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 September 30, 2013, the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and nine months ended September 30, 2013 and 2012, and the Condensed Consolidated Statements of Cash Flows and Stockholders’ Equity for the nine months ended September 30, 2013 and 2012 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 Rule 10-01 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 Form S-1 filed October 11, 2013. There were no changes in the Company’s significant accounting policies during the three and nine months ended September 30, 2013. 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.
	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 12% of the Company’s total net sales during both the three and nine months ended September 30, 2013. Net sales to Anixter accounted for approximately 12% and 13% of the Company’s total net sales during the three and nine months ended September 30, 2012, 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 or nine months ended September 30, 2013 or 2012.
	Accounts receivable from Anixter represented approximately 12% of accounts receivable as of September 30, 2013. Other than Anixter, no other customer accounted for 10% or more of the Company’s accounts receivable as of September 30, 2013.
	As of September 30, 2013, the Company was 98.4% 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 both the three months ended September 30, 2013 and 2012 and $2.3 million of the annual management and oversight fee to Carlyle in both the nine months ended September 30, 2013 and 2012. In October 2013, the Company paid Carlyle approximately $20.2 million to terminate the management agreement. See Footnote 12 – Subsequent Events.
	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						Nine Months Ended
			September 30,						September 30,
			2013			2012			2013			2012
	Product warranty accrual, beginning of period		$	24,127		$	19,923		$	26,005		$	18,653
	Provision for warranty claims			2,421			6,708			3,568			11,151
	Warranty claims paid			(2,437	)		(1,752	)		(5,462	)		(4,925	)
	Product warranty accrual, end of period		$	24,111		$	24,879		$	24,111		$	24,879
	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 other legal matters will have a material adverse effect on the Company’s business or financial condition upon final disposition.
	On May 12, 2010, a putative stockholder class action lawsuit, asserting claims under the Securities Exchange Act of 1934 (the 1934 Act), was filed in the United States District Court for the Western District of North Carolina against the Company and certain of its current and former officers. The lawsuit alleged violations of the 1934 Act and SEC Rule 10b-5, related to allegedly false and misleading statements and/or omissions by the Company about its financial condition and future sales prospects during the period between April 29, 2008 and October 30, 2008. On August 6, 2013, the United States District Court for the Western District of North Carolina granted the Company’s motion to dismiss the stockholder class action lawsuit and entered judgment in favor of the Company. Plaintiffs did not file a Notice of Appeal by the deadline and thus this lawsuit was concluded in the favor of CommScope and the other defendants.
	As of September 30, 2013, the Company had commitments of $17.1 million to purchase metals that are expected to be consumed in normal production by March 2014. In the aggregate, these commitments were at prices less than 2% above market prices as of September 30, 2013.
	Asset Impairment
	During the first six months of 2013, the Broadband segment experienced lower than expected levels of sales and operating income. Management considered these results and the longer term effect of market conditions on the continued operations of the business and determined that an indicator of possible impairment existed. A step one goodwill impairment test was performed using a discounted cash flow (DCF) valuation model. The significant assumptions in the DCF model are the annual revenue growth rate, the annual operating income margin, and the discount rate used to determine the present value of the cash flow projections. The discount rate was based on the estimated weighted average cost of capital as of the test date of market participants in the industry in which the Broadband segment (which is considered a reporting unit) operates. Based on the estimated fair values generated by the DCF model, the Broadband segment did not pass step one of the goodwill impairment test. Accordingly, a step two analysis was initiated, and a preliminary goodwill impairment charge of $28.8 million was recorded during the three months ended June 30, 2013. The step two analysis was completed during the three months ended September 30, 2013 and an incremental $7.3 million impairment charge was recorded. The goodwill impairment charge resulted primarily from lower projected operating results than those assumed during the 2012 annual impairment test.
	A summary of the effects of changes in key assumptions, assuming all other assumptions remain constant, on the fair value compared to the carrying value, as of the impairment test date is as follows:
			Deficit of estimated fair value compared to the
			carrying value as a percent of carrying value
	Reportable Segment		Actual			Decrease of 0.5% in			Decrease of 0.5% in			Increase of
			valuation			annual revenue			annual operating			0.5% in
						growth rate			income margin			discount rate
	Broadband			(1.3	)%		(5.0	)%		(6.1	)%		(4.7	)%
	The weighted average discount rate used in the impairment test for the Broadband segment was 11.0% compared to 11.5% that was used in the 2012 annual goodwill impairment test.
	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. During the nine months ended September 30, 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 nine months ended September 30, 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.
	Income Taxes
	For the three and nine months ended September 30, 2013, income tax expense reflected net increases in valuation allowances of $4.0 million and $25.2 million, respectively, related to (1) foreign tax credit carryforwards that the Company has determined are not likely to be realized, primarily due to an increase in future interest expense expected as a result of current year borrowings and (2) net operating loss carryforwards in certain foreign jurisdictions as a result of changes in profitability. In addition to the impact of the valuation allowances, the effective income tax rate for the three and nine months ended September 30, 2013 was also affected by goodwill impairment charges for which no tax benefit was recognized, 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.
	Income tax expense for the three and nine months ended September 30, 2012 reflected net increases in valuation allowances in foreign jurisdictions, adjustments related to filing the 2011 U.S. federal income tax return and additional expense related to uncertain tax positions. In addition to these items, the effective income tax rate for the prior year periods 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 and tax costs associated with repatriation of foreign earnings.
	Excluding the items listed above, the effective income tax rate for the three and nine months ended September 30, 2013 and 2012 was higher than the statutory rate of 35% primarily due to the provision for state income taxes and certain tax costs associated with repatriation of foreign earnings. The Company expects to continue to provide U.S. taxes on substantially all of our current year foreign earnings in anticipation that such earnings will be repatriated to the U.S.
	Earnings (Loss) Per Share
	Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is based on net income (loss) divided by the weighted average number of common shares outstanding adjusted for the dilutive effect of stock options. Below is a reconciliation of weighted average common shares and potential common shares outstanding for calculating diluted earnings (loss) per share:
			Three Months Ended						Nine Months Ended
			September 30,						September 30,
			2013			2012			2013			2012
	Numerator:
	Net income (loss) for basic and diluted earnings (loss) per share		$	11,287		$	5,284		$	28,309		$	(6,097	)
	Denominator:
	Weighted average number of common shares outstanding for basic earnings (loss) per share			154,885			154,706			154,883			154,701
	Effect of dilutive securities:
	Stock options (a)			4,179			671			3,125			—
	Weighted average number of common shares and potential common shares outstanding for diluted earnings (loss) per share			159,064			155,377			158,008			154,701
	(a)	No options to purchase common shares were excluded from the computation of diluted earnings per share for the three months ended September 30, 2013 and 7.5 million common shares were excluded from the computation of diluted loss per share for the three months ended September 30, 2012, because they would have been anti-dilutive. Options to purchase 0.2 million and 11.2 million common shares were excluded from the computation of diluted earnings (loss) per share for the nine months ended September 30, 2013 and 2012, respectively, because they would have been anti-dilutive.

