NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1.   Basis of Presentation
 
    The accounting policies followed by the Company are set forth in Note 1 of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K as of and for the year ended June 28, 2002. In the opinion of management, all adjustments necessary to fairly state the unaudited condensed consolidated financial statements have been made. All such adjustments are of a normal recurring nature. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K as of and for the year ended June 28, 2002. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year.
 
    Certain prior period amounts have been reclassified to conform to the current period presentation as a result of the adoption of Statement of Financial Accounting Standards (“SFAS”) No. 145, “Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections” (“SFAS 145”) and the termination of certain of the Company’s new business ventures.

3.   Income per Share
 
    The following table illustrates the computation of basic and diluted income per common share from continuing operations (in thousands, except per share data):

                                   
      THREE MONTHS   SIX MONTHS
      ENDED   ENDED
     
 
      DEC. 27,   DEC. 28,   DEC. 27,   DEC. 28,
      2002   2001   2002   2001
     
 
 
 
Income from continuing operations
  $ 73,040     $ 15,445     $ 95,255     $ 14,888  
 
   
     
     
     
 
Weighted average shares outstanding:

Income per share from continuing operations:
                               
 
Basic
  $ .38     $ .08     $ .49     $ .08  
 
   
     
     
     
 
 
Diluted
  $ .36     $ .08     $ .47     $ .08  
 
   
     
     
     
 

    For purposes of computing diluted income per share, antidilutive common share equivalents have been excluded from the calculation. These include employee stock options with an exercise price which exceeded the average fair market value of the common stock for the period and common shares issuable upon conversion of the 5.25% zero coupon convertible subordinated debentures due February 18, 2018 (the “Debentures”). These antidilutive common share equivalents totaled 24.2 million and 28.9 million shares for the three months ended December 27, 2002 and December 28, 2001, respectively, and 27.1 million and 30.7 million shares for the six months ended December 27, 2002 and December 28, 2001, respectively.
 
4.   Common Stock Transactions
 
    During the six months ended December 27, 2002, the Company issued approximately 841,000 shares of its common stock in connection with Employee Stock Purchase Plan (“ESPP”) purchases and approximately 1,940,000 shares of its common stock in connection with common stock option exercises, for aggregate cash proceeds of $10.0 million. During the six months ended December 28, 2001, the Company issued approximately 514,000 shares of its common stock in connection with ESPP purchases and approximately 348,000 shares of its common stock in connection with common stock option exercises, for aggregate cash proceeds of $2.6 million.
 
    During the six months ended December 27, 2002, the Company issued approximately 50,000 shares of common stock and paid $14.3 million in cash to extinguish a portion of the Debentures with a book value of $14.7 million, and an aggregate principal amount at maturity of $32.6 million. These redemptions were private, individually negotiated transactions with certain institutional investors. As of December 27, 2002, the book value of the remaining outstanding Debentures was $73.6 million and the aggregate principal amount at maturity was $160.9 million.
 
5.   Comprehensive Income
 
    Comprehensive income includes net income as well as the components of other comprehensive income (loss) which include all revenue, expense, gain and loss items that are recorded as an element of shareholders’ equity but are excluded from net income. The Company’s other comprehensive income (loss) is comprised of unrealized gains and losses on marketable securities categorized as “available for sale” under SFAS No. 115 “Accounting for Certain Investments in Debt and Equity Securities”. The components of comprehensive income for the three and six months ended December 27, 2002 and December 28, 2001 were as follows (in thousands):

                                   
      THREE MONTHS   SIX MONTHS

      DEC. 27,   DEC. 28,   DEC. 27,   DEC. 28,
      2002   2001   2002   2001
     
 
 
 
Net income
  $ 74,360     $ 12,594     $ 96,575     $ 33,112  
Other comprehensive income (loss):
                               
 
Unrealized gain (loss) on available for sale investments, net
    610       598       (709 )     (934 )
 
   
     
     
     
 
Comprehensive income
  $ 74,970     $ 13,192     $ 95,866     $ 32,178

6.   Business Segment and Discontinued Operations
 
    The Company operates in one segment, the hard drive business.
 
    During 2002, the Company terminated the operations of all new business ventures, including Connex, Inc. (“Connex”), SANavigator, Inc. (“SANavigator”), Keen Personal Media, Inc. (“Keen”) and other smaller businesses. In conjunction with these business terminations, substantially all of the operating assets of Connex were sold to Quantum Corporation in August 2001 for cash proceeds of $11.0 million, and substantially all of the operating assets of SANavigator were sold to McData Corporation in September 2001 for cash proceeds of $29.8 million. These transactions generated a one-time gain of $24.5 million, net of costs incurred from the measurement date of July 1, 2001 through the end of the period to shutdown the businesses. Accordingly, the operating results of Connex, SANavigator and Keen, and the net gain recognized on the sale of substantially all of the assets of Connex and SANavigator for the periods reported, have been segregated from continuing operations and reported separately on the unaudited condensed consolidated statements of income as discontinued operations.
 
7.   Legal Proceedings
 
    In June 1994, Papst Licensing (“Papst”) brought suit against the Company in the United States District Court for the Central District of California, alleging infringement by the Company of five disk drive motor patents owned by Papst. In December 1994, Papst dismissed its case without prejudice. In July 2002, Papst filed a new complaint against the Company and several other defendants. The suit alleges infringement by the Company of seventeen of Papst’s patents related to disk drive motors that the Company purchased from motor vendors. Papst is seeking an injunction and damages. The Company filed an answer on September 4, 2002, denying Papst’s complaint. On December 11, 2002, the lawsuit was transferred to the United States District Court for the Eastern District of Louisiana and included in the consolidated pre-trial proceedings occurring there. The lawsuit was stayed pending the outcome of certain other related litigation. The Company intends to vigorously defend the suit.
 
