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

Impact of Recently Adopted Acco

Impact of Recently Adopted Accounting Standards	6 Months Ended

Impact of Recently Adopted Accounting Standards	Note 2. Impact of Recently Adopted Accounting Standards Adoption of new accounting standards There are two permitted transition methods under the new standard, the full retrospective method or the modified retrospective method. Under the full retrospective method, the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown on the face of the financial statements being presented. Under the modified retrospective method, the cumulative effect of applying the standard would be recognized at the date of the initial application of the standard and the effect of the prior periods would be calculated and shown through a cumulative effect change in retained earnings. ARRIS adopted the standard using the modified retrospective method on January 1, 2018. (See Note 3 Revenue from Contracts with Customers In January 2016, the FASB issued an update to amend certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Under this standard, certain equity investments are measured at fair value with changes recognized in current period earnings as opposed to other comprehensive income (loss). This guidance is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. ARRIS adopted the standard on January 1, 2018 by recording a cumulative-effect adjustments 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 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 end-of-period 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 any impact on the Company’s consolidated financial position and results of operations. Accounting standards issued but not yet effective right-of-use non-lease The Company has established a project management team to analyze the impact of this standard, including its current accounting policies and practices to identify potential impacts that would result from the application of this standard. The Company’s adoption process of the new standard is ongoing, including evaluating and quantifying the impact on its consolidated financial statements, identifying the population of leases (and embedded leases), implementing a selected technology solution and collecting and validating lease data. The Company expects its lease obligations designated as operating leases (as disclosed in Note 23 to the audited consolidated financial statements in its most recent Annual Report on Form 10-K) In January 2017, the FASB issued an accounting standard update that clarifies the definition of a business to help companies evaluate whether acquisition or disposal transactions should be accounted for as asset groups or as businesses. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a prospective basis. The impact of this accounting standard update will be facts and circumstances dependent, but the Company expects, that in some situations, transactions that were previously accounted for as business combinations or disposal transactions will be accounted for as asset purchases or asset sales under the accounting standard update. In August 2017, the FASB issued an accounting standard which eliminates the requirement to separately measure and report hedge ineffectiveness and requires companies to recognize all elements of hedge accounting that impact earnings in the same income statement line item where the hedged item resides. The standard includes new alternatives for measuring the hedged item for fair value hedges of interest rate risk and eases the requirements for effectiveness testing, hedge documentation and applying the critical terms match method. Finally, the standard introduces new alternatives that permit companies to reduce the risk of material error if the shortcut method is misapplied. The accounting standard is effective beginning January 1, 2019 and is required to be applied prospectively. The Company is currently assessing the potential impact of the adoption of this standard on its Consolidated Financial Statements. In February 2018, the FASB issued an accounting standard which allows companies to reclassify stranded tax effects resulting from the U.S. 2017 Tax Cuts and Jobs Act, from accumulated other comprehensive income to retained earnings. The guidance also requires certain new disclosures regardless of the election. The accounting standard is effective in the first quarter of fiscal 2020, and earlier adoption is permitted. The Company is currently assessing the potential impact of the adoption of this standard on its Consolidated Financial Statements.

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

The majority of ARRIS’ 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 4. Business Acquisition Acquisition of Ruckus Wireless and ICX Switch business On December 1, 2017, ARRIS completed the acquisition of Ruckus Wireless and ICX Switch business (“Ruckus Networks”). The total cash paid was approximately $761.0 million (net of estimated adjustments for working capital and noncash settlement of pre-existing With this acquisition, ARRIS expands its leadership in converged wired and wireless networking technologies beyond the home into the education, public venue, enterprise, hospitality, and multi-dwelling unit markets. The preliminary estimated goodwill of $308.2 million arising from the acquisition is attributable to the strategic opportunities and synergies that are expected to arise from the acquisition of Ruckus Networks and the workforce of the acquired business. Goodwill has been preliminarily assigned to our new Enterprise reporting unit as of June 30, 2018. The Company will finalize the assignment during the measurement period. A portion of the goodwill is expected to be deductible for income tax purposes. The following table summarizes the fair value of consideration transferred for Ruckus Networks (in thousands): Cash consideration $ 779,743 Estimated working capital adjustments (16,371 ) Non-cash (1) (2,359 ) Total consideration transferred $ 761,013 (1) Non-cash Total consideration excludes $61.5 million paid for the cash settlement of stock-based awards for which vesting was accelerated as contemplated in the purchase agreement.

