Accounting Policies [Abstract]
Background and Basis of Presentation	1. BACKGROUND AND BASIS OF PRESENTATION Background CommScope Holding Company, Inc., along with its direct and indirect subsidiaries (CommScope or the Company), is a global provider of infrastructure solutions for communication and entertainment networks. The Company’s solutions for wired and wireless networks enable service providers including cable, telephone and digital broadcast satellite operators and media programmers to deliver media, voice, Internet Protocol (IP) data services and Wi-Fi to their subscribers and allow enterprises to experience constant, wireless and wired connectivity across complex and varied networking environments. The Company’s solutions are complemented by a broad array of services including technical support, systems design and integration. CommScope is a leader in digital video and IP television distribution systems, broadband access infrastructure platforms and equipment that delivers data and voice networks to homes. CommScope’s global leadership position is built upon innovative technology, broad solution offerings, high-quality and cost-effective customer solutions, and global manufacturing and distribution scale. On April 4, 2019, the Company completed the acquisition of ARRIS International plc (ARRIS) (the Acquisition) in an all-cash transaction with a total purchase price of approximately $7.7 billion, including debt assumed. See Note 2 for additional discussion of the Acquisition. As of January 1, 2020, the Company reorganized its internal management and reporting structure as part of the integration of the Acquisition. The reorganization changed the information regularly reviewed by the Company’s chief operating decision maker for purposes of allocating resources and assessing performance. As a result, the Company now reports financial performance for the 2020 year based on four operating segments: Broadband Networks (Broadband), Home Networks (Home), Outdoor Wireless Networks (OWN) and Venue and Campus Networks (VCN). These four segments represent non-aggregated reportable operating segments. Prior to this change, the Company operated and reported five operating segments: Connectivity Solutions, Mobility Solutions, Customer Premises Equipment, Network and Cloud and Ruckus Networks. All prior period amounts in these condensed consolidated financial statements have been recast to reflect these operating segment changes. Basis of Presentation The accompanying condensed consolidated financial statements are unaudited and reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The results of operations for these interim periods are not necessarily indicative of the results of operations to be expected for any future period or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current year presentation. The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and are presented in accordance with the applicable requirements of Regulation S-X. Accordingly, these financial statements do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (the 2019 Annual Report). The significant accounting policies followed by the Company are set forth in Note 2 within the Company’s audited consolidated financial statements included in the 2019 Annual Report. Other than the enhancements described below to the allowance for doubtful accounts policy as a result of the adoption of Accounting Standards Update (ASU) No. 2016-13, Measurement of Credit Losses on Financial Instruments Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable and contract assets for unbilled receivables are stated at the amount owed by the customer, net of allowances for estimated doubtful accounts, discounts, returns and rebates. The Company measures the allowance for doubtful accounts using an expected credit loss model, which uses a lifetime expected loss allowance for all trade accounts receivable and contract assets. To measure the expected credit losses, trade accounts receivable and contract assets are grouped based on shared credit risk characteristics and the days past due. Contract assets relate to unbilled work in progress and have substantially the same risk characteristics as trade accounts receivable for the same types of contracts. Therefore, the Company has concluded that the expected loss rates for trade accounts receivables are a reasonable approximation of the loss rates for the contract assets. In calculating an allowance for doubtful accounts, the Company uses its historical experience, external indicators and forward-looking information to calculate expected credit losses using an aging method. The Company assesses impairment of trade accounts receivable on a collective basis as they possess shared credit risk characteristics which have been grouped based on the days past due. The expected loss rates are based on the payment profiles of sales over the preceding thirty-six months and the corresponding historical credit losses experienced within this period. The historical loss rates are adjusted to reflect current and forward-looking information on macroeconomic factors affecting the ability of the customers to settle their trade accounts receivable. Concentrations of Risk and Related Party Transactions Net sales to Comcast Corporation and affiliates (Comcast) accounted for 12% and 10% of the Company’s total net sales during the three and six months ended June 30, 2020, respectively. No other direct customer accounted for 10% or more of the Company’s total net sales. No direct customer accounted for 10% 10% The Company relies on sole suppliers or a limited group of suppliers for certain key components, subassemblies and modules and a limited group of contract manufacturers to manufacture a significant portion of its products. Any disruption or termination of these arrangements could have a material adverse impact on the Company’s results of operations. As of June 30, 2020, funds affiliated with Carlyle Partners VII S1 Holdings, L.P. (Carlyle) owned 100% of the Series A Convertible Preferred Stock (the Convertible Preferred Stock), which was issued to Carlyle to fund the Acquisition. See Note 11 for further discussion of the Convertible Preferred Stock. Other than transactions related to the Convertible Preferred Stock, there were no material related party transactions for the three or six months ended June 30, 2020. Product Warranties The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over various periods, depending upon the product subject to the warranty and the terms of the individual agreements. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material. The following table summarizes the activity in the product warranty accrual, included in accrued and other liabilities and other noncurrent liabilities: Three Months Ended Six Months Ended June 30, June 30, 2020 2019 2020 2019 Product warranty accrual, beginning of period $ 57.3 $ 14.1 $ 61.0 $ 15.6 Obligation assumed under ARRIS acquisition — 57.4 — 57.4 Provision for warranty claims 3.4 6.5 7.4 6.0 Warranty claims paid (4.9 ) (11.5 ) (12.0 ) (12.4 ) Foreign exchange 0.1 0.1 (0.5 ) — Product warranty accrual, end of period $ 55.9 $ 66.6 $ 55.9 $ 66.6 Commitments and Contingencies The Company is party to certain intellectual property claims and periodically receives notices asserting that its products infringe on another party’s patents and other intellectual property rights. These claims and assertions, whether against the Company directly or against its customers, could require the Company to pay damages, royalties, stop offering the relevant products and/or cease other activities. The Company may also be called upon to indemnify certain customers for costs related to products sold to such customers. While the outcome of the claims and notices is uncertain and a reasonable estimate of the loss from unfavorable outcomes in certain of these matters cannot be determined, an adverse outcome could result in a material loss. As of June 30, 2020, the Company had a liability of $39.8 million recorded in accrued and other liabilities on the Condensed Consolidated Balance Sheets related to certain intellectual property assertions that have been settled or are in process of settlement. Of that amount, $27.1 million was attributed to periods prior to the Acquisition and was previously recorded as a liability on the opening balance sheet. For the three and six months ended June 30, 2020, $7.5 million and $12.8 million, respectively, was recorded as a charge to cost of sales in the Condensed Consolidated Statements of Operations impacting the Broadband and Home segments. One matter, making up $19.0 million of the total recorded liability, was settled in July 2020 and the settlement is payable in the second half of 2020. The Company is either a plaintiff or a defendant in certain other pending legal matters in the normal course of business. Management believes none of these other pending legal matters will have a material adverse effect on the Company’s business or financial condition upon final disposition. In addition, the Company is subject to various federal, state, local and foreign laws and regulations governing the use, discharge, disposal and remediation of hazardous materials. Compliance with current laws and regulations has not had, and is not expected to have, a materially adverse effect on the Company’s financial condition or results of operations. Asset Impairments Goodwill is tested for impairment annually or at other times if events have occurred or circumstances exist that indicate the carrying value of the reporting unit may exceed its fair value. See Notes 3 and 8 for discussion of goodwill impairment charges during the three and six months ended June 30, 2020. There were no goodwill impairments identified during the three or six months ended June 30, 2019. Property, plant and equipment and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, based on the undiscounted cash flows expected to be derived from the use and ultimate disposition of the assets. Assets identified as impaired are adjusted to estimated fair value. Equity investments without readily determinable fair values are evaluated each reporting period for impairment based on a qualitative assessment and are then measured at fair value if an impairment is determined to exist. Other than certain assets impaired as a result of restructuring actions, there were no definite-lived intangible or other long-lived asset impairments identified during the three or six months ended June 30, 2020 or 2019. Income Taxes For the three and six months ended June 30, 2020, the Company’s effective tax rate was 4.5% and 8.8%, respectively, and the Company recognized a tax benefit of $15.1 million on a pretax loss of $336.2 million and $46.5 million on a pretax loss of $527.5 million, respectively. The Company’s tax benefit was less than the statutory rate of 21.0% in both the three and six months ended June 30, 2020 primarily due to a goodwill impairment charge of $206.7 million for which minimal tax benefits were recorded and $20.3 million and $21.9 million, respectively, of tax expense related to state valuation allowances. Excess tax costs of $3.7 million and $7.8 million related to equity compensation awards also impacted the tax benefit unfavorably for the three and six months ended June 30, 2020, respectively. For the three and six months ended June 30, 2019, the Company’s effective income tax rate was 10.1% and 9.6%, respectively, and the Company recognized a tax benefit of $37.5 million on a pretax loss of $371.5 million and a tax benefit of $35.9 million on a pretax loss of $372.2 million, respectively. The Company’s tax benefit was unfavorably impacted by the impact of U.S. anti-deferral provisions and foreign withholding taxes, but this impact was partially offset by the favorable impact of federal tax credits for the three and six months ended June 30, 2019. The impact of excess tax costs related to equity-based compensation awards was not material for the three and six months ended June 30, 2019. Earnings (Loss) Per Share Basic earnings (loss) per share (EPS) is computed by dividing net income (loss), less any dividends and deemed dividends related to the Convertible Preferred Stock, by the weighted average number of common shares outstanding during the period. The numerator in diluted EPS is based on the basic EPS numerator adjusted to add back any dividends and deemed dividends related to the Convertible Preferred Stock, subject to antidilution requirements. The denominator used in diluted EPS is based on the basic EPS computation plus the effect of potentially dilutive common shares related to the Convertible Preferred Stock and equity-based compensation plans, subject to antidilution requirements. For the three and six months ended June 30, 2020, 17.0 million and 16.6 million shares, respectively, of outstanding equity-based compensation awards were not included in the computation of diluted EPS because the effect was either antidilutive or the performance conditions were not met. Of those amounts, for the three and six months ended June 30, 2020, 4.3 million and 4.4 million shares, respectively, would have been considered dilutive if the Company had not been in a net loss position. For the three and six months ended June 30, 2019, 12.2 million shares and 8.9 million shares, respectively, were not included in the computation of diluted EPS because the effect was either antidilutive or the performance conditions were not met. Of those amounts, for the three and six months ended June 30, 2019, 2.2 million shares and 2.5 million shares, respectively, would have been considered dilutive if the Company had not been in a net loss position. For the three and six months ended June 30, 2020, 36.9 million and 36.6 million, respectively, of as-if converted shares related to the Convertible Preferred Stock were excluded from the diluted share count because they were anti-dilutive; however, they would have been considered dilutive if the Company had not been in a net loss position.

