NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Summary of Significant Accounting Policies

Organization

These interim condensed consolidated financial statements are unaudited but reflect, in the opinion of management, all adjustments, consisting of normal recurring adjustments and accruals, necessary to present fairly the financial position of SanDisk Corporation and its subsidiaries (the “Company”) as of April 1, 2007, the statements of operations for the three months ended April 1, 2007 and April 2, 2006 and the statements of cash flows for the three months ended April 1, 2007 and April 2, 2006. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), have been omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s most recent Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current period presentation. The results of operations for the three months ended April 1, 2007 are not necessarily indicative of the results to be expected for the entire fiscal year.

The Company’s fiscal year ends on the Sunday closest to December 31, and its fiscal quarters end on the Sunday closest to March 31, June 30, and September 30, respectively. The first quarters of fiscal 2007 and fiscal 2006 ended on April 1, 2007 and April 2, 2006, respectively. Fiscal 2007 ends on December 30, 2007 and fiscal 2006 ended on December 31, 2006.

Organization and Nature of Operations. The Company was incorporated in Delaware on June 1, 1988. The Company designs, develops and markets flash storage card products used in a wide variety of consumer electronics products. The Company operates in one segment, flash memory storage products.

Principles of Consolidation. The condensed consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Minority interest represents the minority shareholders’ proportionate share of the net assets and results of operations of our majority-owned subsidiary. The condensed consolidated financial statements also include the results of companies acquired by the Company from the date of each acquisition.

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, product returns, bad debts, inventories and related reserves, investments, income taxes, warranty obligations, restructuring and contingencies, stock compensation and litigation. The Company bases estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates.

Recent Accounting Pronouncements

SFAS No. 159. In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 159 (“SFAS 159”), Establishing the Fair Value Option for Financial Assets and Liabilities. The FASB has issued SFAS 159 to permit all entities to choose to elect, at specified election dates, to measure eligible financial instruments at fair value. An entity shall report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date, and recognize upfront costs and fees related to those items in earnings as incurred and not deferred. SFAS 159 applies to fiscal years beginning after November 15, 2007, or the Company’s 2008 fiscal year, with early adoption permitted for an entity that has also elected to apply the provisions of SFAS No. 157, Fair Value Measurements. An entity is prohibited from retrospectively applying SFAS 159, unless it chooses early adoption. SFAS 159 also applies to eligible items existing at November 15, 2007 (or early adoption date). The Company has not completed its analysis but does not expect the adoption of SFAS 159 to have a material effect on the Company’s financial condition.

EITF Issue No. 07-2. In the Emerging Issues Task Force (“Task Force”) March 15, 2007 meeting, the Task Force opened EITF Issue No. 07-2 (“EITF 07-2”), Accounting for Convertible Debt Instruments That Require or Permit Partial Cash

3. Share-Based Compensation

Share-Based Plans

The Company has a share-based compensation program that provides its Board of Directors with broad discretion in creating equity incentives for employees, officers, non-employee board members and non-employees. This program includes incentive and non-statutory stock option awards, stock appreciation rights awards, restricted stock awards, performance-based cash bonus awards for Section 16 executive officers and an automatic grant program for non-employee board members pursuant to which such individuals will receive option grants or other stock awards at designated intervals over their period of board service. These awards are granted under various plans, all of which are stockholder approved. Grants and awards under the discretionary grant program generally vest as follows: 25% of the shares vest on the first anniversary of the vesting commencement date and the remaining 75% vest proportionately each quarter over the next 12 quarters of continued service. Awards under the stock issuance program generally vest in equal annual installments over a 4 year period. Grants under the automatic grant program vest in accordance with the specific vesting provisions set forth in that program. Additionally, we have an Employee Stock Purchase Plan (“ESPP”) that allows employees to purchase shares of common stock at 85% of the fair market value at the date of purchase.

Valuation Assumptions

The fair value of the Company’s stock options granted to employees for the three months ended April 1, 2007 and April 2, 2006 was estimated using the following weighted average assumptions:


	Three months ended
	April 1, 2007			April 2, 2006

Dividend yield	None			None
Expected volatility		0.46			0.51
Risk-free interest rate		4.55	%		4.39	%
Expected lives	3.5 years			3.6 years
Estimated annual forfeitures rate		7.74	%		8.20	%
Weighted average fair value at grant date	$	15.64		$	27.17

Employee Stock Purchase Plan Shares
Dividend yield	None			None
Expected volatility		0.44			0.54
Risk-free interest rate		5.16	%		4.69	%

Share-Based Compensation Plan Activities

Stock Option and SARs. Stock option and SAR activity for the three months ended April 1, 2007, is as follows (in thousands, except exercise price and contractual term):


						Weighted
						Average
				Weighted		Remaining
				Average		Contractual		Aggregate
	Shares			Exercise Price		Term (Years)		Intrinsic Value
Options and SARs outstanding at December 31, 2006		26,392		$	31.97
Granted		3,952			42.02
Exercised		(1,671	)		21.13
Forfeited		(457	)		45.21
Expired		(44	)		55.92

Options and SARs outstanding at April 1, 2007		28,172			33.78		6.5	$	372,452

Options and SARs vested and expected to vest after April 1, 2007		26,312			33.00		6.4	$	365,847

Options and SARs exercisable at April 1, 2007		12,239		$	21.85		5.7	$	287,838

During the three months ended April 1, 2007 and April 2, 2006, the aggregate intrinsic value of options and SARs exercised under the Company’s share-based compensation plans was $32.0 million and $117.7 million, respectively. At April 1, 2007, the total compensation cost related to options granted to employees under the Company’s share-based compensation plans but not yet recognized was approximately $252.1 million, net of estimated forfeitures. The unamortized compensation expense will be amortized on a straight-line basis, and the weighted average period of this expense is approximately 2.7 years.

Restricted Stock and Restricted Stock Units. Restricted stock and restricted stock units are converted into shares of the Company’s common stock upon vesting on a one-for-one basis. Typically, vesting of restricted stock is subject to the employee’s continuing service to the Company. The cost of these awards is determined using the fair value of the Company’s common stock on the date of the grant, and compensation is recognized on a straight-line basis over the requisite vesting period.

A summary of the changes in restricted stock units outstanding under the Company’s share-based compensation plan during the three months ended April 1, 2007, is presented below (in thousands, except for grant date fair value):


				Weighted Average
				Grant Date Fair		Aggregate
	Shares			Value		Intrinsic Value
Non-vested share units at December 31, 2006		598		$	58.71
Granted		86			41.21
Vested		(119	)		61.47
Forfeited		(29	)		68.90

Non-vested share units at April 1, 2007		536		$	54.73	$	23,457

As of April 1, 2007, the Company had $28.0 million of total unrecognized compensation expense, net of estimated forfeitures, related to restricted stock. The unamortized compensation expense will be recognized on a straight-line basis, and the weighted average estimated remaining life is 2.9 years.

Employee Stock Purchase Plans. At April 1, 2007, there was $1.6 million of total unrecognized compensation cost related to the ESPP that is expected to be recognized over a period of approximately 4 months.

4. Restructuring

During the first quarter of fiscal 2007, the Company implemented a restructuring plan which included reductions in workforce in all functions of the organization worldwide and closures of redundant facilities in order to reduce the Company’s cost structure. A restructuring charge of $6.5 million was recorded, of which $5.9 million related to severance and benefits to 149 terminated employees. All expenses, including adjustments, associated with the Company’s restructuring plans are included in “Restructuring” in the Condensed Consolidated Statements of Operations.

The following table sets forth an analysis of the components of the restructuring charge and the provision adjustment and payments made against the reserve through April 1, 2007 (in thousands):


				Lease
				Obligations
	Severance			and Other
	And Benefits			Charges		Total
Restructuring provision	$	5,947		$	569	$	6,516
Cash paid		(969	)		—		(969	)

Reserve balance at April 1, 2007	$	4,978		$	569	$	5,547

The Company anticipates that approximately $5.0 million of the remaining restructuring reserve balance will be paid out in cash in the second quarter of fiscal 2007 with the remaining balance payable through the first quarter of fiscal 2010.

9. Share Repurchase Program

During the fourth quarter of fiscal 2006, the Company’s Board of Directors authorized the repurchase of up to $300 million of the Company’s common stock in the open market over two years following the date of authorization. Share repurchases have been and will be made from time-to-time in the open market at the Company’s discretion within the authorized program. The stock repurchase program does not obligate the Company to repurchase any particular amount of shares and may be suspended at the Company’s discretion. During the first quarter ended April 1, 2007, the Company repurchased 190,184 shares, for an aggregate purchase price of approximately $7.1 million on the open market, all of which are held as treasury stock and accounted for using the cost method. In addition, during the first quarter of fiscal 2007, the Company entered into a $35 million prepaid forward variable share repurchase agreement with a third-party investment bank to deliver shares by May 7, 2007, and has recorded this amount as a prepaid stock repurchase under stockholders’ equity. The Company entered into this agreement in order to enable it to repurchase shares at a guaranteed discount of the Volume Weighted Average Price (“VWAP”) of its common shares over the period. The Company only enters into such transactions when the discount that it receives is higher than the foregone return on its cash prepayment to the financial institution. The Company did not pay any explicit commissions or fees on this prepaid forward repurchase agreement.

10. Commitments, Contingencies and Guarantees

FlashVision. The Company has a 49.9% ownership interest in FlashVision Ltd. (“FlashVision”), a business venture with Toshiba Corporation (“Toshiba”), formed in fiscal 2000. In the venture, the Company and Toshiba have collaborated in the development and manufacture of NAND flash memory products. These NAND flash memory products are manufactured by Toshiba at its 200-millimeter wafer fabrication facilities, located in Yokkaichi, Japan, using the semiconductor manufacturing equipment owned or leased by FlashVision. FlashVision purchases wafers from Toshiba at cost and then resells those wafers to the Company and Toshiba at cost plus a markup. Toshiba owns 50.1% of this venture. The Company accounts for its 49.9% ownership position in FlashVision under the equity method of accounting. The terms of the FlashVision venture contractually obligate the Company to purchase its provided three month forecast for FlashVision’s NAND wafer supply, which generally equals 50 percent of the venture’s output. The Company cannot estimate the total amount of this commitment as of April 1, 2007, because it is based upon future costs and volumes. In addition, the Company is committed to fund 49.9% of FlashVision’s costs to the extent that FlashVision’s revenues from wafer sales to the Company and Toshiba are insufficient to cover these costs.

As of April 1, 2007, the Company had notes receivable from FlashVision of 1.5 billion Japanese yen, or approximately $13 million based upon the exchange rate at April 1, 2007. These notes are secured by the equipment purchased by FlashVision using the note proceeds. Since fiscal 2006, the Company has been receiving cash repayments against the note receivable and expects FlashVision to continue generating cash to pay down this note receivable over time. The Company agreed to indemnify Toshiba for certain liabilities Toshiba incurs as a result of Toshiba’s guarantee of the FlashVision equipment lease arrangement. If FlashVision fails to meet its lease commitments, and Toshiba fulfills these commitments under the terms of Toshiba’s guarantee, then the Company will be obligated to reimburse Toshiba for 49.9% of any claims and associated expenses under the lease, unless the claims result from Toshiba’s failure to meet its obligations to FlashVision or its covenants to the lenders. Because FlashVision’s equipment lease arrangement is denominated in Japanese yen, the maximum amount of the Company’s contingent indemnification obligation on a given date when converted to U.S. dollars will fluctuate based on the exchange rate in effect on that date. See “Off Balance Sheet Liabilities.”

Flash Partners. The Company has a 49.9% ownership interest in Flash Partners Ltd. (“Flash Partners”), a business venture with Toshiba, formed in fiscal 2004.

Flash Partners purchases wafers from Toshiba at cost and then resells those wafers to the Company and Toshiba at cost plus a markup. Toshiba owns 50.1% of this venture. The Company accounts for its 49.9% ownership position in Flash Partners under the equity method of accounting. The Company is committed to purchase its provided three month forecast for Flash Partner’s NAND wafer supply, which generally equals 50 percent of the venture’s output. The Company cannot estimate the total amount of this commitment as of April 1, 2007, because it is based upon future costs and volumes. In addition, the Company is committed to fund 49.9% of Flash Partners’ costs to the extent that Flash Partners’ revenues from wafer sales to the Company and Toshiba are insufficient to cover these costs.

As of April 1, 2007, the Company had notes receivable from Flash Partners of 11.0 billion Japanese yen, or approximately $94 million based upon the exchange rate at April 1, 2007. These notes are secured by the equipment purchased by Flash Partners using the note proceeds.

Flash Alliance. The Company has a 49.9% ownership interest in Flash Alliance Ltd. (“Flash Alliance”), a business venture with Toshiba, formed in fiscal 2006. In the venture, the Company and Toshiba will collaborate in the development and manufacture of NAND flash memory products.

⁽¹⁾		The maximum amount of the Company’s contingent indemnification or guarantee obligation, net of payments and any lease adjustments based upon the exchange rate at April 1, 2007.

FlashVision. In May 2002, FlashVision secured an equipment lease arrangement of approximately 37.9 billion Japanese yen, or approximately $322 million based upon the exchange rate at April 1, 2007, with Mizuho Leasing, and other financial institutions. On May 31, 2006, FlashVision refinanced the remaining balance of this equipment lease arrangement. The refinanced arrangement was approximately 15.0 billion Japanese yen, or approximately $128 million based upon the exchange rate at April 1, 2007. Lease payments are due quarterly and are scheduled to be completed in February 2009 and a residual payment of 3.1 billion Japanese yen, or $26 million based upon the exchange rate at April 1, 2007, will be due in May 2009. Under the terms of the refinanced lease, Toshiba guaranteed these commitments on behalf of FlashVision. The Company agreed to indemnify Toshiba for certain liabilities Toshiba incurs as a result of Toshiba’s guarantee of the FlashVision equipment lease arrangement. If FlashVision fails to meet its lease commitments, and Toshiba fulfills these commitments under the terms of Toshiba’s guarantee, then the Company will be obligated to reimburse Toshiba for 49.9% of any claims and associated expenses under the lease, unless the claims result from Toshiba’s failure to meet its obligations to FlashVision or its covenants to the lenders. Because FlashVision’s equipment lease arrangement is denominated in Japanese yen, the maximum amount of the Company’s contingent indemnification obligation on a given date when converted to U.S. dollars will fluctuate based on the exchange rate in effect on that date. As of April 1, 2007, the maximum amount of the Company’s contingent indemnification obligation, which reflects payments and any lease adjustments, was approximately 5.0 billion Japanese yen, or approximately $43 million based upon the exchange rate at April 1, 2007.

Flash Partners. Flash Partners sells and leases-back from a consortium of financial institutions a portion of its tools and has entered into five equipment master lease agreements totaling approximately 275.0 billion Japanese yen, or approximately $2.3 billion based upon the exchange rate at April 1, 2007. As of April 1, 2007, Flash Partners had drawn down approximately 245 billion Japanese yen, or approximately $2.1 billion based upon the exchange rate at April 1, 2007, of which 215 billion Japanese yen, or approximately $1.8 billion based upon the exchange rate at April 1, 2007, was outstanding at April 1, 2007. The Company and Toshiba have each guaranteed, on a several basis, 50% of Flash Partners’ obligations under the master lease agreements. As of April 1, 2007, the maximum amount of the Company’s guarantee obligation of the Flash Partners master lease agreements, which reflects payments and any lease adjustments, was approximately 107.4 billion Japanese yen, or approximately $915 million based upon the exchange rate at April 1, 2007. Lease payments are due quarterly or semi-annually and are scheduled to be completed in stages through fiscal 2011. At the end of each of the lease terms, Flash Partners has the option of purchasing the tools from the lessors. Flash Partners is obligated to insure the equipment, maintain the equipment in accordance with the manufacturers’ recommendations and comply with other customary terms to protect the leased assets. The master lease agreements contains covenants that require the Company to maintain a minimum shareholder equity balance of $1.16 billion as well as a long-term loan rating of BB- or Ba3, based on a named independent rating service. In addition, the master lease

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Cont’d)

agreements contain customary events of default for a Japanese lease facility. The master lease agreements are exhibits to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006. These agreements should be read carefully in their entirety for a comprehensive understanding of their terms and the nature of the obligations the Company guaranteed. The fair value of the Company’s guarantee of Flash Partners’ lease obligation was insignificant at inception of the guarantee. In addition, Flash Partners expects to secure additional equipment lease facilities over time, which the Company may be required to guarantee in whole or in part.

Guarantees

Indemnification Agreements. The Company has agreed to indemnify suppliers and customers for alleged patent infringement. The scope of such indemnity varies, but may, in some instances, include indemnification for damages and expenses, including attorneys’ fees. The Company may periodically engage in litigation as a result of these indemnification obligations. The Company’s insurance policies exclude coverage for third-party claims for patent infringement. Although the liability is not remote, the nature of the patent infringement indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its suppliers and customers. Historically, the Company has not made any significant indemnification payments under any such agreements. As of April 1, 2007, no amount had been accrued in the accompanying condensed consolidated financial statements with respect to these indemnification guarantees.

