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 September 30, 2017, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2017 and 2016, and the Condensed Consolidated Statements of Cash Flows and Stockholders’ Equity for the nine months ended September 30, 2017 and 2016 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. 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, 2016 (the 2016 Annual Report). There were no changes in the Company’s significant accounting policies during the three or nine months ended September 30, 2017. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements. Prior to January 1, 2017, the Company consolidated the operating results of the acquired BNS business based on the BNS fiscal reporting calendar that resulted in a reporting lag of one day for the year ended December 31, 2016. The BNS business results included thirteen weeks for the three months ended September 30, 2017 compared to fourteen weeks for the comparable period in 2016. Effective January 1, 2017, the reporting lag was eliminated as a result of system conversions that were part of the BNS integration. The elimination of the reporting lag represents a change in accounting principle which the Company believes to be preferable because it provides more current information to the users of its financial statements. The Company determined that it was impracticable to apply the effects of the lag elimination to financial reporting periods prior to January 1, 2017. The cumulative effect of not retroactively applying this change in accounting, however, was immaterial as of January 1, 2017. Therefore, the Company reported the cumulative effect of the change in accounting principle in net income for the nine months ended September 30, 2017 and did not retrospectively apply the effects of this change to prior periods. Concentrations of Risk and Related Party Transactions Net sales to Anixter International Inc. and its affiliates (Anixter) accounted for 12% and 11% of the Company’s total net sales during the three and nine months ended September 30, 2017, respectively. Net sales to Anixter accounted for 11% of the Company’s total net sales during the three and nine months ended September 30, 2016. Sales to Anixter primarily originate within the CommScope Connectivity Solutions (CCS) segment. Other than Anixter, no direct customer accounted for 10% or more of the Company’s total net sales for the three or nine months ended September 30, 2017 or 2016. Accounts receivable from Anixter and Verizon Communications Inc. (Verizon) each represented approximately 11% of accounts receivable as of September 30, 2017. Other than Anixter and Verizon, no direct customer accounted for 10% or more of the Company’s accounts receivable as of September 30, 2017. 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 Nine Months Ended September 30, September 30, 2017 2016 2017 2016 Product warranty accrual, beginning of period $ 20,283 $ 18,356 $ 21,631 $ 17,964 Provision for warranty claims 284 3,435 4,515 7,954 Warranty claims paid (2,033 ) (106 ) (7,751 ) (4,517 ) Foreign exchange (62 ) 92 77 376 Product warranty accrual, end of period $ 18,472 $ 21,777 $ 18,472 $ 21,777 Commitments and Contingencies The Company is either a plaintiff or a defendant in certain pending legal matters in the normal course of business. 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 and nine months ended September 30, 2017. During the nine months ended September 30, 2016, the Company recorded a $15.3 million goodwill impairment charge as a result of the change in its reportable segments. The impairment was recorded in the CCS segment. 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. During the three months and nine months ended September 30, 2016, as a result of revisions to the business plan for a particular product line, the Company determined that certain intangible assets in the CCS segment were no longer recoverable and a $7.4 million impairment charge was recorded. There were no asset impairments identified during the three and nine months ended September 30, 2017. Income Taxes The effective income tax rate of 24.8% and 23.6% for the three and nine months ended September 30, 2017, respectively, was lower than the statutory rate of 35.0% primarily due to a reduction in tax expense related to the expiration of statutes of limitations on various uncertain tax positions. In addition, the effective income tax rate was favorably impacted by $0.4 million and $13.5 million of excess tax benefits related to equity-based compensation awards for the three and nine months ended September 30, 2017, respectively. Such benefits, which were previously reflected in additional paid-in capital, are now recognized in income tax expense as a result of the adoption of Accounting Standards Update (ASU) No. 2016-09. See the discussion under Recent Accounting Pronouncements for further information regarding the adoption of this new accounting guidance. Offsetting these decreases for the three and nine months ended September 30, 2017 was the effect of the provision for state income taxes. The effective income tax rate of 11.4% and 24.6% for the three and nine months ended September 30, 2016, respectively, was lower than the statutory rate of 35.0% primarily due to a reduction in tax expense related to the expiration of statutes of limitations on various uncertain tax positions and the release of valuation allowances related to certain foreign deferred tax assets. The effective income tax rate was also favorably affected by the impact of earnings in foreign jurisdictions that the Company does not plan to repatriate. These earnings are generally taxed at rates lower than the United States (U.S.) statutory rate. Offsetting these decreases for the nine months ended September 30, 2016 was the effect of the provision for state income taxes as well as the goodwill impairment for which only partial tax benefits were recorded. 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 (1.7 million shares and 1.3 million shares for the three and nine months ended September 30, 2017, respectively, and 1.4 million shares and 1.5 million shares for the three and nine months ended September 30, 2016, respectively). During the three and nine months ended September 30, 2017, the Company repurchased 2.3 million shares and 4.8 million shares, respectively, of its common stock. The Company did not repurchase any of its common stock during the three and nine months ended September 30, 2016. See Note 11 for more information on the share repurchase programs.

