Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Basis of Presentation

The unaudited Condensed Consolidated Financial Statements of Juniper Networks, Inc. (“Juniper Networks” or the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information as well as the instructions to Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of December 31, 2011, is derived from the audited consolidated financial statements for the year ended December 31, 2011. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three months ended March 31, 2012, are not necessarily indicative of the results that may be expected for the year ending December 31, 2012, or any future period. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Management's Discussion and Analysis of Financial Condition and Results of Operations,” “Risk Factors,” “Quantitative and Qualitative Disclosures About Market Risk,” and the Consolidated Financial Statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011.

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Condensed Financial Statements and accompanying notes. Actual results could differ materially from those estimates.

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"). In fiscal 2011, the Company was organized into two reportable segments, Infrastructure and Service Layer Technology ("SLT"). The Company has reclassified the segment data for the prior period 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.

As of March 31, 2012, the Company 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. NSN has assumed the activities of the joint venture. The Company is in the process of winding down this joint venture and the termination of this joint venture is not expected to have a material effect on the Company's financial position or results of operations.

Note 2. Summary of Significant Accounting Policies

Recent Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-08, Topic 350 - Intangibles - Goodwill and Other ("ASU 2011-08"), which amends Topic 350 and provides entities an option to perform a qualitative assessment to determine whether further impairment testing on goodwill is necessary. Specifically, an entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The Company adopted this standard in the first quarter of 2012. The Company’s adoption of the standard during the first quarter of 2012 did not impact its consolidated results of operations or financial condition.

In June 2011, the FASB issued ASU No. 2011-05, Topic 220 - Presentation of Comprehensive Income (“ASU 2011-05”), which requires companies to present net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements. In addition, in December 2011, the FASB issued Accounting Standards Update ("ASU") No. 2011-12, Topic 220 - Comprehensive Income ("ASU 2011-12"), which defers the requirement to present components of reclassifications of other comprehensive income on the face of the income statement. The Company adopted both standards in the first quarter of 2012. The Company’s adoption of the standard during the first quarter of 2012 did not impact its consolidated results of operations or financial condition.

In May 2011, the FASB issued ASU No. 2011-04, Topic 820 - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”), which amends the fair value measurement guidance and includes some enhanced disclosure requirements. The most significant change in disclosures is an expansion of the information required for Level 3 measurements based on unobservable inputs. The Company adopted this standard in the first quarter of 2012. The Company’s adoption of the standard during the first quarter of 2012 did not impact its consolidated results of operations or financial condition.

Note 3. Business Combinations

The Company's consolidated financial statements include the operating results of acquired businesses from the date of each acquisition. Pro forma results of operations for these acquisitions have not been presented as the financial impact to the Company's consolidated results of operations, both individually and in aggregate, is not material.

Q1'12 Acquisitions

In the three months ended March 31, 2012, the Company completed two acquisitions. The fair values of certain tangible assets and liabilities acquired, income based taxes, and residual goodwill are not yet finalized and subject to change. The Company expects to continue to obtain information to assist in determining the fair value of the net assets acquired at the acquisition date during the measurement period. Measurement period adjustments determined to be material will be applied retrospectively to the period of acquisition.

On February 13, 2012, the Company acquired 100% of the equity securities of Mykonos Software, Inc ("Mykonos") for $82.6 million in cash. The acquisition of Mykonos is intended to extend Juniper's security portfolio with an intrusion deception system capable of detecting an attacker before an attack is in process. In connection with this acquisition, the Company acquired net liabilities of $0.8 million, and recognized goodwill of $59.1 million, which was assigned to the SSD segment.

On March 8, 2012, the Company acquired a source code license and patent joint-ownership related to the service management layer of BitGravity, Inc ("BitGravity") Content Delivery Network ("CDN") technology for $13.0 million in cash. The transaction complements the Company's Media Flow Solution and content and media delivery strategy, to enables service providers, on-line media companies, and content delivery networks to deliver on-line content more cost-effectively while simultaneously improving the end-user experience. In connection with this acquisition, the Company acquired net assets of $0.1 million, and recognized goodwill of $0.5 million, which was assigned to the SSD segment.

The following table presents the preliminary purchase consideration allocations for these acquisitions, including cash and cash equivalents acquired (in millions):



	Q1'12 Acquisitions
	Mykonos			BitGravity		Total
Net tangible assets/(liabilities) acquired	$	(0.8	)	$	0.1	$	(0.7	)
Intangible assets acquired	24.3			12.4		36.7
Goodwill	59.1			0.5		59.6
Total	$	82.6		$	13.0	$	95.6

The Company recognized $1.1 million and $5.1 million of acquisition-related costs during the first quarter of 2012 and 2011, respectively. These acquisition related charges were expensed in the period incurred and reported in the Company's condensed consolidated statements of comprehensive income within cost of revenues and operating expenses.

The goodwill recognized is attributable primarily to expected synergies. None of the goodwill is deductible for U.S. federal income tax purposes for the acquisitions completed during the first quarter of 2012.

Intangible Assets Acquired

The following table presents details of the intangible assets acquired through the business combinations completed during the first quarter of 2012 (in millions, except years):

Notes to Condensed Consolidated Financial Statements (Continued)



	Q1'12 Acquisitions
	Mykonos			BitGravity
	Estimated Useful Life (In Years)	Amount		Estimated Useful Life (In Years)	Amount
Existing technology	6	$	19.3	3	$	12.4
Trade name and trademarks	7	1.0		—	—
In-process research and development	—	4.0		—	—
Total		$	24.3		$	12.4

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.

Note 4. Net Income per Share

The Company computed basic and diluted net income per share attributable to Juniper Networks common stockholders as follows (in millions, except per share amounts):



	Three Months Ended March 31,
	2012		2011
Numerator:
Net income attributable to Juniper Networks	$	16.3	$	129.8
Denominator:
Weighted-average shares used to compute basic net income per share	527.2		530.8
Dilutive effect of employee stock awards	6.5		18.0
Weighted-average shares used to compute diluted net income per share	533.7		548.8
Net income per share attributable to Juniper Networks common stockholders:
Basic	$	0.03	$	0.24
Diluted	$	0.03	$	0.24

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, vesting of restricted stock units ("RSUs"), and vesting of performance share awards ("PSAs").

The Company excludes both outstanding stock options with exercise prices that are greater than the average market price and RSUs 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 30.6 million and 5.8 million shares were outstanding but were not included in the computation of diluted net income per share for the three months ended March 31, 2012 and 2011, respectively.

(1)	Balance includes investments that were in an immaterial unrealized loss position as of December 31, 2011.

The Company had 89 and 135 investments in unrealized loss positions as of March 31, 2012, and December 31, 2011, respectively. The gross unrealized losses related to these investments were primarily due to changes in market interest rates. For the fixed income securities that have unrealized losses, the Company determined 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. The Company did not consider these investments to be other-than-temporarily impaired as of March 31, 2012, and December 31, 2011. 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.

Restricted Cash and Investments

The Company classifies cash and investments as restricted cash and investments on its condensed consolidated balance sheet 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 the Company's India and Israel employees, respectively; and (iii) the Directors and Officers ("D&O") indemnification trust. During the three months ended March 31, 2012, the Company distributed approximately $79.0 million of restricted cash, mainly related to the 2012 acquisitions.

In connection with the 2010 acquisition of Ankeena Networks, Inc. ("Ankeena"), the Company agreed to pay from escrow a total amount of $10.7 million, representing the cash value of unvested restricted shares of Ankeena common stock as of April 8, 2010, held by certain former Ankeena employees. Through March 31, 2012, the Company has released $10.6 million from escrow and expects to release the remaining $0.1 million from escrow over the next six months.

The following table summarizes the Company's cash and investments that are classified as restricted cash and investments in the condensed consolidated balance sheets (in millions):

The Company's policy is to recognize asset or liability transfers among Level 1, Level 2, and Level 3 as of the actual date of the events or change in circumstances that caused the transfer. During the three months ended March 31, 2012, and 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

As of March 31, 2012, and December 31, 2011, the carrying value of privately-held equity investments measured at fair value on a nonrecurring basis was $6.0 million and $0.4 million, respectively. These privately-held equity investments, which are normally carried at cost, were measured at fair value due to events and circumstances that the Company identified during the quarter as significantly impacting the fair value of the investments. The Company measured the fair value of its privately-held equity investments using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities, cash flow projections, and probability-weighted expected value based on the expected recoverability of the investments. As a result, the Company recognized an other-than-temporary non-cash impairment of $14.0 million in the three months ended March 31, 2012, and classified the investment as Level 3 assets due to the absence of quoted market prices and inherent lack of liquidity. The Company had no impairment charges against its privately-held equity investments in the three months ended March 31, 2011. The Company had no liabilities measured at fair value on a nonrecurring basis as of March 31, 2012 and December 31, 2011.

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).

Note 7. Derivative Instruments

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

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



	As of
	March 31, 2012		December 31, 2011
Cash flow hedges	$	122.4	$	184.3
Non-designated hedges	122.9		122.7
Total	$	245.3	$	307.0

Cash Flow Hedges

The Company uses 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 protect 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 interest and other income, net in its consolidated statements of comprehensive income. Cash flows from such hedges are classified as operating activities. All amounts within other comprehensive income (loss) are expected to be reclassified into earnings within the next 12 months.