As permitted under Delaware law and the Company’s charter and bylaws, the Company has agreements whereby it indemnifies certain of its officers and each of its directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a Director and Officer insurance policy that may reduce its exposure and enable it to recover all or a portion of any future amounts paid. As a result of its insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. The Company has no liabilities recorded for these agreements as of April 1, 2007 or January 1, 2006, as this liability is not reasonably estimable even though liability under these agreements is not remote.

The Company and Toshiba have agreed to mutually contribute to, and indemnify each other, Flash Partners and Flash Alliance, for environmental remediation costs or liability resulting from Flash Partners or Flash Alliance’s manufacturing operations in certain circumstances. In fiscal 2004 and 2006, respectively, the Company and Toshiba each engaged consultants to perform a review of the existing environmental conditions at the site of the facility at which Flash Partners operations are located and Flash Alliance operations will be located to establish a baseline for evaluating future environmental conditions. The Company and Toshiba have also entered into a Patent Indemnification Agreement under which in many cases the Company will share in the expenses associated with the defense and cost of settlement associated with such claims. This agreement provides limited protection for the Company against third-party claims that NAND flash memory products manufactured and sold by Flash Partners or Flash Alliance infringe third-party patents. The Company has not made any indemnification payments under any such agreements and as of April 1, 2007, no amounts have been accrued in the accompanying condensed consolidated financial statements with respect to these indemnification guarantees.

The allocation of the purchase price may be subject to change based on final estimates of fair value, primarily related to acquisition-related restructuring, deferred taxes and actual transaction costs. In the first quarter of fiscal 2007, the Company booked an adjustment to the net tangible assets acquired of approximately $57.4 million, largely related to a revised estimate of the assumed Hynix Semiconductor, Inc. (“Hynix”) deferred purchase credits.

Purchase Price Allocation. In accordance with SFAS 141, the total preliminary purchase price was allocated to msystems net tangible and intangible assets based upon their estimated fair values as of November 19, 2006. The excess purchase price over the value of the net tangible and identifiable intangible assets was recorded as goodwill. The fair values assigned to tangible and intangible assets acquired and liabilities assumed are based on estimates and assumptions of management which included a third party appraisal. Some of these estimates are subject to change, particularly those estimates relating to potential restructuring activities, deferred taxes and actual transaction costs.

Acquisition-Related Restructuring. During the fourth quarter of fiscal 2006, the Company established its plans to integrate the msystems operations, which included the involuntary termination of approximately 100 employees and exiting duplicative facilities, and recorded $1.6 million for acquisition-related restructuring activities, of which, $0.3 million relates to excess lease obligations and $1.3 million is related to personnel. The lease obligations extend through the end of the lease term in fiscal 2009. These acquisition-related restructuring liabilities were included in the purchase price allocation of the cost to acquire msystems. In the first quarter of fiscal 2007, the Company reversed through goodwill approximately $0.5 million of the restructuring accrual based on actual costs being less than the original estimates. As of April 1, 2007, there is approximately $0.4 million remaining of the acquisition-related restructuring accrual that has not been paid or utilized.

In-process Technology. As part of the msystems purchase agreement, a certain amount of the purchase price was allocated to acquired in-process technology, which was determined through established valuation techniques in the high-technology industry and written-off in the fourth quarter of fiscal 2006 because technological feasibility had not been established and no alternative future uses existed. The value was determined by estimating the net cash flows and discounting forecasted net cash flows to their present values. The Company wrote-off the acquired in-process technology of $186.0 million in the fourth quarter of fiscal 2006. As of April 1, 2007, it was estimated that these in-process projects would be completed at an estimated total cost of $19.2 million. The net cash flows from the identified projects were based on estimates of revenues, costs of revenues, research and development expenses, including costs to complete the projects, selling, marketing and administrative expenses, and income taxes from the projects. The Company believes the assumptions used in the valuations were reasonable at the time of the acquisition. The estimated net revenues and gross margins were based on management’s projections of the projects and were in line with industry averages. Estimated total net revenues from the projects were expected to grow through fiscal 2009 and decline thereafter as other new products are expected to become available. Estimated operating expenses included research and development expenses and selling, marketing and administrative expenses based upon historical and expected direct expense level and general industry metrics. Estimated research and development expenses included costs to bring the projects to technological feasibility and costs associated with ongoing maintenance after a product is released. These activities are approximately 2% of msystems’ portion of the Company’s net revenues for the in-process technologies.

The effective tax rate used in the analysis of the in-process technologies reflects a historical industry-specific average for the United States federal income tax rates. A discount rate (the rate utilized to discount the net cash flows to their present values) of 19% was used in computing the present value of net cash flows for the projects. The percentage of completion was determined using costs incurred by msystems prior to the acquisition date compared to the estimated remaining research and development to be completed to bring the projects to technological feasibility.

Matrix Semiconductor, Inc. On January 13, 2006, the Company completed the acquisition of Matrix Semiconductor, Inc. (“Matrix”), a designer and developer of three-dimensional (3-D) integrated circuits. Matrix^® 3-D Memory is used for one-time programmable storage applications that complement the Company’s existing flash storage memory products. The Company acquired 100% of the outstanding shares of Matrix for a total purchase price of $296.4 million.

The purchase price is comprised of the following (in thousands):


Fair value of SanDisk common stock issued	$	242,303
Estimated fair value of options assumed		33,169
Cash consideration		20,000
Direct transaction costs		907

Total estimated purchase price	$	296,379

Acquisition-Related Restructuring. During the first quarter of fiscal 2006, the Company established its plans to integrate the Matrix operations, which included exiting duplicative facilities and recorded $17.5 million for acquisition-related restructuring activities, of which $17.4 million relates to excess lease obligations. The lease obligations extend through the end of the lease term in 2016. These acquisition-related restructuring liabilities were included in the purchase price allocation of the cost to acquire Matrix. As of April 1, 2007, the outstanding accrual balance was $16.0 million. The reduction in the accrual balance was primarily related to excess lease obligation payments.

In-process Technology. As part of the Matrix purchase agreement, a certain amount of the purchase price was allocated to acquired in-process technology, which was determined through established valuation techniques in the high-technology computer industry and written off in the first quarter of fiscal 2006 because technological feasibility had not been established and no alternative future uses existed. The value was determined by estimating the net cash flows and discounting forecasted net cash flows to their present values. The Company wrote-off the acquired in-process technology of $39.6 million in the first quarter of fiscal 2006. As of April 1, 2007, it was estimated that these in-process projects would be completed over the next one to two years at an estimated total cost of $8 million.

The net cash flows from the identified projects were based on estimates of revenues, costs of revenues, research and development expenses, including costs to complete the projects, selling, marketing and administrative expenses, and income taxes from the projects. The Company believes the assumptions used in the valuations were reasonable at the time of the acquisition. The estimated net revenues and gross margins were based on management’s projections of the projects and were in line with industry averages. Estimated total net revenues from the projects were expected to grow through fiscal 2009 and decline thereafter as other new products are expected to become available. Estimated operating expenses included research and development expenses and selling, marketing and administrative expenses based upon historical and expected direct expense level and general industry metrics. Estimated research and development expenses included costs to bring the projects to technological feasibility and costs associated with ongoing maintenance after a product is released. These activities range from 0% to 5% of Matrix’s portion of the Company’s net revenues for the in-process technologies.

The effective tax rate used in the analysis of the in-process technologies reflects a historical industry-specific average for the United States federal income tax rates. Discount rates (the rates utilized to discount the net cash flows to their present values) ranging from 12.5% to 15.5% were used in computing the present value of net cash flows for the projects. The percentage of completion was determined using costs incurred by Matrix prior to the acquisition date compared to the estimated remaining research and development to be completed to bring the projects to technological feasibility.

13. Income Taxes

The Company recorded tax provisions of $12.2 million and $41.3 million for the three months ended April 1, 2007 and April 2, 2006, respectively, or effective tax rates of 72.6% and 54.0% for the three months ended April 1, 2007 and April 2, 2006, respectively. Our effective tax rate for the first quarter of fiscal 2007 differed from the statutory federal rate of 35.0% primarily due to the impact of state taxes, stock option compensation adjustments recorded under Statement of Financial Accounting Standards No. 123(R), Share Based Payments, tax exempt interest income, research and development tax credits, the tax impact of acquisition-related intangible amortization taxed at rates lower than federal rates and certain other tax items recognized in the quarter, including a net adjustment of $3.4 million primarily related to the prior year.

The Company adopted FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 at the beginning of fiscal 2007. As a result of the implementation of FIN 48 the Company recognized approximately a $1.0 million increase in the liability for unrecognized tax benefits, which was accounted for as a reduction to the January 1, 2007, balance of retained earnings. The total taxes payable of $44.0 million on uncertain tax positions is before federal tax benefit of state income taxes of $6.1 million. Of the net taxes payable of $37.9 million, $33.2 million would favorably impact the effective tax rate in future periods and $4.7 million would increase capital in excess of par value. The Company expects to recognize a $0.6 million tax benefit within the next 12 months as a result of the expiration of statutes of limitation. The Company will continue to recognize interest and/or penalties related to income taxes in income tax expense of which a $5.0 million accrual was outstanding as of the date of adoption and an additional $0.5 million was recorded in the three months ended April 1, 2007.

The Company is subject to U.S. federal income tax as well as income taxes in many state and foreign jurisdictions. The federal statute of limitations on assessment remains open for the tax years 2003 through 2006 and the statute of limitations in state jurisdictions remain open generally from tax years 2002 through 2006. The major foreign jurisdictions remain open for examination generally for tax years 2001 through 2006. The Company also had federal and state net operating loss carryforwards of approximately $89 million and $52 million before federal benefit, respectively, at December 31, 2006.

The tax benefit associated with the exercise of stock options for the three months ended April 1, 2007 and April 2, 2006 was credited to capital in excess of par value in the amount of $2.1 million and $41.9 million, respectively, when realized. On adoption of FIN 48, the Company recorded a $4.7 million reduction in capital in excess of par value.

14. Litigation

From time-to-time, it has been and may continue to be necessary to initiate or defend litigation against third parties. These and other parties could bring suit against us. In each case listed below where we are the defendant, we intend to vigorously defend the action.

On October 31, 2001, the Company filed a complaint for patent infringement in the United States District Court for the Northern District of California against Memorex Products, Inc., Pretec Electronics Corporation, Ritek Corporation, and Power Quotient International Co., Ltd. In the suit, captioned SanDisk Corp. v. Memorex Products, Inc., et al., Civil Case No. CV 01 4063 VRW, the Company seeks damages and injunctions against these companies from making, selling, importing or using flash memory cards that infringe its U.S. Patent No. 5,602,987. The District Court granted summary judgment of non-infringement in favor of defendants Ritek, Pretec and Memorex and entered judgment on May 17, 2004. On June 2, 2004, the Company filed a notice of appeal of the summary judgment rulings to the United States Court of Appeals for the Federal Circuit. On July 8, 2005, the Federal Circuit held in favor of the Company, vacating the judgment of non-infringement and remanding the case back to the District Court. The District Court issued an order on claim construction on February 22, 2007. No trial date has been set for this case.

On or about June 9, 2003, the Company received written notice from Infineon Technologies AG, or Infineon, that it believes the Company has infringed its U.S. Patent No. 5,726,601 (the ‘601 patent). On June 24, 2003, the Company filed a complaint against Infineon for a declaratory judgment of patent non-infringement and invalidity regarding the ‘601 patent in the United States District Court for the Northern District of California, captioned SanDisk Corporation v. Infineon Technologies AG, a German corporation, et al., Civil Case No. C 03 02931 BZ. On October 6, 2003, Infineon filed an answer and counterclaim: (a) denying that the Company is entitled to the declaration sought by the Company’s complaint; (b) requesting that the Company be adjudged to have infringed, actively induced and/or contributed to the infringement of the ’601 patent and an additional patent, U.S. Patent No. 4,841,222 (the ’222 patent). On August 12, 2004, Infineon filed an amended counterclaim for patent infringement alleging that the Company infringes U.S. Patent Nos. 6,026,002 (the ’002 patent); 5,041,894 (the ’894 patent); and 6,226,219 (the ’219 patent), and omitting the ’601 and ’222 patents. On August 18, 2004, the Company filed an amended complaint against Infineon for a declaratory judgment of patent non-infringement and invalidity regarding the ’002, ’894, and ’219 patents. On February 9, 2006, the Company filed a second amended complaint to include claims for declaratory judgment that the ’002, ’894 and ’219 patents are unenforceable. On March 17, 2006, the Court granted a stipulation by the parties withdrawing all claims and counterclaims regarding the ’002 patent. On February 20, 2007, the Court entered an order staying the case to facilitate settlement negotiations.

On February 20, 2004, the Company and a number of other manufacturers of flash memory products were sued in the Superior Court of the State of California for the City and County of San Francisco in a purported consumer class action captioned Willem Vroegh et al. v. Dane Electric Corp. USA, et al., Civil Case No. GCG 04 428953, alleging false advertising, unfair business practices, breach of contract, fraud, deceit, misrepresentation and violation of the California Consumers Legal Remedy Act. The lawsuit purports to be on behalf of a class of purchasers of flash memory products and claims that the defendants overstated the size of the memory storage capabilities of such products. The lawsuit seeks restitution, injunction and damages in an unspecified amount. The parties have reached a settlement of the case, which is pending final court approval. In April 2006, the Court issued an order preliminarily approving the settlement. In August 2006, the Court held a hearing to consider final approval of the settlement, and on November 20, 2006, the Court issued its formal written order of approval. Two objectors to the settlement have filed separate appeals from the Court’s order granting final approval.

On October 15, 2004, the Company filed a complaint for patent infringement and declaratory judgment of non-infringement and patent invalidity against STMicroelectronics N.V. and STMicroelectronics, Inc. (collectively, “ST”) in the United States District Court for the Northern District of California, captioned SanDisk Corporation v. STMicroelectronics, Inc., et al., Civil Case No. C 04 04379JF. The complaint alleges that ST’s products infringe one of the Company’s U.S. patents and seeks damages and an injunction. The complaint further seeks a declaratory judgment that the Company does not infringe several of ST’s U.S. patents. On January 20, 2005, the District Court issued an order granting ST’s motion to dismiss the declaratory judgment causes of action based on lack of subject matter jurisdiction. The Company appealed this decision to the U.S. Court of Appeals for the Federal Circuit. On March 26, 2007, the United States Court of Appeals for the Federal Circuit reversed the District Court’s ruling and remanded the case to the district court for further proceedings. The case is presently stayed until June 11, 2007.

On October 15, 2004, the Company filed a complaint under Section 337 of the Tariff Act of 1930 (as amended) (Case No. 337-TA 526) titled, “In the matter of certain NAND flash memory circuits and products containing same” in the United States International Trade Commission (“ITC”), naming STMicroelectronics N.V. and STMicroelectronics, Inc. (collectively, “ST”) as respondents. In the complaint, the Company alleges that ST’s NAND flash memory infringes U.S. Patent No. 5,172,338 (the ’338 patent), and seeks an order excluding ST’s products from importation into the United States. On November 15, 2004, the ITC instituted an investigation pursuant to 19 U.S.C. § 1337 against ST in response to the Company’s complaint. On December 9, 2004, ST filed a response to the complaint, denying that they infringe the ’338 patent and alleging that the patent is invalid and/or unenforceable. A hearing was held from August 1-8, 2005. On October 19, 2005, the Administrative Law Judge issued an initial determination confirming the validity and enforceability of the Company’s ’338 patent by rejecting ST’s claims that the patent was invalidated by prior art. The initial determination, however, found that ST’s NAND flash memory chips did not infringe the asserted claims of the ’338 patent. On October 31, 2005, the Company filed a petition with the ITC to review and reverse the finding of non-infringement. Also, on October 31, 2005, ST filed a petition for review with the ITC to review and reverse the finding that the patent was valid and enforceable. On December 6, 2005, the ITC issued its decision. The ITC declined to review the finding of non-infringement, and, after reviewing the finding of validity, declined to take any position on the issue of validity. The Company appealed the ITC’s decision to the U.S. Court of Appeals for the Federal Circuit and the Federal Circuit affirmed the ITC’s decision on March 6, 2007.

On February 4, 2005, STMicro filed two complaints for patent infringement against the Company in the United States District Court for the Eastern District of Texas, captioned STMicroelectronics, Inc. v. SanDisk Corporation, Civil Case No. 4:05CV44 (the “’44 Action”), and STMicroelectronics, Inc. v. SanDisk Corporation, Civil Case No. 4:05CV45 (the “’45 Action”), respectively. The complaints seek damages and injunctions against certain SanDisk products. On April 22, 2005, the Company filed counterclaims on two patents against STMicroelectronics N.V. and STMicroelectronics, Inc. (collectively, “ST”) in the ’45 Action. The counterclaims seek damages and injunctive relief against ST’s flash memory products. In the ’44 Action, the District Court granted SanDisk’s motion for summary judgment of non-infringement on all accused products. ST has filed a motion to amend or correct the final judgment but no ruling has issued. On February 6, 2007, the District Court dismissed the ’44 Action with prejudice, ordered that ST take nothing from the Company, and that costs be taxed against ST. In the ’45 Action, the parties have filed motions for summary judgment regarding various aspects of the litigation. The magistrate judge has made recommendations on some but not all issues raised on summary judgment, but the trial judge has not made any final decisions on the magistrate judge’s recommendations. On March 26, 2007, the trial judge issued an order to stay the ’45 Action for 90 days. The court will address the schedule for remaining activities in the case shortly before the end of the stay period.

