Note 1. Basis of Presentation

Basis of Presentation

The unaudited Condensed Consolidated Financial Statements of Juniper Networks, Inc. (the “Company” or “Juniper”) have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of March 31, 2016 , is derived from the audited Consolidated Financial Statements for the year ended December 31, 2015 . 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, 2016 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2016 , or any future period. The information included in this Quarterly Report on Form 10-Q (“Report”) should be read in conjunction with “Management's Discussion and Analysis of Financial Condition and Results of Operations,” “Risk Factors,” “Quantitative and Qualitative Disclosures About Market Risk,” and the Consolidated Financial Statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015 . Certain amounts in the prior-year Financial Statements contained in this Report have been reclassified to conform to the current-year presentation, including the adoption of Accounting Standards Update ("ASU") No. 2015-03 (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"), which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company has retrospectively adopted this standard effective January 1, 2016, resulting in a $11.3 million decrease in both other long-term assets and long-term debt as of December 31, 2015 on the Condensed Consolidated Balance Sheets. The adoption of ASU No. 2015-03 had no impact to the Company’s Condensed Consolidated Statements of Operations.

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

Note 2. Summary of Significant Accounting Policies

There have been no material changes to the Company's significant accounting policies compared to the accounting policies described in Note 2, Significant Accounting Policies , in Notes to Consolidated Financial Statements in Item 8 of Part II of the Annual Report on Form 10-K for the year ended December 31, 2015 .

Recent Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-09 (Topic 718) Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"), which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, forfeiture, statutory tax withholding requirements, and classification on the statement of cash flows. ASU-2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its Consolidated Financial Statements and disclosures.

In March 2016, the FASB issued ASU No. 2016-07 (Topic 323) Investments—Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting ("ASU 2016-07"), which eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. This update requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. This update requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes

qualified for use of the equity method. ASU 2016-07 is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its Consolidated Financial Statements and disclosures.

In March 2016, the FASB issued ASU No. 2016-06 (Topic 815) Derivatives and Hedging: Contingent Put and Call Options in Debt Instruments ("ASU 2016-06"), which requires that embedded derivatives be separated from the host contract and accounted for separately as derivatives if certain criteria are met. One of those criteria is that the economic characteristics and risks of the embedded derivatives are not clearly and closely related to the economic characteristics and risks of the host contract (the “clearly and closely related” criterion). In addition, in March 2016, the FASB issued ASU No. 2016-05 (Topic 815), Derivatives and Hedging: Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships, ("ASU 2016-05"), which clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-06 and ASU 2016-05 are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its Consolidated Financial Statements and disclosures.

In February 2016, the FASB issued ASU No. 2016-02 (Topic 842), Leases ("ASU 2016-02"), which requires recognition of lease assets and lease liabilities on the balance sheet by the lessees for lease contracts with a lease term of more than twelve months. ASU 2016-02 should be applied on a modified retrospective basis and is effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its Consolidated Financial Statements and disclosures.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"), which requires equity investments to be measured at fair value with changes in fair value recognized in net income and simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. Entities may choose a practical expedient, to estimate the fair value of certain equity securities that do not have readily determinable fair value. If the practical expedient is elected, these investments would be recorded at cost, less impairment and subsequently adjusted for observable price changes. The guidance also updates certain presentation and disclosure requirements. ASU 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is not permitted. The Company is currently evaluating the impact that ASU 2016-01will have on its Consolidated Financial Statements and disclosures.

In July 2015, the FASB issued ASU No. 2015-11 (Subtopic 330) - Simplifying the Measurement of Inventory ("ASU 2015-11"), which provides guidance to companies who account for inventory using either the first-in, first-out ("FIFO") or average cost methods. The guidance states that companies should measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016. Early adoption is permitted. The adoption of this standard will not have a significant impact on the Company's Consolidated Financial Statements.

In May 2014, the FASB issued ASU No. 2014-09 (Topic 606) —Revenue from Contracts with Customers (“ASU 2014-09”) which provides guidance for revenue recognition. This ASU affects all contracts that the Company enters into with customers to transfer goods and services or for the transfer of nonfinancial assets. This ASU will supersede the revenue recognition requirements in Topic 605, and most industry specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The standard's core principle is that revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. In doing so, the Company will need to use additional judgment and estimates than under the existing guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of the new revenue standard from December 15, 2016 to December 15, 2017, with early adoption permitted as of annual reporting periods beginning after December 15, 2016. Accordingly, the ASU will be effective for the Company beginning fiscal year 2018. In addition, in March 2016, the FASB issued ASU No. 2016-08 (Topic 606) Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”) , which clarifies the principal-versus-agent guidance in Topic 606 and requires an entity to determine whether the nature of its promise to provide goods or services to a customer is performed in a

principal or agent capacity and to recognize revenue in a gross or net manner based on its principal/agent designation. In April 2016, the FASB also issued ASU No. 2016-10 (Topic 606) Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing (“ASU 2016-10”), which amends the revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. There are two transition methods available under the new standard, either cumulative effect or retrospective. ASU 2016-08 and ASU 2016-10 must be adopted concurrently with the adoption of ASU 2014-09. The Company is currently evaluating the impact of the adoption of this standard on its Consolidated Financial Statements and disclosures.

The Company had 348 and 682 investments in unrealized loss positions as of March 31, 2016 and December 31, 2015 , respectively. The gross unrealized losses related to these investments were primarily due to changes in market interest rates and stock prices. The Company periodically reviews its investments to identify and evaluate investments that have an indication of possible impairment. The Company aggregates its investments by category and length of time the securities have been in a continuous unrealized loss position to facilitate its evaluation.

For available-for-sale debt securities that have unrealized losses, the Company evaluates whether (i) it has the intention to sell any of these investments and (ii) whether it is more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. As of March 31, 2016 , the Company anticipates that it will recover the entire amortized cost basis of such available-for-sale debt securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the three months ended March 31, 2016 and March 31, 2015 .

For available-for-sale equity securities that have unrealized losses, the Company evaluates whether there is an indication of other-than-temporary impairments. This determination is based on several factors, including the financial condition and near-term prospects of the issuer and the Company's intent and ability to hold the publicly-traded equity securities for a period of time sufficient to allow for any anticipated recovery in market value. During the three months ended March 31, 2016 and March 31, 2015 , the Company did not recognize other-than-temporary impairments associated with these investments.

During the three months ended March 31, 2016 and March 31, 2015 , there were no material gross realized gains or losses from available-for-sale securities and there were no material gross realized gains or losses from trading securities.

Restricted Cash and Investments

The Company classifies certain cash and investments as restricted cash and investments on its Condensed Consolidated Balance Sheets for: (i) amounts held in escrow accounts, as required in connection with certain acquisitions completed between 2005 and 2014; (ii) the India Gratuity Trust and Israel Retirement Trust, which cover statutory severance obligations in the event of termination of any of the Company's India and Israel employees, respectively; and (iii) the Directors and Officers indemnification trust (“D&O Trust”). The restricted investments are designated as available-for-sale securities.

Privately-Held Investments

The Company has privately-held investments, which include debt and redeemable preferred stock securities that are carried at fair value, and non-redeemable preferred stock securities that are carried at cost.

As of March 31, 2016 and December 31, 2015 , the carrying values of the Company's privately-held investments of $107.8 million and $102.4 million , respectively, were included in other long-term assets in the Condensed Consolidated Balance Sheets. As of March 31, 2016 and December 31, 2015 , the carrying value of the privately-held investments includes debt and redeemable preferred stock securities of $68.6 million and $60.2 million , respectively. For the three months ended March 31, 2016 and March 31, 2015 , there were no unrealized gains or losses associated with the privately-held debt and redeemable preferred stock securities.

The Company reviews its investments to identify and evaluate investments that have an indication of possible impairment. During the three months ended March 31, 2016 , the Company determined that certain privately-held investments were other-than-temporarily impaired, resulting in impairment charges of $5.1 million that were recorded within other expense, net in the Condensed Consolidated Statement of Operations. No such charges were recorded during the three months ended March 31, 2015 .

The Company's Level 2 available-for-sale fixed income securities are priced using quoted market prices for similar instruments or non-binding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, or alternative pricing sources with reasonable levels of price transparency which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets. The Company's derivative instruments are classified as Level 2, as they are not actively traded and are valued using pricing models that use observable market inputs. The Company's policy is to recognize asset or liability transfers among Level 1, Level 2, and Level 3 at the beginning of the quarter in which a change in circumstances resulted in a transfer. During the three months ended March 31, 2016 , the Company had no transfers between levels of the fair value hierarchy of its assets or liabilities measured at fair value.

All of the Company's privately-held debt and redeemable preferred stock securities, are classified as Level 3 assets due to the absence of quoted market prices and an inherent lack of liquidity. The Company estimates the fair value of its privately-held debt investments on a recurring basis using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities and the investee's capital structure. During the three months ended March 31, 2016 , there were purchases related to privately-held debt securities of $10.5 million .

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain of the Company's assets, including intangible assets, goodwill, and privately-held equity investments, are measured at fair value on a nonrecurring basis, only if impairment is indicated. Privately-held equity investments, which are normally carried at cost, are measured at fair value on a nonrecurring basis due to events and circumstances that the Company identifies as significantly impacting the fair value of investments. The Company estimates 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 and the investee's capital structure. Purchased intangible assets are measured at fair value primarily using discounted cash flow projections.

As of March 31, 2016 , certain privately-held equity investments with a carrying value of $5.1 million , were impaired and were written-down to their fair value of zero and were classified as Level 3 assets due to the absence of quoted market prices and inherent lack of liquidity. The impairment charges of $5.1 million were recorded to other expense, net in the Condensed Consolidated Statements of Operations. As of  December 31, 2015 , the Company had no significant privately-held equity investments measured at fair value on a nonrecurring basis. 

As of  March 31, 2016  and  December 31, 2015 , the Company had no liabilities measured at fair value on a nonrecurring basis.

Assets and Liabilities Not Measured at Fair Value

The carrying amounts of the Company's accounts receivable, financing receivables, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. As of March 31, 2016 and December 31, 2015 , the estimated fair value of the Company's long-term debt in the Condensed Consolidated Balance Sheets was approximately $2,165.8 million and $1,946.7 million , respectively, based on observable market inputs (Level 2). The carrying value of the promissory note, issued to the Company in connection with the sale of Junos Pulse, of $132.9 million approximates its fair value and is recorded in other long-term assets in the Condensed Consolidated Balance Sheets as of March 31, 2016 and December 31, 2015 , respectively. The promissory note is classified as a Level 3 asset due to the absence of quoted market prices and inherent lack of liquidity. See Note 7, Other Financial Information , for further information on the promissory note.

Note 5. 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 the Company's foreign currency derivatives are summarized as follows (in millions):

								
 	As of	
 	March 31,
2016	 	December 31,
2015	
Cash flow hedges	$	125.6		 	$	116.8		
Non-designated derivatives	21.3		 	71.8		
     Total	$	146.9		 	$	188.6		

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 hedge the U.S. Dollar equivalent of the Company's planned cost of services and operating expenses denominated in certain foreign currencies. These derivatives are designated as cash flow hedges. Execution of these cash flow hedge derivatives typically occurs every month with maturities of one year or less. The effective portion of the derivative's gain or loss is initially reported as a component of accumulated other comprehensive loss, and upon occurrence of the forecasted transaction, is subsequently reclassified into the cost of services or operating expense line item to which the hedged transaction relates. The Company records any ineffectiveness of the hedging instruments in other expense, net, on its Condensed Consolidated Statements of Operations. Cash flows from such hedges are classified as operating activities. All amounts within other comprehensive income are expected to be reclassified into earnings within the next twelve months.

See Note 4, Fair Value Measurements , for the fair values of the Company's derivative instruments in the Condensed Consolidated Balance Sheets.

As of March 31, 2016 , the Company recognized unrealized gains of $3.0 million in accumulated other comprehensive loss for the effective portion of its derivative instruments and reclassified a realized loss during the three months ended March 31, 2016 of $1.3 million from other comprehensive loss to cost of revenues and operating expense in the Condensed Consolidated Statements of Operations. As of March 31, 2015 , the Company recognized an unrealized loss of $6.1 million in accumulated other comprehensive loss for the effective portion of its derivative instruments and reclassified a realized loss of $3.0 million during the three months ended March 31, 2016 from other comprehensive loss to cost of revenues and operating expense in the Condensed Consolidated Statements of Operations.

The ineffective portion of the Company's derivative instruments recognized in its Condensed Consolidated Statements of Operations was not material during the three months ended March 31, 2016 and March 31, 2015 .

Non-Designated Derivatives

The Company also uses foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. These derivatives are carried at fair value with changes recorded in other expense, net, in the Condensed Consolidated Statements of Operations. Changes in the fair value of these derivatives are largely offset by remeasurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. These foreign exchange forward contracts have maturities within two months.

During the three months ended March 31, 2016 and March 31, 2015 , the Company recognized a net loss of $1.3 million and a net gain of $2.1 million , respectively, on non-designated derivative instruments within other expense, net, in its Condensed Consolidated Statements of Operations.

Offsetting of Derivatives

The Company presents its derivative assets and derivative liabilities on a gross basis in the Condensed Consolidated Balance Sheets. However, under agreements containing provisions on netting with certain counterparties of foreign exchange contracts, subject to applicable requirements, the Company is allowed to net-settle transactions on the same date in the same currency, with a single net amount payable by one party to the other. As of March 31, 2016 and December 31, 2015 , the potential effect of rights of setoff associated with derivative instruments was not material. The Company is neither required to pledge nor entitled to receive cash collateral related to these derivative transactions.

