Basis of Presentation (Notes)
Basis of Presentation [Text Block]
Basis of Presentation

The unaudited Condensed Consolidated Financial Statements of Juniper Networks, Inc. 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 months ended March 31, 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 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 first quarter of 2013, the Company consolidated operational oversight and management of all security products within the Software Solutions Division ("SSD") segment. As a result of this product realignment, security products previously reported in the Platform Systems Division ("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. This change 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 subsequently NSN assumed the activities of the joint venture.

Summary of Significant Accounting Policies

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.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-02, Comprehensive Income (Topic 220)—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"), which amends FASB Accounting Standards Codification ("ASC") 220, Comprehensive Income to include the reporting of reclassifications from accumulated other comprehensive income to the respective line items in net income. The Company adopted ASU 2013-02 in the first quarter of 2013 and presented the effects within the Condensed Consolidated Statements of Comprehensive Income and the accompanying notes.

In December 2011, the FASB issued ASU No. 2011-11, Balance Sheet (Topic 210)—Disclosures About Offsetting Assets and Liabilities ("ASU 2011-11"), and in January 2013 issued ASU No. 2013-01, Balance Sheet (Topic 210)—Clarifying the Scope of Disclosures About Offsetting Assets and Liabilities ("ASU 2013-01"). These standards create new disclosure requirements regarding the nature of an entity's rights of setoff and related arrangements associated with its derivative instruments, repurchase agreements, and securities lending transactions. Disclosures of certain instruments subject to enforceable master netting arrangements would be required, irrespective of whether the entity has elected to offset those instruments in the statement of financial position. The Company adopted these standards during the first quarter of 2013 and presented the effects in the accompanying notes.
Business Combinations (Notes)
Business Combination [Text Block]
Business Combinations

During the three months ended March 31, 2013, the Company completed a business combination for approximately $10.0 million in cash consideration, of which $0.1 million was allocated to net tangible assets acquired and $9.9 million to intangible assets. The Company's consolidated financial statements include the operating results of this business combination from the date of acquisition, and the inclusion of those results were not material to its consolidated balance sheets and results of operations.

The Company recognized $0.1 million and $1.2 million of acquisition-related costs during the three months March 31, 2013 and 2012, respectively. These acquisition-related charges were expensed in the period incurred and reported as a component of acquisition and litigation charges in the Company's Condensed Consolidated Statements of Operations.

The Company had 134 and 98 investments in unrealized loss positions as of March 31, 2013 and December 31, 2012, respectively. The gross unrealized losses related to these investments were primarily due to changes in market interest rates and stock prices. The Company reviews its investments to identify and evaluate investments that have an indication of possible impairment. The Company aggregates its investments by category and length of time the securities have been in a continuous unrealized loss position to facilitate its evaluation. For the available-for-sale debt securities that have unrealized losses, the Company evaluates whether it (i) does not intend to sell any of these investments and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. For available-for-sale equity securities that have unrealized losses, the Company evaluates whether there is an indication of other-than-temporary impairments. This determination is based on several factors, including the financial condition and near-term prospects of the issuer and the Company's intent and ability to hold the publicly-traded equity securities for a period of time sufficient to allow for any anticipated recovery in market value. During the three months ended March 31, 2013 and 2012, the Company did not recognize other-than-temporary impairments associated with these investments.

There were no material gross realized gains or losses from available-for-sale and trading securities during the three months ended March 31, 2013 and 2012. Realized gains and losses are determined based on the specific identification method.

The following tables present the Company's available-for-sale investments that were in an unrealized loss position as of March 31, 2013 and December 31, 2012 (in millions):

Privately-Held Investments

As of March 31, 2013 and December 31, 2012, the carrying values of the Company’s privately-held investments of $39.2 million and $32.0 million, respectively, were included in other long-term assets in the Condensed Consolidated Balance Sheets.

