Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1. Organization and Basis of Presentation ARRIS International plc (together with its consolidated subsidiaries and consolidated venture, except as the context otherwise indicates, “ARRIS” or the “Company”) is a global entertainment, communications, and networking technology and solutions provider, headquartered in Suwanee, Georgia. The Company operates in three business segments, Customer Premises Equipment (“CPE”), Network & Cloud (“N&C”) and Enterprise Networks (“Enterprise”) (See Note 15 Segment Information The consolidated financial statements include the accounts of the Company and its wholly owned foreign and domestic subsidiaries and consolidated venture in which the Company owns more than 50% of the outstanding voting shares of the entity. All intercompany accounts and transactions have been eliminated. The accompanying financial data as of September 30, 2018 and for the three and nine months ended September 30, 2018 and September 30, 2017 has been prepared by the Company, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been condensed or omitted pursuant to such rules and regulations. The December 31, 2017 Consolidated Balance Sheet was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017. In the opinion of management, all normal recurring adjustments necessary to present fairly the consolidated balance sheet as of September 30, 2018, the consolidated statements of operations, the statements of comprehensive income (loss), and the statements of cash flows for the three and nine months ended September 30, 2018 and September 30, 2017 as applicable, have been made. Certain prior year amounts in the financial statements and notes have been reclassified to conform to the fiscal year 2018 presentation. The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Accounting Changes and Error Corrections [Abstract]
Impact of Recently Adopted Accounting Standards	Note 2. Impact of Recently Adopted Accounting Standards Adoption of new accounting standards There are two permitted transition methods under the new standard, the full retrospective method or the modified retrospective method. Under the full retrospective method, the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown on the face of the financial statements being presented. Under the modified retrospective method, the cumulative effect of applying the standard would be recognized at the date of the initial application of the standard and the effect of the prior periods would be calculated and shown through a cumulative effect change in retained earnings. ARRIS adopted the standard using the modified retrospective method on January 1, 2018. (See Note 3 Revenue from Contracts with Customers In January 2016, the FASB issued an update to amend certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Under this standard, certain equity investments are measured at fair value with changes recognized in current period earnings as opposed to other comprehensive income (loss). This guidance is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. In August 2016, the FASB issued amended guidance on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of the amended guidance is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic. The amended guidance adds or clarifies guidance on eight cash flow issues, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or certain other debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions and separately identifiable cash flows and application of the predominance principle. The guidance is effective for the Company beginning January 1, 2018 for both interim and annual reporting periods, with early adoption permitted. Entities must apply the guidance retrospectively to all periods presented but may apply it prospectively from the earliest date practicable if retrospective application would be impracticable. ARRIS adopted this update as of January 1, 2018. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position and results of operations. In November 2016, the FASB issued new guidance that requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new guidance is effective for interim and annual periods beginning after December 15, 2017. ARRIS adopted this update retrospectively as of January 1, 2018. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position and results of operations. In March 2017, the FASB issued an accounting standard update that requires entities to disaggregate the service cost component from the other components of net periodic benefit costs and present it with other current compensation costs for related employees in the income statement and present the other components elsewhere in the income statement and outside of income from operations if that subtotal is presented. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable. The accounting standard update is effective for the Company in the first quarter of fiscal 2018. ARRIS adopted this update as of January 1, 2018. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position and results of operations. In May 2017, the FASB issued an accounting standard which amends the scope of modification accounting for share-based payment arrangements. The standard provides guidance on 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. The accounting standard will be applied prospectively to awards modified on or after the effective date. It is effective for interim and annual periods beginning after December 15, 2017 (January 1, 2018 for the Company). ARRIS adopted this update as of January 1, 2018. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position and results of operations. In August 2018, the FASB issued an accounting standard update related to customer's accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. The standards update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The capitalized implementation costs of a hosting arrangement that is a service contract will be expensed over the term of the hosting arrangement. The accounting standard is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period. The amendments can be applied either retrospectively or prospectively to all implementation costs incurred after the adoption date. The Company early adopted this standard in the third quarter of 2018 using the prospective method. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position and results of operations. Accounting standards issued but not yet effective The new standard requires a modified retrospective transition through a cumulative-effect adjustment as of the beginning of the earliest period presented in the financial statements, although the FASB recently approved an option for transition relief to not restate or make required disclosures under the new standard in comparative periods in the period of adoption. Along with that transition relief, the FASB also recently approved a practical expedient for lessors to allow for the combined presentation of lease and non-lease revenues when certain conditions are met. Many factors will impact the ultimate measurement of the lease liability and corresponding right of use asset to be recognized upon adoption. The Company continues to evaluate the impact this guidance will have on its consolidated financial statements. The Company expects to take advantage of the transition relief provided by the amendment to the new guidance which allows us to elect not to restate 2017 and 2018 comparative periods upon adoption and continue to apply existing guidance to such periods. With respect to the other practical expedients, the Company expects to elect the package of three expedients, which allows us not to reassess the existence, the classification or the amount and treatment of initial direct costs for existing leases. The Company does not expect to apply hindsight for the evaluation of lease options (e.g., renewal). The Company expects to elect not to record on the balance sheet a lease with a term (including reasonably certain renewal or purchase options, or reasonably certain not to terminate) of less than 12 months. Finally, the Company expects to elect the practical expedient which allows us not to separate lease and non-lease components. This guidance becomes effective January 1, 2019 with early adoption permitted. The Company has established a project management team to analyze the impact of this standard, including its current accounting policies and practices to identify potential impacts that would result from the application of this standard. The Company’s adoption process of the new standard is ongoing, including evaluating and quantifying the impact on its consolidated financial statements, identifying the population of leases (and embedded leases), implementing a selected technology solution and collecting and validating lease data. The Company expects its lease obligations designated as operating leases (as disclosed in Note 23 to the audited consolidated financial statements in its most recent Annual Report on Form 10-K) will be reported on the consolidated balance sheets upon adoption. In January 2017, the FASB issued an accounting standard update that clarifies the definition of a business to help companies evaluate whether acquisition or disposal transactions should be accounted for as asset groups or as businesses. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a prospective basis. The impact of this accounting standard update will be facts and circumstances dependent, but the Company expects, that in some situations, transactions that were previously accounted for as business combinations or disposal transactions will be accounted for as asset purchases or asset sales under the accounting standard update. In August 2017, the FASB issued an accounting standard which eliminates the requirement to separately measure and report hedge ineffectiveness and requires companies to recognize all elements of hedge accounting that impact earnings in the same income statement line item where the hedged item resides. The standard includes new alternatives for measuring the hedged item for fair value hedges of interest rate risk and eases the requirements for effectiveness testing, hedge documentation and applying the critical terms match method. Finally, the standard introduces new alternatives that permit companies to reduce the risk of material error if the shortcut method is misapplied. The accounting standard is effective beginning January 1, 2019 and is required to be applied prospectively. The Company is currently assessing the potential impact of the adoption of this standard on its Consolidated Financial Statements. In February 2018, the FASB issued an accounting standard which allows companies to reclassify stranded tax effects resulting from the U.S. 2017 Tax Cuts and Jobs Act, from accumulated other comprehensive income to retained earnings. The guidance also requires certain new disclosures regardless of the election. The accounting standard is effective in the first quarter of fiscal 2020, and earlier adoption is permitted. In August 2018, the FASB issued an accounting standard update which amends fair value measurement disclosure requirements aiming to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures. This guidance will be effective for interim and annual periods beginning after December 15, 2019 and early adoption is permitted. Adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued an accounting standard update that eliminated certain disclosures about defined benefit plans, added new disclosures, and clarified other requirements. This guidance will be effective for interim and annual periods beginning after December 15, 2020 and early adoption is permitted. There were no changes to interim disclosure requirements. Adoption of this guidance is not expected to have a material effect on the Company’s annual financial statement statements.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Note 3. Revenue from Contracts with Customers On January 1, 2018, the Company adopted the new accounting standard Revenue from Contracts with Customers $2.7 million increase in shareholder’s equity attributable to noncontrolling interest. Revenue Recognition ARRIS generates revenue from varying activities, including the delivery of stand-alone equipment, custom design and installation services, and bundled sales arrangements inclusive of equipment, software and services. Revenue is recognized when performance obligations in a contract are satisfied through the transfer of control of the good or service at an amount of consideration expected to receive. The following are required before revenue is recognized: · Identify the contract with the customer. A variety of arrangements are considered contracts; however, these are usually the Master Purchase Agreement and amendments or customer purchase orders. · Identify the performance obligations in the contract. Performance obligations are identified as promised goods or services in an arrangement that are distinct. · Determine the transaction price. Transaction price is the amount of consideration the Company expects in exchange for transferring the promised goods or services. The consideration may include fixed or variable amounts or both. · Allocate the transaction price to the performance obligations. The transaction price is allocated to the performance obligations on a relative standalone selling price basis. · Recognize revenue as the performance obligations are satisfied. Revenue is recognized when transfer of control of the promised goods or services has occurred. This is either at a point in time or over time. Revenue is deferred for any performance obligations in which payment is received or due prior to the transfer of control of the good or service. Equipment The Company’s equipment deliverables typically include proprietary operating system software, which isn’t considered separately identifiable. Therefore, ARRIS’s equipment deliverables are considered one distinct performance obligation. Multiple Performance Obligation Arrangements To determine the standalone selling price (“SSP”), the Company first looks to establish SSP through an observable price when the good or service is sold separately in similar circumstances. If SSP cannot be established through an observable price, the Company will estimate the SSP considering market conditions, customer specific factors, and customer class. The Company typically uses a combination of approaches to estimate SSP. Software Sold Without Tangible Equipment Standalone Services · Maintenance and support services, provided under annual service-level agreements with the Company’s customers. These services represent stand-ready obligations that are recognized over time (on a straight-line basis over the contract period) because the customer simultaneously receives and consumes the benefits of the services as the services are performed. · Professional services and other similar services consist primarily of “Day 2” services to help customers maximize their utilization of deployed ARRIS systems. The services · Installation services relate to the routine installation of equipment ordered by the customer at the customer’s site and are distinct performance obligations from delivery of the related hardware. The associated revenues are recognized over time as the services are provided, which is generally a very short period (less than a couple of days). Incentives – Value Added Resellers (VAR), Distribution Channels and Retail Sales through retail and distribution channels are made primarily under agreements or commitments allowing for limited rights of return, primarily for stock rotation purposes, and include various sales incentive programs, such as back-end rebates, discounts, marketing development funds, price protection, and incentives. Enterprise sales distributors are granted rights of stock rotation that are limited to contractually specified percentage of the distributors aggregate purchase volume. These stock rotation rights are subject to expiration 180 days from the time of product shipment by us to the distributor. Upon shipment of the product, ARRIS reduces revenue for an estimate of potential future stock rotation returns related to the current period product revenue. ARRIS analyzes historical returns, channel inventory levels, current economic trends and changes in customer demand for our products when evaluating the adequacy of the allowance for sales returns, namely stock rotation returns. Regarding the various incentive programs, the Company can reasonably estimate its backend rebates, discounts and similar incentives due to an established sales history with its customers and records the estimated reserves and allowances at the time the related revenue is recognized. The Company recognizes marketing development funds at the later of when the related revenue is recognized, or the program is offered to the channel partner. ARRIS’s sales incentives to its channel partners are recorded as a reduction to revenue. ARRIS’s estimated allowances for returns due to stock rotation and various sales incentive programs can vary from actual results that could materially impact our financial position and results of operations. Based on the relevant facts and circumstances, the Company believes the methodologies applied to calculate these reserves fairly represents our expected results at the point in time in which they are made.

