The unaudited Condensed Consolidated Financial Statements of Juniper Networks, Inc. (the "Company" or "Juniper") have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of December 31, 2012, is derived from the audited Consolidated Financial Statements for the year ended December 31, 2012. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three and ~~six~~nine months ended ~~June~~September 30, 2013, are not necessarily indicative of the results that may be expected for the year ending December 31, 2013, or any future period. The information included in this Quarterly Report on Form 10-Q ("Report") should be read in conjunction with “Management's Discussion and Analysis of Financial Condition and Results of Operations,” “Risk Factors,” “Quantitative and Qualitative Disclosures About Market Risk,” and the Consolidated Financial Statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012. Certain amounts in the prior year Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q have been reclassified to conform to the current year presentation.

The preparation of the financial statements and related disclosures in accordance with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and the accompanying notes. Actual results could differ materially from those estimates under different assumptions or conditions.

In the third quarter of 2013, the Company realigned certain products from its Platform Systems Division ("PSD") segment to its Software Solutions Division ("SSD") segment related to its acquisition of Contrail Systems Inc. ("Contrail"). In addition, in the first quarter of 2013, the Company consolidated operational oversight and management of all security products within the ~~Software Solutions Division ("SSD")~~SSD segment. As a result of this product realignment, security products previously reported in the ~~Platform Systems Division ("PSD")~~PSD segment (including the Branch SRX, Branch Firewall, and J Series product families) are now reported in the SSD segment. The Company reclassified the segment data for the prior ~~period~~periods to conform to the current period's presentation. ~~This change~~These changes did not impact previously reported consolidated net revenues, operating income, net income, and net income per share. See Note 13, Segments, for further discussion of the Company's product realignment.

The Company previously owned a 60 percent interest in a joint venture with Nokia Siemens Networks B.V. (“NSN”). Given the Company's majority ownership interest in the joint venture, the accounts of the joint venture were consolidated with the accounts of the Company, and a noncontrolling interest was recorded for the noncontrolling investor's interests in the net assets and operations of the joint venture. In July 2011, NSN and the Company entered into an agreement to cease operation of and dissolve the joint venture and NSN subsequently ~~NSN~~ assumed the activities of the joint venture. The Company terminated the joint venture in 2013 and the termination did not have a material effect on the Company's financial position or results of operations.

With the exception of the above change in estimate, there have been no material changes to the Company's significant accounting policies as compared to the accounting policies described in Note 2, Significant Accounting Policies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Annual Report on Form 10-K for the year ended December 31, 2012.

The following table summarizes the Company's cash and investments that are classified as restricted cash and investments in the Condensed Consolidated Balance Sheets (in millions):

The Company's Level 2 available-for-sale fixed income securities are priced using quoted market prices for similar instruments or non-binding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, or alternative pricing sources with reasonable levels of price transparency which

are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets. The Company's policy is to recognize asset or liability transfers among Level 1, Level 2, and Level 3 asat the beginning of the ~~actual date of the events or~~quarter in which a change in ~~circumstances that caused~~circumstance resulted in the transfer. During the three and ~~six~~nine months ended ~~June~~September 30, 2013, the Company transferred approximately $287.4 million of government agency bonds within government-sponsored enterprise obligations from Level 1 to Level 2 primarily due to the use of additional valuation inputs more appropriately classified as Level 2 inputs. During the three and nine~~June~~ months ended September 30, 2013, the Company had no transfers to Level 3. During the three and nine months ended September 30, 2012, the Company had no transfers between levels of the fair value hierarchy of its assets or liabilities measured at fair value.

Certain of the Company's assets, including intangible assets, goodwill, and privately-held investments, are measured at fair value on a nonrecurring basis if impairment is indicated. Privately-held investments, which are normally carried at cost, are measured at fair value due to events and circumstances that the Company identified as significantly impacting the fair value of investments. The Company estimated the fair value of its privately-held investments using an analysis of the financial condition and near term prospects of the investee, including recent financing activities and their capital structure. During the three and nine months ended September 30, 2013, privately-held investments with a carrying value of $4.3 million and $4.7 million, respectively, were measured at fair value, resulting in an impairment charge of $2.1 million and $2.5 million, respectively. As of ~~June~~September 30, 2013, these investments were classified as Level 3 assets due to the absence of quoted market prices and inherent lack of liquidity. As of December 31, 2012, the Company had no ~~material~~ assets measured at fair value on a nonrecurring basis.

As of September 30, 2013andDecember 31, 2012, the Company had no liabilities measured at fair value on a nonrecurring basis.

The carrying amounts of the Company's accounts receivable, financing receivables, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. The fair value of the Company’s long-term debt is disclosed in Note 10, Long-Term Debt and Financing, and was determined using quoted market prices (Level 1).

The Company uses derivatives to partially offset its market exposure to fluctuations in certain foreign currencies and does not enter into derivatives for speculative or trading purposes.

The notional amount of the Company's foreign currency derivatives are summarized as follows (in millions):

The Company can use foreign currency forward or option contracts to hedge certain forecasted foreign currency transactions relating to cost of services and operating expenses. The derivatives are intended to hedge the U.S. Dollar equivalent of the Company's planned cost of services and operating expenses denominated in foreign currencies. These derivatives are designated as cash flow hedges. Execution of these cash flow hedge derivatives typically occurs every month with maturities of one year or less. The effective portion of the derivative's gain or loss is initially reported as a component of accumulated other comprehensive income, and upon occurrence of the forecasted transaction, is subsequently reclassified into the cost of services or operating expense line item to which the hedged transaction relates. The Company records any ineffectiveness of the hedging instruments in other ~~(expense) income,~~expense, net, in its Condensed Consolidated Statements of Operations. Cash flows from such hedges are

classified as operating activities. All amounts within other comprehensive income are expected to be reclassified into earnings within the next 12twelve months.

As of ~~June~~September 30, 2013 and December 31, 2012, the total fair value of the Company’s derivative assets recorded in other current assets on the Condensed Consolidated Balance Sheets was $~~1.3~~2.8 million and $3.5 million, respectively. As of ~~June~~September 30, 2013 and December 31, 2012, the total fair value of the Company’s derivative liabilities recorded in other accrued liabilities on the Condensed Consolidated Balance Sheets was $~~2.7~~3.4 million and $0.1 million, respectively.

During the three and ~~six~~nine months ended ~~June~~September 30, 2013, the Company recognized a loss of $~~1.7~~0.4 million and $~~3.8~~4.2 million, respectively, in accumulated other comprehensive ~~(loss)~~ income for the effective portion of its derivative instruments and reclassified a loss of $1.4 million and a gain of $0.6 ~~million~~ ~~and~~ ~~$2.0~~ million, respectively, from other comprehensive income to operating expense in the Condensed Consolidated Statements of Operations. During the three and ~~six~~nine months ended ~~June~~September 30, 2012, the Company

The ineffective portion of the Company's derivative instruments recognized in its Condensed Consolidated Statements of Operations was not material during the three and ~~six~~nine months ended ~~June~~September 30, 2013 and ~~June~~September 30, 2012.

The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. These derivatives do not qualify for special hedge accounting treatment. These derivatives are carried at fair value with changes recorded in other ~~(expense) income,~~expense, net, in the Condensed Consolidated Statements of Operations. Changes in the fair value of these derivatives are largely offset by re-measurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. The derivatives have maturities within two months.

During the three and ~~six~~nine months ended ~~June~~September 30, 2013, the Company recognized a net gain of $~~0.8~~0.9 million and $~~0.1~~1.0 million, respectively, on non-designated derivative instruments within other ~~(expense) income,~~expense, net in its Condensed Consolidated Statements of Operations. During the three and ~~six~~nine months ended ~~June~~September 30, 2012, the Company recognized a net gain of $~~0.4~~0.3 million and $~~0.3~~0.5 million, respectively, within other ~~(expense) income,~~expense, net, in its Condensed Consolidated Statements of Operations.

The Company presents its derivative assets and derivative liabilities on a gross basis in the Condensed Consolidated Balance Sheets. However, under agreements containing provisions on netting with certain counterparties of foreign exchange contracts, subject to applicable requirements, the Company is allowed to ~~net settle~~net-settle transactions on the same date in the same currency, with a single net amount payable by one party to the other. As of ~~June~~September 30, 2013 and December 31, 2012, the potential effect of rights of setoff associated with derivative instruments would be an offset to both assets and liabilities of $~~0.2~~1.1 million and $0.1 million, respectively. The resulting net derivative assets and derivative liabilities of the potential offset impact are $~~1.1~~1.7 million and $~~2.5~~2.3 million as of ~~June~~September 30, 2013, respectively. The resulting net derivative assets are $3.4 million and not material for derivative liabilities as of December 31, 2012. The Company is ~~not~~neither required to pledge nor ~~is it~~ entitled to receive cash collateral related to these derivative transactions.

~~Goodwill~~During the third quarter of 2013, the Company realigned certain products from its PSD segment to its SSD segment resulting in a reclassification of goodwill of $70.6 million related to its acquisition of Contrail. In addition, goodwill of $179.0 million associated with security products previously reported under PSD ~~has been~~was reclassified to SSD in connection with the Company's product realignment of all security products during the first quarter of 2013. See Note 13, Segments, for further discussion of the Company's product ~~realignment.~~realignments. Goodwill was reclassified based on the relative fair value allocation of the reporting units affected. There were no impairments to goodwill during the ~~six~~three and nine months ended~~June~~September 30, 2013 and ~~June~~September 30, 2012.

The purchased intangible assets balance as of ~~June~~September 30, 2013, includes intangible assets acquired through the acquisition completed during the first ~~six months~~quarter of 2013. Refer to Note 3, Business Combinations, for further details.

The Company purchases and holds inventory to provide adequate component supplies over the life of the underlying products. The majority of the Company's inventory is production components. Inventories, net, are reported within prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets and consisted of the following (in millions):

In connection with the 2012 Restructuring Plan discussed in Note 9, Restructuring and Other Charges, the Company recorded a $36.3 million charge during the three and nine months ended September 30, 2012, to cost of revenues for component inventory held in excess of forecasted demand.

Details of the Company's deferred revenue, as reported on the Condensed Consolidated Balance Sheets, were as follows (in millions):

Deferred product revenue represents unrecognized revenue related to shipments to distributors that have not sold through to end-users, undelivered product commitments, and other shipments that have not met all revenue recognition criteria. Deferred product revenue is recorded net of the related costs of product revenue. Deferred service revenue represents ~~customer payments made in advance~~billable amounts for ~~services,~~service contracts, which include technical support, hardware and software maintenance, professional services, and ~~training.~~training, for which services have not been rendered.

Other ~~(Expense) Income,~~Expense, Net

Other ~~(expense) income,~~expense, net, consisted of the following (in millions):

Restructuring charges are based on the Company's restructuring plans that were committed to by management. These restructuring charges are recorded within cost of revenues or restructuring and other charges in the Condensed Consolidated Statements of Operations, as applicable. Any changes in the estimates of executing the approved plans are reflected in the Company's results of operations. Restructuring liabilities are reported within other accrued liabilities and other long-term liabilities on the Condensed Consolidated Balance Sheets.

During the third quarter of 2013, the Company initiated a restructuring plan (the "2013 Restructuring Plan") to continue to improve its cost structure and rationalize its product portfolio and rebalance its investments. The 2013 Restructuring Plan consists of workforce reductions, contract terminations, and project cancellations. The Company recorded $4.5 million in severance costs and $6.6 million of contract termination and project cancellation charges related to the 2013 Restructuring Plan during the three months endedSeptember 30, 2013. The Company expects to incur charges related to this plan through the first half of 2014.