On October 14, 2005, STMicroelectronics, Inc. (“STMicro”) filed a complaint against the Company and the Company’s CEO Eli Harari, in the Superior Court of the State of California for the County of Alameda, captioned STMicroelectronics, Inc. v. Harari, Case No. HG 05237216 (the “Harari Matter”). The complaint alleges that STMicro, as the successor to Wafer Scale Integration, Inc.’s (“WSI”) legal rights, has an ownership interest in several SanDisk patents that issued from applications filed by Dr. Harari, a former WSI employee. The complaint seeks the assignment or co-ownership of certain inventions and patents conceived of by Harari, including some of the patents asserted by the Company in its litigations against STMicro, as well as damages in an unspecified amount. On November 15, 2005, Harari and the Company removed the case to the U.S. District Court for the Northern District of California, where it was assigned case number C05-04691. On December 13, 2005, STMicro filed a motion to remand the case back to the Superior Court of Alameda County. The case was remanded to the Superior Court of Alameda County on July 18, 2006, after briefing and oral argument on a motion by STMicro for reconsideration of an earlier order denying STMicro’s request for remand. Due to the remand, the District Court did not rule upon a summary judgment motion previously filed by the Company. In the Superior Court of Alameda County, the Company filed a Motion to Transfer Venue to Santa Clara County on August 10, 2006, which was denied on September 12, 2006. On October 6, 2006, the Company filed a Petition for Writ of Mandate with the First District Court of Appeal which asks that the Superior Court’s September 12 Order be vacated, and the case transferred to Santa Clara County. On October 20, 2006, the Court of Appeal requested briefing on the Company’s petition for a writ of mandate and stayed the action during the pendency of the writ proceedings. On January 17, 2007, the Court of Appeal issued an alternative writ directing the Superior Court to issue a new order granting the Company’s venue transfer motion or to show cause why a writ of mandate should not issue compelling such an order. On January 23, 2007, the Superior Court of Alameda transferred the case to Santa Clara County as a result of the writ proceeding at the Court of Appeal. The Company also filed a special motion to strike ST’s unfair competition claim, which the Superior Court denied on September 11, 2006. The Company has appealed the denial of that motion, and the proceedings at the Superior Court are stayed during the pendency of the appeal.

On December 6, 2005, the Company filed a complaint for patent infringement in the United States District Court for the Northern District of California against STMicroelectronics, Inc. and STMicroelectronics, NV (collectively, “ST”) (Case No. C0505021 JF). In the suit, the Company seeks damages and injunctions against ST from making, selling, importing or using flash memory chips or products that infringe the Company’s U.S. Patent No. 5,991,517 (the “’517 patent). The case is presently stayed, pending the termination of the ITC investigation instituted February 8, 2006, discussed below.

On January 10, 2006, the Company filed a complaint under Section 337 of the Tariff Act of 1930 (as amended) (Case No. 337-TA-560) titled, “In the matter of certain NOR and NAND flash memory devices and products containing same” in the ITC, naming ST as respondents. In the complaint, the Company alleges that: (i) ST’s NOR flash memory infringes the ”338 patent; (ii) ST’s NAND flash memory infringes U.S. Patent No. 6,542,956 (the “’956 patent”); and (iii) ST’s NOR flash memory and NAND flash memory infringe the ’517 patent. The complaint seeks an order excluding ST’s NOR and NAND flash memory products from importation into the United States. The ITC instituted an investigation, based on the Company’s complaint, on February 8, 2006. On March 31, 2006, ST filed a motion for partial summary determination or termination of the investigation with respect to the ’338 patent. On May 1, 2006, the Administrative Law Judge (“ALJ”) denied ST’s motion in an initial determination that is subject to review by the ITC. On May 17, 2006, SanDisk filed a motion to voluntarily terminate the investigation with respect to the ’956 patent. On June 1, 2006, the ALJ issued an Initial Determination granting the Company’s motion. On August 15, 2006, the ALJ set December 4, 2006 as the date for the hearing, April 4, 2007 for the Initial Determination, and August 13, 2007 as the target date for completion of the investigation. On September 12, 2006, the Company filed a motion to voluntarily terminate the investigation with respect to claims 1, 2, and 4 of the ’517 patent. On October 10, 2006, the ALJ issued an Initial Determination granting the Company’s motion with respect to claims 2 and 4 of the ’517 patent. On September 25, 2006, ST filed motions for summary determination of non-infringement of the ’338 patent with respect to its current products and non-infringement of the ’338 and ’517 patents with respect to prospective products and of lack of domestic industry with regard to the ’338 patent. On the same date, SanDisk filed a motion for summary determination of the economic prong of the domestic industry requirement with regard to the ’517 patent. On November 17, 2006, the ALJ granted SanDisk’s motion for summary determination of the economic prong of domestic industry, and denied ST’s motion for summary determination of lack of domestic industry with regard to the ’338 patent. The ALJ denied one of ST’s motions for summary determination of noninfringement of the ’338 patent. The ALJ granted ST’s motion for summary determination with respect to ST’s binary NOR products, which SanDisk was no longer accusing, and terminated the investigation with respect to certain prospective products. On November 28, 2006, the ALJ denied ST’s second motion for summary determination of non-infringement of the ’338 patent. The ALJ then held an evidentiary hearing from December 1, 2006 through December 15, 2006. On January 16, 2007, the ALJ extended the due date of the initial determination due to June 1, 2007.

On or about July 15, 2005, Societa’ Italiana Per Lo Sviluppo Dell’electtronica, S.I.Sv.El., S.p.A., (“Sisvel”) filed suit against the Company and others in the district court of the Netherlands in The Hague in a case captioned Societa’ Italiana Per Lo Sviluppo Dell’electtronica, S.I.Sv.El., S.p.A. adverse to SanDisk International Sales, Moduslink B.V. and UPS SCS (Nederland) B.V., Case No. 999.131.1804 (Cause List numbers 2006/167 and 2006/168). Sisvel alleges that certain of the Company’s MP3 products infringe three European patents of which Sisvel claims to be a licensee with the right to bring suit. Sisvel seeks an injunction and unspecified damages. Sisvel has previously publicly indicated that it will license these and other patents under reasonable and nondiscriminatory terms, and it has specifically offered the Company a license under the patents. The Company has submitted its answer on the substance of Sisvel’s claim. In March 2007, the Company and Sisvel entered into a confidential agreement settling this matter and all related matters, including those described below. Accordingly, all claims and counterclaims between the parties have been dismissed.

In a related action, on March 9, 2006, the Company filed an action in the English High Court, Chancery Division, Patents Court, in London, against Sisvel and the owners of the patents Sisvel has asserted against the Company in the Netherlands. The case is SanDisk Corporation v. Koninklijke Philips Electronics N.V. (a Dutch corporation), France Télécom (a French corporation), Télédiffusion de France S.A. (a French corporation), Institut für Rundfunktechnik GmbH (a German corporation) and Societa’ Italiana Per Lo Sviluppo Dell’electtronica, S.I.Sv.El., S.p.A., Case No. HC 06 C 00835. In this action, the Company seeks a declaration of non-infringement of the patents asserted by Sisvel in connection with the Company’s MP3 products. The Company also seeks a declaration that the patents are not “essential” to the technology of MP3 players, as Sisvel presently contends in the case filed in the Netherlands. The defendants have submitted their formal defense and counterclaimed for infringement. As described above, in March 2007, the Company and Sisvel entered into a confidential agreement settling this matter and all related matters. Accordingly, all claims and counterclaims between the parties have been dismissed.

In another related action, on April 13, 2006, Audio MPEG filed a complaint alleging patent infringement in the District Court for the Eastern District of Virginia. The case is Audio MPEG v. SanDisk Corporation, Case No. 2:06cv209 WDK/JEB. Audio MPEG holds itself out to be the U.S. subsidiary of Sisvel and purports to have the right to enforce certain patents in the U.S. on subject matter related to the patents asserted by Sisvel in the Netherlands. Specifically, Audio MPEG asserts U.S. Patent No. 5,214,678 (entitled “Digital transmission system using subband coding of a digital signal”), U.S. Patent No. 5,323,396 (entitled “Digital transmission system, transmitter and receiver for use in the transmission system”), U.S. Patent No. 5,539,829 (entitled “Subband coded digital transmission system using some composite signals”), and U.S. Patent No. 5,777,992 (entitled “Decoder for decoding and encoded digital signal and a receiver comprising the decoder”). As described above, in March 2007, the Company and Sisvel entered into a confidential agreement settling this matter and all related matters. Accordingly, all claims and counterclaims between the parties have been dismissed.

In another related action, on April 13, 2006, Sisvel filed suit against the Company’s subsidiary, SanDisk GmbH, for patent infringement in the Mannheim District Court in Germany, S.I.Sv.El., S.p.A. v. SanDisk GmbH, file no. 7 O 90/06, which was served on the Company on or about May 10, 2006. The plaintiffs allege that certain of the Company’s MP3 products infringe four German patents of which Sisvel claims to be a licensee with the right to bring suit. Sisvel seeks an injunction and unspecified damages. Sisvel has previously publicly stated that it will license these and other patents under reasonable and nondiscriminatory terms, and it has specifically offered the Company a license under the patents. In a first trial in September of 2006, the Mannheim court expressed reservations about Sisvel’s claim of infringement and ordered further briefing and a resumption of the trial, which was held in January 2007. As described above, in March 2007, the Company and Sisvel entered into a confidential agreement settling this matter and all related matters. Accordingly, all claims and counterclaims between the parties have been dismissed.

In another related action, on April 13, 2006, Sisvel filed suit against the Company for patent infringement in the Mannheim District Court in Germany, S.I.Sv.El., S.p.A. v. SanDisk Corporation, file no. 7 O 89/06, which was served on the Company in or about July, 2006. The plaintiffs allege that certain of the Company’s MP3 products infringe four German patents of which Sisvel claims to be a licensee with the right to bring suit. Sisvel seeks an injunction and unspecified damages. Sisvel has previously publicly stated that it will license these and other patents under reasonable and nondiscriminatory terms, and it has specifically offered the Company a license under the patents. Both sides submitted initial pleadings and the court held a trial in January 2007. As described above, in March 2007, the Company and Sisvel entered into a confidential agreement settling this matter and all related matters. Accordingly, all claims and counterclaims between the parties have been dismissed.

On August 7, 2006, two purported shareholder class and derivative actions, captioned Capovilla v. SanDisk Corp., No. 106 CV 068760, and Dashiell v. SanDisk Corp., No. 106 CV 068759, were filed in the Superior Court of California in Santa Clara County, California. On August 9, 2006, and August 17, 2006, respectively, two additional purported shareholder class and derivative actions, captioned Lopiccolo v. SanDisk Corp., No. 106 CV 068946, and Sachs v. SanDisk Corp., No. 1-06-CV-069534, were filed in that court. These four lawsuits were subsequently consolidated under the caption In re msystems Ltd. Shareholder Litigation, No. 106 CV 068759 and on October 27, 2006, a consolidated amended complaint was filed that supersedes the four original complaints. The lawsuit is brought by purported shareholders of msystems and names as defendants the Company and each of msystems’ directors, including its President and Chief Executive Officer, and its former Chief Financial Officer (now its Chief Operating Officer), and names msystems as a nominal defendant. The lawsuit asserts purported class action and derivative claims. The alleged derivative claims assert, among other things, breach of fiduciary duties, abuse of control, constructive fraud, corporate waste, unjust enrichment and gross mismanagement with respect to past stock option grants. The alleged class and derivative claims also assert claims for breach of fiduciary duty by msystems’ board, which the Company is alleged to have aided an abetted, with respect to allegedly inadequate consideration for the merger, and allegedly false or misleading disclosures in proxy materials relating to the merger. The complaints seek, among other things, equitable relief, including enjoining the proposed merger, and compensatory and punitive damages.

On September 11, 2006, Mr. Rabbi, a shareholder of msystems Ltd. (“msystems”), filed a derivative action and a motion to permit him to file the derivative action against four directors of msystems and msystems, arguing that options were allegedly allocated to officers and employees of msystems in violation of applicable law. Mr. Rabbi claimed that the aforementioned actions allegedly caused damage to msystems. On October 17, 2006, msystems filed a motion to change its title in the motion to permit the filing of the derivative action from a “Formal Respondent” to a “Respondent,” and Mr. Rabbi has consented to this motion. msystems received an extension of time to file its response to the motion until March 25, 2007. On January 25, 2007, msystems filed a motion to dismiss the motion to seek leave to file the derivative action and the derivative action on the grounds, inter alia, that Mr. Rabbi ceased to be a shareholder of msystems after the merger between msystems and the Company.

15. Condensed Consolidating Financial Statements

As part of the acquisition of msystems in November 2006, the Company entered into a supplemental indenture whereby the Company became an additional obligor and guarantor of the assumed $75 million 1% Convertible Notes due 2035 issued by msystems Finance Company, (the “Subsidiary Issuer” or “mfinco”) and guaranteed by SanDisk Israel Ltd. (the ”Other Guarantor Subsidiary” or formerly “msystems”). SanDisk Corporation’s (the “Parent Company” or the “Company”) guarantee is full and unconditional, jointly and severally with msystems. Both msystems and mfinco are wholly-owned subsidiaries of the Company. The following condensed consolidating financial statements present separate information for mfinco as the original issuer, the Company and msystems as guarantors and the Company’s other combined non-guarantor subsidiaries, and should be read in conjunction with the condensed consolidated financial statements of the Company.

These condensed consolidating financial statements have been prepared using the equity method of accounting. Earnings of subsidiaries are reflected in the Company’s investment in subsidiaries account. The elimination entries eliminate investments in subsidiaries, related stockholders’ equity and other intercompany balances and transactions. Only the three months ended April 1, 2007 are presented for the statements of operations and cash flows as the inception of the guarantee by the Company coincides only with the consummation of the acquisition of msystems on November 19, 2006.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Statements in this report, which are not historical facts, are forward-looking statements within the meaning of the federal securities laws. These statements may contain words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates” or other wording indicating future results or expectations. Forward-looking statements are subject to significant risks and uncertainties. Our actual results may differ materially from the results discussed in these forward-looking statements. Factors that could cause our actual results to differ materially include, but are not limited to, those discussed under “Risk Factors” and elsewhere in this report. Our business, financial condition or results of operations could be materially adversely affected by any of these factors. We undertake no obligation to revise or update any forward-looking statements to reflect any event or circumstance that arises after the date of this report, except as required by law. References in this report to “SanDisk^{^®},” “we,” “our,” and “us” refer collectively to SanDisk Corporation, a Delaware corporation, and its subsidiaries.

Overview

We are one of the world’s largest suppliers of NAND flash-based data storage products for the consumer, mobile communications, and industrial markets. Our mission is to be the preferred choice of personal storage solutions for the worldwide digital economy. We seek to achieve our mission by developing leading technologies and innovative products and delivering our products through both OEM and retail channels.

We design, develop, market and manufacture products and solutions in a variety of form factors using our flash memory, controller, and firmware technologies. Our products are used in a wide range of consumer electronics devices such as digital cameras, mobile phones, USB drives, gaming consoles, MP3 players and other digital devices. Our products are also embedded in a variety of systems for the enterprise, industrial, military and other markets. Flash storage technology allows data to be stored in a low-power consumption, durable and compact format that retains the data after the power has been turned off.

Our results are primarily driven by worldwide demand for flash storage devices, which in turn depends on end-user demand for electronic products. We believe the market for flash storage is price elastic. Accordingly, we expect that as we reduce the price of our flash devices, consumers will demand an increasing number of megabytes of memory. In order to profitably capitalize on price elasticity of demand in the market for flash storage products, we must reduce our cost per megabyte at a rate similar to the change in selling price per megabyte to the consumer. We seek to achieve these cost reductions through technology improvements primarily focused on increasing the amount of memory stored in a given area of silicon.

During the first quarter of fiscal 2007, the NAND flash industry has been in an over supply situation leading to aggressive price declines. This pricing environment is putting pressure on our margins and in response, we implemented a restructuring plan which primarily included reductions of our workforce. To lower operational expenses, the restructuring plan eliminated certain redundant resources in all functions of the organization worldwide and closed certain facilities in order to reduce our cost structure. For further discussion on our restructuring plan, please refer to Note 4, “Restructuring.”

We adopted Financial Accounting Standards Board, or FASB, Interpretation No. 48, or FIN 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 at the beginning of fiscal 2007. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. Adoption of FIN 48 did not have a significant impact on our financial position and result of operations. For further discussion on adoption of FIN 48, please refer to Note 13, “Income Taxes.”

OEM		345.5		165.6		109	%

Product revenues	$	689.4	$	537.7		28	%

The decrease in our retail product revenues for the three months ended April 1, 2007 compared to the three months ended April 2, 2006 was due to price declines more than offsetting the growth in units and average memory capacity of our products. Our average retail selling price per megabyte declined 67% in the three months ended April 1, 2007 over the comparable period in fiscal 2006 due to excess industry supply, which resulted in very competitive retail pricing. In most cases our retail prices were still higher than the competition during the first quarter of fiscal 2007. OEM product revenues increased primarily due to our November 2006 acquisition of msystems Ltd., or msystems, and increased sales of our memory products for mobile phones. Sales of our consolidated TwinSys Ltd., or TwinSys, venture with Toshiba Corporation, or Toshiba, were $53 million for the three months ended April 1, 2007, however, these sales will be eliminated in future periods as the venture terminated operations on March 31, 2007. We expect to continue to reduce our price per megabyte as technology advances allow us to further reduce our cost per megabyte.

