Description of Business and Basis of Presentation

Description of Business

Juniper Networks, Inc. (the “Company” or “Juniper”) designs, develops, and sells products and services that together provide customers with a high-performance network infrastructure built on simplicity, security, openness, and scale. The Company serves 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.

Basis of Presentation

The consolidated financial statements, which include the Company and its wholly-owned subsidiaries, are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). All inter-company balances and transactions have been eliminated. Certain amounts in the prior year Consolidated Financial Statements have been reclassified to conform to the current year presentation.

Beginning in the first quarter of 2012, the Company aligned its organizational structure to focus on its platform and software strategy, which resulted in two reportable segments organized principally by product families: Platform Systems Division ("PSD") and Software Solutions Division ("SSD"). The Company has reclassified the segment data for the prior periods to conform to the current period's presentation. The segment 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 segment reorganization.

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 have been consolidated with the accounts of the Company, and a noncontrolling interest has been 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 terminate the joint venture and subsequently NSN assumed the activities of the joint venture. The Company terminated the joint venture during the first quarter of 2013 and the termination is not expected to have a material effect on the Company's financial position or results of operations.

Use of Estimates
 
The preparation of the financial statements and related disclosures in conformity with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. To the extent there are material differences between the Company's estimates and the actual results, the Company's future consolidated results of operation may be affected.
 
Fair Value

Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it transacts, and considers assumptions that market participants would use when pricing the asset or liability. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

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

Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. These inputs are valued using market based approaches.

Level 3 – Inputs are unobservable inputs based on the Company’s assumptions. These inputs, if any, are valued using internal financial models.

Cash, Cash Equivalents and Investments
 
Cash and Cash Equivalents

All highly liquid investments purchased with a remaining maturity of three months or less are classified as cash and cash equivalents. Cash and cash equivalents consist of cash on hand, demand deposits with banks, highly liquid investments in money market funds, commercial paper, government securities, certificates of deposit, and corporate debt securities, which are readily convertible into cash.

Investments in Available-for-Sale and Trading Securities

The Company's investments in publicly-traded debt and equity securities are classified as available-for-sale. Available-for-sale investments are initially recorded at cost and periodically adjusted to fair value in the consolidated balance sheets. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss). Realized gains and losses are determined based on the specific identification method and are reported in the consolidated statements of operations.

The Company recognizes an impairment charge for available-for-sale investments when a decline in the fair value of its investments below the cost basis is determined to be other than temporary. The Company considers various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value has been less than the Company's cost basis, the investment's financial condition, and near-term prospects of the investee. If the Company determines that the decline in an investment's fair value is other than temporary, the difference is recognized as an impairment loss in its Consolidated Statements of Operations.

The Company's non-qualified compensation plan, which invests in mutual funds are classified as trading securities and reported at fair value in the Consolidated Balance Sheets. The realized and unrealized holding gains and losses are reported in the Consolidated Statements of Operations.
 
Privately-Held Investments
 
The Company has investments in privately-held companies. These investments are included in other long-term assets in the Consolidated Balance Sheets and are carried at cost, adjusted for any impairment, as the Company does not have a controlling interest and does not have the ability to exercise significant influence over these companies. These investments are inherently high risk as the market for technologies or products manufactured by these companies are usually early stage at the time of the investment by the Company and such markets may never be significant. The Company measures the fair value of privately-held investments using an analysis of the financial conditions and near term prospects of the investees, including recent financing activities and their capital structure. Realized gains and losses, if any, are reported in the Consolidated Statements of Operations.

Derivatives
 
The Company uses derivatives to partially offset its market exposure to fluctuations in certain foreign currencies. The Company does not enter into derivatives for speculative or trading purposes.
 
The Company uses foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement of certain monetary assets and liabilities denominated in non-functional currencies. These derivatives are carried at fair value with changes recorded in other (expense) income, net. 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. These foreign exchange forward contracts have maturities of one year or less.
The Company also uses foreign currency forward or option contracts to hedge certain forecasted foreign currency transactions relating to operating expenses. These derivatives are designated as cash flow hedges and have maturities of less than one year. These derivatives are carried at fair value and the effective portion of the derivative's gain or loss is initially reported as a component of accumulated other comprehensive income (loss), and upon occurrence of the forecasted transaction, is subsequently reclassified into the operating expense line item to which the hedged transaction relates. The Company records any ineffectiveness of the hedging instruments, which was immaterial during 2012, 2011, and 2010, in other (expense) income, net, on its Consolidated Statements of Operations. Cash flows from such hedges are classified as operating activities.

Concentrations
 
Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments, and accounts receivable. The Company invests only in high-quality credit instruments and maintains its cash, cash equivalents and available-for-sale investments in fixed income securities with several high-quality institutions. Deposits held with banks, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand and, therefore, bear minimal risk.
 
Generally, credit risk with respect to accounts receivable is diversified due to the number of entities comprising the Company's customer base and their dispersion across different geographic locations throughout the world. The Company performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. The Company maintains reserves for potential bad debt and historically such losses have been within management's expectations. During the years ended December 31, 2012 and 2010, Verizon Communications, Inc. ("Verizon") accounted for 10.3% and 10.4% of net revenues, respectively. During the year ended December 31, 2011, no single customer accounted for 10% or more of net revenues.
 
The Company relies on sole suppliers for certain of its components such as ASICs and custom sheet metal. Additionally, the Company relies primarily on a limited number of significant independent contract manufacturers for the production of all of its products. The inability of any supplier or manufacturer to fulfill supply requirements of the Company could negatively impact future operating results.
 
Inventory
Inventory consists primarily of component parts to be used in the manufacturing process and is stated at the lower of average cost or market. A provision is recorded when inventory is determined to be in excess of anticipated demand or obsolete, to adjust inventory to its estimated realizable value.

Property and Equipment
 
Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets of one and half years to five years for computers, equipment and software, five years for furniture and fixtures, seven to forty years for building and building improvements, and ten to forty years for land improvements. Leasehold improvements are amortized using the straight-line method over lease term, for a maximum of ten years. Construction in progress is related to the construction or development of property and equipment that have not yet been placed in service for their intended use. Depreciation for equipment commences once it is placed in service and depreciation for buildings and leasehold improvements commences once they are ready for their intended use.
 
Goodwill and Other Long-Lived Assets
 
Goodwill represents the future economic benefits arising from other assets acquired in a business combination or an acquisition that are not individually identified and separately recorded. The excess of the purchase price over the estimated fair value of net assets of businesses acquired in a business combination is recognized as goodwill. Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually during the fourth quarter. Such goodwill and other intangible assets may also be tested for impairment between annual tests in the presence of impairment indicators such as, but not limited to: (a) a significant adverse change in legal factors or in the business climate; (b) a substantial decline in our market capitalization, (c) an adverse action or assessment by a regulator; (d) unanticipated competition; (e) loss of key personnel; (f) a more likely-than-not expectation of sale or disposal of a reporting unit or a significant portion thereof; (g) a realignment of our resources or restructuring of our existing businesses in response to changes to industry and market conditions; (h) testing for recoverability of a significant asset group within a reporting unit; or (i) higher discount rate used in the impairment analysis as impacted by an increase in interest rates.

The Company performs its annual goodwill impairment analysis at its reporting unit level, which is one level below its operating segment level during the fourth quarter of each year. The fair value of the Company's reporting units is determined using both the income and market valuation approaches. Under the income approach, the fair value of the reporting unit is based on the present value of estimated future cash flows that the reporting unit is expected to generate over its remaining life. Under the market approach, the value of the reporting unit is based on an analysis that compares the value of the reporting unit to values of publicly traded companies in similar lines of business. In the application of the income and market valuation approaches, the Company is required to make estimates of future operating trends and judgments on discount rates and other variables. Actual future results related to assumed variables could differ from these estimates.

