QLOGIC CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
Note 1. Basis of Presentation
     In the opinion of management of QLogic Corporation (QLogic or the Company), the accompanying unaudited condensed consolidated financial statements contain all normal recurring accruals and adjustments necessary to present fairly the Company’s consolidated financial position, results of operations and cash flows. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 29, 2009. The results of operations for the three and nine months ended December 27, 2009 are not necessarily indicative of the results that may be expected for the entire fiscal year. The Company has evaluated subsequent events through February 2, 2010, the date the financial statements were issued. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Among the significant estimates affecting the consolidated financial statements are those related to revenue recognition, stock-based compensation, income taxes, investment securities, inventories, goodwill and long-lived assets.
     The Company evaluates its estimates on an ongoing basis using historical experience and other factors, including the current economic environment. The current volatility in the capital markets and the economy has increased the uncertainty in the Company’s estimates, including estimates impacting investment securities and long-lived assets. Significant judgment is required in determining the fair value of investment securities in inactive markets, as well as determining when declines in fair value constitute an other-than-temporary impairment. In addition, significant judgment is required in determining whether a potential indicator of impairment of the Company’s long-lived assets exists and in estimating future cash flows for any necessary impairment tests. Significant judgment is also required in determining the fair value of assets acquired and liabilities assumed in a business combination, including the fair value of identifiable intangible assets. As future events unfold and their effects cannot be determined with precision, actual results could differ significantly from management’s estimates.
Note 2. Business Combination
     On April 27, 2009, the Company acquired NetXen, Inc. (NetXen) in a merger transaction. Cash consideration was $17.6 million for all outstanding NetXen capital stock. NetXen developed, marketed and sold Ethernet adapter and controller products targeted at the enterprise server market. The acquisition expanded the Company’s product portfolio to include Ethernet networking products that are complementary to existing products. The acquisition also expanded the Company’s expertise to better address a wider range of emerging customer requirements for converged networks. The acquisition agreement provided for an adjustment to the purchase price based on the final working capital as of the date of acquisition. The Company finalized the working capital adjustment in the second quarter of fiscal 2010 and paid an additional $0.4 million. The acquisition agreement also required that $5.1 million of the consideration be placed into an escrow account in connection with certain representations and warranties. The consideration placed in escrow is scheduled to be released between 18 and 24 months after the date of the acquisition. The escrowed amounts have been accounted for as cash consideration as of the date of the acquisition.
     The consideration paid in excess of the fair value of the net assets acquired totaled $0.9 million, which has been recorded as goodwill in the accompanying condensed consolidated balance sheet as of December 27, 2009. None of the goodwill resulting from the acquisition will be tax deductible.

     The amortized cost and estimated fair value of debt securities as of December 27, 2009, by contractual maturity, are presented below. Expected maturities will differ from contractual maturities because the issuers of securities may have the right to repay obligations without prepayment penalties. Certain debt instruments, although possessing a contractual maturity greater than one year, are classified as short-term investment securities based on their ability to be traded on active markets and availability for current operations.

     As of December 27, 2009 and December 28, 2008, the fair value of certain of the Company’s available-for-sale securities was less than their cost basis. Management reviewed various factors in determining whether to recognize an impairment charge related to these unrealized losses, including the current financial and credit market environment, the financial condition and near-term prospects of the issuer of the investment security, the magnitude of the unrealized loss compared to the cost of the investment, the length of time the investment had been in a loss position and the Company’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery of market value. As of December 27, 2009, the Company determined that the unrealized losses are temporary in nature and recorded them as a component of accumulated other comprehensive income. Based on this analysis, the Company determined that a portion of the unrealized losses associated with the Company’s portfolio of available-for-sale securities were other-than-temporary and recorded impairment charges of $4.3 million and $10.3 million, which are included in interest and other income, net, in the accompanying condensed consolidated statements of income for the three and nine months ended December 28, 2008, respectively.

     The accompanying condensed consolidated statement of cash flows for the nine months ended December 28, 2008 has been adjusted to reflect net gains from the sale of available-for-sale securities as an investing activity. This adjustment resulted in a $0.9 million decrease in cash flow from operating activities and a corresponding increase in cash flow from investing activities. The Company has evaluated the materiality of this adjustment from a qualitative and quantitative perspective and concluded it is not material.
     Trading Securities
     The Company’s portfolio of trading securities consists of the following:
                 
    December 27,     March 29,  
    2009     2009  
    (In thousands)  
Auction rate debt securities
  $ 17,081     $ 20,741

    2,981       9,281  
 
           
Total trading securities
  $ 24,396     $ 34,891  
 
           
     The Company’s trading securities include investments in auction rate securities (ARS), the majority of which are rated AA or higher. During late fiscal 2008, the market auctions of many ARS began to fail, including auctions for the Company’s ARS. The underlying assets for the auction rate debt securities in the Company’s portfolio are student loans, substantially all of which are backed by the federal government under the Federal Family Education Loan Program. The underlying assets of the Company’s auction rate preferred securities are the respective funds’ investment portfolios.
     In November 2008, the Company entered into an agreement with the broker for all of the ARS currently held by the Company, which provides the Company with certain rights (ARS Rights), in exchange for the release of potential claims and damages against the broker. The ARS Rights entitle the Company to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, which price is referred to as “par.” The ARS Rights may be exercised by the Company at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold. Under the ARS Rights, the broker may, at its discretion, purchase the ARS at any time through July 2, 2012 without prior notice to the Company and must pay the Company par value for the ARS within one day of the sale transaction settlement.
     The ARS Rights agreement, a legally enforceable contract, resulted in put options that were recognized as free standing assets separate from the ARS. The Company elected to measure the put options at fair value. In connection with the election to measure the put options at fair value, the Company classified these financial instruments as trading securities and recorded the initial fair value of $8.1 million in investment securities. The associated gains are recognized in interest and other income, net, in the accompanying

condensed consolidated statements of income for the three and nine months ended December 28, 2008. The ARS associated with the ARS Rights, previously classified as available-for-sale securities, were reclassified to trading securities during the three months ended December 28, 2008. As a result, the Company recognized a loss of $3.4 million, which had previously been recorded in accumulated other comprehensive income and $1.1 million related to changes in the fair market value of the trading securities subsequent to the reclassification. The loss related to the ARS is included in interest and other income, net, in the accompanying condensed consolidated statements of income for the three and nine months ended December 28, 2008.
     As the ARS Rights may be exercised beginning June 30, 2010, the Company has classified its auction rate debt and preferred securities, as well as the related put options, as short-term investment securities as of December 27, 2009.
     Other Investment Securities
     The Company’s other investment securities are comprised of a money market fund and an enhanced cash fund sponsored by The Reserve (an asset management company), which suspended trading and redemptions in September 2008. These funds are in the process of being liquidated and the Company expects the liquidation to occur in stages with proceeds distributed as the underlying securities mature or are sold. These funds do not have readily determinable fair values and thus have been accounted for under the cost method.
     During fiscal 2009, the Company reclassified $57.2 million of investments in the funds sponsored by The Reserve from cash equivalents to short-term investments. This reclassification has been presented separately as an investing activity in the accompanying condensed consolidated statement of cash flows for the nine months ended December 28, 2008, to conform to the presentation in the fiscal 2009 annual consolidated financial statements. The Company received net proceeds from the partial liquidation of these funds totaling $3.1 million and $6.5 million for the nine months ended December 27, 2009 and December 28, 2008, respectively, which are presented separately as an investing activity in the accompanying condensed consolidated statements of cash flows. Also during the nine months ended December 28, 2008, the Company recorded a $1.7 million impairment charge related to these investments.
     Fair Value Measurements
     Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. A description of the three levels of inputs is as follows:
    Level 1 — Quoted prices in active markets for identical assets or liabilities.
 
    Level 2 — Inputs other than Level 1 inputs that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
 
    Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

     The Company’s investments in auction rate securities and the related put options are classified within Level 3 because there are currently no active markets for these securities and the Company is unable to obtain independent valuations from market sources. Therefore, the auction rate securities and the related put options were primarily valued based on an income approach using estimates of future cash flows. The assumptions used in preparing these discounted cash flow models included estimates for the amount and timing of future interest and principal payments, the collateralization of underlying security investments, the creditworthiness of the issuer and the rate of return required by investors to own these securities in the current environment, including call and liquidity premiums. The total amount of assets measured using Level 3 valuation methodologies represented 3% of total assets as of December 27, 2009.
     A summary of the changes in Level 3 assets measured at fair value on a recurring basis for the three and nine months ended December 27, 2009 is as follows:

Note 10. Income Taxes
     The Company’s provision for income taxes was $19.0 million and $55.5 million for the nine months ended December 27, 2009 and December 28, 2008, respectively. The effective income tax rate was 24% and 38% for the nine months ended December 27, 2009 and December 28, 2008, respectively. The effective income tax rate is based upon the estimated income for the year, the composition of the estimated income in different tax jurisdictions, and adjustments, if any, in the applicable quarterly periods for the potential tax consequences, benefits or resolutions of tax audits or other tax contingencies. The allocation of taxable income to domestic and foreign tax jurisdictions impacts the effective tax rate as the Company’s income tax rate in foreign jurisdictions is lower than its income tax rate in the U.S.

These stock-based awards have been excluded from the diluted net income per share calculations because their effect would have been antidilutive.