The total fair value of the Company’s derivative assets recorded in other current assets on the condensed consolidated balance sheet as of March 31, 2012, and December 31, 2011, was $2.3 million and $0.4 million, respectively. The total fair value of the Company’s derivative liabilities located in other accrued liabilities on the condensed consolidated balance sheet as of March 31, 2012, and December 31, 2011, was $3.1 million and $9.6 million, respectively.

During the three months ended March 31, 2012 and 2011, the Company recognized a gain of $6.0 million and $5.2 million, respectively, in accumulated other comprehensive income for the effective portion of its derivative instruments and reclassified a loss of $3.5 million and a gain of $0.5 million, respectively, from other comprehensive income to operating expense in the condensed consolidated statements of comprehensive income.

The ineffective portion of the Company's derivative instruments recognized in its condensed consolidated statements of comprehensive income was immaterial during the three months ended March 31, 2012, and 2011.

Non-Designated Hedges

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 hedges do not qualify for special hedge accounting treatment. These derivatives are carried at fair value with changes recorded in other income and expense, 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. The derivatives have maturities of approximately two months.

During the three months ended March 31, 2012 and 2011, the Company recognized a net loss of $0.1 million and $0.2 million, respectively, within other expense and income, net, on its condensed consolidated statements of comprehensive income from non-designated derivative instruments.

Deferred product revenue is recorded net of the related costs of product revenue. Deferred service revenue represents customer payments made in advance for services, which include technical support, hardware and software maintenance, professional services, and training.

Restructuring Liabilities

In the third quarter of 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 primarily consisted of certain workforce reductions, and to a lesser extent, contract terminations.

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 2010 and 2009.

The Company recorded net restructuring charges of $2.0 million in the three months ended March 31, 2012, related to remaining restructuring activities from the 2011 Restructuring Plan, and recorded an adjustment of $0.3 million within restructuring in the condensed consolidated statements of comprehensive income during the three months ended March 31, 2011 in connection with the restructuring plan implemented in 2009. As of March 31, 2012, the remaining restructuring liability under the 2011 Restructuring Plan relates to severance costs to be paid out in 2012, as well as facilities-related charges under the two Restructuring Plans, which are expected to be completed by February 2015.

Restructuring charges were based on the Company's restructuring plans that were committed by management. 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 on the condensed consolidated balance sheets. The following table provides a summary of changes in the Company’s restructuring liability (in millions):

Note 10. Long-Term Debt and Financing

Long-Term Debt

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



	As of
	March 31, 2012
	Amount			Effective Interest Rates
Senior notes:
3.10% fixed-rate notes, due 2016	$	300.0		3.12	%

At March 31, 2012 and December 31, 2011, the estimated fair value of the notes included in long-term debt was approximately $1,097.6 million and $1,069.8 million, respectively, based on quoted market prices (Level 1).

Customer Financing Arrangements

The Company has customer financing arrangements to sell its accounts receivable to a major third-party financing provider. The

Table of Contents

Juniper Networks, Inc.

Notes to Condensed Consolidated Financial Statements (Continued)

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 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 $120.6 million and $174.8 million during the three months ended March 31, 2012, and 2011, respectively.

The Company received cash proceeds from the financing provider of $178.5 million and $194.3 million during the three months ended March 31, 2012, and 2011, respectively. The amounts owed by the financing provider were recorded as accounts receivable on the Company’s condensed consolidated balance sheets as of March 31, 2012, and December 31, 2011, was $101.3 million and $162.9 million, respectively.

The portion of the receivable financed that has not been recognized as revenue is accounted for as a financing arrangement and is included in other accrued liabilities and other long-term liabilities in the condensed consolidated balance sheets. As of March 31, 2012, and December 31, 2011, the estimated cash received from the financing provider not recognized as revenue from distributors was $40.9 million and $33.3 million, respectively.

Note 11. Equity

Stock Repurchase Activities

In February 2010, the Company’s Board of Directors (the “Board”) approved a stock repurchase program (the “2010 Stock Repurchase Program”) which authorized the Company to repurchase up to $1.0 billion of its common stock. This authorization was in addition to the stock repurchase program approved by the Board in March 2008 (the “2008 Stock Repurchase Program”), which also enabled the Company to repurchase up to $1.0 billion of the Company’s common stock.

The Company repurchased and retired approximately 2.4 million shares of its common stock at an average price of $21.75 per share for an aggregate purchase price of $51.6 million during the three months ended March 31, 2012 under the 2010 Stock Repurchase Program. The Company repurchased and retired approximately 4.8 million shares of its common stock at an average price of $42.14 per share for an aggregate purchase price of $200.2 million during the three months ended March 31, 2011 under the two stock repurchase programs. There were no remaining authorized funds under the 2008 Stock Repurchase Program and $162.2 million remaining authorized funds under the 2010 Stock Repurchase Program as of March 31, 2012.

Note 12. Employee Benefit Plans

Share-Based Compensation Plans

The Company’s share-based compensation plans include the 2006 Equity Incentive Plan (the “2006 Plan”), 2000 Nonstatutory Stock Option Plan (the “2000 Plan”), Amended and Restated 1996 Stock Plan (the “1996 Plan”), as well as various equity incentive plans assumed through acquisitions. Under these plans, the Company has granted (or in the case of acquired plans, assumed) stock options, RSUs, and PSAs. In addition, the Company’s 2008 Employee Stock Purchase Plan (the “2008 Purchase Plan”) permits eligible employees to acquire shares of the Company’s common stock at a 15% discount to the offering price (as determined in the 2008 Purchase Plan) through periodic payroll deductions of up to 10% of base compensation, subject to individual purchase limits of 6,000 shares in any twelve-month period or $25,000 worth of stock, determined at the fair market value of the shares at the time the stock purchase option is granted, in one calendar year.

The 2006 Plan, adopted and approved by the Company’s stockholders in May 2006, 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 each of May 2010 and 2011. As of March 31, 2012, the 2006 Plan had 64.9 million shares subject to currently outstanding equity awards and 22.2 million shares available for future issuance.

In connection with past acquisitions, the Company assumed stock option and RSU awards under the stock plans of the acquired companies. The Company exchanged those awards for Juniper Networks' stock options and RSUs. As of March 31, 2012, stock options and RSUs covering approximately 1.6 million shares of common stock were outstanding under awards assumed through the Company's past acquisitions.

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. The following table summarizes the Company’s stock option activity and related information as of and for the three months ended March 31, 2012 (in millions, except for per share amounts and years):



	Outstanding Options
	Number of Shares		Weighted Average Exercise Price per Share		Weighted Average Remaining Contractual Term (In Years)	Aggregate Intrinsic Value
Balance at January 1, 2012	38.6		$	23.98
Options granted	3.0		22.93
Options canceled	(0.5	)	28.48
Options exercised	(0.7	)	12.67
Options expired	(0.2	)	26.18

Exercisable options	27.7		$	22.47	2.9	$	87.7

Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the period, which was $22.88 per share as of March 31, 2012, and the exercise price multiplied by the number of related options. The pre-tax intrinsic value of options exercised, representing the difference between the fair market value of the Company’s common stock on the date of the exercise and the exercise price of each option, was $6.9 million for the three months ended March 31, 2012. Total fair value of options vested for the three months ended March 31, 2012, was $27.9 million.

Restricted Stock Units and Performance Share Awards Activities

RSUs generally vest over a period of three to four years from the date of grant, and PSAs generally vest after three years provided that certain annual performance targets and other vesting criteria are met. Until vested, RSUs and PSAs do not have the voting and dividend participation rights of common stock and the shares underlying the awards are not considered issued and outstanding.

The following table summarizes the Company’s RSU and PSA activity and related information as of and for the three months ended March 31, 2012 (in millions, except per share amounts and years):



	Outstanding RSUs and PSAs
	Number of Shares		Weighted Average Grant-Date Fair Value per Share		Weighted Average Remaining Contractual Term (In Years)	Aggregate Intrinsic Value

The number of shares subject to PSAs granted represents the aggregate maximum number of shares that may be issued pursuant to the award over its full term. The aggregate number of shares subject to these PSAs that would be issued if performance goals determined by the Compensation Committee are achieved at target is 0.9 million shares. Depending on achievement of such performance goals, the range of shares that could be issued under these awards is 0 to 2.2 million shares.

Shares Available for Grant

The following table presents the stock grant activity and the total number of shares available for grant under the 2006 Plan as of March 31, 2012 (in millions):



	Number of Shares

Employee Stock Purchase Plan

The Company's 2008 Purchase Plan is implemented in a series of offering periods, each six months in duration, or a shorter period as determined by the Board. Under the 2008 Purchase Plan, employees purchased approximately 1.7 million shares at an average per share price of $17.79 for the three months ended March 31, 2012, and 1.0 million shares at an average price of $23.89 for the three months ended March 31, 2011.

As of March 31, 2012, approximately 7.7 million shares had been issued and 4.3 million shares remained available for future issuance under the 2008 Purchase Plan.

Common Stock Reserved for Future Issuance

As of March 31, 2012, the Company had reserved an aggregate of approximately 93.0 million shares of common stock for future issuance under its equity incentive plans and the 2008 Purchase Plan.