Long-lived assets, such as property, plant, and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Such events or circumstances include, but are not limited to, a significant decrease in the fair value of the underlying business, a significant decrease in the benefits realized from an acquired business, difficulties or delays in integrating the business or a significant change in the operations of an acquired business. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group, to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. An impairment charge is recognized by the amount by which the carrying amount of the asset, or asset group, exceeds its fair value.

The Company amortizes intangible assets with estimable useful lives on a straight-line basis over their useful lives.

Revenue Recognition
 
Revenue is recognized when all of the following criteria have been met:

•
Persuasive evidence of an arrangement exists.  The Company generally relies upon sales contracts or agreements, and customer purchase orders to determine the existence of an arrangement.

•
Delivery has occurred.  The Company uses shipping terms and related documents, or written evidence of customer acceptance, when applicable, to verify delivery or performance.

•
Sales price is fixed or determinable.  The Company assesses whether the sales price is fixed or determinable based on the payment terms and whether the sales price is subject to refund or adjustment.

•
Collectability is reasonably assured.  The Company assesses collectability based on creditworthiness of customers as determined by our credit checks and their payment histories. The Company records accounts receivable net of allowance for doubtful accounts, estimated customer returns, and pricing credits.
 
When sales arrangements contain multiple elements and software and non-software components that function together to deliver the tangible products' essential functionality, the Company allocates revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on either vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) if VSOE is not available, or estimated selling price (“ESP”) if neither VSOE nor TPE is available. The Company then recognizes revenue on each deliverable in accordance with its policies for product and service revenue recognition. VSOE of selling price is based on the price charged when the element is sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices fall within a reasonable range based on historical discounting trends for specific products and services. TPE of selling price is established by evaluating largely interchangeable competitor products or services in stand-alone sales to similarly situated customers. However, as the Company's products contain a significant element of proprietary technology and its solutions offer substantially different features and functionality, the comparable pricing of third-party products with similar functionality typically cannot be obtained. ESP is established considering multiple factors including, but not limited to pricing practices in different geographies and through different sales channels, gross margin objectives, internal costs, competitor pricing strategies, and industry technology lifecycles.

In multiple element arrangements where software deliverables are included, revenue is allocated to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. If the arrangement contains more than one software deliverable, the arrangement consideration allocated to the software deliverables as a group is then allocated to each software deliverable using the residual method when VSOE of fair value of the undelivered items exists. Under the residual method, the amount of revenue allocated to delivered elements equals the total arrangement consideration less the aggregate fair value of any undelivered elements. If VSOE of one or more undelivered items does not exist, revenue from the entire arrangement is deferred and recognized at the earlier of: (i) delivery of those elements or (ii) when fair value can be established unless maintenance is the only undelivered element, in which case, the entire arrangement fee is recognized ratably over the contractual support period.

The Company limits the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services or subject to customer-specific return or refund privileges.

The Company records reductions to revenue for estimated product returns and pricing adjustments, such as rebates and price protection, in the same period that the related revenue is recorded. The amount of these reductions is based on historical sales returns and price protection credits, specific criteria outlined in rebate agreements, and other factors known at the time. A portion of the Company's sales is made through distributors under agreements allowing for pricing credits or rights of return. Product revenue on sales made through these distributors is recognized upon sell-through as reported by the distributors to the Company. Deferred revenue on shipments to distributors reflects the effects of distributor pricing credits and the amount of gross margin expected to be realized upon sell-through. Deferred revenue is recorded net of the related product costs of revenue.
 
Service revenues include revenue from maintenance, training, and professional services. Maintenance is offered under renewable contracts. Revenue from maintenance service contracts is deferred and recognized ratably over the contractual support period, which is generally one to three years. Revenue from training and professional services is recognized as services are completed or ratably over the contractual period, which is generally one year or less.
 
The Company sells certain interests in accounts receivable on a non-recourse basis as part of customer financing arrangements primarily with one major financing company. Cash received under this arrangement in advance of revenue recognition is recorded as a secured borrowing within other current liabilities.
 
Allowance for Doubtful Accounts
 
The allowance for doubtful accounts is based on the Company's assessment of the collectability of customer accounts. The Company regularly reviews its receivables that remain outstanding past their applicable payment terms and establishes an allowance by considering factors such as historical experience, credit quality, age of the accounts receivable balances, and current economic conditions that may affect a customer's ability to pay.
 
Warranty Reserves
 
The Company generally offers a one-year warranty on all of its hardware products and a 90-day warranty on the media that contains the software embedded in the products. Warranty costs are recognized as part of the Company's cost of sales based on associated material costs, labor costs, and overhead at the time revenue is recognized. Material costs are estimated primarily based upon the historical costs to repair or replace product returns within the warranty period. Labor and overhead costs are estimated primarily based upon historical trends in the cost to support customer cases within the warranty period.
 
Contract Manufacturer Liabilities
 
The Company establishes a liability for non-cancelable, non-returnable ("NCNR") purchase commitments with its contract manufacturers for carrying charges, quantities in excess of its demand forecasts, or obsolete material charges for components purchased by the contract manufacturers to meet the Company’s demand forecast or customer orders. The demand forecasts are based upon historical trends and analysis from the Company's sales and marketing organizations, adjusted for overall market conditions.

Research and Development
 
Costs to research, design, and develop the Company's products are expensed as incurred. Software development costs are capitalized beginning when a product's technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company's products are released soon after technological feasibility has been established. As a result, costs incurred between achieving technological feasibility and product general availability have not been significant.
 
Advertising
 
Advertising costs are charged to sales and marketing expense as incurred. Advertising expense was $20.0 million, $17.2 million, and $17.1 million, for 2012, 2011, and 2010, respectively.

Foreign Currency Translations
 
Assets and liabilities of foreign operations with non-U.S. Dollar functional currency are translated to U.S. Dollars using exchange rates in effect at the end of the period. Revenue and expenses are translated to U.S. Dollars using average exchange rates for the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets in the stockholders’ equity section as a component of accumulated other comprehensive income (loss).
 
Loss Contingencies
 
The Company is subject to the possibility of various loss contingencies arising in the ordinary course of business. Management considers the likelihood of loss related to an asset, or the incurrence of a liability, as well as its ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted and whether new accruals are required.
  
Share-Based Compensation

The Company utilizes the Black-Scholes-Merton (“BSM”) option-pricing model to estimate the fair value of its stock options and ESPP shares. The Company determines the fair value of its restricted stock units ("RSUs"), restricted stock awards ("RSAs"), and performance share awards ("PSAs") based on the closing market price of the Company’s common stock on the date of grant. Share-based compensation expense is based on the fair value the underlying awards and amortized on a straight-line basis, net of estimated forfeitures. With respect to PSAs, that generally vest after three years, for the portion of the award attributable to each performance year, the Company recognizes PSA expense on a straight-line basis over the remaining vesting period starting in the period in which the annual performance targets are set for each such performance year.

The BSM model requires various highly subjective assumptions that represent management's best estimates of volatility, risk-free interest rate, expected life, and dividend yield. The expected volatility is based on the implied volatility of market-traded options on the Company's common stock, adjusted for other relevant factors including historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options. The expected life of a stock option award is based on historical experience.

Provision for Income Taxes
 
Income tax expense is based on pretax financial accounting income. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized.
The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2013-02, Topic 350 - Comprehensive Income ("ASU 2013-02"), which amends Topic 220 to improve the reporting of reclassifications out of accumulated other comprehensive income to the respective line items in net income. ASU 2013-02 is effective for reporting periods beginning after December 15, 2012. The Company intends to adopt this standard in the first quarter of 2013 and does not expect the adoption will have a material impact on its consolidated results of operations or financial condition.

