Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Consolidation The accompanying consolidated financial statements include CommScope Holding Company, Inc., along with its direct and indirect subsidiaries. All intercompany accounts and transactions are eliminated in consolidation. Prior to January 1, 2017, the Company consolidated the operating results of the Broadband Network Solutions (BNS) business acquired from TE Connectivity 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 52 weeks for the year ended December 31, 2017 compared to 53 weeks for the year ended December 31, 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, and therefore, reported the cumulative effect of the change in accounting principle in net income for the year ended December 31, 2017. Certain prior year amounts have been reclassified to conform to the current year presentation. Use of Estimates in the Preparation of the Financial Statements The preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and their underlying assumptions form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other objective sources. The Company bases its estimates on historical experience and 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. Significant accounting estimates reflected in the Company’s financial statements include the allowance for doubtful accounts; reserves for sales returns, discounts, allowances, rebates and distributor price protection programs; inventory excess and obsolescence reserves; product warranty reserves and other contingent liabilities; tax valuation allowances; liabilities for unrecognized tax benefits; purchase price allocations; impairment reviews for investments, fixed assets, goodwill and other intangibles; and pension and other postretirement benefit costs and liabilities. Although these estimates are based on management’s knowledge of and experience with past and current events and on management’s assumptions about future events, it is at least reasonably possible that they may ultimately differ materially from actual results. Cash and Cash Equivalents Cash and cash equivalents represent deposits in banks and cash invested temporarily in various instruments with a maturity of three months or less at the time of purchase. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are stated at the amount owed by the customer, net of allowances for estimated doubtful accounts, discounts, returns and rebates. The Company maintains Inventories Inventories are stated at the lower of cost or net realizable value. Inventory cost is determined on a first-in, first-out (FIFO) basis. Costs such as idle facility expense, excessive scrap and re-handling costs are expensed as incurred. The Company maintains reserves to reduce the value of inventory to the lower of cost or net realizable value, including reserves for excess and obsolete inventory. Long-Lived Assets Property, Plant and Equipment Property, plant and equipment are stated at cost. Upon application of acquisition accounting, property, plant and equipment are measured at estimated fair value as of the acquisition date to establish a new historical cost basis. Provisions for depreciation are based on estimated useful lives of the assets using the straight-line method. Useful lives generally range from 10 to 35 years for buildings and improvements and 3 to 10 years for machinery and equipment. Expenditures for repairs and maintenance are expensed as incurred. Assets that management intends to dispose of and that meet held for sale criteria are carried at the lower of the carrying value or fair value less costs to sell. Goodwill and Other Intangible Assets Goodwill is assigned to reporting units based on the difference between the purchase price as allocated to the reporting units and the estimated fair value of the identified net assets acquired as allocated to the reporting units. Purchased intangible assets with finite lives are carried at their estimated fair values at the time of acquisition less accumulated amortization and any impairment charges. Amortization is recognized on a straight-line basis over the estimated useful lives of the respective assets (see Note 4). 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. 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. See Notes 4 and 8 for discussion of impairment charges. Due to uncertain market conditions, it is possible that future impairment reviews may indicate additional impairments of goodwill, other intangible assets and/or property, plant and equipment, which could result in charges that are material to the Company’s results of operations. Income Taxes Deferred income taxes reflect the future tax consequences of differences between the financial reporting and tax basis of assets and liabilities. The Company records a valuation allowance, when appropriate, to reduce deferred tax assets to an amount that is more likely than not to be realized. Tax benefits that result from uncertain tax positions may be recognized only if they are considered more likely than not to be sustainable, based on their technical merits. The amount of benefit to be recognized is the largest amount of tax benefit that is at least 50% likely to be realized. In addition, the Company does not provide for U.S. taxes related to the foreign currency remeasurement gains and losses on its long-term intercompany loans with foreign subsidiaries. These loans are not expected to be repaid in the foreseeable future, and the foreign currency gains and losses are therefore recorded to accumulated other comprehensive loss. 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. The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset would be one year or less. 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. The Company includes shipping and handling costs billed to customers in net sales and includes the costs incurred to transport product to customers as cost of sales. Shipping and handling costs incurred after control is transferred to the customer are accounted for as fulfillment costs and are not accounted for as separate revenue obligations. Certain internal handling costs, which relate to activities to prepare goods for shipment, are recorded in selling, general and administrative expense and were $55.0 million, $62.1 million and $56.2 million for the years ended December 31, 2018, 2017 and 2016, respectively. Tax Collected from Customers Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, which are collected by the Company from customers, are excluded from revenue. Product Warranties The Company recognizes a liability for the estimated claims that may be paid under its customer assurance-type 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. Advertising Costs Advertising costs are expensed in the period in which they are incurred. Advertising expense was $17.3 million, $21.2 million and $20.0 million for the years ended December 31, 2018, 2017 and 2016, respectively. Research and Development Research and development (R&D) costs are expensed in the period in which they are incurred. R&D costs include materials and equipment that have no alternative future use, depreciation on equipment and facilities currently used for R&D purposes, personnel costs, contract services and reasonable allocations of indirect costs, if clearly related to an R&D activity. Expenditures in the pre-production phase of an R&D project are recorded as R&D expense. However, costs incurred in the pre-production phase that are associated with output actually used in production are recorded in cost of sales. A project is considered finished with pre-production efforts when management determines that it has achieved acceptable levels of scrap and yield, which vary by project. Expenditures related to ongoing production are recorded in cost of sales. Derivative Instruments and Hedging Activities CommScope is exposed to risks resulting from adverse fluctuations in commodity prices, interest rates and foreign currency exchange rates. CommScope’s risk management strategy includes the use of derivative financial instruments whenever management determines their use to be reasonable and practical. This strategy does not permit the use of derivative financial instruments for trading or speculation. Derivative contracts not designated as hedging instruments are measured at fair value and are marked to market each period through earnings. During 2017, the Company began a hedging strategy to designate certain foreign exchange forward contracts as net investment hedges to mitigate a portion of the foreign currency risk on the euro net investment in a foreign subsidiary. 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 designated forward contracts. For hedges that meet the effectiveness requirements, changes in fair value are recorded as a component of other comprehensive income (loss), net of tax. The Company did not designate any transactions as hedges in the year ended December 31, 2016. 