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 the core, access and edge layers of communication networks. The Company’s solutions and services for wired and wireless networks enable high-bandwidth data, video and voice applications. 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. Basis of Presentation The Condensed Consolidated Balance Sheet as of June 30, 2018, the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2018 and 2017, and the Condensed Consolidated Statements of Cash Flows and Stockholders’ Equity for the six months ended June 30, 2018 and 2017 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. 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 Company’s Annual Report on Form 10-K for the year ended December 31, 2017 (the 2017 Annual Report). Other than the changes described below to revenue recognition policies as a result of the adoption of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, Revenue Recognition The Company recognizes revenue based on the satisfaction of distinct obligations to transfer goods and services to customers. The majority of the Company’s revenue is from product sales. Revenue from product sales is recognized when control is transferred to the customer, typically upon either shipment or delivery. A minor portion of the Company’s revenue is derived from project contracts containing a combination of product and service obligations. Revenue from project contracts is recognized either at a point in time or over time using cost input methods, based on the specific terms of each contract. For project contracts containing multiple distinct performance obligations, the transaction price is allocated based on the relative standalone estimated selling price of each performance obligation. The relative standalone selling price is determined using current price lists and observable pricing in separate contracts with similar customers. For performance obligations recognized over-time, judgment is required to evaluate assumptions, including the total estimated costs to determine progress towards completion of the performance obligation and to calculate the corresponding amount of revenue to recognize. If estimated total costs on any contract are greater than the net contract revenues, the entire estimated loss is recognized in the period the loss becomes known. The cumulative effects on revenue from revisions to total estimated costs are recorded in the period in which the revisions to estimates are identified and the amounts can be reasonably estimated. The Company also recognizes revenue from other customer contract types, including licensing of intellectual property, software licensing and post-contract support (PCS) which may be sold as part of a bundled product offering or as a separate contract. For bundled product arrangements, the transaction price is allocated based on the relative standalone estimated selling price of each performance obligation. Distinct intellectual property obligations, including software, are considered functional in nature and are recognized as revenue at the point in time the customer receives the rights to use and benefit from the intellectual property or are determined using a usage-based royalty. PCS obligations are typically recognized over the term of the contract. Revenue is measured based on the consideration to which the Company expects to be entitled, based on customer contracts. For sales to distributors, system integrators and value-added resellers (primarily for the CommScope Connectivity Solutions (CCS) segment), revenue is adjusted for variable consideration amounts, including estimated discounts, returns, rebates and distributor price protection programs. These estimates are determined based upon historical experience, contract terms, inventory levels in the distributor channel and other related factors. Adjustments to variable consideration estimates are recorded when circumstances indicate revisions may be necessary. The Company records a contract asset for unbilled accounts receivable related to revenue that has been recognized in advance of consideration being unconditionally due from the customer, which is common for certain project contract performance obligations. Contract asset amounts are transferred to accounts receivable when the Company’s right to the consideration becomes unconditional, which varies by contract, but is generally based on achieving certain acceptance milestones. A contract liability for deferred revenue is recorded when consideration is received or is unconditionally due from a customer prior to transferring control of goods or services to the customer under the terms of a contract. Deferred revenue balances typically result from advance payments received from customers for product contracts or from billings in excess of revenue recognized on project or services arrangements. Concentrations of Risk and Related Party Transactions Net sales to Anixter International Inc. and its affiliates (Anixter) accounted for 11% of the Company’s total net sales during both the three and six months ended June 30, 2018. Net sales to Anixter accounted for 12% and 11% of the Company’s total net sales during the three