Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies (a) Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries and consolidated venture in which the Company owns more than 50% of the outstanding voting shares of the entity. Intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP), and our reporting currency is the United States Dollar (USD). (b) Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. (c) Reclassifications Certain prior year amounts in the financial statements and notes have been reclassified to conform to the fiscal year 2018 presentation. (d) Cash, Cash Equivalents, and Investments Cash and cash equivalents ARRIS’s cash and excess cash are primarily held in demand deposit accounts and money market accounts. The Company classifies all investments that are readily convertible to known amounts of cash and have stated maturities of three months or less from the date of purchase as cash equivalents and those with stated maturities of greater than three months as marketable securities. Marketable securities The Company determines the appropriate classification of our investments in marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its marketable debt securities as available-for-sale. These securities are carried at fair value, and the unrealized gains and losses, net of taxes, are reported as a component of stockholders’ equity, except for unrealized losses determined to be other-than-temporary, which are recorded within loss on investments in the Consolidated Statements of Income. The Company determines any realized gains or losses on the sale of marketable debt securities on a specific identification method and records such gains and losses as a gain or loss on investment in the Consolidated Statements of Income. Non-marketable investments The Company accounts for non-marketable equity investments through which the Company exercises significant influence but does not have control over the investee under the equity method. Beginning on January 1, 2018, non-marketable equity securities not accounted for under the equity method are either carried at fair value or under the measurement alternative upon the adoption of accounting standard Recognition and Measurement of Financial Assets and Financial Liabilities Impairment of investments The Company periodically reviews its debt and equity investments for impairment. For debt securities the Company considers the duration, severity and the reason for the decline in security value; whether it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or if the amortized cost basis cannot be recovered as a result of credit losses. If any impairment is considered other-than-temporary, the Company will write down the security to its fair value and record the corresponding charge as a loss on investments. For equity securities the Company considers impairment indicators such as negative changes in industry and market conditions, financial performance, business prospects, and other relevant events and factors. If indicators exist and the fair value of the security is below the carrying amount, the Company writes down the security to fair value. (e) Accounts Receivable and Allowance for Doubtful Accounts and Sales Returns Accounts receivable are stated at amounts owed by the customers, net of allowance for doubtful accounts, sales returns and allowances. ARRIS establishes a reserve for doubtful accounts based upon the historical experience and leading market indicators in collecting accounts receivable. A majority of the accounts receivable are from a few large cable system operators and telecommunication companies, either with investment rated debt outstanding or with substantial financial resources and have favorable payment histories. If ARRIS was to have a collection problem with one of its major customers, it is possible the reserve will not be sufficient. ARRIS calculates the reserve for uncollectible accounts using a model that considers customer payment history, recent customer press releases, bankruptcy filings, if any, Dun & Bradstreet reports, and financial statement reviews. The calculation is reviewed by management to assess whether there needs to be an adjustment to the reserve for uncollectible accounts. The reserve is established through a charge to the provision and represents amounts of current and past due customer receivable balances of which management deems a loss to be both probable and estimable. Accounts receivable are charged to the allowance when determined to be no longer collectible. ARRIS also establishes a reserve for sales returns and allowances. The reserve is an estimate of the impact of potential returns based upon historic trends. The following table represents a summary of the changes in the reserve for allowance for doubtful accounts, and sales returns and allowances for fiscal 2018, 2017 and 2016 (in thousands): 2018 2017 2016 Balance at beginning of fiscal year $ 10,230 $ 15,253 $ 9,975 (Credit) charges to expenses (462 ) (566 ) 1,386 (Write-offs) recoveries, net (2,326 ) (4,457 ) 3,892 Balance at end of fiscal year $ 7,442 $ 10,230 $ 15,253 (f) Inventories Inventories are stated at the lower of cost or net realizable value. Inventory cost is determined on a first-in, first-out basis. The cost of work-in-process and finished goods is comprised of material, labor, and overhead. (g) Revenue recognition On January 1, 2018, the Company adopted the new accounting standard Revenue from Contracts with Customers using the modified retrospective transition method. The Company has elected to apply the new standard to contracts that were considered “open” as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new accounting standard, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under previous guidance. ARRIS generates revenue from of 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 the amount of consideration expected to be received. 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 performance obligations typically include proprietary operating system software, which isn’t considered separately identifiable. Therefore, ARRIS’s equipment and their related software are considered one 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 are recognized over time because the customer simultaneously receives and consumes the benefits of the service as the services are performed. · 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 – 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 270 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 sales incentive programs, the Company can reasonably estimate its 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. (h) Shipping and Handling Fees Shipping and handling costs for the years ended December 31, 2018, 2017, and 2016 were approximately $13.2 million, $12.6 million and $4.3 million, respectively, and are classified in cost of sales. (i) Taxes Collected from Customers and Remitted to Governmental Authorities Taxes assessed by a government authority that are both imposed on and concurrent with specific revenue transactions between us and our customers are presented on a net basis in our Consolidated Statements of Income. (j) Depreciation of Property, Plant and Equipment The Company provides for depreciation of property, plant and equipment on the straight-line basis over estimated useful lives of 10 to 40 years for buildings and improvements, 2 to 10 years for machinery and equipment, and the shorter of the term of the lease or useful life for leasehold improvements. Included in depreciation expense is the amortization of landlord funded tenant improvements which amounted to $14.0 million in 2018, $12.1 million in 2017 and $6.6 million in 2016. Depreciation expense, including amortization of capital leases, for the years ended December 31, 2018, 2017, and 2016 was approximately $83.7 million, $88.2 million, and $90.6 million, respectively. See Note 13 Property, Plant and Equipment (k) Goodwill and Purchased Intangible Assets Goodwill is tested for impairment annually as of October 1st, or when an indicator of impairment exists. As of October 1, 2017, we early adopted Accounting Standards Update (“ASU”) 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 eliminated Step 2 of the goodwill impairment test in which an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities. The standard does not change the guidance on completing Step 1 of the goodwill impairment test. In accordance with the new standard, we compare the fair value of our reporting units with the carrying amount, including goodwill. The Company recognizes an impairment charge for the amount by which the carrying amount exceeds a reporting unit’s fair value, as applicable. Purchased intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. Useful lives of identifiable intangible assets are determined after considering the specific facts and circumstances related to each intangible asset. Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their useful lives, generally ranging from 1 to 13 years. Certain intangible assets are being amortized using an accelerated method, as an accelerated method best approximates the distribution of cash flows generated by the intangible assets. See “Long-Lived Assets” for the Company’s policy regarding impairment testing of purchased intangible assets with finite lives. Purchased intangible assets with indefinite lives are assessed for potential impairment annually or when events or circumstances indicate that their carrying amounts might be impaired. See Note 6 Goodwill and Other Intangible Assets Long-Lived Assets Long-lived assets, including property, plant and equipment and intangible assets with finite lives, that are held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability of long-lived assets is based on an estimate of the undiscounted future cash flows resulting from the use of the asset and its eventual disposition. To test for recovery, the Company groups assets (an “asset group”) in a manner that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. If the sum of the expected future cash flows (undiscounted and pre-tax based upon policy decision) is less than the carrying amount, the Company recognizes an impairment loss. The impairment loss recognized is the amount by which the carrying amount of the asset or asset group exceeds the fair value. A variety of methodologies are used to determine the fair value of these assets, including discounted cash flow models, which are consistent with the assumptions the Company believes hypothetical marketplace participants would use. Measurement of an impairment loss for long-lived assets that management expects to hold and use is based on the difference between the fair value of the asset and its carrying value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. (l) Advertising and Sales Promotion Advertising and sales promotion costs are expensed as incurred. Advertising and sales promotion expense was approximately $23.5 million, $17.5 million, and $19.6 million for the years ended December 31, 2018, 2017 and 2016, respectively. (m) Research and Development Research and development (“R&D”) costs are expensed as incurred. The expenditures include compensation costs, materials, other direct expenses, and an allocation of information technology, telecommunications, and facilities costs. (n) Warranty ARRIS provides warranties of various lengths to customers based on the specific product and the terms of individual agreements. For further discussion, see Note 10 Guarantees (o) Income Taxes ARRIS uses the liability method of accounting for income taxes, which requires recognition of temporary differences between financial statement and income tax bases of assets and liabilities, measured by enacted tax rates. If necessary, the measurement of deferred tax assets is reduced by a valuation allowance to an amount that is more likely than not to be realized based on available evidence. ARRIS reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company elects to account for Global Intangible Low-Taxed Income (“GILTI”) in the period the tax is incurred. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in Income tax (benefit) expense in the Consolidated Statements of Income. See Note 19 Income Taxes (p) Foreign Currency A significant portion of the Company’s products are manufactured or assembled in Brazil, China, Mexico and Taiwan, and we have research and development centers in Canada, China, France, India, Ireland, Israel, Singapore, Sweden, Taiwan and United Kingdom. Sales into international markets have been and are expected in the future to be an important part of the Company’s business. These foreign operations are subject to the usual risks inherent in conducting business abroad, including risks with respect to currency exchange rates, economic and political destabilization, restrictive actions and taxation by foreign governments, nationalization, the laws and policies of the United States affecting trade, foreign investment and loans, and foreign tax laws. The financial position and results of operations of certain of the Company’s international subsidiaries are measured using the local currency as the functional currency. Revenues and expenses of these subsidiaries are translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities of these subsidiaries are translated at the exchange rates as of the balance sheet date. Translation gains and losses are recorded in Accumulated other comprehensive (loss) income. ARRIS has certain international customers who are billed in their local currency and certain international operations 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. The Company enters into forward or currency option contracts based on a percentage of expected foreign currency exposures. The percentage can vary, based on the predictability of the exposures denominated in the foreign currency. See Note 9 Derivative Instruments and Hedging Activities (q) Stock-Based Compensation See Note 20 Stock-Based Compensation (r) Concentrations of Credit Risk Financial instruments that potentially subject ARRIS to concentrations of credit risk consist principally of cash, cash equivalents and short-term investments, accounts receivable and derivatives. ARRIS places its temporary cash investments with high credit quality financial institutions. Concentrations with respect to accounts receivable occur as the Company sells primarily to large, well- established companies, including companies outside of the United States. The Company’s credit policy generally does not require collateral from its customers. ARRIS closely monitors extensions of credit to other parties and, where necessary, utilizes common financial instruments to mitigate risk or requires cash on delivery terms. Overall financial strategies and the effect of using a hedge are reviewed periodically. As of December 31, 2018, two customers represented 13% and 12% of total accounts receivable. As of December 31, 2017, two customers represented 19% and 14% of total accounts receivable. (s) Fair Value 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. In order 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. Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments: • Cash, cash equivalents, and short-term investments: The carrying amounts reported in the Consolidated Balance Sheets for cash, cash equivalents, and short-term investments approximate their fair values. • Accounts receivable and accounts payable: The carrying amounts reported in the balance sheet for accounts receivable and accounts payable approximate their fair values. • Marketable securities: The fair values for available-for-sale equity securities are based on quoted market prices or observable prices based on inputs not in active markets but corroborated by market data. • Non-marketable securities: Non-marketable equity securities are subject to a periodic impairment review; however, there are no open-market valuations, and the impairment analysis requires significant judgment. This analysis includes assessment of the investee’s financial condition, the business outlook for its products and technology, its projected results and cash flow, recent rounds of financing, and the likelihood of obtaining subsequent rounds of financing. • Senior secured credit facilities: Comprised of term loans and a revolving credit facility of which the outstanding principal amount approximates fair value because of interest-bearing rates that are adjusted periodically, analysis of recent market conditions, prevailing interest rates and other Company specific factors. • Derivative instruments: The carrying amounts reported in the balance sheet for derivative financial instruments reflect their estimated fair values, as the valuation inputs are based on quoted prices and market observable data of similar instruments. (t) Computer Software Internal-use software The Company capitalizes costs associated with internally developed and/or purchased software systems for internal use that have reached the application development stage and meet recoverability tests. Capitalized costs include external direct costs of materials and services utilized in developing or obtaining internal-use software and payroll and payroll-related expenses for employees who are directly associated with and devote time to the internal-use software project. Capitalization of such costs begins when the preliminary project stage is complete and ceases no later than the point at which the project is substantially complete and ready for its intended purpose. These capitalized costs are amortized on a straight-line basis over periods of two to seven years, beginning when the asset is ready for its intended use. Capitalized costs are included in property, plant, and equipment on the Consolidated Balance Sheets. External-use software Research and development costs are charged to expense as incurred. ARRIS generally has not capitalized any such development costs because the costs incurred between the attainment of technological feasibility for the related software product through the date when the product is available for general release to customers has been insignificant. Cloud Computing Arrangements Implementation costs incurred in a cloud computing arrangement that is a service contract are capitalized similar to implementation costs incurred to develop or obtain internal-use software. Amortization is computed over the term of the hosting arrangement. As of December 31, 2018, implementation costs of $11.9 million associated with cloud computing arrangements has been capitalized and is included in Other Assets in the Consolidated Balance Sheets. (u) Comprehensive (Loss) Income The components of comprehensive (loss) income include net income (loss), unrealized gains (losses) on available-for-sale debt securities, unrealized gains (losses) on certain derivative instruments, change in pension liabilities, net of tax, if applicable and foreign currency translation adjustments. (v) Warrants The Company has outstanding warrants with certain customers to purchase ARRIS’s ordinary shares. Vesting of the warrants is subject to certain purchase volume commitments by the customers. Under applicable accounting guidance, if the vesting of a tranche of the warrants is probable, the Company is required to mark-to-market the fair value of the warrant until it vests, and any increase in the fair value is treated as a reduction in revenues from sales to the customers.