The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including trade accounts receivable. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842. The Company adopted Topic 326 using the modified retrospective method for all financial assets measured at amortized cost, which are primarily trade accounts receivable and contract assets for the Company. Results for reporting periods beginning after January 1, 2020 are presented under Topic 326 while prior period amounts continue to be reported in accordance with previously applicable U.S. GAAP. The impact of adopting Topic 326 as of January 1, 2020 was not material to the consolidated financial statements. Issued but Not Adopted In March 2020, the Financial Accounting Standards Board (FASB) issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to transactions affected by reference rate reform if certain criteria are met. These transactions include contract modifications, hedging relationships, and sale or transfer of debt securities classified as held-to-maturity. The Company can elect to apply the amendments as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this guidance on the consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01 , Investments - Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The new guidance is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. T he amendments in this guidance clarify the interaction of accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. ASU No. 2020-01 is effective for the Company as of January 1, 202 1 and e arly adoption is permitted. The Company is evaluating the impact of the new guidance on the consolidated financial statements. In December 2019 the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes .

Business Combinations [Abstract]
Acquisitions	2. ACQUISITIONS On April 4, 2019, the Company acquired all of the issued ordinary shares of ARRIS in an all cash transaction with a total consideration of approximately $7.7 billion, including debt assumed. ARRIS is a global leader in entertainment, communications and networking technology. The combined company is expected to drive profitable growth in new markets, shape the future of wired and wireless communications, and position the 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. During the first quarter of 2020, the Company completed its acquisition accounting and made the following adjustments to the provisional amounts that were previously recorded: • An increase of $13.1 million in accrued liabilities and an increase of $3.2 million in deferred tax assets due to an adjustment of certain pre-acquisition contingencies with a corresponding $9.9 million increase to goodwill. • An increase in deferred tax assets of $20.8 million related to the release of valuation allowances for certain state income tax credits with a corresponding decrease to goodwill. • A decrease in deferred tax liabilities of approximately $4.7 million, an increase in income tax payable of $6.7 million and a decrease in unrecognized tax benefits of approximately $0.9 million with a corresponding $1.1 million increase to goodwill. The Company recorded these amounts as measurement period adjustments because the information was known as of the acquisition date but the analysis was finalized in the first quarter of 2020.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill	3. GOODWILL As a result of the change in segments as discussed in Note 1, goodwill was reallocated from the previous segments to the new segments. The following table presents goodwill after the reallocation by new reportable segment: Broadband Home OWN VCN Total Goodwill, gross at December 31, 2019 $ 3,355.1 $ 402.1 $ 666.0 $ 1,635.6 $ 6,058.8 Adjustments to preliminary purchase price (7.1 ) (1.3 ) — (1.4 ) (9.8 ) Foreign exchange and other (11.5 ) (1.3 ) (2.2 ) (9.0 ) (24.0 ) Goodwill, gross at June 30, 2020 3,336.5 399.5 663.8 1,625.2 6,025.0 Accumulated impairment charges at December 31, 2019 (193.6 ) (192.8 ) (159.5 ) (41.2 ) (587.1 ) Impairment charges for the six months ended June 30, 2020 — (206.7 ) — — (206.7 ) Accumulated impairment at June 30, 2020 (193.6 ) (399.5 ) (159.5 ) (41.2 ) (793.8 ) Goodwill, net at June 30, 2020 $ 3,142.9 $ — $ 504.3 $ 1,584.0 $ 5,231.2 The Company’s change in segments as of January 1, 2020 resulted in a realignment of its existing reporting units. Although the reporting units were realigned under the new segments, the Company’s reporting units remained the same except for where two reporting units have been combined into a new reporting unit. In this case, goodwill was simply combined in the new reporting units. Since the composition of the reporting units and the assignment of goodwill to the reporting units were unaffected, an interim goodwill impairment test due to the change in segments was not performed in the first quarter of 2020. During the second quarter of 2020, the Company determined that indicators of goodwill impairment existed for the Home Networks reporting unit due to lower projected operating results, primarily from the accelerated decline in video devices. This trend is projected to continue as consumers adopt the use of other streaming applications and has been further impacted by the macro-economic effects caused by the new strain of coronavirus (COVID-19). The Company performed a quantitative goodwill impairment test during the second quarter of 2020 and recorded a $206.7 million goodwill impairment charge relating to the Home Networks reporting unit in the asset impairments line on the Condensed Consolidated Statement of Operations. This reflects a full impairment of the remaining goodwill in the Home segment, and as such, the Home segment has no remaining goodwill balance as of June 30, 2020. Estimating the fair value of a reporting unit involves uncertainties because it requires management to develop numerous assumptions, including assumptions about the future growth and potential volatility in revenues and costs, capital expenditures, industry economic factors and future business strategy. Changes in projected revenue growth rates, projected operating income margins or estimated discount rates due to uncertain market conditions, loss of one or more key customers, changes in the Company’s strategy, changes in technology or other factors could negatively affect the fair value in one or more of the Company’s reporting units and result in a material impairment charge in the future.

