Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Nature of Business Patrick Industries, Inc. (“Patrick” or the “Company”) operations consist of the manufacture and distribution of building products and materials for use primarily by the recreational vehicle (“RV”), manufactured housing (“MH”), and industrial markets for customers throughout the United States and Canada. At December 31, 2016 , the Company maintained 56 manufacturing plants and 22 distribution facilities located in 16 states. Patrick operates in two business segments: Manufacturing and Distribution. Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission and in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Patrick and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Unallocated expenses, when combined with the operating segments and after the elimination of intersegment revenues, total to the amounts included in the consolidated financial statements. Certain amounts in the prior years’ consolidated financial statements and notes have been reclassified to conform to the current year presentation. In preparation of Patrick’s consolidated financial statements as of December 31, 2016 , management evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date of issuance of the Form 10-K that required recognition or disclosure in the consolidated financial statements. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant estimates include the valuation of goodwill, the valuation of long-lived assets, the allowance for doubtful accounts, excess and obsolete inventories, and deferred tax asset valuation allowances. Actual results could differ from the amounts reported.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES Revenue Recognition The Company ships product based on specific orders from customers and revenue is recognized at the time of passage of title and risk of loss to the customer, which is generally upon delivery. The Company’s selling price is fixed and determined at the time of shipment and collectability is reasonably assured and not contingent upon the customer’s use or resale of the product. The Company records freight billed to customers in net sales. The corresponding costs incurred for shipping and handling related to these customer billed freight costs are recorded in warehouse and delivery expenses and aggregated $1.4 million , $1.1 million and $0.9 million for 2016 , 2015 and 2014 , respectively. Estimated costs related to customer volume rebates and sales incentives are accrued as a reduction of revenue at the time products are sold . Costs and Expenses Cost of goods sold includes material costs, direct and indirect labor, overhead expenses, inbound freight charges, inspection costs, internal transfer costs, receiving costs, and other costs. Warehouse and delivery expenses include salaries and wages, building rent and insurance, and other overhead costs related to distribution operations and delivery costs related to the shipment of finished and distributed products to customers. Purchasing costs are included in selling, general and administrative (“SG&A”) expenses. Stock Based Compensation Compensation expense related to the fair value of stock awards as of the grant date is calculated based on the Company’s closing stock price on the date of grant. In addition, the Company estimates the fair value of all stock option and stock appreciation rights ("SARS") awards as of the grant date by applying the Black-Scholes option-pricing model. The use of this valuation model involves assumptions that are judgmental and highly sensitive in the determination of compensation expense and include the dividend yield and exercise price. Expected volatilities take into consideration the historical volatility of the Company’s common stock. The expected term of options and SARS represents the period of time that the options and SARS granted are expected to be outstanding based on historical Company trends. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for instruments of a similar term. Income Per Common Share Basic net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding, plus the dilutive effect of stock options, stock appreciation rights, and restricted stock units (collectively, “Common Stock Equivalents”). The dilutive effect of Common Stock Equivalents is calculated under the treasury stock method using the average market price for the period. Certain Common Stock Equivalents were not included in the computation of diluted net income per common share because the exercise prices of those Common Stock Equivalents were greater than the average market price of the common shares. See Note 13 for the calculation of both basic and diluted net income per common share. 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. Trade Receivables Trade receivables consist primarily of amounts due to the Company from its normal business activities. In assessing the carrying value of its trade receivables, the Company estimates the recoverability by making assumptions based on factors such as current overall and industry-specific economic conditions, historical and anticipated customer performance, historical write-off and collection experience, the level of past-due amounts, and specific risks identified in the trade receivables portfolio. The following table summarizes the changes in the allowance for doubtful accounts: (thousands) 2016 2015 2014 Balance at January 1 $ 150 $ 175 $ 225 Provisions made during the year 415 471 137 Write-offs (473 ) (497 ) (193 ) Recoveries during the year — 1 6 Balance at December 31 $ 92 $ 150 $ 175 Inventories Inventories are stated at the lower of cost (First-In, First-Out (FIFO) Method) and net realizable value. Based on the inventory aging and other considerations for realizable value, the Company writes down the carrying value to net realizable value where appropriate. The Company reviews inventory on-hand and records provisions for obsolete inventory based on current assessments of future demand, market conditions, and related management initiatives. Any significant unanticipated changes in demand could have a significant impact on the value of the Company’s inventory and operating results. The cost of manufactured inventories includes raw materials, inbound freight, labor and overhead. The Company’s distribution inventories include the cost of raw materials and inbound freight. Property, Plant and Equipment Property, plant and equipment (“PP&E”) is generally recorded at cost. However, PP&E acquired in connection with an acquisition is recorded at fair value. Depreciation is computed primarily by the straight-line method applied to individual items based on estimated useful lives, which generally range from 10 to 30 years for buildings and improvements, and from three to seven years for machinery, equipment and transportation equipment. Leasehold improvements are amortized over the lesser of their useful lives or the related lease term. When properties are retired or disposed, the