	Organization and Summary of Significant Accounting Policies

	Organization and Nature of Operations. SanDisk Corporation (together with its subsidiaries, the “Company”) was incorporated in the State of Delaware on June 1, 1988. The Company designs, develops, markets and manufactures data storage solutions in a variety of form factors using its flash memory, controller and firmware technologies. The Company operates in one segment, flash memory storage products.

	Basis of Presentation. The Company’s fiscal year ends on the Sunday closest to December 31. All fiscal years presented consisted of 52 weeks. Certain prior period amounts have been reclassified in the financial statements and footnotes to conform to the current period presentation, including line items within current assets and property and equipment in the Consolidated Balance Sheets and Note 4, “Balance Sheet Information,” as well as cash flows from operating activities in the Consolidated Statement of Cash Flows. Beginning in the first quarter of fiscal year 2013, the Company reports only total revenue, which includes product revenue and license and royalty revenue. For accounting and disclosure purposes, the exchange rate used to convert Japanese yen to the United States (“U.S.”) dollar for fiscal years ended December 29, 2013, December 30, 2012 and January 1, 2012 was 104.94, 85.99 and 77.17, respectively. Throughout the Notes to Consolidated Financial Statements, unless otherwise indicated, references to Net income refer to Net income attributable to common stockholders.

	Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Non-controlling interest represents the minority shareholders’ proportionate share of the net assets and results of operations of the Company’s majority-owned subsidiaries. The 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 Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenue, expenses and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, intellectual property claims, product returns, allowance for doubtful accounts, inventories and inventory reserves, valuation and impairments of marketable securities and investments, valuation and impairments of goodwill and long-lived assets, income taxes, warranty obligations, restructurings, contingencies, share-based compensation and litigation. The Company bases its 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 value of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates.

	Revenue Recognition, Sales Returns and Allowances and Sales Incentive Programs. The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title and acceptance, if applicable, pricing is fixed or determinable and collectability is reasonably assured. Revenue is generally recognized at the time of shipment or transfer of title for customers not eligible for price protection and/or a right of return. Sales made to distributors and retailers are generally under agreements allowing price protection and/or a right of return and, therefore, the revenue and related costs of these transactions are deferred until the retailers or distributors sell-through the merchandise to their end customer or their rights of return expire. Estimated sales returns are recorded as a reduction to revenue and deferred revenue and were not material for any period presented in the accompanying Consolidated Financial Statements. The cost of shipping products to customers is included in cost of revenue. The Company recognizes expenses related to sales commissions in the period in which the commissions are earned.

	For multiple element arrangements and revenue arrangements that include software elements, the Company allocates revenue to each element based on its relative selling price in accordance with the Company’s normal pricing and discounting practices for the specific product or maintenance when sold separately for all multiple element products. In addition, the Company analyzes whether tangible products containing software and non-software components that function together should be excluded from industry-specific software revenue recognition guidance. Multiple element arrangements and arrangements that include software have been immaterial to the Company’s revenue and operating results.

	Revenue from patent licensing arrangements is recognized when earned, estimable and realizable. The timing of revenue recognition is dependent on the terms of each license agreement and on the timing of sales of licensed products. The Company generally recognizes royalty revenue when it is reported to the Company by its licensees, which is generally one quarter in arrears from the licensees’ sales of licensed products. For licensing fees that are not determined by the number of licensed units sold, the Company recognizes license fee revenue on a straight-line basis over the life of the license.

	The Company records estimated reductions of revenue for customer and distributor incentive programs and offerings, including price protection, promotions, co-op advertising and other volume-based incentives and expected returns. All sales incentive programs are recorded as an offset to revenue or deferred revenue. Marketing development programs are recorded as a reduction to revenue.

	Accounts Receivable and Allowance for Doubtful Accounts. Accounts receivable include amounts owed by geographically dispersed distributors, retailers and original equipment manufacturer (“OEM”) customers. No collateral is required. Provisions are provided for sales returns and credit losses.

	The Company estimates the collectability of its accounts receivable based on a combination of factors, including but not limited to, customer credit ratings and historical experience. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations to the Company (e.g., bankruptcy filings or substantial downgrading of credit ratings), the Company provides allowances for bad debts against amounts due to reduce the net recognized receivable to the amount it reasonably believes will be collected.

	Income Taxes. The Company accounts for income taxes using an asset and liability approach, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s Consolidated Financial Statements, but have not been reflected in the Company’s taxable income. The Company must evaluate the expected realization of its deferred tax assets and determine whether a valuation allowance needs to be established or released. In determining the need for and amount of a valuation allowance, the Company assesses the likelihood that it will be able to recover its deferred tax assets using historical levels of income, estimates of future income and tax planning strategies. A valuation allowance is established to the extent that the Company does not believe it is “more likely than not” that it will generate sufficient taxable income in future periods to realize the benefit of its deferred tax assets.

	The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company recognizes the tax benefit from an uncertain tax position only if it is “more likely than not” the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement.

	Foreign Currency. The Company determines the functional currency for its parent company and each of its subsidiaries by reviewing the currencies in which their respective operating activities occur. Transaction gains and losses arising from activities in other than the applicable functional currency are calculated using average exchange rates for the applicable period and reported in net income as a non-operating item in each period. Non-monetary balance sheet items denominated in a currency other than the applicable functional currency are translated using the historical rate. The Company continuously evaluates its foreign currency exposures and may continue to enter into hedges or other risk mitigating arrangements in the future. Aggregate gross foreign currency transaction gain (loss) prior to consideration of the offsetting hedges recorded to income before taxes was ($3.3) million, ($2.8) million and $18.8 million in fiscal years 2013, 2012 and 2011, respectively.

	Cash Equivalents, Short and Long-Term Marketable Securities. Cash equivalents consist of short-term, highly liquid financial instruments with insignificant interest rate risk that are readily convertible to cash and have maturities of three months or less from the date of purchase. Marketable securities with original maturities greater than three months from purchase date and remaining maturities less than one year are classified as short-term marketable securities. Marketable securities with remaining maturities greater than one year as of the balance sheet date are classified as long-term marketable securities. Short and long-term fixed income investments consist of U.S. Treasury securities, U.S. government-sponsored agency securities, international government securities, corporate notes and bonds, municipal notes and bonds, asset-backed securities and mortgage-backed securities. The fair market value of cash equivalents at December 29, 2013 approximated their carrying value. Cost of securities sold is based on specific identification.

	In determining if and when a decline in market value below cost of these investments is other-than-temporary, the Company evaluates both quantitative and qualitative information including the market conditions, offering prices, trends of earnings, price multiples and other key measures. For fixed income securities, only the decline attributable to deteriorating credit of an other-than-temporary impairment is taken to the Consolidated Statement of Operations, unless the Company intends, or “more likely than not” will be required, to sell the security.

	Property and Equipment. Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, ranging from two to twenty-five years, or the remaining lease term, whichever is shorter.

	Variable Interest Entities. The Company evaluates its equity method investments to determine whether any investee is a variable interest entity (“VIE”). If the Company concludes that an investee is a VIE, the Company evaluates its power to direct the activities of the investee, its obligation to absorb the expected losses of the investee and its right to receive the expected residual returns of the investee to determine whether the Company is the primary beneficiary of the investee. If the Company is the primary beneficiary of a VIE, the Company consolidates such entity and reflects the non-controlling interest of other beneficiaries of that entity. If the Company concludes that an investee is not a VIE, the Company does not consolidate the investee.

	Equity Investments. The Company accounts for investments in equity securities of other entities, including VIEs that are not consolidated, under the cost method of accounting if investments in voting equity interests of the investee are less than 20%. The equity method of accounting is used if the Company’s investment in voting stock is greater than or equal to 20% but less than a majority. In considering the accounting method for investments less than 20%, the Company also considers other factors such as its ability to exercise significant influence over operating and financial policies of the investee. If certain factors are present, the Company could account for investments for which it has less than a 20% ownership under the equity method of accounting.

	Investments in public companies with restrictions of less than one year are classified as available-for-sale and are adjusted to their fair market value with unrealized gains and losses recorded as a component of accumulated other comprehensive income (“AOCI”). Investments in public and non-public companies are reviewed on a quarterly basis to determine if their value has been impaired and adjustments are recorded as necessary. Upon disposition of these investments, the specific identification method is used to determine the cost basis in computing realized gains or losses. Declines in value that are judged to be other-than-temporary are reported in Interest (expense) and other income (expense), net or Cost of revenue in the accompanying Consolidated Statements of Operations.

	Inventories and Inventory Valuation. Inventories are stated at the lower of cost (first-in, first-out) or market. Market value is based upon an estimated average selling price reduced by estimated costs of disposal. Should actual market conditions differ from the Company’s estimates, the Company’s future results of operations could be materially affected. Reductions in inventory valuation are included in Cost of revenue in the accompanying Consolidated Statements of Operations. Inventory impairment charges, when taken, permanently establish a new cost basis and are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable. Rather, these amounts are recognized in income only if, as and when the inventory is sold.

	The Company reduces the carrying value of its inventory to a new basis for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of the inventory and the estimated market value based upon assumptions about future demand and market conditions, including assumptions about changes in average selling prices. If actual market conditions are less favorable than those projected by management, additional reductions in inventory valuation may be required.

	The Company’s finished goods inventory includes consigned inventory held at customer locations as well as at third-party fulfillment centers and subcontractors.

	Other Long-Lived Assets. Intangible assets with finite useful lives and other long-lived assets are tested for impairment if certain impairment indicators are identified. The Company assesses the carrying value of long-lived assets, whenever events or changes in circumstances indicate that the carrying value of these long-lived assets may not be recoverable. Factors the Company considers important which could result in an impairment review include: (1) significant under-performance relative to the historical or projected future operating results; (2) significant changes in the manner of use of assets; (3) significant negative industry or economic trends; and (4) significant changes in the Company’s market capitalization relative to net book value. Any changes in key assumptions used by the Company, including those set forth above, could result in an impairment charge and such a charge could have a material adverse effect on the Company’s consolidated results of operations.

	Advertising Expenses. Marketing co-op development programs, where the Company receives, or will receive, an identifiable benefit (e.g., goods or services) in exchange for the amount paid to its customer and the Company can reasonably estimate the fair value of the benefit it receives for the customer incentive payment, are classified, when granted, as a marketing expense. Advertising expenses not meeting this criteria are classified as a reduction to revenue when the expense is incurred. Advertising expenses recorded as marketing expense were $19.6 million, $16.2 million and $11.4 million in fiscal years 2013, 2012 and 2011, respectively.

	Research and Development Expenses. Research and development (“R&D”) expenditures are expensed as incurred.

	Investments and Fair Value Measurements

	The Company’s total cash, cash equivalents and marketable securities was as follows (in thousands):


		December 29,			December 30,
		2013			2012
	Cash and cash equivalents	$	986,246		$	995,470

	Short-term marketable securities	1,919,611			1,880,034

	Long-term marketable securities	3,179,471			2,835,931

	Total cash, cash equivalents and marketable securities	$	6,085,328		$	5,711,435


	Fair Value of Financial Instruments. For certain of the Company’s financial instruments, including cash held in banks, accounts receivable and accounts payable, the carrying amounts approximate fair value due to their short maturities, and are therefore excluded from the fair value tables below.

