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 (CommScope or the Company). All intercompany accounts and transactions are eliminated in consolidation.

As a result of the application of acquisition accounting in 2011, the assets and liabilities of CommScope, Inc. were adjusted to their estimated fair values as of the closing date of the acquisition. Accordingly, the accompanying consolidated financial statements are presented separately for Predecessor and Successor accounting periods, which relate to the accounting periods preceding and succeeding the completion of the acquisition. The Predecessor and Successor periods have been separated by a vertical line on the face of the consolidated financial statements to highlight the fact that the financial information for such periods has been prepared under two different historical cost bases of accounting.

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.

Allowance for Doubtful Accounts

The Company maintains allowances for doubtful accounts for estimated losses expected to result from the inability of its customers to make required payments. These estimates are based on management’s evaluation of the ability of customers to make payments, focusing on historical experience, known customer financial difficulties and age of receivable balances.

Inventories

Inventories are stated at the lower of cost or market. Inventory cost is determined on a first-in, first-out (FIFO) basis. Costs such as idle facility expense, excessive scrap and rehandling costs are recognized as expenses as incurred. The Company maintains reserves to reduce the value of inventory to the lower of cost or market, including reserves for excess and obsolete inventory.

Long-Lived Assets

Property, Plant and Equipment

Property, plant and equipment are stated at cost, including interest costs associated with qualifying capital additions. Upon application of acquisition accounting, property, plant and equipment were 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 charged to expense 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 $36.2 million and $80.2 million were recorded in 2013 and 2011, 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 2013, 2012 and 2011, the Company recognized pretax impairment charges other than goodwill impairments of $9.3 million, $40.9 million and $45.9 million, respectively. See Notes 4 and 8 for further discussion of these impairment charges.

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 $398 million as of December 31, 2013. 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 income (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.

Certain revenue arrangements are for the sale of software and services. Revenue for software products is recognized based on the timing of customer acceptance of the specific revenue elements. The fair value of each revenue element is determined based on vendor-specific objective evidence of fair value determined by stand-alone pricing of each element. These contracts typically contain post-contract support (PCS) services which are sold both as part of a bundled product offering and as a separate contract. Revenue for PCS services is recognized ratably over the term of the PCS contract. Other service revenue is typically recognized once the service is performed or over the period of time covered by the arrangement.

For sales to distributors, system integrators and value-added resellers (primarily for the Enterprise segment), revenue is recorded at the net amount to be received after deductions for estimated discounts, allowances, returns and rebates. 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.

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 $27.3 million, $25.2 million, $20.5 million and $0.8 million for the year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2011 (Predecessor).

Advertising Costs

Advertising costs are expensed in the period in which they are incurred. Advertising expense was $10.3 million, $7.7 million, $9.5 million and $0.4 million for the year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2011 (Predecessor).

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 and non-derivative financial instruments 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 purposes, nor does it allow for speculation. A hedging instrument may be designated as a net investment hedge to manage exposure to foreign currency risks related to an investment in a foreign subsidiary; a fair value hedge to manage exposure to risks related to a foreign-currency-denominated cash or other account or a firm commitment for the purchase of raw materials or equipment; or a cash flow hedge to manage exposure to risks related to a forecasted purchase of raw materials, variable interest rate payments or a forecasted foreign-currency-denominated sale of product. The use of non-derivative financial instruments in hedging activities is limited to hedging fair value risk related to a foreign-currency-denominated firm commitment or a foreign currency risk related to a net investment in a foreign subsidiary.

The Company’s risk management strategy permits the reasonable and practical use of derivative hedging instruments such as forward contracts, options, cross currency swaps, certain interest rate swaps, caps and floors, and non-derivative hedging instruments such as foreign-currency-denominated loans. The Company recognizes all derivative financial instruments as assets or liabilities and measures them at fair value. All hedging instruments are designated and documented as a fair value hedge, a cash flow hedge or a net investment hedge at inception. For fair value hedges, the change in fair value of the derivative instrument is recognized currently in earnings. To the extent the fair value hedging relationship is effective, the change in fair value of the hedged item is recorded as an adjustment to the carrying amount of the hedged item and recognized currently in earnings. For cash flow hedges, the effective portion of the change in fair value of the derivative instrument is recorded in accumulated other comprehensive income (loss), net of tax, and is recognized in the consolidated statements of operations and comprehensive income (loss) when the hedged item affects earnings. Any ineffectiveness of a cash flow hedge is recognized currently in earnings. For net investment hedges, the effective portion of the change in fair value of a derivative instrument, or the change in carrying amount of a non-derivative instrument, is recorded in accumulated other comprehensive income (loss), net of tax, and is recognized in the consolidated statements of operations and comprehensive income (loss) only if there is a substantially complete liquidation of the investment in the foreign subsidiary. Any ineffectiveness of a net investment hedge is recognized currently in earnings. The effectiveness of designated hedging relationships is tested and documented on at least a quarterly basis.

In the Predecessor period of January 2011, the Company settled an interest rate swap liability that had been designated as a cash flow hedge to mitigate the cash flow effects of interest rate fluctuations on interest expense for a portion of its variable-rate debt instruments.

The Company also uses derivative instruments such as forward exchange contracts to manage the risk of foreign currency fluctuations. These instruments are not leveraged and are not held for trading or speculation. These contracts are not designated as hedges for accounting purposes and are marked to market each period through earnings and, as such, there were no unrecognized gains or losses as of December 31, 2013 or 2012. 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 year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2011 (Predecessor), approximately 45%, 47%, 49% and 49%, respectively, of the Company’s net sales were to customers located outside the U.S. A portion of these sales were denominated in currencies other than the U.S. dollar, particularly sales from the Company’s foreign subsidiaries. The financial position and results of operations of certain of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Revenues and expenses of these subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities of these subsidiaries have been translated at the exchange rates as of the balance sheet date. Translation gains and losses are recorded to accumulated other comprehensive income (loss).