    On July 5, 2001, the Company’s Western Digital Technologies, Inc. subsidiary (“WDT”) and its Malaysian subsidiary (“WDM”) filed suit (the “complaint”) against Cirrus Logic, Inc. (“Cirrus”) for breach of contract and other claims resulting from Cirrus’ role as a strategic supplier of read channel chips for the Company’s hard disk drives. WDM also stopped making payments to Cirrus for past deliveries of chips and terminated all outstanding purchase orders from Cirrus for such chips. The complaint alleges that Cirrus’ unlawful conduct caused damages in excess of any amounts that may be owing on outstanding invoices or arising out of any alleged breach of the outstanding purchase orders. On August 20, 2001, Cirrus filed an answer and cross-complaint denying the allegations contained in the complaint and asserting counterclaims against the plaintiffs for, among other things, the amount of the outstanding invoices and the plaintiffs’ alleged breach of the outstanding purchase orders. The disputed payable, which is included in the Company’s balance sheet in accounts payable, is approximately $27 million. Cirrus claims that the canceled purchase orders, which are not reflected in the Company’s financial statements, total approximately $26 million. On October 9, 2001, the Court granted Cirrus’ Motion for Judgment on the Pleadings, with leave to amend, and on November 8, 2001, WDT and WDM filed their First Amended Complaint. Cirrus demurred to the First Amended Complaint, and on December 18, 2001, the Court denied Cirrus’ demurrer. On November 2, 2001, Cirrus filed Applications for Right to Attach Orders and for Writs of Attachment against WDT and WDM in the amount of $25.2 million as security for the approximately $27 million allegedly owed for read-channel chips purchased from Cirrus that is disputed by WDT and WDM. On December 20, 2001, the Court granted Cirrus’ Applications but required Cirrus to post undertakings in the amount of $514,000 on each Writ before issuance. Pursuant to agreement with Cirrus, the Company has posted a letter of credit in the amount of $25.2 million in satisfaction of the Writs of Attachment. Discovery in the case has been underway for several months and will continue until April 18, 2003. The Court has set the case for trial on May 19, 2003 and, in addition, has scheduled a mandatory settlement conference on April 25, 2003.
 
    On November 26, 2002, WDT and WDM filed a motion for summary adjudication as to Cirrus’ second and third causes of action. The parties fully briefed the motion which was scheduled to be heard on December 24, 2002. On December 24, 2002, the Court continued the summary judgment motion until February 4, 2003, and then, on February 4, 2003, further continued the motion until April 1, 2003, to allow Cirrus to conduct additional discovery. On December 3, 2002, Cirrus filed a motion for summary adjudication as to WDT and WDM’s first, second, third, fourth, fifth and seventh causes of action. The parties fully briefed the motion which was scheduled to be heard on December 31, 2002. On December 31, 2002, after hearing arguments from both sides, the Court granted Cirrus’ motion as to the first, second, fourth, fifth and seventh causes of action, and denied Cirrus’ motion as to the third cause of action. On January 30, 2003, Cirrus filed another motion for summary adjudication as to the third cause of action. The parties expect to complete briefing on the motion in the next several weeks, and the motion is currently scheduled to be heard on April 15, 2003. The Company intends to prosecute this matter and defend the cross-complaint vigorously.

    In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of monetary liability or financial impact with respect to these matters is subject to many uncertainties and is therefore not predictable with assurance, management believes that any monetary liability or financial impact to the Company from these matters, individually and in the aggregate, beyond that provided at December 27, 2002, would not be material to the Company’s financial condition. However, there can be no assurance with respect to such result and results could differ materially from those projected.
 
8.   New Accounting Pronouncements
 
    During April 2002, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 145 “Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections” (“SFAS 145”). SFAS 145 rescinds SFAS No. 4, “Reporting Gains and Losses from Extinguishment of Debt”, which required all gains and losses from the extinguishment of debt to be classified as an extraordinary item. The Company adopted SFAS 145 on June 29, 2002 at which time it began classifying gains and losses resulting from the extinguishment of debt as other income and expense, instead of extraordinary items. The adoption had no impact on the Company’s results of operations.
 
    On September 11, 2002, the Emerging Issues Task Force (“EITF”) reached a consensus on Issue No. 02-15, “Determining Whether Certain Conversions of Convertible Debt to Equity Securities are within the Scope of FASB Statement No. 84, Induced Conversions of Convertible Debt” (“SFAS 84”). The EITF deliberated this issue because of diversity in practice in the accounting for conversions of convertible debt to equity initiated by the bondholder. In practice, some registrants accounted for these transactions following SFAS 84 while others followed Accounting Principles Board Opinion No. 26, “Early Extinguishment of Debt” (“APB 26”). The EITF concluded that SFAS 84 applies to conversions of convertible debt when the offer for consideration in excess of the original conversion terms was made by the bondholder. The EITF concluded that this guidance should be followed for transactions entered into on or after September 12, 2002. Previous extinguishments of portions of the Debentures involving the issuance of common stock have been accounted for under APB 26 whereby a gain on early extinguishment was recorded equal to the excess of the net book value of the Debentures over the fair value of the consideration paid. Following the guidance in EITF Issue No. 02-15, similar early extinguishment of the Debentures or a portion of the Debentures involving common stock initiated by the bondholder will give rise to a conversion inducement expense equal to the fair value of the shares issued in excess of those required to be issued upon the exercise of the Debenture conversion feature. Due to improved cash and working capital balances, the Company does not expect to extinguish additional balances of the Debentures using its common stock. Accordingly, the Company does not expect EITF Issue No. 02-15 to have a significant impact on its future results of operations.
 
    In November 2002, FASB issued FASB Interpretation No. 45 “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others” (“FIN 45”). FIN 45 elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. FIN 45 also clarifies that a guarantor is required to recognize a liability for the fair value, or market value, of the obligation undertaken in issuing a guarantee at the inception of the guarantee. The provisions of FIN 45 relating to liability recognition does not apply to certain obligations such as product warranties and guarantees accounted for as derivatives. The initial recognition and measurement provisions apply on a prospective basis to guarantees issued or modified subsequent to December 31, 2002. The disclosure requirements of FIN 45 are effective for interim or annual financial statement periods ending after December 15, 2002. The Company adopted the provisions of FIN 45 relating to footnote disclosure of warranty obligations during this period. This information is included in Note 2 “Supplemental Financial Statement Data” of the Notes to Condensed Consolidated Financial Statements. The Company does not expect the adoption of the recognition and measurement provisions of FIN 45 will have a significant impact on its consolidated financial position or results of operations.
 
    In December 2002, FASB issued SFAS No. 148 “Accounting for Stock-Based Compensation, Transition and Disclosure” (“SFAS 148”). SFAS 148 amends the disclosure requirements of SFAS No. 123 “Accounting for Stock-Based Compensation” (“SFAS 123”) to require prominent disclosures in both interim and annual financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. SFAS 148 also amends SFAS 123 to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. The Company will commence quarterly footnote disclosure of the fair value based method of accounting for stock-based employee compensation beginning in the third quarter ending March 28, 2003. As the Company has decided not to voluntarily adopt the SFAS 123 fair value method of accounting for stock-based employee compensation, the new transition alternatives of SFAS 148 will not have a material impact on its consolidated financial position or results of operations.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     This information should be read in conjunction with the unaudited condensed interim consolidated financial statements and the notes thereto included in this Quarterly Report on Form 10-Q, and the audited consolidated financial statements and notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Western Digital Corporation’s (the “Company’s” or “Western Digital’s”) Annual Report on Form 10-K as of and for the year ended June 28, 2002.