Note 6. Goodwill and Purchased Intangible Assets

 ________________________________
		
(*)  	During the three months ended March 31, 2016, the Company adopted ASU 2015-03. The balance as of December 31, 2015 was retrospectively adjusted to conform to the current-year presentation.	
On October 1, 2014, the Company completed the sale of its Junos Pulse product portfolio. The Company received total consideration of $230.7 million , of which $105.7 million was in cash, net of a $19.3 million working capital adjustment, and $125.0 million was in the form of a non-contingent interest-bearing promissory note due to the Company on April 1, 2016 (the “Pulse Note”). On October 2, 2015, the Company and the issuer of the Pulse Note mutually agreed to amend the original terms of the Pulse Note to, among other things, extend the maturity date from April 1, 2016 to December 31, 2018, provided that interest due on the Pulse Note through December 31, 2015 shall be paid in kind by increasing the outstanding principal amount of the note and increasing the interest rate on the Pulse Note. In addition, under the amended terms of the Pulse Note, the issuer is required to make a minimum payment of $75.0 million on or prior to April 1, 2017, less any amount previously pre-paid to the Company. The note receivable, along with interest paid in kind, is classified as long-term assets based on expected collection beyond twelve months from the Condensed Consolidated Balance Sheet date.

The Company considers notes receivable to be impaired when, based on current information and events, it is probable that the Company will not be able to collect the scheduled payments of principal or interest when due. Further, the Company measures any impairment to the Pulse Note based on the present value of expected cash flows, which are discounted at the note's effective interest rate, compared to the recorded investment of the note, including principal and accrued interest. Based on the impairment assessment, no impairment charge was required to the Pulse Note as of March 31, 2016 . Interest income on the Pulse Note is accrued and credited to interest income as it is earned, unless it is not probable the Company will collect the amounts due or if the present value of expected cash flows is less than the recorded investment. During the three months ended March 31, 2016 and March 31, 2015 , the related amount of interest income recognized was $2.7 million and $1.6 million , respectively.

Warranties

The Company accrues for warranty costs based on associated material, labor for customer support, and overhead at the time revenue is recognized. This accrual is reported within other accrued liabilities in the Condensed Consolidated Balance Sheets. Changes in the Company’s warranty reserve during the three months ended March 31, 2016 were as follows (in millions):

				
Balance as of December 31, 2015	$	28.4		
Provisions made during the period	6.6		
Actual costs incurred during the period	(6.6	)	
Balance as of March 31, 2016	$	28.4

Long-term	366.7		 	345.2		
Total	$	1,260.0		 	$	1,168.1		

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

Other Expense, Net

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

								
 	Three Months Ended March 31,	
 	2016	 	2015	
Interest income	$	7.9		 	$	3.8

In March 2015, the Company issued $300.0 million aggregate principal amount of 3.30% senior notes due 2020 ("2020 Notes") and $300.0 million aggregate principal amount of 4.35% senior notes due 2025 ("2025 Notes"). In addition, in March 2014, the Company issued $350.0 million aggregate principal amount of the 2024 Notes, which form a single series and are fully fungible with the 2024 Notes issued in February 2016.

The "2019 Notes", "2020 Notes," "2021 Notes," "2024 Notes", "2025 Notes" and "2041 Notes" collectively the "Notes" are the Company’s senior unsecured and unsubordinated obligations, ranking equally in right of payment to all of the Company’s existing and future senior unsecured and unsubordinated indebtedness and senior in right of payment to any of the Company’s future indebtedness that is expressly subordinated to the Notes.

The Company may redeem the 2020 Notes and 2025 Notes, either in whole or in part, at any time one month prior to the maturity date of the 2020 Notes, and three months prior to the maturity date of the 2025 Notes, at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the 2020 Notes and 2025 Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments discounted at the Treasury rate plus 30 basis points for the 2020 Notes, or the Treasury rate plus 37.5 basis points for the 2025 Notes, plus, in the case of each of the clauses (i) and (ii) above, accrued and unpaid interest, if any. At any time on or after May 15, 2020, in the case of the 2020 Notes, and at any time on or after March 15, 2025, in the case of the 2025 Notes, the Company may redeem Notes of such series, in whole or in part, at a redemption price equal to 100% of the principal amount of the 2020 Notes and the 2025 Notes to be redeemed, plus accrued and unpaid interest, if any. The Company may redeem the other Notes, either in whole or in part, at any time at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments discounted to the redemption date, plus, in either case, accrued and unpaid interest, if any.

In the event of a change of control repurchase event, the holders of the Notes may require the Company to repurchase for cash all or part of the Notes at a purchase price equal to 101% of the aggregate principal amount, plus accrued and unpaid interest, if any.

Interest on the Notes is payable in cash semiannually. The effective interest rates for the Notes include the interest on the Notes, accretion of the discount, and amortization of issuance costs. The indentures that govern the Notes also contain various covenants, including limitations on the Company's ability to incur liens or enter into sale-leaseback transactions over certain dollar thresholds.

In March 2016, the Company repaid the aggregate principal amount of $300.0 million on its 3.10% senior notes upon maturity.

As of March 31, 2016 , the Company was in compliance with all covenants in the indentures governing the Notes.

Revolving Credit Facility

On June 27, 2014, the Company entered into a Credit Agreement (“Credit Agreement”) with certain institutional lenders and Citibank, N.A., as administrative agent, that provides for a $500.0 million unsecured revolving credit facility, with an option of the Company to increase the amount of the credit facility by up to an additional $200.0 million , subject to certain conditions. Proceeds of loans made under the Credit Agreement may be used by the Company for working capital and general corporate purposes. Revolving loans may be borrowed, repaid and reborrowed until June 27, 2019, at which time all amounts borrowed must be repaid. Borrowing may be denominated, at the Company's option, in U.S. dollars, Pounds Sterling or Euro.

Borrowings under the Credit Agreement will bear interest at either i) a floating rate per annum equal to the base rate plus a margin of between 0.00% and 0.50% , depending on the Company's public debt rating or ii) a per annum rate equal to the reserve adjusted Eurocurrency rate , plus a margin of between 0.90% and 1.50% , depending on the Company's public debt rating. Base rate is defined as the greatest of (A)  Citibank's base rate , (B) the Federal Funds rate plus 0.50% or (C) the ICE Benchmark Administration Settlement Rate applicable to dollars for a period of one month plus 1.00% . The Eurocurrency rate is determined for U.S. dollars and Pounds Sterling as the rate at which deposits in such currency are offered in the London interbank market for the applicable interest period and for Euro as the rate specified for deposits in Euro with a maturity comparable to the applicable interest period.

As of March 31, 2016 , the Company was in compliance with all covenants in the Credit Agreement, and no amounts were outstanding.

Customer Financing Arrangements

The Company provides certain distribution partners access to extended financing arrangements for certain end-user customers that require longer payment terms than those typically provided by the Company through factoring accounts receivable to third-party financing providers (“financing providers”). The program does not and is not intended to affect the timing of the Company's revenue recognition. Under the financing arrangements, proceeds from the financing provider are due to the Company within 30 to 90 days from the sale of the receivable. In these transactions with the financing provider, the Company surrenders control over the transferred assets. Beginning in 2014 and through 2015, the Company transitioned certain distribution partners from the third party financing program to the Company's commercial payment terms. As a result, the Company's customer financing activities significantly declined from fiscal year 2014 through the first quarter of 2016.

Pursuant to the financing arrangements for the sale of receivables, the Company sold net receivables of $4.9 million and $47.1 million during the three months ended March 31, 2016 and March 31, 2015 , respectively.

The Company received cash proceeds from the financing provider of $1.7 million and $60.0 million during the three months ended March 31, 2016 and March 31, 2015 , respectively. As of March 31, 2016 and December 31, 2015 , the amounts owed by the financing provider were $4.4 million and $1.2 million , respectively, and were recorded in accounts receivable on the Condensed Consolidated Balance Sheets.

Stock Repurchase Activities

In February 2014, the Company's Board approved a stock repurchase program that authorized the Company to repurchase up to $2.1 billion of its common stock, including $1.2 billion pursuant to an accelerated share repurchase program (“2014 Stock Repurchase Program”). In October 2014 and July 2015, the Board authorized a $1.3 billion and $500.0 million increase, respectively, to the 2014 Stock Repurchase Program for a total of $3.9 billion . As of March 31, 2016 , there was $457.5 million of authorized funds remaining under the 2014 Stock Repurchase Program.

During the three months ended March 31, 2016 and March 31, 2015 , the Company repurchased and retired approximately 3.1 million and 17.4 million shares of its common stock, respectively, at an average price of $23.89 and $23.05 per share, respectively, for an aggregate purchase price of $75.0 million and $400.0 million , respectively.

In addition to repurchases under the Company’s stock repurchase program, the Company also repurchases common stock from certain employees in connection with the net issuance of shares to satisfy minimum tax withholding obligations upon the vesting of certain stock awards issued to such employees. Repurchases associated with tax withholdings were not significant during the three months ended March 31, 2016 and March 31, 2015 .

Future share repurchases under the Company’s stock repurchase programs will be subject to a review of the circumstances 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.

The Company's stock repurchase programs may be discontinued at any time. See Note 15, Subsequent Events, for discussion of the Company's stock repurchase activity subsequent to March 31, 2016 .

Note 10. Employee Benefit Plans

Equity Incentive Plans

The Company’s equity incentive plans include the 2015 Equity Incentive Plan (the “2015 Plan”), the 2006 Equity Incentive Plan (the “2006 Plan”), the Amended and Restated 1996 Stock Plan (the “1996 Plan”), various equity incentive plans assumed through acquisitions, and the 2008 Employee Stock Purchase Plan (the “ESPP”). Under these plans, the Company has granted (or, in the case of acquired plans, assumed) stock options, restricted stock units (“RSUs”), restricted stock awards (“RSAs”), and performance share awards (“PSAs”).

The 2015 Plan was adopted and approved by the Company's stockholders in May 2015 and had an initial authorized share reserve of 38.0 million shares of common stock plus the addition of any shares subject to outstanding awards under the 2006 Plan and the 1996 Plan that were outstanding as of May 19, 2015, and that subsequently expire or otherwise terminate, up to a maximum of an additional 29.0 million shares. As of March 31, 2016 , an aggregate of 22.1 million shares were subject to outstanding equity awards under the 2015 Plan and the 2006 Plan, and no shares were subject to outstanding equity awards under the 1996 Plan. As of March 31, 2016 , 23.6 million shares were available for future issuance under the 2015 Plan and no shares were available for future issuance under the 2006 Plan or the 1996 Plan.

The ESPP was adopted and approved by the Company's stockholders in May 2008. To date, the Company's stockholders have approved a share reserve of 26.0 million shares of the Company's common stock for issuance under this plan, which includes an additional 7.0 million shares approved by the Company's stockholders in May 2015. The ESPP permits eligible employees to acquire shares of the Company’s common stock at a 15% discount to the offering price (as determined in the ESPP) through periodic payroll deductions of up to 10% of base compensation, subject to individual purchase limits of 6,000 shares in any twelve -month period or $25,000 worth of stock, determined at the fair market value of the shares at the time the stock purchase option is granted, in one calendar year. As of March 31, 2016 , approximately 19.7 million shares have been issued and 6.3 million shares remain available for future issuance under the ESPP.

In connection with certain past acquisitions, the Company assumed stock options, RSUs, and RSAs under the assumed stock plans of the acquired companies and exchanged the assumed awards for the Company's stock options, RSUs, and RSAs, respectively. No new equity awards can be granted under these assumed plans. As of March 31, 2016 , stock options, RSUs, and RSAs representing approximately 1.0 million shares of common stock were outstanding under all awards assumed through the Company's acquisitions.

On January 27, 2016, the Company declared a cash dividend of $0.10 per share of common stock, or $38.3 million in the aggregate, to stockholders of record on March 1, 2016, which was paid on March 22, 2016.	

Employee Stock Purchase Plan

The ESPP is implemented in a series of offering periods, each currently six months in duration, or such other period as determined by the Board. Employees purchased 1.3 million and 1.4 million shares of common stock through the ESPP at an average exercise price of $20.06 and $19.32 per share for the three months ended March 31, 2016 and March 31, 2015 , respectively.

Valuation Assumptions

The weighted-average assumptions used and the resulting estimates of fair value for ESPP and market-based RSUs during the three months ended March 31, 2016 and March 31, 2015 were as follows:

				
 	Three Months Ended March 31,	
 	2016	 	2015	
ESPP (1) :	 	 	 	
Volatility	35%	 	30%	
Risk-free interest rate	0.5%	 	0.1%	
Expected life (years)	0.5	 	0.5	
Dividend yield	1.7%	 	1.9%	
Weighted-average fair value per share	$5.95	 	$5.23	
 	 	 	 	
Market-based RSUs (2) :	 	 	 	
Volatility	36%	 	34%	
Risk-free interest rate	1.2%	 	1.4%	
Dividend yield	1.7%	 	1.8%	
Weighted-average fair value per share	$14.71	 	$14.97	
________________________________
		
(1)  	The Black-Scholes-Merton option-pricing model is utilized to estimate the fair value of shares issuable under the ESPP.	
		
(2)  	The fair value of market-based RSUs utilizes a Monte Carlo valuation methodology. The Company amortizes the fair value of these awards over the derived service period adjusted for estimated forfeitures for each separately vesting tranche of the award. Provided that the derived service is rendered, the total fair value of the market-based RSUs at the date of grant is recognized as compensation expense even if the market condition is not achieved. However, the number of shares that ultimately vest can vary significantly with the performance of the specified market criteria.

Note 11. Segments

The Company conducts business globally and is managed, operated and organized by major functional departments that operate on a consolidated basis. Each major functional leader reports directly to the Company's chief executive officer, who is the chief operating decision maker (“CODM”). The Company's CODM views the business, allocates resources and assesses the performance of the Company primarily based on consolidated financial information for the entire business, accompanied by disaggregated information about net revenues by product and service and geographic region as presented below. As a result, the Company operates in one reportable segment.