Under the new guidance, lessees are required to recognize assets and lease liabilities for the rights and obligations created by leased assets previously classified as operating leases In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (except those accounted for under the equity method of accounting) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers The Company has completed an impact assessment and determined that adoption of the standard will likely result in an acceleration of when revenues are recognized for certain contracts containing multiple performance obligations. These contract revenues are currently accounted for using the multi-element guidance and are primarily for certain metro cell, distributed antenna system (DAS) and small cell solutions within the CommScope Mobility Solutions (CMS) segment. These multi-element revenue contracts represented less than 2% of total net sales for the three and nine months ended September 30, 2017. Due to the short-term nature of most of the contracts, the impact to the Company’s consolidated financial statements at adoption will be based on customer-specific contract terms in effect at that time and could be significant. The Company is in the process of implementing the necessary changes to its accounting policies, processes, internal controls and information systems that will be required to meet the new standard’s reporting and disclosure requirements. 2

Business Combinations [Abstract]
Acquisitions	2. ACQUISITIONS On August 1, 2017, the Company acquired Cable Exchange in an all cash transaction. The Company paid $108.7 million ($105.2 million net of cash acquired) and recorded a $14.5 million liability for the remaining payments due. Cable Exchange is a quick-turn supplier of fiber optic and copper assemblies for data, voice and video communications. Net sales of Cable Exchange products reflected in the Condensed Consolidated Statement of Operations and Comprehensive Income for the three months ended September 30, 2017 were not material to the CCS segment. The preliminary allocation of the purchase price, based on estimates of the fair values of the assets acquired and liabilities assumed, is as follows (in millions): Estimated Fair Value Cash and cash equivalents $ 3.5 Accounts receivable 6.4 Inventory 4.4 Property, plant and equipment 0.9 Goodwill 49.6 Identifiable intangible assets 61.1 Less: Liabilities assumed (2.7 ) Net acquisition cost $ 123.2 The goodwill arising from the purchase price allocation of the Cable Exchange acquisition is believed to result from the Company’s reputation in the marketplace and assembled workforce and is expected to be deductible for income tax purposes. As additional information is obtained, adjustments may be made to the preliminary purchase price allocation. The Company is still finalizing the estimated fair value of certain tangible and intangible assets acquired and liabilities assumed. On August 28, 2015, the Company acquired TE Connectivity’s BNS business for approximately $3.0 billion in an all-cash transaction. During the nine months ended September 30, 2016, the Company received $3.7 million in net settlements for certain adjustments related to the BNS acquisition. Also during the three and nine months ended September 30, 2016, the Company recorded measurement period adjustments primarily related to the finalization of the valuation of inventory, intangible assets, plant and equipment, pension liabilities and deferred taxes. The impact of these measurement period adjustments was not material to the Company’s results.