and six months ended June 30, 2017, respectively. Sales to Anixter primarily originate within the CCS segment. Net sales to KGP Companies (KGPCo) accounted for 10% of the Company’s net sales during the three months ended June 30, 2018 but did not exceed 10% for the six months ended June 30, 2018 or the three or six months ended June 30, 2017. KGPCo provides supply chain management to operators deploying wired and wireless networks in the United States (U.S.) and services end-users of both of the Company’s segments. Other than Anixter and KGPCo, no direct customer accounted for 10% or more of the Company’s total net sales for the three or six months ended June 30, 2018 or 2017. Accounts receivable from Anixter accounted for 10% of the Company’s accounts receivable as of June 30, 2018. Other than Anixter, no direct customer accounted for 10% or more of the Company’s accounts receivable as of June 30, 2018. 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 periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. 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 other accrued liabilities: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Product warranty accrual, beginning of period $ 16,150 $ 20,180 $ 16,928 $ 21,631 Provision for warranty claims 458 2,028 1,878 4,231 Warranty claims paid (1,697 ) (2,029 ) (3,913 ) (5,718 ) Foreign exchange (65 ) 104 (47 ) 139 Product warranty accrual, end of period $ 14,846 $ 20,283 $ 14,846 $ 20,283 Commitments and Contingencies The Company is either a plaintiff or a defendant in certain pending legal matters in the normal course of business. The Company may also be called upon to indemnify certain customers for costs related to products or services sold to such customers. Management believes none of these 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. There were no goodwill impairments identified during the three or six months ended June 30, 2018 or 2017. 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 carried at 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, 2018 or 2017. Income Taxes On December 22, 2017, the U.S. government enacted tax reform legislation that reduced the corporate income tax rate from 35% to 21% and included a broad range of complex provisions affecting the taxation of businesses. Generally, financial statement recognition of the new legislation would be required to be completed in the period of enactment; however, in response to the complexities of this new legislation, the Securities and Exchange Commission (SEC) staff issued Staff Accounting Bulletin No. 118 to provide companies with transitional relief. Specifically, when the initial accounting for items under the new legislation is incomplete, the guidance allows the recognition of provisional amounts when reasonable estimates can be made or the continued application of the prior tax law if a reasonable estimate of the effect cannot be made. The SEC staff has provided up to one year from the date of enactment for companies to finalize the accounting for the effects of this new legislation. Although no changes were made to the provisional amounts during the three months or six months ended June 30, 2018, the Company expects to refine the calculations as additional analysis is completed and as a more thorough understanding of the new tax law is reached. The changes made could be material to income tax expense. The effective income tax rate of 36.0% and 33.2% for the three and six months ended June 30, 2018, respectively, was higher than the statutory rate of 21.0% primarily due to the effect of the provision for state income taxes, the impact of earnings in foreign jurisdictions that are taxed at rates higher than the U.S. statutory rate, the impact of the new U.S. anti-deferral provisions and the impact of repatriation taxes. These increases to the effective tax rate were partially offset by the favorable impact of $0.4 million and $4.7 million of excess tax benefits related to equity-based compensation awards for the three and six months ended June 30, 2018, respectively. The effective income tax rate of 30.3% and 22.9% for the three and six months ended June 30, 2017, respectively, was lower than the statutory rate of 35.0% primarily due to the favorable impact of $4.4 million and $13.1 million of excess tax benefits related to equity-based compensation awards for the three and six months ended June 30, 2017, respectively. The effective income tax rate was also favorably affected by the impact of earnings in foreign jurisdictions that the Company did not plan to repatriate. These earnings were generally taxed at rates lower than the U.S. statutory rate. Offsetting these decreases for the three and six months ended June 30, 2017 was the effect of the provision for state income taxes. Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on net income divided by the weighted average number of common shares outstanding plus the effect of potentially dilutive common shares using the treasury stock method. Potentially dilutive common shares include outstanding equity-based awards (stock options, restricted stock units and performance share units). Certain outstanding equity-based awards were not included in the computation of diluted earnings per share because the effect was either antidilutive or the performance conditions were not met (2.2 million shares and 1.7 million shares for the three and six months ended June 30, 2018, respectively, and 0.7 million shares and 0.5 million shares for the three and six months ended June 30, 2017, respectively). The following table presents the basis for the earnings per share computations (in thousands, except per share data): Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Numerator: Net income for basic and diluted earnings per share $ 65,922 $ 55,464 $ 99,657 $ 89,026 Denominator: Weighted average common shares outstanding - basic 192,162 193,092 191,767 193,555 Dilutive effect of equity-based awards 3,024 4,126 3,579 4,618 Weighted average common shares outstanding - diluted 195,186 197,218 195,346 198,173 Earnings per share: Basic $ 0.34 $ 0.29 $ 0.52 $ 0.46 Diluted $ 0.34 $ 0.28 $ 0.51 $ 0.45 Recent Accounting Pronouncements Adopted During the Six Months Ended June 30, 2018 The Company adopted ASU No. 2014-09, Revenue from Contracts with Customers, Revenue recognition for the Company’s product sales remained generally consistent with historical practice. However, the adoption of ASU No. 2014-09 resulted in acceleration of revenue recognition for certain project contracts containing integrated product and service obligations, primarily within the CommScope Mobility Solutions (CMS) segment. These multi-element contracts represented less than 2.0% of total net sales for the three and six months ended June 30, 2018 and 2017. For these contracts, certain performance obligations are recognized over time using cost-based input methods, which recognize revenue and cost of sales based on the relationship between actual costs incurred compared to the total estimated cost for the performance obligation.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	6. DERIVATIVES AND HEDGING ACTIVITIES Derivatives Not Designated As Hedging Instruments The Company uses forward contracts to hedge a portion of its balance sheet foreign exchange re-measurement risk and to hedge certain planned foreign currency expenditures. As of June 30, 2018, the Company had foreign exchange contracts outstanding with maturities of up to fourteen months and aggregate notional values of $421 million (based on exchange rates as of June 30, 2018). Unrealized gains and losses resulting from these contracts are recognized in other income (expense), net and partially offset corresponding foreign exchange gains and losses on the balances and expenditures being hedged. These instruments are not held for speculative or trading purposes, are not designated as hedges for hedge accounting purposes and are marked to market each period through earnings. The following table presents the balance sheet location and fair value of the Company’s derivatives not designated as hedging instruments: Fair Value of Asset (Liability) Balance Sheet Location June 30, 2018 December 31, 2017 Foreign currency contracts Prepaid expenses and other current assets $ 1,908 $ 9,050 Foreign currency contracts Other accrued liabilities (5,037 ) (574 ) Foreign currency contracts Other noncurrent liabilities (309 ) — Total derivatives not designated as hedging instruments $ (3,438 ) $ 8,476 The pretax impact of these foreign currency forward contracts, both matured and outstanding, on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) is as follows: Foreign Currency Forward Contracts Location of Gain (Loss) Gain (Loss) Recognized Three Months Ended June 30, 2018 Other income (expense), net $ (19,441 ) Three Months Ended June 30, 2017 Other income (expense), net $ 12,553 Six Months Ended June 30, 2018 Other income (expense), net $ (7,561 ) Six Months Ended June 30, 2017 Other income (expense), net $ 14,409 Derivative Instruments Designated As Net Investment Hedge The Company has a hedging strategy to designate certain foreign exchange contracts as net investment hedges to mitigate a portion of the foreign currency risk on the euro net investment in a foreign subsidiary. As of June 30, 2018, the Company held designated forward contracts with outstanding maturities of up to six months and an aggregate notional value of $55.0 million. In the first quarter of 2018, the Company changed the method used to assess the effectiveness of its net investment hedges from the forward rate method to the spot rate method. The Company believes the spot rate method better aligns with the underlying foreign currency exposure of the hedged net investment. Effective January 1, 2018, the spot-forward differences of the designated forward contracts are excluded from hedge effectiveness at inception and are recognized on a straight-line basis to other income (expense), net over the life of each contract. The amortization of the spot-forward differences was not material for the three or six months ended June 30, 2018. Hedge effectiveness is assessed each quarter based on the net investment in the foreign subsidiary designated as the hedged item and the changes in the fair value of designated forward contracts based on spot rates. For hedges that meet the effectiveness