Share-Based Compensation Expense

The Company determines the fair value of its stock options utilizing the Black-Scholes-Merton (“BSM”) option-pricing model, which incorporates various assumptions including 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 and on the terms and conditions of the stock awards granted to employees, as well as the potential effect from stock options that had not been exercised at the time. The Company determines the fair value of its RSUs and PSAs based upon the fair market value of the shares of the Company’s common stock at the date of grant.

The weighted average assumptions used and the resulting estimates of fair value for employee stock options and the employee stock purchase plan during the three months ended March 31, 2012 and 2011 were:



	Three Months Ended March 31,
	2012	2011
Employee Stock Options:
Volatility factor	46%	41%
Risk-free interest rate	0.8%	1.7%
Expected life (years)	4.2	4.1
Dividend yield	—	—
Fair value per share	$8.51	$14.43

Employee Stock Purchase Plan:
Volatility factor	51%	33%
Risk-free interest rate	0.1%	1.8%
Expected life (years)	0.5	0.5
Dividend yield	—	—
Weighted-average fair value per share	$6.38	$9.07

The Company expenses the cost of its stock options on a straight-line basis over the vesting period and expenses the cost of its RSUs ratably over the vesting period. With respect to PSAs, for the portion of the award attributable to each performance year, the Company recognizes PSA expense ratably over the remaining vesting period starting in the period in which the annual performance targets are set for each such performance year.

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. Employees meeting the eligibility requirements, as defined, may contribute up to the statutory limits of the year. The Company has matched employee contributions since January 1, 2001, currently matching 25% of all eligible employee contributions. All matching contributions vest immediately. The Company’s matching contributions to the plan totaled $6.6 million and $5.1 million in the three months ended March 31, 2012 and March 31, 2011, 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 on the condensed consolidated balance sheet. 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 interest and other income, net, and the offsetting compensation expense are recorded as operating expenses in the condensed consolidated results of operations. The deferred compensation liability under the NQDC plan was approximately $11.9 million and $9.3 million as of March 31, 2012, and December 31, 2011, respectively. For additional information regarding the Company's NQDC, see Note 5, Cash, Cash Equivalents, and Investments.

Note 13. 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 has reclassified segment operating results for 2011 to conform with certain 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, 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 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 includes 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 MobileNext^TM).

The CODM does not allocate to its business segments certain operating expenses managed separately at the corporate level. Direct costs and operating expenses, such as standard COGS, R&D, 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. Corporate unallocated charges includes: sales, marketing, and G&A costs, as well as share-based compensation, amortization of purchased intangible assets, restructuring and impairment charges, gains or losses on equity investments, other net income and expense, income taxes, or certain other charges. Segment contribution margin excludes these corporate unallocated charges.

Depreciation expense allocated to the PSD segment was $28.2 million and $26.0 million in the three months ended March 31, 2012 and March 31, 2011, respectively. Depreciation expense allocated to the SSD segment was $7.9 million and $8.0 million in the three months ended March 31, 2012 and March 31, 2011, respectively.

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



	Three Months Ended
	March 31,
	2012		2011
Americas:
United States	$	468.4	$	526.0

The Company tracks assets by physical location. The majority of the Company’s assets, excluding cash and cash equivalents and investments, as of March 31, 2012, and December 31, 2011, were attributable to U.S. operations. As of March 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 80%. 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.

Note 14. Income Taxes

The Company recorded a tax provision of $7.0 million and $41.3 million, or effective tax rates of 30.1% and 24.1% for the three months ended March 31, 2012 and 2011, respectively.

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

The effective tax rate for the three months ended March 31, 2011, differs from the federal statutory rate of 35% primarily due to the federal R&D credit and the benefit of earnings in foreign jurisdictions, which are subject to lower tax rates.

The gross unrecognized tax benefits increased by approximately $2.9 million for the three months ended March 31, 2012. In the same period, a benefit primarily related to expiration of statutes of limitation in the amount of approximately $3.4 million, including interest and penalties, impacted the effective tax rate.

The Company is currently under examination by the Internal Revenue Service ("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 March 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. For more information, please see Note 15, Commitments and Contingencies, under the heading “IRS Notices of Proposed Adjustments.”

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. It is reasonably possible that the balance of the gross unrecognized tax benefits will decrease by approximately $2.7 million within the next twelve months due to lapses of applicable statutes of limitation in multiple jurisdictions that the Company operated in. However, at this time, the Company is unable to make a reasonably reliable estimate of the timing of payments related to the remaining unrecognized tax liabilities due to uncertainties in the timing of tax audit outcomes.

Operating Leases

The Company leases its facilities under operating leases that expire at various times, the longest of which expires on November 30, 2022. Future minimum payments under the non-cancelable operating leases totaled $293.3 million as of March 31, 2012. Rent expense was $15.7 million and $14.8 million for the three months ended March 31, 2012 and March 31, 2011, respectively.

Purchase Commitments

In order to reduce manufacturing lead times and ensure adequate component supply, contract manufacturers utilized by the Company place non-cancelable, non-returnable (“NCNR”) orders for components based on the Company’s build forecasts. As of March 31, 2012, there were NCNR component orders placed by the contract manufacturers with a value of $136.4 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. If the components remain unused or the products remain unsold for specified periods, the Company may incur carrying charges or obsolete materials charges for components that the contract manufacturers purchased to build products to meet the Company’s forecast or customer orders. As of March 31, 2012, the Company had accrued $15.6 million based on its estimate of such charges.

Tax Liabilities

As of March 31, 2012, the Company had $111.4 million included in long-term liabilities in the condensed consolidated balance sheet for unrecognized tax positions. At this time, the Company is unable to make a reasonably reliable estimate of the timing of payments related to the additional $111.4 million in liability due to uncertainties in the timing of tax audit outcomes.

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

As of March 31, 2012, the Company held long-term debt with a carrying value of $999.1 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 5.95%. Interest on the notes is payable semiannually. See Note 10, Long-Term Debt and Financing, for further discussion of the Company's long-term debt.

Other Contractual Obligations

As of March 31, 2012, other contractual obligations primarily consisted of $29.2 million in indemnity-related and service related escrows, required by certain acquisitions completed in 2005 and 2010, $47.6 million in campus build-out obligations, and other miscellaneous commitments.

Guarantees

The Company enters into agreements with customers that contain indemnification provisions relating to potential situations where claims could be alleged that the Company’s products infringe the intellectual property rights of a third-party. The Company also has financial guarantees consisting of guarantees of product and service performance, guarantees related to third-party customer-financing arrangements, customs and duties guarantees, and standby letters of credit for certain lease facilities. As of March 31, 2012, and December 31, 2011, the Company had $19.3 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 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, the outcome of these matters is currently not determinable. 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, which could result in the need to adjust the liability and record additional expenses.

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. On January 9, 2012 the Court appointed City of Omaha Police and Fire Retirement System and City of Bristol Pension Fund as lead plaintiff. Lead plaintiff filed an amended complaint on February 13, 2012. The amended complaint alleges that defendants made false and misleading statements about Juniper's business and future prospects, and failed to adequately disclose the impact of certain changes in accounting rules. The amended complaint purports 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's common stock between July 20, 2010 and July 26, 2011, inclusive. On March 14, 2012, Defendants filed motions to dismiss. Plaintiffs filed their opposition to the motions on April 13, 2012. The motions are scheduled to be heard by the Court on July 19, 2012.

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. The motions are scheduled to be heard by the Court on July 27, 2012.

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

In 2011, as a result of its audit of the Company's U.S. federal income tax returns for the 2005 and 2006 fiscal years, the IRS issued a Preliminary Notice of Deficiency (“PNOD”) regarding the Company's transfer pricing transactions under its intercompany R&D cost sharing arrangement related to the license of intangibles acquired in 2005. The asserted changes would affect the Company's income tax liabilities for tax years subsequent to 2004. Because of the PNOD, the estimated incremental tax liabilities for all relative tax years would be approximately $92 million, excluding interest and penalties. The Company has filed a protest to the proposed deficiency with the IRS.

In 2009, the Company received a PNOD from the IRS claiming that the Company owes additional taxes, plus interest and possible penalties, for the 2004 tax year based on a transfer pricing transaction related to the license of acquired intangibles under an intercompany R&D cost sharing arrangement. The asserted changes to the Company's 2004 tax year would affect the Company's income tax liabilities in tax years subsequent to 2003. In addition, the Company has not reached a final resolution with the IRS on an adjustment the IRS proposed for the 1999 and 2000 tax years. Because of the PNOD, the estimated incremental tax liability would be approximately $807 million, excluding interest and penalties. The Company has filed a protest to the PNOD, which is under review by the Appeals Division of the IRS.

The Company strongly believes the IRS' position with regard to transfer pricing transactions for the Company's 2004 through 2006 fiscal years are inconsistent with applicable tax laws, judicial precedent and existing Treasury regulations, and that the Company's previously reported income tax provisions for the years in question are appropriate. However, there can be no assurance that these matters will be resolved in the Company's favor. Regardless of whether these matters are resolved in the Company's favor, the final resolution of these matters could be expensive and time-consuming to defend and/or settle. While the Company believes it has provided adequately for these matters, there is still a possibility that an adverse outcome from these matters could have a material effect on its results of operations and financial condition.

