SUMMARY OF SIGNIFICANT ACCOUNTING AND BUSINESS POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING AND BUSINESS POLICIES	NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING AND BUSINESS POLICIES Basis of Presentation The Company’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The accompanying consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and its variable interest entity (“VIE”). DXP is the primary beneficiary of a VIE in which DXP owns 47.5% of the equity. DXP consolidates the financial statements of the VIE with the financial statements of DXP. As of December 31, 2017, the total assets of the VIE were approximately $5.2 million including approximately $4.5 million of fixed assets. DXP is the primary customer of the VIE. Consolidation of the VIE increased cost of sales by approximately $0.6 million and $1.3 million for the twelve months ended December 31, 2017 and 2016, respectively. The Company recognized a related income tax benefit of $0.2 million and $0.3 million related to the VIE for the years ended December 31, 2017 and 2016, respectively. At December 31, 2017, the owners of the 52.5% of the equity not owned by DXP included employees of DXP. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation; none affected net income. Foreign Currency The financial statements of the Company’s Canadian subsidiaries are measured using local currencies as their functional currencies. Assets and liabilities are translated into U.S. dollars at current exchange rates, while income and expenses are translated at average exchange rates. Translation gains and losses are reported in other comprehensive income (loss). Gains and losses on transactions denominated in foreign currency are reported in consolidated statements of income (loss). Use of Estimates The preparation of financial statements in conformity with requires management to make estimates and assumptions in determining the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In the opinion of management, all adjustments necessary in order to make the financial statements not misleading have been included. Actual results could differ from those estimates. Cash and Cash Equivalents The Company’s presentation of cash includes cash equivalents. Cash equivalents are defined as short-term investments with maturity dates of 90 days or less at time of purchase. The Company places its cash and cash equivalents with institutions with high credit quality. However, at certain times, such cash and cash equivalents may be in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits. The Company has not historically experienced any losses when in excess of these limits. Receivables and Credit Risk Trade receivables consist primarily of uncollateralized customer obligations due under normal trade terms, which usually require payment within 30 days of the invoice date. However, these payment terms are extended in select cases and customers may not pay within stated trade terms. The Company has trade receivables from a diversified customer base located primarily in the Rocky Mountain, Northeastern, Midwestern, Southeastern and Southwestern regions of the United States, and Canada. The Company believes no significant concentration of credit risk exists. The Company evaluates the creditworthiness of its customers' financial positions and monitors accounts on a regular basis. Provisions to the allowance for doubtful accounts are made monthly and adjustments are made periodically (as circumstances warrant) based upon management’s best estimate of the collectability of such accounts. The Company writes off uncollectible trade accounts receivable when the accounts are determined to be uncollectible. No customer represents more than 10% of consolidated sales. Changes in this allowance for 2017, 2016 and 2015 were as follows ( in thousands Years Ended December 31, 2017 2016 2015 Balance at beginning of year $ 8,160 $ 9,364 $ 8,713 Charged to costs and expenses 3,367 180 2,014 Charged to other accounts 22 3 (17 ) 2 1,255 2 Deductions (2,534 ) 1 (1,367 ) 1 (2,618 ) 1 Balance at end of year $ 9,015 $ 8,160 $ 9,364 ( 1) Uncollectible accounts written off, net of recoveries (2) Includes allowance for doubtful accounts from acquisitions and divestiture (3) Primarily due to translation adjustments Fair Value of Financial Instruments The Company is required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. US GAAP establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. US GAAP prioritizes the inputs into three levels that may be used to measure fair value: Level 1 Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2 Level 2 applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Level 3 Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. See Note 4 for further information regarding the Company’s financial instruments. Inventories Inventories consist principally of finished goods and are priced at net realizable value Provisions Property and Equipment Property and equipment are carried on the basis of cost. Depreciation of property and equipment is computed using the straight-line method over their estimated useful lives. Maintenance and repairs of depreciable assets are charged against earnings as incurred. When properties are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and gains or losses are credited or charged to earnings. The principal estimated useful lives used in determining depreciation are as follows: Buildings 20-39 years Building improvements 10-20 years Furniture, fixtures and equipment 3-20 years Leasehold improvements Shorter of estimated useful life or related lease term Impairment of Goodwill and Other Intangible Assets The Company tests goodwill and other indefinite lived intangible assets for . The Company assigns the carrying value of these intangible assets to its "reporting units" and applies the test for goodwill at the reporting unit level. A reporting unit is defined as an operating segment or one level below a segment (a "component") if the component is a business and discrete information is prepared and reviewed regularly by segment management. The Company’s goodwill impairment assessment first permits evaluating qualitative factors to determine if a reporting unit's carrying value would more likely than not exceed its fair value. If the Company concludes, based on the qualitative assessment, that a reporting unit's carrying value would more likely than not exceed its fair value, the Company would perform a two-step quantitative test for that reporting unit. When a quantitative assessment is performed, the first step is to identify a potential impairment, and the second step measures the amount of the impairment loss, if any. Goodwill is deemed to be impaired if the carrying amount of a reporting unit’s goodwill exceeds its estimated fair value. During the third and fourth quarter of 2015, DXP performed interim impairment tests using a quantitative approach and recognized goodwill impairments of $57.8 million and $9.8 million, respectively. No impairment of goodwill was required in 2017 and 2016. Impairment of Long-Lived Assets, Excluding Goodwill The Company tests long-lived assets or asset groups for recoverability on an annual basis and when events or changes in circumstances indicate that their carrying amount may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed significantly before the end of its estimated useful life. Recoverability is assessed based on the carrying amount of the asset and its fair value which is generally determined based on the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset, as well as specific appraisal in certain instances. An