Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The Consolidated Financial Statements include the accounts of Drew Industries Incorporated and its wholly-owned subsidiaries (“Drew” and collectively with its subsidiaries, the “Company”). Drew has no unconsolidated subsidiaries. Drew, through its wholly-owned subsidiary, Lippert Components, Inc. and its subsidiaries (collectively, “Lippert Components” or “LCI”), supplies a broad array of components in the United States and abroad for the leading manufacturers of recreational vehicles (“RVs”) and manufactured homes and for the related aftermarkets of those industries, and also supplies components for adjacent industries including buses; trailers used to haul boats, livestock, equipment and other cargo; pontoon boats; modular housing; and factory-built mobile office units. At December 31, 2015 , the Company operated 42 manufacturing and distribution facilities. The RV and manufactured housing industries, as well as other industries where the Company sells products or where its products are used, historically have been seasonal and are generally at the highest levels when the weather is moderate. Accordingly, the Company’s sales and profits have generally been the highest in the second quarter and lowest in the fourth quarter. However, because of fluctuations in dealer inventories, the impact of international, national and regional economic conditions and consumer confidence on retail sales of RVs and other products for which the Company sells its components, the timing of dealer orders, and the impact of severe weather conditions on the timing of industry-wide shipments from time to time, current and future seasonal industry trends may be different than in prior years. The Company is not aware of any significant events, except as disclosed in the Notes to Consolidated Financial Statements, which occurred subsequent to the balance sheet date but prior to the filing of this report that would have a material impact on the Consolidated Financial Statements. All significant intercompany balances and transactions have been eliminated. Certain prior year balances have been reclassified to conform to current year presentation. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. Accounts Receivable Accounts receivable are stated at historical carrying value, net of write-offs and allowances. The Company establishes allowances based upon historical experience and any specific customer collection issues identified by the Company. Uncollectible accounts receivable are written off when a settlement is reached or when the Company has determined the balance will not be collected. Inventories Inventories are stated at the lower of cost (using the first-in, first-out method) or market. Cost includes material, labor and overhead; market is replacement cost or realizable value after allowance for costs of distribution. Fixed Assets Fixed assets which are owned are stated at cost less accumulated depreciation, and are depreciated on a straight-line basis over the estimated useful lives of the properties and equipment. Leasehold improvements and leased equipment are amortized over the shorter of the lives of the leases or the underlying assets. Maintenance and repair costs that do not improve service potential or extend economic life are expensed as incurred; significant improvements are capitalized. Income Taxes Deferred tax assets and liabilities are determined based on the temporary differences between the financial reporting and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. The Company accounts for uncertainty in tax positions by recognizing in its financial statements the impact of a tax position only if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Further, the Company assesses the tax benefits of the tax positions in its financial statements based on experience with similar tax positions, information obtained during the examination process and the advice of experts. The Company recognizes previously unrecognized tax benefits upon the earlier of the expiration of the period to assess tax in the applicable taxing jurisdiction or when the matter is constructively settled and upon changes in statutes or regulations and new case law or rulings. The Company classifies interest and penalties related to income taxes as income tax expense in its Consolidated Financial Statements. Goodwill Goodwill represents the excess of the total consideration given in an acquisition of a business over the fair value of the net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but instead is tested at the reporting unit level for impairment annually in November, or more frequently if certain circumstances indicate a possible impairment may exist. In 2015 and 2014 , the Company assessed qualitative factors of its reporting units to determine whether it was more likely than not the fair value of the reporting unit was less than its carrying amount, including goodwill. The qualitative impairment test consists of an assessment of qualitative factors, including general economic and industry conditions, market share and input costs. Other Intangible Assets Intangible assets with estimable useful lives are amortized, primarily on an accelerated basis, over their respective estimated useful lives to their estimated residual values, and reviewed for impairment. The amortization of other intangible assets is done using a method, straight-line or accelerated, which best reflects the pattern in which the estimated future economic benefits of the asset will be consumed. The useful lives of intangible assets are determined after considering the expected cash flows and other specific facts and circumstances related to each intangible asset. Impairment of Long-Lived Assets Long-lived assets, other than goodwill, are tested for impairment when changes in circumstances indicate their carrying value may not be recoverable. A determination of impairment, if any, is made based on the undiscounted value of estimated future cash flows, salvage value or expected net sales proceeds, depending on the circumstances. Impairment is measured as the excess of the carrying value over the estimated fair value of such assets. Asset Retirement Obligations Asset retirement obligations are legal obligations associated with the retirement of long-lived assets. The Company records asset retirement obligations on certain of its owned and leased facilities and leased machinery and equipment. These liabilities are initially recorded at fair value and are adjusted for changes resulting from revisions to the timing or the amount of the original estimate. Environmental Liabilities Accruals for environmental matters are recorded when it is probable a liability has been incurred and the amount of the liability can be reasonably estimated, based upon current law and existing technologies. These amounts, which are not discounted and are exclusive of claims against potentially responsible third parties, are adjusted periodically as assessment and remediation efforts progress or additional technical or legal information becomes available. Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies and remedial activities, advances in technology, changes in environmental laws and regulations and their application, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other potentially responsible parties and the Company’s ability to obtain contributions from other parties, and the lengthy time periods over which site remediation occurs. It is possible some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably against the Company, and could materially affect operating results when resolved in future periods. Financial Instruments The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximated their fair value due to the short-term nature of these instruments. Stock-Based Compensation All stock-based compensation awards are expensed over their vesting period, based on fair value. For awards having a service-only vesting condition, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service periods. For awards with a performance vesting condition, which are subject to certain pre-established performance targets, the Company recognizes stock-based compensation expense on a graded-vesting basis to the extent it is probable the performance targets will be met. The fair value for stock options is determined using the Black-Scholes option-pricing model, while the fair values of deferred stock units, restricted stock and stock awards are based on the market price of the Company’s Common Stock, all on the date the stock-based awards are granted. Revenue Recognition The Company recognizes revenue when products are shipped and the customer takes ownership and assumes risk of loss, collectability is reasonably assured, and the sales price is fixed or determinable. Sales taxes collected from customers and remitted to governmental authorities, which are not significant, are accounted for on a net basis and therefore are excluded from net sales in the Consolidated Statements of Income. Shipping and Handling Costs The Company records shipping and handling costs within selling, general and administrative expenses. Such costs aggregated $45.8 million , $40.9 million and $36.4 million in the years ended December 31, 2015 , 2014 and 2013 , respectively. Legal Costs The Company expenses all legal costs associated with litigation as incurred. Legal expenses are included in selling, general and administrative expenses in the Consolidated Statements of Income. Fair Value Measurements Fair value is determined using a hierarchy that has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant unobservable inputs. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, net sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to product returns, sales and purchase rebates, accounts receivable, inventories, goodwill and other intangible assets, net assets of acquired businesses, income taxes, warranty and product recall obligations, self-insurance obligations, lease terminations, asset retirement obligations, long-lived assets, post-retirement benefits, stock-based compensation, segment allocations, contingent consideration, environmental liabilities, contingencies and litigation. The Company bases its estimates on historical experience, other available information and various other assumptions believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other resources. Actual results and events could differ significantly from management estimates.

