Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Significant Accounting Policies	Organization and Significant Accounting Policies Organization and Nature of Operations Flotek Industries, Inc. (“Flotek” or the “Company”) is a global, diversified, technology-driven company that develops and supplies chemistries and services to the oil and gas industries, and high value compounds to companies that make food and beverages, cleaning products, cosmetics, and other products that are sold in consumer and industrial markets. The Company’s oilfield business includes specialty chemistries and logistics which enable its customers to pursue improved efficiencies and performance in the drilling and completion of their wells. The Company also provides automated bulk material handling, loading facilities, and blending capabilities. The Company processes citrus oil to produce (1) high value compounds used as additives by companies in the flavors and fragrances markets and (2) environmentally friendly chemistries for use in numerous industries around the world, including the oil and gas (“O&G”) industry. Flotek operates in over 20 domestic and international markets. Customers include major integrated O&G companies, oilfield services companies, independent O&G companies, pressure-pumping service companies, national and state-owned oil companies, and international supply chain management companies. The Company also serves customers who purchase non-energy-related citrus oil and related products, including household and commercial cleaning product companies, fragrance and cosmetic companies, and food manufacturing companies. Flotek was initially incorporated under the laws of the Province of British Columbia on May 17, 1985. On October 23, 2001, Flotek changed its corporate domicile to the state of Delaware. Basis of Presentation The accompanying Unaudited Condensed Consolidated Financial Statements and accompanying footnotes (collectively the “Financial Statements”) reflect all adjustments, in the opinion of management, necessary for fair presentation of the financial condition and results of operations for the periods presented. All such adjustments are normal and recurring in nature. The Financial Statements, including selected notes, have been prepared in accordance with applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting and do not include all information and disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for comprehensive financial statement reporting. These interim Financial Statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (“Annual Report”). A copy of the Annual Report is available on the SEC’s website, www.sec.gov , under the Company’s ticker symbol (“FTK”) or on Flotek’s website, www.flotekind.com . The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018 . During the fourth quarter of 2016, the Company classified the Drilling Technologies and Production Technologies segments as held for sale based on management’s intention to sell these businesses. The Company’s historical financial statements have been revised to present the operating results of the Drilling Technologies and Production Technologies segments as discontinued operations. The results of operations of Drilling Technologies and Production Technologies are presented as “Loss from discontinued operations” in the statement of operations and the related cash flows of these segments have been reclassified to discontinued operations for all periods presented. The assets and liabilities of the Drilling Technologies and Production Technologies segments were reclassified to “Assets held for sale” and “Liabilities held for sale,” respectively, in the consolidated balance sheets through September 2017. During 2017, the Company completed the sale or disposal of the assets and transfer or liquidation of liabilities and obligations of each of the Drilling Technologies and Production Technologies segments. Revenue Recognition The Company recognizes revenues to depict the transfer of control of promised goods or services to its customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. Refer to Note 5 — “Revenue from Contracts with Customers” for further discussion on Revenue. The Company recognizes revenue based on the Accounting Standards Codification (“ASC”) 606 five-step model when all of the following criteria have been met: (i) a contract with a customer exists, (ii) performance obligations have been identified, (iii) the price to the customer has been determined, (iv) the price to the customer has been allocated to the performance obligations, and (v) performance obligations are satisfied. Products and services are sold with fixed or determinable prices. Certain sales include right of return provisions, which are considered when recognizing revenue and deferred accordingly. Deposits and other funds received in advance of delivery are deferred until the transfer of control is complete. For certain contracts, the Company recognizes revenue under the percentage-of-completion method of accounting, measured by the percentage of “costs incurred to date” to the “total estimated costs of completion.” This percentage is applied to the “total estimated revenue at completion” to calculate proportionate revenue earned to date. For the three and nine months ended September 30, 2018 and 2017 , the percentage-of-completion revenue accounted for less than 0.1% of total revenue during the respective time periods. This resulted in immaterial unfulfilled performance obligations and immaterial contract assets and/or liabilities for which the Company did not record adjustments to opening retained earnings as of December 31, 2015 or for any periods previously presented. As an accounting policy election, the Company excludes from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenues. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results could differ from these estimates. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassifications did not impact net loss .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Application of New Accounting Standards Effective January 1, 2018, the Company adopted the accounting guidance in Accounting Standards Update (“ASU”) No. 2014-09, “ Revenue from Contracts with Customers .” This standard supersedes most of the existing revenue recognition requirements in U.S. GAAP under Accounting Standards Codification (“ASC”) 605 and establishes a new revenue standard, ASC 606. This new standard requires entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted ASC 606 using the full retrospective method. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. Refer to Note 5 — “Revenue from Contracts with Customers” for further information surrounding adoption of this new standard. Effective January 1, 2018, the Company adopted the accounting guidance in ASU No. 2016-15, “ Classification of Certain Cash Receipts and Cash Payments. ” This standard addressed eight specific cash flow issues with the objective of reducing the existing diversity in practice. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. The Company applied this standard prospectively, where applicable, as there were no historical transactions affected by this implementation. Effective January 1, 2018, the Company adopted the accounting guidance in ASU No. 2017-01, “ Clarifying the Definition of a Business. ” This standard provided additional guidance on whether an integrated set of assets and activities constitutes a business. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. The Company applied this standard prospectively and, therefore, prior periods were not adjusted. In addition, the Company had no activity during the nine months ended September 30, 2018 that was required to be treated differently under this ASU than previously issued guidance. Effective January 1, 2018, the Company adopted the accounting guidance in ASU No. 2017-09, “ Scope of Modification Accounting .” This standard provided guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. The Company applied this standard prospectively and, therefore, prior periods presented were not adjusted. There were no changes to the terms or conditions of current share-based payment awards during the nine months ended September 30, 2018 . New Accounting Requirements and Disclosures In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, “ Leases .” This standard requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. The pronouncement is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period and should be applied using a modified retrospective transition approach, with early application permitted. In July 2018, the FASB issued ASU No. 2018-10 and ASU No. 2018-11, which provide codification and targeted improvements to the original guidance issued, as well as modifies the transition methods available upon adoption. The Company intends to adopt the new standard in the first quarter of 2019 and intends to elect the available practical expedients upon adoption. The Company is currently evaluating all potential leases, assessing system readiness, including software procured from third-party providers, and completing an analysis of information necessary to restate prior period consolidated financial statements, if applicable. The Company anticipates this standard will have a significant impact on the consolidated balance sheets. However, the adoption is not expected to have a significant impact on the consolidated statements of operations. The Company is continuing to evaluate the impact the pronouncement will have on the related disclosures. In June 2016, the FASB issued ASU No. 2016-13, “ Measurement of Credit Losses on Financial Instruments .” This standard replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In February 2018, the FASB issued ASU No. 2018-02, “ Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income .” This standard allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. The pronouncement is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted in any interim period. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In June 2018, the FASB issued ASU No. 2018-07, “ Improvements to Nonemployee Share-Based Payment Accounting .” This standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The pronouncement is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted no earlier than an entity’s adoption date of Topic 606. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-13, “ Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement .” This standard removes, modifies, and adds additional requirements for disclosures related to fair value measurement in ASC 820. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted in any interim period. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations During the fourth quarter of 2016, the Company initiated a strategic restructuring of its business to enable a greater focus on its core businesses in energy chemistry and consumer and industrial chemistry. The Company executed a plan to sell or otherwise dispose of the Drilling Technologies and Production Technologies segments. An investment banking advisory services firm was engaged and actively marketed these segments. Disposal of the Drilling Technologies and Production Technologies reporting segments represented a strategic shift that would have a major effect on the Company’s operations and financial results. The Company met all of the criteria to classify the Drilling Technologies and Production Technologies segments’ assets and liabilities as held for sale in the fourth quarter of 2016. Effective December 31, 2016, the Company classified the assets, liabilities, and results of operations for these two segments as “Discontinued Operations” for all periods presented. On May 22, 2017 , the Company completed the sale of substantially all of the assets and transfer of certain specified liabilities and obligations of the Company’s Drilling Technologies segment to National Oilwell Varco, L.P. (“NOV”) for $17.0 million in cash consideration, subject to normal working capital adjustments, with $1.5 million held back by NOV for up to 18 months to satisfy potential indemnification claims. On May 23, 2017 , the Company completed the sale of substantially all of the assets and transfer of certain specified liabilities and obligations of the Company’s Production Technologies segment to Raptor Lift Solutions, LLC (“Raptor Lift”) for $2.9 million in cash consideration, with $0.4 million held back by Raptor Lift to satisfy potential indemnification claims. On August 16, 2017 , the Company completed the sale of substantially all of the remaining assets of the Company’s Drilling Technologies segment to Galleon Mining Tools, Inc. for $1.0 million in cash consideration and a note receivable of $1.0 million due in one year . The sale or disposal of the assets and transfer or liquidation of liabilities and obligations of these segments was completed in 2017. The Company has no continuing involvement with the discontinued operations. The following summarized financial information has been segregated from continuing operations and reported as Discontinued Operations for the three and nine months ended September 30, 2017 (in thousands): Three months ended September 30, 2017 Nine months ended September 30, 2017 Drilling Technologies Revenue $ — $ 11,534 Cost of revenue — (7,259 ) Selling, general and administrative (791 ) (6,562 ) Research and development — (6 ) Gain on disposal of long-lived assets 36 97 Loss from operations (755 ) (2,196 ) Other income (expense) 26 (91 ) Gain (loss) on sales of businesses 463 (902 ) Loss on write-down of assets held for sale — (6,831 ) Loss before income taxes (266 ) (10,020 ) Income tax benefit 581 3,473 Net income (loss) from discontinued operations $ 315 $ (6,547 ) Production Technologies Revenue $ — $ 4,002 Cost of revenue — (3,189 ) Selling, general and administrative (64 ) (1,739 ) Research and development — (364 ) Loss from operations (64 ) (1,290 ) Other expense — (52 ) Gain on sale of businesses 61 233 Loss on write-down of assets held for sale — (9,718 ) Loss before income taxes (3 ) (10,827 ) Income tax benefit 7 3,753 Net income (loss) from discontinued operations $ 4 $ (7,074 ) Drilling Technologies and Production Technologies Income (loss) from discontinued operations, net of tax $ 319 $ (13,621 ) At December 31, 2017 , all remaining assets and liabilities of the discontinued operations were assumed by the Company’s continuing operations. These balances included $0.3 million of net accounts receivable, $1.4 million of sales price hold-back that will be received during 2018, and $1.4 million of accrued liabilities to be settled in 2018. Assets Held for Sale During the second quarter of 2018, the Company committed to a plan to divest the revenue generating assets associated with the Dalton, Georgia facility within the Energy Chemistry Technologies segment. The Company determined that the divestiture of this business line did not meet the criteria for discontinued operations presentation, as the commitment to divest this business line does not represent a strategic shift that will have a major effect on its operations and financial results. These assets were available for immediate sale in their present condition, subject to only usual and customary terms. During the three months ended June 30, 2018, a loss on write-down of assets held for sale of $2.6 million was recorded to state the assets at fair value less costs to sell. The assets classified as held for sale at December 31, 2017 is as follows (in thousands): Property and equipment, net $ 4,998 Valuation allowance — Assets held for sale, net $ 4,998 On September 10, 2018 , the Company completed the sale of the assets of the Dalton, Georgia facility to T&L Properties of Dalton, LLC for $1.8 million in cash consideration. The Company recorded a loss on the sale of the business of $0.4 million for the three months ended September 30, 2018 .