impairment loss is recognized when the carrying amount is not recoverable and exceeds fair value. No impairment of long-lived assets excluding goodwill, was required in 2017, 2016 and 2015. Share-based Compensation The Company uses restricted stock for share-based compensation programs. The Company measures compensation cost with respect to equity instruments granted as stock-based payments to employees based upon the estimated fair value of the equity instruments at the date of the grant. The cost as measured is recognized as expense over the period which an employee is required to provide services in exchange for the award. Revenue Recognition For binding agreements to fabricate tangible assets to customer specifications, the Company recognizes revenues using the percentage of completion method. Under this method, revenues are recognized as costs are incurred and include estimated profits calculated on the basis of the relationship between costs incurred and total estimated costs at completion. If at any time expected costs exceed the value of the contract, the loss is recognized immediately. Revenues of approximately $40.6 million, $31.5 million, and $47.5 million were recognized on contracts in process for the years ended December 31, 2017, 2016, and 2015, respectively. The typical time span of these contracts is approximately one to two years. For other sales, the Company recognizes revenues when an agreement is in place, the price is fixed, title for product passes to the customer or services have been provided and collectability is reasonably assured, which is generally upon delivery to the customer. Revenues are recorded net of sales taxes. The Company reserves for potential customer returns based upon the historical level of returns. Shipping and Handling Costs The Company classifies shipping and handling charges billed to customers as sales. Shipping and handling charges paid to others are classified as a component of cost of sales. Self-insured Insurance and Medical Claims We generally retain up to $100,000 of risk for each claim for workers compensation, general liability, automobile and property loss. We accrue for the estimated loss on the self-insured portion of these claims. The accrual is adjusted quarterly based upon reported claims information. The actual cost could deviate from the recorded estimate. We generally retain up to $175,000 of risk on each medical claim for our employees and their dependents with the exception of less than 0.05% of employees where a higher risk is retained. We accrue for the estimated outstanding balance of unpaid medical claims for our employees and their dependents. The accrual is adjusted monthly based on recent claims experience. The actual claims could deviate from recent claims experience and be materially different from the reserve. The accrual for these claims at December 31, 2017 and 2016 was approximately $2.7 million and $3.1 million, respectively. Purchase Accounting DXP estimates the fair value of assets, including property, machinery and equipment and their related useful lives and salvage values, intangibles and liabilities when allocating the purchase price of an acquisition. The fair value estimates are developed using the best information available. Cost of Sales and Selling, General and Administrative Expense Cost of sales includes product and product related costs, inbound freight charges, internal transfer costs and depreciation. Selling, general and administrative expense includes purchasing and receiving costs, inspection costs, warehousing costs, depreciation and amortization. Debt Issuance Cost Amortization Fees paid to DXP’s lenders to secure a firm commitment on a term loan and revolving line of credit are presented as a direct deduction from the carrying amount of the debt liability. For the term loan, fees paid by DXP are amortized over the life of the loan as additional interest. Fees paid to secure a firm commitment from our lender on a revolving line of credit are amortized on a straight-line basis over the entire term of the arrangement. The total unamortized debt issuance costs reported on the consolidated balance sheets as of December 31, 2017 and 2016 was $10.1 million and $1.0 million, respectively. In connection with the extinguishment of the previously existing credit facility we recorded a $0.6 million write-off of debt issuance costs, which was included in interest expense during the third quarter of 2017. Income Taxes The Company utilizes the asset and liability method of accounting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and income tax bases of assets and liabilities. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to reverse. Valuation allowances are established to reduce deferred income tax assets to the amounts expected to be realized under a more likely than not criterion. Accounting for Uncertainty in Income Taxes A position taken or expected to be taken in a tax return is recognized in the financial statements when it is more likely than not (i.e. a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states. With few exceptions, the Company is no longer subject to U. S. federal, state and local tax examination by tax authorities for years prior to 2012. The Company's policy is to recognize interest related to unrecognized tax benefits as interest expense and penalties as operating expenses. The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter Comprehensive Income (Loss) Comprehensive income (loss) includes net income, foreign currency translation adjustments and unrealized gains and losses on certain investments in debt and equity securities. The Company’s other comprehensive (loss) income is comprised of changes in the market value of an investment with quoted market prices in an active market for identical instruments and translation adjustments from translating foreign subsidiaries to the reporting currency. Comprehensive income for the year ended December 31, 2016 was reduced by an $8.6 million charge recorded during the fourth quarter of 2016 to correct errors which accumulated during 2013, 2014 and 2015 due to the Company improperly recognizing an $8.6 million deferred tax asset on unrealized foreign currency losses not expected to be realized within one year. We assessed the materiality of this misstatement and concluded the misstatement was not material to the results of operations or financial condition for the years ended December 31, 2016 and 2015. Out-of-Period Items Deferred tax liabilities related to intangibles for customer relationships acquired in Canada during 2012 and 2013 were reduced by $2.2 million during the fourth quarter of 2017 to correct the tax rate used to establish the deferred tax liabilities at the dates of acquisition. The Company evaluated the misstatement of each period since these acquisitions were completed and concluded the effects were immaterial. During the first quarter of 2015, we identified a $2.5 million ($1.6 million net of tax) overstatement of an accrual at December 31, 2014, which overstated 2014 selling, general and administrative expense. We recorded an out-of-period adjustment to correct this overstatement in the quarter ended March 31, 2015. During the fourth quarter of 2015, we realized $1.5 million of net tax benefits related to events which occurred in earlier years. These out-of-period items reduced the 2015 net loss by $3.1 million and 2015 basic and diluted net loss per share by $0.21. We assessed the materiality of this overstatement and concluded the overstatement was not material to the results of operations or financial condition for the year ended December 31, 2015.