The following table presents net revenues by product and service (in millions):

								
 	Three Months Ended March 31,	
 	2016	 	2015	
Routing	$	504.1		 	$	504.8		
Switching	175.5		 	166.5		
Security	73.4		 	92.8		
Total product	753.0		 	764.1		
 	 	 	 	
Total service	344.9		 	303.3		
Total	$	1,097.9		 	$	1,067.4		

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

								
 	Three Months Ended March 31,	
 	2016	 	2015	
Americas:	 	 	 	
United States	$	579.0		 	$	533.5

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, 2016 and December 31, 2015 , were attributable to U.S. operations.

Note 12. Income Taxes

The Company's effective tax rates for the three months ended March 31, 2016 and March 31, 2015 of 27.8% and 30.9% , respectively, differ from the federal statutory rate of 35% primarily due to the benefit of the Section 199 deduction for U.S. production activities, earnings in foreign jurisdictions, which are subject to lower tax rates, and the impact of the discrete items noted below. The effective rate for the three months ended March 31, 2015 does not reflect the benefit of the federal research and development (“R&D”) credit, which was permanently reinstated on December 18, 2015 and a change in the tax treatment of share-based compensation in the Company's cost-sharing arrangement, which occurred in the three months ended September 30, 2015.

The effective tax rates for the three months ended March 31, 2016 and March 31, 2015 include the tax benefit of the following discrete items (in millions):

								
 	Three Months Ended March 31,	
 	2016	 	2015	
Loss on privately-held equity investments	$	(1.9	)	 	$	—		
Restructuring charges	$	—		 	$	(1.3	)	

As of March 31, 2016 , the total amount of gross unrecognized tax benefits was $220.8 million , of which $185.8 million , if recognized, would affect the Company's effective tax rate.

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. There is a greater than remote likelihood that the balance of the gross unrecognized tax benefits will decrease by approximately $4.3 million within the next twelve months due to lapses of applicable statutes of limitations and the completion of tax review cycles in various tax jurisdictions.

The Company is currently under examination by the Internal Revenue Service (“IRS”) for the 2007 through 2009 tax years and the California Franchise Tax Board for the 2004 through 2006 tax years. In March 2016, the IRS concluded its field audit and issued a final assessment. The Company is appealing this assessment. As of March 31, 2016, the Company believes the resolution of the audits is unlikely to have a material effect on its consolidated financial condition or results of operations.

The Company is also subject to separate ongoing examinations by the India tax authorities for the 2003 tax year, 2004 through 2008 tax years, and the 2009 through 2011 tax years. As of as of March 31, 2016, the Company is not aware of any other examinations by tax authorities in any other major jurisdictions in which it files income tax returns.

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

The Company is pursuing all available administrative remedies relative to these matters. The Company believes that it has adequately provided for any reasonably foreseeable outcomes related to these proposed adjustments and the ultimate resolution of these matters is unlikely to have a material effect on its consolidated financial condition or results of operations; however there is still a possibility that an adverse outcome of these matters could have a material effect on its consolidated financial condition and results of operations.

Note 13. 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,	
 	2016	 	2015	
Numerator:	 	 	 	
Net income	$	91.4		 	$	80.2		
Denominator:	 	 	 	
Weighted-average shares used to compute basic net income per share	383.2		 	407.1		
Dilutive effect of employee stock awards	6.1		 	7.1		
Weighted-average shares used to compute diluted net income per share	389.3		 	414.2		
Net income per share attributable to Juniper Networks common stockholders:	 	 	 	
Basic	$	0.24		 	$	0.20		
Diluted	$	0.23		 	$	0.19		
 	 	 	 	
Anti-dilutive:	 	 	 	
Potential anti-dilutive shares	4.0		 	6.4		

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

Note 14. Commitments and Contingencies

Commitments

Operating Leases

The Company leases its facilities and certain equipment under non-cancelable operating leases that expire at various dates through March 31, 2026 . Certain leases require the Company to pay variable costs such as taxes, maintenance, and insurance and include renewal options and escalation clauses. Future minimum payments under the non-cancelable operating leases totaled $111.8 million as of March 31, 2016 . Rent expense was $9.1 million and $11.5 million for the three months ended March 31, 2016 and March 31, 2015 , respectively.

Data Center Lease Agreement

On July 10, 2015, the Company entered into a data center lease agreement through March 2026 in which the Company has the option to extend the term of the lease for up to twenty years in increments of either five years or ten years, for approximately 63,000 square feet of space in the State of Washington. The total payment for the lease is expected to be approximately $118.1

million over the ten -year term. The lease agreement provides the Company with a tenant allowance of $6.0 million to be used for tenant leasehold improvements. Any unused tenant allowance may be applied as a credit to the rent payment. The space will be used, among other things, to consolidate certain of the Company's laboratory operations currently located in Sunnyvale, California.

As the Company is subject to certain contractual obligations during the construction period, the Company is deemed the owner of the property during the construction period. Accordingly, as of March 31, 2016 , the Company capitalized the construction cost by recording a build-to-suit lease asset under construction in progress of $59.8 million , which is a component of property and equipment, net, and a corresponding build-to-suit financing liability, which is a component of other long-term liabilities, in the Condensed Consolidated Balance Sheets.

Purchase Commitments with Contract Manufacturers and Suppliers

In order to reduce manufacturing lead times and ensure adequate component supply, the Company enters into agreements with contract manufacturers and certain suppliers to procure inventory based on the Company's requirements. A significant portion of the Company's purchase commitments arising from these agreements consists of firm and non-cancelable commitments. These purchase commitments totaled $601.6 million as of March 31, 2016 .

The Company establishes a liability in connection with purchase commitments related to quantities in excess of its demand forecasts or obsolete materials charges for components purchased by the contract manufacturers based on the Company’s demand forecast or customer orders. As of March 31, 2016 , the Company had accrued $19.8 million based on its estimate of such charges.

Debt and Interest Payment on Debt

As of March 31, 2016 , the Company held long-term debt consisting of the Notes with a carrying value of $2,131.8 million . Of these Notes, $350.0 million will mature in 2019 and bears interest at a fixed rate of 3.125% , $300.0 million will mature in 2020 and bears interest at a fixed rate of 3.30% , $300.0 million will mature in 2021 and bears interest at a fixed rate of 4.60% , $500.0 million will mature in 2024 and bears interest at a fixed rate of 4.50% , $300.0 million will mature in 2025 and bears interest at a fixed rate of 4.35% , and $400.0 million will mature in 2041 and bears interest at a fixed rate of 5.95% . Interest on the Notes is payable semiannually. See Note 8, Debt and Financing , for further discussion of the Company's long-term debt.

Other Contractual Obligations

As of March 31, 2016 , other contractual obligations primarily consisted of (1) $36.1 million in indemnity and employee-related obligations and service-related escrows, including those required in connection with certain asset purchases and acquisitions completed by the Company between 2005 and 2014; (2) $3.5 million in campus build-out obligations; and (3) $45.5 million of agreements that include firm and non-cancelable terms to transfer funds in the future for fixed or minimum amounts or quantities to be purchased at fixed or minimum prices.
Tax Liabilities

As of March 31, 2016 , the Company had $190.4 million included in long-term income taxes payable in the Condensed Consolidated Balance Sheets for unrecognized tax positions. At this time, the Company is unable to make a reasonably reliable estimate of the timing of payments related to this amount due to uncertainties in the timing of tax audit outcomes.

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 solely, or in combination with other third party products, infringe the intellectual property rights of a third-party. As of March 31, 2016 , the Company recorded a $15.6 million liability for such indemnification obligations in other accrued liabilities in the Condensed Consolidated Balance Sheets. The Company also has financial guarantees consisting of guarantees of product and service performance, guarantees related to third-party customer-financing arrangements, custom and duty guarantees, and standby letters of credit for certain lease facilities. As of March 31, 2016 and December 31, 2015 , the Company had $6.1 million and $15.8 million , respectively, in financing arrangements, bank guarantees, and standby letters of credit related to these financial guarantees.

Legal Proceedings

Investigations

The U.S. Securities and Exchange Commission ("SEC") and the U.S. Department of Justice ("DOJ") are conducting investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act ("FCPA"). The Company is cooperating with these agencies regarding these matters. The Company’s Audit Committee, with the assistance of independent advisors, has been investigating and conducting a thorough review of possible violations of the FCPA, and has made recommendations for remedial measures, including employee disciplinary actions in foreign jurisdictions, which the Company has implemented and continues to implement. The Company is unable to predict the duration, scope or outcome of the SEC and DOJ investigations, but believes that an adverse outcome is reasonably possible. However, the Company is not able to estimate a reasonable range of possible loss. The SEC and/or DOJ could take action against the Company or the Company could agree to settle. In such event, the Company could be required to pay substantial fines and sanctions and/or implement additional remedial measures; in addition, it may be determined that the Company violated the FCPA.

Other Litigation

In addition to the investigations discussed above, the Company is involved in other disputes, litigations, and legal proceedings. The Company intends to aggressively defend itself in these matters, and while there can be no assurances and the outcome of these matters is currently not determinable, the Company currently believes that none of these existing claims or proceedings are likely to have a material adverse effect on its financial position. Notwithstanding the foregoing, there are many uncertainties associated with any litigation and these matters or other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could adversely affect gross margins in future periods. If any of those events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, if any, which could result in the need to adjust the liability and record additional expenses.

The Company records an accrual for loss contingencies for legal proceedings when it believes that an unfavorable outcome is both (a) probable and (b) the amount or range of any possible loss is reasonably estimable. The Company has not recorded any accrual for loss contingencies associated with such legal proceedings or the investigations discussed above. However, the Company has accrued for unrecognized tax benefits in connection with certain tax-related proceedings as described in further detail in Note 12, Incomes Taxes .

Note 15. Subsequent Events

BTI Acquisition

On April 1, 2016, the Company acquired BTI Systems Inc. (“BTI”), a provider of cloud and metro optical networking systems and software to content, cloud and service providers, for $65.0 million in cash (inclusive of the repayment of $23.9 million of certain outstanding BTI liabilities), subject to adjustments for working capital, cash on hand, and certain tax credits. Additionally, the Company assumed restricted stock units outstanding at closing. The Company believes that this acquisition will allow the Company to accelerate the delivery of open and automated packet optical transport solutions with integrated network management based on BTI Systems' proNX Service Manager and Juniper's Connectivity Services Director, as well as NorthStar Controller. The Company believes that, together, these products provide a unified management interface for multi-layer provisioning of end-to-end services across IP and optical networks.

Dividend Declaration

On April 28, 2016, the Company announced that it had declared a cash dividend of $0.10 per share of common stock payable on June 22, 2016 to stockholders of record as of the close of business on June 1, 2016.

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

This Quarterly Report on Form 10-Q, which we refer to as the Report, including “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., which we refer to as “we,” “us,” or the “Company,” that are based on our current expectations, estimates, forecasts, and projections about our business, economic and market outlook, 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. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, and 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 U.S. Securities and Exchange Commission, or the SEC. 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, except as required by applicable law.

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, or 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. 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. Each of these decisions has some impact on the financial results for any given period.

To aid in understanding our operating results for the periods covered by this Report, we have provided an executive overview and summary of our business and market environment along with a financial results overview. These sections should be read in conjunction with the more detailed discussion and analysis of our condensed consolidated financial condition and results of operations in this Item 2, our “Risk Factors” section included in Item 1A of Part II of this Report, and our unaudited Condensed Consolidated Financial Statements and Notes included in Item 1 of Part I of this Report, as well as our audited Consolidated Financial Statements and Notes included in Item 8 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 .

Business and Market Environment

At Juniper Networks, we design, develop, and sell products and services for high-performance networks to enable customers to build highly scalable, reliable, secure and cost-effective networks for their businesses, while achieving agility, efficiency and value through automation. We focus on customers and partners across our key market verticals who view these network attributes as fundamental to their business; including Telecom, Cable Providers, Cloud Providers, National Government, Financial Services, and Enterprise Strategic Verticals. We believe that product and solution differentiation, with a relentless customer focus, will enable us to achieve our goal of growing our revenue faster than the market.

Our products are sold in three geographic regions: Americas; Europe, Middle East, and Africa, or EMEA; and Asia Pacific, or APAC. Our high-performance routing, switching, and security networking products and service offerings are sold to Service Provider and Enterprise markets. We believe that our silicon, systems, and software represent innovations that transform the economics and experience of networking, helping our customers achieve superior performance, greater choice, and flexibility, while reducing overall total cost of ownership. In addition to our products, we offer technical support and professional services, as well as education and training programs to our customers. Together, our high-performance product and service offerings help our customers convert legacy networks that provide commoditized services into more valuable assets that provide differentiation, value, and increased performance, reliability, and security to end-users.

During the first quarter of 2016 , compared to the same period in 2015 , we saw an increase in net revenues in the Americas primarily driven by Cloud and Cable Providers, as well as growth in our Government vertical across all geographies.

Of our top ten customers for the first quarter of 2016 , five were Telecom customers, four were Cloud or Cable Providers, and one was an Enterprise. Of these customers, three were located outside of the U.S. This reflects our continued focus on diversifying our customer base.

33

Table of Contents

We remain constructive on revenue growth based on our continued focus on our key market verticals, our expectations with respect to the ramp up of our new product offerings, and our anticipated customer deployments. We believe our product gross margins may continue to vary in the future due to a mix of products sold and competitive pricing pressures; however, we expect to continue our focus on prudently managing our operating expenses.

We are focused on executing our strategy, of designing, developing and selling products and services for high-performance networks. We believe our product portfolio continues to be strong, and we remain focused on operational excellence, cost discipline and targeted growth initiatives, as well as partnerships and strategic acquisitions that complement our R&D strategy. For example, in April 2016, we acquired optical equipment provider BTI Systems Inc., or BTI, which we believe will allow us to accelerate the delivery of open and automated packet optical transport solutions with integrated network management based on BTI Systems' proNX Service Manager and our Connectivity Services Director, as well as our NorthStar Controller. We believe that, together, these products will provide a unified management interface for multi-layer provisioning of end to- end services across IP and optical networks. Further, our intent is to continue to focus on developing software solutions to help simplify the operation of networks, and to allow our customers across our key verticals to deliver real value over those networks. We anticipate that our increased focus on developing our software business will result in an increase in software revenue as a percentage of total revenue over time.

