NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Symantec Corporation (“we,” “us,” “our,” and “the Company” refer to Symantec Corporation and all of its subsidiaries) as of December 30, 2011 and April 1, 2011, and for the three and nine months ended December 30, 2011 and December 31, 2010, have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, we have omitted certain information and notes normally provided in our annual consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of our financial position and results of operations for the interim periods. These unaudited condensed consolidated financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in our Annual Report on Form 10-K for the fiscal year ended April 1, 2011. The results of operations for the three and nine months ended December 30, 2011 are not necessarily indicative of the results expected for the entire fiscal year. All intercompany accounts and transactions have been eliminated.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current year presentation including the reclassification of certain revenue from Content, subscription and maintenance revenue to License revenue. License revenue includes revenue from software licenses, appliances and certain revenue sharing arrangements.

Significant Accounting Policies

Other than as noted below, there have been no changes in our significant accounting policies for the nine months ended December 30, 2011 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended April 1, 2011.

In the first quarter of fiscal 2012, we adopted updated authoritative accounting guidance related to impairment testing of goodwill. The guidance modified Step 1 of the impairment test for reporting units with zero or negative carrying amounts whereby an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. We performed a Step 2 test on our Services reporting unit due to certain adverse qualitative factors within the reporting unit, which resulted in a goodwill impairment of $19 million. This impairment was recorded to opening Accumulated deficit as of April 2, 2011 as a cumulative-effect adjustment upon adoption. The impact of the cumulative-effect adjustment is as follows:

	Accumulated Deficit			Accumulated Other Comprehensive Income		Other Stockholders’ Equity		Total Symantec Corporation Stockholders’ Equity			Noncontrolling Interest in Subsidiary		Total Stockholders’ Equity
	(In millions)
Beginning balance as of April 2, 2011	$	(4,012	)	$	171	$	8,369	$	4,528		$	77	$	4,605
Cumulative effect adjustment		(19	)		—		—		(19	)		—		(19	)
Beginning balance as adjusted	$	(4,031	)	$	171	$	8,369	$	4,509		$	77	$	4,586

Recently Issued Authoritative Guidance

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-04, “Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” (“ASU 2011-04”). ASU 2011-04 clarifies the application of existing fair value measurement requirements and results in common measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”). ASU 2011-04 also expands the disclosures for fair value measurements that are estimated using significant unobservable (Level 3) inputs. This new guidance is to be applied prospectively for interim and annual reporting periods beginning on or after December 15, 2011. We anticipate that the adoption of this standard will not materially impact our Condensed Consolidated Financial Statements.

6

In June 2011, the FASB issued Accounting Standards Update No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income,” (“ASU 2011-05”). ASU 2011-05 eliminates the option to report other comprehensive income and its components in the statement of changes in equity. ASU 2011-05 requires that all nonowner changes in stockholders’ equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. This new guidance is to be applied retrospectively for interim and annual periods beginning after December 15, 2011. In December 2011, the FASB issued Accounting Standards Update No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”). ASU 2011-12 defers the requirement in ASU 2011-05 to present reclassification adjustments for each component of accumulated other comprehensive income (“AOCI”) in both other comprehensive income and net income on the face of the financial statements and the presentation of reclassification adjustments is not required in interim periods. We expect to continue to present amounts reclassified out of AOCI on the face of the financial statements or disclose those amounts in the notes to the financial statements. The effective dates of ASU 2011-12 are consistent with the effective dates of ASU 2011-05, which is effective for fiscal years and interim periods beginning after December 15, 2011. We do not expect that these standards will materially impact our disclosures included in our Condensed Consolidated Financial Statements.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08, “Intangibles — Goodwill and Other (Topic 350): Testing Goodwill for Impairment,” (“ASU 2011-08”). ASU 2011-08 gives entities the option to perform the two-step process only if they first perform a qualitative assessment to determine whether it is more likely than not (a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount and conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. This new guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted. We anticipate adopting this guidance in our fourth quarter of fiscal 2013 at the time we perform our annual goodwill test and do not expect that this standard will materially impact our Condensed Consolidated Financial Statements.

In December 2011, the FASB issued Accounting Standards Update No. 2011-11, “Disclosures about Offsetting Assets and Liabilities” (“ASU 2011-11”). ASU 2011-11 will require us to disclose information about offsetting and related arrangements to enable users of our financial statements to understand the effect of those arrangements on our financial position. The new guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The disclosures required are to be applied retrospectively for all comparative periods presented. We do not expect that this standard will materially impact our disclosures included in our Condensed Consolidated Financial Statements.

Note 2. Fair Value Measurements

For assets and liabilities measured at fair value such amounts are based on an expected exit price, representing the amount that would be received on the sale of an asset or paid to transfer a liability, as the case may be, in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value:

• Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

• Level 2: Observable inputs that reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3: Unobservable inputs reflecting our own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.

7

Assets Measured and Recorded at Fair Value on a Recurring Basis

There have been no transfers between fair value measurement levels during the three and nine months ended December 30, 2011. The following table summarizes our assets measured at fair value on a recurring basis, by level, within the fair value hierarchy:

	As of December 30, 2011						As of April 1, 2011
	Level 1		Level 2		Total		Level 1		Level 2		Total
	(In millions)
Cash Equivalents (1)	$	1,209	$	—	$	1,209	$	1,866	$	—	$	1,866
Short-term investments (2)		2		51		53		—		8		8
Total	$	1,211	$	51	$	1,262	$	1,866	$	8	$	1,874

⁽¹⁾  Cash equivalents are money market funds which are valued based on quoted market prices of the identical underlying security.

⁽²⁾  Short-term investments primarily consist of corporate debt securities and are classified as available-for-sale securities recognized at amortized cost which is the same as fair value at December 30, 2011. These securities are valued using quoted prices in active markets for identical assets. If quoted prices in active markets for identical assets are not available, we use quoted prices for similar assets that are observable either directly or indirectly.

Assets and Liabilities Measured and Recorded at Fair Value on a Nonrecurring Basis

Goodwill. During the nine months ended December 30, 2011, we did not record any impairment loss on those assets required to be measured at fair value on a nonrecurring basis, other than the cumulative-effect adjustment recorded to the beginning balance of Accumulated deficit. The valuation technique used to estimate the implied fair value of the Services reporting unit goodwill relies on Level 3 inputs, including estimated future cash flows or profit streams. See Note 4 for further information.

Long-Term Debt. As of October 1, 2010, we repurchased $500 million of aggregate principal amount of our 0.75% convertible senior notes, which had a net book value of $481 million. Concurrently with the repurchase, we sold a proportionate share of the initial note hedges back to the note hedge counterparties for approximately $13 million. These transactions resulted in a loss from extinguishment of debt of approximately $16 million, which represents the difference between book value of the notes net of the remaining unamortized discount prior to repurchase and the fair value of the liability component of the notes upon repurchase. The fair value of the liability component was calculated to be $497 million as of October 1, 2010 using Level 2 inputs based on market prices for similar convertible debt instruments and resulting yields.

Note 3. Acquisition

On June 24, 2011, we completed the acquisition of Clearwell Systems Inc. (“Clearwell”), a privately-held provider of eDiscovery solutions. In exchange for all of the voting equity interests of Clearwell, we transferred a total consideration of $392 million, which consists of $364 million in cash, net of $20 million cash acquired, and $8 million of assumed stock options. The objective of the acquisition is to enhance our eDiscovery, archiving and backup offerings to our customers. The results of operations of Clearwell are included since the date of acquisition as part of the Storage and Server Management segment. Supplemental pro forma information for Clearwell was not material to our financial results and therefore has not been included.

The following table presents the purchase price allocation included in our Condensed Consolidated Balance Sheets (in millions):

Net tangible assets (1)	$	33
Intangible assets (2)		154
Goodwill (3)		268
Net tax liabilities		(63	)
Total purchase price	$	392

⁽¹⁾  Net tangible assets included deferred revenue which was adjusted down from $13 million to $3 million, representing our estimate of the fair value of the contractual obligation assumed for support services.

8

⁽²⁾  Intangible assets included customer relationships, developed technology, and tradenames of $82 million, $60 million, and $12 million, respectively, which are amortized over their estimated useful lives of seven to nine years.

⁽³⁾  Goodwill is not tax deductible. The amount resulted primarily from our expectation of synergies from the integration of Clearwell product offerings with our product offerings.