The Company reviews its investments to identify and evaluate investments that have an indication of possible impairment. The Company adjusts its privately-held investments for any impairment if the fair value is less than the carrying value of the respective assets on an other-than-temporary basis.

During the three months ended March 31, 2012, the Company determined that certain privately-held investment were other-than-temporarily impaired, which resulted in impairment charges of $14.0 million and were recorded within other expense, net in the Condensed Consolidated Statements of Operations. There were no such charges during the three months ended March 31, 2013.

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 as of the actual date of the events or change in circumstances that caused the transfer. During the three months ended March 31, 2013 and March 31, 2012, the Company had no transfers between levels of the fair value hierarchy of its assets or liabilities measured at fair value.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

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. As of March 31, 2013 and December 31, 2012, the Company had no assets or liabilities measured at fair value on a nonrecurring basis.

Assets and Liabilities Not Measured at Fair Value

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).
Derivative Instruments (Notes)
Derivative Instruments [Text Block]
Derivative Instruments

Cash Flow Hedges

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 (loss) 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, 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 12 months.

As of March 31, 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 $1.6 million and $3.5 million, respectively. As of March 31, 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 $1.1 million and $0.1 million, respectively.

During the three months ended March 31, 2013 and March 31, 2012, the Company recognized a loss of $2.1 million and a gain of $6.0 million, respectively, in accumulated other comprehensive (loss) income for the effective portion of its derivative instruments and reclassified a gain of $1.4 million and a loss of $3.5 million, respectively, from other comprehensive income to operating expense in the Condensed Consolidated Statements of Operations.
The ineffective portion of the Company's derivative instruments recognized in its Condensed Consolidated Statements of Operations was not material during the three months ended March 31, 2013 and March 31, 2012.

Non-Designated Derivatives

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, 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.

The Company recognized a net loss of $0.7 million and $0.1 million, during the three months ended March 31, 2013 and March 31, 2012, respectively, on non-designated derivative instruments within other expense, net, in its Condensed Consolidated Statements of Operations.

Offsetting of Derivatives

The Company presents its derivative assets and derivative liabilities on a gross basis in the Condensed Consolidated Balance Sheets. However, under master netting agreements with certain counterparties of foreign exchange contracts, subject to applicable requirements, the Company is allowed to 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 March 31, 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 million and $0.1 million, respectively. The resulting net derivative assets and derivative liabilities of the potential offset impact are $1.4 million and $0.9 million as of March 31, 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 required to pledge nor is it entitled to receive cash collateral related to these derivative transactions.

Restructuring Charges (Notes)
Restructuring Charges [Text Block]
Restructuring Charges

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 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 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 or closures, and supply chain and procurement efficiencies. During the three months ended March 31, 2013, the Company continued to implement restructuring activities under the 2012 Restructuring Plan and recorded $7.8 million in charges for workforce reductions, facility consolidations or closures, and contract terminations. Under the 2012 Restructuring Plan, total costs incurred through March 31, 2013, was $101.1 million of which $53.6 million was recorded within cost of revenues and $47.5 million was recorded within restructuring charges in the Condensed Consolidated Statements of Operations. The Company expects to incur charges related to this plan through the end of fiscal 2013.

During 2011, the Company implemented a restructuring plan (the "2011 Restructuring Plan") in an effort to better align its business operations with the current market and macroeconomic conditions. The 2011 Restructuring Plan consisted of certain workforce reductions, facility closures and to a lesser extent, contract terminations. The Company recorded the majority of the restructuring charges associated with this plan during the years ended 2012 and 2011 and recorded severance-related adjustments of $0.1 million during the three months ended March 31, 2013. As of March 31, 2013, the remaining restructuring liability under this plan relates to facility charges, which are expected to be completed by March 2018.

The effective interest rates for the 2016 Notes, 2021 Notes, and 2041 Notes (collectively the “Notes”) include the interest on the Notes, accretion of the discount, and amortization of issuance costs. As of March 31, 2013 and December 31, 2012, the estimated fair value of the Notes included in long-term debt in the Condensed Consolidated Balance Sheets was approximately $1,074.3 million and $1,090.7 million, respectively, based on quoted market prices (Level 1). As of March 31, 2013, the Company was in compliance with all of its debt covenants.
 