Aggregate foreign currency transaction gains and losses of the Company and its subsidiaries, such as those resulting from the settlement of receivables or payables 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 $9.8 million, $7.0 million, $8.9 million and $1.1 million during the year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2001 (Predecessor), respectively. Foreign currency remeasurement gains and losses related to long-term intercompany loans that are not expected to be settled in the foreseeable future are recorded to accumulated other comprehensive income (loss).

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).

Tax benefits of $5.3 million resulting from the exercise of stock options that were vested as of the adoption of ASC Topic 718 Compensation—Stock Compensation were classified as financing cash inflows for the period January 1 – January 14, 2011 (Predecessor).

Common Stock, Preferred Stock and Stock Split

On October 4, 2013, the Company’s Board of Directors approved a 3-for-1 stock split of the Company’s outstanding common stock, which was effective as of October 4, 2013. Each share of issued and outstanding common stock was increased to 3 shares of common stock, the number of shares of common stock into which each outstanding option to purchase stock is exercisable was proportionally increased on a 3-for-1 basis, and the exercise price of each outstanding option to purchase common stock was proportionally decreased. All of the Successor period share numbers, share prices, exercise prices and other per share information throughout these financial statements have been adjusted on a retroactive basis, to reflect this 3-for-1 stock split, including reclassifying an amount equal to the increase in par value from additional paid-in capital. In conjunction with the Company’s IPO in October 2013, the Company’s Board of Directors authorized 1.3 billion shares of common stock, par value $0.01 per share and 0.2 billion shares of preferred stock, par value $0.01 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.

For the Predecessor period, diluted earnings (loss) per share is based on net income (loss) adjusted for after-tax interest and amortization of debt issuance costs related to convertible debt, if dilutive, divided by the weighted average number of common shares outstanding adjusted for the dilutive effect of stock options, restricted stock units, performance share units and convertible securities.

For the Successor periods diluted earnings (loss) per share is based on net income (loss) divided by the weighted average number of common shares outstanding adjusted for the dilutive effect of stock options.

Below is a reconciliation of earnings and weighted average common shares and potential common shares outstanding for calculating diluted earnings (loss) per share.

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.

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, 2013, 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, brass, 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.

Accounting Standards Not Yet Adopted

There are no recent accounting pronouncements that are currently anticipated to have a material impact on the Company.

	The Acquisition of CommScope, Inc. by Carlyle
	As discussed in Note 1, on January 14, 2011, funds affiliated with Carlyle completed the acquisition of CommScope, Inc. Net income (loss) during the periods January 15 – December 31, 2011 (Successor) and January 1 – January 14, 2011 (Predecessor) included certain charges that relate directly or indirectly to the acquisition by Carlyle, as listed below on a pretax basis:

	iTRACS Corporation
	In March 2013, the Company acquired substantially all of the assets and assumed certain liabilities of iTRACS Corporation (iTRACS) for approximately $34.0 million in cash. iTRACS develops and markets enterprise-class data center infrastructure management (DCIM) solutions. Net sales of iTRACS products and services were $0.8 million in 2013 and were reported in the Enterprise segment. The preliminary allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows:
			Estimated Fair Value
			(in millions)
	Current assets		$	1.6
	Noncurrent assets, excluding intangible assets			0.7
	Other intangible assets			13.1
	Goodwill			19.8
	Less: Liabilities assumed			(1.2	)
	Net acquisition cost		$	34
	The goodwill arising from the preliminary purchase price allocation of the iTRACS acquisition is believed to result from the company’s reputation in the marketplace and assembled workforce and is expected to be deductible for tax purposes.
	As additional information is obtained, adjustments may be made to the preliminary purchase price allocation. The Company is still finalizing the valuation of the fair value of certain tangible and intangible assets acquired.

	In July 2013, the Company acquired Redwood Systems, Inc. (Redwood), a provider of LED lighting solutions and integrated sensor networks for data centers and buildings. Redwood was acquired for an initial payment of $9.8 million and contingent consideration with an estimated fair value at the date of acquisition of $12.4 million. The Company may be required to pay up to an additional $37.25 million of consideration if certain net sales targets of up to $55.0 million are met over various periods through July 31, 2015. In addition, there are retention payments for employees of Redwood of up to $11.75 million based on the same net sales targets as the contingent consideration. Net sales of Redwood products and services were $1.7 million in 2013 and are reported in the Enterprise segment. The preliminary allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows:
			Estimated Fair Value
			(in millions)
	Current assets		$	2.8
	Deferred taxes			8.1
	Other intangible assets			9
	Goodwill			3.2
	Other noncurrent assets			0.8
	Less: Liabilities assumed			(1.7	)
	Net acquisition cost		$	22.2
	The goodwill arising from the preliminary purchase price allocation of the Redwood acquisition is believed to result from the company’s reputation in the marketplace and assembled workforce and is not expected to be deductible for tax purposes.
	The Company is still finalizing the valuation of certain tax attributes and as additional information is obtained, adjustments may be made to the preliminary purchase price allocation.
	Argus Technologies
	In 2013, the Company made the final payment of $12.0 million for the 2011 acquisition of Argus Technologies.
	BiMetals Sale
	In December 2013, the Company sold certain assets of its BiMetals business. The Company received $23.0 million in cash and a note with a face value of $15.0 million and a term of up to 7 years. The estimated fair value of the note was $9.8 million. A portion of the Company’s identified intangible assets ($2.9 million) and goodwill ($6.5 million) were allocated to the sale transaction. The Company recorded a net gain on the transaction of $18.7 million that was reported in restructuring costs, net on the Consolidated Statement of Operations and Comprehensive Income (Loss). The gain on sale is reported in the Broadband segment. In connection with the sale, the Company entered into a supply agreement with the purchaser for bimetallic wire as needed for the manufacture of cables and other products. No portion of the gain was allocated to the supply agreement.

	During 2012, as a result of reduced expectations of future cash flows of a reporting unit within the Wireless segment, certain intangible assets were determined to be impaired. A pretax impairment charge of $15.0 million for customer base, $8.3 million for trade names and trademarks and $6.0 million for patents and technologies intangible assets was recognized. The fair value of the intangible assets was estimated using a discounted cash flow method.
	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 12.6 years.