Acquisitions	'
	2. ACQUISITIONS
	In March 2013, the Company acquired substantially all of the assets and assumed certain liabilities of iTRACS Corporation (iTRACS) for approximately $34.0 million in cash. iTRACS develops and markets enterprise-class data center infrastructure management (DCIM) solutions and is reported within the Enterprise segment. Net sales of iTRACS products and services were immaterial for the three and nine months ended September 30, 2013. The preliminary allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows:
		Estimated Fair Value
		(in millions)
	Current assets	$	1.6
	Noncurrent assets, excluding intangible assets		0.7
	Other intangible assets		13.1
	Goodwill		19.8
	Less: Liabilities assumed		(1.2	)
	Net acquisition cost	$	34
	The goodwill arising from the preliminary purchase price allocation of the iTRACS acquisition is believed to result from the company’s reputation in the marketplace and assembled workforce and is expected to be deductible for tax purposes.
	As additional information is obtained, adjustments may be made to the preliminary purchase price allocation. The Company is still finalizing the valuation of the fair value of certain tangible and intangible assets acquired.
	In July 2013, the Company acquired Redwood Systems, Inc. (Redwood), a provider of LED lighting solutions and integrated sensor networks for data centers and buildings. Redwood was acquired for an initial payment of $9.8 million and contingent consideration with an estimated fair value of $12.4 million. The Company may be required to pay up to an additional $37.25 million of consideration if certain net sales targets of up to $55.0 million are met over various periods through July 31, 2015. In addition there are retention payments for employees of Redwood of up to $11.75 million based on the same net sales targets as the contingent consideration. Net sales of Redwood products and services were $1.0 million for both the three and nine months ended September 30, 2013 and are reported in the Enterprise segment. The preliminary allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows:
		Estimated Fair Value
		(in millions)
	Current assets	$	2.4
	Deferred taxes		8.2
	Other intangible assets		9
	Goodwill		3.5
	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 and as additional information is obtained, adjustments may be made to the preliminary purchase price allocation.
	During the three months ended September 30, 2013, the Company paid the final purchase price payment ($12 million) for the Argus acquisition.