Note 4. Goodwill and Intangible Assets

Goodwill

The changes in the carrying amount of goodwill are as follows:

	Consumer			Security  and Compliance			Storage and  Server Management		Services			Total
	(In millions)
Balance as of April 1, 2011	$	363		$	2,464		$	2,648	$	19		$	5,494
Goodwill impairment (1)		—			—			—		(19	)		(19	)
Goodwill acquired through business combinations (2)		—			—			268		—			268
Goodwill adjustments (3)		(13	)		(5	)		—		—			(18	)
Balance as of December 30, 2011	$	350		$	2,459		$	2,916	$	—		$	5,725

⁽¹⁾  Due to the adoption of new authoritative accounting guidance at the beginning of our fiscal year (see Note 1), we were required to perform a goodwill Step 2 impairment test for our Services reporting unit. As a result, we recognized an impairment loss of $19 million which reduced the carrying value of goodwill allocated to the Services reporting segment to zero. The valuation technique used to estimate the implied fair value of the Services reporting unit goodwill relies on Level 3 inputs, including estimated future cash flows or profit streams. This impairment was recorded to beginning Accumulated deficit as a cumulative-effect adjustment upon adoption.

⁽²⁾  Goodwill acquired through business combinations is related to the acquisition of Clearwell. See Note 3 for further information.

⁽³⁾ Adjustments made to goodwill reflect foreign currency exchange rate fluctuations.

We apply a fair value based impairment test to the carrying value of goodwill and indefinite-lived intangible assets on an annual basis in the fourth quarter of each fiscal year or earlier if indicators of impairment exist. As of December 30, 2011, no indicators of impairment were identified.

Note 6. Investment in Joint Venture

We account for our investment in the joint venture with Huawei Technologies Co., Limited (“Huawei”) under the equity method of accounting. As of December 30, 2011, our proportionate share of the joint venture’s net loss reduced our equity investment to zero. As such, we did not provide for additional losses as we have no commitments to provide financial support to the joint venture. Accordingly, we did not report our share of the joint venture’s net loss for the third quarter of fiscal 2012.

On November 14, 2011, we entered into an agreement to sell our 49% of ownership in the joint venture to Huawei for $530 million. We expect to complete this transaction as soon as practicable, pending regulatory approval.

Note 7. Debt

In fiscal 2007, we issued $1.1 billion in principal amount of 0.75% convertible senior notes (“0.75% Notes”) due June 15, 2011 and $1.0 billion in principal amount of 1.00% convertible senior notes (“1.00% Notes”) due June 15, 2013. In the second quarter of fiscal 2011, we repurchased $500 million of aggregate principal amount of our 0.75% Notes in privately negotiated transactions for approximately $510 million. Concurrently with the repurchase, we sold a proportionate share of the note hedges that we entered into at the time of the issuance of the convertible notes back to the note hedge counterparties for approximately $13 million. The net cost of the repurchase of the 0.75% Notes and the concurrent sale of the note hedges was $497 million in cash. On June 15, 2011, the remaining principal balance on our 0.75% Notes matured and was settled by a cash payment of $600 million. Concurrent with the maturity of the 0.75% Notes, the remaining related note hedges expired. No portion of the 0.75% Notes were converted into our common shares upon maturity.

Note 8. Restructuring and Transition

Our restructuring and transition costs and liabilities consist primarily of severance, facilities costs, and transition and other related costs. Severance generally includes severance payments, outplacement services, health insurance coverage, effects of foreign currency exchange, and legal costs. Facilities costs generally include rent expense and lease termination costs, less expected sublease income. Transition and other related costs consist of severance costs associated with acquisition integrations in efforts to streamline our business operations, consulting charges associated with the implementation of a new Enterprise Resource Planning system, and costs related to the outsourcing of certain back office functions. Restructuring and transition costs are included in the Other segment.

Restructuring Plans

The following restructuring plans are substantially complete:

• Fiscal 2011 Plan. In the first quarter of fiscal 2011, management approved and initiated a plan to expand our consulting partner sales and delivery capabilities. This action was initiated to expand our partner eco-system to better leverage their customer reach and operational scale, which resulted in a headcount reduction within our consulting services organization.

• Fiscal 2010 Plan. In the fourth quarter of fiscal 2010, management approved and initiated a plan to reduce worldwide operating costs through workforce realignment and to reduce operating costs through a facilities consolidation. These actions were initiated to appropriately allocate resources to our key strategic initiatives and streamline our operations to deliver better and more efficient support to our customers and employees. During fiscal 2011, we terminated operating leases and consolidated facilities in North America and Europe. Excess facility obligations are expected to be paid over the respective lease terms, the longest of which extends through fiscal 2018.

11

Other Exit and Disposal Costs

Largely as a result of business acquisitions, management may deem certain leased facilities to be in excess and make a plan to exit them either at the time of acquisition or after the acquisition in conjunction with our efforts to integrate and streamline our operations. As of December 30, 2011, liabilities for these excess facility obligations at several locations around the world are expected to be paid over the respective lease terms, the longest of which extends through fiscal 2016.

Note 9. Commitments and Contingencies

Indemnification

As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is not limited; however, we have directors’ and officers’ insurance coverage that reduces our exposure and may enable us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

We provide limited product warranties and the majority of our software license agreements contain provisions that indemnify licensees of our software from damages and costs resulting from claims alleging that our software infringes the intellectual property rights of a third party. Historically, payments made under these provisions have been immaterial. We monitor the conditions that are subject to indemnification to identify if a loss has occurred.

Litigation Contingencies

For a discussion of our tax litigation with the Internal Revenue Service relating to the 2000 and 2001 tax years of Veritas, see Note 13.

We are also involved in a number of other judicial and administrative proceedings that are incidental to our business. Although adverse decisions (or settlements) may occur in one or more of the cases, it is not possible to estimate the possible loss or losses from each of these cases. The final resolution of these lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on our financial condition or results of operations.

Other

In January 2012, Symantec became aware of claims made by a group of hackers, that it possessed, and intended to publicly expose, portions of the source code for certain Symantec products. Following investigation of these claims, Symantec believes that the group came into possession of the code as a result of a theft of source code that occurred in 2006. Symantec believes that source code for the 2006-era versions of the following products was exposed: Norton Antivirus Corporate Edition; Norton Internet Security; Norton SystemWorks (Norton Utilities and Norton GoBack); and pcAnywhere. Symantec has announced that customers of Symantec’s pcAnywhere product may face an increased security risk as a result of this exposure. The product, pcAnywhere, is also bundled with three Symantec products, Altiris Client Management Suite and Altiris IT Management Suite versions 7.0 or later, and Altiris Deployment Solution with Remote version 7.1. In addition, customers with earlier versions of Altiris suites may have opted to leverage pcAnywhere. The increased risk is isolated to the pcAnywhere components only. Symantec has broadly communicated an outline of the situation to customers, and has provided them with remediation steps to maintain the protection of their devices and information. As of the date of this filing, Symantec has resolved known vulnerabilities and does not believe that this incident will have a material adverse effect on its business, results of operations, financial condition or cash flows.

Note 10. Stock Repurchases

The following table summarizes our stock repurchases:

Range of price paid per share	$	15.38 to $18.83	$	15.38 to $20.51

We have had stock repurchase programs in the past and have repurchased shares on a quarterly basis since the fourth quarter of fiscal 2004 under various programs. Our current program was authorized by our Board of Directors on January 25, 2011 to repurchase up to $1 billion of our common stock. This program does not have an expiration date and as of December 30, 2011, $184 million remained authorized for future repurchases. On January 25, 2012, we announced that our Board of Directors approved a new $1 billion stock repurchase program. This repurchase program does not have a scheduled expiration date.

Note 11. Segment Information

As of December 30, 2011, our five reportable segments are the same as our operating segments and are as follows:

• Consumer. Our Consumer segment focuses on delivering internet security for PC’s, tablets and mobile devices along with services such as online backup, online family protection and remote help to individual users and home offices.

• Security and Compliance. Our Security and Compliance segment focuses on providing large, medium, and small-sized businesses with solutions for endpoint security and management, compliance, messaging management, data loss prevention, encryption, managed security services, and authentication services. These products allow our customers to secure, provision, and remotely manage their laptops, PCs, mobile devices, and servers. We also provide our customers with solutions delivered through our Software-as-a-Service (“SaaS”) security offerings.

• Storage and Server Management. Our Storage and Server Management segment focuses on providing large, medium, and small-sized businesses with storage and server management, backup, archiving, eDiscovery, and data protection solutions across heterogeneous storage and server platforms, as well as solutions delivered through our SaaS offerings.

• Services. Our Services segment provides customers with implementation services and solutions designed to assist them in maximizing the value of their Symantec software. Our offerings include consulting, business critical services, and education.

• Other. Our Other segment is comprised of sunset products and products nearing the end of their life cycle. It also includes general and administrative expenses; amortization of acquired product rights, intangible assets, and other assets; goodwill and intangible asset impairment charges; charges such as stock-based compensation, restructuring and transition expenses; and certain indirect costs that are not charged to the other operating segments.