Interest is payable on the 2027 Notes semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2017. The Company used the proceeds of the issuance of the 2027 Notes, together with cash on hand, to (i) redeem all of the 2020 Notes, (ii) repay a portion of the outstanding borrowings under its senior secured term loans, including all $111.9 million of outstanding principal on the senior secured term loan due 2018 and $138.1 million of outstanding principal on the senior secured term loan due 2022 (the 2022 Term Loan), and (iii) pay related fees and expenses. The redemption of the 2020 Notes resulted in a $14.8 million charge which is reflected in other income (expense), net. In connection with the redemption of the 2020 Notes and prepayments of the senior secured term loans, $9.6 million of debt issuance costs and original issue discount were written off and included in interest expense. CommScope, Inc., a wholly owned subsidiary of the Company, and each of CommScope, Inc.’s existing and future domestic subsidiaries (other than CommScope Technologies) that guarantee the senior secured credit facilities also guarantees the 2027 Notes on a senior unsecured basis, subject to certain exceptions. The 2027 Notes rank senior in right of payment with all of CommScope Technologies’ and the guarantors’ future subordinated indebtedness and equally in right of payment with all of CommScope Technologies’ and the guarantors’ existing and future senior indebtedness, including the senior secured credit facilities, the 2025 Notes, the 2024 Notes and the 2021 Notes. The 2027 Notes and guarantees are effectively junior to all of CommScope Technologies’ and the guarantors’ existing and future secured indebtedness, including the senior secured credit facilities, to the extent of the value of the assets securing such secured indebtedness. In addition, the 2027 Notes are structurally subordinated to all existing and future liabilities (including trade payables) of CommScope, Inc.’s subsidiaries that do not guarantee the 2027 Notes, including indebtedness incurred by certain of CommScope, Inc.’s non-U.S. subsidiaries under the revolving credit facility. The 2027 Notes may be redeemed prior to maturity under certain circumstances. Upon certain change of control events, the 2027 Notes may be redeemed at the option of the holders at 101% of their principal amount, plus accrued and unpaid interest. The 2027 Notes may be redeemed on or after March 15, 2022 at the redemption prices specified in the indenture governing the 2027 Notes. Prior to March 15, 2022, the 2027 Notes may be redeemed at a redemption price equal to 100% of the aggregate principal amount of the 2027 Notes to be redeemed, plus a make-whole premium (as specified in the indenture governing the 2027 Notes), plus accrued and unpaid interest. At any time prior to March 15, 2020, CommScope Technologies may also redeem up to 40% of the aggregate principal amount of the 2027 Notes at a redemption price of 105%, plus accrued and unpaid interest, using the proceeds of certain equity offerings. In connection with issuing the 2027 Notes, the Company paid $7.2 million of debt issuance costs during the nine months ended September 30, 2017, which was recorded as a reduction of the carrying amount of the debt and is being amortized over the term of the notes. Senior Secured Credit Facilities During May 2017, the Company amended the 2022 Term Loan to reduce the interest rate margin. The interest rate is, at the Company’s option, either (1) the base rate (as described in the credit agreement, as amended) plus a margin of 1.00% or (2) one-, two-, three- or six-month LIBOR or, if available from all lenders, twelve-month LIBOR (selected at the Company’s option) plus a margin of 2.00%. Before the amendment, the margin on the interest rate with respect to base rate loans was 1.50% and with respect to LIBOR loans was 2.50%. The amendment also reduced the 1.75% base rate floor to 1.00% and eliminated the 0.75% LIBOR floor. The amendment resulted in the repayment of $30.4 million to certain lenders under the senior secured credit facilities and the receipt of $30.4 million in proceeds from new lenders and existing lenders who increased their positions. In conjunction with the amendment, the Company recorded $1.1 million of debt modification costs in other income (expense), net. During the quarter ended September 30, 2017, the Company repaid $25.0 million of the 2022 Term Loan. In connection with this voluntary repayment, $0.5 million of original issue discount and debt issuance costs were written off and included in interest expense. No portion of the senior secured term loan was reflected as a current portion of long-term debt as of September 30, 2017 related to the potentially required excess cash flow payment because the amount that may be payable in 2018, if any, cannot currently be reliably estimated. There was no excess cash flow payment required in 2017 related to 2016. During the nine months ended September 30, 2017, the Company did not borrow under its revolving credit facility. As of September 30, 2017, the Company had availability of approximately $415.8 million under the asset-based revolving credit facility, after giving effect to borrowing base limitations and outstanding letters of credit. Other Matters The following table summarizes scheduled maturities of long-term debt as of September 30, 2017 (in millions): Remainder of 2017 2018 2019 2020 2021 Thereafter Scheduled maturities of long-term debt $ — $ — $ — $ — $ 650.0 $ 3,971.3 The Company’s non-guarantor subsidiaries held $2,603 million, or 36%, of total assets and $532 million, or 10%, of total liabilities as of September 30, 2017 and accounted for $494 million, or 44%, and $1,405 million, or 41%, of net sales for the three and nine months ended September 30, 2017, respectively. As of December 31, 2016, the non-guarantor subsidiaries held $2,211 million, or 31%, of total assets and $615 million, or 11%, of total liabilities. For the three and nine months ended September 30, 2016, the non-guarantor subsidiaries accounted for approximately $526 million, or 41%, and $1,586 million, or $42%, of net sales, respectively. All amounts presented exclude intercompany balances. The weighted average effective interest rate on outstanding borrowings, including the amortization of debt issuance costs and original issue discount, was 5.34% and 5.24% at September 30, 2017 and December 31, 2016, respectively.

