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 U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The Condensed Consolidated Balance Sheet as of December 31, 2016,2017 has been derived from the audited Consolidated Financial Statements at that date. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three and six months ended June 30, 2017,2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017,2018, 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, 20162017 (the "Form 10-K").

Excess tax benefits from share-based compensation in prior periods haveThe Company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2016-18 (Topic 230) Statement of Cash Flow: Restricted Cash, effective January 1, 2018, using the retrospective transition method. Restricted cash of $47.4 million and $48.7 million has been reclassifiedincluded within cash, cash equivalents and restricted cash when reconciling the beginning and ending total amounts, respectively, on the statement of cash flows for the six months ended June 30, 2017, to conform to the current-period presentation incurrent period presentation. The adoption did not have a material impact on the cash flow activity presented on the Company's Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2017. See Note 3, Cash Equivalents and Investments for a reconciliation of the cash balances within our Condensed Consolidated Statements of Cash Flows upon adoption ofto the accounting standard described in Note 2, Summary of Significant Accounting Policies.Condensed Consolidated Balance Sheets.

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

Except for the change in certain policies related to share-based compensation upon adoption of the accounting standardstandards described below, 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 Form 10-K.

Recently Adopted Accounting Standard

OnComprehensive Income: Effective January 1, 2017,2018, the Company early adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU")FASB ASU No. 2016-092018-02 (Topic 718)220), Compensation—Stock Compensation: Improvements to Employee Share-Based Payment AccountingIncome Statement - Reporting Comprehensive Income, which simplifies several aspectsissued in February 2018, with an election to reclassify stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (the "Tax Act"), from accumulated other comprehensive income to retained earnings. The adoption resulted in a reclassification of the accounting for share-based payment transactions, including the$5.7 million in income tax consequences, classification of awardsfrom accumulated other comprehensive income (loss) to accumulated deficit as either equity or liabilities, forfeiture, statutory tax withholding requirements, and classification on the statement of cash flows. The impact of the adoption ondate. The comparative information has not been restated and continues to be reported under the Company's condensed consolidated financial statements was as follows:accounting standards in effect for those periods.

Forfeitures: The Company elected to account for forfeitures as they occur using a modified retrospective transition method,rather than estimating forfeitures, resulting in a cumulative-effect adjustment of $9.0 million, which increased the January 1, 2017 opening accumulated deficit balance on the Condensed Consolidated Balance Sheets.
Income tax accounting: The Company is also required to record excess tax benefits and tax deficiencies related to stock- based compensation as income tax benefit or expense in the statement of operations prospectively when share-based awards vest or are settled. Upon adoption, the Company recognized the previously unrecognized excess tax benefits using the modified retrospective transition method, which resulted in no impact to the January 1, 2017 opening accumulated deficit balance as previously unrecognized excess tax effects were fully offset by a valuation allowance.
Cash flow presentation of excess tax benefits: The Company is required to classify excess tax benefits along with other income tax cash flows as an operating activity either prospectively or retrospectively. The Company elected to apply the change in presentation to the statements of cash flows retrospectively and no longer classify the excess tax benefits from share-based compensation as a financing activity. For the six months ended June 30, 2016, the Company reclassified $5.6 million of excess tax benefits from share-based compensation to operating activities from financing activities.

Financial Instruments: On January 1, 2018, the Company adopted FASB ASU No. 2016-01, Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilitiesand FASB ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall, which changes how entities classify and measure equity investments and present changes in the fair value of financial liabilities measured under the fair value option. The guidance also updates certain presentation and disclosure requirements. The Company adopted ASU 2016-01 as of January 1, 2018 using the modified retrospective method for its equity securities with readily determinable fair values and the prospective method for its equity securities without readily determinable fair values, resulting in no impact to the opening accumulated deficit balance. The Company has elected to use the measurement alternative for its equity investments without readily determinable fair value, defined as cost adjusted for changes from observable transactions for identical or similar investments of the same issuer, less impairment. See Note 3, Cash Equivalents and Investments for additional disclosures required upon adopting the standard.

Revenue Recognition: On January 1, 2018, the Company adopted FASB ASU No. 2014-09 (Topic 606) - Revenue from Contracts with Customers (“ASU 2014-09” or "Topic 606"), which provides guidance for revenue recognition that superseded the revenue recognition requirements in Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition ("Topic 605") and most industry specific guidance. Under ASU 2014-09, 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. The Company adopted ASU 2014-09 under the modified retrospective approach, applying the amendments to prospective reporting periods. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the historic accounting under Topic 605.
The cumulative effect of the changes made to our Condensed Consolidated Balance Sheet as of January 1, 2018 for the adoption of Topic 606 to all contracts with customers that were not completed as of December 31, 2017 was recorded as an adjustment to accumulated deficit as of the adoption date as follows:

Includes additional adjustments identified subsequent to the filing of the Form 10-Q for the three months ended March 31, 2018, which were not material to such previously issued financial statements.

Upon adoption, the Company recorded a cumulative effect adjustment of $324.7 million, net of tax adjustment of $63.9 million, which decreased the January 1, 2018 opening accumulated deficit balance on the Condensed Consolidated Balance Sheet, primarily as a result of the following items:

Distributor Sales: Under Topic 606, the Company recognizes revenue from sales to distributors upon delivery of the product to the distributor, rather than upon delivery of the product to the end customer. Rebates and incentives offered to distributors, which are earned when sales to end customers are completed, are estimated at the point of revenue recognition.

Software Revenue: Under Topic 605, the Company deferred revenue for software licenses where vendor-specific objective evidence ("VSOE") of fair value had not been established for undelivered items (primarily services). Under Topic 606, revenue for software licenses is recognized at the time of delivery unless the ongoing services provide frequent, critical updates to the software, without which the software functionality would be rapidly diminished.

Variable Consideration: Some of the Company's contracts include penalties, extended payment terms, acceptance provisions or other price variability that precluded revenue recognition under Topic 605 because of the requirement for amounts to be fixed or determinable. Topic 606 requires the Company to estimate and account for variable consideration as a reduction of the transaction price.
Revenue Allocation: Similar to Topic 605, Topic 606 requires an allocation of revenue between deliverables, or performance obligations, within an arrangement. Topic 605 restricted the allocation of revenue that is contingent on future deliverables to current deliverables; however, Topic 606 removes this restriction. In addition, the nature of the performance obligations identified within a contract under Topic 606 as compared to Topic 605 will impact the allocation of the transaction price between product and services.

Contract Acquisition Costs: Topic 606 requires the deferral and amortization of “incremental” costs incurred to obtain a contract where the associated contract duration is greater than one year. The primary contract acquisition cost for the Company are sales commissions. Prior to January 1, 2018, the Company expensed sales commissions. The change required by Topic 606 resulted in the creation of an asset on January 1, 2018.

The impact of adoption of Topic 606 on the Company's Condensed Consolidated Statements of Operations and Condensed Consolidated Balance Sheet was as follows (in millions):

Revenue Recognition

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 by following a five-step process, (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below.

Identify the contract with a customer. The Company generally considers a sales contract or agreement with an approved purchase order as a customer contract provided that collection is considered probable, which is assessed based on the creditworthiness of the customer as determined by credit checks, payment histories, and/or other circumstances. The Company combines contracts with a customer if contracts are negotiated with a single commercial substance or contain price dependencies.

Identify the performance obligations in the contract. Product performance obligations include hardware and software licenses and service performance obligations include maintenance, software post-contract support, training, and professional services. Certain software licenses and related post-contract support are combined into a single performance obligation when the maintenance updates are critical to the continued functionality of the software.

Determine the transaction price. The transaction price for the Company’s contracts with its customers consists of both fixed and variable consideration provided it is probable that a significant reversal of revenue will not occur when the uncertainty related to variable consideration is resolved. Fixed consideration includes amounts to be contractually billed to the customer while variable consideration includes estimates for rights of return, rebates, and price protection, which are based on historical sales returns and price protection credits, specific criteria outlined in rebate agreements, and other factors known at the time. The Company generally invoices customers for hardware, software licenses and related maintenance arrangements at time of delivery, and professional services either upfront or upon meeting certain milestones. Customer invoices are generally due within 30 to 90 days after issuance. The Company’s contracts with customers typically do not include significant financing components as the period between the transfer of performance obligations and timing of payment are generally within one year.

Allocate the transaction price to the performance obligations in the contract. For contracts that contain multiple performance obligations, the Company allocates the transaction price to the performance obligations on a relative standalone selling price basis. Standalone selling prices are based on multiple factors including, but not limited to historical discounting trends for products and services, pricing practices in different geographies and through different sales channels, gross margin objectives, internal costs, competitor pricing strategies, and industry technology lifecycles.

Recognize revenue when or as the Company satisfies a performance obligation. Revenue for hardware and certain software licenses, are recognized at a point in time, which is generally upon shipment or delivery. Certain software licenses combined with post-contract support are recognized over time on a ratable basis over the term of the license. Revenue for maintenance and software post-contract support is recognized over time on a ratable basis over the contract term. Revenue from training and professional services is recognized over time as services are completed or ratably over the contractual period of generally one year or less.

Deferred Commissions

Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and then amortized over a period of benefit which is typically over the term of the customer contracts as initial commission rates and renewal rates are the same. Amortization expense is included in sales and marketing expenses in the accompanying Condensed Consolidated Statements of Operations.