During the first quarter of fiscal 2012, we modified our segment reporting structure to more readily match our operating structure. The following modification was made to the segment reporting structure: managed security services revenue and expenses moved to the Security and Compliance segment from the Services segment. All historical periods have been adjusted to reflect this modified reporting structure.

Note 12. Stock-based Compensation

The following table summarizes the total stock-based compensation expense recognized in our Condensed Consolidated Statements of Income:

	Three Months Ended						Nine Months Ended

The following table summarizes additional information pertaining to our stock-based compensation:

	Nine Months Ended

Total intrinsic value of stock options exercised		34		32
Total unrecognized compensation expense		37		31
Weighted-average remaining vesting period		3 years		3 years

During the first quarter of fiscal 2012, we granted 91,368 Restricted Stock Awards (“RSAs”) to members of our board of directors. Each RSA had a fair value of $19.70 and vested immediately upon grant. As a result, we recorded approximately $2 million of stock-based compensation expense for these RSAs during the first quarter of fiscal 2012.

Performance Based Awards

During the first quarter of fiscal 2012, we granted performance based restricted stock units (“PRUs”) to certain senior level employees under our 2004 Equity Incentive Plan. The PRU grants are in lieu of the stock option grants typically awarded as part of our annual compensation program. These PRUs can be earned depending upon the achievement of a company-specific performance condition and a market condition as follows: (1) our achievement of a specified company-specific performance target for fiscal 2012 and (2) our two and three year cumulative relative total shareholder return ranked against that of other companies that are included in the Standard & Poor’s 500 Index. These PRUs are also subject to a three year continued service vesting provision with earlier vesting permitted under certain conditions, such as upon a change of control of the company. The determination of the fair value of these awards takes into consideration the likelihood of achievement of the market condition, and the compensation expense for the PRUs is initially based on the probability of achieving the target level of the company-specific performance condition, and will be adjusted for subsequent changes in the estimated or actual outcome of this performance condition. The weighted average grant date fair value of the PRUs was $23.58 per share.

Assumed Clearwell stock options

In connection with our acquisition of Clearwell, we assumed all unexercised, outstanding options to purchase Clearwell common stock. Each unexercised, outstanding option assumed was converted into an option to purchase our common stock after applying the exchange ratio of 0.40906 shares of our common stock for each share of Clearwell common stock which resulted in an allocation of approximately 1 million shares of our common stock to the assumed options. As of December 30, 2011, total unrecognized compensation cost related to the assumed unvested stock options was approximately $9 million, assuming no forfeitures.

Furthermore, all shares obtained upon early exercise of unvested Clearwell options were converted into the right to receive a cash consideration of $7.65 per share upon vesting. The total value of the early exercised, unvested Clearwell shares on the date of acquisition was approximately $4 million, assuming no forfeitures. As of December 30, 2011, total unrecognized compensation cost related to early exercised, unvested Clearwell shares was $2.6 million.

Note 13. Income Taxes

The effective tax rate was approximately 12% and 21% for the three and nine months ended December 30, 2011 respectively, and 20% and 14% for the three and nine months ended December 31, 2010, respectively.

As discussed below, we recognized a $52 million tax benefit arising from the Veritas 2002 through 2005 IRS Appeals matters partially offset by a $4 million tax expense resulting from a change in valuation allowance for certain deferred tax assets in the three and nine months ended December 30, 2011. We further recognized $2 million of tax expense and an additional $14 million tax benefit in the three and nine months ended December 30, 2011, respectively, for discrete events primarily related to tax settlements, lapses of statutes of limitations, and adjustments of prior year items. The tax expense was reduced by a $39 million tax benefit arising from the Veritas v. Commissioner Tax Court decision (see further discussion below) for the nine months ended December 31, 2010, as well as by $11 million and $26 million in tax benefits during the three months and nine months ended December 31, 2010, respectively, for discrete events primarily related to tax settlements and lapses of statutes of limitations, and adjustments of prior year items.

15

The provision for the nine-month periods ended December 30, 2011 and December 31, 2010 otherwise reflects a forecasted tax rate of 29% and 28%, respectively (excluding the tax benefit from our joint venture with Huawei, see Note 6). We include the tax benefit associated with the loss from our joint venture with Huawei in income tax expense rather than netting the tax benefit against our joint venture loss with Huawei. However, the effective rate applied to our joint venture loss with Huawei for purposes of determining the tax benefit is based only on our joint venture loss and its tax impact. The forecasted tax rates for both periods presented reflect the benefits of lower-taxed foreign earnings, domestic manufacturing incentives, and research and development credits (the U.S. federal R&D tax credit expired on December 31, 2011), partially offset by state income taxes. The jurisdictional mix of earnings and the effective tax rate on internationally-derived earnings are relatively consistent in both nine-month periods presented. Substantially all of the foreign earnings were generated by subsidiaries in Ireland and Singapore.

On December 10, 2009, the U.S. Tax Court issued its opinion in Veritas v. Commissioner, finding that our transfer pricing methodology, with appropriate adjustments, was the best method for assessing the value of the transaction at issue between Veritas and its international subsidiary in the 2000 to 2001 tax years. In June 2010, we reached an agreement with the IRS concerning the amount of the adjustment based on the U.S. Tax Court decision. As a result of the agreement, we reduced our liability for unrecognized tax benefits, resulting in a $39 million tax benefit in the first quarter of fiscal 2011. This matter has now been closed and no further adjustments to the accrued liability are expected.

On December 2, 2009, we received a Revenue Agent’s Report from the IRS for the Veritas 2002 through 2005 tax years assessing additional taxes due. We have contested $80 million of the tax assessed and all penalties. As a result of negotiations with IRS Appeals in the three months ended December 30, 2011, we have remeasured our liability for unrecognized tax benefits, resulting in a tax benefit of $52 million.

The timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. Although potential resolution of uncertain tax positions involve multiple tax periods and jurisdictions, it is reasonably possible that a reduction of up to $30 million of the reserves for unrecognized tax benefits may occur within the next 12 months, some of which, depending on the nature of the settlement or expiration of statutes of limitations, may affect our income tax provision and therefore benefit the resulting effective tax rate. The actual amount could vary significantly depending on the ultimate timing and nature of any settlements.

We continue to monitor the progress of ongoing income tax controversies and the impact, if any, of the expected tolling of the statute of limitations in various taxing jurisdictions.

⁽¹⁾ For the periods presented, the effects of the warrants issued and the option purchased in connection with the Convertible Senior Notes were excluded because they have no impact on diluted earnings per share until our average stock price for the applicable period reaches $27.3175 per share and $19.12 per share, respectively.

Note 15. Subsequent Events

On January 13, 2012, we completed the acquisition of LiveOffice, a provider of message hosting and integrated message and social media management applications, including archiving for electronic messaging platforms, cloud-based file storage, and social networking applications. We acquired LiveOffice for a purchase price of approximately $115 million.

On January 25, 2012, we announced that our Board of Directors approved a new $1 billion stock repurchase program. The repurchase program does not have a scheduled expiration date.

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

Forward-Looking Statements and Factors That May Affect Future Results

The discussion below contains forward-looking statements, which are subject to safe harbors under the Securities Act of 1933, as amended, or the Securities Act, and the Exchange Act. Forward-looking statements include references to our ability to utilize our deferred tax assets, as well as statements including words such as “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” and similar expressions. In addition, statements that refer to projections of our future financial performance, anticipated growth and trends in our businesses and in our industries, the anticipated impacts of acquisitions, and other characterizations of future events or circumstances are forward-looking statements. These statements are only predictions, based on our current expectations about future events and may not prove to be accurate. We do not undertake any obligation to update these forward-looking statements to reflect events occurring or circumstances arising after the date of this report. These forward-looking statements involve risks and uncertainties, and our actual results, performance, or achievements could differ materially from those expressed or implied by the forward-looking statements on the basis of several factors, including those that we discuss in Risk Factors, set forth in Part I, Item 1A, of our annual report on Form 10-K for the fiscal year ended April 1, 2011. We encourage you to read that section carefully.

Fiscal Calendar

We have a 52/53-week fiscal accounting year ending on the Friday closest to March 31. The three months ended December 30, 2011 and December 31, 2010 both consisted of 13 weeks. The nine months ended December 30, 2011 and December 31, 2010 both consisted of 39 weeks. Our 2012 fiscal year consists of 52 weeks and ends on March 30, 2012.

OVERVIEW

Our Business

Symantec is a global provider of security, storage, and systems management solutions that help businesses and consumers secure and manage their information. We provide customers worldwide with software and services that protect, manage and control information risks related to security, data protection, storage, compliance, and systems management. We help our customers manage cost, complexity, and compliance by protecting their IT infrastructure as they seek to maximize value from their IT investments.

