Background and Description of the Business	1. BACKGROUND AND DESCRIPTION OF THE BUSINESS CommScope Holding Company, Inc., along with its direct and indirect subsidiaries (CommScope or the Company), is a global provider of infrastructure solutions for the core, access and edge layers of communication networks. The Company’s solutions and services for wired and wireless networks enable high-bandwidth data, video and voice applications. CommScope’s global leadership position is built upon innovative technology, broad solution offerings, high-quality and cost-effective customer solutions and global manufacturing and distribution scale. On August 28, 2015, the Company acquired TE Connectivity’s Broadband Network Solutions business (BNS) in an all-cash transaction valued at approximately $3.0 billion. See Note 3 for additional discussion of the BNS acquisition. As of January 1, 2016, the Company reorganized its internal management and reporting structure as part of the integration of the BNS acquisition. The reorganization changed the information regularly reviewed by the Company’s chief operating decision maker for purposes of allocating resources and assessing performance. As a result, the Company is reporting financial performance for 2016 based on its new operating segments: CommScope Connectivity Solutions (CCS) and CommScope Mobility Solutions (CMS). Both CCS and CMS represent non-aggregated reportable operating segments. Prior to this change, the Company operated and reported the following operating segments: Wireless, Enterprise, Broadband and BNS. All prior year amounts in these consolidated financial statements have been recast to reflect these operating segment changes. As of December 31, 2015, funds affiliated with The Carlyle Group (Carlyle) owned 32.0% of the outstanding shares of CommScope. During the year ended December 31, 2016, Carlyle sold its remaining shares and no longer holds any stock in CommScope.

Summary of Significant Accounting Policies	CommScope Holding Company, Inc. Notes to Consolidated Financial Statements (In thousands, unless otherwise noted) 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. The BNS acquisition was accounted for using the acquisition method of accounting. The results of the BNS business are reported in the Company’s consolidated financial statements from August 28, 2015 to December 25, 2015 for the year ended December 31, 2015 and from December 26, 2015 to December 30, 2016 for the year ended December 31, 2016. The BNS fiscal calendar included 53 weeks in 2016. Certain prior year amounts have been reclassified to conform to the current year presentation. 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, which are operating segments or one level below the operating segment level, 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. Goodwill impairment charges of $15.3 million, $74.4 million and $4.9 million were recorded during the years ended December 31, 2016, 2015 and 2014, respectively. See Notes 4 and 8 for further discussion of these impairment charges. Property, plant and equipment and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, based on the undiscounted cash flows expected to be derived from the use and ultimate disposition of the assets. Assets identified as impaired are carried at estimated fair value. During the years ended December 31, 2016, 2015 and 2014, the Company recognized pretax impairment charges for long-lived assets, other than goodwill impairments, of $23.3 million, $5.5 million and $7.2 million, respectively. See Notes 4 and 8 for further discussion of these impairment charges. During the year ended December 31, 2015, the Company determined that a note receivable related to a previous divestiture was likely impaired and recorded a $10.9 million impairment charge. Due to uncertain market conditions, it is possible that future impairment reviews may indicate additional impairments of goodwill and/or other intangible assets, 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. The cumulative amount of undistributed earnings from foreign subsidiaries for which no U.S. taxes have been provided was $606.1 million as of December 31, 2016. 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 is recognized when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the selling price is fixed or determinable and collectability is reasonably assured. The majority of the Company’s revenue comes from product sales. Revenue from product sales is recognized when the risks and rewards of ownership have passed to the customer and revenue is measurable. Revenue is not recognized related to product sold to contract manufacturers that the Company anticipates repurchasing in order to complete the sale to the ultimate customer. Revenue for certain of the Company’s products is derived from multiple-element contracts. The value of the revenue elements within these contracts is allocated based on the relative selling price of each element. The relative selling price is determined using vendor-specific objective evidence of selling price or other third party evidence of selling price, if available. If these forms of evidence are unavailable, revenue is allocated among elements based on management’s best estimate of the stand-alone selling price of each element. Revenue is generally recognized upon acceptance by the customer. For sales to distributors, system integrators and value-added resellers (primarily for the CCS segment), revenue is recorded at the net amount to be received after deductions for estimated discounts, allowances, 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 are recorded when circumstances indicate revisions may be necessary. If management does not have sufficient historical experience to make a reasonable estimation of these reductions to revenue, recognition of the revenue is deferred until management believes there is a sufficient basis to recognize such revenue. Product Warranties The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material. Shipping and Handling Costs CommScope 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. Certain internal handling costs, which relate to activities to prepare goods for shipment, are recorded in selling, general and administrative expense and were approximately $56.2 million, $29.3 million and $27.2 million for the years ended December 31, 2016, 2015 and 2014, respectively. Advertising Costs Advertising costs are expensed in the period in which they are incurred. Advertising expense was $20.0 million, $13.6 million and $10.5 million for the years ended December 31, 2016, 2015 and 2014, 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, such as forward contracts, options, cross currency swaps, certain interest rate swaps, caps and floors and non-derivative financial instruments, such as foreign-currency-denominated loans, as hedges of these risks, 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. The Company did not designate any transactions as hedges in the years ended December 31, 2016, 2015 or 2014. Derivative contracts are measured at fair value and are marked to market each period through earnings. As such, there were no unrecognized gains or losses as of December 31, 2016 or 2015. 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, 2016, 2015 and 2014, approximately 46%, 51% and 45%, respectively, of the Company’s net sales were to customers located outside the United States (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 to 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 $9.5 million, $15.1 million and $2.7 million during the years ended December 31, 2016, 2015 and 2014, 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 are recorded to 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 that are ultimately expected to vest is recognized as expense over the requisite service periods. 