Note 1 – Summary of Significant Accounting Policies

Apple Inc. and its wholly-owned subsidiaries (collectively “Apple” or the “Company”) designs, manufactures, and markets personal computers, mobile communication and media devices, and portable digital music players, and sells a variety of related software, services, peripherals, networking solutions, and third-party digital content and applications. The Company sells its products worldwide through its retail stores, online stores, and direct sales force, and third-party cellular network carriers, wholesalers, resellers and value-added resellers. In addition, the Company sells a variety of third-party Macintosh (“Mac”), iPhone, iPad and iPod compatible products including application software, printers, storage devices, speakers, headphones, and various other accessories and supplies through its online and retail stores. The Company sells to consumer, small and mid-sized business, education, enterprise, government and creative customers.

Basis of Presentation and Preparation

The accompanying consolidated financial statements include the accounts of the Company. Intercompany accounts and transactions have been eliminated. The preparation of these 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 these consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Certain prior year amounts in the consolidated financial statements and notes thereto have been reclassified to conform to the current year’s presentation.

The Company’s fiscal year is the 52 or 53-week period that ends on the last Saturday of September. The Company’s fiscal years 2010, 2009 and 2008 ended on September 25, 2010, September 26, 2009 and September 27, 2008, respectively, and included 52 weeks each. An additional week is included in the first fiscal quarter approximately every six years to realign fiscal quarters with calendar quarters. Unless otherwise stated, references to particular years or quarters refer to the Company’s fiscal years ended in September and the associated quarters of those fiscal years.

Retrospective Adoption of New Accounting Principles

In September 2009, the Financial Accounting Standards Board (“FASB”) amended the accounting standards related to revenue recognition for arrangements with multiple deliverables and arrangements that include software elements (“new accounting principles”). The new accounting principles permitted prospective or retrospective adoption, and the Company elected retrospective adoption during the first quarter of 2010.

Under the historical accounting principles, the Company was required to account for sales of both iPhone and Apple TV using subscription accounting because the Company indicated it might from time-to-time provide future unspecified software upgrades and features for those products free of charge. Under subscription accounting, revenue and associated product cost of sales for iPhone and Apple TV were deferred at the time of sale and recognized on a straight-line basis over each product’s estimated economic life. This resulted in the deferral of significant amounts of revenue and cost of sales related to iPhone and Apple TV.

The new accounting principles affect the Company’s accounting for all past and current sales of iPhone, iPad, Apple TV and for sales of iPod touch beginning in June 2010. The new accounting principles require the Company to account for the sale of these devices as two deliverables. The first deliverable is the hardware and software essential to the functionality of the hardware device delivered at the time of sale, and the second deliverable is the right included with the purchase of these devices to receive on a when-and-if-available basis, future unspecified software upgrades and features relating to the product’s essential software. The new accounting principles result in the recognition of a substantial portion of the revenue and all product costs from the sale of these devices at the time of their sale. Additionally, the Company is required to estimate a standalone selling price for the unspecified software upgrade rights included with the sale of these devices and recognizes that amount ratably over the 24-month estimated life of the related hardware device.

Refer to the “Explanatory Note” and Note 2, “Retrospective Adoption of New Accounting Principles” in the 2009 Form 10-K for additional information on the impact of adoption of the new accounting principles, which sections are incorporated herein by reference.

Revenue Recognition

Net sales consist primarily of revenue from the sale of hardware, software, digital content and applications, peripherals, and service and support contracts. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collection is probable. Product is considered delivered to the customer once it has been shipped and title and risk of loss have been transferred. For most of the Company’s product sales, these criteria are met at the time the product is shipped. For online sales to individuals, for some sales to education customers in the U.S., and for certain other sales, the Company defers revenue until the customer receives the product because the Company legally retains a portion of the risk of loss on these sales during transit. The Company recognizes revenue from the sale of hardware products (e.g., Macs, iPhones, iPads, iPods and peripherals), software bundled with hardware that is essential to the functionality of the hardware, and third-party digital content sold on the iTunes Store in accordance with general revenue recognition accounting guidance. The Company recognizes revenue in accordance with industry specific software accounting guidance for the following types of sales transactions: (i) standalone sales of software products, (ii) sales of software upgrades and (iii) sales of software bundled with hardware not essential to the functionality of the hardware.