	Senior PIK Toggle Notes
	On May 28, 2013, CommScope Holding Company, Inc. (Holdco) 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 senior PIK toggle notes are senior unsecured obligations that are not guaranteed by any of Holdco’s subsidiaries.
	Holdco 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%.
	The senior PIK toggle notes will pay interest semi-annually in arrears on each June 1 and December 1, commencing on December 1, 2013. The first interest payment on the senior PIK toggle notes is payable in cash. For each interest period thereafter, Holdco 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, Holdco may elect to pay a portion of the interest due on the senior PIK toggle notes for such interest period by increasing the principal amount of the senior PIK toggle notes or by issuing new notes for up to the entire amount of the interest payment (in each case, PIK interest) to the extent described in the PIK Notes Indenture. Cash interest on the senior PIK toggle notes will accrue at the rate of 6.625% per annum. PIK interest on the senior PIK toggle notes will accrue at the rate of 7.375% per annum until the next payment of cash interest.
	For the purposes of the PIK Notes Indenture, “Applicable Amount” generally refers to the Company’s then current restricted payment capacity under the instruments governing the Company’s indebtedness, less $20 million, and plus Holdco’s cash and cash equivalents less $10 million. Based on the Applicable Amount, as of September 30, 2013, Holdco 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 subsidiaries of Holdco. 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. Holdco 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.
	The net proceeds from the issuance of the senior PIK toggle notes and available cash were used to fund a $550.0 million special cash dividend and distribution to Holdco’s equity holders.
	Senior Secured Credit Facilities
	During the first quarter of 2013, the Company amended its senior secured term loan primarily to lower the interest rate. The amendment resulted in the repayment of $32.0 million to certain lenders who exited the senior secured term loan syndicate and the receipt of $32.0 million in proceeds from new lenders and existing lenders who increased their positions. The senior secured term loan was amended such that the interest rate is now equal to, 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 term loan and revolving credit facility, and the one-month Eurodollar rate plus 1.0%) plus a margin of 1.75% or (2) the greater of (a) one-, two-, three- or six-month LIBOR (selected at the Company’s option) plus a margin of 2.75% or (b) 3.75%. The unused line fee calculated on the undrawn portion of the revolving credit facility was 0.375% as of September 30, 2013 based on usage of the facility.
	As a result of the lenders who exited the senior secured term loan syndicate in conjunction with the amendment, $0.2 million of original issue discount and $0.3 million of deferred financing fees associated with the senior secured term loan were written off and included in interest expense. In connection with amending the senior secured term loan, the Company incurred pretax costs of $1.9 million, which are included in other expense, net on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) and in long-term debt financing costs on the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2013.
	During the three and nine months ended September 30, 2013, the Company made scheduled principal repayments of $2.5 million and $7.5 million, respectively, on its senior secured term loan. None of the senior secured term loan was reflected as a current portion of long-term debt as of September 30, 2013 related to the excess cash flow payment that may be required because the amount that may be payable in 2014, if any, cannot currently be reliably estimated. There was no excess cash flow payment required in 2013 related to 2012.
	During the nine months ended September 30, 2013, the Company borrowed and repaid $165.0 million under the revolving credit facility. As of September 30, 2013, the Company had remaining availability of approximately $328.7 million under the asset-based revolving credit facility, after giving effect to $56.7 million of outstanding letters of credit and the borrowing base limitations for additional secured borrowings.
	Other Matters
	The Company’s non-guarantor subsidiaries under the 8.25% senior notes due January 2019 held approximately $1,067 million, or 22.2%, of total assets and approximately $271 million, or 6.6%, of total liabilities as of September 30, 2013 and accounted for approximately $338 million, or 38.1%, and $992 million, or 37.7%, of net sales for the three and nine months ended September 30, 2013, respectively. As of December 31, 2012, the non-guarantor subsidiaries held approximately $952 million, or 20%, of total assets and approximately $270 million, or 7%, of total liabilities. For the three and nine months ended September 30, 2012, the non-guarantor subsidiaries accounted for approximately $354 million, or 39.6%, and $1,017 million, or 41.1%, respectively, 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 7.09% and 7.33% at September 30, 2013 and December 31, 2012, respectively.
	See Note 6 in the audited consolidated financial statements included in the Company’s Form S-1 filed October 11, 2013 for additional information on the terms and conditions of the 8.25% senior notes and the senior secured credit facilities.

