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 June 30, 2014, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and six months ended June 30, 2014 and 2013, and the Condensed Consolidated Statements of Cash Flows and Stockholders’ Equity for the six months ended June 30, 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 and six months ended June 30, 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% of the Company’s total net sales during the three and six months ended June 30, 2014. Net sales to Anixter accounted for approximately 12% of the Company’s total net sales during the three and six months ended June 30, 2013. Sales to Anixter primarily originate within the Enterprise segment. Other than Anixter, no direct customer accounted for 10% or more of the Company’s total net sales for the three or six months ended June 30, 2014 or 2013.
	Accounts receivable from Anixter represented approximately 12% of accounts receivable as of June 30, 2014. Other than Anixter, no direct customer accounted for 10% or more of the Company’s accounts receivable as of June 30, 2014.
	As of June 30, 2014, the Company was 54% owned by funds affiliated with The Carlyle Group (Carlyle). The Company paid $0.8 million and $1.5 million of management and oversight fees to Carlyle in the three and six months ended June 30, 2013, respectively. 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						Six Months Ended
		June 30,						June 30,
		2014			2013			2014			2013
	Product warranty accrual, beginning of period	$	22,938		$	25,325		$	24,838		$	26,005
	Provision for warranty claims		2,662			187			4,931			1,147
	Warranty claims paid		(3,805	)		(1,385	)		(7,974	)		(3,025	)
	Product warranty accrual, end of period	$	21,795		$	24,127		$	21,795		$	24,127
	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 June 30, 2014, the Company had commitments of $23.6 million to purchase metals that are expected to be consumed in normal production by the fourth quarter of 2014. In the aggregate, these commitments were at prices approximately 1% above market prices as of June 30, 2014.
	Asset Impairments
	Property, plant and equipment and intangible assets 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. During the three months ended June 30, 2014, as a result of revisions to the business plan for a particular product line, the Company determined that certain intangible assets in the Broadband segment were no longer recoverable and a $7.2 million impairment charge was recorded. During the three months ended June 30, 2013, a goodwill impairment charge of $28.8 million was recorded in the Broadband segment primarily as a result of lower projected operating results than those used in the 2012 annual impairment test. During the six months ended June 30, 2013, the Company also recorded pretax impairment charges in the Wireless segment of $5.6 million related to certain real estate and production equipment.
	Income Taxes
	The effective income tax rate of 46.4% and 40.1% for the three and six months ended June 30, 2014, respectively, was higher than the statutory rate of 35% primarily due to increases in valuation allowances for foreign tax credit carryforwards, losses in certain jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable, the provision for state income taxes and certain tax costs associated with repatriation of foreign earnings. In addition, no tax benefit was recognized on the $7.2 million asset impairment charge recorded during the second quarter of 2014. These items were partially offset by gains of $6.6 million and $12.0 million in the three and six months ended June 30, 2014, respectively, that resulted from the reduction in the estimated fair value of contingent consideration payable, which is not subject to tax. The Company also recognized a reduction in tax expense during the six months ended June 30, 2014 related to uncertain tax positions for which the statutes of limitations had lapsed.
	The effective income tax rate for the three and six months ended June 30, 2013 was higher than the statutory rate of 35% primarily due to the establishment of a valuation allowance of $29.5 million related to foreign tax credit carryforwards that was partially offset by the reversal of a previously established valuation allowance of $8.3 million related to net operating loss carryforwards in a foreign jurisdiction as a result of improved profitability. In addition, no tax benefit was recognized on the $28.8 million goodwill impairment charge recorded during the second quarter of 2013. The effective tax rate for the three and six months ended June 30, 2013 was also impacted by losses in certain foreign jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable, tax costs associated with repatriation of foreign earnings and adjustments related to prior years’ tax returns in various jurisdictions.
	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 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 the effect was either antidilutive or the performance condition was not met (2.2 million shares and 1.9 million shares for the three and six months ended June 30, 2014, respectively, and 2.5 million shares and 2.4 million shares for the three and six months ended June 30, 2013, respectively). The following table presents the basis for the earnings per share computations:
		Three Months Ended						Six Months Ended