	The Company categorizes the fair value of its financial assets and liabilities according to the hierarchy established by the FASB, which prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are:


	Level 1	Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to directly access.
	Level 2	Valuations based on quoted prices for similar assets or liabilities; valuations for interest-bearing securities based on non-daily quoted prices in active markets; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
	Level 3	Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

	A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

	In circumstances in which a quoted price in an active market for the identical liability is not available, the Company is required to use the quoted price of the identical liability when traded as an asset, quoted prices for similar liabilities, or quoted prices for similar liabilities when traded as assets. If these quoted prices are not available, the Company is required to use another valuation technique, such as an income approach or a market approach.

	The Company’s financial assets are measured at fair value on a recurring basis. Instruments that are classified within Level 1 of the fair value hierarchy generally include money market funds and U.S. Treasury securities. Level 1 securities represent quoted prices in active markets, and therefore do not require significant management judgment.

	Instruments that are classified within Level 2 of the fair value hierarchy primarily include U.S. government-sponsored agency securities, international government securities, corporate notes and bonds, municipal notes and bonds, asset-backed securities and mortgage-backed securities. The Company’s Level 2 securities are primarily valued using quoted market prices for similar instruments and nonbinding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes and other similar data, which are obtained from independent pricing vendors, quoted market prices or other sources to determine the ultimate fair value of the Company’s assets and liabilities. The inputs and fair value are reviewed for reasonableness and may be further validated by comparison to publicly available information or compared to multiple independent valuation sources. In addition, the Company reviews third-party valuation models, independently calculates the fair value of selective financial instruments and assesses the controls at its third-party valuation service providers in determining the overall reasonableness of the fair value of its Level 2 financial instruments.

	Financial assets and liabilities measured and recorded at fair value on a recurring basis consisted of the following types of instruments (in thousands):

As of December 29, 2013 and December 30, 2012, the Company had no financial assets or liabilities categorized as Level 3 and had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted.

Available-for-Sale Investments. Available-for-sale investments were as follows (in thousands):

The fair value and gross unrealized loss on the available-for-sale securities that have been in a continuous unrealized loss position, aggregated by type of investment instrument for 12 months or less, are summarized in the following table (in thousands). As of December 29, 2013, the Company had an immaterial amount of securities that have been in a continuous unrealized loss position for more than twelve months. The unrealized loss on these securities was immaterial. Available-for-sale securities that were in an unrealized gain position have been excluded from the table.


	Fair Value			Gross Unrealized Loss
U.S. Treasury securities	$	136,621		$	(424	)

U.S. government-sponsored agency securities	2,858			(1		)

International government securities	36,265			(224		)

Corporate notes and bonds	453,671			(1,565		)

Asset-backed securities	129,855			(170		)

Mortgage-backed securities	64,811			(554		)

Municipal notes and bonds	430,620			(1,241		)

Total	$	1,254,701		$	(4,179	)


The gross unrealized loss related to U.S. Treasury securities, U.S. government-sponsored agency securities, international government securities, corporate and municipal notes and bonds, and mortgage-backed securities was primarily due to changes in interest rates. The gross unrealized loss on all available-for-sale fixed income securities at December 29, 2013 was considered temporary in nature. Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, and the Company’s intent and ability to hold an investment for a period of time sufficient to allow for any anticipated recovery in market value. For debt security investments, the Company considered additional factors including the Company’s intent to sell the investments or whether it is “more likely than not” the Company will be required to sell the investments before the recovery of its amortized cost.

The following table shows the gross realized gains and (losses) on sales of available-for-sale securities (in thousands).


	Fiscal years ended
	December 29,			December 30,			January 1,
	2013			2012			2012
Gross realized gains	$	4,724		$	3,867		$	36,762

Gross realized losses	(2,349		)	(898		)	(2,213		)

Fixed income securities by contractual maturity as of December 29, 2013 are shown below (in thousands). Actual maturities may differ from contractual maturities because issuers of the securities may have the right to prepay obligations or the Company has the option to demand payment.


	Amortized Cost			Fair Value

	Derivatives and Hedging Activities

	The Company uses derivative instruments primarily to manage exposures to foreign currency. The Company’s primary objective in holding derivative instruments is to reduce the volatility of earnings and cash flows associated with changes in foreign currency. The program is not designated for trading or speculative purposes. The Company’s derivative instruments expose the Company to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. The Company seeks to mitigate such risk by limiting its counterparties to major financial institutions and by spreading the risk across several major financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored by the Company on an ongoing basis.

	The Company recognizes derivative instruments as either assets or liabilities on the balance sheet at fair value and provides qualitative disclosures about objectives and strategies for using derivative instruments, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. Changes in fair value (i.e., gains or losses) of the derivatives are recorded as cost of revenue or other income (expense), or as other comprehensive income (“OCI”). The Company does not offset or net the fair value amounts of derivative instruments and separately discloses the fair value amounts of the derivative instruments as either assets or liabilities.

	Cash Flow Hedges. The Company uses foreign exchange forward contracts designated as cash flow hedges to hedge a portion of future forecasted wafer purchases and R&D expenses in Japanese yen. The gain or loss on the effective portion of a cash flow hedge is initially reported as a component of AOCI and subsequently reclassified into cost of revenue or R&D expense in the same period or periods in which the cost of revenue or R&D expenses are recognized, or reclassified into other income (expense) if the hedged transaction becomes probable of not occurring. Any gain or loss after a hedge is no longer designated, because it is no longer probable of occurring or it is related to an ineffective portion of a cash flow hedge, as well as any amount excluded from the Company’s hedge effectiveness, is recognized as other income (expense) immediately. As of December 29, 2013, the notional amount and unrealized loss on the effective portion of the Company’s outstanding foreign exchange forward contracts to purchase Japanese yen that are designated as cash flow hedges are shown in both Japanese yen (in billions) and U.S. dollar (in thousands), based upon the exchange rate as of December 29, 2013, as follows:


		Notional Amount								Unrealized Loss
		(Japanese yen)				(U.S. dollar)				(U.S. dollar)
	Foreign exchange forward contracts:
	Maturities 12 months or less	¥	69.4			$	662,190			$	(38,375	)

	Maturities greater than 12 months	0.2				2,295				(118		)

	Total	¥	69.6			$	664,485			$	(38,493	)


	The forward contracts with maturities greater than 12 months will settle by January 2015.

	Other Derivatives. Other derivatives that are non-designated consist primarily of foreign exchange forward contracts to minimize the risk associated with the foreign exchange effects of revaluing monetary assets and liabilities. Monetary assets and liabilities denominated in foreign currencies and the associated outstanding foreign exchange forward contracts were marked-to-market at December 29, 2013 with realized and unrealized gains and losses included in other income (expense). As of December 29, 2013, the Company had foreign exchange forward contracts hedging exposures in European euros, British pounds and Japanese yen. Foreign exchange forward contracts were outstanding to buy and sell U.S. dollar equivalents of approximately $185.2 million and $98.7 million in foreign currencies, respectively, based upon the exchange rates at December 29, 2013.

The majority of the Company’s products have a warranty of less than three years, with a small number of products having a warranty ranging up to ten years or more. For warranties ten years or greater, including lifetime warranties, the Company uses the estimated useful life of the product to calculate the warranty exposure. A provision for the estimated future cost related to warranty expense is recorded at the time of customer invoice. The Company’s warranty liability is affected by customer and consumer returns, product failures, number of units sold and repair or replacement costs incurred. Should actual product failure rates, or repair or replacement costs, differ from the Company’s estimates, increases or decreases to its warranty liability would be required.

	Goodwill. Goodwill balances and activity during fiscal year 2013 were as follows (in thousands):


		Carrying Amount
	Balance as of December 30, 2012	$	201,735

	Acquisition	115,775

	Adjustment	601

	Balance as of December 29, 2013	$	318,111


	Goodwill increased by approximately $115.8 million due to the Company’s acquisition of SMART Storage Systems (“SMART Storage”) during the third quarter of fiscal year 2013. See Note 15, “Business Acquisition” regarding this acquisition. In addition, goodwill increased by $0.6 million during the first quarter of fiscal year 2013 due to the resolution of a legal contingency matter during the measurement period for an acquisition from fiscal year 2012.

	Goodwill is not amortized, but is reviewed and tested for impairment at least annually, on the first day of the Company’s fourth quarter and whenever events or circumstances occur that indicate that goodwill might be impaired. Impairment of goodwill is tested at the Company’s reporting unit level. The Company has the option to first assess qualitative factors to determine whether events and circumstances indicate that it is more likely than not that the goodwill is impaired and determine whether further action is needed (“Step 0”). For the year ended December 29, 2013, the Company performed a Step 0 qualitative assessment of its goodwill and did not identify any events or circumstances that would indicate an impairment of goodwill. As such, the Company did not perform any further goodwill impairment testing.

Gross acquisition-related intangible assets and acquired in-process research and development (“IPR&D”) increased $168.5 million in fiscal year 2013 due to the acquisition of SMART Storage. During the fiscal year ended December 29, 2013, the Company reclassified $1.3 million of acquired IPR&D to developed product technology and commenced amortization.

The Company performs tests for impairment of long-lived assets whenever events or circumstances suggest that long-lived assets may be impaired. In the third quarter of fiscal year 2013, the Company performed impairment tests on the amortizable intangible and IPR&D assets from the Pliant Technology, Inc. (“Pliant”) acquisition. The Company performed impairment tests on these assets due to the recent SMART Storage acquisition and the decision to integrate more of the SMART Storage architecture into its future enterprise product roadmap, and due to additional product delays in the development timeline related to an IPR&D project from this acquisition. In conducting an impairment review of the Pliant amortizable intangible assets, the Company first compared the undiscounted cash flows to the carrying value of these amortizable intangible assets. Since the undiscounted cash flows were less than the carrying value, the Company then compared the estimated fair value based upon forecasted discounted cash flows to the carrying value and determined there was an impairment of $47.0 million. In addition, the Company performed an impairment analysis for the IPR&D by comparing the estimated fair value based upon forecasted discounted cash flows related to the Pliant IPR&D to the carrying value and determined there was a full impairment of $36.2 million. The Company recorded an impairment of the amortizable intangible assets and IPR&D assets totaling $83.2 million in the third quarter of fiscal year 2013, which was included in Impairment of acquisition-related intangible assets in the Consolidated Statements of Operations. The Company will continue to monitor for any events or circumstances that could indicate whether an impairment of the remaining Pliant acquisition-related intangible assets is required. The amortization schedule for the remaining Pliant acquisition-related intangible assets has been adjusted to be fully amortized by the end of fiscal year 2014, based upon the estimated remaining cash flows.

Acquired IPR&D is accounted for as an indefinite-lived intangible asset. Indefinite-lived intangible assets are reviewed for impairment at least annually until technological feasibility is achieved or development is complete. Upon completion of development, the acquired IPR&D is considered an amortizable finite-lived intangible asset. Amortization expense of technology licenses and patents is recorded to cost of revenue or R&D based upon the use of the technology. In fiscal year 2012, the Company discontinued a project related to an IPR&D indefinite-lived intangible asset, which resulted in an impairment of $0.9 million which was included in Impairment of acquisition-related intangible assets in the Consolidated Statement of Operations.

Amortization expense of intangible assets totaled $84.3 million, $76.5 million and $65.5 million in fiscal years 2013, 2012 and 2011, respectively.