Accounting Changes and Error Corrections [Abstract]
Impact of Recently Issued Accounting Standards	Note 3. Impact of Recently Issued 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 4 Revenue from Contracts 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 (loss) income. This guidance is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. ARRIS adopted the standard on January 1, 2018 by recording a cumulative-effect adjustment as of the beginning of the year. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position and results of operations. 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 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 is effective for the Company for annual periods beginning after December 15, 2017. The adoption of this guidance did not have a material impact on the Company’s consolidated financial position and results of operations. The future 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 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 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 24) will be reported on the Consolidated Balance Sheets upon adoption. 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 (loss) income to Accumulated deficit. 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. The Company is currently assessing the potential impact of the adoption of this standard on its Consolidated Financial Statements. 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 4. Revenue from Contracts with Customers On January 1, 2018, the Company adopted the new accounting standard Revenue from Contracts with Customers using the modified retrospective transition method. The Company has elected to apply the new standard to contracts that were considered “open” as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new accounting standard, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under previous guidance. Upon adoption, an initial cumulative effect adjustment of $1.8 million increase was recorded to opening accumulated deficit and a $2.7 million increase in shareholder’s equity attributable to noncontrolling interest. Disaggregation of Revenue The following table summarizes the revenues from contracts with customers by major product line (in thousands): December 31, 2018 CPE: Broadband CPE $ 1,643,152 Video CPE 2,280,742 Sub-total 3,923,894 Network & Cloud: Networks 1,850,416 Software and services 306,161 Sub-total 2,156,577 Enterprise Networks: Enterprise Networks 675,352 Other: Other (13,183 ) Total net sales $ 6,742,640 Customer Premises Equipment — The CPE segment’s product solutions include Broadband products, such as DSL and DOCSIS gateways and modems, and Video products, such as video gateways, clients and set-tops, that enable service providers to offer voice, video and high-speed data services to residential and business subscribers. Network & Cloud — The N&C segment’s product solutions include cable modem termination system, video infrastructure, distribution and transmission equipment and cloud solutions that enable facility-based service providers to construct a state-of-the-art residential and metro distribution network. The portfolio also includes a full suite of global services that offer technical support, professional services and system integration offerings to enable solution sales of ARRIS’s end-to-end product portfolio. Enterprise Networks — The Enterprise Networks segment focuses on enabling constant, wireless and wired connectivity across complex and varied networking environments through its array of access points, controllers and switches along with technical support, analytical tools and professional services needed to support those networks. It offers dedicated engineering, sales and marketing resources to serve customers across a spectrum of enterprises—including hospitality, education, smart cities, government, venues, service providers and more. Other — Other includes adjustments related to acquisition accounting impacts related to deferred revenue The following table summarizes the revenues from contracts with customers by geographic areas (in thousands): December 31, 2018 CPE N&C Enterprise Other (1) Total Domestic – U.S. $ 2,201,912 $ 1,369,695 $ 408,971 $ (7,331 ) $ 3,973,247 Americas, excluding U.S. 793,203 378,223 10,910 (47 ) 1,182,289 Asia Pacific 133,480 186,982 110,622 (39 ) 431,045 EMEA 795,299 221,677 144,849 (5,766 ) 1,156,059 Total international 1,721,982 786,882 266,381 (5,852 ) 2,769,393 Total net revenues $ 3,923,894 $ 2,156,577 $ 675,352 $ (13,183 ) $ 6,742,640 (1) Adjustments include acquisition accounting impacts related to deferred revenue Impact of New Revenue Guidance on Financial Statement Line Items The following table compares the reported Consolidated Balance Sheets and Consolidated Statements of Income, as of and for the year ended December 31, 2018, to the pro-forma amounts had the previous guidance been in effect (in thousands): As Reported December 31, 2018 Pro forma – as if previous accounting guidance was in effect Assets Accounts receivable $ 1,225,975 $ 1,210,288 Other current assets 144,251 144,187 Deferred incomes taxes 175,405 172,967 Liabilities Deferred revenue (current and non-current) $ 169,998 $ 169,426 As Reported December 31, 2018 Pro forma – as if previous accounting guidance was in effect Revenues Net sales $ 6,742,640 $ 6,727,525 Costs and expenses Cost of sales 4,823,781 4,823,845 Income tax benefit (24,344 ) (21,905 ) Consolidated net income 107,286 89,668 Net loss attributable to non-controlling interest (6,454 ) (7,282 ) Net income attributable to ARRIS International plc 113,740 96,950 Net income per ordinary share: Basic $ 0.63 $ 0.54 Diluted $ 0.62 $ 0.53 Pro-forma net sales were $15.1 million lower than reported net sales in the Consolidated Statements of Income for the year ended December 31, 2018 largely due to the timing of license revenue that is currently being recognized upon transfer of control of the license as opposed to recognizing ratably over the license term. Other Contract Assets and Liabilities The unbilled receivables are included in Accounts Receivable on the Consolidated Balance Sheets. As of December 31, 2018, the Company has unbilled receivables of $29.7 million. The following table summarizes the changes in deferred revenue for the year ended of December 31, 2018 (in thousands): Opening balance at January 1, 2018 $ 168,757 Deferral of revenue 166,756 Recognition of unearned revenue (164,545 ) Other (970 ) Balance at December 31, 2018 $ 169,998 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 $64.1 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 Acquisition	Note 5. Business Acquisitions 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 consideration transferred was approximately $762.2 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. With this acquisition, ARRIS expanded 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 goodwill of $289.0 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. The Company finalized the accounting for business combination in the fourth quarter of 2018 and goodwill has been assigned to our new Enterprise Networks reporting unit. Goodwill of $5.8 million 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 Working capital adjustments (15,219 ) Non-cash consideration (1) (2,359 ) Total consideration transferred $ 762,165 (1) Non-cash consideration represents $2.4 million settlement of preexisting payables and receivables between Ruckus Networks and ARRIS. Total consideration excludes $61.5 million paid to Broadcom for the cash settlement of stock-based awards for which vesting was accelerated as contemplated in the purchase agreement. This was expensed in the fourth quarter of 2017. The following is a summary of the estimated fair values of the net assets acquired (in thousands): Amounts Recognized Total consideration transferred $ 762,165 Cash and cash equivalents 18,958 Accounts receivable 26,022 Inventories 48,436 Prepaids and other 3,792 Property, plant & equipment 31,863 Intangible assets 500,700 Other assets 6,852 Accounts payable and accrued liabilities (15,693 ) Other current liabilities (11,654 ) Deferred revenue (46,748 ) Noncurrent deferred income tax liabilities, net (81,928 ) Other noncurrent liabilities (7,408 ) Net assets acquired 473,192 Goodwill $ 288,973 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. During the fourth quarter of 2018, the Company completed the accounting for the aforementioned business combination. The $500.7 million of acquired intangible assets are as follows (in thousands): Estimated Fair value Estimated Weighted Average Life (years) Technology and patents $ 220,900 5.4 Customer contracts and relationships 197,100 10.0 Tradenames 55,400 indefinite Trademarks and tradenames 10,800 10.0 Backlog 16,500 0.4 Total estimated fair value of intangible assets $ 500,700 The fair value of trade accounts receivable is $26.0 million with the gross contractual amount being $26.9 million. The Company expects $0.9 million to be uncollectible. The Company incurred acquisition related costs of $1.3 million during 2018. This amount was expensed by the Company as incurred and is included in the Consolidated Statements of Income in the line item titled “Integration, acquisition, restructuring and other costs, net”. The Ruckus Networks business contributed revenues of approximately $721.1 million to our consolidated results from the date of acquisition through December 31, 2018. Proposed Transaction with CommScope On November 8, 2018, ARRIS and CommScope Holding Company, Inc. entered into a Bid Conduct Agreement whereby CommScope agreed to acquire ARRIS in an all-cash transaction for $31.75 per share or a total purchase price of approximately $7.4 billion, including repayment of debt. In addition, The Carlyle Group, a global alternative asset manager, plans to participate in the acquisition and reestablishes an ownership position in CommScope through a $1 billion minority equity investment as part of CommScope's financing of the transaction. The combined company is expected to drive profitable growth in new markets, shape the future of wired and wireless communications, and position the new company to benefit from key industry trends, including network convergence, fiber and mobility everywhere, 5G, Internet of Things and rapidly changing network and technology architectures. The consummation of the Acquisition is subject to various closing conditions, including, among other things, (i) the receipt of certain approvals of our shareholders, (ii) the sanction of the Scheme by the High Court of Justice of England and Wales, (iii) the receipt of certain required regulatory approvals or lapse of certain review periods with respect thereto, including those in the U.S. and European Union, Chile, Mexico, Russia and South Africa, (iv) the absence of a Company Material Adverse Effect (as defined in the Acquisition Agreement), (v) the accuracy of representations and warranties (subject, in certain cases, to certain materiality or Company Material Adverse Effect qualifiers, as applicable) and (vi) the absence of legal restraints prohibiting or restraining the Acquisition. ARRIS’s shareholders approved the Acquisition on February 1, 2019 and regulatory approvals have been received, or the review period has lapsed, in the European Union, United States, Russia and South Africa. The parties expect to complete the Acquisition in the first half of 2019. Acquisition related costs of $8.4 million have been incurred during 2018. This amount was expensed by the Company as incurred and is included in the Consolidated Statements of Income in the line item titled “Integration, acquisition, restructuring and other costs, net”.