We have engaged third party consultants to assist us in assessing our contracts with customers, processes and controls required to address the impact that ASU No. 2014-09 will have on our business. The Company has elected the modified retrospective method and will adopt the new revenue guidance effective January 1, 2018, with an expected immaterial impact to the opening retained earnings. The analysis of contracts with customers under the new revenue recognition standard was consistent with the Company’s current revenue recognition model, whereby revenue is recognized primarily on the date products are shipped to the customer. The ASU also requires expanded qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, significant judgments and accounting policy. Based on our overall assessment performed to date, the adoption of the new standard is not expected to have an ongoing material impact on the Company’s Consolidated Financial Statements.

FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES [Abstract]
FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES	NOTE 4 - FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES Authoritative guidance for financial assets and liabilities measured on a recurring basis applies to all financial assets and financial liabilities that are being measured and reported on a fair value basis. Fair value, as defined in the authoritative guidance, is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. During the third and fourth quarters of 2015, in connection with interim tests for impairment, DXP recorded impairment charges of $57.8 million and $9.8 million, respectively, in order to reflect the implied fair values of goodwill, which is a non-recurring fair value adjustment. The fair values of goodwill used in the impairment calculations were estimated based on discounted estimated future cash flows with the discount rates of 10.0% to 11.5%. The measurements utilized to determine the implied fair value of goodwill represent significant unobservable inputs (Level 3) in accordance with the fair value hierarchy.

This decline in oil prices reduced spending by our customers and reduced our revenue expectations. This sustained decline in crude oil prices, reduced capital spending by customers and reduced revenue expectations were determined to be a triggering event during the third quarter of 2015. This triggering event required us to perform testing for possible goodwill impairment in two of our reporting units, and our step one testing indicated there was an impairment in the B27 IPS and B27 SC reporting units. No triggering event was identified in our other reporting units during the third quarter. ASC 350 step two of the goodwill impairment testing for the reporting units was performed preliminarily during the third quarter of 2015. Our preliminary analysis concluded that $48.0 million of our B27 IPS reporting unit’s goodwill and $9.8 million of our B27 SC reporting unit’s goodwill was impaired. The remaining goodwill for the B27 IPS and B27 SC reporting units at September 30, 2015 was $4.9 million and $10.3 million, respectively. The September 30, 2015 ASC 350 step two testing was completed in the fourth quarter of 2015 without any adjustment to the amount recorded in the third quarter of 2015. Fair value was based on expected future cash flow using Level 3 inputs under Account Standards Codification 820 Fair Value Measurements DXP recorded $1.1 million of impairment expense in the third quarter of 2015 to write off an acquired intangible asset related to an ITT Goulds distribution agreement, which was terminated by ITT Goulds during 2015. The remaining intangible asset value of vendor distribution agreements for the year ended December 31, 2015 was zero. None of the impairment is expected to be deductible for tax purposes. During the fourth quarter of 2015, the price of DXP’s common stock and the price of crude oil declined over 16% and over 18%, respectively. This decline in oil prices reduced spending by our customers during the fourth quarter and resulted in fourth quarter actual earnings for the B27 IPS and B27 SC reporting units declining significantly from the forecasts used in the impairment analysis at the end of the third quarter of 2015. The declines in forecasted earnings for these two reporting units were determined to be a triggering event during the fourth quarter of 2015. This triggering event required us to perform testing for possible goodwill impairment in these two reporting units, and our step one testing indicated there may be an impairment in the B27 IPS and B27 SC reporting units. No triggering event was identified in our other reporting units during the fourth quarter. ASC 350 step two of the goodwill impairment testing for the reporting units was performed during the fourth quarter of 2015. Our analysis concluded that $4.9 million of our B27 IPS reporting unit’s goodwill and $5.0 million of our B27 SC reporting unit’s goodwill was impaired. Fair value was based on expected future cash flow using Level 3 inputs under ASC 820. The cash flows are those expected to be generated by market participants, discounted at a rate of return market participants would expect. The remaining goodwill for the B27 IPS and B27 SC reporting units at December 31, 2015 was zero and $5.3 million, respectively. Approximately 60% of the goodwill associated with the B27 acquisition is not deductible for tax purposes. Accordingly, the financial statement tax benefit is calculated for only 40% of the goodwill impairment. The pretax impairment impacted DXP’s effective tax rate for 2015. After recording the fourth quarter impairment loss, accumulated impairment for the B27 IPS and B27 SC reporting units were $148.0 million and $25.0 million, respectively, for the year ended December 31, 2015. As none of the Company’s other reporting units recorded impairment losses in 2015, accumulated impairment for these units remained at $12.3 million. The impairment losses during the year ended December 31, 2015 are included in the “impairment expense” line item on the consolidated statements of income (loss).