These adjustments have been recorded prospectively in the first six months of 2018. The acquisition was accounted for using the acquisition method of accounting, which requires, among other things, that the assets acquired, and liabilities assumed be recognized at their acquisition date fair values, with any excess of the consideration transferred over the estimated fair values of the identifiable net assets acquired recorded as goodwill. The accounting for the business combination is based on currently available information and is considered preliminary. The Company has not received a final valuation report from the independent valuation expert for acquired property, plant and equipment and intangible assets. In addition, the Company is still gathering information about income taxes and deferred income tax assets and liabilities, accounts receivables, warranty obligations, other assets and accrued liabilities based on facts that existed as of the date of the acquisition. The final accounting for the business combination may differ materially from that presented in these unaudited consolidated financial statements. The $494.7 million of acquired intangible assets are comprised of the following (in thousands): Preliminary Estimated Weighted Technology and patents $ 217,900 5.4 Customer contracts and relationships 195,400 10.0 Tradenames 55,400 indefinite Trademarks and tradenames 10,700 10.0 Backlog 15,300 0.3 Total estimated fair value of intangible assets $ 494,700 The fair value of trade accounts receivable is $25.0 million with the gross contractual amount being $26.2 million. The Company expects $1.2 million to be uncollectible. The Company incurred acquisition related costs of $0.6 million and $0.7 million during the three and six months ended June 30, 2018, respectively. This amount was expensed by the Company as incurred and is included in the Consolidated Statement of Operations in the line item titled “Integration, acquisition, restructuring and other costs”. The Ruckus Networks business contributed revenues of approximately $343.8 million to our consolidated results for the six months ended June 30, 2018.

Fair Value Measurement

Fair Value Measurement	6 Months Ended
	Jun. 30, 2018
Fair Value Measurement	Note 7. Fair Value Measurement Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S GAAP establishes a fair value hierarchy that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities. To increase consistency and comparability in fair value measurements, the FASB has established a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels. An asset or liability’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the measurement of its fair value. The three levels of input defined by U.S GAAP are as follows: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. 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 table presents the Company’s investment assets (excluding equity and cost method investments) and derivatives measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017 (in thousands): June 30, 2018 Level 1 Level 2 Level 3 Total Certificates of deposit (non-U.S.) $ — $ 46,698 $ — $ 46,698 Corporate obligations — 14 — 14 Money markets 37 — — 37 Mutual funds 82 — — 82 Other investments — 5,529 — 5,529 Interest rate derivatives — asset derivatives — 21,077 — 21,077 Interest rate derivatives — liability derivatives — (377 ) — (377 ) Foreign currency contracts — asset position — 4,598 — 4,598 Foreign currency contracts — liability position — (166 ) — (166 ) December 31, 2017 Level 1 Level 2 Level 3 Total Certificates of deposit (non-U.S.) $ — $ 12,809 $ — $ 12,809 Corporate bonds — 11,065 — 11,065 Corporate obligations — 13 — 13 Money markets 38 — — 38 Mutual funds 79 — — 79 Other investments — 5,588 — 5,588 Interest rate derivatives — asset derivatives — 10,156 — 10,156 Interest rate derivatives — liability derivatives — (4,024 ) — (4,024 ) Foreign currency contracts — asset position — 405 — 405 Foreign currency contracts — liability position — (8,802 ) — (8,802 ) In addition to the financial instruments included in the above table, certain nonfinancial assets and liabilities are measured at fair value on a nonrecurring basis in accordance with applicable authoritative guidance. This includes items such as nonfinancial assets and liabilities initially measured at fair value in a business combination (but not measured at fair value in subsequent periods) and nonfinancial long-lived asset groups measured at fair value for an impairment assessment. In general, nonfinancial assets including goodwill, other intangible assets and property and equipment are measured at fair value when there is an indication of impairment and are recorded at fair value only when any impairment is recognized. During the six months ended June 30, 2018, the Company recorded partial impairment of goodwill of $3.4 million related to our Cloud TV reporting unit, of which $1.2 million is attributable to the noncontrolling interest, respectively. During the fourth quarter of 2017, the Company recorded partial impairments of goodwill and indefinite-lived tradenames of $51.2 million and $3.8 million, respectively, acquired in the ActiveVideo acquisition and included as part of the Cloud TV reporting unit, of which $19.3 million is attributable to the noncontrolling interest. See Note 5 Goodwill and Intangible Assets The Company believes the principal amount of debt as of June 30, 2018 approximated fair value because of interest-bearing rates that are adjusted periodically, analysis of recent market conditions, prevailing interest rates, and other Company specific factors. The Company has classified the debt as a Level 2 item within the fair value hierarchy.