Our Operating Segments

Our operating segments are significant strategic business units that offer different products and services, distinguished by customer needs. Since the fourth quarter of fiscal 2008, we have operated in five operating segments: Consumer, Security and Compliance, Storage and Server Management, Services, and Other. During the first quarter of fiscal year 2012, we modified our segment reporting structure to more readily match our operating structure. For further descriptions of our operating segments, see Note 11 of the Notes to Condensed Consolidated Financial Statements in this quarterly report. Our reportable segments are the same as our operating segments.

Financial Results and Trends

Revenue increased by $111 million and $532 million for the three and nine months ended December 30, 2011 as compared to the same periods last year. As more fully described below in “Results of Operations”, we experienced growth across all segments except for the Services and the Other segment. We also experienced a favorable foreign exchange effect on our international revenue of approximately $8 million and $158 million for the three and nine months ended December 30, 2011 as compared to the same periods last year.

Our salaries and wages expense increased by $48 million and $230 million for the three and nine months ended December 30, 2011 as compared to the same periods last year. The higher salaries and wages are primarily attributable to an increase in the number of employees to support growth in our business. We also experienced an adverse foreign exchange effect on our expenses of approximately $1 million and $81 million for the three and nine months ended December 30, 2011, respectively, as compared to the same periods last year. Our net income was $240 million and $613 million for the three and nine months ended December 30, 2011, respectively.

Critical Accounting Estimates

There have been no changes in the matters for which we make critical accounting estimates in the preparation of our Condensed Consolidated Financial Statements during the nine months ended December 30, 2011 as compared to those disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended April 1, 2011.

Content, subscription, and maintenance revenue increased for the three months ended December 30, 2011, as compared to the same period last year, as a result of net growth in revenues from our existing products of $92 million and our fiscal 2012 acquisition of $14 million, and a favorable foreign currency exchange effect of $7 million.

Content, subscription, and maintenance revenue increased for the nine months ended December 30, 2011, as compared to the same period last year, as a result of net growth in revenues from our existing products of $148 million and our fiscal 2011 and 2012 acquisitions of $215 million, and a favorable foreign currency exchange effect of $134 million.

License revenue includes revenue from software licenses, appliances and certain revenue sharing arrangements. License revenue increased by $35 million for the nine months ended December 30, 2011, as compared to the same period last year primarily due to a favorable foreign currency exchange effect on our international license revenue of approximately $24 million.

The changes in total net revenue for the three and nine months ended December 30, 2011 are further described in the segment discussions that follow.

Consumer segment revenues increased as a result of continued growth in our internet security products and services. We also experienced a favorable foreign currency exchange effect on our international revenue of approximately $3 million and $49 million for the three and nine months ended December 30, 2011, respectively, as compared to the same periods last year.

Operating income for the Consumer segment increased due to increases in revenue discussed above coupled with lower advertising and promotion expenses, partially offset by increases in salaries and wages of $11 million and $34 million, for the three and nine months ended December 30, 2011, respectively, as compared to the same periods last year. The increase in

consumer revenue was also offset by an adverse foreign currency exchange effect which increased total expenses for the Consumer segment by $1 million and $20 million, respectively, for the three and nine months ended December 30, 2011, as compared to the same periods last year.

Security and Compliance revenue increased for the three months ended December 30, 2011, as compared to the same period last year, as a result of net growth in revenues from our existing products of $73 million and a favorable foreign currency exchange effect of $3 million.

Security and Compliance revenue increased for the nine months ended December 30, 2011, as compared to the same period last year, as a result of net growth in revenues from our existing products of $63 million and $181 million from our fiscal 2011 acquisitions, and a favorable foreign currency exchange effect of $45 million.

For the three months ended December 30, 2011 operating income for the Security and Compliance segment increased due to increases in revenue discussed above and reduced advertising and promotion expenses, as compared to the same period last year. For the nine months ended December 30, 2011, operating income increased due to increases in revenue discussed above, partially offset by increases in salaries and wages of $76 million related to headcount increases as a result of growth in this segment, and increases in cost of sales and equipment costs of $44 million and $18 million, respectively, as compared to the same period last year. For the three and nine months ended December 30, 2011, the increase in revenue was also offset by an adverse foreign currency exchange effect, which increased total expenses for the Security and Compliance segment by $2 million and $22 million, respectively, as compared to the same periods last year.

Storage and server management revenue increased for the three months ended December 30, 2011, as compared to the same period last year, by $14 million as a result of our fiscal 2012 acquisition.

Storage and server management revenue increased for the nine months ended December 30, 2011, as compared to the same period last year, as a result of net growth in revenues of our existing products of $46 million and $34 million from our fiscal 2012 acquisition, and a favorable foreign currency exchange effect of $58 million.

Operating income for the Storage and Server Management segment decreased as a result of an increase in salaries and wages related to sales and marketing personnel of $26 million and $84 million, for the three and nine months ended December 30, 2011. Cost of sales increased due to increased technical support costs and growth of our appliances business of $44 million and $17 million, respectively. In addition, changes in foreign currency exchange rates increased total operating expenses for the Storage and Server Management segment by $6 million for the nine months ended December 30, 2011. These increases in costs were partially offset by the increase in revenue discussed above for the three and nine months ended December 30, 2011, as compared to the same periods last year.

Fluctuations in the U.S. dollar compared to foreign currencies favorably impacted our international revenue by $8 million and $158 million for the three and nine months ended December 30, 2011, respectively, as compared to the same periods last year.

21

Our international revenue is and will continue to be a significant portion of our net revenue. As a result, net revenue will continue to be affected by foreign currency exchange rates as compared to the U.S. dollar. We are unable to predict the extent to which revenue in future periods will be impacted by changes in foreign currency exchange rates. If international sales become a greater portion of our total sales in the future, changes in foreign currency exchange rates may have a potentially greater impact on our revenue and operating results.

Cost of content, subscription, and maintenance consists primarily of fee-based technical support costs, costs of billable services, and payments to OEMs under revenue-sharing agreements. Cost of content, subscription, and maintenance increased for the three and nine months ended December 30, 2011, as compared to the same periods last year, primarily due to higher technical support costs.

Cost of license consists primarily of royalties paid to third parties under technology licensing agreements, appliances, manufacturing and direct material costs. Cost of license increased in the three and nine months ended December 30, 2011, as compared to the same periods last year, as a result of the increased volume of appliance sales.

Acquired product rights are comprised of developed technologies and patents from acquired companies. The decrease in amortization for the nine months ended December 30, 2011, as compared to the same period last year is primarily due to certain acquired product rights from our various past acquisitions becoming fully amortized during the first quarter of fiscal 2011.

Operating Expenses

Our operating expenses increased during the three and nine months ended December 30, 2011, as compared to the same periods last year, due to higher salary and wages and the adverse impact of the change in foreign currency exchange rates, offset by cost savings generated from our restructuring plans discussed below.

As a percentage of revenue, Sales and marketing, Research and development and General and administrative expenses remained consistent during the three and nine months ended December 30, 2011.

During the three months ended December 30, 2011, Sales and marketing expenses increased as compared to the same period last year, primarily as a result of increased salaries and wages of $27 million, partially offset by a decrease in advertising costs of $24 million and a favorable foreign currency exchange effect of $2 million. During the nine months ended December 30, 2011, Sales and marketing expenses increased as compared to the same period last year, primarily as a result of increased salaries and wages of $120 million, and an adverse foreign currency exchange effect of $60 million, partially offset by a decrease in outside services costs of $20 million.

22

Research and development expenses increased during the three and nine months ended December 30, 2011, as compared to the same periods last year, primarily due to increased salaries and wages of $19 million and $85 million, and an adverse foreign currency exchange effect of $3 million and $12 million, respectively.

General and administrative expenses increased during the three and nine months ended December 30, 2011, as compared to the same periods last year due to increased salaries and wages of $3 million and $25 million, respectively.

Other purchased intangible assets are comprised of customer relationships and tradenames. The increase in amortization of other purchased intangible assets for the three months ended December 30, 2011 compared to the same period last year was primarily due to the acquisition of Clearwell. The increase in amortization of other purchased intangible assets for the nine months ended December 30, 2011 compared to the same period last year was primarily due to our fiscal 2011 acquisitions and the acquisition of Clearwell.

Restructuring and transition charges consist of severance, facilities, and transition and other related costs. For the three months ended December 30, 2011, we recognized $5 million of transition and other related costs. For the nine months ended December 30, 2011, we recognized $2 million of severance, $5 million of facilities costs, and $18 million of transition and other related costs. For the three months ended December 31, 2010, we recognized $12 million of severance, $4 million of facilities, and $4 million of transition and other related costs. For the nine months ended December 31, 2010, we recognized $51 million of severance, $24 million in facilities costs, and $13 million of transition and other related costs, respectively. Transition charges are expected to continue in future quarters as we are at the initial stage of implementation of a new Enterprise Resource Planning system. For further information on restructuring and transition, see Note 8 of the Notes to Condensed Consolidated Financial Statements.

