SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	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 principal reporting segments (see Note 9, “Segment Information and Concentration of Credit Risk”), the Company manufactures and sells, primarily in the United States, Canada and Europe, with additional manufacturing in China and Mexico, a wide variety of products principally for the remodeling and replacement markets, the residential and commercial new construction markets, and the personal and enterprise computer markets.
	The accompanying 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. As a result of certain acquisitions as discussed in Note 2, “Acquisitions”, the operating results of these acquired entities are included in the Company’s consolidated results of operations from the date of acquisition prospectively. The Company has entered into certain arrangements with an independent third party in Mexico related to the Company’s manufacturing operations in Mexico. The Company has evaluated the operating entities that were formed under these arrangements and has determined that these entities are variable interest entities in accordance with Accounting Standards Codification ("ASC") 810, "Consolidation" ("ASC 810"). The Company has concluded that it is the primary beneficiary of these entities since it has both the power to direct activities that most significantly impact the entities' economic performance and the obligation to absorb losses that could potentially be significant since the Company is responsible for all operating decisions and all operating costs of these entities. As a result, the Company is consolidating the results of these entities in accordance with ASC 810. For the year ended December 31, 2014, the results of operations of these entities included in the Company’s statement of operations were not material.
	Certain amounts in the prior year's consolidated financial statements have been reclassified to conform to the current year presentation and to correct the classification of certain immaterial amounts. See Note 16, “Summarized Quarterly Financial Data (Unaudited)” for a summary of the quarterly and annual impact. In addition, the Company has corrected the disclosure of issued shares of common stock on its consolidated balance sheet, consolidated statements of stockholders’ investment, and in Note 10, "Equity Activity", to properly include awarded, but unvested restricted stock that has been legally issued.  This resulted in an increase in the number of shares of common stock issued and outstanding by 468,048 shares, 555,224 shares and 466,852 shares as of December 31, 2013, 2012 and 2011, respectively.
	During the second quarter of 2014, the Company changed the composition of its reporting segments to exclude the audio, video and control ("AVC") entities (formerly the "AV entities") from the Security and Control Solutions ("SCS") segment due to the Chief Operating Decision Maker's decision to operate each of these entities separately and manage each as a standalone segment. As a result, the Company has restated prior period segment disclosures to conform to the new composition. The AVC entities have been combined and have not been reported separately as these operating segments are individually not significant (the "AVC segments"). These entities were principally acquired at various times from 2003 to 2011. See Note 3, “Goodwill and Other Intangible Assets”.
	Accounting Policies and Use of Estimates
	The preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles involves estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expense during the reporting periods. Certain of the Company’s accounting policies require the application of judgment in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. The Company periodically evaluates the judgments and estimates used for its critical accounting policies to ensure that such judgments and estimates are reasonable for its interim and year-end reporting requirements. These judgments and estimates are based on the Company’s historical experience, current trends and information available from other sources, as appropriate. If different conditions result from those assumptions used in the Company’s judgments, the results could be materially different from the Company’s estimates.
	Recognition of Sales and Related Costs, Incentives and Allowances
	The Company generally recognizes sales when passage of title and risk of loss to the customer occurs, which is typically upon shipment, and has procedures in place at each of its subsidiaries to ensure that an accurate cut-off is obtained for each reporting period. The Company considers revenue to be realized or realizable and earned when all of the following criteria are met: persuasive evidence of a sales arrangement exists; delivery has occurred or services have been rendered; the price is fixed or determinable; and collectability is reasonably assured.
	Certain of the Company's arrangements with its customers, principally in the Commercial Air Solutions ("CAS") segment, are multiple-element arrangements that can include any combination of products and services such as extended warranties, installation and start up testing as deliverables. With the exception of certain extended warranty arrangements, substantially all of the deliverables within the Company’s multiple element arrangements are delivered within a one year period. In accordance with ASC 605-25, "Revenue Recognition", the Company believes that any undelivered elements can be accounted for separately from the delivered element when the delivered elements have value to its customers on a stand-alone basis. Accordingly, revenue for an undelivered element is deferred until delivery occurs. The Company is required to allocate revenue to multiple element arrangements based on the relative fair value of each element’s estimated selling price. The Company uses vendor-specific objective evidence (“VSOE”), if available, to determine the selling price of each element. The Company determines VSOE based on its normal pricing and discounting practices for the specific product or service when sold on a stand-alone basis. In determining VSOE, the Company's policy requires a substantial majority of selling prices for a product or service to be within a reasonably narrow range. The Company also considers the class of customer, method of distribution, and the geographies into which its products and services are sold when determining VSOE. If VSOE is not available, the Company uses third-party evidence or its best estimated selling price to determine the selling price for each element.
	Allowances for cash discounts, volume rebates, other customer incentive programs and gross customer returns, among others, are recorded as of the later of the date at which the revenues are recognized or the incentive is offered and are generally recorded as a reduction of sales at the time of sale based upon the estimated future outcome. Certain customer incentives are recorded as a charge to selling, general and administrative expense, net (“SG&A”) if there is a separable, identifiable benefit related to the incentive that can be quantified. These customer incentives principally relate to promotional advertising allowances where the customer is required to obtain approval and provide support for the associated advertising expenditures in order to receive the incentive consideration. Cash discounts, volume rebates and other customer incentive programs are based upon certain percentages agreed to with the Company’s various customers, which are typically earned by the customer over an annual period. The Company records periodic estimates for these amounts based upon the historical results to date, estimated future results through the end of the contract period, and the contractual provisions of the customer agreements. For calendar year customer agreements, the Company is able to adjust its periodic estimates to actual amounts as of December 31 each year based upon the contractual provisions of the customer agreements. For those customers who have agreements that are not on a calendar year cycle, the Company records estimates at December 31 consistent with the above described methodology. Customers are generally not required to provide collateral for purchases. As a result, at the end of any given reporting period, the amounts recorded for these allowances are based upon estimates of the likely outcome of future sales with the applicable customers and may require adjustment in the future if the actual outcome differs. The Company believes that its procedures for estimating such amounts are reasonable.
	Certain of the Company’s arrangements provide for rights of returns. Customer returns are recorded on an actual basis throughout the year and also include an estimate at the end of each reporting period for future customer returns related to sales recorded prior to the end of the period. The Company generally estimates customer returns based upon the time lag that historically occurs between the date of the sale and the date of the return, while also factoring in any new business conditions that might impact the historical analysis, such as new product introductions. The Company believes that its procedures for estimating such amounts are reasonable and allow it to make reliable estimates which are based on a historical large, homogeneous pool of transactions and history of returns. If a reliable estimate of returns cannot be made, the Company defers revenues until the right of return lapses. If the Company defers the recognition of arrangement consideration due to the fact that the criteria for revenue recognition are not achieved, the Company also defers the recognition of the related direct and incremental costs, primarily product costs, and recognizes such costs upon recognition of the corresponding deferred revenues. The amount of deferred direct and incremental costs at December 31, 2014 and 2013, respectively, was not material.
	The Company also provides for its estimate of warranty, bad debts and shipping costs at the time of sale. Shipping and warranty costs are included in cost of products sold ("COGS"). Provisions for the estimated allowance for doubtful accounts are recorded in SG&A. The amounts recorded are generally based upon historically derived percentages while also factoring in any new business conditions that might impact the historical analysis such as changes in economic conditions, past due and nonperforming accounts, bankruptcies or other events affecting particular customers. The Company periodically evaluates the adequacy of its allowance for doubtful accounts recorded in its consolidated balance sheet to ensure the adequacy of the recorded provisions. The analysis for allowance for doubtful accounts often involves subjective analysis of a particular customer’s ability to pay. As a result, significant judgment is required in determining the appropriate amounts to record and such judgments may prove to be incorrect in the future. The Company believes that its procedures for estimating such amounts are reasonable.
	Cash and Cash Equivalents
	Cash equivalents consist of short-term highly liquid investments with original maturities of three months or less which are readily convertible into cash.
	The Company has classified as restricted in the accompanying consolidated balance sheet certain cash and cash equivalents that are not fully available for use in its operations. At December 31, 2014 and 2013, the Company had cash and cash equivalents pledged as collateral or held in pension trusts for certain debt, insurance, employee benefits and other requirements of approximately $1.5 million (of which approximately $0.9 million is included in long-term assets) and approximately $4.5 million (of which approximately $1.6 million is included in long-term assets), respectively.
	Inventories
	Inventories in the accompanying consolidated balance sheet are valued at the lower of cost or market. At December 31, 2014, approximately $127.7 million of the Company's total inventories were valued on the last-in, first-out method (“LIFO”) of accounting. Under the first-in, first-out method (“FIFO”), such inventories would have been approximately $1.7 million lower at December 31, 2014. At December 31, 2013, approximately $78.4 million of the Company's total inventories were valued under LIFO. Under FIFO, such inventories would have been approximately $0.7 million lower at December 31, 2013. All other inventories were valued under the FIFO method.
	In connection with both LIFO and FIFO inventories, the Company records provisions, as appropriate, to write-down obsolete and excess inventory to estimated net realizable value. The process for evaluating obsolete and excess inventory often requires the Company to make subjective judgments and estimates concerning future sales levels, quantities, and prices at which such inventory will be able to be sold in the normal course of business. Accelerating the disposal process or incorrect estimates of future sales potential may cause the actual results to differ from the estimates at the time such inventory is disposed or sold.
	Inventory acquired in business combinations is recorded to cost of products sold over the period in which the inventory will be sold.
	Depreciation and Amortization
	Depreciation and amortization of property and equipment, including capital leases, is provided on a straight-line basis over their estimated useful lives, which are generally as follows:
	Buildings and improvements	3 - 43 years
	Machinery and equipment, including leases	1 - 13 years
	Leasehold improvements	Shorter of the original lease term or the estimated useful life
	Expenditures for maintenance and repairs are expensed when incurred. Expenditures for renewals and betterments are capitalized. When assets are sold, or otherwise disposed, the cost and related accumulated depreciation are eliminated and the resulting gain or loss is recognized.
	During 2013, the Company recorded a non-cash addition to buildings within property and equipment and other long-term liabilities of approximately $33.6 million related to construction in progress of new facilities in Mexico (see Note 6, "Commitments and Contingencies").
	Goodwill and Other Intangible Assets
	The Company accounts for acquired goodwill in accordance with ASC 805, "Business Combinations" ("ASC 805") and ASC 350, “Intangibles - Goodwill and Other” (“ASC 350”), which involves judgment with respect to the determination of the valuation of the acquired assets and liabilities assumed in order to determine the final amount of goodwill recorded in a purchase. See Note 3, “Goodwill and Other Intangible Assets”, for a discussion of these judgments.
	Pensions and Post-Retirement Health Benefits
	The Company accounts for pensions and post-retirement health benefits in accordance with ASC 715, “Compensation - Retirement Benefits,” (“ASC 715”). The accounting for pensions requires the estimation of items such as the long-term average return on plan assets, the discount rate, the rate of compensation increase, and the assumed medical cost inflation rate. Such estimates require a significant amount of judgment. See Note 13, “Pension, Profit Sharing and Other Post-Retirement Benefits”, for a discussion of these judgments.
	Insurance Liabilities
	The Company records insurance liabilities and related expenses for health, workers compensation, product and general liability losses, and other insurance reserves and expenses in accordance with either the contractual terms of its policies or, if self-insured, the total liabilities that are estimable and probable as of the reporting date. Insurance liabilities are recorded as current liabilities to the extent they are expected to be paid in the succeeding year, with the remaining requirements classified as long-term liabilities. The accounting for self-insured plans requires that significant judgments and estimates be made both with respect to the future liabilities to be paid for known claims, and incurred but not reported claims as of the reporting date. The Company considers historical trends when determining the appropriate insurance liabilities to record in the consolidated balance sheet for a substantial portion of its workers compensation and general and product liability losses. In certain cases where partial insurance coverage exists, the Company must estimate the portion of the liability that will be covered by existing insurance policies to arrive at the net expected liability to the Company. Receivables for insurance recoveries for product liability claims are recorded as assets, on an undiscounted basis. These recoveries are estimated based on the contractual arrangements with vendors and other third parties, and historical trends.
	Income Taxes
	The Company accounts for income taxes using the liability method in accordance with ASC 740, “Income Taxes” (“ASC 740”), which requires that the deferred tax consequences of temporary differences between the amounts recorded in the Company’s consolidated financial statements, and the amounts included in the Company’s federal, state and foreign income tax returns, be recognized in the balance sheet. As the Company generally does not file its income tax returns until well after the closing process for the December 31 financial statements is complete, the amounts recorded at December 31 reflect estimates of what the final amounts will be when the actual income tax returns are filed for that fiscal year. In addition, estimates are often required with respect to, among other things, the appropriate state income tax rates to use in the various states that Nortek and its subsidiaries are required to file, the potential utilization of operating and capital loss carry-forwards, and valuation allowances required, if any, for tax assets that may not be realizable in the future. ASC 740 requires balance sheet classification of current and long-term deferred income tax assets and liabilities based upon the classification of the underlying asset or liability that gives rise to a temporary difference (see Note 8, “Income Taxes”). The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for income taxes.
	Share-Based Compensation Expense
	The Company measures share-based compensation expense at fair value in accordance with ASC 718, “Compensation - Stock Compensation” (“ASC 718”), and recognizes such expense, net of estimated forfeitures, over the vesting period of the share-based awards. See Note 12, “Share-Based Compensation”, for further information regarding the Company's share-based compensation programs.
	Exit and Disposal Activities
	The Company accounts for termination benefits based on the nature of the underlying arrangement. In instances where the Company has a defined plan, a past practice of providing a similar level of benefits or a statutorily defined termination benefit arrangement, the Company recognizes a liability for ongoing termination benefits when it is probable the employees will be entitled to the benefits and the amount can be reasonably estimated.
	In instances where the Company provides termination benefits and an ongoing arrangement does not exist, the timing of measurement of a liability for one-time employee termination benefits depends on whether employees are required to render service until they are terminated in order to receive the termination benefits and, if so, whether employees will be retained to render service beyond a minimum retention period. If employees are not required to render service until they are terminated in order to receive the termination benefits (that is, if employees are entitled to receive the termination benefits regardless of when they leave) or if employees will not be retained to render service beyond the minimum retention period, a liability for the termination benefits is measured and recognized at its fair value at the communication date. If employees are required to render service until they are terminated in order to receive the termination benefits and will be retained to render service beyond the minimum retention period, a liability for the termination benefits is measured initially at the communication date based on the fair value of the liability as of the termination date and recognized ratably over the future service period.
	A liability, measured at its fair value, for costs to terminate a contract before the end of its term is recognized when the Company terminates the contract in accordance with the contract terms. A liability for costs that will continue to be incurred under a contract for its remaining term without economic benefit to the Company is recognized at the cease-use date. If the contract is an operating lease, the fair value of the liability at the cease-use date is determined based on the remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized under the lease, and reduced by estimated sublease rentals that could be reasonably obtained for the property, even if the Company does not intend to enter into a sublease. Remaining lease rentals are not reduced to an amount less than zero.
	Other costs associated with an exit or disposal activity include, but are not limited to, costs to consolidate or close facilities and relocate employees. A liability for other costs associated with an exit or disposal activity is measured and recognized at its fair value in the period in which the liability is incurred (generally, when goods or services associated with the activity are received).
	See Note 5, “Exit and Disposal Activities”, for further information regarding the Company’s exit and disposal activities.
	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. See Note 6, “Commitments and Contingencies”, for further information regarding the Company’s commitments and contingencies.
	Research and Development
	The Company’s research and development activities are principally related to new product development. Recorded in SG&A, research and development costs were approximately $75.4 million, $65.5 million and $59.4 million for 2014, 2013 and 2012, respectively, and represented approximately 3.0%, 2.9%, and 2.7% of the Company’s consolidated net sales for 2014, 2013 and 2012, respectively.
	Foreign Currency Translation
	The financial statements of subsidiaries located outside of the United States are generally measured using the foreign subsidiary's local currency as the functional currency. The Company translates the assets and liabilities of its foreign subsidiaries at the exchange rates in effect at year-end. Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive income (loss) included in stockholders’ investment. Net sales, costs and expenses are translated using average exchange rates in effect during the year. Transaction gains and losses are recorded in SG&A.
	New Accounting Pronouncements
	In August 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40) ("ASU 2014-15"), which provides guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The amendments require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term "substantial doubt", (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and early adoption is permitted. The Company will adopt this pronouncement in the first quarter of 2017 and does not expect adoption to have a material effect on the Company's consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718) ("ASU 2014-12"), which clarifies the accounting for share based payments in which the terms of the award provide that a performance target can be achieved after the requisite service period. ASU 2014-12 is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted and an entity may apply the amendments in ASU 2014-12 either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Company will adopt this pronouncement in the first quarter of 2016 and is currently evaluating the impact, if any, adoption will have on its financial position and results of operations.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 is a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle under ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also specifies the accounting for some costs to obtain or fulfill a contract with a customer. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted and an entity may apply the amendments in ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 at the date of initial application. The Company will adopt this pronouncement in the first quarter of 2017 and is currently evaluating both the method of adoption and the impact adoption will have on its financial position and results of operations. In evaluating the method of adoption, the Company is considering a number of factors, including the disclosure requirements and related processes and controls required, as well as, the overall industry and peer public company adoption method trends.
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08"), which changes the criteria for reporting discontinued operations. ASU 2014-08 will also require additional disclosures about discontinued operations including, among others, the major classes of line items constituting the pretax profit and loss of the discontinued operation, either the total operating and investing cash flow of the discontinued operation or the depreciation, amortization, capital expenditures, and significant operating and investing non-cash items of the discontinued operation, a reconciliation of the major classes of assets and liabilities of the discontinued operation classified as held for sale to total assets and total liabilities of the disposal group classified as held for sale that is presented on the face of the balance sheet, and a reconciliation of the major classes of line items constituting the pretax profit or loss of the discontinued operation to the after-tax profit or loss of the discontinued operation that is presented on the face of the income statement. ASU 2014-08 also requires entities to provide disclosures about a disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation and expands the disclosures about an entity's significant continuing involvement with a discontinued operation. ASU 2014-08 is effective prospectively for both (1) disposals of components of an entity and (2) businesses that, on acquisition are classified as held for sale, that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. As of December 31, 2014, there have been no disposals or classifications as held for sale that would be subject to ASU 2014-08. As such, the Company will adopt this standard in the first quarter of 2015.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (“ASU 2013-11”), which is intended to provide guidance regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The standard clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when certain situations exist at the reporting date and is effective for annual reporting periods beginning on or after December 15, 2013 and subsequent interim periods, with early adoption permitted. The adoption of this standard did not have a material effect on the Company's consolidated financial statements.
	In February 2013, the FASB issued 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 adoption of this standard did not have a material effect on the Company's financial position or results of operations.

