Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and judgments. These estimates and judgments affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities (if any) at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents: Cash and cash equivalents include cash in banks and highly liquid investments with original maturities of three months or less. Accounts Receivable, Net of Allowances: Allowances for doubtful accounts are maintained against accounts receivable for estimated losses resulting from the inability of customers to make required payments. These allowances are based on both recent trends of certain customers estimated to be a greater credit risk as well as general trends of the entire customer pool. Accounts are written off against the allowance when it becomes evident collection will not occur. Inventories: Inventories are stated at the lower of cost or market. The weighted average method is used for coal inventory. KC retail inventories are stated at the lower of cost or market using the retail inventory method. The first-in, first-out (“FIFO”) method is used with respect to all other inventories. Reserves are maintained for estimated obsolescence or excess inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. Upon a subsequent sale or disposal of the impaired inventory, the corresponding reserve for impaired value is relieved to ensure that the cost basis of the inventory reflects any write-downs. Property, Plant and Equipment, Net: Property, plant and equipment are initially recorded at cost. Depreciation, depletion and amortization are provided in amounts sufficient to amortize the cost of the assets, including assets recorded under capital leases, over their estimated useful lives using the straight-line method. Buildings and building improvements are depreciated using a 40 year life or, at NACoal, over the life of the mine, which is 30 years. Estimated lives for machinery and equipment range from three to 15 years. Leasehold improvements are depreciated over the shorter of the estimated useful life or the term of the lease. The units-of-production method is used to amortize certain tooling for sourced products and certain coal-related assets based on estimated recoverable tonnages. Repairs and maintenance costs are generally expensed when incurred. Asset retirement costs associated with asset retirement obligations are capitalized with the carrying amount of the related long-lived asset and depreciated over the asset's estimated useful life. Long-Lived Assets: The Company periodically evaluates long-lived assets for impairment when changes in circumstances or the occurrence of certain events indicate the carrying amount of an asset may not be recoverable. Upon identification of indicators of impairment, the Company evaluates the carrying value of the asset by comparing the estimated future undiscounted cash flows generated from the use of the asset and its eventual disposition with the asset's net carrying value. If the carrying value of an asset is considered impaired, an impairment charge is recorded for the amount that the carrying value of the long-lived asset exceeds its fair value. Fair value is estimated as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Coal Supply Agreement: The coal supply agreement represents a long-term supply agreement with NACoal's customer and was recorded based on the fair value at the date of acquisition. The coal supply agreement is amortized based on units of production over the term of the agreement, which is estimated to be 30 years. The Company reviews identified intangible assets for impairment when changes in circumstances or the occurrence of certain events indicate potential impairment. Self-insurance Liabilities: The Company is generally self-insured for product liability, environmental liability, medical claims, certain workers’ compensation claims and certain closed mine liabilities. For product liability, catastrophic insurance coverage is retained for potentially significant individual claims. An estimated provision for claims reported and for claims incurred but not yet reported under the self-insurance programs is recorded and revised periodically based on industry trends, historical experience and management judgment. In addition, industry trends are considered within management's judgment for valuing claims. Changes in assumptions for such matters as legal judgments and settlements, inflation rates, medical costs and actual experience could cause estimates to change in the near term. Revenue Recognition: Revenues are generally recognized when title transfers and risk of loss passes to the customer. Under its mining contracts, the Company recognizes revenue as the coal or limerock is delivered or services are performed. Revenues at HBB are recognized when customer orders are completed and shipped. Revenues at KC are recognized at the point of sale when payment is made and customers take possession of the merchandise in stores. The Company's products generally are not sold with the right of return. Based on the Company's historical experience, a portion of KC and HBB products sold are estimated to be returned due to reasons such as buyer remorse, duplicate gifts received, product failure and excess inventory stocked by the customer, which, subject to certain terms and conditions, the Company will agree to accept. The Company records estimated reductions to revenues at the time of the sale based upon this historical experience and the limited right of return provided to the Company's customers. The Company also records estimated reductions to revenues for customer programs and incentive offerings, including special pricing agreements, price competition, promotions and other volume-based incentives. At HBB, net sales represent gross sales less cooperative advertising, other volume-based incentives, estimated returns and allowances for defective products. Additionally, the Company provides for the estimated cost of product warranties at the time revenues are recognized. At KC, retail markdowns are incorporated into KC's retail method of accounting for cost of sales. Advertising Costs: Advertising costs, except for direct response advertising, are expensed as incurred. Total