	Basis of Presentation
	The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of NACCO Industries, Inc. (the “parent company” or “NACCO”) and its wholly owned subsidiaries (collectively, “NACCO Industries, Inc. and Subsidiaries” or the “Company”). Intercompany accounts and transactions are eliminated in consolidation. The Company's subsidiaries operate in the following principal industries: mining, small appliances and specialty retail. The Company manages its subsidiaries primarily by industry.
	The North American Coal Corporation and its affiliated companies (collectively, “NACoal”) mine and market steam and metallurgical coal for use in power generation and steel production and provide selected value-added mining services for other natural resources companies. Hamilton Beach Brands, Inc. (“HBB”) is a leading designer, marketer and distributor of small electric household appliances, as well as commercial products for restaurants, bars and hotels. The Kitchen Collection, LLC (“KC”) is a national specialty retailer of kitchenware and gourmet foods operating under the Kitchen Collection® and Le Gourmet Chef® store names in outlet and traditional malls throughout the United States.
	These financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position of the Company at March 31, 2014 and the results of its operations, comprehensive income, cash flows and changes in equity for the three months ended March 31, 2014 and 2013 have been included. These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.
	The balance sheet at December 31, 2013 has been derived from the audited financial statements at that date but does not include all of the information or notes required by U.S. GAAP for complete financial statements.
	Operating results for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the remainder of the year ending December 31, 2014. The HBB and KC businesses are seasonal and a majority of revenues and operating profit typically occurs in the second half of the calendar year when sales of small electric household appliances to retailers and consumers increase significantly for the fall holiday-selling season. For further information regarding seasonality of these businesses, refer to the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.
	Certain amounts in the prior periods' Unaudited Condensed Consolidated Financial Statements have been reclassified to conform to the current period's presentation.

New Accounting Pronouncement or Change in Accounting Principle, Current Period Disclosures [Abstract]	'
Recently Issued Accounting Standards	'
	Recently Issued Accounting Standards
	Accounting Guidance Adopted in 2014: In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-08, which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations - that is, a major effect on the organization's operations and financial results should be presented as discontinued operations. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, the ASU requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. The Company adopted this guidance during the first quarter of 2014.  The adoption did not have an effect on the Company’s financial position, results of operations or cash flows.

	Stock Repurchase Program: On November 8, 2011, the Company announced that its Board of Directors approved the repurchase of up to $50 million of the Company's Class A Common Stock outstanding (the "2011 Stock Repurchase Program"). The original authorization for the 2011 Stock Repurchase Program expired on December 31, 2012; however, in November 2012 the Company's Board of Directors approved an extension of the 2011 Stock Repurchase Program through December 31, 2013. In total, the Company repurchased $35.6 million of Class A Common Stock under the 2011 Stock Repurchase Program.
	On November 12, 2013, the Company's Board of Directors terminated the 2011 Stock Repurchase Program and approved a new stock repurchase program (the "2013 Stock Repurchase Program") providing for the purchase of up to $60 million of the Company's Class A Common Stock outstanding through December 31, 2015. The timing and amount of any repurchases under the 2013 Stock Repurchase Program will be determined at the discretion of the Company's management based on a number of factors, including the availability of capital, other capital allocation alternatives and market conditions for the Company's Class A Common Stock. The 2013 Stock Repurchase Program does not require the Company to acquire any specific number of shares. It may be modified, suspended, extended or terminated by the Company at any time without prior notice and may be executed through open market purchases, privately negotiated transactions or otherwise. All or part of the repurchases under the 2013 Stock Repurchase Program may be implemented under a Rule 10b5-1 trading plan, which would allow repurchases under pre-set terms at times when the Company might otherwise be prevented from doing so.
	As of March 31, 2014, the Company had repurchased a total of 107,073 shares of Class A Common Stock for an aggregate purchase price of $5.9 million under the 2013 Stock Repurchase Program, including 90,978 shares at an average purchase price of $54.80 per share during the three months ended March 31, 2014.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'

