may be required to record additional impairment charges. We intend to sell the $24.9 million of ARS. We intend and have the ability to hold the $30.5 million of ARS until June 30, 2010 when we have the right to sell the auction rates at par to the broker. We do not anticipate having to sell these securities to fund the operations of our business. We believe that, based on our current unrestricted cash, cash equivalents and short-term investment balances, the current lack of liquidity in the credit markets will not have a material impact on our liquidity, cash flow or ability to fund our operations.

Our investment in marketable equity securities at September 30, 2009 consists of shares of common stock, the value of which is determined by the closing price of such shares on the respective markets on which the shares are traded as of the balance sheet date. These investments are classified as trading securities and measured at fair value with changes in that fair value recorded in income. The market value of these investments was approximately $4,000 at September 30, 2009 compared to our cost basis of approximately $5,000. Based on the limited investment in marketable equity securities at September 30, 2009, the value of our investment in marketable equity securities would not be materially impacted if there were a significant change in the market price of the shares. (See Note 4 to our condensed consolidated financial statements for additional information about our investments in marketable equity securities.)

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, as required by paragraph (b) of Rule 13a-15 or Rule 15d-15 under the Securities Exchange Act of 1934, as amended, we evaluated under the

supervision of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended). Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 (i) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and (ii) is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our disclosure control and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management. Our disclosure controls and procedures include components of our internal control over financial reporting. Management's assessment of the effectiveness of our internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute, assurance that the control system's objectives will be met.

Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2009, there was no change in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II. OTHER INFORMATION

Item 1.

Legal Proceedings

In the ordinary course of our business, we are involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. We also periodically receive notifications from various third parties alleging infringement of patents, intellectual property rights or other matters. With respect to pending legal actions to which we are a party, although the outcome of these actions is not presently determinable, we believe that the ultimate resolution of these matters will not harm our business and will not have a material adverse effect on our financial position, cash flows or results of operations. Litigation relating to the semiconductor industry is not uncommon, and we are, and from time to time have been, subject to such litigation. No assurances can be given with respect to the extent or outcome of any such litigation in the future.

Item 1A.

Risk Factors

When evaluating Microchip and its business, you should give careful consideration to the factors listed below, in addition to the information provided elsewhere in this Form 10-Q and in other documents that we file with the Securities and Exchange Commission.

Our operating results have been adversely impacted by global economic conditions and may fluctuate due to a number of other factors that could reduce our net sales and profitability.

Our operating results are affected by a wide variety of factors that could reduce our net sales and profitability, many of which are beyond our control. Some of the factors that may affect our operating results include:

changes in demand or market acceptance of our products and products of our customers;

levels of inventories at our customers;

the mix of inventory we hold and our ability to satisfy orders from our inventory;

changes in utilization of our manufacturing capacity and fluctuations in manufacturing yields;

our ability to secure sufficient assembly and testing capacity;

availability of raw materials and equipment;

competitive developments including pricing pressures;

the level of orders that are received and can be shipped in a quarter;

the level of sell-through of our products through distribution;

fluctuations in the mix of products;

changes or fluctuations in customer order patterns and seasonality;

constrained availability from other electronic suppliers impacting our customers' ability to ship their products, which in turn may adversely impact our sales to those customers;

costs and outcomes of any current or future tax audits or any litigation involving intellectual property, customers or other issues;

changes in tax regulations and policies in the U.S. and other countries in which we do business;

disruptions in our business or our customers' businesses due to terrorist activity, armed conflict, war, worldwide oil prices and supply, public health concerns or disruptions in the transportation system;

fluctuations in commodity prices;

property damage or other losses, whether or not covered by insurance; and

general economic, industry or political conditions in the U.S. or internationally.

We believe that period-to-period comparisons of our operating results are not necessarily meaningful and that you should not rely upon any such comparisons as indications of future performance. In future periods our operating results may fall below our public guidance or the expectations of public market analysts and investors, which would likely have a negative effect on the price of our common stock. Adverse global economic conditions have adversely impacted our operating results and make comparability between periods less meaningful.

Our operating results will suffer if we ineffectively utilize our manufacturing capacity or fail to maintain manufacturing yields.