	During 2013, the Broadband segment experienced lower than expected levels of sales and operating income. Management considered these results and the longer term effect of market conditions on the continued operations of the business and determined that an indicator of possible impairment existed. A step one goodwill impairment test was performed using a discounted cash flow (DCF) valuation model. The significant assumptions in the DCF model are the annual revenue growth rate, the annual operating income margin, 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 of market participants in the industry in which the Broadband segment operates. Based on the estimated fair values generated by the DCF model, the Broadband segment did not pass step one of the goodwill impairment test. Accordingly, a step two analysis was completed and a $36.2 million impairment charge was recorded (included in asset impairments on the Consolidated Statement of Operations and Comprehensive Income (Loss) for the year ended December 31, 2013). The weighted average discount rate used in the impairment test for the Broadband segment was 11.0% compared to 11.5% that was used in the 2012 annual goodwill impairment test. The goodwill impairment charge resulted primarily from lower projected operating results than those assumed during the 2012 annual impairment test.
	No goodwill impairment charges were recorded in 2012. In connection with the annual goodwill impairment testing performed in 2011, the Company recorded goodwill impairment charges of $80.2 million, primarily as a result of lower projected operating results that were lower than those used in the purchase price allocation performed earlier in 2011.

	8.25% Senior Notes Due 2019
	The 2019 notes mature on January 15, 2019 and interest is payable semi-annually in arrears on January 15 and July 15 of each year. During 2013, the Company used the net proceeds from its initial public offering to redeem $400.0 million of its 2019 notes. In connection with the redemption, the Company paid a redemption premium of $33.0 million, which was included in other expense, net, and wrote off $7.9 million of deferred financing costs to interest expense.
	In addition to redemption using net proceeds from the issuance of securities, the 2019 notes may be redeemed prior to maturity under certain other circumstances. Upon the occurrence of certain events constituting a change of control, each holder of the 2019 notes may require the Company to purchase all or part of such notes for cash at a price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase. Each of the Company’s existing and future wholly owned domestic restricted subsidiaries guarantees the 2019 notes on a senior unsecured basis, to the extent such subsidiaries guarantee the U.S. tranches of the senior secured credit facilities. The 2019 notes and the guarantees are unsecured senior obligations ranking equal in right of payment to all of the Company’s existing and future senior indebtedness, including its senior secured credit facilities, and senior in right of payment to all of its existing and future indebtedness that is expressly subordinated in right of payment thereto. The 2019 notes and guarantees are effectively subordinated to all of the Company’s and the guarantors’ existing and future secured debt, including its senior secured credit facilities, to the extent of the value of the assets securing such secured debt. In addition, the 2019 notes are structurally subordinated to all existing and future liabilities (including trade payables) of the Company’s subsidiaries that do not guarantee the 2019 notes, including indebtedness incurred by certain of the Company’s non-U.S. subsidiaries under the revolving credit facility. In connection with issuing the 2019 notes, the Company incurred costs of approximately $45.7 million during the period January 15 – December 31, 2011 (Successor), which were capitalized as other noncurrent assets and are being amortized over the term of the notes. As of December 31, 2013, $24.7 million of such costs remain unamortized.
	Senior Secured Credit Facilities
	In connection with the acquisition of CommScope, Inc., the Company entered into senior secured credit facilities consisting of a $1.0 billion term loan and a $400 million asset-based revolving credit facility. The senior secured credit facilities are secured by substantially all of the Company’s assets and are guaranteed by substantially all of the Company’s active domestic subsidiaries.
	During both 2013 and 2012, the Company amended its senior secured term loan primarily to lower the interest rate. In connection with the December 2013 amendment, the Company made a voluntary repayment of $100.0 million of its senior secured term loan and increased the maximum amount of loans that can be incurred by adjusting the Consolidated Senior Secured Debt Ratio, as defined, from 2.25:1.00 to 2.75:1.00. In addition, the December 2013 amendment refinanced the senior secured term loan into two tranches, one of which was in the amount of $350.0 million and is due January 2017 (the 2017 term loan) and the other was in the amount of $525.0 million and is due January 2018 (the 2018 term loan). The interest rate margin applicable to the refinanced loans is, at the Company’s option, either (1) the base rate (which is the highest of the then current Federal Funds rate plus 0.5%, the prime rate most recently announced by JPMorgan Chase Bank, N.A., the administrative agent under the Credit Agreement, and the one-month Eurodollar rate (taking into account the Eurodollar rate floor, if any, plus 1.0%)) plus a margin of 1.50% or (2) one-, two-, three- or six-month LIBOR or, if available from all lenders, nine- or twelve-month LIBOR (selected at the Company’s option) plus a margin of 2.50%. The amendment also eliminated the 1.0% LIBOR floor with respect to the 2017 term loan and reduces it to 0.75% with respect to the 2018 term loan.
	During 2012, the Company also amended its asset-based revolving credit facility primarily to lower the interest rate and extend the term on the revolving credit facility. Among other changes to the revolving credit agreement, the expiration date was extended from January 14, 2016 to January 14, 2017 and the interest rate was amended such that outstanding principal under the revolving credit facility bears interest at a rate equal to, at the Company’s option, either (1) the base rate (as defined above) plus a margin that ranges from 0.50% to 1.00% or (2) one-, two-, three- or six-month LIBOR (or any other LIBOR period agreed to by the revolving lenders) plus a margin that ranges from 1.50% to 2.00%. The range of margins applied to base rate and LIBOR-based loans is subject to a pricing grid that is dependent on an excess availability calculation. As of December 31, 2013, the applicable margin was 0.50% for base rate loans and 1.50% for LIBOR loans. The unused line fee calculated on the undrawn portion of the revolving credit facility was amended so that the annual rate now ranges from 0.250% to 0.375% (0.375% as of December 31, 2013) based on usage of the facility.
	The amendments in 2013 and 2012 resulted in the repayment of $172.3 million and $104.6 million, respectively, to certain lenders who exited the senior secured term loan and revolving credit facility syndicates and the receipt of $172.3 million and $104.6 million, respectively, in proceeds from new lenders and existing lenders who increased their positions.
	As a result of the $100.0 million voluntary repayment and the 2013 amendments, $1.4 million of original issue discount and $2.0 million of deferred financing costs associated with the senior secured term loan were written off and included in interest expense for 2013. The Company also incurred pretax costs of $3.3 million, which were included in other expense, net for the year ended December 31, 2013 (Successor) on the Consolidated Statements of Operations and Comprehensive Income (Loss) and in long-term debt financing costs for the year ended December 31, 2013 (Successor) on the Consolidated Statements of Cash Flows.
	As a result of the 2012 amendments, $0.5 million of original issue discount and $2.6 million of deferred financing fees associated with the original senior secured term loan and revolving credit facility were written off and included in interest expense for 2012. Upfront fees of $10.4 million that were paid to lenders under the amended senior secured term loan and revolving credit facility were recorded as original issue discount and are being amortized over the terms of the facilities. In connection with the 2012 amendments, the Company also incurred pretax costs of $2.7 million, which were included in long-term debt financing costs for the year ended December 31, 2012 (Successor) on the Consolidated Statements of Cash Flows. Of the total costs incurred, $1.0 million was deferred and is being amortized over the terms of the facilities while the remaining $1.7 million was included in other expense, net for the year ended December 31, 2012 (Successor) on the Consolidated Statements of Operations and Comprehensive Income (Loss).
	During 2013, the Company borrowed and repaid $225.0 million under the revolving credit facility and made scheduled repayments of $9.7 million of its senior secured term loans. As of December 31, 2013, the Company had remaining availability of approximately $308.7 million under the asset-based revolving credit facility, reflecting a borrowing base of $362.8 million reduced by $54.1 million of letters of credit issued under the revolving credit facility.
	Senior PIK Toggle Notes
	On May 28, 2013, CommScope Holding Company, Inc. (the Parent 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, for proceeds of $538.8 million, net of debt issuance costs. The net proceeds from the issuance of the senior PIK toggle notes and available cash were used to fund $550.0 million of special cash dividends and distributions to the Parent Company’s equity holders. The senior PIK toggle notes are senior unsecured obligations that are not guaranteed by any of the Parent Company’s subsidiaries.
	The Parent Company may redeem the notes in whole or part during periods after June 1, 2016 at redemption prices (expressed as a percentage of the principal amount), plus accrued and unpaid interest to the redemption date, as follows: (i) June 1, 2016 through May 31, 2017 at 103.313%; (ii) June 1, 2017 through May 31, 2018 at 101.656%; and (iii) June 1, 2018 to maturity at 100.000%.
	Interest is due on the senior PIK toggle notes semi-annually in arrears on each June 1 and December 1. The first interest payment on the senior PIK toggle notes was paid in cash in December 2013. For each interest period, the Parent Company is required to pay interest on the senior PIK toggle notes entirely in cash, unless the Applicable Amount, as defined in the indenture governing the senior PIK toggle notes (the PIK Notes Indenture), is less than the applicable semi-annual requisite interest payment amount, in which case, the Parent Company may elect to pay a portion of the interest due on the senior PIK toggle notes for such interest period by increasing the principal amount of the senior PIK toggle notes or by issuing new notes for up to the entire amount of the interest payment (in each case, PIK interest) to the extent described in the PIK Notes Indenture. Cash interest on the senior PIK toggle notes will accrue at the rate of 6.625% per annum. PIK interest on the senior PIK toggle notes will accrue at the rate of 7.375% per annum until the next payment of cash interest.
	For the purposes of the PIK Notes Indenture, “Applicable Amount” generally refers to the Company’s then current restricted payment capacity under the instruments governing the Company’s other indebtedness, less $20 million, and plus the Parent Company’s cash and cash equivalents less $10 million. Based on the Applicable Amount, as of December 31, 2013, the Parent Company would be required to make its next interest payment on the senior PIK toggle notes entirely in cash.
	The senior PIK toggle notes are structurally subordinated to indebtedness and other liabilities of the Parent Company’s subsidiaries. Claims of creditors of such subsidiaries, including trade creditors, will have priority with respect to the assets and earnings of such subsidiaries over the holders of the senior PIK toggle notes. The Parent Company is a holding company with no material operations of its own and is, therefore, dependent upon the revenues and cash flows of its subsidiaries to service its debt obligations.