Our top ten customers represented approximately 57% of our total revenues in the three months ended April 1, 2007, compared to 49% in the three months ended April 2, 2006. Customers who exceeded 10% of our total revenues in the three months ended April 1, 2007 were Sony Ericsson Mobile Communications AB, or Sony Ericsson, and Samsung Electronics Co. Ltd., or Samsung, which were 13% and 11% of our total revenues, respectively. In the three months ended April 2, 2006, Samsung accounted for 14% of our total revenues.

Product revenues for the three month period ended April 1, 2007 over the comparable period in fiscal 2006 grew significantly in Japan due to the acquired msystems’ TwinSys venture and our 3-D gaming business. The growth in the Asia-Pacific region primarily reflects higher sales to handset OEM customers and their subcontract manufacturers that are bundling our flash memory cards with music and camera enabled handsets. The decrease in the Europe and Middle East regions primarily reflects the aggressive retail price declines that were larger than the substantial increase in unit sales.

	April 1, 2007		April 2, 2006		Change
	(In millions, except percentages)
License and royalty revenues	$	96.7	$	85.6		13	%

The increase in our license and royalty revenues for the three months ended April 1, 2007 was primarily driven by increased overall sales by our licensees as well as increased royalties related to licensee sales of multi-level-cell, or MLC, based products.

Gross Margin.


	Three months ended
							Percent

Product gross margin (as a percent of product revenues)		14.2	%		28.4	%
Total gross margin (as a percent of total revenues)		24.8	%		38.2	%

The 14.2 point decrease in product gross margin percentage for the three months ended April 1, 2007 over the comparable period in fiscal 2006 was primarily due to a reduction in the average selling price per megabyte that was not fully offset by a decrease in the cost per megabyte. The aggressive price declines were primarily the result of competition caused by oversupply in the NAND component market. Product gross margin as a percentage of revenues was also negatively impacted by 2.7 points from the addition of amortization of acquisition-related intangibles of $21.1 million primarily from the msystems acquisition in November 2006, increased inventory charges primarily as a result of our cost being higher than our expected average selling prices for our products, and by 0.4 points from an increase in stock compensation expense of $3.2 million related to the adoption of Statement of Financial Accounting Standards No. 123(R), or SFAS 123(R), Share Based Payments, which was primarily recorded in inventory in the first quarter of fiscal 2006. In the three months ended April 1, 2007 and April 2, 2006, we sold approximately $2.4 million and $13.1 million, respectively, of inventory that had been fully written-off or reserved at the end of the previous fiscal year.

As part of the Matrix Semiconductor, Inc., or Matrix, acquisition in the first quarter of fiscal 2006, a portion of the purchase price was allocated to acquired in-process technology, which was determined through established valuation techniques in the high-technology industry and written-off at the date of acquisition because technological feasibility had not been established and no alternative future uses existed. The value was determined by estimating the net cash flows and discounting forecasted net cash flows to their present values. As of April 1, 2007, it was estimated that Matrix in-process projects would be completed over the next one to two years at an estimated total cost of approximately $8 million. For further discussion on write-off of acquired in-process technology, please refer to Note 12, “Business Acquisitions.”

During the first quarter of fiscal 2007, we implemented a restructuring plan which included reductions of our workforce in all functions of the organization worldwide and closure of redundant facilities in order to reduce our cost structure. A restructuring charge of $6.5 million was recorded, of which $5.9 million related to severance and benefits to 149 terminated employees. All expenses associated with our restructuring plan were recorded and are included in “Restructuring” in the Condensed Consolidated Statements of Operations. For further discussion on our restructuring plans, please refer to Note 4, “Restructuring.”

As a result of our first quarter of fiscal 2007 restructuring plan, we expect to reduce our annual infrastructure spending by approximately $22.2 million, of which approximately 8%, 24%, 44% and 24% will be reflected as a reduction in operations, research and development expense, sales and marketing expense, and general and administrative expense, respectively.

The increase in non-operating income for the three months ended April 1, 2007 over the comparable period in fiscal 2006 was primarily due to increased interest income of $37.5 million as a result of higher cash and investment balances partially related to the 1% Convertible Senior Notes due in fiscal 2013, partially offset by interest expense of $4.1 million related to coupon payments and amortization of expenses associated with the same convertible notes.

Provision for Income Taxes.


	Three months ended
	April 1, 2007			April 2, 2006
Provision for income taxes		72.6	%		54.0	%

We recorded tax provisions of $12.2 million and $41.3 million, or effective tax rates of 72.6% and 54.0%, for the three months ended April 1, 2007 and April 2, 2006, respectively. Our effective tax rate for the first quarter of fiscal 2007 differed from the statutory federal rate of 35.0% primarily due to the impact of state taxes, stock option compensation adjustments recorded under FAS 123(R), tax exempt interest income, research and development tax credits, the tax impact of acquisition-related intangible amortization taxed at rates lower than federal rates and certain other tax items recognized in the quarter, including a net adjustment of $3.4 million primarily related to the prior year.

We adopted FASB Interpretation No. 48, or FIN 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 at the beginning of fiscal 2007. As a result of the implementation of FIN 48 we recognized approximately a $1.0 million increase in the liability for unrecognized tax benefits, which was accounted for as a reduction to the January 1, 2007, balance of retained earnings. The total taxes payable of $44.0 million on uncertain tax positions is before federal tax benefit of state income taxes of $6.1 million. Of the net taxes payable of $37.9 million, $33.2 million would favorably impact the effective tax rate in future periods and $4.7 million would increase capital in excess of par value. We expect to recognize a $0.6 million tax benefit within the next 12 months as a result of the expiration of statutes of limitation. We will continue to recognize interest and/or penalties related to income taxes in income tax expense of which a $5.0 million accrual was outstanding as of the date of adoption and an additional $0.5 million was recorded in the three months ended April 1, 2007.

We are subject to U.S. federal income tax as well as income taxes in many state and foreign jurisdictions. The federal statute of limitations on assessment remains open for the tax years 2003 through 2006 and the statute of limitations in state jurisdictions remain open generally from tax years 2002 through 2006. The major foreign jurisdictions remain open for examination generally for tax years 2001 through 2006. We also had federal and state net operating loss carryforwards of approximately $89 million and $52 million before federal benefit, respectively, at December 31, 2006.

The tax benefit associated with the exercise of stock options for the three months ended April 1, 2007 and April 2, 2006 was credited to capital in excess of par value in the amount of $2.1 million and $41.9 million, respectively, when realized. On adoption of FIN 48, we recorded a $4.7 million reduction in capital in excess of par value.

Liquidity and Capital Resources

Our cash flows were as follows:


	Three months ended
	April 1, 2007			April 2, 2006
Net cash provided by operating activities	$	255,249		$	52,449
Net cash used for investing activities		(20,278	)		(51,851	)
Net cash used for financing activities		(4,950	)		87,970
Effect of changes in foreign currency exchange rates on cash		388			(61	)

Net increase (decrease) in cash and cash equivalents	$	230,409		$	88,507

Operating Activities. Operating activities generated $255.2 million of cash during the three months ended April 1, 2007 compared to $52.4 million of cash generated during the three months ended April 2, 2006. Non-cash increases over prior year resulted from increased depreciation related to our higher balance of equipment investments in the flash ventures, higher share-based compensation expenses related to overall headcount increases and our acquisition of msystems and reduced deferred taxes. In addition, reduction in accounts receivable were primarily due to collection on higher fourth quarter of fiscal 2006 receivable balances, increased price protection and promotional activities, and decreased shipments. Sources of cash from operating activities were primarily offset by lower deferred revenue due to decreased shipments and a reduction in income taxes payable.

Investing Activities. We used $20.3 million for investing activities during the three months ended April 1, 2007 compared to $51.9 million during the three months ended April 2, 2006. Cash used in investing activities were lower in the first quarter of fiscal 2007 compared to the comparable period in fiscal 2006 primarily due to lower investments in the flash ventures in the first quarter offset by increase use of cash related to purchased technology and increased cash provided by paydown of FlashVision’s note receivable.

Financing Activities. In the three months ended April 1, 2007, we used $5.0 million of cash from financing activities compared to the $88.0 million of cash received from financing activities during the three months ended April 2, 2006. Net cash from financing activities was lower in the first quarter of fiscal 2007 over the comparable period in fiscal 2006 primarily due to the use of cash from our share repurchase program initiated in the first quarter of fiscal 2007, lower tax benefits from share-based compensation and cash distributions to the minority interest holders of the TwinSys venture.

Liquid Assets. At April 1, 2007, we had cash, cash equivalents and short-term investments of $2.96 billion.

Short-Term Liquidity. As of April 1, 2007, our working capital balance was $3.45 billion. We do not expect any liquidity constraints in the next twelve months. We currently expect our total investments, loans, expenditures and guarantees over the next 12 months to be approximately $1.7 billion. Of this amount, we expect to loan, make investments or guarantee future operating leases for fab expansion of approximately $1.3 billion and expect to spend approximately $400 million on property and equipment, the majority of which is for assembly and test equipment. The additions for property and equipment includes assembly, test and engineering equipment, and equipment and building construction for our captive assembly and test manufacturing facility in Shanghai, China.

Long-Term Requirements. Depending on the demand for our products, we may decide to make additional investments, which could be substantial, in wafer fabrication foundry capacity and assembly and test manufacturing equipment to support our business in the future. We may also make equity investments in other companies or engage in merger or acquisition transactions. These additional investments may require us to raise additional financing, which could be difficult to obtain, and which if not obtained in satisfactory amounts may prevent us from funding the ventures with Toshiba, increasing our wafer supply, developing or enhancing our products, taking advantage of future opportunities, growing our business or responding to competitive pressures or unanticipated industry changes, any of which could harm our business.

Financing Arrangements. At April 1, 2007, we had $1.23 billion of aggregate principal amount in convertible notes outstanding, consisting of $1.15 billion in aggregate principal amount of our 1% Senior Notes due 2013 and $75 million in aggregate principal amount of our 1% Notes due 2035.

Also concurrent with the issuance of the 1% Convertible Senior Notes due 2013, we sold warrants to acquire shares of our common stock at an exercise price of $95.03 per share. As of April 1, 2007, the warrants have an expected life of approximately 6.25 years and expire in August 2013. At expiration, we may, at our option, elect to settle the warrants on a net share basis. As April 1, 2007, the warrants had not been exercised and remain outstanding. In addition, counterparties agreed to sell to us up to approximately 14.0 million shares of our common stock, which is the number of shares initially issuable upon conversion of the 1% Convertible Senior Notes due 2013 in full, at a price of $82.36 per share. The convertible bond hedge transaction will be settled in net shares and will terminate upon the earlier of the maturity date of the 1% Convertible Senior Notes due 2013 or the first day none of the 1% Convertible Senior Notes due 2013 remain outstanding due to conversion or otherwise. Settlement of the convertible bond hedge in net shares on the expiration date would result in us receiving net shares equivalent to the number of shares issuable by us upon conversion of the 1% Convertible Senior Notes due 2013. As of April 1, 2007, we have not purchased any shares under this convertible bond head agreement.

Toshiba Ventures. We are a 49.9% percent owner in FlashVision, Flash Partners and Flash Alliance, our business ventures with Toshiba to develop and manufacture NAND flash memory products. Toshiba owns 50.1% of each of these ventures. These NAND flash memory products are manufactured by Toshiba at Toshiba’s Yokkaichi, Japan operations using semiconductor manufacturing equipment owned or leased by FlashVision or Flash Partners or to be owned or leased by Flash Alliance. This equipment is funded or will be funded by investments in or loans to the ventures from us and Toshiba. FlashVision and Flash Partners purchase and Flash Alliance will purchase wafers from Toshiba at cost and then resell those wafers to us and Toshiba at cost plus a markup. We are contractually obligated to purchase our provided three month forecast of FlashVision’s, Flash Partners’ and, when operational, Flash Alliance’s NAND wafer supply, which generally equals 50 percent of such wafer supply. We cannot estimate the total amount of our wafer purchase commitment as of April 1, 2007 because our price is determined by reference to the future cost to produce the semiconductor wafers. In addition to the semiconductor assets owned or leased by FlashVision and Flash Partners, we directly own certain semiconductor manufacturing equipment in Toshiba’s 200-millimeter operations in Yokkaichi, Japan from which we receive 100% of the output. From time-to-time, we and Toshiba mutually approve increases in the wafer supply capacity of Flash Partners that may contractually obligate us to increase capital funding. We and Toshiba each pay the cost of our own design teams and 50% of the wafer processing and similar costs associated with this direct design and development of flash memory.

The cost of the wafers we purchase from FlashVision and Flash Partners and wafers we will purchase from Flash Alliance is recorded in inventory and ultimately cost of sales. FlashVision, Flash Partners and Flash Alliance are variable interest entities and we are not the primary beneficiary of these ventures because we are entitled to less than a majority of any residual gains and are obligated with respect to less than a majority of residual losses with respect to each venture. Accordingly, we account for our investments under the equity method and do not consolidate. Our share of the net income or loss of FlashVision, Flash Partners and Flash Alliance is included in our Condensed Consolidated Statements of Income as “Equity in income of business ventures.”

Under the FlashVision, Flash Partners and Flash Alliance agreements, we agreed to share in Toshiba’s costs associated with NAND product development and its common semiconductor research and development activities. We also fund direct research and development contribution based on a variable computation. As of April 1, 2007, we had accrued liabilities related to those expenses of $8.3 million. Our common research and development obligation related to FlashVision, Flash Partners and Flash Alliance is variable but capped at increasing fixed quarterly amounts through fiscal 2008. The common research and development participation agreement and the product development agreement are exhibits in our Annual Report on Form 10-K for the fiscal year ended December 31, 2006, and should be read carefully in their entirety for a more complete understanding of these arrangements.

For semiconductor fixed assets that are leased by FlashVision or Flash Partners, we and/or Toshiba have guaranteed, in whole or in part, the outstanding lease payments under each of those leases through various methods. These obligations are denominated in Japanese yen and are non-cancelable. Under the terms of the FlashVision lease, Toshiba guaranteed these commitments on behalf of FlashVision and we agreed to indemnify Toshiba for certain liabilities Toshiba incurs as a result of its guarantee of the FlashVision equipment lease arrangement. As of April 1, 2007, the maximum amount of our contingent indemnification obligation to Toshiba for their FlashVision lease guarantee, which reflects payments and any lease adjustments, was approximately 5.0 billion Japanese yen, or approximately $43 million based upon the exchange rate at April 1, 2007. Under the terms of the Flash Partners leases, we have guaranteed on an unsecured and several basis 50% of Flash Partners’ lease obligations under multiple master lease agreements entered into in fiscal 2004 through 2007. Our total Flash Partners lease obligation guarantees, net of lease payments as of April 1, 2007, were 107.4 billion Japanese yen, or approximately $915 million based upon the exchange rate at April 1, 2007. Toshiba has guaranteed the remaining 50% of Flash Partners’ lease obligations.

The capacity of Fab 4 at full expansion is expected to be greater than 150,000 wafers per month and the timeframe to reach full capacity is to be mutually agreed by the parties. To date, the parties have agreed to an expansion plan to 67,500 wafers per month for which the total investment in Fab 4 is currently estimated at approximately $2.0 billion through the end of fiscal 2008, of which our share is currently estimated to be approximately $1.0 billion. Initial NAND production at Fab 4 is currently scheduled for the end of fiscal 2007. For expansion beyond 67,500 wafers per month, it is expected that investments and output would continue to be shared 50/50 between us and Toshiba. We are committed to fund 49.9% of Flash Alliance’s costs to the extent that Flash Alliance’s revenues from wafer sales to us and Toshiba are insufficient to cover these costs. We expect to fund our portion of the investment through cash as well as other financing sources.

Contractual Obligations and Off Balance Sheet Arrangements

Our contractual obligations and off balance sheet arrangements at April 1, 2007, and the effect those obligations and arrangements are expected to have on our liquidity and cash flow over the next five years is presented in textual and tabular format in Note 10, “Commitments, Contingencies and Guarantees.”

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an on-going basis, we evaluate our estimates, including, among others, those related to customer programs and incentives, product returns, bad debts, inventories, investments, income taxes, warranty obligations, stock compensation, contingencies and litigation. We base our estimates on historical experience and on other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for our judgments about the carrying values of assets and liabilities when those values are not readily apparent from other sources. Estimates have historically approximated actual results. However, future results will differ from these estimates under different assumptions and conditions.

There were no significant changes to our critical accounting policies during the quarter ended April 1, 2007. For information about critical accounting policies, see the discussion of critical accounting policies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

Recent Accounting Pronouncements

SFAS No. 159. In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, or SFAS 159, Establishing the Fair Value Option for Financial Assets and Liabilities. The FASB has issued SFAS 159 to permit all entities to choose to elect, at specified election dates, to measure eligible financial instruments at fair value. An entity shall report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date, and recognize upfront costs and fees related to those items in earnings as incurred and not deferred. SFAS 159 applies to fiscal years beginning after November 15, 2007, or our 2008 fiscal year, with early adoption permitted for an entity that has also elected to apply the provisions of Statement of Financial Accounting Standards No. 157, Fair Value Measurements. An entity is prohibited from retrospectively applying SFAS 159, unless it chooses early adoption. SFAS 159 also applies to eligible items existing at November 15, 2007 (or early adoption date). We have not completed our analysis but do not expect the adoption of SFAS 159 to have a material effect on our financial condition.