The manufacture and assembly of integrated circuits, particularly non-volatile, erasable CMOS memory and logic devices such as those that we produce, are complex processes. These processes are sensitive to a wide variety of factors, including the level of contaminants in the manufacturing environment, impurities in the materials used, the performance of our wafer fabrication personnel and equipment, and other quality issues. As is typical in the semiconductor industry, we have from time to time experienced lower than anticipated manufacturing yields. Our operating results will suffer if we are unable to maintain yields at approximately the current levels. This could include delays in the recognition of revenue, loss of revenue or future orders, and customer-imposed penalties for failure to meet contractual shipment deadlines. Our operating results are also adversely affected when we operate at less than optimal capacity. In the quarter ended March 31, 2009, we reduced wafer starts in both Fab 2 and Fab 4, implemented rotating unpaid time off and had multiple planned shutdowns in our Thailand facility. These actions were implemented to help control inventory levels in response to adverse economic conditions. This lower capacity utilization resulted in certain costs being charged directly to expense and lower gross margins. In the quarter ended September 30, 2009, we increased our production output in our factories and did not have any shutdowns in our Thailand operation and reduced the amount of rotating unpaid time off in Fab 2 and Fab 4. We are unable to predict when we will be able to return to more optimal levels of capacity utilization.

We are dependent on orders that are received and shipped in the same quarter and are therefore limited in our visibility of future product shipments.

Our net sales in any given quarter depend upon a combination of shipments from backlog and orders received in that quarter for shipment in that quarter, which we refer to as turns orders. We measure turns orders at the beginning of a quarter based on the orders needed to meet the shipment targets that we set entering the quarter. Historically, we have relied on our ability to respond quickly to customer orders as part of our competitive strategy, resulting in customers placing orders with relatively short delivery schedules. Shorter lead times generally mean that turns orders as a percentage of our business are relatively high in any particular quarter and reduce our backlog visibility on future product shipments. Turns orders correlate to overall semiconductor industry conditions and product lead times. Because turns orders are difficult to predict, varying levels of turns orders make our net sales more difficult to forecast. If we do not achieve a sufficient level of turns orders in a particular quarter relative to our revenue targets, our revenue and operating results may suffer.

Intense competition in the markets we serve may lead to pricing pressures, reduced sales of our products or reduced market share.

The semiconductor industry is intensely competitive and has been characterized by price erosion and rapid technological change. We compete with major domestic and international semiconductor companies, many of which have greater market recognition and substantially greater financial, technical, marketing, distribution and other resources than we do. We may be unable to compete successfully in the future, which could harm our business. Our ability to compete successfully depends on a number of factors both within and outside our control, including, but not limited to:

the quality, performance, reliability, features, ease of use, pricing and diversity of our products;

our success in designing and manufacturing new products including those implementing new technologies;

the rate at which customers incorporate our products into their own applications;

product introductions by our competitors;

the number, nature and success of our competitors in a given market;

our ability to obtain adequate supplies of raw materials and other supplies at acceptable prices;

our ability to protect our products and processes by effective utilization of intellectual property rights;

our ability to address the needs of our customers; and

general market and economic conditions.

Historically, average selling prices in the semiconductor industry decrease over the life of any particular product. The overall average selling prices of our microcontroller and proprietary analog and interface products have remained relatively constant, while average selling prices of our Serial EEPROM and non-proprietary analog and interface products have declined over time.

We have experienced, and expect to continue to experience, modest pricing declines in certain of our more mature proprietary product lines, primarily due to competitive conditions. We have been able to moderate average selling price declines in many of our proprietary product lines by continuing to introduce new products with more features and higher prices. However, there can be no assurance that we will be able to do so in the future. We have experienced in the past, and expect to continue to experience in the future, varying degrees of competitive pricing pressures in our Serial EEPROM and non-proprietary analog products. We may be unable to maintain average selling prices for our products as a result of increased pricing pressure in the future, which could adversely impact our operating results.

Our business is dependent on selling through distributors.

Sales through distributors accounted for approximately 64% of our net sales in fiscal 2009 and approximately 62% of our net sales in the first six months of fiscal 2010. Our largest distributor accounted for approximately 14% of our net sales in fiscal 2009 and approximately 12% of our net sales in the first six months of fiscal 2010. We do not have long-term agreements with our distributors and we and our distributors may each terminate our relationship with little or no advance notice.

Continued adverse conditions in the U.S. and global economies and in the U.S. and global credit markets could materially impact the operations of our distributors. Any deterioration in the financial condition of our distributors or any disruption in the operations of our distributors could adversely impact the flow of our products to our end customers and adversely impact our results of operation. In addition, during an industry and/or economic downturn, such as the current recession, it is possible there will be an oversupply of products and a decrease in sell-through of our products by our distributors which could reduce our net sales in a given period and result in an increase in inventory returns.