Recent Accounting Standards Not Yet Effective

Derivatives and Hedging: In MayAugust 2017, the FASB issued ASU No. 2017-092017-12 (Topic 718)815) Compensation—Stock Compensation: Scope of ModificationDerivatives and Hedging — Targeted Improvements to Accounting for Hedging Activities, which provides guidance onexpands an entity's ability to hedge financial and nonfinancial risk components and amends how companies assess effectiveness as well as changes the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting.presentation and disclosure requirements. The new standard is effectiveto be applied on a prospectivemodified retrospective basis and is effective for interim and annual periods beginning after December 15, 2017,2018, with early adoption permitted. . The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements.

Amortization on Purchased Callable Debt Securities:In March 2017, the FASB issued ASU No. 2017-08 Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities which shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. The ASU will not impact debt securities held at a discount. This standard is effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods, and is to be applied on a modified retrospective basis with early adoption permitted. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements.

In February 2017,Simplifying the FASB issued ASU No. 2017-05Test for Goodwill Impairment: Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which amends guidance on how entities account for the derecognition of a nonfinancial asset or an in substance nonfinancial asset that is not a business. This standard is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods, and is to be applied on either a retrospective or modified retrospective basis with early adoption permitted. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements.

In January 2017, the FASB issued ASU No. 2017-04 (Topic 350) Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment, which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will now be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. This guidanceASU will be applied on a prospective basis and is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted for any impairment tests performed after January 1, 2017.

In January 2017, the FASB issued ASU No. 2017-01 (Topic 805)Credit Losses on Financial Instruments: Business Combinations: Clarifying the Definition of a Business, which clarifies the definition of a business and assists entities with evaluating when a set of transferred assets and activities is a business. This ASU is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted.

In November 2016, the FASB issued ASU No. 2016-18 (Topic 230) Statement of Cash Flow: Restricted Cash, which provides guidance on the classification of restricted cash to be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts on the statement of cash flows. The amendments of this ASU are effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The standard must be applied retrospectively to all periods presented. The Company does not anticipate that the adoption of this standard will have a material impact on the cash flow activity presented on its Consolidated Statements of Cash Flows.

In October 2016, the FASB issued ASU No. 2016-16 (Topic 740) Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory, which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 will be effective for annual and interim reporting periods beginning after December 15, 2017 and is to be applied on a modified retrospective basis. Early adoption is permitted. The Company does not anticipate that the adoption of this standard will have a material impact on the Consolidated Financial Statements.

In August 2016, the FASB issued ASU No. 2016-15 (Topic 230) Statement of Cash Flow: Classification of Certain Cash Receipts and Cash Payments, which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. This pronouncement is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company does not anticipate that the adoption of this standard will have a material impact on its Consolidated Statements of Cash Flows.

In June 2016, the FASB issued ASU No. 2016-13 (Topic 326) Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments, which provides more decision-useful information about the expected credit losses on financial instruments and changes the loss impairment methodology. This pronouncement is effective for reporting periods beginning after December 15, 2019, and interim periods within those fiscal years, using a modified retrospective adoption method. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its Consolidated Financial Statements and disclosures.

Leases:In February 2016, the FASB issued ASU No. 2016-02 (Topic 842), Leases, which requires recognition of lease assets and lease liabilities on the balance sheet by lessees for leases classified as operating leases with a lease term of more than twelve months.under current GAAP. This ASU shouldmust 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 intends to adopt this standard effective January 1, 2019, and is currently evaluatingon schedule to complete its evaluation of the impact of adoption of this standardto its financial statements, disclosures, processes, systems and has commenced the assessment phase to determine the approach for implementing this standard. The adoption of this standard is expected to havecontrols. We currently anticipate a material impact related to the recognition of lease assets and lease liabilities for previously unrecognized leases on the Company'sour Consolidated Balance Sheets, and disclosures. The Company is still evaluatingwe are continuing to evaluate the impact this standard will have on the Consolidated Statements of Operations.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, which changes how entities measure equity investments and present changes in the fair value of financial liabilities measured under the fair value option. The guidance also updates certain presentation and disclosure requirements. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact this standard will have on its Consolidated Financial Statements and disclosures.
In May 2014, the FASB issued ASU No. 2014-09 (Topic 606)—Revenue from Contracts with Customers and several amendments thereafter (“ASU 2014-09”), which provides guidance for revenue recognition that will supersede the revenue recognition requirements in Topic 605, and most industry specific guidance. The core principle for ASU 2014-09 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. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017.

The Company intends to adopt ASU 2014-09 on January 1, 2018 retrospectively, applying the amendments to each prior reporting period presented and currently remains on schedule with its implementation and the preparation of its prior-period financial statements.

Upon adoption, the Company expects a material impact to the opening balance sheet as of January 1, 2016 related to the cumulative effect of adopting this standard, primarily due to the application of the new guidance in the areas of distributor sales, software revenue, contract acquisition costs, variable consideration, and revenue allocation. The Company continues to assess the impact of ASU 2014-09 including any changes to systems, processes and the control environment as it works through the adoption in 2017, and there remain areas still to be fully concluded upon. In addition, there are ongoing interpretive reviews, which may alter the Company's conclusions on key accounting assessments and the financial impact of ASU 2014-09 on the Company's Consolidated Financial Statements. For further information, refer to Note 2, Significant Accounting Policies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Form 10-K.

The Company's Level 2 available-for-sale fixed incomedebt 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 and six months ended June 30, 2017,2018, 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 lack of observable inputs to determine fair value. The Company estimates the fair value of its privately-held debt and redeemable preferred stock securities 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 and six months ended June 30, 2017,2018, there were no purchases, sales, gains, or lossessignificant activities related to privately-held debt and redeemable preferred stocks securities.

AsCertain of June 30, 2017, the Company had noCompany's assets, required to be measured at fair value on a nonrecurring basis. Investments in privately-held companies, which are normally carried at cost,including intangible assets and goodwill are measured at fair value on a nonrecurring basis, duewhen they are deemed to eventsbe other-than temporarily impaired. There were no impairment charges recognized during the three and circumstances that the Company identifies as materially impacting the carrying value of the investments. As of December 31, 2016, certainsix months ended June 30, 2018.

Equity investments in privately-held companies with a carrying value of $1.6 million were impaired and written-down to theirwithout readily determinable fair value of zero and were classified as Level 3 assets due to lack of observable inputs to determine fair value. The Company estimates theare measured at fair value, of itswhen they are deemed to be impaired or when there is an adjustment from observable price changes. For the three and six months ended June 30, 2018, there were no impairment charges or adjustments resulting from observable price changes for equity investments in privately-held companies using an analysis of the financial condition and near-term prospects of the investee, including recent financing activities and the investee's capital structure.

As of June 30, 20172018 and December 31, 2016,2017, the Company had no liabilities required to be 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, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. As of June 30, 20172018 and December 31, 2016,2017, the estimated fair value of the Company's short-term and long-term debt in the Condensed Consolidated Balance Sheets was $2,277.3$2,178.8 million and $2,215.7$2,252.9 million, respectively, based on observable market inputs (Level 2). The carrying value of the promissory note issued to the Company in connection with the previously completed sale of Junos Pulse (the “Pulse Note”), of $58.5$64.6 million and $132.9$61.2 million approximates its fair value as of June 30, 20172018 and December 31, 2016.2017, respectively. The Pulse Note is classified as a Level 3 asset due to the lack of observable inputs to determine fair value. See Note 7, Other Financial Information, for further information on the Pulse Note.

The Company's effective tax rates during the three and six months ended June 30, 2017 and June 30, 2016, differ from the statutory rate primarily due to the benefit of the Section 199 deduction for U.S. production activities, the federal research and development credit, and earnings in foreign jurisdictions, which are subject to lower tax rates. Additionally, the Company's effective tax rates for the three and sixmonths ended June 30, 2017 were also impacted by the benefit from restructuring charges and excess tax benefits related to share-based compensation.

As of June 30, 2017, the total amount of gross unrecognized tax benefits was $235.0 million, of which $202.7 million, if recognized, would favorably affect the Company's effective tax rate.

Note 11. Income Taxes

Effective tax rate22.8% 26.7% 21.5% 25.2%

The Tax Act enacted in December 22, 2017 introduced significant changes to U.S. income tax law. Effective January 1, 2018, the Tax Act reduced the U.S. federal corporate income tax rate from 35% to 21% and created a minimum tax on foreign earnings.

Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, the Company made reasonable estimates of the effects and recorded provisional amounts in the financial statements as of December 31, 2017. As the Company collects and prepares the necessary data, interprets the Tax Act and reviews any additional guidance issued by the U.S. Treasury Department, state revenue and taxation authorities and other standard-setting bodies, the Company may make adjustments to the provisional amounts which may materially impact its provision for income taxes from continuing operations in the period in which the adjustments are made. The adjustments made during the three and six months ended June 30, 2018, were not material. The accounting for the tax effects of the Tax Act will be completed later in 2018.

The Tax Act also includes provisions to tax Global Intangible Low-Taxed Income (“GILTI”) of foreign subsidiaries in excess of a deemed return on their tangible assets. Due to the complexities of the new provisions, the Company is continuing to evaluate how the provisions will be accounted for under U.S. GAAP. Pursuant to the Tax Act, corporations are allowed to make an accounting policy election to either (i) account for GILTI as a component of income tax expense in the period in which the corporation is subject to the rules (the “period cost method”), or (ii) account for GILTI in the corporation's measurement of deferred taxes (the “deferred method”). The Company has not currently elected a method and will do so after completing its analysis of the GILTI provisions of the Tax Act depending on the analysis of the Company’s global income. Therefore, the Company has not recorded any potential deferred tax effects related to the GILTI in its financial statements and has no policy election regarding whether to record deferred taxes on GILTI or use the period cost method. The Company has, however, included an estimate of the current GILTI impact in its annual effective tax rate for 2018. The Company expects to complete the accounting during the measurement period.