	Weighted average common shares outstanding - diluted		190,984			158,316			190,694			157,480
	Recent Accounting Pronouncements
	On May 28, 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	'
	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. Net sales of iTRACS products and services were immaterial for the three and six months ended June 30, 2014 and are reported in 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):
	Current assets	$	1.7
	Noncurrent assets, excluding intangible assets		0.7
	Identifiable 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 six months ended June 30, 2014, the estimated fair value of the liability for contingent consideration was reduced to $1.1 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 $2.4 million and $4.2 million, respectively, for the three and six months ended June 30, 2014 and are reported in the Enterprise segment. The Company does not believe that it is probable that any of the retention payments will be made. The 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
	Identifiable intangible assets		9
	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 tax purposes.

	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. The Company owns 1.69 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 three months ended June 30, 2014, the Company reduced its ownership in Hydrogenics from 24.1% to 16.7%. As a result, the Company no longer is considered to have significant influence over the investee’s operating and financial policies and changed its method of accounting from the equity method to classifying the investment as available-for-sale.
	As of June 30, 2014 the cost basis of the investment in Hydrogenics was $1.3 million, the fair value was $31.5 million and the unrealized pretax gains recorded in accumulated other comprehensive income were $30.2 million. 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 Condensed Consolidated Balance Sheets.
	During the three months ended June 30, 2014, the company sold 0.5 million shares of Hydrogenics common stock and received proceeds of $7.1 million (included in other investing activities on the Condensed Consolidated Statements of Cash Flows) and recorded a pretax realized gain of $6.7 million (recorded in other expense, net on the Condensed Consolidated Statements of Operations and Comprehensive Income). No amounts were reclassified from accumulated other comprehensive income during the three and six months ended June 30, 2014.
	The Company’s share of earnings and losses as well as any impairment of its equity method investments are recorded in other expense, net on the Condensed Consolidated Statements of Operations and Comprehensive Income. The Company’s share of losses in its equity method investments was $0.9 million and $1.5 million for the three and six months ended June 30, 2014, respectively, compared to income of $0.8 million and losses of $0.1 million for the three and six months ended June 30, 2013, respectively. For the six months ended June 30, 2013, the Company also recorded an impairment charge of $0.8 million related to one of its equity method investments.

	5.00% Senior Notes Due 2021 and 5.50% Senior Notes Due 2024
	In May 2014, CommScope, Inc. 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, beginning December 15, 2014.
	Proceeds from the New Notes were used to redeem the entire outstanding amount of 2019 Notes plus pay a redemption premium of $93.9 million, which was included in other expense, net. The remainder of the net proceeds were 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.
	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 $23.5 million during the three and six months ended June 30, 2014, which were capitalized as other noncurrent assets and are being amortized over the terms of the notes.
	Senior Secured Credit Facilities
	During the three and six months ended June 30, 2014, the Company repaid $2.2 million and $4.4 million, respectively, 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 June 30, 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 six months ended June 30, 2014, the Company borrowed and repaid $15.0 million under the revolving credit facility. As of June 30, 2014, the Company had availability of approximately $352.8 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 $1,219 million, or 24%, of total assets and approximately $356 million, or 9%, of total liabilities as of June 30, 2014 and accounted for approximately $382 million, or 36%, and $702 million, or 35%, of net sales for the three and six months ended June 30, 2014, respectively. 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 and six months ended June 30, 2013, the non-guarantor subsidiaries accounted for approximately $364 million, or 39%, and $654, or 38%, of net sales, respectively. All amounts presented exclude intercompany balances.
	CommScope, Inc., a subsidiary of the Company, is the issuer of the 2021 and 2024 Notes. The reported balances for CommScope, Inc. are substantially identical to those of the Company other than interest expense for CommScope, Inc. for the three and six months ended June 30, 2014 does not reflect the interest expense incurred in connection with the senior PIK toggle notes, which was $9.5 million and $19.0 million, respectively, during such periods ($6.1 million and $12.1 million net of tax, respectively). Total debt for CommScope, Inc. as of June 30, 2014 was $2,161.1 million, which does not include the senior PIK toggle notes.
	The weighted average effective interest rate on outstanding borrowings, including the amortization of deferred financing costs and original issue discount, was 5.36% and 6.89% at June 30, 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 and to manage exposure to certain planned foreign currency expenditures in order to mitigate the impact of changes in exchange rates. At June 30, 2014, the Company had foreign exchange contracts with maturities ranging from one to five months with an aggregate notional value of $308 million (based on exchange rates as of June 30, 2014). Unrealized gains and losses resulting from these contracts are recognized in other expense, net and partially offset corresponding foreign exchange transaction gains and losses and the impact of foreign exchange rate fluctuations on various operating expenses. 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	June 30, 2014			December 31, 2013
	Foreign currency contracts	Prepaid expenses and other current assets	$	1,678		$	2,738
	Foreign currency contracts	Other accrued liabilities		(1,466	)		(662	)

	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, 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 June 30, 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 June 30, 2014 and December 31, 2013, are as follows:

	Contingent consideration		1,076		1,076		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 six months ended June 30, 2014, the estimated fair value of the contingent consideration was reduced to $1.1 million based on the latest projections of Redwood’s performance, which resulted in a $12.0 million reduction in selling, general and administrative expense in the Condensed Consolidated Statements of Operations and Comprehensive Income.
	During the three months ended June 30, 2014, the company recorded an impairment charge of $7.2 to reduce certain intangible assets in the Broadband segment to their estimated fair value. The valuations supporting the impairment charge were based on Level 3 valuation inputs.
	These fair value estimates are based on pertinent information available to management as of June 30, 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 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:

	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 non-cash impairment or disposals of fixed assets associated with restructuring actions in addition to the 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.
	The Company has recognized restructuring charges of $68.1 million since 2011. The additional pretax costs related to completing restructuring actions initiated to date are expected to be approximately $1.0 million to $2.0 million. Cash payments of approximately $9.0 million to $10.0 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 that expires in 2022. The charge is expected to be $7.0 million to $10.0 million for the portion of the facility the Company will attempt to sublease once operations cease at that facility. Additional restructuring actions may be taken and the resulting charges and cash requirements could be material.

	Dividends
	On May 28, 2013, the Company’s Board of Directors declared a dividend of $2.21 per share of its common stock. The dividend paid on May 28, 2013 was $342.8 million. On June 28, 2013, the Company’s Board of Directors declared a dividend of $1.26 per share of its common stock, collectively, the 2013 dividends. The dividend paid on June 28, 2013 was $195.9 million.
	In accordance with the antidilution provisions of the Company’s stock incentive plans, the exercise prices of certain options outstanding were adjusted to reflect the 2013 dividends. A cash payment of $7.2 million was made to stock option holders of options granted prior to 2011 in lieu of a reduction in exercise prices on the May dividend and a payable of $4.1 million was recorded related to the June dividend and was paid in July 2013. 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
	As of June 30, 2014, $25.9 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 1.6 years. Although the share unit awards may at the Company’s discretion be settled in stock, they have historically been settled in cash and are accounted for as liability awards. There were no significant capitalized equity-based compensation costs at June 30, 2014.

	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.