Revenue from Contracts with Cus

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Effective January 1, 2018, the Company adopted ASC 606 using the full retrospective method applied to those contracts which were not completed as of December 31, 2015. As a result of electing the full retrospective adoption approach, results for reporting periods beginning after December 31, 2015 are presented under ASC 606. There was no material impact upon the adoption of ASC 606. As revenue is primarily related to product sales accounted for at a point in time and service contracts that are primarily short-term in nature (typically less than 30 days), the Company did not record any adjustments to opening retained earnings at December 31, 2015 or for any periods previously presented. Revenues are recognized when control of the promised goods or services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. In recognizing revenue for products and services, the Company determines the transaction price of purchase orders or contracts with customers, which may consist of fixed and variable consideration. Determining the transaction price may require significant judgment by management, which includes identifying performance obligations, estimating variable consideration to include in the transaction price, and determining whether promised goods or services can be distinguished in the context of the contract. Variable consideration typically consists of product returns and is estimated based on the amount of consideration the Company expects to receive. Revenue accruals are recorded on an ongoing basis to reflect updated variable consideration information. For certain contracts, the Company recognizes revenue under the percentage-of-completion method of accounting, measured by the percentage of “costs incurred to date” to the “total estimated costs of completion.” This percentage is applied to the “total estimated revenue at completion” to calculate proportionate revenue earned to date. For the three and nine months ended September 30, 2018 and 2017 , the percentage-of-completion revenue accounted for less than 0.1% of total revenue during the respective time periods. This resulted in immaterial unfulfilled performance obligations and immaterial contract assets and/or liabilities, for which the Company did not record adjustments to opening retained earnings as of December 31, 2015 or for any periods previously presented. The vast majority of the Company’s products are sold at a point in time and service contracts are short-term in nature. Sales are billed on a monthly basis with payment terms customarily 30 days from invoice receipt. In addition, sales taxes are excluded from revenues. Disaggregation of Revenue The Company has disaggregated revenues by product sales (point-in-time revenue recognition) and service revenue (over-time revenue recognition), where product sales accounted for over 95% of total revenue for the three and nine months ended September 30, 2018 and 2017 . The Company differentiates revenue and cost of revenue (excluding depreciation and amortization) based on whether the source of revenue is attributable to products or services. Revenue and cost of revenue (excluding depreciation and amortization) disaggregated by revenue source are as follows (in thousands): Three months ended September 30, Nine months ended September 30, 2018 2017 2018 2017 Revenue: Products $ 69,671 $ 77,956 $ 186,552 $ 240,306 Services 1,318 1,502 4,039 4,283 $ 70,989 $ 79,458 $ 190,591 $ 244,589 Cost of revenue (excluding depreciation and amortization): Products $ 52,647 $ 55,846 $ 142,670 $ 163,587 Services 1,436 1,345 3,852 3,802 $ 54,083 $ 57,191 $ 146,522 $ 167,389 Arrangements with Multiple Performance Obligations The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the total transaction price is allocated to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. Standalone selling prices are generally determined based on the prices charged to customers (“observable standalone price”) or an expected cost plus a margin approach. For combined products and services within a contract, the Company accounts for individual products and services separately if they are distinct (i.e. if a product or service is separately identifiable from other items in the contract and if a customer can benefit from it on its own or with other resources that are readily available to the customer). The consideration is allocated between separate products and services within a contract based on the prices at the observable standalone price. For items that are not sold separately, the expected cost plus a margin approach is used to estimate the standalone selling price of each performance obligation. Contract Balances Under revenue contracts for both products and services, customers are invoiced once the performance obligations have been satisfied, at which point payment is unconditional. Accordingly, no revenue contracts give rise to contract assets or liabilities under ASC 606. Practical Expedients and Exemptions The Company has elected to apply several practical expedients as discussed below: • Sales commissions are expensed when incurred because the amortization period would have been one year or less. These costs are recorded within segment selling and administrative expenses. • The majority of the Company’s services are short-term in nature with a contract term of one year or less. For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14, exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. • The Company’s payment terms are short-term in nature with settlements of one year or less. The Company has utilized the practical expedient in ASC 606-10-32-18, exempting the Company from adjusting the promised amount of consideration for the effects of a significant financing component given that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. • In most service contracts, the Company has the right to consideration from a customer in an amount that corresponds directly with the value to the customer of the Company’s performance completed to date. For these contracts, the Company has utilized the practical expedient in ASC 606-10-55-18, allowing the Company to recognize revenue in the amount to which it has a right to invoice. Accordingly, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed.