Recent credit and equity market conditions have adversely impacted our holdings of auction rate securities, investments and trading securities which has had a material adverse impact on our results of operations.

At September 30, 2009, $45.3 million of the fair value of our investment portfolio was invested in ARS. Historically, the carrying value of ARS approximated fair value due to the frequent resetting of the interest rates. With the continuing liquidity issues in the global credit markets, our ARS have experienced multiple failed auctions. As a result, we will not be able to access such funds until a future auction on these investments is successful. In November 2008, we executed an ARS rights agreement (the Rights) with the broker through which we purchased the $31.9 million in ARS that provides (1) us with the right to put these ARS back to the broker at par anytime during the period from June 30, 2010 through July 2, 2012, and (2) the broker with the right to purchase or sell the ARS at par on our behalf anytime through July 2, 2012. We accounted for the acceptance of the Rights as the receipt of a put option for no consideration and recognized a gain with a corresponding recognition as a long-term investment. We will record changes in the fair value of the Rights in earnings, as the Rights do not provide for net settlement and therefore are not otherwise marked to fair value as derivatives. We simultaneously recognized an other-than-temporary impairment loss of $5.5 million as we no longer intend to hold the ARS to a time where the fair value recovers, which was recorded in other comprehensive loss in prior quarters. We have reclassified the ARS from available-for-sale to trading securities and future changes in fair value will be recorded in earnings. We expect any future changes in the fair value of the ARS to be largely offset by changes in the fair value of the related Rights without any significant net impact to our income statement. We will continue to measure the ARS and the Rights at fair value (utilizing Level 3 inputs) until the earlier of its maturity or exercise.

The fair value of the failed ARS has been estimated based on market information and estimates determined by management and could change significantly based on market conditions. Based on the estimated values, we concluded these investments were other than temporarily impaired and recognized an impairment charge on these investments of $0.4 million and $1.3 million, respectively, in the quarters ended September 30, 2009 and June 30, 2009. If the issuers are unable to successfully close future auctions or if their credit ratings deteriorate further, we may be required to further adjust the carrying value of the investments through an additional impairment charge to earnings.

The substantial majority of our short and long-term investments are in highly rated government agency bonds and municipal bonds. Other than with respect to our holdings of ARS, we have not experienced any liquidity or impairment issues with such investments. However, the credit markets have continued to be highly volatile and there can be no assurance that these conditions will not in the future adversely affect the liquidity or value of our investments in government agency bonds or municipal bonds.

Our success depends on our ability to introduce new products on a timely basis.

Our future operating results will depend on our ability to develop and introduce new products on a timely basis that can compete effectively on the basis of price and performance and which address customer requirements. The success of our new product introductions depends on various factors, including, but not limited to:

proper new product selection;

timely completion and introduction of new product designs;

availability of development and support tools and collateral literature that make complex new products easy for engineers to understand and use; and

market acceptance of our customers' end products.

Because our products are complex, we have experienced delays from time to time in completing development of new products. In addition, our new products may not receive or maintain substantial market acceptance. We may be unable to design, develop and introduce competitive products on a timely basis, which could adversely impact our future operating results.

Our success also depends upon our ability to develop and implement new design and process technologies. Semiconductor design and process technologies are subject to rapid technological change and

require significant R&D expenditures. We and other companies in the industry have, from time to time, experienced difficulties in effecting transitions to advanced process technologies and, consequently, have suffered reduced manufacturing yields or delays in product deliveries. Our future operating results could be adversely affected if any transition to future process technologies is substantially delayed or inefficiently implemented.

We must attract and retain qualified personnel to be successful and competition for qualified personnel can be intense.

Our success depends upon the efforts and abilities of our senior management, engineering and other personnel. The competition for qualified engineering and management personnel can be intense.

We may be unsuccessful in retaining our existing key personnel or in attracting and retaining additional key personnel that we require. The loss of the services of one or more of our key personnel or the inability to add key personnel could harm our business. We have no employment agreements with any member of our senior management team.

We are dependent on several contractors to perform key manufacturing functions for us.

We use several contractors located in Asia for a portion of the assembly and testing of our products. We also rely on outside wafer foundries for a portion of our wafer fabrication. Although we own the majority of our manufacturing resources, the disruption or termination of any of our contractors could harm our business and operating results.