Overview
     We are a designer and supplier of high performance storage networking, server networking, data networking and converged networking infrastructure solutions. Our solutions are sold worldwide, primarily to original equipment manufacturers, or OEMs, and distributors. We sell Fibre Channel and Internet Small Computer Systems Interface, or iSCSI, host bus adapters; InfiniBand® host channel adapters; Fibre Channel over Ethernet, or FCoE, converged network adapters; and Ethernet adapters, which we collectively refer to as Host Products. We sell Fibre Channel switches, including stackable edge, blade and virtualized pass-through switches; InfiniBand switches, including high-end multi-protocol directors, edge and blade switches; Enhanced Ethernet pass-through modules; and storage routers for bridging Fibre Channel and iSCSI networks, which we collectively refer to as Network Products. We also sell Fibre Channel controllers, iSCSI controllers, converged network controllers and Ethernet controllers, all for select embedded and target applications, which we collectively refer to as Silicon Products.
     Our products are incorporated in solutions from a number of OEM customers, including Cisco Systems, Inc., Dell Inc., EMC Corporation, Hewlett-Packard Company, International Business Machines Corporation, NetApp, Inc., Sun Microsystems, Inc. and many others.
     Business Combination
     On April 27, 2009, we acquired NetXen, Inc. (NetXen) in a merger transaction. Cash consideration was $17.6 million for all outstanding NetXen capital stock. NetXen developed, marketed and sold Ethernet adapter and controller products targeted at the enterprise server market. The acquisition expanded our product portfolio to include Ethernet networking products that are complementary to our existing products. The acquisition also expanded our expertise to better address a wider range of emerging customer requirements for converged networks. The acquisition agreement required that $5.1 million of the consideration be placed into an escrow account in connection with certain representations and warranties. The consideration placed in escrow is scheduled to be released between 18 and 24 months after the date of the acquisition. The escrowed amounts have been accounted for as cash consideration as of the date of the acquisition.
     Third Quarter Financial Highlights and Other Information
     A summary of the key factors and significant events which impacted our financial performance during the third quarter of fiscal 2010 are as follows:
    Net revenues of $149.1 million for the third quarter of fiscal 2010 increased sequentially by $17.6 million, or 13%, from $131.5 million in the second quarter of fiscal 2010. Revenues from Host Products of $110.4 million for the third quarter of fiscal 2010 increased sequentially by $16.4 million, or 17%, from $94.0 million in the second quarter of fiscal 2010.
 
    Gross profit as a percentage of net revenues increased to 64.4% for the third quarter of fiscal 2010 from 63.7% in the second quarter of fiscal 2010.

Table of Contents

    Operating income as a percentage of net revenues increased to 23.2% for the third quarter of fiscal 2010 from 15.8% in the second quarter of fiscal 2010.
 
    Net income increased to $28.6 million, or $0.25 per diluted share, in the third quarter of fiscal 2010 from $16.2 million, or $0.14 per diluted share, in the second quarter of fiscal 2010.
 
    Cash, cash equivalents and investment securities increased to $349.2 million at December 27, 2009 from $340.4 million at September 27, 2009.
 
    Accounts receivable was $86.1 million as of December 27, 2009, compared to $75.2 million as of September 27, 2009. Days sales outstanding (DSO) in receivables was 53 days as of December 27, 2009 compared to 52 days as of September 27, 2009.
 
    Inventories were $21.8 million as of December 27, 2009, compared to $23.3 million as of September 27, 2009. Our annualized inventory turns in the third quarter of fiscal 2010 increased to 9.7 turns from 8.2 turns in the second quarter of fiscal 2010.
     As a result of worldwide economic uncertainty, it is extremely difficult for us and our customers to forecast future sales levels based on historical information and trends. Portions of our expenses are fixed and others are tied to expected levels of sales activities. To the extent that we do not achieve our anticipated level of sales, our gross profit and net income could be adversely affected until such expenses are reduced to an appropriate level.

     Historically, the global marketplace for network infrastructure solutions has expanded in response to the information storage requirements of enterprise business environments, as well as the market for solutions in high performance computing environments. These markets have been characterized by rapid advances in technology and related product performance, which has generally resulted in declining average selling prices over time. In general, our revenues have been favorably affected by increases in units sold as a result of market expansion and the release of new products. The favorable effect on our revenues as a result of increases in volume has been partially offset by the impact of declining average selling prices.
     The United States and other countries around the world have been experiencing deteriorating economic conditions. This economic decline has resulted in a global downturn in information technology spending rates, which has negatively impacted our revenue and operating results. Accordingly, it is extremely difficult for us to forecast future sales levels and historical information may not be indicative of future trends.
     Our net revenues are derived primarily from the sale of Host Products, Network Products and Silicon Products. Net revenues decreased 9% to $149.1 million for the three months ended December 27, 2009 from $163.7 million for the three months ended

Table of Contents

December 28, 2008. This decrease was primarily the result of a $1.8 million, or 2%, decrease in revenue from Host Products; a $5.4 million, or 16%, decrease in revenue from Network Products; and a $7.8 million, or 47%, decrease in revenue from Silicon Products. The decrease in revenue from Host Products was primarily due to a 6% decrease in the average selling prices of host bus adapters on a consistent unit volume, partially offset by an over 400% increase in revenue from the early market acceptance of FCoE adapters and the addition of Ethernet adapters as a result of the NetXen acquisition. The decrease in revenue from Network Products was primarily due to a 61% decrease in the number of Infiniband switches sold, partially offset by a 48% increase in the average selling prices of these products, primarily due to a change in mix to higher capacity switches. Revenue from Network Products was also impacted by a 10% decrease in the number of Fibre Channel switches sold and a 2% decrease in the average selling prices of these products. The decrease in revenue from Silicon Products was due primarily to a 42% decrease in the units of protocol chips sold and a 10% decrease in the average selling prices of these products. Net revenues for the three months ended December 27, 2009 included $2.6 million of royalty and service revenue compared with $2.2 million of royalty and service revenue for the three months ended December 28, 2008. Royalty and service revenues are unpredictable and we do not expect them to be significant to our overall revenues.
     Net revenues decreased 20% to $403.4 million for the nine months ended December 27, 2009 from $503.3 million for the nine months ended December 28, 2008. This decrease was primarily the result of a $59.7 million, or 17%, decrease in revenue from Host Products; a $15.6 million, or 17%, decrease in revenue from Network Products; and a $22.0 million, or 46%, decrease in revenue from Silicon Products. The decrease in revenue from Host Products was primarily due to a 14% decrease in the quantity of host bus adapters sold and a 6% decrease in the average selling prices of these products, partially offset by an over 500% increase in revenue from the early market acceptance of FCoE adapters and the addition of Ethernet adapters as a result of the NetXen acquisition. The decrease in revenue from Network Products was primarily due to a 15% decrease in the number of Fibre Channel switches sold and a 10% decrease in the average selling prices of these products. The decrease in revenue from Silicon Products was due primarily to a 34% decrease in the units of protocol chips sold, an 11% decrease in the average selling prices of these products and a $3.8 million decrease in revenue from management controller chips, as these products reached end-of-life in fiscal 2009. Net revenues for the nine months ended December 27, 2009 included $8.0 million of royalty and service revenue compared with $10.6 million of royalty and service revenue for the nine months ended December 28, 2008.
     A small number of our customers account for a substantial portion of our net revenues, and we expect that a small number of customers will continue to represent a substantial portion of our net revenues for the foreseeable future. Our top ten customers accounted for 88% and 83% of net revenues during the nine months ended December 27, 2009 and December, 28, 2008, respectively.
     We believe that our major customers continually evaluate whether or not to purchase products from alternative or additional sources. Accordingly, there can be no assurance that a major customer will not reduce, delay or eliminate its purchases from us. Any such reduction, delay or loss of purchases could have a material adverse effect on our business, financial condition or results of operations.

  Gross Profit
     Gross profit represents net revenues less cost of revenues. Cost of revenues consists primarily of the cost of purchased products, assembly and test services; costs associated with product procurement, inventory management, logistics and product quality; and the amortization of purchased intangible assets. A summary of our gross profit and related percentage of net revenues is as follows:
                                 
    Three Months Ended   Nine Months Ended
    December 27,   December 28,   December 27,   December 28,
    2009   2008   2009   2008
    (Dollars in millions)
Gross profit
  $ 96.1     $ 108.9     $ 258.1     $ 337.8  
Percentage of net revenues
    64.4 %     66.5 %     64.0 %     67.1 %
     Gross profit for the three months ended December 27, 2009 decreased $12.8 million, or 12%, from gross profit for the three months ended December 28, 2008. The gross profit percentage for the three months ended December 27, 2009 was 64.4% and decreased from 66.5% for the corresponding period in the prior year. The decrease in gross profit percentage was primarily due to lower volumes to absorb manufacturing costs and a change in product mix.
     Gross profit for the nine months ended December 27, 2009 decreased $79.7 million, or 24%, from gross profit for the nine months ended December 28, 2008. The gross profit percentage for the nine months ended December 27, 2009 was 64.0% and decreased from 67.1% for the corresponding period in the prior year. The decrease in gross profit percentage was primarily due to lower volumes to absorb manufacturing costs, a change in product mix and a $3.5 million one-time royalty in fiscal 2009, partially offset by a $5.0 million decrease in amortization of purchased intangible assets.
     Our ability to maintain our current gross profit percentage can be significantly affected by factors such as manufacturing volumes over which fixed costs are absorbed, sales discounts and customer incentives, component costs, the mix of products shipped, the transition to new products, competitive price pressures, the timeliness of volume shipments of new products, the level of royalties received, our ability to achieve manufacturing cost reductions, and amortization and impairments of purchased intangible assets. We anticipate that it will be increasingly difficult to reduce manufacturing costs. As a result of these and other factors, it may be difficult to maintain our gross profit percentage consistent with historical periods and it may decline in the future.
  Operating Expenses
     Our operating expenses are summarized in the following table:
                                 
    Three Months Ended     Nine Months Ended  
    December 27,     December 28,     December 27,     December 28,

    41.3 %     38.9 %     46.2 %     38.7 %
 
                       
     Engineering and Development. Engineering and development expenses consist primarily of compensation and related employee benefit costs, service and material costs, occupancy costs and related computer support costs. During the three months ended December 27, 2009, engineering and development expenses increased to $34.0 million from $33.1 million for the three months ended December 28, 2008. The increase in engineering and development expenses was primarily due to a $0.5 million increase in stock-based compensation and a $0.4 million increase in new product development.