Other Contract Assets and Liabilities When payments from customers are received in advance of performance, the Company records a contract liability (deferred revenue). When the Company fulfills performance obligations prior to being able to invoice the customer, a contract asset (unbilled receivables) is recorded. Additionally, the balances for these are calculated at the contract level on a net basis. The unbilled receivables are included in Accounts Receivable on the unaudited Consolidated Balance Sheets. As of September 30, 2018, the Company has unbilled receivables of $45.0 million. The changes in the contract asset account relate to license revenue is now being recognized upon delivery instead of being recognized ratably over the license term. The following table summarizes the changes in deferred revenue for the nine months ended of September 30, 2018 (in thousands) Opening balance at January 1, 2018 $ 168,757 Deferral of revenue 127,467 Recognition of unearned revenue (120,712 ) Other (970 ) Balance at September 30, 2018 $ 174,542 As of the end of the current reporting period, the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied that have a duration of one year or more was $66.4 million. The majority of ARRIS’s contracts that have performance obligations that are unsatisfied are part of contracts have a duration of one year or less. Practical Expedients Sales commissions are incremental contract acquisition costs which are expected to be recovered. The Company has elected to recognize these expenses as incurred due to the amortization period of these costs being one year or less. Costs to obtain or fulfill a contract are incremental costs that are expected to be recovered. The Company has elected to recognize these expenses as incurred due to the amortization period of these costs being one year or less. Costs to obtain a contract that would have been incurred regardless of whether the contract was obtained are recognized in expense when incurred. The Company has elected not to adjust the promised amount of consideration for the effects of a significant financing component when it expects, at contract inception, that the period between when ARRIS transfers a promised good or service to a customer, and when the customer pays will be one year or less. The Company has elected the expedient that states an entity does not need to evaluate whether shipping and handling activities are promised services to its customers. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities are accrued. The Company has also elected to exclude from the transaction price certain types of taxes collected from a customer and remitted to a third-party (e.g., governmental agency), including sales, use and value-added taxes. As a result, revenue is presented net of these taxes. Additionally, the Company has elected for contracts that were modified before the beginning of the earliest reporting period to reflect the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price, and allocating the transaction price.

Business Combinations [Abstract]
Business Acquisition	Note 4. Business Acquisition Acquisition of Ruckus Wireless and ICX Switch business On December 1, 2017, ARRIS completed the acquisition of Ruckus Wireless and ICX Switch business (“Ruckus Networks”). The total cash paid was approximately $761.0 million (net of estimated adjustments for working capital and noncash settlement of pre-existing payables and receivables) The purchase agreement provides for customary final adjustments and potential cash payments or receipts that are expected to occur in 2018. With this acquisition, ARRIS expands its leadership in converged wired and wireless networking technologies beyond the home into the education, public venue, enterprise, hospitality, and multi-dwelling unit markets. The preliminary estimated goodwill of $310.8 million arising from the acquisition is attributable to the strategic opportunities and synergies that are expected to arise from the acquisition of Ruckus Networks and the workforce of the acquired business. Goodwill has been preliminarily assigned to our new Enterprise reporting unit as of September 30, 2018. The Company will finalize the assignment during the measurement period. A portion of the goodwill is expected to be deductible for income tax purposes. The following table summarizes the fair value of consideration transferred for Ruckus Networks (in thousands): Cash consideration $ 779,743 Estimated working capital adjustments (16,371 ) Non-cash consideration (1) (2,359 ) Total consideration transferred $ 761,013 (1) Non-cash consideration represents a $2.4 million settlement of preexisting payables and receivables between Ruckus Networks and ARRIS. The following is a summary of the estimated fair values of the net assets acquired (in thousands): Amounts Recognized as Adjustments Amounts Recognized Total estimated consideration transferred $ 761,013 $ — $ 761,013 Cash and cash equivalents 18,958 — 18,958 Accounts receivable, net 32,940 (5,999 ) 26,941 Inventories 48,897 (461 ) 48,436 Prepaids & other 4,836 (1,006 ) 3,830 Property, plant & equipment 33,500 (1,637 ) 31,863 Intangible assets 472,500 22,200 494,700 Other assets 39,528 (37,897 ) 1,631 Accounts payable and accrued liabilities (17,216 ) 1,523 (15,693 ) Other current liabilities (9,666 ) (1,988 ) (11,654 ) Deferred revenue (47,718 ) 970 (46,748 ) Noncurrent deferred income tax liabilities (92,233 ) (7,643 ) (99,876 ) Other noncurrent liabilities (41,347 ) 39,160 (2,187 ) Net assets acquired 442,979 7,222 450,201 Goodwill $ 318,034 (7,222 ) $ 310,812 (a) As previously reported as of December 31, 2017 As a result of measurement period changes for intangible assets, the Company recorded a decrease to previously recorded amortization for quarters ended December 31, 2017 and March 31, 2018 of $1.8 million and $1.0 million, respectively. These adjustments have been recorded prospectively in the first nine months of 2018. The acquisition was accounted for using the acquisition method of accounting, which requires, among other things, that the assets acquired, and liabilities assumed be recognized at their acquisition date fair values, with any excess of the consideration transferred over the estimated fair values of the identifiable net assets acquired recorded as goodwill. The accounting for the business combination is based on currently available information and is considered preliminary. The Company has not received a final valuation report from the independent valuation expert for acquired property, plant and equipment and intangible assets. In addition, the Company is still gathering information about income taxes and deferred income tax assets and liabilities, accounts receivables, warranty obligations, other assets and accrued liabilities based on facts that existed as of the date of the acquisition. The final accounting for the business combination may differ materially from that presented in these unaudited consolidated financial statements. The $494.7 million of acquired intangible assets are comprised of the following (in thousands): Preliminary Estimated Weighted Technology and patents $ 217,900 5.4 Customer contracts and relationships 195,400 10.0 Tradenames 55,400 indefinite Trademarks and tradenames 10,700 10.0 Backlog 15,300 0.3 Total estimated fair value of intangible assets $ 494,700 The fair value of trade accounts receivable is $26.9 million with the gross contractual amount being $28.1 million. The Company expects $1.2 million to be uncollectible. The Company incurred acquisition related costs of $0.1 million and $0.7 million during the three and nine months ended September 30, 2018, respectively. This amount was expensed by the Company as incurred and is included in the Consolidated Statement of Operations in the line item titled “Integration, acquisition, restructuring and other costs”. The Ruckus Networks business contributed revenues of approximately $522.3 million to the Company’s consolidated results for the nine months ended September 30, 2018.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	Note 7. Fair Value Measurement Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S GAAP establishes a fair value hierarchy that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities. To increase consistency and comparability in fair value measurements, the FASB has established a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels. An asset or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the measurement of its fair value. The three levels of input defined by U.S GAAP are as follows: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.