The Company sells software and peripheral products obtained from other companies. The Company generally establishes its own pricing and retains related inventory risk, is the primary obligor in sales transactions with its customers, and assumes the credit risk for amounts billed to its customers. Accordingly, the Company generally recognizes revenue for the sale of products obtained from other companies based on the gross amount billed. For certain sales made through the iTunes Store, including sales of third-party software applications for the Company’s iOS devices, the Company is not the primary obligor to users of the software, and third-party developers determine the selling price of their software. Therefore, the Company accounts for such sales on a net basis by recognizing only the commission it retains from each sale and including that commission in net sales in the Consolidated Statements of Operations. The portion of the sales price paid by users that is remitted by the Company to third-party developers is not reflected in the Company’s Consolidated Statement of Operations.

The Company records deferred revenue when it receives payments in advance of the delivery of products or the performance of services. This includes amounts that have been deferred related to embedded unspecified and specified software upgrades rights. The Company sells gift cards redeemable at its retail and online stores, and also sells gift cards redeemable on the iTunes Store for the purchase of content and software. The Company records deferred revenue upon the sale of the card, which is relieved upon redemption of the card by the customer. Revenue from AppleCare service and support contracts is deferred and recognized ratably over the service coverage periods. AppleCare service and support contracts typically include extended phone support, repair services, web-based support resources and diagnostic tools offered under the Company’s standard limited warranty.

The Company records reductions to revenue for estimated commitments related to price protection and for customer incentive programs, including reseller and end-user rebates, and other sales programs and volume-based incentives. The estimated cost of these programs is recognized in the period the Company has sold the product and committed to a plan. The Company also records reductions to revenue for expected future product returns based on the Company’s historical experience. Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.

Revenue Recognition for Arrangements with Multiple Deliverables

For multi-element arrangements that include tangible products that contain software that is essential to the tangible product’s functionality and undelivered software elements that relate to the tangible product’s essential software, the Company allocates revenue to all deliverables based on their relative selling prices. In such circumstances, the Company uses a hierarchy to determine the selling price to be used for allocating revenue to deliverables: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of the selling price (“ESP”). VSOE generally exists only when the Company sells the deliverable separately and is the price actually charged by the Company for that deliverable. ESPs reflect the Company’s best estimates of what the selling prices of elements would be if they were sold regularly on a stand-alone basis.

As described in more detail below, for all past and current sales of iPhone, iPad, Apple TV and for sales of iPod touch beginning in June 2010, the Company has indicated it may from time-to-time provide future unspecified software upgrades and features free of charge to customers. The Company has identified two deliverables in arrangements involving the sale of these devices. The first deliverable is the hardware and software essential to the functionality of the hardware device delivered at the time of sale. The second deliverable is the embedded right included with the purchase of iPhone, iPad, iPod touch and Apple TV to receive on a when-and-if-available basis, future unspecified software upgrades and features relating to the product’s essential software. The Company has allocated revenue between these two deliverables using the relative selling price method. Because the Company has neither VSOE nor TPE for the two deliverables, the allocation of revenue has been based on the Company’s ESPs. Amounts allocated to the delivered hardware and the related essential software are recognized at the time of sale provided the other conditions for revenue recognition have been met. Amounts allocated to the embedded unspecified software upgrade rights are deferred and recognized on a straight-line basis over the 24-month estimated life of each of these devices. All product cost of sales, including estimated warranty costs, are recognized at the time of sale. Costs for engineering and sales and marketing are expensed as incurred.

The Company’s process for determining its ESP for deliverables without VSOE or TPE considers multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. The Company believes its customers, particularly consumers, would be reluctant to buy unspecified software upgrade rights related to iPhone, iPad, iPod touch and Apple TV. This view is primarily based on the fact that unspecified upgrade rights do not obligate the Company to provide upgrades at a particular time or at all, and do not specify to customers which upgrades or features will be delivered. Therefore, the Company has concluded that if it were to sell upgrade rights on a standalone basis, including those rights associated with iPhone, iPad, iPod touch and Apple TV, the selling price would be relatively low. Key factors considered by the Company in developing the ESPs for these upgrade rights include prices charged by the Company for similar offerings, the Company’s historical pricing practices, the nature of the upgrade rights (e.g., unspecified and when-and-if-available), and the relative ESP of the upgrade rights as compared to the total selling price of the product. The Company may also consider, when appropriate, the impact of other products and services, including advertising services, on selling price assumptions when developing and reviewing its ESPs for software upgrade rights and related deliverables. The Company may also consider additional factors as appropriate, including the pricing of competitive alternatives if they exist, and product-specific business objectives.