requirements, changes in fair value are recorded as a component of other comprehensive income (loss), net of tax. As of June 30, 2018, there was no ineffectiveness on the instruments designated as net investment hedges. The following table presents the balance sheet location and fair value of the derivative instruments designated as net investment hedges: Fair Value of Asset (Liability) Balance Sheet Location June 30, 2018 December 31, 2017 Foreign currency contracts Prepaid expenses and other current assets $ 2,319 $ — Foreign currency contracts Other accrued liabilities — (403 ) Total derivatives designated as net investment hedging instruments $ 2,319 $ (403 ) The after-tax impact of the effective portion of the forward contracts designated as net investment hedging instruments, both matured and outstanding, on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) is as follows: Foreign Currency Forward Contracts Location of Gain (Loss) Effective Portion of Gain (Loss) Recognized Three Months Ended June 30, 2018 Other comprehensive income (loss), net of tax $ 3,051 Three Months Ended June 30, 2017 Other comprehensive income (loss), net of tax $ (2,996 ) Six Months Ended June 30, 2018 Other comprehensive income (loss), net of tax $ 2,453 Six Months Ended June 30, 2017 Other comprehensive income (loss), net of tax $ (3,351 )

Restructuring And Related Activities [Abstract]
Restructuring Costs	9. 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 composed of employee-related costs, lease termination costs and fixed asset related costs. Employee-related costs include the expected severance costs and related benefits as well as one-time severance benefits that are accrued over the remaining period employees are required to work in order to receive such benefits. Lease termination costs include the discounted cost of unused leased facilities, net of anticipated sub-rental income. Fixed asset related costs include non-cash impairments or fixed asset disposals associated with restructuring actions in addition to the cash costs to uninstall, pack, ship and reinstall manufacturing equipment and the costs to prepare the receiving facility to accommodate relocated equipment. Fixed asset related costs are expensed as incurred. Cash paid is net of proceeds received from the sale of related assets. As a result of restructuring and consolidation actions, the Company owns unutilized real estate at various facilities in the U.S. and internationally. The Company is attempting to sell or lease this unutilized space. Additional impairment charges may be incurred related to these or other excess assets. The Company’s net pretax restructuring charges, by segment, were as follows: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 CCS $ 4,687 $ 9,596 $ 7,058 $ 14,352 CMS 2,531 4,177 5,610 4,809 Total $ 7,218 $ 13,773 $ 12,668 $ 19,161 Restructuring reserves were included in the Company’s Condensed Consolidated Balance Sheets as follows: June 30, 2018 December 31, 2017 Other accrued liabilities $ 14,211 $ 24,961 Other noncurrent liabilities 5,399 7,036 Total liability $ 19,610 $ 31,997 Cost Alignment Restructuring Actions Prior to the acquisition of TE Connectivity’s Broadband Network Solutions (BNS) business in August 2015, the Company initiated restructuring actions to realign and lower its cost structure, primarily through workforce reductions and other cost reduction initiatives, including the cessation of manufacturing operations at various facilities. As of June 30, 2018, these actions were substantially complete except for a $4.4 million liability for lease termination costs, for which the Company expects to make cash payments of $0.9 million during the remainder of 2018 and make the remaining payments of $3.5 million between 2019 and 2022. BNS Integration Restructuring Actions Following the acquisition of BNS, 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 BNS integration restructuring actions was as follows: Employee- Related Costs Lease Termination Costs Fixed Asset Related Costs Total Balance at March 31, 2018 $ 16,097 $ 904 $ — $ 17,001 Additional charge recorded 7,092 151 (83 ) 7,160 Cash paid (8,131 ) (378 ) (248 ) (8,757 ) Consideration received — — 2,235 2,235 Foreign exchange and other non-cash items (503 ) (25 ) (1,904 ) (2,432 ) Balance at June 30, 2018 $ 14,555 $ 652 $ — $ 15,207 Balance at December 31, 2017 $ 25,588 $ 1,080 $ — $ 26,668 Additional charge recorded 11,030 809 708 12,547 Cash paid (21,823 ) (1,222 ) (395 ) (23,440 ) Consideration received — — 4,514 4,514 Foreign exchange and other non-cash items (240 ) (15 ) (4,827 ) (5,082 ) Balance at June 30, 2018 $ 14,555 $ 652 $ — $ 15,207 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 $122.2 million since the BNS acquisition for integration actions. No significant additional restructuring charges are expected to be incurred to complete the previously announced BNS integration initiatives. The Company expects to make cash payments of $10.2 million during the remainder of 2018 and additional cash payments of $5.0 million between 2019 and 2022. Future restructuring actions may be identified and the resulting charges and cash requirements may be material.