The Company's effective tax rate during the three and six months ended June 30, 2018 differs from the statutory rate of 21%, primarily due to less favorable mix of foreign earnings taxed at varying rates, and state income tax, offset by the benefit of the federal research and development credit.

As of June 30, 2018, the total amount of gross unrecognized tax benefits was $261.7 million.

The Company engages in continuous discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. It is reasonably possible that the balance of unrecognized tax benefits could decrease up to $50 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 balance primarily relates to matters involving U.S. and non-U.S. taxation of cross-border transactions and the utilization of losses.

Note 15.13. Commitments and Contingencies

Commitments

Except for the items below, there have been no material changes to the Company's commitments compared to the commitments described in Note 16, Commitments and Contingencies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Form 10-K.

Clock-Signal, Supplier Component Remediation LiabilityPurchase Commitments with Contract Manufacturers and Suppliers

In order to reduce manufacturing lead times and in the interest of having access to 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 $609.4 million as of June 30, 2018.

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 June 30, 2017 and December 31, 2016,2018, the Company had approximately $6.8accrued $24.1 million and $10.8 million, respectively, in other accrued liabilitiesbased on the Condensed Consolidated Balance Sheets for the expected remediation costs for certain products containing a defect in a clock-signal component manufactured by a third-party supplier. The Company has been advised by the component supplier that components may begin to fail after the product has been in operation for 18 months. The Company has commenced the process with its customers to implement the remediation.estimate of such charges.

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 June 30, 20172018 and December 31, 2016,2017, the Company recorded $14.8$9.4 million and $28.9$20.4 million, respectively, for such indemnification obligations in other accrued liabilities and other long-term liabilities on the Condensed Consolidated Balance Sheets. During the six months ended June 30, 2017, $15.0 million of indemnification obligations expired and were therefore released.

Legal Proceedings

Investigations

The Company previously disclosed that it has been the subject of investigations by 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 cooperatingIn cooperation with these agencies regarding these matters. The Company’sinvestigations, the Company and the Audit Committee of the Board of Directors, with the assistance of outside counsel and other independent advisors, has been investigating and conductingconducted a thorough reviewinternal investigation. As a result of possible violations of the FCPA, and has made recommendations for remedial measures, including employee disciplinary actions in foreign jurisdictions, whichits internal investigation, the Company made significant improvements in its internal controls and carried out a number of disciplinary actions. In the fourth quarter of 2017, the DOJ notified the Company that the DOJ has implemented and continuesclosed its investigation related to implement.these matters without taking any action against the Company. The Company is unablecontinuing to predictfully cooperate with the duration, scope or outcome of the SEC and DOJ investigations,SEC’s ongoing investigation, but believes that an adverse outcome is reasonably possible. However,Based on the Company’s recent communications with the Staff of the SEC, the Company believes that it is likely that the Staff of the SEC will seek to bring an enforcement action against the Company. As a result, the Company believes it is reasonably possible that it could incur a loss related to the ongoing SEC investigation, but the Company is not able to estimate the outcome or develop a reasonable estimate of a possible loss or range of possible loss. The SEC and/or DOJ could take action againstlosses, if any. As discussions are continuing, there can be no assurance as to the Companytiming 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.terms of any final resolution of this matter.

Other Litigations and Investigations

In addition to the investigations discussed above, the Company is involved in other investigations, disputes, litigations, and legal proceedings. 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 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.

Our products are sold in three geographic regions: Americas; Europe, Middle East, and Africa, or EMEA; and Asia Pacific, or APAC. We sell our high-performance network products and service offerings across routing, switching, and security.security technologies. In addition to our products, we offer our customers worldwide services, including technicalmaintenance and support, professional services, and education and training programs. We believe 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.

Further, our intent is to lead in the area of software solutions that simplify the operation of networks, and to allow our customers across our key verticals to deliver further value overthrough their networks. We anticipate that our increased focus on software business models will result in an increase in software revenuerevenues as a percentage of total revenuerevenues over time.

In the first quarter of 2017,2018, we began reporting revenue onrevised the followingnaming convention of our key customer verticals: Cloud, verticals as follows:

Telecom/Cable and will now be referred to as ‘Service Provider’
Strategic Enterprise which we believe better aligns with our business model comparedwill now be referred to our previous reporting of revenue by Service Provider and Enterprise. A summary of the typesas ‘Enterprise’
Cloud will remain unchanged

Types of customers included in ourthe key customer verticals is as follows:

Cloud: companies that are heavily reliant on the cloud for their business model’s success. As an example, customers in the cloud vertical can include cloud service providers as well as enterprises that provide software-as-a-service, infrastructure-as-a-service, or platform-as-a-service.

Telecom/Cable: includes wireline and wireless carriers and cable operators.will remain unchanged.


Strategic Enterprise: generally is comprised of financial services; national, federal, state,We are focused on and local governments; research and educational institutions, and enterprises not represented in the Cloud vertical.

We continue to see significant opportunities from the shift towards theimplementation of cloud which we generally viewarchitectures, such as large public and private data centers. The trend towardscenters, as well as distributed cloud infrastructure, which resides in multiple, distributed data centers in order to place applications or services closer to end users, such as enabling security and "network-as-a-service."

We believe the network needs for our customers in our Service Provider, Cloud and Enterprise verticals are converging, as these customers recognize the need for high performance networks and leveraging the cloud for improved agility and greater levels of operating efficiency.

As these customers continue to grow, we believe their network architectures is a focus area of our strategy and wewill continue to evolve. We believe our understanding of high performance networking technology positionsand our strategy position us to capitalize on thisthe industry transition.transition to more automated, cost-efficient, scalable networks.

In routing, we believe that certain large Cloud customers are transitioning their wide area networks from a scale-up to a scale-out architecture as they continue to add capacity. This has resulted in, and we expect this may continue to result in, a transition of these customers from purchasing our MX product family to our PTX product family. These architectural shifts have led to a near-term slowdown in our net revenues as in some cases there is a pause before the new architecture ramps.

In switching, we see that certain large Cloud customers who can rapidly scale based on increased demand, are in the process of adopting 100-Gigabit connections, or 100G, resulting in certain large deployment delays at our largest Cloud customers as they prepare for this adoption. 

Despite these ongoing deployment delays and architectural shifts, we remain confident in our competitive position and strong relationships with these strategic customers. Our overall strategy with our Cloud customers has not changed and we continue to execute against our innovation roadmap, which includes our plan to continue to grow our relevance and our business in the Cloud vertical.

During the second quarter of 2017,2018, we continued to execute on our product strategy. We announced Cloud-Grade Networking to accelerate agility and innovation instrategy, specifically around the Cloud. Cloud-Grade Networking builds on carrier-grade reach and reliability and enterprise-grade control and usability, bringing cloud-level agility and operational scale to networks everywhere. This announcement includes two new foundational products:
Junos Node Slicing: converges multiple concurrent network functions on the same physical routing infrastructure, letting customers optimize their infrastructure while offering differentiated services with enhanced operational and administrative isolation within a single chassis.
Universal Chassis: a breakthrough system allowing customers to standardize on a hardware platform across their data center, core, and network edge. We believe the system will create significant valuealso simplified threat response for our customers by enhancing their return on investment through reduced costs.
In Security, we announcedwith enhancements to our Software Defined Secure Networks, or SDSN, platformUnified Cybersecurity Platform that includes integrations between SRX Series Next-Generation Firewalls, the Advanced Threat Prevention (ATP) Appliance, and expanded our public cloud offeringJuniper ATP Appliance integrations with the introduction of vSRX for Azure. Our SDSN enhancements deliver pervasive security across multi-vendor environments, public clouds, and private clouds.Junos Space Security Director Policy Enforcer.

Net Revenues: Net revenues increaseddecreased during the three and six months ended June 30, 2017,2018, compared to the same periods in 2016,2017, primarily driven by the Cloud vertical as well as strong switching revenue growth as we saw continued data center strength, particularly from our QFX product family. We also saw year-over-year growth during the three and six months ended June 30, 2017, compared to the same periods in 2016, from our Services business due to strong attach rateslower routing and renewals of support contracts. The year-over-year revenue growth was primarily from the Americas and APAC.

switching revenues, offset by an increase in security revenue. Of our top ten customers for the second quarter of 2017, four2018, six were Cloud, fivethree were Telecom/Cable, andService Provider, one was a Strategic Enterprise. Of these customers, twoEnterprise, and all of them were located outside ofwithin the U.S.

For the three and six months ended June 30, 2018, the adoption of Topic 606 resulted in a decrease in revenue recognition of $16.8 million and $14.9 million, respectively, due to lower service revenue, partly offset by product revenue. Product revenues during the three and six months ended June 30, 2018 were higher by $29.2 million and $57.9 million, respectively, under Topic 606, compared to Topic 605, primarily due to the impact of revenue allocation between products and services, timing of revenue recognition from sales to distributors and variable consideration. The product revenue increase from Topic 606 was allocated among all product categories. Service revenues during the three and six months ended June 30, 2018 were lower by $46.0 million and $72.8 million, respectively, under Topic 606, compared to Topic 605, primarily due to the impact of revenue allocation between products and services, and due to certain contractual clauses. The adoption of Topic 606 will impact the allocation of revenues between product and service; however, we continue to expect there will not be a material difference in total annual revenue. See Note 2, Summary of Significant Accounting Policies, in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part 1 of this report, for further discussion on the adoption of Topic 606.

