Accounting Policies [Abstract]

Background and Basis of Presentation

1. BACKGROUND AND BASIS OF PRESENTATION

Background

CommScope Holding Company, Inc., along with its direct and indirect subsidiaries (CommScope or the Company), is a global provider of essential infrastructure solutions for wireless, business enterprise and residential broadband networks. The Company’s solutions and services for wired and wireless networks enable high-bandwidth data, video and voice applications. CommScope’s global position is built upon innovative technology, broad solution offerings, high-quality and cost-effective customer solutions and global manufacturing and distribution scale.

Basis of Presentation

The Condensed Consolidated Balance Sheet as of March 31, 2014, the Condensed Consolidated Statements of Operations and Comprehensive Income, Cash Flows and Stockholders’ Equity for the three months ended March 31, 2014 and 2013 are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year.

The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and are presented in accordance with the applicable requirements of Regulation S-X. Accordingly, these financial statements do not include all of the information and notes required by U.S. GAAP for complete financial statements. The significant accounting policies followed by the Company are set forth in Note 2 within the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 (the 2013 Annual Report). There were no changes in the Company’s significant accounting policies during the three months ended March 31, 2014. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the audited consolidated financial statements. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements.

As of January 1, 2014, the Company adopted new accounting guidance that requires an entity to net its liability for uncertain tax positions as a reduction to deferred tax balances related to net operating loss carryforwards, similar tax losses or tax credit carryforwards when settlement in this manner is available under the tax law. The provisions of this new guidance did not have a material impact on the Company’s financial statements.

On October 4, 2013, the Company effected a 3-for-1 stock split of its common stock. All share and per share numbers have been revised to reflect the stock split.

Concentrations of Risk and Related Party Transactions

Net sales to Anixter International Inc. and its affiliates (Anixter) accounted for approximately 11% and 12% of the Company’s total net sales during the three months ended March 31, 2014 and 2013, respectively. Sales to Anixter primarily originate within the Enterprise segment. Other than Anixter, no customer accounted for 10% or more of the Company’s total net sales for the three months ended March 31, 2014 or 2013.

Accounts receivable from Anixter represented approximately 12% of accounts receivable as of March 31, 2014. Other than Anixter, no other customer accounted for 10% or more of the Company’s accounts receivable as of March 31, 2014.

As of March 31, 2014, the Company was 65.2% owned by funds affiliated with The Carlyle Group (Carlyle). The Company paid $0.8 million of the annual management and oversight fee to Carlyle in the three months ended March 31, 2013. In October 2013, the Company paid Carlyle approximately $20.2 million to terminate the management agreement.

Product Warranties

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

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


	Three Months Ended March 31,
	2014			2013
Product warranty accrual, beginning of period	$	24,838		$	26,005
Provision for warranty claims		2,269			960
Warranty claims paid		(4,169	)		(1,640	)

Product warranty accrual, end of period	$	22,938		$	25,325

Commitments and Contingencies

The Company is either a plaintiff or a defendant in pending legal matters in the normal course of business. Management believes none of these legal matters will have a material adverse effect on the Company’s business or financial condition upon final disposition.

As of March 31, 2014, the Company had commitments of $20.8 million to purchase metals that are expected to be consumed in normal production by September 2014. In the aggregate, these commitments were at prices approximately 8% above market prices as of March 31, 2014.

Asset Impairment

Property, plant and equipment 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 their estimated fair value. There were no impairments identified during the three months ended March 31, 2014. During the three months ended March 31, 2013, the Company obtained new market data regarding a facility which is being marketed for sale. Based on this data, the Company recorded a pretax asset impairment charge of $3.6 million which was recognized within the Wireless segment. Also during the three months ended March 31, 2013, the Company concluded that certain production equipment would no longer be utilized and consequently recorded pretax asset impairment charges of $2.0 million within the Wireless segment.

Income Taxes

The effective income tax rate of 36.9% for the three months ended March 31, 2014 was higher than the statutory rate of 35% primarily due to losses in certain jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable, increases in valuation allowances on certain tax attributes, the provision for state income taxes and certain tax costs associated with repatriation of foreign earnings. These items were partially offset by benefits related to uncertain tax positions for which the statutes had lapsed and the $5.4 million pretax reduction in the estimated fair value of contingent consideration payable, which is not subject to tax.

The effective income tax rate of 40.9% for the three months ended March 31, 2013 was higher than the statutory rate and did not reflect benefits for losses in certain foreign jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable. The effective tax rate for the first quarter of 2013 included a benefit for 2012 research and development tax credits as a result of legislation enacted early in 2013. This benefit was offset by additional expense related to uncertain tax positions and certain tax costs associated with repatriation of foreign earnings. Excluding these items, the effective tax rate was comparable to the statutory rate of 35%.

Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on net income divided by the weighted average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding equity-based awards such as stock options and restricted stock units. Certain outstanding equity-based awards were not included in the computation of diluted earnings per share because they would not have had a dilutive effect (0.4 million shares and 0.7 million shares for the three months ended March 31, 2014 and 2013, respectively). The following table presents the basis for the earnings per share computations:


	Three Months Ended March 31,
	2014		2013
Numerator:
Net income for basic and diluted earnings per share	$	64,487	$	15,900

Denominator:

Dilutive effect of equity-based awards		4,980		1,763

Business Combinations [Abstract]

Acquisitions

2. ACQUISITIONS

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 and is reported within the Enterprise segment. iTRACS’ sales during the three months ended March 31, 2014 were not material. The allocation of the purchase price, based on the estimated fair values of assets acquired and liabilities assumed, is as follows (in millions):


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 the company’s reputation in the marketplace and assembled workforce and is expected to be deductible for tax purposes.

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 three months ended March 31, 2014, the estimated fair value of the contingent consideration was reduced to $7.7 million (see Note 7). 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. Net sales of Redwood products and services were immaterial for the three months ended March 31, 2014 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 (in millions):


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 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 the fair value of certain tangible and intangible assets acquired and as additional information is obtained, adjustments may be made to the preliminary purchase price allocation.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Senior Secured Credit Facilities

During the three months ended March 31, 2014, the Company repaid $2.2 million of its senior secured term loans. No portion of the senior secured term loans was reflected as a current portion of long-term debt as of March 31, 2014 related to the potentially required excess cash flow payment because the amount that may be payable in 2015, if any, cannot currently be reliably estimated. There was no excess cash flow payment required in 2014 related to 2013.

During the three months ended March 31, 2014, the Company borrowed $15.0 million and repaid $15.0 million under the revolving credit facility. As of March 31, 2014, the Company had availability of approximately $345.0 million under the asset-based revolving credit facility, after giving effect to outstanding letters of credit.

Other Matters

The Company’s non-guarantor subsidiaries held approximately $1,061 million, or 22%, of total assets and approximately $312 million, or 9%, of total liabilities as of March 31, 2014 and accounted for approximately $320 million, or 34% of net sales for the three months ended March 31, 2014. As of December 31, 2013, the non-guarantor subsidiaries held approximately $1,077 million, or 23%, of total assets and approximately $315 million, or 9%, of total liabilities. For the three months ended March 31, 2013, the non-guarantor subsidiaries accounted for approximately $290 million, or 36%, of net sales. All amounts presented exclude intercompany balances.

The weighted average effective interest rate on outstanding borrowings, including the amortization of deferred financing costs and original issue discount, was 6.73% and 6.89% at March 31, 2014 and December 31, 2013, respectively.

Derivatives and Hedging Activities

6. 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 in order to mitigate the impact of changes in exchange rates. At March 31, 2014, the Company had foreign exchange contracts with maturities ranging from one to six months with an aggregate notional value of $309 million (based on exchange rates as of March 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 of Asset (Liability)
	Balance Sheet Location	March 31, 2014			December 31, 2013
Foreign currency contracts	Prepaid expenses and other current assets	$	2,055		$	2,738
Foreign currency contracts	Other accrued liabilities		(2,399	)		(662	)

Total derivatives not designated as hedging instruments		$	(344	)	$	2,076

The pretax impact of the foreign currency forward contracts not designated as hedging instruments on the Condensed Consolidated Statements of Operations and Comprehensive Income is as follows:


Foreign Currency Forward Contracts	Location of Gain (Loss)	Gain (Loss) Recognized
Three Months Ended March 31, 2014	Other expense, net	$	(3,032	)

Fair Value Disclosures [Abstract]

Fair Value Measurements

7. 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, 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 March 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 equity method investment 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 equity method investment, foreign currency contracts, senior notes, senior secured term loans, senior PIK toggle notes and contingent consideration payable as of March 31, 2014 and December 31, 2013, are as follows:


	March 31, 2014				December 31, 2013
	Carrying Amount		Fair Value		Carrying Amount		Fair Value		Valuation Inputs
Assets:
Equity method investment	$	2,541	$	59,593	$	3,112	$	41,879	Level 1
Foreign currency contracts		2,055		2,055		2,738		2,738	Level 2
Liabilities:
8.25% senior notes		1,100,000		1,190,750		1,100,000		1,205,280	Level 2
Senior secured term loans, at par		870,625		871,713		872,813		874,994	Level 2
Senior PIK toggle notes		550,000		581,625		550,000		572,000	Level 2
Foreign currency contracts		2,399		2,399		662		662	Level 2
Contingent consideration		7,718		7,718		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 three months ended March 31, 2014, the estimated fair value of the contingent consideration was reduced to $7.7 million based on the latest projections of Redwood’s performance, which resulted in a $5.4 million reduction in selling, general and administrative expense in the Condensed Consolidated Statement of Operations and Comprehensive Income.