During 2012, the Company initiated a restructuring plan (the "2012 Restructuring Plan") to bring its cost structure more in line with its long-term financial and strategic model. The 2012 Restructuring Plan consists of workforce reductions, facility consolidations orand closures, and supply chain and procurement efficiencies. During the three and ~~six~~nine months ended ~~June~~September 30, 2013, the Company continued to implement restructuring activities under the 2012 Restructuring Plan and recorded $~~8.8~~1.0 million and $~~16.6~~17.6 million, respectively, in charges for ~~workforce reductions,~~severance costs, facility consolidations orand closures, and contract terminations. The Company recorded $29.1 million in severance costs and $0.4 million of other charges related to the 2012 Restructuring Plan during the three and nine months ended September 30, 2012. In connection with these restructuring activities, the Company also recorded certain inventory and intangible asset impairment charges totaling $52.4 million to cost of revenues during the third quarter of 2012. Under the 2012 Restructuring Plan, total costs incurred through ~~June~~September 30, 2013~~, was~~ were $~~109.9~~111.0 million, of which $~~54.4~~56.9 million was recorded within cost of revenues and $~~55.5~~54.1 million was recorded within restructuring and other charges in the Condensed Consolidated Statements of Operations. The ~~Company expects to incur charges~~restructuring activities related to this plan ~~through the end of fiscal 2013.~~are substantially complete.

The following table provides a summary of changes in the restructuring liability related to the Company's plans during the ~~six~~nine months ended ~~June~~September 30, 2013 (in millions):

In connection with the restructuring plans discussed above, the Company expects to record aggregate future charges of approximately $~~1.5 million~~ ~~through the remainder of 2013, consisting of approximately~~ ~~$1.0~~11.0 million related to workforce reductions and ~~$0.5 million~~ ~~related to~~ contract terminations ~~including facility closures.~~through the first half of 2014.

The following table summarizes the Company's long-term debt (in millions, except percentages):

The portion of the receivable financed that has not been recognized as revenue is accounted for as a financing arrangement and is included in other accrued liabilities and other long-term liabilities in the Condensed Consolidated Balance Sheets. As of ~~June~~September 30, 2013 and December 31, 2012, the estimated cash received from the financing provider not recognized as revenue was $~~63.2~~72.5 million and $30.7 million, respectively.

~~As of~~ ~~June 30,~~In July 2013,, the ~~Company had authority granted by the~~Company's Board of Directors (the "Board") approved a stock repurchase program that authorized the Company to repurchase up to $1.0 billion of its common stock ~~under a~~from time to time at management's discretion.

The components of accumulated other comprehensive ~~(loss)~~ income, net of related taxes, during the ~~six~~nine months ended~~June~~September 30, 2013 were as follows (in millions):

The Company’s share-based compensation plans include the 2006 Equity Incentive Plan (the “2006 Plan”), the 2000 Nonstatutory Stock Option Plan (the “2000 Plan”), the Amended and Restated 1996 Stock Plan (the “1996 Plan”), various equity incentive plans assumed through acquisitions, and the 2008 Employee Stock Purchase Plan (the ~~"2008 Purchase Plan"~~"ESPP"). Under these plans, the Company has granted (or in the case of acquired plans assumed) stock options, restricted stock units ("RSUs"), restricted stock awards ("RSAs"), and performance share awards ("PSAs").

The ~~2008 Purchase Plan~~ESPP was adopted in May 2008. To date, the Company's stockholders have approved a share reserve of 19.0 million shares of the Company's common stock for issuance under this plan. The ~~2008 Purchase Plan~~ESPP permits eligible employees to acquire shares of the Company’s common stock at a 15% discount to the offering price (as determined in the ~~2008 Purchase Plan)~~ESPP) through periodic payroll deductions of up to 10% of base compensation, subject to individual purchase limits of 6,000 shares in any twelve-month period or $25,000 worth of stock, determined at the fair market value of the shares at the time the stock purchase option is granted, in one calendar year. As of ~~June~~September 30, 2013, approximately ~~11.4~~12.8 million shares have been issued and ~~7.6~~6.2 million shares remain available for future issuance under the ~~2008 Purchase Plan.~~ESPP.

In connection with certain past acquisitions, the Company assumed stock options, RSU, and RSA awards under the assumed stock plans of the acquired companies and exchanged the assumed awards for Juniper's stock options, RSUs, and RSAs, respectively. No new stock options, RSUs, and RSAs can be granted under these plans. As of ~~June~~September 30, 2013, stock options, RSUs and RSAs representing approximately ~~6.2~~5.5 million shares of common stock were outstanding under all awards assumed through the Company's acquisitions.

The Company’s chief operating decision maker (“CODM”) allocates resources and assesses performance based on financial information of the Company’s divisions. In the third quarter of 2013, the Company realigned certain products from its PSD segment to its SSD segment in connection with its acquisition of Contrail. In addition, in the first quarter of 2013, the Company consolidated operational oversight and management of all security products within the SSD segment. As a result of this change, security products previously reported in the PSD segment (including the Branch SRX, Branch Firewall, and J Series product families) are now reported in the SSD segment. The Company reclassified the segment data for the prior period to conform to the current period's presentation.

The Company’s PSD segment primarily offers scalable routing and switching products that are used in service provider, enterprise, and public sector networks to control and direct network traffic from data centers, core, edge, aggregation, campus, Wide Area Networks ("WANs"), and customer premise equipment level. The Company's PSD segment consists of routing and switching products and services. Routing products and services include the ACX, E, M, MX, PTX, and T Series product families. Switching products and services primarily consist of the EX Series and wireless local area network solutions, as well as QFabric™.

The Company's SSD segment offers solutions that meet a broad array of our customers’ priorities, from protecting the users, applications and data on the network to providing network services across a distributed infrastructure. The SSD segment primarily consists of security, software, management, virtualization, routing products and services. Security includes firewalls (both JUNOS-based SRX and Screen OS-based firewalls), Firefly, virtual private network systems and appliances, secure socket layer virtual private network appliances, intrusion detection and prevention appliances, wide area network optimization platforms, Junos Pulse, and J Series. Software and services for the mobile and wireline network edge include traffic flow monitoring, ~~mobile business services,~~ dynamic application and subscriber awareness, and next generation network ~~addressing, as well as the MobileNext architecture for mobile networks.~~addressing. Management and virtualization products include Junosphere, Junos SDK, JunosV App Engine and the network management platform, Junos Space. In the third quarter of 2013, the Company announced the availability of Juniper Networks Contrail, a standards-based and highly scalable network virtualization and intelligence solution for software-defined networks for enterprises and service providers.

The CODM does not allocate to the Company's business segments certain operating expenses managed separately at the corporate level. Direct costs and operating expenses, such as standard cost of goods sold, research and development, and product marketing expenses, are generally applied to each segment. Indirect costs, such as manufacturing overhead and other cost of revenues, are allocated based on factors including headcount, usage, and revenue. Segment contribution margin provides supplemental data on operational performance and is comprised of these direct costs and operating expenses, as well as these indirect costs. Corporate unallocated expenses include: sales, marketing, general and administrative costs, share-based compensation, amortization of purchased intangible assets, restructuring and other charges, gains or losses on equity investments, other ~~(expense) income,~~expense, net, income taxes, and certain other charges. Segment contribution margin excludes these corporate unallocated expenses.

Depreciation expense allocated to the PSD segment was $~~27.5~~26.8 million and $~~61.9~~88.7 million in the three and ~~six~~nine months ended ~~June~~September 30, 2013, respectively, and $~~28.5~~29.4 million and $~~55.4~~84.8 million in the three and ~~six~~nine months ended ~~June~~September 30, 2012, respectively. Depreciation expense allocated to the SSD segment was $~~6.9~~7.0 million and $~~16.6~~23.6 million in the three and ~~six~~nine months ended ~~June~~September 30, 2013, respectively, and $~~9.2~~9.6 million and $~~18.4~~28.0 million in the three and ~~six~~nine months ended ~~June~~September 30, 2012, respectively.

The Company attributes revenues to geographic region based on the customer’s ship-to location. The following table presents net revenues by geographic region (in millions):

The Company tracks assets by physical location. The majority of the Company’s assets, excluding cash and cash equivalents and investments, as of ~~June~~September 30, 2013 and December 31, 2012, were attributable to United States ("U.S.") operations. As of ~~June~~September 30, 2013 and December 31, 2012, gross property and equipment held in the U.S., as a percentage of total property and equipment, was approximately 84% and 83%, respectively. Although management reviews asset information on a corporate level and allocates depreciation expense by segment, the CODM does not review asset information on a segment basis.

The Company's effective tax rate for the three and ~~six~~nine months ended ~~June~~September 30, 2013 was lower than the federal statutory rate of 35% and the effective tax rate for the same periods in 2012, primarily due to the benefit of the federal research and development ("R&D") credit, the Section 199 deduction for U.S. production activities and earnings in foreign jurisdictions, which are subject to lower tax rates.

The effective tax rate for the three and nine months ended September 30, 2013 includes the effect of the following discrete items (in millions):

During the ~~three and six~~nine months ended ~~June~~September 30, 2013, the Company completed a multi-year study for a Section 199 deduction for U.S. production ~~activities. Section 199~~activities, which provides for a special deduction for taxpayers engaged in qualified production activities within the ~~United States. During the six months ended June 30, 2013,~~U.S. Additionally, the Company finalized a closing agreement with the IRS covering specific matters related to the audit of the Company's federal income tax returns for tax years 2004 through 2006. ~~In addition, on~~On January 2, 2013, the American Taxpayer Relief Act of 2012 retroactively reinstated the U.S. federal R&D tax credit from January 1, 2012 to December 31, 2013.

The rates reflect~~ primarily due to the ~~benefit~~effect of ~~earnings~~changes in foreign ~~jurisdictions, which are subject to lower tax rates, offset by~~earnings coupled with the impact of the ~~Company's investment activity.~~restructuring charges in the period. The effective rates for the periods do not reflect the benefit of the federal R&D credit, which expired on December 31, 2011.

As of ~~June~~September 30, 2013, the total amount of gross unrecognized tax benefits was $~~142.6~~144.0 million, of which $~~126.6~~129.9 million, if recognized, would affect the Company's effective tax rate. The increase in the gross unrecognized tax benefits for the ~~six~~nine months ended ~~June~~September 30, 2013 of approximately $~~6.5~~7.9 million is primarily due to the multi-year claim related to the U.S. production activities deduction partially offset by the IRS tax settlement referenced above.

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. There is a greater than remote likelihood that the balance of the gross unrecognized tax benefits will decrease by approximately $~~3.6~~3.4 million within the next twelve months due to lapses of applicable statutes of limitation and the completion of tax review cycles in various tax jurisdictions.

The Company is pursuing all available administrative remedies relative to these matters. The Company believes that it has adequately provided for any reasonably foreseeable outcomes related to these proposed adjustments and the ultimate resolution of these matters is unlikely to have a material effect on its consolidated financial condition or results of operations; however there is still a possibility that an adverse outcome of these matters could have a material effect on its consolidated financial condition and results of operations. For more information, see Note 16, Commitments and Contingencies, under the heading “IRS Notices of Proposed Adjustments.”

The Company computed basic and diluted net income per share as follows (in millions, except per share amounts):

Basic net income per share is computed using net income available to common stockholders and the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed using net income available to common stockholders and the weighted-average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Dilutive potential common shares consist of common shares issuable upon exercise of stock options, issuances of ESPP, ~~issuances,~~ and vesting of RSUs, RSAs, and PSAs. The Company includes the common shares underlying PSAs in the calculation of diluted net income per share when they become contingently issuable and excludes such shares when they are not contingently issuable.

Potentially dilutive common shares of approximately ~~39.4~~21.8 million and ~~24.3~~22.3 million shares for the three and ~~six~~nine months ended ~~June~~September 30, 2013, respectively, and ~~42.3~~36.8 million and ~~33.2~~33.0 million shares for the three and ~~six~~nine months ended ~~June~~September 30, 2012, respectively, were excluded from the computation of diluted ~~earnings~~net income per share because their effect would ~~have been~~be anti-dilutive.