Beginning in the third quarter of 2010 in conjunction with the announcement of iOS 4, the Company’s ESPs for the embedded software upgrade rights included with iPhone, iPad and iPod touch reflect the positive financial impact expected by the Company as a result of its introduction of a mobile advertising platform for these devices and the expectation of customers regarding software that includes or supports an advertising component. iOS 4 supports iAd, the Company’s new mobile advertising platform, which enables applications on iPhone, iPad and iPod touch to embed media-rich advertisements.

For all periods presented, the Company’s ESP for the embedded software upgrade right included with each Apple TV sold is $10. The Company’s ESP for the software upgrade right included with each iPhone sold through the Company’s second quarter of 2010 was $25. Beginning in April 2010 in conjunction with the Company’s announcement of iOS 4 for iPhone, the Company lowered its ESP for the software upgrade right included with each iPhone to $10.

Beginning with initial sales of iPad in April 2010, the Company has also indicated it may from time-to-time provide future unspecified software upgrades and features free of charge to iPad customers. The Company’s ESP for the embedded software upgrade right included with the sale of each iPad is $10. In June 2010, the Company announced that certain previously sold iPod touch models would receive an upgrade to iOS 4 free of charge and indicated iPod touch devices running on iOS 4 may from time-to-time receive future unspecified software upgrades and features free of charge. The Company’s ESP for the embedded software upgrade right included with each iPod touch sold beginning in June 2010 is $5.

The Company accounts for multiple element arrangements that consist only of software or software-related products, including the sale of upgrades to previously sold software, in accordance with industry specific accounting guidance for software and software-related transactions. For such transactions, revenue on arrangements that include multiple elements is allocated to each element based on the relative fair value of each element, and fair value is determined by VSOE. If the Company cannot objectively determine the fair value of any undelivered element included in such multiple-element arrangements, the Company defers revenue until all elements are delivered and services have been performed, or until fair value can objectively be determined for any remaining undelivered elements. When the fair value of a delivered element has not been established, but fair value exists for the undelivered elements, the Company uses the residual method to recognize revenue. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is allocated to the delivered elements and is recognized as revenue.

Except as described for iPhone, iPad, iPod touch and Apple TV, the Company generally does not offer unspecified upgrade rights to its customers in connection with software sales or the sale of AppleCare extended warranty and support contracts. A limited number of the Company’s software products are available with maintenance agreements that grant customers rights to unspecified future upgrades over the maintenance term on a when and if available basis. Revenue associated with such maintenance is recognized ratably over the maintenance term.

Shipping Costs

For all periods presented, amounts billed to customers related to shipping and handling are classified as revenue, and the Company’s shipping and handling costs are included in cost of sales.

Warranty Expense

The Company generally provides for the estimated cost of hardware and software warranties at the time the related revenue is recognized. The Company assesses the adequacy of its pre-existing warranty liabilities and adjusts the amounts as necessary based on actual experience and changes in future estimates.

Software Development Costs

Research and development costs are expensed as incurred. Development costs of computer software to be sold, leased, or otherwise marketed are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. In most instances, the Company’s products are released soon after technological feasibility has been established. Therefore, costs incurred subsequent to achievement of technological feasibility are usually not significant, and generally most software development costs have been expensed as incurred.

The Company did not capitalize any software development costs during 2010. In 2009 and 2008, the Company capitalized $71 million and $11 million, respectively, of costs associated with the development of Mac OS X Version 10.6 Snow Leopard (“Mac OS X Snow Leopard”), which was released during the fourth quarter of 2009. The capitalized costs are being amortized to cost of sales on a straight-line basis over a three year estimated useful life of the underlying technology.

Total amortization related to capitalized software development costs was $48 million, $25 million and $27 million in 2010, 2009 and 2008, respectively.

Advertising Costs

Advertising costs are expensed as incurred. Advertising expense was $691 million, $501 million and $486 million for 2010, 2009 and 2008, respectively.