Table of Contents

     During the nine months ended December 27, 2009, engineering and development expenses increased to $102.3 million from $100.6 million for the nine months ended December 28, 2008. The increase in engineering and development expenses was primarily due to a $1.8 million increase in stock-based compensation.
     We believe continued investments in engineering and development activities are critical to achieving future design wins, expansion of our customer base and revenue growth opportunities.
     Sales and Marketing. Sales and marketing expenses consist primarily of compensation and related employee benefit costs, sales commissions, promotional activities and travel for sales and marketing personnel. Sales and marketing expenses decreased to $18.8 million for the three months ended December 27, 2009 from $20.9 million for the three months ended December 28, 2008. The decrease in sales and marketing expenses was due primarily to a $1.3 million decrease in promotional costs, including the costs for certain sales and marketing programs, and a $0.5 million decrease in amortization of purchased intangible assets. The decrease in amortization expense is due to an intangible asset becoming fully amortized during the three months ended December 27, 2009.
     Sales and marketing expenses decreased to $58.2 million for the nine months ended December 27, 2009 from $67.9 million for the nine months ended December 28, 2008. The decrease in sales and marketing expenses was due primarily to a $4.5 million decrease in promotional costs, including the costs for certain sales and marketing programs, and a $1.3 million decrease in travel costs, both related to our cost-cutting measures implemented in the second half of fiscal 2009. In addition, cash compensation and related employee benefit costs decreased by $2.0 million primarily due to decreased commissions as a result of lower revenues. Also, amortization of purchased intangible assets decreased by $0.5 million, as discussed above.
     We believe continued investments in our sales and marketing organizational infrastructure and related marketing programs are critical to the success of our strategy of expanding our customer base and enhancing relationships with our existing customers.
     General and Administrative. General and administrative expenses consist primarily of compensation and related employee benefit costs for executive, finance, accounting, human resources, legal and information technology personnel. Non-compensation components of general and administrative expenses include accounting, legal and other professional fees, facilities expenses and other corporate expenses. General and administrative expenses increased to $8.8 million for the three months ended December 27, 2009 from $8.2 million for the three months ended December 28, 2008. The increase in general and administrative expenses was due primarily to a $0.6 million increase in stock-based compensation.
     General and administrative expenses were consistent at $24.9 million for the nine months ended December 27, 2009 and December 28, 2008, respectively. During the nine months ended December 27, 2009, stock-based compensation increased by $1.4 million, which was partially offset by a $1.2 million decrease in cash compensation and related employee benefit costs compared to the nine months ended December 28, 2008.
     Special Charges. We recorded special charges of $0.9 million during the three months ended September 27, 2009, related to our acquisition of NetXen. The special charges consisted of exit costs related to the former NetXen leased facility that we vacated and severance benefits for involuntarily terminated employees. As of December 27, 2009, all severance benefits had been paid. The unpaid exit costs associated with the leased facility are expected to be paid over the next nine months.
     During the three months ended December 28, 2008, we implemented a workforce reduction initiative, primarily in response to the macroeconomic environment, and recorded special charges totaling $1.4 million associated with the cost of severance benefits for the affected employees, all of which had been paid as of December 27, 2009.

  Interest and Other Income, Net
     Components of our interest and other income, net, are as follows:

  $ 1.7     $ 2.5     $ 7.0     $ 2.0  
 
                       
     Interest income is earned on our portfolio of investment securities and cash equivalents. The decrease in interest income for the three and nine months ended December 27, 2009, from the corresponding periods in the prior year, was primarily due to a decline in interest rates, as well as, a decrease in the average balance of our investment securities and cash equivalents.
     The gain on recognition of put options, during the three and nine months ended December 28, 2008, resulted from an agreement that we entered into with the broker for substantially all of our auction rate securities (ARS) that entitles us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold.
     The loss on trading securities, during the three and nine months ended December 28, 2008, was due to the realization of $3.4 million of previously unrealized losses that were transferred from accumulated other comprehensive income as a result of the reclassification of the ARS from available-for-sale to trading securities and $1.1 million related to changes in the fair market value of the trading securities subsequent to the reclassification.
     We reviewed various factors in determining whether to recognize an impairment charge related to our unrealized losses in available-for-sale securities, including the current financial and credit market environment, the financial condition and near-term prospects of the issuer of the security, the magnitude of the loss compared to the cost of the investment, the length of time the investment has been in a loss position and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery of market value. Based on this analysis, we determined that a portion of the unrealized losses were other-than-temporary and recorded impairment charges of $4.3 million and $10.3 million related to our portfolio of available-for-sale securities during the three and nine months ended December 28, 2008, respectively. In addition, during the nine months ended December 28, 2008, we recorded a $1.7 million impairment charge related to our cost basis investments in a money market fund and an enhanced cash fund sponsored by The Reserve (an asset management company).
  Income Taxes
     Our effective income tax rate was 24% and 38% for the nine months ended December 27, 2009 and December 28, 2008, respectively. We expect the annual effective income tax rate for fiscal 2010 to approximate 25% as compared to our actual annual effective tax rate of 36% for fiscal 2009. Our estimated effective tax rate for fiscal 2010 is favorably impacted by additional payments made in fiscal 2009 in connection with an intercompany technology license related to our intellectual property. These additional license payments resulted in a larger portion of income taxed at U.S. rates in fiscal 2009 compared to our estimates for fiscal 2010. In addition, the effective income tax rate for the nine months ended December 27, 2009 was favorably impacted by (i) higher income generated from our foreign operations, which are taxed at more favorable rates, (ii) the resolution of various federal, state and foreign tax matters, (iii) additional benefits related to research tax credits and (iv) an increase in tax benefits related to stock-based awards. Our effective income tax rate for the nine months ended December 28, 2008, was adversely impacted by a valuation allowance against deferred tax assets related to impairment charges on certain investment securities. Given the increased global scope of our operations, and the complexity of global tax and transfer pricing rules and regulations, it has become increasingly difficult to estimate earnings within each tax jurisdiction. If actual earnings within each tax jurisdiction differ materially from our estimates, we may not achieve our expected effective tax rate. Additionally, our effective tax rate may be impacted by other items including the tax effects of acquisitions, newly enacted tax legislation, stock-based compensation and uncertain tax positions.

Liquidity and Capital Resources
     Our combined balances of cash, cash equivalents and investment securities decreased to $349.2 million at December 27, 2009 from $378.3 million at March 29, 2009. The decrease in cash, cash equivalents and investment securities was due primarily to the purchase of our common stock pursuant to our stock repurchase program, purchases of property and equipment and the acquisition of NetXen, partially offset by cash generated from operations and net proceeds from the issuance of stock under our stock plans. We believe that existing cash, cash equivalents, investment securities and expected cash flow from operations will provide sufficient funds to finance our operations for at least the next twelve months. However, it is possible that we may need to supplement our existing sources of liquidity to finance our activities beyond the next twelve months or for the future acquisition of businesses, products or technologies and there can be no assurance that sources of liquidity will be available to us at that time.
     Cash provided by operating activities was $92.5 million for the nine months ended December 27, 2009 and $162.4 million for the nine months ended December 28, 2008. Operating cash flow for the nine months ended December 27, 2009 reflects our net income of $59.8 million and net non-cash charges of $61.1 million, partially offset by a net increase in the non-cash components of working capital of $28.4 million. The increase in the non-cash components of working capital was primarily due to a $19.4 million decrease in accrued taxes, a $17.4 million increase in accounts receivable and a $9.5 million decrease in accrued compensation, partially offset by a $19.5 million decrease in inventories. The decrease in accrued taxes and accrued compensation were primarily due to the timing of payment obligations. The increase in accounts receivable was primarily due to an increase in net revenues. The decrease in inventories was primarily associated with the completion of a planned contract manufacturer transition and higher product shipments.
     Cash used in investing activities was $57.1 million for the nine months ended December 27, 2009 and consisted of $38.2 million of net purchases of available-for-sale securities, $17.6 million of purchases of property and equipment and $14.9 million for the acquisition of NetXen (net of cash acquired), partially offset by $10.5 million of proceeds from redemptions of auction rate securities at par value and distributions totaling $3.1 million from our investments in a money market fund and enhanced cash fund sponsored by The Reserve (an asset management company). During the nine months ended December 28, 2008, cash used in investing activities was $27.5 million and consisted of a $57.2 million reclassification of certain cash equivalents to investment securities related to our investments in the funds sponsored by The Reserve and purchases of property and equipment of $21.4 million, partially offset by net sales and maturities of available-for-sale securities of $41.9 million, distributions totaling $6.5 million from our investments in the funds sponsored by The Reserve and $2.7 million of proceeds from redemptions of auction rate securities at par value.
     As our business grows, we expect capital expenditures to increase in the future as we continue to invest in machinery and equipment, more costly engineering and production tools for new technologies, and enhancements to our corporate information technology infrastructure.
     Cash used in financing activities of $93.9 million for the nine months ended December 27, 2009 consisted of our purchase of $109.0 million of common stock under our stock repurchase program, $2.8 million for minimum tax withholdings paid on behalf of employees for restricted stock units that vested during the period and the repayment of a $0.9 million line of credit assumed in the NetXen acquisition, partially offset by $18.8 million of net proceeds from the issuance of common stock under our stock plans and the related tax effect. During the nine months ended December 28, 2008, cash used in financing activities of $143.3 million consisted of our purchase of $165.2 million of common stock under our stock repurchase program and $2.0 million for minimum tax withholdings paid on behalf of employees for restricted stock units that vested during the period, partially offset by $23.9 million of net proceeds from the issuance of common stock under our stock plans and the related tax effect.
     As of December 27, 2009, our investment securities included $21.4 million of investments in ARS, the majority of which are rated AA or higher. During late fiscal 2008, the market auctions of many ARS began to fail, including auctions for our ARS. The underlying assets for auction rate debt securities in our portfolio are student loans, substantially all of which are backed by the federal government under the Federal Family Education Loan Program. The underlying assets of our auction rate preferred securities are the respective funds’ investment portfolios.
     In November 2008, we entered into an agreement with the broker for all of the ARS we currently hold, which provides us with certain rights (ARS Rights), in exchange for the release of potential claims and damages against the broker. The ARS Rights entitle us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, which price is referred to as “par.” The ARS Rights may be exercised by us at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold. Under the ARS Rights, the broker may, at its discretion, purchase the ARS at any time through July 2, 2012 without prior notice to us and must pay us par value for the ARS within one day of the sale transaction settlement. While we expect to ultimately recover our investments in the ARS at par, we may be unable to liquidate some