Senior Secured Credit Facilities In April 2020, the Company borrowed $250.0 million under the senior secured asset-based revolving credit facility (the Revolving Credit Facility). As of June 30, 2020, the Company had $250.0 million outstanding borrowings under the Revolving Credit Facility and had availability of $521.6 million, after giving effect to borrowing base limitations and outstanding letters of credit. During the three and six months ended June 30, 2020, the Company made quarterly scheduled amortization payments of $8.0 million and $16.0 million, respectively, on the senior secured term loan due in 2026 (the 2026 Term Loan). The current portion of long-term debt reflects $32.0 million of repayments due under the 2026 Term Loan. No portion of the 2026 Term Loan was reflected as a current portion of long-term debt as of June 30, 2020 related to the potentially required excess cash flow payment because the amount that may be payable in 2021, if any, cannot currently be reliably estimated.

Fair Value Disclosures [Abstract]
Fair Value Measurements	8. FAIR VALUE MEASUREMENTS The Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, debt instruments, interest rate derivatives and foreign currency contracts. For cash and cash equivalents, trade receivables and trade payables, the carrying amounts of these financial instruments as of June 30, 2020 and December 31, 2019 were considered representative of their fair values due to their short terms to maturity. The fair values of the Company’s debt instruments, interest rate derivatives and foreign currency contracts were based on indicative quotes. Fair value measurements using quoted prices in active markets for identical assets and liabilities fall within Level 1 of the fair value hierarchy, measurements using significant other observable inputs fall within Level 2, and measurements using significant unobservable inputs fall within Level 3. The carrying amounts, estimated fair values and valuation input levels of the Company’s debt instruments, interest rate derivatives and foreign currency contracts as of June 30, 2020 and December 31, 2019, are as follows: June 30, 2020 December 31, 2019 Carrying Amount Fair Value Carrying Amount Fair Value Valuation Inputs Assets: Foreign currency contracts $ 4.7 $ 4.7 $ 10.7 $ 10.7 Level 2 Liabilities: 5.00% senior notes due 2027 $ 750.0 675.5 $ 750.0 $ 696.4 Level 2 8.25% senior notes due 2027 1,000.0 1,027.7 1,000.0 1,052.5 Level 2 6.00% senior notes due 2025 1,500.0 1,448.6 1,500.0 1,501.7 Level 2 5.50% senior notes due 2024 650.0 661.7 650.0 656.0 Level 2 5.00% senior notes due 2021 50.0 50.0 150.0 149.9 Level 2 6.00% senior secured notes due 2026 1,500.0 1,537.5 1,500.0 1,595.6 Level 2 5.50% senior secured notes due 2024 1,250.0 1,262.5 1,250.0 1,302.1 Level 2 Senior secured term loan due 2026 3,176.0 3,025.1 3,192.0 3,219.9 Level 2 Senior secured revolving credit facility 250.0 246.9 — — Level 2 Foreign currency contracts 3.5 3.5 5.9 5.9 Level 2 Interest rate swap contracts 36.2 36.2 16.3 16.3 Level 2 Non-Recurring Fair Value Measurements During the second quarter of 2020, the Company recorded a pretax goodwill impairment charge of $206.7 million related to the Home Networks reporting unit in the Home segment (see Note 3). The fair value of the reporting unit was determined as of May 31, 2020 using a discounted cash flow (DCF) model. Under the DCF method, the fair value of a reporting unit is based on the present value of estimated future cash flows. The inputs to the DCF model are Level 3 valuation inputs. The se fair value estimates are based on pertinent information available to management as of the valuation date. Although management is not aware of any factors that would significantly affect these fair value estimates, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates, and current estimates of fair value may differ significantly from the amounts presented.

Segment Reporting [Abstract]
Segments and Geographic Information	9. SEGMENTS AND GEOGRAPHIC INFORMATION As of January 1, 2020, the Company reorganized its internal management and reporting structure as part of the integration of the Acquisition. The reorganization changed the information regularly reviewed by the Company’s chief operating decision maker for purposes of allocating resources and assessing performance. As a result, the Company is reporting financial performance based on four reportable segments: Broadband, Home, OWN and VCN. These reportable segments are based upon the nature of the products and services they offer. The Broadband segment provides an end-to-end product portfolio serving the telco and cable provider broadband market. The segment brings together the Network Cable and Connectivity business with the Network and Cloud business and includes converged cable access platform, passive optical networking, video systems, access technologies, fiber and coaxial cable, fiber and copper connectivity and hardened closures. The Home segment comprises the former Consumer Premises Equipment business and focuses on the future of the connected home and connected devices inside the home. The segment includes subscriber-based solutions that support broadband and video applications connecting cable, telecommunications and satellite service providers to a customer’s home and adds wireless connectivity or other wired connections integrating in-home devices together to enable the consumption of internet-based services and the delivery of broadcast, streamed and stored video to televisions and other connected devices. Broadband offerings include devices that provide residential connectivity to a service provider’s network, such as digital subscriber line and cable modems and telephony and data gateways which incorporate routing and Wi-Fi functionality. Video offerings include set top boxes that support cable, satellite and IPTV content delivery and include products such as digital video recorders, high definition set top boxes and hybrid set top devices. The OWN segment focuses on the macro and metro cell markets. The segment includes base station antennas, RF filters, tower connectivity, microwave antennas, metro cell products, cabinets, steel accessories, Spectrum Access System and Comsearch. As the Company’s wireless operator customers shift a portion of their 5G capital expenditures from the macro tower to the metro cell, the portfolio will strategically help to make the transition smooth and cost-effective. The VCN segment targets both public and private networks for campuses, venues, data centers and buildings. The segment combines Wi-Fi and switching, distributed antenna systems, licensed and unlicensed small cells and enterprise fiber and copper infrastructure.