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 additional paid-in capital (if the tax deduction exceeds the deferred tax asset) or in the Consolidated Statements of Operations and Comprehensive Income (Loss) as additional income tax expense (if the deferred tax asset exceeds the tax deduction and no excess additional paid-in capital exists from previous awards). Earnings (Loss) Per Share Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is based on net income (loss) 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 (loss) per share because the effect was either antidilutive or the performance condition was not met (1.0 million, 5.9 million and 1.4 million shares for the years ended December 31, 2016, 2015 and 2014, respectively). Antidilutive securities for the year ended December 31, 2015 included 4.3 million shares of equity-based awards which would have been considered dilutive if the Company had not been in a net loss position. The following table presents the basis for the earnings (loss) per share computations: Year Ended December 31, 2016 2015 2014 Numerator: Net income (loss) for basic and diluted earnings (loss) per share $ 222,838 $ (70,875 ) $ 236,772 Denominator: Weighted average common shares outstanding - basic 192,470 189,876 186,905 Dilutive effect of equity-based awards 3,989 — 4,545 Weighted average common shares outstanding - diluted 196,459 189,876 191,450 Earnings (loss) per share: Basic $ 1.16 $ (0.37 ) $ 1.27 Diluted $ 1.13 $ (0.37 ) $ 1.24 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 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 and 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. Business Combinations The Company uses the acquisition method of accounting for business combinations which requires assets acquired and liabilities assumed to be recognized at their fair values on the acquisition date. Goodwill represents the excess of the purchase price 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 maximum potential 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, 2016, the Company did not have significant unreserved risk of credit loss due to the nonperformance 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 (copper, aluminum, steel, plastics and other polymers, bimetals and optical fiber) 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 2016 During the fourth quarter of 2016, the Company prospectively adopted Accounting Standards Update (ASU) No. 2015-11, Simplifying the Measurement of Inventory Issued but Not Adopted In August 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-15, Cash Flow Classification of Certain Cash Receipts and Cash Payments In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting In February 2016, the FASB issued ASU No. 2016-02, Leases Leases. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers During 2016, the Company completed an impact assessment and determined that adoption of the standard will likely result in changes to revenue recognition related to the timing of when revenues are recognized for contracts containing both product and service obligations. These contract revenues are currently accounted for using the multi-element guidance and are primarily for metro cell, DAS and small cell solutions within the CMS segment. Due to the short-term nature of these contracts, the ultimate impact to the Company’s consolidated financial statements will be based on customer-specific contract terms in effect at adoption, and could be material. The Company believes that changes to its accounting policies, processes, internal controls and information systems will be required to comply with this update. The Company is in the process of implementing the changes necessary to meet the standard update’s reporting and disclosure requirements. 1

Business Combinations [Abstract]
Acquisitions	3. ACQUISITIONS Broadband Network Solutions On August 28, 2015, the Company acquired TE Connectivity’s BNS business for approximately $3.0 billion in an all-cash transaction. Net sales of $1,770.3 million and $529.6 million related to the acquired business are reflected in the Consolidated Statements of Operations and Comprehensive Income (Loss) for the years ended December 31, 2016 and 2015, respectively, and are primarily reported in the CCS segment. The purchase price for BNS was assigned to assets acquired and liabilities assumed based on their estimated fair values as of the date of acquisition and the excess was allocated to goodwill. The following table summarizes the preliminary allocation of the purchase price at the date of acquisition and the subsequent measurement period adjustments to arrive at the final allocation of the purchase price at the acquisition date (in millions): Amounts Recognized as of Acquisition Date Measurement Period Adjustments Amounts Recognized as of Acquisition Date (as adjusted) Cash and cash equivalents $ 63.7 $ — $ 63.7 Accounts receivable 252.9 (1.9 ) 251.0 Inventories 266.4 (12.3 ) 254.1 Other current assets 40.0 1.6 41.6 Property, plant and equipment 247.6 (1.6 ) 246.0 Goodwill 1,242.8 182.9 1,425.7 Identifiable intangible assets 1,150.0 (63.5 ) 1,086.5 Other noncurrent assets 22.3 3.0 25.3 Current liabilities (224.2 ) (4.8 ) (229.0 ) Noncurrent pension liabilities (30.5 ) 18.9 (11.6 ) Other noncurrent liabilities (27.1 ) (107.8 ) (134.9 ) Net acquisition cost $ 3,003.9 $ 14.5 $ 3,018.4 The Company has recorded measurement period adjustments since the acquisition date primarily related to the finalization of the valuation of inventory, intangible assets, plant and equipment, pension liabilities and deferred taxes. The impact of these measurement period adjustments to the Consolidated Statements of Operations and Comprehensive Income (Loss) were not material to 2016 or 2015 and if these adjustments had been applied at the original acquisition date, the impact to current year and prior year periods would also have been immaterial. The goodwill arising from the purchase price allocation of the BNS acquisition is believed to result from the business’ reputation in the marketplace and assembled workforce. A significant portion of the goodwill is expected to be deductible for income tax purposes. Various valuation techniques were used to estimate the fair value of the assets acquired and the liabilities assumed which use significant unobservable inputs, or Level 3 inputs as defined by the fair value hierarchy. Using these valuation approaches requires the Company to make significant estimates and assumptions. The table below summarizes the valuations of the intangible assets acquired that were determined by management to meet the criteria for recognition apart from goodwill. Estimated Fair Value (in millions) Weighted Average Estimated Useful Life (in years) Customer contracts and relationships $ 686.2 12 Trademarks 53.3 7 Patents and technologies 347.0 7 Total amortizable intangible assets $ 1,086.5 There were certain foreign assets acquired and liabilities assumed in the BNS acquisition for which title did not transfer at the acquisition date although the consideration was paid as part of the overall purchase price discussed above. As of December 31, 2016, these transfers have been completed. The BNS amounts included in the following pro forma information are based on their historical results prepared on a carve-out basis of accounting and, therefore, may not be indicative of the actual results when operated as part of CommScope. The pro forma adjustments represent management’s best estimates based on information available at the time the pro forma information was prepared and may differ from the adjustments that may actually have been required. Accordingly, the pro forma financial information should not be relied upon as being indicative of the results that would have been realized had the acquisition occurred as of the date indicated or that may be achieved in the future. The following table presents unaudited pro forma consolidated results of operations for CommScope for the years ended December 31, 2015 and 2014 as though the BNS acquisition had been completed as of January 1, 2014 (in millions, except per share amounts): Year Ended December 31, 2015 2014 Net sales $ 4,978.4 $ 5,721.4 Net income 46.7 157.3 Net income per diluted share 0.24 0.82 These pro forma results reflect adjustments for net interest expense for the debt related to the acquisition; depreciation expense for property, plant and equipment that has been adjusted to its estimated fair value; amortization for intangible assets with finite lives identified separate from goodwill; equity-based compensation for equity awards issued to BNS employees; and the related income tax impacts of these adjustments. The pro forma results for the year ended December 31, 2015, exclude $93.6 million of integration and transaction costs related to the BNS acquisition and $81.6 million of additional cost of goods sold related to the inventory mark up included in the purchase price allocation as these costs are nonrecurring to the Company. Airvana On October 1, 2015, the Company acquired the assets and assumed certain liabilities of Airvana LP (Airvana), a provider of small cell solutions for wireless networks. The Company paid $45.1 million ($44.5 million net of cash acquired). Airvana provides 4G LTE and 3G small cell solutions that enable communication and access to information and entertainment in challenging and high-value environments, such as office buildings and public venues. Net sales of Airvana products reflected in the Consolidated Statements of Operations and Comprehensive Income (Loss) were $17.1 million and $4.2 million for the years ended December 31, 2016 and 2015, respectively, and are reported in the CMS segment. The allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows (in millions): Estimated Fair Value Cash and cash equivalents $ 0.6 Accounts receivable 4.2 Other assets 3.8 Property, plant and equipment 2.5 Goodwill 20.4 Identifiable intangible assets 19.1 Less: Liabilities assumed (5.5 ) Net acquisition cost $ 45.1 The goodwill arising from the purchase price allocation of the Airvana acquisition is believed to result from the company’s reputation in the marketplace and assembled workforce and is expected to be deductible for income tax purposes.