or all of our ARS should we need or desire to access the funds invested in those securities prior to redemption by the issuer or the exercise of the ARS Rights. There is also a risk that our broker will default on its obligation to purchase the ARS in the event that we exercise the ARS Rights.
     Our investment securities are valued based on quoted market prices or other observable market inputs, except for the ARS, the put options related to ARS, and investments accounted for under the cost method. As of December 27, 2009, the entire $21.4 million portfolio of ARS and the related put options valued at $3.0 million (collectively, 12% of our investment securities portfolio) were measured at fair value based primarily on an income approach using estimates of future cash flows. The assumptions used in preparing the discounted cash flow models included estimates for the amount and timing of future interest and principal payments, the collateralization of underlying security investments, the creditworthiness of the issuer and the rate of return required by investors to own these securities in the current environment, including call and liquidity premiums.
     Since fiscal 2003, we have had various stock repurchase programs that authorized the purchase of up to $1.55 billion of our outstanding common stock. As of December 27, 2009, we had repurchased a total of 89.5 million shares of our common stock under our stock repurchase programs for an aggregate purchase price of $1.39 billion. During the nine months ended December 27, 2009, we repurchased 7.0 million shares of our common stock for an aggregate purchase price of $108.7 million. Pursuant to the existing stock repurchase program, we are authorized to repurchase shares with an aggregate cost of up to $161.2 million as of December 27, 2009.
     We have certain contractual obligations and commitments to make future payments in the form of non-cancelable purchase orders to our suppliers and commitments under operating lease arrangements. A summary of our contractual obligations as of December 27, 2009, and their impact on our cash flows in future fiscal years, is as follows:
                                                         
    2010                                      
    (Remaining

    (In millions)  
Operating leases
  $ 2.3     $ 7.5     $ 5.3     $ 3.7     $ 3.5     $ 9.0     $ 31.3  
Non-cancelable purchase obligations

     The amount of unrecognized tax benefits, including related accrued interest and penalties, was $41.9 million at December 27, 2009. We are not able to provide a reasonable estimate of the timing of future tax payments related to these obligations.

Critical Accounting Policies and Estimates
     The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and judgments that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net revenues and expenses during the reporting period. We base our estimates on historical experience and on various other factors, including the current economic environment, which we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. We believe the accounting policies described below to be our most critical accounting policies. These accounting policies are affected significantly by judgments, assumptions and estimates used in the preparation of the financial statements and actual results could differ materially from the amounts reported based on these policies.
  Revenue Recognition
     We recognize revenue from product sales when the following fundamental criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the price to the customer is fixed or determinable and (iv) collection of the resulting accounts receivable is reasonably assured.
     For all sales, we use a binding purchase order or a signed agreement as evidence of an arrangement. Delivery occurs when goods are shipped and title and risk of loss transfer to the customer, in accordance with the terms specified in the arrangement with the customer. The customer’s obligation to pay and the payment terms are set at the time of delivery and are not dependent on the subsequent resale of our product. However, certain of our sales are made to distributors under agreements which contain a limited right to return unsold product and price protection provisions. We recognize revenue from these distributors based on the sell-through method using inventory information provided by the distributor. At times, we provide standard incentive programs to our customers. We account for our competitive pricing incentives, which generally reflect front-end price adjustments, as a reduction of revenue at the time of sale, and rebates as a reduction of revenue in the period the related revenue is recorded based on the specific program criteria and historical experience. In addition, we record provisions against revenue and cost of revenue for estimated product returns in the same period that revenue is recognized. These provisions are based on historical experience as well as specifically identified product returns. Royalty and service revenue is recognized when earned and receipt is reasonably assured.
     For those sales that include multiple deliverables, we allocate revenue based on the relative fair values of the individual components. When more than one element, such as hardware and services, are contained in a single arrangement, we allocate revenue between the elements based on each element’s relative fair value, provided that each element meets the criteria for treatment as a separate unit of accounting. An item is considered a separate unit of accounting if it has value to the customer on a standalone basis and there is objective and reliable evidence of the fair value of the undelivered items. Fair value is generally determined based upon the price charged when the element is sold separately. In the absence of fair value for a delivered element, we allocate revenue first to the fair value of the undelivered elements and allocate the residual revenue to the delivered elements. In the absence of fair value for an undelivered element, the arrangement is accounted for as a single unit of accounting, resulting in a deferral of revenue recognition for the delivered elements. Such deferred revenue is recognized over the service period or when all elements have been delivered.
     We sell certain software products and related post-contract customer support (PCS). We recognize revenue from software products when the following fundamental criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) the price to the customer is fixed or determinable and (iv) collection of the resulting accounts receivable is probable. Revenue is allocated to undelivered elements based upon vendor-specific objective evidence (VSOE) of the fair value of the element. VSOE of the fair value is based upon the price charged when the element is sold separately. Revenue allocated to each element is then recognized when the basic revenue recognition criteria are met for each element. If we are unable to determine VSOE of fair value for an undelivered element, the entire amount of revenue from the arrangement is deferred and recognized over the service period or when all elements have been delivered.
     An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of our customers to make required payments. This reserve is determined by analyzing specific customer accounts, applying estimated loss rates to the aging of remaining accounts receivable balances, and considering the impact of the current economic environment where appropriate. If the financial condition of our customers were to deteriorate, resulting in their inability to pay their accounts when due, additional reserves might be required.

  Stock-Based Compensation
     We recognize compensation expense for all stock-based payment awards made to employees and non-employee directors, including stock options, restricted stock units and stock purchases under our Employee Stock Purchase Plan (the ESPP), based on estimated fair values on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service period in our consolidated financial statements. Forfeitures are estimated at the time of grant based on historical trends and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We recognize stock-based compensation expense on a straight-line basis over the requisite service period, which is the vesting period for stock options and restricted stock units, and the offering period for the ESPP. The determination of fair value of stock-based awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. In estimating expected stock price volatility, we use a combination of both historical volatility, calculated based on the daily closing prices of our common stock over a period equal to the expected term of the option, and implied volatility, utilizing market data of actively traded options on our common stock. We believe that the historical volatility of the price of our common stock over the expected term of the option is a strong indicator of the expected future volatility. We also believe that implied volatility takes into consideration market expectations of how future volatility will differ from historical volatility. Accordingly, we believe a combination of both historical and implied volatility provides the best estimate of the future volatility of the market price of our common stock. Changes in the subjective assumptions can materially affect the estimated fair value of stock-based awards.
  Income Taxes
     We utilize the asset and liability method of accounting for income taxes. Income tax positions taken or expected to be taken in a tax return should be recognized in the first reporting period that it is more likely than not the tax position will be sustained upon examination. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. Previously recognized income tax positions that fail to meet the recognition threshold in a subsequent period are derecognized in that period. We recognize potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.
     Deferred income taxes are recognized for the future tax consequences of temporary differences using enacted statutory tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Temporary differences include the difference between the financial statement carrying amounts and the tax bases of existing assets and liabilities and operating loss and tax credit carryforwards. The effect on deferred taxes of a change in tax rates is recognized in earnings in the period that includes the enactment date.
     A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. An adjustment to earnings would occur if we determine that we are able to realize a different amount of our deferred tax assets than currently expected.
     As a multinational corporation, we are subject to complex tax laws and regulations in various jurisdictions. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws themselves are subject to change as a result of changes in fiscal policy, changes in legislation, evolution of regulations and court rulings. Therefore, the actual liability for U.S. or foreign taxes may be materially different from our estimates, which could result in the need to record additional liabilities or potentially to reverse previously recorded tax liabilities. Differences between actual results and our assumptions, or changes in our assumptions in future periods, are recorded in the period they become known.
  Investment Securities
     Our investment securities include available-for-sale securities, trading securities and other investment securities and are classified in the consolidated balance sheets based on the nature of the security and the availability for use in current operations.
     Our available-for-sale securities are recorded at fair value, based on quoted market prices or other observable inputs. Unrealized gains and losses, net of related income taxes, on our portfolio of available-for-sale securities are excluded from earnings and reported as a separate component of accumulated other comprehensive income until realized.

22


Table of Contents

     Our trading securities are recorded at fair value with unrealized holding gains and losses included in earnings and reported in interest and other income, net. In the absence of quoted market prices for trading securities, we value these securities based on an income approach using an estimate of future cash flows.
     Our other investment securities are accounted for under the cost method and recorded at the lower of fair value or cost.
     We recognize an impairment charge on our available-for-sale and cost method investments when the decline in the fair value of an investment below its cost basis is judged to be other-than-temporary. If we intend to sell the security or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, we would recognize the entire impairment in earnings. If we do not intend to sell the security and it is not more likely than not that we will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary impairment shall be separated into (a) the amount representing the credit loss and (b) the amount related to all other factors. The amount of the other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the other-than-temporary impairment related to other factors is recognized in other comprehensive income, net of applicable taxes. Significant judgment is required in determining the fair value of investment securities in inactive markets as well as determining when declines in fair value constitute an other-than-temporary impairment. We consider various factors in determining whether to recognize an impairment charge, including the current financial and credit market environment, the financial condition and near-term prospects of the issuer of the security, the magnitude of the loss compared to the cost of the investment, the length of time the investment has been in a loss position and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery of market value.
     Realized gains or losses are determined on a specific identification basis and reported in interest and other income, net, as incurred.
  Inventories
     Inventories are stated at the lower of cost (first-in, first-out) or market. We write down the carrying value of our inventory to estimated net realizable value for estimated excess and obsolete inventory based upon assumptions about future demand and market conditions. These assumptions are based on economic conditions and trends (both current and projected), anticipated customer demand and acceptance of our current products, expected future products and other assumptions. If actual market conditions are less favorable than those projected by management, additional write-downs may be required. Once we write down the carrying value of inventory, a new cost basis is established. Subsequent changes in facts and circumstances do not result in an increase in the newly established cost basis.
  Goodwill and Other Intangible Assets
     Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The amounts and useful lives assigned to intangible assets acquired, other than goodwill, impact the amount and timing of future amortization. The amount assigned to in-process research and development is capitalized and accounted for as an indefinite-lived intangible asset until the underlying projects are completed or abandoned.
     Goodwill is not amortized but instead is tested at least annually for impairment, or more frequently when events or changes in circumstances indicate a potential impairment, by comparing the carrying value to the fair value of the reporting unit to which the goodwill is assigned. A two-step test is used to identify the potential impairment and to measure the amount of impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit is less than its carrying amount, goodwill is considered impaired and the loss is measured by performing step two. Under step two, the impairment loss is measured by comparing the implied fair value of the reporting unit with the carrying amount of goodwill. We perform the annual test for impairment as of the first day of our fiscal fourth quarter.
     The initial recording and subsequent evaluation for impairment of goodwill and purchased intangible assets requires the use of significant management judgment regarding the forecasts of future operating results. It is possible that our business plans may change and our estimates used may prove to be inaccurate. If our actual results, or the plans and estimates used in future impairment analyses, are lower than current estimates used, we could incur impairment charges.