In July 2012, the FASB issued ASU No. 2012-02, Topic 350 - Intangibles - Goodwill and Other ("ASU 2012-02"), which amends Topic 350 to allow an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value. An entity would not be required to determine the fair value of the indefinite-lived intangible unless the entity determines, based on the qualitative assessment, that it is more likely than not that its fair value is less than the carrying value. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 and early adoption is permitted. The Company intends to adopt this standard in the first quarter of 2013 and does not expect the adoption will have an impact on its consolidated results of operations or financial condition.

The Company recognized $2.0 million, $9.6 million, and $6.3 million of acquisition-related costs during the years ended December 31, 2012, 2011, and 2010, respectively. These acquisition-related charges were expensed in the period incurred and reported in the Company's Consolidated Statements of Operations within cost of revenues and operating expense.

The goodwill recognized for the 2012 and 2011 acquisitions was primarily attributable to expected synergies and was not deductible for U.S. federal income tax purposes. Approximately $88.9 million of the acquired goodwill from a 2010 acquisition was deductible for income tax purposes.

Fiscal 2012 Acquisitions

Contrail Systems Inc.

On December 14, 2012, the Company acquired the remaining ownership interest in Contrail Systems, Inc. ("Contrail"), increasing its ownership from 12% to 100%, in a cash and stock transaction for approximately $91.7 million.

Acquired in-process research and development (“IPR&D”) consists of existing research and development projects at the time of the acquisition. Projects that qualify as IPR&D assets represent those that have not yet reached technological feasibility and have no alternative future use. After initial recognition, acquired IPR&D assets are accounted for as indefinite-lived intangible assets. Development costs incurred after acquisition on acquired development projects are expensed as incurred. Upon completion of development, acquired IPR&D assets are considered amortizable intangible assets. If the IPR&D project is abandoned, the Company writes off the related purchased intangible asset in the period it is abandoned.

The Company had 98 and 135 investments in unrealized loss positions as of December 31, 2012 and December 31, 2011, respectively. The gross unrealized losses related to these investments were primarily due to changes in market interest rates. 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 determines that (i) it does not have the intent 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. In addition, as of December 31, 2012, the Company anticipates that it will recover the entire amortized cost basis of such available-for-sale debt securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the year ended December 31, 2012, 2011, and 2010. For available-for-sale equity securities that have unrealized losses, the Company determined that there was no indication of other-than-temporary impairments as of December 31, 2012. This determination was 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 years December 31, 2012, 2011, and 2010, the Company did not recognize other-than-temporary impairments associated with these investments.

Restricted Cash and Investments

The Company classifies cash and investments as restricted cash and investments on its Consolidated Balance Sheets and designated as available for sale securities for: (i) amounts held in escrow accounts, as required by certain acquisitions completed between 2005 and 2012; (ii) the India Gratuity Trust and Israel Retirement Trust, which cover statutory severance obligations in the event of termination of any of the Company's India and Israel employees, respectively; and (iii) the Directors and Officers ("D&O") indemnification trust.

Privately-Held Investments

As of December 31, 2012 and December 31, 2011, the carrying values of the Company’s privately-held investments of $32.0 million and $51.8 million, respectively, were included in other long-term assets in the 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 years ended December 31, 2012 and December 31, 2011, the Company determined that certain privately-held investments were other-than-temporarily impaired, which resulted in impairment charges of $20.0 million and $1.8 million, respectively, and were recorded within other (expense) income, net in the Consolidated Statements of Operations. In 2010, the Company determined there were no impairments to its privately-held investments.

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 years ended December 31, 2012 and December 31, 2011, 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.
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 the investments. The Company measured 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 year ended December 31, 2012, privately-held investments with a carrying value of $20.0 million were measured at fair value resulting in an impairment charge of $20.0 million. During the year ended December 31, 2011, privately-held investments with a carrying value of $2.2 million were measured at fair value resulting in an impairment charge of $1.8 million. These investments were classified as Level 3 assets due to the absence of quoted market prices and inherent lack of liquidity. During the year ended December 31, 2010, privately-held investments with a carrying value of $0.8 million were measured at fair value, but did not result in an impairment charge.
During the year ended December 31, 2012, certain purchased intangible assets with a carrying value of $5.4 million were measured at fair value resulting in an impairment charge of $5.4 million and recorded within cost of revenues on the Consolidated Statements of Operations. The Company measured the fair value of these assets primarily using discounted cash flow projections. Purchased intangible assets were classified as Level 3 assets, due to the absence of quoted market prices. See Note 7, Goodwill and Purchased Intangibles Assets, for further information. There were no such assets measured at fair value on a nonrecurring basis during the year ended December 31, 2011 and December 31, 2010.
The Company had no liabilities measured at fair value on a nonrecurring basis during December 31, 2012 and 2011, and 2010.

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).

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 income (loss), 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 income, net in its 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 December 31, 2012 and December 31, 2011, the total fair value of the Company’s derivative assets recorded in other current assets on the Consolidated Balance Sheets was $3.5 million and $0.4 million, respectively. As of December 31, 2012 and December 31, 2011, the total fair value of the Company’s derivative liabilities recorded in other accrued liabilities on the Consolidated Balance Sheets was $0.1 million and $9.6 million, respectively.

During the year ended December 31, 2012, the Company recognized a gain of $7.2 million in accumulated other comprehensive income for the effective portion of its derivative instruments and reclassified a loss of $7.5 million from other comprehensive income to operating expense in the Consolidated Statements of Operations. During the year ended December 31, 2011, the Company recognized a loss of $7.9 million in accumulated other comprehensive income for the effective portion of its derivative instruments and reclassified a gain of $0.7 million from other comprehensive income to operating expense in the Consolidated Statements of Operations. During the year ended December 31, 2010, the Company recognized a loss of $3.0 million in accumulated other comprehensive income for the effective portion of its derivative instruments and reclassified a loss of $2.1 million from other comprehensive income to operating expense in the Consolidated Statements of Operations.

The ineffective portion of the Company's derivative instruments recognized in its Consolidated Statements of Operations was not material during the years ended December 31, 2012, 2011, and 2010.

Non-Designated Derivatives

The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement 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 income, net in the 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 between two months.

The Company recognized a net gain of $1.0 million, a gain of $1.5 million, and a loss of $0.3 million on non-designated derivative instruments within other (expense) income, net, in its Consolidated Statements of Operations during the years ended December 31, 2012, 2011, and 2010, respectively.

During the years ended December 31, 2012, 2011, and 2010, the Company added $54.1 million, $28.4 million, $116.5 million of purchased intangible assets as a result of acquisitions completed during 2012, 2011, and 2010, respectively. Refer to Note 3, Business Combinations, for further details.

During the year ended December 31, 2012, $6.8 million of acquired IPR&D accounted for as indefinite lived assets reached technological feasibility and were reclassified as amortizable finite-lived assets. Amortization of purchased intangible assets included in operating expenses and cost of product revenues totaled $32.3 million, $27.1 million, and $8.6 million for the years ended December 31, 2012, 2011, and 2010, respectively.

In connection with the restructuring plan in 2012 discussed in Note 9, Restructuring and Other Charges, the Company assessed the impairment and remaining useful life of certain intangible assets and determined intangible assets of $5.4 million were impaired and written-down to their fair value of zero and other intangible assets of $10.7 million will no longer be utilized. As a result, the Company recorded $16.1 million in charges related to these items during the year ended December 31, 2012, which are included in cost of revenues in the Consolidated Statements of Operations and recorded in the Company's SSD segment.