Our use of third parties involves some reduction in our level of control over the portions of our business that we subcontract. Our future operating results could suffer if any contractor were to experience financial, operations or production difficulties or situations when demand exceeds capacity, or if they were unable to maintain manufacturing yields, assembly and test yields and costs at approximately their current levels, or if due to their locations in foreign countries they were to experience political upheaval or infrastructure disruption. Further, procurement of required products and services from third parties is done by purchase order and contracts. If these third parties are unable or unwilling to timely deliver products or services conforming to our quality standards, we may not be able to qualify additional manufacturing sources for our products in a timely manner or at all, and such arrangements, if any, may not be on favorable terms to us. In such event, we could experience an interruption in production, an increase in manufacturing and production costs, decline in product reliability, and our business and operating results could be adversely affected.

We may lose sales if our suppliers of raw materials and equipment fail to meet our needs.

Our semiconductor manufacturing operations require raw materials and equipment that must meet exacting standards. We generally have more than one source for these supplies, but there are only a limited number of suppliers capable of delivering various raw materials and equipment that meet our standards. The raw materials and equipment necessary for our business could become more difficult to obtain as worldwide use of semiconductors in product applications increases. We have experienced supply shortages from time to time in the past, and on occasion our suppliers have told us they need more time than expected to fill our orders or that they will no longer support certain equipment with updates or spare and replacement parts. An interruption of any raw materials or equipment sources, or the lack of supplier support for a particular piece of equipment, could harm our business.

Our operating results may be impacted by both seasonality and the wide fluctuations of supply and demand in the semiconductor industry.

The semiconductor industry is characterized by seasonality and wide fluctuations of supply and demand. Since a significant portion of our revenue is from consumer markets and international sales, our business may be subject to seasonally lower revenues in the third and fourth quarters of our fiscal year. However, fluctuations in our overall business in certain recent periods, semiconductor industry conditions and adverse global economic conditions have had a more significant impact on our results than seasonality, and have made it difficult to assess the impact of seasonal factors on our business. The industry has also experienced significant economic downturns, characterized by diminished product demand and production over-capacity. We have sought to reduce our exposure to this industry cyclically by selling proprietary products that cannot be easily or quickly replaced to

a geographically diverse base of customers across a broad range of market segments. However, we have experienced substantial period-to-period fluctuations in operating results and expect, in the future, to experience period-to-period fluctuations in operating results due to general industry or economic conditions. In particular, our business and operating results have been adversely impacted by global economic conditions.

We are exposed to various risks related to legal proceedings or claims.

We are currently, and in the future may be, involved in legal proceedings or claims regarding patent infringement, intellectual property rights, contracts and other matters. As is typical in the semiconductor industry, we receive notifications from customers from time to time who believe that we owe them indemnification or other obligations related to infringement claims made against the customers by third parties. These legal proceedings and claims, whether with or without merit, could result in substantial cost to us and divert our resources. If we are not able to resolve a claim, negotiate a settlement of a matter, obtain necessary licenses on commercially reasonable terms, reengineer our products or processes to avoid infringement, and/or successfully prosecute or defend our position, we could incur uninsured liability in any of them, be required to take an appropriate charge to operations, be enjoined from selling a material portion of our products or using certain processes, suffer a reduction or elimination in the value of our inventories, and our business, financial condition or results of operations could be harmed.

It is also possible that from time to time we may be subject to claims related to the performance or use of our products. These claims may be due to products' nonconformance to our specifications, or specifications agreed upon with the customer, changes in our manufacturing processes, and unexpected end customer system issues due to the interaction with our products or insufficient design or testing by our customers. We could incur significant expenses related to such matters, including, but not limited to,

costs related to writing off the value of inventory of nonconforming products;

recalling nonconforming products;

providing support services, product replacements, or modification to products and the defense of such claims;

diversion of resources from other projects;

lost revenue or a delay in the recognition of revenue due to cancellation of orders and unpaid receivables;

customer imposed fines or penalties for failure to meet contractual requirements; and

a requirement to pay damages.

Because the systems into which our products are integrated have a higher cost of goods than the products we sell, these expenses and damages may be significantly higher than the sales and profits we received from the products involved. While we specifically exclude consequential damages in our standard terms and conditions, our ability to avoid such liabilities may be limited by applicable law. We do have liability insurance which covers damages arising out of product defects, but we do not expect that insurance will cover all claims or be of a sufficient amount to fully protect against such claims. Costs or payments we may make in connection with these customer claims may adversely affect the results of our operations.