The Company leases its facilities and certain equipment under non-cancelable operating leases that expire at various dates through November 30, 2022. Certain leases require the Company to pay variable costs such as taxes, maintenance, and insurance and include renewal options and escalation clauses. Future minimum payments under the non-cancelable operating leases totaled $~~239.5~~229.3 million as of ~~June~~September 30, 2013. Rent expense was $~~13.6~~12.6 million and $~~27.3~~39.9 million for the three and ~~six~~nine months ended ~~June~~September 30, 2013, respectively, and $~~15.8~~15.7 million and $~~31.5~~47.2 million for the three and ~~six~~nine months ended ~~June~~September 30, 2012, respectively.

In order to reduce manufacturing lead times and ensure adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. These purchase commitments totaled $~~572.3~~553.3 million as of ~~June~~September 30, 2013. The Company establishes a liability in connection with these purchase commitments related to carrying charges, quantities in excess of our demand forecasts, or obsolete materials charges for materials purchased by contract manufacturers to meet the Company’s forecast or customer orders. As of ~~June~~September 30, 2013, the Company accrued $~~27.6~~24.2 million based on its estimate of such charges.

As of ~~June~~September 30, 2013, the Company had $~~115.7~~117.5 million included in long-term income taxes payable in the Condensed Consolidated Balance Sheets for unrecognized tax positions. At this time, the Company is unable to make a reasonably reliable estimate of the timing of payments related to this amount due to uncertainties in the timing of tax audit outcomes.

The Company enters into agreements with customers that contain indemnification provisions relating to potential situations where claims could be alleged that the Company’s products infringe the intellectual property rights of a third-party. The Company also has financial guarantees consisting of guarantees of product and service performance, guarantees related to third-party customer-financing arrangements, custom and duty guarantees, and standby letters of credit for certain lease facilities. As of ~~June~~September 30, 2013 and December 31, 2012, the Company had $~~43.3~~42.4 million and $12.6 million, respectively, in financing guarantees, bank guarantees, and standby letters of credit related to these financial guarantees, of which $32.2 million in financing guarantees iswas recorded in other accrued liabilities and other long-term liabilities in the Condensed Consolidated Balance Sheets as of ~~June~~September 30, 2013. See Note 10, Long-Term Debt and Financing, for further discussion of the Company's third-party ~~customer-financing~~customer financing arrangements that contain guarantee provisions.

The Company is involved in disputes, litigation, and other legal actions, including, but not limited to, the matters described below. The Company is aggressively defending its current litigation matters, and while there can be no assurances and the outcome of these matters is currently not determinable, the Company currently believes that there are no existing claims or proceedings that are likely to have a material adverse effect on its financial position. There are many uncertainties associated with any litigation and these actions or other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of those events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses. Unless otherwise noted below, during the period presented, we have

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

The following discussion is based upon our unaudited Condensed Consolidated Financial Statements included in Part 1, Item I, of this Report, which have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In the course of operating our business, we routinely make decisions as to the timing of the payment of invoices, the collection of receivables, the manufacturing and shipment of products, the fulfillment of orders, the purchase of supplies, and the building of inventory and spare parts, among other matters. Each of these decisions has some impact on the financial results for any given period. In making these decisions, we consider various factors, including contractual obligations, customer satisfaction, competition, internal and external financial targets and expectations, and financial planning objectives.

To aid in understanding our operating results for the periods covered by this Report, we have provided an executive overview and summary of our business and market environment along with a financial results overview. These sections should be read in conjunction with the more detailed discussion and analysis of our consolidated financial condition and results of operations in this Item 2, our “Risk Factors” section included in Item 1A of Part II, and our unaudited Condensed Consolidated Financial Statements and Notes included in Item 1 of Part I of this Report, as well as our audited Consolidated Financial Statements and Notes included in Item 8 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

At Juniper Networks, we focus on all aspects of the network—across routing, switching, and security. We design, develop, and sell products and services that enable high-performance networks, which combine scale and performance with agility and efficiency, so customers can build the best networks for their businesses. We serve the high-performance networking requirements of global service providers, enterprises, governments, and research and public sector organizations that view the network as critical to their success. Our silicon, systems, and software represent innovations that transform the economics and experience of networking, helping customers achieve superior performance, greater choice, and flexibility, while reducing overall total cost of ownership.

In the ~~second~~third quarter of 2013, we continued to see ~~momentum with certain of our existing routing and switching offerings, including new~~ customer adoption ~~of our QFabric solutions,~~with several product offerings across routing, switching, and security, including the MX Series, EX Series, T4000 Core Routers and ~~EX Series switches. We released a series~~QFabric System. During the third quarter of new products for the enterprise campus and data center infrastructures, including the EX9200 Ethernet Switch, a programmable core switch, to support emerging applications and growing workloads. Additionally, we released the MX2020, a service provider edge router designed for rapid service delivery and application enablement. We also introduced a family of products for software defined networks ("SDN"), including the JunosV Contrail Controller beta, an open standards-based controller that we expect will reduce the time, cost and risk for service provider and enterprise customers to deliver new network and security services. Furthermore,2013, we announced the availability of ~~Junos DDoS Secure~~Juniper Networks Contrail, a standards-based and highly scalable network virtualization and intelligence solution for software-defined networks ("SDN") and introduced OpenContrail, a new initiative that makes the source code library for Contrail available through an open source license, which we believe will help to ~~protect data centers against increasingly complex distributed denial of service attacks, as well as network automation and orchestration tools for simplifying data center operations.~~foster innovation in SDN.

We remain focused on improved operational execution, continued innovation, and prudent capital allocation. We continue to believe that the underlying trends driving network investment around the cloud and mobility are intact and remain strong. We have focused on driving leverage in our financial model and continue to bring our cost structure in line with our long-term operating model. ~~We revised~~During the third quarter of 2013, we initiated a restructuring plan (the "2013 Restructuring Plan") to continue to improve our cost structure and rationalize our product portfolio and rebalance our investments. The 2013 Restructuring Plan consists of workforce reductions, contract terminations, and project cancellations of which $11.1 million was recorded in the third quarter of 2013. We expect to record aggregate future charges of approximately $11.0 million related to workforce reductions and contract terminations through the first half of 2014 related to our restructuring plans. We continue to anticipate that our restructuring and cost reduction ~~goal from $150.0 million to~~activities will result in estimated annual cost savings of $100.0 million, with $50.0 million attributed to ~~the~~ savings in operating expenses and the remaining $50.0 million in savings to cost of revenues, which is in line with our year-over-year goal. The revision is due to an increase in legal fees and due to an improved demand environment, variable expenses are higher than anticipated for 2013. We are also making incremental investments during the second half of 2013 to support our revenue growth opportunities.revenues.

The following table provides an overview of our key financial metrics (in millions, except per share amounts, percentages, days sales outstanding ("DSO"), and book-to-bill):

Net Revenues: During the three and ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same periods in 2012, we experienced net revenue growth in the Americas, ~~partially offset by a decline in APAC, as well as an increase in net revenues~~especially in the service provider market, partially offset by declines in APAC and ~~improved demand in the enterprise market.~~EMEA. The year-over-year increase in our net revenues during the three and ~~six~~nine months ended ~~June~~September 30, 2013, was primarily due to an increase ~~from the~~in sales offrom our edge routing and switching products, partially offset by a decline in sales from our ~~high-end~~ security products.

Gross Margin: Our gross margin as a percentage of net revenues increased for the three and ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same periods in 2012, primarily due to ~~a substantial improvement in service gross margin, as well as cost reductions~~higher restructuring and other charges recorded in the ~~supply chain.~~three and nine months ended September 30, 2012.

Operating Income: Our operating income increased as a percentage of net revenues during the three and ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same periods in 2012, primarily due to the growth in net revenues and gross ~~margin, as we continue~~margin. Also contributing to ~~invest~~the increase in ~~our innovative portfolio, bring new products to market,~~operating income were higher restructuring and ~~optimize our cost structure.~~other charges recorded in the three and nine months ended September 30, 2012, of $83.4 million and $88.6 million, respectively. For the ~~six~~nine months ended ~~June~~September 30, 2013, the increase in operating income was partially offset by ~~litigation~~ charges of $10.3 million for commercial litigation which were recorded during the first quarter of 2013.

Operating Cash Flows: Operating cash flows decreased during the ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same period in 2012, primarily due to timing of ~~payments to vendors, higher taxes paid, a decrease in accrued compensation, and~~receipts from our customers, an increase in ~~accounts receivable, partially offset by an increase in net income~~annual payments for incentive compensation for our employees, and ~~deferred revenue.~~higher taxes paid.

DSO: DSO is calculated as the ratio of ending accounts receivable, net of allowances, divided by average daily net sales for the preceding 90 days. DSO for the ~~second~~third quarter of 2013 increased by 610 days, or ~~18%~~31% compared to the same period in 2012. The increase in DSO was primarily due to stronger cash collections and better shipment linearity in the ~~second~~third quarter of 2012, as compared to the current period.

Book-to-bill: Book-to-bill represents the ratio of product orders booked divided by product revenues during the respective period. Book-to-bill was greater than one for the three months ended ~~June~~September 30, 2013 and ~~June~~September 30, 2012.

Stock Repurchase Plan Activity: Under our stock repurchase ~~program,~~programs, we repurchased approximately ~~6.4~~4.4 million shares of our common stock in the open market at an average price of $~~16.45~~20.92 per share for an aggregate purchase price of $~~105.5~~92.9 million during the three months ended ~~June~~September 30, 2013, and ~~12.6~~17.0 million shares of our common stock at an average price of $~~18.68~~19.32 per share for an aggregate purchase price of $~~235.4~~328.4 million during the ~~six~~nine months ended ~~June~~September 30, 2013.

Deferred Revenue: Total deferred revenue increased by $~~104.6~~97.8 million to $~~1,028.0~~1,021.2 million as of ~~June~~September 30, 2013, compared to $923.4 million as of December 31, 2012, primarily due to an increase in deferred service revenue ~~resulting from an increase in~~driven by the execution of several multi-year support agreements and annual agreement renewals, slightly offset by a decrease in deferred product revenue.

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires us to make judgments, assumptions, and estimates that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. On an ongoing basis, we evaluate our estimates and assumptions. These estimates and assumptions are based on current facts, historical experience, and various other factors that we believe are reasonable under the circumstances to determine reported amounts of assets, liabilities, revenue and expenses that are not readily apparent from other sources.

An accounting policy is considered to be critical if the nature of the estimates or assumptions is material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and the effect of the estimates and assumptions on financial condition or operating performance is material. The accounting policies we believe to reflect our more significant estimates, judgments, and assumptions and are most critical to understanding and evaluating our reported financial results are as follows:

During the ~~six~~nine months ended ~~June~~September 30, 2013, there were no significant changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates disclosed in Management's Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2012.

The following table presents product and service net revenues (in millions, except percentages):

The following table presents net revenues by market (in millions, except percentages):

~~Service~~Product gross margin percentage increased during the three and ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same periods in 2012, primarily due to a ~~2012~~$36.3 million inventory charge related to component inventory held in excess of forecasted demand and intangible asset impairment charges of $16.1 million recorded during the three and nine months ended September 30, 2012.

Service gross margin percentage was relatively flat during the three months ended September 30, 2013, compared to the same period in 2012. During the nine months ended September 30, 2013, compared to the same period in 2012, service gross margin increased primarily due to cost reductions and greater efficiency in the delivery of services.

Our operating expenses have historically been driven by personnel-related costs, including wages, commissions, bonuses, vacation, benefits, share-based compensation, and travel, and we expect this trend to continue. Facility and information technology (“IT”) departmental costs are allocated to other departments based on usage and headcount.

Sales and marketing expense increased during the three and ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same periods in 2012, primarily due to higher commissions during the second and third quarter of 2013 ~~partially offset by a decrease in outside service expense.~~resulting from improved sales achievement.