Stock-Based Compensation

The Company accounts for stock-based payment transactions in which the Company receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise’s equity instruments or that may be settled by the issuance of such equity instruments. Stock-based compensation cost for restricted stock units (“RSUs”) is measured based on the closing fair market value of the Company’s common stock on the date of grant. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes-Merton (“BSM”) option-pricing model. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period. The Company will recognize a benefit from stock-based compensation in equity if an incremental tax benefit is realized by following the ordering provisions of the tax law. In addition, the Company accounts for the indirect effects of stock-based compensation on the research tax credit, the foreign tax credit and the domestic manufacturing deduction through the income statement. Further information regarding stock-based compensation can be found in Note 7, “Shareholders’ Equity and Stock-Based Compensation” of this Form 10-K.

Income Taxes

The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized.

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. See Note 6, “Income Taxes” of this Form 10-K for additional information.

Earnings Per Common Share

Basic earnings per common share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the employee stock purchase plan and unvested RSUs. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per common share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities.

The following table sets forth the computation of basic and diluted earnings per common share for the three years ended September 25, 2010 (in thousands, except net income in millions and per share amounts):

Potentially dilutive securities representing 1.6 million, 12.6 million and 10.3 million shares of common stock for 2010, 2009 and 2008, respectively, were excluded from the computation of diluted earnings per common share for these periods because their effect would have been antidilutive.

Financial Instruments

Cash Equivalents and Marketable Securities

All highly liquid investments with maturities of three months or less at the date of purchase are classified as cash equivalents. The Company’s debt and marketable equity securities have been classified and accounted for as available-for-sale. Management determines the appropriate classification of its investments in debt securities at the time of purchase and reevaluates the available-for-sale designations as of each balance sheet date. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Marketable securities with maturities of less than 12 months are classified as short-term and marketable securities with maturities greater than 12 months are classified as long-term. These securities are carried at fair value, with the unrealized gains and losses, net of taxes, reported as a component of shareholders’ equity. The cost of securities sold is based upon the specific identification method.

Derivative Financial Instruments

The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. Derivatives that are not defined as hedges must be adjusted to fair value through earnings.

For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income in shareholders’ equity and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in current earnings. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. For options designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in earnings. For derivative instruments that hedge the exposure to changes in the fair value of an asset or a liability and that are designated as fair value hedges, the net gain or loss on the derivative instrument as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings in the current period. The Company did not have a net gain or loss on these derivative instruments during 2010, 2009 and 2008. The net gain or loss on the effective portion of a derivative instrument that is designated as an economic hedge of the foreign currency translation exposure of the net investment in a foreign operation is reported in the same manner as a foreign currency translation adjustment. For forward exchange contracts designated as net investment hedges, the Company excludes changes in fair value relating to changes in the forward carry component from its definition of effectiveness. Accordingly, any gains or losses related to this component are recognized in current earnings.

Allowance for Doubtful Accounts

The Company records its allowance for doubtful accounts based upon its assessment of various factors. The Company considers historical experience, the age of the accounts receivable balances, credit quality of the Company’s customers, current economic conditions, and other factors that may affect customers’ ability to pay.

Inventories

Inventories are stated at the lower of cost, computed using the first-in, first-out method, or market. If the cost of the inventories exceeds their market value, provisions are made currently for the difference between the cost and the market value. The Company’s inventories consist primarily of components and finished goods for all periods presented.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is computed by use of the straight-line method over the estimated useful lives of the assets, which for buildings is the lesser of 30 years or the remaining life of the underlying building, up to five years for equipment, and the shorter of lease terms or ten years for leasehold improvements. The Company capitalizes eligible costs to acquire or develop internal-use software that are incurred subsequent to the preliminary project stage. Capitalized costs related to internal-use software are amortized using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Depreciation and amortization expense on property and equipment was $815 million, $606 million and $387 million during 2010, 2009 and 2008, respectively.

Long-Lived Assets Including Goodwill and Other Acquired Intangible Assets

The Company reviews property, plant and equipment and certain identifiable intangibles, excluding goodwill, for impairment. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparison of their carrying amounts to future undiscounted cash flows the assets are expected to generate. If property, plant and equipment and certain identifiable intangibles are considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the assets exceeds its fair market value. The Company did not record any significant impairments during 2010, 2009 and 2008.