Gross Margin: Our gross margin as a percentage of net revenues decreased during the three and six months ended June 30, 2017,2018, compared to the same periods in 2016,2017, primarily due to (i)lower revenues, customer mix, as we continue to expand our footprint with certain strategic customers, particularly in the Cloud and Telecom/Cable verticals in APAC; (ii) product mix related to the strong performance of Switching; and (iii) higher costs of certain memory components. The decrease wascomponents, partially offset by improvements in our cost structure and higher net revenues. Additionally, our gross margin as a percentage of net revenues for the six month ended June 30, 2017, compared to the same period in 2016, was impacted by charges related to certain supplier component remediation.structure.


Operating Margin: Our operating income as a percentage of net revenues increaseddecreased during the three and six months ended June 30, 2017,2018, compared to the same periods in 2016,2017, primarily due to higher net revenues driven by strength in our Switching and Services business, as well as a decrease in operating expenses primarily driven by lower share-based compensation expense during the three month ended June 30, 2017. This was partially offset by higher costs of revenues asdrivers described in the gross margin discussion above.above, partially offset by a net decrease in our operating expenses from restructuring charges during the second half of 2017 that we did not incur during the same period in 2018.

Capital Return: We continueDuring the three months ended March 31, 2018, we entered into an accelerated share repurchase program (the "ASR") to return capital topurchase an aggregate of $750.0 million in shares. Under the ASR, we made an upfront payment of $750.0 million and received an initial delivery of 23.3 million shares for an aggregate price of $600.0 million. No repurchases of our stockholders.common stock were made during the three months ended June 30, 2018. Upon completion of the ASR in the third quarter of 2018, we received an additional 6.0 million shares from the financial institutions. These 6.0 million shares will be retired in the third quarter of 2018. The completion of the ASR resulted in a total settlement of 29.3 million shares of our common stock at a volume weighted average repurchase price, less an agreed upon discount, of $25.62 per share. During the three and six months ended June 30, 2017,2018, we repurchased 4.0 million and 8.5 million of shares of our common stock, respectively, andalso paid a quarterly cash dividend of $0.10$0.18 per share, for an aggregate amount of $37.8$62.8 million and $75.8$124.9 million, respectively.

Operating Cash FlowFlows:s: Operating Net cash flows increasedprovided by operations decreased during the six months ended June 30, 2017,2018, compared to the same period in 2016,2017. The decrease was primarily due to higher cash collections from customers partially offset byduring the first six months of 2017 related to service renewals invoiced during the fourth quarter of 2016, and an increase in cash paid during 2018 for income taxes, primarily due to the first of eight annual transition tax payments related to the Tax Act. These decreases in cash flows were offset by a decline in cash paid for personnel-related expenses.costs, principally as a result of a reduction in headcount and lower 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 second quarter of 2017 decreased,2018 was flat, compared to the same period in 2016. DSO during the second quarter of 2016 was higher due to the ERP implementation transition experienced during that period.2017.

Product deferred revenue:Deferred Revenue: ProductTotal deferred revenue decreased as of June 30, 20172018, compared to December 31, 2016, primarily2017, due to the recognitionimpact of previously deferred revenue related to the completionadoption of delivery to an APAC Telecom customer Topic 606. See Note 2, Summary of Significant Accounting Policies, in the first quarterNotes to Condensed Consolidated Financial Statements in Item 1 of 2017.Part 1 of this report, for further discussion on the adoption of Topic 606.


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 statementsCondensed 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, revenues, and expenses that are not readily apparent from other sources.

During the six months ended June 30, 2017,2018, except for the change in accounting estimates related to adoption of Topic 606 described below and changes in certain accounting policies described in Note 2, Summary of Significant Accounting Policies in the Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report, there were no other material 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 Form 10-K.

Revenue Recognition: We enter into contracts to sell our products and services, and while some of our sales agreements contain standard terms and conditions, there are agreements that contain non-standard terms and conditions and include promises to transfer multiple goods or services. As a result, significant interpretation and judgment is sometimes required to determine the appropriate accounting for these transactions including: (1) whether performance obligations are considered distinct that should be accounted for separately versus together and how the price should be allocated among the performance obligations and when to recognize revenue for each performance obligation; (2) developing an estimate of the stand-alone selling price ("SSP") of each distinct performance obligation; (3) combining contracts that may impact the allocation of the transaction price between product and services; and (4) estimating and accounting for variable consideration, including rights of return, rebates, price protection, expected penalties or other price concessions as a reduction of the transaction price.

Our estimates of SSP for each performance obligation requires judgment that considers multiple factors, including, but not limited to, historical discounting trends for products and services, pricing practices in different geographies and through different sales channels, gross margin objectives, internal costs, competitor pricing strategies, and industry technology lifecycles. Our estimates for rights of return, rebates, and price protection are based on historical sales returns and price protection credits, specific criteria

outlined in customer contracts or rebate agreements, and other factors known at the time. Our estimates for expected penalties and other price concessions are based on historical trends and expectations regarding future incurrence.

Changes in judgments with respect to these assumptions and estimates could impact the timing or amount of revenue recognition.

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 the recently adopted accounting standard and recent accounting standards not yet effective, 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.

Three Months Ended June 30, 20172018 compared with the Three Months Ended June 30, 20162017

Product net revenues increaseddecreased during the three months ended June 30, 2017,2018, compared to the same period in 2016, primarily2017, due to an increasea decrease in switching net revenues from our QFX product family, which sawrouting and switching products, partially offset by the impact of the adoption of Topic 606 and growth in the cloud data center driven by migration towards 100GbE infrastructure and as our customers adopt end-to-end solutions with our top-of-rack and spine data switching portfolio. Switching net revenues increased year-over-year across all verticals and in both the Americas and APAC. We expect that our data center switching portfolio will continue to drive revenue growth in our switching business in the foreseeable future.security.

The year-over-year increasedecrease in product netrouting revenues was primarily driven by Cloud, due to the ongoing architectural shifts in the Americas, partially offset by the impact of adoption of Topic 606.

Productimpact of Topic 606, our service net revenues increased during the six months ended June 30, 2017, compared to the same period in 2016, primarily due to continued data center strength in switching, particularly from our QFX product family. The switching net revenue growth was driven by the Cloud vertical in the Americas. We expect that our data center switching portfolio will continue to drive revenue growth in our switching business in the foreseeable future.

To a lesser extent, we saw an increase in routing revenues, primarily from our PTX and MX products, which were driven by Cloud customers in the Americas as well as Telecom/Cable customers in APAC as we expand our footprint with certain strategic customers. We experienced a continued decline in revenues from our security business, primarily due to our transition from legacy products to newer product offerings and we expect this transition to continue over the next few quarters.

Product gross margin

Product gross margin as a percentage of product revenues decreased during the three months ended June 30, 2017,2018, compared to the same period in 2016,2017, primarily due to (i) customer mix, as we continue to expand our footprint with certain strategic customers, particularly in the Cloud and Telecom/Cable verticals in APAC; (ii) product mix, related to the strong performance of Switching; and (iii) higher costs of certain memory components. The decreaselower revenues. This was partially offset by improvements in our cost structure and higher net revenues.

We expect similar gross margin dynamics to persist for the remainder of 2017 as seen in the first half of the year. We expect that our product gross margin will continue to vary in the future due to the mix of products sold and competitive pricing pressures. We believe product gross margins as a percentage of net revenues will improve over the long term from the continued expected acceptance of our new products and technologies, the expected increase in software revenues as a percentage of total revenues as we continue to focus on our software-based business models, and as we continue to manage costs within our supply chain.structure.

Three Months Ended June 30, 20172018 compared with the Three Months Ended June 30, 20162017

During the three months ended June 30, 2017,2018, compared to the same period in 2016,2017, total operating expenses decreased primarily due the lack of restructuring charges incurred during the second quarter of 2018, compared to the restructuring initiatives implemented under the 2017 Restructuring Plan during the same quarter last year. The decrease was offset by higher share-based compensation expense from certain performance share awards. Excluding the impact of share-based compensation and restructuring, total operating expenses decreased primarily due to lowera decline in personnel-related expenses, specifically share-based and variable compensation in research and development, or R&D, as well asresulting from lower headcount driven by restructuring initiatives during the first quarter of 2017. This was partially offset by higher costs related to business combinations completed in the second half of 2016 and an increase in engineering costs as a result of an increase in prototype development expenses. In addition, we recorded $8.0 million in charges during the three months ended June 30, 2017 as a result of the restructuring plan initiated in the first quarter of 2017 to realign our workforce and increase operational efficiencies, which we refer to as the 2017 Restructuring Plan. Restructuring charges recorded during the three months ended June 30, 2016 were related to business combinations. We continue to assess the performance of our operating results, against

our long-term operating goals and evaluate potential opportunities to improve our execution. As such, the 2017 Restructuring Plan could be expanded and additional restructuring charges may be incurred.

The effectiveTax Act enacted on December 22, 2017, introduced significant changes to U.S. income tax law. Effective January 1, 2018, the Tax Act reduced the U.S. federal corporate income tax rate decreased duringfrom 35% to 21% and created a minimum tax on foreign earnings.

Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, we made reasonable estimates of the effects and recorded provisional amounts in the financial statements as of December 31, 2017. As we collect and prepare the necessary data, interpret the Tax Act, and review any additional guidance issued by the U.S. Treasury Department, state revenue and taxation authorities, and other standard-setting bodies, we may make adjustments to the provisional amounts, which may materially impact our provision for income taxes from continuing operations in the period in which the adjustments are made. During the three and six months ended June 30, 2017, compared2018, the adjustments made were not material. The accounting for the tax effects of the Tax Act will be completed later in 2018.

The Tax Act also includes provisions to tax Global Intangible Low-Taxed Income (“GILTI”) of foreign subsidiaries in excess of a deemed return on their tangible assets. Due to the samecomplexities of the new provisions, we are continuing to evaluate how the provisions will be accounted for under U.S. GAAP. Pursuant to the Tax Act, corporations are allowed to make an accounting policy election of either (i) account for GILTI as a component of income tax expense in the period in 2016,which the corporation is subject to the rules (the “period cost method”), or (ii) account for GILTI in the corporation's measurement of deferred taxes (the “deferred method”). We have not currently elected a method and will do so after completing our analysis of the GILTI provisions of the Tax Act, depending on the analysis of our global income. Therefore, we have not recorded any potential deferred tax effects related to the GILTI in our financial statements and have no policy election regarding whether to record deferred taxes on GILTI or use the period cost method. We have, however, included an estimate of the current GILTI impact in our annual effective tax rate for 2018. We expect to complete the accounting during the measurement period.


Our effective tax rate during the three and six months ended June 30, 2018 differs from the statutory rate of 21%, primarily due to less favorable mix of foreign earnings taxed at varying rates and state income tax, offset by the benefits from restructuring charges and excess tax benefits related to share-based compensation resulting from adoptionbenefit of the accounting standard as described in Note 2 above.federal research and development credit.

As a result of recommendations by the Organisation for Economic Cooperation and Development, or OECD, on Base Erosion and Profit Shifting, or BEPS, certain countries in EMEA and APAC have either enacted new corporate tax legislation or are considering enacting such legislation in the near future. We expect the effect of these reform measures to potentially impact long-standing tax principles, particularly asin regards to transfer pricing. Consequently, we expect global tax authorities to increasingly challenge the Company’sour cost sharing and other intercompany arrangements, and the related sourcing of taxable profits in global jurisdictions. In 2016, the Company entered intoWe are continuing to hold discussions with the UK tax authorities and the Australian tax authorities regarding corporate tax reform legislation enacted by those countries.the UK.

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.

Operating Activities

Net cash provided by operations increaseddecreased during the six months ended June 30, 2017,2018, compared to the same period in 2016,2017. The decrease was primarily due to an increase inhigher cash collections from customers dueduring the first six months of 2017 related to higher invoicing activityservice renewals invoiced during the fourth quarter of 2016, partially offset byand an increase in cash paid during 2018 for income taxes, primarily due to the first

of eight annual transition tax payments related to the Tax Act. These decreases in cash flows were offset by a decline in cash paid for personnel-related expenses due to increased averagecosts, principally as a result of a reduction in headcount from workforce acquired from business combinations completed in the second half of 2016.and lower incentive compensation.

Investing Activities

Net cash provided by investing activities for the six months ended June 30, 2017 increased compared to net cash used in investing activities for the same period in 2016 primarily due to receipt of $75.0 million in proceeds from the Pulse Note and lower capital expenditures during the six months ended June 30, 2018, compared to the same period in 2017. The increase was primarily due to the liquidation of repatriated offshore investments to fund the accelerated share repurchase program discussed below.

Financing Activities

Net cash used in financing activities increased during the six months ended June 30, 2017,2018 compared to the same period in 2016, partially2017. The increase was primarily due to an increase in purchases and retirementhigher repurchases of our common stock, duringprimarily due to the six months ended June 30, 2017. During the six months ended June 30, 2016, we raised $494.0 million from our 2019 Notesaccelerated share repurchase program described further below, and 2024 Notes and repaid $300.0 millionincreases in payments of our 2016 Notes.cash dividends.

Capital Return

In 2014 and 2015,January 2018, 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$2.0 billion of our common stock, including $1.2 billion pursuant to an accelerated share repurchase program, and subsequent increases to the authorization totaling $1.8 billion, which we refer to as the 2018 Stock Repurchase Program. In February 2017, the Board authorized an additional $500.0 million increase to theThe 2018 Stock Repurchase Program replaces the previous authorization approved by the Board in 2014.

As part of the 2018 Stock Repurchase Program, during the quarter ended March 31, 2018, we entered into the ASR with two financial institutions to repurchase $750.0 million of our common stock. During the first quarter of 2018, we made an up-front payment of $750.0 million pursuant to the ASR and received and retired an initial 23.3 million shares of our common stock for a totalan aggregate price of $4.4 billion.$600.0 million, based on the market value of our common stock on the date of the transaction.

During the threethird quarter of 2018, the ASR was completed and six months ended June 30, 2017, we repurchased andreceived an additional 6.0 million shares from the financial institutions. These 6.0 million shares will be retired approximately 4.0 million and 8.5in the third quarter of 2018. The completion of the ASR resulted in a total settlement of 29.3 million shares of our common stock at a volume weighted average repurchase price, less an average priceagreed upon discount, of $30.59 and $29.25$25.62 per share, for an aggregate purchase price of $125.0 million and $250.0 million. share.

As of June 30, 2017,2018, there was $469.7 million$1.3 billion of authorized funds remaining under the 2018 Stock Repurchase Program.

In 2017, we intend to return approximately 50% of annual free cash flow to our stockholders, inclusive ofFuture share repurchases and dividends. Free cash flow is calculated as net cash provided by operating activities less capital expenditures.

Future stock repurchases under our stock repurchase programthe 2018 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 16, 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 June 30, 2017.Our 2018 Stock Repurchase Program may be discontinued at any time.

During the six months ended June 30, 2017,2018, we declared a quarterly cash dividend of $0.10$0.18 per share of common stock on January 26, 201730, 2018 and April 25, 2017,May 2, 2018, which was paid on March 22, 20172018 and June 22, 2017,2018, respectively, to stockholders of record on March 1, 20172018 and June 1, 2017, respectively,2018 in the aggregate amount of $75.8$124.9 million. Any future dividends, and the establishment of record and payment dates, are subject to approval by the Board or an authorized committee thereof. See Note 16,14, 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 June 30, 2017.2018.

Revolving Credit Facility

We have an unsecured revolving credit facility that will expire in 2019, which enables borrowings of up to $500.0 million, with the option, subject to the lenders' approval, to increase the amount of the credit facility by up to an additional $200.0 million. As of June 30, 2017,2018, we were in compliance with all covenants and there were no amounts outstanding under our unsecured revolving credit facility that will expire in 2019, which enables borrowings up to $500.0 million, with the option to increase the amount of the credit facility by up to an additional $200.0 million.facility.

Liquidity and Capital Resource Requirements

Liquidity and capital resources may be impacted by our operating activities as well as acquisitions, investments in strategic relationships, repurchases of additional shares of our common stock, and payment of cash dividends on our common stock. AsFollowing the enactment of June 30, 2017, 83%the Tax Act, we repatriated approximately $2.5 billion of our cash, cash equivalents and investment balances were heldinvestments balance from outside of the U.S., which may be subject as of June 30, 2018. We expect the new territorial tax system to U.S. taxes if repatriated.provide us lower cost access to nearly all of our global free cash flow on an ongoing basis. Free cash flow is calculated as net cash provided by operating activities less capital expenditures. We intend to use the repatriated cash to invest in the business, support value-enhancing merger and acquisitions, or M&A, and fund our return of capital to stockholders.

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, capital expenditures, commitments, and other liquidity requirements and anticipated growth for at least the next twelve months. However, our future liquidity and capital requirements may vary materially from those now planned depending on many factors, including, but not limited to, our growth rate, the timing and amount we spend to support development efforts, the expansion of sales and marketing activities, the introduction of new and enhanced products and services, the costs to acquire or invest in businesses and technologies, an increase in manufacturing or component costs, and the risks and uncertainties detailed in the “Risk Factors” section of Item 1A of Part II of this Report.

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, plans;
changes in customer mix, mix;
changes in the mix of products and services sold, sold;
changes in the mix of geographies in which our products and services are sold, sold;
changing market and economic conditions, conditions;
current and potential customer, partner and supplier consolidation and concentration, competition, concentration;
price and product competition;
long sales, qualification and implementation cycles, cycles;
unpredictable ordering patterns and reduced visibility into our customers’ spending plans and associated revenue;
how well we execute on our strategy and operating plans and the impact of changes in our business model that could result in significant restructuring charges;
our ability to achieve targeted cost reductions;
changes in tax laws or accounting rules, or interpretations thereof;
changes in the amount and frequency of share repurchases or dividends, dividends;
regional economic and political conditions,conditions; and
seasonality.

For example, we, and many companies in our industry, experience adverse seasonal fluctuations in customer spending, particularly in the first quarter. In addition, while we may have backlog orders for products that have not shipped, we believe that our backlog may not be a reliable indicator of future operating results for a number of reasons, including project delays, changes in project scope and the fact that our customers may cancel purchase orders or change delivery schedules without significant penalty. Furthermore, market trends, competitive pressures, commoditization of products, seasonal rebates and discounting, increased component or logistics costs, issues with product quality, regulatory impacts and other factors may result in reductions in revenue or pressure on gross margins 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,In the past, our operating results will behave been below our guidance, our long-term financial model or the expectations of securities analysts or investors, and this may happen in the future, in which case the price of our common stock may decline and has declined in the past. Such a decline could also occur, and has occurred in the past, even when we have met our publicly stated revenues and/or earnings guidance.


