Summary of Significant Accounting Policies

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.

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 $4.9 million and $36.2 million were recorded during the years ended December 31, 2014 and 2013, respectively. See Notes 4 and 8 for further discussion of these impairment charges.

Property, plant and equipment and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, based on the undiscounted cash flows expected to be derived from the use and ultimate disposition of the assets. Assets identified as impaired are carried at estimated fair value. During the years ended December 31, 2014, 2013 and 2012, the Company recognized pretax impairment charges, other than goodwill impairments, of $7.2 million, $9.3 million and $40.9 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 $441 million as of December 31, 2014. 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. Such revisions may be material.

Shipping and Handling Costs

CommScope includes shipping and handling costs billed to customers in net sales and includes the costs incurred to transport product to customers as cost of sales. Certain internal handling costs, which relate to activities to prepare goods for shipment, are recorded in selling, general and administrative expense and were approximately $27.2 million, $27.3 million and $25.2 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Advertising Costs

Advertising costs are expensed in the period in which they are incurred. Advertising expense was $10.5 million, $10.3 million and $7.7 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Research and Development

Research and development (R&D) costs are expensed in the period in which they are incurred. R&D costs include materials and equipment that have no alternative future use, depreciation on equipment and facilities currently used for R&D purposes, personnel costs, contract services and reasonable allocations of indirect costs, if clearly related to an R&D activity. Expenditures in the pre-production phase of an R&D project are recorded as R&D expense. However, costs incurred in the pre-production phase that are associated with output actually used in production are recorded in cost of sales. A project is considered finished with pre-production efforts when management determines that it has achieved acceptable levels of scrap and yield, which vary by project. Expenditures related to ongoing production are recorded in cost of sales.

Derivative Instruments and Hedging Activities

CommScope is exposed to risks resulting from adverse fluctuations in commodity prices, interest rates and foreign currency exchange rates. CommScope’s risk management strategy includes the use of derivative 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. The Company did not designate any transactions as hedges in the years ended December 31, 2014, 2013 or 2012.

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, 2014 or 2013. See Note 7 for further disclosure related to the derivative instruments and hedging activities.

The Company has elected and documented the use of the normal purchases and sales exception for normal purchase and sales contracts that meet the definition of a derivative financial instrument.

Foreign Currency Translation

For the years ended December 31, 2014, 2013 and 2012, approximately 45%, 45% and 47%, 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 $2.7 million, $9.8 million and $7.0 million during the years ended December 31, 2014, 2013 and 2012, 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 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).

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 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 initial public offering in October 2013, the Company’s Board of Directors authorized 1.3 billion shares of common stock, par value $0.01 per share and 200 million shares of preferred stock, par value $0.01 per share.

Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on net income divided by the weighted average number of common shares outstanding plus the dilutive effect of potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding equity-based awards (stock options and restricted stock units). Certain outstanding equity-based awards were not included in the computation of diluted earnings per share because the effect was either antidilutive or the performance condition was not met (1.4 million, 2.2 million and 6.9 million shares for the years ended December 31, 2014, 2013 and 2012, respectively).

The following table presents the basis for the earnings per share computations:

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, 2014, 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.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, which establishes a single comprehensive model for revenue recognition. Under the new guidance, revenue will be recognized when control over goods or services has been transferred to a customer. When multiple goods or services are sold under a single arrangement, revenue will be allocated based on the relative standalone selling prices of the various elements. The Company will be required to adopt the standard as of January 1, 2017 and early adoption is not permitted. Transition alternatives include full retrospective adoption or a modified retrospective adoption. The Company has not determined the transition approach that will be utilized or estimated the impact of adopting the new accounting standard.

ACQUISITIONS AND DIVESTITURES

Acquisitions

Alifabs Group

In July 2014, the Company acquired two businesses of United Kingdom-based Alifabs Group (Alifabs) for $48.8 million ($46.7 million, net of cash acquired). Alifabs is a designer and supplier of enclosures, monopoles, smaller streetworks towers and tower solutions for the United Kingdom telecommunications, utility and energy markets. Sales of Alifabs products reflected in the Consolidated Statements of Operations and Comprehensive Income were $25.2 million for the year ended December 31, 2014.