The Company does not amortize goodwill and intangible assets with indefinite useful lives, rather such assets are required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired. The Company performs its goodwill and intangible asset impairment tests on or about August 31 of each year. The Company did not recognize any goodwill or intangible asset impairment charges in 2010, 2009 and 2008. The Company established reporting units based on its current reporting structure. For purposes of testing goodwill for impairment, goodwill has been allocated to these reporting units to the extent it relates to each reporting unit.

The Company amortizes its intangible assets with definite lives over their estimated useful lives and reviews these assets for impairment. The Company is currently amortizing its acquired intangible assets with definite lives over periods ranging from three to ten years.

Fair Value Measurements

During 2009, the Company adopted the FASB’s new accounting standard on fair value measurements and disclosures for all financial assets and liabilities. The new accounting principles define fair value, provide a framework for measuring fair value, and expand the disclosures required for fair value measurements. During the first quarter of 2010, the Company adopted the new fair value accounting principles for all non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis, which did not have a material effect on the Company’s financial condition or operating results.

The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. In accordance with the fair value accounting requirements, companies may choose to measure eligible financial instruments and certain other items at fair value. The Company has not elected the fair value option for any eligible financial instruments.

Foreign Currency Translation and Remeasurement

The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Revenue and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are credited or charged to foreign currency translation included in accumulated other comprehensive income in shareholders’ equity. The Company’s subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, and inventories, property, and nonmonetary assets and liabilities at historical rates. Gains and losses from these remeasurements were insignificant and have been included in the Company’s results of operations.

Segment Information

The Company reports segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Company’s reportable segments. Information about the Company’s products, major customers and geographic areas on a company-wide basis is also disclosed.

Business Combinations

In December 2007, the FASB issued a new accounting standard for business combinations, which established principles and requirements for how an acquirer is to recognize and measure in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree in a business combination. This new accounting standard also established principles regarding how goodwill acquired in a business combination or a gain from a bargain purchase should be recognized and measured, requiring the capitalization of in-process research and development at fair value and the expensing of acquisition-related costs as incurred, as well as providing guidelines on the disclosure requirements. In April 2009, the FASB amended this new accounting standard to require that assets acquired and liabilities assumed in a business combination that arise from contingencies be recognized at fair value, if the fair value can be determined during the measurement period. The Company adopted the new business combination accounting standard in the first quarter of 2010 and applied these principles to any business combinations completed in or after the first quarter of 2010. The adoption of the new business combination accounting standard did not have a material effect on the Company’s financial condition or operating results.

Note 2 – Financial Instruments

Cash, Cash Equivalents and Marketable Securities

The following table summarizes the fair value of the Company’s cash and available-for-sale securities held in its marketable securities investment portfolio, recorded as cash and cash equivalents or short-term or long-term marketable securities as of September 25, 2010 and September 26, 2009 (in millions):

The following tables summarize the Company’s available-for-sale securities’ adjusted cost, gross unrealized gains, gross unrealized losses and fair value by significant investment category as of September 25, 2010 and September 26, 2009 (in millions):

The Company had net unrealized gains on its investment portfolio of $180 million and $57 million as of September 25, 2010 and September 26, 2009, respectively. The net unrealized gains as of September 25, 2010 and September 26, 2009 related primarily to long-term marketable securities. The Company may sell certain of its marketable securities prior to their stated maturities for strategic purposes, in anticipation of credit deterioration, or for duration management. The Company recognized no significant net realized gains or losses during 2010, 2009 and 2008 related to such sales. The maturities of the Company’s long-term marketable securities generally range from one year to five years.

The following tables show the gross unrealized losses and fair value for investments in an unrealized loss position as of September 25, 2010 and September 26, 2009, aggregated by investment category and the length of time that individual securities have been in a continuous loss position (in millions):

The Company considers the declines in market value of its marketable securities investment portfolio to be temporary in nature. The unrealized losses on the Company’s marketable securities were caused primarily by changes in market interest rates or widening credit spreads. The Company typically invests in highly-rated securities, and its policy generally limits the amount of credit exposure to any one issuer. The Company’s investment policy requires investments to be investment grade, primarily rated single-A or better, with the objective of minimizing the potential risk of principal loss. Fair values were determined for each individual security in the investment portfolio. When evaluating the investments for other-than-temporary impairment, the Company reviews factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer and any changes thereto, and the Company’s intent to sell, or whether it is more likely than not it will be required to sell, the investment before recovery of the investment’s amortized cost basis. During the years ended September 25, 2010 and September 26, 2009, the Company did not recognize any significant impairment charges. As of September 25, 2010, the Company does not consider any of its investments to be other-than-temporarily impaired.