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 September 30, 2017, the Company had foreign exchange contracts outstanding with maturities of up to twelve months and aggregate notional values of $291 million (based on exchange rates as of September 30, 2017). 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 and are not designated as hedges for hedge accounting and are marked to market each period through earnings.

As of September 30, 2017, the Company held forward contracts with outstanding maturities of less than three months and aggregate notional values of $75.0 million. Hedge effectiveness is assessed each quarter based on the net investment in the foreign subsidiary designated as the hedged item and the overall changes in the fair value of the forward contracts. For hedges that meet the effectiveness requirements, changes in fair value are recorded as a component of other comprehensive income, net of tax. Any change in fair value that is the result of ineffectiveness is recognized immediately in earnings. As of September 30, 2017, there was no ineffectiveness on the instruments designated as net investment hedges.

Fair Value Measurements	7. FAIR VALUE MEASUREMENTS The Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, available-for-sale securities, debt instruments and foreign currency contracts. For cash and cash equivalents, trade receivables and trade payables, the carrying amounts of these financial instruments as of September 30, 2017 and December 31, 2016 were considered representative of their fair values due to their short terms to maturity. The fair value of the Company’s available-for-sale securities was based on quoted market prices. The fair values of the Company’s debt instruments 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 available-for-sale securities, foreign currency contracts and debt instruments as of September 30, 2017 and December 31, 2016, are as follows: September 30, 2017 December 31, 2016 Carrying Amount Fair Value Carrying Amount Fair Value Valuation Inputs Assets: Available-for-sale securities $ — $ — $ 5,212 $ 5,212 Level 1 Foreign currency contracts 9,584 9,584 289 289 Level 2 Liabilities: 5.00% senior notes due 2027 750,000 753,975 — — Level 2 6.00% senior notes due 2025 1,500,000 1,606,950 1,500,000 1,585,350 Level 2 5.50% senior notes due 2024 650,000 682,500 650,000 673,530 Level 2 5.00% senior notes due 2021 650,000 666,250 650,000 669,500 Level 2 4.375% senior secured notes due 2020 — — 500,000 513,100 Level 2 Senior secured term loan due 2022, at par 1,071,250 1,080,597 1,234,375 1,245,145 Level 2 Senior secured term loan due 2018, at par — — 111,875 112,364 Level 2 Foreign currency contracts 7,932 7,932 8,349 8,349 Level 2 These fair value estimates are based on pertinent information available to management as of the valuation date.