As of December 31, 2012, the estimated future amortization expense of purchased intangible assets with finite lives is as follows (in millions):

In 2011, the Company recorded a $13.5 million asset impairment charge in restructuring and other charges in the Consolidated Statement of Operations related to an abandoned in-process internal use software project.

Licensed Software

On July 3, 2012, the Company entered into an agreement with Riverbed Technology, Inc. ("Riverbed") to license Riverbed's Application Delivery Controller (“ADC”) software in exchange for the aggregate consideration of $88.0 million, which consist of the following: (1) cash consideration of $75.0 million ($65.0 million paid in the third quarter of 2012 and the remaining $10.0 million payable in the third quarter of 2013); (2) technology integration services with a fair value of $12.6 million; (3) technology partnership in wide area network optimization solutions; and (4) transaction costs of $0.4 million. Contingent consideration of up to $10.0 million has not been recorded but may also be payable to Riverbed if certain third-party approvals of the underlying technology integration services are not obtained.
The aggregate consideration of $88.0 million was allocated to the acquired ADC software of $84.4 million, associated prepaid maintenance and support of $1.0 million, and remaining amounts expected to be received through performance of services. The licensed software acquired was reported within other long-term assets on the Consolidated Balance Sheets. It will be amortized over its useful life of 6 years beginning in the period in which the product is available for general release to customers, estimated to be in 2013. The amortization expense will be recognized in cost of product revenues.
The technology integration services require the Company to develop certain technology, cross-license of associated software, and to provide support over seven years. The fair value of technology integration services, less estimated amounts to be reimbursed is reported within deferred revenue on the Consolidated Balance Sheets. Amounts are deferred until the underlying technology has been delivered. In the event third-party approval is not obtained within a reasonable time frame, up to $20.0 million becomes payable to Riverbed. This amount is held in escrow and reported within restricted cash and investments on the Consolidated Balance Sheets.
Warranties

The Company accrues for warranty costs as part of its cost of sales based on associated material costs, labor costs for customer support, and overhead at the time revenue is recognized. This provision is reported as accrued warranty within current liabilities on the Consolidated Balance Sheets. Changes in the Company’s warranty reserve were as follows (in millions):

Restructuring and Other Charges
Restructuring and Other Charges [Text Block]
Restructuring and Other 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 and other charges in the Consolidated Statements of Operations, as applicable. Any changes in the estimates of executing the approved plans will be reflected in the Company's results of operations. Restructuring liabilities are reported within other accrued liabilities and other long-term liabilities in the 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 desired 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 year ended December 31, 2012, the Company recorded $40.4 million in charges for workforce reductions, facility consolidations or closures, and other charges related to the 2012 Restructuring Plan. In connection with its restructuring activities, the Company also recorded certain inventory and intangible asset impairment charges and contract termination charges totaling $52.9 million to cost of revenues.

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 December 31, 2012 and 2011. Facilities-related charges are expected to be completed by March 2018.

During 2009, the Company implemented a restructuring plan (the "2009 Restructuring Plan") in an effort to better align its business operations with the market and macroeconomic conditions. The 2009 Restructuring Plan included restructuring of certain business functions that resulted in reductions of workforce and facilities. The Company recorded the majority of the restructuring charges associated with this plan during the years ended December 31, 2010 and 2009.

Long-Term Debt and Financing

Long-Term Debt

In March 2011, the Company issued $300.0 million aggregate principal amount of 3.10% senior notes due 2016 ("2016 Notes"), $300.0 million aggregate principal amount of 4.60% senior notes due 2021 ("2021 Notes"), and $400.0 million aggregate principal amount of 5.95% senior notes due 2041 ("2041 Notes" and, together with the 2016 Notes and the 2021 Notes, the "Notes"). Interest on the Notes is payable in cash semiannually. The Company may redeem the Notes, at any time in whole or from time to time in part, subject to a make-whole premium, and, in the event of a change in control, the holders of the Notes may require the Company to repurchase for cash all or part of the Notes at a purchase price equal to 101% of the aggregate principle amount, plus accrued and unpaid interest, if any. The indenture that governs the Notes also contains various covenants, including limitations on the Company's ability to incur liens or enter into sale-leaseback transactions over certain dollar thresholds. As of December 31, 2012, the Company was in compliance with all of its debt covenants.

At December 31, 2012 and December 31, 2011, the estimated fair value of the Notes included in long-term debt was approximately $1,090.7 million and $1,069.8 million, respectively, based on quoted market prices (Level 1).
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 $677.8 million, $738.2 million and $637.5 million during the years ended December 31, 2012, 2011, and 2010, respectively. The Company received cash proceeds from the financing provider of $679.8 million, $686.5 million, and $595.7 million during the years ended December 31, 2012, 2011, and 2010, respectively. As of December 31, 2012 and December 31, 2011, the amounts owed by the financing provider were $147.6 million and $162.9 million, respectively, and were recorded in accounts receivable on the Company’s Consolidated Balance Sheets.

The portion of the receivable 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 Consolidated Balance Sheets. As of December 31, 2012 and December 31, 2011, the estimated cash received from the financing provider not recognized as revenue from distributors was $30.7 million and $33.3 million, respectively.

Stock Repurchase Activities

In June 2012, the Company’s Board of Directors (the “Board”) approved a stock repurchase program (the "2012 Stock Repurchase Program"), which authorized the Company to repurchase up to $1.0 billion of its common stock. The 2012 Stock Repurchase Program was in addition to the stock repurchase program approved by the Board in February 2010 (the "2010 Stock Repurchase Program"), which authorized the Company to repurchase up to $1.0 billion of its common stock. The 2010 Stock Repurchase Program was in addition to the stock repurchase program approved by the Board in March 2008, which also enabled the Company to repurchase up to $1.0 billion of its common stock. As of December 31, 2012, there is $568.2 million of authorized funds remaining under the Company's Stock Repurchase Programs.

In addition to repurchases under the Company’s Stock Repurchase Programs, there were also repurchases of common stock from the Company's employees in connection with net issuance of shares to satisfy minimum tax withholding obligations for the vesting of certain stock awards.

As of December 31, 2012, a total of approximately 125.1 million shares of common stock were reserved for future issuance upon exercise of stock options and vesting of RSAs, RSUs, and PSAs, and for the future grant of share-based compensation awards under the Company's equity incentive plans and the 2008 Purchase Plan.

The 2006 Plan was adopted and approved by the Company’s stockholders in May 2006 and had an initial authorized share reserve of 64.5 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. In addition, the Company’s stockholders’ approved amendments to the 2006 Plan that increased the number of shares reserved for issuance under the 2006 Plan, thereby increasing the authorized share reserve by 30.0 million shares in both May 2010 and 2011, and 25.0 million shares in May 2012. As of December 31, 2012, the 2006 Plan had 54.2 million shares subject to currently outstanding equity awards and 54.3 million shares available for future issuance. Options granted under the 2006 Plan have a maximum term of seven years from the date of grant, and generally vest and become exercisable over a four-year period. Subject to the terms of change of control severance agreements, and except for a limited number of shares allowed under the 2006 Plan, RSUs or PSAs that vest solely based on continuing employment or provision of services will vest in full no earlier than three years from the grant date, or in the event vesting is based on factors other than continued future provision of services, such awards will vest in full no earlier than one year from the grant date.