	7	DERIVATIVES AND HEDGING ACTIVITIES
	The Company uses forward contracts to hedge a portion of its foreign currency exchange rate exposure to balances denominated in currencies other than the functional currency of various subsidiaries. At December 31, 2013, the Company had foreign exchange contracts with maturities ranging from one to seven months with an aggregate notional value of $254 million (based on exchange rates as of December 31, 2013). Unrealized gains and losses resulting from these contracts are recognized in other expense, net and partially offset corresponding foreign exchange gains and losses on these balances. These instruments are not held for speculative or trading purposes. These contracts are not designated as hedges for hedge accounting and are marked to market each period through earnings.
	The following table presents the balance sheet location and fair value of the Company’s derivatives:
				Fair Value of Asset (Liability)
				Successor			Successor
			Balance Sheet Location	December 31, 2013			December 31, 2012

	Foreign currency contracts		Other accrued liabilities		(662	)		(474	)
	Total derivatives not designated as hedging instruments			$	2,076		$	840
	The fair value of the Company’s forward exchange contracts were based on indicative quotes, a Level 2 valuation input.
	The pretax impact of the foreign currency forward contracts not designated as hedging instruments on the Consolidated Statements of Operations and Comprehensive Income (Loss) is as follows:
	Foreign Currency Forward Contracts		Location of Gain (Loss)	Gain (Loss) Recognized

	8	FAIR VALUE MEASUREMENTS
	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 Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables and debt instruments. For cash and cash equivalents, trade receivables and trade payables, the carrying amounts of these financial instruments as of December 31, 2013 and 2012 were considered representative of their fair values due to their short terms to maturity. The fair value of the Company’s equity method investment is based on quoted market prices. The fair values of the Company’s debt instruments and foreign exchange contracts were based on indicative quotes. The fair value of contingent consideration is based on a probability weighted discounted cash flow analysis.
	The carrying amounts, estimated fair values and valuation input levels of the Company’s equity method investment, foreign currency contracts, 8.25% senior notes, senior secured term loans, senior PIK toggle notes and contingent consideration payable as of December 31, 2013 and 2012 are as follows:

	Foreign currency contracts			662		662		474		474	Level 2
	Contingent consideration payable			13,068		13,068		—		—	Level 3
	Contingent consideration payable represents the estimated fair value of the potential payment due related to the acquisition of Redwood. The contingent consideration is payable in 2015 and could range from zero to $37.25 million. The amount to be paid is based on the achievement of sales targets of Redwood products with a maximum payout reached with $55.0 million of sales by July 31, 2015. The estimated fair value of the contingent consideration was $12.4 million as of July 3, 2013, the Redwood acquisition date. Expense of $0.7 million related to the change in the estimated fair value of the contingent consideration was recorded in selling, general and administrative expense in the Consolidated Statement of Operations and Comprehensive Income (Loss) for the year ended December 31, 2013.
	Non-Recurring Fair Value Measurements
	During 2013, the Company recorded asset impairment charges of $45.5 million. The valuations supporting the following pretax impairment charges are based on Level 3 valuation inputs.
		•		Goodwill impairment charge of $36.2 million related to the Broadband segment as a result of reduced expectations of future cash flows, primarily from lower projected operating results.
		•		Impairment charge of $3.6 million recognized within the Wireless segment based on new market data the Company obtained regarding a facility that is being marketed for sale.
		•		Other impairment charges of $5.7 million recognized in the Wireless segment for certain production equipment and intellectual property that will no longer be utilized.
	In connection with restructuring actions initiated during 2013, the Company recorded pretax impairment charges of $7.8 million related to the planned closure of manufacturing facilities in Joliet, Illinois and Statesville, North Carolina. These facility and equipment impairment charges, described below, are based on Level 3 valuation inputs and are reported in restructuring costs, net on the Consolidated Statement of Operations and Comprehensive Income (Loss).
		•		Facility impairment charge of $1.2 million based on market data the Company received for a facility that will be marketed for sale once manufacturing has been transitioned to other locations or outside contractors.
		•		Equipment impairment charges of $6.6 million related to manufacturing equipment that will no longer be utilized once the Company completes the transition of production.
	Also during 2013, the Company sold certain assets of its BiMetals business. As part of the sale consideration, the Company received a note from the purchaser with a face value of $15.0 million and a term of up to 7 years. The Company recorded the note in other noncurrent assets on the Consolidated Balance Sheet at its estimated fair value of $9.8 million. The valuation supporting the estimated fair value of the note receivable was based on Level 3 valuation inputs.
	During 2012, as a result of reduced expectations of future cash flows of a reporting unit within the Wireless segment, certain intangible assets and property, plant and equipment were determined to be impaired. A pretax impairment charge of $35.0 million was recognized. The fair value measurements related to these asset impairments were generated using a discounted cash flow model and were based on Level 3 valuation inputs. Also during 2012, as a result of a shift in customer demand, the Company determined that the carrying value of certain equipment was no longer recoverable and a pretax impairment charge of $5.9 million was recognized within the Wireless segment. The valuations supporting the equipment impairment charge were based on Level 3 valuation inputs.
	The fair value estimates are based on information available to management as of December 31, 2013 and 2012. 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 subsequent to those dates, and current estimates of fair value may differ significantly from the amounts presented.

Restructuring Costs and Employee Termination Benefits	'
	9	RESTRUCTURING COSTS AND EMPLOYEE TERMINATION BENEFITS
	Prior to the acquisition by Carlyle, the Company had initiated various restructuring actions to realign and lower its cost structure, improve capacity utilization and complete integration efforts related to the Andrew acquisition. To achieve these objectives, the Company announced the closure of manufacturing facilities in Omaha, Nebraska and Newton, North Carolina, among other actions. Beginning in the third quarter of 2011 and continuing through 2013, additional restructuring actions were initiated to realign and lower the Company’s cost structure primarily through workforce reductions at various U.S. and international facilities. In 2013 the Company announced the cessation of manufacturing operations at its Joliet, Illinois and Statesville, North Carolina facilities. Much of the production capacity from these facilities will be shifted to other existing facilities or contract manufacturers. Included in restructuring costs, net for 2013 is a gain of $18.7 million on the sale of certain assets of the BiMetals business, which was part of the Broadband Segment.
	The Company’s net pretax restructuring charges (credits), by segment, were as follows:

	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 cost of unused leased facilities, net of anticipated sub-rental 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 as well as the costs to prepare the receiving facility to accommodate the equipment. Fixed asset related costs also include costs to tear down or enhance current unutilized facilities to improve their use or marketability. These costs are expensed as incurred.
	Asset sale reflects the sale of the certain assets of the Company’s BiMetals business. The Company received $23.0 million in cash and a note with an estimated fair value of $9.8 million as consideration. In addition to $4.7 million of tangible assets, the transaction also included $2.9 million of identified intangible assets and $6.5 million of goodwill. The Company (Broadband Segment) recorded a net gain on the transaction of $18.7 million that was reported in restructuring costs, net on the Consolidated Statement of Operations and Comprehensive Income (Loss).
	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.
	Since the inception of the initiatives begun in 2011, the Company has recognized restructuring charges, net of $63.8 million. The additional pretax costs related to completing restructuring actions initiated to date (primarily relocation and reinstallation of fixed assets) are expected to be approximately $5 million to $6 million, primarily in the Wireless segment. Cash payments of approximately $22 million to $24 million are expected during 2014 with an additional $1 million to $2 million expected to be paid by the end of 2015. Additional restructuring actions may be taken and resulting charges and cash requirements could be material.