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities	6 Months Ended
	Jun. 30, 2018
Derivative Instruments and Hedging Activities	Note 8. Derivative Instruments and Hedging Activities Overview ARRIS is exposed to financial market risk, primarily related to foreign currency and interest rates. These exposures are actively monitored by management. To manage the volatility related to certain of these exposures, the Company enters a variety of derivative financial instruments. Management’s objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency and interest rates. ARRIS’s policies and practices are to use derivative financial instruments only to the extent necessary to manage exposures. ARRIS does not hold or issue derivative financial instruments for trading or speculative purposes. The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a specific risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives also may be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Cash Flow Hedges of Interest Rate Risk The Company’s senior secured credit facilities, which are comprised of (i) a “Term Loan A Facility”, (ii) a “Term Loan A-1 B-3 Indebtedness one-month A-1 one-month one-month The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in Accumulated Other Comprehensive Income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2018, such derivatives were used to hedge the variable cash flows associated with debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the three and six months ended June 30, 2018, approximately $0.1 million and $0.4 million expense has been recorded related to hedge ineffectiveness by the Company. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. Over the next 12 months, the Company estimates that an additional $7.2 million may be reclassified as a decrease to interest expense. The table below presents the impact the Company’s derivative financial instruments had on Consolidated Statement of Operations (in thousands): Location of Three months ended June 30, Six months ended June 30, AOCI into Income 2018 2017 2018 2017 Gain (Loss) Recognized in OCI on Derivatives (Effective Portion) Interest expense $ 5,280 $ (2,787 ) $ 14,381 $ (733 ) Amounts Reclassified from Accumulated OCI into Income (Effective Portion) Interest expense (551 ) 590 (248 ) 1,795 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 June 30, 2018 December 31, 2017 Interest rate derivatives — asset derivatives Other current assets 7,132 3,590 Interest rate derivatives — asset derivatives Other assets 13,945 6,566 Interest rate derivatives — liability derivatives Other accrued liabilities — (3,053 ) Interest rate derivatives — liability derivatives Other noncurrent liabilities (377 ) (971 ) Credit-risk-related Contingent Features Each of ARRIS’s agreements with its derivative counterparties contains a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company’s default on the indebtedness. As of June 30, 2018 and December 31, 2017, the fair value of derivatives, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was a net asset position of $20.7 million and $6.1 million, respectively. As of June 30, 2018, the Company has not posted any collateral related to these agreements nor has it required any of its counterparties to post collateral related to these or any other agreements. Non-designated The Company has U.S. dollar functional currency entities that bill certain international customers in their local currency and foreign functional currency entities that procure in U.S. dollars. ARRIS also has certain predictable expenditures for international operations in local currency. Additionally, certain intercompany transactions are denominated in foreign currencies and subject to revaluation. To mitigate the volatility related to fluctuations in the foreign exchange rates for certain exposures, ARRIS has entered into various foreign currency contracts. As of June 30, 2018, the Company had forward contracts with notional amounts totaling 30 million euros which mature throughout 2018, forward contracts with a total notional amount of 30 million Australian dollars which mature throughout 2018 and 2019, forward contracts with notional amounts totaling 15 million Canadian dollars which mature throughout 2018, forward contracts with notional amounts totaling 40 million British pounds which mature throughout 2018 and forward contracts with notional amounts totaling 479.2 million South African rand which mature throughout 2018 and 2019. 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 Operations. The maximum time frame for ARRIS’s derivatives is currently 12 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 June 30, 2018 December 31, 2017 Foreign exchange contracts — asset derivatives Other current assets $ 4,598 $ 405 Foreign exchange contracts — liability derivatives Other accrued liabilities (166 ) (8,202 ) Foreign exchange contracts — liability derivatives Other non-current liabilities — (600 ) The change in the fair values of ARRIS’s derivatives not designated as hedging instruments recorded in the Consolidated Statements of Operations were as follows (in thousands): Statement of Operations Location Three months ended June 30, Six months ended June 30, 2018 2017 2018 2017 Foreign exchange contracts (Gain) loss on foreign currency $ (16,350 ) $ 9,612 $ (8,882 ) $ 16,319