~~Restructuring charges increased~~In connection with our restructuring plans, we recorded $6.0 million and $21.0 million during the three and ~~six~~nine months ended ~~June~~September 30, 2013, respectively, in charges for workforce reductions, facility-related charges, and contract terminations. Restructuring and other charges decreased during the three and nine months ended September 30, 2013, compared to the same periods in 2012, due to ~~our 2012 Restructuring Plan. During~~higher restructuring and other charges recorded in the ~~three and six~~ ~~months ended~~ ~~June 30, 2013, we recorded~~ ~~$8.0 million~~ ~~and~~ ~~$15.0 million, respectively, in charges for workforce reductions, facility consolidations or closures, and contract terminations related to our restructuring plans. In connection with our restructuring plans, we~~comparable periods of 2012. We expect to record aggregate future charges of approximately $~~1.5 million~~ ~~through the remainder of 2013, consisting of approximately~~ ~~$1.0~~11.0 million related to workforce reductions and ~~$0.5 million~~contract terminations through the first half of 2014 related to ~~contract terminations including facility closures.~~our restructuring plans.

Share-based compensation expense associated with stock options, employee stock purchases, restricted stock units ("RSUs"), restricted stock awards ("RSAs") and performance share awards ("PSAs") was recorded in the following cost and expense categories (in millions, except percentages):

Share-based compensation expense ~~decreased~~increased during the three ~~and six~~ months ended ~~June~~September 30, 2013, compared to the same period in 2012, primarily due to expense related to RSAs assumed in connection with our acquisition of Contrail at the end of 2012 and an increase in grant date fair values due to higher stock prices during the period. During the nine months ended September 30, 2013, compared to the same period in 2012, share-based compensation expense decreased primarily due to a decrease in actual shares vested and a decline in grant date fair values due to lower stock prices during the period, partially offset by expense related to RSAs assumed in connection with our acquisition of Contrail ~~Systems Inc.~~ at the end of 2012.

For the three and ~~six~~nine months ended ~~June~~September 30, 2013 and ~~June~~September 30, 2012, foreign currency fluctuations were not ~~material.~~material to our financial results.

During the three and ~~six~~nine months ended ~~June~~September 30, 2013, PSD product revenues increased, compared to the same periods in 2012, primarily due to ~~good~~increased revenue from the enterprise and service provider ~~performance~~markets and growth in sales of our routing and switching products, specifically the MX, PTX, EX, and ~~QFabric.~~QFabric product families.

During the three and ~~six~~nine months ended ~~June~~September 30, 2013, PSD service revenues increased, compared to the same periods in 2012, primarily due to strong contract renewals of support services.

PSD contribution margin as a ~~percent~~percentage of PSD revenues increased during the three and ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same periods in 2012, due to a combination of revenue growth and lower operating expenses.

During the three and ~~six~~nine months ended ~~June~~September 30, 2013, SSD product revenues decreased, compared to the same periods in 2012, primarily due to a decline in sales of our high-end firewall ~~products, offset by a slight increase in certain routing~~ products. ~~We are focused on stabilizing the security business in the second half of 2013 with a return to growth in future periods.~~

During the three and ~~six~~nine months ended ~~June~~September 30, 2013, SSD service revenues increased, compared to the same periods in 2012, due to strong contract renewals of support services.

Historically, we have funded our business primarily through our operating activities, ~~and~~ the issuance of our common stock, and ~~more recently,~~ the issuance of our long-term debt. The following table presents our capital resources (in millions, except percentages):

The significant components of our working capital are cash and cash equivalents, short-term investments, and accounts receivable, reduced by accounts payable, accrued liabilities, and short-term deferred revenue. Working capital increased by $~~52.6~~101.1 million during the ~~six~~nine months ended ~~June~~September 30, 2013, due to an increase in current assets, primarily short-term investments and accounts receivable, partially offset by a decrease in cash and cash equivalents.

During the ~~six~~nine months ended ~~June~~September 30, 2013, cash and cash equivalents decreased by $~~157.9~~136.3 million primarily due to repurchases of common stock, capital expenditures, and payments related to incentive compensation.

Net cash provided by operations for the ~~six~~nine months ended ~~June~~September 30, 2013, was $~~275.5~~451.9 million, compared to net cash provided by operations of $~~314.4~~487.6 million for the same period in 2012. Net cash provided by operations decreased during the ~~six~~nine months ended ~~June~~September 30, 2013, compared to the same period in 2012, primarily due to an increase in accounts receivable due to the timing of ~~payments to our vendors, higher taxes paid,~~collections, a decrease in accrued compensation due to annual payments for incentive compensation for our employees, and ~~an increase in accounts receivable due to the timing of collections, partially offset by an increase in net income and deferred revenue.~~higher taxes paid.

For the ~~six~~nine months ended ~~June~~September 30, 2013, net cash used in investing activities was $~~300.8~~421.7 million, compared to $~~93.7~~367.8 million for the ~~six~~nine months ended ~~June~~September 30, 2012. The increase in net cash used in investing activities was primarily due to purchases of investments, partially offset by proceeds from the sale of investments.

Net cash used in financing activities was $~~132.6~~166.5 million for the ~~six~~nine months ended ~~June~~September 30, 2013, compared to $~~86.8~~322.3 million for the same period in 2012. The ~~increase~~decrease in net cash used in financing activities was primarily due to higher purchases and retirement of our common stock during the comparable period in 2012, partially offset by ~~an increase in proceeds from employee stock option exercises as well as~~ proceeds from customer financing arrangements in the second quarter of 2013.

In ~~June 2012,~~July 2013, our Board of Directors (the "Board") ~~granted authority to the Company~~approved a stock repurchase program that authorized us to repurchase up to $1.0 billion of our common stock ~~under our~~from time to time at management's discretion. The authorization was in addition to the $1.0 billion stock repurchase ~~program.~~program approved by our Board and announced in June 2012. As of ~~June~~September 30, 2013, there iswas $~~332.8 million~~1.2 billion of authorized funds remaining under our stock repurchase ~~program.~~programs.

During the three and ~~six~~nine months ended ~~June~~September 30, 2013, we repurchased and retired approximately ~~6.4~~4.4 million and ~~12.6~~17.0 million shares of our common stock under our stock repurchase ~~program~~programs at an average price of $~~16.45~~20.92 and $~~18.68~~19.32 per share for an aggregate purchase price of $~~105.5~~92.9 million and $~~235.4~~328.4 million, respectively. During the three and nine months ended September 30, 2012, we repurchased and retired approximately 13.9 million and 21.3 million shares of our common stock under our stock repurchase programs at an average price of $18.00 and $18.60 per share for an aggregate purchase price of $250.0 million and $395.6 million, respectively.

As of ~~June~~September 30, 2013, our restructuring liability was $~~12.0~~17.3 million of which $~~4.1~~11.1 million related to severance and contract ~~termination~~terminations and other charges, which are expected to be ~~substantially~~ paid ~~during~~through the ~~third quarter~~first half of ~~fiscal 2013.~~2014. The remaining $~~7.9~~6.2 million related to facility closures are expected to be paid through March 2018.

The following table summarizes our deferred product and service revenues (in millions):

As of ~~June~~September 30, 2013, net deferred product revenue decreased by $~~18.4~~16.1 million compared to December 31, 2012, due to releases of product revenue primarily relating to a large U.S. federal government contract in ~~U.S. federal.~~the second quarter of 2013. As of ~~June~~September 30, 2013, the increase in deferred service revenue of $~~123.0~~113.9 million compared to December 31, 2012, was driven by ~~normal seasonality in addition to~~ the execution of ~~a few~~several multi-year support agreements and annual agreement renewals.

As of ~~June~~September 30, 2013, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. It is not our business practice to enter into off-balance sheet arrangements. However, in the normal course of business, we enter into contracts consisting of guarantees of product and service performance, guarantees related to third-party customer-financing arrangements, customs and duties guarantees, and standby letters of credit for certain lease facilities. See Note 16, Commitments and Contingencies, in Notes to the Condensed Consolidated Financial Statements in Item 1 of Part I of this Report for additional information regarding our guarantees.

Liquidity and Capital Resource Requirements

Liquidity and capital resources may be impacted by our operating activities as well as acquisitions and investments in strategic relationships that we have made or we may make in the future. Additionally, if we were to repurchase additional shares of our common stock under our stock repurchase ~~program,~~programs, our liquidity may be impacted. As of ~~June~~September 30, 2013, ~~60%~~59% of our cash, cash equivalents, and investment balances were held outside of the U.S., which may be subject to U.S. taxes if repatriated.

In August ~~2010,~~2013, we filed ~~a $1.5 billion~~an automatic shelf registration statement with the ~~SEC. In March 2011, we issued notes~~SEC to replace our previous shelf registration statement, which expired pursuant to SEC rules in ~~the~~September 2013. The August 2013 automatic shelf registration statementenables us to offer for sale, from time to time, an unspecified amount of ~~$1.0 billion under the shelf registration statement. Therefore, while we have no current plans to do so, we may issue up to $500 million~~securities in ~~additional securities under the shelf registration statement. The shelf registration~~one or more offerings and is intended to give us flexibility to take advantage of financing opportunities as needed or deemed desirable in light of market conditions. Any ~~additional~~ offerings of securities under the automatic shelf registration statement will be made pursuant to a prospectus.

A description of the risk factors associated with our business is included under “Risk Factors” in Item 1A of Part II of this Report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Item 4. Controls and Procedures

Attached, as exhibits to this report are certifications of our principal executive officer and principal financial officer, which are required in accordance with Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This “Controls and Procedures” section includes information concerning the controls and related evaluations referred to in the certifications and it should be read in conjunction with the certifications for a more complete understanding of the topics presented.

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

There were no changes in our internal control over financial reporting that occurred during the ~~second~~third quarter of 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Our controls and procedures are designed to provide reasonable assurance that our control system’s objectives will be met and our CEO and CFO have concluded that our disclosure controls and procedures are effective at the reasonable assurance level. 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. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of these controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Item 1. Legal Proceedings

The information set forth under the “Legal Proceedings” section in Note 16, Commitments and Contingencies, in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report, is incorporated herein by reference.

Item 1A. Risk Factors

Investments in our securities involve significant risks. The market price of our stock has historically reflected a higher multiple of earnings than many other companies. Accordingly, even small changes in investor expectations for our future growth and earnings, whether as a result of actual or rumored financial or operating results, changes in the mix of the products and services sold, acquisitions, industry changes, or other factors, could trigger, and have triggered in the past, significant fluctuations in the market price of our common stock. Investors in our securities should carefully consider all of the relevant factors disclosed by us, including, but not limited to, the following factors, that could affect our business, operating results and stock price.

Our revenues and operating results may vary significantly from quarter-to-quarter due to a number of factors, many of which are outside of our control and any of which may cause our stock price to fluctuate.

The factors that may cause our quarterly results to vary quarter by quarter and be unpredictable include, but are not limited to: limited visibility into customer spending plans, changes in the mix of products and services sold, changes in geographies in which our products and services are sold, changing market and economic conditions, current and potential customer consolidation, competition, customer concentration, long sales and implementation cycles, regional economic and political conditions, and seasonality. For example, we, and many companies in our industry, experience adverse seasonal fluctuations in customer spending, particularly in the first and third quarters. Market trends, competitive pressures, commoditization of products, seasonal rebates, increased component or shipping costs, regulatory impacts and other factors may result in reductions in revenue or pressure on gross margins of certain segments in a given period, which may necessitate adjustments to our operations.

~~Table of Contents~~

As a result of these factors, as well as other variables affecting our operating results, we believe that quarter-to-quarter comparisons of operating results are not necessarily a good indication of what our future performance will be. It is likely that in some future quarters, our operating results may be below our guidance, our long-term financial model or the expectations of securities analysts or investors, in which case the price of our common stock may decline. Such a decline could occur, and has occurred in the past, even when we have met our publicly stated revenues and/or earnings guidance.