ACQUISITIONS	ACQUISITIONS
	Reznor Acquisition
	On April 30, 2014, the Company completed the acquisition of the heating, ventilation and air conditioning business of Thomas & Betts Corporation ("Reznor") for approximately $260.0 million in cash, plus additional payments of approximately $2.6 million for working capital and other post-closing adjustments, of which approximately $1.9 million was paid in the second quarter of 2014 and approximately $0.7 million was paid during the fourth quarter of 2014. The acquisition was financed with a combination of cash on hand and a portion of the borrowings under a new $350.0 million senior secured term loan facility (see Note 4, "Notes, Mortgage Notes and Obligations Payable").
	Reznor manufactures industrial and commercial HVAC products, including an extended range of gas fired air heaters, air handling units, condensing units and rooftop units. The results of Reznor have been included in the Company's results of operations since the date of acquisition and have been included in the Company's Residential and Commercial HVAC ("RCH") segment.
	The following is a summary of the accounting for the fair value of the assets acquired and liabilities assumed (dollar amounts in millions):
	Current assets (1)	$	47.3
	Property and equipment	17
	Goodwill	103.7
	Intangible assets	124.3
	Other assets	0.4
	Current liabilities (2)	(18.8		)
	Deferred income taxes	(9.7		)
	Other long-term liabilities	(1.6		)
		$	262.6
	-1	Includes cash of approximately $7.0 million, accounts receivable of approximately $17.5 million, inventories of approximately $20.5 million, prepaid and other current assets of approximately $1.4 million, and current deferred taxes of approximately $0.9 million. Inventories include a fair value adjustment to the historical carrying value of approximately $1.8 million, which increased cost of products sold for 2014.
	-2	Includes accounts payable of approximately $12.3 million and accrued expenses and taxes of approximately $6.5 million.
	The excess of the purchase price paid over the fair value of Reznor's net assets is recorded as goodwill, which is primarily attributable to the Company's belief that the acquisition of Reznor positions Nortek to service a broader portion of the HVAC market. Approximately $76.1 million of goodwill associated with the acquisition will be deductible for income tax purposes.
	The Company has made estimates of the fair value of the assets and liabilities of Reznor, including inventory, property and equipment, and intangible assets utilizing information available at the time that the Company's consolidated financial statements were prepared. These non-recurring fair value measurements are primarily determined using unobservable inputs. Accordingly, these fair value measurements are classified within Level 3 of the fair value hierarchy. The Company is in the process of gathering information to finalize the appraisal of certain assets and the related deferred tax consequences, which will be completed in the first quarter of 2015.
	The total fair value of intangible assets was approximately $124.3 million. 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 (dollar amounts in millions):
			Fair Value			Weighted Average Useful Lives
	Customer relationships		$	64.2		11.1
	Completed Technology		20.4			5
	Trademarks		39.7			20
			$	124.3		12.9
	Total intangible asset amortization for 2014 relating to Reznor was approximately $8.1 million. The estimated future intangible asset amortization expense related to these acquired intangible assets is expected to aggregate approximately $116.2 million as follows:
	Year Ended December 31,		Annual Amortization Expense
			(Dollar amounts in millions)
	2015		$	12.1
	2016		12.1
	2017		12.1
	2018		12.1
	2019		9.4
	2020 and thereafter		58.4
	In connection with the acquisition of Reznor, the Company also incurred approximately $6.8 million of fees and expenses, which have been recorded in selling, general and administrative expense, net ("SG&A") in the accompanying consolidated statement of operations for 2014.
	The unaudited pro forma net sales, operating earnings, net loss, basic and diluted loss per share, and depreciation and amortization expense for the Company as a result of the acquisition of Reznor for the periods presented were as follows:
			Year Ended
			2014			2013
			(Dollar amounts in millions, except per share data)
	Net sales		$	2,598.20		$	2,447.10
	Operating earnings		55.7			98.8
	Net loss		(37.6		)	(6.0		)
	Basic loss per share		(2.40		)	(0.39		)
	Diluted loss per share		(2.40		)	(0.39		)
	Depreciation & amortization expense		108.9			112.8
	These amounts were determined assuming that the acquisition of Reznor had occurred on January 1, 2013 and include pro forma adjustments to reflect (i) additional depreciation and amortization expense related to the estimates of the fair values of acquired tangible and intangible assets, (ii) changes in interest expense related to financing transactions due, in part, to funding the acquisition, and (iii) other pro forma adjustments that the Company considered appropriate related to the acquisition of Reznor. The transaction costs of approximately $6.8 million related to the acquisition of Reznor for 2014 have been excluded from the unaudited pro forma operating earnings, net loss, and basic and diluted loss per share. These pro forma amounts are not necessarily indicative of the amounts that would have been achieved had the acquisition taken place as of January 1, 2013, nor are they necessarily indicative of the results for future periods.
	The acquisition of Reznor contributed approximately $117.0 million to net sales for 2014 and approximately $7.7 million (which includes depreciation and amortization expense of approximately $12.3 million, including approximately $1.8 million of increased cost of goods sold due to the recognition of inventory at its acquisition date fair value) to operating earnings for 2014.
	Phoenix Acquisition
	On October 8, 2014, one of the Company's subsidiaries in the RCH segment completed the acquisition of substantially all of the assets of the HVAC distribution business of privately owned Phoenix Wholesale, Inc. ("Phoenix"). This acquisition advances the Company's strategy of expanding the RHC segment’s distribution footprint in regions where the Company had minimal market penetration.  As a result of the acquisition of Phoenix, the Company now has 12 Company-owned distribution locations.
	The Company acquired this business for an aggregate purchase price of approximately $13.9 million, all of which was paid in cash. Approximately $1.6 million of the purchase price was retained by the Company as deferred acquisition consideration to be paid upon finalization of certain working capital and other purchase price adjustments and is included in accrued expenses and taxes, net in the Company’s consolidated balance sheet as of December 31, 2014.  These working capital and other purchase price adjustments were finalized and paid in February 2015.  In addition, approximately $1.0 million of the purchase price is held in escrow to cover general business representations and warranties. This amount will be paid 18 months after the closing date.  This acquisition did not have any earn-outs or other contingent purchase price consideration arrangements.
	Based on the Company’s evaluation of the assets and liabilities acquired, the Company determined that the fair value of tangible net assets acquired was approximately $8.2 million, including a fair value adjustment related to inventory acquired of approximately $0.4 million which was recognized in cost of products sold during the three month period ended December 31, 2014.  In addition, the Company recognized approximately $0.3 million of other assets related to a transition services agreement entered into in connection with the acquisition, which fair value is being expensed over the applicable one year service period.  In addition, approximately $3.9 million was recognized for definite-lived intangible assets, including customer relationships, trade names, non-compete arrangements and a favorable lease arrangement, with a weighted average useful life of approximately 7.8 years. Approximately $1.5 million was recorded to goodwill.  The Company is in the process of gathering information to complete its valuation of certain assets and liabilities in order to complete its accounting for the acquisition.
	The factors contributing to the recognition of goodwill were based upon the Company’s determination that several strategic and synergistic benefits are expected to be realized from the combination. Substantially all of the goodwill is expected to be deductible for tax purposes.
	The acquisition of Phoenix contributed approximately $4.0 million to net sales for 2014 and an operating loss of approximately $1.6 million (which includes depreciation and amortization expense of approximately $0.6 million, including approximately $0.4 million of increased cost of goods sold due to the recognition of inventory at its acquisition date fair value) to operating earnings for 2014.
	The results of Phoenix have been included in the Company’s consolidated financial statements since the date of acquisition within the RCH segment. Pro forma results related to the acquisition of Phoenix have not been presented, as the effect is not significant to the Company's consolidated operating results.
	2GIG Acquisition
	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 SCS segment. During 2013, the operations of 2GIG were integrated into the Company's existing security and access control products business, as such, net sales and operating earnings for 2014 for 2GIG have not been presented separately.
	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 2013 were as follows (dollar amounts in millions):
	Net sales		$	2,319.90
	Operating earnings		99.5
	Net loss		(1.5		)
	Basic loss per share		(0.10		)
	Diluted loss per share		(0.10		)
	Depreciation & amortization expense		94.8
	These amounts were determined assuming that the acquisition of 2GIG had occurred on January 1, 2013 and include pro forma adjustments to reflect (i) the elimination of intercompany transactions between the Company and 2GIG, (ii) additional depreciation and amortization expense related to acquired assets, (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 $1.8 million related to the acquisition of 2GIG for 2013 have been excluded from the unaudited pro forma operating earnings, net earnings, and basic and diluted earnings per share. These pro forma amounts are not necessarily indicative of the amounts that would have been achieved had the acquisition taken place as of January 1, 2013, nor are they necessarily indicative of the results for future periods.
Anthro Acquisition
On January 21, 2015, one of the Company’s wholly-owned subsidiaries completed an acquisition of 100% of the stock of Anthro Corporation (“Anthro”), a fully integrated business with in-house capability to design/develop, manufacture and market its technology furniture products.  Anthro's key products include charging carts (for electronics, including tablets, laptops and other mobile devices) and height adjustable desks and technology carts.  Anthro will be integrated into the Company’s Ergonomic and Productivity Solutions (“ERG”) segment.  The Company completed the acquisition of Anthro to expand its technology and product offerings of the ERG segment.
The Company acquired Anthro for an aggregate initial all cash purchase price of approximately $50.0 million, plus an initial payment of approximately $0.8 million for certain net working capital adjustments.  Approximately $5.0 million of the cash paid at closing was deposited into an escrow account with a third party escrow agent.  The initial payment related to the estimated net working capital acquired is subject to adjustment within 60 days subsequent to the closing. This acquisition did not have any earn-outs or other contingent purchase price consideration arrangements. Although this represented a stock purchase, it will be treated as a purchase of assets for income tax purposes.  It is expected that substantially all of the goodwill will be deductible for income tax purposes.  Pro forma results related to the acquisition of Anthro have not been presented, as the effect is not significant to the Company's consolidated operating results.
Other Acquisitions
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, and the settlement of a receivable due from Gefen Distribution to the Company as of the acquisition date of approximately $1.8 million.  Gefen Distribution is the principal distributor of Gefen products in Europe. Gefen Distribution is included in the Company's AVC segments. 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.