Segment Reporting

Segment Reporting	12 Months Ended
	Dec. 31, 2015
Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING The Company has two reportable segments: the recreational vehicle products segment (the “RV Segment”) and the manufactured housing products segment (the “MH Segment”). Intersegment sales are insignificant. The RV Segment, which accounted for 92 percent , 90 percent , and 88 percent of consolidated net sales for the years ended December 31, 2015 , 2014 and 2013 respectively, manufactures or distributes a variety of products used in the production of RVs, including: ● Steel chassis for towable RVs ● Furniture and mattresses ● Axles and suspension solutions for towable RVs ● Entry, luggage, patio and ramp doors ● Slide-out mechanisms and solutions ● Electric and manual entry steps ● Thermoformed bath, kitchen and other products ● Awnings and awning accessories ● Windows ● Electronic components ● Manual, electric and hydraulic stabilizer and ● LED televisions, sound systems, navigation ● Chassis components ● Other accessories The Company also supplies certain of these products to the RV aftermarket, and to adjacent industries, including buses and trailers used to haul boats, livestock, equipment and other cargo, and pontoon boats. Approximately 73 percent of the Company’s RV Segment net sales in 2015 were of products to original equipment manufacturers (“OEMs”) of travel trailer and fifth-wheel RVs. The MH Segment, which accounted for 8 percent , 10 percent and 12 percent of consolidated net sales for the years ended December 31, 2015 , 2014 and 2013 , respectively, manufactures or distributes a variety of products used in the production of manufactured homes, including: ●Vinyl and aluminum windows ●Aluminum and vinyl patio doors ●Thermoformed bath and kitchen products ●Steel chassis and related components ●Steel and fiberglass entry doors ●Axles The Company also supplies certain of these products to the manufactured housing aftermarket, and to adjacent industries, including modular housing and mobile office units. Certain of the Company’s MH Segment customers manufacture both manufactured homes and modular homes, and certain of the products manufactured by the Company are suitable for both types of homes. As a result, the Company is not always able to determine in which type of home its products are installed. Decisions concerning the allocation of the Company’s resources are made by the Company’s key executives, with oversight by the Board of Directors. This group evaluates the performance of each segment based upon segment operating profit or loss, generally defined as income or loss before interest and income taxes. Decisions concerning the allocation of resources are also based on each segment’s utilization of assets. Management of debt is a corporate function. The accounting policies of the RV and MH Segments are the same as those described in Note 1 of the Notes to Consolidated Financial Statements. Corporate expenses are allocated between the segments based upon net sales. Accretion related to contingent consideration and other non-segment items are included in the segment to which they relate.

This change improves accuracy, but has no impact on total RV Segment net sales or trends. Prior periods have been reclassified to conform to this presentation. Potential Future Changes to Reporting Segments Over the past several years, largely due to the growth the Company has experienced in its RV Segment, the MH Segment is now a smaller part of the Company. Net sales to manufactured housing OEMs are 6 percent of consolidated net sales for the year ending December 31, 2015 . In addition, the Company has recently increased its focus on the significant opportunities in the aftermarket. The Company continues to evaluate the information provided to its Chief Operating Decision Maker (“CODM”), and assess how changes to its reporting structures would be used by the CODM to assess the performance of the Company’s operating segments and make decisions about resource allocations. Any such changes could necessitate a revision to the operating segments the Company reports.