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

We expect our product and service gross margins to vary, both in the near-term and in the long-term, 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, some of which have occurred and may occur in the future, including customer, vertical, product and geographic mix shifts, an increase or decrease in our software sales or services we provide, increased price competition in one or more of the markets in which we compete, changes in the actions of our competitors or their pricing strategies, which may be difficult to predict and respond to, modifications to our pricing strategy in order to gain footprint in certain markets or with certain customers, currency fluctuations that impact our costs or the cost of our products and services to our customers, increases in material, labor, logistics, warranty costs, or inventory carrying costs, excess product component or obsolescence charges from our contract manufacturers, issues with manufacturing or component availability, quality or efficiencies, increased costs due to changes in component pricing or charges incurred due to inaccurately forecasting 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 2017, our margins decreased as compared to fiscal year 2016, primarily due to lower product net revenues and product mix, resulting from the year-over-year decline in routing revenues, our customers' architectural shifts, and higher costs of certain memory components. In fiscal year 2016, our margins decreased compared to fiscal year 2015, primarily due to elevated pricing pressure and product mix. In fiscal year 2015, our margins increased compared to fiscal year 2014, as a result of higher restructuring and other charges recorded in 2014 but not in 2015, in connection with the restructuring plan we initiated in the first quarter of 2014. 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 or any 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.

A limited number of our customers comprise a material portion of our revenues and any changes in the way they purchase products and services from us could affect our business. In addition, 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, across each customer vertical, depends on sales to a limited number of customers and distribution partners. Changes in the business requirements or focus, vendor selection, project prioritization, financial prospects, capital resources, and expenditures, or purchasing behavior (including product mix purchased or delays in deployment) 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, CenturyLink, Inc.'s acquisition of Level 3 Communications, Inc., Vodafone India’s proposed acquisition of Idea Cellular Ltd. and T-Mobile US, Inc.'s proposed acquisition of Sprint Corp.) and that consolidation trend has continued. Certain telecommunications companies have also moved towards vertical consolidation through acquisitions of media and content companies, such as Verizon’s acquisition of Yahoo and AT&T’s acquisition of Time Warner. 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 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 software and equipment they will use in those networks, such customers may greatly reduce or

suspend their spending on secure IP infrastructure. For example, in recent quarters, our switching and routing results were adversely affected by spending delays from our largest Cloud customers, who we believe are in the process of implementing a networking architectural shift. The duration of the delay is difficult to predict, in part because each Cloud customer will migrate their network architecture based on their own constraints. Such delays in purchases can make it more difficult to predict revenues from customers, can cause fluctuations in the level of spending by customers and, even where our products are ultimately selected, can have a material adverse effect on our business, financial condition, and results of operations.

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 salesrevenues 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 markets may adversely impact the ability of our customers to adequately fund their expected 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 and gross margins could cause significant variations in our operating results and operating margins from quarter to quarter. 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.

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, both in the near-term and in the long-term, 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, some of which have occurred and may occur in the future, including customer, product and geographic mix shifts, an increase or decrease in our software sales or services we provide, increased price competition in one or more of the markets in which we compete, changes in the actions of our competitors or their pricing strategies, which may be difficult to predict and respond to, 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, issues with manufacturing or component quality or efficiencies, increased costs due to changes in component pricing or charges incurred due to inaccurately forecasting 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 2016, our margins decreased compared to fiscal year 2015, primarily due to elevated pricing pressure and product mix. In fiscal year 2015, our margins increased compared to fiscal year 2014, as a result of higher restructuring and other 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 or any 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.

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 and business models in response to fluctuating market opportunities and conditions.

From time to time, we have increased investment in our business by, for example, increasing headcount, acquiring companies, 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. In addition, in February 2017 we initiated the 2017 Restructuring Plan to realign our workforce and increase operational efficiencies. This included workforce reductions and contract terminations. As we assessassessed the performance of our operating results against our long-term operating goals and evaluateevaluated potential opportunities for improvement, the 2017 Restructuring Plan could be subsequently amendedwas expanded and additional restructuring charges could be incurred.were incurred in the fourth quarter of 2017 to further align our workforce. 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 any changes in the way they purchase products and services from us could affect our business. In addition, 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 Telecom/Cable and Cloud verticals. Changes in the business requirements or focus, 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, Liberty Global's acquisition of Cable & Wireless Communications, Charter Communications, Inc.'s acquisition of Time Warner Cable, Inc., CenturyLink, Inc.'s proposed acquisition of Level 3 Communications, Inc., and Vodafone India’s proposed acquisition of Idea Cellular Ltd.) and that consolidation trend has continued. Certain telecommunications companies have also announced their intent towards vertical consolidation through acquisitions of media and content companies, such as Verizon’s acquisition of Yahoo and AT&T’s proposed acquisition of Time Warner. 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 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 hasrouting and switching markets have historically been dominated by Cisco, with competition coming from other companies such as Nokia Corporation (following its acquisition of Alcatel-Lucent), Arista, Brocade, HPE, 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 HPE.Fortinet. 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, HPE acquired Aruba Networks, Cisco acquired OpenDNS,Viptela, Symantec Corporation acquired Blue Coat Systems, and Dell acquired EMC, which further consolidated our market. 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 computercompute 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 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 certain software or subscriptions and professional, 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 dueDue to the cost, complexity and custom nature of configurations required by our customers; we generally build suchour network equipment 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 29%31%, 27%29%, and 26%27% of total revenue in fiscal year 2017, 2016, 2015, and 2014,2015, respectively. Sales of new or renewal professional services, 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 or those offered by our competitors, and reductions in our end-customers’ spending levels. We recognize professional services, support and maintenance revenue periodically over the term of the relevant service period.

The introduction of new software products and services is part of our intended strategy to expand our software business, and certain software revenues may be recognized periodically over the term of the relevant use period or subscription period. As a result, much of thecertain 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 such 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 ourcertain software products, 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 oursuch software or services revenue through additional software or services sales in any period, as revenue from new and renewalthose 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 technology roadmap 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, continuous pricing pressures and a constantly evolving industry. We cannot guarantee that we willmay not 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 wide area network, or WAN, infrastructures towards software-defined WAN, or SD-WAN, has been receiving considerable attention. In our view, it will take several years to see the full impact of SD-WAN, 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. In addition, if we invest time, energy and resources in developing products for a market that doesn't develop, it could likewise 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 tworecent years, we have announced a number of new products and enhancements to our hardware and software products across routing, switching and security. 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, our ability to support 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. 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 potentialpossibility that our strategy could erode our revenue and gross margins;

the impact on our financial results of longer periods of revenue recognition for certain types of software products
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

issues with third partythird-party technologies used with our disaggregated products may 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 foreign countries and is therefore subject to risks associated with doing business outside of the United States, including the possibility of import tariffs imposedor regional conflicts. For example, the United States and Chinese governments have each recently announced import tariffs, and the United States has announced additional proposed import tariffs, on certain products originating from the other country. These tariffs, depending upon their ultimate scope, duration and how they are implemented, could negatively impact our business by increasing our costs and by making our products less cost competitive. We may not be able to pass such increased costs on to our customers. In addition, increased costs of production or delays in production caused by any relocation of contract manufacturing facilities could impact the new administration.global competitiveness of our products. 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 for our products to our contract manufacturers and original design manufacturers, who order components and plan capacity based on these forecasts. If we overestimate our requirements, our original design or 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. In addition, some optical modules we use are experiencing faster product transitions than previous years, which increases the risk that we could have excess inventory of those modules. 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 products, 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.

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 risk environment means that individuals, companies, and organizations of all sizes, including Juniper, 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, in April 2016, we made additional changes to ScreenOS in response to our additional analysis as a part of an update of ScreenOS. 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, 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.

We are dependent on sole source and limited source suppliers, including for several key components, which makes us susceptible to shortages, quality issues 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 offor 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. For example, we are in the process of working through some industry-wide supply constraints related to power management components. In addition,
some optical transceivers and memory components used in our networking solutions might experience extended lead times and higher pricing, given the demand in the market. Any future spike in growth in our business, or more likelythe use of certain components we share in common with other companies, in IT spending andor 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. Wewe 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 and customer relationships could suffer until other sources can be developed. In addition, from time to time, wesuffer. We have experienced, and from time-to-time may experience, component shortages or quality issues that resulted, or could result, in delays of product shipments, revenue charges that impact our gross margins, and/or warranty or other claims. For example, in late 2016, we became aware of a defect in a clock-signal component from a third-party supplier that affected certain of our products and which resulted in remediation costs. As a result of this issue, we recorded a product cost of revenue charge that impacted our product gross margins for our fiscal year ended December 31, 2016 and three months ended March 31, 2017, and we may incur additionalclaims or costs. We also 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.China and Korea. 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. In addition, our suppliers may determine not to continue a business relationship with us for other reasons that may be beyond our control. 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 finished goods, the unavailability of raw materials, severe weather conditions, natural disasters, civil unrest, military conflicts, 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.

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 for our products to our contract manufacturers and original design manufacturers, who order components and plan capacity based on these forecasts. If we overestimate our requirements, our original design or 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. In addition, some optical modules we use are experiencing faster product transitions than our other products, which increases the risk that we could have excess inventory of those modules. Conversely, 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. Given that 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 products, our contract manufacturers may have inadequate time, materials, and/or components required to produce our products. This could increase costs or delay or interrupt manufacturing of our products, resulting in delays in shipments and deferral or loss of revenues and could negatively impact customer satisfaction.