	Basis of Presentation
	The Condensed Consolidated Balance Sheet as of June 30, 2014, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and six months ended June 30, 2014 and 2013, and the Condensed Consolidated Statements of Cash Flows and Stockholders’ Equity for the six months ended June 30, 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 and six months ended June 30, 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	'
	Concentrations of Risk and Related Party Transactions
	Net sales to Anixter International Inc. and its affiliates (Anixter) accounted for approximately 11% of the Company’s total net sales during the three and six months ended June 30, 2014. Net sales to Anixter accounted for approximately 12% of the Company’s total net sales during the three and six months ended June 30, 2013. Sales to Anixter primarily originate within the Enterprise segment. Other than Anixter, no direct customer accounted for 10% or more of the Company’s total net sales for the three or six months ended June 30, 2014 or 2013.
	Accounts receivable from Anixter represented approximately 12% of accounts receivable as of June 30, 2014. Other than Anixter, no direct customer accounted for 10% or more of the Company’s accounts receivable as of June 30, 2014.
	As of June 30, 2014, the Company was 54% owned by funds affiliated with The Carlyle Group (Carlyle). The Company paid $0.8 million and $1.5 million of management and oversight fees to Carlyle in the three and six months ended June 30, 2013, respectively. In October 2013, the Company paid Carlyle approximately $20.2 million to terminate the management agreement.
Product Warranties	'
	Product Warranties
	The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically-identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material.
	The following table summarizes the activity in the product warranty accrual, included in other accrued liabilities:

	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 June 30, 2014, the Company had commitments of $23.6 million to purchase metals that are expected to be consumed in normal production by the fourth quarter of 2014. In the aggregate, these commitments were at prices approximately 1% above market prices as of June 30, 2014.
Asset Impairments	'
	Asset Impairments
	Property, plant and equipment and intangible assets 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. During the three months ended June 30, 2014, as a result of revisions to the business plan for a particular product line, the Company determined that certain intangible assets in the Broadband segment were no longer recoverable and a $7.2 million impairment charge was recorded. During the three months ended June 30, 2013, a goodwill impairment charge of $28.8 million was recorded in the Broadband segment primarily as a result of lower projected operating results than those used in the 2012 annual impairment test. During the six months ended June 30, 2013, the Company recorded pretax impairment charges in the Wireless segment of $5.6 million related to certain real estate and production equipment.
Income Taxes	'
	Income Taxes
	The effective income tax rate of 46.4% and 40.1% for the three and six months ended June 30, 2014, respectively, was higher than the statutory rate of 35% primarily due to increases in valuation allowances for foreign tax credit carryforwards, losses in certain jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable, the provision for state income taxes and certain tax costs associated with repatriation of foreign earnings. In addition, no tax benefit was recognized on the $7.2 million asset impairment charge recorded during the second quarter of 2014. These items were partially offset by gains of $6.6 million and $12.0 million in the three and six months ended June 30, 2014, respectively, that resulted from the reduction in the estimated fair value of contingent consideration payable, which is not subject to tax. The Company also recognized a reduction in tax expense during the six months ended June 30, 2014 related to uncertain tax positions for which the statutes of limitations had lapsed.
	The effective income tax rate for the three and six months ended June 30, 2013 was higher than the statutory rate of 35% primarily due to the establishment of a valuation allowance of $29.5 million related to foreign tax credit carryforwards that was partially offset by the reversal of a previously established valuation allowance of $8.3 million related to net operating loss carryforwards in a foreign jurisdiction as a result of improved profitability. In addition, no tax benefit was recognized on the $28.8 million goodwill impairment charge recorded during the second quarter of 2013. The effective tax rate for the three and six months ended June 30, 2013 was also impacted by losses in certain foreign jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable, tax costs associated with repatriation of foreign earnings and adjustments related to prior years’ tax returns in various jurisdictions.
Earnings Per Share	'
	Earnings Per Share
	Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on net income divided by the weighted average number of common shares outstanding plus the dilutive effect of potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding equity-based awards 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 the effect was either antidilutive or the performance condition was not met (2.2 million shares and 1.9 million shares for the three and six months ended June 30, 2014, respectively, and 2.5 million shares and 2.4 million shares for the three and six months ended June 30, 2013, respectively).

	On May 28, 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.