No minimum funding contributions are required in 2018 under the Company’s U.S. defined benefit plan. During the three and six months ended June 30, 2018, the Company made a minimum funding contribution of $0.3 million and $1.4 million, respectively, related to its Taiwan pension plan. During the three and six months ended June 30, 2017, the Company made a minimum funding contribution of $0.3 and $0.6 million, respectively, related to its Taiwan pension plan. In late 2017, the Company commenced the process of terminating its U.S. defined benefit pension plan. Ultimate plan termination is subject to regulatory approval and to prevailing market conditions and other considerations. In the event approvals are received and the Company proceeds with effecting termination, settlement of the plan obligations is expected to occur in 2019. If the settlement occurs as expected in 2019, the plan’s deferred actuarial losses remaining in accumulated other comprehensive income (loss) at that time will be recognized as expense.

Guarantees

Guarantees	Note 10. Guarantees Warranty ARRIS provides warranties of various lengths to customers based on the specific product and the terms of individual agreements. The Company provides for the estimated cost of product warranties based on historical trends, the embedded base of product in the field, failure rates, and repair costs at the time revenue is recognized. Expenses related to product defects and unusual product warranty problems are recorded in the period that the problem is identified. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its suppliers, the estimated warranty obligation could be affected by changes in ongoing product failure rates, material usage and service delivery costs incurred in correcting a product failure, as well as specific product failures outside of ARRIS’s baseline experience. If actual product failure rates, material usage or service delivery costs differ from estimates, revisions (which could be material) would be recorded to the warranty liability. The Company offers extended warranties and support service agreements on certain products. Revenue from these agreements is deferred at the time of the sale and recognized on a straight-line basis over the contract period. Costs of services performed under these types of contracts are charged to expense as incurred, which approximates the timing of the revenue stream. Information regarding the changes in ARRIS’s aggregate product warranty liabilities for the six months ended June 30, 2018 was as follows (in thousands): Balance at December 31, 2017 $ 76,089 Accruals related to warranties (including changes in assumptions) 15,378 Settlements made (in cash or in kind) (23,010 ) Balance at June 30, 2018 $ 68,457 The decline in the warranty accrual resulted from lower sales volume of CPE products, accompanied by settlement of warranty claims for amounts less than their previously recorded value.

As a condition of sale, the Company will indemnify the buyer for certain environmental obligations up to $7.0 million. The assets have been reclassified as held for sale and were measured at their carrying amount. Total assets held for sale at June 30, 2018 were $58.1 million, which is reported in the Consolidated Balance Sheets as a component of “Other current assets.” The sale is expected to close in the second half of 2018.

This initiative affected all segments. The liability for the plan is expected to be paid in 2018. In 2017, ARRIS recorded restructuring charges of $13.3 million related to severance and employee termination benefits for 195 employees. This initiative affected all segments. The liability for the plan has been materially settled as of June 30, 2018. In first quarter of 2016, ARRIS completed its acquisition of Pace. ARRIS initiated restructuring plans as a result of the combination that focuses on the rationalization of personnel, facilities and systems across the ARRIS organization. The estimated cost recorded during 2016 was approximately $96.3 million. The restructuring plan affected approximately 1,545 employees across the company. The remaining liability is expected to be settled in 2018. This amount is included in the Consolidated Statement of Operations in the line item titled “Integration, acquisition, restructuring and other costs”. Contractual obligations cease-use During the year ended December 31, 2017, the Company exited three facilities and recorded a charge of $5.7 million. Acquisition During the three and six months ended June 30, 2018, acquisition expenses were approximately $0.6 million and $0.7 million, respectively. During the three and six months ended June 30, 2017, acquisition expenses were approximately $2.3 million and $4.7 million, respectively. These expenses related to the acquisition of the Ruckus Networks and consisted of banker and other fees. Integration Integration expenses of approximately $1.1 million and $4.0 million were recorded during the three and six months ended June 30, 2018, respectively. Integration expenses of approximately $0.3 million and $1.6 million were recorded during the three months and six months ended June 30, 2017, respectively.