advertising expense was $21.8 million, $20.4 million and $20.1 million in 2015, 2014 and 2013, respectively. Included in these advertising costs are amounts related to cooperative advertising programs at HBB that are recorded as a reduction of sales in the Consolidated Statements of Operations as related revenues are recognized. Direct response advertising, which consists primarily of costs to produce television commercials for HBB products, is capitalized and amortized over the expected period of future benefits. No assets related to direct response advertising were capitalized at December 31, 2015 or 2014. Product Development Costs: Expenses associated with the development of new products and changes to existing products are charged to expense as incurred. These costs amounted to $9.6 million, $9.6 million and $8.1 million in 2015, 2014 and 2013, respectively. Shipping and Handling Costs: Shipping and handling costs billed to customers are recognized as revenue and shipping and handling costs incurred by the Company are included in cost of sales. Taxes Collected from Customers and Remitted to Governmental Authorities: The Company collects various taxes and fees as an agent in connection with the sale of products and remits these amounts to the respective taxing authorities. These taxes and fees have been presented on a net basis in the Consolidated Statements of Operations and are recorded as a liability until remitted to the respective taxing authority. Stock Compensation: The Company maintains long-term incentive programs at all of its subsidiaries. The parent company has stock compensation plans that allow the grant of shares of Class A common stock, subject to restrictions, as a means of retaining and rewarding selected employees for long-term performance and to increase ownership in the Company. Shares awarded under the plans are fully vested and entitle the stockholder to all rights of common stock ownership except that shares may not be assigned, pledged or otherwise transferred during the restriction period. In general, the restriction period ends at the earliest of (i) five years after the participant's retirement date, (ii) ten years from the award date, or (iii) the participant's death or permanent disability. Pursuant to the plans, the Company issued 37,986 and 32,591 shares related to the years ended December 31, 2015 and 2014, respectively. After the issuance of these shares, there were 163,182 shares of Class A common stock available for issuance under these plans. Compensation expense related to these share awards was $1.7 million ($1.1 million net of tax), $1.8 million ($1.2 million net of tax) and $0.9 million ($0.6 million net of tax) for the years ended December 31, 2015, 2014 and 2013, respectively. Compensation expense represents fair value based on the market price of the shares of Class A common stock at the grant date. The Company also has a stock compensation plan for non-employee directors of the Company under which a portion of the non-employee director's annual retainer is paid in restricted shares of Class A common stock. For the year ended December 31, 2015, $75,000 of the non-employee director's annual retainer of $131,000 was paid in restricted shares of Class A common stock. For the years December 31, 2014 and December 31, 2013, $69,000 of the non-employee director's annual retainer of $125,000 was paid in restricted shares of Class A common stock. Shares awarded under the plan are fully vested and entitle the stockholder to all rights of common stock ownership except that shares may not be assigned, pledged or otherwise transferred during the restriction period. In general, the restriction period ends at the earliest of (i) ten years from the award date, (ii) the date of the director's death or permanent disability, (iii) five years (or earlier with the approval of the Board of Directors) after the director's date of retirement from the Board of Directors, or (iv) the date the director has both retired from the Board of Directors and has reached age 70. Pursuant to this plan, the Company issued 11,496, 10,446 and 9,472 shares related to the years ended December 31, 2015, 2014 and 2013, respectively. In addition to the mandatory retainer fee received in restricted stock, directors may elect to receive shares of Class A common stock in lieu of cash for up to 100% of the balance of their annual retainer, meeting attendance fees, committee retainer and any committee chairman's fees. These voluntary shares are not subject to any restrictions. Total shares issued under voluntary elections were 2,553 in 2015, 1,335 in 2014, and 1,300 in 2013. After the issuance of these shares, there were 47,212 shares of Class A common stock available for issuance under this plan. Compensation expense related to these awards was $0.7 million ($0.5 million net of tax), $0.6 million ($0.4 million net of tax) and $0.6 million ($0.4 million net of tax) for the years ended December 31, 2015, 2014 and 2013, respectively. Compensation expense represents fair value based on the market price of the shares of Class A common stock at the grant date. Foreign Currency: Assets and liabilities of foreign operations are translated into U.S. dollars at the fiscal year-end exchange rate. The related translation adjustments are recorded as a separate component of stockholders’ equity. Revenues and expenses of all foreign operations are translated using average monthly exchange rates prevailing during the year. Financial Instruments and Derivative Financial Instruments: Financial instruments held by the Company include cash and cash equivalents, accounts receivable, accounts payable, revolving credit agreements, long-term debt, interest rate swap agreements and forward foreign currency exchange contracts. The Company does not hold or issue financial instruments or derivative financial instruments for trading purposes. 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 subsidiaries’ functional currencies. Changes in the fair value of forward foreign currency exchange contracts that are effective as hedges are recorded in Accumulated other comprehensive income (loss) (“AOCI”). Deferred gains or losses are reclassified from AOCI to the Consolidated Statement 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 the market rate of interest. Terms of the interest rate swap agreements require 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 predominately based upon LIBOR (London Interbank Offered Rate). 