	Derivative Financial Instruments
	The Company uses forward foreign currency exchange contracts to partially reduce risks related to transactions denominated in foreign currencies. The Company offsets fair value amounts related to foreign currency exchange contracts executed with the same counterparty. These contracts hedge firm commitments and forecasted transactions relating to cash flows associated with sales and purchases denominated in currencies other than the Company's subsidiaries' functional currencies. Changes in the fair value of forward foreign currency exchange contracts that are effective as hedges are recorded in AOCI. Deferred gains or losses are reclassified from AOCI to the Unaudited Condensed Consolidated Statements of Operations in the same period as the gains or losses from the underlying transactions are recorded and are generally recognized in cost of sales. The ineffective portion of derivatives that are classified as hedges is immediately recognized in earnings and generally recognized in cost of sales.
	The Company uses interest rate swap agreements to partially reduce risks related to floating rate financing agreements that are subject to changes in market rates of interest. Terms of the interest rate swap agreements provide for the Company to receive a variable interest rate and pay a fixed interest rate. The Company's interest rate swap agreements and its variable rate financings are based upon LIBOR. Changes in the fair value of interest rate swap agreements that are effective as hedges are recorded in AOCI. Deferred gains or losses are reclassified from AOCI to the Unaudited Condensed Consolidated Statements of Operations in the same period as the gains or losses from the underlying transactions are recorded and are generally recognized in interest expense. The ineffective portion of derivatives that are classified as hedges is immediately recognized in earnings and included on the line “Other” in the “Other expense (income)” section of the Unaudited Condensed Consolidated Statements of Operations.
	Interest rate swap agreements and forward foreign currency exchange contracts held by the Company have been designated as hedges of forecasted cash flows. The Company does not currently hold any nonderivative instruments designated as hedges or any derivatives designated as fair value hedges.
	The Company periodically enters into foreign currency exchange contracts that do not meet the criteria for hedge accounting. These derivatives are used to reduce the Company's exposure to foreign currency risk related to forecasted purchase or sales transactions or forecasted intercompany cash payments or settlements. Gains and losses on these derivatives are included on the line “Cost of sales” or “Other” in the “Other expense (income)” section of the Unaudited Condensed Consolidated Statements of Operations.
	Cash flows from hedging activities are reported in the Unaudited Condensed Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations.
	The Company measures its derivatives at fair value on a recurring basis using significant observable inputs, which is Level 2 as defined in the fair value hierarchy. The Company uses a present value technique that incorporates the LIBOR-swap curve, foreign currency spot rates and foreign currency forward rates to value its derivatives, including its interest rate swap agreements and foreign currency exchange contracts, and also incorporates the effect of its subsidiary and counterparty credit risk into the valuation.
	Foreign Currency Derivatives: HBB held forward foreign currency exchange contracts denominated primarily in Canadian dollars with total notional amounts of $11.0 million, $5.0 million and $8.6 million at March 31, 2014, December 31, 2013 and March 31, 2013, respectively. The fair value of these contracts approximated a net asset of $0.1 million at March 31, 2014, a net asset of less than $0.1 million at December 31, 2013 and a net asset of $0.2 million at March 31, 2013.
	Forward foreign currency exchange contracts that qualify for hedge accounting are used to hedge transactions expected to occur within the next twelve months. The mark-to-market effect of forward foreign currency exchange contracts that are considered effective as hedges have been included in AOCI. Based on market valuations at March 31, 2014, $0.1 million of the amount included in AOCI is expected to be reclassified as income into the Unaudited Condensed Consolidated Statements of Operations over the next twelve months, as the transactions occur.
	Interest Rate Derivatives: HBB has interest rate swap agreements that hedge interest payments on its one-month LIBOR borrowings. The following table summarizes the notional amounts, related rates and remaining terms of interest rate swap agreements active at March 31, 2014, delayed at December 31, 2013 and active at March 31, 2013, in millions:
	Notional Amount												Average Fixed Rate
	MARCH 31				DECEMBER 31				MARCH 31				MARCH 31			DECEMBER 31		MARCH 31		Remaining Term at March 31, 2014