The preliminary allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows (in millions):


	Estimated Fair Value
Cash and cash equivalents	$	2.1
Other current assets		15.7
Identifiable intangible assets		26.9
Goodwill		15.3
Other noncurrent assets		0.6
Less: Liabilities assumed		(11.8	)

Net acquisition cost	$	48.8

The goodwill arising from the purchase price allocation of the Alifabs acquisition is believed to result from the company’s reputation in the marketplace and assembled workforce and is not expected to be deductible for income tax purposes.

As additional information is obtained, adjustments may be made to the preliminary purchase price allocation. The Company is still finalizing the estimated fair value of certain of the tangible and intangible assets acquired.

Redwood Systems, Inc.

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 of $12.4 million as of the acquisition date. 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. During the year ended December 31, 2014, the estimated fair value of the liability for contingent consideration was reduced to zero (see Note 8). In addition, there are potential retention payments for employees of Redwood of up to $11.75 million based on the same net sales targets as the contingent consideration. The Company believes that the likelihood is remote that any of the retention payments will be made. Redwood is a component of the Enterprise segment.

The allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows (in millions):


	Estimated Fair Value
Current assets	$	2.6
Deferred taxes		7.3
Other intangible assets		9.0
Goodwill		4.2
Other noncurrent assets		0.8
Less: Liabilities assumed		(1.7	)

Net acquisition cost	$	22.2

The goodwill arising from the 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 income tax purposes.

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. In March 2014, the Company reached an agreement with the former owners of iTRACS to adjust the purchase price by $4.7 million and that amount was received by the Company in April 2014. iTRACS develops and markets enterprise-class data center infrastructure management (DCIM) solutions. iTRACS is a component of the Enterprise segment.

The allocation of the purchase price, based on the estimated fair values of assets acquired and liabilities assumed, is as follows (in millions):


	Estimated Fair Value
Current assets	$	1.7
Noncurrent assets, excluding intangible assets		0.7
Other intangible assets		13.1
Goodwill		15.1
Less: Liabilities assumed		(1.3	)

Net acquisition cost	$	29.3

The goodwill arising from the purchase price allocation of the iTRACS acquisition is believed to result from iTRACS’ reputation in the marketplace and assembled workforce and is expected to be deductible for income tax purposes.

Argus Technologies

In 2013, the Company made the final payment of $12.0 million for the 2011 acquisition of Argus Technologies.

Divestitures

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 Statements of Operations and Comprehensive Income. The gain on sale is reported in the Broadband segment.

Other

During the year ended December 31, 2012, the Company sold its filter manufacturing facility in Shenzhen, China for $6.9 million, net of cash sold, of which $4.0 million was received in the year ended December 31, 2012 and $2.9 million in the year ended December 31, 2013. A gain of $1.5 million was recorded in the year ended December 31, 2012 related to the sale.

Total intangible assets	$	1,960.5	$	699.6	$	1,260.9	$	1,943.8	$	521.6	$	1,422.2

During 2014, as a result of reduced expectations of future cash flows of a product line in the Broadband Segment, certain intangible assets were determined to be impaired. A pretax charge of $7.2 million was recognized, which consisted of $2.6 million of customer base, $0.2 million of trade names and trademarks, and $4.4 million of patents and technologies intangible assets (recorded in other expense, net, on the Consolidated Statements of Operations and Comprehensive Income).

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.


	Weighted- Average Amortization Period
	(in years)
Customer base		10.1
Trade names and trademarks		19.8
Patents and technologies		6.7
Non-compete agreements		4.0

Amortization expense for intangible assets was $178.3 million, $174.9 million and $175.7 million for the years ended December 31, 2014, 2013 and 2012, respectively. Estimated amortization expense for the next five years is as follows (in millions):

During 2014, management determined that an indicator of possible impairment existed for the Microwave Antenna Group (Microwave) reporting unit in the Wireless segment, as a result of lower than expected levels of sales and operating income during 2014 and the effect of market conditions on the projected future operations of the business. 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 used for the Microwave reporting unit valuation was 11.0% compared to 11.5% in the 2013 annual test and was based on the estimated weighted average cost of capital as of the test date for market participants in the industry in which the Microwave reporting unit operates. Based on the estimated fair values generated by the DCF model, the Microwave reporting unit did not pass step one of the goodwill impairment test. A step two analysis was performed and a goodwill impairment charge of $4.9 million was recorded. The goodwill impairment charge resulted primarily from lower projected operating results than those used in the 2013 annual impairment test.