Further, we sell to customers in industries such as automotive, aerospace, and medical, where failure of the systems in which our products are integrated could cause damage to property or persons. We may be subject to claims if our products, or interactions with our products, cause the system failures. We will face increased exposure to claims if there are substantial increases in either the volume of our sales into these applications or the frequency of system failures integrating our products.

Failure to adequately protect our intellectual property could result in lost revenue or market opportunities.

Our ability to obtain patents, licenses and other intellectual property rights covering our products and manufacturing processes is important for our success. To that end, we have acquired certain patents and patent licenses and intend to continue to seek patents on our inventions and manufacturing processes. The process of seeking patent protection can be long and expensive, and patents may not be issued from currently pending or future applications. In addition, our existing patents and any new patents that are issued may not be of sufficient scope or strength to provide meaningful protection or any commercial advantage to us. We may be subject to or

may ourselves initiate interference proceedings in the U.S. Patent and Trademark Office, which can require significant financial and management resources. In addition, the laws of certain foreign countries do not protect our intellectual property rights to the same extent as the laws of the U.S. Infringement of our intellectual property rights by a third party could result in uncompensated lost market and revenue opportunities for us.

Our operating results may be adversely impacted if economic conditions impact the financial viability of our customers, distributors, or suppliers.

We regularly review the financial performance of our customers, distributors and suppliers. However, global economic conditions may adversely impact the financial viability of our customers, distributors or suppliers. The financial failure of a large customer or distributor, an important supplier, or a group thereof, could have an adverse impact on our operating results and could result in us not being able to collect our accounts receivable balances.

We do not typically have long-term contracts with our customers.

We do not typically enter into long-term contracts with our customers and we cannot be certain about future order levels from our customers. When we do enter into customer contracts, the contract is generally cancelable at the convenience of the customer. Even though we have over 60,000 customers and our ten largest direct customers made up approximately 9% of our total revenue for the six months ended September 30, 2009, cancellation of customer contracts could have an adverse financial impact on our revenue and profits.

Further, as the practice has become more commonplace in the industry, we have entered into contracts with certain customers that differ from our standard terms of sale. Under these contracts we commit to supply quantities of products on scheduled delivery dates. If we become unable to supply the customer as required under the contract, the customer may incur additional production costs, lost revenues due to subsequent delays in their own manufacturing schedule, or quality related issues. Under these contracts, we may be liable for the costs the customer has incurred. While we try to limit such liabilities, if they should arise, there may be a material adverse impact on our results of operation and financial condition.

Business interruptions could harm our business.

Operations at any of our facilities, or at any of our wafer fabrication or assembly and test subcontractors, may be disrupted for reasons beyond our control, including work stoppages, power loss, incidents of terrorism or security risk, political instability, public health issues, telecommunications, transportation or other infrastructure failure, fire, earthquake, floods, or other natural disasters. If operations at any of our facilities, or our subcontractors' facilities are interrupted, we may not be able to shift production to other facilities on a timely basis. If this occurs, we would likely experience delays in shipments of products to our customers and alternate sources for production may be unavailable on acceptable terms. This could result in reduced revenues and profits and the cancellation of orders or loss of customers. In addition, business interruption insurance will likely not be enough to compensate us for any losses that may occur and any losses or damages incurred by us as a result of business interruptions could significantly harm our business.

We are highly dependent on foreign sales and operations, which exposes us to foreign political and economic risks.

Sales to foreign customers account for a substantial portion of our net sales. During fiscal 2009, approximately 75% of our net sales were made to foreign customers. During the first six months of fiscal 2010, approximately 77% of our net sales were made to foreign customers. We purchase a substantial portion of our raw materials and equipment from foreign suppliers. In addition, we own product assembly and testing facilities located near Bangkok, Thailand, which has experienced periods of political uncertainty in the past. We also use various foreign contractors for a portion of our assembly and testing and for a portion of our wafer fabrication requirements. Substantially all of our finished goods inventory is maintained in Thailand.

Our reliance on foreign operations, foreign suppliers, maintenance of substantially all of our finished goods inventory at foreign locations and significant foreign sales exposes us to foreign political and economic risks, including, but not limited to:

political, social and economic instability;

public health conditions;

trade restrictions and changes in tariffs;

import and export license requirements and restrictions;

difficulties in staffing and managing international operations;

employment regulations;

disruptions in international transport or delivery;

difficulties in collecting receivables;

economic slowdown in the worldwide markets served by us; and

potentially adverse tax consequences.