During 2010 through 2012, the Company completed the acquisitions of Ankeena, Altor, Mykonos, and Contrail and assumed their respective plans: Ankeena Networks, Inc. 2008 Stock Plan; Altor Networks, Inc. 2007 Stock Plan and the 2009 Israeli Equity Incentive Sub Plan; Mykonos Software, Inc. 2010 Stock Plan, and Contrail Systems Inc. 2012 Stock Plan. In connection with these plans, the Company assumed stock options, RSA, and RSU awards and exchanged the assumed awards for Juniper Networks' stock options, RSAs, and RSUs. No new stock options, RSAs, and RSUs can be granted under these plans. The Company registered an aggregate of 1.3 million shares of its common stock, between 2010 and 2012, for stock awards previously granted under the assumed plans of the acquired companies and assumed 6.8 million shares of stock options, RSA, and RSU awards in connection with the acquisition of Contrail. As of December 31, 2012, stock options, RSAs, and RSUs representing approximately 7.2 million shares of common stock were outstanding under all awards assumed through the Company's acquisitions.

The Company adopted the 2008 Purchase Plan, in May 2008. The Board had an initial authorized share reserve of 12.0 million shares of the Company's common stock for issuance under this plan. In addition, the Company’s stockholders’ approved amendments to the 2008 Plan that increased the number of shares reserved for issuance under the 2008 Plan, thereby increasing the authorized share reserve by 7.0 million in May 2012. 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.

Stock Option Activities

Since 2006, the Company has granted stock option awards that have a maximum contractual life of seven years from the date of grant. Prior to 2006, stock option awards generally had a ten-year contractual life from the date of grant.

401(k) Plan

The Company maintains a savings and retirement plan qualified under Section 401(k) of the Internal Revenue Code of 1986, as amended (the "IRC"). Employees meeting the eligibility requirements, as defined under the IRC, may contribute up to the statutory limits each year. The Company has matched employee contributions since January 1, 2001, currently matching 30% of all eligible employee contributions. All matching contributions vest immediately. The Company’s matching contributions to the plan totaled $20.2 million, $16.3 million, and $13.2 million during the years ended December 31, 2012, 2011, and 2010, respectively.

Deferred Compensation Plan

The Company’s non-qualified deferred compensation (“NQDC”) plan is an unfunded and unsecured deferred compensation arrangement. Under the NQDC plan, officers and other senior employees may elect to defer a portion of their compensation and contribute such amounts to one or more investment funds. The NQDC plan assets are included within short-term investments, and offsetting obligations are included within accrued compensation in the Consolidated Balance Sheets. The investments are considered trading securities and are reported at fair value. The realized and unrealized holding gains and losses related to these investments are recorded in other expense, net, and the offsetting compensation expense is recorded as operating expenses in the Consolidated Statements of Operations. The deferred compensation liability under the NQDC plan was approximately $12.6 million and $9.3 million as of December 31, 2012 and December 31, 2011, respectively. For additional information regarding the Company's NQDC, see Note 4, Cash Equivalents and Investments.
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 fiscal 2012, the Company reorganized its operations into two reportable segments principally by product families: PSD and SSD. As a result of the change, product families and services were organized within the two divisions based on homogeneity of products and technology.

To provide improved visibility and comparability, the Company reclassified segment operating results for 2011 and 2010 to conform with the 2012 organizational realignments.

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"), branch, and customer premise equipment level. The Company's PSD segment consists of routing, switching, and security/other products and services. Routing includes products and services from the ACX, E, M, MX, PTX and T Series. Switching primarily consists of products and services for EX Series and wireless local area network solutions, as well as QFabric™. Security/other include products and services from the branch SRX, branch firewall, and J Series, as well as the network application platform, Junos® Space.

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/other and routing products and services. Security/other includes High-End SRX services and vGW Virtual Gateways, High-End Firewall, virtual private network systems and appliances, secure socket layer virtual private network appliances, intrusion detection and prevention appliances, wide area network optimization platforms, and Junos Pulse. Routing primarily consists of Routing Services Software and Mobile Applications (such as MobileNextTM).

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 includes: 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 years ended December 31, 2012 and 2010, Verizon accounted for 10.3% and 10.4% of net revenues, respectively, and was reported in the Company's PSD and SSD segments. During the year ended December 31, 2011, no single customer accounted for 10% or more 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 December 31, 2012 and December 31, 2011, were attributable to U.S. operations. For the years ended December 31, 2012 and December 31, 2011, gross property and equipment held in the U.S., as a percentage of total property and equipment, was approximately 83% and 80%, 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.

As of December 31, 2012, and 2011, the Company had a valuation allowance on its U.S. domestic deferred tax assets of approximately $141.0 million and $145.2 million, respectively. The balance at December 31, 2012 consisted of approximately $94.8 million and $9.7 million against the Company's California and Massachusetts deferred tax assets, respectively, which the Company believes are not more likely than not to be utilized in future years. The remaining deferred tax assets on which the Company recorded a valuation allowance are approximately $36.5 million related to losses that are capital in nature and may carry forward to offset future capital gains. The valuation allowance decreased by $4.2 million and increased $23.0 million in the years ended December 31, 2012 and 2011, respectively. The 2012 decrease relates to the utilization of losses that are capital in nature. Approximately $13.7 million and $9.7 million of the 2011 increase were due to changes in income apportioned to California and Massachusetts, respectively. The income apportioned to Massachusetts and California impacts the future taxable income within these states for the years in which the deferred tax assets are expected to be realized or settled.
 
As of December 31, 2012, the Company had federal and California net operating loss carry-forwards of approximately $24.9 million and $39.6 million, respectively. The Company also had California tax credit carry-forwards of approximately $184.0 million. Approximately $14.8 million of the benefit from the California tax credit carry-forwards will be credited to additional paid-in capital when realized on the Company's income tax returns. Unused net operating loss carry-forwards will expire at various dates beginning in the year 2013. The California tax credit carry-forwards will carry forward indefinitely.
 
The Company provides U.S. income taxes on the earnings of foreign subsidiaries unless the subsidiaries' earnings are considered indefinitely reinvested outside of the United States. The Company has made no provision for U.S. income taxes on approximately $1,609.1 million of cumulative undistributed earnings of certain foreign subsidiaries through December 31, 2012, because it is the Company's intention to permanently reinvest such earnings. If such earnings were distributed, the Company would accrue additional income tax expense of approximately $483.4 million. These earnings are considered indefinitely invested in operations outside of the U.S., as we intend to utilize these amounts to fund future expansion of our international operations.

As of December 31, 2012, 2011, and 2010 the total amount of gross unrecognized tax benefits was $136.1 million, $132.2 million, and $116.4 million, respectively. As of December 31, 2012, approximately $122.4 million of the $136.1 million gross unrecognized tax benefits, if recognized, would affect the effective tax rate.
 
A reconciliation of the beginning and ending amount of the Company's total gross unrecognized tax benefits was as follows (in millions):

As of December 31, 2012, 2011, and 2010 the Company had accrued interest and penalties related to unrecognized tax benefits of $16.7 million, $17.3 million, and $18.9 million, respectively, within other long-term liabilities in the Consolidated Balance Sheets. In accordance with the Company's accounting policy, accrued interest and penalties related to unrecognized tax benefits are recognized as a component of tax expense in the consolidated statements of operations. The Company recognized a benefit for net interest and penalties of $0.6 million and $1.6 million, and an expense of $4.6 million in its Consolidated Statements of Operations during the years ended December 31, 2012, 2011, and 2010, respectively.
 
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 $0 to $42.0 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.

During the fourth quarter of 2011, the Company resolved an audit by a state tax authority for the years from 2002 through 2004. As a result of the settlement, the Company recorded a tax benefit of approximately $7.0 million including interest and penalties.
 