These fair value estimates are based on pertinent information available to management as of March 31, 2014 and December 31, 2013. 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.

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’s infrastructure solutions enable wireless carriers to deploy macro cell sites and small cell solutions to meet coverage and capacity requirements driven by increasing demand for mobile bandwidth. The macro cell site solutions can be found at wireless tower sites and include base station and microwave antennas, hybrid fiber-feeder and power cables, coaxial cables, connectors, power amplifiers and environmentally-secure cabinets for equipment, including fuel cell backup power. The small cell solutions are primarily composed of distributed antenna systems that extend and enhance cellular coverage and capacity in challenging network conditions such as stadiums, transportation systems and commercial buildings.

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 and taps, conduit and headend solutions for the network core.

Restructuring And Related Activities [Abstract]

Restructuring Costs

9. RESTRUCTURING COSTS

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 and Statesville, North Carolina facilities. Much of the production capacity from these facilities is being shifted to other existing facilities or contract manufacturers. The Company’s net pretax restructuring charges, by segment, were as follows:


	Three Months Ended March 31,
	2014		2013
Wireless	$	1,238	$	1,120
Enterprise		214		453
Broadband		528		230

Total	$	1,980	$	1,803

The activity within the liability established for these restructuring actions, which is included in other accrued liabilities, was as follows:


	Employee- Related Costs			Lease Termination Costs			Fixed Asset Related Costs			Total
Balance as of December 31, 2013	$	17,173		$	1,399		$	—		$	18,572
Additional charge recorded		455			—			1,525			1,980
Cash paid		(4,918	)		(397	)		(1,525	)		(6,840	)
Foreign exchange and other non-cash items		13			1			—			14

Balance as of March 31, 2014	$	12,723		$	1,003		$	—		$	13,726

Employee-related costs include the expected severance costs and related benefits as well as any 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 vacating leased facilities, net of anticipated sub-rental income.

Fixed asset related costs include 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.

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 in 2011, the Company has recognized restructuring charges of $65.8 million. The additional pretax costs related to completing restructuring actions initiated to date are expected to be approximately $2.0 million to $3.0 million. Cash payments of approximately $14.0 million to $15.0 million are expected during the remainder of 2014 with an additional $1.0 million to $2.0 million expected to be paid by the end of 2015. In addition to the charges described above, the Company expects to recognize a restructuring charge in the second half of 2014 related to the lease agreement at its Joliet, Illinois facility once operations cease at that facility and that charge may be material. However, the Company cannot currently estimate the charge. Additional restructuring actions may be taken and the resulting charges and cash requirements could be material.

Stockholders' Equity

11. STOCKHOLDERS’ EQUITY

Equity-Based Compensation Plans

As of March 31, 2014, $28.0 million of total unrecognized compensation costs related to non-vested stock options, restricted stock unit awards (RSUs) and share unit awards are expected to be recognized over a remaining weighted average period of 1.9 years. Although the share unit awards may be settled in stock at the Company’s discretion, they have historically been settled in cash and are accounted for as liability awards. In the first quarter of 2014, $4.7 million of share unit awards vested and were paid in cash. There were no significant capitalized equity-based compensation costs at March 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
Outstanding as of December 31, 2013		10,828		$	6.15
Granted		750		$	23.00	$	9.40

Expected to vest		3,526		$	9.07			$	55,061

The exercise prices of outstanding options at March 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 $23.00		11,268		6.6	$	7.26		7,669	$	6.30

The Company uses the Black-Scholes model to estimate the fair value of stock option awards. 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, 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 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.


	Three Months Ended March 31,
	2014			2013
Expected option term (in years)		5.0			3.8
Risk-free interest rate		1.5	%		0.4	%

Expected dividend yield		—	%		—	%
Weighted average exercise price	$	23.00		$	11.11
Weighted average fair value at grant date	$	9.40		$	4.09

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		366	$	22.96

Outstanding and non-vested as of March 31, 2014		371	$	22.85

Other

Share unit award expense of $1.1 million and $1.2 million for the three months ended March 31, 2014 and 2013, respectively, is included in equity-based compensation as an adjustment to reconcile net income to net cash used in operating activities on the Condensed Consolidated Statements of Cash Flows.

Asset Impairment

Asset Impairment

Property, plant and equipment 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 their estimated fair value. There were no impairments identified during the three months ended March 31, 2014. During the three months ended March 31, 2013, the Company obtained new market data regarding a facility which is being marketed for sale. Based on this data, the Company recorded a pretax impairment charge of $3.6 million which was recognized within the Wireless segment. Also during the three months ended March 31, 2013, the Company concluded that certain production equipment would no longer be utilized and consequently recorded pretax impairment charges of $2.0 million within the Wireless segment.