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 interest expense over the life of each contract. See Note 7 for further disclosure related to the derivative instruments and hedging activities. The Company has elected and documented the use of the normal purchases and sales exception for normal purchase and sales contracts that meet the definition of a derivative financial instrument. Foreign Currency Translation For the years ended December 31, 2018, 2017 and 2016, approximately 44%, 46% and 46%, respectively, of the Company’s net sales were to customers located outside the U.S. A portion of these sales were denominated in currencies other than the U.S. dollar, particularly sales from the Company’s foreign subsidiaries. The financial position and results of operations of certain of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Revenues and expenses of these subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities of these subsidiaries have been translated at the exchange rates as of the balance sheet date. Translation gains and losses are recorded in accumulated other comprehensive loss. Upon sale or liquidation of an investment in a foreign subsidiary, the amount of net translation gains or losses that have been accumulated in other comprehensive loss attributable to that investment are reported as a gain or loss in earnings in the period in which the sale or liquidation occurs. During the year ended December 31, 2018, the Company liquidated a foreign subsidiary and recognized $14.0 million in translation losses in other expense, net that had been in accumulated other comprehensive loss. Aggregate foreign currency gains and losses, such as those resulting from the settlement of receivables or payables, foreign currency contracts and short-term intercompany advances in a currency other than the subsidiary’s functional currency, are recorded currently in earnings (included in other expense, net) and resulted in losses of $15.9 million, $8.7 million and $9.5 million during the years ended December 31, 2018, 2017 and 2016, respectively. Foreign currency remeasurement gains and losses related to certain long-term intercompany loans that are not expected to be settled in the foreseeable future and the effective portion of foreign currency contracts designated as net investment hedges are recorded in accumulated other comprehensive loss. See Note 7 for disclosure of foreign currency gains and losses specifically related to foreign currency contracts. Equity-Based Compensation The estimated fair value of stock awards is recognized as expense over the requisite service periods. Forfeitures of stock awards are recognized as they occur. The Company records deferred tax assets related to compensation expense for awards that are expected to result in future tax deductions for the Company, based on the amount of compensation cost recognized and the Company’s statutory tax rate in the jurisdiction in which it expects to receive a deduction. Differences between the deferred tax assets recognized for financial reporting purposes and actual tax deductions reported on the Company’s income tax return are recorded in the Consolidated Statements of Operations and Comprehensive Income within income tax expense. 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 dilutive effect of potential common shares outstanding during the period using the treasury stock method. Dilutive potential 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 condition was not met (2.1 million, 1.5 million and 1.0 million shares for the years ended December 31, 2018, 2017 and 2016, respectively). The following table presents the basis for the earnings per share computations: Year Ended December 31, 2018 2017 2016 Numerator: Net income for basic and diluted earnings per share $ 140,217 $ 193,764 $ 222,838 Denominator: Weighted average common shares outstanding - basic 192,022 192,430 192,470 Dilutive effect of equity-based awards 3,310 4,381 3,989 Weighted average common shares outstanding - diluted 195,332 196,811 196,459 Earnings per share: Basic $ 0.73 $ 1.01 $ 1.16 Diluted $ 0.72 $ 0.98 $ 1.13 Business Combinations The Company uses the acquisition method of accounting for business combinations which requires the allocation of the acquisition date fair value to the underlying tangible and intangible assets acquired and liabilities assumed based on their respective fair market value. Goodwill represents the excess of the consideration transferred over the fair value of the net assets acquired. The fair values of the assets acquired and liabilities assumed are determined based upon the Company’s valuation and involves making significant estimates and assumptions based on facts and circumstances that existed as of the acquisition date. The Company uses a measurement period following the acquisition date to gather information that existed as of the acquisition date that is needed to determine the fair value of the assets acquired and liabilities assumed. The measurement period ends once all information is obtained, but no later than one year from the acquisition date. Concentrations of Risk Non-derivative financial instruments used by the Company in the normal course of business include letters of credit and commitments to extend credit, primarily accounts receivable. The Company generally does not require collateral on its accounts receivable. These financial instruments involve risk, including the credit risk of nonperformance by the counterparties to those instruments, and the actual loss may exceed the reserves provided in the Company’s balance sheet. See Note 14 for further discussion of customer-related concentrations of risk. The Company manages its exposures to credit risk associated with accounts receivable using such tools as credit approvals, credit limits and monitoring procedures. CommScope estimates the allowance for doubtful accounts based on the actual payment history and individual circumstances of significant customers as well as the age of receivables. In management’s opinion, as of December 31, 2018, the Company did not have significant unreserved risk of credit loss due to the non-performance of customers or other counterparties related to amounts receivable. However, an adverse change in financial condition of a significant customer or group of customers or in the telecommunications industry could materially affect the Company’s estimates related to doubtful accounts. The principal raw materials purchased by CommScope (aluminum, bimetals, copper, optical fiber, plastics and other polymers and steel) are subject to changes in market price as these materials are linked to various commodity markets. The Company attempts to mitigate these risks through effective requirements planning and by working closely with its key suppliers to obtain the best possible pricing and delivery terms. Recent Accounting Pronouncements Adopted in 2018 In the fourth quarter of 2018, the Company early adopted ASU No. 2018-14, Disclosure Framework: Changes to the Disclosure Requirements for Defined Benefit Plans, In the fourth quarter of 2018, the Company early adopted ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income 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 years ended December 31, 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 Consolidated Balance Sheets. This adjustment reflects an acceleration of $8.0 million of net sales. The impact of adoption of the new revenue recognition standard on the consolidated financial statements was as follows: Year Ended December 31, 2018 As Reported Amounts Without Adoption of ASU No. 2014-09 Effect of Change Increase / (Decrease) Net sales $ 4,568,507 $ 4,572,634 $ (4,127 ) Cost of sales 2,880,223 2,881,920 (1,697 ) Operating income 449,968 452,398 (2,430 ) Income tax expense 30,495 31,117 (622 ) Net income 140,217 142,025 (1,808 ) As of December 31, 2018 As Reported Amounts Without Adoption of ASU No. 2014-09 Effect of Change Increase / (Decrease) Assets: Accounts receivable, less allowance for doubtful accounts $ 810,359 $ 808,381 $ 1,978 Inventories, net 473,327 475,008 (1,681 ) Liabilities: Other accrued liabilities 291,385 292,693 (1,308 ) Stockholders' equity: Retained earnings (accumulated deficit) (249,777 ) (251,382 ) 1,605 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 August 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement (CCA) that is a Service Contract, 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.

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 year ended December 31, 2017, which was recorded as a reduction of the carrying amount of the debt and is being amortized over the term of the notes. 6.00% Senior Notes Due 2025 In June 2015, CommScope Technologies issued $1.5 billion of the 2025 Notes. Interest is payable on the 2025 Notes semi-annually in arrears on June 15 and December 15 of each year. The 2025 Notes are guaranteed on a senior unsecured basis by CommScope, Inc. and each of CommScope, Inc.’s existing and future domestic subsidiaries (other than CommScope Technologies) that guarantees the senior secured credit facilities, subject to certain exceptions, and rank as described above for the 2027 notes. The 2025 Notes may be redeemed prior to maturity under certain circumstances. Upon certain change of control events, the 2025 Notes may be redeemed at the option of the holders at 101% of their principal amount, plus accrued and unpaid interest.