On December 17, 2010, the Company acquired all of the outstanding stock of Ergotron, Inc. (“Ergotron"). Ergotron is a designer, manufacturer and marketer of innovative, ergonomic mounting and mobility products for computer monitors, notebooks and flat panel displays in the United States and other parts of the world. The purchase price was approximately $299.6 million, consisting of cash payments totaling approximately $298.2 million, of which approximately $2.6 million was paid in 2012 primarily related to the reimbursement of federal and state tax refunds for the pre-acquisition period.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	GOODWILL AND OTHER INTANGIBLE ASSETS
	Goodwill
	The Company accounts for acquired goodwill in accordance with ASC 805 and ASC 350, which involves judgment with respect to the determination of the valuation of the acquired assets and liabilities assumed in order to determine the final amount of goodwill recorded in a purchase. 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. With the exception of the CAS reporting unit and the AVC entities, all of the Company's reporting units have goodwill and, therefore, are required to be evaluated for goodwill impairment.
	Generally, the Company utilizes a combination of a discounted cash flow (“DCF”) approach and an EBITDA multiple approach in order to value the Company's reporting units required to be tested for impairment. These non-recurring fair value measurements are primarily determined using unobservable inputs. Accordingly, these fair value measurements are classified within Level 3 of the fair value hierarchy.
	The DCF approach requires that the Company forecast future cash flows of the reporting units, and discount those cash flow streams based upon a weighted average cost of capital (“WACC”) that is derived, in part, from comparable companies within similar industries. The DCF calculations also include a terminal value calculation that is based upon an expected long-term growth rate for the applicable reporting unit. The Company believes that its procedures for estimating DCF, including the terminal valuation, are reasonable and consistent with market conditions at the time of estimation.
	The EBITDA multiple approach requires that the Company estimate certain valuation multiples of EBITDA derived from comparable companies, and apply those derived EBITDA multiples to the applicable reporting unit's estimated EBITDA for selected EBITDA measurement periods.
	2014 Interim Goodwill Impairment Testing
	During the second quarter of 2014, the Company changed the composition of its reporting units to exclude the AVC subsidiaries from the SCS reporting unit due to the Chief Operating Decision Maker's decision to operate each of the AVC subsidiaries as separate operating segments, resulting in the creation of three new reporting units for goodwill impairment analysis. In addition, due to the continued decline in operating results of the AVC subsidiaries, the Company concluded in the second quarter of 2014 that indicators of potential long-lived assets and goodwill impairment were present. Based on these considerations, the Company performed the following:
	1	Evaluation of the realizability of long-lived assets - In accordance with ASC 360, “Property, Plant and Equipment” (“ASC 360”), the Company evaluates the realizability of long-lived assets, which primarily consists of property and equipment and definite lived intangible assets (the “ASC 360 Long-Lived Assets”), when events or business conditions warrant it, as well as whenever an interim goodwill impairment test is required under ASC 350. ASC 350 requires that the ASC 360 impairment test be completed, and any ASC 360 impairment be recorded, prior to performing the goodwill impairment test. Due to the continued decline in operating results of the AVC subsidiaries, the Company performed an interim test for the impairment of long-lived assets.
	The evaluation of the impairment of long-lived assets, other than goodwill, is based on expectations of non-discounted future cash flows compared to the carrying value of the long-lived asset groups. If the sum of the expected non-discounted future cash flows is less than the carrying amount of the ASC 360 Long-Lived Assets, the Company would recognize an impairment loss if the carrying amount of the asset group exceeds its fair value. The Company's cash flow estimates are based upon future projected cash flows and, if appropriate, include assumed proceeds upon sale of the asset group at the end of the cash flow period. The Company believes that its procedures for estimating gross future cash flows, including the estimated sales proceeds, are reasonable and consistent with current market conditions for each of the dates when impairment testing has been performed.
	Based upon this analysis, the Company recorded a long-lived asset impairment loss of approximately $76.0 million related to the AVC subsidiaries, comprised of intangible assets of approximately $74.7 million and property and equipment of approximately $1.3 million, during the second quarter of 2014. The impairment loss related to intangible assets by class and the applicable weighted average useful lives were as follows:
					Weighted Average Useful Lives
	Customer relationships		$	48	16.2
	Trademarks		19.6		12.7
	Developed technology		6.1		6.3
	Other		1		7.9
			$	74.7	13
	The Company believes that impairment losses were reasonable and represented its best estimate of the impairment loss. If market conditions deteriorate further for these entities, it is reasonably possible that the estimate of expected future cash flows may change in the near term, resulting in an additional impairment charge relating to property and equipment.
	2	Evaluation of the legacy Technology Solutions ("TECH") reporting unit for goodwill impairment - As a result of the impairment indicators described above, the Company estimated the fair value of the legacy TECH reporting unit based upon an EBITDA multiple approach. Based on this estimate, the estimated fair value of the legacy TECH reporting unit exceeded the carrying value of the legacy TECH reporting unit. As a result, the Company did not believe that it was more likely than not that an impairment of the legacy TECH reporting unit goodwill had occurred.
	3	Allocation of the legacy TECH goodwill to each of the AVC subsidiaries - The Company estimated the fair value of each of the AVC subsidiaries based upon a DCF approach, as previously described, and allocated a portion of the legacy SCS goodwill to each of the AVC subsidiaries based upon their relative fair value.
	4	Evaluation of the revised SCS reporting unit and each of the AVC subsidiaries reporting units for goodwill impairment - During the second quarter of 2014, the Company prepared a “Step 1” Test that compared the estimated fair value of the AVC reporting units to their carrying value utilizing a DCF approach as described previously. As the carrying values of the AVC reporting units exceeded the estimated fair values, the Company performed a “Step 2” Test to measure the impairment loss by allocating the estimated fair values of the reporting units, as determined in Step 1, to the reporting units’ assets and liabilities, with the residual amount representing the implied fair value of goodwill. Since the implied fair value of goodwill was determined to be less than the carrying value, an impairment loss of approximately $4.4 million was recognized during the second quarter of 2014.
	2014 Annual Impairment Test
	For the 2014 annual impairment test for AQH and SCS, the Company estimated the fair value of each of the reporting units using a weighted average of 50% for the DCF approach and 50% for the EBITDA approach, which it determined to be the most representative allocation for the estimate of the long-term fair value of the reporting units. The AQH valuation assumed a taxable transaction while the SCS valuation assumed a non-taxable transaction, with WACC’s of 12.9% and 11.7%, respectively, and EBITDA multiples in the range of 7.0x to 7.5x and 7.5x to 9.0x, respectively, for the selected measurement periods of the latest twelve months through September 27, 2014, and forecasted 2014 and 2015. As the estimated fair values of AQH and SCS were both greater than their carrying value, no Step 2 test for goodwill impairment was required.
	The Company believes that its assumptions used to estimate the fair value of AQH and SCS as of the first day of the fourth quarter were reasonable. If different assumptions were used, particularly with respect to estimating future cash flows, weighted average costs of capital, and terminal growth rates, different estimates of fair value may have resulted. The estimated fair values of the AQH and SCS reporting units would have to decrease by approximately 48% and 46%, respectively, before a potential impairment would be recognized.
	The Company determined that it was appropriate to use the qualitative assessment approach for the 2014 annual goodwill impairment evaluation performed as of the first day of the fourth quarter for ERG and RCH. The estimated fair value of ERG derived in the Company's prior valuation analysis continued to be significantly in excess of the carrying value. The goodwill for RCH as of the first day of the fourth quarter represented the preliminary goodwill recorded in connection with the Company’s acquisition of Reznor (see Note 2, “Acquisitions”). Based on the qualitative analysis performed, as described above, the Company determined that it was more likely than not that the fair values of ERG and RCH were both greater than their carrying amounts as of the first day of the fourth quarter. Accordingly, the Company was not required to perform the two-step quantitative impairment test for 2014 for ERG and RCH.
	The Company did not prepare updated goodwill impairment analyses as of December 31, 2014 for any reporting unit, as there were no indicators during the quarter that would have required such analysis.
	2013 Goodwill Impairment Testing
	For the 2013 annual impairment test for AQH, ERG and legacy TECH, the Company estimated the fair value of each of the reporting units using a weighted average of 50% for the DCF approach and 50% for the EBITDA approach, which it determined to be the most representative allocation for the estimate of the long-term fair value of the reporting units. The AQH valuation assumed a taxable transaction while the ERG and the legacy TECH valuations each assumed a non-taxable transaction, with WACC’s of 13.2%, 13.4% and 14.5%, respectively, and EBITDA multiples in the range of 7.5x to 8.0x, 6.5x to 7.5x and 7.0x to 8.5x, respectively, for the selected measurement periods of the latest twelve months through September 30, 2013, and forecasted 2013 and 2014. As the estimated fair value of AQH, ERG and legacy TECH was greater than the carrying value, no Step 2 test for goodwill impairment was required. The Company did not prepare updated goodwill impairment analyses as of December 31, 2013 for any reporting unit, as there were no indicators during the quarter that would have required such analysis.
	The Company believes that its assumptions used to estimate the fair value of AQH, ERG and legacy TECH as of the first day of the fourth quarter were reasonable. If different assumptions were used, particularly with respect to estimating future cash flows, weighted average costs of capital, and terminal growth rates, different estimates of fair value may have resulted. The estimated fair values of the AQH, ERG, and legacy TECH reporting units would have to decrease by approximately 50.7%, 39.5%, and 23.8%, respectively, before a potential impairment would be recognized.
	2012 Goodwill Impairment Testing
	For the 2012 annual impairment test for AQH and ERG, the Company determined, based on the qualitative analysis performed , that it was more likely than not that the fair value of each of AQH and ERG was greater than their carrying amounts as of the first day of the fourth quarter. Accordingly, the Company was not required to perform the two-step impairment test as of that date with respect to these reporting units.
	For the 2012 annual impairment test for legacy TECH, the Company estimated the fair value of the reporting unit using a weighted average of 50% for the DCF approach and 50% for the EBITDA approach, which it determined to be the most representative allocation for the estimate of the long-term fair value of the reporting unit. The legacy TECH valuation assumed a taxable transaction, with a WACC of 16.9%, and EBITDA multiples in the range of 7.5x to 8.5x for the selected measurement periods of the latest twelve months through September 29, 2012, and forecasted 2012 and 2013. As the estimated fair value of legacy TECH was greater than the carrying value, no Step 2 test for goodwill impairment was required.