     Unless otherwise indicated, references herein to specific years and quarters are to the Company’s fiscal years and fiscal quarters.

Forward-Looking Statements

     This report contains forward-looking statements within the meaning of the federal securities laws. The statements that are not purely historical should be considered forward-looking statements. Often they can be identified by the use of forward-looking words, such as “may,” “will,” “could,” “project,” “believe,” “anticipate,” “expect,” “estimate,” “continue,” “potential,” “plan,” “forecasts,” and the like. Statements concerning current conditions may also be forward-looking if they imply a continuation of current conditions. These statements appear in a number of places in this report and include statements regarding the intentions, plans, strategies, beliefs or current expectations of the Company with respect to, among other things:

    the financial prospects of the Company;
 
    litigation and other contingencies potentially affecting the Company’s financial position, operating results or liquidity;
 
    trends affecting the Company’s financial condition or operating results;
 
    the Company’s strategies for growth, operations, product development and commercialization; and
 
    conditions or trends in or factors affecting the computer, data storage, home entertainment or hard drive industry.

     Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. Readers are urged to carefully review the disclosures made by the Company concerning risks and other factors that may affect the Company’s business and operating results, including those made in this report under the caption “Risk Factors That May Affect Future Results” as well as the Company’s other reports filed with the Securities and Exchange Commission (the “SEC”). Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. The Company undertakes no obligation to publish revised forward-looking statements to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

Critical Accounting Policies

     The Company has prepared the accompanying unaudited condensed interim consolidated financial statements in conformity with accounting principles generally accepted in the United States for interim financial information. The preparation of the financial statements requires the use of judgment and estimates that affect the reported amounts of revenues, expenses, assets and liabilities. The Company has adopted accounting policies and practices that are generally accepted in the industry in which it operates. The Company believes the following are its most critical accounting policies that affect significant areas and involve management’s judgment and estimates. If these estimates differ significantly from actual results, the impact to the consolidated financial statements may be material.

Revenue and Accounts Receivable

     In accordance with standard industry practice, the Company has agreements with resellers that provide limited price protection for inventories held by resellers at the time of published list price reductions. In addition, the Company may have agreements with resellers that provide for stock rotation on slow-moving items and other incentive programs. In accordance with current accounting standards, the Company recognizes revenue upon shipment or delivery to resellers and records a reduction to revenue for estimated price protection and other programs in effect until the resellers sell such inventory to their customers. Adjustments are based on anticipated price decreases during the reseller holding period, estimated amounts to be reimbursed to qualifying customers as well as historical pricing information. If end-market demand for hard drives declines significantly, the Company may have to increase sell-

Table of Contents

through incentive payments to resellers, resulting in an increase in price protection allowances, which could adversely impact operating results.

     The Company establishes an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of uncollectibility based on insolvency, disputes or other collection issues. In addition, the Company routinely analyzes the different receivable aging categories and establishes reserves based on the length of time receivables are past due. If the financial condition of a significant customer deteriorates resulting in their inability to pay their accounts when due, an increase in our allowance for doubtful accounts would be required, which could negatively affect operating results.

     The Company records provisions against revenue and cost of revenue for estimated sales returns in the same period that the related revenues are recognized. The Company bases these provisions on existing product return notifications as well as historical returns by product type (see “Warranty”). If actual sales returns exceed our expectations, an increase in our sales return provisions would be required, which could negatively affect operating results.

Warranty

     The Company records an accrual for estimated warranty costs when revenue is recognized. Warranty covers cost of repair or replacement of the hard drive over the warranty period, which ranges from one to three years. The Company has comprehensive processes with which to estimate accruals for warranty, which include specific detail on hard drives in the field by product type, historical field return rates and costs to repair. If actual product return rates or costs to repair returned products increase above our expectations, we would be required to increase our warranty provision, which could negatively affect operating results.

Inventory

     Inventories are valued at the lower of cost (first-in, first-out basis) or net realizable value. Inventory write-downs are recorded for the valuation of inventory at the lower of cost or net realizable value by analyzing market conditions and estimates of future sales prices as compared to inventory costs and inventory balances.

     The Company evaluates inventory balances for excess quantities and obsolescence on a regular basis by analyzing backlog, estimated demand, inventory on hand, sales levels and other information. The Company writes down inventory balances for excess and obsolete inventory based on the analysis. Unanticipated changes in technology or customer demand could result in a decrease in demand for one or more of our products, which may require an increase in inventory write-downs, which could negatively affect operating results.

Litigation and Other Contingencies

     The Company applies Statement of Financial Accounting Standards (“SFAS”) No. 5, “Accounting for Contingencies” to determine when and how much to accrue for and disclose related to legal and other contingencies. Accordingly, the Company accrues loss contingencies when management, in consultation with its legal advisors, concludes that a loss is probable and is able to be reasonably estimated (refer to Part I, Item 1, Notes to Condensed Consolidated Financial Statements, Note 7 “Legal Proceedings” included in this Quarterly Report on Form 10-Q).

Deferred Tax Assets

     The Company’s deferred tax assets, which consist primarily of net operating loss and tax credit carryforwards, are fully reserved due to management’s determination that it is “more likely than not” that these assets will not be realized. This determination is based on the weight of available evidence, the most significant of which is the Company’s loss history in the related tax jurisdictions. Should this determination change in the future, some amount of deferred tax assets could be recognized, resulting in a tax benefit or a reduction of future tax expense.

Net Revenue

     Net revenue was $749.5 million for the three months ended December 27, 2002, an increase of 30%, or $174.8 million, from the three months ended December 28, 2001 and an increase of 29%, or $166.6 million, from the immediately preceding quarter. The increase in net revenue resulted from a normal seasonal increase in demand and selected product constraints within the industry leading to a very favorable pricing environment. Compared to the corresponding period of the prior year, the increase in net revenue was represented by a 34% increase in unit shipments, partially offset by a 3% decrease in average selling prices (“ASP’s”). The increase in net revenue as compared to the immediately preceding quarter was due to a 20% increase in unit shipments and a 7% increase in ASP’s. For the six months ended December 27, 2002, net revenue was $1,332.4 million, an increase of 31%, or $316.8 million, from the six months ended December 27, 2001. The increase in net revenue resulted from a 45% increase in unit shipments, partially offset by a 10% decrease in ASP’s.