The annual expected amortization expense of intangible assets subject to amortization as of December 29, 2013, is as follows (in thousands):

	1% Convertible Senior Notes Due 2013. On May 15, 2013, the maturity date for the 1% Convertible Senior Notes due May 15, 2013 (“1% Notes due 2013”), the Company settled the 1% Notes due 2013 through an all-cash transaction for principal and accrued interest of $928.1 million and $4.6 million, respectively. As of the date of the redemption, the Company had no further obligations related to the 1% Notes due 2013. In connection with the maturity of the 1% Notes due 2013, the associated convertible bond hedge and warrant transactions also terminated, with no shares purchased under the convertible bond hedge agreement and no exercises of the warrants.

	The following table presents the amount of interest cost recognized relating to the contractual interest coupon, amortization of bond issuance costs and amortization of the bond discount on the liability component of the 1% Notes due 2013 (in thousands):


		Fiscal years ended
		December 29,				December 30,				January 1,
		2013				2012				2012
	Contractual interest coupon	$	3,481			$	9,280			$	10,692

	Total interest cost recognized	$	25,516			$	65,662			$	71,461


	The effective interest rate on the liability component of the 1% Notes due 2013 was 7.4% for the three fiscal years ended December 29, 2013.

	Bond Repurchase. In the twelve months ended January 1, 2012, the Company repurchased $221.9 million principal amount of its 1% Notes due 2013 in private transactions with a limited number of bondholders for cash consideration of $211.1 million, which resulted in the recognition of a loss before tax of $11.5 million, which was recorded in other income (expense). The repurchase was economically beneficial given the notes were repurchased below the principal amount and given that interest rates on cash and marketable securities were lower than the 1% coupon rate of the notes. In accordance with current accounting guidance, at settlement, the fair value of the liability component of the convertible debt immediately prior to repurchase was measured using interest rates at settlement, and the difference between the fair value of the aggregate consideration remitted to the holders and the fair value of the liability component of the convertible debt immediately prior to repurchase is attributed to the reacquisition of the equity component. The difference between the fair value of the liability component of the convertible debt immediately prior to the repurchase and the carrying value of the debt redeemed was recorded as expense on extinguishment of debt in Interest (expense) and other income (expense), net, in the Consolidated Statements of Operations.

	In connection with the repurchase of a portion of the 1% Notes due 2013, the Company unwound a portion of the convertible bond hedge and warrants. As a result of this unwinding, the Company received net proceeds of $0.3 million, which was recorded in equity.

	1.5% Convertible Senior Notes Due 2017. In August 2010, the Company issued and sold $1.0 billion in aggregate principal amount of 1.5% Convertible Senior Notes due August 15, 2017 (the “1.5% Notes due 2017”) at par. The 1.5% Notes due 2017 may be converted, under certain circumstances described below, based on an initial conversion rate of 19.0931 shares of common stock per $1,000 principal amount of notes (which represents an initial conversion price of approximately $52.37 per share). The 1.5% Notes due 2017 contains provisions where the conversion rate and conversion price are adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. Accordingly, as of December 29, 2013, the conversion rate was adjusted for dividends paid to date to 19.2307 shares of common stock per $1,000 principal amount of notes (which represents a conversion price of approximately $52.00 per share). The net proceeds to the Company from the sale of the 1.5% Notes due 2017 were $981.0 million.

	The Company separately accounts for the liability and equity components of the 1.5% Notes due 2017. The principal amount of the liability component of $706.0 million as of the date of issuance was recognized at the present value of its cash flows using a discount rate of 6.85%, the Company’s borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. As of December 29, 2013, the carrying value of the equity component of $294.0 million was unchanged from the date of issuance.

	The following table presents the amount of interest cost recognized relating to the contractual interest coupon, amortization of bond issuance costs and amortization of the bond discount on the liability component of the 1.5% Notes due 2017 (in thousands):


	Fiscal years ended
	December 29,				December 30,				January 1,
	2013				2012				2012
Contractual interest coupon	$	15,000			$	15,000			$	15,000

Amortization of bond issuance costs	2,667				2,666				2,695

Amortization of bond discount	39,095				36,364				34,140

Total interest cost recognized	$	56,762			$	54,030			$	51,835


The effective interest rate on the liability component of the 1.5% Notes due 2017 was 6.85% for each of the three fiscal years ended December 29, 2013. The remaining unamortized bond discount of $170.2 million as of December 29, 2013 will be amortized over the remaining life of the 1.5% Notes due 2017, which is approximately 3.6 years.

The 1.5% Notes due 2017 may be converted on any day prior to the close of business on the scheduled trading day immediately preceding May 15, 2017, in multiples of $1,000 principal amount at the option of the holder under any of the following circumstances: 1) during the five business-day period after any five consecutive trading-day period (the “measurement period”) in which the trading price per note for each day of such measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such day; 2) during any calendar quarter after the calendar quarter ending September 30, 2010, if the last reported sale price of the Company’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price in effect on the last trading day of the immediately preceding calendar quarter; or 3) upon the occurrence of specified corporate transactions. On and after May 15, 2017 until the close of business on the second scheduled trading day immediately preceding the maturity date of August 15, 2017, holders may convert their notes at any time, regardless of the foregoing circumstances.

Upon conversion, a holder will receive the conversion value of the 1.5% Notes due 2017 to be converted equal to the conversion rate multiplied by the volume weighted average price of the Company’s common stock during a specified period following the conversion date. The conversion value of each 1.5% Notes due 2017 will be paid in: 1) cash equal to the lesser of the principal amount of the note or the conversion value, as defined, and 2) to the extent the conversion value exceeds the principal amount of the note, common stock (plus cash in lieu of any fractional shares of common stock). The conversion price will be subject to adjustment in some events but will not be adjusted for accrued interest. Upon a “fundamental change” at any time, as defined, the Company will in some cases increase the conversion rate for a holder who elects to convert its 1.5% Notes due 2017 in connection with such fundamental change. In addition, the holders may require the Company to repurchase for cash all or a portion of their notes upon a “designated event” at a price equal to 100% of the principal amount of the notes being repurchased plus accrued and unpaid interest, if any.

The Company pays cash interest at an annual rate of 1.5%, payable semi-annually on February 15 and August 15 of each year, beginning February 15, 2011. Debt issuance costs were $18.7 million, of which $5.5 million was allocated to capital in excess of par value and $13.2 million was allocated to deferred issuance costs and is amortized to interest expense over the term of the 1.5% Notes due 2017. As of December 29, 2013, unamortized deferred issuance cost was $6.8 million.

Concurrently with the issuance of the 1.5% Notes due 2017, the Company purchased a convertible bond hedge and sold warrants. The convertible bond hedge transaction is structured to reduce the potential future economic dilution associated with the conversion of the 1.5% Notes due 2017 and, combined with the warrants, to increase the initial conversion price to $73.3250 per share. Each of these components is discussed separately below:


•	Convertible Bond Hedge. Counterparties agreed to sell to the Company up to approximately 19.1 million shares of the Company’s common stock, which is the number of shares initially issuable upon conversion of the 1.5% Notes due 2017 in full, at a price of $52.37 per share. The 1.5% Notes due 2017 contains provisions where the number of shares to be sold under the convertible bond hedge transaction and the conversion price will be adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. After adjusting for the dividends paid through December 29, 2013, the counterparties may acquire up to approximately 19.2 million shares of the Company’s common stock, which is the number of shares issuable upon conversion of the 1.5% Notes due 2017 in full, at a price of $52.00 per share. This convertible bond hedge transaction will be settled in net shares and will terminate upon the earlier of the maturity date of the 1.5% Notes due 2017 or the first day none of the 1.5% Notes due 2017 remain outstanding due to conversion or otherwise. Settlement of the convertible bond hedge in net shares, based on the number of shares issuable upon conversion of the 1.5% Notes due 2017, on the expiration date would result in the Company receiving net shares equivalent to the number of shares issuable by the Company upon conversion of the 1.5% Notes due 2017. Should there be an early unwind of the convertible bond hedge transaction, the number of net shares potentially received by the Company will depend upon 1) the then existing overall market conditions, 2) the Company’s stock price, 3) the volatility of the Company’s stock, and 4) the amount of time remaining before expiration of the convertible bond hedge. The convertible bond hedge transaction cost of $292.9 million has been accounted for as an equity transaction. The Company initially recorded approximately $1.7 million in stockholders’ equity from the deferred tax asset related to the convertible bond hedge at inception of the transaction. As of December 29, 2013, the Company had not purchased any shares under this convertible bond hedge agreement.


•	Warrants. The Company received $188.1 million from the same counterparties from the sale of warrants to purchase up to approximately 19.1 million shares of the Company’s common stock at an exercise price of $73.3250 per share. The 1.5% Notes due 2017 contains provisions whereby the number of shares to be acquired under the warrants and the strike price are adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. After adjusting for the dividends paid through December 29, 2013, holders of the warrants may acquire up to approximately 19.2 million shares of the Company’s common stock at a strike price of $72.8005 per share. The warrants mature on 40 different dates from November 13, 2017 through January 10, 2018 and are exercisable at the maturity date. At each expiration date, the Company may, at its option, elect to settle the warrants on a net share basis. As of December 29, 2013, the warrants had not been exercised and remained outstanding. The value of the warrants was initially recorded in equity and continues to be classified as equity.

0.5% Convertible Senior Notes Due 2020. In October 2013, the Company issued and sold $1.5 billion in aggregate principal amount of 0.5% Convertible Senior Notes due October 15, 2020 (the “0.5% Notes due 2020”) at par. The 0.5% Notes due 2020 may be converted, under certain circumstances described below, based on an initial conversion rate of 10.8470 shares of common stock per $1,000 principal amount of notes (which represents an initial conversion price of approximately $92.19 per share). The 0.5% Notes due 2020 contains provisions where the conversion rate and conversion price are adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock. As of December 29, 2013, no adjustment has been made to the conversion rate or the conversion price. The net proceeds to the Company from the sale of the 0.5% Notes due 2020 were approximately $1.48 billion.

The Company separately accounts for the liability and equity components of the 0.5% Notes due 2020. The principal amount of the liability component of $1.15 billion as of the date of issuance was recognized at the present value of its cash flows using a discount rate of 4.43%, the Company’s borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. As of December 29, 2013, the carrying value of the equity component of $352.0 million was unchanged from the date of issuance.

The following table presents the amount of interest cost recognized relating to the contractual interest coupon, amortization of bond issuance costs and amortization of the bond discount on the liability component of the 0.5% Notes due 2020 (in thousands):


	Fiscal year ended
	December 29,
	2013
Contractual interest coupon	$	1,271

Amortization of bond issuance costs	439

Amortization of bond discount	7,486

Total interest cost recognized	$	9,196


The effective interest rate on the liability component of the 0.5% Notes due 2020 was 4.43% for the fiscal year ended December 29, 2013. The remaining unamortized bond discount of $344.4 million as of December 29, 2013 will be amortized over the remaining life of the 0.5% Notes due 2020, which is approximately 6.8 years.

The 0.5% Notes due 2020 may be converted on any day prior to the close of business on the scheduled trading day immediately preceding July 15, 2020, in multiples of $1,000 principal amount at the option of the holder under any of the following circumstances: 1) during the five business-day period after any five consecutive trading-day period (the “measurement period”) in which the trading price per note for each day of such measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such day; 2) during any calendar quarter after the calendar quarter ending December 29, 2013, if the last reported sale price of the Company’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price in effect on the last trading day of the immediately preceding calendar quarter; or 3) upon the occurrence of specified corporate transactions. On and after July 15, 2020 until the close of business on the second scheduled trading day immediately preceding the maturity date of October 15, 2020, holders may convert their notes at any time, regardless of the foregoing circumstances.