Employee Benefit Plans	'
	10	EMPLOYEE BENEFIT PLANS
	Defined Contribution Plans
	The Company sponsors defined contribution retirement savings plans (including a 401(k) plan) that allow employees of certain subsidiaries to contribute a portion of their compensation on a pretax and/or after-tax basis in accordance with guidelines established by the plans and the Internal Revenue Service or other tax authorities. The Company matches a percentage of the employee contributions up to certain limits. During the period January 1 – January 14, 2011 (Predecessor), the Company issued common stock valued at $0.1 million as an employer contribution to the CommScope, Inc. Retirement Savings Plan. During the years ended December 31, 2013 (Successor) and 2012 (Successor) and the period January 15 – December 31, 2011 (Successor), the Company contributed cash of $20.2 million, $18.9 million and $19.8 million, respectively, to these retirement savings plans.
	The Company maintains a noncontributory unfunded defined contribution plan (the Supplemental Executive Retirement Plan or SERP) for certain active and retired executives. The Company is not required to make any payments until the participant is eligible to receive retirement benefits. During the years ended December 31, 2013 (Successor) and 2012 (Successor) and the periods January 15 – December 31, 2011 (Successor) and January 1 – January 14, 2011 (Predecessor), the Company recognized pretax costs of $1.8 million, $1.8 million, $1.4 million and $0.1 million, respectively, representing additional accrued benefits and interest credited under the SERP. The SERP liability was approximately $12.7 million and $11.0 million as of December 31, 2013 and 2012, respectively.
	The Company also established a contributory deferred compensation plan (DCP) in 2013 that allows certain executives to defer up to 90% of salary and bonus. Participant accounts are credited or charged amounts consistent with the investment experience of a notional portfolio (as directed by each executive) based on available investment alternatives in the Company’s 401(k) plan. Upon termination of employment, an executive may elect a lump sum payout or annual installments over two to ten years. As of December 31, 2013, the DCP liability is $1.2 million, which includes an immaterial Company expense related to investment results.
	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. 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 with retirees.
	The following table summarizes information for the defined benefit pension and other postretirement benefit plans based on a December 31 measurement date.

	During 2012, the Company settled a portion of its pension obligation resulting in a settlement loss and terminated a postretirement benefit plan resulting in a settlement gain. During 2013 and 2012, the Company amended certain of its other postretirement benefit plans to eliminate eligibility for certain employees and reduce medical benefits offered under the plans. The impact of the plan amendments is being recognized over the remaining service life of plan participants in plans with active participants and over the life expectancy of plan participants in plans with no active participants.
	The accumulated benefit obligation for all of the Company’s defined benefit pension plans was $276,087 and $269,048 as of December 31, 2013 and 2012, respectively.

The Company considered the available yields on high-quality fixed-income investments with maturities corresponding to the Company’s expected benefit obligations to determine the discount rates at each measurement date.
A one-percentage-point change in assumed health care cost trend rates would have had an immaterial impact on the total service and interest cost components of net periodic benefit cost and the benefit obligation as of and for the year ended December 31, 2013.
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 pension assets are managed by independent investment advisors with an objective of transitioning to a portfolio of fixed income investments that matches the durations of the obligations as the funded status of each plan improves.
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 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, 2013 are as follows:

The Company establishes a valuation allowance when available evidence indicates that it is more likely than not that all or a portion of a deferred tax asset will not be realized.
The deferred tax asset for federal tax credit carryforwards as of December 31, 2013 includes foreign tax credit carryforwards of $114.3 million, which will expire between 2017 and 2023, research tax credit carryforwards of $11.1 million, which will expire between 2028 and 2033 and alternative minimum tax credit carryforwards of $1.7 million with no expiration. A $4.8 million valuation allowance has been established against these deferred tax assets.
The deferred tax asset for state net operating loss and tax credit carryforwards as of December 31, 2013 includes state net operating loss carryforwards (net of federal tax impact) of $14.4 million, which begin to expire in 2014, and state tax credit carryforwards (net of federal tax impact) of $1.0 million which begin to expire in 2014. A valuation allowance of $7.0 million has been established against these state income tax related deferred tax assets.
Deferred tax assets as of December 31, 2013 include $50.5 million of tax benefits associated with foreign net operating loss carryforwards which will expire beginning in 2018. Certain of these foreign net operating loss carryforwards are subject to local restrictions limiting their utilization. As of December 31, 2013 valuation allowances of $43.7 million have been established related to these foreign net operating loss carryforwards.
In addition to the valuation allowances detailed above, the Company has also established a valuation allowance of $14.0 million against other deferred tax assets.
As of December 31, 2013, a deferred tax liability of $35.8 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 $398 million as of December 31, 2013 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:

The Company’s liability for unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate in future periods was $71.6 million as of December 31, 2013. 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 $21.0 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, 2013 and 2012, the Company had accrued $14.0 million and $12.1 million, respectively, for interest and penalties. During the years ended December 31, 2013 and 2012 and the period January 15 – December 31, 2011, the net expense for interest and penalties accrued through income tax expense was $1.9 million, $1.1 million and $1.8 million, respectively.
The Company is currently under examination by the Internal Revenue Service for its U.S. federal income tax return for 2010, as well as amended returns for 2007 and 2008. These examinations are expected to be completed during 2014. The Company files state and local tax returns in multiple jurisdictions with statutes of limitation generally ranging from 3 to 4 years. The Company is generally no longer subject to state and local tax examinations for years prior to 2008. 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 2008. 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.