	Second Quarter 2014 Debt Transactions
	In connection with the acquisition of Reznor, on April 30, 2014, the Company entered into a new senior secured term loan facility due 2020 for $350.0 million (the "Term Loan Facility"). The net proceeds from the Term Loan Facility were used to acquire Reznor and to repay all of the outstanding secured debt under the Company's previously existing senior secured term loan due 2017, which had an aggregate principal amount outstanding of approximately $93.0 million upon repayment. The Company incurred fees and expenses of approximately $6.3 million, of which approximately $4.6 million has been included in deferred financing costs and are being recognized in accordance with the effective interest rate method. The redemption of the previously existing senior secured term loan facility resulted in a pre-tax loss of approximately $2.3 million in 2014.
	8.5% Senior Notes due 2021
	The 8.5% Senior Notes due 2021 (the "8.5% Notes") are unconditionally guaranteed on a senior unsecured basis by each of the Company's current and future domestic restricted subsidiaries (other than receivables subsidiaries, immaterial subsidiaries or non-wholly owned subsidiaries unless such non-wholly owned subsidiary guarantees any credit facilities or any capital market securities of the Company or any guarantor) that guarantee any of the Company's or other restricted subsidiaries' other indebtedness. Interest on the 8.5% Notes accrues at the rate of 8.5% per annum and is payable semi-annually in arrears on April 15 and October 15, until maturity. Interest on the 8.5% Notes accrues from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest is computed on the basis of a 360-day year comprised of twelve 30-day months.
	On or after April 15, 2016, the 8.5% Notes are redeemable at the option of the Company, in whole or in part, on or after April 15, 2016 at 104.25%, declining to 102.125% on April 15, 2017, declining to 101.063% on April 15, 2018 and further declining to 100.0% on April 15, 2019.
	In addition, at any time and from time to time prior to April 15, 2016, the Company may redeem all or any portion of the 8.5% Notes outstanding at a redemption price equal to (a) 100% of the aggregate principal amount of the 8.5% Notes to be redeemed together with accrued and unpaid interest to such redemption date, plus (b) the “Make Whole Amount”. The “Make Whole Amount” means, with respect to the 8.5% Notes at any redemption date, the greater of (i) 1.0% of the principal amount of the 8.5% Notes and (ii) the excess, if any, of (a) an amount equal to the present value of (1) the redemption price of the 8.5% Notes at April 15, 2016 plus (2) the remaining scheduled interest payments of the 8.5% Notes to be redeemed to April 15, 2016, computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (b) the principal amount of the 8.5% Notes to be redeemed.
	The indenture governing the 8.5% Notes contains certain restrictive financial and operating covenants including covenants that restrict, among other things, the payment of cash dividends, the incurrence of additional indebtedness, the making of certain investments, mergers, consolidations and the sale of assets (all as defined in the indenture and other agreements). At December 31, 2014, the Company's 10% Notes were the most restrictive. As of December 31, 2014, the Company was in compliance with all covenants under the indenture that governs the 8.5% Notes and believes it is reasonably assured that it will comply with the covenants for the foreseeable future.
	10% Senior Notes due 2018
	On November 23, 2010, the Company issued $250.0 million principal amount of 10% Senior Notes due December 1, 2018 (the "10% Notes”). The 10% Notes are unconditionally guaranteed on a senior unsecured basis by each of the Company's current and future domestic subsidiaries that guarantee its obligations under the ABL Facility. Net proceeds from the sale of the 10% Notes, after deducting underwriting commissions and expenses, amounted to approximately $243.2 million.
	Interest on the 10% Notes accrues at the rate of 10% per annum and is payable semi-annually in arrears on June 1 and December 1, until maturity. Interest on the 10% Notes accrues from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest is computed on the basis of a 360-day year comprised of twelve 30-day months.
	On or after December 1, 2014 the 10% Notes are redeemable at the option of the Company, in whole or in part, on or after December 1, 2014 at 105.0%, declining to 102.5% on December 1, 2015 and further declining to 100.0% on December 1, 2016.
	The indenture governing the 10% Notes contains certain restrictive financial and operating covenants including covenants that restrict, among other things, the payment of cash dividends, the incurrence of additional indebtedness, the making of certain investments, mergers, consolidations and the sale of assets (all as defined in the indenture and other agreements). As of December 31, 2014, the Company had the capacity to make certain payments, including dividends, under the 10% Notes of approximately $72.5 million. As of December 31, 2014, the Company was in compliance with all covenants under the indenture that governs the 10% Notes and believes it is reasonably assured that it will comply with the covenants for the foreseeable future.
	Term Loan and ABL Facilities
	The Term Loan Facility is repayable in quarterly installments of $875,000 with a balloon payment for the remaining balance due on October 30, 2020. Loans under the Term Loan Facility bear interest, at the Company's option, at a rate per annum equal to either (1) a Base Rate (as defined in the credit agreement governing the Term Loan Facility) or (2) a Eurodollar Rate (as defined in the credit agreement governing the Term Loan Facility), in each case plus an applicable margin. The interest rate related to the Term Loan Facility was approximately 3.75% at December 31, 2014.
	The Term Loan Facility provides that the Company may request additional tranches of term loans in an aggregate amount not to exceed $275.0 million and additional amounts subject to a secured leverage ratio condition. Availability of such additional tranches of term loans will be subject to the absence of any default, a pro forma secured leverage ratio test (in certain cases) and, among other things, the receipt of commitments by existing or additional financial institutions.
	The credit agreement governing the Company's Term Loan Facility requires the Company to prepay outstanding term loans, subject to certain exceptions, with:
	•	50% (subject to reduction to 25% and 0% based upon the Company's secured leverage ratio) of the Company's annual excess cash flow, commencing with the fiscal year ended December 31, 2015;
	•	100% of the net cash proceeds of certain asset sales and casualty and condemnation events, subject to reinvestment rights and certain other exceptions; and
	•	100% of the net cash proceeds of any issuance of debt, other than debt permitted under the Term Loan Facility.
	At December 31, 2014, there were no requirements to prepay outstanding amounts under the Term Loan Facility. The Company may voluntarily prepay outstanding loans at any time without premium or penalty other than customary “breakage” costs with respect to Eurodollar Rate loans.
	On June 13, 2012, the Company amended and extended its $300.0 million senior secured asset-based revolving credit facility (the “ABL Facility”). The amendment lowered the interest rates and fees payable by Nortek and extended the maturity from December 17, 2015 to June 13, 2017. Additionally, certain provisions of the credit agreement were amended to enhance Nortek's financial and operational flexibility. In conjunction with amending the ABL Facility in June 2012, the Company incurred fees and expenses of approximately $1.2 million which have been included in deferred financing costs and are being recognized over the remaining term of the ABL Facility.
	The ABL Facility consists of a $280.0 million U.S. facility (with a $60.0 million sublimit for the issuance of U.S. standby letters of credit and a $20.0 million sublimit for U.S. swingline loans) and a $20.0 million Canadian facility.
	There are limitations on the Company’s ability to incur the full $300.0 million of commitments under the ABL Facility. Availability is limited to the lesser of the borrowing base under the ABL Facility and $300.0 million. The borrowing base at any time will equal the sum (subject to certain reserves and other adjustments) of:
	•	85% of the net amount of eligible accounts receivable;
	•	85% of the net orderly liquidation value of eligible inventory; and
	•	available cash subject to certain limitations as specified in the ABL Facility.
	As of December 31, 2014, there were no outstanding borrowings and approximately $12.5 million in outstanding letters of credit under the ABL Facility. Based on the December 2014 borrowing base calculations, the Company had excess availability of approximately $287.5 million at December 31, 2014.
	The interest rates applicable to loans under the ABL Facility are, at the Company’s option, equal to either an adjusted LIBOR rate for a one, two, three or six month interest period (or such period of 365 days or less, if consented to by the relevant lenders) or an alternate base rate, plus an applicable margin percentage ranging from 1.75% to 2.25% for borrowings based on an adjusted LIBOR or Canadian bankers' acceptance rate, and 0.75% to 1.25% for borrowings based on a base or prime rate, depending on the Company’s Average Excess Availability (as defined in the ABL Facility). The alternate base rate, with respect to U.S. Borrowings, will be the greater of (1) the Federal Funds rate plus 0.50%, (2) 1.00% plus the LIBOR rate for a 30 day interest period as determined on such day, or (3) the prime rate. Interest is payable at the end of the selected interest period, but no less frequently than quarterly.
	The Company will be required to deposit cash daily from its material deposit accounts (including all concentration accounts) into collection accounts maintained with the administrative agent under the ABL Facility, which will be used to repay outstanding loans and cash collateralized letters of credit, if (i) excess availability (as defined in the ABL Facility) falls below the greater of $30.0 million or 12.5% of the borrowing base or (ii) an event of default has occurred and is continuing. Based on the December 2014 borrowing base calculations, the Company had approximately $250.0 million of excess availability before triggering the cash deposit requirements at December 31, 2014. In addition, under the ABL Facility, if (i) excess availability falls below the greater of $30.0 million or 12.5% of the borrowing base or (ii) an event of default has occurred and is continuing, the Company will be required to satisfy and maintain a consolidated fixed charge coverage ratio measured on a trailing four quarter basis of not less than 1.0 to 1.0. The Company’s ability to meet the required fixed charge coverage ratio can be affected by events beyond its control. A breach of any of these covenants could result in a default under the ABL Facility.
	Additional borrowings under the ABL Facility require the Company and its subsidiaries to make certain customary representations and warranties as of the date of such additional borrowing. In the event that the Company and its subsidiaries are unable to make such representations and warranties on such borrowing date, then the lenders under the ABL Facility may not honor such request for additional borrowing. The ABL Facility also provides the lenders considerable discretion to impose reserves or availability blocks, which could materially impair the amount of borrowings that would otherwise be available to the Company and its subsidiaries and may require the Company to repay certain amounts outstanding under the ABL Facility. There can be no assurance that the lenders under the ABL Facility will not impose such actions during the term of the ABL Facility.
	All obligations under the Company's Term Loan Facility and ABL Facility are unconditionally guaranteed by substantially all existing and future, direct and indirect, wholly-owned domestic (and, in the case of the ABL Facility, Canadian) restricted subsidiaries of the Company. All obligations under the Company's Term Loan Facility and ABL Facility, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the Company's assets and the assets of the guarantors, including:
	•	a second-priority security interest in the case of the Term Loan Facility, and a first-priority security interest in the case of the ABL Facility, in personal property consisting of accounts receivable, inventory, cash, deposit accounts, and certain related assets and proceeds of the foregoing; and
	•	a first-priority security interest in the case of the Term Loan Facility, and a second-priority interest in the case of the ABL Facility, in, and mortgages on, substantially all of the Company's material owned real property and equipment and in the case of the Term Loan Facility, a pledge of the capital stock of any direct subsidiaries held by guarantor (limited for certain foreign subsidiaries to 65% of the voting capital of first-tier foreign subsidiaries).
	The Term Loan Facility and ABL Facility agreements contains certain restrictive financial and operating covenants, including covenants that restrict the Company's ability and the ability of its subsidiaries to complete acquisitions, pay dividends, incur indebtedness or liens, make investments, sell assets and take certain other corporate actions. As of December 31, 2014, the Company was in compliance with all covenants under the agreements that govern the Term Loan Facility and the ABL Facility and believes it is reasonably assured that it will comply with the covenants for the foreseeable future.
	Other Indebtedness
	Mortgage notes payable of approximately $1.3 million outstanding at December 31, 2014 includes various mortgage notes and other related indebtedness payable in installments through 2019. These notes have a weighted average interest rate of approximately 2.7% and are collateralized by property and equipment with an aggregate net book value of approximately $3.7 million at December 31, 2014.
Other obligations, including capital leases, of approximately $8.0 million outstanding at December 31, 2014 include borrowings relating to equipment purchases, notes payable issued for acquisitions and other borrowings bearing interest at rates ranging from approximately 5.8% to 12.2% and maturing at various dates through 2020. Approximately $4.6 million of such indebtedness is collateralized by property and equipment with an aggregate net book value of approximately $12.3 million at December 31, 2014.
Fourth Quarter 2012 Debt Transaction
On October 18, 2012, the Company issued $235.0 million aggregate principal amount of 8.5% Senior Notes due 2021 (the "New 8.5% Notes") which were offered as additional notes under the indenture pursuant to which the Company previously issued $500.0 million aggregate principal amount of 8.5% Senior Notes due 2021.
The Company received approximately $251.7 million of gross proceeds in connection with the issuance of these notes, which were used to pay down an equal amount of aggregate principal of the Company's previously existing senior secured term loan due 2017. The Company used cash on hand to pay accrued interest of approximately $1.8 million related to the previously existing senior secured term loan due 2017 and to pay underwriting, legal, and accounting fees of approximately $4.7 million related to the issuance of the New 8.5% Notes.
Certain holders of the New 8.5% Notes had previously held loans under the Company's previously existing senior secured term loan due 2017 up to the time they were paid down. In accordance with ASC 470-50, "Debt Modifications and Extinguishments" (“ASC 470-50”), the Company determined that of the net total of the related previously existing senior secured term loan due 2017 original issue discounts, New 8.5% Note premiums, underwriting commissions, legal, accounting and other expenses, approximately $6.4 million should be recorded as a loss on debt retirement, and approximately $3.9 million and $15.1 million should be recorded as deferred debt expense and debt premium, respectively, and amortized over the life of the New 8.5% Notes.
Scheduled Maturities
At December 31, 2014, the maturities for the Company’s notes, mortgage notes and obligations payable (excluding approximately $4.8 million of unamortized debt premium and approximately $1.9 million of unamortized debt discount) were:

	Warehousing and Distribution Consolidation
	In connection with the Company's efforts to optimize supply chain performance, the Company's Board of Directors have also approved entry into a five-year agreement with a third party logistics service provider to outsource certain warehousing and distribution activities in the Company's North American operating segments and facilitate the consolidation of North American warehousing distribution centers (the "Warehousing & Distribution Consolidation"). The Company expects these initiatives to generate cost savings as a result of moving to shared distribution centers and leveraging its scale by optimizing shipments and consolidating facilities.
	The Company has substantially completed the Warehousing & Distribution Consolidation and has incurred cumulative severance and other costs of approximately $3.0 million, of which approximately $2.0 million, $0.6 million, and $0.4 million were recorded in the SCS, ERG, and combined AVC segments, respectively.

	Subsidiary Combinations
	The Company has combined, or is in the process of combining, the operations of certain subsidiaries in order to improve overall operational efficiencies, reduce costs, and provide potential for greater revenue growth ("Subsidiary Combinations").  The total expected costs related to one time termination benefits and other costs associated with Subsidiary Combinations are estimated to be approximately $17.8 million to $18.3 million. Total expected costs by segment are as follows:
			Low			High
			(Dollar amounts in millions)

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES
	Lease Obligations
	At December 31, 2014
	, the Company is obligated under operating lease agreements for the rental of certain real estate and machinery and equipment used in its operations. At December 31, 2014, future minimum rental obligations aggregated approximately $88.0 million and are payable as follows:
	Year Ended December 31,	Future Minimum Rental Obligations
		(Dollar amounts in millions)
	2015	$	21.6
	2016	17.2
	2017	13.8
	2018	10.4
	2019	8.5
	Thereafter	16.5
	Certain of these lease agreements provide for increased payments based on changes in the consumer price index. Under certain of these lease agreements, the Company or its subsidiaries are also obligated to pay insurance and taxes. Certain of the Company’s operating lease arrangements for the rental of real estate contain renewal options.  The Company has reviewed the provisions of the renewal options and determined that none of the renewal options represent bargain renewal options.  In addition, certain of the Company's operating lease arrangements for the rental of real estate contain certain restrictions, including restrictions on use and sublease of the leased properties.  The Company has evaluated the restrictions and determined that none of the restrictions limit its ability to utilize the property for its intended purpose. At December 31, 2014, the Company is obligated under operating lease agreements for the rental of certain real estate with lease terms ranging from 1 year to 29 years and machinery and equipment used in its operations with lease terms ranging from 2 years to 5.5 years.
	Rental expense charged to continuing operations in the accompanying consolidated statements of operations was approximately $29.9 million, $32.7 million and $34.3 million for 2014, 2013 and 2012, respectively.
	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 in the accompanying unaudited condensed consolidated balance sheet as follows:
			For the year ended December 31,
			2014			2013
			(Dollar amounts in millions)
	Accrued expenses		$	2.5		$	2.4
	Other long-term liabilities		2.4			2.7
			$	4.9		$	5.1
	Undiscounted future payments		$	5.1		$	5.4
	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.  Warranty costs are included in cost of products sold. 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 2014 and 2013 are as follows:
			December 31,
			2014			2013
			(Dollar amounts in millions)
	Balance, beginning of period		$	56.8		$	54.7
	Warranties provided during period (1)		26.6			30.8
	Settlements made during period		(31.5		)	(30.5		)
	Changes in liability estimate, including		2.9			1.8
	expirations and acquisitions
	Balance, end of period		$	54.8		$	56.8
	-1	For 2013, includes additional warranties provided within the SCS segment of approximately $3.4 million related to a product safety recall and other warranty matters and additional warranties of approximately $6.5 million within the CAS segment related to a certain warranty matter.
	The Company has undertaken several voluntary product recalls and reworks over the past several years and could do so in the future given the nature of the Company's business. Additional product recalls and reworks could result in material future costs. Many of the Company's products, especially certain models of bath fans, range hoods, and residential furnaces and air conditioners, have a large installed base, and any recalls or reworks related to such products could be particularly costly. The costs of product recalls or reworks are not generally covered by insurance. Recalls or reworks may adversely affect the Company's reputation as a manufacturer of high-quality, safe products and could have a material adverse effect on its financial condition, results of operations and cash flows.
	Purchase Obligations
	The Company has certain non-cancelable purchase obligations, which principally relate to the purchase of raw materials and components that are utilized in the Company’s products, as well as certain commitments for capital expenditures.  These purchase obligations are generally less than one year and as of December 31, 2014 totaled approximately $26.8 million.  There were no material purchase obligations in excess of quantities expected to be utilized in normal operations.
	Other Commitments and Contingencies
	During 2014, the Company completed construction and placed into service approximately $24.5 million and $7.0 million of buildings related to facilities in Mexico for the RCH and CAS segments, respectively. In accordance with the provisions of ASC 840, Leases, the Company was considered to be the owner of the asset during the construction period and the Company determined that the facilities did not qualify for de-recognition upon completion. These buildings are being depreciated over a 20 year estimated remaining useful life. The corresponding present values of the liabilities for the minimum monthly payments for these facilities are included in accrued liabilities for the current portion and other long-term liabilities for the long-term portion and are being amortized over 20 years using interest rates of approximately 7.5% and 6.4% for the RCH and CAS obligations, respectively. Annual minimum payments under these agreements are approximately $2.4 million and $0.6 million for the RCH and CAS obligations, respectively.
	For reasons of quality assurance, scarcity or cost effectiveness, certain components and raw materials used in the manufacture of the Company’s products are available only from a limited number of suppliers. In the event that the Company is unable to obtain sufficient quantities of raw materials or components on commercially reasonable terms or in a timely manner, the Company’s ability to manufacture its products on a timely and cost-competitive basis may be compromised, which may have a material adverse effect on its business, financial condition and results of operations. To date, the Company has not experienced any material adverse effect on its financial condition or results of operations due to supplier limitations.
	As previously reported, as part of the Company's routine internal audit activities, it discovered certain questionable hospitality, gift and payment practices, and other expenses at the Company’s subsidiary, Linear Electronics (Shenzhen) Co. Ltd. (“Linear China”), which are inconsistent with the Company’s policies and raise concerns under the U.S. Foreign Corrupt Practices Act and perhaps under other applicable anti-corruption laws. The Company initiated an internal investigation into these practices and payments with the assistance of outside counsel.
	On January 7, 2015 and January 8, 2015, respectively, the Company voluntarily contacted the SEC and the DOJ to advise both agencies of the Company's internal investigation. The Company intends to cooperate with any SEC or DOJ investigation into these matters. The Company takes these matters very seriously and is committed to conducting its business in compliance with all applicable laws.
	Based on information known at this time, the Company currently believes that the amount of the questionable expenses and payments is not material with respect to the Company’s financial condition or results of operations. However, at this time, the Company is unable to predict, what, if any, action may be taken by the DOJ or SEC or any penalties or remedial measures these agencies may seek, but intends to cooperate with both agencies. Any determination that the Company's operations or activities are not in compliance with existing laws or regulations could result in the imposition of fines, civil and criminal penalties, and equitable remedies, including disgorgement or injunctive relief. The Company cannot reasonably estimate the potential liability, if any, related to these matters resulting from any proceedings that may be commenced by the SEC, the DOJ or any other governmental authorities. Accordingly, no provision with respect to such matters has been recorded in the accompanying consolidated financial statements. For the year ended December 31, 2014, approximately $0.8 million was recorded for legal and other professional services incurred related to the internal investigation of this matter. The Company expects to incur additional costs relating to the investigation of this matter in 2015.
	Product Liability Contingencies
	Nortek Global HVAC LLC ("Nordyne"), our wholly owned subsidiary, is the defendant in a putative class action lawsuit in Florida, Harris, et al. v. Nordyne, LLC, Case No. 1:14-cv-21884-BB, filed in the United States District Court for the Southern District of Florida.  In addition, Nortek, Inc., Nortek Global HVAC LLC and Nortek Global HVAC Latin America, Inc. are the defendants in a putative class action lawsuit in Tennessee, Bauer, et al. v. Nordyne, LLC et al., Case No. 3:14-cv-01940, filed in the United States District Court for the Middle District of Tennessee.  These lawsuits allege that evaporator and condenser coils in Nordyne’s residential heating and cooling products are susceptible to a type of potential corrosion of the copper tubing in the units that can result in coil leaks and/or failure of the units.  The Florida action was initiated on May 21, 2014 and seeks compensatory damages associated with Nordyne’s alleged wrongdoing, injunctive relief, and attorneys’ fees and costs.  The Tennessee action was initiated on October 3, 2014 and seeks damages associated with repairing, retrofitting and/or replacing the allegedly defective products, the loss of value due to the alleged defect, property damages associated with the alleged defect, injunctive relief, punitive damages, and attorneys’ fees and costs. No arguments or ruling with respect to class action status have occurred to date in either of these actions.  While these actions are in their initial stages, the Company believes it has meritorious defenses against these complaints.  At this time, the Company believes that the likelihood of a material loss in such matters is remote and has not recognized a loss or liability in these actions; however, it is possible that events could occur that would change the likelihood of a material loss, which could ultimately have a material impact on our business.  The Company will continue to assess the likelihood of a material loss as the actions progress.
	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.

	The Company has recorded approximately $3.2 million of realized tax benefits related to deductions for share-based compensation in excess of the corresponding book expense to additional paid in capital in 2014. The Company has approximately $4.6 million of remaining excess tax benefits that will be recognized as a credit to additional paid in capital when the benefits are realized on a tax return.  The Company accounts for share-based compensation deductions on the basis that these are the last tax benefits that are utilized. The Company also recorded a benefit to other comprehensive income of approximately $4.6 million related to deferred income taxes on pension liability (Note 13, “Pension, Profit Sharing and Other Post-Retirement Benefits”).
	Income tax payments, net of refunds, for 2014, 2013 and 2012 were approximately $14.4 million, $12.2 million and $5.9 million, respectively.

		$	(211.3	)	$	(242.4	)
	Net Deferred Tax Liabilities	$	(95.4	)	$	(129.4	)
	The above are reflected in the Company's consolidated balance sheet as short-term deferred tax assets of approximately $28.1 million and $29.7 million at December 31, 2014 and 2013, respectively, and long-term deferred tax liabilities of approximately $123.5 million and $159.1 million at December 31, 2014 and 2013, respectively.
The Company has assessed the realizability of its deferred tax assets. The Company has sufficient reversing deferred tax liabilities available so that it is more likely than not that its federal deferred tax assets will be realized. The Company continues to maintain a valuation allowance for certain foreign net operating loss carryforwards, state net operating loss carryforwards, deferred state tax assets and for certain federal deferred tax assets that, if recognized, would result in capital losses. The increase in valuation allowance for 2014 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, and expectations for the future, 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.
At December 31, 2014, the Company has not provided United States income taxes or foreign withholding taxes on unremitted foreign earnings of approximately $66.2 million, as those amounts are considered indefinitely invested. Due to the complexities of the U.S. tax law, including the effect of U.S. foreign tax credits, it is not practicable to estimate the amount of tax that might be payable on these earnings in the event they no longer are indefinitely reinvested. The Company has provided United States income taxes and foreign withholding taxes on approximately $5.0 million of unremitted foreign earnings which are not indefinitely invested.
The Company has state net operating losses with a tax effect of approximately $20.2 million in various jurisdictions which will begin to expire in 2015.
The Company has approximately $113.3 million of foreign net operating loss carry-forwards that, if utilized, would offset future foreign tax payments. Approximately $107.0 million of these foreign net operating losses have an indefinite carry-forward period and the remaining foreign net operating losses will expire at various times beginning in 2017. The Company has recorded a full valuation allowance against these losses.
A reconciliation of the beginning and ending amounts of unrecognized tax benefits for the years ended December 31, 2014 and 2013 is as follows:
	December 31,
	2014			2013
	(Dollar amounts in millions)
Balance at January 1,	$	30.7		$	32.6
Gross increases related to positions taken in the current year	2.2			3.9
Gross increases related to positions taken in prior periods	1.4			1.6
Increases related to acquisitions	—			0.2
Decreases related to settlements with taxing authorities	(0.8		)	(2.3		)
Decreases due to lapse of statutes of limitation related to state tax and foreign items	(3.3		)	(4.1		)
Decreases related to positions taken in the current year	(6.0		)	$	(1.2	)
Balance at December 31,	$	24.2		$	30.7
As of January 1, 2014, the Company had a liability of approximately $20.8 million for unrecognized tax benefits related to various federal, foreign and state income tax matters.  The liability for unrecognized tax benefits at December 31, 2014 was approximately $18.3 million. The liability for unrecognized tax benefits is included in other long-term liabilities on the accompanying consolidated balance sheet. The corresponding amount of gross unrecognized tax benefits was approximately $24.2 million and $30.7 million at December 31, 2014 and 2013, respectively. The difference between the total unrecognized tax benefits and the amount of the liability for unrecognized tax benefits represents unrecognized tax benefits that have been netted against deferred tax assets in accordance with ASU No. 2013-11.
During 2014, the Company decreased the reserve for unrecognized tax benefits related to uncertainties surrounding the timing of deductions related to intercompany transactions with foreign affiliates. This item resulted in a decrease of approximately $5.7 million in the liability for unrecognized tax benefits, with a corresponding decrease in deferred tax assets of approximately $5.7 million.
During 2014, the Company recorded a liability for unrecognized tax benefits in connection with an ongoing tax matter involving a foreign subsidiary. The Company recorded a gross reserve of approximately $1.3 million, and related accrued interest of approximately $1.2 million. The Company also recorded a corresponding deferred tax asset related to the U.S. tax deduction for these items of approximately $0.9 million. The total amount provided for this item was approximately $1.6 million.
During 2014, the Company also reversed approximately $3.3 million in uncertain tax positions related to the expiration of the statute of limitations.  This amount was offset by a corresponding reversal of an offsetting related tax asset of approximately $1.4 million.
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.
During the fourth quarter of 2013, the Company recorded a benefit of approximately $2.1 million related to the expiration of the statute of limitations in connection with unrecognized tax benefits that related to periods prior to the acquisition of Ergotron. This unrecognized tax benefit was subject to an indemnification claim from the seller. As a result, the corresponding indemnification asset was written-off as part of SG&A in the fourth quarter of 2013.
As of December 31, 2014 and 2013, the amount of unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate is approximately $11.3 million and $10.9 million, respectively. The difference between the total amount of uncertain tax positions and the amount that would affect the effective tax rate represents the federal tax effect of state tax items, items that offset temporary differences, and items that will result in a reduction of other tax assets.
As of December 31, 2014, the Company had approximately $0.8 million in unrecognized benefits relating to various tax issues, for which the statute of limitations is expected to expire in 2015.
As of December 31, 2014 and 2013, the total amount of accrued interest and penalties related to uncertain tax positions was approximately $4.1 million and $4.0 million, respectively.  In 2014, the Company has recorded a provision of approximately $0.3 million as part of its 2014 tax provision related to a net reduction in interest on uncertain tax positions. The Company has included a benefit of approximately $0.3 million as part of its 2013 tax provision related to a net reduction in interest on uncertain tax positions. The Company has included a provision of approximately $0.5 million as part of its 2012 tax provision related to an increase of interest on uncertain tax positions. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for federal and state taxes.
The Company's consolidated federal tax return has been audited through the period ended December 31, 2009. The Company's state and foreign tax filings generally remain open to examination by the relevant tax authority for the tax years 2010 through 2014. One of the Company's foreign subsidiaries is currently under audit for the years 2007 - 2012. In connection with this audit, the Company has recorded a liability of approximately $0.8 million for potential income tax liabilities and approximately $0.7 million for additional VAT liabilities. The Company has reached a settlement related to income tax issues in these audit years, which is consistent with the reserves that were recorded.