Fluctuating economic conditions make it difficult to predict revenues for a particular period and a shortfall in revenues or increase in costs of production may harm our operating results.

Our revenues and gross margin depend significantly on general economic conditions and the demand for products in the markets in which we compete. Economic weakness, customer financial difficulties, and constrained spending on network expansion and enterprise infrastructure have in the past resulted in, and may in the future result in, decreased revenues and earnings. Such factors could make it difficult to accurately forecast sales and operating results and could negatively affect our ability to provide accurate forecasts to our contract manufacturers and manage our contract manufacturer relationships and other expenses. In addition, economic uncertainty concerns over the sovereign debt situation in certain countries in the European Union, as well as continued turmoil in the geopolitical environment in many parts of the world, have, and may continue to, put pressure on global economic conditions, which has led, and could continue to lead, to reduced demand for our products, to delays or reductions in network expansions or infrastructure projects, and/or higher costs of production. Economic weakness may also lead to longer collection cycles for payments due from our customers, an increase in customer bad debt, restructuring initiatives and associated expenses, and impairment of investments. Furthermore, ~~continued weakness~~uncertainty regarding the U.S. federal budget and the ~~sovereign debt situation in certain countries~~recent sequestration, as well as instability in the ~~European Union,~~global credit markets, may adversely impact the ability of our customers to adequately fund their expected capital expenditures, which could lead to delays or cancellations of planned purchases of our products or services. In addition, our operating expenses are largely based on anticipated revenue trends and a high percentage of our expenses is, and will continue to be, fixed in the short and medium term.

Table of Contents

Uncertainty about future economic conditions, including the impact of uncertainty regarding the U.S. federal budget, also makes it difficult to forecast operating results and to make decisions about future investments. Future or continued economic weakness, failure of our customers and markets to recover from such weakness, customer financial difficulties, increases in costs of production, and reductions in spending on network maintenance and expansion could have a material adverse effect on demand for our products and consequently on our business, financial condition, and results of operations.

A limited number of our customers comprise a significant portion of our revenues and there is an ongoing trend toward consolidation in the industry in which our customers and partners operate. Any decrease in revenues from our customers or partners could have an adverse effect on our net revenues and operating results.

A substantial majority of our net revenues depend on sales to a limited number of customers and distribution partners. For example, AT&T and Verizon accounted for greater than 10% of our net revenues during the first quarter of 2013. Changes in the business requirements, vendor selection, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased) of our key customers could significantly decrease sales to such customers or could lead to delays or cancellations of planned purchases of our products or services, which increases the risk of quarterly fluctuations in our revenues and operating results. Any of these factors could adversely affect our business, financial condition, and results of operations.

In addition, in recent years, there has been movement towards consolidation in the telecommunications industry (for example, the acquisitions of Global Crossing by Level 3 Communications and Qwest Communications by CenturyLink and Softbank's purchase of a controlling interest in Sprint Nextel) and that consolidation trend has continued. If our customers or partners are parties to consolidation transactions they may delay, suspend or indefinitely reduce or cancel their purchases of our products or other unforeseen consequences could harm our business, financial condition, and results of operations.

The long sales and implementation cycles for our products, as well as our expectation that some customers will sporadically place large orders with short lead times, may cause our revenues and operating results to vary significantly from quarter-to-quarter.

A customer's decision to purchase certain of our products, particularly new products, involves a significant commitment of its resources and a lengthy evaluation and product qualification process. As a result, the sales cycle may be lengthy. In particular, customers making critical decisions regarding the design and implementation of large network deployments may engage in very lengthy procurement processes that may delay or impact expected future orders. Throughout the sales cycle, we may spend considerable time educating and providing information to prospective customers regarding the use and benefits of our products. Even after making the decision to purchase, customers may deploy our products slowly and deliberately. Timing of deployment

~~Table of Contents~~

can vary widely and depends on the skill set of the customer, the size of the network deployment, the complexity of the customer's network environment, and the degree of hardware and operating system configuration necessary to deploy the products. Customers with large networks usually expand their networks in large increments on a periodic basis. Accordingly, we may receive purchase orders for significant dollar amounts on an irregular basis. These long cycles, as well as our expectation that customers will tend to sporadically place large orders with short lead times, both of which may be exacerbated by the impact of continued global economic weakness, may cause revenues and operating results to vary significantly and unexpectedly from quarter-to-quarter.

We face intense competition that could reduce our revenues and adversely affect our business and financial results.

Competition is intense in the markets that we address. The PSD market has historically been dominated by Cisco, with competition coming from other companies such as Alcatel-Lucent, Brocade, Extreme Networks, Hewlett Packard Company, and Huawei. In the SSD market, we face intense competition from the above companies as well as companies such as Check Point, Cisco, F5 Networks, Fortinet, and Palo Alto Networks. Further, a number of other small public and private companies have products or have announced plans for new products to address the same challenges and markets that our products address.

In addition, actual or speculated consolidation among competitors, or the acquisition of our partners and/or resellers by competitors, can increase the competitive pressures faced by us as customers may delay spending decisions or not purchase our products at all. In this regard, in 2013, Oracle acquired Acme Packet, Inc., and Cisco acquired Meraki Networks, Inc. and ~~announced its proposed acquisition of~~ Sourcefire, Inc. A number of our competitors have substantially greater resources and can offer a wider range of products and services for the overall network equipment market than we do. If we are unable to compete successfully against existing and future competitors on the basis of product offerings or price, we could experience a loss in market share and revenues and/or be required to reduce prices, which could reduce our gross margins, and which could materially and adversely affect our business, financial condition, and results of operations.

Table of Contents

We expect our gross margins to vary over time, and the level of product gross margins achieved by us in recent years may not be sustainable.

We expect our product gross margins to vary from quarter-to-quarter, and the gross margins we have achieved in recent years may not be sustainable and may be adversely affected in the future by numerous factors, including customer, product and geographic mix shifts, increased price competition in one or more of the markets in which we compete, increases in material or labor costs, increases in inventory carrying costs, excess product component or obsolescence charges from our contract manufacturers, increased costs due to changes in component pricing or charges incurred due to component holding periods if we do not accurately forecast product demand, warranty related issues, or our introduction of new products or entry into new markets with different pricing and cost structures. For example, in the third quarter of fiscal 2012, our margins declined as a result of an inventory charge resulting from inventory we held in excess of forecasted demand. Failure to sustain or improve our gross margins reduces our profitability and may have a material adverse effect on our business and stock price.

IfTo the extent we receive product orders late in a quarter, we may be unable to recognize revenue for these orders in the same period, which could adversely affect our quarterly revenues.

Generally, our PSD products are not stocked by distributors or resellers due to their cost and complexity and configurations required by our customers, and we generally build such products as orders are received. In recent years, the volume of orders received late in any given fiscal quarter has generally continued to increase but remains unpredictable. If orders for certain products are received late in any quarter, we may not be able to build, ship, and recognize revenue for these orders in the same period, which could adversely affect our ability to meet our expected revenues for such quarter. Additionally, we determine our operating expenses largely on the basis of anticipated revenues and a high percentage of our expenses are fixed in the short and medium term. As a result, a failure or delay in generating or recognizing revenue could cause significant variations in our operating results and operating margin from quarter-to-quarter.

We are dependent on sole source and limited source suppliers for several key components, which makes us susceptible to shortages or price fluctuations in our supply chain, and we may face increased challenges in supply chain management in the future.

During periods of high demand for electronic products, component shortages are possible, and the predictability of the availability of such components may be limited. Any future growth in our business, IT spending and the economy in general is likely to create greater pressures on us and our suppliers to accurately forecast overall component demand and to establish optimal component inventories. If shortages or delays persist, the price of these components may increase, or the components

~~Table of Contents~~

may not be available at all. We may not be able to secure enough components at reasonable prices or of acceptable quality to build new products in a timely manner, and our revenues and gross margins could suffer until other sources can be developed. For example, from time to time, we have experienced component shortages that resulted in delays of product shipments. We currently purchase numerous key components, including ASICs, from single or limited sources. The development of alternate sources for those components is time-consuming, difficult, and costly. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. Also, long-term supply and maintenance obligations to customers increase the duration for which specific components are required, which may further increase the risk of component shortages or the cost of carrying inventory. In the event of a component shortage or supply interruption from these suppliers, we may not be able to develop alternate or second sources in a timely manner. If we are unable to buy these components in quantities sufficient to meet our requirements on a timely basis, we will not be able to deliver product to our customers, which would seriously affect present and future sales, which would, in turn, adversely affect our business, financial condition, and results of operations.

In addition, the development, licensing, or acquisition of new products in the future may increase the complexity of supply chain management. Failure to effectively manage the supply of key components and products would adversely affect our business.

We rely on value-added and other resellers, as well as distribution partners, to sell our products, and disruptions to, or our failure to effectively develop and manage, our distribution channel and the processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products.

Our future success is highly dependent upon establishing and maintaining successful relationships with a variety of value-added and other reseller and distribution partners, including our worldwide strategic partners such as Ericsson, IBM, and NSN. The majority of our revenues are derived through value-added resellers and distributors, most of which also sell our competitors’ products, and some of which sell their own products that compete with our products. Our revenues depend in part on the

Table of Contents

performance of these partners. The loss of or reduction in sales to our value-added resellers or distributors could materially reduce our revenues. For example, in 2006, one of our largest resellers, Lucent, was acquired by Alcatel, a competitor of ours. As a result of the merger, Lucent became a competitor, their resale of our products declined, and we ultimately terminated our reseller agreement with Lucent. Our competitors may in some cases be effective in leveraging their market share positions or in providing incentives to current or potential resellers and distributors to favor their products or to prevent or reduce sales of our products. If we fail to develop and maintain relationships with our partners, fail to develop new relationships with value-added resellers and distributors in new markets, or fail to expand the number of distributors and resellers in existing markets, fail to manage, train or motivate existing value-added resellers and distributors effectively, or if these partners are not successful in their sales efforts, sales of our products may decrease, and our business, financial condition, and results of operations would suffer.

In addition, we recognize a portion of our revenues based on a sell-through model using information provided by our distributors. If those distributors provide us with inaccurate or untimely information, the amount or timing of our revenues could be adversely impacted.

Further, in order to develop and expand our distribution channel, we must continue to offer attractive channel programs to potential partners and scale and improve our processes and procedures that support the channel. As a result, our programs, processes and procedures may become increasingly complex and inherently difficult to manage. We have previously entered into OEM agreements with partners pursuant to which they rebrand and resell our products as part of their product portfolios. These types of relationships are complex and require additional processes and procedures that may be challenging and costly to implement, maintain and manage. Our failure to successfully manage and develop our distribution channel and the programs, processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our products.

Our ability to process orders and ship products in a timely manner is dependent in part on our business systems and performance of the systems and processes of third parties such as our contract manufacturers, suppliers, or other partners, as well as the interfaces between our systems and the systems of such third parties. If our systems, the systems and processes of those third parties, or the interfaces between them experience delays or fail, our business processes and our ability to build and ship products could be impacted, and our financial results could be harmed.

Some of our business processes depend upon our information technology ("IT") systems, the systems and processes of third parties, and the interfaces of our systems with the systems of third parties. For example, our order entry system feeds information into the systems of our contract manufacturers, which enables them to build and ship our products. If those systems fail or are interrupted, our processes may function at a diminished level or not at all. This could negatively impact our ability to

~~Table of Contents~~

ship products or otherwise operate our business, and our financial results could be harmed. For example, although it did not adversely affect our shipments, an earthquake in late December of 2006 disrupted our communications with China, where a significant part of our manufacturing occurs. In addition, as discussed later in this "Risk Factors" section, in 2012 and continuing through 2013 and into 2014, we ~~expect to implement~~have been implementing major changes to our enterprise resource planning ("ERP") system.