During 2010, the Company recognized approximately $73.4 million of tax benefits related to share-based compensation, which the Company had previously recorded as unrecognized tax benefits in 2009. On March 22, 2010, the Court overturned its May 27, 2009 decision in Xilinx v. Commissioner and affirmed the original U.S. Tax Court decision, which held in favor of the taxpayer. While Juniper Networks was not a named party to the case, the Court's decision eliminates the uncertainty regarding the benefit of the tax position taken by the Company in certain years prior to fiscal 2004 relative to the allocable transfer price of share-based compensation related to the Company's intangible development costs. The Court's decision affirms that the value of share-based compensation related to share-based compensation grants made prior to 2004 is not required to be included in cost sharing agreements between related parties. In light of the Court's decision, the Company has determined that the tax benefit recognized under its prior tax position is more likely than not to be sustained.

The Company conducts business globally and, as a result, Juniper Networks or one or more of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Ireland, Hong Kong, U.K., France, Germany, The Netherlands, Japan, China, Australia, India, and the U.S. With few exceptions, the Company is no longer subject to U.S. federal, state and local, and non-U.S. income tax examinations for years before 2004, although carry-forward attributes that were generated prior to 2004 may still be adjusted upon examination by the Internal Revenue Service ("IRS") if the attributes either have been or will be used in a future period.
 
The Company is currently under examination by the IRS for the 2004 through 2009 tax years. The Company is also subject to two separate ongoing examinations by the India tax authorities for the 2004 tax year and 2004 through 2008 tax years, respectively. Additionally, the Company has not reached a final resolution with the IRS on an adjustment it proposed for the 1999 and 2000 tax years. The Company is not aware of any other examination by taxing authorities in any other major jurisdictions in which it files income tax returns as of December 31, 2012.
 
In 2011, as part of the 2005 and 2006 IRS audit, the Company received a proposed adjustment related to its intercompany R&D cost sharing arrangement for the license of intangibles acquired in 2005. In 2009, as part of the 2004 IRS audit, the Company received a similar proposed adjustment related to the license of intangibles acquired in 2004.

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 the India tax authorities may issue an initial assessment that is substantially higher than this amount. As a result, 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 the matters referenced above. 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.

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, employee stock purchase plan 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 32.3 million, 17.4 million, and 14.0 million shares were outstanding but were not included in the computation of diluted earnings per share for the years ended December 31, 2012, 2011, and 2010, respectively.

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 $266.1 million as of December 31, 2012. Rent expense for 2012, 2011, and 2010 was approximately $63.2 million, $65.7 million, and $55.9 million, respectively.

Purchase Commitments

In order to reduce manufacturing lead times and ensure adequate component supply, contract manufacturers utilized by the Company place NCNR orders for components based on the Company’s build forecasts. As of December 31, 2012, there were NCNR component orders placed by the contract manufacturers with a value of $158.6 million. The contract manufacturers use the components to build products based on the Company’s forecasts and customer purchase orders received by the Company. Generally, the Company does not own the components and title to the products transfers from the contract manufacturers to the Company and immediately to the Company’s customers upon delivery at a designated shipment location. The Company establishes a liability for NCNR commitments for carrying charges, quantities in excess of our demand forecasts, or obsolete materials charges for components purchased by contract manufacturers to meet the Company’s forecast or customer orders. As of December 31, 2012, the Company had accrued $27.7 million based on its estimate of such charges.

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

As of December 31, 2012, 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 December 31, 2012, other contractual obligations primarily consisted of $124.2 million in indemnity-related and service related escrows, required by certain asset purchases and acquisitions completed in 2005, 2010, 2011, and 2012, and $55.1 million in campus build-out obligations.
Tax Liabilities

In addition to the table, as of December 31, 2012, the Company had $112.4 million included in long-term liabilities in the 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 December 31, 2012 and December 31, 2011, the Company had $12.6 million and $19.9 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 2004 through 2009 tax years. Additionally, the Company has not reached a final resolution with the IRS on an adjustment it proposed for the 1999 and 2000 tax years.

In May 2011, as part of the 2005 and 2006 IRS audit, the Company received a proposed adjustment related to its intercompany R&D cost sharing arrangement for the license of intangibles acquired in 2005. In 2009, as part of the 2004 IRS audit, the Company received a similar proposed adjustment related to the license of intangibles acquired in 2004. The combined estimated incremental tax liabilities related to these proposed adjustments would be approximately $900.0 million, excluding interest and penalties. The Company has filed protests to the proposed deficiencies which are under review by the Appeals Division of the IRS.

The Company is pursuing all available administrative procedures relative to the IRS audit matters referenced above. 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.

_______________________________
(1)
During the third quarter of 2012, the Company recorded net out of period adjustments reducing income before income taxes and noncontrolling interest by $8.2 million. These net adjustments resulted in increased research and development expense by $18.6 million related to prototype development costs, partially offset by increased net revenues of $6.2 million related to the reversal of certain revenue obligations and reduced cost of revenues by $4.2 million related to inventory purchases. The Company assessed the materiality of these adjustments, using relevant quantitative and qualitative factors, and determined that these adjustments, both individually and in the aggregate, were not material to any previously reported period.
(2)
In the third quarter of 2012, the Company implemented the 2012 Restructuring Plan for workforce reductions, facility consolidations or closures, and supply chain and procurement efficiencies and recorded restructuring charges of $29.5 million. In connection with its restructuring activities, the Company also recorded certain inventory and intangible asset impairment charges totaling $52.4 million to cost of revenues. In the fourth quarter of 2012, the Company continued to implement restructuring activities under the 2012 Restructuring Plan.
(3)
Acquisition-related and other charges comprised of direct and indirect costs such as financial advisory, legal, and due diligence, as well as integration costs related to the acquisitions completed in 2011 and 2012.
(4)  
Net income per share attributable to Juniper Network stockholders is computed independently. Therefore, the sum of the quarterly net income per share may not equal the total computed for the fiscal year or any cumulative interim period.

Significant Accounting Policies (Policies)
Use of Estimates [Policy Text Block] 
Use of Estimates
 
The preparation of the financial statements and related disclosures in conformity with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances, to determine the carrying values of assets and liabilities that are not readily apparent from other sources. To the extent there are material differences between the Company's estimates and the actual results, the Company's future consolidated results of operation may be affected.
Fair Value [Policy Text Block] 
Fair Value

Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it transacts, and considers assumptions that market participants would use when pricing the asset or liability. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

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

Level 2 – Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. These inputs are valued using market based approaches.

Level 3 – Inputs are unobservable inputs based on the Company’s assumptions. These inputs, if any, are valued using internal financial models.
Cash and Cash Equivalents [Policy Text Block] 
Cash and Cash Equivalents

All highly liquid investments purchased with a remaining maturity of three months or less are classified as cash and cash equivalents. Cash and cash equivalents consist of cash on hand, demand deposits with banks, highly liquid investments in money market funds, commercial paper, government securities, certificates of deposit, and corporate debt securities, which are readily convertible into cash.
Investments in Available-for-Sale and Trading Securities [Policy Text Block] 
Investments in Available-for-Sale and Trading Securities

The Company's investments in publicly-traded debt and equity securities are classified as available-for-sale. Available-for-sale investments are initially recorded at cost and periodically adjusted to fair value in the consolidated balance sheets. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss). Realized gains and losses are determined based on the specific identification method and are reported in the consolidated statements of operations.

The Company recognizes an impairment charge for available-for-sale investments when a decline in the fair value of its investments below the cost basis is determined to be other than temporary. The Company considers various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value has been less than the Company's cost basis, the investment's financial condition, and near-term prospects of the investee. If the Company determines that the decline in an investment's fair value is other than temporary, the difference is recognized as an impairment loss in its Consolidated Statements of Operations.