The Company contributed $4.6 million and $5.7 million to its defined benefit pension plans during the three and six months ended June 30, 2018, respectively. During the remainder of 2018, the Company anticipates making additional contributions of approximately $3.4 million to these plans. During the first quarter of 2018, the Company communicated its intent to terminate a significant U.S. defined benefit pension plan. The Company contributed $3.0 million to the plan during the three and six months ended June 30, 2018, which was needed to substantially fund the termination of the plan, which will be effected through the purchase of annuities. This contribution is included in the contributed amounts discussed above. Upon termination, which is expected in late 2018 or early 2019, the Company expects to recognize a pretax charge in other income (expense), net, primarily related to unrecognized net actuarial losses currently recorded in accumulated other comprehensive loss of $27 million to $29 million. Other Postretirement Benefit Plans The Company has amended certain of its U.S. postretirement medical plans to terminate benefits as of December 31, 2018. The Company expects to recognize a pretax gain in other income (expense), net, in the fourth quarter of 2018 related to unrecognized prior service credits and unrecognized net actuarial gains currently recorded in accumulated other comprehensive loss of $9 million to $10 million.

Equity [Abstract]
Stockholders' Equity	11. STOCKHOLDERS’ EQUITY Stock Repurchase Program On August 3, 2017, the Company announced its Board of Directors had authorized the repurchase of up to $100.0 million of the Company’s outstanding common stock. No shares were repurchased under this plan during the three or six months ended June 30, 2018. The remaining authorization under the plan was $25.0 million at June 30, 2018 and expires on July 31, 2018. Equity-Based Compensation Plans As of June 30, 2018, $80.9 million of unrecognized compensation costs related to unvested stock options, restricted stock units (RSUs) and performance share units (PSUs) are 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, 2018. The following table shows the location of equity-based compensation expense on the statement of operations: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Selling, general and administrative $ 9,023 $ 8,517 $ 17,063 $ 15,676 Cost of sales 1,501 1,418 2,833 2,615 Research and development 1,324 1,251 2,500 2,307 Total equity-based compensation expense $ 11,848 $ 11,186 $ 22,396 $ 20,598 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 generally vest over three years following the grant date and have a contractual term of ten years. The following table summarizes the stock option activity (in thousands, 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, 2018 4,901 $ 15.21 Granted 33 $ 39.46 Exercised (102 ) $ 9.70 Forfeited (48 ) $ 34.73 Options outstanding at June 30, 2018 4,784 $ 15.30 4.3 $ 75,053 Options outstanding at December 31, 2017 4,830 $ 13.01 Granted 477 $ 38.42 Exercised (432 ) $ 11.37 Forfeited (91 ) $ 33.60 Options outstanding at June 30, 2018 4,784 $ 15.30 4.3 $ 75,053 Options vested at June 30, 2018 3,957 $ 10.80 3.3 $ 74,702 Options unvested at June 30, 2018 827 $ 36.80 9.1 $ 351 The exercise prices of outstanding options at June 30, 2018 were in the following ranges (in thousands, 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 2,502 2.4 $ 5.42 2,502 $ 5.42 $5.75 to $22.99 653 1.9 $ 8.58 653 $ 8.58 $23.00 to $42.32 1,629 8.1 $ 33.16 802 $ 29.40 $2.96 to $42.32 4,784 4.3 $ 15.30 3,957 $ 10.80 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. 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, 2018 and 2017. Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Expected option term (in years) 6.0 6.0 6.0 6.0 Risk-free interest rate 2.6% 2.0% 2.7 % 2.0 % Expected volatility 35.0% 40.0% 35.0 % 40.0 % Weighted average exercise price $ 39.46 $ 42.32 $ 38.42 $ 38.00 Weighted average fair value at grant date $ 15.19 $ 17.48 $ 14.86 $ 15.72 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 thousands, except per share data): Restricted Stock Units Weighted Average Grant Date Fair Value Per Share Non-vested RSUs at March 31, 2018 2,217 $ 35.51 Granted 54 $ 30.77 Vested and shares issued (36 ) $ 35.02 Forfeited (80 ) $ 34.64 Non-vested RSUs at June 30, 2018 2,155 $ 35.43 Non-vested RSUs at December 31, 2017 2,279 $ 31.83 Granted 1,120 $ 37.98 Vested and shares issued (1,073 ) $ 30.77 Forfeited (171 ) $ 33.35 Non-vested RSUs at June 30, 2018 2,155 $ 35.43 Performance Share Units PSUs are stock 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 thousands, except per share data): Performance Share Units Weighted Average Grant Date Fair Value Per Share Non-vested PSUs at March 31, 2018 300 $ 33.45 Granted 13 $ 39.46 Vested and shares issued (1 ) $ 27.64 Forfeited (18 ) $ 28.01 Non-vested PSUs at June 30, 2018 294 $ 34.07 Non-vested PSUs at December 31, 2017 344 $ 26.75 Granted 184 $ 38.42 Vested and shares issued (203 ) $ 26.80 Forfeited (31 ) $ 26.27 Non-vested PSUs at June 30, 2018 294 $ 34.07