The following table presents the Company’s investment assets (excluding equity and cost method investments) and derivatives measured at fair value on a recurring basis as of September 30, 2018 and December 31, 2017 (in thousands): September 30, 2018 Level 1 Level 2 Level 3 Total Certificates of deposit (non-U.S.) $ — $ 39,640 $ — $ 39,640 Corporate obligations — 14 — 14 Money markets 37 — — 37 Mutual funds 86 — — 86 Other investments — 5,859 — 5,859 Interest rate derivatives — asset derivatives — 24,480 — 24,480 Interest rate derivatives — liability derivatives — — — — Foreign currency contracts — asset position — 3,806 — 3,806 Foreign currency contracts — liability position — (605 ) — (605 ) December 31, 2017 Level 1 Level 2 Level 3 Total Certificates of deposit (non-U.S.) $ — $ 12,809 $ — $ 12,809 Corporate bonds — 11,065 — 11,065 Corporate obligations — 13 — 13 Money markets 38 — — 38 Mutual funds 79 — — 79 Other investments — 5,588 — 5,588 Interest rate derivatives — asset derivatives — 10,156 — 10,156 Interest rate derivatives — liability derivatives — (4,024 ) — (4,024 ) Foreign currency contracts — asset position — 405 — 405 Foreign currency contracts — liability position — (8,802 ) — (8,802 ) In addition to the financial instruments included in the above table, certain nonfinancial assets and liabilities are measured at fair value on a nonrecurring basis in accordance with applicable authoritative guidance. This includes items such as nonfinancial assets and liabilities initially measured at fair value in a business combination (but not measured at fair value in subsequent periods) and nonfinancial long-lived asset groups measured at fair value for an impairment assessment. In general, nonfinancial assets including goodwill, other intangible assets and property and equipment are measured at fair value when there is an indication of impairment and are recorded at fair value only when any impairment is recognized. During the nine months ended September 30, 2018, the Company recorded partial impairment of goodwill of $3.4 million related to our Cloud TV reporting unit, of which $1.2 million is attributable to the noncontrolling interest, respectively. During the fourth quarter of 2017, the Company recorded partial impairments of goodwill and indefinite-lived tradenames of $51.2 million and $3.8 million, respectively, acquired in the ActiveVideo acquisition and included as part of the Cloud TV reporting unit, of which $19.3 million is attributable to the noncontrolling interest. See Note 5 Goodwill and Intangible Assets The Company believes the principal amount of debt as of September 30, 2018 approximated fair value because of interest-bearing rates that are adjusted periodically, analysis of recent market conditions, prevailing interest rates, and other Company specific factors. The Company has classified the debt as a Level 2 item within the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Note 8. Derivative Instruments and Hedging Activities Overview ARRIS is exposed to financial market risk, primarily related to foreign currency and interest rates. These exposures are actively monitored by management. To manage the volatility related to certain of these exposures, the Company enters a variety of derivative financial instruments. Management’s objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency and interest rates. ARRIS’s policies and practices are to use derivative financial instruments only to the extent necessary to manage exposures. ARRIS does not hold or issue derivative financial instruments for trading or speculative purposes. The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a specific risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives also may be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Cash Flow Hedges of Interest Rate Risk The Company’s senior secured credit facilities, which are comprised of (i) a “Term Loan A Facility”, (ii) a “Term Loan A-1 Facility”, (iii) a “Term Loan B-3 Facility”, and (iv) a “Revolving Credit Facility”, have variable interest rates based on LIBOR. (See Note 15 Indebtedness During the nine months ended September 30, 2018, the Company entered into new forward-starting interest rate swap arrangements which effectively will convert $1,075.0 million of the Company’s variable-rate debt based on one-month LIBOR to an aggregate fixed rate of 2.63% plus a leverage-based margin for the period beginning March 31, 2020 and ending June 30, 2022. ARRIS has designated these swaps as cash flow hedges, and the objective of these hedges is to manage the variability of cash flows in the interest payments related to the portion of the variable-rate debt designated as being hedged. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in Accumulated Other Comprehensive Income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2018, such derivatives were used to hedge the variable cash flows associated with debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the three and nine months ended September 30, 2018, approximately $0.1 million and $0.5 million in income has been recorded related to hedge ineffectiveness by the Company. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. Over the next 12 months, the Company estimates that an additional $9.6 million may be reclassified as a decrease to interest expense. The table below presents the impact the Company’s derivative financial instruments had on Consolidated Statement of Operations (in thousands): Location of AOCI into Income Three months ended September 30, Nine months ended September 30, 2018 2017 2018 2017 Gain (Loss) Recognized in OCI on Derivatives (Effective Portion) Interest expense $ 4,742 $ 340 $ 19,122 $ (394 ) Amounts Reclassified from Accumulated OCI into Income (Effective Portion) Interest expense (1,010 ) (17 ) (1,258 ) 1,777 The following table indicates the location on the Consolidated Balance Sheets in which the Company’s derivative assets and liabilities designated as hedging instruments have been recognized and the related fair values of those derivatives Balance Sheet Location September 30, 2018 December 31, 2017 Interest rate derivatives — asset derivatives Other current assets 9,560 3,590 Interest rate derivatives — asset derivatives Other assets 14,920 6,566 Interest rate derivatives — liability derivatives Other accrued liabilities — (3,053 ) Interest rate derivatives — liability derivatives Other noncurrent liabilities — (971 ) Credit-risk-related Contingent Features Each of ARRIS’s agreements with its derivative counterparties contains a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of September 30, 2018, and December 31, 2017, the fair value of derivatives, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was a net asset position of $24.5 million and $6.1 million, respectively. As of September 30, 2018, the Company has not posted any collateral related to these agreements nor has it required any of its counterparties to post collateral related to these or any other agreements. Non-designated hedges of foreign currency risk The Company has U.S. dollar functional currency entities that bill certain international customers in their local currency and foreign functional currency entities that procure in U.S. dollars. ARRIS also has certain predictable expenditures for international operations in local currency. Additionally, certain intercompany transactions are denominated in foreign currencies and subject to revaluation. To mitigate the volatility related to fluctuations in the foreign exchange rates for certain exposures, ARRIS has entered into various foreign currency contracts. As of September 30, 2018, the Company had forward contracts with notional amounts totaling 15 million euros which mature throughout 2018, forward contracts with a total notional amount of 40 million Australian dollars which mature throughout 2018 and 2019, forward contracts with notional amounts totaling 41 million Canadian dollars which mature throughout 2018 and 2019, forward contracts with notional amounts totaling 20 million British pounds which mature throughout 2018 and forward contracts with notional amounts totaling 475.4 million South African rand which mature throughout 2018 and 2019 The Company’s objective in using foreign currency derivatives are to add stability to foreign currency gains and losses recorded as other expense (income) and to manage its exposure to foreign currency movements. To accomplish this objective, the Company uses foreign currency option and foreign currency forward contracts as part of its foreign currency risk management strategy. The Company’s foreign currency derivative instruments economically hedge certain risk but The following table indicates the location on the Consolidated Balance Sheets in which the Company’s derivative assets and liabilities not designated as hedging instruments have been recognized and the related fair values of those derivatives Balance Sheet Location September 30, 2018 December 31, 2017 Foreign exchange contracts — asset derivatives Other current assets $ 3,806 $ 405 Foreign exchange contracts — liability derivatives Other accrued liabilities (516 ) (8,202 ) Foreign exchange contracts — liability derivatives Other non-current liabilities (89 ) (600 ) The change in the fair values of ARRIS’s derivatives not designated as hedging instruments recorded in the Consolidated Statements of Operations were as follows (in thousands): Statement of Operations Location Three months ended Nine months ended 2018 2017 2018 2017 Foreign exchange contracts (Gain) loss on foreign currency $ (1,606 ) $ 3,155 $ (10,488 ) $ 19,474

Guarantees and Product Warranties [Abstract]
Guarantees	Note 10. Guarantees Warranty ARRIS provides warranties of various lengths to customers based on the specific product and the terms of individual agreements. The Company provides for the estimated cost of product warranties based on historical trends, the embedded base of product in the field, failure rates, and repair costs at the time revenue is recognized. Expenses related to product defects and unusual product warranty problems are recorded in the period that the problem is identified. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its suppliers, the estimated warranty obligation could be affected by changes in ongoing product failure rates, material usage and service delivery costs incurred in correcting a product failure, as well as specific product failures outside of ARRIS’s baseline experience. If actual product failure rates, material usage or service delivery costs differ from estimates, revisions (which could be material) would be recorded to the warranty liability. The Company offers extended warranties and support service agreements on certain products. Revenue from these agreements is deferred at the time of the sale and recognized on a straight-line basis over the contract period. Costs of services performed under these types of contracts are charged to expense as incurred, which approximates the timing of the revenue stream. Information regarding the changes in ARRIS’s aggregate product warranty liabilities for the nine months ended September 30, 2018 was as follows (in thousands): Balance at December 31, 2017 $ 76,089 Warranty reserve at acquisition adjustment 827 Accruals related to warranties (including changes in assumptions) 24,958 Settlements made (in cash or in kind) (33,790 ) Balance at September 30, 2018 $ 68,084 The decline in the warranty accrual resulted from lower sales volume of CPE products, accompanied by settlement of warranty claims for amounts less than their previously recorded value.