The ABL Credit Agreement provides for asset-based revolving loans in an aggregate principal amount of up to $85.0 million (the “ABL Loans”). The ABL Loans may be increased, in increments of $10.0 million, up to an aggregate of $50.0 million. The facility will mature on August 29, 2022. Interest accrues on outstanding borrowings at a rate equal to LIBOR or CDOR plus a margin ranging from 1.25% to 1.75% per annum, or at an alternate base rate, Canadian prime rate or Canadian base rate plus a margin ranging from 0.25% to 0.75% per annum, in each case, based upon the average daily excess availability under the facility for the most recently completed calendar quarter. Fees ranging from 0.25% to 0.375% per annum are payable on the portion of the facility not in use at any given time. The interest rate for the ABL facility was 2.9% at December 31, 2017. The unused line fee was 0.375% at December 31, 2017. The obligations of the Borrowers are guaranteed by the Company and its direct and indirect material wholly-owned subsidiaries other than certain excluded subsidiaries. The ABL Credit Agreement contains a financial covenant restricting the Company from allowing its Fixed Charge Coverage Ratio be less than 1.00 to 1.00 during a compliance period, which is triggered when the availability under ABL facility falls below a threshold set forth in the ABL Credit Agreement. As of December 31, 2017, the Company's consolidated Fixed Charge Coverage Ratio was 3.67 to 1.00. The ABL Loan is secured by substantially all of the assets of the Company. Senior Secured Term Loan B: On August 29, 2017, DXP entered into a six year Senior Secured Term Loan B (the “Term Loan”) with an original principal amount of $250 million which amortizes in equal quarterly installments of 0.25% with the balance payable in August 2023, when the facility matures. Subject to securing additional lender commitments, the Term Loan allows for incremental increases in facility size up to an aggregate of $30 million, in minimum increments of $10 million, plus an additional amount such that DXP’s Secured Leverage Ratio (as defined under the Term Loan) would not exceed 3.60 to 1.00. We are required to repay the Term Loan in connection with certain asset sales and insurance proceeds, certain debt proceeds and 50% of excess cash flow, reducing to 25%, if our total leverage ratio is no more than 3.00 to 1.00 and 0%, if our total leverage ratio is no more than 2.50 to 1.00. In addition, the Term Loan contains a number of customary restrictive covenants. The interest rate for the Term Loan was 7.1 % as of December 31, 2017. The Term Loan requires that the company’s Secured Leverage Ratio, defined as the ratio, as of the last day of any fiscal quarter of consolidated secured debt (net of restricted cash, not to exceed $30 million) as of such day to EBITDA, beginning with the fiscal quarter ending December 31, 2017, is either equal to or less than as indicated in the table below: Fiscal Quarter Secured Leverage Ratio December 31, 2017 5.75:1.00 March 31, 2018 5.75:1.00 June 30, 2018 5.50:1.00 September 30, 2018 5.50:1.00 December 31, 2018 5.25:1.00 March 31, 2019 5.25:1.00 June 30, 2019 5.00:1.00 September 30, 2019 5.00:1.00 December 31, 2019 4.75:1.00 March 31, 2020 4.75:1.00 June 30, 2020 and each Fiscal Quarter thereafter 4.50:1.00 As of December 31, 2017, the Company's consolidated Secured Leverage Ratio was 3.59 to 1.00. The Term Loan is guaranteed by each of the Company’s direct and indirect material wholly owned subsidiaries, other than any of the Company’s Canadian subsidiaries and certain other excluded subsidiaries. The Term Loan is secured by substantially all of the assets of the Company. Extinguishment of Previously Existing Credit Facility As set forth above, on August 29, 2017, the Company terminated its previously existing credit agreement and facility and replaced it with the Term Loan and the ABL Credit Agreement. The terminated facility was under the Amended and Restated Credit Agreement, dated as of January 2, 2014, by and among the Company, as borrower, and Wells Fargo Bank, National Association, as issuing lender and administrative agent for other lenders (the “Original As of December 31, 2017, the maturities of long-term debt for the next five years and thereafter were as follows ( in thousands 2018 $ 3,381 2019 3,405 2020 3,436 2021 2,500 2022 2,500 Thereafter 236,875 Total $ 252,097