Upon conversion, a holder will receive the conversion value of the 0.5% Notes due 2020 to be converted equal to the conversion rate multiplied by the volume weighted average price of the Company’s common stock during a specified period following the conversion date. The conversion value of each 0.5% Notes due 2020 will be paid in: 1) cash equal to the lesser of the principal amount of the note or the conversion value, as defined, and 2) to the extent the conversion value exceeds the principal amount of the note, common stock (plus cash in lieu of any fractional shares of common stock). The conversion price will be subject to adjustment in some events but will not be adjusted for accrued interest. Upon a “fundamental change” at any time, as defined, the Company will in some cases increase the conversion rate for a holder who elects to convert its 0.5% Notes due 2020 in connection with such fundamental change. In addition, the holders may require the Company to repurchase for cash all or a portion of their notes upon a “designated event” at a price equal to 100% of the principal amount of the notes being repurchased plus accrued and unpaid interest, if any.

The Company pays cash interest at an annual rate of 0.5%, payable semi-annually on April 15 and October 15 of each year, beginning April 15, 2014. Debt issuance costs were approximately $18.5 million, of which $4.3 million was allocated to capital in excess of par value and $14.1 million was allocated to deferred issuance costs and is amortized to interest expense over the term of the 0.5% Notes due 2020. As of December 29, 2013, unamortized deferred issuance cost was $13.8 million.

Concurrently with the issuance of the 0.5% Notes due 2020, the Company purchased a convertible bond hedge and sold warrants. The convertible bond hedge transaction is structured to reduce the potential future economic dilution associated with the conversion of the 0.5% Notes due 2020 and, combined with the warrants, to increase the initial conversion price to $122.9220 per share. Each of these components is discussed separately below:


•	Convertible Bond Hedge. Counterparties agreed to sell to the Company up to approximately 16.3 million shares of the Company’s common stock, which is the number of shares initially issuable upon conversion of the 0.5% Notes due 2020 in full, at a price of $92.19 per share. The 0.5% Notes due 2020 contains provisions where the number of shares to be sold under the convertible bond hedge transaction and the conversion price will be adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock. As of December 29, 2013, no adjustment has been made to the number of shares to be sold under the convertible bond hedge transaction or the conversion price. This convertible bond hedge transaction will be settled in net shares and will terminate upon the earlier of the maturity date of the 0.5% Notes due 2020 or the first day none of the 0.5% Notes due 2020 remain outstanding due to conversion or otherwise. Settlement of the convertible bond hedge in net shares, based on the number of shares issuable upon conversion of the 0.5% Notes due 2020, on the expiration date would result in the Company receiving net shares equivalent to the number of shares issuable by the Company upon conversion of the 0.5% Notes due 2020. Should there be an early unwind of the convertible bond hedge transaction, the number of net shares potentially received by the Company will depend upon 1) the then existing overall market conditions, 2) the Company’s stock price, 3) the volatility of the Company’s stock, and 4) the amount of time remaining before expiration of the convertible bond hedge. The convertible bond hedge transaction cost of $331.7 million has been accounted for as an equity transaction. The Company initially recorded approximately $119.5 million in stockholders’ equity from the deferred tax asset related to the convertible bond hedge at inception of the transaction. As of December 29, 2013, the Company had not purchased any shares under this convertible bond hedge agreement.


•	Warrants. The Company received $217.8 million from the same counterparties from the sale of warrants to purchase up to approximately 16.3 million shares of the Company’s common stock at an exercise price of $122.9220 per share. The 0.5% Notes due 2020 contains provisions whereby the number of shares to be acquired under the warrants and the strike price are adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock. As of December 29, 2013, no adjustment has been made to the number of shares to be acquired under the warrants or the strike price. The warrants mature on 40 different dates from January 13, 2021 through March 11, 2021 and are exercisable at the maturity date. At each expiration date, the Company may, at its option, elect to settle the warrants on a net share basis. As of December 29, 2013, the warrants had not been exercised and remained outstanding. The value of the warrants was initially recorded in equity and continues to be classified as equity.

	Share Repurchase Program

	In September 2013, the Company’s Board of Directors increased the share repurchase program authorization by $2.50 billion, to an aggregate amount of $3.75 billion for share repurchases. Under this program, shares repurchased are recorded as a reduction to capital in excess of par value and retained earnings in the Company’s Consolidated Balance Sheets. The repurchases will be made from time to time in the open market, in privately negotiated transactions, or in structured stock repurchase programs, and may be made in one or more repurchases, in compliance with Rule 10b-18 of the Securities Exchange Act, subject to market conditions, applicable legal requirements, and other factors. The program does not obligate the Company to acquire any particular amount of common stock, and the program may be suspended at any time at the Company’s discretion. As part of the share repurchase program, the Company has entered into, and may continue to enter into, structured share repurchase transactions with financial institutions. These agreements generally require that the Company make an up-front payment in exchange for the right to receive a fixed number of shares of its common stock upon execution of the agreement, with a potential increase or decrease in the number of shares at the end of the term of the agreement.

	On July 31, 2013, the Company entered into an accelerated share repurchase (“ASR”) agreement with a financial institution to purchase $1.0 billion of the Company’s common stock. In exchange for up-front payments totaling $1.0 billion, the financial institution committed to deliver shares during the ASR’s purchase period, which will end no later than April 8, 2014. The total number of shares ultimately delivered, and therefore the average price paid per share, will be determined at the end of the purchase period based on the volume weighted average price of the Company’s stock during the period. During the third quarter of fiscal year 2013, 14.5 million shares under this ASR program were initially delivered to the Company. This does not represent the final number of shares to be delivered under the ASR. Depending on the average price of the Company’s common stock while the ASR is outstanding, upon the maturity of the ASR, the financial institution may be required to deliver additional shares to the Company or the Company may be required to deliver shares to the financial institution. The up-front payment of $1.0 billion was accounted for as a reduction to stockholders’ equity in the Company’s Consolidated Balance Sheet.

	The Company reflected the ASR as a repurchase of common stock for purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The forward contract met all of the applicable criteria for equity classification, and therefore, was not accounted for as a derivative instrument.

	Concurrent with the issuance of the 0.5% Notes due 2020, the Company used approximately $150.0 million of the net proceeds of the 0.5% Notes due 2020 to repurchase 2.2 million shares of its common stock.

	From inception through December 29, 2013, the Company has repurchased on the open market 30.4 million shares for an aggregate purchase price of $1.82 billion, of which 24.7 million shares for an aggregate purchase price of $1.59 billion, including the ASR, were repurchased during fiscal year 2013.

	As of December 29, 2013, the remaining authorized spending under the Company’s share repurchase program was $1.93 billion.

	Geographic Information and Major Customers. The Company markets and sells flash memory products in the U.S. and in foreign countries through its sales personnel, dealers, distributors, retailers and subsidiaries. The Company’s Chief Operating Decision Maker, its President and Chief Executive Officer, evaluates performance of the Company and makes decisions regarding allocation of resources based on total Company results. Since the Company operates in one segment, all financial segment information can be found in the accompanying Consolidated Financial Statements.

	Other than sales in the U.S., China, South Korea and Taiwan, no individual country represented more than 10% of the Company’s revenue. Intercompany sales between geographic areas have been eliminated.

	Revenue by geographic areas for fiscal years 2013, 2012 and 2011 were as follows (in thousands):


		Fiscal years ended

	Other foreign countries	47,070		38,702

	Total	$	1,214,051	$	1,308,623


	Long-lived assets are attributed to the geographic location in which they are located. The Company includes in long-lived assets property and equipment, long-term equity investments in Flash Ventures and other equity investments, and attributes those investments to the location of the investee’s primary operations.

	Customer and Supplier Concentrations. A limited number of customers or licensees have accounted for a substantial portion of the Company’s revenue. Revenue from the Company’s top 10 customers or licensees accounted for approximately 49%, 43% and 48% of the Company’s revenue for fiscal years 2013, 2012 and 2011, respectively. In fiscal year 2013 and 2012, Apple Inc. (“Apple”) accounted for 20% and 13% of the Company’s revenue, respectively. In fiscal year 2011, Samsung Electronics Co., Ltd. accounted for 10% of the Company’s revenue. Apple primarily purchases mobile embedded products and solid state drive (“SSD”) products from the Company.
	All of the Company’s flash memory system products require silicon wafers for the memory and controller components. The Company’s memory wafers are currently supplied almost entirely from Flash Ventures and the controller wafers are all manufactured by third-party subcontractors. The failure of any of these sources to deliver silicon wafers could have a material adverse effect on the Company’s business, financial condition and results of operations. Moreover, the employees of Toshiba Corporation (“Toshiba”) that produce Flash Ventures’ products are covered by collective bargaining agreements and any strike or other job action by those employees could interrupt the Company’s wafer supply from Toshiba’s Yokkaichi, Japan operations.

	In addition, some key components are purchased from single source vendors for which alternative sources are currently not available. Shortages could occur in these essential materials due to an interruption of supply or increased demand in the industry. If the Company were unable to procure certain of such materials, it could reduce sales, which could have a material adverse effect upon its results of operations. The Company also relies on third-party subcontractors to assemble and test a portion of its products. The Company does not have long-term contracts with some of these subcontractors and cannot directly control product delivery schedules or manufacturing processes. This could lead to product shortages or quality assurance problems that could increase the manufacturing costs of the Company’s products and have material adverse effects on the Company’s operating results.

	Concentration of Credit Risk. The Company’s concentration of credit risk consists principally of cash, cash equivalents, short and long-term marketable securities and trade receivables. The Company’s investment policy restricts investments to high-credit quality investments and limits the amounts invested with any one issuer. The Company sells to Commercial and Retail customers in the Americas; Europe, Middle East and Africa (“EMEA”); and Asia-Pacific, and performs ongoing credit evaluations of its customers’ financial condition, and generally requires no collateral. As of end of fiscal years 2013 and 2012, the Company’s top 10 customers or licensees accounted for approximately 64% of the Company’s net accounts receivable in each of these fiscal years. As of end of fiscal year 2013, Apple and Best Buy Co., Inc. accounted for 32% and 11% of the Company’s net accounts receivable, respectively. As of the end of fiscal year 2012, Apple accounted for 34% of the Company’s net accounts receivable.

	Off-Balance Sheet Risk. The Company has off-balance sheet financial obligations. See Note 12, “Commitments, Contingencies and Guarantees.”

Future dividends are subject to declaration by the Company’s Board of Directors.

	Share-based Benefit Plans

	2013 Incentive Plan. On June 12, 2013, the Company’s stockholders approved the 2013 Incentive Plan (“2013 Plan”). Shares of the Company’s common stock may be issued under the 2013 Plan pursuant to two separate equity incentive programs: (i) the discretionary grant program under which stock options and stock appreciation rights may be granted to officers and other employees, non-employee board members and independent consultants, and (ii) the stock issuance and cash bonus program under which eligible persons may, at the discretion of the plan administrator, be issued shares of the Company’s common stock pursuant to restricted stock awards, restricted stock units (“RSUs”) or other share-based awards which vest upon the completion of a designated service period or the attainment of pre-established performance milestones, be awarded cash bonus opportunities which are earned through the attainment of pre-established performance milestones, or be issued shares of the Company’s common stock through direct purchase or as a bonus for services rendered to the Company. Options eligible for exercise may be exercised for shares of the Company’s common stock at any time prior to the expiration of the seven-year option term or any earlier termination of those options in connection with the optionee’s cessation of service with the Company. Outstanding RSU awards under the 2013 Plan have dividend equivalent rights which entitle holders of RSUs to the same dividend value per share as holders of common stock. Dividend equivalent rights are subject to the same vesting and other terms and conditions as the corresponding unvested RSUs. Dividend equivalent rights are accumulated and paid when the underlying shares vest. A total of 20,000,000 shares of the Company’s common stock have initially been reserved for issuance under the 2013 Plan. The 2013 Plan share reserve may be increased by up to 10,000,000 shares of common stock to the extent that outstanding share-based awards under the 1995 Stock Option Plan, the 1995 Non-Employee Directors Stock Option Plan, and the 2005 Incentive Plan expire, terminate or lapse, of which 349,675 shares of common stock as of December 29, 2013 had been added to the 2013 Plan share reserve. All options granted under the 2013 Plan are granted with an exercise price equal to the fair market value of the common stock on the date of grant and will expire seven years from the date of grant.