Debt Disclosure [Abstract]
Long-Term Indebtedness	LONG-TERM INDEBTEDNESS At December 31, 2015 , the Company had no outstanding borrowings on its line of credit. At December 31, 2014 , the Company had $15.7 million of outstanding borrowings on its line of credit at a weighted average interest rate of 1.9 percent . On February 24, 2014, the Company entered into a $75.0 million line of credit (the “Credit Agreement”) with JPMorgan Chase Bank, N.A. and Wells Fargo Bank, N.A. On March 3, 2015, in accordance with the terms of the Credit Agreement, the Company increased its line of credit by $25.0 million to $100.0 million . Interest on borrowings under the line of credit is designated from time to time by the Company as either (i) the Prime Rate, minus a rate ranging from 0.75 to 1.0 percent (minus 1.0 percent at December 31, 2015 ), but not less than 1.5 percent , or (ii) LIBOR, plus additional interest ranging from 1.75 to 2.0 percent (plus 1.75 percent at December 31, 2015 ) depending on the Company’s performance and financial condition. The Credit Agreement expires on January 1, 2019 . At December 31, 2015 and 2014 , the Company had $2.7 million and $1.9 million , respectively, in standby letters of credit under the line of credit. Availability under the Company’s line of credit was $97.3 million at December 31, 2015 . On February 24, 2014, the Company also entered into a $150.0 million “shelf-loan” facility with Prudential Investment Management, Inc. and its affiliates (“Prudential”). The facility provides for Prudential to consider purchasing, at the Company’s request, in one or a series of transactions, Senior Promissory Notes of the Company in the aggregate principal amount of up to $150.0 million , to mature no more than twelve years after the date of original issue of each Senior Promissory Note. Prudential has no obligation to purchase the Senior Promissory Notes. Interest payable on the Senior Promissory Notes will be at rates determined by Prudential within five business days after the Company issues a request to Prudential. This facility expires on February 24, 2017 . On March 20, 2015, the Company issued $50.0 million of Senior Promissory Notes to Prudential for a term of five years, at a fixed interest rate of 3.35 percent per annum, payable quarterly in arrears, of which the entire amount was outstanding at December 31, 2015 . Availability under the Company’s “shelf-loan” facility, subject to the approval of Prudential, was $100.0 million at December 31, 2015 . At December 31, 2015 , the fair value of the Company’s long-term debt approximates the carrying value, as estimated using quoted market prices and discounted future cash flows based on similar borrowing arrangements. Borrowings under both the line of credit and the “shelf-loan” facility are secured on a pari-passu basis by first priority liens on the capital stock or other equity interests of each of the Company’s direct and indirect subsidiaries. Pursuant to the Credit Agreement and “shelf-loan” facility, at December 31, 2015 and 2014 , the Company was required to maintain minimum interest and fixed charge coverages, and to meet certain other financial requirements. At December 31, 2015 and 2014 , the Company was in compliance with all such requirements, and expects to remain in compliance for the next twelve months. Availability under both the Credit Agreement and the “shelf-loan” facilities is subject to a maximum leverage ratio covenant which limits the amount of consolidated outstanding indebtedness to 2.5 times the trailing twelve-month EBITDA, as defined in the agreements. This limitation did not impact the Company’s borrowing availability at December 31, 2015 . The remaining availability under these facilities was $197.3 million at December 31, 2015 . The Company believes the availability under the Credit Agreement and “shelf-loan” facility in conjunction with cash from operations is adequate to finance the Company’s anticipated cash requirements for the next twelve months.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The provision for income taxes in the Consolidated Statements of Income was as follows for the years ended December 31: (In thousands) 2015 2014 2013 Current: Federal $ 31,292 $ 32,142 $ 23,430 State 7,670 6,142 4,129 Total current provision $ 38,962 $ 38,284 $ 27,559 Deferred: Federal $ 466 $ (4,545 ) $ 68 State 596 (948 ) 201 Total deferred provision $ 1,062 $ (5,493 ) $ 269 Provision for income taxes $ 40,024 $ 32,791 $ 27,828 The provision for income taxes differs from the amount computed by applying the federal statutory rate to income before income taxes for the following reasons for the years ended December 31: (In thousands) 2015 2014 2013 Income tax at federal statutory rate $ 40,029 $ 33,270 $ 27,281 State income tax, net of federal income tax impact 5,373 3,376 2,815 Manufacturing credit pursuant to Jobs Creation Act (2,336 ) (2,258 ) (1,444 ) Federal tax credits (1,049 ) (681 ) (747 ) Other (1,993 ) (916 ) (77 ) Provision for income taxes $ 40,024 $ 32,791 $ 27,828 At December 31, 2015 , federal income taxes receivable of $8.1 million and state income taxes receivable of $0.4 million were included in prepaid expenses and other current assets. At December 31, 2014 , federal and state income taxes receivable of $1.3 million were included in prepaid expenses and other current assets, and state income taxes payable of $0.8 million were included in accrued expenses and other current liabilities. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities were as follows at December 31: (In thousands) 2015 2014 Deferred tax assets: Goodwill and other intangible assets $ 11,879 $ 14,066 Stock-based compensation 7,428 7,172 Deferred compensation 5,310 5,040 Warranty 8,809 7,845 Inventory 5,974 3,897 Other 4,922 3,189 Total deferred tax assets 44,322 41,209 Deferred tax liabilities: Fixed assets (14,931 ) (10,756 ) Net deferred tax assets $ 29,391 $ 30,453 The Company concluded it is more likely than not the deferred tax assets at December 31, 2015 will be realized in the ordinary course of operations based on projected future taxable income and scheduling of deferred tax liabilities. Excess tax benefits on stock-based compensation of $9.0 million , $3.9 million and $1.5 million were credited directly to stockholders’ equity during the years ended December 31, 2015 , 2014 and 2013 , respectively, relating to tax benefits which exceeded the compensation cost for stock-based compensation recognized in the Consolidated Financial Statements. At December 31, 2015 , the remaining pool of excess tax benefits from prior exercises of stock-based compensation in stockholders’ equity was $23.4 million . Unrecognized Tax Benefits The following table reconciles the total amounts of unrecognized tax benefits, at December 31: (In thousands) 2015 2014 2013 Balance at beginning of period $ 1,526 $ 1,369 $ 1,701 Changes in tax positions of prior years 912 84 (29 ) Additions based on tax positions related to the current year 866 603 676 Payments (85 ) — (126 ) Closure of tax years (365 ) (530 ) (853 ) Balance at end of period $ 2,854 $ 1,526 $ 1,369 In addition, the total amount of accrued interest and penalties related to taxes was $0.2 million , $0.2 million and $0.2 million at December 31, 2015 , 2014 and 2013 , respectively. The total amount of unrecognized tax benefits, net of federal income tax benefits, of $2.7 million , $1.2 million and $1.0 million at December 31, 2015 , 2014 and 2013 , respectively, would, if recognized, increase the Company’s earnings, and lower the Company’s annual effective tax rate in the year of recognition. The Company periodically undergoes examinations by the Internal Revenue Service (“IRS”), as well as various state taxing authorities. The IRS and other taxing authorities may challenge certain deductions and positions reported by the Company on its income tax returns. For federal income tax purposes, the tax years 2012 through 2014 remain subject to examination. For Indiana state income tax purposes, the tax years 2012 through 2014 remain subject to examination. Approximately 80 percent of the Company’s operations are located in Indiana. The Company has assessed its risks associated with all tax return positions, and believes its tax reserve estimates reflect its best estimate of the deductions and positions it will be able to sustain, or it may be willing to concede as part of a settlement. At this time, the Company cannot estimate the range of reasonably possible change in its tax reserve estimates in 2016 . While these tax matters could materially affect operating results when resolved in future periods, it is management’s opinion that after final disposition, any monetary liability or financial impact to the Company beyond that provided for in the Consolidated Balance Sheet as of December 31, 2015 , would not be material to the Company’s financial position or annual results of operations.