In September 2008, as part of its ongoing audit of the U.S. federal income tax return for the 2004 fiscal year, the IRS issued a Notice of Proposed Adjustment (“NOPA”) regarding the Company's business credits. The Company believes that it has adequately provided for any reasonable foreseeable outcome related to this proposed adjustment.

The Company is also under routine examination by certain state and non-U.S. tax authorities. The Company believes that it has adequately provided for any reasonably foreseeable outcome related to these audits.

Note 16. Subsequent Event

Stock Repurchases

Subsequent to March 31, 2012, through the filing of this report, the Company repurchased 2.2 million shares of its common stock, for $44.0 million at an average purchase price of $20.09 per share, under its 2010 Stock Repurchase Program. Repurchases of 2.0 million shares were settled prior to the filing of this report and the remaining shares will be settled after the filing date. The Company's 2010 Stock Repurchase Program had remaining authorized funds of $122.2 million as of the filing date. Purchases under the Company's 2010 Stock Repurchase Program are subject to a review of the circumstances in place at the time and will be made from time to time as permitted by securities laws and other legal requirements. This program may be discontinued at any time.

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

Forward-Looking Statements

This Quarterly Report on Form 10-Q (“Report”), including the “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” contains forward-looking statements regarding future events and the future results of Juniper Networks, Inc. (“we,” “us,” "Juniper," or the “Company”) that are based on our current expectations, estimates, forecasts, and projections about our business, our results of operations, the industry in which we operate, and the beliefs and assumptions of our management. Words such as “expects,” “anticipates,” “targets,” “goals,” “projects,” “would,” “could,” “intends,” “plans,” “believes,” “seeks,” “estimates,” variations of such words, and similar expressions are intended to identify such forward-looking statements. These forward-looking statements are only predictions and are subject to risks, uncertainties, and assumptions that are difficult to predict. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in this Report under the section entitled “Risk Factors” in Item 1A of Part II and elsewhere, and in other reports we file with the SEC, specifically our most recent Annual Report on Form 10-K. While forward-looking statements are based on reasonable expectations of our management at the time that they are made, you should not rely on them. We undertake no obligation to revise or update publicly any forward-looking statements for any reason.

The following discussion is based upon our unaudited Condensed Consolidated Financial Statements included in Part 1, Item I, of this Report, which have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In the course of operating our business, we routinely make decisions as to the timing of the payment of invoices, the collection of receivables, the manufacturing and shipment of products, the fulfillment of orders, the purchase of supplies, and the building of inventory and spare parts, among other matters. Each of these decisions has some impact on the financial results for any given period. In making these decisions, we consider various factors, including contractual obligations, customer satisfaction, competition, internal and external financial targets and expectations, and financial planning objectives. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosure of contingencies. On an ongoing basis, we evaluate our estimates, including those related to sales returns, pricing credits, warranty costs, allowance for doubtful accounts, impairment of long-term assets, especially goodwill and intangible assets, contract manufacturer exposures for carrying and obsolete material charges, assumptions used in the valuation of share-based compensation, and litigation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. For further information about our accounting policies and estimates, see Note 2, Summary of Significant Accounting Policies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Annual Report on Form 10-K for the year ended December 31, 2011, and in the section entitled “Critical Accounting Policies and Estimates” included in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Actual results may differ from these estimates under different assumptions or conditions.

To aid in understanding our operating results for the periods covered by this Report, we have provided a summary of our business and market environment along with a financial results overview. These sections should be read in conjunction with the more detailed discussion and analysis of our consolidated financial condition and results of operations in this Item 2, our “Risk Factors” section included in Item 1A of Part II, and our unaudited condensed consolidated financial statements and notes included in Item 1 of Part I of this report.

Business and Market Environment

At Juniper Networks, we design, develop, and sell products and services that together provide our customers with a high-performance network infrastructure built on simplicity, security, openness, and scale. We serve the high-performance networking requirements of global service providers, enterprises, governments, and research and public sector organizations that view the network as critical to their success. Our core competencies in hardware systems, silicon design, network architecture, and our open cross-network software platform are helping customers achieve unmatched performance, greater choice and flexibility while reducing overall total cost of ownership.

We do business in three geographic regions: Americas, Europe, Middle East and Africa (“EMEA”), and Asia Pacific (“APAC”). Beginning in the first quarter of 2012, we aligned our organization structure to focus on our platform and software strategy, which resulted in two business segments: Platform Systems Division ("PSD") and Software Solutions Division ("SSD"). Our 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, wireless local area network ("WLAN"), branch, and customer premise equipment level. Our SSD segment offers solutions that address a broad

Table of Contents

array of our customers' priorities, from protecting the users, applications, and data on the network to providing network services across a distributed infrastructure. Both segments offer worldwide services, including technical support and professional services, as well as educational and training programs to our customers.

Over the past three years we have aligned our organization around a common vision for the new network and the organizational structure we have in place will effectively drive our innovative portfolio and support our customers' next-generation network requirements. Together, our high-performance product and service offerings help our customers to convert legacy networks that provide commoditized services into more valuable assets that provide differentiation, value, increased performance, reliability, and security to end-users. We remain dedicated to uncovering new ideas and innovations that will serve the exponential demands of the networked world and we will continue to build solutions that center on simplification, automation, and open innovation.

We saw traction with our new product offerings during the first quarter of 2012, including our QFabric (“QFX”) solutions, T4000 Core Routers, and PTX Series Packet Transport switches. Additionally, in the first quarter of 2012, Juniper announced the new ACX Series router, which extends network intelligence closer to the subscriber and features an open, standards-based management system with SDK-enabled programmability to enable rapid third party innovation. We expect to begin shipping ACX Series routers in the second half of 2012.

In the first quarter of 2012, we continued to experience an uncertain global macroeconomic environment in which our customers exercised care and conservatism in their investment prioritization and project deployments. We expect that our customers will continue to be cautious with their capital spending in the near term. Nevertheless, we believe the underlying fundamentals of our business remain intact and we are focused on executing our strategy to address the market trends of mobile Internet and cloud computing. As part of that strategy, we extended our security portfolio with an intrusion deception system capable of detecting an attacker before an attack is in process through the acquisition of a privately-held company, Mykonos Software, Inc. ("Mykonos"), in February 2012.

•

Net Revenues: Our net revenues decreased in Americas and APAC, offset by a slight increase in EMEA. In addition, revenue decreased in both service provider and enterprise markets for the three months ended March 31, 2012, compared to the same periods in 2011. These decreases were primarily due to decreased sales of our T, M, and MX Series routers, partially offset by the increase in sales of our High-End SRX products, EX Series, and QFX Series switching products.

•

Operating Income: Our operating income decreased as a percentage of revenues in the three months ended March 31, 2012, compared to the same period in 2011, primarily due to lower net revenue, gross margin, as well as increased expenses attributable to our investments in Sales and Marketing and Research and Development ("R&D") as we continue to increase sales coverage for our new products and invest in our innovative portfolio.

•

Net Income Attributable to Juniper Networks and Net Income Per Share Attributable to Juniper Networks Common Stockholders: The decrease in net income attributable to Juniper Networks in the three months ended March 31, 2012, compared to the same period in 2011, reflects the lower operating income discussed above, and the impairment of a privately-held investment that we judged to be other-than-temporary during the first quarter of 2012.


•	Operating Cash Flows: Operating cash flows decreased in the three months ended March 31, 2012, compared to the same period in 2011, primarily due to lower net income and cash collections, timing of payments to our vendors, and interest payment on our debt obligations.


•	Deferred Revenue: Total deferred revenue increased by $32.6 million to $999.6 million as of March 31, 2012, compared to $967.0 million as of December 31, 2011, due to an increase in deferred service revenue driven by service contract renewals, partially offset by a decrease in deferred product revenue.


•	Stock Repurchase Plan Activity: Under our stock repurchase program, we repurchased approximately 2.4 million shares of our common stock on the open market at an average price of $21.75 per share for an aggregate purchase price of $51.6 million during the three months ended March 31, 2012.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires us to make judgments, assumptions, and estimates that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. These estimates and assumptions are based on current facts, historical experience, and various other factors that we believe are reasonable under the circumstances to determine reported amounts of assets, liabilities, revenue and expenses that are not readily apparent from other sources. To the extent there are material differences between our estimates and the actual results, our future consolidated results of operations may be affected.

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


•	Revenue recognition;


•	Contract Manufacturer Liabilities;


•	Warranty Costs;


•	Goodwill and Purchased Intangible Assets;


•	Share-Based Compensation;


•	Income Taxes; and


•	Loss Contingencies.

During the three months ended March 31, 2012, there were no significant changes to our critical accounting policies and estimates. Please refer to Management's Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2011, for a complete discussion of our critical accounting policies and estimates.

Recent Accounting Pronouncements

See Note 2, Summary of Significant Accounting Policies, in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q, for a full description of recent accounting pronouncements, including the actual and expected dates of adoption and estimated effects on our consolidated results of operations and financial condition, which is incorporated herein by reference.