System security risks, data protection breaches, and cyber-attacks could compromise our and our customers’ 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 that 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 risk environment means that individuals, companies, and organizations of all sizes, including Juniper, have been and 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 has experienced breaches and may be vulnerable in the future to breach or attacks by computer programmers, hackers or sophisticated nation-state and nation-state supported actors or breached due to employee error or wrongful conduct, malfeasance, or other disruptions. If any breach or attack compromises our networks, creates system disruptions or slowdowns or exploits security vulnerabilities of our products, the information stored on our networks or those of our customers 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, hardware, components and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including "bugs", vulnerabilities and other problems that could unexpectedly interfere with the operation of our networks or expose us or our products to cyber attacks. 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.

When vulnerabilities are discovered, we evaluate the risk, apply patches or take other remediation actions as required and notify customers and suppliers when appropriate. All of this requires significant time and attention from management and our employees.

As a result of any 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. As a large, well known provider of networking products, cyber attackers may specifically target our products or attempt to imitate us or our products in order to compromise a network. 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 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.

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, 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 2016, Nokia Corporation merged with Alcatel-Lucent, a competitor of ours, and in 2015 Cisco 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 byat the time we sell products to our distributors. If those distributors provide us withthese sales are made based on inaccurate or untimely information, the amount or timing of our revenues could be adversely impacted.

We are also vulnerable to third parties who illegally distribute or sell counterfeit, stolen or unfit versions of our products, which has happened in the past and could happen in the future. Such sales could have a negative impact on our reputation and business.

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.

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 withbetween the systems of third parties.two. For example, we are 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, cybersecurity attacks 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 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.



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 2017 we acquired Cyphort Inc. and in 2016, we acquired AppFormix Inc., Aurrion, Inc. and BTI Systems Inc. Acquisitions involve numerous risks, including, but not limited to, 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.

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 abilityimpact the amount of revenues to recognize revenues.be recognized.

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 deferimpact the amount of 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 15,13, 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, is conducting, and the U.S. Department of Justice, or the DOJ, arewas previously 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 conductingconducted a thorough internal 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 implementedmade improvements in its internal controls and continuescarried out a number of disciplinary actions. The Company is continuing to implement.fully cooperate with the SEC’s ongoing investigation, but believes an adverse outcome is reasonably possible and that it is likely

that the SEC will seek to bring an enforcement action against the Company. 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-consumingtime-consuming and expensive, as well as require a significant amount of resources to prosecute, defend, or make our products non-infringing.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. Third parties have asserted and may in the future assert claims or initiate litigation related to patent, copyright, trademark, and other intellectual property rights to technologies and related standards that are relevant to our products. The asserted claims and/or initiated litigation may include claims against us or our manufacturers, suppliers, partners, or customers, alleging that our products or services infringe proprietary rights. 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-

infringingnon-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 incorporate infringing technology in our products or if we license required proprietary rights at material expense, our business, financial condition, and results of operations could be materially and adversely affected.

Regulation of our 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. In addition, the European Union reached agreement in late 2016 on a EU-wide conflict minerals rule under which most EU importers of tin, tungsten, tantalum, gold and their ores will have to conduct due diligence to ensure the minerals do not originate from conflict zones and do not fund armed conflicts. Large manufacturers also will have to disclose how they plan to monitor their sources to comply with the rules. The regulation was adopted in 2017 with compliance required by 2021.

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 electricalelectronic equipment, including our products. Currently, our products comply with the EU RoHS requirements. However, certain exemptions are scheduled to lapse, or have lapsed, including an exemption for lead in network infrastructure equipment upon which we and our competitors had relied, which expired in July 2016.lapsed. The lapse of thisany 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.

In addition, as a contractor and subcontractor to U.S. government departments and agencies, we are subject to Federal regulations pertaining to our IT systems. For instance, as a subcontractor to the U.S. Department of Defense, or DOD, the Defense Federal Acquisition Regulation Supplement (DFARS) requiresrequired that our IT systems comply with the security and privacy controls described in National Institute of Standards and Technology Special Publication 800-171, or NIST SP 800-171. The DFARS requires DOD contractors and subcontractors to implement the NIST SP 800-171 controls no later than December 31, 2017. The DFARS also requires that we flow the security control requirement down to certain of our own subcontractors. Failure to comply with these requirements could result in a loss of Federal government business, subject us to claims or other remedies for non-compliance and negatively impact our business, financial condition, and results of operations.

The 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, in December 2017, the U.S. Federal Communications Commission has issuedrepealed its 2015 regulations governing aspects of fixed broadband networks and wireless networks. These regulations, which were challengedThis change in court, and which the new Federal Communications Commission leadership is considering removing or modifying,regulatory treatment of networks 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 regulationCertain governments also control importation and in-country use of encryption technology,items and technology. The scope, nature and severity of such as requiring certification, notifications, review of source code, limiting the encryption features or the escrowcontrols vary widely across different countries and governmental recovery of private encryption keys.may change frequently over time. For example, China has promulgated new cybersecurity regulations and published a new draft export law affecting networking products that may impair our ability to profitably market and sell our products in China. WeCertain countries’ encryption control regimes may significantly limit our ability to sell major lines of our products to both commercial customersin those countries.

Certain governments also impose special local content, certification, testing, source code review, escrow and directly and indirectly, to governments around the world.governmental recovery of private encryption keys, or feature requirements on network equipment for purposes of government procurements. Similar requirements may also be imposed in procurements by state owned entities (“SOE’s”). Our ability to sell into substantial government and SOE markets (whether or not the products we sell include encryption) is vulnerable to changes in applicable government procurement regulations, any associated local content requirements and changes in the government’s interpretation of such regulations. In addition, the U.S. government has broader sanctions and embargoes that generally forbid supply of most items to or involving certain countries, territories, governments, legal entities and individuals, including 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.


In addition, governments sometimes impose additional taxes on certain imported products. For example, the United States and Chinese governments have each recently announced import tariffs on certain products originating from the other country. These tariffs, depending upon their ultimate scope, duration and how they are implemented, could negatively impact our business by increasing our costs and by making our products less cost competitive.

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 previously 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, which we refer to as the Safe Harbor, agreed to by the U.S. Department of Commerce and the EU. The Safe Harbor, 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., was invalidated in 2015 by a decision of the European Court of Justice, or the ECJ. Now that the EU and U.S. have implemented a successor privacy framework called the Privacy Shield, we are reviewing and documenting our practices required to obtain certification under the Privacy Shield, in addition to entering into EU Model Contracts with our vendors where appropriate and feasible in anticipation of the possibility that either the Privacy Shield or EU Model Contracts may be legally challenged or voided like Safe Harbor in an uncertain political environment. In addition, the EU General Data Protection Regulation, which will be effectivewent into full effect in May 2018, is expected to resulthas resulted in substantial changes to our compliance obligations, including contractual requirements for data transfers outside the EEA, and a significant increase in potential administrative fines for non-compliance. Similarly, the June 2016 approval by voters in the United Kingdom,

or U.K., of a referendum to leave the EU could require us to make additional changes to the way we conduct our business and transmit data between the U.S., U.K., EU and the rest of the world.

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 with specialized industry expertise, 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.

A number of our team members are foreign nationals who rely on visas and entry permits in order to legally work in the United States and other countries. In recent years, the United States has increased the level of scrutiny in granting H-1(B), L-1 and other business visas. In addition, the current U.S. administration has indicated that immigration reform is a priority. Compliance with United States immigration and labor laws could require us to incur additional unexpected labor costs and expenses or could restrain our ability to retain skilled professionals. Any of these restrictions could have a material adverse effect on our business, results of operations and financial conditions.

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 June 30, 2017,2018, our goodwill was $3,079.4$3,096.1 million and intangible assets with indefinite lives was $49.0 million. When the carrying value of a reporting unit’s goodwill exceeds its implied fair value of goodwill, or 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.

From time to time, 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, or sustained declines in our stock price, increase the risk that goodwill and intangible assets with indefinite lives may become impaired in future periods.

During the three months ended June 30, 2017, we concluded that there were sufficient indicators to require us to perform an interim goodwill impairment analysis on our Security reporting unit. Based on our analysis, we determined that our Security reporting unit’s goodwill iswas not impaired. However, 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; limitations on the deductibility of net interest expense; or changes in tax laws, regulations, accounting principles, or interpretations thereof. For example, on July 24, 2018, the Ninth Circuit Court of Appeals, or the Court, issued an opinion in Altera Corp. v. Commissioner requiring related parties in an intercompany cost-sharing arrangement to share expenses related to share-based compensation. On August 7, 2018, the Court withdrew its opinion to allow time for a reconstituted panel to confer. We are monitoring this case and any impact the final opinion could have on our financial statements. In addition, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), which was signed into law on December 22, 2017, makes significant changes to the taxation of U.S. business entities that will have a meaningful impact to our provision for income taxes. These changes include a reduction to the federal corporate income tax rate, the current taxation of certain foreign earnings, the imposition of base-erosion prevention measures which may limit the deduction of certain transfer pricing payments, and possible limitations on the deductibility of net interest expense or corporate debt obligations. Accounting for the income tax effects of the Tax Act requires significant judgments and estimates that are based on current interpretations of the Tax Act and could be affected by changing interpretations of the Act, as well as additional legislation and guidance around the Act. Any refinements to these provisional estimates are difficult to predict and could impact our results.