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 Consolidated Statement 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 income (expense)” section of the 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 “Other” in the “Other income (expense)” section of the Consolidated Statements of Operations. Cash flows from hedging activities are reported in the Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations. See Note 9 for further discussion of derivative financial instruments. Fair Value Measurements: The Company accounts for the fair value measurement of its financial assets and liabilities in accordance with U.S. generally accepted accounting principles, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. Described below are the three levels of inputs that may be used to measure fair value: Level 1 - Quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. Level 2 - Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3 - Unobservable inputs are used when little or no market data is available. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement. See Note 10 for further discussion of fair value measurements. Recently Issued Accounting Standards Accounting Standards Adopted in 2015: In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes." This update requires an entity to classify deferred tax liabilities and assets as noncurrent within a classified statement of financial position. ASU 2015-17 is effective for annual and interim reporting periods beginning after December 15, 2016. This update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early application is permitted as of the beginning of the interim or annual reporting period. The Company retrospectively adopted this guidance during the fourth quarter of 2015. Accordingly, the Company reclassified current deferred taxes to non-current on the December 31, 2014 Balance Sheet, which increased non-current deferred income taxes by $18.6 million. See Note 15 for further discussion of deferred taxes. Accounting Standards Not Yet Adopted: In May 2014, the FASB codified in ASC 606, "Revenue Recognition - Revenue from Contracts with Customers," which supersedes most current revenue recognition guidance, including industry-specific guidance, and requires an entity to recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring goods or services to customers and provide additional disclosures. As amended, the effective date for public entities is annual reporting periods beginning after December 15, 2017 and interim periods therein. As such, the Company will be required to adopt the standard in the first quarter of fiscal year 2018. Early adoption is not permitted before the first quarter of fiscal year 2017. ASC 606 may be adopted either using a full retrospective approach, in which the standard is applied to all of the periods presented, or a modified retrospective approach. The Company is currently evaluating which transition method to use and how ASC 606 will affect the Company's financial position, results of operations, cash flows and related disclosures. In August 2014, the FASB issued ASU No. 2014-15, "Preparation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern," to provide 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. Specifically, the amendments (1) provide a definition of the term “substantial doubt,” (2) require an evaluation every reporting period, (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 financial statements are issued. ASU 2014-15 is effective for fiscal years ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company does not expect the adoption of this guidance to have an effect on the Company's financial position, results of operations, cash flows or related disclosures. In April 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs," which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early application is permitted. In August 2015, the FASB issued ASU 2015-15, "Interest—Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements—Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update)." ASU 2015-15 amends Subtopic 835-30 to include that the SEC would not object to the deferral and presentation of debt issuance costs as an asset and subsequent amortization of debt issuance costs over the term of the line-of-credit arrangement, whether or not there are any outstanding borrowings on the line-of-credit arrangement. This guidance is effective for fiscal years (and interim reporting periods within fiscal years) beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material effect on the Company's financial position, results of operations, cash flows or related disclosures. In July 2015, the FASB issued ASU No. 2015-11, "Inventory - Simplifying the Measurement of Inventory," which requires that inventory be measured at lower of cost or net realizable value. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early application is permitted. The Company does not expect the adoption of this guidance to have a material effect on the Company's financial position, results of operations, cash flows and related disclosures. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which modifies how entities measure equity investments and present changes in the fair value of financial liabilities; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; changes presentation and disclosure requirements; and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application is permitted. The Company is evaluating the impact that this new guidance will have on the Company’s financial position, results of operations, cash flows and related disclosures. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)," which requires an entity to recognize assets and liabilities for the rights and obligations created by leased assets. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating how ASU 2016-02 will affect the Company's financial position, results of operations, cash flows and related disclosures.