Interest is payable on the 2021 Notes and the 2024 Notes semi-annually in arrears on June 15 and December 15 of each year. The 2021 Notes and the 2024 Notes are guaranteed on a senior unsecured basis by each of CommScope, Inc.’s existing and future domestic subsidiaries that guarantees the senior secure credit facilities, subject to certain exceptions, and rank as described above for the 2027 Notes. The 2021 Notes and the 2024 Notes may be redeemed prior to maturity under certain circumstances. Upon certain change of control events, the 2021 Notes and the 2024 Notes may be redeemed at the option of the holders at 101% of their principal amount, plus accrued and unpaid interest to the date of purchase. The 2021 Notes and the 2024 Notes may be redeemed on or after June 15, 2017 or June 15, 2019, respectively, at the redemption prices specified in the respective indentures governing the 2021 Notes and the 2024 Notes. Prior to June 15, 2019, the 2024 Notes may be redeemed at a redemption price equal to 100% of the aggregate principal amount, plus a make-whole premium (as specified in the indentures governing the 2024 Notes), plus accrued and unpaid interest to the redemption date. Senior Secured Credit Facilities The Company’s asset-based revolving credit facility provides borrowing capacity of up to $550.0 million, subject to certain limitations. The asset-based revolving credit facility expires in May 2020, subject to acceleration under certain circumstances. As of December 31, 2018, the Company had no outstanding borrowings under its asset-based revolving credit facility and had availability of $463.1 million after giving effect to borrowing base limitations and outstanding letters of credit. As of December 31, 2018, the Company had one term loan outstanding under its senior secured credit facilities, the senior secured term loan due 2022 (the 2022 Term Loan). In July 2018, the Company repaid $400.0 million of the 2022 Term Loan. The payment was made using $250.0 million of cash on hand and $150.0 million borrowed under the Company’s asset-based revolving credit facility. In connection with this voluntary repayment, $7.4 million of original issue discount and debt issuance costs were written off and included in interest expense. The Company subsequently repaid the $150.0 million borrowed under the asset-based revolving credit facility in September 2018. In 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 expense, net. During the year ended December 31, 2017, the Company repaid $348.1 million of the 2022 Term Loan and $111.9 million of the senior secured term loan due 2018. In connection with these repayments, $8.3 million of original issue discount and debt issuance costs were written off and included in interest expense. During the year ended December 31, 2016, the Company amended the 2022 Term Loan to reduce the margin on the interest rate and recorded an additional $3.1 million of original issue discount related to this amendment. During the year ended December 31, 2016, the Company voluntarily repaid $150.0 million, of its senior secured term loans. In connection with the repayment, combined original issue discount and debt issuance costs of $1.0 million were written off and included in interest expense during the year ended December 31, 2016. The 2022 Term Loan is secured by a first priority lien on certain of the Company’s non-current assets in the U.S. and a second priority lien on current assets in the U.S. The asset-based revolving credit facility is secured by a first priority lien on certain of the Company’s current assets in the U.S. and several European countries and a second priority lien on the Company’s non-current assets in the U.S. No portion of the 2022 Term Loan was reflected as a current portion of long-term debt as of December 31, 2018 related to the potentially required excess cash flow payment because no such payment is expected to be required. There was no excess cash flow payment required in 2018 related to 2017. Other Matters The following table summarizes scheduled maturities of long-term debt as of December 31, 2018 (in millions): 2019 2020 2021 2022 2023 Thereafter Scheduled maturities of long-term debt $ — $ — $ 650.0 $ 486.3 $ — $ 2,900.0 The Company’s non-guarantor subsidiaries held $2,354 million, or 36%, of total assets and $454 million, or 9%, of total liabilities as of December 31, 2018 and accounted for $1,835 million, or 40%, of net sales for the year ended December 31, 2018. As of December 31, 2017, the non-guarantor subsidiaries held $2,587 million, or 37%, of total assets and $569 million, or 11%, of total liabilities. For the year ended December 31, 2017, the non-guarantor subsidiaries accounted for $1,915 million, or 42%, of net sales. All amounts presented exclude intercompany balances. The Company is dependent upon the earnings and cash flow of its subsidiaries to make certain payments, including debt and interest payments. Certain subsidiaries may have limitations or restrictions on transferring funds to other subsidiaries that may be necessary to meet those requirements. The weighted average effective interest rate on outstanding borrowings, including the amortization of debt issuance costs and original issue discount, was 5.73% at December 31, 2018 and 5.45% at December 31, 2017.

Derivatives and Hedging Activities	7. 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 December 31, 2018, the Company had foreign exchange contracts outstanding with maturities of up to nine months and aggregate notional values of $363 million (based on exchange rates as of December 31, 2018). Unrealized gains and losses resulting from these contracts are recognized in other 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. 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) December 31, Balance Sheet Location 2018 2017 Foreign currency contracts Prepaid expenses and other current assets $ 1,703 $ 9,050 Foreign currency contracts Other accrued liabilities (3,044 ) (574 ) Total derivatives not designated as hedging instruments $ (1,341 ) $ 8,476 The pretax impact of the foreign currency forward contracts, both matured and outstanding, on the Consolidated Statements of Operations and Comprehensive Income is as follows: Foreign Currency Forward Contracts Location of Gain (Loss) Gain (Loss) Recognized Year ended December 31, 2018 Other expense, net $ (17,833 ) Year ended December 31, 2017 Other expense, net $ 28,633 Year ended December 31, 2016 Other expense, net $ (21,470 ) Derivative Instruments Designated As Net Investment Hedge During 2017, the Company began 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 December 31, 2018, the Company held designated forward contracts with an outstanding maturity of up to twelve months and an aggregate notional value of $40 million. The amortization of the spot-forward differences recorded to earnings was not material for the year ended December 31, 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 December 31, 2018, there was no ineffectiveness on the instruments designated as net investment hedges.

Fair Value Measurements	8. FAIR VALUE MEASUREMENTS The Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, debt instruments and foreign currency contracts. For cash and cash equivalents, trade receivables and trade payables, the carrying amounts of these financial instruments as of December 31, 2018 and December 31, 2017 were considered representative of their fair values due to their short terms to maturity. 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 foreign currency contracts and debt instruments as of December 31, 2018 and December 31, 2017, are as follows: December 31, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Valuation Inputs Assets: Foreign currency contracts $ 2,491 $ 2,491 $ 9,050 $ 9,050 Level 2 Liabilities: 5.00% senior notes due 2027 750,000 608,025 750,000 753,750 Level 2 6.00% senior notes due 2025 1,500,000 1,355,550 1,500,000 1,591,800 Level 2 5.50% senior notes due 2024 650,000 591,825 650,000 676,780 Level 2 5.00% senior notes due 2021 650,000 641,875 650,000 661,375 Level 2 Senior secured term loan due 2022, at par 486,250 461,938 886,250 892,343 Level 2 Foreign currency contracts 3,044 3,044 977 977 Level 2 Non-Recurring Fair Value Measurements During the fourth quarter of 2018, the Company recorded a pretax charge of $15.0 million that was allocated equally to the CCS and CMS segments to fully impair our equity investment in a privately-held company. The determination of the impairment charge was based on Level 3 valuation inputs. These fair value estimates are based on pertinent information available to management as of the valuation date. Although management is not aware of any factors that would significantly affect these fair value estimates, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates, and current estimates of fair value may differ significantly from the amounts presented.