In the first quarter of 2016, we continued to execute our strategy with significant advancements in performance and automation across a number of key solution areas. First, with the introduction of our QFX10008 spine switch, which became generally available last quarter; we believe that our cloud solution now includes switching products across all layers of the data center, including our MX Universal Edge Router, our high-end SRX firewall, and our Contrail SDN controller.

Second, we believe our solution for wide area IP transport across Data Center Interconnect, Metro, and Core is enhanced with the introduction of our newest PTX line-cards, coupled with our multi-layer optimization controller, NorthStar, which we expect to combine with optical technology and talent from BTI.

To complement our solutions portfolio, we also solidified several new partnerships, including a global strategic partnership with Lenovo to build next-generation converged data center solutions for enterprise and web-scale customers. We also expanded our global alliances with NEC and AMDOCS to deliver NFV-based solutions that allow service providers and enterprises to gain greater service agility through automation.
We continue to deliver on our previously announced capital return program. In the first quarter of 2016, we repurchased $75.0 million of shares of our common stock and paid a quarterly cash dividend of $0.10 per share for an aggregate amount of $38.3 million . Since the first quarter of 2014, inclusive of share repurchases and dividends, we have returned approximately $3.75 billion of capital against our previously announced intention to return a total of $4.1 billion by the end of 2016. We intend to target a capital return policy of approximately 50% of annual free cash flow, inclusive of share repurchases and dividends, after completion of the $4.1 billion capital return program. Free cash flow is calculated as net cash provided by operating activities less capital expenditures.

In February 2016, we issued $350.0 million aggregate principal amount of 3.125% senior notes due 2019 , or the 2019 Notes, and $150.0 million aggregate principal amount of 4.500% senior notes due 2024 , or the 2024 Notes, and repaid $300.0 million of our previously issued senior notes that matured in March 2016.
On April 28, 2016, we announced a cash dividend of $0.10 per share of common stock payable on June 22, 2016 to stockholders of record as of the close of business on June 1, 2016.

•	Net Revenues: During the three months ended March 31, 2016 , compared to the same period in 2015 , net revenues increased primarily due to higher Service Provider net revenues in both the Americas and APAC, partially offset by a decrease in Enterprise net revenues across all geographies. Our revenue growth in the first quarter of 2016, compared to 2015, was also driven by higher net revenues from our switching products and services as well as higher net revenues from Cloud and Cable Providers in the Americas and our Government vertical across all geographies.	

•	Gross Margin: Our gross margin as a percentage of net revenues increased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to higher support revenue, improved labor productivity, and timing of spare parts purchases, which were partially offset by lower product revenue.	

•	Operating Income: Our operating income as a percentage of net revenues increased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to higher service net revenues, partially offset by higher operating expenses driven by an increase in sales and marketing expenses to capture the growth opportunities from our new products.	

•	Cash Dividends Declared per Common Stock: During the three months ended March 31, 2016 , we declared a quarterly cash dividend of $0.10 per share of common stock on January 27, 2016, which was paid on March 22, 2016 to stockholders of record on March 1, 2016 in the aggregate amount of $38.3 million . During the three months ended March 31, 2015, we declared a quarterly cash dividend of $0.10 per share of common stock on January 27, 2015, which was paid on March 24, 2015 to stockholders of record on March 3, 2015 in the aggregate amount of $40.8 million.	

•	Stock Repurchase Plan Activity: During the three months ended March 31, 2016 and March 31, 2015, we repurchased approximately 3.1 million and 17.4 million shares of our common stock in the open market, respectively, at an average price of $23.89 and $23.05 per share, respectively, for an aggregate purchase price of $75.0 million and $400.0 million, respectively.

•	Operating Cash Flows: Operating cash flows decreased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to fewer cash collections and higher payments related to employee incentive compensation.	

•	DSO: DSO is calculated as the ratio of ending accounts receivable, net of allowances, divided by average daily net revenues for the preceding 90 days. DSO for the first quarter of 2016 increased by 21 days, or 49% , compared to the same period in 2015 . The elevated DSO was primarily due to the implementation of our new enterprise resource planning, or ERP, system in the first quarter of 2016. This system change resulted in invoicing occurring later in the quarter than customary, which increased DSO by approximately 15 days. We anticipate DSO to return to our target range of 45 to 55 days in the second quarter of 2016.	

•	Product book-to-bill: Product book-to-bill represents the ratio of product orders booked divided by product revenues during the respective period. Product book-to-bill was greater than one for the three months ended March 31, 2016 and March 31, 2015 , respectively.	

•	Deferred Revenue: Total deferred revenue increased by $91.9 million to $1,260.0 million as of March 31, 2016 , compared to $1,168.1 million as of December 31, 2015 , primarily due to an increase in deferred service revenue of $71.1 million driven by an increase in multi-year support agreements, which are billed in advance, as well as product deferred revenue being marginally higher in the current period.	

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. On an ongoing basis, we evaluate our estimates and assumptions. These estimates and assumptions are based on current facts, historical experience, and various other factors that we believe are reasonable under the circumstances to determine reported amounts of assets, liabilities, revenue and expenses that are not readily apparent from other sources.

An accounting policy is considered to be critical if the nature of the estimates or assumptions is material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and the effect of the estimates and assumptions on financial condition or operating performance is material.

The accounting policies that we believe reflect our more significant estimates, judgments, and assumptions and are most critical to understanding and evaluating our reported financial results are as follows:  

•	Goodwill;	
		
•	Inventory Valuation and Contract Manufacturer Liabilities;	
		
•	Revenue Recognition;	
		
•	Income Taxes; and	
		
•	Loss Contingencies.	
 
During the three months ended March 31, 2016 , there were no significant changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates disclosed in Management's Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2015 .
 
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 Report, 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

We sell our high-performance networking products and service offerings across routing, switching, and security to two primary markets: Service Provider and Enterprise. Our determination of the market to which a particular revenue transaction relates 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 and wireless carriers, and cable operators, as well as major Internet content and application providers. The Enterprise market is generally comprised of businesses; federal, state, and local governments; research and education institutions; and financial services.

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

Routing

Routing product net revenues was flat during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily as a result of a decline in revenues from our T and M series products, which was partially offset by a steady increase in revenues from our PTX and ACX series products. Additionally, year-over-year revenue growth from Cloud and Cable Providers were partially offset by a decline in revenue from Telecom.
 
Switching

Switching product net revenues increased during the three months ended March 31, 2016 , compared to the same period in 2015 , due to continued data center growth from our QFX family of products, partially offset by a decline in campus and branch. Additionally, an increase in revenues from Government and Cable Providers were partially offset by a decline in Enterprise.

Security
 
Security product net revenues decreased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to a decrease in revenues from Enterprise and Cloud Providers, partially offset by higher revenues from Government.

Service

The increase in service net revenues during the three months ended March 31, 2016 , compared to the same period in 2015 , was primarily driven by support contracts related to strong product shipments in fiscal 2015, as well as strong performance in customer contract renewals.

Americas

Net revenues in the Americas increased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to an increase in net revenues from Cloud and Cable Providers, partially offset by declines in Enterprise and Telecom.

EMEA

Net revenues in EMEA decreased during the three months ended March 31, 2016 , compared to the same period in 2015 . The year-over-year decline was due to timing of deployments for certain Tier 1 Telecoms, partially offset by growth in Government.

APAC

Net revenues in APAC increased during the three months ended March 31, 2016 , compared to the same period in 2015 , as a result of an increase in net revenues from the Service Provider market, which was partially offset by a decrease in net revenues from the Enterprise market.

Enterprise

Net revenues from the Enterprise market decreased during the three months ended March 31, 2016 , compared to the same period in 2015 , as a result of a decrease in net revenues in the Americas and APAC. Additionally, revenue across our routing, switching, and security products decreased, but was partially offset by an increase in service revenues.

Customer

No customer accounted for 10% or more of our net revenues during the three months ended March 31, 2016 and March 31, 2015 .

Gross Margins

Percentage of net revenues	62.9	%	 	61.6	%	 	 	 	 	

Our gross margins have been and will continue to be affected by a variety of factors, including the mix and average selling prices of our products and services, new product introductions and enhancements, manufacturing costs, expenses for inventory obsolescence and warranty obligations, cost of support and service personnel, and the mix of distribution channels through which our products are sold.

Product gross margin

Product gross margin as a percentage of product revenues increased slightly during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to higher cost savings, which was partially offset by lower sales volume.

Service gross margin

Service gross margin as a percentage of service net revenues increased during the three months ended March 31, 2016 , compared to the same period in 2015 , due to higher support revenue, improved labor productivity, and timing of spare parts purchases.

Table of Contents

Our operating expenses have historically been driven in large part by personnel-related costs, including wages, commissions, bonuses, benefits, share-based compensation, and travel, particularly with respect to research and development and sales and marketing activities. Facilities and information technology, or IT, costs are allocated to each department based on usage and headcount.

Research and Development

Research and development expense increased slightly during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to higher depreciation and amortization expense, partially offset by a decrease in personnel-related expenses, primarily due to a decline in salary and bonus expense.

Sales and Marketing

Sales and marketing expense increased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to higher personnel-related expenses driven by an increase in headcount as well as higher marketing-related expenses to capture the growth opportunities from our new products.

General and Administrative

General and administrative expense increased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to higher legal costs and costs related to the acquisition of BTI which closed in April 2016.

Restructuring and Other Charges

In connection with the restructuring plan we initiated in the first quarter of 2014, which we refer to as the 2014 Restructuring Plan, we recorded $1.4 million of restructuring and other charges in the first quarter of 2015, primarily related to severance. We recorded no such charges during the first quarter of 2016. The 2014 Restructuring Plan and other restructuring plans have been substantially completed as of December 31, 2014, and we do not expect to record significant future charges under these restructuring plans.

Share-Based Compensation
 
Share-based compensation expense associated with equity incentive awards, which we refer to as awards, which include stock options, restricted stock units, or RSUs, restricted stock awards, or RSAs and performance share awards, or PSAs, as well as our Employee Stock Purchase Plan, or ESPP, was recorded in the following cost and expense categories (in millions, except percentages):

															
 	Three Months Ended March 31,	
 	2016	 	2015	 	$ Change	 	% Change	
Cost of revenues - Product	$	1.9		 	$	1.7		 	$	0.2		 	12	%

General and administrative	4.7		 	4.4		 	0.3		 	7	%	
Total	$	51.8		 	$	46.0		 	$	5.8		 	13	%	

Share-based compensation expense increased during the three months ended March 31, 2016 , as compared to the same period in 2015 , primarily due to an increase in actual shares vested during the period as well as an increase in grant date fair values due to higher stock prices.

Other Expense, Net

Interest income primarily includes interest earned from our cash, cash equivalents, investments, and on the promissory note issued to Juniper in connection with the sale of Junos Pulse. Interest expense primarily includes interest, net of capitalized interest expense, from payables with respect to our short-term and long-term debt and customer financing arrangements. Other typically consists of foreign exchange gains and losses and other non-operational income and expense items.

Total other expense, net increased during the three months ended March 31, 2016 , compared to the same period in 2015 , primarily due to a loss on investments in the first quarter of 2016, as well as an increase in interest expense, partially offset by higher interest income. The loss on investments was due to an impairment charge of $5.1 million recorded on our privately-held investments. The increase in interest expense was due to the issuance of the 2019 Notes and 2024 Notes in February 2016 and related interest recorded in the first quarter of 2016, compared to the same period in 2015. The increase in interest income was due to higher yields on our investments.

Income Tax Provision

The effective tax rates for the three months ended March 31, 2016 and March 31, 2015, reflect the recognition of a discrete tax benefit of approximately $1.9 million due to a loss on privately-held equity investments and $1.3 million related to restructuring charges, respectively. The effective rate for the three months ended March 31, 2015 does not reflect the benefit of the federal R&D credit which was permanently reinstated on December 18, 2015 and a change in the tax treatment of share-based compensation in our cost-sharing arrangement, which occurred in the three months ended September 30, 2015.
Our effective tax rate could fluctuate significantly on a quarterly basis and could be adversely affected to the extent earnings are lower than anticipated in countries that have lower statutory rates and higher than anticipated in countries that have higher statutory rates. Our effective tax rate could also fluctuate due to changes in the valuation of our deferred tax assets or liabilities, or by changes in tax laws, regulations, or accounting principles, as well as certain discrete items. See Item 1A of Part II, "Risk Factors" of this Report for a description of relevant risks which may adversely affect our results.

For further explanation of our income tax provision, see Note 12, Income Taxes , in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report.

(*)  	During the three months ended March 31, 2016, we adopted Accounting Standards Update, or ASU, No. 2015-03 (Subtopic 835-30) - S implifying the Presentation of Debt Issuance Costs . The balance as of December 31, 2015 was retrospectively adjusted to conform to the current-year presentation.	
The significant components of our working capital are cash and cash equivalents, short-term investments, and accounts receivable, reduced by short-term debt, accounts payable, accrued liabilities, and short-term deferred revenue. Working capital increased by $648.4 million during the three months ended March 31, 2016 primarily due to increases in cash and cash equivalents and short-term investments and decreases in short-term debt and accrued compensation, partially offset by increases in accounts payable and short-term deferred revenue.

Summary of Cash Flows

As of March 31, 2016 , compared to December 31, 2015 , our cash and cash equivalents increased by $225.1 million primarily due to proceeds from the issuance of our 2019 Notes and 2024 Notes, proceeds from the sales and maturities of available-for-sale investments, and cash from operations, partially offset by purchases of available-for-sale investments, repayment of our 2016 Notes, purchases and retirement of our common stock in connection with our stock repurchase program, capital expenditures, and dividend payments.