Significant Accounting Policies

Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and judgments. These estimates and judgments affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities (if any) at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents: Cash and cash equivalents include cash in banks and highly liquid investments with original maturities of three months or less.

Accounts Receivable, Net of Allowances: Allowances for doubtful accounts are maintained against accounts receivable for estimated losses resulting from the inability of customers to make required payments. These allowances are based on both recent trends of certain customers estimated to be a greater credit risk as well as general trends of the entire customer pool. Accounts are written off against the allowance when it becomes evident collection will not occur.

Inventories: Inventories are stated at the lower of cost or market. The weighted average method is used for coal inventory. KC retail inventories are stated at the lower of cost or market using the retail inventory method. The first-in, first-out (“FIFO”) method is used with respect to all other inventories. Reserves are maintained for estimated obsolescence or excess inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. Upon a subsequent sale or disposal of the impaired inventory, the corresponding reserve for impaired value is relieved to ensure that the cost basis of the inventory reflects any write-downs.

Property, Plant and Equipment, Net: Property, plant and equipment are initially recorded at cost. Depreciation, depletion and amortization are provided in amounts sufficient to amortize the cost of the assets, including assets recorded under capital leases, over their estimated useful lives using the straight-line method. Buildings and building improvements are depreciated using a 40 year life or, at NACoal, over the life of the mine, which is 30 years. Estimated lives for machinery and equipment range from three to 15 years. Leasehold improvements are depreciated over the shorter of the estimated useful life or the term of the lease. The units-of-production method is used to amortize certain tooling for sourced products and certain coal-related assets based on estimated recoverable tonnages. Repairs and maintenance costs are generally expensed when incurred. Asset retirement costs associated with asset retirement obligations are capitalized with the carrying amount of the related long-lived asset and depreciated over the asset's estimated useful life.

Long-Lived Assets: The Company periodically evaluates long-lived assets for impairment when changes in circumstances or the occurrence of certain events indicate the carrying amount of an asset may not be recoverable. Upon identification of indicators of impairment, the Company evaluates the carrying value of the asset by comparing the estimated future undiscounted cash flows generated from the use of the asset and its eventual disposition with the asset's net carrying value. If the carrying value of an asset is considered impaired, an impairment charge is recorded for the amount that the carrying value of the long-lived asset exceeds its fair value. Fair value is estimated as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

Coal Supply Agreement: The coal supply agreement represents a long-term supply agreement with NACoal's customer and was recorded based on the fair value at the date of acquisition. The coal supply agreement is amortized based on units of production over the term of the agreement, which is estimated to be 30 years. The Company reviews identified intangible assets for impairment when changes in circumstances or the occurrence of certain events indicate potential impairment.

Self-insurance Liabilities: The Company is generally self-insured for product liability, environmental liability, medical claims, certain workers’ compensation claims and certain closed mine liabilities. For product liability, catastrophic insurance coverage is retained for potentially significant individual claims. An estimated provision for claims reported and for claims incurred but not yet reported under the self-insurance programs is recorded and revised periodically based on industry trends, historical experience and management judgment. In addition, industry trends are considered within management's judgment for valuing claims. Changes in assumptions for such matters as legal judgments and settlements, inflation rates, medical costs and actual experience could cause estimates to change in the near term.

Revenue Recognition: Revenues are generally recognized when title transfers and risk of loss passes to the customer. Under its mining contracts, the Company recognizes revenue as the coal or limerock is delivered or services are performed. Revenues at HBB are recognized when customer orders are completed and shipped. Revenues at KC are recognized at the point of sale when payment is made and customers take possession of the merchandise in stores.

The Company's products generally are not sold with the right of return. Based on the Company's historical experience, a portion of KC and HBB products sold are estimated to be returned due to reasons such as buyer remorse, duplicate gifts received, product failure and excess inventory stocked by the customer, which, subject to certain terms and conditions, the Company will agree to accept. The Company records estimated reductions to revenues at the time of the sale based upon this historical experience and the limited right of return provided to the Company's customers.

The Company also records estimated reductions to revenues for customer programs and incentive offerings, including special pricing agreements, price competition, promotions and other volume-based incentives. At HBB, net sales represent gross sales less cooperative advertising, other volume-based incentives, estimated returns and allowances for defective products. Additionally, the Company provides for the estimated cost of product warranties at the time revenues are recognized. At KC, retail markdowns are incorporated into KC's retail method of accounting for cost of sales.