Restructuring And Related Activities [Abstract]
Restructuring Costs	10. RESTRUCTURING COSTS The Company incurs costs associated with restructuring initiatives intended to improve overall operating performance and profitability. The costs related to restructuring actions are generally cash-based and primarily consist of employee-related costs, which include severance and other one-time termination benefits. In addition to the employee-related costs, the Company also records other costs associated to restructuring actions, such as impairment costs arising from unutilized real estate or equipment. As a result of prior restructuring and consolidation actions, the Company owns unutilized real estate and is attempting to sell or lease this unutilized space. Additional impairment charges may be incurred related to these or other excess assets, which are recorded as other associated costs. The Company’s net pretax restructuring charges, by segment, were as follows: Three Months Ended Six Months Ended June 30, June 30, 2020 2019 2020 2019 Broadband $ 8.9 $ 22.7 $ 14.0 $ 25.6 Home 4.9 15.1 7.4 15.1 OWN 3.9 1.9 8.0 5.8 VCN 1.9 6.7 13.9 12.3 Total $ 19.6 $ 46.4 $ 43.3 $ 58.8 Restructuring liabilities were included in the Company’s Condensed Consolidated Balance Sheets as follows: June 30, 2020 December 31, 2019 Accrued and other liabilities $ 25.9 $ 24.0 Other noncurrent liabilities 2.4 4.4 Total liability $ 28.3 $ 28.4 ARRIS Integration Restructuring Actions In anticipation of and following the Acquisition, the Company initiated a series of restructuring actions, which are currently ongoing, to integrate and streamline operations and achieve cost synergies. The activity within the liability established for the ARRIS integration restructuring actions was as follows: Employee- Related Costs Other Associated Costs Total Balance at March 31, 2020 $ 28.1 $ 1.7 $ 29.8 Additional charge recorded 19.6 — 19.6 Cash paid (22.2 ) — (22.2 ) Balance at June 30, 2020 $ 25.5 $ 1.7 $ 27.2 Balance at December 31, 2019 $ 23.1 $ 2.0 $ 25.1 Additional charge recorded 43.0 0.3 43.3 Cash paid (40.6 ) (0.3 ) (40.9 ) Non-cash items — (0.3 ) (0.3 ) Balance at June 30, 2020 $ 25.5 $ 1.7 $ 27.2 The ARRIS integration actions include headcount reductions in sales, engineering, marketing and administrative functions. The Company expects to make cash payments of $20.5 million during the remainder of 2020 and additional cash payments of $6.7 million between 2021 and 2022 to settle the announced ARRIS integration initiatives. The Company has recognized restructuring charges of $129.4 million since the Acquisition for integration and synergy actions. Additional restructuring actions related to the ARRIS integration are expected to be identified and the resulting charges and cash requirements are expected to be material. BNS Integration Restructuring Actions Following the acquisition of the Broadband Network Solutions (BNS) business in 2015, the Company initiated a series of restructuring actions to integrate and streamline operations and achieve cost synergies. The activity within the liability established for the BNS integration restructuring actions was as follows: Employee- Related Costs Balance at March 31, 2020 $ 2.2 Cash paid (1.1 ) Balance at June 30, 2020 $ 1.1 Balance at December 31, 2019 $ 3.3 Cash paid (2.2 ) Balance at June 30, 2020 $ 1.1 The BNS integration actions include the announced closures or reduction in activities at various U.S. and international facilities as well as headcount reductions in sales, marketing and administrative functions. The Company has recognized restructuring charges of $153.0 million since the BNS acquisition for integration actions. No additional restructuring actions are expected in connection with the BNS integration initiatives. The Company expects to make cash payments of $0.4 million during the remainder of 2020 and additional cash payments of $0.7 million between 2021 and 2022.