Customer Financing Arrangements

The Company has customer financing arrangements to factor its accounts receivable to a third-party financing provider for certain customers that require longer payment terms than those typically provided by the Company. The program does not and is not intended to affect the timing of revenue recognition because the Company only recognizes revenue upon sell-through. Under the financing arrangements, proceeds from the financing provider are due to the Company 30 days from the sale of the receivable. In these transactions with the financing provider, the Company surrendered control over the transferred assets. The factored accounts receivable were isolated from the Company and put beyond the reach of creditors, even in the event of bankruptcy. The Company does not maintain effective control over the transferred assets through obligations or rights to redeem, transfer, or repurchase the receivables after they have been transferred.

Pursuant to the financing arrangements for the sale of receivables, the Company sold net receivables of $181.0 million and $120.6 million during the three months ended March 31, 2013 and March 31, 2012, respectively. The Company received cash proceeds from the financing provider of $162.7 million and $178.5 million during the three months ended March 31, 2013 and March 31, 2012, respectively. As of March 31, 2013 and December 31, 2012, the amounts owed by the financing provider were $159.2 million and $147.6 million, respectively, and were recorded in accounts receivable on the Company’s Condensed Consolidated Balance Sheets.

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 March 31, 2013 and December 31, 2012, the estimated cash received from the financing provider not recognized as revenue from distributors was $28.5 million and $30.7 million, respectively.

Stock Repurchase Activities

The Company currently has authority granted by the Board of Directors (the "Board") to repurchase up to $1.0 billion of its common stock under its stock repurchase program. As of March 31, 2013, there is $438.3 million of authorized funds remaining under the Company's stock repurchase program. In addition to repurchases under the Company’s stock repurchase program, the Company can also repurchase common stock from its employees in connection with net issuance of shares to satisfy minimum tax withholding obligations for the vesting of certain stock awards.

The Company repurchased and retired approximately 6.2 million shares of its common stock at an average price of $20.99 per share for an aggregate purchase price of $129.9 million during the three months ended March 31, 2013, under its stock repurchase program. The Company repurchased and retired approximately 2.4 million shares of its common stock at an average price of $21.75 per share for an aggregate purchase price of $51.6 million during the three months ended March 31, 2012 under its stock repurchase program. Repurchases associated to net issuances were not significant during the three months ended March 31, 2013 and March 31, 2012.

All shares of common stock repurchased under the Company's stock repurchase program and from its employees in connection with net issuance have been retired. Future share repurchases under the Company’s stock repurchase program will be subject to a review of the circumstances in place at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. This program may be discontinued at any time. See Note 17, Subsequent Events, for discussion of the Company's stock repurchase activity subsequent to March 31, 2013.

Employee Benefit Plans

Share-Based Compensation Plans

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"). 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 2006 Plan was adopted and approved by the Company’s stockholders in May 2006. To date, the Company's stockholders have approved a share reserve of 149.5 million shares of common stock plus the addition of any shares subject to options under the 2000 Plan and the 1996 Plan that were outstanding as of May 18, 2006, and that subsequently expire unexercised, up to a maximum of an additional 75.0 million shares. As of March 31, 2013, the 2006 Plan had 52.5 million shares subject to currently outstanding equity awards and 43.8 million shares available for future issuance.

The 2008 Purchase Plan 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 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) 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 March 31, 2013, approximately 11.4 million shares have been issued and 7.6 million shares remain available for future issuance under the 2008 Purchase Plan.

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 Networks' stock options, RSUs, and RSAs, respectively. No new stock options, RSUs, and RSAs can be granted under these plans. As of March 31, 2013, stock options, RSUs and RSAs representing approximately 6.6 million shares of common stock were outstanding under all awards assumed through the Company's acquisitions.