On December 22, 2017, the Tax Cuts and Jobs Act (“The Act”) was enacted into law. The majority of the provisions signed into law in 2017 do not take effect until January 1, 2018. The Act is a comprehensive tax reform legislation that contains significant changes to corporate taxation. Provisions on the enacted law include a permanent reduction of the corporate income tax rate from 35% to 21%, imposing a mandatory one-time tax on un-repatriated accumulated earnings of foreign subsidiaries, a partial limitation on the deductibility of business interest expense, a limitation on net operating losses to 80% of taxable income each year, a shift of the U.S. taxation of multinational corporations from a tax on worldwide income to a partial territorial system (along with rules that create a new U.S. minimum tax on earnings of foreign subsidiaries), and other related provisions to maintain the U.S. tax base. In accordance with SAB 118 issued by the Securities and Exchange Commission on December 22, 2017, companies are allowed a one year measurement period to complete the accounting related to The Act. Specifically, SAB 118 permits companies to record a provisional amount which can be remeasured during the measurement period due to obtaining, preparing, or analyzing additional information about facts and circumstances that existed as of the enacted date. As a result, we remeasured our net deferred income tax liabilities by a provisional $1.3 million benefit and a corresponding provisional decrease in the net deferred tax liability as of December 31, 2017. We are still in the process of analyzing The Act's impact as permitted under SAB 118. The largest impact to the Company being the remeasurement of deferred taxes due to the U.S. statutory tax rate change. The mandatory repatriation and resulting toll charge on accumulated foreign earnings and profits has limited impact on the Company as unremitted earnings from non-US jurisdictions is minimal. The Company is provisional in its approach and assertion that there is no financial statement impact as of December 31, 2017. Deferred tax liabilities related to intangibles for customer relationships acquired in Canada during 2012 and 2013 were reduced by $2.2 million during the fourth quarter of 2017 to correct the tax rate used to establish the deferred tax liabilities at the dates of acquisition. The Company evaluated the misstatement of each period since these acquisitions were completed and concluded the effects were immaterial. Total deferred tax assets at December 31, 2016 were reduced by an $8.6 million charge recorded during the fourth quarter of 2016 to correct errors of $1.3 million, $2.7 million and $4.6 million which were recorded during 2013, 2014 and 2015, respectively, due to the Company improperly recognizing a deferred tax asset related to cumulative translation adjustment losses. The Company evaluated the misstatement of each period and concluded the effects were immaterial. Therefore, the Company decided to correct the accumulated $8.6 million error in the fourth quarter of 2016. We assessed the materiality of this misstatement and concluded the misstatement was not material to the results of operations or financial condition for the years ended December 31, 2017, 2016 and 2015.

EARNINGS PER SHARE DATA [Abstract]
EARNINGS PER SHARE DATA	NOTE 12 - EARNINGS PER SHARE DATA Basic earnings per share is computed based on weighted average shares outstanding and excludes dilutive securities. Diluted earnings per share is computed including the impacts of all potentially dilutive securities. For the year ended December 31, 2015, we excluded the potential dilution of convertible preferred stock, which could be converted into 840,000 shares because they would be anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share for the periods indicated ( in thousands, except per share data December 31, 2017 2016 2015 Basic: Weighted average shares outstanding 17,400 15,042 14,423 Net income (loss) attributable to DXP Enterprises, Inc. $ 16,888 $ 7,702 $ (38,536 ) Convertible preferred stock dividend (90 ) (90 ) (90 ) Net income (loss) attributable to common shareholders $ 16,798 $ 7,612 $ (38,626 ) Per share amount $ 0.97 $ 0.51 $ (2.68 ) Diluted: Weighted average shares outstanding 17,400 15,042 14,423 Assumed conversion of convertible preferred stock 840 840 - Total dilutive shares 18,240 15,882 14,423 Net income (loss) attributable to common shareholders $ 16,798 $ 7,612 $ (38,626 ) Convertible preferred stock dividend 90 90 - Net income (loss) attributable to DXP Enterprises, Inc. for diluted earnings per share $ 16,888 $ 7,702 $ (38,626 ) Per share amount $ 0.93 $ 0.49 $ (2.68 ) Basic earnings per share have been computed by dividing net earnings by the weighted average number of common shares outstanding during the period and excludes dilutive securities. Diluted earnings per share reflects the potential dilution that could occur if the preferred stock was converted into common stock. Restricted stock is considered a participating security and is included in the computation of basic earnings per share as if vested. Because holders of Preferred Stock do not participate in losses, the loss was not allocated to Preferred Stock for fiscal year 2015. The Preferred Stock is convertible into 840,000 shares of common stock.

BUSINESS ACQUISITIONS [Abstract]
BUSINESS ACQUISITIONS	NOTE 14 - BUSINESS ACQUISITIONS All of the Company’s acquisitions have been accounted for using the purchase method of accounting. Revenues and expenses of the acquired businesses have been included in the accompanying consolidated financial statements beginning on their respective dates of acquisition. The allocation of purchase price to the acquired assets and liabilities is based on estimates of fair market value and may be revised if and when additional information the Company is awaiting concerning certain asset and liability valuations is obtained, provided that such information is received no later than one year after the date of acquisition. Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. It specifically includes the expected synergies and other benefits that we believe will result from combining the operations of our acquisitions with the operations of DXP and any intangible assets that do not qualify for separate recognition such as the assembled workforce. On April 1, 2015, the Company completed the acquisition of all of the equity interests of Tool Supply, Inc. (“TSI”) to expand DXP’s cutting tools offering in the Northwest region of the United States. DXP paid approximately $5.0 million for TSI, which was borrowed under the Company’s credit facility in effect at the date of acquisition. Estimated goodwill of $2.9 million and intangible assets of $2.0 were recognized for this acquisition. All of the estimated goodwill is included in the Service Centers segment. None of the estimated goodwill or intangible assets are expected to be tax deductible. On September 1, 2015, the Company completed the acquisition of all of the equity interests of Cortech Engineering, LLC (“Cortech”) to expand DXP’s rotating equipment offering to the Western seaboard. DXP paid approximately $14.9 million for Cortech. The purchase was financed with borrowings under the Company’s credit facility in effect at the date of acquisition, as well as by issuing $4.4 million (148.8 thousand shares) of DXP common stock. Estimated intangible assets of $5.2 were recognized for this acquisition. In the first quarter of 2016, DXP adjusted the deferred tax liability associated with the acquisition by $151 thousand, which resulted in an adjusted goodwill balance of $8.7 million. All of the estimated goodwill is included in the Service Centers segment. Approximately $4.5 million of the goodwill and intangible assets are not deductible for tax purposes. The value assigned to the non-compete agreements and customer relationships for business acquisitions were determined by discounting the estimated cash flows associated with non-compete agreements and customer relationships as of the date the acquisition was consummated. The estimated cash flows were based on estimated revenues net of operating expenses and net of capital charges for assets that contribute to the projected cash flow from these assets. The projected revenues and operating expenses were estimated based on management estimates. Net capital charges for assets that contribute to projected cash flow were based on the estimated fair value of those assets. For the twelve months ended December 31, 2016, businesses acquired during 2015 contributed sales of $25.2 million and earnings (loss) before taxes of approximately $(0.3) million. The pro forma unaudited results of operations for the Company on a consolidated basis for the twelve months ended December 31, 2017 and 2016, assuming the divestiture of a business completed in 2016 were consummated as of January 1, 2016 are as follows ( in millions, except per share amounts Years Ended December 31, 2017 2016 Net sales $ 1,006.8 $ 939.4 Net income attributable to DXP Enterprises, Inc. $ 16.9 $ 5.5 Per share data Basic earnings $ 0.97 $ 0.36 Diluted earnings $ 0.93 $ 0.35 The pro forma unaudited results of operations for the Company on a consolidated basis for the twelve months ended December 31, 2016 and 2015, assuming the acquisition of businesses completed in 2015 and divestiture of a business completed in 2016 (previously discussed in Item 1, Business in millions, except per share amounts Years Ended December 31, 2016 2015 Net sales $ 939.4 $ 1,228.9 Net income (loss) attributable to DXP Enterprises, Inc. $ 5.5 $ (40.7 ) Per share data Basic earnings (loss) $ 0.36 $ (2.83 ) Diluted earnings (loss) $ 0.35 $ (2.83 )

OTHER COMPREHENSIVE INCOME [Abstract]
OTHER COMPREHENSIVE INCOME	NOTE 17 - OTHER COMPREHENSIVE INCOME Other comprehensive income generally represents all changes in shareholders’ equity during the period, except those resulting from investments by, or distributions to, shareholders. During 2012 and 2013, the Company acquired four entities that operate in Canada. These Canadian entities maintain financial data in Canadian dollars. Upon consolidation, the Company translates the financial data from these foreign subsidiaries into U.S. dollars and records cumulative translation adjustments in other comprehensive income. The Company recorded $(1.2) million, $(7.7) million and ($4.9) million in translation adjustments, net of tax, in other comprehensive income during the years ended December 31, 2017, 2016 and 2015, respectively. Comprehensive income for the year ended December 31, 2016 was reduced by an $8.6 million charge recorded during the fourth quarter of 2016 to correct errors which accumulated during 2013, 2014 and 2015 due to the Company improperly recognizing an $8.6 million deferred tax asset on unrealized foreign currency losses not expected to be realized within one year. We assessed the materiality of this misstatement and concluded the misstatement was not material to the results of operations or financial condition for the years ended December 31, 2016 and 2015.

SUMMARY OF SIGNIFICANT ACCOUNTING AND BUSINESS POLICIES [Abstract]
Basis of Presentation	Basis of Presentation The Company’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The accompanying consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and its variable interest entity (“VIE”). DXP is the primary beneficiary of a VIE in which DXP owns 47.5% of the equity. DXP consolidates the financial statements of the VIE with the financial statements of DXP. As of December 31, 2017, the total assets of the VIE were approximately $5.2 million including approximately $4.5 million of fixed assets. DXP is the primary customer of the VIE. Consolidation of the VIE increased cost of sales by approximately $0.6 million and $1.3 million for the twelve months ended December 31, 2017 and 2016, respectively. The Company recognized a related income tax benefit of $0.2 million and $0.3 million related to the VIE for the years ended December 31, 2017 and 2016, respectively. At December 31, 2017, the owners of the 52.5% of the equity not owned by DXP included employees of DXP. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation; none affected net income.
Foreign Currency	Foreign Currency The financial statements of the Company’s Canadian subsidiaries are measured using local currencies as their functional currencies. Assets and liabilities are translated into U.S. dollars at current exchange rates, while income and expenses are translated at average exchange rates. Translation gains and losses are reported in other comprehensive income (loss). Gains and losses on transactions denominated in foreign currency are reported in consolidated statements of income (loss).