Stockholders' Equity	12. STOCKHOLDERS’ EQUITY Equity-Based Compensation Plans As of June 30, 2020, $182.3 million of total unrecognized compensation expense related to unvested stock options, restricted stock units (RSUs) and performance share units (PSUs) is expected to be recognized over a remaining weighted average period of 1.5 years. There were no significant capitalized equity-based compensation costs at June 30, 2020. The following table shows a summary of the equity-based compensation expense included in the Condensed Consolidated Statements of Operations: Three Months Ended Six Months Ended June 30, June 30, 2020 2019 2020 2019 Selling, general and administrative $ 17.7 $ 15.0 $ 30.7 $ 20.9 Cost of sales 5.2 3.1 9.0 4.0 Research and development 9.6 5.0 16.3 5.8 Total equity-based compensation expense $ 32.5 $ 23.1 $ 56.0 $ 30.7 Stock Options Stock options are awards that allow the recipient to purchase shares of the Company’s common stock at a fixed price. Stock options are granted at an exercise price equal to the Company’s stock price at the date of grant. These awards vest over three to five years following the grant date and have a contractual term of ten years. These awards vest based on a time-based component or a combination of time and performance-based components. The following table summarizes the stock option activity (in millions, except per share data and years): Shares Weighted Average Option Exercise Price Per Share Weighted Average Remaining Contractual Term in Years Aggregate Intrinsic Value Options outstanding at March 31, 2020 9.4 $ 17.71 Expired (0.1 ) 29.43 Forfeited (0.1 ) $ 22.77 Options outstanding at June 30, 2020 9.2 $ 17.57 6.6 $ 5.5 Options outstanding at December 31, 2019 9.6 $ 17.70 Exercised (0.1 ) $ 8.29 Expired (0.1 ) $ 30.15 Forfeited (0.2 ) $ 20.52 Options outstanding at June 30, 2020 9.2 $ 17.57 6.6 $ 5.5 Options vested at June 30, 2020 3.9 $ 15.84 3.5 $ 5.5 Options unvested at June 30, 2020 5.3 $ 18.86 8.9 $ — The exercise prices of outstanding options at June 30, 2020 were in the following ranges (in millions, except per share data and years): Options Outstanding Options Exercisable Range of Exercise Prices Shares Weighted Average Remaining Contractual Life in Years Weighted Average Exercise Price Per Share Shares Weighted Average Exercise Price Per Share $2.96 to $5.74 2.1 0.6 $ 5.74 2.1 $ 5.74 $5.75 to $22.99 5.8 8.8 $ 18.34 0.6 $ 17.72 $23.00 to $42.32 1.3 6.2 $ 33.38 1.2 $ 32.88 $2.96 to $42.32 9.2 6.6 $ 17.57 3.9 $ 15.84 The Company uses the Black-Scholes model to estimate the fair value of stock option awards at the date of grant. Key inputs and assumptions used in the model include the grant date fair value of common stock, exercise price of the award, the expected option term, the risk-free interest rate, stock price volatility and the Company’s projected dividend yield. The expected term represents the period over which the Company’s employees are expected to hold their options. The risk-free interest rate reflects the yield on zero-coupon U.S. treasury securities with a term equal to the option’s expected term. Expected volatility is derived based on the historical volatility of the Company’s stock. The Company’s projected dividend yield is zero. The Company believes the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in estimating the fair values of its stock options. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards. Subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company. There were no stock option awards granted during the three or six months ended June 30, 2020. The following table presents the weighted average assumptions used to estimate the fair value of stock option awards granted during the three and six months ended June 30, 2019. Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 Expected option term (in years) 6.3 6.3 Risk-free interest rate 2.2 % 2.2 % Expected volatility 40.0 % 40.0 % Weighted average exercise price $ 18.60 $ 18.60 Weighted average fair value at grant date $ 8.06 $ 8.06 Restricted Stock Units RSUs entitle the holder to shares of common stock after a vesting period that generally ranges from one to three years. The fair value of the awards is determined on the grant date based on the Company’s stock price. The following table summarizes the RSU activity (in millions, except per share data): Restricted Stock Units Weighted Average Grant Date Fair Value Per Share Non-vested share units at March 31, 2020 9.0 $ 17.24 Granted 6.4 $ 10.34 Vested and shares issued (0.1 ) $ 16.76 Forfeited (0.3 ) $ 17.59 Non-vested share units at June 30, 2020 15.0 $ 14.28 Non-vested share units at December 31, 2019 7.7 $ 22.30 Granted 9.6 $ 10.57 Vested and shares issued (1.8 ) $ 27.62 Forfeited (0.5 ) $ 18.48 Non-vested share units at June 30, 2020 15.0 $ 14.28 Performance Share Units Performance share units (PSUs) are stock-based awards in which the number of shares ultimately received by the employee depends on Company performance against specified targets. Such awards typically vest over three years and the number of shares issued can vary from 0% to 200% of the number of PSUs granted, depending on performance. The fair value of each PSU is determined on the date of grant based on the Company’s stock price. The ultimate number of shares issued and the related compensation cost recognized is based on the final performance metrics compared to the targets specified in the grants. The following table summarizes the PSU activity (in millions, except per share data): Performance Share Units Weighted Average Grant Date Fair Value Per Share Non-vested share units at March 31, 2020 2.6 $ 7.60 Granted 0.2 $ 10.32 Vested and shares issued (0.1 ) $ 6.67 Forfeited — Non-vested share units at June 30, 2020 2.7 $ 7.73 Non-vested share units at December 31, 2019 2.7 $ 12.47 Granted 0.2 $ 10.32 Vested and shares issued (0.1 ) $ 19.86 Forfeited (0.1 ) $ 8.98 Non-vested share units at June 30, 2020 2.7 $ 7.73

Background and Basis of Prese_2

Background and Basis of Presentation (Policies)	6 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements are unaudited and reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The results of operations for these interim periods are not necessarily indicative of the results of operations to be expected for any future period or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current year presentation. The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and are presented in accordance with the applicable requirements of Regulation S-X. Accordingly, these financial statements do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (the 2019 Annual Report). The significant accounting policies followed by the Company are set forth in Note 2 within the Company’s audited consolidated financial statements included in the 2019 Annual Report. Other than the enhancements described below to the allowance for doubtful accounts policy as a result of the adoption of Accounting Standards Update (ASU) No. 2016-13, Measurement of Credit Losses on Financial Instruments