EITF Issue No. 07-2. In the Emerging Issues Task Force, or Task Force, March 15, 2007 meeting, the Task Force opened EITF Issue No. 07-2, or EITF 07-2, Accounting for Convertible Debt Instruments That Require or Permit Partial Cash Settlement upon Conversion. The Task Force was asked to consider how a company should account for a convertible debt instrument that requires or permits partial cash settlement upon conversion if, at issuance, the embedded conversion option is not required to be separately accounted for as a derivative under Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities. The question is whether such instruments should be accounted for as convertible debt in accordance with Accounting Principles Board Opinion 14, or APB 14, Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants, and its related interpretations. Under APB 14, no proceeds would be allocated to the conversion feature of convertible debt. The scope of this issue would include Instrument C in EITF Issue No. 90-19, Convertible Bonds with Issuer Option to Settle for Cash upon Conversion, which is a debt instrument that, on conversion, must be satisfied with cash for the accreted value of the obligation and with either cash or stock for the conversion spread. As of April 1, 2007, the Task Force discussed the scope of this issue without reaching any conclusions. Although EITF 07-2 has not been issued, we have determined that if the Task Force determines that we should separately account for the liability and equity components of such instruments in a manner that reflects our economic interest cost, we would incur an additional interest expense of approximately $320 million to $370 million over the life of the debt, or approximately $70 million to $80 million in fiscal 2007.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to the disclosures in our Form 10-K for the fiscal year ended December 31, 2006.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this report (the “Evaluation Date”). Based upon the evaluation, our principal executive officer and principal financial officer concluded as of the Evaluation Date that our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the quarter ended April 1, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

On or about June 9, 2003, the Company received written notice from Infineon Technologies AG, or Infineon, that it believes the Company has infringed its U.S. Patent No. 5,726,601 (the ‘601 patent). On June 24, 2003, the Company filed a complaint against Infineon for a declaratory judgment of patent non-infringement and invalidity regarding the ‘601 patent in the United States District Court for the Northern District of California, captioned SanDisk Corporation v. Infineon Technologies AG, a German corporation, et al., Civil Case No. C 03 02931 BZ. On October 6, 2003, Infineon filed an answer and counterclaim: (a) denying that the Company is entitled to the declaration sought by the Company’s complaint; (b) requesting that the Company be adjudged to have infringed, actively induced and/or contributed to the infringement of the ‘601 patent and an additional patent, U.S. Patent No. 4,841,222 (the ‘222 patent). On August 12, 2004, Infineon filed an amended counterclaim for patent infringement alleging that the Company infringes U.S. Patent Nos. 6,026,002 (the ‘002 patent); 5,041,894 (the ‘894 patent); and 6,226,219 (the ‘219 patent), and omitting the ‘601 and ‘222 patents. On August 18, 2004, the Company filed an amended complaint against Infineon for a declaratory judgment of patent non-infringement and invalidity regarding the ‘002, ‘894, and ‘219 patents. On February 9, 2006, the Company filed a second amended complaint to include claims for declaratory judgment that the ‘002, ‘894 and ‘219 patents are unenforceable. On March 17, 2006, the Court granted a stipulation by the parties withdrawing all claims and counterclaims regarding the ‘002 patent. On February 20, 2007, the Court entered an order staying the case to facilitate settlement negotiations.

On October 15, 2004, the Company filed a complaint under Section 337 of the Tariff Act of 1930 (as amended) (Case No. 337-TA 526) titled, “In the matter of certain NAND flash memory circuits and products containing same” in the United States International Trade Commission (“ITC”), naming STMicroelectronics N.V. and STMicroelectronics, Inc. (collectively, “ST”) as respondents. In the complaint, the Company alleges that ST’s NAND flash memory infringes U.S. Patent No. 5,172,338 (the ‘338 patent), and seeks an order excluding ST’s products from importation into the United States. On November 15, 2004, the ITC instituted an investigation pursuant to 19 U.S.C. § 1337 against ST in response to the Company’s complaint. On December 9, 2004, ST filed a response to the complaint, denying that they infringe the ‘338 patent and alleging that the patent is invalid and/or unenforceable. A hearing was held from August 1-8, 2005. On October 19, 2005, the Administrative Law Judge issued an initial determination confirming the validity and enforceability of the Company’s ‘338 patent by rejecting ST’s claims that the patent was invalidated by prior art. The initial determination, however, found that ST’s NAND flash memory chips did not infringe the asserted claims of the ‘338 patent. On October 31, 2005, the Company filed a petition with the ITC to review and reverse the finding of non-infringement. Also, on October 31, 2005, ST filed a petition for review with the ITC to review and reverse the finding that the patent was valid and enforceable. On December 6, 2005, the ITC issued its decision. The ITC declined to review the finding of non-infringement, and, after reviewing the finding of validity, declined to take any position on the issue of validity. The Company appealed the ITC’s decision to the U.S. Court of Appeals for the Federal Circuit and the Federal Circuit affirmed the ITC’s decision on March 6, 2007.

On February 4, 2005, STMicro filed two complaints for patent infringement against the Company in the United States District Court for the Eastern District of Texas, captioned STMicroelectronics, Inc. v. SanDisk Corporation, Civil Case No. 4:05CV44 (the “‘44 Action”), and STMicroelectronics, Inc. v. SanDisk Corporation, Civil Case No. 4:05CV45 (the “‘45 Action”), respectively. The complaints seek damages and injunctions against certain SanDisk products. On April 22, 2005, the Company filed counterclaims on two patents against STMicroelectronics N.V. and STMicroelectronics, Inc. (collectively, “ST”) in the ‘45 Action. The counterclaims seek damages and injunctive relief against ST’s flash memory products. In the ‘44 Action, the District Court granted SanDisk’s motion for summary judgment of non-infringement on all accused products. ST has filed a motion to amend or correct the final judgment but no ruling has issued. On February 6, 2007, the District Court dismissed the ‘44 Action with prejudice, ordered that ST take nothing from the Company, and that costs be taxed against ST. In the ‘45 Action, the parties have filed motions for summary judgment regarding various aspects of the litigation. The magistrate judge has made recommendations on some but not all issues raised on summary judgment, but the trial judge has not made any final decisions on the magistrate judge’s recommendations. On March 26, 2007, the trial judge issued an order to stay the ‘45 Action for 90 days. The court will address the schedule for remaining activities in the case shortly before the end of the stay period.

On December 6, 2005, the Company filed a complaint for patent infringement in the United States District Court for the Northern District of California against STMicroelectronics, Inc. and STMicroelectronics, NV (collectively, “ST”) (Case No. C0505021 JF). In the suit, the Company seeks damages and injunctions against ST from making, selling, importing or using flash memory chips or products that infringe the Company’s U.S. Patent No. 5,991,517 (the “‘517 patent). The case is presently stayed, pending the termination of the ITC investigation instituted February 8, 2006, discussed below.

On January 10, 2006, the Company filed a complaint under Section 337 of the Tariff Act of 1930 (as amended) (Case No. 337-TA-560) titled, “In the matter of certain NOR and NAND flash memory devices and products containing same” in the ITC, naming ST as respondents. In the complaint, the Company alleges that: (i) ST’s NOR flash memory infringes the “338 patent; (ii) ST’s NAND flash memory infringes U.S. Patent No. 6,542,956 (the “‘956 patent”); and (iii) ST’s NOR flash memory and NAND flash memory infringe the ‘517 patent. The complaint seeks an order excluding ST’s NOR and NAND flash memory products from importation into the United States. The ITC instituted an investigation, based on the Company’s complaint, on February 8, 2006. On March 31, 2006, ST filed a motion for partial summary determination or termination of the investigation with respect to the ‘338 patent. On May 1, 2006, the Administrative Law Judge (“ALJ”) denied ST’s motion in an initial determination that is subject to review by the ITC. On May 17, 2006, SanDisk filed a motion to voluntarily terminate the investigation with respect to the ‘956 patent. On June 1, 2006, the ALJ issued an Initial Determination granting the Company’s motion. On August 15, 2006, the ALJ set December 4, 2006 as the date for the hearing, April 4, 2007 for the Initial Determination, and August 13, 2007 as the target date for completion of the investigation. On September 12, 2006, the Company filed a motion to voluntarily terminate the investigation with respect to claims 1, 2, and 4 of the ‘517 patent. On October 10, 2006, the ALJ issued an Initial Determination granting the Company’s motion with respect to claims 2 and 4 of the ‘517 patent. On September 25, 2006, ST filed motions for summary determination of non-infringement of the ‘338 patent with respect to its current products and non-infringement of the ‘338 and ‘517 patents with respect to prospective products and of lack of domestic industry with regard to the ‘338 patent. On the same date, SanDisk filed a motion for summary determination of the economic prong of the domestic industry requirement with regard to the ‘517 patent. On November 17, 2006, the ALJ granted SanDisk’s motion for summary determination of the economic prong of domestic industry, and denied ST’s motion for summary determination of lack of domestic industry with regard to the ‘338 patent. The ALJ denied one of ST’s motions for summary determination of noninfringement of the ‘338 patent. The ALJ granted ST’s motion for summary determination with respect to ST’s binary NOR products, which SanDisk was no longer accusing, and terminated the investigation with respect to certain prospective products. On November 28, 2006, the ALJ denied ST’s second motion for summary determination of non-infringement of the ‘338 patent. The ALJ then held an evidentiary hearing from December 1, 2006 through December 15, 2006. On January 16, 2007, the ALJ extended the due date of the initial determination due to June 1, 2007.

subject matter related to the patents asserted by Sisvel in the Netherlands. Specifically, Audio MPEG asserts U.S. Patent No. 5,214,678 (entitled “Digital transmission system using subband coding of a digital signal”), U.S. Patent No. 5,323,396 (entitled “Digital transmission system, transmitter and receiver for use in the transmission system”), U.S. Patent No. 5,539,829 (entitled “Subband coded digital transmission system using some composite signals”), and U.S. Patent No. 5,777,992 (entitled “Decoder for decoding and encoded digital signal and a receiver comprising the decoder”). As described above, in March 2007, the Company and Sisvel entered into a confidential agreement settling this matter and all related matters. Accordingly, all claims and counterclaims between the parties have been dismissed.

On February 20, 2007, Texas MP3 Technologies Ltd. filed suit against the Company, Samsung Electronics Co., Ltd., Samsung Electronics America, Inc. and Apple, Inc., Case No. 2:07-CV-52, in the Eastern District of Texas, Marshall Division, alleging patent infringement related to MP3 players. A trial date has not been set.

Item 1A. Risk Factors

The following description of the risk factors associated with our business includes any material changes to and supersedes the description of the risk factors associated with our business previously disclosed in Part 1, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

Our operating results may fluctuate significantly, which may adversely affect our operations and our stock price. Our quarterly and annual operating results have fluctuated significantly in the past and we expect that they will continue to fluctuate in the future. This fluctuation could result from a variety of factors, including, among others:

	•		average selling prices, net of promotions, declining at a faster rate than cost reductions for our products due to industry or SanDisk excess supply and competitive pricing pressures;

	•		addition of new competitors, expansion of supply from existing competitors and ourselves creating excess market supply, which could cause our average selling prices to decline faster than our costs decline;

	•		unpredictable or changing demand for our products, particularly demand for certain types or capacities of our products or demand for our products in certain markets or geographies;

	•		excess supply from captive sources due to output increasing faster than the growth in demand resulting in excess inventory;

	•		reduction in price elasticity of demand related to pricing changes for some of our markets and products;

	•		impairment of goodwill, business integration and other challenges related to our acquisition of msystems and Matrix;

	•		timing, volume and cost of wafer production from the FlashVision, Flash Partners and Flash Alliance ventures as impacted by Fab start-up delays and costs, technology transitions, yields or production interruptions;

	•		disruption in the manufacturing operations of suppliers, including suppliers of sole-sourced components;

	•		potential delays in the emergence of new markets and products for NAND flash memory and acceptance of our products in these markets;

	•		our license and royalty revenues may decline significantly in the future as our existing license agreements and key patents expire;

	•		timing of sell-through by our distributors and retail customers;

	•		increased purchases of flash memory products from our non-captive sources, which typically cost more than products from our captive sources;

	•		difficulty in forecasting and managing inventory levels, particularly due to noncancelable contractual obligations to purchase materials such as flash memory and controllers, and the need to build finished product in advance of customer purchase orders;

	•		insufficient supply from captive and non-captive sources or insufficient capacity from our test and assembly subcontractors to meet demand;

	•		errors or defects in our products caused by, among other things, errors or defects in the memory or controller components, including memory and non-memory components we procure from third-party suppliers;

	•		write-downs of our investments in fabrication capacity, equity investments and other assets;

	•		estimates used in calculating share-based compensation expense; and

	•		the other factors described under “Risk Factors” and elsewhere in this report.

Our average selling prices, net of promotions, may decline faster than cost reductions due to industry or SanDisk excess supply, competitive pricing pressures or strategic price reductions initiated by us or our competitors. The market for NAND flash products is competitive and characterized by rapid price declines. As an example, our average selling price per megabyte declined 62% in the first quarter of fiscal 2007 compared to the first quarter of fiscal 2006. Price declines may be influenced by, among other factors, supply in excess of demand, technology transitions, including adoption of MLC technology by other competitors, new technologies or other strategic actions by competitors to gain market share. If our technology transitions take longer or are more costly than anticipated to complete or our cost reductions fail to keep pace with the rate of price declines, our gross margins and operating results will be negatively impacted which could generate quarterly or annual net losses. In the past, price decreases have been more than offset by increased unit demand and demand for products with increased storage capacity. Recently, price declines have outpaced this increased demand resulting in lower gross margins. There can be no assurance that our current and future price reductions will result in sufficient demand for increased product capacity or unit sales, which could harm our margins and revenue growth.

Sales to a small number of customers represent a significant portion of our revenues and, if we were to lose one of our major licensees or customers or experience any material reduction in orders from any of our customers, our revenues and operating results would suffer. Sales to our top 10 customers and licensees accounted for more than 57%, 52% and 50%, of our total revenues during the first quarter of fiscal 2007 and fiscal years ended December 31, 2006 and January 1, 2006, respectively. No customer exceeded 10% of total revenues in any of these periods except Sony Ericsson Mobile Communications AB, or Sony Ericsson, and Samsung Electronics Co. Ltd., or Samsung, which accounted for 13% and 11% of our total revenues in the three months ended April 1, 2007 and Best Buy, Inc., which accounted for 11% in fiscal 2005. If we were to lose one of our major licensees or customers or experience any material reduction in orders from any of our customers or in sales of licensed products by our licensees, our revenues and operating results would suffer. Additionally, our license and royalty revenues may decline significantly in the future as our existing license agreements expire. Our sales are generally made from standard purchase orders rather than long-term contracts. Accordingly, our customers may generally terminate or reduce their purchases from us at any time without notice or penalty. In addition, the composition of our major customer base changes from year-to-year as we enter new markets, making our revenues from several customers somewhat less predictable from year-to-year.

Our business depends significantly upon sales of products in the highly competitive consumer market, a significant portion of which are made to retailers and through distributors, and if our distributors and retailers are not successful in this market, we could experience substantial product returns, which would negatively impact our business, financial condition and results of operations. A significant portion of our sales are made through retailers, either directly or through distributors. Sales through these channels typically include rights to return unsold inventory and protection against price declines. As a result, we do not recognize revenue until after the product has been sold through to the end user, in the case of sales to retailers, or to our distributors’ customers, in the case of sales to distributors. If our distributors and retailers are not successful, we could experience reduced sales as well as substantial product returns or price protection claims, which would harm our business, financial condition and results of operations. Availability of sell-through data varies throughout the retail channel, which makes it difficult for us to forecast retail product revenues. Our arrangements with our customers also provide them price protection against declines in our recommended selling prices, which has the effect of reducing our deferred revenue and eventually our revenue. Except in limited circumstances, we do not have exclusive relationships with our retailers or distributors, and therefore, must rely on them to effectively sell our products over those of our competitors.

Our revenue depends in part on the success of products sold by our OEM customers. An increasing portion of our sales are to OEMs, which either bundle or embed our flash memory products with their products, such as cameras or mobile phones. Our sales to these customers are dependent upon the OEMs choosing our products over those of our competitors and on the OEMs’ ability to create, introduce, market and sell their products successfully in their markets. Should our OEM customers be unsuccessful in selling their current or future products that include our products, or should they decide to discontinue utilizing our products, our results of operation and financial condition could be harmed. In addition, our OEM revenues could be less than in the past due to our decision in the fourth quarter of fiscal 2006 to de-emphasize the former msystems private label USB business and focus on our branded business and our decision with Toshiba to eliminate the TwinSys venture.