Restructuring And Related Activities [Abstract]
Restructuring Costs	9. RESTRUCTURING COSTS Prior to the acquisition of the BNS business in 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. Production capacity from these facilities has been shifted to other existing facilities or unaffiliated suppliers. These actions are referred to as cost alignment restructuring actions. Following the acquisition of BNS, the Company initiated a series of restructuring actions, which are currently ongoing, to integrate the BNS operations (BNS integration restructuring actions) to achieve cost synergies. All charges related to these restructuring actions are reported in restructuring costs, net. The Company’s net pretax restructuring charges (credits), by segment, were as follows: Three Months Ended Nine Months Ended September 30, September 30, 2017 2016 2017 2016 CCS $ 5,569 $ 8,362 $ 19,922 $ 16,062 CMS (209 ) 2,464 4,599 8,441 Total $ 5,360 $ 10,826 $ 24,521 $ 24,503 The liability for restructuring actions is 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 relate to 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 activity within the liability established for the cost alignment restructuring actions was as follows: Employee- Related Costs Lease Termination Costs Fixed Asset Related Costs Total Balance at June 30, 2017 $ 359 $ 5,319 $ — $ 5,678 Additional charge recorded 86 66 — 152 Cash paid — (249 ) — (249 ) Foreign exchange and other non-cash items 15 — — 15 Balance at September 30, 2017 $ 460 $ 5,136 $ — $ 5,596 Balance at December 31, 2016 $ 311 $ 6,050 $ — $ 6,361 Additional charge (credit) recorded 86 (168 ) — (82 ) Cash paid — (746 ) — (746 ) Foreign exchange and other non-cash items 63 — — 63 Balance at September 30, 2017 $ 460 $ 5,136 $ — $ 5,596 The Company has recognized restructuring charges of $88.9 million since January 2011 for cost alignment restructuring actions. Additional pretax costs of $0.5 million are expected to be incurred to complete these previously announced initiatives. Cash payments of $1.0 million are expected during the remainder of 2017 with additional expected payments of $5.1 million between 2018 and 2022. 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 June 30, 2017 $ 31,380 $ 841 $ — $ 32,221 Additional charge recorded 2,789 273 2,146 5,208 Cash paid (15,289 ) (184 ) (25 ) (15,498 ) Consideration received — — 14 14 Foreign exchange and other non-cash items 16 — (2,135 ) (2,119 ) Balance at September 30, 2017 $ 18,896 $ 930 $ — $ 19,826 Balance at December 31, 2016 $ 32,740 $ 371 $ — $ 33,111 Additional charge recorded 21,029 979 2,595 24,603 Cash paid (34,974 ) (420 ) (550 ) (35,944 ) Consideration received — — 2,699 2,699 Foreign exchange and other non-cash items 101 — (4,744 ) (4,643 ) Balance at September 30, 2017 $ 18,896 $ 930 $ — $ 19,826 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 $91.1 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. Cash payments of $7.7 million are expected during the remainder of 2017 with additional expected payments of $12.1 million between 2018 and 2022. Future BNS integration activities are expected to be identified and the resulting amounts may be material. Restructuring reserves related to all actions were included in the Company’s Condensed Consolidated Balance Sheets as follows: September 30, 2017 December 31, 2016 Other accrued liabilities $ 17,479 $ 30,438 Other noncurrent liabilities 7,943 9,034 Total liability $ 25,422 $ 39,472

Equity [Abstract]
Stockholders' Equity	11. STOCKHOLDERS’ EQUITY Stock Repurchase Program On February 23, 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. The Company completed this repurchase plan in the first half of the year and repurchased $100.0 million of its common stock, or 2.5 million shares, at an average cost of $40.23 per share. The Company had no remaining authorization under this stock repurchase program at September 30, 2017. On August 3, 2017, the Company announced its Board of Directors had authorized another repurchase of up to $100.0 million of the Company’s outstanding common stock. Under this plan, during the three and nine months ended September 30, 2017, the Company repurchased $75.0 million of its common stock, or 2.3 million shares, at an average cost of $32.47 per share. The Company has $25.0 million remaining authorized under this stock repurchase program at September 30, 2017. The repurchase authorization expires on July 31, 2018. Equity-Based Compensation Plans As of September 30, 2017, $70.6 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 1.4 years. There were no significant capitalized equity-based compensation costs at September 30, 2017. The following table shows a summary of the equity-based compensation expense included in the Condensed Consolidated Statements of Operations and Comprehensive Income: Three Months Ended Nine Months Ended September 30, September 30, 2017 2016 2017 2016 Selling, general and administrative $ 8,365 $ 6,409 $ 24,041 $ 20,306 Cost of sales 1,386 1,104 4,001 3,551 Research and development 1,223 862 3,530 2,764 