The Company also recorded a partial impairment of goodwill of $3.4 million related to its Cloud TV reporting unit, respectively, of which $1.2 million is attributable to the noncontrolling interest. This impairment was a result of the indirect effect of a change in accounting principle related to the adoption of new accounting standard Revenue from Contracts with Customers As of December 31, 2018, Cloud and Services reporting unit, which is included in the N&C segment, had a negative carrying amount of net assets of $(15.5) million. As of December 31, 2018, remaining goodwill allocated to this reporting unit was $49.9 million. During 2017, as a result of a change in strategy for our Cloud TV reporting unit associated with the ActiveVideo acquisition, the Company expected lower future projected cash flows for the business, and as such, the Company recorded a partial impairment of $51.2 million for the amount by which the Cloud TV reporting unit carrying amount exceeded its fair value of which $17.9 million is attributable to noncontrolling interest.

These investments are stated at fair value as required by the applicable accounting guidance. Unrealized gains and losses on available-for-sale debt securities are included in the Consolidated Balance Sheets as a component of Accumulated other comprehensive (loss) income. As of December 31, 2017, the available-for-sale debt securities have been in an unrealized loss position for less than 12 months. As of December 31, 2018, the contractual maturity of our available for sale debt securities was within 1 year. Investments in the above table are included in short-term investments on the Consolidated Balance Sheets. Realized gains and losses on investments are included in earnings and are derived using the specific identification method for determining the cost of securities sold. Long-Term Investments: The following table summarizes the Company’s long-term investments by significant categories as of December 31, 2018 and December 31, 2017 (in thousands): As of December 31, 2018 As of December 31, 2017 Equity investments: Marketable equity securities $ 5,562 $ 5,718 Non-marketable equity securities 9,987 10,092 Equity method investments 12,507 22,021 Other investments 17,239 33,251 Total $ 45,295 $ 71,082 Equity investments The following discusses the Company’s marketable equity securities, non-marketable equity securities, realized and unrealized gains and losses on marketable and non-marketable equity securities, as well as its equity method investments. Marketable equity securities Marketable equity securities are deferred compensation plan assets related to non-qualified deferred compensation plans for certain executives, including money market funds and mutual funds with readily determinable values which are accounted for at fair value. Prior to January 1, 2018, the Company accounted for its marketable equity securities at fair value with unrealized gains and losses recognized in Accumulated other comprehensive (loss) income on the Consolidated Balance Sheets. As of December 31, 2017, investments had an amortized cost of $5.1 million and unrealized gains (loss) of $0.8 million and $(0.1) million, respectively. Realized gains and losses on marketable equity securities sold or impaired were recognized in Loss on investments in the Consolidated Statements of Income. On January 1, 2018, the Company adopted the accounting standard Recognition and Measurement of Financial Assets and Financial Liabilities As of December 31, 2018, and December 31, 2017, the Company’s marketable equity securities have been in an unrealized loss position for less than 12 months. The classification of marketable equity securities as current or non-current is dependent upon management’s intended holding period, the security’s maturity date and liquidity consideration based on market conditions. If management intends to hold the securities for longer than one year as of the balance sheet date, they are classified as non-current. The sale and/or maturity of marketable equity securities resulted in the following activity (in thousands): Years Ended December 31, 2018 2017 2016 Proceeds from sales $ 79,473 $ 165,301 $ 25,931 Gross gains 5 16 33 Gross losses — — — Non-marketable equity securities Non-marketable equity securities are investments in privately held companies without readily determinable market values. Prior to January 1, 2018, the Company accounted for its non-marketable equity securities at cost less impairment. Realized gains and losses on non-marketable securities sold or impaired were included in loss on investments, included in the Consolidated Statements of Income. On January 1, 2018, Company adopted the accounting standard Recognition and Measurement of Financial Assets and Financial Liabilities There have been no adjustments to the carrying value of investments resulting from impairments or observable price changes in 2018. For the year ended December 31, 2017, the Company concluded that one private company had indicators of impairment, as the cost basis exceeded the fair value of the investment, resulting in an other-than-temporary impairment charge of $2.8 million. These charges are reflected in “Loss on investments” in the Consolidated Statements of Income. Equity Method Investments The Company owns certain investments in limited liability companies and partnerships that are accounted for under the equity method, as the Company has significant influence over operating and financial policies of the investee companies. Our share of gains and losses in equity method investments including impairment are included in loss on investments in the Consolidated Statements of Income. Due to the timing of receiving financial information from these limited liability companies and partnerships, the results are reported on a one quarter lag. The following table summarizes the ownership structure and ownership percentage of the non-consolidated investments as of December 31, 2018, accounted for using the equity method. Name of Investee Ownership Structure % Ownership MPEG LA Limited Liability Company 8.4 % Music Choice Limited Liability Partnership 18.2 % Conditional Access Licensing (“CAL”) Limited Liability Company 49.0 % Other Investments The Company holds investments in certain life insurance contracts. The Company determined the fair value to be the amount that could be realized under the insurance contract as of each reporting period. The changes in the fair value of these contracts are reflected in “Loss on investments” in the Consolidated Statements of Income.

