	Nortek, Inc. (“Nortek”) and all of its wholly owned subsidiaries (collectively the “Company”) is a global, diversified company whose many market-leading brands deliver broad capabilities and a wide array of innovative, technology-driven products and solutions for lifestyle improvement at home and at work. Operating within five reporting segments (see Note J, “Segment Information”), the Company manufactures and sells, primarily in the United States, Canada and Europe, with additional manufacturing in China, a wide variety of products for the remodeling and replacement markets, the residential and commercial new construction markets, the manufactured housing market, and the personal and enterprise computer markets.
	The Company operates on a calendar year, and each interim period is comprised of two 4-week periods and one 5-week period, with each week ending on a Saturday. The Company's fiscal year always begins on January 1 and ends on December 31. As a result, the Company's first and fourth quarters may have more or less days included than a traditional 4-4-5 fiscal calendar, which consists of 91 days. The three months ended September 28, 2013 (“third quarter of 2013”) and September 29, 2012 (“third quarter of 2012”) each include 91 days. The first nine months ended September 28, 2013 ("nine months of 2013") and September 29, 2012 ("nine months of 2012") include 271 days and 273 days, respectively.
	The accompanying unaudited condensed consolidated financial statements reflect the financial position, results of operations, comprehensive income (loss), and cash flows of the Company after elimination of intercompany accounts and transactions, without audit and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair statement of the interim periods presented. Although certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") have been omitted, the Company believes that the disclosures included are adequate to make the information presented herein not misleading. Operating results for the third quarter and first nine months of 2013 and 2012 are not necessarily indicative of the results that may be expected for other interim periods or for any fiscal year. Certain amounts in the prior year's unaudited condensed consolidated financial statements have been reclassified to conform to the current period presentation.
	These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Company's annual report on Form 10-K for the fiscal year ended December 31, 2012 ("2012 Form 10-K") and Current Reports on Form 8-K as filed with the Securities and Exchange Commission ("SEC").
	New Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-04, Liabilities (“ASU 2013-04”), which is intended to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. ASU 2013-04 requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of (a) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (b) any additional amount the reporting entity expects to pay on behalf of its co-obligors. ASU 2013-04 also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. ASU 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and will be applied retrospectively to all prior periods presented for those obligations resulting from joint and several liability arrangements that exist at the beginning of an entity's fiscal year of adoption. The Company will adopt this pronouncement in the first quarter of 2014 and does not expect its adoption to have a material effect on its financial position or results of operations.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (“ASU 2013-02”), which is intended to improve the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The Company adopted ASU 2013-02 in the first quarter of 2013. The adoption of ASU 2013-02 had no effect on the Company's financial position or results of operations, but did impact the way the Company presented comprehensive income.

Acquisitions	'
	Acquisitions
	On April 1, 2013, the Company acquired all of the outstanding common stock of 2GIG Technologies, Inc. (“2GIG”) from APX Group, Inc. The purchase price was approximately $164.2 million, which consisted of a cash payment at the date of acquisition of approximately $135.0 million, working capital adjustments of approximately $13.9 million (of which approximately $12.3 million and $1.6 million were paid during the second and third quarter of 2013, respectively) and the settlement of a receivable due from 2GIG to the Company as of the acquisition date of approximately $15.3 million.
	2GIG is a designer and supplier of residential security and home automation systems. Developed with the assistance of Nortek's Linear® business, 2GIG's Go!Control® touch-screen panel is a self-contained, all-in-one home security and automation control panel. 2GIG also provides wireless interactive home security services and a wide range of peripheral hardware devices and system components for home security and automation solutions. The results of 2GIG have been included in the Company's results of operations since the date of acquisition and have been included in the Company's Technology Solutions ("TECH") segment.
	The following is a summary of the preliminary estimates of the assets acquired and liabilities assumed (amounts in millions):
	Current assets (1)	$	60.4
	Property and equipment, net	2.6
	Goodwill	68.5
	Intangible assets	84
	Other assets	0.1
	Accounts payable and accrued expenses	(20.1		)
	Deferred income taxes	(31.3		)
	Purchase price	$	164.2
	-1	Includes cash of approximately $3.4 million, accounts receivable of approximately $42.6 million, inventories of approximately $14.3 million, and other current assets of approximately $0.1 million. Inventories include a fair value adjustment to the historical carrying value of approximately $3.1 million, which was fully amortized in the second quarter of 2013.