During the second quarter of 2018 , the Company recognized a goodwill impairment charge of $37.2 million in the Energy Chemistry Technologies (“ECT”) reporting unit, which resulted from sustained under-performance and lower expectations related to the reporting unit. As a result of these factors, a qualitative analysis, and additional risks associated with the business, the Company concluded that sufficient indicators existed to require an interim quantitative assessment of goodwill for that reporting unit as of June 30, 2018 . The fair value of the reporting unit was estimated based on an analysis of the present value of future discounted cash flows. The significant estimates used in the discounted cash flows model included the Company’s weighted average cost of capital, projected cash flows and the long-term rate of growth. The assumptions were based on the actual historical performance of the reporting unit and took into account a recent weakening of operating results in an improving market environment. The excess of the reporting unit’s carrying value over the estimated fair value was recorded as the goodwill impairment charge during the three months ended June 30, 2018 and represented all of the ECT reporting unit’s goodwill. No impairments of goodwill were recognized in the Consumer and Industrial Chemistry Technologies reporting unit during the three and nine months ended September 30, 2018 . During the three and nine months ended September 30, 2017 , no impairments of goodwill were recognized.

Debt Disclosure [Abstract]
Long-Term Debt and Credit Facility	Long-Term Debt and Credit Facility Long-term debt is as follows (in thousands): September 30, 2018 December 31, 2017 Long-term debt, classified as current: Borrowings under revolving credit facility $ 53,402 $ 27,950 Borrowing under the revolving credit agreement is classified as current debt as a result of the required lockbox arrangement and the subjective acceleration clause. Credit Facility On May 10, 2013 , the Company and certain of its subsidiaries (the “Borrowers”) entered into an Amended and Restated Revolving Credit, Term Loan and Security Agreement (as amended, the “Credit Facility”) with PNC Bank, National Association (“PNC Bank”). The Company may borrow under the Credit Facility for working capital, permitted acquisitions, capital expenditures and other corporate purposes. The Credit Facility continues in effect until May 10, 2022 . Under terms of the Credit Facility, the Company has total borrowing availability of $75 million under a revolving credit facility. A term loan was repaid in May 2017 and may not be re-borrowed. The Credit Facility is secured by substantially all of the Company’s domestic real and personal property, including accounts receivable, inventory, land, buildings, equipment and other intangible assets. The Credit Facility contains customary representations, warranties, and both affirmative and negative covenants. The Company was in compliance with all debt covenants at September 30, 2018 . In the event of default, PNC Bank may accelerate the maturity date of any outstanding amounts borrowed under the Credit Facility. Effective June 13, 2018 , the Company entered into an Eleventh Amendment to the Credit Facility which, among other things, maintains the maximum revolving advance amount at $75 million , but adds a collateral block equal to $10 million minus the amount of any collateral value in excess of $75 million and, to the extent not duplicated, any inventory collateral in excess of $52 million . Compliance with the fixed charge coverage ratio and the leverage ratio is suspended through December 31, 2018, as long as there is not a financial covenant trigger event, which occurs if undrawn availability is less than $15 million at any month-end through December 31, 2018. At September 30, 2018 , undrawn availability for this calculation was $21.0 million . The Credit Facility contains financial covenants to maintain a fixed charge coverage ratio and a leverage ratio, as well as establishes an annual limit on capital expenditures. The fixed charge coverage ratio is the ratio of (a) earnings before interest, taxes, depreciation, and amortization (“EBITDA”), adjusted for non-cash stock-based compensation, during the period to (b) all debt payments during the period. The fixed charge coverage ratio requirement begins for the quarter ended March 31, 2019 at 1.10 to 1.00 , and for each annualized fiscal quarter in 2019 and thereafter. The leverage ratio (funded debt to adjusted EBITDA) requirement begins for the quarter ended March 31, 2019, at not greater than 3.00 to 1.00 , and for each annualized fiscal quarter in 2019 and thereafter. These financial covenants will be tested earlier if a financial covenant trigger event occurs. Following a triggering event, the fixed charge coverage ratio must be maintained at no less than 1.10 to 1.00 and the leverage ratio must be maintained at no greater than 3.00 to 1.00 as of the last day of the quarter. The annual limit on capital expenditures for 2018 and each fiscal year thereafter is $26 million . The annual limit on capital expenditures is reduced if the undrawn availability