The continued growth of our business depends on the development of new markets and products for NAND flash memory and continued elasticity in our existing markets. Over the last several years, we derived the majority of our revenues from the digital camera market. This market continues to experience slower growth rates and continues to represent a declining percentage of our total revenue, and therefore, our growth will be increasingly dependent on the development of new markets, new applications and new products for NAND flash memory. For example, in fiscal 2006, our revenue from the digital camera market grew by only

2% over the prior year, and it is possible that our revenue from this market could decline in future years. Newer markets for flash memory include mobile phones, digital audio and video players and solid state drives. There can be no assurance that new markets and products will develop and grow fast enough, or that new markets will adopt NAND flash technologies in general or our products in particular, to enable us to continue our growth. There can be no assurance that the increase in average product capacity and unit demand in response to price reductions will continue to generate revenue growth for us as it has in the past. In the past, price decreases have been more than offset by increased unit demand and demand for products with increased storage capacity. Recently, price declines have outpaced this increased demand resulting in lower gross margins.

Our strategy of investing in captive manufacturing sources could harm us if our competitors are able to produce products more cheaply or if industry supply continues to exceed demand. We continue to secure captive sources of NAND and related devices through our significant investments in manufacturing capacity. We believe that by investing in captive sources of NAND we are able to develop and obtain supply at the lowest cost and access supply during periods of high demand. Our significant investments in manufacturing capacity require us to raise capital, including through the issuance of debt, obtain capital equipment leases and use available cash and investments which could otherwise be used for potentially more valuable corporate purposes. To the extent we secure manufacturing capacity and supply that is in excess of demand, or our cost is not competitive with other NAND suppliers, we may not achieve an adequate return on our significant investment and our revenues, gross margins and related market share may be negatively impacted. We may also incur increased inventory or impairment charges related to our captive manufacturing investments. In addition, if we finance these manufacturing investments with debt, our return may not be sufficient to finance the related debt payments or we may need to raise additional funding which could be difficult to obtain or may only be available at rates and or other terms that are unfavorable.

We continually seek to develop new applications, products, technologies and standards, which may not be widely adopted by consumers or, if adopted, may reduce demand by consumers for our older products. We continually seek to develop new applications, products and standards and enhance existing products and standards with higher memory capacities and other enhanced features. Any new applications, products, technologies, standards or enhancements we develop may not be commercially successful. The success of new product introductions is dependent on a number of factors, including market acceptance, our ability to manage risks associated with new products and production ramp issues. New applications, such as the adoption of flash memory cards in mobile phones, can take several years to develop. Early success in working with mobile phone manufacturers to add card slots to their mobile phones does not guarantee that consumers will adopt memory cards used for storing songs, images and other content in mobile phones. Our new products, such as Sansa^® View, Sansa^® Connect™, pre-recorded flash memory cards and solid state drives, may not gain market acceptance and we may not be successful in penetrating the new markets that we target. As we introduce new standards or technologies, such as TrustedFlash^™, it can take time for these new standards or technologies to be adopted, for consumers to accept and transition to these new standards or technologies and for significant sales to be generated from them, if this happens at all. Moreover, broad acceptance of new standards, technologies or products by consumers may reduce demand for our older products. If this decreased demand is not offset by increased demand for our other form factors or our new products, our results of operations could be harmed.

We face competition from numerous manufacturers and marketers of products using flash memory, as well as from manufacturers of new and alternative technologies, and if we cannot compete effectively, our results of operations and financial condition will suffer. Our competitors include many large companies that have greater access to advanced wafer manufacturing capacity and substantially greater financial, technical, marketing and other resources than we do, which allows them to produce flash memory chips in high volumes at low costs and to sell these flash memory chips themselves or to our flash card competitors at a low cost. Some of our competitors may sell their flash memory chips at or below their true manufacturing costs to gain market share and to cover their fixed costs. Such practices have been common in the DRAM industry during periods of excess supply, and have resulted in substantial losses in the DRAM industry. Our primary semiconductor competitors include Samsung, Toshiba, Hynix Semiconductor Inc., or Hynix, IM Flash Technologies, or IM Flash and STMicroelectronics, or STMicro. Samsung, in addition to ramping its overall NAND output, continues to ramp its MLC output. Hynix is aggressively ramping NAND output and IM Flash, and is expected to continue to produce significant NAND output in the future. All leading suppliers, including ourselves, have been substantially increasing NAND capacity, which is resulting in prices declining at a faster rate than cost reductions. We cannot predict when the balance between supply and demand will be achieved. In addition, current and future competitors produce or could produce alternative flash memory technologies that compete against our NAND flash memory technology which may reduce demand or accelerate price declines for NAND.

We also compete with flash memory card manufacturers and resellers. These companies purchase, or have a captive supply of, flash memory components and assemble memory cards. Our primary competitors currently include, among others, A-Data Technology Inc., Buffalo Technology Inc., FUJIFILM Corporation, Hagiwara Sys-Con Co., Ltd., Hama Corporation, Inc., I/O Data Device, Inc., Kingmax Digital, Inc., Kingston Technology Company, or Kingston, Eastman Kodak Company, Lexar Media, Inc., or Lexar, Matsushita Electric Industries, Ltd. which owns the Panasonic brands, Micron Technology, Inc., Netac Technology Co., Ltd., PNY Technologies, Inc., or PNY, RITEK Corporation, Samsung, Sony, Toshiba, Tradebrands International, and Transcend Information, Inc.

Some of our competitors have substantially greater resources than we do, have well recognized brand names or have the ability to operate their business on lower margins than we do. The success of our competitors may adversely affect our future sales revenues and may result in the loss of our key customers. For example, Toshiba and other manufacturers have recently increased their market share in the mobile market, including the microSD™ card, which has been a significant driver of our growth. In the digital audio market, we face competition from well established companies such as Apple and Microsoft. In the USB market we face competition from a large number of players including Kingston, Lexar, Memorex Products, Inc. and PNY, among others.

Furthermore, many companies are pursuing new or alternative technologies, such as phase-change technology, charge-trap flash and millipedes/probes, which may compete with flash memory. For example, two of our competitors are developing charge-trap flash technology, which if successful and if we are unable to scale our technology on an equivalent basis, could provide an advantage to these competitors.

These new or alternative technologies may provide smaller size, higher capacity, reduced cost, lower power consumption or other advantages. If we cannot compete effectively, our results of operations and financial condition will suffer.

We believe that our ability to compete successfully depends on a number of factors, including:

	•		price, quality and on-time delivery to our customers;

	•		product performance, availability and differentiation;

	•		success in developing new applications and new market segments;

	•		sufficient availability of supply;

	•		efficiency of production;

	•		timing of new product announcements or introductions by us, our customers and our competitors;

	•		the ability of our competitors to incorporate standards or develop formats which we do not offer;

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

	•		successful protection of intellectual property rights; and

	•		general market and economic conditions.

While we believe we are well-positioned to compete in the marketplace, there can be no assurance that we will be able to compete successfully in the future.

The semiconductor industry is subject to significant downturns that have harmed our business, financial condition and results of operations in the past and may do so in the future. The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence and price declines, evolving standards, short product life cycles and wide fluctuations in product supply and demand. The industry has experienced significant downturns, often in connection with, or in anticipation of, maturing product cycles of both semiconductor companies’ and their customers’ products

and declines in general economic conditions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated declines in selling prices. The flash memory industry is currently experiencing excess supply and experienced a rapid decline in prices in the first quarter of fiscal 2007. We have experienced these conditions in our business in the past and may experience such downturns in the future.

Our business and the markets we address are subject to significant fluctuations in supply and demand and our commitments to our ventures with Toshiba may result in periods of significant excess inventory. With the ramp to volume production at the Flash Partners’ 300-millimeter fab, Fab 3, in fiscal 2006, our captive memory supply increased substantially more than in either of the last two years. Our obligation to purchase 50% of the supply from FlashVision, Flash Partners and Flash Alliance, the ventures with Toshiba, could harm our business and results of operations if our committed supply exceeds demand for our products. The adverse effects could include, among other things, significant decreases in our product prices, significant excess, obsolete or lower of cost or market inventory write-downs and the impairment of our investments in the ventures with Toshiba. For example, in the first quarter of fiscal 2007, gross margins decreased to 24.8% in part due to inventory charges due to excess industry supply. In addition, over 95% of our NAND memory wafer purchases were from our ventures with Toshiba. These effects will be magnified once the Flash Alliance venture commences production, which we anticipate will occur in the fourth quarter of fiscal 2007. Any future excess supply could have a material adverse effect on our business, financial condition and results of operations.

We depend on third-party foundries for silicon supply and any disruption or shortage in our supply from these sources will reduce our revenues, earnings and gross margins. All of our flash memory card products require silicon supply for the memory and controller components. The substantial majority of our flash memory is currently supplied by our ventures with Toshiba and by Toshiba pursuant to our foundry agreement, and to a lesser extent by Samsung and Hynix. Any disruption in supply of flash memory from our captive or non-captive sources would harm our operating results. We intend to increase production at Fab 3, commence production at an additional 300-millimeter NAND wafer fabrication facility that is currently under construction, Fab 4, and continue to procure wafers from non-captive sources. In addition, these risks are magnified at Toshiba’s Yokkaichi, Japan operations, where the current ventures are operated, Fab 4 is being constructed, and Toshiba’s foundry capacity is located. Earthquakes and power outages have resulted in production line stoppage and loss of wafers in Yokkaichi and similar stoppages and losses may occur in the future. For example, in the first quarter of fiscal 2006, a brief power outage occurred at in Fab 3, and in April 2007, an earthquake occurred in Yokkaichi, Japan. Both incidences resulted in a loss of wafers and significant costs associated with bringing the Fab back on line. If the Fab 3 production ramp does not increase as anticipated, we fail to commence production at Fab 4 as planned, Fab 4 does not meet anticipated manufacturing output, or our non-captive sources fail to supply wafers in the amounts and at the times we expect, we may not have sufficient supply to meet demand and our operating results could be harmed. In addition, in March 2007, we signed a memorandum of understanding with Hynix that outlines a joint venture contemplated between the two companies which will manufacture memory components and sell NAND memory system solutions.

Currently, our controller wafers are only manufactured by Tower Semiconductor Ltd., or Tower, and United Microelectronics Corporation, or UMC, Taiwan Semiconductor Manufacturing Company Ltd., or TSMC, and Semiconductor Manufacturing International Corporation, or SMIC. The Tower fabrication facility, from which we source controller wafers, is facing financial challenges and is located in Israel, an area of political and military turmoil. Any disruption in the manufacturing operations of Tower or UMC would result in delivery delays, adversely affect our ability to make timely shipments of our products and harm our operating results until we could qualify an alternate source of supply for our controller wafers, which could take three or more quarters to complete. In times of significant growth in global demand for flash memory, demand from our customers may outstrip the supply of flash memory and controllers available to us from our current sources. If our silicon vendors are unable to satisfy our requirements on competitive terms or at all, we may lose potential sales and our business, financial condition and operating results may suffer. Any disruption or delay in supply from our silicon sources could significantly harm our business, financial condition and results of operations.

If actual manufacturing yields are lower than our expectations, this may result in increased costs and product shortages. The fabrication of our products requires wafers to be produced in a highly controlled and ultra clean environment. Semiconductor manufacturing yields and product reliability are a function of both design technology and manufacturing process technology and production delays may be caused by equipment malfunctions, fabrication facility accidents or human errors. Yield problems may not be identified or improved until an actual product is made and can be tested. As a result, yield problems may not be identified until the wafers are well into the production process. We have from time-to-time experienced yields that have adversely affected our business and results of operations. We have experienced adverse yields on more than one occasion when we have

transitioned to new generations of products. If actual yields are low, we will experience higher costs and reduced product supply, which could harm our business, financial condition and results of operations. For example, if the production ramp and/or yield of the 56-nanometer, 300-millimeter Flash Partners’ wafers do not increase as expected, we may not have enough supply to meet demand and our cost competitiveness, business, financial condition and results of operations will be harmed.

We depend on our third-party subcontractors and our business could be harmed if our subcontractors do not perform as planned. We rely on third-party subcontractors for our wafer testing, IC assembly, packaged testing, product assembly, product testing and order fulfillment. From time-to-time, our subcontractors have experienced difficulty in meeting our requirements. If we are unable to increase the capacity of our current subcontractors or qualify and engage additional subcontractors, we may not be able to meet demand for our products. We do not have long-term contracts with our existing subcontractors nor do we expect to have long-term contracts with any new subcontract suppliers. We do not have exclusive relationships with any of our subcontractors, and therefore, cannot guarantee that they will devote sufficient resources to manufacturing our products. We are not able to directly control product delivery schedules. Furthermore, we manufacture on a turnkey basis with some of our subcontract suppliers. In these arrangements, we do not have visibility and control of their inventories of purchased parts necessary to build our products or of the progress of our products through their assembly line. Any significant problems that occur at our subcontractors, or their failure to perform at the level we expect, could lead to product shortages or quality assurance problems, either of which would have adverse effects on our operating results.

We are constructing a captive assembly and test manufacturing facility in China. The Chinese government recently approved a 50-year lease by us of a piece of land to construct and equip a captive assembly and test manufacturing facility in the Zizhu Science-Based Park near Shanghai, China. Our anticipated expenditure for this project is approximately $170 million, of which approximately $150 million is expected to be paid in fiscal 2007. Any delays in the construction and equipping of the facility would harm our results of operations and financial condition. Once constructed, this facility is only intended to replace a portion of our test and assembly needs and therefore, we will continue to depend on our third-party subcontractors for a majority of our test and assembly needs.

In transitioning to new processes, products and silicon sources, we face production and market acceptance risks that may cause significant product delays, cost overruns or performance issues that could harm our business. Successive generations of our products have incorporated semiconductors with greater memory capacity per chip. The transition to new generations of products, such as the 56-nanometer 8 and 16 gigabit MLC chip, which we expect to begin shipping in volume in fiscal 2007, is highly complex and requires new controllers, new test procedures and modifications of numerous aspects of manufacturing, as well as extensive qualification of the new products by both us and our OEM customers. In addition, Flash Partners is currently ramping the 56-nanometer 8 gigabit MLC chip in the Yokkaichi, Japan 300-millimeter Fab and this transition is subject to yield, quality and output risk. There can be no assurance that this transition will occur on schedule or at the yields or costs that we anticipate. This technology transition is difficult and subject to significant risks in terms of schedule, yield and cost. If Flash Partners, or in the future, Flash Alliance, encounters difficulties in transitioning to new technologies, our cost per megabyte may not remain competitive with the costs achieved by other NAND flash memory producers. Any material delay in a development or qualification schedule could delay deliveries and adversely impact our operating results. We periodically have experienced significant delays in the development and volume production ramp-up of our products. Similar delays could occur in the future and could harm our business, financial condition and results of operations.

Our products may contain errors or defects, which could result in the rejection of our products, product recalls, damage to our reputation, lost revenues, diverted development resources and increased service costs and warranty claims and litigation. Our products are complex, must meet stringent user requirements, may contain errors or defects and the majority of our products are warrantied for one to five years. Errors or defects in our products may be caused by, among other things, errors or defects in the memory or controller components, including components we procure from non-captive sources such as the MLC products we procure from a third-party supplier. In addition, in the first quarter of fiscal 2007, over 95% of our NAND memory purchases were from our captive ventures with Toshiba and if the wafers contain errors or defects, our overall supply could be adversely affected. These factors could result in the rejection of our products, damage to our reputation, lost revenues, diverted development resources, increased customer service and support costs and warranty claims and litigation. We record an allowance for warranty and similar costs in connection with sales of our products, but actual warranty and similar costs may be significantly higher than our recorded estimate and result in an adverse effect on our results of operations and financial condition.

Our new products have from time-to-time been introduced with design and production errors at a rate higher than the error rate in our established products. We must estimate warranty and similar costs for new products without historical information and actual costs may significantly exceed our recorded estimates. Underestimation of our warranty and similar costs would have an adverse effect on our results of operations and financial condition.

We and Toshiba plan to continue to expand the wafer fabrication capacity of the Flash Partners business venture and have formed a new venture, Flash Alliance, for which we will make substantial capital investments and incur substantial start-up and tool relocation costs, which could adversely impact our operating results. We and Toshiba are making, and plan to continue to make, substantial investments in new capital assets to expand the wafer fabrication capacity of our Flash Partners business venture in Japan. We and Toshiba intend to invest $1.13 billion to continue expansion at Fab 3 to bring wafer capacity to 150,000 wafers per month by the end of fiscal 2007 and are cooperating in the construction of Fab 4 to produce NAND flash memory products for the parties under the Flash Alliance venture. We and Toshiba intend to invest 332 billion Japanese yen, or approximately $2.8 billion, based on the exchange rate at April 1, 2007, in the construction and equipping of Fab 4. Moreover, each time that we and Toshiba add substantial new wafer fabrication capacity, we will experience significant initial design and development and start-up costs as a result of the delay between the time of the investment and the time qualified products are manufactured and sold in volume quantities. For several quarters, we will incur initial design and development costs and start-up costs and pay our share of ongoing operating activities even if we do not achieve the planned output volume or utilize our full share of the expanded output, and these costs will impact our gross margins, results of operations and financial condition.

We have a contingent indemnification obligation and guarantee obligations related to the ventures with Toshiba. Toshiba has guaranteed FlashVision’s lease arrangement with third-party lessors. The total minimum remaining lease payments as of April 1, 2007 were 5.0 billion Japanese yen, or approximately $43 million based upon the exchange rate at April 1, 2007. If Toshiba makes payments under its guarantee, we have agreed to indemnify Toshiba for 49.9% of its costs, subject to certain limitations and exclusions.