	The excess of the purchase price paid over the fair value of 2GIG's net assets is recorded as goodwill, which is primarily attributable to opportunities for growth and profitability, as well as better positioning the Company in the growing residential security and home automation markets. The goodwill was recorded in the TECH reporting unit and the Company does not believe that any of the goodwill will be deductible for tax purposes.
	The Company has made preliminary estimates of the fair value of the assets and liabilities of 2GIG, including inventory, intangible assets, and prepaid and deferred taxes, utilizing information available at the time that the Company's unaudited condensed consolidated financial statements were prepared and these estimates are subject to refinement until all pertinent information has been obtained.
	The Company will complete the following procedures, among others, prior to finalizing the acquisition method of accounting for 2GIG:
	•	Finalize the appraisals of intangible assets.
	•	Finalize the deferred tax analysis for prepaid and deferred income taxes, including determining the deferred tax consequences for any changes in the fair value adjustments discussed above.
	The total preliminary fair value of intangible assets was approximately $84.0 million and the Company has determined that all of the intangible assets are subject to amortization and that they will have no residual value at the end of the amortization periods. The following is a summary of the estimated fair values and weighted average useful lives by intangible asset class (amounts in millions, except for weighted average useful lives):
			Fair Value		Weighted Average Useful Lives
	Customer relationships		$	73.1	10
	Completed technology		6.1		7
	Trademarks		4.8		10
			$	84	9.7
	Total intangible asset amortization for the second and third quarter of 2013 relating to 2GIG was approximately $4.3 million. Based upon current fair value estimates, annual amortization related to these acquired intangible assets is expected to be approximately $8.7 million.
	In connection with the acquisition of 2GIG, during the nine months of 2013, the Company also incurred approximately $1.7 million of acquisition fees and expenses, which have been recorded in selling, general and administrative expense, net ("SG&A") in the accompanying unaudited condensed consolidated statement of operations.
	The unaudited pro forma net sales, operating earnings, net earnings, basic and diluted earnings per share, and depreciation and amortization expense for the Company as a result of the acquisition of 2GIG for the periods presented were as follows:
			Year Ended		Nine months of
			Dec. 31, 2012		2013		2012
			(Dollar amounts in millions)
	Net sales		$	2,247.30	$	1,771.00	$	1,735.70
	Operating earnings		122.9		89.1		109.7
	Net earnings		5.3		7.4		19.4
	Basic earnings per share		0.35		0.48		1.28
	Diluted earnings per share		0.34		0.47		1.25
	Depreciation & amortization expense		96		69.4		72.6
	These amounts were determined assuming that the acquisition of 2GIG had occurred on January 1, 2012 and include preliminary pro forma adjustments to reflect (i) the elimination of intercompany transactions between the Company and 2GIG, (ii) additional depreciation and amortization expense related to the preliminary allocation of the purchase price, which is subject to change as the Company completes its review and appraisal work, (iii) increased interest expense related to the amounts borrowed to fund the acquisition and (iv) other pro forma adjustments that the Company considered appropriate related to the acquisition of 2GIG. The transaction costs of approximately $1.7 million related to the acquisition of 2GIG for the nine months of 2013 have been excluded from the unaudited pro forma operating earnings, net earnings, and basic and diluted earnings per share. These preliminary pro forma amounts are not necessarily indicative of the amounts that would have been achieved had the acquisition taken place as of January 1, 2012, nor are they necessarily indicative of the results for future periods. These preliminary pro forma financial statements are subject to change as additional information becomes available.
	On February 22, 2013, the Company, through an indirect wholly-owned foreign subsidiary, acquired certain assets and assumed certain liabilities of Gefen Distribution Verwaltungs GmbH ("Gefen Distribution") for total consideration of approximately $2.9 million, consisting of cash payments of approximately $0.9 million, a holdback amount of approximately $0.2 million to be paid 18 months subsequent to the closing of the acquisition, and the settlement of a receivable due from Gefen Distribution to the Company as of the acquisition date of approximately $1.8 million.  In connection with the acquisition of Gefen Distribution, during the second quarter of 2013, the Company also incurred approximately $0.3 million of acquisition fees and expenses, which have been recorded in SG&A in the accompanying unaudited condensed consolidated statement of operations. Gefen Distribution is the principal distributor of Gefen products in Europe and the acquisition expands the Company's European distribution of the Company's products. Gefen Distribution is included in the Company's TECH segment. The Company has made preliminary estimates of the purchase price and the fair value of the acquired assets and liabilities utilizing information available at the time that the Company's consolidated financial statements were prepared. These estimates are subject to refinement until all pertinent information has been obtained. Pro forma results related to the acquisition of Gefen Distribution have not been presented, as the effect is not significant to the Company's consolidated operating results.