Pretax charges of $15.0 million were recognized in asset impairments on the Consolidated Statements of Operations and Comprehensive Income (Loss). During 2015, the Company determined that certain patent and technology intangible assets in the CCS segment were no longer recoverable and recorded a pretax $5.5 million impairment charge in asset impairments on the Consolidated Statements of Operations and Comprehensive Income (Loss). The Company’s finite-lived intangible assets are being amortized on a straight-line basis over the weighted-average amortization periods in the following table. The aggregate weighted-average amortization period is 11.8 years. Weighted- Average Amortization Period (in years) Customer base 11.0 Trade names and trademarks 18.9 Patents and technologies 6.8 Amortization expense for intangible assets was $297.2 million, $220.6 million and $178.3 million for the years ended December 31, 2016, 2015 and 2014, respectively. Estimated amortization expense for the next five years is as follows (in millions): Estimated Amortization Expense 2017 $ 265.3 2018 254.1 2019 225.2 2020 219.1 2021 199.6 As a result of the change in segments, goodwill was reallocated from the previous segments to the new segments. The following table presents goodwill after the reallocation to the new reportable segments (in millions): CCS CMS Total Goodwill, gross, as of December 31, 2013 $ 745.8 $ 821.1 $ 1,566.9 Acquisitions and adjustments to purchase price allocations (5.7 ) 15.3 9.6 Foreign exchange — (3.3 ) (3.3 ) Goodwill, gross, as of December 31, 2014 740.1 833.1 1,573.2 Acquisitions and adjustments to purchase price allocations 1,265.1 69.7 1,334.8 Foreign exchange (18.6 ) (3.1 ) (21.7 ) Goodwill, gross, as of December 31, 2015 1,986.6 899.7 2,886.3 Adjustments to purchase price allocations 107.7 4.4 112.1 Foreign exchange (16.8 ) (2.3 ) (19.1 ) Goodwill, gross, as of December 31, 2016 $ 2,077.5 $ 901.8 $ 2,979.3 Accumulated impairment charges as of December 31, 2013 $ (36.2 ) $ (80.2 ) $ (116.4 ) Impairment charges for year ended December 31, 2014 — (4.9 ) (4.9 ) Accumulated impairment charges as of December 31, 2014 (36.2 ) (85.1 ) (121.3 ) Impairment charges for year ended December 31, 2015 — (74.4 ) (74.4 ) Accumulated impairment charges as of December 31, 2015 (36.2 ) (159.5 ) (195.7 ) Impairment charges for year ended December 31, 2016 (15.3 ) — (15.3 ) Accumulated impairment charges as of December 31, 2016 $ (51.5 ) $ (159.5 ) $ (211.0 ) Goodwill, net, as of December 31, 2016 $ 2,026.0 $ 742.3 $ 2,768.3 During 2016, management assessed goodwill for impairment due to the change in reportable segments, which also resulted in changes to several reporting units. As a result, the Company performed impairment testing for goodwill under the reporting unit structure immediately before the change and determined that no impairment existed. The Company reallocated goodwill to the new reporting units under the new reporting structure and performed impairment testing for goodwill under the new segment reporting structure immediately after the change and determined that a $15.3 million goodwill impairment existed within one of the CCS reporting units at January 1, 2016. The impairment test was performed using a discounted cash flow (DCF) valuation model. The significant assumptions in the DCF model are annual revenue growth rates, annual operating income margins and the discount rate used to determine the present value of the cash flow projections. The discount rate was based on the estimated weighted average cost of capital as of the test date for market participants in our reporting units’ industries. Goodwill impairment charges of $74.4 million and $4.9 million were recorded during 2015 and 2014, respectively, primarily due to lower future projected operating results for certain reporting units that are now part of the CMS segment.

Interest is payable on the 2025 Notes semi-annually in arrears on June 15 and December 15 of each year. The Company used the proceeds from the June 2015 offering of the 2025 Notes, together with cash on hand and borrowings under the senior secured term loan facility due December 2022, to finance the acquisition of the BNS business. Each of the Company’s existing and future direct and indirect domestic subsidiaries that guarantees the senior secured credit facilities guarantees the 2025 Notes on a senior unsecured basis. The 2025 Notes and the guarantees are unsecured senior obligations ranking equal in right of payment to all of the Company’s and the guarantors’ existing and future senior indebtedness, including its senior secured credit facilities. However, the 2025 Notes and guarantees are effectively junior to all of the Company’s and the guarantors’ existing and future secured debt, including the 2020 Notes and its senior secured credit facilities, to the extent of the value of the assets securing such secured debt. In addition, the 2025 Notes are structurally subordinated to all existing and future liabilities (including trade payables) of the Company’s subsidiaries that do not guarantee the 2025 Notes, including indebtedness incurred by certain of the Company’s non-U.S. subsidiaries under the revolving credit facility. 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 face amount, plus accrued and unpaid interest. Prior to June 15, 2020, the 2025 Notes may be redeemed at a redemption price equal to 100% of their principal amount, plus a make-whole premium (as defined in the indenture governing the 2025 Notes), plus accrued and unpaid interest. On or prior to June 15, 2018, under certain circumstances, the Company may also redeem up to 40% of the aggregate principal amount of the 2025 Notes at a redemption price of 106.0%, plus accrued and unpaid interest, using the proceeds of certain equity offerings. In connection with issuing the 2025 Notes, the Company incurred costs of $35.9 million during the year ended December 31, 2015, which were recorded as a reduction of the carrying amount of the debt and are being amortized over the term of the notes. 5.00% Senior Notes Due 2021 and 5.50% Senior Notes Due 2024 In May 2014, CommScope, Inc., a wholly owned subsidiary of the Company, issued $650.0 million of 5.00% Senior Notes due June 15, 2021 (the 2021 Notes) and $650.0 million of 5.50% Senior Notes due June 15, 2024 (the 2024 Notes). Interest is payable on the 2021 Notes and the 2024 Notes semi-annually in arrears on June 15 and December 15 of each year. Proceeds from the 2021 Notes and the 2024 Notes were used to redeem the entire outstanding amount of the 8.25% senior notes due January 2019 (the 2019 Notes) plus pay a redemption premium of $93.9 million, which was included in other expense, net for the year ended December 31, 2014. The remainder of the net proceeds was available for general corporate purposes. In connection with the redemption of the 2019 Notes, the Company wrote off $19.1 million of debt issuance costs to interest expense during the year ended December 31, 2014. The 2021 Notes and the 2024 Notes are guaranteed on a senior unsecured basis by CommScope, Inc. and its domestic restricted subsidiaries, subject to certain exceptions, as described above for the 2025 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 face amount, plus accrued