Results of Operations

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



	Three Months Ended March 31,
	2012			2011			$ Change			% Change
Net revenues:
Product	$	771.9		$	877.4		$	(105.5	)	(12	)%

Percentage of net revenues	25.2		%	20.4		%
Total net revenues	$	1,032.5		$	1,101.6		$	(69.1	)	(6	)%

The decrease in product revenues in the three months ended March 31, 2012, was primarily the result of a decline in sales of our T, M and MX Series routers, partially offset by an increase in our High-End SRX products, EX Series, and QFX Series switches. The decrease was primarily due to the overall weakness in the service provider and enterprise markets during the first quarter of 2012 attributable to the timing of capital expenditures by our customers. In the three months ended March 31, 2012, the increase in service revenue was primarily driven by strong contract renewals.

Net Revenues by Market and Customer

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



	Three Months Ended March 31,
	2012			2011			$ Change			% Change
Service Provider	$	685.6		$	742.2		$	(56.6	)	(8	)%
Percentage of net revenues	66.4		%	67.4		%
Enterprise	346.9			359.4			(12.5		)	(3	)%
Percentage of net revenues	33.6		%	32.6		%
Total	$	1,032.5		$	1,101.6		$	(69.1	)	(6	)%

We sell our high-performance network products and service offerings from our PSD and SSD segments to two primary markets: service provider and enterprise. Determination of which market a particular revenue transaction relates to is based primarily upon the customer's industrial classification code, but may also include subjective factors such as the intended use of the product. The service provider market generally includes wireline, wireless, and cable operators, as well as major Internet content and application providers, including those that provide social networking and search engine services. The enterprise market generally comprises businesses; federal, state, and local governments; and research and education institutions.

Net revenue from sales to the service provider market in the three months ended March 31, 2012, decreased compared to the same period in 2011, primarily due to reduced routing purchases by some of our international and content service providers.

We also experienced a decrease in revenues from the enterprise market during the three months ended March 31, 2012, compared to the same period in 2011, resulting from decreased sales of our branch Firewall products and MX Series routers, partially offset by increased sale in our EX Series switches.

In the three months ended March 31, 2012, Verizon Communications, Inc. accounted for 15.3% of our net revenues. In the three months ended March 31, 2011, no single customer accounted for 10% or more of our net revenues.

Percentage of net revenues	18.8		%	20.1		%
Total	$	1,032.5		$	1,101.6		$	(69.1	)	(6	)%

Net revenue in the Americas decreased in the three months ended March 31, 2012, compared to the same periods in 2011, primarily due to decreased sales to certain content service providers in the United States. The decrease was primarily due to lower sales of our T, MX, and M Series routers in the three months ended March 31, 2012.

The increase in EMEA net revenues during the three months ended March 31, 2012, were primarily due to increased sales in Eastern Europe, and to a lesser extent, Finland and UAE. We continued to see traction in revenue growth from a top service provider in Eastern Europe, which span a broad range of our product portfolio.

The decrease in net revenues in APAC in the three months ended March 31, 2012, compared to the same period in 2011, was due to decrease in both service provider and enterprise demand for our T and MX Series routers in the three months ended March 31, 2012. The decrease was primarily due to a large service provider deployment in Japan in the three months ended March 31, 2011.

Gross Margins

Total gross margin	$	634.1		$	735.9		$	(101.8	)	(14	)%
Percentage of net revenues	61.4		%	66.8		%

Product gross margin percentage decreased in the three months ended March 31, 2012, compared to the same periods in 2011, primarily due to the shift in product mix to lower margin products, geographical mix, as well as inventory related costs. Service gross margin percentage decreased primarily due to higher material and repair costs for fulfillment of our service contract obligations.

________________________

N/M = not meaningful

R&D expense increased in the three months ended March 31, 2012, compared to the same periods in 2011, was primarily due to increase personnel expenses as well as a slight increase in engineering headcount by 0.6% from 4,175 as of March 31, 2011, to 4,202 employees as of March 31, 2012, as we continue to invest in new product innovation and expansion of our product portfolio.

Sales and marketing expenses increased in the three months ended March 31, 2012, compared to the same periods in 2011, primarily due to an increase in personnel related expenses, partially offset by lower commission during the first quarter of 2012.

General and administrative expenses increased in the three months ended March 31, 2012, compared to the same periods in 2011, primarily due to an increase of outside professional services, which include legal and consulting fees, and to a lesser extent, personnel related expenses.

Amortization of purchased intangible assets was relatively flat in the three months ended March 31, 2012, compared to the same periods in 2011, primarily due to certain intangible assets which were fully amortized in 2011, partially offset by the addition of intangible assets from acquisitions completed in the first quarter of 2012. Acquisition-related charges were lower in the three months ended March 31, 2012, compared to the three months ended March 31, 2011, primarily to due higher acquisition related costs for our acquisitions completed during the fourth quarter of 2010 and in the first quarter of 2011. See Note 3, Business Combinations, in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q, for further discussion of these acquisitions.

We incurred $2.0 million of net restructuring charges in the three months ended March 31, 2012, as we continued to execute our 2011 Restructuring Plan, which was implemented in the third quarter of 2011 to better align our business operations with macroeconomic and other market conditions. These restructuring charges were primarily related to workforce reductions, and to a lesser extent contract terminations. As we complete the alignment next quarter, we may incur additional severance and facility costs, ranging from $6 million to $10 million in the aggregate.

	2012		2011		$ Change		% Change
Cost of revenues - Product	$	1.1	$	1.0	$	0.1	10	%
Cost of revenues - Service	5.2		3.9		1.3		33	%
Research and development	25.8		22.3		3.5		16	%
Sales and marketing	21.9		13.2		8.7		66	%
General and administrative	11.0		8.6		2.4		28	%
Total	$	65.0	$	49.0	$	16.0	33	%

Share-based compensation expense increased in the three months ended March 31, 2012, compared to the same periods in 2011, primarily due to the increase in awards granted.

Effect of Foreign Currency

The change in operating expenses, including cost of service revenue, R&D, sales and marketing, and G&A expenses, due to foreign currency fluctuations was approximately 1% in the three months ended March 31, 2012 and was immaterial for the three months ended March 31, 2011.

Other Income and Expense, Net and Income Tax Provision

The following table presents other income and expense, net and income tax provision (in millions, except percentages):



	Three Months Ended March 31,
	2012			2011			$ Change			% Change
Interest income	$	2.8		$	2.4		$	0.4		17	%
Interest expense	(14.2		)	(6.5		)	(7.7		)	N/M
Other	(13.0		)	(2.4		)	(10.6		)	N/M
Total other (expense) income, net	$	(24.4	)	$	(6.5	)	$	(17.9	)	N/M
Percentage of net revenues	(2.4		)%	(0.6		)%

Income tax provision	$	7.0		$	41.3		$	(34.3	)	(83	)%
Effective tax rate	30.1		%	24.1		%

Interest income primarily includes interest income from our cash, cash equivalents, and investments. Interest expense, primarily consisting of interest on debt outstanding, increased in the three months ended March 31, 2012, compared to the same periods in 2011, primarily due to the issuance of our debt near the end of the first quarter of 2011. Other typically consists of investment and foreign exchange gains and losses and other non-operational income and expense items. In comparison to the three months ended March 31, 2011, the increase in other was primarily due to an other-than-temporary non-cash impairment on a privately-held equity investment of $14.0 million recorded in the three months ended March 31, 2012.

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

The effective tax rate for the three months ended March 31, 2011 differs from the federal statutory rate of 35% primarily due to the federal R&D credit and the benefit of earnings in foreign jurisdictions, which are subject to lower tax rates.

For a further explanation of our income tax provision, see Note 14, Income Taxes, in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report.

During the three months ended March 31, 2012, PSD product revenues decreased compared to the same period in 2011, due to lower spending by some of our international and content service provider customers in the APAC and Americas regions, partially offset by continued demand for our switching products. The decreased was attributable to the decline in sales of our T, M, and MX Series routers, partially offset by the increase in sale of our EX Series and QFX Series switching products.

During the three months ended March 31, 2012, PSD service revenues increased compared to the same period in 2011. The increase was mainly attributable to stronger contract renewal on support services during the first quarter of 2012.

PSD contribution margin as a percent of PSD revenues decreased in the three months ended March 31, 2012, compared to the same period in 2011 due to the decline in revenues and to a lesser extent, product and geographical mix, and higher R&D expenses.

During the three months ended March 31, 2012, SSD product revenues was relatively flat compared to the same period in 2011. High-End SRX products revenue remained strong driven by service provider demand. This was partially offset by the decline in sales of our High-End Firewall and Pulse products.

During the three months ended March 31, 2012, SSD service revenues increased compared to the same period in 2011. The increase was mainly attributed to stronger contract renewal on support services during the period.

SSD contribution margin as a percent of SSD revenues decreased slightly in the three months ended March 31, 2012, compared to the same period in 2011. The decrease was attributable to increasing our R&D spend, to continue to expand our product portfolio, at a higher rate than our revenues.