During the nine months ended December 31, 2010, we recognized an impairment of $1 million on certain land and buildings classified as held for sale. These impairments were recorded in accordance with the authoritative guidance that requires a long-lived asset classified as held for sale to be measured at the lower of its carrying amount or fair value, less cost to sell.

Non-operating expense decreased for the three and nine months ended December 30, 2011 as a result of lower interest expenses due to our repayment of the $1.1 billion convertible senior note that we issued in fiscal 2007. In the second quarter of fiscal 2011 and the first quarter of fiscal 2012, we made payments of $500 million and $600 million, respectively, to retire these notes.

As discussed below, we recognized a $52 million tax benefit arising from the Veritas 2002 through 2005 IRS Appeals matters partially offset by a $4 million tax expense resulting from a change in valuation allowance for certain deferred tax

23

assets in the three and nine months ended December 30, 2011. We further recognized $2 million of tax expense and an additional $14 million tax benefit in the three and nine months ended December 30, 2011, respectively, for discrete events primarily related to tax settlements, lapses of statutes of limitations, and adjustments of prior year items. The tax expense was reduced by a $39 million tax benefit arising from the Veritas v. Commissioner Tax Court decision (see further discussion below) for the nine months ended December 31, 2010, as well as by $11 million and $26 million in tax benefits during the three months and nine months ended December 31, 2010, respectively, for discrete events primarily related to tax settlements and lapses of statutes of limitations, and adjustments of prior year items.

The provision for the nine-month periods ended December 30, 2011 and December 31, 2010 otherwise reflects a forecasted tax rate of 29% and 28%, respectively (excluding the tax benefit from our joint venture with Huawei; see Note 6 of the Notes to Condensed Consolidated Financial Statements). We include the tax benefit associated with the loss from our joint venture with Huawei in income tax expense rather than netting the tax benefit against our joint venture loss with Huawei. However, the effective rate applied to our joint venture loss with Huawei for purposes of determining the tax benefit is based only on our joint venture loss and its tax impact. The forecasted tax rates for both periods presented reflect the benefits of lower-taxed foreign earnings, domestic manufacturing incentives, and research and development credits (the U.S. federal R&D tax credit expired on December 31, 2011), partially offset by state income taxes. The jurisdictional mix of earnings and the effective tax rate on internationally-derived earnings are relatively consistent in both nine-month periods presented. Substantially all of the foreign earnings were generated by subsidiaries in Ireland and Singapore.

On December 10, 2009, the U.S. Tax Court issued its opinion in Veritas v. Commissioner, finding that our transfer pricing methodology, with appropriate adjustments, was the best method for assessing the value of the transaction at issue between Veritas and its international subsidiary in the 2000 to 2001 tax years. In June 2010, we reached an agreement with the IRS concerning the amount of the adjustment based on the U.S. Tax Court decision. As a result of the agreement, we reduced our liability for unrecognized tax benefits, resulting in a $39 million tax benefit in the first quarter of fiscal 2011. This matter has now been closed and no further adjustments to the accrued liability are expected.

On December 2, 2009, we received a Revenue Agent’s Report from the IRS for the Veritas 2002 through 2005 tax years assessing additional taxes due. We have contested $80 million of the tax assessed and all penalties. As a result of negotiations with IRS Appeals in the December 2011 quarter, we have remeasured our liability for unrecognized tax benefits, resulting in a tax benefit of $52 million.

The timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. Although potential resolution of uncertain tax positions involve multiple tax periods and jurisdictions, it is reasonably possible that a reduction of up to $30 million of the reserves for unrecognized tax benefits may occur within the next 12 months, some of which, depending on the nature of the settlement or expiration of statutes of limitations, may affect our income tax provision and therefore benefit the resulting effective tax rate. The actual amount could vary significantly depending on the ultimate timing and nature of any settlements.

We continue to monitor the progress of ongoing income tax controversies and the impact, if any, of the expected tolling of the statute of limitations in various taxing jurisdictions.

On February 5, 2008, Symantec formed Huawei-Symantec, Inc. (“joint venture”) with a subsidiary of Huawei Technologies Co., Ltd. (“Huawei”). The joint venture is domiciled in Hong Kong with principal operations in Chengdu, China. The joint venture develops, manufactures, markets, and supports security and storage appliances on behalf of global telecommunications carriers and enterprise customers. We record our proportionate share of the joint venture’s net income or loss one quarter in arrears.

24

As discussed in Note 6 of the Notes to Condensed Consolidated Financial Statements, we announced our sale of our interest in the joint venture on November 14, 2012. We expect to complete this transaction as soon as practicable, pending regulatory approval.

For the three and nine months ended December 30, 2011, we recorded a loss of $0 million and $27 million, respectively, related to our share of the joint venture’s net loss incurred for the period from July 1, 2011 to September 30, 2011 and January 1, 2011 to September 30, 2011. For the three and nine months ended December 31, 2010, we recorded a loss of approximately $10 million and $21 million related to our share of the joint venture’s net loss for the period from July 1, 2010 to September 30, 2010 and the period from January 1, 2010 to September 30, 2010, respectively.

Noncontrolling interest in VeriSign Japan

In the second quarter of fiscal 2011, we completed the acquisition of the identity and authentication business of VeriSign, Inc. (“VeriSign”), including a controlling interest in its subsidiary, VeriSign Japan K.K. (“VeriSign Japan”), a publicly traded company on the Tokyo Stock Exchange. Given our majority ownership interest of approximately 54% in VeriSign Japan, the accounts of VeriSign Japan have been consolidated with our accounts, and a noncontrolling interest has been recorded for the noncontrolling investors’ interests in the equity and operations of VeriSign Japan. For the three and nine months ended December 30, 2011, the gain attributable to the noncontrolling interest in VeriSign Japan was approximately $1 million and $0 million, respectively. For the three and nine months ended December 31, 2010, the loss attributable to the noncontrolling interest in VeriSign Japan was approximately $0 million and $2 million, respectively.

LIQUIDITY AND CAPITAL RESOURCES

Sources of Cash

We have historically relied on cash flow from operations, borrowings under a credit facility, and issuances of debt and equity securities for our liquidity needs. As of December 30, 2011, we had cash and cash equivalents of $2.3 billion resulting in a net liquidity position of approximately $3.3 billion, which is defined as cash and cash equivalents and unused availability of the credit facility.

Senior Notes. In the second quarter of fiscal 2011, we issued $350 million in principal amount of 2.75% Notes due December 15, 2015 and $750 million in principal amount of 4.20% Notes due December 15, 2020, for an aggregate principal amount of $1.1 billion.

Revolving Credit Facility. In the second quarter of fiscal 2011, we also entered into a $1 billion senior unsecured revolving credit facility that expires in December 2014. Under the terms of this credit facility, we must comply with certain financial and non-financial covenants, including a covenant to maintain a specified ratio of debt to EBITDA (earnings before interest, taxes, depreciation and amortization). As of December 30, 2011, we were in compliance with all required covenants, and there was no outstanding balance on the credit facility.

We believe that our existing cash and investment balances, our borrowing capacity, our ability to issue new debt instruments, and cash generated from operations will be sufficient to meet our working capital and capital expenditures requirements for at least the next 12 months.

Uses of Cash

Our principal cash requirements include working capital, capital expenditures, payments of principal and interest on our debt, and payments of taxes. Also, we may, from time to time, engage in the open market purchase of our convertible notes prior to their maturity. In addition, we regularly evaluate our ability to repurchase stock, pay debts and acquire other businesses.

Acquisition-Related. For the nine months ended December 30, 2011, we acquired Clearwell for an aggregate payment of $364 million, net of cash acquired. For the nine months ended December 31, 2010, we acquired PGP Corporation, GuardianEdge Technologies, Inc. and the identity and authentication business of VeriSign, Inc, for an aggregate amount of $1.5 billion, net of cash acquired.

25

Convertible Senior Notes. During the nine months ended December 30, 2011, the remaining balance of our 0.75% Notes matured and we settled with the holders with a cash payment of $600 million. See Note 7 of the Notes to Condensed Consolidated Financial Statements for further discussion. During the nine months ended December 31, 2010, we repurchased $500 million of aggregate principal amount of our 0.75% Notes in privately negotiated transactions for approximately $510 million. Concurrently with the repurchase, we sold a proportionate share of the note hedges that we entered into at the time of the issuance of the convertible notes back to the note hedge counterparties for approximately $13 million. The net cost of the repurchase of the 0.75% Notes and the concurrent sale of the note hedges was $497 million in cash.

Stock Repurchases. For the nine months ended December 30, 2011, we repurchased 39 million shares, or $693 million, of our common stock. For the nine months ended December 31, 2010, we repurchased 46 million shares, or $690 million, of our common stock. As of December 30, 2011, we had $184 million remaining under the plan authorized for future repurchases.