The following table summarizes cash flows from our Condensed Consolidated Statements of Cash Flows (in millions, except percentages):

															
 	Three Months Ended March 31,	
 	2016	 	2015	 	$ Change	 	% Change	
Net cash provided by operating activities	$	172.4		 	$	219.3		 	$	(46.9	)	 	(21	)%

Net cash provided by financing activities	$	104.3		 	$	185.3		 	$	(81.0	)	 	(44	)%	

Operating Activities

Net cash provided by operations for the three months ended March 31, 2016 was $172.4 million , compared to $219.3 million for the same period in 2015 . The decrease was primarily due to fewer cash collections and higher payments related to employee incentive compensation during the three months ended March 31, 2016 .

Investing Activities

For the three months ended March 31, 2016 , net cash used in investing activities was $57.2 million , compared to net cash used in investing activities of $221.3 million for the three months ended March 31, 2015 . The lower net cash used in investing activities was primarily due to higher proceeds from the sales and maturities of available-for-sale investments as well as lower purchases of available-for-sale investments during the three months ended March 31, 2016, compared to the same period on 2015.

Financing Activities

Net cash provided by financing activities was $104.3 million for the three months ended March 31, 2016 , compared to $185.3 million for the same period in 2015 . The net cash provided by financing activities in the three months ended March 31, 2016 decreased primarily due to repayment of our 2016 Notes, as well as fewer proceeds from the issuance of our 2019 Notes and 2024 Notes compared to the senior notes we issued in 2015, offset by fewer purchases and retirements of our common stock.

Stock Repurchase Activities

In February 2014, our Board of Directors, which we refer to as the Board, approved a stock repurchase program that authorized us to repurchase up to $2.1 billion of our common stock, including $1.2 billion pursuant to an accelerated share repurchase program, or the 2014 Stock Repurchase Program. In October 2014 and July 2015, the Board authorized a $1.3 billion and $500.0 million increase, respectively, to the 2014 Stock Repurchase Program for a total of $3.9 billion . As of March 31, 2016 , there was $457.5 million of authorized funds remaining under the 2014 Stock Repurchase Program.

During the three months ended March 31, 2016 , we repurchased and retired approximately 3.1 million shares of our common stock under the 2014 Stock Repurchase Program at an average price of $23.89 per share for an aggregate purchase price of $75.0 million .

Since the first quarter of 2014, inclusive of share repurchases and dividends, we have returned approximately $3.75 billion of capital to shareholders against our commitment to return $4.1 billion by the end of 2016. We intend to target a capital return policy of approximately 50% of annual free cash flow, inclusive of share repurchases and dividends, after completion of the $4.1 billion capital return program. Free cash flow is calculated as net cash provided by operating activities less capital expenditures.

Future stock repurchases under our stock repurchase program will be subject to a review of the circumstances 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. See Note 15, Subsequent Events, in Notes to Condensed Consolidated Financial Statements in Item 1 Part I of this Report, for discussion of our stock repurchase activity subsequent to March 31, 2016 .

Dividends

During the three months ended March 31, 2016 , we declared a quarterly cash dividend of $0.10 per share of common stock on January 27, 2016 which was paid on March 22, 2016 to stockholders of record on March 1, 2016 in the aggregate amount of $38.3 million . Any future dividends, and the establishment of record and payment dates, are subject to approval by the Board of Juniper Networks or authorized committee thereof. See Note 15, Subsequent Events, in Notes to Condensed Consolidated Financial Statements in Item 1 Part I of this Report, for discussion of our dividend declaration subsequent to March 31, 2016 .

Deferred Revenue

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

								
 	As of	
 	March 31,
2016	 	December 31,
2015	
Deferred product revenue:	 	 	 	
Undelivered product commitments and other product deferrals	$	205.6		 	$	210.1		
Distributor inventory and other sell-through items	102.8		 	81.8		
Deferred gross product revenue	308.4		 	291.9		
Deferred cost of product revenue	(47.3	)	 	(51.6	)	
Deferred product revenue, net	261.1		 	240.3		
Deferred service revenue	998.9		 	927.8		
Total	$	1,260.0		 	$	1,168.1		

Total deferred revenue increased by $91.9 million to $1,260.0 million as of March 31, 2016 , compared to $1,168.1 million as of December 31, 2015 , primarily due to an increase in deferred service revenue of $71.1 million driven by an increase in multi-year support agreements, which are billed in advance, as well as product deferred revenue being marginally higher in the current period.

Off-Balance Sheet Arrangements

As of March 31, 2016 , we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. It is not our business practice to enter into off-balance sheet arrangements. However, in the normal course of business, we enter into contracts consisting of guarantees of product and service performance, guarantees related to third-party customer-financing arrangements, customs and duties guarantees, and standby letters of credit for certain lease facilities. See Note 14, Commitments and Contingencies , in Notes to the Condensed Consolidated Financial Statements in Item 1 of Part I of this Report for additional information regarding our guarantees.

Contractual Obligations

As of March 31, 2016 , our principal commitments consist of obligations under operating leases, purchase commitments, debt, and other contractual obligations. There have been no significant changes to these obligations, during the three months ended March 31, 2016 compared 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, 2015 , other than the obligations listed in the table below (in millions):

(*)  	For further explanation of our debt, see Note 8, Debt and Financing , in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report.	

During the three months ended March 31, 2016, we also repaid the aggregate principal amount owed of $300.0 million on our 2016 Notes.

Revolving Credit Facility

On June 27, 2014, we entered into a Credit Agreement with certain institutional lenders that provides for a five year $500.0 million unsecured revolving credit facility, with an option to increase the amount of the credit facility by up to an additional $200.0 million , subject to certain conditions. Proceeds from borrowing made under the Credit Agreement may be used by us for working capital and general corporate purposes. Revolving loans may be borrowed, repaid and reborrowed until June 27, 2019, at which time all amounts borrowed must be repaid.

The Credit Agreement requires us to maintain a leverage ratio no greater than 3.0 x and an interest coverage ratio no less than 3.0 x during the term of the credit facility. In addition, the Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the ability of the Company and its subsidiaries to, among other things, grant liens, merge or consolidate, dispose of all or substantially all of its assets, change their accounting or reporting policies, change their business and incur subsidiary indebtedness, in each case subject to customary exceptions for a credit facility of this size and type. As of March 31, 2016 , the Company was in compliance with all covenants in the Credit Agreement, and no amounts were outstanding. See Note 8, Debt and Financing , in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report.

Guarantees

We have entered into agreements with customers that contain indemnification provisions relating to potential situations where claims could be alleged that our products solely, or in combination with other third party products, infringe the intellectual property rights of a third-party. As of March 31, 2016, we recorded a $15.6 million liability for such indemnification obligations in other accrued liabilities in the Condensed Consolidated Balance Sheets in Item 1 of Part I of this Report. We also have financial guarantees consisting of guarantees of product and service performance, guarantees related to third-party customer-financing arrangements, custom and duty guarantees, and standby letters of credit for certain lease facilities. Under certain third-party customer financing arrangements that contain guarantee provisions, which have terms of up to four years, we are liable for the aggregate unpaid payments to the third-party financing company in the event of customer default. As of March 31, 2016 , we have not made any

44

payments under these arrangements. As of March 31, 2016 and December 31, 2015 , we had $6.1 million and $15.8 million , respectively, in financing guarantees, bank guarantees, and standby letters of credit related to these financial guarantees.

Liquidity and Capital Resources

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, in 2014, we indicated that we intend to return $4.1 billion to our stockholders in the form of stock repurchases and dividends from February 2014 through the end of 2016. To the extent we repurchase additional shares of our common stock under our stock repurchase program or pay cash dividends on our common stock, our liquidity may be impacted. As of March 31, 2016 , 89% of our cash, cash equivalents, and investment balances were held outside of the U.S., which may be subject to U.S. taxes if repatriated.

In August 2013, we filed an automatic shelf registration statement with the SEC enabling us to offer for sale, from time to time, an unspecified amount of securities in one or more offerings and is intended to give us flexibility to take advantage of financing opportunities as needed or deemed desirable in light of market conditions. Our 2019 Notes and 2024 Notes were issued under the automatic shelf registration statement pursuant to a prospectus supplement filed with the SEC on February 24, 2016. Our 2020 Notes and 2025 Notes were issued under the automatic shelf registration statement pursuant to a prospectus supplement filed with the SEC on February 26, 2015 and our $350.0 million in principal amount of our 2024 Notes, which form a single series and are fully fungible with our 2024 Notes issued in 2016, were issued under the automatic shelf registration statement pursuant to a prospectus filed with the SEC on February 28, 2014. Any other offerings of securities under the automatic shelf registration statement will be made pursuant to a prospectus. In addition, our Revolving Credit Facility will also provide additional flexibility for future liquidity needs.

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. For fiscal year 2016, we intend to target the number of shares underlying equity awards granted on an annual basis at 2.40% or less of our common stock outstanding on a pure share basis (where each option, RSU, RSA or PSA granted is counted as one share). Based upon shares underlying our grants to date of options, RSUs, RSAs, and PSAs, we believe we are on track with respect to this goal for 2015.

Based on past performance and current expectations, we believe that our existing cash and cash equivalents, short-term, and long-term investments, together with cash generated from operations and access to capital markets and the revolving credit facility under the Credit Agreement will be sufficient to fund our operations, planned stock repurchases and dividends, and anticipated growth for at least the next twelve 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, but not limited to:

•	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;	

•	payment of dividends;	

•	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;

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

•	our relationships with suppliers, partners, and customers;	

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

•	expenses related to future restructuring plans;	

•	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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our exposures to market risk have not changed materially since December 31, 2015 . 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, 2015 .

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 Over Financial Reporting

During the first quarter of 2016, we completed the final phase of our multi-phase conversion to a new enterprise resource planning ("ERP") system by implementing the Customer Relationship Management, or CRM, and Financial Accounting & Reporting modules. As a result of this implementation, internal controls were modified to align with the modified business processes and new system-based controls were implemented to adapt to the new ERP system functionalities. Additional interim internal controls were put into operation to mitigate risks that may arise during the initial phase of post-implementation stabilization and we expect that such interim controls will be phased out over the next few quarters.

Except as described above, there were no changes in our internal control over financial reporting that occurred during the first quarter of 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

The information set forth under the “Legal Proceedings” section in Note 14, Commitments and Contingencies , in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report, is incorporated herein by reference.

Item 1A. Risk Factors

Factors That May Affect Future Results

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

Our quarterly results are unpredictable and subject to substantial fluctuations; 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 vary quarter by quarter and be unpredictable include, but are not limited to: limited visibility into customer spending plans, changes in the mix of products and services sold, changes in the mix of geographies in which our products and services are sold, changing market and economic conditions, current and potential customer, partner and supplier consolidation and concentration, competition, long sales and implementation cycles, unpredictable ordering patterns, changes in the amount and frequency of share repurchases or dividends, regional economic and political conditions, and seasonality. For example, we, and many companies in our industry, experience adverse seasonal fluctuations in customer spending, particularly in the first quarter. Furthermore, market trends, competitive pressures, commoditization of products, seasonal rebates, increased component or shipping costs, issues with product quality, regulatory impacts and other factors may result in reductions in revenue or pressure on gross margins of certain segments in a given period, which may necessitate adjustments to our operations. Such adjustments may be difficult or impossible to execute in the short or medium term.

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

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

Our revenues and gross margin depend significantly on general economic conditions and the demand for products in the markets in which we compete. Economic weakness or uncertainty, customer financial difficulties, and constrained spending on network expansion and enterprise infrastructure have in the past resulted in, and may in the future result in, decreased revenues and earnings. Such factors could make it difficult to accurately forecast sales and operating results and could negatively affect our ability to provide accurate forecasts to our contract manufacturers and manage our contract manufacturer relationships and other expenses. In addition, economic instability or uncertainty, as well as continued turmoil in the geopolitical environment in many parts of the world, have, and may continue to, put pressure on economic conditions, which has led and could lead, to reduced demand for our products, to delays or reductions in network expansions or infrastructure projects, and/or higher costs of production. More generally-speaking, 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, instability in the global credit markets may adversely impact the ability of our customers to adequately fund their expected capital expenditures, which could lead to delays or cancellations of planned purchases of our products or services. 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. Therefore, fluctuations in revenue could cause significant variations in our operating results and operating margins from quarter to quarter.

48

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 result in price concessions in certain markets or have a material adverse effect on demand for our products and consequently on our business, financial condition, and results of operations.

Our success depends upon our ability to effectively plan and manage our resources and restructure our business through rapidly fluctuating economic and market conditions, and such actions may have an adverse effect on our financial and operating results.

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

In periods of market expansion, we have increased investment in our business by, for example, increasing headcount and increasing our investment in R&D, sales and marketing, and other parts of our business. Conversely, in 2014, to refocus the Company’s strategy, optimize its structure and improve operational efficiencies, we implemented a new strategic focus, realigned our organization into a One-Juniper structure, reduced our workforce, consolidated and closed facilities, made changes to enhance efficiency, improved cost management measures and instituted a new capital allocation plan. In connection with our cost management measures, we implemented a substantial cost reduction plan accomplished through various restructuring activities across research and development, sales and marketing and general and administrative. We recorded a goodwill impairment charge of $850.0 million in the fourth quarter of 2014 due to the underperformance of our Security reporting unit and product rationalizations. Further strategy-related pivots could lead to delays in achieving revenue and profit forecasts and result in additional impairment. Some of our expenses are fixed costs that cannot be rapidly or easily adjusted in response to fluctuations in our business or numbers of employees. Rapid changes in the size, alignment or organization of our workforce, including sales account coverage, 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 and financial objectives. Our ability to achieve the anticipated cost savings and other benefits from our restructuring initiatives within the expected time frame is subject to many estimates and assumptions. These estimates and assumptions are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, if we are unsuccessful at implementing changes, or if other unforeseen events occur, our business and results of operations could be adversely affected.