Segments (Notes)
Segments [Text Block]
Segments

The Company’s chief operating decision maker (“CODM”) allocates resources and assesses performance based on financial information of the Company’s divisions. 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. 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 SRX, firewall, vGW Virtual Gateways, 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, next generation network addressing, as well as the MobileNext architecture for mobile networks. Management and virtualization products include Junosphere, Junos SDK, JunosV App Engine and the network management platform, Junos Space.

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, net, income taxes, and certain other charges. Segment contribution margin excludes these corporate unallocated expenses.

During the three months ended March 31, 2013, AT&T and Verizon Communications, Inc. ("Verizon") accounted for 10.2% and 10.1% of net revenues, respectively. During the three months ended March 31, 2012, Verizon accounted for 12.2% of net revenues.

The Company tracks assets by physical location. The majority of the Company’s assets, excluding cash and cash equivalents and investments, as of March 31, 2013 and December 31, 2012, were attributable to U.S. operations. As of March 31, 2013 and December 31, 2012, gross property and equipment held in the U.S., as a percentage of total property and equipment, was approximately 83% for both periods. 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.
Income Taxes (Notes)
Income Tax [Text Block]
Income Taxes

The Company recorded a tax benefit of $14.1 million and a tax provision of $7.0 million, or effective tax rates of (18.3)% and 30.1% for the three months ended March 31, 2013 and March 31, 2012, respectively.

The effective tax rate for the three months ended March 31, 2013, reflects the Company's recognition of total tax benefits of approximately $43.0 million related to a tax settlement with the Internal Revenue Service (“IRS”) and the reinstatement of the U.S. federal research and development (“R&D”) tax credit on January 2, 2013.

In March 2013, 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 these tax years from 2004 through 2006. As a result of the settlement, the Company recognized a net tax benefit of $27.8 million, which included interest expense of $3.0 million. The Company is no longer subject to an audit of its U.S. federal income taxes through tax year 2006.

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. As a result, for the three months ended March 31, 2013, the Company recognized a tax benefit of $15.2 million related to fiscal 2012 R&D credits.

The effective tax rate for the three months ended March 31, 2012, differs from the federal statutory rate of 35% primarily due to the benefit of earnings in foreign jurisdictions, which are subject to lower tax rates, partially offset by an increase in the Company's valuation allowance attributable to investment losses currently disallowed for income tax purposes. The effective rate for the period does not reflect the benefit of the federal R&D credit which had expired on December 31, 2011.

As a result of the IRS tax settlement, the amount of gross unrecognized tax benefits was reduced by approximately $29.1 million. The total amount of gross unrecognized tax benefits was $111.2 million as of March 31, 2013, of which $98.2 million, if recognized, would affect the effective tax rate.

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 $11.1 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 currently under examination by the IRS for the 2007 through 2009 tax years. The Company is also subject to separate ongoing examinations by the India tax authorities for the 2004 tax year, 2004 through 2008 tax years and the 2009 through 2010 tax years. The Company is not aware of any other examinations by tax authorities in any other major jurisdictions in which it files income tax returns as of March 31, 2013.

In 2008, the Company received a proposed adjustment from the India tax authorities related to the 2004 tax year. In 2009, the India tax authorities commenced a separate investigation of our 2004 through 2008 tax returns and are disputing the Company's determination of taxable income due to the cost basis of certain fixed assets. The Company accrued $4.6 million in penalties and interest in 2009 related to this matter. The Company understands that in accordance with the administrative and judicial process in India, the Company may be required to make payments that are substantially higher than the amount accrued in order to ultimately settle this issue. The Company strongly believes that any assessment it may receive in excess of the amount accrued would be inconsistent with applicable India tax laws and intends to defend this position vigorously.
 
The Company is pursuing all available administrative procedures 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.”

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, ESPP issuances, and vesting of RSUs, RSAs, and PSAs.