U.S. Tax. As of December 30, 2011, $1.7 billion in cash, cash equivalents, and/or marketable securities were held by our foreign subsidiaries. We have provided U.S. deferred taxes on a portion of our undistributed foreign earnings sufficient to address the incremental U.S. tax that would be due if we needed these funds to support our operations in the U.S.

Cash Flows

The following table summarizes selected items in our Condensed Consolidated Statements of Cash Flows:

	Nine Months Ended
	December 30, 2011			December 31, 2010
	(In millions)
Net cash provided by (used in):
Operating activities	$	1,214		$	1,105
Investing activities		(611	)		(1,678	)
Financing activities		(1,216	)		(51	)

Operating Activities

Net cash provided by operating activities was $1.2 billion for the nine months ended December 30, 2011, which resulted from net income of $613 million adjusted for non-cash items, which largely included depreciation and amortization charges of $530 million, stock-based compensation expense of $123 million, and an increase in deferred income taxes of $38 million. These amounts were partially offset by decreases in deferred revenue of $108 million.

Net cash provided by operating activities was $1.1 billion for the nine months ended December 31, 2010, which resulted from net income of $427 million adjusted for non-cash items, which largely included depreciation and amortization charges of $561 million and stock-based compensation expense of $108 million.

Investing Activities

Net cash used in investing activities was $611 million for the nine months ended December 30, 2011, which was due to payments for acquisitions, net of cash acquired, of $364 million, $199 million paid for capital expenditures, and $47 million for available-for-sale securities.

Net cash used in investing activities was $1.7 billion for the nine months ended December 31, 2010, which was due to $1.5 billion of payments for acquisitions, net of cash acquired, and $185 million paid for capital expenditures.

Financing Activities

Net cash used in financing activities was $1.2 billion for the nine months ended December 30, 2011, which was due to the extinguishment of our outstanding 0.75% Notes of $600 million and repurchases of our common stock of $693 million.

Net cash used in financing activities was $51 million for the nine months ended December 31, 2010, which was due to repurchases of common stock of $690 million and repayment of debt of $510 million, partially offset by proceeds from debt issuance, net of discount, of $1.1 billion and net proceeds from sales of common stock through employee stock plans of $66 million.

Contractual Obligations

There have been no significant changes during the nine months ended December 30, 2011 to the contractual obligations disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations, set forth in Part II, Item 7, of our Annual Report on Form 10-K for the fiscal year ended April 1, 2011, other than the extinguishment of our $600 million principal amount of 0.75% convertible senior notes. The table below sets forth these changes but does not update the other line items in the contractual obligations table that appears in the section of our Annual Report on Form 10-K described above:

	Payments Due By Periods
	Total		Remainder of Fiscal 2012		Fiscal 2013 and Fiscal 2014		Fiscal 2015 and Fiscal 2016		Fiscal 2017 and Thereafter

Convertible senior notes (1)	$	1,000	$	—	$	1,000	$	—	$	—

⁽¹⁾ In fiscal 2007, we issued $1.1 billion in principal amount of 0.75% convertible senior notes (“0.75% Notes”) due June 15, 2011 and $1.0 billion in principal amount of 1.00% convertible senior notes (“1.00% Notes”) due June 15, 2013. In the second quarter of fiscal 2011, we repurchased $500 million of aggregate principal amount of our 0.75% Notes in privately negotiated transactions for approximately $510 million. Concurrently with the repurchase, we sold a proportionate share of the note hedges that we entered into at the time of the issuance of the convertible notes back to the note hedge counterparties for approximately $13 million. On June 15, 2011, the remaining principal balance on our 0.75% Notes matured and was settled by a cash payment of $600 million. Concurrent with the maturity of the 0.75% Notes, the remaining related note hedges expired. No portion of the 0.75% Notes were converted into our common shares upon maturity.

27

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no significant changes in our market risk exposures during the nine months ended December 30, 2011 as compared to the market risk exposures disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations, set forth in Part II, Item 7A, of our Annual Report on Form 10-K for the fiscal year ended April 1, 2011.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

The SEC defines the term “disclosure controls and procedures” to mean a company’s controls and other procedures that are designed to ensure that information required to be disclosed in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms. “Disclosure controls and procedures” include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management. Our Chief Executive Officer and our Chief Financial Officer have concluded, based on an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act) by our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, that our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this report.

(b) Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the three months ended December 30, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(c) Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected.

[1] Derived from audited consolidated financial statements.

[2] Due to the adoption of new authoritative accounting guidance at the beginning of our fiscal year (see Note 1), we were required to perform a goodwill Step 2 impairment test for our Services reporting unit. As a result, we recognized an impairment loss of $19 million which reduced the carrying value of goodwill allocated to the Services reporting segment to zero. The valuation technique used to estimate the implied fair value of the Services reporting unit goodwill relies on Level 3 inputs, including estimated future cash flows or profit streams. This impairment was recorded to beginning Accumulated deficit as a cumulative-effect adjustment upon adoption.

[3] Goodwill acquired through business combinations is related to the acquisition of Clearwell. See Note 3 for further information.

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 2. Fair Value Measurements

     For assets and liabilities measured at fair value such amounts are based on an expected exit price, representing the amount that would be received on the sale of an asset or paid to transfer a liability, as the case may be, in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value:

• Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
• Level 2: Observable inputs that reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
• Level 3: Unobservable inputs reflecting our own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.

Assets Measured and Recorded at Fair Value on a Recurring Basis

     There have been no transfers between fair value measurement levels during the three and nine months ended December 30, 2011. The following table summarizes our assets measured at fair value on a recurring basis, by level, within the fair value hierarchy:

		As of December 30, 2011							As of April 1, 2011
		Level 1	Level 2			Total		Level 1		Level 2		Total
						(In millions)
Cash Equivalents (1)	$	1,209	$	—	$	1,209	$	1,866	$	—	$	1,866
Short-term investments (2)		2		51		53		—		8		8
Total	$	1,211	$	51	$	1,262	$	1,866	$	8	$	1,874

(1)

Cash equivalents are money market funds which are valued based on quoted market prices of the identical underlying security.

(2)

Short-term investments primarily consist of corporate debt securities and are classified as available-for-sale securities recognized at amortized cost which is the same as fair value at December 30, 2011. These securities are valued using quoted prices in active markets for identical assets. If quoted prices in active markets for identical assets are not available, we use quoted prices for similar assets that are observable either directly or indirectly.

Assets and Liabilities Measured and Recorded at Fair Value on a Nonrecurring Basis

     Goodwill. During the nine months ended December 30, 2011, we did not record any impairment loss on those assets required to be measured at fair value on a nonrecurring basis, other than the cumulative-effect adjustment recorded to the beginning balance of Accumulated deficit. The valuation technique used to estimate the implied fair value of the Services reporting unit goodwill relies on Level 3 inputs, including estimated future cash flows or profit streams. See Note 4 for further information.

     Long-Term Debt. As of October 1, 2010, we repurchased $500 million of aggregate principal amount of our 0.75% convertible senior notes, which had a net book value of $481 million. Concurrently with the repurchase, we sold a proportionate share of the initial note hedges back to the note hedge counterparties for approximately $13 million. These transactions resulted in a loss from extinguishment of debt of approximately $16 million, which represents the difference between book value of the notes net of the remaining unamortized discount prior to repurchase and the fair value of the liability component of the notes upon repurchase. The fair value of the liability component was calculated to be $497 million as of October 1, 2010 using Level 2 inputs based on market prices for similar convertible debt instruments and resulting yields.

Note 3. Acquisition

     On June 24, 2011, we completed the acquisition of Clearwell Systems Inc. ("Clearwell"), a privately-held provider of eDiscovery solutions. In exchange for all of the voting equity interests of Clearwell, we transferred a total consideration of $392 million, which consists of $364 million in cash, net of $20 million cash acquired, and $8 million of assumed stock options. The objective of the acquisition is to enhance our eDiscovery, archiving and backup offerings to our customers. The results of operations of Clearwell are included since the date of acquisition as part of the Storage and Server Management segment. Supplemental pro forma information for Clearwell was not material to our financial results and therefore has not been included.

Income Taxes [Abstract]

Income Taxes

Note 13. Income Taxes

     The effective tax rate was approximately 12% and 21% for the three and nine months ended December 30, 2011 respectively, and 20% and 14% for the three and nine months ended December 31, 2010, respectively.