costs and accumulated depreciation are eliminated and the resulting profit or loss is recognized in the results of operations. Long-lived assets other than goodwill and intangible assets that are held for sale are recorded at the lower of the carrying value or the fair market value less the estimated cost to sell. The recoverability of PP&E is evaluated whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, primarily based on estimated selling price, appraised value or projected future cash flows. Goodwill and Other Intangible Assets Assets and liabilities acquired in business combinations are accounted for using the purchase method and are recorded at their respective fair values. Upon acquisition, goodwill and other intangible assets are assigned to reporting units which are one level below the Company’s business segments. Goodwill and indefinite-lived intangible assets are not amortized but are subject to an annual (or under certain circumstances more frequent) impairment test based on their estimated fair value. The Company performs the required test for goodwill and indefinite-lived intangible assets impairment in the fourth quarter, or more frequently, if events or changes in circumstances indicate that the carrying value may exceed the fair value. Finite-lived intangible assets relate to customer relationships and non-compete agreements. Finite-lived intangible assets that meet certain criteria continue to be amortized over their useful lives and are also subject to an impairment test based on estimated undiscounted cash flows when impairment indicators exist. Intangible assets acquired in business combinations are initially recorded at their estimated fair values as determined by an income valuation approach using Level III fair value inputs. There was no impairment for goodwill and other intangible assets for the years ended December 31, 2016 , 2015 and 2014 . Impairment of Long-Lived Assets When events or conditions warrant, the Company evaluates the recoverability of long-lived assets other than goodwill and indefinite-lived intangible assets and considers whether these assets are impaired. The Company assesses the recoverability of these assets based upon several factors, including management's intention with respect to the assets and their projected future undiscounted cash flows. If projected undiscounted cash flows are less than the carrying amount of the assets, the Company adjusts the carrying amounts of such assets to their estimated fair value. A significant adverse change in the Company’s business climate in future periods could result in a significant loss of market share or the inability to achieve previously projected revenue growth and could lead to a required assessment of the recoverability of the Company’s long-lived assets, which may subsequently result in an impairment charge. Deferred Financing Costs Deferred financing costs are classified as non-current assets on the statement of financial position and are amortized over the life of the related debt or credit facility using the straight-line method. The consolidated statements of financial position at December 31, 2016 and 2015 reflect the reclassification of assets related to deferred financing costs associated with the Term Loan (as defined herein) outstanding under the Company's 2015 Credit Facility (as defined herein) that were reclassified and presented net of long-term debt outstanding. The classification is the result of the Company's adoption of a new accounting standard that requires debt issuance costs be presented in the statement of financial position as a reduction in the carrying amount of debt, consistent with the presentation of debt issuance discounts. The deferred financing costs related to the 2015 Revolver (as defined herein) were not reclassified to long-term debt and are reflected as a component of non-current assets on the consolidated statements of financial position for the periods presented because the standard does not apply to line-of-credit arrangements. In the first quarter of 2016, the Company adopted this accounting standard as required on a retroactive basis. At December 31, 2015 , the total maximum borrowing limit under the Company's 2015 Credit Facility was $300.0 million , of which $75.0 million or 25% represented the total commitment under the Term Loan and was the basis for allocating a portion of the deferred financing costs to the Term Loan. Unamortized total deferred financing costs were $2.5 million at December 31, 2015, of which $0.6 million was allocated to the Term Loan. Financial Instruments The Company’s financial instruments consist principally of cash and cash equivalents, trade receivables, debt and accounts payable. The Company believes cash and cash equivalents, trade receivables, and accounts payable are recorded at amounts that approximate their current market values because of the relatively short maturities of these financial instruments. The carrying value of the long-term debt instruments approximates the fair value based upon terms and conditions available to the Company in comparison to the terms and conditions of the outstanding debt. Income Taxes Deferred taxes are provided on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss carry-forwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are recognized in the current year to the extent future deferred tax liability timing differences are expected to reverse. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets may not be realized. The Company reports a liability, if any, for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

RECENTLY ISSUED ACCOUNTING PRON

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	12 Months Ended

Accounting Policies [Abstract]
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard which specifies how and when to recognize revenue as well as providing informative, relevant disclosures. In August 2015, the FASB deferred the effective date of this standard by one year, which would become effective for fiscal years beginning after December 15, 2017. Based on an evaluation and review of its current accounting policies and practices related to the recognition of revenue, the Company does not anticipate that the adoption of this new accounting standard will have a material impact on the consolidated statements or operations, financial position or cash flows. The Company expects to adopt this standard as of January 1, 2018, under the modified retrospective method where the cumulative effect is recognized at the date of initial application. Debt Financing / Debt Issuance Costs In April 2015, the FASB issued a new accounting standard that requires debt issuance costs be presented in the statement of financial position as a reduction in the carrying amount of debt, consistent with the presentation of debt issuance discounts. The Company adopted this new standard, on a retroactive basis, in the first quarter of 2016 as required. Total assets and total liabilities on the Company’s consolidated statement of financial position as of December 31, 2015 were reduced by the reclassification of $0.6 million of deferred financing costs related to the Term Loan to the long-term debt, less current maturities, net line on the consolidated statement of financial position. Income Taxes In November 2015, the FASB issued a new accounting standard that simplifies the presentation of deferred income taxes. Under the new standard, deferred tax assets and liabilities are required to be classified, on a net basis, as noncurrent on the consolidated statement of financial position. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. During the first quarter of 2016, the Company elected to adopt this standard, thus reclassifying current deferred tax assets to noncurrent, net of deferred tax liabilities, on the consolidated statements of financial position. The prior year reporting period was retroactively adjusted. Current assets on the Company’s consolidated statement of financial position as of December 31, 2015 were reduced by the reclassification of $5.8 million of current deferred tax assets to long-term deferred tax assets. Total assets and total liabilities on the Company’s consolidated statement of financial position as of December 31, 2015 were reduced by the reclassification of $3.8 million of long-term deferred tax liabilities to long-term deferred tax assets. The adoption of this standard had no impact on the Company’s consolidated statements of income. See Note 10 for additional details. Leases In February 2016, the FASB issued a new accounting standard that will require that an entity recognize lease assets and lease liabilities on its balance sheet for leases in excess of one year that were previously classified as operating leases under U.S. GAAP. The standard also requires companies to disclose in the footnotes to the financial statements information about the amount, timing, and uncertainty for the payments made for the lease agreements. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2018 on a retroactive basis. Early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its consolidated financial statements. Stock Compensation In March 2016, the FASB issued a new accounting standard for share-based payments relating to: (i) the income tax consequences related to exercised or vested share-based payment awards; (ii) the classification of awards as assets or liabilities; and (iii) the classification in the consolidated statements of cash flows. In addition, the standard provides an accounting policy election to account for forfeitures as they occur. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. The Company elected to early adopt the requirements of this accounting standard in the fourth quarter of 2016 and retroactively reflected the impact of the adoption in its financial statements effective January 1, 2016 as required under the standard. Specifically, the excess tax benefits related to the settlement of share-based compensation that were realized in 2016, and previously recorded in additional paid-in capital, were reclassified as a reduction to income tax expense on the consolidated statement of income for the year ended December 31, 2016. See Note 18 for the impact of the reclassification to the Company's previously reported net income and net income per basic and diluted share calculations for the first three quarters of 2016. In addition, as required under the new standard, cash paid by directly withholding shares for tax withholding purposes of $1.2 million and $0.6 million was reclassified from operating activities to financing activities in the consolidated statements of cash flows for the years ended December 31, 2015 and 2014, respectively. Furthermore, the Company elected to change its accounting policy to account for forfeitures for share-based awards when they occur. Cash Flow Statement Classifications In August 2016, the FASB issued a new accounting standard related to the classification of certain cash receipts and cash payments in the statement of cash flows. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company anticipates adopting the new standard as of January 1, 2018 as required and has determined that the implementation of it will have no impact on its consolidated statements of cash flows for the periods presented. Goodwill Impairment In January 2017, the FASB issued a new accounting standard that simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The standard requires that the impairment loss be measured as the excess of the reporting unit's carrying amount over its fair value. It eliminates the second step that requires the impairment to be measured between the implied value of a reporting unit's goodwill with its carrying value. The standard is effective for annual and any interim impairment tests for periods beginning after December 15, 2019 and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its consolidated financial statements. Definition of a Business In January 2017, the FASB issued a new accounting standard that clarifies the definition of a business. This standard will assist companies in interpreting the definition of a business which may affect certain areas of accounting including acquisitions, disposals, goodwill and consolidation. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its consolidated financial statements.

ACQUISITIONS	ACQUISITIONS General The Company completed a total of 14 acquisitions involving 19 companies in the three years ended December 31, 2016 , 2015 and 2014 as discussed below. Each of the acquisitions was funded through borrowings under the Company’s credit facility in existence at the time of acquisition. Assets acquired and liabilities assumed in the individual acquisitions were recorded on the Company’s consolidated statements of financial position at their estimated fair values as of the respective dates of acquisition. In general, the acquisitions described below provided the opportunity for the Company to either establish a new presence in a particular market and/or expand its product offerings in an existing market and increase its market share and per unit content. For each acquisition, the excess of the purchase consideration over the fair value of the net assets acquired was recorded as goodwill, which represents the value of leveraging the Company’s existing purchasing, manufacturing, sales, and systems resources with the organizational talent and expertise of the acquired companies’ respective management teams to maximize efficiencies, revenue impact, market share growth, and net income. The goodwill recognized is expected to be deductible for income tax purposes for each of the 2014, 2015 and 2016 acquisitions with the exception of the BH Electronics, Inc. acquisition. Intangible asset values were estimated using income based valuation methodologies. The disclosure of the amortization periods assigned to finite-lived intangible assets is more fully disclosed in Note 7.