Liquidity and Capital Resources

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



	March 31, 2012		December 31, 2011		Change			% Change
Working capital	$	2,870.3	$	2,973.0	$	(102.7	)	(3	)%
Deferred revenue	999.6		967.0		32.6			3	%

Total cash, cash equivalents and investments	4,215.8		4,292.4		(76.6		)	(2	)%
Long-term debt	999.1		999.0		0.1			—	%
Net cash, cash equivalents, and investments	$	3,216.7	$	3,293.4	$	(76.7	)	(2	)%

The significant components of our working capital are cash and cash equivalents, short-term investments, and accounts receivable, reduced by accounts payable, accrued liabilities, and short-term deferred revenue. Working capital decreased by $102.7 million in the three months ended March 31, 2012, primarily due to cash payments for acquisitions completed during the first quarter of 2012 and repurchases of our outstanding common stock.

DSO as of March 31, 2012 decreased by 7 days, or 15% comparing to December 31, 2011. The decrease was primarily due to improvement in overall shipment linearity.

Summary of Cash Flows

In the three months ended March 31, 2012, cash and cash equivalents increased by $2.7 million. This increase was the result of cash generated by our operating of $102.3 million, offset by cash used in investing and financing activities of $93.3 million and $6.3 million, respectively.

Operating Activities

Cash flows from operations in the three months ended March 31, 2012, was $102.3 million compared to $239.7 million for the same period in 2011. The decrease of $137.4 million was primarily due to lower net income and cash collections, timing of payments to our vendors, and interest payment on our debt obligation. The decrease is also attributable to the increase of our inventory purchases.

Investing Activities

For the three months ended March 31, 2012, net cash used in investing activities was $93.3 million compared to $209.2 million in the three months ended March 31, 2011. The change was primarily due to higher spending on acquisitions and property and equipment in the three months ended March 31, 2012, as compared to the same period a year ago, partially offset by higher proceeds from sales and maturities, net of purchases, of our investments.

Financing Activities

Net cash used in financing activities was $6.3 million for the three months ended March 31, 2012 compared to net cash generated in financing activities of $1,102.1 million for the same period in 2011. The change was primarily due to the issuance of our long-term debt on March 5, 2011, and to a lesser extent, cash proceeds from common stock issued to our employees during the first quarter of 2012. These changes were partially offset by lower share repurchases of our common stock in the first quarter of 2012 in comparison to the first quarter of 2011. For further discussion of our long-term debt, see Note 10, Long-Term Debt and Financing, in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Quarterly Report on Form 10-Q.

Stock Repurchase Activities

In February 2010, our Board of Directors (the "Board") approved a stock repurchase program (the “2010 Stock Repurchase Program”), which authorized us to repurchase up to $1.0 billion of our common stock. This authorization was in addition to the stock repurchase program approved by the Board in March 2008 (the “2008 Stock Repurchase Program”), which also enabled us to repurchase up to $1.0 billion of our common stock.

We repurchased and retired approximately 2.4 million shares of our common stock at an average price of $21.75 per share for an aggregate purchase price of $51.6 million during the three months ended March 31, 2012 under our 2010 Stock Repurchase Program. As of March 31, 2012, there were no remaining authorized funds under the 2008 Stock Repurchase Program and $162.2 million remaining authorized funds under the 2010 Stock Repurchase Program.

Deferred Revenue

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



	As of
	March 31, 2012			December 31, 2011
Deferred product revenue:
Undelivered product commitments and other product deferrals	$	286.4		$	288.1
Distributor inventory and other sell-through items	114.0			134.0
Deferred gross product revenue	400.4			422.1
Deferred cost of product revenue	(118.4		)	(136.9		)
Deferred product revenue, net	282.0			285.2
Deferred service revenue	717.6			681.8
Total	$	999.6		$	967.0

Deferred gross product revenue as of March 31, 2012, decreased $21.7 million compared to December 31, 2011, primarily due to the release of several large product commitments delivered during the three months ended March 31, 2012. Total deferred service revenue increased $35.8 million compared to December 31, 2011, primarily due to an increase in new service contracts and renewal of existing contracts.

Contractual Obligations

There have been no significant changes during the three months ended March 31, 2012, to the contractual obligations disclosed in Management's Discussion and Analysis of Financial Condition and Results of Operations, set forth in Part II, Item 7, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2011. The summary of our long-term debt obligations and related interest are presented as follows (in millions):



	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years		Other
Long-term debt	$	1,000.0	$	—	$	—	$	300.0	$	700.0	$	—
Interest payment on long-term debt	849.7		46.9		93.8		84.1		624.9		—

Liquidity and Capital Resource Requirements

Liquidity and capital resources may be impacted by our operating activities as well as acquisitions and investments in strategic relationships that we have made or we may make in the future. Additionally, if we were to repurchase additional shares of our common stock under the 2010 Stock Repurchase Program, our liquidity may be impacted. As of March 31, 2012, 51% of our cash and investment balances are held outside of the U.S., which may be subject to U.S. taxes if repatriated.

In August 2010, we filed a $1.5 billion shelf registration statement with the SEC. In March 2011, we issued notes in the amount of $1.0 billion under the shelf registration statement. Therefore, while we have no current plans to do so, we may issue up to

Table of Contents

$500 million in additional securities under the shelf registration statement. The shelf registration statement is intended to give us flexibility to take advantage of financing opportunities as needed or deemed desirable in light of market conditions. Any additional offerings of securities under the shelf registration statement will be made pursuant to a prospectus.

We have been focused on managing our annual equity usage as a percentage of the common stock outstanding to align with peer group competitive levels and have made changes in recent years to reduce the number of shares underlying the equity awards we grant. Our intention for fiscal year 2012 is to target the number of shares underlying equity awards granted on an annual basis at 2.75% or less of our common stock outstanding. Based upon shares underlying our grants to date of options, RSUs, and PSAs (counting only the on-target measure of such PSAs), we believe we are on track with respect to this goal for 2012.

Based on past performance and current expectations, we believe that our existing cash and cash equivalents, short-term, and long-term investments (which includes the proceeds of the issuance of the notes), together with cash generated from operations as well as cash generated from the exercise of employee stock options and purchases under our employee stock purchase plan will be sufficient to fund our operations and anticipated growth for at least the next 12 months. We believe our working capital is sufficient to meet our liquidity requirements for capital expenditures, commitments, and other liquidity requirements associated with our existing operations during the same period. However, our future liquidity and capital requirements may vary materially from those now planned depending on many factors, including:


•	level and mix of our product, sales, and gross profit margins;


•	our business, product, capital expenditures and R&D plans;


•	repurchases of our common stock;


•	incurrence and repayment of debt and related interest obligations;


•	litigation expenses, settlements, and judgments, or similar items related to resolution of tax audits;


•	volume price discounts and customer rebates;


•	accounts receivable levels that we maintain;


•	acquisitions and/or funding of other businesses, assets, products, or technologies;


•	changes in our compensation policies;


•	capital improvements for new and existing facilities;


•	technological advances;


•	our competitors' responses to our products and/or pricing;


•	our relationships with supplies, partners, and customers;


•	possible future investments in raw material and finished goods inventories;


•	expenses related to future restructuring plans, if any;


•	tax expense associated with share-based awards;


•	issuance of share-based awards and the related payment in cash for withholding taxes in the current year and possibly during future years;


•	level of exercises of stock options and stock purchases under our equity incentive plans; and


•	general economic conditions and specific conditions in our industry and markets, including the effects of disruptions in global credit and financial markets, international conflicts, and related uncertainties.

Factors That May Affect Future Results

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

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our exposures to market risk have not changed materially since December 31, 2011. For quantitative and qualitative disclosures about market risk, see Item 7A Quantitative and Qualitative Disclosures About Market Risk, in our Annual Report on Form 10-K for the year ended December 31, 2011.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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

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

Changes in Internal Controls

There were no changes in our internal control over financial reporting that occurred during the first quarter of 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

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

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

The information set forth under “Legal Proceedings” section in Note 15, Commitments and Contingencies, in Notes to Condensed Consolidated Financial Statements in Item 1 Part I of this Quarterly Report on Form 10-Q, is incorporated herein by reference.

Item 1A. Risk Factors

Factors That May Affect Future Results

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

Our quarterly results are unpredictable and subject to substantial fluctuations, and, as a result, we may fail to meet the expectations of securities analysts and investors, which could adversely affect the trading price of our common stock.

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

The factors that may cause our quarterly results to be unpredictable include, but are not limited to: limited visibility into customer spending plans, changes in the mix of products and services sold, changes in geographies in which our products and services are sold, changing market and economic conditions, current and potential customer consolidation, competition, customer concentration, long sales and implementation cycles, regional economic and political conditions, and seasonality. For example, many companies in our industry experience adverse seasonal fluctuations in customer spending, particularly in the first and third quarters.

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

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

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

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

Table of Contents

condition, and results of operations.

A limited number of our customers comprise a significant portion of our revenues and any decrease in revenues from these customers could have an adverse effect on our net revenues and operating results.

A substantial majority of our net revenues depend on sales to a limited number of customers and distribution partners. For example, Verizon accounted for greater than 15% of our net revenues in the first quarter of 2012. Changes in the business requirements, vendor selection, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased) of our key customers could significantly decrease sales to such customers or could lead to delays or cancellations of planned purchases of our products or services, which increases the risk of quarterly fluctuations in our revenues and operating results. Any of these factors could adversely affect our business, financial condition, and results of operations.