	$	20			$	20			$	25			1.4	%		1.4	%	4	%	extending to January 2020
	The fair value of HBB's interest rate swap agreements was a net asset of $0.6 million, a net asset of $0.8 million, and a net liability of $0.2 million at March 31, 2014, December 31, 2013, and March 31, 2013, respectively. The mark-to-market effect of interest rate swap agreements that are considered effective as hedges have been included in AOCI. Based on market valuations at March 31, 2014, $0.1 million of the amount included in AOCI is expected to be reclassified as income into the Unaudited Condensed Consolidated Statements of Operations over the next twelve months, as cash flow payments are made in accordance with the interest rate swap agreements. The interest rate swap agreements held by HBB on March 31, 2014 are expected to continue to be effective as hedges.
	NACoal has interest rate swaps that hedge interest payments on its one-month LIBOR borrowings. The following table summarizes the notional amounts, related rates and remaining terms of the interest rate swap agreement active at March 31, 2014, December 31, 2013 and March 31, 2013 in millions:

	The fair value of NACoal's interest rate swap agreement was a net asset of less than $0.1 million and $0.1 million at March 31, 2014 and December 31, 2013, respectively. NACoal did not hold any derivative financial instruments at March 31, 2013. The mark-to-market effect of the interest rate swap agreement that is considered effective as a hedge has been included in AOCI. Based on market valuations at March 31, 2014, less than $0.1 million of the amount included in AOCI is expected to be reclassified as income into the Unaudited Condensed Consolidated Statements of Operations over the next twelve months, as cash flow payments are made in accordance with the interest rate swap agreement. The interest rate swap agreement held by NACoal on March 31, 2014 is expected to continue to be effective as a hedge.

	Bellaire Corporation (“Bellaire”) is a non-operating subsidiary of the Company with legacy liabilities relating to closed mining operations, primarily former Eastern U.S. underground coal mining operations. In connection with Bellaire's normal permit renewal with the Pennsylvania Department of Environmental Protection ("DEP"), Bellaire was notified during 2004 that in order to obtain renewal of the permit Bellaire would be required to establish a mine water treatment trust (the "Mine Water Treatment Trust"). On October 1, 2010, Bellaire executed a Post-Mining Treatment Trust Consent Order and Agreement with the DEP which established the Mine Water Treatment Trust to provide a financial assurance mechanism in order to assure the long-term treatment of post-mining discharges. Bellaire agreed to initially fund the Mine Water Treatment Trust with $5.0 million. Bellaire's Mine Water Treatment Trust invests in available for sale securities that are reported at fair value based upon quoted market prices in active markets for identical assets; therefore, they are classified as Level 1 within the fair value hierarchy and in the table above.
	The Company uses significant other observable inputs to value derivative instruments used to hedge foreign currency and interest rate risk; therefore, they are classified within Level 2 of the valuation hierarchy. The fair value for these contracts is determined based on exchange rates and interest rates, respectively. See Note 5 for further discussion of the Company's derivative financial instruments. The valuation techniques and Level 3 inputs used to estimate the fair value of contingent consideration payable in connection with the Company's 2012 acquisition of Reed Minerals are described below. There were no transfers into or out of Levels 1, 2 or 3 during the three months ended March 31, 2014 and 2013.
	The following table summarizes changes in Level 3 liabilities measured at fair value on a recurring basis:
				Contingent Consideration
	Balance at	January 1, 2014		$	1,581
	Accretion expense			8
	Payments			—
	Balance at	March 31, 2014		$	1,589
	The contingent consideration is structured as an earn-out payment to the sellers of Reed Minerals. The earn-out is calculated as a percentage by which the monthly average coal selling price exceeds an established threshold multiplied by the number of tons sold during the month. The earn-out period covers the first 15.0 million tons of coal sold from the Reed Minerals coal reserves. There is no monetary cap on the amount payable under this contingent payment arrangement. The liability for contingent consideration is included in Other long-term liabilities in the Unaudited Condensed Consolidated Balance Sheet. Earn-out payments, if payable, are paid quarterly. No earn-out payments were made during the three months ended March 31, 2014. Earn-out payments of less than $0.1 million were paid during the three months ended March 31, 2013.
	The estimated fair value of the contingent consideration was determined based on the income approach with key assumptions that include future projected metallurgical coal prices, forecasted coal deliveries and the estimated discount rate used to determine the present value of the projected contingent consideration payments. Future projected coal prices were estimated using a stochastic modeling methodology based on Geometric Brownian Motion with a risk neutral Monte Carlo simulation. Significant assumptions used in the model include coal price volatility and the risk-free interest rate based on U.S. Treasury yield curves with maturities consistent with the expected life of the contingent consideration. Volatility is considered a significant assumption and is based on historical coal prices. A significant increase or decrease in any of the aforementioned key assumptions related to the fair value measurement of the contingent consideration may result in a significantly higher or lower reported fair value for the contingent consideration liability.
	The future anticipated cash flow for the contingent consideration was discounted using an interest rate that appropriately captures a market participant's view of the risk associated with the liability. This fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement within the fair value hierarchy.
	Other Fair Value Measurement Disclosures: The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturities of these instruments. The fair values of revolving credit agreements and long-term debt, excluding capital leases, were determined using current rates offered for similar obligations taking into account subsidiary credit risk, which is Level 2 as defined in the fair value hierarchy. At March 31, 2014, both the fair value and the book value of the revolving credit agreements and long-term debt, excluding capital leases, was $210.6 million. At December 31, 2013, both the fair value and the book value of the revolving credit agreements and long-term debt, excluding capital leases, was $170.7 million. At March 31, 2013, the fair value of the revolving credit agreements and long-term debt, excluding capital leases, was $162.8 million compared with the book value of $162.0 million.