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 both inside and outside the U.S. 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: Year Ended December 31, 2018 2017 2016 CCS $ 24,201 $ 36,551 $ 27,098 CMS 19,824 7,231 15,777 Total $ 44,025 $ 43,782 $ 42,875 Restructuring reserves were included in the Company’s Consolidated Balance Sheets as follows: December 31, 2018 2017 Other accrued liabilities $ 29,876 $ 24,961 Other noncurrent liabilities 5,179 7,036 Total liability $ 35,055 $ 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 December 31, 2018, these actions were substantially complete except for a $5.6 million liability for lease termination costs, for which the Company expects to make cash payments, net of sublease income, of $1.9 million during 2019 and make the remaining payments of $3.7 million between 2020 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 December 31, 2015 $ 28,714 $ — $ — $ 28,714 Additional charge recorded 35,848 378 6,483 42,709 Cash paid (31,569 ) (256 ) (3,079 ) (34,904 ) Foreign exchange and other non-cash items (253 ) 249 (3,404 ) (3,408 ) Balance at December 31, 2016 32,740 371 — 33,111 Additional charge recorded 33,565 1,352 8,202 43,119 Cash paid (41,084 ) (648 ) (582 ) (42,314 ) Consideration received — — 2,699 2,699 Foreign exchange and other non-cash items 367 5 (10,319 ) (9,947 ) Balance at December 31, 2017 25,588 1,080 — 26,668 Additional charge recorded 41,040 1,570 (821 ) 41,789 Cash paid (37,073 ) (2,343 ) (803 ) (40,219 ) Consideration received — — 11,123 11,123 Foreign exchange and other non-cash items (376 ) (23 ) (9,499 ) (9,898 ) Balance at December 31, 2018 $ 29,179 $ 284 $ — $ 29,463 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 $151.4 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 $28.0 million during 2019 and additional cash payments of $1.5 million between 2020 and 2021. Future restructuring actions may be identified and the resulting charges and cash requirements may be material.

Employee Benefit Plans	10. EMPLOYEE BENEFIT PLANS Defined Contribution Plans The Company and certain of its subsidiaries have defined contribution retirement savings plans, the most significant of which is a 401(k) plan in the U.S. These plans allow employees meeting certain requirements to contribute a portion of their compensation on a pretax and/or after-tax basis in accordance with guidelines established by the plans and the Internal Revenue Service or other tax authorities. The Company matches a percentage of the employee contributions up to certain limits. During the years ended December 31, 2018, 2017 and 2016, the Company made contributions to defined contribution retirement savings plans of $24.0 million, $25.9 million and $24.5 million, respectively. The Company maintains noncontributory and contributory deferred compensation plans. During the years ended December 31, 2018, 2017 and 2016, the Company recognized pretax costs of $0.7 million, $2.9 million and $2.6 million, respectively, related to these plans. The liability related to these plans was $32.6 million and $38.7 million as of December 31, 2018 and 2017, respectively. Pension Plans The Company sponsors defined benefit pension plans covering certain domestic former employees and certain foreign current and former employees. Included in the defined benefit pension plans are both funded and unfunded plans. The following table summarizes information for the defined benefit pension plans: December 31, U.S. Plans Non-U.S. Plans 2018 2017 2018 2017 Change in benefit obligation: Benefit obligation, beginning $ 156,729 $ 156,522 $ 240,749 $ 216,634 Service cost — — 4,097 4,876 Interest cost 4,205 5,929 5,157 5,300 Plan participants' contributions — — 129 116 Actuarial loss (gain) (4,585 ) 5,100 (17,983 ) (2,670 ) Plan amendments — — 372 432 Benefits paid (10,730 ) (10,822 ) (9,428 ) (6,583 ) Settlements (143,389 ) — (784 ) — Foreign exchange and other — — (13,491 ) 22,644 Benefit obligation, ending $ 2,230 $ 156,729 $ 208,818 $ 240,749 Change in plan assets: Fair value of plan assets, beginning $ 160,988 $ 155,638 $ 226,512 $ 196,818 Employer and plan participant contributions 1,697 260 5,648 4,990 Return on plan assets (8,565 ) 15,912 (6,720 ) 9,955 Benefits paid (10,730 ) (10,822 ) (9,428 ) (6,583 ) Settlements (143,390 ) — (784 ) — Foreign exchange and other — — (11,848 ) 21,332 Fair value of plan assets, ending $ — $ 160,988 $ 203,380 $ 226,512 Funded status, net liability or (net asset) $ 2,230 $ (4,259 ) $ 5,438 $ 14,237 The following table presents the balance sheet location of the Company's pension liabilities and assets: December 31, U.S. Plans Non-U.S. Plans 2018 2017 2018 2017 Other accrued liabilities $ (260 ) $ (260 ) $ (281 ) $ (1,235 ) Pension and other postretirement benefit liabilities (1,970 ) (2,152 ) (11,329 ) (18,176 ) Other noncurrent assets — 6,671 6,172 5,174 The Company terminated a significant U.S. defined benefit pension plan in the fourth quarter of 2018 through the purchase of annuities. The Company contributed $1.4 million to the plan during the year ended December 31, 2018, which was needed to fund the termination of the plan. Upon termination, the Company recognized a pretax charge in other expense, net, of $34.5 million primarily related to unrecognized net actuarial losses previously recorded in accumulated other comprehensive loss. The accumulated benefit obligation for the Company’s U.S. defined benefit pension plans was $2,230 and $156,729 as of December 31, 2018 and 2017, respectively and the accumulated benefit obligation for the Company’s non-U.S. defined benefit pension plans was $174,588 and $195,922 as of December 31, 2018 and 2017, respectively. The following table summarizes information for the Company’s pension plans with an accumulated benefit obligation in excess of plan assets: December 31, U.S. Plans Non-U.S. Plans 2018 2017 2018 2017 Projected benefit obligation $ 2,230 $ 2,412 $ 13,053 $ 16,755 Accumulated benefit obligation 2,230 2,412 11,546 14,683 Fair value of plan assets — — 3,760 4,034 The following table summarizes pretax amounts included in accumulated other comprehensive loss: December 31, U.S. Plans Non-U.S. Plans 2018 2017 2018 2017 Unrecognized net actuarial loss $ (415 ) $ (26,261 ) $ (22,784 ) $ (28,410 ) Unrecognized prior service cost — — (748 ) (437 ) Total $ (415 ) $ (26,261 ) $ (23,532 ) $ (28,847 ) Actuarial gains and losses are amortized using a corridor approach. The corridor is equal to 10% of the greater of the benefit obligation and the fair value of the assets. Gains and losses in excess of the corridor are generally amortized over the average remaining life of the plan participants. Pretax amounts for net periodic benefit cost and other