  Long-Lived Assets
     Long-lived assets, including property and equipment and purchased intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Significant judgment is required in determining whether a potential indicator of impairment of our long-lived assets exists and in estimating future cash flows for any necessary impairment tests. Recoverability of assets to be held and used is measured by the comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such an asset is considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Estimating future net cash flows and determining proper asset groupings for the purpose of this impairment test requires the use of significant management judgment. If our actual results, or estimates used in future impairment analyses, are lower than our current estimates, we could incur impairment charges.
  Recent Accounting Pronouncements
     In August 2009, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2009-5, which provides amendments to The FASB Accounting Standards Codification™ (ASC) Topic 820, “Fair Value Measurements and Disclosures.” ASU No. 2009-5 provides clarification for measuring fair value when a quoted price in an active market for the identical liability is not available. ASU No. 2009-5 also clarifies that 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. ASU No. 2009-5 was effective for fiscal periods beginning after August 27, 2009. We adopted ASU No. 2009-5 effective September 28, 2009 and it did not have a material impact on our consolidated results of operations or financial position.
     In September 2009, the FASB issued ASU No. 2009-13, which provides amendments to ASC Topic 605 “Multiple-Deliverable Revenue Arrangements.” ASU No. 2009-13 replaces and significantly changes certain guidance in ASC Topic 605. ASU No. 2009-13 modifies the separation criteria of ASC Subtopic 605-25 by eliminating the criterion for objective and reliable evidence of fair value for the undelivered products or services. Instead, revenue arrangements with multiple deliverables should be divided into separate units of accounting provided the deliverables meet certain criteria. ASU No. 2009-13 eliminates the use of the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables based on their relative selling price. ASU No. 2009-13 provides a hierarchy for estimating the selling price for each of the deliverables. ASU No. 2009-13 is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. We are currently assessing the impact ASU No. 2009-13 will have on our consolidated results of operations or financial position.
     In September 2009, the FASB issued ASU No. 2009-14, “Certain Revenue Arrangements That Include Software Elements.” Pursuant to ASU No. 2009-14, all tangible products containing both software and non-software components that function together to deliver the product’s essential functionality will no longer be within the scope of ASC Subtopic 985-605 and will be required to be accounted for under the guidance in ASU No. 2009-13. ASU No. 2009-14 provides a list of items to consider when determining whether the software and non-software components function together to deliver a product’s essential functionality. ASU No. 2009-14 is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. We are currently assessing the impact ASU No. 2009-14 will have on our consolidated results of operations or financial position.
     In January 2010, the FASB issued ASU No. 2010-06, which provides amendments to ASC Topic 820, “Fair Value Measurements and Disclosures.” ASU No. 2010-06 requires new fair value disclosures and clarifies certain existing disclosure requirements. ASU No. 2010-06 is effective for fiscal periods beginning after December 15, 2010 for the requirement to provide information on purchases, sales, issuances and settlements in the Level 3 rollforward on a gross basis. All other disclosure requirements under ASU No. 2010-06 are effective for fiscal periods beginning after December 15, 2009. We are currently assessing the impact ASU No. 2010-06 will have on our consolidated financial statements.

Item 3.   Quantitative and Qualitative Disclosures About Market Risk
     Our cash and cash equivalents are not subject to significant interest rate risk due to the short maturities of these instruments. As of December 27, 2009, the carrying value of our cash and cash equivalents approximates fair value.
     We maintain a portfolio of investment securities consisting primarily of debt securities, including government and agency securities, corporate debt obligations, asset and mortgage-backed securities, and municipal bonds, the majority of which have remaining terms of three years or less. We are exposed to fluctuations in interest rates as movements in interest rates can result in changes in the market value of our investments in debt securities. However, due to the short-term nature of our investment portfolio we do not believe that we are subject to material interest rate risk.
     In accordance with our investment guidelines, we only invest in instruments with high credit quality ratings and we limit our exposure to any one issuer or type of investment. Our portfolio of investment securities as of December 27, 2009 includes $179.1 million of securities that are classified as available for sale. As of December 27, 2009, we had gross unrealized losses associated with our available-for-sale securities of $0.1 million that were determined by management to be temporary in nature.
     Our portfolio of investment securities as of December 27, 2009 also includes $17.1 million of auction rate debt securities and $4.3 million of auction rate preferred securities (collectively, ARS), the majority of which are rated AA or higher, and related put options valued at $3.0 million. These investment securities are accounted for as trading securities. During late fiscal 2008, the market auctions of many ARS began to fail, including auctions for our ARS. The underlying assets for auction rate debt securities in our portfolio are student loans, substantially all of which are backed by the federal government under the Federal Family Education Loan Program. The underlying assets of our auction rate preferred securities are the respective funds’ investment portfolios.
     In November 2008, we entered into an agreement with the broker for all of the ARS we currently hold, which provides us with certain rights (ARS Rights), in exchange for the release of potential claims and damages against the broker. The ARS Rights entitle us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, which price is referred to as “par.” The ARS Rights may be exercised by us at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold. Under the ARS Rights, the broker may, at its discretion, purchase the ARS at any time through July 2, 2012 without prior notice to us and must pay us par value for the ARS within one day of the sale transaction settlement. While we expect to ultimately recover our investments in the ARS at par, we may be unable to liquidate some or all of our ARS should we need or desire to access the funds invested in those securities prior to redemption by the issuer or the exercise of the ARS Rights. There is also a risk that our broker will default on its obligation to purchase the ARS in the event that we exercise the ARS Rights.
     Based on our existing cash, cash equivalents and investment securities, as well as our expected cash flows from operating activities, we do not anticipate that the potential lack of liquidity of our ARS in the near-term will affect our ability to execute our current business plan.
     We do not use derivative financial instruments.

Item 4. Controls and Procedures
     We maintain disclosure controls and procedures to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934, as amended, (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 chief financial officer, to allow timely decisions regarding required disclosure. Our management evaluated, with the participation of our chief executive officer and chief financial officer, the effectiveness of our disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures were effective as of December 27, 2009. There was no change in our internal control over financial reporting during our quarter ended December 27, 2009 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II.
OTHER INFORMATION
Item 1A. Risk Factors
     We have updated the risk factors discussed in Item 1A of our Annual Report on Form 10-K for the year ended March 29, 2009, as set forth below. We do not believe any of the updates constitute material changes from the risk factors previously discussed in our Annual Report on Form 10-K for the year ended March 29, 2009.
Economic weakness and uncertainty has resulted in a decrease in IT spending levels and could result in further deterioration of our revenues and operating results.
     The United States and other countries around the world have been experiencing economic weakness and uncertainty. There has been an erosion of global consumer confidence amidst concerns over declining asset values, inflation, energy costs, geopolitical issues, the availability and cost of credit, rising unemployment, and the stability and solvency of financial institutions, financial markets, businesses and sovereign nations. We are unable to predict the likely duration and severity of the disruption in financial markets and adverse economic conditions in the U.S. and other countries. The economic decline has resulted in a global downturn in information technology, or IT, spending rates, which has negatively impacted our revenue and operating results. Further reductions in IT spending rates could result in longer sales cycles, increased inventory provisions, increased production costs, lower prices for our products and reduced sales volumes. Even if IT spending rates were to increase, we cannot be certain that the market for storage and server networking infrastructure solutions would be positively impacted. If economic conditions worsen, there are future reductions in either domestic or international IT spending rates, or IT spending rates do not increase, our revenues, operating results and financial condition could deteriorate further.
     As a result of worldwide economic uncertainty, it is extremely difficult for us and our customers to forecast future revenue levels based on historical information and trends. Portions of our expenses are fixed and other expenses are tied to expected levels of revenue. To the extent that we do not achieve our anticipated level of revenue, our operating results could be adversely affected until such expenses are reduced to an appropriate level. In addition, we have implemented various cost-cutting measures in order to better align our revenues and cost structure. We may not be able to identify and implement appropriate further cost savings in a timely manner. Additionally, we may determine that the costs of implementing reductions outweigh the commensurate benefits. Should we implement certain cost reductions, there could be adverse consequences on our business which could have a material adverse effect on our results of operations or financial condition.
     We are also subject to various counterparty risks as a result of the economic slowdown, including the potential insolvency of key suppliers resulting in product delays, inability of customers to obtain credit to finance purchases of our products and/or potential customer insolvencies, increased risk that customers may delay payments or fail to pay, and counterparty failures, particularly financial institutions, negatively impacting our treasury operations. Any of these risks could have a material adverse effect on our results of operations or financial condition.
Our operating results may fluctuate in future periods, which could cause our stock price to decline.
     We have experienced, and expect to experience in future periods, fluctuations in sales and operating results from quarter to quarter. In addition, there can be no assurance that we will maintain our current gross margins or profitability in the future. A significant portion of our net revenues in each fiscal quarter results from orders booked in that quarter. Orders placed by major customers are typically based on their forecasted sales and inventory levels for our products.
     Fluctuations in our quarterly operating results may also be the result of:
  the timing, size and mix of orders from customers;
 
  gain or loss of significant customers;
 