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable and contract assets for unbilled receivables are stated at the amount owed by the customer, net of allowances for estimated doubtful accounts, discounts, returns and rebates. The Company measures the allowance for doubtful accounts using an expected credit loss model, which uses a lifetime expected loss allowance for all trade accounts receivable and contract assets. To measure the expected credit losses, trade accounts receivable and contract assets are grouped based on shared credit risk characteristics and the days past due. Contract assets relate to unbilled work in progress and have substantially the same risk characteristics as trade accounts receivable for the same types of contracts. Therefore, the Company has concluded that the expected loss rates for trade accounts receivables are a reasonable approximation of the loss rates for the contract assets. In calculating an allowance for doubtful accounts, the Company uses its historical experience, external indicators and forward-looking information to calculate expected credit losses using an aging method. The Company assesses impairment of trade accounts receivable on a collective basis as they possess shared credit risk characteristics which have been grouped based on the days past due. The expected loss rates are based on the payment profiles of sales over the preceding thirty-six months and the corresponding historical credit losses experienced within this period. The historical loss rates are adjusted to reflect current and forward-looking information on macroeconomic factors affecting the ability of the customers to settle their trade accounts receivable.
Concentrations of Risk and Related Party Transactions	Concentrations of Risk and Related Party Transactions Net sales to Comcast Corporation and affiliates (Comcast) accounted for 12% and 10% of the Company’s total net sales during the three and six months ended June 30, 2020, respectively. No other direct customer accounted for 10% or more of the Company’s total net sales. No direct customer accounted for 10% 10% The Company relies on sole suppliers or a limited group of suppliers for certain key components, subassemblies and modules and a limited group of contract manufacturers to manufacture a significant portion of its products. Any disruption or termination of these arrangements could have a material adverse impact on the Company’s results of operations. As of June 30, 2020, funds affiliated with Carlyle Partners VII S1 Holdings, L.P. (Carlyle) owned 100% of the Series A Convertible Preferred Stock (the Convertible Preferred Stock), which was issued to Carlyle to fund the Acquisition. See Note 11 for further discussion of the Convertible Preferred Stock. Other than transactions related to the Convertible Preferred Stock, there were no material related party transactions for the three or six months ended June 30, 2020.
Product Warranties	Product Warranties The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over various periods, depending upon the product subject to the warranty and the terms of the individual agreements. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material. The following table summarizes the activity in the product warranty accrual, included in accrued and other liabilities and other noncurrent liabilities: Three Months Ended Six Months Ended June 30, June 30, 2020 2019 2020 2019 Product warranty accrual, beginning of period $ 57.3 $ 14.1 $ 61.0 $ 15.6 Obligation assumed under ARRIS acquisition — 57.4 — 57.4 Provision for warranty claims 3.4 6.5 7.4 6.0 Warranty claims paid (4.9 ) (11.5 ) (12.0 ) (12.4 ) Foreign exchange 0.1 0.1 (0.5 ) — Product warranty accrual, end of period $ 55.9 $ 66.6 $ 55.9 $ 66.6
Commitments and Contingencies	Commitments and Contingencies The Company is party to certain intellectual property claims and periodically receives notices asserting that its products infringe on another party’s patents and other intellectual property rights. These claims and assertions, whether against the Company directly or against its customers, could require the Company to pay damages, royalties, stop offering the relevant products and/or cease other activities. The Company may also be called upon to indemnify certain customers for costs related to products sold to such customers. While the outcome of the claims and notices is uncertain and a reasonable estimate of the loss from unfavorable outcomes in certain of these matters cannot be determined, an adverse outcome could result in a material loss. As of June 30, 2020, the Company had a liability of $39.8 million recorded in accrued and other liabilities on the Condensed Consolidated Balance Sheets related to certain intellectual property assertions that have been settled or are in process of settlement. Of that amount, $27.1 million was attributed to periods prior to the Acquisition and was previously recorded as a liability on the opening balance sheet. For the three and six months ended June 30, 2020, $7.5 million and $12.8 million, respectively, was recorded as a charge to cost of sales in the Condensed Consolidated Statements of Operations impacting the Broadband and Home segments. One matter, making up $19.0 million of the total recorded liability, was settled in July 2020 and the settlement is payable in the second half of 2020. The Company is either a plaintiff or a defendant in certain other pending legal matters in the normal course of business. Management believes none of these other pending legal matters will have a material adverse effect on the Company’s business or financial condition upon final disposition. In addition, the Company is subject to various federal, state, local and foreign laws and regulations governing the use, discharge, disposal and remediation of hazardous materials. Compliance with current laws and regulations has not had, and is not expected to have, a materially adverse effect on the Company’s financial condition or results of operations.