In fiscal 2004 through fiscal 2007, Flash Partners entered into five separate equipment lease facilities totaling approximately 245.0 billion Japanese yen, or approximately $2.1 billion based upon the exchange rate at April 1, 2007, of which, as of April 1, 2007, 215.0 billion Japanese yen, or approximately $1.8 billion based upon the exchange rate at April 1, 2007, net of accumulated lease payments, had been drawn down. As of April 1, 2007, our cumulative guarantee under the equipment leases, net of cumulative lease payments, was approximately 107.4 billion Japanese yen, or approximately $915 million based on the exchange rate at April 1, 2007. These leases contain numerous default clauses which, if triggered, could cause us to repay the amounts due under our guarantees. If our corporate rating is significantly downgraded by any rating agency, it may impair the ability of our ventures with Toshiba to obtain future equipment lease financings on terms consistent with current leases and would cause a default under certain current leases, either of which could harm our business and financial condition.

We and Toshiba have also agreed to mutually contribute to, and indemnify each other, Flash Partners and Flash Alliance for environmental remediation costs or liability resulting from Flash Partners’ and Flash Alliance’s manufacturing operations in certain circumstances. In addition, we and Toshiba entered into a Patent Indemnification Agreement under which in many cases we will share in the expenses associated with the defense and cost of settlement associated with such claims. This agreement provides limited protection for us against third-party claims that NAND flash memory products manufactured and sold by Flash Partners or Flash Alliance infringe third-party patents.

None of the foregoing obligations are reflected as liabilities on our condensed consolidated balance sheets. If we have to perform our obligations under these agreements, our business will be harmed and our financial condition and results of operations will be adversely affected.

Seasonality in our business may result in our inability to accurately forecast our product purchase requirements. Sales of our products in the consumer electronics market are subject to seasonality. For example, sales have typically increased significantly in the fourth quarter of each year, sometimes followed by declines in the first quarter of the following year. This seasonality was particularly pronounced in the last two quarters during which we experienced a larger than average sequential increase in retail units sales in the fourth quarter of fiscal 2006, followed by a larger than average sequential decrease in retail unit sales in the first quarter of fiscal 2007. This seasonality may become even more pronounced if we increase the mix of our sales coming from consumer products such as our Sansa digital audio players. This seasonality increases the complexity of forecasting our business. If our forecasts are inaccurate, we can lose market share or procure excess inventory or inappropriately increase or decrease our operating expenses, any of which could harm our business, financial condition and results of operations. This seasonality also may lead to higher volatility in our stock price, the need for significant working capital investments in receivables and inventory and our need to build inventory levels in advance of our most active selling seasons.

From time-to-time, we overestimate our requirements and build excess inventory, and underestimate our requirements and have a shortage of supply, both of which harm our financial results. The majority of our products are sold into consumer markets, which are difficult to accurately forecast. Also, a substantial majority of our quarterly sales are from orders received and fulfilled in that quarter. Additionally, we depend upon timely reporting from our retail and distributor customers as to their inventory levels and sales of our products in order to forecast demand for our products. We have in the past significantly over-forecasted and under-forecasted actual demand for our products. The failure to accurately forecast demand for our products will result in lost sales or excess inventory both of which will have an adverse effect on our business, financial condition and results of operations. In addition, at times inventory may increase in anticipation of increased demand or as captive wafer capacity ramps. If demand does not materialize, we may be forced to write-down excess inventory which may harm our financial condition and results of operations.

Under conditions of tight flash memory supply, we may be unable to adequately increase our production volumes or secure sufficient supply in order to maintain our market share. If we are unable to maintain market share, our results of operations and financial condition could be harmed. Conversely, during periods of excess supply in the market for our flash memory products, we may lose market share to competitors who aggressively lower their prices and we may be forced to write-down inventory which is in excess of forecasted demand or must be sold below cost. If we lose market share due to price competition or we must write-down inventory, our results of operations and financial condition could be harmed.

Our ability to respond to changes in market conditions from our forecast is limited by our purchasing arrangements with our silicon sources. These arrangements generally provide that the first three months of our rolling six-month projected supply requirements are fixed and we may make only limited percentage changes in the second three months of the period covered by our supply requirement projections.

We are sole-sourced for a number of our critical components and the absence of a back-up supplier exposes our supply chain to unanticipated disruptions. We rely on our vendors, some of which are a sole source of supply, for many of our critical components. We do not have long-term supply agreements with most of these vendors. Our business, financial condition and operating results could be significantly harmed by delays or reductions in shipments if we are unable to develop alternative sources or obtain sufficient quantities of these components.

We are exposed to foreign currency risks. Our purchases of NAND flash memory from the Toshiba ventures and our investments in those ventures are denominated in Japanese yen. Our sales, however, are primarily denominated in U.S. dollars or other foreign currencies. Additionally, we expect over time to increase the percentage of our sales denominated in currencies other than the U.S. dollar. This exposes us to significant risk from foreign currency fluctuations. Management of these foreign exchange exposures and the foreign currency forward contracts used to mitigate these exposures is complex and if we do not successfully manage our foreign exchange exposures, our business, results of operations and financial condition could be harmed.

We may be unable to protect our intellectual property rights, which would harm our business, financial condition and results of operations. We rely on a combination of patents, trademarks, copyright and trade secret laws, confidentiality procedures and licensing arrangements to protect our intellectual property rights. In the past, we have been involved in significant and expensive disputes regarding our intellectual property rights and those of others, including claims that we may be infringing third-parties’ patents, trademarks and other intellectual property rights. We expect that we may be involved in similar disputes in the future. We cannot assure you that:

	•		any of our existing patents will not be invalidated;

	•		patents will be issued for any of our pending applications;

	•		any claims allowed from existing or pending patents will have sufficient scope or strength;

	•		our patents will be issued in the primary countries where our products are sold in order to protect our rights and potential commercial advantage; or

	•		any of our products or technologies do not infringe on the patents of other companies.

In addition, our competitors may be able to design their products around our patents and other proprietary rights. We also have patent cross-license agreements with several of our leading competitors. Under these agreements, we have enabled competitors to manufacture and sell products that incorporate technology covered by our patents. While we obtain license and royalty revenue or other consideration for these licenses, if we continue to license our patents to our competitors, competition may increase and may harm our business, financial condition and results of operations.

Several companies have recently entered or announced their intentions to enter the flash memory market, and we believe these companies may require a license from us. Enforcement of our rights may require litigation. If we bring a patent infringement action and are not successful, our competitors would be able to use similar technology to compete with us. Moreover, the defendant in such an action may successfully countersue us for infringement of their patent or assert a counterclaim that our patents are invalid or unenforceable. If we did not prevail as a defendant in patent infringement case, we could be required to pay substantial damages, cease the manufacture, use and sale of infringing products, expend significant resources to develop non-infringing technology, discontinue the use of specific processes or obtain licenses to the infringing technology.

We may be unable to license intellectual property to or from third-parties as needed, or renew existing licenses, which could expose us to liability for damages, reduce our royalty revenues, increase our costs or limit or prohibit us from selling products. If we incorporate third-party technology into our products or if we are found to infringe others’ intellectual property, we could be required to license intellectual property from a third party. We may also need to license some of our intellectual property to others in order to enable us to obtain important cross-licenses to third-party patents. We cannot be certain that licenses will be offered when we need them, or that the terms offered will be acceptable, or that these licenses will help our business. If we do obtain licenses from third-parties, we may be required to pay license fees or royalty payments. In addition, if we are unable to obtain a license that is necessary to the manufacture of our products, we could be required to suspend the manufacture of products or stop our product suppliers from using processes that may infringe the rights of third-parties. We may not be successful in redesigning our products, the necessary licenses may not be available under reasonable terms, our existing licensees may not renew their licenses upon expiration and we may not be successful in signing new licensees in the future.

We are currently and may in the future be involved in litigation, including litigation regarding our intellectual property rights or those of third parties, which may be costly, may divert the efforts of our key personnel and could result in adverse court rulings, which could materially harm our business. We are involved in a number of lawsuits, including among others, several cases involving our patents and the patents of third-parties. We are the plaintiff in some of these actions and the defendant in other of these actions. Some of the actions could seek injunctions against the sale of our products and/or substantial monetary damages, which if granted or awarded, could have a material adverse effect on our business, financial condition and results of operations.

Litigation is subject to inherent risks and uncertainties that may cause actual results to differ materially from our expectations. Factors that could cause litigation results to differ include, but are not limited to, the discovery of previously unknown facts, changes in the law or in the interpretation of laws, and uncertainties associated with the judicial decision-making process. If we receive an adverse judgment in any litigation, we could be required to pay substantial damages and/or cease the manufacture, use and sale of products. Litigation, including intellectual property litigation, can be complex, can extend for a protracted period of time, and can be very expensive. Litigation initiated by us could also result in counter-claims against us, which could increase the costs associated with the litigation and result in our payment of damages or other judgments against us. In addition, litigation may divert the efforts and attention of some of our key personnel.

We have been, and expect to continue to be, subject to claims and legal proceedings regarding alleged infringement by us of the patents, trademarks and other intellectual property rights of third-parties. From time-to-time we have sued, and may in the future sue, third-parties in order to protect our intellectual property rights. Parties that we have sued and that we may sue for patent infringement may countersue us for infringing their patents. If we are held to infringe the intellectual property of others, we may need to spend significant resources to develop non-infringing technology or obtain licenses from third-parties, but we may not be able to develop such technology or acquire such licenses on terms acceptable to us or at all. We may also be required to pay significant damages and/or discontinue the use of certain manufacturing or design processes. In addition, we or our suppliers could be enjoined from selling some or all of our respective products in one or more geographic locations. If we or our suppliers are enjoined from selling any of our respective products or if we are required to develop new technologies or pay significant monetary damages or are required to make substantial royalty payments, our business would be harmed.

Moreover, from time-to-time we agree to indemnify certain of our suppliers and customers for alleged patent infringement. The scope of such indemnity varies but generally includes indemnification for direct and consequential damages and expenses, including attorneys’ fees. We may from time-to-time be engaged in litigation as a result of these indemnification obligations. Third-party claims for patent infringement are excluded from coverage under our insurance policies. A future obligation to indemnify our customers or suppliers may have a material adverse effect on our business, financial condition and results of operations. For additional information concerning legal proceedings, see Part 2, Item 1, “Legal Proceedings.”

Because of our international business and operations, we must comply with numerous international laws and regulations, and we are vulnerable to political instability, currency fluctuations and other risks related to international operations. Currently, all of our products are produced overseas in China, Israel, Japan, South Korea and Taiwan. We are, therefore, affected by the political, economic, labor, environmental, public health and military conditions in these countries.

Specifically, China does not currently have a comprehensive and highly developed legal system, particularly with respect to the protection of intellectual property rights. These results, among other things, in the prevalence of counterfeit goods in China. The enforcement of existing and future laws and contracts remains uncertain, and the implementation and interpretation of such laws may be inconsistent. Such inconsistency could lead to piracy and degradation of our intellectual property protection. Although we have increased our efforts to prevent counterfeit products from entering the market, those efforts may not be successful. Our results of operations and financial condition could be harmed by the sale of counterfeit products.

Our international business activities could also be limited or disrupted by any of the following factors:

	•		the need to comply with foreign government regulation;

	•		changes in diplomatic and trade relationships;

	•		reduced sales to our customers or interruption to our manufacturing processes in the Pacific Rim that may arise from regional issues in Asia;

	•		imposition of regulatory requirements, tariffs, import and export restrictions and other barriers and restrictions;

	•		duties and/or fees related to customs entries for our products, which are all manufactured offshore;

	•		longer payment cycles and greater difficulty in accounts receivable collection;

	•		adverse tax rules and regulations;

	•		weak protection of our intellectual property rights; and

	•		delays in product shipments due to local customs restrictions.

Tower Semiconductor’s Financial Situation is Challenging. Tower supplies a significant portion of our controller wafers from its Fab 2 facility and is currently a sole source of supply for some of our controllers. Tower’s Fab 2 is operational and in the process of expanding capacity and our ability to continue to obtain sufficient supply on a cost-effective basis may be dependent upon completion of this capacity expansion. Tower’s continued expansion of Fab 2 requires sufficient funds to operate in the short-term and raising the funds required to implement the current ramp-up plan. If Tower fails to comply with the financial ratios and covenants contained in the amended credit facility agreement with its banks, fails to attract additional customers, fails to operate its Fab 2 facility in a cost-effective manner, fails to secure additional financing, fails to meet the conditions to receive government grants and tax benefits approved for Fab 2, or fails to obtain the approval of the Israeli Investment Center for a new expansion program, Tower’s continued operations could be at risk. If this occurs, we will be forced to source our controllers from another supplier and our business, financial condition and results of operations may be harmed. Specifically, our ability to supply a number of products would be disrupted until we were able to transition manufacturing and qualify a new foundry with respect to controllers that are currently sole sourced at Tower, which could take three or more quarters to complete.

We have recognized cumulative losses of approximately $54.1 million as a result of the other-than-temporary decline in the value of our investment in Tower ordinary shares, $12.2 million as a result of the impairment in value on our prepaid wafer credits and $1.3 million of losses on our warrant to purchase Tower ordinary shares as of April 1, 2007. We are subject to certain restrictions on the transfer of our approximately 12.8 million Tower ordinary shares including certain rights of first refusal, and through January 2008, have agreed to maintain minimum shareholdings. It is possible that we will record further write-downs of our investment, which was carried on our condensed consolidated balance sheet at $21.4 million at April 1, 2007, which would harm our results of operations and financial condition.

Our stock price has been, and may continue to be, volatile, which could result in investors losing all or part of their investments. The market price of our stock has fluctuated significantly in the past and may continue to fluctuate in the future. We believe that such fluctuations will continue as a result of many factors, including future announcements concerning us, our competitors or our principal customers regarding financial results or expectations, technological innovations, industry supply dynamics, new product introductions, governmental regulations, the commencement or results of litigation or changes in earnings estimates by analysts. In addition, in recent years the stock market has experienced significant price and volume fluctuations and the market prices of the securities of high technology and semiconductor companies have been especially volatile, often for reasons outside the control of the particular companies. These fluctuations as well as general economic, political and market conditions may have an adverse affect on the market price of our common stock as well as the price of our outstanding convertible notes and could impact the likelihood of those notes being converted into our common stock, which would cause further dilution to our stockholders.

We may make acquisitions that are dilutive to existing stockholders, result in unanticipated accounting charges or otherwise adversely affect our results of operations, and result in difficulties in assimilating and integrating the operations, personnel, technologies, products and information systems of acquired companies or businesses. We continually evaluate and explore strategic opportunities as they arise, including business combinations, strategic partnerships, collaborations, capital investments and the purchase, licensing or sale of assets. If we issue equity securities in connection with an acquisition, the issuance may be dilutive to our existing stockholders. Alternatively, acquisitions made entirely or partially for cash would reduce our cash reserves.

Acquisitions may require significant capital infusions, typically entail many risks and could result in difficulties in assimilating and integrating the operations, personnel, technologies, products and information systems of acquired companies. We may experience delays in the timing and successful integration of acquired technologies and product development through volume production, unanticipated costs and expenditures, changing relationships with customers, suppliers and strategic partners, or contractual, intellectual property or employment issues. In addition, key personnel of an acquired company may decide not to work for us. The acquisition of another company or its products and technologies may also result in our entering into a geographic or business market in which we have little or no prior experience. These challenges could disrupt our ongoing business, distract our management and employees, harm our reputation, subject us to an increased risk of intellectual property and other litigation and increase our expenses. These challenges are magnified as the size of the acquisition increases, and we cannot assure you that we will realize the intended benefits of any acquisition. Acquisitions may require large one-time charges and can result in increased debt or contingent liabilities, adverse tax consequences, substantial depreciation or deferred compensation charges, the amortization of identifiable purchased intangible assets or impairment of goodwill, any of which could have a material adverse effect on our business, financial condition or results of operations.

Mergers and acquisitions of high-technology companies are inherently risky and subject to many factors outside of our control, and no assurance can be given that our previous or future acquisitions will be successful and will not materially adversely affect our business, operating results, or financial condition. Failure to manage and successfully integrate acquisitions could materially harm our business and operating results. Even when an acquired company has already developed and marketed products, there can be no assurance that such products will be successful after the closing, will not cannibalize sales of our existing products, that product enhancements will be made in a timely fashion or that pre-acquisition due diligence will have identified all possible issues that might arise with respect to such company.

Our success depends on our key personnel, including our executive officers, the loss of whom could disrupt our business. Our success greatly depends on the continued contributions of our senior management and other key research and development, sales, marketing and operations personnel, including Dr. Eli Harari, our founder, chairman and chief executive officer. We do not have employment agreements with any of our executive officers and they are free to terminate their employment with us at any time. Our success will also depend on our ability to recruit additional highly skilled personnel. We may not be successful in hiring or retaining key personnel.