Fair Value Measurements	Note 8. Fair Value Measurements The following table presents the Company’s investment assets (excluding non-marketable equity investments) and derivatives measured at fair value on a recurring basis as of December 31, 2018 and 2017 (in thousands): December 31, 2018 Level 1 Level 2 Level 3 Total Certificates of deposit (foreign) $ — $ 5,538 $ — $ 5,538 Marketable equity securities 62 5,500 — 5,562 Interest rate derivatives — asset derivatives — 10,976 — 10,976 Interest rate derivatives — liability derivatives — (6,088 ) — (6,088 ) Foreign currency contracts — asset position — 4,442 — 4,442 Foreign currency contracts — liability position — (405 ) — (405 ) December 31, 2017 Level 1 Level 2 Level 3 Total Certificates of deposit (foreign) $ — $ 12,809 $ — $ 12,809 Corporate bonds — 11,065 — 11,065 Marketable equity securities 117 5,601 — 5,718 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 ) All of the Company’s short-term and long-term investments (excluding non-marketable equity investments) at December 31, 2018 are classified within Level 1 or Level 2 of the fair value hierarchy as they are valued using quoted market prices, market prices for similar securities, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include the Company’s investment in money market funds, mutual funds and municipal bonds. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs include corporate obligations and bonds, commercial paper and certificates of deposit. Such instruments are classified within Level 2 of the fair value hierarchy. In addition to the financial instruments included in the above table, certain nonfinancial assets and liabilities are to be 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 year ended December 31, 2018, the Company recorded partial impairment of goodwill of $3.4 million related to its 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 6 Goodwill and Intangible Assets The Company believes the principal amount of the debt as of December 31, 2018 approximated the 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 9. 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 relating to certain of these exposures, the Company enters into 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 particular 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 16 Indebtedness 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 (loss) 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 year ended December 31, 2018, approximately $0.5 million in income has been recorded related to hedge ineffectiveness by the Company. During the years ended December 31, 2017 and 2016, no expense has been recorded related to hedge ineffectiveness by the Company. Amounts reported in Accumulated other comprehensive (loss) 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 $8.8 million may be reclassified as a decrease to interest expense. The table below presents the impact of the Company’s derivative financial instruments had on Consolidated Statements of Income (in thousands): Location of Gain(Loss) Years Ended Reclassified from December 31, AOCI into Income 2018 2017 2016 Gain Recognized in OCI on Derivatives (Effective Portion) Interest expense $ 1,121 $ 5,587 $ 2,103 Amounts Reclassified from Accumulated OCI into Income (Effective Portion) Interest expense (2,851 ) 1,663 7,512 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 (in thousands): Balance Sheet Location December 31, 2018 December 31, 2017 Interest rate derivatives — asset derivatives Other current assets 8,788 3,590 Interest rate derivatives — asset derivatives Other assets 2,188 6,566 Interest rate derivatives — liability derivatives Other accrued liabilities — (3,053 ) Interest rate derivatives — liability derivatives Other noncurrent liabilities (6,088 ) (971 ) Credit-risk-related contingent features Each of ARRIS’s agreements with its derivative counterparties contain 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 December 31, 2018 and 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 $4.6 million and $6.1 million, respectively. As of December 31, 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 subsidiaries 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 December 31, 2018, the Company had forward contracts with notional amounts totaling 60 million euros which mature throughout 2019, forward contracts with a total notional amount of 10 million Australian dollars which mature throughout 2019, forward contracts with notional amounts totaling 31 million Canadian dollars which mature throughout 2019, forward contracts with notional amounts totaling 30.0 million British pounds which mature throughout 2019, forward contracts with notional amounts totaling 747.5 million South African rand which mature throughout 2019 and 2020. The Company’s objectives 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 are not designated as hedges, and accordingly, all changes in the fair value of the instruments are recognized as a loss (gain) on foreign currency in the Consolidated Statements of Income. The maximum time frame for ARRIS’s derivatives is currently twenty months. 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 (in thousands): Balance Sheet Location December 31, 2018 December 31, 2017 Foreign exchange contracts — asset derivatives Other current assets $ 3,964 $ 405 Foreign exchange contracts — asset derivatives Other assets 478 — Foreign exchange contracts — liability derivatives Other accrued liabilities (405 ) (8,202 ) Foreign exchange contracts — liability derivatives Other noncurrent liabilities — (600 ) The change in the fair values of ARRIS’s derivatives not designated as hedging instruments recorded in the Consolidated Statements of Income were as follows (in thousands): Statements of Income Location 2018 2017 2016 Foreign exchange contracts (Gain) loss on foreign currency $ (15,969 ) $ 25,339 $ 5,909

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 against 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.

Segment Reporting [Abstract]
Segment Information	Note 11. 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 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 2016 and 2017 period has been restated to reflect such change. The CODM manages the Company under three segments: • Customer Premises Equipment (“CPE”) • Network & Cloud (“N&C”) — • Enterprise Networks (“Enterprise”) — These operating segments are 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. The “Corporate and Unallocated Costs” category of expenses include corporate sales and marketing (excluding Enterprise segment), home office general and administrative expenses. Marketing and sales expenses related to the Enterprise segment are considered a direct operating expense for that segment and are not included in the “Corporate and Unallocated Costs.” These expenses are not included in the measure of segment direct contribution and as such are reported as “Corporate and Unallocated Costs” and are included in the reconciliation to income (loss) before income taxes. A measure of assets is not applicable, as segment assets are not regularly reviewed by the CODM for evaluating performance or allocating resources. The tables below present information about the Company’s reportable segments (in thousands): 2018 2017 2016 Net sales to external customers: CPE $ 3,923,894 $ 4,475,670 $ 4,747,445 N&C 2,156,577 2,094,113 2,111,708 Enterprise 675,352 45,749 — Other (13,183 ) (1,140 ) (30,035 ) Total 6,742,640 6,614,392 6,829,118 Direct contribution: CPE 270,510 456,562 647,117 N&C 848,938 724,597 595,866 Enterprise 64,667 1,389 — Segment total 1,184,115 1,182,548 1,242,983 Corporate and unallocated costs (576,347 ) (530,772 ) (581,991 ) Amortization of intangible assets (383,561 ) (375,407 ) (397,464 ) Impairment of goodwill and intangible assets (3,400 ) (55,000 ) (2,200 ) Integration, acquisition, restructuring and other costs, net (41,922 ) (98,357 ) (150,611 ) Operating income 178,885 123,012 110,717 Interest expense 95,086 87,088 79,817 Loss on investments 308 11,066 21,194 Loss (gain) on foreign currency 3,834 9,757 (13,982 ) Interest income (8,341 ) (7,975 ) (4,395 ) Other expense (income), net 5,056 1,873 3,991 Income before income taxes $ 82,942 $ 21,203 $ 24,092 For the years ended December 31, 2018, 2017 and 2016, the composition of our corporate and unallocated costs that are reflected in the Consolidated Statements of Income were as follows (in thousands): 2018 2017 2016 Corporate and unallocated costs: Cost of sales $ 85,838 $ 56,952 $ 118,001 Selling, general and administrative expenses 385,273 374,933 367,225 Research and development expenses 105,236 98,887 96,765 Total $ 576,347 $ 530,772 $ 581,991 The following table summarizes the Company’s net intangible assets and goodwill by reportable segment as of December 31, 2018 and 2017 (in thousands): CPE N&C Enterprise Total December 31, 2018 Goodwill $ 1,380,817 $ 570,852 $ 288,973 $ 2,240,642 Intangible assets, net 587,728 398,856 417,075 1,403,659 December 31, 2017 Goodwill $ 1,386,680 $ 573,798 $ 318,034 $ 2,278,512 Intangible assets, net 807,314 501,998 462,050 1,771,362 The following table summarizes the Company’s revenues by products and services as of December 31, 2018, 2017 and 2016 (in thousands): 2018 2017 2016 CPE: Broadband CPE $ 1,643,152 $ 1,808,600 $ 1,683,491 Video CPE 2,280,742 2,667,070 3,063,954 Sub-total 3,923,894 4,475,670 4,747,445 Network & Cloud: Networks 1,850,416 1,747,936 1,789,097 Software and services 306,161 346,177 322,611 Sub-total 2,156,577 2,094,113 2,111,708 Enterprise Networks: Enterprise Networks 675,352 45,749 — Other: Other (1) (13,183 ) (1,140 ) (30,035 ) Total net sales $ 6,742,640 $ 6,614,392 $ 6,829,118 (1) Includes adjustments related to acquisition accounting impacts on deferred revenues in 2018 and 2017 and reduction in revenue related to warrants in 2016.

Lease Financing Obligation	Note 15. Lease Financing Obligation Sale-leaseback of San Diego Office Complex: In 2015, the Company sold its San Diego office complex consisting of land and buildings with a net book value of $71.0 million, for total consideration of $85.5 million. The Company concurrently entered into a leaseback arrangement for two buildings on the San Diego campus (“Building 1” and “Building 2”) with an initial leaseback term of ten years for Building 1 and a maximum term of one year for Building 2. The Company determined that the sale-leaseback of Building 1 did not qualify for sale-leaseback accounting due to continuing involvement that will exist for the 10-year lease term. Accordingly, the carrying amount of Building 1 will remain on the Company’s balance sheet and will be depreciated over its remaining useful life with the proceeds reflected as a financing obligation. The Company concluded that Building 2 qualified for sale-leaseback accounting with the subsequent leaseback classified as an operating lease. At December 31, 2018, the minimum lease payments required on the financing obligation were as follows (in thousands): 2019 $ 4,388 2020 4,520 2021 4,655 2022 4,795 2023 4,939 Thereafter through 2025 6,368 Total minimum lease payments $ 29,665

The Fourth Amendment provided for a new Term B 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 remain 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. In connection with the Amendments in 2017, the Company paid and capitalized approximately $1.4 million of financing fees and $4.5 million of original issuance discount. In addition, the Company expensed approximately $4.5 million of debt issuance costs and wrote off approximately $1.3 million of existing debt issuance costs associated with certain lenders who were not party to the credit facility, which were included as interest expense in the Consolidated Statements of Income for the year ended December 31, 2017. Interest rates on borrowings under the senior secured credit facilities are set forth in the table below. Rate As of December 31, 2018 Term Loan A LIBOR + 1.75 % 4.27% Term Loan A-1 LIBOR + 1.75 % 4.27% Term Loan B-3 LIBOR + 2.25 % 4.77% 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 Loan A, Term Loan A-1, Term Loan B-3 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 of 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 December 31, 2018, ARRIS was in compliance with all covenants under the Credit Agreement. During 2018 and 2017, the Company made mandatory payments of approximately $87.5 million and $91.7 million, respectively, related to the senior secured credit facilities.

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 computations for the periods indicated (in thousands, except per share data): For the Years Ended December 31, 2018 2017 2016 Basic: Net income attributable to ARRIS International plc $ 113,740 $ 92,027 $ 18,100 Weighted average shares outstanding 180,147 187,133 190,701 Basic earnings per share $ 0.63 $ 0.49 $ 0.09 Diluted: Net income attributable to ARRIS International plc $ 113,740 $ 92,027 $ 18,100 Weighted average shares outstanding 180,147 187,133 190,701 Net effect of dilutive shares 1,894 2,483 1,484 Total 182,041 189,616 192,185 Diluted earnings per share $ 0.62 $ 0.49 $ 0.09 Potential dilutive shares include unvested restricted and performance awards and warrants. For the year ended December 31, 2018, 2017 and 2016, approximately 1.5 million, 1.1 million and 0.9 million of the equity-based awards, respectively, were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive. 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 twelve months ended December 31, 2018, the Company issued 2.7 million shares of its ordinary shares related to the vesting of restricted stock units, as compared to 2.6 million shares for the twelve months ended December 31, 2017. Warrants have a dilutive effect in those periods in which the average market price of the shares exceeds the current effective exercise price (under the treasury stock method) and are not subject to performance conditions. There was no incremental vesting in the 2018 and 2017. During the fourth quarter of 2016, approximately 2.2 million warrants vested based on the amount of purchases of products and services by the customer from the Company. The dilutive effect of these vested shares was immaterial. The Company has not paid cash dividends on its stock 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 contains restrictions on the Company’s ability to pay dividends on its ordinary shares.