     As discussed below, we recognized a $52 million tax benefit arising from the Veritas 2002 through 2005 IRS Appeals matters partially offset by a $4 million tax expense resulting from a change in valuation allowance for certain deferred tax assets in the three and nine months ended December 30, 2011. We further recognized $2 million of tax expense and an additional $14 million tax benefit in the three and nine months ended December 30, 2011, respectively, for discrete events primarily related to tax settlements, lapses of statutes of limitations, and adjustments of prior year items. The tax expense was reduced by a $39 million tax benefit arising from the Veritas v. Commissioner Tax Court decision (see further discussion below) for the nine months ended December 31, 2010, as well as by $11 million and $26 million in tax benefits during the three months and nine months ended December 31, 2010, respectively, for discrete events primarily related to tax settlements and lapses of statutes of limitations, and adjustments of prior year items.

     The provision for the nine-month periods ended December 30, 2011 and December 31, 2010 otherwise reflects a forecasted tax rate of 29% and 28%, respectively (excluding the tax benefit from our joint venture with Huawei, see Note 6). We include the tax benefit associated with the loss from our joint venture with Huawei in income tax expense rather than netting the tax benefit against our joint venture loss with Huawei. However, the effective rate applied to our joint venture loss with Huawei for purposes of determining the tax benefit is based only on our joint venture loss and its tax impact. The forecasted tax rates for both periods presented reflect the benefits of lower-taxed foreign earnings, domestic manufacturing incentives, and research and development credits (the U.S. federal R&D tax credit expired on December 31, 2011), partially offset by state income taxes. The jurisdictional mix of earnings and the effective tax rate on internationally-derived earnings are relatively consistent in both nine-month periods presented. Substantially all of the foreign earnings were generated by subsidiaries in Ireland and Singapore.

     On December 10, 2009, the U.S. Tax Court issued its opinion in Veritas v. Commissioner, finding that our transfer pricing methodology, with appropriate adjustments, was the best method for assessing the value of the transaction at issue between Veritas and its international subsidiary in the 2000 to 2001 tax years. In June 2010, we reached an agreement with the IRS concerning the amount of the adjustment based on the U.S. Tax Court decision. As a result of the agreement, we reduced our liability for unrecognized tax benefits, resulting in a $39 million tax benefit in the first quarter of fiscal 2011. This matter has now been closed and no further adjustments to the accrued liability are expected.

     On December 2, 2009, we received a Revenue Agent's Report from the IRS for the Veritas 2002 through 2005 tax years assessing additional taxes due. We have contested $80 million of the tax assessed and all penalties. As a result of negotiations with IRS Appeals in the three months ended December 30, 2011, we have remeasured our liability for unrecognized tax benefits, resulting in a tax benefit of $52 million.

     The timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. Although potential resolution of uncertain tax positions involve multiple tax periods and jurisdictions, it is reasonably possible that a reduction of up to $30 million of the reserves for unrecognized tax benefits may occur within the next 12 months, some of which, depending on the nature of the settlement or expiration of statutes of limitations, may affect our income tax provision and therefore benefit the resulting effective tax rate. The actual amount could vary significantly depending on the ultimate timing and nature of any settlements.

     We continue to monitor the progress of ongoing income tax controversies and the impact, if any, of the expected tolling of the statute of limitations in various taxing jurisdictions.

Restructuring And Transition [Abstract]

Restructuring And Transition

Note 8. Restructuring and Transition

     Our restructuring and transition costs and liabilities consist primarily of severance, facilities costs, and transition and other related costs. Severance generally includes severance payments, outplacement services, health insurance coverage, effects of foreign currency exchange, and legal costs. Facilities costs generally include rent expense and lease termination costs, less expected sublease income. Transition and other related costs consist of severance costs associated with acquisition integrations in efforts to streamline our business operations, consulting charges associated with the implementation of a new Enterprise Resource Planning system, and costs related to the outsourcing of certain back office functions. Restructuring and transition costs are included in the Other segment.

Restructuring Plans

The following restructuring plans are substantially complete:

· Fiscal 2011 Plan. In the first quarter of fiscal 2011, management approved and initiated a plan to expand our consulting partner sales and delivery capabilities. This action was initiated to expand our partner eco-system to better leverage their customer reach and operational scale, which resulted in a headcount reduction within our consulting services organization.

· Fiscal 2010 Plan. In the fourth quarter of fiscal 2010, management approved and initiated a plan to reduce worldwide operating costs through workforce realignment and to reduce operating costs through a facilities consolidation. These actions were initiated to appropriately allocate resources to our key strategic initiatives and streamline our operations to deliver better and more efficient support to our customers and employees. During fiscal 2011, we terminated operating leases and consolidated facilities in North America and Europe. Excess facility obligations are expected to be paid over the respective lease terms, the longest of which extends through fiscal 2018.

Other Exit and Disposal Costs

     Largely as a result of business acquisitions, management may deem certain leased facilities to be in excess and make a plan to exit them either at the time of acquisition or after the acquisition in conjunction with our efforts to integrate and streamline our operations. As of December 30, 2011, liabilities for these excess facility obligations at several locations around the world are expected to be paid over the respective lease terms, the longest of which extends through fiscal 2016.

Debt

Note 7. Debt

     In fiscal 2007, we issued $1.1 billion in principal amount of 0.75% convertible senior notes ("0.75% Notes") due June 15, 2011 and $1.0 billion in principal amount of 1.00% convertible senior notes ("1.00% Notes") due June 15, 2013. In the second quarter of fiscal 2011, we repurchased $500 million of aggregate principal amount of our 0.75% Notes in privately negotiated transactions for approximately $510 million. Concurrently with the repurchase, we sold a proportionate share of the note hedges that we entered into at the time of the issuance of the convertible notes back to the note hedge counterparties for approximately $13 million. The net cost of the repurchase of the 0.75% Notes and the concurrent sale of the note hedges was $497 million in cash. On June 15, 2011, the remaining principal balance on our 0.75% Notes matured and was settled by a cash payment of $600 million. Concurrent with the maturity of the 0.75% Notes, the remaining related note hedges expired. No portion of the 0.75% Notes were converted into our common shares upon maturity.

⁽¹⁾ Due to the adoption of new authoritative accounting guidance at the beginning of our fiscal year (see Note 1), we were required to perform a goodwill Step 2 impairment test for our Services reporting unit. As a result, we recognized an impairment loss of $19 million which reduced the carrying value of goodwill allocated to the Services reporting segment to zero. The valuation technique used to estimate the implied fair value of the Services reporting unit goodwill relies on Level 3 inputs, including estimated future cash flows or profit streams. This impairment was recorded to beginning Accumulated deficit as a cumulative-effect adjustment upon adoption.

⁽²⁾ Goodwill acquired through business combinations is related to the acquisition of Clearwell. See Note 3 for further information.

⁽³⁾ Adjustments made to goodwill reflect foreign currency exchange rate fluctuations.

Note 11. Segment Information

As of December 30, 2011, our five reportable segments are the same as our operating segments and are as follows:

• Consumer. Our Consumer segment focuses on delivering internet security for PC's, tablets and mobile devices along with services such as online backup, online family protection and remote help to individual users and home offices.

• Security and Compliance. Our Security and Compliance segment focuses on providing large, medium, and small-sized businesses with solutions for endpoint security and management, compliance, messaging management, data loss prevention, encryption, managed security services, and authentication services. These products allow our customers to secure, provision, and remotely manage their laptops, PCs, mobile devices, and servers. We also provide our customers with solutions delivered through our Software-as-a-Service ("SaaS") security offerings.

• Storage and Server Management. Our Storage and Server Management segment focuses on providing large, medium, and small-sized businesses with storage and server management, backup, archiving, eDiscovery, and data protection solutions across heterogeneous storage and server platforms, as well as solutions delivered through our SaaS offerings.

• Services. Our Services segment provides customers with implementation services and solutions designed to assist them in maximizing the value of their Symantec software. Our offerings include consulting, business critical services, and education.

• Other. Our Other segment is comprised of sunset products and products nearing the end of their life cycle. It also includes general and administrative expenses; amortization of acquired product rights, intangible assets, and other assets; goodwill and intangible asset impairment charges; charges such as stock-based compensation, restructuring and transition expenses; and certain indirect costs that are not charged to the other operating segments.

     There were no intersegment sales for the three and nine months ended December 30, 2011 or December 31, 2010. The following table summarizes the results of our operating segments:

     During the first quarter of fiscal 2012, we modified our segment reporting structure to more readily match our operating structure. The following modification was made to the segment reporting structure: managed security services revenue and expenses moved to the Security and Compliance segment from the Services segment. All historical periods have been adjusted to reflect this modified reporting structure.

Commitments And Contingencies [Abstract]

Commitments And Contingencies

Note 9. Commitments and Contingencies

Indemnification

     As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is not limited; however, we have directors' and officers' insurance coverage that reduces our exposure and may enable us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

     We provide limited product warranties and the majority of our software license agreements contain provisions that indemnify licensees of our software from damages and costs resulting from claims alleging that our software infringes the intellectual property rights of a third party. Historically, payments made under these provisions have been immaterial. We monitor the conditions that are subject to indemnification to identify if a loss has occurred.