The Fourth Amendment provided for a new Term B-3 Loan facility in the principal amount of $542.3 million, the proceeds of which (along with cash on hand) were used to repay in full the existing Term B Loan facility. Under the terms of the Fourth Amendment, the maturity date of the new Term B Loan facility remains April 26, 2024, but the new Term B Loan facility has an interest rate of LIBOR (as defined in the Credit Agreement) plus a percentage ranging from 2.00% to 2.25% for Eurocurrency Loans (as defined in the Credit Agreement) or the prime rate (as determined in accordance with the Credit Agreement) plus a percentage ranging from 1.00% to 1.25% for Base Rate Loans (as defined in the Credit Agreement), in either case depending on ARRIS’s consolidated net leverage ratio. The Fourth Amendment also increased to $500 million the amount of cash that can be used to offset indebtedness in the calculation of the consolidated net leverage ratio for purposes of determining the applicable interest rate. All other material terms of the Credit Agreement remained unchanged. On October 17, 2017, the Company entered into the Third Amendment and Consent (the “Third Amendment”) to the Credit Agreement. Pursuant to the Third Amendment, ARRIS (i) incurred “Refinancing Term A Loans” of $391 million, (ii) incurred “Refinancing Term A-1 Loans” of $1,250 million, and (iii) obtained a “Refinancing Revolving Credit Facility” of $500 million, the proceeds of which were used to refinance in full the existing Term A Loans, the existing Term A-1 Loans and the existing Revolving Credit Loans outstanding under the Credit Agreement immediately prior to the effectiveness of the Third Amendment. The existing Term B Loans were not refinanced and remained outstanding. The Third Amendment extended the maturity date of the Term A Loans and the Revolving Credit Facility to October 17, 2022. Pursuant to the Third Amendment, the Company is subject to a minimum consolidated interest coverage ratio test, which is unchanged from the Credit Agreement. In addition, the Company is subject to a maximum consolidated net leverage ratio test of not more than 4.0:1.0, subject to a step-down to 3.75:1.00 commencing with the fiscal quarter ending March 31, 2019. The amount of unrestricted cash used to offset indebtedness in the calculation of the consolidated net leverage ratio was also increased from $200 million to $500 million. The interest rates under the Third Amendment were not changed. On April 26, 2017, ARRIS entered into a Second Amendment (the “Second Amendment”) to the Credit Agreement. The Second Amendment provided for a new Term B Loan facility in the principal amount of $545 million, the proceeds of which (along with cash on hand) were used to repay the existing Term B Loan facility. Under the terms of the Second Amendment, the new Term B-2 Loan has a maturity date of April 2024 and an interest rate of LIBOR plus a percentage ranging from 2.25% to 2.50% for Eurocurrency Rate Loans (as defined in the Credit Agreement), or the prime rate plus a percentage ranging from 1.25% to 1.50% for Base Rate Loans (as defined in the Credit Agreement), in either case depending on the Company’s consolidated net leverage ratio. Interest rates on borrowings under the senior secured credit facilities are set forth in the table below. Rate As of September 30, 2018 Term A Loan LIBOR + 1.75 % 3.99% Term A-1 Loan LIBOR + 1.75 % 3.99% Term B-3 Loan LIBOR + 2.25 % 4.49% Revolving Credit Facility (1) LIBOR + 1.75 % Not Applicable (1) Includes unused commitment fee of 0.30% and letter of credit fee of 1.75% not reflected in interest rate above. The Credit Agreement provides for adjustments to the interest rates paid on the Term A Loan, Term A-1 Loan, Term B-3 Loan and Revolving Credit Facility based upon the achievement of certain leverage ratios. Borrowings under the senior secured credit facilities are secured by first-priority liens on substantially all the assets of ARRIS and certain of its present and future subsidiaries who are or become parties to, or guarantors under, the Credit Agreement governing the senior secured credit facilities. The Credit Agreement provides terms for mandatory prepayments and optional prepayments and commitment reductions. The Credit Agreement also includes events of default, which are customary for facilities of this type (with customary grace periods, as applicable), including provisions under which, upon the occurrence of an event of default, all amounts outstanding under the credit facilities may be accelerated. The Credit Agreement contains usual and customary limitations on indebtedness, liens, restricted payments, acquisitions and asset sales in the form of affirmative, negative and financial covenants, which are customary for financings of this type, including the maintenance of a minimum interest coverage ratio and a maximum leverage ratio. As of September 30, 2018, ARRIS complied with all covenants under the Credit Agreement. During the three and nine months ended September 30, 2018, the Company made mandatory payments of approximately $21.9 million and $65.6 million, respectively, related to the senior secured credit facilities.

Segment Reporting [Abstract]
Segment Information	Note 15. Segment Information The “management approach” has been used to present the following segment information. This approach is based upon the way the management of the Company organizes segments for making operating decisions and assessing performance. Financial information is reported on the basis that it is used internally by the chief operating decision maker (“CODM”) for evaluating segment performance and deciding how to allocate resources to segments. The Company’s chief executive officer has been identified as the CODM. As of January 1, 2018, the Company has changed the composition of its measurement of segment profit and loss (direct contribution) used by the Company’s chief operating decision maker. Beginning in 2018, the Company charges bonus, equity compensation and certain other costs which are now directly aligned with each of its segments within its measurement of segment profit and loss (direct contribution). These costs historically were included as part of “Corporate and Unallocated Costs”. Consequently, the Company’s segment information for the 2017 period has been restated to reflect such change. Our CODM manages the Company under three segments: · Customer Premises Equipment (“CPE”) · Network & Cloud (“N&C”) – · Enterprise Networks (“Enterprise”) — These operating segments were determined based on the nature of the products and services offered. The measures that are used to assess the reportable segment’s operating performance are sales and direct contribution. Direct contribution is defined as gross margin less direct operating expense.