Warrants	Note 18. Warrants During 2016, the Company entered into two separate Warrant and Registration Rights Agreements (the “Warrants”) with certain customers pursuant to which those customers may purchase up to 14.0 million of ARRIS’s ordinary shares, (subject to adjustment in accordance with the terms of the Warrants, the “Shares”). The Warrants will vest in tranches based on the amount of purchases of products and services by the customer from the Company. At December 31, 2018 and December 31, 2017, approximately 2.2 million Warrants were vested and outstanding, with a weighted average exercise price of $24.64, which vested based on the amount of purchases of products and services by the customers from the Company in 2016. For the year ended December 31, 2018 and 2017, there were no adjustments related to the Warrants. For the year ended December 31, 2016, ARRIS recorded $30.2 million as a reduction to net sales in connection with Warrants.

Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017, a new alternative U.S. tax on certain Base Erosion Anti-Avoidance (BEAT) payments from a U.S. company to any foreign related party, a new U.S. tax on certain off-shore earnings referred to as Global Intangible Low-Taxed Income (GILTI), additional limitations on certain executive compensation, and limitations on interest deductions. 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 was required to recognize the effect of the tax law changes in the period of enactment, such as determining the transition tax, remeasuring its U.S. deferred tax assets and liabilities as well as reassessing the realizability of its deferred tax assets. Due to the timing of the enactment and the complexity in applying the provisions of the Act, the Company made reasonable estimates of the impact of the Act in its December 31, 2017 year end income tax provision in accordance with Staff Accounting Bulletin No. 118, its understanding of the Act and other relevant guidance available. As the Company collected and prepared necessary data, and interpreted the additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service, and other standard-setting bodies, we made certain adjustments, over the course of the year ended December 31, 2018, to the provisional amounts including refinement to deferred taxes and the one-time transition tax. The accounting for the effects of the Act has been completed as of December 31, 2018. The Act required us to pay U.S. income taxes on accumulated foreign subsidiary earnings not previously subject to U.S. income tax. The provisional amount for one-time transition tax liability was not material as of December 31, 2017. During 2018, this amount was finalized and as of December 31, 2018 our one-time transition tax liability and income tax expense is zero. Due to the change in the U.S. federal statutory rate from the Act, the Company remeasured the deferred taxes at December 31, 2017 to reflect the reduced rate. The Company recognized a provisional income tax benefit amount of ($22.3) million related to this remeasurement of certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future. Due to the finalization of the effects of the Tax Act the company recorded $1.5 million of income tax expense in the period ended December 31, 2018 related to the remeasurement of these deferred tax amounts. Deferred income taxes reflect the net tax effects of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of ARRIS’s net deferred income tax assets (liabilities) were as follows (in thousands): December 31, 2018 2017 Deferred income tax assets Inventory costs $ 21,471 $ 29,453 Property, plant and equipment 12,333 — Accrued employee benefits 22,595 34,472 Accrued operating expenses 42,290 24,904 Reserves 13,144 16,434 Investments — 8,796 Loss carryforwards 68,518 91,832 Research and development and other credits 181,851 164,841 Capitalized research and development 97,975 83,224 Other 26,157 17,379 Total deferred income tax assets 486,334 471,335 Deferred income tax liabilities: Property, plant and equipment — (571 ) Investments (1,970 ) — Other liabilities (3,026 ) (7,190 ) Goodwill and intangible assets (262,660 ) (325,283 ) Total deferred income tax liabilities (267,656 ) (333,044 ) Net deferred income tax assets 218,678 138,291 Valuation allowance (90,057 ) (91,743 ) Net deferred income tax assets $ 128,621 $ 46,548 Significant attributes of ARRIS’s deferred tax assets related to loss carryforwards and tax credits were as follows: (in thousands): 2018 2017 Expiration Net operating loss carryforwards (“NOL”): U.S. federal (1) $ 7,117 $ 27,405 2019 - 2029 Georgia 15,211 15,948 2019 - 2038 Pennsylvania 17,400 17,687 2019 - 2038 Other U.S. states 10,944 12,236 2019 - 2038 Non-U.S. 17,846 18,556 Varies (2) Total tax effected loss carryforward $ 68,518 $ 91,832 Tax credit carryforwards: U.S. federal R&D $ 119,257 $ 103,581 2019 - 2038 Other U.S. federal — 5,742 California R&D 40,335 34,208 Indefinite Other U.S. states R&D 22,259 21,310 2019 - 2038 Total credit carryforward $ 181,851 $ 164,841 (1) Gross of tax effect U.S. Federal operating loss carryforwards are $33.9 million for the year ended December 31, 2018 and $130.5 million for the year ended December 31, 2017. (2) $2.9 million of this amount is located in Mexico and Israel, both of which have an expiration of ten years, Canadian NOLs expire within 16 years and all other foreign NOLs have an indefinite carryforward life. ARRIS’ ability to use U.S. federal, state, and other foreign net operating loss carryforwards to reduce future taxable income, or to use U.S. federal and state research and development tax credits and other carryforwards to reduce future income tax liabilities, is subject to the ability to generate sufficient taxable income of an appropriate characterization in the appropriate taxing jurisdictions. In some instances, the utilization is also subject to restrictions attributable to change of ownership during prior tax years. as defined by appropriate law in the relevant taxing jurisdiction. These limitations, as noted above, prevent the Company from utilizing certain deferred tax assets and were considered in establishing our valuation allowances. Components of ARRIS’s valuation allowance were as follows (in thousands): 2018 2017 U.S. federal R&D $ (5,239 ) $ (8,578 ) Other U.S. federal (1,585 ) (4,241 ) Georgia NOL (14,478 ) (15,008 ) Pennsylvania NOL (9,887 ) (10,068 ) Other state NOL (9,111 ) (8,988 ) California R&D (25,994 ) (18,773 ) Other state R&D (15,635 ) (15,606 ) Non-U.S. NOL (8,128 ) (10,481 ) Ending balance $ (90,057 ) $ (91,743 ) A roll-forward analysis of our deferred tax asset valuation allowances is as follows (in thousands): For the Period ended December 31, 2018 2017 2016 Beginning balance $ 91,743 $ 57,772 $ 87,788 Additions 13,082 52,680 17,973 Reductions (14,768 ) (18,709 ) (47,989 ) Ending balance $ 90,057 $ 91,743 $ 57,772 During 2018 the Company changed its indefinite reinvestment assertion and therefore recorded deferred income taxes on a portion of the unremitted earnings of certain subsidiaries. As of December 31, 2018, no deferred taxes have been provided for the portion of the unremitted earnings of certain of the Company’s subsidiaries. The earnings amount to approximately $20.9 million which if distributed may result in additional taxes. Determination of the amount of additional taxes is not practicable because of the complexities associated with this hypothetical calculation. The remaining unremitted earnings of foreign subsidiaries for which the Company does not assert indefinite reinvestment have a deferred tax liability recorded of $8.7 million. Tabular Reconciliation of Unrecognized Tax Benefits (in thousands) For the Period ended December 31, 2018 2017 2016 Beginning balance $ 174,225 $ 128,053 $ 49,919 Gross increases — tax positions in prior period 7,055 6,783 8,068 Gross decreases — tax positions in prior period (6,368 ) (21,409 ) (5,700 ) Gross increases — current-period tax positions 24,767 24,551 27,774 Changes from acquired businesses (34,199 ) 39,420 60,796 Changes related to foreign currency translation and remeasurement (2,284 ) 1,545 (1,087 ) Decreases relating to settlements with taxing authorities and other (202 ) (686 ) (3,933 ) Decreases due to lapse of statute of limitations (13,122 ) (4,032 ) (7,784 ) Ending balance $ 149,872 $ 174,225 $ 128,053 The Company and its subsidiaries file income tax returns in the U.S. and U.K. jurisdictions, and various state and other foreign jurisdictions. As of December 31, 2018, the Company and its subsidiaries were under income tax audit in various jurisdictions including the United Kingdom (2013 onwards), the United States (2015 onwards), Hong Kong (2014 onwards), Brazil (2010, 2012 and 2014 onwards) and various states and other foreign countries. ARRIS does not anticipate audit adjustments in excess of its current accrual for uncertain tax positions. Liabilities related to uncertain tax positions inclusive of interest and penalties were $153.6 million and $178.2 million at December 31, 2018 and 2017, respectively. These liabilities at December 31, 2018 and 2017 were reduced by $34.6 million and $29.6 million, respectively, for offsetting benefits from the corresponding effects of potential transfer pricing adjustments, state income taxes and other unrecognized tax benefits. These offsetting benefits are recorded in other non-current assets and noncurrent deferred income taxes. The net result of $119.0 million and $148.6 million at December 31, 2018 and 2017, respectively, if recognized and released, would favorably affect tax expense. Included in the net result of $119.0 million as of December 31, 2018, is $5.2 million of net acquired uncertain tax positions related to Ruckus Networks. This amount is fully indemnified and offset by a corresponding indemnification asset recorded in other non-current assets. The Company reported approximately $3.7 million and $4.0 million, respectively, of interest and penalty accrual related to the anticipated payment of these potential tax liabilities as of December 31, 2018 and 2017. The Company classifies interest and penalties recognized on the liability for uncertain tax positions as income tax expense. Based on information currently available, the Company anticipates that over the next twelve-month period, statutes of limitations may close and audit settlements will occur relating to existing unrecognized tax benefits of approximately $12.1 million primarily arising from U.K. and U.S. federal and state tax related items.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Note 20. Stock-Based Compensation ARRIS grants stock awards under its 2016 Stock Incentive Plan (“SIP”). Upon approval of the 2016 SIP, all shares available for grant under the Company’s other existing stock incentive plans were no longer available. The Board of Directors approved the SIP and the prior plans to facilitate the retention and continued motivation of key employees, consultants and directors, and to align more closely their interests with those of the Company and its stockholders. Awards under the SIP may be in the form of stock options, stock grants, stock units, restricted stock, stock appreciation rights, performance shares and units, and dividend equivalent rights. A total of 31,215,000 shares of the Company’s shares may be issued pursuant to the SIP. The SIP has been designed to allow for flexibility in the form of awards; however, awards denominated in ordinary shares other than stock options and stock appreciation rights will be counted against the SIP limit as 1.87 shares for every one share covered by such an award. The vesting requirements for issuance under the SIP may vary; however, awards generally are required to have a minimum three-year vesting period or term. Restricted Stock (Non-Performance) Units ARRIS grants restricted stock units to certain employees and its non-employee directors. The Company records a fixed compensation expense equal to the fair market value of the underlying shares of restricted stock unit granted on a straight-line basis over the requisite services period for the restricted shares. The Company applies an estimated forfeiture rate based upon historical rates. The fair value is the market price of the underlying ordinary shares on the date of grant. In connection with the Pace combination, ARRIS accelerated the vesting of the time-based restricted shares that otherwise were scheduled to vest in 2016 for all of its executive officers and additional acceleration of time-based restricted shares for two executives that reached retirement age eligibility that otherwise would vest in 2017, 2018 and 2019. The following table summarizes ARRIS’s unvested restricted stock unit (excluding performance-related) transactions during the year ending December 31, 2018: Ordinary Shares Weighted Average Grant Unvested at December 31, 2017 7,360,344 $ 26.18 Granted 3,930,880 26.50 Vested (2,730,727 ) 26.38 Forfeited (854,110 ) 26.79 Unvested at December 31, 2018 7,706,387 26.20 Restricted Shares Units — Subject to Comparative Market Performance ARRIS grants to certain employees restricted shares units, in which the number of shares to be issued is dependent upon the Company’s total shareholder return as compared to the shareholder return of the NASDAQ composite over a three-year period. The number of shares which could potentially be issued ranges from zero to 200% of the target award. For the awards granted in 2016, the three-year measurement period ended on December 31, 2018. The Company’s total shareholder return underperformed the NASDAQ composite over the three-year period. This resulted in zero achievement of the target award, subject to separate treatment under terms of the Acquisition Agreement with CommScope. The remaining grants outstanding that are subject to market performance are 532,385 shares at target; at 200% performance 1,064,770 would be issued. Compensation expense is recognized on a straight-line basis over the three-year measurement period and is based upon the fair market value of the shares expected to vest. The fair value of the restricted share units is estimated on the date of grant using a Monte Carlo Simulation model. Market Performance Weighted Average Grant Unvested at December 31, 2017 1,345,060 $ 22.73 Granted 596,540 27.29 Vested — — Performance adjustment (820,920 ) 22.14 Unvested at December 31, 2018 1,120,680 25.58 The total fair value of restricted share units, including both non-performance and performance-related shares, that vested during 2018, 2017 and 2016 was $73.8 million, $76.1 million and $52.3 million, respectively. Employee Stock Purchase Plan (“ESPP”) ARRIS offers an ESPP to certain employees. The plan complies with Section 423 of the U.S. Internal Revenue Code, which provides that employees will not be immediately taxed on the difference between the market price of the stock and a discounted purchase price if it meets certain requirements. Participants can request that up to 10% of their base compensation be applied toward the purchase of ARRIS ordinary shares under ARRIS’s ESPP. Purchases by any one participant are limited to $25,000 (based upon the fair market value) in any one year. The exercise price is the lower of 85% of the fair market value of the ARRIS ordinary shares on either the first day of the purchase period or the last day of the purchase period. A plan provision which allows for the more favorable of two exercise prices is commonly referred to as a “look-back” feature. Any discount offered in excess of five percent generally will be considered compensatory and appropriately is recognized as compensation expense. Additionally, any ESPP offering a look-back feature is considered compensatory. ARRIS uses the Black-Scholes option valuation model to value shares issued under the ESPP. The valuation is comprised of two components; the 15% discount of a share of ordinary shares and 85% of a six-month option held (related to the look-back feature). The weighted average assumptions used to estimate the fair value of purchase rights granted under the ESPP for 2018, 2017 and 2016, were as follows: risk-free interest rates of 2.3%, 1.2% and 0.5%, respectively; a dividend yield of 0%; volatility factor of the expected market price of ARRIS’s stock of 0.27, 0.28, and 0.37, respectively; and a weighted average expected life of 0.5 year for each. The Company recorded stock compensation expense related to the ESPP of approximately $5.7 million, $4.8 million and $4.6 million for the years ended December 31, 2018, 2017 and 2016, respectively. Unrecognized Compensation Cost As of December 31, 2018, there was approximately $161.9 million of total unrecognized compensation cost related to unvested share-based awards granted under the Company’s incentive plans. This compensation cost is expected to be recognized over a weighted-average period of 2.8 years.