Derivative Financial Instruments

The Company uses derivatives to partially offset its business exposure to foreign currency exchange risk. The Company may enter into foreign currency forward and option contracts to offset some of the foreign exchange risk of expected future cash flows on certain forecasted revenue and cost of sales, of net investments in certain foreign subsidiaries, and on certain existing assets and liabilities. To help protect gross margins from fluctuations in foreign currency exchange rates, certain of the Company’s subsidiaries whose functional currency is the U.S. dollar, hedge a portion of forecasted foreign currency revenue. The Company’s subsidiaries whose functional currency is not the U.S. dollar and who sell in local currencies, may hedge a portion of forecasted inventory purchases not denominated in the subsidiaries’ functional currencies. The Company typically hedges portions of its forecasted foreign currency exposure associated with revenue and inventory purchases for three to six months. To help protect the net investment in a foreign operation from adverse changes in foreign currency exchange rates, the Company may enter into foreign currency forward and option contracts to offset the changes in the carrying amounts of these investments due to fluctuations in foreign currency exchange rates. The Company may also enter into foreign currency forward and option contracts to partially offset the foreign currency exchange gains and losses generated by the re-measurement of certain assets and liabilities denominated in non-functional currencies. However, the Company may choose not to hedge certain foreign currency exchange exposures for a variety of reasons, including but not limited to immateriality, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange rates.

The Company’s accounting policies for these instruments are based on whether the instruments are designated as hedge or non-hedge instruments. The Company records all derivatives on the Consolidated Balance Sheets at fair value. The effective portions of cash flow hedges are recorded in other comprehensive income until the hedged item is recognized in earnings. The effective portions of net investment hedges are recorded in other comprehensive income as a part of the cumulative translation adjustment. Derivatives that are not designated as hedging instruments and the ineffective portions of cash flow hedges and net investment hedges are adjusted to fair value through earnings in other income and expense.

The Company had a net deferred loss associated with cash flow hedges of approximately $252 million and a net deferred gain of $1 million, net of taxes, recorded in other comprehensive income as of September 25, 2010 and September 26, 2009, respectively. Other comprehensive income associated with cash flow hedges of foreign currency revenue is recognized as a component of net sales in the same period as the related revenue is recognized, and other comprehensive income related to cash flow hedges of inventory purchases is recognized as a component of cost of sales in the same period as the related costs are recognized. Substantially all of the Company’s hedged transactions as of September 25, 2010 are expected to occur within six months.

Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur in the initially identified time period or within a subsequent two month time period. Deferred gains and losses in other comprehensive income associated with such derivative instruments are reclassified immediately into earnings through other income and expense. Any subsequent changes in fair value of such derivative instruments also are reflected in current earnings unless they are re-designated as hedges of other transactions. The Company did not recognize any significant net gains or losses related to the loss of hedge designation on discontinued cash flow hedges during 2010, 2009 and 2008.

The Company had an unrealized net loss on net investment hedges of $9 million and $2 million, net of taxes, included in the cumulative translation adjustment account of accumulated other comprehensive income (“AOCI”) as of September 25, 2010 and September 26, 2009, respectively. The ineffective portions and amounts excluded from the effectiveness test of net investment hedges are recorded in current earnings in other income and expense.

The Company recognized in earnings a net loss of $123 million and $133 million on foreign currency forward and option contracts not designated as hedging instruments during the year ended September 25, 2010 and September 26, 2009, respectively. These amounts represent the net gain or loss on the derivative contracts and do not include changes in the related exposures, which generally offset a portion of the gain or loss on the derivative contracts.