Sales Information [Abstract]
Sales Information	Note 16. Sales Information Revenues from external customers are attributed to individual countries on an end-customer basis, based on domicile of the purchasing entity, if known, or the location of the customer’s headquarters if the specific purchasing entity within the customer is unknown. ARRIS sells a majority its products in the United States. The Company’s non-U.S. revenue is generated from Asia Pacific, Canada, Europe, Middle East and Latin America. Sales to customers outside of United States were approximately 40.4% and 42.1% of total sales for the three and nine months ended September 30, 2018, respectively. For the three and nine months ended September 30, 2017, sales to customers outside of United States were approximately 34.5% and 34.1%, respectively. The table below set forth our sales based on geography of our customers (in thousands): Three Months Ended , Nine Months Ended , 2018 2017 2018 2017 U.S. $ 983,377 $ 1,131,723 $ 2,869,848 $ 3,211,278 Non-U.S. Americas, excluding U.S. 302,412 283,769 886,123 832,630 Asia Pacific 100,448 105,135 300,058 265,508 EMEA 265,011 207,897 899,469 566,383 Total non-U.S. 667,871 596,801 2,085,650 1,664,521 Total sales $ 1,651,248 $ 1,728,524 $ 4,955,498 $ 4,875,799

Earnings Per Share [Abstract]
Earnings Per Share	Note 17. Earnings Per Share The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share (“EPS”) computations for the periods indicated (in thousands, except per share data): Three Months Ended September 30 , Nine Months Ended September 30 , 2018 2017 2018 2017 Basic : Net income attributable to ARRIS International plc $ 47,079 $ 88,320 $ 69,233 $ 79,558 Weighted average shares outstanding 178,106 187,064 182,132 187,878 Basic earnings per share $ 0.26 $ 0.47 $ 0.38 $ 0.42 Diluted: Net income attributable to ARRIS International plc $ 47,079 $ 88,320 $ 69,233 $ 79,558 Weighted average shares outstanding 178,106 187,064 182,132 187,878 Net effect of dilutive equity awards 1,231 1,877 1,685 2,386 Total 179,337 188,941 183,817 190,264 Diluted earnings per share $ 0.26 $ 0.47 $ 0.38 $ 0.42 Potential dilutive shares include unvested restricted and performance awards and warrants. For the three months ended September 30, 2018 and 2017, approximately 1.2 million and 1.0 million of the equity-based awards, respectively, were excluded from the computation of diluted earnings per share. For the nine months ended September 30, 2018 and 2017 approximately 1.0 million and 1.7 million of the equity-based awards, respectively, were excluded from the computation of diluted earnings per share. These exclusions are made if the exercise price of these equity-based awards is in excess of the average market price of the shares for the period, or if the Company has net losses, both of which have an anti-dilutive effect. During the nine months ended September 30, 2018, the Company issued 2.0 million ordinary shares related to the vesting of restricted shares, as compared to 2.6 million shares for the twelve months ended December 31, 2017. The warrants have a dilutive effect in those periods in which the average market price of the shares exceeds the current effective conversion price (under the treasury stock method) and are not subject to performance conditions. There is no incremental vesting in the first nine months of 2018. The dilutive effect of outstanding vested shares was immaterial. The Company has not paid cash dividends on its shares since its inception. Any future determination to pay dividends will be at the discretion of the Board of Directors and will be dependent on then-existing conditions, including the Company’s financial condition, results of operations, capital requirements, contractual and legal restrictions, business prospects and other factors that the Board considers relevant. The Credit Agreement governing the Company’s senior secured credit facilities contains restrictions on the Company’s ability to pay dividends on its ordinary shares.

Income Taxes

Income Taxes	9 Months Ended
	Sep. 30, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Note 18. Income Taxes ARRIS is subject to the U.K. statutory tax rate and a territorial corporate tax system. The U.K. statutory rate for 2018 is 19% as compared to 19.25% in 2017. The statutory rate in the U.K. decreased from 20% to 19% effective April 1, 2017. The Company’s statutory rate for 2017 represented the blended rate that was in effect for the year ended December 31, 2017 based on the 20% statutory rate that was effective for the first quarter of 2017 and the 19% rate effective for the remainder of 2017. The Tax Cuts and Jobs Act of 2017 (the “Act”) enacted on December 22, 2017 introduced significant changes to U.S. income tax law including, but not limited to, a reduction to the U.S. statutory tax rate from 35% to 21%, creation of new taxes on certain foreign-sourced earnings and certain intercompany payments, introduction of limits on interest deductibility, and increased limitations on certain executive compensation. Since the Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected during 2018, except as noted below, the Company considers the accounting of the impacts of the Act to be incomplete due to additional work necessary to (1) determine re-measurement of any changes to deferred tax assets and liabilities associated with any acquisition accounting adjustments made within the acquisition accounting measurement period and (2) assess any forthcoming guidance. Any subsequent adjustment to these amounts is recorded to tax expense in the quarter of 2018 when the analysis is complete. As the Company obtains and analyzes more information and interprets the Act and any additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service (IRS), and other standard-setting bodies, the Company may adjust the provisional amounts. Those adjustments may materially affect the provision for income taxes and effective tax rate in the period in which the adjustments are made. The only significant adjustments made during the nine months ended September 30, 2018 were a direct result of the acquisition accounting adjustments made during the quarters. As a result of the change to the fair value of certain assets and liabilities, the gross deferred tax amounts associated with those assets and liabilities also changed. The fair value adjustments are as of the Ruckus acquisition date, December 1, 2017, resulting in the gross deferred tax impacts being measured at the applicable enacted tax rate of 35% on that date. These deferred tax impacts were then remeasured to 21% to reflect the enacted rate as of December 22, 2017. As a result of these acquisition accounting measurement period adjustments, the Company recorded discrete tax benefit of $2.9 million during the nine months ended September 30, 2018. No adjustments were made to fair value, and therefore there were no discrete tax impacts during the three months ended September 30, 2018. During the third quarter of 2018, the Company finalized the impact of the one-time transition tax for the deemed repatriation of the earnings of the ARRIS controlled foreign corporations. The finalization of the 2017 earnings and profits amounts increased the transition tax from $(0.2) million