The Company excludes both outstanding stock options with exercise prices that are greater than the average market price and RSUs and RSAs with grant date fair market value that are greater than the average market price from the calculation of diluted net income per share because their effect would be anti-dilutive. 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 24.7 million and 30.6 million shares were outstanding but were not included in the computation of diluted earnings per share for the three months ended March 31, 2013 and March 31, 2012, respectively.
Commitments and Contingencies (Notes)
Commitments and Contingencies [Text Block]
Commitments and Contingencies

Commitments

Operating Leases

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 $252.8 million as of March 31, 2013. Rent expense was $13.7 million and $15.7 million for the three months ended March 31, 2013 and March 31, 2012, respectively.

Purchase Commitments

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 $459.1 million as of March 31, 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 March 31, 2013, the Company accrued $24.0 million based on its estimate of such charges.

Long-Term Debt and Interest Payment on Long-Term Debt

As of March 31, 2013, the Company held long-term debt consisting of senior notes with a carrying value of $999.2 million. Of these Notes, $300.0 million will mature in 2016 and bears interest at a fixed rate of 3.10%, $300.0 million will mature in 2021 and bears interest at a fixed rate of 4.60%, and $400.0 million will mature in 2041 and bears interest at a fixed rate of 5.95%. Interest on the Notes is payable semiannually. See Note 10, Long-Term Debt and Financing, for further discussion of the Company's long-term debt.

Other Contractual Obligations

As of March 31, 2013, other contractual obligations primarily consisted of $94.4 million in indemnity-related and service related escrows, required by certain asset purchases and acquisitions completed in 2005, 2010, 2011, and 2012, campus build-out obligations of $47.5 million, and other miscellaneous commitments of $14.7 million.
Tax Liabilities

As of March 31, 2013, the Company had $87.1 million included in long-term incomes 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.

Guarantees

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, customs and duties guarantees, and standby letters of credit for certain lease facilities. As of March 31, 2013 and December 31, 2012, the Company had $11.7 million and $12.6 million, respectively, in bank guarantees and standby letters of credit related to these financial guarantees.

Legal Proceedings
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 not: recorded any accrual for loss contingencies associated with such legal proceedings; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.
2011 Federal Securities Class Action

On August 15, 2011, a purported securities class action lawsuit, captioned City of Royal Oak Retirement System v. Juniper Networks, Inc., et al., Case No. 11-cv-04003-LHK, was filed in the United States District Court for the Northern District of California naming the Company and certain of its officers and directors as defendants. The complaint alleges that the defendants made false and misleading statements regarding the Company's business and prospects. Plaintiffs seek an unspecified amount of monetary damages on behalf of the purported class. On January 9, 2012 the Court appointed City of Omaha Police and Fire Retirement System and City of Bristol Pension Fund as lead plaintiffs. Lead plaintiffs allege that defendants made false and misleading statements about the Company's business and future prospects, and failed to adequately disclose the impact of certain changes in accounting rules. Lead plaintiffs purport to assert claims for violations of Sections 10 (b), 20(a) and 20A of the Securities Exchange Act of 1934 and SEC Rule 10b-5 on behalf of those who purchased or otherwise acquired Juniper Networks' common stock between July 20, 2010 and July 26, 2011, inclusive. On March 14, 2012, Defendants filed motions to dismiss lead plaintiffs' amended complaint. On July 23, 2012, the Court issued an order dismissing the action and giving lead plaintiffs leave to file an amended complaint. Lead plaintiffs filed their second amended complaint on August 20, 2012. Defendants filed a motion to dismiss the second amended complaint on September 17, 2012, and lead plaintiffs filed their opposition on October 22, 2012. Defendants filed their reply brief on November 8, 2012. A hearing on the motion to dismiss is scheduled for May 16, 2013.