amounts included in other comprehensive income (loss) for the defined benefit pension plans consisted of the following components: Year Ended December 31, U.S. Plans Non-U.S. Plans 2018 2017 2016 2018 2017 2016 Service cost $ — $ — $ — $ 4,097 $ 4,876 $ 5,352 Interest cost 4,205 5,929 6,452 5,157 5,300 6,096 Recognized actuarial loss 388 664 923 1,298 1,523 116 Expected return on plan assets (5,058 ) (6,769 ) (7,002 ) (7,686 ) (7,598 ) (8,632 ) Settlement loss 34,495 — — 15 — — Net periodic benefit cost (income) 34,030 (176 ) 373 2,881 4,101 2,932 Changes in plan assets and benefit obligations included in other comprehensive income (loss): Change in unrecognized net actuarial loss (gain) 8,649 (4,707 ) (6,540 ) (5,626 ) (4,001 ) 23,750 Change in unrecognized prior service cost — — — 311 437 — Settlement (34,495 ) — — — — — Total included in other comprehensive income (loss) (25,846 ) (4,707 ) (6,540 ) (5,315 ) (3,564 ) 23,750 Total recognized in net periodic benefit cost and included in other comprehensive income (loss) $ 8,184 $ (4,883 ) $ (6,167 ) $ (2,434 ) $ 537 $ 26,682 Assumptions Significant weighted average assumptions used in determining benefit obligations and net periodic benefit cost are as follows: U.S. Plans Non-U.S. Plans 2018 2017 2016 2018 2017 2016 Benefit obligations: Discount rate 3.70 % 3.50 % 3.94 % 2.50 % 2.23 % 2.38 % Rate of compensation increase — % — % — % 3.92 % 3.92 % 4.04 % Net periodic benefit cost: Discount rate 3.50 % 3.94 % 4.19 % 2.23 % 2.38 % 3.52 % Rate of return on plan assets — % 4.10 % 4.50 % 3.41 % 3.49 % 3.71 % Rate of compensation increase — % — % — % 3.92 % 4.04 % 4.18 % The Company considered the available yields on high-quality fixed-income investments with maturities corresponding to the Company’s expected benefit obligations to determine the discount rates at each measurement date. Plan Assets In developing the expected rate of return on plan assets, the Company considered the expected long-term rate of return on individual asset classes. Expected return on plan assets is based on the market value of the assets. A portion of the non-U.S. pension assets are managed by independent investment advisors with an objective of transitioning to a portfolio of fixed income and absolute return investments that matches the durations of the obligations as the funded status of each plan improves. The absolute return investment fund is a diversified portfolio designed to achieve long-term total returns. The remainder of the non-U.S. pension assets is invested with the objective of maximizing return. Mutual funds classified as Level 1 are valued at net asset value, which is based on the fair value of the funds’ underlying securities. Certain mutual funds are classified as Level 2 because a portion of the funds’ underlying assets are valued using significant other observable inputs. Other assets are primarily composed of fixed income investments (including insurance and real estate products) and are valued based on the investment’s stated rate of return, which approximates market interest rates. The Company had no U.S. defined benefit pension plan assets as of December 31, 2018. The estimated fair values and the valuation input levels of the Company’s non-U.S. defined benefit pension plan assets are as follows: December 31, 2018 Non-U.S. Plans Level 1 Fair Value Level 2 Fair Value Mutual funds: International equity $ 22,607 $ 25,503 International debt 36,142 82,429 Absolute return — 26,168 Other 2,858 7,673 Total $ 61,607 $ 141,773 The estimated fair values and the valuation input levels of the Company’s plan assets are as follows: December 31, 2017 U.S. Plans Non-U.S. Plans Level 1 Fair Value Level 2 Fair Value Level 1 Fair Value Level 2 Fair Value Mutual funds: U.S. equity $ 257 $ — $ — $ — International equity 1,934 — 34,704 26,781 U.S. debt 145,967 — — — International debt 10,252 — 31,192 98,789 Absolute return — — — 21,994 Other 2,578 — 6,645 6,407 Total $ 160,988 $ — $ 72,541 $ 153,971 Expected Cash Flows The Company expects to contribute $0.3 million to U.S defined benefit pension plans and $4.7 million to non-U.S. defined benefit pension plans during 2019. The following table summarizes projected benefit payments from pension plans through 2028, including benefits attributable to estimated future service (in millions): U.S. Plans Non-U.S. Plans 2019 $ 0.3 $ 9.4 2020 0.3 8.1 2021 0.3 8.9 2022 0.3 9.1 2023 0.3 9.3 2024-2028 1.3 65.2 Other Postretirement Benefit Plans The Company sponsors postretirement health care and life insurance benefit plans that provide benefits to certain former U.S. employees and certain U.S. full-time employees who retire from the Company. The health care plans contain various cost-sharing features such as participant contributions, deductibles, coinsurance and caps, with Medicare as the primary provider of health care benefits for eligible retirees. The Company amended certain of the plans to terminate benefits as of December 31, 2018 and recognized a pre-tax gain of $9.7 million in other expense, net, primarily related to the reclassification of unrecognized prior service credits and unrecognized net actuarial gains from accumulated other comprehensive loss. The accounting for the remainder of the health care plans anticipates future cost-sharing changes that are consistent with the Company’s expressed intent to maintain a consistent level of cost sharing or capped benefits with retirees. There are no plan assets associated with these post-retirement health care and life insurance benefit plans. The benefit obligation for the remaining plans was $4.2 million and $5.7 million as of December 31, 2018 and 2017, respectively, primarily recorded in pension and other postretirement liabilities on the Consolidated Balance Sheets. The pretax gains recognized in accumulated other comprehensive loss were $3.1 million and $18.7 million for the years ended December 31, 2018 and 2017, respectively, mostly related to unrecognized prior service credits. The net periodic benefit income of $7.4 million (excluding the gain discussed above related to the termination of certain benefits), $4.7 million and $5.1 million for the years ended December 31, 2018, 2017 and 2016, respectively, resulted primarily from the amortization of net actuarial gains and prior service credits.

Income Taxes	11. INCOME TAXES On December 22, 2017, the U.S. government enacted tax reform legislation (U.S. tax reform) 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 SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118) to provide companies with transitional relief. Specifically, SAB 118 provided up to one year from the date of enactment for companies to finalize the accounting for the effects of this new legislation.