SEGMENT INFORMATION AND CONCENTRATION OF CREDIT RISK	12 Months Ended
	Dec. 31, 2014
Segment Reporting [Abstract]
SEGMENT INFORMATION AND CONCENTRATION OF CREDIT RISK	SEGMENT INFORMATION AND CONCENTRATION OF CREDIT RISK
	The Company's five principal reporting segments are as follows:
	•	the Air Quality and Home Solutions, formerly Residential Ventilation (“RESV”), segment,
	•	the Security and Control Solutions, formerly Technology Solutions (“TECH”), segment,
	•	the Ergonomic and Productivity Solutions, formerly Display Mount Solutions ("DMS"), segment,
	•	the Residential and Commercial HVAC, formerly Residential Heating and Cooling (“RHC”), segment, and
	•	the Custom and Commercial Air Solutions, formerly Custom & Engineered Solutions (“CES”), segment.
	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 AQH segment primarily manufactures and distributes room and whole house ventilation products for the professional remodeling and replacement markets, residential new construction market, and do-it-yourself market. The principal products sold by this segment include kitchen range hoods, exhaust fans (such as bath fans and fan, heater and light combination units), and indoor air quality products (such as air exchangers and heat energy recovery ventilators).   Sales of the Company’s kitchen range hoods and exhaust fans within the AQH segment accounted for approximately 9.6% and 9.1%, respectively, of consolidated net sales for 2014, approximately 10.7% and 9.8%, respectively, of consolidated net sales in 2013 and approximately 11.6% and 10.0%, respectively, of consolidated net sales in 2012.
	The SCS segment manufactures and distributes a broad array of products designed to provide convenience and security primarily for residential applications. The principal product categories in this segment include security, automation and access control equipment and systems. Sales of security systems and components with the SCS segment accounted for approximately 12.8% and 10.1% of consolidated net sales for 2014 and 2013, respectively. During 2012, sales of security systems and components accounted for less than 10% of consolidated net sales.
	The ERG segment manufactures and distributes a broad array of innovative products designed with ergonomic features including wall mounts, carts, arms, desk mounts, workstations, and stands that attach to or support a variety of display devices such as notebook computers, computer monitors, and flat panel displays. Sales of the Company's digital display mounting and mobility products within the ERG segment accounted for approximately 11.6%, 12.0% and 12.9% of consolidated net sales in 2014, 2013 and 2012, respectively.
	The RCH segment principally manufactures and sells split-system and packaged air conditioners and heat pumps, furnaces, air handlers and parts for the residential replacement and new construction markets. In addition, this segment produces unit heaters, radiant heaters and rooftop heating, ventilation and cooling products primarily for industrial and commercial applications. Sales of products sold in the RCH segment accounted for approximately 22.3%, 18.1% and 17.3% of consolidated net sales in 2014, 2013 and 2012, respectively.
	The CAS segment manufactures and sells custom-designed and engineered HVAC products and systems, primarily in North America, for non-residential applications. The principal products sold by the segment are air handlers and large custom rooftop cooling and heating products. Sales of the Company’s commercial air handlers within the CAS segment accounted for approximately 14.5%, 15.4% and 14.6% of consolidated net sales in 2014, 2013 and 2012, respectively.
	The AVC segments manufacture and distribute a broad array of products primarily for the residential audio/video and professional video signal management markets. The principal product categories in these segments include residential audio/video equipment (including architectural speakers and power conditioners, among other products), home control equipment, and professional video signal management solutions.
	No other single product class accounts for 10% or more of consolidated net sales.
	The accounting policies of the segments are the same as those described in Note 1, “Summary of Significant Accounting Policies”. The Company evaluates segment performance based on operating earnings before allocations of corporate overhead costs and impairment charges. With the exception of intersegment net sales between the SCS segment and the AVC segments, intersegment net sales and intersegment eliminations are not material for any of the periods presented. The financial statement impact of all acquisition accounting adjustments, including intangible asset amortization and goodwill, are reflected in the applicable operating segment, which are the Company’s reporting units. Unallocated assets consist primarily of cash and cash equivalents, marketable securities, prepaid and deferred income taxes, deferred debt expense and long-term restricted investments and marketable securities.
	Net sales, operating earnings (loss) and (loss) earnings before (benefit) provision for income taxes for the Company’s reporting segments for the three years ended December 31, 2014 were as follows:

Foreign net sales were approximately 16.5%, 16.5%, and 18.7% of consolidated net sales for 2014, 2013, and 2012, respectively. Foreign net sales are attributed based on the location of the Company’s subsidiary responsible for the sale. Excluding financial instruments and deferred income taxes, foreign long-lived assets were approximately 11.8% and 9.3% of consolidated long-lived assets at December 31, 2014 and 2013, respectively.
The Company operates internationally and is exposed to market risks from changes in foreign exchange rates. Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporary cash investments and trade receivables. The Company places its temporary cash investments with high credit quality financial institutions and limits the amount of credit exposure to any one financial institution. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising the Company’s customer base and their dispersion across many different geographical regions. These risks are not significantly dissimilar among the Company’s five reporting segments. Accounts receivable from customers related to foreign operations at December 31, 2014 and 2013 was approximately 20.0% and 20.0% of consolidated accounts receivable, respectively.
No single customer accounts for 10% or more of consolidated net sales or accounts receivable.

	Basic earnings (loss) per share amounts are computed using the weighted average number of common shares outstanding during the period.  Diluted earnings (loss) per share amounts are computed using the weighted average number of common shares outstanding and dilutive potential common shares outstanding during each period.
	The reconciliations between basic and diluted (loss) earnings per share for the three years ended December 31, 2014 are as follows:
		For the year ended December 31,

	The effect of certain potential common share equivalents, as outlined below, were excluded from the computation of diluted shares outstanding for 2014, 2013 and 2012 as their inclusion would have been anti-dilutive. Restricted stock awards which vest based upon achievement of performance targets were excluded from the diluted shares outstanding as the performance targets had not been met as of the end of 2014, 2013 and 2012.
	In reporting periods in which the Company reports a net loss, anti-dilutive shares consist of the weighted average common stock equivalents outstanding for the period. In those reporting periods in which the Company reports net income, anti-dilutive shares consist of those common stock equivalents that have either an exercise price above the average stock price for the period or the common stock equivalents’ related average unrecognized stock compensation expense is sufficient to “buy back” the entire amount of shares.
	A summary of the weighted average anti-dilutive shares excluded from each of the three years ended December 31, 2014 is as follows:

	Incentive Compensation Plan
	On December 17, 2009, the Company established the 2009 Omnibus Incentive Plan (the “Incentive Plan”) which allows for grants of options, stock appreciation rights, restricted stock, other stock-based awards and performance-based compensation awards. The Incentive Plan is administered by the Board of Directors, the Compensation Committee of the Board of Directors, or any other committee designated by the Board of Directors to administer the Incentive Plan (the “Committee”). Participants consist of such employees, directors and other individuals providing services to the Company, or any subsidiary or affiliate, as the Committee in its sole discretion determines and whom the Committee may designate from time to time to receive awards.
	Under the 2009 Plan, 2,885,907 shares were authorized for grant through December 17, 2019, of which 1,076,555 may be in the form of incentive stock options. The maximum number of shares for which options and stock appreciation rights may be granted to any participant in any calendar year is 627,990, and the maximum number of shares with respect to other awards denominated in shares in any calendar year is 627,990. The maximum value of cash payable with respect to awards denominated in cash or property that may be granted to any participant in any plan year is $5.0 million, subject to certain adjustments as defined. In the event that any outstanding award expires, is forfeited, canceled or otherwise terminated without the issuance of shares or is otherwise settled for cash, the shares subject to such award shall again be available for awards. At December 31, 2014, there are 1,148,218 remaining shares available for grant under the Incentive Plan.
	Stock Options
	The Company has awarded options with time based vesting to certain key employees. These options vest annually, on the anniversary of the date of grant, over three or five years provided the recipient remains employed by the Company. All options expire on the tenth anniversary of the grant date, unless terminated earlier.
	The following table summarizes the Company's common stock option transactions for the three years ended December 31, 2014.

	Remaining options expected to vest as of December 31, 2014		215,337			$	49.28	7.8		$	6.9		(1)
	-1	The aggregate intrinsic value of options represents the total pre-tax intrinsic value (the difference between the estimated fair value of the Company's stock on December 31, 2014 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2014. This amount changes based upon the fair market value of the Company's common stock.
	The weighted average grant date fair value of options granted was approximately $29.92, $28.27 and $17.66 during the years ended December 31, 2014, 2013 and 2012, respectively.
	The estimated fair value of the options granted was measured on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions:
			December 31,
			2014		2013		2012
	Risk-Free Interest Rate		1.59%		0.77%		1.16%
	Expected Term		6.0 years		6.0 years		6.60 years
	Expected Volatility		40.00%		40.00%		40.00%
	Expected Dividend Yield		—%		—%		—%
	The risk-free interest rate for periods within the life of the option is based upon a blend of U.S. Treasury bond rates with maturities equal to the expected term of the options. The expected term assumption was derived using the simplified method, as described in SEC Staff Accounting Bulletin Topic 14.D.2, "Share-Based Payment - Certain Assumptions Used in Valuation Methods". The expected volatility assumption is based upon the historical volatility of comparable public companies’ stock as well as the implied volatility of outstanding options for the comparable companies that had such options. The dividend yield represents the expected dividends on the Company's common stock for the expected term of the option.
	The amount of stock-based compensation expense recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based on an analysis of historical forfeitures, we have determined a specific forfeiture rate for certain employee groups based on the award date and have applied forfeiture rates ranging from approximately 0% to 26% at December 31, 2014 depending on the specific employee group. This analysis is re-evaluated periodically and the forfeiture rate is adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those awards that vest.
	As of December 31, 2014, there was approximately $3.2 million of unrecognized compensation cost related to stock options granted under the Incentive Plan. This cost is expected to be recognized on a straight-line basis over a weighted average period of approximately 1.7 years. Total compensation expense related to stock options was approximately $2.3 million, $2.2 million and $1.3 million for the three years ended December 31, 2014, 2013 and 2012, respectively. The related tax benefit recognized for 2014, 2013 and 2012 totaled approximately $0.9 million, $0.8 million and $0.3 million, respectively.
	Restricted Stock
	The Company has awarded performance based restricted shares of common stock to certain key employees. These shares are eligible to become vested in annual installments and, in some cases cumulatively, based upon the achievement of specified levels of Adjusted EBITDA, as defined, for each year. The shares, if any, are vested as of December 31 of each year. However, as the number of shares vesting is contingent upon the Company's financial results, determined based upon the issuance of audited financial statements, the actual issuance of shares to recipients does not occur until the first quarter of the following year.
	The Company has also awarded time-based restricted shares of common stock to certain key employees. These shares vest annually, on the anniversary of the date of grant, over three or five years provided the recipient remains employed by the Company.
	Restricted stock has the same cash dividend and voting rights as other common stock and, once issued, is considered to be legally issued and outstanding (even when unvested). Recipients of restricted stock are entitled to dividends when and if the Company pays a cash dividend on its common stock. Such dividends are not payable to the recipient until the vesting of the related restricted shares.
	The following table summarizes the Company's restricted stock activity for the three years ended December 31, 2014:
			Time-Based					Performance-Based
			Number of			Weighted Average		Number of			Weighted Average
			Shares			Grant Date		Shares			Grant Date
						Fair Value					Fair Value
	Unvested, December 31, 2011		100,616			$	28.7	266,236			$	11.29

	Unvested, December 31, 2014		105,666			$	61.24	240,939			$	66.8
	The aggregate fair value of shares vested calculated as of the vesting date during the years ended December 31, 2014, 2013 and 2012 was approximately $4.8 million, $12.1 million and $4.6 million, respectively.
	The cost of the performance based restricted stock awards, calculated as the estimated grant date fair value, net of estimated forfeitures, is recognized over the remaining service period if it is probable that the restricted shares, or any portion thereof, will vest. The cost of the time-based restricted stock awards, net of estimated forfeitures, is being recognized on a straight-line basis over the related vesting period. The estimated fair value of the grants is based upon the closing price of the Company's stock on the date of grant. Total compensation expense recognized for the years ended December 31, 2014, 2013 and 2012 related to restricted stock was approximately $3.9 million, $8.3 million and $3.3 million, respectively. The related tax benefit recognized for the years ended December 31, 2014, 2013 and 2012 totaled approximately $1.5 million, $3.2 million and $1.3 million, respectively.
	For non-vested restricted stock subject to time-based vesting conditions outstanding as of December 31, 2014, the Company had approximately $4.2 million of unrecognized stock-based compensation expense, which is expected to be recognized over a weighted average period of approximately 1.9 years. For non-vested restricted stock subject to performance-based vesting conditions outstanding and that were probable of vesting as of December 31, 2014, the Company had approximately $2.7 million of unrecognized stock-based compensation expense, which is expected to be recognized over a weighted average period of approximately 1.9 years. For non-vested restricted stock subject to performance-based vesting conditions outstanding that were not probable of vesting as of December 31, 2014, the Company had approximately $9.5 million of unrecognized stock-based compensation expense. If and when any additional portion of these awards are deemed probable to vest, the Company will reflect the effect of the change in estimate in the period of change by recording a cumulative catch-up adjustment to retroactively apply the new estimate.