During 2013, a goodwill impairment charge of $36.2 million was recorded in the Broadband reporting unit using a DCF model. The discount rate used was 11.0% compared to 11.5% used in the 2012 annual test.

Investments

The Company utilizes the equity method of accounting for investments in entities where it does not have control but has the ability to exercise significant influence over the investee’s operating and financial policies. The Company considers investments in publicly traded securities for which it does not have significant influence as available-for-sale. Available-for-sale securities are carried at fair value with changes in fair value recorded, net of tax, in other comprehensive income (loss). As of December 31, 2014, the Company owned 1.5 million shares of Hydrogenics Corporation (Hydrogenics), a publicly traded company that supplies hydrogen generators and hydrogen-based power modules and fuel cells for various uses. During the year ended December 31, 2014, the Company reduced its ownership in Hydrogenics and no longer has significant influence over the investee’s operating and financial policies. As a result, the Company changed its method of accounting from the equity method to classifying the investment as available-for-sale. The Company’s share of losses in investments accounted for as equity method investments were $1.5 million, $1.4 million and $3.4 million for the years ended December 31, 2014, 2013 and 2012, respectively.

As of December 31, 2014, the cost basis of the investment in Hydrogenics was $1.2 million, the fair value was $20.4 million and the unrealized pretax gain recorded in accumulated other comprehensive income (loss) was $19.2 million ($11.9 million, net of tax). The Company did not hold any investments that were classified as available-for-sale as of December 31, 2013. As of December 31, 2013 the carrying value of the Hydrogenics investment, accounted for under the equity method, was $3.1 million. Investments are recorded in other noncurrent assets on the Consolidated Balance Sheets.

During the year ended December 31, 2014, the Company sold 0.7 million shares of Hydrogenics common stock, and received proceeds of $10.3 million. Using the average cost method to value the shares sold, the Company recorded pretax realized gains of $9.8 million for the year ended December 31, 2014 (recorded in other expense, net on the Consolidated Statements of Operations and Comprehensive Income). No available-for-sale securities were sold during the years ended December 31, 2013 or 2012.

5.00% Senior Notes Due 2021 and 5.50% Senior Notes Due 2024

In May 2014, CommScope, Inc., a direct wholly owned subsidiary of the Company, issued $650.0 million of 5.00% Senior Notes due June 15, 2021 (the 2021 Notes) and $650.0 million of 5.50% Senior Notes due June 15, 2024 (the 2024 Notes), collectively referred to as the New Notes. Interest is payable on the New Notes semi-annually in arrears on June 15 and December 15 of each year.

Proceeds from the New Notes were used to redeem the entire outstanding amount of the 8.25% senior notes due January 2019 (the 2019 Notes) plus pay a redemption premium of $93.9 million, which was included in other expense, net for the year ended December 31, 2014. The remainder of the net proceeds was available for general corporate purposes. In connection with the redemption of the 2019 Notes, the Company wrote off $19.1 million of deferred financing costs to interest expense during the year ended December 31, 2014.

Each of the Company’s existing and future direct and indirect domestic subsidiaries that guarantees the senior secured credit facilities guarantees the New Notes on a senior unsecured basis. The New Notes and the guarantees are unsecured senior obligations ranking equal in right of payment to all of the Company’s and the guarantors’ existing and future senior indebtedness, including its senior secured credit facilities. However, the New Notes and guarantees are effectively junior 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 New Notes are structurally subordinated to all existing and future liabilities (including trade payables) of the Company’s subsidiaries that do not guarantee the New Notes, including indebtedness incurred by certain of the Company’s non-U.S. subsidiaries under the revolving credit facility.