Gross Margin

     The increase in gross margin over the corresponding three and six month periods of the prior year was primarily the result of higher unit shipments, manufacturing efficiencies and continuing cost reduction efforts. The increase in gross margin over the immediately preceding quarter was the result of higher unit shipments, higher ASP’s from an improved product mix and a favorable supply/demand environment.

Operating Expenses

     Research and development (“R&D”) expense was $34.4 million for the three months ended December 27, 2002, an increase of 17.8%, or $5.2 million, from the three months ended December 28, 2001. R&D expense for the six months ended December 27, 2002 was $66.3 million, an increase of 14.2%, or $8.3 million, from the corresponding period of the prior year. The increase in R&D expense from the corresponding periods of the prior year was primarily due to higher employee incentive payments resulting from improved operating results.

     Selling, general and administrative (“SG&A”) expense was $33.6 million for the three months ended December 27, 2002, an increase of 18.0%, or $5.1 million, from the three months ended December 28, 2001. SG&A expense for the six months ended December 27, 2002 was $60.1 million, an increase of 7.5%, or $4.2 million, from the corresponding period of the prior year. The increase in SG&A expense from the corresponding periods of the prior year was due to higher employee incentive payments resulting from improved operating results and higher retention plan expenses.

Income Tax Provision

     Income tax provision was $2.2 million and $4.0 million for the three and six months ended December 27, 2002, respectively. The increase in the income tax provision for the three and six months ended December 27, 2002 is primarily related to an increase in earnings within certain tax jurisdictions. Differences between the effective tax rate estimated for 2003 of 4%, as compared to the U.S. federal statutory rate, are primarily due to earnings of certain subsidiaries which are taxed at substantially lower tax rates as compared with U.S. statutory rates.

Discontinued Operations

     During the six months ended December 28, 2001, the Company decided to terminate the operations of Connex, Inc. (“Connex”) and SANavigator, Inc. (“SANavigator”) and sold substantially all of the assets of these two businesses for a net gain of $24.5 million. In addition, during the three months ended June 28, 2002, the Company terminated its Keen Personal Media, Inc. (“Keen”) operations. Accordingly, the operating results of Connex, SANavigator and Keen for the periods reported, and the net gain recognized on the sale of substantially all of the assets of Connex and SANavigator during the six months ended December 28, 2001, have been segregated from continuing operations and reported separately on the unaudited condensed consolidated statements of income as discontinued operations. The gain from discontinued operations for the three and six months ended December 27, 2002 primarily represents a favorable settlement of a note payable from one of the discontinued operations.

Liquidity and Capital Resources

     The Company had cash and cash equivalents of $326.9 million at December 27, 2002 and $223.7 million at June 28, 2002. Net cash provided by continuing operations was $137.5 million during the six months ended December 27, 2002 as compared to net cash provided by continuing operations of $20.5 million during the six months ended December 28, 2001. This $117.0 million improvement in cash provided by continuing operations consists of an $81.8 million improvement in the Company’s net income, net of non-cash items, and a $35.2 million decrease in cash used to fund working capital requirements. These improvements are due to significantly better operating performance by the Company, including increased revenue and gross margin, improved cost management and efficient asset management.

     The Company’s working capital requirements depend upon the effective management of its cash conversion cycle. The cash conversion cycle, which represents the sum of the number of days sales outstanding (“DSO”) and days inventory outstanding (“DIO”) less days payable outstanding (“DPO”), was negative eight days for the six months ended December 27, 2002, down from a negative nine days for the corresponding period of the prior year. The cash conversion cycle for the six months ended December 27, 2002 consists of 33 DSO, 16 DIO less 57 DPO.

     Uses of cash during the six months ended December 27, 2002 included net capital expenditures of $27.8 million, primarily to upgrade the Company’s desktop hard drive production capabilities and for the normal replacement of existing assets, $14.3 million for the extinguishment of a portion of the 5.25% zero coupon convertible subordinated debentures due February 18, 2018 (the “Debentures”) and $2.2 million for discontinued operations. Other sources of cash during the period included $10.0 million received in connection with stock option exercises and employee stock purchase plan purchases.

     The Debentures are subordinated to all senior debt; are redeemable at the option of the Company any time after February 18, 2003 at the issue price plus accrued original issue discount to the date of redemption; and at the holder’s option, will be redeemed by the Company, as of February 18, 2003, February 18, 2008 or February 18, 2013, or if there is a Fundamental Change (as defined in the Debenture documents), at the issue price plus accrued original issue discount to the date of redemption. The payment on those dates, with the exception of a Fundamental Change, can be in cash, stock or any combination, at the Company’s option. The Debentures are convertible into shares of the Company’s common stock at the rate of 14.935 shares per $1,000 principal amount at maturity. As of December 27, 2002, the remaining book value of the Debentures was $73.6 million, the aggregate principal amount at maturity was $160.9 million and the market value was $74.0 million. As outlined in a Tender Offer Statement on Schedule TO (the “Tender Offer Statement”) filed by the Company with the SEC on January 17, 2003 related to the offer by the Company to purchase the Debentures on February 18, 2003, the consideration to be paid by the Company for any Debentures surrendered for purchase and not withdrawn by that date will be solely cash. Accordingly, the Debentures have been classified as a current liability.

     The Company has a three-year senior credit facility that provides up to $125 million in revolving credit (subject to outstanding letters of credit and a borrowing base calculation), matures on September 20, 2003 and is secured by the Company’s accounts receivable, inventory, 65% of its stock in its foreign subsidiaries and other assets (the “Senior Credit Facility”). At the option of the Company, borrowings bear interest at either LIBOR (with option periods of one to three months) or a base rate, plus a margin determined by the borrowing base. The Senior Credit Facility requires the Company to maintain certain amounts of tangible net worth, prohibits the payment of cash dividends on common stock and contains a number of other covenants. As of December 27, 2002, there were no borrowings under the facility. However, the availability under the Senior Credit Facility has been reduced by $25.2 million for an outstanding letter of credit (refer to Part I, Item 1, Notes to Condensed Consolidated Financial Statements, Note 7 “Legal Proceedings” included in this Quarterly Report on Form 10-Q).