under the revolving credit facility falls below $15 million at any month-end. The Credit Facility restricts the payment of cash dividends on common stock and limits the amount that may be used to repurchase common stock and preferred stock. Beginning with fiscal year 2017, the Credit Facility includes a provision that 25% of EBITDA minus cash paid for taxes, dividends, debt payments, and unfunded capital expenditures, not to exceed $3.0 million for any fiscal year, be paid on the outstanding balance within 75 days of the fiscal year end. For the year ended December 31, 2017 , there was no additional payment required based on this provision. Each of the Company’s domestic subsidiaries is fully obligated for Credit Facility indebtedness as a borrower or as a guarantor. (a) Revolving Credit Facility Under the revolving credit facility, the Company may borrow up to $75 million through May 10, 2022 . This includes a sublimit of $10 million that may be used for letters of credit. The revolving credit facility is secured by substantially all of the Company’s domestic accounts receivable and inventory. At September 30, 2018 , eligible accounts receivable and inventory securing the revolving credit facility provided total borrowing capacity of $69.0 million under the revolving credit facility. Available borrowing capacity, net of outstanding borrowings, was $15.2 million at September 30, 2018 . The interest rate on advances under the revolving credit facility varies based on the fixed charge coverage ratio. Rates range (a) between PNC Bank’s base lending rate plus 1.5% to 2.0% or (b) between the London Interbank Offered Rate (LIBOR) plus 2.5% to 3.0% . PNC Bank’s base lending rate was 5.25% at September 30, 2018 . The Company is required to pay a monthly facility fee of 0.25% per annum, on any unused amount under the commitment based on daily averages. At September 30, 2018 , $53.4 million was outstanding under the revolving credit facility, with $1.4 million borrowed as base rate loans at an interest rate of 7.25% and $52.0 million borrowed as LIBOR loans at an interest rate of 5.23% . (b) Term Loan The amount borrowed under the term loan was reset to $10 million effective as of September 30, 2016 . Monthly principal payments of $0.2 million were required. On May 22, 2017 , the Company repaid the outstanding balance of the term loan. No additional amount may be re-borrowed under the term loan.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding combined with dilutive common share equivalents outstanding, if the effect is dilutive. Potentially dilutive securities were excluded from the calculation of diluted loss per share for the three and nine months ended September 30, 2018 and 2017 , since including them would have an anti-dilutive effect on loss per share due to the net loss incurred during the periods. Securities convertible into shares of common stock that were not considered in the diluted loss per share calculations were 0.9 million restricted stock units for the three and nine months ended September 30, 2018 , and 12,100 stock options and 1.2 million restricted stock units for the three and nine months ended September 30, 2017 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes financial assets and liabilities into the three levels of the fair value hierarchy. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value and bases categorization within the hierarchy on the lowest level of input that is available and significant to the fair value measurement. • Level 1 — Quoted prices in active markets for identical assets or liabilities; • Level 2 — Observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Significant unobservable inputs that are supported by little or no market activity or that are based on the reporting entity’s assumptions about the inputs. Fair Value of Other Financial Instruments The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses, approximate fair value due to the short-term nature of these accounts. The Company had no cash equivalents at September 30, 2018 or December 31, 2017 . The carrying amount and estimated fair value of the Company’s long-term debt are as follows (in thousands): September 30, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Borrowings under revolving credit facility 53,402 53,402 27,950 27,950 The carrying amount of borrowings under the revolving credit facility approximates its fair value because the interest rates are variable. Assets Measured at Fair Value on a Nonrecurring Basis The Company’s non-financial assets, including property and equipment, goodwill, and other intangible assets are measured at fair value on a non-recurring basis and are subject to fair value adjustment in certain circumstances. During the three months ended June 30, 2018 , the Company recorded an impairment of $37.2 million for goodwill in the Energy Chemistry Technologies reporting unit (see Note 9 ). No impairments of goodwill were recognized during the three and nine months ended September 30, 2017 . No impairments of property and equipment or other intangible assets were recognized during the three and nine months ended September 30, 2018 and 2017 .

Income Taxes	Income Taxes A reconciliation of the U.S. federal statutory tax rate to the Company’s effective income tax rate is as follows: Three months ended September 30, Nine months ended September 30, 2018 2017 2018 2017 U.S. federal statutory tax rate (21.0 )% (35.0 )% (21.0 )% (35.0 )% State income taxes, net of federal benefit (2.3 ) 14.3 0.3 6.7 Non-U.S. income taxed at different rates (4.6 ) 8.9 (0.7 ) 5.4 Reduction in tax benefit related to stock-based awards 0.8 15.8 1.4 14.1 Non-deductible expenses 6.3 8.5 10.1 4.5 Research and development credit 4.7 (13.5 ) (0.4 ) (7.1 ) Valuation allowance 3.7 — 34.2 — Other 4.7 1.5 0.5 (1.0 ) Effective income tax rate (7.7 )% 0.5 % 24.4 % (12.4 )% Fluctuations in effective tax rates have historically been impacted by permanent tax differences with no associated income tax impact, changes in state apportionment factors, including the effect on state deferred tax assets and liabilities, and non-U.S. income taxed at different rates. Net deferred tax assets arise due to the recognition of income and expense items for tax purposes, which differ from those used for financial statement purposes. ASC 740, Income Taxes, provides for the recognition of deferred tax assets if realization of such assets is more likely than not. In assessing the need for a valuation allowance in the second quarter of 2018, the Company considered all available objective and verifiable evidence, both positive and negative, including historical levels of pre-tax income (loss) both on a consolidated basis and tax reporting entity basis, legislative developments, and expectations and risks associated with estimates of future pre-tax income. As a result of this analysis, the Company determined that it is more likely than not that it will not realize the benefits of certain deferred tax assets and, therefore, has recorded a valuation allowance against the carrying value of net deferred tax assets, except for deferred tax liabilities related to non-amortizable intangible assets and certain state jurisdictions. Comprehensive tax reform legislation enacted in December 2017, commonly referred to as the Tax Cuts and Jobs Acts (“2017 Tax Act”), made significant changes to U.S. federal income tax laws. The 2017 Tax Act, among other things, reduced the corporate income tax rate from 35% to 21% , partially limited the deductibility of business interest expense and net operating losses, provided additional limitations on the deductibility of executive compensation, imposed a one-time tax on unrepatriated earnings from certain foreign subsidiaries, taxed offshore earnings at reduced rates regardless of whether they are repatriated, and allowed the immediate deduction of certain new investments instead of deductions for depreciation expense over time. The Company has not completed its determination of the impacts of the 2017 Tax Act and recorded provisional amounts in its financial statements as of December 31, 2017. The Company has continued to evaluate the 2017 Tax Act and will adjust the provisional amounts as additional information is obtained. The ultimate impact of the 2017 Tax Act may differ from the provisional amounts recorded due to additional information becoming available, changes in interpretation of the 2017 Tax Act, and additional regulatory guidance that may be issued. No adjustments to the provisional amounts were recorded during the three and nine months ended September 30, 2018 . In January 2017, the Internal Revenue Service notified the Company that it will examine the Company’s federal tax returns for the year ended December 31, 2014. No adjustments have been asserted, and management believes that sustained adjustments, if any, would not have a material effect on the Company’s financial position, results of operations, or liquidity.

Segment Reporting [Abstract]
Business Segment, Geographic and Major Customer Information	Business Segment, Geographic and Major Customer Information Segment Information Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by chief operating decision-makers in deciding how to allocate resources and assess performance. The operations of the Company are categorized into two reportable segments: Energy Chemistry Technologies and Consumer and Industrial Chemistry Technologies. • Energy Chemistry Technologies designs, develops, manufactures, packages, and markets specialty chemistries used in oil and natural gas well drilling, cementing, completion, and stimulation. In addition, the Company’s chemistries are used in specialized enhanced and improved oil recovery markets. Activities in this segment also include construction and management of automated material handling facilities and management of loading facilities and blending operations for oilfield services companies. • Consumer and Industrial Chemistry Technologies designs, develops, and manufactures products that are sold to companies in the flavor and fragrance industry and the specialty chemical industry. These technologies are used by beverage and food companies, fragrance companies, and companies providing household and industrial cleaning products. The Company evaluates performance based upon a variety of criteria. The primary financial measure is segment operating income. Various functions, including certain sales and marketing activities and general and administrative activities, are provided centrally by the corporate office. Costs associated with corporate office functions, other corporate income and expense items, and income taxes are not allocated to reportable segments. Summarized financial information of the reportable segments is as follows (in thousands): For the three months ended September 30, Energy Chemistry Technologies Consumer and Industrial Chemistry Technologies Corporate and Other Total 2018 Net revenue from external customers $ 53,709 $ 17,280 $ — $ 70,989 Income (loss) from operations 3,920 858 (8,000 ) (3,222 ) Depreciation and amortization 1,734 699 524 2,957 Capital expenditures 302 171 861 1,334 2017 Net revenue from external customers $ 61,167 $ 18,291 $ — $ 79,458 Income (loss) from operations 6,867 985 (10,955 ) (3,103 ) Depreciation and amortization 1,863 590 614 3,067 Capital expenditures 324 682 641 1,647 For the nine months ended September 30, Energy Chemistry Technologies Consumer and Industrial Chemistry Technologies Corporate and Other Total 2018 Net revenue from external customers $ 134,324 $ 56,267 $ — $ 190,591 Income (loss) from operations (34,175 ) 3,937 (26,270 ) (56,508 ) Depreciation and amortization 5,300 2,049 1,635 8,984 Capital expenditures 2,480 767 1,314 4,561 2017 Net revenue from external customers $ 187,807 $ 56,782 $ — $ 244,589 Income (loss) from operations 24,715 5,906 (35,598 ) (4,977 ) Depreciation and amortization 5,507 1,752 1,832 9,091 Capital expenditures 2,794 1,580 1,781 6,155 Assets of the Company by reportable segments are as follows (in thousands): September 30, 2018 December 31, 2017 Energy Chemistry Technologies $ 145,853 $ 172,799 Consumer and Industrial Chemistry Technologies 132,381 116,600 Corporate and Other 15,068 35,491 Total segments 293,302 324,890 Held for sale — 4,998 Total assets $ 293,302 $ 329,888 Geographic Information Revenue by country is based on the location where services are provided and products are used.