	The incremental impact of the acquisition of 2GIG and Gefen Distribution contributed approximately $12.8 million to net sales and approximately $5.6 million (which includes depreciation and amortization expense of approximately $2.3 million) to operating earnings for the third quarter of 2013. The incremental impact of the acquisition of 2GIG and Gefen Distribution contributed approximately $71.4 million to net sales and approximately $11.7 million (which includes depreciation and amortization expense of approximately $8.0 million, including approximately $3.1 million relating to the amortization of fair value allocated to inventory) to operating earnings for the nine months of 2013.

Goodwill	'
	Goodwill
	The Company accounts for acquired goodwill in accordance with Accounting Standards Codification ("ASC") 805, "Business Combinations" ("ASC 805") and ASC 350, “Intangibles - Goodwill and Other” (“ASC 350”). Under ASC 350, goodwill is not amortized. Instead, it is evaluated for impairment on an annual basis, or more frequently when an event occurs or circumstances change between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying value, including, for example, a significant adverse change in the business climate. The Company has set the annual evaluation date as of the first day of its fiscal fourth quarter. The reporting units evaluated for goodwill impairment have been determined to be the same as the Company's operating segments. Only the RESV, DMS and TECH reporting units have goodwill and, therefore, are the only reporting units that currently are required to be evaluated for goodwill impairment.
	The following table presents a summary of the activity in goodwill by reporting segment for the nine months of 2013:
			Dec. 31, 2012		Acquisitions (1)		Sept. 28, 2013

Operational Improvement Initiatives [Abstract]	'
Operational Improvement Initiatives	'
	Operational Improvement Initiatives
	In 2012, the Company began operational improvement initiatives which it expects will result in significant improvements in efficiencies and reductions in operating costs and expenses, both in manufacturing processes and in administrative functions, which will better align the Company with the markets it serves and will improve its overall competitiveness. In addition to efficiencies and cost reductions, the Company expects that these initiatives will allow it to focus greater effort and resources on product development, marketing and sales, and customer service. The Company considers these initiatives to be important to its ability to maintain and improve its position in many of its markets and to allow it to expand in certain other markets. These initiatives address a wide variety of key areas of operations, including, for example, (i) optimizing the number and location of manufacturing, warehousing and distribution facilities, (ii) optimizing the Company's procurement sources and processes, (iii) determining the potential for leveraging administrative resources across various operating groups, (iv) combining and/or relocating individual operations to leverage common management, (v) implementing global information systems to facilitate communication and resource sharing in areas such as finance and human resources and (vi) introducing new products and expanding the Company's presence in certain markets. See Note F, "Exit and Disposal Activities", for further description surrounding the costs associated with certain of these activities.
	Given the wide ranging impact of these initiatives, the Company has made or plans to make significant incremental investments in staffing, research and development projects and specialized consulting resources, including engaging certain additional, third party resources with specialization in the areas of manufacturing rationalization, procurement, logistics and process optimization. The cost of these investments in external resources is expected to range from approximately $12.0 million to $14.0 million in 2013.
	During the third quarter and nine months of 2013, the Company recorded approximately $2.2 million and $10.8 million, respectively, of operational improvement initiative costs. There were approximately $2.0 million and $2.1 million of costs associated with these activities during the third quarter and nine months of 2012, respectively.

Commitments and Contingencies Disclosure [Abstract]	'
Commitments and Contingencies	'
	Commitments and Contingencies
	The Company provides accruals for all direct costs, including legal costs, associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. Costs accrued are estimated based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes. Legal costs for other than probable contingencies are expensed when services are performed.
	Indemnifications
	The Company has indemnified third parties for certain matters in a number of transactions involving dispositions of former subsidiaries, including certain pension and environmental liabilities.  The Company has recorded liabilities in relation to these indemnifications of approximately $5.3 million at each of September 28, 2013 and December 31, 2012, of which approximately $2.5 million and $2.3 million, respectively, are recorded in accrued expenses and approximately $2.8 million and $3.0 million, respectively, are recorded in other long-term liabilities in the accompanying unaudited condensed consolidated balance sheets.  At September 28, 2013 and December 31, 2012, the undiscounted future payments related to these indemnifications were estimated to be approximately $5.5 million and $5.7 million, respectively.