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

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

A customer's decision to purchase certain of our products, particularly new products, involves a significant commitment of its resources and a lengthy evaluation and product qualification process. As a result, the sales cycle may be lengthy. In particular, customers making critical decisions regarding the design and implementation of large network deployments may engage in very lengthy procurement processes that may delay or impact expected future orders. Throughout the sales cycle, we may spend considerable time educating and providing information to prospective customers regarding the use and benefits of our products. Even after making the decision to purchase, customers may deploy our products slowly and deliberately. Timing of deployment can vary widely and depends on the skill set of the customer, the size of the network deployment, the complexity of the customer's network environment, and the degree of hardware and operating system configuration necessary to deploy the products. Customers with large networks usually expand their networks in large increments on a periodic basis. Accordingly, we may receive purchase orders for significant dollar amounts on an irregular basis. These long cycles, as well as our expectation that customers will tend to sporadically place large orders with short lead times, may cause revenues and operating results to vary significantly and unexpectedly from quarter-to-quarter.

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

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

In addition, actual or speculated consolidation among competitors, or the acquisition of our partners and/or resellers by competitors, can increase the competitive pressures faced by us as customers may delay spending decisions. In this regard, Ericsson acquired Redback in 2007, and Brocade acquired Foundry Networks in 2009. A number of our competitors have substantially greater resources and can offer a wider range of products and services for the overall network equipment market than we do. If we are unable to compete successfully against existing and future competitors on the basis of product offerings or price, we could experience a loss in market share and revenues and/or be required to reduce prices, which could reduce our gross margins, and which could materially and adversely affect our business, financial condition, and results of operations.

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

We expect our product gross margins to vary from quarter-to-quarter, and the gross margins we have achieved in recent years may not be sustainable and may be adversely affected in the future by numerous factors, including customer and product mix shifts, increased price competition in one or more of the markets in which we compete, increases in material or labor costs, excess product component or obsolescence charges from our contract manufacturers, increased costs due to changes in

Table of Contents

component pricing or charges incurred due to component holding periods if we do not accurately forecast product demand, warranty related issues, or our introduction of new products or entry into new markets with different pricing and cost structures.

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

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

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

Our future success is highly dependent upon establishing and maintaining successful relationships with a variety of value-added and other reseller and distribution partners, including our worldwide strategic partners such as Ericsson, IBM, and NSN. The majority of our revenues are derived through value-added resellers and distributors, most of which also sell our competitors’ products. Our revenues depend in part on the performance of these partners. The loss of or reduction in sales to our value-added resellers or distributors could materially reduce our revenues. For example, in 2006, one of our largest resellers, Lucent, was acquired by Alcatel, a competitor of ours. As a result of the merger, Lucent became a competitor, their resale of our products declined, and we ultimately terminated our reseller agreement with Lucent. Our competitors may in some cases be effective in providing incentives to current or potential resellers and distributors to favor their products or to prevent or reduce sales of our products. If we fail to develop and maintain relationships with our partners, fail to develop new relationships with value-added resellers and distributors in new markets, or expand the number of distributors and resellers in existing markets, fail to manage, train or motivate existing value-added resellers and distributors effectively, or if these partners are not successful in their sales efforts, sales of our products may decrease, and our business, financial condition, and results of operations would suffer.

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

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

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

Some of our business processes depend upon our information technology ("IT") systems, the systems, and processes of third parties, and on the interfaces of our systems with the systems of third parties. For example, our order entry system feeds information into the systems of our contract manufacturers, which enables them to build and ship our products. If those systems fail or are interrupted, our processes may function at a diminished level or not at all. This could negatively impact our ability to ship products or otherwise operate our business, and our financial results could be harmed. For example, although it did not adversely affect our shipments, an earthquake in late December of 2006 disrupted our communications with China, where a significant part of our manufacturing occurs.

Table of Contents

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

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

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

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

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

During periods of high demand for electronic products, component shortages are possible, and the predictability of the availability of such components may be limited. Any future growth in our business and the economy is likely to create greater pressures on us and our suppliers to accurately forecast overall component demand and to establish optimal component levels. If shortages or delays persist, the price of these components may increase, or the components may not be available at all. We may not be able to secure enough components at reasonable prices or of acceptable quality to build new products in a timely manner, and our revenues and gross margins could suffer until other sources can be developed. For example, from time to time, we have experienced component shortages that resulted in delays of product shipments. We currently purchase numerous key components, including ASICs, from single or limited sources. The development of alternate sources for those components is time-consuming, difficult, and costly. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. In the event of a component shortage or supply interruption from these suppliers, we may not be able to develop alternate or second sources in a timely manner. If we are unable to buy these components in quantities sufficient to meet our requirements on a timely basis, we will not be able to deliver product to our customers, which would seriously affect present and future sales, which would, in turn, adversely affect our business, financial condition, and results of operations.

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

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

In the ordinary course of business, we store sensitive data, including intellectual property, our proprietary business information and that of our customers, suppliers and business partners on our networks. The secure maintenance of this information is critical to our operations and business strategy. Increasingly, companies, including Juniper Networks, are subject to a wide variety of attacks on their networks on an ongoing basis. Despite our security measures, Juniper Networks' information technology and infrastructure may be vulnerable to penetration or attacks by computer programmers and hackers, or breached

Table of Contents

due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks, creating system disruptions or slowdowns and exploiting security vulnerabilities of our products, and the information stored on our networks could be accessed, publicly disclosed, lost or stolen. In addition, sophisticated hardware and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including "bugs" and other problems that could unexpectedly interfere with the operation of our networks.

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

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

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

In addition, environmental regulations relevant to electronic equipment manufacturing or operations may impact our business and financial condition adversely. For instance, the European Union has adopted WEEE and ROHS regulations, which require producers of electrical and electronic equipment to assume responsibility for collecting, treating, recycling and disposing of products when they have reached the end of their useful life, and REACH regulations, which regulate handling of certain chemical substances that may be used in our products. In addition, some governments have regulations prohibiting government entities from purchasing security products that do not meet specified indigenous certification criteria, even though those criteria may be in conflict with accepted international standards. Similar regulations are in effect or under consideration in several jurisdictions where we do business.

The adoption and implementation of such regulations could decrease demand for our products, increase the cost of building and selling our products and impact our ability to ship products into affected areas and recognize revenue in a timely manner. Any of these impacts could have a material adverse effect on our business, financial condition, and results of operations.

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

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

If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products and product

Table of Contents

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

We cannot guarantee that we will be able to anticipate future technological shifts, market needs and opportunities or be able to develop new products or product enhancements to meet such technological shifts, needs or opportunities in a timely manner or at all. If we fail to anticipate market requirements or fail to develop and introduce new products or product enhancements to meet those needs in a timely manner, it could cause us to lose customers, and such failure could substantially decrease or delay market acceptance and sales of our present and future products, which would significantly harm our business, financial condition, and results of operations. Even if we are able to anticipate, develop, and commercially introduce new products and enhancements, there can be no assurance that new products or enhancements will achieve widespread market acceptance.

For example, in connection with the acquisitions of Altor and Trapeze in 2010, we are now offering a virtualization security product and a WLAN product. Additionally, in 2011, we announced our new data center product, the QFabric™ solution, our mobility solutions with our MobileNext^TM software and our Converged Supercore product, which converges the optical and packet layers of the network. If these or other new products do not gain market acceptance at a sufficient rate of growth, our ability to meet future financial targets may be adversely affected. In addition, if we fail to achieve market acceptance at a sufficient rate of growth, our ability to meet future financial targets and aspirations may be adversely affected. Finally, if we fail to deliver new or announced products to the market in a timely manner, it could adversely affect the market acceptance of those products and harm our competitive position and our business and financial results.

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

Our future success depends upon our ability to recruit and retain the services of executive, engineering, sales and marketing, and support personnel. The supply of highly qualified individuals, in particular engineers in very specialized technical areas, or sales people specializing in the service provider and enterprise markets, is limited and competition for such individuals is intense. None of our officers or key employees is bound by an employment agreement for any specific term. The loss of the services of any of our key employees, the inability to attract or retain personnel in the future or delays in hiring required personnel, particularly engineers and sales people, and the complexity and time involved in replacing or training new employees, could delay the development and introduction of new products, and negatively impact our ability to market, sell, or support our products.

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

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

From time to time, we receive preliminary notices of deficiency or notices of proposed adjustments from the IRS claiming that we owe additional taxes, plus interest and possible penalties. For example, we received a preliminary notice of deficiency in 2011 and one in 2009 for prior tax years based on transfer pricing transactions related to the license of acquired intangibles under an intercompany R&D cost sharing arrangement. As a result of the preliminary notices of deficiency received in 2011 and 2009, the incremental tax liability would be approximately $92.0 million and $807.0 million, excluding interest and penalties, respectively. We believe the IRS' position with regard to these matters is inconsistent with applicable tax laws, judicial precedent and existing Treasury regulations, and that our previously reported income tax provisions for the years in question are appropriate. However, there can be no assurance that these matters will be resolved in our favor. Regardless of whether these matters are resolved in our favor, the final resolution of these matters could be expensive and time-consuming to defend and/or settle. While we believe we have provided adequately for these matters, there is a possibility that an adverse outcome of these matters individually or in the aggregate could have a material effect on our results of operations and financial condition.