The deferred tax asset for state net operating loss and tax credit carryforwards as of December 31, 2018 includes state net operating loss carryforwards (net of federal tax impact) of $17.2 million, which begin to expire in 2019, and state tax credit carryforwards (net of federal tax impact) of $1.3 million which begin to expire in 2019. A valuation allowance of $14.9 million has been established against these and other state income tax related deferred tax assets. The deferred tax assets for foreign net operating loss and tax credit carryforwards as of December 31, 2018 includes foreign net operating loss carryforwards (net of federal tax effects) of $74.7 million, which will begin to expire in 2019, and foreign tax credit carryforwards (net of federal tax effects) of $11.1 million, which begin to expire in 2023. Certain of these foreign net operating loss carryforwards are subject to local restrictions limiting their utilization. Valuation allowances of $63.0 million have been established related to these foreign deferred tax assets. In addition to the valuation allowances detailed above, the Company has also established a valuation allowance of $7.2 million against other deferred tax assets. Following enactment of U.S. tax reform and the associated one-time transition tax, in general, repatriation of foreign earnings to the U.S. can be completed with no incremental U.S. tax. However, repatriation of foreign earnings could subject the Company to U.S. state and non-U.S. jurisdictional taxes (including withholding taxes) on distributions. The following table reflects a reconciliation of the beginning and end of period amounts of gross unrecognized tax benefits, excluding interest and penalties: Year Ended December 31, 2018 2017 2016 Balance at beginning of period $ 46,635 $ 48,312 $ 64,085 Increase related to prior periods 3,993 9,076 742 Decrease related to prior periods (691 ) (722 ) (3,416 ) Increase related to current periods — 1,117 — Decrease related to settlements with taxing authorities (3,930 ) (764 ) (22 ) Decrease related to lapse in statutes of limitations (25,936 ) (10,384 ) (16,758 ) Increase related to acquisition — — 3,681 Balance at end of period $ 20,071 $ 46,635 $ 48,312 The Company’s liability for unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate in future periods was $13.0 million as of December 31, 2018. The Company operates in numerous jurisdictions worldwide and is subject to routine tax audits on a regular basis. The determination of the Company’s unrecognized tax benefits involves significant management judgment regarding interpretation of relevant facts and tax laws in each of these jurisdictions. Unrecognized tax benefits are reviewed and evaluated on an ongoing basis and may be adjusted for changing facts and circumstances including the lapse of applicable statutes of limitation and closure of tax examinations. Although the timing and outcome of such events are difficult to predict, the Company estimates that the balance of unrecognized tax benefits, excluding the impact of accrued interest and penalties, may be reduced by up to $5.0 million within the next twelve months. The Company provides for interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2018 and 2017, the Company had accrued $5.2 million and $9.0 million, respectively, for interest and penalties. During the years ended December 31, 2018, 2017 and 2016 the net expense (benefit) for interest and penalties recognized through income tax expense was $(3.8) million, $0.1 million and $0.4 million, respectively. The Company files federal, state and local tax returns with statutes of limitation generally ranging from 3 to 4 years. The Company is generally no longer subject to federal tax examinations for years prior to 2015 or state and local tax examinations for years prior to 2014. Tax returns filed by the Company’s significant foreign subsidiaries are generally subject to statutes of limitations of 3 to 7 years and are generally no longer subject to examination for years prior to 2013. In many jurisdictions, tax authorities retain the ability to review prior years’ tax returns and to adjust any net operating loss or tax credit carryforwards from these years that are available to be utilized in subsequent periods. During 2018, the Company recognized $29.9 million related to the lapse of applicable statutes of limitations and the conclusion of various domestic and foreign examinations.

Equity [Abstract]
Stockholders' Equity	12. STOCKHOLDERS’ EQUITY Stock Repurchase Program During the year ended December 31, 2017, the Company repurchased 4.8 million shares of its outstanding common stock at an average cost of $36.50 per share. The Company did not repurchase any of its common stock during the year ended December 31, 2018. Equity-Based Compensation Plans The Company’s Board of Directors approved the 2013 Long Term Incentive Plan (the 2013 Plan), effective October 24, 2013, authorizing 18.6 million shares for issuance. Awards under the 2013 Plan may include stock, stock options, restricted stock, restricted stock units (RSUs), performance units, performance share units (PSUs), performance-based restricted stock, stock appreciation rights and dividend equivalent rights for employees and non-employee directors of the Company. Approval of the 2013 Plan canceled all shares authorized but not issued under predecessor plans. Awards granted prior to October 24, 2013 remain subject to the provisions of the predecessor plans. As of December 31, 2018, 10.6 million shares were available for future grants under the 2013 Plan. As of December 31, 2018, $54.4 million of total unrecognized compensation expense related to non-vested stock options, RSUs and PSUs is expected to be recognized over a remaining weighted average period of 1.4 years. There were no significant capitalized equity-based compensation costs at December 31, 2018. The following table shows a summary of the equity-based compensation expense included in the Consolidated Statements of Operations and Comprehensive Income: Year Ended December 31, 2018 2017 2016 Selling, general and administrative $ 34,206 $ 31,879 $ 26,709 Cost of sales 5,681 5,297 4,665 Research and development 5,012 4,674 3,632 Total equity-based compensation expense $ 44,899 $ 41,850 $ 35,006 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 as of December 31, 2017 4,830 $ 13.01 Granted 482 $ 38.34 Exercised (570 ) $ 10.75 Forfeited (90 ) $ 34.09 Options outstanding as of December 31, 2018 4,652 $ 15.51 3.9 $ 31,467 Options vested at December 31, 2018 3,838 $ 10.98 2.8 $ 31,467 Options unvested at December 31, 2018 814 $ 36.84 8.6 $ — The total intrinsic value of options exercised during the years ended December 31, 2018, 2017 and 2016 was $12.7 million, $31.2 million and $50.6 million, respectively. The exercise prices of outstanding options at December 31, 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 2,498 1.9 $ 5.42 2,498 $ 5.42 $5.75 to $22.99 523 1.4 $ 8.59 523 $ 8.59 $23.00 to $42.32 1,631 7.7 $ 33.16 817 $ 29.49 $2.96 to $42.32 4,652 3.9 $ 15.51 3,838 $ 10.98 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 a share 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 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: Year Ended December 31, 2018 2017 2016 Expected option term (in years) 6.0 6.0 6.0 Risk-free interest rate 2.7 % 2.0 % 1.4 % Expected volatility 35.0 % 40.0 % 50.0 % Weighted average exercise price $ 38.34 $ 38.00 $ 25.08 Weighted average fair value at grant date $ 14.83 $ 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 share units at December 31, 2017 2,279 $ 31.83 Granted 1,131 $ 37.87 Vested and shares issued (1,105 ) $ 30.82 Forfeited (269 ) $ 34.13 Non-vested share units at December 31, 2018 2,036 $ 35.43 The weighted average grant date fair value per unit of these awards granted during the years ended December 31, 2018, 2017 and 2016 was $37.87, $37.90 and $24.93, respectively. The total fair value of RSUs that vested during the years ended December 31, 2018, 2017 and 2016 was $42.1 million, $42.9 million and $13.6 million, respectively. 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. Over the performance period, the number of shares that are expected to be issued is adjusted upward or downward based upon the probable achievement of performance targets. 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. For PSUs granted in 2018 that had a 2018 earnings-based performance measure, the performance was below target resulting in a negative share performance adjustment. 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 share units at December 31, 2017 344 $ 26.75 Granted 187 $ 38.34 Vested and shares issued (203 ) $ 26.80 Forfeited (32 ) $ 26.41 Performance adjustment (34 ) $ 38.34 Non-vested share units at December 31, 2018 262 $ 33.52 The weighted average grant date fair value per unit of these awards granted during the years ended December 31, 2018, 2017 and 2016 was $38.34, $38.00 and $25.05, respectively. The total fair value of PSUs that vested during the years ended December 31, 2018 and 2017 was $7.9 million and $2.4 million, respectively. No PSUs vested during the year ended December 31, 2016.