	Unconsolidated Subsidiaries
	NACoal has two consolidated mining operations: Mississippi Lignite Mining Company (“MLMC”) and Reed Minerals. NACoal also provides dragline mining services for independently owned limerock quarries in Florida. NACoal has ten wholly owned unconsolidated subsidiaries that each meet the definition of a variable interest entity and are accounted for using the equity method:
	The Coteau Properties Company ("Coteau")
	The Falkirk Mining Company ("Falkirk")
	The Sabine Mining Company ("Sabine")
	Demery Resources Company, LLC (“Demery”)
	Caddo Creek Resources Company, LLC (“Caddo Creek”)
	Coyote Creek Mining Company, LLC (“Coyote Creek”)
	Camino Real Fuels, LLC (“Camino Real”)
	Liberty Fuels Company, LLC (“Liberty”)
	NoDak Energy Services, LLC ("NoDak")
	North American Coal Corporation India Private Limited ("NACC India")
	Coteau, Falkirk and Sabine were developed between 1974 and 1981 and operate lignite coal mines under long-term contracts with various utility customers. Coteau, Falkirk and Sabine are capitalized primarily with debt financing, which the utility customers have arranged and guaranteed, and are without recourse to NACCO and NACoal. Demery, Caddo Creek, Coyote Creek, Camino Real and Liberty (collectively with Coteau, Falkirk and Sabine, the "Unconsolidated Mines") were formed to develop, construct and operate surface mines under long-term contracts. Demery commenced delivering coal to its customer in 2012 and is expected to reach full production levels in late 2015. Liberty commenced production in 2013 and is expected to increase production levels gradually from 0.5 to 1 million tons in 2014 to full production of approximately 4.7 million tons of coal annually in 2019. Caddo Creek, Coyote Creek and Camino Real are still in development and are not expected to be at full production for several years. NoDak was formed to operate and maintain a coal processing facility. NACC India was formed to provide technical advisory services to the third-party owners of a coal mine in India.
	The contracts with the customers of the Unconsolidated Mines provide for reimbursement at a price based on actual costs plus an agreed pre-tax profit per ton of coal sold or actual costs plus a management fee. Although NACoal owns 100% of the equity and manages the daily operations of these entities, the Company has determined that the equity capital provided by NACoal is not sufficient to adequately finance the ongoing activities or absorb any expected losses without additional support from the customers. The customers have a controlling financial interest and have the power to direct the activities that most significantly affect the economic performance of the entities. As a result, NACoal is not the primary beneficiary and therefore does not consolidate these entities' financial position or results of operations. The income taxes resulting from the operations of the Unconsolidated Mines are solely the responsibility of the Company. The pre-tax income from the Unconsolidated Mines is reported on the line “Earnings of unconsolidated mines” in the Unaudited Condensed Consolidated Statements of Operations, with related income taxes included in the provision for income taxes. The Company has included the pre-tax earnings of the Unconsolidated Mines above operating profit because they are an integral component of the Company's business and operating results. The pre-tax income from NoDak is reported on the line "Income from other unconsolidated affiliates" in the "Other expense (income)" section of the Unaudited Condensed Consolidated Statements of Operations, with the related income taxes included in the provision for income taxes. The net income from NACC India is reported on the line "Income from other unconsolidated affiliates" in the "Other expense (income)" section of the Unaudited Condensed Consolidated Statements of Operations.
	The investments in the Unconsolidated Mines, NoDak and NACC India and related tax positions totaled $34.1 million, $33.1 million, and $37.2 million at March 31, 2014, December 31, 2013, and March 31, 2013, respectively, and is included on the line “Other Non-current Assets” in the Unaudited Condensed Consolidated Balance Sheets. The Company's maximum risk of loss relating to these entities is limited to its invested capital, which was $5.3 million, $5.4 million, and $5.1 million at March 31, 2014, December 31, 2013, and March 31, 2013 respectively.
	Included in "Accounts receivable from affiliates" is $29.6 million, $27.9 million and $25.2 million as of March 31, 2014, December 31, 2013 and March 31, 2013, respectively due from Coyote Creek, primarily for the purchase of a dragline from NACoal.