Income tax expense is the tax payable or refundable for the current period plus or minus the change in deferred tax assets and liabilities during the period. In March 2016, the FASB issued a new accounting standard for share-based payment awards, which simplifies (i) the income tax consequences related to exercised or vested share-based payment awards; (ii) the classification of awards as assets or liabilities; and (iii) the classification in the consolidated statements of cash flows. In addition, the standard provides an accounting policy election to account for forfeitures as they occur. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. The Company elected to early adopt the requirements of this accounting standard in the fourth quarter of 2016 and retroactively reflected the impact of the adoption in its financial statements effective January 1, 2016 as required under the standard. Specifically, the excess tax benefits related to the settlement of share-based compensation that were realized in 2016, and previously recorded in additional paid-in capital, were reclassified as a reduction to income tax expense on the consolidated statement of income for the year ended December 31, 2016. See Note 18 for the impact of the reclassification to the Company's previously reported net income and net income per basic and diluted share calculations for the first three quarters of 2016. In 2016 and 2015, the Company realized approximately $3.2 million and $2.9 million , respectively, of additional taxable deductions related to excess tax benefits on share-based compensation, which had not been recorded as deferred tax assets at December 31, 2015 and 2014. In 2016, these tax benefits were recorded as a reduction to income tax expense upon realization in relation to the adoption of the share-based payment awards accounting standard. In 2015, the tax benefits were recorded to additional paid-in-capital upon realization as required under the previous accounting standard. The composition of the deferred tax assets and liabilities as of December 31, 2016 and 2015 is as follows: (thousands) 2016 2015 Long-term deferred income tax assets (liabilities): Trade receivables allowance $ 36 $ 59 Inventory capitalization 1,142 890 Accrued expenses 4,248 4,153 Deferred compensation 701 794 Inventory reserves 1,501 1,211 State NOL Carryforwards 13 30 Share based compensation 3,983 2,434 Pension liability 13 12 Intangibles (9,467 ) (473 ) Depreciation expense (6,658 ) (5,151 ) Prepaid expenses (500 ) (1,955 ) Deferred tax assets (liabilities), net $ (4,988 ) $ 2,004 In November 2015, the FASB issued a new accounting standard that simplifies the presentation of deferred income taxes. Under the new standard, deferred tax assets and liabilities are required to be classified, on a net basis, as noncurrent on the consolidated statement of financial position. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. During the first quarter of 2016, the Company elected to adopt this standard, thus reclassifying current deferred tax assets to noncurrent, net of deferred tax liabilities, on the consolidated statements of financial position. The prior year reporting period was retroactively adjusted. Current assets on the Company’s consolidated statement of financial position as of December 31, 2015 were reduced by the reclassification of $5.8 million of current deferred tax assets to long-term deferred tax assets. Total assets and total liabilities on the Company’s consolidated statements of financial position as of December 31, 2015 were reduced by the reclassification of $3.8 million of long-term deferred tax liabilities to long-term deferred tax assets. The adoption of this standard had no impact on the Company’s consolidated statements of income. The Company paid income taxes of $29.2 million , $24.1 million and $16.7 million in 2016 , 2015 and 2014 , respectively. The Company did not reflect any unrecognized tax benefits in its financial statements as of December 31, 2016 or December 31, 2015 and does not expect any significant changes relating to unrecognized tax benefits in the 12 months following December 31, 2016 . The Company is subject to periodic audits by domestic tax authorities. For the majority of tax jurisdictions, the U.S. federal statute of limitations remains open for the years 2013 and later. The Company is currently under audit by the State of Indiana for tax years 2012, 2013 and 2014.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company has determined that its reportable segments are those based on its method of internal reporting, which segregates its businesses by product category and production or distribution process. A description of the Company’s reportable segments is as follows: Manufacturing – This segment includes the following divisions: laminated products that are utilized to produce furniture, shelving, walls, countertops, and cabinet products, cabinet doors, fiberglass bath fixtures, hardwood furniture, vinyl printing, solid surface, granite, and quartz countertop fabrication, RV painting, fabricated aluminum products, fiberglass and plastic components, softwoods lumber, custom cabinetry, polymer-based flooring, electrical systems components, and other products. Patrick’s major manufactured