We also rely upon the performance of the systems and processes of our contract manufacturers to build and ship our products. If those systems and processes experience interruption or delay, our ability to build and ship our products in a timely manner may be harmed. For example, we have experienced instances where our contract manufacturers were not able to ship products in the time periods expected by us. If we are not able to ship our products or if product shipments are delayed, our ability to recognize revenue in a timely manner for those products would be affected and our financial results could be harmed.

Telecommunications companies and our other large customers generally require onerous terms and conditions in our contracts with them. As we seek to sell more products to such customers, we may be required to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues.

Telecommunications service provider companies, which comprise a significant portion of our customer base, and other large companies, because of their size, generally have greater purchasing power than smaller entities and, accordingly, have requested and received more favorable terms from suppliers, which often translate into more onerous terms and conditions applicable to us. Recently, France Telecom-Orange and Deutsche Telekom AG have formed a company for the purpose of purchasing products from, and negotiating more favorable contractual terms with, suppliers. As we seek to sell more products to this class of customer, we may be required to agree to such terms and conditions, which may include terms that affect the timing of our ability to recognize revenue and have an adverse effect on our business, financial condition, and results of operations. Consolidation among such large customers can further increase their buying power and ability to require onerous terms.

Table of Contents

In addition, telecommunications service providers have purchased products from other vendors who promised but failed to deliver certain functionality and/or had products that caused problems or outages in the networks of these customers. As a result, these customers may request additional features from us and require substantial penalties for failure to deliver such features or may require substantial penalties for any network outages that may be caused by our products. These additional requests and penalties, if we are required to agree to them, may require us to defer revenue recognition from such sales, which may negatively affect our business, financial condition, and results of operations.

System security risks, data protection breaches, and cyber-attacks could compromise our proprietary information, disrupt our internal operations and harm public perception of our ~~security~~ products, which could cause our business and reputation to suffer and adversely affect our stock price.

In the ordinary course of business, we store sensitive data, including intellectual property, our proprietary business information and that of our customers, suppliers and business partners on our networks. The secure maintenance of this information is critical to our operations and business strategy. Increasingly, companies, including Juniper Networks, are subject to a wide variety of attacks on their networks on an ongoing basis. Despite our security measures, Juniper Networks' information technology and infrastructure may be vulnerable to penetration or attacks by computer programmers and hackers, or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks, creating system disruptions or slowdowns and exploiting security vulnerabilities of our products, and the information stored on our networks could be accessed, publicly disclosed, lost or stolen, which could subject us to liability to our customers, suppliers, business partners and others, and cause us reputational and financial harm. In addition, sophisticated hardware and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including "bugs" and other problems that could unexpectedly interfere with the operation of our networks.

If an actual or perceived breach of network security occurs in our network or in the network of a customer of our ~~security~~ products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness of our products could be harmed. Because the techniques used by computer programmers and hackers, many of whom are highly sophisticated and well-funded, to access or sabotage networks change frequently and generally are not recognized until after they are used, we may be unable to anticipate or immediately detect these techniques. This could impede our sales, manufacturing, distribution or other critical functions. In addition, the economic costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software systems and security vulnerabilities could be significant and may be difficult to anticipate or measure because the damage may differ based on the identity and motive of the programmer or hacker, which are often difficult to identify.

~~Table of Contents~~

Regulation of industry and the telecommunications industry in particular could harm our operating results and future prospects.

The Company is subject to laws and regulations affecting the sale of its products in a number of areas. For example, some governments have regulations prohibiting government entities from purchasing security products that do not meet specified indigenous certification criteria, even though those criteria may be in conflict with accepted international standards. Other regulations that may negatively impact the Company's business include country of origin regulations, such as the U.S. Securities and Exchange Commission's conflict minerals rule. These types of regulations are in effect or under consideration in several jurisdictions where we do business.

In addition, environmental regulations relevant to electronic equipment manufacturing or operations may impact our business and financial condition adversely. For instance, the European Union and China have adopted WEEE and ROHS regulations, which require producers of electrical and electronic equipment to assume responsibility for collecting, treating, recycling and disposing of products when they have reached the end of their useful life, as well as REACH regulations, which regulate handling of certain chemical substances that may be used in our products.

The traditional telecommunications industry is highly regulated, and our business and financial condition could be adversely affected by changes in regulations relating to the Internet telecommunications industry. Currently, there are few laws or regulations that apply directly to access to or commerce on IP networks, but future regulations could include sales taxes on products sold via the Internet and Internet service provider access charges. We could be adversely affected by regulation of IP networks and commerce in any country where we market equipment and services to service or content providers. Regulations governing the range of services and business models that can be offered by service providers or content providers could adversely affect those customers' needs for products designed to enable a wide range of such services or business models. For instance, the U.S. Federal Communications Commission has issued regulations governing aspects of fixed broadband networks and wireless networks; these regulations might impact service provider and content provider business models and as such,

Table of Contents

providers' needs for Internet telecommunications equipment and services. Also, many jurisdictions are evaluating or implementing regulations relating to cyber security, supply chain integrity, privacy and data protection, any of which can affect the market and requirements for networking and security equipment.

The adoption and implementation of such regulations could reduce demand for our products, increase the cost of building and selling our products, result in product inventory write-offs, impact our ability to ship products into affected areas and recognize revenue in a timely manner and require us to spend significant time and expense to comply, and we could face fines and civil or criminal sanctions or claims if we were to violate or become liable under such regulations. Any of these impacts could have a material adverse effect on our business, financial condition, and results of operations.

Governmental regulations affecting the import or export of products or affecting products containing encryption capabilities could negatively affect our revenues.

Certain of our products contain or use encryption technology. The United States and various foreign governments have imposed controls, export license requirements, and restrictions on the import or export, among other things, encryption technology. In addition, from time to time, governmental agencies have proposed additional regulation of encryption technology, such as requiring certification, notifications, review of source code, or the escrow and governmental recovery of private encryption keys. For example, Russia and China recently have implemented new requirements relating to products containing encryption and India has imposed special warranty and other obligations associated with technology deemed critical. Governmental regulation of encryption or IP networking technology and regulation of imports or exports, or our failure to obtain required import or export approval for our products, could harm our international and domestic sales and adversely affect our revenues. In addition, failure to comply with such regulations could result in harm to our reputation, penalties, costs, and restrictions on import or export privileges or adversely affect sales to government agencies or government-funded projects.

If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products and product enhancements that meet those technological shifts, needs and opportunities, or if those products are not made available in a timely manner or do not gain market acceptance, we may not be able to compete effectively and our ability to generate revenues will suffer.

We cannot guarantee that we will be able to anticipate future technological shifts, market needs and opportunities or be able to develop new products or product enhancements to meet such technological shifts, needs or opportunities in a timely manner or at all. For example, the move from traditional network infrastructures towards software defined networks ("SDN") has been receiving considerable attention. In our view, it will take several years to see the full impact of SDN, and we believe the

~~Table of Contents~~

successful products and solutions in this market will combine hardware and software elements together. If we fail to anticipate market requirements or fail to develop and introduce new products or product enhancements to meet those needs in a timely manner, it could cause us to lose customers, and such failure could substantially decrease or delay market acceptance and sales of our present and future products, which would significantly harm our business, financial condition, and results of operations. Even if we are able to anticipate, develop, and commercially introduce new products and enhancements, there can be no assurance that new products or enhancements will achieve widespread market acceptance.

In addition, ~~as a result of our acquisitions of Altor and Trapeze~~ in ~~2010, we have been offering a virtualization security product and a WLAN product. Also, in 2012,~~the past two years, we announced new products, including the ~~smaller version of our QFabric solutions, the latest~~ QFX3000-M QFabric System, T4000 Core ~~Routers,~~Router, EX9200 Ethernet Switch, PTX ~~Series~~3000 Packet Transport ~~switches, MX2020~~Router, and ~~MX2010 3D Universal Edge Routers and JunosV App Engine.~~Juniper Networks Contrail. If these or other new products do not gain market acceptance at a sufficient rate of growth, our ability to meet future financial targets may be adversely affected. In addition, if we fail to achieve market acceptance at a sufficient rate of growth, our ability to meet future financial targets and aspirations may be adversely affected. Finally, if we fail to deliver new or announced products to the market in a timely manner, it could adversely affect the market acceptance of those products and harm our competitive position and our business and financial results.

Our ability to develop, market, and sell products could be harmed if we are unable to retain or hire key personnel.

Our future success depends upon our ability to recruit and retain the services of executive, engineering, sales and marketing, and support personnel. The supply of highly qualified individuals, in particular engineers in very specialized technical areas, or sales people specializing in the service provider and enterprise markets, is limited and competition for such individuals is intense. None of our officers or key employees is bound by an employment agreement for any specific term. On July 24, 2013, our Chief Executive Officer, Kevin Johnson, announced that he will retire once a successor is named, and our board of directors has formed a search committee to identify his successor. The loss of the services of any of our key employees, the inability to attract or retain personnel in the future or delays in hiring required personnel, particularly a successor CEO, engineers and sales

people, and the complexity and time involved in replacing or training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell, or support our products.

We are a party to lawsuits, investigations, proceedings, and other disputes, which are costly to defend and, if determined adversely to us, could require us to pay damages or prevent us from taking certain actions, any or all of which could harm our business, financial condition, and results of operations.

We, and certain of our current and former officers and current and former members of our Board of Directors, are subject to various lawsuits. We have been served with lawsuits related to employment matters, commercial transactions and patent infringement as well as securities laws. A description of the securities lawsuits can be found in Note 16, Commitments and Contingencies,in Notes to Consolidated Financial Statements of this Report, under the heading “Legal Proceedings.” In addition, as noted under the heading of “Legal Proceedings”, the U.S. Securities and Exchange Commission and the U.S. Department of Justice are conducting investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act. We cannot predict the duration, scope, outcome or consequences of these investigations. There can be no assurance that these or any actions that have been or may in the future be brought against us, our officers, and our directors will be resolved favorably or that tentative settlements will become final. Regardless of whether they are resolved, these matters are, and any future lawsuits or threatened legal proceedings to which we, our officers, or our directors may become a party will likely be, expensive and time-consuming to defend, settle, and/or resolve. Legal proceedings, threatened legal proceedings or investigations, regardless of their ultimate outcome, could harm our reputation. Costs of investigation and defense, as well as any losses resulting from these claims or settlement of these matters, could significantly increase our expenses and could harm our business, financial condition, and results of operations.

We are a party to litigation and claims regarding intellectual property rights, resolution of which may be time-consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. Third parties have asserted and may in the future assert claims or initiate litigation related to patent, copyright, trademark, and other intellectual property rights to technologies and related standards that are relevant to our products. The asserted claims and/or initiated litigation may include claims against us or our manufacturers, suppliers, partners, or customers, alleging that our products or services infringe proprietary rights. Regardless of the merit of these claims, they have been and can be time-consuming, result in costly litigation, and may require us to develop non-infringing technologies or enter into license agreements. Furthermore, because of the potential for high awards of damages or injunctive relief that are not necessarily predictable, even arguably unmeritorious claims may be settled for significant amounts of money. If any infringement or other intellectual property claim made against us by any third-party is successful, if we are required to settle litigation for significant amounts of money, or if we fail to develop non-infringing technology or license required proprietary rights on commercially reasonable terms and conditions, our business, financial condition, and results of operations could be materially and adversely affected.

Our financial condition and results of operations could suffer if there is an additional impairment of goodwill or other intangible assets with indefinite lives.

We are required to test intangible assets with indefinite lives, including goodwill, annually and on an interim basis if an event occurs or there is a change in circumstance that would more likely than not reduce the fair value of reporting units and intangible assets below their carrying values. As of September 30, 2013, our goodwill was $4,057.7 million and there were no intangible assets with indefinite lives. When the carrying value of a reporting unit’s goodwill exceeds its implied fair value of goodwill, a charge to operations is recorded. If the carrying amount of an intangible asset with an indefinite life exceeds its fair value, a charge to operations is recognized. Either event would result in incremental expenses for that quarter, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred.