	Various legal and regulatory proceedings and claims have been or may be asserted against NACCO and certain subsidiaries relating to the conduct of their businesses, including product liability, patent infringement, asbestos-related claims, environmental and other claims. These proceedings and claims are incidental to the ordinary course of business of the Company. Management believes that it has meritorious defenses and will vigorously defend the Company in these actions. Any costs that management estimates will be paid as a result of these claims are accrued when the liability is considered probable and the amount can be reasonably estimated. Although the ultimate disposition of these proceedings is not presently determinable, management believes, after consultation with its legal counsel, that the likelihood is remote that material costs will be incurred in excess of accruals already recognized.
	HBB is investigating or remediating historical environmental contamination at some current and former sites operated by HBB or by businesses it acquired. Based on the current stage of the investigation or remediation at each known site, HBB estimates the total investigation and remediation costs and the period of assessment and remediation activity required for each site. The estimate of future investigation and remediation costs is primarily based on variables associated with site clean-up, including, but not limited to, physical characteristics of the site, the nature and extent of the contamination and applicable regulatory programs and remediation standards. No assessment can fully characterize all subsurface conditions at a site. There is no assurance that additional assessment and remediation efforts will not result in adjustments to estimated remediation costs or the time frame for remediation at these sites.
	HBB's estimates of investigation and remediation costs may change if it discovers contamination at additional sites or additional contamination at known sites, if the effectiveness of its current remediation efforts change, if applicable federal or state regulations change or if HBB's estimate of the time required to remediate the sites changes. HBB's revised estimates may differ materially from original estimates.
	At March 31, 2014, December 31, 2013, and March 31, 2013, HBB had accrued an undiscounted obligation of $6.8 million, $6.9 million and $5.0 million, respectively, for environmental investigation and remediation activities at these sites. In addition, HBB estimates that it is reasonably possible that it may incur additional expenses in the range of $0 to $4.3 million related to the environmental investigation and remediation at these sites.

	The income tax provision includes U.S. federal, state and local, and foreign income taxes and is based on the application of a forecasted annual income tax rate applied to the current quarter's year-to-date pre-tax income or loss. In determining the estimated annual effective income tax rate, the Company analyzes various factors, including projections of the Company's annual earnings, taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, the Company's ability to use tax credits and net operating loss carryforwards, and available tax planning alternatives. Discrete items, including the effect of changes in tax laws, tax rates and certain circumstances with respect to valuation allowances or other unusual or non-recurring tax adjustments are reflected in the period in which they occur as an addition to, or reduction from, the income tax provision, rather than included in the estimated effective annual income tax rate.

	During the fourth quarter of 2013, NACoal acquired the equipment of National Coal of Alabama, Inc. ("NCOA") in exchange for the assumption of outstanding debt of $9.7 million associated with the acquired equipment. The outstanding debt was repaid concurrently with the acquisition of equipment utilizing borrowings under NACoal's existing unsecured revolving line of credit. In April 2014, NACoal acquired coal reserves and prepaid royalties and assumed certain reclamation obligations of NCOA. No cash payment was made to NCOA. This acquisition, which will be accounted for as a business combination, provides additional coal reserves in Alabama and equipment that can be used at NACoal's Reed Minerals mine, also located in Alabama.

Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position of the Company at March 31, 2014 and the results of its operations, comprehensive income, cash flows and changes in equity for the three months ended March 31, 2014 and 2013 have been included. These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.
	The balance sheet at December 31, 2013 has been derived from the audited financial statements at that date but does not include all of the information or notes required by U.S. GAAP for complete financial statements.
Reclassifications	'
	Certain amounts in the prior periods' Unaudited Condensed Consolidated Financial Statements have been reclassified to conform to the current period's presentation.
Derivatives	'
	The Company uses forward foreign currency exchange contracts to partially reduce risks related to transactions denominated in foreign currencies. The Company offsets fair value amounts related to foreign currency exchange contracts executed with the same counterparty. These contracts hedge firm commitments and forecasted transactions relating to cash flows associated with sales and purchases denominated in currencies other than the Company's subsidiaries' functional currencies. Changes in the fair value of forward foreign currency exchange contracts that are effective as hedges are recorded in AOCI. Deferred gains or losses are reclassified from AOCI to the Unaudited Condensed Consolidated Statements of Operations in the same period as the gains or losses from the underlying transactions are recorded and are generally recognized in cost of sales. The ineffective portion of derivatives that are classified as hedges is immediately recognized in earnings and generally recognized in cost of sales.
	The Company uses interest rate swap agreements to partially reduce risks related to floating rate financing agreements that are subject to changes in market rates of interest. Terms of the interest rate swap agreements provide for the Company to receive a variable interest rate and pay a fixed interest rate. The Company's interest rate swap agreements and its variable rate financings are based upon LIBOR. Changes in the fair value of interest rate swap agreements that are effective as hedges are recorded in AOCI. Deferred gains or losses are reclassified from AOCI to the Unaudited Condensed Consolidated Statements of Operations in the same period as the gains or losses from the underlying transactions are recorded and are generally recognized in interest expense. The ineffective portion of derivatives that are classified as hedges is immediately recognized in earnings and included on the line “Other” in the “Other expense (income)” section of the Unaudited Condensed Consolidated Statements of Operations.
	Interest rate swap agreements and forward foreign currency exchange contracts held by the Company have been designated as hedges of forecasted cash flows. The Company does not currently hold any nonderivative instruments designated as hedges or any derivatives designated as fair value hedges.
	The Company periodically enters into foreign currency exchange contracts that do not meet the criteria for hedge accounting. These derivatives are used to reduce the Company's exposure to foreign currency risk related to forecasted purchase or sales transactions or forecasted intercompany cash payments or settlements. Gains and losses on these derivatives are included on the line “Cost of sales” or “Other” in the “Other expense (income)” section of the Unaudited Condensed Consolidated Statements of Operations.
	Cash flows from hedging activities are reported in the Unaudited Condensed Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations.
	The Company measures its derivatives at fair value on a recurring basis using significant observable inputs, which is Level 2 as defined in the fair value hierarchy. The Company uses a present value technique that incorporates the LIBOR-swap curve, foreign currency spot rates and foreign currency forward rates to value its derivatives, including its interest rate swap agreements and foreign currency exchange contracts, and also incorporates the effect of its subsidiary and counterparty credit risk into the valuation.
Standard Product Warranty	'
	HBB provides a standard warranty to consumers for all of its products. The specific terms and conditions of those warranties vary depending upon the product brand. In general, if a product is returned under warranty, a refund is provided to the consumer by HBB's customer, the retailer. Generally, the retailer returns those products to HBB for a credit. The Company estimates the costs which may be incurred under its standard warranty programs and records a liability for such costs at the time product revenue is recognized.

	The income tax provision includes U.S. federal, state and local, and foreign income taxes and is based on the application of a forecasted annual income tax rate applied to the current quarter's year-to-date pre-tax income or loss. In determining the estimated annual effective income tax rate, the Company analyzes various factors, including projections of the Company's annual earnings, taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, the Company's ability to use tax credits and net operating loss carryforwards, and available tax planning alternatives. Discrete items, including the effect of changes in tax laws, tax rates and certain circumstances with respect to valuation allowances or other unusual or non-recurring tax adjustments are reflected in the period in which they occur as an addition to, or reduction from, the income tax provision, rather than included in the estimated effective annual income tax rate.