The New Notes may be redeemed prior to maturity under certain circumstances. Upon certain change of control events, the New Notes may be redeemed at the option of the holders at 101% of their face amount, plus accrued and unpaid interest to the date of purchase. Prior to June 15, 2017 in the case of the 2021 Notes and June 15, 2019 in the case of the 2024 Notes, the New Notes may be redeemed at a redemption price equal to 100% of their principal amount, plus a make-whole premium (as defined in the indentures governing the New Notes), plus accrued and unpaid interest to the redemption date. On or prior to June 15, 2017, under certain circumstances, we may also redeem up to 40% of the aggregate principal amount of each series of the New Notes at a redemption price of 105.0% in the case of the 2021 Notes or 105.5% in the case of the 2024 Notes, plus accrued and unpaid interest to the redemption date using the proceeds of certain equity offerings.

In connection with issuing the New Notes, the Company incurred costs of approximately $23.3 million during the year ended December 31, 2014, which were capitalized as other noncurrent assets and are being amortized over the terms of the notes.

Senior Secured Credit Facilities

The Company’s senior secured credit facilities consist of an $875 million term loan facility and a $400 million asset-based revolving credit facility, of which $864.1 million was outstanding under the term loan facility and no borrowings were outstanding under the asset-based revolving credit facility as of December 31, 2014. 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.

The senior secured term loan consists of two tranches, one of which is due January 2017 (the 2017 term loan) and the other is due January 2018 (the 2018 term loan). The interest rate margin applicable to the 2017 and 2018 term 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, twelve-month LIBOR (selected at the Company’s option) plus a margin of 2.50%. There is a LIBOR floor of 0.75% with respect to the 2018 term loan.

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, 2014, 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 ranges from an annual rate of 0.250% to 0.375% based on usage of the facility. As of December 31, 2014, the rate was 0.375%.

During 2014, the Company borrowed and repaid $15.0 million under the revolving credit facility and made scheduled repayments of $8.8 million of its senior secured term loans. As of December 31, 2014, the Company had remaining availability of approximately $321.7 million under the asset-based revolving credit facility, reflecting a borrowing base of $345.3 million reduced by $23.6 million of letters of credit issued under the revolving credit facility.

During 2013 and 2012, the Company amended its senior secured credit facilities. In connection with the 2013 amendments and a voluntary $100.0 million term loan payment made during 2013, $1.4 million of original issue discount and $2.0 million of deferred financing costs were written off and included in interest expense for 2013. As a result of the 2012 amendments, $0.5 million of original issue discount and $2.6 million of deferred financing fees were written off and included in interest expense for 2012. The amendments in 2013 and 2012 resulted in the repayment of $172.3 million and $104.6 million, respectively, to certain lenders under the senior secured credit facilities and the receipt of $172.3 million and $104.6 million, respectively, in proceeds from new lenders and existing lenders who increased their positions.

The Company also incurred pretax costs of $3.3 million and $1.7 million during 2013 and 2012, respectively, which were included in other expense, net on the Consolidated Statements of Operations and Comprehensive Income (Loss) and in long-term debt financing costs on the Consolidated Statements of Cash Flows. In addition, upfront fees of $10.4 million paid to lenders and other financing costs of $1.0 million that were incurred in connection with the 2012 amendments were recorded as original issue discount during 2012 and are being amortized over the terms of the facilities.

Senior PIK Toggle Notes

In May 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. 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. The interest payments on the senior PIK toggle notes during the years ended December 31, 2014 and 2013 were paid in cash.

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, 2014, 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.

Other Matters

The following table summarizes scheduled maturities of long-term debt as of December 31, 2014 (in millions):

Derivatives and Hedging Activities

DERIVATIVES AND HEDGING ACTIVITIES

The Company uses forward contracts to hedge a portion of its exposure to balances denominated in currencies other than the functional currency of various subsidiaries and to manage exposure to certain planned foreign currency expenditures in order to mitigate the impact of changes in exchange rates. At December 31, 2014, the Company had foreign exchange contracts with maturities ranging from one to nine months with an aggregate notional value of $363 million (based on exchange rates as of December 31, 2014). 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 Disclosures [Abstract]

Fair Value Measurements

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, investment in equity securities, debt instruments, foreign currency contracts and contingent consideration payable. For cash and cash equivalents, trade receivables and trade payables, the carrying amounts of these financial instruments as of December 31, 2014 and December 31, 2013 were considered representative of their fair values due to their short terms to maturity. The fair value of the Company’s investment in equity securities is based on quoted market prices. The fair values of the Company’s debt instruments and foreign currency contracts were based on indicative quotes. The fair value of the contingent consideration payable was based on a probability weighted discounted cash flow analysis.