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Leases The Company’s lease commitments are primarily for real estate, machinery and equipment, and vehicles. The significant real estate leases provide for renewal options and require the Company to pay for property taxes and all other costs associated with the leased property. Future minimum lease payments under operating leases at December 31, 2015 are as follows ( in thousands ): 2016 $ 7,472 2017 6,761 2018 5,553 2019 4,752 2020 4,043 Thereafter 11,093 Total minimum lease payments $ 39,674 Rent expense for operating leases was $9.8 million , $8.6 million and $7.1 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Contingent Consideration In connection with several business acquisitions, if certain sales targets for the acquired products are achieved, the Company would pay additional cash consideration. The Company has recorded a liability for the fair value of this contingent consideration at December 31, 2015 and 2014 , based on the present value of the expected future cash flows using a market participant’s weighted average cost of capital of 13.9 percent and 15.0 percent , respectively. As required, the liability for this contingent consideration is measured at fair value quarterly, considering actual sales of the acquired products, updated sales projections, and the updated market participant weighted average cost of capital. Depending upon the weighted average costs of capital and future sales of the products which are subject to contingent consideration, the Company could record adjustments in future periods. The following table provides a reconciliation of the Company’s contingent consideration liability for the years ended December 31 : (In thousands) 2015 2014 2013 Balance at beginning of period $ 8,129 $ 7,414 $ 11,519 Acquisitions 4,766 3,370 — Payments (3,974 ) (3,739 ) (5,456 ) Accretion (a) 1,196 1,075 1,308 Fair value adjustments (a) 723 9 43 Balance at end of the period (b) 10,840 8,129 7,414 Less current portion in accrued expenses and other current liabilities (3,877 ) (3,622 ) (3,462 ) Total long-term portion in other long-term liabilities $ 6,963 $ 4,507 $ 3,952 (a) Recorded in selling, general and administrative expense in the Consolidated Statements of Income. (b) Amounts represent the fair value of estimated remaining payments. The total estimated remaining undiscounted payments as of December 31, 2015 are $14.4 million . The liability for contingent consideration expires at various dates through September 2029. Certain of the contingent consideration arrangements are subject to a maximum payment amount, while the remaining arrangements have no maximum contingent consideration. Furrion Distribution and Supply Agreement In July 2015, the Company entered into a 6 -year exclusive distribution and supply agreement with Furrion Limited (“Furrion”), a Hong Kong based firm that designs, engineers and manufactures premium electronics. This agreement provides the Company with the rights to distribute Furrion’s complete line of products to OEMs and aftermarket customers in the RV, specialty vehicle, utility trailer, horse trailer, marine, transit bus and school bus industries throughout the United States and Canada. Furrion currently supplies a premium line of LED televisions, sound systems, navigation systems, wireless backup cameras, solar prep units, power solutions and kitchen appliances, primarily to the RV industry. Furrion’s sales were approximately $35 million in 2014. In connection with this agreement, the Company acquired Furrion’s current inventory, as well as Furrion’s deposits on inventory scheduled for delivery, for approximately $11 million . In addition, the Company entered into the following minimum purchase obligations (“MPOs”): July 2015 - June 2016 $ 60 million July 2016 - June 2017 $ 90 million July 2017 - June 2018 $127 million July 2018 - June 2019 $172 million If the Company misses an MPO in any given year by more than ten percent, after taking into account excess purchases from the previous year, Furrion has the right to either terminate the distribution agreement with six months’ notice or remove exclusivity from the Company. If exclusivity is withdrawn, the Company, at its election, can terminate the distribution agreement with six months’ notice. Upon termination of the agreement, Furrion has agreed to purchase from the Company any non-obsolete stocks of Furrion products at the cost paid by the Company. After the first year, Furrion and the Company have agreed to review these MPOs on an annual basis and adjust the MPOs as necessary based upon current economic and industry conditions, the development and customer acceptance of new Furrion products, competition and other factors which impact demand for Furrion products. Product Recalls From time to time, the Company cooperates with and assists its customers on their product recalls and inquiries, and occasionally receives inquiries directly from the National Highway Traffic Safety Administration (“NHTSA”) regarding reported incidents involving the Company’s products. In February 2015, NHTSA opened a Preliminary Evaluation as a result of four Vehicle Owner Questionnaires (VOQs) alleging failure of the Company’s electrically powered step (“Coach Step”), which was primarily supplied for motorhome RVs between model years 2008 and 2014. The Coach Step was no longer manufactured after 2014. In March 2015, NHTSA sent a formal request for information, data and supporting documentation from the Company regarding the Coach Step, which the Company provided in April 2015. After a thorough review of the design and operation of the Coach Step, the Company initiated a voluntary safety recall in September 2015 of all double and triple Coach Steps. The Company recorded a reserve of $1.1 million for the contingent obligation in selling, general and administrative expenses. Environmental The Company’s operations are subject to certain Federal, state and local regulatory requirements relating to the use, storage, discharge and disposal of hazardous materials used during the manufacturing processes. Although the Company believes its operations have been consistent with prevailing industry standards, and are in substantial compliance with applicable environmental laws and regulations, one or more of the Company’s current or former operating sites, or adjacent sites owned by third-parties, have been affected by releases of hazardous materials. As a result, the Company may incur expenditures for future investigation and remediation of these sites, and recorded a pre-tax charge of $1.5 million related to environmental costs in 2015. Litigation In the normal course of business, the