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Condensed Consolidated Balance Sheet as of June 30, 2018, the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2018 and 2017, and the Condensed Consolidated Statements of Cash Flows and Stockholders’ Equity for the six months ended June 30, 2018 and 2017 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. 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 Company’s Annual Report on Form 10-K for the year ended December 31, 2017 (the 2017 Annual Report). Other than the changes described below to revenue recognition policies as a result of the adoption of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers,
Revenue Recognition	Revenue Recognition The Company recognizes revenue based on the satisfaction of distinct obligations to transfer goods and services to customers. The majority of the Company’s revenue is from product sales. Revenue from product sales is recognized when control is transferred to the customer, typically upon either shipment or delivery. A minor portion of the Company’s revenue is derived from project contracts containing a combination of product and service obligations. Revenue from project contracts is recognized either at a point in time or over time using cost input methods, based on the specific terms of each contract. For project contracts containing multiple distinct performance obligations, the transaction price is allocated based on the relative standalone estimated selling price of each performance obligation. The relative standalone selling price is determined using current price lists and observable pricing in separate contracts with similar customers. For performance obligations recognized over-time, judgment is required to evaluate assumptions, including the total estimated costs to determine progress towards completion of the performance obligation and to calculate the corresponding amount of revenue to recognize. If estimated total costs on any contract are greater than the net contract revenues, the entire estimated loss is recognized in the period the loss becomes known. The cumulative effects on revenue from revisions to total estimated costs are recorded in the period in which the revisions to estimates are identified and the amounts can be reasonably estimated. The Company also recognizes revenue from other customer contract types, including licensing of intellectual property, software licensing and post-contract support (PCS) which may be sold as part of a bundled product offering or as a separate contract. For bundled product arrangements, the transaction price is allocated based on the relative standalone estimated selling price of each performance obligation. Distinct intellectual property obligations, including software, are considered functional in nature and are recognized as revenue at the point in time the customer receives the rights to use and benefit from the intellectual property or are determined using a usage-based royalty. PCS obligations are typically recognized over the term of the contract. Revenue is measured based on the consideration to which the Company expects to be entitled, based on customer contracts. For sales to distributors, system integrators and value-added resellers (primarily for the CommScope Connectivity Solutions (CCS) segment), revenue is adjusted for variable consideration amounts, including estimated discounts, returns, rebates and distributor price protection programs. These estimates are determined based upon historical experience, contract terms, inventory levels in the distributor channel and other related factors. Adjustments to variable consideration estimates are recorded when circumstances indicate revisions may be necessary. The Company records a contract asset for unbilled accounts receivable related to revenue that has been recognized in advance of consideration being unconditionally due from the customer, which is common for certain project contract performance obligations. Contract asset amounts are transferred to accounts receivable when the Company’s right to the consideration becomes unconditional, which varies by contract, but is generally based on achieving certain acceptance milestones. A contract liability for deferred revenue is recorded when consideration is received or is unconditionally due from a customer prior to transferring control of goods or services to the customer under the terms of a contract. Deferred revenue balances typically result from advance payments received from customers for product contracts or from billings in excess of revenue recognized on project or services arrangements.