Terrorist attacks, war, threats of war and government responses thereto may negatively impact our operations, revenues, costs and stock price. Terrorist attacks, U.S. military responses to these attacks, war, threats of war and any corresponding decline in consumer confidence could have a negative impact on consumer retail demand, which is the largest channel for our products. Any of these events may disrupt our operations or those of our customers and suppliers and may affect the availability of materials needed to manufacture our products or the means to transport those materials to manufacturing facilities and finished products to customers. Any of these events could also increase volatility in the U.S. and world financial markets, which could harm our stock price and may limit the capital resources available to us and our customers or suppliers or adversely affect consumer confidence. We have substantial operations in Israel including a development center in Northern Israel, near the border with Lebanon, areas that have recently experienced significant violence and political unrest. Tower which supplies a significant portion of our controller wafers is also located in Israel. Continued turmoil and unrest in Israel or the Middle East could cause delays in the development or production of our products. This could harm our business and results of operations.

Natural disasters or epidemics in the countries in which we or our suppliers or subcontractors operate could negatively impact our operations. Our operations, including those of our suppliers and subcontractors, are concentrated in Milpitas, California; Yokkaichi, Japan; Hsinchu and Taichung, Taiwan; and Dongguan, Shanghai and Shenzen, China. In the past, these areas have been affected by natural disasters such as earthquakes, tsunamis and typhoons, and some areas have been affected by epidemics, such as avian flu. If a natural disaster or epidemic were to occur in one or more of these areas, our operations could be significantly impaired and our business may be harmed. This is magnified by the fact that we do not have insurance for most natural disasters, including earthquakes. This could harm our business and results of operations.

To manage our growth, we may need to improve our systems, controls, processes and procedures. We have experienced and may continue to experience rapid growth, which has placed, and could continue to place a significant strain on our managerial, financial and operations resources and personnel. Our number of employees, including management-level employees, has increased significantly, due to our acquisition of msystems. As a result of the acquisition, we have recently reorganized our corporation into several business units to increase focus on market penetration, new product innovation and profitability. The reorganization requires re-engineering of many processes and systems within our company. We must continue to improve our operational, accounting and financial systems and managerial controls and procedures, including fraud procedures, and we will need to continue to expand, as well as, train and manage our workforce. If we do not manage our growth effectively or adapt our systems, processes and procedures to the evolving business and organization, our business and results of operations could be harmed.

We may need to raise additional financing, which could be difficult to obtain, and which if not obtained in satisfactory amounts may prevent us from funding the ventures with Toshiba, increasing our wafer supply, developing or enhancing our products, taking advantage of future opportunities, growing our business or responding to competitive pressures or unanticipated industry changes, any of which could harm our business. We currently believe that we have sufficient cash resources to fund our operations as well as our investments in the ventures with Toshiba for at least the next twelve months; however, we may in the future raise additional funds, including funds to meet our obligations with respect to Flash Partners and Flash Alliance, and we cannot be certain that we will be able to obtain additional financing on favorable terms, if at all. From time-to-time, we may decide to raise additional funds through public or private debt, equity or lease financings. If we issue additional equity securities, our stockholders will experience dilution and the new equity securities may have rights, preferences or privileges senior to those of existing holders of common stock. If we raise funds through debt or lease financing, we will have to pay interest and may be subject to restrictive covenants, which could harm our business. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products, fulfill our obligations to Flash Partners and Flash Alliance, take advantage of future opportunities, grow our business or respond to competitive pressures or unanticipated industry changes, any of which could have a negative impact on our business.

Anti-takeover provisions in our charter documents, stockholder rights plan and in Delaware law could discourage or delay a change in control and, as a result, negatively impact our stockholders. We have taken a number of actions that could have the effect of discouraging a takeover attempt. For example, we have a stockholders’ rights plan that would cause substantial dilution to a stockholder, and substantially increase the cost paid by a stockholder, who attempts to acquire us on terms not approved by our board of directors. This could discourage an acquisition of us. In addition, our certificate of incorporation grants our board of directors the authority to fix the rights, preferences and privileges of and issue up to 4,000,000 shares of preferred stock without stockholder action (2,000,000 of which have already been reserved under our stockholder rights plan). Issuing preferred stock could have the effect of making it more difficult and less attractive for a third party to acquire a majority of our outstanding voting stock. Preferred stock may also have other rights, including economic rights senior to our common stock that could have a material adverse effect on the market value of our common stock. In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. This section provides that a corporation may not engage in any business combination with any interested stockholder during the three-year period following the time that a stockholder became an interested stockholder. This provision could have the effect of delaying or discouraging a change of control of SanDisk.

Unanticipated changes in our tax provisions or exposure to additional income tax liabilities could affect our profitability. We are subject to income taxes in the United States and numerous foreign jurisdictions. Our tax liabilities are affected by the amounts we charge for inventory, services, licenses, funding and other items in intercompany transactions. We are subject to ongoing tax audits in various jurisdictions. Tax authorities may disagree with our intercompany charges or other matters and assess additional taxes. We regularly assess the likely outcomes of these audits in order to determine the appropriateness of our tax provision. However, there can be no assurance that we will accurately predict the outcomes of these audits, and the actual outcomes of these audits could have a material impact on our net income or financial condition. In addition, our effective tax rate in the future could be adversely affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in tax laws and the discovery of new information in the course of our tax return preparation process. In particular, the carrying value of deferred tax assets, which are predominantly in the United States, is dependent on our ability to generate future taxable income in the United States. Any of these changes could affect our profitability. Declining product margins can cause reduced profits in our manufacturing entities which are primarily located in relatively low tax rate jurisdictions. Continued product margin declines could have a material adverse impact on our effective tax rate. Furthermore, our tax provisions could be adversely affected as a result of any further interpretative accounting guidance related to accounting for uncertain tax provisions.

We may be subject to risks associated with environmental regulations. Production and marketing of products in certain states and countries may subject us to environmental and other regulations including, in some instances, the responsibility for environmentally safe disposal or recycling. Such laws and regulations have recently been passed in several jurisdictions in which we operate, including Japan and certain states within the U.S. Although we do not anticipate any material adverse effects in the future based on the nature of its operations and the thrust of such laws, there is no assurance such existing laws or future laws will not have a material adverse effect on our financial condition, liquidity, or results of operations.

Changes in securities laws and regulations have increased our costs; further, in the event we are unable to satisfy regulatory requirements relating to internal control, or if our internal control over financial reporting is not effective, our business could suffer. The Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley, that became law in July 2002 required changes in our corporate governance, public disclosure and compliance practices. The number of rules and regulations applicable to us has increased and will continue to increase our legal and financial compliance costs, and has made some activities more difficult, such as approving new or amendments to our option plans. In addition, we have incurred and expect to continue to incur significant costs in connection with compliance with Section 404 of Sarbanes-Oxley regarding internal control over financial reporting. In 2007, we will continue to incur additional costs integrating msystems into our internal control systems and procedures. These laws and regulations and perceived increased risk of liability could make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee, and qualified executive officers. We cannot estimate the timing or magnitude of additional costs we may incur as a result.

In connection with our certification process under Section 404 of Sarbanes-Oxley, we have identified in the past and will from time-to-time identify deficiencies in our internal control over financial reporting. We cannot assure you that individually or in the aggregate these deficiencies would not be deemed to be a material weakness. Furthermore, we may not be able to implement enhancements on a timely basis, including any enhancements necessary to integrate msystems operations, in order to prevent a failure of our internal controls or enable us to furnish future unqualified certifications. A material weakness or deficiency in internal control over financial reporting could materially impact our reported financial results and the market price of our stock could significantly decline. Additionally, adverse publicity related to the disclosure of a material weakness or deficiency in internal controls could have a negative impact on our reputation, business and stock price. Any internal control or procedure, no matter how well designed and operated, can only provide reasonable assurance of achieving desired control objectives and cannot prevent intentional misconduct or fraud.

Our debt service obligations may adversely affect our cash flow. While the 1% Notes due 2013 and the 1% Notes due 2035, are outstanding, we are obligated to pay to the holders thereof approximately $12.3 million per year in interest. If we issue other debt securities in the future, our debt service obligations will increase. If we are unable to generate sufficient cash to meet these obligations and must instead use our existing cash or investments, we may have to reduce, curtail or terminate other activities of our business. We intend to fulfill our debt service obligations from cash generated by our operations, if any, and from our existing cash and investments. We may also in the future enter into other financial instruments that could increase our debt service obligations.

Our indebtedness could have significant negative consequences. For example, it could:

	•		increase our vulnerability to general adverse economic and industry conditions;

	•		limit our ability to obtain additional financing;

	•		require the dedication of a substantial portion of any cash flow from operations to the payment of principal of, and interest on, our indebtedness, thereby reducing the availability of such cash flow to fund our growth strategy, working capital, capital expenditures and other general corporate purposes;

	•		limit our flexibility in planning for, or reacting to, changes in our business and our industry; and

	•		place us at a competitive disadvantage relative to our competitors with less debt.

The accounting method for convertible debt securities with net share settlement, like our 1% notes due 2013 (“the notes”), may be subject to change. For the purpose of calculating diluted earnings per share, a convertible debt security providing for net share settlement of the conversion value and meeting specified requirements under Emerging Issues Task Force, or EITF, Issue No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock, is accounted for interest expense purposes similarly to non-convertible debt, with the stated coupon constituting interest expense and any shares issuable upon conversion of the security being accounted for under the treasury stock method. The effect of the treasury stock method is that the shares potentially issuable upon conversion of the notes are not included in the calculation of our earnings per share except to the extent that the conversion value of the notes exceeds their principal amount, in which event the number of shares of our common stock necessary to settle the conversion are treated as having been issued for earnings per share purposes. The EITF is reviewing, among other things, the accounting method for net share settled convertible securities. A subcommittee of the EITF is considering a proposed method for accounting for net share settled convertible securities under which the debt and equity components of the security would be bifurcated and accounted for separately. We cannot predict the outcome of the EITF deliberations or any other changes in GAAP that may be made affecting accounting for convertible debt securities. Any change in the accounting method for convertible debt securities could have an adverse impact on our past or future financial results. These impacts could adversely affect the trading price of our common stock and in turn negatively impact the trading price of the notes.

We have significant financial obligations related to our ventures with Toshiba, which could impact our ability to comply with our obligations under our 1% Notes due 2013 and our 1% Notes due 2035. We have entered into agreements to guarantee, indemnify or provide financial support with respect to lease and certain other obligations of our ventures with Toshiba in which we have a 49.9% ownership interest. In addition, we may enter into future agreements to increase manufacturing capacity, including the further expansion of Fab 3 and the start-up and expansion of Fab 4. As of April 1, 2007, we had unfunded commitments of approximately $1.55 billion to fund our various obligations under the Flash Partners and Flash Alliance ventures with Toshiba. As of April 1, 2007, we had indemnification and guarantee obligations for these ventures of approximately $958 million. Due to these and our other commitments, we may not have sufficient funds to make payments under or repurchase the notes.

The net share settlement feature of the 1% Notes due 2013 may have adverse consequences. The 1% Notes due 2013 are subject to net share settlement, which means that we will satisfy our conversion obligation to holders by paying cash in settlement of the lesser of the principal amount and the conversion value of the 1% Notes due 2013 and by delivering shares of our common stock in settlement of any and all conversion obligations in excess of the daily conversion values.

Our failure to convert the 1% Notes due 2013 into cash or a combination of cash and common stock upon exercise of a holder’s conversion right in accordance with the provisions of the indenture would constitute a default under the indenture. We may not have the financial resources or be able to arrange for financing to pay such principal amount in connection with the surrender of the 1% Notes due 2013 for conversion. While we currently only have debt related to the 1% Notes due 2013 and the 1% Notes due 2035 and we do not have other agreements that would restrict our ability to pay the principal amount of the 1% Notes due 2013 in cash, we may enter into such an agreement in the future, which may limit or prohibit our ability to make any such payment. In addition, a default under the indenture could lead to a default under existing and future agreements governing our indebtedness. If, due to a default, the repayment of related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay such indebtedness and amounts owing in respect of the conversion of any 1% Notes due 2013.

The convertible note hedge transactions and the warrant option transactions may affect the value of the notes and our common stock. We have entered into convertible note hedge transactions with Morgan Stanley & Co. International Limited and Goldman, Sachs & Co., or the dealers. These transactions are expected to reduce the potential dilution upon conversion of the notes. We used approximately $67.3 million of the net proceeds of funds received from the 1% Notes due 2013 to pay the net cost of the convertible note hedge in excess of the warrant transactions. These transactions were accounted for as an adjustment to our stockholders’ equity. In connection with hedging these transactions, the dealers or their affiliates:

	•		have entered into various over-the-counter cash-settled derivative transactions with respect to our common stock, concurrently with, and shortly after, the pricing of the notes; and

	•		may enter into, or may unwind, various over-the-counter derivatives and/or purchase or sell our common stock in secondary market transactions following the pricing of the notes, including during any observation period related to a conversion of notes.

The dealers or their affiliates are likely to modify their hedge positions from time-to-time prior to conversion or maturity of the notes by purchasing and selling shares of our common stock, other of our securities or other instruments they may wish to use in connection with such hedging. In particular, such hedging modification may occur during any observation period for a conversion of the 1% Notes due 2013, which may have a negative effect on the value of the consideration received in relation to the conversion of those notes. In addition, we intend to exercise options we hold under the convertible note hedge transactions whenever notes are converted. To unwind their hedge positions with respect to those exercised options, the dealers or their affiliates expect to sell shares of our common stock in secondary market transactions or unwind various over-the-counter derivative transactions with respect to our common stock during the observation period, if any, for the converted notes.

The effect, if any, of any of these transactions and activities on the market price of our common stock or the 1% Notes due 2013 will depend in part on market conditions and cannot be ascertained at this time, but any of these activities could adversely affect the value of our common stock and the value of the 1% Notes due 2013 and, as a result, the amount of cash and the number of shares of common stock, if any, holders will receive upon the conversion of the notes.

There are numerous risks associated with our acquisition of msystems Ltd. Achieving the expected benefits of the acquisition will depend on the timely and efficient integration of our and msystems’ technology, product lines, operations, business culture and personnel. This will be particularly challenging due to the fact that the majority of the msystems operations are in Israel and we are headquartered in California. The integration may not be completed as quickly as expected, and if we fail to effectively integrate the companies or the integration takes longer than expected, we may not achieve the expected benefits of the merger. The challenges involved in this integration include, among others:

	•		retaining the customers and sales distribution channels of both companies;

	•		maintaining employee morale and retaining key employees;

	•		retaining key sources of supply;

	•		incorporating msystems’ technology and products into our business and future product lines;

	•		integrating msystems’ sales force into our worldwide product sales network;

	•		demonstrating to msystems’ customers that the merger will not result in adverse changes in pricing, customer service standards or product support;

	•		coordinating research and development activities to enhance introduction of new products and technologies;

	•		integrating msystems’ internal control over financial reporting with our internal control over financial reporting;

	•		migrating both companies to a common enterprise resource planning information system to integrate all operations, sales and administrative activities for the combined companies in a timely and cost effective way;

	•		integrating msystems’ international operations with ours;

	•		integrating the business cultures of both companies; and

	•		ensuring there are no delays in releasing new products to market.

This integration effort is international in scope, complex, time consuming and expensive, and may disrupt our respective businesses or result in the loss of customers or key employees or the diversion of the attention of management. Neither msystems nor we have experience in integrating businesses and operations of this magnitude and scope. Integration is particularly difficult because certain key members of msystems’ senior management are no longer with the combined company. In addition, the integration process may strain our financial and managerial controls and reporting systems and procedures. This may result in the diversion of management and financial resources from our core business objectives. There can be no assurance that we and msystems will successfully integrate our respective businesses or that we will realize the anticipated benefits of the merger. If we do not realize the expected benefits of the merger, including the achievement of operating synergies, the merger could result in a reduction of our per share earnings as compared to the per share earnings that would have been achieved by us had the merger not occurred.

There is pending litigation. Actions purporting to be class and derivative actions on behalf of msystems and its shareholders were filed against us and msystems prior to the closing of the merger. See Part 2, Item 1, ''Legal Proceedings.’’ We may be required to expend significant resources, including management time, to defend these actions and could be subject to damages or settlement costs related to these actions. We are responsible for liabilities associated with these and any other class and derivative actions, including indemnification of directors and certain members of management of msystems.

There are risks related to msystems prior option grant practices. As a result of an investigation by a special committee of its board of directors into its prior option grant practices, on July 17, 2006, msystems filed a Form 20-F with the U.S. Securities and Exchange Commission, or SEC, in which it restated its financial statements for each of the fiscal years ended December 31, 1999 through 2005 and, in a separate report on Form 6-K, restated its financial statements for each of the four quarters of fiscal 2005 and the first quarter of fiscal 2006. In addition, msystems has disclosed that the SEC is conducting an informal investigation into msystems prior option grant practices and the restatement of its financials.

Under the merger agreement, the combined company is responsible for liabilities associated with msystems’ prior stock option grant practices, including indemnification of directors and certain members of management of msystems. These liabilities could be substantial and may include, among other things, the costs of defending lawsuits against msystems and its directors, officers, employees and former employees by stockholders and other third-parties; the cost of defending any shareholder derivative suits; the cost of governmental, law enforcement or regulatory investigations; civil or criminal fines and penalties; expenses associated with further financial restatements; auditor, legal and other expenses; and expenses associated with the remedial measures, if any, which may be imposed.