	12	STOCKHOLDERS’ EQUITY
	Dividends
	On May 28, 2013, a cash dividend of $342.8 million was declared on the Company’s common stock by its Board of Directors and paid. On June 28, 2013, a cash dividend of $195.9 million was declared on the Company’s common stock by its Board of Directors and paid (collectively with the May 28, 2013 dividend, the 2013 dividends). On November 30, 2012, a cash dividend of $200.0 million was declared on the Company’s common stock by its Board of Directors and paid. Although the Company does not intend to pay dividends in the foreseeable future, the payment of any dividends may be limited by covenants under the Company’s senior secured credit facilities and the indentures governing its senior notes.
	In accordance with the antidilution provisions of the Company’s stock incentive plans, the exercise prices of options that were granted following the Carlyle acquisition were adjusted to reflect the 2013 and 2012 dividends. Cash payments of $11.3 million and $0.7 million were made to stock option holders of options granted prior to the Carlyle acquisition in lieu of a reduction in exercise prices, on the 2013 and 2012 dividends, respectively. The cash payments and repricings had no effect on the vesting schedules or expiration dates of the stock options and resulted in no additional compensation expense.
	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, performance units, performance share units, 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 (the 2011 Plan). Awards granted prior to October 24, 2013 remain subject to the provisions of the predecessor plans. Awards granted under the 2011 Plan include stock options and share unit awards for employees and non-employee directors of the Company. Employee stock options and share unit awards generally vest 50% based upon the continued employment of the recipient through the vesting date and 50% based upon the achievement of predetermined financial-based targets. The share unit awards are payable in stock or cash, at the Company’s discretion, and are accounted for as liability awards. As of December 31, 2013, the liability recorded for share unit awards was $10.6 million. Share unit awards that were issued in January 2011 and vested in January 2014 were paid in cash. As of December 31, 2013, 18.6 million shares were available for future grants under the 2013 Plan.
	As of December 31, 2013, $19.1 million of total unrecognized compensation costs related to non-vested stock options and share unit awards are expected to be recognized over a remaining weighted average period of 1.8 years. There were no significant capitalized equity-based compensation costs at December 31, 2013.

	-1	The weighted-average exercise price at December 31, 2013 reflects the adjustment that was made for the 2013 dividends with respect to options granted after the Carlyle acquisition, as described above.
	The total intrinsic value of options exercised during the year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor) and the periods January 15 – December 31, 2011 (Successor) and January 1 – January 14, 2011 (Predecessor) was $2.2 million, $4.2 million, $5.6 million and $0.3 million, respectively.

	$2.96 to $8.90			10,828			6.8		$	6.15			5,923	$	6.15
	The weighted average remaining contractual life of exercisable options at December 31, 2013 was 5.6 years.
	The Company uses the Black-Scholes model to estimate the fair value of stock option awards. Key input assumptions used in the model to estimate the fair value of stock options include the grant price of the award, the expected option term, volatility of the Company’s stock, the risk-free interest rate and the Company’s projected dividend yield. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in estimating the fair values of CommScope stock options. Estimates of fair value are not intended to predict actual future events or the value that will ultimately be realized by employees who receive equity awards, and 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 (No options were granted following the IPO in 2013):
			Successor			Successor			Successor
			Year Ended			Year Ended			January 15 -
			December 31, 2013			December 31, 2012			December 31, 2011

	Expected dividend yield			0	%		0	%		0	%
	Weighted average fair value at grant date		$	4.69		$	3.24		$	3.96
	Restricted Stock Units
	Restricted Stock Unit Awards (RSUs) entitle the holder to shares of common stock after a one-year vesting period. The fair value of the awards is determined on the grant date based on the Company’s stock price.
	The following table summarizes the RSU activity for the year ended December 31, 2013 (in thousands, except per share data):
	Successor		Restricted			Weighted Average
			Stock Units			Grant Date Fair

	During the period January 1 – January 14, 2011 (Predecessor), the Company issued common stock valued at $0.1 million, respectively, as employer contributions to the CommScope, Inc. Retirement Savings Plan. The issuance of these shares, along with share unit award expense of $5.5 million, $3.5 million and $1.5 million for the years ended December 31, 2013 (Successor), December 31, 2012 (Successor) and the period January 15 – December 31, 2011 (Successor), respectively, is included in equity-based compensation as an adjustment to reconcile net income (loss) to net cash provided by (used in) operating activities on the Consolidated Statements of Cash Flows.

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.

Basis of Consolidation

'

Basis of Consolidation

The accompanying consolidated financial statements include CommScope Holding Company, Inc., along with its direct and indirect subsidiaries (CommScope or the Company). All intercompany accounts and transactions are eliminated in consolidation.

As a result of the application of acquisition accounting in 2011, the assets and liabilities of CommScope, Inc. were adjusted to their estimated fair values as of the closing date of the acquisition. Accordingly, the accompanying consolidated financial statements are presented separately for Predecessor and Successor accounting periods, which relate to the accounting periods preceding and succeeding the completion of the acquisition. The Predecessor and Successor periods have been separated by a vertical line on the face of the consolidated financial statements to highlight the fact that the financial information for such periods has been prepared under two different historical cost bases of accounting.

Certain prior year amounts have been reclassified to conform to the current year presentation.

Allowance for Doubtful Accounts

'

Allowance for Doubtful Accounts

The Company maintains allowances for doubtful accounts for estimated losses expected to result from the inability of its customers to make required payments. These estimates are based on management’s evaluation of the ability of customers to make payments, focusing on historical experience, known customer financial difficulties and age of receivable balances.

Inventories

'

Inventories

Inventories are stated at the lower of cost or market. Inventory cost is determined on a first-in, first-out (FIFO) basis. Costs such as idle facility expense, excessive scrap and rehandling costs are recognized as expenses as incurred. The Company maintains reserves to reduce the value of inventory to the lower of cost or market, including reserves for excess and obsolete inventory.

Long-Lived Assets

'

Long-Lived Assets

Property, Plant and Equipment

Property, plant and equipment are stated at cost, including interest costs associated with qualifying capital additions. Upon application of acquisition accounting, property, plant and equipment were 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 charged to expense 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 $36.2 million and $80.2 million were recorded in 2013 and 2011, 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 2013, 2012 and 2011, the Company recognized pretax impairment charges other than goodwill impairments of $9.3 million, $40.9 million and $45.9 million, respectively. See Notes 4 and 8 for further discussion of these impairment charges.

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 $398 million as of December 31, 2013. 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 income (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.

Certain revenue arrangements are for the sale of software and services. Revenue for software products is recognized based on the timing of customer acceptance of the specific revenue elements. The fair value of each revenue element is determined based on vendor-specific objective evidence of fair value determined by stand-alone pricing of each element. These contracts typically contain post-contract support (PCS) services which are sold both as part of a bundled product offering and as a separate contract. Revenue for PCS services is recognized ratably over the term of the PCS contract. Other service revenue is typically recognized once the service is performed or over the period of time covered by the arrangement.