Asset Impairments	Asset Impairments Goodwill is tested for impairment annually or at other times if events have occurred or circumstances exist that indicate the carrying value of the reporting unit may exceed its fair value. See Notes 3 and 8 for discussion of goodwill impairment charges during the three and six months ended June 30, 2020. There were no goodwill impairments identified during the three or six months ended June 30, 2019. Property, plant and equipment and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, based on the undiscounted cash flows expected to be derived from the use and ultimate disposition of the assets. Assets identified as impaired are adjusted to estimated fair value. Equity investments without readily determinable fair values are evaluated each reporting period for impairment based on a qualitative assessment and are then measured at fair value if an impairment is determined to exist. Other than certain assets impaired as a result of restructuring actions, there were no definite-lived intangible or other long-lived asset impairments identified during the three or six months ended June 30, 2020 or 2019.
Income Taxes	Income Taxes For the three and six months ended June 30, 2020, the Company’s effective tax rate was 4.5% and 8.8%, respectively, and the Company recognized a tax benefit of $15.1 million on a pretax loss of $336.2 million and $46.5 million on a pretax loss of $527.5 million, respectively. The Company’s tax benefit was less than the statutory rate of 21.0% in both the three and six months ended June 30, 2020 primarily due to a goodwill impairment charge of $206.7 million for which minimal tax benefits were recorded and $20.3 million and $21.9 million, respectively, of tax expense related to state valuation allowances. Excess tax costs of $3.7 million and $7.8 million related to equity compensation awards also impacted the tax benefit unfavorably for the three and six months ended June 30, 2020, respectively. For the three and six months ended June 30, 2019, the Company’s effective income tax rate was 10.1% and 9.6%, respectively, and the Company recognized a tax benefit of $37.5 million on a pretax loss of $371.5 million and a tax benefit of $35.9 million on a pretax loss of $372.2 million, respectively. The Company’s tax benefit was unfavorably impacted by the impact of U.S. anti-deferral provisions and foreign withholding taxes, but this impact was partially offset by the favorable impact of federal tax credits for the three and six months ended June 30, 2019. The impact of excess tax costs related to equity-based compensation awards was not material for the three and six months ended June 30, 2019.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share (EPS) is computed by dividing net income (loss), less any dividends and deemed dividends related to the Convertible Preferred Stock, by the weighted average number of common shares outstanding during the period. The numerator in diluted EPS is based on the basic EPS numerator adjusted to add back any dividends and deemed dividends related to the Convertible Preferred Stock, subject to antidilution requirements. The denominator used in diluted EPS is based on the basic EPS computation plus the effect of potentially dilutive common shares related to the Convertible Preferred Stock and equity-based compensation plans, subject to antidilution requirements. For the three and six months ended June 30, 2020, 17.0 million and 16.6 million shares, respectively, of outstanding equity-based compensation awards were not included in the computation of diluted EPS because the effect was either antidilutive or the performance conditions were not met. Of those amounts, for the three and six months ended June 30, 2020, 4.3 million and 4.4 million shares, respectively, would have been considered dilutive if the Company had not been in a net loss position. For the three and six months ended June 30, 2019, 12.2 million shares and 8.9 million shares, respectively, were not included in the computation of diluted EPS because the effect was either antidilutive or the performance conditions were not met. Of those amounts, for the three and six months ended June 30, 2019, 2.2 million shares and 2.5 million shares, respectively, would have been considered dilutive if the Company had not been in a net loss position. For the three and six months ended June 30, 2020, 36.9 million and 36.6 million, respectively, of as-if converted shares related to the Convertible Preferred Stock were excluded from the diluted share count because they were anti-dilutive; however, they would have been considered dilutive if the Company had not been in a net loss position.

Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted During the Six Months Ended June 30, 2020 On January 1, 2020, the Company adopted ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance: ASU No. 2018-19, ASU No. 2019-04, ASU No. 2019-05 and ASU No. 2020-02 (collectively, Topic 326) the incurred loss methodology with the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including trade accounts receivable. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842. The Company adopted Topic 326 using the modified retrospective method for all financial assets measured at amortized cost, which are primarily trade accounts receivable and contract assets for the Company. Results for reporting periods beginning after January 1, 2020 are presented under Topic 326 while prior period amounts continue to be reported in accordance with previously applicable U.S. GAAP. The impact of adopting Topic 326 as of January 1, 2020 was not material to the consolidated financial statements. Issued but Not Adopted In March 2020, the Financial Accounting Standards Board (FASB) issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to transactions affected by reference rate reform if certain criteria are met. These transactions include contract modifications, hedging relationships, and sale or transfer of debt securities classified as held-to-maturity. The Company can elect to apply the amendments as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this guidance on the consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01 , Investments - Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The new guidance is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. T he amendments in this guidance clarify the interaction of accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. ASU No. 2020-01 is effective for the Company as of January 1, 202 1 and e arly adoption is permitted. The Company is evaluating the impact of the new guidance on the consolidated financial statements. In December 2019 the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes .