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with requires management to make estimates and assumptions in determining the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In the opinion of management, all adjustments necessary in order to make the financial statements not misleading have been included. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company’s presentation of cash includes cash equivalents. Cash equivalents are defined as short-term investments with maturity dates of 90 days or less at time of purchase. The Company places its cash and cash equivalents with institutions with high credit quality. However, at certain times, such cash and cash equivalents may be in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits. The Company has not historically experienced any losses when in excess of these limits.
Receivables and Credit Risk	Receivables and Credit Risk Trade receivables consist primarily of uncollateralized customer obligations due under normal trade terms, which usually require payment within 30 days of the invoice date. However, these payment terms are extended in select cases and customers may not pay within stated trade terms. The Company has trade receivables from a diversified customer base located primarily in the Rocky Mountain, Northeastern, Midwestern, Southeastern and Southwestern regions of the United States, and Canada. The Company believes no significant concentration of credit risk exists. The Company evaluates the creditworthiness of its customers' financial positions and monitors accounts on a regular basis. Provisions to the allowance for doubtful accounts are made monthly and adjustments are made periodically (as circumstances warrant) based upon management’s best estimate of the collectability of such accounts. The Company writes off uncollectible trade accounts receivable when the accounts are determined to be uncollectible. No customer represents more than 10% of consolidated sales. Changes in this allowance for 2017, 2016 and 2015 were as follows ( in thousands Years Ended December 31, 2017 2016 2015 Balance at beginning of year $ 8,160 $ 9,364 $ 8,713 Charged to costs and expenses 3,367 180 2,014 Charged to other accounts 22 3 (17 ) 2 1,255 2 Deductions (2,534 ) 1 (1,367 ) 1 (2,618 ) 1 Balance at end of year $ 9,015 $ 8,160 $ 9,364 ( 1) Uncollectible accounts written off, net of recoveries (2) Includes allowance for doubtful accounts from acquisitions and divestiture (3) Primarily due to translation adjustments
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company is required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. US GAAP establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. US GAAP prioritizes the inputs into three levels that may be used to measure fair value: Level 1 Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2 Level 2 applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Level 3 Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. See Note 4 for further information regarding the Company’s financial instruments.
Inventories	Inventories Inventories consist principally of finished goods and are priced at net realizable value Provisions
Property and Equipment	Property and Equipment Property and equipment are carried on the basis of cost. Depreciation of property and equipment is computed using the straight-line method over their estimated useful lives. Maintenance and repairs of depreciable assets are charged against earnings as incurred. When properties are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and gains or losses are credited or charged to earnings. The principal estimated useful lives used in determining depreciation are as follows: Buildings 20-39 years Building improvements 10-20 years Furniture, fixtures and equipment 3-20 years Leasehold improvements Shorter of estimated useful life or related lease term
Impairment of Goodwill and Other Intangible Assets	Impairment of Goodwill and Other Intangible Assets The Company tests goodwill and other indefinite lived intangible assets for . The Company assigns the carrying value of these intangible assets to its "reporting units" and applies the test for goodwill at the reporting unit level. A reporting unit is defined as an operating segment or one level below a segment (a "component") if the component is a business and discrete information is prepared and reviewed regularly by segment management. The Company’s goodwill impairment assessment first permits evaluating qualitative factors to determine if a reporting unit's carrying value would more likely than not exceed its fair value. If the Company concludes, based on the qualitative assessment, that a reporting unit's carrying value would more likely than not exceed its fair value, the Company would perform a two-step quantitative test for that reporting unit. When a quantitative assessment is performed, the first step is to identify a potential impairment, and the second step measures the amount of the impairment loss, if any. Goodwill is deemed to be impaired if the carrying amount of a reporting unit’s goodwill exceeds its estimated fair value. During the third and fourth quarter of 2015, DXP performed interim impairment tests using a quantitative approach and recognized goodwill impairments of $57.8 million and $9.8 million, respectively. No impairment of goodwill was required in 2017 and 2016.
Impairment of Long-Lived Assets, Excluding Goodwill	Impairment of Long-Lived Assets, Excluding Goodwill The Company tests long-lived assets or asset groups for recoverability on an annual basis and when events or changes in circumstances indicate that their carrying amount may not be recoverable. Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed significantly before the end of its estimated useful life. Recoverability is assessed based on the carrying amount of the asset and its fair value which is generally determined based on the sum of the undiscounted cash flows expected to result from the use and the eventual disposal of the asset, as well as specific appraisal in certain instances. An impairment loss is recognized when the carrying amount is not recoverable and exceeds fair value. No impairment of long-lived assets excluding goodwill, was required in 2017, 2016 and 2015.
Share-based Compensation	Share-based Compensation The Company uses restricted stock for share-based compensation programs. The Company measures compensation cost with respect to equity instruments granted as stock-based payments to employees based upon the estimated fair value of the equity instruments at the date of the grant. The cost as measured is recognized as expense over the period which an employee is required to provide services in exchange for the award.
Revenue Recognition	Revenue Recognition For binding agreements to fabricate tangible assets to customer specifications, the Company recognizes revenues using the percentage of completion method. Under this method, revenues are recognized as costs are incurred and include estimated profits calculated on the basis of the relationship between costs incurred and total estimated costs at completion. If at any time expected costs exceed the value of the contract, the loss is recognized immediately. Revenues of approximately $40.6 million, $31.5 million, and $47.5 million were recognized on contracts in process for the years ended December 31, 2017, 2016, and 2015, respectively. The typical time span of these contracts is approximately one to two years. For other sales, the Company recognizes revenues when an agreement is in place, the price is fixed, title for product passes to the customer or services have been provided and collectability is reasonably assured, which is generally upon delivery to the customer. Revenues are recorded net of sales taxes. The Company reserves for potential customer returns based upon the historical level of returns.
Shipping and Handling Costs	Shipping and Handling Costs The Company classifies shipping and handling charges billed to customers as sales. Shipping and handling charges paid to others are classified as a component of cost of sales.
Self-insured Insurance and Medical Claims	Self-insured Insurance and Medical Claims We generally retain up to $100,000 of risk for each claim for workers compensation, general liability, automobile and property loss. We accrue for the estimated loss on the self-insured portion of these claims. The accrual is adjusted quarterly based upon reported claims information. The actual cost could deviate from the recorded estimate. We generally retain up to $175,000 of risk on each medical claim for our employees and their dependents with the exception of less than 0.05% of employees where a higher risk is retained. We accrue for the estimated outstanding balance of unpaid medical claims for our employees and their dependents. The accrual is adjusted monthly based on recent claims experience. The actual claims could deviate from recent claims experience and be materially different from the reserve. The accrual for these claims at December 31, 2017 and 2016 was approximately $2.7 million and $3.1 million, respectively.
Purchase Accounting	Purchase Accounting DXP estimates the fair value of assets, including property, machinery and equipment and their related useful lives and salvage values, intangibles and liabilities when allocating the purchase price of an acquisition. The fair value estimates are developed using the best information available.
Cost of Sales and Selling, General and Administrative Expense	Cost of Sales and Selling, General and Administrative Expense Cost of sales includes product and product related costs, inbound freight charges, internal transfer costs and depreciation. Selling, general and administrative expense includes purchasing and receiving costs, inspection costs, warehousing costs, depreciation and amortization.
Debt Issuance Cost Amortization	Debt Issuance Cost Amortization Fees paid to DXP’s lenders to secure a firm commitment on a term loan and revolving line of credit are presented as a direct deduction from the carrying amount of the debt liability. For the term loan, fees paid by DXP are amortized over the life of the loan as additional interest. Fees paid to secure a firm commitment from our lender on a revolving line of credit are amortized on a straight-line basis over the entire term of the arrangement. The total unamortized debt issuance costs reported on the consolidated balance sheets as of December 31, 2017 and 2016 was $10.1 million and $1.0 million, respectively. In connection with the extinguishment of the previously existing credit facility we recorded a $0.6 million write-off of debt issuance costs, which was included in interest expense during the third quarter of 2017.
Income Taxes	Income Taxes The Company utilizes the asset and liability method of accounting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and income tax bases of assets and liabilities. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to reverse. Valuation allowances are established to reduce deferred income tax assets to the amounts expected to be realized under a more likely than not criterion.
Accounting for Uncertainty in Income Taxes	Accounting for Uncertainty in Income Taxes A position taken or expected to be taken in a tax return is recognized in the financial statements when it is more likely than not (i.e. a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states. With few exceptions, the Company is no longer subject to U. S. federal, state and local tax examination by tax authorities for years prior to 2012. The Company's policy is to recognize interest related to unrecognized tax benefits as interest expense and penalties as operating expenses. The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) includes net income, foreign currency translation adjustments and unrealized gains and losses on certain investments in debt and equity securities. The Company’s other comprehensive (loss) income is comprised of changes in the market value of an investment with quoted market prices in an active market for identical instruments and translation adjustments from translating foreign subsidiaries to the reporting currency. Comprehensive income for the year ended December 31, 2016 was reduced by an $8.6 million charge recorded during the fourth quarter of 2016 to correct errors which accumulated during 2013, 2014 and 2015 due to the Company improperly recognizing an $8.6 million deferred tax asset on unrealized foreign currency losses not expected to be realized within one year. We assessed the materiality of this misstatement and concluded the misstatement was not material to the results of operations or financial condition for the years ended December 31, 2016 and 2015.
Out-of-Period Items	Out-of-Period Items Deferred tax liabilities related to intangibles for customer relationships acquired in Canada during 2012 and 2013 were reduced by $2.2 million during the fourth quarter of 2017 to correct the tax rate used to establish the deferred tax liabilities at the dates of acquisition. The Company evaluated the misstatement of each period since these acquisitions were completed and concluded the effects were immaterial. During the first quarter of 2015, we identified a $2.5 million ($1.6 million net of tax) overstatement of an accrual at December 31, 2014, which overstated 2014 selling, general and administrative expense. We recorded an out-of-period adjustment to correct this overstatement in the quarter ended March 31, 2015. During the fourth quarter of 2015, we realized $1.5 million of net tax benefits related to events which occurred in earlier years. These out-of-period items reduced the 2015 net loss by $3.1 million and 2015 basic and diluted net loss per share by $0.21. We assessed the materiality of this overstatement and concluded the overstatement was not material to the results of operations or financial condition for the year ended December 31, 2015.