and unpaid interest to the date of purchase. Prior to June 15, 2017 in the case of the 2021 Notes and June 15, 2019 in the case of the 2024 Notes, the 2021 Notes and the 2024 Notes may be redeemed at a redemption price equal to 100% of their principal amount, plus a make-whole premium (as defined in the indentures governing the 2021 Notes and the 2024 Notes), plus accrued and unpaid interest to the redemption date. On or prior to June 15, 2017, under certain circumstances, the Company may also redeem up to 40% of the aggregate principal amount of each series of the 2021 Notes and the 2024 Notes at a redemption price of 105.0% in the case of the 2021 Notes or 105.5% in the case of the 2024 Notes, plus accrued and unpaid interest to the redemption date using the proceeds of certain equity offerings. In connection with issuing the 2021 Notes and the 2024 Notes, the Company incurred costs of $23.3 million during the year ended December 31, 2014, which were treated as a reduction of long-term debt and are being amortized over the terms of the notes. Senior PIK Toggle Notes In May 2013, the Company issued $550.0 million of 6.625%/7.375% Senior Payment-in-Kind Toggle Notes due 2020 (the senior PIK toggle notes) in a private offering. In December 2015, the Company repurchased $13.4 million of the senior PIK toggle notes. The repurchase resulted in a $0.3 million charge which is reflected in other expense, net. In connection with the repurchase, $0.2 million of debt issuance costs were written off and included in interest expense. During 2016, the Company voluntarily redeemed the remaining $536.6 million of the senior PIK toggle notes. The redemptions resulted in a $17.7 million charge which is reflected in other expense, net. In connection with the redemptions, $6.1 million of debt issuance costs were written off and included in interest expense. 4.375% Senior Secured Notes Due 2020 In June 2015, CommScope, Inc., a wholly owned subsidiary of the Company, issued $500.0 million of 4.375% Senior Secured Notes due June 15, 2020 (the 2020 Notes). Interest is payable on the 2020 Notes semi-annually in arrears on June 15 and December 15 of each year. The Company used the net proceeds of the offering of the 2020 Notes, together with cash on hand, to repay the entire principal amount outstanding under the term loan due 2017 and a portion of the principal amount outstanding under the term loan due 2018. The 2020 Notes are guaranteed on a senior secured basis by CommScope Holding Company, Inc. and its domestic restricted subsidiaries, subject to certain exceptions, and are 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 2020 Notes may be redeemed prior to maturity under certain circumstances. Upon certain change of control events, the 2020 Notes may be redeemed at the option of the holders at 101% of their face amount, plus accrued and unpaid interest. Prior to June 15, 2017, the 2020 Notes may be redeemed at a redemption price equal to 100% of their principal amount, plus a make-whole premium (as defined in the indenture governing the 2020 Notes), plus accrued and unpaid interest. Prior to June 15, 2017, under certain circumstances, the Company may also redeem up to 40% of the aggregate principal amount of the 2020 Notes at a redemption price of 104.375%, plus accrued and unpaid interest, using the proceeds of certain equity offerings. In connection with issuing the 2020 Notes, the Company incurred costs of approximately $8.5 million during the year ended December 31, 2015, which were recorded as a reduction of the carrying amount of the debt and are being amortized over the term of the notes. 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 revolving credit facility expires in May 2020, subject to acceleration under certain circumstances. As of December 31, 2016, the Company had no outstanding borrowings under its revolving credit facility and the Company did not borrow under its revolving credit facility during the year ended December 31, 2016. As of December 31, 2016, the Company had availability of $441.1 million under its revolving credit facility, after giving effect to borrowing base limitations and outstanding letters of credit. In June 2015, the Company borrowed $1.25 billion, less $3.1 million of original issue discount, in a term loan due December 2022 (the 2022 Term Loan) under its existing senior secured credit facilities. The Company used the proceeds from the 2022 Term Loan, together with cash on hand and proceeds from the issuance of the 2025 Notes, to finance the acquisition of the BNS business. The Company incurred costs of $29.7 million during the year ended December 31, 2015 related to the additional borrowings under the term loan facility. These costs were recorded as a reduction of the carrying amount of the debt and are being amortized over the term of the 2022 Term Loan. The 2022 Term Loan has scheduled maturities of $12.5 million per year due in equal quarterly installments with the balance due at maturity. During the year ended December 31, 2016, the Company amended the 2022 Term Loan to reduce the margin on the interest rate. 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 1.50% 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 2.50%, subject to a LIBOR floor of 0.75%. Before the amendment, the margin on the interest rate in (1) above was 2.00% and in (2) above was 3.00%. The Company recorded an additional $3.1 million of original issue discount in 2016 related to this amendment. During the year ended December 31, 2016, the Company repaid $150.0 million of its Term Loan due January 2018. In connection with this voluntary repayment, $1.0 million of original issue discount and debt issuance costs were written off and included in interest expense. During the year ended December 31, 2015, the Company repaid $605.3 million of its senior secured term loans. In connection with early voluntary repayments of term loans, $7.9 million of original issue discount and debt issuance costs were written off and included in interest expense. The senior secured term loans are 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. The current portion of long-term debt reflects the $12.5 million of annual repayments under the 2022 Term Loan. No portion of the senior secured term loans was reflected as a current portion of long-term debt as of December 31, 2016 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 2016 related to 2015. Other Matters The following table summarizes scheduled maturities of long-term debt as of December 31, 2016 (in millions): 2017 2018 2019 2020 2021 Thereafter Scheduled maturities of long-term debt $ 12.5 $ 124.4 $ 12.5 $ 512.5 $ 662.5 $ 3,321.9 The Company’s non-guarantor subsidiaries held $2,211 million, or 31%, of total assets and $615 million, or 11%, of total liabilities as of December 31, 2016 and accounted for $2,101 million, or 43%, of net sales for the year ended December 31, 2016. As of December 31, 2015, the non-guarantor subsidiaries held $2,848 million, or 38%, of total assets and $468 million, or 8%, of total liabilities. For the year ended December 31, 2015, the non-guarantor subsidiaries accounted for $1,723 million, or 45%, 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 5.24% at December 31, 2016 and 5.50% at December 31, 2015.