Total equity-based compensation expense $ 10,974 $ 8,375 $ 31,572 $ 26,621 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): Shares Weighted Average Option Exercise Price Per Share Weighted Average Remaining Contractual Term in Years Aggregate Intrinsic Value Options outstanding at June 30, 2017 4,990 $ 13.03 Granted — $ — Exercised (36 ) $ 8.22 Forfeited (18 ) $ 35.74 Options outstanding at September 30, 2017 4,936 $ 12.98 4.4 $ 102,118 Options outstanding at December 31, 2016 5,497 $ 10.33 Granted 484 $ 38.00 Exercised (957 ) $ 9.20 Forfeited (88 ) $ 26.14 Options outstanding at September 30, 2017 4,936 $ 12.98 4.4 $ 102,118 Options exercisable at September 30, 2017 4,039 $ 8.51 3.5 $ 99,771 Options expected to vest at September 30, 2017 897 $ 33.11 8.7 $ 2,347 The exercise prices of outstanding options at September 30, 2017 were in the following ranges: Options Outstanding Options Exercisable Range of Exercise Prices Shares (in thousands) Weighted Average Remaining Contractual Life (in years) Weighted Average Exercise Price Per Share Shares (in thousands) Weighted Average Exercise Price Per Share $2.96 to $5.74 2,688 3.1 $ 5.40 2,688 $ 5.40 $5.75 to $22.99 886 2.6 $ 8.64 886 $ 8.64 $23.00 to $42.32 1,362 8.2 $ 30.77 465 $ 26.25 $2.96 to $42.32 4,936 4.4 $ 12.98 4,039 $ 8.51 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, stock price volatility, the risk-free interest rate and the Company’s projected dividend yield. 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. The expected life represents the period over which the Company’s employees are expected to hold their options. Expected volatility is derived based on the historical Company volatility, as well as volatilities from publicly traded companies operating in the Company’s industry. The Company’s projected dividend yield is zero. The Company believes that 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 nine months ended September 30, 2017 and 2016. Three Months Ended Nine Months Ended September 30, September 30, 2017 2016 2017 2016 Expected option term (in years) * 6.0 6.0 6.0 Risk-free interest rate * 1.2 % 2.0 % 1.4 % Expected volatility * 50.0 % 40.0 % 50.0 % Weighted average exercise price * $ 29.59 $ 38.00 $ 25.08 Weighted average fair value at grant date * $ 14.17 $ 15.72 $ 12.09 * 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 June 30, 2017 2,422 $ 31.77 Granted 9 $ 37.15 Vested and shares issued (8 ) $ 27.77 Forfeited (50 ) $ 31.15 Non-vested RSUs at September 30, 2017 2,373 $ 31.81 Non-vested RSUs at December 31, 2016 2,519 $ 26.37 Granted 1,134 $ 37.90 Vested and shares issued (1,097 ) $ 26.10 Forfeited (183 ) $ 28.91 Non-vested RSUs at September 30, 2017 2,373 $ 31.81 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 150% 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 will be 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 June 30, 2017 559 $ 30.32 Granted — $ — Vested and shares issued — $ — Forfeited (20 ) $ 28.17 Non-vested PSUs at September 30, 2017 539 $ 30.40 Non-vested PSUs at December 31, 2016 445 $ 26.68 Granted 200 $ 38.00 Vested and shares issued (64 ) $ 30.76 Forfeited (42 ) $ 26.73 Non-vested PSUs at September 30, 2017 539 $ 30.40

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Condensed Consolidated Balance Sheet as of September 30, 2017, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2017 and 2016, and the Condensed Consolidated Statements of Cash Flows and Stockholders’ Equity for the nine months ended September 30, 2017 and 2016 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. 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, 2016 (the 2016 Annual Report). There were no changes in the Company’s significant accounting policies during the three or nine months ended September 30, 2017. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements. Prior to January 1, 2017, the Company consolidated the operating results of the acquired BNS business based on the BNS fiscal reporting calendar that resulted in a reporting lag of one day for the year ended December 31, 2016. The BNS business results included thirteen weeks for the three months ended September 30, 2017 compared to fourteen weeks for the comparable period in 2016. Effective January 1, 2017, the reporting lag was eliminated as a result of system conversions that were part of the BNS integration. The elimination of the reporting lag represents a change in accounting principle which the Company believes to be preferable because it provides more current information to the users of its financial statements. The Company determined that it was impracticable to apply the effects of the lag elimination to financial reporting periods prior to January 1, 2017. The cumulative effect of not retroactively applying this change in accounting, however, was immaterial as of January 1, 2017. Therefore, the Company reported the cumulative effect of the change in accounting principle in net income for the nine months ended September 30, 2017 and did not retrospectively apply the effects of this change to prior periods.