The carrying amounts, estimated fair values and valuation input levels of the Company’s investment in equity securities, foreign currency contracts, senior notes, senior secured term loans, senior PIK toggle notes and contingent consideration payable as of December 31, 2014 and December 31, 2013, are as follows:


	December 31, 2014				December 31, 2013
	Carrying Amount		Fair Value		Carrying Amount		Fair Value		Valuation Inputs
Assets:
Investment in equity securities	$	20,392	$	20,392	$	3,112	$	41,879		Level 1
Foreign currency contracts		1,165		1,165		2,738		2,738		Level 2
Liabilities:
5.00% senior notes due 2021		650,000		643,500		—		—		Level 2
5.50% senior notes due 2024		650,000		640,250		—		—		Level 2
8.25% senior notes		—		—		1,100,000		1,205,280		Level 2
Senior secured term loans due 2017, at par		345,625		342,169		349,125		349,997		Level 2
Senior secured term loans due 2018, at par		518,438		513,254		523,688		524,997		Level 2
Senior PIK toggle notes due 2020		550,000		566,500		550,000		572,000		Level 2
Foreign currency contracts		3,584		3,584		662		662		Level 2
Contingent consideration		—		—		13,068		13,068		Level 3

Contingent consideration represents the estimated fair value of the expected 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. During the year ended December 31, 2014, the estimated fair value of the contingent consideration was reduced to zero based on revenue projections for the requisite periods, which resulted in a $13.1 million reduction in selling, general and administrative expense in the Consolidated Statements of Operations and Comprehensive Income.

Non-Recurring Fair Value Measurements

During the year ended December 31, 2014, the Company recorded impairment charges of $12.2 million. The valuations supporting the following pretax impairment charges are based on level 3 valuation inputs.

•

Goodwill impairment charge of $4.9 million related to the Wireless segment.

•

Impairment charge of $7.2 million to reduce certain intangible assets in the Broadband segment to their estimated fair value.

In connection with restructuring actions during the year ended December 31, 2014, the Company recorded a pretax charge of $8.1 million related to the unused portion of its leased facility in Joliet, Illinois, that is currently available for sublease. This charge was based on level 3 valuation inputs and recorded in restructuring costs, net on the Consolidated Statements of Operations and Comprehensive Income.

During the year ended December 31, 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.

•

Impairment charge of $3.6 million recognized within the Wireless segment 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 the year ended December 31, 2013, the Company recorded pretax impairment charges of $7.8 million related to the planned cessation of manufacturing at 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 Statements of Operations and Comprehensive Income.

•

Facility impairment charge of $1.2 million based on market data the Company received for a facility that is being marketed for sale.

•

Equipment impairment charges of $6.6 million related to manufacturing equipment that was no longer being utilized.

Also during the year ended December 31, 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.

These fair value estimates are based on pertinent information available to management as of the date made. Although management is not aware of any factors that would significantly affect these fair value estimates, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates and current estimates of fair value may differ significantly from the amounts presented.

Restructuring Costs and Employee Termination Benefits

RESTRUCTURING COSTS AND EMPLOYEE TERMINATION BENEFITS

The Company has initiated restructuring actions to realign and lower its cost structure primarily through workforce reductions and other cost reduction initiatives at various facilities, including the cessation of manufacturing operations at the Joliet, Illinois; Statesville, North Carolina; and Guangzhou, China facilities. Much of the production capacity from these facilities is being shifted to other existing facilities or unaffiliated suppliers. The Company’s net pretax restructuring charges (credits), by segment, were as follows:


	Year Ended December 31,
	2014		2013			2012
Wireless	$	16,191	$	24,306		$	21,859
Enterprise		147		5,094			311
Broadband		2,929		(7,296	)		823

Total	$	19,267	$	22,104		$	22,993

The activity within the liability established for these restructuring actions was as follows:


	Employee- Related Costs			Lease Termination Costs			Fixed Asset Related Costs			BiMetals Asset Sale			Total

Employee-related costs include the expected severance costs and related benefits as well as one-time severance benefits that are accrued over the remaining period employees are required to work in order to receive such benefits.