  customer policies pertaining to desired inventory levels of our products;
 
  negotiated rebates and extended payment terms;
 
  changes in our ability to anticipate in advance the mix of customer orders;

  levels of inventory our customers require us to maintain in our inventory hub locations;
 
  the availability and sale of new products;
 
  shifts or changes in technology;
 
  changes in the mix or average selling prices of our products;
 
  variations in manufacturing capacities, efficiencies and costs;
 
  the availability and cost of components, including silicon chips;
 
  variations in product development costs, especially related to advanced technologies;
 
  variations in operating expenses;
 
  changes in effective income tax rates, including those resulting from changes in tax laws;
 
  our ability to timely produce products that comply with new environmental restrictions or related requirements of our original equipment manufacturer, or OEM, customers;
 
  actual events, circumstances, outcomes and amounts differing from judgments, assumptions and estimates used in determining the value of certain assets (including the amounts of related valuation allowances), liabilities and other items reflected in our consolidated financial statements;
 
  the timing of revenue recognition and revenue deferrals;
 
  gains or losses related to our investment securities;
 
  changes in accounting rules;
 
  changes in our accounting policies;
 
  general economic and other conditions affecting the timing of customer orders and capital spending; or
 
  changes in the global economy that impact IT spending.
     In addition, our quarterly results of operations are influenced by competitive factors, including the pricing and availability of our products and our competitors’ products. Furthermore, communications regarding new products and technologies could cause our customers to defer or cancel purchases of our products. Order deferrals by our customers, delays in our introduction of new products, and longer than anticipated design-in cycles for our products have in the past adversely affected our quarterly results of operations. Due to these factors, as well as other unanticipated factors, it is likely that in some future quarter or quarters our operating results will be below the expectations of public market analysts or investors, and as a result, the price of our common stock could significantly decrease.
We expect gross margin to vary over time, and our recent level of gross margin may not be sustainable.
     Our recent level of gross margin may not be sustainable and may be adversely affected by numerous factors, including:
  changes in product mix;
 
  changes in manufacturing volumes over which fixed costs are absorbed;
 
  increased price competition;
 
  introduction of new products by us or our competitors, including products with advantages in price, performance or features;
 
  our inability to reduce manufacturing-related or component costs;

  entry into new markets or the acquisition of new businesses;
 
  amortization and impairments of purchased intangible assets;
 
  sales discounts and customer incentives;
 
  increases in material, labor or overhead costs;
 
  excess inventory and inventory holding charges;
 
  changes in distribution channels;
 
  increased warranty costs; and
 
  how well we execute our business strategy and operating plans.
Our stock price may be volatile.
     The market price of our common stock has fluctuated substantially, and there can be no assurance that such volatility will not continue. Several factors could impact our stock price including, but not limited to:
  differences between our actual revenues and operating results and the published expectations of analysts;
 
  quarterly fluctuations in our revenues and operating results;
 
  introduction of new products or changes in product pricing policies by our competitors or us;
 
  conditions in the markets in which we operate;
 
  changes in market projections by industry forecasters;
 
  changes in estimates of our earnings by industry analysts;
 
  operating results or forecasts of our major customers or competitors;
 
  overall market conditions for high technology equities;
 
  rumors or dissemination of false information; and
 
  general economic and geopolitical conditions.
     In addition, stock markets have experienced extreme price and volume volatility in recent years and stock prices of technology companies have been especially volatile. This volatility has had a substantial effect on the market prices of securities of many public companies for reasons frequently unrelated to the operating performance of the specific companies. These broad market fluctuations could adversely affect the market price of our common stock.
Our business is dependent, in large part, on the continued growth of the networking markets that we serve and if these markets do not continue to develop, our business will suffer.
     A significant number of our products are used in storage area networks, or SANs, and server networks. Therefore, our business is dependent on the SAN and server network infrastructure markets. Our success in generating revenue in these markets will depend on, among other things, our ability to:
  educate potential OEM customers, distributors, resellers, system integrators, storage system providers and end-user organizations about the benefits of our products;

29


Table of Contents

  maintain and enhance our relationships with OEM customers, distributors, resellers, system integrators and storage system providers;
 
  predict and base our products on standards which ultimately become industry standards; and
 
  achieve interoperability between our products and other components from diverse vendors.
Our business could be adversely affected by the broad adoption of server virtualization technology.
     Server virtualization technologies, which allow a single server to handle the function that was previously performed by many individual servers, are gaining momentum in the industry. The broad implementation of server virtualization could result in a decrease in the demand for servers, which could result in a lower demand for our products. This could have a material adverse effect on our business or results of operations.
     Our business could be adversely affected by a significant increase in the market acceptance of blade servers.
     Blade server products have gained acceptance in the market over the past few years. Blade servers use custom SAN infrastructure products, including blade switches and mezzanine cards, which have lower average selling prices than the SAN infrastructure products used in a non-blade server environment. If blade servers gain an increased percentage of the overall server market, our business could be adversely affected by the transition to blade server products. This could have a material adverse effect on our business or results of operations.
Our financial condition will be materially harmed if we do not maintain and gain market acceptance of our products.
     The markets in which we compete involve rapidly changing technology, evolving industry standards and continuing improvements in products and services. Our future success depends, in part, on our ability to:
  enhance our current products and develop and introduce in a timely manner new products that keep pace with technological developments and industry standards;
 
  compete effectively on the basis of price and performance; and
 
  adequately address OEM and end-user customer requirements and achieve market acceptance.
     We believe that to remain competitive, we will need to continue to develop new products, which will require a significant investment. Our competitors may be developing alternative technologies, which may adversely affect the market acceptance of our products. Although we continue to explore and develop products based on new technologies, a substantial portion of our revenues is generated today from Fibre Channel technology. If alternative technologies are adopted by the industry, we may not be able to develop products for new technologies in a timely manner. Further, even if alternative technologies do augment Fibre Channel revenues, our products may not be fully developed in time to be accepted by our customers. Even if our new products are developed on time, we may not be able to manufacture them at competitive prices or in sufficient volumes.
     We recently began shipping products based on the Fibre Channel over Ethernet, or FCoE, protocol. FCoE is a developing converged networking technology that provides a unified storage and data network over enhanced Ethernet, while preserving the investment in existing Fibre Channel infrastructure and storage. As with most emerging technologies, it is expected that the market for FCoE will take a number of years to develop and mature. We expect products based on the FCoE protocol to supplement, and perhaps replace, certain products based on the Fibre Channel protocol. As a result, an inability to maintain our market share in the Fibre Channel market and build upon our market share in the FCoE market could have a material adverse effect on our business or results of operations.
We depend on a small number of customers, and any decrease in revenues or cash flows from any one of our major customers could adversely affect our results of operations and cause our stock price to decline.
     A small number of customers account for a substantial portion of our net revenues, and we expect that a small number of customers will continue to represent a substantial portion of our net revenues in the foreseeable future. Our top ten customers accounted for 88% and 83% of net revenues for the nine months ended December 27, 2009 and December 28, 2008, respectively. We

are also subject to credit risk associated with the concentration of our accounts receivable. In addition, the worldwide economic slowdown and tightening of credit in financial markets may impact the businesses of our customers, which could have a material adverse effect on our business, financial condition or results of operations.
     Our customers generally order products through written purchase orders as opposed to long-term supply contracts and, therefore, are generally not obligated to purchase products from us for any extended period. Major customers also have significant leverage over us and may attempt to change the terms, including pricing and payment terms, which could have a material adverse effect on our business, financial condition or results of operations. This risk is increased due to the potential for some of these customers to merge with or acquire one or more of our other customers. As our OEM customers are pressured to reduce prices as a result of competitive factors, we may be required to contractually commit to price reductions for our products before we know how, or if, cost reductions can be obtained. If we are unable to achieve such cost reductions, our gross margins could decline and such decline could have a material adverse effect on our business, financial condition or results of operations.
Our business may be subject to seasonal fluctuations and uneven sales patterns in the future.
     A large percentage of our products are sold to customers who experience seasonality and uneven sales patterns in their businesses. As a result, we may experience similar seasonality and uneven sales patterns. We believe this uneven sales pattern is a result of many factors including:
  the tendency of our customers to close a disproportionate percentage of their sales transactions in the last month, weeks and days of each quarter;
 
  spikes in sales during the fourth quarter of each calendar year that some of our customers experience; and
 
  differences between our quarterly fiscal periods and the fiscal periods of our customers.
     In addition, as our customers increasingly require us to maintain products at hub locations near their facilities, it becomes increasingly difficult for us to predict sales trends. Our uneven sales pattern also makes it extremely difficult to predict the demand of our customers and adjust manufacturing capacity accordingly. If we predict demand that is substantially greater than actual customer orders, we will have excess inventory. Alternatively, if customer orders substantially exceed predicted demand, the ability to assemble, test and ship orders received in the last weeks and days of each quarter may be limited, or at an increased cost, which could have a material adverse effect on quarterly revenues and earnings.
Competition within the markets for our products is intense and includes various established competitors.
     The markets for our products are highly competitive and are characterized by short product life cycles, price erosion, rapidly changing technology, frequent product improvements and evolving industry standards. In the traditional Fibre Channel adapter market, we compete primarily with Emulex Corporation, followed by Brocade Communications Systems, Inc. In the iSCSI adapter market, we compete primarily with Chelsio Communications, Inc. and we also compete with companies offering software initiator solutions. In the FCoE adapter market, we compete with traditional Fibre Channel players like Emulex Corporation and Brocade Communications Systems, Inc., as well as Ethernet adapter suppliers such as Broadcom Corporation and Intel Corporation. In the Intelligent Ethernet adapter market, we compete with Intel Corporation, Broadcom Corporation and Emulex Corporation. In the Fibre Channel switch and storage router markets, we compete primarily with Brocade Communications Systems, Inc. and Cisco Systems, Inc. Our competition in the Fibre Channel switch market includes well-established participants who have significantly more sales and marketing resources to develop and penetrate this market. In the InfiniBand adapter and switch markets, we compete primarily with Voltaire Ltd. and Mellanox Technologies, Ltd. We may also compete with some of our server and storage systems customers, some of which have the capability to develop products comparable to those we offer.
     We need to continue to develop products appropriate to our markets to remain competitive as our competitors continue to introduce products with improved features. While we continue to devote significant resources to engineering and development, these efforts may not be successful or competitive products may not be developed and introduced in a timely manner. In addition, while relatively few competitors offer a full range of storage and server networking infrastructure products, additional domestic and foreign manufacturers may increase their presence in these markets. We may not be able to compete successfully against these or other competitors. If we are unable to design, develop or introduce competitive new products on a timely basis, our future operating results may be materially and adversely affected.