For sales to distributors, system integrators and value-added resellers (primarily for the Enterprise segment), revenue is recorded at the net amount to be received after deductions for estimated discounts, allowances, returns and rebates. 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.

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 $27.3 million, $25.2 million, $20.5 million and $0.8 million for the year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2011 (Predecessor).

Advertising Costs

'

Advertising Costs

Advertising costs are expensed in the period in which they are incurred. Advertising expense was $10.3 million, $7.7 million, $9.5 million and $0.4 million for the year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2011 (Predecessor).

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 and non-derivative financial instruments 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 purposes, nor does it allow for speculation. A hedging instrument may be designated as a net investment hedge to manage exposure to foreign currency risks related to an investment in a foreign subsidiary; a fair value hedge to manage exposure to risks related to a foreign-currency-denominated cash or other account or a firm commitment for the purchase of raw materials or equipment; or a cash flow hedge to manage exposure to risks related to a forecasted purchase of raw materials, variable interest rate payments or a forecasted foreign-currency-denominated sale of product. The use of non-derivative financial instruments in hedging activities is limited to hedging fair value risk related to a foreign-currency-denominated firm commitment or a foreign currency risk related to a net investment in a foreign subsidiary.

The Company’s risk management strategy permits the reasonable and practical use of derivative hedging instruments such as forward contracts, options, cross currency swaps, certain interest rate swaps, caps and floors, and non-derivative hedging instruments such as foreign-currency-denominated loans. The Company recognizes all derivative financial instruments as assets or liabilities and measures them at fair value. All hedging instruments are designated and documented as a fair value hedge, a cash flow hedge or a net investment hedge at inception. For fair value hedges, the change in fair value of the derivative instrument is recognized currently in earnings. To the extent the fair value hedging relationship is effective, the change in fair value of the hedged item is recorded as an adjustment to the carrying amount of the hedged item and recognized currently in earnings. For cash flow hedges, the effective portion of the change in fair value of the derivative instrument is recorded in accumulated other comprehensive income (loss), net of tax, and is recognized in the consolidated statements of operations and comprehensive income (loss) when the hedged item affects earnings. Any ineffectiveness of a cash flow hedge is recognized currently in earnings. For net investment hedges, the effective portion of the change in fair value of a derivative instrument, or the change in carrying amount of a non-derivative instrument, is recorded in accumulated other comprehensive income (loss), net of tax, and is recognized in the consolidated statements of operations and comprehensive income (loss) only if there is a substantially complete liquidation of the investment in the foreign subsidiary. Any ineffectiveness of a net investment hedge is recognized currently in earnings. The effectiveness of designated hedging relationships is tested and documented on at least a quarterly basis.

In the Predecessor period of January 2011, the Company settled an interest rate swap liability that had been designated as a cash flow hedge to mitigate the cash flow effects of interest rate fluctuations on interest expense for a portion of its variable-rate debt instruments.

The Company also uses derivative instruments such as forward exchange contracts to manage the risk of foreign currency fluctuations. These instruments are not leveraged and are not held for trading or speculation. These contracts are not designated as hedges for accounting purposes and are marked to market each period through earnings and, as such, there were no unrecognized gains or losses as of December 31, 2013 or 2012. 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 year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2011 (Predecessor), approximately 45%, 47%, 49% and 49%, respectively, of the Company’s net sales were to customers located outside the U.S. A portion of these sales were denominated in currencies other than the U.S. dollar, particularly sales from the Company’s foreign subsidiaries. The financial position and results of operations of certain of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Revenues and expenses of these subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities of these subsidiaries have been translated at the exchange rates as of the balance sheet date. Translation gains and losses are recorded to accumulated other comprehensive income (loss).

Aggregate foreign currency transaction gains and losses of the Company and its subsidiaries, such as those resulting from the settlement of receivables or payables 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 $9.8 million, $7.0 million, $8.9 million and $1.1 million during the year ended December 31, 2013 (Successor), the year ended December 31, 2012 (Successor), the period January 15 – December 31, 2011 (Successor) and the period January 1 – January 14, 2001 (Predecessor), respectively. Foreign currency remeasurement gains and losses related to long-term intercompany loans that are not expected to be settled in the foreseeable future are recorded to accumulated other comprehensive income (loss).

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).

Tax benefits of $5.3 million resulting from the exercise of stock options that were vested as of the adoption of ASC Topic 718 Compensation—Stock Compensation were classified as financing cash inflows for the period January 1 – January 14, 2011 (Predecessor).

Common Stock, Preferred Stock and Stock Split

'

Common Stock, Preferred Stock and Stock Split

On October 4, 2013, the Company’s Board of Directors approved a 3-for-1 stock split of the Company’s outstanding common stock, which was effective as of October 4, 2013. Each share of issued and outstanding common stock was increased to 3 shares of common stock, the number of shares of common stock into which each outstanding option to purchase stock is exercisable was proportionally increased on a 3-for-1 basis, and the exercise price of each outstanding option to purchase common stock was proportionally decreased. All of the Successor period share numbers, share prices, exercise prices and other per share information throughout these financial statements have been adjusted on a retroactive basis, to reflect this 3-for-1 stock split, including reclassifying an amount equal to the increase in par value from additional paid-in capital. In conjunction with the Company’s IPO in October 2013, the Company’s Board of Directors authorized 1.3 billion shares of common stock, par value $0.01 per share and 0.2 billion shares of preferred stock, par value $0.01 per share.

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.

For the Predecessor period, diluted earnings (loss) per share is based on net income (loss) adjusted for after-tax interest and amortization of debt issuance costs related to convertible debt, if dilutive, divided by the weighted average number of common shares outstanding adjusted for the dilutive effect of stock options, restricted stock units, performance share units and convertible securities.

For the Successor periods diluted earnings (loss) per share is based on net income (loss) divided by the weighted average number of common shares outstanding adjusted for the dilutive effect of stock options.

Below is a reconciliation of earnings and weighted average common shares and potential common shares outstanding for calculating diluted earnings (loss) per share.

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.

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, 2013, 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, brass, 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.