Fair Value Measurements	8. FAIR VALUE MEASUREMENTS The Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, available-for-sale securities, debt instruments and foreign currency contracts. For cash and cash equivalents, trade receivables and trade payables, the carrying amounts of these financial instruments as of December 31, 2016 and December 31, 2015 were considered representative of their fair values due to their short terms to maturity. The fair value of the Company’s available-for-sale securities were based on quoted market prices. The fair values of the Company’s debt instruments and foreign currency contracts were based on indicative quotes. Fair value measurements using quoted prices in active markets for identical assets and liabilities fall within Level 1 of the fair value hierarchy, measurements using significant other observable inputs fall within Level 2, and measurements using significant unobservable inputs fall within Level 3. The carrying amounts, estimated fair values and valuation input levels of the Company’s available-for-sale securities, foreign currency contracts and debt instruments as of December 31, 2016 and December 31, 2015, are as follows: December 31, 2016 December 31, 2015 Carrying Amount Fair Value Carrying Amount Fair Value Valuation Inputs Assets: Available-for-sale securities $ 5,212 $ 5,212 $ 11,683 $ 11,683 Level 1 Foreign currency contracts 289 289 1,051 1,051 Level 2 Liabilities: 6.00% senior notes due 2025 1,500,000 1,585,350 1,500,000 1,430,700 Level 2 5.50% senior notes due 2024 650,000 673,530 650,000 617,500 Level 2 5.00% senior notes due 2021 650,000 669,500 650,000 619,125 Level 2 Senior PIK toggle notes due 2020 — — 536,630 544,679 Level 2 4.375% senior secured notes due 2020 500,000 513,100 500,000 500,000 Level 2 Senior secured term loan due 2022, at par 1,234,375 1,245,145 1,246,875 1,243,727 Level 2 Senior secured term loan due 2018, at par 111,875 112,364 261,875 260,068 Level 2 Foreign currency contracts 8,349 8,349 5,945 5,945 Level 2 Non-Recurring Fair Value Measurements During the year ended December 31, 2016, the Company recorded the following pretax impairment charges that resulted from fair value measurements based on Level 3 valuation inputs: • Goodwill impairment charge of $15.3 million related to one of the CCS reporting units in the first quarter of 2016 as a result of impairment testing requirements under the new segment reporting structure. • Impairment charges of $7.4 million and $7.6 million in the third and fourth quarters of 2016, respectively, to reduce certain intangible assets in the CCS segment to their estimated fair value. • Impairment charge of $8.3 million in the fourth quarter of 2016 to reduce certain long-lived assets no longer expected to be utilized in operations in the CCS segment to its estimated fair value. During the year ended December 31, 2015, the Company recorded the following pretax impairment charges that resulted from fair value measurements based on Level 3 valuation inputs: • Goodwill impairment charge of $74.4 million related to the CMS segment as a result of reduced expectations of future cash flows from one of its reporting units in the third quarter of 2015. • Impairment charge of $5.5 million related to certain intangible assets in the CCS segment that were no longer recoverable as of December 31, 2015. 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 Prior to the acquisition of the BNS business, the Company initiated restructuring actions to realign and lower its cost structure primarily through workforce reductions and other cost reduction initiatives, including the cessation of manufacturing operations at various facilities. Production capacity from these facilities has been shifted to other existing facilities or unaffiliated suppliers. These actions are referred to as cost alignment restructuring actions. Following the acquisition of BNS in 2015, the Company initiated a series of restructuring actions to integrate the BNS operations (BNS integration restructuring actions) to achieve cost synergies. All charges related to these restructuring actions are reported in restructuring costs, net. The Company’s net pretax restructuring charges, by segment, were as follows: Year Ended December 31, 2016 2015 2014 CCS $ 27,098 $ 16,937 $ 3,076 CMS 15,777 12,551 16,191 Total $ 42,875 $ 29,488 $ 19,267 Employee-related costs include the expected severance costs and related benefits as well as one-time severance benefits that are accrued over the remaining period employees are required to work in order to receive such benefits. Lease termination costs relate to the discounted cost of unused leased facilities, net of anticipated sub-lease income. Fixed asset related costs include non-cash impairments or disposals of fixed assets 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. These costs are expensed as incurred. Cash paid is net of proceeds received from the sale of related assets. As a result of restructuring and consolidation actions, the Company owns unutilized real estate at various facilities in the U.S. and internationally. The Company is attempting to sell or lease this unutilized space. Additional impairment charges may be incurred related to these or other excess assets. T he activity within the liability established for the cost alignment restructuring actions was as follows: Employee- Related Costs Lease Termination Costs Fixed Asset Related Costs Total Balance as of December 31, 2013 $ 17,173 $ 1,399 $ — $ 18,572 Additional charge recorded 6,625 8,048 4,594 19,267 Cash paid (19,806 ) (1,205 ) (3,357 ) (24,368 ) Foreign exchange and other non-cash items (170 ) 1 (1,237 ) (1,406 ) Balance as of December 31, 2014 3,822 8,243 — 12,065 Additional charge recorded 3,024 865 1,828 5,717 Cash paid (5,773 ) (1,738 ) (247 ) (7,758 ) Consideration received — — 2,986 2,986 Foreign exchange and other non-cash items (68 ) — (4,567 ) (4,635 ) Balance as of December 31, 2015 1,005 7,370 — 8,375 Additional charge recorded 71 298 (203 ) 166 Cash paid (769 ) (1,618 ) — (2,387 ) Consideration received — — 3,656 3,656 Foreign exchange and other non-cash items 4 — (3,453 ) (3,449 ) Balance as of December 31, 2016 $ 311 $ 6,050 $ — $ 6,361 The Company has recognized restructuring charges of $89.0 million since January 2011 for cost alignment restructuring actions.

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. With the BNS acquisition in 2015, the Company assumed various international defined contribution retirement savings plans and BNS employees in the U.S. became eligible to participate in the U.S. 401(k) plan. During the years ended December 31, 2016, 2015 and 2014, the Company made contributions to defined contribution retirement savings plans of $24.5 million, $21.7 million and $19.6 million, respectively. The Company maintains noncontributory and contributory deferred compensation plans. During the years ended December 31, 2016, 2015 and 2014, the Company recognized pretax costs of $2.6 million, $1.4 million and $2.0 million, respectively, related to these plans. The liability was $32.5 million and $27.4 million as of December 31, 2016 and 2015, respectively. Pension and Other Postretirement Benefit Plans The Company sponsors defined benefit pension plans covering certain domestic former employees and certain foreign current and former employees. With the acquisition of the BNS business, the Company assumed various foreign defined benefit pension plans. Included in the defined benefit pension plans are both funded and unfunded plans. The Company also sponsors postretirement health care and life insurance benefit plans that provide benefits to certain domestic former employees and certain domestic 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 accounting for 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.