Advertising Costs: Advertising costs, except for direct response advertising, are expensed as incurred. Total advertising expense was $21.8 million, $20.4 million and $20.1 million in 2015, 2014 and 2013, respectively. Included in these advertising costs are amounts related to cooperative advertising programs at HBB that are recorded as a reduction of sales in the Consolidated Statements of Operations as related revenues are recognized. Direct response advertising, which consists primarily of costs to produce television commercials for HBB products, is capitalized and amortized over the expected period of future benefits. No assets related to direct response advertising were capitalized at December 31, 2015 or 2014.

Product Development Costs: Expenses associated with the development of new products and changes to existing products are charged to expense as incurred. These costs amounted to $9.6 million, $9.6 million and $8.1 million in 2015, 2014 and 2013, respectively.

Shipping and Handling Costs: Shipping and handling costs billed to customers are recognized as revenue and shipping and handling costs incurred by the Company are included in cost of sales.

Taxes Collected from Customers and Remitted to Governmental Authorities: The Company collects various taxes and fees as an agent in connection with the sale of products and remits these amounts to the respective taxing authorities. These taxes and fees have been presented on a net basis in the Consolidated Statements of Operations and are recorded as a liability until remitted to the respective taxing authority.

Stock Compensation: The Company maintains long-term incentive programs at all of its subsidiaries. The parent company has stock compensation plans that allow the grant of shares of Class A common stock, subject to restrictions, as a means of retaining and rewarding selected employees for long-term performance and to increase ownership in the Company. Shares awarded under the plans are fully vested and entitle the stockholder to all rights of common stock ownership except that shares may not be assigned, pledged or otherwise transferred during the restriction period. In general, the restriction period ends at the earliest of (i) five years after the participant's retirement date, (ii) ten years from the award date, or (iii) the participant's death or permanent disability. Pursuant to the plans, the Company issued 37,986 and 32,591 shares related to the years ended December 31, 2015 and 2014, respectively. After the issuance of these shares, there were 163,182 shares of Class A common stock available for issuance under these plans. Compensation expense related to these share awards was $1.7 million ($1.1 million net of tax), $1.8 million ($1.2 million net of tax) and $0.9 million ($0.6 million net of tax) for the years ended December 31, 2015, 2014 and 2013, respectively. Compensation expense represents fair value based on the market price of the shares of Class A common stock at the grant date.

The Company also has a stock compensation plan for non-employee directors of the Company under which a portion of the non-employee director's annual retainer is paid in restricted shares of Class A common stock. For the year ended December 31, 2015, $75,000 of the non-employee director's annual retainer of $131,000 was paid in restricted shares of Class A common stock. For the years December 31, 2014 and December 31, 2013, $69,000 of the non-employee director's annual retainer of $125,000 was paid in restricted shares of Class A common stock. Shares awarded under the plan are fully vested and entitle the stockholder to all rights of common stock ownership except that shares may not be assigned, pledged or otherwise transferred during the restriction period. In general, the restriction period ends at the earliest of (i) ten years from the award date, (ii) the date of the director's death or permanent disability, (iii) five years (or earlier with the approval of the Board of Directors) after the director's date of retirement from the Board of Directors, or (iv) the date the director has both retired from the Board of Directors and has reached age 70. Pursuant to this plan, the Company issued 11,496, 10,446 and 9,472 shares related to the years ended December 31, 2015, 2014 and 2013, respectively. In addition to the mandatory retainer fee received in restricted stock, directors may elect to receive shares of Class A common stock in lieu of cash for up to 100% of the balance of their annual retainer, meeting attendance fees, committee retainer and any committee chairman's fees. These voluntary shares are not subject to any restrictions. Total shares issued under voluntary elections were 2,553 in 2015, 1,335 in 2014, and 1,300 in 2013. After the issuance of these shares, there were 47,212 shares of Class A common stock available for issuance under this plan. Compensation expense related to these awards was $0.7 million ($0.5 million net of tax), $0.6 million ($0.4 million net of tax) and $0.6 million ($0.4 million net of tax) for the years ended December 31, 2015, 2014 and 2013, respectively. Compensation expense represents fair value based on the market price of the shares of Class A common stock at the grant date.

Foreign Currency: Assets and liabilities of foreign operations are translated into U.S. dollars at the fiscal year-end exchange rate. The related translation adjustments are recorded as a separate component of stockholders’ equity. Revenues and expenses of all foreign operations are translated using average monthly exchange rates prevailing during the year.