benefit to $0.3 million tax expense. The Company has recorded current tax on its global intangible low-taxed income (“GILTI”) relative to the 2018 operations and has elected to account for GILTI as period costs when incurred. The Company will complete our analysis within the measurement period in accordance with Staff Accounting Bulletin No. 118. For the period ended September 30, 2018, the Company changed its indefinite reinvestment assertion to reflect deferred income taxes on a portion of the unremitted earnings of certain subsidiaries. This change resulted in an additional $2.4 million of tax expense. The Company reported the following operating results for the periods presented (in thousands): Three Months Ended September 30 Nine Months Ended , 2018 2017 2018 2017 Income before income taxes $ 30,156 $ 72,504 $ 41,468 $ 61,646 Income tax benefit (15,652 ) (14,311 ) (22,106 ) (12,613 ) Effective income tax rate (51.9 )% (19.7 )% (53.3 )% (20.5 )% The Company’s effective income tax rate fluctuates based on, among other factors, the level and location of income. The difference between the U.K. federal statutory income tax rate, 19% and 19.25%, respectively, and our effective income tax rate for the 2018 and 2017 periods is primarily due to the benefits of other foreign income tax regimes and the U.S. federal research and development credits . The Company’s effective income tax rate for the nine months ended September 30, 2018 was impacted by $1.5 million of expense related to excess book deductions for stock based compensation, $4.7 million of expense related to changes in permanent reinvestment assertions, offset by $12.4 million of benefit related to the release of uncertain tax positions due to settlement of audits and the expiration of statute of limitations, $2.8 million of benefit related to the effects of tax rate changes in the US, and $4.2 million of benefit related to an internal restructuring to move certain Ruckus Networks intangible property into the U.S. The Company’s effective income tax rate for the nine months ended September 30, 2017 was impacted by $8.0 million of expense related to the intra-entity sale of an asset, offset by $9.8 million of benefit related to a decrease of interest related to uncertain tax positions and the release of uncertain tax positions due to settlement of audits and expiration of statute of limitations, and a $1.2 million of benefit related to excess tax deductions for stock-based compensation.

Repurchases of ARRIS Shares The table below sets forth the purchases of ARRIS shares for the quarter ended September 30, 2018: Period Total (1) Average Total Number of Approximate July 2018 2,189,251 $ 25.53 1,957,982 350,010 August 2018 3,944,817 $ 24.84 3,941,214 252,103 September 2018 (2) 2,454,677 $ 26.16 2,454,677 562,894 (1) An aggregate of 234,872 shares shown in the table above were subject to equity awards that were cancelled for cash to satisfy employee minimum tax withholding obligations that arose on the vesting of the applicable restricted stock units. (2) Includes an aggregate of 210,654 shares (approximately $5.5 million) pending settlement as of September 30, 2018. Upon completing the combination in connection with the Pace acquisition, ARRIS International plc conducted a court-approved process in accordance with section 641(1)(b) of the U.K. Companies Act 2006, pursuant to which the Company reduced its stated share capital and thereby increased its distributable reserves or excess capital out of which ARRIS may legally pay dividends or repurchase shares. Distributable reserves are not linked to a U.S. GAAP reported amount. In 2016, the Company’s Board of Directors approved a $300 million share repurchase authorization replacing all prior programs. In early 2017, the Board authorized an additional $300 million for share repurchases. In March 2018, the Board authorized an additional $300 million for repurchases and an additional $375 million again in August 2018. During the first quarter of 2018, the Company repurchased 1.0 million shares of its ordinary shares for $25.0 million at an average share price of $25.35. During the second quarter of 2018, the Company repurchased 4.0 million shares of its ordinary shares for $99.9 million at an average share price of $25.29. During the third quarter of 2018, the Company repurchased 8.4 million shares of its ordinary shares for $212.2 million at an average share price of $25.40. The remaining authorized amount for share repurchases under these repurchase authorizations was $562.9 million as of September 30, 2018. Since the end of the third quarter through November 8, 2018, the Company has repurchased an additional 0.6 million ordinary shares for approximately $16.0 million. The remaining authorized amount for share repurchases under these repurchase authorizations was $546.9 million as of November 8, 2018. Unless terminated earlier by a Board resolution, this repurchase authorization will expire when ARRIS has used all authorized funds for repurchase. However, U.K. law also generally prohibits a company from repurchasing its own shares through “off market purchases” without prior approval of shareholders when such company is not traded on a recognized investment exchange in the U.K. This shareholder approval lasts for a maximum period of five years. Prior to and in connection with the Pace combination, the Company obtained approval to purchase its own shares. This authority to repurchase shares terminates in January 2021, unless otherwise reapproved by the Company’s shareholders.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 22. Commitments and Contingencies Legal Proceedings The Company accrues a liability for legal contingencies when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of the loss. The Company reviews these accruals and adjusts them to reflect ongoing negotiations, settlements, rulings, advice of legal counsel and other relevant information. To the extent new information is obtained and the Company’s views on the probable outcomes of claims, suits, assessments, investigations or legal proceedings change, changes in the Company’s accrued liabilities would be recorded in the period in which such determinations are made. Unless noted otherwise, the amount of liability is not probable, or the amount cannot be reasonably estimated; and, therefore, accruals have not been made. Due to the nature of the Company’s business, it is subject to patent infringement claims, including current suits against it or one or more of its wholly-owned subsidiaries, or one or more of our customers who may seek indemnification from us, alleging infringement by various Company products and services. The Company believes that it has meritorious defenses to the allegation made in its pending cases and intends to vigorously defend these lawsuits; however, it is currently unable to determine the ultimate outcome of these or similar matters. Accordingly, with respect to these proceedings, we are currently unable to reasonably estimate the possible loss or range of possible losses. In addition, the Company is a defendant in various litigation matters generally arising out of the normal course of business. (See Part II, Item 1 “Legal Proceedings” for additional details)