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. Substantially all of the U.S. pension assets and 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 estimated fair values and the valuation input levels of the Company’s plan assets as of December 31, 2016 are as follows: Pension Benefits Other Postretirement Benefits U.S. Plans Non-U.S. Plans U.S. Plans Level 1 Fair Value Level 2 Fair Value Level 1 Fair Value Level 2 Fair Value Level 1 Fair Value Level 2 Fair Value Mutual funds: U.S. equity $ 2,693 $ — $ — $ — $ — $ — International equity 1,284 — 30,295 29,618 — — U.S. debt 142,121 — — — — — International debt 6,847 — 27,004 81,242 — — Absolute return — — — 18,727 — — Other 2,693 — 3,688 6,244 — — Total $ 155,638 $ — $ 60,987 $ 135,831 $ — $ — The estimated fair values and the valuation input levels of the Company’s plan assets as of December 31, 2015 are as follows: Pension Benefits Other Postretirement Benefits U.S. Plans Non-U.S. Plans U.S. Plans Level 1 Fair Value Level 2 Fair Value Level 1 Fair Value Level 2 Fair Value Level 1 Fair Value Level 2 Fair Value Mutual funds: U.S. equity $ 2,404 $ — $ — $ — $ — $ — International equity 1,692 — 28,309 50,240 — — U.S. debt 140,264 — — — 592 — International debt 6,164 — 26,721 91,772 — — Other 2,137 — 1,223 1,650 — — Total $ 152,661 $ — $ 56,253 $ 143,662 $ 592 $ — Expected Cash Flows The Company expects to contribute $0.3 million to U.S defined benefit pension plans and $6.6 million to non-U.S. defined benefit pension plans during 2017.

The deferred tax asset for federal tax credit carryforwards as of December 31, 2016 relates to U.S. foreign tax credit carryforwards that expire between 2017 and 2025. During the year ended December 31, 2016, the Company released $28.9 million of valuation allowance against these deferred tax assets based on changes in outlook regarding the level and mix of foreign and domestic earnings that improved the expected ability to realize these assets. The deferred tax asset for state net operating loss and tax credit carryforwards as of December 31, 2016 includes state net operating loss carryforwards (net of federal tax impact) of $15.8 million, which begin to expire in 2017, and state tax credit carryforwards (net of federal tax impact) of $1.4 million which begin to expire in 2017. A valuation allowance of $10.5 million has been established against these state income tax related deferred tax assets. The deferred tax assets for foreign net operating losses and tax credit carryforwards as of December 31, 2016 include foreign net operating loss carryforwards (tax effected) of $44.0 million, which will begin to expire in 2017, and foreign tax credit carryforwards of $12.1 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 $45.6 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 $4.0 million against other deferred tax assets. During the year ended December 31, 2016, the valuation allowance for deferred tax assets decreased by $41.4 million, primarily due to the changes in outlook for foreign tax credit carryforwards described above. Of that decrease, $34.0 million reduced tax expense and the balance was related to changes in the underlying deferred tax assets or was recorded as an adjustment to other comprehensive income. As of December 31, 2016, a deferred tax liability of $9.8 million has been established to reflect the U.S. federal and state tax cost associated with the planned repatriation of that portion of the Company’s undistributed foreign earnings that are not considered to be permanently reinvested in foreign operations. The remaining amount of undistributed earnings from foreign subsidiaries for which no incremental U.S. income taxes have been provided was $606.1 million as of December 31, 2016 as these earnings are considered to be permanently reinvested in foreign operations. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable. 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, 2016 2015 2014 Balance at beginning of period $ 64,085 $ 68,223 $ 91,410 Increase related to prior periods 742 1,677 223 Decrease related to prior periods (3,416 ) (2,094 ) (1,275 ) Increase related to current periods — 914 — Decrease related to settlement with taxing authorities (22 ) — — Decrease related to lapse in statutes of limitations (16,758 ) (4,635 ) (22,135 ) Increase related to acquisition 3,681 — — Balance at end of period $ 48,312 $ 64,085 $ 68,223 The Company’s liability for unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate in future periods was $39.5 million as of December 31, 2016. 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 reasonably estimates that the balance of unrecognized tax benefits, excluding the impact of accrued interest and penalties, may be reduced by up to $10.0 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, 2016 and 2015, the Company had accrued $8.9 million and $7.9 million, respectively, for interest and penalties. During the years ended December 31, 2016, 2015 and 2014 the net expense (credit) for interest and penalties recognized through income tax expense was $0.4 million, $(0.5) million and $(4.6) million, respectively. The Company files 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 2013 or state and local tax examinations for years prior to 2012. 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 2011. 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 2016, the Company recognized $16.8 million related to the lapse of applicable statutes of limitations and the conclusion of various domestic and foreign examinations.

Stockholders' Equity	12. STOCKHOLDERS’ EQUITY Equity-Based Compensation Plans On October 4, 2013, 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 the CommScope, Inc. 2011 Incentive Plan As of December 31, 2016, $54.3 million of total unrecognized compensation expense related to non-vested stock options, RSUs and PSUs are expected to be recognized over a remaining weighted average period of 1.4 years. There were no significant capitalized equity-based compensation costs at December 31, 2016. In March 2016, the Company modified certain stock option awards to extend the exercise period in the case of retirement, death or disability. This modification resulted in a change in the fair value of the affected awards. Incremental compensation cost of $1.6 million resulted from the modification and was fully recognized at the time of the modification. The following table shows a summary of the equity-based compensation expense included in the Consolidated Statements of Operations and Comprehensive Income (Loss): Year Ended December 31, 2016 2015 2014 Selling, general and administrative $ 26,709 $ 21,829 $ 15,592 Cost of sales 4,665 3,844 3,160 Research and development 3,632 2,992 2,340 Total equity-based compensation expense $ 35,006 $ 28,665 $ 21,092 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 one to 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 amounts): Shares Weighted Average Option Exercise Price Per Share Weighted Average Remaining Contractual Term in Years Aggregate Intrinsic Value Options outstanding as of December 31, 2015 7,458 $ 8.81 Granted 385 $ 25.08 Exercised (2,116 ) $ 7.91 Forfeited (230 ) $ 8.02 Options outstanding as of December 31, 2016 5,497 $ 10.33 4.7 $ 147,706 Options exercisable at December 31, 2016 4,725 $ 7.53 4.1 $ 140,173 Options expected to vest at December 31, 2016 771 $ 27.45 8.5 $ 7,514 The total intrinsic value of options exercised during the years ended December 31, 2016, 2015 and 2014 was $50.6 million, $77.0 million and $35.7 million, respectively. The exercise prices of outstanding options at December 31, 2016 were in the following ranges: Options Outstanding Options Exercisable Range of Exercise Prices Shares (in thousands) Weighted Average