Compensation and Retirement Disclosure [Abstract]
PENSION, PROFIT SHARING AND OTHER POST-RETIREMENT BENEFITS	PENSION, PROFIT SHARING AND OTHER POST-RETIREMENT BENEFITS
	Nortek and its subsidiaries have various pension plans, supplemental retirement plans for certain officers, profit sharing, and other post-retirement benefit plans requiring contributions to qualified trusts and union administered funds.
	The Company's pension plans offer subsidized early retirement and lump sum payments. The Company's actuaries use assumptions to capture the value of these forms of payments within the liability calculation.
	The Company's policy is to generally fund currently at least the minimum required annual contribution of its various qualified defined benefit plans. At December 31, 2014, the Company expects to contribute approximately $7.9 million to its defined benefit pension plans in 2015.
	Impact on Financial Statements
	Pension, profit sharing, 401(k) match contributions, and other post-retirement health benefit expense charged to operations aggregated approximately $9.4 million, $7.7 million and $7.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. The increase in pension, profit sharing and other post-retirement health benefit expense for 2014 as compared to 2013 is due primarily to increases in the company matched contribution on 401(k) plans and increases in profit sharing accruals at certain of the Company's subsidiaries. This increase was partially offset by a decrease in the defined benefit plan expense attributable to a reduction in the required recognition of the cumulative unrecognized loss. Favorable investment return and an increase in the discount rate combined to both improve the funded status and reduce the outstanding loss.
	The increase in pension, profit sharing and other post-retirement health benefit expense for 2013 as compared to 2012 is primarily attributable to a net increase in profit sharing expense, partially offset by a reduction in interest cost resulting from lower discount rates for the companies' defined benefit plans tempered by a reduction in the plan’s expected return on assets and a slightly higher required recognition of the cumulative loss.
	The Company’s net periodic benefit cost (income) for its defined benefit and post-retirement health benefit plans for the years ended December 31, 2014, 2013 and 2012 consists of the following components:
			For the year ended December 31,
			2014								2013							2012
			Defined Benefit				Post- Retirement Health Benefits				Defined Benefit				Post- Retirement Health Benefits			Defined Benefit			Post- Retirement Health Benefits

	Net periodic benefit cost (income)		$	0.7			$	—			$	1.3			$	—		$	1.7		$	(0.3	)
	The Company's net periodic benefit cost for its post-retirement health benefit plans reflects settlement accounting resulting from the final payouts of certain participants in the plan during 2012.
	Amortization of unrecognized net gain or loss resulting from experience different from that assumed and from changes in assumptions is included as a component of net period benefit cost, if as of the beginning of the year, the unrecognized net gain or loss exceeds 10% of the projected benefit obligation.  If amortization is required, the amount recognized is the excess divided by the average remaining service period of active employees expected to receive benefits under the plan.  In cases where almost all of the participants are inactive, average life expectancy is utilized instead of average remaining service.  For the qualified plans, the Company uses average future lifetime as the amortization period.
	The following table outlines the rollforward of the benefit obligation and plan assets for the defined benefit and post-retirement health benefit plans for the years ended December 31, 2014 and 2013:

	The adjustment to accumulated other comprehensive income represents the net unrecognized actuarial gains and losses. At December 31, 2014, 2013 and 2012, the net actuarial loss recognized within accumulated other comprehensive loss that has not yet been recognized as a component of net periodic pension cost, net of tax, was approximately $26.9 million, $15.4 million and $24.4 million, respectively, which includes the defined benefit and post-retirement health benefit plans. The Company expects to recognize approximately $1.1 million in accumulated other comprehensive income as components of net periodic benefit cost in the year ended December 31, 2015 for its defined benefit plans and an immaterial amount for its post-retirement health benefit plans.
	Information for the Company's defined benefit plans with accumulated benefit obligations in excess of plan assets as of December 31, 2014 and 2013 is as follows:

The Company’s domestic qualified defined benefit plans’ and foreign pension plan’s assets are invested to maximize returns without undue exposure to risk. The domestic plans' investment objectives are to produce a total return exceeding the median of a universe of portfolios with similar average asset allocation and investment style objectives, and to earn a return, net of fees, greater or equal to the long-term rate of return used by the Company in determining pension expense. The foreign plan investment objectives for the fixed income pooled pension fund are to provide capital growth and income primarily through investment in non-government debt securities. The foreign plan investment objectives for the international hedge pooled pension fund are to provide positive investment returns in all market conditions over the medium to long-term and the investment strategies include the use of advanced derivative techniques that result in a highly diversified portfolio. As indicated in the tables above, investment risk for both the domestic and foreign plans are controlled by maintaining a portfolio of assets that is diversified across a variety of asset classes and investment styles in order to minimize exposure with respect to the size of individual securities and industry concentration. The domestic plans use a variety of investment managers who are evaluated on a quarterly basis while the foreign plan uses two investment funds to manage its assets. The asset allocation policies of the plans are consistent with the established investment objectives and risk tolerances. The asset allocation policies are developed by examining the historical relationships of risk and return among asset classes, and are designed to provide the highest probability of meeting or exceeding the return objectives at the lowest possible risk.
Effective in 2013, the Company adopted a liability-driven investment approach for its U.S. pension assets as part of its defined benefit plan terminal funding strategy in order to minimize the volatility of the plans' funded status. The allocation to equity investments as a percentage of plan assets has been reduced and the equity investments are now diversified across low-cost index funds to capture higher expected long-term returns while minimizing cost. The increased fixed income allocation is invested in a manner such that any changes to the corporate bond yield curve will result in proportional changes to both the fixed income portfolio value and the plans' terminal funding liability. As the funded status of the plans improves (as measured on a termination basis), the Company will reduce the plans' equity exposure and increase the amount of fixed income investment that is aligned with the plans' expected benefit obligations. This process represents an ongoing reduction in equity return volatility risk that simultaneously reduces interest rate risk associated with both the plans' fixed income portfolio value and terminal funding liability. This approach is expected to significantly reduce the variability of total plan funding costs without increasing the Company's cumulative contributions. The foreign plan target allocation for 2015 is to split the pension assets broadly into 60.0% growth investments and 40.0% bond investments consistent with the portfolio benchmark for 2012.

Assumptions
The assumptions used in determining pension, supplemental retirement plans and post-retirement costs and the projected benefit obligation are as follows:
		For the Year Ended December 31,
		2014				2013				2012
Discount rate for projected benefit obligation		2.00%	-	3.65%		3.00%	-	4.50%		2.00%	-	4.40%
Discount rate for pension costs		3.00%	-	4.50%		2.00%	-	4.40%		3.00%	-	4.70%
Expected long-term average return on plan assets		5.83%	-	6.19%		5.36%	-	5.50%		5.81%	-	5.92%
Rate of compensation increase		2.00%				2.00%	-	3.00%		2.00%	-	3.00%
The Company utilizes long-term investment-grade bond yields as the basis for selecting a discount rate by which plan obligations are measured. An analysis of projected cash flows for each plan is performed in order to determine plan-specific duration. Discount rates are selected based on high quality corporate bond yields of similar durations.
During 2014, the Society of Actuaries released new mortality tables that reflect increased life expectancy over the previous tables.  The Company incorporated these new tables in the 2014 fair value measurement of its U.S. pension plans which resulted in an increase in the projected benefit obligation as of December 31, 2014.
For purposes of calculating the post-retirement health benefit cost, a medical inflation rate of 5.00% was assumed for 2014 and 6.00% for 2013. For 2013, the rate was assumed to decrease gradually to an ultimate rate of 5.00% by 2014. Once the rate reaches 5.00%, it is assumed to stay at 5.00% each year into the future. A one percentage point change in assumed health care cost trends does not have a significant effect on the amount of liabilities recorded in the consolidated balance sheet at December 31, 2014.
At December 31, 2014, the expected future benefit payments for the defined benefit and post-retirement health benefit plans were as follows:
Year Ended December 31,		Defined Benefit				Post-Retirement Health Benefits
		(Dollar amounts in millions)
2015		$	12.1			$	0.3
2016		12.1				0.3
2017		12.2				0.2
2018		12.2				0.2
2019		12				0.2
2020-2024		57				0.6
Other Plans
In conjunction with the acquisition of Reznor, the Company assumed a liability to fund certain post-retirement benefits of Reznor in Belgium. The assets of the Belgian defined benefit plan are composed of insurance policies. The contributions (or premiums) the Company pays are used to purchase insurance policies that provide for specific benefit payments to the plan participants. The benefit formula is determined independently by the Company upon retirement of an individual plan participant, the insurance contracts purchased are converted to provide specific benefits for the participant.  As of December 31, 2014, the fair value of these plan assets was approximately $1.5 million and are considered to be Level 3 financial instruments. The total liability as of December 31, 21014 was approximately $0.5 million.

FAIR VALUE	12 Months Ended

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 and Disclosures". 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 (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 December 31, 2014 or 2013.
	Pension Plan Assets -- See Note 13, "Pension, Profit Sharing and Other Post-Retirement Benefits", for further information surrounding the Company's valuation of pension plan assets.
	Measured on a Non-Recurring Basis
	During 2014, the Company recorded an impairment charge related to long-lived assets and goodwill associated with the AVC segments. The non-recurring fair value measurements of these assets were primarily determined using unobservable inputs and as such, these fair value measurements are classified within Level 3 of the fair value hierarchy. See Note 3, "Goodwill and Other Intangible Assets" for further discussion surrounding this charge.
	Financial Instruments Not Recorded at Fair Value
	The carrying value and fair values of financial instruments not recorded at fair value in the consolidated balance sheets at December 31, 2014 and 2013 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 December 31, 2014, the fair value of the Company's long-term indebtedness was approximately $68.6 million higher than the amount on the Company's accompanying consolidated balance sheet, before approximately $4.8 million of unamortized debt premium and approximately $1.9 million of unamortized debt discount. At December 31, 2013, the fair value of the Company’s long-term indebtedness was approximately $107.7 million higher than the amount on the Company's consolidated balance sheet, before net unamortized debt premium of approximately $4.5 million.  The Company determined the fair market value of its 10% Notes and 8.5% Notes using available market quotes from published sources (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.