The Fourth Amendment provided for a new Term B-3 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 A-1 The Third Amendment extended the maturity date of the Term A Loans and the Revolving Credit Facility to October 17, 2022.

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 Interest rates on borrowings under the senior secured credit facilities are set forth in the table below.

Segment Information

Segment Information	6 Months Ended

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

For the three months ended June 30, 2018 and 2017, approximately 2.0 million and 3.4 million of the equity-based awards were excluded from the computation of diluted earnings per share. For the six months ended June 30, 2018 approximately 1.9 million of the equity-based awards were excluded from the computation of diluted earnings per share. For the six months ended June 30, 2017, all the equity-based awards were excluded from the computation of diluted earnings per share. These exclusions are made if the Company has net losses, of which have an anti-dilutive effect. During the six months ended June 30, 2018, the Company issued 1.5 million ordinary shares related to the vesting of restricted shares, as compared to 2.6 million shares for the twelve months ended December 31, 2017. The warrants have a dilutive effect in those periods in which the average market price of the shares exceeds the current effective conversion price (under the treasury stock method) and are not subject to performance conditions. There is no vesting in the first half of 2018. The dilutive effect of these vested shares was immaterial. The Company has not paid cash dividends on its shares since its inception. Any future determination to pay dividends will be at the discretion of the Board of Directors and will be dependent on then-existing conditions, including the Company’s financial condition, results of operations, capital requirements, contractual and legal restrictions, business prospects and other factors that the Board considers relevant. The Credit Agreement governing the Company’s senior secured credit facilities contains restrictions on the Company’s ability to pay dividends on its ordinary shares.

Income Taxes

Income Taxes	6 Months Ended
	Jun. 30, 2018
Income Taxes	Note 18. Income Taxes ARRIS is subject to the U.K. statutory tax rate and a territorial corporate tax system. The U.K. statutory rate for 2018 is 19% as compared to 19.25% in 2017. The statutory rate in the U.K. decreased from 20% to 19% effective April 1, 2017. The Company’s statutory rate for 2017 represented the blended rate that was in effect for the year ended December 31, 2017 based on the 20% statutory rate that was effective for the first quarter of 2017 and the 19% rate effective for the remainder of 2017. The Tax Cuts and Jobs Act of 2017 (the “Act”) enacted on December 22, 2017 introduced significant changes to U.S. income tax law including, but not limited to, a reduction to the U.S. statutory tax rate from 35% to 21%, creation of new taxes on certain foreign-sourced earnings and certain intercompany payments, introduction of limits on interest deductibility, and increased limitations on certain executive compensation. Since the Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected during 2018, the Company considers the accounting of the impacts of the Act to be incomplete due to additional work necessary to determine re-measurement year-end As the Company obtains and analyzes more information and interprets the Act and any additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service (IRS), and other standard-setting bodies, the Company may adjust the provisional amounts. Those adjustments may materially affect the provision for income taxes and effective tax rate in the period in which the adjustments are made. The only significant adjustments made during the six months ended June 30, 2018 were a direct result of the acquisition accounting adjustments made during the quarters for fair value adjustments. As a result of the change to the fair value of certain assets and liabilities, the gross deferred tax amounts associated with those assets and liabilities also changed. The fair value adjustments are as of the acquisition date, December 1, 2017, resulting in the gross deferred tax impacts being measured at the applicable enacted tax rate of 35% on that date. These deferred tax impacts were then remeasured to 21% to reflect the enacted rate as of December 22, 2017. As a result of these acquisition accounting measurement period adjustments, the Company recorded discrete tax expense of $2.7 million and tax benefit of $5.6 million during the first quarter of 2018 and second quarter of 2018, respectively.