products also include wrapped vinyl, paper and hardwood profile mouldings, interior passage doors, slide-out trim and fascia, and slotwall panels and components. The Manufacturing segment contributed approximately 82% , 78% and 75% of the Company’s net sales for the years ended December 31, 2016 , 2015 and 2014 , respectively. Distribution – The Company distributes pre-finished wall and ceiling panels, drywall and drywall finishing products, electronics and audio systems components, wiring, electrical and plumbing products, fiber reinforced polyester products, cement siding, interior passage doors, roofing products, laminate and ceramic flooring, shower doors, furniture, fireplaces and surrounds, interior and exterior lighting products, and other miscellaneous products. The Distribution segment contributed approximately 18% , 22% and 25% of the Company’s net sales for the years ended December 31, 2016 , 2015 and 2014 , respectively. The accounting policies of the segments are the same as those described in Note 2, except that segment data includes intersegment sales. Assets are identified to the segments with the exception of cash, prepaid expenses, land and buildings, and certain deferred assets, which are identified with the corporate division. The corporate division charges rents to the segments for use of the land and buildings based upon estimated market rates. The Company accounts for intersegment sales similar to third party transactions, which reflect current market prices. The Company also records certain income from purchase incentive agreements as corporate division revenue. The Company evaluates the performance of its segments and allocates resources to them based on a variety of indicators including sales, cost of goods sold, operating income, depreciation and amortization, and total identifiable assets as presented in the tables below.d The tables below present information about the operating income, segment assets, and certain other items that are either used by or provided to the chief operating decision maker of the Company as of and for the years ended December 31, 2016 , 2015 and 2014 (in thousands): 2016 Manufacturing Distribution Total Net outside sales $ 997,205 $ 224,682 $ 1,221,887 Intersegment sales 23,187 2,898 26,085 Total sales 1,020,392 227,580 1,247,972 Cost of goods sold 853,596 189,263 1,042,859 Operating income 107,105 15,001 122,106 Identifiable assets 421,203 61,725 482,928 Depreciation and amortization 18,553 3,102 21,655 2015 Manufacturing Distribution Total Net outside sales $ 720,411 $ 199,922 $ 920,333 Intersegment sales 17,964 2,565 20,529 Total sales 738,375 202,487 940,862 Cost of goods sold 616,038 170,886 786,924 Operating income 78,582 12,790 91,372 Identifiable assets 300,305 51,677 351,982 Depreciation and amortization 12,676 1,987 14,663 2014 Manufacturing Distribution Total Net outside sales $ 548,796 $ 186,921 $ 735,717 Intersegment sales 18,356 2,517 20,873 Total sales 567,152 189,438 756,590 Cost of goods sold 477,189 160,375 637,564 Operating income 55,838 10,659 66,497 Identifiable assets 167,278 50,869 218,147 Depreciation and amortization 7,087 1,560 8,647 Consolidated net sales by product type were as follows for the years ended December 31, 2016, 2015 and 2014: (thousands) 2016 2015 2014 Decorative interior products and components $ 982,213 $ 733,830 $ 615,285 Non-decorative interior products and components 75,406 59,436 54,025 Exterior products and other 164,268 127,067 66,407 Consolidated net sales $ 1,221,887 $ 920,333 $ 735,717 A reconciliation of certain line items pertaining to the total reportable segments to the consolidated financial statements as of and for the years ended December 31, 2016 , 2015 and 2014 is as follows (in thousands): 2016 2015 2014 Net sales: Total sales for reportable segments $ 1,247,972 $ 940,862 $ 756,590 Elimination of intersegment sales (26,085 ) (20,529 ) (20,873 ) Consolidated net sales $ 1,221,887 $ 920,333 $ 735,717 Cost of goods sold: Total cost of goods sold for reportable segments $ 1,042,859 $ 786,924 $ 637,564 Elimination of intersegment cost of goods sold (26,085 ) (20,529 ) (20,873 ) Other 2,644 1,659 523 Consolidated cost of goods sold $ 1,019,418 $ 768,054 $ 617,214 Operating income: Operating income for reportable segments $ 122,106 $ 91,372 $ 66,497 Unallocated corporate expenses (17,901 ) (12,667 ) (10,549 ) Amortization (13,368 ) (8,787 ) (4,477 ) Consolidated operating income $ 90,837 $ 69,918 $ 51,471 Consolidated total assets: Identifiable assets for reportable segments $ 482,928 $ 351,982 $ 218,147 Corporate property and equipment 38,550 23,611 24,854 Current and long-term assets not allocated to segments 10,630 4,838 8,602 Intangibles and other assets not allocated to segments 2,842 3,068 3,958 Consolidated total assets $ 534,950 $ 381,584 $ 255,561 Depreciation and amortization: Depreciation and amortization for reportable segments $ 21,655 $ 14,663 $ 8,647 Corporate depreciation and amortization 2,707 2,112 1,786 Consolidated depreciation and amortization $ 24,362 $ 16,775 $ 10,433 Amortization expense related to intangible assets in the Manufacturing segment for the years ended December 31, 2016 , 2015 and 2014 was $ 10.6 million , $ 7.1 million and $ 3.2 million , respectively.