	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 September 30, 2013, the Company had foreign exchange contracts with maturities ranging from one to six months with an aggregate notional value of $212 million (based on exchange rates as of September 30, 2013). Unrealized gains and losses resulting from these contracts are recognized in other expense, net and partially offset corresponding foreign exchange gains and losses on these balances. These instruments are not held for speculative or trading purposes. These contracts are not designated as hedges for hedge accounting and are marked to market each period through earnings. The following table presents the balance sheet location and fair value of the Company’s derivatives:
			Fair Value of Asset (Liability)
		Balance Sheet Location	September 30, 2013			December 31, 2012
	Foreign currency contracts	Prepaid expenses and other current assets	$	2,887		$	1,314

	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 September 30, 2013 and December 31, 2012 were considered representative of their fair values due to their short terms to maturity. 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 PIK toggle notes, senior secured term loans and contingent consideration payable as of September 30, 2013 and December 31, 2012, are as follows:

	Contingent consideration	$	12,937	$	12,937	$	—	$	—		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. Expense of $0.6 million related to the change in estimated fair value was recorded in selling, general and administrative expense in the Condensed Consolidated Statement of Operations and Comprehensive Income (Loss) for the three and nine months ended September 30, 2013.
	During the three and nine months ended September 30, 2013, the Company recorded pretax goodwill impairment charges of $7.3 million and $36.2 million, respectively, related to the Broadband segment as a result of reduced expectations of future cash flows, primarily from lower projected operating results. The valuations supporting the goodwill impairment charges are based on Level 3 valuation inputs. During the nine months ended September 30, 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 nine months ended September 30, 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. The valuations supporting the facility and equipment impairment charges are based on Level 3 valuation inputs.
	These fair value estimates are based on pertinent information available to management as of September 30, 2013 and December 31, 2012. Although management is not aware of any factors that would significantly affect these fair value estimates, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates and current estimates of fair value may differ significantly from the amounts presented.

	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 as well as demolition costs for the Orland Park, Illinois former manufacturing facility. 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 begun in 2011, the Company has recognized restructuring charges of $58.1 million. The additional pretax costs related to completing restructuring actions initiated to date are not expected to be significant. Cash payments of approximately $2.0 million to $3.0 million are expected during the remainder of 2013 with an additional $5.0 million to $6.0 million expected to be paid by the end of 2015. Additional restructuring actions may be taken and the resulting charges and cash requirements could be material.