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Class Action Litigation On March 30, 2017, the U.S. District Court for the Southern District of Texas granted the Company’s motion to dismiss the four consolidated putative securities class action lawsuits that were filed in November 2015, against the Company and certain of its officers. The lawsuits were previously consolidated into a single case, and a consolidated amended complaint had been filed. The consolidated amended complaint asserted that the Company made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. The complaint sought an award of damages in an unspecified amount on behalf of a putative class consisting of persons who purchased the Company’s common stock between October 23, 2014 and November 9, 2015, inclusive. The lead plaintiff has appealed the District Court’s decision granting the motion to dismiss. In January 2016, three derivative lawsuits were filed, two in the District Court of Harris County, Texas (which have since been consolidated into one case) and one in the United States District Court for the Southern District of Texas, on behalf of the Company against certain of its officers and its current directors. The lawsuits allege violations of law, breaches of fiduciary duty, and unjust enrichment against the defendants. The Company believes the lawsuits are without merit and intends to vigorously defend against all claims asserted. Discovery has not yet commenced. At this time, the Company is unable to reasonably estimate the outcome of this litigation. In addition, as previously disclosed, the U.S. Securities and Exchange Commission had opened an inquiry related to similar issues to those raised in the above-described litigation. On August 21, 2017, the Company received a letter from the staff of the SEC stating that the inquiry has been concluded and that the staff does not intend to recommend an enforcement action against the Company. Other Litigation The Company is subject to routine litigation and other claims that arise in the normal course of business. Management is not aware of any pending or threatened lawsuits or proceedings that are expected to have a material effect on the Company’s financial position, results of operations or liquidity. Concentrations and Credit Risk The majority of the Company’s revenue is derived from the oil and gas industry. Customers include major oilfield services companies, major integrated oil and natural gas companies, independent oil and natural gas companies, pressure pumping service companies, and state-owned national oil companies. This concentration of customers in one industry increases credit and business risks. The Company is subject to concentrations of credit risk within trade accounts receivable, as the Company does not generally require collateral as support for trade receivables. In addition, the majority of the Company’s cash is maintained at a major financial institution and balances often exceed insurable amounts.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Unaudited Condensed Consolidated Financial Statements and accompanying footnotes (collectively the “Financial Statements”) reflect all adjustments, in the opinion of management, necessary for fair presentation of the financial condition and results of operations for the periods presented. All such adjustments are normal and recurring in nature. The Financial Statements, including selected notes, have been prepared in accordance with applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting and do not include all information and disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for comprehensive financial statement reporting. These interim Financial Statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (“Annual Report”). A copy of the Annual Report is available on the SEC’s website, www.sec.gov , under the Company’s ticker symbol (“FTK”) or on Flotek’s website, www.flotekind.com .
Discontinued Operations	During the fourth quarter of 2016, the Company classified the Drilling Technologies and Production Technologies segments as held for sale based on management’s intention to sell these businesses. The Company’s historical financial statements have been revised to present the operating results of the Drilling Technologies and Production Technologies segments as discontinued operations. The results of operations of Drilling Technologies and Production Technologies are presented as “Loss from discontinued operations” in the statement of operations and the related cash flows of these segments have been reclassified to discontinued operations for all periods presented. The assets and liabilities of the Drilling Technologies and Production Technologies segments were reclassified to “Assets held for sale” and “Liabilities held for sale,” respectively, in the consolidated balance sheets through September 2017.
Revenue Recognition	Revenue Recognition The Company recognizes revenues to depict the transfer of control of promised goods or services to its customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. Refer to Note 5 — “Revenue from Contracts with Customers” for further discussion on Revenue. The Company recognizes revenue based on the Accounting Standards Codification (“ASC”) 606 five-step model when all of the following criteria have been met: (i) a contract with a customer exists, (ii) performance obligations have been identified, (iii) the price to the customer has been determined, (iv) the price to the customer has been allocated to the performance obligations, and (v) performance obligations are satisfied. Products and services are sold with fixed or determinable prices. Certain sales include right of return provisions, which are considered when recognizing revenue and deferred accordingly. Deposits and other funds received in advance of delivery are deferred until the transfer of control is complete. For certain contracts, the Company recognizes revenue under the percentage-of-completion method of accounting, measured by the percentage of “costs incurred to date” to the “total estimated costs of completion.” This percentage is applied to the “total estimated revenue at completion” to calculate proportionate revenue earned to date. As an accounting policy election, the Company excludes from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenues.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results could differ from these estimates.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassifications did not impact net loss .