Litigation Contingencies

     For a discussion of our tax litigation with the Internal Revenue Service relating to the 2000 and 2001 tax years of Veritas, see Note 13.

     We are also involved in a number of other judicial and administrative proceedings that are incidental to our business. Although adverse decisions (or settlements) may occur in one or more of the cases, it is not possible to estimate the possible loss or losses from each of these cases. The final resolution of these lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on our financial condition or results of operations.

Other

     In January 2012, Symantec became aware of claims made by a group of hackers, that it possessed, and intended to publicly expose, portions of the source code for certain Symantec products. Following investigation of these claims, Symantec believes that the group came into possession of the code as a result of a theft of source code that occurred in 2006. Symantec believes that source code for the 2006-era versions of the following products was exposed: Norton Antivirus Corporate Edition; Norton Internet Security; Norton SystemWorks (Norton Utilities and Norton GoBack); and pcAnywhere. Symantec has announced that customers of Symantec's pcAnywhere product may face an increased security risk as a result of this exposure. The product, pcAnywhere, is also bundled with three Symantec products, Altiris Client Management Suite and Altiris IT Management Suite versions 7.0 or later, and Altiris Deployment Solution with Remote version 7.1. In addition, customers with earlier versions of Altiris suites may have opted to leverage pcAnywhere. The increased risk is isolated to the pcAnywhere components only. Symantec has broadly communicated an outline of the situation to customers, and has provided them with remediation steps to maintain the protection of their devices and information. As of the date of this filing, Symantec has resolved known vulnerabilities and does not believe that this incident will have a material adverse effect on its business, results of operations, financial condition or cash flows.

     During the first quarter of fiscal 2012, we granted 91,368 Restricted Stock Awards ("RSAs") to members of our board of directors. Each RSA had a fair value of $19.70 and vested immediately upon grant. As a result, we recorded approximately $2 million of stock-based compensation expense for these RSAs during the first quarter of fiscal 2012.

Performance Based Awards

     During the first quarter of fiscal 2012, we granted performance based restricted stock units ("PRUs") to certain senior level employees under our 2004 Equity Incentive Plan. The PRU grants are in lieu of the stock option grants typically awarded as part of our annual compensation program. These PRUs can be earned depending upon the achievement of a company-specific performance condition and a market condition as follows: (1) our achievement of a specified company-specific performance target for fiscal 2012 and (2) our two and three year cumulative relative total shareholder return ranked against that of other companies that are included in the Standard & Poor's 500 Index. These PRUs are also subject to a three year continued service vesting provision with earlier vesting permitted under certain conditions, such as upon a change of control of the company. The determination of the fair value of these awards takes into consideration the likelihood of achievement of the market condition, and the compensation expense for the PRUs is initially based on the probability of achieving the target level of the company-specific performance condition, and will be adjusted for subsequent changes in the estimated or actual outcome of this performance condition. The weighted average grant date fair value of the PRUs was $23.58 per share.

Assumed Clearwell stock options

     In connection with our acquisition of Clearwell, we assumed all unexercised, outstanding options to purchase Clearwell common stock. Each unexercised, outstanding option assumed was converted into an option to purchase our common stock after applying the exchange ratio of 0.40906 shares of our common stock for each share of Clearwell common stock which resulted in an allocation of approximately 1 million shares of our common stock to the assumed options. As of December 30, 2011, total unrecognized compensation cost related to the assumed unvested stock options was approximately $9 million, assuming no forfeitures.

     Furthermore, all shares obtained upon early exercise of unvested Clearwell options were converted into the right to receive a cash consideration of $7.65 per share upon vesting. The total value of the early exercised, unvested Clearwell shares on the date of acquisition was approximately $4 million, assuming no forfeitures. As of December 30, 2011, total unrecognized compensation cost related to early exercised, unvested Clearwell shares was $2.6 million.

Basis Of Presentation [Abstract]

Basis Of Presentation

Note 1. Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements of Symantec Corporation ("we," "us," "our," and "the Company" refer to Symantec Corporation and all of its subsidiaries) as of December 30, 2011 and April 1, 2011, and for the three and nine months ended December 30, 2011 and December 31, 2010, have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In accordance with those rules and regulations, we have omitted certain information and notes normally provided in our annual consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of our financial position and results of operations for the interim periods. These unaudited condensed consolidated financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in our Annual Report on Form 10-K for the fiscal year ended April 1, 2011. The results of operations for the three and nine months ended December 30, 2011 are not necessarily indicative of the results expected for the entire fiscal year. All intercompany accounts and transactions have been eliminated.

Reclassifications

     Certain prior period amounts have been reclassified to conform to the current year presentation including the reclassification of certain revenue from Content, subscription and maintenance revenue to License revenue. License revenue includes revenue from software licenses, appliances and certain revenue sharing arrangements.

Significant Accounting Policies

     Other than as noted below, there have been no changes in our significant accounting policies for the nine months ended December 30, 2011 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended April 1, 2011.

     In the first quarter of fiscal 2012, we adopted updated authoritative accounting guidance related to impairment testing of goodwill. The guidance modified Step 1 of the impairment test for reporting units with zero or negative carrying amounts whereby an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. We performed a Step 2 test on our Services reporting unit due to certain adverse qualitative factors within the reporting unit, which resulted in a goodwill impairment of $19 million. This impairment was recorded to opening Accumulated deficit as of April 2, 2011 as a cumulative-effect adjustment upon adoption. The impact of the cumulative-effect adjustment is as follows:

					Accumulated			Total Symantec
					Other		Other	Corporation				Noncontrolling		Total

Recently Issued Authoritative Guidance

     In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2011-04, "Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs," ("ASU 2011-04"). ASU 2011-04 clarifies the application of existing fair value measurement requirements and results in common measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards ("IFRS"). ASU 2011-04 also expands the disclosures for fair value measurements that are estimated using significant unobservable (Level 3) inputs. This new guidance is to be applied prospectively for interim and annual reporting

periods beginning on or after December 15, 2011. We anticipate that the adoption of this standard will not materially impact our Condensed Consolidated Financial Statements.

     In June 2011, the FASB issued Accounting Standards Update No. 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income," ("ASU 2011-05"). ASU 2011-05 eliminates the option to report other comprehensive income and its components in the statement of changes in equity. ASU 2011-05 requires that all nonowner changes in stockholders' equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. This new guidance is to be applied retrospectively for interim and annual periods beginning after December 15, 2011. In December 2011, the FASB issued Accounting Standards Update No. 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05" ("ASU 2011-12"). ASU 2011-12 defers the requirement in ASU 2011-05 to present reclassification adjustments for each component of accumulated other comprehensive income ("AOCI") in both other comprehensive income and net income on the face of the financial statements and the presentation of reclassification adjustments is not required in interim periods. We expect to continue to present amounts reclassified out of AOCI on the face of the financial statements or disclose those amounts in the notes to the financial statements. The effective dates of ASU 2011-12 are consistent with the effective dates of ASU 2011-05, which is effective for fiscal years and interim periods beginning after December 15, 2011. We do not expect that these standards will materially impact our disclosures included in our Condensed Consolidated Financial Statements.

     In September 2011, the FASB issued Accounting Standards Update No. 2011-08, "Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment," ("ASU 2011-08"). ASU 2011-08 gives entities the option to perform the two-step process only if they first perform a qualitative assessment to determine whether it is more likely than not (a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount and conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. This new guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted. We anticipate adopting this guidance in our fourth quarter of fiscal 2013 at the time we perform our annual goodwill test and do not expect that this standard will materially impact our Condensed Consolidated Financial Statements.

     In December 2011, the FASB issued Accounting Standards Update No. 2011-11, "Disclosures about Offsetting Assets and Liabilities" ("ASU 2011-11"). ASU 2011-11 will require us to disclose information about offsetting and related arrangements to enable users of our financial statements to understand the effect of those arrangements on our financial position. The new guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The disclosures required are to be applied retrospectively for all comparative periods presented. We do not expect that this standard will materially impact our disclosures included in our Condensed Consolidated Financial Statements.

Investment In Joint Venture [Abstract]

Investment In Joint Venture

Note 6. Investment in Joint Venture

     We account for our investment in the joint venture with Huawei Technologies Co., Limited ("Huawei") under the equity method of accounting. As of December 30, 2011, our proportionate share of the joint venture's net loss reduced our equity investment to zero. As such, we did not provide for additional losses as we have no commitments to provide financial support to the joint venture. Accordingly, we did not report our share of the joint venture's net loss for the third quarter of fiscal 2012.

     On November 14, 2011, we entered into an agreement to sell our 49% of ownership in the joint venture to Huawei for $530 million. We expect to complete this transaction as soon as practicable, pending regulatory approval.