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

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

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

We depend on independent contract manufacturers (each of which is a third-party manufacturer for numerous companies) to manufacture our products. Although we have contracts with our contract manufacturers, these contracts do not require them to manufacture our products on a long-term basis in any specific quantity or at any specific price. In addition, it is time-consuming and costly to qualify and implement additional contract manufacturer relationships. Therefore, if we fail to effectively manage our contract manufacturer relationships, or if one or more of them experiences delays, disruptions, or quality control problems in our manufacturing operations, or if we had to change or add additional contract manufacturers or contract manufacturing sites, our ability to ship products to our customers could be delayed. Also, the addition of manufacturing locations or contract manufacturers would increase the complexity of our supply chain management. Moreover, an increasing portion of our manufacturing is performed in China and other countries and is therefore subject to risks associated with doing business in other countries. Each of these factors could adversely affect our business, financial condition, and results of operations.

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

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

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

We, and certain of our current and former officers and current and former members of our Board of Directors, are subject to various lawsuits. We have been served with lawsuits related to employment matters, commercial transactions and patent infringement as well as securities laws, a description of the securities lawsuits can be found in Note 15, Commitments and Contingencies, in Notes to Consolidated Financial Statements of this Quarterly Report on Form 10-Q, under the heading “Legal Proceedings.” There can be no assurance that these or any actions that have been or may in the future be brought against us, our officers, and our directors will be resolved favorably or that tentative settlements will become final. Regardless of whether they are resolved, these lawsuits are, and any future lawsuits or threatened legal proceedings to which we, our officers, or our directors may become a party will likely be, expensive and time-consuming to defend, settle, and/or resolve. Legal proceedings, threatened legal proceedings or investigations, regardless of their ultimate outcome, could harm our reputation. Costs of defense, as well as any losses resulting from these claims or settlement of these claims, could significantly increase

Table of Contents

our expenses and could harm our business, financial condition, and results of operations.

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

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

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

Our ability to successfully offer our products and services in a rapidly evolving market requires an effective planning, forecasting, and management process to enable us to effectively scale and adjust our business in response to fluctuating market opportunities and conditions. In periods of market expansion, we have increased investment in our business by, for example, increasing headcount and increasing our investment in R&D, sales and marketing, and other parts of our business as we have in the 2011 fiscal year and in the first quarter of 2012. Conversely, during 2009, in response to downward trending industry and market conditions, we restructured our business, rebalanced our workforce, and reduced our real estate portfolio. Many of our expenses, such as real estate expenses, cannot be rapidly or easily adjusted because of fluctuations in our business or numbers of employees. Moreover, rapid changes in the size of our workforce could adversely affect our ability to develop and deliver products and services as planned or impair our ability to realize our current or future business objectives.

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

We derive a majority of our revenues from our international operations, and we plan to continue expanding our business in international markets in the future. We conduct significant sales and customer support operations directly and indirectly through our distributors and value-added resellers in countries throughout the world and depend on the operations of our contract manufacturers and suppliers that are located outside of the United States. In addition, a portion of our R&D and our general and administrative operations are conducted outside the United States. In some countries, we may experience reduced intellectual property protection.

As a result of our international operations, we are affected by economic, regulatory, social, and political conditions in foreign countries, including changes in general IT spending, the imposition of government controls, including critical infrastructure protection, changes or limitations in trade protection laws, other regulatory requirements, which may affect our ability to import or export our products from various countries, service provider and government spending patterns affected by political considerations, unfavorable changes in tax treaties or laws, natural disasters, epidemic disease, labor unrest, earnings expatriation restrictions, misappropriation of intellectual property, military actions, acts of terrorism, political and social unrest and difficulties in staffing and managing international operations. Any or all of these factors could have a material adverse impact on our business, financial condition, and results of operations.

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

Table of Contents

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

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

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

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

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

We have made, and may continue to make, acquisitions in order to enhance our business. For example, in February 2012, we acquired Mykonos, and in 2010 we acquired Altor, Trapeze, SMobile, and Ankeena. Acquisitions involve numerous risks, including problems combining the purchased operations, technologies or products, unanticipated costs, diversion of management's attention from our core businesses, adverse effects on existing business relationships with suppliers and customers, risks associated with entering markets in which we have no or limited prior experience, and potential loss of key employees. There can be no assurance that we will be able to integrate successfully any businesses, products, technologies, or personnel that we might acquire. The integration of businesses that we may acquire is likely to be a complex, time-consuming, and expensive process and we may not realize the anticipated revenues or other benefits associated with our acquisitions if we fail to successfully manage and operate the acquired business. If we fail in any acquisition integration efforts and are unable to efficiently operate as a combined organization utilizing common information and communication systems, operating procedures, financial controls, and human resources practices, our business, financial condition, and results of operations may be adversely affected.

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

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

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

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

We are required to test annually and review on an interim basis, our goodwill and intangible assets with indefinite lives, including the goodwill associated with past acquisitions and any future acquisitions, to determine if impairment has occurred. As of March 31, 2012, our goodwill was $3,987.7 million. If such assets are deemed impaired, an impairment loss equal to the amount by which the carrying amount exceeds the fair value of the assets would be recognized. This would result in

Table of Contents

incremental expenses for that quarter, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred. For example, such impairment could occur if the market value of our common stock falls below certain levels for a sustained period, or if the portions of our business related to companies we have acquired fail to grow at expected rates or decline. In the second quarter of 2006, our impairment evaluation resulted in a reduction of $1,280.0 million to the carrying value of goodwill on our balance sheet for the SLT operating segment, primarily due to the decline in our market capitalization that occurred over a period of approximately nine months prior to the impairment review and, to a lesser extent, a decrease in forecasted future cash flows. In recent years, economic weakness contributed to extreme price and volume fluctuations in global stock markets that reduced the market price of many technology company stocks, including ours. Future declines in our stock price, as well as any marked decline in our level of revenues or gross margins, increase the risk that goodwill and intangible assets may become impaired in future periods. We cannot accurately predict the amount and timing of any impairment of assets.

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

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

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

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

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

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

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

Table of Contents

adversely affected.

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

While we believe that we currently have adequate internal control over financial reporting, we are exposed to risks from legislation requiring companies to evaluate those internal controls.

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

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

At March 31, 2012, we had $2,913.1 million in cash and cash equivalents and $1,302.7 million in short- and long-term investments. We have invested these amounts primarily in U.S. government securities, government-sponsored enterprise obligations, foreign government debt securities, corporate notes and bonds, commercial paper, and money market funds meeting certain criteria. Certain of these investments are subject to general credit, liquidity, market, and interest rate risks, which may be exacerbated by U.S. sub-prime mortgage defaults that have affected various sectors of the financial markets and caused credit and liquidity issues at many financial institutions. Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of our publicly traded debt or equity investments is judged to be other-than-temporary. These market risks associated with our investment portfolio may have a negative adverse effect on our liquidity, financial condition, and results of operations.

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

In March 2011, we issued senior unsecured notes for an aggregate principle amount of $1.0 billion (see discussion in Note 10, Long-Term Debt and Financing, in the Notes to Condensed Consolidated Financial Statements). We may not be able to generate sufficient cash flow to enable us to service our indebtedness, including the notes, or to make anticipated capital expenditures. Our ability to pay our expenses and satisfy our debt obligations, refinance our debt obligations and fund planned capital expenditures will depend on our future performance, which will be affected by general economic, financial, competitive, legislative, regulatory and other factors beyond our control. Based upon current levels of operations, we believe cash flow from operations and available cash will be adequate for the foreseeable future to meet our anticipated requirements for working capital, capital expenditures and scheduled payments of principal and interest on our indebtedness, including the senior notes. However, if we are unable to generate sufficient cash flow from operations or to borrow sufficient funds in the future to service our debt, we may be required to sell assets, reduce capital expenditures, refinance all or a portion of our existing debt (including the senior notes) or obtain additional financing. There is no assurance that we will be able to refinance our debt, sell assets or borrow more money on terms acceptable to us, or at all.

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


•	incur liens;


•	incur sale and leaseback transactions; and

Table of Contents


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

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

Uninsured losses could harm our operating results.

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

(1)

Shares were repurchased under the stock repurchase program approved by the Board in February 2010 (the “2010 Stock Repurchase Program”), which authorized the Company to purchase up to an additional $1.0 billion of the Company's common stock. Future share repurchases under the Company's 2010 Stock Repurchase Program will be subject to a review of the circumstances in place at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. This program may be discontinued at any time. As of March 31, 2012, the 2010 Stock Repurchase Program had $162,225,622 remaining authorized funds available for future stock repurchases.

(2)

Amounts include repurchases under the Company's stock repurchase program and repurchases of the Company's common stock from its employees in connection with net issuance of shares to satisfy the employee tax withholding obligations for the vesting of certain restricted stock units and performance share awards. We repurchased an immaterial amount of shares of common stock from our employees in connection with net issuances during the three months ended March 31, 2012. All shares of common stock that have been repurchased under the Company's stock repurchase programs and from its employees in connection with net issuances have been retired.