Lease termination costs relate to the discounted cost of unused leased facilities, net of anticipated sub-rental income.

Fixed asset related costs include non-cash impairments or disposals of fixed assets associated with restructuring actions in addition to the cash costs to uninstall, pack, ship and reinstall manufacturing equipment and the costs to prepare the receiving facility to accommodate relocated equipment. These costs are expensed as incurred. Cash paid is net of proceeds received from the sale of related assets.

BiMetals asset sale activity reflects the 2013 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. Within its Broadband segment, the Company recorded a net gain on the transaction of $18.7 million that was reported in restructuring costs, net on the Consolidated Statements of Operations and Comprehensive Income.

As a result of restructuring and consolidation actions, the Company owns unutilized real estate at various facilities in the U.S. and internationally. The Company is attempting to sell or lease this unutilized space. Additional impairment charges may be incurred related to these or other excess assets.

The Company has recognized restructuring charges of $83.1 million since January 2011. Additional pretax costs of approximately $1.0 million to $2.0 million are expected to complete these initiatives. Cash payments of approximately $5.0 million to $6.0 million are expected to be paid by the end of 2015 with additional payments of $7.0 million to $9.0 million to be paid between 2016 and 2022. Additional restructuring actions may be taken and the resulting charges and cash requirements could be material.

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 years ended December 31, 2014, 2013 and 2012, the Company contributed cash of $19.6 million, $20.2 million and $18.9 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, 2014, 2013 and 2012, the Company recognized pretax costs of $2.0 million, $1.8 million, $1.8 million, respectively, representing additional accrued benefits and interest credited under the SERP. The SERP liability was approximately $13.0 million and $12.7 million as of December 31, 2014 and 2013, 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, 2014 and 2013, the DCP liability was $4.2 million and $1.2 million, respectively.

Pension and Other Postretirement Benefit Plans

The Company sponsors defined benefit pension plans covering certain domestic former employees and certain foreign current and former employees. 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 2013, 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 $283,053 and $261,217 as of December 31, 2014 and 2013, respectively.

Assumptions

Significant weighted average assumptions used in determining benefit obligations and net periodic benefit cost are as follows:


	Pension Benefits
	2014			2013			2012
Benefit obligations:
Discount rate		3.80	%		4.70	%		4.10	%
Rate of compensation increase		4.00	%		4.30	%		3.90	%
Net periodic benefit cost:
Discount rate		4.70	%		4.10	%		4.50	%
Rate of return on plan assets		5.45	%		5.60	%		5.55	%
Rate of compensation increase		4.30	%		3.90	%		4.00	%


	Other Postretirement Benefits
	2014			2013			2012
Benefit obligations:
Discount rate		3.15	%		3.50	%		2.65	%
Net periodic benefit cost:
Discount rate		3.50	%		2.65	%		4.20	%
Health care cost trend rate assumed for next year		7.25	%		7.25	%		7.35	%
Ultimate rate to which the cost trend rate is assumed to decline		4.75	%		4.75	%		4.75	%
Year that the rate reaches the ultimate trend rate		2023			2023			2022

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, 2014.

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, 2014 are as follows:


	Pension Benefits				Other Postretirement Benefits
	Level 1 Fair Value		Level 2 Fair Value		Level 1 Fair Value		Level 2 Fair Value

Other		1,404		103		—		—

Total	$	160,325	$	147,324	$	1,543	$	—

The estimated fair values and the valuation input levels of the Company’s plan assets as of December 31, 2013 are as follows:

Expected Cash Flows

The Company expects to contribute $14.2 million to the defined benefit pension plans and $3.0 million to the other postretirement benefit plans during 2015.