In the second quarter of 2006, our impairment evaluation resulted in a reduction of $1,280.0 million to the carrying value of goodwill on our Condensed Consolidated Balance Sheets, primarily due to the decline in our market capitalization that occurred over a period of approximately nine months prior to the impairment review and, to a lesser extent, to a decrease in forecasted future cash flows.

Table of Contents

In recent years, economic weakness has contributed to extreme price and volume fluctuations in global stock markets that have reduced the market price of many technology company stocks, including ours. Declines in our level of revenues or operating margins, as well as sustained declines in our stock price, increase the risk that goodwill and intangible assets with indefinite lives may become impaired in future periods.

During the three months ended September 30, 2013, we concluded that there were sufficient indicators to require us to perform an interim goodwill impairment analysis on our SSD segment. Based on our analysis, we determined that our SSD segment’s goodwill is not impaired. However, our analysis is sensitive to changes in key assumptions used in our analysis, such as expected future cash flows, the degree of volatility in equity and debt markets, and our stock price. If the assumptions used in our analysis are not realized, it is possible that an impairment charge may need to be recorded in the future. We cannot accurately predict the amount and timing of any impairment of goodwill or other intangible assets. However, any such impairment would have an adverse effect on our results of operations.

Changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our results.

Our future effective tax rates could be subject to volatility or adversely affected by: earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated earnings in countries where we have higher statutory rates; changes in the valuation of our deferred tax assets and liabilities; expiration of, or lapses in, the R&D tax credit laws applicable to us; transfer pricing adjustments related to certain acquisitions, including the license of acquired intangibles under our intercompany R&D cost sharing arrangement; costs related to intercompany restructuring; tax effects of share-based compensation; or changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our business, financial condition, and results of operations.

If we fail to accurately predict our manufacturing requirements, we could incur additional costs or experience manufacturing delays, which would harm our business.

We provide demand forecasts to our contract manufacturers and the manufacturers order components and plan capacity based on these forecasts. If we overestimate our requirements, our contract manufacturers may assess charges, or we may have liabilities for excess inventory, each of which could negatively affect our gross margins. For example, in the third quarter of fiscal 2012, our gross margins were reduced as a result of an inventory charge resulting from inventory we held in excess of forecasted demand. Conversely, because lead times for required materials and components vary significantly and depend on factors such as the specific supplier, contract terms, and the demand for each component at a given time, and because our contract manufacturers are third-party manufacturers for numerous other companies, if we underestimate our requirements, as we did in the third quarter of 2010 with respect to certain components, our contract manufacturers may have inadequate time, materials, and/or components required to produce our products, which could increase costs or could delay or interrupt manufacturing of our products and result in delays in shipments and deferral or loss of revenues.

~~Table of Contents~~

We are dependent on contract manufacturers with whom we do not have long-term supply contracts, and changes to those relationships, expected or unexpected, may result in delays or disruptions that could cause us to lose revenues and damage our customer relationships.

We depend on independent contract manufacturers (each of which is a third-party manufacturer for numerous companies) to manufacture our products. Although we have contracts with our contract manufacturers, these contracts do not require them to manufacture our products on a long-term basis in any specific quantity or at any specific price. In addition, it is time-consuming and costly to qualify and implement additional contract manufacturer relationships. Therefore, if we fail to effectively manage our contract manufacturer relationships, which includes failing to provide accurate forecasts of our requirements, or if one or more of them experiences delays, disruptions, or quality control problems in our manufacturing operations, or if we had to change or add additional contract manufacturers or contract manufacturing sites, our ability to ship products to our customers could be delayed. Also, the addition of manufacturing locations or contract manufacturers would increase the complexity of our supply chain management. Moreover, an increasing portion of our manufacturing is performed in China and other countries and is therefore subject to risks associated with doing business in other countries. In addition, in ~~late 2012,~~2013, we ~~confirmed that we were reducing~~reduced the number of our contract ~~manufacturers. As a result, we have been transitioning~~manufacturers and transitioned the work of one manufacturer to two of our other existing ~~manufacturers during 2013.~~manufacturers. If we do not manage ~~that~~the recent transition effectively, we could experience delays or quality issues. Each of these factors could adversely affect our business, financial condition and results of operations.

Upgrades to key internal systems and processes, and problems with the design or implementation of these systems and processes could interfere with, and therefore harm, our business and operations.

We previously initiated a multi-year project to upgrade certain key internal systems and processes, including our company-wide human resources management system, our customer relationship management (“CRM”) system and enterprise resource ERP system. In the first quarter of 2010, we implemented a major upgrade of our CRM system. In 2012 and continuing through 2013 and into 2014, we expect to implement major changes to our ERP system. We have invested, and will continue to invest, significant capital and human resources in the design and implementation of these systems and processes. Any disruptions or delays in the design and implementation of the new systems or processes, particularly any disruptions or delays that impact our operations, could adversely affect our ability to process customer orders, ship products, provide service and support to our customers, bill and track our customers, fulfill contractual obligations, record and transfer information in a timely and accurate manner, file SEC reports in a timely manner, or otherwise run our business. Even if we do not encounter these adverse effects, the design and implementation of these new systems and processes may be much more costly than we anticipated. If we are unable to successfully design and implement these new systems and processes as planned, or if the implementation of these systems and processes is more costly than anticipated, our business, financial condition, and results of operations could be negatively impacted.

We are a party to lawsuits, proceedings, and other disputes, which are costly to defend and, if determined adversely to us, could require us to pay damages or prevent us from taking certain actions, any or all of which could harm our business, financial condition, and results of operations.

We, and certain of our current and former officers and current and former members of our Board of Directors, are subject to various lawsuits. We have been served with lawsuits related to employment matters, commercial transactions and patent infringement as well as securities laws. A description of the securities lawsuits can be found in Note 16, ~~Commitments and Contingencies~~,in Notes to Consolidated Financial Statements of this Report, under the heading “Legal Proceedings.” There can be no assurance that these or any actions that have been or may in the future be brought against us, our officers, and our directors will be resolved favorably or that tentative settlements will become final. Regardless of whether they are resolved, these lawsuits are, and any future lawsuits or threatened legal proceedings to which we, our officers, or our directors may become a party will likely be, expensive and time-consuming to defend, settle, and/or resolve. Legal proceedings, threatened legal proceedings or investigations, regardless of their ultimate outcome, could harm our reputation. Costs of defense, as well as any losses resulting from these claims or settlement of these claims, could significantly increase our expenses and could harm our business, financial condition, and results of operations.

~~We are a party to litigation and claims regarding intellectual property rights, resolution of which may be time~~-~~consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.~~

~~Table of Contents~~

initiate litigation related to patent, copyright, trademark, and other intellectual property rights to technologies and related standards that are relevant to our products. The asserted claims and/or initiated litigation may include claims against us or our manufacturers, suppliers, partners, or customers, alleging that our products or services infringe proprietary rights. Regardless of the merit of these claims, they have been and can be time-consuming, result in costly litigation, and may require us to develop non-infringing technologies or enter into license agreements. Furthermore, because of the potential for high awards of damages or injunctive relief that are not necessarily predictable, even arguably unmeritorious claims may be settled for significant amounts of money. If any infringement or other intellectual property claim made against us by any third-party is successful, if we are required to settle litigation for significant amounts of money, or if we fail to develop non-infringing technology or license required proprietary rights on commercially reasonable terms and conditions, our business, financial condition, and results of operations could be materially and adversely affected.

We may face difficulties enforcing our proprietary rights.

We generally rely on a combination of patents, copyrights, trademarks, and trade secret laws and restrictions on disclosure of confidential and proprietary information, to establish and maintain proprietary rights in our technology and products. Although we have been issued numerous patents and other patent applications are currently now pending, there can be no assurance that any of these patents or other proprietary rights will not be challenged, invalidated, infringed or circumvented or that our rights will, in fact, provide competitive advantages to us or protect our technology, either of which could result in costly product redesign efforts, discontinuance of certain product offerings and other competitive harm. Furthermore, the laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States. The outcome of any actions taken in these foreign countries may be different than if such actions were determined under the laws of the United States. Although we are not dependent on any individual patents or group of patents for particular segments of the business for which we compete, if we are unable to protect our proprietary rights in a market, we may find ourselves at a competitive disadvantage to others who need not incur the substantial expense, time, and effort required to create innovative products that have enabled our success.

Our success depends upon our ability to effectively plan and manage our resources and restructure our business through rapidly fluctuating economic and market conditions.

Our ability to successfully offer our products and services in a rapidly evolving market requires an effective planning, forecasting, and management process to enable us to effectively scale and adjust our business in response to fluctuating market opportunities and conditions.

In periods of market expansion, we have increased investment in our business by, for example, increasing headcount and increasing our investment in R&D, sales and marketing, and other parts of our business.

Conversely, in the third quarter of 2012, to align our cost structure with long-term strategic plans as part of our productivity and efficiency initiatives, we restructured our business, rebalanced our workforce, and reduced our real estate portfolio. Many of our expenses, such as real estate expenses, are fixed costs that cannot be rapidly or easily adjusted in response to fluctuations in our business or numbers of employees. Moreover, rapid changes in the size of our workforce could adversely affect our ability to develop and deliver products and services as planned or impair our ability to realize our current or future business objectives. Our ability to achieve the anticipated cost savings and other benefits from our restructuring initiatives within the expected time frame is subject to many estimates and assumptions. These estimates and assumptions are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we are unsuccessful at implementing changes, or if other unforeseen events occur, our business and results of operations could be adversely affected.

~~Our financial condition and results of operations could suffer if there is an additional impairment of goodwill or other intangible assets with indefinite lives.~~

We are required to test annually and review on an interim basis, our goodwill and intangible assets with indefinite lives, including the goodwill associated with acquisitions, to determine if impairment has occurred. As of ~~June 30, 2013, our goodwill was~~ ~~$4,057.7 million~~ ~~and our intangible assets were~~ ~~$123.6 million~~. If goodwill or intangible assets are deemed impaired, an impairment loss equal to the amount by which the carrying amount exceeds the fair value of the assets would be recognized. This would result in incremental expenses for that quarter, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred. For example, such impairment could occur if the market value of our common stock falls below certain levels for a sustained period, or if the portions of our business related to companies we have acquired fail to grow at expected rates or decline. In the second quarter of 2006, our impairment evaluation resulted in a

~~Table of Contents~~

reduction of $1,280.0 million to the carrying value of goodwill on our Condensed Consolidated Balance Sheets, primarily due to the decline in our market capitalization that occurred over a period of approximately nine months prior to the impairment review and, to a lesser extent, a decrease in forecasted future cash flows. In the third quarter of 2012, our impairment evaluation resulted in a reduction of $5.4 million to the carrying value of certain purchased intangibles on our Condensed Consolidated Balance Sheets, primarily due to the decline in discounted cash flow projections. In recent years, economic weakness contributed to extreme price and volume fluctuations in global stock markets that reduced the market price of many technology company stocks, including ours. Future declines in our stock price, as well as declines in our level of revenues or gross margins, increase the risk that goodwill and intangible assets may become impaired in future periods. We cannot accurately predict the amount and timing of any impairment of assets. However, any such impairment would have an adverse effect on our results of operations.

We are subject to risks arising from our international operations, which may adversely affect our business, financial condition, and results of operations.

We derive a majority of our revenues from our international operations, and we plan to continue expanding our business in international markets in the future. We conduct significant sales and customer support operations directly and indirectly through

Table of Contents

our distributors and VARs in countries throughout the world and depend on the operations of our contract manufacturers and suppliers that are located outside of the United States. In addition, a portion of our R&D and our general and administrative operations are conducted outside the United States. In some countries, we may experience reduced intellectual property protection.