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	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 principal reporting segments (see Note 9, “Segment Information and Concentration of Credit Risk”), the Company manufactures and sells, primarily in the United States, Canada and Europe, with additional manufacturing in China and Mexico, a wide variety of products principally for the remodeling and replacement markets, the residential and commercial new construction markets, and the personal and enterprise computer markets.
	The accompanying 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. As a result of certain acquisitions as discussed in Note 2, “Acquisitions”, the operating results of these acquired entities are included in the Company’s consolidated results of operations from the date of acquisition prospectively. The Company has entered into certain arrangements with an independent third party in Mexico related to the Company’s manufacturing operations in Mexico. The Company has evaluated the operating entities that were formed under these arrangements and has determined that these entities are variable interest entities in accordance with Accounting Standards Codification ("ASC") 810, "Consolidation" ("ASC 810"). The Company has concluded that it is the primary beneficiary of these entities since it has both the power to direct activities that most significantly impact the entities' economic performance and the obligation to absorb losses that could potentially be significant since the Company is responsible for all operating decisions and all operating costs of these entities. As a result, the Company is consolidating the results of these entities in accordance with ASC 810. For the year ended December 31, 2014, the results of operations of these entities included in the Company’s statement of operations were not material.
Accounting Policies and Use of Estimates	Accounting Policies and Use of Estimates
	The preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles involves estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expense during the reporting periods. Certain of the Company’s accounting policies require the application of judgment in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. The Company periodically evaluates the judgments and estimates used for its critical accounting policies to ensure that such judgments and estimates are reasonable for its interim and year-end reporting requirements. These judgments and estimates are based on the Company’s historical experience, current trends and information available from other sources, as appropriate. If different conditions result from those assumptions used in the Company’s judgments, the results could be materially different from the Company’s estimates.
Recognition of Sales and Related Costs, Incentives and Allowances	Recognition of Sales and Related Costs, Incentives and Allowances
	The Company generally recognizes sales when passage of title and risk of loss to the customer occurs, which is typically upon shipment, and has procedures in place at each of its subsidiaries to ensure that an accurate cut-off is obtained for each reporting period. The Company considers revenue to be realized or realizable and earned when all of the following criteria are met: persuasive evidence of a sales arrangement exists; delivery has occurred or services have been rendered; the price is fixed or determinable; and collectability is reasonably assured.
	Certain of the Company's arrangements with its customers, principally in the Commercial Air Solutions ("CAS") segment, are multiple-element arrangements that can include any combination of products and services such as extended warranties, installation and start up testing as deliverables. With the exception of certain extended warranty arrangements, substantially all of the deliverables within the Company’s multiple element arrangements are delivered within a one year period. In accordance with ASC 605-25, "Revenue Recognition", the Company believes that any undelivered elements can be accounted for separately from the delivered element when the delivered elements have value to its customers on a stand-alone basis. Accordingly, revenue for an undelivered element is deferred until delivery occurs. The Company is required to allocate revenue to multiple element arrangements based on the relative fair value of each element’s estimated selling price. The Company uses vendor-specific objective evidence (“VSOE”), if available, to determine the selling price of each element. The Company determines VSOE based on its normal pricing and discounting practices for the specific product or service when sold on a stand-alone basis. In determining VSOE, the Company's policy requires a substantial majority of selling prices for a product or service to be within a reasonably narrow range. The Company also considers the class of customer, method of distribution, and the geographies into which its products and services are sold when determining VSOE. If VSOE is not available, the Company uses third-party evidence or its best estimated selling price to determine the selling price for each element.
	Allowances for cash discounts, volume rebates, other customer incentive programs and gross customer returns, among others, are recorded as of the later of the date at which the revenues are recognized or the incentive is offered and are generally recorded as a reduction of sales at the time of sale based upon the estimated future outcome. Certain customer incentives are recorded as a charge to selling, general and administrative expense, net (“SG&A”) if there is a separable, identifiable benefit related to the incentive that can be quantified. These customer incentives principally relate to promotional advertising allowances where the customer is required to obtain approval and provide support for the associated advertising expenditures in order to receive the incentive consideration. Cash discounts, volume rebates and other customer incentive programs are based upon certain percentages agreed to with the Company’s various customers, which are typically earned by the customer over an annual period. The Company records periodic estimates for these amounts based upon the historical results to date, estimated future results through the end of the contract period, and the contractual provisions of the customer agreements. For calendar year customer agreements, the Company is able to adjust its periodic estimates to actual amounts as of December 31 each year based upon the contractual provisions of the customer agreements. For those customers who have agreements that are not on a calendar year cycle, the Company records estimates at December 31 consistent with the above described methodology. Customers are generally not required to provide collateral for purchases. As a result, at the end of any given reporting period, the amounts recorded for these allowances are based upon estimates of the likely outcome of future sales with the applicable customers and may require adjustment in the future if the actual outcome differs. The Company believes that its procedures for estimating such amounts are reasonable.
	Certain of the Company’s arrangements provide for rights of returns. Customer returns are recorded on an actual basis throughout the year and also include an estimate at the end of each reporting period for future customer returns related to sales recorded prior to the end of the period. The Company generally estimates customer returns based upon the time lag that historically occurs between the date of the sale and the date of the return, while also factoring in any new business conditions that might impact the historical analysis, such as new product introductions. The Company believes that its procedures for estimating such amounts are reasonable and allow it to make reliable estimates which are based on a historical large, homogeneous pool of transactions and history of returns. If a reliable estimate of returns cannot be made, the Company defers revenues until the right of return lapses. If the Company defers the recognition of arrangement consideration due to the fact that the criteria for revenue recognition are not achieved, the Company also defers the recognition of the related direct and incremental costs, primarily product costs, and recognizes such costs upon recognition of the corresponding deferred revenues. The amount of deferred direct and incremental costs at December 31, 2014 and 2013, respectively, was not material.
	The Company also provides for its estimate of warranty, bad debts and shipping costs at the time of sale. Shipping and warranty costs are included in cost of products sold ("COGS"). Provisions for the estimated allowance for doubtful accounts are recorded in SG&A. The amounts recorded are generally based upon historically derived percentages while also factoring in any new business conditions that might impact the historical analysis such as changes in economic conditions, past due and nonperforming accounts, bankruptcies or other events affecting particular customers. The Company periodically evaluates the adequacy of its allowance for doubtful accounts recorded in its consolidated balance sheet to ensure the adequacy of the recorded provisions. The analysis for allowance for doubtful accounts often involves subjective analysis of a particular customer’s ability to pay. As a result, significant judgment is required in determining the appropriate amounts to record and such judgments may prove to be incorrect in the future. The Company believes that its procedures for estimating such amounts are reasonable.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash equivalents consist of short-term highly liquid investments with original maturities of three months or less which are readily convertible into cash.
	The Company has classified as restricted in the accompanying consolidated balance sheet certain cash and cash equivalents that are not fully available for use in its operations.
Inventories	Inventories
	Inventories in the accompanying consolidated balance sheet are valued at the lower of cost or market. At December 31, 2014, approximately $127.7 million of the Company's total inventories were valued on the last-in, first-out method (“LIFO”) of accounting. Under the first-in, first-out method (“FIFO”), such inventories would have been approximately $1.7 million lower at December 31, 2014. At December 31, 2013, approximately $78.4 million of the Company's total inventories were valued under LIFO. Under FIFO, such inventories would have been approximately $0.7 million lower at December 31, 2013. All other inventories were valued under the FIFO method.
	In connection with both LIFO and FIFO inventories, the Company records provisions, as appropriate, to write-down obsolete and excess inventory to estimated net realizable value. The process for evaluating obsolete and excess inventory often requires the Company to make subjective judgments and estimates concerning future sales levels, quantities, and prices at which such inventory will be able to be sold in the normal course of business. Accelerating the disposal process or incorrect estimates of future sales potential may cause the actual results to differ from the estimates at the time such inventory is disposed or sold.
	Inventory acquired in business combinations is recorded to cost of products sold over the period in which the inventory will be sold.
Depreciation and Amortization	Depreciation and Amortization
	Depreciation and amortization of property and equipment, including capital leases, is provided on a straight-line basis over their estimated useful lives, which are generally as follows:
	Buildings and improvements	3 - 43 years
	Machinery and equipment, including leases	1 - 13 years
	Leasehold improvements	Shorter of the original lease term or the estimated useful life
	Expenditures for maintenance and repairs are expensed when incurred. Expenditures for renewals and betterments are capitalized. When assets are sold, or otherwise disposed, the cost and related accumulated depreciation are eliminated and the resulting gain or loss is recognized.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets
	The Company accounts for acquired goodwill in accordance with ASC 805, "Business Combinations" ("ASC 805") and ASC 350, “Intangibles - Goodwill and Other” (“ASC 350”), which involves judgment with respect to the determination of the valuation of the acquired assets and liabilities assumed in order to determine the final amount of goodwill recorded in a purchase. See Note 3, “Goodwill and Other Intangible Assets”, for a discussion of these judgments.
Pensions and Post-Retirement Health Benefits	Pensions and Post-Retirement Health Benefits
	The Company accounts for pensions and post-retirement health benefits in accordance with ASC 715, “Compensation - Retirement Benefits,” (“ASC 715”). The accounting for pensions requires the estimation of items such as the long-term average return on plan assets, the discount rate, the rate of compensation increase, and the assumed medical cost inflation rate. Such estimates require a significant amount of judgment. See Note 13, “Pension, Profit Sharing and Other Post-Retirement Benefits”, for a discussion of these judgments.
Insurance Liabilities	Insurance Liabilities
	The Company records insurance liabilities and related expenses for health, workers compensation, product and general liability losses, and other insurance reserves and expenses in accordance with either the contractual terms of its policies or, if self-insured, the total liabilities that are estimable and probable as of the reporting date. Insurance liabilities are recorded as current liabilities to the extent they are expected to be paid in the succeeding year, with the remaining requirements classified as long-term liabilities. The accounting for self-insured plans requires that significant judgments and estimates be made both with respect to the future liabilities to be paid for known claims, and incurred but not reported claims as of the reporting date. The Company considers historical trends when determining the appropriate insurance liabilities to record in the consolidated balance sheet for a substantial portion of its workers compensation and general and product liability losses. In certain cases where partial insurance coverage exists, the Company must estimate the portion of the liability that will be covered by existing insurance policies to arrive at the net expected liability to the Company. Receivables for insurance recoveries for product liability claims are recorded as assets, on an undiscounted basis. These recoveries are estimated based on the contractual arrangements with vendors and other third parties, and historical trends.
Income Taxes	Income Taxes
	The Company accounts for income taxes using the liability method in accordance with ASC 740, “Income Taxes” (“ASC 740”), which requires that the deferred tax consequences of temporary differences between the amounts recorded in the Company’s consolidated financial statements, and the amounts included in the Company’s federal, state and foreign income tax returns, be recognized in the balance sheet. As the Company generally does not file its income tax returns until well after the closing process for the December 31 financial statements is complete, the amounts recorded at December 31 reflect estimates of what the final amounts will be when the actual income tax returns are filed for that fiscal year. In addition, estimates are often required with respect to, among other things, the appropriate state income tax rates to use in the various states that Nortek and its subsidiaries are required to file, the potential utilization of operating and capital loss carry-forwards, and valuation allowances required, if any, for tax assets that may not be realizable in the future. ASC 740 requires balance sheet classification of current and long-term deferred income tax assets and liabilities based upon the classification of the underlying asset or liability that gives rise to a temporary difference (see Note 8, “Income Taxes”). The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for income taxes.
Share-Based Compensation Expense	Share-Based Compensation Expense
	The Company measures share-based compensation expense at fair value in accordance with ASC 718, “Compensation - Stock Compensation” (“ASC 718”), and recognizes such expense, net of estimated forfeitures, over the vesting period of the share-based awards. See Note 12, “Share-Based Compensation”, for further information regarding the Company's share-based compensation programs.
Exit and Disposal Activities	Exit and Disposal Activities
	The Company accounts for termination benefits based on the nature of the underlying arrangement. In instances where the Company has a defined plan, a past practice of providing a similar level of benefits or a statutorily defined termination benefit arrangement, the Company recognizes a liability for ongoing termination benefits when it is probable the employees will be entitled to the benefits and the amount can be reasonably estimated.
	In instances where the Company provides termination benefits and an ongoing arrangement does not exist, the timing of measurement of a liability for one-time employee termination benefits depends on whether employees are required to render service until they are terminated in order to receive the termination benefits and, if so, whether employees will be retained to render service beyond a minimum retention period. If employees are not required to render service until they are terminated in order to receive the termination benefits (that is, if employees are entitled to receive the termination benefits regardless of when they leave) or if employees will not be retained to render service beyond the minimum retention period, a liability for the termination benefits is measured and recognized at its fair value at the communication date. If employees are required to render service until they are terminated in order to receive the termination benefits and will be retained to render service beyond the minimum retention period, a liability for the termination benefits is measured initially at the communication date based on the fair value of the liability as of the termination date and recognized ratably over the future service period.
	A liability, measured at its fair value, for costs to terminate a contract before the end of its term is recognized when the Company terminates the contract in accordance with the contract terms. A liability for costs that will continue to be incurred under a contract for its remaining term without economic benefit to the Company is recognized at the cease-use date. If the contract is an operating lease, the fair value of the liability at the cease-use date is determined based on the remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized under the lease, and reduced by estimated sublease rentals that could be reasonably obtained for the property, even if the Company does not intend to enter into a sublease. Remaining lease rentals are not reduced to an amount less than zero.
	Other costs associated with an exit or disposal activity include, but are not limited to, costs to consolidate or close facilities and relocate employees. A liability for other costs associated with an exit or disposal activity is measured and recognized at its fair value in the period in which the liability is incurred (generally, when goods or services associated with the activity are received).
	See Note 5, “Exit and Disposal Activities”, for further information regarding the Company’s exit and disposal activities.
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. See Note 6, “Commitments and Contingencies”, for further information regarding the Company’s commitments and contingencies.
Research and Development	Research and Development
	The Company’s research and development activities are principally related to new product development. Recorded in SG&A, research and development costs were approximately $75.4 million, $65.5 million and $59.4 million for 2014, 2013 and 2012, respectively, and represented approximately 3.0%, 2.9%, and 2.7% of the Company’s consolidated net sales for 2014, 2013 and 2012, respectively.
Foreign Currency Translation	Foreign Currency Translation
	The financial statements of subsidiaries located outside of the United States are generally measured using the foreign subsidiary's local currency as the functional currency. The Company translates the assets and liabilities of its foreign subsidiaries at the exchange rates in effect at year-end. Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive income (loss) included in stockholders’ investment. Net sales, costs and expenses are translated using average exchange rates in effect during the year. Transaction gains and losses are recorded in SG&A.
New Accounting Pronouncements	New Accounting Pronouncements
	In August 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40) ("ASU 2014-15"), which provides guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The amendments require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term "substantial doubt", (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and early adoption is permitted. The Company will adopt this pronouncement in the first quarter of 2017 and does not expect adoption to have a material effect on the Company's consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718) ("ASU 2014-12"), which clarifies the accounting for share based payments in which the terms of the award provide that a performance target can be achieved after the requisite service period. ASU 2014-12 is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted and an entity may apply the amendments in ASU 2014-12 either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Company will adopt this pronouncement in the first quarter of 2016 and is currently evaluating the impact, if any, adoption will have on its financial position and results of operations.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 is a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle under ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also specifies the accounting for some costs to obtain or fulfill a contract with a customer. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted and an entity may apply the amendments in ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 at the date of initial application. The Company will adopt this pronouncement in the first quarter of 2017 and is currently evaluating both the method of adoption and the impact adoption will have on its financial position and results of operations. In evaluating the method of adoption, the Company is considering a number of factors, including the disclosure requirements and related processes and controls required, as well as, the overall industry and peer public company adoption method trends.
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08"), which changes the criteria for reporting discontinued operations. ASU 2014-08 will also require additional disclosures about discontinued operations including, among others, the major classes of line items constituting the pretax profit and loss of the discontinued operation, either the total operating and investing cash flow of the discontinued operation or the depreciation, amortization, capital expenditures, and significant operating and investing non-cash items of the discontinued operation, a reconciliation of the major classes of assets and liabilities of the discontinued operation classified as held for sale to total assets and total liabilities of the disposal group classified as held for sale that is presented on the face of the balance sheet, and a reconciliation of the major classes of line items constituting the pretax profit or loss of the discontinued operation to the after-tax profit or loss of the discontinued operation that is presented on the face of the income statement. ASU 2014-08 also requires entities to provide disclosures about a disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation and expands the disclosures about an entity's significant continuing involvement with a discontinued operation. ASU 2014-08 is effective prospectively for both (1) disposals of components of an entity and (2) businesses that, on acquisition are classified as held for sale, that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. As of December 31, 2014, there have been no disposals or classifications as held for sale that would be subject to ASU 2014-08. As such, the Company will adopt this standard in the first quarter of 2015.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (“ASU 2013-11”), which is intended to provide guidance regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The standard clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when certain situations exist at the reporting date and is effective for annual reporting periods beginning on or after December 15, 2013 and subsequent interim periods, with early adoption permitted. The adoption of this standard did not have a material effect on the Company's consolidated financial statements.
	In February 2013, the FASB issued 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 adoption of this standard did not have a material effect on the Company's financial position or results of operations.
Fiscal Period	The Company operates on a calendar year and for its interim periods operates on a 4-4-5 fiscal calendar, where each fiscal quarter 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.