SUBSEQUENT EVENTS On November 8, 2018, the Company announced an agreement to acquire ARRIS International plc (ARRIS) in an all cash transaction with a total purchase price of approximately $7.4 billion, or $31.75 per share. To fund the acquisition of ARRIS, on February 19, 2019, the Company issued $1.25 billion of 5.50% senior secured notes due 2024, $1.5 billion of 6.00% senior secured notes due 2026 and $1.0 billion of 8.25% senior unsecured notes due 2027 and priced the borrowing of $3.2 billion under a new senior secured term loan due 2026 with an interest rate of LIBOR plus 3.25%. The proceeds of the notes were placed into escrow and will be released upon consummation of the acquisition, and it is expected that the new senior secured term loan will be borrowed at closing of the acquisition. The Company expects to use a portion of the new senior secured term loan to pay off its existing senior secured term loan due December 2022. The Company also expects to enter into a new asset-based revolving credit facility in an amount of up to $1.0 billion, subject to borrowing base capacity.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation The accompanying consolidated financial statements include CommScope Holding Company, Inc., along with its direct and indirect subsidiaries. All intercompany accounts and transactions are eliminated in consolidation. Prior to January 1, 2017, the Company consolidated the operating results of the Broadband Network Solutions (BNS) business acquired from TE Connectivity 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 52 weeks for the year ended December 31, 2017 compared to 53 weeks for the year ended December 31, 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, and therefore, reported the cumulative effect of the change in accounting principle in net income for the year ended December 31, 2017. Certain prior year amounts have been reclassified to conform to the current year presentation.
Use of Estimates in the Preparation of the Financial Statements	Use of Estimates in the Preparation of the Financial Statements The preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and their underlying assumptions form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other objective sources. The Company bases its estimates on historical experience and 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. Significant accounting estimates reflected in the Company’s financial statements include the allowance for doubtful accounts; reserves for sales returns, discounts, allowances, rebates and distributor price protection programs; inventory excess and obsolescence reserves; product warranty reserves and other contingent liabilities; tax valuation allowances; liabilities for unrecognized tax benefits; purchase price allocations; impairment reviews for investments, fixed assets, goodwill and other intangibles; and pension and other postretirement benefit costs and liabilities. Although these estimates are based on management’s knowledge of and experience with past and current events and on management’s assumptions about future events, it is at least reasonably possible that they may ultimately differ materially from actual results.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents represent deposits in banks and cash invested temporarily in various instruments with a maturity of three months or less at the time of purchase.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are stated at the amount owed by the customer, net of allowances for estimated doubtful accounts, discounts, returns and rebates. The Company maintains
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value. Inventory cost is determined on a first-in, first-out (FIFO) basis. Costs such as idle facility expense, excessive scrap and re-handling costs are expensed as incurred. The Company maintains reserves to reduce the value of inventory to the lower of cost or net realizable value, including reserves for excess and obsolete inventory.
Long-Lived Assets	Long-Lived Assets Property, Plant and Equipment Property, plant and equipment are stated at cost. Upon application of acquisition accounting, property, plant and equipment are measured at estimated fair value as of the acquisition date to establish a new historical cost basis. Provisions for depreciation are based on estimated useful lives of the assets using the straight-line method. Useful lives generally range from 10 to 35 years for buildings and improvements and 3 to 10 years for machinery and equipment. Expenditures for repairs and maintenance are expensed as incurred. Assets that management intends to dispose of and that meet held for sale criteria are carried at the lower of the carrying value or fair value less costs to sell. Goodwill and Other Intangible Assets Goodwill is assigned to reporting units based on the difference between the purchase price as allocated to the reporting units and the estimated fair value of the identified net assets acquired as allocated to the reporting units. Purchased intangible assets with finite lives are carried at their estimated fair values at the time of acquisition less accumulated amortization and any impairment charges. Amortization is recognized on a straight-line basis over the estimated useful lives of the respective assets (see Note 4). 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. 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. See Notes 4 and 8 for discussion of impairment charges. Due to uncertain market conditions, it is possible that future impairment reviews may indicate additional impairments of goodwill, other intangible assets and/or property, plant and equipment, which could result in charges that are material to the Company’s results of operations.
Income Taxes	Income Taxes Deferred income taxes reflect the future tax consequences of differences between the financial reporting and tax basis of assets and liabilities. The Company records a valuation allowance, when appropriate, to reduce deferred tax assets to an amount that is more likely than not to be realized. Tax benefits that result from uncertain tax positions may be recognized only if they are considered more likely than not to be sustainable, based on their technical merits. The amount of benefit to be recognized is the largest amount of tax benefit that is at least 50% likely to be realized. In addition, the Company does not provide for U.S. taxes related to the foreign currency remeasurement gains and losses on its long-term intercompany loans with foreign subsidiaries. These loans are not expected to be repaid in the foreseeable future, and the foreign currency gains and losses are therefore recorded to accumulated other comprehensive loss.
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. The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset would be one year or less. 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. The Company includes shipping and handling costs billed to customers in net sales and includes the costs incurred to transport product to customers as cost of sales. Shipping and handling costs incurred after control is transferred to the customer are accounted for as fulfillment costs and are not accounted for as separate revenue obligations. Certain internal handling costs, which relate to activities to prepare goods for shipment, are recorded in selling, general and administrative expense and were $55.0 million, $62.1 million and $56.2 million for the years ended December 31, 2018, 2017 and 2016, respectively.
Taxes Collected from Customers	Tax Collected from Customers Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, which are collected by the Company from customers, are excluded from revenue.
Product Warranties	Product Warranties The Company recognizes a liability for the estimated claims that may be paid under its customer assurance-type 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.
Advertising Costs	Advertising Costs Advertising costs are expensed in the period in which they are incurred. Advertising expense was $17.3 million, $21.2 million and $20.0 million for the years ended December 31, 2018, 2017 and 2016, respectively.
Research and Development	Research and Development Research and development (R&D) costs are expensed in the period in which they are incurred. R&D costs include materials and equipment that have no alternative future use, depreciation on equipment and facilities currently used for R&D purposes, personnel costs, contract services and reasonable allocations of indirect costs, if clearly related to an R&D activity. Expenditures in the pre-production phase of an R&D project are recorded as R&D expense. However, costs incurred in the pre-production phase that are associated with output actually used in production are recorded in cost of sales. A project is considered finished with pre-production efforts when management determines that it has achieved acceptable levels of scrap and yield, which vary by project. Expenditures related to ongoing production are recorded in cost of sales.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities CommScope is exposed to risks resulting from adverse fluctuations in commodity prices, interest rates and foreign currency exchange rates. CommScope’s risk management strategy includes the use of derivative financial instruments whenever management determines their use to be reasonable and practical. This strategy does not permit the use of derivative financial instruments for trading or speculation. Derivative contracts not designated as hedging instruments are measured at fair value and are marked to market each period through earnings. During 2017, the Company began a hedging strategy to designate certain foreign exchange forward contracts as net investment hedges to mitigate a portion of the foreign currency risk on the euro net investment in a foreign subsidiary. 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 designated forward contracts. For hedges that meet the effectiveness requirements, changes in fair value are recorded as a component of other comprehensive income (loss), net of tax. The Company did not designate any transactions as hedges in the year ended December 31, 2016. 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 interest expense over the life of each contract. See Note 7 for further disclosure related to the derivative instruments and hedging activities. The Company has elected and documented the use of the normal purchases and sales exception for normal purchase and sales contracts that meet the definition of a derivative financial instrument.