Table of Contents

     The Company believes its current cash and cash equivalents and the Senior Credit Facility will be sufficient to meet its working capital needs through the foreseeable future. There can be no assurance that the Senior Credit Facility will continue to be available to the Company. Also, the Company’s ability to sustain its working capital position is dependent upon a number of factors that are discussed below under the heading “Risk Factors That May Affect Future Results”.

Commitments

     Except as otherwise disclosed, the Company does not have any commercial commitments with terms greater than one year that would significantly impact liquidity. The following is a summary of the Company’s significant contractual cash obligations and commercial commitments at December 27, 2002:

Convertible Debentures

     The Company has Debentures due February 18, 2018. On January 17, 2003 the Company filed the Tender Offer Statement with the SEC related to the offer by the Company to purchase the Debentures validly surrendered and not withdrawn as of February 18, 2003. The Tender Offer Statement indicated the consideration to be paid by the Company for the Debentures validly surrendered and not withdrawn by February 18, 2003 will be solely cash of $459.64 per $1,000 principal amount at maturity. For a description of the Debentures, see the discussion under “Liquidity and Capital Resources”.

Operating Leases

     The Company leases certain facilities and equipment under long-term, non-cancelable operating leases which expire at various dates through 2012. The following table summarizes the future payments of these leases (in thousands):

Purchase Orders

     In the normal course of business, to reduce the risk of component shortages, the Company enters into purchase commitments with suppliers for the purchase of hard drive components used to manufacture the Company’s products. These commitments generally cover forecasted component supplies needed for production during the next quarter, become payable upon receipt of the components and may be non-cancelable (cancellation charges may be significant). The Company’s relationship with suppliers allows for some flexibility within these commitments and quantities are subject to change as a quarter progresses and the Company’s needs change.

Forward Exchange Contracts

     Although the majority of the Company’s transactions are in U.S. Dollars, some transactions are based in various foreign currencies. The Company purchases short-term, forward exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for operating expenses denominated in foreign currencies. The Company does not purchase short-term forward exchange contracts for trading purposes. As of December 27, 2002, the Company had $9.0 million outstanding of purchased foreign currency forward exchange contracts. The contract maturity dates do not exceed three months. At December 27, 2002, the carrying value of the contracts approximated fair value.

Risk Factors That May Affect Future Results

Risk factors related to the hard drive industry in which we operate

Our operating results depend on our being among the first-to-market and first-to-volume with our new products at a low cost.

     To achieve consistent success with computer manufacturer customers, we must be an early provider of next generation hard drives featuring leading technology and high quality. If we fail to:

    develop new products with features required by our customers,
 
    consistently maintain or improve our time-to-market performance with our new products,
 
    produce these products in sufficient volume within our rapid product cycle,
 
    qualify these products with key customers on a timely basis by meeting our customers’ performance and quality specifications,
 
    achieve acceptable manufacturing yields and costs with these products, or
 
    consistently meet stated quality requirements on delivered products,

our operating results could be adversely affected.

Product life cycles require continuous technical innovation associated with higher areal densities.

     New products require higher areal densities (the gigabyte of storage per disk) than previous product generations, posing formidable technical challenges. Higher areal densities require fewer heads and disks to achieve a given drive capacity, which means that existing head technology must be improved or new technology developed to accommodate more data on a single disk. Our failure to bring these new products to market on time and at acceptable costs could put us at a competitive disadvantage to companies that achieve these results.

Increases in areal density may outpace customers’ demand for storage capacity.

     The rate of increase in areal density may be greater than the increase in our customers’ demand for aggregate storage capacity. This could lead to our customers’ storage capacity needs being satisfied with fewer hard disk drives, thereby decreasing our sales. As a result, even with increasing aggregate demand for storage capacity, our unit volumes could decline, which could adversely affect our results of operations.

Short product life cycles make it difficult to recover the cost of development.

     Product life cycles have extended during the past twelve months due to a decrease in the rate of hard drive areal density growth. However, there can be no assurance that this trend will continue. Historically, more rapid increases in areal density resulted in shorter product life cycles, with each generation of hard drives being more cost effective than the previous one. Shorter product life cycles make it more difficult to recover the cost of product development before the product becomes obsolete. Although we believe that the current rate of growth in areal density is lower than in the past several years and will continue to decrease in the near term, we expect that areal density will continue to increase. Our failure to recover the cost of product development in the future could adversely affect our operating results.

Short product life cycles and new products force us to continually qualify new products with our customers.

     Short product life cycles and continuously changing products require us to regularly engage in new product qualification with our customers. To be considered for qualification we must be among the leaders in time-to-market with our new products. Once a product is accepted for qualification testing, any failure or delay in the qualification process can result in our losing sales to that customer until the next generation of products is introduced. The effect of missing a product qualification opportunity is magnified by the limited number of high volume computer manufacturers, most of which continue to consolidate their share of the personal computer (“PC”) market. If product life cycles continue to be extended due to a decrease in the rate of areal density growth, we may have a significantly longer period to wait before we have an opportunity to qualify a new product with a customer, which could harm our competitive position. These risks are increased because we expect cost improvements and competitive pressures to result in declining sales and gross margins on our current generation products.

Increasing product life cycles may require us to reduce our costs to remain competitive.

     Longer product life cycles have resulted from a decrease in the rate of areal density growth in the past twelve months. If longer product life cycles continue, we may need to develop new technologies or programs to reduce our costs on any particular product in order to maintain competitive pricing for such product. This may result in an increase in our overall expenses and a decrease in our gross margins, both of which could adversely affect our operating results.

Unexpected technology advances in the hard drive industry could harm our competitive position.

     If one of our competitors were able to implement a significant advance in head or disk drive technology that enables a “step-change” increase in areal density that permits greater storage of data on a disk, it could put us at a competitive disadvantage and harm our operating results.

     Advances in magnetic, optical, semiconductor or other data storage technologies could result in competitive products that have better performance or lower cost per unit of capacity than our products. If these products prove to be superior in performance or cost per unit of capacity, we could be at a competitive disadvantage to the companies offering those products.

The decline of ASP’s in the hard disk drive industry could adversely affect our operating results.

     The hard disk drive industry has experienced declining ASP’s in recent years. Although the rate of decline has decreased in recent quarters, there can be no assurance that this trend will continue. Increases in areal density mean that the average drive we sell has fewer heads and disks, and therefore lower component cost. Because of the competitiveness of the hard drive industry, lower costs generally mean lower prices. This is true even for those products that are competitive and introduced into the market in a timely manner. Our ASP’s decline even further when competitors lower prices as a result of decreased costs or to absorb excess capacity, liquidate excess inventories, restructure or attempt to gain market share. A continued decline in ASP’s could cause our operating results to suffer.