2011 California State Derivative Lawsuits

Between August 22 and September 9, 2011, four purported shareholder derivative actions were filed in the Superior Court of the State of California, County of Santa Clara, naming certain of the Company's officers and directors as defendants. The Company is named only as a nominal defendant in the actions. The actions were consolidated as In re Juniper Networks, Inc. Shareholder Litigation, Case No. 1-11-CV-207701 (Lead Case), by order dated September 12, 2011. The complaints are generally based upon the disclosures and alleged omissions challenged in the securities class action. The complaints purport to assert claims against the defendants for breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The complaints seek, among other relief, damages in an unspecified amount, restitution, and attorneys' fees and costs. On March 8, 2012, the Company filed a motion to stay the action until resolution of the federal securities class action discussed above, and also filed a demurrer seeking to dismiss the action for the reason that plaintiffs lack standing. The plaintiffs filed oppositions to both motions on April 5, 2012. Defendants filed reply briefs on May 7, 2012. At a hearing on July 27, 2012, the Court ordered that the actions be stayed until such time as the federal court issues an order denying a motion to dismiss in the securities class action, City of Omaha Police and Fire Retirement System v. Juniper Networks, Inc. et al., Case No. CV-11-4003-LHK. The Court deferred deciding the demurrer pending the stay.
2011 Federal Derivative Lawsuit
On September 27, 2011 and December 28, 2011, two purported shareholder derivative actions, captioned Ratinova v. Johnson, et al., Case No. 11-cv-04792 and Lisa E. Coppola, ERA v. Johnson, et al., Case No. 11-cv-06667, respectively, were filed in the United States District Court for the Northern District of California naming certain of the Company's officers and directors as defendants. The Company is named only as a nominal defendant in the action. Like the state derivative actions, the federal derivative lawsuits are generally based upon the disclosures and alleged omissions challenged in the securities class action. The complaints purport to assert claims against the defendants for breach of fiduciary duties and unjust enrichment. The complaints seek, among other relief, damages in an unspecified amount, restitution, and attorneys' fees and costs. By order dated January 30, 2012, the Court consolidated the actions as In re Juniper Networks, Inc. Shareholder Derivative Litigation, Master File No. 11-cv-04792-LHK. On February 3, 2012, the parties filed a stipulation in which the parties requested that the Court stay the action until such time as the Court entered an order denying a motion to dismiss in the related federal securities class action described above. On February 6, 2012, the Court granted the parties' stipulation.

IRS Notices of Proposed Adjustments

The Company is currently under examination by the IRS for the 2007 through 2009 tax years.

In March 2013, the Company executed a closing agreement with the Appeals Division of the IRS related to its intercompany R&D cost sharing arrangement for the license of intangibles acquired in 2004, 2005 and 2006. The Company reached a final resolution with the IRS on all proposed adjustments for all tax years through 2006, which resulted in a settlement of approximately $20.9 million, including interest.

Summary of Significant Accounting Policies (Policies)
Recent Accounting Pronouncements
Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-02, Comprehensive Income (Topic 220)—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"), which amends FASB Accounting Standards Codification ("ASC") 220, Comprehensive Income to include the reporting of reclassifications from accumulated other comprehensive income to the respective line items in net income. The Company adopted ASU 2013-02 in the first quarter of 2013 and presented the effects within the Condensed Consolidated Statements of Comprehensive Income and the accompanying notes.

In December 2011, the FASB issued ASU No. 2011-11, Balance Sheet (Topic 210)—Disclosures About Offsetting Assets and Liabilities ("ASU 2011-11"), and in January 2013 issued ASU No. 2013-01, Balance Sheet (Topic 210)—Clarifying the Scope of Disclosures About Offsetting Assets and Liabilities ("ASU 2013-01"). These standards create new disclosure requirements regarding the nature of an entity's rights of setoff and related arrangements associated with its derivative instruments, repurchase agreements, and securities lending transactions. Disclosures of certain instruments subject to enforceable master netting arrangements would be required, irrespective of whether the entity has elected to offset those instruments in the statement of financial position. The Company adopted these standards during the first quarter of 2013 and presented the effects in the accompanying notes.