If any of these risks materialize, our sales could decrease and/or our operating results could suffer.

Fluctuations in foreign currency could impact our operating results. We use forward currency exchange contracts to reduce the adverse earnings impact from the effect of exchange rate fluctuations on our non-U.S. dollar net balance sheet exposures. Nevertheless, in periods when the U.S. dollar significantly fluctuates in relation to the non-U.S. currencies in which we transact business, the value of our non-U.S. dollar transactions can have an adverse effect on our results of operations and financial condition.

Interruptions in our information technology systems could adversely affect our business.

We rely on the efficient and uninterrupted operation of complex information technology systems and networks to operate our business. Any significant system or network disruption, including but not limited to new system implementations, computer viruses, security breaches, or energy blackouts could have a material adverse impact on our operations, sales and operating results. We have implemented measures to manage our risks related to such disruptions, but such disruptions could still occur and negatively impact our operations and financial results. In addition, we may incur additional costs to remedy the damages caused by these disruptions or security breaches.

The occurrence of events for which we are self-insured, or which exceed our insurance limits, may adversely affect our profitability and liquidity.

We have insurance contracts with independent insurance companies related to many different types of risk; however, we self-insure for some potentially significant risks and obligations. In these circumstances, we have determined that it is more cost effective to self-insure certain risks than to pay the high premium costs. The risks and exposures that we self-insure include, but are not limited to, certain property, product defects, political risks, and patent infringement. Should there be a loss or adverse judgment or other decision in an area for which we are self-insured, then our financial condition, result of operations and liquidity may be adversely affected.

We are subject to stringent environmental regulations, which may force us to incur significant expenses.

We must comply with many different federal, state, local and foreign governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our products and manufacturing processes. Our failure to comply with present or future regulations could result in the imposition of fines, suspension of production or a cessation of operations. Such environmental regulations have required us in the past and could require us in the future to acquire costly equipment or to incur other significant expenses to comply with such regulations. Any failure by us to control the use of or adequately restrict the discharge of hazardous substances could subject us to future liabilities. Environmental problems may occur that could subject us to future costs or liabilities.

Over the past few years, there has been an expansion in environmental laws focusing on reducing or eliminating hazardous substances in electronic products. For example, the EU RoHS Directive provided that beginning on July 1, 2006, electronic products sold into Europe were required to meet stringent chemical restrictions, including the absence of lead. Other countries, such as the U.S., China and Korea, have enacted or may enact laws or regulations similar to those of the EU. These and other future environmental regulations could require us to reengineer certain of our existing products and may make it more expensive for us to manufacture

and sell our products. Over the last several years, the number and complexity of laws focused on the energy efficiency of electronic products and accessories; the recycling of electronic products; and the reduction in quantity and the recycling of packaging materials have expanded significantly. It may be difficult for us to timely comply with these laws and we may not have sufficient quantities of compliant products to meet customers' needs, thereby adversely impacting our sales and profitability. We may also have to write off inventory in the event that we hold inventory that is not saleable as a result of changes to regulations. We expect these risks and trends to continue. In addition, we anticipate increased customer requirements to meet voluntary criteria related to the reduction or elimination of hazardous substances in our products and energy efficiency measures.

Regulatory authorities in jurisdictions into which we ship our products could levy fines or restrict our ability to export products.

A significant portion of our sales are made outside of the U.S. through the exporting and re-exporting of products. In addition to local jurisdictions' export regulations, our U.S.-manufactured products or products based on U.S. technology are subject to Export Administration Regulations (EAR) when exported and re-exported to and from international jurisdictions. Licenses or proper license exceptions may be required for the shipment of our products to certain countries. Non-compliance with EAR or other export regulations can result in penalties including denial of export privileges, fines, criminal penalties, and seizure of products. Such penalties could have a material adverse effect on our business including our ability to meet our net sales and earnings targets.

The outcome of currently ongoing and future examinations of our income tax returns by the IRS could have an adverse effect on our results of operations.

We are subject to continued examination of our income tax returns by the IRS and other tax authorities for fiscal 2002 and later, other than fiscal 2005. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuing examinations will not have an adverse effect on our future operating results.

The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors.