We expect the pricing of our products to continue to decline, which could reduce our revenues, gross margins and profitability.
     We expect the average unit prices of our products (on a like-for-like product comparison basis) to decline in the future as a result of competitive pricing pressures, increased sales discounts and customer incentives, new product introductions by us or our competitors, or other factors. In addition, there is a general market trend of customers migrating away from the distribution channel for product purchases to OEMs, where products have a lower average unit price. If we are unable to offset these factors by increasing sales volumes, or reducing product manufacturing costs, our total revenues and gross margins may decline. In addition, we must develop and introduce new products and product enhancements. Moreover, most of our expenses are fixed in the short-term or incurred in advance of receipt of corresponding revenues. As a result, we may not be able to decrease our spending to offset any unexpected shortfall in revenues. If this occurs, our operating results and gross margins may be below our expectations and the expectations of investors and public market analysts, and our stock price could be negatively affected.
Our distributors may not adequately stock and sell our products and their reseller customers may purchase products from our competitors, which could negatively affect our results of operations.
     Our distributors generally offer a diverse array of products from several different manufacturers and suppliers. Accordingly, we are at risk that these distributors may give higher priority to stocking and selling products from other suppliers, thus reducing their efforts and ability to sell our products. A reduction in sales efforts by our current distributors could materially and adversely impact our business or results of operations. In addition, if we decrease our distributor-incentive programs (i.e., competitive pricing and rebates), our distributors may decrease the amount of product purchased from us. This could result in a change of business behavior, and distributors may decide to decrease the amount of product held and reduce their inventory levels, which could impact availability of our products to their customers.
     As a result of these factors regarding our distributors or other unrelated factors, the reseller customers of our distributors could decide to purchase products developed and manufactured by our competitors. Any loss of demand for our products by value-added resellers and system integrators could have a material adverse effect on our business or results of operations.
We are dependent on sole source and limited source suppliers for certain key components.
     We purchase certain key components used in the manufacture of our products from single or limited sources. We purchase application-specific integrated circuits, or ASICs, from single sources and we purchase microprocessors, certain connectors, logic chips, power supplies and programmable logic devices from limited sources. If one of these suppliers experiences an interruption in its ability to supply our needs, or chooses to sever their relationship with us, we may be unable to produce certain of our products, which could result in the loss of customers and have a material adverse effect on our results of operations. The global economic downturn and tightening of credit in financial markets may adversely impact our suppliers by limiting their ability to finance their business operations and as a result limit their ability to supply products to us.
We are dependent on worldwide third-party subcontractors and contract manufacturers.
     Third-party subcontractors located outside the United States assemble and test certain products for us. To the extent that we rely upon third-party subcontractors to perform these functions, we will not be able to directly control product delivery schedules and quality assurance. This lack of control may result in product shortages or quality assurance problems that could delay shipments of products or increase manufacturing, assembly, testing or other costs. If any of these subcontractors experience capacity constraints or financial difficulties, suffer damage to their facilities, experience power outages or any other disruption of assembly or testing capacity, we may not be able to obtain alternative assembly and testing services in a timely manner.
     In addition, the loss of any of our major third-party contract manufacturers could significantly impact our ability to produce products for an indefinite period of time. Qualifying a new contract manufacturer and commencing volume production is a lengthy and expensive process. Some customers will not purchase any products, other than a limited number of evaluation units, until they qualify the manufacturing line for the product, and we may not always be able to satisfy the qualification requirements of these customers. If we are required to change a contract manufacturer or if a contract manufacturer experiences delays, disruptions, capacity constraints, component parts shortages or quality control problems in its manufacturing operations, shipment of our products to our customers could be delayed, resulting in loss or postponement of revenues and potential harm to our competitive position and relationship with customers. In addition, the global economic downturn and tightening of credit markets could adversely affect our

32

third-party subcontractors or contract manufacturers and increase the potential for one or more of them to experience financial distress or bankruptcy.
Our investment securities portfolio could experience a decline in market value which could materially and adversely affect our financial results.
     As of December 27, 2009, we held short-term investment securities totaling $204.1 million. We invest primarily in debt securities, the majority of which are high investment grade, and we limit the exposure to credit risk through diversification and investment in highly-rated securities. However, investing in highly-rated securities does not entirely mitigate the risk of potential declines in market value. During fiscal 2009, we recorded impairment charges related to investment securities, including securities issued by companies in the financial services sector that had previously been rated AA or higher. A further deterioration in the economy, including further tightening of credit markets or significant volatility in interest rates, could cause additional declines in value of our investment securities or could impact the liquidity of the portfolio. If market conditions deteriorate significantly, our results of operations or financial condition could be materially and adversely affected.
     Our investment securities include $21.4 million of investments in auction rate debt and preferred securities (ARS), the majority of which are rated AA or higher. During late fiscal 2008, the market auctions of many ARS began to fail, including auctions for our ARS. The underlying assets for auction rate debt securities in our portfolio are student loans, substantially all of which are backed by the federal government under the Federal Family Education Loan Program. The underlying assets of our auction rate preferred securities are the respective funds’ investment portfolios.
     In November 2008, we entered into an agreement with the broker for all of the ARS we currently hold, which provides us with certain rights (ARS Rights), in exchange for the release of potential claims and damages against the broker. The ARS Rights entitle us to sell the related ARS back to the broker for a price equal to the liquidation preference of the ARS plus accrued but unpaid dividends or interest, if any, which price is referred to as “par.” The ARS Rights may be exercised by us at any time between June 30, 2010 and July 2, 2012, if the securities are not earlier redeemed or sold. Under the ARS Rights, the broker may, at its discretion, purchase the ARS at any time through July 2, 2012 without prior notice to us and must pay us par value for the ARS within one day of the sale transaction settlement. While we expect to ultimately recover our investments in the ARS at par, we may be unable to liquidate some or all of our ARS should we need or desire to access the funds invested in those securities prior to redemption by the issuer or the exercise of the ARS Rights. There is also a risk that our broker will default on its obligation to purchase the ARS in the event that we exercise the ARS Rights.
Our products are complex and may contain undetected software or hardware errors that could lead to an increase in our costs, reduce our net revenues or damage our reputation.
     Our products are complex and may contain undetected software or hardware errors when first introduced or as newer versions are released. We are also exposed to risks associated with latent defects in existing products. From time to time, we have found errors in existing, new or enhanced products. In addition, our products are frequently combined with other products, including software, from other vendors, and these products often need to interface with existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. As a result, when problems occur, it may be difficult to identify the source of the problem. The occurrence of hardware or software errors could adversely affect the sales of our products, cause us to incur significant warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems.
The migration of our customers toward new products could adversely affect our results of operations.
     As new or enhanced products are introduced, we must successfully manage the transition from older products in order to minimize the effects of product inventories that may become excess and obsolete, as well as ensure that sufficient supplies of new products can be delivered to meet customer demand. Our failure to manage the transition to newer products in the future or to develop and successfully introduce new products and product enhancements could adversely affect our business or results of operations. When we introduce new products and product enhancements, we face risks relating to product transitions, including risks relating to forecasting demand. Any such adverse event could have a material adverse effect on our business, financial condition or results of operations.

     Historically, the technology industry has developed higher performance ASICs, which create chip-level solutions that replace selected board-level or box-level solutions at a significantly lower average selling price. We have previously offered ASICs to customers for certain applications that have effectively resulted in a lower-priced solution when compared to an adapter solution. This transition to ASICs may also occur with respect to other current and future products. The result of this transition may have an adverse effect on our business, financial condition or results of operations. In the future, a similar adverse effect to our business could occur if there were rapid shifts in customer purchases from our midrange server and storage solutions to products for the small and medium-sized business market or if our customers shifted to lower-cost products that could replace our adapter solutions.
Unanticipated changes in our tax provisions or adverse outcomes resulting from examination of our income tax returns could adversely affect our results of operations.
     We are subject to income taxes in the United States and various foreign jurisdictions. Our effective income tax rates have recently been and could in the future be adversely affected by changes in tax laws or interpretations of those tax laws, by changes in the mix of earnings in countries with differing statutory tax rates, by discovery of new information in the course of our tax return preparation process, or by changes in the valuation of our deferred tax assets and liabilities. Our effective income tax rates are also affected by intercompany transactions for licenses, services, funding and other items. Given the increased global scope of our operations, and the complexity of global tax and transfer pricing rules and regulations, it has become increasingly difficult to estimate earnings within each tax jurisdiction. If actual earnings within a tax jurisdiction differ materially from our estimates, we may not achieve our expected effective tax rate. Additionally, our effective tax rate may be impacted by the tax effects of acquisitions, newly enacted tax legislation, stock-based compensation and uncertain tax positions. Finally, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities which may result in the assessment of additional income taxes. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. However, unanticipated outcomes from these continuous examinations could have a material adverse effect on our financial condition or results of operations.
Environmental compliance costs could adversely affect our results of operations.
     We are subject to various federal, state, local and foreign laws concerning environmental protection, including laws addressing the discharge of pollutants into the environment, the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites, the content of our products and the recycling, treatment and disposal of our products. In particular, we face increasing complexity in our product design and procurement operations as we adjust to new and future requirements relating to the chemical and material composition of our products, their safe use, the energy consumption associated with those products and product take-back legislation (i.e., legislation that makes producers of electrical goods financially responsible for specified collection, recycling, treatment and disposal of past and future covered products). We could incur substantial costs, our products could be restricted from entering certain jurisdictions, and we could face other sanctions, if we were to violate or become liable under environmental laws or if our products become non-compliant with environmental laws. Our potential exposure includes fines and civil or criminal sanctions, third-party property damage or personal injury claims, and clean up costs. Further, liability under some environmental laws relating to contaminated sites can be imposed retroactively, on a joint and several basis, and without any finding of noncompliance or fault. The amount and timing of costs under environmental laws are difficult to predict.
Because we have operations in foreign countries and depend on foreign customers and suppliers, we are subject to international economic, currency, regulatory, political and other risks that could harm our business, financial condition and results of operations.
     International revenues accounted for 54% and 52% of our net revenues for the nine months ended December 27, 2009 and December 28, 2008, respectively. We expect that international revenues will continue to account for a significant percentage of our net revenues for the foreseeable future. In addition, we maintain operations in foreign countries and a significant portion of our inventory purchases are from suppliers that are located outside the United States. As a result, we are subject to several risks, which include:
    a greater difficulty of administering and managing our business globally;
 
    compliance with multiple and potentially conflicting regulatory requirements, such as import or export requirements, tariffs and other barriers;
 
    less effective intellectual property protections;