Company is subject to proceedings, lawsuits, regulatory agency inquiries and other claims. All such matters are subject to uncertainties and outcomes that are not predictable with assurance. While these matters could materially affect operating results when resolved in future periods, it is management’s opinion that, after final disposition, including anticipated insurance recoveries in certain cases, any monetary liability or financial impact to the Company beyond that provided in the Consolidated Balance Sheet as of December 31, 2015 , would not be material to the Company’s financial position or annual results of operations. Executive Succession and Severance In 2015, the Company initiated a focused program to reduce indirect labor costs. In connection with this cost reduction program, the Company incurred severance charges of $3.7 million . In 2013, in connection with the Company’s executive succession and corporate relocation from White Plains, New York to Elkhart County, Indiana, the Company recorded pre-tax charges of $1.9 million , related to contractual obligations for severance and the acceleration of equity awards held by certain employees whose employment terminated as a result of the executive succession and relocation to Indiana. The liability for executive succession and severance obligations were paid through 2015.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	STOCKHOLDERS' EQUITY Special Dividend On April 10, 2015, a special dividend of $2.00 per share of the Company’s Common Stock, representing an aggregate of $48.2 million , was paid to stockholders of record as of March 27, 2015. On January 6, 2014, a special dividend of $2.00 per share of the Company’s Common Stock, representing an aggregate of $46.7 million , was paid to stockholders of record as of December 20, 2013. In connection with these special dividends, holders of deferred stock units, restricted stock and stock awards were credited with deferred stock units, restricted stock or stock equal to $2.00 per special dividend for each deferred stock unit, share of restricted stock or stock award, representing $1.8 million in total for each of the 2015 and 2014 special dividends. In connection with each of these special cash dividends, the exercise price of all outstanding stock options was reduced by $2.00 per share. These reductions in exercise price were made pursuant to the terms of the outstanding awards, resulting in no incremental stock-based compensation expense. Stock-Based Awards Pursuant to the Drew Industries Incorporated Equity Award and Incentive Plan, as Amended and Restated (the “Equity Plan”), which was approved by stockholders in May 2011, the Company may grant to its directors, employees, and other eligible persons Common Stock-based awards, such as stock options, restricted stock and deferred stock units. All such awards granted under the Equity Plan must be approved by the Compensation Committee of Drew’s Board of Directors (the “Committee”). The Committee determines the period for which all such awards may be exercisable, but in no event may such an award be exercisable more than 10 years from the date of grant. The number of shares available under the Equity Plan, and the exercise price of all such awards granted under the Equity Plan, are subject to adjustments by the Committee to reflect stock splits, dividends, recapitalization, mergers, or other major corporate actions. At the Annual Meeting of Stockholders held on May 22, 2014 , stockholders approved an amendment to the Equity Plan to increase the number of shares of common stock available for issuance pursuant to awards by 1,678,632 shares. The number of shares available for granting awards was 1,305,440 , 1,389,506 and 246,368 at December 31, 2015 , 2014 and 2013 , respectively. Stock-based compensation resulted in charges to operations as follows for the years ended December 31: (In thousands) 2015 2014 2013 Stock options $ 974 $ 1,412 $ 2,325 Deferred stock units 7,023 4,343 5,425 Restricted stock 1,031 910 911 Stock awards 5,015 4,152 2,178 Stock-based compensation expense $ 14,043 $ 10,817 $ 10,839 Stock-based compensation expense is recorded in the Consolidated Statements of Income in the same line as cash compensation to those employees is recorded, primarily in selling, general and administrative expenses. In addition, for the years ended December 31, 2015 , 2014 and 2013 , the Company issued deferred stock units to certain executive officers in lieu of cash for a portion of prior year incentive compensation, in accordance with their compensation arrangements, of $2.0 million , $2.0 million and $0.1 million , respectively. In February 2016 , the Company issued deferred stock units valued at $0.3 million , to certain officers in lieu of cash for a portion of their 2015 incentive compensation in accordance with their compensation arrangements. Stock Options The Equity Plan provides for the grant of stock options that qualify as incentive stock options under Section 422 of the Internal Revenue Code, and non-qualified stock options. The exercise price for stock options granted under the Equity Plan must be at least equal to 100 percent of the fair market value of the shares subject to such stock option on the date of grant. The exercise price may be paid in cash or in shares of the Company’s Common Stock which have been held for a minimum of six months . Historically, upon exercise of stock options, new shares have been issued instead of using treasury shares. Outstanding stock options expire six years from the date of grant, and either vest ratably over the service period of five years for employees or, for certain executive officers, based on achievement of specified performance conditions. As a result of the Company’s executive succession and corporate relocation, the vesting of certain stock options was accelerated pursuant to contractual obligations with certain employees whose employment terminated as a result of the relocation to Indiana. Transactions in stock options under the Equity Plan are summarized as follows: Number of Option Shares Stock Option Exercise Price Weighted Average Exercise Price Outstanding at December 31, 2012 1,320,819 $ 8.09 - $29.11 $ 19.92 Exercised (574,288 ) $ 8.09 - $29.11 $ 23.04 Forfeited (22,870 ) $ 8.09 - $29.11 $ 19.36 Outstanding at December 31, 2013 723,661 $ 8.09 - $21.17 $ 15.46 Exercised (258,530 ) $ 6.09 - $19.17 $ 12.89 Forfeited (11,800 ) $6.09 - $19.17 $ 16.93 Reduction for cash dividend — $ 6.09 - $19.17 $ (2.00 ) Outstanding at December 31, 2014 453,331 $15.49 - $19.17 $ 16.89 Exercised (214,601 ) $13.49 - $19.17 $ 14.48 Forfeited (26,700 ) $13.49 - $19.17 $ 14.30 Reduction for cash dividend — $13.49 - $17.17 $ (2.00 ) Outstanding at December 31, 2015 212,030 $13.67 - $17.17 $ 15.38 Exercisable at December 31, 2015 162,170 $13.67 - $17.17 $ 14.83 Additional information for the exercise of stock options is as follows for the years ended December 31: (In thousands) 2015 2014 2013 Intrinsic value of stock options exercised $ 9,424 $ 7,860 $ 9,062 Cash receipts from stock options exercised $ 3,280 $ 3,333 $ 13,231 Income tax benefits from stock option exercises $ 2,885 $ 3,660 $ 3,473 Grant date fair value of stock options vested $ 1,055 $ 1,561 $ 2,252 The following table summarizes information about stock options outstanding at December 31, 2015 : Exercise Price Option Shares Outstanding Remaining Life in Years Option Shares Exercisable $ 13.67 108,450 0.9 108,450 $ 17.17 103,580 1.9 53,720 Total Shares 212,030 (a) 162,170 (a) (a) The aggregate intrinsic value for option shares outstanding and option shares exercisable is $9.6 million and $7.5 million , respectively. The weighted average remaining term for option shares outstanding and option shares exercisable is 1.4 years and 1.2 years , respectively. As of December 31, 2015 , there was $0.4 million of total unrecognized compensation costs related to unvested stock options, which are expected to be recognized over a weighted average remaining period of 0.9 years . Deferred Stock Units The Equity Plan provides for the grant or issuance of deferred stock units (“DSUs”) to directors, employees and other eligible persons. Recipients of DSUs are entitled to receive shares at the end of a specified deferral period. Holders of DSUs receive dividends granted to holders of the Common Stock, payable in additional DSUs, and are subject to the same vesting criteria as the original grant. DSUs vest (i) ratably over the service period, (ii) at a specified future date, or (iii) for certain officers, based on achievement of specified performance conditions. As a result of the Company’s executive succession and corporate relocation, the vesting of certain deferred stock units was accelerated pursuant to contractual obligations with certain employees whose employment terminated. In addition, DSUs are issued in lieu of cash compensation. Transactions in DSUs under the Equity Plan are summarized as follows: Number of Shares Stock Price Outstanding at December 31, 2012 613,754 $ 6.16 - $33.32 Issued 32,462 $33.84 - $48.53 Granted 140,461 $36.58 - $50.85 Forfeited (4,505 ) $30.50 Exercised (89,211 ) $20.20 - $30.65 Outstanding at December 31, 2013 692,961 $ 6.16 - $50.85 Issued 56,212 $36.68 - $51.46 Granted 187,490 $45.98 - $46.95 Dividend equivalents 27,532 $50.45 Forfeited (38,855 ) $26.98 - $50.89 Exercised (187,052 ) $19.98 - $50.89 Outstanding at December 31, 2014 738,288 $ 6.16 - $51.20 Issued 54,982 $52.20 - $60.92 Granted 90,184 $52.20 - $61.53 Dividend equivalents 20,922 $59.94 Forfeited (23,604 ) $30.50 - $60.29 Exercised (353,259 ) $20.89 - $51.46 Outstanding at December 31, 2015 527,513 $ 6.16 - $61.53 As of December 31, 2015 , there was $12.7 million of total unrecognized compensation costs related to DSUs, which is expected to be recognized over a weighted average remaining period of 1.9 years . Restricted Stock The Equity Plan provides for the grant of restricted stock to directors, employees and other eligible persons. The restriction period is established by the Committee, but may not be less than one year. Holders of restricted stock have all the rights of a stockholder of the Company, including the right to vote and the right to receive dividends granted to holders of the Common Stock, payable in additional shares of restricted stock, and subject to the same vesting criteria as the original grant. Shares of restricted stock are not transferable during the restriction period. Restricted stock grants, which were all made to directors, were as follows (in thousands except share and per share amounts): 2015 2014 2013 Granted 20,558 19,439 17,885 Stock price $58.96 - $61.53 $ 46.82 $ 50.89 Fair value of stock granted $ 1,220 $ 910 $ 910 As of December 31, 2015 , there was $1.0 million of total unrecognized compensation costs related to restricted stock, which is expected to be recognized over a weighted average remaining period of 0.8 years . Stock Awards In accordance with the Executive Employment and Non-Competition Agreements for various officers of the Company, such officers are entitled to receive an annual long-term award consisting of the right to earn shares of common stock. These shares are earned during the subsequent three year period based on growth in the Company’s earnings per diluted share. Transactions in stock awards under the Equity Plan are summarized as follows: Number of Shares Stock Price Outstanding at December 31, 2012 90,102 $26.88 Granted 103,500 $32.25 - $43.70 Outstanding at December 31, 2013 193,602 $26.88 - $43.70 Granted 103,500 $51.20 Dividend equivalents 7,675 $50.45 Exercised (31,959 ) $26.88 Outstanding at December 31, 2014 272,818 $26.88 - $51.45 Granted 96,010 $60.29 Dividend equivalents 8,992 $59.94 Forfeited (16,534 ) $60.29 Exercised (98,830 ) $26.88 - $43.70 Outstanding at December 31, 2015 262,456 $32.25 - $60.29 As of December 31, 2015 , there was $6.7 million of total unrecognized compensation costs related to outstanding stock awards, which is expected to be recognized over a weighted average remaining period of 1.5 years . Weighted Average Common Shares Outstanding The following reconciliation details the denominator used in the computation of basic and diluted earnings per share for the years ended December 31: (In thousands) 2015 2014 2013 Weighted average shares outstanding for basic earnings per share 24,295 23,911 23,321 Common stock equivalents pertaining to stock-based awards 355 423 432 Weighted average shares outstanding for diluted earnings per share 24,650 24,334 23,753 The weighted average diluted shares outstanding for the years ended December 31, 2015 , 2014 and 2013 , exclude the effect of 255,547 , 293,860 and 303,240 shares of common stock, respectively, subject to stock-based awards. Such shares were excluded from total diluted shares because they were anti-dilutive or the specified performance conditions that those shares were subject to were not yet achieved.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Recurring The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis at December 31: 2015 2014 (In thousands) Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets Deferred compensation $ 7,774 $ 7,774 $ — $ — $ 7,388 $ 7,388 $ — $ — Total assets $ 7,774 $ 7,774 $ — $ — $ 7,388 $ 7,388 $ — $ — Liabilities Contingent consideration $ 10,840 $ — $ — $ 10,840 $ 8,129 $ — $ — $ 8,129 Deferred compensation 11,836 11,836 — — 11,478 11,478 — — Total liabilities $ 22,676 $ 11,836 $ — $ 10,840 $ 19,607 $ 11,478 $ — $ 8,129 Deferred Compensation The Company has an Executive Non-Qualified Deferred Compensation Plan (the “Plan”). The amounts deferred under the Plan are credited with earnings or losses based upon changes in values of the notional investments elected by the Plan participants. The Company invests approximately 65 percent of the amounts deferred by the Plan participants in life insurance contracts, matching the investments elected by the Plan participants. Deferred compensation assets and liabilities were valued using a market approach based on the quoted market prices of identical instruments. Contingent Consideration Related to Acquisitions Liabilities for contingent consideration related to acquisitions were fair valued using management’s projections for long-term sales forecasts, including assumptions regarding market share gains and future industry-specific economic and market conditions, and a market participant’s weighted average cost of capital. Over the next six years , the Company’s long-term sales growth forecasts for products subject to contingent consideration arrangements average approximately 13 percent per year. For further information on the inputs used in determining the fair value, and a roll-forward of the contingent consideration liability, see Note 11 of the Notes to Consolidated Financial Statements. Changes in either of the inputs in isolation would result in a change in the fair value measurement. A change in the assumptions used for sales forecasts would result in a directionally similar change in the fair value liability, while a change in the weighted average cost of capital would result in a directionally opposite change in the fair value liability. If there is an increase in the fair value liability, the Company would record a charge to selling, general and administrative expenses, and if there is a decrease in the fair value liability, the Company would record a benefit in selling, general and administrative expenses. Non-recurring The following table presents the carrying value on the measurement date of any assets and liabilities which were