The following table summarizes projected benefit payments from pension and other postretirement benefit plans through 2024, including benefits attributable to estimated future service (in millions):

On January 2, 2013, the American Taxpayer Relief Act of 2012 retroactively extended the tax credit for research and experimentation expenses through December 31, 2013. The Company has reflected the 2012 credit in its 2013 tax provision, resulting in a benefit of $1.8 million.

The Company adopted accounting guidance as of January 1, 2014 that requires an entity to net its liability for uncertain tax positions as a reduction to deferred tax assets related to net operating loss carryforwards, similar tax losses or tax credit carryforwards when settlement in this manner is available under tax law. The impact of adopting this new guidance was immaterial.

The deferred tax asset for federal tax credit carryforwards as of December 31, 2014 relates to tax credit carryforwards that expire between 2018 and 2023.

The deferred tax asset for state net operating loss and tax credit carryforwards as of December 31, 2014 includes state net operating loss carryforwards (net of federal tax impact) of $16.1 million, which begin to expire in 2015, and state tax credit carryforwards (net of federal tax impact) of $0.9 million which begin to expire in 2015. A valuation allowance of $11.4 million has been established against these state income tax related deferred tax assets.

Deferred tax assets as of December 31, 2014 include $40.4 million of foreign net operating loss carryforwards (tax effected) 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, 2014 valuation allowances of $40.0 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 $15.2 million against other deferred tax assets.

As of December 31, 2014, a deferred tax liability of $23.1 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 $441 million as of December 31, 2014 as these earnings are considered to be permanently reinvested in foreign operations. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.

The following table reflects a reconciliation of the beginning and end of period amounts of gross unrecognized tax benefits, excluding interest and penalties:


	Year Ended December 31,
	2014			2013			2012
Balance at beginning of period	$	91,410		$	92,523		$	95,013

Decrease related to settlement with taxing authorities		—			—			(5,928	)
Decrease related to lapse in statutes of limitations		(22,135	)		(959	)		(1,742	)

Balance at end of period	$	68,223		$	91,410		$	92,523

The Company’s liability for unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate in future periods was $50.9 million as of December 31, 2014. 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 $5.0 million within the next twelve months.

The Company provides for interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2014 and 2013, the Company had accrued $8.3 million and $14.0 million, respectively, for interest and penalties. During the years ended December 31, 2014, 2013 and 2012, the net expense (credit) for interest and penalties recognized through income tax expense was $(4.6) million, $1.9 million and $1.1 million, respectively.

During 2014, the Company concluded an examination by the Internal Revenue Service of the Company’s U.S. federal income tax return for 2010, as well as amended returns for 2007 and 2008. 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 2009. 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 2009. In many jurisdictions, tax authorities retain the ability to review prior years’ tax returns and to adjust any net operating loss or tax credit carryforwards from these years that are available to be utilized in subsequent periods. During 2014, the Company recognized $22.1 million related to the lapse of applicable statutes of limitations and the conclusion of various domestic and foreign examinations.

STOCKHOLDERS’ EQUITY

Dividends

On May 28, 2013, a cash dividend of $342.8 million ($2.21 per share) 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 ($1.26 per share) 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 ($1.29 per share) 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 (RSUs), 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, 2014, the liability recorded for share unit awards was $10.1 million. Share unit awards of $4.7 million that were issued in January 2011 and vested in January 2014 were paid in cash. As of December 31, 2014, 17.5 million shares were available for future grants under the 2013 Plan.

As of December 31, 2014, $15.0 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 1.4 years. There were no significant capitalized equity-based compensation costs at December 31, 2014.

Stock options

The following table summarizes the stock option activity (in thousands, except per share amounts):


	Shares			Weighted Average Option Exercise Price Per Share		Weighted Average Grant Date Fair Value Per Share		Aggregate Intrinsic Value

The total intrinsic value of options exercised during the years ended December 31, 2014, 2013 and 2012 was $35.7 million, $2.2 million and $4.2 million, respectively.