The following table shows the notional principal and credit risk amounts of the Company’s derivative instruments outstanding as of September 25, 2010 and September 26, 2009 (in millions):

The notional principal amounts for derivative instruments provide one measure of the transaction volume outstanding and does not represent the amount of the Company’s exposure to credit or market loss. The credit risk amounts represent the Company’s gross exposure to potential accounting loss on these transactions if all counterparties failed to perform according to the terms of the contract, based on then-current currency exchange rates at each respective date. The Company’s gross exposure on these transactions may be further mitigated by collateral received from certain counterparties. The Company’s exposure to credit loss and market risk will vary over time as a function of currency exchange rates. Although the table above reflects the notional principal and credit risk amounts of the Company’s foreign exchange instruments, it does not reflect the gains or losses associated with the exposures and transactions that the foreign exchange instruments are intended to hedge. The amounts ultimately realized upon settlement of these financial instruments, together with the gains and losses on the underlying exposures, will depend on actual market conditions during the remaining life of the instruments.

The Company generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. To further limit credit risk, the Company generally enters into collateral security arrangements that provide for collateral to be received or posted when the net fair value of certain financial instruments fluctuate from contractually established thresholds. The Company presents its derivative assets and derivative liabilities at their gross fair values. As of September 25, 2010, the Company has posted cash collateral related to the derivative instruments under its collateral security arrangements of $445 million and recorded the offsetting balance as other current assets in the Consolidated Balance Sheet. The Company did not record any significant amounts of cash collateral related to the derivative instruments under its master netting arrangements as of September 26, 2009. The Company did not have any derivative instruments with credit risk-related contingent features that would require it to post additional collateral as of September 25, 2010 or September 26, 2009.

The estimates of fair value are based on applicable and commonly used pricing models and prevailing financial market information as of September 25, 2010. Refer to Note 3, “Fair Value Measurements” of this Form 10-K, for additional information on the fair value measurements for all financial assets and liabilities, including derivative assets and derivative liabilities, that are measured at fair value in the consolidated financial statements on a recurring basis. The following tables show the Company’s derivative instruments measured at gross fair value as reflected in the Consolidated Balance Sheets as of September 25, 2010 and September 26, 2009 (in millions):

Accounts Receivable

Trade Receivables

The Company distributes its products through third-party cellular network carriers, wholesalers, retailers and value-added resellers and directly to certain education, consumer and enterprise customers. The Company generally does not require collateral from its customers; however, the Company will require collateral in certain instances to limit credit risk. In addition, when possible, the Company attempts to limit credit risk on trade receivables with credit insurance for certain customers in Latin America, Europe, Asia, and Australia, or by requiring third-party financing, loans or leases to support credit exposure. These credit-financing arrangements are directly between the third-party financing company and the end customer. As such, the Company generally does not assume any recourse or credit risk sharing related to any of these arrangements. However, considerable trade receivables not covered by collateral, third-party financing arrangements, or credit insurance are outstanding with the Company’s third-party cellular network carriers, wholesalers, retailers and value-added resellers. Trade receivables from two of the Company’s customers accounted for 15% and 12% of trade receivables as of September 25, 2010 and one of the Company’s customers accounted for 16% of trade receivables as of September 26, 2009. The Company’s cellular network carriers accounted for 64% and 51% of trade receivables as of September 25, 2010 and as of September 26, 2009, respectively. The additions and write-offs to the Company’s allowance for doubtful accounts during 2010, 2009 and 2008 were not significant.

Vendor Non-Trade Receivables

The Company has non-trade receivables from certain of its manufacturing vendors resulting from the sale of components to these manufacturing vendors who manufacture sub-assemblies or assemble final products for the Company. The Company purchases these components directly from suppliers. Vendor non-trade receivables from two of the Company’s vendors accounted for 57% and 24%, respectively, of non-trade receivables as of September 25, 2010 and two of the Company’s vendors accounted for 40% and 36%, respectively, of non-trade receivables as of September 26, 2009. The Company does not reflect the sale of these components in net sales and does not recognize any profits on these sales until the related products are sold by the Company, at which time any profit is recognized as a reduction of cost of sales.

Note 3 – Fair Value Measurements

The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk.

The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability.

The Company’s valuation techniques used to measure the fair value of money market funds and certain marketable equity securities were derived from quoted prices in active markets for identical assets or liabilities. The valuation techniques used to measure the fair value of all other financial instruments, all of which have counterparties with high credit ratings, were valued based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data.