measured at fair value and recorded at the lower of cost or fair value, on a non-recurring basis, using significant unobservable inputs (Level 3), and the corresponding non-recurring losses recognized during the years ended December 31 : 2015 2014 2013 (In thousands) Carrying Non-Recurring Carrying Non-Recurring Carrying Non-Recurring Assets Vacant owned facilities $ 2,537 $ — $ 3,863 $ — $ 3,197 $ 145 Other intangible assets — — — — — — Net assets of acquired businesses 28,727 — 66,169 — 4,382 — Total assets $ 31,264 $ — $ 70,032 $ — $ 7,579 $ 145 Vacant Owned Facilities During 2015 , the Company reviewed the recoverability of the carrying value of three vacant owned facilities, of which one of these facilities was sold and one was reopened. At December 31, 2015 , the Company had one vacant owned facility, with an estimated fair value of $3.1 million and a carrying value of $2.5 million , classified in fixed assets in the Consolidated Balance Sheets. During 2014 , the Company reviewed the recoverability of the carrying value of four vacant owned facilities. At December 31, 2014 , the Company had three vacant owned facilities with an estimated combined fair value of $4.2 million and a combined carrying value of $3.9 million , classified in fixed assets in the Consolidated Balance Sheets. During 2013 , the Company reviewed the recoverability of the carrying value of six vacant owned facilities. The fair value of two of these vacant owned facilities did not exceeded their carrying value, therefore an impairment charge of $0.1 million was recorded in selling, general, and administrative expenses in the Consolidated Statements of Income. At December 31, 2013 , the Company had three vacant owned facilities, with an estimated combined fair value of $3.6 million and a combined carrying value of $3.2 million , classified in fixed assets in the Consolidated Balance Sheets. The determination of fair value was based on the best information available, including internal cash flow estimates, market prices for similar assets, broker quotes and independent appraisals, as appropriate. Net Assets of Acquired Businesses The Company valued the assets and liabilities associated with the acquisitions of businesses on the respective acquisition dates. Depending upon the type of asset or liability acquired, the Company used different valuation techniques in determining the fair value. Those techniques included comparable market prices, long-term sales, profitability and cash flow forecasts, assumptions regarding future industry-specific economic and market conditions, a market participant’s weighted average cost of capital, as well as other techniques as circumstances required. For further information on acquired assets and liabilities, see Note 3 of the Notes to Consolidated Financial Statements.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes. This ASU requires entities with a classified balance sheet to present all deferred tax assets and liabilities as non-current. This ASU is effective for annual and interim periods beginning after December 15, 2016, and can be applied prospectively or retrospectively to adjustments with early adoption permitted at the beginning of an interim or annual reporting period. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company’s results of operations, cash flows or financial position. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. This ASU applies to restating prior periods to reflect adjustments made to provisional amounts recognized in a business combination. Under the new guidance, an acquirer must recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustment amounts are determined. This ASU is effective for annual and interim periods beginning after December 15, 2015, and is to be applied prospectively to adjustments to provisional amounts occurring after the effective date with early adoption permitted at the beginning of an interim or annual reporting period. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company’s results of operations, cash flows or financial position. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. This ASU applies to inventory measured using the first-in, first-out (“FIFO”) or average cost methods. Under the updated guidance, an entity should measure inventory that is within scope at the lower of cost and net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim or annual reporting period. Adoption of this ASU will not have a material impact on the Company’s results of operations, cash flows or financial position. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs . This ASU requires debt issuance costs be presented on the balance sheet as a direct reduction from the related debt liability rather than as an asset. Amortization of the costs would be reported as interest expense. The amendments in this ASU are to be applied retrospectively and are effective for interim and annual reporting periods beginning after December 15, 2015. Adoption of this ASU will not have a material impact on the Company’s results of operations, cash flows or financial position. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers . This ASU provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company 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. This ASU is for annual periods, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted for years beginning after December 15, 2016, to be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company’s results of operations, cash flows or financial position.

Summary of Significant Accoun23

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Consolidated Financial Statements include the accounts of Drew Industries Incorporated and its wholly-owned subsidiaries (“Drew” and collectively with its subsidiaries, the “Company”). Drew has no unconsolidated subsidiaries. Drew, through its wholly-owned subsidiary, Lippert Components, Inc. and its subsidiaries (collectively, “Lippert Components” or “LCI”), supplies a broad array of components in the United States and abroad for the leading manufacturers of recreational vehicles (“RVs”) and manufactured homes and for the related aftermarkets of those industries, and also supplies components for adjacent industries including buses; trailers used to haul boats, livestock, equipment and other cargo; pontoon boats; modular housing; and factory-built mobile office units. At December 31, 2015 , the Company operated 42 manufacturing and distribution facilities. The RV and manufactured housing industries, as well as other industries where the Company sells products or where its products are used, historically have been seasonal and are generally at the highest levels when the weather is moderate. Accordingly, the Company’s sales and profits have generally been the highest in the second quarter and lowest in the fourth quarter. However, because of fluctuations in dealer inventories, the impact of international, national and regional economic conditions and consumer confidence on retail sales of RVs and other products for which the Company sells its components, the timing of dealer orders, and the impact of severe weather conditions on the timing of industry-wide shipments from time to time, current and future seasonal industry trends may be different than in prior years. The Company is not aware of any significant events, except as disclosed in the Notes to Consolidated Financial Statements, which occurred subsequent to the balance sheet date but prior to the filing of this report that would have a material impact on the Consolidated Financial Statements. All significant intercompany balances and transactions have been eliminated. Certain prior year balances have been reclassified to conform to current year presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents.