The hard drive industry is highly competitive and characterized by rapid shifts in market share among the major competitors.

     The price of hard drives has fallen over time due to increases in supply, cost reductions, technological advances and price reductions by competitors seeking to liquidate excess inventories or attempting to gain market share. In addition, rapid technological changes often reduce the volume and profitability of sales of existing products and increase the risk of inventory obsolescence. These factors, taken together, result in significant and rapid shifts in market share among the industry’s major participants. For example, during the first quarter of 2000, the Company lost market share as a result of a product recall. Similar losses in market share could adversely affect our operating results.

Our prices and margins are subject to declines due to unpredictable end-user demand and periodic oversupply of hard drives.

     Demand for our hard drives depends on the demand for systems manufactured by our customers and on storage upgrades to existing systems. The demand for systems has been volatile in the past and often has had an exaggerated effect on the demand for hard drives in any given period. As a result, the hard drive market tends to experience periods of excess capacity, which typically lead to intense price competition. During calendar year 2001 and the first half of calendar year 2002, the industry experienced weak PC demand in the U.S. and other markets due in part to general economic conditions worldwide. If intense price competition occurs as a

16


Table of Contents

result of weak demand, we may be forced to lower prices sooner and more than expected, which could result in lower revenues and gross margins.

Changes in the markets for hard drives require us to develop new products.

     Over the past few years the consumer market for desktop computers has shifted significantly towards lower priced systems. According to data released by International Data Corporation Tracker in December 2002, systems priced below $599 currently comprise the fastest growing segment of the consumer market for desktop computers. Although we were late to market with a value line hard drive to serve the low-cost PC market, we are now offering such value line products at prices that we view as competitive. However, if we are not able to continue to offer a competitively priced value line hard drive for the low-cost PC market, our share of that market will likely fall, which could harm our operating results.

     The PC market is fragmenting into a variety of computing devices and products. Some of these products, such as Internet appliances, may not contain a hard drive. On the other hand, many industry analysts expect, as do we, that as broadcasting and communications are increasingly converted to digital technology from the older, analog technology, the technology of computers, consumer electronics and communication devices will converge, and hard drives will be found in many consumer products other than computers. For the quarter ended December 27, 2002, approximately 7% of our unit sales were for consumer products other than computers, primarily gaming devices. If we are not successful in using our hard drive technology and expertise to develop new products for these emerging markets, it will likely harm our operating results.

The market acceptance for hard disk drives in game consoles continues to be uncertain.

     The use of hard disk drives in the game console market is a fairly recent trend. Due to the price competitive nature of the hard disk drive industry, with selling prices of PC’s being substantially higher than game consoles, game manufacturers may not have the ability to either incorporate or continue to incorporate hard disk drives into their overall architecture. In addition, current price reduction demands from either current or future game console customers may not make hard disk drive integration an attractive market for us or other hard drive manufacturers.

If we do not successfully expand into new hard drive market segments, our business may suffer.

     To remain a significant supplier of hard disk drives, we will need to offer a broad range of disk drive products to our customers. We currently offer a variety of 3.5-inch form factor hard disk drives for the desktop computer market. However, demand for desktop hard drives may shift to products in smaller form factors, which we do not currently offer, but which some of our competitors offer. While we continually develop new products, the success of our new product introductions is dependent on a number of factors, including difficulties faced in manufacturing ramp, market acceptance, effective management of inventory levels in line with anticipated product demand, and the risk that our new products will have quality problems or other defects in the early stages of introduction that were not anticipated in the design of those products. If we fail to successfully develop and manufacture new products, customers may decrease the amounts of our products that they purchase, and we may lose business to our competitors who offer these products or who use their dominance in the enterprise or mobile market to encourage sales of desktop hard drives.

We depend on our key personnel and skilled employees.

     Our success depends upon the continued contributions of our key personnel and skilled employees, many of whom would be extremely difficult to replace. Worldwide competition for skilled employees in the hard drive industry is intense. Volatility or lack of positive performance in our stock price may adversely affect our ability to retain key personnel or skilled employees who have been granted stock options. If we are unable to retain our existing key personnel or skilled employees or hire and integrate new key personnel or skilled employees, our operating results would likely be harmed.

Risk factors relating to Western Digital particularly

Loss of market share with a key customer could harm our operating results.

     A majority of our revenue comes from a few customers. For example, during 2002, sales to our top 10 customers accounted for approximately 58% of revenue. These customers have a variety of suppliers to choose from and therefore can make substantial demands on us. Even if we successfully qualify a product with a customer, the customer generally is not obligated to purchase any minimum volume of products from us and is able to terminate its relationship with us at any time. Our ability to maintain strong

17


Table of Contents

relationships with our principal customers is essential to our future performance. If we lose a key customer, or if any of our key customers reduce their orders of our products or require us to reduce our prices before we are able to reduce costs, our operating results would likely be harmed. For example, this occurred with our enterprise hard drive product line early in the third quarter of 2000 and is one of the factors which led to our decision to exit the enterprise hard drive market.

Dependence on a limited number of qualified suppliers of components could lead to delays, lost revenue or increased costs.

     Because we do not manufacture any of the basic components in our hard drives, an extended shortage of required components or the failure of key suppliers to remain in business, adjust to market conditions, or to meet our quality, yield or production requirements could harm us more severely than our competitors, some of whom manufacture certain of the components for their hard drives, and could significantly harm our operating results. A number of the components used by us are available from only a single or limited number of qualified outside suppliers. If a component is in short supply, or a supplier fails to qualify or has a quality issue with a component, we may experience delays or increased costs in obtaining that component. In addition, if a component becomes unavailable, we could suffer significant loss of revenue. For example, we lost revenue in September 1999 when we had to shut down our Caviar product line production for approximately two weeks as a result of a faulty power driver chip that was sole-sourced from a third party supplier.

     To reduce the risk of component shortages, we attempt to provide significant lead times when buying these components. As a result, we may have to pay significant cancellation charges to suppliers if we cancel orders, as we did in 1998 when we accelerated our transition to magnetoresistive recording head technology, and as we did in 2000 as a result of our decision to exit the enterprise hard drive market.