Concentrations of Risk and Related Party Transactions	Concentrations of Risk and Related Party Transactions Net sales to Anixter International Inc. and its affiliates (Anixter) accounted for 11% of the Company’s total net sales during both the three and six months ended June 30, 2018. Net sales to Anixter accounted for 12% and 11% of the Company’s total net sales during the three and six months ended June 30, 2017, respectively. Sales to Anixter primarily originate within the CCS segment. Net sales to KGP Companies (KGPCo) accounted for 10% of the Company’s net sales during the three months ended June 30, 2018 but did not exceed 10% for the six months ended June 30, 2018 or the three or six months ended June 30, 2017. KGPCo provides supply chain management to operators deploying wired and wireless networks in the United States (U.S.) and services end-users of both of the Company’s segments. Other than Anixter and KGPCo, no direct customer accounted for 10% or more of the Company’s total net sales for the three or six months ended June 30, 2018 or 2017. Accounts receivable from Anixter accounted for 10% of the Company’s accounts receivable as of June 30, 2018. Other than Anixter, no direct customer accounted for 10% or more of the Company’s accounts receivable as of June 30, 2018.
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 periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. 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 other accrued liabilities: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Product warranty accrual, beginning of period $ 16,150 $ 20,180 $ 16,928 $ 21,631 Provision for warranty claims 458 2,028 1,878 4,231 Warranty claims paid (1,697 ) (2,029 ) (3,913 ) (5,718 ) Foreign exchange (65 ) 104 (47 ) 139 Product warranty accrual, end of period $ 14,846 $ 20,283 $ 14,846 $ 20,283
Commitments and Contingencies	Commitments and Contingencies The Company is either a plaintiff or a defendant in certain pending legal matters in the normal course of business. The Company may also be called upon to indemnify certain customers for costs related to products or services sold to such customers. Management believes none of these 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. There were no goodwill impairments identified during the three or six months ended June 30, 2018 or 2017. 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 carried at 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, 2018 or 2017.
Income Taxes	Income Taxes On December 22, 2017, the U.S. government enacted tax reform legislation that reduced the corporate income tax rate from 35% to 21% and included a broad range of complex provisions affecting the taxation of businesses. Generally, financial statement recognition of the new legislation would be required to be completed in the period of enactment; however, in response to the complexities of this new legislation, the Securities and Exchange Commission (SEC) staff issued Staff Accounting Bulletin No. 118 to provide companies with transitional relief. Specifically, when the initial accounting for items under the new legislation is incomplete, the guidance allows the recognition of provisional amounts when reasonable estimates can be made or the continued application of the prior tax law if a reasonable estimate of the effect cannot be made. The SEC staff has provided up to one year from the date of enactment for companies to finalize the accounting for the effects of this new legislation. Although no changes were made to the provisional amounts during the three months or six months ended June 30, 2018, the Company expects to refine the calculations as additional analysis is completed and as a more thorough understanding of the new tax law is reached. The changes made could be material to income tax expense. The effective income tax rate of 36.0% and 33.2% for the three and six months ended June 30, 2018, respectively, was higher than the statutory rate of 21.0% primarily due to the effect of the provision for state income taxes, the impact of earnings in foreign jurisdictions that are taxed at rates higher than the U.S. statutory rate, the impact of the new U.S. anti-deferral provisions and the impact of repatriation taxes. These increases to the effective tax rate were partially offset by the favorable impact of $0.4 million and $4.7 million of excess tax benefits related to equity-based compensation awards for the three and six months ended June 30, 2018, respectively. The effective income tax rate of 30.3% and 22.9% for the three and six months ended June 30, 2017, respectively, was lower than the statutory rate of 35.0% primarily due to the favorable impact of $4.4 million and $13.1 million of excess tax benefits related to equity-based compensation awards for the three and six months ended June 30, 2017, respectively. The effective income tax rate was also favorably affected by the impact of earnings in foreign jurisdictions that the Company did not plan to repatriate. These earnings were generally taxed at rates lower than the U.S. statutory rate. Offsetting these decreases for the three and six months ended June 30, 2017 was the effect of the provision for state income taxes.