Employee Benefit Plans

Retirement Benefits [Abstract]
Employee Benefit Plans	Note 21. Employee Benefit Plans The Company sponsors a qualified and a non-qualified non-contributory defined benefit pension plan that covers certain U.S. and non-U.S. employees. As of January 1, 2000, the Company froze the U.S. qualified defined pension plan benefits for its participants. These participants elected to enroll in ARRIS’s enhanced 401(k) plan. The U.S. pension plan benefit formulas generally provide for payments to retired employees based upon their length of service and compensation as defined in the plans. ARRIS’s investment policy is to fund the qualified plan as required by the Employee Retirement Income Security Act of 1974 (“ERISA”) and to the extent that such contributions are tax deductible. No minimum funding contributions was required in 2018 under the Company’s U.S. defined benefit, however the Company made a contribution of $1.8 million for the year ended December 31, 2018 to fully fund the plan termination. For the year ended December 31, 2017, the Company made a voluntary minimum funding contribution of $1.4 million to its U.S defined benefit plan. The Company also made funding contributions of $1.8 million and $1.2 million related to our non-U.S. pension plan in 2018 and 2017, respectively. The Company established a rabbi trust to fund the pension obligations of the Executive Chairman under his SERP including the benefit under the Company’s non-qualified defined benefit plan. In October 2018, the full SERP obligation was distributed to the Executive Chairman and no further obligation exists. In addition, the Company has established a rabbi trust for certain executive officers to fund the Company’s pension liability to those officers under the non-qualified plan. In late 2017, the Company commenced the process of terminating its U.S. defined benefit pension plan. The plan’s termination was approved and the Company proceeded with effecting termination, settlement of the plan obligations was completed by December 31, 2018. The plan's deferred actuarial losses of $9.2 million remaining in Accumulated other comprehensive (loss) income were recognized as expense. ARRIS also provides a non-contributory defined benefit plan which cover employees in Taiwan. Any other benefit plans outside of the U.S. are not material to ARRIS either individually or in the aggregate. As a result of restructuring activities in conjunction with the sale of the Taiwan manufacturing facility, the Company recorded a partial curtailment of the plan and recognized a deferral actuarial gain of $3.5 million as income from Accumulated other comprehensive (loss) income. The following table summarizes the change in projected benefit obligations, fair value of plan assets and the funded status of pension plan for the years ended December 31, 2018 and 2017 (in thousands): U.S. Pension Plans Non-U.S. Pension Plans 2018 2017 2018 2017 Change in Projected Benefit Obligation: Projected benefit obligation at beginning of year $ 49,220 $ 45,270 $ 38,136 $ 35,706 Service cost — — 615 664 Interest cost 1,382 1,733 393 486 Actuarial (gain) loss (2,571 ) 3,868 (139 ) 121 Benefit payments (1,766 ) (1,651 ) — — Settlements (36,585 ) — (31,544 ) (1,596 ) Foreign currency — — (1,058 ) 2,755 Projected benefit obligation at end of year $ 9,680 $ 49,220 $ 6,403 $ 38,136 Change in Plan Assets: Fair value of plan assets at beginning of year $ 19,664 $ 18,510 $ 20,324 $ 19,011 Actual return on plan assets 76 949 689 183 Company contributions 18,611 1,856 1,722 1,259 Expenses and benefits paid from plan assets (1,766 ) (1,651 ) — — Settlements (36,585 ) — (19,217 ) (1,596 ) Foreign currency — — (564 ) 1,467 Fair value of plan assets at end of year (1) $ — $ 19,664 $ 2,954 $ 20,324 Funded Status: Funded status of plan $ (9,680 ) $ (29,557 ) $ (3,449 ) $ (17,812 ) Unrecognized actuarial loss (gain) 1,334 13,981 (592 ) (1,857 ) Net amount recognized $ (8,346 ) $ (15,576 ) $ (4,041 ) $ (19,669 ) (1) In addition to the U.S. pension plan assets, ARRIS has established two rabbi trusts to further fund the pension obligations of the Executive Chairman and certain executive officers. The obligation for the Executive Chairman was distributed in the fourth quarter of 2018. The balance in the trusts as of December 31, 2018 and 2017 are $9.7 million and $25.4 million, respectively, and are included in Investments on the Consolidated Balance Sheets.

Gains/losses are amortized on a straight-line basis over the average future service of members expected to receive benefits Estimated amounts to be amortized from accumulated other comprehensive (loss) income into net periodic benefit costs in the year ending December 31, 2019 based on December 31, 2018 plan measurements are $0.1 million, consisting primarily of amortization of the net actuarial loss in the U.S. pension plans. The assumptions used to determine the benefit obligations as of December 31, 2018, 2017 and 2016 are as set forth below (in percentage): U.S. Pension Plans Non-U.S. Pension Plans 2018 2017 2016 2018 2017 2016 Weighted-average assumptions used to determine benefit obligations: Discount rate 4.05 % 3.45 % 3.90 % 1.00 % 1.10 % 1.30 % Rate of compensation increase N/A N/A N/A N/A N/A N/A Weighted-average assumptions used to determine net periodic benefit costs: Discount rate 3.50 % 3.90 % 4.15 % 1.10 % 1.30 % 1.70 % Expected long-term rate of return on plan assets N/A 5.00 % 6.00 % 1.40 % 1.40 % 1.60 % Rate of compensation increase (1) N/A N/A N/A 4.00 % 3.00 % 3.00 % (1) Represent an average rate for the non-U.S. pension plans. Rate of compensation increase is 4.00% for indirect labor for 2018, 2017 and 2016, and 2.00% for direct labor for 2017 and 2016. The expected long-term rate of return on assets is derived using the building block approach which includes assumptions for the long-term inflation rate, real return, and equity risk premiums. No minimum funding contributions are required for 2019 for the U.S. Pension plan, however the Company may make a voluntary contribution. The Company estimates it will make funding contributions $0.3 million in 2019 for the non-U.S. plan. As of December 31, 2018, the expected benefit payments related to the Company’s defined benefit pension plans during the next ten years are as follows (in thousands): U.S. Pension Plans Non-U.S. Pension Plans 2019 $ 520 $ 158 2020 520 154 2021 530 553 2022 530 246 2023 640 309 2024— 2028 3,320 2,309 The investment strategies of the plans place a high priority on benefit security. The plans invest conservatively so as not to expose assets to depreciation in adverse markets. The plans’ strategy also places a high priority on earning a rate of return greater than the annual inflation rate along with maintaining average market results. The plan has targeted asset diversification across different asset classes and markets to take advantage of economic environments and to also act as a risk minimizer by dampening the portfolio’s volatility.

Investments in mutual funds are valued at the net asset value per share multiplied by the number of shares held. (3) Fixed income securities consist of bonds securities in mutual funds and are valued at the net asset value per share multiplied by the number of shares held. Other Benefit Plans ARRIS has established defined contribution plans pursuant to the Internal Revenue Code Section 401(k) that cover all eligible U.S. employees. ARRIS contributes to these plans based upon the dollar amount of each participant’s contribution. ARRIS made matching contributions to these plans of approximately $22.8 million, $16.5 million and $16.4 million in 2018, 2017 and 2016, respectively. The Company has a deferred compensation plan that does not qualify under Section 401(k) of the Internal Revenue Code and is available to key executives of the Company and certain other employees. Employee compensation deferrals and matching contributions are held in a rabbi trust. The total of net employee deferrals and matching contributions, which is reflected in other long-term liabilities, was $5.4 million and $5.7 million at December 31, 2018 and 2017, respectively. Total expenses included in continuing operations for the matching contributions were approximately $0.1 million and $0.3 million in 2018 and 2017, respectively. The Company previously offered a deferred compensation arrangement, which allowed certain employees to defer a portion of their earnings and defer the related income taxes. As of December 31, 2004, the plan was frozen and no further contributions are allowed. The deferred earnings are invested in a rabbi trust. The total of net employee deferral and matching contributions, which is reflected in other long-term liabilities, was $2.0 million and $3.1 million at December 31, 2018 and 2017, respectively. The Company also has a deferred retirement salary plan, which was limited to certain current or former officers. The present value of the estimated future retirement benefit payments is being accrued over the estimated service period from the date of signed agreements with the employees. The accrued balance of this plan, the majority of which is included in other long-term liabilities, were $1.9 million and $1.5 million at December 31, 2018 and 2017, respectively. Total expenses (income) included in continuing operations for the deferred retirement salary plan were approximately $0.4 million and $0.2 million for 2018 and 2017, respectively.

Equity [Abstract]
Repurchases of Stock	Note 23. Repurchases of Stock Upon completing the Pace combination, 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 2018, the Company repurchased 13.9 million of its ordinary shares for $353.1 million at an average stock price of $25.38. The remaining authorized amount for share repurchases was $546.9 million as of December 31, 2018. During 2017, ARRIS repurchased 7.5 million shares of its ordinary shares at an average price of $26.12 per share, for an aggregate consideration of approximately $197.0 million. Unless terminated earlier by a Board resolution, this new plan 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 because we are 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, we obtained approval to purchase our own shares. This authority to repurchase shares terminates in January 2021, unless otherwise reapproved by our shareholders. Under the terms of the Acquisition Agreement, the Company has agreed not to purchase additional shares prior to the closing of the Acquisition without the consent of CommScope.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 24. Commitments and Contingencies General Matters ARRIS leases office, distribution, and warehouse facilities as well as equipment under long-term leases expiring at various dates through 2027. Included in these operating leases are certain amounts related to restructuring activities; these lease payments and related sublease income are included in restructuring accruals on the Consolidated Balance Sheets. Future minimum operating lease payments under non-cancelable leases at December 31, 2018 were as follows (in thousands): Operating Leases 2019 $ 34,495 2020 29,824 2021 27,092 2022 22,207 2023 18,623 Thereafter 27,605 Less sublease income (3,637 ) Total minimum lease payments $ 156,209 Total rental expense for all operating leases amounted to approximately $32.1 million, $26.4 million and $34.0 million for the years ended December 31, 2018, 2017 and 2016, respectively. Additionally, the Company had contractual obligations of approximately $595.4 million under agreements with non-cancelable terms to purchase goods or services over the next year. All contractual obligations outstanding at the end of prior years were satisfied within a 12-month period, and the obligations outstanding as of December 31, 2018 are expected to be satisfied by the end of 2019. 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 allegations 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, the Company is currently unable to reasonably estimate the possible loss or range of possible loss for any of the matters identified in Part I, Item 3 “Legal Proceedings”. The results in litigation are unpredictable and an adverse resolution of one or more of such matters not included in the estimate provided, or if losses are higher than what is currently estimated, it could have a material adverse effect on our business, financial position, results of operations or cash flows. In addition, the Company is a defendant in various litigation matters generally arising out of the normal course of business. (See Part I, Item 3 “Legal Proceedings” for additional details).