Financial Instruments and Derivative Financial Instruments: Financial instruments held by the Company include cash and cash equivalents, accounts receivable, accounts payable, revolving credit agreements, long-term debt, interest rate swap agreements and forward foreign currency exchange contracts. The Company does not hold or issue financial instruments or derivative financial instruments for trading purposes.

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 subsidiaries’ functional currencies. Changes in the fair value of forward foreign currency exchange contracts that are effective as hedges are recorded in Accumulated other comprehensive income (loss) (“AOCI”). Deferred gains or losses are reclassified from AOCI to the Consolidated Statement 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 the market rate of interest. Terms of the interest rate swap agreements require 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 predominately based upon LIBOR (London Interbank Offered Rate). 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 Consolidated Statement 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 income (expense)” section of the 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 “Other” in the “Other income (expense)” section of the Consolidated Statements of Operations.

Cash flows from hedging activities are reported in the Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations.

See Note 9 for further discussion of derivative financial instruments.

Fair Value Measurements: The Company accounts for the fair value measurement of its financial assets and liabilities in accordance with U.S. generally accepted accounting principles, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

A fair value hierarchy requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value.

Described below are the three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

Level 2 - Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3 - Unobservable inputs are used when little or no market data is available.

The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement.

See Note 10 for further discussion of fair value measurements.

Recently Issued Accounting Standards

Accounting Standards Adopted in 2015: In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes." This update requires an entity to classify deferred tax liabilities and assets as noncurrent within a classified statement of financial position. ASU 2015-17 is effective for annual and interim reporting periods beginning after December 15, 2016. This update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early application is permitted as of the beginning of the interim or annual reporting period. The Company retrospectively adopted this guidance during the fourth quarter of 2015. Accordingly, the Company reclassified current deferred taxes to non-current on the December 31, 2014 Balance Sheet, which increased non-current deferred income taxes by $18.6 million. See Note 15 for further discussion of deferred taxes.

Accounting Standards Not Yet Adopted: In May 2014, the FASB codified in ASC 606, "Revenue Recognition - Revenue from Contracts with Customers," which supersedes most current revenue recognition guidance, including industry-specific guidance, and requires an entity to recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring goods or services to customers and provide additional disclosures. As amended, the effective date for public entities is annual reporting periods beginning after December 15, 2017 and interim periods therein. As such, the Company will be required to adopt the standard in the first quarter of fiscal year 2018. Early adoption is not permitted before the first quarter of fiscal year 2017. ASC 606 may be adopted either using a full retrospective approach, in which the standard is applied to all of the periods presented, or a modified retrospective approach. The Company is currently evaluating which transition method to use and how ASC 606 will affect the Company's financial position, results of operations, cash flows and related disclosures.

In August 2014, the FASB issued ASU No. 2014-15, "Preparation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern," to provide 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. Specifically, the amendments (1) provide a definition of the term “substantial doubt,” (2) require an evaluation every reporting period, (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 financial statements are issued. ASU 2014-15 is effective for fiscal years ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company does not expect the adoption of this guidance to have an effect on the Company's financial position, results of operations, cash flows or related disclosures.

In April 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs," which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early application is permitted. In August 2015, the FASB issued ASU 2015-15, "Interest—Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements—Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update)." ASU 2015-15 amends Subtopic 835-30 to include that the SEC would not object to the deferral and presentation of debt issuance costs as an asset and subsequent amortization of debt issuance costs over the term of the line-of-credit arrangement, whether or not there are any outstanding borrowings on the line-of-credit arrangement. This guidance is effective for fiscal years (and interim reporting periods within fiscal years) beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material effect on the Company's financial position, results of operations, cash flows or related disclosures.

In July 2015, the FASB issued ASU No. 2015-11, "Inventory - Simplifying the Measurement of Inventory," which requires that inventory be measured at lower of cost or net realizable value. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early application is permitted. The Company does not expect the adoption of this guidance to have a material effect on the Company's financial position, results of operations, cash flows and related disclosures.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which modifies how entities measure equity investments and present changes in the fair value of financial liabilities; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; changes presentation and disclosure requirements; and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application is permitted. The Company is evaluating the impact that this new guidance will have on the Company’s financial position, results of operations, cash flows and related disclosures.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)," which requires an entity to recognize assets and liabilities for the rights and obligations created by leased assets. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating how ASU 2016-02 will affect the Company's financial position, results of operations, cash flows and related disclosures.