As a result of our international operations, we are affected by economic, regulatory, social, and political conditions in foreign countries, including the following:

changes in general IT ~~spending,~~spending;

the imposition of government controls, inclusive of critical infrastructure ~~protection,~~protection;

changes or limitations in trade protection laws or other regulatory requirements, which may affect our ability to import or export our products from various ~~countries,~~countries; and

the impact of the following on service provider and government spending patterns: political considerations, unfavorable changes in tax treaties or laws, natural disasters, epidemic disease, labor unrest, earnings expatriation restrictions, misappropriation of intellectual property, military actions, acts of terrorism, political and social unrest and difficulties in staffing and managing international operations.

Any or all of these factors could have a material adverse impact on our business, financial condition, and results of operations.

Moreover, local laws and customs in many countries differ significantly from those in the United States. In many foreign countries, particularly in those with developing economies, it is common for others to engage in business practices that are prohibited by our internal policies and procedures or United States regulations applicable to us. There can be no assurance that our employees, contractors, channel partners, and agents will not take actions in violation of our policies and procedures, which are designed to ensure compliance with U.S. and foreign laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners, or agents could result in termination of our relationship, financial reporting problems, fines, and/or penalties for us, or prohibition on the importation or exportation of our products, and could have a material adverse effect on our business, financial condition and results of operations.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.

Because a majority of our business is conducted outside the United States, we face exposure to adverse movements in non-U.S. currency exchange rates. These exposures may change over time as business practices evolve and could have a material adverse impact on our financial condition and results of operations.

The majority of our revenues and expenses are transacted in U.S. Dollars. We also have some transactions that are denominated in foreign currencies, primarily the British Pound, Euro, Indian Rupee, and Japanese Yen related to our sales and service operations outside of the United States. An increase in the value of the U.S. Dollar could increase the real cost to our customers of our products in those markets outside the United States in which we sell in U.S. Dollars, and a weakened U.S. Dollar could

~~Table of Contents~~

increase the cost of local operating expenses and procurement of raw materials to the extent we must purchase components in foreign currencies.

Currently, we hedge only those currency exposures associated with certain assets and liabilities denominated in nonfunctional currencies and periodically hedge anticipated foreign currency cash flows. The hedging activities undertaken by us are intended to offset the impact of currency fluctuations on certain nonfunctional currency assets and liabilities. However, such attempts to offset the impact of currency fluctuations are costly and no amount of hedging can be effective against all circumstances, including long-term declines in the value of the U.S. Dollar. If our attempts to hedge against these risks are not successful, or if long-term declines in the value of the U.S. Dollar persist, our financial condition and results of operations could be adversely impacted.

Integration of acquisitions could disrupt our business and harm our financial condition and stock price and may dilute the ownership of our stockholders.

We have made, and may continue to make, acquisitions in order to enhance our business. For example, in 2012, we acquired Contrail Systems Inc. ("Contrail") and Mykonos, and in 2010 we acquired Altor, Trapeze, SMobile, and Ankeena. Acquisitions

Table of Contents

involve numerous risks, including problems combining the purchased operations, technologies or products, unanticipated costs, diversion of management's attention from our core businesses, adverse effects on existing business relationships with suppliers and customers, risks associated with entering markets in which we have no or limited prior experience, and potential loss of key employees. There can be no assurance that we will be able to integrate successfully any businesses, products, technologies, or personnel that we might acquire. The integration of businesses that we may acquire is likely to be a complex, time-consuming, and expensive process and we may not realize the anticipated revenues or other benefits associated with our acquisitions if we fail to successfully manage and operate the acquired business. If we fail in any acquisition integration efforts and are unable to efficiently operate as a combined organization utilizing common information and communication systems, operating procedures, financial controls, and human resources practices, our business, financial condition, and results of operations may be adversely affected.

Acquisitions may also require us to issue common stock or assume equity awards that dilute the ownership of our current stockholders, use a substantial portion of our cash resources, assume liabilities, record goodwill and amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic impairment charges, incur amortization expenses related to certain intangible assets, and incur large and immediate write-offs and restructuring and other related expenses, all of which could harm our financial condition and results of operations.

If we fail to adequately evolve our financial and managerial control and reporting systems and processes, our ability to manage and grow our business will be negatively affected.

Our ability to successfully offer our products and implement our business plan in a rapidly evolving market depends upon an effective planning and management process. We will need to continue to improve our financial and managerial control and our reporting systems and procedures in order to manage our business effectively in the future. If we fail to continue to implement improved systems and processes, our ability to manage our business, financial condition, and results of operations may be negatively affected.

Our products are highly technical and if they contain undetected errors or malware or do not meet customer quality expectations, our business could be adversely affected, and we may be subject to lawsuits or be required to pay damages in connection with any alleged or actual failure of our products and services.

Our products are highly technical and complex, are critical to the operation of many networks, and, in the case of our security products, provide and monitor network security and may protect valuable information. Our products have contained and may contain one or more undetected errors, defects, malware, or security vulnerabilities. Some errors in our products may only be discovered after a product has been installed and used by end-customers. Any errors, defects, malware or security vulnerabilities discovered in our products after commercial release could result in monetary penalties, loss of revenues or delay in revenue recognition, loss of customers, loss of future business and reputation, penalties, and increased service and warranty cost, any of which could adversely affect our business, financial condition, and results of operations. In addition, in the event an error, defect, malware, or vulnerability is attributable to a component supplied by a third-party vendor, we may not be able to recover from the vendor all of the costs of remediation that we may incur. In addition, we could face claims for product liability, tort, or breach of warranty. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. If our business liability insurance coverage is inadequate, or future coverage is unavailable on acceptable terms or at all, our financial

~~Table of Contents~~

condition and results of operations could be harmed. Moreover, if our products fail to satisfy our customers' quality expectations for whatever reason, the perception of and the demand for our products could be adversely affected.

If our products do not interoperate with our customers’ networks, installations will be delayed or cancelled and could harm our business.

Our products are designed to interface with our customers’ existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. Many of our customers’ networks contain multiple generations of products that have been added over time as these networks have grown and evolved. Our products must interoperate with many or all of the products within these networks as well as future products in order to meet our customers’ requirements. If we find errors in the existing software or defects in the hardware used in our customers’ networks, we may need to modify our software or hardware to fix or overcome these errors so that our products will interoperate and scale with the existing software and hardware, which could be costly and could negatively affect our business, financial condition, and results of operations. In addition, if our products do not interoperate with those of our customers’ networks, demand for our products could be adversely affected or orders for our products could be cancelled. This could hurt our operating results, damage our reputation, and seriously harm our business and prospects.

Table of Contents

Our products incorporate and rely upon licensed third-party technology, and if licenses of third-party technology do not continue to be available to us or become very expensive, our revenues and ability to develop and introduce new products could be adversely affected.

We integrate licensed third-party technology into certain of our products. From time to time, we may be required to license additional technology from third-parties to develop new products or product enhancements. Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. The failure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements, could require us, if possible, to develop substitute technology or obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.

We sell our products to customers that use those products to build networks and IP infrastructure, and if the demand for network and IP systems does not continue to grow, then our business, financial condition, and results of operations could be adversely affected.

A substantial portion of our business and revenues depends on the growth of secure IP infrastructure and on the deployment of our products by customers that depend on the continued growth of IP services. As a result of changes in the economy capital spending or the building of network capacity in excess of demand, all of which have in the past particularly affected telecommunications service providers, spending on IP infrastructure can vary, which could have a material adverse effect on our business, financial condition, and results of operations. In addition, a number of our existing customers are evaluating the build-out of their next generation networks. During the decision-making period when the customers are determining the design of those networks and the selection of the equipment they will use in those networks, such customers may greatly reduce or suspend their spending on secure IP infrastructure. Such delays in purchases can make it more difficult to predict revenues from such customers can cause fluctuations in the level of spending by these customers and, even where our products are ultimately selected, can have a material adverse effect on our business, financial condition, and results of operations.

We are required to evaluate the effectiveness of our internal control over financial reporting, and any adverse results from such evaluation may adversely affect investor perception, our stock price and cause us to incur additional expense.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to report on, and our independent auditors to attest to, the effectiveness of our internal control over financial reporting. We have an ongoing program to perform the system and process evaluation and testing necessary to comply with these requirements. We have and will continue to incur significant expenses and devote management resources to Section 404 compliance on an ongoing basis. In the event that our Chief Executive Officer, Chief Financial Officer, or independent registered public accounting firm determine in the future that, our internal controls over financial reporting are not effective as defined under Section 404, investor perceptions may be adversely affected if our financial statements are not reliable and could cause a decline in the market price of our stock and otherwise negatively affect our liquidity and financial condition.

~~Table of Contents~~

The investment of our cash balance and our investments in government and corporate debt securities are subject to risks, which may cause losses and affect the liquidity of these investments.

As of ~~June~~September 30, 2013, we had $~~2,249.9~~2,271.5 million in cash and cash equivalents and $~~1,569.3~~1,762.3 million in short- and long-term investments. We have invested these amounts primarily in asset-backed securities, certificate of deposit, commercial paper, corporate debt securities, foreign government debt securities, government- sponsored enterprise obligations, money market funds, mutual funds, publicly-traded equity securities and U.S. government securities. Certain of these investments are subject to general credit, liquidity, market, sovereign debt, and interest rate risks. Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of our publicly traded debt or equity investments is judged to be other-than-temporary. These market risks associated with our investment portfolio may have a negative adverse effect on our liquidity, financial condition, and results of operations.

We may be unable to generate the cash flow to service our debt obligations, including the Senior Notes.

In March 2011, we issued senior unsecured notes for an aggregate principle amount of $1.0 billion (see discussion in Note 10, Long-Term Debt and Financing, in the Notes to Condensed Consolidated Financial Statements of this Report). We may not be able to generate sufficient cash flow to enable us to service our indebtedness, including the notes, or to make anticipated capital expenditures. Our ability to pay our expenses and satisfy our debt obligations, refinance our debt obligations and fund planned

Table of Contents

capital expenditures will depend on our future performance, which will be affected by general economic, financial, competitive, legislative, regulatory and other factors beyond our control. Based upon current levels of operations, we believe cash flow from operations and available cash will be adequate for the foreseeable future to meet our anticipated requirements for working capital, capital expenditures and scheduled payments of principal and interest on our indebtedness, including the senior notes. However, if we are unable to generate sufficient cash flow from operations or to borrow sufficient funds in the future to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt (including the senior notes) or obtain additional financing. There is no assurance that we will be able to refinance our debt, sell assets or borrow more money on terms acceptable to us, or at all.

The indenture that governs the senior notes also contains various covenants that limit our ability and the ability of our subsidiaries to, among other things:

incur liens;

incur sale and leaseback transactions; and

consolidate or merge with or into, or sell substantially all of our assets to, another ~~person~~person.

As a result of these covenants, we are limited in the manner in which we can conduct our business, and we may be unable to engage in favorable business activities or finance future operations or capital needs. Accordingly, these restrictions may limit our ability to successfully operate our business. A failure to comply with these restrictions could lead to an event of default, which could result in an acceleration of the indebtedness. Our future operating results may not be sufficient to enable compliance with these covenants to remedy any such default. In addition, in the event of an acceleration, we may not have or be able to obtain sufficient funds to make any accelerated payments, including those under the senior notes.

Uninsured losses could harm our operating results.

We self-insure against many business risks and expenses, such as intellectual property litigation and our medical benefit programs, where we believe we can adequately self-insure against the anticipated exposure and risk or where insurance is either not deemed cost-effective or is not available. We also maintain a program of insurance coverage for various types of property, casualty, and other risks. We place our insurance coverage with various carriers in numerous jurisdictions. The types and amounts of insurance that we obtain vary from time to time and from location to location, depending on availability, cost, and our decisions with respect to risk retention. The policies are subject to deductibles, policy limits, and exclusions that result in our retention of a level of risk on a self-insurance basis. Losses not covered by insurance could be substantial and unpredictable and could adversely affect our financial condition and results of operations.