Accounts Receivable	Accounts Receivable Accounts receivable are stated at historical carrying value, net of write-offs and allowances. The Company establishes allowances based upon historical experience and any specific customer collection issues identified by the Company. Uncollectible accounts receivable are written off when a settlement is reached or when the Company has determined the balance will not be collected.
Inventories	Inventories Inventories are stated at the lower of cost (using the first-in, first-out method) or market. Cost includes material, labor and overhead; market is replacement cost or realizable value after allowance for costs of distribution.
Fixed Assets	Fixed Assets Fixed assets which are owned are stated at cost less accumulated depreciation, and are depreciated on a straight-line basis over the estimated useful lives of the properties and equipment. Leasehold improvements and leased equipment are amortized over the shorter of the lives of the leases or the underlying assets. Maintenance and repair costs that do not improve service potential or extend economic life are expensed as incurred; significant improvements are capitalized.
Income Taxes	Income Taxes Deferred tax assets and liabilities are determined based on the temporary differences between the financial reporting and tax basis of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. The Company accounts for uncertainty in tax positions by recognizing in its financial statements the impact of a tax position only if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Further, the Company assesses the tax benefits of the tax positions in its financial statements based on experience with similar tax positions, information obtained during the examination process and the advice of experts. The Company recognizes previously unrecognized tax benefits upon the earlier of the expiration of the period to assess tax in the applicable taxing jurisdiction or when the matter is constructively settled and upon changes in statutes or regulations and new case law or rulings. The Company classifies interest and penalties related to income taxes as income tax expense in its Consolidated Financial Statements.
Goodwill	Goodwill Goodwill represents the excess of the total consideration given in an acquisition of a business over the fair value of the net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but instead is tested at the reporting unit level for impairment annually in November, or more frequently if certain circumstances indicate a possible impairment may exist. In 2015 and 2014 , the Company assessed qualitative factors of its reporting units to determine whether it was more likely than not the fair value of the reporting unit was less than its carrying amount, including goodwill. The qualitative impairment test consists of an assessment of qualitative factors, including general economic and industry conditions, market share and input costs.
Other Intangible Assets	Other Intangible Assets Intangible assets with estimable useful lives are amortized, primarily on an accelerated basis, over their respective estimated useful lives to their estimated residual values, and reviewed for impairment. The amortization of other intangible assets is done using a method, straight-line or accelerated, which best reflects the pattern in which the estimated future economic benefits of the asset will be consumed.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets, other than goodwill, are tested for impairment when changes in circumstances indicate their carrying value may not be recoverable. A determination of impairment, if any, is made based on the undiscounted value of estimated future cash flows, salvage value or expected net sales proceeds, depending on the circumstances. Impairment is measured as the excess of the carrying value over the estimated fair value of such assets.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations are legal obligations associated with the retirement of long-lived assets. The Company records asset retirement obligations on certain of its owned and leased facilities and leased machinery and equipment. These liabilities are initially recorded at fair value and are adjusted for changes resulting from revisions to the timing or the amount of the original estimate.
Environmental Liabilities	Environmental Liabilities Accruals for environmental matters are recorded when it is probable a liability has been incurred and the amount of the liability can be reasonably estimated, based upon current law and existing technologies. These amounts, which are not discounted and are exclusive of claims against potentially responsible third parties, are adjusted periodically as assessment and remediation efforts progress or additional technical or legal information becomes available. Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies and remedial activities, advances in technology, changes in environmental laws and regulations and their application, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other potentially responsible parties and the Company’s ability to obtain contributions from other parties, and the lengthy time periods over which site remediation occurs. It is possible some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably against the Company, and could materially affect operating results when resolved in future periods.
Financial Instruments	Financial Instruments The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximated their fair value due to the short-term nature of these instruments.
Stock-Based Compensation	Stock-Based Compensation All stock-based compensation awards are expensed over their vesting period, based on fair value. For awards having a service-only vesting condition, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service periods. For awards with a performance vesting condition, which are subject to certain pre-established performance targets, the Company recognizes stock-based compensation expense on a graded-vesting basis to the extent it is probable the performance targets will be met. The fair value for stock options is determined using the Black-Scholes option-pricing model, while the fair values of deferred stock units, restricted stock and stock awards are based on the market price of the Company’s Common Stock, all on the date the stock-based awards are granted.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when products are shipped and the customer takes ownership and assumes risk of loss, collectability is reasonably assured, and the sales price is fixed or determinable. Sales taxes collected from customers and remitted to governmental authorities, which are not significant, are accounted for on a net basis and therefore are excluded from net sales in the Consolidated Statements of Income.
Shipping and Handling Costs	Shipping and Handling Costs The Company records shipping and handling costs within selling, general and administrative expenses. Such costs aggregated $45.8 million , $40.9 million and $36.4 million in the years ended December 31, 2015 , 2014 and 2013 , respectively.
Legal Costs	Legal Costs The Company expenses all legal costs associated with litigation as incurred. Legal expenses are included in selling, general and administrative expenses in the Consolidated Statements of Income.
Fair Value Measurements	Fair Value Measurements Fair value is determined using a hierarchy that has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant unobservable inputs.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, net sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to product returns, sales and purchase rebates, accounts receivable, inventories, goodwill and other intangible assets, net assets of acquired businesses, income taxes, warranty and product recall obligations, self-insurance obligations, lease terminations, asset retirement obligations, long-lived assets, post-retirement benefits, stock-based compensation, segment allocations, contingent consideration, environmental liabilities, contingencies and litigation. The Company bases its estimates on historical experience, other available information and various other assumptions believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other resources. Actual results and events could differ significantly from management estimates.