	Dividend
	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 with the May 28, 2013 dividend, 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 options that were granted following the Carlyle acquisition were adjusted to reflect the 2013 dividends. Cash payments of $7.2 million and $4.1 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 May and June dividend, 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
	As of September 30, 2013, $21.9 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 2.0 years. The share unit awards are payable in cash and are accounted for as liability awards. Following the initial public offering, the share unit awards may, at the Company’s discretion, be settled in stock. There were no significant capitalized equity-based compensation costs at September 30, 2013. The Company intends to settle the share unit awards that vest in January 2014 in cash.
	Stock Options
	During the nine months ended September 30, 2013, the Board of Directors modified the 2012 performance targets for certain stock options. As a result of this change, the Company determined a new fair value as of the modification date and recognized expense of $2.4 million. The following table summarizes the stock option activity (in thousands, except per share amounts):
			Shares			Weighted			Weighted
						Average Option			Average Grant
						Exercise Price			Date Fair Value

	Outstanding as of June 30, 2013			11,319		$	6.13

	-1	The weighted-average exercise prices at June 30, 2013 and September 30, 2013 reflect the adjustment of $2.48 per share resulting from the 2013 dividends that was made with respect to options granted after the Carlyle acquisition, as described above.
	The exercise prices of outstanding options at September 30, 2013 were in the following ranges:
			Options Outstanding								Options Exercisable
	Range of Exercise Prices		Shares			Weighted			Weighted		Shares		Weighted
			(in thousands)			Average			Average		(in thousands)		Average

	$2.96 to $8.90			11,037			6.9		$	6.14		6,132	$	6.13
	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 or modified.

Subsequent Events	'
	12. SUBSEQUENT EVENTS
	On October 4, 2013, the Company’s Board of Directors approved a 3-for-1 stock split of the Company’s outstanding common stock and an increase in authorized capital stock to 1,300,000,000 shares of common stock and 200,000,000 shares of preferred stock, which were effective as of October 4, 2013. The number of shares of common stock into which each outstanding option to purchase common stock is exercisable was proportionally increased and the exercise price of each outstanding option to purchase common stock was proportionally decreased. All of the share numbers, share prices, and exercise prices and other per share information throughout these financial statements have been adjusted on a retroactive basis, to reflect this 3-for-1 split, including revising common stock and additional paid-in capital to reflect the additional outstanding shares ($0.01 par value per share) resulting from the split.
	In October 2013, the Company completed an initial public offering (IPO) of its common stock. The Company issued 30.8 million shares of common stock and the funds affiliated with Carlyle (Carlyle funds) sold 7.7 million shares, reducing the Carlyle funds’ ownership to approximately 77.9%. The underwriters have an option to purchase an additional 5.8 million shares from the Carlyle funds within 30 days of the IPO. If fully exercised, this would reduce the Carlyle funds’ ownership to approximately 74.8%. The Company raised $433 million, net of transaction costs, from the IPO.
	Subsequent to the IPO, the Company issued redemption notices for $400.0 million of its 8.25% senior notes. The Company expects to pay a redemption price of 108.25% plus accrued and unpaid interest to the redemption date (November 25, 2013).
	In October 2013, the Company paid Carlyle a fee of approximately $20.2 million to terminate the management agreement.
	Also in October 2013, the Company filed a registration statement on Form S-8 to register 31.6 million shares of its common stock for issuance under our equity incentive plans.
	Following the IPO, Moody’s Investors Service upgraded CommScope Holding Company, Inc.’s corporate family rating to B1 from B2 with a stable outlook and Standard & Poor’s Ratings Services raised its corporate credit ratings on CommScope Holding Company Inc. and CommScope Inc. to BB- from B+, with a stable outlook.
	On November 6, 2013, the Company announced that in order to improve manufacturing facility utilization, it would be closing the Joliet, Illinois manufacturing operation and shifting the production to existing facilities in North Carolina and to third party suppliers. This action is expected to be substantially completed by the second quarter of 2014 and will impact approximately 200 employees in Joliet and result in non-cash asset impairment charges of up to $10 million and restructuring charges that will require cash of approximately $15 million.