Recent Accounting Pronouncements	Recent Accounting Pronouncements Application of New Accounting Standards Effective January 1, 2018, the Company adopted the accounting guidance in Accounting Standards Update (“ASU”) No. 2014-09, “ Revenue from Contracts with Customers .” This standard supersedes most of the existing revenue recognition requirements in U.S. GAAP under Accounting Standards Codification (“ASC”) 605 and establishes a new revenue standard, ASC 606. This new standard requires entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also requires significantly expanded disclosures regarding the qualitative and quantitative information of an entity’s nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted ASC 606 using the full retrospective method. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. Refer to Note 5 — “Revenue from Contracts with Customers” for further information surrounding adoption of this new standard. Effective January 1, 2018, the Company adopted the accounting guidance in ASU No. 2016-15, “ Classification of Certain Cash Receipts and Cash Payments. ” This standard addressed eight specific cash flow issues with the objective of reducing the existing diversity in practice. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. The Company applied this standard prospectively, where applicable, as there were no historical transactions affected by this implementation. Effective January 1, 2018, the Company adopted the accounting guidance in ASU No. 2017-01, “ Clarifying the Definition of a Business. ” This standard provided additional guidance on whether an integrated set of assets and activities constitutes a business. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. The Company applied this standard prospectively and, therefore, prior periods were not adjusted. In addition, the Company had no activity during the nine months ended September 30, 2018 that was required to be treated differently under this ASU than previously issued guidance. Effective January 1, 2018, the Company adopted the accounting guidance in ASU No. 2017-09, “ Scope of Modification Accounting .” This standard provided guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. The Company applied this standard prospectively and, therefore, prior periods presented were not adjusted. There were no changes to the terms or conditions of current share-based payment awards during the nine months ended September 30, 2018 . New Accounting Requirements and Disclosures In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, “ Leases .” This standard requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. The pronouncement is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period and should be applied using a modified retrospective transition approach, with early application permitted. In July 2018, the FASB issued ASU No. 2018-10 and ASU No. 2018-11, which provide codification and targeted improvements to the original guidance issued, as well as modifies the transition methods available upon adoption. The Company intends to adopt the new standard in the first quarter of 2019 and intends to elect the available practical expedients upon adoption. The Company is currently evaluating all potential leases, assessing system readiness, including software procured from third-party providers, and completing an analysis of information necessary to restate prior period consolidated financial statements, if applicable. The Company anticipates this standard will have a significant impact on the consolidated balance sheets. However, the adoption is not expected to have a significant impact on the consolidated statements of operations. The Company is continuing to evaluate the impact the pronouncement will have on the related disclosures. In June 2016, the FASB issued ASU No. 2016-13, “ Measurement of Credit Losses on Financial Instruments .” This standard replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In February 2018, the FASB issued ASU No. 2018-02, “ Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income .” This standard allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. The pronouncement is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted in any interim period. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In June 2018, the FASB issued ASU No. 2018-07, “ Improvements to Nonemployee Share-Based Payment Accounting .” This standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The pronouncement is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted no earlier than an entity’s adoption date of Topic 606. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-13, “ Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement .” This standard removes, modifies, and adds additional requirements for disclosures related to fair value measurement in ASC 820. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted in any interim period. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding combined with dilutive common share equivalents outstanding, if the effect is dilutive. Potentially dilutive securities were excluded from the calculation of diluted loss per share for the three and nine months ended September 30, 2018 and 2017 , since including them would have an anti-dilutive effect on loss per share due to the net loss incurred during the periods.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes financial assets and liabilities into the three levels of the fair value hierarchy. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value and bases categorization within the hierarchy on the lowest level of input that is available and significant to the fair value measurement. • Level 1 — Quoted prices in active markets for identical assets or liabilities; • Level 2 — Observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Significant unobservable inputs that are supported by little or no market activity or that are based on the reporting entity’s assumptions about the inputs.
Segment Information	Segment Information Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by chief operating decision-makers in deciding how to allocate resources and assess performance. The operations of the Company are categorized into two reportable segments: Energy Chemistry Technologies and Consumer and Industrial Chemistry Technologies. • Energy Chemistry Technologies designs, develops, manufactures, packages, and markets specialty chemistries used in oil and natural gas well drilling, cementing, completion, and stimulation. In addition, the Company’s chemistries are used in specialized enhanced and improved oil recovery markets. Activities in this segment also include construction and management of automated material handling facilities and management of loading facilities and blending operations for oilfield services companies. • Consumer and Industrial Chemistry Technologies designs, develops, and manufactures products that are sold to companies in the flavor and fragrance industry and the specialty chemical industry. These technologies are used by beverage and food companies, fragrance companies, and companies providing household and industrial cleaning products. The Company evaluates performance based upon a variety of criteria. The primary financial measure is segment operating income. Various functions, including certain sales and marketing activities and general and administrative activities, are provided centrally by the corporate office. Costs associated with corporate office functions, other corporate income and expense items, and income taxes are not allocated to reportable segments.

Performance obligation, description of timing			Practical Expedients and Exemptions The Company has elected to apply several practical expedients as discussed below: Sales commissions are expensed when incurred because the amortization period would have been one year or less. These costs are recorded within segment selling and administrative expenses. The majority of the Company’s services are short-term in nature with a contract term of one year or less. For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14, exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. The Company’s payment terms are short-term in nature with settlements of one year or less. The Company has utilized the practical expedient in ASC 606-10-32-18, exempting the Company from adjusting the promised amount of consideration for the effects of a significant financing component given that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. In most service contracts, the Company has the right to consideration from a customer in an amount that corresponds directly with the value to the customer of the Company’s performance completed to date. For these contracts, the Company has utilized the practical expedient in ASC 606-10-55-18, allowing the Company to recognize revenue in the amount to which it has a right to invoice. Accordingly, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed.