Remaining Contractual Life (in years) Weighted Average Exercise Price Per Share Shares (in thousands) Weighted Average Exercise Price Per Share $2.96 to $5.35 379 2.2 $ 2.96 379 $ 2.96 $5.36 to $5.67 211 4.9 $ 5.57 197 $ 5.57 $5.68 to $8.54 2,806 4.1 $ 5.74 2,806 $ 5.74 $8.55 to $8.90 963 3.5 $ 8.60 963 $ 8.60 $8.91 to $23.00 329 7.1 $ 22.73 329 $ 22.73 $23.01 to $33.12 809 8.5 $ 27.99 51 $ 29.73 $2.96 to $33.12 5,497 4.7 $ 10.33 4,725 $ 7.53 The Company uses the Black-Scholes model to estimate the fair value of stock option awards at the date of grant. Key inputs and assumptions used in the model include the grant date fair value of common stock, exercise price of the award, the expected option term, stock price volatility, the risk-free interest rate and the Company’s projected dividend yield. The risk-free interest rates reflect the yield on zero-coupon U.S. treasury securities with a term equal to the option’s expected term. The expected life represents the period over which the Company’s employees are expected to hold their options. Expected volatility is derived based on the historical Company volatility, as well as volatilities from publicly traded companies operating in the Company's industry. The Company’s projected dividend yield is zero. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in estimating the fair values of its stock options. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards. Subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company. The following table presents the weighted average assumptions used to estimate the fair value of stock option awards granted: Year Ended December 31, 2016 2015 2014 Expected option term (in years) 6.0 5.6 5.0 Risk-free interest rate 1.4 % 1.6 % 1.5 % Expected volatility 50.0 % 43.0 % 45.0 % Weighted average exercise price $ 25.08 $ 29.38 $ 23.02 Weighted average fair value at grant date $ 12.09 $ 13.74 $ 9.41 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 RSUs granted to BNS transferred employees in 2015 followed the remaining vesting schedule of their forfeited TE Connectivity awards which was a four-year vesting period. 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, 2015 1,567 $ 29.37 Granted 1,635 $ 24.93 Vested and shares issued (496 ) $ 30.90 Forfeited (187 ) $ 26.86 Non-vested share units at December 31, 2016 2,519 $ 26.37 The weighted average grant date fair value per unit of these awards granted during 2016, 2015 and 2014 was $24.93, $31.06 and $22.99, respectively. The total fair value of RSUs that vested during the years ended December 31, 2016 and 2015 was $15.3 million and $3.4 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 150% of the number of PSUs granted, depending on performance. The fair value of each PSU is determined on the date of grant based on the Company’s stock price. 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 will be based on the final performance metrics compared to the targets specified in the grants. For PSUs granted in 2015, which had a combined 2015 and 2016 earnings-based performance measure, the minimum level of performance was achieved but performance was below target resulting in a negative share performance adjustment. For PSUs granted in 2016, which had a 2016 earnings-based performance measure, a better than target performance level was achieved resulting in a positive share performance adjustment. These resulted in a net positive share performance adjustment in 2016. 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, 2015 175 $ 30.76 Granted 274 $ 25.05 Forfeited (11 ) $ 30.76 Performance adjustment 7 $ 27.65 Non-vested share units at December 31, 2016 445 $ 27.20 The weighted average grant date fair value per unit of these awards granted during 2016 and 2015 was $25.05 and $30.76, respectively.

Segment Reporting [Abstract]
Industry Segments, Major Customers, Related Party Transactions and Geographic Information	14. INDUSTRY SEGMENTS, MAJOR CUSTOMERS, RELATED PARTY TRANSACTIONS AND GEOGRAPHIC INFORMATION Segment Information As of January 1, 2016, the Company reorganized its internal management and reporting structure as part of integrating the BNS acquisition. The reorganization changed the information regularly reviewed by the Company’s chief operating decision maker to allocate resources and assess performance. The Company is reporting financial performance for the 2016 fiscal year based on these operating segments: CommScope Connectivity Solutions (CCS) and CommScope Mobility Solutions (CMS). Both CCS and CMS represent non-aggregated reportable operating segments. All prior period amounts below have been recast to reflect these operating segment changes. The CCS segment provides connectivity and network intelligence for indoor and outdoor network applications. Indoor network solutions are found in commercial buildings and in the network core, which includes data centers, central offices and cable television headends. These solutions include optical fiber and twisted pair structured cabling solutions, intelligent infrastructure software, network rack and cabinet enclosures, patch cords and panels, complete cabling systems and cable assemblies. central office connectivity and equipment and headend solutions for the network core. Outdoor network solutions are found in both local-area and wide-area networks and “last-mile” fiber-to-the-home installations. These solutions support the multichannel video, voice and high-speed data services provided by telecommunications operators and multi-system operators. The Company’s fiber optic connectivity solutions are primarily comprised of hardened connector systems, fiber distribution hubs and management systems, couplers and splitters, “plug and play” multiport service terminals, hardened optical terminating enclosures, high density cable assemblies, splices and splice closures. The CMS segment provides merchant radio frequency (RF) wireless network connectivity solutions as well as metro cell, DAS and small cell solutions to enable carriers’ 2G, 3G and 4G networks. These solutions enable wireless operators to increase spectral efficiency and enhance cellular coverage and capacity in challenging network conditions such as commercial buildings, urban areas, stadiums and transportation systems. The CMS segment focuses on all aspects of the radio access network (RAN) from the macro through the metro, to the indoor layer. Macro cell solutions can be found at wireless tower sites and on rooftops and include base station antennas, microwave antennas, hybrid fiber-feeder and power cables, coaxial cables, connectors and filters. Metro cell solutions can be found on street poles and on other urban, outdoor structures and include RF delivery and connectivity solutions, equipment housing and concealment. These fully integrated outdoor systems comprise specialized antennas, filters/combiners, backhaul solutions, intra-system cabling and power distribution, all minimized to fit an urban environment. The following table provides summary financial information by reportable segment (in millions): December 31, 2016 2015 Identifiable segment-related assets: CCS $ 4,507.5 $ 4,642.0 CMS 2,159.4 2,258.8 Total identifiable segment-related assets 6,666.9 6,900.8 Reconciliation to total assets: Cash and cash equivalents 428.2 562.9 Deferred income tax assets 46.9 38.9 Total assets $ 7,142.0 $ 7,502.6 The Company’s measure of segment performance is adjusted operating income. The Company defines adjusted operating income as operating income, adjusted to exclude amortization, asset impairments, equity-based compensation and other items that the Company believes are useful to exclude in the evaluation of operating performance from period to period because these items are not representative of the Company’s core business.