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

A material portion of our net revenues depend on sales to a limited number of customers and distribution partners, particularly in our service provider market. Changes in the business requirements, vendor selection, project prioritization, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased) of our key customers could significantly decrease our 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, Altice’s purchase of Portugal Telecom, Liberty Global's proposed acquisition of Cable & Wireless Communications, AT&T’s acquisition of DirecTV, and Charter Communications, Inc.'s proposed acquisition of Time Warner Cable, Inc.) and that consolidation trend has continued. If our customers or partners are parties to consolidation transactions they may delay, suspend or indefinitely reduce or cancel their purchases of our products or other direct or indirect unforeseen consequences could harm our business, financial condition, and results of operations.

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

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

49

Table of Contents

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 and enhancements or entry into new markets with different pricing and cost structures. For example, in fiscal year 2015, our margins increased compared to fiscal year 2014, as a result of higher restructuring and other (benefit) charges recorded in 2014 but not in 2015, in connection with the restructuring plan we initiated in the first quarter of 2014. In fiscal year 2014, our margins declined compared to fiscal year 2013, as a result of higher inventory charges resulting from product rationalizations in connection with our 2014 restructuring plan and an industry-wide memory product quality defect for a component from a third party. 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. Failure to sustain or improve our gross margins reduces our profitability and may have a material adverse effect on our business and stock price.

Further, we will continue to remain diligent in our long-term financial objective to increase revenue and operating margins and manage our operating expenses as a percentage of revenue. We expect that our margins will vary with our ability to achieve these goals. We can provide no assurance that we will be able to achieve all of the goals of these plans or meet our announced expectations, in whole or in part, or that our plans will have the intended effect of improving our margins on the expected timeline, or at all.

Conversion of key internal systems and processes, particularly our ERP system, and problems with the design or implementation of these systems and processes could interfere with, and therefore harm, our business and operations.

We have underway a multi-phase project to convert certain key internal systems and processes, including our customer relationship management, or CRM, system and enterprise resource planning, or ERP, system. Since 2012, we have been implementing major changes to our ERP system, which activities we expect to continue into 2016. In the third quarter of 2014, we implemented the manufacturing, fulfillment, and inventory portion of this ERP project and were reliant upon dual ERP systems until January 2016 when we moved to a single ERP System. In connection with the transfer to our new ERP system, we scheduled a shutdown of certain of our legacy ERP systems, which impacted our DSO in the first quarter of 2016. We are still early in the process of operating under our new ERP system and may need to resolve issues that arise in connection with this transition. We have invested, and will continue to invest, significant capital and human resources in the design and implementation of these systems and processes. Any problems, disruptions, delays or other issues in the design and implementation of the new systems or processes, particularly any 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, collect cash from our customers, maintain our DSO measure, fulfill contractual obligations, record and transfer information in a timely and accurate manner, recognize revenue, file SEC reports in a timely manner, or otherwise run our business. Even if we do not encounter these adverse effects, as noted above, the design and implementation of these new systems and processes may be much more costly than we anticipated and in the event of lengthy project delays, we may experience issues with retention of the implementation team. 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 lengthy or costly than anticipated, our business, financial condition, and results of operations could be negatively impacted.

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 serve. The network equipment market has historically been dominated by Cisco, with competition coming from other companies such as Nokia Corporation (following its acquisition of Alcatel-Lucent), Arista, Brocade, HP, and Huawei. In the security market, we face intense competition from Cisco and Palo Alto Networks, as well as companies such as Check Point, F5 Networks, Fortinet, and HP. Further, a number of other small public and private companies have products or have announced plans for new products to address the same challenges and markets that our products address.

In addition, actual or speculated consolidation among competitors, or the acquisition by, or of, our partners and/or resellers by competitors can increase the competitive pressures faced by us as customers may delay spending decisions or not purchase our products at all. For example, in recent years, Nokia Corporation merged with Alcatel-Lucent, HP acquired Aruba Networks, and Cisco acquired OpenDNS and Sourcefire, Inc., which further consolidated our market. In addition, Dell announced a proposed acquisition of EMC, which we anticipate will further consolidate our market upon its consummation. 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. In addition, some of our competitors have become more integrated, including through consolidation, and offer a broader range of products and services, which could make their solutions more attractive to our customers. Many of our competitors sell networking products as bundled solutions with other IT products, such as computer and storage systems. 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. Our partners and resellers generally sell or resell competing products on a non-exclusive basis and consolidation could delay spending or require us to increase discounts to compete, which could also adversely affect our business.

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, both of which may be exacerbated by the impact of continued global economic weakness, may cause revenues and operating results to vary significantly and unexpectedly from quarter-to-quarter.

The timing of product orders and/or our reliance on revenue from sales of software or subscription and support and maintenance services may cause us to recognize revenue in a different period than the one in which a transaction takes place. This may make it difficult for investors to observe quarterly trends and may cause significant variations in our operating results and operating margin on a quarterly basis.

Generally, our network equipment products are stocked only in limited quantities by our distributors and resellers due to the cost, complexity and custom nature of configurations required by our customers; we generally build such products as orders are received. The volume of orders received late in any given fiscal quarter remains unpredictable. If orders for certain products are received late in any quarter, we may not be able to recognize revenue for these orders in the same period, which could adversely affect our ability to meet our expected revenues for such quarter.

In addition, services revenue accounts for a significant portion of our revenue, comprising 27%, 26%, and 25% of total revenue in fiscal year 2015, 2014, and 2013, respectively. Sales of new or renewal support and maintenance contracts may decline and/or fluctuate as a result of a number of factors, including end-customers’ level of satisfaction with our products and services, the prices of our products and services, the prices of products and services offered by our competitors, and reductions in our end-customers’ spending levels. We recognize support and maintenance revenue periodically over the term of the relevant service period.

The introduction of new software products is part of our intended strategy to expand our software business, and software revenues may be recognized periodically over the term of the relevant use period or subscription period. As a result, much of the software, subscription and support and maintenance revenue we report each fiscal quarter is the recognition of deferred revenue from software, subscription and support and maintenance contracts entered into during previous fiscal quarters. Consequently, a decline in new or renewed contracts in any one fiscal quarter will not be fully or immediately reflected in revenue in that fiscal quarter but will negatively affect our revenue in future fiscal quarters. Accordingly, the effect of significant downturns in new or renewed sales of our software, subscriptions or support and maintenance is not reflected in full in our operating results until future periods. Also, it is difficult for us to rapidly increase our software or services revenue through additional software or services sales in any period, as revenue from new and renewal software, subscription and support and maintenance contracts must be recognized over the applicable service period.

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.

If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products, product enhancements and business strategies that meet those technological shifts, needs and opportunities, or if those products are not made available or strategies are not executed 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.

The markets for our products are characterized by rapid technological change, frequent new product introductions, changes in customer requirements, continued price pressures and a constantly evolving industry. We cannot guarantee that we will be able to anticipate future technological shifts, market needs and opportunities or be able to develop new products, product enhancements or business strategies to meet such technological shifts, needs or opportunities in a timely manner or at all. For example, the move from traditional network infrastructures towards software-defined networking, or SDN, has been receiving considerable attention. In our view, it will take several years to see the full impact of SDN, and we believe the successful products and solutions in this market will combine hardware and software elements. If we fail to anticipate market requirements or opportunities or fail to develop and introduce new products, product enhancements or business strategies to meet those requirements or opportunities 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 and services, 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, enhancements or business strategies, there can be no assurance that new products, enhancements or business strategies will achieve widespread market acceptance.

In the past two years, we have announced a number of new products and enhancements to our hardware and software products across routing, switching and security, including ACX5000 and ACX500 routers, QFX10000 line of spine switches, QFX5100, QFX5200, QFX5100-AA, QFX-PFA, SRX300, SRX1500, SRX5000 with Express Path and SRX5800 Series Services Gateways, EX9200 and EX4600 Ethernet Switches, new MX Series line cards and routers (including the vMX 3D Universal Edge Router), new PTX Series line cards (powered by our ExpressPlus custom silicon), Junos Fusion Provider Edge, Junos Fusion Data Center, Junos Fusion Enterprise, a disaggregated version of Junos Software, OCX1100, PTX1000, vSRX Virtual Firewall, Sky Advanced Threat Prevention (ATP), Spotlight Secure, Junos Space Security Director, Junos Space Virtual Director, Juniper Networks Contrail Networking, Juniper Networks Cloud CPE solution and NFX250 network services platform. We also introduced Juniper Networks Unite, a new reference architecture that provides network infrastructure solutions for enterprise campus and branch networks. The success of our new products depends on several factors, including, but not limited to, component costs, timely completion and introduction of these products, prompt resolution of any defects or bugs in these products, differentiation of new products from those of our competitors and market acceptance of these products.

The introduction of new software products is part of our intended strategy to expand our software business. We have also begun to disaggregate certain software from certain hardware products, such that customers would be able to purchase or license our hardware and software products independently, which we expect could in time enable our hardware to be deployed with third party networking applications and services and our software to be used with third party hardware. For example, we have developed a disaggregated version of our Junos software and recently introduced our QFX5200 series of switches, which runs our disaggregated Junos software. The success of our strategy to expand our software business, including our strategy to disaggregate software from certain hardware products, is subject to a number of risks and uncertainties, including:

•	the additional development efforts and costs required to create new software products and/or to make our disaggregated products compatible with multiple technologies;	

•	the possibility that our new software products or disaggregated products may not achieve widespread customer adoption;	

•	the potential that our strategy could erode our gross margins;	

•	the impact on our financial results of longer periods of revenue recognition and changes in tax treatment associated with software sales;	

•	the additional costs associated with regulatory compliance and changes we need to make to our distribution chain in connection with increased software sales;	

•	the ability of our disaggregated hardware and software products to operate independently and/or to integrate with current and future third party products; and	

•	the risk that issues with third party technologies used with our disaggregated products will be attributed to us.

If any of our new products or business strategies do not gain market acceptance or meet our expectations for growth, our ability to meet future financial targets may be adversely affected and our competitive position and our business and financial results could be harmed.

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

We depend on independent contract manufacturers (each of which is a third-party manufacturer for numerous companies) to manufacture our products. Although we have contracts with our contract manufacturers, these contracts do not require them to manufacture our products on a long-term basis in any specific quantity or at any specific price. In addition, it is time-consuming and costly to qualify and implement additional contract manufacturer relationships. Therefore, if we fail to effectively manage our contract manufacturer relationships, which includes failing to provide accurate forecasts of our requirements, or if one or more of them experiences delays, disruptions, or quality control problems in our manufacturing operations, or if we had to change or add additional contract manufacturers or contract manufacturing sites, our ability to ship products to our customers could be delayed. We have experienced in the past and may experience in the future an increase in the expected time required to manufacture our products or ship products. Such delays could result in supply shortfalls that damage our ability to meet customer demand for those products and could cause our customers to purchase alternative products from our competitors. Also, the addition of manufacturing locations or contract manufacturers or the introduction of new products by us 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 outside of the United States. Each of these factors could adversely affect our business, financial condition and results of operations.

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

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

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.

We rely on single or limited sources of certain of our components. 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 spike in growth in our business, or more likely in IT spending and the economy in general is likely to create greater short-term pressures on us and our suppliers to accurately forecast overall component demand and to establish optimal component inventories. If shortages or delays persist, the price of these components may increase, or the components 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 and other semiconductor chips, from single or limited sources and many of our component suppliers are concentrated in China. In addition, there has been consolidation among certain suppliers of our components. For example, GLOBALFOUNDRIES recently acquired IBM’s semiconductor manufacturing business, Avago Technologies Limited recently acquired Broadcom Corporation and Intel Corporation recently acquired Altera Corporation. Consolidation among suppliers can result in the reduction of the number of independent suppliers of components available to us, which could negatively impact our ability to access certain component parts or the prices we have to pay for such parts. Any disruptions to our supply chain could decrease our sales, earnings and liquidity or otherwise adversely affect our business and result in increased costs. Such a disruption could occur as a result of any number of events, including, but not limited to, increases in wages that drive up prices, the imposition of regulations, quotas or embargoes on key components, labor stoppages, transportation failures affecting the supply and shipment of materials and

53

Table of Contents

finished goods, the unavailability of raw materials, severe weather conditions, natural disasters, civil unrest, geopolitical developments, war or terrorism and disruptions in utility and other services.

The development of alternate sources for key components is time-consuming, difficult, and costly. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. Also, long-term supply and maintenance obligations to customers increase the duration for which specific components are required, which may further increase the risk of component shortages or the cost of carrying inventory. In the event of a component shortage or supply interruption from these suppliers, we may not be able to develop alternate or second sources in a timely manner. If we are unable to buy these components in quantities sufficient to meet our requirements on a timely basis, we will not be able to deliver products and services to our customers, which would seriously affect present and future sales, which would, in turn, adversely affect our business, financial condition, and results of operations.

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

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

Our future success is highly dependent upon establishing and maintaining successful relationships with a variety of value-added and other reseller and distribution partners, including our worldwide strategic partners such as Ericsson, IBM, Nokia Solutions and Networks O.Y., Dimension Data and NEC Corporation. The majority of our revenues are derived through value-added resellers and distributors, most of which also sell our competitors’ products, and some of which sell their own competing products. Our revenues depend in part on the performance of these partners. The loss of or reduction in sales to our resellers or distributors could materially reduce our revenues. For example, in 2011 and 2012, one of our OEM partners, Dell, acquired Force10 and SonicWall, both competitors of ours. As a result, Dell became increasingly competitive in certain areas, their resale of our products declined, and we ultimately terminated our OEM relationship with Dell. In addition, in 2016, Nokia Corporation merged with Alcatel-Lucent, a competitor of ours, and Cisco recently announced a partnership with Ericsson, which is one of our existing partners. Our competitors may in some cases be effective in leveraging their market share positions or in providing incentives to current or potential resellers and distributors to favor their products or to prevent or reduce sales of our products. If we fail to develop and maintain relationships with our partners, fail to develop new relationships with value-added resellers and distributors in new markets, fail to expand the number of distributors and resellers in existing markets, fail to manage, train or motivate existing value-added resellers and distributors effectively, determine that we cannot continue to do business with these partners for any reason 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. We also depend on our global channel partners to comply with applicable legal and regulatory requirements. To the extent that they fail to do so, that could have a material adverse effect on our business, operating results, and financial condition.