QUARTERLY FINANCIAL DATA (UNAUDITED)	QUARTERLY FINANCIAL DATA (UNAUDITED) Selected quarterly financial data for the years ended December 31, 2016 and 2015 is as follows: (thousands except per share data) 1Q 2Q 3Q 4Q 2016 Net sales $ 278,637 $ 315,163 $ 304,151 $ 323,936 $ 1,221,887 Gross profit 45,352 55,284 48,852 52,981 202,469 Net income (1) 12,975 16,969 12,073 13,560 55,577 Net income per common share (1) (2): Basic $ 0.87 $ 1.13 $ 0.80 $ 0.90 $ 3.70 Diluted 0.85 1.11 0.79 0.89 3.64 (thousands except per share data) 1Q 2Q 3Q 4Q 2015 Net sales $ 223,388 $ 233,481 $ 214,805 $ 248,659 $ 920,333 Gross profit 35,394 40,393 35,041 41,451 152,279 Net income 9,150 12,073 8,960 12,036 42,219 Net income per common share (2): Basic $ 0.60 $ 0.79 $ 0.58 $ 0.79 $ 2.76 Diluted 0.59 0.78 0.58 0.78 2.72 (1) The first three quarters of 2016 reflect the retroactive adjustment to net income and the related basic and diluted per share amounts which resulted from the Company's adoption of the share-based compensation accounting standard in the fourth quarter of 2016. See "Stock Compensation" in Note 3 for additional details. (2) Basic and diluted net income per common share are computed independently for each of the quarters presented. Therefore, the sum of quarterly basic and diluted net income per common share information may not equal annual basic and diluted net income per common share. The adoption of the new accounting standard resulted in the retroactive recognition of $1.3 million of excess tax benefits in the Company's provision for income taxes rather than in additional paid-in capital during the first three quarters of 2016 and impacted the previously reported quarterly results for the first three quarters of 2016 as follows: Quarter ended Quarter ended Quarter ended Mar 27, 2016 Jun 26, 2016 Sep 25, 2016 (thousands except per share data) As reported As adjusted As reported As adjusted As reported As adjusted Income statements: Provision for income taxes $ 6,932 $ 5,990 $ 9,672 $ 9,406 $ 6,175 $ 6,127 Net income $ 12,033 $ 12,975 $ 16,703 $ 16,969 $ 12,025 $ 12,073 Basic earnings per share $ 0.81 $ 0.87 $ 1.11 $ 1.13 $ 0.80 $ 0.80 Diluted earnings per share $ 0.80 $ 0.85 $ 1.10 $ 1.11 $ 0.79 $ 0.79 Diluted weighted average shares outstanding 15,130 15,192 15,176 15,231 15,235 15,308

SUMMARY OF SIGNIFICANT ACCOUN28

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition The Company ships product based on specific orders from customers and revenue is recognized at the time of passage of title and risk of loss to the customer, which is generally upon delivery. The Company’s selling price is fixed and determined at the time of shipment and collectability is reasonably assured and not contingent upon the customer’s use or resale of the product. The Company records freight billed to customers in net sales. The corresponding costs incurred for shipping and handling related to these customer billed freight costs are recorded in warehouse and delivery expenses and aggregated $1.4 million , $1.1 million and $0.9 million for 2016 , 2015 and 2014 , respectively. Estimated costs related to customer volume rebates and sales incentives are accrued as a reduction of revenue at the time products are sold .
Costs and Expenses	Costs and Expenses Cost of goods sold includes material costs, direct and indirect labor, overhead expenses, inbound freight charges, inspection costs, internal transfer costs, receiving costs, and other costs. Warehouse and delivery expenses include salaries and wages, building rent and insurance, and other overhead costs related to distribution operations and delivery costs related to the shipment of finished and distributed products to customers. Purchasing costs are included in selling, general and administrative (“SG&A”) expenses.
Share Based Compensation	Stock Based Compensation Compensation expense related to the fair value of stock awards as of the grant date is calculated based on the Company’s closing stock price on the date of grant. In addition, the Company estimates the fair value of all stock option and stock appreciation rights ("SARS") awards as of the grant date by applying the Black-Scholes option-pricing model. The use of this valuation model involves assumptions that are judgmental and highly sensitive in the determination of compensation expense and include the dividend yield and exercise price. Expected volatilities take into consideration the historical volatility of the Company’s common stock. The expected term of options and SARS represents the period of time that the options and SARS granted are expected to be outstanding based on historical Company trends. The risk free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for instruments of a similar term.
Income Per Common Share	Income Per Common Share Basic net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding, plus the dilutive effect of stock options, stock appreciation rights, and restricted stock units (collectively, “Common Stock Equivalents”). The dilutive effect of Common Stock Equivalents is calculated under the treasury stock method using the average market price for the period. Certain Common Stock Equivalents were not included in the computation of diluted net income per common share because the exercise prices of those Common Stock Equivalents were greater than the average market price of the common shares. See Note 13 for the calculation of both basic and diluted net income per common share.
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.
Trade Receivables	Trade Receivables Trade receivables consist primarily of amounts due to the Company from its normal business activities. In assessing the carrying value of its trade receivables, the Company estimates the recoverability by making assumptions based on factors such as current overall and industry-specific economic conditions, historical and anticipated customer performance, historical write-off and collection experience, the level of past-due amounts, and specific risks identified in the trade receivables portfolio.