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Consolidation	(a) Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries and consolidated venture in which the Company owns more than 50% of the outstanding voting shares of the entity. Intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP), and our reporting currency is the United States Dollar (USD).
Use of Estimates	(b) Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Reclassifications	(c) Reclassifications Certain prior year amounts in the financial statements and notes have been reclassified to conform to the fiscal year 2018 presentation.
Cash, Cash Equivalents, and Investments	(d) Cash, Cash Equivalents, and Investments Cash and cash equivalents ARRIS’s cash and excess cash are primarily held in demand deposit accounts and money market accounts. The Company classifies all investments that are readily convertible to known amounts of cash and have stated maturities of three months or less from the date of purchase as cash equivalents and those with stated maturities of greater than three months as marketable securities. Marketable securities The Company determines the appropriate classification of our investments in marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its marketable debt securities as available-for-sale. These securities are carried at fair value, and the unrealized gains and losses, net of taxes, are reported as a component of stockholders’ equity, except for unrealized losses determined to be other-than-temporary, which are recorded within loss on investments in the Consolidated Statements of Income. The Company determines any realized gains or losses on the sale of marketable debt securities on a specific identification method and records such gains and losses as a gain or loss on investment in the Consolidated Statements of Income. Non-marketable investments The Company accounts for non-marketable equity investments through which the Company exercises significant influence but does not have control over the investee under the equity method. Beginning on January 1, 2018, non-marketable equity securities not accounted for under the equity method are either carried at fair value or under the measurement alternative upon the adoption of accounting standard Recognition and Measurement of Financial Assets and Financial Liabilities Impairment of investments The Company periodically reviews its debt and equity investments for impairment. For debt securities the Company considers the duration, severity and the reason for the decline in security value; whether it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or if the amortized cost basis cannot be recovered as a result of credit losses. If any impairment is considered other-than-temporary, the Company will write down the security to its fair value and record the corresponding charge as a loss on investments. For equity securities the Company considers impairment indicators such as negative changes in industry and market conditions, financial performance, business prospects, and other relevant events and factors. If indicators exist and the fair value of the security is below the carrying amount, the Company writes down the security to fair value.
Accounts Receivable and Allowance for Doubtful Accounts and Sales Returns	(e) Accounts Receivable and Allowance for Doubtful Accounts and Sales Returns Accounts receivable are stated at amounts owed by the customers, net of allowance for doubtful accounts, sales returns and allowances. ARRIS establishes a reserve for doubtful accounts based upon the historical experience and leading market indicators in collecting accounts receivable. A majority of the accounts receivable are from a few large cable system operators and telecommunication companies, either with investment rated debt outstanding or with substantial financial resources and have favorable payment histories. If ARRIS was to have a collection problem with one of its major customers, it is possible the reserve will not be sufficient. ARRIS calculates the reserve for uncollectible accounts using a model that considers customer payment history, recent customer press releases, bankruptcy filings, if any, Dun & Bradstreet reports, and financial statement reviews. The calculation is reviewed by management to assess whether there needs to be an adjustment to the reserve for uncollectible accounts. The reserve is established through a charge to the provision and represents amounts of current and past due customer receivable balances of which management deems a loss to be both probable and estimable. Accounts receivable are charged to the allowance when determined to be no longer collectible. ARRIS also establishes a reserve for sales returns and allowances. The reserve is an estimate of the impact of potential returns based upon historic trends. The following table represents a summary of the changes in the reserve for allowance for doubtful accounts, and sales returns and allowances for fiscal 2018, 2017 and 2016 (in thousands): 2018 2017 2016 Balance at beginning of fiscal year $ 10,230 $ 15,253 $ 9,975 (Credit) charges to expenses (462 ) (566 ) 1,386 (Write-offs) recoveries, net (2,326 ) (4,457 ) 3,892 Balance at end of fiscal year $ 7,442 $ 10,230 $ 15,253
Inventories	(f) Inventories Inventories are stated at the lower of cost or net realizable value. Inventory cost is determined on a first-in, first-out basis. The cost of work-in-process and finished goods is comprised of material, labor, and overhead.
Revenue recognition	(g) Revenue recognition On January 1, 2018, the Company adopted the new accounting standard Revenue from Contracts with Customers using the modified retrospective transition method. The Company has elected to apply the new standard to contracts that were considered “open” as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new accounting standard, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under previous guidance. ARRIS generates revenue from of 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 the amount of consideration expected to be received. 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 performance obligations typically include proprietary operating system software, which isn’t considered separately identifiable. Therefore, ARRIS’s equipment and their related software are considered one 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 are recognized over time because the customer simultaneously receives and consumes the benefits of the service as the services are performed. · 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 – 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 270 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 sales incentive programs, the Company can reasonably estimate its 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.
Shipping and Handling Fees	(h) Shipping and Handling Fees Shipping and handling costs for the years ended December 31, 2018, 2017, and 2016 were approximately $13.2 million, $12.6 million and $4.3 million, respectively, and are classified in cost of sales.
Taxes Collected from Customers and Remitted to Governmental Authorities	(i) Taxes Collected from Customers and Remitted to Governmental Authorities Taxes assessed by a government authority that are both imposed on and concurrent with specific revenue transactions between us and our customers are presented on a net basis in our Consolidated Statements of Income.
Depreciation of Property, Plant and Equipment	(j) Depreciation of Property, Plant and Equipment The Company provides for depreciation of property, plant and equipment on the straight-line basis over estimated useful lives of 10 to 40 years for buildings and improvements, 2 to 10 years for machinery and equipment, and the shorter of the term of the lease or useful life for leasehold improvements. Included in depreciation expense is the amortization of landlord funded tenant improvements which amounted to $14.0 million in 2018, $12.1 million in 2017 and $6.6 million in 2016. Depreciation expense, including amortization of capital leases, for the years ended December 31, 2018, 2017, and 2016 was approximately $83.7 million, $88.2 million, and $90.6 million, respectively. See Note 13 Property, Plant and Equipment
Goodwill and Purchased Intangible Assets	(k) Goodwill and Purchased Intangible Assets Goodwill is tested for impairment annually as of October 1st, or when an indicator of impairment exists. As of October 1, 2017, we early adopted Accounting Standards Update (“ASU”) 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 eliminated Step 2 of the goodwill impairment test in which an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities. The standard does not change the guidance on completing Step 1 of the goodwill impairment test. In accordance with the new standard, we compare the fair value of our reporting units with the carrying amount, including goodwill. The Company recognizes an impairment charge for the amount by which the carrying amount exceeds a reporting unit’s fair value, as applicable. Purchased intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. Useful lives of identifiable intangible assets are determined after considering the specific facts and circumstances related to each intangible asset. Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their useful lives, generally ranging from 1 to 13 years. Certain intangible assets are being amortized using an accelerated method, as an accelerated method best approximates the distribution of cash flows generated by the intangible assets. See “Long-Lived Assets” for the Company’s policy regarding impairment testing of purchased intangible assets with finite lives. Purchased intangible assets with indefinite lives are assessed for potential impairment annually or when events or circumstances indicate that their carrying amounts might be impaired. See Note 6 Goodwill and Other Intangible Assets Long-Lived Assets Long-lived assets, including property, plant and equipment and intangible assets with finite lives, that are held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability of long-lived assets is based on an estimate of the undiscounted future cash flows resulting from the use of the asset and its eventual disposition. To test for recovery, the Company groups assets (an “asset group”) in a manner that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. If the sum of the expected future cash flows (undiscounted and pre-tax based upon policy decision) is less than the carrying amount, the Company recognizes an impairment loss. The impairment loss recognized is the amount by which the carrying amount of the asset or asset group exceeds the fair value. A variety of methodologies are used to determine the fair value of these assets, including discounted cash flow models, which are consistent with the assumptions the Company believes hypothetical marketplace participants would use. Measurement of an impairment loss for long-lived assets that management expects to hold and use is based on the difference between the fair value of the asset and its carrying value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
Advertising and Sales Promotion	(l) Advertising and Sales Promotion Advertising and sales promotion costs are expensed as incurred. Advertising and sales promotion expense was approximately $23.5 million, $17.5 million, and $19.6 million for the years ended December 31, 2018, 2017 and 2016, respectively.
Research and Development	(m) Research and Development Research and development (“R&D”) costs are expensed as incurred. The expenditures include compensation costs, materials, other direct expenses, and an allocation of information technology, telecommunications, and facilities costs.
Warranty	(n) Warranty ARRIS provides warranties of various lengths to customers based on the specific product and the terms of individual agreements. For further discussion, see Note 10 Guarantees
Income Taxes	(o) Income Taxes ARRIS uses the liability method of accounting for income taxes, which requires recognition of temporary differences between financial statement and income tax bases of assets and liabilities, measured by enacted tax rates. If necessary, the measurement of deferred tax assets is reduced by a valuation allowance to an amount that is more likely than not to be realized based on available evidence. ARRIS reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company elects to account for Global Intangible Low-Taxed Income (“GILTI”) in the period the tax is incurred. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in Income tax (benefit) expense in the Consolidated Statements of Income. See Note 19 Income Taxes
Foreign Currency	(p) Foreign Currency A significant portion of the Company’s products are manufactured or assembled in Brazil, China, Mexico and Taiwan, and we have research and development centers in Canada, China, France, India, Ireland, Israel, Singapore, Sweden, Taiwan and United Kingdom. Sales into international markets have been and are expected in the future to be an important part of the Company’s business. These foreign operations are subject to the usual risks inherent in conducting business abroad, including risks with respect to currency exchange rates, economic and political destabilization, restrictive actions and taxation by foreign governments, nationalization, the laws and policies of the United States affecting trade, foreign investment and loans, and foreign tax laws. The financial position and results of operations of certain of the Company’s international subsidiaries are measured using the local currency as the functional currency. Revenues and expenses of these subsidiaries are translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities of these subsidiaries are translated at the exchange rates as of the balance sheet date. Translation gains and losses are recorded in Accumulated other comprehensive (loss) income. ARRIS has certain international customers who are billed in their local currency and certain international operations 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. The Company enters into forward or currency option contracts based on a percentage of expected foreign currency exposures. The percentage can vary, based on the predictability of the exposures denominated in the foreign currency. See Note 9 Derivative Instruments and Hedging Activities
Stock-Based Compensation	(q) Stock-Based Compensation See Note 20 Stock-Based Compensation
Concentrations of Credit Risk	(r) Concentrations of Credit Risk Financial instruments that potentially subject ARRIS to concentrations of credit risk consist principally of cash, cash equivalents and short-term investments, accounts receivable and derivatives. ARRIS places its temporary cash investments with high credit quality financial institutions. Concentrations with respect to accounts receivable occur as the Company sells primarily to large, well- established companies, including companies outside of the United States. The Company’s credit policy generally does not require collateral from its customers. ARRIS closely monitors extensions of credit to other parties and, where necessary, utilizes common financial instruments to mitigate risk or requires cash on delivery terms. Overall financial strategies and the effect of using a hedge are reviewed periodically. As of December 31, 2018, two customers represented 13% and 12% of total accounts receivable. As of December 31, 2017, two customers represented 19% and 14% of total accounts receivable.
Fair Value	(s) Fair Value 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. In order 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. Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments: • Cash, cash equivalents, and short-term investments: The carrying amounts reported in the Consolidated Balance Sheets for cash, cash equivalents, and short-term investments approximate their fair values. • Accounts receivable and accounts payable: The carrying amounts reported in the balance sheet for accounts receivable and accounts payable approximate their fair values. • Marketable securities: The fair values for available-for-sale equity securities are based on quoted market prices or observable prices based on inputs not in active markets but corroborated by market data. • Non-marketable securities: Non-marketable equity securities are subject to a periodic impairment review; however, there are no open-market valuations, and the impairment analysis requires significant judgment. This analysis includes assessment of the investee’s financial condition, the business outlook for its products and technology, its projected results and cash flow, recent rounds of financing, and the likelihood of obtaining subsequent rounds of financing. • Senior secured credit facilities: Comprised of term loans and a revolving credit facility of which the outstanding principal amount approximates fair value because of interest-bearing rates that are adjusted periodically, analysis of recent market conditions, prevailing interest rates and other Company specific factors. • Derivative instruments: The carrying amounts reported in the balance sheet for derivative financial instruments reflect their estimated fair values, as the valuation inputs are based on quoted prices and market observable data of similar instruments.
Computer Software	(t) Computer Software Internal-use software The Company capitalizes costs associated with internally developed and/or purchased software systems for internal use that have reached the application development stage and meet recoverability tests. Capitalized costs include external direct costs of materials and services utilized in developing or obtaining internal-use software and payroll and payroll-related expenses for employees who are directly associated with and devote time to the internal-use software project. Capitalization of such costs begins when the preliminary project stage is complete and ceases no later than the point at which the project is substantially complete and ready for its intended purpose. These capitalized costs are amortized on a straight-line basis over periods of two to seven years, beginning when the asset is ready for its intended use. Capitalized costs are included in property, plant, and equipment on the Consolidated Balance Sheets. External-use software Research and development costs are charged to expense as incurred. ARRIS generally has not capitalized any such development costs because the costs incurred between the attainment of technological feasibility for the related software product through the date when the product is available for general release to customers has been insignificant. Cloud Computing Arrangements Implementation costs incurred in a cloud computing arrangement that is a service contract are capitalized similar to implementation costs incurred to develop or obtain internal-use software. Amortization is computed over the term of the hosting arrangement. As of December 31, 2018, implementation costs of $11.9 million associated with cloud computing arrangements has been capitalized and is included in Other Assets in the Consolidated Balance Sheets.
Comprehensive (Loss) Income	(u) Comprehensive (Loss) Income The components of comprehensive (loss) income include net income (loss), unrealized gains (losses) on available-for-sale debt securities, unrealized gains (losses) on certain derivative instruments, change in pension liabilities, net of tax, if applicable and foreign currency translation adjustments.
Warrants	(v) Warrants The Company has outstanding warrants with certain customers to purchase ARRIS’s ordinary shares. Vesting of the warrants is subject to certain purchase volume commitments by the customers. Under applicable accounting guidance, if the vesting of a tranche of the warrants is probable, the Company is required to mark-to-market the fair value of the warrant until it vests, and any increase in the fair value is treated as a reduction in revenues from sales to the customers. See Note 18 Warrants