Furthermore, on October 5, 2015, the Organisation for Economic Co-operation and Development, or OECD, an international association of 35 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, as adopted by countries, may increase tax uncertainty and adversely affect our provision for income taxes. Furthermore, the current U.S. administration and key members of Congress have made public statements indicating that tax reform is a priority. Certain changes to U.S. tax laws, including limitations on the ability to defer U.S. taxation on earnings outside of the United States until those earnings are repatriated to the United States, could affect the tax treatment of our foreign earnings. 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. 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;

laws that restrict sales of products developed or manufactured outside of the country;

varying and potentially conflicting laws and regulations;

fluctuations in local economies;

wage inflation or a tightening of the labor market;


tax policies that could have a business impact;

potential import tariffs imposed by the United States and the possibility of reciprocal tariffs by foreign countries;

data privacy rules and other regulations that affect cross border data flow; and

the impact of the following on customer 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.

In addition, the June 2016 approval by voters inU.K.’s exit from the U.K. of a referendum to leave the EU, and the U.K.’s formal initiation of the exit process in March 2017, commonly referred to as Brexit, has caused, and may continue to cause, uncertainty in the global markets. The U.K.’s exit from the EU,Brexit, if implemented, will take some period of time to complete and could result in regulatory changes that impact our business. For example, changes to the way service providers conduct business and transmit data between the U.K. and the EU could require us to make changes to the way we handle customer data. We will also review the impact of any resulting changes to EU or U.K. law that could affect our operations, such as labor policies, financial planning, product manufacturing, and product distribution. Political and regulatory responses to the vote are still developing and we are in the process of assessing the impact the vote may have on our business as more information becomes available. Nevertheless, because we conduct business in the EU, including the U.K., any of the effects of Brexit, including those we cannot anticipate, could have a material adverse effect on our business, operating results, financial condition and cash flows.

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, 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.

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. These errors may arise from hardware or software we produce or procure from third parties. 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, negative publicity, 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.

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, Chinese Yuan, Euro, and Indian Rupee 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 currency exposures associated with certain assets and liabilities denominated in nonfunctional currencies and periodically hedge anticipated foreign currency cash flows, with the aim of offsetting the impact of currency fluctuations on these exposures. However, hedge activities can be costly, and hedging cannot fully offset all risks, including long-term declines or appreciation in the value of the U.S. Dollar. If our attempts to hedge against these risks are not successful, or if long-term declines or appreciation in the value of the U.S. Dollar persist, our financial condition and results of operations could be adversely impacted.

A portion 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 $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, we and the issuer of the promissory note agreed to modify the original terms of the note to extend the maturity date from April 1, 2016 to December 31, 2018. On May 1, 2017, we received a principal payment in the amount of $75.0 million and outstanding interest on the note and we and the issuer agreed to further amend the terms of the note with respect to the remaining approximately $58.0 million to, among other things, extend the maturity date from December 31, 2018 to September 30, 2022, provide that interest due can be paid in kind by increasing the outstanding principal amount of the note and subordinate the note to other debt issued by senior lenders. Since a portion of the transaction consideration is in the form of a non-contingent seller promissory note and the note is subordinated to debt issued by senior lenders, there is the risk that we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, 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 and there is no guarantee that we will be able to recover the amounts owed to us in full.

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 improve our systems and processes or we fail to monitor and ensure that these systems and processes are being used correctly, our ability to manage our business, financial condition, and results of operations may be negatively 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 renegotiate our current third party licenses or license additional technology from third-parties to develop new products or product enhancements or to facilitate new business models. 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. Third party technology we incorporate into our products that is deemed to infringe on the intellectual property of others may result, and in some cases has resulted, in limitations toon our ability to source technology from those third parties, restrictions on our ability to sell products that incorporate the infringing technology, increased exposure to liability that we will be held responsible for incorporating the infringing technology in our products and increased costs involved in removing that technology from our products

or developing substitute technology. 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 software and 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, and our stock price.

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 or detected in a timely manner. We have an ongoing program to review the design of our internal controls framework in keeping with changes in business needs, implement necessary changes to our controls design and test the system and process controls necessary to comply with these requirements. If in the future, our internal controls over financial reporting are determined

to be not effective resulting in a material weakness or significant deficiency, 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 Notes and the Revolving Credit Facility.

As of June 30, 2017,2018, we have issued $2,150.0$2,150 million in aggregate principal amount of senior notes, which we refer to collectively as the Notes, and had $2,135.0$2,137.7 million in outstanding short-term and long-term debt (see discussion in Note 9, Debt and Financing, in the Notes to Consolidated Financial Statements of this Report).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 by up to an additional $200.0 million. The Credit Agreement will terminate in June 2019, at which point all amounts borrowed must be repaid. As of June 30, 2017,2018, 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, and the Revolving Credit Facility (if drawn upon).

In addition, certain changes under the Tax Act may result in limitations on the deductibility of our net business interest expenses. Beginning in 2018, the Tax Act generally limits the annual deduction for net business interest expense to an amount equal to 30% of adjusted taxable income. As a result, if our taxable income were to decline, we may not be able to fully deduct our net interest expense. These changes, among others under the Tax Act, could result in increases to our future U.S. tax expenses, which could have a material impact on our business.

A portion 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 $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, we and the issuer of the promissory note agreed to modify the original terms of the note to extend the maturity date from April 1, 2016 to December 31, 2018. On May 1, 2017, we received a principal payment in the amount of $75.0 million and outstanding interest on the note and we and the issuer agreed to further amend the terms of the note with respect to the remaining approximately $58.0 million to, among other things, extend the maturity date from December 31, 2018 to September 30, 2022, provide that interest due can be paid in kind by increasing the outstanding principal amount of the note and subordinate the note to other debt issued by senior lenders. Since a portion of the transaction consideration is in the form of a non-contingent seller promissory note and the note is subordinated to debt issued by senior lenders, there is the risk that we may not receive the amount owed to us (including accrued interest), including in the time frame contemplated, 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 and there is no guarantee that we will be able to recover the amounts owed to us in full.

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.

Our ability to pay quarterly dividends or achieve our intended capital return policy will be subject to, among other things, our financial position and results of operations, available cash and cash flow, capital and debt service requirements, use of cash for acquisitions and other factors. Any failure to pay or increase future dividends as announced, or a reduction or discontinuation of quarterly dividends could have a material adverse effect on our stock price.

We have announced that, beginning in 2017, we intend to target a capital return policy, inclusive of share repurchases and dividends, of approximately 50% of annual free cash flow. Free cash flow is calculated as net cash provided by operating activities less capital expenditures. In January 2018, we announced that our Board of Directors approved a new $2 billion buyback authorization, which replaced our prior authorization. In February 2018, as a part of our new buyback authorization, we entered into a $750 million accelerated share repurchase program, and our Board of Directors declared an increase to our quarterly cash dividend to $0.18 per share, which reflects an increase of 80% compared to previous quarterly dividends. Any failure to meet our commitments to return capital to our shareholdersstockholders 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 and equity securities are subject to risks, which may cause losses and affect the liquidity of these investments.

At June 30, 2017,2018, we had $2,392.5$2,690.4 million in cash and cash equivalents and $1,822.1$840.1 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, money market funds, mutual funds, publicly-traded equity securities, time deposits, U.S. government agency securities, and U.S. government securities. We also have $88.6 million in other long-term assets for our investments in privately-held companies. Certain of theseour 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. In addition, our insurance coverage may not be adequate to compensate us for all losses or failures that may occur. Losses not covered by insurance could be substantial and unpredictable and could adversely affect our financial condition and results of operations.

Our stock price may be volatile.

Historically, our common stock has experienced substantial price volatility, particularly as a result of variations between our actual financial results and the published expectations of analysts and as a result of announcements by our competitors and us. Furthermore, speculation in the press or investment community about our strategic position, financial condition, results of operations, business, security of our products, or significant transactions can cause changes in our stock price. In addition, the stock market has experienced extreme price and volume fluctuations that have affected the market price of many technology companies in particular and that have often been unrelated to the operating performance of these companies. These factors, as well as general economic and political conditions and the announcement of proposed and completed acquisitions or other significant transactions, or any difficulties associated with such transactions, by us or our current or potential competitors, may materially adversely affect the market price of our common stock in the future.



Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

The following table provides a summary of stockThere were no repurchases during the three months endedJune 30, 20172018. As of June 30, 2018, there were $1.4 billion of authorized funds remaining under the 2018 Stock Repurchase Program.

As part of the 2018 Stock Repurchase Program, we entered into the ASR in February 2018 with two financial institutions to repurchase $750.0 million of our common stock. During the three months ended March 31, 2018, we made an up-front payment of $750.0 million pursuant to the ASR and received and retired an initial 23.3 million shares of our common stock for an aggregate price of $600.0 million based on the market value of our common stock on the date of the transaction. The remaining $150.0 million was recorded as a forward contract indexed to the price of our common stock. During the third quarter of 2018, the ASR was completed and we received an additional 6.0 million shares from the financial institutions. These 6.0 million shares will be retired in the third quarter of 2018. The completion of the ASR resulted in a total settlement of 29.3 million shares of our common stock at a volume weighted average repurchase price, less an agreed upon discount, of $25.62 per share.

(1), in Notes to Condensed Consolidated Financial Statements in Item 1 of Part I of this Report.
Shares were repurchased under our Board approved Stock Repurchase Program, which authorized us to purchase an aggregate of up to $4.4 billion of our common stock. Future share repurchases will be subject to a review of the circumstances in place at that time and will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. This program may be discontinued at any time.