	2005 Incentive Plan. The 2005 Incentive Plan terminated on June 12, 2013 and no further share-based awards were made under this plan after that date. Share-based awards that were outstanding under this plan on December 29, 2013 continue to be governed by their existing terms. Options eligible for exercise may be exercised for shares of the Company’s common stock at any time prior to the expiration of the seven-year option term or any earlier termination of those options in connection with the optionee’s cessation of service with the Company. Outstanding RSU awards under this plan have dividend equivalent rights which entitle holders of RSUs to the same dividend value per share as holders of common stock. Dividend equivalent rights are subject to the same vesting and other terms and conditions as the corresponding unvested RSUs.

	1995 Stock Option Plan and 1995 Non-Employee Directors Stock Option Plan. Both of these plans terminated on May 27, 2005 and no further option grants were made under the plans after that date. Options eligible for exercise that were outstanding under these plans on December 29, 2013 continue to be governed by their existing terms and may be exercised for shares of the Company’s common stock at any time prior to the expiration of the ten-year option term or any earlier termination of those options in connection with the optionee’s cessation of service with the Company.

	2005 Employee Stock Purchase Plan. The 2005 Employee Stock Purchase Plan (“ESPP”) was approved by the stockholders on May 27, 2005. The ESPP allows eligible employees to purchase shares of the Company’s common stock at the end of each six-month offering period at a purchase price equal to 85% of the lower of the fair market value per share on the start date of the offering period or the fair market value per share on the purchase date. The ESPP has 10,000,000 shares reserved for issuance, of which 4,345,666 shares were available to be issued as of December 29, 2013. In fiscal years 2013, 2012 and 2011, a total of 623,887 shares, 684,646 shares and 613,452 shares of common stock, respectively, were issued under this plan.

	Acquired Plans. In connection with the Company’s acquisitions of SMART Storage, FlashSoft, Pliant, msystems Ltd. and Matrix Semiconductor, Inc., the Company adopted various equity incentive plans, which were effective upon completion of the applicable acquisition. Each of these plans was terminated as of the date of acquisition and no further grants were made under any of these plans after their termination. Any unvested option grants that were outstanding under these plans at December 29, 2013 continue to be governed by their existing terms and may be exercised for shares of the Company’s common stock. Vested options may be exercised for shares of the Company’s common stock at any time prior to the expiration of the option term or any earlier termination of those options in connection with the optionee’s cessation of service with the Company.

	Accounting for Share-based Compensation Expense

	For share-based awards expected to vest, compensation cost is based on the grant-date fair value. The Company recognizes compensation expense for the fair values of these awards, which have graded vesting, on a straight-line basis over the requisite service period of each of these awards, net of estimated forfeitures.

	The Company estimates the fair value of stock options and RSUs granted using the Black-Scholes-Merton option-pricing formula and a single-option award approach. The Company’s expected term represents the period that the Company’s share-based awards are expected to be outstanding and was determined based on historical experience for similar awards, giving consideration to the contractual terms of the share-based awards. The Company’s expected volatility is based on the implied volatility of its traded options. The Company’s dividend yield is based on the annualized dividend and the share price at each dividend record date. The risk-free interest rate is based on the yield from U.S. Treasury zero-coupon bonds with an equivalent term.

	Valuation Assumptions

	Option Plan Shares. The fair value of the Company’s stock options granted, excluding unvested stock options assumed through acquisitions, was estimated using the following weighted average assumptions:


		Fiscal years ended
		December 29,		December 30,		January 1,
		2013		2012		2012
	Dividend yield	0% - 1.63%		—%		—%
	Expected volatility	0.37		0.43		0.43
	Risk-free interest rate	0.74%		0.60%		1.49%
	Expected term	4.4 years		4.3 years		4.3 years
	Estimated annual forfeiture rate	8.51%		8.59%		8.57%
	Weighted average fair value at grant date	$16.26		$16.45		$17.37

	The fair value of the Company’s RSU awards granted was valued using the closing price of the Company’s stock price on the date of grant.

	Employee Stock Purchase Plan Shares. The fair value of the Company’s ESPP shares for plans entered into during the fiscal year was estimated using the following weighted average assumptions:


		Fiscal years ended
		December 29,		December 30,		January 1,
		2013		2012		2012
	Dividend yield	0% - 1.63%		—%		—%

Options and SARs exercisable at December 29, 2013	3,208			33.99				3.1		116,294


At December 29, 2013, the total unrecognized compensation cost related to stock options, net of estimated forfeitures, was approximately $47.4 million, and this amount is expected to be recognized over a weighted average period of approximately 2.2 years. As of December 29, 2013, the Company had fully expensed all of its SARs awards.

Restricted Stock Units. RSUs are settled in shares of the Company’s common stock upon vesting on a one-for-one basis. Typically, vesting of RSUs 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 grant, and compensation is recognized on a straight-line basis over the requisite vesting period.

A summary of the changes in RSUs outstanding under the Company’s share-based compensation plans during the three fiscal years ended December 29, 2013 is presented below (in thousands, except for weighted average grant date fair value):


	Shares			Weighted Average Grant Date Fair Value				Aggregate Intrinsic Value

	Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax return reporting purposes. Significant components of the Company’s net deferred tax assets were as follows (in thousands):


	December 29,				December 30,
	2013				2012
Deferred tax assets:
Deferred income on shipments to distributors and retailers and deferred revenue recognized for tax purposes	$	68,117			$	46,679

The Company assesses its valuation allowance recorded against deferred tax assets on a regular and periodic basis. The assessment of valuation allowance against deferred tax assets requires estimations and significant judgment. The Company continues to assess and adjust its valuation allowance based on operating results and market conditions. During fiscal years 2013, 2012 and 2011, based on weighing both the positive and negative evidence available, including but not limited to, earnings history, projected future outcomes, industry and market trends and the nature of each of the deferred tax assets, the Company determined that it is able to realize most of its deferred tax assets with the exception of certain loss and credit carryforwards.

The Company has federal and state net operating loss carryforwards of $86.4 million and $136.2 million, respectively. The net operating losses will begin to expire in fiscal year 2014 if not utilized. The Company also has California research credit carryforwards of $54.9 million. California research credits can be carried forward to future years indefinitely. Some of these carryforwards are subject to annual limitations, including under Section 382 and Section 383 of the U.S. Internal Revenue Code of 1986, as amended, for U.S. tax purposes and similar state provisions.

The Company provides for U.S. income taxes on the earnings of foreign subsidiaries unless the earnings are considered indefinitely invested outside of the U.S. No provision has been made for U.S. income taxes or foreign withholding taxes on $752.2 million of cumulative unremitted earnings of certain foreign subsidiaries as of December 29, 2013, since the Company intends to indefinitely reinvest these earnings outside the U.S. The Company determined that the calculation of the amount of unrecognized deferred tax liability related to these cumulative unremitted earnings was not practicable. If these earnings were distributed to the Company’s U.S. entity, the Company would be subject to additional U.S. income taxes and foreign withholding taxes would be reduced by available foreign tax credits.

The tax benefit from share-based plans was applied to capital in excess of par value in the amount of $0.6 million, $11.7 million and $20.5 million in fiscal years 2013, 2012 and 2011, respectively.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):


Balance at January 1, 2012	$	185,826

Additions:
Tax positions related to current year	8,164

Tax positions related to prior years	942

Reductions:
Tax positions related to prior years	(7,186		)
Expiration of statute of limitations	(2,003		)
Foreign currency translation adjustment	(6,221		)
Balance at December 30, 2012	179,522

Additions:
Tax positions related to current year	8,255

Tax positions related to prior years	15,938

Reductions:
Tax positions related to prior years	(1,737		)
Expiration of statute of limitations	(7,419		)
Foreign currency translation adjustment	(9,309		)
Balance at December 29, 2013	$	185,250


The total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, is $92.1 million at December 29, 2013. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. Accrued interest and penalties included in the Company’s liability related to unrecognized tax benefits at December 29, 2013 and December 30, 2012 was $32.7 million and $32.2 million, respectively. Interest and penalties, net, included in the Company’s tax expense was $2.2 million, $2.9 million and $3.2 million for fiscal years 2013, 2012 and 2011, respectively.

It is reasonably possible that the unrecognized tax benefits could decrease by approximately $10.2 million within the next 12 months as a result of the expiration of statutes of limitation. The Company is currently under audit by several tax authorities. Because timing of the resolution and/or closure of these audits is highly uncertain it is not possible to estimate other changes to the amount of unrecognized tax benefits for positions existing at December 29, 2013.

The Company is subject to U.S. federal income tax as well as income taxes in multiple state and foreign jurisdictions. In February 2012, the Internal Revenue Service (“IRS”) completed its field audit of the Company’s federal income tax returns for the years 2005 through 2008 and issued the Revenue Agent’s Report. The most significant proposed adjustments are comprised of related party transactions between the Company’s U.S. parent entity and its foreign subsidiaries. The Company is contesting these adjustments through the IRS Appeals Office and cannot predict when a resolution will be reached.

The Company strongly believes the IRS’s position regarding the intercompany transactions is inconsistent with applicable tax laws, judicial precedents and existing Treasury regulations, and that the Company’s previously reported income tax provisions for the years in question are appropriate. The Company believes that an adequate provision has been made for the adjustments from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner that is not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs.

The IRS recently initiated an examination of the Company’s federal income tax returns for fiscal years 2009 through 2011. The Company does not expect a resolution of this audit to be reached during the next twelve months. In addition, the Company is currently under audit by various state and international tax authorities. The Company cannot reasonably estimate the outcome of these examinations, or provide assurance that the outcome of these examinations will not materially harm the Company’s financial position, results of operations or liquidity.

	Flash Ventures

	Flash Ventures, the Company’s business ventures with Toshiba, consists of three separate legal entities: Flash Partners Ltd., Flash Alliance Ltd. and Flash Forward Ltd. The Company has a 49.9% ownership interest in each of these entities and Toshiba owns 50.1% of each of these entities. Through these ventures, the Company and Toshiba have collaborated in the development and manufacture of NAND flash memory products which are manufactured by Toshiba at its wafer fabrication facility located in Yokkaichi, Japan, using semiconductor manufacturing equipment owned or leased by Flash Ventures. The Flash Ventures purchase wafers from Toshiba at cost and then resell those wafers to the Company and Toshiba at cost plus a markup. The Company accounts for its 49.9% ownership position in each Flash Ventures entity under the equity method of accounting. The Company is committed to purchase its provided three-month forecast of Flash Ventures’ NAND wafer supply, which generally equals 50% of Flash Ventures’ output. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% of Flash Ventures’ costs to the extent that Flash Ventures’ revenue from wafer sales to the Company and Toshiba are insufficient to cover these costs.