The Company's non-qualified compensation plan, which invests in mutual funds are classified as trading securities and reported at fair value in the Consolidated Balance Sheets. The realized and unrealized holding gains and losses are reported in the Consolidated Statements of Operations.
Privately-Held Investments [Policy Text Block] 
Privately-Held Investments
 
The Company has investments in privately-held companies. These investments are included in other long-term assets in the Consolidated Balance Sheets and are carried at cost, adjusted for any impairment, as the Company does not have a controlling interest and does not have the ability to exercise significant influence over these companies. These investments are inherently high risk as the market for technologies or products manufactured by these companies are usually early stage at the time of the investment by the Company and such markets may never be significant. The Company measures the fair value of privately-held investments using an analysis of the financial conditions and near term prospects of the investees, including recent financing activities and their capital structure. Realized gains and losses, if any, are reported in the Consolidated Statements of Operations.
Derivatives [Policy Text Block] 
Derivatives
 
The Company uses derivatives to partially offset its market exposure to fluctuations in certain foreign currencies. The Company does not enter into derivatives for speculative or trading purposes.
 
The Company uses foreign currency forward contracts to mitigate variability in gains and losses generated from the re-measurement of certain monetary assets and liabilities denominated in non-functional currencies. These derivatives are carried at fair value with changes recorded in other (expense) income, net. 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. These foreign exchange forward contracts have maturities of one year or less.
The Company also uses foreign currency forward or option contracts to hedge certain forecasted foreign currency transactions relating to operating expenses. These derivatives are designated as cash flow hedges and have maturities of less than one year. These derivatives are carried at fair value and the effective portion of the derivative's gain or loss is initially reported as a component of accumulated other comprehensive income (loss), and upon occurrence of the forecasted transaction, is subsequently reclassified into the operating expense line item to which the hedged transaction relates. The Company records any ineffectiveness of the hedging instruments, which was immaterial during 2012, 2011, and 2010, in other (expense) income, net, on its Consolidated Statements of Operations. Cash flows from such hedges are classified as operating activities.

Concentrations [Policy Text Block] 
Concentrations
 
Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments, and accounts receivable. The Company invests only in high-quality credit instruments and maintains its cash, cash equivalents and available-for-sale investments in fixed income securities with several high-quality institutions. Deposits held with banks, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand and, therefore, bear minimal risk.
 
Generally, credit risk with respect to accounts receivable is diversified due to the number of entities comprising the Company's customer base and their dispersion across different geographic locations throughout the world. The Company performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. The Company maintains reserves for potential bad debt and historically such losses have been within management's expectations. During the years ended December 31, 2012 and 2010, Verizon Communications, Inc. ("Verizon") accounted for 10.3% and 10.4% of net revenues, respectively. During the year ended December 31, 2011, no single customer accounted for 10% or more of net revenues.
 
The Company relies on sole suppliers for certain of its components such as ASICs and custom sheet metal. Additionally, the Company relies primarily on a limited number of significant independent contract manufacturers for the production of all of its products. The inability of any supplier or manufacturer to fulfill supply requirements of the Company could negatively impact future operating results.
Inventory [Policy Text Block] 
Inventory
Inventory consists primarily of component parts to be used in the manufacturing process and is stated at the lower of average cost or market. A provision is recorded when inventory is determined to be in excess of anticipated demand or obsolete, to adjust inventory to its estimated realizable value.
Property and Equipment [Policy Text Block] 
Property and Equipment
 
Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets of one and half years to five years for computers, equipment and software, five years for furniture and fixtures, seven to forty years for building and building improvements, and ten to forty years for land improvements. Leasehold improvements are amortized using the straight-line method over lease term, for a maximum of ten years. Construction in progress is related to the construction or development of property and equipment that have not yet been placed in service for their intended use. Depreciation for equipment commences once it is placed in service and depreciation for buildings and leasehold improvements commences once they are ready for their intended use.
 
Goodwill and Other Long-Lived Assets [Policy Text Block] 
Goodwill and Other Long-Lived Assets
 
Goodwill represents the future economic benefits arising from other assets acquired in a business combination or an acquisition that are not individually identified and separately recorded. The excess of the purchase price over the estimated fair value of net assets of businesses acquired in a business combination is recognized as goodwill. Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually during the fourth quarter. Such goodwill and other intangible assets may also be tested for impairment between annual tests in the presence of impairment indicators such as, but not limited to: (a) a significant adverse change in legal factors or in the business climate; (b) a substantial decline in our market capitalization, (c) an adverse action or assessment by a regulator; (d) unanticipated competition; (e) loss of key personnel; (f) a more likely-than-not expectation of sale or disposal of a reporting unit or a significant portion thereof; (g) a realignment of our resources or restructuring of our existing businesses in response to changes to industry and market conditions; (h) testing for recoverability of a significant asset group within a reporting unit; or (i) higher discount rate used in the impairment analysis as impacted by an increase in interest rates.

The Company performs its annual goodwill impairment analysis at its reporting unit level, which is one level below its operating segment level during the fourth quarter of each year. The fair value of the Company's reporting units is determined using both the income and market valuation approaches. Under the income approach, the fair value of the reporting unit is based on the present value of estimated future cash flows that the reporting unit is expected to generate over its remaining life. Under the market approach, the value of the reporting unit is based on an analysis that compares the value of the reporting unit to values of publicly traded companies in similar lines of business. In the application of the income and market valuation approaches, the Company is required to make estimates of future operating trends and judgments on discount rates and other variables. Actual future results related to assumed variables could differ from these estimates.

Long-lived assets, such as property, plant, and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Such events or circumstances include, but are not limited to, a significant decrease in the fair value of the underlying business, a significant decrease in the benefits realized from an acquired business, difficulties or delays in integrating the business or a significant change in the operations of an acquired business. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group, to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. An impairment charge is recognized by the amount by which the carrying amount of the asset, or asset group, exceeds its fair value.

The Company amortizes intangible assets with estimable useful lives on a straight-line basis over their useful lives.
Revenue Recognition [Policy Text Block] 
Revenue Recognition
 
Revenue is recognized when all of the following criteria have been met:

•
Persuasive evidence of an arrangement exists.  The Company generally relies upon sales contracts or agreements, and customer purchase orders to determine the existence of an arrangement.

•
Delivery has occurred.  The Company uses shipping terms and related documents, or written evidence of customer acceptance, when applicable, to verify delivery or performance.

•
Sales price is fixed or determinable.  The Company assesses whether the sales price is fixed or determinable based on the payment terms and whether the sales price is subject to refund or adjustment.

•
Collectability is reasonably assured.  The Company assesses collectability based on creditworthiness of customers as determined by our credit checks and their payment histories. The Company records accounts receivable net of allowance for doubtful accounts, estimated customer returns, and pricing credits.
 
When sales arrangements contain multiple elements and software and non-software components that function together to deliver the tangible products' essential functionality, the Company allocates revenue to each element based on a selling price hierarchy. The selling price for a deliverable is based on either vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) if VSOE is not available, or estimated selling price (“ESP”) if neither VSOE nor TPE is available. The Company then recognizes revenue on each deliverable in accordance with its policies for product and service revenue recognition. VSOE of selling price is based on the price charged when the element is sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices fall within a reasonable range based on historical discounting trends for specific products and services. TPE of selling price is established by evaluating largely interchangeable competitor products or services in stand-alone sales to similarly situated customers. However, as the Company's products contain a significant element of proprietary technology and its solutions offer substantially different features and functionality, the comparable pricing of third-party products with similar functionality typically cannot be obtained. ESP is established considering multiple factors including, but not limited to pricing practices in different geographies and through different sales channels, gross margin objectives, internal costs, competitor pricing strategies, and industry technology lifecycles.