34


Table of Contents

    potentially longer accounts receivable collection cycles;
 
    currency fluctuations;
 
    overlapping or differing tax structures;
 
    potential restrictions on transferring funds between countries and difficulties associated with repatriating cash generated or held outside of the U.S. in a tax-efficient manner;
 
    political and economic instability, including terrorism and war; and
 
    general trade restrictions.
     Our international sales are invoiced in U.S. dollars and, accordingly, if the relative value of the U.S. dollar in comparison to the currency of our foreign customers should increase, the resulting effective price increase of our products to such foreign customers could result in decreased sales. Any of the foregoing factors could have a material adverse effect on our business, financial condition or results of operations.
     In addition, we and our customers are subject to various import and export regulations of the United States government and other countries. Certain government export regulations apply to the encryption or other features contained in some of our products. Changes in or violations of any such import or export regulations could materially and adversely affect our business, financial condition or results of operations.
     Moreover, in many foreign countries, particularly in those with developing economies, it is common to engage in business practices that are prohibited by regulations applicable to us, such as the Foreign Corrupt Practices Act. Although we implement policies and procedures designed to ensure compliance with these laws, our employees, contractors and agents, as well as those companies to which we outsource certain of our business operations, may take actions in violation of our policies. Any such violation, even if prohibited by our policies, could have a material adverse effect on our business, financial condition or results of operations.
We may engage in mergers, acquisitions and strategic investments and these activities may adversely affect our results of operations and stock price.
     Our future growth may depend in part on our ability to identify and acquire complementary businesses, technologies or product lines that are compatible with our existing business. Mergers and acquisitions involve numerous risks, including:
    the failure of markets for the products of acquired companies to develop as expected;
 
    uncertainties in identifying and pursuing target companies;
 
    difficulties in the assimilation of the operations, technologies and products of the acquired companies;
 
    the existence of unknown defects in acquired companies’ products or assets that may not be identified due to the inherent limitations involved in the due diligence process of an acquisition;
 
    the diversion of management’s attention from other business concerns;
 
    risks associated with entering markets or conducting operations with which we have no or limited direct prior experience;
 
    risks associated with assuming the legal obligations of acquired companies;
 
    risks related to the effect that acquired companies’ internal control processes might have on our financial reporting and management’s report on our internal control over financial reporting;
 
    the potential loss of, or impairment of our relationships with, current customers or failure to retain the acquired companies’ customers;

35


Table of Contents

    the potential loss of key employees of acquired companies; and
 
    the incurrence of significant exit charges if products or technologies acquired in business combinations are unsuccessful.
     Further, we may never realize the perceived benefits of a business combination. Acquisitions by us could negatively impact gross margins or dilute stockholders’ investment and cause us to incur debt, contingent liabilities and amortization/impairment charges related to intangible assets, all of which could materially and adversely affect our financial position or results of operations. In addition, our effective tax rate for future periods could be negatively impacted by mergers and acquisitions.
If we are unable to attract and retain key personnel, we may not be able to sustain or grow our business.
     Our future success largely depends on our key engineering, sales, marketing and executive personnel, including highly skilled semiconductor design personnel and software developers, and in particular, our Chief Executive Officer, H.K. Desai. If we lose the services of Mr. Desai or other key personnel or fail to hire personnel for key positions, our business could be adversely affected. We believe that the market for key personnel in the industries in which we compete is highly competitive. In particular, periodically we have experienced difficulty in attracting and retaining qualified engineers and other technical personnel and anticipate that competition for such personnel will increase in the future. Our recent implementation of various cost saving measures, as well as past reductions in force, could negatively impact employee morale and potentially make attracting and retaining qualified employees more difficult in the future. As a result, we may not be able to attract and retain key personnel with the skills and expertise necessary to develop new products in the future or to manage our business, both in the United States and abroad.
     We have historically used stock options and other forms of stock-based compensation as key components of our total employee compensation program in order to align employees’ interests with the interests of our stockholders, encourage retention of key personnel, and provide competitive compensation packages. Moreover, applicable stock exchange listing standards relating to obtaining stockholder approval of equity compensation plans could make it more difficult or expensive for us to grant stock-based awards to employees in the future, which may result in changes in our stock-based compensation strategy. These and other developments relating to the provision of stock-based compensation to employees could make it more difficult to attract, retain and motivate key personnel.
We may experience difficulties in transitioning to smaller geometry process technologies.
     We expect to continue to transition our semiconductor products to increasingly smaller line width geometries. This transition requires us to modify the manufacturing processes for our products and to redesign some products as well as standard cells and other integrated circuit designs that we may use in multiple products. We periodically evaluate the benefits, on a product-by-product basis, of migrating to smaller geometry process technologies. Currently, most of our products include ASICs which are manufactured in 180, 130, 90 and 65 nanometer geometry processes. In addition, we continually evaluate smaller geometries. In the past, we have experienced some difficulties in shifting to smaller geometry process technologies or new manufacturing processes, which resulted in reduced manufacturing yields, delays in product deliveries and increased expenses. We may face similar difficulties, delays and expenses as we continue to transition our products to smaller geometry processes.
Our proprietary rights may be inadequately protected and difficult to enforce.
     In some jurisdictions, we have patent protection on certain aspects of our technology. However, we rely primarily on trade secrets, trademarks, copyrights and contractual provisions to protect our proprietary rights. There can be no assurance that these protections will be adequate to protect our proprietary rights, that others will not independently develop or otherwise acquire equivalent or superior technology, or that we can maintain such technology as trade secrets. There also can be no assurance that any patents we possess will not be invalidated, circumvented or challenged. We have taken steps in several jurisdictions to enforce our trademarks against third parties. No assurances can be given that we will ultimately be successful in protecting our trademarks. The laws of certain countries in which our products are or may be developed, manufactured or sold, including various countries in Asia, may not protect our products and intellectual property rights to the same extent as the laws of the United States, or at all. If we fail to protect our intellectual property rights, our business could be negatively impacted.
Disputes relating to claimed infringement of intellectual property rights may adversely affect our business.
     We have received notices of claimed infringement of intellectual property rights in the past and have been involved in intellectual property litigation in the past. There can be no assurance that third parties will not assert future claims of infringement of intellectual

36


Table of Contents

property rights against us, or against customers who we are contractually obligated to indemnify, with respect to existing and future products. In addition, individuals and groups are purchasing intellectual property assets for the sole purpose of making claims of infringement and attempting to extract settlements from companies such as ours. Although patent and intellectual property disputes may be settled through licensing or similar arrangements, costs associated with these arrangements may be substantial and the necessary licenses or similar arrangements may not be available to us on satisfactory terms, or at all. As a result, we could be prevented from manufacturing and selling some of our products. In addition, if we litigate these kinds of claims, the litigation could be expensive, time consuming and could divert management’s attention from other matters and there is no guarantee we would prevail. Our business could suffer regardless of the outcome of the litigation. Our supply of silicon chips and other components can also be interrupted by intellectual property infringement claims against our suppliers.
If we fail to carefully manage the use of “open source” software in our products, we may be required to license key portions of our products on a royalty-free basis or expose key parts of source code.
     Certain of our software may be derived from “open source” software that is generally made available to the public by its authors and/or other third parties. Such open source software is often made available to us under licenses, such as the GNU General Public License (GPL) which impose certain obligations on us in the event we were to distribute derivative works of the open source software. These obligations may require us to make source code for the derivative works available to the public, and/or license such derivative works under a particular type of license, rather than the forms of licenses customarily used to protect our intellectual property. In the event the copyright holder of any open source software were to successfully establish in court that we had not complied with the terms of a license for a particular work, we could be required to release the source code of that work to the public and/or stop distribution of that work.
Our business could be materially adversely affected by changes in regulations or standards regarding energy use of our products.
     We continually seek ways to increase the energy efficiency of our products. Recent analyses have estimated the amount of global carbon emissions that are due to information technology products. As a result, governmental and non-governmental organizations have turned their attention to development of regulations and standards to drive technological improvements and reduce such amount of carbon emissions. There is a risk that the rush to development of these standards will not fully address the complexity of the technology developed by the IT industry or will favor certain technological approaches. Depending on the regulations or standards that are ultimately adopted, compliance could adversely affect our business, results of operations or financial condition.
Computer viruses and other forms of tampering with our computer systems or servers may disrupt our operations and adversely affect our results of operations.
     Despite our implementation of network security measures and anti-virus defenses, our servers are vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. Any such event could have a material adverse effect on our business, results of operations or financial condition.
Our facilities and the facilities of our suppliers and customers are located in regions that are subject to natural disasters.
     Our California facilities, including our principal executive offices, our principal design facilities and our critical business operations, are located near major earthquake faults. We are not specifically insured for earthquakes or other natural disasters. Any personal injury or damage to the facilities as a result of such occurrences could have a material adverse effect on our business, results of operations or financial condition. Additionally, we have operations, suppliers and customers in regions which have historically experienced natural disasters. Any earthquake or other natural disaster, including a hurricane, tsunami or fire, affecting any of these regions could adversely affect our business, results of operations and financial condition.