The difference between the U.K. federal statutory income tax rate, 19% and 19.25%, respectively, and our effective income tax rate for the 2018 and 2017 periods is primarily due to the benefits of other foreign income tax regimes and the U.S. federal research and development credits . The Company’s effective income tax rate for the six months ended June 30, 2018 was impacted by $1.8 million of expense related to excess book deductions for stock based compensation, $2.3 million of expense related to changes in permanent reinvestment assertions, offset by $1.3 million of benefit related to the release of uncertain tax positions due to settlement of audits, $2.8 million of benefit related to the effects of tax rate changes in the U.S., and $4.2 million of benefit related to an internal restructuring to move certain Ruckus Networks intangible property into the U.S. The Company’s effective income tax rate for the six months ended June 30, 2017 was impacted by $8.0 million related to the intra-entity sale of an asset, offset by $4.0 million of benefit related to statute closures for uncertain tax positions and $4.8 million of benefit related to the reversal of interest related to uncertain tax positions.

(2) Includes an aggregate of 557,715 shares (approximately $13.7 million) pending settlement as of June 30, 2018. Upon completing the combination in connection with the Pace acquisition, ARRIS International plc conducted a court-approved process in accordance with section 641(1)(b) of the U.K. Companies Act 2006, pursuant to which the Company reduced its stated share capital and thereby increased its distributable reserves or excess capital out of which ARRIS may legally pay dividends or repurchase shares. Distributable reserves are not linked to a U.S. GAAP reported amount. In 2016, the Company’s Board of Directors approved a $300 million share repurchase authorization replacing all prior programs. In early 2017, the Board authorized an additional $300 million for share repurchases, and authorized an additional $300 million for repurchases again in March 2018. During the first quarter of 2018, the Company repurchased 1.0 million shares of its ordinary shares for $25.0 million at an average share price of $25.35. During the second quarter of 2018, the Company repurchased 4.0 million shares of its ordinary shares for $99.9 million at an average share price of $25.29. The remaining authorized amount for share repurchases under this plan was $400.1 million as of June 30, 2018. Since the end of the second quarter through August 1, 2018, we have repurchased an additional 2.0. million ordinary shares for approximately $50.0 million. The remaining authorized amount for share repurchases under this plan was $350.0 million as of August 1, 2018. In August 2018, we announced that we intend to purchase a minimum of $400 million of our ordinary shares in 2018, subject to market conditions. 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 when such company is not traded on a recognized investment exchange in the U.K. This shareholder approval lasts for a maximum period of five years. Prior to and in connection with the Pace combination, the Company obtained approval to purchase its own shares. This authority to repurchase shares terminates in January 2021, unless otherwise reapproved by the Company’s shareholders.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended
	Jun. 30, 2018
Commitments and Contingencies	Note 22. Commitments and Contingencies Legal Proceedings The Company accrues a liability for legal contingencies when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of the loss. The Company reviews these accruals and adjusts them to reflect ongoing negotiations, settlements, rulings, advice of legal counsel and other relevant information. To the extent new information is obtained and the Company’s views on the probable outcomes of claims, suits, assessments, investigations or legal proceedings change, changes in the Company’s accrued liabilities would be recorded in the period in which such determinations are made. Unless noted otherwise, the amount of liability is not probable, or the amount cannot be reasonably estimated; and, therefore, accruals have not been made. Due to the nature of the Company’s business, it is subject to patent infringement claims, including current suits against it or one or more of its wholly-owned subsidiaries, or one or more of our customers who may seek indemnification from us, alleging infringement by various Company products and services. The Company believes that it has meritorious defenses to the allegation made in its pending cases and intends to vigorously defend these lawsuits; however, it is currently unable to determine the ultimate outcome of these or similar matters. Accordingly, with respect to these proceedings, we are currently unable to reasonably estimate the possible loss or range of possible losses. In addition, the Company is a defendant in various litigation matters generally arising out of the normal course of business. (See Part II, Item 1 “Legal Proceedings” for additional details)