The market price of our common stock has fluctuated significantly in the past and is likely to fluctuate in the future. The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors, many of which are beyond our control, including, but not limited to:

·	quarterly variations in our operating results and the operating results of other technology companies;

·	actual or anticipated announcements of technical innovations or new products by us or our competitors;

·	changes in analysts' estimates of our financial performance or buy/sell recommendations;

·	changes in our financial guidance or our failure to meet such guidance;

·	general conditions in the semiconductor industry; and

·	global economic and financial conditions.

In addition, the stock market has recently experienced significant price and volume fluctuations that have affected the market prices for many companies and that often have been unrelated to the operating performance of such companies. These broad market fluctuations and other factors have harmed and may harm the market price of our common stock.

In the event we make acquisitions, we may not be able to successfully integrate such acquisitions or attain the anticipated benefits.

We may consider strategic acquisitions if such opportunities arise. Any transactions that we consider may involve a number of risks including the diversion of our management's attention from our existing business or possible adverse effects on our operating results during the integration process for those transactions that we complete. In addition, we may not be able to successfully or profitably integrate, operate, maintain and manage any newly acquired operations or employees. We may not be able to maintain uniform standards, controls, procedures and policies, which may lead to operational inefficiencies.

Our financial condition and results of operations could be adversely affected if we do not effectively manage our liabilities.

As a result of our sale of $1.15 billion of 2.125% junior subordinated convertible debentures in December 2007, we have a substantially greater amount of long-term debt than we have maintained in the past. Our maintenance of substantial levels of debt could adversely affect our ability to take advantage of corporate opportunities and could adversely affect our financial condition and results of operations. We may need or desire to refinance all or a portion of our debentures or any other future indebtedness that we incur on or before the maturity of the debentures. There can be no assurance that we will be able to refinance any of our indebtedness on commercially reasonable terms, if at all.

Conversion of our debentures will dilute the ownership interest of existing stockholders, including holders who had previously converted their debentures.

The conversion of some or all of our outstanding debentures will dilute the ownership interest of existing stockholders to the extent we deliver common stock upon conversion of the debentures. Upon conversion, we may satisfy our conversion obligation by delivering cash, shares of common stock or any combination, at our option. If upon conversion we elect to deliver cash for the lesser of the conversion value and principal amount of the debentures, we would pay the holder the cash value of the applicable number of shares of our common stock. Upon conversion, we intend to satisfy the lesser of the principal amount or the conversion value of the debentures in cash. If the conversion value of a debenture exceeds the principal amount of the debenture, we may also elect to deliver cash in lieu of common stock for the conversion value in excess of one thousand dollars principal amount (conversion spread). There would be no adjustment to the numerator in the net income per common share computation for the cash settled portion of the debentures as that portion of the debt instrument will always be settled in cash. The conversion spread will be included in the denominator for the computation of diluted net income per common share. Any sales in the public market of any common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the debentures may encourage short selling by market participants because the conversion of the debentures could be used to satisfy short positions, or anticipated conversion of the debentures into shares of our common stock could depress the price of our common stock.

Our Reported Financial Results May be Adversely Affected by New Accounting Pronouncements or Changes in Existing Accounting Standards and Practices.

We prepare our financial statements in conformity with accounting principles generally accepted in the U.S. These accounting principles are subject to interpretation by the FASB, the SEC and various organizations formed to interpret and create appropriate accounting standards and practices. New accounting pronouncements and varying interpretations of accounting standards and practices have occurred and may occur in the future. New accounting pronouncements or a change in the interpretation of existing accounting standards or practices may have a significant effect on our reported financial results and may even affect our reporting of transactions completed before the change is announced or effective.

Recently proposed U.S. tax legislation regarding our foreign earnings could materially and adversely impact our business and financial results.

Currently, a majority of our revenue is generated from customers located outside the U.S., and a substantial portion of our assets, including employees, are located outside the U.S. Present U.S. income taxes and foreign withholding taxes have not been provided on undistributed earnings for certain of our non-U.S. subsidiaries, because such earnings are intended to be indefinitely reinvested in the operations of those subsidiaries. President Obama's administration has announced initiatives that would substantially reduce our ability to defer U.S. taxes including repealing the deferral of U.S. taxation of foreign earnings, eliminating utilization of or substantially reducing our ability to claim foreign tax credits, and eliminating various tax deductions until foreign earnings are repatriated to the U.S. If any of these proposals become law, they could have a material negative impact on our financial position and results of operations.