System security risks, data protection breaches, and cyber-attacks could compromise our proprietary information, disrupt our internal operations and harm public perception of our 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, personal data, our proprietary business information and proprietary business information of our customers, suppliers and business partners on our networks. In addition, we store sensitive data through cloud-based services that may be hosted by third parties and in data center infrastructure maintained by third parties. The secure maintenance of this information is critical to our operations and business strategy. The growing cyber

54

Table of Contents

risk environment means that individuals, companies, and organizations of all sizes including us, are increasingly subject to the threat of intrusions on their networks and systems by a wide range of actors on an ongoing and regular basis. Despite our security measures, and those of our third-party vendors, our information technology and infrastructure may be vulnerable to penetration or attacks by computer programmers, hackers or sophisticated nation-state and nation-state supported actors or breached due to employee error, malfeasance or other disruptions. If any breach compromises our networks, creates system disruptions or slowdowns or exploits security vulnerabilities of our products, the information stored on our networks could be accessed and modified, publicly disclosed, lost or stolen, and we may be subject to liability to our customers, suppliers, business partners and others, and suffer reputational and financial harm. In addition, sophisticated hardware and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including "bugs" and other problems that could unexpectedly interfere with the operation of our networks. This can be true even for “legacy” products that have been determined to have reached an end of life engineering status but will continue to operate for a limited amount of time.

For example, in December 2015, we disclosed that we identified unauthorized code in our ScreenOS security system that could allow a knowledgeable attacker to gain administrative access to NetScreen devices and to decrypt VPN connections. Following the identification of the ScreenOS vulnerabilities, we launched an investigation into the matter, developed patched releases for the latest versions of ScreenOS and notified customers, all of which required significant time and attention from management and our employees. In addition, we announced that we were making additional changes to ScreenOS in response to our additional analysis and, in April 2016, we announced that we had made those changes as a part of an update of ScreenOS. The investigation is ongoing. At this time, we do not have an estimate of third party costs related to the ScreenOS matter that could result from any third party claims brought against us, including, for example, indemnification for damages our customers may incur or actions instituted by governmental or regulatory entities that could result in fines or other penalties. Costs related to the ScreenOS matter, including the costs to resolve third party claims, costs relating to the investigation and the time and resources required to develop patched releases and further modify the products, may be material.

As a result of the ScreenOS matter, or any other actual or perceived breach of network security that occurs in our network or in the network of a customer of our products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness of our products and our overall reputation could be harmed. Because the techniques used by attackers, 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 or the vulnerabilities they have caused. This could impede our sales, manufacturing, distribution or other critical functions, which could have an adverse impact on our financial results. The economic costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software systems and security vulnerabilities, including the ScreenOS matter, could be significant and may be difficult to anticipate or measure because the damage may differ based on the identity and motive of the attacker, which are often difficult to pinpoint. Additionally, we could be subject to regulatory investigations, potential fines and litigation in connection with a security breach or related issue and be liable to third parties for these types of breaches.

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, data center providers 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, or IT, systems, the systems and processes of third parties, and the interfaces of our systems with the systems of third parties. For example, our order entry system feeds information into the systems of our contract manufacturers, which enables them to build and ship our products. If those systems fail or are interrupted, our processes may function at a diminished level or not at all. This could negatively impact our ability to ship products or otherwise operate our business, and our financial results could be harmed. For example, although it did not adversely affect our shipments, an earthquake in late December of 2006 disrupted our communications with China, where a significant part of our manufacturing occurs. In addition, as discussed earlier in this Risk Factors section, beginning in 2012 and continuing into 2016, we have been implementing major changes to our ERP system. Any failure of the new system or interruptions during the implementation process may impair communications with our manufacturers, and, therefore, adversely affect our ability to build and ship our products.
We are also in the process of further consolidating our on-site data centers to the cloud and to off-site facilities that are hosted and controlled by third-parties. These cloud providers and off-site facilities are vulnerable to damage, interruption or performance problems from earthquakes, hurricanes, floods, fires, power loss, telecommunications failures, equipment failure, adverse events caused by operator error and similar events. In addition, because we lease our cloud storage space and off-site data center facilities, we cannot be assured that we will be able to expand our data center infrastructure to meet user demand in a timely manner, or on favorable economic terms. If we have issues receiving and processing data, this may delay our ability to provide products and services to our customers and damage our business. We also rely upon the performance of the systems and processes of our contract

55

Table of Contents

manufacturers to build and ship our products. If those systems and processes experience interruption or delay, our ability to build and ship our products in a timely manner may be harmed. For example, we have experienced instances where our contract manufacturers were not able to ship products in the time periods expected by us, which prevented us from meeting our commitments to our customers. 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, cable and cloud service provider companies and our other large customers generally require onerous terms and conditions in our contracts with them. As we seek to sell more products to such customers, we may be required to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues.

Telecommunications, cable and cloud service provider companies, which comprise a significant portion of our customer base, and other large companies, generally have greater purchasing power than smaller entities and, accordingly, often request and receive more favorable terms from suppliers. For example, our customers, 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, increase our costs 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.

In addition, service providers have purchased products from other vendors who promised but failed to deliver certain functionality and/or had products that caused problems or outages in the networks of these customers. As a result, these customers may request additional features from us and require substantial penalties for failure to deliver such features or may require substantial penalties for any network outages that may be caused by our products. These additional requests and penalties, if we are required to agree to them, may require us to defer revenue recognition from such sales, which may negatively affect our business, financial condition and results of operations. In addition, increased patent litigation brought against customers by non-practicing entities in recent years, may result, and in some cases has resulted, in customers requesting or requiring vendors to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition and results of operations.

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

We, and certain of our current and former officers and current and former members of our Board of Directors, have been or 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. As noted in Note 14, Commitments and Contingencies , in Notes to Consolidated Financial Statements of this Report, under the heading of “Legal Proceedings”, the U.S. Securities and Exchange Commission, or the SEC, and the U.S. Department of Justice, or the DOJ, are conducting investigations into possible violations by the Company of the U.S. Foreign Corrupt Practices Act, or the FCPA, in a number of countries. The investigations relate to whether the Company or any third party on behalf of the Company gave money or anything else of value to any government official in violation of the FCPA. The Company’s Audit Committee, with the assistance of independent advisors, has been investigating and conducting a thorough review of possible violations of the FCPA, and has made recommendations for remedial measures, including employee disciplinary actions in foreign jurisdictions, which the Company has implemented and continues to implement. Litigation and investigations are inherently uncertain. We therefore cannot predict the duration, scope, outcome or consequences of litigation and government investigations. In connection with any government investigations, including those in which we are currently involved as described above, if the government takes action against us or we agree to settle the matter, we may be required to pay substantial fines and incur other sanctions, which may be material, and suffer reputational harm. The lawsuits and investigations are expensive and time-consuming to defend, settle, and/or resolve, and may require us to implement certain remedial measures that could prove costly or disruptive to our business and operations. The unfavorable resolution of one or more of these matters could have a material adverse effect on our business, results of operations, financial condition or cash flows.

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

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. Third parties have asserted and may in the future assert claims or initiate litigation related to patent, copyright, trademark, and other intellectual property rights to technologies and related standards that

56

Table of Contents

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. In addition, increased patent litigation brought by non-practicing entities in recent years may result, and in some cases has resulted, in our customers requesting or requiring us to absorb a portion of the costs of such litigation or providing broader indemnification for litigation, each of which could increase our expenses and negatively affect our business, financial condition and results of operations. 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, enter into license agreements, or cease engaging in certain activities or offering certain products or services. 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 or anyone we are required to indemnify by any third-party is successful, if we are required to settle litigation for significant amounts of money, if we fail to develop non-infringing technology or if we license required proprietary rights, our business, financial condition, and results of operations could be materially and adversely affected.

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

We are subject to laws and regulations affecting the sale of our products in a number of areas. For example, some governments have regulations prohibiting government entities from purchasing security products that do not meet specified indigenous certification criteria, even though those criteria may be in conflict with accepted international standards. Other regulations that may negatively impact our business include country of origin regulations. These types of regulations are in effect or under consideration in several jurisdictions where we do business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act includes disclosure requirements applicable to public companies regarding the use of “conflict minerals” mined from the Democratic Republic of Congo and adjoining countries, which we refer to collectively as the DRC, and procedures regarding a manufacturer's efforts to prevent the sourcing of such “conflict minerals.” These minerals are present in our products. SEC rules implementing these requirements may have the effect of reducing the pool of suppliers who can supply DRC “conflict free” components and parts, and we may not be able to obtain DRC conflict free products or supplies in sufficient quantities for our operations. Since our supply chain is complex, we may face reputational challenges with our customers, stockholders and other stakeholders if we are unable to sufficiently verify the origins for the "conflict minerals" used in our products.

In addition, environmental laws and regulations relevant to electronic equipment manufacturing or operations, including laws and regulations governing the hazardous material content of our products and laws relating to the collection of and recycling of electrical and electronic equipment, may adversely impact our business and financial condition. These laws and regulations include, among others, the European Union, or EU, Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Directive, or RoHS. The EU RoHS and the similar laws of other jurisdictions limit the content of certain hazardous materials such as lead, mercury, and cadmium in the manufacture of electrical equipment, including our products. Currently, our products comply with the EU RoHS requirements. However, certain exemptions are scheduled to lapse in the future, including an exemption for lead in network infrastructure equipment upon which we and our competitors rely, and which is currently scheduled to expire in July 2016. The lapse of this exemption, further changes to this or other laws, or passage of similar laws in the EU or other jurisdictions, would require us to cease selling non-compliant products in the EU and to reengineer our products to use components compatible with these regulations. This reengineering and component substitution could result in additional costs to us, disrupt our operations or logistics, and result in an adverse impact on our operating results. In addition, in validating the compliance of our products with applicable hazardous materials restrictions, we rely substantially on affirmations by our component suppliers as to the compliance of their products with respect to those same restrictions. Failure by our component suppliers to furnish accurate and timely information could subject us to penalties or liability for violation of such hazardous materials restrictions, interrupt our supply of products to the EU, and result in our customers refusing or being unable to purchase our products. Additionally, the EU and a number of other countries have adopted regulations requiring producers of electrical and electronic equipment to assume certain responsibilities for collecting, treating, recycling and disposing of products when they have reached the end of their useful life. Finally, the EU REACH regulations regulate the handling of certain chemical substances that may be used in our products.

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

57

Table of Contents

governing aspects of fixed broadband networks and wireless networks. These regulations, which are being challenged in court, might impact service provider and cloud provider business models and, as such, providers' needs for Internet telecommunications equipment and services. Also, many jurisdictions are evaluating or implementing regulations relating to cyber security, supply chain integrity, privacy and data protection, any of which can affect the market and requirements for networking and security equipment.

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

Governmental regulations and economic sanctions affecting the import or export of products generally or affecting products containing encryption capabilities could negatively affect our revenues and operating results.

The United States and various foreign governments have imposed controls and restrictions on the import or export of, among other things, our products that contain or use encryption technology. Most of our products contain or use encryption technology and, consequently, are subject to such controls, requirements and restrictions. In addition, from time to time, governmental agencies have proposed additional regulation of encryption technology, such as requiring certification, notifications, review of source code, limiting the encryption features or the escrow and governmental recovery of private encryption keys. For example, China recently has proposed new conditions on eligibility of encryption products for purchase by government and certain non-government organizations. India recently proposed and then withdrew regulations imposing serious conditions on the use of encryption in telecommunications products. In addition, the U.S. government also has broader sanctions and embargoes that generally forbid supply of most items (whether or not they include encryption) to or involving certain countries, territories, governments, legal entities and individuals, including recent restrictions imposed by the U.S. and EU on exports to Russia and Ukraine. We have implemented systems to detect and prevent sales into these countries or to prohibited entities or individuals, but there can be no assurance that they will always be effective.

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, or related economic sanctions could harm our international and domestic sales and adversely affect our revenues and operating results. In addition, failure to comply with such regulations could result in harm to our reputation and ability to compete in international markets, penalties, costs, seizure of assets (including source code) and restrictions on import or export privileges or adversely affect sales to government agencies or government-funded projects.

Our actual or perceived failure to adequately protect personal data could adversely affect our business, financial condition and results of operations.

A variety of state, national, foreign, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. These privacy- and data protection-related laws and regulations are evolving, with new or modified laws and regulations proposed and implemented frequently and existing laws and regulations subject to new or different interpretations. Compliance with these laws and regulations can be costly and can delay or impede the development and offering of new products and services.

For example, we historically have relied upon adherence to the U.S. Department of Commerce’s Safe Harbor Privacy Principles and compliance with the U.S.-EU Safe Harbor Framework agreed to by the U.S. Department of Commerce and the EU. The U.S.-EU Safe Harbor Framework, which established means for legitimizing the transfer of personal data by U.S. companies from the European Economic Area, or EEA, to the U.S., recently was invalidated by a decision of the European Court of Justice, or the ECJ. In light of the ECJ’s decision, we are reviewing our business practices and may find it necessary or desirable to make changes to our personal data handling procedures and contractual arrangements to ensure our transfer and receipt of EEA residents’ personal data remains legitimized under applicable European law. Our actual or alleged failure to comply with applicable laws and regulations, or to protect personal data, could result in enforcement actions, significant penalties or other legal action against us or our customers or suppliers, which could result in negative publicity, increase our operating costs, subject us to claims or other remedies and have a material adverse effect on our business, financial condition, and results of operations.

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, 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.