     In April 1999, we entered into a three-year volume purchase agreement with Komag under which we buy a substantial portion of our media components from Komag. In October 2001, we amended the Komag volume purchase agreement to extend the initial term to six years. Similarly, in February 2001, we entered into a two-year volume purchase agreement with IBM under which we buy a substantial portion of our read channel chips from IBM. Effective June 2002, we amended the IBM volume purchase agreement to extend the initial term through December 31, 2003. These strategic relationships have increased our dependence on each of Komag and IBM as a supplier. Our future operating results may depend substantially on Komag’s ability to timely qualify its media components in our new development programs, and each of Komag’s and IBM’s ability to supply us with these components or chips, as the case may be, in sufficient volume to meet our production requirements. A significant disruption in Komag’s ability to manufacture and supply us with media components or IBM’s ability to manufacture and supply us with read channel chips could harm our operating results.

To develop new products we must maintain effective partner relationships with our strategic component suppliers.

     Under our business model, we do not manufacture any of the component parts used in our hard drives. As a result, the success of our products depends on our ability to gain access to and integrate parts that are “best in class” from reliable component suppliers. To do so we must effectively manage our relationships with our strategic component suppliers. We must also effectively integrate different products from a variety of suppliers, each of which employs variations on technology which can impact, for example, feasible combinations of heads and media components. We are currently engaged in litigation with Cirrus, a supplier who previously was the sole source of read channel chips for our hard drives. As a result of the disputes that gave rise to the litigation, our business operations were at risk until another supplier’s read channel chips could be designed into our products. Similar disputes with other strategic component suppliers could adversely affect our operating results.

We have only one primary high-volume manufacturing facility, and a secondary smaller facility, which subjects us to the risk of damage or loss of either facility.

     The majority of our manufacturing volume comes from one facility in Malaysia. During 2002, we acquired a second, smaller manufacturing facility in Thailand. A fire, flood, earthquake or other disaster, condition or event that adversely affects either our Malaysia or Thailand facility or ability to manufacture could result in a loss of sales and revenue and harm our operating results.

Terrorist attacks may adversely affect our business and operating results.

     The terrorist attacks on the United States on September 11, 2001, the United States-led military response to counter terrorism and the continued threat of terrorist activity and other acts of war or hostility have created uncertainty in the financial and insurance markets and have significantly increased the political, economic and social instability in some of the geographic areas in which the

18


Table of Contents

Company operates. Further acts of terrorism, either domestically or abroad, could create further uncertainties and instability. To the extent this results in disruption or delays of our manufacturing capabilities or shipments of our products, our business, operating results and financial condition could be adversely affected.

Manufacturing our products abroad subjects us to numerous risks.

     We are subject to risks associated with our foreign manufacturing operations, including:

    obtaining requisite United States and foreign governmental permits and approvals;
 
    currency exchange rate fluctuations or restrictions;
 
    political instability and civil unrest;
 
    transportation delays or higher freight rates;
 
    labor problems;
 
    trade restrictions or higher tariffs;
 
    exchange, currency and tax controls and reallocations;
 
    increasing labor and overhead costs; and
 
    loss or non-renewal of favorable tax treatment under agreements or treaties with foreign tax authorities.

     We have attempted to manage the impact of foreign currency exchange rate changes by, among other things, entering into short-term, forward exchange contracts. However, those contracts do not cover our full exposure and can be canceled by the issuer if currency controls are put in place, which occurred in Malaysia during the first quarter of 1999. As a result of the Malaysian currency controls, we are no longer hedging the Malaysian currency risk. Currently, we hedge the Thai Baht and British Pound Sterling.

The nature of our business and our reliance on intellectual property and other proprietary information subjects us to the risk of significant litigation.

     The hard drive industry has been characterized by significant litigation. This includes litigation relating to patent and other intellectual property rights, product liability claims and other types of litigation. Litigation can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of litigation are inherently uncertain and may result in adverse rulings or decisions. We may enter into settlements or be subject to judgments that may, individually or in the aggregate, have a material adverse effect on our business, financial condition or results of operations.

     We are currently evaluating notices of alleged patent infringement or notices of patents from patent holders. We also are a party to several judicial and other proceedings relating to patent and other intellectual property rights. If claims or actions are asserted against us, we may be required to obtain a license or cross-license, modify our existing technology or design a new non-infringing technology. Such licenses or design modifications can be extremely costly. In addition, no assurance can be given that in a particular case a license will be offered or that the offered terms will be acceptable to us. We may also be liable for any past infringement. If there is an adverse ruling against us in an infringement lawsuit, an injunction could be issued barring production or sale of any infringing product. It could also result in a damage award equal to a reasonable royalty or lost profits or, if there is a finding of willful infringement, treble damages. Any of these results would likely increase our costs and harm our operating results.

Our reliance on intellectual property and other proprietary information subjects us to the risk that these key ingredients of our business could be copied by competitors.

     Our success depends, in significant part, on the proprietary nature of our technology, including non-patentable intellectual property such as our process technology. Despite safeguards, to the extent that a competitor is able to reproduce or otherwise capitalize on our technology, it may be difficult, expensive or impossible for us to obtain necessary legal protection. Also, the laws of some foreign countries may not protect our intellectual property to the same extent as do the laws of the United States. In addition to patent protection of intellectual property rights, we consider elements of our product designs and processes to be proprietary and confidential. We rely upon employee, consultant and vendor non-disclosure agreements and contractual provisions and a system of internal safeguards to protect our proprietary information. However, any of our registered or unregistered intellectual property rights may be challenged or exploited by others in the industry, which might harm our operating results.

We are subject to risks related to product defects, which could subject us to warranty claims in excess of our warranty provisions or which are greater than anticipated due to the unenforceability of liability limitations.

     We generally warrant our products for one to three years. The standard warranties used by us contain limits on damages and exclusions of liability for consequential damages and for negligent or improper use of the products. We generally record an accrual for estimated warranty costs at the time revenue is recognized. We may incur additional operating expenses if our warranty provision does not reflect the actual cost of resolving issues related to defects in our products. If these additional expenses are significant, it could adversely affect our business, financial condition and results of operations.

Inaccurate projections of demand for our product can cause large fluctuations in our quarterly results.