	Flash Partners. Flash Partners Ltd. (“Flash Partners”) was formed in fiscal year 2004. NAND flash memory products provided to the Company by this venture are manufactured by Toshiba at its 300-millimeter wafer fabrication facility (“Fab 3”) located in Yokkaichi, Japan. As of December 29, 2013, the Company had notes receivable from Flash Partners of $100.1 million, denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Partners with the note proceeds. The Company also has guarantee obligations to Flash Partners; see “Off-Balance Sheet Liabilities.” At December 29, 2013 and December 30, 2012, the Company had an equity investment in Flash Partners of $190.7 million and $232.5 million, respectively, denominated in Japanese yen, offset by $17.3 million and $59.3 million, respectively, of cumulative translation adjustments recorded in AOCI. In the fiscal years ended December 29, 2013, December 30, 2012 and January 1, 2012, the Company recorded a basis adjustment of $1.2 million, $3.0 million and $5.3 million, respectively, to its equity in earnings from Flash Partners related to the difference between the basis in the Company’s equity investment compared to the historical basis of the assets recorded by Flash Partners. Flash Partners’ share of the Fab 3 fabrication facility is fully equipped.

	Flash Alliance. Flash Alliance Ltd. (“Flash Alliance”) was formed in fiscal year 2006. NAND flash memory products provided to the Company by this venture are manufactured by Toshiba at its 300-millimeter wafer fabrication facility (“Fab 4”) located in Yokkaichi, Japan. As of December 29, 2013, the Company had notes receivable from Flash Alliance of $324.0 million, denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Alliance with the note proceeds. The Company also has guarantee obligations to Flash Alliance; see “Off-Balance Sheet Liabilities.” At December 29, 2013 and December 30, 2012, the Company had an equity investment in Flash Alliance of $284.0 million and $342.0 million, respectively, denominated in Japanese yen, offset by ($8.7) million and $53.7 million, respectively, of cumulative translation adjustments recorded in AOCI. In the fiscal years ended December 29, 2013, December 30, 2012 and January 1, 2012, the Company recorded a basis adjustment of $6.5 million, $15.2 million and $24.5 million, respectively, to its equity earnings from Flash Alliance related to the difference between the basis in the Company’s equity investment compared to the historical basis of the assets recorded by Flash Alliance. Flash Alliance’s share of the Fab 4 fabrication facility is fully equipped.

	Flash Forward. Flash Forward Ltd. (“Flash Forward”) was formed in fiscal year 2010. NAND flash memory products provided to the Company by this venture are manufactured by Toshiba at its 300-millimeter wafer fabrication facility (“Fab 5”) located in Yokkaichi, Japan. Fab 5 is to be built in two phases. As of December 29, 2013, over half of the Phase 1 building has been equipped with wafer capacity or equipment required to enable technology transition of the Flash Ventures’ wafer capacity. The Company regularly seeks to enhance wafer output through productivity improvements. In addition to what it may obtain through these improvements, the Company is currently evaluating the timing of a limited increase in wafer capacity in Flash Forward in fiscal year 2014. The Company and Toshiba each retain some flexibility as to the extent and timing of each party’s respective fab capacity ramps. Construction of the Phase 2 shell of the Fab 5 wafer fabrication facility is underway with expected completion in mid-2014. The Phase 2 shell is currently intended to be used primarily for technology transition of the existing Flash Ventures wafer capacity to 1Y‑nanometer and 1Z‑nanometer technology nodes and for a 3‑dimensional NAND (“3D NAND”) pilot line.

	As of December 29, 2013, the Company had notes receivable from Flash Forward of $169.1 million, denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Forward with the note proceeds. The Company also has guarantee obligations to Flash Forward; see “Off-Balance Sheet Liabilities.” At December 29, 2013 and December 30, 2012, the Company had an equity investment in Flash Forward of $66.7 million and $65.7 million, respectively, denominated in Japanese yen, offset by ($16.2) million and ($3.7) million, respectively, of cumulative translation adjustments recorded in AOCI.

	Inventory Purchase Commitments with Flash Ventures. Purchase orders placed under Flash Ventures for up to three months are binding and cannot be canceled. These outstanding purchase commitments are included as part of the total “Noncancelable production purchase commitments” in the “Contractual Obligations” table.

	Other Arrangements and Activities

	Research and Development Activities. The Company participates in common R&D activities with Toshiba and is contractually committed to a minimum funding level.

	Toshiba Foundry. In the first quarter of fiscal year 2013, the Company concluded its foundry arrangement with Toshiba.

	Other Silicon Sources. The Company’s contracts with its other sources of silicon wafers generally require the Company to provide monthly purchase order commitments. The purchase orders placed under these arrangements are generally binding and cannot be canceled. These outstanding purchase commitments for other sources of silicon wafers are included as part of the total “Noncancelable production purchase commitments” in the “Contractual Obligations” table.

	Subcontractors. In the normal course of business, the Company’s subcontractors periodically procure production materials based on the forecast the Company provides to them. The Company’s agreements with these subcontractors require that the Company reimburse them for materials that are purchased on the Company’s behalf in accordance with such forecast. Accordingly, the Company may be committed to certain costs over and above its open noncancelable purchase orders with these subcontractors. These commitments for production materials to subcontractors are included as part of the total “Noncancelable production purchase commitments” in the “Contractual Obligations” table.

	Off-Balance Sheet Liabilities

	Flash Ventures. The Flash Ventures sell and lease back from a consortium of financial institutions (“lessors”) a portion of their tools and have entered into equipment master lease agreements totaling 162.6 billion Japanese yen, or approximately $1.55 billion based upon the exchange rate at December 29, 2013. As of December 29, 2013, the total amount outstanding from these master leases was 103.2 billion Japanese yen, or approximately $983 million based upon the exchange rate at December 29, 2013, of which the amount of the Company’s guarantee obligation of the Flash Ventures’ master lease agreements, which reflects future payments and any lease adjustments, was 51.6 billion Japanese yen, or approximately $492 million based upon the exchange rate at December 29, 2013.

	The master lease agreements contain customary covenants for Japanese lease facilities. In addition to containing customary events of default related to Flash Ventures that could result in an acceleration of Flash Ventures’ obligations, the master lease agreements contain an acceleration clause for certain events of default related to the Company as guarantor, including, among other things, the Company’s failure to maintain a minimum stockholders’ equity of at least $1.51 billion. As of December 29, 2013, Flash Ventures was in compliance with all of its master lease covenants, including the shareholder equity covenant with our stockholders’ equity at $6.97 billion as of December 29, 2013. If the Company’s stockholders’ equity falls below $1.51 billion, or other events of default occur, Flash Ventures would become non-compliant under its master equipment lease agreements and would be required to negotiate a resolution to the non-compliance to avoid acceleration of the obligations under such agreements. Such resolution could include, among other things, supplementary security to be supplied by the Company, as guarantor, or increased interest rates or waiver fees, should the lessors decide they need additional collateral or financial consideration under the circumstances. If a non-compliance event were to occur and if the Company failed to reach a resolution, the Company could be required to pay a portion or the entire outstanding lease obligations covered by its guarantees under such Flash Ventures master lease agreements.


	The following table details the Company’s portion of the remaining guarantee obligations under each of Flash Ventures’ master lease facilities (both original and refinanced leases) in both Japanese yen (in billions) and U.S. dollar (in thousands) equivalent based upon the exchange rate at December 29, 2013.

Guarantees

Indemnification Agreements. The Company has agreed to indemnify suppliers and customers for alleged intellectual property 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 December 29, 2013, no amounts had been accrued in the accompanying Consolidated Financial Statements with respect to these indemnification guarantees.

As permitted under Delaware law and the Company’s certificate of incorporation and bylaws, the Company has agreements, or has assumed agreements in connection with its acquisitions, whereby it indemnifies certain of its officers and employees, and each of its directors for certain events or occurrences while the officer, employee or director is, or was, serving at the Company’s or the acquired company’s request in such capacity. The term of the indemnification period is for the officer’s, employee’s or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is generally 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 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 December 29, 2013 or December 30, 2012, as these liabilities are not reasonably estimable even though liabilities under these agreements are not remote.

The Company and Toshiba have agreed to mutually contribute to, and indemnify each other and Flash Ventures for, environmental remediation costs or liability resulting from Flash Ventures’ manufacturing operations in certain circumstances. 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 Ventures infringe third-party patents. The Company has not made any indemnification payments under any such agreements. As of December 29, 2013, no amounts have been accrued in the accompanying Consolidated Financial Statements with respect to these indemnification guarantees.

	Flash Ventures with Toshiba. The Company owns 49.9% of each entity within Flash Ventures and accounts for its ownership position under the equity method of accounting. The Company’s obligations with respect to the Flash Ventures master lease agreements, take-or-pay supply arrangements and R&D cost sharing are described in Note 12, “Commitments, Contingencies and Guarantees.” The financial and other support provided by the Company in all periods presented was either contractually required or the result of a joint decision to expand wafer capacity, transition to new technologies or refinance existing equipment lease commitments. Flash Ventures are variable interest entities (“VIEs”). The Company evaluated whether it is the primary beneficiary of any of the entities within Flash Ventures for all periods presented and determined that it is not the primary beneficiary of any of the entities within Flash Ventures because it does not have a controlling financial interest in any of those entities. In determining whether the Company is the primary beneficiary, the Company analyzed the primary purpose and design of Flash Ventures, the activities that most significantly impact Flash Ventures’ economic performance, and whether the Company had the power to direct those activities. The Company concluded based upon its 49.9% ownership in Flash Ventures, the voting structure of Flash Ventures and the manner in which the day-to-day operations of Flash Ventures are conducted that the Company lacked the power to direct most of the activities that most significantly impact Flash Ventures’ economic performance.

	The Company purchased NAND flash memory wafers from Flash Ventures and made prepayments, investments and loans to Flash Ventures totaling $1.87 billion, $2.71 billion and $2.95 billion during fiscal years 2013, 2012 and 2011, respectively. The Company received loan repayments from Flash Ventures of $124.8 million, $511.3 million and $416.3 million during fiscal years 2013, 2012 and 2011, respectively. At December 29, 2013 and December 30, 2012, the Company had accounts payable balances due to Flash Ventures of $146.0 million and $214.5 million, respectively.

	Stockholders’ Rights Plan

	On September 15, 2003, the Company amended its existing stockholder rights plan to terminate the rights issued under that rights plan, and the Company adopted a new rights plan. Under the new rights plan, rights were distributed as a dividend at the rate of one right for each share of common stock of the Company held by stockholders of record as of the close of business on September 25, 2003. In November 2006, the Company extended the term of the rights plan, such that the rights will expire on April 28, 2017 unless redeemed or exchanged. Under the new rights agreement and after giving effect to the Company’s stock dividend effected on February 18, 2004, each right will, under the circumstances described below, entitle the registered holder to buy one (1) two-hundredths of a share of Series A Junior Participating Preferred Stock for $225.00. The rights will become exercisable only if a person or group acquires beneficial ownership of 15% or more of the Company’s common stock or commences a tender offer or exchange offer upon consummation of which such person or group would beneficially own 15% or more of the Company’s common stock.