Inventories	Inventories Inventories are stated at the lower of cost (First-In, First-Out (FIFO) Method) and net realizable value. Based on the inventory aging and other considerations for realizable value, the Company writes down the carrying value to net realizable value where appropriate. The Company reviews inventory on-hand and records provisions for obsolete inventory based on current assessments of future demand, market conditions, and related management initiatives. Any significant unanticipated changes in demand could have a significant impact on the value of the Company’s inventory and operating results. The cost of manufactured inventories includes raw materials, inbound freight, labor and overhead. The Company’s distribution inventories include the cost of raw materials and inbound freight.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment (“PP&E”) is generally recorded at cost. However, PP&E acquired in connection with an acquisition is recorded at fair value. Depreciation is computed primarily by the straight-line method applied to individual items based on estimated useful lives, which generally range from 10 to 30 years for buildings and improvements, and from three to seven years for machinery, equipment and transportation equipment. Leasehold improvements are amortized over the lesser of their useful lives or the related lease term. When properties are retired or disposed, the costs and accumulated depreciation are eliminated and the resulting profit or loss is recognized in the results of operations. Long-lived assets other than goodwill and intangible assets that are held for sale are recorded at the lower of the carrying value or the fair market value less the estimated cost to sell. The recoverability of PP&E is evaluated whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, primarily based on estimated selling price, appraised value or projected future cash flows.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Assets and liabilities acquired in business combinations are accounted for using the purchase method and are recorded at their respective fair values. Upon acquisition, goodwill and other intangible assets are assigned to reporting units which are one level below the Company’s business segments. Goodwill and indefinite-lived intangible assets are not amortized but are subject to an annual (or under certain circumstances more frequent) impairment test based on their estimated fair value. The Company performs the required test for goodwill and indefinite-lived intangible assets impairment in the fourth quarter, or more frequently, if events or changes in circumstances indicate that the carrying value may exceed the fair value. Finite-lived intangible assets relate to customer relationships and non-compete agreements. Finite-lived intangible assets that meet certain criteria continue to be amortized over their useful lives and are also subject to an impairment test based on estimated undiscounted cash flows when impairment indicators exist. Intangible assets acquired in business combinations are initially recorded at their estimated fair values as determined by an income valuation approach using Level III fair value inputs.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets When events or conditions warrant, the Company evaluates the recoverability of long-lived assets other than goodwill and indefinite-lived intangible assets and considers whether these assets are impaired. The Company assesses the recoverability of these assets based upon several factors, including management's intention with respect to the assets and their projected future undiscounted cash flows. If projected undiscounted cash flows are less than the carrying amount of the assets, the Company adjusts the carrying amounts of such assets to their estimated fair value. A significant adverse change in the Company’s business climate in future periods could result in a significant loss of market share or the inability to achieve previously projected revenue growth and could lead to a required assessment of the recoverability of the Company’s long-lived assets, which may subsequently result in an impairment charge.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are classified as non-current assets on the statement of financial position and are amortized over the life of the related debt or credit facility using the straight-line method.
Financial Instruments	Financial Instruments The Company’s financial instruments consist principally of cash and cash equivalents, trade receivables, debt and accounts payable. The Company believes cash and cash equivalents, trade receivables, and accounts payable are recorded at amounts that approximate their current market values because of the relatively short maturities of these financial instruments. The carrying value of the long-term debt instruments approximates the fair value based upon terms and conditions available to the Company in comparison to the terms and conditions of the outstanding debt.
Income Taxes	Income Taxes Deferred taxes are provided on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss carry-forwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are recognized in the current year to the extent future deferred tax liability timing differences are expected to reverse. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets may not be realized. The Company reports a liability, if any, for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.