The exercise prices of outstanding options at December 31, 2014 were in the following ranges:


	Options Outstanding						Options Exercisable
Range of Exercise Prices	Shares (in thousands)		Weighted Average Remaining Contractual Life (in years)		Weighted Average Exercise Price Per Share		Shares (in thousands)		Weighted Average Exercise Price Per Share

$2.96 to $25.36		10,411		6.1		7.32		6,826		6.30

The weighted average remaining contractual life of exercisable options at December 31, 2014 was 5.7 years.

The Company uses the Black-Scholes model to estimate the fair value of stock option awards at the date of grant. Key input assumptions used in the model include the grant date fair value of common stock, exercise price of the award, the expected option term, stock price volatility, estimated marketability discount (used in periods prior to the Company’s initial public offering), the risk-free interest rate and the Company’s projected dividend yield. The risk-free interest rates reflect the yield on zero-coupon U.S. treasury securities with a term equal to the option’s expected term. The expected life represents the period over which the Company’s employees are expected to hold their options. Expected volatility is derived based on the historical Company volatility, as well as volatilities from publicly traded companies operating in the Company’s industry. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in estimating the fair values of its stock options. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards. Subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company.

The following table presents the weighted average assumptions used to estimate the fair value of stock option awards granted:


	Year Ended December 31,
	2014			2013			2012
Expected option term (in years)		5.0			3.0			4.0
Risk-free interest rate		1.5	%		0.4	%		0.7	%
Expected volatility		45.0	%		75.0	%		75.0	%
Estimated marketability discount		—	%		15.0	%		30.0	%
Expected dividend yield		—	%		—	%		—	%
Weighted average fair value at grant date	$	9.41		$	4.69		$	3.24

Restricted Stock Units

RSUs entitle the holder to shares of common stock generally after a three-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 (in thousands, except per share data):


	Restricted Stock Units			Weighted Average Grant Date Fair Value Per Share
Outstanding and non-vested as of December 31, 2013		5		$	14.99
Granted		391			22.99
Vested and shares issued		(5	)		14.99
Forfeited		(19	)		23.05

Outstanding and non-vested as of December 31, 2014		372			22.99

Other

Share unit award expense of $4.5 million, $5.5 million and $3.5 million for the years ended December 31, 2014, 2013 and 2012, respectively, is included in equity-based compensation as an adjustment to reconcile net income to net cash generated by operating activities on the Consolidated Statements of Cash Flows.

The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically-identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material.

The following table summarizes the activity in the product warranty accrual, included in other accrued liabilities:

Segment Information

The Company’s three reportable segments, which align with the manner in which the business is managed, are Wireless, Enterprise and Broadband.

The Wireless segment provides merchant radio frequency (RF) wireless network connectivity solutions and small cell distributed antenna systems (DAS) solutions. These solutions, marketed primarily under the Andrew brand, enable wireless operators to deploy both cell sites and small cell DAS solutions to meet 2G, 3G and 4G cellular coverage and capacity requirements. Macro cell site solutions can be found at wireless tower sites and on rooftops and include base station, microwave antennas, hybrid fiber-feeder cables, coaxial cables, connectors, amplifiers, filters and backup power. Metro cell solutions can be found outdoors on street poles and on other urban structures and include RF delivery, equipment housing and concealment. These fully integrated outdoor systems consist of specialized antennas, filters/combiners, backhaul solutions, intra-system cabling and power distribution, all minimized to fit an urban environment. The small cell DAS solutions are composed of distributed antenna systems that allow wireless operators to extend and enhance cellular coverage and capacity in challenging network conditions such as commercial buildings, urban areas, stadiums and transportation systems.

The Enterprise segment provides connectivity and network intelligence for data centers and commercial buildings. These solutions include optical fiber and twisted pair structured cabling applications, intelligent infrastructure software, network rack and cabinet enclosures, intelligent building sensors, advanced LED lighting control systems and network design services.

The Broadband segment consists of cable and communications equipment that support the multi-channel video, voice and high-speed data services provided by cable operators. The segment’s products include coaxial and fiber-optic cables, fiber-to-the-home equipment, amplifiers, splitters, conduit and headend solutions for the network core.