In multiple element arrangements where software deliverables are included, revenue is allocated to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. If the arrangement contains more than one software deliverable, the arrangement consideration allocated to the software deliverables as a group is then allocated to each software deliverable using the residual method when VSOE of fair value of the undelivered items exists. Under the residual method, the amount of revenue allocated to delivered elements equals the total arrangement consideration less the aggregate fair value of any undelivered elements. If VSOE of one or more undelivered items does not exist, revenue from the entire arrangement is deferred and recognized at the earlier of: (i) delivery of those elements or (ii) when fair value can be established unless maintenance is the only undelivered element, in which case, the entire arrangement fee is recognized ratably over the contractual support period.

The Company limits the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services or subject to customer-specific return or refund privileges.

The Company records reductions to revenue for estimated product returns and pricing adjustments, such as rebates and price protection, in the same period that the related revenue is recorded. The amount of these reductions is based on historical sales returns and price protection credits, specific criteria outlined in rebate agreements, and other factors known at the time. A portion of the Company's sales is made through distributors under agreements allowing for pricing credits or rights of return. Product revenue on sales made through these distributors is recognized upon sell-through as reported by the distributors to the Company. Deferred revenue on shipments to distributors reflects the effects of distributor pricing credits and the amount of gross margin expected to be realized upon sell-through. Deferred revenue is recorded net of the related product costs of revenue.
 
Service revenues include revenue from maintenance, training, and professional services. Maintenance is offered under renewable contracts. Revenue from maintenance service contracts is deferred and recognized ratably over the contractual support period, which is generally one to three years. Revenue from training and professional services is recognized as services are completed or ratably over the contractual period, which is generally one year or less.
 
The Company sells certain interests in accounts receivable on a non-recourse basis as part of customer financing arrangements primarily with one major financing company. Cash received under this arrangement in advance of revenue recognition is recorded as a secured borrowing within other current liabilities.
Allowance For Doubtful Accounts [Policy Text Block] 
Allowance for Doubtful Accounts
 
The allowance for doubtful accounts is based on the Company's assessment of the collectability of customer accounts. The Company regularly reviews its receivables that remain outstanding past their applicable payment terms and establishes an allowance by considering factors such as historical experience, credit quality, age of the accounts receivable balances, and current economic conditions that may affect a customer's ability to pay.
Warranty Reserves [Policy Text Block] 
Warranty Reserves
 
The Company generally offers a one-year warranty on all of its hardware products and a 90-day warranty on the media that contains the software embedded in the products. Warranty costs are recognized as part of the Company's cost of sales based on associated material costs, labor costs, and overhead at the time revenue is recognized. Material costs are estimated primarily based upon the historical costs to repair or replace product returns within the warranty period. Labor and overhead costs are estimated primarily based upon historical trends in the cost to support customer cases within the warranty period.
Contract Manufacturer Liabilities [Policy Text Block] 
Contract Manufacturer Liabilities
 
The Company establishes a liability for non-cancelable, non-returnable ("NCNR") purchase commitments with its contract manufacturers for carrying charges, quantities in excess of its demand forecasts, or obsolete material charges for components purchased by the contract manufacturers to meet the Company’s demand forecast or customer orders. The demand forecasts are based upon historical trends and analysis from the Company's sales and marketing organizations, adjusted for overall market conditions.
Research and Development [Policy Text Block] 
Research and Development
 
Costs to research, design, and develop the Company's products are expensed as incurred. Software development costs are capitalized beginning when a product's technological feasibility has been established and ending when a product is available for general release to customers. Generally, the Company's products are released soon after technological feasibility has been established. As a result, costs incurred between achieving technological feasibility and product general availability have not been significant.
Advertising [Policy Text Block] 
Advertising
 
Advertising costs are charged to sales and marketing expense as incurred. Advertising expense was $20.0 million, $17.2 million, and $17.1 million, for 2012, 2011, and 2010, respectively.
Foreign Currency Translations [Policy Text Block] 
Foreign Currency Translations
 
Assets and liabilities of foreign operations with non-U.S. Dollar functional currency are translated to U.S. Dollars using exchange rates in effect at the end of the period. Revenue and expenses are translated to U.S. Dollars using average exchange rates for the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets in the stockholders’ equity section as a component of accumulated other comprehensive income (loss).
Loss Contingencies [Policy Text Block] 
Loss Contingencies
 
The Company is subject to the possibility of various loss contingencies arising in the ordinary course of business. Management considers the likelihood of loss related to an asset, or the incurrence of a liability, as well as its ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted and whether new accruals are required.
Share-based Compensation [Policy Text Block] 
Share-Based Compensation

The Company utilizes the Black-Scholes-Merton (“BSM”) option-pricing model to estimate the fair value of its stock options and ESPP shares. The Company determines the fair value of its restricted stock units ("RSUs"), restricted stock awards ("RSAs"), and performance share awards ("PSAs") based on the closing market price of the Company’s common stock on the date of grant. Share-based compensation expense is based on the fair value the underlying awards and amortized on a straight-line basis, net of estimated forfeitures. With respect to PSAs, that generally vest after three years, for the portion of the award attributable to each performance year, the Company recognizes PSA expense on a straight-line basis over the remaining vesting period starting in the period in which the annual performance targets are set for each such performance year.

The BSM model requires various highly subjective assumptions that represent management's best estimates of volatility, risk-free interest rate, expected life, and dividend yield. The expected volatility is based on the implied volatility of market-traded options on the Company's common stock, adjusted for other relevant factors including historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options. The expected life of a stock option award is based on historical experience.
Provision for Income Taxes [Policy Text Block] 
Provision for Income Taxes
 
Income tax expense is based on pretax financial accounting income. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized.
The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that the Company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.

Recent Accounting Pronouncements [Policy Text Block] 
Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2013-02, Topic 350 - Comprehensive Income ("ASU 2013-02"), which amends Topic 220 to improve the reporting of reclassifications out of accumulated other comprehensive income to the respective line items in net income. ASU 2013-02 is effective for reporting periods beginning after December 15, 2012. The Company intends to adopt this standard in the first quarter of 2013 and does not expect the adoption will have a material impact on its consolidated results of operations or financial condition.

In July 2012, the FASB issued ASU No. 2012-02, Topic 350 - Intangibles - Goodwill and Other ("ASU 2012-02"), which amends Topic 350 to allow an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value. An entity would not be required to determine the fair value of the indefinite-lived intangible unless the entity determines, based on the qualitative assessment, that it is more likely than not that its fair value is less than the carrying value. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 and early adoption is permitted. The Company intends to adopt this standard in the first quarter of 2013 and does not expect the adoption will have an impact on its consolidated results of operations or financial condition.

_______________________________
(1)
During the third quarter of 2012, the Company recorded net out of period adjustments reducing income before income taxes and noncontrolling interest by $8.2 million. These net adjustments resulted in increased research and development expense by $18.6 million related to prototype development costs, partially offset by increased net revenues of $6.2 million related to the reversal of certain revenue obligations and reduced cost of revenues by $4.2 million related to inventory purchases. The Company assessed the materiality of these adjustments, using relevant quantitative and qualitative factors, and determined that these adjustments, both individually and in the aggregate, were not material to any previously reported period.
(2)
In the third quarter of 2012, the Company implemented the 2012 Restructuring Plan for workforce reductions, facility consolidations or closures, and supply chain and procurement efficiencies and recorded restructuring charges of $29.5 million. In connection with its restructuring activities, the Company also recorded certain inventory and intangible asset impairment charges totaling $52.4 million to cost of revenues. In the fourth quarter of 2012, the Company continued to implement restructuring activities under the 2012 Restructuring Plan.
(3)
Acquisition-related and other charges comprised of direct and indirect costs such as financial advisory, legal, and due diligence, as well as integration costs related to the acquisitions completed in 2011 and 2012.
(4)  
Net income per share attributable to Juniper Network stockholders is computed independently. Therefore, the sum of the quarterly net income per share may not equal the total computed for the fiscal year or any cumulative interim period.