Recent Accounting Pronouncements	Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard which specifies how and when to recognize revenue as well as providing informative, relevant disclosures. In August 2015, the FASB deferred the effective date of this standard by one year, which would become effective for fiscal years beginning after December 15, 2017. Based on an evaluation and review of its current accounting policies and practices related to the recognition of revenue, the Company does not anticipate that the adoption of this new accounting standard will have a material impact on the consolidated statements or operations, financial position or cash flows. The Company expects to adopt this standard as of January 1, 2018, under the modified retrospective method where the cumulative effect is recognized at the date of initial application. Debt Financing / Debt Issuance Costs In April 2015, the FASB issued a new accounting standard that requires debt issuance costs be presented in the statement of financial position as a reduction in the carrying amount of debt, consistent with the presentation of debt issuance discounts. The Company adopted this new standard, on a retroactive basis, in the first quarter of 2016 as required. Total assets and total liabilities on the Company’s consolidated statement of financial position as of December 31, 2015 were reduced by the reclassification of $0.6 million of deferred financing costs related to the Term Loan to the long-term debt, less current maturities, net line on the consolidated statement of financial position. Income Taxes In November 2015, the FASB issued a new accounting standard that simplifies the presentation of deferred income taxes. Under the new standard, deferred tax assets and liabilities are required to be classified, on a net basis, as noncurrent on the consolidated statement of financial position. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. During the first quarter of 2016, the Company elected to adopt this standard, thus reclassifying current deferred tax assets to noncurrent, net of deferred tax liabilities, on the consolidated statements of financial position. The prior year reporting period was retroactively adjusted. Current assets on the Company’s consolidated statement of financial position as of December 31, 2015 were reduced by the reclassification of $5.8 million of current deferred tax assets to long-term deferred tax assets. Total assets and total liabilities on the Company’s consolidated statement of financial position as of December 31, 2015 were reduced by the reclassification of $3.8 million of long-term deferred tax liabilities to long-term deferred tax assets. The adoption of this standard had no impact on the Company’s consolidated statements of income. See Note 10 for additional details. Leases In February 2016, the FASB issued a new accounting standard that will require that an entity recognize lease assets and lease liabilities on its balance sheet for leases in excess of one year that were previously classified as operating leases under U.S. GAAP. The standard also requires companies to disclose in the footnotes to the financial statements information about the amount, timing, and uncertainty for the payments made for the lease agreements. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2018 on a retroactive basis. Early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its consolidated financial statements. Stock Compensation In March 2016, the FASB issued a new accounting standard for share-based payments relating to: (i) the income tax consequences related to exercised or vested share-based payment awards; (ii) the classification of awards as assets or liabilities; and (iii) the classification in the consolidated statements of cash flows. In addition, the standard provides an accounting policy election to account for forfeitures as they occur. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2016 and early adoption is permitted. The Company elected to early adopt the requirements of this accounting standard in the fourth quarter of 2016 and retroactively reflected the impact of the adoption in its financial statements effective January 1, 2016 as required under the standard. Specifically, the excess tax benefits related to the settlement of share-based compensation that were realized in 2016, and previously recorded in additional paid-in capital, were reclassified as a reduction to income tax expense on the consolidated statement of income for the year ended December 31, 2016. See Note 18 for the impact of the reclassification to the Company's previously reported net income and net income per basic and diluted share calculations for the first three quarters of 2016. In addition, as required under the new standard, cash paid by directly withholding shares for tax withholding purposes of $1.2 million and $0.6 million was reclassified from operating activities to financing activities in the consolidated statements of cash flows for the years ended December 31, 2015 and 2014, respectively. Furthermore, the Company elected to change its accounting policy to account for forfeitures for share-based awards when they occur. Cash Flow Statement Classifications In August 2016, the FASB issued a new accounting standard related to the classification of certain cash receipts and cash payments in the statement of cash flows. This standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company anticipates adopting the new standard as of January 1, 2018 as required and has determined that the implementation of it will have no impact on its consolidated statements of cash flows for the periods presented. Goodwill Impairment In January 2017, the FASB issued a new accounting standard that simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The standard requires that the impairment loss be measured as the excess of the reporting unit's carrying amount over its fair value. It eliminates the second step that requires the impairment to be measured between the implied value of a reporting unit's goodwill with its carrying value. The standard is effective for annual and any interim impairment tests for periods beginning after December 15, 2019 and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its consolidated financial statements. Definition of a Business In January 2017, the FASB issued a new accounting standard that clarifies the definition of a business. This standard will assist companies in interpreting the definition of a business which may affect certain areas of accounting including acquisitions, disposals, goodwill and consolidation. The standard is effective for financial statements issued for annual and interim periods beginning after December 15, 2017. The standard may be applied on a retrospective basis and early adoption is permitted. The Company is currently evaluating the effect of adopting this new accounting standard and has not yet determined the impact that the implementation of it will have on its consolidated financial statements.

See "Stock Compensation" in Note 3 for additional details. (2) Basic and diluted net income per common share are computed independently for each of the quarters presented. Therefore, the sum of quarterly basic and diluted net income per common share information may not equal annual basic and diluted net income per common share.
Schedule of changes in accounting principles	The adoption of the new accounting standard resulted in the retroactive recognition of $1.3 million of excess tax benefits in the Company's provision for income taxes rather than in additional paid-in capital during the first three quarters of 2016 and impacted the previously reported quarterly results for the first three quarters of 2016 as follows: Quarter ended Quarter ended Quarter ended Mar 27, 2016 Jun 26, 2016 Sep 25, 2016 (thousands except per share data) As reported As adjusted As reported As adjusted As reported As adjusted Income statements: Provision for income taxes $ 6,932 $ 5,990 $ 9,672 $ 9,406 $ 6,175 $ 6,127 Net income $ 12,033 $ 12,975 $ 16,703 $ 16,969 $ 12,025 $ 12,073 Basic earnings per share $ 0.81 $ 0.87 $ 1.11 $ 1.13 $ 0.80 $ 0.80 Diluted earnings per share $ 0.80 $ 0.85 $ 1.10 $ 1.11 $ 0.79 $ 0.79 Diluted weighted average shares outstanding 15,130 15,192 15,176 15,231 15,235 15,308