     We typically book and ship a high percentage (at times in excess of 50%) of our total quarterly sales in the third month of the quarter, which makes it difficult for us to forecast our financial results prior to the end of the quarter. In addition, our quarterly projections and results may be subject to significant fluctuations as a result of a number of other factors including:

    the timing of orders from and shipment of products to major customers;
 
    our product mix;
 
    changes in the prices of our products;
 
    manufacturing delays or interruptions;
 
    acceptance by customers of competing products in lieu of our products;
 
    variations in the cost of components for our products;
 
    limited access to components that we obtain from a single or a limited number of suppliers, such as Komag and IBM;
 
    competition and consolidation in the data storage industry; and
 
    seasonal and other fluctuations in demand for PC’s often due to technological advances.

     If we do not forecast total quarterly demand accurately, it can have a material adverse effect on our quarterly results.

Rapidly changing market conditions in the hard drive industry make it difficult to estimate actual results.

     We have made and continue to make a number of estimates and assumptions relating to our consolidated financial reporting. The rapidly changing market conditions with which we deal means that actual results may differ significantly from our estimates and assumptions. Key estimates and assumptions for us include:

    accruals for warranty costs related to product defects;
 
    price protection adjustments and other sales promotions and allowances on products sold to retailers, resellers and distributors;
 
    inventory adjustments for write-down of inventories to lower of cost or market value (net realizable value);
 
    reserves for doubtful accounts;
 
    accruals for product returns;
 
    accruals for litigation and other contingencies; and
 
    reserves for deferred tax assets.

The market price of our common stock is volatile.

     The market price of our common stock has been, and may continue to be, extremely volatile. Factors such as the following may significantly affect the market price of our common stock:

    actual or anticipated fluctuations in our operating results;
 
    announcements of technological innovations by us or our competitors which may decrease the volume and profitability of sales of our existing products and increase the risk of inventory obsolescence;
 
    new products introduced by us or our competitors;
 
    periods of severe pricing pressures due to oversupply or price erosion resulting from competitive pressures;
 
    developments with respect to patents or proprietary rights;
 
    conditions and trends in the hard drive, data and content management, storage and communication industries; and
 
    changes in financial estimates by securities analysts relating specifically to us or the hard drive industry in general.

     In addition, general economic conditions may cause the stock market to experience extreme price and volume fluctuations from time to time that particularly affect the stock prices of many high technology companies. These fluctuations often appear to be unrelated to the operating performance of the companies.

     Securities class action lawsuits are often brought against companies after periods of volatility in the market price of their securities. A number of such suits have been filed against us in the past, and should any new lawsuits be filed, such matters could result in substantial costs and a diversion of resources and management’s attention.

We may be unable to raise future capital through debt or equity financing.

     Due to the risks described herein, in the future we may be unable to maintain adequate financial resources for capital expenditures, expansion or acquisition activity, working capital and research and development. We have a credit facility, which matures on September 20, 2003. If we decide to increase or accelerate our capital expenditures or research and development efforts, or if results of operations do not meet our expectations, we could require additional debt or equity financing. However, we cannot ensure that additional financing will be available to us or available on acceptable terms. An equity financing could also be dilutive to our existing stockholders.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Disclosure About Foreign Currency Risk

     Although the majority of the Company’s transactions are in U.S. Dollars, some transactions are based in various foreign currencies. The Company purchases short-term, forward exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for operating expenses denominated in foreign currencies. The purpose for entering into these hedge transactions is to minimize the impact of foreign currency fluctuations on the results of operations. A majority of the increases or decreases in the Company’s foreign currency operating expenses are offset by gains and losses on the hedges. The contract maturity dates do not exceed three months. The Company does not purchase short-term forward exchange contracts for trading purposes. Currently, the Company focuses on hedging its foreign currency risk related to the British Pound Sterling and the Thai Baht.

21


Table of Contents

     As of December 27, 2002, the Company had outstanding the following purchased foreign currency forward exchange contracts (in millions, except weighted average contract rate):

                   
      U.S. DOLLAR   WEIGHTED
      EQUIVALENT   AVERAGE
      AMOUNT   CONTRACT RATE
     
 
FOREIGN CURRENCY FORWARD CONTRACTS:
               
 
British Pound Sterling
  $ 3.6       1.59  
 
Thai Baht
  $ 5.4       43.03  

     During the three and six months ended December 27, 2002 and December 28, 2001, respectively, total realized transaction and forward exchange contract currency gains and losses were not material to the condensed consolidated financial statements. Based on historical experience, the Company does not expect that a significant change in foreign exchange rates would materially affect the Company’s condensed consolidated financial statements.

Disclosure About Other Market Risks

Fixed Interest Rate Risk

     At December 27, 2002, the market value of the Debentures was approximately $74.0 million, compared to the related book value of $73.6 million. At the option of the holder, the Debentures will be repurchased by the Company, as of February 18, 2003, February 18, 2008, or February 18, 2013, or if there is a Fundamental Change (as defined in the Debenture documents), at the issue price plus accrued original issue discount to the date of redemption. The payment on those dates, with the exception of a Fundamental Change, can be in cash, stock or any combination, at the Company’s option.

Variable Interest Rate Risk

     At the option of the Company, borrowings under the Senior Credit Facility would bear interest at either LIBOR (with option periods of one to three months) or a base rate, plus a margin determined by the borrowing base. This is the only Company borrowing facility which does not have a fixed rate of interest. At December 27, 2002, there were no borrowings outstanding under the Senior Credit Facility.

Fair Value Risk

     The Company owns approximately 1.0 million shares of Vixel Corporation common stock (the “Vixel Stock”). As of December 27, 2002, the market value of the Vixel Stock was approximately $1.8 million. Changes in the market value of the Vixel Stock are recorded as unrealized gains or losses in other comprehensive income (shareholders’ equity). As of December 27, 2002, a $1.8 million total accumulated unrealized gain has been recorded in accumulated other comprehensive income related to the Vixel Stock. If the Company sells any portion of the Vixel Stock, the related unrealized gain on the date of sale will become realized and reflected as a gain in the Company’s statement of income. As a result of market conditions, the market value of the Vixel Stock had increased from approximately $1.8 million as of December 27, 2002 to approximately $2.4 million as of January 24, 2003. Due to market fluctuations, a decline in the Vixel Stock’s fair market value could occur in future periods.

Item 4. CONTROLS AND PROCEDURES

(a)   Within the 90-day period prior to the filing of this report, an evaluation was carried out under the supervision and with the participation of our Chief Executive Officer and our Chief Financial Officer of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rule 13a-14(c) under the Securities Exchange Act of 1934, as amended. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these disclosure controls and procedures are effective.
 
(b)   There have been no significant changes in our internal controls or in other factors that could significantly affect the internal controls subsequent to the date of our most recent evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses.