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

We are required to test intangible assets with indefinite lives, including goodwill, annually or more frequently if certain circumstances change that would more likely than not reduce the fair value of a reporting unit and intangible assets below their carrying values. As of March 31, 2016 , our goodwill was $2,981.3 million and there were no intangible assets with indefinite lives. When the carrying value of a reporting unit’s goodwill exceeds its implied fair value of goodwill, a charge to operations is recorded. If the carrying amount of an intangible asset with an indefinite life exceeds its fair value, a charge to operations is recorded. Either event would result in incremental expenses for that quarter, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred.

In the past, we recorded a goodwill impairment charge of $850.0 million due to the underperformance of our Security reporting unit and product rationalizations.

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

Our goodwill impairment analysis is sensitive to changes in key assumptions used in our analysis, such as expected future cash flows, the degree of volatility in equity and debt markets, and our stock price. If the assumptions used in our analysis are not realized, it is possible that an impairment charge may need to be recorded in the future. We cannot accurately predict the amount and timing of any impairment of goodwill or other intangible assets. However, any such impairment would have an adverse effect on our results of operations.

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

Our future effective tax rates could be subject to volatility or adversely affected by the following: earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated earnings in countries where we have higher statutory rates; changes in the valuation of our deferred tax assets and liabilities; expiration of, or lapses in, the R&D tax credit laws applicable to us; transfer pricing adjustments related to certain acquisitions, including the license of acquired intangibles under our intercompany R&D cost sharing arrangement; costs related to intercompany restructuring; tax effects of share-based compensation; challenges to our methodologies for valuing developed technology or intercompany arrangements; or changes in tax laws, regulations, accounting principles, or interpretations thereof. On October 5, 2015, the Organisation for Economic Co-operation and Development, or OECD, an international association of 34 countries including the U.S., published final proposals under its Base Erosion and Profit Shifting, or BEPS, Action Plan. The BEPS Action Plan includes fifteen Actions to address BEPS in a comprehensive manner and represents a significant change to the international corporate tax landscape. These proposals, if adopted by countries, may increase tax uncertainty and adversely affect our provision for income taxes. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service, or IRS, and other tax authorities. It is possible that tax authorities may disagree with certain positions we have taken and any adverse outcome of such a review or audit could have a negative effect on our financial position and operating results. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes, but the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment by management, and there are transactions where the ultimate tax determination is uncertain. Although we believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our consolidated financial statements and may materially affect our financial results in the period or periods for which such determination is made. There can be no assurance that the outcomes from continuous examinations will not have an adverse effect on our business, financial condition, and results of operations.

We may face difficulties enforcing our proprietary rights which could adversely affect our ability to compete.

We generally rely on a combination of patents, copyrights, trademarks, and trade secret laws and contractual restrictions on disclosure of confidential and proprietary information, to establish and maintain proprietary rights in our technology and products. Although we have been issued numerous patents and other patent applications are currently pending, there can be no assurance that any of our patent applications will result in issued patents or that any of our patents or other proprietary rights will not be challenged, invalidated, infringed or circumvented or that our rights will, in fact, provide competitive advantages to us or protect our technology, any of which could result in costly product redesign efforts, discontinuance of certain product offerings and other competitive harm.
In addition, despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. We generally enter into confidentiality or license agreements with our employees, consultants, vendors, and customers, and generally limit access to and distribution of our proprietary information. However, we cannot assure you that we have entered into such agreements with all parties who may have or have had access to our confidential information or that the agreements we have entered into will not be breached. We cannot guarantee that any of the measures we have taken will prevent misappropriation of our technology.

Furthermore, the laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States. The outcome of any actions taken in these foreign countries may be different than if such actions were determined under the laws of the United States. Although we are not dependent on any individual patents or group of patents for particular segments of the business for which we compete, if we are unable to protect our proprietary rights in a market, we may find ourselves at a competitive disadvantage to others who need not incur the substantial expense, time, and effort required to create innovative products that have enabled our success.

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

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

•	changes in general IT spending,	

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

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

•	varying and potentially conflicting laws and regulations;	

•	fluctuations in local economies;	

•	wage inflation or a tightening of the labor market; and	

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

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

Moreover, local laws and customs in many countries differ significantly from or conflict with those in the United States or in other countries in which we operate. 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 U.S. regulations applicable to us.

There can be no assurance that our employees, contractors, channel partners, and agents will not take actions in violation of our policies and procedures, which are designed to ensure compliance with U.S. and foreign laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners, or agents could result in termination of our relationship, financial reporting problems, fines, and/or penalties for us, or prohibition on the importation or exportation of our products, and could have a material adverse effect on our business, financial condition and results of operations.

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

Because a substantial portion 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. This could negatively affect our ability to meet our customers' pricing expectations in those markets and may result in erosion of gross margin and market share. 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, such attempts to offset the impact of currency fluctuations are costly and no amount of hedging can be effective against all circumstances, including long-term declines in the value of the U.S. Dollar. If our attempts to hedge against these risks are not successful, or if long-term declines in the value of the U.S. Dollar persist, our financial condition and results of operations could be adversely impacted.

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

We have made, and may continue to make, acquisitions in order to enhance our business. For example, in April 2016, we acquired BTI Systems Inc.; in 2014, we acquired WANDL, Inc.; and in 2012, we acquired Contrail Systems Inc. and Mykonos Software, Inc. Acquisitions involve numerous risks, including problems combining the purchased operations, technologies or products, unanticipated costs and liabilities, 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.

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

Approximately $125 million of the transaction consideration we received from the divestiture of our Junos Pulse product portfolio is in the form of a non-contingent seller promissory note and we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, by the buyer under the note.

In the fourth quarter of fiscal 2014, we completed the sale of our Junos Pulse product portfolio to an affiliate of Siris Capital, a private equity firm, for total consideration of $230.7 million, of which $105.7 million was in cash, net of a $19.3 million working capital adjustment, and $125.0 million was in the form of an 18-month non-contingent interest-bearing promissory note issued to the Company. On October 2, 2015, the Company and the issuer of the promissory note agreed to modify the original terms of the

61

Table of Contents

note to extend the maturity date from April 1, 2016 to December 31, 2018. Since approximately $125.0 million of the transaction consideration is in the form of a non-contingent seller promissory note, there is the risk that we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, by the buyer under the note. In the event that the promissory note is not repaid on the terms we contemplate, any collection or restructuring efforts we undertake may be costly and require significant time and attention from our management.

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 effectively implement improved systems and processes, our ability to manage our business, financial condition, and results of operations may be negatively affected.

Our products are highly technical and if they contain undetected defects, errors or malware or do not meet customer quality expectations, our business could be adversely affected, and we may be subject to additional costs or 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. For example, in December 2015, we disclosed that we identified unauthorized code in ScreenOS that could allow a knowledgeable attacker to gain administrative access to NetScreen devices and to decrypt VPN connections.

Any errors, defects, malware or security vulnerabilities discovered in our products after commercial release could result in monetary penalties, loss of revenues or delay in revenue recognition, loss of customers, loss of future business and reputation, penalties, and increased service and warranty cost, any of which could adversely affect our business, financial condition, and results of operations. Following the identification of the ScreenOS vulnerabilities, we launched an investigation into the matter, developed patched releases for the latest versions of ScreenOS and notified customers, all of which required significant time and attention from management and our employees. 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 or indemnification. 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 are not available on terms acceptable to us, our revenues and ability to develop and introduce new products could be adversely affected.

We integrate licensed third-party technology into certain of our products. From time to time, we may be required to license additional technology from third-parties to develop new products or product enhancements. Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. The failure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Some of our agreements with our licensors may be terminated for convenience by them. In addition, we cannot be certain that our licensors are not infringing the intellectual property rights of third parties or that our licensors have sufficient rights to the licensed intellectual property in all jurisdictions in which we may sell our products. 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, our business, financial condition, and results of operations could be adversely affected.

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

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

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to assess the effectiveness of our internal control over financial reporting and to disclose in our filing if such controls were unable to provide assurance that a material error would be prevented. We have an ongoing program to implement and test the system and process controls necessary to comply with these requirements. We have and will continue to incur significant expenses and devote management resources to Section 404 compliance. 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 regarding the reliability of our financial statements may be adversely affected which could cause a decline in the market price of our stock and otherwise negatively affect our liquidity and financial condition.

Failure to maintain our credit ratings could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.

The major credit rating agencies routinely evaluate our indebtedness. This evaluation is based on a number of factors, which include financial strength as well as transparency with rating agencies and timeliness of financial reporting. There can be no assurance that we will be able to maintain our credit ratings and failure to do so could adversely affect our cost of funds and related margins, liquidity, competitive position and access to capital markets.

We may be unable to generate the cash flow to satisfy our expenses, make anticipated capital expenditures or service our debt obligations, including the Senior Notes and the Revolving Credit Facility.

In February 2016, we issued $350.0 million aggregate principal amount of 3.125% senior notes due 2019, which we refer to as the 2019 Notes, and $150.0 million aggregate principal amount of 4.5% senior notes due 2024, which we refer to as the 2024 Notes. In March 2015, we issued $300.0 million aggregate principal amount of 3.30% senior notes due 2020, which we refer to as the 2020 Notes, and $300.0 million aggregate principal amount of 4.35% senior notes due 2025, which we refer to as the 2025 Notes.

Table of Contents

In addition, in March 2014, we issued $350.0 million aggregate principal amount of our 2024 Notes and in March 2011, we issued $1.0 billion aggregate principal amount of senior unsecured notes, which we refer to as the Senior Notes and together with the 2019 Notes, 2020 Notes, 2024 Notes and 2025 Notes, the Notes (see discussion in Note 8, Debt and Financing , in the Notes to Consolidated Financial Statements of this Report). As of March 31, 2016 , we had $2,131.8 million in outstanding long-term debt. In June 2014, we entered into a Credit Agreement with certain institutional lenders that provides for a five year $500.0 million unsecured revolving credit facility, which we refer to as the Revolving Credit Facility, with an option to increase the Revolving Credit Facility, up to a maximum of $700.0 million. The Credit Agreement will terminate in June 2019, at which point all amounts borrowed must be repaid. As of March 31, 2016 , no amounts were outstanding under the Credit Agreement.

We may not be able to generate sufficient cash flow to enable us to satisfy our expenses, make anticipated capital expenditures or service our indebtedness, including the Notes and the Revolving Credit Facility (if drawn upon). Our ability to pay our expenses, 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 at least the next twelve months to meet our anticipated requirements for working capital, capital expenditures and scheduled payments of principal and interest on our indebtedness, including the Notes and the Revolving Credit Facility (if drawn upon). 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 Notes), repatriate off-shore cash to the U.S. at unfavorable tax rates 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 indentures that govern the Notes contain various covenants that limit our ability and the ability of our subsidiaries to, among other things:

•	incur liens;	

•	incur sale and leaseback transactions; and	

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

The Credit Agreement contains two financial covenants along with customary affirmative and negative covenants that include the following:

•	maintenance of a leverage ratio no greater than 3.0x and an interest coverage ratio no less than 3.0x	

•	covenants that limit or restrict the ability of the Company and its subsidiaries to, among other things, grant liens, merge or consolidate, dispose of all or substantially all of its assets, change their accounting or reporting policies, change their business and incur subsidiary indebtedness, in each case subject to customary exceptions for a credit facility of this size and type.	

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 Notes, any notes issued in connection with the recently-announced capital return program discussed below and the Revolving Credit Facility (if drawn upon).

Our failure to pay quarterly dividends to our stockholders or the failure to meet our commitments to return capital to our stockholders could have a material adverse effect on our stock price.

In April 2016, we announced a cash dividend of $0.10 per share of common stock payable on June 22, 2016 to stockholders of record as of the close of business on June 1, 2016. Our ability to pay quarterly dividends will be subject to, among other things, our financial position and results of operations, available cash and cash flow, capital requirements and other factors. Any failure to pay or increase future dividends as announced, reduction or discontinuation of quarterly dividends could have a material adverse effect on our stock price.

64

Table of Contents

In addition, in July 2015 and October 2014, our Board of Directors authorized a $500.0 million and a $1.1 billion increase, respectively, to our current capital return plan. The capital return plan will be funded by a combination of onshore cash, previously issued debt and, potentially, additional debt financing, to preserve our financial flexibility to invest in future growth opportunities and maintain our investment grade credit rating. We intend to target a capital return policy of approximately 50% of annual free cash flow, inclusive of share repurchases and dividends, after completion of the $4.1 billion capital return program. Free cash flow is calculated as net cash provided by operating activities less capital expenditures. Any failure to meet our commitments to return capital to our shareholders could have a material adverse effect on our stock price.

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, 2016 , we had $1,646.0 million in cash and cash equivalents and $1,770.8 million in short- and long-term investments. We have invested these amounts primarily in asset-backed securities, certificates of deposit, commercial paper, corporate debt securities, foreign government debt securities, government- sponsored enterprise obligations, money market funds, mutual funds, publicly-traded equity securities, time deposits and U.S. government securities. Certain of these investments are subject to general credit, liquidity, market, sovereign debt, and interest rate risks. Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of our publicly traded debt or equity investments is judged to be other-than-temporary. These market risks associated with our investment portfolio may have a material adverse effect on our liquidity, financial condition, and results of operations.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the U.S. District Court for the District of Delaware) is the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of fiduciary duty owed by any of our current or former directors, officers, or other employees to us or to our stockholders; (iii) any action asserting a claim arising pursuant to the Delaware General Corporation Law, our restated certificate of incorporation, or our bylaws; (iv) any action or proceeding asserting a claim as to which Delaware General Corporation Law confers jurisdiction on the Court of Chancery or (v) any action asserting a claim governed by the internal affairs doctrine. The exclusive forum provisions in our bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our current or former directors, officers, or other employees, which may discourage such lawsuits against us and our current or former directors, officers, and other employees. Alternatively, if a court were to find the exclusive forum provisions contained in our bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material and adverse impact on our business.

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.