	SMART Storage Systems. On August 22, 2013, the Company completed its acquisition of SMART Storage, a developer of enterprise SSDs. The Company expects this acquisition to enhance its enterprise storage product portfolio. The Company acquired 100% of the outstanding shares of SMART Storage through an all-cash transaction. The total purchase price was comprised of the following (in thousands):


		Purchase Price
	Cash consideration	$	304,982

	Estimated fair value of replacement stock options related to pre-combination service	136

	Total purchase price	$	305,118


	The Company assumed all unvested outstanding SMART Storage stock options, which were converted into options to purchase an aggregate of 0.2 million shares of the Company’s common stock. The fair value of these unvested stock options was determined using the Black-Scholes-Merton valuation model. The Company records the fair value of unvested replacement stock options that relate to post-combination services as operating expense over the remaining service periods.

	Net Tangible Assets. The allocation of the SMART Storage purchase price to the tangible assets acquired and liabilities acquired as of August 22, 2013 is summarized below (in thousands):


		Acquired Tangible Assets and Liabilities
	Cash	$	804

	Accounts receivable, net	7,827

	Inventory	29,331

	Deferred taxes - current	921

	Other current assets	28,002

	Property and equipment	5,734

	Deferred taxes - non-current	3,338

	Other non-current assets	149

	Total assets	76,106


	Accounts payable	(11,746		)
	Other current liabilities	(34,538		)
	Non-current liabilities	(8,979		)
	Total liabilities	(55,263		)
	Net tangible assets	$	20,843


	An existing $25.5 million liability that SMART Storage owed SMART Holdings, (the “Seller”), was not settled prior to the closing of the acquisition of SMART Storage in accordance with the purchase agreement and remained outstanding as of December 29, 2013. The Seller is contractually obligated to refund $25.5 million of the purchase price for this unsettled liability. The purchase price refund receivable and unsettled liability are recorded gross in Other current assets and Other current liabilities of the acquired tangible assets and liabilities of SMART Storage, respectively, as the Company does not have the legal right to offset. The Company expects these amounts to be settled in the first quarter of fiscal year 2014.


	Purchase Price Allocation. The total purchase price was allocated to SMART Storage’s net tangible and intangible assets based upon their estimated fair values as of August 22, 2013. The excess purchase price over the value of the net tangible liabilities 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. These estimates include those related to the forecast used to value the intangible assets assumed, including the allocation of developed technology and IPR&D, and the fair value of inventory and obligations related to excess committed purchases. The purchase price allocation is preliminary and the measurement period is open pending final adjustments to the opening net assets acquired.

	The following table presents the allocation of the SMART Storage purchase price (in thousands):


		Purchase Price Allocation
	Net tangible assets	$	20,843

	Intangible assets:

	Developed technology	146,100

	Trademarks	8,500

	Customer relationships	7,600

In-process research and development	6,300

Total intangible assets	168,500

Goodwill	115,775

Total purchase price	$	305,118


The total weighted-average amortization period for finite-lived intangible assets is 3.9 years. The intangible assets are amortized on a straight-line basis over the period during which the economic benefits of the intangible assets are expected to be utilized. The goodwill resulted from expected synergies from the transaction, including the Company’s supply of NAND flash and complementary products, which will enhance the Company’s overall product portfolio. Goodwill is not deductible for tax purposes. The Company did not record a deferred tax liability due to certain tax incentives awarded by the Malaysian government.

Acquisition-related costs of $3.1 million during the fiscal year ended December 29, 2013 were related to legal, regulatory and accounting fees, and were expensed to General and administrative expense in the Consolidated Statement of Operations. SMART Storage’s prior period financial results are not considered material to the Company.

	Litigation

	From time-to-time, the Company is involved in various litigation matters, including those described below, among others. The litigation proceedings in which the Company is involved from time to time, may include matters such as intellectual property, antitrust, commercial, labor, class action, and insurance disputes. The semiconductor industry is characterized by significant litigation seeking to enforce patent and other intellectual property rights. The Company has enforced and likely will continue to enforce its own intellectual property rights through litigation and related proceedings.

	In each case listed below where the Company is the defendant, the Company intends to vigorously defend the action. At this time, the Company does not believe it is reasonably possible that losses related to the litigation described below have occurred beyond the amounts, if any, which have been accrued. However, legal discovery and litigation is highly unpredictable and future legal developments may cause current estimates to change in future periods.

	Patent Infringement Litigation With Round Rock Research LLC. On October 27, 2011, in response to infringement allegations by Round Rock Research LLC (“Round Rock”), the Company filed a lawsuit against Round Rock in the U.S. District Court for the Northern District of California. The lawsuit seeks a declaratory judgment that twelve Round Rock patents are invalid and/or not infringed by flash memory products sold by the Company. Round Rock has since withdrawn its allegations of infringement as to three of the patents. SanDisk has filed motions for summary judgment of invalidity directed at two additional Round Rock patents, and Round Rock has filed a motion for summary judgment as to certain affirmative defenses asserted by SanDisk to the counterclaims in this action. These motions are currently pending. Fact discovery has closed in the case. Expert discovery is underway and initial expert reports have been exchanged. Trial is currently scheduled to begin on August 11, 2014.

	On May 3, 2012, Round Rock filed an action in the U.S. District Court for the District of Delaware alleging that the Company infringed eleven patents, and subsequently filed an amended complaint alleging that SanDisk’s infringement was willful. The parties agreed to dismiss one patent from this Delaware lawsuit that was also being litigated in the California case described above. Discovery is underway. Trial is currently scheduled to begin on January 20, 2015.

	Ritz Camera Federal Antitrust Class Action. On June 25, 2010, Ritz Camera & Image, LLC (“Ritz”) filed a complaint in the U.S. District Court for the Northern District of California (the “District Court”), alleging that the Company violated federal antitrust law by conspiring to monopolize and monopolizing the market for flash memory products. The lawsuit captioned Ritz Camera & Image, LLC v. SanDisk Corporation, Inc. and Eliyahou Harari, purports to be on behalf of direct purchasers of flash memory products sold by the Company and joint ventures controlled by the Company from June 25, 2006 through the present. The complaint alleges that the Company created and maintained a monopoly by fraudulently obtaining patents and using them to restrain competition and by allegedly converting other patents for its competitive use. On February 24, 2011, the District Court issued an Order granting in part and denying in part the Company’s motion to dismiss which resulted in Dr. Harari being dismissed as a defendant. On September 19, 2011, the Company filed a petition for permission to file an interlocutory appeal in the U.S. Court of Appeals for the Federal Circuit (the “Federal Circuit”) for the portion of the District Court’s Order denying the Company’s motion to dismiss based on Ritz’s lack of standing to pursue Walker Process antitrust claims. On October 27, 2011, the District Court administratively closed the case pending the Federal Circuit’s ruling on the Company’s petition. On November 20, 2012, the Federal Circuit affirmed the District Court’s order denying SanDisk’s motion to dismiss. On December 2, 2012, the Federal Circuit issued its mandate returning the case to the District Court. Discovery is now open in the District Court. On February 20, 2013, Ritz filed a motion requesting that Albert Giuliano, the Chapter 7 Trustee of the Ritz bankruptcy estate, be substituted as the plaintiff in this case, which the District Court granted on July 5, 2013. On October 1, 2013, the District Court granted the Trustee’s motion for leave to file a third amended complaint, which adds CPM Electronics Inc. and E.S.E. Electronics, Inc. as named plaintiffs. On December 17, 2013, Ritz sought leave to file a fourth amended complaint, which would add a cause of action for attempted monopolization and add another named plaintiff.

	Samsung Federal Antitrust Action Against Panasonic and SD‑*3C.* On July 15, 2010, Samsung Electronics Co., Ltd. (“Samsung”) filed an action in the U.S. District Court for the Northern District of California (the “District Court”) alleging various claims against Panasonic Corporation and Panasonic Corporation of North America (collectively, “Panasonic”) and SD‑3C, LLC (“SD‑3C”) under federal antitrust law pursuant to Sections 1 and 2 of the Sherman Act, and under California antitrust and unfair competition laws relating to the licensing practices and operations of SD‑3C. The complaint seeks an injunction against collection of Secure Digital (“SD”) card royalties, treble damages, restitution, pre- and post-judgment interest, costs, and attorneys’ fees, as well as a declaration that Panasonic and SD‑3C engaged in patent misuse and that the patents subject to such alleged misuse should be held unenforceable. The Company is not named as a defendant in this case, but it established SD‑3C along with Panasonic and Toshiba, and the complaint includes various factual allegations concerning the Company. As a member of SD‑3C, the Company may be responsible for a portion of any monetary award. Other requested relief, including an injunction or declaration of patent misuse, could result in a loss of revenue to the Company. Defendants filed a motion to dismiss on September 24, 2010, and Samsung filed a First Amended Complaint (“FAC”) on October 14, 2010. On August 25, 2011, the District Court dismissed the patent misuse claim with prejudice, but gave Samsung leave to amend its other claims. On January 3, 2012, the District Court granted defendants’ motion to dismiss Samsung’s complaint without leave to amend. Samsung has appealed, dated January 25, 2012. The briefing on appeal is complete, and oral argument took place on December 5, 2013.

	Federal Antitrust Class Action Against SanDisk, et al. On March 15, 2011, a putative class action captioned Oliver v. SD‑3C LLC, et al was filed in the U.S. District Court for the Northern District of California (the “District Court”) on behalf of a nationwide class of indirect purchasers of SD cards alleging various claims against the Company, SD‑3C, Panasonic, Toshiba, and Toshiba America Electronic Components, Inc. under federal antitrust law pursuant to Section 1 of the Sherman Act, California antirust and unfair competition laws, and common law. The complaint seeks an injunction of the challenged conduct, dissolution of “the cooperation agreements, joint ventures and/or cross-licenses alleged herein,” treble damages, restitution, disgorgement, pre- and post-judgment interest, costs, and attorneys’ fees. Plaintiffs allege that the Company (along with the other members of SD‑3C) conspired to artificially inflate the royalty costs associated with manufacturing SD cards in violation of federal and California antitrust and unfair competition laws, which in turn allegedly caused plaintiffs to pay higher prices for SD cards. The allegations are similar to, and incorporate by reference the complaint in the Samsung Electronics Co., Ltd. v. Panasonic Corporation; Panasonic Corporation of North America; and SD‑3C LLC described above. On May 21, 2012, the District Court granted Defendants’ motion to dismiss the complaint with prejudice. Plaintiffs have appealed. Briefing on the appeal was completed on June 21, 2013. Oral argument took place on December 5, 2013.

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 29, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash Equivalents, Short and Long-Term Marketable Securities. Cash equivalents consist of short-term, highly liquid financial instruments with insignificant interest rate risk that are readily convertible to cash and have maturities of three months or less from the date of purchase. Marketable securities with original maturities greater than three months from purchase date and remaining maturities less than one year are classified as short-term marketable securities. Marketable securities with remaining maturities greater than one year as of the balance sheet date are classified as long-term marketable securities. Short and long-term fixed income investments consist of U.S. Treasury securities, U.S. government-sponsored agency securities, international government securities, corporate notes and bonds, municipal notes and bonds, asset-backed securities and mortgage-backed securities. The fair market value of cash equivalents at December 29, 2013 approximated their carrying value. Cost of securities sold is based on specific identification.