Foreign Currency Translation	Foreign Currency Translation For the years ended December 31, 2018, 2017 and 2016, approximately 44%, 46% and 46%, respectively, of the Company’s net sales were to customers located outside the U.S. A portion of these sales were denominated in currencies other than the U.S. dollar, particularly sales from the Company’s foreign subsidiaries. The financial position and results of operations of certain of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Revenues and expenses of these subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities of these subsidiaries have been translated at the exchange rates as of the balance sheet date. Translation gains and losses are recorded in accumulated other comprehensive loss. Upon sale or liquidation of an investment in a foreign subsidiary, the amount of net translation gains or losses that have been accumulated in other comprehensive loss attributable to that investment are reported as a gain or loss in earnings in the period in which the sale or liquidation occurs. During the year ended December 31, 2018, the Company liquidated a foreign subsidiary and recognized $14.0 million in translation losses in other expense, net that had been in accumulated other comprehensive loss. Aggregate foreign currency gains and losses, such as those resulting from the settlement of receivables or payables, foreign currency contracts and short-term intercompany advances in a currency other than the subsidiary’s functional currency, are recorded currently in earnings (included in other expense, net) and resulted in losses of $15.9 million, $8.7 million and $9.5 million during the years ended December 31, 2018, 2017 and 2016, respectively. Foreign currency remeasurement gains and losses related to certain long-term intercompany loans that are not expected to be settled in the foreseeable future and the effective portion of foreign currency contracts designated as net investment hedges are recorded in accumulated other comprehensive loss. See Note 7 for disclosure of foreign currency gains and losses specifically related to foreign currency contracts.
Equity-Based Compensation	Equity-Based Compensation The estimated fair value of stock awards is recognized as expense over the requisite service periods. Forfeitures of stock awards are recognized as they occur. The Company records deferred tax assets related to compensation expense for awards that are expected to result in future tax deductions for the Company, based on the amount of compensation cost recognized and the Company’s statutory tax rate in the jurisdiction in which it expects to receive a deduction. Differences between the deferred tax assets recognized for financial reporting purposes and actual tax deductions reported on the Company’s income tax return are recorded in the Consolidated Statements of Operations and Comprehensive Income within income tax expense.
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 dilutive effect of potential common shares outstanding during the period using the treasury stock method. Dilutive potential 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 condition was not met (2.1 million, 1.5 million and 1.0 million shares for the years ended December 31, 2018, 2017 and 2016, respectively). The following table presents the basis for the earnings per share computations: Year Ended December 31, 2018 2017 2016 Numerator: Net income for basic and diluted earnings per share $ 140,217 $ 193,764 $ 222,838 Denominator: Weighted average common shares outstanding - basic 192,022 192,430 192,470 Dilutive effect of equity-based awards 3,310 4,381 3,989 Weighted average common shares outstanding - diluted 195,332 196,811 196,459 Earnings per share: Basic $ 0.73 $ 1.01 $ 1.16 Diluted $ 0.72 $ 0.98 $ 1.13
Business Combinations	Business Combinations The Company uses the acquisition method of accounting for business combinations which requires the allocation of the acquisition date fair value to the underlying tangible and intangible assets acquired and liabilities assumed based on their respective fair market value. Goodwill represents the excess of the consideration transferred over the fair value of the net assets acquired. The fair values of the assets acquired and liabilities assumed are determined based upon the Company’s valuation and involves making significant estimates and assumptions based on facts and circumstances that existed as of the acquisition date. The Company uses a measurement period following the acquisition date to gather information that existed as of the acquisition date that is needed to determine the fair value of the assets acquired and liabilities assumed. The measurement period ends once all information is obtained, but no later than one year from the acquisition date.
Concentrations of Risk	Concentrations of Risk Non-derivative financial instruments used by the Company in the normal course of business include letters of credit and commitments to extend credit, primarily accounts receivable. The Company generally does not require collateral on its accounts receivable. These financial instruments involve risk, including the credit risk of nonperformance by the counterparties to those instruments, and the actual loss may exceed the reserves provided in the Company’s balance sheet. See Note 14 for further discussion of customer-related concentrations of risk. The Company manages its exposures to credit risk associated with accounts receivable using such tools as credit approvals, credit limits and monitoring procedures. CommScope estimates the allowance for doubtful accounts based on the actual payment history and individual circumstances of significant customers as well as the age of receivables. In management’s opinion, as of December 31, 2018, the Company did not have significant unreserved risk of credit loss due to the non-performance of customers or other counterparties related to amounts receivable. However, an adverse change in financial condition of a significant customer or group of customers or in the telecommunications industry could materially affect the Company’s estimates related to doubtful accounts. The principal raw materials purchased by CommScope (aluminum, bimetals, copper, optical fiber, plastics and other polymers and steel) are subject to changes in market price as these materials are linked to various commodity markets. The Company attempts to mitigate these risks through effective requirements planning and by working closely with its key suppliers to obtain the best possible pricing and delivery terms.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted in 2018 In the fourth quarter of 2018, the Company early adopted ASU No. 2018-14, Disclosure Framework: Changes to the Disclosure Requirements for Defined Benefit Plans, In the fourth quarter of 2018, the Company early adopted ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income 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 years ended December 31, 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 Consolidated Balance Sheets. This adjustment reflects an acceleration of $8.0 million of net sales. The impact of adoption of the new revenue recognition standard on the consolidated financial statements was as follows: Year Ended December 31, 2018 As Reported Amounts Without Adoption of ASU No. 2014-09 Effect of Change Increase / (Decrease) Net sales $ 4,568,507 $ 4,572,634 $ (4,127 ) Cost of sales 2,880,223 2,881,920 (1,697 ) Operating income 449,968 452,398 (2,430 ) Income tax expense 30,495 31,117 (622 ) Net income 140,217 142,025 (1,808 ) As of December 31, 2018 As Reported Amounts Without Adoption of ASU No. 2014-09 Effect of Change Increase / (Decrease) Assets: Accounts receivable, less allowance for doubtful accounts $ 810,359 $ 808,381 $ 1,978 Inventories, net 473,327 475,008 (1,681 ) Liabilities: Other accrued liabilities 291,385 292,693 (1,308 ) Stockholders' equity: Retained earnings (accumulated deficit) (249,777 ) (251,382 ) 1,605 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 August 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement (CCA) that is a Service Contract, 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