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 12% and 11% of the Company’s total net sales during the three and nine months ended September 30, 2017, respectively. Net sales to Anixter accounted for 11% of the Company’s total net sales during the three and nine months ended September 30, 2016. Sales to Anixter primarily originate within the CommScope Connectivity Solutions (CCS) segment. Other than Anixter, no direct customer accounted for 10% or more of the Company’s total net sales for the three or nine months ended September 30, 2017 or 2016. Accounts receivable from Anixter and Verizon Communications Inc. (Verizon) each represented approximately 11% of accounts receivable as of September 30, 2017. Other than Anixter and Verizon, no direct customer accounted for 10% or more of the Company’s accounts receivable as of September 30, 2017.
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 Nine Months Ended September 30, September 30, 2017 2016 2017 2016 Product warranty accrual, beginning of period $ 20,283 $ 18,356 $ 21,631 $ 17,964 Provision for warranty claims 284 3,435 4,515 7,954 Warranty claims paid (2,033 ) (106 ) (7,751 ) (4,517 ) Foreign exchange (62 ) 92 77 376 Product warranty accrual, end of period $ 18,472 $ 21,777 $ 18,472 $ 21,777
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. 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 and nine months ended September 30, 2017. During the nine months ended September 30, 2016, the Company recorded a $15.3 million goodwill impairment charge as a result of the change in its reportable segments. The impairment was recorded in the CCS segment. 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. During the three months and nine months ended September 30, 2016, as a result of revisions to the business plan for a particular product line, the Company determined that certain intangible assets in the CCS segment were no longer recoverable and a $7.4 million impairment charge was recorded. There were no asset impairments identified during the three and nine months ended September 30, 2017.
Income Taxes	Income Taxes The effective income tax rate of 24.8% and 23.6% for the three and nine months ended September 30, 2017, respectively, was lower than the statutory rate of 35.0% primarily due to a reduction in tax expense related to the expiration of statutes of limitations on various uncertain tax positions. In addition, the effective income tax rate was favorably impacted by $0.4 million and $13.5 million of excess tax benefits related to equity-based compensation awards for the three and nine months ended September 30, 2017, respectively. Such benefits, which were previously reflected in additional paid-in capital, are now recognized in income tax expense as a result of the adoption of Accounting Standards Update (ASU) No. 2016-09. See the discussion under Recent Accounting Pronouncements for further information regarding the adoption of this new accounting guidance. Offsetting these decreases for the three and nine months ended September 30, 2017 was the effect of the provision for state income taxes. The effective income tax rate of 11.4% and 24.6% for the three and nine months ended September 30, 2016, respectively, was lower than the statutory rate of 35.0% primarily due to a reduction in tax expense related to the expiration of statutes of limitations on various uncertain tax positions and the release of valuation allowances related to certain foreign deferred tax assets. The effective income tax rate was also favorably affected by the impact of earnings in foreign jurisdictions that the Company does not plan to repatriate. These earnings are generally taxed at rates lower than the United States (U.S.) statutory rate. Offsetting these decreases for the nine months ended September 30, 2016 was the effect of the provision for state income taxes as well as the goodwill impairment for which only partial tax benefits were recorded.
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 (1.7 million shares and 1.3 million shares for the three and nine months ended September 30, 2017, respectively, and 1.4 million shares and 1.5 million shares for the three and nine months ended September 30, 2016, respectively).

Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted During the Nine Months Ended September 30, 2017 The Company adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, The Company also adopted ASU No. 2016-15, Cash Flow Classification of Certain Cash Receipts and Cash Payments Issued but Not Adopted In March 2017, the Financial Accounting Standards Board (FASB) issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost 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. Under the new guidance, lessees are required to recognize assets and lease liabilities for the rights and obligations created by leased assets previously classified as operating leases In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (except those accounted for under the equity method of accounting) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers The Company has completed an impact assessment and determined that adoption of the standard will likely result in an acceleration of when revenues are recognized for certain contracts containing multiple performance obligations. These contract revenues are currently accounted for using the multi-element guidance and are primarily for certain metro cell, distributed antenna system (DAS) and small cell solutions within the CommScope Mobility Solutions (CMS) segment. These multi-element revenue contracts represented less than 2% of total net sales for the three and nine months ended September 30, 2017. Due to the short-term nature of most of the contracts, the impact to the Company’s consolidated financial statements at adoption will be based on customer-specific contract terms in effect at that time and could be significant. The Company is in the process of implementing the necessary changes to its accounting policies, processes, internal controls and information systems that will be required to meet the new standard’s reporting and disclosure requirements.