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on net income divided by the weighted average number of common shares outstanding plus the effect of potentially dilutive common shares using the treasury stock method. Potentially dilutive common shares include outstanding equity-based awards (stock options, restricted stock units and performance share units). Certain outstanding equity-based awards were not included in the computation of diluted earnings per share because the effect was either antidilutive or the performance conditions were not met (2.2 million shares and 1.7 million shares for the three and six months ended June 30, 2018, respectively, and 0.7 million shares and 0.5 million shares for the three and six months ended June 30, 2017, respectively). The following table presents the basis for the earnings per share computations (in thousands, except per share data): Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Numerator: Net income for basic and diluted earnings per share $ 65,922 $ 55,464 $ 99,657 $ 89,026 Denominator: Weighted average common shares outstanding - basic 192,162 193,092 191,767 193,555 Dilutive effect of equity-based awards 3,024 4,126 3,579 4,618 Weighted average common shares outstanding - diluted 195,186 197,218 195,346 198,173 Earnings per share: Basic $ 0.34 $ 0.29 $ 0.52 $ 0.46 Diluted $ 0.34 $ 0.28 $ 0.51 $ 0.45
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted During the Six Months Ended June 30, 2018 The Company adopted ASU No. 2014-09, Revenue from Contracts with Customers, Revenue recognition for the Company’s product sales remained generally consistent with historical practice. However, the adoption of ASU No. 2014-09 resulted in acceleration of revenue recognition for certain project contracts containing integrated product and service obligations, primarily within the CommScope Mobility Solutions (CMS) segment. These multi-element contracts represented less than 2.0% of total net sales for the three and six months ended June 30, 2018 and 2017. For these contracts, certain performance obligations are recognized over time using cost-based input methods, which recognize revenue and cost of sales based on the relationship between actual costs incurred compared to the total estimated cost for the performance obligation. Based on contracts in effect at January 1, 2018, the Company recorded a cumulative effect adjustment, net of tax, of $3.4 million, which reduced the accumulated deficit on the Condensed Consolidated Balance Sheets. This adjustment reflects an acceleration of revenues of $8.0 million. The impact of adoption of the new revenue recognition standard on our condensed consolidated financial statements was as follows: Three Months Ended June 30, 2018 Six Months Ended June 30, 2018 As Reported Amounts Without Adoption of ASU No. 2014-09 Effect of Change Increase / (Decrease) As Reported Amounts Without Adoption of ASU No. 2014-09 Effect of Change Increase / (Decrease) Net sales $ 1,239,856 $ 1,239,800 $ 56 $ 2,360,373 $ 2,362,057 $ (1,684 ) Cost of sales 768,546 768,288 258 1,477,663 1,477,185 478 Operating income 164,688 164,890 (202 ) 268,414 270,576 (2,162 ) Income tax expense 37,003 37,028 (25 ) 49,604 50,142 (538 ) Net income 65,922 66,099 (177 ) 99,657 101,281 (1,624 ) As of June 30, 2018 As Reported Amounts Without Adoption of ASU No. 2014-09 Effect of Change Increase / (Decrease) Assets: Accounts receivable, less allowance for doubtful accounts $ 1,023,716 $ 1,020,404 $ 3,312 Inventories, net 479,468 483,275 (3,807 ) Liabilities: Other accrued liabilities 297,755 300,040 (2,285 ) Equity: Retained earnings (accumulated deficit) (290,337 ) (292,127 ) 1,790 The Company adopted ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (except those accounted for under the equity method of accounting) The Company adopted ASU No. 2016-16, Accounting for Income Taxes, Intra-Entity Asset Transfers of Assets Other than Inventory, The Company adopted ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost The Company adopted ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities Issued but Not Adopted In February 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test of Goodwill Impairment In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments In February 2016, the FASB issued ASU No. 2016-02, Leases supersedes the current leasing guidance in Topic 840, Leases.