	Product Warranty and Recall Reserves
	The Company sells a number of products and offers a number of warranties including, in some instances, extended warranties for which the Company receives proceeds.  The specific terms and conditions of these warranties vary depending on the product sold and the country in which the product is sold.  The Company estimates the costs that may be incurred under its warranties, with the exception of extended warranties, and records a liability for such costs at the time of sale.  Deferred revenue from extended warranties is recorded at estimated fair value and is amortized over the life of the warranty and periodically reviewed to ensure that the amount recorded is equal to or greater than estimated future costs.  Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rates of warranty claims, cost per claim, and new product introductions.  The Company periodically assesses the adequacy of its recorded warranty claims and adjusts the amounts as necessary.
	Changes in the Company’s combined short-term and long-term warranty liabilities during the third quarter and nine months of 2013 and 2012 are as follows:
		Third quarter of						Nine months of
		2013			2012			2013			2012
		(Dollar amounts in millions)
	Balance, beginning of period	$	58		$	56		$	54.7		$	56.3
	Warranties provided during period	11.2			6.9			25.7			19.6
	Settlements made during period	(10.3		)	(7.4		)	(22.3		)	(21.7		)
	Other changes in liability estimate, including	0.5			0.8			1.3			2.1
	expirations and acquisitions
	Balance, end of period	$	59.4		$	56.3		$	59.4		$	56.3
	Other Commitments and Contingencies
	The Company is subject to other contingencies, including legal proceedings and claims, arising out of its businesses that cover a wide range of matters including, among others, environmental matters, contract and employment claims, product liability, warranty, and modification and adjustment or replacement of component parts of units sold, which include product recalls. Product liability, environmental and other legal proceedings also include matters with respect to businesses previously owned. The Company has used various substances in its products and manufacturing operations which have been or may be deemed to be hazardous or dangerous, and the extent of its potential liability, if any, under environmental, product liability and workers' compensation statutes, rules, regulations and case law is unclear. Furthermore, due to the lack of adequate information and the potential impact of present regulations and any future regulations, there are certain circumstances in which the amount or range of possible losses cannot be reasonably estimated.
	While it is impossible to ascertain the ultimate legal and financial liability with respect to contingent liabilities, including lawsuits, warranty, product liability, environmental liabilities, and product recalls, the Company believes that the aggregate amount of such liabilities, if any, in excess of amounts provided or covered by insurance, will not have a material adverse effect on the Company's consolidated financial position, results of operations or liquidity. It is possible, however, that results of operations for any particular future period could be materially affected by changes in the Company's assumptions or strategies related to these contingencies or changes that are not within the Company's control.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	Income Taxes
	The provision for income taxes for the third quarter of 2013 and 2012 was approximately $3.5 million and $5.5 million, respectively. The provision for income taxes for the nine months of 2013 and 2012 was approximately $2.8 million and $18.4 million, respectively. The effective income tax rate of approximately 82.4% for the nine months of 2013 differs from the United States federal statutory rate of 35% principally as a result of losses in certain jurisdictions that cannot be benefited and the settlement of an uncertain tax position during the first quarter of 2013. Compared to the United States federal statutory rate of 35%, the effective income tax rate of approximately 45.5% for the nine months of 2012 reflects an increase in the valuation allowances related to certain deferred tax assets, state tax expense, and nondeductible expenses, partially offset by a decrease due to the effect of foreign operations.
	The increase in valuation allowance relates to losses of certain foreign subsidiaries and losses in certain domestic jurisdictions. The Company has determined, based on the history of losses at these subsidiaries, that a valuation allowance is required for these loss carry-forwards since it is more likely than not that these loss carry-forwards will not be realized.
	As of January 1, 2013, the Company had a liability of approximately $26.4 million for unrecognized tax benefits related to various federal, foreign and state income tax matters.  As a result of additional provisions during the nine months of 2013 and reversals related to an audit settlement, the liability for uncertain tax positions at September 28, 2013 was approximately $27.5 million. The liability for uncertain tax positions is included in other long-term liabilities on the accompanying unaudited condensed consolidated balance sheet. The corresponding amount of gross uncertain tax benefits was approximately $35.0 million and $34.5 million at September 28, 2013 and December 31, 2012, respectively.