Organization and Nature of Operations	'
Organization and Nature of Operations	Organization and Nature of Operations. SanDisk Corporation (together with its subsidiaries, the “Company”) was incorporated in the State of Delaware on June 1, 1988. The Company designs, develops, markets and manufactures data storage solutions in a variety of form factors using its flash memory, controller and firmware technologies. The Company operates in one segment, flash memory storage products.
Basis of Presentation	'
Basis of Presentation	Basis of Presentation. The Company’s fiscal year ends on the Sunday closest to December 31. All fiscal years presented consisted of 52 weeks. Certain prior period amounts have been reclassified in the financial statements and footnotes to conform to the current period presentation, including line items within current assets and property and equipment in the Consolidated Balance Sheets and Note 4, “Balance Sheet Information,” as well as cash flows from operating activities in the Consolidated Statement of Cash Flows. Beginning in the first quarter of fiscal year 2013, the Company reports only total revenue, which includes product revenue and license and royalty revenue. For accounting and disclosure purposes, the exchange rate used to convert Japanese yen to the United States (“U.S.”) dollar for fiscal years ended December 29, 2013, December 30, 2012 and January 1, 2012 was 104.94, 85.99 and 77.17, respectively. Throughout the Notes to Consolidated Financial Statements, unless otherwise indicated, references to Net income refer to Net income attributable to common stockholders.
Consolidation, Policy	'
Consolidation, Policy	Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Non-controlling interest represents the minority shareholders’ proportionate share of the net assets and results of operations of the Company’s majority-owned subsidiaries. The Consolidated Financial Statements also include the results of companies acquired by the Company from the date of each acquisition.
Use of Estimates	'
Use of Estimates	Use of Estimates. The preparation of Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenue, expenses and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, intellectual property claims, product returns, allowance for doubtful accounts, inventories and inventory reserves, valuation and impairments of marketable securities and investments, valuation and impairments of goodwill and long-lived assets, income taxes, warranty obligations, restructurings, contingencies, share-based compensation and litigation. The Company bases its 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 value of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition, Sales Returns and Allowances and Sales Incentive Programs. The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title and acceptance, if applicable, pricing is fixed or determinable and collectability is reasonably assured. Revenue is generally recognized at the time of shipment or transfer of title for customers not eligible for price protection and/or a right of return. Sales made to distributors and retailers are generally under agreements allowing price protection and/or a right of return and, therefore, the revenue and related costs of these transactions are deferred until the retailers or distributors sell-through the merchandise to their end customer or their rights of return expire. Estimated sales returns are recorded as a reduction to revenue and deferred revenue and were not material for any period presented in the accompanying Consolidated Financial Statements. The cost of shipping products to customers is included in cost of revenue. The Company recognizes expenses related to sales commissions in the period in which the commissions are earned.

	For multiple element arrangements and revenue arrangements that include software elements, the Company allocates revenue to each element based on its relative selling price in accordance with the Company’s normal pricing and discounting practices for the specific product or maintenance when sold separately for all multiple element products. In addition, the Company analyzes whether tangible products containing software and non-software components that function together should be excluded from industry-specific software revenue recognition guidance. Multiple element arrangements and arrangements that include software have been immaterial to the Company’s revenue and operating results.

	Revenue from patent licensing arrangements is recognized when earned, estimable and realizable. The timing of revenue recognition is dependent on the terms of each license agreement and on the timing of sales of licensed products. The Company generally recognizes royalty revenue when it is reported to the Company by its licensees, which is generally one quarter in arrears from the licensees’ sales of licensed products. For licensing fees that are not determined by the number of licensed units sold, the Company recognizes license fee revenue on a straight-line basis over the life of the license.

	The Company records estimated reductions of revenue for customer and distributor incentive programs and offerings, including price protection, promotions, co-op advertising and other volume-based incentives and expected returns. All sales incentive programs are recorded as an offset to revenue or deferred revenue. Marketing development programs are recorded as a reduction to revenue.
Trade and Other Accounts Receivable, Policy [Policy Text Block]	'
	Accounts Receivable and Allowance for Doubtful Accounts. Accounts receivable include amounts owed by geographically dispersed distributors, retailers and original equipment manufacturer (“OEM”) customers. No collateral is required. Provisions are provided for sales returns and credit losses.

	The Company estimates the collectability of its accounts receivable based on a combination of factors, including but not limited to, customer credit ratings and historical experience. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations to the Company (e.g., bankruptcy filings or substantial downgrading of credit ratings), the Company provides allowances for bad debts against amounts due to reduce the net recognized receivable to the amount it reasonably believes will be collected.
Income Tax, Policy [Policy Text Block]	'
	Income Taxes. The Company accounts for income taxes using an asset and liability approach, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s Consolidated Financial Statements, but have not been reflected in the Company’s taxable income. The Company must evaluate the expected realization of its deferred tax assets and determine whether a valuation allowance needs to be established or released. In determining the need for and amount of a valuation allowance, the Company assesses the likelihood that it will be able to recover its deferred tax assets using historical levels of income, estimates of future income and tax planning strategies. A valuation allowance is established to the extent that the Company does not believe it is “more likely than not” that it will generate sufficient taxable income in future periods to realize the benefit of its deferred tax assets.

	The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company recognizes the tax benefit from an uncertain tax position only if it is “more likely than not” the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement.
Property, Plant and Equipment, Policy [Policy Text Block]	'
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment. Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, ranging from two to twenty-five years, or the remaining lease term, whichever is shorter.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	'
	Variable Interest Entities. The Company evaluates its equity method investments to determine whether any investee is a variable interest entity (“VIE”). If the Company concludes that an investee is a VIE, the Company evaluates its power to direct the activities of the investee, its obligation to absorb the expected losses of the investee and its right to receive the expected residual returns of the investee to determine whether the Company is the primary beneficiary of the investee. If the Company is the primary beneficiary of a VIE, the Company consolidates such entity and reflects the non-controlling interest of other beneficiaries of that entity. If the Company concludes that an investee is not a VIE, the Company does not consolidate the investee.
Equity Method Investments, Policy [Policy Text Block]	'
	Equity Investments. The Company accounts for investments in equity securities of other entities, including VIEs that are not consolidated, under the cost method of accounting if investments in voting equity interests of the investee are less than 20%. The equity method of accounting is used if the Company’s investment in voting stock is greater than or equal to 20% but less than a majority. In considering the accounting method for investments less than 20%, the Company also considers other factors such as its ability to exercise significant influence over operating and financial policies of the investee. If certain factors are present, the Company could account for investments for which it has less than a 20% ownership under the equity method of accounting.

	Investments in public companies with restrictions of less than one year are classified as available-for-sale and are adjusted to their fair market value with unrealized gains and losses recorded as a component of accumulated other comprehensive income (“AOCI”). Investments in public and non-public companies are reviewed on a quarterly basis to determine if their value has been impaired and adjustments are recorded as necessary. Upon disposition of these investments, the specific identification method is used to determine the cost basis in computing realized gains or losses. Declines in value that are judged to be other-than-temporary are reported in Interest (expense) and other income (expense), net or Cost of revenue in the accompanying Consolidated Statements of Operations.
Inventory, Policy [Policy Text Block]	'
	Inventories and Inventory Valuation. Inventories are stated at the lower of cost (first-in, first-out) or market. Market value is based upon an estimated average selling price reduced by estimated costs of disposal. Should actual market conditions differ from the Company’s estimates, the Company’s future results of operations could be materially affected. Reductions in inventory valuation are included in Cost of revenue in the accompanying Consolidated Statements of Operations. Inventory impairment charges, when taken, permanently establish a new cost basis and are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable. Rather, these amounts are recognized in income only if, as and when the inventory is sold.

	The Company reduces the carrying value of its inventory to a new basis for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of the inventory and the estimated market value based upon assumptions about future demand and market conditions, including assumptions about changes in average selling prices. If actual market conditions are less favorable than those projected by management, additional reductions in inventory valuation may be required.

	The Company’s finished goods inventory includes consigned inventory held at customer locations as well as at third-party fulfillment centers and subcontractors.
Goodwill and Intangible Assets, Policy [Policy Text Block]	'
Goodwill and Intangible Assets, Policy [Policy Text Block]	Other Long-Lived Assets. Intangible assets with finite useful lives and other long-lived assets are tested for impairment if certain impairment indicators are identified. The Company assesses the carrying value of long-lived assets, whenever events or changes in circumstances indicate that the carrying value of these long-lived assets may not be recoverable. Factors the Company considers important which could result in an impairment review include: (1) significant under-performance relative to the historical or projected future operating results; (2) significant changes in the manner of use of assets; (3) significant negative industry or economic trends; and (4) significant changes in the Company’s market capitalization relative to net book value. Any changes in key assumptions used by the Company, including those set forth above, could result in an impairment charge and such a charge could have a material adverse effect on the Company’s consolidated results of operations.
Advertising Costs, Policy [Policy Text Block]	'
Advertising Costs, Policy [Policy Text Block]	Advertising Expenses. Marketing co-op development programs, where the Company receives, or will receive, an identifiable benefit (e.g., goods or services) in exchange for the amount paid to its customer and the Company can reasonably estimate the fair value of the benefit it receives for the customer incentive payment, are classified, when granted, as a marketing expense. Advertising expenses not meeting this criteria are classified as a reduction to revenue when the expense is incurred. Advertising expenses recorded as marketing expense were $19.6 million, $16.2 million and $11.4 million in fiscal years 2013, 2012 and 2011, respectively.
Research and Development Expense, Policy [Policy Text Block]	'
	Research and Development Expenses. Research and development (“R&D”) expenditures are expensed as incurred.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	'
	Foreign Currency. The Company determines the functional currency for its parent company and each of its subsidiaries by reviewing the currencies in which their respective operating activities occur. Transaction gains and losses arising from activities in other than the applicable functional currency are calculated using average exchange rates for the applicable period and reported in net income as a non-operating item in each period. Non-monetary balance sheet items denominated in a currency other than the applicable functional currency are translated using the historical rate. The Company continuously evaluates its foreign currency exposures and may continue to enter into hedges or other risk mitigating arrangements in the future. Aggregate gross foreign currency transaction gain (loss) prior to consideration of the offsetting hedges recorded to income before taxes was ($3.3) million, ($2.8) million and $18.8 million in fiscal years 2013, 2012 and 2011, respectively.

Investments and Fair Value Measurements Investments and Fair Value Measurements (Policies)	12 Months Ended
	Dec. 29, 2013
Fair Value Of Financial Instruments Policy [Abstract]	'
Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	The Company categorizes the fair value of its financial assets and liabilities according to the hierarchy established by the FASB, which prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are:


	Level 1	Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to directly access.
	Level 2	Valuations based on quoted prices for similar assets or liabilities; valuations for interest-bearing securities based on non-daily quoted prices in active markets; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
	Level 3	Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

	A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

	In circumstances in which a quoted price in an active market for the identical liability is not available, the Company is required to use the quoted price of the identical liability when traded as an asset, quoted prices for similar liabilities, or quoted prices for similar liabilities when traded as assets. If these quoted prices are not available, the Company is required to use another valuation technique, such as an income approach or a market approach.

Investments, Debt and Equity Securities [Abstract]	'
Derivatives, Policy [Policy Text Block]	'
Derivatives, Policy [Policy Text Block]	The Company recognizes derivative instruments as either assets or liabilities on the balance sheet at fair value and provides qualitative disclosures about objectives and strategies for using derivative instruments, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. Changes in fair value (i.e., gains or losses) of the derivatives are recorded as cost of revenue or other income (expense), or as other comprehensive income (“OCI”). The Company does not offset or net the fair value amounts of derivative instruments and separately discloses the fair value amounts of the derivative instruments as either assets or liabilities.