Summary of Significant Accoun22

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
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. The BNS acquisition was accounted for using the acquisition method of accounting. The results of the BNS business are reported in the Company’s consolidated financial statements from August 28, 2015 to December 25, 2015 for the year ended December 31, 2015 and from December 26, 2015 to December 30, 2016 for the year ended December 31, 2016. The BNS fiscal calendar included 53 weeks in 2016. Certain prior year amounts have been reclassified to conform to the current year presentation.
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	CommScope Holding Company, Inc. Notes to Consolidated Financial Statements (In thousands, unless otherwise noted) 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. 1
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, which are operating segments or one level below the operating segment level, 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. Goodwill impairment charges of $15.3 million, $74.4 million and $4.9 million were recorded during the years ended December 31, 2016, 2015 and 2014, respectively. See Notes 4 and 8 for further discussion of these impairment charges. Property, plant and equipment and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, based on the undiscounted cash flows expected to be derived from the use and ultimate disposition of the assets. Assets identified as impaired are carried at estimated fair value. During the years ended December 31, 2016, 2015 and 2014, the Company recognized pretax impairment charges for long-lived assets, other than goodwill impairments, of $23.3 million, $5.5 million and $7.2 million, respectively. See Notes 4 and 8 for further discussion of these impairment charges. During the year ended December 31, 2015, the Company determined that a note receivable related to a previous divestiture was likely impaired and recorded a $10.9 million impairment charge. Due to uncertain market conditions, it is possible that future impairment reviews may indicate additional impairments of goodwill and/or other intangible assets, 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. The cumulative amount of undistributed earnings from foreign subsidiaries for which no U.S. taxes have been provided was $606.1 million as of December 31, 2016. 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 Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the selling price is fixed or determinable and collectability is reasonably assured. The majority of the Company’s revenue comes from product sales. Revenue from product sales is recognized when the risks and rewards of ownership have passed to the customer and revenue is measurable. Revenue is not recognized related to product sold to contract manufacturers that the Company anticipates repurchasing in order to complete the sale to the ultimate customer. Revenue for certain of the Company’s products is derived from multiple-element contracts. The value of the revenue elements within these contracts is allocated based on the relative selling price of each element. The relative selling price is determined using vendor-specific objective evidence of selling price or other third party evidence of selling price, if available. If these forms of evidence are unavailable, revenue is allocated among elements based on management’s best estimate of the stand-alone selling price of each element. Revenue is generally recognized upon acceptance by the customer. For sales to distributors, system integrators and value-added resellers (primarily for the CCS segment), revenue is recorded at the net amount to be received after deductions for estimated discounts, allowances, 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 are recorded when circumstances indicate revisions may be necessary. If management does not have sufficient historical experience to make a reasonable estimation of these reductions to revenue, recognition of the revenue is deferred until management believes there is a sufficient basis to recognize such revenue.
Product Warranties	Product Warranties The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material.
Shipping and Handling Costs	Shipping and Handling Costs CommScope 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. Certain internal handling costs, which relate to activities to prepare goods for shipment, are recorded in selling, general and administrative expense and were approximately $56.2 million, $29.3 million and $27.2 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Advertising Costs	Advertising Costs Advertising costs are expensed in the period in which they are incurred. Advertising expense was $20.0 million, $13.6 million and $10.5 million for the years ended December 31, 2016, 2015 and 2014, 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, such as forward contracts, options, cross currency swaps, certain interest rate swaps, caps and floors and non-derivative financial instruments, such as foreign-currency-denominated loans, as hedges of these risks, 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. The Company did not designate any transactions as hedges in the years ended December 31, 2016, 2015 or 2014. Derivative contracts are measured at fair value and are marked to market each period through earnings. As such, there were no unrecognized gains or losses as of December 31, 2016 or 2015. 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, 2016, 2015 and 2014, approximately 46%, 51% and 45%, respectively, of the Company’s net sales were to customers located outside the United States (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 to 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 $9.5 million, $15.1 million and $2.7 million during the years ended December 31, 2016, 2015 and 2014, 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 are recorded to 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 that are ultimately expected to vest is recognized as expense over the requisite service periods. 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 additional paid-in capital (if the tax deduction exceeds the deferred tax asset) or in the Consolidated Statements of Operations and Comprehensive Income (Loss) as additional income tax expense (if the deferred tax asset exceeds the tax deduction and no excess additional paid-in capital exists from previous awards).
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is based on net income (loss) 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 (loss) per share because the effect was either antidilutive or the performance condition was not met (1.0 million, 5.9 million and 1.4 million shares for the years ended December 31, 2016, 2015 and 2014, respectively). Antidilutive securities for the year ended December 31, 2015 included 4.3 million shares of equity-based awards which would have been considered dilutive if the Company had not been in a net loss position. The following table presents the basis for the earnings (loss) per share computations: Year Ended December 31, 2016 2015 2014 Numerator: Net income (loss) for basic and diluted earnings (loss) per share $ 222,838 $ (70,875 ) $ 236,772 Denominator: Weighted average common shares outstanding - basic 192,470 189,876 186,905 Dilutive effect of equity-based awards 3,989 — 4,545 Weighted average common shares outstanding - diluted 196,459 189,876 191,450 Earnings (loss) per share: Basic $ 1.16 $ (0.37 ) $ 1.27 Diluted $ 1.13 $ (0.37 ) $ 1.24
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 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 and 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.
Business Combinations	Business Combinations The Company uses the acquisition method of accounting for business combinations which requires assets acquired and liabilities assumed to be recognized at their fair values on the acquisition date. Goodwill represents the excess of the purchase price 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 maximum potential 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, 2016, the Company did not have significant unreserved risk of credit loss due to the nonperformance 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 (copper, aluminum, steel, plastics and other polymers, bimetals and optical fiber) 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 2016 During the fourth quarter of 2016, the Company prospectively adopted Accounting Standards Update (ASU) No. 2015-11, Simplifying the Measurement of Inventory Issued but Not Adopted In August 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-15, Cash Flow Classification of Certain Cash Receipts and Cash Payments In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting In February 2016, the FASB issued ASU No. 2016-02, Leases Leases. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers During 2016, the Company completed an impact assessment and determined that adoption of the standard will likely result in changes to revenue recognition related to the timing of when revenues are recognized for contracts containing both product and service obligations. These contract revenues are currently accounted for using the multi-element guidance and are primarily for metro cell, DAS and small cell solutions within the CMS segment. Due to the short-term nature of these contracts, the ultimate impact to the Company’s consolidated financial statements will be based on customer-specific contract terms in effect at adoption, and could be material. The Company believes that changes to its accounting policies, processes, internal controls and information systems will be required to comply with this update. The Company is in the process of implementing the changes necessary to meet the standard update’s reporting and disclosure requirements.