	As of September 28, 2013 and December 31, 2012, the amount of uncertain tax positions that will impact the Company's effective tax rate is approximately $14.8 million and $14.6 million, respectively. The difference between the total amount of uncertain tax positions and the amount that will impact the effective tax rate represents the federal tax effect of state tax items, items that offset temporary differences, and items that will result in the reduction of other tax assets.
	As of September 28, 2013, the Company had approximately $4.2 million in unrecognized benefits relating to various state and foreign tax issues, for which the statute of limitations is expected to expire in the fourth quarter of 2013. During the first quarter of 2013, the Company reached a settlement related to certain state income tax matters.  As a result, the Company settled total uncertain tax positions of approximately $2.3 million and related interest of approximately $0.8 million for approximately $0.7 million.  The settlement resulted in a tax benefit in the first quarter of 2013 of approximately $1.6 million, net of related federal tax effect.
	As of September 28, 2013 and December 31, 2012, the total amount of accrued interest related to uncertain tax positions was approximately $2.8 million and $2.8 million, respectively.  The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for federal and state taxes.

	The Company is a global, diversified company whose many market-leading brands deliver broad capabilities and a wide array of innovative, technology-driven products and solutions for lifestyle improvement at home and at work. The Company's five reporting segments are as follows:
	•	the Residential Ventilation (“RESV”) segment,
	•	the Technology Solutions (“TECH”) segment,
	•	the Display Mount Solutions ("DMS") segment,
	•	the Residential Heating and Cooling (“RHC”) segment, and
	•	the Custom & Engineered Solutions (“CES”) segment.
	For a description of the activities of the Company's reporting segments, see Note 9, "Segment Information and Concentration of Credit Risk", of the Company's 2012 Form 10-K.
	Through these segments, the Company manufactures and sells, primarily in the United States, Canada, and Europe, with additional manufacturing in China, a wide variety of products for the remodeling and replacement markets, the residential and commercial new construction markets, the manufactured housing market, and the personal and enterprise computer markets.
	The Company's performance is significantly impacted by the levels of residential remodeling and replacement activity, as well as the levels of new residential and non-residential construction. The level of new construction activity and, to a lesser extent, the level of residential remodeling and replacement activity are affected by seasonality and cyclical factors such as interest rates, inflation, consumer spending, employment levels, and other macroeconomic factors, over which the Company has no control. Performance in any particular period could be impacted by the timing of sales to certain large customers.
	The Company evaluates segment performance based on operating earnings before allocations of corporate overhead costs. Intersegment net sales and intersegment eliminations are not material for any of the periods presented. The financial statement impact of all purchase accounting adjustments, including intangible assets amortization and goodwill, are reflected in the applicable operating segments, which are the Company’s reporting units.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Fair Value
	The Company’s assets and liabilities recorded at fair value have been categorized based upon a fair value hierarchy in accordance with ASC 820, Fair Value Measurements. The levels of the fair value hierarchy are described below:
	•	Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets and liabilities that the Company has the ability to access at the measurement date.
	•	Level 2 inputs utilize inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals.
	•	Level 3 inputs are unobservable inputs for the asset or liability, allowing for situations where there is little, if any, market activity for the asset or liability.
	Measured on a Recurring Basis
	Restricted Investments and Marketable Securities (Level 1) -- The fair value of investments is based on quoted market prices.  The fair value of investments was not materially different from their cost basis at September 28, 2013 or December 31, 2012.
	Financial Instruments Not Recorded at Fair Value
	The carrying value and fair values of financial instruments not recorded at fair value in the unaudited condensed consolidated balance sheets at September 28, 2013 and December 31, 2012 were as follows:
	Cash and Trade Receivables -- Cash and trade receivables are carried at their cost which approximates fair value (Level 1) because of their short-term nature.
	Long-Term Debt -- At September 28, 2013, the fair value of the Company's long-term indebtedness was approximately $99.7 million higher than the amount on the Company's accompanying unaudited condensed consolidated balance sheet, before net unamortized premium of approximately $4.8 million. At December 31, 2012, the fair value of the Company’s long-term indebtedness was approximately $109.0 million higher than the amount on the Company's consolidated balance sheet, before net unamortized premium of approximately $5.3 million.  The Company determined the fair market value of its 10% Notes and 8.5% Notes using available market quotes (Level 1). For the Company's remaining outstanding indebtedness (including outstanding borrowings under the ABL Facility and the Term Loan Facility), the Company assumed that the carrying value of such indebtedness approximated the fair value based upon the variable interest rates associated with certain of these debt obligations and the Company's estimated credit risk.
